Anstalten Hall utanför Södertälje tillhör säkerhetsklass A, vilket innebär att de intagna utgör en hög risk för allmänheten. De anställda har därmed ett stort ansvar i att upprätthålla säkerheten på anstalten. Syftet med föreliggande studie var att undersöka möjliga samband mellan kriminalvårdarnas personlighet, deras upplevelse av säkerhetsklimatet och upplevda incidenter. Vidare studerades könsskillnader avseende personlighetsdrag och upplevelse av säkerhetsklimat. För att undersöka detta användes säkerhetsformuläret NOSACQ-50 och personlighetsskalan Swedish universities Scales of Personality (SSP). Totalt ingick 30 deltagare i studien. Signifikanta samband fanns mellan personlighetsdragen misstroende, bitterhet, somatisk ångestbenägenhet, social konformitet och verbal aggressionsförmåga i förhållande till hur de anställda upplevde säkerhetssystemet samt ledningen och kollegornas säkerhetsarbete. Signifikanta skillnader i personlighetsdragen fanns endast mellan mäns och kvinnors somatiska ångestbenägenhet, där kvinnor hade utmärkande högre värden. I övrigt visades inga signifikanta skillnader mellan personlighetsdragen. Vad det gällde upplevelser av säkerhetsklimatet på anstalten mellan könen kunde vissa skillnader utläsas, men dessa var inte signifikanta. Resultaten antyder att människor som arbetar inom kriminalvården är ganska lika varandra och att personlighetsdrag till viss del kan inverka på upplevelsen av arbetsplatsens säkerhetsklimat. Då antalet deltagare är begränsat bör dock slutsatser dras med försiktighet.

The prison Hall near Södertälje has safety class A. This means that prisoners constitute a high risk to the public and the employees have a great responsibility in maintaining security at the prison. The purpose of this study was to explore possible relationships and differences between the prison officers’ views on safety climate and their personal traits. Furthermore gender differences in personality traits and experience of safety climate were studied. The security form NOSACQ-50 and Swedish universities Scales of Personality (SSP) were used. A total of 30 participants were included in the analysis. Significant correlations were found between the personality traits mistrust, embitterment, somatic trait anxiety, social desirability and verbal trait aggression in relation to how the employees experienced the safety climate. Significant differences in personality traits were found between male and female only in somatic trait anxiety, where women had distinctively higher values then men. When it came to perceptions of safety climate between the sexes some differences could be seen, but these were not significant. The results suggest that men and women working in prisons are quite similar and that personality traits may to some extent affect the experience of the workplace safety climate. As the number of participants is limited, however, care should be taken when making conclusions.

▼ A Euphorbia tirucalli L. (Euphorbiaceae) possui princípios ativos com atividades biológicas cientificamente comprovadas como antimicrobiana e anticancerígena. O objetivo do trabalho foi avaliar o perfil fitoquímico, as atividades antifúngica e citotóxica dos extratos hexano, acetato de etila e etanólico dos ramos de E. tirucalli Linn. O extrato hexânico foi submetido e analisado por Cromatografia Gasosa Acoplada a Espectrômetro de Massas (CG-MS). A atividade antifúngica foi realizada pelo método de microdiluição seguindo o protocolo M27-A3 frente Candida parapsilosis, C. albicans, C. glabrata; C. parapsilosis e C. krusei. A atividade citotóxica foi realizada através do ensaio de MTT frente as linhagens humanas HaCaT (queratinócitos), NCI-H292 (carcinoma mucoepidermoide de pulmão), HT-29 (adenocarcinoma de cólon), K562 (leucemia promielocítica aguda), HL-60 (leucemia mielocítica crônica), SCC9 (carcinoma epidermoide de língua), SCC15 (carcinoma epidermoide oral) e murino L929 (fibroblasto de camundongos). A avaliação cromatográfica sugere 14 substâncias: ácido undecanóico, palmítico, linoleico e esteárico, 9-octadecenoato de metila, fitol, octacosano, eicosano, lanosta-8,24-dien-3-ol, lanosterol e lupenona. O extrato etanólico apresentou melhor atividade frente a todos os isolados de candida ssp. causando redução significativa nas maiores concentrações testadas (64 μg/mL). O teste de citotoxicidade mostrou inibição acima de 75 % frente a linhagem HL-60, valor esse usado como critério para determinar a CI50, que apresentou valor de 1,38 μg/mL frente ao extrato hexânico. Concluí-se que o extrato etanólico apresenta capacidade de inibir o crescimento de leveduras do gênero Candida, sugerindo a possibilidade de desenvolvimento de novos fármacos antifúngicos, assim como o extrato hexânico apresentou-se como promissor para o desenvolvimento de novos fármacos anticâncer.

▼ A talaj növekedő sótartalma napjaink egyik globális problémájává nőtte ki magát. A száraz és félszáraz területek a leginkább érintettek, de Magyarországon is égető probléma a szikesedés és a sófelhalmozódás. Az említett környezeti probléma egyik nagy elszenvedői a növények, melyek anyagcseréjét alapvetően módosítja a megnövekedett sókoncentráció. A stresszhatás növekedésgátlásban, de súlyosabb esetben a membrántranszportban és fotoszintézis folyamatainak gátlásában is megnyilvánul. Fontos tehát, hogy minél több növény sóérzékenységét feltérképezzük. A Crocusok Magyarországon kedvelt kerti növényként ismertek leginkább, azonban ökológus szemmel a természetben nyíló vad fajok értékesek igazából. Genetikai diverzitásuk megőrzését segíti, ha minél több információt meg tudunk állapítani életciklusukról, igényeikről. A Crocus sativus L. egy steril, triploid, csak emberi kultúrákban létező faj, agronómiai szempontból azonban igen értékes, hiszen szárított, porrá zúzott bibéje a világ legdrágább fűszereként számon tartott sáfrány. Újabban egyéb betegségek mellett a rákkutatás egyik fontos kutatási alanya is. A kísérleti munka az olaszországi Catania Agrártudományi Egyetemének kísérleti telepének üvegházában folyt. A magas sótartalom hatását vizsgáltam a külső virágkörön ülő lepellevelek hosszúságára és szélességére, a belső virágkörön ülő lepellevelek hosszúságára és szélességére, illetve a portok, a porzó és a bibe hosszára a következő tavasszal virágzó Crocus fajokon : Crocus versicolor, Crocus corsicus, Crocus olivieri, Crocus korolkowi, Crocus fleischeri, Crocus biflorus, Crocus minimus. Ezenkívül vizsgáltam még a növekedő sókoncentráció a virágzási periódusban az összes virág számára gyakorolt hatását. Ezekbe a kísérletekbe bevontam még további 7 ősszel virágzó Crocus fajt, melyek a következők voltak: Crocus ligusticus, Crocus goulimyi, Crocus laevigatus, Crocus serotinus, Crocus vernus, Crocus specoius és a Crocus sativus L., a fűszersáfrány. Összességében megállapíthatjuk, a Crocus fajok reproduktív szerve érzékeny a talaj növekedő sókoncentrációjára. Problémát jelenthet ez a száraz és félszáraz területeken termesztett és vad fajok számára. A Debreceni Egyetem Növénytani Tanszéke, más Európai Uniós tagállamok egyetemeivel együtt, részt vesz az úgynevezett Crocusbank projekt elnevezésű kutatási pályázatban, melynek alapvető célkitűzése Crocus fajok génbankjának létrehozása, genetikai diverzitásuk megőrzése, a génbankba bekerült és ott szaporított növények molekuláris karakterizálása. A diplomamunkában bemutatott kísérleti eredmények is részét képezik ennek a pályázati tevékenységnek. Advisors/Committee Members: Surányi, Gyula (advisor).

The nematodes of the genus Ancylostoma are endoparasites of dogs and also zoonotic geohelminths that can infect humans. The control these nematodes in adult stage is based on the use of anthelmintics. However, the use of biocontrol agents may be an additional action to reduce the population in pre-parasitic stages developing in the environment. This study aimed to evaluate the Duddingtonia flagrans predator fungus for the control of the larval form (L3) of Ancylostoma spp., in beach sand. We evaluated the in vitro infectivity of two isolates of the nematophagous fungus D. flagrans (AC001 and CG768) on infective larvae (L3) of Ancylostoma spp. dogs. Vegetative structures (mycelium), reproductive (conidia) and survival (chlamydospores) were used as fungal inoculum. The interaction was evaluated at the end of 10 days of incubation in Petridishes containing agar-water 2% medium in a temperature of 25 C. The antagonism in semi-natural conditions was assessed by use of a mass production of fungal inoculum in grains of milled maize. The fungus was introduced into the sand in colonized milled maize at the concentration of 15,000 chlamydospores / gram of sand. This concentration was the most effective in the preliminary in vitro assay (reduction of 59.2%). The results showed the efficiency of the fungus D. flagrans in the control of infective larvae of Ancylostoma spp. in beach sand. This suggests that isolates of this fungus may be used as part of a control program of Ancylostoma spp. in the environment.

Os nematóides do gênero Ancylostoma são endoparasitas de cães e também geohelmintos zoonóticos que podem infectar o ser humano. O controle destes nematóides em estágio adulto é baseado na utilização de anti-helmínticos. No entanto, o uso de agentes biocontroladores pode ser uma medida complementar para reduzir a população em estágios pré-parasitários em desenvolvimento no ambiente. Este estudo objetivou avaliar o fungo predador Duddingtonia flagrans no controle da forma larval infectante (L3) de Ancylostoma spp., em areia de praia. Foi avaliada a infectividade in vitro de dois isolados do fungo nematófago D. flagrans (AC001 e CG768) sobre larvas infectantes (L3) de Ancylostoma spp. de cães. Utilizou-se como inóculos fúngicos estruturas vegetativas (micélio), reprodutivas (conídios) e de sobrevivência (clamidósporos). A interação foi avaliada ao final de 10 dias de incubação em placas de Petri contendo meio ágar-água 2% em temperatura de 25 C. O antagonismo em condições semi-naturais foi avaliado por meio da utilização de uma produção massal de inóculo fúngico em grãos de milho moído. O fungo foi incorporado à areia, em grãos colonizados de milho moído na concentração de 15.000 clamidósporos/grama de areia. Essa concentração se mostrou a mais efetiva em ensaio in vitro preliminar (redução de 59,2%). Os resultados mostraram a eficiência do fungo D. flagrans no controle de larvas infectantes de Ancylostoma spp. em areia de praia. Isso sugere que isolados desse fungo podem ser utilizados como parte de um programa de controle…

▼ Les méthodes traditionnelles de gestion des renouées asiatiques (Fallopia spp.), plantes invasives parmi les plus menaçantes au monde, ont des résultats mitigés et coûteux. Certains gestionnaires s'orientent donc vers des solutions alternatives comme le génie végétal. Ordinairement utilisé contre l'érosion des berges de cours d'eau, il permet également d'installer un couvert végétal rapidement et durablement. Un des enjeux pour le contrôle des renouées asiatiques est donc d'optimiser ces méthodes afin de reconstituer des communautés végétales capables de les réguler. Ce travail de thèse tente de répondre à cet enjeu en apportant une meilleure compréhension du rôle des interactions biotiques dans la régulation des renouées asiatiques.Dans ce projet, nous nous sommes intéressés aux populations déjà installées de renouées asiatiques et donc aux facteurs qui interviennent en tant que régulateur de leur performance. Les renouées asiatiques étant plus rares en forêts structurées et étant connues comme des espèces pionnières dans leur aire d'origine, l'hypothèse est que la compétition, en particulier pour la lumière, joue un rôle central dans la régulation de leur performance. L'objectif du travail de thèse a été de vérifier cette hypothèse, en évaluant le rôle de la lumière dans la performance des renouées asiatiques (chapitre 1), en étudiant le rôle des interactions biotiques de type compétition (chapitre 2) et en évaluant l'effet inhibiteur de la renouée du Japon sur des boutures de Salicaceae en fonction de la lumière disponible (chapitre 3). Le premier chapitre met en évidence, par des mesures in situ, l'importance de la quantité de lumière sur la production de biomasse aérienne des renouées asiatiques, comparativement à d'autres facteurs liés aux perturbations ou aux conditions édaphiques (partie 1). Une expérimentation en conditions semi-contrôlées dans laquelle des renouées asiatiques ont été cultivées et soumises à un gradient de lumière complète ces résultats (partie 2). Elle met en évidence leur plasticité phénotypique ainsi que l'existence de différents seuils de lumière pour la production de biomasse, l'allocation des ressources ou leurs effets compétitifs.Le deuxième chapitre s'intéresse plus spécifiquement aux interactions compétitives et en particulier à la compétition pour la lumière. La première partie démontre, par l'évaluation in situ de la performance des renouées asiatiques le long de gradients environnementaux, le rôle prépondérant de la structure fonctionnelle de la communauté végétale. La deuxième partie s'appuie sur une expérimentation en microcosme et montre les effets compétitifs respectifs du saule des vanniers (espèce prometteuse pour le contrôle des renouées asiatiques) et de la renouée du Japon. Enfin, le dernier chapitre de la thèse s'intéresse plus spécifiquement aux effets allélopathiques de la renouée du Japon sur des boutures de différentes espèces de Salicaceae. Une première analyse met en évidence des effets phytotoxiques différentiels entre les espèces de Salicaceae (partie 1).

The utilization of pasteurized Milk to coalho cheese process guarantees the product quality on the microbiological aspect. In this case, it needs the addition of lactic culture and so that, the product comes out with differing sensorial characteristics. The objective of this work was to evaluate the coalho cheese quality, produced by adding lactic culture endogen using coalho cheese. The objective of this work was to evaluate the coalho cheese quality produced by adding endogen lactic culture utilizing the Quantities Descriptive Analysis (QDA), test of acceptability and analysis of some physical-chemical parameters. It was utilized three lactic cultures: LA-02 (Lactobacillus acidophilus); RE-02 (Lactococcus ssp) and Blend (Lactococcus ssp + Lactobacillus acidophilus). The team of QDA was with eleven people to judge it. The acceptability utilized fifty consumers previously selected by a questionnaire. The physical-chemical parameters evaluated were: humidity, ashes, base dried fat, proteins, ph, acidity and cloret. The cheese acceptability produced by LA-02 and Blend presented the highest results to the attributes flavor, 7.38 and 6.92, respectively. By the QDA were considered 13 describing terms to coalho cheese. The display of Blend was characterized by its yellow color, hardness, typical coalho cheese smell, typical coalho cheese flavor, consistency and chewing. The cheese produced by LA-02 was characterized by its acid flavor, homogeneity and softness. The three displays evaluated presented values of humidity and fat according to the legislation exigency. The LA-02 and Blend cultures were the ones which better developed the coalho cheese characteristics.

A utilização de leite pasteurizado, para processamento de queijo coalho, garante a qualidade do produto sob o aspecto microbiológico. Neste caso, é necessária a adição de culturas láticas, que irão conferir ao produto características sensoriais diferenciadas. Este trabalho teve como objetivo avaliar a qualidade de queijo de coalho produzido com adição de diferentes culturas láticas endógenas utilizando a Análise Descritiva Quantitativa (ADQ), teste de aceitabilidade e análise de alguns parâmetros físico-químicos. Foram utilizadas três culturas láticas: LA-02 (Lactobacillus acidofilus); RE-02 (Lactococcus ssp) e Blend (Lactococcus ssp + Lactobacillus acidofilus). A equipe da ADQ foi composta por 11 julgadores treinados. No teste de aceitabilidade utilizou-se 50 consumidores previamente selecionados por questionário. Os parâmetros físico-químicos avaliados foram: umidade, cinzas, gordura em base seca, proteínas, pH, acidez e cloretos. A aceitabilidade dos queijos produzidos pelo LA-02 e Blend foram maiores para os atributos sabor, 7.38 e 6.92 e, respectivamente. Pela ADQ foram levantados 13 termos descritores para queijo coalho. A amostra Blend foi caracterizada pela cor amarela, firmeza, aroma típico de queijo de coalho, sabor típico de queijo de coalho, elasticidade e mastigabilidade. O queijo produzido com LA-02 foi caracterizado pelo sabor ácido,…

Der Haupthistokompatibilitätskomplex wird im Schwein durch die Klasse I und Klasse II Swine Leukocyte Antigen (SLA) Gencluster kodiert. Die hochpolymorphen SLA Gene kodieren für eine Reihe von Glykoproteinen, deren Aufgabe darin besteht, prozessierte Peptidantigene auf der Oberfläche von Zellen zu präsentieren und anschließend in T-Zellen eine entsprechende Immunantwort auszulösen. Somit stellen SLA Genprodukte eine der wichtigsten Determinanten innerhalb der porcinen Immunantwort auf Infektion und Vakzination dar. Die Mehrheit der in Österreich für die Fleischerzeugung verwendeten Schweinerassen stellt eine F2 Generation dar. Diese Tiere sind Nachkommen einer F1 Generation der Edelschwein/Landrasse, die mit Pietrain-Ebern gepaart wird. Somit ist das SLA Allel- und Haplotypen-Repertoire in der Nachkommenschaft festgelegt und aufgrund des Repertoires der Elterntiere begrenzt. Diese Arbeit beschreibt sowohl die Charakterisierung der SLA Klasse I (SLA1, SLA2, SLA3) als auch der Klasse II (DRB1, DQB1, DQA) Gene von 27 reinrassigen Pietrain Schweinen anhand der Sequenz-basierten (SBT) und der PCR-basierten Methode unter der Verwendung von sequenzspezifischen Primern (PCR-SSP). Insgesamt wurden 15 Klasse I und 12 Klasse II Haplotypen in dieser Gruppe von Schweinen identifiziert. Der häufigste auftretende SLA Haplotyp ist Lr-43.13 (SLA-1*11XX-SLA-3*04XX-SLA-2*04XX-DRB1*0901-DQB1*0801-DQA*03XX) der in sieben Individuen in einer Frequenz von 13,0% detektiert wurde. Zusätzlich wurden drei Klasse I und zwei Klasse II Haplotypen ermittelt, die bisher noch in keiner Schweinepopulation charakterisiert wurden. Dies lässt den Schluss zu, dass die Pietrain Rasse eine zuchtspezifische Einschränkung der SLA Gendiversität aufweist. Die Ergebnisse dieser Arbeit können zu einem besseren Verständnis der Beeinflussung der SLA Gene auf unterschiedliche immunologische und pathophysiologische Bedingungen führen. Weiters ist es möglich, effektivere Impfstoffe herzustellen, um somit die gesundheitliche Fitness der in Österreich vorkommenden Schweinepopulation zu erhöhen.

The porcine major histocompatibility complex (MHC) harbours the SLA (swine leukocyte antigen) class I and II gene clusters. The SLA genes are highly polymorphic; they encode a series of cell-surface glycoproteins which function mainly in presenting antigenic peptides to T cells, therefore representing one of the most important determinants in swine immune response to infectious disease and vaccination. In Austria, the majority of commercial pigs are F2 descendants of F1 Large White/Landrace hybrids paired with Pietrain boars. The repertoire of SLA alleles and haplotypes present in Pietrain pigs thus has an important influence on that of their descendants. In this study, we characterized the SLA class I (SLA1, SLA2, SLA3) and class II (DRB1, DQB1, DQA) genes of 27 purebred Pietrain pigs using a combination of the high-resolution sequence-based typing (SBT) method and a low-resolution PCR-based method using allele-group sequence-specific primers (PCR-SSP). A total of…

V naši raziskavi, ki je potekala v letu 2018 na Fakulteti za kmetijstvo in biosistemske vede Maribor (laboratorij za genetiko), smo primerjali dve različni metodi izolacije DNA: klasično metodo CTAB (cetil trimetil amonijev bromid) in metodo CTAB z dodanim PVP (polivinilpirolidon), proteinazo in RNazo, ki smo jo poimenovali metoda PVP. Oba protokola smo uporabili pri dveh rastlinskih vrstah: pri slivah (Prunus domestica L.) in pri bezgu (Sambucus spp.). Izolacijo DNA smo izvajali v pomladnih in jesenskih mesecih, saj nas je zanimala razlika v količini in čistosti izolirane DNA v povezavi s starostjo oziroma zrelostjo rastlinskih tkiv (listov). Ugotovili smo, da je koncentracija izolirane DNA bezga in sliv višja pri rastlinskem materialu, ki je bil nabran v pomladanskem obdobju, kot pa pri listih, ki so bili nabrani v septembru. Ugotovili smo tudi, da izbira genotipa vpliva na koncentracijo izolirane DNA. Rezultati namreč kažejo, da smo večjo količino DNA izolirali pri bezgu, saj je bila povprečna izmerjena koncentracija DNA pri bezgu 496,4 ng/μl, pri slivah pa 69,34 ng/μl.

In our study, which took place in 2018 at the Faculty of Agriculture and Life Sciences Maribor (Genetics Laboratory), we compared two different methods of DNA isolation: the classic CTAB method (cetyl trimethyl ammonium bromide) and the CTAB method with added PVP (polyvinylpyrrolidone), proteinase, and RNase, which we named the PVP method. Both protocols were used in two plant species: in plums (Prunus domestica L.) and in elder (Sambucus spp.). The isolation of DNA was carried out in the spring and autumn months as we were interested in the difference in the amount and purity of isolated DNA in relation to the age or maturity of plant tissues (leaves). We found that the concentration of isolated elder and plum DNA was higher in the plant material collected during spring period than in the leaves that were collected in September. We also found that the genetic structure (genotype) affected the concentration of isolated DNA. The results indicate that a greater amount of DNA was isolated in elder

the mean measured DNA concentration of elder was 496.4 ng/μl and 69.34 ng/μl for plums.

O ferro é um micronutiente essencial em plantas, como também para praticamente todos os demais organismos. Porém, as formas livres de ferro intracelular podem ser extremamente danosas. A proteína ferritina tem papel crucial neste contexto, com a função de acumular ferro de uma forma segura e biodisponível. Cada proteína pode acumular aproximadamente 4500 átomos de ferro em sua cavidade interna. Em plantas, existe um número variado de cópias gênicas para ferritina e estas cópias têm expressão modulada por fatores bióticos e abióticos. No genoma do arroz foram caracterizadas duas cópias para o gene da ferritina. Como existem poucos estudos funcionais para ferritina em arroz, este trabalho teve como objetivos: (a) silenciar as duas cópias da ferritina da subespécie japonica variedade Nipponbare; (b) caracterizar, por PCR, mutantes para ferritina por inserção do retroelemento TOS17; (c) caracterizar a expressão da ferritina da subespécie de arroz japonica, variedade Nipponbare, em plantas cultivadas em meio hidropônico sob excesso de ferro. Utilizando o sistema Gateway (Invitrogen) nós desenvolvemos uma construção que expressa um RNA em grampo projetado para silenciar ambas as cópias dos genes da ferritina de arroz. Baseando-se em um protocolo bem estabelecido de regeneração de plantas transgênicas de arroz, nós regeneramos plantas transgênicas silenciadas para os genes da ferritina. Foi obtido 75% de sucesso na geração das plantas silenciadas, o que está de acordo com a literatura. Os transformates primários (T0) não apresentaram anormalidades morfológicas evidentes. É possível que uma rota compensatória para armazenar ferro de forma segura seja ativada quando os níveis de ferritina são diminuídos. Além disso, as plantas produzidas neste trabalho são uma ferramenta potencial para estudar a relação ferro-planta. Baseando-se em análises in silico e por PCR, nós caracterizamos três linhagens mutantes contendo inserção do retroelemento TOS17 no gene OsFer2, entretanto, ainda não identificamos mutantes homozigotos. Em plantas de arroz crescidas em meio hidropônico, o aumento da concentração de ferro resultou em maiores níveis de expressão de ferritina, avaliados por RT-PCR semi-quantitativo, após 6 h e 12 h de exposição aos tratamentos de 50 e 500 ppm de FeSO4 do que na condição controle (5,6 ppm).

Iron is an essential micronutrient for plants, as for virtually all organisms. However, free intracelular iron forms can be extremely dangerous. The ferritin protein has a crucial role in this context, storing iron in a safe and bioavailable form. Each protein molecule can accumulate about 4500 iron atoms in its internal cavity. In plants, there is a variable number of ferritin gene copies and their expression is modulated by biotic and abiotic factors. There are two copies of the ferritin gene in the rice genome. As there are few functional studies for the ferritin genes in rice, this work had the objetives of: (a) to silence both copies of the ferritin genes in the japonica Nipponbare variety; (b) to identify and…

▼ In this thesis, organometallic complexes with main-group elements were used as single-source precursors (SSPs) to homometallic, heterobimetallic, and heterobimetallic/hetero-main group element transition metal pnictide (TMPn) thin films grown by metal-organic chemical vapor deposition (MOCVD) from synthesized SSPs and blends of SSPs. Films grown on conductive substrates were shown to be active electrocatalysts for water splitting catalysis while films grown on semiconducting substrates could be used to split water photoelectrocatalytically. Films of heterobimetallic transition metal phosphide FeMnP in its hexagonal phase were grown on a variety of substrates from SSP FeMn(CO)8(µ-PH2). It was also observed that films grown on quartz suffered from Mn oxidation due to non-innocent interaction with the substrate, which could be avoided by using alumina as a substrate owing to its relative inertness. Films of FeMnP grown on nickel foam and graphene-wrapped nickel foam were evaluated as water-splitting catalysts. The electrodes catalyzed both the hydrogen and oxygen evolution reactions at an ultra-low voltage of 1.51 V for 10 mA·cm-2 of current density and with stable performance. Films of FeMnP grown on an electrode consisting of a titanium dioxide nanorod array on fluorine-doped tin oxide achieved the theoretical photocurrent density for rutile TiO2 with high Faradaic efficiency for photoelectrochemical oxygen evolution and excellent stability. Additionally, electrodes were prepared by the SSP-MOCVD growth of FeP and Fe2P and compared to similarly prepared Fe3P. Evaluation of their catalytic activity towards the hydrogen evolution reaction showed activity to follow the trend Fe3P > Fe2P > FeP. Organometallic synthesis was directed at developing a precursor to (Fe1-xMnx)2(As,P) leading to the discovery of two suitable SSPs, {FeMn(CO)8}(µ4-As){Fe2(CO)7PtBuH2} and {FeMn(CO)8}(µ4-As){Fe2(CO)6(µ-CO)(µ-PtBuH)}, which were used to successfully grow (Fe1-xMnx)2(As,P) on quartz. 18 new organometallic clusters containing mixtures of Fe, Mn, As, and P were prepared and characterized en route to the ultimate SSPs.

▼ Le développement de variétés performantes de blé dur (Triticum turgidum durum) doit prendre en compte la corrélation négative entre rendement et teneur en protéines (GPC). Une meilleure compréhension de ce phénomène nécessite une connaissance de l'élaboration des composantes de ces variables. Au cours de cette thèse nous nous sommes focalisés sur l'étude du déterminisme de paramètres foliaires pendant le remplissage du grain (morphologie, résorption d'azote/senescence) ainsi que leurs relations avec les caractéristiques post-récolte (rendement, GPC). La population d'étude est constituée de 282 lignées recombinantes issues d'un croisement demi-diallèle entre quatre lignées élites. Les données proviennent d'expérimentations menées en milieu contrôlé (3 expérimentations) et en plein champ (2 essais).En milieu contrôlé, plusieurs variables (teneur en azote, masse surfacique) ont été prédites par spectrométrie infrarouge à raison de mesures régulières au cours de la période d'intérêt. La résorption d'azote de la dernière feuille a été modélisée pour chaque génotype dont les paramètres ont été analysés. Un lien négatif fort a été établi entre la date d'initiation de la résorption (t0) en temps thermique post-floraison et sa durée et un lien positif entre cette date clé et le poids individuel des grains. A l'échelle de la parcelle, le suivi dynamique de la senescence par la mesure d'évolution d'un indice de végétation, le NDVI (Normalized Difference Vegetation Index) a montré une relation forte entre vitesse d'évolution de la senescence et son ordonnée à l'origine, suggérant que la fin de la senescence était un phénomène très contraint dans les conditions environnementales de plein champ.En absence de stress azoté, l'analyse des 4 géniteurs a montré que des combinaisons linéaires de paramètres foliaires permettaient d'expliquer environ 2/3 des variations de la production en grains d'un épi et de la GPC. En considérant l'ensemble de la population, les effets antagonistes d'une résorption tardive sur la production de grains et la teneur en protéines ont été établis. Une carence en azote appliquée post-floraison provoque une résorption précoce et longue, ce qui semble d'avantage affecter la GPC que le rendement. Une carence en azote appliqué pré-floraison réduit la quantité d'azote disponible dans les feuilles drapeau (et par conséquent leur potentiel photosynthétique) ainsi que le nombre de grains alors que les apports tardifs en azote réalisés dans ce traitement vont retarder la résorption donc augmenter le poids individuel des grains et la GPC. L'analyse génétique en modèle mixte a permis de prendre en compte un apparentement entre lignées, calculé grâce aux pedigrees ou aux marqueurs. Ces deux estimateurs de l'apparentement sont très fortement corrélés ; l'ordonnée à l'origine de la relation (0.3) pouvant être interprétée comme une mesure de l'identité par état de la population de base à partir de laquelle les géniteurs sont issus. Par conséquent, les variances additives issues d'un apparentement marqueurs sont… Advisors/Committee Members: David, Jacques (thesis director), Roumet, Pierre (thesis director).

Durant ces dernières décennies, les systèmes enzymatiques de dégradation du bois sécrétés par les champignons ont fait l’objet de nombreuses études aboutissant à la caractérisation fonctionnelle et biochimique des enzymes extracellulaires majeures agissant directement sur le polymère. Cependant, les systèmes annexes associés au processus de dégradation n’ont à l’heure actuelle été que peu étudiés. En particulier, les systèmes de détoxication et de réponses des champignons au stress généré par le processus de dégradation ainsi que les mécanismes lui permettant de croître dans cet environnement hostile sont encore peu connus. Ce stress est majoritairement dû à la présence de radicaux et d’extractibles. Les extractibles sont des molécules issues du métabolisme secondaire de l’arbre qui sont synthétisés pour augmenter la durabilité du bois face aux attaques biotiques et abiotiques. Une analyse transcriptomique réalisée au laboratoire a mis en évidence la surexpression de gènes codant des petites protéines sécrétées (SSP) chez Phanerochaete chrysosporium lors d’une culture en présence d’extractibles de chêne. La fonction de ce type de protéines chez les champignons lignolytiques est inconnue. Mon projet de thèse a porté sur la caractérisation d’une de ces SSP (SSP1). Les résultats obtenus ont révélé des propriétés biochimiques atypiques pour cette protéine qui est capable de former une structure fibrillaire, notamment grâce à la présence d’un domaine C-terminal riche en alanine et glycine. De plus, nous avons pu montrer que cette protéine présentait une activité β-glucuronidase in vitro, qui est dépendante de son état d’oligomérisation. Une approche physiologique a également été abordée grâce à l’obtention de mutants knock-out de SSP de Podospora anserina. La caractérisation de ces mutants a montré un défaut de croissance en condition de stress oxydant et en présence de molécules perturbant l’intégrité de la paroi cellulaire. Enfin, une analyse in silico des orthologues de SSP1 a montré la présence de ce gène dans les génomes d’organismes saprophytes, ectomycorhiziens ou pathogènes suggérant un rôle indirect de cette protéine dans les processus de dégradation du bois, probablement en lien avec la gestion du stress associé

During the last decades, the enzymatic systems involved in wood degradation have been intensively studied in fungi. This has led to functional and biochemical characterization of the main extracellular enzymes that are involved in the process. However, other systems associated to the degradation mechanisms have been poorly studied. In particular, the detoxification and stress response pathways allowing the fungus to grow in and resist the toxic conditions that are associated to the degradative process are still unknown. This stress is mostly due to the presence of radicals and extractives. Extractives are putative toxic compounds produced as secondary metabolites in tree to enhance wood durability against biotic and abiotic attacks. A transcriptomic analysis performed in the laboratory highlighted the…

▼ Brown-heart disorder in rutabaga is a boron deficiency syndrome that renders the inside of the roots brown and makes the crop unfit for market. The connection between boron deficiency and brown-heart was first reported in 1930’s. Brown-heart continues to be a concern for rutabaga growers all over the World, especially in Northern Europe, Canada, United States of America and New Zealand. The aim of this thesis was to compare the effects of various methods of applying boron, in terms of rutabaga yield and brown-heart. The field experiments were done in 2013 and 2014 on Räpi research farm of Apetit Ruoka Oyj in municipality of Köyliö, as part of collaboration between Apetit Ruoka Oyj and Yara Suomi Oyj. The companies aimed to find the best fertilizer solution for the prevention of brown-heart in rutabagas. Treatments were either fertilizer placement or broadcast application. In addition, foliar spraying treatment was used. Nutrient levels of the soil were analysed before planting and after harvest. The nutrient levels of rutabaga leaves before harvest, and nutrient levels of rutabaga roots by the time of harvest, were analysed. Additionally, the yield and number of rutabagas with brown-heart were determined. In experiments done in 2013, the effect of boron treatment on yield was statistically insignificant. In 2014, the fertilizer placement increased the yield as compared to broadcast application. In 2013 the number rutabagas with brown-heart disorder was significantly less within the samples treated with fertilizer placement, as compared to samples treated with broadcast applications. In 2014 the overall number of rutabagas with brown-heart was low, and the differences between treatments were statistically insignificant. Of the rutabaga boron treatments compared in this thesis, the fertilizer placement was more efficient than the broadcast application. Generally, the effect of foliar spraying treatment on yield or quality of the rutabagas was insignificant. In order to achieve high quality rutabaga crop, applying boron with fertilizer placement simultaneous to sowing, is recommended.

▼ Since the beginning of the 20th century, there has been a significant interest in the field of applied sciences. New and innovative technologies have been invented, leading to the significant improvement of the human life. But unfortunately, these achievements came with a cost. The chemical wastes, the toxic solvents, the byproducts and the production of greenhouse gasses had a significant impact on the environment the results of which are still visible till the present day. For this reason, the last century has been a systematic study for the replacement of the toxic solvents with new ones, environmentally friendly and less harmful such as supercritical fluid extraction, subcritical water extraction, accelerated solvent extraction, microwave assisted extraction and others, many of which have already found the way to the industrial applications. The subject of the present doctorat thesis was the study of optimization and the implementation of environmentally friendly extraction processes for the production of bioactive extracts from plants with significant pharmacological characteristics, using modern and innovative extraction technologies, such as supercritical CO2, accelerated solvent extraction and subcritical water extraction. For that, three different plant species were collected from different regions of Greece and were studied: Sideritis raeseri ssp. attica, Cistus creticus ssp. creticus and the roots of Glycyrrhiza glabra. The aim of this work was the application of the aforementioned techniques for the production of extracts that will exhibit: high yields, high antioxidant activity and significant phenolic and flavonoid content.The first plant was the aerial parts of Sideritis raeseri ssp. attica, a plant well known in Greece for its pharmacological activities, especially for its use in the treatment of colds and coughs. In order to extract the majority of the active metabolites, a sequential use of solvents is needed, such as: dichloromethane, methanol and water. The aim of this study was the substitution of these solvents with environmentally friendly ones like supercritical CO2, ethanol and water, without the decrease of the extract’s activity. This substitution led to extracts that exhibit higher yields, increased antioxidant activity and higher phenolic and flavonoid content only through the use of environmentally friendly procedures. Subsequently, the extract with the highest activity was subjected to further phytochemical analysis in order to isolate and characterize its major metabolites. The isolation led to the identification of lavandulofolioside, acteoside, hypolaetin 7-O-6΄΄΄-O-acetyl-β - D - allopyranosyl - (1→2) -β - D–glucopyranoside, leonoside A, isoscutellarein 7-O-6΄΄΄-O-acetyl- β-D- allopyranosyl-(1→2)-β-D- glucopyranoside and 4΄-Ο-methylhypolaetin 7-O-6΄΄΄-O-acetyl- β-D- allopyranosyl-(1→2)-β-D- glucopyranoside, from whom leonoside A was isolated for the first time from the Sideritis genus.The second plant studied in this dissertation was Cistus creticus ssp. creticus, an endemic…

▼ A mastite bovina, inflamação da glândula mamária, é uma das principais doenças que acomete o rebanho leiteiro em todo o mundo. O principal agente infeccioso responsável por esta enfermidade é o Staphylococcus aureus (S. aureus), bactéria de interesse na microbiologia dos alimentos como agente causador de intoxicações alimentares. Outro importante fato que envolve este microrganismo é a resistência aos antibióticos usados na terapêutica humana e veterinária. Como o leite e derivados são amplamente consumidos e podem conter S. aureus enterotoxigênicos e resistentes, objetivou-se com este estudo caracterizar feno e genotipicamente Staphylococcus spp. isolados de amostras de leite de vacas com mastite e queijos de coalho no Estado de Pernambuco. Para o diagnóstico da mastite bovina foram realizados os testes da caneca telada e o California Mastitis Test. As amostras de queijos de coalho foram submetidas ao isolamento e contagem de Staphylococcus coagulase positiva (SCP) em Ágar Baird-Parker. As cepas de Staphylococcus spp. obtidas tanto do leite quanto dos queijos foram caracterizadas fenotipicamente em S. aureus, SCP e Staphylococcus coagulase negativa (SCN), através da técnica de coloração de gram, características morfo-tintoriais das colônias e produção de hemólise em Ágar sangue, além de provas bioquímicas como fermentação da glicose em anaerobiose, fermentação do manitol em aerobiose e anaerobiose, produção de termonuclease, acetoína e coagulase. A caracterização genotípica foi realizada através da utilização da técnica de PCR-RFLP do gene coa, PCR-Uniplex e Multiplex para investigação dos genes toxigênicos, além de clivagem e seqüenciamento para confirmação da presença dos genes se. Para traçar o perfil de resistência dos isolados, foi empregada a técnica de difusão em ágar, utilizando diferentes antibióticos. Foram analisados 246 animais, totalizando 984 quartos mamários, dos quais, 562 (57,1%) apresentaram mastite subclínica, sendo os microrganismos mais prevalentes Staphylococcus spp. (36%), Corynebacterium spp. (34,8%) e S. aureus (13,6%). O perfil de sensibilidade antimicrobiana demonstrou que das 59 cepas de SCP isoladas de leite, 28,5% foram resistentes, sendo os antibióticos menos eficazes a penicilina e a amoxicilina. A caracterização das cepas de S. aureus de casos de mastite bovina pela técnica de PCR-RFLP revelou a presença de dois perfis genotípicos, P1=750pb e P2=1000pb. Das 81 cepas de Staphylococcus spp. isoladas de leite de vacas com mastite, 65 (80,2%) comportavam genes toxigênicos, sendo os genes se encontrados (seg, seh, sei e sej). Com relação aos queijos de coalho, das 10 amostras avaliadas, 90% estavam fora dos padrões permitidos pela legislação para SCP. 18/20 das cepas de Staphylococcus spp. apresentaram os genes tst, sec, sed, seg, seh, sei e sej. O percentual de resistência entre as cepas isoladas de queijo foi baixo. A análise de restrição e o seqüenciamento confirmaram a presença dos genes se nos isolados de leite e queijo. A tipagem molecular permitiu compreender o padrão de dispersão… Advisors/Committee Members: Lúcia Montenegro Stamford, Tânia (advisor).

São encontradas em território brasileiro, cerca de 10% das espécies descritas em todo o planeta. Mesmo reduzia e fragmentada, principalmente no estado de Pernambuco, a Mata Atlântica continua a ter importância vital por guardar um dos maiores índices de biodiversidade do mundo. O presente trabalho tem como objetivo identificar os constituintes químicos voláteis por CG-FID e CG/EM, obtidos por hidrodestilação a partir das folhas de Protium giganteum (PG) e P. aracouchine (PA), coletadas em um fragmento de Mata Atlântica conhecido por Mata da Cruzinha, localizada no Engenho São José, município de Igarassu, litoral Norte de Pernambuco. Os rendimentos dos óleos obtidos foram similares (PG = 0.050.09% e PA = 0.040.06%). A rotação específica revelou que são dextrorotatórios [α]D = +1,7 para o óleo de PG e [α]D = +4.4 para o óleo de PA). Trinta e dois e vinte e nove substâncias foram identificadas, representando 93.9% e 97.8% do total de óleo de PG e PA, respectivamente. Entre os trinta e dois constituintes identificados no oleo de PG, 93.6% são sesquiterpenos e β-Cariofileno(26.0 0.8%), globulol (9.3 0.2%), α-Cadinol (7.0 0.5%), α-Humuleno (6.4 0.1%) e Germacreno D (6.2 0.3%) são os constituintes químicos majoritário. No óleo de PA, cerca de 95,9% referem-se aos sesquiterpenos. Por outro lado, os constituintes principais foram Espatulenol (31.8 1.6%), α-cis-Bergamotene (8.8 0.2 %) e Viridiflorol (9.7 0.7%). Apesar do oleo essencial dessas especies serem constituídas basicamente por compostos da dos sesquiterpenos, eles são qualitativamente e quantitativamente diferentes. Os dados encontrados para essas duas espécies de Protium são comparados e discutidos com os reportados na literatura para outras amostras congêneres coletadas em outras regiões do Brasil e do mundo.

O objetivo do trabalho foi avaliar as mudanças que ocorrem no solo, na planta e na atmosfera imediatamente após a prática da queima do canavial. Para tanto, foram coletadas amostras de solo e da planta em duas situações (tratamentos) pré e pós-queima. As áreas foram padronizadas e referenciadas como talhões, cinco foram os talhões usados para cada tratamento (repetições). Para cada talhão foram realizadas cinco amostras. Estimou-se a emissão de CO2 utilizando as reduções de folhas, ponteiros e colmos proporcionadas pela queima, nos tratamentos. Todos os dados foram submetidos à análise de variância (ANOVA, p<0,05) com o teste de comparação de médias Scott-Knott (p<0,05) e estudados por análise multivariada por componentes principais (PCA). Com relação à comparação da pré e da pós-queima, as variáveis de biomassa (folhas, ponteiros, colmos) apresentaram diferenças estatísticas. Entretanto, as variáveis % de MS do ponteiro (%ponteiro) e brix corrigido não apresentaram diferenças quando comparadas a pré e a pós-queima. O resultado do cálculo da quantidade de CO2 emitida pela queima das folhas foi de 3,89 Mg ha-1 (toneladas por hectare) e devido à queima dos ponteiros mais 0,92 Mg ha-1 de CO2 foram lançadas na atmosfera, totalizando 4,81 Mg ha-1 de CO2 totais. Os dados referentes ao Mn, Cu e B apresentaram diferenças estatísticas de teores quando comparados antes e após a queima. Na análise multivariada houve uma divisão clara entre os dados da pré e pós-queima, influenciados pela biomassa vegetal. O trabalho concluiu que a queima da cana promove redução de folhas, ponteiros e colmos em 92,48%, 33,52% e 30,70% respectivamente. No solo ocorreu redução de manganês em 21,04%, de cobre em 19,32% e de boro em 30,56%. Na atmosfera ocorre emissão de 4,8 Mg ha-1 de CO2, provenientes da queima de 10,41 Mg de biomassa vegetal.

The objective of the work was to evaluate the changes that occur in the ground, the plant and the atmosphere immediately after the practical one of the burning of the canavial. For in such a way, it compared the effect of the burning of the sugarcane plantation in the ground and the proper sugar cane, thus, samples of these items in two situations had been collected show before (treatments) and after burning. The standardized areas had been referencing as pulley and had been repeated five times, for each pulley five samples had been carried through. All the data had been submitted to the analysis of variance (ANOVA, p<0,05) and to the test of comparison of Scott-Knott averages (p<0,05) and for the analysis multivaried for main components (PCA). In the multivaried analysis it had a clear division it enters the data of the daily pay and after-burns. The data show that before the burning only the variable leaves they had presented variations in the standardized pulley and that subsequent to burns these differences for leaves had disappeared. With regard to comparison of the one before and of after-it burns, the variable, Leaves, Hands, Stalk, Total and % Leaves had presented statistical differences. The…

Les fluides (gaz et liquides) existent partout autour de nous. Alors que l’eau recouvre 70% de la croûte terrestre, des couches de gaz comme l’azote et l’oxygène entoure notre planète. Le domaine de la dynamique des fluides comprend l’étude des liquides ou des gaz en mouvement. Les équations qui régissent le mouvement des fluides à savoir les équations de Navier-Stokes sont des équations aux dérivées partielles non-linéaires complexes qui n’ont pas de solutions analytiques pour la plupart des problèmes d’intérêt pratique. Cependant, en utilisant des schémas numériques, ces équations aux dérivées partielles de variables continues peuvent être transformées en d’énormes systèmes algébriques de variables discrètes et résolues à l’aide d’ordinateurs à haute-performance. Une méthode numérique résolue sur un dispositif informatique introduira des erreurs dans la solution finale, nécessitera une quantité donnée de ressources de calcul comme la mémoire et le processeur, et prendra une quantité finie de temps pour parvenir à une solution. Ainsi, le développement d’algorithmes plus précis et plus rapides pour résoudre numériquement les équations d’un système de dynamique des fluides est un domaine de recherche en évolution constante. Le présent document est dédié à la fois à l’étude des algorithmes numériques d’ordre peu élevé, ainsi qu’à la mise en œuvre de méthodes existantes ou le développement et la mise en œuvre de nouvelles méthodes d’ordre supérieur, pertinentes pour la résolution des équations de Navier–Stokes incompressibles. L’ensemble du travail a été effectué sur le solveur adaptatif Cartésien d’équations fluides Basilisk. Nous recherchons en particulier des solveurs pour la convection–diffusion, les équations de Poisson–Helmholtz, les schémas temporels et les équations de Saint-Venant. Nous examinons des méthodes de maillage adaptatif pour résoudre ces équations et prenons l’implémentation de Basilisk de l’algorithme adaptatif en ondelettes sur quad-octree comme point de départ pour construire un nouveau schéma adaptatif d’ordre supérieur. Un thème récurrent tout au long de cette thèse est la comparaison de la précision et des performances informatiques de différents schémas d’ordre supérieur par rapport à leurs homologues d’ordre inférieur.

Fluids (gases and liquids) exist everywhere around us. Water covers 70% of the Earth’s crust and gases like nitrogen and oxygen surround the planet. The field of fluid dynamics involves the study of liquids or gases in motion. The equations which govern the motion of fluids viz. The Navier–Stokes equations, are complex non-linear partial differential equations which do not have closed-form analytical solutions for most problems of practical interest. However, using numerical schemes, these partial differential equations of continuous variables can be transformed into huge algebraic systems of discrete variables and solved using high-performance computers. A numerical method solved on a computing device will introduce errors in the final solution, will require a given amount…

▼ The study of species’ geographic distributions, especially limits to those distributions, lies at a fruitful nexus of ecology and evolutionary biology. At these distributional limits, the ecological interactions that determine population mean fitness across and beyond the range limit collide with the evolutionary limits to adaptation. Species’ geographic distributions comprise the spatial extent of their populations, and vary greatly in size, shape, and the arrangement and abundance of populations contained therein. However variable these distributions are, they all are bounded by an invisible perimetric line on the landscape beyond which populations of that species cannot be found, i.e., the species’ geographic range limit. Why are individuals able to persist on one side of this border but are excluded from regions directly adjacent? This deceptively simple question is a perennial one that underlies many foundational questions about ecological interactions and adaptation. Distributions are structured by myriad factors with large, small, and interactive effects, but the essential determinants of the spatial patterns are relatively simple — populations persist where long term growth rates are equal to or greater than replacement (λ ≥ 1). But given sufficient time and adequate heritable variation for ecologically important traits, species’ ranges should theoretically be able to continually expand outward through sequential adaptation by populations at the range edge. Of course, this is not the observed pattern in nature; most species are restricted to a relatively small fraction of the planet’s available habitat. This dissertation is an attempt to untangle the complex environmental gradient that occurs across and beyond C. x. xantiana’s distribution, and evaluate the relative importance of precipitation, mammal herbivory, pollinator limitation, and biotic and abiotic edaphic factors in setting the subspecies’ geographic range margin. In Chapter 1, I focus on fatal mammal herbivory and evaluate its potential as a range limiting factor, with a conceptual approach based on foundational range limits theory. I show that probability of herbivory increases sharply near and beyond C. x. xantiana’s range margin, that this interaction has large effects on population mean fitness at the transplant site beyond the range edge, and that susceptibility to herbivory is largely mediated by plant phenology. In Chapter 2, I follow up on these results with a large field experiment at multiple sites inside and outside the range, estimating the effects of geography, source population, herbivory, and pollen limitation on lifetime fitness across two years. Protection from herbivory and supplementation of pollen increased plant fitness three to seven-fold outside the range margin, and there was only limited evidence of local adaptation of C. x. xantiana populations. Both of the transplant experiments reported in these chapters captured both a relatively wet and a relatively dry year, and showed that the effect of herbivory on population mean…

▼ The purpose of this work was to determine via simulations the potential use of sim- plified scattering point models in full-field breast Cone-Beam Computed Tomography (CBCT). A many Scattering Point (MSP) per incident beamlet model and a Single Scat- tering Point (SSP) model were tested against Geant4 simulations, as well as against each other. Comparisons were made using both homogeneous as well as heterogeneous phantoms. The homogeneous phantoms were cylinders, 14 cm and 7 cm in diameter and 10.5 cm in length with various fibroglandular(fib):fat compositions. The hetero- geneous phantom was the 14 cm phantom mentioned previously, but modeled as pure fib with a number of smaller embedded cylinders composed of fat. A second configu- ration with the compositions of the main and embedded cylinders swapped was also tested. The simulation used a 60 kV tungsten anode spectrum with a HVL of 3.7 mm Al which irradiated the simulated breast phantom over 300 projections. The detector was modeled as 300 × 300, 1 mm2 energy integrating pixels, with a DQE of unity. Both of the models approximate the cone-beam as a number of individual beamlets (300 × 300 to match with the detector) with scattering points placed along their in- tersections with the phantom. The MSP model incorporated a single scattering point per 1 cm of incident beamlet length within the phantom. The SSP model used an adjustable single scattering point positioned at a fractional depth within the phan- tom. By comparing results from these two scattering point models, values of were determined which would yield SSP model scatter approximations matching those of iii the MSP model. Both models were tested against Geant4 simulations for their ability to adequately estimate the scatter signals upon the detector. The SSP model was also tested for its ability to correct for the cupping artifact in reconstructed images of the heterogeneous phantom, without assuming knowledge of the inner heterogeneous geometry. The Hounsfield Units (HU) obtained with primary photons were 48.5±3.18 and −159 ± 23.0 for fib and fat respectively for one of the heterogeneous phantom con- figurations. Due to the cupping artifact in the reconstructed images which included scatter, these values were −46.6 ± 18.9 and −215 ± 34.0 respectively. Following cor- rections for the single scatter, via the SSP model, the corresponding CT numbers became 52.3 ± 3.67 and −161 ± 23.3. It was encouraging to see that a simple model can minimize the effects of single scattered photons during CBCT of a heterogeneous phantom. The HUs obtained post-scatter correction agreed well with those obtained with primary photons. The preliminary findings encourage further efforts for thoroughly testing these scatter point models’ applicability for obtaining higher quality CBCT images.

▼ Plant roots form symbioses with various fungi, including arbuscular mycorrhizae (AMFs) and dark septate endophytes (DSEs). The symbiosis between plants and AMFs has been extensively studied and is generally considered to be mutualistic. Much less is known about the symbiosis between plants and DSE. In sagebrush habitats, DSEs are common, but their effects on the vegetation are unclear. As a first step to study these effects, I isolated and cultured a DSE from the roots of the shrub Artemisia tridentata. Based on partial sequences of five genes and phylogenetic analyses, the isolated fungus was a non-described species within the Darksidea or a closely related sister group. Subsequently, I performed experiments in vitro and in potted plants to determine the effect of the isolated DSE on root tissue integrity, colonization by the AMF Rhizophagus irregularis, and plant biomass. These experiments were conducted in two plant species, A. tridentata and the native grass Poa secunda. Plants were exposed to one of four treatments: no inoculation (-AMF-DSE), inoculation with the DSE isolate (-AMF+DSE), inoculation with R. irregularis (+AMF-DSE), and inoculation with both fungi (+AMF+DSE). Microscopic observations revealed that the DSE hyphae grew along the root surface and penetrated epidermal and cortical cells without damage to them. In A. tridentata, the hyphae also reached the stele. For both species, total DSE colonization in the –AMF+DSE treatment was similar to that in the +AMF+DSE treatment, indicating the presence of AMF did not alter DSE colonization. Inoculation with DSE did not affect total AMF colonization of A. tridentata; however, it increased total colonization of P. secunda from 16.9 (+5.6%) in the +AMF-DSE treatment to 42.6 (+2.9%) in the +AMF+DSE treatment. Also, in both species, the presence of the DSE more than doubled the frequency of AMF intraradical storage structures, which consisted of vesicles plus intraradical spores. These results suggest that via increases in AMF colonization, DSE could lead to a beneficial effect on the host plants. However, neither on its own nor through co-inoculation with AMF, did the DSE isolate affect plant biomass. Thus, under the two conditions tested, the symbiosis was commensalistic. Further work is needed to evaluate the symbiosis in settings that better mimic the natural environment.
