L'objet de cette recherche consiste à capturer et analyser les relations entre l'architecture et les technologies récentes sous l'angle de la perception. Loin de la subjectivité supposée, l‘analyse guidée par la notion d'expérience perceptive s'appuie à la fois sur des concepts esthétiques et phénoménologiques. Cette double réflexivité porte également sur une étude de cas conceptuels et « concrets » qui opèrent la vision de la spatialité architecturale dans des tensions spéculatives entre le monde « numérique » et physique. La problématique porte sur la réception de l'architecture comme valeur culturelle et production intellectuelle, coordonnée par des moyens technologiques qui l'amplifient. S'inscrivant dans l'hypothèse qu'aujourd'hui l'architecture est loin de « servir » uniquement de réponse aux questions formelles, structurelles et fonctionnelles, la recherche démontre que l'architecture s'approche de plus en plus du champ artistique en phase d'expérimentations permanentes. Analysant les facteurs d'esthétisation de concepts variés, l'étude des cas vise à appréhender l'aspect cognitif et la valeur esthétique de la réception technologique — notion nouvelle, introduite comme un outil opératoire permettant d'aborder les aspects sensibles, hybrides et variables de la production architecturale. L'originalité de cette recherche consiste donc à analyser les connexions instables qui caractérisent les processus actuels de transitions diverses dans le domaine de l'architecture. À ce titre, cette recherche propose d'ouvrir le champ de la discussion autour du « digital » selon les principes de la singularité architecturale dans la pluralité des réceptions possibles

The purpose of this research is to capture and analyze the relationships between architecture and recent technologies in terms of perception. Far from the supposed subjectivity, this analysis guided by the notion of perceptual experience, is based on both phenomenological and aesthetic concepts. This double reflexivity also relates to the conceptual and "concrete" case studies operating the architectural vision of spatiality in speculative tensions between the "digital" and the physical word. The problematic concerns the reception of architecture as a cultural value and intellectual production, coordinated by technological means that amplify it. In keeping with the assumption that today's architecture is far away to "serve" only as a response to formal, structural and functional questions, this research shows that architecture is increasingly approaching the artistic field in phase of permanent experimentations. By analyzing the factors of aestheticization of various concepts, case study seeks to understand the cognitive and the aesthetic value of the technological reception — new notion, introduced as an operational concept to approach the sensitive, hybrid and variables issues of architectural production. The originality of this research consist of analyzing the unstable connections that characterize the current processes of various transitions in the field of…

▼ The present study evaluated the in vivo hepatoprotective activity of two medicinal plants, namely, Satureja punctata Benth. Briq. (Lamiaceae) and Solanecio angulatus Vahl Jeffrey (Asteraceae) used in Ethiopian traditional medical practices for the treatment of liver diseases. The levels of hepatic marker enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were used to assess their hepatoprotective activity against ferric nitrilotriacetate (FeNTA)-induced hepatotoxicity in Sprague Dawely rats. The results revealed that pretreating rats with the crude aqueous extract of S. punctata at a dose of 500 mg/kg significantly suppressed the plasma AST (P < 0.01); ALT (P < 0.01) and ALP (P<0.001) activity when compared with control, while S. angulatus at a dose of 200 mg/kg reduced the activity of AST (P<0.01) and ALP (P<0.01) but failed to significantly suppress ALT activity. Among the soxhlet fractions of S. punctata, the methanol fraction at a dose of 500 mg/kg showed maximum hepatoprotective activity (P<0.001). The chloroform fraction at a dose of 250 mg/kg showed significant reduction in AST, ALT and ALP (P<0.01) activity while the aqueous fraction at a dose of 250 mg/kg showed significant reduction in AST (P<0.001), ALT (P<0.001) and ALP (P<0.05). Histopathological studies also supported these results. In vitro DPPH assay conducted on the soxhlet methanolic fraction of S. punctata showed that it possessed significant free radical scavenging activity which led to the conclusion that the hepatoprotective activity of the plant could be at least in part through its antioxidant action. The extracts showed good toxicity profile in acute toxicity study. Phytochemical analysis of S. punctata showed the presence of flavonoids, polyphenols, alkaloids and tannins. These results suggest that the aerial part of S. punctata contains bioactive principles with hepatoprotective activity. Advisors/Committee Members: Ephrem Engidawork (PhD) (advisor).

▼ Due to their low cost and desirable properties, many recent efforts in the field of semiconductor research have been devoted to the discovery and investigation of organic materials. Within this field, thiophene-based materials make up a large portion of the abundant p-type semiconductors seen in research and commercial devices. All the while, the options for n-type materials are limited due to the restrictive constraints placed on their electronic properties in order to be air stable. Thiophene-S,S-dioxide-based materials have the potential to be strong contenders with n-type materials currently available. However, they are currently difficult to obtain synthetically, in large part due to the loss of aromaticity that occurs upon oxidation of the thiophene moiety. Typically, long reaction times, and/or harsh reaction conditions, or highly toxic, unstable reagents are required. Herein, two potential synthetic routes to thiophene-S,S-dioxides are described. The first aimed to take advantage of hydrogen bonding interactions to direct the oxidation of the thiophene, and then use the same directing group as a handle for ipso-arylative cross-coupling. This approach would ultimately reduce the need for harsh conditions, and minimize the number of steps required to produce thiophene-S,S-dioxide-based materials. The second route looked to be the first synthesis of a thiophene-S,S-dioxide that does not involve the oxidation of a thiophene or thiophene-S-oxide, by performing a formal [2+2+1] between two alkynes and sulfur dioxide, provided by an SO2 surrogate. While the first method was able to produce the desired thiophene-S,S-dioxide, the oxidation does not seem to be promoted by the intended directing group, and the thiophene-S,S-dioxides involved have been observed to be unstable to the ipso-arylation conditions. Reaction conditions investigated for the second route do not appear to yield the desired thiophene-S,S-dioxides, but have produced other materials for which structural elucidation and characterization is ongoing.

▼ Iron sulfur (Fe-S) clusters are essential cofactors that function in electron transport, catalyzing substrate turnover, environmental sensing, and initiating radical chemistry. Elaborate multi-component systems have evolved to protect organisms from the toxic effects of free iron and sulfide ions while promoting the efficient biosynthesis of these cofactors. The in vivo loss of frataxin (FXN) function results in depleted activity of Fe-S enzymes and is directly linked to the fatal and incurable neurodegenerative disease Friedreich’s ataxia (FRDA). Previously, our lab discovered the cysteine desulfurase and Fe-S assembly activities of the human Fe-S assembly complex (SDU), which consists of the cysteine desulfurase complex NFS1-ISD11 and scaffold protein ISCU2, are greatly stimulated by FXN binding and forming the SDUF complex. This dissertation’s objectives were to identify critical FXN interactions for binding and activation of the SDU complex, investigate the interprotein sulfur transfer reaction between NFS1 and ISCU2, and provide mechanistic details of Fe-S assembly on the SDUF complex. First, surface residues on FXN were substituted with alanine or glycine and the ability of each variant to bind and activate the SDU complex was assessed. These experiments revealed a localized “hotspot” of critical residues on FXN, which could aid in designing small peptide mimics for FRDA therapeutics. Second, ^(35)S-radiolabeling experiments indicated FXN accelerates the accumulation of persulfide species on NFS1 and ISCU2. The ISCU2 persulfide species was established as a viable intermediate in Fe-S cluster biosynthesis by tracking the ^(35)S-radiolabel as it converts from a persulfide species to a [2Fe-2S] cluster. Additional mutagenic, enzymatic, and spectroscopic studies suggest conserved ISCU2 residue C104 is critical for FXN-based activation, whereas C35, C61, and C104, are all essential for Fe-S cluster biosynthesis. These results lead to an activation model in which FXN facilitates sulfur transfer from NFS1 to ISCU2 as an initial step in Fe-S cluster biosynthesis and favors helix-to-coil interconversion on ISCU2. Third, UV-visible, circular dichroism, and Mössbauer spectroscopic studies indicated the SDUF complex synthesizes transient [2Fe-2S] clusters that readily transfer to thiol-containing acceptor molecules. Moreover, these studies revealed competing DTT-mediated transfer and mineralization chemistry that cause complications when studying the mechanism of Fe-S cluster biosynthesis.

The forage species of Stylosanthes and its adaptation to different environments have increased demand on the seed trade, which requires accurate information for your use. For the study of seeds conservation is necessary prior knowledge of physiological characteristics and their environmental requirements. The goal this work were establish appropriate conditions of temperature and substrate in germination tests and evaluate the germination of seeds of S. capitata, S. scabra and S. viscosa subjected to different times and storage environments to conservation. The tests were performed in the laboratory of Germination at Universidade Estadual de Feira de Santana-UEFS, Feira de Santana-BA. The temperature tested were: 25, 30 and 20-30 ?C and the substrates were on paper (P), roll paper (RP) and commercial Biomix. To evaluate the behavior in conservation, Stylosanthes seeds were stored for 12 months at room temperature (lab), refrigerator, in freezer and in liquid nitrogen. The species S. capitata, S. scabra and S. viscosa showed variability regarding germination. The seeds germination of S. capitata was improved at on paper and temperatures 30 ?C constant and 20-30 ?C alternating. For S. scabra and S. viscosa seeds were recommended the roll paper at room temperature (25 ?C). Seeds of Stylosanthes respond differently to the conditions of storage and germination tests. S. capitata seeds seem to be more tolerant of the storage conditions, remaining vigorous for 12 months. Besides the physical dormancy, seeds of the S. scabra e S. viscosa it seems put forward the physiological dormancy and the maintenance of seeds in controlled laboratory conditions increased the ability of germination, but with reduced vigor.

▼ Penggunaan baja kimia dalam pertanian boleh mencemarkan produk pertanian, tanah dan alam sekitar. Kesannya tanah akan menjadi asidik, padat, kehilangan keupayaan pegang air dan proses larut lesap nutrien. Dalam kajian ini baja Organoseep telah digunakan sebagai produk pengganti kepada baja kimia. Baja Organoseep dibuat daripada penapaian gabungan tumbuhan, haiwan dan mineral (penggalak baja) dengan menggunakan teknologi mikroorganisma efektif generasi baru yang diproses khas menggunakan formula baru. Ini merupakan kaedah baru dalam pengeluaran baja organik bagi menghasilkan produk pertanian hijau dan melindungi kelestarian alam sekitar. Objektif penyelidikan ini ialah mengkaji keberkesanan baja Organoseep terhadap pokok tomato (Solanum lycopersicum) terhadap tumbesaran pokok, pengeluaran bunga, hasil tuai perubahan pH media tanaman, lebar daun, dan kadar kematian. Perbandingan keseluruhan kos penanaman menggunakan empat jenis baja iaitu Organoseep, Organik, Biokimia dan Kimia. Kajian ini dijalankan di ladang fertigasi TS Agro Resort iaitu penanaman pokok tomato menggunakan sistem fertigasi dalam struktur perlindungan tanaman (SPT). Media penanaman adalah sabut kelapa. Pembajaan dilakukan setiap minggu selama 10 minggu, 100g bagi perlakuan Organoseep, Organik dan Biokimia dan 50g bagi baja kimia. Cerapan kematian adalah setiap hari, pengukuran ketinggian, lebar daun dan pH media tanaman diukur setiap seminggu sekali. Hasil tuai dan bilangan bunga dicerap dua kali seminggu. Dapatan kajian menunjukkan bacaan pH media penanaman baja Kimia dan Biokimia telah mengalami kadar penurunan ke arah asidik. Organoseep dan Organik, ke arah neutral atau sedikit alkali. Ke semua perlakuan adalah signifikan (p>0.05) terhadap tumbesaran dan kelebaran daun tetapi signifikan (p<0.05) terhadap bilangan bunga dan hasil tuai. Organoseep, Biokimia dan Kimia mengalami satu kes kematian daripada 90 sampel (0.01%). Manakala Organik tiada kematian dicatatkan. Keputusan tertinggi jumlah berat hasil tuai terkumpul bagi 90 pokok tomato ialah baja Kimia 40.40kb, diikuti Biokimia 36.85kg, Organoseep 36.45kg dan Organik 28.45kg. Hasil jualan kesemua perlakuan telah mendapat keuntungan selepas ditolak kos tetapi Nisbah Keuntungan Terhadap Kos Baja tertinggi adalah Organoseep 10.5411 unit, Kimia 9.1128 unit, Biokimia 7.6855 unit dan Organik 4.9623 unit. Kesimpulannya, kajian ini menunjukkan baja Organoseep sangat berpotensi menggantikan baja Kimia.

Biologija - Ekologija, biogeografija i zaštita životne sredine / Biology - Ecology, biogeography and environmental protection

Vrste roda Sesleria (Seslerieae, Pooideae, Poaceae) su rasprostranjenje u većem delu Evrope, a javljaju se marginalno i u severnoj Africi (Maroko, Libija) i zapadnoj Aziji (Kavkaz). Rod obuhvata oko 40 taksona u rangu vrsta i podvrsta, rasprostranjenih na području Balkanskog poluostrva, Karpata i Alpa. Pretpostavlja se da je rod nastao u Alpima, ali je centar morfološkog i taksonomskog diverziteta na području Balkanskog poluostrva. Kako morfološki i anatomski karakteri po pravilu postepeno variraju, nije bilo lako ustanoviti kvalitativne razlike koje bi imale veći taksonomski značaj, što je dovelo do pogrešnih taksonomskih klasifikacija roda Sesleria. U skladu sa tim, evolutivna istorija, morfološka varijabilnost, rasprostranjenje i ekološke karakteristike pojedinih vrsta roda Sesleria su još uvek slabo poznati. Istraživani kompleks Sesleria rigida je rasprostranjen u Rumuniji, Bugarskoj, Srbiji, Bosni i Hercegovini i Grčkoj, a prostire se duž nekoliko planinskih venaca Balkanskog poluostrva – centralni i istočni delovi Dinarskih planina, Karpato–Balkanidi (istočni i južni Karpati, planine u severoistočnoj i istočnoj Srbiji, zapadnoj i centralnoj Bugarskoj), Rodopske planine u Bugarskoj i jugoistočnoj Srbiji i Grčkoj. Vrste ovog kompleksa su zabeležene u širokom dijapazonu nadmoskih visina (od 70 mnv do 2400 mnv), naseljavaju staništa pretežno na karbonatima, ali se mogu javiti i na serpentinitima. S obzirom na različitost stavova po pitanju taksonomije kompleksa i njegovu nedovoljnu morfološku, genetičku, fitogeografsku i ekološku istraženost,osnovni ciljevi ovog rada su: utvrñivanje areala pojedinačnih taksona, utvrñivanje osnovnih karakteristika njihovih staništa i samim tim i njihove ekološke preferencije, opisivanje varijabilnosti morfo-anatomskih karaktera, kao i genetičke varijabilnosti populacija primenom molekularnih metoda. Konačan cilj ovog rada predstavljala bi taksonomska revizija čitavog kompleksa. Areali pojedinačnih taksona su kartirani na osnovu podataka iz literature, kao i na osnovu revizija herbarskog materijala i terenskih istraživanja. Podaci o ekologiji vrsta su prikupljeni obradom literaturnih podataka, a vegetacijske grupe koje odgovaraju tipovima staništa na kojima se javljaju analizirani taksoni su utvrñene klaster i ordinacionim analizama. Varijabilnost morfoanatomskih karaktera je utvrñena na osnovu merenja 42 morfo-anatomska karaktera...

▼ In the field crops are subject to a wide variety of biotic and abiotic stresses. In order to manage crop protection effectively it is important that we understand not only the way plants respond to these stresses, but the way in which these responses interact. High levels of fertilisers and pesticides are often applied to maintain soil nutritional status and prevent disease in modern intensive farming systems. Potassium (K) is an essential element for plant growth and development, and is required for a wide variety of processes within the plant. These processes can be broadly divided into biophysical processes such as stomatal opening and cell extension and biochemical processes such as protein synthesis and enzyme activation. K starvation has been shown to lead to increased levels of the stress hormone jasmonate (JA) and related compounds in Arabidopsis thaliana plants which in turn modulates the plant’s defence against herbivorous insects and probably other pests or pathogens (Armengaud et al., 2004; Troufflard et al., 2010). In order for these results to be applicable to agriculture it is important to assess whether crop plants respond to K in a similar manner as the model plant. In this project the effect of K-deficiency on growth, metabolite concentrations, transcript levels and pathogen susceptibility of barley were investigated. Plants were grown in full-nutrient (control) or K-free hydroponic culture. The physiological, biochemical and transcriptional effects of K-deprivation were accessed over a time course of 20 days. Roots and shoots from plants grown in K-free nutrient solution had significantly lower K concentration than those grown in the control solution after 3 and 6 days respectively. A significant reduction in growth was seen as early as 6 days after K withdrawal. K-starvation led to a slight decrease in nitrogen metabolism, while hexose sugars strongly accumulated. By day 9 a significant increase in the expression of JA marker genes was seen in plants grown in K-free nutrient solution. Thus, despite possible differences in downstream events an induction of JA biosynthesis in response to K-deficiency occurs in both Arabidopsis and barley. Detached leaf segments were used to assess the effect of K-deficiency on infection of barley by two fungal pathogens with different strategies for nutrient acquisition. K-deficient barley plants were less susceptible to the biotroph Blumeria graminis f. f. sp. hordei (powdery mildew) and more susceptible to the hemi-biotroph Rhynchosporium secalis. Treatment of detached leaves with methyl-jasmonate (Me-JA) also led to less B. graminis infection, but had no effect on the R. secalis infection, indicating that JA increase in response to K-deficiency influences B. graminis but not R. secalis infection. The study therefore provides strong evidence that the effect of K-deficiency on pathogen susceptibility is determined by the JA-sensitivity of the pathogen.

▼ Dietary factors contribute to ammonia emission and amount of nitrogen in the excreta. The excretion of nitrogen originating from dietary protein is largely responsible for some of the environmental issues associated with poultry production. Protein is essential as the very building block of the animal itself and hence protein nutrition takes a centre stage in poultry feeding. The use of dietary crude protein with crystalline amino acids as a means to decrease the impact on the environment of intensive poultry production is consequently of importance. Two experiments were carried out to investigate the effect of dietary manipulation using four different concentration of protein with and without amino acid supplementation on turkey performance, litter quality and nutrient utilization. The birds were raised in an environmentally controlled house and lighting procedure followed was the recommendation for the turkey breed. In the first study, the aim was to investigate the effect of dietary manipulation using four different concentrations of crude protein. One-hundred and twenty 7-day old BUT 10 turkeys were allocated to 4 treatments in a randomised complete block design. Each treatment had 6 replicate pens with 5 birds per replicate pen. The treatments were a diet adequate in protein and amino acids (diet 1) according to the breed specification and three other diets (diets 2, 3 and 4) formulated to have stepwise reduction of at least 1.4% protein from the previous diet such that the last diet had approximately 4% lower protein level than the first diet. The diets were fed in four phases of four weeks each (except the first phase that lasted 3 weeks). The highest protein levels were 28.8, 25.9, 21.7, and 18.5% and the lowest protein levels were 24.5, 21.0, 18.2 and 15.0%, respectively for phases 1, 2, 3 and 4. The diets were supplemented with appropriate crystalline amino acids that were present in the diet at lower than the requirement for the specific phase in each of the diets. The diets were formulated on digestible amino acid basis. Growth performance data were collected at the end of each phase. Overall there were no significant effects of diet on daily weight gain, feed intake or gain: feed. The final body weight was not influenced by the dietary treatments. The data from this experiment showed that supplementing a low-protein diet with crystalline amino acid produced weight gain similar to that of birds receiving adequate intact protein in their diets and support a superior efficiency of protein utilisation for weight gain. The second study was designed to investigate the nutrient utilisation response of turkey to reducing the dietary protein supply by soybean meal and supplementing with amino acids. A total of 96 seven-day old male turkeys (B.U.T.10) were used for the study. On day 7, the birds were allocated to four dietary treatments in a randomized complete block design using initial body weight as the blocking criterion to ensure equal body weight in all the treatments at the start of the…

▼ In recent years, Conservation Agriculture (CA) has been promoted in sub-Saharan Africa (SSA) as an alternative farming system for smallholder farmers to address declining soil productivity and climate change. CA is a technology package based on 1) minimum soil disturbance; 2) permanent soil cover; and 3) maximum crop diversity through rotation/association. Claims about the potential benefits of CA for smallholder farmers in SSA are contested, and the (non-)adoption by farmers remains difficult to predict and understand. This research combines different conceptual models to better understand the adoption and promotion of CA in Kenya and Madagascar with a wider relevance for similar practices in SSA. For both countries, the major stakeholders in the innovation systems and their interlinkages are described, with a focus on the position of smallholder farmers. Stakeholders' 'theories of change', narratives and 'framing' of the importance of CA, and their perceived legitimation for their involvement in CA, are described. Results show that the Agricultural Innovation Systems (AIS) approach through Innovation Platforms remains difficult to translate into practice; expert-based development approaches remain the norm. It is argued that this is partly the result of an institutionalisation of purposive-rational policy and practice, while the capabilities approach and Habermas' theory of communicative action explored in this thesis, suggest the need for a counter institutionalisation of more communicative-rational thinking and practice. Communicative action can enable an AIS approach that actually provides sustainable technological and institutional innovation. This research shows that the social-psychological Reasoned Action Approach is a useful heuristic for understanding farmers' intention to adopt CA practices in terms of attitudes, perceived social norms and perceived behavioural control (PBC), and the respective underlying beliefs. Results show that attitudes and PBC are the main determinants of intentions. It is recommended to promote experimentation and learning, because these influence both PBC and attitudes.

▼ Many species of moths within the family Noctuidae are significant agricultural pests. Specific floral volatiles are attractive to both male and female Noctuidae and may be used to as attractants in crop protection. For the first time the following research compares two types of floral volatile blends - those that mimic natural floral odours and those that are artifical odour blends ('super-blends'). In wind tunnel bioassays and field trials in two diverse geographic locations (Argentina and the United Kingdom) a range of noctuid moth species that are considered crop pests were found to be attracted to both types of the floral odour blends. However, a 'super-blend' containing phenylacetaldehyde, salicylaldehyde, methyl 2-methoxybenzoate, linalool, and limonene (in a 10 : 4 : 2 : 2 : 1 ratio) was found to be the most effective general attractant across the following species: Helicoverpa armigera and gelotopoeon, Heliothis zea, Spodoptera frugiperda, and Autographa gamma suggesting that these compounds are universal cues to this family of moths when searching for flowers. Further behavioural bioassays found that the physiological state of the insect had an important effect on its behavioural response to the floral odour super-blend. Bioassays carried out on H. armigera revealed that gravid insects were significantly less likely compared to virgin insects to make contact with an odour blend baited lure. In addition, insects provided with sucrose solution were significantly less likely to make contact with the odour source compared to starved insects or insects only provided with water. This is the first time this affect has been seen in this species and may have important implications for using these types of floral odours for crop protection. Investigations into the most effective trap for capturing Noctuidae found that a homemade bucket and water trap or funnel and sleeve traps were significantly more effective than UniTraps or sticky traps. During the field trials large numbers of nontarget insects were also captured, including beneficial insects and pest species. By using green coloured traps captures of beneficial hymenoptera (Syrphidae and Apoidea) were significantly reduced. Taken together, the current findings provide insights into how Noctuid moths interact with host odour cues and how they may be used in developing pest management techniques.

▼ The Food and Agriculture Organization have emphasised the importance of farm animal genetic diversity for the assurance of future global food security. Modern pig production has concentrated on a small number of commercialised breeds. This has significantly contributed to genetic erosion and loss of native breeds, deemed productively inefficient. It has been recommended to conserve the unique traits of traditional breeds as genetic insurance against future challenges. In order to ascertain the commercial viability of traditional breeds, genetic and productivity analyses were completed, using the Large White (LW) and Landrace (LR) as the commercial comparison. Genetic diversity was assessed using a D-loop fragment of mitochondrial DNA for comparison between three purebred traditional breeds: Gloucester Old Spot (GOS), British Lop (BL) and Welsh (W), and commercial LW x LR. The traditional breeds greatly differed from the commercial hybrid, and possessed high variability at this genetic region. The BL and W demonstrated the greatest potential for crossbreeding to increase the diversity of commercial populations. The crossing of LW x LR dams with GOS, BL and W terminal sires produced traditional crossbreds for comparison with LW sired crossbreds. Nuclear DNA diversity was assessed using a region of the iodothyronine deiodinase type 3 (DIO3) gene. This demonstrated that crossbreeding could improve future productivity, by utilising traditional variation to maximise heterozygosity in the progeny. The productivity assessment established that the traditional and commercial crossbreds performed comparably for most of the growth variables measured, however there were highly significant differences for birth weight, weaning weight, back fat and production length. The traditional crossbreds have shown potential for future application, with the W most suited for commercial production, due to the equivalence with the LW. To conclude, the crossbreeding of traditional and commercial pig breeds is a viable genetic management strategy to conserve and genetically improve both groups.

▼ Considerable research has been carried out on organic soils which consist of various components of organic matter but the effect of particular organic matter is less reported. This may cause some of the contributing factors of each organic matter are not well understood because each type of organic matter have its own characteristic and the effect on the properties of soils is different. Hence, understanding the physico-chemical characteristic of organic soils is the fundamental needs for researcher and important to identify suitable method for further experiment. Artificial soil was used in this study to control the inconsistency of test results which may be obtained due to complexity of characteristics of natural organic soils. The main objective of this study to determine the effect of humified and non-humified organic matter of the soil samples on the physico-chemical and mineralogy, as well as the shear strength. Two types of artificial soils were utilized, namely kaolin mixed with compost (KC) and kaolin mixed with LM Bio Humus Juice (KH). Physical and chemical properties such as Atterberg limit, moisture content, specific gravity and acidity level were determined to establish the basic characteristics of soil. Mineralogy and molecular characteristic of samples were determined based on the XRay Fluorescence (XRF), X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). Strength of artificial soil was evaluated using unconfined compressive strength test (UCS). Based on the results obtained, compost had changed with decomposition in which it had degraded from fibric peat to hemic peat after a period of 6 months. Decomposition process also affected the physical and chemical properties of artificial soil. Specific gravity of artificial soil KC had reduced with the increment of decomposition period. Humified organic content of compost was found to be increased with decomposition period which shown that the fibres were decomposed. Fiber content had significantly decreased with decomposition period as well as its losses on Ignition (LOI). The strength of soil specimens KC were increased with decomposition period in which the humified matter were increased from 38% to 41% within the test period. The effect of humified matter on strength was tested utilizing artificial soil KH. The plasticity index of artificial soil KH decreased with increment of LM Bio Humus Juice which can be associated with flocculation of soil aggregate. Unconfined compressive strength of artificial soil KH had increased with higher content of LM Bio Humus Juice. The results obtained throughout this study will be beneficial for the understanding on the basic characteristic of organic soil as reference for further experiment in order to identify the strength and improvement method in real construction environment.

▼ The fly Drosophila suzukii is an invasive pest responsible for major economic losses in fruit industries. Females lay eggs through a punctured hole in the skin of ripening fruits which otherwise would be available for retail. Since 2010 the fly is included in the World Invasive Species Compendium, developed by CAB international (CABI) and on the Pest Alert List of the European Plant Protection Organization (EPPO) as an invasive agricultural pest threatening fruit production. Intensive research has been carried out to improve current management methods and develop Integrated Pest Management (IPM) techniques. One of the challenges is to develop species specific tools which require fundamental research on species-specific host selection processes. D. suzukii is also valuable to study host selection and the mechanisms of host detection in a polyphagous pest insect. It has a fascinating ecology and its close relatedness to one of the most intensively studied biological research models Drosophila melanogaster facilitates its study. Using a highly sensitive sensory system, females detect and select host plants to lay eggs in the ripening fruits. Semiochemicals released by these fruits may be used to lure them to traps or disrupt host detection. The aim of the research presented in this thesis was to determine how host fruit odours are encoded by the peripheral olfactory system in D. suzukii to enable host fruit detection and discrimination. The results provide a model of olfactory detection of hosts for polyphagous insects. The key result is that the peripheral olfactory system encodes ripe fruit odours via combinations of only a few classes of olfactory receptor neurons (ORNs). The combinatorial activation of the fruit specific ORNs guides host selection behaviour and enables the flies to discriminate among oviposition substrates. This model offers a novel approach for identifying semiochemicals to use in pest management. It enables a rapid screen of chemicals for potential attraction to oviposition sites by determining if the responses they elicit are part of the fruitprint: the pattern of neuron activity induced by host-fruit odours in the peripheral olfactory system.
