▼ Cotton (Gossypium hirsutum L.) crops usually experience some type of environmental stress during the season. Soil moisture deficits along with high temperatures pose the biggest constraints for crop productivity. Although usually hard to distinguish between drought and high temperature stress effects, it is important to develop means to help mitigate the negative impacts of such stresses on crop productivity. The 1-methylcyclopropene (1-MCP) is an ethylene antagonist that acts by binding to ethylene receptors, thus delaying and/or diminishing its effects on plants. Recently 1-MCP became the focus of several studies due to its potential to mitigate negative impacts of abiotic stresses. The main objective of this research was to assess the impact of 1-MCP on field grown cotton. The secondary objective was to investigate the association of canopy temperature (CT), canopy temperature depression (CTD), stress degree day (SDD), thermal stress index (TSI), and crop water stress index (CWSI) with crop yield. Field studies were conducted at the Texas A&M University Field Laboratory in Burleson County, TX from 2012 to 2014. Plots were arranged in a randomized complete block design and replicated four times. Treatments consisted of 1-MCP application (25 g a.i. ha^-1) triggered by canopy temperature (28 °C) and forecasted ambient temperatures (35 and 27.8 °C). For the secondary objective treatments were two irrigation levels, namely, dryland and irrigated. Results indicated that 1-MCP had little to no effect on the physiology and morphology of cotton at different stages of crop development. Daily plant canopy temperature, net photosynthesis, transpiration, and photosystem II quantum yield were affected by 1-MCP treatment when plants were irrigated, but not under dryland conditions. Effects of 1-MCP applications during different seasons were inconsistent. Ultimately, 1-MCP treatment effects were not enough to increase final seedcotton yield under the conditions tested. Negative relationships between yield and CT (r² = 0.66), yield and TSI (r² = 0.70), and yield and CWSI (r² = 0.58) were found. CTD and SDD showed great distinction between the humid (2012 and 2014) and dry (2013) years, and to a lesser extent, this was also apparent for CWSI. Evidence suggests that CTD, SDD, and CWSI models should be interpreted with caution, particularly in locations where great inter-annual weather variability occurs.

▼ Exertional Heat Illness (EHI) is a deadly but preventable disease. Interscholastic football players are particularly at risk for EHI, but there are no evidence-based guidelines for safety and acclimatization to prevent morbidity and mortality. Thus, the purpose of this study was: to investigate the effect the new Georgia High School Association (GHSA) pre-season acclimatization policy implementation had on the total and significant (heat stroke/heat exhaustion (HS/HE)) injury rates (IR), over the entire season and first two weeks of data ; to determine if IR’s by WBGT ranges during the first two weeks of data collection were significantly different in the time period before the policy change (Seasons 2009-11, PRE) when compared to those following change (2012 season, POST); and to determine the effectiveness of current heat stress index scales (HSIS) and which mitigate risk for EHI events. There were a total of 761 EHI cases and 259,413 Athlete Exposures (AE) for an overall EHI rate of 2.93/1000 AE (95%CI=2.73, 3.15). Risk for HS/HE was approximately 4 times greater for the entire data collection period (annual) for PRE [0.82/1000AE (95%CI=0.70, 0.95)] compared to the POST period, 0.22/1000 AE (0.12, 0.37)) and 7 times greater for the first two weeks of participation for the PRE period [1.85/1000AE; (95%CI=1.54, 2.21)] compared to the POST period at 0.27/1000 AE (95%CI=0.09, 0.65)). The EHI risk was lower in the POST period than in the PRE period for the entire data collection period [2.24/1000AE (95%CI=1.88, 2.65)] and 3.14/1000 AE (95%CI=2.90, 3.39, respectively) and first 2 weeks of data collection [1.22/1000AE (95%CI=0.75, 1.89] and 4.48/1000 AE (95%CI=3.98, 5.02), respectively). The Pearson correlation showed an r of 0.963 and an r2 value of 0.927 between WBGT and Discomfort Index (DI). The majority of the HSIS’s appeared to capture risk well. This study demonstrated mitigation in EHI risk following the policy change and that existing HSIS’s seem to adequately stratify risk.

▼ Athletic trainers must consider environmental conditions when making decisions concerning football practices. Those working in southern settings are faced with stressful environmental conditions often associated with the late summer and early fall. Strategies to minimize heat stress include proper acclimatization, hydration, conditioning, heat illness recognition, and weather monitoring. The purpose of this study was to evaluate the rate of exertional heat illness (EHI) in athletes during a three month period (August-October) at five southeastern universities. The Heat Stroke Checker (KEM Kyoto Electronics Manufacturing Ltd; Japan) was used to measure environmental conditions three times a day at each location. The American College of Sports Medicine (ACSM) and Department of Defense (DOD) Wet Bulb Globe Temperature (WBGT) Heat Stress Index Charts were used to identify the levels of heat illness risk. Heat cramps, heat syncope, heat exhaustion, heat stroke, and hyponatremia were evaluated based on the NATA Exertional Heat Illness position statement. A reportable injury was any athlete who incurred a heat related illness evaluated by the medical staff. A total of 139 heat-illnesses were reported with an EHI rate of 4.19/1000 athlete-exposures (AE) during the three-month period. No cases of heat stroke or hyponatremia were reported. Evaluating each month individually, the greatest number of EHI’s occurred during August (88%) with an EHI rate of 8.95/1000 AE. During August, the EHI rate was 6.31/1000 AE for heat cramps, 2.06/1000 AE for heat exhaustion and 0.58/1000 AE for heat syncope. Pearson correlations between the ACSM and DOD Heat Stress Index Charts and specific heat illnesses were not statistically significant relationships (p>.05). In our study we found a higher heat exhaustion injury rate compared to the NCAA surveillance data possibly due to differences in EHI definitions and reporting mechanisms. The incidence of heat illness in the months of September and October decreased dramatically, suggesting football athletes are at greatest risk of heat illness during August. Our data suggests that during the late summer, previously reported guidelines may overstate the risk of heat illness in highly trained football athletes practicing with the southeastern United States. The development of regionally specific heat index guidelines is recommended.

University of Minnesota M.S. thesis. November 2012. Major: Soil Science (Land and atmospheric science). Advisors: Carl J. Rosen and David J. Mulla. 1 computer file (PDF); xii, 267 pages appendix p. 246-267.

Post-emergence nitrogen (N) fertilizer is typically split applied to irrigated potato (Solanum tuberosum L.) in Minnesota in order to minimize the likelihood of nitrate leaching and to best match N availability to crop demands. Petiole nitrate-nitrogen (NO3-N) concentration is often used as a diagnostic test to determine the rate and timing of split applications, but determining spatial variability within a field using this approach is difficult. Canopy-level spectral measurements, such as hyperspectral and multispectral imagery, have the potential to be a reliable tool for making in-season N management decisions for precision agriculture applications. A two year field study was conducted on a loamy sand soil to evaluate the effects of variety, N treatment, and water stress on: (i) tuber yield, tuber quality, and plant N uptake characteristics; (ii) total N and NO3-N concentrations in petiole, leaflet, and whole leaf tissue samples throughout the season; and (iii) the ability of spectral data, especially from aerial hyperspectral and multispectral imagery, to predict leaf N concentration and tuber yield. The study included two potato varieties (Russet Burbank and Alpine Russet), two irrigation regimes (unstressed and stressed), and five N treatments categorized by three N rates (34 kg N ha-1, 180 kg N ha-1, and 270 kg N ha-1) in which the 270 kg N ha-1 rate had post-emergence N either split applied or applied early in the season. In addition, one of the 270 kg N ha-1 rates with post-emergence N split applied included a soil surfactant application. Reflectance measurements were made using both ground- and aerial-based platforms using several sensors: SPAD-502 chlorophyll meter, Cropscan MSR16R multispectral radiometer, AISA-Eagle hyperspectral camera, and Redlake MS4100 multispectral camera. Insufficient supplemental water during critical growth stages was found to negatively affect tuber yield, tuber quality, and plant N uptake, but surprisingly had a positive overall effect on frying quality. Because of its high yields, higher proportion of tubers >170g, higher N uptake, and similar processing qualities compared with Russet Burbank (RB), the Alpine Russet (AR) variety is attractive from both an economic and environmental perspective. For all N treatments except the 34 N early treatment, N use efficiency and N uptake efficiency values were less than 50 g g-1 and 50%, respectively. This indicates a relatively low efficiency of N use during 2010 and 2011 attributed to heavy leaching events during these years. Within the same N rates, N uptake efficiency was higher when post-emergence N was split applied, which is likely the result of less N being lost due to leaching. The use of the soil surfactant had a minimal effect on the parameters measured in this experiment. Tissue samples analyzed for NO3-N were very…

▼ Adequate and timely irrigation of crops is critical to maximise productivity and water use efficiency. Thus, having a capability of monitoring crop water status based on real-time monitoring can promise precise irrigation scheduling in a decision-making strategy. Unmanned aerial vehicle (UAV) remote sensing becomes a readily usable tool for agricultural water management with high temporal and spatial resolutions. This research estimates crop water stress and evapotranspiration (ET) by integrating very-high-resolution UAV imagery into crop water stress model and surface energy balance model in the aspects of crop water status and water use. Thermal infrared (TIR) and multispectral (MS) imagery from UAV systems are used as inputs of surface temperature and vegetation canopy structure with the aim to employ the least ground-based measurements. In the first part of the research, an adaptive estimation method of crop water stress index (CWSI) is proposed to determine automatic and crop-property-specific thresholds of reference boundary limits (Twet and Tdry). In the second part of the research, diurnal changes of plant water stress are explored by a series of UAV sensing at different times of the day. In the last part of the research, tree-by-tree instantaneous ET rate is estimated based on remote sensing energy balance (RSEB) model, presenting water losses of individual plant and assessing the intra-field variability of ET. This research contributes towards the improvement of the precise and rapid estimation of the plant water stress level by a quantitative index: crop water stress index (CWSI) using TIR-based UAV sensing in order to assess the spatial variability of water stress over heterogeneous agricultural fields. In addition, this research contributes to the analysis of the tree-by-tree ET which quantifies the plant water use as well as the assessment of the intra-field variability of ET. The results of the research demonstrate that: 1) the adaptive CWSI method showed strong relationships with stem water potential (ψstem) and stomatal conductance (gs) as plant physiological measurements. A higher correlation to ψstem and gs was obtained than the single reference CWSI; 2) Diurnal CWSIs showed significant correlation to gs according to the irrigation levels at three different times of the day (from morning to afternoon); and 3) the estimated ET was obtained with a strong linear relationship with leaf transpiration (Tr).

▼ Land degradation mainly soil erosion and deforestation are principal environmental problems exacerbating environmental stress and food insecurity in developing countries including Ethiopia. Ethiopia loses about 1.5 billion tons of soil per year, and about 1.5 million tons of grain, as a result of soil erosion. The present study is aimed at analyzing erosion hazard and vegetation degradation, which is leading to environmental stress in Lake Hawassa Catchment. Satellite images of Landsat TM 1986 and ETM+ 2005, 30m resolution SRTM-DTED, and data on land use and conservation practices collected from field and secondary sources such as; agro-meteorological and livelihood data, were major data types used for the study. Data analysis were undertaken using GIS and Remote Sensing techniques involving satellite image processing, identification of erosion hazard areas using USLE model and finally estimating the degree of environmental stress using multi-criteria weighted overlay analysis of rainfall variability, erosion hazard, vegetation index and livelihood system. The result of the study indicates that nearly 8% of the catchment, particularly the escarpments in Shamena_Hurufa, Boricha_Bushulo and Lalima sub-catchments are highly and severely degraded with long and wide gullies. Further more, the overlay analysis of land degradation, rainfall variability, vegetation index and the livelihood system indicated that 15% of the catchment is found with high degree of environmental stress; while 35 % is in the range of moderate stress. Similar to the results of erosion hazard, the western and northwestern parts of the catchment especially Boricha_Bushulo, Shamena_Hurufa, Lalima and Shashemene_Toga sub-catchments are with in a moderate to high environmental stress regime. Environmental stress areas are found both on the escarpment and on the plain. The underlying factors causing this stress could be different and thus need further investigation using other techniques. Therefore, in order to reverse the adverse effects of environmental degradation and stress in the catchment, appropriate conservation and rehabilitation measures, community based integrated watershed management initiatives and alternative livelihood approaches should be promoted and implemented. Advisors/Committee Members: Dr. Mohammed Umer (advisor).

▼ Load transfer analysis deals with an important function of engineering structure, which is the ability of structure in transferring imposed loads to the supporting points. Although stress value has proved to be an efficient index for performing the failure analysis, the necessity of defining an index for evaluation of structure stiffness has led to the introduction of the U* index theory. The U* index characterizes the internal stiffness distributions, as an indicator of the load transfer in the structure. Although U* index theory have been proven to be useful in design, it is missing necessary steps toward becoming a mature theory for structural analysis. Firstly, the U* index theory needed to be examined and validated by experimental testing. Therefore, an experimental setup was proposed and tested, and U* index theory was validated through comparison of results. Secondly, a systematic comparison between the conventional stresses analysis and the U* index analysis was lacking. Such comparison was made for structural analyses of a vehicle component. The results, also compared to observations of experimental testing showed that in some cases, application of conventional stress analysis might be limited or less precise. Thirdly, design modification capability is a significant feature of the U* index theory, and it was necessary to demonstrate that real life problems can benefit from this potential. In this study, sample structures representing the components of multiple passengers carrying vehicles were selected and analyzed by U* index theory and design modifications were proposed and implemented on the structure. Lastly, the U* index theory should be applicable to different types of problems, including nonlinear domain. Hence, to remove the limitations of linear analysis that is a part of the original theory, an extension of U* index theory to the nonlinear domain was proposed and tested. In summary, U* index theory provides an understandable explanation of load transfer in the structure and provides a general awareness regarding structural performance. He presented work showed that the existing methods of structural analysis have limitations in certain aspects that can be overcome by combining the perspective of U* index analysis to the existing structural analysis paradigm.

▼ The objectives of this study were: one, use electronic monitoring to determine feeding behavior patterns of grow-finish pigs throughout the year and to identify changes that occurred during heat stress events, and second, identify genetic markers associated with changes in feeding behavior due to heat stress. Pigs were placed in a grow-finish barn at approximately eight to ten weeks of age in 6 pens of 40 animals and monitored for 4-months. Gilts and barrows were from three different sire breeds, Duroc, Landrace, and Yorkshire. Each pen had one feeder, designed to feed 5 animals at a time. Feeders were fitted with an antenna and a multiplexer. Data were collected from antennas every 20 seconds. Outside temperature and humidity were obtained from a National Weather Station and used to calculate temperature humidity index (THI). Days in the study were partitioned into groups based on their maximum temperature humidity index (THI), where a THI less than 23.33°C was classified as “Normal”, a THI between 23.33°C and 26.11°C was classified as “Alert”, a THI between 26.11°C and 28.88°C was classified as “Danger”, and a THI greater than 28.88°C was classified as “Emergency”. Feeding behavioral differences among breeds and sex were observed across all THI categories. Landrace-sired pigs had fewer feeder visits compared to Duroc- and Yorkshire-sired pigs. Gilts had fewer feeder visits than barrows in all THI categories. A genome-wide association study for an animal’s change in feeding behavior between different THI categories was also conducted. Heritabilities for the difference in a pig’s feeder visits between each of the THI categories were low to moderate (0.136 to 0.406). Greater than 71% of genetic variation was explained by regions within eight chromosomes in the comparison between Danger and Emergency THI. Biological processes related to sensory perception and detection of chemical stimuli were over-represented in the set of genes located in these regions. Differences in feeding behavior patterns between THI categories demonstrate that heat stress affects sire breeds and sexes differently. Also genetic markers identified in this study may facilitate genetic selection for improved grow-finish performance during elevated ambient temperatures. Advisors/Committee Members: Joe Cassady.

▼ Mediante a utilização de tecnologias de deteção remota, integram-se diferentes fontes de dados da atmosfera e das culturas (imagens da superfície cultivada obtidas por satélite ou por plataforma aérea não tripulada), com os quais se monitorizam, com elevada resolução espacial e temporal, as necessidades hídricas das culturas, calculando a evapotranspiração cultural (ETc), indicadores biofísicos e índices de stress hídrico da vegetação (NDVI, Kc*, Kcb*, CWSI), que indicam a oportunidade e a dotação da rega, facilitando uma eficiente gestão da água, num regadio sustentável. A análise aplicou-se na área regional do Perímetro de Rega do Divor, tendo utilizado 7 parcelas experimentais, que são áreas regadas por rampas rotativas com a cultura do milho, cuja condução agrícola foi da responsabilidade dos respetivos agricultores. A tecnologia baseada nas imagens obtidas por satélite parece conjugar-se bem com a utilização de sensores (ou câmaras fotográficas), em plataformas voadoras a baixa altitude, resolvendo estas os problemas, inerentes à informação de satélite, nomeadamente à elevada periodicidade e à dependência da nebulosidade. Toda esta informação é georreferenciada, podendo servir de suporte à elaboração em SIG de mapas da situação hídrica e da oportunidade de rega das culturas, que poderão servir de base a um sistema de avisos de rega aos agricultores e gestão da rega no perímetro ou grande região de regadio; ABSTRACT:Through the use of remote sense technologies, data from different sources of the atmosphere and crops are integrated (images of the cultivated surface obtained by satellite or by flying unmanned platform), with which crop water requirements are monitored with high spatial and temporal resolution, by calculating evapotranspiration (ETc), biophysical indicators and indices of water stress of vegetation (NDVI, Kc, Kcb, CWSI), indicating the opportunity and the allocation of irrigation, facilitating an efficient water management for a sustainable irrigated agriculture. The analysis applied to Irrigated District of Divor, having used 7 experimental plots, which are areas watered by center-pivot systems, cultivated to corn, the agricultural driving having been the responsibility of the respective farmers. The technology based on satellite images seems to combine well with the use of sensors (or cameras), located on low altitude flying platforms, by solving some problems inherent to satellite information, in particular to the low frequency and the dependence of cloud cover. All this information is referenced, and can support the preparation of maps with GIS technology, describing water situation and opportunity of watering crops, which could serve as a basis for a farmers irrigation advice system and the region or the large perimeter irrigation management.

▼ Hemodynamics and shear forces are associated with pathological changes in the vascular wall and its function, resulting in the focal development of atherosclerosis. Flow complexities that develop in the presence of established plaques create environments favourable to thrombosis formation and potentially plaque rupture leading to stroke. The carotid artery bifurcation is a common site of atherosclerosis development. Recently, the multi-directional nature of shear stress acting on the endothelial layer has been highlighted as a risk factor for atherogenesis, emphasizing the need for accurate measurements of shear stress magnitude as well direction. In the absence of comprehensive patient specific datasets numerical simulations of hemodynamics are limited by modeling assumptions. The objective of this thesis was to investigate the relative contributions of various factors - including geometry, rheology, pulsatility, and compliance – towards the development of disturbed flow and multi-directional wall shear stress (WSS) parameters related to the development of atherosclerosis An experimental stereoscopic particle image velocimetry (PIV) system was used to measure instantaneous full-field velocity in idealized asymmetrically stenosed carotid artery bifurcation models, enabling the extraction of bulk flow features and turbulence intensity (TI). The velocity data was combined with wall location information segmented from micro computed tomography (CT) to obtain phase-averaged maps of WSS magnitude and direction. A comparison between Newtonian and non-Newtonian blood-analogue fluids demonstrated that the conventional Newtonian viscosity assumption underestimates WSS magnitude while overestimating TI. Studies incorporating varying waveform pulsatility demonstrated that the levels of TI and oscillatory shear index (OSI) depend on the waveform amplitude in addition to the degree of vessel constriction. Local compliance resulted in a dampening of disturbed flow due to volumetric capacity of the upstream vessel, however wall tracking had a negligible effect on WSS prediction. While the degree of stenosis severity was found to have a dominant effect on local hemodynamics, comparable relative differences in metrics of flow and WSS disturbances were found due to viscosity model, waveform pulsatility and local vessel compliance.

▼ Increased competition for water resources is placing pressure on the agricultural sector to remain profitable while reducing water use. Remote sensing techniques have been developed to monitor crop water stress and produce information for evapotranspiration (ET) based irrigation scheduling decisions. Use of stress detection methods allows producers to avoid exceeding set crop water stress levels and keep operations sustainable under limited irrigation despite some yield reduction. Remote sensing data such as spectral reflectance and infrared canopy temperature can be used to quantify crop water stress, often through the use of vegetation indices calculated from the near-infrared and red bands and temperature indices calculated from the thermal wavelength, respectively. Reference ET methods estimate water use based on crop characteristics and climactic parameters assuming optimum soil water conditions. In order to adjust crop ET for water limited conditions such as drought or water allocation restrictions, ET scaling techniques that are sensitive to crop development and stress are necessary. The performance of five remote sensing techniques to estimate corn ET under drought conditions in Northern Colorado were evaluated: one method based on air temperature, canopy temperature and relative humidity (Crop Water Stress Index (CWSI)), three methods based strictly on canopy temperature including Degrees Above Non-Stress (DANS), Degrees above Canopy Threshold (DACT), and Temperature Ratio, and one method based on multispectral vegetation indices (NDVI Ratio). Data were collected during 2010 through 2013 growing seasons at the USDA-ARS Limited Irrigation Research Farm near Greeley, CO. Varying water deficit levels were imposed on corn (Zea mays L.) under pressurized drip irrigation. ET estimates from the five remote sensing techniques were compared to soil water balance (via neutron probe) and ET calculations. Results showed that stress coefficient methods with less data requirements such as DANS and DACT are responsive to crop water stress as demonstrated by low RMSE of ET calculations comparable to more data intensive methods such as CWSI (CWSI = 0.77 mm/day, DANS = 0.80 mm/day, DACT = 0.80 mm/day, Tc Ratio = 0.83 mm/day, NDVI Ratio = 0.85 mm/day). Detailed tables indicate which remote sensing methods are appropriate to use given certain data availability and irrigation level, in addition to providing an estimation of the associated error in ET. Using the most appropriate stress coefficient method has the potential to improve irrigation scheduling and therefore allow crops to reach the maximum possible yield given the level of deficit irrigation. Methods with fewer data requirements, such as DACT with only a single canopy temperature measurement requirement, may be more appropriate to improve on-farm water management in certain situations. Results justify use of simplified measures of stress to improve deficit irrigation water management with limited data. Advisors/Committee Members: Chávez, José L. (advisor), DeJonge, Kendall (committee member), Niemann, Jeffrey (committee member), Schipanski, Meagan (committee member).

Biologija - Evoluciona biologija / Biology - Evolutionary biology

Uticaj sredinskog stresa na stabilnost razvića merističkih karakteristika (femoralne pore, subdigitalne lamele, supracilijarne granule) i oblika dorzalne strane glave ispitivan je poređenjem nivoa fluktuirajuće asimetrije (FA) navedenih karakteristika između populacija zidnog guštera (Podarcis muralis) koje naseljavaju urbana i ruralna staništa. Takođe, ispitano je i da li postoje razlike u nivou varijanse simetrične komponente oblika glave, alometriji simetrične komponente oblika i u nivou odstupanja od grupne alometrije između populacija koje naseljavaju ova dva tipa sredina. Pored toga, analizirano je i da li sredinski stres ima uticaja na performansu, kondicioni indeks i prevalencu i intenzitet krvnih parazita kao i da li jedinke koje su zaražene krvnim parazitima i jedinke sa niskim kondicionim indeksom pokazuju viši nivo asimetrije oblika glave. Osnovna hipoteza je bila da će populacije koje naseljavaju suboptimalne uslove životne sredine pokazivati viši nivo FA merističkih karakteristika, viši nivo FA oblika glave, viši nivo varijanse simetrične komponente oblika. Pored toga hipoteza je bila i da će postojati razlike u alometriji simetrične komponente oblika glave, nivou morfološke integracije između dva modula dorzalne strane glave između dva tipa populacija kao i veće odstupanje od grupne alometrije u urbanim populacijama. Takođe, pretpostavka je bila i da će urbane populacije pokazati veću prevalencu i intenzitet krvnih parazita, niži kondicioni indeks ali i da će inficirane jedinke i jedinke sa nižim kondicionim indeksom imati viši nivo FA oblika glave. U poređenju sa ruralnim populacijama, urbane su pokazale statistički značajno viši nivo FA za sve analizirane merističke karakteristike što ukazuje na to da je stabilnost razvića ovih karakteristika u ovoj sredini narušena. Takođe, uočeno je postojanje razlika u razvojnoj stabilnosti između analiziranih karakteristika što ukazuje na to da razvojna stabilnost može biti specifična za morfološke karakteristike. Nivo fluktuirajuće asimetrije je bio niži kod karakteristika koje su od većeg funkcionalnog značaja, što ukazuje da je kontrola razvića ovih karakteristika bila veća. Pored toga, uočeno je i da postoji značajna korelacija između FA femoralnih pora i subdigitalnih lamela što ukazuje na to da su ove karakteristike integrisane...

Biotehničke nauke - Genetika i oplemenjivanje biljaka / Biotechnical sciences - Genetics and Plant Breeding

Suša i osmotski stres, pored efekata na rastenje i razviće biljaka, dovode i do oksidativnog stresa i nastajanja velike količine reaktivnih kiseoničnih vrsta (ROS). Kako bi neutralisale štetne efekte ROS, biljke su razvile antioksidativne sisteme zaštite. Cilj istraživanja ove disertacije je bio da se detaljno prouče fiziološki i biohemijski procesi koji su u osnovi reakcija biljaka stočnog graška na sušu i osmotski stres. Cilj je bio i da se u ova ispitivanja uključe i molekularna istraživanja, koja bi, uz analizu procesa rastenja i drugih fizioloških procesa (aktivnost antioksidativnih enzima, akumulacije i distribucije stres hormona abscisinske kiseline), značajno doprinela razumevanju efekata, ne samo osmotskog i stresa suše, već i oksidativnog stresa na biljke stočnog graška. Istraživanja su vršena na 7 odabranih genotipova roda Pisum iz kolekcije Instituta za ratarstvo i povrtarstvo iz Novog Sada. Tretmani su obuhvatili dva eksperimentalna sistema: osmotski stres i sušu. Za indukciju osmotskog stresa su korišćene različite koncentracije rastvora osmotikuma PEG 6000 osmotskog potencijala (od -0,1MPa i -0,2MPa) primenjene u kraćem (10 dana) i dužem vremenskom intervalu (15 dana) kod klijanaca i ponika biljaka. Kao kontrolna varijanta je korišćena voda bez dodatka PEG 6000. Eksperiment suše je obavljen kod biljaka gajenih u kontrolisanim uslovima (u fitotronskoj komori) i to tako da su biljke zalivane optimalno do pojave trećeg para listova, a potom je suša u zemlištu izazvana prekidanjem zalivanja biljaka do 18% (umerena suša) i 9% sadržaja vode u spustratu (jaka suša). Biljke u kontroli su zalivane do optimalnog vodnog režima zamljišta (36% sadržaja vode u supstratu). U ogledu osmotskog stresa u fazi klijanja su obavljena fiziološka ispitivanja uticaja osmotskog stresa na % klijavosti i srednje vreme klijanja ili Mean Germination Time, dok su u fazi ponika obavljena ispitivanja dužine i biomase nadzemnog dela i korena, kao i odnosa suve mase nadzemnog dela i korena, a izračunat je i indeks tolerantnosti za nadzemni deo i koren...

▼ Cast aluminum alloys are common in automotive and aerospace applications due to their high strength-to-density ratio. Fracture data for cast aluminum alloys, such as fatigue life, tensile strength and elongation, are heavily affected by the structural defects, such as pores and bifilms. There have been numerous studies in which either fatigue performance or tensile deformation were characterized and linked to casting defects. However, a comprehensive study that correlates tensile and fatigue properties has not been reported. The present study is motivated to fill this gap. The main objective of the investigation is to analyze the link between tensile and fatigue performance of commonly used cast aluminum alloys, and determine whether fatigue performance of cast aluminum alloys can be predicted. To accomplish this task, four research questions were developed: (i) how well do equations developed to account for mean stress effects perform in cast aluminum alloys, especially in datasets with various levels of structural quality, (ii) is the strong correlation between fatigue life and structural quality index obtained from tensile data reported for A206 alloy castings applicable to other aerospace and automotive casting alloys, (iii) how do methods to estimate high cycle fatigue from tensile data perform with aluminum castings, and (iv) can the axial fatigue performance of an A356-T6 casting be predicted from rotating beam fatigue data. Among the three mean stress correction models analyzed by using seven datasets from the literature, the one developed by Walker with an adjustable exponent has provided the best fit. It has been hypothesized that the adjustable Walker parameter is related to the structural quality index, QT, estimated from tensile data. Results have shown that there is indeed a strong correlation between QT and the Walker parameter. Moreover the parameters of the xvi Weibull distribution estimated from corrected data have been found to be strongly influenced by the mean stress correction method used. Tensile and fatigue life data for 319, D357 and B201 aluminum alloy castings reported in the literature have been reanalyzed by using a maximum likelihood method to estimate Basquin parameters in datasets with run-outs, Weibull statistics for censored data and mean stress correction. After converting tensile data to QT, a distinct relationship has been observed between the expected fatigue life and mean quality index for all alloys. Moreover, probability of survival in fatigue life has been found to be directly linked to the proportions of the quality index distributions in two different regions, providing further evidence about the strong relationship between elongation, i.e., structural quality, and fatigue performance [1]. Specimen geometry has been found to make the largest difference whereas the two aerospace alloys, B201 and D357, with distinctly different microstructures, have followed the same relationship, reinforcing the findings in the literature that fatigue life in aluminum castings is mainly…

▼ The application of remote sensing technology in evaluating the crop water stress index is hampered by soil background effects related to partial ground cover. This study investigates the explicit contribution of soil information as an added dimension to the Vegetation Index Temperature/Trapezoid method, as well as data fusion technique to increase visual interpretation of water stress to formulate a new index of water stress. The study was conducted in Lubbock and Hale counties which includes an irrigation study at USDA-ARS in 2006-2008, Texas Tech irrigation studies at N Quaker and New Deal in 2007, and the AgriLife extension irrigation study in Halfway, TX in 2007-2008. Remote sensing missions were carried out using the Texas Tech Airborne Multispectral Remote Sensing System. Digital counts in Red and Near-Infrared images were converted to reflectance. Thermal Infrared images were converted into absolute temperatures using the known reflectance of calibration tarps and thermal sensors on the ground. Estimation of ground cover and the calculation of soil brightness were carried out using observed reflectance in the Red and NIR. The normalization of soil brightness into a Soil Brightness Index was carried out using the temporal reflectance values of soil brightness. Differences between surface temperature and air temperature were calculated. The fusion of the differences between the surface minus air temperatures, ground cover and soil brightness index into the Hue and Saturation & Intensity domain (respectively) improved the identification of water stress levels and the non-living features. Degree of water stress seemed to follow the ground cover across locations. The non-stressed cotton was observed consistently to be above 60 percent ground cover. Below this value, cotton begins to experience some degree of stress which can be associated with the acclimation of cotton to plant-available-water. Low ground cover however, can be non-stressed, with soil brightness index approaching 0. The 3-dimenstional CWSI is applicable to cotton under various irrigation types. The ground cover estimates and normalized soil brightness improved the discrimination of water stress levels using the 3-dimensional crop water stress index.

▼ The objective of this study was to explore the genetic component of heat stress in U.S. Holsteins using national milk yield data consisting of 57 million first-parity test-day records of 6 million Holstein cows that calved from 1993 through 2004 and weather records from 202 public weather stations. Seven temperature humidity indices were compared in a humid and semi-arid climate for their ability to detect a decline of milk yield due to heat stress. The index with a higher weight on humidity was the best in the humid climate. The index with a larger weight on temperature was the best heat stress indicator in the semi-arid climate. National genetic evaluation for heat tolerance was conducted using a repeatability test-day model. Based on estimated heat tolerance PTAs, the 100 most and 100 least heat-tolerant sires were selected. For each of the 200 sires, official U.S. PTAs from February 2006 were obtained. Sires that were the most heat tolerant transmitted lower milk yields with higher fat and protein contents than did sires that were the least heat tolerant. Daughters of the most heat tolerant sires had better udder and body composition, better type, lower dairy form, slightly higher TPI, longer productive life, higher daughter pregnancy rate, were easier calving and had better persistency than did daughters of the least heat tolerant sires. Heat stress was evaluated as a factor in the genotype x environment interaction on milk production in the United States. Data for the Southeast and Northeast were extracted from the national data set and analyzed separately. Two repeatability models with and without the effect of heat stress were implemented. Both models were fitted with the national and regional data sets. Correlations between breeding values of sires with • 100 and • 300 daughters in two regions were calculated. When heat stress was ignored (first model), the correlation of regular breeding values between regions for sires with • 100 (• 300) daughters was 0.85 (0.87). Heat stress as modeled here explains only a small amount of genotype by environment interaction, partly because test day records provide only snapshots of heat stress over a hot season.
