Barley yellow dwarf epidemiology

Barley yellow dwarf (BYD) disease is induced by viruses that are vectored by aphids. The viruses infect grasses and cause severe damage on oats, barley and wheat worldwide. This thesis focuses on the following aspects of the BYD disease epidemiology: occurrence and genetic variability of viruses causing BYD disease, aphid population parameters and host plant damage caused by virus infection. The virus species Barley yellow dwarf virus-PAV (BYDV-PAV), Barley yellow dwarf virus-MAV (BYDV-MAV) and Cereal yellow dwarf virus-RPV (CYDV-RPV) were found in Latvia. The three year incidence of BYDV/CYDV ranged from 9 to 15% in symptomatic leaf samples of spring cereals and from 2 to 19% in random samples of pasture grasses. Sequence analyses of partial coat protein encoding region revealed close genetic relationships among all isolates of BYDV-MAV. The isolates from Sweden and Latvia are the first published BYDV-MAV sequences from Europe. Swedish and Latvian isolates of BYDV-PAV were found in two host-specific groups. A distinct variant of BYDV-PAV was discovered in Latvia and proposed to belong to a new species. Monitoring of aphid flight activity over eight years indicated cereal aphid Rhopalosiphum padi (L.) predomination over Sitobion avenae (Fab.) and Metopolophium dirhodum (Walk.). Positive linear correlations were observed between suction trap catches and population size of R.padi in a field, and between spring and summer migrations of R.padi, but not for their summer/autumn and autumn/next spring migrations. Aphid density in a field was well predicted from proportion of tillers infested and the Nachman model. A specific BYDV-PAV isolate inoculated to oats at four different growth stages decreased the grain biomass and plant height, especially when inoculated in early growth stages, but increased the number of tillers and panicles per plant. The infection did not affect 1000-kernel weight and grain volume weight. In conclusion, the results of this thesis add new knowledge and contribute to understanding the parts of the complex system of BYD disease.
Security in PKI/PMI-Based Workflow Security Model *

In consideration of simple workflow security model, there are some defects such as simple authentication, inflexible authorization and absent of audit, etc. However, based on the intensive research of security needs of WfMS, and by involving PKI/PMI technology, an enhanced workflow security model can be a viable choice. This model introduces strong factor authentication by utilizing PKI, T&RBAC access control by utilizing PMI and by utilizing digital signature and DTS to provide non-repudiation and existing services. The requirements of security audit also can be satisfied well. Comparing with simple workflow security model, theory study shows this PKI/PMI-based model improves the safety and flexibility significantly. A convenient and reliable solution for Data Privacy, Data Integrity, data Availability and Non Repudiation is adjusted to the requirements of workflow. The risks from illegal and unauthorized operations are reduced to minimum.
Functionome Alkylation Sensitivity Screens Reveal a Conserved Cross-species

To identify genes that contribute to chemotherapy resistance in glioblastoma,we conducted a synthetic lethal screen in a chemotherapy-resistant glioblastoma-derived cell line with the clinical alkylator temozolomide (TMZ) and an siRNA library tailored toward "druggable" targets. Select DNA repair genes in the screen were validated independently, confirming theDNA glycosylases uracil-DNA glycosylase (UNG) andA/G-specific adenineDNA glycosylase (MYH) as well as methylpurine-DNA glycosylase (MPG) to be involved in the response to high dose TMZ. The involvement of UNG and MYH is likely the result of a TMZ-induced burst of reactive oxygen species. We then compared the human TMZ sensitizing genes identified in our screen with those previously identified from alkylator screens conducted in Escherichia coli and Saccharomyces cerevisiae. The conserved biologic processes across all three species compose an alkylation functionome that includes many novel proteins not previously thought to impact alkylator resistance. This high-throughput screen, validation and cross-species analysis was then followed by a mechanistic analysis of two essential nodes: base excision repair (BER)DNAglycosylases (UNG, human andmag1, S. cerevisiae) and protein modification systems, including UBE3B and ICMT in human cells or pby1, lip22, stp22 and aim22 in S. cerevisiae. The conserved processes of BER and protein modification were dual targeted and yielded additive sensitization to alkylators in S. cerevisiae. In contrast, dual targeting of BER and proteinmodification genes in human cells did not increase sensitivity, suggesting an epistatic relationship. Importantly, these studies provide potential new targets to overcome alkylating agent resistance. Mol Cancer Res; 10(12); 1580–96. 2012 AACR.
Study of Microstrain and Stress in Non-Planar Palladium Membranes for Hydrogen Separation

Palladiums tubular membranes are developed to operate up to 400 °C, for the synthesis of H2 and for the separation of CO2 in Water Gas Shift (WGS) processes and reforming gas of methane [. Palladium has FCC lattice that allows the separation of hydrogen from carbon dioxide through a solution-diffusion mechanism [. To ensure high selectivity in the separation process, the functional Pd layer on the porous substrate of the membranes must have a microstructure with low defects and free from residual stresses [. MicroXRD measurements were performed to evaluate the effect of the stress-relief heat treatment, carried out for different time and temperatures, on the palladium layer. Microstrains were assessed before and after stress-relief by the Williamson-Hall method [. The use of microdiffraction was mandatory considering the tubular shape of membranes. The data were corrected for elastic anisotropy of palladium and the altered Williamson-Hall method was successfully applied.The XRD two-dimensional (2D) images and the integrated spectra collected from the samples allowed to study also the evolution of Pd microstructure and the reduction of micro-stresses due to stress relief. The results of the study allowed to identify the optimal thermal profile for the heat treatment of palladium membranes.
corticotropin-releasing hormone challenge of Brahman cattle following transportation Sexually dimorphic stress and pro-inflammatory cytokine responses to an intravenous

This study was designed to characterize potential sexually dimorphic stress and immunological responses following a corticotropin-releasing hormone (CRH) challenge in beef cattle. Six female (heifers) and six male (bulls) Brahman calves (264 12 d of age) were administered CRH intravenously (0.5 mg of CRH/kg body mass) after which serum concentrations of cortisol increased from 0.5 h to 4 h. From 1 h to 4 h after CRH administration, serum cortisol concentrations were greater in heifers than in bulls. In all cattle, increased serum concentrations of TNF-a, IL-6 and IFN-g were observed from 2.5 h to 3 h after CRH, with greater concentrations of IFN-g and IL-6 in heifers than bulls. Heifer total leukocyte counts decreased 1 h after CRH administration, while bull leukocyte counts and percent neutrophils decreased 2 h after CRH administration. Heifers had greater rectal temperatures than bulls, yet rectal temperatures did not change following administration of CRH. There was no effect of CRH administration on heart rate. However, bulls tended to have increased heart rate 2 h after CRH administration than before CRH. Heifer heart rate was greater than bulls throughout the study. These data demonstrate that acute CRH administration can elicit a pro-inflammatory response, and cattle exhibit a sexually dimorphic pro-inflammatory cytokine and cortisol response to acute CRH administration.
Effect of organic, low-input and conventional production systems on yield and diseases in winter barley

The effect of organic, low-input and conventional management practices on barley yield and disease incidence was assessed in field trials over two years. Conventional fertility management (based on mineral fertiliser applications) and conventional crop protection (based on chemosynthetic pesticides) significantly increased the yield of winter barley as compared to organic fertility and crop protection regimes. Severity of leaf blotch (Rhynchosporium secalis) was highest under organic fertility and crop protection management and was correlated inversely with yield. For mildew (Erysiphe graminis), an interaction between fertility management and crop protection was detected. Conventional crop protection reduced severity of the disease, only under conventional fertility management. Under organic fertility management, incidence of mildew was low and application of synthetic pesticides in “low input” production systems had no significant effect on disease severity.
Short title : Regulation of rice sucrose partitioning by OsQUA 2 2 3 Rice sucrose partitioning mediated by a putative pectin methyltransferase and 4 homogalacturonan

47 Homogalacturonan (HG) is the main component of pectins. HG methylesterification has 48 recently emerged as a key determinant controlling cell attachment, organ formation, and 49 phyllotaxy. However, whether and how HG methylesterification affects intercellular 50 metabolite transport has rarely been reported. Here, we identified and characterized 51 knockout mutants of the OsQUA2 gene encoding a putative pectin methyltransferase 52 (PMT). Osqua2 mutants exhibit a remarkable decrease in the degree of 53 www.plantphysiol. org on May 11, 2017 Published by www.plantphysiol. org Downloaded from Copyright © 2017 American Society of Plant Biologists. All rights reserved. 3 methylesterification (DM) of HG in the culm-sieve element (SE) cell wall, and a markedly 54 reduced grain yield. The culm of Osqua2 mutant plants contain excessive sucrose, and a 55 CO2 feeding experiment showed that the sucrose over-accumulation in the culm was 56 caused by blocked sucrose translocation. These and other findings demonstrate that 57 OsQUA2 is essential for maintaining a high DM of HG in the rice culm-SE cell wall, 58 which may be critical for efficient sucrose partitioning and grain filling. In addition, our 59 results suggest that the apoplastic pathway is involved in long-distance sucrose transport in 60 rice. The identification and characterization of the OsQUA2 gene and its functionality 61 revealed a previously unknown contribution of HG methylesterification and provided 62 insight into how the modification of cell wall regulates the intercellular transport in plants. 63 64
Application of binary logistic regression in credit scoring

Nowadays, demand for loan products is growing day by day. Also, loan applicants have become more demanding, than they were before. They want to receive the response from bank as soon as possible. In order to resist the growing competition banks develop new quantification techniques which accelerate and automate the decision making process. One of these techniques is credit scoring. Credit Scoring is one of the most widely used instruments which is applied by lenders decide whether to approve or reject the loan application. In this Master’s thesis an overview of credit scoring is given. The most essential objective of this thesis is to show the application of logistic regression in Credit score models. Other methods of credit scoring will also be noted, but not in extensive detail. The study ends with a practical application of logistic regression for a credit scoring model on real data of loan applicants.

FAR INFRARED GALAXIES IN AKARI’S EYE

We present the results of Spectral Energy Distribution (SED) fitting of far-infrared galaxies detected in the AKARI Deep Field-South (ADF-S) Survey and discuss their physical properties. Additionally, we perform a comparison between photometric redshifts estimated using only optical and both optical and infrared data. We conclude that our sample consists mostly of nearby galaxies rich in dust and young stars. We observe an improvement in the estimation of photometric redshifts when the IR data are included, comparing to a standard approach based mainly on the optical to UV photometry.
Indices in Obese Adolescents Comparison of Oral and Intravenous Glucose Tolerance Test Derived Sensitivity and Secretory

Background. Insulin resistance increases type 2 diabetes risk in obese adolescents. Thus, quantitative tools measuring insulin sensitivity and secretion are important for risk assessment. Methods. Forty-four obese pubertal adolescents underwent oral glucose tolerance test (OGTT) and frequently sampled intravenous glucose tolerance test (FSIGT). We correlated OGTT-derived whole body sensitivity index (WBISI) with FSIGT-derived insulin sensitivity index (Si). Insulinogenic index (IGI) from OGTT was compared with acute insulin response to glucose (AIRg) from FSIGT. Results. Fasting insulin (r = −.64, P < .0005) and glucose (r = −.39 P ≤ .0005) predicted Si. The OGTT-derived index WBISI correlated with the FSIGT-derived Si (r = .608, P < .0005). IGI correlated with AIRg from FSIGT (r = .704, P < .0005). Conclusions. OGTT-based measures correlated with FSIGT-derived measures of insulin sensitivity and secretion. In particular, we demonstrated that WBISI can be a reliable alternative to FSIGT-derived Si in clinical settings where OGTT is a more feasible option.
Intraspecific Differences Regarding Granular Polymorphism in Granular Ducts’ Cells in Rats’ Mandibular Gland

Mandibular gland ducts’ system in rodents consist of intralobular ducts (intercalated, granular, striated) and interlobular one (main excretory duct). Granular ducts are located between intercalated and striated ducts, being present only in mandibular gland of the mouse, rat, hamster and gerbil. The biological material used for this study was represented by two strains from the same species, three Wistar rats and three Brown Norway rats. After the animals were euthanized, the mandibular glands were harvested and then processed for histological investigations. The tissue fragments were sectioned at 5μm thickness and then stained the sections using TricromGoldners method. Our results emphasize that the granular ducts are well developed; regarding the shape, they are convoluted in both Wistar and Brown Norway rats, without any significant differences between the two strains. In Wistar rat, the granules in granular ducts cells are small to medium in size, with discrete polymorphism. In Brown Norway rat, the cytoplasm is loaded with granules as in Wistar rat, but these are several times larger and more polymorphic.
Molecular characterization of potato (Solanum tuberosum L.) genotypes using random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers

19 random amplified polymorphic DNA (RAPD) and five Inter-simple sequence repeat (ISSR) primers were used to characterize 35 potato accessions originating from Mexico, Europe and U.S.A, with the aim of generating information on the genetic diversity and relationship among the genotypes for better exploitation in breeding programs. A total of 222 and 82 loci were generated by the RAPD and ISSR primers, respectively. Both RAPD and ISSR primers revealed 81.45 and 82.98% polymorphism, respectively. Mantel test showed no correlation between RAPD and ISSR (0.27), RAPD and RAPD + ISSR (0.47) similarity matrices. However, a high level of correlation (0.74) was observed between ISSR and RAPD + ISSR similarity matrices. The ISSR marker was found to be more efficient compared to RAPD marker, thereby influencing more the consensus data. The use of consensus data generated more information related to genetic diversity in potato. RAPD and ISSR markers successfully differentiated between the potato accessions and subgrouped the genotypes based on origin. Information on genetic diversity and relationships will be useful in the selection of parents and mapping studies. Key words: Solanum tuberosum L. , random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), genetic diversity, relationships.
Short communication : Analysis of association between the prion PRNP

The purpose of this study was to analyze associations between polymorphisms in the PRNP gene and ewe milk traits. A total of 242,565 lactations of the Latxa breed were used. Milk, fat and protein yields, and fat and protein content from black-faced Latxa from Spanish Basque Country, black-faced Latxa from Navarra, and blond-faced Latxa were collected. To evaluate evidence of association, the different traits were analyzed using an animal model, where the PRNP genotype effect was included or not as a random effect. Adding the PRNP effect to the model improved the fitting for milk yield in black-faced Latxa from Spanish Basque Country and in blond-faced Latxa, for fat yield in black-faced Latxa from Navarra, and for protein yield in blond-faced Latxa. However, the proportion of the phenotypic variance explained by the PRNP effect for milk yield (1.0 × 10), fat yield (3.6 × 10) and protein yield (9.4 × 10) were near zero. The PRNP locus accounts for about 0.5, 1.5, and 0.4% of total genetic (PRNP and polygenic) variance in milk, fat, and protein yield. These values indicated that the PRNP effect is not relevant regarding genetic additive contribution. For breeding purposes, it is unlikely that selection for scrapie resistance will have an effect on the milk traits studied in the Latxa breed.
The Influence of Biorganic Fertilizers on Productivity and Quality of Vegetables in the System of "Green" Vegetable Farming in the Conditions of the South-East of Kazakhstan

The purpose of the research was to study an influence of biofertilizers and new types of biological products for the yield and quality of vegetables in the South-East of Kazakhstan. In Kazakhstan, organic farming began to develop after the adoption of the Act "On Organic farming" in 2015. The development of "green" technologies is very important for the production of organic vegetable products in the country. The goal is the scientific provision of organic vegetable farming in Kazakhstan. Methods of research are classical, generally accepted in vegetable growing, agrichemistry and soil science. The studies on "green" agritechnologies in the vegetable farming of Kazakhstan are conducted for the first time, which determines their relevance and scientific novelty. The aim of the research was to study an influence of local organic fertilizers and new types of biofertilizers while growing the most popular vegetable crops (cabbage, cucumber, tomato) and replace chemical fertilizers by them in the condition of the South-East of Kazakhstan. Also, development of an alternative biological system for the fertilization of vegetable crops by using local organic fertilizers and biopreparations. It was experimented that all types of organic fertilizers and biopreparations ensure a sufficiently large yield of vegetables. It is noted that some organic fertilizers are more effective than mineral fertilizers. The bioorganic fertilizers positively influenced the quality of vegetables, so that the content of dry substances, sugars and vitamins increased in the production. The conclusion was made on the possibility of using local organic fertilizers and new biopreparations available to farmers of the country for growing organic vegetables. Depending on the types of organic fertilizers and biopreparations, the yield of cabbage increased by 15.2-47.2%, cucumber by 17.4-88.7% and tomato by 14.4-47.1%. Moreover, an improvement of the quality indicators of vegetables also showed in the crops.
Study of the Naphthenic Corrosion of AISI 316 and AISI 1020 Steels by Light, Scanning Electron and Atomic Force Microscopies (LM, SEM and AFM)

Corrosion processes were evaluated for AISI 316 and AISI 1020 steels by scanning electron microscopy (SEM), atomic force microscopy (AFM) and light microscopy. Coupons were immersed in four crude oil samples with different total acid numbers (TANs) for 48 days at room temperature. The steels were also exposed to three blends (B1-B3), produced by quaternary mixtures of the oils, with lower TANs than their respective original oils. SEM micrographs showed pitting-type corrosion in most cases. AFM imaging showed drastic changes in the peak-to-peak values, topographic profiles and phase images of the AISI 1020 coupons exposed to all oils and blend B3 as compared to the unexposed steel. Defects were produced on the surface of almost all the samples exposed to naphthenic corrosion. Exposure to the oil blends reduced the extent of the naphthenic corrosion on the coupons, especially blends B1 and B2. The oil mixtures (blends) reduced corrosion.
Size and shape control for water-soluble magnetic cobalt nanoparticles using polymer ligands

We report a synthesis of monodisperse water-soluble magnetic Co nanoparticles using a facile reduction method in aqueous media in the presence of alkyl thioether end-functionalized poly(methacrylic acid) (PMAA-DDT) ligands. The size and shape of the nanoparticles are both tunable by varying synthesis conditions. The size of the spherical nanoparticles can be tuned between 2–7.5 nm by changing the concentration of the polymer. Our synthesis approach also provides a route for producing much larger spherical nanoparticles of 80 nm as well as anisotropic nanorods of 15 × 36 nm. The spherical nanoparticles are superparamagnetic at room temperature. The nanoparticles can be stable in water for up to eight weeks when 0.12 mM PMAA-DTT with molecular weight of 13500 g mol−1 is used as ligand.
Imperfect Information, Macroeconomic Dynamics and the Yield Curve: An Encompassing Macro-Finance Model

In this paper we estimate an encompassing Macro-Finance model allowing for time variation in the equilibrium real rate, mispricing and learning dynamics. The encompassing model specification incorporates (i) a small-scale (semi-) structural New-Keynesian model, (ii) flexible price of risk specifications, (iii) liquidity premiums in the form of (constant) deviations from (Gaussian) no-arbitrage and (iv) learning dynamics. This model is estimated on US data using MCMC techniques. We find that the encompassing model outperforms significantly standard Macro-Finance models in terms of marginal likelihood and BIC. Three findings stand out. First, unlike standard Macro-Finance models, a substantial fraction of the variation in long-term yields is attributed to changes in the perceived equilibrium real rate. Second, statistically and economically significant learning effects, especially for inflation expectations, are found. Finally, historical decompositions show that the model can replicate the US yield curve dynamics over the period 1960-2007.
