    Mn3x_{3-x}Cox_{x}Ga epitaxial thin films were grown on MgO substrates by magnetron co-sputtering. Structures were tetragonal or cubic depending on Co content. Composition dependence of saturation magnetization and uniaxial magnetic anisotropy KuK_u of the films were investigated. A high KuK_u (1.2 MJ m3^{-3}) was achieved for the Mn2.6_{2.6}Co0.3_{0.3}Ga1.1_{1.1} film with the magnetic moment 0.84μB\mu_B. Valence band spectra were obtained by hard X-ray photoelectron spectroscopy. Sharp peaks in the cubic case, which were absent in the tetragonal case, prove that a van Hove singularity causes a band Jahn-Teller effect with tetragonal distortion. Observations agree well with the first-principles calculations

    In this research, we analyzed and discussed the content composition of four fundamental concepts of society in Human Society and Environment Syllabus 2006 edition (HSIE 2006 edition) in New South Wales, Australian Commonwealth. And it was aimed to obtain suggestions on the content composition of the new elementary Social Studies in Japan, based on competency. As a main result, in the description of the HSIE 2006 learning outcome, it was stated from four strands, that is,four fundamental concepts of society which is a framework of knowledge and understanding. In the description of the curriculum scope, it is thought that contents are composed of four levels of hierarchy (I:fundamental concepts, II:lower concept, III:lowest concept, IV:meaning of phenomenon which becomes contents of learning). Because such features become the framework of the entire curriculum, the HSIE 2006 edition was considered as a curriculum of content base. As suggestions, we should discuss the hierarchy of contents and the system of how to accumulate it, and theoretically should discuss the way of mutual complementary relations of engaging as a function of fundamental concepts of society in contents and method of learning

    Extractability, extractable protein compositions, technological-functional properties of pea (Pisum sativum) proteins from six genotypes grown in Serbia were investigated. Also, the relationship between these characteristics was presented. Investigated genotypes showed significant differences in storage protein content, composition and extractability. The ratio of vicilin: legumin concentrations, as well as the ratio of vicilin + convicilin: Legumin concentrations were positively correlated with extractability. Our data suggest that the higher level of vicilin and/or a lower level of legumin have a positive influence on protein extractability. The emulsion activity index (EAI) was strongly and positively correlated with the solubility, while no significant correlation was found between emulsion stability (ESI) and solubility, nor between foaming properties and solubility. No association was evident between ESI and EAI. A moderate positive correlation between emulsion stability and foam capacity was observed. Proteins from the investigated genotypes expressed significantly different emulsifying properties and foam capacity at different pH values, whereas low foam stability was detected. It appears that genotype has considerable influence on content, composition and technological-functional properties of pea bean proteins. This fact can be very useful for food scientists in efforts to improve the quality of peas and pea protein products

    Whole-profile soil organic matter content, composition, and stability under cropping systems that differ in belowground inputs

    Subsoils have been identified as a potential carbon sink because they typically have low soil organic carbon (SOC) concentrations and high SOC stability. One proposed strategy to increase SOC stocks is to enhance C inputs to the subsoil by increasing crop rotation diversity with deep-rooted perennial crops. Using three long-term field trials in Iowa (study durations of 60, 35, and 12 years), we examined the effects of contrasting cropping systems [maize (Zea mays L.)-soybean (Glycine max (L.) Merr) (= two-year system) vs. maize-soybean-oat (Avena sativa L.)/alfalfa (Medicago sativa L.)-alfalfa or maize-maize-oat/alfalfa-alfalfa (= four-year system)] on above- and below-ground C inputs, as well as the content, biochemical composition, and distribution of SOC among physical fractions differing in stability to 90 cm depth. Average annual total C inputs were similar in the two-year and four-year systems, but the proportion of C delivered belowground was 20–35 % greater in the four-year system. Despite the long duration of these studies, the effect of cropping system on SOC content to 90 cm was inconsistent across trials, ranging from −7 % to +16 % in the four-year relative to the two-year system. At the one site where SOC was significantly greater in the four-year system, the effect of cropping system on SOC content was observed in surface and subsoil layers rather than limited to the subsoil (i.e., below 30 cm). Cropping system had minimal effects on biochemical indicators of plant-derived organic matter or on the proportions of SOC in labile particulate organic matter versus stable mineral-associated organic matter. We conclude that adoption of cropping systems with enhanced belowground C inputs may increase total profile SOC, but the effect is minimal and inconsistent; furthermore, it has minor impact on the vertical distribution, biochemical composition, and stability of SOC in Mollisols of the Midwest U.S

    Model-driven description and validation of composite learning content

    Authoring of learning content for courseware systems is a complex activity requiring the combination of a range of design and validation techniques. We introduce the CAVIAr courseware models allowing for learning content description and validation. Model-based representation and analysis of different concerns such as the subject domain, learning context, resources and instructional design used are key contributors to this integrated solution. Personalised learning is particularly difficult to design as dynamic configurations cannot easily be predicted and tested. A tool-supported technique based on CAVIAr can alleviate this complexity through the validation of a set of pedagogical and non-pedagogical requirements. Courseware validation checks intra- and inter-content relationships and the compliance with requirements and educational theories

    Title from PDF of title page (University of Missouri--Columbia, viewed on Mar. 15, 2010).The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Dissertation advisors: Dr. Ingolf U. Grün, Dr. Mengshi Lin.Vita.Includes bibliographical references.Ph. D. University of Missouri--Columbia 2008.Dissertations, Academic -- University of Missouri--Columbia -- Food science.This study evaluated the feasibility of fortifying fresh pasta with beef heart, a beef by-product high in coenzyme Q₁₀. Incorporating freeze-dried beef heart into pasta significantly increased coenzyme Q₁₀ and protein content, which were unaltered by cooking, but also significantly changed physical attributes, including texture and color, of the fortified pasta products. Alterations in pasta matrixes, after partially replacing durum wheat flour with freeze-dried beef heart, were evaluated at the molecular level using vibrational spectroscopic methods, FT-IR and Raman spectroscopy accompanied by multivariate statistical analyses. The results were deducted that lipid-protein interactions, [beta]-sheet arrangement, the starch network, and cysteine thiol groups might contribute to hardness and chewiness of the pasta products. The lipid fraction and [beta]-sheet alignment were possibly involved in pasta adhesiveness. Pasta firmness might be caused by [beta]-sheet structure and the polysaccharide network. Pasta cohesiveness might be affected by the [alpha]-helical structures and hydrogen bonds in the gluten network. It was concluded that FT-IR and Raman Spectroscopy can be applied to evaluate physiochemical changes of pasta and showed a potential use for quality assessment in pasta products because of rapidly and non-destructively determining changes related to many food components, including protein, carbohydrate, and lipid, at one time measurement

    Changes in the Content, Composition and Localization of Foliar Phenolic Compounds of Strawberries as Influenced by Nitrogen Regimen

    To meet the increasing food demand, conventional agriculture practices emphasizes on quantitative yield and often involves intensification of nitrogen fertilizers. However, owing to the high mobility in the soil, nitrogen leaching imposes serious consequences on environment and subsequently on human health. Although the quantitative yield is predominantly determined by primary metabolism, the secondary metabolism in the plant not only function as response molecules against biotic and abiotic stress but also determines the qualitative composition of the crop. Nitrogen deficiency limits growth more than photosynthesis, leading to accumulation of the carbon based secondary precursors. Nitrogen deficiency or excess is also associated with increase in the reactive oxygen species (ROS) further driving the biosynthesis of secondary metabolism and utilization of the carbon precursors. Furthermore, the leaves are documented to accumulate a higher proportion of phenolics and exhibit translocation across the plants based on the environmental trigger and developmental stage. Polyphenols constitute one such class of carbon based secondary metabolites biosynthesized throughout the plant’s life and have key role as signaling molecules, free radical scavengers etc. Although, the presence of an aromatic carbon ring structure is the characteristic of phenolics, there exist vast structural diversity based on the addition and modification to the core ring structure and location of one or more hydroxyl groups. These distinctions both within and between the different classes of phenolics further dictates their biological activity and efficiency. However, variation in the quantitative and qualitative metabolic pool of phenolics in the plant could not only be driven by the stress stimuli but also by the extent of the stress. Thus, the present study investigated the content, composition and localization of foliar phenolics from two cultivars of Fragaria ananassa (cv. Camarosa and cv. Albion) exposed to four different nitrogen (N) fertilization treatments (control, 8mM N, 16mM N and 30mM N). Using a non-targeted metabolomics approach, present study not only exhibited a non-linear response in the content between foliar phenolic classes but also emphasizes the compositional variation and preferential localization of the biosynthesized phenolics. The tentatively identified metabolites encompassed different groups of non-anthocyanic phenolics namely, hydrolysable tannins (simple galloyl glucoses, ellagic acid derivatives and ellagitannins), hydroxycinnamate derivatives, flavones, flavonols, flavan-3-ols and oligomeric proanthocyanidins. For both the cultivars, the content of different phenolic classes showed the general trend of increase with decrease in N concentration, however, the magnitude of response varied between both the cultivars and the different classes. Primary metabolites viz. sugars, organic acids and the key amino acid glutamine, did not exhibit a significant response to the applied N treatments, across both the cultivars. Total hydrolysable tannin (HTs) decreased by 70% as N concentration increased from 8mM N to 16mM N in cv. Camarosa and no variation across the treatments in cv. Albion. However the total phenylpropanoids decreased (P From the study, we concluded that along with the increase in carbon based secondary compounds under nitrogen deficiency; the variation within the class of phenolics is linked to the biosynthetic origin and physiological role of the phenolic class
