THE ROLE OF TRACE ELEMENTS IN ASSURING QUALITY OF FODDS

In the article the results of studying of features of role of trace elements in the formation of the quality indicators of seeds of oilseed radish in two varieties are reflected. Systematized the views of various researchers on the processes of formation of oil content in cruciferous crops in general and radish oilseed in particular, given the current strategy of fertilizer oilseed crops of the family Cruciferae. Studied feature of the stages of the implementation and effectiveness of mono-component micronutrients in the form of easily soluble and readily available substances. The studied set of microelements included the recommended list of physiologically important components of modern microfertilizer formats and their chemical composition in order to optimally analyze the effectiveness of application for their single application in two key phases of oilseed radish – the phenological phase of stalking and the phenological phase of flowering. The use of each of micronutrients was effective and substantial compared to the oil content of seeds of both cultivars of oilseed radish given the level of oil content in seeds in control variant. The magnitude of the variation in the oil index was estimated taking into account the differences in the nature of the hydrothermal regimes of the research period. This allowed to determine the degree of genotypic nature of the formation of the oil content of seeds in oilseed radish and the possibility and effectiveness of selection of appropriate genotypes with the prospect of obtaining oil in the technical direction of use. Also assessed the role of individual micronutrients in the magnitude of the volatility of oil content in seeds of oilseed radish. Determined that the increase of oil content in seeds of oilseed radish the addition of various trace elements in the range of 0.3-1.4% from the close dynamic the resulting effective action on the formation of this indicator in the form of Co>Zn>Cu>B>Mn>Mo. It is proved that the efficacy of these minerals increases with introducing them into the flowering stage, which is a critical period regarding the implementation of the reproductive potential of the plants of oilseed radish and the formation of appropriate indicators of the quality of its seeds. The recommendations for further research in the field of optimization of fertilizer radish seeds and micronutrients were formulated. Key words: oilseed radish, fertilizer, microelements, seed quality, oil content, variety.

Newark Basin

The Byram and Walls Island members in the lower and upper sections, respectively, of the Lockatong Formation in the Newark basin near the border between Pennsylvania and New Jersey were chosen to assess (i) the role of euxinic/anoxic conditions in sequestering arsenic (As) and other trace elements and (ii) the redistribution of these elements during catagenetic transformations. ἀese members are rich in organic matter and host pyrite which occurs as disseminations, small patches, and subparallel veins. ἀe sulfur isotope values of pyrite samples range between -7.5 and 0.5 ‰CDT (average = -3.5‰CDT). ἀe negative δ34S values are indicative of Bacterial Sulfate Reduction (BSR) under low temperature and euxinic/anoxic conditions. ἀe total organic carbon (TOC) values in this member ᴀuctuate between 0.5 and 2.1%. ἀese euxinic/anoxic conditions enhanced the incorporation of As and other trace elements in both organic matter and pyrite. ἀe As concentrations range from 13 to 800 mg/kg and from 1.4 to 34 mg/kg in pyrite and black shale samples, respectively. Rock Eval analyses reveal that organic matter is over-mature which altered the correlation between TOC and As. ἀe thermal cracking of organic matter resulted in the removal of these elements from organic matter and their subsequent incorporation in pyrite and bitumen. Organic matter- and pyrite-rich anoxic black shale layers and bitumen veins are potential sources of arsenic in groundwater in the Newark basin, with arsenic values that reach up to 215 μg/L.

This article introduces Cognitive Health Counseling 40+ (CH.CO40+), an individualized intervention that is conceptually based on the orchestration model of quality-of-life management ( Martin & Kliegel, 2010 ) and aims at improving satisfaction with cognitive health in adults aged 40 years and older. We describe the theoretically deduced characteristics of CH.CO40+, its target group, its multifactorial nature, its individualization, the application of subjective and objective measures, the role of participants as agents of change, and the rationale for choosing participants’ satisfaction with their cognitive health as main outcome variable. A pilot phase with 15 middle-aged and six older adults suggests that CH.CO40+ attracts, and may be particularly suitable for, subjective memory complainers. Implications of the pilot data for the further development of the intervention are discussed.
