Integrated modeling approach to the analysis of food security and sustainable rural developments: Ukrainian case study

In Ukraine, the growth of intensive agricultural enterprises with a focus on fast profits contributes considerably to food insecurity and increasing socio-economic and environmental risks. Ukraine has important natural and labor resources for effective rural development. For example, more than 50% of food production is still managed in small and medium farms despite the difficulties associated with economic instabilities and the lack of proper policy support. The main issue for the agro-policy nowadays is to use these resources in a sustainable way enforcing robust long term development of rural communities and agriculture. In this paper, we introduce a stochastic geographically explicit model for designing forward looking policies regarding robust resources allocation and composition of agricultural production enhancing food security and rural development. In particular, we investigate the role of investments into rural facilities to stabilize and enhance the performance of the agrofood sector in view of uncertainties and incomplete information. The security goals are introduced in the form of multidimensional risk indicators

Morphological estimation of changes in cancellous raduis bone for forensic age determination

Visual researches showed that the cancellous bone of the distal radius has significant morphological changes with the increase of years. Revealed structural changes of cancellous bone allows to differentiate the age of an object and to direct a medical expert towards the proposed age group at the identification study. As a result of photocolorimetric research of involution changes of cancellous bone of the distal radius we found statistically significant increase of light transmission with the increase of years which is associated with an increase of osteoporosis. The correlation coefficient ranged from 0,63 to 0,80. On the basis of these data mathematical models that allow to determine the person's age in the forensic identification researches of the distal radius were developed (standard mean square error in determination of the age was from 6,6 to 8,2 years)

Regularities of structural-cellular structure of ovaries in ontogenesis

The article presents the examination of the ovaries of embryos, ovaries of human feti and ovaries of children of the tender age. The researches revealed the increase of the surface of follicles, nucleus and primary oocyte's cytoplasm that tells about the fact that further follicular maturation continues in the ovaries of a child of 2-4 months old. Also we registered the increase of nuclear cytoplasmic ratio, appearance of single mature follicles with cumulus oophorus that testifies to the fact that the ovary is functionally mature. Furthermore the research revealed increased content of lipids and DNA in follicular epithelium that also tells aboutfunctional maturity of the ovary. It was found that incretory activity of an ovary during the first year of life is provided by the cells originated from the connective tissue membrane of atresic follicles

Label-free electrochemical monitoring of DNA ligase activity

This study presents a simple, label-free electrochemical technique for the monitoring of DNA ligase activity. DNA ligases are enzymes that catalyze joining of breaks in the backbone of DNA and are of significant scientific interest due to their essential nature in DNA metabolism and their importance to a range of molecular biological methodologies. The electrochemical behavior of DNA at mercury and some amalgam electrodes is strongly influenced by its backbone structure, allowing a perfect discrimination between DNA molecules containing or lacking free ends. This variation in electrochemical behavior has been utilized previously for a sensitive detection of DNA damage involving the sugar-phosphate backbone breakage. Here we show that the same principle can be utilized for monitoring of a reverse process, i.e., the repair of strand breaks by action of the DNA ligases. We demonstrate applications of the electrochemical technique for a distinction between ligatable and unligatable breaks in plasmid DNA using T4 DNA ligase, as well as for studies of the DNA backbone-joining activity in recombinant fragments of E. coli DNA ligase

Synthesis of Layered Organic-Inorganic Nanocomposites of Zinc and Copper by Laser Ablation in Liquid

The experimental data of studies of layered organic-inorganic nanocomposites (()-Zn(OH)2+DS) and (Cu2(OH)3+DS) which were produced in the result ablation of zinc and copper in aqueous solutions of surfactants—dodecyl sodium sulfate (SDS) and sodium bis-ethylhexyl succinate (AOT)—are presented. Dependence of the formation dynamics of these composites on an exposure time of radiation and on an aging time of colloids was studied by the absorption spectroscopy, by X-ray diffraction, by scanning electron (SEM), and atomic force microscopy (AFM). Composite (Cu2(OH)3+DS) with bilayered structure was produced by method of laser ablation of the copper metal target in liquid for the first time

The development and characteristics of a hand-held high power diode laser-based industrial tile grout removal and single-stage sealing system

As the field of laser materials processing becomes ever more diverse, the high power diode laser (HPDL) is now being regarded by many as the most applicable tool. The commercialisation of an industrial epoxy grout removal and single-stage ceramic tile grout sealing process is examined through the development of a hand-held HPDL device in this work. Further, an appraisal of the potential hazards associated with the use of the HPDL in an industrial environment and the solutions implemented to ensure that the system complies with the relevant safety standards are given. The paper describes the characteristics and feasibility of the industrial epoxy grout removal process. A minimum power density of approximately 3 kW/cm2 was found to exist, whilst the minimum interaction time, below which there was no removal of epoxy tile grout, was found to be approximately 0.5 s. The maximum theoretical removal rate that may be achievable was calculated as being 65.98 mm2/s for a circular 2 mm diameter beam with a power density of 3 kW/cm2 and a traverse speed of 42 mm/s. In addition, the characteristics of the single-stage ceramic tile grout sealing are outlined. The single-stage ceramic tile grout sealing process yielded crack and porosity free seals which were produced in normal atmospheric conditions. Tiles were successfully sealed with power densities as low as 550 W/cm2 and at rates of up to 420 mm/min. In terms of mechanical, physical and chemical characteristics, the single-stage ceramic tile grout was found to be far superior to the conventional epoxy tile grout and, in many instances, matched and occasionally surpassed that of the ceramic tiles themselves

The influence of comorbidity on the quality of life, the level of anxiety to therapy in patients suffering from nonspecific aortoarteritis

On the SigmaN cusp in the pp -> pK+Lambda reaction

Measurements of the $pp \to pK^+\Lambda$ reaction at $T_p$ = 2.28 GeV have been carried out at COSY-TOF. In addition to the $\Lambda p$ FSI and $N^*$ resonance excitation effects a pronounced narrow structure is observed in the Dalitz plot and in its projection on the $p\Lambda$-invariant mass. The structure appears at the $pp \to$N$K^+\Sigma$ threshold and is interpreted as $\Sigma$N cusp effect. The observed width of 20 MeV/$c^2$ is substantially broader than anticipated from previous inclusive measurements. Angular distributions of this cusp structure are shown to be dissimilar to those in the residual $pK^+\Lambda$ channel, but similar to those observed in the $pK^+\Sigma^0$ channel
