Abstract
To study the compositional trends of rare earth elements (REEs: La, Ce, Nd, Sm, Eu, Tb, Dy, Yb, Lu), Th and U in soil samples collected from a site for a potential coal based power plant as well as to conduct a preliminary assessment of environmental impact of the proposed power plant in terms of REEs, Th and U, we have analyzed nine soil samples by instrumental neutron activation analysis. Evaluation of data quality by repeated analysis of IAEA-Soil-7 and IAEA-SL-1 ensures a proper data base-line for the REEs, Th and U abundances of the sampling site. Chondrite-normalized abundance patterns demonstrate the heavy REEs–light rare earth elements and Th–U fractionations in our sample suite along with significant negative Eu anomaly. Thorium/U ratio in our study area ranges from 4.55 to 6.07 which is higher than that of upper continental crust. Preliminary assessment of environmental impact of the proposed power plant is evaluated by taking NIST-SRM-1633b (coal-fly-ash) as contaminant as coal-fly-ash will be the major byproduct of the power plant. Previous literature studies and our prevailing data invoke that proposed power plant will have no severe impact on soil originated biota and on human health in terms of REEs, Th and U abundances. However, the long term effect of excessive REEs, Th and U as well as the other elemental abundances originating from coal-fly-ash should also be taken into an account.
Producer organizations and contract farming: a comparative study of smallholders’ market strategies in South India
Authors: Gersch Inka 
Published: January 2018

Abstract
The fundamental restructuring processes of agri-food networks in developing and emerging markets have intensified the debate on how to improve the integration of smallholders into so called modern value chains. In this context, the company-driven contract farming model and the member-based model of producer organizations are discussed by practitioners and in the scholarly literature as alternatives to traditional market systems. This study compares the models’ abilities to address economic challenges of highly fragmented and small-scale dominated agriculture on a household as well as on an aggregate level. It analyzes empirical data from the Indian floriculture sector with the global value chain approach. The study reveals that the smallholders perceive both contract farming and producer organization to be beneficial for their households’ economic risk situation, while only the producer organization has a positive effect on the households’ income. The contract farming benefits production and value chain efficiency, whereas the producer organization does not show an impact in these respects. We thus observe that the contract farming model increases value creation in the overall chain, but it does not raise the producer’s value capture; while the producer organization model does not heighten value creation in the overall chain, but it lifts the producers’ value capture. The organization’s individual capabilities determine how each model addresses the economic challenges. Overall, the author argues that contract farming and producer organizations are supplementing, not competitive, strategies and should be applied in combination.

ObjectiveTo evaluate the response of bone to chronic long-term growth hormone (GH) and insulin-like growth factor-1 (IGF1) excess by measuring the expression of selected mRNA and microRNA (miR) in bone tissue samples of patients with active acromegaly.DesignCase–control study.MethodsBone tissue samples were obtained during transsphenoidal adenomectomy from the sphenoid bone (sella turcica) from 14 patients with clinically and biochemically confirmed acromegaly and 10 patients with clinically non-functioning pituitary adenoma (NFPA) matched by sex and age. Expression of genes involved in the regulation of bone remodeling was studied using quantitative polymerase chain reaction (qPCR).ResultsOf the genes involved in osteoblast and osteoclast activity, only alkaline phosphatase (ALP) mRNA was 50% downregulated in patients with acromegaly. GH excess caused increased expression of the Wnt signaling antagonists (DKK1)and agonists (WNT10B)and changes in the levels of miR involved in mesenchymal stem cell commitment to chondrocytes (miR-199a-5p) or adipocytes (miR-27-5p, miR-125b-5p, miR-34a-5p, miR-188-3p)P < 0.05;q < 0.1. Relevant compensatory mechanisms were found through the changes in miR involved in osteoblastogenesis (miR-210-5p, miR-135a-5p, miR-211, miR-23a-3p, miR-204-5p), but the expression of TWIST1 was 50% downregulated and RUNX2 was unchanged.ConclusionsAcromegaly had minimal effects on tested mRNAs specific to osteoblast or osteoclast function except for downregulated ALP expression. The expressions of miR known to be involved in mesenchymal stem cell commitment and downregulated TWIST1 expression suggest acromegaly has a negative effect on osteoblastogenesis.

<p>During 2005-2015 we conducted the research on the success of laying eggs in 82 species of birds nesting in the island oak and hornbeam forests of the region. 1095 cases of reproduction have been studied. The value of the masonry of each species has changed. 197 clutches (18%) out of 1095 are unfinished (we consider masonry to be unfinished if it consists of 50% or fewer eggs comparing with medium masonry). Very often unfinished masonry or even empty abandoned nests are observed in birds nesting on the ground. The anthropic factors are among the reasons preventing the end of the clutches. They are: grazing, sanitary felling, picking berries and mushrooms, visiting the forest lands for walks, etc. A significant part of the nests was left due to the death of one of the partners from predators or destroying the incipient clutches. The success of birds’ reproduction also reduces masonry or broods and the last ones die. This factor is also mentioned by A.S. Giliazov (1981). Due to the reproduction success, all 82 species of birds are divided into 7 groups with 10% interval between them. The highest success of nesting is observed in sedentary species (on average – 62.23%), and the lowest - in migratory species (on average – 54.03%). This indicates the better fitness of sedentary species to unfavourable weather conditions overcoming, stronger ecological plasticity in general, including all periods of their life cycle including reproduction.</p>

<p>There has been the impact on the corn silage harvesting and the influence of the corn silage store technology of the microbial inoculants studied. The main advantages and the prospects of the silage inoculants using were outlined. This has been the supplements of microorganism’s inhibition impact on the molds and the fungi development established. Thereby, this was possible to provide the initial properties of raw materials preservation. The use of the 11C33 inoculants at a dose of1 gramper 1 tone of the silage during the storage period provides the dry matter reduction at a rate of 6.9 % versus 14.9 % in comparison with the control group respectively. According to the requirements of the GOST 4782:2007 and the results of the biochemical silage studies the harvested feed without the inoculants using can be classified as the 3rd class. However, the treated silage with the 11C33 inoculant can be classified as the 1st class. The biological conservant inoculation during the milky-wax stage of ripeness helps the feed nutrients to have the better preservation. And the corn silage feeding as a part of its ration is likely to increase the average bulls daily weight gain for the feed costs production reduction. The microbial inoculants using during the corn silage harvesting helped to reduce the feed costs with the1 kgof the bull’s live weight gain by 6.07 %. We found that the preslaughter live weight at the age of 15 months was characterized by bulls of the trial group of the Ukrainian black and white milk breed and they were raised on the corn silage with the microbial inoculants. These bulls showed the better results comparing to the control group by 4.3 % (P&lt;0.05) and the bull’s carcass yield of the trial group was higher than the control one, and it was 56.4 %.</p>

<p>The article is devoted to study of the biological activity of soil under sweet corn crops depending on tillage depth, mineral fertilizers application rate with drip irrigation in the soil-ecological conditions of the Dry Steppe Zone of Ukraine. The plan of the experiment foresaw study of such factors: A — tillage depth (moldboard plowing on 20-22 and 28-30 cm); B — mineral fertilizers application rate (no fertilizers, N<sub>60</sub>P<sub>60</sub>, N<sub>120</sub>P<sub>120</sub>); C — plants density (35, 50, 65, 80 plants ha<sup>-1</sup>). We used water of the Ingulets irrigation system for irrigation. The water belongs to II quality class by agronomical criteria of the DSTU 2730-94 and its suitability for irrigation is limited. We studied the soil biological activity on variants with 65 plants ha<sup>-1 </sup>by the indicies of its respiration rate (method of V.I. Shtatnov) and linen decomposition degree (“application” method). At the same time we have made monitoring of the soil meliorative state depending on the moldboard plowing depth by the toxic salts content, anionic-cationic composition of the aqueous soil extract. The results of the laboratory-field experiments prove that the moldboard plowing depth , mineral fertilizers application rates and soil meliorative state have an influence on its biological activity. The maximum respiration rate, which is used to characterize an activity of the aerobic microflora of the upper soil layers, was at moldboard plowing on depth of 20-22 cm at non-fertilized experimental variant — 250.0 mg СО<sub>2</sub>/m<sup>2</sup>×hour. Increase of the tillage depth and mineral fertilizers application rate significantly decreased carbonic acid emission to the athmosphere, which was the minimum of 178.3 mg СО<sub>2</sub>/m<sup>2</sup>×h. The maximum linen decomposition degree, which is used to characterize an activity of the cellulose-decomposing soil microflora, was at moldboard plowing depth of 28-30 cm at non-fertilized experimental variant — 58.3%. The tillage depth changed cellulose-decomposing soil microflora activity insignificantly. Mineral fertilizers application at the maximum rate of N<sub>120</sub>P<sub>120</sub>decreased cellulose-decomposing soil biota activity 1.7 times comparatively to non-fertilized variant. Higher toxic salts concentration (at 0.006-0.019 %), sodium ions content (at 0.15-0.38 mg-eq/100 g of soil) in the 0-50 cm layer led to decrease of the soil biological activity. We consider, that the best from the agroecological point of view is the variant with moldboard plowing depth of 28-30 cm, mineral fertilizers application rate N<sub>120</sub>P<sub>120</sub>.</p>

El efecto peanuts en la toma de decisiones intertemporales.
Authors: Cruz Rambaud Salvador , Sánchez Pérez Ana María 
Published: January 2018

La elección intertemporal hace referencia a la toma de decisiones individuales cuando se analizan las preferencias entre dos recompensas disponibles en distintos momentos del tiempo. Es decir, trata de analizar la preferencia o la indiferencia entre dos recompensas (x1,t1) y (x2,t2), donde x1<x2 y t1<t2 (Cruz et al., 2016). El modelo tradicionalmente utilizado para describir el comportamiento individual es el modelo de utilidad descontada (Samuelson, 1937). Se trata de un modelo descuento exponencial que supone que las decisiones tomadas por los agentes son racionales y consistentes. Posteriores estudios empíricos han demostrado que el modelo de utilidad descontada debe ser corregido teniendo en cuenta las denominadas “anomalías en la elección intertemporal” para que este proceso pueda definir adecuadamente el comportamiento de los agentes. Algunas de las anomalías más conocidas son el efecto plazo, el efecto magnitud, el efecto signo, el efecto secuencia y el efecto diseminación. No obstante, una anomalía que, hasta el momento, no ha sido abordada en profundidad y que merece especial consideración es el denominado efecto peanuts. Esta anomalía considera que la aversión al riesgo aumenta para grandes recompensas, estando los individuos más dispuestos a tomar mayores riesgos cuando la cantidad en juego es menor (Weber y Chapman, 2005). La propensión a tomar decisiones arriesgadas cuando está en juego una recompensa con un montante pequeño se explica, en parte, porque la anticipación de la emoción negativa de decepción es menor que aquélla que se produce cuando el valor de la recompensa esperada es mayor. De esta manera, el sujeto decisor es más propenso al riesgo ante recompensas pequeñas y/o poco probables, donde esta emoción negativa no está presente o es más débil. En este trabajo, se presenta un análisis del efecto peanuts a través de una revisión de la literatura así como de su tratamiento matemático. El presente trabajo ha sido financiado por el proyecto: “La Sostenibilidad del Sistema Nacional de Salud: Reformas, Estrategias y Propuestas” (referencia: DER2016-76053-R).

Este proyecto de investigación en el ámbito del Doctorado en Psicología, pretende analizar la importancia del entrenamiento de la autoeficacia (variable independiente) para el tratamiento de la dependencia alcohólica, observable en el mantenimiento en tratamiento y en la modificación / elevación de la calidad de vida, el objetivo último de la intervención y la medida de su eficacia (variable dependiente).La muestra se compone de un total de 146 dependientes alcohólicos que iniciaron tratamiento en la UAC, 90 (61,6%) de los cuales abandonaron el tratamiento tras la fase de internamiento, 35 (24%) tras la primera consulta y 21 (14,4%) se mantuvieron en tratamiento. Los instrumentos utilizados han sido los siguientes: El Inventário de sintomas psicopatológicos, que es la versión portuguesa del Brief Symptom Inventory (BSI, Derogatis, 1982) adaptada y contrastada para la población portuguesa por Canavarro en 1996 (Canavarro, 1999). El Inventario clínico de autoconcepto (ICAC), es una escala de autoevaluación unidimensional que desarrolló por Adriano Vaz Serra en 1985, El World Health Organization Cuality of Life, versión breve (WHOQOL-Bref) que se destina a la evaluación de la calidad de vida (Canavarro, Simões, Vaz Serra, Pereira, Rijo, Quartilho, Gameiro, Paredes, & Carona, 2007, p.77). Os resultados permitem concluir que la muestra se compone en su mayoría de individuos del sexo masculino (87%), indicándose que este aún es un problema asociado al género y 13% referente el género femenino. Este estudio fue delineado de forma que podamos comprender y aclarar cuáles la variable, más precisamente, la autoeficacia y la psicopatología interfieren en el tratamiento y en la QV del sujeto dependiente. Este estudio nos permitió validar algunas propuestas de la literatura y del tratamiento que subyace a la UAC. En este sentido concluimos que la autoeficacia fue la única variable del autoconcepto que se eleva de la primera fase de tratamiento para la segunda fase. Por lo tanto, concluimos con grado de certeza que la autoeficacia es una variable predictora del éxito del tratamiento así como de la elevación de la QV.

The present study aimed to examine the relationship between age range and vocabulary learning among pre-intermediate Iranian EFL learners. To this aim, 50 pre-intermediate Iranian EFL learners, male (N= 20) and female (N=30), were selected from a private language institute based on their performance on the Oxford Placement Test (OPT). They were divided into two groups: teenager and adult learners. Before intervention, a pretest of vocabulary was conducted to determine students’ vocabulary knowledge. Then, vocabularies were presentenced in dialog, word power and reading texts using a monolingual dictionary in five sessions interval for the both groups. After the intervention, a post-test of vocabulary was administered to examine the possible improvement. The data obtained from the administration of the pre-test and the post-test were analyzed using SPSS software. The results revealed that there was no significant relationship between the performance of teenager and adult groups in their vocabulary learning; and there was no significant difference between the performance of teenager and adult groups in their vocabulary learning. This research potentially has some implications that may help English language teachers, students, EFL learners and educational syllabus designers.
