A violência na análise do contexto das escolas públicas: evidências da rede estadual de ensino de Minas Gerais
Authors: Anjos Couto André Augusto , Soares José Francisco
Published: April 2019

A violência é um fenômeno presente na realidade escolar brasileira e para tanto deve ser considerada nas análises contextuais das escolas. O objetivo desse artigo é analisar os efeitos da violência como um fator presente no contexto escolar. São utilizados dados de 18.542 pessoas registradas em boletins de ocorrência gerados no entorno das escolas estaduais de Minas Gerais e de 3.655 escolas dessa rede. Os boletins de ocorrência forneceram informações sobre o tipo de crime, tipo de envolvimento (autor, coautor, suspeito e vitima), sexo, cor e faixa etária dos envolvidos nessas ocorrências. Com relação ao contexto escolar foram abordadas as características Nível Socioeconômico das escolas, Regularidade e Formação Docente, Complexidade da Gestão e Infraestrutura das escolas. Foram realizados procedimentos descritivos e de associação. Os resultados demonstraram um maior envolvimento nos crimes de pessoas pardas e as mulheres corresponderam ao maior número de vítimas. Observou-se uma prevalência maior na participação dos crimes de pessoas entre 11 e 17 anos. Evidenciou-se também que a baixa rotatividade, o menor nível socioeconômico, a baixa complexidade das escolas e pouca infraestrutura ocorrem conjuntamente com casos de violência no entorno. Quanto à formação docente os resultados apontaram que uma melhor formação não estava associada à baixa violência no entorno das escolas o que necessita de mais investigações.
İsmail Cerrahoğlu’nun Tâbiîn Dönemi Tefsiri ve İsrâiliyat Literatürüne Bakışının Analizi
Authors: KAYACAN Murat
Published: April 2019

Sahâbe
sonrası ilk dönemin İslam literatüründeki karşılığı tabiîn dönemidir (h.
65-135). Kronolojik olarak o dönemin risâlet dönemine yakınlığı, dönemin âlimlerinin
tefsire dair ortaya koydukları -çoğu zaman referans niteliğindeki- görüşleri
değerli kılmaktadır. Yine tefsirde akıl-nakil dengesinin akıl lehine değişmeye başladığının
izlerinin görüldüğü bu dönemde, başta Yahudilik olmak üzere diğer din ve
kültürlerin tefsirde etkisi artma eğilimine girmiştir. Tefsirde İsrâiliyat
kavramıyla ifade edilen bu literatüre eleştirel yaklaşanlar olduğu gibi topyekûn
karşı çıkanlar da vardır. Bu bağlamda araştırmanın konusu, Türkiye tefsir
çalışmalarında önemli bir yeri olan İsmail Cerrahoğlu’nun iki ciltlik Tefsir
Tarihi adlı eserinde tâbiîn dönemi tefsirine ve o dönemdeki İsrâiliyat’a
dair yaklaşımlarıdır. Cerrahoğlu, konuyu ele alırken dönemin tefsir ekolleri ve
önde gelen müfessirlerinden bazılarını da detaylı bir şekilde incelemektedir;
ancak o kısım, bu araştırmanın sınırlarını aşar düşüncesiyle kapsam dışında
tutulmuştur. Çalışmada, tâbiîn dönemi tefsiri ve İsrâiliyat literatürü doküman
analizi yöntemiyle ele alınırken araştırma konusunun kavranmasına katkı
sağlaması amacıyla sahâbe tefsiri ile tâbiîn tefsiri karşılaştırmalı olarak
ortaya konulacaktır.

Bangka Belitung : Patronage and Political Identity in a Plural Society
Authors: Ibrahim
Published: April 2019

This writing examines these patterns of political mobilization by focusing on three aspects of electoral dynamics. After a brief background section, the writing analyses, first, the varieties of patronage politics that candidates engaged in. This section notes that, although most candidates denied involvement in money politics, in fact patronage was central to most of their strategies, and they demonstrated great creativity in devising new forms of gifts and means of delivery. Second, the writing investigates the campaign structures used by candidates, noting a basic division between casual and unstructured methods used by poorly resourced candidates and more elaborate and effective structures built by wealthier candidates. Third, the chapter examines patterns of identity-based networking by the candidates. Here, we face something of a puzzle: though Bangka Belitung society is remarkably open and ethnically tolerant, candidates often relied on narrow identity appeals and networks when reaching out to voters.
Recovery from misinterpretations during online sentence processing
Authors: Blott Lena Maria , Rodd Jennifer M , Ferreira Fernanda , Warren Jane
Published: April 2019

Misinterpretations during language comprehension are common. The ability to recover from such processing difficulties is therefore crucial for successful day-to-day communication. The present study investigated the outcome of comprehension processes and on-line reading behaviour when misinterpretations occurred. Although group-level effects of reinterpretation on sentence comprehension and on-line processing are of great theoretical interest, individual differences in the recovery from processing difficulty are of particular practical relevance. Even adult readers vary considerably in their “lexical expertise”, their knowledge of word forms and meanings and their experience with written material. We therefore also investigated the effect of individual differences in lexical expertise on processes related to the recovery from misinterpretations. Ninety-six adult participants read “garden-path” sentences in which an ambiguous word was disambiguated towards an unexpected meaning (e.g. The ball was crowded), while their eye movements were monitored. A Meaning Coherence Judgement task additionally required them to decide whether or not each sentence made sense. Results suggested that readers did not always engage in reinterpretation processes but instead followed a “good enough” processing strategy. Successful detection of a violation to sentence coherence and associated reinterpretation processes also required additional processing time compared to sentences that did not induce a misinterpretation. Although these reinterpretation-related processing costs were relatively stable across individuals, there was some evidence to suggest that readers with greater lexical expertise benefited from greater sensitivity to the disambiguating information, and were able to flexibly adapt their on-line reading behaviour to recover from misinterpretations more efficiently.
Good things come to those who wait: Delaying gratification likely does matter for later achievement
Authors: Doebel Sabine
Published: April 2019

A seminal finding in psychology is that children who delay gratification by waiting for two marshmallows instead of eating one right away fare better later in life (Shoda, Mischel, & Peake, 1990). However, a recent conceptual replication suggests that this original finding is not robust to the inclusion of covariates (Watts, Duncan, and Quan, 2018). Drawing on theory and evidence, we argue that Watts et al.’s analyses may have removed the very relationship of interest by controlling for fundamental processes supporting delay of gratification that indeed are likely targets of interventions. Thus, we suggest their results may be best construed as a (much needed) partial replication of the original work, and that the effectiveness of interventions targeting delay of gratification can be explored in future studies.
The Time Course of Responding to Aversiveness in Females with a History of Non- Suicidal Self-Injury
Authors: Funkhouser Carter J.
Published: April 2019

Non-suicidal self-injury is a risk factor for suicidal behavior, particularly in females. Twoprominent theories of suicide suggest that habituation to the psychophysiological aversiveness of NSSI is a mechanism by which NSSI exposure may lead to increased risk for suicide. Several laboratory studies examining the relationship between physiological habituation and suicide attempt history have yielded mixed results, potentially due to their use of broad measures of physiological arousal and/or focus on specific psychopathologies. However, no studies have examined the association between the time course (e.g., habituation, initial reactivity) of responding to aversiveness and NSSI, which may help to elucidate psychophysiological mechanisms of NSSI. Therefore, we examined habituation and initial reactivity to aversiveness (indexed by the time course of acoustic startle reflex, a well-validated measure of defensive responding) in three groups of young adult females – those with a history of NSSI, psychiatric controls matched on potential confounds (e.g., psychopathology, trauma history, demographics), and healthy controls. Results indicated that individuals with a history of NSSI exhibited blunted initial reactivity and marginally slower habituation to aversiveness relative to the two control groups. The NSSI group’s insensitivity to aversiveness may reflect prior psychophysiological habituation, and may be a mechanism through which prior NSSI exposure leads to increased riskfor suicidal behavior.
Expressions of doubt and trust in online user reviews
Authors: Evans Anthony M , Stavrova Olga , Rosenbusch Hannes
Published: April 2019

How do expressions of doubt affect trust in online reviews? Previous research leads to conflicting predictions: some studies find that people trust confident advisors more than doubtful advisors, whereas others find doubtful advisors are trusted more, especially when advisors have salient conflicts-of-interest. We tested the effects of doubt in the Yelp Open Dataset (N = 5.9 million user reviews). Reviews were coded using the Linguistic Inquiry Word Count (LIWC) software, which contains two dictionaries related to doubt, tentativeness and (lack of) certainty. Doubtful reviews were more likely to be seen as useful, and this result was robust when controlling for other psychological variables, as well as review length and linguistic complexity. The beneficial consequences of expressing doubt were strongest for positive (5-star) reviews, suggesting that doubt may mitigate concerns about the veracity of overly positive reviews. The present study emphasizes the advantages of expressing doubt.
Prospective randomized controlled trial comparing the functional outcome of olecranon osteotomy versus triceps tongue elevation for surgical exposure of distal humerus in adults
Authors: Rajak Asish , Maharjan Rajiv , Shrestha Bikram Prasad , Chaudhary Pashupati , Kalawar Rosan PS
Published: April 2019

Background: Fractures of the distal end of the humerus are difficult to treat. The goal of treatment is to achieve a stable, painless elbow with early adequate range of motion. They are operated mainly by posterior approach among which olecranon osteotomy (bony component violation) and triceps tongue elevation (soft tissue component breach) were used in this study.

Objectives: The aim of this study was to compare olecranon osteotomy and triceps tongue elevation in terms of functional outcome (Mayo elbow performance index), rates of complications and others.

Methodology: A randomized control trial was conducted including 39 eligible adults (20 in triceps tongue elevation and 19 in olecranon osteotomy group) presenting to B.P. Koirala Institute of Health Sciences during the study period of 12 months duration. All skeletally mature adult patients with isolated traumatic closed intra-articular or distal end fracture of humerus without distal neurovascular deficit were included. Patients with polytrauma, refractures, compartment syndrome and patient not giving consent were excluded from the study. They were operated and followed up at 2, 6, 12 and 24 weeks.

Results: The demographic profiles of the two groups were comparable. There was significant difference between the intraoperative time between the two groups (p=0.009). At final follow up, there were no significant differences in functional outcome and complications.

Conclusion: The approaches are comparable in terms of union, post-operative function and complications. There was increased intraoperative time in the olecranon osteotomy approach suggesting that patients who cannot tolerate longer intraoperative time may benefit from triceps tongue elevation approach.
Bronchoscopy and fine needle aspiration cytology aided diagnosis of suspected lung malignancy- A prospective observational study
Authors: Pant Subash , Shrestha Sanjeet Krishna , Sharma Lucky , Mahaseth Rinky , Neopane Arpana
Published: April 2019

Background: Flexible bronchoscopy is the main modality of diagnosing lung malignancy as per the location of lesion in our setup. Accurate diagnosis and categorization into various types is vital for its prognostic and management point of view.

Objectives: The study was conducted to find out yield of bronchoscopy and FNAC in suspected lung lesion and to know the various subtypes of bronchogenic carcinoma.

Methodology: The study was conducted in Kathmandu Medical College Teaching Hospital from December 2016 to May 2018. This was a prospective observational study conducted in 90 radiological suspected lung lesions. Radiological, bronchoscopy, histopathological and cytopathological findings were analyzed and evaluated. Data were recorded on a pre-designed proforma and entered into Statistical Package for the Social Sciences version 20.

Results: Among 90 suspected lung lesions who underwent contrast enhanced computed tomography, chest mass lesion was seen in 57(63.3%) subjects, nodular in 8 (8.9%), consolidation in 7 (7.8%), fibrosis in 7 (7.8%), collapse in 6 (6.7%) and pleural effusion in 3 (3. 3%).The most common malignancy was squamous cell carcinoma (53.48%). Lung malignancy was more common among endobronchial growth. The tendency of lesion to be malignant however tended to be significant at right upper lobe (p=0.02). When the suspected lesion was mass, the occurrence of malignancy was significantly higher (p<0.05).

Conclusion: The diagnostic yield increases with presence of right upper lesion with endobronchial growth. When the lung lesion presents as mass, the yield of having malignancy is also higher.
The Intersemiosis of Negative Emotions in the Cinematic Discourse: a Psycholinguistic Perspective
Authors: Krysanova Tetiana , Shevchenko Iryna
Published: April 2019

This study of the psycholinguistic properties of negative emotions in the English cinematic feature discourse focuses on the establishment of their intersemiosis – the simultaneous multimodal construction of emotional meanings by means of heterogeneous sign systems. The means of meaning construction in the cinematic discourse include linguistic, non-linguistic (prosody, kinesics, etc.) and extra-linguistic (music and kineikonic means), and different modes – acoustic and visual channels for transmitting meanings. The main psycholinguistic properties of cinematic emotions are their inextricable connection with the physiological processes, rootedness in the common human embodied experience, motivational basis; emotions are read as the result of an assessment of the satisfaction degree of individuals’ needs. The construction of emotional meanings in the cinematic discourse is the result of the interaction between the real world of the film makers and the imaginary world of the action. In constructing negative emotional meanings in general and emotions of fear and anger, in particular, the collective author of the cinematic discourse uses different semiotic codes in a parity or non-parity way. In the first case, heterogeneous semiotic codes both serve to denote fear or anger, while in the second, advantage is given to one of heterogeneous codes – linguistic, non- linguistic, and extra-linguistic. Consequently, this leads to the domination of one of the modes of transmitting meanings to the collective viewer – acoustic or visual. According to the coherence parameter of the emotional meaning embodied by various means of the semiosis of fear or anger, individual episodes of the English cinematic feature discourse are either congruent or non-congruent. Being congruent, different codes simultaneously transmit the same emotional meaning; being incongruent, heterogeneous semiotic codes actualize different emotional meanings, which leads to higher expressiveness of such emotions and their more effective influence on the viewer.
Hemispheric Organization of Visual Word Recognition in Turkish Monolinguals
Authors: Mergen Filiz , Kuruoglu Gulmira
Published: April 2019

Recently obtained data from interdisciplinary research has expanded our knowledge on the relationship between language and the brain considerably. Numerous aspects of language have been the subject of research. Visual word recognition is a temporal process which starts with recognizing the physical features of words and matching them with potential candidates in the mental lexicon. Word frequency plays a significant role in this process. Other factors are the similarities in spelling and pronunciation, and whether words have meanings or are simply letter strings. The emotional load of the words is another factor that deserves a closer inspection as an overwhelming amount of evidence supports the privileged status of emotions both in verbal and nonverbal tasks. It is well-established that lexical processing is handled by the involvement of the brain hemispheres to varying degrees, and that the left hemisphere has greater involvement in verbal tasks as compared to the right hemisphere. Also, the emotional load of the verbal stimuli affects the specialized roles of the brain hemispheres in lexical processing.
Despite the abundance of research on processing of words that belong to languages from a variety of language families, the number of studies that investigated Turkish, a language of Uralic-Altaic origin, is scarce. This study aims to fill the gap in the literature by reporting evidence on how Turkish words with and without emotional load are processed and represented in the brain. We employed a visual hemifield paradigm and a lexical decision task. The participants were instructed to decide if the letter strings presented either from the right or the left of the computer screen were real words or non-words. Their response times and accuracy of their answers were recorded. We obtained shorter response times and higher accuracy rates for real words than non-words as reported in the majority of studies in the literature. We also found that the emotional load modulated the recognition of words, supporting the results in the literature. Finally, our results are in line with the view of left hemispheric superiority in lexical processing in monolingual speakers.

Authors: Ebrahimnejad Gorji K , Abedi Firouzjah R , Khanzadeh F , Abdi-Goushbolagh N , Banaei A , Ataei Gh
Published: April 2019

Introduction: In this study, organ radiation doses were calculated for the renal agent 99mTc-DTPA in children. Bio-kinetic energy of 99mTc-DTPA was evaluated by scintigraphy and estimates for absorbed radiation dose were provided using standard medical internal radiation dosimetry (MIRD) techniques.Materials and Methods: In this applied research, fourteen children patients (6 males and 8 females) were imaged using a series of planar and SPECT images after injecting with technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA). A hybrid planar/SPECT method was used to plot time-activity curves to obtain the residence time of the source organs and also MIRDOSE software was used to calculate the absorbed dose of every organ. P-values were calculated using t-tests in order to make a comparison between the adsorbed doses of male and female groups.Results: Mean absorbed doses (µGy/MBq) for urinary bladder wall, kidneys, gonads, liver and adrenals were 213.5±47.8, 12.97±6.23, 12.0±2.5, 4.29±1.47, and 3.31±0.96, respectively. Furthermore, the mean effective dose was 17.5±3.7 µSv/MBq. There was not any significant difference in the mean absorbed dose of the two groups.Conclusion: Bladder cumulated activity was the most contribution in the effective dose of patients scanned with 99mTc-DTPA. Using a hybrid planar/SPECT method can cause an increase in accumulated activity accuracy for the region of interest. Moreover, patient-specified internal dosimetry is recommended.

Published: April 2019

This study analyzed the association between household employment and household poverty using logit regression on survey data of Multan District. It is found that qualification of household head, gender of household head, household employment rate, number of males employed in formal sector, number of females employed in informal sector, females permitted to paid work outside home, female’s autonomy to utilize household resources, possession of agricultural land, residence, possession of livestock and government health facility in household’s vicinity have significantly negative impact on probability of household’s poverty. Household size and number of children (≤ 5 years) are positively associated with household poverty. It is suggested that empowering women and creating productive employment opportunities in both formal and informal sectors may help to reduce poverty..

Authors: Aguilar Cucurachi María del Socorro , Merçon Juliana , Silva Rivera Evodia
Published: April 2019

Entender cómo los grupos humanos le dan significado a la naturaleza y cómo es su relación con los ecosistemas, constituye la principal preocupación en el estudio de las percepciones ambientales. Conocer las percepciones puede favorecer esfuerzos educativos para la conservación de las especies y de los ecosistemas. Con el objetivo de analizar las percepciones sobre los primates, les pedimos a niños y niñas de tres escuelas primarias rurales de Tabasco, México, que dibujaran cómo viven los monos, qué comen y cuáles son los problemas o amenazas que enfrentan para sobrevivir en sus comunidades. Desde un enfoque metodológico mixto, interpretamos el contenido de 197 dibujos de 110 niñas y 87 niños de cinco a doce años de edad. Asignamos categorías de análisis relacionadas con la percepción de las especies de primates, su entorno y las amenazas que enfrentan. Aplicamos análisis de varianza (ANOVA) de dos vías para comparar las percepciones entre comunidades y el test de G para comparar género. Los resultados indican que las percepciones se construyen a partir de los contextos de las comunidades y que éstas ofrecen elementos para una mejor comprensión de los procesos socioecológicos. En el marco educativo, consideramos que este estudio permite articular al menos tres dimensiones: cognitiva, cultural y política, en las que la dimensión ecológica tiene un papel transversal.

Authors: García Flores José Carmen , Gutiérrez Cedillo Jesús Gastón , Araújo Santana María Raimunda
Published: April 2019

El objetivo del artículo fue analizar los factores sociales que propician la riqueza vegetal en huertos familiares de tres localidades rurales del Estado de México. El enfoque teórico de estrategia de vida se utilizó para indagar las acciones realizadas por las personas de ingresos bajos en dichas localidades. La metodología consistió en: selección y caracterización del área de estudio; descripción de las familias y los huertos familiares; análisis del manejo de los agroecosistemas, la riqueza de especies y su aprovechamiento; y exploración de factores sociales asociados a la riqueza vegetal. Los resultados revelaron una riqueza de especies alta, se registraron 128 especies en las tres localidades, usadas para fines variados. Los valores del índice de Simpson D indicaron que la diversidad de especies en los huertos familiares es baja (> 0.9). La familia se distribuye las prácticas de manejo, mismas que involucran creencias, costumbres y tradiciones locales. Los factores que favorecen la riqueza vegetal fueron la religión, la ocupación y el valor de uso del huerto familiar. Se concluye que los factores sociales identificados propician la agrobiodiversidad, influyendo en la estrategia de vida de huertos familiares.

Published: April 2019

El turismo en espacios naturales es un fenómeno que se intensificó en las últimas décadas. El objetivo de este trabajo es identificar los impactos de esta actividad en los Parques Nacionales Sierra de San Pedro Mártir y Constitución de 1857. Para ello, se realizó observación directa y 18 entrevistas semiestructuradas a funcionarios y habitantes de las áreas de estudio. Entre los resultados más sobresalientes se identificaron los impactos al medio natural y la interacción entre funcionarios, habitantes locales y turistas, así como las diferencias y similitudes de los impactos entre ambos parques. Para las dos áreas de estudio se sugiere prestar atención en los impactos ecológicos, dado que los programas de desarrollo estatal promueven aumentar el número de visitantes en los parques sin considerar los daños que esto puede representar en sus ecosistemas. Hay escasos estudios a nivel nacional que abarquen aspectos sociales y económicos del turismo en áreas naturales, por ello se recomienda trabajar más en estos ámbitos.

Published: April 2019

El trabajo retoma al ecofeminismo de la subsistencia para conocer la participación de las mujeres en la conservación de los maíces nativos a través de la elaboración y venta de tortillas artesanales. Es un estudio etnográfico feminista que pretende dar visibilidad a las relaciones de género que resultan en negociaciones entre mujeres y hombres que sostienen la continuidad alimentaria maíz-tortillas artesanales. Para ello se llevaron a cabo tres tipos de entrevistas (a profundidad, semiestructuradas y estructuradas) a mujeres y hombres ≥ 18 de años de edad, que participan en actividades relacionadas con la continuidad alimentaria maíz-tortillas artesanales en el mercado La Placita de Ixtlahuaca, Estado de México. Los resultados se agruparon en tres tipos de actores/as: mujeres que elaboran y venden tortillas artesanales, productores/as de maíces nativos y consumidores/as de tortillas. Se discuten las negociaciones entre grupos, así como la influencia de factores externos como la siembra de maíces mejorados y el acceso a maíz nativo. Se concluye que la permanencia de los maíces nativos se debe a las relaciones y negociaciones que articulan las mujeres que elaboran y venden tortillas entre productores/as y consumidores/as, vinculadas a las estrategias de subsistencia.
The late pleistocene deposits and the small mammals’ fauna of the Middle Palaeolithic site Betovo (Desna River basin)
Authors: Voskresenskaya E. V. , Markova A. K.
Published: April 2019

The Middle Palaeolithic site Betovo was discovered in the early 1970s by L.M. Tarasov, who summarized data on paleoecology and habitat conditions on this site in a number of publications. However, the stratigraphic position of the deposits containing the cultural layer remained rather uncertain due to the fact that in the sections of the site it was not possible to identify the reference loess-soil horizons and data on the age of the cultural layer were not obtained. A comprehensive study of the site, renewed since 2007 under the direction of archaeologist A. K. Ocherednoi in the frame of the Verkhnyaya Desna expedition of the Institute for the History of Material Culture RAS, permit to detail the deposition rhythmic during the Late Pleistocene and the stratigraphic position of the cultural layers in different parts of the site. By received 14 C data, the site was inhabited in the range of 28.5–36.0 cal kyr BP (calibrated dates), i.e., belongs to the end of the Valdai megainterstadial (the end of MIS 3). The small mammal fauna found in the 2 cultural layer of the Betovo site includes only the tundra and steppe species. The forest species are absent. The species richness of the Betovo fauna is very low, what also indicates the very severe climate during the end of MIS 3 in the Desna River basin. The received mammalian data clearly indicate the extremely harsh natural-climatic conditions of the time of habitation of the ancient man in the site – the conditions of tundra-steppe (“mammoth steppe”).
Organic matter and mineralization of river waters in mountains of Russia and adjacent countries
Authors: Smirnov M. P.
Published: April 2019

The article examines general regularities of the formation of dissolved organic matter (DOM), salinity (∑), the acid-alkaline indicators (pH) river waters in the mountains with various types of altitudinal zonation in Russia and CIS countries. The analysis is based on the results of many years of experimental studies in the network of the Roshydromet. The reaction of water of rivers in a southerly direction in accordance with changes in landscape-geochemical conditions are sequentially changed from acidic in the tundra of the Arctic to neutral in the tundra and taiga, slightly alkaline in forest-meadow and alkaline in a desert and subtropical mountains. The average annual salinity water of the mountain rivers in two Northern types of vertical zones is 42 and 74 mg/l, in two Southern types – 140 and 450 mg/l. The average annual values of permanganate (PO) and bichromate (BO) oxidation, and color of river water in xerophytic desert-subtropical mountains are small (3 and 7), and increase to medium and slightly increased grades into humid tundra and taiga, tundra of the Arctic, and the forest meadow mountains (7–8 and 13–18 mg O/l). Relationships PO:BO change from 62% in the tundra of the Arctic up to 50%, 41% and 35% in the tundra and taiga, forest-meadow and desert-subtropical mountains. The content of humic (HA) and fulvic (FA) acids is also maximum in two Northern types of vertical zones (0.224 and 1.80 mg/l) and decreases in the two Southern types to 0.013 and 0.067, 0.373 and 0.637 mg/l. The relationship of contents of HA and FA decreases to the South in forest-grassland and desert-subtropical mountains in 1.3 and 3.7 times.

The subject of the study in the article is the growing need for the use of spatial information for efficient agricultural production, due to the growing tendency of Earth remote sensing data accessibility, which, due to the spatial and temporal resolution improvement, can be used in the land cover analysis and other related jobs. The goal is to review the obtaining process of satellite multispectral space imagery from Sentinel-2 and to consider the possibility of their use for monitoring crops during the entire vegetation phase. The tasks: to study the modern needs of agricultural producers in the field of analysis of land cover occupied by agricultural crops; the analysis of the European Space Agency programs and the global land program Copernicus, which uses spatial information from Sentinel-2 for use in the agricultural sector; estimation of the constellation characteristics of Sentinel-2, imaging equipment and remote sensing data processing results by ground services received from Internet services; the use of Sentinel-2 multispectral space imagery for monitoring crops during the entire vegetation phase. The following results were obtained. After analyzing agricultural producers needs and the European Space Agency program, the feasibility of using multispectral space images taken by the Multispectral Instrument installed on satellites Sentinel-2 was established. Free access to the space imagery database is provided through the Copernicus Open Access Hub Internet Service. For the researched territory, Poltava region, Chutov district, the village of Vilkhovatka, various time space images were obtained and the normalized difference vegetation index (NDVI) was calculated. Histogram analysis of the obtained vegetation index values distribution within a single field (corn to grain) allows to reveal a quantitative and qualitative change in biomass, indicating a change in the vegetative phase. Conclusions. The approach described in this paper allows to conduct monitoring of the cropping state during the vegetation phase using both qualitative – visual analysis and quantitative – NDVI index, criteria. The change in the values of the normalized difference vegetation index can reveal a change in the biomass state. However, for calculating the NDVI index, data from near-infrared and red channels is needed, which complicates the acquisition of the original image. Therefore, in order to obtain the quantitative criteria in subsequent jobs, it is expedient to consider the possibility of using fractal dimension, which will reduce the amount of input data required for calculations.
Subcloning, expression and purification of Human Hialuronidase-1, variant 8.
Authors: Del Monaco Adriana , Hirata Mario H
Published: April 2019

Hyaluronic Acid, HA is a major component of the extracellular matrix of vertebrates. It is a glycosaminoglycan hydrolyzed by enzymes of the hyaluronidase family, involved in the regulation of important biological processes such as angiogenesis and vascular permeability. As interest in the development of a synthesis route for this enzyme, we aim to obtain a plasmid containing the coding sequence of gene variant 8 Hyal-1. To obtain the plasmid insert was planned and two restriction sites for sub-cloning site directed at the 5 'Bam H-1' and 3 'Not-1 in codon sequence of Hyal-1. The insert was sub-cloned into plasmid pET28-a, and transfected for expression in Escherichia coli Bl-21. The expression was induced by IPTG in best time of 4 hours and confirmation of protein expression was performed by Western blotting. There was a 45 kDa protein, thus confirming the presence of Hyal-1. Purification was performed on nickel agarose column to obtain a larger amount of the protein, approximately 25μg/L. The route suggested in this study was efficient attainment of Hyal-1 recombinant protein.

La Mejora de la Regulación: antecedentes y principios
Authors: Míguez Macho Luis
Published: April 2019

Las políticas de mejora de la regulación son una consecuencia de la reflexión generada después de los grandes procesos de liberalización de la economía de los años ochenta y noventa del siglo pasado sobre la inevitabilidad de la intervención pública en aquella, es decir, de la regulación, pero al mismo tiempo sobre la necesidad de que la misma se lleve a cabo correctamente, para no imponer cargas administrativas excesivas a los ciudadanos y a las empresas que mermen la competitividad del sistema económico y, en último término, restrinjan de manera injustificada la libertad. Principios como los de la previsibilidad de las normas, la participación ciudadana en su elaboración o la proporcionalidad son algunas de las bases de estas políticas.
