The correlation between the transthoracic lung ultrasound score (LUS) and the severity of changes in HRCTon patients with interstitial lung diseases Interstitial lung disease is a heterogeneous group of disorders. Chest high-resolution computed tomography is considered the "gold" standard radiological method for diagnosis of ILD. The objective of our study was to evaluate the correlation between the transthoracic ultrasound score and the severity of changes in HRCT simplified scores, the presence of symptoms and the pulmonary function impairment in patients with interstitial lungdisease(ILD). We have evaluated 58 consecutively patients diagnosed with ILD and compared with a non-healthy control group (n=30).Transtoracic lung ultrasound (LUS) total score was correlated with HRCT score (r=0.784, p<0.001) and chest positive areas (intercostal spaces with ≥5B-line) were correlated with HRCT score (r=0.805, p<0.005). Area under the receiver operating characteristic curve (ROC) for LUS total score using 5 as a HRCT score cut-off was 0.86 (p<0.001), respectively for positive chest areas with intercostal space with ≥5B-line was 0.88 (p<0.001). The sensitivity (Se) was 76.7%, the specificity (Sp) 92.9%. After dividing the ILD patients according to the HRCT pattern in usual interstitial pneumonia (UIP), non-specific interstitial pneumonia (NSIP) and other radiological interstitial abnormality we found a good correlation statistically significant only for first group (r=0.51, p=0.02). LUS had a positive correlation with age (r=0.481, p<0.001), negative correlation with DLCO (r=-0.39, p=0.007) and with alveolar volume (r=-0.39,p=0.007). The chest positive areas score was positive correlated with age (r=0.599, p<0.001), negative correlation with diffusing capacity of the lung for carbone monoxide (DLCO)( r=-0.44, p=0.002) andwiththealveolarvolume(r=-0.49,p=0.001).
Carbonic Anhydrase Activity Assay v1
Authors: C Koch Jack , Weis Virginia
Published: April 2019

Carbonic anhydrase (CA) is an enzyme which catalyzes the interconversion of bicarbonate ions (HCO3-) and carbon dioxide (CO2). The activity levels of CA can be measured by taking advantage of the chemical reaction that it catalyzes. When CO2 is added to a tissue homogenate, the CA present converts the CO2 into HCO3- and a hydrogen ion (H+), which results in a decrease in pH. The rate at which the pH drops can be measured and converted into a CA activity mesaure. If there is no CA activity, the pH level decreases slowly and if there is a high CA activity, the pH decreases quickly.
Validity of screening instruments for the detection of dementia and mild cognitive impairment in hospital inpatients: A systematic review of diagnostic accuracy studies - Study protocol v2
Authors: Benjamin Hwang Aljoscha , Boes Stefan , Nyffeler Thomas , Schuepfer Guido
Published: April 2019

Introduction: As the population ages, Alzheimer's disease and other subtypes of dementia are becoming increasingly prevalent. However, in recent years, diagnosis has often been delayed or not made at all. Thus, improving the rate of diagnosis has become an integral part of national dementia strategies. Although screening for dementia remains controversial, the case is strong for screening for dementia and other forms of cognitive impairment in hospital inpatients. For this reason, the objective of this systematic review was to provide clinicians, who wish to implement screening, an up-to-date choice of cognitive tests with the most extensive evidence base for the use in elective hospital inpatients. Methods: For this systematic review, PubMed, PsycINFO and Cochrane Library were searched by using a multi-concept search strategy. The databases were accessed on April 10, 2019. All cross-sectional studies that utilized brief, multi-domain cognitive tests as index test and a reference standard diagnosis of dementia or mild cognitive impairment as comparator were included. Only studies conducted in the hospital setting, sampling from unselected, elective inpatients older than 65 were considered. Discussion: This is only the study protocol. Results and discussion are pending and will be published after completion of this study.

Este artigo objetiva construir um percurso histórico sobre o ensino profissionalizante e médio no Brasil, bem como, analisar a relação escola/formação/trabalho através das ações governamentais que pautaram a construção da modalidade, no que se refere a implantação e desenvolvimento. Para além desta análise, pretende-se refletir sobre as deliberações tomadas sobre o ensino profissional a partir da aplicação das Leis de Diretrizes e Bases da Educação (LDB) nº 5.692/71 e 9.394/96, nos artigos 39 e 40. Como percurso metodológico para a feitura do texto foram realizadas pesquisas bibliográficas a partir dos estudos exploratórios e analíticos sobre o ensino profissionalizante e médio no Brasil, sobre as LDB de 1971 e de 1996 e as contribuições de livros e artigos científicos que versam sobre o tema. Como maneira de tratar os dados e informações acerca do tema utilizou-se análise e construção de tabelas, mapas e figuras procurando explicar como se deu a configuração da educação profissional no seu percurso, suas imprecisões e ações governamentais. Como resultado o artigo aponta um percurso de estruturação governamental do ensino profissionalizante com o intuito de atender as necessidades econômicas, politicas e sociais vigentes. Todavia, entende-se a necessidade de superação do caráter dualista do ensino médio e profissionalizante para o alcance uma educação baseada em princípios que atendam a pesquisa, o ensino e permita a construção da identidade oposta ao assistencialismo, à formação aligeirada, a fragilidade técnica – científica dos alunos que integram a modalidade.
O CONTEXTO DO CME EM FEIRA DE SANTANA: REVELANDO AS INTERSEÇÕES ENTRE O CENÁRIO NACIONAL E LOCAL

Published: April 2019

A origem dos CME no Brasil tem relação direta com acontecimentos políticos e sociais de caráter mundial, nacional e local, o que exige considerar as relações existentes entre contexto nacional e local. O presente artigo problematizou a criação do Conselho Municipal de Educação, apresentando as relações existentes entre os contextos nacional e local. Para tanto, objetivou 1) contextualizar o surgimento do CME no contexto brasileiro, 2)analisar a criação do Conselho Municipal de Educação de Feira de Santana até o ano de 1996, apresentando as relações políticas estabelecidas no contexto nacional e local. A discussão teórica amparou-se em Ball e Mainardes ( 2011) Castro (2016). Saviani (1988, 2008, 2010), Souza ( 2006, 2013). A opção teórico-metodológica de pesquisa teve inspiração na abordagem do ciclo de políticas.Como estratégias metodológicas foram feitas a análise de documentos oficiais do município de Feira de Santana, a saber Leis Municipais n. 037/90, n.1 477/1991 e n.1 547/1992, Mensagem n. 011/96 do Executivo feirense encaminhada à Câmara de Vereadores, Atas da Câmara de Vereadores do ano de 1989; e a entrevista com um vereador de mandato no ano 1991. Os resultados revelam que o processo de criação do CME em Feira de Santana se iniciou com mobilização popular, encabeçada pelo movimento de professores da educação básica, enfatizando a necessidade de sistematização de espaços coletivos e democráticos na educação municipal, no final dos anos de 1980. Os textos oficiais elaborados no início da criação e organização do CME de Feira de Santana, Lei Municipais n. 037/90 n. 1.477/91 e 1.547/92 revelam tensões, debates, escuta do contraditório e culminam com a construção hibrida que ora revela a tendência de participação e democracia ora a tendência de centralizadora no âmbito da Educação. A descontinuidade administrativa, ocasionada pela forma de gerir e a priorização de outras ações dos novos gestores públicos, além da falta de mobilização docente para a continuidade dos debates acerca do CME e mudança de gestores em Feira de Santana foram aspectos que influenciaram a não continuidade das ações voltadas para a criação e implementação do CME em Feira de Santana até os anos de 1996.

Etnografía del productor araucano de la sabana inundable, Colombia
Authors: Rodríguez-Qüenza Luis Ernesto , Correa-Toro Alonso , Hernández-Rodríguez Milena , Salamanca C. Arcesio
Published: April 2019

El objetivo del presente artículo fue describir la etnografía del llanero habitante de los municipios de Arauca, Cravo Norte y Puerto Rondón, localizados en las sabanas inundables del departamento de Arauca, Colombia, a partir del enfoque sistémico de los diversos agroecosistemas presentes en ellos, de las formas de vida y la relación con la naturaleza, recurriendo a los conceptos de subjetividad e intersubjetividad de la investigación cualitativa, en un “diálogo de saberes” respaldado por entrevistas semiestructuradas con final abierto hechas a 30 productores, diez por municipio. Se seleccionaron 11 temas que ocupan gran parte de la cotidianidad llanera y que posibilitan la existencia de estos productores, para escucharlos de viva voz con la esperanza de construir propuestas concretas surgidas del sentir “llanero anfibio”. Los entrevistados se clasificaron según el tamaño de sus predios y del inventario ganadero así: grandes productores (más de 1.000 bovinos), productores medianos (500 a 1.000 bovinos) y pequeños productores (menos de 500 bovinos). La información obtenida se interpretó desde las perspectivas subjetiva e intersubjetiva y a partir de allí se construyeron los resultados. El 70 % de los entrevistados eran herederos directos de sus predios, muchos de ellos, fundadores, y solo el 30 % del área total era “banqueada” (nivelada), el resto, baja. Predominaba el ganado cebuíno, pero las razas y las sabanas nativas eran también visibles; el 53,3 % de los productores ordeñaban y producían queso artesanal o vendían leche. La economía natural de las explotaciones tradicionales de Arauca y Cravo contrastó con las transformaciones sufridas por los agroecosistemas de los predios de Rondón, más cercanos al dinámico piedemonte. © 2019.

Aspectos reproductivos y pesqueros de Prochilodus magdalenae Steindachner, 1879 (Characiformes: Prochilodontidae) en la ciénaga de Marriaga, río Atrato, Colombia
Authors: Roa-Cubillos Margarita Maria , Villa-Navarro Francisco Antonio
Published: April 2019

Prochilodus magdalenae ha sido históricamente una de las fuentes de alimento de mayor importancia para la población a nivel nacional. Esta especie endémica de Colombia ha proporcionado más del 50 % del volumen de capturas en las principales cuencas trasandinas del país. El aislamiento de la población de P. magdalenae en la cuenca del Atrato hace necesario que se establezcan medidas de conservación ajustadas a sus características biológicas y reproductivas. En el presente estudio se registró información biométrica de las capturas de P. magdalenae provenientes de la pesca artesanal en la ciénaga de Marriaga (cuenca baja del río Atrato) desde abril de 2014 a marzo de 2015. Se registraron 574 individuos de los cuales 427 eran hembras y 147, machos. La distribución de las tallas para las hembras estuvo entre 200 y 470 mm de longitud estándar (LE) y para los machos entre 210 y 415 mm. El análisis de la longitud y el peso evidenció un crecimiento isométrico (b=2,9577) y una gran correlación entre las dos variables (r2=0,8119) para las hembras, en tanto que para los machos el crecimiento fue alométrico negativo (b=1,8793) con una correlación baja (r2=0,5628). La talla media de madurez (TMM) para la población total fue de 365 mm (LE). La época de mayor actividad reproductiva se estimó entre octubre y mayo. La distribución de las tallas y la talla media de madurez (TMM), así como las épocas de desove, difirieron de las registradas en las zonas baja y media del Atrato, así como en las otras cuencas trasandinas. © 2019.

Fabrication of solar cells based on Cu2ZnSnS4 films grown with optimized chemical composition homogeneity
Authors: Gordillo Gerardo , Calderón Clara , Moreno Robinson
Published: April 2019

Se fabricaron celdas solares con estructura Mo/CZTS/ZnS/ZnO usando como capa absorbente películas de Cu2ZnSnS4 (CZTS) crecidas por evaporación simultánea de sus precursores desde una fuente de evaporación coaxial construida con un diseño avanzado que permitió mejorar significativamente la homogeneidad en la composición química en todo el volumen. Mediante mediciones con difracción de rayos X (XRD) se verificó que bajo condiciones de crecimiento optimizado era posible obtener películas en la sola fase Cu2ZnSnS4; los análisis de perfiles de profundidad con espectroscopía de fotoelectrones de rayos X (XPS) permitieron confirmar que las muestras preparadas desde una fuente coaxial crecieron solamente en la fase CZTS y que su composición química presentaba una mejor homogeneidad en todo el volumen que aquellas depositadas desde tres fuentes de evaporación separadas. Asimismo, se encontró que las celdas solares fabricadas con una capa absorbente CZTS crecidas desde una fuente de evaporación coaxial presentaban eficiencias de conversión significativamente mayores que las celdas fabricadas con capas CZTS preparadas desde fuentes de evaporación separadas. Se obtuvieron eficiencias de conversión de 5,6%, una corriente de cortocircuito de 18,3 mA/cm2 y un voltaje de circuito abierto de 0,52 V. © 2019. Acad. Colomb. Cienc. Ex. Fis. Nat.

Published: April 2019

El objetivo de esta investigación fue determinar la diversidad genética de la población de la paloma doméstica Columba livia empleando genes polimórficos asociados con el color del plumaje en San Antero, Colombia. Entre marzo y abril del 2017 se hicieron muestreos aleatorios en cuatro subpoblaciones del municipio de San Antero ubicadas en los sitios de Calle Abajo, Calle Central, Parque Central e Iglesia Central mediante excursiones urbanas, observación directay registros fotográficos, y se clasificaron fenotípicamente 235 palomas. Se estudiaron los marcadores autosómicos Grizzle (G); Spread (S); Checker (C) y Ash-Red (B). Los perfiles genéticos de las subpoblaciones de palomasdomésticas se establecieron con los siguientes índices genético-poblacionales: las frecuencias alélicas, la diversidad genética según Nei (1972), la heterocigocidad esperada (He), el coeficiente de diferenciación genética (Gst), el flujo génico (Nm) y las distancias genéticas entre las poblaciones utilizando el programa PopGene 1.31. Los índices de fijación propuestos por Wright, Fis, Fit y Fst, se calcularon mediante el programa FSTAT v 2.9.3.2. Los marcadores más frecuentes fueron el Checker y el Spread, en tanto que el Ash-Red evidenció las menores frecuencias alélicas. En la población total hubo un alto porcentaje de homocigotos y la diferenciación genética fue baja. Se sugieren posibles efectos de selección en los marcadores Checker y Spread. © 2019. Acad. Colomb.

Determinación de la velocidad de traslación del vórtice anular mediante expansión multipolar
Authors: Gonzalez Jeasson F.
Published: April 2019

Se estableció analíticamente el campo de velocidad inducido por un vórtice anular de relación de aspecto pequeña (r1/r0 donde r0 es el radio de la línea central del vórtice y r1 el radio de su sección transversal), con el objeto de establecer la velocidad de traslación, Γ/4πr0[log(8r0/r1)−1/4], de un vórtice anular con circulación Γ. El campo inducido fue obtenido por la ley de Biot-Savart mediante el método de expansión multipolar, y la traslación fue determinada por la comparación entre los campos obtenidos y la condición material que se satisface sobre la superﬁcie del vórtice. La formulación presentada resulta alternativa respecto a otros métodos ya utilizados para este propósito; sin embargo su ventaja radica en la posibilidad de implementarlo a estructuras vorticales más complejas. La solución encontrada muestra que la velocidad de traslación clásicamente reportada corresponde a una solución de primer orden en el método de expansión multipolar, orden correspondiente a los efectos que la curvatura del vórtice tiene sobre la distribución de vorticidad en su sección transversal. © 2019 Acad.

"A" Loop : A New Loop for Management of Impacted or Ectopically Erupted Canines
Authors: Hazare Ananya , Hazare Deepali , Shenoy Usha , Kamble Ranjit
Published: April 2019

The ectopic eruption and impaction of permanent canine is a common problem encountered in clinical practice. As maxillary canine is the last permanent tooth to erupt (except third molars), it is most prevalent to be malpositioned or remain impacted due to tooth size arch length discrepancy. The orthodontic treatment of impacted maxillary canine remains a challenge to today's clinicians. The treatment of this clinical entity usually involves surgical exposure of the impacted tooth, followed by orthodontic traction to guide and align it into the dental arch so that it comes into occlusion. Auxiliary springs have been used in orthodontics since long for correction of impacted/unerupted canines or adjacent teeth. Cantilever springs are preferred than the continuous wires as placement of continuous flexible wires for correction of these single tooth malocclusions produces an adverse effect on adjacent teeth. A common disadvantage in all of the loops and techniques mentioned above is that it offers a poor anchorage control in extraction cases. Usually the root of impacted canines is near the cortical bone and needs to be brought into cancellous bone, so as to prevent the resorption and also faster movement of the canine. Keeping these points in mind we designed a loop, which fulfills most of the shortcomings, which are discussed above. This loops is called "A loop” as its shape resembles the shape of alphabet "A”. The design, fabrication, biomechanics, advantages and disadvantages of "A loop” are discussed in this article.
Effects of Workplace Ergonomics on Productivity in an Offshore Oil Company
Authors: Liravi Mohammad Ali , Baradaran Vahid
Published: April 2019

Background: The aim of this study is to investigate the relationship between the principles of ergonomics in both material and immaterial dimensions and employee productivity in (IOOC). Methods: Immaterial dimension of ergonomics was measured by variables such as freedom of activity at work and job feedback, and the material dimension of ergonomics was measured by factors such as workplace design and body position. The variables of the productivity construct based on the ACHIEVE model include ability, transparency, assistance, incentive, evaluation, credit, and environment. Each of the constructs was measured by an appropriate questionnaire filled out by 170 operational employees of the Company. Descriptive variables were analyzed using Structural Equation Modeling based on the PLS method to investigate the research hypotheses. Results: The level of employee productivity and ergonomics of the workplace in the IOOC are not desirable due to difficult working conditions and lack of managers' paying attention. The hypothesis of the effectiveness of ergonomics on productivity was confirmed and the material dimension was more effective on employee productivity than the immaterial dimension of human factors. Conclusion: Due to the difficult conditions of the operational units of oil companies, attention should be directed to the physical conditions of the work environment. To improve employee productivity, certain plans for human resource development and management, revision of the designing of the work environment, and work measurement are proposed

ASSESSMENT OF THE NEED FOR VEGETABLES IN ACCORDANCE WITH RATIONAL NORMS OF CONSUMPTION
Authors: Lushchik A. A.
Published: April 2019

Problems of proper nutrition and health of citizens are becoming increasingly important every year. A significant number of chronic non-communicable diseases have been observed in Russia and its regions for several years. Thus, according to the Territorial body of the Federal state statistics service for the Irkutsk region in 2017, the mortality rate from diseases of the circulatory system was 615 people per 100 thousand people, 218 people per 100 thousand people died from neoplasms. The reason for the increase in the incidence of population researchers believe the change in socio-economic structure, lifestyle and diet. At the same time, the President of the Russian Federation defined the task of achieving the average life expectancy of Russians at the level of 78 years in the may Decree of 2018. Currently, for the Irkutsk region, this figure is at the level of only 69 years and at the current rate of growth by 2024 will reach only 75 years. In this regard, we need a set of measures aimed at improving the health, living and working conditions of citizens of the country, which can be implemented, including through ensuring a normal diet of life and consumption of basic products, including vegetables, at a level not lower than the rational norms of their consumption. The article presents an assessment of the capacity and potential of the market of vegetable products on the materials of the Irkutsk region, the main producers, exporters, importers of vegetables, the forecast of shortage of vegetables. Social efficiency in achieving the proposed performance indicators will be determined by increasing the life expectancy of the population, reducing morbidity, improving the quality of life of those suffering from diseases associated with malnutrition, and the ratio of the obtained favorable social results to the costs to achieve them. Economic efficiency will be expressed by assessing the impact of the results achieved in the framework of program activities on the formation of the gross product, ensuring the dynamics of economic growth and increasing productivity, as stated in the presidential decree and Federal national projects until 2024. The practical application of vegetable demand calculations in accordance with rational consumption norms can be used in the process of marketing research to identify the potential market entry of new players or increase the production of fresh vegetables by their existing producers.

The article discusses the issues of import substitution in the market of agricultural products and resources for their production in Russian Federation, ensuring the country's food security. Research results show that since 2014, when the active import substitution policy began, there have been significant changes in the agri-food trade, characterized by a decline in imports and an increase in exports. However, in different product segments of the market the speed of these changes varies. Despite ensuring the country's food independence for most types of agricultural products, the dependence on the import of resources for its production remains significant. At the same time, the demand for agricultural products remains under pressure from declining household income, as well as a significant income differentiation. In this regard, suggestions were made for making adjustments to the doctrine of food security, primarily in terms of assessing the economic affordability of food. Also, an assessment was made of the changes made to the state program for the development of agriculture in conjunction with the strategic objectives of the development of the Russian Federation defined for the period up to 2024. The need to ensure consistency between the tasks assigned to the agro-industrial complex to achieve the country's food security, increasing the export potential of the domestic agri-food products and resources allocated for development, was noted.

The volume and structure of sown areas of vegetable pea varieties of different terms of ripening, selection of the Krymsk Experiment Plant Breeding Station, VIR in the southern region of Russia is shown. When creating new varieties, at present, priority is given to obtaining very early and early, in order to expand the conveyer of raw materials for processing. The merits of the breeding achievements created and included in the State Register are shown: a very early variety Prima (year of inclusion 2016) and an early Kudodesnik 2 (2018), which have already begun to be used in production. However, for processing enterprises in each group of ripening it is necessary to have 2-3 varieties. Therefore, we have set a goal - to create new varieties of vegetable peas of very early and early ripening periods, adaptive to the climatic conditions of the North Caucasus region. The studies were carried out from 2016 to 2018 in breeding fields (Krymsk Experiment Plant Breeding Station, VIR, Krasnodar region). Studied 10 varieties and lines. According to the results of evaluation in competitive variety testing (in 2016-2017), a very early grade of vegetable peas Izyuminka was transferred to the state test. The variety ripens 9 days earlier than the Alpha standard and surpasses it in yield (by 2.2 t / ha.). According to the competitive test held in 2017-2018, in 2019, the early variety Mayak was transferred to the state variety testing, which ripens 4 days earlier than the standard and is almost twice as high in yield. The use of these varieties in the processing industry will significantly increase the period of receipt of grain for processing.

Tarragon (Artemisia dracunculus L.) is a spicy aromatic culture, perspective to use in the food and medical industry. In the collection of aromatic and medicinal plants of the Nikita Botanical Gardens, tarragon is represented by two varieties: Isumrud and Travnevy. The Isumrud variety is characterized by a high content of essential oil (0.6% of the wet weight) of the methylchavicol chemotype (the main component of the essential oil is methylchavicol, whose mass fraction is up to 91%) and is perspective to use not only as a spice, but also in medicine as a reducing facilities. The variety Travnevy contains only 0.1% of the essential oil from the wet mass of the sabineno-elemicin chemotype (the main components of the essential oil are sabinen (40.0%) and trans-from-iso-elemicin – 26.1%), characterized by high productivity of the aerial mass (12 kg/m2), the main direction of use in the food industry as a spice. Due to the lack of requirements for dry raw tarragon, we have developed a draft technical specifications for dry crushed tarragon raw materials TS 01.28.30-009-01579640-2018. Specifications apply to dried whole and crushed raw materials, intended for the manufacture of water and water-alcohol infusions, as a source of biologically active substances, as a component for seasonings to meat, fish dishes, for use in cooking, as well as in the production of alcohol and soft drinks. The main physicochemical indicators of whole and crushed tarragon raw materials (type, size, smell, taste, mass fraction of essential oil, impurities, moisture, ash) are presented.

Often in the soils of crop rotations of grain crops, including on black soil, the content of mobile forms of copper, manganese, zinc and other trace elements is low. Improving the efficiency of making micronutrients for grain crops and determining the best ways and doses of their introduction are topical issues that need to be addressed in order to increase the productivity of crops. The purpose of research is to identify the effectiveness of the use of water soluble compound fertilizer with microelements of the company “Haifa Chemicals” in the technology of growing winter wheat on leached chernozem under conditions of the Oryol Region. Field production experiments were established in 2017-2018 on the basis of Orlovsky Leader LLC Branch №5” located in Livensky district. Field experience with the use of Haifa Chemicals products: Poly-Feed micronutrients 19-19-19 + 1MgO + ME and Poly-Feed 6-15-38 + 3 + ME was laid on soft winter wheat varieties Moskovskaya-56.The control variant was the basic technological scheme used in the household for carrying out leaf dressings with mineral fertilizers together with the organic fertilizer Gumostim. As a result of the research, it has been established that the use of double foliar feeding water soluble compound fertilizer with microelements Poly-Feed 19-19-19 + 1MgO + ME in the tillering stage and at the end of flowering and a single Poly-Feed 6-15-38 + 3 + IU in the subflag phase - flag leaf, increases the height of the plants, as well as the productive characteristics of the ear: the size of the ear, the number of grains in the ear, the mass of grains and their best quality, which in general provides a reliable increase in the yield of grain of winter wheat. At the same time, it was found that, due to leaf feeding, the impact of adverse weather conditions under which the development of winter wheat plants took place in 2018 and their productive properties were laid was leveled out. Due to relatively low additional costs, the use of complex fertilizers of the Poly-Feed brand for winter wheat is economically feasible and can bring additional economic income: based on the maximum level of minimum prices for the grain of the 2018 harvest, it will be 2.07-2.28 thousand rubles / ha regarding base technology. Thus, water-soluble fertilizers, which include Poly-Feed company "Haifa Chemicals" are recommended to domestic agricultural producers for mass introduction in practice of the technology of intensive sheet nutrition of grain and other crops.

Çevresel
radyoaktivite ölçümlerinin temel amacı, insanların doğal kaynaklardan aldıkları
radyasyon dozunun tayini ve insan sağlığı üzerindeki etkilerinin
belirlenmesidir. İnsanlar tarafından alınan ortalama doza en büyük katkı, doğal
radyasyondan gelmektedir (%86). Doğal radyasyon kaynaklarından alınan yıllık
ortalama etkin doz 2.4mSv’dır. Bu dozun büyük bir kısmını dünyanın oluşumundan
beri var olan primordial radyonüklitler (238U, 232Th ve
bozunum ürünleri ve 40K) oluşturmaktadır. İnsanların doğal kaynaklardan
aldıkları radyasyon dozlarının belirlenmesine yönelik çalışmalar son yıllarda
yoğunluk kazanmıştır. Kıyı şeridinin radyoaktivitesi ve doz hızları ile ilgili
dünyanın çeşitli bölgelerinde birçok çalışma yapılmıştır. Fakat Türkiye’de
yeterli sayıda çalışma bulunmamaktadır. Bu çalışmada, Urla ilçesinin kıyı
şeridi boyunca alınan plaj kumu örneklerinin doğal radyonüklit (226Ra,
232Th, 40K) aktivite konsantrasyonları HPGe gama
spektrometre sistemi ile ölçülmüş ve bu bölgede yaşayan insanlar tarafından
maruz kalınan doz hızları hesaplanmıştır. Elde edilen sonuçlar, dünya
ortalamaları ve farklı illerde yapılan çalışmalarla karşılaştırılmıştır.
Sonuçlardan görülmüştür ki, Urla ilçesi kıyı şeridinin gama doz hızları insan
sağlığı açısından bir risk oluşturmamaktadır.
