Authors: Matheus Inciarte María Milagros , Tavares Duarte Fabiola Del Valle
Published: November 2019

La Constitución de la República de Venezuela de 1961, se había convertido desde los años ochenta en un obstáculo para superarla crisis en la cual se encuentra sumergido el país. Centrada en ese propósito, la Asamblea Nacional Constituyente en el año 1999 elaboró varios proyectos de constitución y sancionó la Constitución de la República Bolivariana de Venezuela. La presente investigación, de naturaleza documental, utiliza el método analítico normativo para realizar un estudio comparativo de la Constitución de 1961, Ias Ideas Fundamentales para la Constitución Bolivariana de la V República de 1999, el Anteproyecto de la Comisión Constitucional de 1999 y de la Constitución vigente, en lo referente a la Administración Pública Descentralizada. Si bien la Constitución de 1961 adolecía de fallas, los restantes dispositivos indicados, aun cuando incluyen ciertos cambios, no logran desvirtuar la problemática generada al interior de la rama descentralizada de la Administración Pública. Se propone una evaluación de tal problemática y la promulgación de una normativa general que regule los aspectos esenciales de la Administración Pública Descentralizada.

Authors: Betancourt Belkis , Alarcón Luis , Gómez Irey
Published: November 2019

El objetivo de este trabajo es analizar el fenomeno salud-enfermedad, haciendo enfasis en la presencia de la leishmaniasis y la percepcion que tienen los pacientes y no pacientes con respecto a esta enfermedad y al servicio que prestan los organismos de salud, en la atencion, prevencion y control de la misma. El referente empirico lo constituyen los habitantes de las comunidades de San Pedrito, San Pedro y Vega Grande, ubicadas en el municipio Sucre, del estado Sucre, las cuales hacen uso del Servicio de Dermatologia Sanitaria (SDS), en la ciudad de Cumana. Se utilizo la entrevista estructurada y la observacion participante. Entre los resultados cabe destacar que el estilo de vida de los pacientes y el desconocimiento acerca de la leishmaniasis inciden en su prevalencia y emergencia. De igual modo, la percepcion y los prejuicios de los pacientes inhibe el uso de los centros de salud y la puesta en practica de medidas preventivas. El rol del SDS es principalmente curativo, siendo los pacientes y la comunidad en general, sujetos pasivos en el proceso de tratamiento y control de la enfermedad. Se concluye que para mejorar la gestion es conveniente descentralizar el SDS y considerar las caracteristicas socioeconomicas y socioculturales de los usuarios.

Abstract. The work purpose – to get information about the modern state of natural lands (rural pastures) which a cattle and sheep of individual sector are based on and to offer measures on renewal and maintainance of natural vegetation. Technique and objects of a research. The statistical analysis in dynamics of number of cattle and sheep, including on categories of farms is made. The geobotanical description of the vegetation is carried out on registration platforms of 100 m² to the O. Drude’s system. Determination of biological productivity of a vegetable cover was carried out by a hay crop in the same place (from 0.5 m² in sixfold frequency). The objects of our research are the village pastures. Results and practical importance. The analysis of a livestock of animals on categories of farms of Stavropol region is shown. For the last 18 years population in an individual sector, including peasant (farmer) farms and farms of the population increased by 1.6 times. Within the studied communities vegetation modifications with the dominating plant species are revealed: Achillea setacea, Artemisia austriaca, Poa bulbosa, etc. They are spatially unhomogeneous, on specific composition poor. The quantity of types on the registration square (100 m²) averages 24, with fluctuations from 17 to 28. An assessment of fodder potential of natural grass stand degradaded, extents of their degradation is given. Grass stand degradaded, has poor quality of a forage. In its structure up to 74 % of the not virgin land species which do not have feeding value: Artemisia austriaca, Convolvulus arvense, Erodium cicutarium, etc. Scientific novelty. Negative consequences of unsystematic pasturage of the cattle on the limited area of the rural pastures which are under authority of municipal units are shown. Restoration of the degradaded areas of rural pastures by method of agrosteppes is recommended. In its basis – use of seeds of wild-growing steppe herbs.

Abstract. A scientific novelty is the study of the allele pool of domestic reproduction pigs, the determination of population genetic parameters by DNA markers, and the search for associations of genetic variants with economically significant traits. The aim of the work was to study the influence of SCD Y487830 polymorphism: g.2228 T > C to the IMF content and to search for associations of genotypes with economically significant traits in domestic reproduction pigs. The studies were conducted in 2019 on pigs reared in Selection and Hybrid Center LLC (Voronezh region). Genotyping were determined by the QuantStudio™ 5 Real-Time PCR System using the developed test system. The content of IMF (%), backfat thickness (mm), lean (%), live weight (kg) in 103 boars and 27 gilts Duroc pigs, 30 Large White boars was determined using an ExaGo ultrasound scanner. The main diet and animal welfare conditions were identical and corresponded to zoosanitary standards. Model equation for multivariate analysis of variance with interaction was used to evaluate the effect of genotype by SCD on productive qualities. The frequency of the T allele and TT genotype in the group of Duroc pigs was 0.419 and 12.7 %, respectively. Large White pig breeds were characterized by the frequency of the T allele – 0.686, TT genotype – 46.8 %. All Landrace pigs were carriers of the TT genotype. The superiority of the C allele carriers in the content of IMF was shown. The difference between Duroc boars with TT and CC genotypes was 0.42 % (P ≤ 0.05), and individuals with CC genotype exceeded TT genotype carriers in the backfat thickness of more than 3 mm (P ≤ 0.001). The results confirm the association of the SCD genotype with the content of intramuscular fat and the backfat thickness in the Duroc boars.

Authors: Sup Devid Frastiawan Amir
Published: November 2019

Cessie is the submission of accounts receivable in the name regulated in Article 613 of the Civil Code. Cessie in principle is the sale and purchase of receivables, but in its development the cessie can also be used as collateral for debt. In Islamic law, detailed discussion of cessie has not yet existed, but in general the issue of accounts payable has been discussed in the hawalah contract. In the DSN-MUI fatwas cessies are categorized as active subjective innovations or forms of subrogation accompanied by compensation. On the other hand, conceptually, cessie, subrogation and innovation are different. From this description, this research will discuss about cessie in Islamic law review with hawalah approach. The research method used is qualitative-descriptive-literature. The conclusion obtained from this study. (1) Cessie requirements according to the Civil Code have not fulfilled the entire requirements for the formation of the contract contained in hawalah. (2) Cessie in the sale and purchase of receivables is included in hawalah haqq. (3) Cessie as debt collateral is included in hawalah haqq based on kafalah (guarantee). In the case of retro cessie, Hanafi scholars allow while Shafi'i scholars do not allow

Published: November 2019

This journal explains about the Habib Seunagan followers’ calculation method of the beginning of Ramadan’s determination and normative review of the practice of determining the beginning of Ramadan which has been used to date. The result of the research can be explained that Habib Seunagan’s followers use hisab ‘urfi khumasi (not hisab hakiki taqribi) that has been modified from the original method by adding abstinence day before the beginning of Ramadan fasting on Wednesday and Friday to begin Ramadan fasting. Normatively, after considering the legal basis from Alquran, Hadist, and fatwa ulama about the beginning of Ramadan’s determination, then the Habib Seunagan followers’ practice of determining the beginning of Ramadan based on hisab ‘urfi khumasi is not in accordance with the provisions of the law, considering that when starting Ramadan fasting, the essence is still on the 28th or the 29th of Sya’ban based on hisab hakiki tarqibi and can be proven by the sight of the old crescent in the eastern horizon before sunrise on the first day of the Habib Seunagan followers’ Ramadan fasting.

中西方艺术文化差异对室内设计的影响及发展解析
Authors: 刘 永炎
Published: November 2019

二十一世纪的今天,室内设计领域可以说得到了高速的发展,过去“传统”的思想理念逐渐开始变得模糊化,室内空间设计开始向“共性化”的方向发展。中国室内设计与西方室内设计对比分析,中国的室内设计大体上在创意方式与创意风格方面存在一定的差异性,而西方室内设计创意大多是在各国家传统文化艺术的基本前提下发展而成的,其发展历程各有特征,但是在一定程度上都保有了本地的文化特色,最终是为了给子孙后代留下历史文化的痕迹,在这一发展变化过程当中不排除西方文化对国土文化的影响,可是并不会给本民族文化面貌和个性特征,现代化室内空间设计最终所追求的是各民族共存,从而形成全新的发展风格。接下来,本篇文章围绕中西方艺术文化差异对室内设计的影响及发展进行论述,望能够对大家有一定的参考借鉴价值。

Published: November 2019

The efficiency of prepared nano-abamectin was assayed against two-spotted spider mite, Tetranychus urticae (Koch). Prepared formulation showed spherical particles ranged from 66 to 133 nm under examination of Transmission Electron Microscope (TEM) and same pattern of Fourier Transform Infrared (FTIR) spectrum in comparison of conventional acaricide (Vertimecâ). In laboratory trail, toxicity index at LC50 level confirmed that nano-abamectin was greater toxic to adult female, T. urticae (Koch) with value; 30 than Vertimecâ 1.8% EC. Similarly, nano-abamectin reduced the mite fecundity at levels greater than those of Vertimecâ. Regarding field trail, nano-abamectin at rate of 60 ml/ha showed very toxic effects after 3 day of spraying followed by 7 and 14 days on soybean plants achieving % of mortality; 89.98, 83.80 and 76.90%, respectively. These findings showed that, bioactivity of nano-acaricide were many folds higher than conventional acaricide against mite, T. urticae (Koch). However, the biosafety issues may be also addressed.

There is paucity of studies relating to fish corral fishery and its management particularly those operated on reef flats. This study was conducted to evaluate the fish catch composition of fish corrals situated in the reef flat of Palompon, Leyte from July 2009 to January 2010. During the monitoring, two sets of data were utilized: the semimonthly field intercept samplings and the daily fish landing data. Field intercept samplings enabled the researchers to approach fishers as they were gathering their fish catch that was eventually identified, sorted, measured, and weighed. Fish landing data recorded by local enumerators included the fish’s local name and corresponding weight. From 27 fish corrals, the intercept samplings yielded a total catch of 23.9 kg, which was composed of 81 identified species under 47 genera from 31 families. The most abundant family was Siganidae comprising 44% of the total catch, followed by Apogonidae (18%) and Pomacentridae (9%). This composition was corroborated by the fish landed data. The temporal and spatial trends of the catch composition showed that Fam. Siganidae was most abundant in the months of July, October, and December, while Apogonidae in the months of August and November. It was observed that there was an unequal spatial distribution of fish species in the study area. Of the four sampling areas, Area 2 on the northeastern part of Palompon was the most diverse due partly to the high number of fish corral units and the area’s structural complexity wherein seagrass and algal beds were most extensive interspersed with coral patches. Results of this study could serve as reference for future studies dealing with monitoring and managing fish corral fishery.

Published: November 2019

We developed a cost-effective bleaching method for overcoming the brightness ceiling of thermomechanical pulp (TMP) made from mill chips containing predominantly mountain pine beetle-infested lodgepole pine. The method involves synergistic bleaching of the TMP in the refiner with hydrosulfite (Y) and diethylenetriaminepentaacetic acid (DTPA) as the chelating agent. The synergistic, in-refiner Y+DTPA bleaching, when followed by post-refiner Y or peroxide bleaching, can provide higher brightness gain or lower bleaching chemical cost for Y- or peroxide-bleached TMP from the mill chips. Estimated cost savings for Y bleaching to 60.0% ISO brightness and peroxide bleaching to 74.3% ISO brightness are USD 5.2/ton pulp and USD 5.2-6.2/ton pulp, respectively.
Evaporation of Na2CO3-Na2SO4 solutions: A method to evaluate the distribution between bulk and surface crystallization

Published: November 2019

Precipitation of sodium salts in black liquor evaporators causes problems by forming scales on the evaporator surface, reducing heat transfer and cleaning intervals. Most problems are connected with the crystallization of sodium carbonate and sodium sulfate. As the solubility of these salts is exceeded, a crystal mass must form somewhere. Crystallization can occur either in the bulk solution, on the heat transfer surface, or on other surfaces. It is always desirable to create bulk crystals. If crystals form and remain on the surfaces, a layer of scales will build up with time.
A method for estimating the distribution of crystal masses between the bulk and on surfaces has been developed in this work. The method is primarily based on inline density measurements combined with inline measurements of the system’s water mass. It has been applied to aqueous solution of sodium carbonate and sodium sulfate in a research black liquor falling film evaporator. Experiments have proven that the method gives valuable information on the crystallization process. It shows where crystals are formed during primary nucleation, as well as during the subsequent continuous crystallization.
In an industrial black liquor evaporator, the metastable limit can be passed if it is operated under non-steady-state conditions. During evaporation, upon passing the metastable limit, the experiments showed that the surface crystallization is as high as or higher than the bulk crystallization. During the subsequent crystallization process, when concentration is further increased, the crystallization rate is higher in the bulk solution than on the surfaces.

We conducted a comprehensive review of air emissions resulting from burning wood residues in industrial boilers and potential methods to control these emissions. This report compares average emissions with similar data published by the U.S. Environmental Protection Agency for the burning of fossil fuels coal, oil, and natural gas in industrial boilers. As compared with coal or oil combustion, wood combustion in boilers generally leads to lower emissions of trace metals, hydrochloric acid, sulfur dioxide (SO2), and nitrogen oxides (NOx); higher emissions of carbon monoxide, polyaromatic hydrocarbons, and total volatile organic compounds; and comparable emissions of particulate matter and polychlorinated dibenzo-dioxins and -furans (PCDDs/Fs) (both of which are highly dependent on the efficiency of the ultimate particulate matter control device). Most importantly, wood combustion is carbon dioxide-neutral, a distinct advantage over fossil fuel combustion. Firing wood in stoker units with sulfur-containing fuels, such as coal and oil, leads to a reduction in expected SO2 emissions because of the high carbon and alkali content of most wood ash, and cofiring wood with coal also has some benefits for NOx reduction. This report also discusses the generation and types of combustion ashes resulting from wood burning in mostly combination boilers in the United States and Canada, and provides an overview of ash management practices and the salient characteristics of such ashes relative to their trace metal, organic, and PCDD/F contents.

Published: November 2019

A mill in Eastern Canada experienced significant sticky deposit formation on one of the guide rolls of the supercalendering stack in its supercalendered paper production line. To investigate, and minimize, the formation of those sticky deposits, we collected deposit samples from a supercalender stack and analyzed them for their chemical compositions, metal ion contents, and thermal properties. Acetone soluble substances, which were considered as pitch or wood extractives, were shown to account for the majority of these deposit samples. The thermogravimetric analyzer gave the result that, for the deposit sample, the mass loss due to heating in the temperature range of 50ºC–200ºC was less than 5%. Gas chromatography results showed similar chemistry for the deposit samples both before and after the thermogravimetric analyzer analysis. Throughout the mill process, a large portion of wood extractives passed through the thermomechanical pulp mill and into the paper mill with the pulp streams. Two control programs, detackification versus fixation, were compared to evaluate their ability to decrease the extractives-related deposit formation on the supercalendering stack.
A Colour Perception Detection Model Based on The Spectral Characterictics
Authors: Mina Irwan Anto
Published: November 2019

Information needs for one's color perception are needed in the fields of medicine, engineering, astronomy, biomedicine and so on. The demand for accurate assessment of color perception must be met by the perception detection tool used. Ishihara's test, as a perception detection tool that is still used today has insufficient accuracy. This research aims to create a system that can detect a shift in one's color perception, relative to the average color perception of a number of respondents. Through plotting the respondents' perception points, in the CIE coordinate system (Commission International de I'Eclairage) XYZ can be calculated the average euclidean distance, ED, relative to the reference point and the distribution of x and y groups of perception points around the point of reference. Both size, euclidean distance and distribution are used as indicators of average color perception so that an assessment of one's color perception is given based on the results of comparison between color perception points and color perception indicators. The tool used to do the test is Delphi version 7.0 software. the research material used is the RGB (Red, Green, Blue) color image format. The results of a person's color perception study are divided into three levels, namely: (1) "normal" assessment if euclidean (ED) perceptions are smaller than the euclidean (ED) average (2) the "somewhat normal" assessment if the distribution of x and y is smaller rather than the color of perception and the distribution of x and y (3) the assessment is "abnormal" if the color of perception is greater than the max distribution of x and y. A new perception point assessment that is in level one is used to up-date prevailing perception indicators. Up-dating condition constraints affect the quality of the threshold average perception specifically and the quality of the results of the perception detection system in general.

Ebola viral disease (EVD) is a deadly infectious hemorrhagic viral fever caused by the Ebola virus with a high mortality rate. Until date, there is no effective drug or vaccination available to combat this condition. This study focuses on designing an effective antiviral drug for Ebola viral disease targeting viral protein 30 (VP30) of Ebola virus, highly required for transcription initiation. The lead molecules were screened for Lipinski rule of five, ADMET study following which molecular docking and bioactivity prediction was carried out. The compounds with the least binding energy were analyzed using interaction software. The results revealed that 6-Hydroxyluteolin and (-)-Arctigenin represent active lead compounds that inhibit the activity of VP30 protein and exhibits efficient pharmacokinetics. Both these compounds are plant-derived flavonoids and possess no known adverse effects on human health. In addition, they bind strongly to the predicted binding site centered on Lys180, suggesting that these two lead molecules can be imperative in designing a potential drug for EVD.

Published: November 2019

The results of comparative design research in the thermal stress and strain state of the piston in transport diesel engine 2 F 10.5/12 are given for its rated power operation. The standard piston is made of an aluminium alloy, and the modernized one, of steel. Piston thermal profiling and indicator test results were used for identifying the mathematical models and refining the boundary conditions for mechanics and heat conduction problems. To ensure reliable heat rejection from the piston, the paper considered the case of oil jet cooling. This was taken into account when describing the boundary conditions of the heat conduction problem. The thin-wall steel piston with oil jet cooling was shown to function reliably under the study conditions. The temperature in the first compression ring groove does not exceed 200 °С, and the radial deformation of the piston crown is less than half of that of an aluminium alloy standard piston.
