Authors: Afdhol Muhammad Khairul , Lubis Hafni Zulaika , Siregar Chalidah Pratiwi
Published: April 2019

Global demand for energy needs has increased due to the rapid development of the human population, raising the industrial prosperity in developing countries. Primary energy demand is still supplied from fossil fuels, such as oil, coal and natural gas. The utilization of fossil fuels will continuously enhance the effect of greenhouse gases in the atmosphere. On the other hand, the extent of the tea plantation area in Indonesia reached 53,009 Ha, so that it will reproduce a waste too. Thus, spent tea as bioetanol. In addition it contains cellulose fibres are quite high, environmentally friendly and economical. Bioethanol as motor vehicle fuels can reduce the addition of CO2 at atmosphere because the use of biomass for the production and usage of bioethanol can be considered as a closed cycle. According to this principle the buyer of CO2 from fuel combustion bioethanol originating from the CO2-based biomass will be reabsorbed by plants through photosynthesis reactions. As a result of this whole process is not accounted for emissions of CO2 liquid gas a greenhouse gas into the atmosphere. Bioethanol-cellulosa can reduce greenhouse gas emissions amounted to 80%. The process into products bioethanol via hydrolysis, fermentation, distillation and characterization using Gas Chromatography-Mass Spectrometry (GC-MS). Them is the optimal bioethanol levels produced from fermented inoculant 1% amounting to 8.2% and optimal levels of bioethanol produced from hydrolysis of 8% H2SO4 results amounted to 8.2%, thus optimumsitas the ethanol produced from 8% acid and 1% inoculant apply to have levels of ethanol amounted to 8.2%. The product program could be developed into bioethanol solvent to dissolve the oil that is waxy crude oil.
Thermodynamic Stability of Hexagonal and Rhombohedral Bn at Cvd Conditions from Van der Waals Corrected First Principles Calculations
Authors: Pedersen Henrik , Alling Björn , Högberg Hans , Ektarawong Annop
Published: April 2019

Thin films of boron nitride (BN), particularly the sp2-hybridized polytypes hexagonal BN (h-BN) and rhombohedral BN (r-BN) are interesting for several electronic applications given band gaps in the UV. They are typically deposited close to thermal equilibrium by chemical vapor deposition (CVD) at temperatures and pressures in the regions 1400-1800 K and 1000-10000 Pa, respectively. In this letter, we use van der Waals corrected density functional theory and thermodynamic stability calculations to determine the stability of r-BN and compare it to that of h-BN as well as to cubic BN and wurtzitic BN. We find that r-BN is the stable sp2-hybridized phase at CVD conditions, while h-BN is metastable. Thus, our calculations suggest that thin films of h-BN must be deposited far from thermal equilibrium.
MODEL OF A MATRIX CROSSCORRELATION FUNCTION OF THE PROBING AND REFLECTED VECTOR SIGNALS FOR A CONCEPTUAL DESIGN OF A SYNTHETIC APERTURE RADAR ON AN AERIAL CARRIER

Published: April 2019

In order to simulate the process of design development in full on computer models, including virtual tests of the synthetic aperture radar on an air carrier in model media, the study develops a structural scheme of the conceptual design of the synthetic aperture radar on an air carrier. The scheme is invariant with respect to the type of an air carrier with a synthetic aperture radar: an aircraft, a helicopter, an unmanned aerial vehicle and similar ones: an air carrier "enters" it by only an automatic control system, a model of trajectory instabilities and a spectrum of frequencies of elastic oscillations of its design. To perform a computer simulation of radar systems with full polarization sensing, a model of a matrix cross-correlation function of probing and reflected vector signals is proposed. As a model of the scattering object, a set of independent point reflectors distributed over space and generally having different rates of motion is accepted. The reflected signal is a sum of elementary signals, their form completely repeats the shape of the emitted signal, and the amplitude, the phase and polarization are respectively determined by the coordinate, velocity and polarization parameters of elementary reflectors forming a spatially extended object. Taking into account the developed models for the formation of the vector sounding signal and the matrix response function of the distributed radar object, a block-diagram of the model of the matrix cross-correlation function of the emitted and reflected vector signals is proposed. A block-diagram is the basis for the development of an algorithm and a program for computer modeling of the primary signal processing in a radar station with full polarization sensing.

Uma breve história da automação de bibliotecas universitárias no Brasil e algumas perspectivas futuras
Authors: Viana Michelângelo Mazzardo Marques
Published: April 2019

A automação das bibliotecas universitárias no Brasil passou por uma reserva de mercado de computadores e de softwares, que ocorreu no país entre 1980 e 1990, a qual restringiu a adoção inicial de sistemas de automação. No entanto, foi muitas vezes desenvolvida de formas criativas: sistemas e aplicativos foram criados e usados em diversas universidades, alguns como software livre, outros baseados na plataforma ISIS da UNESCO, além da adoção de modernos sistemas estrangeiros, que aconteceu apenas nos anos 1990. A primeira parte do artigo resume a história do desenvolvimento da automação de bibliotecas universitárias do país, desde o momento em que os pesquisadores brasileiros começam a disseminar a informática, criando a cultura da automação em instituições de ensino superior. Muitas pessoas e instituições também contribuíram para promover e implantar a automação em bibliotecas universitárias. A segunda parte do artigo trata de perspectivas futuras em automação de bibliotecas acadêmicas no Brasil com ferramentas de descoberta, sistemas de próxima geração baseados em nuvem e equipamentos de automação de bibliotecas. Apresenta também alguns desenvolvimentos futuros possíveis.
O papel dos arquivos das instituições federais de ensino superior e a experiência do Arquivo Central da Universidade de Brasília
Authors: Roncaglio Cynthia
Published: April 2019

As Instituições Federais de Ensino Superior no Brasil, assim como outras instituições da administração pública, são detentoras de arquivos formados em decorrência das suas atividades – no caso das IFES, atividades administrativas e acadêmicas decorrentes das suas funções finalísticas: ensino, pesquisa e extensão. Ao longo da sua existência as IFES adotaram procedimentos diversos de organização e tratamento dos documentos arquivísticos, não necessariamente baseados em conhecimentos técnico-científicos da Arquivologia. Isto, em parte, porque a legislação arquivística, que estabelece uma série de normativas sobre o assunto, teve início apenas nos anos 1990. Recentemente, percebe-se a influência crescente da Arquivologia na (re)estruturação dos arquivos das IFES e o estabelecimento de normativas federais próprias para os arquivos de universidades. Tal fenômeno tem a ver, em certa medida, com o Programa de Apoio ao Plano de Reestruturação e Expansão das Universidades (REUNI), – com a consequente expansão dos cursos de Arquivologia no país e contratação de arquivistas para atuar nas instituições universitárias e também com a Lei de Acesso à Informação de 2011. Este artigo visa a descrever algumas dessas transformações e apresentar a experiência do Arquivo Central (ACE) da Universidade de Brasília (UnB) referente às estratégias de visibilidade e sensibilização da comunidade universitária para a importância dos arquivos para a administração, ensino, pesquisa e extensão.

Published: April 2019

Life Force LLC, RPE products were studied on irrigated dark chestnut soils of the Saratov Transvolga region.  The objects of the studies were Chantenay carrot variety and products, containing humic acids, as well as macro (nitrogen), meso (calcium, magnesium and trace elements).  The purpose of the research is to determine the most effective combinations of humic acid salts and chelated micronutrient fertilizers that provide a substantial increase in the yield of carrots. It is established that spraying carrots with a solution of Reasil® micro Hydro Mix increased the harvest of standard root crops by 1.85 т/ha for an average of three years (by 7% to the control). When using K- Humate -Na with micronutrients the yield increased by 5.51 t/ha (by 20% to the control). The maximum productivity of carrot within our experiments was obtained with the double application of Reasil®  Carb-N-Humic along with K-Humate -Na with micronutrients (35.88 t / ha). Similar results (35.69 t / ha) were obtained when Reasil Ca-Mg-B Animo was used along with K- Humate -Na with micronutrients. The growth of carrots and the formation of the crop were significantly influenced by the weather conditions of vegetation season. The studied products had a positive effect on the output of standard root crops, the content of sugars, vitamin A and nutrients. The content of nitrate nitrogen in all variants of the experiments was almost the same and about 4 times lower than the maximal permissible concentration (MPC). The removal of macronutrients from the soil with the carrot yield increased under the influence of microelement fertilizers.

In the southeastern agro-climatic zone of the Nizhny Novgorod region, 51 parasitic systems function retrospectively, the co-agents of which, apart from their pathogens, were productive and unproductive domestic and wild animals. For the entire depth of retrospection (82 years), eleven nosoforms of infectious pathology in the studied region (27.6%) were dominant in the number of enzootic foci and diseased animals (rabies, dictiocaulosis, infectious atrophic rhinitis, classical swine fever, pyroplasmosis, salmonellosis, swine mucus, anthrax, fasciolosis, emkar, foot and mouth disease). Their share in the nosological profile of infectious pathology accounts for 261 epizootic focus (74.1% of the total epizootic focus of infectious animal diseases in the region for the entire depth of retrospection). At the same time, 13 nosoforms in the study area for the entire period of retrospection were recorded once, the expansion of the boundaries of their epizootic process was not established, the removal of the causative agent of these infectious diseases beyond the limits of the primary epizootic focus was pre-empted. Not allowed and relapses of their epizootic phenomena in the region. Ten nosoforms of infectious pathology of animals (18%) in the total pathology of animals in the studied region were recorded twice for the entire period of retrospection (typhoid fever, pig taineosis and cattle, pig metastrongylosis, infectious cattle, chicken ascaridiosis, cattle parainfluenza, nosomatosis bees). In the southeastern zone of the Nizhny Novgorod region, the potential danger of spontaneous emergence and spread of infectious animal pathology (anthrax, emkar, tuberculosis of cattle, fascioliasis, classical and African swine fever, pyroplasmosis, echinococcosis, rabies) has been identified. Schemes-models of the potential threat to the epizootic component of the biological hazard in the region were constructed.

Authors: Moayedi Mohammad , Kheyroddin Reza , Shieh Ismail
Published: April 2019

Studying the status of urban social capital indicates that it is declining in contemporary cities. The experts in the field of social science have seriously warned on the consequences of this decline, by examining the components of social capital which is the result of forming norms of collective life and social interaction. In this regard, urbanization knowledge seeks to strengthen social capital through targeted interventions and efforts to improve the quality of urban life. Social interactions are significantly important factors contributing to the social capital and one of the most effective ways of realizing social interactions is making and developing of "public urban places". Regarding the previous studies which show that public places are created for people's presence and social mobility, this study seeks the ways for strengthening social capital by interventions in public places and increasing their quality by determining the role of urban spaces in improving the status of social capital. For a better study of the subject, using a desk research method, field observation and scrolling through a questionnaire, the market pedestrian located in the central area of Tehran was studied. The collected data were analyzed by SPSS software and the results showed that interventions with the aim of pedestrianizing and attempts to make a high quality place increase presence of people and cause a high tendency to establish social interactions.in fact pedestrian-orientation of urban areas has facilitated face-to-face and collective communication by influencing the social trust and solidarity, also it has helped with strengthening the tendency to participate and cooperate. Hence, adoption of the pedestrian-orientation policy and efforts to improve the quality of public places, have enhanced the social capital of city.

Published: April 2019

This paper investigates the compressive strength properties of concrete with Ground Granulated Blast Furnace Slag (GGBS) and Fly Ash in concrete by partial replacement of cement. The incremental demand of cement in the construction field is a concern for environmental degradation, in this regard; replacement of cement is carried out with waste materials by using GGBS and Fly Ash. On optimum level of GGBS and Fly Ash was assessed with varied percentage from 0 to 30% for different curing days. Replaced concrete were tested with the slump, compaction factor, Vee-bee and compressive strength. Cement to water ratio was maintained at 0.47 for all mixes. The compressive strength tests were conducted for 3, 7, 14 and 28 days of curing on a M25 grade concrete. The results obtained from the slump, compaction factor, Vee-bee and compressive strength of concrete containing GGBS and Fly Ash was increased as the curing time increases. The workability of replaced concrete improved when slump value achieved 30% as compared to controlled one SF0 and the compressive strength obtained 26.30% improvement at SF9 as compared to SF0. The outcomes indicated that the addition of GGBS and Fly Ash enhances the workability and compressive strength which eventually improved the mechanical properties of concrete.
Characteristics of Traffic Accidents in Baghdad
Authors: Albayati Amjad H. , Lateef Ishraq Mahdi
Published: April 2019

Road traffic accidents (RTAs) are events that suddenly, inadvertently and unexpectedly occur under unforeseen circumstances that involve at least one moving vehicle and result in one or more road users being killed or injured. Unfortunately, Iraqi governorates suffer from higher rates of traffic accident casualties compared with the rates of casualties from terrorist attacks; this situation reveals a serious and growing problem. Road traffic accidents are not easy to eradicate. However, their prevalence can be reduced to the barest minimum via periodic assessments of traffic accident characteristics and the most important aspects for road authorities to consider when designing and evaluating the performance of a road to improve traffic and road users’ safety.Therefore, the primary objective of this paper is to evaluate traffic accidents in Baghdad using a retrospective analysis of accidents that occurred from 2006–2016 taking into consideration the following parameters: the cause of the accident, the genders of the victims, the number and type of vehicles involved in the accident, the time of the accident, the severity of the accident, the type of accident and the age group of the driver(s). The data were been obtained from the Central Statistical Organization in the Ministry of Planning. The results reveal that 12,019 RTAs occurred in the city of Baghdad; on average, 1,092 RTAs occurred each year. Twenty-two percent of the RTAs resulted in death, 67% resulted in injury and 6% resulted in both deaths and injuries. Only 4% of the RTAs resulted in property damage without victims. To this end, Baghdad has the highest prevalence of RTAs of all Iraqi governorates. These results provide scientific evidence to mobilize road authorities to effectively and urgently develop adequate traffic strategies and policies to reduce the epidemic of RTAs in Baghdad as well as other Iraqi governorates.
Sign language learning and assessment in German Switzerland: Exploring the potential of vocabulary size tests for Swiss German Sign Language
Authors: Haug Tobias , Ebling Sarah , Boyes Braem Penny , Tissi Katja , Sidler-Miserez Sandra
Published: April 2019

In German Switzerland the learning and assessment of Swiss German Sign Language (Deutschschweizerische GebÃ¤rdensprache, DSGS) takes place in different contexts, for example, in tertiary education or in continuous education courses. By way of the still ongoing implementation of the Common European Framework of Reference for DSGS, different tests and assessment procedures are currently been developed and their potential are explored to support the learning and assessment of DSGS. Examples of this are two vocabulary size tests. The first is a web-delivered Yes/No Test, the second a Translation Test from written German to DSGS. For both tests, the same set of items was used. The items were sampled from DSGS teaching materials.
For the development of the two vocabulary size tests, 20 DSGS adult learners of ages 24 to 55 (M = 39.3) were recruited as test takers. An item analysis of the test results yielded candidates for removal from the item set. Cronbach’s Alpha showed good results for both tests (>.90), and inter-rater reliability of the translation test also indicated promising results (Cohen’s Kappa = .613, p <.001). Evidence contributing to content validity was collected based on the sampling method of the test items. Due to the lack of a second DSGS vocabulary test that could be used to establish concurrent validity, external variables were identified and investigated as possible external criteria contributing to the performance of the test takers. One variable, number of courses attended, showed a significant correlation with the test results.

Published: April 2019

Adder compressor architectures have been widely used in multipliers and have recently achieved improvements over conventional approaches in the computation of multiple modules, such as transform blocks, in the context of video coding. This paper reviews four different state-of-the-art 8-2 adder compressor architectures and proposes a novel one. A 65 nm commercial standard cell library was used to synthesize the compressors. The results show that, as a consequence of a shorter critical path, our circuit presented significant improvements regarding maximum operational frequency, while still maintaining similar results for power dissipation. Our circuit also managed to achieve a smaller circuit area, as a result of a more straightforward net interconnection.

Marine area surrounding the islands in Gili Matra Marine Park provides a space for marine transportation, fishing and tourism activities. An increase in number of visitors implies more intensive use of the marine areas that can promote potential conflicts among the users. This study provides an analysis to asses the carrying capacity of several zones dedicated for marine transportation, i.e. ports and their adjacent waters, in 2019 and 2013. The ports support local people and visitors mobility around the islands and connection between the islands and the mainlands, such as Lombok and Bali islands. Field activities was carried out to directly observe Gili Indah village from September 2013 to January 2015, including collection of data on local population and visitors. This study applied a geographical analysis on satellite historical images published by Google Earth (August 2009 and September 2013) to obtain data on the number, distribution and size of transportation vessels, and usage of the zones. Significant increase in number of visitors was observed while local population has been leveling off since 2012. The port zones were intensively utilized during the observed peak season; the boat density reached 3, 1, 2 boats per 10 meters shorelines in Gili Air, Meno and Trawangan, respectively. It is recommended that each boat should be provided at least 5 meters of shoreline. Hence, the maximum number of boats that can be accommodated at one time in the port zones at Gili Air, Meno (3 ports) and Trawangan (2 ports) are 48, 25 and 38 units, respectively.Limit on accommodation facilities and number of boats in each zone can be used to control potential conflict in among marine users and threats to coral reefs or other marine attractions andsafety of visitors.

On the one hand, Indonesia rejects corruption, but on the other hand, it commits actions that support corruption. Meanwhile, Japan has a strong culture of shame for committing law violations both at the community level and law enforcement officers.

The Usage of Chitosan from Shrimp Waste as Natural Preservative for Fish Cilok (Traditional Food in Indonesia)
Authors: Jayawardana H.B.A , Afandi Ahmad
Published: April 2019

Cilok is one of the traditional food in Indonesia. Cilok is a popular treat among Indonesians due to its good taste and cheap price. To make it last longer, cilok is sometimes added with preservative. However, such attempt will endanger consumers if dangerous preservatives are used, such as formaldehyde and borax. Their usage in food preservation may negatively impact consumers’ health. The aim of this research was to develop an alternative, natural preservative for fish cilok. The preservative would be chitosan. The method used is an experiment that is by making a chitosan solution from the shrimp skin waste. In the experiment, chitosan was extracted from shrimp waste. A 1,5% chitosan concentrate was used. Its preservation potency was tested by giving three treatments towards fish cilok: fish cilok with 1,5% chitosan coating; fish cilok mixed with 1,5% chitosan solution and fish cilok without chitosan. The three treatments were observed and an organoleptic test was performed according to the preservation time in a room temperature on Day 1, 2, 3, 4 and 5. The parameters tested during the experiment were taste, color, odor and texture of fish cilok. The research results showed that fish cilok coated with 1,5% chitosan solution lasted longer than fish cilok without or added with chitosan.

El Museo de Quai Branly-Jean Chirac. El discurso normativo de la museología
Authors: Galindo Luis Adrián
Published: April 2019

Hoy como en el pasado, muchos museos etnográficos o de las culturas en el mundo, continúan escenificando un orden social establecido hegemónicamente. En ellos el discurso normativo de la museología eurocentrista logra imponerse a partir de la concepción de su estructura narrativa, la selección de sus objetos de exhibición y la puesta en escena, fortaleciendo así el pensamiento neoliberal que promulga la diversidad cultural como la sumatoria de culturas que comparten un mismo territorio, sin contradicciones, sin asimetrías, sin tensiones sociales, en una “paz social” aparente y en una relación natural con el entorno. El Museo de Quai Branly-Jean Chirac es un buen ejemplo de ello.
