Authors:   Assistant Prof., ITER, SOA University, Bhubaneswar, Odisha, India, Bose* Bidula
Published: November 2019

Sand-bentonite mix is commonly used as liner material or backfill material in landfill sites. Bentonite belonging to group of montmorillionite clay provides higher density and less void ratio to lessen permeability of liner layer mixed with sand. This mix is inevitable and economical where soil nearby landfill site have sandy soil .Many literatures provided geotechnical aspects of using this mix.In this present study, the grain size distribution analysis and compaction of sand–bentonite mixture for 10%,20% and 30% bentonite mix is studied to propose economic and less permeable liner material with lower shrinkage. Locally available sand from different river , Odisha (India) was mixed with different proportions of commercial sodium bentonite. The following research output presented here elaborately show the effect of clay particle on compaction, Relative Density, Coefficient of uniformity,Coefficient of curvature, permeability by gradually adding commercial Sodium Bentonite 10% by weight upto 30%. The result show that there is a significant improvement in MDD and OMC of Sand-Bentonite mix along with decrease in void ratio. The grain size alteration eventually helped to increase the dry density and reduced void ratio will enhance the scope of this mix to be used as liner layer in landfill system.

It is well known fact that light is associated with its neighbouring spectrum of Ultraviolet ray (UV ray). UV has deleterious effects upon living and non-living objects. In order to avoid this bad effect of UV some simplified methods to need to try out. Experimentation has been carried out with Incandescent lamp, Conventional Fluorescent lamp, Compact Fluorescent Lamp (CFL) and Light Emitting Diode (LED) lamps and separately UV content as well as illuminance at various distances have been measured. UV-measurement has been made by UV meter made through world reputed make- Konica Minolta, Japan and illuminance is measured by Lux-Meter. The observations have been shown in the main body of the paper which shows successful results as per expectations. The system can be adopted for Museum lighting where important archives can be saved from bad effects of emitted UV from the ambient light sources. This simple methodology can thus be adapted for indoor application in Museum lighting/ Heritage building lighting where archives can be easily conserved.

In the study of evaluation of infant brain development, the segmentation of obtained MR images is an important step. When compared with the MR images of adult brain it is difficult to identify the different regions in infant brains with that of the methods used for the analysis of adult brains. This is due to the size difference of the brain and the differences in the properties of the brain tissues. So, for analyzing these MR images it requires manual interaction with the images resulting in the bias of the results. For this problem we propose another approach for the segmentation of neonatal brain MR images. This method doesn’t require any manual interaction and produces unbiased results. Our algorithm segments the different layers (right hemisphere, left hemisphere, cerebellum, brain stem) and the different tissues like sub cortical gray matter, Militated & un mylinated gray matter and cerebrospinal fluid, resulting in the better understanding of the development of different parts of the brain. Our algorithm can be used for the analysis of MR images of infant brains of age as less as 3to6 months.

The paper is devoted to practical information security aspects in the corporate system. Particular attention is paid for the ensuring access control problem for corporate confidential information. Solving this problem involves identifying a person trying to gain unauthorized access to the corporate system and identification of a authorized user committing illegal actions. The paper shows that a person's keyboard handwriting is determined by behavioural characteristic, which is very difficult to imitate. This means that the person identification based on the keyboard handwriting analysis is the most reliable. It is necessary to consider the possibility of accidental uncontrolled change user’s keyboard handwriting settings when it works. Such changes can be caused by changes in physiological or emotional state. Using neural networks enables to perform analysis of handwriting keyboard considering these changes at the real time. Thus, the artificial neural networks using makes it possible considerably improves the security of corporate confidential information protection from authorized user committing illegal actions. Existing methods and algorithms for user identifying by his keyboard handwriting are focused on using a multilayer perceptron. However, FAM architecture and capabilities analysis of adaptive resonance theory has identified advantages such as the ability to form associative pairs and map the rules of fuzzy inferences to clusters of neural networks in this category. Considering these characteristics was decisive in choosing the neural network intelligent system for users identification by his keyboard handwriting style. As a result of the research proposed generalized architecture Corporate System Users Identification by the Keyboard Handwriting, based on the use of Cascade ARTMAP. The scheme of rules formation in Cascade ARTMAP and the knowledge base formation scheme of Users Identification Intelligent System by Keyboard Handwriting are proposed.

Question Answering is one of the most common applications for data acquisition. Although the majority of text-mining applications strive to improve the user experience and the tools used to find appropriate answers, the problems still exist because the web content is constantly increasing. The Questions Classification (QC) task is one of the main tasks in improving the classification system is to classify types of questions in the text mining application. A large number of QC methods are introduced to help resolve classification problems, most of which are bag of words approaches. In this project, we propose a QC system that uses Parts of Speech (POS) Tagger and Named Entity Recognition (NER) Tagger from the Stanford core Natural Language Processing (NLP) to classify the questions correctly. We started by cleaning the data by removing the available labels in the questions then we proceed by tagging the questions by splitting words and tagging each and every words in the input question with the POS Tagger. After this step, we will convert them into a pattern without changing the structure of the question. Then we proceed by tagging the question with NER Tagger. Finally, we will do confirmation process for certain question types which is performed by confirming question type module to make the system work efficiently.

Aim. The work was performed with the purpose to study a hemolytic activity in the culture of S.pyogenes under the inhibitory action of millimolar concentrations of zinc ions.Materials and methods. Suspensions of S.pyogenes bacteria which contained 108 CFU/ml were sown by the lawns into the standard Petri dishes coated with the supplemented Blood Nutrient Agar. 30 min later the salt solutions of zinc or copper which contained the metals at the concentrations ranged between 5 x 10-3 M to 5 x 10-1 M were added by the 5 μl drops on the surfaces of the lawns with use of 36-channel stamp replicator. Then the dishes with bacterial cultures were incubated for 24 hrs at 37°C followed by measuring diameter of the area of culture growth inhibition and of the area of inhibition of hemolysis. The study was performed with use of controls towards measuring the state of bacterial cells obtained from different zones of the areas.Results. In presence of the zinc ions concentrations ranged between 50 to 500 mM the area of the growth inhibition of S.pyogenes was surrounded on the lawn of the bacterial culture by the area of the inhibition of hemolysis where the growth inhibition of S.pyogenes was not registered. Copper ions did not form such an area of the hemolysis inhibition.Conclusion. Inhibitory action of zinc ions on the hemolytic S.pyogenes activity in the culture seems to be specific and reversible, and is discussed in a context of the antivirulent zinc ions properties.

Aim. Isolation of ribonucleoprotein (RNP) of an attenuated rabies virus, develop schemes for immunizing animals with RNP-based preparations and determine the most effective scheme that allows obtaining serum with a high antibody titer to the RNP.Materials and methods. We used the transplantable cell line Vero, the strain rabies virus «Moscow 3253 Vero», adapted for reproduction on Vero, rabbits of the chinchilla breed. In order to obtain serums containing antibodies to the RNP of the rabies virus, experimental schemes have been proposed for immunizing animals with RNP, including with adjuvants: polyoxidonium and colloidal gold. The dynamics of the accumulation of antibodies to the RNP of the rabies virus in the blood serum of experimental animals was studied by dot-immunoassay.Results. The target component (RNP of the rabies virus) was isolated directly from the cytoplasm of the Vero cell culture infected with the rabies virus according to the modified M. Dastkhosh (2014) method, lyophilized and used in the development of preparations for immunizing experimental animals. In the study of the dynamics of the formation of antibodies to RNP of the rabies virus by the method of dot-immunoassay, the effectiveness of an adjuvant is established — colloidal gold nanoparticles ranging in size from 15 to 17 nm, the use of which makes it possible to increase the antibody titer by 2 times.Conclusion. The results obtained are of interest for further research related to the design of diagnostic products and the development of methodological techniques using such preparations.

The construction of cantilever retaining wall uses reinforcement as part of the retaining wall’ structure. Reinforcement of the construction of the Retaining Wall is carried out on construction if there is a need for additional reinforcement on the structure or carrying out reconstruction on the structure of the retaining wall. Research on the use of starter rebar uses chemical epoxy, which is used to reconstruct the retaining walls. Soil investigation is carried out because the soil in this structure acts as a load, then this soil parameter is calculated as a lateral force on the wall that makes the rolling moment, and sliding. The land load also acts as a counter weight behind the wall. The study of the use of back reinforcement on the structure of cantilever type retaining wall uses D19-170 as the main reinforcement in the tensile area and D16-170 in the compressed area. Reinforcement for used D13-170.

Road is a land transportation infrastructure that covers all parts of the road, including complementary buildings and equipment intended for traffic. Road Structure Improvement is one project that aims to improve the quality of roads. As the object of work to be studied is the widening of the sp. Ujung Aji - Limits of the City of Kabanjahe. Road construction with a flexible layered pavement with cover or without overlays is usually often damaged such as: cracks, hollows, bumps on the road surface. In other conditions it is often seen that the grooves of the former water flow to the subgrade are visible. The situation is more extreme and often occurs, namely the road surface peels to reach the foundation layer, so that the aggregate looks scattered. This study uses the direct observation method in the widening project of Jalan Simpang Ujung Aji - Bts. Kabanjahe City. This research was carried out at the time of laying and compaction of the bottom road foundation layer such as Base B and Base A. Activities carried out included data collection, data processing, analysis and observations in the Laboratory. The results of the filter analysis of rough gradations are good, which is in the middle between the given gradation boundaries, does not coincide and does not come out of the given gradation limit. Based on aggregate filter analysis data, it can be concluded that the results of the gradation of aggregate class A percent are retained and passed the filter in accordance with the general specifications of Bina Marga 2010 revision 3 and according to class A aggregate planning. the specimen is completely waterless, so the weighing results in the right balance.

Published: November 2019

O território rural brasileiro é marcado pelo amplo número de estabelecimentos agropecuários familiares, sendo estes responsáveis por boa parte da produção de alimentos. O objetivo do artigo foi de verificar a produção agrícola e pecuária dos estabelecimentos agropecuários da agricultura familiar do município de Roque Gonzales, estado do Rio Grande do Sul, do ano-safra agropecuário de 2016-2017. A pesquisa foi realizada com os agricultores familiares a partir de entrevistas semiestruturadas com a coleta de dados referentes a produção, produtividade, área, renda e estabelecimentos. Para a análise empregou-se a estatística descritiva e multivariada. Os estabelecimentos familiares concentraram as atividades no campo agrícola, com evidência a produção do milho, soja e bovino de leite. Em relação a área, a produção agrícola se sobressaiu, com predominância a soja, cria/recria de bovinos e bovino leiteiro. Quanto ao valor monetário sublinha-se a hegemonia agrícola frente a pecuária, mas com destaque a bovinocultura de leite, soja e milho. Os dados referentes a principal cultura remetem a interpretação de que os agricultores familiares possuem tendência na produção de commodities, especificamente da soja. No tema da área, facilmente se visualizou o perfil familiar tendo como critério as pequenas extensões produtivas. Na relação entre valor/área, a hortifruticultura se avultou sobre as demais, o que permite admitir que não necessariamente a maior extensão de área corresponda ao maior retorno financeiro. Milho, soja e bovino de leite conformaram uma estrutura agrária ímpar, um sistema heterogêneo que a remarca em um padrão produtivo associado a monocultura, porém, de caráter familiar.

Penelitian ini berupaya menjawab beberapa masalah : Bagaimana pelaksanaan jual beli karet di desa Betung Kecamatan Lubuk Keliat Kabupaten Ogan Ilir, bagaimana tinjauan fiqih muamalah terhadap kecurangan jual beli karetdi desa Betung Kecamatan Lubuk Keliat Kabupaten Ogan Ilir. Sejalan dengan masalah yang telah dirumuskan, maka penelitian ini bertujuan untuk mengetahui pelaksanaan jual beli karetdi desa Betung Kecamatan Lubuk Keliat Kabupaten Ogan Ilir, untuk mengetahui tinjauan fiqh muamalah terhadap kecurangan jual beli karet di desa Betung Kecamatan Lubuk Keliat Kabupaten Ogan Ilir.

Untuk mengetahui masalah tersebut penulis menggunakan jenis data kualitatif, dengan sumber data primer yaitu merupakan data pokok yang diperoleh dengan menggunakan studi lapangan mewawancarai sebagian penjual dan pembeli karet yang melaksanakan jual beli karet di desa Betung. Sedangkan data sekunder diambil dari dokumentasi dan literatur yang berhubungan dengan masalah yang diteliti, seperti buku-buku perpustakaan yang ada kaitannya dengan permasalahan yang dibahas. Adapun teknik pengumpulan data yaitu observasi, wawancara dan dokumentasi. kemudian data yang telah terkumpul dianalisa secara kualitatif dengan menggunakan instrumen analisis deduktif interpretatif.

Dari penelitian ini ditemukan, bahwa pelaksanaan jual beli karet di desa Betung dilakukan setiap hari Rabu, ada yang menjual karet dengan sistem bebas dan ada pula yang menjual karet secara terikat pada toke karet. Dari hasil penelitian ada pembeli karet (toke karet) yang melakukan praktek kecurangan melalui timbangan karet dan ada sebagian penjual karet (petani karet) yang menambahkan batu dan tanah ke dalam kepingan karet untuk menambah berat timbangan ketika dijual. Dalam fiqh muamalah jual beli tersebut tidak sah karena bertentangan dengan syarat dan rukun jual beli yang telah ditetapkan dalam syariat Islam. Selain bertentangan dengan syariat Islam melakukan kecurangan merupakan perbuatan zalim kepada orang lain dalam urusan hartanya dan memakan harta mereka dengan cara yang batil. Walaupun hanya sedikit, harta yang didapatkan dengan jalan berbohong, menyembunyikan kecacatanatau mengurangi timbangan adalah harta yang haram.
