A agregação do solo pode representar um parâmetro que relaciona o manejo à qualidade do solo para às terra preta arqueológica (TPA). O objetivo do trabalho foi estudar a variabilidade espacial dos agregados e matéria orgânica do solo em terra preta arqueológica sob pastagem. Os dados foram coletados em uma grade amostral com as dimensões de 80 x 56 m, com espaço entre os pontos de 08 m, e total de 88 pontos amostrais. As amostras de solos foram coletadas nas profundidades 0,0-0,05, 0,05-0,10 e 0,10-20 m, para as avaliações: diâmetro médio geométrico (DMG), classe de agregados > 2,00mm, 2-1 mm, índice da estabilidade dos agregados (IEA) e matéria orgânica do solo (MO); após análise exploratória e geoestatística, os modelos foram ajustados aos semivariogramas para cada atributo. Os resultados mostraram que a porcentagem de agregados na classe > 2,00 mm apresentou valores acima de 80% indicando maior resistência à desagregação. Os altos teores de MO no solo influenciaram a formação e estabilização dos agregados do solo.

Published: August 2018

O estudo objetivou caracterizar a estrutura de uma área ribeirinha na bacia do rio Taperoá, semiárido paraibano. O levantamento abrangeu um trecho ao longo do riacho Farias (7°25’33” S e 36°29’21” W; 454-470 m de altitude), onde estabeleceu-se 51 parcelas contíguas de 10 X 20 m (1,02 ha), distribuídas em três faixas paralelas ao longo do curso d’água. Os critérios de inclusão utilizados foram amostrar os indivíduos arbustivo-arbóreos, vivos e mortos em pé, com diâmetro do caule ao nível do solo (DNS) ≥ 3 cm e altura total ≥ 1 m. Assim, em cada parcela procedeu-se a medição do diâmetro, altura e anotado o nome da espécie. Foram calculados parâmetros gerais da comunidade (densidade total, área basal total), parâmetros relativos e absolutos das espécies (densidade, frequência e dominância) além do valor de importância (VI) e valor de cobertura (VC). Determinou-se também os índices de diversidade de Shannon e de equabilidade de Pielou. Foram amostrados 1.838 indivíduos distribuídos em 41 espécies, 34 gêneros e 20 famílias. A área basal total da vegetação ribeirinha foi de 15,6 m².ha-¹. As três espécies mais importantes em VI foram Poincianella pyramidalis (Tul.) L.P.Queiroz, Croton blanchetianus Baill. e Combretum leprosum Mart. Os valores de diversidade e equabilidade foram 2,18 nats.ind.-1 e 0,59 respectivamente. Um reduzido número de famílias e de espécies representa a maior parte de indivíduos amostrados. As espécies de Caatinga apresentaram os maiores valore nos parâmetros fitossociológicos. O elevado número de espécies com¬ um indivíduo por hectare contribuiu para uma maior riqueza florística.

Published: August 2018

Diante da complexidade de monitorar, avaliar e planejar o manejo de fragmentos urbanos para garantir sua sustentabilidade, o uso de índices é um modo rápido de obtenção de dados relevantes, informações mensuráveis em campo e de parâmetros para realização de comparações e análises diagnósticas. O presente estudo teve por objetivo adaptar um índice de integridade biótica para uso em Floresta Estacional Semidecidual, bem como testar sua eficiência no diagnóstico da integridade biótica de fragmentos florestais inseridos em matriz urbana. Este índice é composto por 11 indicadores ecológicos e foi aplicado em 23 remanescentes florestais localizados na cidade de Sorocaba/SP. Dentre as áreas selecionadas, 15 foram classificadas com baixa integridade e 8 como integridade regular, entretanto, se destacam entre estas 4 áreas que obtiveram pontuação equivalente à mais de 60% do índice. Ao verificar a eficiência dos indicadores que compõem o índice, destaca-se a necessidade de realizar algumas adaptações quanto aos utilizados e suas classes de integridade, contudo, os resultados obtidos foram considerados satisfatórios, uma vez que geraram diferenciações na classificação da integridade biótica das áreas analisadas que são condizentes com o observado em campo. Constatou-se que a maior parte dos fragmentos estudados apresentam ameaças à sua sustentabilidade, evidenciando que a maioria destas áreas carece de esforços voltados para seu manejo e conservação a fim de que continuem exercendo suas funções ecológicas a longo prazo.

Two-sided Estimates of Thermal Conductivity Coefficient of a Porous Body Skeleton
Authors: Zarubin V. S. , Novozhilova O. V. , Sergeeva E. S.
Published: August 2018

Porous composite materials are widely used in engineering as structural and heat-insulating materials. The presence of pores in such materials is due to both the technology of their manufacture and the operating conditions.

One of the most important factors in the process of designing products from a porous composite is the complex of thermophysical characteristics of the material. This characteristic determines the application area of the material.

Among the thermophysical properties the leading role is played by the coefficient of thermal conductivity. This coefficient for some porous materials can be determined experimentally, however, in order to reduce the time and resources needed, a theoretical study of this characteristic is more relevant.

Theoretical investigation of the thermal conductivity coefficient of a porous composite allows us to predict its possible values depending on the composition of the material and its porosity. Such information about the composite is necessary at various stages of working with the material from its preparation to the construction of a structure from it.

There are many works devoted to approaches to the theoretical evaluation of the coefficient of thermal conductivity of a porous material. However, due to a significant spread of its values, an actual task is to construct guaranteed two-sided estimates of the possible values of this material characteristic.

As is well known, there are some difficulties in constructing lower estimates of the properties of a porous material. In this paper, to overcome this difficulty, a modification of the structural model of the porous body was used in conjunction with the dual formulation of the stationary heat conduction problem in an inhomogeneous solid.

The modification of the structural model of a porous body in this paper is as follows: a hollow spherical particle is replaced by a solid sphere with an equal external radius. The solid sphere in turn is represented by a composite ball consisting of an inner ball of some conventional material and an outer spherical layer of the carcass material of the porous body. The equivalent thermal conductivity of the material of the inner ball is to be determined.

The modification of the structural model of the porous body proposed in the work allowed to obtain two-sided estimates of the possible value of this coefficient. Also, the obtained estimates were compared with unimprovable upper bound for this characteristic.

The obtained results will allow us to predict two-sided estimates of the thermal conductivity coefficient of perspective heat-insulating and structural porous materials.

Published: August 2018

Madelung’s disease also called benign symmetric lipomatosis is a rare disorder of unknown etiology. The disease affects almost exclusively middle-aged men with a history of multi-year alcohol abuse. The major symptom is presence of non-encapsulated benign fat masses, especially in the area of the head and neck. Limited head and neck movement, dysphagia, and dyspnea may appear as well.

The diagnosis is clinical and is supported by imaging methods, often elevated hepatic enzymes in blood serum, and histological examination with finding of mature adipose tissue without signs of proliferation. Therapeutic methods involve liposuction or excision which is a method of choice nowadays.

In this article the authors review current knowledge, research state, and present five cases of the Madelung’s disease occurring within the last 10 years at the Clinic of Otorhinolaryngology and Head and Neck Surgery in Martin, Slovakia.

Authors: Zedan Adnan Jayed , Maulood Hend Jamal
Published: August 2018

The present study attempts to represent the behavior of shallow foundations under the effect of eccentric inclined loading in terms of the main criteria of design which are the ultimate bearing capacity, permissible settlement, horizontal displacement and tilt. Due to the square shape of the analysed foundations, three dimensional finite element analysis are used. Elastic-perfectly plastic behavior of soil and rigid of foundations was adopted using Mohr-Coulomb criterion, 15-Node wedge elements were used to model and represent the soil and 5-Node linear elements with three degree of freedom to model and represent the foundations in used program PLAXIS 3D TUNNEL version 1.2.The results of analysis were presented in the form of pressure-settlement, pressure-horizontal displacement and pressure-tilt characteristics. Then the ultimate bearing capacity of the foundations were gotten and compared with (Meyerhof, 1956) and (Saran & Agrawal, 1991), a good agreement was found between them. Using the data obtained from the analysis, non-dimensional correlations have been developed for predicting the values of settlement, horizontal displacement and tilt of eccentrically-obliquely loaded foundations. These relationships can be used by the engineers.

Authors: Hussein Omar A.
Published: August 2018

Predictions are reported for mixed convection using various types of nanofluids over forward-facing double steps in a duct. The continuity, momentum and energy equations are discretized and the simple algorithm is applied to link the pressure and flow fields inside the domain. Different types of nanoparticles Al2O3, CuO, SiO2 and ZnO, with different volume fractions in range of 1-4% and different nanoparticles diameter in the range of 20 – 80nm in base fluid (water) were used. Numerical investigations are conducted using finite volume method. In this study, different parameters such as the geometrical specifications (different steps heights in the range of h1= 0.01m-0.04m and h2 = 0.03m-0.06m for FFS) are used. Different Reynolds numbers in the range of 50-2000 (laminar flow) are investigated to identify their effects on the heat transfer and fluid characteristics. The results indicate that SiO2-water has the highest Nusselt number followed by Al2O3-water,Cuo-water and ZnO-water. The Nusselt number increases as the volume fraction increases but it decreases as the nanoparticles diameter increases. The velocity magnitude increases as the density of nanofluids decreases. The recirculation region and the Nusselt number increase as the step height, Reynolds number, and the volume fraction increase.

Authors: Thabet Hassaan Th. H. , Allu Ahmed A.
Published: August 2018

This paper describes a modern approach for the protection of transmission lines to ensure their safety against the faults occurred in power systems. Our approach uses a Programmable Logic Controller (PLC) to realize a transmission line as an over current protection relay. A conditioning circuit was designed, implemented and tested to collect data obtained from Hall Effect sensors which convert them to suitable analog values compatible with PLC's inputs. Results obtained by our PLC control system are very similar to those obtained by the conventional relays but more efficient. An Automatic Reclosing System (ARS) for remote faults is also included in this approach. Our PLC control system and its algorithm are illustrated in this paper also. This approach is designed to be used in electrical networks laboratories as an educational unit in electrical departments of engineering collages and technical institutes; it can be used also in real power systems through suitable interfacing facilities.
Efficient T-OOFDM System to Mitigate the Dispersion of Long-Haul Optical Fiber Channel at WANs
Authors: Ahmed Mohammed Shweesh
Published: August 2018

Due to its attractive features, the utilization of fiber optics as a transmission medium with various applications is increased rapidly. In despite, when signals are transmitted with high data rates through ultra-long haul distances of single-mode fiber (SMF), which is usually used at wide area networks (WANs), the nonlinear dispersion of signals is raised. This phenomenon leads digital pulses to interfere with the adjacent pulses. In this paper, an optical orthogonal frequency division multiplexing based T-transform (T-OOFDM) system is proposed to mitigate the effect of fiber dispersion significantly and reduce the peak-to-average power ratio (PAPR) of the transmitted signal when compared with conventional optical OFDM (OOFDM) system. Simulations results confirmed by the analytical analysis demonstrated that the detrimental effects arising from fiber channel dispersion on the subcarrier orthogonality of the transmitted signals can be efficiently minimized by using T-OOFDM system. Moreover, the peak of the transmitted signal will be considerably reduced whilst preserving the average power of signals.

Assessment and Evaluation for Learners in Multilingual Societies at Technical Civil Engineering Ekasakti University
Authors: Marmai Ungsi A.O. , Suri Elda Martha
Published: August 2018

This analysis examines some of the problems that are faced by teachers and students in the teaching and learning of English for special purposes (ESP) in multilingual nations. A survey recently found that although 98 percent knew that English was the sole language of instruction at the institution, only 49 percent expected to study English as a subject in any form as part of their curriculum. Many students looked upon English as a subject of study necessary only to gain entrance into the university, and had little motivation to study it past the secondary level. Other problems faced by teachers and students include the multilingual background of the learners, lack of cooperation from teachers of other subjects, the need to import language materials, poor levels of language teacher training, and large class sizes. An alternative approach to ESP is suggested, one in which the learner's native language and other languages in the learner's environment play a major role in tertiary education. The importation of culturally and educationally irrelevant materials is noted along with the urgent need for teacher training reform.

Authors: Voloshina O.
Published: August 2018

The interest in learning a foreign language in all countries of the world has increased significantly. This is dictated by the laws and pace of development of the world economic system, as well as the goals and objectives of the education system as a whole. In this regard, the question arises about the quality of teaching a foreign language. In Ukrainian education most of the teaching tasks are given to students not in a test form. Basically this is a question, a task, an exercise. The test is a more appropriate qualitative and objective way to evaluate different types of speech activity in a foreign language. Testing in Ukraine is a method of controlling the knowledge of external independent assessment, and students must be adapted to this method.Key words: foreign languages, test technologies, control, foreign language competence, foreign language communicative competence, elementary classes.
A TENTATIVE SEARCH FOR CONFLATION IN THE EPISTLE TO GALATIANS (2:5; 4:14)
Authors: Dyatlik T.
Published: August 2018

The article presents a tentative search for conflation in the Epistle to Galatians (2:5; 4:14). The purpose of this article is paving the methodological way for further research into conflation by the tentative search for candidates for conflation in the Epistle to Galatians. The variant «οις ουδε» is not a conflation of «οις» and «ουδε», since it is the primary reading from which the two other variants originated.  Nevertheless, taking into consideration probable scribal and patristic grammatical impovements or doctrinal alterations, the history of the transmission seems to exhibit the transmissional phenomenon of difflation. The variant «μου τον» is not a conflation of «μου» and «τον». In the tentative conclusion there have been indicated several factors to be considered on which the variant «υμων τον» can be supposed to be a conflation of the primary reading «υμων» and the variant «τον».  Key words: conflation, Epistle to Galatians, New Testament, Corpus Paulinum manuscript.

Authors: Zagidulin R. V. , Zagidulin T. R. , Osipov K. O.
Published: August 2018

The effect of changes in the chemical composition and structure of structural steel on the results of magnetic control of the stress-strain state of the metal is studied using data on the field strength of the residual magnetization. It is shown that data of magnetic control reveal changes in the stress-strain state of the metal in the region with significant changes in the structure and chemical composition. This approach is based on the control of the electrical conductivity of the metal, which is highly sensitive to changes in the structure, phase and chemical composition of structural steel. In the field of significant changes in the electrical conductivity of the metal, additional experimental studies should be carried out, including optical metallography and X-ray spectral analysis of metal samples, the results of which are analyzed in combination with the obtained data of magnetic control of the stress-strain state of the metal and thus determine the reason for the origin of the stress state in the local area of the steel product, which is important in the technical examination of steel products and elements of metal structures. It has been shown experimentally that a significant increase in the carbon content in the chemical composition of structural steel changes the electrical and magnetic parameters, but almost does not touch the magnetoelastic sensitivity of the field strength of the residual magnetization of the metal that matches theoretical considerations. We assume that this is also valid for constant and random impurities in the chemical composition of steel, if change in their content does not significantly affect the magnetoelastic sensitivity of the field strength of the residual magnetization of the metal.
On the method of ultrasonic control of mechanical stresses
Authors: Kurashkin K. V.
Published: August 2018

A method of ultrasonic control of the mechanical stresses which takes into account the heterogeneity of the material structure and does not require unloading of the structure or using reference samples is considered. The procedure is based on echo-method of measuring time of the bulk elastic wave propagation and determination of the relative values ν31 and ν32 related to the material structure and mechanical stresses. It is shown that stresses violate the linearity of the relationship observed between the parameters in the absence of the mechanical stresses in the rolled material. This effect formed a basis for developing a method of the deviator stress determination. The purpose of the study is to demonstrate the main advantages of the developed method against the known ultrasonic techniques used for evaluation of the mechanical stresses, give theoretical grounds to the effect which allows taking into account the heterogeneity of the material structure, and also to exemplify the procedure. An analytical expression is derived using bulk elastic wave velocity in an orthotropic material composed of cubic crystallites and an assumption on the existence of simple proportional relationship between the coefficients of the orientation distribution function in rolled metal. Presented results of the mathematical modeling confirm the experimentally observed linear dependence between the parameters ν31 and ν32 in the absence of mechanical stresses. The results of evaluating residual stresses in a welded steel plate are presented as an example of the applicability of the developed procedure. Data of ultrasonic technique and data of strain gage measurements are compared. The features of the described method of stress determination are marked and the applicability limits are specified.
Um polvorinho de marfim com cenas cinegéticas
Authors: Rodrigues Tiago
Published: August 2018

Com este artigo pretende-se estudar um olifante luso-africano realizado na Antiga Serra Leoa no século XVI, que no século seguinte foi transformado em polvorinho. Do olifante em marfim conserva-se um fragmento com 18 cm, enquanto as ferragens que o modificaram medem 7 cm. Esta é uma das raras peças de marfim luso-africano que se encontra disponível no mercado da arte português. Neste artigo pretende-se realçar a estima que estas peças possuíam nos inícios da época moderna na Europa, sobretudo pelas suas associações ao mundo masculino da caça e da montaria áulica. Em comparação com outros exemplos do mesmo género, esta peça apresenta uma decoração segmentada em diferentes zonas. Acena de autorreferência sugere que os artesãos africanos valorizavam o seu trabalho enquanto mestres do marfim, assunto que também pretendemos desenvolver.

Qualquer relação jurídico-laboral com vínculo de emprego público comporta, sempre, para ambos os contraentes, uma complexidade de direitos e obrigações, à semelhança do que acontece no direito privado. Neste tipo de relações jurídicas, o acesso aos tribunais torna-se fulcral até porque, muitas vezes, poderácolocar-se em causa o respeito por direitos fundamentais. Daí que neste ramo do direito, o acesso à justiça tenha que ser, acima de tudo, efetivo. Alcançaremos uma justiça efetiva, de maior qualidade, se as pretensões trazidas a juízo forem julgadas por tribunais especializados, com recursos humanos vocacionados e sensibilizados para determinado tipo de questões jurídicas.

Kasus nefrolithiasis ini ditemukan pada seekor red eared slider (RES) atau di Indonesia dikenal dengan nama kura-kura Brazil, secara tidak disengaja ketika hewan tersebut diperiksa secara radiografi untuk melihat morfologi normalnya. Kura-kura telah dipelihara selama satu tahun oleh pemilik tanpa ada keluhan apapun. Kura-kura tersebut dipelihara di dalam kolam bersama dengan ikan, pakan yang diberikan pemilik adalah ikan kecil dan sayur. Riwayat kura-kura sebelum dipelihara pemilik tidak diketahui. Radiografi dilakukan melalui 3 standar pandang, yaitu dorsoventral, laterolateral dan craniocaudal. Hasil radiografi dari ketiga standar pandang tersebut menunjukkan adanya massa radiopaque di bagian kanan dan kiri abdomen kura-kura. Pemeriksaan ultrasonografi (USG) dilakukan sebagai diagnosa penunjang. Hasil yang didapat dari pemeriksaan USG ini adalah ditemukan massa hiperekhoik pada ginjal.

A very large segment of the population in India has not been
affected by the process of post-independence economic development.
According to one estimate, in 1983, around 300 million people, or 40
percent of the total population, were living below the poverty line,
while more than 100 million people were living in severe destitute
conditions. Infant mortality, which is an important indicator of
undernourishment, is more than three times the rate in Sri Lanka and
China. This is not a satisfactory state of affairs but it represents a
significant improvement over time. While population has increased from
355 million in 1949-50 to 775 million in 1985-86, foodgrain output has
almost tripled to 151 million tonnes during the same period. Most of the
other agricultural crops have followed a similar pattern of growth,
implying an increase in the per capita availability of
domestically-produced agricultural products over time. The main source
of agricultural growth since the Sixties has been the increasing use of
modern inputs, which have contributed to higher yields and to
multi-cropping patterns. However, while the green revolution diminished
poverty, it adversely affected the distribution of land, leading to the
concentration of resources in fertile areas and benefiting more the
richer farmers. Furthermore, the growth of population combined with slow
urbanization has increased the population pressure on land. The land-man
ratio has been declining over time and the increase in employment
opportunities outside agriculture, both in urban and rural areas, which
is vital for reducing poverty, has not been significant enough to alter
the employment pattern. This suggests that it would be impossible to
wipe out poverty in the foreseeable future by altering prices or raising
production alone, despite evidence that the price index and the
production of agricultural products have a direct influence on
poverty.
Listeria monocytogenes: A CONSIDERABLE PATHOGENIC MICROORGANISM OF CONCERN IN MINIMALLY PROCESSED FRUITS AND VEGETABLES
Authors: Tuhumury Helen C D
Published: August 2018

The increasing demand of minimally processed fruits and vegetables signify a challenge to make them stable and safe to be consumed. The processing of this type of product may contribute higher risks of food borne illnesses. One of the foodborne pathogens in minimally processed fruits and vegetables is Listeria monocytogenes. The importance of understanding the characteristics of L. monocytogenes will help to determine how this microorganism occurs, grows, and survives in minimally processed fruits and vegetables. Proper and suitable methods to reduce L. monocytogenes so that it can not pose a significant risk to cause disease therefore are able to be determined according to the model of the growth and survival of L. monocytogenes in minimally processed fruits and vegetables.
