Trong nghiên cứu trước, chúng tôi đã phân lập được chủng vi khuẩn B. thuringiensis serovar kurstaki (Btk) MSS1.1 có khả năng thủy phân chitin cao. Chủng Btk MSS1.1 đã được dùng để tạo chế phẩm kháng nấm gây bệnh thực vật và diệt côn trùng gây hại, tuy nhiên hiệu suất còn thấp và khó nâng cao hiệu quả sinh tổng hợp của chitinase - enzyme chìa khóa quyết định hiệu quả phòng bệnh của chế phẩm. Để khắc phục hạn chế này các nhà nghiên cứu áp dụng công nghệ protein tái tổ hợp để sản xuất chitinase qui mô công nghiệp. Hướng đi này giúp nâng cao hiệu suất sinh tổng hợp chitinase đồng thời dễ dàng tinh sạch và thu hồi enzyme hơn so với việc sử dụng chủng tự nhiên. Nhằm mục đích thu được lượng lớn enzyme có hoạt tính cao, chúng tôi tiến hành biểu hiện và thu nhận chitinase tái tổ hợp (rChiA) từ chủng Btk trong E. coli. Gene mã hóa chitinase của chủng Btk được thiết kế vào vector biểu hiện pET28b(+) tại vị trí EcoRI và XhoI. Protein tái tổ hợp được biểu hiện ở dạng tan và vẫn duy trì hoạt tính sinh học. Hoạt tính của chitinase tái tổ hợp tăng 1,26 lần so với chitinase tự nhiên. rChiA được tinh sạch thành công bằng sắc k. ái lực sử dụng cột Probond Nikel Resin. Kết quả thử nghiệm cho thấy, chitinase tái tổ hợp có khả năng kháng 2 loại nấm gây bệnh thực vật là Fusarium oxysporum và Rhizoctinia solani nhưng không gây ảnh hưởng đến Mucor sp. Ngoài ra, chitinase tái tổ hợp còn làm tăng hoạt tính diệt sâu tơ (Plutella xylostella) và sâu khoang (Spodoptera litura) của protein tinh thể thu nhận từ chủng B. thuringiensis tự nhiên. Khi sử dụng kết hợp rChiA với protein tinh thể từ chủng SP10.6 đã rút ngắn thời gian gây chết từ 72 giờ xuống còn 48 giờ (gây chết 100% đối với sâu tơ và 84,3% đối với sâu khoang), đồng thời giá trị LC50 giảm 8,04 % và 6,80% lần lượt đối với sâu tơ và sâu khoang.

Published: December 2018

Through composting process, biosolid wastes are gradually transformed into compost material which can be used as soil fertilizer. Among microorganisms involved in composting process, fungi play important roles because they break down complex substrates, such as ligno-cellulose. Recently, PCR-DGGE technique has been considered as a useful tool for analysis of fungal diversity in environmental samples. Among other factors, primer set selection is necessary for successful of the PCR-DGGE analysis. There are several PCR primer sets targeting fungal variable regions of 18S ribosomal DNA (rDNA) and internal transcribed spacer (ITS) for the use in community analyses, however there exist just few reports on efficacy of these primers in studying fungal communities in compost materials. In this study, four different primer sets were tested, including EF4/Fung5 (followed by EF4/NS2-GC), EF4/ITS4 (followed by ITS1F-GC/ITS2), NS1/GC-Fung, and FF390/FR1-GC. Extracted DNA from compost materials often contains co-extracted humic substances and other PCR inhibitors. Therefore, the primers were tested for (i) tolerance to the PCR inhibitors presenting in the DNA extracted from compost materials, and (ii) efficacy and specificity of the PCR. The results showed that of the four primer sets, only FF390/FR1-GC achieved both criteria tested whereas the other three did not, i.e. primer EF4/ITS4 had low tolerance to PCR inhibitors, primers EF4/Fung5 was low in PCR amplification efficacy, whereas primers EF4/ITS4 created unspecific products. DGGE analyses of PCR products amplified with the primer set FF390/FR1-GC showed single bands for reference pure cultures Penicillium sp., Aspergillus sp., and Trichoderma sp., as well as distinctly separated bands for the fungal communities of three different composting materials. Thus, the primer set FF390/FR1-GC could be suitable for studying structure and dynamic of fungal communities in compost materials.
POPULATION DIVERSITY OF XANTHOMONAS ORYZAE PV. ORYZAE CAUSING BACTERIAL LEAF BLIGHT IN RICE FIELDS OF CAN THO
Authors: Tuan Tran Quoc , Hao Lam Tan , Khoa Nguyen Dac
Published: December 2018

Bacterial leaf blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a destructive disease in rice fields. Can Tho is one of the most important rice-growing areas in the Mekong Delta, which is vulnerable to climate change, making the disease more damaging in this region. Deployment of resistance genes is considered an economic and eco-friendly approach to control the disease. However, Xoo exists in different races with diverse reactions on different resistance genes. Thus, for effective management of BB, it is essential to understand the diversity of contemporary Xoo population to deploy appropriate resistance genes in rice fields. This study aims at assessing the Xoo population diversity (race composition) in rice fields of Can Tho using pathogenicity reactions on the near-isogenic lines (pathotypes) in combination with insertion sequence-PCR technique using J3 primer (genotypes). Among 132 isolates obtained from BB-infected leaf samples collected from six rice-growing areas of Can Tho, 126 isolates were identified as Xoo using PCR with the specific primers XOO290F/R. The contemporary Xoo population in Can Tho was composed of four races including two classic standard races (5 and 7) and two newly emerged ones (5* and 5**) of which races 5 and 5* were the most predominant. Seven haplotypes were identified in the four races and haplotypes I and III were predominant, accounting for 50.79% and 40.48%, respectively. The combination of the pathotypic and genotypic analyses showed genetic variations in races 5 and 5*. These results could be used for deployment of appropriate BB resistance cultivars in rice fields of Can Tho.

Published: December 2018

Organic waste is gradually degraded during composting process, producing carbon dioxide, water, heat, and humus, the relatively stable end product. The degradation process is carried out by living organisms, of which fungi appear to have the most important role since they break down tough debris (cellulose, lignin, and other resistant materials), enabling other microorganisms to continue the decomposition process. The objective of this study was to isolate and identify the fungi associated with large scale municipal biosolid waste composting process in Vietnam. In this study, we have isolated 10 morphologically different fungal strains from the composting materials, and classified based on morphological characteristics and 18S rDNA sequences. The results showed that these fungal strains belonged to four different genera, including Aspergillus, Penicillium, Monascus, and Trichoderma. The results would be a useful reference for further studies of diversity, and functions of fungi that involved in municipal biosolid waste composting process in Vietnam environmental conditions.

Natural products were proved to have inhibitory effect on the nitro-oxidative stress. The aim of the study was to evaluate the effect of Mahonia aquifolium (MA) flowers extract upon nitro-oxidative stress in acute experimental inflammation. The extract was prepared by repercolation method. Acute experimental inflammation was induced with turpentine oil (0,6ml/kg b.w. i.m.). MA extract was given for 7 days. Were used 6 groups (n=5) of male Wistar rats: Groups 1-3 were with acute inflammation and treated with MA dilutions (100%, 50%, 25%); Group 4 was acute inflammation control; Group 5 was negative control; Group 6 was acute inflammation treated with diclofenac (10mg/kg b.w. p.o). In day 8 nitro-oxidative stress was evaluated by measuring serum nitrites and nitrates (NOx), Total oxidative stress (TOS), Total antioxidant capacity (TAC), Oxidative stress index (OSI), Malondialdehyde (MDA) and Thiols (SH). MA reduced OSI and TOS, increased SH, and had no important effect on TAC, NO and MDA. Compared to MA, Diclofenac was a stronger inhibitor of TOS and OSI, and had a smaller effect on SH. Mahonia aquifolium flowers extract had inhibitory effect on the oxidative stress, without influencing NO and lypoperoxides production, the effect being smaller than that of Diclofenac.

Authors: Farokhah Fiqih Aisyatul , Habsari Sri Kusumo , Mugijatna Mugijatna
Published: December 2018

Sexuality is an interesting yet controversial topic in Indonesian culture. The discourse of morality makes it taboo in public. In patriarchy culture, women are always placed as an object of sexuality. In Islam, it also becomes an important topic discussed in Alquran. Now the phenomenon of sex exploitation spreads through the oppression of women’s body. The capitalist uses it to construct a discourse of women’s beauty, to exploit women’s body, and to use seduction to obtain some profits. One of the examples is sales promotion girl (SPG) phenomenon. This reality has influenced some novelists to raise this theme as their main novel topic. One of them is Indah Hanaco. This paper reveals the representation of women’s sexuality in Indah Hanaco’s novel entitled “The Curse of Beauty”. Indah Hanaco had been influenced by the phenomenon of SPG surroundings. Many SPG had trapped in prostitute caused by their sociality lifestyle constructed by the capitalist. They were forced to sell their body to get money to beautify their appearance. It became very important because it was an asset for them. Actually, it was not only about economic motif, but also psychological motif which affected their consciousness. This phenomenon was also widely discussed from the Islamic perspective, especially in the Alqur’an.

Resumo: Fundamentado na Teoria da Agência, neste estudo teve-se por objetivo principal analisar a relação entre a remuneração dos gestores de 48 empresas participantes do Ibovespa e seus indicadores de desempenho, utilizando-se dos testes de correlação, análise de correspondência múltipla e regressão. Os resultados evidenciaram a inexistência de correlação significante entre a remuneração dos diretores-executivos e os indicadores Lucro por Ação e Retorno sobre o Patrimônio Líquido. Embora os níveis de significância encontrados para a correlação entre remuneração dos diretores-executivos e desempenho apontem para a existência de correlação somente para os indicadores Q de Tobin e a variação do Valor de Mercado, destaca-se a necessidade de continuidade dos estudos sobre o tema, uma vez que, em razão da separação da propriedade e controle e dos consequentes conflitos de agência entre proprietários e gestores, as empresas precisam adotar mecanismos para que o alinhamento entre esses agentes possibilite a criação de oportunidades que possam potencializar seus resultados.Palavras-chave: Teoria da Agência. Remuneração de gestores. Indicadores de desempenho.Executive compensation and performance indicators in companies participating in the Bovespa Index Abstract: According to the Agency Theory, the present study aims at analyzing the relation between remuneration for managers of 48 companies listed on the Bovespa Index and their respective performance indicators. This research employed the correlation, the multiple correspondence analysis and regression tests. The obtained results made it possible to verify the inexistence of significant correlation between the remuneration of managers and the performance indicators Earnings per share and Return on equity. Although the levels of significance found for the correlation between the variables executive compensation and performance indicators point at the existence of correlation only for Tobin’s Q and Market value variation, the continuity of studies stands out because, it is known that, due to the separation of property from control and resulting agency conflicts between owners and managers, companies need to adopt devices so that the alignment of these agents makes it possible to create opportunities to boost results.Keywords: Agency Theory.

Authors: Irsyadi Achmad Naufal , Dinurriyah Itsna Syahadatud
Published: December 2018

The progress history of Black Africans in America remains a slice of the history of minority struggle in the world of inferiority. Racism becomes a brand topic in every sector of Blacks live in America. War and act of reformation as ways against racism are almost routinely done by Black Americans to reach their civil rights as Americans. Although the war against racism has ended, but racism atmosphere can still be felt, and it seems to have been felt by Ernest J. Gaines in his novel entitled A Lesson Before Dying. Therefore, this writing would like to analyze and describe hegemonic discrimination by White Americans. Hegemonic discrimination is a new phenomenon for Black Americans in the Southern. This theoretical foundation refers to the theory of Hegemony by Antonio Gramsci that is applied to see how discriminative hegemony is implemented smoothly and comfortably.

ASYMPTOTICS OF VALUE FUNCTION IN MODELS OF ECONOMIC GROWTH
Authors: Bagno Alexander Leonidovich , Tarasyev Alexander Mikhailovich
Published: December 2018

Asymptotic behavior of the value function is studied in an infinite horizon optimal control problem with an unlimited integrand index discounted in the objective functional. Optimal control problems of such type are related to analysis of trends of trajectories in models of economic growth. Stability properties of the value function are expressed in the infinitesimal form. Such representation implies that the value function coincides with the generalized minimax solution of the Hamilton–Jacobi equation. It is shown that that the boundary condition for the value function is substituted by the property of the sublinear asymptotic behavior. An example is given to illustrate construction of the value function as the generalized minimax solution in economic growth models.

Authors: Mishachev Nikolay Mikhailovich , Shmyrin Anatoliy Mikhailovich
Published: December 2018

Neighborhood structures (digraphs of a special kind) can have vertex or relational sets of equipping variables. Vertex variables correspond to the vertices of the structure, while the relational ones correspond to the arcs. The article describes an algorithm for the canonical transformation (declusterization) of the relational structures into the vertex ones. This transformation establishes a connection between two types of control metasystems on neighborhood structures.

ABOUT ONE STOCHASTIC HARVESTING MODEL OF A RENEWED RESOURSE
Authors: Rodina Lyudmila Ivanovna
Published: December 2018

We investigate the models of dynamics of the harvested population, given by the control systems with impulse influences depending on random parameters. We assume that in the absence of harvesting population development is described by system of the differential equations x ̇=f(x) and in time moments kd, d>0 from population are taken some random share of a resource ω(k)=(ω_1 (k),…,ω_n (k) )∈Ω, k=1,2,…, that leads to sharp (impulse) reduction of its quantity. Considered resource x∈R_+^n is non-uniform, that is or it consists of separate kinds x_1,…,x_n, or it is divided on n age groups. In particular, it is possible to assume that we make harvesting of n various kinds of fishes between which there are competition relations for food or dwelling places.We describe the probability model of a competition of two kinds for which we receive the estimations of average time benefit from the resource extraction, fulfilled with probability one.

THE THEOREM OF BOHL–PERRON ON THE ASIMPTOTIC STABILITY OF HYBRID SYSTEMS AND INVERSE THEOREM
Authors: Simonov Pyotr Mikhailovich
Published: December 2018

We consider an abstract hybrid system of two equations with two unknowns: a vector function x that is absolutely continuous on each finite interval [0,T], T>0, and a sequence of numerical vectors y. The study uses the W-method N.V. Azbelev. As a model, a system containing a functional differential equation with respect to x is used, and a difference equation with respect to y. Solutions spaces are studied. For a hybrid system, the Bohl–Perron theorem on asymptotic stability and the converse theorem are obtained.

Authors: Sumin Mikhail Iosifovich
Published: December 2018

We consider the regularization of the classical Lagrange principle and the Pontryagin maximum principle in convex problems of mathematical programming and optimal control. On example of the “simplest” problems of constrained infinitedimensional optimization, two main questions are discussed: why is regularization of the classical optimality conditions necessary and what does it give?

Authors: Tyrsin Alexander Nikolaevich , Surina Alfiya Adgamovna
Published: December 2018

The risk model of multidimensional stochastic systems is described. It is based on the hypothesis that the risk is characterized by probabilistic properties of components of multidimensional stochastic system which are used as risk factors. The case of the Gaussian stochastic systems is investigated. The model of risk monitoring allows to estimate the current risk of system and the contribution of all its components. Models of risk management are optimizing tasks. As the target functions the conditional minimum of risk and achievement of the given level by it can be used at minimum changes of probabilistic characteristics of the system.

Authors: Cuno Silke , Bruns Lina , Tcholtchev Nikolay , Lämmel Philipp , Schieferdecker Ina
Published: December 2018

This paper presents the results of a recent study that was conducted with a number of German municipalities/cities. Based on the obtained and briefly presented recommendations emerging from the study, the authors propose the concept of an Urban Data Space (UDS), which facilitates an eco-system for data exchange and added value creation thereby utilizing the various types of data within a smart city/municipality. Looking at an Urban Data Space from within a German context and considering the current situation and developments in German municipalities, this paper proposes a reasonable classification of urban data that allows to relate the various data types to legal aspects and to conduct solid considerations regarding technical implementation designs and decisions. Furthermore, the Urban Data Space is described/analyzed in detail, and relevant stakeholders are identified, as well as corresponding technical artifacts are introduced. The authors propose to setup Urban Data Spaces based on emerging standards from the area of ICT reference architectures for Smart Cities, such as DIN SPEC 91357 “Open Urban Platform” and EIP SCC. Thereby, the paper walks the reader through the construction of an UDS based on the above mentioned architectures and outlines all the goals, recommendations and potentials, which an Urban Data Space can reveal to a municipality/city.
Microscopic Change in Hardened Cement Paste Due to High-Speed Impact
Authors: Sakai Yuya , Sikombe Ivwananji , Watanabe Keiko , Inoue Hiroyuki
Published: December 2018

Impact load was applied to hardened cement paste (HCP) specimens using a gas gun to investigate microscopic changes in the specimens and develop a better response model of concrete subjected to impact load. Plasma emission was observed at the moment of impact at 420 m/s and the colour of the portion near the impact point turned brighter. This brighter portion was analysed, and it was observed that the pore structure was coarser compared to the other portion; however, the results of thermogravimetry and X-ray diffraction analysis were similar. A possible reason is that the generated heat was instantaneous and the rate of the temperature increase in the HCP decreased due to evaporation of water in the HCP. These results indicate that during impact at a few hundred m/s, porosity increase due to heat effect is more dominant than porosity decrease due to mechanical compaction.
Correlations between Air Permeability Coefficients and Pore Structure Indicators of Cementitious Materials
Authors: Sakai Yuya
Published: December 2018

Correlations between the air permeability coefficient and various pore structure indicators in cementitious materials were examined to determine the pore structure indicator that best evaluated air permeability using data from previous studies of air permeabilities and pore structures. The determination coefficients of air permeability with total pore volume, critical pore diameter, and ordinary threshold pore diameter were low, although these have often been used as indicators. The median and threshold pore diameters obtained by percolation theory showed high determination coefficients. The equation using the threshold pore diameter better estimated the air permeability coefficient than the Katz–Thompson equation.

Published: December 2018

The issue of unemployment has bedeviled the development of many countries especially when the youths who are trained in various skills of human endeavor find it difficult in getting job opportunities. This research work has focused on the impact of unemployment with specific attention to Nigeria. The country over the years from 2009 to date witnessed a series of attacks by the Boko Haram terrorist group whose membership mostly are the youths. The main objective of this research is to examine the impact of unemployment as it causes psychological trauma, frustration and aggression thereby resulting to a state of insecurity. The work made use of qualitative research design through the conduct of interviews. The work also made use of other sources such as journal publications and internet sources. The findings drawn from this research reveal that some of the youths who engage in terrorist attacks against the Nigerian state are unemployed while some could be due to poverty and illiteracy. The issues raised could cause psychological trauma to the victims especially those whose relatives lost their lives as well as those who are internally displaced. The work, therefore, recommends a new public policy framework as a strategy in resolving the conflict in order to sustain peace and security of the country.
