Periodic Maximum Entropy Random Structure Models for High-Entropy Alloys
Authors: Feng Wen Qiang , Zheng Shu Min , Qi Yang , Wang Shao Qing
Published: June 2017

Periodic chemically homogenized high-entropy alloy structures are constructed according to maximum entropy principle. The method can efficiently generate equimolar and non-equimolar high-entropy alloy atomic structures. Nine high-entropy alloys are simulated based on the constructed models using density functional theory techniques. The calculated lattice parameters are consistent with the available experimental data. The calculated enthalpies of mixing are more negative than the values estimated by using Miedema model, due to severe lattice distortion. The lattice distortion parameters were calculated. The results showed that fcc structure tend to stable with smaller and bcc structure with larger. The bulk modulus of Al1.5CoCrNiFe high-entropy alloys was fitted and the value is consistent with the available experimental data.

Authors: Wang Jia Xing , Wang Xu Ming , Guo Hui , Zhao Ai Min , Wei Liu
Published: June 2017

The tensile and impact tests were used to study the mechanical properties under different temperatures of 300 mm large-scale angle steel at different positions, especially the tensile strength, yield strength, total elongation and impact toughness in the range of-40 oC to 20 oC. The results showed that different regions had great differences in the microstructures and impact toughness, in which the size of edge region was the smallest and the impact toughness was the best. However, the coarsened grain of heat affected zone at weld region had deteriorated to the low temperature impact toughness. When the impact energy was 34 J, the ductile-brittle transition temperature of weld, center, vertex and edge were-7.2 oC, -33.0 oC, -31.5 oC and far less than-40 oC, respectively. Meanwhile, because the banded structure was detrimental to the ductility, the elongation of rolling direction was lower than vertical direction. The strength of weld region was higher than other locations, but the elongation was obviously decreased.

Published: June 2017

Based on the stress-strain curves at the temperature of 300-450 °C with strain rate of 0.01-1 s−1 by hot compression tests, the empirical dynamic recrystallization models for the semi-continuous AZ31magnesium alloy were developed. The dynamic recrystallization evolution during the seamless tube extrusion of the AZ31 Mg alloy was simulated by numerical method with the derived models and validated by experiment measurements. The results show that at certain extrusion speed the influence of the extruding temperature on the dynamic recrystallization fraction was significant. With the increase of the extruding temperature the volume fraction of dynamic recrystallization increase obviously. The predicted dynamic recrystallization fraction was in an excellent agreement with the experimental results.

Published: June 2017

Microstructure and tribological characteristics of WC/Ni-based plasma transferred arc welding (PTAW) overlays have been investigated. WC/Ni-based composite overlays were deposited under same conditions with different percent of WC particle (20-70 wt.%) in the 304L stainless steel. Reciprocating wear tests were undertaken according to the ASTM G133-05 standard. Microstructure and surface micrographs of the cross-section and worn surfaces were characterized. The results indicated that the wear rate decreased with the increasing percent of WC particle, revealing no visible decrease in wear when the percent of WC particle reached more than 50 wt.%. Coating with 50 wt.% WC particle possessed a fine abrasion resistance due to a homogeneous microstructure. Furthermore, at a low concentration (20 wt.% to 40 wt.%), the wear mechanism were adhesive wear and oxidation wear, whereas in 50wt.% WC particle, the main wear mechanism were adhesive wear and abrasive wear. In the case of high concentration of WC particle (above 50 wt.%), the predominant wear mechanism was three-body abrasive wear.

Published: June 2017

Objective: A comparative study between threaded and plain dental implant designs was performed to find out a new criterion for dental implant selection. Materials and Methods: Several dental implant designs with a systematic increase in diameter and length were positioned in a cylindrical-shaped bone section and analyzed using finite element method. Four loading types were tested on different dental implant designs; tension of 50 N, compression of 100 N, bending of 20 N, and torque of 2 Nm, to derive design curves. Results: Better stress distribution on both spongy and cortical bone was noted with an increase in dental implant diameter and length. With the increase in dental implant side area, a stress reduction in the surrounding bones was observed, where threaded dental implants showed better behavior over the plain ones. Conclusions: Increasing value of ratio between dental implant side area and its cross-sectional area reduces stresses transferred to cortical and spongy bones. The use of implants with higher ratio of side area to cross-section area, especially with weak jaw bone, is recommended.

Authors: Ravikanth Reddy
Published: June 2017

ABSTRACT

Schwannoma, also called neurilemmoma, is a benign peripheral nerve sheath tumor. Most common locations are flexor surfaces of the extremities, neck, mediastinum, retroperitoneum, posterior spinal roots, and cerebellopontine angle. Pleural schwannomas are extremely rare neoplasms of the thoracic cavity. To the best of our knowledge, till date, <20 cases have been reported. Herein, we report a case of primary benign pleural schwannoma in an elderly 60-year-old female in whom the pleural mass was discovered incidentally on computed tomography chest. The patient was subjected to left posterolateral thoracotomy; pleural mass was resected which showed histopathological and immunohistochemical features of schwannoma.

Objectives: The present study was undertaken to evaluate salivary cortisol levels in children of smokers and nonsmokers and thereby establishing the relationship between cortisol levels in response to anxiety in children based on their father's habit of smoking. Materials and Methods: The study population aged between 8 and 10 years includes two groups. Group 1 is comprised 20 children of cigarette smokers and Group 2 is comprised 20 children of nonsmokers. The passive drooling technique was used to collect unstimulated saliva from the children using a sterile container. Salivary cortisol levels were evaluated using Enzyme-linked Immunosorbent Assay method. The obtained data were subjected to statistical analysis using SPSS software and paired t-test. Results: Higher mean salivary cortisol levels were found in children of smokers compared to children of nonsmokers and the difference between them was significant statistically (P < 0.05). Higher salivary cortisol levels were found in females compared to males and the result was significant statistically (P < 0.05). Conclusion: This study has proved that the smoking habit of the father has a negative influence on the anxiety levels of their children.

Authors: Kesim Bertan , Sagsen Burak , Aslan Tugrul
Published: June 2017

Objective: The aim of this study was to compare the incidence of root cracks after root canal instrumentation with thermomechanically processed nickel-titanium (Ni-Ti) files with different instrumentation kinematics. Materials and Methods: A total of 150 extracted mandibular premolars with mature apices and straight root canals were divided into five groups and used in this study. In Group 1, 30 teeth were prepared using hand K-files and assigned to control group, Group 2 was instrumented using K3XF Rotary files (SybronEndo, Glendora, CA, USA) with continuous rotary motion. The teeth in Group 3 were instrumented by ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland) rotary files which make asymmetric rotary motion, In Group 4, teeth were instrumented by RECIPROC (VDW, Munich, Germany) with reciprocation motion and in Group 5, teeth were instrumented by Twisted File (TF) Adaptive (SybronEndo, Orange, CA, USA) files that use combination of continuous rotation and reciprocation motion (n = 30/per group). All the roots were horizontally sectioned 3, 6, and 9 mm from the apex with a low speed saw under water cooling. Then, the slices were examined through a stereomicroscope to determine the presence of dentinal microcracks.Results: For the apical (3-mm) and coronal (9-mm) sections, the ProTaper Next and TF Adaptive produced significantly more cracks than the hand files, RECIPROC, and K3XF (P < 0.05). There was no significant difference between the experimental groups and control group at the 6-mm level (P > 0.05). Conclusions: Within the limitations of this in vitro study, all thermal-treated Ni-Ti instruments and hand files caused microcracks in root canal dentin.

Authors: Mariscal Méndez Araceli , Ramírez Miranda Cesar Adrián , Pérez Sánchez Alfonso
Published: June 2017

La preocupación por solventar el problema del hambre ha traído a escena los conceptos de seguridad y soberanía alimentaria, originados en distintos contextos. Siendo el objeto de este escrito la revisión documental y análisis de estos dos conceptos, establecer sus diferencias, así como a la reflexión sobre la importancia de la pequeña producción para solventar el problema del hambre. Se concluye que la producción campesina abona a una soberanía alimentaria desde un sustento cultural y económico que se traduce en una lógica de reproducción social desde la comunalidad, lo que puede contribuir a ver una forma distinta de desarrollo que la impuesta por el sistema hegemónico.

Published: June 2017

There has been growing discourse related to the importance of the scholarship of educational development (SoED), but less discussion related to clearly defining principles for guiding engagement in SoED or contextualizing SoED within literature related to the scholarship of teaching and learning (SoTL). Expanding upon Felten’s (2013) principles for SoTL, as well as evolving discourse related to principles of educational development (e.g., Gibbs, 2013; Taylor & Rege Colet, 2010; Timmermans, 2014), this paper presents seven principles for SoED. Two additional principles (transforming practice and reflective practice) are added to Felten’s principles to further contextualize SoED in relation to educational development and SoTL. Three cases are provided to illustrate educational development, SoTL, and SoED within the context of these principles. The interrelationships between educational development, SoTL, and SoED are complex. While SoED offers many opportunities for further legitimizing the individual and collective practices in educational development, it also presents many additional tensions and questions for further research.
On parle de plus en plus de l’importance de l’avancement des connaissances en pédagogie (ACP), mais on parle moins d’une définition claire des principes qui guident l’engagement en ACP ou de la contextualisation de l’ACP dans les publications de la recherche consacrée à l’avancement des connaissances en enseignement et en apprentissage (ACEA). Pour élargir la portée des principes pour l’ACEA présentés par Felten (2013), ainsi que celle du discours évolutif lié aux principes de la pédagogie (voir Gibbs, 2013; Taylor & Rege Colet, 2010; Timmermans, 2014), cet article présente sept principes pour l’ACP. Deux principes supplémentaires (transformation de la pratique et pratique réflective) sont ajoutés aux principes de Felten afin de contextualiser davantage l’ACP par rapport à la pédagogie et à l’ACEA. Trois cas sont présentés pour illustrer la pédagogie, l’ACEA et l’ACP dans le contexte de ces principes. Les relations entre la pédagogie, l’ACEA et l’ACP sont complexes. Alors que l’ACP offre de nombreuses possibilités pour rendre plus légitimes les pratiques individuelles et collectives en pédagogie, il présente également de nombreuses tensions et des questions supplémentaires qui pourront faire l’objet de davantage de recherche.

Partnerships with students are considered one of the principles of good Scholarship of Teaching and Learning (SoTL) practice. However, not all partnerships are equally successful. What characteristics are common to successful partnerships and what preparatory elements can lead toward more successful partnerships? In this article, our team of graduate students, educational developers, and faculty members engage in detailed self-reflection on our past and ongoing SoTL projects as an inquiry into what it means to be in a successful student-faculty/staff partnership. Using thematic analysis, we identify and describe four distinct domains that can shape partnerships: (1) motivations to participate, (2) challenges, (3) power, and (4) definitions of success. The article concludes with a set of questions to stimulate initial and ongoing conversations between partners to guide new partnerships in defining the parameters for success in their proposed collaboration.
Les partenariats avec les étudiants sont considérés comme l’un des principes de bonne pratique de l’Avancement des connaissances en enseignement et en apprentissage (ACEA). Toutefois, tous les partenariats ne connaissent pas le même succès. Quelles sont les caractéristiques communes des partenariats réussis et quels sont les éléments préparatoires qui peuvent aboutir à des partenariats mieux réussis? Dans cet article, notre groupe, consistant d’étudiants de cycles supérieurs, de conseillers pédagogiques et de professeurs, se lance dans une auto-réflexion détaillée sur nos projets passés et présents en ACEA qui constitue une enquête sur ce que cela signifie de faire partie d’un partenariat réussi entre étudiants, professeurs et membres du personnel. Par le biais de l’analyse thématique, nous identifions et décrivons quatre domaines distincts qui façonnent les partenariats : 1) la motivation à participer, 2) les défis, 3) le pouvoir et 4) les définitions de la réussite. En conclusion, nous posons un groupe de questions pour stimuler les conversations initiales et continues entre les divers partenaires afin de guider les nouveaux partenariats à définir les paramètres menant à la réussite dans leur collaboration proposée.
EMISSÃO DE GASES DE EFEITO ESTUFA E PROPOSTA DE PROJETO PARA COMPENSAÇÃO: UM ESTUDO DE CASO E-COMMERCE
Authors: Nunnenkamp Christian Horst , Corte Ana Paula Dalla
Published: June 2017

O objetivo geral deste trabalho foi estimar a emissão de gases de efeito estufa (GEEs) de uma empresa de peças de decoração infantil e-commerce utilizando a metodologia GHG Protocol e propor um projeto de compensação ambiental. Foi criada uma metodologia para estimar as emissões do Escopo 3, considerando a posição geográfica do destinatário final para onde os produtos comercializados foram enviados. O estudo resultou em uma emissão total de 201,77 tCO2e e de 4,88 tCO2 biogênico, no âmbito dos três escopos. O projeto de compensação baseou-se em sequestro de carbono, por meio de plantio florestal. Com base em um modelo existente com sete cenários de plantios, com o uso de espécies de Eucalyptus, seria necessário um maior número de mudas para absorver a mesma quantidade de GEEs, seguido das espécies nativas e de Pinus. Contudo, por conta de a região escolhida para o plantio ser diferente da região do modelo original, existe a possibilidade de que alguns cenários propostos não se desenvolvam conforme o esperado, devido, principalmente, às diferenças de clima e solo. Mesmo que o plantio florestal seja efetivo, é importante ressaltar que as árvores calculadas se referem somente ao ano base do levantamento, ou seja, novas árvores devem ser plantadas todos os anos para a devida compensação. A partir das análises dos objetivos, concluiu-se que o trabalho em conjunto da redução com a mitigação das emissões através de plantio florestal é muito importante para o combate ao aumento da temperatura terrestre.

O objetivo deste trabalho foi mapear e quantificar as áreas com plantações de Eucalyptus spp. no estado do Paraná. Para tal, fo­ram utilizados dados de áreas geoespacializadas de povoamentos florestais com classificação visual de imagens de satélite e validados com base em 988 pontos observados em campo. A área total plantada com Eucalyptus no estado totalizou 340.315 ha, o que representa 1,71% da superfície do estado. A região Centro-Sul possui 61,91% do total plantado com Eucalyptus no estado, a qual concentra a maior parte do parque industrial flo­restal. Vinte e cinco municípios do estado possuem mais da meta­de da área plantada com Eucalyptus, esses municípios encontram-se na região Centro-Sul, com destaque para o núcleo de Ponta Grossa, com mais de 42,27% da área plantada no estado, segui­do pelos núcleos de Curitiba, Guarapuava, União da Vitória, Irati, Laranjeiras do Sul e Pato Branco. O Paraná é o estado com a quin­ta maior área plantada com Eucalyptus, em que o município de Telêmaco Borba, núcleo regional de Ponta Grossa, possui a maior área plantada no estado, com cerca de 45 mil hectares.

Os senadores do Paraná no contexto da Revolução de 1930: capitais políticos e familiares
Authors: Granato Natália Cristina
Published: June 2017

O presente trabalho procura trabalho procura discutir quais são os capitais políticos e familiares dos senadores do Paraná da legislatura anterior à Revolução de 1930 (que assumiram o mandato a partir de 1928) e posterior ao mesmo acontecimento histórico (eleitos em 1933). Entendemos tal conjuntura como um processo de “modernização conservadora”. Ao analisar os cinco senadores desta delimitação temporal, a saber: Carlos Cavalcanti de Albuquerque, Marins Alves de Camargo, Caetano Munhoz da Rocha (estes pertencentes à legislatura anterior ao movimento de 1930), Antônio Jorge Machado Lima e Flávio Carvalho Guimarães, (eleitos no período pós-1930), pretendemos identificar quais sãos os atributos sociais, políticos e familiares de suas trajetórias, averiguando quais foram os impactos que a Revolução de 1930 provocaram nas suas carreiras. Tendo como referência algumas indagações de Pierre Bourdieu a respeito dos acúmulos de capitais pelos agentes sociais, refletiremos sobre as mudanças e permanências que a representação do Paraná no Senado presenciou com a Revolução de 1930.
Relações de parentesco como alavancagem para conversão de capital político
Authors: Barros Júnior José Lázaro Ferreira
Published: June 2017

Por meio de uma analogia com o mercado financeiro, busca-se corrigir uma inconsistência no modelo de análise proposto pelo autor, em 2011, na dissertação “Desempenho eleitoral nas eleições proporcionais de 2008 em Curitiba”, sobre a instrumentalização das relações pessoais no processo de conquista do voto. Na época, a classificação elaborada a partir de entrevistas qualitativas com candidatos eleitos para a Câmara de Vereadores colocou lado a lado, com diferentes qualidades de capital social (de ligação, de ponte, de conexão, solidariedade comprometida e imperativo moral), as relações de parentesco e o protagonismo nos meios de comunicação social. Entendia-se que esses sete tipos de relações pessoais podiam ser convertidas em capital político. Contudo, feita a reanálise do trabalho de campo, percebeu-se que os dois últimos, em especial as relações de parentesco, não concorrem com os outros tipos de capital social – pelo contrário, são evocadas para catalisar a conversão daqueles laços sociais em desempenho eleitoral. No mercado financeiro, um procedimento semelhante é chamado de alavancagem, quando uma pessoa toma empréstimo para realizar uma segunda operação de capitais. Neste artigo é sugerido que a alavancagem baseada nas relações de parentesco influencia a política, notadamente marcada por assimetrias de informação, como uma operação em que o nome da família, por exemplo, é oferecido como garantia da transação – no caso, da representação política.

Prosopografia dos diretores do BNDES (1952-2016)
Authors: Estevinho Gloria
Published: June 2017

O que se propõe para este artigo é a análise de quem foram os Diretores do BNDES (Banco Nacional do Desenvolvimento Econômico e Social), uma instituição criada em 1952 e voltada para financiar, a longo prazo, a realização de investimento em todos os segmentos da economia de âmbito social, regional e ambiental, até os dias de hoje. Pretendemos verificar se estes indivíduos formam, em seu conjunto, uma elite política e administrativa nesta instituição e quais foram as formas de acesso a esse cargo: por meio de mérito/carreira tecnocrata ou por vias de parentesco/nepotismo, ou ambos. O método de análise utilizado para se compreender os diretores do BNDES será o prosopográfico. A partir da prosopografia busca-se entender o perfil geral destes diretores e de que maneira isto influenciaria nas diretrizes adotadas por esse banco. Portanto, o problema que se coloca é identificar esta “elite política/administrativa”, fundada sobre pesquisas empíricas. Esse estudo se faz necessário e se justifica, pois pouco ou nada se sabe sobre quem foram e qual o perfil destes diretores do BNDES. Esta análise específica a que se propõe este trabalho pode contribuir para a discussão mais ampla sobre o que é o Brasil e sua formação e mesmo o processo de formação dessa elite promovido no século XX pelo governo Vargas.
Rio Branco Sport Club e Paranaguá/PR: Representações Políticas

Published: June 2017

A pesquisa “Futebol além das quatro linhas: Identidade e Pertencimento no Rio Branco Sport Club – Paranaguá/PR” buscou símbolos de pertencimento dos torcedores ao Município, considerando a cultura como a base para a promoção de identidades e, estas, as que resultam em pertencimento com a sua afirmação e representação. Através da leitura histórica, da análise de discursos de manifestações da internet e de entrevistas foram identificadas as ligações políticas. A representação política do Município está relacionada aos dirigentes do Rio Branco, sendo este um fator histórico do Clube. A relação entre a política e o Clube é apresentada na forma de elogio aos políticos pelo que fizeram ao Rio Branco ou de crítica, pela falta de apoio da prefeitura, expressando dependência. Por vezes, as representações de ambos se confundem, onde as ações que cabem ao Clube são atribuídas aos políticos. Além disso, a Torcida Organizada manifestou apoio à candidatos a prefeito e vereador. As ações da Torcida Organizada e do Clube com o Município estabelecem relações de poder social dentro e fora do campo a partir dos papéis que assumem nas representações. A diretoria e os políticos representam o poder no Clube e no Município, respectivamente, mantendo as estruturas suas manutenções no poder. A torcida na relação estabelecida com um e outro assume o trabalho de base para manutenção dos poderes, criticando-os sobre o que não fazem, fazendo.
Mulheres candidatas à vereadora em Umuarama/PR nas eleições de 2016: expectativas e perspectivas da participação feminina na política
Authors: Silva Rafael Egídio da , Almeida Thaís
Published: June 2017

Este texto tem por objetivo investigar a percepção das candidatas a vereadora acerca da participação feminina na política local, aproveitando o pleito de 2016. Questionamos a importância da participação das mulheres em cargos políticos em Umuarama-PR, e quais são os fatores que influenciam para a pouca participação das mesmas nos cargos, a partir da análise da fala das candidatas. Observa-se que a participação feminina ainda é muito inferior ao número de homens no poder. No tocante ao pleito eleitoral de 2016, Umuarama contou com 77.467 eleitores, sendo que deste total são aproximadamente 47% de homens, e 53% de mulheres. Em relação aos vereadores, foram 121 candidatos disputando 10 vagas na Câmara local, sendo 39 mulheres. A metodologia do projeto realizou a entrevista das candidatas a respeito de sua percepção acerta da expectativa e perspectiva da participação da mulher local. Do total de candidatas, obteve-se o retorno de 11 entrevistas. Além da análise dos dados obtidos, e as entrevistas com as candidatas, o trabalho visa contribuir com a investigação do histórico da participação feminina na Câmara de vereadores local. Observando tamanha desigualdade entre homens e mulheres na política, e considerando a grande participação masculina, nota-se que esta situação apenas é um retrato da nossa sociedade, e percebe-se que a questão de gênero pode influenciar na participação das mulheres em cargos representativos, sendo o sexo feminino como o menos valorizado.
Classification of traumatic brain injury severity using retrospective data
Authors: Rogers Sandra , Trickey Amber W.
Published: June 2017

Objective: Accurate classification of traumatic brain injury (TBI) severity is essential to brain injury research. TBI heterogeneity complicates classification of the injury; is a significant barrier in the design of therapeutic interventions; and results in retrospective data which is difficult to translate. The objective of this study is to describe the differences in two current tools used in the classification of TBI severity, the Glasgow Coma Scale (GCS) and the head Abbreviated Injury Score (AIS), using retrospective data to compare their performance.Methods: Using correlational and descriptive statistics, this study examined two TBI severity classification methods across a large sample of TBI patients (N = 56,131), who were treated at level I and level II trauma centers in the United States and were included in the 2010 National Sample Program (NSP) of the National Trauma Data Bank (NTDB®).Results: The study population was 67% male, 67% non-Hispanic white, treated most often in trauma centers in the South (38%), with blunt trauma (93%) and from non-motor vehicle collisions (MVC’s) (56%). Observation of the AIS classification system demonstrated that it tends to over-score TBI severity compared to the GCS classification. The methods (GCS & AIS) had a weak, inverse relationship with a correlation coefficient (Pearson’s r) of -0.3980, which was significant at p < .001.Conclusions: The current study addressed the difficulties associated with categorizing TBI severity when analyzing retrospective data.  Although AIS is commonly used to classify severity in retrospective data when GCS is unavailable, the relationship between the two scales is relatively unknown. Results show that AIS and GCS are more closely related for severely brain injured patients but in cases of mild and moderate injury, AIS is less predictive of GCS. Since they are often used in conjunction in identifying brain injured severity in retrospective data, researchers cannot be certain that the tools are similarly classifying mild, moderate, and severe injuries. This study reinforces the need for additional TBI severity classification methods, such as neuroimaging techniques and biomarkers.
Export Effect of China’s Outward FDI: Provincial Panel Data Analysis
Authors: Wang Xiaohui
Published: June 2017

China’s direct investment overseas reaches US$170.11 billion and is US$44 billion more than the actual use of foreign investment, which makes China a net capital exporter. Large scale of Outward Foreign Direct Investment also has a great influence on the export. This article made an estimation on the export effect of Outward Foreign Direct Investment through fixed effect model and Generalized Method of Moment based on the provincial panel data from 2004 to 2014.

Бид мал аж ахуйн (МАА-н) үйлдвэрлэл эрхлэгчид болон хэрэглэгчидийн хөдөө аж ахуйн зохистой дадлын (ХААЗД)-ийн талаархи мэдлэг, хэрэглээг нэмэгдүүлэхийн тулд сүүний үхрийн аж ахуй (АА) эрхлэгчдэд ХААЗД-ийн өөрийгөө үнэлэх шалгуурыг танилцуулан АА-н нэгжийнх нь үйл ажиллагааг өөрөөр нь үнэлүүлсэн юм (GlobalGAP, 2014 version 2.1, Dairy). Судалгаанд УБ хотын 61-ын гарам орчимд байрлаж нийслэл хотын иргэдэд тогтмол сүү нийлүүлдэг нэр бүхий дөрвөн АА нэгж хамрагдав. Сүүний үхрийн АА эрхлэгчид нийт 8 бүлэг 46 шалгуурын дагуу өөрийн АА-н технологийн үйл ажиллагааг 1-5 оноогоор үнэлэв. Судалгааны дүнгээс үзэхэд АА-н нэгжүүд 1-8-р бүлэг асуулт буюу шалгуур тус бүрт нийт авах онооны дөнгөж 21,25-75,00%-ийг авч байгаа нь сүү үйлдвэрлэгч бага, дунд хэлбэрийн аж ахуйд дадал болсон технологийн үйл ажиллагаа байхгүй байгааг илтгэнэ. Мөн АА-н нэгж тус бүрээр оноог дундажлан үзэхэд 41,25-51,67%-ийн үнэлгээ авч байгаа нь сүү үйлдвэрлэл эрхэлж буй аж ахуйн нэгжийн үйл ажиллагаа өнөө маргаашийг аргацаасан, эрсдэлтэй байдалд байгааг харуулж байгаа юм. Иймээс ХААн гаралтай хүнсний бүтээгдэхүүн үйлдвэрлэлийн анхан шатны бүх нэгжид үйлдвэрлэлийн үйл ажиллагааны зөв дадал, технологи тогтоож мөрдсөнөөр хэрэглэгчдэд очих бүтээгдэхүүний аюулгүй байдал, чанар дээшлэхийн зэрэгцээ АА-н нэгжийн үйл ажиллагаа эрсдэлээс хамгаалагдах юм.

Царгас нь тэжээллэг чанар өндөртэй, өвсний ургац сайтай, ган, хүйтэнд тэсвэртэй уургийн агууламжаараа хамгийн өндөр малын тэжээлийн олон наст ургамал. Ургамлын ургалтанд нөлөөлдөг абиотик стрессийн нэг нь хөрсний давсжилт юм. Дэлхийн дулаарал нэмэгдэж байгаатай холбоотойгоор усалгаатай нөхцөлд царгас тариалах шаардлагатай болж байгаа нь хөрсний давсжилтыг ихэсгэсээр байна. Монгол орны нөхцөлд таримлаар ургадаг “Бургалтай” сорт-Medicago varia Marthz, Монгол оронд нутагшсан Өвөрмонголын “Нутаг Бэлчээр -2” сорт - Medicago varia Martyn, “Бургалтай” сортын эцэг, эх болох ОХУ-ын хөх царгас - Medicago sativa, нутгийн шар царгас - Medicago falcata-ийн давсанд тэсвэрлэх чадварыг лабораторийн нөхцөлд харьцуулан судлав. Давсны ялгаатай (0, 50, 100 ба 200 мМ) концентрацтай бүхий уусмалаар үйлчлүүлсэн үрийн соёололтыг 8 дахь хоногт, морфологи, физиологийн зарим үзүүлэлтүүдийг 14 дэхь хоногт хэмжив. Судалгааны дүнгээр үрийн соёололт, хуурай жингийн индекс, хлорофиллын агууламж, үндэсний урт, жингээрээ M.sativa болон М.falcata нь давсанд тэсвэртэй болохыг харуулав. Харин ус шингээх эрчим, ишний урт, жингээрээ Нутаг Бэлчээр-2 сорт нь бусад царгасаас илүү байна. Туршилтын дүнгээс үзэхэд Бургалтай сорт нь давсанд тэсвэргүй болохыг тогтоов.

Монгол хэлний өгүүлбэрийн бүтцийн судалгааг хийхийн тулд үгийн дотор илэрч байгаа хэлзүйн утгыг тодорхойлох шаардлагатай болдог. Мөн хэлзүйн хувиллаар хувилсан үг бүрийг үгийн санд хадгалах нь залгамал бүтэцтэй монгол хэлэнд тохирохгүй байв. Ийм учир үгийг бүтцээр задлахдаа үгийн сангийн болон хэлзүйн утгыг нь ялгах зорилго тавилаа. Гэтэл орчин цагийн кирилл бичигт зөв бичгийн дүрмийн алдаатай бичвэр их тохиолдож байв. Иймээс зөв бичгийн дүрмийн алдаатай бичвэрээс үгийн сангийн болон хэлзүйн утгыг нь ялгах шаардлага тулгарсан. Ийм учираас нөхцөлийн залгагдах шинжээр үгийг бүтцээр задлах аргыг шинээр зохиолоо. Энэ аргаар зөв бичгийн дүрмийн алдаатай бичигдсэн үгээс үгийн сангийн болон хэлзүйн утгыг ялгаж чадаж байна. Мөн ижил хэлбэртэй үгсийг нөхцөлийн залгагдах шинжээр нь нэр, үйл эсэхийг ялаж байв. Гэтэл нэр үг дотроо ялгаатай хувилж үгийн утга ялгадаг. Үүнийг ялгахгүй байсан. Иймээс морфотактикийг үгийн салаа утгыг ялгах, зөв бичгийн дүрмийн алдааг засварлахад ашиглав. Хувилсан үгээс үгийн салаа утга ялгах нь чухал ач холбогдолтой. Учир нь кирил бичигт үг хувилсан хэлбэрээрээ тохиолдох нь элбэг (68%) байдаг. Мөн зөв бичгийн дүрмийн алдааг дүрэм ашиглан автоматаар засварлах ажил хараахан хийгдээгүй шинэ ажил юм. Кирил бичгийн өнөөгийн цахим боловсруулалтаас харахад монгол хэлний өөрийнх нь онцлогт суурилсан үг хувилах загвар боловсруулах шаардлагатай байв. Иймээс бид кирил бичгийн хэлзүйн дүрэм, авиазүй зарчим, монгол хүний сэтгэхүйн онцлог зэргийг үг хувилах загвартаа тусгахыг хичээлээ.

This study evaluated the antimutagenic and cytotoxic effects of some plants growing in Mongolia and plants were selected on the basis of their traditional use in various diseases. Over the past years numbers of cancer incidences are increasing in Mongolia. There are accounted several reasons, in particular the use of less guaranteed imported food, heavy air pollution, environmental contamination and low life quality of the population. Therefore, we attempted to search antimutagenic activity among plants from the Mongolian flora and possibility of their use for preventing and treating cancer cases. The study might promote the way to fight with cancer, if we can find antimutagenic active compounds from natural crude drugs, including medicinal plants.We have examined the antimutagenic and cytotoxic effects of 20 samples, which prepared from different parts of 10 plants species. The antimutagenic and cytotoxic tests were performed as described by Ames. The bacteria used in the test are a strain of Salmonella typhimurium TA1537, and using 9-aminoacridine as direct mutagen.From the 20 plant extracts studied, extracts of Achnatherum splendens Trin. (aerial parts), Cynoglossum divaricatum Steph. (roots, stems), Juniperus sibirica Burgsd. (leaf, stem) strongly inhibited mutagenicity of 9-aminoacridine and their inhibition activity was 49.7%, 41.5%, 61.5%, 40% and 43% respectively. All plant extracts have not any cytotoxic effect on Salmonella typhimurium TA1537.From the high active plants Juniperus sibirica Burgsd. (aerial parts) which was selected for further detailed study 3 pure active compounds as JS-1, JS-2 and JS-3 were isolated. The compound JS-3 showed the high (55%) antimutagenic activity and its molecular structure was determined as cetyl alcohol or hexadecanol-1 according to its physical and chemical characteristics as well as 1H-NMR and 13C-NMR spectroscopy analysis.We have revealed that the availability of plants possessing antimutagenic activity among the Mongolian flora. Consequently, it is needed further detailed study of active plants, isolation and identification of active pure compounds, as well as possible application of the active plant products in the medicinal practice.

Authors: M.M. Yousaf  , Umer Nasar
Published: June 2017

Urease was immobilized on commercial cotton and commercial cotton activated with glutaraldehyde. The kinetic of urea hydrolysis by free and immobilized urease was studied as a function of pH, temperature and time of hydrolysis. High concentration of ammonia was released at pH 10.0 for free enzyme (0.097 mg/mL) and urease immobilized on cotton (0.092 mg/mL) and pH 4.0 for enzyme, immobilized on activated commercial cotton (0.083 mg/mL). High concentration of ammonia was released at 30 °C for free enzyme (0.006 mg/mL), 25 °C for urease immobilized on cotton (0.043 mg/mL) and urease immobilized on cotton activated with glutaraldehyde (0.015 mg/mL). High concentration of ammonia was released after 10 minutes for free enzyme (0.0016 mg/mL), 60 minutes for inactivated (0.043 mg/mL) and for activated cotton (0.015 mg/ml). The result show that immobilized urease is less effective than the free enzyme and is more active in acid medium than the basic medium.
