Authors: Rahman Taufik , Rochintaniawati Diana
Published: September 2016

Questioning plays an important role in teaching learning process. The effect of prompting question and non-prompting question in biology teaching learning process on increasing student’s understanding and student’s retention was evaluated in this study.  The method used in the study was experimental involving students in control group who used student experiment and non-experiment worksheet without prompting question and students in experimental group who used student experiment and non-experiment worksheet with prompting question. The study was carried out in 4 concepts, i.e. the environment sustainability, water pollution, environment study, as well as sight organ in Invertebrate. To evaluate the different effect of student worksheet with prompting question and student worksheet without prompting question on increasing student’s understanding and retention posttest 1 and post-test 2 was given to the two groups in time interval of 2,3 and 4 weeks. From the result of the two tests the retention was measured. The study revealed that in the concept of Environment sustainability, environmental study and water pollution the use of student worksheet with prompting question as well as without prompting question was effectively increased student’s understanding to the concept, and the increasing of student’s understanding to the concept between control and experiment group was equally the same. Meanwhile in the concept of the organ sight in invertebrate the use of experiment student worksheet with prompting question more effectively increased student’s understanding to the concept than the use of experiment student worksheet without prompting question. Student in the experiment group performed better retention on the concept than student in control group.

An Experiment on the effect of different nitrogen source in Murashige and Skoog media (MS, 1962) on senesionin production of compact globular structure of Crotalaria anagyroides has been performed. CGS culture was obtained from callus culture on liquid MS media with 5.10-5 M NAA and 10-6 M kinetin. The CGS was transfered into media with different nitrogen source: MS A (amonium+nitrat), MS B (nitrat) and MS C (amonium). Qualitatif data showed that senesionin could be detected in the CGS exstract by appearence of spot (Rf=0,78). The quantitative data showed that MS C was the best media to produce 4623 g/DW senesionin on 30th day.Key Word : Crotalaria angyroides, Nitrogen Source, Senesionin, Senesionin Production.

Caracterización de las construcciones pasivas con complemento agente explícito
Authors: Funes María Soledad
Published: September 2016

En el marco teórico del Enfoque Cognitivo-Prototípico, el presente trabajo propone el estudio comparativo de las construcciones pasivas con complemento agente (CAg) explícito introducido por las preposiciones por y de en discurso auténtico. Se sostiene que en el caso de la preposición de, el atributo más relevante para su aparición en contexto de CAg es el tipo de predicación: de ocurre con predicaciones estáticas, con pacientes poco afectados, más allá del grado de determinación del agente y paciente, y de si son [+humanos] o [-humanos]. La preposición por, en contraste, ocurre en predicaciones dinámicas, con pacientes altamente afectados. El hecho de que la preposición de sea elegida por el hablante en las predicaciones estáticas se debe al significado básico de posesión que tiene de (Funes, 2015). Para comprobar las hipótesis, se analizarán ejemplos del corpus oral PRESEEA-Buenos Aires (Proyecto para el Estudio Sociolingüístico del Español de España y de América), de los años 2010-2011 y de un corpus escrito de notas periodísticas del año 2014.
De haberlo sabido...: condicionales con de y para
Authors: Marcovecchio Ana María , Pacagnini Ana María Judith , Kaller Andrés
Published: September 2016

En el español, son varias las preposiciones que combinadas con infinitivo o con cláusulas con que, conforman prótasis condicionales. Así, se ha destacado que para las lenguas románicas, por ejemplo, es común que a permita introducir condicionantes; aunque en el caso del español, es el infinitivo preposicional con de la forma más difundida en la actualidad para la expresión de la condicionalidad. Con para, con y sin pueden también constituirse prótasis condicionales; no obstante, estos nexos devenidos en conjunciones más o menos gramaticalizadas no son intercambiables en todos los casos. De hecho, con respecto a de y para, advertimos restricciones de conmutación de una por otra: De (/*Para) llegar temprano, podremos realizar todo lo que tenemos previsto, Para (/*De) haber escrito una carta tan linda, debes de ser una niña muy inteligente. Asimismo, si se admite sustitución, se produce una interpretación distinta: Para ser reelegido en un lugar como este (=si querés ser reelegido), tenés que gobernar bien /De ser reelegido en un lugar como este (=si sos / fueras reelegido en un lugar como este), tenés que gobernar bien. Efectivamente, el contraste semántico en estos dos últimos ejemplos se vincula con la interpretación temporal del infinitivo en la prótasis: con para, de posterioridad al condicionado, y con de, de anterioridad.

Published: September 2016

ResumenEn este trabajo se desarrolla un modelo de gestión para las empresas inmobiliarias, que permite analizar su desempeño periodo a periodo bajo un esquema de mejora continua, el cual puede ser aplicado por las empresas independientemente de su tamaño. El modelo en cuestión ha sido generado con los juicios de valor de especialistas en gestión inmobiliaria de empresas chilenas, a través del uso de la metodología de análisis jerárquico de proyectos. El método de Análisis Jerárquico de Proyectos (AHP), utilizado para determinar las prioridades de cada elemento de evaluación, ha permitido establecer valores precisos, consistentes y consecuentes de medición del desempeño de la gestión en el negocio inmobiliario. El proceso de desglose de los objetivos en criterios agrupados bajo un esquema estructurado con 26 variables, posibilita disponer de un cuadro de mando integrado, que devela los aspectos más significativos para el negocio inmobiliario, de los cuales 9 explican cerca del 70% del índice de gestión de desempeño. Destacando una preocupación equilibrada entre rentabilidad, crecimiento y estabilidad, lo cual muestra que las empresas tienen como objetivo su permanencia en el mercado y no sólo rentabilizar una inversión. De igual forma el modelo muestra una significativa preocupación por los clientes externos de la empresa y también al cliente interno, ya que, manteniendo satisfecha a las personas, se logra una mayor productividad y el logro de los objetivos de las empresas.AbstractThe development of this work is a management model of real states companies that allows analyze its performance in a time control period under a continuous improvement scheme, this model could be applied in all types of companies regardless of its size. This management model has been generated with value judgment of Chilean specialist in real states companies, through a project hierarchical analyze method. The Project Hierarchical Analyze method (AHP), used to evaluate the priority of each evaluation element, has allowed to establish precise, consistent and consequence values for measuring the development of real states management business. The process of target breakdown into grouped criteria under a structured scheme of 26 variables, allows to construct an integrated control panel, showing the most relevant indicators for the real states business, of which 9 can explain near 70% of the key performance indicators. Highlighting a balanced concern among profitability, growth and stability, which shows that companies aim their stay in the market and not just a return on investment . Similarly the model shows a significant concern for the external customers of the company and also the internal customer, since keeping people happy, higher productivity and achieving the objectives of the companies is achieved.

Authors: Zhang Yaxia , Ilaslan Hakan , Krishnaney Ajit A. , Bauer Thomas W.
Published: September 2016

Case:

Denosumab, an inhibitor of RANKL (receptor activator of nuclear factor κ-B ligand), was recently introduced for the treatment of giant-cell tumor of bone (GCTB). We describe the clinical, radiographic, and histological features of a GCTB of the spine in a 24-year-old woman that progressed after neoadjuvant treatment with denosumab. Disappearance of the multinuclear osteoclastic giant cells was accompanied by newly formed woven bone, which was deposited in interconnected strands with a prominent fibrovascular stroma that was histologically and radiographically similar to that of an osteoblastoma.

Conclusion:

Pathologists, radiologists, and surgeons should be aware of this post-treatment transformation to avoid misdiagnosis.

Authors: Massardi Wellington De Oliveira , Abrantes Luiz Antônio
Published: September 2016

A presente pesquisa buscou demonstrar o nível de dependência dos municípios mineiros em relação ao Fundo de Participação dos Municípios (FPM). Para alcançar esse objetivo foi demonstrada a representatividade do Fundo de Participação dos Municípios na estrutura de financiamento dos municípios, mensurado por meio da divisão entre a receita do FPM e a receita corrente municipal. Verificou-se que a grande maioria dos municípios possui nível de dependência superior a 50%, ou seja, os recursos do FPM representam a principal fonte de financiamento municipal, com destaque para os municípios com população inferior a 20.000 habitantes. Quanto à localização geográfica, verificou-se que há uma concentração maior de municípios que possuem alta dependência do FPM nas mesorregiões da Zona da Mata e Vale do Rio Doce, sendo que nesses municípios a média populacional é de 3.202 habitantes, dessa forma, conclui-se que a dependência do FPM está diretamente relacionada ao tamanho do município.
O voluntariado eventual em competições esportivas
Authors: Lemos Samuel Luz , Almeida Neto Francisco Sérgio , Cavalcante Carlos Eduardo
Published: September 2016

Sob a meta de estudar o fenômeno do voluntariado, aplicado ao contexto de grandes eventos esportivos, este estudo partiu do modelo teórico proposto por Bradford, utilizado aqui como técnica de pesquisa e análise. Para tanto, buscou-se no Portal de Periódicos da CAPES artigos publicados entre os anos de 1993 e 2012, que resultou em 237 trabalhos, dos quais 18 deles discutiam o tema, distribuídos em 14 periódicos. Após as análises, ficou claro que as publicações específicas do assunto são escassas, sem muitas discussões aprofundadas e sem uma literatura base, o que, provavelmente, motivou a não obediência plena da Lei de Bradford; por outro lado, confirmou-se a hipótese de Guedes (2005) de que a pesquisa em umassunto gera mais estudos e publicações nele, pois, nos 20 anos investigados, apenas a partir de 2007 há uma sequência de trabalhos. Afora isto, identificou-se que as motivações e conclusões dos estudos não são harmônicas.

Mobile technology has begun to transform the way young retail consumers shop, allowing them more intermediate control over purchasing process. With competition accelerating in retail industry, mobile devices have been used widely in delivering value-added services. Hence, mobile commerce is likely to make a strong influence on business activities, consumer behavior, as well as national and global markets. The purpose of this paper is to identify key factors influencing customer satisfaction and loyalty in mobile commerce by empirically-based research questionnaire. Based on previous literature, the paper builds sets of customer satisfaction and loyalty constructs for mobile commerce.  Significant constructs and their relationships are examined by m-commerce satisfaction model employing structural equation model. Research findings indicate that all constructs significantly affect Smartphone customers’ satisfaction, except for the price. Furthermore, satisfaction has moderately strong influence on Smartphone customer’ loyalty. The implication of this research to researchers and practitioners is discussed.
Improving People's Lives: What You Do is Important
Authors: Meehan Nathan
Published: September 2016

President's column

Each SPE president chooses a tagline for his or her monthly column, often referencing an underlying theme. Improving people’s lives is what we do as petroleum engineers, so it is an important theme for us. Oil and natural gas production raises the standard of living of people throughout the world. In the coming months, I will use this column to talk about some of the challenges and opportunities we face and some of the great things happening with SPE members around the world.

Why did you choose to become a petroleum engineer? For decades, I have posed this question to students and young professionals and have received many interesting responses. All too often, the responses include, “I read that petroleum engineers have high starting salaries.” There is nothing wrong with making money; highly skilled professionals who have invested a great deal of time and effort in their education and work hard should be well paid. That being said, choosing petroleum engineering or going to work in the upstream oil and gas industry with an engineering, Earth science, or other technical degree should not be based solely on how much money one can make.

Imagine that a high school senior who respects and trusts you comes to you seeking advice. Her first question is, “What are the most important things I should look for in deciding on a career?” Quickly, name three things. Possible answers include enjoyable work, career/life balance, stress and hours required “on the job,” financial security, the opportunity to make a lot of money, location, opportunities for travel, advancement or continuing education, types of personal interactions, reputation of the company/industry you work for, or satisfaction that you are doing something important.

As our prospective college student learns these things, she will have a better idea about satisfying career choices. A friend of mine chose a high-stress Wall Street job that afforded him almost no personal life but a chance to make more money than most of his peers. His college roommate took a 40-hour-a-week job in his hometown and has no expectations of getting rich.

The oil and gas industry is a great place to work for technical professionals. It is exciting, challenging, and rewarding. While a few achieve great wealth, hardworking engineers and Earth scientists do not have to “strike oil” to do well in their careers. There are many types of jobs in our industry with varying levels of opportunities and risks. But what about the reputation of our industry? Are we doing something important?

The reputation of the oil and gas extractive industry is undeservedly low, typically among the lowest in any survey. Only ExxonMobil appears on the 2015 Fortune list of the top 50 most admired companies. Our industry’s reputation is unfairly tarnished in part by rare, high visibility oil spills and by a lack of understanding of the importance of energy in our society. We really do something very important for the world. Our role in the world is often unappreciated.

Published: September 2016

Se analizó el tratamiento ideal usando baños termotratados para la separación de cal de los residuos de descarne, del proceso de curtición semiartesanal desarrollado en Sampués, Departamento de Sucre (Colombia). Para su desarrollo se seleccionó una muestra de carnaza representativa, homogénea y con menos tiempo de almacenamiento. Dicha muestra se redujo al tamaño de 1 cm2 y se conservó refrigerada para posteriormente realizar los análisis de grasa, pH y presencia de cal. Los baños termotratados de desencalado se realizaron a tres temperaturas diferentes (26, 30 y 35 ºC). Se utilizó como agente desencalante el acido sulfúrico en tres concentraciones (3, 2 y 1 N). Además se usó un sistema de agitación simulando el bombo en proceso industrial. Se llevaron a cabo nueve pruebas con tres repeticiones para mayor confiabilidad de los datos, en donde se determinó la correlación existente entre las variables independientes, temperatura y concentración, sobre la cal impregnada y los resultados de grasa en cada una de las muestras en un tiempo de 4 y 8 h.
Submarine groundwater discharge and alkaline earth element dynamics in a deltaic coastal setting
Authors: Coleman Daniel J. , Kolker Alexander S. , Johannesson Karen H.
Published: September 2016

Submarine groundwater discharge is a process that is often considered negligible in deltaic systems given their low gradient and fine-grained sediment. However, hydrologic budgets and radon surveys indicate that it may be a significant component of the Mississippi River Delta system. To more concretely indicate groundwater's contribution to the local environment, we conducted an analysis of estuarine water chemistry. We focused on the mid-weight alkaline earth metals, which differ significantly in the system's three end-members: river, ocean, and groundwater. We found an anomaly of barium in the estuaries, which could not be completely explained by desorption. Through the construction of a three-end-member mixing model, groundwater was estimated to comprise 14–28% of Terrebonne and Barataria Bay estuarine water, which corresponds to a combined discharge of 160–480 m3/s. This groundwater discharge helps explain the hydrologic budget of the system, and could influence the chemistry of these large deltaic estuaries.

Authors: Bi Qiang , Xue Juanqin , Guo Yingjuan , Li Guoping , Cui Haibin
Published: September 2016

The recycling of copper and nickel from metallurgical wastewater using emulsion liquid membrane (ELM) was studied. P507 (2-ethylhexyl phosphonic acid-2-ethylhexyl ester) and TBP (tributyl phosphate) were used as carriers for the extraction of copper and nickel by ELMs, respectively. The influence of four emulsion composition variables, namely, the internal phase volume fraction (ϕ), surfactant concentration (Wsurf), internal phase stripping acid concentration (Cio) and the carrier concentration (Cc), and the process variable treat ratio on the extraction efficiencies of copper or nickel were studied. Under the optimum conditions, 98% copper and nickel were recycled by using ELM. The results indicated that ELM extraction is a promising industrial application technology to retrieve valuable metals in low concentration metallurgical wastewater.
OS SENTIDOS DA GESTUALIDADE: TRANSPOSIÇÃO E REPRESENTAÇÃO GESTUAL
Authors: De Barros Diana Luz Pessoa
Published: September 2016

Neste artigo são apresentadas, na perspectiva da semiótica discursiva francesa, algumas direções teóricas para o estudo dos sentidos da gestualidade na sociedade contemporânea, em quatro circunstâncias: a gestualidade poética da dança; a gestualidade nos tratamentos de fisioterapia; a passagem do gesto ao “signo” na língua de sinais; a gestualidade representada na pintura, na fotografia, na publicidade, etc. O ponto de partida deste estudo é o texto de Greimas Conditions d’une sémiotique du monde naturel (1970, p.62). Nesse quadro teórico, tratamos de duas questões: das operações de transposição gestual – semantização, dessemantização, mimetização, simbolização, passagem do gesto ao signo, nas línguas de sinais; da representação da gestualidade, em particular na publicidade de bancos, e dos efeitos de sentidos por ela produzidos nesses discursos publicitários.

Treatment of infected and septic wounds remains one of the most important problems of pediatric surgery. According to the authors, the wound process monitoring affects the treatment outcome not less than operative technique.The objective of the research was to examine the dynamics of microcirculation of the infected and septic wounds in children.Materials and methods. The analysis of the study of infected and septic wounds microcirculation in 178 children was performed. Blood flow laser analyzer (“LAKК-02” RPE “Lazma”, Russia) was used to study the blood flow in the wound area. Monitoring of wound healing process dynamics was conducted by studying the wound healing cytogram.Results. On the first day the average parameter of microcirculation was markedly increased in the area of wound edges in comparison with the contralateral area. The subsequent study of a blood flow during 5 days showed that average value of microcirculation parameter in the wound area decreased by more than 2 times in comparison with the figures on the first day. Microcirculation parameters of in the wound area further decreased.Conclusions. Dynamics of microcirculation changes in wound healing process significantly corresponds to cytogram of impression smears obtained from infected and septic wounds in children. Laser Doppler flowmetry is an effective method microcirculation control and minimally invasive diagnostic method of wound healing process.

Published: September 2016

Tradicionalmente as famílias da região Centro-Serra do estado do Rio Grande do Sul criam suínos (Sus scrofa domesticus) como fonte de subsistência, porém nesta região estão inseridas apenas algumas pequenas agroindústrias de abate e processamento de carne suína. Uma destas agroindústrias possui certificação para comercialização apenas em território municipal, no entanto devido ao interesse na ampliação do negócio para o território estadual, é necessária a construção de uma nova planta industrial. Deste modo, com o objetivo de analisar a viabilidade econômica da implantação de uma nova unidade industrial nesta região, foi utilizado um questionário de campo e pesquisas de mercado, além de análises do orçamento de infraestrutura para o levantamento dos custos de implantação de uma nova unidade.Os dados obtidos foram lançados em um fluxo de caixa com prazo de dez anos na intenção de avaliar a viabilidade econômica. Foram utilizados os indicadores Taxa Interna de Retorno – TIR, Valor Presente Líquido – VPL, e o tempo de retorno do capital investido – Payback, como forma de analisar o investimento. A análise econômica resultou em uma TIR de 22%, VPL de R$ 271.099,67 para uma taxa de atratividade de 10 %, e Payback de três anos e onze meses. Com esses resultados positivos, do ponto de vista econômico, a implantação de uma nova unidade de abate e processamento de suínos para a referida região apresenta-se como um investimento altamente atrativo.
Critérios utilizados por universidades públicas para o abandono de patentes e de pedidos de patentes não licenciados
Authors: Brito Eduardo Vieira de , Fausto Daiane Aparecida
Published: September 2016

As universidades têm se atentado cada vez mais à importância da proteção e gestão de suas propriedades intelectuais. Embora tais instituições se empenhem em proteger soluções com grande potencial mercadológico, a maioria dos pedidos de patente não é licenciada e gera um significativo custo de manutenção e gestão. Neste contexto, objetivou-se analisar comparativamente os critérios utilizados por universidades públicas para o abandono de patentes e pedidos de patentes não licenciados com a finalidade de conservarem em seus portfólios apenas as invenções com alto potencial de licenciamento e utilizarem de maneira mais eficiente os recursos públicos disponíveis. Nas universidades brasileiras não foi constatada metodologia consolidada neste quesito. Nas avaliações continuadas realizadas pelas instituições do exterior observou-se a participação ativa dos inventores e a autonomia do departamento responsável pela gestão das propriedades intelectuais para decidir pela manutenção ou abandono da proteção.

Published: September 2016

O levantamento de preços de insumos agrícolas – principais produtos utilizados na produção de cana de açúcar - e valor de mão de obra, realizado pelo Programa de Educação Continuada em Economia e Gestão de Empresas – PECEGE, para a safra 2014/2015, evidenciou a importância dos itens analisados na variação dos custos de fornecedores de cana. Apesar da classe de corretivos ter sido a que apresentou maior variação de preços (160%), foi a classe de fertilizantes que gerou maior impacto nos custos com insumos (R$0,30/ton). Já para o item mão de obra, apesar da variação positiva nos preços ocasionada pelo reajuste salarial, a variação nos custos de produção foi negativa, indicando possível redução de quadro de funcionários em detrimento do aumento de mecanização da lavoura. Para a safra 2015/2016, há expectativa de que a queda dos preços internacionais dos derivados de petróleo amenize os impactos da valorização cambial, a qual tem grande influência nos preços dos insumos, principalmente sobre a classe de fertilizantes.

This research assesses the suitability of the Six-sigma program for R&D in FMCG companies. The study also includes an analysis of its potential advantages and challenges for this business area. This was performed through data acquisition using a web-based survey targeting large scale multinational companies. Results showed that most R&D personnel within FMCG companies see Six-sigma as a positive methodology for their sector. Roughly 80% of the participants selected time saving and better knowledge allocation as the main advantages of the Six-sigma system. Almost 90% of the survey contributors believe that the series of potential benefits could lead to important scientific breakthroughs. A financial challenge is expected with the implementation and it was said to be the main concern of R&D personnel, especially from those with managerial backgrounds. Cultural changes and scientific obstacles were not reported as imminent threats to the new system. In light of the above, Six-sigma was found to be suitable for R&D in FMCG companies requiring only a few modifications in its standards and a well-defined strategic implementation plan.

Desde novembro de 2014 é obrigatória a adição de 7% de biodiesel ao diesel. A venda do produto é regulamentada pela Agência Nacional do Petróleo, Gás Natural e Biocombustíveis [ANP] e realizada bimestralmente através de leilões públicos. O combustível pode ser produzido a partir de diversos insumos, porém, o óleo de soja tem sido o principal utilizado até o momento. O presente trabalho teve como objetivo analisar a relação entre o preço do biodiesel com o preço de seu principal insumo e a oferta de biodiesel nos leilões. Foi analisado o preço do biodiesel nos leilões 28 ao 39, referentes ao primeiro bimestre de 2013 até o último bimestre de 2014. Para avaliar a influência das variáveis mencionadas sobre o preço do biodiesel utilizou a regressão linear simples e correlação de Pearson. O preço do óleo de soja mostrou ser responsável por 65,41% da variação do preço do biodiesel enquanto o volume ofertado foi responsável por 33,37%. A correlação do preço do biodiesel com o preço do óleo de soja foi de 0,81 e com o volume ofertado no certame foi de -0,58. O preço do óleo de soja corresponde a cerca de 80% dos custos de produção do biodiesel, portanto isto pode explicar a maior correlação entre as variáveis.

Os animais domésticos estão assumindo grande importância no convívio com as pessoas, sendo cada vez mais considerados como membros da família. Com o crescente número desses animais nos lares brasileiros se faz necessário profissionais e clínicas especializadas para atender a demanda de cuidados e bem estar animal. Diante destes fatos, o objetivo do trabalho foi levantar os custos e analisar a viabilidade econômica da instalação de uma clínica veterinária completa, nos moldes de um hospital veterinário, que realize desde procedimentos básicos até os mais complexos em um mesmo local, na cidade de São João da Boa Vista, São Paulo. Para essa análise realizou-se o levantamento dos investimentos necessários para a instalação da clínica, bem como os custos fixos e variáveis, e receitas obtidas com os atendimentos. Elaborou-se um fluxo de caixa, considerando período de 5 anos de vida útil do projeto e realizou-se a análise de viabilidade econômica utilizando-se os indicadores Valor Presente Líquido [VPL], Taxa Interna de Retorno [TIR], payback simples e descontado, além de análise de sensibilidade para avaliar o efeito da variação do investimento, receita e taxa de juros sobre o VPL. Pelos resultados verificou-se que o projeto de instalação da clínica veterinária é economicamente viável, apresentando VPL de R$ 152.049,33, TIR de 12,68%, payback simples de 4,13 e payback descontado de 4,38 anos. O VPL mostrou-se bastante sensível à variação da receita, seguido pelo investimento, cujo aumento interferiu negativamente no VPL. Menor sensibilidade foi observada em relação à variação da taxa de juros.

The article deals with the problems of studying the process of dispersing liquid fuel and water-fuel emulsions, in particular the characteristics of the dispersed spray in high-potential electrostatic fields. The paper deals with the development of a research method for disperse characteristics of liquid fuels, in particular, the changes in the diameter of the spray particles of liquid fuels and water-fuel emulsions based on them, depending on the intensity of high-grade electrostatic field. These studies are relevant in the creation of new devices based on new dispersion, which are not currently used for fuel atomization and combustion devices, in particular based on the electrostatic dispersion. The currently available methods for assessing dispersion are based on the evaluation of the particle diameter, which are formed by dispersing (particle breakage) of the liquid fuel. The views expressed in the course of the study suggest that the dependence of the particle diameter from the electrostatic field can be estimated not only in case of the destruction of the particles (dispersion), but also in case of the formation (growth) of drops during the expiration of the capillary. In order to confirm the provisions the authors developed the installation and technique to study the changes in the dispersion in dependence with the voltage value of high potential electrostatic field. The results of experimental studies are presented and experimental graphics are built for F5 bunker fuel and water-oil emulsions with different concentrations based on it. On the basis of the experimental data processed by correlation analysis method the authors obtained the mathematical model of diameter changes of the particles under the influence of an electrostatic field, which corresponds to the theory of electrostatic dispersion. The developed technique greatly simplifies the determination of the disperse characteristics of liquid fuel in case of electro-static dispersion.

Different aerated mortars are used for pargeting of walls made of aerated concrete. Though the regulatory documents don’t specify the dependence of plaster density from the density grade of gas-concrete blocks. In case of facing of gas-concrete blocks with the grade D500 using plaster mortars with the density 1400…1600 km/m3 there occurs a dismatch in the values of thermal insulation and vapor permeability of the plaster and base. The authors suggest using dry mortars for finishing of gas-concrete block of the grades D500 и D600, which allow obtaining facing thermal insulating coatings. The efficiency of using four different high-porous additives in the lime dry mortar was compared. They were: hollow glass microspheres, aluminosilicate ash microspheres, expanded vermiculite sand, expanded pearlitic sand. The high efficiency of hollow glass microspheres in heat insulating finishing mortars compared to other fillers is proved.

Aiming to demystify intramuscular injection into the lateral femoral region, which, according to some authors is a technique that can lead to injury of the sciatic nerve, held the anatomical study of the femoral region. Thus, we used ten mongrel dogs of different sizes, age and sex, fixed in formaldehyde solution 10%. We identified the visible and palpable bony projections of gluteal, femoral and crural regions. Dissection of these regions, identifying the muscles, vessels and nerves of the lateral surface. With a syringe containing dye was injected a small quantities in various parts of the lateral femoral region observing the proximity of the points marked with sciatic nerve. It was observed that the sciatic nerve protruded deep into the center of the distance between the imaginary lines drawn from the greater trochanter of the femur to the lateral condyle of the tibia and the ischial tuberosity to the lateral condyle of the tibia. It was concluded that intramuscular injection in the lateral femoral region is safe, since respect that line, and that the most suitable intramuscular injection would beat the center of an imaginary line drawn from the ischial tuberosity to the lateral condyle of the tibia, without risk of injury sciatic nerve.

Artificial Insemination (AI) in sheep is a reproductive biotech that, combined with other biotechnologies such as induction / synchronization of estrus and ovulation and semen technology, can add value to the livestock by allowing the use of sires of high genetic pattern, using females outside the breeding season and standardize lots of products generated. This work aims to present the various types of AI, based on technical and technological level of the consequent form of semen deposition: vaginal, cervical or intrauterine, whether laparoscopic or transcervical route. Comparative results of conception, pregnancy, fertility and prolificacy, traits and influences, such as cervical anatomic status of ewes, types of semen and sperm concentrations are discussed. We also include some physiopathological implications arising from transcervical techniques such as inflammatory / infectious reactions in the reproductive tract, or laparoscopic techniques, like regurgitation of rumen contents and respiratory acidosis by pneumoperitoneum. Thus, we seek the understanding that, despite the demand for scientific advances in AI techniques, one cannot ignore the need to preserve the welfare of these animals.
