POTENSI PENURUNAN EMISI GAS RUMAH KACA PADA PENGELOLAAN KOTORAN HEWAN SAPI MELALUI PEMBERIAN PAKAN TAMBAHAN
Authors: Pramono Ali 
Published: August 2018

On the integration of crop-livestock systems, waste biomass is used as feed for livestock. Low feed quality may increase emissions of greenhouse gases (GHG). Therefore, to reduce emissions from livestock sector is to improve the quality of animal feed. The purpose of this study was to obtain additional information about the effect of feeding (silage, hay ammoniation and UMMB) against greenhouse gas emissions from cattle manure in crop-livestock integration system. The experiment was conducted at the experimental field of Indonesia Agricultural Environment Research Institute (IAERI/Balingtan), Pati in May-July 2014. The method used to measure the GHG emissions is close chamber method, with an interval of 10 minutes.
Samples of CO2, CH4 and N2O were analyzed using gas chromatography. The results showed that treatment of conventional feeding + feed supplement could reduce GHG emissions as 19 % compared to a conventional feeding. GHG emissions from animal manure fed conventional feed of 9.13 kg/head/year, whereas with
conventional feed + additional feed of 7.39 kg/head/year.

Published: August 2018

Este artigo apresenta uma pesquisa, ainda em andamento, que consiste em fazer um estudo da obra Arithmetica Infinitorum de John Wallis (1616-1703), publicada em 1655, na qual analisamos a aplicação da abordagem utilizada pelo autor na perspectiva de fazer uma conexão com o ensino nos dias de hoje, além de investigar sua efetividade em sala de aula para a aprendizagem de conceitos relacionados ao Cálculo Diferencial e Integral, procurando em sua metodologia elementos que possam contribuir para uma forma de ensino do Cálculo baseado mais na descoberta do que no rigor característico dessa disciplina. Desta forma procuramos compreender a forma inovadora de Wallis tratar algumas questões relacionadas ao Cálculo Diferencial e Integral, investigar como é realizada a abordagem de alguns de seus conceitos e relacioná-los com o ensino atual. Esse trabalho se fundamenta essencialmente nos estudos realizados nos últimos anos por pesquisadores interessados na área da História da Matemática que defendem o uso da História da Matemática como recurso a ser incorporado na sala de aula além de levar em consideração o que sugerem alguns documentos oficiais brasileiros em relação ao ensino da Matemática (PCN, DCN, OCM, etc.). Os resultados apurados apontam que esta obra foi de grande influência nas descobertas posteriores sobre os principais conceitos do Cálculo Diferencial e Integral. No nosso caso específico, até então, verificamos apenas a presença de comentários a respeito da obra Arithmetica Infinitorum e de seu autor em dois livros clássicos de História da Matemática e também em um artigo específico sobre este tema. Ao analisar estas obras, percebemos certas características específicas deste autor que podem ser de grande utilidade ao estudar questões relativas ao ensino nos dias atuais. Espera-se que esta pesquisa possa facilitar a compreensão dos conceitos de Cálculo Diferencial e Integral e assim contribuir para o seu ensino e, consequentemente para a sua aprendizagem.

Este trabalho se enquadra no campo da História da Educação Matemática e apresenta uma visão sobre o livro Arithmetica Pratica (1908) de Manoel Evaristo Ferreira, tendo em vista responder aos seguintes questionamentos: Quais as diretrizes educacionais brasileiras no período da publicação do livro? Tais recomendações foram utilizadas pelo autor na elaboração do livro? Há a presença do Método Intuitivo na obra? Tendo em vista esses questionamentos, foi estabelecido como objetivo geral desta pesquisa verificar a presença do Método Intuitivo baseado em Primeira Lição das Coisas de Calkis (1886), no livro Arithmetica Pratica (1908) de Manuel Evaristo Ferreira. Desde modo, realizamos pesquisas relacionadas às obras do século passado, na biblioteca da Sociedade Beneficente e Literária Cinco de Agosto e na Biblioteca Irene Favacho Soeiro, ambas localizadas no município de Vigia – PA, seguimos com pesquisas bibliográficas relacionadas ao contexto histórico do livro Arithmetica Pratica (1908) e posterior análise de documentos sobre o Método Intuitivo defendido por Calkis (1886). Vale ressaltar que não conseguimos, neste trabalho, traçar um perfil biográfico do autor em virtude da escassez de fontes sobre o mesmo. Após as devidas análises no livro Arithmetica Pratica (1908), podemos concluir que seu autor não contemplou o Método Intuitivo defendido por Calkins (1886) em sua elaboração, pois, mesmo utilizando alguns exemplos contextualizados com situações vivenciadas no comércio local, o autor não se enquadrou no que dizem os pressupostos do método na elaboração do livro, tendo em vista que o mesmo apresenta todos seus conceitos de forma pronta e acabada, através de exemplos em que o autor apresenta uma única solução.

Neste artigo, como uma síntese de nossa pesquisa de dissertação de mestrado, na qual nos dedicamos a estudar a vida do matemático italiano Leonardo Fibonacci (1180 - 1250) e de uma de suas obras, o Liber Quadratorum (1225). Objetivamos apresentar uma pequena porção da vida desse matemático brilhante do século XIII e de sua obra. Para tanto, iniciamos descrevendo o ambiente em que Leonardo Fibonacci estava inserido, bem como do Liber Quadratorum. Assim, apresentamos o cenário do décimo terceiro século e o seu renascimento comercial, bem como as transformações que este pré-renascimento ocasionou neste período, que influenciaram Leonardo Fibonacci em suas viagens, o levando a se dedicar ao estudo da álgebra geométrica oriental e dos números indo-arábicos, levando a escrever alguns livros, dentre os quis temos o Liber Quadratorum, que teve como motivação um torneio matemático, sendo convidado pelo rei Frederico II, a quem foi dedicado o livro, apresentamos o contexto e as circunstâncias em que foi escrito este livro e ainda neste trabalho os três primeiros problemas contidos no Liber Quadratorum, assim como, suas explicações e desdobramentos, para que o leitor tenha uma dimensão mais adequada do que se trata o livro. É importante evidenciar que nos baseamos principalmente na tradução de L. E. Sigler (1987) e de forma secundária no trabalho de McClenon (1919). Com o exposto nesse trabalho, percebemos que estes problemas ainda são relevantes e possuidores de potenciais para o ensino e para a aprendizagem de matemática, pois, mostram indícios do estudo das ternas pitagóricas de diversas formas.
Economic and environmental aspects of organization the territory of ecologically clean agricultural land
Authors: Tiutiunnyk Hanna 
Published: August 2018

Introduction. The foundation of the creation of ecologically clean land masses is the economic organization of the territory. The leading component of ecologically safe land use is the need to determine the suitability of land soils for the cultivation of raion crops and the maintenance of maximum soil quality adapted to the quality of crop rotation.
Aim and tasks. In the article the purpose of planning the organization of land mass structures is determined. The task of the internal land management is to formulate a strategy for using land masses that would maximally focus on the actions of land users in optimizing, transforming and using land to the natural conditions of the region.
Research results. Measures to create ecologically pure land masses are carried out directly at agricultural enterprises, therefore, agricultural land use is a prerequisite for them. The organization of agricultural land use envisages for business entities, the establishment of a warehouse, the transformation of lands and conservation of degraded and low productivity land, which at the present stage has become the most effective factor in the environmental optimization of land use. Agroecological organization of the territory includes measures on four systemic properties of agroecosystems: productivity, stability, stability and uniformity. All four properties are interrelated in agroecosystems. Without these links it is impossible to organize the territory in order to create conditions for rational use and protection of land, which is demanded by the agricultural land management system.
Conclusion. In the article the necessity of characterization of qualitative and quantitative characteristics of lands is grounded in order to find out the influence of the creation of the land mass and the appearance of possible dangers. The basic stages of the transition to environmentally safe agriculture and the formation of ecologically clean land masses have been determined. The types of development of the land mass are described: one-time and step-by-step. The complex problems that may be encountered by an enterprise of any ownership type in the transition to the maintenance of ecologically pure agriculture are determined. Creation of ecologically pure massifs of lands and agroecological organization of the territory includes a system of measures for the adaptation of agricultural production, agriculture to the peculiarities of the natural environment, along with the system of levers of state management of rational ecologically safe use of agricultural land. So the necessity of state support and motivation for enterprises planning to switch to the production of ecologically clean products and the formation of ecologically clean land masses has been substantiated.

Glimmering in the Dark: Modeling the Low-mass End of the M•–σ Relation and of the Quasar Luminosity Function
Authors: Pacucci Fabio , Loeb Abraham , Mezcua Mar , Martín-Navarro Ignacio 
Published: August 2018

Abstract
The

relation establishes a connection between central black holes (BHs) and their host spheroids. Supported by observations at

, there is limited data on its validity at lower masses. Employing a semi-analytical model to simulate the combined evolution of BHs and their host galaxies, we predict the observational consequences of assuming a bimodality in the accretion efficiency of BHs, with low-mass BHs (

) accreting inefficiently. We predict a departure from the

relation at a transitional BH mass

, with lower-mass BHs unable to reach the mass dictated by the relation and becoming disconnected from the evolution of the host galaxy. This prediction is an alternative to previous works suggesting a flattening of the relation at

. Furthermore, we predict a deficit of BHs shining at bolometric luminosities

. Joined with a detection bias, this could partly explain the scarce number of intermediate-mass BHs detected. Conversely, we predict an increase in source density at lower bolometric luminosities,

. Because our predictions assume a bimodal population of high-redshift BH seeds, future observations of fainter BHs will be fundamental for constraining the nature of these seeds.
Characteristics of Academic Coaches in an Online RN-to-BSN Program
Authors: Cipher Daisha Jane , Urban Regina Wilder , Mancini Mary E. 
Published: August 2018

Background:
To achieve the growth of RN-to-Bachelor of Science in Nursing (BSN) programs in the face of ongoing faculty shortages, many large online RN-to-BSN programs have embraced the use of academic coaches to assist with course delivery.

Method:
An associational analysis of data collected from academic coaches and their student and faculty evaluators was performed on a sample of academic coaches who were teaching students enrolled in a large online RN-to-BSN program.

Results:
The multilevel data consisted of 94 coaches who taught in 166 courses. Evaluation data from 12,004 students were captured and connected to each academic coach and course. Overall, the RN-to-BSN coaches received favorable ratings by both instructors and students alike.

Conclusion:

The use of academic coaches can help to expand capacity while delivering a high-quality educational experience. These results indicate that satisfaction with academic coaches has the potential to be very high, from both the students' and the faculty members' perspectives. [

CD160 Stimulates CD8+ T Cell Responses and Is Required for Optimal Protective Immunity to Listeria monocytogenes
Authors: Tan Catherine L , Peluso Michael J , Drijvers Jefte M , Mera Camila M , Grande Shannon M , Brown Keturah E , Godec Jernej , Freeman Gordon J , Sharpe Arlene H 
Published: August 2018

Abstract
CD160 promotes NK cell cytotoxicity and IFN-γ production, but the function of CD160 on CD8+ T cells remains unclear with some studies supporting a coinhibitory role and others a costimulatory role. In this study, we demonstrate that CD160 has a costimulatory role in promoting CD8+ T cell effector functions needed for optimal clearance of oral Listeria monocytogenes infection. CD160−/− mice did not clear oral L. monocytogenes as efficiently as wild type (WT) littermates. WT RAG−/− and CD160−/− RAG−/− mice similarly cleared L. monocytogenes, indicating that CD160 on NK cells does not contribute to impaired L. monocytogenes clearance. Defective L. monocytogenes clearance is due to compromised intraepithelial lymphocytes and CD8+ T cell functions. There was a reduction in the frequencies of granzyme B–expressing intraepithelial lymphocytes in L. monocytogenes–infected CD160−/− mice as compared with WT littermate controls. Similarly, the frequencies of granzyme B–expressing splenic CD8+ T cells and IFN-γ and TNF-α double-producer CD8+ T cells were significantly reduced in L. monocytogenes–infected CD160−/− mice compared with WT littermates. Adoptive transfer studies showed that RAG−/− recipients receiving CD160−/− CD8+ T cells had a higher mortality, exhibited more weight loss, and had a higher bacterial burden compared with RAG−/− recipients receiving WT CD8+ T cells. These findings demonstrate that CD160 provides costimulatory signals to CD8+ T cells needed for optimal CD8+ T cell responses and protective immunity during an acute mucosal bacterial infection.

Published: August 2018

Abstract
Influenza viruses represent a threat to the world population. The currently available standard of care influenza vaccines are offered for each influenza season to prevent infection and spread of influenza viruses. Current vaccine formulations rely on using wild-type Ags, including the hemagglutinin (HA) and neuraminidase (NA) proteins as the primary immune targets of the vaccine. However, vaccine effectiveness varies from season to season, ranging from 10 to 75% depending on season and on age group studied. To improve rates of vaccine effectiveness, a new generation of computationally optimized broadly reactive Ags (COBRA)-based vaccines have been developed as a next-generation influenza vaccine. In this report, mice were intranasally, i.p., or i.m. primed with reassortant influenza viruses expressing different H1N1 COBRA HA proteins. These mice were subsequently boosted i.p. or i.m. with the same viruses. Sera collected from mice that were intranasally infected and i.p. boosted with COBRA-based viruses had broad anti-HA IgG binding, hemagglutination inhibition, and neutralizing activity against a panel of seasonal and pandemic H1N1 viruses. Mice immunized with viruses expressing a seasonal or pandemic H1N1 HA protein had antisera that recognized fewer viruses in the panel. Overall, COBRA-based HA proteins displayed on the surface of a virus elicited a breadth of Abs that recognized and neutralized historical H1N1 strains as well as more contemporary H1N1 viruses.
Three-Dimensional Ameliorated Biologics Elicit Thymic Renewal in Tumor-Bearing Hosts

Published: August 2018

Abstract
Cancer-initiating/sustaining stem cell subsets (CSCs) have the potential to regenerate cancer cell populations and are resistant to routine therapeutic strategies, thus attracting much attention in anticancer research. In this study, an innovative framework of endogenous microenvironment-renewal for addressing such a dilemma has been just developed. CSCs in three-dimensional multipotent spheroid-engineered biologics were prepared with 150 Gy radiation and inoculated into 15-mo-old BALB/c and C57BL/6 mice bearing diverse advanced tumors covering Mammary 4T1, liver Hepa, lung LL/2, and colon C26 tumors and distant metastases. Subsequently, the systematic microenvironment of tumor-bearing hosts was rapidly remodeled to resettle thymic cortex and medulla rudiment as an endogenous foxn1-thymosin reprogramming TCR-repertoire for resetting MHC-unrestricted multifunction renewal. Postrenewal Vγ4γδT-subsets would bind and lead migrating CSCs into apoptosis. Moreover, TCR repertoire multifunction renewal could reverse tumor metastases from tumoricidal resistance into eventual regression as a blockade of cancer-sustaining Bmi-1/Nanog-Oct4-Sox2 renewal loop with sequent multivalent depletion of both migrating/in situ CSCs and non–stem terminal cancer cell subsets. This study represents a promising start to set up a generalizable strategy of three-dimensional biologics evoking an endogenous integral microenvironment into pluripotent renewal versus advanced cancer.
