Nationwide, 63.0% of companies consider insecurity and crime as a major problem that affects them. (INEGI, 2018). On 2018 in Guanajuato, 93.3% of companies considered it unsafe, with an increase of 38.3% over 2016 (INEGI, 2018). Their municipalities are no exception, in the case of Valle de Santiago, we seek to analyze the relationship between insecurity and violence with respect to annual sales of micro and small enterprises, the research is conducted through a cross-descriptive design, with a quantitative approach, through the questionnaire as an instrument, obtaining a sample of 550 companies. As a result of the research it was obtained that 90.7% of the directors of the micro and small companies express to be worried by the insecurity and violence that occurs in the municipality and therefore an impact is observed in the annual sales according to the calculation of the R square, obtaining 0.765. Given the importance that micro and small enterprises have for the economic development of the municipality, the issue of insecurity and violence must be considered a priority due to its growing incidence, not only at the local level.

The objective of this study was to compare the growth and production of basil plants cultivated using pumice and tezontle particles of various sizes. Pumice (jal) and tezontle were mined in Xalisco, Nayarit. Five particle sizes per material were used —size 0 = 0.1≥ ≤12 (material without particle separation); size 1 = 7.5 ≥ ≤12; size 2 = 5.0≥ <7.5; size 3 = 3.0≥ <5.0; size 4 = 0.8≥ <3.0; size 5 = 0.1≥ <0.8— and their physical properties were determined. The basil was transplanted into pots which had been filled with particles of each size. The following variables from the above-ground part of the plants were evaluated: plant height, stem diameter, and leaves, stem, inflorescence, and total dry mass; root variables were also evaluated. Size-4 particles recorded the highest values for height, stem diameter, and total dry biomass; this result was attributed to physical properties. The highest value was obtained for every variable aboveground when pumice substrate was used.

In a company of the polymer branch, located in Jilotepec, State of Mexico, presents the need to solve some problems in the manufacture of polyurethane foam such as codes 25 STD BCQ and 64 FB, which must comply with a density and compression specific. We used the experimental design of Taguchi, which allows to design experiments that usually require only a fraction of the complete factor combinations, each factor can be evaluated independently, so that the effect of one factor does not influence the estimation of another factor. Seven factors were evaluated with two levels each: index of TDI, water, polyol, amine, catalyst Z-7, silicon and methyl chloride. To calculate the density (kg/m3), each of the samples obtained was weighed on an analytical scale and the volume of each one was obtained. The compression was measured on an Instron® universal machine. The new formulation optimized for the foam 25 STD BCQ achieved a density of 14-15 kg / m3 and a compression of 27-33 lbf., While the foam 64 FB achieved a density of 23-25 kg / m3 and a compression 58- 68 lbf., These results satisfactorily meet customer specifications.

Authors: Rangel-Romero Carlos , Rojas-Garnica Juan Carlos , Hernández-Lazcano Ricardo , Moreno-Guzmán Javier Andrey
Published: August 2020

The Average Temperature Process (PAT) is modeled by an equation that is used to calculate the increase in energy needed for the refrigeration cycle, which is equivalent to the energy degradation that corresponds to the production of entropy. This work shows experimentally that the increase in entropy, taking into account the processes of heat transfer that occur in the condensation temperature and in the evaporation temperature between the mechanical vapor compression refrigeration system and the environment, is directly related to the falls of pressure presented in the suction pipe and in the compression process, as well as the heat losses that exist between the main components (evaporator, compressor, condenser and expansion throttling) and the environment. From this development, the behavior of the refrigeration cycle is evaluated in order to obtain a minimum entropy generation criterion in the main components. Analytical as well as experimental results are shown using R-134a refrigerant.

Proteínas y fibra de amaranto: Actividad sobre el metabolismo de colesterol
Authors:   , Sisti Martín Sebastián
Published: August 2020

El presente trabajo de pone en evidencia el efecto que tienen los componentes de las semillas de amaranto en animales alimentados con una dieta alta en grasa y rica en colesterol. Este efecto es dosis/tiempo dependiente y es diferencial para el caso de la fibra y la proteína. Los animales que fueron alimentados con la dieta con HA durante un tiempo corto mostraron un aumento en la excreción de colesterol y ácidos biliares por heces y una marcada disminución en el contenido de colesterol del hígado. Este efecto no se observó en los animales alimentados con la dieta con proteína de AA. Los animales alimentados durante un período prolongado con la dieta más rica en fibra HA, excretan una mayor cantidad de colesterol y ácidos biliares que los alimentados con una la dieta con proteína de AA. En este último caso los animales mostraron además un menor contenido de colesterol en hígado. Estos resultados sugieren que la fibra de amaranto ejerce un efecto importante a nivel intestinal, mientras que, las proteínas de amaranto actuarían a través de un mecanismo dual, aumentando la excreción de colesterol y ácidos biliares a nivel intestinal y, modificando el metabolismo del colesterol a nivel hepático. En los ensayos in-vitro observamos que, tanto la proteína como la fibra provenientes de semillas de amaranto impiden parcialmente que el colesterol forme parte de las micelas modelo. Este impedimento se observa a concentraciones menores cuando se utilizaron muestras de amaranto ricas en fibra aunque la fracción proteica digerida, produjo valores de desplazamiento de colesterol más altos que el resto. En el presente trabajo de tesis, confirmamos que las proteínas y péptidos de amaranto tienen la capacidad de interaccionar captar ácidos biliares y que las fracciones de péptidos con mayor carácter hidrofóbico serían las responsables de esta capacidad. Finalmente podemos aceptar nuestra hipótesis de trabajo planteada y afirmar que las proteínas y fibra de amaranto ejercen su efecto sobre el metabolismo del colesterol a través del desplazamiento del colesterol en micelas y la captación de ácidos biliares.

Published: August 2020

Este texto visa relacionar os elementos identitários de um grupo de professores(as) de História que atuam na educação básica de Belo Horizonte à constituição das identidades na América Latina, seus aspectos gerais e as políticas públicas educacionais na região. Investigou-se sobre a(s) identidade(s) profissional(is) docente(s) visando  correlacionar as temáticas presentes no texto com o relato de profissionais docentes que atuam em escolas de educação básica na região metropolitana de Belo Horizonte. Para tal, como método para a investigação, foi aplicado um questionário, com perguntas fechadas e abertas, solicitando informações de dados pessoais e percepções sobre a atividade docente. Percebeu-se que o(a) professor(a) de História da Educação Básica vai moldando sua(s) identidade(s) e, durante a fase de estabilização de Huberman (1995), o professorado já tem maior consciência de suas atribuições e contribuições para a sociedade, mesmo percebendo o movimento das políticas públicas que desprofissionalizam sua função e os fazem repensar sobre as expectativas e projeções de futuro. Percebeu-se, também, grandes problemas na área educacional e na relação dos(as) professores(as) com as políticas públicas educativas implantadas nas últimas décadas. Logo, a condição docente no início do século XXI se mostra heterogênea em compasso com as modificações no campo do trabalho do mundo capitalista e tangenciada por elementos que interferem na qualidade de vida dos(as) profissionais.

O presente estudo é parte de resultado de tese de doutorado, defendido em 2017, sob o título: Pescadores Artesanais da Z-16: relações de produção-formação e práxis política. Faz-se aqui uma análise da práxis produtiva nas relações de produção-formação dos pescadores da Colônia Z-16 de Cametá-Pa, enquanto instrumento de contestação da realidade desses sujeitos. Por meio da aplicação de entrevistas semiestruturadas (MICHELAT, 1985), e com os dados analisados com base no materialismo histórico-dialético (MARX, 2008), sustenta-se que a práxis produtiva dos pescadores vem se apresentando enquanto mecanismo de não aceitação das negações produzidas pelo modo de produção vigente e, também, enquanto luta pela transformação da realidade. Conclui reconhecendo que a práxis produtiva se revela na ação constante dos pescadores e que as próprias limitações que hoje esses sujeitos sofrem em relação à construção de uma existência plena, bem como as relações próprias do mundo interiorano no qual estão inseridos, se transformam em mecanismos potencializados no sentido de avançar para além das negações e contradições cotidianamente enfrentadas.
TRABALHO, EDUCAÇÃO E CAPITAL

O artigo discute as relações entre trabalho e educação ao longo da história no intuito de evidenciar a perpetuação da dicotomia expressa no modelo educacional vigente, sobretudo no ensino profissionalizante, que tem reproduzido a cisão entre trabalho manual e intelectual na base da sociedade capitalista. Nesse sentido, reafirma-se a necessidade da construção de uma proposta pedagógica baseada na transmissão do conhecimento historicamente acumulado pela humanidade, articulada à possibilidade de desenvolvimento integral do ser humano. Para tanto, partiu-se do pressuposto marxiano da prioridade ontológica exercida pelo trabalho em relação aos demais complexos, que torna a educação dependente em relação a este, apesar de sua autonomia relativa e determinação recíproca. A pesquisa, de natureza teórico-bibliográfica, recorreu a autores clássicos e contemporâneos, cujas interpretações conferem coesão com a proposta do referencial balizador: o marxismo. A partir da investigação foi possível apontar críticas à legitimação da dicotomia educativa através dos séculos e apontar alguns construtos teóricos fundamentais de impedimento para a formação humana omnilateral.

O primeiro caso de COVID-19 foi identificado na China no final de 2019 e rapidamente foi declarada pandemia em consequência da elevada transmissibilidade e morbimortalidade do vírus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), seu agente etiológico. O espectro clínico é altamente variável, desde sintomas respiratórios e sistêmicos leves até quadros graves com sepse, síndrome do desconforto respiratório agudo (SDRA) e disfunção de múltiplos órgãos. Postula-se que a desproporcional resposta imune do hospedeiro humano ao vírus seja responsável pelas injúrias teciduais e hiperinflamação sistêmica. Os achados tomográficos principais incluem opacidades em vidro fosco e consolidações periféricas e podem variar ao longo do curso da doença, sendo, portanto, inespecíficos. Exames diagnósticos baseiam-se na detecção de proteínas do vírus e resposta imunológica à inflamação. Agentes antivirais e drogas imunomoduladoras estão sendo testados. Até o momento, o tratamento baseia-se em terapia de suporte, controle de sintomas clínicos e manejo de complicações.

As manobras de ressuscitação cardiopulmonar (RCP) durante a pandemia de COVID-19 em pacientes internados graves é requerida mais habitualmente. De uma maneira geral, o paciente sofre a parada cardiorrespiratória em decorrência da hipóxia que a Síndrome Respiratóra Aguda Grave (do inglês severe acute respiratory sundrome – SARS) leva. Entretanto, pacientes com arritmias ventriculares e choque já estão predispostos à parada cardiorrespiratória. Entretanto, é importante a equipe médica saber quando ressuscitar ou não o paciente, principalmente em decorrência da possível falta de Equipamentos de Proteção Individual (EPIs) da equipe, o que pode levar a um risco alto de contaminação dos envolvidos. Desta forma, as etapas, equipes e protocolos devem ser seguidos à risca na salvaguarda do pacente e da equipe médica.
Penyalutan Bakteri Asam Laktat Hasil dari Fermentasi Kulit Buah Nanas (Ananas comosus) dengan Pewarna Bunga Telang (Clitoria ternatea)

ABSTRAKBakteri sebagai hasil fermentasi dari kulit buah nanas (Ananas comosus) mengandung bakteri asam laktat yang dapat berperan sebagai probiotik. Agar bakteri dinyatakan sebagai probiotik bakteri harus mampu bertahan pada pH rendah, sehingga dilakukan penyalutan menggunakan metode ekstrusi dengan polimer alginat yang diwarnai dengan ekstrak bunga telang. Penelitian ini bertujuan untuk mengevaluasi pengaruh simulasi cairan lambung terhadap viabilitas bakteri yang disalut dengan menggunakan polimer alginat dan mengevaluasi pertumbuhan bakteri pada media De Man Rogosa and Sharpe Agar (MRSA) dan Nutrient Agar (NA). Metode penelitian terdiri dari proses fermentasi kulit buah nanas, enkapsulasi menggunakan polimer alginat dengan metode ektstrusi dan uji viabilitasnya. Hasil penelitian didapatkan bahwa terjadi pengurangan jumlah bakteri dan berat enkapsul yang disebabkan oleh pH rendah. Perubahan warna enkapsul terjadi setelah dipaparkan pada larutan simulan cairan lambung. Pertumbuhan bakteri pada NA lebih banyak dibandingkan dengan medium MRSA. Hal ini dikarenakan media NA merupakan media yang tidak selektif, sehingga mikroorganisme lain selain bakteri asam laktat dapat bertumbuh. Kata Kunci: ekstrusi; enkapsulasi; fermentasi; kulit buah nanas.  ABSTRACTFermentation product of pineapple fruits skin (Ananas comosus) contains lactic acid bacteria (LAB) which can serve as probiotics. In order to be declared as a probiotic, bacteria must be able to survive at low pH, thus encapsulation was carried out using the extrusion method with alginate polymers dyed with telang extract. This study aims to evaluate the effect of simulated gastric fluid (GSF) on the viability of bacteria encapsulated with alginate polymers and evaluate bacterial growth on De Man Rogosa and Sharpe Agar (MRSA) and Nutrient Agar (NA). The research method consisted of the fermentation process of pineapple peel, encapsulation using the alginate polymers with the extrusion method and its viability test. The results of the study was obtained that there was a reduction in the number of bacteria and encapsule weight caused by low pH. There were also changes in color of the microcapsules after being exposed to GSF. The bacterial growth in the NA exceeded the growth in the MRSA medium. This is due to NA is a non-selective medium, thus microorganisms besides lactic acid bacteria can grow. Keywords: encapsulation; extrusion; fermentation; pineapple fruit skin.
PENERAPAN ASAS CONTRA LEGEM OLEH HAKIM DALAM PERKARA TINDAK PIDANA KORUPSI

Penerapan asas contra legem oleh hakim dalam perkara pidana memang menimbulkan perdebatan yang panjang, apalagi jika hal itu dilakukan terhadap perkara-perkara yang menarik perhatian publik, misalkan perkara korupsi. Permasalahan dalam penelitian ini adalah mengapa hakim menerapkan asas contra legem dalam putusan Pengadilan Tindak Pidana Korupsi pada Pengadilan Negeri Klas IA Kupang nomor : 72/PID.SUS-TPK/2016/PN.Kpg, motode pendekatan yang digunakan dalam penelitian ini adalah metode pendekatan yang lazim digunakan dalam penelitian-penelitian hukum, yaitu metode pendekatan perudandang-undangan (statute aprroach), metode pendekatan konseptual (conseptual aprroach), dan metode pendekatan kasus (case aprroach). Berdasarkan pembahasan yang dilakukan oleh penulis, maka kesimpulan yang diperoleh berkaitan dengan alasan hakim menerapkan asas contra legem dalam putusan Pengadilan Tindak Pidana Korupsi pada Pengadilan Negeri Klas IA Kupang nomor : 72/PID.SUS-TPK/2016/PN.Kpg adalah karena hakim menegakan asas ne bis in idem dan hakim yang memeriksa dan mengadili perkara tersebut menganut aliran penemuan hukum Interessenjurisprudenz (Freirechtsschule).Saran dalam penelitian ini adalah Penuntut Umum harus lebih teliti dalam melakukan penuntutan, sebab terdapat perkara-perkara yang sudah diperiksa dan diputus oleh Pengadilan dantelah berkeuatan hukum tetap sehingga akan terjadi penuntutan yang lebih dari satu kali bagi seorang Terdakwa dan Hakim sebaiknya konsisten memaknai asas ne bis in idem sebagaimana makna ne bis in idem dalam Peraturan Perundang-undangan, agar hanya penuntutan terhadap Terdakwa yang sebelumnya telah pernah dihukum (berkekuatan hukum tetap) atas perkara yang sama yang sementara dituntut yang dimaknai sebagai perkara yang t ne bis in idem
