Las políticas de atención a la pobreza en México, 1970-2001: de populistas a neoliberales
Authors: Barajas Gabriela
Published: November 2019

Mexico tiene una larga historia de politicas y programas gubernamentales de atencion a zonas pobres, la cual comienza a finales de la decada de los sesenta y llega hasta los dias actuales. Sin embargo, y a pesar de su importancia, la historia de tales programas no ha sido escrita. El presente articulo tiene como objetivo comenzar a escribir dicha historia. Para lo cual se propone una periodizacion que se desprende no solo de los procesos de rupturas y continuidades entre los programas, sino que se centra en la vinculacion que guardan estos con el modelo de desarrollo economico predominante. Se concluye que, para el caso de Mexico, las politicas de atencion a zonas o grupos de poblacion especificos en situacion de pobreza no aparecen junto con el modelo neoliberal, sino con el agotamiento del modelo anterior, el posrevolucionario. Seria hasta 1997, quince años despues cuando comienza a instrumentarse el neoliberalismo en Mexico, que aparece el Programa de Educacion, Salud y Alimentacion, el primero de su tipo acorde con el modelo neoliberal. A lo largo de la revision historica es clara la vinculacion de cada uno de estos programas con funciones de control politico y legitimacion gubernamental, por lo tanto, en este trabajo se definen no como politicas estructurales de ";combate"; sino coyunturales de atencion de la pobreza, siempre relacionadas con las cambiantes necesidades de estabilidad politica y social de los distintos gobiernos.
Microempresas de Barrio: Â¿Negocio o Subsistencia?
Authors: Márquez Patricia , Gómez Samper Henry
Published: November 2019

El crecimiento explosivo de la microempresa informal urbana durante los ultimos años ha amortiguado la alta tasa de desempleo y brindado empleo a cada vez mayor numero de trabajadores en Venezuela. Sin embargo, se conoce poco sobre su funcionamiento. Este trabajo examina la experiencia de una serie de microempresas operadas por habitantes de los barrios del area metropolitana de Caracas que han sido favorecidas con prestamos del Banco de la Gente Emprendedora (BANGENTE). Entrevistas con los correspondientes oficiales de credito y visitas a los negocios evidencian la variedad de empresas que operan y los retos que enfrentan para subsistir. Se identifican retos de orden cultural, socioeconomico e institucional, mas alla de la falta de financiamiento, que colocan a la microempresa urbana en condiciones desfavorables frente a empresas de mayor tamano. Particular interes despiertan las estrategias y practicas de gestion que despliegan algunas emprendedores exitosos, que han logrado superar los retos que se les anteponen. y convertir su negocio en pequenas empresas solventes.
Realizando lo Imaginado. La formación de una política urbana desde la investigación universitaria
Authors: Ferrer Mercedes , Quintero Carolina
Published: November 2019

El objeto de este trabajo es presentar la metodologia utilizada y los resultados de una investigacion aplicada, desarrollada desde la Universidad del Zulia (LUZ), cuyo objetivo fue promover la formacion de una politica urbana bottom up y una nueva cultura urbana asumiendo en forma colectiva la rehabilitacion de un espacio emblematico de la ciudad, el Malecon de Maracaibo. Para construir este pacto por la ciudad o politica urbana, entendida como el resultado de soluciones democraticas a problemas sentidos por la comunidad, el grupo de investigacion implanto un proceso dialogante y deliberativo con la participacion de diferentes actores sociales interesados e involucrados en la recuperacion del area central de Maracaibo. El proceso se estructuro en tres fases, Fase 1: Planificacion de la Gestion (formulacion consensuada de la politica y de la estrategia operativa), Fase 2: Construccion de Consensos(o vision compartida) y Fase 3: Ejecucion del Convenio de Gestion. Esta ultima Fase se desarrollo en dos etapas, Etapa 1: Compromiso de participacion (firma del Convenio de Gestion) y Etapa 2: Corresponsabilidad en la Gestion (Ejecucion del Convenio). Del proceso desarrollado destacan cuatro conclusiones: el modelo de gestion disenado e implantado concilio la gestion publica con la iniciativa privada y, genero un aprendizaje desde la experiencia donde, actores tradicionalmente en conflicto y compitiendo para impulsar proyectos individuales se comprometieron, a traves de la firma de un Convenio de Gestion Estrategica, a rehabilitar el Malecon de Maracaibo colectivamente; el potencial estrategico de la investigacion aplicada para generar impacto social; la emergencia de una nueva praxis universitaria posfuncionalista que integra investigacion, docencia y extension como clave del quehacer academico y, la necesidad de involucrar a diferentes actores sociales en el proceso de formacion de la politica urbana para desarrollar comunidades y ciudades sostenibles.
Hacia una nueva visión de la política social en América Latina: desmontando mitos
Authors: Kliksberg Bernardo
Published: November 2019

Los distintos analisis efectuados sobre America Latina han referido las condiciones economicas y politicas que ellos confrontan. Estos hechos han generado fuertes protestas sociales en varios paises de la region. En este trabajo se discuten algunos mitos que han condicionado el desarrollo de la politica social. Se construye un cuadro basico de los problemas sociales presentes en la region; se reflexiona sobre ocho mitos de amplia difusion, para mostrar sus efectos regresivos sobre ella. Se concluye que para construir un modelo de desarrollo integral, productivo y equitativo, este debe estar orientado por valores eticos, soportado por una alianza entre politica publica sociedad civil y organizaciones de los desfavorecidos; instrumentada de modo descentralizado, transparente y bien gerenciada; que persiga la superacion de la pobreza y la inequidad como prioridades estrategicas fundamentales.

Se discute sobre 1) la necesidad de reconocer el papel de la universidad para contribuir a mejorar la situacion actual a traves de la preparacion de jovenes profesionales; futuros gestores de las politicas de desarrollo del mundo, y 2) medida en que los conocimientos enseñados en las universidades reproducen las injusticias del mundo actual. En conclusion se requiere la creacion de una red latinoamericana de universidades y profesores, capaces de intercambiar ideas, opiniones y experiencias, con el fin de fortalecer la propuesta de reforma de la enseñanza universitaria con relacion a la etica, capital social y desarrollo.
El tema de género en las convenciones colectivas en Venezuela.
Authors: Consuelo Iranzo , Richter Jacqueline
Published: November 2019

El objetivo de este artículo es evaluar la atención que le ha prestado la convención colectiva en Venezuela a la regulación de los problemas que derivan de la condición de género y, en particular los relativos al trabajo femenino, partiendo de considerar que dicho instrumento es el más idóneo para confrontar la desigualdad de oportunidades presentes en el mercado de trabajo. Se presenta un breve diagnóstico del contexto actual de la negociación colectiva en nuestro país y los avances de la legislación en materia de la mujer en el trabajo, posteriormente se analizan las cláusulas de las convenciones colectivas de sectores claves en tres ámbitos: a) maternidad/ paternidad y cuidado infantil; b)Â condiciones de trabajo de la mujer y relaciones de género; c) equidad de género y no discriminación. Dicha investigación permitió detectar los temas sobre los cuales se ha focalizado la atención, como es el de la licencia de maternidad y aquellos donde se observan los mayores vacíos, como es el de las condiciones de trabajo. La cultura del incumplimiento, la escasa participación sindical femenina y la poca conciencia de género, son parte de los problemas que conspiran contra una mayor intervención de la convención colectiva en estos asuntos.

Published: November 2019

Se presenta una investigación que da origen a la formulación de una propuesta para organizar comunidades de práctica en la Escuela de Bibliotecología y Archivología de la Universidad del Zulia. Se fundamenta a partir de una metodología que incluye el análisis conceptual, epistemológico y empírico. Se efectuó una revisión de varios autores y se adelantó un estudio empírico que partió de la revisión de planteamientos expuestos por la Comisión Organizadora de las Jornadas de Transformación en LUZ y los resultados de un acercamiento a la realidad que se orientó hacia la detección de signos de crisis presentes en la dinámica académico-administrativa de la Escuela de Bibliotecología y Archivología de la Universidad del Zulia, para lo cual se utilizó un cuestionario que posibilitó categorizar las áreas problemas identificadas por los actores-informantes. Luego, se revisan las líneas de desarrollo académico en el área de bibliotecología y ciencias de la información existentes en universidades latinoamericanas y españolas, para concluir que la mencionada Escuela debe concebir y desarrollar un nuevo modelo organizativo, centrado en compartir el conocimiento, mediante comunidades de práctica y para lograrlo deben conformarse tres comunidades: Análisis documental y sistemas de representación del conocimiento, gerencia de la información y el conocimiento y estudios métricos de la información científica y tecnológica.Â
Forma socio-organizacional del vínculo a priori entre investigación y enseñanza de postgrado.
Authors: Fuenmayor Ramsés
Published: November 2019

Â¿Cuál es la condición de posibilidad del vínculo entre la investigación universitaria y la enseñanza de postgrado? Ante esta interrogante se escribe este artículo. Como resultado de un examen crítico de las bases lógicas de pregunta misma, ésta se transforma en “Â¿Cuál forma organizacional permite un vínculo a priori entre investigación y enseñanza?” La respuesta se concentra en la idea de “práctica” elaborada por Alasdair MacIntyre. Se argumenta cómo esa particular forma socio-laboral llamada “práctica”, unida a una cierta concepción de universidad, constituye la tierra socio-organizacional que hace posible una auténtica vinculación entre investigación y enseñanza de postgrado. Finalmente, con fines ilustrativos, se resume el modo particular como se hizo posible la vinculación entre la investigación y la enseñanza de postgrado en el caso de la Sistemología Interpretativa.Â
Nueva gerencia pública: Â¿gobierno sin política?
Authors: Guerrero Omar
Published: November 2019

Recientemente el concepto de gerencia publica (public management) ha provocado un singular debate. El proposito de este trabajo es analizar la nueva gerencia publica con el proposito de contribuir al debate. Los resultados revelan lo siguiente sobre la nueva gerencia publica: 1) Es una vision privada de lo publico, de naturaleza catalactica porque brota del pensamiento economico clasico, que la situa en el mercado para sustituir el esquema burocratico, 2) Se obstenta como nueva pero sus antecedentes son tan antiguos como la economia clasica y neoclasica, 3) En ella convergen una variedad de ingredientes pero de igual naturaleza que la hacen compleja, 4) Su arribo es consonante con los tiempos actuales cuando se proponen soluciones economicas a los problemas politicos en una atmosfera donde el estudio de la politica se distancia de la economia, 5) Son conceptos fundacionales: orientacion al cliente, privatizacion, mercado y competencia y en la reforma del sector publico: enfoque empresarial-gerencial, gerencia por objetivos y resultados y agenciacion y reduccion de costos, 6) Situada en el mercado, paradojicamente desde dentro es activada por la gerencia y da paso a reglas burocraticas, reemplazando al gobierno de los hombres, vision romantica de un gobierno sin politica.

Se concluye sobre la necesidad de adecuar la estructura organizativa a las funciones sustantivas de la universidad, facilitando la coordinacion y la ejecución de las decisiones.
El modelo burocrático inacabado después de las reformas de los 90: Â¿Funcionarios, gerentes o sobrevivientes?.
Authors: Estévez Alejandro M , Blutman Gustavo E
Published: November 2019

Las reformas del Estado de los 90 pusieron un fuerte acento en la necesidad de un cambio del modelo burocratico vigente en las Administraciones Publicas. Se enfatizaba en la necesidad de pasar de un modelo weberiano a otro de tipo ";Nuevo Management Publico"; sin tener en cuenta el grado de ";terminacion"; de los mismos. El articulo analiza ambos modelos desde la perspectiva del caso argentino, una de las reformas mas agresivas de America Latina. En este sentido se intenta contrastar tanto analisis teoricos como evidencia empirica obtenida a partir de dos investigaciones cuali-cuantitativas que se enfocan en obtener datos de ";sobrevivientes"; de la administracion publica como culturas especificas que rodean esos modelos inacabados.

Published: November 2019

Asthma is one of the commonest respiratory disease (as Jamnagar situated on sea coast has more moisture present in the air and polluting environment is increasing due to rapid industrial development i.e. industries using various chemicals/ pollutants, increases the incidences of Respiratory tract diseases) as well as a significant disease burden worldwide costing billions of dollars. The WHO estimates that there are between 15 and 20 million people with Asthma in India. The increase is likely to be particularly dramatic in India, which is projected to become the world’s most populous nation by 2050. An absolute 2% increase in the prevalence of Asthma in India would result in an additional 20 million people with the disease.  Anti-asthmatic drugs that are available in the market are expensive and have adverse effects. Thus, it is wise to look for an adjunct therapy to alleviate these problems. Therefore, the main aim of this study is to see the effect of Yoga on patterns of clinical features, peak expiratory flow rates and use of drugs in Asthmatic patients.

Yoga intervention group (Group A) showed 70.58% reduction in the use of emergency medicine while it was 68.09% in Ayurvedic conventional group (Group B). There was a 24.93% increment in the PEFR in the Group A while only 16.49% in the Group B. There was statistically significant reduction in frequency and duration of Asthma attacks in both the Groups. Yoga exercise among Asthmatic patients resulted in a decreased number of attacks and use of drugs. It also shows significant improvement in the peak expiratory flow rate in Yoga intervention Group. Further large scale study is recommended.

The use of multidimensional methods of analysis of the intra-breed variability of fat content in milk of dairy cattle
Authors: Kramarenko S. S. , Kuzmichova N. I. , Kramarenko A. S.
Published: November 2019

The analysis included data on the origin and milk productivity of 109 first-born red steppe breed, which were descendants of five bulls-offspring (Narcissus, Topol, Tangens, Neptune, and Orpheus) and were kept in SE “Plemproductor Stepove” (Mykolaiv region, Ukraine ) during the years 2001–2014. The purpose of this study was to analyze the fat content of milk during different months of lactation (MFP1, MFP2,…, MFP10) to determine latent variables that best describe the variability of dairy cows' productivity in this herd. High correlation estimates of fat milk scores in different lactation months have been established. According to the results of the Principal Component Analysis, based on the (co)variation matrix of fat content in milk, three new variables (PC1, PC2, and PC3) were identified, which accounted for about 82% of the variability of the original data. The First Main Component (PC1) explained 53.5%, Second (PC2) – 17.7%, and Third (PC3) – 10.6% of the variability of the original data, respectively. PC1 was highly correlated with MFP4-MFP10 and, thus, it distributed the animals according to their fat content level. PC2 was highly positively correlated with MFP8-MFP10 but highly negatively correlated with M FP1-MFP3 and thus it shows the rate of increase in fat content in milk during lactation. PC3 characterizes the variability of fat content in milk during the first and second half of lactation. The Linear Discriminant Analysis found that the MFP1-MFP2 and MFP9-MFP10 scores contributed most to the discrimination among the five subpopulations. The individual identification of the offspring groups of different bulls according to the cross-check classification ranged from 44.4% (Topol) to 87.5% (Orpheus) of cows, which were correctly assigned to their own group.
The sexual activity of the ram-sires, depending on their mode of use
Authors: Hrymak K.
Published: November 2019

Literary data are presented and their analysis is conducted regarding the mode of use of ram-sires and their effect on sexual activity and sperm productivity. The results of research of scientists with recommendations of optimal modes of use of fetuses for semen production and its cryopreservation in non-pairing and steaming periods are presented. According to the results of the analysis of many researchers, the activity of the sexual reflexes of the rams in the spring and summer decreases by 1.4 times compared to the winter. At the same time quantitative indicators of sperm productivity decrease. However, M.M. Aibazov (1987) experimentally confirmed that sheep-breeders of the Caucasian fine-breed and Australian merenos breed exhibit high sexual activity and produce sperm of satisfactory quality in all seasons. Similar results were obtained by British researchers in the study of sexual activity and sperm productivity of ram-sires of British breeds. A.A. Ivanov (1987) indicates the regime of use of ram sires, for five years with obtaining and subsequent freezing in the unpaired period 6 ejaculates (2 doublets 3 times) per week and in the breeding season 10 ejaculates (2 doublets 5 times) week. P.P. Kundyshev (2004) considers it possible and proposes to obtain from the breeding rams for cryopreservation and storage during the year, both unpaired and steaming periods, with daily ejaculate production. This mode, according to the author, provides a sufficiently high fertility sperm up to 50.3 percent. In the study of sexual activity and sperm productivity of ram-sires of different breeds, including the North Caucasian meat-wool, jalgin merino, Soviet merino, maniche merino, Russian meat merino, Edelbaev, polldore P.P. Mammoth and others. (2018) found that the most active were the rams of the Edinburgh breed, which took 22 seconds. ejaculate secretion, and the slowest texel breeders, which took 39 seconds to ejaculate. The rams of the other breeds listed above spent 25 to 34 seconds to ejaculate. In addition, rams of Texel breed produced the lowest activity sperm, and therefore only 19 sperm were frozen from one ejaculate, with an average of 20 to 26 sperm species tested.

Productivity and biochemical composition of feeds of grasses and herbage legumes, depending on fertilizers and growth stimulators
Authors: Savchuk L. K. , Vyhovsky I. V.
Published: November 2019

The main task of increasing the productivity of perennial grass-legumes grown on the slopes withdrawn from cultivation is to form optimal conditions for the growth and development of meadow grasses, which would ensure the highest yield of forage during the entire period of use of grass and the production of high-quality and cheap feed for public livestock. To successfully solve the problem of productivity of agrophytocenoses in scientific and practical applications, it is important to know exactly how the relationship of plants in the process of their joint growth and development, what changes occur in the chemical composition of feed when applying mineral fertilizers and growth promoters on eroded lands with steepness 6–7° under soil sedimentation of the research sites of the Rivne Institute of Agricultural Industry of NAAS of Ukraine. The results of research are presented, which showed that it is economically more effective on the slopes to grow cereals and legumes with a longer period of productive longevity, while using low rates of nitrogen fertilizers, which promotes the formation of phytocenosis, which is dominated by valuable species of cereals and perennial legumes. sowing). The introduction of mineral fertilizers and growth promoters had a positive effect on the biochemical composition of cereals. The results of studies have shown that for the creation of cereals and leguminous herbs hay use in a non-coating way, you must sow a grass mix, which includes the following herbs: alfalfa sowed (4.4 million pieces per hectare) + long beetroot horned (4.4 million pieces  per hectare) + bromus inermis (3.4 million pieces  per hectare) + lolium perenne (3.4 million pieces  per hectare) of conditioned seeds that affect the productivity and chemical composition of the herb during the growing season. On the basis of the conducted researches it is established that the influence of different doses of mineral fertilizers and growth promoters (emistim C and fumar) significantly increases the yield of dry weight and biochemical composition of feed. The results of the research are presented, which showed that during the years of the formation of cereals and leguminous grass hay use, the highest yield of dry fodder (7.5 t/ha) was collected in the variant, where mineral fertilizers were calculated at the rate of N60P60K90 with the use of fumarant plant growth stimulator and high quality, the yield of feed units was 5.25 t/ha, and digestible protein 0.82 t/ha. Years of research have shown that it is advisable to use low rates of mineral fertilizers (N60P60K90) and growth stimulants emistim C and fumar to improve feed quality.
Features of waterproofing of agricultural buildings and structures
Authors: Myniv R. M.
Published: November 2019

High groundwater levels, defects and imperfect drainage systems contribute to the active dampening of stone structures, resulting in their corrosion destruction and accelerated load loss. There are two main sources of capillary pull-up: groundwater level and so-called sprayed water. Analysis of the destruction of stone buildings shows that the major factor in their destruction is the various sources of excessive soaking (up to 50% of buildings) and, as a consequence, salinization. High groundwater levels, defects and imperfect drainage systems contribute to the active dampening of stone structures, resulting in their corrosion destruction and accelerated load loss. There are two main sources of capillary pull-up: ground water and so-called sprayed water. The humidity decreases in the bottom-up direction, as well as from the middle of the wall to its outer surfaces, which means that the capillary suction of water is in effect. Analysis of the destruction of stone buildings shows that the major factor in their destruction is the various sources of excessive soaking (up to 50% of buildings) and, as a consequence, salinization. Waterproofing has a huge impact on the durability, comfort, and cost of operating the facilities. The lack of waterproofing or its destruction, as well as the violation of the wet regime, are the cause of many defects in both individual structures and buildings in general, which require considerable cost. In the case of insulation failure or lack thereof, the soil water seeps through the walls and destroys the plaster and masonry from the outside, and after the capillary movement inside the masonry, reaches the inner layer of the plaster. Depending on the degree of threat, the appropriate type of waterproofing should be used. The quality and durability of the waterproofing layer depend on the strength of the surface preparation. Reliable adhesion to the substrate, solid coating and uniform thickness of the waterproofing coating are ensured by quality alignment, cleaning, drying, priming of the insulated surface, as well as careful preparation and execution of joints, touches and seams. To protect the foundations, walls and columns of agricultural buildings and structures from the capillary rise of moisture, we propose to cut off the inter-wall waterproofing and improve the hydrogeological conditions of the site. Waterproofing materials must comply with European standards and be certified by ISO quality management system.
To the question of amino acids and whey consumption
Authors: Korytko O. O.
Published: November 2019

The article summarizes, in a concise form, information about the importance of amino acids in the context of solving the problem of fodder protein deficiency. Amino acids, as structural components of proteins, are central to the exchange of nitrogen-containing compounds and are vital for life processes. Essential amino acids are not synthesized by the body of animals and humans, but are prepared as a part of diets. Vegetable proteins are less complete than animal proteins due to the absence of some essential amino acids. Therefore, in feeding, plant feeds are balanced by limiting amino acids, which are obtained by chemical or microbiological synthesis, or combine protein sources, taking into account their amino acid composition. Amino acids are the primary microbial metabolites that are synthesized by microorganisms in the process of life. Due to the large-scale cultivation of microorganisms in industrial conditions, amino acids, proteins, preparations for increasing the productivity of crops and animals are receive. Appropriate types of microorganisms use ammonia oxidation energy to synthesize their own organic matter. Different bacteria for the synthesis of amino acids also use nitrogen, nitrates, urea. The microbiological synthesis and accumulation of metabolites in the substrate depends on the component composition, temperature. Microbial growth is usually limited by the nutrient component. Sulfur deficiency limits the utilization of nitrogen by microorganisms. The introduction of sulfur compounds into the environment stimulates microbial synthesis in general, including sulfur-containing amino acids. As a result of incubation of the biosubstrate for 3 days at a temperature of 18 °C, the synthesis of most amino acids by microbial association was activated. Incubation with sodium sulfate (at a dose of 0.3% by weight of biosubstrate) for 3 days at 25 °C had the best stimulating effect on amino acid biosynthesis. Such a biosubstrate can be used as a source of amino acids in the form of a fertilizer or feed additive. In the XXI century anthropogenic impact causes an imbalance of the ecological situation, one of the manifestations of which is the reduction of soil fertility, which can be restored by the introduction of mineral and organic fertilizers, as well as preparations containing amino acids and stimulate seed germination, increase the yield, fertility, and fertility. Amino acids are used as additives in food production, in the treatment of diseases of different etiologies and for other purposes.

Published: November 2019

An experiment was designed with Randomized Complete Block Designed to investigate the effects of organic and inorganic nitrogen fertilizer at 90 kg N/ha on growth and leaf gas exchange in two varieties of Labisia pumila at 15 weeks after transplanting (WAT). In this study total biomass and photosynthesis (A) were significantly (P≤0.05) different among all factor. The results indicated that chicken manure enhanced the net photosynthetic rate (11.10 µmol/m²/s), stomatal conductance (0.40 mmol/m/s) and transpiration rate (5.30 mmol/m²/s) of L.pumila significantly after 31 weeks of planting. Chicken manure and Gobi indicated higher accumulation on total phenolic and total flavonoid compared to NPK green and control. Organic fertilizers (chicken manure and Gobi) were positively influenced the leaf gas exchange and growth of L.pumila as compared to the NPK green and control. This study proved that organic fertilizer can produce a quality of L. pumila compared to NPK green.

Authors: Moreno Luz , Protacio Calixto
Published: November 2019

Given the increasing global demand for pulp, there is a need to look into the prospects of increasing fiber production and shortening the harvesting cycle of abaca without sacrificing the quality of fibers for pulp production. This study investigated the chemical and pulp properties of abaca cv. Inosa fibers harvested at different stages of stalk maturity to determine their suitability for pulp and paper production.
Fibers obtained from 8-10-month-old (immature) abaca cv. Inosa possessed the desirable chemical properties for pulping, namely; low lignin and ash content, high alpha-cellulose, holocellulose and hemi- cellulose contents; which are comparable with those obtained from intermediate and mature stalks. The average pulp yield, Kappa number, viscosity, tear index and breaking length of pulps from immature stalks were already comparable with those of mature fibers and were even higher than the mature fibers of Linawaan and Laylay cultivars. Fibers of abaca cv. Inosa obtained from immature stalks were thus, found suitable for pulp and paper production.

The use of microorganisms to decontaminate the environment loaded with oil pollutants is a beneficial option for bioremediation. This study aimed to isolate, characterize and identify oil-degrading fungi from the coastal sediments of the port area of Ormoc City, Philippines, and to evaluate and compare the oil-biodegrading capabilities of these fungi. Fungal isolates were subjected to an in-vitro biodegradation assay using used engine oil as substrate. Four species of filamentous fungi were isolated and identified down to genus level. The fungal isolates include three Aspergillus spp. and one Penicillium sp. Aspergillus spp. 1 & 2 were the most efficient in degrading and utilizing the used engine oil for growth. Aspergillus sp. 1 & 2 and Penicillium sp.had mean pH values of 6.286, 6.136 and 6.32, respectively. Highest mean percent fat loss on the media and highest mean dry weights were exhibited by Aspergillus sp. 2 (mean fat loss = 77.12% and mean dry weight= 0.24g) and Aspergillus sp. 1 (mean fat loss = 69.4% and mean dry weight = 0.21g). Filamentous fungi from the coastal sediments in the vicinity of Ormoc City port area could therefore be used as potential bioremediation agents in areas contaminated with petroleum oils.

The research gap on the feasibility of basalt rock powder (BRP) and superfine sand (SS) in preparation of cement mortar is significant. Thisstudy examines probable changes occurred in the modified cement mortar due to incorporation of certain quantity of basalt rock powder andsuperfine sand in mixture proportion. The cement mortar included Portland cement, artificial sand and water as principal mixture constituents. Then, basalt rock powder and superfine sand were added as partial replacement materials for Portland cement and artificial sand respectively. Therefore, replacement percentages were 10%, 15%, 20%, 25% and 30% when the basalt rock powder replaced Portland cement and in case the artificial sand was replaced by superfine sand, 10%, 20%, 30%, 40% and 50%. Then, the strength indexes such as flexural strength, compressive strength, ultrasonic pulse velocity and dynamic elastic modulus were investigated. The results show that the presence of basalt rock powder in mixture proportion increased the flexural and compressive strengths of cement mortar however the cement mortar that contained superfine sand illustrated inadequate mechanical performance as flexural and compressive strengths decreased remarkably. Moreover, when basalt rock powder and superfine sand were included together in mixture proportion, the cement mortar’s mechanical performance declined compared to that of the reference cement mortar. Despite the fact that basalt rock powder and superfine sand weakened the cement mortar’s mechanical properties, it was found that they can be added into the cement mortar as partial replacement of Portland cement and artificial sand in the following ratios: from 10% to 25% when basalt rock powder replaces Portland cement and from 10% to 20% when artificial sand is replaced by superfine sand.

Published: November 2019

The influence of mixed rubber processing technology on Mooney viscosity and burning time was studied. The results showed that the Mooney viscosity of mixed rubber increased with the extension of the parking time, and the burning time did not change significantly. With the increase of the number of thin pass, the Mooney viscosity of mixed rubber decreases continuously, and the burning time varies with different thin pass temperature.

Objective: Our aim is to analyze the effects of 12 weeks of functional training with and without core exercises on core functional and performance indicators.

Method: This is a three-arm randomized controlled trial, which will take place over 12 weeks. Participants will be randomly grouped into three training programs, namely: functional training group, which will perform global, multi-articular, and functional exercises, with no exercises for the core; functional training + core group, which will perform a similar protocol to the functional training group, but with the inclusion of specific exercises for the core region; and core training group, which will only perform specific exercises for the core. In both moments, tests will be carried out in the following order: McGill's torso muscular endurance test battery, unilateral hip bridge endurance test, sit up test, isometric dead lift, push up, sit  to stand, functional movement screen, handgrip test, countermovement maximal vertical jump test, one repetition maximum in bench press, row  and  leg press, T- run agility test, Yo-Yo test.

Discussion: These findings will provide new evidence to aid physical education professionals in decision-making regarding exercise prescription.

Conclusion: We hypothesize that the inclusion of exercises specifically targeting the trunk in functional training protocols will lead to higher functional and core performance
Identification of the plateau in maximal oxygen consumption: proposal and application of a new method of analysis

Objective: The classic criterion for VO2máx plateau identification was proposed by Taylor et al. (1955), however, there are many critiques of this method. In this paper, we propose a new statistic-based VO2max plateau identification methodology. In addition, we aim to test for eventual differences between characteristics of the individuals who presented and those who did not present the maximum VO2max plateau.

Method: Forty-one (n = 41) physically active men participated. The subjects underwent a cardiopulmonary exercise test using ramp protocol to measure the VO2max and other physiological variables. The identification of VO2max plateau was performed by segmented linear regression with unknown breakpoints for each individual.

Results: Although 58.54% (24) of the sample presented VO2max plateau, no significant differences were observed in metabolic, ventilatory and velocity variables between the groups.

Conclusion: The methodology presents advantages, since it is adequate to analyze VO2 variations individually and because it is based on statistical techniques, which considers the continuous records of the maximal effort test, not segmenting it in sections for analysis. The comparison between groups, according to the occurrence of the plateau, showed no differences between them.

Objetivo: Se pretende analizar la modificación de la postura de los pies al ser sometidos a una situación estresante para la musculatura del miembro inferior, y valorar la capacidad de recuperación de esos pies tras un período de descanso.

Método: Se determinó el Índice de Postura del Pie (FPI-6) en 63 sujetos adultos sanos y fueron sometidos a una prueba de “Saltos con Contramovimiento (CMJ)” 30 segundos. Después, se valora el FPI-6 de cada sujeto, así como tras 15 minutos de descanso.

Resultados: Hubo cambios estadísticamente significativos en la postura del pie en ambos grupos al relacionar las tres situaciones experimentales (antes e inmediatamente después de la prueba y tras descanso). Dichos cambios presentan una magnitud del efecto fuerte entre los momentos basales y post, y entre post y descanso; mientras que es débil entre los momentos basales y descanso. Tras la prueba, existe un aumento del valor del FPI-6 respecto a la situación inicial. Tras el descanso los cambios observados fueron significativos en relación a los obtenidos tras la prueba con disminución del valor del FPI-6, aunque no volvieron a los valores iniciales previos a la prueba.

Conclusiones: La fatiga producida por la prueba CMJ afecta a los valores del FPI, produciendo un aumento de los mismos, pero no es suficiente para modificar la clasificación de la postura del pie en los grupos de pies neutros y pronados estudiados. El tiempo de descanso propuesto no fue suficiente para volver a la situación inicial.
