Pluriactividad del trabajo femenino: recurrencias y transiciones. Un estudio de caso en Tlaxcala, México
The central axis of this paper is to present a study associated with the transformations experienced by rural families and the labor market changes, emphasizing the current role of women in the textile and clothing industry in the municipality of Tepetitla de Lardizábal, TlaxcalaIn the context of neoliberal globalization there is a redirection and decantationof women to the labor market in rural areas, thus highlighting: a) the need forthe incorporation of more domestic group members in the search for income,b) multiplication of women working hours, c) unfair and unequal work practicesin and out of home, and d) increased tension between members of the householdat the time of the decision making process related to women workingoutside the home.El eje central de este trabajo es presentar un estudio asociado a las transformaciones experimentadas por las familias rurales y los cambios en el mercado de trabajo, enfatizando el papel actual de las mujeres en la industria textil y de confección en el municipio de Tepetitla de Lardizábal, Tlaxcala.En el contexto de globalización neoliberal se aprecia una redirección y decantación de las mujeres al mercado del trabajo en los espacios rurales, poniendo de manifiesto: a) la necesidad de incorporación de más miembros del grupo doméstico en la búsqueda de ingresos, b) la multiplicación de sus jornadas de trabajo, c) prácticas poco justas y equitativas dentro y fuera del hogar con respecto al trabajo, y d) mayor tensión entre los miembros del hogar en el momento de la toma de decisiones respecto al trabajo fuera del hogar por parte de éstas
The effects of plantail peel ash on biogas production from cow dung
A study was carried out to investigate the effect of pretreatment with plantain peel ash on biogas production from cow dung. Two portable floating drum digesters of the same capacity were used for the experiment. One was filled with substrate prepared from cow dung and the second was also filled with substrate prepared from cow dung but pretreated with plantain peel ash. Results showed that 11,998 cm3 of biogas was produced from the digester that contained substrate of cow dung only while 20,493 cm3 was produced from the digester that contained substrate pretreated with plantain peel ash. This showed that the increase in the volume of biogas producedas a result of plantain peel ash addition is 8,495 cm3 which is equivalent to 70.8%
Determinants of child Labour in Crop Production (A Case Study of Anambra State of Nigeria).
Determinants of child Labour use among rural household crop farmers in Anambra State of Nigeria were studied. A multistage random sampling technique was used to select one hundred (100) respondents for the detailed study. A structured questionnaire was used to elicit information from the respondents for the study. Percentage response was used to capture objective i and iii. Objective ii was capture using Probit model analysis. The result showed that majority of the respondents were married, youthful, had moderate household size, educated and highly experienced in farming. The determinant factors to the use of child labour among rural household were relationship between the child and household heads, access to credit and educational level. The major operations accomplished by the children in the study area were bird scaring, fertilizer application and planting. The child right act should be enforced by appropriate government agencies and the offenders brought to book, free education to all children and social mobilization on change of attitude to use of child labour were recommended.

Delineamento amostral no monitoramento de reservatório de uso múltiplo utilizando reflectância acumulada em imagens Landsat 8
O uso do sensoriamento remoto para estudos em ambientes aquáticos tem se mostrado de grande valia para diversas aplicações. Uma das aplicações é a determinação da localização de coleta de amostras de campo, uma vez que as imagens de satélite apresentam atributos capazes de avaliar a variabilidade espectral da superfície da água considerando uma área extensa. Desse modo, este trabalho propôs definir um método de seleção de elementos amostrais no Lago Paranoá, localizado em Brasília-DF no Brasil, baseada na variabilidade de imagens no espectro do visível e infravermelho oriundos do sensor Landsat-8/OLI. O trabalho foi pautado na seleção de imagens em períodos sazonais distintos, as quais foram somadas, compondo um único produto denominado reflectância acumulada. Posteriormente foi aplicado um método de classificação não supervisionada que discriminou 5 classes com características distintas. Como resultado foram obtidos 16 pontos que garantiram a realização de trabalhos de campo para obtenção de variáveis limnológicas em locais que apresentam variações na qualidade da água.Palavras chave: reflectância acumulada; delineamento amostral; qualidade de água; Lago Parano
Comparison of artificial rearing systems using clinical and hematological parameters: A preliminary study
AbstractComparison of clinical and hematological profile of Anglo Nubian kids was performed under three different rearing systems. Animals were separated from their dams and rearing from birth until pre-weaning at 24 days of age. Kids were fed with goat milk, reconstituted cow powder milk and reconstituted cow powder milk with enrofloxacin in a sutbherapeutical doses. Clinical exam and blood analysis were performed at 3, 10 and 21 days of treatment. Body weight did not show significant differences between treatments. Values of heart rate, cholesterol, urea, serum alkaline phosphatase and segmented neutrophils (%) were outside reference values. However, changes could be explained by physiological state and age of the animals. The use of diet supplemented with enrofloxacin did not generate substantial benefits in the animals that received it. In addition, the use of antibiotics in farms needs to be reconsidered in order to avoid negative environmental effects
Las geotecnologías como estrategias didácticas Para la enseñanza en secundaria
El presente trabajo surge a partir del Proyecto de Extensión “Actividades de Vinculación Universidad - Colegios y Escuelas. Un espacio en común para la construcción del conocimiento geográfico”, cuyo fin es articular la actividad docente de esta Universidad con un Colegio Secundario. El propósito es acercar estrategias de enseñanza basadas en estudios de caso asociadas a las geotecnologías para abordar de manera conjunta una problemática urbana y local como los anegamientos en la ciudad de Río Gallegos. Los estudios de caso como instrumentos complejos incluyen para su desarrollo información y datos provenientes de fuentes diversas que determinan su naturaleza interdisciplinaria. Los buenos casos se construyen en torno de problemas de la vida real y generalmente corresponden a escalas de análisis conocidas para los estudiantes. La incorporación de geotecnologías como técnicas o herramientas de análisis dan valor agregado a los procesos de enseñanza-aprendizaje e incentivan el interés de los estudiantes en la ciencia y la tecnología geoespacial.El objetivo del trabajo es destacar la importancia que tienen las geotecnologías en la enseñanza de la geografía en la educación secundaria. La metodología consiste en presentar a los alumnos el problema y brindar las herramientas geotecnológicas para facilitar la detección de los cambios recientes ocurridos sobre la red de drenaje natural. La observación, análisis y evaluación de imágenes (aerofotomosaicos antiguos, imágenes satelitales, carta topográfica y modelos digitales de elevación) orienta al alumno y le permite hacer juicios basados en hechos, información lógica y fundamentada. Los resultados se contrastan con las áreas más afectadas durante los eventos de precipitación registrados durante el año 2016 sobre el plano de la ciudad.Río Gallegos se localiza en la margen sur del estuario compartido entre los ríos Gallegos y Chico. Se desarrolla en un clima templado frío- semiárido de meseta con precipitaciones medias anuales que oscilan entre 200 y240 mm; estudios recientes han demostrado que con8 mmde precipitación se registran anegamientos en distintas áreas de la localidad principalmente sobre los niveles topográficos más bajos generando alteraciones en la organización espacial de la población y pérdidas económicas. Los problemas de anegamiento en la ciudad son resultado de la alteración del sistema hídrico natural por efecto de la ocupación del suelo para uso urbano y la falta de obras hidráulicas acordes al crecimiento del ejido.Las geotecnologías como estrategias didácticas aplicadas al estudio de caso generan mayor motivación y aprendizajes significativos entre los estudiantes quienes pudieron desarrollar habilidades de pensamiento crítico y creativo.Palabras clave: Geotecnologías - Enseñanza de la Geografía - Estudios de Caso

Population density and structure of diurnal primates in Pandam wildlife park, Plateau State, Nigeria.
A survey of diurnal primate species in Pandam wildlife park, Nigeria was conducted to determine its population density and structure. Eight transect lines (2.0km length, 0.02km width) at interval of 1.0km were located as representative samples in the park within the three range stratum (riparian forest, savannah woodland and, swampy area) based on proportional to size in providing information on the primate’s species present in the park. These include (Cercopithecus mona, Erythrocebus pata, Papio anubis and, Chlorocebus tantalus). Direct method of animal sighting was employed. Data was collected and analyzed using descriptive statistics, ANOVA and diversity indices. The result showed that savannah woodland strata had more number of individual species encountered (132) and the lowest was the swampy area. Also the savannah woodland had the highest species diversity and richness while the riparian forest strata had the highest number of species evenness. More so, Cercopithecus tantalus was widespread throughout the park among other primates and Cercopithecus mona is most likely to decline even more rapidly than others since they inhabit the very tall trees. However, the variation in mean value of species sampled were not statistically significance (P>0.05). Generally, atleast one primate can be sighted in every km2 of range strata covered within the park. This census provides update information on the status of primate diversity and numbers within the park which can help to direct conservation efforts of the primates and other animals by the state government. This will further enhance the sustainability and elevation of the park to a National park.Keywords: Population status, Diurnal Primates, ecology, Pandam Wildlife Park
Effects of feeding varying levels of fufu sieviate meal based diets with Panicum maximum basal on the blood characteristics of West African dwarf goats
The effects of fufu sieviate meal based diets at 0%, 20%, 40% and 60% levels using Panicum maximum as the basal on the haematological and serum biochemical parameters of West African dwarf (WAD) goats were studied for 87 days. Thirty six blood samples were collected from the WAD goats and their haematological and serum biochemical indices were determined using Beckman Coulter Ac-T10 Laboratory Haematology Blood Analyzer and Bayer DCA 2000+ HbA1c analyzer, respectively using a completely randomized design. Packed cell volume (PCV) was better (p<0.05) at T1 than the other treatments. Red Blood Cell (RBC) and mean corpuscular haemoglobin (MCH) were numerically improved at T2, T3 and T4 than in the control group while lymphocyte increased significantly (P<0.05) with increasing levels of the test ingredient. Results on serum biochemical indices showed that serum urea, creatinine, glucose and ALP differed significantly (P<0.05) and tended to be higher in the treatment (T2, T3 and T4)groups than the control group. The study therefore revealed that inclusion of fufu sieviate in the diets of West African Dwarf goats had no deleterious effects on the haematological and serum biochemical parameters of WAD goats and could be included up to 60% in goat diets
