Social and Emotional Competencies: Vital Attribute for Teacher Aspirants

Teacher competencies in curriculum transaction is a major factor of student achievement. The affective outcomes of learning are regulated through teacher interventions and interactions in the classroom. The social and emotional development of the learner need to be ensured through teaching learning process. Teacher aspirants get various training practices in college based and school based practicals but their social skills and emotional skills are to be fostered for effective teaching. Present study is an analysis of teacher aspirants’ perception on the extent of social and emotional competencies possessed by them and to identify the challenges and concerns in practicing the social emotional skills. The study reveals that though the teacher candidates possess satisfactory level of understanding related to social and emotional competencies they fail in applying those skills in classroom contexts due to various personal and social barriers. The teacher education curriculum needs to be revamped with more tools and strategies that equip the prospective teachers to excel with social and emotional competencies.

Use of immunostimulants in aquaculture management - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

Immunostimuiant may be defined as an agent, which stimulate the non-specific immune mechanism when given alone, or the specific immune mechanism when with an antigen. Immunostimulants activate the immune system of animals and render them more resistant to infections by viruses, bacteria, fungi and parasites. They may also be active against human cancer because they activate white blood cells, which recognize and destroy tumor cells. Immunostimulants are valuable for the control offish diseases

Mangrove microflora as potential source of hydrolytic enzymes for commercial applications

678-684The purpose of this study was to isolate and characterize mangrove microflora based on their hydrolytic enzyme production. A collection of 100 microorganisms including bacteria, actinomycetes, fungi and yeasts was isolated. The ability of microbial isolates to degrade hydrolytic enzymes such as amylase, cellulase, chitinase, glutaminase, laccase, ligninase, lipase, protease and tyrosinase were tested and the potent strains were identified based on 16S rRNA and ITS sequencing. More than 90% of the isolates exhibited amylolytic and proteolytic activity. Potent isolates were identified as: Bacillus subtilis (MB1), Bacillus amyloliquefaciens (MB11), Bacillus megaterium (MB23), Bacillus mojavensis (MB28), Streptomyces galbus (MA7), Streptomyces sp. (MA3), Candida parapsilopsis (MY6), Candida etchellsi (MY1), Penicillium citrinum (MF5), Aspergillus stellifer (MF12) and Emericella sp. (MF18). These microbes as well as the enzymes are of potential importance for commercial applications as bioremediators, detergent additives and nutritional supplements

RECOMBINANT EXPRESSION AND FUNCTIONAL CHARACTERIZATION OF ANTIMICROBIAL PEPTIDE CRUSTIN FROM ARTEMIA SALINA

Universidad Nacional Agraria La Molina. Escuela de Posgrado. Maestría en Ciencias AmbientalesSe estudiaron las características físicas de los residuos sólidos domiciliarios como la generación per cápita (GPC), densidad (kg/m3) y composición física, a nivel de 519 distritos pertenecientes a las 25 regiones del Perú, para determinar indicadores específicos para el Perú y su relación con factores socioeconómicos y geográficos. Las variables independientes fueron el gasto per cápita familiar (GsPC), índice de desarrollo humano (IDH), índice de pobreza total (IPT), necesidades básicas insatisfechas (NBI) y coeficiente de desigualdad (GINI); mientras que las variable dependientes fueron la GPC, densidad y composición física de los residuos sólidos domiciliarios. Se utilizaron datos provenientes de estudios de caracterización de residuos sólidos y la base de datos actualizada al 2014 del Sistema de Información para la Gestión de Residuos Sólidos del Ministerio del Ambiente (SIGERSOL). Los valores de la GPC fueron trabajados sin actualizar y actualizados al 2015, encontrándose que la GPC promedio ponderada nacional es de 0.577 kg/hab/día y la región natural selva es la que presenta mayores valores de GPC. A nivel espacial los valores de la GPC se agrupan en algunos casos siguiendo un patrón geográfico de región natural. Para el caso de la densidad de los residuos sólidos, esta fue mucho mayor en la región selva (233.985 kg/m3), que es la que además presenta la mayor cantidad de materia orgánica en sus residuos, diferenciándose significativamente de las otras dos regiones naturales. Con respecto a la relación entre la GPC y los factores socioeconómicos, se observó que existe una relación más marcada con el gasto per cápita familiar (GsPC), aunque estadísticamente los coeficientes de determinación y correlación no eran fuertes. Por último, la tasa de crecimiento de la GPC se encontró en el rango de 0.263 % a 14.741% dependiendo del crecimiento poblacional y el ingreso económico de los habitantes.Physical characteristics such as household solid waste generation per capita, density (kg/m3) and physical composition of 519 districts within 25 regions of Peru were studied to determine specific indicators for Peru and its relationship with socioeconomic and geographic factors. The independent variables were the household per capita expenditure, human development index, total poverty index, unsatisfied basic needs and coefficient of inequality; while the dependent variables were the household solid waste generation per capita, density and physical composition of solid household waste. Data from studies of characterization of solid waste and the database updated 2014 from Information System for Solid Waste Management of Ministry of Environment were used. Household solid waste generation per capita values were worked without updating and updated in 2015, finding that the per capita generation of solid waste is 0.577 kg/person/day and the jungle region has the higher value of per capita generation. Spatially, per capita generation values are grouped in some cases following a natural geographical pattern region. In the case of the density of solid waste, this was much higher in the jungle region (233.985 kg/m3), which is the one featuring the largest amount of organic matter in waste, significantly from the other two natural regions differing. Regarding the relationship between the per capita generation of solid waste and socioeconomic factors, it was observed that her is a stronger relationship with the family per capita spending, although statistically the coefficients of determination and correlation were not strong. Finally, the growth rate of per capita generation was found in the range of 0.263 % to 14.741 %, depending on the population growth and the income of the inhabitants.Tesi

Distribution of heterotrophic bacterioplankton in the Indian sector of Southern Ocean

Study was carried out on the distribution of bacterioplankton in the Indian sector of Southern Ocean. Total Heterotrophic Bacterial (THB) counts were maximum (107x104/CFU/ml) in water samples collected from 200 m depth and lowest (15.1x103/CFU/ml) at 3730 m. Of the 250 strains isolated from the water samples, 9.2% were gram positive and 4.8% gram negative. The important genera encountered were Pseudomonas, Aeromonas, Vibrio, Acinetobacter, Micrococcus, Staphylococcus, Corynebacterium, Flavobacterium, Chromobacterium, Moraxella, Bacillus and Planococcus. Most of the isolates (94%) were capable of lipase production followed by gelatinase (40%) and amylase (32%)

Stress responses and vibriosis induced by petroleum hydrocarbons in the penaeid shrimp Metapenaeus dobsoni (Miers)

Experiments with juveniles and subadults of the penaeid shrimp Metapenaeus dobsoni (Miers) subjected to lethal and sublethal toxicity tests revealed that toxicity of the water accommodated 6action (WAF) of Bombay High Cmde were dose-, time-, size- and moult stage-dependant. 13-15% of shrimps (size 30- 35 mm) exposed to 1 ppm and 5-8% of shrimps exposed to 4 ppm beyond 18 days in a 30-days moulting pattern experiment developed symptoms of vibriosis. It is significant that the shrimps exposed to 8 ppm and those maintained under control conditions did not show any signs of vibriosis. A chitinoclastic Vibrio species was isolated from diseased individuals and Kochs Postulate was successfully proved. Chronic exposure of shrimps to low sublethal doses of petroleum hydrocarbons was found to render them susceptible to vibriosis
