Published: March 2022

El establecimiento de un plan de gestión para el aprovechamiento de los desechos del ganado en las explotaciones lecheras es un aspecto fundamental para establecer una política ambiental que conduzca al desarrollo sostenible de esta actividad productiva. La gestión inadecuada de los desechos del ganado ha conducido a problemas ambientales produciendo degradación del suelo, contaminación de aguas superficiales y subterráneas y de la atmósfera, ocasionando riesgos en la salud de los animales y del hombre. El objetivo fue desarrollar un plan de gestión integral de los desechos del ganado, dándoles valor agregado para minimizar impactos ambientales. El plan se basó en el diagnóstico de la actividad ganadera en la región de Delicias, Chihuahua a través de un censo ganadero, el uso de imágenes de satélite y de parámetros indicadores como Conductividad Eléctrica (CE), Demanda Química de Oxígeno (DQO) y nutrientes en los desechos para determinar potencial de aprovechamiento o riesgo de contaminación. La cuenca lechera cuenta con aproximadamente 58,000 cabezas de ganado que producen diariamente alrededor de 2,900 m3 de excretas, generándose aproximadamente 12,000 m3 día-1 de aguas residuales lo cual muestra el potencial de aprovechamiento. La CE y la DQO de las aguas residuales muestran valores desde 0.79 hasta 12.42 mS/ cm y de 709 a 1450 mg L-1 respectivamente indicando riesgos de contaminación en el medio ambiente. Se observa que éstas aportarán nutrientes en promedio de 26.4 y 37.8 mg/l para nitrógeno y fósforo, respectivamente. El plan de gestión incluyó prácticas de uso y manejo de los residuos y uso de tecnologías a través del establecimiento de una cultura ambiental que permitan su aprovechamiento y conduzcan al desarrollo sostenible de la región.

Distant effects of monsoon depressions on weather over west Rajasthan
Authors: MUKHERJEE A. K. , SHYAMALA B. 
Published: March 2022

Monsoon depressions are generally responsible for increased rainfall activity over northern and central parts of India during southwest monsoon season. That they also have some influence on the weather over places at quite some distance from the depression has been studied by some workers. One such effect mentioned by K.L. Sinha is that whenever monsoon depressions/lows form in the Bay of Bengal or interior and move in a westnorthwesterly direction, rain or thundershowers Occur over Jodhpur. This phenomenon of distant effects of monsoon depression on weather over west Rajasthan has been studied for the 20-year period from 1956 to 1975. It is seen that on 70% of the occasions when monsoon depressions/lows formed in the northwest Bay and crossed the Orissa coast, distribution and activity of rainfall over west Rajasthan showed a prominent increase.
An explanation for the phenomenon has been offered in this study in terms of soutl1ward shift of the mid-tropospheric trough line. Those occasions when the depressions/lows were over or near west Rajasthan have been excluded in the study.
Airmasses upto 500 mb level over the Indian summer monsoon trough area

. Rao and Desai (1973) have indicated the nature of airmasses present over India and neighbourhood during July-typical monsoon month-on the basis of India Met. Dep. Forecast. Manual Part 1-2. "Climatology of India and neighbourhood-Climate of India (1968)". In the publication "Upper Air Atlas of India and Neighbourhood" (India Met. Dep. 1972), are given (i) Normal upper air temperature and contours and (ii) Normal upper winds from which one can draw inferences about airmasses over the area. Ramage and Raman (1972) have given 850, 700 and 500 mb charts for July in Voi. 2, Upper Air Meteorological Atlas of the International Indian Ocean Expedition (IIOE) from which also inferences can be drawn about airmasses over the area in question. It is seen from India Meteorological Department (1972) upper winds charts and charts of Ramageand Raman(1972) that the axis of the monsoon trough, which extends from near Delhi to Calcutta at the surface and slope southwards with height, has on both sides the air of continental origin while according to Rao and Desai and India Meteorological Department (1972) normal upper air temperature and contour charts, the axis of the monsoon trough at 850 and 700-mb levels has moist air of oceanic origin on both sides.
The chart showing distribution of rainfall over India during July would not appear to support the inferences about airmasses drawn from charts of Ramage and Raman and India Meteorological Department upper wind charts.
Vortices embedded in 'the trough of low pressure off Maharashtra- Goa coasts -during the month of July
Authors: MUKHERJEE A. K. , RAO M. K. , SHAH K. C. 
Published: March 2022

Two troughs of low pressure are generally noticed over Indian region during the monsoon. One is the monsoon trough Over Gangetic plain persisting throughout the monsoon season. The other is of comparatively less pronounced trough persisting off the west coast of India, being most prominent during the month of July.
Vortices embedded in these troughs cause considerable amount of rainfall. While the vortices and low pressure areas associated with the monsoon trough passing over Gangetic plain have been studied extensively, those embedded in the trough off the west coast do not appear to have received enough attention. In this paper the study of latter vortices during the month of July has been conducted. The following conclusions have been arrived at.
These vortices are most prominent in the month of July. They have a tendency to form in series in first half of the month of July, (b) They form just south of Goa, (c) They move generally northwards with an approximate speed of 100 km per day. During second half of the month of July some of them are found to move northwestwards, (d) Heavy rainfall associated with them has the peculiarity that coastal stations get more rain than the Ghats, and (e) There may be an association between the formation of the series of vortices, during first half of July and the existence of an upper air cyclonic circulation between 2.1 and 3.6 km above sea level over Gujarat region and neighbourhood.
Vertical structure of the planetary boundary layer in the west Indian Ocean during the Indian summer monsoon as revealed by ISMEX data
Authors: PANT M. C. 
Published: March 2022

During the Indo-Soviet Monsoon Experiment (ISMEX) .973, closely spaced aerological measurements were obtained in the west Indian Ocean and the Arabian Sea. Based on these observations a study of the thermodynamical and kinematic structure of the atmospheric planetary boundary layer in this region is made. Under undisturbed weather conditions the planetary boundary layer is mainly divided into two sub-layers-the neutral stratified mixed layer and the cloud layer. In the region north of 10°N latitude over the Arabian Sea, a strong temperature inversion tops the boundary layer and shows a downward slope from the coast of India towards the west, thus reducing the planetary boundary layer in the western region to a mixed layer and a temperature inversion layer. In the extreme eastern region, strong convective mixing weakens the layered structure and leads to the destruction of the inversion.
A gradual increase of wind speed with height is observed in the sub-cloud layer in this region. A sharp maximum frequently occurs below 1200 m in the wind profiles in the region north of 7°N latitude over the Arabian Sea. The wind speed maximum occurs usually within the inversion layer in the western Arabian Sea and within the cloud layer in the central Arabian Sea, and is often associated with large values of wind shear at low levels.
Onset of summer monsoon in Bangladesh
Authors: MOWLA K. Q. 
Published: March 2022

The onset of summer monsoon in Bangladesh has been studied by the author in this paper with the help of (i) Rainfall in June 1976 in Bangladesh, (ii) Vertical cross-sections of zonal wind for a number of days of June 1976 along Long. 90oE with particular reference to the influence exerted by the easterly jet stream on the onset of summer monsoon in Bangladesh and (iii) The APT pictures received from NOAA-4 for a number of specific days of June 1976.
The author concludes that the onset of summer monsoon in Bangladesh is heralded by a sudden increase of rainfall and that the influence of the easterly jet stream appears to extend downwards upto the ground level, removing the westerly component of wind and establishing a secondary core of the easterly jet above Bangladesh at the time of onset of summer monsoon. The APT picture indicated approach and presence of huge masses of convective clouds over Bangladesh at the time of onset of monsoon and during the lull period of summer monsoon, these convective clouds remained away from Bangladesh.
The author believes that many of the secrets of summer monsoon of south Asia may be revealed if further understanding of all aspects of the easterly jet stream is achieved.
Relationship of the 850-500 mb thickness patterns over northern and southern hemispheres vis-à-vis the activity of the Indian summer monsoon
Authors: RAMAMURTI K. K. , SUBRAMANIAM A. H. , BISWAS N.C. 
Published: March 2022

The thickness between 850 and 500 mb over the Indian Ocean area have been determined from the SIRS data available on a real time basis. The five-day averages of thickness between the southern and northern hemisphere sub-tropical ridges, which give an idea of the main driving force for the Indian summer monsoon circulation were worked out for the monsoon period in 1975 and 1976 and their relationship with the monsoon activity examined.
The rainfall anomaly (percentage) of daily rainfall from 285 reporting stations in India having normals, the thickness difference between the locations (i) Lat. 17½ 0S, Long. 550E and (ii) Lat. 32½ oN, Long. 80°E and the actual thickness at the latter point were plotted. There is a close correspondence between the three curves. A time lag of one to two days has been noted between the variations in the thickness curves and the rainfall curve. Thus it can be said that the fluctuations in the rainfall activity of the southwest monsoon over India as a whole could be correlated with the thickness difference in the lower troposphere between the sub-tropical ridges in the two hemispheres.
Some studies of the growth of monsoon disturbances
Authors: KESHAVAMURTY R. N. , ASNANI G. C. , PILLAI P. V. , DAS S. K. 
Published: March 2022

The structure of the monsoon depression and the observed flow features prior to and at the time of monsoon depression formation (composite of 15 depressions) are examined. The composite monsoon depression (transient eddy) has a scale of 25 degree longitude and extends upto 300 mb and has the greatest intensity at 700 mb. It shows northnortheast to southsouthwest tilt in l the lower levels indicating that it may draw upon zonal kinetic energy for its growth. The disturbance has lower temperatures to its west and tilts westwards with height indicating that eddy available potential energy is not converted from zonal available potential energy by large scale advection. There appears to be a reduction of vertical shear at the time of formation of monsoon depressions and this possibly aids cumulus convection.

The profiles of potential vorticity indicate extremes (i) in the upper troposphere and (ii) at several mid tropospheric levels in the region of the monsoon trough indicating the possibility of combined barotropic-baroclinic instability. Using multi-level quasi-geostrophic model and employing the eigen value technique it is shown that the monsoon zonal current is not baroclinically unstable. A barotropic stability analysis is also done for monsoon zonal current in the lower and middle tropospheres. It yields unstable modes at lower and middle tropospheric levels with wave lengths of 20-30 deg. longitude and doubling time of 4-6 days.
Simulation of the global monsoon sequence by a simple ocean-atmosphere interaction model
Authors: WEBSTER PETER J. , LAU KA MING W. 
Published: March 2022

A simple model is utilized to study the annual monsoon sequence of an atmosphere ocean system constructed to approximate the gross features of the continent-ocean distribution of the earth. The general three-dimensional structure of the system is simplified by division into a. number of domains, so chosen as to Isolate regions of similar character or similar lower boundary conditions. The governing primitive equations are averaged in longitude between the limits of each domain and neighbouring domains interact via east-west interdomain fluxes of heat and momentum. From this process, coupled sets of two-dimensional primitive equations evolve in latitude-height plane. The oceans are represented as simple adjective mixed layers In which the vertical structure is represented by two layers and advection forced by the latitudinal density variation.
To accomplish the horizontal coupling of adjacent domains, a parameterization is developed based on the theory of slowly-varying or quasi-stationary modes. The character of the parameterization is such as to reduce to a quasi-geostrophic nature in mid-latitudes and to a longitude-height plane confinement at low latitudes, the latter consistent with an east-west Walker type solution. Coupling between the ocean and the atmosphere is accomplished by wind stress and lower boundary heating.
Results are presented for a four-domain version of the model in which solar heating is allowed to follow an annual cycle. The effect of the vastly different time scales introduced into the model by the land and ocean regions is most marked in providing a diversity of response between hemispheres at different seasons and between land and ocean domains. The most interesting features are the rapid equinoctial transitions and the development of a strong easterly jet stream in the early northern heq1isphere summer and its rapid decay In early autumn; features which the oceanic southern hemisphere does not reproduce.

Published: March 2022

Este artigo teve como objetivo realizar uma análise comparativa dos registros de notificações de violência contra mulheres das Vigilância em Saúde e Vigilância Socioassistencial no município de Jijoca de Jericoacoara, Ceará, Brasil, em 2018. Os bancos de dados utilizados foram o Sistema de Vigilância de Violências e Acidentes do Sistema de Informação de Agravos de Notificação (VIVA/SINAN), e o Mapa de Risco Pessoal e Social de Jijoca de Jericoacoara. Para caracterizar os casos de violência contra mulheres adotou-se a classificação de tipos de violência da ficha de notificação do VIVA/SINAN. Foram descritas as características epidemiológicas dos casos notificados, avaliadas similaridades e divergências e cálculo do percentual de variação entre os dois bancos de dados. A maioria dos registros de notificações de violência contra mulheres estava presente, com diferença de 2.020% entre o total de notificações de violência, resultando em cenários epidemiológicos bastante distintos retratados pelas duas fontes. Conclui-se que, apesar da Lei Federal nº 10.778 de 2003 estabelecer em âmbito nacional, a notificação compulsória em serviços de saúde, os registros de notificações realizados pela Vigilância em Saúde mostraram-se insuficientes para caracterizar a real situação da problemática da violência contra mulher.

Published: March 2022

Este trabalho tem o objetivo de mostrar resultados e análises de dados das 3 últimas questões de uma avaliação, que contou com um total de 6 questões (as 3 primeiras questões foram objeto de análise em outro artigo). A avaliação foi proposta em sala de aula de um colégio público federal localizado em uma grande cidade, capital de estado, para alunos de uma turma da 1ª série do ensino médio e foi entregue por 12 alunos (houve 10 faltas, e 6 alunos não a entregaram). O propósito que norteou o estudo foi descrever a natureza das soluções dos sujeitos - conforme o nível de mobilização do raciocínio proporcional em relação à determinação de aumentos e de decréscimos percentuais de valores e quantias - de modo a conhecer e identificar como se deu a natureza das intervenções de ensino encaminhadas pelo professor. A avaliação deu-se na aula seguinte ao término do desenvolvimento e exploração de conceitos associados ao exercício do raciocínio proporcional via conceitos pertinentes às funções lineares, durante reflexões feitas quando da resolução de questões de Matemática Financeira, ao longo de 4 aulas, duração de 40 minutos cada. Trata-se de uma pesquisa qualitativa, na modalidade pesquisa-ação estratégica, segundo a qual a análise dos dados constituiu o mote para apontar indicações a respeito da apropriação do raciocínio proporcional. Os resultados mostraram que a metodologia e os procedimentos de resolução desenvolvidos para este universo de situações pouco atraíram os sujeitos de estudo como uma alternativa de resolução.

Published: March 2022

O Brasil no início dos anos de 1990 destacou-se no cenário internacional pela adoção de ações afirmativas para pessoas com deficiência junto a empresas com mais de 100 profissionais em seus quadros de lotação. Esta pesquisa de natureza qualitativa e exploratória analisou as práticas adotadas por empresas em relação à inclusão social da pessoa com deficiência no mercado de trabalho, por meio da visão dos gestores de profissionais com deficiência a fim de apontar como a lei de cotas (8.213/91) contribui para o Objetivo de Desenvolvimento Sustentável orientado para o trabalho decente (n.8 da Agenda 2030). Como resultados a pesquisa identificou que há uma intersecção parcial entre a lei de cotas e o objetivo n.8 do ODS. Uma vez que a pessoa com deficiência consegue uma função remunerada, o elemento equidade demonstra-se uma barreira a ser transposta pelo universo laboral no que tange à progressão de carreira.

Published: March 2022

Background
Older women’s mental health may be disproportionally affected by the COVID-19 pandemic due to differences in gender roles and living circumstances associating with aging.
Methods
We administered an online cross-sectional nationwide survey between May 1st and June 30th, 2020 to a convenience sample of older adults aged ≥55 years. Our outcomes were symptoms of depression, anxiety, and loneliness measured by three standardized scales: the eight-item Center for Epidemiological Studies Depression Scale, the five-item Beck Anxiety Inventory, and the Three-Item Loneliness Scale. Multivariable logistic regression was used to compare the odds of depression, anxiety and loneliness between men and women, adjusting for relevant confounders.
Results
There were 1,541 respondents (67.8% women, mean age 69.3 ± 7.8). 23.3% reported symptoms of depression (29.4% women, 17.0% men), 23.2% reported symptoms of anxiety (26.0% women, 19.0% men), and 28.0% were lonely (31.5% women, 20.9% men). After adjustment for confounders, the odds of reporting depressive symptoms were 2.07 times higher in women compared to men (OR 2.07 [95%CI 1.50–2.87] p < .0001). The odds of reporting anxiety and loneliness were also higher.
Conclusions
Older women had twice the odds of reporting depressive symptoms compared to men, an important mental health need that should be considered as the COVID-19 pandemic unfolds.
