Slopes in relation to lithotectonic variations,around Kud,Kashmir Himalaya     

Kumar Ravinder  V. K. Verma 《GeoJournal》1981,5(1):61-66

Analysis of slopes entails a convenient method of natural sub-division of the surface into units for which numerical data can be obtained, for the quantitative study. Main emphasis has been laid in the present work upon the importance of studying slopes in the context of drainage basins to investigate whether or not any significant relationship exists between slope and stream-basin characteristics of the drainage basins. The main slope types that are recognizable in the field are — the cliff, the concave slope, the convex slope, and the rectilinear slope.Nature of slopes appears to have effected the drainage system of the area, and the development of slopes appear to be controlled by litho-tectonic changes.  相似文献   

Care and Global Migration in the Nursing Profession: a north Indian perspective     

Margaret Walton-Roberts  Smita Bhutani  Amandeep Kaur 《The Australian geographer》2017,48(1):59-77

ABSTRACT

Globalisation, supply–demand dynamics, uneven development, enhanced connectivity including the better flow of information, communication and the reduced cost of travel have encouraged the global integration of nursing labour markets. Developed regions of the world have attracted internationally educated nurses (IENs) because of growing healthcare needs. India, along with the Philippines, has become a key supplier of nurses in the global economy. Traditionally the supply of nurses was heavily regionalised in south India, especially Kerala, but of late Punjab, in north India, has played an increasing role in nurse training and migration as the profession has become more respected and more international. This paper uses survey and interview data to detail the recent interest in nursing as a channel for independent female international migration from Punjab, and to examine how migratory ambitions have developed over the last decade in parallel with the changing status of nursing as an internationally respected profession. We identify growing interest in international migration for nursing students and their increased intention to pursue employment opportunities in Australia and New Zealand. This research highlights how nursing and care migration are increasingly structured by international circuits of training and employment, and how such circuits alter migrant and occupational geographies on the ground in sending regions.  相似文献

Effect of contrasting climates on antioxidant and bioactive constituents in five medicinal herbs in Western Himalayas     

Tarandeep Kaur  Rohini Bhat  Dhiraj Vyas 《山地科学学报》2016,13(3):484-492

To understand the effect of climate change on constitutive antioxidant and biochemical metabolites in Western Himalayas, five medicinal herbs were selected and grown at two altitudes in Jammu (305 m) and Srinagar (1730 m) with subtropical and temperate climates, respectively. Significant variations were observed in phenols and flavonoids in Hypericum perforatum L., Matricaria chamomilla L., Thymus vulgaris L., Cynara cardunculus L. and Echinacea purpurea L. growing at two locations. High altitude temperate site show variable (up to 13 fold) increase in their content. Proteins (1.3 – 1.8 times), sugars (2.8 – 4.1 times) and free amino acid (1.04 – 1.22 times) were also higher at Srinagar (1730 m). Within these plants, H. perforatum and M. chamomilla have shown higher accumulation of phenols, xanthophylls and proline even at subtropical environment in Jammu (305 m) suggesting potential for increasing their geographical area. The results demonstrate that changing environmental conditions significantly affect the bioactive constituents, which accumulate as a defence strategy by these temperate plants. Their medicinal significance during climate change scenario has also been discussed.  相似文献   

Changes in the industrial structure of India's male working force, 1961-81     

Kaur S  Chandna RC 《Population geography : a journal of the Association of Population Geographers of India》1983,5(1-2):87-104

The post-Independence period in India has witnessed a gradual decline of some occupations and services and the emergence of others. In the present paper an attempt has been made to analyze the change in the industrial structure of India's male working force by calculating an index of change. The index so calculated for 2 decades separately (1961-1971 and 1971-1981) is portrayed cartographically. The overall low degree of change recorded by the country's male working force establishes the weakness of India's industrial infrastructure. Consequently, the secondary sector seems to have failed in generating employment opportunities on a large scale. Regionally, the peripheral areas have recorded a higher incidence of change than the interior heartland of the country. The areas that were overwhelmingly agricultural and had experienced developments in the field of agriculture alone exhibited a low degree of change in comparison to those that had experienced developments both in the field of agriculture and industry. During the last inter-censal period (1971-1981) the country recorded an accelerated rate of change in the industrial structure of its male working force. Spatially too, the increasing rate of change has spread to new regions.  相似文献   

Use of geospatial technology for delineating groundwater potential zones with an emphasis on water-table analysis in Dwarka River basin,Birbhum, India     

Raju Thapa  Srimanta Gupta  Arindam Gupta  D. V. Reddy  Harjeet Kaur 《Hydrogeology Journal》2018,26(3):899-922

Dwarka River basin in Birbhum, West Bengal (India), is an agriculture-dominated area where groundwater plays a crucial role. The basin experiences seasonal water stress conditions with a scarcity of surface water. In the presented study, delineation of groundwater potential zones (GWPZs) is carried out using a geospatial multi-influencing factor technique. Geology, geomorphology, soil type, land use/land cover, rainfall, lineament and fault density, drainage density, slope, and elevation of the study area were considered for the delineation of GWPZs in the study area. About 9.3, 71.9 and 18.8% of the study area falls within good, moderate and poor groundwater potential zones, respectively. The potential groundwater yield data corroborate the outcome of the model, with maximum yield in the older floodplain and minimum yield in the hard-rock terrains in the western and south-western regions. Validation of the GWPZs using the yield of 148 wells shows very high accuracy of the model prediction, i.e., 89.1% on superimposition and 85.1 and 81.3% on success and prediction rates, respectively. Measurement of the seasonal water-table fluctuation with a multiplicative model of time series for predicting the short-term trend of the water table, followed by chi-square analysis between the predicted and observed water-table depth, indicates a trend of falling groundwater levels, with a 5% level of significance and a p-value of 0.233. The rainfall pattern for the last 3 years of the study shows a moderately positive correlation (R ² = 0.308) with the average water-table depth in the study area.  相似文献

New evidence for two sharp replacement fronts during albitization of granitoids from northern Aravalli orogen,northwest India   总被引：1，自引：0，他引：1  

Parampreet Kaur  Naveen Chaudhri  Albrecht W. Hofmann 《International Geology Review》2015,57(11-12):1660-1685

We present new evidence of infiltration metasomatism in granitoids that were albitized in a process that produced two sharp replacement fronts, both of which are clearly visible in the field. The two fronts advanced through the original granite simultaneously, but at different rates. Here we focus mainly on the Ajitgarh intrusive in the northern Aravalli orogen of northwest India. This intrusion shows geographically well-defined metasomatic zones on the outcrop scale as well as a large volume of original ferroan granite, both of which were poorly preserved in most of the previously studied Khetri granites. Stage I metasomatism transformed the grey original granite to pink microcline–albite granite, and stage II converted the microcline–albite granite to white albite granite. Both these reaction fronts are sharp and are easily recognized in the field by their different colours. The mineralogical and chemical changes during the first stage are expressed by transformation of original oligoclase to albite, biotite (annite-rich) and hastingsite (amphibole) to hastingsite with low X_Fe values, dehydration, gain in Na, and losses in Fe and Rb. The second stage of metasomatism caused almost complete conversion of microcline to albite and complete or nearly complete disappearance of amphibole. Chemically, these changes are manifested by substantial gain in Na and extreme losses in K, Rb, Ba, Ca, Sr, Fe, and Mg. Depending on the modal abundances of amphibole, stage II albitized rocks are depleted in light rare earth elements or heavy rare earth elements or both, signifying that rare earth elements are principally hosted by mafic phases. The disparity in whole-rock δ¹⁸O values during both stages of albitization is related to the variations in modal amounts of Si-bearing phases. The replacement microstructures are in accord with the fluid-mediated phase transformations by a coupled dissolution–precipitation mechanism. The albitizing event took place at low temperatures of 350–400 °C and the fluid was metamorphic in nature.  相似文献

Characterization and prediction of stormwater runoff quality in sub-tropical rural catchments     

Puneet Pal Singh Cheema  Akepati S. Reddy  Sukhpreet Kaur 《Water Resources》2017,44(2):331-341

Due to scarcity of local data on stormwater pollution levels and rainfall-runoff generation process, very few attempts have been made towards the management of stormwater in sub-tropical rural catchments. An attempt has been made in the present study to characterize and predict the stormwater runoff characteristics using regression modeling from five rural catchments in north-west India. Stormwater samples and flow data were collected from 75 storm events. Samples were analyzed for pH, total suspended solids (TSS), 5-day biochemical oxygen demand (BOD₅), chemical oxygen demand (COD), total kjeldhal nitrogen (TKN), total phosphorous (TP), nitrate-nitrogen (NO ₃ ^- –N), total coliform count (TC), fecal coliform count (FC), Zn, Cu and Fe. It was found that size of the catchment and the land use practices influenced the stormwater quality even in predominantly rural areas, otherwise thought to be homogeneous. The results obtained were related with the antecedent dry days (ADD) and average rainfall. ADD was found to be positively correlated with pollutant loads whereas average rainfall showed negative correlation. The study highlights the importance of ADD in causing greater mean pollutant concentrations except for TKN, TP and NO ₃ ^- –N. Regression models were developed for the studied catchments to estimate mean pollutant concentrations as a function of rainfall variables. Results revealed that measured pollutant concentrations demonstrated high variability with ADD and average rainfall in small rural catchments, whereas in large catchments, factors like land use, extent of imperviousness etc. resulted in low predictability of measured parameters.  相似文献
