Human Population Concept in Present Scenario

Human population is a group of people living in a particular area at a given time. All the human beings of the world are connected biologically by the act of marriage and interbreeding. The annual population growth rate is 2.9% in Africa, which is the fastest growing region in the world. In North America it is 1.1%, in USSR is 0.5%, in Europe is 0.3%. It is believed that by 2030 China will be a population giant having 1.5 billion people and India will have 1.4 billion people. Human population is the most powerful factor in bringing about much change in the environment because of cultural evolution. Some of his activities disturb the environment. He himself tries to conserve the environment. Human population seems to be the most powerful agent in regulating the environment. The overpopulation in cities creates an ecological imbalance which leads to severe environmental crisis and shortfall of resources and environmental disturbances. This is not likely for maintaining a sustainable environment

Standardization of Free Radical Scavenging Activity of Some Indigenous Medicinal Plants by Using Thin Layer Chromatography

Thin layer chromatography is basically used to separate out plants active constituents, various dyes and chemical analysis. The present study is designed to find out free radical scavenging property with the help of thin layer chromatography. For conducting this experiment 15 medicinal plants of local region were selected. Collected plants were shade dried, grind to a coarse powder and subjected to extraction with Soxhlet apparatus followed by concentration under reduced pressure by rotatory evaporator. The Methanolic plant extract was dissolved in methanol and 1µl of extract of 50mg/ml concentration was spotted on the aluminum silica plate (1.05554.0007 spectrum, Merck Germany). It was then subjected to run in Toluene: ethyl acetate (70:20) solvent mobile phase. Run plate was removed, dried and calculated Rf values for every separated active constituent. The developed plate sprayed with DPPH (free radical scavenger) reagent at 0.1mM concentration and kept for drying few minutes. After drying the zone of inhibition seen in developing plate. Formation of zone of inhibition is due to the reaction between hydroxyl ions of DPPH and test plant extracts. Results revealed that 5 plants like Azadirachta indica leaves, Dalbergia sissoo leaves, Citrus medica leaves, Ocimum sanctum leaves and Prunus persica leaves were showed good free radical scavenging activity out of 15 medicinal plants. From the above, it can be concluded that plants having good free radical scavenging property can be used as formation of medicine to preventing ageing and for other stressful condition

Role of Women in Environment Conservation

Started in the 1960s, the worldwide environmental movements have drawn the attention of many scholars and studies have then been conducted based on varied academic standpoints. However, seldom are there adequate recognition of women\u27s contribution to the conserving of the Australian environment. This may serve as the inspirations for the author to carry out a qualitative research on South Australian women\u27s involvement in the green NGOs and to acknowledge their persistent efforts accomplished in the movement. To portray a realistic picture of Australian women\u27s participation in the environmental movement, this paper has chosen to explore the reasons or the driving forces for South Australian women\u27s involvement in the green non-governmental organizations, in an attempt to discover their perceptions of the woman-nature relationship, of the current environmental problems and women\u27s empowerment in the environmental movement. To look into the subtleness of women\u27s emotion and thoughts, this paper employs the ecofeminist perspective/perspectives which draw upon the oppression and objectification of both women and nature. Supported with the triangulation of three qualitative research methods, namely documentary review, case studies and interviews, this paper highlights. The importance of women\u27s naming of their own experiences as environmentalists and succeeds in obtaining first-hand data of their engagement in the movement. Set in a non-governmental organizational background, women interviewees in this research have been and are still working with the selected green NGOs based in South Australia. With these “third-sector” performers, women have been provided with access to influence, to contribute or even to shine in the fight against natural degradation and preserving of a livable planet. Through a close scrutiny of the interviews, the research finds out that the ten female interviewees identify at a high level with the three groups of ecofeminist thinking—liberal ecofeminism, socialist ecofeminism and cultural ecofeminism. All women express their serious concerns about environmental problems, and all have particularly confirmed the woman-nature relationship. Their witness an ecofeminist demonstration of perceptions of the cause of environmental problems, care ethics, critique of power and women\u27s rising to lead positions in environmental groups

Physico-chemical Analysis of Ground Water Quality of Kalavad Taluka of Jamnagar District(Gujarat)

Physicochemical analysis of ground water samples were collected from different places of Kalavad taluka of Jamnagar district (India). These Fifteen samples of water samples from different places were analyzed for their physicochemical characteristics. All the samples were collected from the different places. People used water for drinking and irrigation purpose these water samples from fifteen different places of Kalavad, were analyzed for their physicochemical characteristics. Laboratory tests were performed for analysis as Temperature Calcium, Magnesium, hardness, pH; Chloride, Alkalinity, TDS, sulphate, phosphate and nitrate were studied. The usefulness of these parameters in predicting ground water quality characteristics were discussed. Thus an attempt has been made to find the quality of ground water in and around Kalavad suitable for drinking purposes after proper purification

Effect of Mercuric Chloride on Hepatic Phosphatases and Transaminases in Albino Rat

Mercuric chloride is a serious health hazard and produces various disorders. However, phosphatases and transaminases are marker enzymes of hepatic toxicity. Twenty four adult albino rats have taken and divided into 4 groups. Group one for acute study, while three for subacute studies with 3 rats in each. Control was also taken with similar references. Mercuric chloride gave orally administered (LD50=9.26mg/kg b.w.) by gavage tube with distilled water. Rats were autopsized at predetermined time interval to assess hepatic toxicity. Phosphatases include alkaline phosphatase and acid phosphatase while transaminases include alanine transaminase and aspartate aminotransferase. Results revealed that ALP and ACP were significantly increased after acute and subacute treatment due to the destruction of the cell membrane of lysosomes. However, AST and ALT were also increased significantly due to toxic effect of mercuric chloride on hepatic cells. Hence, the present study demonstrates that mercuric chloride produces hepatic toxicity in the form of elevation of phosphatases and transaminases enzyme level
