Study the Causes of Biodiversity Degradation and their impacts on Wildlife in a Sacred Grove Nai-Ka-Nath, Bassi, Jaipur Rajasthan[ ]


Biodiversity is the variety of all species on our planet. It includes different plants, animals, birds and micro-organisms, their genes, their habitats and all the ecosystems (forests, grass-lands, lacks, ponds, rivers, wet-lands etc.). Sacred groves are the fine example of in-situ conservation of biodiversity. Sacred groves are forest fragments, which are protected by religious communities, and have a significant religious connotation for the protecting community. Sacred groves are lost due to, anthropogenic interventions like shifting cultivation, overexploitation of forest produce, cattle grazing and changes in land use by converting forests to monoculture plantations agricultural lands and dwelling sites. Nai-Ka-Nath sacred grove situated in Jaipur district of the state of Rajasthan. The sacred grove has rich biodiversity. Several plants and animals that are threatened in the nearby areas are still well conserved in this grove. A historical temple of Bhagwan Shiva is situated in Nai-Ka-Nath grove and surrounded by hills. Due to anthropogenic activities like grazing, herb collection, timber and firewood collection, mining, pollution etc. the grove is facing the problem of degradation. These activities have been continuing ever since man started cultivation and exploitation of natural resources for livelihood. Due to these activities floral species like Gloriosa superba, Tinospora cordifolia, Ganoderma lucidum, Sida cordifolia, Commiphora wightii, Tribulus terrestris, Asparagus racemosus etc. and faunal species like Canis aureus, Hyaena hyaena, Canis lupus pallipes, Vulpes bengalensis, Hystrix indica, Naja naja, Psittacula cyanocephala, Coracias benghalensis, Pitta brachyura etc, are verge of extinction in Nai-Ka-Nath area.

This study determined the occurrence of low back pain (LBP) among 158 teen students of the University of Northern Philippines and correlated this on their exposure level to the possible LBP contributors. Through a descriptive design, a questionnaire was used, and the data was treated with frequency count, mean and multiple regression. Statistics presented that most of the respondents are 16 y.o., males, are normally postured, and yet experienced LBP once in a while, upon getting up from bed, upon standing after long hours of sitting, while carrying heavy backpacks and after strenuous sports. They are moderately exposed to metabolic contributors of LBP and have a very low disability with LBP experience in the activities of daily living (ADL’s). Meanwhile, watching tv, fishing, exposure to lipids and carbohydrates, mother’s and father’s occupation on ADL’s were also positively correlated. This study concludes that most of the teens already experienced LBP but with a slight disability on the ADL’s and this correlates on their increased exposure to aforementioned contributors. Educators, health workers, and parents must be informed of this to help prevent LBP continue into adult life.

Corrosion control in oil and gas pipelines[ ]


Corrosion is the main problem affecting the pipeline system in the United States. Briefly, corrosion refers to the destructive reaction of a metal with its environment. It takes place in the presence of a supportive medium, which is referred to as an electrolyte. Corrosion leads to problems such as leakages that lead to disasters such as fires and explosions. Therefore, it affects the safety concerns and standards held in oil and gas pipelines. There are different ways of preventing or controlling corrosion that mostly focus on the prevention of contact between the pipes and the medium or environment that leads to corrosion. Oil and gas pipes are made of low-carbon steel, which makes them susceptible to corrosion. The fatal consequences of corrosion reinforces the need to engage in constant monitoring, which aims at identifying the presence and extent of corrosion. This paper focuses on the specifics of corrosion in oil and gas pipelines, which will include a discussion of the reasons for corrosion, disadvantages and the methods of inspecting corrosion. The discussion will seek the views of different sources and individuals regarding different aspects of corrosion in oil and gas pipelines under analysis.

Parameters affecting wet ultra-fine grinding of talc ore[ ]


Fine and ultra-fine grinding have several applications in many industrial fields such as advanced ceramics, porcelain, cement, paper coating, plastic and pigments. The stirred mills are much more efficient for fine grinding and regrinding than conventional tumbling mills. Conventional mills require long retention time and tremendous energy input for micron size production. This work aims at studying the parameters affecting wet ultra-fine grinding of Egyptian talc from Shalatin locality of the Eastern Desert to produce ultra-fine product less than 10 microns. Attritor mill (Union process type 1S) is used to achieve the desired size that is utilized as a filler material for different industrial applications such as paints, plastics, paper coating, and other advanced applications. Crushed talc less than 6630 microns used as a feed. The studied parameters were media size, stirrer speed, solid content in slurry percentage by volume, and media to talc percentage by volume. The results showed that in wet grinding, about 96 % by weight with maximum size reduction d90 and d50 were 12 µm and 3.8 µm at 180 min overall grinding time. Particle size enlargement occurred after the time aforementioned. The scanning electron microscope of ultra-fine grinding showed that distortion of platy structure occurred after 180 min. Therefore, in order to keep the platy structure and crystallinity of talc in order to be used as filler material in different industrial applications, it is recommended not to grind talc for more than this time. The submicron ultra-fine grinding products of Egyptian talc could be used in different industrial filler applications such as paints, ceramic and paper coating.
