Abstract

Medicinal plants also play an important role in the lives of rural people in India with few health facilities. The plants that possess therapeutic properties or exert beneficial pharmacological effects on the animal body are generally designated as "Medicinal Plants". They play a significant role in providing primary health care services to rural India. They serve as therapeutic agents as well as important raw materials for the manufacture of traditional and modern medicine. Substantial amount of foreign exchange can be earned by exporting medicinal plants to other countries. In India there are 880 medicinal plants species involved in all India trade. Of this, 48 species are exported and about 42 spices are imported. The Ministry of Environment and Forests, Government of India, reveals that there are over 8000 species of medicinal plants grown in the country. About 70 percent of these plants are found in the tropical forest; spread across the Western and Eastern Ghats. The Export-Import Bank of India, in its report for the year 1997, puts medicinal plants related trade in India at $.5.5 billion and the same is growing rapidly. According to World Health Organisation (WHO) the international market of herbal products is around $6.2 billion, which is poised to grow to $5 trillion by the year 2050. Unfortunately, India's share in the global medicinal plants related export trade is just 0.5 percent. The export of Medicinal plants is Rs.33453.23 lakhs during 1991-92 to 2002-2003. Its overall trend has been increased in 0.21 percent. And the average Import of Rs.2827.01 lakhs. Also its trend has been increased in 0.39 percent.

Abstract

The economic development of any developing country depends on its self-reliance in energy needs. The current energy requirement of the country necessitates search for alternative renewable resources also which are renewable safe and non-polluting. The souring of alternative renewable resources also gains to most priority in view of uncertain suppliers and frequent like in price of crude oil in the international market. In recent times, the world has been confronted with an energy crisis due to depletion of resources and increased environmental problems. The situation has led to the search for an alternative fuel, which should be not only sustainable but also environmental problems. The situation has led to the search for an alternative fuel, which should be not only sustainable but also environment friendly. This alternative diesel fuel can be termed as bio-diesel. This fuel is biodegradable and non-toxic and has low emission profiles as compared to petroleum diesel. This fuel is biodegradable and non-toxic and has low emission profiles as compared to petroleum diesel. The study based on secondary data and the study aimed to attempt the environmental impact of Biodiesel and the cost of cultivation for jatropha in Salem district Tamil Nadu.

Abstract

The shift from behaviourism to cognitivism in educational physiology has replaced an increasing responsibility on learners for their own learning and self regulated learning has become a frequent area of educational research. In this context, the study conducted a Quasi-Experiment to examine the efficiency of task-based learning (TBL) and traditional instructional approaches on various facets of students self regulated education, including motivation and learning strategies with help of MSLQ. Participants included 61 Periyar University PG students from 2 Intact classes (TBL&non-TBL) Instructed by the same environmental economics teacher. Non-TBL group with teacher-centred, text bookoriented traditional instruction; they taught the experimental group with task based learning in which students worked with ill-structured problems. Results revealed that TBL students had higher levels of intrinsic goal orientation, task value, use of elaboration learning strategies, critical thinking, metacognitive self-regulation, effort regulation and peer learning compared with control-group students.

Abstract

The electronic industry is the world's largest and fastest growing manufacturing industry. During the last decade, it has assumed the role of providing a forceful leverage to the socio- economic and technological growth of a developing society. The consequence of its consumer oriented growth combined with rapid product obsolescence and technological advances are a new environmental challenge-the growing menace of "electronics waste" or "e waste" that consists of obsolete electronic devices. The production of electrical and electronic devices is the fastest growing sector of the manufacturing industry in industrialized countries. At the same time, technological innovation and intense marketing engender a rapid replacement process. Every year, 20 to 50 million tones of electrical and electronic equipment waste ("e-waste") are generated world-wide, which could bring serious risks to human health and the environment. The paper highlights the emerging problem of health and environmental impact of e-waste.
