Isolated hamlet in Indian forest gets electricity from seed-powered generator
Deep in the tropical forests of southern India, the Kolam people were untouched by telephones, cars or television, and they went to bed at dusk because there was no electricity. Their village is still far from a road or a power line. Yet, for the past year, dozens of 40-watt light bulbs have begun to glow in the mud and bamboo huts just minutes after the sun sets. The villagers have found that electricity grows on trees _ specifically the seeds of the Karanji trees in the nearby forest, which they're turning into…
VEGETATION
The vegetation of the area has been classified as “scrub jungle”. Plants which can either adapt themselves to high temperatures or to low temperatures and discouraging conditions of soil and rainfall can be found. The trees are commonly lacking, shrubs are the dominant perennials, most of which form thickets e.g. Crotalaria burhia, Leptadenia pyrotechnica, Saricostoma pauciflorum and Zizyphus nummularia. This perhaps is the reason for a very low percentage of tree species.
The vegetation can be classified on the basis of habitats viz.
1. Vegetation of sandy areas
2. Weeds and…
Action plan for ECO-restoration of holy city of AJMER.
Ajmer city is centrally located in the state is important city from historical, religious educational, administrative and tourist point of view. Ajmer city mainly situated on Jaipur- Beawar road and important junction of meter and broad gauge railway line. In the south of city, Bhilwara city is situated. There are big industries of dyeing and printings. In the north of Ajmer city Kishangarh town is situated which is important place being marble industries. In the east of city Beawer is situated which is important commercial center and…
3. Mayo College District : Mayo College Planning District lies to the east of the city and covers the entire urbanisable area east of the Ajmer –Nasirabad railway line. Mayo College shall , however, remain its most important feature. The railway workshop complex shall continue to be the major work centres for this planning District.
4. Ramganj Planning District : Ramganj Planning District lies to the south of the walled city and covers the entire area between the Taragarh hills and Ajmer –Ahmedabad railway line. The new Sub-city Centre shall form the nucleus of this planning District with…
Growth of Ajmer City and drying 5.1 Introduction
The evolution of a city is a historical process by it self. Its image at any time is merely a cross section through a continuous stream (Blumenfield, 1982). The form and growth of the city results from the concepts in the minds of its inhabitants and also from the types of structure they build. Both are derived from pre-urban roots determined by the interaction of its site, situation, function and subsequent human activity. Cities generally do not have any common origin. A city may develop from growth of a village or it may be consciously…
Influence of salinity on RuBiSCo and PEP case contents and / or activity in Maize
Hypothesis:
1. The content and specific activity of RuBISCO and PEPC may be influenced due to salinity.
2. Whether the inhibition of RuBISCO or PEPC activity is due to reduction of amount or activity of enzymes and what is the role of other factors in protection of this.
The importance of altered metabolism under abiotic stress for example diversion of carbon to polyol biosynthesis is exemplified by the metabolic reactions originating from the Glucose-6-P pool. The levels of glycine betaine are diverse…
Chloroplasts are the major site for the production of various sugars and sugar alcohols.
However their number in cells has been found to be regulated by the sugars themselves in presence of appropriate growth regulators.
Sugars and sugar alcohols have a protective role in osmoregulation and also in protection of enzymes and pigment molecules against adverse effects of abiotic stresses. Inositol, mannitol, trehalose, sucrose and glycerol did not bring any significant alteration in the carboxylase activity of RuBISCO in Sebania sesban ( Sivakumar, 2002). However sorbitol caused a notable…

The importance of altered metabolism under abiotic stress for example diversion of carbon to polyol biosynthesis is exemplified by the metabolic reactions originating from the Glucose-6-P pool. The levels of glycine betaine are diverse in different varieties of maize (Brunk et al 1989).
A positive correlation has been found between level of endogenous glycine betaine and the degree of salt resistance in maize ( Saneoka et al.…
Salt stress is one of the major constrains that limits crop productivity worldwide ( Boyer, 1982, Queseda and Ponce 2000 ) . Agricultural productivity in many aird and semi-arid regions of the world is threatened by the occurrence of salt affected soils. Estimates show that these soils occupy at least 20 percent of the irrigated land with an annual global income loss of about US $ 12 billion ( Ghassemi et al 1995). An important category of salt affected soils, sodic and saline-sodic soils show structural problems created by certain physical processes ( slacking, swelling and dispersion of…
However for developing countries where annual income of a farm of 1 ha could be less than 50 dollars due to rainfed conditions growing local plants could be an answer to findout biofuel. Growing biofuel plants can only protect total destruction of forests as for India a population of 100 million out of which at least 50 million cook their food on firewood purchased or stolen from forests legally or illegally would lose its forest cover in less than 30 years if no biofuel crops like local crops or plants replace forest plants for fuel.
