Process of soil formation.

Soil formation Soil is formed by breaking down of rocks. This process is called weathering. The weathering may be physical, chemical ar biological. It takes thousands of years to form soil from  rocks. The river or glaciers sweep away rocks, small stones, sands, dead bodies of plants and animals. These substances collide with each other on their way and break into small particles. This process continues and soil is formed. During day time, rocks get heated and get expanded. At night, the rocks get cooled and contracted. Continuous expand and contraction causes the breaking of rocks into smaller particles. The two processes explained above are the physical weathering. Rocks break into smaller particles by chemical changes. During rainy season acid rain occurs. The acid decomposes the rocks into smaller particles. Sometimes water enters into the small crevices of the rocks. When the temperature becomes too low, the water freezes and converts into ice. The ice oc

कालो छिद्र अनन्त शक्तीको श्रोत

मानब निर्मित कालो छिद्र बाट प्राप्त हुने शक्ती तारा पुन्जहरु बिच यात्रा गर्नको लागी एक उपयुक्त उर्जा स्रोत हुन सक्छ । अन्तरिक्षबाट आएको रेडियो तरङ अध्यायन गर्दा तारा पुन्ज को केन्द्रमा रहेको कालो छिद्र ले ठुलो परिमाणमा चुम्बकिय क्षत्र उत्पादन गरिरहेको छ जुन तारा पुन्ज बाट बाहिर अन्तरिक्ष तिर प्रसारित भइरहेको छ । उक्त चुम्बकिय क्षेत्र १०० लाख प्रकास बर्ष टाढा सम्म फैलन्छ । जसले अन्तरिक्षेमा रहेका धुलाकण तथा अन्य पदार्थ हरुमा दबाब उत्पन्न गर्दछ । तेस्तै मानब निर्मित कालो छिद्र बाट निस्कने तरङ पनि टाधा सम्म पुग्न सक्छ । अन्तरिक्षको एक ठाउमा निर्मित कालो छिद्रले ठुलो क्षेत्र सम्म शक्ती फल्दछ । उक्त चुम्बकिय शक्ती लाई बिधुतिय शक्तिमा रुपान्तरण गर्ने बिशिस्ट बिधुत मोटोर बाट ठुलो मात्रामा बिधुत शक्ती उत्पदन हुन्छ । उक्त बिधुत शक्तिले अन्तरिक्ष यानहरुलाई लामो समय र लामो दुरिसम्म यात्रा गर्न मदत गर्न सक्छ । Photo: NASA

What are carbohydrates?

Carbohydrates Carbohydrates is a family of organic molecules  (hydrates of carbon) with the general molecular formula  (CH 2 O) x , ranging from simple sugars such as glucose and fructose to complex molecules such as starch and cellulose. All complex carbohydrates are built up from simple unit called monosaccharide which can not be hydrolysed to simpler structure. The types of carbohydrates are described in detailed under their own heading. Name Type Structure Location Glucose Reducing monosacch C 6 H 12 O 6 (hexose) Sweet fruits Fructose Reducing monosacch C 6 H 12 O 6 (hexose) Honey, fruits juice Lactose Reducing disacch Glucose +galactose Milk Maltose Reducing disacch Glucose +glucose Germinating grains Sucrose Non-R disacch Glucose +fructose Sugar cane Starch Polysaccharides Repeated glucose unit (linear ) Potato tuber Glycogen Non-R polysacch Repeated glucose unit  (branched) Liver Cellulose
