Mining as you know has attained a very negative connotation to it in India. Mr. S.Vaikundarajan is the owner of the country’s most prestigious heavy mineral mining company in India named VV Minerals, India. In this article he tries to provide some clarity on the same.
Ocenjujuci rezultate I sv. rata, kao oslobodjenje ipobedu demokratije nad autoritarizmom ("mracnim vekovima"), znaci ponistenje nauke u istorijji i prelazak u politikantstvo. Svakako, kraj rata je doneo slobodu okupiranim zemljama i narodima ali i razaranje drzavnosti, pre svih, Rusije i Nemacke (koja, do danas nije povratila svoj suverenitet). Posebno, jos tokom rata, pod Kerenskim ("slucajno",sluzbenikom MI6), pre dolaska Lenjina, Trockog, ... i komunista na vlast, toko prvih meseci 1917, u potpunosti je razgradjena drzavnost (njene institucie) Rusije, kao i nemacke i austrijske carevine(i dodatno, turske).
Most agronomic soils contain large reserves of total phosphorus [P], but the fixation and precipitation of P cause P deficiency, and in turn, restrict the growth of crops severely. Phosphorus replenishment, especially in sustainable production systems, remains a major challenge as it is mainly fertilizerdependent. Though the use of chemical P fertilizers is obviously the best means to circumvent P deficiency in different agroecosystems, their use is always limited due to its spiralling cost. A greater interest has, therefore, been generated to find an alternative yet inexpensive technology that could provide sufficient P to plants while reducing the dependence on expensive chemical P fertilizers. Among the heterogeneous and naturally abundant microbes inhabiting the rhizosphere, the phosphate solubilizing microorganisms (PSM) including bacteria have provided an alternative biotechnological solution in sustainable agriculture to meet the P demands of plants.
A pot experiment was conducted in glass house conditions for 120 days to study the effects of phosphorus solubilizing Gram-positive bacteria on plant growth, nutrient uptake and yield of cowpea (Vigna unguculata). Among all twelve bacterial treatments, the strain Bacillus spp (B3) has shown the greatest shoot length 67.70 cm, root length 60.5 cm and total dry weight 4.57 g plant -1 after 45 days of sowing. Similarly, in the same treatment the shoot length, root length and total dry weight were found 162.36 cm, 60.5 cm and 128.49 g plant -1 , respectively at harvesting and total yield was obtained 23.34 g plant -1 , which was significantly greater than all other treatments and uninoculated control treatments containing single super phosphate (SSP) and rock phosphate (RP) as phosphorus sources (7.93 g plant -1 and 3.81 g plant -1 respectively). The strains Bacillus thurengensis (T1 and T6) also have indicated a significant increase in above parameters
This research work was carried out to investigate the proximate and mineral composition of some traditional vegetables in Akwa Ibom State, Nigeria. These vegetables include: Talinum triangulare, Hensia crinita, Cucurbita maxima and Lasianthera africana. The vegetables were washed in potable water to remove unwanted matters and were analyzed for proximate and mineral content. All analyses were carried out in three replicates and the mean data were presented on tables using the spread sheet Microsoft Excel. Talinum triangulare had the highest protein content (56.72%) and moisture content (80.11%) but had the lowest content of ash (6.31%), crude fibre (2.96%) and carbohydrate (6.91%). Ash and crude fibre were present in low quantities in Talinum triangulare, Hensia crinita, and Lasianthera africana, except Cucurbita maxima which had the highest composition of ash (14.06%) and crude fibre (9.37%). Mineral composition (Potassium (K), Calcium (Ca), Magnesium (Mg) and
- The present investigation was carried out at field trail of Main Experimental Station, Vegetable Science N.D.U.A. & T., Kumarganj, Faizabad (U.P.) during 2011-12 to study the performance of turmeric cultivars. Cultivar NDH-7 and NDH-8 was found superior in growth characteristics such as plant height, yield of rhizome/plant. NDH-8 found tallest (111.2 cm) while, yield of rhizome per plant was recorded in NDH-7 (303.00 g). The results showed that moisture, mineral, curcumin and essential oil ranged from 9.4 to 12.2 per cent, 3.39 to 5.30 per cent, 3.7 to 5.9 per cent and 3.32 to 8.19 per cent, respectively. NDH-7, NDH-8 and Prahba were found superior among all cultivars and variety.
Without heavy minerals, a vast range of everyday domestic and vital industrial products would just not exist. On an average day you will probably come in contact with atlease 100 items that have been manufactured from industrial minerals.
Many times you face with car paint problems, such as car’s paint getting chipped off due to one reason or other. This can happen by chance when your car scratched past against a wall or a bush, or a lorry truck tossed few marble size stone chips on your car’s hood while changing lanes, ripping off the car’s paint on several places.
VV College of Engineering was established in the year 2010. The Chairman Mr. S Vaikundrajan is also the owner of VV Minerals, India which is the largest heavy mineral mining company in India. The college is located in Tirunelveli.
VV Mineral, Mining a two-decade-old company, has been mining beach sand minerals on the Kanyakumari coast. The company doesn’t have the technology to separate thorium from monazite, a rare earth ore found in the area, a claim verified by the Atomic Energy Regulatory Board (AERB).
