Abstract: A method for the synthesis of OSL grade polycrystalline mass of ceramic materials with dopant C involving source ceramic material preferably in its readily available powder form comprising the steps of melting of the said ceramic material in graphite environment including a graphite crucible/container in vacuum; and obtaining there from polycrystalline aggregate by rapid solidification of said melt to thereby provide said polycrystalline mass of ceramic materials with dopant C of optically stimulated luminescence grade. The said powder form of the ceramic material is compacted and formed into pellets before subjecting to melting.

Abstract: Presented herein is a system, method, and apparatus for firmware code-coverage in complex system on chip. A circuit for analyzing code coverage of firmware by test inputs comprises an input and a memory. The input receives an address from a code address bus. The memory stores recorded addresses from the code address bus. The memory comprises a plurality of memory locations, each of the memory locations mapped to a particular one of a corresponding plurality of addresses associated with the firmware. The contents of the memory location associated with the address received from the code address bus being incremented responsive to receipt of the address.

Abstract: The present invention relates to a process for the isolation of artemisinin, an antimalarial agent from the herb of the Artemisia annua plant, comprising of extracting the herb with ethanol, partitioning of the extract between water and hexane, followed by evaporative crystallization of artemisinin from hexane phase to produce substantially pure artemisinin.

Abstract: The invention provides a method for maximization of artemisinin yield of the plant Artemisia annua, said method comprising sowing seeds of Artemisia annua plant on raised bed nursery during second and third week of December and maintaining the moisture throughout; transplanting seedlings thus obtained bearing at least 5-15 leaves into the main field fertilized with fertilizer, preferably NPK @ 80,40,40 kg/ha to achieve a population density of 50,000 to 200,000 per ha followed by light irrigation in the second week of March and irrigation every fortnight thereafter; harvesting the crop four times by cutting the plant tops leaving 75-100 cm part of plant for further regeneration, the said harvests are performed in a manner that the first harvest is done in fourth week of May, second harvest in third week of July, third harvest in second week of September and fourth harvest in third week of October of each year; and at each harvesting time care is taken to care at least one green branch, and extracting ar

Abstract: The invention relates to a process for the isolation of compound scopoletin which is used as nitric oxide synthesis inhibitor from Artemisia annua and other plant families, said process comprising extraction of dried powdered material of different plant parts with an aqueous acetonitrite solvent in the ratio of 1:5 for 6 to 8 hrs., concentration of the extracted solvent upto 30% of its original extract under vacuum, partitioning the concentrated extract with halogenated solvent to transfer scopoletin in the non-polar halogenated solvent, drying halogenated solvent over anhydrous sodium sulphate and evaporating the solvent, crystallizing the residues in methanol and filtering the crystals, concentrating the filtrate and chromatographed on silica gel, eluting scopoletin in chloroform methanol mixture; and crystallization of the fractions containing the scopoletin to get the pure scopoletin compound.

Abstract: The present invention relates to a tissue culture process for producing a large number of genetically transformed viable mint plants in vitro. The process of the present invention employs specified pieces of an internodal segment of the stem of the mint plant as the starting material and identifies medium, culture and transformation conditions for producing a large number of genetically transformed plants. Such plants can be selected for desirable characteristics.

Abstract: The present invention relates to a tissue culture process for producing a large number of viable cotton plants in vitro from a specified tissue of cotton plant. The invention provides genotype independent, direct, multiple shoot proliferation and opens up new possibilities for micropropagation, selection of mutants and for producing genetically improved cotton plants by modern methods of agrobiotechnology and genetic engineering. The protocol provides an important step in the success of cotton improvement programmed, utilizing tissue culture technology.
