Sawdust is obtained from naturally and easily available which is biodegradable. The bio sorption capacity of the sawdust for hexavalent chromium was studied at different solution pH values (1.5-6), initial metal concentration (50450 mg/L), adsorbent dose (1-7 g/L). The maximum adsorption of Cr (VI) is obtained at pH 1.5, initial concentration 50 ppm and adsorbent dose 5 g/l. The adsorption of c...

The aim of this research is to investigate source coding, the representation of information source output by finite R bits/symbol. The performance of optimum quantisers subject to an entropy constraint has been studied. The definitive work in this area is best summarised by Shannon’s source coding theorem, that is, a source with entropy H can be encoded with arbitrarily small error probability ...

In the Minimum Label Spanning Tree problem, the input consists of an edge-colored undirected graph, and the goal is to find a spanning tree with the minimum number of different colors. We investigate the special case where every color appears at most r times in the input graph. This special case is polynomially solvable for r = 2, and NP-complete and APX-complete for any fixed r ≥ 3. We analyze...

in order to identify the plant parasitic nematodes associated with polianthes tuberosa in dezful regions, iran, 300 soil and root samples were collected from different parts of the region, during 2012-2014. the samples were washed and the nematodes were extracted by centrifugal flotation technique. the nematodes were fixed and transferred to glycerin, and then the permanent slides of the nemato...

The study was carried out at Vegetable Research Station, TNAU, Palur, Tamil Nadu during 2021to2022. experiment laid in Factorial Randomized Block Design (FRBD) with eight treatments and three replications. Planting materials used for the were bulbs bulblets. nutrient combinations tried foliar application of micronutrient like zinc sulphate (0.2%), Ferrous (0.5%), Copper (0.4%) Boric acid (0.2%)...

Background: Currently available radioprotectors are poorly tolerated in man and the general use of aminothiols is compromised by their side effects. This study was carried out to test and compare the radioprotective potential of cimetidine and famotidine against lethally gamma irradiated NMRI mice. Materials and Methods: Adult male NMRI mice in groups of 10 were exposed to various doses of gamm...
