Laboratory investigations were conducted to identify suitable form and to determine the suitable dose of application of osmolytes for liquid inoculant formulations of plant growth promoting rhizobacteria (PGPR) viz., Azotobacter sp., Azospirillum sp., Acinetobacter sp., Bacillus sp. and Pseudomonas sp. Osmolytes such as four grades of polyvinyl pyrrollidone (PVP), four grades of polyethylene glycol (PEG), and glycerol were added to broth at three different concentrations (0.5%, 1.0% and 2.0%). Supplementing the specific media with 2 % Glycerol for Azotobacter sp., 2 % PVP K-15 for Bacillus sp., 1 % PEG 400 for Azospirillum sp., 2 % PVP K-15 for Pseudomonas sp., and 2 % PEG 4000 for Acinetobacter sp. resulted in the highest population densities.
This review article highlights the various organs affected due to infection by a host of microorganisms resulting in the elevation of Liver Function Tests particularly liver enzymes due to infections by falciparum malaria, parasites, viral infections, dengue, measels, tuberculosis, anaplamosis etc. Kidney function progressively decrease in infections due to measles, tetanus, staphylococcus, malaria, MRSA viruses and cardiac function tests are elevated in pneumonia.
Allelopathy refers to the chemical inhibition of growth of one species by another. With the objectives of understanding allelopathic effects of sixty seven traditional rice cultivars, a field experiment and laboratory experiments were carried out in 2011 Yala season at Faculty of Agriculture, University of Ruhuna, Mapalana, Sri Lanka. Rice cultivars were transplanted according to the completely randomized block design with four replicates. Each replicate consisted of three rows of rice plants and data were collected from the middle row. After three months of transplanting, plant height (cm) and number of tillers/plant, were evaluated in traditional rice cultivars and total dry matter weight of weeds in 0.093 m 2 (1ft2) area encircled by the rice plant were evaluated in three replicates. According to the statistical analysis there were significant differences in plant height and tiller number/plant in traditional rice cultivars.
Textile testing laboratories have a number of factors to take care of, like testing samples coming in, the sample registration, testing, invoicing, reporting etc...We at KS Softech, have a system called Lab Quest - Laboratory Information Management System which is an inbuilt software meeting all the requirements of a Textile Testing Laboratory.
The experiment was conducted at the Laboratory of Agronomy Department, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during March to August 2013 to study the influence of variety and date of harvesting on changes of sugar and starch levels of potato derived from TPS at ambient storage condition. Potato variety and time of harvest had significant effect on nutritional aspects. Reducing sugar, total sugar increased with advancing storage period, whereas specific gravity, non-reducing sugar and starch content decreased with increasing storage period. Among the varieties HPS 364/67 was the best in respect of nutritional aspects. At harvest and 100 days after storage, the highest total sugar (0.61% and 0.82%) was observed from Lady Rosetta and harvest at 110 days after planting, while the lowest total sugar from HPS-364/67 and harvest at 80 days after planting. The results revealed that HPS 364/67 showed superior nutritional quality than other varieties
Microorganism may adapt with environmental stresses by altering metabolisms and structures of their physiology. Temperature is a major environmental factor that can be used to inhibit microorganisms. However, sublethal temperature stress will not kill microorganism effectively and yet microorganisms are injured. The objectives of the present study were to determine the culturability and percentage injury of Escherichia coli ATCC 25922 grown in the laboratory medium when shifting from 37°C to sublethal temperature stresses temperatures of 45°C, 40°C and 20°C at log and stationary phases. Initially, the E. coli culture was grown in Tryptic Soy Broth at 37°C for 6 hours and 18 hours to reach log phase and stationary phase, respectively before the culture was transferred to three sublethal temperature stresses and culturability were determined by using two-plating systems; TSA with and without 4% NaCl (TSAS).
Tin slag a waste product of tin smelting contains many important metals such as niobium, tantalum, manganese, iron, aluminum, titanium, etc. Niobium metal which is one of the important metals found in tin slag has successfully been extracted using leaching and electrothermal method. The tin slag was crushed and ground to very fine particle sizes of nanometer level using laboratory ball mill, piston and mortar. The particles were sieved and 150nm and 180nm particle sizes range were used for this experiment. The samples were subjected to two leaching processes using hydrochloric acid and sodium hydroxide. The residues from the leaching processes were subjected to carbonchlorination at 300oC to produce Niobium oxide. The purity of Niobium metal extracted was calculated to up to 95% which means that tin slag from Nigerian Tin Smelting Company is a good source of high quality Niobium metal.
