A total of 183 isolates of Klebsiella from drinking water, market vegetables, wood, sawdust, industrial effluents, and human and animal origin were examined for susceptibility to 10 antibacterial agents. Incidence of resistance to two or more antibiotics tested was: 65% of the human clinical isolates, 59% among bovine mastitis, and 24% among the nonclinical isolates. The five different multiple...

This paper shows how to use a mathematical model to predict the vibration of lightweight timber-framed floor/ceiling systems (LTFSs) caused by mechanical excitation. The LTFS considered here is made up of an upper floor layer, a cavity space with timber joists and a ceiling. These components are joined by timber battens, ceiling furring channels and ceiling clips. The vibration in the structure...

Ganoderma lucidum has a well-developed ligninolytic enzyme system, where laccase is the dominant and sometimes only synthesizing enzyme, and therefore could find an application in the delignification of abundant plant raw materials and in food, feed, paper, and biofuel production. The questions that provided the goals for the present study were whether the profile of G. lucidum laccase depends ...

In Bangladesh, there are thousands of textile-dying industries spread across the country’s many regions, majority which involve knitting and dying. The dyeing industry uses an enormous quantity water, as well colors chemicals. After dying process has been completed, they also release a significant amount wastewater. Cotton, wool, polyester fiber typically dyed with textile dyes such reactive, a...

Abstract In recent years, the treatment of dye wastewater has attracted more attention because its harmful impact on environment. Therefore, should be treated using effective methods, such as adsorption, which is widely employed to remediate many dyes from wastewater. This work studied use Laurus Nobilis Leaves (LNL) and sawdust (SD) low-cost natural adsorbents reactive blue (RB) synthetic unde...

The conversion of the cellulose into 5-HMF would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-HMF. Chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-HMF. In this paper, the sawdust has been directly degraded i...

The highest level of laccase activity (391 Ul–1), as well as significant Mn-oxidizing peroxidases production, were found in solid-state culture with grapevine sawdust as the carbon source. After purification of extracellular crude enzyme mixture of Pleurotus pulmonarius, grown in the medium with the best carbon source (grapevine sawdust), three peaks of laccase activity were noted. The results ...

Head and neck cancers account for an estimated 549,000 global cancer diagnoses each year. While tobacco use, alcohol consumption, and HPV16 infection are considered to be the major risk factors for this disease, occupational risk factors, including exposure to asbestos, have also been described, although dust exposures other than asbestos have been historically understudied. We have investigate...

Poultry litter is composted to reduce odor and pathogens and to improve its quality as a soil amendment. Organic material, e.g., sawdust, is added to increase the C:N ratio to achieve optimum degradation of organic C and retention of N through microbial biomass formation. However, the relative biodegradabilities of the organic material in poultry litter and the amendment are usually not known. ...
