Most tanneries use conventional systems for treatment of the mixture of all production effluents. Such an approach makes it possible to meet environmental regulations, but because of the high cost of the treatment facilities, its implementation has been scarce, especially in developing countries. With the waste reduction-elimination concept in view, an alternative strategy for water management ...

This study evaluated the effect of a Probiotic mouthrinse containing nisin, a bacteriocin extracted from Lactococcus lactis on dental plaque and gingivitis in young adult population. A group of 32 subjects were randomly assigned into two groups of 16 each. The first group started using the control mouthrinse (placebo) for 2 weeks followed by a washout period of 4 weeks. This group then used the...

Introduction Pyomyositis is a primary acute bacterial infection of skeletal muscles associated with abscess formation. The use of the term “tropical pyomyositis” should be restricted to primary muscle abscess arising de novo. It should not be used to describe intermuscular abscess; abscess extending into muscles from adjoining tissues, such as bone or subcutaneous tissues; or abscess secondary ...

x In addition, the sirloin which I threw overboard, instead of drifting off into the void, didn't seem to want to leave the rocket and revolved about it, a second artificial satellite, which produced a brief eclipse of the sun every eleven minutes and four seconds. To calm my nerves I calculated till evening the components of its trajectory, as well as the orbital perturbation caused by the pre...

Introduction Impairment of bladder emptying maymanifest as complete or partial urinary retention, and be either acute or chronic. The conditions under which retention occur are many and varied, indicating there must be many different causes which effect the same end result. Acute complete urinary retention is not uncommon following surgery irrespective of the operation site and is attributed to...

In a more and more regulated and socially pressured environment, the durable management of winery effluents must take into account their characteristics and their potential impact on their natural setting. The object of this exploratory study is to establish an inventory of the microbiological composition of winery effluents coming from different treatment systems. We have observed that winery ...

DNA ligases are Mg++-dependent enzymes that catalyze the formation of phosphodiester bonds at single-strand breaks in double-stranded DNA (for review and main references up to 1992, see Engler and Richardson 1982; Lindahl and Barnes 1992). The first step in the reaction is the formation of a covalent enzyme/adenylate intermediate. DNA ligases from eukaryotes, archaea, and viruses employ ATP as ...

Background: End-stage renal disease (ESRD) patients have poor health-related quality of life (HRQOL) comparing to general population and comparable HRQOL to patients with other major chronic diseases. Poor HRQOL is associated with shorter survival. There is a limited threshold to which dialysis dose and parameters management can improve HRQOL in ESRD patients. Numerous studies have sought to fi...

In their 2000 paper, “A Note on Wittgenstein’s ‘Notorious Paragraph’ about the Gödel theorem,” Juliet Floyd and Hilary Putnam present a new analysis of Wittgenstein’s “notorious” remarks on Gödel’s first incompleteness theorem. A substantial portion of this analysis focuses on the following key claim. Let “P” be the “I am not provable” sentence from Gödel’s proof of incompleteness, and let “PM”...
