Gum polysaccharides are comprised of different monosaccharide units joined together by O-glycosidic linkages. The structural diversity of different polysaccharides is due to differences in degree of polymerization, monosaccharide composition, chain shapes, and linkage types. Gum polysaccharides are commonly used in both food and nonfood industries as stabilizers, thickening and gelling agents, ...

background: based on the economical and environmental concepts, the main purpose of the industrial waste management is reducing the production of these materials which is accessible by developing strategies of reuse, waste recycle and upgrading the technologies. accurate investigation of the quality and quantity of the industrial waste is the basis of the industrial waste correct management. th...

concentrations of eight metals namely, cr, mn, fe, co, ni, cu, zn and pb were examined in the surface sediments of discharge channels of six industries in lagos using x-ray fluorescence spectrometry.these channels drain into the isolo canal which empties into the lagos lagoon and eventually into the atlantic ocean. this study was conducted to detect any contamination levels within the sediments...

Due to global competition in manufacturing industries scenario the conventional machining processes have been replaced by advanced non conventional machining process. Several advanced non-conventional machine tools are available specifically computer numerical control (CNC) turning is the major used machine tool in metal based industries. Now days, due to the increasing demand of the higher pre...

BACKGROUND This study focused on respiratory symptoms due to occupational exposures in a contemporary general population cohort. Subjects were from the Dutch Monitoring Project on Risk Factors for Chronic Diseases (MORGEN). The composition of this population enabled estimation of respiratory risks due to occupation from the recent past for both men and women. METHODS The study subjects (aged ...

Complexing agents are extensively applied in many fields of industry. They are used to provide effective controlling trace metal ions in cleaning industries, textile, pulp and paper production, water treatment, agriculture, food industries, etc. Recently, the low biodegradability of these ligands and their accumulation in the environment has become a cause for concern. Therefore, replacement of...

A new comprehensive data linkage system for the detailed investigation of occupational cancer has been established in the Danish Cancer Registry, providing employment histories back to 1964. All 382 cases of cancers of the sinonasal cavities diagnosed between 1970 and 1984 and kept on file in this data linkage system were analysed using standardised proportional incidence ratios (SPIR) to scree...

Introduction Prostate cancer (PCa) is the most common cancer among Canadian men. Age, a family history of PCa and ancestry are the only recognised risk factors, but a role for environmental influences is suspected. Objective To explore the relationship between occupational and industry titles, and PCa risk. Methods PROtEuS (Prostate cancer & Environment Study) is a case-control study of PCa in ...

OBJECTIVES Participatory Action-Oriented Training (PAOT) has been known as a practical training methodology for improving health and safety at work, particularly for small- and medium-sized enterprises (SMEs). Our hypothesis is that PAOT is a better approach than a traditional local method, and the objective of this study was to evaluate the efficacy of PAOT and to make suggestions for improvem...
