conclusions there was a moderate level of knowledge, practices, perceives and beliefs in nurses and students for the importance of hand hygiene. compliance with the importance of hand hygiene in infection control is complex, and perceptual factors concerning hand hygiene, in addition to an individual’s knowledge could affect the behaviors related to hand hygiene compliance. background the curre...
The bioavailability and mobility of copper (Cu) in soil play a crucial role its toxicity impact on organisms. Humic substances, with their abundant functional groups unique pore structure, have demonstrated the ability to effectively mitigate toxic effects heavy metals soil. This study explores potential soluble humic substance (HS) derived from leonardite for Cu removal contaminated soils. var...
The influences of stock consistency on the kappa number, residual alkali of pulp, flow direction of lignin, chemical oxygen demand, oxidation with dichromate (CODCr), and five-day biochemical oxygen demand (BOD5) in effluents were investigated in a washing process. Compared with 15% stock consistency, 35% stock consistency could lead to a decrease of at least 25% in the consumption of washing w...
Many people do not wash their hands when the behavior in which they engage would warrant it. Most research of hand washing practices to date has taken place in high-traffic environments such as airports and public attraction venues. These studies have established a persistent shortcoming and a gender difference in hand washing compliance. Using field observations of 3,749 people in a college to...
Cell/bead washing is an indispensable sample preparation procedure used in various cell studies and analytical processes. In this article, we report a standing surface acoustic wave (SSAW)-based microfluidic device for cell and bead washing in a continuous flow. In our approach, the acoustic radiation force generated in a SSAW field is utilized to actively extract cells or beads from their orig...
Rajasthan is one of the main mineral potential state of India. During the last 30 years it has witnessed enormous expansion of mining industries, but mining of most of the minor minerals coupled with changing climate has posed serious problems to the environmental fabric in the state, apart from base metal beneficiation plants. Groundwater is also being polluted day-by-day by effluents generate...
In this thesis, companies using returnable plastic packaging are investigated from a green logistics’ perspective, focusing on the washing process performed after they are used. Returnable plastic boxes used to carry components are, in some cases, washed systematically to secure customer requirements. The purpose of this master thesis is to describe existing flows of returnable plastic boxes by...
