BACKGROUND The common causes of textile dermatitis are formaldehyde resins and disperse dyes. There are various methods to detect the presence of formaldehyde in clothing. AIM To detect the presence of formaldehyde in various types of textiles by the chromotropic acid method and to assess the effect of washing on the formaldehyde content. METHODS Twenty randomly selected textiles from a loc...

In recent years, biodegradable and alternative biodiesel has attracted increased attention worldwide. Producing biodiesel from biomass involves critical separation and purification technology. Conventional technologies such as gravitational settling, decantation, filtration, water washing, acid washing, organic solvent washing and absorbent applications are inefficient, less cost effective and ...

INTRODUCTION Inadequate hand-washing facilities have been reported as a barrier to hand washing. This study aimed to evaluate the availability and accessibility of hand-washing facilities and supplies of hand-washing agents in the outpatient department (OPD) complex of a tertiary care teaching hospital. METHODOLOGY A checklist containing 13 variables was prepared and all rooms of direct patie...

We evaluated the microbial contamination of 17 types of vegetable and 10 types of fruit after 30-s washing with tap water with and without subsequent disinfection by 10-min immersion in 0.01% (100 ppm) sodium hypochlorite. The mean microbial contamination level of 9 types of leafy vegetable was 2.8 x 10(5) colony-forming units (CFU)/g after washing with water and 3.4 x 10(4) CFU/g after washing...

BACKGROUND More than 95% of neonatal deaths occur in developing countries, approximately 50% at home. Few data are available on the impact of hand-washing practices by birth attendants or caretakers on neonatal mortality. OBJECTIVE To evaluate the relationship between birth attendant and maternal hand-washing practices and neonatal mortality in rural Nepal. DESIGN Observational prospective ...

Abstract The roller brush cleaning path of the gantry reciprocating automatic car washing machine is key to determining quality wash. For issue that traditional method cannot accurately and reliably calculate path, a rolling planning scheme combined with fractional differential algorithm proposed. By analysing working form appearance characteristics car, multi-view detection system designed, im...

lactide was synthesized by reverse polymerization of low molecular weight poly(lactic acid) with two different molecular weights:1500 and 2500. two different lactide purification processes such as: recrystallization in ethyl acetate and washing the crude lactide with ether before recrystallization in ethyl acetate were evaluated. it has been demonstrated that increasing the molecular weight of ...

Insecticide application is the most common method of insect control in agriculture. Efficiency washing treatments reduction insecticide (chlorpyrifos-methyl and lambda-cyhalothrin) residues from grapes were investigated this study. The trial was established a Sultana seedless vineyard Sar?göl District, Manisa Province, Turkey 2020. Method verification performed with recovery, limit quantificati...
