PURPOSE To determine the potential risk of contamination of a trypan blue bottle (TB) after first use and after being stored under different temperature and humidity conditions, as well as to identify possible contamination factors, most frequently involved microorganisms and simultaneously evaluate bacteriostatic and bactericide properties of the dye. METHODS An experimental and prospective ...

growth inhibition of aspergillus fumigatus,aspergillus flavus and fusarum solani exposed to the essential oils including thyme, agastache and satureja were studied. disc diffusion method was used to evaluate the fungal growth inhibitory effects of the essential oils. minimal inhibitory concentration (mic) and minimal fungicidal concentration (mfc) of the oils were determined and compared with e...

Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...

we define minimal cn-dominating graph $mathbf {mcn}(g)$, commonality minimal cn-dominating graph $mathbf {cmcn}(g)$ and vertex minimal cn-dominating graph $mathbf {m_{v}cn}(g)$, characterizations are given for graph $g$ for which the newly defined graphs are connected. further serval new results are developed relating to these graphs.

This company produced intermediate compounds for the cosmetic and the pharmaceutical industries, including benzyl chloride and cyanide phenolacetic acid and 2,4,5 – trichlorophenol (TCP) – a toxic inflammable compound used as a bactericide and herbicide. It has been calculated that more than 1500 Kg of mixture went into the atmosphere including some Kg of pure 2,3,7,8 tetrachlorodibenzo-p-dioxi...

Development of materials with an antimicrobial activity is fundamental for different sectors, including medicine and health care, water and air treatment, and food packaging. Electrospinning is a versatile and economic technique that allows the incorporation of different natural, industrial, and clinical agents into a wide variety of polymers and blends in the form of micro/nanofibers. Furtherm...

In this paper, copper (II) citrate Cu3(C6H5O7)2 was successfully synthesised in an aqueous solution. The factors for the synthesis process such as temperature and molar ratio of reactants were investigated. structural, properties composition characteristics elements investigated evaluated by X-ray diffraction pattern (XRD), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive (EDX)...
