A practical and long-term usable air-cleaner based on the synergy of photocatalysis and plasma treatments has been developed. A field test of the air-cleaner was carried out in an office smoking room. The results were compared to previously reported laboratory test results. Even after a treatment of 12,000 cigarettes-worth of tobacco smoke, the air-cleaner maintained high-level air-purification...

Advances in vehicle design and fuel quality mean cars can be made cleaner and more efficient. Lower emissions of carbon monoxide (CO), nitrogen oxides (NOx), sulphur dioxide (SO2), particles (including the fine dust and soot PM10) and hydrocarbons (HCs) also known as volatile organic compounds (VOCs) will lead to better urban air quality and less summertime smog. Lower emissions of carbon dioxi...

Lung tumours of non small cell pathology were cultured by clonogenic assay in several media. Culture was successful in spleen conditioned medium, but only 57% grew and low plating efficiencies (PE) meant that only 23% of the original number produced significant drug results. Comparison of rat erythrocyte lysate (REL) medium with serum free defined medium (HITES) and HITES+10% FBS demonstrated c...

gobies, which obtain most of their food via cleaning. Some obligate cleaners, such as L. bicolor and L. phthirophagus, mostly eat fish mucus and so are not considered as cooperative as the rest. But even the supposedly very cooperative ones, like L. dimidiatus, will eat mucus when they can get it. Most cleaner fish, however, are facultative cleaners which means they do not rely solely on cleani...

introduction: cleaner productions in textile industry is achieved by reducing water and chemicals’ consumption, saving energy, reducing production of air pollution and solid wastes, reducing toxicity and noise pollution through many solutions. the purpose of the present research was to apply strengths, weaknesses, opportunities, threats (swot) and quality systems planning matrix (qspm) techniqu...

this study was conducted to identify emission characteristics of certain hazardous substancescontained in the plastic of used home electrical and electronic appliances keeping in view compliance with therestriction of hazardous substances (rohs) directive and to estimate the possibility of safe recyclingpractices. according to the results, the concentration of cadmium, lead, mercury and chromiu...

Cleaner Production (CP) is a preventive environmental management approach aimed at reducing pollution at source. Despite the success stories, the literature indicates barriers that hamper the implementation and dissemination of CP in companies. Among these barriers are the lacks of detailed and systematized information on practices that generate results and can be applied in CP implementation p...

Images are increasingly used for AI-based diagnosis and analysis of many diseases like cervical cancer, mouth glucose from retina etc. In cases, data collection is done by specialised camera modules which capture images affected areas. As with any other sources data, this process also error-prone may contain unwanted objects regions that require cleaning removing them. Outliers in these kinds d...
