Abstract The use of chemical methods weed control is an effective means control. However, the large amounts herbicides leads to environmental pollution, contaminates food, and adversely affects health people working with herbicides. safest method mechanically remove weeds by pulling rooted out soil or cutting driving under soil. Robots pneumatic, hydraulic, electrical systems cutters. Electrica...
The increase in gravitational wave (GW) events has allowed receiving strong lensing image pairs of GWs. However, the effect (diffraction and interference) due to microlens field contaminates parameter estimation pair, which may lead a misjudgment signals. To quantify influence field, researchers need large sample statistical research. Nevertheless, oscillation characteristic, Fresnel-Kirchhoff ...
Commercial composting of the mechanically separated organic fraction municipal solid waste (MS-OFMSW) is employed to stabilize waste. Its feasibility linked process efficacy and compost stability. Threshold values for stability are imposed by regulatory frameworks. Limited reuse options exist this material often due presence pollutants. The optimisation required reach in a viable timeframe. We ...
The residents of West Waru Village, Pamekasan, are renowned for their high numbers cows, leading to a steadily increasing amount cow dung that contaminates the environment. To combat this problem, we must find ways utilize manure. There is potential solution in form biogas generator technology, which can convert manure into energy. This research seeks develop and optimize its design order provi...
Banknotes are widely exchanged for goods and services worldwide. During its circulation, it can get contaminated by money counting machines, atmosphere, dust, soil, storage process or during usage. soiling level is considered the most predominant reason classifying notes as defective, so reduction should be first aim of developing more durable banknotes. Many countries begin to apply clean note...
An increasing number of human beings from developed countries are colonized by Escherichia coli strains producing colibactin, a genotoxin suspected to be associated with the development of colorectal cancers. Deoxynivalenol (DON) is the most prevalent mycotoxin that contaminates staple food-especially cereal products-in Europe and North America. This study investigates the effect of the food co...
Abstract Background and objectives: Air ionization (AI) may reduce the microbial content of the air 'and has bactericidal effects on some bacterial Strains, which is controversial. We conducted this study to evaluate the efficacy of Air ionizer in reducing the microbial content of air. Material and Methods: This experimental Study was carried out in Sadi Hospital of Isfahan. Two air ionizer wer...
introduction gastric emphysema or pneumatosis is a rare finding. early endoscopy and urgent laparotomy is advised in post trauma patients. case presentation a 29 year old man presented with blunt abdominal injury following a high-speed motorbike crash he complained of abdominal pain and abdomen was distended. ct abdomen revealed air in the gastric wall with disruption of gastric mucosa. he had ...
background and aims:nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. the purpose ...
backgrounds and aims: ammonia removal from air to prevent severe damage to the environment and living organisms is very important. biofiltration is an efficient, easy, cost-effective, and environmentally friendly process for degradation of ammonia from waste air. the aim of this study is to investigate the efficiency of biological filtration using a compost and scallop bed for ammonia removal. ...
