Bioplastics have proven to be a viable substitute for plastics in some sectors, although their use construction is still limited. The sector currently uses 23% of the world’s plastic production, both materials themselves and packaging protection. A considerable part not recycled dispersed into environment or ends up landfills. In response environmental problems caused by oil-based pollution, de...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
In today’s society, consumers’ food needs can be satisfied by catering e-commerce platforms. However, the plastic pollution of tableware and packaging caused a large number orders every day has always been an unsolved environmental problem. (1) Background: At present, China’s three largest platforms, Meituan, Eleme Baidu, receive 20 million takeout daily consume about 60 products. Plastic will ...
Helicity was calculated in Hurricane Bonnie (1998) using tropospheric-deep dropsonde soundings from the NASA Convection and Moisture Experiment. Large helicity existed downshear of the storm center with respect to the ambient vertical wind shear. It was associated with veering, semicircular hodographs created by strong, vortex-scale, radial-vertical flow induced by the shear. The most extreme v...
Plastics have been used extensively in both food and water packaging because of their inherent properties such as low bulk densities and inertness that make them convenient carrier materials and low risk contaminants. Plastic bottles and sachets used to package iced water that is sold to people in transit points and in moving vehicles have become widespread in the sub-region. However, the packa...
The excessive use of plastic in our society is causing a massive accumulation, since it non-biodegradable product and with still poor recycling rates. This effect can be observed the seas, which more waste are accumulating. present work critical review, based on all currently available literature, that reports environmental status marine pollution, especially microplastic Spain. three Spanish w...
Plastic pollution on land and in oceans is currently a pressing environmental issue. The accumulation of waste has caused severe, irreversible impacts consequences marine life, ecosystems, the environment due to lack good collection, treatment, management systems. Limited resources infrastructure constantly challenge Southeast Asia. Therefore, we will examine current plastic situation issues As...
nowadays, with population growth in urban areas, providing safe water and health is considered basic needs of human, alongside the various pollutants due to urban activities, agriculture and industrial areas on adjacent ranges into urban water resources around the environment is such that study necessary to prevent the pollution of water resources and identification of pollution sources shows. ...
• Circular economy is viewed as central to reduce plastic pollution. Link between circular and micro(nano)plastic contamination seldom made. Some recycling can lead increased with micro(nano)plastics. Extended producer responsibility be important for sustainable production. the most promising path a more use of plastic. It aims at reducing consumption resources by keeping materials within value...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
