Plastic debris into the environment is a growing threat for ecosystems and human health. The seafood sector particularly concerned because it generates plastic losses can be endangered by contamination. Life cycle assessment (LCA) does not properly consider related impacts, which problem in order to find relevant mitigation strategies without burden shifting. This work proposes methodology quan...

Marine fisheries provide livelihood and nutritional security to the fishermen households in coastal states of our country Ramanathapuram district is an important Tamil Nadu terms marine fish landings as well raft-gears employed. The analysis economic performance fishing methods very for formulating any management measure. Hence, study on was carried out. In mechanized, motorized non-mechanized ...

The French fishing industry is becoming increasingly environmentally aware and likely to adopt more sustainable gears. As a result, fishers are showing growing interest in fish pots. This experiment aimed develop pot concept specifically based on target species behavior coastal waters. First, the consultation led with indicated black seabream as main of interest. Then, pot’s characteristics wer...

Centrifugal compressor and turbine manufacturers are building machines that operate at increasingly higher speeds to reduce the size and cost of their equipment. Helical gears are commonly used to step down the speed of these machines to match nominal motor and generator speeds. The demand for higher compressor and turbine speeds has resulted in an increase in the maximum pitch line velocities ...

The ecological effects of seabed-penetrating fishing gears depend, in part, on the seabed penetration (P) gear. We present a gear impact tool that utilizes published data to provide estimated P globally utilized different sediments and their resulting biological communities. As correlates with depletion (d) benthic fauna caused by gears, we use calculate d, which can be used estimate relative s...

There were severe pitting corrosions on the surface of transmission gears in diesels. The cause of metal fatigue pitting of gear surface is analyzed in the paper, which based on the contact fatigue experiment of 18Cr2Ni4WA carburizing and quenching gears used in the diesel engine. Causes of pitting on harden tooth surface are studied from three aspects: gear surface residual stress field, oil f...
