Worm en español

The new IW Mk2 worm gear operators have been designed to suit isolating duty motorised applications. The gearboxes include low lead angle gearing designed to be inherently self-locking, and offer an increased torque output per size compared to the previous IW range. IW Mk2 worm gear operators are quarter-turn devices intended for the operation of ball, plug and butterfly valves. IW14 to 17 torque range from , Nm to , Nm , ft lbs to , ft lbs.

A parasitic worm that causes billions of dollars of crop damage annually, could actually make plants more resilient in the face of disease, a new study finds. The parasites in question — nematodes also known as roundworms — produce a pheromone called ascaroside, which they use for communication between one another.

The team of international researchers had carried out previous studies that showed that in the presence of this compound, plants increase their immune response — most likely as a hardwired defence mechanism against the parasites, which typically infest the soil around their roots. In their recent Journal of Phytopathology study , the researchers isolated the ascaroside compound, and applied it to test plants of four major crops: soybeans, rice, wheat, and maize.

When they then infected those treated plants with a range of fungal, bacterial, and other plant diseases, they discovered that overall, these plants were more capable of fighting off threats. In soybean plants, ascaroside helped the plants ward off the damaging Mosaic Virus, as well as strains of bacterial blight.

Treated wheat plants were more resistant to two prominent types of fungus that affect crops globally. The discovery is part of a new trend in agricultural research to find ways of developing crops that have in-built resistance to pests — including, for instance, the breeding of genetically-resistant plants.

This parasitic worm might hold the key to sustainable pesticides. Nematode worms cause billions of dollars of agricultural damage each year. But they produce a compound that conversely could actually protect crops against disease.

Fight against the screw-worm infestation. Economic and Social Council , 2nd sess. Welcomes the prompt response by IFAD in initiating the regional pilot biological control programme for the New World screw-worm in North Africa and by FAO in establishing the Screw-worm Emergency Centre for North Africa for the execution of the pilot and subsequent programmes, the technical support extended by IAEA and the financial support extended by the African Development Bank and UNDP; requests the Governments and organizations concerned to monitor the situation closely and to take further measures to bring about the complete eradication of the screw-worm in Africa; urges funding agencies and the donor community to support the eradication programme to ensure its successful completion.

The Ice Worm is an aggressive leviathan class fauna species that burrows beneath the surface of the ice. They appear to be ambush predators, drawn towards vibrations above them. Ice Worms are exclusively subterranean creatures and do not swim. Ice Worms can be avoided through the use of a Thumper. The Ice Worm has a very long body, the top side of which is completely covered by a thick segmented exoskeleton. Beneath these plates are another set of triangular plates that stick out horizontally, each with a backwards facing spike.
