Recently, power quality (PQ) has because a significant issue for both power supplies and customers. Researchers in all developed countries know that power quality is one of the factors of losses in the network. Increasing power electronic equipment changes current waveform in distribution networks and this can cause many problems in networks. Distortion of voltage waveforms results in the appea...

A wide range of technology is available for application of entomopathogenic nematodes including various irrigation systems and spray equipment. The choice of application equipment, and manner in which the nematodes are applied, can have substantial impact on pest control eYcacy. For example, nozzle or pumping system types are some of the parameters that can aVect nematode performance following ...

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

In the current sport-equipment industry, equipment evaluation and/or optimization are mainly done through pure mechanical procedures. It is known that any change of performance environment would cause one to adapt certain aspects of his or her movements to the changed environment. Variation of sport-equipment is counted as an environment change for human performance. Yet, the equipment-induced ...

The setting up and priming of an intravenous infusion is a common nursing procedure. However, it is associated with certain complications, for example infection. This article describes a step-by-step guide to the equipment required, correct preparation of the patient and the procedure. It also provides readers with calculation of drip-rate formulae.

The Initial Problem Anyone who’s been paying attention knows that the governments are turning “green” – meaning they are banning “hazardous” substances. The European Union (EU) took the lead in this endeavor with a directive, “restriction on the use of certain hazardous substances in electrical and electronic equipment,” or simply. “RoHS” This directive (with some exceptions) bans six substance...
