this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...

This paper describes the first hand experiences of the electronic point of care (ePOC) project team and the project management and research and development issues that emerged over the course of a collaborative 3 year eHealth project. The paper highlights that despite the best of intentions by project managers, researchers and developers, a technologically innovative concept is no guarantee of ...

background: the effects of aqueous extract of fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in wistar rats. methods: in total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (a-e): animals in group a received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in group...

The islands of the Caribbean are a particularly interesting geographical region to examine the dynamic relationship between past human communities and sudden environmental change. This chapter examines how past peoples, living on the islands in the Caribbean Sea, were vulnerable to a number of environmental threats. The focus of this chapter is the impact of floods, droughts, and wind shear cre...

Governments and donors are investing in climate compatible development in order to reduce climate and development vulnerabilities. However, the rate at which climate compatible development is being operationalised has outpaced academic enquiry into the concept. Interventions aiming to achieve climate compatible development "wins" (for development, mitigation, adaptation) can also create negativ...

Roads are a major cause of habitat fragmentation that can negatively affect many mammal populations. Mitigation measures such as crossing structures are a proposed method to reduce the negative effects of roads on wildlife, but the best methods for determining where such structures should be implemented, and how their effects might differ between species in mammal communities is largely unknown...

this research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester university students majoring in tefl and english translation fields based on vygotsky’s sociocultural theory in general and the notion of “zone of proximal development” in particular. to that end, this study relied on a pre-posttest experimental...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....
