objective: in developing countries, nutritional deficiency of essential trace elements is a common health problem, particularly among pregnant women because of increased requirements of various nutrients. accordingly, this study was initiated to compare trace elements status in women with or without pre-eclampsia. materials and methods: in this study, serum trace elements including zinc (zn), s...

background: the objective of this study is to optimize the effective dose of heparin and ligustrazine hydrochloride injection (lhi) for drug combination. materials and methods: the animal clinical study of lhi was performed by the rat’s model of induced arteriovenous shunt thrombosis. experimental animals were grouped into several groups and separately treated with both lhi (20, 40, 80 mg/kg, i...

background: designing intervention based on health-care settings resources and patient acceptability is potentially important in the prevention of high blood pressure (bp) and other risk factors of cardiovascular disease. to explain a multicenter randomized controlled trial that is designed to examine the effects of the multicomponent lifestyle modification program on bp. materials and methods:...

Competition law in many countries prohibits …rms from making false claims about product quality or performance to potential buyers and also requires that the truth of speci…c claims be supported by adequate prior testing. This paper explores the di¤erences between these two policies and asks, among other questions, whether a policy of mandatory prior substantiation has any incremental e¤ect if ...

We describe a method that performs automated recognition of individual laetherback turtles within a large nesting population. With only minimal preprocessing required of the user, we prove able to produce unsupervised matching results. The matching is based on the ScaleInvariant Feature Transform by Lowe. A strict condition posed by biologists reads that matches should not be missed (no false n...

Emerging peer to peer (P2P) applications have a requirement for decentralised access control. Computational trust systems address this, achieving security through collaboration. This paper surveys current work on overlay networks, trust and identity certification. Our focus is on the particular problem of distributing evidence for use in trust-based security decisions. We present a system we ha...
