motivated by the recent study on categorical properties of latticevalued topology, the paper considers a generalization of the notion of topological system introduced by s. vickers, providing an algebraic and a coalgebraic category of the new structures. as a result, the nature of the category   topsys   of s. vickers gets clari ed, and a metatheorem is stated, claiming that (latticevalu...

background: knowing the pattern of carbon monoxide (co) poisoning in each region is vital for enhanced health planning. this study was designed to evaluate the epidemiologic pattern of unintentional acute co poisoning in major cities of fars province, southwest of iran.  methods: this one-year cross-sectional study was carried out on unintentional co poisoning incidents in fars province, iran, ...

The Rycroft-Malone paper states that co-production relies on ‘authentic’ collaboration as a context for action. Our commentary supports and extends this assertion. We suggest that ‘authentic’ co-production involves processes where participants can ‘see’ the difference that they have made within the project and beyond. We provide examples including: the use of design in health projects which see...

A graph G is a Zm-well-covered graph if |I1| ≡ |I2| (modm) for all maximal independent sets I1 and I2 in V (G) [3]. The recognition problem of Zm-well-covered graphs is a Co-NP-Complete problem. We give a characterization of Zm-well-covered graphs for chordal, simplicial and circular arc graphs. c © 2001 Elsevier Science B.V. All rights reserved.

Value co-creation process as a mutual interaction between individuals is a key issue across the management network. Recently, studies have placed a special emphasis on people’s interaction in order to accomplish value co-creation. Given that the process of experience exchange enables us to identify our resources in transactional processes and make collaboration to achieve common values, the pur...

hepatitis b virus (hbv) is the most prevalent viral infection and is among the leading causes of human liver diseases. nearly 360 millions of people are world widely infected with prolonged forms of hepatitis b including active and inactive chronic forms. chronic hepatitis b (chb) is associated with cirrhosis and hepatocellular carcinoma (hcc) in patients suffering from congenital and/or acquir...

heavy metals removal from polluted wastewater is one of the major concerns due to their harmful effectson human health and the environment. the aim of this study is to absorb cu2+ and co+2 ions from wastewater by means of a synthesized magnetite bentonite nono - adsorbent. initially, nano- adsorbent was produced by coprecipitation techniques. then, the resultant material was analyzed and evalua...
