In response to 9/11 and the increasing concerns over chemical sector security, Congress gave the Department of Homeland Security (DHS) the authority to regulate the safety and security of U.S. chemical facilities. In April of 2007, DHS passed the interim final rule called the Chemical Facility Anti-Terrorism Standards (CFATS) in order to secure the U.S. chemical infrastructure. Unfortunately, t...

Massive adoptions of combined heat and power (CHP) units necessitate the coordinated operation system district heating (DHS). Exploiting reconfigurable property networks (DHNs) provides a potentially cost-effective solution to enhance flexibility by readjusting configuration for supply, which has not been addressed in literature. To address this issue, unit commitment considering electricity ne...

PURPOSE We aimed to evaluate and compare the clinical and functional outcomes of dynamic hip screw (DHS) and proximal femoral nail antirotation (PFNA) treatment of AO type 1 intertrochanteric fractures in elderly patients. MATERIALS AND METHODS We retrospectively reviewed 194 consecutive patients with type A1 intertrochanteric femoral fractures who were treated with DHS (n=113) or PFNA (n=81)...

After glycosylphosphatidylinositols (GPIs) are added to GPI proteins of Saccharomyces cerevisiae, a fatty acid of the diacylglycerol moiety is exchanged for a C(26:0) fatty acid through the subsequent actions of Per1 and Gup1. In most GPI anchors this modified diacylglycerol-based anchor is subsequently transformed into a ceramide-containing anchor, a reaction which requires Cwh43. Here we show...

DNA replication origins strikingly differ between eukaryotic species and cell types. Origins are localized and can be highly efficient in budding yeast, are randomly located in early fly and frog embryos, which do not transcribe their genomes, and are clustered in broad (10-100 kb) non-transcribed zones, frequently abutting transcribed genes, in mammalian cells. Nonetheless, in all cases, origi...

A series of fatty acid conjugates of trans-3,4-dihydroxy-1-selenolane (DHS) were synthesized by reacting DHS with appropriate acid chlorides. The obtained monoesters were evaluated for their antioxidant capacities by the lipid peroxidation assay using a lecithin/cholesterol liposome as a model system. The observed antioxidant capacities against accumulation of the lipid hydroperoxide (LOOH) inc...

District heating systems (DHS) are driven by the heat demands of their consumers, with higher giving a load on production. While human-dependent, they contain diurnal behaviors and weather dependencies. The periods high causing peak loads production, which is operationally costly. This especially true for pumps, solution DHS to include green energy, as cost depends directly needed temperature. ...

Este artigo é um recorte da pesquisa de Mestrado encaminhada no ProfEPT. A pesquisa, ensino médio integrado do IFSul Passo Fundo, busca aferir percepções dos alunos sobre Direitos Humanos – DHs, propondo produto na concepção educação integral. O estudo uma pesquisa-ação, que iniciou pela fundamentação teórica. instrumento coleta foi questionário e, pelas respostas, serão selecionados para aplic...

The 1993-94 Bangladesh Demographic and Health Survey (DHS) reported substantial declines in vital rates, especially the fertility rate, which needed confirmation. The demographic database of the International Center for Diarrheal Disease Research, Bangladesh (ICDDR,B) contains the birth and death records for 200,000 people whose households have been visited every 2 weeks since 1966. In additi...
