background: widespread use of the internet, lack of proper use and non-targeted searches, not only moves the students far from the main mission of the internet in the university but also will impact adversely on their academic status . the aim of this study was to determine the relationship between internet addiction with academic status and smoking in lorestan university of medical sciences, i...

in the present study, interactions between lead exposure with nitric oxide precursor (l-arginine) or nitric oxide synthase (nos) inhibitor (l-name) on naloxone-induced jumping and diarrhea in morphine-dependent mice were examined. chronic lead acetate (0.05%) exposure altered naloxone-induced jumping and diarrhea in mice. jumping was decreased after 7 days and was unchanged 14 and 28 days after...

maintaining dignity and respect is among patients’ most fundamental rights. the importance of patient dignity, the status quo, patients’ needs, and a shortage of survey studies in this area were the underlying incentives for conducting this study. this was a cross-sectional descriptive study in which data were collected through patient dignity inventory (pdi). the questionnaire was completed by...

conservation of biodiversity in protected areas will be more challenging if local communities are heavily dependent on them for various products and subsistence needs. this study estimated forest dependency and identified factors influencing dependency for households living around kasane forest reserve (kfr). data collected from 237 households were analyzed using logistic regression model. logi...

The Profile Hidden Markov Model (PHMM) can be poor at capturing dependency between observations because of the statistical assumptions it makes. To overcome this limitation, the dependency between residues in a multiple sequence alignment (MSA) which is the representative of a PHMM can be combined with the PHMM. Based on the fact that sequences appearing in the final MSA are written based on th...

As the XML functional dependency and multi-valued dependency impact on the normalization design of semi-structured data, definitions of XML functional dependency, XML multi-valued dependency, path dependency base and the minimal dependency set are given in this paper. Algorithms for minimal dependency set and membership with path expression based on the coexistence of XFD and XMVD are then prop...
