BACKGROUND Visual impairment (VI) affects physical, psychological, and emotional well-being, and social life as well. The purpose of this exploratory study was to assess the psycho-social impact of VI on health-related quality of life (HRQoL) among nursing home residents. METHODS This cross-sectional study involved 272 residents of 60 years or older residing in seven nursing homes of the Kath...

this study investigates the effects of inputs on production risk of sugar beet  farmers in fars province. the study carried out in 1996. the needed data  were collected by completing questionnaire  from 120 farmers in fars selected through a two-stage cluster sampling survey. the results showed that pesticide, animal fertilizer, seed and irrigation have significant effects on production changes...

this study is made to find out the variations of the outer body morphology of luciobarbus mystaceus (pallas, 1814) belonging cyprinidae family that lived in tigris river system between january 2015 and december 2015 with geometric morphometric methods depending on gender, age and season. after being caught with fishnet having different meshes and brought to the laboratory, in total 58 (21♀♀, 37...

In addition to essential nutrients, human milk contains several classes of bioactive factors such as enzymes, hormones, and growth factors, many of which are implicated in infantile growth and development. Secretory carbonic anhydrase isoenzyme VI (CA VI) has been identified earlier as an essential component of mammalian saliva, and we demonstrate here by using biochemical and immunohistochemic...

We give a tight bound on randomized online coloring of hypergraphs. The bound holds even if the algorithm knows the hypergraph in advance (but not the ordering in which it is presented). More specifically, we show that for any n and k, there is a 2colorable k-uniform hypergraph on n vertices for which any randomized online coloring uses Ω(n/k) colors in expectation. 1 Online Hypergraph Coloring...

Type VI collagen has recently been shown to be an important component of connective tissue. Double label immunofluorescence procedures were used to immunolocalize type VI collagen in normal and rheumatoid synovium and its distribution was compared with that of fibronectin. In normal synovium type VI collagen is expressed in the synovial membrane but not in the interstitium of the villus. In rhe...

In this paper, we show that for any BL-general L-fuzzy automaton (BL-GLFA) there exists a complete deterministic accessible reduced BL-general L-fuzzy automaton that recognizing the behavior of the BL-GLFA. Also, we prove that for any finite realization β, there exists a minimal complete deterministic BL-GLFA recognizing β. We prove any complete deterministic accessible reduced BL-GLFA is a min...
