background disclosure of hiv is important for improving self-care behaviors, psychological well-being, commitment to the treatment, and reducing risk of transmission. one of the major benefits of disclosure is social support, which is an essential resource for effective coping with hiv infection. however, receiving any social support requires disclosing of hiv status. objectives this study aime...

let (m,g ) be a compact immersed hypersurface of (rn+1,) , λ1 the first nonzeroeigenvalue, α the mean curvature, ρ the support function, a the shape operator, vol (m ) the volume of m,and s the scalar curvature of m. in this paper, we established some eigenvalue inequalities and proved theabove.1) 1 2 2 2 2m ma dv dvn∫ ρ ≥ ∫ α ρ ,2)( )2 2 1 2m 1 mdv s dvn nα ρ ≥ ρ∫ − ∫ ,3) if the scalar curvatu...

the present study was undertaken to investigate the role of banana extract (be) on synchronous plantlet formation from seeds of dendrobium lituiflorum lindl. the seedlings formed on modified knudson c (kc) medium supplemented with 20% (v/v) be had significantly high fresh and dry weights. morphologically uniform plantlets with elongated leaves and well developed roots were formed on kc medium w...

utilizing the gathered failure data and failure interval data from tabas coal mine in two years, this paper discusses the reliability of powered supports. the data sets were investigated using statistical procedures and in two levels: the existence of trend and serial correlation. the results show that the powered supports follow the gamma reliability function. the reliability of the machine de...

background: cancer diagnosis is an important event in an individual’s life which has considerable outcomes and implications for patient and his/her family. meanwhile, receiving assistance and support from family and friends has a significant impact on patients to help them to cope with disease-related stress and its treatment. this study aimed to assess the received social support and its corre...

Wilson’s disease (WD) or hepato-lenticular degeneration is a rare autosomal-recessive disorder. A prevalence rate of 30 cases per million and a birth incidence rate of one per 30,000 to 40,000 are often quoted. In 40 to 50% of individuals with WD, hepatic dysfunction is the initial clinical manifestation. With the exception of liver transplantation, treatment of WD is only palliative and intend...

the engineers can frequently encounter with the situation to select the optimum option among the alternatives related with tunneling operations. the optimum choice can be selected by the experienced engineers taking into consideration their judgment and intuition. however, decision-making methods can offer to the engineers to support their optimum selection for a particular application in a sci...

support vector regression (svr) solves regression problems based on the concept of support vector machine (svm). in this paper, a new model of svr with probabilistic constraints is proposed that any of output data and bias are considered the random variables with uniform probability functions. using the new proposed method, the optimal hyperplane regression can be obtained by solving a quadrati...
