As part of a large-scale sero-epidemiological survey on visceral leishmaniasis (VL) carried out in Mymensingh district of Bangladesh, applicability of DAT was assessed at the level of a rural health setting in Trishal (upazila) subdistrict. Despite the relatively less optimal conditions encountered, 5854 inhabitants from 7 villages appendant to Trishal were(More)
Let E be a topological vector space and X be a non-empty subset of E. quasi-variational inequality (GQVI) problem is to find a pointˆy ∈ S(ˆ y) and a pointˆw ∈ T(ˆ y) such that Rê w, ˆ y − x ≤ 0 for all x ∈ S(ˆ y). We shall use Chowdhury and Tan's 1996 generalized version of Ky Fan's minimax inequality as a tool to obtain some general theorems on solutions(More)
In this paper, the authors prove some existence results of solutions for a new class of generalized bi-quasi-variational inequalities (GBQVI) for quasi-pseudo-monotone type I operators in non-compact settings in locally convex Hausdorff topological vector spaces. In obtaining these results on GBQVI for quasi-pseudo-monotone type I operators in non-compact(More)
Peginterferon alpha-2a and ribavirin combination therapy achieves a sustained virological response (SVR) in patients with chronic hepatitis C. Little is know about long-term durability of hepatitis C virus--Ribonucleic acid (HCV-RNA) negativity in patient treated with pegylated interferon and ribavirin therapy. Aim of this study was to evaluate the(More)
Suppose that E is a topological vector space and X is a non-empty subset of E. Let S : X → 2 X and T : X → 2 E * be two maps. Then the generalized quasi-variational inequality problem (GQVI) is to find a pointˆy ∈ S(ˆ y) and a pointˆw ∈ T(ˆ y) such that Rê w, ˆ y − x 0 for all x ∈ S(ˆ y). We shall use Chowdhury and Tan's generalized version [4] of Ky Fan's(More)
Existence theorems of generalized variational inequalities and generalized complementarity problems are obtained in topological vector spaces for demi operators which are upper hemicontinuous along line segments in a convex set X. Fixed point theorems are also given in Hilbert spaces for set-valued operators T which are upper hemicontinuous along line(More)
Chronic hepatitis B virus (HBV) is known to be the significant cause of Liver related morbidity and mortality, affecting 400 million people worldwide and a major public health problem in Bangladesh where carrier rates of HBV infection varies from 7.5 to 10%. In Bangladesh prevalence of asymptomatic HBV infection and incidentally detected HBsAg positive(More)
