We present a general approach for introducing specificity information into nonmonotonic theories. Historically, many approaches to nonmonotonic reasoning, including default logic, circumscription, and autoepistemic logic, do not provide an account of specificity, and so fail to enforce specificity among default sentences. In our approach, a default theory is initially given as a set of strict a...

Previous studies have demonstrated a stronger seroreactivity against some synthetic peptides responsible for inducing neutralizing antibodies in injecting drug users (IDU) compared to that of individuals sexually infected with HIV-1 (S), but the effectiveness in terms of the neutralizing ability of these antibodies has not been evaluated. Our objective was to study the humoral immune response o...

A microsporidium was isolated from larvae of Spodoptera litura (Fabricius) collected from Tamil Nadu, India. This microsporidian species is monomorphic, disporous and develops in direct contact with the cytoplasm of the host cell. The nuclear configuration of merogonic and sporogonic stages was diplokaryotic. The merogonic proliferative stage was unusual that normal development with 1, 2 and 4 ...

background: erysipelothrix rhusiopathiae (e. rhusiopathiae) is generally transmitted into the gastrointestinal tract of animals by the intake of contaminated food or water and causes great economic loss in agriculture worldwide. some of the erysipelothrix spp. are the causative agents of erysipeloid, which is an occupational infection in humans. the aim of the present study was to isolate e. rh...

Twenty Salmonella Gallinarum strains isolated from poultry were tested for Enterotoxigenicity activity using rabbit and chicken ligated intestine loop technique and the rabbit vascular permeability factor activity test. One ml of cell-free filtrate (CFF) of each isolate was injected into chicken ligated loops and rabbit ligated loops, one ml of whole cell culture(WCC) of each isolate was inject...

Background Protecting drinking water supplies from pathogens such as Cryptosporidium parvum is a major concern for water utilities worldwide. The sensitivity and specificity of current detection methods are largely determined by the effectiveness of the concentration and separation methods used. The purpose of this study is to develop micromixers able to specifically isolate and concentrate Cry...

Monoclonal antibodies to the RSN -2 isolate of human respiratory syncytial (RS) virus have been characterized with regard to their specificity for viral polypeptides and for different RS virus isolates. Five hybridoma antibodies recognized the phospho-protein VPP32 and the other recognized the matrix protein VPM27 . Evidence was obtained to support the view that VPP32 was associated with the nu...

The charge-transfer (CT) together with the polarization energy appears at second and higher orders in symmetry-adapted perturbation theory (SAPT). At present there is no theoretically compelling way of isolating the charge-transfer energy that is simultaneously basis-set independent and applicable for arbitrary intermolecular separation. We argue that the charge-transfer can be interpreted as a...
