Let us call a property that is essentially dispositional a potency. David Armstrong thinks that potencies do not exist. All sparse properties are essentially categorical, where sparse properties are the explanatory properties of the type science seeks to discover. An alternative view, but not the only one, is that all sparse properties are potencies or supervene upon them. In this paper I shall...

In our recent paper,‘’) we called attention to some of the points raised by Wlupple and by Zeise, Crouch, and Wilson. Our interest in this subject developed as we began analyzing our database of animal carcinogenesis bioas~ays.(*~~)In our analyses, we used as a measure of carcinogenic potency, the TD,,, defined as the dose rate (in mg/kg/body wt/day) which, if administered chronically for a sta...

foot-and-mouth disease is an important viral disease of cloven-hoofed animals. inactivated whole particle virus vaccines are still widely used in prophylactic vaccination campaigns. the choice of adjuvant is a very important factor in enhancing immune responses and the efficacy of inactivated vaccines. montanide isa 61 vg is a new ready-to-use mineral oil-based adjuvant developed by seppic inc....

In a working class industrial area of Karachi hundred consecutive Pathans presenting to a family physician with potency disorder were examined. After exclusion of those with structural or drug related conditions, a structured proforma was introduced. Their presentation, associated symptoms and background pointed to masked depression and lack of sex education. Symptoms of anxiety were noticed in...

‎In this paper we give an upper bound for Noetherian dimension of all injective modules with Krull dimension on arbitrary rings‎. ‎In particular‎, ‎we also give an upper bound for Noetherian dimension of all Artinian modules on Noetherian duo rings.

Atomization is an intricate operation involving unstable and complex networks with rupture fusion of liquid molecules. There are diverse details that typify the spray formation, which technique configuration atomization process, dimension structure nozzle, experimental parameters, etc. Ultimately, process generates fine sprays from bulk a liquid. Some examples we come across in our day-to-day l...

The Raman spectra of Ge–S glasses in the Ge-rich region from Ge 33% to 46% have been investigated in order to know the structural development of the network glasses. From the detailed curve fits, we have found that there is an unassigned peak at 410 cm 1 and it becomes larger with increasing Ge composition. To clarify the structural origin of the peak, we virtually constructed the atomic arrang...

 In this paper, a new homological dimension of modules, copresented dimension, is defined. We study some basic properties of this homological dimension. Some ring extensions are considered, too. For instance, we prove that if $Sgeq R$ is a finite normalizing extension and $S_R$ is a projective module, then for each right $S$-module $M_S$, the copresented dimension of $M_S$ does not exceed the c...
