A characterization of the quotient proximity is given. It is used to find necessary and sufficient conditions for every proximity map on a space to be a topological quotient map. It is shown that a separated proximity space is compact iff every /7-map on X with separated range is a proximity quotient map. Introduction. In 1959 Katetov [3] introduced proximity quotient maps. They have since been...

LPG (Liquefied Petroleum Gas) is a petroleum derived, colorless gas, typically comprised of mainly propane, butane, or a combination of these two constituents. LPG fuel for vehicles is actually a mixture of various hydrocarbons which are gases at atmospheric pressure and temperature but which liquefy at higher pressures like less than 200 psi. LPG is a natural derivative of both natural gas and...

Lipophosphoglycan (LPG) is the predominant surface glycoconjugate of Leishmania promastigotes and plays several roles in the infectious cycle of this protozoan parasite. The salient feature of LPG is the presence of 15-30 copies of a disaccharide-phosphate repeating unit Gal(beta1,4)Man(alpha1-PO4), which is also found on many other secreted molecules (secretory acid phosphatase, phosphoglycan,...

Both lipoprotein glomerulopathy (LPG) and fibrillary glomerulonephritis (FGN) are rare causes of end-stage renal disease (ESRD), and the literature concerning the outcome of kidney transplant in patients with LPG or FGN is scarce. We report a patient who suffered from ESRD with coexisting FGN and LPG and received deceased kidney transplant >10 years ago did not reveal any clinical features of d...

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...

Surface glycoconjugates play important roles in the infectious cycle of Leishmania major, including the abundant lipophosphoglycan (LPG) implicated in parasite survival in the sand fly vector and the initial stages of establishment in the mammalian host macrophage. We describe a system for inducible expression of LPG, applying a novel protein-based system that allows controlled degradation of a...

In order to analyze the changing rules of temperature and pressure of the gas-liquid coupled field of LPG (Liquefied Petroleum Gas) tank under fire, the application of the wavelet finite element method on it is studied in depth. First, the research achievements of thermodynamics response of the LPG tank under fire and the wavelet finite element theory is summarized. Second the temperature-press...

We prove that a space is quotient π-image of a locally separable metric space if and only if it has a πand double cs∗cover. We also investigate quotient π-s-images of locally separable metric spaces.

We consider a version of the AdSd+1/CFTd correspondence, in which the bulk space is taken to be the quotient manifold AdSd+1/Γ with a fairly generic discrete group Γ acting isometrically on AdSd+1. We address some geometrical issues concerning the holographic principle and the UV/IR relations. It is shown that certain singular structures on the quotient boundary S/Γ can affect the underlying ph...
