Locally partial-ordered spaces (local po-spaces) have been used to model concurrent systems. We provide equivalences for these spaces by constructing a model category containing the category of local po-spaces. We show the category of simplicial presheaves on local po-spaces can be given Jardine's model structure, in which we identify the weak equivalences between local po-spaces. In the proces...

UNLABELLED The study was performed to compare the (18)F-labeled nitroimidazole compound fluoroazomycin arabinoside ((18)F-FAZA) with the standard hypoxia tracer fluoromisonidazole ((18)F-FMISO) in detection of tumor tissue hypoxia and to verify the oxygenation dependency of (18)F-FAZA uptake. METHODS Biodistribution of (18)F-FAZA was studied at various time points in EMT6 tumor-bearing BALB/c...

-Phenamiphos interacted with homoionic montmoriUonites of Ca 2+, Mn 2+, Co 2+, and Ni 2+ to form interlayer complexes having basal spacings of about 16.5/~. In the infrared spectra, the v-PO bands were displaced towards lower frequencies suggesting that this group interacted with the exchange cations. Moreover, a small shoulder at 1600 cm -~ indicated the partial protonation of the phenamiphos....

Let G = ∗ i=1 Gi and let φ be a symmetric endomorphism of G. If φ is a monomorphism or if G is a finitely generated residually finite group, then the fixed subgroup Fix(φ) = {g ∈ G : φ(g) = g} of φ has Kurosh rank at most n.

r is called commuting regular ring (resp. semigroup) if for each x,y $in$ r thereexists a $in$ r such that xy = yxayx. in this paper, we introduce the concept of commuting$pi$-regular rings (resp. semigroups) and study various properties of them.

The influence of feeding hydrogenated fat (HF) or refined peanut oil (PO) diet and regular swimming exercise on hepatic and skeletal muscle antioxidant enzymes i.e., catalase ,and glutathione peroxidase (GPX) as well as tissue lipid peroxidation was investigated in male Wistar rats. Two groups of rats were fed diet with HF or PO as the only fat source. Both the groups were further divided into ...

Reconstructing sociosexual variables such as mating system and social organization from fragmentary fossils and other sources of data remains a major challenge in understanding the evolution of behavioral and morphological diversity within the primate order. Often, a particular mating system can lead to the evolution of novel behavior (e.g., ‘‘competitive’’ paternal care in tamarins; Garber, 19...

In this paper, we determine, in terms of the Sullivan models, rational evaluation subgroups inclusion $ \mathbb{C} P(n)\hookrightarrow P(n+k) between complex projective spaces and, more generally, G $-sequence homotopy monomorphism \iota: X\hookrightarrow Y simply connected formal homogeneous for which \pi_{\ast}(Y)\otimes \mathbb{Q}$ is finite dimensional.
