In this paper, the generic intersection theory for difference varieties is presented. Precisely, the intersection of an irreducible difference variety of dimension d > 0 and order h with a generic difference hypersurface of order s is shown to be an irreducible difference variety of dimension d−1 and order h+s. Based on the intersection theory, the difference Chow form for an irreducible differ...

introduction: the antibacterial effects of calcium hydroxide (ch), mineral trioxide aggregate (mta), and calcium enriched mixture (cem) cement against various spp. of microorganisms were assessed in-vitro using agar diffusion test. materials and methods: a base layer of petri plates was made using muller-hinton agar. four cavities were made in agar and filled with freshly mixed materials after ...

In this study, we consider two different inequivalent formulations of the logistic difference equation $x_{n+1}= beta x_n(1- x_n), n=0,1,..., $ where $x_n$ is a sequence of fuzzy numbers and $beta$ is a positive fuzzy number. The major contribution of this paper is to study the existence, uniqueness and global behavior of the solutions for two corresponding equations, using the concept of Huku...

The maximum redox potential difference between the NAD+/NADH couple and the succinate/fumarate couple generated during ATP-energized reduction of NAD+ by succinate in submitochondrial particles was measured, together with the electrochemical potential difference for protons (delta mu approximately H+). The presence of cyanide, the time-independence of the redox potential difference and the irre...

Objective(s): To evaluate the role of Tc-99m TRODAT-1 Single Photon Emission Computed Tomography (SPECT) in Parkinson’s Disease (PD) by assessing the correlation of clinical disease severity, disease duration and age at onset of disease with specific uptake ratio of Tc-99m TRODAT-1 in striatum.Methods: The study included 63 patients in age range of 40-72 years with clinical diagnosis of PD and ...

Helicobacter pylori is thought to be related to atherosclerosis and aneurysm development. We aimed to detect virulance factors of H. pylori and examine the potential etiopathogenetic relationship between aortic aneurysm and H. pylori, 58 abdominal aortic aneurysm (AAA) and 38 ascending aortic aneurysm (AsAA) cases and 57 Healty control group (HCG) were included. We investigated H. pylori IgG by...

Given a conjugation C on separable complex Hilbert space H, bounded linear operator T H is said to be C-skew symmetric if CTC = -T*. This paper describes the maps, algebra of all operators acting that preserve difference for every H.

AIMS To investigate the pharmacokinetics and pharmacodynamics of epirubicin and paclitaxel in combination, as well as the effects of paclitaxel and its vehicle Cremophor EL on epirubicin metabolism. METHODS Twenty-seven female patients with metastatic breast cancer received epirubicin 90 mg m-2 i.v. followed 15 min or 30 h later by a 3 h i.v. infusion of paclitaxel 175, 200 and 225 mg m-2. Pl...

It has been demonstrated that by the mixed cultures in the presence of PHA the combination of those cells whose H-2 antigens differ from each other shows a higher rate and more significant difference of blastformation than in the combination where non-H-2 antigens differ (Table 1). The blastformation observable in the combinations where non-H-2 histocompatibility antigens or sex.linked antigens...
