Abstract The aim was to explore potential differences on ghrelin plasm concentrations between efficient and inefficient lambs within a transient surge of secretion just before scheduled meal feeding. Six high- (256±19 g) six low-RFI (-242±19 Hampshire entire male (Age=168±2 d BW=63±5 kg) were taken out 25 individuals in 56-d GrowSafe SystemsÒ feeding trial. After 10-d adaptation once-daily ad-l...
Abstract Subsea water separation with pipe separators is crucial for ensuring efficient and environmentally responsible extraction of oil gas from the seabed. In this study, in a process called as “crude spiking,” two concentrations crude (e.g., 185 400 ppm) are added to Exxsol D60 mimic characteristics real mixtures multi-parallel separator. The separator performance water–oil bulk such effici...
LC3 - the mammalian homolog of Atg8 - was found as autophagosome membrane binding protein in mammals and widely used as an autophagosomal marker. LC3A, B and C show different expression patterns in each tissue. The aim of this study was to reveal the differences of expression patterns among LC3 families in mouse placenta under normal condition and nutrient starving condition. LC3A and B were hi...
Human peripheral blood lymphocytes that express T cell markers, when reacted for the cytochemical localization of lysosomal acid hydrolases, display two major patterns of staining, i.e., dot-like and scattered granular. Previous attempts to fractionate T cells according to surface markers have yielded populations of cells with heterogeneous patterns of cytochemical staining. In this study, peri...
چکیده مسئله فقر به خصوص فقر غذایی یکی از مسائل مهم جامعه است، آگاهی از میزان و عمق خط فقر تغذیهای اهمیت فراوانی برای حل این مسلئه دارد. لذا در این مطالعه حداقل معاش غذایی ( خط فقر غذایی) برای خانوارهای شهری ایرانی طی دوره 91-1367 با استفاده از سیستم MAIDADS مورد بررسی قرار گرفت. نتایج حاکی از آن است که خط فقر تغذیهای (ماهانه) طی دوره مذکور روندی افزایشی داشته است بهطوریکه از 74851 ریال در سا...
In this paper we study the welfare effect of a monopoly innovation. Unlike many partial equilibrium models carried out in previous studies, general equilibrium models with non-price-taking behavior are constructed and analyzed in greater detail. We discover that technical innovation carried out by a monopolist could significantly increase the social welfare. We conclude that, in general, the cr...
In this paper we present a model of implementation based on the idea that agents renegotiate unfeasible allocations. We characterize the maximal set of Social Choice Correspondences that can be implemented in Nash Equilibrium with a class of renegotiation functions that do not reward agents for unfeasibilities. This result is used to study the possibility of implementing the Walrasian Correspon...
At arbitrary prices of commodities and assets, fix-price equilibria exist under weak assumptions: endowments need not satisfy an interiority condition, utility functions need only satisfy a very weak monotonicity requirement, and the asset return matrix allows for redundant assets. Prices of assets may permit arbitrage. At equilibrium, though restricted through endogenously determined trading c...
The paper studies the dynamic macroeconomic and welfare effects of tax policy in the context of an overlapping-generations model of the Yaari-Blanchard type for a closed economy. The model is extended to allow for endogenous labor supply and three tax instruments—namely, a capital tax, labor income tax, and consumption tax. It is shown that labor taxes increase welfare of old generations wherea...
A–1 Without loss of generality, assume d1 ≤ d2 ≤ ·· · ≤ d12. If d2 i+2 < d 2 i + d 2 i+1 for some i ≤ 10, then di,di+1,di+2 are the side lengths of an acute triangle, since in this case d2 i < d 2 i+1+d 2 i+2 and d 2 i+1 < d 2 i +d 2 i+2 as well. Thus we may assume d2 i+2 ≥ d2 i + d2 i+1 for all i. But then by induction, d2 i ≥ Fid 1 for all i, where Fi is the i-th Fibonacci number (with F1 = F...
