An anomalous dependence of the lattice parameter on the crystallite size of nanocrystalline ball-milled powders of metals was observed: lattice contraction followed by lattice expansion with decreasing crystallite size. These data were determined by application of detailed Xray diffraction measurements. To this end, the lattice parameters of all the metals were accurately determined by correcti...

This paper argues that more rigorous evaluations of local economic development policies are feasible. Programs that aid selected small firms can be rigorously evaluated using an experimental approach, without excluding firms from assistance, by randomly assigning some firms to receive more intense marketing efforts by the program. Programs that aid distressed local areas can be rigorously evalu...

The double travelling salesman problem with multiple stacks (DTSPMS) is a pickup and delivery problem in which all pickups must be completed before any deliveries can be made. The problem originates from a real-life application where a 40 foot container (configured as 3 columns of 11 rows) is used to transport up to 33 pallets from a set of pickup customers to a set of delivery customers. The p...

This article agrees with recent arguments suggesting that normative and epistemic power is rife within global health policy and provides further examples of such. However, in doing so, it is argued that it is equally important to recognize that global health is, and always will be, deeply political and that some form of power is not only necessary for the system to advance, but also to try and ...

I WANT TO FOCUS ON A SINGLE WORK OF LITERATURE. It is not directly concerned with war among states, though its author, Choderlos de Laclos, was in fact a soldier, an artillery officer, and an expert in fortifications. It deals with other kinds of war. My goal today is to consider the place of reason—of rational choice in the commonsense version of this term—and, specifically, of rational choice...

In our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. The objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). The urban form design will bediscussed through the simulation of airflow by using Computation...

in this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed form relations a...

Acutepancreatitis can infrequently be a life-threatening complication of hypertriglyceridemia. Rarely, hypertriglyceridemia can originate from an inborn genetic error in lipoproteins metabolism. This condition can be manifested by very high serum triglyceride levels (>1000 mg/dl) and a more severe and lethal form of pancreatitis. Here, we present a case of acute pancreatic which was found out t...

in this paper, we propose a new approach for ranking all fuzzynumbers based on revising the ranking method proposed by ezzati et al. cite{ezzati}.to this end, we present and investigate some properties of the proposed approach indetails. finally, to illustrate the advantage of the proposed method, it is applied to several groups of fuzzy numbers and the results are compared with other related a...
