A multi-period location-allocation model for nursing home network planning under uncertainty

This paper proposes a multi-period location- allocation problem arising in nursing home network planning. We present a strategic model in which the improvement of service accessibility through the planning horizon is appropriately addressed. Unlike previous research, the proposed model modifies the allocation pattern to prevent unacceptable deterioration of the accessibility criterion. In addition, the problem is formulated as a covering model in which the capacity of facilities as well as the demand elasticity are considered. The uncertainty in demands within each time period is captured by adopting a distributionally robust approach. The model is then applied to a real case study for nursing home planning network in Shiraz city, Iran

Effect of spark plasma sintering and high-pressure torsion on the microstructural and mechanical properties of a Cu–SiC composite

This investigation examines the problem of homogenization in metal matrix composites (MMCs) and the methods of increasing their strength using severe plastic deformation (SPD). In this research MMCs of pure copper and silicon carbide were synthesized by spark plasma sintering (SPS) and then further processed via highpressure torsion (HPT). The microstructures in the sintered and in the deformed materials were investigated using Scanning Electron Microscopy (SEM) and Scanning Transmission Electron Microscopy (STEM). The mechanical properties were evaluated in microhardness tests and in tensile testing. The thermal conductivity of the composites was measured with the use of a laser pulse technique. Microstructural analysis revealed that HPT processing leads to an improved densification of the SPS-produced composites with significant grain refinement in the copper matrix and with fragmentation of the SiC particles and their homogeneous distribution in the copper matrix. The HPT processing of Cu and the Cu-SiC samples enhanced their mechanical properties at the expense of limiting their plasticity. Processing by HPT also had a major influence on the thermal conductivity of materials. It is demonstrated that the deformed samples exhibit higher thermal conductivity than the initial coarse-grained samples

Determination of energy gain time dependent in D+T mixture with calculating total energy deposited of deuteron beam in hot spot

The fast ignition (FI) mechanism, in which a pellet containing the thermonuclear fuel is first compressed by a nanosecond laser pulse, and then  irradiated by an intense "ignition" beam, initiated by a  high power picosecond laser pulse,  is one of the promising approaches to the realization of the inertial confinement fusion (ICF). If the ignition beam is composed of deuterons, an additional energy is delivered to the target, coming from fusion reactions of the beam-target type, directly initiated by particles from the ignition  beam .In this work, we choose the D+T fuel and  at first step we compute the average reactivity in terms of temperature for first time at second step we use the obtained results of step one and calculate the total deposited energy of deuteron beam inside the target fuel at available physical condition then in  third step we introduced the dynamical balance equation of D+T mixture and solve these nonlinear  differential coupled  equations versus time .In forth step we compute the power density and energy gain under physical optimum conditions and at final step we concluded that  maximum  energy deposited  in the target from D+T and D+D reaction are equal to  to19269.39061 keV and 39198.58043 keV respectively. &nbsp

Data for: The effect of cognitive load on economic decision making: A survey and new experiments

Abstract of associated article: Psychologists and economists have examined the effect of cognitive load in a variety of situations from risk taking to snack choice. We review previous experiments that have directly manipulated cognitive load and summarize their findings. We report the results of two new experiments where participants engage in a digit-memorization task while simultaneously performing a variety of economic tasks including: (1) choices involving risk, (2) choices involving intertemporal substitution, (3) choices with anchoring effects, (4) choices over healthy and unhealthy snacks, and (5) math problems. We find that higher cognitive load reduces numeracy as measured by performance in math problems. Moreover, within-subject analysis indicates that cognitive load leads to more risk-averse behavior, more impatience over money, and (nominally) more likelihood to anchor. We do not find any evidence that cognitive load increases impatience over consumption goods or unhealthy snack choices. Exploiting the panel nature of our data set, we find that those individuals who are most sensitive to cognitive load, as measured by a large drop in their own math performance across 1- and 8-digit memorization treatments, are driving much of the effect

On g−g-Fusion Frames Representations via Linear Operators

Let $\{\frak{M} _k \} _{ k \in \mathbb{Z}}$ be a sequence of closed subspaces of Hilbert space $H$, and let $\{\Theta_k\}_{k \in \mathbb{Z}}$ be a sequence of linear operators from $H$ into $\frak{M}_k$, $k \in \mathbb{Z}$. In the definition of fusion frames, we replace the orthogonal projections on $\frak{M} _k$ by $\Theta_k$ and find a slight generalization of fusion frames. In the case where, $\Theta_k$ is self-adjoint and $\Theta_k(\frak{M} _k)= \frak{M} _k$ for all $k \in \mathbb{Z}$, we show that if a $g-$fusion frame $\{(\frak{M} _k, \Theta_k)\}_{k \in \mathbb{Z}}$ is represented via a linear operator $T$ on $\hbox{span} \{\frak{M} _k\}_{ k \in \mathbb{Z}}$, then $T$ is bounded; moreover, if $\{(\frak{M} _k, \Theta_k)\}_{k \in \mathbb{Z}}$ is a tight $g-$fusion frame, then $T$ is not invertible. We also study the perturbation and the stability of these fusion frames. Finally, we give some examples to show the validity of the results

A Study on Antimicrobial Effects of Plantago Psyllium

Introduction & Objective: Due to emergence of resistance of antibiotics to microorganisms, investigations for novel antimicrobial agents have always been one of the major preoccupations of the medical societies. The present investigation aimed to study the antimicrobial properties of Plantago psyllium on some of pathogen microorganisms. Materials & Methods: This experimental study was carried out at Yasouj University of Medical Sciences in 2010. After collection and preparation of hydroalcoholic extract of Plantago psyllium, its effects against human pathogen microorganism (overall 10 microorganisms) were evaluated. Minimal Inhibitory Concentration (MIC) and minimum lethal concentration were determined for this extract. The antimicrobial effect of Plantago psyllium extract with commercial antimicrobial agents were compared. Collected data were analyzed by SPSS software using one-way ANOVA and chi-square test. Results: Findings of the present study revealed that in l0 mg/ml and 20 mg/ml concentrations of the extract, all bacteria were resistant to Plantago psyllium. In 40 mg/ml concentration, only Staphylococcus areus and staphylococcus epidemidis showed zone of inhibition (ZOI) of 10 mm and 13 mm respectively while in 80 mg/ml concentration, the maximum ZOI was 20 mm in Staphylococcus areus and 18 mm in staphylococcus epidemidis. The acceptable MIC and MLC were 40 mg/ml and 80 mg/ml in Staphylococcus areus and staphylococcus epidemidis respectively. Conclusion: Our data clearly indicated that the extract displayed equivalent compatibility with standard antibiotics on Staphylococcus areus and staphylococcus epidemidis bacteria
