background: every year millions of dollars are expended to equip and maintain the hospital sterilization centers, and our country is not an exception of this matter. according to this, it is important to use more effective technologies and methods in health system in order to reach more effectiveness and saving in costs. this study was conducted with the aim of evaluating the technology of regi...

In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...

This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...

Incorporating spatial econometric tools in Hedonic Pricing (HP) models for environmental valuation has become the standard approach in the literature. The effect of house prices on other house prices is taken into account and usually measured by distance or contiguity in spatial weight matrices. Disaggregate house sale datasets are composed from observations each at a specific location and time...

The study was conducted to determine the prevalence of goiter and hypothyroidism in two groups of the population at various stages of social development and to determine its association with malnutrition and dietary intake. Aboriginal inhabitants (Orang Asli), a resettlement rural village (Betau Post), a traditional village in the jungle (Lanai Post) and a modern village settlement near Kua...

In this paper, we provide an asymptotic for the number of row-Fishburn matrices of size n which settles a conjecture by Vit Jeĺınek. Additionally, using q-series constructions we provide new identities for the generating functions for the number of such matrices, one of which was conjectured by Peter Bala.
