The managers need to have a reasonable guide on the operation and management in district heating system (DHS), so it’s very necessary to predicting the heat load for DHS. In this paper, the relationships between the heat load and weather conditions have been researched in order to determine the inputs variables and output variable of the future heat load prediction model. Using the given data f...

The introduction of highly active antiretroviral therapy (HAART) has significantly decreased morbidity and mortality among patients infected with HIV-1. However, HIV-1 can acquire resistance against all currently available antiretroviral drugs targeting viral reverse transcriptase, protease, and gp41. Moreover, in a growing number of patients, the development of multidrug-resistant viruses comp...

BACKGROUND Many occupational diving groups have substantially different diving patterns to those for which decompression schedules are validated. AIMS To evaluate tuna farm occupational diving practice against existing decompression models and describe a method for collecting and modelling self reported field decompression data. METHODS Machine readable objective depth/time profiles were ob...

The aim of this study is to compare the effects of proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) in the treatment of intertrochanteric fractures in order to investigate the significance of internal fixation in the treatment of intertrochanteric fractures in the elderly. One hundred and eight patients admitted with intertrochanteric fractures and treated with PFNA and DHS...

The subtrochanteric region has certain anatomical and biomechanical features that can make fractures in this region difficult for the treating surgeon. The preferred type of device is a matter of debate. Increased understanding of mechanical characteristics of the dynamic hip screw (DHS) has reduced the incidence of complications. Our hypothesis is based on the technical optimization of the DHS...

The problem of reliability of new object of distributed hardware software (DHS) multi-agent system (MAS) is considered. DHS MAS is determined as a system that is based on agent technologies and consists of both agents and hardware components required for execution of agents and for interaction of agents with an environment. Reliability improvement, fault-recovery and several reliability assessm...

the effect of salinity on organic removal and ammonium oxidation in a down-flow hanging sponge reactor was investigated by conducting a long-term continuous experiment over a period of 800 days. the dhs reactor, constructed by connecting three identical units, was fed with artificial wastewater containing 500 mg-n/l of ammonium nitrogen and 1400 mg- cod/l of phenol. salinity of the influent wa...

OBJECTIVE The goal of this study was to measure the impact of the new 2011 Accreditation Council for Graduate Medical Education duty hour standards (DHS) on education, patient care, and overall satisfaction as perceived by pediatric hospitalist faculty. METHODS We undertook a nonrandomized but controlled study of 23 pediatric hospitalist faculty members during a trial of the new DHS in 2011. ...

A water-soluble selenoxide (DHS(ox)) having a five-membered ring structure enables rapid and selective conversion of cysteinyl SH groups in a polypeptide chain into SS bonds in a wide pH and temperature range. It was previously demonstrated that the second-order rate constants for the SS formation with DHS(ox) would be proportional to the number of the free SH groups present in the substrate if...

In this paper we will apply the tensor and its traces to investigate spectral characterization of unicyclic graphs. Let $G$ be a graph $G^m$ $m$-th power (hypergraph) $G$. The spectrum is referring adjacency matrix, tensor. called determined by high-ordered spectra (DHS for short) if, whenever $H$ such that $H^m$ cospectral with all $m$, then isomorphic first give formulas graphs, provide some ...
