background: studies showed that poor quality of sleep is a common problem among the elderly. because of drug complications and side effects such as drug dependency and resistance and decrease of sleep depth in long‑term intake of sleep medication, cognitive‑behavior therapy including sleep restriction therapy which does not cause these problems is more considered. materials and methods: this is...

the effectiveness of any drug supply systems in providing a trustworthy supply of essential drugs is a critical issue. to evaluate this effectiveness, it is necessary to watch over the status of the essential medicines in any country impartially and continuously. some countries and also the world health organization (who) have codified a list of minimum medicines needed for a basic health care ...

The potential health risks associated with the pharmaceuticals released into environment through effluents from sewage treatment plants have become a major cause for concern. Owing to lack of effective indicators, monitoring concentration these pollutants in aquatic is challenging. aim this study was assess toxicity mixture five pharmaceutical drugs (paracetamol, carbamazepine, diclofenac, irbe...

New experimental data on liquid-liquid equilibria (LLE), solubility and critical states in quaternary system propionic acid – 1-propanol n-propyl propionate water at 303.15 K atmospheric pressure are presented. LLE was studied by Gas Chromatography (GC). Solubility (plait) points were investigated “cloud-point technique” method. Binodal curves surfaces presented concentration tetrahedron. The c...

Introduction Pre-Quaternary paleoclimate modeling is the science of simulating climate change over the earliest 99.9% of Earth’s history using numerical models of the climate system. The record of pre-Quaternary climate documents enormous climate swings with global ice-covered and ice-free end members. A number of climate factors shaped Quaternary and pre-Quaternary paleoclimate on timescales r...

Introduction: Although patients do not experience sever pain after laparoscopic surgery, most of them experience acute or chronic pain afterward. While conventional pain killers including NSAID and narcotics in laparoscopic surgery have specific side effects, their application is inevitable. This study compares the efficacy of local anesthetic drugs and conventional pain killers in post-operati...

In this paper, a new construction method of quaternary sequences of even period 2N having the ideal autocorrelation and balance properties is proposed. These quaternary sequences are constructed by applying the inverse Gray mapping to binary sequences of odd period N with the ideal autocorrelation. Autocorrelation distribution of the proposed quaternary sequences is derived. These sequences can...

In this work, a novel quaternary algebra has been proposed that can be used to implement any quaternary logic function. Unlike other variants of quaternary algebra, this algebra is closely related to Boolean algebra and can be used to convert any binary function into quaternary without any significant modification. For this purpose, we have defined a set of quaternary operators and developed tw...

A simple, specific, accurate and precise spectrophotometric method was developed validated for simultaneous estimation of Betamethasone Luliconazole in Synthetic Mixture. The wavelength 243.20 nm 225.00 nm. Beer’s law is obeyed the concentration range 10-50μg/ml 20-100μg/ml correlation coefficient 0.999 respectively. % recovery were found to be 100.49 & - 100.68 Intraday precision 0.10 %– 0...
