all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
A medium-carbon Cr-Mo-V martensitic steel was thermally processed by quenching (Q) at 890 °C and tempering (T) at increasing temperatures from 650 °C to 720 °C and the effect of tempering temperature, Tt, on sulfide stress cracking (SSC) behaviors was estimated mainly via double cantilever beam (DCB) and electrochemical hydrogen permeation (EHP) tests and microstructure characterization. The re...
OBJECTIVES Once weekly dosing of alendronate has been shown to provide equivalent efficacy to once daily dosing for treatment of osteoporosis in postmenopausal women. Whether patients will prefer weekly dosing to daily dosing for a chronic condition such as osteoporosis has not been studied. The aim of this international study was to assess preference for the weekly or daily dosing regimen of a...
Modules and aspects are different approaches to a common goal of constructing large, complex software quickly. Unfortunately, neither is solely sufficient. We demonstrate that the differences between modules and aspects are not irreconcilable, and that a carefully crafted module system can cater to aspect-oriented features. We show that it is possible to combine the software-engineering feature...
Background: Cystinosis is an inherited metabolic disease in which transfer of cystine out of lysosome is impaired. This phenomenon leads to accumulation of cystine in different organs and causes organ dysfunction. Growth retardation is seen in these patients and later they go on to develop renal failure needing dialysis or renal transplantation. The aim of this study was to evaluate the outco...
statement of the problem: some children do not show an appropriate cooperation with their dentist. a number of them cannot be managed by local anesthesia and the usual techniques used to control behaviors, so further steps are required to control their pain and anxiety. pharmaceutical control is recommended through sedation or general anesthesia. purpose: this study was aimed to evaluate two gr...
