A new method for analysis of trace amount of Rh(III) ions by magnetic activated carbon modified with 2,3,5,6-tetra(2-pyridyl)pyrazine (MAC/TPPZ) as the magnetic sorbent has been proposed. The proposed adsorbent was found to be advantageous over conventional solid phase extraction (SPE) in terms of operational simplicity and low time-consuming. The experimental parameters affecting the extractio...

Microalgae produce a wide range of lipid compounds of potential commercial interest. Total lipid extraction performed by conventional extraction methods, relying on the chloroform-methanol solvent system are too laborious and time consuming for screening large numbers of samples. In this study, three previous extraction methods devised by Folch et al. (1957), Bligh and Dyer (1959) and Selstam a...

introduction: erythrocyte sedimentation rate (esr) remains as one of the most reliable tests in clinical practices. yet its use is time consuming and requires a large blood sample. the aim of this study was assessing a faster and reliable method of esr estimation. methods: an esr estimation method was described and performed on 108 patients using capillary tube (micro esr) and capillary periphe...

The prediction of aerodynamic characteristics and smart flap of airfoil under the ground effect are carried out by the integration of computational fluid dynamics. Considering different types of beams, a parametric bending profile of a smart flap is designed. Cantilever beam with uniformly varying load with roller support at the free end is considered in here. A pressure-based implicit procedur...

A two-step coating/precipitation synthetic procedure has been developed for the preparation of cellulose tris(3,5-dimethylphenylcarbamate) chiral stationary phase (CSP) having a small-pore silica support. With this synthetic strategy, monodisperse, spherical CSP particles can be produced without the need for a wasteful and time-consuming sieving process. The performance of the synthesized CSP t...

The most widely used method for routine antibiotic susceptibility testing of clinical isolates of bacteria is the paper-disc method. This has the advantage of simplicity, but to obtain reliable results considerable care is required both in the standardization of the procedure and in the interpretation of the zones of inhibition. A new susceptibility test method is described in this report which...

The purpose of this in vitro study was to compare the time efficiency digital chairside and labside workflows with a conventional workflow for single-unit restorations. specific sense defined as time, which has be spent dental office by professional performing relevant steps. A model interchangeable teeth on position 36 created. These were differently prepared, responding several clinical situa...
