Hematological and chemical tests have been used as tools to report some blood indexes means and confidence intervals (95%) of the adult "Moorish" or "Greek" male and female tortoises, Testudo graeca Linnaeus, 1758. The area of study was limited to Benghazi province, Libya. Cardiocentesis was employed to obtain blood samples from 25 males and 25 females, which apparently looked healthy tortoises. The anticoagulant of choice, when it was needed, was lithium heparin to avoid destructive effects of the potassium ethylenediaminetetraacetate on cellular elements. Means of the erythrocytes counts as well as confidence intervals of both sexes were below the million per cubic millimeter.
Parametric Optimization of Shielded Metal Arc Welding Processes by Using Factorial Design Approach
An auspicious method for the quantitative determination of vitamin A (retinol) was augmented in seven different Jordanian local fresh milk samples using liquid chromatography tandem -mass spectrometry (LC/MS/MS). The compound was separated with C18 Thermo fisher gold (4.50 x100 mm x 5 Å) column through a flow rate of 1 mL/min with isocratic mobile phase. Vitamin A acetate was used as an internal standard .The method was validated using triplicate analyses, relative recovery experiment and statistical analysis. Liquidliquid extraction was employed as a pre-concentration step with n-hexane -dichloromethane mixture (90%:10%) as an extraction solvent. The concentration range of the working standards was 0.0-1000.0 ng/mL. The correlation coefficient was found to be 0.9994. The limit 0f detection and limit of quantification were found to be 0.53 and 1.78 respectively. The 95% confidence interval was calculated to be 49.032 + 0.22.
The Shielded Metal Arc Welding (SMAW) process is an arc welding process which produces coalescence of metal by heating them with an arc between a covered metal electrode and the work. Shielding is obtained from decomposition of the electrode covering. Pressure is not used.
