Metacognitive Skills among Left-Handed Students in Al-Quds university

The aim of this study was to reveal the metacognitive skills among left-handed students at Al-Quds University. The study population consisted of all left-handed students at Al-Quds University. Data obtained from a purposive sample of 47 left-handed male and female students was analyzed using Statistical Package for Social Sciences (SPSS). The findings showed that left-handed students at Al-Quds University had a low degree of metacognitive skills. It was found that there were differences attributable to gender in favor of female students, but no differences attributable to college (Science and Humanities). The findings also revealed differences due to the overall grade point average (GPA) in favor of the students with a GPA of more than 80%. It is recommendedthat students must be taught metacognitive strategies through: helping them to plan and evaluate their learning process, stimulating their thinking processes by giving them assignments that require higher levels of thinking and challenge their mental abilities in order to obtain knowledge during th

A hplc-uv method for deteermination of three pesticides in water

HPLC method is developed and validated for determination of three pesticides (abamectin, imidacloprid, and -cyfluthrin) in water. These pesticides are used widely in agriculture for crops protection, and may be leached to the groundwater. Reversed-phase method with C18 column (5 μm, 250mm × 4.6 mm inner diameter) using a mobile phase consisting of acetonitrile/water (v:v = 4:1) at a flow rate of 1.5 mL/min and UV detection at 220 nm was used. This method is validated according to new methods which include accuracy, precision, linearity and range, limit of detection and limit of quantitation. The current method exhibits good linearity over the range of 1-1000 ppb for abamectin, 0.5-1000 ppb for imidacloprid, and 0.4-1000 ppb for ß-cyfluthrin with r2 greater than 0.990. The percentage recovery of the method at three concentration levels (5, 100, and 1000 ppb) is within 97.6 to 101.5% for the three pesticides. Relative standard deviation of the area of six replicate injections of each pesticide at three concentration levels (5.0, 100.0, and 1000.0 ppb) was found to be less than 1% which reflect the precision of the method. Limit of quantitation of the three pesticides using this method is low (1.0, 0.5, and 0.4 ppb) for abamectin, imidacloprid, and -cyfluthrin, respectively which enables the determination of these three pesticides in water at low concentration levels

Development and Validation of HPLC-UV Method for Determination of Bovine Serum Albumin and Myoglobin Proteins

A simple HPLC with UV detection method is developed and validated for determination of Bovine Serum Albumin and Myoglobin proteins in a standard solution of the two protein as well as in a plasma spiked with theses two proteins. Separation was achieved on a reversed-phase C18, 5.0 μm, 150mm × 4.6 mm inner diameter column using a mobile phase consisting of solution A (900 mL of water, 100 mL Acetonitrile, 10 mL Trifluroacetic acid) and solution B (900 mL of acetonitrile, 100 mL water, 10 mL Trifluroacetic acid) with gradient elution of 5 to 50% of solution B in 15 minutes. This new method is validated in accordance with requirements for new methods, which include accuracy, precision, selectivity, linearity and range, robustness, limit of detection and limit of quantitation. The method demonstrates good linearity over the range of 1-1000 ppm for the two proteins with r2 greater than 0.998. The percentage recovery of the method is within 97.9 to 102.0% for the two proteins. Precision of this method reflected by relative standard deviation of the area of six replicate injections of each protein at five concentration levels (1.0, 100.0, 300.0, 500, and 1000.0 ppm) was found to be less than 2%. Limit of quantitation of the two proteins is low which enables the determination of these proteins at low concentration

Development and Validation of a Simple Reversed‑Phase HPLC‑UV Method for Determination of Malondialdehyde in Olive Oil

A simple, precise, accurate and selective method was developed and validated for determination of malondialdehyde (MDA) in olive oil. Separation was achieved on a reversed-phase C8 column using a mobile phase consisting of methanol/0.8 % phosphoric acid (10:90, v/v), at a flow rate of 1.0 ml/min and UV detection at 220 nm. This method was validated according to the requirements for new methods, which include accuracy, precision, selectivity, robustness, a limit of detection, limit of quantitation (LOQ), linearity and range. The current method demonstrated good linearity over the range of 0.5–1000 ppm of MDA with r2 greater than 0.999. The recovery of MDA in olive oil ranged from 97.1 to 99.1 %. The method was selective where MDA was distinctly separated from other compounds of the oil with good resolution. The method was also precise where the RSD of the peak areas of replicate injections of MDA standard solution were less than 1 %. The degree of reproducibility of the results obtained as a result of small deliberate variations in the method parameters and by changing the analytical operators proved that the method is robust and rugged. The low LOQ of MDA (0.5 ppm) using this method enables quantitation of MDA at low concentration
