Abstract
This study aims to determine the effect of the demonstration method on students' reasoning abilities in the topic of lines and angles. This research employs a quasi-experimental design with a nonequivalent control group. Class VII A (37 students) and VII B (37 students) in one of the middle schools in Central Lombok were selected as the sample using purposive sampling. Research data was collected using an essay test instrument. Students' reasoning abilities data were statistically analyzed using the Z-test. Based on the final test results, the average reasoning ability score of the experimental group was 76.95, while that of the control group was 60.56. The Z-test results for students' reasoning abilities yielded a calculated Z value of 0.579, which is greater than the critical Z value of 1.96. As a result, the null hypothesis (Ho) is rejected, leading to the conclusion that there is an influence of the demonstration method on the reasoning abilities of secondary school students.

Background: Pseudomonas aeruginosa is one of the most common Gram negative pathogens associated with nosocomial infections. Carbapenems, specially imipenem and meropenem have the widest activity ranges of any β-lactam antibiotics and are often the most appropriate agents for use in the treatment of infections caused by multi-drug resistant P. aeruginosa. Resistance to carbapenems is emerging, and it is a great problem to therapeutic the serious infections caused by this bacteria.

Authors: Hawraa Ali Atwan  , Hassan Thamir Abdulsahib  
Published: August 2023

In the current study, waste polyvinyl chloride pipes were used as a primary material in the reactions, which are widely used for water supply and drainage systems where the waste pipes were prepared by cleaning them from suspended materials and grinding them into small particles, then reacting natural polymers from a plant; Alginic acid. We have obtained modified polymer (PVC/Alginate) or AL-PVC which have been grinded to obtain a powder. Four methods were used to characterize the properties of natural and prepared polymers: Fourier infrared spectroscopy (FTIR), scanning electron microscopy (SEM) X-ray diffraction (XRD), and thermogravimetry (TGA-TG). The effectiveness of AL-PVC polymer as a coagulant flocculant in the treatment of surface water has been studied. Tests were carried out in the laboratory on two kinds of water (50 NTU and 100 NTU). The first one is the synthesis of water mixed with high and low concentrations of bentonite, simulating thus turbid water. The second one is raw water from the treatment station of the Shatt Al-Arab River. The performance of the coagulation-flocculation process has been assessed by measuring the supernatant turbidity for different pH, doses, and flocculation times of the AL-PVC polymer. The obtained results show that AL-PVC polymer effectiveness was strongly dependent on pH and the doses of AL-PVC polymer, the initial turbidity, and the water quality. The physical and chemical methods used in the present study of water treatments are mainly due to their simplicity, ease of use, low cost as well as excellent removal efficiency.

In this research, we discuss the removal of malachite green dye by strontium hydroxyapatite supported BiOCl. A modified hydrolysis model, one can synthesise BiOCl/SrHA. BiOCl/SrHA was characterized using Fourier transform-infrared spectroscopy (FTIR), UV-visible (UV-vis) analysis, X-ray diffraction (XRD), energy diffraction X-ray (EDX), and scanning electron microscopy (SEM). SEM outcome confirmed the dispersion of BiOCl onto strontium hydroxyapatite. The shape of the BiOCl catalytic samples overlapped with each other to form 3D hierarchical flower-like structures. The UV-visible was used as a radiation source during photocatalysis. BiOCl/SrHA had an effect on malachite green dye degradation. The oxidative removal occurred through hydroxyl radical formation. UV-visible (UV-vis) /BiOCl/SrHA showed perfect photocatalytic property for the decay of malachite green (MG) from an aqueous solution. According to kinetics analysis, the dye degradation rates could be in a pseudo-first-order model.
