Abstract

Aluminum metal matrix composites find applications in several industries, such as aerospace, military, cars, sports equipment, and electronics. The primary objective of this experimental study is to obtain insights into the microstructural properties of an Al-Zn alloy that has been strengthened with copper. This investigation involved the preparation of an alloy including aluminum and zinc, which was afterward reinforced with varying quantities (0%, 0.4%, 1.2%, and 2%) of copper. In addition to conducting XRD tests to investigate the crystallite structure, particle size, and microscopic strain of the samples using the Scherrer and Williamson-Hall models, structural examinations were carried out using the EDS test to ascertain the elemental composition proportions. It was observed that the alloy (A-Zn-0.4%Cu) has smaller particle sizes than the other alloys under consideration. [ABSTRACT FROM AUTHOR]

Abstract

The attenuation coefficients and building up factor (BF) of two different specimens of organic compound (paraffin wax) and sodium chloride structures were measured using gamma rays from radioactive sources (124Am, 137Cs, 226Ra) with energies (60, 662, 186, 242, 295, 352, 609, 1120, 1765) keV respectively. These two samples were measured with a gamma ray integrated computer spectrometer (ICS). This system is controlled by a computer using a custom-written programme and is linked to a sodium iodide activated thallium detector that measures just 1.5 inches by 1.5 inches. The radioactive source and detector were placed in the same room as the specimen. There was a 900-second accumulation time. With the (USX PCI) software, we were able to calculate the photopeak, net area, and FWHM of photopeak. Measured data was compared to the ICRU Report 44 value. When an organic compound and sodium chloride are combined, the attenuation coefficients are less than 7% different from what would be expected in human tissue. Results from this study suggest that the materials used for dosimetry could also be used to create tissue phantoms that accurately represent the biological tissues under investigation.

Abstract

BACKGROUND: Tamoxifen has an estrogenic effect on the liver, lead to increase the danger of gallstone development. AIM: This study aimed to determine the prevalence of gall bladder stones formation during tamoxifen therapy. METHODS: A prospective casecontrol study enrolled 14 premenopausal and 36 postmenopausal females. The gall bladder condition was assessed by abdominal ultrasound using “Alpinion Portable Color Doppler E-CUBE,” in addition, clinical parameters collected as age and weight of patients. RESULTS: Approximately, 14 (28%) of women were premenopausal their age ranged from (25 to 44) years, and 36 (72%) postmenopausal females their age was between (45 and 78) years. The duration of tamoxifen therapy was (range >–72) months, with 33 control cases. All cases examined by pelvic ultrasound, only 11 (22%) showed gall bladder stones. The gall bladder stones were diagnosed, in 4 of premenopausal, whereas seven patients were postmenopausal. There is a significant relation with gall bladder stones with increase body weight during therapy. CONCLUSION: There is a significant correlation between gall bladder stones formation and tamoxifen therapy. Postmenopausal women have a higher risk of developing gall bladder stones formation.
