Numerous physiological and biochemical changes are linked to menopause. The current study was intended to examine the transforms linked to anthropometric measurements and bone-related factors. In this study of 80 women which included; they comprised 40 premenopausal women and 40 postmenopausal women. waist circumference (WC), body mass index (BMI), hip circumference (HC), moreover waist to hip ratio are among the anthropometric measurements (W-HR) recorded by standard procedures. The plasma samples were tested for the following biochemical parameters: bone-related parameters [calcium (Ca), phosphorus (P), uric acid (UA), alkaline phosphatase (ALP), and erythrocyte sedimentation rate (ESR)] and serological agglutination tests [rheumatoid factor (RF) and C-reactive protein (CRP)]. The mean of BMI, WC, and W-HR was significant (p<0.05) and much higher in postmenopausal women than their values in perimenopause women, while a non-significant (p>0.05) difference was found in the mean of HC between the two groups. The findings revealed that postmenopausal women's levels of Ca were substantially (p0.05) lower than premenopausal women's levels, while postmenopausal women's levels of P were significantly (p0.05) greater than premenopausal women's levels. In comparison to premenopausal women, post-menopause women had significantly higher levels of UA, ALP, and ESR (p<0.05). The results revealed that the number and percentage of CRP positive women out of the premenopausal women are only 8 (20 %), while the number and percentage of CRP-positive women out of the postmenopausal women are only 18 (45%); the differences are significant (p<0.05). Also, the results revealed that the number and percentage of RF positive women out of the premenopausal women are only 5 (12.5 %), while the number and percentage of RF-positive women out of the postmenopausal women are only 15 (37.5%). The differences are significant (p<0.05). According to the results, postmenopausal women had significant (P<0.05) higher rates of all chronic illnesses than premenopausal women. On the other hand, the prevalence of bone-related disease was substantially (P<0.05) greater in the premenopausal women (30%) and postmenopausal women (45%) research groups as well as the overall study population of women (37.5%). In conclusion, changes related to age in the anthropometric measurements and in the bone-related parameters, accompanied by reduced physical activity may all lead to the installation of several chronic diseases among postmenopausal women.
This paper attempted to study the effect of cutting parameters (spindle speed and feed rate) on delamination phenomena during the drilling glass-polyester composites. Drilling process was done by CNC machine with 10 mm diameter of high-speed steel (HSS) drill bit. Taguchi technique with L16 orthogonal layout was used to analyze the effective parameters on delamination factor. The optimal experiment was no. 13 with spindle speed 1273 rpm and feed 0.05 mm/rev with minimum delamination factor 1.28. &

Four epoxy samples of (E/clay/B4C) S1, (E/Mag/B4C) S2, (EPIL) S3 and (Ep) S4 were used in a comparative study of gamma radiation attenuation properties of these shields that calculating using Mont Carlo code (MCNP-5). Adopting Win X-com software and Artificial Neural Network (ANN), µ/ρ revealed great compliance with MCNP-5. By applying (µ/ρ) output for gamma at different energies, HVL, TVL and MFP have been also estimated. ANN technique was simulated to estimate (µ/ρ) and dose rates. According to the results, µ/ρ of all epoxy samples scored higher than standard concrete. Both S2 and S3 samples having h

Show MoreThe Indian costus plasma properties are investigated including electron temperature (Te), "electron density (ne)", "plasma frequency (fp)", " Debye sphere length", and amount of Debye(Nd), using the spectrum of optical emission technique. There are several energies used, with ranging from 300 to 600 mJ. The Boltzmann Plot is used to calculate the temperature; where as Stark's Line Broadening is used to calculate the electron density. The Indian costus was spectroscopically examined in the air with the laser at 10 cm away from the target and the optical fiber at 0.5 cm away. The results were obtained for an electron temperature range of (1.8-2.2) electron volts (ev) and a wavelength range of (300-600) nm. The XRF analysis reveals th

Materials and methods: A standard model from ivoclar company was used as a pattern to simulate three-units bridge (upper first molar and upper first premolar) as abutments used to fabricate stone models, eight single crowns for premolar and eight of three units bridges. Crowns and bridges fabricated by CAD-CAM system were cemented on their respective stone models then sectioned at the mid-point buccolingaully and misiodistaly and examined under stereomicroscope.
