... Show MoreThe shift in the critical perspective splits an episteme in two. A line of demarcation identical to the paradigm shift separates the new epistemes in a way that the critical insight should differ drastically on both sides of the line. Michel Foucault sorts these historical epistemes as Renaissance and Classical epistemes, then he included the Modern episteme as a latter historical era, and the line of distinction between one episteme and another is the critical insight that the involved mentality adopts. When it comes to the source of the influence of human behavior, the change in perspective in the consideration of the source of the influence is clarified in the compariso

The endimicity of the disease among Iraqi elementary schoolchildren was investigated during the period from January to May 2009 in the city of Baghdad. From eight elementary schools, 540 boys and girls were included in the study. The total rate of infestation was 13.5%, however this rate was significantly higher among girls (17.33%) comparing to boys (8.75%). The prevalence rate was found to be highly influenced by certain factors. These were including the age (the rate was significantly higher (18.7%) among the age group of >8-10 years compared to other age groups), the hair characters (the rate was significantly high
... Show MoreMany neuroscience applications, including understanding the evolution of the brain, rely on neural cell instance segmentation, which seeks to integrate the identification and segmentation of neuronal cells in microscopic imagery. However, the task is complicated by cell adhesion, deformation, vague cell outlines, low-contrast cell protrusion structures, and background imperfections. On the other hand, existing segmentation approaches frequently produce inaccurate findings. As a result, an effective strategy for using the residual network with attention to segment cells is suggested in this paper. The segmentation mask of neural cells may be accurately predicted. This method is built on U-net, with EfficientNet serving as the e

Since the end of 2019, humans have been under threat due to a disease called (COVID-19), which was first reported in China. Many methodical approaches have been reported to quantify chloroquine and hydroxychloroquine in blood, urine, plasma, serum, and pharmaceutical dosage form. Some of these techniques are spectrophotometry, liquid chromatography with a mass detector, gas chromatography, and ultra-performance, high-performance liquid chromatography (HPLC), in addition to electrochemical methods. This literature review discusses various analytical methods for the determining hydroxychloroquine and chloroquine.
Model birefringence was measured for elliptical-core fibers with low ellipticities, note the birefringence depends strongly on the frequency, especially when fiber is being operated near the higher mode cutoff where ν for circular fiber of the single-mode type that correspond to the birefringence maximum. When ν this also correspond to the birefringence maximum that can be introduced in an elliptical core fiber while still operating in the single-mode regime near the higher mode cutoff. Also the birefringence is proportional to the fiber core ellipticity when core ellipticity is much less than unity, but this birefringence deviates from the linear for the large core ellipticities.
A hyperboloid solar concentrator (HSC) was designed with a truncation angle side to the entrance aperture by simulation in the Zemax Optical Design software. The (HSC) has a wide exposure range to solar radiation due to the relatively large entrance aperture. The design consists of an entrance aperture facing the sun to obtain the largest possible amount of solar radiation, and a small exit aperture compared to the entrance aperture whose mission is to receive solar radiation after it enters the entrance aperture and reflects it from the inner reflective walls of the (HSC). In the exit aperture, there is a detector to measure the number of rays incident on it, which is a measure of the optical efficiency of the s
