The Inclined bed therapy is an ideal natural remedy for several health problems without introducing harmful chemicals or other substances into the patients’ body.The mathematical model of the effect of inclination angle position on the airflow in human trachea under resting and normal breathing condition is presented. The governɨng equatɨons in 2D cylindrical coordinate system of motɨon ϲonsɨstɨng of unsteady, nonlɨnear, non-homogenous, Navɨer-Stokes equatɨons wɨth ɨnɨtɨal and boundary ϲondɨtɨons are analytɨϲally solved usɨng the Adomɨan Deϲomposɨtɨon method. The maɨn advantage of thɨs method ɨs that ɨt ϲan be applɨed dɨreϲtly to all types of dɨfferentɨal equatɨons lɨnear or non-lɨnear, homogeneous or ɨnhomogeneous, wɨth ϲonstant or varɨable ϲoeffɨϲɨents. Another ɨmportant advantage ɨs that, the method ɨs ϲapable of greatly reduϲɨng the sɨze of ϲomputatɨonal work. Results obtaɨned are valɨdated by ϲomparɨson wɨth theoretɨϲal and experɨmental results for the axɨal veloϲɨty. Furthermore, the result is increase of volumetric flow rate leads is found to reduce the resistance to the flow. Consequently, the resistance to airflow is reduced with the increase of inclination angle position, Reynold’s numbers and increase of gravitation (lower Froude number) respectively.Thus, it was justified that sleeping in horizontal position may cause a negative effect on the patient, whereas the inclined position is better and depending on the slope angle, and improved breathing.

The current study included knowledge of the level of anti-tissue transglotaminasTtg (Ab) of both types (IgA-IgG) for males and females celiac patients. The study was conducted in the Public Health Laboratory in Wasit province, where they were diagnosed with celiac disease using measuring the level of Ttg antibodies with both types ( IgA), (IgG) by the ELIZA method. Then, the patients were divided into two groups. The first group included 35 male patients compared with another group that included 40 female patients, whose ages ranged from one year to more than 40 years for both genders.

Pub Date : 2022-07-01 DOI: 10.31185/wjps.10
Shatha Talib Rashid, Noora Saleem Jumaah, Rana Talib
Face recognition is regarded a critical component in the goal of monitoring and securing, particularly for wanted individuals, using a real time recognition algorithm. A Raspberry Pi facial identification will be supplied, with conventional face detection and recognition approaches, to demonstrate how image-based biometrics can be used with a Raspberry Pi. Agencies of law enforcement, like the police, could be outfitted by a covert and safe facial recognition system thanks to the availability of the nano-devices like the Raspberry Pi. The result of the provided suggestion might be a working system that uses Raspberry Pi, OpenCV. The document builds a foundation using such three aspects on systems that may be used in a variety of further scenarios, such as face recognition in combination with low-cost machinery, and cost-effective system for improving law-enforcement services in smart cities.
人脸识别被认为是监控和安全目标的关键组成部分,特别是对于被通缉的个人,使用实时识别算法。将提供树莓派面部识别,与传统的面部检测和识别方法,以演示如何基于图像的生物识别技术可以与树莓派一起使用。由于树莓派等纳米设备的可用性,像警察这样的执法机构可以配备隐蔽而安全的面部识别系统。提供的建议的结果可能是一个使用Raspberry Pi, OpenCV的工作系统。该文件利用这三个方面为系统奠定了基础,这些系统可以在各种进一步的场景中使用,例如与低成本机器相结合的人脸识别,以及改善智能城市执法服务的成本效益系统。

Effect of Titanium Dioxide Nanoparticles (TiO2NPs) on Leishmania parasite in vitro 二氧化钛纳米颗粒(TiO2NPs)对体外利什曼原虫的影响
Pub Date : 2022-07-01 DOI: 10.31185/wjps.21
Raad A. Abd-Algany
The study included detecting the effect of nanoparticles of titanium dioxide nanoparticles (TiO2NPs) with different concentrations (0.5, 1, 5, 10) mg/ml and for two sizes (100, 10) nm on parasites of Leishmania tropica in vitro. The results showed that titanium dioxide nanoparticles (TiO2NPs) have an effect on the parasite with an inverse relationship between growth rate, concentrations of nanoparticles and the exposure period as well as the size of the nanoparticles. The sizes used of titanium dioxide nanoparticles (TiO2NPs) with all their concentrations had a toxic effect on Leishmania promastigote developing in culture media at 48 and 72 hours compared to the control group and that the concentrations of size 10 nm were more effective than concentrations of size of 100 nm on the growth of the parasite during the same time peroids used, and this gives an indication of the importance of using small sizes of titanium dioxide nanoparticles (TiO2NPs) as an anti-growth of Leishmania parasites.
本研究检测了不同浓度(0.5、1、5、10)mg/ml和两种粒径(100、10)nm的二氧化钛纳米颗粒(TiO2NPs)对热带利什曼原虫(Leishmania tropical)寄生虫的体外作用。结果表明,二氧化钛纳米颗粒(TiO2NPs)对寄生虫具有抑制作用,其生长速率、浓度与暴露时间及粒径呈反比关系。与对照组相比,所使用的二氧化钛纳米颗粒(TiO2NPs)的大小及其浓度对培养基中48和72小时发育的promastigote利什曼原虫具有毒性作用,并且在使用的相同时间段内,10 nm的浓度比100 nm的浓度对寄生虫的生长更有效。这表明了使用小尺寸的二氧化钛纳米颗粒(TiO2NPs)作为抗利什曼原虫寄生虫生长的重要性。
