Graphene-carbon nitride can be synthesized from thiourea in a single step at a temperature of four hours at a rate of 2.3 ℃/min. Graphene-carbon nitride was characterized by Fourier-transform infrared spectroscopy (FTIR), energy dispersive X-ray analysis (EDX), scanning electron microscopy, and spectrophotometry (UV-VIS). Graphene-carbon nitride was found to consist of triazine and heptazine structures, carbon, and nitrogen. The weight percentage of carbon and the atomic percentage of carbon are 40.08%, and the weight percentage of nitrogen and the atomic percentage of nitrogen are 40.08%. Therefore, the ratio and the dimensions of the graphene-carbon nitride were characterized by scanning electron microscopy, and it was found that the radius was within the range of (2 µm-147.1 nm). In addition, it was found that it absorbed light in the visible field (VIS). The objective of the manufacture and characterization of graphene-carbon nitride for use in the manufacture of a selective electrode for an organic pollutant (currently used in the manufacture of a selective electrode for the analysis of organic dye).
以硫脲为原料,以2.3℃/min的速度在4小时的温度下一步合成了石墨烯-氮化碳。采用傅里叶变换红外光谱(FTIR)、能量色散x射线分析(EDX)、扫描电镜和分光光度法(UV-VIS)对石墨烯-氮化碳进行了表征。石墨烯-氮化碳由三嗪和七嗪结构、碳和氮组成。碳的重量百分比和碳的原子百分比为40.08%,氮的重量百分比和氮的原子百分比为40.08%。因此,通过扫描电镜对石墨烯-氮化碳的比例和尺寸进行了表征,发现其半径在(2µm-147.1 nm)范围内。此外,还发现它在可见光场(VIS)中吸收光。石墨烯-氮化碳的制造和表征的目的是用于制造有机污染物的选择电极(目前用于制造用于分析有机染料的选择电极)。

The study of fixed points on the  maps fulfilling certain contraction requirements has several applications and has been the focus of numerous research endeavors. On the other hand, as an extension of the idea of the best approximation, the best proximity point (ƁƤƤ) emerges. The best approximation theorem ensures the existence of an approximate solution; the best proximity point theorem is considered for addressing the problem in order to arrive at an optimum approximate solution. This paper introduces a new kind of proximal contraction mapping and establishes the best proximity point theorem for such mapping in fuzzy normed space ( space). In the beginning, the concept of the best proximity point was introduced. The concept of proximal contractive mapping in the context of fuzzy normed space is then presented. Following that, the best proximity point theory for this kind of mapping is established. In addition, we provide an example application of the results

The results of the current study showed that the thyroid gland in an adult domestic cat (Felis catus) is located in the neck area on both sides of the trachea at rings 1–5. The gland consists of two lobes (right and left), and it is surrounded by a capsule of connective tissue consisting of two outer and inner layers, and a layer of fatty tissue overlaps with the outer layer of the capsule. In addition, the results of this study found that the histological structure of the thyroid gland is composed of several follicles that appear in different sizes and shapes. The follicles are lined with simple cuboidal epithelial tissue and sometimes appear lined with high and low simple cuboidal epithelial tissue. The gland is histologically composed of two types of cells: epithelial cells and parafollicular cells, or calcitonin cells (C-cells), the latter being few in number compared to the epithelial cells and appearing as single cells or forming clusters in two locations: the first is between the follicular and the second is intrafollicular.
本研究结果表明,成年家猫(Felis catus)的甲状腺位于气管两侧环1-5处的颈部区域。腺体由两个叶(右叶和左叶)组成,它被由两层外层和内层组成的结缔组织包膜包围,一层脂肪组织与包膜的外层重叠。此外,本研究结果发现甲状腺的组织学结构是由几个大小形状各异的卵泡组成的。卵泡内排列有单层立方上皮组织,有时排列有高低单层立方上皮组织。腺体在组织学上由两种类型的细胞组成:上皮细胞和滤泡旁细胞或降钙素细胞(c细胞),后者与上皮细胞相比数量较少,在两个位置表现为单个细胞或形成集群:第一个在滤泡之间,第二个在滤泡内。

A new family of distribution named Double-Exponential-X family is proposed. The proposed family is generated from the double exponential distribution. The forms of the probability densities and hazard functions of two distinct subfamilies of the proposed family are examined and reported. Generalproperties such as moment, survival, order statistics, probability weighted moments and quartile functions of the models are investigated. A sub family of the developed family of double –Exponential-X family of the distribution known as double-Exponential-Pareto distribution was used to fit a real life data on the use of antiretroviral drugs. Molecular simulation of efficacy of antiretroviral drugs is conducted to evaluate the performance of the model. The models were tested using some models diagnostic tests and it was revealed that the proposed model was better than the ones proposed before it from the same family and also, stochastic dominance method was used to affirm the best antiretroviral drugs used in the study.

The substrate's nature plays an important role in the characteristics of semiconductor films because of the thermal and lattice mismatching between the film and the substrate. In this study, tin sulfide (SnS) nanostructured thin films were grown on different substrates (polyester, glass, and silicon) using a simple and low-cost chemical bath deposition technique. The structural, morphological, and optical properties of the grown thin films were investigated using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and ultraviolet-visible-near infrared (UV-Vis-NIR) spectroscopy. The XRD and FESEM results of the prepared films revealed that each film is polycrystalline and exhibits both orthorhombic and cubic structure types. In addition, the deposited films on polyester and glass showed good absorption in the UV-Vis-NIR range.

Non-alcoholic fatty liver disease (NAFLD) is one of chronic liver and defines by fat accumulation ≥5% in liver which can progresses to non-alcoholic steatohepatitis (NASH). NAFLD related to obesity as well as non obese individuals. Adiponectin is a cytokine secreted from adipose tissue involved NAFLD pathogenesis and liked with obesity. Irisin is a myokine, has a convenient effect against metabolic diseases such as obesity, disylipemia diabetes type 2 and reversed liver steatosis and may be related with NAFLD.  Vitamin D is one of the fat soluble vitamins and more precisely as a pro-hormone through its metabolite (1,25(OH)2 cholecalciferol) the major steroid hormone. After the skin exposure to the light, vitamin D undergoes to activation through two successive hydroxylation reactions in liver and kidney. Several metabolic diseases such as dyslipidaemia, obesity, hypertension, T2D and metabolic syndrome (MS) have been related to vitamin D deficiency.  
非酒精性脂肪性肝病(NAFLD)是一种慢性肝脏疾病,定义为肝脏脂肪堆积≥5%,可发展为非酒精性脂肪性肝炎(NASH)。NAFLD与肥胖和非肥胖个体有关。脂联素是一种由脂肪组织分泌的细胞因子,参与NAFLD的发病机制,并与肥胖有关。鸢尾素是一种肌因子,对代谢性疾病如肥胖、二脂血症、2型糖尿病和逆转肝脂肪变性等有方便的作用,可能与NAFLD有关。维生素D是一种脂溶性维生素,更准确地说,它是一种促激素,通过它的代谢物(1,25(OH)2胆钙化醇),一种主要的类固醇激素。皮肤暴露在阳光下后,维生素D在肝脏和肾脏中通过两个连续的羟基化反应被激活。一些代谢性疾病,如血脂异常、肥胖、高血压、T2D和代谢综合征(MS)都与维生素D缺乏有关。

The goal of this study is to provide a new explicit iterative process method  approach for solving maximal monotone(M.M )operators in Hilbert spaces utilizing a finite family of different types of  mappings as( nonexpansive mappings,resolvent mappings and projection mappings. The findings given in this research strengthen and extend key previous findings in the literature. Then, utilizing various structural conditions in Hilbert space and variational inequality problems, we examine the strong convergence to nearest point projection for these explicit iterative process methods Under the presence of two important conditions for convergence, namely closure and convexity. The findings reported in this research strengthen and extend key previous findings from the literature
