Cervical cancer is an intrusive cancer that imitates various women around the world. Cervical cancer ranks in thefourth position because of the leading death cause in its premature stages. The cervix which is the lower end of thevagina that connects the uterus and vagina forms a cancerous tumor very slowly. This pre-mature cancerous tumorin the cervix is deadly if it cannot be detected in the early stages. So, in this delineated study, the proposed approachuses federated machine learning with numerous machine learning solvers for the prediction of cervical cancer totrain the weights with varying neurons empowered fuzzed techniques to align the neurons, Internet of MedicalThings (IoMT) to fetch data and blockchain technology for data privacy and models protection from hazardousattacks. The proposed approach achieves the highest cervical cancer prediction accuracy of 99.26% and a 0.74%misprediction rate. So, the proposed approach shows the best prediction results of cervical cancer in its early stageswith the help of patient clinical records, and all medical professionals will get beneficial diagnosing approachesfrom this study and detect cervical cancer in its early stages which reduce the overall death ratio of women due tocervical cancer.

Identifying deformational mechanisms and associated structures at various scales, ranging from regional-scale structures to microscopic fabric, is crucial for the assessment of tectonic development. Thirty-three samples were taken from the Qazzaz metamorphic core complex to estimate the finite strain for felsic and mafic minerals. These samples included gneisses rocks, monzogranite, and metavolcano–sedimentary rocks for both the Thalbah and Bayda groups. Using the Rf/j and Fry methods, the axial ratios(XZ) range about 2.20 to 7.10 and 1.90 to 9.10, respectively. For various rock units, the strain measurements show moderate to highly deformation. Most of the observed samples show shallow WNW dipping along a N to WNW trend of finite strain(X). The short axes(Z) based to be subvertical foliation related with a subhorizontal foliation. The results demonstrate that contacts generated at semi-brittle to ductile deformation and that the strain of magnitude has the same value for different lithologic units. It concluded that nappe generation in orogens results from pure shear deformation.

Takotsubo cardiomyopathy is a heart condition that is widely known to be caused by stress. It presents with symptoms that are similar to a myocardial infarction even though the coronary arteries are clear. This case report details the clinical characteristics, diagnostic assessment, and management plan of a 55-year-old male patient with a past medical history of alcoholism who arrived at the emergency department with the typical symptoms of acute pancreatitis. The case demonstrates the progression of Takotsubo cardiomyopathy, which was triggered by acute pancreatitis in the context of alcoholism, and underlines the significance of early detection and management to enhance the patient’s outcomes.

A series of CuO-K2Mo4013 composite materials have been prepared by mixing appropriates quantities, in solid state, of CuO and pure K2Mo4013 according to the molar ratios CuO/K2Mo4013 = 0.05, 0.1, 0.2, 0.5, and 1. The prepared samples were characterized using techniques such as X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FT-IR）, differential thermal analysis （DTA）, nitrogen adsorption measurements, and UV spectroscopy. According to XRD results, the phase composition of the CuO-KeMo4013 systems has significantly changed by increasing the molar ratio CuO/ K2Mo4013 where new phases, identified as K2Mo3Olo and CuMoO4, have been detected. The formation of these new phases has been tracked through FT-IR and DTA measurements. The nitrogen adsorption-desorption measurements also reveal a change in the pore type of the studied materials due to the presence of these new phases. The photocatalytic activities of K2M04OI3 and CuO-K2Mo4013 composites were studied by means of monitoring the ability of these materials to the degradation, under UV irradiation, of methyl red in liquid media. It was found that the phase composition of the used samples significantly controls their photocatalytic activities.
