This paper presents a new method for separating Rhenium, Molybdenum, Vanadium and Tungsten ions on a thin layer of Perlite using the thin layer -electro-chromatography method. This method is based on the combination between chromatographic forces and electric forces by applying different voltages on the separation plate for different times using several electrolytes as different mobile phase concentrations, at different applying field duarations on the process. This method also shows the possibility of using Perlite as a thin layer in this kind of separation process, which can apply in the separation of other types of biochemistry and inorganic ions This relatively simple method is cost effective.

Journal of Chemical and Pharmaceutical SciencesAnthocyanin pigments: Structure and biological importance
Anthocyanins are coloured water-soluble pigments representing one of the major subclasses of compounds. They rarely exist in nature as free aglycons, instead, they attach to one or more sugar moieties. Anthocyanins are found within different plant organs; flowers, leaves, fruits, roots, tubers and grains. They appear in different attractive colours depending on their structure, pH, and other factors. These compounds gained a lot of attention in the last few years as food colourants replacing chemical dyes, besides their role in enhancing plant tolerance against many abiotic stresses such as salinity, drought, excessive light, ultraviolet radiation and cold stress. Besides, previous studies demonstrated the importance of anthocyanins in human health and their protective properties against chronic diseases.

WORLD JOURNAL OF PHARMACEUTICAL AND MEDICAL RESEARCHMonkeypox: Facts about the Disease
Monkeypox is a zoonotic disease caused by the monkeypox virus of the genus Orthopoxvirus genus and Poxiviridae family. Many animal species, including rodents and monkeys, can transmit the virus. However, the natural reservoir is unknown yet. It can be transmitted to humans via close contact with infected animal or person, or contaminated materials. Monkeypox virus was first detected in 1958 among cynomolgus monkey’s colony in Denmark. The first human case of monkeypox was reported in September 1970 in a 9-month-old child with smallpox-like vesicular skin lesions. This virus usually affects humans and animals living in Central and West Africa, yet it led to several outbreaks previously out of Africa since its discovery. Since 7 May 2022, monkeypox started to appear again in non-endemic countries. By 29 July 2022 at 9:00 PM (GMT), 22485 confirmed cases were recorded worldwide. This review

ScienceDirectBiomechanical Assessment of the Influence of Inlay/Onlay Design and Material on Stress Distribution in Nonvital Molars
Objectives The aim of this study was to evaluate the influence of inlays/onlays with or without pulp extension from different materials on stress distribution in endodontically treated molars by three-dimensional finite element analysis (3D FEA).
Materials and Methods We used 3D mandibular molar models in this study. The models represented mesio-occluso-distal (MOD) cavities restored by inlays, onlays that covered buccal cusps, and onlays that covered all cusps with pulp extension (modified inlay/onlay) or without pulp extension (conventional inlay/onlay). Three materials (L: lithium disilicate glass-ceramic, P: polymer-infiltrated ceramic network [PICN], and C: nanofilled composite resin) were utilized. A force of 600 N was applied vertically and obliquely. Stress distribution in FEA models was analyzed using the von Mises theory.
European Journal of General DentistryNumerical Modeling of Renal Ionic Equilibrium for Implantable Kidney Applications
The human kidney is one of the most important organs in the human body; it performs many functions and has a great impact on the work of the rest of the organs. Among the most important possible treatments is dialysis, which works as an external artificial kidney, and several studies have worked to enhance the mechanism of dialysate flow and improve the permeability of its membrane. This study introduces a new numerical model based on previous research discussing the variations in the concentrations of sodium, potassium, and urea in the extracellular area in the blood during hemodialysis. We simulated the differential equations related to mass transfer diffusion and we developed the model in MATLAB Simulink environment. A value of 700 was appeared to be the most appropriate as a mass transfer coefficient leading to the best permeability. The suggested models enabled to track the temporal variations of urine, K and Na concentrations in blood streamline.

The restorations were: inlay, onlay that covered buccal cusps (B models), and onlay that covered all cusps (LB models). Inlays and onlays were represented by two materials: nanofill composite resin and polymer-infiltrated ceramic network (PICN). Vertical load of 600 N was applied and von Mises stresses were calculated.
Journal of StomatologyThis research aims to develop an Arabic text-to-speech (TTS) service with Syrian dialect, which is a variety of Arabic spoken in Syria and some neighboring countries, with easy access to it for people with disabilities or difficulty reading Arabic, such as people with visual impairments or learning disabilities. To achieve this goal, we employ two state-of-the-art Machine Learning (ML) approaches: Tactron2 and Transformers, which have achieved impressive results in various natural language processing tasks, including TTS. We compared the two approaches and evaluated the resulting TTS service using subjective measures. Our results show that both approaches can produce high-quality speech in the Syrian dialect, but transformers have the advantage of being more efficient and more flexible in handling different languages and accents.
