Abstract: At present, the calculation of 2nd/3rd/4th degree equations in one variable is complicated, and it is difficult to universally apply. There is no solution for entangled one-variable 5th degree calculus equations. Propose a circle logarithm algorithm: One of the highlights is the integration of discrete data statistics and entangled neural network analysis, and arithmetic analysis is performed between unlabeled circle logarithms {0 to 1}. It involves the foundation of mathematics, the reform of traditional calculus, and the algorithm of a new generation of computer neural networks. Here is a reorganization of the bylaws to solve the complete problem of the 2nd/3rd/4th/5th degree calculus equation, and provide relevant experts, scholars, readers to verify and check the calculation, and it can also be converted into the compilation of new computer programs.

Abstract :There has been a renewed interest in developing more flexible statistical distributions in recent decades. A major milestone in the methods for generating statistical distributions is undoubtedly the system of differential equation approach. There is a recent renewed interest in generating skewed distributions. In this research, a new four parameter lifetime distribution which extends the Lomax distribution is introduced by compounding the Lomax distribution with the complementary generalized transmuted Poisson family of distributions. The probability density function and cumulative distribution function as well as some basic statistical properties of the new distribution, such as moments, reliability function, hazard function, quantile function, residual life function, entropy and the order statistics were derived. Some plots of the distribution shows that it is a positively skewed distribution. The maximum likelihood estimation method is used to estimate the parameters of the new distribution. A simulation study to assess the performance of the parameters of the newly developed distribution was provided with an application to real life data to assess its potentiality. The result shows that the proposed distribution provides better fit than some generalizations of the Lomax.

Abstract:  A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in water body caused by the displacement of aa large volume of water, generally in an ocean or a large lake. Some studies have been conducted by me on the tsunamis  to invent a device  that should be used to study and predict the tsunamies  and designed an architecture named Geoscope in 1987  to keeping the  tsunamis.  Geoscope  is not what Buckminster had proposed in 1962. Let  us study about the exploitation of  tsunamis  and the methods of studying  tsunamis.

Abstract :Background: The metabolic syndrome (Met S) is a cluster of the most dangerous heart attack risk factors as diabetes, abdominal obesity, high cholesterol, and high blood pressure. Protein tyrosine phosphatase 1B (PTP1B), is negatively regulating the leptin and insulin signaling, with positive correlation with adiposity and contributes to insulin resistance. The effect of PTP1B on the obesity is still vague. This study aimed to study the effect of PTPN1 genetic variations (467T>C) on susceptibility to Met S components and its metabolic traits by comparing the PTPN1 gene (467T>C) alleles and genotypes between T2D patients with Met S and healthy Egyptian subjects. Methods: Polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP) analyses were carried out to detect the 467T>C variants of PTPN1 gene in 100 Egyptian patients with obesity as compared to controls (n=80). Results: The results did not detect any significant difference in 467T>C PTPN1 genotypes between patients and control groups (X2= 0.674, P= 0.714). 467T>C PTPN1 variants showed non-significant association with Met S components [diabetic metabolic traits in both groups ; plasma insulin levels, fasting blood glucose levels (FBG) , HOMA-IR , abdominal obesity [Waist circumference (WC) , body mass index (BMI)], the lipid profile parameters , diastolic blood pressure (DBP) and  systolic blood pressure (SBP). Conclusion: The PTPN1 promoter variant of 467T>C was not associated with Met S components and T2D metabolic related traits in Type 2 diabetic Egyptian patients. More studies are required on a larger scale to examine any potential metabolic association.

Abstract :Concrete is known to be the most used construction material worldwide. The environmental and economic aspects of Ordinary Portland Cement (OPC) containing concrete, have led research studies to investigate the possibility of incorporating Supplementary Cementitious Materials (SCMs) in concrete. Metakaolin (MK) is one SCM with high pozzolanic reactivity generated throughout the thermal activation of high purity kaolinite clay at a temperature ranging from 500° C to 800° C. Although many studies have evaluated the effect of MK on mechanical properties of concrete and have reported positive effects, limited articles are considering the effect of MK on durability properties of concrete. Considering the lifetime assessment of concrete structures, the durability of concrete has become of particular interest recently. In the present work, the influences of MK on mechanical and durability properties of concrete mixtures are evaluated. Various experiments such as slump flow test, compressive strength, water permeability, freeze and thaw cycles, rapid chloride penetration and surface resistivity tests were carried out to determine mechanical and durability properties of concretes. Concretes made with the incorporation of MK revealed better mechanical and durability properties compared to control concretes due to combined pozzolanic reactivity and filler effect of MK.

Abstract: QLED TV is a new television technology that is taking many of its cues from OLED TV technology. It consists of extremely small light-emitting crystals called quantum dots. Most TVs today including all of those made by companies and just about every other TV brand are based on decades-old LCD, or liquid crystal display, technology. In the past few years’ Better technology and more advanced manufactured, called OLED or organic light-emitting diode. OLED TVs have the best picture quality we've ever tested, keeping LCD-only companies from achieving the coveted top positions on certain lists. At the moment a new TV display technology on the horizon called QLED, and it might be even better than OLED and LED. Short for "quantum dot light emitting devices," QLED has the potential to match the infinite contrast ratio of OLED, with better power efficiency, better color and more . In this article we will discuss about the QLED and OLED display technology.

Abstract: Study of earthquakes in geological hazards is a key element. Many researches &studies have been conducted by me on the earthquakes to invent a device that should be used to study and predict the earthquakes and also solve the mysteries and other problems of the earth’s underground and designed an architecture named Geoscope in 1987 to keeping the entire earth’s underground to be under control of the geoscope with many revolutionary proposals. This is not what Buckminster had proposed in 1962. My Geoscope was designed to study the earth’s underground mysteries, explore the underground minerals and predict the geological hazards and consisting of revolutionary proposals just like attracting the sea waters to the underground areas of deserts through the layers by electro-ionization and attracting the vaporized sea waters to the desert plains through the sky by geo-magnetizing atmosphere when the weather is surrounded by water molecules during the trough of low pressure areas by constantly studying the underground. Let us, study about the exploitation of earthquakes and the methods of studying earthquakes. Seismic luminescence is one of the key study in earthquakes forecasting methods.

Abstract: Background: Survivin is one of the inhibitors of apoptosis proteins family (IAP) and its expression in keloid was significantly higher than in normal skin tissue. Tacrolimus (FK506) is a calcineurin phosphatase inhibitor inhibits synthesis of inflammatory cytokines produced by T- lymphocytes and induces apoptosis through caspase-3 activation. Intralesional steroid (IL) is a corner stone in keloid treatment. Objectives: To assess survivin level as antiapoptotic factor in keloid and to evaluate the therapeutic effect of topical tacrolimus compared to IL steroid clinically and immunohistochemically. Patient and Methods: fourty keloid patients were included in this study, twenty were treated by intralesional steroid and twenty were treated by topical tacrolimus for three months. Survivin level was estimated in keloid tissue before and after treatment. Results: Our study showed statistically significant higher level in the dermal and epidermal survivin immunoexpression (p-value <0.05) in the keloid tissue as compared to the normal skin tissue. There was a statistically significant decrease (p-value <0.05) in the dermal and epidermal survivin immunoexprssion as well as Vancouvre Scar Scale (VSS) after treatment in both steroid and tacrolimus groups without significant difference between both modalities. Keloid improvement was higher in steroid group (45%) than in tacrolimus group (25%); however, there was no statistically significant difference in keloid improvement between both treatment groups. Conclusion: Survivin plays a role in pathogenesis of keloid. Topical tacrolimus showed therapeutic effect in keloid treatment, however ILsteroid is the corner stone treatment modality of keloid.
