A review on machine learning implementation for predicting and optimizing the mechanical behaviour of laminated fiber-reinforced polymer composites.

The utilization of Machine Learning (ML) techniques in the analysis of the mechanical behavior of fiber-reinforced polymers (FRP) has been increasingly applied in composite materials. The ability to achieve high levels of accuracy, coupled with a reduction in computational cost once the ML models are trained, presents a powerful tool for optimization and in-depth analysis of laminated FRP. This review paper aims to provide insight into the emergence of this trend, offer an overview of various ML algorithms and related subtopics, and demonstrate different implementations of ML from recent studies with a specific focus on the design and optimization of FRP composites.

Bundle care approach to reduce device associated infections in post-living-donor-liver transplantation in a tertiary care hospital, Egypt.

Background: Device-associated infections (DAIs) are a significant cause of morbidity following living donor liver transplantation (LDLT). We aimed to assess the impact of bundled care on reducing rates of device-associated infections.

Methods: We performed a before-and-after comparative study at a liver transplantation facility over a three-year period, spanning from January 2016 to December 2018.

Deformation behavior and properties of severe plastic deformation techniques for bulk materials: A review.

This paper presents a comprehensive review of the successful application of Severe Plastic Deformation (SPD) in producing ultra-fine grained (UFG) and nano-structured crystalline bulk materials. SPD achieves outstanding grain refinement without significantly altering the original dimensions of the workpiece, making it particularly useful for ductile materials that can withstand large strains under high hydrostatic pressure before failure. The study explores the grain refining mechanism during severe plastic deformation and its impact on the microstructure of metals.

Occult HCV infection in liver transplanted patients: frequency and consequences.

Aim Of The Study: Occult hepatitis C virus (HCV) infection (OCI) is a potential source of relapse after liver transplantation with subsequent graft damage. The aim of the study was to detect OCI in patients with living donor liver transplantation (LDLT) who achieved sustained virological response (SVR) after sofosbuvir-based antiviral treatment, and to detect risk factors associated with the development of OCI as well as to determine the effect of direct acting antiviral (DAA) therapy after liver transplantation.

Material And Methods: 41 patients with living donor liver transplantation who did not receive DAAs before with recurrent HCV infection who achieved a SVR with sofosbuvir-based therapy for 12-24 weeks were recruited.

Efficacy of combined Sofosbuvir and Daclatasvir in the treatment of COVID-19 patients with pneumonia: a multicenter Egyptian study.

Background: Limited experimental and clinical evidence suggests a potential role for sofosbuvir/daclatasvir in treating COVID19. We aim to evaluate the efficacy of generic sofosbuvir/daclatasvir in treating COVID-19 patients with pneumonia.

Research Design And Methods: This multicenter prospective study involved 174 patients with COVID-19.

Persistent hiccup: A rare presentation of COVID-19.

Background: Hiccups are involuntary diaphragmatic muscle contractions with early glottis closure terminating inspiration. They are classified into two types: acute (<48 hours) and persistent (>48 hours). COVID-19 is the defining health crisis of our generation.

Experimental and statistical study of the effect of temperature and waste ratio on the mechanical properties and cost of polystyrene polypropylene plastic blends.

Since most plastics are not biodegradable, plastic recycling is the main part of global efforts to reduce plastic in the waste stream. Sorting of plastics imposes lots of difficulties which can be avoided by introducing plastic blends. This paper starts by reviewing the recent attempts to study plastic blends.

Improvement of liver stiffness measurement, acoustic radiation force impulse measurements, and noninvasive fibrosis markers after direct-acting antivirals for hepatitis C virus G4 recurrence post living donor liver transplantation: Egyptian cohort.

Progression of recurrent hepatitis C is accelerated in liver transplant (LT) recipients. Direct-acting antivirals (DAAs) have recently emerged as a promising therapeutic regimen for the treatment of hepatitis C virus infection. Rates of sustained virological response (SVR) have drastically improved since the introduction of DAAs.

Limitations of Living Donor Liver Transplantation in Egyptian Children.

Background/aims: In Egypt, the liver transplantation (LTx) program that became available since 2001 is a living donor program. We aimed to assess the obstacles to pediatric LTx.

Methods: Over a six-month-period, 41 pediatric patients were indicated for LTx; their ages ranged between 1.

Pneumatosis intestinalis following pediatric live-related liver transplant: a case report and successful conservative approach.

PI has been rarely reported following pediatric live-related liver transplantation. Such a disorder is characterized by accumulation of gas in the bowel wall. The cause of PI has not been yet established; however, it has been strongly linked with steroid therapy.

Tension and fatigue behavior of 316LVM 1x7 multi-strand cables used as implantable electrodes.

The mechanical behavior of 316LVM 1x7 cables were evaluated in uniaxial tension, and in cyclic strain-controlled fatigue with the use of a Flex tester operated to provide fully reversed bending fatigue. The magnitude of cyclic strains imparted to each cable tested was controlled via the use of different diameter mandrels. Smaller diameter mandrels produced higher values of cyclic strain and lower fatigue life.
