Abstract Eye-based communication languages such as Blink-To-Speak play a key role in expressing the needs and emotions of patients with motor neuron disorders. Most invented eye-based tracking systems are complex not affordable low-income countries. Blink-To-Live is an eye-tracking system based on modified language computer vision for speech impairments. A mobile phone camera tracks patient’s eyes by sending real-time video frames to modules facial landmarks detection, eye identification...

Abstract Background Archaeological limestone artifacts are subject to several deterioration factors that can cause harm while they buried in soil, such as wet salt soil. Thus, one of the biggest challenges is restoring have been discovered from excavations. Understanding nature after extraction and resulting alterations, stone’s structural instability high content artifacts, prerequisites for restorer. In 1974 AD, King Ramesses III’s gate was excavated ancient Heliopolis Temple Cairo. The...

INTRODUCTION Marjolin's ulcer (MU) is an uncommon malignancy occurring on top of old scars. Once thought to be more common in Caucasians, now detected increasingly Africa. METHODS This was a retrospective study patients with MU attending tertiary centre within Mansoura University (Egypt) from 2004 2015. An institutional-based registry skin and soft-tissue malignancies this period revealed 560 cases, which there were 26 cases MU. RESULTS The most underlying cause burns (92% patients),...
In recent years there has been a great deal of interest and support worldwide in using construction demolition waste as ceramic well clay brick wastes (grog) for production aggregate material which can then be reused road base courses or backfill materials, other engineering applications. However, they also employed supplementary cementitious materials even raw alkali-activated binder producing more valuable binders that applied various building Geopolymer bricks prepared by partial...
Plasma Pulse Geo Drilling (PPGD) is a contact-less drilling technique, where an electric discharge across rock sample causes the to fracture. Experimental results have shown PPGD operations are successful if certain electrode spacings, pulse voltages, and rise times given. However, underlying physics of breakdown within rock, which cause damage in process, still poorly understood. This study presents novel methodology numerically plasma generation for pulses between 200 500 kV pores with...
Abstract TJ-II stellarator results on modelling and validation of plasma flow asymmetries due to on-surface potential variations, fuelling physics, Alfvén eigenmodes (AEs) control stability, the interplay between turbulence neoclassical (NC) mechanisms liquid metals are reported. Regarding neoclassically predicted asymmetries, its impact radial electric field along flux surface has been successfully validated against Doppler reflectometry measurements. Research physics core with pellets...
Drilling costs can be 80% of geothermal project investment, so decreasing these deep drilling substantially reduces overall costs, contributing to less expensive electricity or heat generation. Plasma Pulse Geo (PPGD) is a contactless technique that uses high-voltage pulses fracture the rock without mechanical abrasion, which may reduce by up 90% conventional rotary costs. However, further development PPGD requires better understanding underlying fundamental physics, specifically dielectric...
Abstract The main results obtained in the TJ-II stellarator last two years are reported. most important topics investigated have been modelling and validation of impurity transport, gyrokinetic simulations, turbulence characterisation, effect magnetic configuration on fuelling with pellet injection, fast particles liquid metal plasma facing components. As regards transport research, a number working lines exploring several recently discovered effects developed: tangential drifts neoclassical...
The construction industry relies heavily on cement and concrete as primary building materials. However, concerns regarding environmental sustainability have prompted efforts to develop more durable sustainable alternatives Ordinary Portland (OPC), the commonly used binder materials with low CO2 emission, where every ton of produce about 0.94 carbon dioxide. present study investigates partial replacement clinker volcanic basalt powder in production eco-friendly emission CO2, addition conserve...

The impact of incorporating synthesized zeolite on Portland cement with different ratios was analyzed to enhance the healing effeciency pre-cracked hardened matrix. specimens subjected treatment through immersion in tap water or a saturated lime solution, objective enhancing effectiveness process. These matrices represent most frequently used environments suitable for crack healing. Given that is crucial component hydration, can alternatively be applied cracks via spraying facilitate ability...
Abstract Background Lung cancer is one of the leading causes cancer-related mortality worldwide. It frequently metastasizes to bone, brain, lung, and liver, causing a shorter survival. Unusual metastasis also occurs. A few reports have been published, majority described metastatic sites involved gastrointestinal system and, occasionally, thyroid gland. Gastrointestinal from primary lung rare; however, tract as an event frequent. However, distant gland rare for all types tumors. Case...
