Foam concrete is a promising material in building and construction applications, providing such outstanding properties as high specific strength, excellent thermal insulation, effective acoustic absorption human-inhabited buildings. However, because the porosity permeable water of foam are significantly higher, its durability often not comparable to that ordinary concrete, so requires significa...

Several natural and human factors are responsible for the defacement of external walls tiles buildings, related deterioration can be a public safety hazard. Therefore, active building maintenance repair processes essential ensuring sustainability. However, conventional inspection methods time-, cost-, labor-intensive processes. herein, this study proposes convolutional neural network (CNN) mode...

The phase state of atmospheric aerosols has an impact on their chemical aging and their deliquescence and thus their ability to act as cloud condensation nuclei (CCN). The phase change of particles can be induced by the deliquescence or efflorescence of water or by chemical aging. Existing methods, such as tandem differential mobility analysis rely on the size change of particles related to the...

The durability of precast structures often depends on quality execution the connections between structural elements. Essential also is their design and proper exploitation. This paper focuses magnitude damages as well repair methods used for a slab, which consists prestressed double T slab elements supported inverted girders. It was found that during execution, girders were forced to fit dowel ...

Abstract Around the world, large amounts of plastic and glass waste have been collected. This work is given as a way to reduce this material. paper aims investigate how fired clay bricks' physical mechanical properties are affected by plastic/glass ( P/G) powder. It used replacement for clay, varying content 00/20, 05/15, 10/10, 15/05, 20/00 weight %. The ratio soil water remains constant 0.3. ...

The US federal government has been widely criticized for its response to the Coronavirus/Covid-19 pandemic. Much of poor and outcome ascribed President Trump’s personal failure. Yet more importantly this failure governmental system. More specifically, role in fashioning nationwide policies across a range areas, including public health, crippled by an anti-federalist ideology institutional inert...

En Côte d’Ivoire le concombre qui est un légume renfermant de nombreuses vertus sur plan nutritionnel et sanitaire devenu essentiel dans l’alimentation des citadins. Ce ne fait pas l’objet d’exportation à cause sa production réduite (environ 30000 tonnes) sous la pression ravageurs particulièrement les Lépidoptères. Cette étude a été entreprise pour inventorier décrire dégâts Lépidoptères inféo...

BACKGROUND Chronic recurrent oral aphthous ulcers are the most common type of inflammatory efflorescence of the oral mucosa, with a prevalence of 2% to 10% in Caucasian populations. To treat them properly, physicians should know their clinical appearance and course, conditioning factors, underlying causes, and differential diagnosis. METHOD This review is based on pertinent articles that were...

Computer-based docking screens are now widely used to discover new ligands for targets of known structure; in the last two years alone, the discovery of ligands for more than 20 proteins has been reported. Recently, investigators have also turned to predicting new substrates for enzymes of unknown function, taking docking in a wholly new direction. Increasingly, the hit rates, the true-positive...
