Cover Story:Skin-sweat-dress hydrodynamic lubrication and tribology is a new scientific domain, where the living human skin lubricated by sweat, co-operates during the motion with the non-living surface of one piece tightly fitting dress material. The sportsman gains additional tangential forces on the skin body on the human limbs, which are steadily distributed on all of the body surface and are going to obtain proper increments efficiency for acrobatic feats.View this paper

Non Solved Contemporary Scientific Problems of Non-Conventional Bio-Surfaces LubricationAbstract This paper presents new non solved, scientific research directions and their applications in contemporary non-conventional lubrication problems of the bio-surfaces domain. Here are described new research scientific trends and research problem solutions of hydrodynamic lubrication for living tissue, human skin and human cartilage joints surfaces. At first in introduction is described the state of the art, a new purpose of anticipate research and the bio-tribology connections with other scientific [...] |
Mechanics of ABS Polymer under Low & Intermediate Strain RatesAbstract Thermoplastics polymers like Acrylonitrile Butadiene Styrene (ABS) are often reinforced with nano/micro reinforcements to enhance their mechanical, thermal and electrical properties. However, the viscoelastic nature of these polymers results in their strong dependence on the applied strain rate and temperature sensitivity, leading to their characterization complexity. Hence it is paramount to study the strain rate-dependent mechanics of neat ABS. In this study, the effect of strain rate and temp [...] |

Accounting for the Influence of Heat-Moisture Treatment Mode When Designing Concrete CompositionAbstract The article proposes a method that considers the parameters of heat and moisture treatment of concrete when designing its composition. Based on the analysis of experimental data, formulas are proposed that allow taking into account the type and characteristics of cement, the characteristics of aggregates, the effect of temperature and duration of steaming, and the water-cement ratio. Graphs and nomograms have been obtained, which makes it possible to simplify the calculation procedure according [...] |
Advances in Quantum Properties of Graphene and Derivatives Applied to Functional Nanomaterials and MetamaterialsAbstract In the present work we describe the most important quantum properties of graphene and derivatives recently published. We discuss how these properties were incorporated into varied hybrid materials such as substrates for specific tuning of matter to track varied quantum signals. Their potential applications were analyzed from nanomaterial and nanotechnology. In particular graphene, its derivatives and other carbon-based allotropes were chosen due to their special chemical structure and properties [...] |
Study of Recycled Spent Coffee Grounds as Aggregates in Cementitious MaterialsAbstract Most spent coffee grounds (SCGs), a byproduct of brewing coffee, are buried in landfill sites, and their decomposition produces significant greenhouse gases. As the recent warming of the Earth’s climate has made it imperative that industries reduce greenhouse gas emissions, the present study investigates the viability of recycling SCGs for use as a partial replacement of aggregates in concrete materials. Cement mortar samples with a fixed cement-to-water ratio and varying amounts of [...] |
Reuse of Sawdust in Developing Countries in the Light of Sustainable Development Goalsby
Udeme Udokpoh
and
Chidozie Nnaji
Abstract The several furniture-making phases, from cutting to processing to polishing, produce a significant volume of sawdust of differing grades. The extraction and disposal of such waste in developing countries with no established or sustainable methods is an increasing problem, frequently posing environmental challenges. Sawdust is one of the most underused wood waste portions, with mounds dispersed around the region, detracting from its visual appeal and causing other ecological concerns [...] |
The Relation between Environmental Risk Analysis and the Use of Nanomaterials in the Built Environment Sector: A Circular Economy PerspectiveAbstract Nowadays, the challenge of climate change and “ecological transition” is substantially an “energy challenge” for every city, which is supposed to become as “energetically self-sufficient” as possible. The construction sector is one of the main contributors to the effects of climate change, starting from the production of materials to the use phase of buildings to their demolition. Recent innovations in sustainable/circular design are related to using “new materials." According t [...] |

Abstract In the context of inspection and maintenance actions for beach walkways in the North of Portugal, some samples of wood used in their construction were collected – the Pinus sylvestris wood, widely applied in the country. The sustainability of the beach walkways over natural coastal areas is very dependent on their material durability. One of the main problems of the timber used to build those structures is its behavior under wet-drying cycles. For that r [...] |
Application of Finite Element Method for Mechanical Characterization of Wood and Reconstituted Lignocellulosic-Based Composites – A ReviewAbstract Performance evaluations of wood and other lignocellulosic-based composites involve complex scenarios of several factors such as material heterogeneity and geometry that often leads to complicated, expensive, and time-consuming experimental procedures. Hence, the application of computational modeling and simulation is desirable to mitigate these biocomposites’ performance testing challenges. This review paper, therefore, presents an outlook on the finite element method (FEM) application in probin [...] |

Retracted: Performance of Grouted Coupler Embedded in Reinforced Concrete ABC Bridge Pier at Vehicle Impactby
Suman Roy
Abstract Increased occurrence of dynamic loading on bridge piers caused by seismic, blast and vehicular impact incidences have been increasingly reported. Statistical data shows that while seismic and blast have received significant attention in the literature, whereas the frequency of occurrence of vehicular impact is remarkably higher but contemplating little consideration. With the newer construction methods like accelerated bridge construction (ABC) and its response against vehicle impact [...] |
