Background: HIV is a virus that is directed at destroying the human immune system thereby exposing the human body to the risk of been affected by other common illnesses and if it is not treated, it generates a more chronic illness called AIDS. Materials and Methods: In this paper, we employed the fixed-point theory in developing the uniqueness and ...
Materials with excellent moisture buffering performances have considerable application potential in the future developments of building moisture design. The appropriate application of building materials is determined via the effective assessment of their hygroscopic performance, however, currently available test methods (e.g., moisture buffer value...

Numerical simulations for sonochemistry are reviewed including single-bubble sonochemistry, influence of ultrasonic frequency and bubble size, acoustic field, and sonochemical synthesis of nanoparticles. The theoretical model of bubble dynamics including the effect of non-equilibrium chemical reactions inside a bubble has been validated from the st...

The transport of artificial microswimmers is an active research field due to their unique advantages in biological and medical applications, such as drug delivery, surgery, biosensing, minimally invasive medicine, particle separation and environmental treatment. Dynamic magnetic fields, for instance, rotating and oscillating magnetic fields, are of...

CO2–basalt–water interaction safely converts CO2 into carbonate minerals within a short period, which has been verified by the CarbFix project in Iceland. However, the neo-formed secondary silicates as well as carbonate readily fill the fluid paths in the basalt, preventing the CO2 from passing through the rocks, thereby greatly reducing the storag...

The excavation of a tunnel using a shield machine induces an impact on the tunnel lining responses and settlements. Three-dimensional finite difference calculations of twin horizontal tunnels are proposed in this study to investigate the influence of the shield machine’s performance parameters, that is, support pressure at tunnel face, grouting pre...

In order to make a reasonable evaluation of the effect of backfill mining on non-coal mines, the first phase of the Laixin iron ore mine project is taken as an example. First, a geomechanical model of iron ore mining was established according to geological theory; second, numerical simulation software FLAC3D was used to analyze the surface subsiden...

Holocene is an important period for the evolution of human civilization and the study of the relationship between climate change and the development of human society. In the Asian monsoon region, monsoon climate change is an important factor affecting social culture and the change of historical dynasties. Therefore, the evolution of Holocene East A...

These recommendations have been prepared by the corresponding working group within RILEM TC 287-CCS “Early-age and long-term crack width analysis in RC structures”, following work by the previously ceased RILEM TC 254-CMS “Thermal cracking of massive concrete structures”. This recommendations document is developed in complementarity to the state-of...

In the context of laser-based additive manufacturing, the thermal behavior of the substrate is relevant to define process parameters vis-à-vis piece quality. The existing literature focuses on two process variables: (a) lumped laser power and (b) process speed. However, this literature does not consider other variables, such as those related to the...
