Sleep has played a critical role in maintaining the physical and psychological health of humans, especially for women. Many studies reveal that sleep disturbance can cause more inflammation, coagulation, insulin resistance, and psychosocial distress in women than in men. A lot of medications are used to treat sleep disorders, but they can cause various adverse effects. Photobiomodulation therapy (PBMT) has been proved as a safe and easy-to-use therapy. We propose two methods of affecting the autonomic nervous syste [...]

Continuous fiber reinforced geopolymer matrix composites offer the potential for use in structural applications at temperatures up to 700°C, while enabling the manufacture at temperatures below 100°C. Studies have investigated a variety of high temperature structural fiber reinforcements, including carbon, SiC and Al2O3. While there has been active research into various grades of Al2O3 fibers, SiC is most commonly used for high temperature reinforcement of geopolymers in oxidizing environments. Both familie [...]

In this paper, we continue our previous work by discussing the consequences of curvature in spacetime caused by the presence of mass and the implications of this. We address the question raised by Dirac regarding the impact of a magnetic monopole on the quantum world. We discuss quantization concerning the solid angles observed, which may have a connection with a magnetic monopole.

Hemangioblastomas (HBs) are benign, highly vascularized tumors of the central nervous system. Approximately 75% of HBs are sporadic, while 25% are associated with von Hippel–Lindau (VHL) disease. HBs consist of two main components: a rich capillary network composed of vascular endothelia and pericytes, within large vacuolated stromal cells, which harbor the genetic defect. The mechanism by which the VHL gene product (pVHL) causes HB is not completely clear. Wild-type pVHL is involved in the response to hypoxia, tar [...]

The tribological properties of ZnO thin film coated on an aluminium work piece by RF magnetron sputtering were studied as a function of deposition power, substrate coating temperature, heat treatment and rotation speed. The variation in the coefficient of friction of ZnO films produced under various levels of coating parameters and conditions were experimentally determined using a pin-on-disk tribometer. The results showed that with change in deposition conditions and heat treatment, there are significant microstru [...]

One of the objectives of psychological intervention is to help patients manage their emotions effectively by providing them with the necessary skills to accompany their own emotional states. To this regard, there seems to be a current lack of therapeutic resources aimed at helping patients assimilate and regulate emotions. This article proposes the application of a new technique which incorporates mindfulness, building on the premises of the model of psychological flexibility which defines "mindfulness" as a practi [...]

Background: The majority of long-term care provided to older adults and persons with disabilities is provided by unpaid family caregivers and friends. Employers have a stake in long-term care services as well since 60% of caregivers are employed outside the home, 49% have gone in late, left early, or taken time off during the day to deal with caregiving issues, and 15% have taken a prolonged leave of absence. Additionally, 87% of employed caregivers make telephone calls for caregiving from work. Presenteeism, the s [...]

The influence of different levels of alkalinity, expressed using M2O-to-binder ratio (n) and activator SiO2-to-M2O ratio (Ms), (M being the Na+ or K+ cation) on the reaction kinetics, compressive strength development and the reaction product formation in slag-based systems activated using alkali powders are discussed. The fundamental idea is to better understand one-part, “just-add-water” type alkali activated binders that are easy-to-use than the systems that rely on liquid activators. The difference in the behavi [...]

Small supernumerary marker chromosomes (sSMCs) are centric chromosome fragments additionally present in an otherwise normal human chromosome set that cannot be characterized by classical cytogenetic techniques alone. The majority of sSMCs are not yet related to a defined clinical phenotype. We compiled from the literature all 78 cases with multiple sSMCs per cell in which the chromosomal origin of the sSMCs has been identified. The number of sSMCs varies from 2 to 7; 64% have 2 sSMCs, 14% have 3 sSMCs, and the freq [...]
