One of the ways to improve the fusion of an implant with bone tissue is through the use of biocompatible coatings, in particular, hydroxyapatite (HAp). It is important to assess the strength of the HAp adhesion to the implant. The measure of the strength of the bond of the coating with the substrate is the energy of this bond. Using density functional theory and molecular dynamics, the reaction path, reaction products, oscillation frequency, activation energy and bond energy between different combinations of compon [...]

Waste-to-Energy technologies have the potential to dramatically improve both the natural and human environment. One type of waste-to-energy technology that has been successful is gasification. There are numerous types of gasification processes and in order to drive understanding and the optimization of these systems, traditional approaches like computational fluid dynamics software have been utilized to model these systems. The modern advent of machine learning models has allowed for accurate and computationally ef [...]

Improved understanding of the underlying cellular dysfunction and resultant neuropathology of sporadic Alzheimer’s disease (AD) is needed to stem the anticipated public health crisis due to this increasingly common neurodegenerative disease. The four main risk factors for sporadic AD are age, female gender, genetic carriage of the APOE4 allele and type two diabetes mellitus (T2DM). Each of these four risk factors is associated with impaired and/or dysfunctional autophagy suggesting that perturbation of autophagy is [...]

This paper sets out a quantified scenario for the UK to reach net zero carbon emissions. Wind and solar are the main energy sources and their intermittency is accommodated through hydrogen electrolysis, biogas from anaerobic digesters, and their combination into biomethane. Hydrogen and biomethane stocks are tracked. A daily energy balance model is presented, using the most recent recorded weather data-2017 to 2021. Long periods of low wind in 2021 indicated the necessary energy storage capacities, which were adjus [...]

Towards the end of 2019, an unanticipated outbreak, coronavirus also referred to as COVID-19’s first cases occurred in Wuhan City, Hubei Province, China. In early 2020, the World Health Organization (WHO) declared the pandemic as a Public Health emergency of international concern. COVID-19 is a transmissible disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 puts a spotlight on numerous issues varying from educational, social, political, and economic that were already prese [...]

Waste marble powder (WMP) is Investigated for developing heterogeneous catalysts by calcination method and used in biodiesel synthesis by esterification-transesterification process from Pongamia Pinnata oil. Hammet indicators, Fourier transform infrared (FT-IR), Thermogravimetric analysis, and X-ray powder diffraction (XRD) techniques were also studied for the characterization of developed catalyst from waste marble powder (WMP). The conversion of calcium carbonate to calcium oxide in marble powder was found at 800 [...]

This study integrated functional connectivity measures using resting-state fMRI and behavioral data from a single-case observation of patient (PER) one year after right-hemispheric hemorrhage in the intraparietal sulcus and superior parietal lobule (IPS/SPL). PER showed no sign of clinical neglect. Her behavioral performance in the visuo-manual pointing task and in the letter discrimination task under conditions of endogenous and exogenous attentional cueing was compared between the left (affected) and right (unaff [...]

Lung transplant recipients represent a high-risk group for cytomegalovirus (CMV) infection and disease, even among solid organ transplant (SOT) recipients, due to multiple factors. Additionally, CMV has significant consequences in this group including pneumonitis, acute rejection, and chronic lung allograft dysfunction. For the past two plus decades, treatment of CMV in SOT recipients has been limited to off-label use of 4 antiviral medications associated with significant toxicities including myelosuppression and n [...]

Bacteriophages, or phages, are viruses that infect bacteria, exhibiting specificity towards particular bacterial strains. Despite being overshadowed by traditional antibiotics in the West, interest in phage therapy has resurged due to the escalating antimicrobial resistance crisis. Understanding phage biology, selection, production, and pharmacology is crucial for their clinical application. Phages interact intricately with the human microbiome, influencing bacterial populations and potentially offering therapeutic [...]
