Multiscale models combining quantum mechanical and classical descriptions are a very popular strategy to simulate properties and processes of complex systems. Many alternative formulations have been developed, and they are now available in all of the most widely used quantum chemistry packages. Their application to the study of light-driven processes, however, is more recent, and some methodological and numerical problems have yet to be solved. This is especially the case for the polarizable formulation of these models, the recent advances in which we review here. Specifically, we identify and describe the most important specificities that the polarizable formulation introduces into both the simulation of excited-state dynamics and the modeling of excitation energy and electron transfer processes.Purpose The purpose of this introduction is to briefly describe the nature of the conference, Aging and Speech Communication An International and Interdisciplinary Research Conference, and to introduce the articles featured in this forum that represent the nature of the biennial conference.Purpose The aim of this study was to evaluate literature on auditory training published since 2013. Method A rapid review or a streamlined approach to systematically identify and summarize relevant studies was performed. Selected health sciences databases were searched using a search strategy developed with the PICO (population, intervention, comparison, and outcome) framework. Studies eligible for inclusion had older adult participants with hearing loss and utilized technology-based auditory training in laboratory or home settings. Results The study quality of most studies was found to be low to moderate, with concentrations between low and moderate. Major issues were related to study design and reporting, such as the need for blinding and a control group, larger sample sizes, and a follow-up for long-term outcomes of auditory training interventions. Wide variability in training approaches, participant backgrounds (e.g., audiograms, hearing aid use), and outcome measures are also noted. Conclusions Evidence on the effectiveness of auditory training is mixed. Future research should include high-quality randomized controlled trials with representative populations; follow-up periods to study long-term effects; and exploration of behavioral, electrophysiological, and self-reported outcome measures. Recommendations for study designs and methodologies are also discussed.In the modern age, the struggle to generate appropriate bio-based materials and nano-scaled colloidal particulates for developed application domains, has already resulted in remarkable attempts in the advancement of regulated size and shape, anisotropy, and characteristics of nanostructures. The bottom-up development strategies of components are among the most important science areas throughout nanotechnology, in which the designed building blocks are often utilized to generate novel structures by random self-assembly. In biomedical applications, Janus nanoparticles (JNPs) are necessary. This is due to their effective stimulus-responsive properties, tunable structure, biocompatibility, containing two surfaces with various hydrophobic characteristics and distinct functional groups. Featuring two parts with differing hydrophobicity has been the most critical aspect of the Janus amphiphilic particles. Development of JNPs has been afforded, using imaging agents (e.g. gold (AU) for photoacoustic imaging processing (PAI), silver for surface-enhanced Raman scattering (SERS), and Fe3O4 and MnO2 to magnetic resonance imaging (MRI)). It is also to be mentioned that a number of other properties become salient - properties such as integration imaging factors into JNPs (like quantum dots, fluorescent dyes), multiple imaging methods for screening and diagnosis application can indeed be accomplished. Janus nanostructures have been promising platforms for bioengineering as therapeutic carriers, drug delivery vehicles, and biosensor equipment; they may also be employed for the transport of bioactive hydrophilic and hydrophobic materials. The main production approaches and major advancement of JNPs in the biomedical sector and cancer therapy will be described in this paper.In the present study, Mentha plant ash was modified by Na and Al for the synthesis of adsorbent and applied for the removal of Fluoride from an aqueous solution. Mixture of acid washed Mentha plant ash (MPA) and NaOH (in the ratio 11.3) thermally treated at 600°C in a muffle furnace then treated with aqueous solution of sodium aluminate. The characterization of sodium aluminum modified ash (Na-Al-MA) powder was done such as SEM (Scanning Electron Microscopy), Particle Size Analysis (PSA), Fourier transformed spectroscopy (FTIR), Zeta Potential, XRD (X-ray Diffraction) analysis, and Brunauer-Emmett-Teller (BET) analysis. The removal of fluoride from an aqueous solution carried out with Na-Al-MA by batch adsorption process. The Na-Al-MA was found to be very effective as adsorbent. The maximum removal of fluoride was achieved ̴ 86% at neutral pH and at room temperature. It was investigated that Langmuir adsorption isotherm and pseudo-second-order kinetic was best fitted for fluoride adsorption. The fluoride adsorption on Na-Al-MA was an exothermic process.  https://www.selleckchem.com/products/bevacizumab.html  A possible mechanism including electrostatic attraction, hydrogen bonding, and metal-fluoride interaction for fluoride adsorption on Na-Al-MA have described in this study. Novelty statement Utilization of Mentha plant ash for the development of adsorbent and its application in adsorptive removal of fluoride from aqueous solution is the novelty of this work. Adsorbent preparation may be the better way of waste biomass management.
  The high prevalence of peripartum depression (PPD) among mothers of preterm infants concerns health professionals due to its implications for mothers' and infants' health. A model for explaining PPD, consisting of four personal resources was examined locus of control, intolerance to uncertainty, maternal self-efficacy, and quality of the couple relationship.
 
  In one of the largest Neonatal Intensive Care Unit (NICU) in Israel, 129 mothers of 215 preterm infants completed self-report questionnaires regarding their background variables, locus of control, intolerance to uncertainty, maternal self-efficacy and quality of couple relationship.
 
  PPD symptoms and high risk for diagnosing clinical PPD.
 
  The examined personal resources explained 43.9% of the variance in PPD symptoms. Intolerance to uncertainty was positively associated with PPD symptoms, while internal locus of control, high levels of maternal self-efficacy, and high quality of couple relationships were found to be negatively associated with PPD symptoms.
