This work describes the catalytic performances of attapulgite/ZSM-5 extrudate in comparison to conventional alumina-bound ZSM-5 extrudate in toluene methylation. The novel attapulgite/ZSM-5 extrudate is prepared by using natural clay attapulgite as binder which introduces mobile alkaline species and macropores to the extrudate. In contrast to alumina-bound extrudate, this novel extrudate shows significantly higher para-selectivity and stability. By using characterization techniques, including in-situ XRD, SEM, NH3 temperature programmed desorption (TPD), thermogravimetric analysis and n-hexane/cyclohexane physical adsorption, the catalytic performance improvement of attapulgite/ZSM-5 extrudate is correlated with the neutralization of Brønsted acid sites by mobile alkaline species during calcination and reaction process. Moreover, a higher para-selectivity was obtained over attapulgite-bound modified ZSM-5 extrudate. The strategy of extruding ZSM-5 catalysts with attapulgite as binder is facile and universal. Such method paves a new way for preparation of shaped toluene methylation catalyst with enhanced para-selectivity and stability.

This study aimed to examine the physical response of international referees, participating in different levels of world competitions for footballers with cerebral palsy (CP). Thirteen international referees, who officiated 49 matches in the men’s 2022 World Cup (1st to 15th ranked teams) and 2022 World Championships (16th to 30th ranked teams), participated in this study. A cross-sectional design was used to determine the physical responses and compare the 1st and 2nd halves and the performance in the different tournaments, recording physical variables throughout the matches. Significant higher physical responses (p < 0.05; d = 0.50-0.93; moderate to large) were observed in the World Cup in comparison to the World Championship. Overall, high-level tournaments have been shown to elicit more intense physical responses from referees officiating CP football matches compared to lower-level tournaments. For the World Cup, significantly higher number of accelerations (p = 0.01; d = -0.55; moderate) and decelerations (p < 0.01; d = -0.54; moderate) were registered in the 1st half compared to the 2nd half. This information may be useful for the strength and conditioning coaches of referees to plan weekly training sessions more specifically and adjust the periodical training load and post-match recovery protocols.

Introduction: Third molar surgery can cause post-operative complications to the patient due to the presence of wound from the incision. The study aimed to compare marginal flap with para-marginal flap on postoperative complications by the measurements on pre and post-surgical plaque index (PI), bleeding on probing (BoP), maximum opening of the mouth (MOM), pain perception (PP) and post-surgical tumefaction (PT). Methods: In this double-blind randomized clinical trial, 40 patients were recruited and randomly allocated in two groups. In Group 1, third molar extraction was carried out after a marginal flap design was performed, while in group 2 a para-marginal flap was per-formed. Plaque Index, Bleeding on Probing, Maximum Mouth Opening, and Distal Probing were assessed right before and one week after surgery, while Post-operative Pain Perception and Post-operative Swelling were accounted one week following sur-gery. Results: Statistically significant difference are reported between treatment groups, as the para-marginal flap led to better outcomes for all the measured indexes. Conclusion: The para-marginal flap design may decrease the occurrence of post-operative compli-cations and discomforts after mandibular third molar surgery, compared to marginal flap design.

It is introduced and studied para-Ricci-like solitons with potential Reeb vector field on almost paracontact almost paracomplex Riemannian manifolds. The special cases of para-Einstein-like, para-Sasaki-like and having a torse-forming Reeb vector field have been considered. It is proved a necessary and sufficient condition the manifold to admit a para-Ricci-like soliton which is the structure to be para-Einstein-like. Explicit examples are provided in support of the proven statements.

The self-organization properties of C70 fullerene molecules in a xylene/tetrahydrofuran binary mixture were studied for the first time by optical absorption, refractometry, and dynamic light scattering. A correlation has been established between the change in the refractive index of the C70/xylene/tetrahydrofuran solution and the degree of self-organization of C70 molecules in the medium at various concentrations and storage periods of the solution. It is shown that the features of the optical absorption spectrum of C70/xylene/tetrahydrofuran at a fixed low concentration of the fullerene are sensitive to its storage time. It was determined that the beginning time of the formation of C70 nanoclusters and their final size depend on the concentration of fullerene and the time of keeping the solution. The observed nature of the C70 fullerene solution in a binary mixture may help to elucidate the mechanism of self-organization in the future.

Social safety, security, and comfort of school-going children during the travel time to school becomes a subject of anxiety to the parents and is a crucial issue in recent times. In this regard, community-based transport can be a significant way to address social security issues in travel at a reasonable cost and reduce the burden on private mode. In Dhaka city, school van service already exists but due to some sort of problems the service has not been proved an efficient and formal mode of transport for solving mobility problems. This study seeks to identify the existing problems and prospects of the school van service and provide a unique, healthy, safe, and reliable transport mode for children. Applying different tools of the Participatory Rural Appraisal (PRA) method, the problems and solutions have been drawn from the community. The recommendations of this study will help the school van services (a community-managed para-transit system) to be more functional in playing a vital role in solving the problems of short-distance travel. This service has great potentialities to be adopted in other trips such as trips to and from offices which will lessen the road congestion at the peak periods.

The solute carrier family 25 (SLC25) participates in the transport of metabolites and cofactors across the membranes of mitochondria, plastids, peroxisomes, and endoplasmic reticulum. By calling for genomic blocks involved in adjacent metabolic reactions, this report introduces gene clusters of the Slc25 subfamily 44, stilbene and chalcone synthases, and subunits of the mitochondrial electron transfer complexes. The Slc25A44 gene was found ubiquitously expressed and transcriptionally co-regulated with energy metabolism genes in human, mouse, and Arabidopsis thaliana. The Slc25A44s also had no homozygous missense mutation and were highly conserved at intra-species level with the majority of polymorphism present in the non-coding regions. When expressed in oocytes, AdSlc25A44 from Arachis duranensis showed transport activity for the common precursors of flavonoids, stilbenoids, and ubiquinone. Accordingly, AdSLC25A44 and its human orthologue HsSLC25A44 elevated the production of para-coumaric, 4-aminobenzoic, and 4-hydroxybenzoic acids in Saccharomyces cerevisiae strains designed to produce para-coumaric acid via different pathways. Moreover, the engineered SLC25 subfamily specific signature, i.e., AdSLC25A44^LWW206IQF, had a stronger effect on para-coumaric acid secretion than the native variant. Importantly, the aerobic growth-rate of S. cerevisiae was significantly higher when expressing the AdSLC25A44, HsSLC25A44, or AdSLC25A44^LWW206IQF. These results suggest that SLC25A44 is an essential mitochondrion-ER-nucleus zone transporter associated with metabolism of secondary metabolites and energy.
