Authors: Nagorniy A. 
Published: January 2023

The most widely used in construction materials industry are ceramic and lime bricks. Higher energy consumption and several ecological problems make their manufacture to become more and more expensive. The growing market of construction works and constant extension of real estate property increases the demand for cheap and new materials with desired features.
As a result of many years intensive scientific researches there is now a practical possibility to offer an alternative and unique sand and water based products technology of manufacture (bricks, wall, floor and roofing tiles, sanitary materials, heat insulating and acid proof materials, decorations etc.) – all of them of desired size, shape and colour.
The experience of the structural materials technology development shows that building industry will obtain improved service life and performance from quartz sand suspensions as field installations will continue to move toward adopting and utilizing practices based on technology described herein, rather than on cement technology.
This type of manufacture is very profitable for the countries having the deposits of sand everywhere situated and being extracted at very low prices.
Relative to conventional construction materials sand and water made products (SWP) with mechano-chemical binders will continue to gain in popularity because of the following advantages: low energy consumption and low prices for the products; ecological safety of the manufacture process and of the ready-made products; good mechanical and design properties; moisture and cold proofness; surface need not be fired; no shrinkage of the products after drying; simple to manufacture a variety of different products; ready availability and flexibility in design; absence of manufacture wastes.
METHODOLOGY FOR CONDUCTING AN EXPERIMENTAL STUDY TO RESTORE THE CHARACTERISTICS OF PYROXYLIN POWDERS
Authors: Baulin D. 
Published: January 2023

One of the components of the problem of national security of Ukraine is the loading of warehouses with ammunition with an exhausted warranty period.
Experience in the operation of ammunition shows that during long-term storage, pyroxylin powders used in ammunition are capable of spontaneously undergoing various physical and chemical transformations, which negatively affects the ballistic characteristics of ammunition. The lack of production of ammunition in Ukraine has led to the fact that ammunition is currently in operation, the storage time of which is more than 30 years.
This article analyzes publications devoted to scientific research related to the problems of safe operation of pyroxylin powders. It is shown that one of the main problems in evaluating the properties of pyroxylin powders is the effective physical and chemical monitoring of their state and the prediction of changes occurring during long periods of operation. The relevance of studies of physical and chemical changes in the process of long-term storage of pyroxylin powders, as well as the determination of the possibility of their recovery and effective further use, is indicated.
Various methods for assessing the chemical resistance of gunpowder and their analysis are given.
A method is proposed for determining changes in the characteristics of pyroxylin powders, as well as a method for conducting an experiment to determine the possibility of regenerating powder charges for long periods of operation by treating them with hydrogen peroxide, and, consequently, changing the energy and ballistic characteristics of gunpowder.
An experimental setup for controlling the calorimetric properties of gunpowder is presented. This experiment is carried out in order to determine the strength of gunpowder based on the balance ratios of the energy of gunpowder. The main balance equation underlying the proposed technique is given.
Based on the results of the experiments, it is supposed to obtain the strength of the gunpowder processed according to the developed method, and corresponding to the storage life of the powder charge of ammunition.
It has been determined that on the basis of solving the problem of long-term nitrocellulose powders, theoretical and methodological foundations for the regeneration of powder charges for homologation of the ballistic and energy characteristics of ammunition can be developed.

Habitat and nutrients, but not artificial lighting at night, drive fish assemblage composition in urban streams
Authors: Bohenek Jason , Sulliván S. Mažeika Patricio , Gray Suzanne M. 
Published: January 2023

Abstract
Artificial light at night (ALAN) is pervasive in urban environments, yet its potential effects on biotic communities of urban streams are not fully understood. We investigated the effects of ALAN on fish assemblages in 20 lit-unlit paired stream reaches across 10 sites in Columbus, Ohio, USA across two years. Our results show that light trespass into urban streams is approximately doubled during leaf-off in winter months (1.97 lux ± 0.28) compared to leaf-on in summer months (1.00 lux ± 0.19), highlighting the important interceptive effect of canopy coverage in headwater systems. There were no differences in fish assemblages (i.e., abundance, relative abundance, biomass, diversity, guild composition) between lit and unlit reaches (> 100 m apart). Species richness and α-diversity (Hill numbers) scaled positively with mean stream depth. Nutrient concentrations were negatively related to mean fish mass and fish assemblage diversity. Species richness scaled negatively with total phosphorus and α-diversity scaled negatively with orthophosphate. Our results imply that the relatively low-levels of ALAN observed in canopied streams may exert only subtle effects on small stream fish assemblages, which are difficult to detect amongst the multiple, confounded stressors impacting these relatively species-poor, urban systems. Experimental approaches or large-scale manipulative studies may be necessary to isolate the effects of ALAN on streams and fish in urban contexts.

Published: January 2023

Abstract
BACKGROUND: Pterygium is a common, benign ocular surface disease. Its characteristics, such as hyper-proliferation, anti-apoptotic behavior, and high recurrence rate, contribute to the tumourigenic-like features. Emerging evidence has shown that N6-methyladenosine (m6A) modification plays a vital role in pterygium progression. YTHDF2, an m6A reader, is recognized as promoting targeted mRNA decay. However, the effect of YTHDF2 on pterygium fibroblasts is unknown and remains to be elucidated.
METHODS: 42 pterygium tissues and 42 conjunctiva tissues were obtained from pterygium patients who were recruited from the 2nd Xiangya Hospital. The level of m6A modification was detected using an m6A RNA Methylation Quantification Kit. Quantitative real-time PCR (qRT-PCR) compared the differential expression among binding proteins, methyltransferases, and demethylases. The expression and location of YTHDF2 were identified by immunofluorescence. Plasmid construction, Cell transfection, Western blotting, Cell Counting Kit-8 (CCK-8), and Scratch Wound Healing Assay were used to evaluate the effect of YTHDF2 on proliferation and migration of cultured human pterygium fibroblasts (HPFs). RESULTS: Our research demonstrated that YTHDF2 expression was decreased in HPFs, and overexpression of YTHDF2 could inhibit the proliferation and migration of HPFs. Global m6A expression levels were related to the expression of multiple m6A-related proteins.
CONCLUSIONS: Our study indicated that YTHDF2 might act as a suppressor to suppress the proliferation and migration of fibroblasts in pterygium. This finding provides additional insight into understanding the role of m6A modification in pterygium.

Published: January 2023

Abstract
The first Principle calculations are made to study the structural electronic and optical properties for indium doped aluminum antimonide. The most appropriate method of density functional theory (DFT) naming Full Potential Linearized Augmented Plane Wave (FP-LAPW) is used. The structural properties like Lattice constant (a), pressure derivative, bulk modulus (B) examined by Local density approximation (LDA) along with generalized gradient approximation (GGA). Generalized gradient approximation along with TB-mBJ is used to determine electronic parameters like band structure along and density of states. According to the computed results the binary compound AlSb is optically inactive and exhibits an indirect (Γ -L) band gap. By increasing the concentration of indium with different percentages, the indirect band gape shifted to direct (Γ – Γ) band gap which shows material is optically active. The optical properties of material including dielectric (Real and imaginary part) constant, reflectivity, refractive index, energy loss, absorption coefficient, and optical conductivity have changed significantly. Electronic and optical properties are modified by (TB-mBJ) approach. The results obtained are examined with experimental data and utilized as a starting point to propose that the material is the superlative choice for optoelectronic devices/applications.
Designing for trust: user-friendly refugee wellness center planning process and concept, a health design case study
Authors: Solomon Ellen , Joa Brandon , Coffman Shandon , Faircloth Billie , Altshuler Marc , Ku Bon 
Published: January 2023

Abstract
Background
Refugee and immigrant populations have diverse cultural factors that affect their access to health care and must be considered when building a new clinical space. Health design thinking can help a clinical team evaluate and consolidate these factors while maintaining close contact with architects, patients’ community leaders, and hospital or institutional leadership. A diverse group of clinicians, medical students, community leaders and architects planned a clinic devoted to refugee and immigrant health, a first-of-its-kind for South Philadelphia.
Methods
The planning process and concept design of this wellness center is presented as a design case study to demonstrate how principles and methods of human-centered design were used to create a community clinic. Design thinking begins with empathizing with the end users’ experiences before moving to ideation and prototyping of a solution. These steps were accomplished through focus groups, a design workshop, and iterations of the center’s plan.
Results
Focus groups were thematically analyzed and generated two themes of access and resources and seven culturally specific subthemes that informed the design workshop. A final floor plan of the wellness center was selected, incorporating priorities of all stakeholders and addressing issues of disease prevention, social determinants of health, and lifestyle-related illness that were relevant to the patient population.
Conclusions
Design thinking methods are useful for health care organizations that must adapt to the needs of diverse stakeholders and especially underserved or displaced populations. While much has been written on the theory and stages of design thinking, this study is novel in describing this methodology from the beginning to the end of the process of planning a clinical space with input from the patient population. This study thus serves as a proof of concept of the application of design thinking in planning clinical spaces.

Published: January 2023

Abstract
Background: Venous lakes (VL) are benign malformations often localized in the lips, thereby impacting on the self-confidence of the patients. In the present study, the use of an Nd:YAG laser, according to a defined protocol with an absolute low energy level, is proposed for the treatment of VL of the lips.
Methods: 50 patients with VL of the lips were treated with the Nd:YAG in one laser session, without local anaesthesia. The area reduction, according to the Vlachakis criteria, was evaluated 7 and 30 days after the laser application. Additionally, the oral discomfort, rated according to the Numeric Rating Scale (NRS) during and 24 hours after the procedure, was recorded.
Results: All the patients with VL achieved a complete clinical healing within 30 days after the laser application. In particular, those patients with VL with a diameter ≤ 6 mm (62.1%) achieved a complete resolution after 7 days (p-value: <0.001). Such patients reported no or little discomfort (NRS 0 to 3) during the laser session and no discomfort after 24 hours (p-value < 0.001). No major complications were reported and no recurrence was observed at a 2-year follow up.
Conclusions: These findings suggest that Nd:YAG laser treatment could be an effective and well-tolerated approach in the aesthetic treatment of VL of the lips.
Characterization of Chimeric Antigen Receptor Modified T Cells Expressing scFv-IL-13Rα2 after Radiolabeling with 89Zirconium Oxine for PET Imaging

Published: January 2023

Abstract
Background
Chimeric antigen receptor (CAR) T cell therapy is an exciting cell-based cancer immunotherapy. Unfortunately, CAR-T cell therapy is associated with serious toxicities such as cytokine release syndrome (CRS) and neurotoxicity. The mechanism of these serious adverse events (SAEs) and how homing, distribution and retention of CAR-T cells contribute to toxicities is not fully understood.
Methods
To determine if radiolabelling of CAR-T cells could support positron emission tomography (PET)-based biodistribution studies, we labeled IL-13Rα2 targeting scFv-IL-13Rα2-CAR-T cells (CAR-T cells) with 89Zirconium-oxine (89Zr-oxine), and characterized and compared their product attributes with non-labeled CAR-T cells. The 89Zr-oxine labeling conditions were optimized for incubation time, temperature, and use of serum for labeling. In addition, product attributes of radiolabeled CAR-T cells were studied to assess their overall quality including cell viability, proliferation, phenotype markers of T-cell activation and exhaustion, cytolytic activity and release of interferon-γ upon co-culture with IL-13Rα2 expressing glioma cells.
Results
We observed that radiolabeling of CAR-T cells with 89Zr-oxine is quick, efficient, and radioactivity is retained in the cells for at least 8 days with minimal loss. Also, viability of radiolabeled CAR-T cells was similar to that of unlabeled cells as determined by TUNEL assay and caspase 3/7 enzyme activity assay. Moreover, there were no significant changes in T cell activation (CD24, CD44, CD69 and IFN-γ) or T cell exhaustion(PD-1, LAG-3 and TIM3) markers expression between radiolabeled and unlabeled CAR-T cells. In chemotaxis assays, migratory capability of radiolabeled CAR-T cells to IL-13Rα2Fc was similar to that of non-labeled cells.
Conclusions
Importantly, radiolabeling has minimal impact on biological product attributes including potency of CAR-T cells towards IL-13Rα2 positive tumor cells but not IL-13Rα2 negative cells as measured by cytolytic activity and release of IFN-γ. Thus, IL-13Rα2 targeting CAR-T cells radiolabeled with 89Zr-oxine retain critical product attributes and suggest 89Zr-oxine radiolabeling of CAR-T cells may facilitate biodistribution and tissue trafficking studies in vivo using PET.

Abstract
Corrosion performance of a multi-layered ER316LSi wall deposited using wire and arc additive manufacturing was studied in the as-deposited condition and after stress relief heat treatment at 900 ℃, in 3.5 wt.% NaCl solution. It was found that the heat treatment is not suitable for WAAM ER316LSi components due to the complete transformation of the delta ferrite into sigma decreasing the corrosion performance. The delta ferrite to sigma transformation during heat treatment was facilitated by the cyclic reheating of the part during deposition. The electrochemical response of as-deposited WAAM differed from a wrought alloy with similar composition and linked to microstructural differences: as-deposited WAAM had a higher pitting potential due to the absence of sulfide inclusions and increased metastable activity due to the presence of the secondary delta ferrite causing elemental segregation.

Published: January 2023

Abstract
Management of agricultural waste like rice straw is essential in reducing environmental pollution and also creating added value. For this purpose, microorganisms with high hydrolytic activities were isolated from a simulated composting process. The effects of different materials, including rice straw, chicken manure, urea, olive pomace, and two groups of microbial boosters were assayed at lab-scale and pilot-scale for 60 days. The lab-scale results showed that two treatments containing chicken manure and microbial cocktails (E and F) improved the composting process significantly better than others. They had maximum temperature (59°C), C/N reduction rate (76.7%), and macro/microelements contents. Treatment E showed maximum wheat growth indexes, including dry (1.1 g) and wet (4.7 g) weight of aerial parts, plant height (47 cm), leaf area index (18.9 cm2), and leaf specific area index (45 cm2/g) compared to the control. The pilot-scale results showed that E treatment could reduce C/N (73.48%) better than F (58.32%) and control (13.03%) and it also caused most of the temperature changes up to 69°C. Finally, considering the highest germination index (96%) and lack of phytotoxicity, and also the greatest impact on wheat growth indexes, treatment E was selected for industrial production of compost.

Abstract
Objective
This study aimed to establish an effective ultrasound diagnostic nomogram for benign or malignant lymph nodes in HIV-infected patients.
Methods
The nomogram is based on a retrospective study of 131 HIV-infected patients who underwent ultrasound assess at the Shanghai Public Health Clinical Center from December 2017 to July 2022. The nomogram's predictive accuracy and discriminative ability were determined by concordance index (C-index) and calibration curve analysis. A nomogram combining the lymph node US characteristics were generated based on the multivariate logistic regression results.
Results
Predictors contained in the ultrasound diagnostic nomogram included age (OR 1.044 95%CI: 1.014-1.074 P= 0.004), number of enlarged lymph node regions (OR 5.445 95%CI: 1.139-26.029 P= 0.034), and CDFI grades (OR 9.614 95%CI: 1.889-48.930 P= 0.006). The model displayed good discrimination with a C (ROC) of 0.775 and good calibration.
Conclusions
The proposed nomogram may result in more-accurate diagnostic predictions for benign or malignant lymph nodes in patients with HIV infection.
