Teachers’ perceptions and lived experiences of challenges in culturally diverse classrooms: establishing an equitable school environment
Authors: Aydin Hasan 
Published: November 2023

Abstract
The increasing population of students of color in public school settings in the United States is a persistent challenge for White teachers teaching diverse student populations with students from racially, ethnically, culturally, and linguistically diverse families and communities of lower socioeconomic status to make learning more effective in their classrooms. This qualitative study aimed to identify the challenges in teaching students of diverse backgrounds in public school settings in a school district in Houston, the most ethnically diverse large metropolitan area in the United States. The study focused on the lived experiences with in-depth and semi-structured interviews conducted with 7 participants (6 females; 1 male) to gain insights into their perspectives and understand the essence of their experiences. The findings showed that the lack of language proficiency and trained teachers in culturally responsive teaching often create barriers to effective schooling. The findings emphasize the importance of culturally responsive teaching to prepare highly effective teachers to address the needs of an increasingly diverse student population in the United States.

Abstract
Recycled paper has become increasingly used as a raw material in the paper industry. However, hornification limits its application. Herein, the effect of recycling on the mechanical properties and microstructure of khasi pine pulp was systematically studied. The mechanical properties deteriorated and water retention value decreased after recycling. X-ray diffraction and Fourier-transform infrared spectroscopy revealed that cellulose crystallinity increased and partial cocrystallization occurred on cellulose microfibrils. Through the analysis of the morphology of secondary fibers by FQA, the loss of fine fibers caused by each reuse was found. Using the filtration method to prepare the recycled paper reduced the loss of fine fibers and improved the mechanical properties, with the tensile strength of a sample prepared using a sand core filter unit for five cycles (8.37 MPa) being like that of a sample prepared using a paper machine after one cycle. The investigation of the internal structure of the paper showed that the retained fine fibers were bonded between the long fibers, promoting the bonding between the fibers. Fine fibers improve the curling and twisting of fibers to some extent, especially in the first three recycling cycles. The hornification phenomenon of recycled paper was studied from the viewpoint of the fiber components, which is important to promote the development and application prospect of recycled paper.

Abstract
Utilizing waste materials to produce sustainable concrete has substantial environmental implications. Furthermore, understanding the exceptional durability performance of ultra-high-performance concrete can minimize environmental impacts and retrofitting costs associated with structures. This study presents a systematic experimental investigation of eco-friendly ultra-high-performance self-compacting basalt fiber (BF)-reinforced concrete by incorporating waste nanomaterials, namely nano-wheat straw ash (NWSA), nano-sesame stalk ash (NSSA), and nano-cotton stalk ash (NCSA), as partial substitutes for Portland cement. The research evaluates the effects of varying dosages of nanomaterials (ranging from 5 to 15% as cement replacements) in the presence of BFs. Rheological properties were analyzed, including flow diameter, L-box, and V-funnel tests. Additionally, the study investigated compressive, splitting tensile, and flexural strengths, load-displacement behavior, ultrasonic pulse velocity, and durability performance of the ultra-high-performance self-compacting basalt fiber (BF)-reinforced concrete (UHPSCFRC) samples subjected to sulfate attack, freeze-thaw cycles, autogenous shrinkage, and exposure to temperatures of 150, 300, 450, and 600°C. Microstructural characteristics of the mixtures were examined using X-ray diffraction (XRD) analysis. The findings reveal that self-compacting properties can be achieved in the UHPSCFRC by incorporating NWSA, NSSA, and NCSA. The presence of 10% NWSA significantly improved the mechanical properties of the UHPSCFRC, exhibiting more than 27.55% increase in compressive strength, 17.36% increase in splitting tensile strength, and 21.5% increase in flexural strength compared to the control sample. The UHPSCFRC sample with 10% NWSA demonstrated superior performance across all extreme durability tests, surpassing both the control and other modified samples. XRD analysis revealed the development of microcracking at temperatures of 450 and 600°C due to the evaporation of absorbed and capillary water and the decomposition of ettringites.

Abstract
Smart solutions in cultural heritage sites play an important role in both preserving traditional values and utilizing methods that combine modern technology and innovation. Smart solutions also have a significant role in promoting sustainability and enhancing the visitor experience. This study primarily focuses on management systems in cultural heritage sites and the use of effective smart solutions and digital technologies within these systems. By examining innovative initiatives in Florence, one of the leading cities in the field of digital technologies, methods used to address issues related to historical site management were identified. In addition to Florence, intelligent initiatives in the historical city of Yazd and their impact on its management were also discussed. Approaches to address challenges in managing historical sites were explored in the context of smart city components. In this context, the fundamental factors of cultural heritage management systems have been classified from the point of view of the components of a smart city, based on the Florence Management Plan. Thanks to the newly identified technologies and digital platforms, different methodologies were explained for each component. This approach allows us to understand the aspects of cultural heritage site management systems and the implementation plans addressing the issues for successful sites within the context of Smart City components.

Abstract
Gadolinium-based photocatalysts have gained interest in the past few years for their exceptional qualities and are currently being explored as potential photocatalysts for the degradation of organic pollutants and environment restoration. This review paper presents an in-depth examination of the photo-catalytic capabilities of Gadolinium-based nanoparticles (Gd-NPs) and their wide range of applications in the treatment of wastewater and other pollutants. The production processes, optimization variables, modifying procedures, diverse applications, and anti-stokes-up transformation features of Gd-NPs (GdFeO3) have been discussed. Furthermore, it also intends to better understand the redox properties, charge transport, bandgap tenability, blemish management and harmful effects of Gd photocatalysts. The disadvantages of Gadolinium-based small particles remained reviewed and addressed with modified approaches. These findings of literature suggest that Gd-NPs, nano-composite material/heterojunctions, or upconversion nanomaterials are being intensively reported in literature as photocatalytic materials. As a whole, this study offers light on current breakthroughs in Gd-based nanomaterials in regard to their uses in pollution elimination, and to control over environmental pollution and toxicity.

Abstract
Herein bimetallic nanoparticles of Co–Mn were prepared using metal-organic framework (CoMn2 (C2O4)3·6H2O) as a starting material. Initially, the bimetallic organic frame work was prepared which was then subjected to pyrolysis to get the desired product. Techniques like scanning electron microscopy (SEM), Energy-Dispersive X-ray spectroscopy (EDX), X-ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) were used to characterize the bimetallic nanoparticles. These analyses revealed that the Co–Mn nanoparticles consisted of finely distributed Mn and Co, along with O in the composites. XRD data confirmed the presence of nano-scale ranges and alloy formation between Co–Mn. The nanoparticles were employed as adsorbent for methyl violet adsorption, with optimized conditions found to be pH 9, temperature 333 K, adsorbents dosage of 0.01 g, and 30 min of contact time. The pseudo-second-order kinetic model best described the adsorption kinetics data whereas Langmuir isotherm exhibited the closest fit, with a maximum adsorption capacity of 625 mg/g at 333 K. Thermodynamic parameters indicated endothermic processes, with ΔH° = 15.155 kJ mol−1, and the process to be spontaneous with negative ΔG° values −0.303, −0.831, and −1.886 (kJ mol−1) at 293 K, 313 K, and 333 K, respectively. The ΔS° value of 52.76 J mol−1K−1 suggested increased disorder at the solid-solution interface during adsorption. The adsorbent could be effectively used in reclamation of dyes loaded water as alternative of activated carbon.

AbstractPrefrontal cortex (PFC) intrahemispheric activity and the interhemispheric connection have a significant impact on neuropsychiatric disorder pathology. This study aimed to generate a functional map of FC intrahemispheric and interhemispheric connections. Functional dissection of mouse PFCs was performed using the voltage-sensitive dye (VSD) imaging method with high speed (1 ms/frame), high resolution (256 × 256 pixels), and a large field of view (∼10 mm). Acute serial 350 μm slices were prepared from the bregma covering the PFC and numbered 1–5 based on their distance from the bregma (i.e., 1.70, 1.34, 0.98, 0.62, and 0.26 mm) with reference to the Mouse Brain Atlas (Paxinos and Franklin, 2008). The neural response to electrical stimulation was measured at nine sites and then averaged, and a functional map of the propagation patterns was created. Intracortical propagation was observed in slices 3–5, encompassing the anterior cingulate cortex (ACC) and corpus callosum (CC). The activity reached area 33 of the ACC. Direct white matter stimulation activated area 33 in both hemispheres. Similar findings were obtained via DiI staining of the CC. Imaging analysis revealed directional biases in neural signals traveling within the ACC, whereby the signal transmission speed and probability varied based on the signal direction. Specifically, the spread of neural signals from cg2 to cg1 was stronger than that from cingulate cortex area 1(cg1) to cingulate cortex area 2(cg2), which has implications for interhemispheric functional connections. These findings highlight the importance of understanding the PFC functional anatomy in evaluating neuromodulators like serotonin and dopamine, as well as other factors related to neuropsychiatric diseases.

Carcinosarcoma is a rare type of prostate neoplasms and accounts for less than 1 % of all malignant tumors of the prostate. This kind of tumor is characterized by the absence of prostate-specific antigen elevation in most cases, which leads to diagnosis of metastatic disease in a quarter of patients. Moreover, carcinosarcoma of the prostate has an extremely poor clinical prognosis. From the morphological point of a view, biphasicity is a typical feature for these tumors. As a rule, epithelial component is represented by poorly differentiated acinar adenocarcinoma. However, in some literature cases adenogenous component was represented by ductal or neuroendocrine carcinoma. Sarcoma component can be represented by any sarcoma type. Currently, pathogenesis of carcinosarcomas isn’t clear. In this report, we describe a clinical case of carcinosarcoma of the prostate in a 72-year-old male.

Background. Currently, kidney cancer remains one of the most common oncourological diseases with relatively high mortality rate.Aim. To study the main epidemiological indicators of malignant neoplasms of the kidney in various regions of Russia and Saint Petersburg.Materials and methods. Based on the data from the Department of Medical Statistics of Tumor Diseases of the Medical Information and Analytical Center, the epidemiological indicators of malignant neoplasms of the kidney for the period between 2016 and 2021 in Russia, individual Federal Districts of the country and Saint Petersburg were analyzed.Results. Despite the increase in the prevalence of malignant neoplasms of the kidney, medical oncological care for the population is at an appropriate level. Most cases of the disease are diagnosed at early stages, there is a decrease in patient mortality rates and an increase in 5-year survival, which indicates the effectiveness of ongoing anticancer measures. In a number of Federal Districts, a number of indicators showed a negative trend compared to the all-Russia data, which requires close attention.Conclusion. The analysis of statistical data of patients with malignant neoplasms of the kidney can be used to optimize the algorithms for diagnosing and treating this category of patients, as well as to improve oncological care for the population.

Aim. To evaluate the effect of cytoreductive nephrectomy (CN) on overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) and to identify a group of patients who are candidates for cytoreductive surgical treatment.Materials and methods. We retrospectively analyzed a database of 403 patients with mRCC treated at the Moscow City Oncological Hospital No. 62 and the City Clinical Oncological Dispensary (Saint Petersburg) between 2006 and 2022. In total, 330 (81.9 %) patients underwent CN. All patients received systemic anti-tumor therapy: targeted anti-angiogenic therapy - 317 (78.6 %), cytokines - 61 (15.1 %), checkpoint inhibitors - 25 (6.2 %). The groups of operated and non-operated patients were unbalanced: CN was more often not performed in patients with multiple metastases, bone and liver lesions, laboratory abnormalities (anemia, increased serum alkaline phosphatase and lactate dehydrogenase) and unfavorable prognosis per IMDC (International mRCC Database Consortium) classification (p >0.05 for all). Results. CN was associated with a significant increase in OS compared with primary tumor preservation in situ: median OS was 36 months with 95 % confidence interval 29.1-37.1, and 11 months with 95 % confidence interval 8.1-21.3, respectively (p <0.0001). The benefit for OS in the CN group was also observed in clear-cell mRCC (p <0.0001), grade G3 (p <0.0001), multiple metastases (p <0.0001) groups, and in the IMDC poor prognosis group (p <0.0001). Conclusion. CN in selected mRCC patients results in a significant increase in OS. Further research is needed to determine selection criteria for surgical treatment candidates.

Published: November 2023

The article presents data on the differential expression of genes of structural and regulatory proteins of connective tissue (COLIA1, fibronectin, elastin, TGF-β1, LOX) in women with pelvic organ prolapse and stigmas of undifferentiated connective tissue dysplasia (UCTD) compared to patients with prolapse but without UCTD stigmas.
Research objectives: analysis of the prognostic significance of differential expression of structural and regulatory genes of connective tissue proteins COLIA1, fibronectin, elastin, TGF-β1, LOX as factors associated with the vaginal prolapse among Ukrainian women.
Materials and methods. Vaginal tissue samples were taken from 18 patients at the menopausal age with vaginal prolapse III, IV degree, which required surgical correction during vaginal hysterectomy and/or plastic surgery of vaginal walls. The main group included 11 patients with clinical and anamnestic UCTD stigmas, the comparison group included 7 women without it. Gene expression analysis of structural and regulatory proteins of the extracellular matrix of connective tissue was performed using real-time quantitative polymerase chain reaction. The relative number of transcripts of the studied genes was normalized by the expression level of the GAPDH gene. The data were calculated using the 2–ΔΔCt method.
Results. There was decrease in gene expression of the main structural proteins of the extracellular matrix of the connective tissue: COLIA1 (t=-1.7; p=0.044), fibronectin (t=1.66; p=0.047), elastin (t=-1.75, p=0,04), gene of the regulatory protein LOX (t=-1.8, p=0.035) and no statistically significant difference in the TGF-β1 gene in patients with pelvic organ prolapse and clinical and anamnestic UCTD stigmas.
Conclusions. Statistically significant lower expression of the genes of the main structural proteins of the extracellular matrix of the connective tissue and the gene of the regulatory protein LOX in patients with pelvic organ prolapse and clinical and anamnestic UCTD stigmas is evidence of the importance of genetically determined pathological remodeling of the connective tissue in the etiology of genital prolapse.

Published: November 2023

Introduction: The burden of HIV-AIDS cases in Indonesia remains high, while HIV-AIDS promotion programs targeting students remain low. Game-based learning has not been investigated as an alternative method for improving HIV-AIDS awareness among students. Aims: this study quantifies the impact of the flashcard-based educational game invented by YARSI HIV-AIDS Care on high school students in Jakarta. Method: A simple randomized controlled study was conducted among 112 SMA 27 Jakarta students (intervention, n=56; control, n= 56). The HIV-AIDS knowledge and attitude scores before and after the educational game were evaluated using a validated questionnaire. An intervention using a flashcard-based game is conducted online. Univariate and Bivariate analyses of the pre-and post-scores for both groups were performed. Result: Following the game, there was a considerable improvement in the HIV-AIDS comprehensive knowledge scores (pre-test vs. post-test, 65 vs. 90, p<0.01), while the control score remained unchanged. The intervention group also had higher knowledge and attitude scores than did the control group (p<0.01). Conclusion: Flashcard-based education games significantly increased comprehensive HIV-AIDS knowledge and positive attitudes toward HIV-AIDS. Thus, this method could be implemented in HIV-AIDS promotion programs that target students
