Abstract

 Conventional plastics which are often used in everyday life cause the accumulation of plastic waste and cause environmental pollution problems because plastics are difficult to decompose by microorganisms. Bioplastic is one of the solutions used in reducing environmental pollution, its nature is easily degraded and decomposed by microorganisms in a fairly short time making the plastic environmentally friendly. The materials used in the manufacture of bioplastics in this study are corn starch and cellulose fibers which are extracted from wasted paper using the acetylation method. The general objective of this study was to determine the effect of adding cellulose fibers to bioplastic samples with glycerol acting as plasticizers. Bioplastic analysis is carried out by measuring the tensile strength test, water absorption test, biodegradation test, and observing the structure using an optical microscope. The best tensile strength test results were obtained in the addition of 2 grams of cellulose pulp, with a tensile strength value of 1.65 MPa and a percentage of the sample's elongation value of 25%. For the water absorption test with the smallest percentage was obtained the addition of 1 gram of pulp with a value of 35.48%. The best biodegradation test results were in the addition of 1 gram and 2 grams, with a degradation time of 13 days.

Bladder cancer is one of the ten most prevalent forms of cancer around the globe, with an expected 573,000 new cases and 213,000 fatalities in 2020. Transurethral resection of bladder tumours (TURBT) is the mainstay of diagnosis and treatment for non-muscle-invasive bladder cancer (NMIBC) and provides both the stage and the foundation for risk stratication. At the time of diagnosis, seventy percent of bladder cancers are nonmuscle-invasive and are treated via transurethral resection (TUR). Essential to the successful management of these tumours are adequate initial resection and an accurate histological diagnosis of the resected tissue. Transurethral resection of bladder tumours (TURBT) continues to be the treatment of choice for non-muscle-invasive bladder cancer (NMIBC) to date. Thirty participants who underwent TURBT were enrolled in the present study to determine recurrence and complications. The average age of the study participants was 57.40+10.35 years. 76.67% of the 30 study participants were male, and 70% have a smoking history. 83.33 percent of study participants were found to have T1 cancer staging, and 86.77 percent had low-grade cancer. It was determined that the average tumour size of the study participants was 2.7+0.6 cm. It was discovered that 30% of the study participants had tumours in the lateral wall, followed by 20% in the posterior wall. 13.33% of the participants in the study were found to have tumour recurrence, and 10% were found to have complications. Hence we conclude that transurethral resection of bladder tumours is the therapy of choice for non-muscle-invasive bladder cancer. When administered correctly, a high-quality, comprehensive TURBT can inuence diagnostic accuracy, recurrence, and disease progression.

Published: July 2023

Crocus sativus, also known as "yellow gold," is a plant that is cultivated in countries such as Iran, India, and Greece. It is made up of dried red stigma and contains over 150 volatile compounds that are responsible for its aroma, including terpenes, terpene alcohol, and their esters. Two of its components, picrocrocin and safranal, contribute to its bitter taste and hay-like fragrance. This plant has several medicinal properties, including antioxidant, anti-tumorogenic, anti-inflammatory, and antidepressant effects, which make it effective in managing Oral Lichen Planus (OLP). A search of scientific journals was conducted to identify relevant articles on the potential use of crocus sativus in treating OLP. The literature suggests that crocus sativus can be used to successfully treat OLP, but more clinical studies are needed to establish its efficacy. The pharmacological properties of saffron, especially its crocin and safranal components, make it a potential therapeutic agent for various diseases, including cancer and oxidative stress. However, further laboratory-based research and clinical trials are needed to determine the precise mechanisms of action and establish its role as a novel therapeutic agent in OLP

The aim: To study the family influence on the formation of children’s motivation for a healthy lifestyle.
Materials and methods: The medical and sociological study among parents was conducted to assess their children’s adherence to the principles of a healthy lifestyle and the influence of the family on the formation of children’s motivation for a healthy lifestyle. The survey was conducted using a specially designed questionnaire using Google Forms. The design of the questionnaire was typical and contained the following structural components: addressing the respondent, obtaining informed consent to participate in the survey, and blocks with targeted questions (25 questions in total). The research involved 150 parents (including 54.7 % (82 people) of women and 45.3 % (68 people) of men).
Methods: bibliosemantic, system-oriented analysis and logical generalization, medical and sociological (questionnaire), statistical data processing.
Results: It has been found that positive attitudes towards a healthy lifestyle prevail in the families of the respondents (44.0 %), 42.0 % of parents indicated that their family members regularly adhere to a healthy lifestyle. Herewith, 48.0 % are interested in teaching their children about a healthy lifestyle. The main motives that most parents form in their children regarding a healthy lifestyle are maintaining and promoting health (38.0 %), improving physical condition (16.0 %), and creating a healthy family (10.0 %). However, almost a third of parents do not instill responsibility for their children’s life and health due to a lack of time and knowledge about a healthy lifestyle.
Conclusions: To foster a positive attitude toward a healthy lifestyle in children, parents should set their example, create favorable conditions for a healthy lifestyle, and follow traditions related to active recreation, sensible nutrition, and the absence of bad habits. Children’s motivation for a healthy lifestyle is the main responsibility of the family.

Published: July 2023

Gagarinite-(Ce) [Na(Ca,Ce)2F6] has been synthesized as a product in experiments designed to examine the fluid-induced alteration of chevkinite-(Ce). The experiments were conducted at 600 °C and 400 MPa for 21 days and at 550 °C and 200 MPa for 63 days. At 600 °C, a rim of gagarinite-(Ce) was seen to develop around chevkinite-(Ce), which was itself enclosed in a glassy, amorphous material containing inclusions of albite. At 550 °C, the chevkinite-(Ce) was observed to be surrounded by a rim of gagarinite-(Ce) and fluorbritholite-(Ce), which in turn was enclosed in massive narsarsukite with inclusions of albite. This assemblage was associated with a sodic pyroxene. In the 550 °C run both rims with gagarinite-(Ce) were subsequently overgrown by both Ce-bearing frankdicksonite and a lamprophyllite group mineral identified as delindeite. Electron probe microanalyses are given of all reactant phases. The stability conditions of gagarinite-(Ce) are in accord with those inferred from the only natural occurrence, Strange Lake, Canada. The formation of gagarinite-(Ce) is ascribed to NaF being the only component added in the experiments, resulting in a very high Na/Ca ratio in the system. New parageneses for narsarsukite, frankdicksonite, and delindeite are reported.

Published: July 2023

In this study, a hybrid DC-DC boost converter was proposed for high voltage gain. The proposed converter was analyzed and designed. The active soft switching method was applied to proposed converter to reduce the losses due to hard switching. While the main switch of proposed converter is turning off, the main switch current is zero during voltage transition and in the opposite case, the main switch voltage is zero during current transition. Thus, power losses for both states of the main switch were minimized. The simulation for MOSFET and IGBT based hybrid DC-DC boost converter with active soft switching were obtained for different loads.

Published: July 2023

Señora editora:
Sabemos que el desarrollo de la vacunación ARN intramuscular ha sido una medida de prevención efectiva contra la infección por SARS-CoV-2 al producir respuestas inmunes humorales y celulares, que previenen la viremia y las manifestaciones sistémicas provocadas por la COVID-19. Sin embargo, Tiboni et al. detallan que la vía intramuscular no brinda una protección completa en la replicación viral debido a la ausencia de activación de la inmunidad de las mucosas de las vías aéreas superiores, conservando el riesgo de transmisión.
La vacunación intranasal es una vía de inmunización novedosa, que utiliza como entrada la mucosa respiratoria para el desarrollo de anticuerpos. La inmunización intranasal es una opción prometedora para combatir la COVID-19, ya que al utilizar la misma ruta de infección que el virus, esteriliza las vías respiratorias y previene la transmisión del virus; además, su administración es fácil y es conveniente para las personas con tripanofobia.

A gyermekek egészséges fejlődéséhez nélkülözhetetlen a megfelelő pihenés, alvás, s noha az alvás szükség és szokás egyaránt, az elalvás, illetve az ezt támogató altatás már nem mindig olyan egyértelmű és könnyed feladat. A szakirodalom több altatási stratégiát is felkínál, viszont az évszázadok során az eltérő kultúrákban fontos szerepet játszott altató mondókák, bölcsődalok említése csak periférikusan érhető tetten. Ez a gyermekkor költészetének a lírai játékdalok csoportjába tartozó sajátos műfaja azonban nemcsak a gyermekek nevelésével összefüggő módszertani kérdések tekintetében, hanem néprajzi, irodalmi vonatozásban is „méltatlanul elhanyagolt műfaj”, ahogy erre Katona Imre többször is felhívta a figyelmet. Az írás e tényekből kiindulva állítja fókuszba ezt a népköltészeti műfajt, s eredeti funkcióját kiemelve kívánja ráirányítani a figyelmet a gyermeknevelésben.

This descriptive qualitative research uses conversation in 10 language use activities as the data source. The data are utterances containing code mixing. Data collection techniques involve field observation, by recording participant conversations in 10 activities. Participants are millennials in Banggai who are native speakers of Banggai language who use Banggai language in in their daily life. The researchers sort the utterances to separate data and non-data in recorded conversations. Data analysis code mixing identification and classification. The researchers interpret the results of the analysis based on the theory and present them in the form of description. The results of this study indicate that Banggai millennials employ all forms of code mixing in all conversational activities studied. The forms include insertion, alternation and congruent lexicalization. In other words, participants insert Indonesian words, phrases, clauses and dialects into their Banggai language utterances during conversation. The tendency to insert Indonesian in the utterances of Banggai millennials is an alarming signal for the continuity and the existence of the Banggai Language. Losing the local language will eliminate the Banggai culture at the same time. The results of observations in 10 conversational activity settings showing the mixing of Banggai language code with Indonesian reflect the signal. There are needs of serious efforts from the Banggai Laut Government and a traditional apparatus based in Banggai Laut, to make Banggai language into the language of instruction, which continue to live and sustainable in society, as it is related to the central position of Banggai Laut , as the center of the Banggai Kingdom.

Published: July 2023

Objective: This study compared the linear acceleration generated from an impact to a manikin's head wearing an off-the -shelf “standard” bicycle helmet (stdBH) compared to a modified bicycle helmet (modBH) (original foam replaced with softer polyolefin foam). Methods: Pairs of 5 different bicycle helmets from a wide price range ($20-$90) were tested (standard versus modified). The head impact was simulated by striking the test bicycle helmet placed onto the head of a Century BOB boxing manikin, with a conventional football helmet (4.6 kg additional weight added) swung from a 1.2 meter rope and released from an angle of 45º serially for multiple data points as in Figure 2. The manikin's bicycle helmet was struck by the football helmet in the frontal, left parietal, and occipital locations for 12 trials each. Each of three accelerometers located at the manikin’s forehead, apex of the head, and right ear collected data on linear acceleration in the X, Y, and Z planes. Results: Mean linear acceleration in G's (9.8 m/sec/sec) was obtained from the three accelerometer locations on the manikin's head for each striking position. The mean linear accelerations across the 5 different helmet pairs are summarized in the graphs (Figure 3). For each of the three striking locations, there were statistically lower striking forces sustained with the modified softer foam bicycle helmet (modBH) compared to the standard bicycle helmet (stdBH). The greatest reductions were observed in the apical accelerometers when the manikin was struck from the occipital and parietal locations. Conclusion: These results suggest that softer foams in bicycle helmets may reduce injury from bicycle accidents. Further research on this topic can lead to the development of safer and more effective bicycle helmets.

Actualmente, muchas parejas pasan por diversos problemas, incluso a los pocos meses de haber contraído matrimonio, dada la gravedad de estos, se llega a la decisión de romper el vínculo matrimonial, pero no lo pueden hacer en tanto no se cumplan con los plazos que establece la normatividad vigente. En ese sentido, la presente investigación tiene como objetivo, determinar en qué medida la separación convencional se relaciona con el divorcio ulterior, en el sistema civil peruano, 2021. Para ello, en el marco de una investigación con enfoque cualitativo, de nivel descriptivo, explicativo, correlacional y, de diseño no experimental y de corte transversal, se hizo el levantamiento de información respectivo utilizando como instrumento el cuestionario, el mismo que se aplicó a una muestra de 30 especialistas en separación convencional y divorcio ulterior. Los resultados demuestran que principalmente más de la 3era parte de los encuestados consideran que el plazo de 2 años para que las parejas accedan a la separación convencional nunca ha sido el más adecuado, más aún si la ¼ parte de estos, perciben que pocas veces las características de este proceso han sido las correctas. En este marco más de la mitad de encuestados afirman que el trámite en la notaria es siempre mucho más rápido que en otra alternativa existente. Por ello se llegó a concluir que existe relación proporcional entre las variables de estudio.

La investigación titulada: Eficacia del derecho constitucional de acceso a la información pública en la Municipalidad Distrital de Salas Guadalupe en tiempos de pandemia - 2022, partió de la problemática socio-jurídica observada en dicha comuna, en donde muchos pobladores manifestaron disconformidad por sus autoridades, no solo por la forma como vienen desarrollando su gestión sino también por la falta de transparencia en los tiempos actuales de crisis generada por la pandemia COVID-19, pues ciertos funcionarios y/o empleados públicos municipales designados para brindar información pública y relacionada directamente con el Derecho de acceso a la información pública atropellan dicho derecho al no brindar información pública cuando se le solicita, al mostrar renuencia de proporcionar información sin una justificación razonable, asi como también estos funcionarios muchas veces no publican información en el portal de transparencia, también no se hace de conocimiento público los mecanismos de publicación y metodología de las finanzas públicas, entre otras limitaciones a este derecho, por ello, se buscó como objetivo central determinar el nivel de eficacia del derecho constitucional de acceso a la información pública en dicha municipalidad. La investigación se orientó bajo una metodología de diseño jurídico descriptivo, se contó con una muestra conformada por 384 pobladores, a los cuales se les aplicaron mediante la encuesta un cuestionario válido y confiable. Entre los resultados, se halló que en un 56,4% existe un nivel regular de eficacia del derecho constitucional de acceso a la información pública, en un 30,6% la ley no resulta eficaz, y en un 13,0% la ley si es eficaz. Por lo que se concluyó que existe un nivel regular o una relativa eficacia del derecho constitucional de acceso a la información pública, pues como se evidencia de la propia realidad socio-jurídica de dicha comuna existen limitaciones y dificultades en los moradores para acceder y gozar de este derecho conforme a ley.

The search for ferromagnetic materials with high Curie temperature (Tc) is a hot issue in condensed matter physics. In this work, an effective machine learning model of Curie temperature based on material component information is established to predict a variety of ferromagnetic materials with high Curie temperature. Based on the collected data of 1568 ferromagnetic materials, and taking the component information of ferromagnetic materials as descriptors, in this work four efficient machine learning models are constructed, namely support vector regression, kernel ridge regression, random forest and extremely randomized trees, through hyperparameter optimization and ten-break cross-validation. Of them, extremely randomized tree model has the best prediction performance, and its cross-validation R2 score can reach 81.48%. At the same time, the extremely randomized tree model is also used to predict 36949 materials in the materials project database, and 338 ferromagnetic materials with Tc greater than 600 K are found in this work. The method proposed in this paper can help obtain ferromagnetic materials with high Curie temperature and accelerate the process of ferromagnetic material design.

Importance

The detection of seasonal patterns in suicidality should be of interest to clinicians and US public health officials, as intervention efforts can benefit by targeting periods of heightened risk.

Objectives

To examine recent trends in suicidality rates, quantify the seasonality in suicidality, and demonstrate the disrupted seasonality patterns during the spring 2020 COVID-19–related school closures among US children and adolescents.

Design, Setting, and Participants

This population-based, descriptive cross-sectional study used administrative claims data from Optum’s deidentifed Clinformatics Data Mart Database. Participants included children aged 10 to 12 years and adolescents aged 13 to 18 years who were commercially insured from January 1, 2016, to December 31, 2021. Statistical analysis was conducted between April and November 2022.

Exposures

Month of the year and COVID-19 pandemic.

Main Outcomes and Measures

Rates and seasonal patterns of emergency department (ED) visits and hospitalizations for suicidality.

Results

The analysis included 73 123 ED visits and hospitalizations for suicidality reported between 2016 and 2021. Among these events, 66.1% were reported for females, and the mean (SD) age at the time of the event was 15.4 (2.0) years. The mean annual incidence of ED visits and hospitalizations for suicidality was 964 per 100 000 children and adolescents (95% CI, 956-972 per 100 000), which increased from 760 per 100 000 (95% CI, 745-775 per 100 000) in 2016 to 1006 per 100 000 (95% CI, 988-10 024 per 100 000) in 2019, with a temporary decrease to 942 per 100 000 (95% CI, 924-960 per 100 000) in 2020 and a subsequent increase to 1160 per 100 000 (95% CI, 1140-1181 per 100 000) in 2021. Compared with January, seasonal patterns showed peaks in April (incidence rate ratio [IRR], 1.15 [95% CI, 1.11-1.19]) and October (IRR, 1.24 [95% CI, 1.19-1.29]) and a nadir in July (IRR, 0.63 [95% CI, 0.61-0.66]) during pre–COVID-19 years and 2021. However, during the spring of 2020, which coincided with school closures, seasonal patterns were disrupted and April and May exhibited the lowest rates.

Conclusions and Relevance

The findings of this study indicated the presence of seasonal patterns and an observed unexpected decrease in suicidality among children and adolescents after COVID-19–related school closures in March 2020, which suggest a potential association between suicidality and the school calendar.
Near‐Infrared‐II Fluorophore with Inverted Dependence of Fluorescence Quantum Yield on Polarity as Potent Phototheranostics for Fluorescence‐Image‐Guided Phototherapy of Tumors

Organic phototheranostics simultaneously having fluorescence in the second near‐infrared (NIR‐II, 1000–1700 nm) window, and photothermal and photodynamic functions possess great prospects in tumor diagnosis and therapy. However, such phototheranostics generally suffer from low brightness and poor photodynamic performance due to severe solvatochromism. Herein, an organic NIR‐II fluorophore AS1, which possesses an inverted dependence of fluorescence quantum yield on polarity, is reported to serve as potent phototheranostics for tumor diagnosis and therapy. After encapsulation of AS1 into nanostructures, the obtained phototheranostics (AS1R) exhibit high extinction coefficients (e.g., 68200 L mol−1 cm−1 at 808 nm), NIR‐II emission with high fluorescence quantum yield up to 4.7% beyond 1000 nm, photothermal conversion efficiency of ≈65%, and 1O2 quantum yield up to 4.1%. The characterization of photophysical properties demonstrates that AS1R is superior to other types of organic phototheranostics in brightness, photothermal effect, and photodynamic performance at the same mass concentration. The excellent phototheranostic performance of AS1R enables clear visualization and complete elimination of tumors using a single and low injection dose. This study demonstrates the merits and prospects of NIR‐II fluorophore with inverted polarity dependence of fluorescence quantum yield as high‐performance phototheranostic agents for fluorescence imaging and phototherapy of tumors.
