BackgroundNon-suicidal self-injury (NSSI) is an important health problem among adolescents and young adults. The aims of this study were to determine NNSI status and its associated factors among students.MethodThis cross-sectional study has been conducted in 4715 high school and university students from the West and Northwest provinces of Iran. Multi-stage sampling was used to select students and all students completed survey questionnaires. Data analysis was performed using chi-square, Fisher’s exact test, binary and logistic regression.ResultThe lifetime prevalence of NSSI was estimated as 24.4% among all participants (21.4% in high school students vs. 29.3% in university students). After adjustment for other factors, age (OR=1.08,95%CI:1.03-1.12), cigarette smoking as an experimenter (OR=1.94,95%CI:1.61-2.34) and regular (OR=3.80,95%CI:2.96-4.89) compared to nonsmokers, membership in a sport team (OR = 1.26,95%CI:1.08-1.48), having physical fight (OR = 2.18,95%CI:1.85-2.57), doing general risk taking behavior (OR = 2.05,95%CI:1.66-2.53), and self-esteem (OR=0.93,95%CI:0.92-0.95) were associated with experience of NSSI.ConclusionOur results suggested that the prevalence of NSSI was relatively high among high school and university students. To diagnose, prevent, and treat NSSI in teenagers and young adults in Iran, more research is needed to identify the root causes.

BackgroundAs global populations age, the suitability of community outdoor spaces for older adult residents has become a critical urban planning concern. However, comprehensive evaluation methods for assessing these spaces are lacking. Objective: This study aims to evaluate the aging-suitability of community outdoor spaces in Zhengzhou, China, and provide optimization suggestions for urban planners and policymakers.MethodsAn evaluation index system was established using the analytic hierarchy process (AHP), with aging-suitability as the goal layer. The criteria layer included outdoor behavioral activities, green space configuration, transportation and road systems, and basic service facilities. The semantic differential (SD) method was employed to conduct a comprehensive evaluation among older adult residents in three communities (A, B, and C) in Zhengzhou city.ResultsThe evaluation revealed that older adult residents generally had a favorable assessment of their community spaces’ aging-suitability. Community A received the highest overall rating. Green space configuration and transportation systems emerged as critical factors influencing aging-suitability.ConclusionThe combined AHP-SD approach proved effective in evaluating the aging-suitability of community outdoor spaces. The study identified key areas for improvement in each community, with variations in strengths and weaknesses across the three sites. Implications: Based on the findings, optimization suggestions are proposed in four aspects: enhancing outdoor behavioral activities, improving green space landscapes, refining road transportation systems, and upgrading basic service facilities. These recommendations can guide urban planners and policymakers in creating more age-friendly community environments.

PurposeThis study investigates the influence of economic conditions, healthcare system capacity, and health-related variables on the proportion of the older adult population (Population ages 65 and above) in European Union countries. It aims to identify how factors such as GDP, unemployment, inflation, healthcare expenditure, hospital bed availability, and the prevalence of chronic diseases impact the aging demographic.MethodsThis study explores the dynamic interactions and temporal relationships between economic stability, healthcare capacity, chronic disease prevalence, and demographic aging patterns. The research employs a mixed-method approach, utilizing System GMM and wavelet coherence analysis on panel data from 27 EU countries between 2000 and 2021.ResultsThe findings reveal significant positive associations between economic prosperity and healthcare resources with the size of the older adult population. Increased GDP, efficient healthcare spending, and hospital bed availability are positively correlated with a larger older adult demographic. In contrast, high unemployment and inflation are linked to negative outcomes for the older adult population, reducing available resources and access to healthcare. Wavelet coherence analysis further uncovers how fluctuations in the prevalence of chronic diseases influence aging trends across different periods and frequencies.ConclusionThe study highlights the importance of integrated economic and healthcare policies to support the growing older adult population. Ensuring economic stability, enhancing healthcare infrastructure, and effectively managing chronic diseases are essential for improving quality of life and promoting sustainable aging in EU societies.

IntroductionWhile pedaling, cyclists rest their pelvis on the saddle, generating pressures on it. The pressures generated on the saddle are influenced by several factors. This study aimed to evaluate whether the flexibility of hamstring and lower back muscles could be considered a predictor of pressures in the anterior region (PAR) on the saddle.MethodsFor this study, 15 young off-road Italian cyclists (11m, 4f) aged 13–16 (Italian Federation categories: ES1, ES2, AL1, AL2) were recruited. Each participant was administered the V sit-and-reach (VSR) to measure the hamstring and lower back muscles flexibility. Subsequently, after performing a bike fitting, the saddle pressures during pedaling at three different intensities (100, 140, 180 W), with participants on their own bike installed on specific bike roller, were recorded. The parameters considered for statistical analysis were front pressure (%) and back pressure (%).ResultsThe hamstring and lower back muscles flexibility, as result of the VSR test, was a predictor of saddle PAR at 100 W (R2 = 0.362, p = 0.018), at 140 W (R2 = 0.291, p = 0.038), and at 180 W (R2 = 0.349, p = 0.020) of pedaling intensity.ConclusionHigher values of the VSR could predict lower values of the pressures exerted in the front region of the saddle. The hamstring and lower back muscles flexibility may be considered a predictor of PAR on the saddle.

IntroductionAntibiotic use in broilers is being discouraged globally due to the challenges it poses. This study was conducted to assess the effects of supplementing broilers with a Symbiotic-Enzyme complex (SEC) containing prebiotics (mannose oligosaccharides), probiotics (Clostridium butyricum and Bacillus subtilis), and enzymes (glucose oxidase, and α-galactosidase) as an alternative to antibiotics on growth performance, carcass and meat quality traits, mortality, linear body measurements, intestinal morphology and immune organ indexes.MethodA total of 864 mixed-sex 1-day-old arbor acres (AA+) broilers were allocated to 8 experimental groups replicated 9 times with 12 chickens per replicate. These included 6 treatment groups with SEC inclusion levels of 0.025, 0.04, 0.05, 0.06, 0.08, and 0.10%, respectively, and two control groups: a negative control group containing a basal diet only and the positive control group (Antibiotics group) containing a basal diet and antibiotic oxytetracycline added at 0.2%. Growth performance was measured on day 21 and 42, and the mortality, carcass, meat quality traits, linear body measurements, intestinal morphology, and organ size indexes were measured on day 42.ResultsThe results indicated that supplementing broilers with 0.1% SEC resulted in insignificant (P &gt; 0.05) increases in average daily feed intake (ADFI), significant (P &lt; 0.05) increases in the average daily gains (ADG), and significant (P &lt; 0.05) reduction in a feed-to-gain ratio (F/G) in all the phases compared to the control and antibiotics groups. Supplementation of broilers with 0.1% SEC inclusion levels also significantly (P &lt; 0.05) increased the body slope length, chest width, chest depth, keel length, and shank circumference. Furthermore, broilers on diets containing 0.1% SEC inclusion level also had significantly (P &lt; 0.05) higher dressed, semi-evisceration, evisceration, and breast muscle percentages. Including SEC at 0.1% also significantly (P &lt; 0.05) increased villus height and villus-to-crypt ratio (V/C) but reduced crypt depth in the duodenum, jejunum, and ileum compared to the control groups. SEC inclusion at 0.1% significantly (P &lt; 0.05) increased the spleen, bursal, and thymus indexes, respectively.ConclusionSupplementation of broilers with 0.1% SEC can be used as an antibiotic alternative because it increases the F/G, improves the carcass and meat quality, increases the body conformation, improves the small intestines' functions, and immune organ size.

Значительный прогресс в лечении множественной миеломы (ММ) был достигнут благодаря появлению многих новых препаратов. Однако, несмотря на это, ММ остается неизлечимым заболеванием с неизбежным рецидивом у большинства пациентов. Мы описали случай лечения венетоклаксом рецидива ММ высокого риска (делеция локуса гена ТР53) с транслокацией t(11;14)(q13;q32) у пациента молодого возраста с выраженной коморбидностью. Клинические проявления дебютировали гиперкоагуляционным синдромом, включая рецидивирующий инфаркт миокарда со снижением фракции изгнания левого желудочка до 47%, тромбозы глубоких вен и инфаркт головного мозга в последующем. После 5 циклов химиотерапии с бортезомибом, циклофосфамидом и дексаметазоном достигнута полная ремиссия, но через 8 мес. развился ранний рецидив. Учитывая транслокацию t(11;14)(q13;q32), назначена иммунохимиотерапия с венетоклаксом (венетоклакс, даратумумаб, карфилзомиб и дексаметазон), которая привела к стойкой второй полной ремиссии, продолжи- тельностью более 14 мес. В кратком обзоре литературы анализируются клинические особенности ММ с t(11;14)(q13;q32) и эффективность таргетной терапии венетоклаксом, проблемы венозной тромбоэмболии и сердечно-сосудистых осложнений у пациентов с парапротеинемиями.
Significant progress in the treatment of multiple myeloma (MM) has been achieved thanks to the introduction of many new drugs. However, despite this, MM remains an incurable disease with inevitable recurrence in most patients. We described a case of venetoclax treatment of high-risk MM recurrence (deletion of the TP53 gene locus) with translocation t(11;14)(q13;q32) in a young patient with severe comorbidity. Clinical manifestations debuted with hypercoagulation syndrome, including recurrent myocardial infarction with a decrease in the left ventricular ejection fraction to 47%, deep vein thrombosis and subsequent cerebral infarction. After 5 cycles of chemotherapy with bortezomib, cyclophosphamide and dexamethasone, complete remission was achieved, but an early relapse developed after 8 months. Taking into account the translocation t(11;14)(q13;q32), immunochemotherapy with venetoclax (venetoclax, daratumumab, carfilzomib and dexamethasone) was prescribed, which led to a stable second complete remission lasting more than 14 months. A brief review of the literature analyzes the clinical features of MM with t(11;14)(q13;q32) and the effectiveness of targeted venetoclax therapy, problems of venous thromboembolism and cardiovascular complications in patients with paraproteinemia.

Температура является важным фактором, влияющим на эффективность биологического удаления азота активным илом на очистных сооружениях. В экспериментах использовался лабораторный SBR-реактор, активный ил для культивирования был получен из аэротенков городских очистных сооружений. Для определения таксономического состава бактерий активного ила использовался метод высокопроизводительного секвенирования участка ДНК, кодирующего 16S рРНК. Скорость нитрификации определялась при температуре воды 1, 5, 8, 11, 17, 19 и 21 °С. Установлено, что в активном иле присутствовали нитрифицирующие бактерии Nitrosomonas spp. и Nitrospira spp., относительная численность которых составляла 0,07% и 0,34% соответственно. Максимальная скорость нитрификации наблюдалась при 21 °C и составляла 4,3 мг N–NO3 на 1 г беззольного вещества активного ила в час. Скорость нитрификации уменьшалась с понижением температуры и при 1 °C составила 0,3 мг/(г·ч) по N–NO3. Результаты исследования могут быть использованы в качестве теоретической основы для оптимизации эксплуатации очистных сооружений в районах с низкими температурами для повышения эффективности удаления азота из сточных вод.
Temperature has been an important factor affecting the efficiency of biological nitrogen removal by activated sludge at wastewater treatment facilities. A laboratory SBR reactor was used in the experiments; activated sludge for cultivation was obtained from aeration tanks of the municipal wastewater treatment facilities. The taxonomic composition of bacteria in activated sludge was determined by high throughput sequencing of the DNA section encoding 16S rRNA. The nitrification rate was determined at water temperatures of 1, 5, 8, 11, 17, 19, and 21 °C. Nnitrifying bacteria Nitrosomonas spp. and Nitrospira spp. were found in activated sludge with the abundance of 0.07% and 0.34%, respectively. The maximum nitrification rate observed at 21 °C was 4.3 mg N–NO3 per 1 g of ash-free substance of activated sludge per hour. The nitrification rate decreased with decreasing temperature and was 0.3 mg/(g·h) by N–NO3 at 1 °C. The results of the study can be used as a theoretical basis for optimizing the operation of the treatment facilities in areas with low temperatures to improve the efficiency of nitrogen removal from wastewater.
Классификация трубопроводов самотечных систем водоотведения при восстановлении с использованием гибких полимерных рукавов
Authors: Захаров Ю.С. 
Published: October 2024

Одним из динамично развивающихся направлений строительной отрасли с начала девяностых годов прошлого века является восстановление поврежденных подземных трубопроводов с использованием технологий «труба в трубе». Восстановленный трубопровод должен соответствовать требованиям, предъявляемым к новым трубопроводам, т. е. быть герметичным, экологически безопасным и безопасным в эксплуатации, устойчивым к статическим нагрузкам, к транспортируемым сточным водам, к истиранию и нагрузкам при струйной водной очистке. На основании статического расчета, выполняемого при выборе параметров новой трубы для восстановления трубопровода, следует подтвердить несущую способность, пригодность к эксплуатации и статическую устойчивость трубопровода после выполнения восстановительных работ, а также, при необходимости, невозможность обрушения (провала) грунта. Четкое определение необходимой толщины стенки новой полимерной трубы, выбор подходящей технологии для восстановления трубопровода и срок его службы после восстановления во многом зависят от правильной классификации восстанавливаемого трубопровода. Поэтому для качественного выполнения статического расчета, минимизации ошибок при выборе конструкции и параметров гибкого полимерного рукава, а также для обеспечения длительной безаварийной эксплуатации системы «новая труба – трубопровод – грунт» следует тщательно проводить визуальное обследование восстанавливаемого трубопровода в соответствии с приведенной в статье классификацией.
One of the dynamically developing areas of the construction industry since the early nineties of the last century has been the rehabilitation of damaged underground pipelines using «pipe-in-pipe» technologies. The rehabilitated pipeline shall meet the requirements for new pipelines, i. e. be hermetic, environmentally safe and safe in service, resistant to static loads, to transported wastewater, to abrasion and loads during water blasting. Based on the static calculation performed when selecting the parameters of a new pipe for pipeline rehabilitation, it is necessary to confirm the bearing capacity, serviceability and steadystate stability of the pipeline after rehabilitation, as well as, if necessary, the impossibility of soil collapse (sinking). A clear definition of the required wall thickness of a new polymer pipe, the choice of a suitable technology for pipeline rehabilitation and the service life of the pipeline after rehabilitation largely depend on the correct classification of the pipeline being restored. Therefore, in order to perform a high-quality static calculation, minimize errors in selecting the design and parameters of a flexible polymer liner, as also to ensure long-term trouble-free operation of the «new pipe – pipeline – soil» system, a visual inspection of the pipeline being restored should be carefully carried out in accordance with the classification given in the article.
Data-driven prediction of higher-order structure in carbon nanotube films for high thermoelectric power factor
Authors: Kobayashi Junei , Yamamoto Takahiro 
Published: October 2024

Abstract
We optimized the higher-order structures and semiconducting purity of single-walled carbon nanotubes (SWCNTs) to enhance the thermoelectric power factor PF by combining the thermoelectric random stick network (TE-RSN) method and a genetic algorithm. The PF of the optimized films was increased approximately fivefold for initial random structures. In addition, while the random structures showed the maximum PF when the ratio of semiconducting to metallic SWCNTs R
s exceeded 0.98, the optimized structures converged to an R
s of approximately 0.9. The optimized structures exhibited an increased local density and the peak of alignment angle distribution, leading to an increase in both the electrical conductivity and the Seebeck coefficient. We interpreted the increase in the Seebeck coefficient using a serial model. The results indicated that the reduction in the number of contacts within the paths and the subsequent increase in temperature difference on semiconducting SWCNTs led to the increase in the Seebeck coefficient.
Impact of grain size on the performance of WSe2 FETs revealed by first-principles calculations
Authors: Chen Junjie , Shiraishi Kenji 
Published: October 2024

Abstract
We theoretically investigate the grain size dependence of the mobility of WSe2 FETs, and the experimental results which have been recently reported. A larger grain size (LG) WSe2 has been modeled by a single monolayer WSe2 of infinite length. We model a smaller grain size (SG) WSe2 as a partial monolayer of WSe2 with a zigzag edge WSe2 nanoribbon. Our results show that the step edges of the partial monolayer WSe2 function as electron traps. Moreover, the effective mass of SG WSe2 appears to be much larger than that of LG WSe2 because of hybridization with gap states originating from step edges at the conduction band minimum. These results coincide with recent experiments that show that the on-currents of the SG WSe2 are much lower than those of the LG WSe2. Hence, our calculated results indicate that LG fabrication is essential for advanced large-scale integration (LSI) using WSe2 FETs.
