Os eventos extremos de precipitação são caracterizados por ocorrências de chuvas em que os valores precipitados se distanciam muito de uma condição média, e são de caráter natural ao sistema ambiental, podendo causar desastres. Entretanto, tais eventos podem ocorrer sob influência de fenômenos anômalos muito distantes do local de ocorrência, as teleconexões. A fim de determinar as características das séries temporais, podem ser aplicadas técnicas estatísticas para prever suas ocorrências e estimar as quantidades precipitadas no período. Com isso, este trabalho tem como objetivo analisar as ocorrências de eventos extremos de precipitações máximas, por meio do ajuste à Distribuição de Gumbel, na cidade de Cachoeira do Sul/RS, utilizando dados diários de precipitação no período de 1987 a 2020, provenientes da Agência Nacional de Águas (ANA), bem como estimar os respectivos períodos de retorno para as precipitações máximas. Os resultados obtidos apontaram que a probabilidade de ocorrência da precipitação recorde de 2016, em que foram registrados 185,3 mm em um dia, é de 1,77% e o período de retorno é de 56,6 anos. Utilizando a série temporal de precipitação, a previsibilidade das precipitações máximas segundo os períodos de retorno são: 2 anos (96,7 mm), 5 anos (131,6 mm), 10 anos (154,7 mm), 25 anos (183,9 mm), 50 anos (205,5 mm), 75 anos (218,1 mm), 100 anos (227,0 mm), 200 anos (248,4 mm), 500 anos (276,7) e 1.000 anos (298,0 mm).

Эффективное планирование и управление ЭЭС существенно зависит от точных прогнозов электрических нагрузок на различных этапах ведения режимов ЭЭС. В условиях постоянного роста потребления электроэнергии и изменяющихся климатических условий в электрических сетях нефтегазового комплекса задача разработки точных и надежных методов прогнозирования становится все более критичной. Одним из перспективных направлений и мощным инструментом для решения таких задач в последнее десятилетие стали нейронные сети, выполняющие прогнозирование электрических нагрузок на основе методов обучающихся систем. В данной статье предложено использование модели рекуррентной нейронной сети с долговременной памятью (LSTM – Long-Short Term Memory) для прогнозирования электрических нагрузок. Преимущество этого метода состоит в том, что, в сравнении с существующими методами, LSTM способен учитывать и моделировать долгосрочные зависимости временных рядов за счет наличия в модели ячейки памяти, которая позволяет выявлять неявные корреляции в данных потребления. Практическое значение данного метода заключается в том, что предлагаемая модель апробирована на реальном наборе данных подстанции 220 кВ. Произведено сравнение модели прогнозирования на основе нейронной сети LSTM со статистическим методом прогнозирования ARIMA, результаты показали среднюю абсолютную процентную ошибку (MAPE – Mean Absolute Percentage Error) 5,57% для модели LSTM и 17,087% для модели ARIMA соответственно.

The Origins of a Near-Ecliptic Merged Interaction Region as a Magnetic-Cloud like Structure Embedded in a Co-rotating Interaction Region
Authors: Maunder Megan L. , Foullon Claire , Forsyth Robert , Barnes David , Davies Jackie
Published: January 2024

Abstract. Using remote-sensing and in-situ observations across multiple spacecraft with complimentary methods of analysis, we investigate a Magnetic Cloud Like-structure (MCL) observed in-situ on 3–4 July 2007 near the ecliptic at OMNI, STEREO-A and -B (all within 15° longitude of Earth). The MCL is entrained in a Corotating Interaction Region (CIR) originating in the Northern heliospheric sector, to create a Merged Interaction Region (MIR). This event allows the comparison of MIR observations at different longitudes showing differences in size, formation of sheath, presence of forward and reverse waves and small-scale structuring, demonstrating the progression of the interaction between the CIR and MCL from West to East. In order to explore its origins further, we compare the MIR with the (Interplanetary) Coronal Mass Ejection (ICME/CME) studied in Maunder et al. (2022) in the mid-latitudes at Ulysses containing a Magnetic Cloud (MC) and present a comprehensive discussion of the challenges posed by observing and relating transients not in alignment, across different latitudes and longitudes, and in different solar wind environments. As the CME propagates almost directly towards Ulysses, we find through fitting and modelling that its flanks could also potentially skim the near-ecliptic spacecraft. Length-scale analysis appears to be consistent with this configuration. However, local expansion velocities of the MCL/MC indicate compression near the ecliptic and expansion at Ulysses and the magnetic flux rope orientations and helicities at the different latitudes oppose each other. The CIR likely causes more compression and re-aligns the transient axis orientation near the ecliptic while a High Speed Stream (HSS) from the Southern sector propagates directly into the back of the ICME/MC near the mid-latitude. Opposing signs of helicity could provide indications of flux added in the first stages of CME evolution or magnetic reconnection with the Heliospheric Current Sheet (HCS). These observations and analyses demonstrate the continued challenge of modelling and fitting the propagation of transients embedded in complex solar wind environments. We note some of the caveats and limitations in the methods and highlight the use of multi-spacecraft analysis to disentangle the origin and formation of ICME substructures from the solar wind and other transients.

Method: The study gathered data from 413 young adults in Turkey, averaging 25.73 years in age (Standard Deviation=4.77). Data collection involved using the Positive Childhood Experiences Scale, the Oxford Happiness Questionnaire, and the Social Media Addiction Scale. Mediation analysis was performed to examine the mediating effect of happiness.
Results: Positive childhood experiences were positively associated with happiness and negatively associated with social media addiction. There was a negative relationship between happiness and social media addiction. Happiness played a mediating role in the relationship between positive childhood experiences and social media addiction.
Conclusion: Participants with favorable experiences in childhood reported higher levels of happiness and less social media addiction. These results suggest that the social media addiction prevention and intervention programs should focus efforts on enhancing happiness and positive childhood experiences.

The COVID-19 pandemic brought global disruptions to the way universities operate. Online learning abruptly took priority, as the physical campuses in Australian universities became deserted. Staff had to instantly adapt to major changes in work practices, whilst continuing to support students’ engagement and maintain quality teaching and learning. This article discusses how change fatigue during the pandemic impacted the wellbeing of staff working in the enabling education sector. As staff and student wellbeing is interdependent, gaining a better understanding of the influences on staff wellbeing in the post-pandemic era is worth exploring in the context of discussions around student wellbeing and success. Autoethnographical reflections of eight practitioners at six Australian universities working in teaching, leadership and professional practice in enabling education, were thematically analysed. Emergent data reveals the superordinate theme of change fatigue and sub-themes of time, online fatigue, and emotional labour. This article highlights the impact of workload intensification and change fatigue in educators. Our findings demonstrated that practitioners prioritise their workload and students, to the detriment of their own wellbeing. These findings hold relevance for institutions as they look to address student wellbeing and success, and highlights the value of embedding cultures of care and compassion across all levels of the university.

When considering global interests, it is evident that Russia aims to weaken the dominance of the United States in the current international order and establish itself as a key player in a multipolar world order. In this context, Russia prefers to pursue a policy based on opportunistic actions that would help it be recognized as a global power in different geographic areas and maintain this status. This article aims to examine Russia's growing relationship with Africa from 2014 to the present within the framework of these objectives. In line with Siegle's (2019) claim, the article will argue that Russia's opportunistic approach and Africa's declaration of itself as a "stage" rather than just a destination for Russia indicate that Africa is a global player. The study will discuss Russia's activities in Africa and its influence on the continent in various areas of cooperation, including economics, security, diplomacy, and geopolitics. Additionally, it will touch upon Russia's competition with other global powers in Africa. In this context, the article will demonstrate that Russia's relationship with African countries aligns with its goals of becoming a major power and undermining the global leadership role of the United States in a manner consistent with its global interests. Despite its increasing presence on the continent, the article will conclude by emphasizing that Russia remains a weak player compared to other global powers due to its limited economic and military resources.

The outcomes of public policy in education management process focusing are the concrete changes that occur after the implementation of the decisions taken regarding public policies and the services produced. The results of public policy and the outcomes of educational management process focusing are different from each other. When public policy consequences are mentioned, they mean the consequences that arise from the fact that the public administration chooses to implement or not, and that are intended or not intended for society. Policy demands in educational management process focusing are the demands or requests of other civil or official persons or groups within the political system and in public administration, decision makers who create public policy, when a problem or need arises in society. Individuals, groups and other non-governmental organizations that make up society in democratic countries exert influence on decision-makers in terms of public policy. Education management are decisions made by public officials related to the formulation and implementation of public policy, especially in process focusing, to direct public policy activities and regulate their content. These may be wide-ranging decisions that concern the whole of the country, or they may also be narrower-ranging decisions that concern a certain segment of society. Analysts and policy makers use different models for public policy in education management process focusing. Some researchers state that the use of models often simplifies policy making, suggesting that models are simplified representations of the real world and are used to organize and interpret situations and help predict and explain the consequences of specific options. Some other researchers state that policy models should be considered as indispensable elements in conceptualizing, understanding and clearly establishing the framework of elements related to public policy.

Today, the problem of ash processing is not in the absence of rational technology, but in solving the problem of complex extraction of valuable components (metals) from it. A new method has been developed for calculating and optimizing the technological parameters of key processes of magnetic separation of ash, chlorinating firing of non-magnetic fraction and leaching of the stub with hydrochloric acid (30%) to obtain pure silica. Based on new approaches and solutions using the latest achievements of IT technologies, models have been developed that allow predicting the outputs of the products of the main processes depending on the initial parameters and the consumption of the reagents used. For ease of use in practice, nomograms have been constructed using mathematical models that allow determining the final technological parameters of processes depending on various parameters (productivity, iron content, reagent consumption, etc.) without complex technological calculations. Nomograms are the necessary tools for the selection and justification of the main and auxiliary equipment of the integrated ash processing technology developed by the authors of this work.

The second task is mathematical. A computational and theoretical analysis of the choice of optimal EDM modes for obtaining a high-quality coating with antifriction properties on the surface of an eccentric sleeve is carried out.Conclusion on research work: - a decrease in the purge flow rate leads to an increase in the influence of the aerodynamic drag coefficient of the air on the movement of the parts of the molten particle, i.e. the time during which the molten metal is collected into the spherical part of the particle increases, therefore the diameter of the sprayed particles increases; - materials selected from copper and steel wire make it possible to obtain a coating of the surface of the sprayed part with high antifriction properties, which increases the strength and service life of the eccentric sleeve restored in the operation of the cone crusher; - in this paper, an alloy consisting of two metals is presented and studied, but today there are a huge number of possibilities in choosing various modern coatings used for parts operating under conditions of intense abrasive wear, significant shock loads, pressure, rolling, friction, sliding of metal surfaces. As an innovation in electroplating technology, it is proposed to continue research on a larger scale with further determination of stronger alloys.

Based on the information analysis, the briquetting process is defined as the optimal way to dispose of highly dispersed dust (HDD) of ferroalloy production. Initial studies have been conducted on the choice of a binder for briquetting (HDD). The obtained results showed the possibility of utilization of highly dispersed dust of Kazakhstan content by briquetting. As a binder, liquid glass and caustic soda were used in an amount of 10% by weight each. To ensure the necessary mechanical strength of briquettes, the pressing pressure below 40 kN seems impractical.

Serum vitamin D level is associated with the development of diabetic foot ulcer (DFU), and it is intriguing to determine if the vitamin supplementation could reverse the diabetic complication. The aim of this study was to investigate the efficacy of vitamin D supplementation in DFU management through qualitative and quantitative systematic review. A systematic search was conducted to screen the records identified in PubMed, Scopus, Embase, Scillit, Sci-Finder, LILACS, EuropePMC, medRxiv, bioRvix, Google Scholar, Semantic Scholar, and Garuda databases as of 10 March 2023. Studies investigating the efficacy of a single dose supplementation of vitamin D in DFU management were included. Quality of the included studies was appraised by Cochrane ‘Risk of Bias’ 2.0. Random-effects-based pooled analysis using Cohen’s d was performed on the wound healing progress as the primary outcome. A sensitivity test with leave-one-out method and meta-regression were also conducted to analyze the effect of heterogenous data. Five studies with a total of 245 patients (123 versus 122 for experimental and control groups, respectively) were finally included in the qualitative and quantitative analysis. The pooled estimate suggested that administering vitamin D to DFU patients could reduce the wound area or depth significantly as compared to control group (p<0.001; Cohen’s d: 2.72; 95% CI: 1.02 to 4.42). The value remained positive throughout the leave-one-out analysis. Vitamin D supplementation significantly contributed to the increased level of serum vitamin D (p=0.026, Cohen’s d: -0.719; 95% CI: -1.35 to -0.09). Elevation of high-density lipoprotein was observed in pooled estimate with p=0.016 and Cohen’d: 1.34 (95% CI: 0.25 to 2.44). Qualitatively, significant reduction of HbA1C, total cholesterol, and C-reactive protein were reported in at least two trials. Significantly improved quantitative insulin sensitivity check index (QUICKI) and decreased malondialdehyde, fructosamine, and fasting blood glucose were reported in at least one trial each. There were conflicting results on the change of low-density lipoprotein level. This study highlights that vitamin D supplementation promotes wound healing process among DFU patients; however, it is too premature to draw solid conclusions as the efficacy could be affected by multiple factors. Therefore, clinical trials from various demographics and ethnicities by using a high- versus low-dose model are needed.

Sustainable ecosystem services are increasingly recognized amid rapid regional transformation. While the rate of urbanization in China continues to rise, there is an urgent need to evaluate public preferences and their associated economic values concerning urban green space (UGS). The aim of this study was to calculate the overall willingness-to-pay (WTP) for UGS across China. Literature search was performed systematically on Scopus, Scilit, PubMed, and Google Scholar databases on 11 November 2023. Studies reporting the WTP in China were included in the analysis. Quality of the included studies were appraised by using Q-SSP tool consisting of 20-item quality of survey studies in psychology. To calculate the overall willing to pay rate and WTP, a meta-analysis was performed using restricted maximum-likelihood model on raw proportions. A total of nine studies were included comprised of 9381 valid responses with high quality according to Q-SSP (score: 70–90%). Findings from the meta-analysis indicated that the rate of willing to pay for UGS was 70.8% (95%CI: 60%, 82%; p-Het<0.001, I2= 99.37%). The rate was not affected by sample size, age, gender, and education (p>0.05). Among mainland Chinese population alone, the average minimum WTP was 2.97 USD/month, and increased to 3.36 USD/month if combined with Hong Kong population. A majority of over 70% Chinese population were willing to pay for UGS. Nevertheless, high heterogeneity in the pooled estimates suggest the importance of addressing contextual variables and presence of regional disparities.

In managing severe acute malnutrition (SAM) among children, the World Health Organization has endorsed the use of ready-to-use therapeutic foods (RUTF), especially the peanut and milk-based (PM-RUTF), which has been proven for its efficacy. Unfortunately, the distribution of PM-RUTF is challenged by high financial cost and reliance on imports for milk and peanuts. Researchers explore the Soy-Maize-Sorghum (SMS)-RUTF as the alternative, in which the formulation has two types; milk-free soya-maize-sorghum (FSMS)-RUTF and low milk content SMS (MSMS)-RUTF. The aim of this study was to evaluate the efficacy, safety, and acceptance of SMS-RUTFs in the management of SAM among children as compared with PM-RUTF. Eligible studies were searched through PubMed, Scopus, and Embase up to July 14, 2023. Studies reporting the effects of SMS-RUTF, FSMS-RUTF, or MSMS-RUTF intake on SAM with PM-RUTF as the control were considered eligible. The included randomized controlled trials were then assessed for the risk of bias using Cochrane Risk of Bias 2.0. Odds Ratio (OR) and mean difference (MD) were calculated using a random-effects meta-analysis. The analysis focused on investigating the recovery, mortality, weight gain, and hemoglobin levels. Five randomized controlled trials involving a total of 5,513 children were incorporated in this review. Of which, four studies were included in the statistical analysis. Those receiving SMS-RUTF was 0.77 times less likely to recover from SAM as compared to control (95% CI: 0.66–0.90, p<0.01). The SMS-RUTF group had 1 kg lower weight gain as compared to control (95% CI: -1.25–0.75, p<0.01). However, the SMS-RUTF group had significantly higher increase of hemoglobin level than control (MD: 0.80 g/dL [95% CI: 0.68–0.93], p<0.01). Adverse effects were observed similar in both SMS-RUFT and control groups. SMS-RUFT received low acceptance from the participants suspected to be caused by poor packaging. In conclusion, SMS-RUTF is less effective than PM-RUTF in managing SAM among children but can be used to improve anemia as indicated by increased hemoglobin levels.

Bacteria isolated from leachate with high heavy metal concentration mostly have potential for bioremediation. The aim of this study was to isolate bacteria from leachate of a landfill containing high concentration of Fe. The leachate sample was collected from Gampong Jawa Landfill, Aceh, Indonesia and used to isolate the bacteria by spread method. The purification of the isolates was carried out through four quadrant plate method. Pure isolates were characterized based on the microscopic or macroscopic appearance and biochemical tests. Fe-resistance was tested by disc diffusion method and constructing the growth curve based on the optical density of broth culture media. A total of 27 pure isolates were obtained and identified, representing eight different genera: Pseudomonas, Bacillus, Neisseria, Micrococcus, Staphylococcus, Proteus, Acinetobacter, and Escherichia. Of eight isolates (each genus was represented by a single isolate), Pseudomonas sp. and Bacillus sp. were considered resistant to Fe exposure (15 ppm) with inhibition zones of 1.00 and 0.81 mm, respectively. At Fe concentration of 20 ppm the inhibition zones exceeded 1 mm, but Bacillus sp. had smaller inhibition zone than that of Pseudomonas sp. (1.15 mm versus 2.86 mm). Growth inhibition of Bacillus sp. was concentration-dependent on Fe exposure but could survive at Fe exposure up to 20 ppm. In conclusion, Bacillus sp. had a resistance against Fe exposure and its bioremediation potential is subjected for future studies.
Avrupa Birliği Cezai Konularda Adli İşbirliği Birimi ile Avrupa Birliği Savcılığı Ofisi Arasındaki İşbirliği İlişkisi

Avrupa Birliği savcılığı (Abs), Avrupa Birliğinin mali çıkarlarına yönelik işlenen suçlar bakımından her bir üye devletin kendi bünyesindeki soruşturma birimlerinin yürüteceği soruşturmaların etkin ve süratli yürütülemeyeceği endişesiyle kurulmuştur. Avrupa Birliği Cezai Konularda Adli İşbirliği Birimi (Abib) ise Avrupa Birliği üye Devletleri arasında yargısal anlamda hızlı bilgi aktarım ağını tesis etmek adına kurulmuştur. Avrupa Birliğinin bu iki biriminin amacı neredeyse aynıdır. Zira Abs’nin kuruluşunda da kurumun Abib’den ayrılarak kurulduğunun belirtilmesi, her iki kurumun amaçlarının aynı olduğunu göstermektedir. Ancak Abib üye ülkelerin yargı mercileri arasında yatay bir işbirliğini öngörürken Abs dikey bir işbirliğini öngörmektedir. Bu nedenle her iki birim arasında işleyiş yönünden farklılıklar vardır. Bu iki birimin arasında hiyerarşik anlamda da bir bağ bulunmamaktadır; zira iki birim birbirinden bağımsız faaliyet göstermektedir. Abib ile Abs arasındaki ilişki bir çatışma değil işbirliği ilişkisidir. Düzenlemelere bakıldığında Abs’nin bilhassa Avrupa Birliğinin Mali Bütünlüğüne yönelik örgütlü ve sınır aşan suçlarda daha etkin bir rolü olsa da Abib’in de birliğe üye olmayan devletlerle olan anlaşması, öncelikli kullanım yetkisine sahip olduğu ağlar ve başka birtakım yetkileri dikkate alındığında her iki birimin birbirini tamamlayıcı özelliği olduğu söylenebilir. Bu makalede/çalışmada Avrupa Birliğinin bu iki birimi arasındaki işbirliği ilişkisi ele alınacaktır.
