Prevention of osteoporosis in population older than 50 from Colombia: An intervention model nutrieconomics perspective
Authors: Vélez-Cuellar Norida Nataly , Toloza-Perez Yesith Guillermo , Malagón-Rojas Jeadran
Published: November 2023

Introduction: Osteoporosis is a chronic disease characterized by a decrease in the density of bone mass, making bone more porous, less resistant and of lower quality than normal bone. This leads to the deterioration of its microstructure, making the bone more fragile and therefore increasing the risk of fracture. It has been found that high concentrations of Lactobacillus and Bifidobacterium promote the absorption of minerals such as calcium, magnesium, and phosphorus and thus increase mineral density. Due to the great social and economic impacts of osteoporosis, it is necessary to develop interventions that can be easily adopted at the population level, improving the quality of life of individuals without significantly affecting the health system. Objective: Assessing the impact of increased dairy consumption on the Colombian population diagnosed with osteoporosis between 2015 and 2020 through the simulation of the potential impact fraction (PIF). Methods: Using data from the Integrated Social Protection Information System (SISPRO) and National Nutritional Situation Survey (ENSIN), the incidence, the frequency of milk consumption, the potential impact fraction (PIF), and disability-adjusted life years (DALYs) were estimated. Results: A total of 63,640 cases of osteoporosis were identified. The highest incidence was observed in 2019. Seventeen food groups were identified in the ENSIN, and the most frequent products consumed by respondents over 50 years of age were milk, cheese, and yogurt. The PIF was then analysed, with a calcium intake of 600 mg/day, and a significant difference in the decrease in the number of cases was observed. In 2019, a higher estimated DALY loss of 9.9 was observed. In women, years of life lost due to fractures were the highest in the 65-69 age group. In men, they were highest in the 75-79 age group. Discussion: We observed that the departments with the highest consumption of dairy products were the capital of the country and regions where dairy products factories are located. It was not possible to establish an association between socioeconomic strata and low dairy intake. Nevertheless, some authors have proposed that westernization of diets and low income reduce access to fresh fruits and milk derivates. Conclusion: Years lost due to disability increased in the population over 60 years of age. In the PIF analysis, a decrease in cases was observed when the population increased consumption of dairy products.

Обʼєктом дослідження є процес вимірювання електроенергії цифровим трифазним лічильником. Мета – підвищення точності вимірювання електроенергії цифровим лічильником трансформаторного ввімкнення шляхом програмної інтеграції вимірювальних каналів. Запропоновано застосувати метод просторового вектора для вимірювання електроенергії. Пропонується вимірювати миттєві значення струмів та напруг трифазної електромережі за допомогою електромагнітних вимірювальних трансформаторів струму, виконувати аналого-цифрове перетворення для одержання цифрових відліків сигналів, обчислювати комплексні значення просторових векторів, знаходити повну потужність як добуток вектора напруги на спряжений вектор струму. Дійсна частина повної потужності відповідає активній потужності, уявна – реактивній. Шляхом інтегрування за часом обчислюються відповідні значення енергій. Перевагами такого підходу є відсутність необхідності обчислювати діючі значення струмів та напруг, що є одним з основних джерел невизначеності вимірювання. Також підвищення точності досягається за рахунок програмного об’єднання обчислень за трьома вимірювальними каналами. Застосування запропонованого підходу дає змогу знизити невизначеність вимірювання електроенергії, що підвищує точність розрахунків за спожиту електроенергію.
Дослідження імітації двовимірних вибірок з використанням поліноміальних сплайнів
Authors: Зівакін В.Д. , Приставка П.О.
Published: November 2023

Моделювання використовується для вирішення різноманітних завдань, через певний набір причин: імітація "критичних" режимів, що в умовах реальної експлуатації може бути небезпечним, економія часових і матеріальних ресурсів, можливість дистанційного тренінгу та ін. Зокрема, у випадку проведення досліджень у багатовимірних просторах, актуальним є не моделювання роботи системи, а саме послідовностей даних деякого визначеного вигляду могло б вирішити проблему нестачі таких даних.

В [1] сказано, що при імітаційному моделюванні вибірок перше, з чого необхідно виходити – це модель розподілу, яку необхідно отримати. Модель може бути визначена деяким аналітичним законом розподілу (нормальний, Вейбула, рівномірний, тощо), і в цьому вона залежать від параметрів (параметрична модель). Зазвичай обирають моделі такі, щоб їхні параметри несли деяку змістовну інтерпретацію ( початок та кінець інтервалу в рівномірному розподілі, інтенсивність в експоненціальному, тощо). Іншим класом моделей, що відтворюють функції розподілу є непараметричні (ядерні методи, гістограмні оцінки емпіричної функції розподілу, сплайн – апроксимація [4]). Основною проблемою методів, що ґрунтуються на параметрах, є обмеженість, особливо в двох випадках:

При моделюванні багатовимірних даних – в цьому випадку робота завжди призводить до переходу до багатовимірного нормального розподілу.

При моделюванні неоднорідних вибірок, які є сумішшю декількох розподілів (не обов’язково з одного класу), усічених або тих, що містять пропуски спостережень.

В цьому контексті використання параметричних моделей об’єктивно є неможливим у чистому вигляді. Отже, наявність інструменту, який добре апроксимує неоднорідні дані є бажаною для вирішення задачі генерації неоднорідних багатовимірних сукупностей.
Fostering language teachers’ intercultural awareness towards linguistic diversity and inclusion in education through COIL
Authors:   Florida Universitària, València, Spain, Cerveró-Carrascosa Abraham , Gazeley Zoe ,   Coventry University, UK
Published: November 2023

The following paper reports on a collaborative online learning experience (COIL) or virtual exchange (VE) between undergraduate students, pre-service teachers, from Coventry University in the UK and Florida Universitària in València, Spain. The exchange was embedded in two modules in each institution and aimed to foster critical views on multilingual policies and interculturality in English as a foreign language teacher education (MIEFOLTE). The participants were grouped in breakout rooms where they engaged in discussions on the topics of social equity, linguistic diversity, and inclusion in education. In addition, their group reflections were posted on a digital noticeboard during the synchronous sessions. The outcomes seem to illustrate how MIEFOLTE provided students with opportunities for critical reflection and made students aware that they had developed their Intercultural Communicative Competence (ICC) and how to transfer it to their future professional practice.
Valorisation du Capital Immatériel par le Marché Financier : Une Analyse Empirique sur le Marché Financier Régional de l’UEMOA
Authors: Ossonon Ahou Claudine
Published: November 2023

L’objectif de ce papier est d’analyser la valorisation du capital immatériel par le marché financier. L’analyse de régression sur des données de 20 entreprises cotées sur le Marché Financier Régional prouve que les informations liées au capital structurel publiées dans les rapports annuels sont valorisées positivement par les investisseurs. Toutefois, nonobstant la politique de communication soutenue des entreprises en matière de capital humain, le capital humain est valorisé négativement par le marché financier. Le marché financier ne perçoit pas le capital humain comme étant un facteur clé de création de valeur et de compétitivité. Relativement au capital relationnel, aucune relation n’a été mise en exergue. Eu égard aux conclusions de cette recherche empirique, les dirigeants d’entreprises cotées doivent communiquer davantage des informations pertinentes et suffisantes aux investisseurs sur le marché financier sur les différentes composantes du capital immatériel pour une meilleure valorisation de leurs titres. D’ailleurs, l’originalité de cette étude réside dans le fait qu’elle est la première recherche à fournir une preuve empirique de la valorisation, par les investisseurs sur le marché financier régional, des informations extra financières communiquées sur les composantes du capital immatériel dans les rapports annuels des entreprises cotées.

 

The objective of this paper is to analyze the valuation of intangible capital by the financial market. Regression analysis on data from 20 companies listed on the Regional Financial Market proves that information related to structural capital published in annual reports is positively valued by investors. However, notwithstanding the sustained communication policy of companies in terms of human capital, human capital is negatively valued by the financial market. The financial market does not perceive human capital as a key factor in creating value and competitiveness. Regarding relational capital, no relationship has been highlighted. Given the conclusions of this empirical research, managers of listed companies must communicate more relevant and sufficient information to investors in the financial market on the different components of intangible capital for a better valuation of their securities. Moreover, the originality of this study lies in the fact that it is the first research to provide empirical proof of the valuation, by investors on the regional financial market, of extra-financial information communicated on the components of intangible capital. in the annual reports of listed companies.

Authors: Cabral Augusto Cézar de Aquino
Published: November 2023

Este ensaio constitui uma reflexão sobre a Análise do Discurso (AD), que vem ocupando um espaço cada vez mais significativo nos estudos organizacionais em geral e na administração em particular. Ele inicia-se com a apresentação de suas correntes principais, uma divisão metodológica que delimita orientações distintas tanto no campo teórico quanto no prático. Toma-se como ponto de partida no embasamento teórico as contribuições de Saussure. Posteriormente, as teorias de atos de fala, ou pragmáticas, assim como as teorias de enunciação e o conceito de destinaridade são brevemente explorados, como forma de fixar um referencial que guie o leitor e o permita compreender a premência de se submeter o discurso da administração às indiscretas lentes da AD.

Authors: Puspitasari Belia
Published: November 2023

Waxy corn (Zea mays var. ceratina) has a shiny white color like wax because of its high amylopactin content. The use of chemical fertilizers can cause soil health to be disturbed and result in a decrease in cultivation yields. The use of organic fertilizers such as bokashi fertilizers and biological fertilizers is expected to be a solution in overcoming problems related to soil fertility and can increase cultivation yields. The purpose of this study was to determine the dosage of bokashi fertilizer and the concentration of biological fertilizers, as well as their interaction with the growth and yield of waxy corn. The study used a randomized block design consisting of 2 factors with 4 treatment levels, repeated 3 times. The first factor was the dose of bokashi fertilizer (A), which consisted of 4 levels, namely 0 tons/ha (A0), 15 tons/ha (A1), 20 tons/ha (A2), and 25 tons/ha (A3). ). The second factor was the concentration of biological fertilizers (B) which consisted of 4 levels namely, 0ml/L (A0), 15ml/L (A1), 20ml/L (A2), and 25 ml/L (A3). Further data were analyzed using analysis of variance. If the treatment parameters are significantly different, then the DMRT test is carried out with a level of 5%. The results showed that the interaction between the application of bokashi and biological fertilizers gave significantly different results on plant height and leaf area index. The dose of bokasi fertilizer had a significant effect on the length of the fruit with the husk, the length of the fruit without the husk, the weight of the fruit with the husk, the weight of 1000 seeds, the weight of the wet stover and the weight of the dry stover. Concentration of biological fertilizers significantly affected fruit diameter with husk, fruit weight with husk, fruit length without husk, fruit diameter without husk, fruit weight without husk, wet stover weight, and dry stover weight.

Aim: Receptor activator of nuclear factor-kappa B (RANK)-containing extracellular vesicles (EVs) bind RANK-Ligand (RANKL) on osteoblasts, and thereby simultaneously inhibit bone resorption and promote bone formation. Because of this, they are attractive candidates for therapeutic bone anabolic agents. Previously, RANK was detected in 1 in every 36 EVs from osteoclasts by immunogold electron microscopy. Here, we have sought to characterize the subpopulation of EVs from osteoclasts that contains RANK in more detail. Methods: The tetraspanins CD9 and CD81 were localized in osteoclasts by immunofluorescence. EVs were visualized by transmission electron microscopy. A Single Particle Interferometric Reflectance Imaging Sensor (SP-IRIS) and immunoaffinity isolations examined whether RANK is enriched in specific types of EVs. Results: Immunofluorescence showed CD9 was mostly on or near the plasma membrane of osteoclasts. In contrast, CD81 was localized deeper in the osteoclast’s cytosolic vesicular network. By interferometry, both CD9 and CD81 positive EVs from osteoclasts were small (56-83 nm in diameter), consistent with electron microscopy. The CD9 and CD81 EV populations were mostly distinct, and only 22% of the EVs contained both markers. RANK was detected by SP-IRIS in 2%-4% of the CD9-containing EVs, but not in CD81-positive EVs, from mature osteoclasts. Immunomagnetic isolation of CD9-containing EVs from conditioned media of osteoclasts removed most of the RANK. A trace amount of RANK was isolated with CD81. Conclusion: RANK was enriched in a subset of the CD9-positive EVs. The current study provides the first report of selective localization of RANK in subsets of EVs.
Cooperative search for moving targets with the ability to perceive and evade using multiple UAVs
Authors: Wang Ziyi , Guo Jian , Zou Wencheng , Li Sheng
Published: November 2023

This paper focuses on the problem of regional cooperative search using multiple unmanned aerial vehicles (UAVs) for targets that have the ability to perceive and evade. When UAVs search for moving targets in a mission area, the targets can perceive the positions and flight direction of UAVs within certain limits and take corresponding evasive actions, which makes the search more challenging than traditional search problems. To address this problem, we first define a detailed motion model for such targets and design various search information maps and their update methods to describe the environmental information based on the prediction of moving targets and the search results of UAVs. We then establish a multi-UAV search path planning optimization model based on the model predictive control, which includes various newly designed objective functions of search benefits and costs. We propose a priority-encoded improved genetic algorithm with a fine-adjustment mechanism to solve this model. The simulation results show that the proposed method can effectively improve the cooperative search efficiency, and more targets can be found at a much faster rate compared to traditional search methods.
THE PSYCHOMETRIC FEATURES OF THE QUIET EGO SCALE AND THE CONSTRUCT VALIDITY OF THE QUIET EGO
Authors: Đorđević Ana
Published: November 2023

The concept of quiet ego is conceived as a personal identity that transcends selfishness
without ignoring personal interest at the same time. It is measured through a scale consisting
of 14 items. The limited scope of research on this concept in psychological literature, as well
as the absence of research for the Macedonian population, is the main motive for this research.
This research aims to examine the psychometric properties of the Quiet Ego Scale and the
validity of the construct of Quiet Ego (Quiet Ego Scale, Waymet, Bauer & Slaskia, 2014). Two
studies were conducted for the purposes of the study. The first study is a correlational one, in
which, in addition to the Quiet Ego Measurement Scale, instruments for measuring of
narcissism (Narcissism Measurement Inventory, Raskin & Terry, 1988) and of empathy
(Toronto Empathy Questionnaire, Spreng et al, 2009) are been set. In this study the analysis of
the main components also take part. The results have shown that the Quiet Ego Scale has
satisfactory internal homogeneity and a factor structure that confirms the theoretical solution
of the construct, as well as a significant correlation with concepts similar and contrary to the
researched concept. Using an experimental design, in the second study the levels of narcissism
and empathy were manipulated (increased narcissism vs. reduced narcissism and increased
empathy versus reduced empathy), in order to investigate the impact of different levels of
narcissism and empathy on the level of quiet ego. The results of the second study confirmed
the relationship between quiet ego, narcissism and empathy and justification for using the
construct of the quiet ego.

Advanced Processing of 2D Marine Reflection Seismic Data Using the Common Reflection Surface (CRS) Stack Method with K-L Filter Application
Authors: Zein Emir Dzakwan Kamal , Rasimeng Syamsurijal , Wijaksono Egie
Published: November 2023

Data processing using the seismic reflection method is an important stage in the exploration of natural resources and minerals. This research was conducted to determine the effective and efficient stacking and filtering methods in reconstructing the subsurface geological structure of the earth from the results of data processing using ProMAX software. The data processing method used is the conventional stack and the Common Reflection Surface (CRS) stack. Aperture values of 0 ms – 50 m and 3000 ms – 150 m in the CRS stack process produce the most optimum seismic sections. Both methods produce a different quality of seismic cross-section display. The 2D cross-section model from the conventional stack method looks noisier than the results from the CRS stack method. In addition, the reflector pattern on the cross-section of the results of the CRS stack method is clearer and visible with a relatively large amplitude compared to the results of the conventional stack method. To maximize the quality of data display, data enhancement is applied, which is the K-L filter. The eigenimages value of 0.10% on the K-L filter with a horizontal window width of 120 is used to reduce random noise. Thus, an increase in the S/N ratio will be obtained in the seismic data so that the 2D cross-sectional model of the seismic reflection method can approach the original conditions of the subsurface geological structure.

Published: November 2023

The Kei Besar Island is mainly composed of the Elat Formation carbonate rocks. This research was conducted to determine the nannofossils assemblages in the Elat Formation to interpret the depositional dynamics during its formation. Lithological observations and sampling for nannofossil analysis were carried out on three measured stratigraphic sections: Section 1 - Hollat, Section 2 - Ngurdu, and Section 3 - Mata Hollat. A total of 47 species assigned to 25 genera of nannofossils were identified in 45 selected samples. The succession of the Elat Formation in the study area formed at NP16 to N17 or Middle Eocene. Stratigraphic reconstruction supported by biostratigraphy analysis shows that Section 3 at the lower (NP16 to NP 17), Section 2 in the middle part (NP 17), and Section 1 at the upper (NP 17). R-mode cluster analysis of nannofossils defined four species clusters (assemblies A, B, C and D) that tend to occur together. Q-mode cluster analysis defined five depth-distribution clusters (1, 2, 3, 4, and 5), each deposited under similar conditions. Based on large foraminifera, the succession was formed in fore reef setting in neritic bathymetric zone. Coarsening and thickening upward supported by the nannofossil assemblages indicate depositional dynamics which tend to be shallower. Reworked fossils, commonly found at the lower of the Elat Formation, show the mechanism of turbid currents in early deposition.

Published: November 2023

Seismic migration is one of the important stages in seismic data processing which aims to map seismic events to their actual positions. The migration process used in this study is post-stack time migration in the time domain using the Kirchhoff migration technique and the finite difference method to determine the results of subsurface imaging from the two migration techniques and then compare them to determine the accuracy of selecting the appropriate migration for the L08 basin trajectory research area. Nias basin, North Sumatra. The processing steps are carried out according to the preprocessing to processing stages in the Promax 5000 software. Based on the results of the study, the optimum use of aperture migration in Kirchhoff migration will produce good subsurface cross-sectional imaging. The aperture value used is 3000 ms. In the finite difference migration, subsurface imaging is much more focused with a time step variation of 10 ms, whose function is to focus the hyperbolic diffraction energy on the migration data.

Published: November 2023

Bengkulu is the capital of Bengkulu Province and is located in the subduction zone between the Eurasian and Indo-Australian plates. Bengkulu is also close to the major faults of Sumatra, namely the Musi fault, the Ketahun fault, and the Manna fault. Therefore, regional planning and infrastructure development for earthquake mitigation is necessary. The purpose of this study is to estimate the thickness of the sedimentary layers in the construction zone of Bengkulu Hospital during the earthquake attenuation phase. This study is conducted by surface geological analysis using the HVSR method; data analysis using microtremor data. The microtremor data were analyzed using the HVSR method to obtain the amplification value (A0) and the dominant frequency (f0). HVSR analysis gave dominant frequency (f0) values from 5.1 to 5.8 Hz, amplification (A0) from 1.64 to 5.91 times, and dominant period (T0) from 1.49 to 2.81 seconds. The values of A0, f0, T0 are interpreted with reference to the literature and surface geology as a moderate risk of seismic vulnerability, characterized by moderate to weak sedimentation and moderate amplification values.

The results of this study can be concluded that Pungguk Pedaro Village is dominated by Clay, Sandstone, Sandy Gravel, Andesite, Basalt, and Granite rocks. Line 1 has no potential for hydrothermal distribution because there has been a mixture of hydrothermal water with mountain water, so only groundwater is obtained on this line.
Diversity of bacterial symbionts associated with the tropical plant bug Monalonion velezangeli (Hemiptera: Miridae) revealed by high-throughput 16S-rRNA sequencing.
Authors: Navarro-Escalante Lucio , Benavides Pablo , Acevedo Flor Edith
Published: November 2023

Insects and microbes have developed complex symbiotic relationships that evolutively and ecologically play beneficial roles for both, the symbiont and the host. In most Hemiptera insects, bacterial symbionts offer mainly nutritional, defense and reproductive roles and have promoted the adaptive radiation of several hemipteran phytophagous lineages. The tropical plant bug Monalonion velezangeli (Hemiptera: Miridae) is a polyphagous herbivore considered an important insect pest for several economically-relevant tropical crops; however, information about the composition of its bacterial microbiota was missing. In this study, we describe the diversity and structure of the bacterial microbiota in the nymph and adult life stages of M. velezangeli using Illumina high-throughput sequencing of 16S ribosomal RNA gene amplicons (meta-barcoding). We found that both insect life stages share a similar microbiota in terms of bacterial diversity and community structure. The intracellular symbiont Wolbachia (~92%) dominated the overall microbiome composition in these life stages, and along with bacteria genera Romboutsia, Ignavibacterium, Clostridium, Allobaculum, Paracoccus, Methylobacterium, Faecalibacterium, Collinsella, Rothia, Sphingomonas and other 4 undetermined genera, were found as members of the core microbiota. Based on PCR screening and DNA sequencing of wsp gene, Wolbachia infection was confirmed in almost 80% of samples, represented by two different isolates or strains within the supergroup B. This data opens new questions and avenues to better understand the contribution of symbiotic bacteria in the biological performance of this insect pest and provide bases to explore other insect control methods.
Accepting the Process, Rejecting the Outcome – A Fairness Paradox in Judging Wealth Distributions
Authors: Sikström Sverker , Roine Jesper
Published: November 2023

How wealth accumulates following investments is a fundamental process in our society, as is people’s understanding and acceptance of such processes. We show a fairness paradox, where people view an underlying wealth accumulation process as fair, but the outcome from it as completely unfair. This suggests that people misjudge how wealth accumulation works, and that they may be lured into accepting unfair outcomes based on premises they view as fair, but do not understand the consequences of.

This paper reports the discovery that water can trigger a peculiar nuclear-like reaction and produce energy. Cavitation may induce unusual reactions through implosion of water vapor bubbles. Many of this research has been published formally or informally1-10. We have conducted experiments using two reactor types made from multiple-pipe heat exchanger and found that the heat exchange process of water produces peculiar excess heat and abnormally high pressure leading to rupture of the reactor11. Recently, we have tested another eight reactors. Interestingly, these reactors produce non-condensable gas. We suspected that they include Ne22 and CO2 .
We used a mass spectrometer (MS) to analyze 14 gas samples collected from 8 reactors, including ten reactors showing a coefficient of performance COPx >1.05 (with excess heat) and four having COPx < 1.05 (without excess heat). Several methods were adopted to identify the gas content. For CO2 identification, two methods are employed. For Ne22 identification, three methods are employed. All the results confirm that isotope Ne22 and regular CO2 really exist in the output gas from reactors determined to have excess heat.
We conjecture a possible mechanism to produce Ne22 and CO2 and find out that C12 and isotope O17 are the intermediate. They finally form isotope gases containing O17, including H2O-17 (heavy-oxygen water), isotope O2 (O16-O17), and isotope CO2 (C12-O16-O17). In the excess heat producing reactors, all these gasses were detected by MS in the absence of Ne20 and Ne21. The observed isotope gases produced from reactors having excess heat verifies that water can trigger a peculiar nuclear-like reaction and produce energy.

Design: The BaSES (Basel Starch Evaluation in Sepsis) Trial is an investigator-initiated, single-centre, randomised controlled clinical trial on volume resuscitation.
Setting: We investigated whether volume resuscitation with Hydroxyethyl starch (HES 130/0.4) compared to normal saline (NaCl 0.9%) reduces ICU length of stay.
Patients: A total of 244 septic shock patients were randomized (119 to HES, 125 to NaCl).
Interventions: Randomization to HES or NaCl for volume resuscitation.
Measurements: ICU length of stay (LOS), hospital LOS, ICU mortality, in-hospital mortality, and 1-year mortality, incidence of acute kidney injury (AKI), fluid balance, trajectory of inflammatory parameters, lactate, and SOFA (sequential organ failure assessment) score.
Main results: Baseline characteristics and ICU management were comparable among groups. ICU LOS was not significantly shorter with HES (hazard ratio, HR, for ICU discharge alive HES vs. NaCl, 1.11,95% CI 0.83 to 1.49). However, the HES group showed a significantly reduced hospital LOS (HR HES vs. NaCl: 1.48, 95 % CI 1.09 to 2.01, p=0.011). HES did not significantly affect other laboratory values, mortality or renal function.
Conclusions: The results of the BaSES trial neither do call for complete suspension of HES from the market, nor do they support a role of HES in volume resuscitation in septic shock.

The operation of reservoir flood control operation is a multifaceted engineering issue characterized by complexity, several stages, nonlinearity, and many dimensions. It involves various intricate constraints and interrelated decision variables. Traditional algorithms tend to be slow and prone to local optima when solving optimization problems for flood control in reservoir groups. In recent years, with the introduction of various optimization technologies, more intelligent algorithms have been applied to optimize reservoir flood control scheduling problems in recent years. However, this remains a challenging task for large-scale reservoir group optimization scheduling problems. This work utilizes an Improved Grey Wolf Optimisation algorithm (IGWO) that incorporates Levy fly and random walk techniques for more effective optimization and scheduling of reservoir groups. Taking the Xiaolangdi Reservoir, Sanmenxia Reservoir, Luhun Reservoir, and Guxian Reservoir in Yellow River's middle and lower reaches as examples, a flood control dispatch system composed of four series and parallel reservoirs and a downstream control point at Huayuankou is studied as an example. We have established a flood control optimization scheduling model based on the Huayuankou control object, which maximizes the reduction of peak flow, and compared and analyzed the optimization results of the Improved Grey Wolf Algorithm (IGWO), Grey Wolf Algorithm (GWO), and Particle Swarm Optimization Algorithm (PSO). The results show that the Improved Grey Wolf Optimization algorithm achieves the best performance in calculating the maximum peak flow rate at Huayukou, with a peak flow rate of 18,681.1 m3/s and a peak reduction rate of 50.68%. This research offers novel perspectives and methodologies for addressing the optimization scheduling of reservoir clusters in flood control operations.

Published: November 2023

In this work, a multiple nonlinear vibration model of drilling string system in ultra-HPHT oil & gas wells was established using finite element method, energy method and Lagrange equation, which considers multiple nonlinear factors such as the nonlinear effect of ultra-HPHT on the elastic modulus of the drill string, the nonlinear contact between the drill string and the borehole wall, and the longitudinal transverse torsional coupling vibration of the drill string structure. The incremental form Newmark and Newton Raphson joint iteration methods is proposed and the correctness of the model is verified by the field test data. Based on the mechanism of the torsion impact acceleration tool, corresponding motion equations are established and the main ways of acceleration were determined. Based on this, according to the parameters of YC ultra-HPHT well in South China Sea, the influence of the impact tool on the vibration characteristics and stick slip characteristics of the drill string were explored. It is found that, firstly, applying constant torque can effectively reduce the time for the drill string to stall and improve the mechanical drilling speed of the drill bit. The sine wave torque excitation has the best effect and can effectively improve the mechanical drilling speed. Secondly, with the increase of torque amplitude, the peak speed decreases significantly, the torsional vibration of the drill string becomes more stable, and the viscosity time of stick slip vibration also decreases significantly. Under the premise of meeting the safety of the acceleration tool, a torque amplitude of 4000 N·m can be used for acceleration, which has a better acceleration effect. Thirdly, the torque frequency increases, the peak speed shows a trend of first decreasing and then increasing, while the viscosity time also shows a trend of first decreasing and then increasing. This indicates that the optimal acceleration effect is achieved when the frequency of acceleration tool is selected to be around 20 Hz. The research results provide a theoretically guidance for designing and practically sound approach for effectively improving the mechanical speed in ultra-HPHT oil & gas wells.

BackgroundPublic health centres (PHCs) as primary healthcare in Indonesia were pivotal in handling COVID-19 detection, management, and reporting. Limited studies show various findings on COVID-19 management and its impact on further health risks, particularly in vulnerable populations like children under five years.MethodsThis cross-sectional study assessed secondary data from tracing reports, patient medical records, and integrated management childhood illness reports. Samples were collected using stratified random sampling based on three age groups (< 1 year, 1-3 years, 3-5 years) and the period of COVID-19 infection (2020, 2021, 2022) from ten district PHCs in East Jakarta. The collected data was analysed for descriptive, bivariate, and multivariate statistical analysis using IBM SPSS 26thversion.Results677 patients were included in this study, with the majority from 2021 (44.2%) with age 28 [0-60] months and male patients (52.6%). Only 4.14% of them have available records of vaccination history in PHC, so the risks of further respiratory problems based on vaccination status were not feasible to assess. 23.63% of them received the COVID-19 medications, with the most frequently prescribed vitamins-supplements (27.96%) and cough-related medications (12.17%). Patients with medications have fewer visits to PHCs in one semester after COVID-19 (U=-2,728, p=0.006). Acute upper respiratory infection was the most prevalent (30.32%) reason for patients' revisits after COVID-19 infection, and there were also reinfection cases of COVID-19 (4.52%). The risks of respiratory problems have no significant difference between age group, gender, and COVID-19 treatment history. The lack of complete and integrated data availability has become a hurdle to further analysis.ConclusionA small proportion of children under five years were receiving COVID-19 medication in PHCs and it poses a potential impact of decreasing further patient encounters with healthcare. There is a need for better health data management and integration in PHCs to be used as comprehensive assessments of community health risks, particularly for special populations.

Background The COVID-19 pandemic was associated with increased morbidity and high mortality due to the Sars-Cov-2 virus, but the pandemic also influenced health behaviors such as physical activity (PA) and alcohol consumption. The aim of this study was to examine potential changes in leisure PA and alcohol consumption in Sweden during the pandemic, and to explore whether identified changes varied between sex, age groups and socioeconomic status (SES). Methods Data were retrieved from two waves of the longitudinal cohort study Life conditions, Stress and Health (LSH) (n = 2,523). Two measures of change were used; longitudinal change relative to baseline (2012–2015) and reported change compared to before the pandemic. For these two change measures, differences between sex, age group and SES were analyzed using multinomial logistic regression. Results Irrespective of change measure, the proportion with decreased PA was larger among women than men. Also, relative to baseline, women were less likely to having increased PA. However, according to the reported change relative to before the pandemic, women were more likely to have increased PA. Longitudinal change in PA compared to baseline followed a reversed age gradient, while, according to reported change, a decrease in PA during the pandemic was most prevalent in respondents 45 years of age at baseline (OR = 1.8, CI: 1.2–2.5) and respondents 50 years of age at baseline (OR = 1.7, CI: 1.2–2.4). High SES was associated with a greater variability in PA. Alcohol consumption was generally reduced during the pandemic. However, individuals aged 40 or 45 years at baseline were more likely than others to have initiated risky alcohol consumption. Conclusions Women were more likely to change their PA levels during the pandemic. The most profound decreases in PA were found in individuals of working ages. Although the pandemic led to a general decrease in alcohol consumption, individuals aged 40 and 45 were more likely than other ages to have initiated risky alcohol consumption. In conclusion, societal restrictions during a pandemic pose a risk for decreased PA among individuals in working ages, but can also open a window of opportunity, not least for women, to increase their PA levels.

Lead (Pb2+) toxification in society is one of the most concerning public health crises that remains unaddressed. The exposure to Pb2+ poisoning leads to a multitude of enduring health issues, even at the part-per-billion scale (ppb). Yet, public action dwarfs its impact. Pb2+ poisoning is estimated to account for 1 millions deaths per year globally, which is in addition to its chronic impact on children. With their ring-shaped cavities, crown ethers are uniquely capable of selectively binding to specific ions. In this work, for the first time, the synergistic integration of highly-scalable silicon photonics, with crown ether amine conjugation via Fischer esterification in an environmentally-friendly fashion is demonstrated. This realizes a photonic platform that enables the in-situ, highly-selective and quantitative detection of various ions. The development dispels the existing notion that Fischer esterification is restricted to organic compounds, laying the ground for subsequent amine conjugation for various crown ethers. In this work, the platform is engineered for Pb2+ detection, demonstrating a large dynamic detection range of 1–262000 ppb with high selectivity against a wide range of relevant ions. These results indicate the potential for the pervasive implementation of the technology to safeguard against ubiquitous lead poisoning in our society.
