Authors: Gao Haoran , Gong Jian , Yang Jianxin , Liu Jiakang , Ye Teng
Published: June 2023

Understanding the process of land use/cover changes (LUCC) can provide experience on the enhancement of soil organic carbon(SOC) stocks and carbon sequestration potential for different areas. We divided Qinghai Province into four functional areas and used machine learning method and soil carbon pool dataset to compare and analyze the drivers of LUCC and the changes in SOC stocks effected by LUCC. Topography and climate changes are the main drivers affecting LUCC in four natural areas, while soil factors and population changes do not cause significant effects. The total SOC stocks in Qinghai was increased by 71.18 Tg C and 107.19 Tg C in 0-30cm and 0-300cm layers, respectively, and the highest SOC stocks within 0-300cm were in Pastoral area. Desert and Gobi area had the lowest SOC stocks in both 0-30cm and 0-300cm layers. SOC stocks increased in both 0-30cm and 0-300cm layers only in Sanjiangyuan Natural Reserve, while the Desert and Gobi area showed a decrease in both over 30 years. Grassland changes caused a significantly SOC stocks changes. The initial and original SOC stocks of pre-LUCC may influence the SOC stocks in post-LUCC. The response of SOC stocks changes to LUCC was varies in different areas.

Background Obese patients have been found to be susceptible to iron deficiency, and malabsorption of dietary iron is the cause of obesity-related iron deficiency (ORID). Divalent metal transporter 1 (DMT1) and ferroportin (FPN), are two transmembrane transporter proteins expressed in the duodenum that are closely associated with iron absorption. However, there have been few studies on the association between these two proteins and the increased susceptibility to iron deficiency in obese patients. Chronic inflammation is also thought to be a cause of obesity-related iron deficiency, and both conditions can have an impact on spermatogenesis and impair male reproductive function. Based on previous studies, transgenerational epigenetic inheritance through gametes was observed in obesity. Results Our results showed that obese mice had decreased blood iron levels (p < 0.01), lower protein and mRNA expression for duodenal DMT1 (p < 0.05), but no statistically significant variation in mRNA expression for duodenal FPN (p > 0.05); there was an increase in sperm miR-135b expression (p < 0.05). Bioinformatics revealed ninety overlapping genes and further analysis showed that they were primarily responsible for epithelial cilium movement, fatty acid beta-oxidation, protein dephosphorylation, fertilization and glutamine transport, which are closely related to spermatogenesis, sperm development and sperm viability in mice. Conclusions In conclusion, this study demonstrated that high-fat diet impairs male fertility by disrupting DMT1 and miR-135b in the gut-testis axis.

Lately, many creative people are using Crowdfund-ing to raise money for their ideas through the use of an online platform. The use of third-party middlemen who cannot guarantee the investor’s money and the lack of investor control over how their money is used are two issues with the current crowdfunding approach. On the other hand, blockchain technology is a safe, trustworthy , and decentralized network that has become highly popular across many varieties of organizations due to its effectiveness when compared to more traditional ways. However, older techniques have a lot of issues and challenges because of their complex and less secure networks. We can address and avoid these issues if we start incorporating blockchain technology. Blockchain technology can be used to address these problems since it provides benefits including increased security, transparency, efficiency, and reduced fraud risk. Here, we propose a new crowdfunding platform based on blockchain innovation that provides a decentralized and transparent process. By enabling users to construct smart contracts that give them control over the invested cash, our platform’s major objective is to give investors the ability to successfully contribute to any private or public project. In our research, we have highlighted the variations between blockchain-based and traditional crowdfunding platforms and the advantages of using blockchain for various industries. We also discuss the challenges that established sectors face and how blockchain-based platforms could potentially help to address these challenges.

Authors: Faraj Raid , Diallo Thierno Hamidou , Abdelali Mehdi , Benmessaoud Fatima-azzahra , Doghmi Nawal , Zarzur Jamila , Cherti Mohamed
Published: June 2023

Background: Acromegalic cardiomyopathy is a significant cardiovascular complication associated with acromegaly, a rare condition caused by excessive growth hormone production from a pituitary adenoma. While acromegaly often presents with distinct physical changes, early diagnosis can be challenging due to its insidious nature, leading to delayed recognition and the presence of multiple comorbidities at the time of diagnosis. Cardiovascular disease is the most common comorbidity in acromegaly, contributing to significant morbidity and mortality.
Case presentation: This case report describes a non-hypertensive patient who presented with biventricular hypertrophy, revealing the presence of acromegalic cardiomyopathy at the age of 54. The diagnosis relied on information from clinical examination, imaging tests, and biological data. The patient successfully underwent transsphenoidal surgery to remove the pituitary adenoma, resulting in a positive outcome.
Conclusions: Acromegaly patients have higher mortality rates compared to healthy individuals due to the wide array of associated comorbidities, consequently leading to a reduced life expectancy. Hence, early diagnosis and management, particularly before the age of 40, play a crucial role in mitigating the cardiovascular risks associated with acromegaly.
Machine Learning Models to Predict Kidney Stone Recurrence Using 24 Hour Urine Testing and Electronic Health Record-Derived Features
Authors: Doyle Patrick , Gong Wu , Hsi Ryan , Kavoussi Nicholas
Published: June 2023

Objective
To assess the accuracy of machine learning models in predicting kidney stone recurrence using variables extracted from the electronic health record (EHR).
Methods
We trained three separate machine learning (ML) models (least absolute shrinkage and selection operator regression [LASSO], random forest [RF], and gradient boosted decision tree [XGBoost] to predict 2-year and 5-year symptomatic kidney stone recurrence from electronic health-record (EHR) derived features and 24H urine data (n = 1231). ML models were compared to logistic regression [LR]. A manual, retrospective review was performed to evaluate for a symptomatic stone event, defined as pain, acute kidney injury or recurrent infections attributed to a kidney stone identified in the clinic or the emergency department, or for any stone requiring surgical treatment. We evaluated performance using area under the receiver operating curve (AUC-ROC) and identified important features for each model.
Results
The 2- and 5- year symptomatic stone recurrence rates were 25% and 31%, respectively. The LASSO model performed best for symptomatic stone recurrence prediction (2-yr AUC: 0.62, 5-yr AUC: 0.63). Other models demonstrated modest overall performance at 2- and 5-years: LR (0.585, 0.618), RF (0.570, 0.608), and XGBoost (0.580, 0.621). Patient age was the only feature in the top 5 features of every model. Additionally, the LASSO model prioritized BMI and history of gout for prediction.
Conclusions
Throughout our cohorts, ML models demonstrated comparable results to that of LR, with the LASSO model outperforming all other models. Further model testing should evaluate the utility of 24H urine features in model structure.
Transient analysis of earthing electrodes considering soil ionization phenomenon under lightning impulse condition
Authors: Sengar Kaushal Pratap , Chandrasekaran Kandasamy
Published: June 2023

This paper presents the transient behavior of an earthing system under the influence of lightning current injected in to it. Vertical rod and horizontal electrode buried in homogeneous soil are considered in this analysis. State-space representation based transmission line methodology is adopted with non-linear parameters for modelling the earthing electrodes in the time domain. Soil ionization phenomenon is taken up with the presence of residual resistivity. In this method, soil resistivity variation is adopted to evaluate the soil ionization phenomenon that occurs due to changes in the electric field. This study incorporates mutual coupling between the electrode segments for low and high soil resistivity. Earthing electrodes are subjected to a high-magnitude of lightning current impulse with different peaks. Transient voltage and impulse impedance are calculated to analyse the transient behaviour of earthing electrodes with soil ionization. Impulse impedance of vertical earthing rods and horizontal electrodes are calculated and compared with the power frequency impedance. Percentage ohmic reduction between them is also reported. The influences of critical electric field, soil resistivity and lightning magnitude on transient performance of earthing electrodes are calculated. Also, an effect of the front time of lightning current impulse for a fixed peak on the impedance of the earthing electrode is evaluated and a significant amount of changes are observed. Simulated results are validated with the experimental and theoretical results reported in the literature, and good agreements are found.

Background
Spaceflight is physically demanding and can negatively affect astronauts’ health. It has been shown that the human gut microbiota and cardiac function are affected by spaceflight and simulated spaceflight. This study investigated the effects of the gut microbiota on simulated spaceflight-induced cardiac remodeling using 10 degrees of head-down bed rest (HDBR) in rhesus macaques and 30 degrees of hindlimb unloading (HU) in mice.
Results
In macaques, the gut microbiota, fecal metabolites, and cardiac remodeling were markedly affected by HDBR, and there was a correlation between cardiac remodeling and the gut microbial-derived metabolite trimethylamine N-oxide. The gut microbiota and fecal metabolites in mice were also markedly affected by HU and correlated with cardiac remodeling. Cardiac remodeling in control mice was affected by the gut microbiota of HU mice and that of HU mice was protected by the gut microbiota of control mice.
Conclusion
The gut microbiota, fecal metabolites, and cardiac remodeling were markedly affected by HDBR in macaques and HU in mice. These results are consistent with the known effects of spaceflight and HDBR in humans. Cardiac remodeling was affected by the gut microbiota under simulated spaceflight conditions, and the gut microbial-derived trimethylamine N-oxide was correlated with cardiac remodeling. These findings suggest that spaceflight can affect cardiac remodeling by modulating the gut microbiota and fecal metabolites.

Published: June 2023

Stable isotopic compositions of carbon and nitrogen (δ13C, δ15N) of archaeological grains/seeds recovered from different cultural layers of an Indus archaeological site 4MSR (29°12'87.2"N; 73°9'421"E; Binjor, western Rajasthan, India) provide insights into the Harappan agriculture between ~ 2900 to ~ 1800 BCE. While δ13C values were used to retrieve hydrological status, δ15N values were used to gauge agricultural intensification. Isotopic data of grains/seeds were generated representing three Indus phases (i) early phase (~ 2900 − 2600 BCE), (ii) transitional phase (~ 2600 − 2500 BCE) and (iii) mature phase (~ 2500 − 1800 BCE). We find δ13C values of barley grains (winter crop) varied in overlapping ranges for all the three phases − 21.3‰±1.9; −22.9‰±1.6 and − 22.7‰±1.7 respectively (n = 10 for each phase) indicating insignificant changes in hydrology for winter crops. For summer crops cotton also, average δ13C values for transitional phase − 23.7‰±1.8 were not significantly different from those of mature phase − 22.5‰±2.4. δ15Nbarley values also varied in wider ranges, however, intra-phase variability appears to have progressively increased from early (8.0‰±1.7) to transitional phase (7.3‰±2.5) and then mature phase (9.2‰±7.2) indicating a plausible agricultural intensification. We also measured δ13C of host soil organic matter (SOM) and sediment δ15N to assess regional environmental conditions. In contrast to the trends observed for archaeological grains, δ13CSOM values showed a statistically significant enriching trend from early (−23.6‰±1.4) to mature phase (−20.3‰±1.9) hinting a growing aridity in the region. We surmise that Harappan farmers of western Rajasthan region might be managing arable hydrological conditions in their fields through agricultural interventions to continue agriculture practices despite growing aridity in the vicinity.

Published: June 2023

Three ionic liquids (ILs)(1-ethyl-2,3-dimethylimidazolium acetate, [EMMIM][AC]; tributyl-methylammonium acetate, [N4,4,4,1][AC]; and tetraethylammonium acetate, [N2,2,2,2][AC]) were chosen. The vapor-liquid equilibrium (VLE) data of ternary mixtures (acetate + ethanol + IL) were gauged at 101.3KPa. NRTL equation was applied to correlate the data. From NRTL model, for [N2,2,2,2][AC], [EMMIM][AC] and [N4,4,4,1][AC], minimum mole fractions for completely eliminating azeotrope are 0.015, 0.020 and 0.022, respectively. From the average relative volatility and σ-profiles, it can be obtained that the separation ability order is [EMMIM][AC] > [N2,2,2,2][AC] > [N4,4,4,1][AC].

Authors: Alrebdi H.I. , Alsaif Norah , Suraj Sanam , Zotos Euaggelos E.
Published: June 2023

The circular version of the planar restricted 4-body problem is considered. We assume that the two peripheral bodies have not spherical shape but they are either prolate or oblate. The dynamical properties of the points of equilibrium of the system are investigated using several types of numerical methods and techniques. In particular, we calculate not only the coordinates of the positions of the libration points but also their linear stability and dynamical types. Our main objective is to reveal the influence of the mass parameter of the system along with the shape parameter on the equilibrium dynamics. Our analysis indicates that in the case where the peripheral bodies are prolate in shape the equilibrium dynamics of the system is more interesting and complex with respect to the case where the two peripheral bodies have oblate shapes.
Governance and Economic Growth in Afghanistan during the Era of US presence
Authors: GHAFOORI Noorulhaq , Meng Chang
Published: June 2023

Over the course of its 20-year occupation, was the USA successful in establishing a democratic state in Afghanistan that could improve the quality of governance and boost economic growth? The 20-year USA presence in Afghanistan is examined in this paper in terms of how governance affected economic growth. Along with governance indicators, the effects of foreign aid and the labor force as control variables have also been examined on economic growth. To evaluate the equilibrium between research variables, the ARDL-ECM model has been utilized. The result demonstrates that, in the era of US presence, none of the six world governance indicators over the long term have had a significantly positive impact on economic growth. In the long run, the control of corruption has a negative impact, and in the short run, effective government significantly has a positive impact on economic growth during the investigation period. According to our findings, governance indicators have a much smaller impact on economic growth than population size and foreign aid in both short- and long-run equilibrium. Overall, there was a substantial reliance on human resources and international assistance for economic expansion in the era of democracy. The evidence shows that the association between economic growth and governance was found to be very poor, and the administration in Afghanistan had not been able to stimulate economic growth throughout the US presence.
JEL classification: H1, O100
Many bounded versions of undecidable problems are NP-hard
Authors: Klingler Andreas , van der Eyden Mirte , Stengele Sebastian , Reinhart Tobias , de las Cuevas Gemma
Published: June 2023

Several physically inspired problems have been proven undecidable; examples are the spectral gap problem and the membership problem for quantum correlations. Most of these results rely on reductions from a handful of undecidable problems, such as the halting problem, the tiling problem, the Post correspondence problem or the matrix mortality problem. All these problems have a common property: they have an NP-hard bounded version. This work establishes a relation between undecidable unbounded problems and their bounded NP-hard versions. Specifically, we show that NP-hardness of a bounded version follows easily from the reduction of the unbounded problems. This leads to new and simpler proofs of the NP-hardness of bounded version of the Post correspondence problem, the matrix mortality problem, the positivity of matrix product operators, the reachability problem, the tiling problem, and the ground state energy problem. This work sheds light on the intractability of problems in theoretical physics and on the computational consequences of bounding a parameter.
Exploring unsupervised top tagging using Bayesian inference
Authors: Alvarez Ezequiel , Szewc Manuel , Szynkman Alejandro , Tanco Santiago , Tarutina Tatiana
Published: June 2023

Recognizing hadronically decaying top-quark jets in a sample of jets, or even its total fraction in the sample, is an important step in many LHC searches for Standard Model and Beyond Standard Model physics as well. Although there exists outstanding top-tagger algorithms, their construction and their expected performance rely on Montecarlo simulations, which may induce potential biases. For these reasons we develop two simple unsupervised top-tagger algorithms based on performing Bayesian inference on a mixture model. In one of them we use as the observed variable a new geometrically-based observable \tilde{A}_{3}Ã3, and in the other we consider the more traditional \tau_{3}/\tau_{2}τ3/τ2NN-subjettiness ratio, which yields a better performance. As expected, we find that the unsupervised tagger performance is below existing supervised taggers, reaching expected Area Under Curve AUC \sim 0.80-0.81∼0.80−0.81 and accuracies of about 69% -− 75% in a full range of sample purity. However, these performances are more robust to possible biases in the Montecarlo that their supervised counterparts. Our findings are a step towards exploring and considering simpler and unbiased taggers.
Consumer sentiment toward international activist advertising
Authors: Livas Christos , Theofanidis Faidon , Karali Nansy
Published: June 2023

Companies have been increasingly conveying activist advertising messages to international audiences in response to persisting social ills and unsustainable business practices. Given the ambiguity surrounding the effects of international advertising, this study aims to compare the response of local consumers to a multinational brand’s standardized activist advertising strategy with creative executions adapted to the national contexts of Greece and the USA. The selected brand originates from the USA. The paper used a systematic qualitative approach and sentiment analysis using Microsoft Excel and Azure Machine Learning add-in. Analysis conducted on 1,051 user comments in January 2023 regarding two publicly accessible social media posts of a multinational haircare brand showed both similarities and differences in consumer responses. 662 comments were in English and 389 comments were in Greek. The study’s dataset was anonymized entirely and de-identified. The results indicate that consumer sentiment was largely negative in both countries. Although the relative share of negative comments was significantly higher in the USA (96.7%) than in Greece (59.4%), both groups of consumers placed their emphasis on the same themes (e.g., children and products). Therefore, they have perceived the main message similarly, irrespective of the execution differences. Overall, the findings can be attributed to strategic and tactical issues of the activist advertising campaign, as well as to sociocultural particularities of the national context. In the case of international advertising, attempts to incorporate the brand’s stance on a controversial sociopolitical issue into its advertising strategy pose significant risks to business organizations.

La Colección de Papeles Varios (P.V.) del Archivo Histórico de la Universidad de Salamanca (A.U.S.A.) es una colección documental, esto es, un conjunto de documentos reunidos según criterios no objetivos, y que por lo tanto, no  conservan una estructura orgánica ni responden al  principio de procedencia archivístico, y que dado su  interesante material, inédito en gran medida, merece ser consultada por investigadores no sólo vinculados a la historia universitaria, sino también por estudiosos de otras especialidades para los siglos XVI-XVIII. En esta ocasión, nos centraremos en dar a conocer los documentos relacionados con la sátira política. Esta forma documental se caracteriza por la crítica, la cualidad aleccionadora y el humor, convirtiéndose en un extraordinario instrumento de comunicación. Las invectivas al estamento eclesiástico, las críticas a la política u otras cuestiones anecdóticas aparecen reﬂejados en nuestros documentos. Finalmente  presentamos el anexo de los mismos.
Signal enhancement in wireless sensor networks based on adaptive filters
Authors: Tang Jun
Published: June 2023

Wireless sensor networks are widely used in communication, medical treatment, radar and detection. With the vigorous development of computer science and intelligent technology, wireless sensor networks are also constantly improving in the development. Sensor networks are prone to noise interference when input signals, which will affect the estimation accuracy of the network. In order to enhance the signal of sensor network and improve its accuracy, a distributed filtering algorithm based on fusion adaptive weighting is proposed. Before building the model, the experiment first studied the three traditional adaptive filtering algorithms, LMS, RLS and AP, as the basis for building the experimental model. Then, combined with the distributed characteristics of the sensor network, the attributes of the nodes and their influence in the network were considered in the experiment, and the importance and support of the nodes were linearly weighted to obtain the estimated certainty of each sensor node to the target. Finally, a fusion adaptive weighted distributed filtering algorithm is constructed in the experiment. The simulation experiment verifies that the constructed model can reduce the noise interference to a certain extent, which is conducive to the enhancement of its network signal, and its error estimation accuracy is also improved.

The pandemic caused by the spread of COVID-19 has unleashed a health, economic, social and humanitarian crisis worldwide. The strict measures implemented to control this global crisis have threatened adolescents’ coping mechanisms and social support, putting their mental health at risk. This study aims to determine the changes that have occurred in psychological functioning and health during the pandemic lockdown, as well as potential risk and protective factors for youth mental health. Participants were 1637 Chilean adolescents (85.83% female), aged 14-18 years (Mage = 16.40; SD = 1.28), who completed an ad hoc questionnaire and the Depression, Anxiety and Stress Scale (DASS-21). A descriptive and cross-sectional study design was used, multiple logistic regression analyses were conducted. Most adolescents reported severe levels of depression and anxiety with girls being more at risk than boys. Many of them reported a change in social and personal habits. Results further indicate that socio-demographic and COVID-19 related variables have a significant impact on adolescents’ emotional symptoms. Risk factors such as looking for information about the coronavirus, experiencing a recent stressful life event, reporting pre-pandemic mental health problems were significantly related to higher levels of emotional symptoms. Eating a healthy diet was associated with fewer emotional symptoms, while spending more time playing video games was related to more anxiety. Being in a romantic relationship, satisfying social and family relationships acted as protective factors against mental health problems. Further research is necessary to detect risk and protective factors that influence adolescent’s mental health during the COVID-19 pandemic.
Uso de vapeadores como factor de riesgo de injuria pulmonar aguda
Authors: Tamayo López Samuel
Published: June 2023

Introducción: los cigarrillos electrónicos se comercializaron originalmente como una alternativa más segura a los cigarrillos combustibles tradicionales, aunque todavía exponen a los usuarios a toxinas y carcinógenos conocidos. Si bien hay pocos datos disponibles sobre los efectos a largo plazo del uso de cigarrillos electrónicos, miles de usuarios se han enfermado gravemente en una epidemia de lesión pulmonar aguda asociada al uso vapeadores y cigarrillos electrónicos en los Estados Unidos desde marzo de 2019. Se destaca la heterogeneidad de los componentes del líquido de los vapeadores y arroja dudas sobre la seguridad a largo plazo del uso de estos dispositivos. Objetivo: describir el daño y patología que surge a partir de la exposición de los dispositivos electrónicos de liberación de nicotina. Materiales y métodos: revisión de la literatura acerca del daño causado por la exposición y el uso de los dispositivos electrónicos de liberación de nicotina como los vapeadores y cigarrillos electrónicos. Resultados: la injuria pulmonar aguda asociada al uso de vapeadores y cigarrillos electrónicos es una enfermedad respiratoria aguda que puede ser grave y potencialmente mortal; en la serie más grande de 98 pacientes con injuria pulmonar aguda asociada al uso de vapeadores o cigarrillos electrónicos, el 76% de pacientes requirió oxígeno suplementario, 22% requirió ventilación no invasiva y 26% requirió intubación y ventilación mecánica. Hasta el 18 de febrero de 2021, más de 2800 pacientes habían sido hospitalizados por injuria pulmonar aguda asociada al uso de vapeadores en los Estados Unidos y, entre ellos, 68 habían muerto. Conclusiones: un factor de riesgo clave para la injuria pulmonar es el uso de vapeadores o cigarrillos electrónicos. Se desconoce la patogenia exacta, aunque algunos autores sugieren mecanismo inflamatorio y reactividad pulmonar, tampoco se ha descrito un tratamiento óptimo; lo único que resultó generar un avance creciente hacia la mejoría fue el cesar la exposición a las sustancias que componen los líquidos electrónicos.

Huff and Hertel (2001) derive a welfare decomposition for the equivalent variation in the GTAP model. The derivation appears to be very specific to GTAP. Nevertheless, it contains nearly all the ingredients required for performing welfare decomposition for any CGE model. In this paper, the approach of Huff and Hertel (2001) is generalised to derive a welfare decomposition that can be applied to most, if not all, CGE models. General production and utility functions are accommodated, as are foreign income flows. A brief guide to coding the proposed welfare decomposition in GEMPACK is also provided. The decomposition is applied to decomposing the equivalent variation in GTAP.

Podobnie jak błąd może zdeterminować wolę do braku akceptacji małżeństwa zgodnego z nauką Kościoła, sprawiając wadę konsensu, tak również można bezpośrednio wykluczyć wierność małżeńską pozytywnym aktem woli. Samo zjawisko błędu wchodzi w skład zjawiska symulacji, gdyż w obu przypadkach mamy do czynienia z niezgodnością między wolą a jej zewnętrzną formą wyrazu. Nie oznacza to jednak, iż błąd determinujący wolę nie odróżnia się od symulacji. W przypadku bowiem symulacji następuje pozytywne wykluczenie dobra wierności, w przypadku błędu owo wykluczenie jest nieświadome, czyli bez udziału pozytywnego aktu woli kontrahenta. W tym przypadku ów pozytywny akt woli byłby skierowany przeciwko rzeczywistości, której się nie zna.

The present study examined the effect of person-job fit and job crafting on contract employees’ turnover intention. The participants were 135 contract employees of state-owned (BUMN) and private enterprises (BUMS) in Palangkaraya Raya city. They recruited using the quota sampling technique. Three scales were deployed, namely the person-job fit scale, job crafting scales, and turnover intention scales. The collected data were analyzed using multiple linear regression. The result indicating that person-job fit and job crafting affect the employee’s turnover intention. In other words, contract employees with adequate job fit levels and good crafting exhibited low turnover intention. The turnover intention was affected by person-job fit and job crafting. When an employee has the qualifications corresponding to his job position and gets the opportunity to develop his potential the chances of turnover intention are small.

This research was conducted to explore the source of anxiety and coping strategy of youth during the COVID-19 pandemic in Indonesia. A qualitative survey was conducted online with 365 young people aged 15-23 year. Six themes arise in this study that show sources of anxiety of young people, namely: a) fear of being infected with the COVID-19, b) uncertainty about the future, c) social relation problems, d) academic-related anxiety, e) family economic problems, f) exposure to information on cases of COVID-19 infection. We also found eight coping strategies to deal with anxiety, namely religious coping, active coping, making meaning, seeking emotional support, optimism, avoidance, emotional regulation, and exercises. The findings implied that young people develop religiosity and in combination with other coping strategies to endure the unprecedented outbreak of COVID-19. This finding implies that psychological interventions should address religious coping to help young people to cope with various sources of anxiety during stressful life events such as the COVID-19 pandemic.

Los picudos (Coleoptera: Curculionidae) son una de las principales plagas en los sistemas de producción citrícola debido a su distribución y forma de alimentación. El objetivo del presente trabajo fue identificar morfológicamente las especies de picudos asociados al cultivo de limón persa (Citrus latifolia Tanaka) en la zona citrícola del municipio de Huimanguillo, Tabasco, México. Las capturas de picudos se realizaron de manera directa en la copa de los árboles, de septiembre de 2019 a febrero de 2021, para un total de 17 muestreos en tres plantaciones de limón persa, dos con manejo convencional y una con manejo orgánico, cada una con parcelas útiles de dos hectáreas (624 plantas). Se colectaron 1,039 picudos correspondientes a cuatro morfoespecies, de las cuales 240 se identificaron morfológicamente como Epicaerus sp. (1), 355 como Epicaerus sp. (2), 112 como Exophthalmus opulentus y 332 como Cleistolophus subfasciatus.

The paper presents the results of experimental study of the micro-explosive fragmentation of two-liquid drops during heating in a high-temperature medium. The characteristics of secondary fragments during micro-explosive fragmentation of single droplets based on tall oil were studied. With micro-explosive fragmentation of droplets based on crude tall oil, it is possible to increase the evaporation surface area by more than 70 times. It has been established that during the secondary grinding of drops based on crude tall oil due to micro-explosive effects, it is possible to obtain 2–3 times more secondary fragments than when fragmenting drops based on kerosene and filtered tall oil under identical heating conditions.
Consumo óptimo en el retiro con diferentes leyes de mortalidad
Authors: Palafox-Roca Alfredo Omar
Published: June 2023

Objetivo: Este trabajo estudia las trayectorias óptimas de consumo de personas en edad de jubilación que no pretenden heredar. Metodología: Se propone un modelo donde el número de años por vivir de un individuo jubilado es una variable aleatoria. Resultados: Se obtienen soluciones cerradas cuando el individuo depende de una sola fuente de recursos y cuenta o no con una cobertura por longevidad. Recomendaciones: El análisis aquí expuesto puede ayudar al diseño de mejores planes para el retiro. Limitaciones e implicaciones: Este estudio no considera fuerzas de mortalidad con muchos parámetros, los cuales capturan una mayor cantidad de causas de muerte pero que complican obtener soluciones cerradas. Originalidad: El trabajo utiliza una función de utilidad CRRA y considera diferentes fuerzas de mortalidad, estas se caracterizan por contar con un menor número de parámetros para determinar los planes óptimos de consumo. Conclusiones: las soluciones del caso II permiten mejorar los productos ofrecidos por las aseguradoras en beneficio de los asegurados, de la misma manera los gobiernos pueden buscar incidir en estos parámetros para incrementar el bienestar de los pensionados.

Authors: GÖKÇEOĞLU Ulaş , DEĞER Zeynep
Published: June 2023

Bu çalışmada, TBDY 2018’e göre yüksek binaların performansa dayalı tasarım esasları incelenmiş ve örnek bir uygulamayla detaylı bir şekilde irdelenmiştir. Örnek uygulama için İstanbul’da yer alan ve yüksek bina sınıfına giren 26 katlı bir binanın tasarımı ele alınmıştır. Bina, konut ve işyeri amacıyla tasarlanmış olup, taşıyıcı sistemi yoğunlukla betonarme perdelerden oluşmaktadır. Binanın tasarımı (I) ön tasarım, (II) iyileştirme aşaması ve (III) iyileştirilmiş son tasarım olmak üzere üç aşamada tamamlanmış, performans hedefleri TBDY 2018’e uygun olarak belirlenmiştir. Binanın ön tasarımı tasarım depremi altında gerçekleştirilmiş, servis depremi seviyesinde gerekli iyileştirilmeler yapılmış ve maksimum deprem seviyesinde binanın davranışı kontrol edilerek tasarım sonlandırılmıştır. Doğrusal hesap yöntemiyle ve dayanıma göre tasarım felsefesiyle gerçekleştirilen ilk iki tasarım aşaması ETABS programında, zaman tanım alanında doğrusal olmayan analizler içeren ve şekildeğiştirmeye göre tasarım felsefesiyle yapılan üçüncü tasarım aşaması ise Perform3D programında tamamlanmıştır. Binada mimari sebeplerle asimetrik yerleştirilen bodrum perdeleri, binanın tasarım yönteminin belirlenmesinde önemli bir rol oynamış, ayrıca binanın burulma davranışını belirgin şekilde olumsuz etkilemiştir. Taşıyıcı sistemin burulma etkilerini azaltacak şekilde planlanması çalışmanın belirleyici unsurlarından biri olmuştur. Bu çalışmada bir vaka çalışması aracılığıyla özetlenen tasarım adımlarının ve analiz modellerinin oluşturulma esaslarının TBDY 2018’e göre yüksek bina tasarımı konusunda örnek teşkil ederek literatüre katkı sağlayacağı düşünülmektedir.
AUTOMATIC BELT CARDIOPULMONARY RECISUTATION (CPR) DEVICE AND TEST SYSTEM DESIGN
Authors: KAVSAOĞLU Ahmet Reşit , TAMOKUR Mehmet Ali
Published: June 2023

The test system was created by adding flex and force sensors to this manikin to evaluate the results of heart massage applied on an artificial adult manikin, which has a spring that can give the chest stiffness of an adult human. This test system monitors and analyzes cardiopulmonary resuscitation (CPR) applications performed by the automated CPR device or manually by the person. The signals received from the sensor are transferred to the computer via the serial port with the Arduino Uno card and displayed in real-time in MATLAB graphical user interface (GUI). This GUI, designed with Matlab 2021a software, analyzes the sensor signals resulting from CPR. It gives a graph of the repeats of compression per minute, the depth of each compression, and the compressions rate variable performed by the user or the automatic CPR device during the CPR application. This created test system can evaluate the accuracy of both the automatic CPR device performed in this study and the manual CPR application. The test system designed in this respect can be used in the training and evaluation of cardiac massage applications, which is included in the first aid courses in secondary education, associate degree, undergraduate, and vocational education courses.
