Evolution of Negative Superhumps, Quasiperiodic Oscillations, and Outbursts in the Z Cam-type Dwarf Nova AH Her
Authors: Sun Qi-Bin , Qian Sheng-Bang , Li Min-Yu
Published: September 2023

AH Her is a Z Cam-type dwarf nova with an orbital period of ∼0.258 days. Dwarf nova oscillations and long-period dwarf nova oscillations have been detected, but no quasiperiodic oscillations (QPOs) and negative superhumps (NSHs) have been found. We investigated the association between NSHs, QPOs, and outbursts of AH Her based on Transiting Exoplanet Survey Satellite photometry. We find for the first time NSHs with a period of 0.24497(1) days in AH Her, and trace the variation in the amplitude and period of NSHs with the outburst. The amplitude of the NSHs is the most significant at quiescence, weakening as the outburst rises, becoming undetectable at the top, rebounding and weakening at the plateau, and strengthening again as the outburst declines. The variation in the accretion disk radius can explain the NSH amplitude variation except for the plateau, so we suggest that the relationship between the NSH amplitude and outburst can be used as a window to study the accretion disk instability and the origin of NSHs. In addition, we find periodic variations in the amplitude, maxima, and shape of the NSHs ranging from 2.33(2) to 2.68(5) days, which may be related to the precession of the tilted disk. Finally, we find QPOs at the top of AH Her’s long outburst with ∼2800 s similar to those of HS 2325+8205, suggesting that the presence of QPOs at the top of Z Cam’s long outburst may be a general phenomenon.
Pulsar Timing Array Detections of Supermassive Binary Black Holes: Implications from the Detected Common Process Signal and Beyond
Authors: Chen Yunfeng , Yu Qingjuan , Lu Youjun
Published: September 2023

Pulsar timing arrays (PTAs) are anticipated to detect the stochastic gravitational-wave background (GWB) from supermassive binary black holes (BBHs) as well as the gravitational waves from individual BBHs. Recently, a common process signal was reported by several PTAs. In this paper, we investigate the constraints on the BBH population model(s) by current PTA observations and further study the detections of both the GWB and individual BBHs by current and future PTAs. We find that the massive black hole–host galaxy scaling relation, an important ingredient of the BBH population model, is required to either evolve significantly with redshift or have a normalization ∼0.86–1.1 dex higher than the empirical ones if the GWB is the same as the common process signal. For both cases, the estimated detection probability for individual BBHs is too small for a positive detection by current PTAs. By involving either the constrained scaling relations or those empirical ones into the BBH population models, we estimate that the GWB may be detected with a signal-to-noise ratio ≳3 by the China Five-hundred-meter Aperture Spherical radio Telescope PTA (CPTA) and the Square Kilometre Array PTA (SKAPTA) after ∼2–3 (or ∼6–11) yr observation if it is the same as (or 1 order of magnitude lower than) the common process signal. The detection time of individual BBHs by CPTA and SKAPTA is close to that of the GWB detection. We show that the BBH population model can be strongly constrained by the number and property distributions of BBHs to be detected by future PTAs.

Published: September 2023

A phase-resolved analysis on the X-ray spectrum of ultraluminous X-ray pulsar (ULXP) NGC 300 ULX-1 is performed with data taken with XMM-Newton and NuSTAR on 2016 December 16. In addition to the classical phase-restricting analysis, a method developed in active galactic nuclei studies is newly employed for ULXP. It has revealed that the pulsation cycle of the source can be divided into two intervals in terms of X-ray variability. This suggests the rotating flow consists of at least two representative emission regions. Furthermore, the new method successfully decomposed the spectrum into an independent pair in each interval. One is an unchanging-component spectrum that can be reproduced by a standard disk model with a

km inner radius and a 0.25 ± 0.03 keV peak temperature. The other is the spectrum of the component that coincides with the pulsation. This was explained with a Comptonization of a

keV blackbody and exhibited a harder photon index in the brighter phase interval of two. The results are consistent with a picture that the pulsating emission originates from a funnel-like flow formed within the magnetosphere, and the inner flow exhibiting a harder continuum is observed exclusively when the opening cone points to the observer.
Unveiling the Dynamics of Dense Cores in Cluster-forming Clumps: A 3D Magnetohydrodynamics Simulation Study of Angular Momentum and Magnetic Field Properties
Authors: Kinoshita Shinichi. W. , Nakamura Fumitaka
Published: September 2023

We conducted isothermal magnetohydrodynamics simulations with self-gravity to investigate the properties of dense cores in cluster-forming clumps. Two different setups were explored: a single rotating clump and colliding clumps. We focused on determining the extent to which the rotation and magnetic field of the parental clump are inherited by the formed dense cores. Our statistical analysis revealed that the alignment between the angular momentum of dense cores,

L

core

, and the rotational axis of the clump is influenced by the strength of turbulence and the simulation setup. In single rotating clumps, we found that

L

core

tends to align with the clump’s rotational axis if the initial turbulence is weak. In colliding clumps, however, this alignment does not occur, regardless of the initial turbulence strength. This misalignment in colliding clumps is due to the induced turbulence from the collision and the isotropic gas inflow into dense cores. Our analysis of colliding clumps also revealed that the magnetic field globally bends along the shock-compressed layer, and the mean magnetic field of dense cores,

B

core

, aligns with it. Both in single rotating clumps and colliding clumps, we found that the angle between

B

core

and

L

core

is generally random, regardless of the clump properties. We also analyzed the dynamical states of the formed cores and found a higher proportion of unbound cores in colliding clumps. In addition, the contribution of rotational energy was only approximately 5% of the gravitational energy, regardless of the model parameters for both single and colliding cases.

Purpose: The aim of this research is to analyze the academic literature on online grocery shopping to identify a set of variables to assess by means of a validated survey the shopping habits of the population of Catalonia, starting from COVID-19, in a representative sample of the population in the 2020-2021 pandemic period.Design/methodology/approach: The methodology used for this research is qualitative and quantitative, since a validated survey is carried out with a representative sample of the population of Catalonia and subsequently, using a quantitative methodology, the answers of the questionnaire are analyzed using descriptive statistics to interpret the results and reach conclusions.Findings: More people are planning to shop online in the future because of COVID-19 than not people who have shopped online for the first time during the pandemic. Users who have increased their online grocery shopping during the pandemic also intend to use online grocery shopping in the future. Because of COVID-19, the adoption of online grocery shopping has advanced by a few years. However, it must be taken into account that the consumer still perceives risks, such as the fact that many people want to see fresh products before buying them.Originality/value: The most relevant contribution of this work is related to show how online food shopping is for customers and to value the shopping experience in times of pandemic. Thus, the results are intended to contribute to assess online grocery shopping and to detect the customer's perception of this type of shopping.
DO MULTIFACTOR MODELS CONTRIBUTE TO ESTIMATE THE COST OF EQUITY CAPITAL IN BRAZIL?
Authors: Pani Victor , Leal Ricardo , Roquete Raphael Moses
Published: September 2023

This study investigates the contribution of well-known multifactor asset pricing models to estimate the cost of equity capital of Brazilian listed companies with the Capital Asset Pricing Model (CAPM), the three-factor model of Fama and French (1993), the Carhart (1997) four-factor model and a five-factor model that consists of an additional illiquidity risk factor. The sample are the returns of individual stocks comprising a portfolio of companies in the IBrX 100 stock index from July 2008 to June 2018. Distributions of individual company cost of equity capital estimates obtained with each model were compared among themselves in the full sample period and two sub-periods. The results suggest that adding extra risk factors to the CAPM does not always translate into different cost of equity capital estimates and significantly greater explanatory power. The practical implication is that the CAPM estimates may often be the same as those obtained by means of more complex models with the added bonus of the CAPM's simplicity.

Tracheal or bronchial foreign body aspiration is an important emergency o childhood requiring bronchoscopy under general anesthesia. In this retrospective study, bronchoscopy were performed for foreign body aspiration; anesthesia methods, risks, and postoperative complications were evaluated. Children who underwent bronchoscopy with suspicion of a foreign body in the pediatric surgery operating room between January 2010 and December 2021 were included in the study. Six hundred and sixty four children were evaluated. General anesthesia was applied to all bronchoscopy. Demographic characteristics of the patients, type of foreign body, localization of foreign body, distribution of foreign body according to age groups, complications related to anesthesia and surgical process, length of stay in the postoperative intensive care unit, and duration of hospital stay were evaluated. The patients who aspirated foreign bodies most frequently were children aged 1-3 years (73.6%). During bronchoscopy, organic matter (seeds, hazelnuts, peanuts, chickpeas) was the most frequently removed foreign body in children (559 patients). It was observed that foreign bodies were mostly located in the right main bronchus at a rate of 52.4%, the left main bronchus at 28%. The most common anesthesia-related complications were desaturation in 400 patients, hypercarbia in 200 patients, bronchospasm in 108 patients, and respiratory arrest in 2 patients. Many problems may be encountered in foreign body inhalation, and bronchoscopy of these patients should be performed by an experienced anesthesiologist and surgeon at the right time and in the safest way in terms of anesthesia and surgery.

Infections caused by resistant Gram-negative bacteria are a serious public health problem, with Klebsiella spp. being the most common cause and increasing over the years. There is a striking increase in antibiotic resistance worldwide. The aim of this study was to retrospectively evaluate the characteristics and treatment of bloodstream infections (BSIs) caused by Klebsiella spp. and to identify possible risk factors for extended-spectrum β-lactamase (ESBL) resistance in our hospital between August 2019 and March 2023. Of 250 Klebsiella isolates, 112 (44.8%) were ESBL producers and 138 (55.2%) were ESBL nonproducers. Catheter-related BSIs (CRBSIs) accounted for 49.6% of infections and were more common in the ESBL nonproducer group. Most of the Klebsiella spp. were K. pneumoniae (233/250). Most of the infections were healthcare-associated infections (85.6%). Most patients had an underlying disease, the most common underlying disease in the ESBL-producing group was neurometabolic disease (26.8%), whereas in the ESBL-non-producing group it was malignancy (35.5%). The median age of the ESBL-producing group was 14 months and was younger (p=0.01). Previous antibiotic use in the last 30 days, especially aminoglycosides (p<0.006), β-lactam-β-lactamase inhibitor combinations (p<0.001) and cephalosporins (p<0.001), increased ESBL-resistant infection. Use of β-lactam-β-lactamase inhibitor combinations in the last 30 days increased the risk of ESBL resistance by approximately 7.4 times, and cephalosporins increased the risk by 5 times. In the ESBL-producing group, the median duration of treatment was longer at 14 days (p=0.01), and carbapenems were most commonly used (p<0.001). Thrombocytopenia (p=0.003), elevated C-reactive protein (p<0.001), CRBSI (p=0.009), presence of central venous catheter (p=0.03), urinary catheter (p<0.001), mechanical ventilation (p<0.001), intensive care admission (p=0.005), previous use of carbapenems, aminoglycosides, fluoroquinolones in the last 30 days (p=0.003, p=0.001, p=0.006, respectively) and colistin treatment (p<0.001) increased the risk of mortality. The 28-day mortality rate was 11.6%. Appropriate use of narrow-spectrum antibiotics and reduction of invasive procedures is important in reducing ESBL resistance and BSI-related mortality.
Associated ultrasound findings improve the accuracy of twinkling artifacts in kidney stone diagnosis
Authors: Rojthamrong Rujiluck , Sasiwimonphan Kewalee
Published: September 2023

Background: Twinkling artifact (TA) in color Doppler ultrasound is commonly used as a sign of kidney tract stone detection but the accuracy is limited as compared with unenhanced computed tomography (CT).
Objective: Define the associated ultrasound findings that may improve the accuracy of TA compared with CT for diagnosing kidney stones.
Materials and Methods: Prospective study was conducted on 128 TAs in patients sent for unenhanced CT KUB and performed color Doppler ultrasound on the same day. TA sizes and associated sonographic signs were recorded and analyzed with receiver operating characteristic curves (ROCs). The diagnostic reference was the CT scan.
Results: There was a total of 128 TAs with the size of 3.95 mm (2.7-6 mm). Only 30 TAs showed as kidney stones in CT. The sizes of kidney stones in CT were 5.4 mm (3.4-6.4 mm) which represented a significant difference in TA size (P = 0.002). ROC curve analysis showed that 5 mm would be the optimal size of TA for kidney stone predictions. Other significant signs for improved diagnosis include echoic foci (P = 0.039), posterior shadows (P = 0.001), long TA tails (P = 0.001) and 2nd approach TA (P = 0.001). Then a predictive AT model was created to predict kidney stones, which moderately improved diagnosis accuracy for kidney stones with good agreement.
Conclusion: The combination of TA and other sonographic signs are moderately associated with kidney stone diagnosis including TA size (> 5 mm), posterior acoustic shadow, long TA tail, junctional line location and focal Caliectasis.

Authors: Barbosa Rômulo Soares
Published: September 2023

No Alto Rio Pardo, Norte de Minas Gerais, as comunidades geraizeiras lutam pela transformação das áreas ocupadas com monocultura de eucalipto em territórios reconvertidos com a vegetação do cerrado. Esse processo tem sido denominado de reconversão territorial agroextrativista geraizeira. Trata-se de um processo social que envolve a delimitação, autodemarcação e regularização fundiária, seja por meio da criação de assentamentos agroextrativista, seja como unidades de uso sustentável (Reservas Extrativistas ou Reservas de Desenvolvimento Sustentável). O artigo tem por objetivo analisar as lutas das comunidades geraizeiras pela reconversão territorial e os efeitos sobre a proteção da biodiversidade e as águas. Os procedimentos metodológicos foram: pesquisa bibliográfica, pesquisa documental, elaboração e interpretação de mapas e dados sobre o uso e cobertura do solo. Os resultados indicam que esse processo de reconversão territorial, em curso, tem possibilitado a regeneração de áreas de cerrado degradadas pela monocultura de eucalipto, com efeitos para a recuperação dos corpos hídricos.
Prilog interpretaciji Feuerbachove sumnjive odsutnosti
Authors: Kovačić Darko
Published: September 2023

Ricoeurov koncept „Gospodara sumnje“ temelji se na propoziciji da su Marx, Nietzsche i Freud iznijeli radikalnu interpretaciju ljudske svijesti, povijesti i kulture zalazeći u skrivene motive i latentna značenja koja često izmiču površnom promatranju. Svaki je od njih i na svoj način, primijenio metodologiju koju Ricoeur naziva „hermeneutika sumnjom“, razotkrivajući temeljne strukture, želje i sukobe koji oblikuju općenito ljudsko, a posebno religijsko iskustvo. Njihove su kritike religije ponudile jednu dublju analizu u konačnici razotkrivajući zamršene odnose između društvene strukture (Marx), dinamike moći (Nietzsche) i ideologije (Freud). U ovom radu postavljamo pitanje: zbog čega, prema Ricoeurovom kanonu najpredaniji od svih paraktikanata hermeneutike sumnjom – Ludwig Feuerbach – ne dijeli ovu cijenjenu titulu s ostalima iz Ricoeurove ‘kuće slavnih’?

Published: September 2023

El artículo aborda la responsabilidad médica penal por omisión en situaciones de emergencia de salud, debido a las dudas que aún existen sobre el accionar médico en estas circunstancias y las posibles consecuencias jurídicas por negligencia, impericia e imprudencia. La responsabilidad médica incluye la obligación moral de responder de los propios actos y reparar o indemnizar las consecuencias perjudiciales para terceros. Se identifican las falencias en las normativas ecuatorianas con relación al actuar médico en situaciones de emergencia de salud y se busca aportar a la academia con publicaciones de conocimiento. Se analizan los elementos normativos y fácticos de la responsabilidad médica penal por omisión en situaciones de emergencia de salud en la República de Ecuador, y se busca identificar el marco normativo en la legislación ecuatoriana para superar la inadecuada actuación médica en estas situaciones. El conocimiento de la normativa legal contribuye a superar la responsabilidad médica penal por omisión en situaciones de emergencia en el Ecuador y se menciona y se analiza el art.146 del COIP que es la normativa vigente. El artículo concluye que el objetivo no es criminalizar la práctica médica, ya que no toda muerte es homicidio y no todo proceso judicial implica el encarcelamiento de los involucrados.

Published: September 2023

Los leiomiosarcomas de partes blandas son tumores malignos, que pertenecen a la familia de los sarcomas, constituyendo el 3% de ellos y el 0,04% de todas las neoplasias. Su localización perineal es extremadamente infrecuente y supone dificultades adicionales debido a que en esta región coexisten múltiples limites anatómicos de relevancia en extrema cercanía. Se conocen tasas de recidiva local y de metástasis a distancia de hasta 37% y 62%, respectivamente, por lo que suelen recomendarse abordajes quirúrgicos agresivos, con márgenes amplios, y esquemas de radio y quimioterapia adyuvantes en casos indicados para disminuir estos porcentajes. Se presenta el caso clínico de una mujer de 42 años, con tumoración perineal derecha de 9 años de evolución. Al examen físico lesión móvil no adherida a planos profundos, inicio de dolor ante el aumento de tamaño. Tomografía con contraste endovenoso: tumor de bordes netos, en contacto con pared lateral de recto. Evaluación en comité de tumores. Decisión terapéutica en conjunto con paciente. Tratamiento quirúrgico: resección marginal de tumoración respetando su capsula ad integrum. Anatomía patológica informó leiomiosarcoma de bajo grado. Hasta el momento en seguimiento con buena evolución y sin recidivas. Consideramos que existen alternativas terapéuticas efectivas que consistan en resecciones conservadoras en pacientes seleccionados, de bajo riesgo, con enfermedad localizada, sin que esto signifique resignar tasas de recidiva local ni de sobrevida global. Se necesitan mayor evidencia para demostrar beneficios en cuanto a seguridad.

Published: September 2023

The decline in insurance penetration levels in recent years has been caused by the increasing number of cases of default by life insurance companies, as well as the revocation of business licenses for the insurance broker industry by the Financial Services Authority (OJK), which has resulted in lower interest among the insurance community. This incident became an obstacle for the Association of Indonesian Insurance and Reinsurance Broker Companies (APPARINDO) in carrying out a public relations strategy to build a positive image. This research aims to find out what public relations strategies are used by APPARINDO in building a positive image of the company, and what challenges are faced when implementing the public relations strategy. The method used in this research is a qualitative descriptive method by collecting primary data through interviews from selected informants and secondary data, namely the results of documentation and direct observation. The informants in this research were the Secretariat General of APPARINDO, the Department of Public Relations and Promotion, and the Head of the Secretariat. The results show that APPARINDO implements the public relations mix strategy or PENCILS developed by Thomas L. Harris. The strategies implemented include Publications, Events, News, Community Engagement, Lobbying and Negotiations, and Social Responsibility.
Analysis of the Influence of the Exchange Rate Reform and COVID-19 on the Real Exchange Rate of the Dirham using the BEER Methodology: Case of Morocco

Published: September 2023

Abstract
This article assesses the deviation of Morocco's real effective exchange rate (REER) from its equilibrium, in the wake of the reform of the exchange rate regime and the COVID-19 crisis. Adopting the BEER approach, we examine the evolution of the dirham and discern the internal and external factors influencing its deviation. After elucidating the concept of the equilibrium rate, we detail the methodology employed. Our conclusions reveal the notable impact of the 2018 reform on the REER, marked by the widening of the dirham's fluctuation band, inducing a significant depreciation. In addition, the pandemic has accentuated economic vulnerability, with a recession of -7.2% in 2020. In short, economic equilibrium is essential if Morocco is to face up to the challenges that lie ahead. Competitiveness indicators must be rigorously monitored to guarantee Morocco's competitive position internationally.

Keywords: Real effective exchange rate; Equilibrium rate; BEER approach; Exchange rate regime reform; COVID-19.
The Impact of Boredom in Marriage on Marital Satisfaction
Authors: Muturi Elizabeth
Published: September 2023

Purpose: The aim of the study was to investigate the impact of boredom in marriage on marital satisfaction.

Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low-cost advantage as compared to field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.

Findings: Boredom in marriage can influence the spouses' behaviors, emotions, and cognitions, such as reducing their positive interactions, increasing their negative interactions, lowering their mood, and impairing their judgment. Boredom in marriage can have negative consequences for the individual and relational well-being of the spouses, such as affecting their physical and mental health, undermining their intimacy and commitment, and increasing their risk of infidelity or divorce. Boredom in marriage can be prevented or reduced by enhancing the quality and quantity of communication, sharing new and meaningful experiences, expressing appreciation and affection, seeking professional help if needed, and maintaining a positive attitude and outlook on the relationship.

Unique Contribution to Theory, Practice and Policy: The Arousal Theory, Cognitive Theory and Psychodynamic Theory may be used to anchor future studies on use of marriage institutions. Marital therapists and counselors could incorporate boredom assessment and intervention strategies in their work with couples who report low marital satisfaction. Policymakers and educators could design and implement programs that promote healthy and satisfying marriages in the society.

Las constituciones políticas son reconocidas como documentos estables, aunque adaptables, que deben ajustarse a la dinámica de cada generación para reflejar adecuadamente las bases del Estado, la sociedad y el sistema jurídico. En ese sentido, este artículo de reflexión académica examina el concepto de cambio constitucional, formal e informal, y sus consecuencias, entre estas la perversión, con un enfoque particular en Colombia en donde a pesar de las críticas políticas y jurídicas, la Carta ha experimentado transformaciones significativas para servir a las realidades sociales, sin olvidar la voluntad original del constituyente de 1991. Así, se destaca el papel crucial de la Corte Constitucional colombiana en la protección de la integridad del texto fundamental.
Influence of Gender Stereotype on Performance in Science across Gender among Secondary School Students
Authors: Owino Gor Polycarp , Othuon Lucas
Published: September 2023

The purpose of this study was to establish the influence of gender stereotype on performance in science across gender. Fisher’s formula was used to sample 175 Form IV students from a population of approximately 1,600 in Migori County, Kenya. Questionnaires, Interview Schedules and Focus Group Discussion Guide were used to collect data. Descriptive statistics, correlation and linear regression were used to analyze quantitative data. Qualitative data was organized into themes and interpreted. Boys had a higher level of performance in science (Mean=39.21, SD=13.33) than girls (Mean=30.51, SD=11.83), and the mean difference was statistically significant at α=.05 (t=3.99, p=.00, df=172). Girls displayed a higher level of gender stereotype (Mean=1.67) than boys (Mean=1.66), but this difference was not statistically significant (t=-.187, p=.852). Further, gender stereotype significantly correlated with performance in science for both boys and girls; boys had r=-.272 (p=.002, n=125) and girls had r=-.251 (p=.082, n=49), indicating a stronger relationship for male than female students. In conclusion, the impact of Gender Stereotype on Performance in Science was stronger for female students than male students. We recommend that ways of minimizing gender stereotype among secondary school students should be established because it is negatively associated with performance in science. However, such a move should be more intense for female students than male students.

This research aimed to investigate the effect of service quality on customer loyalty in sports-fitness facilities. The sample of the research consisted of 311 individuals, 165 males and 146 females, who were members of 6 sports – fitness centers in Istanbul and Niğde. In the research, a questionnaire containing 3 parts was used as a data collection tool. In the first part, the items defining the research group were included. In the second part, "Scale of Perceived Service Quality of Sports-Fitness Centers" developed by Uçan (2007) was used. In the third part, the "Customer Loyalty Scale" developed by Zeithaml et al., (1996) and adapted into Turkish by Savaş (2012) was used. SPSS 22 program was used in the analysis of the data, while detailed graphic statistics were used for demographic data, scale scores, and regression analysis was used for relational analysis. When the descriptive statistics results of the research were examined, it was observed that the perceived service quality sub-dimension scores and customer loyalty scale scores were above the mean. Looking at the relational analysis part of the research, it was determined that interaction, output and program quality in sports-fitness facilities had a significant positive effect on customer loyalty. According to these results, it was suggested that sports facilities should give importance to interaction, output and program quality to ensure customer loyalty.

Published: September 2023

Introdução: A dor neuropática é uma patologia de difícil tratamento, caracteriza-se por ser uma dor com etiologia variada, onde ocorre uma lesão ou disfunção do sistema somatossensorial, fazendo com que ocorra uma transmissão e percepção contínua de dor. Nesse contexto, o uso da venlafaxina vem sendo estudado, sendo que o fármaco é utilizado como tratamento de segunda linha para pacientes em que a terapêutica convencional não é indicada. Objetivo: Diante disso, o objetivo geral do trabalho foi demonstrar o uso clínico da venlafaxina no tratamento da dor neuropática. Metodologia: Para isso, utilizou-se como metodologia a revisão de literatura, por meio da coleta de dados em bases como Scielo, Lilacs e Google Acadêmico.  Resultados e Discussão: Os principais resultados obtidos com a pesquisa foram que a venlafaxina comparada com outros fármacos utilizados na terapêutica padronizada, como carbamazepina e pregabalina, apresentou redução da dor, porém em menor escala que a pregabalina e mesmo grau que a carbamazepina, seu mecanismo de ação não está elucidado, porém por ser um antidepressivo inibidor da recaptação de serotonina e noradrenalina acredita-se que o fármaco aumente a concentração destes neurotransmissores na fenda sináptica do neurônio inibitório, reduzindo a transmissão da dor. Conclusão: A venlafaxina demonstrou na maioria dos estudos abordados resultados positivos na diminuição da dor neuropática, mesmo apresentando potencial  analgésico menor em comparação aos fármacos atualmente utilizados é uma opção para casos especiais onde a terapia convencional não é segura, podendo vir a complementar o atual Protocolo Clínicos e Diretrizes Terapêuticas  de Dor Crônica.

In the medical field, advanced techniques such as e-health, intelligent health, and telemedicine apps are being deployed. These approaches use open-source networks to send digital medical images. Patients’ private and sensitive diagnosis is contained in the digital medical image. Then sent the digital medical images are used for diagnosis by the remote center. For this reason, protecting patient privacy and the integrity of medical images is of paramount importance. DNA Digital coding is the most popular form of cryptographic technology, and it is frequently employed to strengthen information security, and the most prevalent constraints of DNA cryptographic schemes feature a high degree of temporal and algor. If DNA is employed appropriately, it can be used to achieve a number of security technologies, including encryption, steganography, signature, and authentication through the use of DNA molecules as information carriers. In this paper, a survey on the digital medical image was done. This survey contains the methods of encryption, and decryption of the image which is based on DNA with all the related methods and makes the comparison between the previous papers and explain which is the best to use.
A Review of Hydraulic Pressure for Water Supply Unites Considering Iraqi Geodetic Reference
Authors: Noora Akeel  , Mustafa Tariq Mustafa  , Muntasir Abdl Hameed  , Corina Boncescu
Published: September 2023

The hydraulic pressure head of the flowing water (between the entrance and exit pipes) in water distribution networks depends on the length and the slope of these pipes, which can represent the head losses for each meter length, where the slope and length of the water supply network pipes are dependent on specified datum ground elevations. This ground elevation may result in a reduction in head losses with hydraulic grade pressure. As a result, the precision of the measured data used to observe ground elevations is critical to decrease the error of these losses and apply an accurate local reference. It's critical to comprehend the implications of using Geographic Information System (GIS) application technology for water distribution network models to evaluate the hydraulic grade head with Iraqi Geodetic Reference. These GIS input data are based on an analysis of the relationship between selected spatial data resolution and the precision of the expected hydraulic head for selected stations with a distribution network. This research aims to review the literature and try to track the conversion of geodetic references and datums to accurately identify the hydraulic pressure for the selected locations of the water supply network. It was found that recent researches tend to use GIS application to create novel methods to reduce head losses and error.

Published: September 2023

The Internet of Things (IoT) also has a huge impact on dramatically lowering healthcare expenses and increasing treatment outcomes. The only ways that patients could communicate with doctors before the Internet of Things were in person, over the phone, or via text. There was no feasible way for healthcare providers to assess patients’ health and offer advice continuously. IoT-enabled technological equipment has made remote monitoring possible in the healthcare industry, opening opportunities to keep patients safe and healthy and empowering medical professionals to provide the best treatment possible. This review provides a comprehensive study of the literature on IoT’s impact (negative or positive) on healthcare delivery and why it is difficult to implement despite its enormous benefits. Search engines (journal publishing databases) like Google Scholar, PubMed, and ScienceDirect were used to find studies on the impact of IoT-based healthcare delivery. Data were extracted from papers found, and the quality of studies that qualified for inclusion and exclusion was assessed and reported. It includes the proposed technologies’ validation as well as their clinical effectiveness. The review found that the lack of government commitment to financing IoT projects is a challenge to its implementation in healthcare delivery since it involves huge capital at the beginning and its maintenance. In addition, some medical professionals are still acquainted with the old-fashioned (manual) ways of delivering their services, hence avoiding the technological approach. Despite the challenges, one noted the positive effect of IoT in healthcare delivery is that doctor-patient interactions have gotten simpler and more effective; it has also raised patient participation and satisfaction. Furthermore, remote patient monitoring shortens hospital stays and avoids readmissions by monitoring patients’ health.

Nowadays, players are required to travel both locally and internationally including short distances of less than 3 hours and long distances. The subsequent travel fatigue may result in several consequences. Football leagues all over the world thrive on a lot of travelling by clubs, supporters, spectators and officials. In Nigeria, travelling from the Northern part of the country to the southern part can take as much as eight hours, while a journey from the North to the South lasts sometimes more than 24 hours due to poor road networks of Nigeria roads and other unforeseen circumstances like robbery, traffic congestion and road traffic accident. The incidence of travelling by road transportation with its consequences have remained unabated over time in Nigeria. The situation can be said to be due to several factors such as dearth of funds, poor road network and inconsistency and non-adherence to calendar/time table over the past five football seasons in Nigeria league. It is therefore recommended that players should have adequate rest before and after each match, The government should improve the road infrastructure and league managers committee should have a working calendar for effective date of kick off and end time of each season.
