Published: July 2023

Non-variceal upper gastrointestinal bleeding (NVUGIB) is a common gastroenterological emergency associated with significant morbidity and mortality. Gastroenterologists and other involved clinicians are generally assisted by international guidelines in its management. However, NVUGIB due to peptic ulcer disease only is mainly addressed by current guidelines, with upper gastrointestinal endoscopy being recommended as the gold standard modality for both diagnosis and treatment. Conversely, the management of rare and extraordinary rare causes of NVUGIB is not covered by current guidelines. Given they are frequently life-threatening conditions, all the involved clinicians, that is emergency physicians, diagnostic and interventional radiologists, surgeons, in addition obviously to gastroenterologists, should be aware of and familiar with their management. Indeed, they typically require a prompt diagnosis and treatment, engaging a dedicated, patient-tailored, multidisciplinary team approach. The aim of our review was to extensively summarize the current evidence with regard to the management of rare and extraordinary rare causes of NVUGIB.

The purpose of this study was to investigate the relationship between distributive justice and the psychological well-being of teachers in the Archdiocese of Bamenda North West Region of Cameroon. The main research question for the study was to find out the effect of distributive justice on the psychological well-being of teachers in the Archdiocese of Bamenda, North West Region of Cameroon. The study employed a cross sectional survey research design. The sample for the study comprised of 270 male and female teachers working in Catholic nursery, primary and secondary schools within the Mankon and Bambui Deaneries of the Archdiocese of Bamenda. Data was analysed using descrpive and inferential statistics. Quantitative data were analyzed using the linear regression technique. Findings revealed that 65% of teachers’ responses indicated dissatisfaction with distributive justice in the Catholic Education Agency of the Archdiocese of Bamenda and also that there was no relationship between distributive justice and the psychological well-being of teachers and thus no significant effect of distributive justice on the psychological well-being of teachers of the Archdiocese of Bamenda. Based on the findings, the study recommended that the government should effectively follow-up, monitor and audit the channels of paying subvention funds to beneficiary private sector teachers to ensure that the money reaches the intended beneficiaries uncompromised. The study further recommended that private sector education employers should uphold honesty, accountability and transparency in the management of subventions and payment of salaries to teachers and that they allow private sector education teachers to exercise their right to form trade union to defend their labour interests.
Influence of conductive carbon content in hydrogel-based composite on morphological and electrical properties for electrochemical energy conversion
Authors: Pawłowska Sylwia , Cysewska Karolina , Ziai Yasamin , Karczewski Jakub , Jasiński Piotr , Molin Sebastian
Published: July 2023

In this work, a strategy for the one-stage synthesis of polymer composites based on PNIPAAm hydrogel was presented. Both conductive particles in the form of conductive carbon black (cCB) and MnCo2O4 (MCO) spinel particles were suspended in the three-dimensional structure of the hydrogel. The MCO particles in the resulting hydrogel composite acted as an electrocatalyst in the OER process. Morphological studies confirmed that the added particles were incorporated and, in the case of a higher concentration of cCB particles, also bound to the surface of the structure of the hydrogel matrix. The produced composite materials were tested in terms of their electrical properties, showing that an increase in the concentration of conductive particles in the hydrogel structure translates into a lowering of the impedance modulus and an increase in the double-layer capacitance of the electrode. This, in turn, resulted in a higher catalytic activity of the electrode in the OER reaction. The use of a hydrogel as a matrix to suspend the catalyst particles, and thus increase their availability through the electrolyte, seems to be an interesting and promising application approach.

The internal audit function focuses on detecting tampering that may occur in government units and enterprises, as well as identifying weaknesses and gaps that the employees of those government units and enterprises suffer from, and then addressing them by to give a neutral technical opinion. This control function of internal audit will increase its effectiveness in the case of construction. The system of tight internal control for the purpose of improving the efficiency of the outputs of the government accounting system. One of the most important results of the research was the lack of application of local and international internal auditing standards and the weakness of the internal control systems in the centrally funded government units, which contributes to the weakness of the efficiency of the outputs of the auditing agencies and a material shortage of internal control, which in turn will be reflected in the weakness of the outputs of the government accounting system. The researcher reached a set of recommendations, the most important of which is the need to implement local and international internal auditing standards in government units funded centrally in order to raise the efficiency of internal auditing agencies, develop and improve the internal control system, and develop its human cadres, which contributes positively to raising the efficiency of control work in these government units.
Policy and the Acquisition of the Second Language in ArabicSpeakers Countries; Iraq And Saudi Arabia as Examples
Authors: Hussien Suad Qahtan
Published: July 2023

Acquiring English as a second language becomes essential for many reasons. Basically, because English is a universal language, moreover, the universe witnesses globalization which turns the whole universe into a small village because of the internet and the rapid expansion of technology, economics, tourism, and the like. However, the mother tongue, to a certain extent, refrains from the process of acquiring a foreign or second language because of several problems. One of these problems that play the controlling role is the policy since it determines and leads the citizens in any given society. In this paper, Iraq and Saudi Arabia, as two Gulf Arab States, have been examined as examples to show how policy plays the dominant role in enhancing the English language in their countries.

Published: July 2023

In today's world of advancements, nearly 84% of people face neck and back pain at some point in their lives, of which 90% is attributed to bad posture. This leads to cervical and lumbar spondylosis, kyphoscoliosis and paraspinal muscle spasm. Poor posture can also lead to more pain along with the degradation of the tissues surrounding our joints. To tackle this health issue, we have developed a novel solution in the form of an AI-enabled smart wearable device that enables one to correct their posture at any time of the day by alerting them about their incorrect posture through haptic vibrations. "ERGON" uses flex sensors, a Bluetooth HC-O5 module, an Arduino Nano and a vibrator module to create a life style improvement habit making device. The device will be inserted into a cotton sleeve which will be strapped onto the body with the sensor on the spinal region. "ERGON" is affordable, almost one-third of the cost of similar devices sold in market, light weight and small that can be worn comfortably under clothes. It is worthwhile to mention that ERGON has undergone multiple rounds of prototype refinement where the initial version using infrared sensors to the improved current version of ERGON which uses flex sensors, which changes its readings on being bent. The market viability and customer acceptance of the product was corroborated through need identification surveys where 71% of people replied that they face back and neck problems in their day-to-day life, and that this product will be highly beneficial for them. Additionally, our application allows the user to go through weekly posture progress reports, notifications and free training links and videos helping them gain good postural integrity.

Published: July 2023

The study investigated socioeconomic characteristics, aquacultural practices and constraints among smallholder fish farmers in the study location of Bo City, Southern Sierra Leone. The present study employed a survey research design. The smallholder farmers who were growing food for themselves, for sale, and for consumption by others as well as those who were primarily growing it for the market were each given 40 questionnaires in total. The results revealed that most of the respondents were male (90.0%), married (60.0%), lacked training in fish farming (57.5%) and the household income of most (60.0%) ranged from NLe600-NLe1,000. The farmers mostly opined low fish farming experience (70.0%), Semi-intensive fish farming (67.5%), low aquaculture development (57.5%), predominantly seasonal fish pond irrigation (77.5%). All of the respondents’ view fish farming as an economically viable enterprise as well as a profitable (87.5%) entity. The mean rank of constraints was significantly (p ≤ 0.006) differed among fish farmers. The key fish farming constraints included culturing fish, fish feed in culturing fish, less interest, fewer fish farmers, high inputs, high cost of fish pond construction and intensive capital investment that could be exploited for improved productivity. The outcomes of these recent studies imply that fish farmers should receive training and funding for their operations to improve their competitiveness in their smallholder fish businesses as well as in the local and international aquaculture industries. Also, the governments and other practitioner authorities ought to implement policies and initiatives that would support fish farming activities, further research development in aquaculture, the development of the nation, and the fish farmers themselves.

Authors: KARAAĞAÇ Oğuz Han , BİYİK İsmail
Published: July 2023

Giriş ve Amaç: Bu çalışmamızda, düşük tehdidi ile başvuran hastaların hangilerinin düşükle sonuçlanacağını öngörebilmek için tam kan sayımı parametrelerinin araştırılması planlanmıştır.

Gereç ve Yöntem: Bu retrospektif kohort çalışmasına abortus imminens tanısı olan 205 kadın hasta dahil edilmiştir. Birinci grupta abortus imminens tanısı olan ve düşük yapan hastalar, ikinci grupta ise abortus imminens tanısı olan ve gebeliği devam eden hastalar olmak üzere hastalar gebelik sonucuna göre iki gruba ayrılmıştır. Hastaların hastaneye başvuruları sırasında bakılan tam kan sayımı parametrelerinden hemoglobin (Hgb), hematokrit (Hct), trombosit (Plt), beyaz kan hücreleri(WBC), nötrofil, lenfosit, ortalama trombosit hacmi (MPV), trombosit dağılım genişliği (PDW) değerleri kaydedilmiş ve platelet-lenfosit oranı (PLR), nötrofil-lenfosit oranı (NLR), monosit-lenfosit oranı (MLR), sistemik inflamatuar index (SII) gibi değerler hesaplanıp kaydedilmiştir.

Bulgular: Bu çalışmada, gebelik sonucu düşükle sonuçlanan grubun yaşı, 30 (27-36), gebelik sonucu doğum ile sonuçlanan gruba göre, 29 (25-33), anlamlı olarak daha yüksek olduğu saptanmıştır (p=0.021). Abortus grubunun parite sayısı, doğumla sonuçlananlara göre yüksek bulunmuştur ( 1(0-2) vs 1(0-1); p=0,017). Doğum grubunda yaşayan çocuk sayısı abortus grubundan yüksek bulunmuştur (1(1-2) vs 1(0-2); (p=0.021). Diğer demografik veriler açısından gruplar arasında anlamlı fark bulunamamıştır (p>0.05). abortus imminens tanısı olanlarda, gebelik sonuçlarını öngörmede tam kan sayımı parametrelerinde istatistiksel anlamlı bir fark saptanmamıştır (p>0.05).

Sonuç: Düşük tehdidi ile başvuran hastalarda tam kan sayımı parametrelerini araştırdığımız bu çalışmada, gebelik sonucu düşük ile sonuçlanan ve gebelik sonucu doğumla sonuçlanan gruplar arasında tam kan sayımı parametreleri açısından istatistiki olarak anlamlı fark bulunamamıştır. Sonuç olarak düşük gelişecek hastaları öngörmede, tam kan sayımı parametrelerinin klinik kullanımı mümkün görünmemektedir.

Aims: To evaluate the placental pathologies of pregnant women diagnosed with COVID-19 according to disease severity.

Materials and method: This retrospective study was conducted at a tertiary center between April 2020 and February 2023. The placentas of 125 pregnant women in their third trimester who were positive for SARS-CoV-2 were examined. Placental pathologies were classified according to the modified Amsterdam criteria. According to the disease severity, the patients were divided into two groups: non-severe COVID-19 (n=104) and severe COVID-19 (n=21). Placental pathology results were compared between the two groups.

Results: The rates of maternal vascular malperfusion (MVM) and fetal vascular malperfusion (FVM) were 90.4% and 45.2% in the non-severe COVID-19 group. Whereas it was significantly lower at 71.4% and 19% in the severe COVID-19 group (p=0.018 and p=0.026, respectively). The rate of delayed villous maturation (DVM) was 9.5% in the severe COVID-19 group and 1% in the non-severe COVID-19 group, indicating a statistically significant difference (p=0.019). Inflammatory pathologies and other pathological findings were similar between the two groups. Intensive care unit (ICU) admission, presence of accompanying maternal diseases, and postpartum complications were statistically significantly higher in the severe COVID-19 group (p
Confirming Resonance in Three Transiting Systems
Authors: Quinn Tyler , MacDonald Mariah G.
Published: July 2023

Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics. Here, we perform such a study for five multiplanet systems: Kepler-226, Kepler-254, Kepler-363, Kepler-1542, and K2-32. For each system, we run a suite of N-body simulations that span the full parameter space that is consistent with the constrained orbital and planetary properties. We study the stability of each system and look for resonances based on the libration of the critical resonant angles. We find strong evidence for a two-body resonance in each system; we confirm a 3:2 resonance between Kepler-226c and Kepler-226d, confirm a 3:2 resonance between Kepler-254c and Kepler-254d, and confirm a three-body 1:2:3 resonant chain between the three planets of Kepler-363. We explore the dynamical history of two of these systems and find that these resonances most likely formed without migration. Migration leads to the libration of the three-body resonant angle, but these angles circulate in both Kepler-254 and Kepler-363. Applying our methods to additional near-resonant systems could help us identify which systems are truly resonant or nonresonant and which systems require additional follow-up analysis.

A fundamental property of coronal mass ejections (CMEs) is their radial expansion, which determines the increase in the CME radial size and the decrease in the CME magnetic field strength as the CME propagates. CME radial expansion can be investigated either by using remote observations or by in situ measurements based on multiple spacecraft in radial conjunction. However, there have been only few case studies combining both remote and in situ observations. It is therefore unknown if the radial expansion in the corona estimated remotely is consistent with that estimated locally in the heliosphere. To address this question, we first select 22 CME events between the years 2010 and 2013, which were well observed by coronagraphs and by two or three spacecraft in radial conjunction. We use the graduated cylindrical shell model to estimate the radial size, radial expansion speed, and a measure of the dimensionless expansion parameter of CMEs in the corona. The same parameters and two additional measures of the radial-size increase and magnetic-field-strength decrease with heliocentric distance of CMEs based on in situ measurements are also calculated. For most of the events, the CME radial size estimated by remote observations is inconsistent with the in situ estimates. We further statistically analyze the correlations of these expansion parameters estimated using remote and in situ observations, and discuss the potential reasons for the inconsistencies and their implications for the CME space weather forecasting.
Finite Temperature Description of Fermi Gases with In-medium Effective Mass

Published: July 2023

We investigate Fermi gases at finite temperature for which the in-medium effective mass may not be constant as a function of the density, the temperature, or the chemical potential. We suggest a formalism that separates the terms for which the mass is constant from the terms that explicitly treat the correction due to the in-medium effective mass. We employ the ensemble equivalence in infinite matter to treat these different terms. Our formalism is applied in nuclear matter and we show its goodness by comparing it to an exact treatment based on the numerical calculation of the Fermi integrals.

We present the analysis of the magnetic field (B-field) structure of galaxies measured with far-infrared (FIR) and radio (3 and 6 cm) polarimetric observations. We use the first data release of the Survey of extragALactic magnetiSm with SOFIA of 14 nearby (

). For spiral galaxies, FIR B-fields are 2%–75% more turbulent than the radio B-fields. For starburst galaxies, we find that FIR polarization is a better tracer of the B-fields along the galactic outflows than radio polarization. Our results suggest that the B-fields associated with dense, dusty, turbulent star-forming regions (those traced at FIR) are less ordered than warmer, less dense regions (those traced at radio) of the interstellar medium. The FIR B-fields seem to be more sensitive to the activity of the star-forming regions and molecular clouds within a vertical height of a few hundred parsecs in the disk of spiral galaxies than the radio B-fields.
Particles in Relativistic MHD Jets. I. Role of Jet Dynamics in Particle Acceleration
Authors: Dubey Ravi Pratap , Fendt Christian , Vaidya Bhargav
Published: July 2023

Relativistic jets from (supermassive) black holes are typically observed in nonthermal emission, caused by highly relativistic electrons. Here, we study the interrelation between three-dimensional (special) relativistic magnetohydrodynamics, and particle acceleration in these jets. We inject Lagrangian particles into the jet that are accelerated through diffusive shock acceleration and radiate energy via synchrotron and inverse Compton processes. We investigate the impact of different injection nozzles on the jet dynamics, propagation, and the spectral energy distribution of relativistic particles. We consider three different injection nozzles—injecting steady, variable, and precessing jets. These jets evolve with substantially different dynamics, driving different levels of turbulence and shock structures. The steady jet shows a strong, stationary shock feature, resulting from a head-on collision with an inner back-flow along the jet axis—a jet inside a jet. This shock represents a site for highly efficient particle acceleration for electrons up to a few tens of TeV and should be visible in emission as a jet knot. Overall, we find that the total number of shocks is more essential for particle acceleration than the strength of the shocks. The precessing jet is most efficient in accelerating electrons to high energies reaching even few hundred TeVs, with power-law index ranging from 2.3 to 3.1. We compare different outflow components, such as the jet and the entrained material concerning particle acceleration. For the precessing nozzle, the particle acceleration in the entrained material is as efficient as that in the jet stream. This is due to the higher level of turbulence induced by the precession motion.

Galactic science encompasses a wide range of subjects in the study of the Milky Way and Magellanic Clouds, from young stellar objects to X-ray binaries. Mapping these populations, and exploring transient phenomena within them, are among the primary science goals of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time. While early versions of the survey strategy dedicated relatively few visits to the Galactic Plane region, more recent strategies under consideration envision a higher cadence within selected regions of high scientific interest. The range of galactic science presents a challenge in evaluating which strategies deliver the highest scientific returns. Here we present metrics designed to evaluate Rubin survey strategy simulations, based on the cadence of observations they deliver within regions of interest to different topics in galactic science, using variability categories defined by timescale. We also compare the fractions of exposures obtained in each filter with those recommended for the different science goals. We find that the baseline_v2.x simulations deliver observations of the high-priority regions at sufficiently high cadence to reliably detect variability on timescales >10 days or more. Follow-up observations may be necessary to properly characterize variability, especially transients, on shorter timescales. Combining the regions of interest for all the science cases considered, we identify those areas of the Galactic Plane and Magellanic Clouds of highest priority. We recommend that these refined survey footprints be used in future simulations to explore rolling cadence scenarios, and to optimize the sequence of observations in different bandpasses.

The fractional Hardy-type operators of variable order is shown to be bounded from the grand Herz spaces $ {\dot{K} ^{a(\cdot), u), \theta}_{ p(\cdot)}(\mathbb{R}^n)} $ with variable exponent into the weighted space $ {\dot{K} ^{a(\cdot), u), \theta}_{\rho, q(\cdot)}(\mathbb{R}^n)} $, where $ \rho = (1+|z_1|)^{-\lambda} $ and

Nonhomogeneous nonlinear integral equations on bounded domains
Authors: Yi Xing
Published: July 2023

This paper investigates the existence of positive solutions for a nonhomogeneous nonlinear integral equation of the form

   \begin{document}$ \begin{equation} u^{p-1}(x) = \int_{\Omega} \frac{u(y)}{|x-y|^{n-\alpha}} d y+\int_{\Omega} \frac{f(y)}{|x-y|^{n-\alpha}} d y, \ x \in \bar{\Omega}\nonumber \end{equation} $\end{document}

where $ \frac{2n}{n+\alpha}\leq p < 2, $ $ 1 < \alpha < n $, $ n > 2, $ $ \Omega $ is a bounded domain in $ \mathbb R^{n} $. We show that under suitable assumptions on $ f, $ the integral equation admits a positive solution in $ L^{\frac{2n}{n+\alpha}}\left(\Omega\right) $. Our method combines the Ekeland variational principle, a blow-up argument and a rescaling argument which allows us to overcome the difficulties arising from the lack of Brezis-Lieb lemma in $ L^{\frac{2n}{n+\alpha}}(\Omega) $.
Un silence sans ambiance. Hammershøi, les impressionnistes et le tournant atmosphérique contemporain
Authors: Choplin Hugues
Published: July 2023

Cet article entend problématiser, dans une perspective esthétique, le « tournant atmosphérique » contemporain. À partir d’une confrontation entre la peinture française impressionniste et la peinture du danois Vilhelm Hammershøi (1864-1916), nous distinguons trois concepts, porteurs, pensons-nous, de trois voies esthétiques différentes :  — l’ambiance, adéquate aux impressionnistes et aux philosophies de la situation ou, comme nous le dirons, de l’autour ; — l’atmosphère, engagée par le questionnement de la peinture que déploie une certaine philosophie française du XXe siècle (Deleuze, Merleau-Ponty, Levinas) ;  — enfin, le silence, propre à la peinture d’Hammershøi. Dans quelle mesure ce silence, sans ambiance ni atmosphère, peut-il annoncer un art du commun irréductible au tournant atmosphérique ?
Facteurs sociaux de vulnérabilité face à la violence conjugale et sortie de la violence : analyses détaillées de parcours féminins
Authors: Mullner Pauline , Mazuy Magali
Published: July 2023

Cet article s’intéresse à l’articulation de facteurs sociaux qui permettent l’émergence et surtout le maintien de situations de violences conjugales. Les parcours de vie analysés invitent à lire les violences conjugales au sein d’un continuum de violences de genre. Âge et écart d’âge des partenaires, statut d’activité, parentalité, handicap ou santé dégradée, adversité pendant l’enfance ou l’adolescence, sont autant de dimensions à prendre en compte dans l’analyse des parcours de ces femmes confrontées à la violence d’un conjoint. Cet article met également en évidence l’absence manifeste des institutions dans les parcours de sortie de la violence. C’est par leurs ressources propres (activité, rencontres de figures de soutien, mise en sécurité des enfants), soutenues par des membres de leur entourage et/ou des professionnels de santé que les femmes s’en sortent, non pas grâce à une sanction judiciaire ou sociale des agresseurs.
De la violence familiale à la violence institutionnelle. Le continuum des violences dans l’expérience des jeunes placés en protection de l’enfance
Authors: Lacroix Isabelle , Chaïeb Sarra , Dietrich‑Ragon Pascale , Frechon Isabelle
Published: July 2023

Depuis cinq ans, plusieurs rapports et témoignages d’anciens enfants placés interpellent les pouvoirs publics sur les violences subies par les enfants et jeunes dans des institutions de protection de l’enfance. Pourtant, leur parole peine à être entendue. À partir d’une enquête par questionnaires et entretiens (l’enquête longitudinale sur les conditions de vie et de sortie des jeunes du système de protection de l’enfance, ELAP), cet article s’intéresse au continuum des situations de violences – avant et pendant le placement – auquel ont été confrontés les jeunes rencontrés. Nous verrons que, dans certains cas, les établissements et familles d’accueil participent à produire ou à prolonger les violences auxquelles ils devraient pourtant mettre fin.
