Authors: Chidinma Wekhe  , Vivian Ndidi Akagbue
Published: March 2024

Background: Intravenous urography (IVU) is a contrast based radiological procedure for the investigation and imaging of the urinary system. It was the gold standard, not until the last two decades when CTU (computed tomography urography) took over. The latter is better because of its improved accuracy in the diagnosis of urinary tract pathologies. Flank pain is a sensation of discomfort or distress in the part of the body below the rib and above the ilium. The possible organs in the flank to be affected include kidney and ureter. Aim This study is aimed at finding out the IVU findings in patients presenting with flank pain in a tertiary hospital in the southern part of Nigeria. Study design and settings: A retrospective study was conducted in the Radiology Department of Rivers State University Teaching Hospital (RSUTH) from 1st February 2021 to 10th February 2023. Data Analysis: Data was analyzed using SPSS 20.1 version. The level of statistical significance was set at p<0.05. Results: A total of 100 data was analyzed. Patients between the age of 5 years and 76 years with a mean age of 39.72 + 14.33 years was used for this study. Majority of the age group was greater than 41years of age with an equal male to female distribution. That is the ratio of female to male in this study is 1:1. The study shows that more patients had abnormal IVU patterns than normal. More females had normal IVU patterns while abnormal IVU patterns were more common in males. The study also shows that the ureters were more affected than the kidneys because we had more abnormal IVU pattern in the ureter than the kidney. Conclusion: The age group with the highest abnormal IVU pattern is the greater than 41years group, probably because they were more in number in the study population and again may be, we can say the frequency of diseases increases with increasing age.

Published: March 2024

Obwohl das Empfinden sexueller Bedürfnisse in Zeiten der Trauer nichts Ungewöhnliches ist, wird es häufig tabuisiert. Dadurch empfinden Trauernde Scham und Schuld und stellen ihr Fühlen und Handeln infrage. Es bedarf eines Umdenkens, damit trauernde Menschen – auch mit ihren sexuellen Bedürfnissen – akzeptiert werden. Die Autorinnen beleuchten die individuelle Bedeutung von Sexualität und Körperlichkeit im Kontext von Verlust und Trauer. Basis hierfür sind zwei Interviewstudien mit Abschieds- und Trauerbegleiter*innen sowie trauernden Menschen. Die Autorinnen fokussieren, wie der Verlust der Intimität nach dem Tod von Partner oder Partnerin empfunden wird und wie Trauernde ihre Sexualität leben. Sie schaffen so Identifikationsmöglichkeiten für andere Trauernde und ermöglichen Angehörigen und Fachleuten der Trauerarbeit wertvolle Einblicke.

HUKUM MENGONSUMSI BIR 0% ALKOHOL PERSPEKTIF HUKUM ISLAM
Authors: Ginting Elvira Dewi
Published: March 2024

Bir berlabel alkohol 0% banyak beredar di pasaran, mulai dari supermarket, warung pengecer sampai dengan online shop. Para penjual menawarkan beragam merek dan jenis minuman yang di labeli sebagai bir beralkohol 0%. Namun tak sebanding dengan peredarannya yang semakin luas, bir berlabel alkohol 0% masih menyimpan banyak kontroversi di tengah masyarakat, terutama umat muslim. Mulai dari keabsahan label alkohol 0%, dampak mengonsumsinya dan juga hukum mengonsumsinya. sampai dengan apakah bir tersebut benar-benar mengandung kadar alkohol 0% sesuai dengan labelnya. Penelitian ini menggunakan jenis penelitian hukum normatif (legal research) karena bahan penelitian berasal dari data tertulis. Teknik pengumpulan datanya bertumpu kepada dokumen dan pustaka sebagai sumber data utama (library research) yang kemudian ditafsirkan dan diuraikan menggunakan metode penelitian kualitatif deskriptif. Hasil penelitian ini menunjukan bahwa dalam penentuan fatwa terkait dengan batas kadar alkohol dalam minuman, Komisi Fatwa MUI berlandaskan kepada al-Quran dan sunnah, dan mengikuti pendapat dari mayoritas Ulama yaitu mazhab Syafi’i, Hanabilah dan sebagian ulama Maliki karena segala sesuatu dapat dikategorikan sebagai khamr apabila dapat memabukan dan sedikit atau banyaknya adalah haram, berbeda dengan pendapat madzhab Hanafi yang hanya mengategorikan sesuatu sebagai khamr apabila terbuat dari anggur dan kurma. Namun apabila tidak terbuat dari bahan tersebut sekalipun dapat memabukan maka minuman itu bukan termasuk khamr. Keringanan terhadap halalnya minuman yang mengandung alkohol dibawah 0,5% hanya berlaku bagi minuman yang mengandung alkohol dari hasil sintesis kimiawi [dari petrokimia] ataupun hasil industri fermentasi non khamr. Minuman beralkohol yang masuk kategori khamr adalah najis dan hukumnya haram, sedikit ataupun banyak. Oleh karenanya MUI tidak menghalalkan minuman yang mengandung alkohol dari industri khamr meskipun kadar alkoholnya dibawah 0.5%.

RELATIVE TIME DELAY IN ACCELERATING ROTATING BLACKHOLE SPACETIME

The paper studies a potentially observable effect – relative time delay– on the background of the rotating accelerating black holes, called the C-metric. The C-metric proposed by Griffiths and Podolsky is an exact solution to Einstein's equations. The metric is characterized by mass, angular momentum and acceleration parameter, and is reduced to Kerr's solution when the acceleration parameter is zero. Relative time delay occurs if two light beams come from a variable source located behind a rotating gravitational lens. Passing on opposite sides of the lens, the rays arrive at the observer with a time difference. The time difference arises due to the frame dragging effect. Black holes described by the C-metric have the angular momentum which is necessary to occur the relative time delay. To calculate the relative delay of signals, the Dymnikova method was used. The xpression for the relative delay was expanded into a series to determine the influence of the acceleration parameter of the C-metric. It was found that the relative time delay in the leading order for the C-metric does not depend on the mass of black holes and the acceleration parameter, but depends only on the angular momentum. In the corrections, the relative time delay for the C-metric differs from the corrections to the delay in the Kerr solution by the influence of the free parameter of the C-metric. To estimate the influence of the acceleration parameter on the relative time delay, numerical delay values were obtained for a range of accelerations. Numerical values were calculated by substituting observed data from realistic pulsar–black hole configurations into the expression for the relative signal delay. The obtained numerical estimates show that the magnitude of the relative time delay in the first order is measurable with the capabilities of modern technology. Considering that all previously studied solutions of objects using relative delay had the influ- ence of mass, the numerical values of the delay in the C-metric are significantly different. Therefore, black holes described by the C-metric can be distinguished from previously studied black hole solutions using potential observations of relative time delay. However, the corrections containing the influence of the acceleration parameter are too small to take their influence into account.

In the modern world, there's a notable trend towards the active miniaturization of electronic devices. With technological advances enabling the manipulation of nanostructures, there's an increasing focus on exploring quantum effects pivotal to such designs. One distinguishing feature of nanostructures is the quantum nature of the electron's energy spectrum. This spectrum becomes discrete in directions where electrons move. Depending on the direction of this confinement, structures can be categorized as nanoplates, quantum wires, or quantum dots. The properties of such structures can significantly differ from those observed in large-scale systems. When discussing superconductivity, particular emphasis is placed on its macroscopic quantum properties.The influence on electronic wave functions is reflected in the characteristics of the superconducting state on broader scales. The Bardeen-Cooper-Schrieffer (BCS) theory is frequently utilized to analyze these nanostructures. The Gor’kov equations method serves as a potent tool for tasks related to the BCS theory. For instance, it can determine the parameters of the superconducting state, critical temperature, and current. Components of these equations, like Green's functions, are associated with various system properties. Research in the early stages of superconductivity studies revealed that the critical temperature (Tc ) – the temperature at which a material transitions to a superconducting state – can differ significantly between thin films and bulk materials. Intriguingly, reducing the film's thickness can both decrease (e.g., in niobium) and increase (e.g., in aluminum) the Tc value. This study delves into the quantum size effect in thin aluminum films, paving the way for materials with higher transition temperatures. Such advancements can simplify and make the maintenance of superconducting systems more cost-effective. In this study, a theoretical relationship between the critical temperature of a thin aluminum film and its thickness was derived. The Green's function method was chosen, which hadn't been previously employed for this computation. This approach offers greater potential compared to other superconductivity theory methods, presenting extensive avenues for theoretical exploration in this domain. The authors are confident that this work will contribute to further research on quantum dimensional effects in low-dimensional superconducting structures.

The depolarization currents of multilayer polymer films of polydiphenylene phthalide were measured using the thermally stimulated depolarization (TSD) method in the range from 170 to 400 K. The solution concentration was 2.5 and 5 wt.%. Each layer of polymer film was pre-dried at room temperature, then annealed in an oven. The number of layers of polymer film was 1, 2, 3 and 7 layers for 2.5 wt.%. and 1, 2, 3, 5 and 7 layers for 5 wt.%. The polarizing electric field strength was 2.5 × 105 V/cm. The rate of temperature change was 5 K/min. Based on experimental data, the dependence of the temperature of the position of the maximum peak of the depolarization current, the maximum values of the peaks of the depolarization currents, the values of the released charge and the activation energy of relaxation processes on the number of layers of the polymer film is shown. The temperature dependences of depolarization currents revealed two regions for a solution concentration of 2.5 wt.%. and one area for 5 wt.%. The first region is interpreted in the dipole charge approximation. The second region is explained by the presence of a wide distribution of traps occupied by injected charges. Interlayer polarization is observed in inhomogeneous dielectrics and is caused by differences in the electrical conductivity and dielectric constant of individual particles (or microparticles) of the dielectric. In such dielectrics, when an electric field is applied at the interface between its various components, charge will accumulate, which is equivalent to the creation of polarization. The results for the temperature dependences of the TSD currents of the samples showed that the total accumulated charge in the volume increases as the number of polymer layers increases. The reason for such a high concentration of trapped charges is most likely due to the presence of a wide distribution of traps occupied by injected charges. Moreover, the magnitude of the released charge is greater for samples prepared from a polymer solution with 2.5 wt. % This effect depends on the thickness of the polymer films. Namely, the thinner the films, the more charged particles penetrate the interface between the films.
THE PROBLEM OF A NONLINEAR FILTRATION PRESSURE FIELD IN AN ENVIRONMENT WITH A WEAKLY COMPRESSIBLE SKELETON

The solution of the problem of the pressure field during filtration of a compressible fluid in a porous medium with an incompressible skeleton in the presence of high-amplitude disturbances is presented. The equation describing pressure changes during field development takes into account the compressibility of the fluid and is presented in a nonlinear form. The known dependences of the density of the filtered medium on the pressure are approximated by a linear function. The movement is assumed to be one-dimensional and horizontal. The porosity, density and permeability of the porous medium skeleton, as well as the viscosity of the filtered medium are considered constant. The solution of the problem is found using an asymptotic expansion by a formal parameter added in the problem as a factor to the compressibility of the fluid. An approximate analytical solution of the nonlinear problem of the filtration pressure field in the zero and first approximations is found. The zero and first coefficients are represented by solutions of quasi-stationary equations, in which time is included as a parameter through the dimensions of the perturbation zone determined by the law of conservation of mass. It is established that taking into account the nonlinearity leads to a decrease in the size of the zone of disturbances of the pressure field. An approach to determining the upper boundary of the perturbation zone in nonlinear problems of this kind, which is based on the use of conservation laws, is proposed. It is shown that the special case of the zero approximation coincides with the solution of the linear problem obtained by the method of changing successive stationary states. The expressions found expand the possibilities of studying high-amplitude filtration processes, and the proposed approach removes the limitations of classical approaches associated with neglecting the dependence of fluid density on pressure in the divergent term of the continuity equation. The method used makes it possible to construct analytical expressions for decomposition coefficients orders of magnitude higher than the first, in addition, it creates the possibility of studying the contribution of nonlinearity caused by the dependence of permeability and viscosity on pressure.

Stemmacantha serratuloides (Georgi) M. Dittrich is a perennial herbaceous medicinal plant, a source of a number of phytoecdysteroids with adaptogenic, anabolic and tonic effects. Due to the rarity of this plant species and the strong dependence of its seed productivity on weather conditions, the relevance of research aimed at its biotechnological cultivation and reproduction is high. The aim of this study was to introduce S. serratuloides plants from the Cis-Ural population of the Republic of Bashkortostan into in vitro culture and to develop an effective protocol for micropropagation of this species. It was shown that an effective method of preparing seeds for in vitro culture is their successive sterilization with 96% ethanol (1 min) and 20% bleach (20 min), as well as me- chanical scarification, without a preliminary stratification step. When using 1 mg/l of 2,4-dichlorophenoxyacetic acid and 1.5 mg/l of 6-benzylaminopurine on Murashige-Skoog medium, no regeneration of shoots on explants of cotyledons and hypocotyls occurred. Shoot regeneration was induced from root explants using Murashige-Skoog medium supplemented with 6-benzylaminopurine and indoleacetic acid at concentrations of 1 mg/l and 1.5 mg/l, respectively. Rooting of shoots was carried out on MS medium containing 0.25 mg/L IAA. This micropropagation technology can be used for rapid propagation of plants for various biotechnological purposes, for example, for further transformation by Agrobacterium rhizogenes and creating of hairy root cultures.

Chaplain development in Clinical Pastoral Education (CPE) in healthcare settings in England: A mixed methods study
Authors: Szilagyi Csaba , Newitt Mark , Nuzum Daniel
Published: March 2024

Background:Clinical Pastoral Education (CPE) is the predominant specialised training for healthcare chaplains in several national contexts. CPE is spiritual care education that uses experiential and action-reflection learning methods to train diverse participants. However, CPE is not established for chaplaincy training in England. Currently, chaplaincy education in England lacks standardisation, leading to inequalities in entry into the profession and inconsistent training and career pathways. CPE has the potential to address these issues. We examined changes associated with participating in CPE and participants’ perceptions about their learning experience. We sought to evaluate the effectiveness of CPE as a viable chaplaincy education model in healthcare settings in England.Methods:Convergent mixed methods involved pre-post surveys and focus group sessions to examine the experiences and development of seven chaplains, with diverse experience levels and backgrounds, who participated in the pilot CPE unit in NHS England. We integrated thematic analysis and survey results.Results:We identified four overarching themes: Development pathways, Catalysts for development, Advantages of CPE for chaplaincy education, and Experiences with CPE course structure. Participants developed along various pathways: confidence, reflective practice, emotional intelligence, listening and attending skills, diversity in chaplaincy care, and spiritual assessment. Survey results confirmed several themes, indicating gains in chaplaincy capabilities, emotional intelligence, and counselling self-efficacy. Participants emphasised the advantages and effectiveness of the CPE model.Conclusions:Quantitative and qualitative findings converged to provide rich evidence that CPE generated personal and professional development, improving chaplaincy practice. General learning pathways moved from personal development, through the interpersonal learning context, and translated into chaplain competency. Participants endorsed CPE, as a robust and effective training model for chaplaincy in the English context, for those entering the profession and experienced chaplains alike. We conceptualised preliminary models for chaplain development and learning pathways in CPE that need validation and refinement by future research.

Authors: Cheraitia Mehdi
Published: March 2024

As artificial intelligence ecosystems become increasingly sophisticated and ubiquitous, there is a need to align their decisions and behavior with human values and objectives. We introduce a novel framework that maps behavioral and cultural "blueprints" to bridge personal and institutional realms. Enabling co-evolving human-AI understanding by integrating individual empowerment and organizational guidance through privacy-first dynamic meta-modeling. We demonstrate preservation of human agency via consent-driven analytics and systemic harmonization via an architecture personalizing human-AI interaction, by mapping a perception and societal’s multi-dimensional culture. We hope to generate individual and collective beneficial spark throughout our conclusions.
How Political Ideology and Media Shaped Vaccination Intention in the Early Stages of the COVID-19 Pandemic in the United States
Authors: Sarathchandra Dilshani , Johnson-Leung Jennifer
Published: March 2024

As a pharmaceutical intervention, vaccines remain a major public health strategy for mitigating the effects of COVID-19. Yet, vaccine uptake has been affected by various cognitive and cultural factors. We examine how a selected set of factors (i.e., knowledge, concern, media, peer influence, and demographics) shaped COVID-19 vaccination intention in the early phase of the pandemic (Fall 2020). Using a survey conducted in three US states (Idaho, Texas, and Vermont) just prior to the roll out of the first vaccines against COVID-19, we find that COVID-19 concern was the primary driver of vaccination intention. Concern was shaped mainly by two factors: political ideology and media sources. Yet, ideology and media were much more important in affecting concern for those who leaned politically conservative, as opposed to those who leaned liberal or remained moderate. The results from our Structural Equation Models affirm that the information politically conservative respondents were receiving reinforced the effects of their ideology, leading to a greater reduction in their concern. We discuss the potential implications of these findings for future pandemic preparedness.

Mechanical environment plays a crucial role in regulating bone regeneration in bone defects. Assessing the mechanobiological behavior of patient-specific orthopedic scaffolds in-silico could help guide optimal scaffold designs, as well as intra- and post-operative strategies to enhance bone regeneration and improve implant longevity. Additively manufactured porous scaffolds, and specifically triply periodic minimal surfaces (TPMS), have shown promising structural properties to act as bone substitutes, yet their ability to induce mechanobiologially-driven bone regeneration has not been elucidated. The aim of this study is to i) explore the bone regeneration potential of TPMS scaffolds made of different stiffness biocompatible materials, to ii) analyze the influence of pre-seeding the scaffolds and increasing the post-operative resting period, and to iii) assess the influence of patient-specific parameters, such as age and mechanosensitivity, on outcomes. To perform this study, an in silico model of a goat tibia is used. The bone ingrowth within the scaffold pores was simulated with a mechano-driven model of bone regeneration. Results showed that the scaffold’s architectural properties affect cellular diffusion and strain distribution, resulting in variations in the regenerated bone volume and distribution. The softer material improved the bone ingrowth. An initial resting period improved the bone ingrowth but not enough to reach the scaffold’s core. However, this was achieved with the implantation of a pre-seeded scaffold. Physiological parameters like age and health of the patient also influence the bone regeneration outcome, though to a lesser extent than the scaffold design. This analysis demonstrates the importance of the scaffold’s geometry and its material, and highlights the potential of using mechanobiological patient-specific models in the design process for bone substitutes.

Published: March 2024

Background: Developmental Coordination Disorder is a commonly occurring, but poorly recognised developmental condition characterised by difficulties with motor functions. Danish tests of children’s motor functioning, which are currently available, are outdated and only applicable up to the age of seven years old. New tools are needed to enable easy and efficient screening of motor difficulties experienced by children living in Denmark.Aims/Objectives: We aimed to translate and adapt the Developmental Coordination Disorder Questionnaire (DCDQ) into Danish.Materials and Methods: A team of translators prepared the Danish version of the DCDQ. In total, 36 parents completed the questionnaire. The children completed fine and gross motor coordination tasks. Concurrent validity was tested using Pearson correlation on the DCDQ and motor performance scores. Internal consistency was tested using Cronbach’s alpha.Results: The results show good concurrent validity (r=.311) and internal consistency (α=.80).Conclusions: The Danish version of the DCDQ is well suited for use with Danish-speaking parents.Significance: The tool will aid early assessment of motor difficulties in children of Danish-speaking parents. The Danish DCDQ can be used by educational, occupational and health professionals as well as researchers in national and international contexts.

Published: March 2024

Livestock farming which contributes 11 percent of the total GDP and 32 percent of agriculture GDP is mostly managed by farm household and small enterprise in Nepal. The study aims to analyze the economic rationale of livestock holding using the benefit-cost ratio of livestock farming by the household level and to assess the determinants of dairy cattle herd size in small farm households. The study was conducted in Dalchoki, a ward of Konjyosom rural municipality of Lalitpur district in the months of October and November, 2016. Structured questionnaires were used to collect data from 178 households using census method following the inclusion criteria as least five goat or a cow or a buffalo. Cost items included feeding cost, livestock purchasing cost, labour cost, insemination, veterinary cost, shed and equipment cost whereas benefit items consisted value of milk, live animal and meat and egg, draught power, value of manure among others. Linear regression was employed to examine the determinants of dairy cattle herd size. The results showed positive net benefit from animal husbandry with labor cost excluded and negative net benefit with labour cost included. The regression results showed that landholding size, remittance, net benefit, ethnicity and economically active family members have positive effect in determining size of the number of dairy cattle.
An Analysis of Implications of Remittances on The Economic Growth of Nepal
Authors: Adhikari Sabitri Devi Acharya
Published: March 2024

Migration and remittances are two themes that have received much attention among the policymakers in recent years in Nepal. The pressing need to understand the implication of this inflow of remittances on economic growth has become critical. Yet the existing literature produces inconclusive results. While some research reveals a favorable benefit, others show a negative implication on economic growth, creating the situation of policy uncertainty. This paper seeks to address this ambiguity by providing the fresh result into the implication of remittance from international migration on economic growth of Nepal. To examine this relationship, an ARDL model is employed for the yearly time series data of Nepal for the last 43 years. The analysis reveals co integration among remittances, GDP, total consumption, and capital formation of private sector. The findings reveal a positive impact of remittances on the short-run economy, indicating an immediate boost to economic growth. However, in the long run, as the influence of remittances exhibits a negative trend. It could lead to an 11% decrease in real GDP of Nepal in the long run if there is an increase in remittances by 10 percent. This study contributes to the existing body of knowledge by offering updated empirical evidence on the relationship between remittances and economic growth in Nepal.
