Rivers are vital water sources for human existence and environmental health. Due to freshwater scarcity, monitoring river water quality is crucial, especially concerningtotal suspended solids (TSS), which pose potential risks to health and the environment. Despite this importance, there is a lack of assessment of spatiotemporal TSS variation in Malaysia, particularly in Sungai Kuala Perlis. This study aims to evaluate spatial-temporal TSS variations in the surface water of Kuala Perlis, Perlis. Sampling points were GPS recorded in December 2021. Five sites were established for morning, afternoon, and evening sampling. Water samples were collected and subjected to gravimetric analysis using the American Public Health Assessment (APHA) standard. ANOVA (p=0.05) in SPSS version 26 found TSS ranges of 110.67 mg/L -177.67 mg/L, 27.67 mg/L – 132 mg/L, and 78 mg/L – 304.67 mg/L for morning, afternoon, and evening, respectively. Surprisingly, no significant mean TSS differences were found for temporal (p>0.05) or spatial (p>0.05) variations. Factors influencing TSS variation such as water flow, salinity, and anthropogenic activities, were discussed. These findings inform researchers, governments, and NGOs for future planning in Kuala Perlis, promoting river health and eco-friendly management

Published: January 2024

Objective: To compare serum Visfatin levels in Pakistani post-menopausal women having breast carcinoma with healthy women.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Physiology Department, Army Medical College, in collaboration with Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from Dec 2019 to Dec 2020.
Methodology: Eighty post-menopausal Pakistani women were included, out of which forty women were post-menopausal newly diagnosed and histologically confirmed cases of breast carcinoma awaiting their treatment. Menopause was confirmed through interviews and relevant history. Serum Visfatin levels were determined using an enzyme-linked immunosorbent assay (ELISA).
Result: Mean serum Visfatin levels were significantly higher in the Breast Carcinoma-Group (28.14±8.17 ng/ml) compared to the Healthy Control-Group (13.64±1.07 ng/ml). Moreover, serum Visfatin levels correlated positively with weight (r=0.735), body mass index (r=0.678), waist circumference(r=0.295) and waist-to-hip ratio (r=0.220).
Conclusion: Serum Visfatin levels were markedly elevated in post-menopausal women with breast carcinoma as compared toHealthy Controls. Higher serum Visfatin may be regarded as a potential risk factor in the development of breast carcinoma.
Multimodal teaching of accounting at the Durban University of Technology
Authors:   , Mahes Indira
Published: January 2024

The advancement and innovation of technology has made available a diversified array of modes to promote meaningful and engaging teaching in higher education in the discipline of accounting. A multimodal teaching approach recognises that teaching and learning occur through a range of modes that facilitate the uptake of a diversified portfolio of semiotic resources for meaning making. Students make meaning through a combination of modal resources, the selection of which is determined by individual learning styles. Disruptions to higher education globally can be mitigated through the adoption of multimodal pedagogy, a student-centred, flexible teaching approach, that enables the continuity of creative teaching practices in times of crisis. This study was undertaken to explore multimodal teaching of accounting in higher education, with Durban University of Technology as the case under study. The accounting discipline, being number intensive and technical, creates the perception that it is difficult to teach, more so digitally. The philosophical worldview underpinning this research study was pragmatism. The research design adopted was explanatory sequential mixed methods in two phases. The findings from data collected in the quantitative first phase, was used to inform the sampling and the type of semistructured questions to be asked in the qualitative second phase of the study. The target population encompassed all the academics in the accounting cluster within the Faculty of Accounting and Informatics. Quantitative data analysis was conducted using the Statistical Package for Social Sciences (SPSS), version 25 and included the use of descriptive and inferential statistics, while qualitative data analysis software, NVIVO was used to analyse qualitative data. The findings of this study revealed that general technological knowledge is very important for successful multimodal teaching of accounting, especially, understanding the technological infrastructure of the institution. Most academics considered knowledge on creating and uploading course content as essential for using Moodle. When using MS Teams, significance was accorded to being skilled at using complex applications and having knowledge on set up, conduct, and control of a digital lecture. Most accounting academics agreed that the accounting curriculum needed to be adapted to a moderate extent to facilitate curriculum realignment for multimodal teaching of accounting. Findings further revealed that the digital pedagogical skills of designing a digital learning environment, adapting pedagogy to digital channels, and creating a digital learning experience, were very necessary for teaching accounting using multiple modes.
The development of a computerised simulation model to guide the South African higher education sector in short and long-term planning of TEL infrastructure
Authors:   , Reddy Pregalathan
Published: January 2024

This study deals with the development of a computerised simulation model to guide the South African higher education (HE) sector in short and longterm planning of TEL (technology enhanced learning) infrastructure. A critical realist orientation was adopted, using a case study approach focusing on provision of TEL infrastructure at three Natal universities, namely, the Durban University of Technology, the University of KwaZuluNatal and Mangosuthu University of Technology. A mixed methods approach was used, combining qualitative with quantitative techniques, in order to collect data to establish key model specifications. The qualitative aspect comprised an online survey to obtain user feedback on the proposed computerised simulation. Quantitative methodology involved using functional decomposition design to extract the specifications from the data. The computerised simulation model was developed using a system dynamics approach which could define forecasting in operational terms, and thus offer various scenarios to guide institutional decision-makers in future planning. The systems model thus developed was then configured online using simulation software and tested out with key stakeholders. While computerised simulations currently exist in the area of infrastructural forecasting, the new contribution to the field is thought to be in forecasting the provision of TEL infrastructure.

Published: January 2024

The superior mesenteric artery syndrome (SMAS), also known as Wilkie’s syndrome, is a duodenal obstruction caused by the compression of the third part of the duodenum between the superior mesenteric artery (SMA) and the aorta. This condition often arises due to the disappearance of perivascular fatty tissue, as well as advanced stages of malnutrition and weight loss. Patients typically experience symptoms such as vomiting, fullness, and postprandial epigastric pain. While initial management involves conservative measures, surgery becomes necessary if symptoms do not improve. Here, we present the case of a 25-year-old man diagnosed with SMAS. Despite undergoing conservative management for three months, the symptoms did not regress. Subsequently, a laparoscopic duodeno-jejunostomy was performed, resulting in an uneventful postoperative period, disappearance of vomiting and epigastric pain, and a weight gain of 14 kg after one year.

Thoracoscopy was inspired by the therapy of collapsed lung at the beginning of the 20th century in the epidemic of pulmonary tuberculosis. Minimally invasive surgery is increasingly becoming the first treatment proposal for left congenital diaphragmatic hernia. A two-year-old child was hospitalized for a congenital diaphragmatic hernia, revealed late in the neonatal period; the preoperative preparation consisted in stabilizing the child on the hemodynamic and respiratory level, he benefited surgical repair by thoracoscopy, treatment of postoperative pain like any thoracic surgery. Normal feeding was obtained in 24 hours. Diaphragmatic hernia diagnosis out of neonatal period represents a polymorphism of symptoms including strangulation, can be diagnosed at any age, the left posterolateral form is the most common form. Thoracoscopy was indicated as a first-line treatment given the small volume of gas insufflation sufficient to create a wide operating field with a collapsed lung. Cardiorespiratory intolerance is very rare with a small pressure, with a small volume and an insufflation stop as soon as the pressure of 6 mmHg is maintained.

ANALISIS PENGARUH PEMBUKAAN KATUP TERHADAP KINERJA TURBIN AIR
Authors: DARWIS MUH.
Published: January 2024

Utilization of water energy is carried out using water turbines that utilize waterfalls or river water flows. The amount of hydropower available from a water source depends on the water head and discharge. The type of turbine used in this research is a kinetic turbine whose shaft is placed vertically, where The water directly hits the blades on one half of the turbine wheel while the other half also gets hit but not as much as the first half so the turbine can still spin. This research was carried out by flowing water fluid into a water channel that had been prepared using a pump. The flowing fluid was created into turbulence so that the conditions were considered the same as the conditions of a flowing river. The water flow is set from 20 m3/hour, 22 m3/hour, 24 m3/hour, 26 m3/hour and 28 m3/hour, while the turbine rotation braking is varied from 80 rpm, 60 rpm, 40 rpm, 20 rpm and 10 rpm . This test was carried out to obtain data on rotation (n), force (F) and calculation of the flow velocity at the inlet at the end of the flow director (V),Maximum power is obtained at a runner speed of 60 rpm with a flow rate of 28 m3/hour of 4,284 watts,Maximum efficiency was obtained at a runner speed of 60 rpm with a flow rate of 28 m3/hour of 26.373%. The greater the flow of water flowing into the turbine blades, the greater the resulting turbine power and efficiency. Furthermore, the greater the rotation of the turbine runner, the greater the resulting turbine power and efficiency.

Published: January 2024

A terapia gênica, que envolve a introdução, alteração ou correção do material genético dentro das células de um indivíduo para tratar uma doença, tem despertado interesse dentro da comunidade científica, principalmente para o tratamento de doenças monogênicas. O presente trabalho tem como objetivo abordar as informações mais relevantes acerca da terapia genética no tratamento da fibrose cística (FC). Este estudo é do tipo revisão sistemática e incluiu pesquisas publicadas entre 2013 e 2023 nas bases SCIELO, LILACS, MEDLINE e PUBMED. Foram destacados 9 artigos para compor essa revisão. As informações mais relevantes evidenciam que a adição, inativação e edição de genes são as técnicas utilizadas na terapia genética, e dentre as nucleases mais utilizadas encontram-se: zinc-finger nucleases, transcription activator-like effector nucleases e clustered regularly interspaced short palindromic repeats associado a nucleases Cas9, sendo esta última a mais promissora. As vantagens e desvantagens dependem principalmente do tipo de vetor utilizado para a veiculação de genes terapêuticos, sendo que os vetores virais se destacam pela eficiência na entrega de material genético, contudo estão mais relacionados com respostas imunitárias. É imprescindível considerar as questões éticas, como consentimento informado, possíveis efeitos adversos e a equidade no acesso à terapia genética. Em suma, a terapia genética apresenta um potencial significativo no tratamento da FC, abrindo caminho para uma cura efetiva. Contudo, o sucesso dessa abordagem depende não apenas de avanços científicos, mas também da abordagem cuidadosa de questões éticas. O progresso nesse campo é promissor, oferecendo esperança para uma nova era no tratamento da FC.

Statistical characterization of erosion and sediment transport mechanics in shallow tidal environments – Part 1: Erosion dynamics
Authors: D'Alpaos Andrea , Tognin Davide , Tommasini Laura , D'Alpaos Luigi , Rinaldo Andrea , Carniello Luca
Published: January 2024

Abstract. Reliable descriptions of erosion events are foundational to effective frameworks relevant to the fate of tidal landscape evolution. Besides the rhythmic, predictable action of tidal currents, erosion in shallow tidal environments is strongly influenced by the stochastic wave-induced bottom shear stress (BSS), mainly responsible for sediment resuspension on tidal flats. However, the absence of sufficiently long, measured time series of BSS prevents a direct analysis of the combined tide- and wave-driven erosion dynamics and its proper representation in long-term morphodynamic models. Here we test the hypothesis of describing erosion dynamics in shallow tidal environments as a Poisson process by analysing, with the peak-over-threshold theory, the BSS time series computed using a fully coupled, bi-dimensional numerical model. We perform this analysis on the Venice Lagoon, Italy, taking advantage of several historical surveys done in the last 4 centuries, which allow us to investigate the effects of morphological modifications on spatial and temporal erosion patterns. Our analysis suggests that erosion events on intertidal flats can effectively be modelled as a marked Poisson process in different morphological configurations because the interarrival times, durations, and intensities of the over-threshold exceedances are always well described by exponentially distributed random variables. The resulting statistical characterization allows a straightforward computation of morphological indicators, such as the erosion work, and paves the way for a novel synthetic, yet reliable, approach for the long-term morphodynamic modelling of tidal environments.
Statistical characterization of erosion and sediment transport mechanics in shallow tidal environments – Part 2: Suspended sediment dynamics
Authors: Tognin Davide , D'Alpaos Andrea , D'Alpaos Luigi , Rinaldo Andrea , Carniello Luca
Published: January 2024

Abstract. A proper understanding of sediment resuspension and transport processes is key to the morphodynamics of shallow tidal environments. However, a complete spatial and temporal coverage of suspended sediment concentration (SSC) to describe these processes is hardly available, preventing the effective representation of depositional dynamics in long-term modelling approaches. Through aiming to couple erosion and deposition dynamics in a unique synthetic theoretical framework, we here investigate SSC dynamics, following a similar approach to that adopted for erosion (D'Alpaos et al., 2024). The analysis with the peak-over-threshold theory of SSC time series computed using a fully coupled, bi-dimensional model allows us to identify interarrival times, intensities, and durations of over-threshold events and test the hypothesis of modelling SSC dynamics as a Poisson process. The effects of morphological modifications on spatial and temporal SSC patterns are investigated in the Venice Lagoon, for which several historical configurations in the last 4 centuries are available. Our results show that, similar to erosion events, SSC can be modelled as a marked Poisson process in the intertidal flats for all the analysed morphological lagoon configurations because exponentially distributed random variables describe over-threshold events well. Although erosion and resuspension are intimately intertwined, erosion alone does not suffice to describe also SSC because of the non-local dynamics due to advection and dispersion processes. The statistical characterization of SSC events completes the framework introduced for erosion mechanics, and together, they represent a promising tool to generate synthetic, yet realistic, time series of shear stress and SSC for the long-term modelling of tidal environments.

Abstract. Climate change and water security are among the grand challenges of the 21st century, but literacy on these matters among high-school students is often unsystematic and/or detached from the real world. This study aims to introduce the educational objectives, methods, and early results of “Water and Us”, a three-module initiative that can contribute to advancing water education in a warming climate by focusing on the natural and anthropogenic water cycle, climate change, and emerging water conflicts. The method of Water and Us revolves around storytelling to aid understanding and generate new knowledge, learning by doing, a flipped-classroom environment, and a constant link to examples from the real world (such as ongoing droughts across the world or seeds of conflict regarding transnational river basins). Water and Us was established in 2021–2022 and, during that school year, involved ≥200 students as part of a proof of concept to test the complete didactic approach using small-scale experiments. Results from ≥40 h of proof-of-concept events confirmed the effectiveness of this approach with respect to conveying the essential elements of the natural and anthropogenic water cycle, the most commonly recurring concepts related to climate change and water as well as the possible conflicts and solutions related to water scarcity in a warming climate. The Water and Us team remains interested in networking with colleagues and potential recipients to upscale and further develop this work.
Modeling apparent Pb loss in zircon U–Pb geochronology
Authors: Sharman Glenn R. , Malkowski Matthew A.
Published: January 2024

Abstract. The loss of radiogenic Pb from zircon is known to be a major factor that can cause inaccuracy in the U–Pb geochronological system; hence, there is a need to better characterize the distribution of Pb loss in natural samples. Treatment of zircon by chemical abrasion (CA) has become standard practice in isotope dilution–thermal ionization mass spectrometry (ID-TIMS), but CA is much less commonly employed prior to in situ analysis via laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) or secondary ionization mass spectrometry (SIMS). Differentiating the effects of low levels of Pb loss in Phanerozoic zircon with relatively low-precision in situ U–Pb dates, where the degree of Pb loss is insufficient to cause discernible discordance, is challenging. We show that U–Pb isotopic ratios that have been perturbed by Pb loss may be modeled by convolving a Gaussian distribution that represents random variations from the true isotopic value stemming from analytical uncertainty with a distribution that characterizes Pb loss. We apply this mathematical framework to model the distribution of apparent Pb loss in 10 igneous samples that have both non-CA LA-ICP-MS or SIMS U–Pb dates and an estimate of the crystallization age, either through CA U–Pb or 40Ar/39Ar geochronology. All but one sample showed negative age offsets that were unlikely to have been drawn from an unperturbed U–Pb date distribution. Modeling apparent Pb loss using the logit–normal distribution produced good fits with all 10 samples and showed two contrasting patterns in apparent Pb loss; samples where most zircon U–Pb dates undergo a bulk shift and samples where most zircon U–Pb dates exhibited a low age offset but fewer dates had more significant offset. Our modeling framework allows comparison of relative degrees of apparent Pb loss between samples of different age, with the first and second Wasserstein distances providing useful estimates of the total magnitude of apparent Pb loss. Given that the large majority of in situ U–Pb dates are acquired without the CA treatment, this study highlights a pressing need for improved characterization of apparent Pb-loss distributions in natural samples to aid in interpreting non-CA in situ U–Pb data and to guide future data collection strategies.
An assessment of potential improvements in social capital, risk awareness, and preparedness from digital technologies

Published: January 2024

Abstract. Contributions to social capital, risk awareness, and preparedness constitute the parameters against which applications of digital technologies in the field of disaster risk management should be tested. We propose here an evaluation of four of these: mobile positioning data, social media crowdsourcing, drones, and satellite imaging, with an additional focus on acceptability and feasibility. The assessment is carried out through a survey disseminated among stakeholders. The frame of the analysis also grants the opportunity to investigate to what extent different methodologies to aggregate and evaluate the results, i.e., the Criteria Importance Through Criteria Correlation (CRITIC) model, the (Euclidean)-distance Criteria Importance Through Criteria Correlation (dCRITIC) model, the entropy model, the mean weight model, and the standard deviation model, may influence the preference of one technology over the others. We find that the different assumptions on which these methodologies rely deliver diverging results. We therefore recommend that future research adopt a sensitivity analysis that considers multiple and alternatives methods to evaluate survey results.

Convergence of scaffold-guided bone regeneration principles and reconstructive surgery: A regenerative matching axial vascularisation approach to the load-bearing long bone defect
Authors:   , Sparks David S.
Published: January 2024

Functional reconstruction of large volume bone loss in the limbs is demanding. Reconstructive approaches available have variable success and novel approaches, such as those incorporating tissue engineering methods, are required. The thesis describes and evaluates the rare bench-to-bedside translation of a novel tissue engineering technique, termed Regenerative Matching Axial Vascularisation (RMAV), to reconstruct major bone loss in the load-bearing limb where contemporary surgical options are limited. The work described takes the marriage between scaffold-guided tissue regeneration and modern surgical practice to new heights.
Restless skies at the turn of the first Millennium AD. Climate fluctuations, astronomic phenomena and socio-political turbulences in 10th and 11th century Byzantium and Japan in comparative perspective
Authors: Preiser-Kapeller Johannes
Published: January 2024

Around the turn of the first Millennium AD, both in Christian polities such as the Byzantine Empire as well as in regions with Buddhist communities such as in Heian Japan, expectations of an end of times emerged. Although based on different religious and independent chronological interpretations, they gained attraction at the same time due to the parallel observation and interpretation of the same astronomical phenomena (such as sightings of Halley´s comet in 989 AD) or of simultaneous climate anomalies, which can partly be connected with the Oort Solar Minimum of the 11th century. This paper explores and compares the interplay between natural phenomena, religious and political unrest, apocalyptic interpretations and individual decision-making for Byzantium and Japan on the basis of historical and natural scientific evidence.
