Authors: Kadhim Ishraq Abd Ulrazzaq
Published: February 2023

The current study involves synthesis of a composite films of sodium alginate (Alg), polyvinylalcohol and NanoGraphene oxide (GO) for tissue engineering applications. Solvent casting was used to make the polymeric composite films (Alg-Pva-Go), which may exhibit a synergic activity of the components for tissue repair. The influence of various GO concentrations on the films properties was also investigated. The scaffold has outstanding physicochemical and biological properties. The composite film's high swelling degree and contact angle reveals its high hydrophilicity, making it appropriate for tissue engineering. The antimicrobial activity on Staphylococcus aureus were studied. Furthermore, the antimicrobial test showed that the films composite was resistant to S. aureus. Seeding (AD-MSC) cells into the composite films exhibited an increase in cell adhesion and proliferation when compared to the Alginate and Polyvinylalcohol film in vitro experiments, indicating that the GO has a good influence on the films characteristics, which can utilization in tissue engineering applications.

Authors: Mohammed Dhuha Hussain , Jassim Raghdaa Kareem
Published: February 2023

Background: zirconium (Zr) implants are known for having an aesthetically pleasing tooth-like colour Unlike the grey cervical collar that develops over time when titanium (Ti) implants are used in thin gingival biotypes. However, the surface qualities of Zr implants can be further improved. This present study examined using thermal vapour deposition (TVD) to coat Zr implants with germanium (Ge) to improve its physical and chemical characteristics and enhance soft and hard tissue responses. Materials and methods: Zr discs were divided into two groups; the uncoated (control) group was only grit-blasted with alumina particles while the coated (experimental) group was grit-blasted then coated with Ge via TVD. Field emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), atomic force microscopy (AFM), water contact angle test, and cross-hatch adhesion tests were then used for surface characterization Results: An XRD analysis of the Ge-coated Zr samples revealed the substrate while the FESEM results revealed a continuous coating with no cracks. The mean surface roughness and hydrophilicity of the Ge-coated Zr substrate was significantly higher than that of the uncoated Zr substrate (P≤0.01). The cross-hatch adhesion of all the samples was 0%, thereby indicating good coating adhesion. Conclusion: Therefore Coating Zr implants with Ge via TVD enhances its physical and chemical properties.

Authors: Acharya Preetam Rajgopal , Sharma Deepthi , Kamath Sindhu , Shenoy Sajjan , Magazine Rahul
Published: February 2023

Microscopic polyangiitis (MPA) is an antineutrophil cytoplasmic autoantibody-associated vasculitis, usually affecting the small vessels in the form of systemic necrotizing vasculitis. It commonly manifests as diffuse alveolar hemorrhage and rapidly progressive glomerulonephritis but may present with the involvement of multiple organs. Timely diagnosis at an early localized stage is crucial for instituting an early disease-specific treatment. We report a case of a 63-year-old female who was diagnosed with MPA predominantly involving lungs and middle ears. The absence of a typical pulmonary–renal presentation and clinical features favoring obstructive airway disease and tuberculosis led to a delayed diagnosis. The presence of antimyeloperoxidase antibodies in high titer and a clinical response to monoclonal antibody therapy, thereby confirming the diagnosis of MPA prompted us to report this case.

Authors: Paul Gowranga Kumar , Swapon Md. Shalauddin , Kaderi Kibria K. M.
Published: February 2023

BACKGROUND:

The prevalence of self-medication is high in Bangladesh due to easy access and poor regulatory controls over these drugs. Our study aimed to assess the attitude of university students in Bangladesh toward antibiotic usage, especially their knowledge and awareness about antibiotics and their resistance. We also evaluated the determinants behind their attempts at drug intake without prescription.

MATERIALS AND METHODS:

A cross-sectional study was conducted in Mawlana Bhashani Science and Technology University that included information from randomly selected 200 students from 15 departments using a structured questionnaire. The statistical analyses were performed by using SPSS software (version 21) and R programming.

RESULTS:

The study revealed that 61.0% of the students use self-medication at different times or always; 32.5% of the respondents keep antibiotics for future use, and 38% of the students think it is right to stop antibiotics when symptoms are improving. Half of the participants (47.5%) use antibiotics based on their previous experience. The criteria of antibiotic selection have a significant relationship with knowledge about antibiotic resistance (P = 0.017) and altered prescribed medicine without doctor's advice (P < 0.001). The multivariate analysis indicates that respondents who know about antibiotic resistance select antibiotics from the community pharmacists with respect to their own experience 5.102 times higher than those who do not know about antibiotic resistance.

CONCLUSIONS:

The study mainly explored the knowledge gaps of the students on the options that are responsible for antibiotic resistance in the community and found that students have mid-level knowledge (66%) about antibiotic resistance.

Published: February 2023

BACKGROUND:

With the emergence of COVID, we are forced to use e-learning in form of arranging online classes for students. Medical educators all over the world are conducting online classes for students. This study aimed to evaluate the perception of online learning among MBBS students and teachers through a questionnaire-based survey.

MATERIALS AND METHODS:

A cross-sectional study was done in the AIIMS, Bhopal. The study was based on questionnaire (online Google form) response received from 43 number of faculty and 156 number of students.

STATISTICAL ANALYSIS USED:

Chi-square test and unpaired t-test were used for statistical analysis using statistical software Systac 13.2.

RESULTS:

Handling software, technical issues, and lack of face-to-face interaction were more significant problems in students compared to faculty. The desire for the social site which causes disturbances in learning was a significant problem in the students compared to faculty. Giving and taking assessment problem was reported by 60% and 63.8% of faculty and students, respectively (P = 0.67). Both groups preferred the Google Classroom platform (P = 0.16). Students (65.3%) preferred audiovisual recording, while faculty (72%) preferred PowerPoint with narration. PowerPoint presentation without narration was the least preferred (10.8%). Both groups stressed the importance of training (P = 0.17) and infrastructure development (P = 0.85). Students, as well as faculty, strongly discouraged e-learning for practical/clinical teaching.

CONCLUSIONS:

Students, as well as faculty, have mixed reactions toward e-learning. Most importantly affected in the present scenario is practical/clinical teaching and assessment. Every attempt needs to be done to strengthen infrastructure and impart training to students and faculty.
The shadow of paternalism on patient-centeredness in oncology nursing care
Authors: Taleghani Fariba , Farzi Saba , Yazdannik Ahmadreza , Esfahani Mehran Sharifi
Published: February 2023

BACKGROUND:

Patient-centered care (PCC) is a key component of high-quality care. Given the different effects of cancer on patients, patient-centeredness is very important in oncology nursing care. The aim of this study was to explore nurses’ perceptions of the patient-centered in oncology nursing care.

MATERIALS AND METHODS:

This descriptive qualitative study was conducted in 2018–2020, Iran. Data collection methods included observation and semi-structured interviews. Patient, family, and nurse behaviors were observed (total: 318 h). In addition, interviews were conducted with nurses and nursing managers (12 interviews). Data analysis was performed using Graneheim and Lundman's approach.

RESULTS:

Data analysis resulted in the emergence of four themes: “Organizational structure as a barrier to the PCC,” “Lack of institutionalization of PCC in nurses,” “Understanding and paying attention to the patient as PCC,” and “Situational PCC.” The final theme of this study is “PCC in the shadow of paternalism.”

CONCLUSIONS:

The paternalism approach in the context of oncology nursing care has made the realization of PCC difficult. The first step to promote PCC is increasing nurses’ awareness of the impact of paternalism on patient-centeredness. Providing patient-centered oncology nursing care requires changing attitudes, values, and behaviors at individual, professional, and organizational levels.

Decarbonized Fuel Options for Long-haul Commercial
Vehicles
Authors: Muelaner Jody Emlyn
Published: February 2023

Most heavy trucks should be fully electric, using a combination of batteries and
catenary electrification, but heavy trucks requiring very long unsupported range
will need chemical fuels. At the scale of heavy trucks, compressed hydrogen can
match the specific energy of diesel, but its energy density is five times lower,
limiting range to around 2,000 km. Scaling green hydrogen production and
addressing leakage must be priorities. Hydrogen-derived electrofuels—or
“e-fuels”—have the potential to scale, and while the economic comparison
currently has unknowns, clean air considerations have gained new importance

The FastVRP automatic platform for the thermal monitoring of volcanic activity using VIIRS and SLSTR sensors: FastFRP to monitor volcanic radiative power
Authors: Torrisi Federica , Amato Eleonora , Corradino Claudia , Del Negro Ciro
Published: February 2023

Satellite thermal remote sensing is widely used to detect and quantify the high-temperature vol- canic features produced during an eruption, e.g. released radiative power. Some space agencies provide Fire Radiative Power (FRP) Products to characterize any thermal anomaly around the world. In particular, Level-2 FRP Products of the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Sea and Land Surface Temperature Radiometer (SLSTR) are freely available online and they allow to monitor high-temperature volcanic features related to the dynamics of volcanic activity. Here, we propose the FastVRP platform developed in Google Colab to process automatically the FRP Products provided by the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) space agencies. FastVRP was designed to monitor the volcanic radiative power (VRP) related to eruptive activity of Mt. Etna (Sicily, Italy). We compared the quality of these FRP Products during a number of recent paroxysmal lava fountains occurred at Etna volcano between February and March 2021. We highlighted the advantages and the limits of each sensor in monitor- ing intense volcanic eruptions lasting a few hours. Furthermore, we combine the mid-high spatial/ low temporal resolution VIIRS and SLSTR with the low spatial-high temporal resolution SEVIRI (Spinning Enhanced Visible and Infrared Radiometer Imager) to improve estimates of the energies released from each paroxysmal episode. In particular, we propose a fitting approach to enhance the accuracy of SEVIRI low spatial-high temporal resolution measurements exploiting the few acqui- sitions from VIIRS and SLSTR high spatial-low temporal resolution during lava fountain cooling phase. We validated the radiative power values forecasted from VIIRS and SLSTR with the radiative power values retrieved using MODIS (Moderate Resolution Imaging Spectroradiometer) sensor.

The lambda-Pi-calculus modulo theory is a logical framework in which many
type systems can be expressed as theories. We present such a theory, the theory
U, where proofs of several logical systems can be expressed. Moreover, we
identify a sub-theory of U corresponding to each of these systems, and prove
that, when a proof in U uses only symbols of a sub-theory, then it is a proof

Published: February 2023

Changes in educational paradigms have affected the understanding of how individuals learn. The emergence of Covid-19 has created unprecedented disruption in the education systems. This study attempts to analyse students' perceptions of their learning profile before and after Covid-19, using two different cohorts of students from five schools. Participated in October 2019 (first application) 369 students, and in November 2021 (second application) 294 students. These are students of two educational cycles: grades 7-9 and 10-12. The Effective Lifelong Learning Inventory questionnaire has seven dimensions: ‘moving and learning’, ‘critical curiosity’, ‘making sense’, ‘creativity’, ‘learning relationships’, ‘strategic awareness’, ‘resilience’; and it was administered to understand how students self-assess their learning profile. Descriptive and inferential statistics were calculated to analyse the data and detect possible differences in the learning profiles. The results show that students in grades 7-9 seem to have been the most affected by Covid-19 (means were statistically significant in all dimensions except ‘resilience’) when compared to students in grades 10-12 (statistically significant only in ‘critical curiosity’, ‘learning relationships’ and ‘meaning making’ dimensions). In conclusion, the learning profiles have changed between the applications in both cycles. A higher percentage of students rated themselves worse in almost all dimensions in the second application. However, the increased autonomy during Covid-19 could explain the average increases in 'resilience' in grades 7-9 and 'creativity' in grades 10-12 from the first to the second application.
Keywords: grades 7-9; grades 10-12; learning power; learning provisions; effective lifelong learning inventory; covid-19.

Authors:   , Rios Heloiza Chaves
Published: February 2023

O presente trabalho desenvolve uma ferramenta de acompanhamento dos egressos da pós- graduação da Universidade Federal de Viçosa, com o objetivo de possibilitar o acompanhamento e análise da trajetória profissional deles ao longo dos anos. Assim, será possível suscitar indicadores que assegurem o aprimoramento das ações institucionais, avaliar se os objetivos e metas dos programas de pós-graduação estão sendo cumpridos e, potencialmente, favorecer a melhoria na conceituação deles perante a CAPES. A partir da manutenção do vínculo egresso-instituição e instituição-egresso, se estabelece um processo de troca de experiências, mecanismos de retroalimentação de informações, conhecimentos científicos e sociais. Assim, também será possível entender melhor os indivíduos que circulam dos corredores às salas de aula, nos laboratórios, nos espaços físicos da instituição, construindo soluções que tornem perceptível para os estudantes sua importância para a instituição. O patrimônio cultural não se limita à materialidade, mas também às experiências e memórias, coletivas ou individuais, e à recuperação de histórias de vida. Nesse sentido, foi necessário pesquisar a evolução do conceito de patrimônio cultural, patrimônio da ciência e tecnologia, patrimônio afetivo e entender como inserir novos atores no processo de patrimonialização no sentido de reforçar o vínculo profissional e afetivo entre o egresso e sua instituição de formação. Palavras-chave: Patrimônio cultural. Patrimônio da ciência e tecnologia. Patrimônio afetivo. Gestão de documento. Egresso.

Modelling ship strike risk to fin, humpback and killer whales in British Columbia, Canada
Authors: Williams Rob , O'Hara Patrick
Published: February 2023

Many cetacean species are susceptible to mortality or serious injury from vessel collisions. Spatially explicit assessments of risk per whale can help identify potential problem areas to guide appropriate mitigation measures. Canada’s Pacific waters host high cetacean densities and intense maritime traffic, and the issue of vessel collisions has taken on a high priority in British Columbia (BC) recently due to several major industrial development applications. Spatially-explicit statistical modelling and Geographic Information System (GIS) visualisation techniques identified areas of overlap between shipping activity and waters used by humpback, fin and killer whales. Areas of highest risk were far removed from areas with highest concentrations of people, suggesting that many beach-cast carcasses could go undetected. With few exceptions, high-risk areas were found in geographic bottlenecks, such as narrow straits and passageways. Port expansion and a proposed pipeline for carrying oil from Alberta to BC’s north coast (with associated oil tanker traffic) would increase ship strike risk for all three species. The risk assessments illustrate where ship strikes are most likely to occur, but cannot estimate how many strikes occur. Propeller wounds on live killer whales are common in the region, and fatal collisions have been reported in BC for all three species. Procedures were used to estimate potential mortality limits in accordance with a wide range of quantitative management objectives from jurisdictions around the world. While the extent of under-reporting of ship strikes has not been evaluated, the few known cases of collisions involving fin whales suggest that mortality due to ship strike for this species may already be approaching or even exceeding mortality limits under the most risk-averse management objectives. It is hoped that risk maps may inform environmental impact assessments of marine traffic because it will be easier to plan new shipping lanes so that they avoid high-density areas for whales than it will be to move the lanes after they become entrenched.

Population size and annual survival probabilities for the killer whales (Orcinus orca) inhabiting the inshore waters of Possession Island, Crozet Archipelago, southern Indian Ocean, were estimated through mark-recapture modelling. Capture histories were generated from a set of photographs taken under a photo-identification protocol and a set of photographs taken opportunistically, between 1964 and 2002. Photographs were selected according to their intrinsic quality and the degree of natural marking of individuals. Under those conditions, only well-marked individuals were considered as ‘marked’ from a capture-recapture perspective. The purpose of this double selection was to minimise identification errors and reduce the heterogeneity of capture probabilities. Abundance estimates were derived from the Mth sequential model for closed populations and adjusted for the proportion of well-marked individuals in the study population and for the number of photo-identified individuals. Under this framework, estimates of 98 (95% CI 70-156) individuals in 1988-89, and 37 (95% CI 32-62) individuals in 1998-2000 are proposed. After a weighted model averaging, the Cormack-Jolly-Seber models with the strongest support from the data produced low survival probability estimates, decreasing from 0.935 (95% CI 0.817-0.979) to 0.895 (95% CI 0.746-0.961) for males, and from 0.942 (95% CI 0.844-0.980) to 0.901 (95% CI 0.742-0.966) for females over the period 1977-2002. A Jolly-Seber model was used as a ‘second opinion’ model. It confirmed the worrying status of the population with a constant survival probability estimated at 0.89 (95% CI 0.84-0.93) and a constant rate of increase (applying to the well-marked fraction of the population) estimated at 0.94 (95% CI 0.90-0.99) for the period 1987-2000. This rate of increase is consistent with the abundance estimates presented here. Possible violations of the underlying model assumptions were investigated and it was concluded that the abundance estimates for the period 1988-89 and the CJS survival estimates should be the most reliable results. It is feared that the killer whales around Possession Island are in sharp decline, as may be true for the whole Crozet Archipelago. The effect of low prey stocks and lethal interactions with fisheries as the most likely causes of this decline are discussed.

Images of 120 individual bottlenose dolphins from around the Irish coast were obtained from three photo-identification catalogues. Twenty three individuals were subsequently re-sighted, which is a re-sighting rate of 19%. The distance between re-sightings ranged from 130 to 650km and the duration from 26 to 760 days. Images were also compared to a catalogue of resident dolphins from the Shannon Estuary candidate Special Area of Conservation and from Wales but no matches were found. This short study provides strong evidence that bottlenose dolphins in Irish coastal waters are regularly undertaking large movements around the entire Irish coast and must be considered highly mobile and transient. These results have important implications for the conservation and management of this species.
A simulation-based approach to evaluating population structure in non-equilibrial populations

The standard null model of panmixia used to test for population subdivision is based on a set of assumptions that can be violated given recent events likely to result in non-equilibrial genetic composition coupled with the complex life histories of many species. Bowhead whales (Balaena mysticetus) represent such a species. Bowhead whales also have a well-documented history of severe commercial harvest in the recent past which would be expected to leave a population out of genetic equilibrium. They also have a very long life span, overlapping generations, and age and sex-structured migrations. In addition, samples come from whales killed in a hunt known to be non-random with respect to size at different whaling villages. Sampling of such a population could lead to erroneous conclusions regarding population structure, which could have real consequences for aboriginal whaling. To better interpret the results of standard population genetic analyses, an individual-based model of bowhead whale population dynamics and genetics was created using the R package rmetasim. The model re-created as closely as possible all aspects of the demography, genetics, and whaling history of bowhead whales. Simulated datasets were generated by sampling from the simulated population in a way that matched the age, sex and geographic distribution of empirically collected samples. The empirical bowhead datasets were compared to null distributions generated from the simulated datasets for a variety of genetic analyses. The analysis indicates that the empirical genetic data sampled from the Bering-ChukchiBeaufort (BCB) stock of bowhead whales are more consistent with the model of a population with the same whaling history and demographic composition as BCB whales than they are with a single, randomly-mating population in genetic equilibrium under a standard Wright-Fisher model. Additionally, it was demonstrated that by failing to account for the unique features of the population dynamics of the species, standard tests of genetic differentiation based on panmixia may produce misleading results. The approach outlined will likely prove useful for evaluating population structure in other species likely to be out of equilibrium.
Increasing numbers of ship strikes in the Canary Islands: proposals for immediate action to reduce risk of vessel-whale collisions
Authors: Carrillo Manuel , Ritter Fabian
Published: February 2023

The Canary Islands, known for their extraordinarily high cetacean species diversity, have witnessed a rapid expansion in fast and high speed ferry traffic during the past few years. At the same time, ship strikes have been increasingly reported. 556 cetacean carcasses, found ashore, or reported, in the Canary Islands between 1991 and 2007, were examined. 59 strandings (10.6%) were found to involve vessel-whale collisions, the great majority of strandings (58%) occurred on Tenerife. Species most affected were sperm whales (Physeter macrocephalus, n = 24, 41%), pygmy sperm whales (Kogia breviceps, n = 10, 17%), Cuvier’s beaked whales (Ziphius cavirostris, n = 7, 12%), short-finned pilot whales (Globicephala macrorhynchus, n = 6, 10%) and at least three baleen whale species (n = 9, 15%). Twenty six animals (44%, n = 42) were either calves or juveniles, and one was a newborn. The temporal distribution of strandings indicates that lethal strikes have increased in recent years. Most ship strikes, assumingly by large and fast moving vessels, probably resulted in the death of the animals, as indicated by severe injuries such as huge slashes, cuts, broken vertebrae or animals separated into halves. Given these numbers and the widely accepted fact that only a portion of ship strikes will be recorded due to under-reporting and carcasses drifting away or sinking, ship strikes appear to be a major threat to cetaceans in the Canary Islands, especially to sperm whales. Moreover, the issue is a matter of human safety, as crew and passengers are at risk of being harmed, too. In this situation, a number of measures to mitigate the risk of ship strikes are recommended as a matter of high priority. These include the placement of dedicated look-outs on fast moving vessels, the shift of ferry transects where feasible, a speed limitation for local high-risk areas where cetacean abundance is notably high, the introduction of an obligatory reporting system of vessel-whale collisions and the conduction of detailed studies dealing with this pressing issue.
