Authors: Stencel Kamil , Jureczko Mariola
Published: September 2023

This paper proposes a methodology for designing motorcycle tubular frames using simulation software such as MATLAB/Simulink and ANSYS, which provides an efficient and cost-effective way to approximate loads acting on the structure and topology optimization to meet performance and safety requirements. Using these tools, the design process can be simplified and reduce the number of costly physical prototypes and tests. The multi-body model developed in MATLAB® Simscape was used to approximate the loads and boundary conditions on the frame, while the ANSYS software was used for topology optimization. The resulting motorcycle frame was found to weigh 9.48 kg. The simulation results also showed that the proposed frame design met the required safety and performance criteria. The methodology presented in this paper is not limited to electric motorcycle tubular frames and can be applied to other types of vehicle frames or structures. The use of simulations allows for the exploration of different design options and the identification of optimal solutions with minimal cost and effort. The combination of MATLAB® Simulink and ANSYS is a powerful tool for the design and optimization of complex structures, providing accurate results and saving valuable time and resources.

Assessment of the change in the conformation and content of collagen of the goat skin due to different unhairing process
Authors: Chongeri Azaria Mikas
Published: September 2023

Recently, more attention has paid to the reduction of environmental pollution due to leather processing, the beamhouse step especially unhairing part has been named as the one which contribute high pollutants in the total industrial waste. Therefore, different types of unhairing have been studied intending to reduce waste produced by unhairing step, however, no more findings on the influence of those alternatives to the collagen of the skin which determine the features of the leather. This study explores the impacts of those unhairing alternatives to the collagen of the skin. The shrinkage temperature values were lower as compared to that of raw skin sample, where oxidative unhaired skin, shows high difference (50.50C) from raw skin sample which was 64.90C. There were no significant differences in the hydroxyproline concentration between unhairing, this was due to triple helix structure of the collagen which make it more stable and not easily destroyed by unhairing chemicals.  FT-IR results shows the differences in intensity (percentage) for side chain of collagen, where raw sample was 99.67%, oxidative was 90.83% while for conventional, hair saves and painting were 97.38%, 97.93% and 96.02% respectively. The stretching of N-H bond and bending for C-N bond for amide II, displays vibrations with wavenumber of 1519.20cm-1 for oxidative unhaired wet blue, as compared to other unhaired wet blue and raw skin sample which reads at 1539.20cm-1. The small differences in strength of the leather produced were associated with the change in the side chain intensity and conformation of collagen. The strength properties of the leather do not depend only on the concentration of the collagen but also on the proper packing of the collagen structures. The disturbance occurs to the hierarchical network of the collagen was reflected in the physical properties of the leather.
Elucidating the Effect of Genotype x Environment Interaction and Storage Period on Cooking Time of Selected Common Bean (Phaseolus vulgaris L.) Genotypes
Authors: Mvile Adriano John , Nchimbi-Msolla Susan , Muhamba Tryphone George
Published: September 2023

The cooking time of Common beans (Phaseolus vulgaris L.) is among the important consumer’s preferred traits. Slow-cooking beans lose some important micronutrients (Fe and Zn) because prolonged cooking degrades the beans at a cellular level. Fast-cooking beans save fuel energy and time which could have been spent on slow-cooking beans. Storage conditions, seed composition, cooking method, and growing environment also have an effect on the cooking time of common beans. Thirty bean genotypes with checks (Rojo and SUA-90) were laid in a Randomized Complete Block design in three environments (Ndole, Kasanga, and Mlali) in the Morogoro region. After harvesting cooking time determination was held using an automated Mattson Cooker soon after harvesting and repeated after three months (90 days). Analysis of variance revealed a significant variation (P < 0.001) among genotypes and across the environments for the first and second cooking tests. In a combined analysis, cooking time unveiled a continuous distribution ranging from 72.3-121.2 minutes for the first cooking test and 104.8-215.1 minutes for the second cooking test. Selian 10 and KT-002 recorded the shortest cooking time in the first and second cooking tests while TARI-06 and NUA-746 recorded the longest cooking time. The GGE biplot revealed SUA-90, Selian 10, NUA-672, and KT-002 were the most stable and fast-cooking genotypes in the first cooking test while NUA-746, TARI-06, and ADP-190 maintained stability but took a long time to cook. In the second cooking test, Selian 10, Uyole-04, and Selian 97 revealed high stability with a short cooking time while TARI-06 and NUA-746 revealed high stability with a long cooking time. These findings suggest that some bean genotypes can maintain the stability of fast cooking traits even after being stored for a certain time, hence these candidates can be used for breeding purposes or released as varieties.
The effects of atoxigenic A. flavus co-applied with T. asperellum on the population dynamics of toxigenic A. flavus in the soil
Authors: Tito Goodluck , Madege Richard , Mugula Jovin
Published: September 2023

Aspergillus flavus is an important aflatoxigenic fungal specie infecting crops from production to storage. Contamination of foods and their products by these mycotoxins has become a problem worldwide; in Tanzania, related deaths were reported in 2017. This study focused on assessing the effectiveness of atoxigenic Aspergillus flavus, Trichoderma asperellum and a co-inoculated atoxigenic A.flavus and T.asperellum on the population dynamic of toxigenic A.flavus in the soil. A pot experiment was set in the screen house where a known concentration of fungal inoculum was added to the sterile soil. Aspergillus spp. were isolated from soil samples by dilution plate techniques on Modified Dichloran Rose Bengal (MDRB) agar and sub-cultured on potato dextrose agar (PDA). Identification was made using morphological and microscopic characteristics of culture in PDA media. Total colony forming units (CFU g-1 of soil) and incidence percent were derived from colony count data recorded. R-statistical software version 4.0.4 was used to analyse the collected data. There was a significant difference between treatments on reducing the population (CFU/g) of toxigenic A.flavus in soil (p< 2.2×10-16). Co-inoculated T.asperellum and atoxigenic A.flavus significantly reduced the population (CFU g-1 of soil) of toxigenic A.flavus to 1.4×105 CFU g-1 of soil as compared to control treatment 4.5×105 CFU g-1 of soil. There was a strong positive correlation (p<0.001) between the incidence percent and population of toxigenic A.flavus in the soil under different biocontrol treatments. Co-inoculated T. asperellum and atoxigenic A. flavus had the lowest incidence of 36.3% to other treatments. The findings of this study demonstrate that co-inoculated atoxigenic A.flavus and T.asperellum was effective biocontrol treatment for reducing the population of Aspergillus flavus in the soil ecosystem.

Authors: Said Mohamed , Temba Augustino
Published: September 2023

An investigation of the economic viability of climate change adaptation strategies facilitates proper identification of strategies with low risk. However, there has been limited investigation of economic viability of the adopted strategies. This study aimed to examine the benefit-cost ratio of climate change adaptation strategies practiced by farmers of maize in Kongwa District, Dodoma Region. The study used a cross-sectional design to collect data. A total of 206 farmers and nine (9) key informants were involved during processes of collecting primary data. As the study adopted cross-sectional design, a questionnaire survey, key informant interview and focus group discussion were used to collect socioeconomic data, climate change adaptation strategies and cost of adaptation strategies. Qualitative data were analysed by using thematic analysis technique. Quantitative data were analyzed using descriptive statistics and econometric analysis by using benefit cost ratio. The study revealed that majority of farmers adopted several climate change adaptation strategies in order to cope with a myriad of climatic risks during maize cropping season. The most adopted strategies were intercropping (81.6%), improved seeds (63.6%), varying planting date (53.4%), tilling by tractor/power tiller (52.5%). A combination of tractor ploughing, inter-cropping, and varying plant date is the mostly (15%) adopted. All combinations of the adopted strategies were found economically viable as they revealed an average BCR of 2.1. However, the combination of tractor ploughing, intercropping, and improved seed varieties had higher BCR=2.9 when compared to other strategies. This study concludes that farmers should be advised to adopt the adaptation strategies which is economic viable with low risk, however, the strategies should be practical based on socioeconomic level of the farmers and environmental conditions.

MSK significantly improved clinical symptoms, hemodynamic parameters and stopped bleeding in PPH patients, timely application of MSK can significantly prevent PPH maternal death and PPH rehospitalization.
Open Science and Policy Interface: The Tanzania Perspective
Authors: Muneja Paul
Published: September 2023

The 21st century has seen a paradigm shift in scholarly communication, with digital technology changing the entire process of the scholarly communication lifecycle. As the cost of online reference materials for research continues to rise and restrictive conditions persist, global academic and research communities are pursuing countermeasures to make knowledge equitable and accessible. This is made possible through the Open Science (OS) movement that aims to make knowledge accessible to researchers and citizens irrespective of their technical or financial capability. This paper explores open science to ascertain the status of open science practices in Tanzania. The paper highlights the policy interfaces and frameworks that favor open science practices in research endeavors. Also, it provides a baseline for understanding the situation to inform scientific research and education communities about the status of open science and possible areas of intervention. Open science is still in its infancy, although certain steps have been taken in adopting it for example the adoption of open access practices, including the creation of institutional repositories and the adoption of policies that direct its implementation. Additionally, the implementation of open data practices has been quite slow. Also, researchers and organizations in Tanzania are gradually adopting open data practices. Currently, some academic institutions, particularly public universities, have adopted and used open journal publishing systems, particularly the online journal system (OJS). The published journal articles through journal systems are freely accessible online like other open-access content, however, the journals are not yet registered in the Directory of Open Access Journals (DOAJ) despite the fact that some are already indexed in different abstracting services such as Africa Journal Online (AJOL) and they have Digital Object Identifiers (DOI). The policy interface of open science needs to be harmonized and COSTECH is strategically positioned to take the lead.

Perceived Femininity: Women Working in Male-Dominated Occupations
Authors: Bima Nadia Revania , Primadini Intan
Published: September 2023

Patriarchal society significantly affects how people interpret gender In the Indonesian, which leads to segregation and gender stereotypes in the workplace.Current development, women are entering fields like mining and construction that were formerly dominated by men. This study seeks to understand how women perceive their femininity when working in environments where men predominate. The research method is interpretive phenomenological analysis (IPA), which uses a qualitative and explorative approach in line with the constructivist paradigm. The information gathered from interviews was analyzed using Smith, Flowers, and Larkin's (2009) data analysis techniques. The findings indicate that women who work in professions where men predominate regard their femininity as a combination of traditional femininity, new femininity, and adopted male traits as a means of adjusting to the workplace. This leads us to the conclusion that femininity is currently changing and that women today tend to express themselves more freely.
Multidimensional Radiation Hydrodynamics Simulations of Pulsational Pair-instability Supernovae
Authors: Chen Ke-Jung , Whalen Daniel J. , Woosley S. E. , Zhang Weiqun
Published: September 2023

Stars with masses of 80–130 M
⊙ can encounter pulsational pair-instability at the end of their lives, which triggers consecutive episodes of explosive burning that eject multiple massive shells. Collisions between these shells produce bright transients known as pulsational pair-instability supernovae (PPI SNe) that may explain some extreme supernovae. In this paper, we present the first 2D and 3D radiation hydrodynamics simulations of PPI SNe with the CASTRO code. Radiative cooling causes the collided shells to evolve into thin, dense structures with hot spots that can enhance the peak luminosity of the SN by factors of 2–3. The light curve peaks at 1.9–2.1 × 1043 erg s−1 for 50 days and then plateaus at 2–3 × 1042 erg s−1 for 200 days, depending on the viewing angle. The presence of 12C and 16O and the absence of 28Si and 56Fe in its spectra can uniquely identify this transient as a PPI SN in follow-up observations. Our models suggest that multidimensional radiation hydrodynamics is required to model the evolution and light curves of all shell-collision SNe, such as Type IIne, not just PPI SNe.

We demonstrate how to fine-tune the filter to meet observational constraints and focus on specific wave-front speeds. This refinement enables discrimination of acoustic source depths and tracking of local source wave fronts, thereby facilitating ultralocal helioseismology. By utilizing the photospheric Doppler signal from a subsurface source in a MURaM simulation, we demonstrate that robust ultralocal three-dimensional helioseismic inversions for the granular flows and the local sound speed to depths of at least 80 km below the photosphere are possible. The capabilities of the National Science Foundation’s new Daniel K. Inouye Solar Telescope will enable such measurements of the real Sun.

Soil nematodes are one of the most important terrestrial faunal groups in Antarctica, as they are a major component of soil micro-food webs. Despite their crucial role in soil processes, knowledge of their species diversity and distribution is still incomplete. Taxonomic studies of Antarctic nematodes are fragmented, which prevents assessment of the degree of endemicity and distribution of the species, as well as other aspects of biogeography.

The present study is focused on the nematode fauna of one of the three Antarctic sub-regions, the Maritime Antarctic and summarises all findings published up to April 2023. A species list that includes 44 species, belonging to 21 genera, 16 families and eight orders is provided. A review of the literature on terrestrial nematodes inhabiting the Maritime Antarctic showed that the sites are unevenly studied. Three islands (Signy, King George and Livingston Islands) revealed highest species richness, probably due to the highest rates of research effort. Most species and four genera (Antarctenchus, Pararhyssocolpus, Amblydorylaimus and Enchodeloides) are endemic, proving that nematode fauna of the Maritime Antarctic is autochthonous and unique. Several groups of islands/sites have been revealed, based on their nematode fauna. The study showed that species with a limited distribution prevailed, while only two species (Plectus antarcticus and Coomansus gerlachei) have been found in more than 50% of the sites. Based on the literature data, details on species localities, microhabitat distribution, plant associations and availability of DNA sequences are provided.

The species inventory of global biodiversity is constantly revised and refined by taxonomic research, through the addition of newly discovered species and the reclassification of known species. This almost three-century-old project provides essential knowledge for humankind. In particular, knowledge of biodiversity establishes a foundation for developing appropriate conservation strategies. An accurate global inventory of species relies on the study of millions of specimens housed all around the world in natural history collections. For the last two decades, biological taxonomy has generated an increasing amount of data every year, and notably through the digitization of collection specimens, has gradually been transformed into a big data science. In recognition of this trend, the French National Museum of Natural History has embarked on a major research and engineering challenge within its information system: the adoption of cyber-taxonomic practices that require easy access to data on specimens housed in natural history collections all over the world. To this end, an important step is to automatically complete and reconcile the heterogeneous classification data usually associated with specimens managed in different collection databases. We describe here a new fuzzy approach to reconciling the classifications in multiple databases, enabling more accurate taxonomic retrieval of specimen data across databases.

In recent years, deep learning methods in the biodiversity domain have gained significant attention due to their ability to handle the complexity of biological data and to make processing of large volumes of data feasible. However, these methods are not easy to interpret, so the opacity of new scientific research and discoveries makes them somewhat untrustworthy. Reproducibility is a fundamental aspect of scientific research, which enables validation and advancement of methods and results. If results obtained with the help of deep learning methods were reproducible, this would increase their trustworthiness. In this study, we investigate the state of reproducibility of deep learning methods in biodiversity research.

We propose a pipeline to investigate the reproducibility of deep learning methods in the biodiversity domain. In our preliminary work, we systematically mined the existing literature from Google Scholar to identify publications that employ deep-learning techniques for biodiversity research. By carefully curating a dataset of relevant publications, we extracted reproducibility-related variables for 61 publications using a manual approach, such as the availability of datasets and code that serve as fundamental criteria for reproducibility assessment. Moreover, we extended our analysis to include advanced reproducibility variables, such as the specific deep learning methods, models, hyperparameters, etc., employed in the studies.

To facilitate the automatic extraction of information from publications, we plan to leverage the capabilities of large language models (LLMs). By using the latest natural language processing (NLP) techniques, we aim to identify and extract relevant information pertaining to the reproducibility of deep learning methods in the biodiversity domain. This study seeks to contribute to the establishment of robust and reliable research practices. The findings will not only aid in validating existing methods but also guide the development of future approaches, ultimately fostering transparency and trust in the application of deep learning techniques in biodiversity research.
Leveraging AI in Biodiversity Informatics: Ethics, privacy, and broader impacts
Authors: Lewers Kristen "Kit"
Published: September 2023

Artificial Intelligence (AI) has been heralded as a hero by some and rejected as a harbinger of destruction by others. While many in the community are excited about the functionality and promise AI brings to the field of biodiversity informatics, others have reservations regarding its widespread use. This talk will specifically address Large Language Models (LLMs) highlighting both the pros and cons of using LLMs. Like any tool, LLMs are neither good nor bad in and of themselves, but AI does need to be used within the appropriate scope of its ability and properly. Topics to be covered include model opacity (Franzoni 2023), privacy concerns (Wu et al. 2023), potential for algorithmic harm (Marjanovic et al. 2021) and model bias (Wang et al. 2020) in the context of generative AI along with how these topics differ from similar concerns when using traditional ML (Machine Learning) applications. Potential for implementation and training to ensure the most fair environment when leveraging AI and keeping FAIR (Findability, Accessibility, Interoperability, and Reproducibility) principles in mind, will also be discussed.

The topics covered will be mainly framed through the Biodiversity Information Standards (TDWG) community, focusing on sociotechnical aspects and implications of implementing LLMs and generative AI.

Finally, this talk will explore the potential applicability of TDWG standards pertaining to uniform prompting vocabulary when using generative AI and employing it as a tool for biodiversity informatics.
Induction of Posterior Vitreous Detachment Using Perfluorooctane Dissection in a Pediatric Patient
Authors: Hoyek Sandra , Wu Frances , Berrocal Audina M. , Patel Nimesh A.
Published: September 2023

Background and Objective:

Inducing a posterior vitreous detachment (PVD) may be challenging, especially in pediatric patients with firm vitreo-retinal adherence. This case report will present an alternative method of PVD induction using adjunctive perfluorooctane (PFO).

Materials and Methods:

An 11-year-old boy underwent scleral buckle placement and 23-gauge pars plana vitrectomy for macula-off retinal detachment. Triamcinolone acetonide was used for vitreous staining. A flexible loop was used to peel the hyaloid membrane from attached retina nasal to the optic nerve. A small hole was created in the posterior hyaloid, and a small PFO bubble was injected under the detached vitreous to further dissect it from the retina and propagate the vitreous detachment anteriorly. The vitrector was used to lift and complete the PVD peripherally.

Results:

PVD induction was obtained with no iatrogenic retinal breaks or postoperative complications.

Conclusion:

PVD induction using a stepwise PFO approach is a safe and effective alternative to conventional techniques.

Published: September 2023

Photodynamic acute exudative maculopathy is a transient increase in subretinal fluid (SRF) within the first days after treatment in different chorioretinal diseases and tumors. Recently, this entity has attracted much attention. However, no cases of acute exudative maculopathy have been described after subthreshold laser (STL). This report presents the case of a 35-year-old male with chronic central serous chorioretinopathy with an extrafoveal serous retinal pigment epithelium detachment (PED) who underwent STL. One day after treatment, the patient noted an acute decrease in visual acuity and abundant SRF. One month after treatment, both the SRF and PED were spontaneously resolved.

Published: September 2023

In this work, a novel method for a more sustainable recycling and cost-efficient manufacturing technique of polyether ketone ketone (PEKK) based thermoplastic composite materials is proposed to recover and reprocess waste and end-of-life materials in the aerospace industry. For the recycling of carbon fiber reinforced thermoplastics (CFrTP), an innovative scrapping process based on mechanical cutting was developed and the properties of the obtained scrap and the recycled panel were analyzed. Thus, a cutting tool was developed for the delamination of the input material so that long fibers can be retained in the resulting scrap. Different processing approaches of material scrapping were evaluated, aiming to obtain manageable scrap that can be subsequently used for a compression molding process. Additionally, an automatic process was evaluated to manage the scrap and perform the corresponding lay-up to manufacture high-quality thermoplastic composite products with recycled materials.
