Authors: Badamasi Afusat Ejide
Published: April 2024

This study examined how secondary school students in Abuja, the Federal Capital Territory, perceived gender differences in social vices. The study used a mixed approach method. A sample of 300 respondents were drawn from both the senior and junior secondary school levels, and the population were all students attending secondary schools in the Federal Capital Territory of Abuja. Fifty respondents were chosen from each of the six secondary schools from which samples were drawn; however, ten individuals failed to return their questionnaires. The study’s schools and participants were chosen using simple stratified random sampling procedures. To gather data on social vices in secondary schools, a self-designed instrument was employed. A significance threshold of 0.05 was used to assess two hypotheses and three research questions. To address the research question, t-test statistics were employed, and two hypotheses were tested using mean, standard deviation, t-value, and p-value. The findings showed that students’ perceptions of social vices were comparable throughout the Federal Capital Territory, Abuja. Also, it demonstrated that while gender had no discernible impact on the social vices’ students committed, males were more likely than females to participate in certain categories of social vices. Additionally, the results showed that male students had a higher propensity than female students for aggressive social vices. To help students learn how to behave properly in and out of the classroom, it has recommended among other things that school administrators and other educational stakeholders organize seminars and workshops on the risk of social vices. Additionally, parents should be educated on how to properly care for and raise their children and dependents.

Published: April 2024

The foundry is an industrial sector where various iron, scrap steel, and ferroalloys are melted down in arc furnaces or cupolas, shaped in sand, ceramic, or metal moulds, and the cast, steel, nodular, and tempered foundry products needed in industry are produced as raw or processed materials. Especially in establishments such as factories and workshops that produce parts of the automotive, construction, and machine and in steel industry, foundry sand is used to mould foundry products (iron-steel industry and aluminium- and copper-based alloys).Foundry sand is used to prepare metal foundry moulds. For 1 ton of production, 4-5 tons of sand is required. This ratio may be changed based on the type of the metal that needs to be casted, part size, and moulding technique. Sands that contain more than 90% of silica and 7–15% clay (bentonite or kaolinite clay) and have a sintering temperature of over 1500°C are defined as foundry sands. Foundry sand disposal is a herculean task for the industrial sector in today’s scenario. In order to overcome this problem to some extent, it is required to convert it into some useful products. Hence, this project gains its importance for the effective utilization of foundry sand into foundry sand bricks

Published: April 2024

Customer opinions play a vital role in buying decisions. These days most customers post their opinions about products on blogs, e-commerce sites, review sites, and social networking sites. The above information is consumed by business or corporate organizations, as they are eagerly interested in analyzing consumer views about their products, services, and support. As people buy products after reading the reviews, the kind of reviews that a product attracts are of concern to the sellers. This means that a positive review on the product would bring in sales and a negative one would reduce them. The project leverages Natural Language Processing (NLP) techniques and supervised learning algorithms to build a robust spam review detection system. The system is trained on a dataset comprising genuine and spam reviews, and it extracts various features from the textual content of reviews, such as sentiment analysis, linguistic patterns, and semantic meaning.

Einsatzgebiete für Nanofasern
Authors: Schneiders Thomas
Published: April 2024

Nanofasern und ultrafeine Fasern (Durchmesser >1 µm) in textiler Form eines Vliesstoffs oder Garns weisen sehr gute Eigenschaften für Anwendungen wie Tissue Engineering, medizinische Produkte mit Wirkstofffreisetzung, Filtration, Katalyse, aber auch technische Textilien und Schutzkleidung auf. Zu diesen Eigenschaften gehören eine hohe spezifische Oberfläche, eine verbundene Porenstruktur und einstell­bare Porengrößen. Für die Herstellung von Fasern mit einem Durchmesser von weniger als einem Mikrometer werden verschiedene Technologien wie das Melt Blowing, Bikomponentenspinnverfahren, Zentrifugalspinnen oder Elektrospinnen verwendet. Die meisten Verfahren sind entweder mit hohen Investitions- und Betriebskosten verbunden und auf wenige Polymere oder Materialkombinationen beschränkt oder sie erzeugen breit gestreute und ungleichmäßige Faserdurchmesser. Das Elektrospinnen aus Polymerlösungen ist aufgrund seiner Einfachheit und Kosteneffizienz sowie der hohen Materialkompatibilität die praktikabelste Methode zur Herstellung von Nanofasern.1,2

The experiment was carried out to evaluate the effect of replacing corn with three dietary fibre sources on the growth performance and carcass quality of broiler chicken. One hundred and forty four one-day old broiler chickens were used for the experiment. The birds were brooded for two weeks on commercial starter diet after which they were subjected to four experimental diets or treatments. The birds were randomly distributed into four treatments with three replicates, each replicate consisting of 12 birds. All birds in each treatment were fed with different diet and weighed at the end of every week. The experimental design used was a completely randomized design. The experimental treatments were designated as treatment T1, T2, T3, T4 while T1 was tagged as a control diet without any source of dietary fibre, T2 as a diet with wheat bran as a source of dietary fibre, T3 as a diet with rice bran as a source of dietary fibre, T4 as a diet with brewers dried grain (BDG) as a source of dietary fibre. There was no significant (p>0.05) difference in the initial weight of the birds across the treatments, but there was a significant (p<0.05) difference in the final weight and body weight gain of the birds where T2 had the highest body weight gain and T3 has the lowest body weight gain. This trend was also observed in the carcass. Based on the result of this experiment wheat bran can be used as a source of dietary fibre for better growth performance of broiler chicken at a low inclusion level.

Authors: Ong Kai Ping , Yeoh Zhi Xiang , Khoo Jing Hern , Sheikh Ab Hamid Suzina , Gazali Norzi
Published: April 2024

Objective: The study aims to review the clinical outcomes of supraglottoplasty in moderate and severe laryngomalacia. Methods: This is a retrospective study. Demographic and clinical data of children diagnosed with moderate and severe laryngomalacia who underwent supraglottoplasty between 2012 and 2021 were retrieved from the computerized patient record system of Hospital Sultanah Bahiyah. The surgical procedure of supraglottoplasty was mainly performed with cold instrument, with occasional assistance from a microdebrider. Study outcome includes complete stridor resolution, weaning from tube feeding, and weaning from respiratory support post supraglottoplasty. Results: 124 children were included in the study. Complete stridor resolution was achieved in 64.51% (n=80) 1-month post-surgery and 86.29% (n=107) 3-months post-surgery. Half of the children with tube feeding pre-operatively could be weaned off to oral feeding within 1-month post-surgery. All the children with oral feeding maintained oral feeding post-surgery. All the children with no or low respiratory support (nasal prong oxygen) pre-operatively were able to be weaned down to room air within 1-month post-surgery. Within the group of children with high respiratory support (high-flow nasal cannula, non-invasive ventilation, and endotracheal intubation) pre-operatively, half were weaned down to room air within 1-month post-surgery. None of the children with isolated laryngomalacia required tracheostomy after supraglottoplasty. All laryngomalacia patients who required tracheostomy after supraglottoplasty were associated with either synchronous airway lesions or medical comorbidities. Only 3 cases (2.42%) required revision supraglottoplasty with a maximum of one revision. Conclusions: We conclude that supraglottoplasty contributes to substantial clinical improvement in moderate and severe laryngomalacia. Supraglottoplasty facilitated weaning down of respiratory support and tube feeding in laryngomalacia with respiratory difficulty and feeding intolerance.

Spring 2021 sea ice transport in the southern Beaufort Sea occurred during coastal ice opening events
Authors: Jewell MacKenzie E. , Hutchings Jennifer K. , Bliss Angela C.
Published: April 2024

Abstract. Winds blew a record large portion of the Arctic’s multiyear sea ice (MYI) into the southern Beaufort Sea (SBS) in winter 2021. From early March, a network of buoys from the Sea Ice Dynamic Experiment (SIDEx) tracked the MYI as it drifted across the SBS toward the Chukchi Sea. Transport was episodic as the consolidated ice pack interacted with coastal boundaries and repeatedly fractured. We investigated variability in 2021 MYI transport by relating in situ sea ice drift to remotely sensed coastal lead opening events, which have been shown to increase ice drift speeds in winter. Daily ice concentration data show ten opening events occurred throughout March and April 2021. Opening lasted 1–5 days as southeasterly winds pushed the SBS ice pack away from local coastal boundaries. During opening, the ice pack abruptly accelerated and its response to wind forcing stabilized around free drift conditions, drifting at 2.1 % of wind speeds (median rate of 14 km d−1). With this efficient wind-to-ice momentum transfer, nearly all (94 %) SBS MYI transport in March–April 2021 occurred during opening events, despite spanning just half the time. Only 6 % of transport occurred during the other half of days without opening. On these days, the ice was mostly stationary (median 2 km d−1 drift rate, 0.6 % of wind speeds) as northwesterly winds compressed the pack against the coast. Spatiotemporal discontinuities in ice-wind speed ratios were measured across several coastal leads that transected the SIDEx buoy network, providing direct observations of ice drift modulation by coastal lead formation. These results quantify the disproportionate contribution of coastal lead opening events to SBS ice transport during spring 2021, highlighting the critical role these transient events play in patterns of sea ice drift at seasonal timescales.

Abstract. In recent years citizen science emerged as a promising technology in environmental science and hydrology with the potential to overcome the lack of in-situ measurements and create efficient ecosystems. This paper provides an up-to-date systematic literature review of applications of citizen science technology in water quality monitoring and estimation. A bridge between citizen science and remote sensing will be established to provide a sound framework for comprehensively discussing the various approaches and applications. A scrutinizing of various water quality parameters and associated measurement and estimation methods is provided, delving into various remote sensing systems (microwave and optical systems) and imaging techniques (hyperspectral and hyperspectral methods). A special interest is focused on reviewing existing relevant crowd-sourcing mobile apps such as EyeOnWater, HydroColor, EnviObserver, Sechhi App, Hydro Crowd, and SIMILE-Lake monitoring, detailing their working mechanisms, algorithms, data acquisition processes, used sensors, and measured water quality parameters. Finally, the paper summarizes key knowledge gaps, challenges and promising directions in this research field.

Abstract. This study proposes the use of a data-driven statistical model to freeze the errors due to differences in environmental forcing when evaluating the surface turbulent heat fluxes from weather and climate numerical models with the observations. It takes advantage of continuous acquisition over approximately ten years of near-surface sensible and latent heat fluxes (H and LE respectively) together with ancillary parameters over the supersite "Météopole" of the French national research infrastructure ACTRIS-FR, located in Toulouse. The statistical model consists of several multi-layer perceptrons (MLPs) with the same architecture. Thirteen variables characterizing the environmental forcing in the surface layer at an hourly time scale are used as input parameters to estimate H and LE simultaneously. The MLPs are trained using 5-year observational data under a 5-fold cross-validation. The remaining data is used to test the estimates on unknown conditions. A case study is performed with data from a regional climate simulation. The performance of the statistical model ranges within the state-of-the-art surface parametrization schemes on hourly and seasonal time scales. It has also a good generalization ability, but hardly estimates negative H and large LE. The statistical model is used to evaluate the simulated fluxes under the simulated environment to better examine the flaws of their numerical formulation throughout the simulation. Comparison of simulated fluxes with observed and MLP-based fluxes show different results. According to MLP-based fluxes in the simulated environment, the land surface scheme of this climate model tends to underestimate large sensible heat flux. Thus, it incorrectly partitions between surface heating and evaporation during the late summer. Our innovative method provides insight into differently evaluating the simulated near-surface turbulent heat fluxes when a long period of comprehensive observations is available. It can usefully support ongoing efforts for improvements of surface parametrization schemes.
Size scaling of large landslides from incomplete inventories

Abstract. Landslide inventories have become cornerstones for estimating the relationship between the frequency and size of slope failures, thus informing appraisals of hillslope stability, erosion, and commensurate hazard. Numerous studies have reported how larger landslides are systematically rarer than smaller ones, drawing on probability distributions fitted to mapped landslide areas or volumes. In these models, much uncertainty concerns the larger landslides (defined here as affecting areas ≥ 0.1 km2) that are rarely sampled, and often projected by extrapolating beyond the observed size range in a given study area. Relying instead on size-scaling estimates from other inventories is problematic because landslide detection and mapping, data quality, resolution, sample size, model choice, and fitting method can vary. To overcome these constraints, we use a Bayesian multi-level model with a Generalised Pareto likelihood to provide a single, objective, and consistent comparison grounded in extreme-value theory. We explore whether and how scaling parameters vary between 37 inventories that, although incomplete, bring together 8627 large landslides. Despite the broad range of mapping protocols and lengths of record, and differing topographic, geological, and climatic settings, the posterior power-law exponents remain indistinguishable between most inventories. Likewise, the size statistics fail to separate known earthquake from rainfall triggers, and event-based from multi-temporal catalogues. Instead, our model identifies several inventories with outlier scaling statistics that reflect intentional censoring during mapping. Our results thus caution against a universal or solely mechanistic interpretation of the scaling parameters, at least in the context of large landslides.
How heating tracers drive self-lofting long-lived stratospheric anticyclones: simple dynamical models
Authors: Shah Kasturi , Haynes Peter H.
Published: April 2024

Abstract. Long-lived “bubbles” of wildfire smoke or volcanic aerosol have recently been observed in the stratosphere, co-located with ozone, carbon monoxide, and water vapour anomalies. These bubbles often survive for several weeks, during which time they ascend through vertical distances of 15 km or more. Meteorological analysis data suggest that this aerosol is contained within strong, persistent anticyclonic vortices. Absorption of solar radiation by the aerosol is hypothesised to drive the ascent of the bubbles, but the dynamics of how this heating gives rise to a single-sign anticyclonic vorticity anomaly have thus far been unclear. We present a description of heating-driven stratospheric vortices, based on an axisymmetric balanced model. The simplest version of this model includes a specified localised heating moving upwards at fixed velocity and produces a steadily translating solution with a single-signed anticyclonic vortex co-located with the heating, with corresponding temperature anomalies forming a vertical dipole, matching observations. A more complex version includes the two-way interaction between a heating tracer, representing the aerosol, and the dynamics. An evolving tracer provides heating which drives a secondary circulation, and this in turn transports the tracer. Through this two-way interaction an initial distribution of tracer drives a circulation and forms a self-lofting tracer-filled anticyclonic vortex. Scaling arguments show that upward velocity is proportional to heating magnitude, but the magnitude of peak quasigeostrophic vorticity is O(f) (f is the Coriolis parameter) and independent of the heating magnitude. Estimates of vorticity from observations match our theoretical predictions. We discuss 3-D effects such as vortex stripping and dispersion of tracer outside the vortex by the large-scale flow, which cannot be captured explicitly by the axisymmetric model and are likely to be important in the real atmosphere. The large O(f) vorticity of the fully developed anticyclones explains their observed persistence and their effective confinement of tracers. To further investigate the early stages of formation of tracer-filled vortices, we consider an idealised configuration of a homogeneous tracer layer. A linearised calculation reveals that the upper part of the layer is destabilised due to the decrease in tracer concentrations with height there, which sets up a self-reinforcing effect where upward lofting of tracer results in stronger heating and hence stronger lofting. Small amplitude disturbances form isolated tracer plumes that ascend out of the initial layer, indicative of a self-organisation of the flow. The relevance of these idealised models to formation and persistence of tracer-filled vortices in the real atmosphere is discussed, and it is suggested that a key factor in their formation is the time taken to reach the fully developed stage, which is shorter for strong heating rates.

Abstract. Floating offshore wind is widely considered to be a promising technology to harvest renewable energy in deep ocean waters and increase clean energy generation offshore. While evolving quickly from a technological point of view, floating offshore wind turbines (FOWTs) are challenging, as their performance and loads are governed by complex dynamics that are a result of the coupled influence of wind, waves, and currents on the structures. Many open challenges therefore still exist, especially from a modeling perspective. This study contributes to the understanding of the impact of modeling differences on FOWT loads by comparing three FOWT simulation codes, QBlade-Ocean, OpenFAST, and DeepLines Wind®, and three substructure designs, a semi-submersible, a spar buoy, and the two-part concept Hexafloat, in realistic environmental conditions. This extensive comparison represents one of the main outcomes of the Horizon 2020 project FLOATECH. In accordance with international standards for FOWT certification, multiple design situations are compared, including operation in normal power production and parked conditions. Results show that the compared codes agree well in the prediction of the system dynamics, regardless of the fidelity of the underlying modeling theories. However, some differences between the codes emerged in the analysis of fatigue loads, where, contrary to extreme loads, specific trends can be noted. With respect to QBlade-Ocean, OpenFAST was found to overestimate lifetime damage equivalent loads by up to 14 %. DeepLines Wind®, on the other hand, underestimated lifetime fatigue loads by up to 13.5 %. However, regardless of the model and FOWT design, differences in fatigue loads are larger for tower base loads than for blade root loads due to the larger influence substructure dynamics have on these loads.
