Authors: Yin Wenwen
Published: December 2024

With the continuous deepening of vocational education reforms, vocal music teaching, as an important part of art education in vocational colleges, faces numerous challenges, such as traditional teaching models and the inability to meet students' individual needs. The traditional teaching model has limitations in cultivating students' practical abilities and professional qualities, and it is difficult to meet the demand for high-quality, comprehensive artistic talents in modern society. Based on the analysis of the current situation of vocal music teaching in vocational colleges, this paper proposes an innovative teaching model oriented toward student subjectivity, centered on project-based practice, with an emphasis on informatization and cross-cultural innovation. The paper explores the implementation path of teaching model innovation. Additionally, it discusses specific measures to ensure the effective implementation of the innovative teaching model from the perspectives of optimizing faculty, building teaching resources, and improving the evaluation system. The research aims to provide theoretical support and practical guidance for vocal music teaching in vocational colleges and promote the high-quality development of vocational art education.
Study of Spin-Wave Mode Coupling and Band Structure in Magnetostatic Crystal
Authors: Hu Xiaoying
Published: December 2024

Magnetostatic crystals are magnetic materials with a periodic structure, and the coupling of their spin-wave modes and band structure has a significant impact on their dynamic behavior and applications. This paper investigates the spin-wave mode coupling mechanism, the evolution of the band structure, and the regulation methods within magnetostatic crystals. It explores their potential applications in fields such as spintronics and quantum computing. The study shows that the coupling of spin waves depends not only on exchange interactions but is also influenced by magnetic anisotropy, nonlinear effects, and external fields. The coupling of spin-wave modes can lead to the reconstruction of the band structure, affecting the propagation characteristics and stability of spin waves. Methods for regulating the band structure, such as external magnetic field adjustments, crystal geometric design, and nonlinear coupling, provide new pathways for optimizing spin-wave propagation characteristics. These studies offer theoretical support and a technical foundation for fields such as quantum information processing, low-power spin-wave communication, and spin current control.

Published: December 2024

The era of Education 4.0 is education characterized by the use of digital technology in the learning process. The teaching and learning process that is integrated with appropriate technology will support the success of education in this era. Vocational education is a tertiary institution that supports the mastery of applied skills in certain fields. Shipping is one of these vocational fields. Shipping is closely related to the port and the loading and unloading process in it. Generally, this loading and unloading process takes quite a long time and causes congestion. The reason is that it is difficult to find an instant way to arrange items that are easy to pick up in the order they arrive. The purpose of this study is to develop a web-based simulator to determine the right stowage plan for the arrangement of containers on a transport ship and implement it in learning in shipping vocational education (Polteknik Pelayaran Surabaya and Politeknik Pelayaran Malahayati). With the RnD type, this research produces a simulator design that can display ship mileage, ship data, container data, container arrangement on ships, as well as ship stability and displacement calculations. It is hoped that with this simulator, the loading and unloading process at the port will be faster and congestion can be reduced. When implemented in Cargo Handling and Stowage Include Cargo Space and Reporting classes and ship construction and stability, the simulator media had a positive effect on cadets (87% through the results of the response questionnaire and 86.5% on competency tests).

Fuel oil is a primary need for the community to assist mobility activities in daily life. The role of fuel oil until now is an energy source that has become the main choice for use in various sectors, especially in shipping, it is a must as a transportation operator to monitor the availability of fuel oil on ships so that shipping traffic runs smoothly between lands. With the rapid development of technology in the current era of globalization, it has provided many benefits in progress in various aspects. The use of technology by humans in helping to complete work is a must in life. The development of this technology must also be followed by developments in Human Resources (HR). Humans as technology users must be able to take advantage of current technology, as well as subsequent technological developments. Human adaptation to new technologies that have developed must be done through innovation. The Time of Flight sensor is an electronic component that functions to measure the distance between the sensor and the object. In this study, use this for the purposes of measuring the level of the fuel tank on the ship. Thus, it can determine the level of the fuel level in the tank so that there is no oil spill, so that it can be monitored using Arduino.

Published: December 2024

The issue of climate change due to the greenhouse effect encourages various parties to try reducing emissions in energy fulfilment. In maritime sector, IMO has adopted mandatory measures to reduce emissions of greenhouse gases (GHG) from international shipping, under IMO's pollution prevention treaty (MARPOL). Besides Carbon Oxides (COX), statistics show that other exhaust emissions from ships, such as Sulfur Oxides(SOX), Nitrogen Oxides(NOX) and Particulate Matters(PM) have also increased significantly in the past years due to the rapid increase of the maritime transportation. It is necessary for the shipping industries to find out the available clear energy to reduce the emission of GHG. This paper will discuss application of solar and wind energy on ship power systems, current status and future prospect.

The current world condition has changed quite significantly, the impact of black swans that occurred due to the COVID-19 pandemic contributed quite a lot to the Industrial Revolution 5.0 accompanied by the era of society 5.0  where humans work hand in hand with robots and everything is automation and digitization. This also has an impact on the shipping industry, including commercial ships, where currently individuals who have competence in the field of electrical systems are needed to keep mobilization and business in the maritime industry going on. Through the Standards of Training and Watchkeeping (STCW) all ships sailing currently have the obligation to assign individuals responsible for the electrical system on board the ship, namely the Electro Technical Officer (ETO). Given the high demand and level of urgency by various companies both domestically and abroad for ETO graduates, the Surabaya Shipping Polytechnic decided to open a Diploma III Study Program in Electrical Sailing, and obtained the first graduates in 2016.  Based on the results of the analysis, it can be concluded that in Strategy and Operations Management, Politeknik Pelayaran Surabaya has made efforts to improve  the quality of education for ETOp graduates, this is reflected in the proportion of budget allocations issued annually, the provision of adequate facilities and infrastructure, the evaluation of the performance and quality of teaching lecturers and educators on a regular basis, the preparation of curriculum and implementation in  the form of textbooks and the interaction of teaching patterns with students as well as the existence of quality assurance. This success is reflected by the high absorption of ETO graduates at the Surabaya shipping polytechnic every year where most ETO graduates have been accepted for work within 1-3 months after graduation

Published: December 2024

Ubaldo Mastromatteo published in 2016, a very simple experiment where he directed a laser beam on a thin film of palladium deposited on a silicon oxide substrate in H2 and D2 atmospheres. By SEM he showed formation of many new elements. In this study, we made a similar experiment with identical samples in H2 and D2. Both experiments lasted 3 months. The laser used was a 5 mW 650 nm red pointer laser. What surprised us is that in a particular 180 μm diameter spot, many new elements appeared that were not there before, and in some parts of the spot the palladium had totally disappeared. The experiments were analyzed by SEM and neutrons were potentially observed with CR-39.
Energetic Ion Emission from TiDx in Low-Energy Ion Beam Experiments
Authors: Forbes Sadie , Hagelstein Peter L. , Metzler Florian
Published: December 2024

Low-level energetic ion emission has been reported previously in many low-energy nuclear reactions (LENR) experiments including electrolysis, gas-loading and ion beam experiments. The corresponding reports present evidence for MeV-level charged ions and neutrons associated with deuterium-deuterium fusion reactions, and also particles at higher energy that would be expected to originate from other processes. A study of low-level energetic nuclear particles has the potential to shed light on nuclear processes relevant to excess heat production and other LENR anomalies, which provides motivation to focus on such observables. In some of the referenced earlier experiments a small number of very energetic charged particle emissions near 20 MeV have been reported, which is of particular interest to us in connection with the involved mechanisms. We developed an ion beam experiment in which thick (1.59 mm) and thin (5 μm) Ti foils were initially loaded with deuterium by ion beam implantation and then bombarded with argon ions at 950 eV. A small number of counts in high-energy detector channels were recorded in eight different experiments, corresponding to particle energies estimated to be between 32-40 MeV, based on a calibration at lower energies with an 241Am calibration source. Experiments with the 5 μm Ti foil also resulted in dozens of counts below about 11 MeV.
Direct Electricity Production from NANOR®-type ZrO2-PdNiD Components Using Ultrasound
Authors: Swartz Mitchell
Published: December 2024

This paper describes new features of the NANOR®-type CF/LANR component technology. We report direct production of “excess electricity”; ⇠655% higher than anything seen of any control. Thus, deuterated NANOR®-type components now appear to offer two methods of energy production. Direct LANR electric output may eventually bypass the need for thermoelectric energy conversion handicapped by Carnot inefficiency.

Published: December 2024

The depletion of conventional energy resources necessitates the exploration of alternative energy sources, such as solar, wind, geothermal, and bio-gas. However, these renewable options have limitations in different climatic conditions and require large land areas for installation, while their output efficiency remains comparatively low. To address this challenge, the study of Low Energy Nuclear Reactions (LENR) presents a promising avenue for green, clean, portable, and sustainable energy. The Centre for Energy Research (CER) at S-VYASA University, Bangalore, India, has actively pursued LENR research for the past 9 years. Research groups have observed that the absorption of hydrogen into metal lattices is a crucial condition for LENR to occur. Various research groups, including CER, have explored metals like nickel, platinum, titanium, and palladium for high levels of hydrogen loading at controlled temperatures and pressures. In this study, two identical reactors were fabricated, one with an active fuel component and the other serving as a control unit. Both reactors underwent identical processes and hydrogen loading protocols. The active reactor consistently exhibited higher skin temperatures compared to the control reactor under the same power input, indicating the generation of excess heat. The experiment ran continuously for three months, showcasing sustained excess temperatures.
Very Sizeable Increase of Gravitation at Picometer Distance: A Novel Working Hypothesis to Explain Anomalous Heat Effects and Apparent Transmutations in Certain Metal/Hydrogen Systems
Authors: Dufour J.
Published: December 2024

Since more than 15 years, unexplained heat effects have been reported in systems involving hydrogen isotopes (hydrogen and deuterium) and certain metals like palladium. The most studied system (palladium/deuterium) has given birth to the “Cold Fusion” concept: a special kind of DD fusion reaction, only occurring in a metallic lattice, which yields heat and helium-4 as the main reaction product. Other systems have also been studied (nickel hydrogen and caesium/deuterium for instance), showing shifts in isotopic ratio of the products of reaction and leading to the more generalized concept of Low Energy Nuclear Reaction (LENR). A novel conjecture (the pico-gravity conjecture) is presented here, that may explain all the anomalies observed in this so-called “Cold Fusion” field. According to this conjecture, the main part of the energy produced in Low Energy Nuclear Reaction could be the result of a very special kind of chemical reactions (pico-chemical reactions), induced by a considerable increase of gravity at pico-meter distances (pico-gravity). True nuclear signatures (α-particles emission for instance) could also occur according to the pico-gravity conjecture. But they should be many orders of magnitude lower than would be expected from the energy produced (which is observed experimentally). This conjecture will be tested by analysing the products of the reaction of hydrogen isotopes with selected metals.
4-Space Dirac Theory and LENR
Authors: Evans A. B.

A 4-space Dirac theory, which gives the same transition energies as the standard model, predicts specific distributions of virtual electrons and positrons accompanying bound electrons. If potential barriers are viewed stochastically, it seems possible that this has implications for LENR.
Tracks of Ball Lightning in Apparatus?
Authors: Lewis E. H.
Published: December 2024

Researchers of electrical discharge and electrolysis experiments have been finding microscopic markings that are unusual and anomalous. It is possible that these markings are made by microscopic objects that are in the size range of 400–0.1 Åm. These objects may be a type of microscopic ball lightning. They may share the anomalous characteristics of natural ball lightning. They are also finding highly anomalous material activity and emissions. Pictures of the markings and anomalous effects that were taken by six groups of researchers are shown and interpreted in this article.
On the connection between Kα X-rays and energetic alpha particles in Fleischmann–Pons experiments
Authors: Hagelstein Peter L.
Published: December 2024

X-ray emission at Kα energies has been reported in Fleischmann–Pons experiments, and alpha particle emission has been reported in others. It is possible for energetic alpha particles to result in Kα radiation following impact ionization. As a result, one might imagine that Kα radiation is a signature of energetic ions in these experiments. We have calculated yields for Kα X-rays as a function of the energetic alpha particle energy in PdD. As a result of these calculations, we conclude that it is unlikely that these X-rays are a result of energetic alpha particles. We note that energetic alpha particles can produce excitation in lithium at 478 keV, and that the relative line strength of the Pd Kα , the Pt Kα and the Li 478 keV line can be used as a consistency check for energetic alpha particles.
Vilde dyr forbinder os med naturen

Published: December 2024

I de senere år er børns erfaringer med natur blevet knyttet sammen med deres forståelse af bæredygtighed. Ifølge forskningenleder positive naturerfaringer og oplevelsen af at være en del af naturen til at føle omsorg for den. Omsorgen motiverer for at handle bæredygtigt, et forhold, der bliver beskrevet ved begrebet ’naturforbundethed’. Forskningslitteraturen refererer ofte til natur som et grønt (eller blåt) område – dvs. som et sted, der til forskel fra urbane områder har egenskaber, der stimulerer positive naturerfaringer. Sammenhængen mellem oplevelser med vilde dyr i naturen (både hvirvelløse som fx snegle og edderkopper og hvirveldyr som fx pattedyr og padder) og positive naturerfaringer er derfor ikke afdækket. Vi ved endnu ikke, om vilde dyr i deresegenskab af at være væsner med egne mål og erfaringsverdner kan stimulere børns oplevelse af at være en del af naturen og dermed ultimativt bæredygtig adfærd. Dyr er ellers særlig lette at føle sig forbundet med og føle omsorg for, fordi deres adfærd ofte ligner vores egen. Det kan intuitivt bidrage til at pirre interesse og åbne døren for en spirende forståelse. Dette essay tilbyder en begyndende teoretisk ramme for, hvordan børns oplevelser af vilde dyr kan påvirke deres muligheder for at udvikle naturforbundethed. Essayet udfolder, hvordan iagttagelser af vilde dyr og deres målrettethed i deres naturlige miljø potentielt stimulerer både følelser og erkendelser. Vi peger på tre effekter, nemlig 1) stimulering af nysgerrighed gennem dyrs sansning og handlen, 2) indsigt i naturens mangfoldighed gennem dyrs genkendelige og dog anderledes adfærd og 3) oplevelse af afhængighed af den konkrete omverden. Effekterne af oplevelserne sættes ind i diskussionen om børns naturforbundethed. Vi diskuterer også betydningen af den voksnes involvering og understøttelse af stimuleringen af følelser og erkendelser i udviklingen af børns naturforbundethed.

The transmission of 2-keV electrons through a polyethylene terephthalate (PET) nanocapillary with a diameter of 800 nm and a length of 10 μm is studied. The transmitted electrons are detected using microchannel plate (MCP) with a phosphor screen. It is found that the transmission rate for the transmitted electrons with the incident energy can reach up to 10 % for an aligned capillary in the beam direction, but drops to less than 1% when the tilt angle exceeds the geometrical allowable angle. The transmitted electrons with the incident energy do not move with change of tilt angle, so the incident electrons are not guided in the insulating capillary, which is different from the scenario of positive ions. In the final stage of the transmission, the angular distribution of the transmitted electrons within the geometrical allowable angle splits into two peaks along the observation angle perpendicular to the tilt angle. The time evolution of the transmitted full angular distribution shows that when the beam turns on, the transmission profile forms a single peak. As the incident charge and time accumulate, the transmission profile starts to stretch in the plane perpendicular to the tilt angle and gradually splits into two peaks. When the tilt angle of the nanocapillary exceeds the geometrical allowable angle, this splitting tends to disappear. Simulation of the charge deposition in the capillary directly exposed to the beam indicates the formation of positive charge patches, which are not conducive to guidance, as seen in the case of positive ions. According to the simulation results, we can explain our data. Then, the possible reasons for the splitting the transmission angular profiles are discussed.

The p53 transcription factor family consists of the three members p53, p63 and p73. Both p63 and p73 exist in different isoforms that are well characterized. Isoforms have also been identified for p53 and it has been proposed that they are responsible for increased cancer metastasis. In contrast to the p63 and p73 isoforms, which do not contain truncations in folded domains, most of the p53 isoforms contain only parts of either the DNA binding domain or the oligomerization domain. To better understand the effect of p53 isoforms in cancer we provide here a comprehensive biochemical characterization. With the exception of the Δ40p53α isoform none of the other variants can bind to DNA with high affinity and none can upregulate transcription. Probing with antibodies, DARPins and other interaction partners confirmed that isoforms harboring deletions in the DNA binding domain cannot interact specifically with them, but instead are bound to chaperones and other factors known to interact with misfolded proteins. Expression of isoforms with deletions in the DNA binding domain results in upregulation of cellular chaperones. If the expression level surpasses a threshold, the chaperone system can no longer keep these isoforms soluble resulting in aggregation and co-aggregation with other factors.
A neural correlate of individual odor preference in Drosophila

Published: December 2024

Behavior varies even among genetically identical animals raised in the same environment. However, little is known about the circuit or anatomical origins of this individuality. Here, we demonstrate a neural correlate of
Drosophila
odor preference behavior in the olfactory sensory periphery. Namely, idiosyncratic calcium responses in projection neuron (PN) dendrites and densities of the presynaptic protein Bruchpilot in olfactory receptor neuron (ORN) axon terminals correlate with individual preferences in a choice between two aversive odorants. The ORN-PN synapse appears to be a locus of individuality where microscale variation gives rise to idiosyncratic behavior. Simulating microscale stochasticity in ORN-PN synapses of a 3,062 neuron model of the antennal lobe recapitulates patterns of variation in PN calcium responses matching experiments. Conversely, stochasticity in other compartments of this circuit does not recapitulate those patterns. Our results demonstrate how physiological and microscale structural circuit variations can give rise to individual behavior, even when genetics and environment are held constant.
Evaluation of Presumed Drought Impacted Soils through Phospholipid Fatty Acid (PLFA) Biomarkers in the Sahel Region
Authors: Muhammad Bello, Zainab , Muhammad Sanusi, , Aliero Adamu, Aliyu , Dabai Aliyu, Ibrahim , Rabani Adamou,
Published: December 2024

Aims: The aim of this study is to utilize biomarkers to detect drought induced changes in soil microbial communities within presumed drought impacted soils in selected regions of the Sahel.
Study Design: A correlational study design was used to examine the influence of soil pH in relation to other soil properties (e.g., organic carbon, nitrogen and Phosphorus), while PLFA biomarkers were analysed using principal component analysis and descriptive statistics.
Place and Duration of Study: The study, conducted from May to October 2021, focused on the Sahel region of sub-Saharan Africa, specifically within the territorial boundaries of Nigeria and the Niger Republic.
Methodology:  A study using phospholipid fatty acid (PLFA) biomarkers investigated drought-induced changes in soil microbial communities in the Sahel region. Analysis of 90 soil samples revealed significant correlations between PLFA profiles and soil properties.
Results: The study highlights the significance of site-specific soil management techniques, particularly in regions characterized by low nutrient levels and depleted soil organic matter (SOC) and carbon (SOM). In such regions, targeted applications of organic and inorganic amendments can be necessary to improve soil fertility. While sandy soils in G/Doki (87.1%) would benefit from organic additions for better water retention and nutrient-holding capability, Nkonni's high clay concentration could necessitate better drainage management to avoid waterlogging. Certain PLFA indicators are linked to bacteria and fungi, including C18:1cis9 and C18:1ω9. PLFA biomarkers are impacted by drought's alteration of soil microbial populations. To promote soil health and fertility conservation, it is essential to monitor soil microbial dynamics and implement sustainable agricultural methods.
Conclusion: Soil microbial populations are greatly impacted by drought, which alters PLFA indicators. While certain biomarkers, like C18:0 and C18:1, suggest broad microbial activity, others, including C18:1ω9 and C18:1cis9, are linked to fungi. The following markers are linked to Gram-positive bacteria: i15:0, a15:0, i16:0, i17:0, and cy17:0 for Gram-negative bacteria, which are useful tools for evaluating the effects of soil management techniques, environmental stressors, and climatic variability on agricultural soils. These changes demonstrate the potential of PLFA analysis to connect soil microbial dynamics with soil health and fertility. Drought affects soil microbial communities, affecting soil pH. Higher pH increases organic carbon, organic matter, and calcium levels, while nitrogen and phosphorus levels are minimally affected.
Effects of Climate Change and Greenhouse Gas Emission Relevance to Environmental Stress on Horticultural Crops
Authors: Katiyar Hariom , Singh S.P. , Maurya Rohit , Srivastava Ajit Kumar , Verma Rahul Kumar , Yadav Vijay Kumar
Published: December 2024

Global climate change significantly impacts the yield and quality of sustainable horticulture crops. Rising global temperatures have forced the agricultural community to modify planting and harvesting timetables, frequently calling for earlier crop production. Notably, several concerning elements are brought about by climate change, including greenhouse gas emissions (GHGs), higher temperatures, higher concentrations of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4), ozone depletion (O3), and deforestation. All of these factors exacerbate environmental stresses on crops. Climate change is, therefore, likely to have a negative impact on livestock production and crop yields. Thus, the main goal of the review paper is to provide a thorough summary of the various aspects that affect the production of fruits, vegetables, and plantation crops in horticulture, with a focus on greenhouse gas emissions and environmental stressors like high temperatures, droughts, salinity, and CO2 emissions. This assessment will also look at how new greenhouse technologies and horticultural crop varieties can be used to lessen the adverse effects of climate change on crops.

Published: December 2024

Microorganisms can be found everywhere, bacteria and fungi contaminate human body, houses, workplaces, and environment. Fortunately, among many billions of bacteria, only 1500 can be dangerous for health, causing different disease such as pneumonia or skin infection. In the university environment, students have access to service offices regularly for different purposes. Given that the door handles are not routinely disinfected, the opportunity for the transmission of contaminating microorganisms is great. This study was carried out to evaluate the bacteria on door handles in Madonna University, Nigeria. Samples were collected using the swab-rinse method of the American Public Health Association. Each collected specimen was processed to identify the bacteria in the sample. The following processing techniques were employed: Culture, Gram staining and Biochemical test. The result of the study shows student affairs had Echerichia coli as the highest prevailing organism with 100%. Med lab scienece building had Staphylococcus aureus as the highest prevailing organism with a percentage of 50% Klebsiella pneumoniae with 33.3% and Echerichia coli with 16.7%. Meanwhile the blue and white administrative building had Staphylococcus saprophyticus and Klebsiella pneumoniae as the highest prevailing organism, with a percentage of 40% respectively. Science hall had a 100% prevalence of Klebsiella pneumoniae. This study also revealed the various percentage of gram reactions with gram negative having a higher percentage of reactions than gram positive. Since there are various forms of microorganisms found in the various door handles of these offices, it therefore, recommended that a proper sanitization be carried out from time to time, to ensure complete disinfection of these handles in other to limit or reduce the spread of these microorganisms.
Clinical Perspectives of Managing Epilepsy Across Different Patient Populations with a Focus on Brivaracetam: A Cross-sectional Study among Indian Physicians
Authors: S Manjula , M Krishna Kumar
Published: December 2024

Objective: To evaluate clinicians' preferences, prescribing patterns, and clinical experiences with brivaracetam compared to other antiepileptic drugs, particularly levetiracetam, in the management of epilepsy across different patient populations.
Methodology: This cross-sectional study used a 24-item multi-response questionnaire to gather expert opinion across different Indian settings regarding their perspectives on epilepsy and brivaracetam. Data analysis employed descriptive statistics, with results reported as frequencies and percentages.
Results: The survey included 360 participants. Clinicians showed a strong preference for brivaracetam as the first-line antiepileptic drug in patients with newly diagnosed epilepsy, with 72% favoring it for younger patients and 74% for elderly. This preference was particularly notable for managing partial-onset seizures, as cited by 71% of clinicians. Additionally, 65% reported that partial-onset seizures were the primary reason for switching to brivaracetam from other antiepileptics. Behavioral and psychiatric adverse effects were cited by 60% of clinicians as the main reasons for transitioning from levetiracetam to brivaracetam. Moreover, 47% reported that 10-20% of patients experiencing behavioral changes on levetiracetam were switched to brivaracetam, with 49% noting improved efficacy and behavioral outcomes in 20-30% of these cases. The minimal psychiatric and behavioral side effects of brivaracetam were noted as its main advantage by 41% of clinicians in managing partial-onset seizures. Furthermore, 70% of clinicians preferred brivaracetam for treatment-resistant epilepsy, and approximately half of them preferred it for pediatric partial seizures.
Conclusion: This study highlighted brivaracetam as a preferred antiepileptic drug in clinical practice, especially for managing partial-onset seizures. It serves as an effective alternative for patients experiencing adverse effects with levetiracetam.
Yield Gap Assessment in Senegal and Senegal River Valley: Factors Affecting the Yield Gap and Postharvest Activities Impact on its Improvement
Authors: TOP Arame , SALL Mohamed , Ndao El Hadji Omar
Published: December 2024

Senegalese agriculture relies mainly on seasonal production activities marked with low productivity. This contributes to high dependency on imports as far as food self-sufficiency is concerned. This dependency on cereal imports, primarily of rice, wheat and maize has increased gradually due to their low incentive to produce comparison with cash crops (e.g., peanut and cotton), inappropriate policies and failures in improving agricultural productivity. Domestic agricultural production of cereals in Senegal covers approximately 40% of the country’s demand. And it is characterized by a low level of fertilizer application and low accessibility of inputs such as seeds and fertilizer. Reflecting these obstacles, the dependency of rice and maize on imports in Senegal reaches up to 80% and 50%, respectively.
At the country level, the gap between current and potential yield is estimated to be 49.75% and 79.75% for rice and maize production, respectively. But in the Senegal River Valley, these yield gaps are less severe; they are 37.9% and 58.8% respectively. These yield gaps are caused by biophysical, socio-economic and institutional factors. Among them, problems associated with harvest and postharvest hindrances need to be addressed. And, as domestic financial support for loosening up these constraints is not easy because of a lack of financial capacity of government and farmers, one must look for financial support from overseas. Without funding from outside, many governmental agricultural projects targeting to boost up domestic agricultural production are under danger of failure.

The global shift towards Electric Vehicles (EVs) necessitates the development of efficient and sustainable charging infrastructures. This dissertation explores the design and simulation of a small-scale solar-powered charging system for EVs, leveraging the capabilities of MATLAB. The proposed system aims to charge a 12V, 4.5Ah lithium-ion battery using a 20W solar panel, with a Maximum Power Point Tracking (MPPT) charge controller to optimize power extraction under varying irradiance conditions. The system design involves modeling the solar panel's I-V characteristics using the Shockley diode equation, implementing an MPPT controller based on the Perturb & Observe (P&O) algorithm, employing a buck converter for voltage regulation, and utilizing a Battery Management System (BMS) for safe and efficient battery charging. Mathematical models for each component facilitate accurate simulation, and the system is implemented in MATLAB with subsystems for the solar panel, MPPT controller, DC-DC converter, and battery. Simulations conducted under various conditions, including ideal (1000 W/m² irradiance and 25°C temperature) and partially cloudy weather (400 W/m² irradiance), as well as different initial state-of-charge (SOC) levels (20%, 50%, 80%), demonstrate the system's performance in terms of SOC progression, charging current, and power output. Results show that under ideal conditions, the battery reaches 100% SOC in approximately 2.84 hours, whereas under partially cloudy conditions, it only reaches around 70% SOC in 5 hours. These findings highlight the feasibility and efficiency of solar-powered EV charging systems, with the MPPT controller effectively optimizing power output to adapt to varying environmental conditions.

Global researcher and consumer prioritize protecting the atmosphere and biodiversity by promoting eco-friendly products, favoring natural fibers over synthetic materials for their bio-renewable properties and sustainability benefits. The main aim of the review paper was to study the different grasses and their utilization. The author focused on Grass fibres, their sources, properties, and application and their scope for sustainable development ins textile industry. Grasses are somewhat unique in that they frequently succeed in displacing other plants from wide areas of land. Grass fibers are another group of monocotyledonous fibers, where the entire stem together with the leaves are pulped and used in papermaking. Such pulps are composed not only of fibers, but of other cellular elements as well. However, very few individuals recognise the value of grasses. While several plant families provide for human needs, the grass family out performs all others in terms of the quantity and quality of its output. Not much of the work has been done on grass fibres. Hence the need of the hour was felt to explore the potential application of Golden grass (sabai grass fibre), Nettle grass, Vetvier grass, Nappier grass and Gajar grass so as to find sustainable solutions for textile sector.

Single-cell RNA sequencing (scRNA-seq) data allows to create cell type specific transcriptome profiles. Such profiles can be aligned with genome-wide association studies (GWASs) to implicate cell type specificity of the traits. Current methods typically rely only on a small subset of available scRNA-seq datasets, and integrating multiple datasets is hampered by complex batch effects. Here we collated 43 publicly available scRNA-seq datasets. We propose a 3-step workflow with conditional analyses within and between datasets, circumventing batch effects, to uncover associations of traits with cell types. Applying this method to 26 traits, we identify independent associations of multiple cell types. These results lead to starting points for follow-up functional studies aimed at gaining a mechanistic understanding of these traits. The proposed framework as well as the curated scRNA-seq datasets are made available via an online platform, FUMA, to facilitate rapid evaluation of cell type specificity by other researchers.

Materialistic values and green apparel purchase intention among young Vietnamese consumers
Authors: Nguyen Mai Thi Tuyet , Nguyen Linh Hoang , Nguyen Hung Vu

Purpose

Nowadays, the issues related to pro-environmental, sustainable and green consumption behaviors are attracting significant attention from both scholars and practitioners. However, in the context of emerging countries, less research effort has been invested in this topic, especially in investigating young consumer purchase behavior. The purpose of this study is to investigate factors driving young adult Vietnamese consumers’ purchase intention toward green apparel products with emphasis on the role of materialistic values.

Design/methodology/approach

In this research, a conceptual framework is proposed integrating the theory of planned behavior (TPB) model with an important consumer value, materialism. To test the research model and hypotheses, a survey of a sample of 245 young adults (under 25 years old) was conducted in Hanoi, the capital city and one of the two most populous cities in Vietnam. All the scales used in this study were established in the literature, and the scales’ reliability and validity were assessed through Cronbach’s alpha and confirmatory factor analysis. The structural equation modeling (SEM) was used to test the proposed model and hypotheses.

Findings

In this study, six hypotheses were tested and five out of six received support from the data. Specifically, the results of SEM showed that all three antecedents from the TPB model (i.e. attitude, subjective norms and perceived behavioral control) were positive contributors to green apparel purchase intention, of which subjective norms were found to be the most influential predictor of purchase intention. With regard to the roles of the three components of materialism, the findings provided empirical evidence for supporting the positive impact of “success” and the negative impact of “centrality” on the attitude toward green apparel purchase, while “happiness” component was not found to have a significant impact on attitude. In this study, income as a control variable was found to be positively related to purchase intention toward green apparel products.

Originality/value

There is a little research on the relationship between specific values and environment-friendly behaviors, especially in the context of emerging economies such as Vietnam. In addition, it has been suggested that the relationship between materialistic values and green purchase behavior is still unclear. Thus, it is important to have a deeper understanding of the role of materialistic values in green apparel purchase among young adult consumers in the context of Vietnam, an Asian emerging country where only modest research effort has been given to explore this important topic.
