Recommendations to Solve the Problem of a Lack of Computer Skills Among CLB 4 and 5 Learners at the LINC Center

The purpose of this study was to provide recommendations to solve the problem of a lack of computer skills among Canadian Language Benchmark (CLB) 4 and 5 learners at the Language Instruction for Newcomers to Canada (LINC) Center. The problem was that CLB 4 and 5 learners do not have basic computer skills. When the school switched to online mode during the pandemic, most teachers were not sure how to teach and assess learners using technology. Around 75% of learners asked the coordinator to withdraw from the program as they felt they did not get the same teaching quality as the traditional method. The rationale for this study was that learning with technology may enhance the learners’ academic achievements and equip them with all the necessary skills needed in the workplace so the community would have well-trained immigrants who attract more businesses, and employers would consider the graduates of this school for employment. Consequently, the provincial government would notice a decrease in social assistance applications, and schools would get more funds. The school may also earn higher online rankings and reviews. For this reason, the central research question was, “How can the problem of a lack of computer skills among CLB 4 and 5 learners be solved at the LINC Center?” Three forms of data were collected. The first data collection method was interviews with teachers and administrators at LINC in Mississauga, Ontario. The second form of data collection was a focus group with teachers, and the third was a survey administered to all instructors. Recommendations to solve the problem included creating professional learning communities (PLCs) and providing blended professional development to teachers

Harnessing the future: a comprehensive overview of renewable energy solutions

LAUREA MAGISTRALEI settori in crescita dei veicoli elettrici (EV), dell'energia solare e dell'energia eolica sono oggetto di studio in questa ricerca. Viene evidenziato il loro ruolo nell'evoluzione dei sistemi energetici sostenibili. L'introduzione sottolinea la necessità di una transizione verso le fonti di energia rinnovabile come soluzione alle crescenti esigenze energetiche globali e alle sfide climatiche. Fornisce inoltre i quadri di riferimento per comprendere l'interazione di queste tecnologie nel più ampio contesto della sostenibilità, dell'efficienza energetica e delle strategie di riduzione delle emissioni. Questa ricerca esplora i principali benefici ambientali legati all'adozione dei veicoli elettrici, come la riduzione delle emissioni di gas serra e il miglioramento della qualità dell'aria. Vengono analizzati i progressi nella tecnologia delle batterie e nelle infrastrutture di ricarica, poiché rivestono un ruolo fondamentale nell'aumento della fiducia dei consumatori verso l'adozione degli EV. Per quanto riguarda l'energia solare, la ricerca valuta i miglioramenti nelle tecnologie fotovoltaiche e nei sistemi di accumulo energetico, che ne aumentano l'efficienza e ne riducono i costi, favorendone quindi una maggiore diffusione. Inoltre, il lavoro analizza la crescita dell'energia eolica come attore chiave nel settore delle rinnovabili, evidenziando il ruolo dello sviluppo di turbine più grandi ed efficienti e dell'integrazione con le tecnologie delle reti intelligenti. Integrando le tendenze attuali, le innovazioni tecnologiche e i quadri normativi, questa ricerca fornisce una panoramica completa sul futuro delle energie rinnovabili e sul loro potenziale nel rispondere in modo efficace alle esigenze energetiche globali e alle sfide climatiche.The growing fields of Electric Vehicles (EVs), solar energy, and wind energy are investigated in this research. Their roles in the evolution of sustainable energy systems are highlighted. The introduction highlights the necessity for changing to renewable energy sources as a solution towards global energy demands and climate challenges. it provides the frameworks for understanding the interaction of these technologies within the broader context of sustainability, energy efficiency, and strategies for emission reduction. This research explores the major environmental benefits related to the adoption of EVs, such as a reduction in greenhouse gas emissions and improvements in air quality. The improvements in battery technology and charging infrastructure are investigated because of their importance in increasing consumer confidence in adopting EVs. Regarding solar energy, the research evaluates the improvements in photovoltaic technologies and energy storage systems that boost efficiency and reduce costs. Therefore, the scope of their implementation will be promoted. Moreover, the paper analyzes the growth of wind energy as a major player in the renewable sector. It is dependent upon the development of larger, more efficient turbines and the integration of smart grid technologies. By integrating current trends, technological innovations, and policy frameworks, this research provides a comprehensive overview of the future landscape of renewable energy and its potential to address global energy demands and climate challenges effectively

Hydrogen aircraft concepts and ground support

As worldwide petroleum supplies diminish and prices escalate, the aviation industry will be forced to consider relying on energy resources other than kerosene for its aviation fuel needs. Additionally, there is growing environmental concern regarding greenhouse emissions particularly as aircraft cause pollution in sensitive layers of the atmosphere. These are serious implications necessitating prudence in seeking alternative fuels sooner rather than later. Liquid Hydrogen (LH2) combustion produces zero CO2 emissions, very little NOx, and water providing a solution to sustain air traffic growth whilst preventing further atmospheric pollution. Hydrogen itself is abundant and can be produced from renewable sources meaning worldwide availability and sustainability permitting sustainable growth of aviation at high rates (typically 4-5% per year). Despite these major advantages, there are compromises to be made. The low density fuel means ingenuity must be exercised to design an aircraft configuration which will accommodate a fuel volume more than four times that which would normally be required. Practical unconventional aircraft conceptual designs providing solutions to this problem are presented including estimates of performance, mass, and relative cost- and energy-effectiveness. To provide a means to produce, store and transport the fuel safely and efficiently, ground support operations have been systematically checked and the required airport infrastructure defined. Technical issues such as safety, airworthiness certification, environmental issues and system synergies are also discussed, and an outline plan is presented providing the R&D necessary to introduce LH2-fuelled civil aircraft into service. This Thesis proves that LH2 has sufficient long term promise to justify more substantial R&D offering possible improvement in performance and engine reliability. The overall cost for a LH2 aircraft are within reasonable values, and the requirement for new equipment to maintain and support LH2-fuelled aircraft is not extensive. Importantly LH2 is at least as safe
