Adoption of Digital Learning Technology: An Empirical Analysis of the Determinants in Telecom Sector []


Technology has advanced significantly from the analogue period to the digital era. Digital Learning Technology (DLT) is a learning paradigm based on the use of ubiquitous latest technologies, by using smart devices. It can be described as a learning environment that is assisted in daily life by wireless networks, mobile, and embedded computers. It aims to offer content and interaction to students wherever they are, at any time. The learning process has advanced thanks to the technology revolution, which has also fundamentally altered how knowledge is shared and learned. At present, there exist other frameworks too, but they are centered towards different paradigms, and point of view pertaining to DLT with its emphasis on Telecommunication Sector has not been taken into consideration. As, existing frameworks are centered towards different environments hence there exists a need to add dimensions of Empowered Learner, Digital Citizen, Knowledge Curator, Innovative Designer, Computational Thinker and Creator, Communicator & Global Collaborator. These have not been integrated together in existing available research. The study will ascertain level of knowledge of DLT and examine factors which affect the adoption rate, use, and role of DLT in telecoms setups. The results of this research will help create a framework that, if used in any academic or learning setting in a technology-based firm.

Fabrication of Nanostructured Cadmium Selenide Thin Films and Study of its Electrical Properties []


Cadmium selenide (CdSe) thin films having different thicknesses were prepared by thermal vacuum evaporation method onto precleaned amorphous glass substrate. The surface morphological properties of as prepared CdSe films have been characterized by various techniques, such as, X-ray diffraction (XRD), EDAX, field emission scanning electron microscopy (FESEM). XRD studies identify that the as-deposited CdSe films are highly oriented to [100] direction and they belong to nanocrystalline hexagonal phase. The lattice parameters (a = 4.292 and c = 7.012) and crystallite size (D) were calculated and found to be 156 nm. FESEM investigation confirms that films were uniformly deposited over the surface and particles in irregular morphologies in the form of fibrous texture. The electrical properties of the films have been evaluated such as resistivity (5.115 x 10-3 ohm-cm), carrier concentration (4.79 x 1012 /cm3), mobility (2020.2 cm2/Volt-Sec), activation energy (0.295 – 0.305 eV). TEP measurement confirms the deposited films are of P type semiconducting in nature.

Revolutionizing Irrigation in Morocco: A Performance Analysis of Low-Pressure Drip Systems []


In the water-scarce MENA region, with a focal emphasis on Marrakech, Morocco, efficient water, and energy utilization in agriculture is paramount. This research aimed to evaluate and compare the performance of traditional drip emitters, commonly adopted by regional farmers, to that of emerging low-pressure emitters. Over a duration of 365 days, both systems underwent rigorous testing on their irrigation patterns, flow rates, and associated energy consumption. Findings from this study indicated a modest increase of 0.59% in water consumption with the low-pressure emitters. More notably, however, there was a substantial reduction in energy consumption of approximately 63.84%. When assessed on a specific energy basis, low-pressure systems demonstrated a remarkable efficiency, consuming just 6.04 W/m^3 compared to traditional emitters that consumed 17.14 W/m^3. This highlights a potential energy savings of 64.76% with the low-pressure system. Given the region's challenges with water and energy resources, this study provides compelling evidence in favor of adopting low-pressure emitters as a sustainable and efficient alternative in the MENA agricultural landscape.

The study also identifies strategies that organizations have successfully employed to overcome these obstacles, leading to improved security and operational efficiency. The findings highlight ZTA’s ability to reduce security incidents through automation and enhanced monitoring. While there are technical challenges to implementing Zero Trust, the research concludes that the framework is essential for maintaining a strong security posture. Future areas for exploration include the role of technologies like artificial intelligence and machine learning in further improving ZTA.

Optimizing Energy Efficiency through Vertical Greenery Systems []


As modern buildings become more airtight to improve energy efficiency, indoor air quality can decline due to reduced ventilation and increased energy use. Plants offer a viable solution to this problem by enhancing indoor air quality through CO2 reduction, humidity control, and pollutant filtration, while also providing cooling and psychological benefits. The primary mechanisms involved are photosynthesis, which absorbs CO2 and releases oxygen, and transpiration/evapotranspiration, which cools indoor environments and improves air quality. Recent advancements in vertical greenery systems (VGS) have significantly enhanced indoor phytoremediation by optimizing space and plant biomass. VGS can reduce indoor temperatures by up to 6°C, decrease cooling energy consumption by up to 58.9%, and lower CO2 levels by up to 17%, offering considerable environmental and economic benefits. The effectiveness of VGS depends on factors such as plant species, light conditions, and CO2 levels, with optimal lighting and substrate moisture improving CO2 assimilation and cooling effects. However, challenges such as high initial costs, maintenance requirements, and climate-specific performance issues persist. This review examines the mechanisms by which plants regulate temperature, humidity, and CO2 levels, evaluates the effectiveness of VGS, and discusses factors influencing their performance. It also addresses the current limitations of VGS and provides recommendations for future improvements.
