The Paradigm Shift in School Education in Sindh: From Traditional Learning to Smart Learning
No full textModern education needs smart learning systems because traditional methods prevail in the Sindh region and other areas. This research adopts a qualitative approach to explore three essential elements: the present learning environment, the necessity of transitioning to smart learning, and barriers to its implementation. Data were collected through semi-structured interviews with educators and administrators, alongside classroom observations. Thematic analysis revealed that traditional teacher-focused methods remain dominant over digital learning approaches in the study area. Participants highlighted that smart learning can enhance student engagement, creativity, and academic outcomes. However, various challenges hinder implementation, including inadequate infrastructure, lack of trained personnel, insufficient policy support, and limited funding. Classroom observations confirmed that schools face dual issues—scarcity of digital resources and teacher resistance to technological change. The study underscores the urgent need for strategic policy reforms, targeted professional development, and dedicated financial investment in digital infrastructure to support the successful adoption of smart learning environments. The findings provide actionable recommendations for educational leaders seeking sustainable digital transformation across both public and private institutions in Sindh
Dolomite quarry waste as sand replacement in sand brick
No full textLink to publisher's homepage at http://www.scientific.netDolomite is a sedimentary rock resulting from the deposition of river or sea takes millions of years. The quarry waste from dolomite production had been used to replace sand in order to study the performance of modified brick sand. The objectives of this research are to determine the density, water absorption rate, and compressive strength of the new dolomite brick (d-brick) and to find out the optimum percentage of sand replacement with the dolomite waste. The bricks sample are then be tested using physical and mechanical approach. The percent of sand replacement is 25%, 50%, 75%, and 100% by weight.The optimum percentage mix of the modified sand brick using dolomite is D50 based on the density, water absorption, and compressive strength test of the sand brick. The result of the density of the D50 sand brick using dolomite is 1701 kg/m3, the water absorption of the sand brick 12%, and 14% at 7 days, and 28 days respectively. Meanwhile, the compressive strength of the D50 sand brick is 7.99 MPa, and 12.28 MPa at 7 days, and 28 days
Underbalanced Nitrified Foam Drilling Enabled Extensive Reservoir Characterization and Production from a Highly Depleted Formation in Dhodak Field in Pakistan: A Case History
No full textAbstract
The Dhodak field is located in the eastern Sulaiman Range in Pakistan. The first well drilled there in 1975 produced gas and condensate from the Pab sandstone intervals created in the Cretaceous Age. Drilling any well in the field results in severe circulation losses because of the younger carbonate horizons of the Eocene Age, which includes the Habib Rahi and Rubbly Limestone. Operators cure these losses by spotting lost-circulation material (LCM) pills and deploying numerous cement plugs. In one particular well in the Dhodak field, an operator encountered an unexpected well-control scenario when drilling through the Rubbly Limestone, which further confirmed the potential for hydrocarbons in the horizon.
To explore the potential of the Rubbly Limestone, the operator drilled a dedicated well named Rubbly-1 using a conventional mud system and, as expected, encountered total loss of circulation. Drilling continued to the target depth, with heavy LCM pills and four cement plugs to cure losses. A prospective production interval was identified, and subsequent drill stem testing (DST) was performed. The well did not flow in the DST even after numerous attempts to kick it off. An evaluation determined that bridging materials had extensively invaded the formation when attempting to cure losses. The invading materials had clogged the pores of the reservoir formation, which resulted in no production and subsequent abandonment of the well.
Underbalanced drilling provided a feasible solution that allowed the well to flow while drilling and eliminated overbalanced pressures and invasion damage. The reservoir pressure measured just 5 lb/gal (599 kg/m3) in equivalent mud weight. The low pressure of the formation meant it could only be drilled with a foam system.
A suitable foam system provided a low equivalent circulating density that enabled drilling the Rubbly Limestone formation. By applying an underbalanced nitrified foam system, the operator drilled the horizontal to the target depth (TD) without any issues. The well started flowing while drilling, and the operator evaluated the reservoir potential by performing surface testing and openhole wireline logging, which resulted in logs with excellent resolution. This paper details the design criteria, equipment selection, and wellsite execution program used for drilling and evaluating the Rubbly Limestone formation.</jats:p

No full textAn Adaptive Game-Based Learning Strategy for Children Road Safety Education and Practice in Virtual Space
No full textVirtual reality (VR) has been widely used as a tool to assist people by letting them learn and simulate situations that are too dangerous and risky to practice in real life, and one of these is road safety training for children. Traditional video- and presentation-based road safety training has average output results as it lacks physical practice and the involvement of children during training, without any practical testing examination to check the learned abilities of a child before their exposure to real-world environments. Therefore, in this paper, we propose a 3D realistic open-ended VR and Kinect sensor-based training setup using the Unity game engine, wherein children are educated and involved in road safety exercises. The proposed system applies the concepts of VR in a game-like setting to let the children learn about traffic rules and practice them in their homes without any risk of being exposed to the outside environment. Thus, with our interactive and immersive training environment, we aim to minimize road accidents involving children and contribute to the generic domain of healthcare. Furthermore, the proposed framework evaluates the overall performance of the students in a virtual environment (VE) to develop their road-awareness skills. To ensure safety, the proposed system has an extra examination layer for children’s abilities evaluation, whereby a child is considered fit for real-world practice in cases where they fulfil certain criteria by achieving set scores. To show the robustness and stability of the proposed system, we conduct four types of subjective activities by involving a group of ten students with average grades in their classes. The experimental results show the positive effect of the proposed system in improving the road crossing behavior of the children
Toward a Green Transition: Unravelling the Impact of Innovation, Urban Dynamics, and Economic Expansion on CO? Emissions in BRICS
No full textEnvironmental degradation from growing carbon dioxide (CO?) emissions now stands as a significant worldwide issue that impacts regions undergoing quick economic expansion. The BRICS nations, which include Brazil as well as Russia, India, China and South Africa, create 45% of global CO? emissions while generating 18% of world GDP, positioning them as key participants in climate discussions at the international level. A statistical analysis evaluates the permanent and temporary relationships between technological innovation and urbanization and economic growth on CO? emission levels among BRICS nations using World Development Indicators (WDI) annual data from 1990 to 2023. Results from PMG-ARDL modelling demonstrate that both technological innovation and consumption of renewable sources actively diminish CO? emission patterns during extended periods, although economic growth helps reduce emissions when certain limitations arise. The relationship between urbanization and the environment becomes difficult to predict since it worsens emissions and demonstrates the intricate relationship between progress and sustainability. According to these results, future sustainability demands immediate implementation of advanced sustainable technologies and proper urban expansion management strategies
