Abstract

The China-Pakistan Economic Corridor (CPEC) is a massive in-progress construction project in Pakistan that connects more than 70 countries via multiple trade channels such as highways, railways, roads, and fiber optics. This project also involves the development of local infrastructure and industrial zones in Pakistan, which demands the discovery of new resources of aggregate to facilitate the construction. Therefore, physical characterization research was carried out on the Kirman hill region (Jurassic limestone), District Kurram, Pakistan, to investigate their suitability for utilization as construction materials using site investigation and laboratory studies. The results outline that all typical engineering parameters are within acceptable limits set by international standards like BS, ASTM, and AASHTO. Bituminous tests revealed that Jurassic limestone is appropriate as an aggregate for asphalt wearing coarse. Likewise, the petrographic study performed shows proper matching with engineering tests. The petrographic analysis of Jurassic limestone showed a minute amount of deleterious content; as a result, it is resistant to Alkali silica reaction (ASR) and Alkali carbonate reaction (ACR) expansions. Based on engineering and petrographic analysis, the Jurassic limestone, Kirman hill region, District Kurram, Pakistan is recommended as a potential aggregate for (i.e., base course, subbase course, cement concrete, and asphalt) and other mega and minor civil construction projects. Doi: 10.28991/CEJ-2022-08-03-02 Full Text: PDF

Abstract

Background: Focus is the main thing for learning, but students still come across distractions in their environment, anxiety, and mental fatigue. Essential oil aromatherapy may improve cognitive functions through neurophysiological mechanisms.Objective: To find out if the combination of ginger and lemon essential oils would help concentration of midwifery students during self-directed learning.Methods: 92 Andalas University midwifery students were randomly assigned to two groups; experimental (aromatherapy, n=46) and control (n=46). The ginger- lemon aromatherapy (40:60 ratio) was given to the experimental group by a ultrasonic diffuser during four weekly 90-minute tutorials. Concentration was determined through a 20-item questionnaire that was validated and which assessed motivation, sustained attention, anxiety regulation, comprehension efficiency, and distraction resistance.Results: Concentration of the experimental group raised significantly from 2.388 to 4.243 (p<0.001, Cohen's d=14.52), whereas the control group did not show any change (p=0.075). The main changes: 37% of the distraction resistance was increased, 23% of the comprehension efficiency was enhanced, and 10% of the anxiety was reduced.Conclusion: Ginger-lemon aromatherapy is an effective way to hype up concentration in learning from different angles by the synergistic anxiolytic and cognitive-stimulating mechanisms, thus giving a simple, cheap educational intervention.
