Agriculture Monitoring System Using IoT: A Review Paper

In recent years evolution of Internet of Things has brought revolution in many different sectors.  The agriculture sector has become efficient and cost effective due to role of IoT. Monitoring systems has become the crucial part of agriculture. In past few years lot of work is been done and many systems has been purposed in this regard. In this paper we are going to make comparison between 4 different agriculture monitoring systems. We are also going to discuss what type of hardware including different sensors are used in those systems. We are also going to discuss software and platform on which those applications run. We will also discuss processing mechanism and what kind of algorithms are used in these systems and in the last we are going to make a comparative table based on these parameters

Hip reconstruction osteotomy by Ilizarov method as a salvage option for abnormal hip joints

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, proximal migration of the femur, lower-extremity length discrepancy, abnormal gait, and pain. In this case series of 37 patients coming to our institution between May 2005 and December 2011, we report our results in treatment of unstable hip joint by hip reconstruction osteotomy using the Ilizarov method and apparatus. This includes an acute valgus and extension osteotomy of the proximal femur combined with gradual varus and distraction (if required) for realignment and lengthening at a second, more distal, femoral osteotomy. 18 males and 19 females participated in the study. There were 17 patients with DDH, 12 with sequelae of septic arthritis, 2 with tuberculous arthritis, 4 with posttraumatic arthritis, and 2 with focal proximal femoral deficiency. Outcomes were evaluated by using Harris Hip Scoring system. At the mean follow-up of 37 months, Harris Hip Score had significantly improved in all patients. To conclude, illizarov hip reconstruction can successfully improve Trendelenburg’s gait. It supports the pelvis and simultaneously restores knee alignment and corrects lower-extremity length discrepancy (LLD)

THE PERCEPTION AND EXPERIENCE OF NURSING STUDENTS REGARDING THE USE OF ACTIVE LEARNING STRATEGIES

Abstract Active learning is a way of teaching rather than a particular, specialized technique. It necessitates active student participation in carefully planned teacher-structured classroom activities. Objective: This study aims to explore nursing students' perceptions and experiences regarding using active learning strategies. Methodology: This cross-sectional study was conducted at the private nursing institute in Karachi, Pakistan, from May to August 2023. Moreover, this study used a convenient sampling technique. The eighty-seven student participants are included in this study. Results: The survey results reveal that a substantial proportion of nursing students strongly agree with the effectiveness and benefits of active learning strategies. Specifically, 40.2% strongly agree that active learning enhances their understanding of complex nursing concepts, while 47.1% and 43.7% strongly agree that active learning activities are more engaging than traditional lectures. Furthermore, 55.2% strongly agree that active learning helps them retain and apply knowledge effectively, and 51.7% strongly agree that it encourages teamwork and collaboration among nursing students. Notably, 83.9% of students prefer active learning over traditional lecture-based teaching. Additionally, 35.6% strongly believe that nursing education can enhance the implementation of active learning strategies through learning objectives. Conclusion: The survey overwhelmingly supports active learning strategies among nursing students. Most strongly agree that active learning enhances understanding, engagement, and knowledge retention, favoring it over traditional lectures, mainly through case studies. Many also believe that integrating clear learning objectives can enhance its effectiveness. These findings underscore the widespread acknowledgment of active learning's positive impact on nursing education, emphasizing its role in improving comprehension and student engagement

The cross-sectional study of anxiety levels and ratio of severity of thirteen symptoms of anxiety among medical students

Background: Anxiety is defined as physical, behavioral, social and psychological response to treat self-concept characterized by subjective, consciously perceived feelings of tension. Nowadays anxiety is most commonly found among medical students. This study was conducted to find out the anxiety levels and ratio of severity of thirteen symptoms of anxiety.Methods: A questionnaire based study was conducted among 178 medical students which tests the level of anxiety and severity of symptoms of anxiety. The questionnaire used was hamilton anxiety rating scale (HAM-A).Results: Out of 178 students, 80 (44.94%) students scored mild anxiety levels, 63 (35.39%) students scored moderate anxiety levels and 35 (19.66%) students scored severe anxiety levels.Conclusions: Mild form of anxiety is much more common among medical students and majority of these medical students are females. Moreover, the symptoms of anxiety including tension, anxious mood, depressed mood, insomnia, fear and CVS symptoms appear with moderate severity in majority of medical students while on the other hand some symptoms including general somatic muscular and sensory symptoms, difficulties in concentration and memory, genitor-urinary symptoms, respiratory symptoms, GIT symptoms and other autonomic symptoms appear with least severity among majority of medical students

Development of An Indigenous Microwave Absorber

This paper describes the design and method in developing a low cost, reliable and good performance microwave absorber for the application in anechoic chamber room measurement. Theoretically, the absorber is designed and to be functioning at a frequency range from 1.5GHz to 15GHz (in pyramidalshaped). However, due to the equipment limitation for measurement, the absorber is only tested for 2GHz and 10GHz frequency. The pyramidal-shaped is chosen since its performance has been proven to work at microwave frequency. A survey on materials that can be used to coat the absorber has been carried out and a variety of the materials are tested. The absorbers are made from polystyrene, which are cut into pyramidal shape and then coated with carbon. The measurement of the pyramidal absorber is carried out in order to determine its performance. Lastly, the results are compared to the commercialized absorber in terms of the absorption performance and found to be less about 22.8% and 10.9% at 2GHz and 10GHz respectivel
