Comprehensive Seismic Performance Assessment of Low Rise RC Buildings by Numerical Modelling
In the context of Nepal, Nepal lies in the tectonic plate zone between Indian and Eurasian plates and due to the collision of these plates Himalayan mountain ranges were formed and this result number of earthquakes have occurred in past and in present. The geology is different as there is variation in latitude and longitude, which may result in different ground motion. As there is variation in ground motion there is a variation on earthquake intensity which may change the performance of the low rise buildings. And for the study, 10 different irregular low rise buildings are used. For the proper study linear static analysis is done to check time period of models and check displacement, drift and storey shear on linear static analysis. Later on, the model is checked and analyzed using nonlinear pushover analysis. Model is made nonlinear by making the beam as per existing condition using section designer and hinges were introduced on the beam and column as per FEMA-356 and ATC-40. For the execution of nonlinear analysis both push-in x and push in Y direction load is applied in controlled displacement mode. After execution of nonlinear pushover analysis different colour of hinges were formed and study. And maximum displacement, max storey drift and storey shear were found both in X and Y direction. Peak ground acceleration of Gorkha, EI Centro and Kobe earthquake is used for time history analysis, and different twelve ground motion is used for analysis, and after analysis results, max displacement, base shear, max storey drift was found and the result shown in graphs, which concluded that model having a same irregular plan but with different structure size is more seismically strong, after nonlinear dynamic analysis, model has less value of design value than demand value, so need to rectify and strengthen models.

Formulation, development and sensory acceptability of high calorie snack bars
Background: The demand for consumption of healthy, innovative, processed and convenience foods are increasing rapidly due to increasing in awareness about health and lack of time to cook has led to the development of cereal bars. Study focused on developing high calorie snack bars to be used as a complementary food for malnutrition. Objectives: To develop high calorie millet-based snack bar as a complementary food for malnutrition. Materials and methods: Snack bars were made with millets, nuts and oil seeds, sweeteners and gum. The optimized composite mix formulation was enriched with inulin. The developed bars were evaluated for sensory acceptability using 9-point hedonic scale. Physical characteristics and nutrient content were estimated. Results: The high calorie bar was prepared with locally available ingredients. The sensorial attributes of bars made with jaggery scored higher in comparison with other sweeteners. The developed bars had calorific value of 402-430 kcal/100gm with protein content in the range of 11%, fat 13-14%, fibre 2-3% and carbohydrates 57- 64%. Calcium content ranged from 44.1 -70.9 mg, iron 2-3mg, whereas zinc 50.41mg and magnesium 2.04mg/100g was constant in all samples. Conclusion: Incorporation of millets enhanced the functional and nutrient content of snack bars and could be used as a functional ingredient for better health.

Identification of public realm aspects in connection to the trends of urbanization in Indian cities
If the population keeps growing and lands are desired, there is always a need to explore the numerous directions of how the city immediately emerges. The new trend for future development and urbanization is higher density development. The barrier between advocacy of higher density environment and social sustainability asks for a descriptive and systematic interpretation for inclusive growth. The paper discusses the dynamics of urbanization trends and the immediate attention that has to be considered to ensure quality public life through understanding and finding the aspects of public realm. This work investigates several ways of how the public spaces are manifested and understood. The intent of the paper is to identify the aspects of public realm which could contribute to a resourceful organization of public spaces.

The SIR Model: Spread of Disease (COVID-19) in Ethiopia
The recent emergence of COVID-19 a pandemic is the top of the issues in the Globe. The spread of disease is more and there are several phases of Outbreaks and propagandas to aware their people by the Government and various public interested organizations. Even the daily reports on this Pandemic increased with respect to times or days. In Ethiopia, the Government announced State of Emergency (SOE) to protect the people. After observing these situations, the thrust of analysis of Spread of disease leads this article. Based on the daily reports from the authorized concern bodies that is Ministry of Health (MOH) , Ethiopia providing daily reports and it was recorded by the authors and the data were made. Conclusion: There is no any special significance of spread of diseases (COVID-19) in Ethiopia; it has the same pattern in spread of diseases as like the overall world. By maintain the practice of Hygiene and social distance the spread may reduce in Ethiopia.

Challenges in the development of a new obturation device: A questionnaire survey
Dental anatomy plays a crucial role in human body as it helps in survival. The after treatment protocol in the root canal treatment (RCT) for improper functioning of the anatomy is major challenge for dentists. RCT deals with repairing and saving the tooth that is badly decayed or becomes infected. The RCT, if analyzed mechanically; various factors governs efficacy of the treatment out of which incomplete filling and sealing of 3D root canal space with suitable biomaterial against bacterial growth is major parameter. Today, thanks to modern technologies satisfactory results are obtained, but the cost of treatment is substantially increased which is unaffordable. Thus, a survey was carried by visiting doctors practicing for more than 25 years in conservative dentistry to recent students admitted to dental surgery in various colleges to understand tools/aids used during RCT with hypothesis of developing low cost obturation device for augmenting the dental device feasibility. The success rate of obturation device is high over hand pluggers; but the cost parameter limits the usage of same. The survey also coveys that complete sealing is also not possible with hand pluggers as well as existing available aids, and thus there is a need to develop a low cost obturation device using dual energy (low operating frequency and heat) source for increasing efficacy of treatment. To test feasibility of the collected data, it’s being analyzed through p-test (p>0.05) for selected parameters and correlation was found to be statistically significant.

Black hole attack detection and prevention by Grey Wolf Optimization
In this work, a detailed description of attacks in wireless sensor networks is presented and after this detailed literature review on the related approaches is resented. The review of different approaches and their methodology helps to improve the methodology of the work and helps to enhance the knowledge related to different types of attacks and their solution on WSN. This work presented the work on the optimization of energy and reduction in delay and packet loss during the communication on network. The optimization performed by using the grey wolf optimization algorithm which is a global optimizer that optimizes the results for effective and efficient outcomes. It improves the packet delivery rate, throughput, and reduces energy consumption and delay.
