Abstract

Rathore has proposed a systematic method of obtaining a chain/necklace when the sum of two consecutive numbers is a perfect square or cube. This method is extended to a wide range of algebraic operations on the two consecutive numbers;but resticted to a set of numbers
Keywords:Chain, Necklace, Magic circle, Rathore Method, Perfect square.

Abstract

Objective: This study aimed to examine the nutritional habits, the food consumption and emotional eating of high school students studying in two different branches of a private school in Istanbul in the Covid-19 pandemic period. Materials and Methods: The research was carried out between January and July 2022 with students at the ages of 14-19 studying on two separate campuses of a private high school in Istanbul. 105 adolescents (59 female and 46 male) were recruited.A sociodemo graphic form and the Emotional Eating Scale were applied. The Food Consumption Frequency and the 24-hour Food Consumption were recorded. Results and Conclusion:39% of 105 participants had been infected with Covid-19. While 67.1% of adolescents engaged in physical activity before the pandemic, the rate of those who engaged in physical activity decreased to 46.7% during the pandemic.45.7% gained

Abstract

humans approach animal approaches, technological advances are becoming increasingly prevalent and accessible in this environment. With a focus on pets, a factor is much desired, but without a major technological advance, the biomechanics of veterinary orthopedics. Currently what have been attending to paraplegic/quadriplegic animals are wheelchairs and trawl bags, however, their uses are still very limited. This is because dogs with low mobility should take turns between the drag bag for everyday life and the wheelchair for physical exercises, and exercises are extremely important to avoid muscle atrophy, overweight, depression, and dependence on the tutor. However, this relay is not practical and this ends up stimulating abandonment or rejection of the animal within.....

Abstract

The level of validation of the operation of parts subjected to sudden shocks in a mechanical system characterizes the quality and resistance of the materials used as well as their limits, which are mainly determined by defects in shape and caused by various factors intervening in the process of manufacturing, geometry, type of constraints and transformation required. Based on the finite element tool, this article aims to study by numerical simulation the two types of steels (35CrMo4, C40) in industrial and agricultural activities most commonly used and consumed in manufacturing and to study their reaction. to sudden mechanical stresses through numerical models of the CHARPY test known from KCU and KCV in order to avoid sudden damage and to open the possibility of improvement by heat or other treatment if necessary, it is therefore necessary to determine the effect of these forces applied in order to choose the most suitable one which avoids cracking under the effect of contacts. The JONSON CKOOK model can guide us to the desired results and answer the questions posed.
