Design, analysis and manufacturing of flexible and functional stirrup and steel profile bundle-tie manufacturing machine
Manufacturing process costs can be reduced by providing the mechanization of labor-intensive works such as construction and logistic operations in profile rolling. Although there are certain manual and semi-automatic machines available for the production of stirrups on constructions, using of physical strengths can not be eliminated, and these machines can not be used effectively for the production of steel profile bundle tie. In this study, it is aimed to design, analyze and manufacture of a functional machine based on hydraulic and automation system which has the flexibility to perform not only the production of bundle tie used in the transporting processes of the hot rolled steel profiles but also the stirrups used in construction sectors. The required process times for material feeding - straightening, bending, cutting and twisting operations were calculated. In line with the calculations, drive and transport mechanisms were designed and the motor-reducer pair was selected and the hydraulic cylinders and hydraulic power unit were dimensioned by using numerical engineering calculations. In order to validate the torque requirements of the motor-reducer groups which are calculated by using numerical engineering calculation methods, finite element method supported bending analyzes are performed and torque-time curves were obtained and the drive systems of the designed mechanisms are verified. Stress-time diagrams of Grade-75 rods, which are the raw material of bundle-tie production, are also obtained during the validation of the drive systems by finite element method supported analyzes. The bending regions of the bars were examined on the basis of the stress-strain diagram and the plastic forming capabilities of the process are evaluated. By this means, applying of excessive plastic deformation of the workpiece is prevented and optimizing of the final product's mechanical behavior is provided. By using the data obtained within the scope of the study, a flexible and functional structured machine was designed and manufactured which can perform many kinds of plastic deformation processes successfully.

Prediction of Indoor PM2.5 concentrations using Support Vector Regression
Studies have found that exposure to elevated levels of PM2.5 concentrations, both in the long term and short term, has adverse health effects. The risk of exposure in the indoor microenvironment is higher compared to that of outdoor because people spend a significant amount of their time indoors. Therefore to mitigate the health risks, it becomes essential to maintain indoor PM2.5 levels. To do so, keeping an eye on the future expected concentrations is equally important as monitoring the current PM2.5 levels. This paper talks about the development of one such model that enables us to predict the indoor PM2.5 concentrations using Support Vector Regression. Upon development the model showed a very high value of R-square (0.98) and while testing it yielded a very low error (3.78%).

A study on China-U.S. trade war
This paper provides a comprehensive analysis of the on-going China-US trade war, similar to the Thucydides Trap in terms of competing for global economic dominance. It analyzes what the US attempts to achieve through the trade war and why China has been refusing the reciprocal trade relations urged by President Trump. It also identifies social and economic changes in American society, which motivate President Trump to impose punitive tariffs on Chinese goods. It emphasizes that the trade war is asymmetric and China will definitely suffer more losses than the US if the trade war escalates further. At the end of the paper, it suggests that to avoid the devastating result of the Thucydides Trap, China should further open its domestic market to American companies and actively pursue negotiations with the US for resolving the dispute. If trade tensions between the United States and certain trading partners escalate into a full-blown trade war, what should developing countries do? Using a global, general equilibrium model, this paper first simulates the effects of an increase in U.S. tariffs on imports from all regions to about 30 percent (the average non-Most Favored Nation tariff currently applied to imports and retaliation in kind by major trading partners- the European Union, China, Mexico, Canada, and Japan. The paper then considers four possible responses by developing countries to this trade war: (i) join the trade war; (ii) do nothing; (iii) pursue regional trade agreements with all regions outside the United States; and (iv) option (iii) and unilaterally liberalize tariffs on imports from the United States. The results show that joining the trade war is the worst option for developing countries (twice as bad as doing nothing) while forming RTAs with non-U.S. regions and liberalizing tariffs on U.S. imports (“turning the other cheek”) is the best. The reason is that a trade war between the United States and its major trading partners creates opportunities for developing countries to increase their exports to these markets. Liberalizing tariffs increases developing countries’ competitiveness, enabling them to capitalize on these opportunities.

Resisting SBZ attack patterns by a reliable trust model in Vehicular Ad Hoc Network (VANET)
Vehicular ad hoc networks (VANETs) have the probable to convert the way people travel through the formation of a safe interoperable wireless communications network that contains buses, cars, traffic signals, cell phones, and other devices. However, VANETs are susceptible to security threats due to growing reliance on computing, communication, and control technologies. The sole security and privacy challenges modeled by VANETs include integrity, no repudiation, confidentiality, real-time operational constraints/demands, access control, privacy protection, and availability. In this paper, we recommend that the new trust management scheme mainly focuses on the Traffic Estimation and Prediction System which generally provides the predictive information needed for proactive traffic control and traveler information. In VANETs singular vehicles can help each other's find assets and build up dependability under profoundly powerful conditions; without any unified trust expert to determine the precision and unwavering quality of data aggregated in a distributed manner we present a new trust management system for such networks. The trustworthiness of VANETs could be upgraded by addressing holistically both node trust, which is defined as how trustworthy the nodes in VANETs are and data trust, which is defined as the assessment of whether or not and to what extent the reported traffic data are trustworthy. To make this trust-based system robust we include a way of dealing with false ratings. More specifically a reliable trust model is proposed which can resist the SBZ attack patterns by using the cloud watch mechanism which can exclude potential lies. The effectiveness and efficiency of the proposed scheme are validated through extensive experiments. The proposed trust management theme is applicable to a wide range of VANET applications to improve traffic safety, mobility, and environmental protection with enhanced trustworthiness.

Emotional intelligence among adolescent boys
Adolescents go through emotional ups and downs all the time due to change of hormones and for them life without much experience might seem overwhelming and at this juncture, a young adult can feel misguided. Emotional intelligence refers to the capacity of recognizing our own feelings and those of others, for motivating ourselves, and for managing emotions well in us and in our relationships Emotional Intelligence is highly important in a teen’s development. There is considerable evidence pointing to its positive role in helping students deal with stress, develop relationships, and handle the transitions facing them. Present study aims to findout the emotional intelligence among adolescent boys, using random sampling technique 120 (60 urban and 60 rural) adolescent boys were taken. An exploratory design was used for the study. Emotional intelligence test developed by Dr.Ekta Sharma(2011)is used to measure emotional intelligence of students. The obtained result of the study revealed there is no significant difference among adolescent boys on emotional intelligence

A review on detoxification methodologies in Siddha – A traditional Indian system of medicine
Siddha System is one of the oldest system practiced in South India especially in Tamil Nadu. Now a days Traditional system are highly encouraged by the public for treating diseases. But the major claim against the system is toxic nature of minerals and metals are used by the traditional medicines. Siddhar’s who are the inventors of Siddha medicines not only provide the medicinal preparation for treating diseases. They also mentioned the detoxification methodologies for purifying the ingredients of the medicinal preparations not only the metals and minerals even plants they mention it. Purification and Preparation procedure will done as per the literature evidence is the only opportunity to break the claim that higher order medicines are toxic nature. And acceptance of Siddha system of medicine around the world is possible. This article is a finger print review study for availability of many purification methodogies in Siddha system of medicine.
