Assessment of Steering Knuckle by DFMAE Method
Steering knuckle is the main part of the steering and suspension system various link of suspension and steering are linked to it and depend on the steering knuckle. Therefore, it requires high precision, quality and durability. The strength component is always in demand for race car application. Earlier if the knuckle fails the design team used to modify the design part by trial and error method. Now we are using DFMAE method followed by experimental analysis. The two step process has been used for the same. First part involves modeling and analysis of steering knuckle by CATIA V5 R21 and ANSYS 16.0. The second step is experimental stress analysis by using strain gauge. Strain gauge is component which senses the stress acting on component and the give the result in form of stress vs time. In automotive suspension, the knuckle is the main part through the suspension wishbone link are connected and the suspension spring are on the wishbone. The hub and braking systems are mounted on the steering knuckle to complete the wheel assembly. The wheel and tyre assembly attach to the hub or spindle of the knuckle where the tire/wheel rotates while being held in a stable plane of motion by the knuckle/suspension assembly. Failure region were identified from the static and dynamic analysis and results compared to experimental analysis by using strain gauge. And this analysis carried out under all operating conditions.

A perspective of the residents on the annoyances and problems of street trees in Visakhapatnam city, Andhra Pradesh, India.
Street trees are an integral component of urban resident’s life. The environmental, economic, and social benefits they provide to residential and commercial areas are crucial for the maintenance of healthy communities. Urban areas cannot function properly without street trees. Despite trees' many benefits, it is important to remember that if they are not properly planned, planted, and maintained, they can become a source of trouble, additional expense, and even danger. Since most of this study is conducted in the Visakhapatnam metropolitan city, it is unclear if these results may be generalized to other city communities or nations. A one-way ANOVA test is performed to see any significant difference in the overall opinion of each annoying factor given by the local neighborhood residents from different study areas in Visakhapatnam city. Generally, people like street trees and their surroundings, and six community respondents rated annoyances as more serious. According to questionnaire surveys, hidden traffic signs and preventing sunlight from entering homes are two of the greatest annoyances of street trees. Before proceeding to the next and final phase of the investigation, they will undoubtedly generate some preliminary ideas for potential responses. All of these must be completed so that suitable street trees can be incorporated into the final design in the future.

Clinical audit on diagnosis and management of hypertension in a primary medical care setting in Sri Lanka
Hypertension has been a leading cause of premature deaths worldwide and it is more prominent in low and middle-income countries and rising. Proper diagnosis and management of hypertension can reduce complications and disability. A new protocol to manage hypertension in primary medical care centers was introduced by American Heart Association to reduce the cost of treatment while managing the patients properly. It was introduced in PMCs of Kalutara district in Sri Lanka with the help of the Resolve to save lives organization. This clinical audit was conducted in 3 PMCs with 163 participants to identify lapses before scaling up the project to more PMCs. It was found that the mean time taken from the first BP measurement to the second measurement in the 140-159/90-99mmHg group (Group A) was 1.07 weeks (SD=2.04 weeks) while the protocol requires measuring the second value between 2 to 4 weeks. Out of basic investigations, FBS and Serum Cholesterol levels were done in 56.4% and 38% of the participants respectively while ECG and UFRs completed in the study were very less. Further, 55.4% (n=87) of the participants aged 80 years or less were managed with 2 drugs according to the protocol while only 20% (n=1) of the patients aged more than 80 years were managed with 1 drug according to the protocol. Only 22 (45.8%) out of 48 participants who required stepping up of drug management was correctly done. Furthermore, the variation between the 3 hospitals in results was, considerable. The requirement of training for healthcare workers in PMCs to standardise the management was emphasized while the resource allocation for laboratory services for investigations was highlighted after the study.

A survey to understand the doctors’ perception of laboratory diagnostics
Clinical laboratories play a crucial role in the healthcare system by assisting doctors in diagnosing and treating patients. In India, there are numerous diagnostic facilities available to doctors and patients, but chain laboratory facilities have demonstrated some advantages over traditional laboratory facilities. To gain insight into the perspective of doctors regarding chain diagnostic facilities, we conducted a survey that focused on Thyrocare Laboratories Ltd, one of the oldest and most established chains in India. A total of 1038 doctors from various specialties and regions were surveyed through both online and offline channels, and the results indicated that almost all doctors (98%) considered laboratory testing to be important for diagnosis. Among these doctors, 83% were aware of Thyrocare Laboratories. Additionally, 9 out of 10 doctors aware of Thyrocare Laboratories stated that they would recommend Thyrocare to patients for pathology evaluations (91%), that the reports from Thyrocare were accurate and reliable (92%), and that their patients had a satisfactory experience with Thyrocare (93%). These survey findings indicate that Thyrocare has a strong market position and is highly regarded for delivering high-quality reliable test results.

Experimental study of the effect of primary nozzle position on the performance of jet ejector
In this work the effect of primary nozzle positions relative to the mixing section in an ejector on the performance of the air ejector are investigated. Air jet ejector and four types of nozzles are designed and constructed. Two nozzles are circular and the other two are squared. Then an apparatus is designed and constructed to achieve the ejector performance (enhancing the entrainment ratio). Due to the rapid decreasing of air flow rate coming from air reservoir of the compressor to the ejector, a data acquisition system is used to record different measurements such as pressure, temperature and velocity at different locations on the test apparatus. The convergent nozzle can be moved to study the effect of nozzle positions on the ejector performance. Tests are carried out at three different positions for each nozzle, the distance between it was equal. At the 1st position, the exit section of the primary nozzle is located just at the inlet plane of the mixing section of the ejector. At the 2nd position, the exit section of the primary nozzle is shifted 8.5 mm before the inlet plane of the mixing section. For the 3rd position, the exit section of the primary nozzle is shifted 17 mm before the inlet plane of the mixing section. From detailed analysis of experimental results, it is found that: The performance of the ejector is affected by the nozzle position, and the optimum position which achieves a maximum entrainment ratio for all nozzles is at position (1), (nearest position to mixing section of the ejector. But the entrainment ratio increases when the nozzle is placed at position (2) in case of the small squared nozzle. Position (3) is the worst position for all nozzle and achieves minimum entrainment ratio. Regardless the position of the primary nozzle, there is a strong relation between the nozzle exit area and the performance of the ejector, i.e. decreasing of primary nozzle exit area increases ejector entrainment ratio.
