This study was designed to prepare vaccines. Cancer vaccines promote the destruction of cancer cells,and the cancer cells contain special antigens on their surface when the vaccine is given, it acts as an antigen to activate the immune system. The IL-2 stimulates the response to a type of cells called T-cell, and outer membrane vesicle (OMV) targeting cancer cells by stimulating the immunity to respond with it two types including innate andadaptive immunity, that lead to stimulating the immune system to reduce mammary adenocarcinoma induction in lab mice using T4-1 cell line breast cancer by taking blood and serum to evaluate the immune system efficacy. The tumor induction success by monitoring mice body weight loss showed the lost weight began in the third week after tumor induction, so 23.2 g at first and second week to 14.35 g at the end of the fourth week, whereas the control animals were weighed 32.37 g. The immunity system efficacy results appear a difference in blood and serum parameters after cancer induction. The result shows an increase in total WBC and monocytes (5900, 0.2 cells/mm respectively) but non significantly decreased in neutrophils and lymphocytes count (2.6, 5.9 cells/mm, respectively). Therefore, the first and second doses of vaccines increased the antibody and complement of the immune system compared with control. While Eliaza data for cytokines profile referred to elevated IL2 (26.5 pg/ml)in the serum of vaccination mice but only significantly decreased in IL6 and IL-22 amount (20.4 and 19.6 pg/ml respectively) comparing with control.

Background: A new management model for construction and demolition waste (CDW) was proposed for the city of Rio de Janeiro, hence waste the city planning area estimated generation; the results were compared with the data published by COMLURB and SNIS through the statistics tests was proved that CDW had been dispersed, which support the hypothesis that the current model cause dispersion of the rubble. Aim: This study proposes a new management model for CDW to the city, according to regions where occur the higher production of rubble. Methods: The estimation of rubble was obtained through the issued licenses from 2006 to 2020 published by SMPU. The quantification of rubble in the city was carried out by adopting the generation indicator from licensed construction activities. The amount of CDW published by COMLURB and SNIS was compared through statistics tests ANOVA and T-Test, the second period from 2006 to 2020 and 2011 to 2020. To measure the area to implant a CDW recycling plant, criteria from production capacity were used. Results: ANOVA test to data from 2006 to 2020 and 2011 to 2020, according to a confidence interval of 95%, found the P value 0.589 and 0.022, respectively, it was verified that the significant difference is between data from COMLURB and Estimated. The T-test was applied from the same period in data from SNIS and estimated the P values 0.399 and 0.014. Discussion: The data from Estimating between 2006 and 2020 showed the best representation. The Área de Planejamento – AP (Planning Area) 4 was where 50.70% of the total rubble, after the AP 3 with 17.66%, the AP 5 was estimated at 16.59%, last of all, AP 2 and AP 1 were calculated the generation of 8.28% and 6.77%, respectively. Therefore, sizing the CDW recycling producing 361,99.00 tons per year demands an area of 32,397.50 m². Conclusions: It was concluded that the receipt of CDW in transfer stations managed by COMLURB is not allowed; therefore, the need to create a construction waste recycling plant was presented, to this end, it is necessary to have an available area of approximately 32,397.50 m².

Background: Dr. Bhavna, an experienced leader in education and innovation, has held various leadership positions, including head of department, dean of alumni relations, and president of the institutions innovation council. She has been instrumental in initiating the alumni cell at her previous organization and establishing world-class state-of-the-art laboratories in collaboration with the automotive sector. Aims: Dr. Bhavna's efforts aim to create an ecosystem for innovation and entrepreneurship within the institute and beyond, encouraging learners to consider entrepreneurship as a career option and fostering innovation in the electronics manufacturing domain. Methods: Dr. Bhavna's approach involves raising awareness about innovation and entrepreneurship among learners, fostering collaborations between academia and industry, and establishing world-class state-of-the-art laboratories to bridge the gap between academia and industry. Results: Dr. Bhavna's efforts have resulted in a strong alumni network, with graduates across the globe contributing to various domains and positions. She has also established world-class laboratories in collaboration with the automotive sector, fostering innovation and startups in the electronics manufacturing domain. Discussions: The Ministry of Electronics and Information Technology plays a significant role in initiating innovations and startups in the electronics manufacturing domain. They have generated a separate vertical for startups, which poses challenges to innovators. If a solution is validated, the ministry handholds the innovators, incubates their ideas, funds them, and helps them reach the market at the national and international levels. Conclusions: Dr. Bhavna's vision and efforts toward fostering an ecosystem for innovation and entrepreneurship within the institute and beyond are commendable. Her experience and achievements in various leadership roles, including as the head of the department and president of the institutions innovation council, have added significant value to her professional and personal life.
