Project management study on metro tunneling project- A case study on BKC metro project
The primary aim of the study was to identify the risks involved in the “Line-III” of the metro project in Mumbai. A comprehensive evaluation was done based on a literature review of similar projects, government reports and finally site visit including a comprehensive interview of several teams. Some of the biggest risks include land acquisition, seasonal problems (monsoon), the safety of nearby buildings, manpower allocation. Thorough analysis and interview helped in identifying sixteen risks in total and then they were subjected to Risk Break Down structure where each of the risks was categorized and its impact and likelihood were determined. Then all of the identified risks were subjected to Impact- Likelihood matrix and risk register were developed. Primarily four risks i.e Clearance from nearby buildings (PAP), Geological Changes in specific radius of the project, Drainage/ Waterlogging, Fire hazard were lying in the red zone of the matrix which suggests that these were the risk that needs proper mitigating strategies first followed by other risks. Diamond analysis of the project based on interviews showed in terms of “novelty” the project could be termed “platform” as new technology like NATBM (New Australian Tunnel Boring Machine) was used but no radical technology was used in the project, in terms of “technology” it was “high-tech”, in terms of “complexity” it could be termed as “systems” as the project involved unique challenges which were resolved by some adaptive approaches, for “pace” the project was “time-critical” as any delay in the overall completion of the project would have resulted in overall increase in cost. Interviews were taken first to identify the risks associated with the project and then to find out the quantitative nature of each question. Thematic analysis of the interview was done and eight prominent themes were identified and then they were subjected to analysis. Scale wise analysis of the questions was done to quantify the qualitative approach of interviews. Overall the project was an innovative one where several risks were involved and there were properly mitigated/ transferred. New technology was used to overcome the unique risks associated with the underground tunneling process. Safety was given top priority in the site as well as the execution approaches used in the project.

Fabrication and experimental setup of manually operated sprayer trolley
The population of India is increasing rapidly in order to fulfill their diet & needs, the production of foods must be increased. But this must come at affordable to everyone. In India farming is done by traditional ways beside that there has been larger development of industry and service sector as compared to that of agriculture sector. To mechanization of agriculture in India some equipment has been developed. The pesticide sprayer is one among them and it is done by traditional farm workers by carrying backpack type sprayer, which requires human effort or by using electric pump. To improve the agriculture system and to reduce the human effort and problems associated with the backpack sprayer new equipment is fabricated which will be beneficial to farmers. Mechanical operated sprayer trolley simply uses kinematic link to convert the kinetic energy to oscillating energy for reciprocating motion of pump. In this system no use of any external energy such as electrical, engine, any renewal energy etc. Also minimize the wastage pesticide and time.

Tracing the original source of FMCG-SCM using Blockchain
Fast Moving Consumer Goods come a long way from the production of their raw materials to finally being bought by the end user, i.e. the customer. Their Supply Chain Management is a tedious task and doesn’t really provide you with an auditable trail. The source and thus the quality of the product raises few questions. The paperwork involved in this leads to days of auditing for even a small discrepancy arising in the whole SCM. One of the obvious solutions to this is the digitalization of the whole process. But that still doesn’t stop it from getting tampered. The truth still poses a question with the quality of the product being consumed by the end user. Adding another level of surety is only possible by ensuring that the data is not tampered with during the whole supply chain of the product. This is only possible by having a blockchain to moderate the whole process. This will not only make sure that the data regarding the product is true to its point but also make the auditing easy and fast in case of any discrepancy. Few western countries have already implemented blockchain for the products which require high quality throughout the supply chain. Since the type of supply chains vary and data privacy is required in some stages between different parties, private blockchains are preferred in such scenarios to create that balance between truth auditability and data privacy.

Evaluation of three commercially available toothpaste/creams for resolution of white spot lesions – An in vitro study
White spot lesions are often seen on the teeth after orthodontic treatment, resulting in unpleasant esthetics. Despite many attempts at prevention of white spot lesions, its prevalence remains very high on debonding. The aim of the study was to evaluate the efficiency of 3 commercially available toothpaste/creams in the remineralization of white spot lesions. Materials and Methods: Hundred extracted premolars were selected as sample teeth. They were mounted into an acrylic resin block and randomly divided into four groups, consisting of 25 teeth each. Premolar brackets were bonded to facial surfaces. The specimens were color-coded with Yellow (Group-1), Red (Group-2), Green (Group-3) and Blue (Group-4). Sample teeth were exposed to demineralization solution for 14 days to produce white spot lesion. Visual verification of white spot lesions was done after 14 days on all sample teeth and brackets were debonded. The comparison between 4 groups: Artificial saliva (Group 1), Colgate PreviDent 5000 toothpaste (Group 2), GC Tooth mousse tooth crème (Group 3), Clinpro tooth crème (Group 4), were done at pre-treatment, 14-days after demineralization, 7-days after treatment, 14-days after treatment, 21-days after treatment and 28-days after treatment using Gloss meter and Surface Profilometer instrument. Results: The mean 28 days after treatment Gloss meter values for Group 1 (Artificial saliva) were 20.69±2.41 GU, for Group 2 (PreviDent 5000 toothpaste) were 21.70±2.06 GU, for Group 3 (Tooth mousse tooth crème) were 23.59±2.40 GU and for Group 4 (Clinpro tooth crème) were 22.56±2.98 GU respectively. And mean 28 days after treatment Profilometer values for Group 1 (Artificial saliva) were 1.84 ± 0.50µm, for Group 2 (PreviDent 5000 toothpaste) were 1.542 ± 0.33µm, for Group 3 (Tooth mousse tooth crème) were 1.254 ± 0.08µm and for Group 4 (Clinpro tooth crème) were 1.475 ± 0.20µm respectively. Conclusion: The result of the study indicated that Gc Tooth mousse tooth crème, PreviDent 5000 toothpaste, and Clinpro tooth crème have higher remineralization potential compared to Artificial saliva. Gc tooth mouse crème had the highest remineralization potential followed by Clinpro tooth crème and PreviDent 5000 in both Gloss meter test and Profilometer test. The increased efficiency of Tooth Mousse in remineralizing white spot lesion might be because of the combined effect of CPP –APP and fluoride which was not there in all other groups.

Noxious effect of preservatives
Food is an important source of energy like carbohydrates, proteins which are required for the survival and to perform cellular activities by an organism. Due to the urban lifestyle, the demand for processed food has rapidly increased. Since food can’t be stored for a longer period of time, natural or synthetic class of food additives called preservatives are added intentionally in limited quantities to increase the shelf life of food by preventing the growth of micro- organism. Since all organisms are structurally and functionally inter connected these food preservatives have an harmful effect on human after prolonged exposure.
