Psychological contracts are defined as the beliefs individuals hold regarding the terms and conditions of the exchange agreement between themselves and their organizations. The study aims at understanding the depth of Psychological contracts at Western Ahmedabad fast- food joints and its relation with employee’s commitment. It was indeed a challenge to understand Psychological contracts in this particular sector as its growing at a fast pace and evolving a cutthroat competition. Three Psychological Contract Variables- Relational, Balanced and Transactional were employed on 60 crew member from 7 FastFood Joints. A 16 item Psychological Contract inventory to measure employees’ commitment was adopted from PCI of Donald Cable. The study revealed all the three variables in the study, however where commitment was concerned the Dominant one was Transactional commitment. The work concludes with an orientation that, Psychological Contract Variables has lot to do with Lifes’- Orientation of each individual employee.
Dental caries is a major concern effecting most of the individuals today. Statistics show that 69% of adults aged 35 to 44 years have lost permanent tooth due to accident, gum disease failed root canal or tooth decay. Dental plaque is a general term for the diverse microbial community found on tooth surface, embedded in matrix of polymers of bacteria. Nanoparticles considered being of a size not greater than 100 nm have unique properties to combat infection. Nanocomposite is a matrix to which nanoparticles have been added to improve a particular property of the material. The present study deals with the antimicrobial studies of nanocomposite preparations of Titanium dioxide and Zinc oxide. Titanium dioxide and Zinc oxide nanocomposites are found to be effective in inhibiting the growth of bacteria. The present work is to prepare different proportions of nanocomposites of these oxides and find out if the effectivity is more when compared to using the nanoparticle alone. Some nanocomposite materials have been shown to be 1000 times tougher than the bulk component materials. The study carried out shows that the antimicrobial activity of nanocomposites is more effective than the nanoparticle alone providing best alternative to dental implant surgery.
Aim: Dental caries occurs as a result of acid produced by bacteria which destroys the enamel and underlying dentin. A study was carried out to isolate microorganisms that cause dental caries in patients belonging to different age groups and find out the antimicrobial activity of various toothpastes against them.
Study Design: Collection of samples for isolation of caries causing organisms, to identify them using biochemical tests and test the activity of herbal toothpastes against them.
Place and duration of study: Samples were collected from Krish Multispeciality Clinic and Prashanth Dental Clinic, Nagole between June’2016 – December’2017 and worked on, at Microbiology Department, St. Francis College for women, Hyderabad.
Methodology: Ten samples of each age group from 10-20 yrs., 20-40 yrs. and 40-60 yrs. were isolated. The organisms were identified by carrying out various biochemical tests according to Bergey’s Manual of Systematic Bacteriology and molecular characterization based on 16s rRNA typing. Identified organisms were used to test the antimicrobial activity of herbal toothpastes by employing agar well diffusion method. ANOVA is used for statistical analysis.
Results and Conclusion: Patanjali herbal products like Dantkanti are gaining lot of importance and have become a part of life of common man because of their effectivity. Our studies revealed that out of the various toothpastes tested, Patanjali toothpaste had good antimicrobial activity against all the isolates. On comparative analysis of f-ratio and P significant value (< .05.) of all pairs, it is observed that Patanjali has good antimicrobial activity against all isolates tested. The efficacy of Meswak is almost similar to that of Patanjali.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
