On the Diffraction Model Approach to Cluster Stripping Nuclear Reactions

Abstract. In this study, the diffraction model is employed to study the clus-ter stripping nuclear reaction on the basis of the Regge-pole method. A for-mula for the angular distribution is derived. The angular distribution spectra for the cluster stripping nuclear reactions 40Ca(3He,p)42Sc, 40Ca(t, p)42Ca and 54Fe(t, p)56Fe at various energies have been well reproduced with projectile energies varying between 10 MeV and 15 MeV. The predicted theoretical re-sults for the cluster stripping reactions 40Ca(3He,p)42Sc with 10 MeV, 12 MeV and 15 MeV incident 3He; 40Ca(t, p)42Ca with 10.1 MeV incident triton; and 54Fe(t, p)56Fe with 12 MeV incident triton were compared with the experimen-tal data and good agreement was observed. Also a comparison between the diffraction model prediction of the angular distribution values for the cluster stripping reaction 40Ca(3He,p)42Sc at energy 12 MeV of 3He and that of the distorted-wave Born approximation (DWBA) is implemented and a satisfactory agreement between the two methods has been attained.

Prospects for the Development of Investment Activities of Insurance Organizations

The relevance of the research topic lies in the need to improve the efficiency of the investment activities of national insurance organizations, since, taking into account world experience, investment activities should provide the main income of insurance companies, which will allow, in a significant way, to regularly increase equity capital and improve financial condition, and in general, provide the possibility of developing the national insurance market and having a positive impact on the development of the national economy

PREVALENCE OF COMPLICATIONS AFTER ODONTOPLASTY

Background:Cosmetic dentistry, also known as enameloplasty, is what odontoplasty refers to. This cosmetic dentistry treatment that strives to enhance the function of human teeth also includes contouring and reshaping of the teeth. Enhancing the look of a persons teeth by modifying their size, length, or even shape is a popular cosmetic procedure nowadays. This research aimed to assess and understand the issues and complications that are reported to have been faced by many people who have gone through the procedure of odontoplasty. Methods:A cross-sectional study was used to understand the prevalence of complications after odontoplasty. The philosophy of positivism is appropriate for this research as it helped in the descriptive assessment of the quantitative data gathered. An inductive research approach would be implemented because this approach relies on building up new theories and developing perceptions from existing theories. This is the need of this research work, and therefore an approach of inductive nature would be the best fit.The sampling method that was implemented is stratified random sampling, which would help consider those individuals in the UK going through the odontoplasty procedure. The sample age group is within the range of 25-40 years. Results:Study included 562 participants in which all of them responded to study survey questions. The most frequent complication was weak tooth (n= 268, 47.7%). More than third of study participants didnt support the changing of natural appearance of the tooth (n= 216, 38.4%). However, 63% would like to further changing the existing shape and size of their teeth (n= 354). On the other hand, 241 participants believed that odontoplasty is a necessity (42.9%). The same percentage almost recommended others to undergo odontoplasty (n= 239, 42.5%). 312 participants felt moderate pain (55.5%) is more than half of study participants. The most frequent reason why participants underwent odontolplasty was bad shape of teeth (n= 259, 46.1%). Conclusion:The most prevalent consequence was weak teeth. More over a third of survey participants opposed altering the tooths natural look, according to the study findings. However, more than half of individuals would desire to modify their present tooth form and size. Some participants, however, thought that odontoplasty is necessary. Over fifty percent of subjects reported moderate discomfort. About half of them claimed that it would endure for extended period of tim
