Giant dipole resonance with exact treatment of thermal fluctuations

The shape fluctuations due to thermal effects in the giant dipole resonance (GDR) observables are calculated using the exact free energies evaluated at fixed spin and temperature. The results obtained are compared with Landau theory calculations done by parameterizing the free energy. The Landau theory is found to be insufficient when the shell effects are dominating.Comment: 5 pages, 2 figure

Synthesis of metakaolin alkali based geopolymer for Hydrogen adsorption study

Hydrogen is not only an energy carrier but it’s also one of the substituting source that can be replace fossil fuels. Therefore possible adsorbent extensively being tested for better hydrogen adsorption. Recently, there are researches on hydrogen storage by using developed materials such as complex hydride, carbon nanotubes, zeolites and alloy metal. Geopolymer is proposed as a potential adsorbent due to economically and environmental friendly properties and lower cost compared to other developed materials and also derived from industrial waste. Thus, the scope of the hydrogen storage is wide, the author has narrowed down his study on hydrogen adsorption by using synthesized metakaolin alkali based geopolymer. Different molarity of alkali activator of sodium hydroxide (NaOH) of 8M, 10M and 12M were used to synthesis raw material of metakaolin in order to find which one is the best parameter for hydrogen adsorption uptake. Result shown that hydrogen adsorption on least molarity of alkali activator (8M), it adsorbs about 1.34 weight percentage though slightly lower than alkali activator of 12M which has about 1.49 weight percent. In nutshell, as molarity of the alkali activator (NaOH) increases, the hydrogen adsorption (wt%) also increases

Applicability of shape parameterizations for giant dipole resonance in warm and rapidly rotating nuclei

We investigate how well the shape parameterizations are applicable for studying the giant dipole resonance (GDR) in nuclei, in the low temperature and/or high spin regime. The shape fluctuations due to thermal effects in the GDR observables are calculated using the actual free energies evaluated at fixed spin and temperature. The results obtained are compared with Landau theory calculations done by parameterizing the free energy. We exemplify that the Landau theory could be inadequate where shell effects are dominating. This discrepancy at low temperatures and high spins are well reflected in GDR observables and hence insists on exact calculations in such cases.Comment: 10 pages, 2 figure

Modification of Asphalt Binder by Incorporating Coconut Shell Powder

This research objective is to determine the performance of coconut shell powder with bitumen comparing with base bitumen of grade 60/70 pen and grade 80/100 pen in terms of strength and stability. Coconut shell is chosen because it is a natural waste product which can be recycled and cheaper in cost. Besides, this is also way to reduce the waste product of coconut and to reduce pollution by using natural product. The coconut shell are crushed into powder of ASTM no.100 or 150 micron. Then, the coconut shell powder were added to modify the bitumen of grade 60/70 pen and grade 80/100 pen. The base bitumen and modified bitumen were tested with different test such as Penetration Test, Softening Point Test and Ductility Test. This test were carried out for the virgin bitumen and aged bitumen which were aged using Rolling Thin Film Oven Test (RTFOT) which simulate short term aging process and Pressure Aging Vessel (PAV) Test which simulate long term aging process. The results achieved for base bitumen and modified bitumen are analyzed and compared to determine the rheological properties and physical properties of modified bitumen of grade 60/70 pen and modified bitumen of grade 80/100 pen

Construction industry and women: a review of the barriers

The UK construction industry has a particularly low participation rate for women. Currently there are over 11 million women employed in the UK, accounting for almost 50% of the work force. However, despite increases in the number of women employed in the construction over the past decade, they still constitute only 9% of the work force. This means that the construction industry will continue to be male dominated. It is found that women are confronted by a significant number of barriers, beginning with difficulties in joining the field of construction through to capturing the most senior position in the organisation’s hierarchy. In this context, this paper presents a review of the literature on the current status of women in the construction; in particular, it discusses the barriers which prevent women’s entry and retention in the construction industry

Toronto extremity salvage score-patient reported outcome measures in upper extremity bone tumors treated with limb salvage surgery

Bone and soft tissue tumors of upper extremity are relatively uncommon than those of lower limb. Treating these patients while retaining a functional limb is quite a challenge. Along with musculoskeletal tumor society score, Toronto extremity salvage score (TESS) is most widely used patient-reported outcome measure for sarcomas of upper extremity. Retrospective analysis of patients with upper extremity bone tumors (24) treated with limb salvage surgery (20) from 2014 to 2022 was undertaken.  Mean follow-up period was 26 months and mean age was 30.2 years. Out of 20, 11 humerus cases were of tumors arising from humerus, 5 in radius and 3 in ulna. 9 patients were treated with custom mega prosthesis reconstruction, 6 with fibular free flap, 6 radius underwent simple resection and 1 curettage. Majority of the cases were giant cell tumors (8) followed by osteosarcoma (3), fibromatosis (3), aneurysmal bone cyst (2), simple bone cyst (2), 1 Ewing sarcoma and 1 metastatic bone disease. The mean TESS score of the sample population was 69.7 Most of the patients (11) rated their disability to be of moderate degree and considered themselves to be moderately disabled. The mean TESS score for CMP group was 71.1, while that of autograft reconstruction was 68.3. Despite only half the population having received CMP as a reconstructive option, nearly 40% patients with disease of forearm where the results are not so great, our study population reported a reasonably good patient reported outcome score. A dedicated physiotherapy team with tailor made exercise protocol for each patient depending on their needs can help in improving the quality of life
