The transition temperature TC and the specific heat jump δC/TC in La2-xBaxCuO4, Bi 2Can-1SrnCunO2n+4 and Tl2Can-1Ba2CunO 2n+3(2n+4) are calculated using exotic pairing model. These values are calculated at both buckling mode and breathing mode. The values calculated are compared with known experimental values. If δ is the gap in the allowed energy states, then the jump in the specific heat is C S-Cn. These results show that the calculated values of the ratios and TC compare well with experimental values.

Background: Globally, the majority of people with HIV/AIDS live in sub-Saharan Africa. While the increasing availability of antiretroviral therapy is improving the outlook for many, its effects are yet to reach all of those in need and patients still present with advanced disease. This paper reports findings from qualitative interviews with patients living with AIDS and their caregivers who were receiving palliative care from Hospice Africa Uganda (HAU). We aimed to understand what motivated patients and their families to seek formal healthcare, whether there were any barriers to help- seeking and how the help and support provided to them by HAU was perceived. Methods: We invited patients with AIDS and their relatives who were newly referred to HAU to participate in qualitative interviews. Patients and carers were interviewed in their homes approximately four weeks after the patient's enrolment at HAU. Interviews were translated, transcribed and analysed using narrative and thematic approaches. Results: Interviews were completed with 22 patients (10 women and 12 men) and 20 family caregivers, nominated by patients. Interviews revealed the extent of suffering patients endured and the strain that family caregivers experienced before help was sought or accessed. Patients reported a wide range of severe physical symptoms. Patients and their relatives reported worries about the disclosure of the AIDS diagnosis and fear of stigma. Profound poverty framed all accounts. Poverty and stigma were, depending on the patient and family situation, both motivators and barriers to help seeking behaviour. Hospice services were perceived to provide essential relief of pain and symptoms, as well as providing rehabilitative support and a sense of caring. The hospice was perceived relieve utter destitution, although it was unable to meet all the expectations that patients had. Conclusion: Hospice care was highly valued and perceived to effectively manage problems such as pain and other symptoms and to provide rehabilitation. Participants noted a strong sense of being "cared for". However, poverty and a sense of stigma were widespread. Further research is needed to understand how poverty and stigma can be effectively managed in hospice care for patients for advanced AIDS and their families. © 2015 Too et al. Source

Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well-defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area. © 2015 American Academy of Forensic Sciences.

The energy conversion efficiency of a conventional pn junction solar cell decreases as the temperature increases, and this may eventually lead to failures in the photovoltaic system, especially if it uses concentrated solar radiation. In this work, we show that spectrally selective reflector (SSR) surfaces can be important for reducing the heat buildup on passively cooled solar cells. We outline a computational scheme for optimizing DC magnetron-sputtered TiO 2:Nb-based SSRs tailored for silicon solar cells and find good agreement of the reflectance with an experimental realization of the optimal SSR. A figure of merit for SSRs has also been derived and applied to the experimental data. © 2011 Optical Society of America. Source

A Plasmodium falciparum in vitro drug sensitive study was conducted in order to evaluate artemisinin in combination with potential anti-malarial drug from the stem bark of Erythrina abyssinica. Abyssinone-v was isolated and thus identified as a potential partner for a fixed combination therapy. Bioassay guided chromatographic separation of Ethyl acetate extract of Erythrina abyssinica led to the isolation of Abyssinone-v with IC 50 value of 3.19 μg/ml against chloroquine-sensitive (D6) P. falciparum parasites. The structure of abyssinone-v was determined using nuclear magnetic resonance (NMR) and mass spectroscopic technique. The interaction of artemisinin and abyssinone-v was analyzed using combination ratios of 10:90 to 90:10 respectively against P. falciparum parasites. This led to the identification of anti-malarial combination therapy of artemisinin and abyssinone-v with sum of fraction inhibiting concentration (FIC) of 0.79 at a ratio of 2:3, respectively. ©2011 Academic Journals.
