Transformer Parameters Monitoring System using MATLAB Simulink

Transformer is an important component of an electrical distribution system. Hence it is important to monitor transformers for problems before faults occur. This system is about design and implementation of embedded system to monitor and record key parameters of a distribution transformer like load currents,voltage and temperature. It is installed at the distribution transformer site and the above parameters are recorded using the analog to digital converter (ADC) of the embedded system. The obtained parameters are processed and recorded in the system memory. If any abnormality or an emergency situation occurs the system takes immediate action to avoid it. This system will help the transformers to operate smoothly and identify problems before any failure. proposed system is low cost, easy to use capable of monitoring and displaying data using matlab[1,6]

Barriers-enablers-ownership approach: A mixed methods analysis of a social intervention to improve surgical antibiotic prescribing in hospitals

Objectives To assess an intervention for surgical antibiotic prophylaxis (SAP) improvement within surgical teams focused on addressing barriers and fostering enablers and ownership of guideline compliance. Design The Queensland Surgical Antibiotic Prophylaxis (QSAP) study was a multicentre, mixed methods study designed to address barriers and enablers to SAP compliance and facilitate engagement in self-directed audit/feedback and assess the efficacy of the intervention in improving compliance with SAP guidelines. The implementation was assessed using a 24-month interrupted time series design coupled with a qualitative evaluation. Setting The study was undertaken at three hospitals (one regional, two metropolitan) in Australia. Participants SAP-prescribing decisions for 1757 patients undergoing general surgical procedures from three health services were included. Six bimonthly time points, pre-implementation and post implementation of the intervention, were measured. Qualitative interviews were performed with 29 clinical team members. SAP improvements varied across site and time periods. Intervention QSAP embedded ownership of quality improvement in SAP within surgical teams and used known social influences to address barriers to and enablers of optimal SAP prescribing. Results The site that reported senior surgeon engagement showed steady and consistent improvement in prescribing over 24 months (prestudy and poststudy). Multiple factors, including resource issues, influenced engagement and sites/time points where these were present had no improvement in guideline compliance. Conclusions The barriers-enablers-ownership model shows promise in its ability to facilitate prescribing improvements and could be expanded into other areas of antimicrobial stewardship. Senior ownership was a predictor of success (or failure) of the intervention across sites and time periods. The key role of senior leaders in change leadership indicates the critical need to engage other specialties in the stewardship agenda. The influence of contextual factors in limiting engagement clearly identifies issues of resource distributions/inequalities within health systems as limiting antimicrobial optimisation potential

Early infant HIV-1 diagnosis programs in resource-limited settings: opportunities for improved outcomes and more cost-effective interventions

Early infant diagnosis (EID) of HIV-1 infection confers substantial benefits to HIV-infected and HIV-uninfected infants, to their families, and to programs providing prevention of mother-to-child transmission (PMTCT) services, but has been challenging to implement in resource-limited settings. In order to correctly inform parents/caregivers of infant infection status and link HIV-infected infants to care and treatment, a 'cascade' of events must successfully occur. A frequently cited barrier to expansion of EID programs is the cost of the required laboratory assays. However, substantial implementation barriers, as well as personnel and infrastructure requirements, exist at each step in the cascade. In this update, we review challenges to uptake at each step in the EID cascade, highlighting that even with the highest reported levels of uptake, nearly half of HIV-infected infants may not complete the cascade successfully. We next synthesize the available literature about the costs and cost effectiveness of EID programs; identify areas for future research; and place these findings within the context of the benefits and challenges to EID implementation in resource-limited settings

Desecrating the sacred taste: The making of Gurram Jashua-the father of dalit literature in Telugu

The experience of discrimination based on caste, especially the stigma of untouchability, never formed a part of the socio-cultural and intellectual history of modern India. This article focuses on the life of Gurram Jashua (1895-1971) and re-reads the poignant and lived experience of untouchability on the basis of his seminal autobiography and other literary texts written in Telugu. This article argues that in ideas against caste prejudices, it is the themes of self-suffering and lived experience that provide a crucial impetus to the germination of protest. Through an analysis of Jashua's writings, especially Gabbilam, often called the Dalit Bible, this article attempts to capture and record the psychosomatic agony of living under the gaze of caste. With an untouchable whose rebellious spirit questioned the legitimacy of Hindu Brahmanical ideology cast as its hero, Gabbilam's revolutionary intervention subverted the content and form of the classical Telugu literary sphere. It was a socially and politically relevant text because in it, Jashua also engaged with anti-colonial nationalism and other issues of his time. Jashua remains peerless in his ability to express the dark realities of caste harnessed into a literary rhythm, as he continues to be read and admired even by non-Dalits

Politics of identity and the project of writing history in postcolonial India a dalit critique

The central orientation of this article is organised around Dalit identity politics and their implications on the project of writing history in postcolonial India. It critically engages with the Subaltern Studies project as a school of postcolonial historiography that claims to represent the voice of the marginalised and yet stops short of acknowledging caste and caste-based oppression as worthy of historical analysis. In particular, it engages with Dipesh Chakrabarty's reflections on Dalit identity politics in postcolonial India and argues that Dalits, while demanding sociopolitical equality and a dignified identity, also challenge the epistemologies of the nation and demand its historical narratives to be egalitarian and inclusive

Caste from Below: Memory and Subversion of Caste in Chindu Yakshaganam

Based on the life of the noted Chindu Yakshagana performer, Yellamma, this article presents the lived experience of caste through the lens of India’s Dalits, as narrated by the Chindus, a dependent caste of Madigas of Telangana. This provides a glimpse into the inner world of caste-based relationships through analysis of a satellite caste system that remains inaccessible to the dominant Hindu Brahmanical world and most scholarship on caste. Satellite castes function as preservers of social memory and act as cultural archives, enacting caste histories and origin myths, while critiquing and inverting dominant perceptions and weaving positive stories. The article argues that there may well be much more to this performative protest than merely social subversion
