Introduction: Rubella is a mild exanthematous illness caused by Rubella virus which belongs to the family Togaviridae. Rubella is considered of public health importance for the teratogenic potential of the virus, this lead to disastrous consequences in pregnant women if contracted during first trimester. An effective and safe vaccine against rubella is available, yet according to estimation, over 100,000 infants are born with Congenital Rubella Syndrome (CRS) annually worldwide. Rubella is endemic in India and CRS contributes in morbidity and mortality among the live birth. As rubella vaccine has been incorporated in their immunisation schedule, the incidence of rubella has been reduced drastically. But still seronegative population has been noted in various studies in India. Aim: To evaluate the immune status (Rubella specific IgG antibody) of Rubella among Health Care Workers (HCW) of our hospital. Materials and Methods: A prospective, cross-sectional study was conducted among female health care students and workers (n=145) in a tertiary care teaching hospital in South Chennai from January to February 2017. Blood samples were collected after getting informed consent and serum was separated. A rubella specific IgG antibody was detected by ELISA using the commercially available kit as per the manufacturer's instruction. Samples showing IgG antibody titre >10 IU/mL were taken as positive and =10 IU/mL as negative. The results were analysed statistically using Epi Info version 7.2. Results: A total n=145 samples were analysed and among which 124 (85.5%) workers had adequate titre and 21 (14.48%) were negative for rubella IgG antibody. The mean age of the participants was 19.65. The participants were MBBS students (n=75), BDS students (n=48), Laboratory technicians (n=12), Staff nurses (n=9) and Doctor (n=1). None of them was remembering their vaccination status. Conclusion: The study concludes that immunisation of HCWs against rubella is an important target regardless of their vaccination status. There is a more chance of exposure to infection and also in transmission of infection in the hospital environment. Hence, maintenance of immunity is an essential part of prevention and infection control scheme. [ABSTRACT FROM AUTHOR]

This study focuses on the synthesis and characterization of hybrid zinc oxide/silver ion (ZnO/Ag+) nanocomposites tailored for PV cell applications. The nanocomposites are synthesized through a cost-effective method, leveraging the unique properties of both ZnO and Ag. Characterization techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM) are employed to analyze the structural, morphological and optical properties of the nanocomposites. Moreover, the electrical properties and photoelectric performance of the PV solar cells are evaluated and compared with conventional PV devices. The results demonstrate the potential of ZnO/Ag+ nanocomposites in enhancing the overall performance of PV solar cells. [ABSTRACT FROM AUTHOR]

Let R be a commutative ring with identity, Z(R) its set of all zero-divisors, and H a nonempty proper multiplicative prime subset of R: The generalized total graph GTH(R) of R is the simple undirected graph with vertex set R and two distinct vertices x and y are adjacent if and only if x + y ∊ H. If we take R as the field F and H = {0}, we designate the graph as the generalized total graph of the field F and denote the same as GT(F). In this paper, we investigate several graph theoretical properties of the generalized total graph GT(F) and its complement GT(F). In particular, we discuss about properties like Eulerian and Hamiltonian for GT(F). [ABSTRACT FROM AUTHOR]

Indian Writing English is matured from a sapling to deep rooted tree where it shelters over millions of people by exploring the writers in various branches. Among explored writers, Amit Chaudhuri is a writer in versatile. He is a poet, novelist, critic, essayist, singer and also a good musician. Amit Chaudhuri belongs to Calcutta, his works excessively explicit the impact of a particular perspective of own domain, Calcutta. Chaudhuri's first novel A Strange and Sublime Address explores the domestic values of middle class family in the city of Calcutta where the family gives more importance to traditional and cultural values of ancestral home. Chaudhuri has described the city of Calcutta in parallel fashions as City of Joy and City of Chaos. The protagonist of the novel is twelve years old boy, Sandeep and Chaudhuri has portrayed the distinct instances of domestic obsession of the characters can be observed in the novel. Hence, the present paper focuses on domestic perception of Calcutta city conceited by Amit Chaudhuri in his AStrange and Sublime Address. [ABSTRACT FROM AUTHOR]

Transparent brittle ceramics such as soda-lime glass pose unique challenges for performing full-field optical measurement of deformations and stresses to characterize fracture and failure behaviors. Low fracture toughness coupled with high stiffness and elastic wave speeds are among the factors responsible for some of these challenges as deformations tend to be small and confined to an extremely small region near the stress concentrators. Need for strong birefringence, elaborate optics, or lack of sufficient measurement sensitivity are some of the factors against legacy techniques such as photoelasticity, optical interferometry, and speckle methods, respectively, to study soda-lime glass. Motivated by these factors, the feasibility of Digital Gradient Sensing ( DGS) method to measure crack-tip and contact-induced deformations in soda-lime glass under quasi-static loading is demonstrated. This first of a two parts paper demonstrates the applicability of DGS for the problem under quasi-static loading condition. The optical measurements are used to evaluate the relevant parameters and compare with the analytical solutions. The second part of this study is focused on measuring contact-point and crack-tip deformations during impact-induced stress wave loading. [ABSTRACT FROM AUTHOR]
