Local total anti-magic chromatic number of graphs.

Let G=(V,E) be a graph without isolated vertices and let |V(G)|=n and |E(G)|=m. A bijection π:V(G)∪E(G)→{1,2,....,n+m} is said to be local total anti-magic labeling of a graph G if it satisfies the conditions: (i.) for any edge uv, ω(u)≠ω(v), where u and v in V(G) (ii.) for any two adjacent edges e and e', ω(e)≠ω(e') (iii.) for any edge uv∈E(G) is incident to the vertex v, ω(v)≠ω(uv), where weight of vertex u is, ω(u)=∑e∈S(u)π(e), S(u) is the set of edges with every edge of S(u) one end vertex is u and an edge weight is ω(e=uv)=π(u)+π(v). In this paper, we have introduced a local total anti-magic labeling (LTAL) and the local total anti-magic chromatic number (LTACN). Also, we obtain the LTACN for the graphs Pn, K1,n, Fn and Sn,n.

Prospect and retrospect of 3D bio-printing.

3D bioprinting has become a popular medical technique in recent years. The most compelling rationale for the development of 3D bioprinting is the paucity of biological structures required for the rehabilitation of missing organs and tissues. They're useful in a multitude of domains, including disease modelling, regenerative medicine, tissue engineering, drug discovery with testing, personalised medicine, organ development, toxicity studies, and implants. Bioprinting requires a range of bioprinting technologies and bioinks to finish their procedure, that Inkjet-based bioprinting, extrusion-based bioprinting, laser-assisted bioprinting, stereolithography-based bioprinting, and in situ bioprinting are some of the technologies listed here. Bioink is a 3D printing material that is used to construct engineered artificial living tissue. It can be constructed solely for cells, but it usually includes a carrier substance that envelops the cells, then there's Agarose-based bioinks, alginate-based bioinks, collagen-based bioinks, and hyaluronic acid-based bioinks, to name a few. Here we presented about the different bioprinting methods with the use of bioinks in it and then Prospected over various applications in different fields.

Socio-Demographic and Clinical Correlates of Exclusive Breastfeeding practices up to Six Months of Age.

BACKGROUND: According to the recommendations from The World Health Organization, exclusive breast feeding (EBF) should be given to infants for the first six months for healthy growth and development. However, developing countries have a wide range of variation in the practice of EBF. From this study, we aim to estimate the duration of EBF and find the impact of socio-demographic characteristics on EBF. MATERIALS AND METHODS: This study was conducted at PSG Institute of Medical Sciences and Research, Coimbatore in the month of July 2018. Mothers with children aged below 4 years attending the paediatric outpatient department were included in the study. Kaplan-Meier curve analysis and logistic regression analysis were employed. RESULTS: Our analysis indicates that the prevalence of EBF was 58.4% among infants up to 6 months of age with mean duration of EBF 4.52 months. It was observed that mothers of a younger age (15-24 years) and with lower socio-economic status were negatively associated with the practice of providing EBF to infants up to six months of age. CONCLUSION: The findings clearly indicate that the interventions related to EBF up to six months of age should be targeted at women in the lower socio-economic status and at younger ages.
