 Abstract

This work describes the preparation of conducting polymer composites and their use as corrosion protection coatings for aluminum and mild steel. Two doped forms of Polyaniline (PANI) (PANI- Dodecylbenzenesulfonic acid-DBSA and PANI-Graphite) were prepared. A new procedure for synthesis of Polyaniline has been developed by inverse emulsion process in order to make it readily soluble in Polyurethane (PU) paint which can then be directly applied on the substrate and dried easily within 20-30 minutes without evolution of toxic vapors. The two forms of PANI blended with PU were coated on aluminum and mild steel sheets. The corrosion protection performance of the coating was tested using salt spray and immersion techniques. Rate of corrosion was determined by measurement of change in metal weight after the exposure. To produce a good comparison, the corrosion study was performed on both polymer-coated and uncoated metal samples. It was found that PANI-PU coatings can provide considerable protection, as well as a physical barrier against corrosive environments (NaCl) in which the metal are exposed. The corrosion rate for the polymer-coated mild steel and aluminum sheets were significantly lower than the bare sheets. The PANI composites have been found to be promising materials for corrosion prevention

 Abstract

The novelty of this report is synthesis of Bilayer hexagonal disks and hexagonal rings using phytochemicals as reducing agents. Raphanus Raphanistrum( Radish) leaf extract is used as reducing agent and NaOH as stabilizing agent with Zinc Acetate as precursor. A facile synthetic route- Green Hydro thermal method is used for obtaining the structures without any usage of external surfactants. The structural analysis of calcinated ZnO powder is carried out by XRD and the average crystallite size is found to be 21.13nm. The optical properties is checked by UV-VISIBLE spectrophotometer and the band gap is 3.47eV. Presence of functional groups is confirmed by FTIR. Morphology studies is done by SEM and SEM observations confirmed the two different ZnO structures. From size fit analysis, the best fit for experimentation to obtain Nanostructured ZnO is 1.0M- 1800C- 12hrs.

 Abstract

A decomposition of a graph G is a collection ? of edge-disjoint subgraphs H1, H2, � , Hr of G such that every edge of G belongs to exactly one Hi . If each Hi is a path or a cycle in G, then ? is called a path decomposition of G. If each Hi is a path in G, then ? is called an acyclic path decomposition of G. The minimum cardinality of a path decomposition (acyclic path decomposition) of G is called the path decomposition number (acyclic path decomposition number) of G and is denoted by ?a(G). In this paper we investigate some proper acyclic path decomposition number and induced path decomposition number of special types of graphs.

 Abstract

Objective: Quality of life issues have become increasingly important as the number of newly diagnosed patients with cancer increases and survival improves. Brest cancer is the most common type of invasive cancer in Women. The authors carried out a study on 50 newly diagnosed cancer patients with the objective of investigating the changes in anemia profile and how to protect from future risk. Materials and Methods: we conducted a case control study at oncology department of geetanjali medical college and hospital, Udaipur during the period from April, 2016 to February, 2017 and it included a total of 50 newly diagnosed breast cancer patients and 50 healthy controls. Anemia profile (iron, ferritin, TIBC, vitamin B-12) done by cobas-6000 fully automated analyzer. Results: The mean serum level of iron (66.46 � 3.97), ferritin (37.04 � 7.43), TIBC.(323.56 � 26.04) is higher than the control group (29.35 � 1.48), (23.05 � 2.55),(219.28 � 21.93) respectively. The mean vitamin B-12 level in cases (183.64 � 29.38) is lower than the controls (183.64 � 29.38). Conclusions: Our study indicates the significant changes in serum vit- B12, ferritin and iron and TIBC in newly diagnosed breast cancer patients. A significant changes in these parameters will be suggested for further risk of breast cancer in women, so it�s necessary to aware women for the same, so in future can improve their survival.

 Abstract

The population of young people is growing faster in India and the problem of Juvenile delinquency is more acute in society. A child does not just go badly and suddenly without cause. It is a long term process starting from early childhood. Delinquency is a social and psychological problem. The major psycho-social factors are a) Family background, b) Relations in family, c) Intelligence, d) Personality pattern, e) Urban-Rural setting, f) Perceptual pattern, g) Sex differences, h) Effect of mass media, i) Mode of Socializations, j) Psychopathy, k) Working mothers, l) Socio-Cultural impacts, m) Emotional Stability, n) Interpersonal relations and o) Social networking sites and mobiles. The development and growth of adolescents are pivotal for the development of the society and nation at large. To enhance the well-being of the adolescents, intervention strategies are need of the hour. Some vital intervention strategies are 1) Family oriented Interventions, 2) School-based intervention strategies and 3) through NGOs. At present, adolescence needs guidance from the family and community in all aspects. The school environment should also be supportive, non- threatening and safe. Effective acts, policies and programs are very crucial for the development of the youths.

Abstract India is the first country in the world to adopt Family Planning Programme, soon after independence, more than seven decades have been passed since then and the problem of population is still unresolved. Looking at family planning in isolation will be erroneous from analytical point of view. Hence in the following study, an attempt has been made to discuss about a theoretical and conceptual framework which would help in better understanding of the concept, sociologically. The role of gynecologists, role of husband, power relations and women�s autonomy to decide for her body has been analyzed in detail this study.

 Abstract

The wastewater generated from textile industries of Solapur city is studied for its characterization. Wastewater of textile industry was found to contain a high degree of pollutants with high TDS and suspended solids. The wastewater is highly colored and viscous due to dyestuff and suspended solids respectively. Chloride, sulphate, nitrate, Sodium salts of these anions are most commonly used in the process. In heavy metal chromium is in higher concentration while other heavy metals iron, zinc, lead, copper and manganese are also present. The waste water also has high BOD and COD indication its polluting nature. This review collects the general information relating to textile wastewater constituents and organizes it to help researchers who are required to prepare useable water in construction industry. These ingredients are also evaluated based on the typical characteristics of textile wastewater, and special constituents to simulate these characteristics are recommended. The processes carried out during textile manufacturing and the chemicals corresponding to each process are also discussed

 Abstract

The school is a powerful agency in the development of behaviour of the child. It is a miniature of society in which children live, make interactions, get all round development, get socialized and perform mostly function under the supervision of their teachers or instructors. The school is a formal socializing institution which differs from the family. The development of child is influenced by various factors of school like physical development, moral development, emotional development, intelligence level, environment, population, socio economic condition, nutrition, age, type of schools, language, customs, beliefs, rituals, caste, religion, colour and most importantly its social culture & festivals. The present study was undertaken to study the academic stress and academic achievement of government and private secondary school students. The sample of the study comprised of 300 (150 from government and 150 from private) secondary school students which were selected randomly from 12 schools of district Patna, Bihar. For Academic stress, Statements was used and For Academic Achievement, aggregate percentage of marks obtained in previous examination was used for data collection. Results revealed that private secondary school students differ significantly on �Acceptance� dimension of academic achievement while as on composite score both government and private secondary school students differ significantly. Further, private secondary school students showed secondary academic performance rather than government school students.
