Synthesis and Characterisation of Metallic Coating by Pulsed DC

Metallic coating is given to provide a layer of protection to metals or other types of materials that are subjected to various harsh operating conditions like high temperature, contact surfaces, corrosive media, high stress and other surface degrading conditions. These coatings help to enhance the reliability and performance of industrial. These coatings are used in industries such as aerospace, defense, military and automotive. Some of the most common metallic coatings that can be applied to substrate are Zn, Cu, Cd, Ni, Zn and Au. In this project Nickel coating was given to mild steel substrate as Nickel gives a anti corrosive coating to the steel surface and also enhances the hardness value of the surface. Nickel is now extensively used in industrial applications for Decorative as well as Engineering purposes because of its bright appearance and resistance to corrosion property. Nickel deposition was carried out using Watts Bath and deposition was carried out by electrodeposition method. Electrodeposition is the fastest and simplest method of providing coating to any substance. Deposit characteristic can be modified by changing various operating parameters like current density, temperature and pH of the solution. Use of pulse DC gives more control over the microstructure and morphology of deposit. Ten different samples were given coating, one used as reference sample was given coating in presence of DC and others using pulsed DC. In case of pulse DC three different parameters can be varied to give different features to deposit namely peak current, TON and TOFF. Finer grains can be obtained using pulse DC. After the deposition completed, the coating was characterizes by XRD, SEM and hardness measurement

SOLID WASTE MANAGEMENT IN KANPUR CITY, INDIA, A DEVELOPING COUNTRY

The purpose of this research is to define the existing state of municipal solid waste (MSW) in Kanpur city to identify the main obstacles its efficiency and the prospects for improvisation of the solid waste management system in the city. The usual approach to problem solving is to survey previous work done in this subject area of solid waste management. Various studies say that 95% of MSW is disposed of unscientifically in open dumps and landfills, creating problems to public health and the environment. The amounts of waste generation have been increasing in India with increasing urbanization. Since higher education campuses about 90% are such as autonomous cities, they can act as a model for solid waste management (SWM) and enhance sustainable development. SWM is the controlled generation, storage, transport, processing, and disposal of solid waste considering public health, conservation, economics, and environmental conditions. Many developing countries such as India are lacking behind in SWM from the developed countries which are using advanced technologies along with efficient management. This paper will analyze the issues related to SWM Kanpur streets for becoming zero waste streets. Lack of awareness and improper collection, exposed transportation, inefficient processing, and disorganized disposal of solid waste are the major reasons for it. Some techniques would reduce the amount of waste diverted to landfills and the problems arising on streets due to solid waste, thus leading to zero waste streets. This paper identifies a need to implement a robust SWM at the Kanpur city in India

POTENTIAL ANTI-CANCER SUPERFOODS: A MINIREVIEW

Cancer, a leading cause of mortality worldwide, has gained much attention and concern for its debilitating effects. Among the various oncological treatments and therapies like surgery, radiation, hormonal therapy, immune therapy, targeted therapy, Chemoprevention or Chemotherapy has recently being recognized as a promising strategy for prevention of afflicting disease like cancer. Chemoprevention is the use of natural or synthetic agents (alone or in combination) to suppress or prevent the process of oncogenesis. The role of diet and nutrition in cancer development has been overlooked for decades, despite of its strong scientific evidence. Only in recent years, plants, vegetables, herbs and spices of traditional diet and medicines have been accepted as one of the main sources of chemo preventive substances

EFFECT OF ZEIN ON CIPROFLOXACIN FLOATING TABLETS

Objective: This work was aimed to formulate and evaluate the effect of zein on Ciprofloxacin HCl floating tablets. According to previous studies, it was set up to be useful against bacteria i.e. Helicobacter pylori which leads to peptic ulcers. Thus, it is quite necessary to enhance the Gastric Retention Time for similar medicines. Methods: 12 different floating tablets of Ciprofloxacin HCl were formulated with wet granulation method with a rise in the concentration of zein. Further, all different formulations prepared were evaluated for different parameters i.e. pre-compression considerations, along with post-compression factors like weight variation, content uniformity, thickness, visual assessment, hardness, friability, buoyancy studies i.e. total floating time as well as floating lag time, swelling index, dissolution and drug release kinetics. Results: The F6 formulation was considered to be among finest formulation with appropriate hardness. It was found that with the increasing concentration of zein, the hardness of tablets was also increased. It showed TFT of more than 7 h, FLT of 310 sec, a swelling index time of 99.5 % in 4 hr, while drug release kinetics was found to follow Higuchi Model. Conclusion: Overall it was also found that HPMCK-100M is more effective as compared to HPMC-K15M and Zein has a major role in increasing the hardness of tablets. In the future, the investigation will be continued with the following studies: An in vivo study and a long-term stability study

Association of new-born birth weight with maternal parameters

 Background: Birth weight is the single largest determinant of the neonatal survival and wellbeing. Maternal anaemia is the commonest medical disorder in pregnancy and is associated with significant maternal morbidity and mortality. The effect of haemoglobin levels of the mother on the foetus however remains unclear. This study aims at evaluating the effect of maternal anaemia on neonatal birth weight. It also evaluates the effect of parity, gestational age and maternal age on the new-born birth weight.Methods: A retrospective study was carried out on patients who had delivered in Al Falah hospital, a newly setup medical college in rural Haryana. The population was studied for maternal age, gestational period, and parity and haemoglobin levels. These parameters were correlated with neonatal birth weight. The study was carried out on deliveries which occurred over a period of six months from November 2018 to April 2019.Results: The low birth weight new-borns were 10.5%. Maternal anaemia was present in 79.74 % of women in the study group. Amongst all parameters studied, only higher parity and greater period of gestation had a positive correlation with neonatal birth weight. Haemoglobin levels or maternal age didn’t show a significant impact on the neonatal birth weight. Anaemic mothers didn’t have a higher incidence of low birth weight babies.Conclusion: The most significant contributor to improved neonatal weight is the gestational age of the foetus. All efforts to ensure better neonatal outcome must primarily concentrate on prevention of preterm births. Maternal haemoglobin levels do not directly impact the neonatal birth weight. However, as anaemia is a risk factor for preterm delivery, anaemia indirectly impacts on the neonatal birth weight and outcome

Development of E Waste based Composite Microwave Absorbing Material

Microwave absorbing materials (MAMs) are widely researched due to their use in many practical applications including both civil and defense sectors. Irrespective of the humongous efforts of various researchers, the development of a wide bandwidth, thin coating thickness, and low-cost microwave absorber is still a challenging task. The existing materials have not been able to meet all the specifications together at once and require a trade-off in the performance parameters. In this paper, we have empirically corroborated a cost-effective technique using E-waste material for synthesising composite MAM. It is herein shown that the addition of different wt% of copper, graphite, and titanium dioxide in the E-waste successfully resulted in enhanced absorption due to altered electrical properties of the E-waste suitable for microwave absorption. The multilayering technique with the help of a genetic algorithm has also been used to broaden the bandwidth. As a result, a three-layer MAM with the total coating thickness of 3.2 mm has been synthesised showing the wideband absorption bandwidth of 8.47 GHz in the frequency range from 6.92 to 15.39 GHz. The results suggested that microwave absorption of E-waste can be drastically improved by appropriately tailoring electrical parameters such as permittivity and permeability
