 Abstract

In recent study, there are many researches going on to degrade different organic and inorganic contaminants from the wastewater by doing photocatalytic activity. Nowadays, many photocatalysts are using to degrade pollutants. Many conventional researches are reported about using nanocomposites as a photocatalyst. The photocatalytic oxidation of organic-inorganic compounds with nanocomposites as a photocatalyst has been widely premeditated and many achievements have been made. Many synthesis methods of metal nanocomposites have been reported; therein the sol-gel technology is a simple and accurate method to synthesis very fined and crystalline nanoparticles. It has various and valuable properties like reactivity, high melting point and boiling point, hardness, ductility, electronegative property and ionisation energies, electric and thermal conductivity and closely packed structures, which can be apply in various disciplines of research areas. Nanocomposites are used as a photocatalyst for decomposing organic and inorganic compounds due to its high photocatalytic activity, chemical and physical inertness and photochemical stability and reactivity. In this review paper, the synthesis processes of different metal oxide based nanocomposites have been explained with their different characterisation studies to degrade various pollutants from organic-inorganic compounds. There are diverse arrays of using different nanocomposites to degrade pollutants by using photocatalytic activity.

With the rapid development of mobile games and the roaring growth of market size, mobile game addiction is becoming a public concern. Hence, understanding the reasons behind mobile game addiction is worthwhile. Based on research done so far along with two salient features of mobile games (e.g., hedonic and sociality), a research model is developed to examine the antecedents of mobile game addiction. Therefore, the purpose of this article is to explore the antecedents of mobile game addiction by considering the hedonic and social nature of mobile games. Playing games in order to get flow experiences, this may lead to addiction to mobile games ultimately. On the other hand, some players might not enjoy mobile games but still keep playing to sustain social relationship or gaining social presence. Thus, our model is based on the hedonic and social traits of mobile games.

That the initiation of breast feeding must rank as one of the earliest and most important postpartum decisions made by both the mother and her child in their newly modified, postpartum relationship. Throughout our Health is a fundamental human right. It is central to the concept of quality of life. Health and its maintenance is a major social investment and is a world-wide social goal. Health is multidimensional. This health may be assessed by such indicators as death rate, infant mortality rate and expectation of life. Ideally, each piece of information should be individually useful and when combined should permit a more complete health profile of individuals and communities.1 Breast feeding has been universal and necessary for the survival of the newborn. It is widely recognized that breast feeding has many health benefits both for the newborn and for the mother. Breast feeding not only provides for the fundamental nutritional and emotional needs of the infant, but breast milk provides growth factors, hormones, and maternal antibodies. Breastfeeding is a significant component of this dependency, so species, evolutionary past, and in most contemporary non-industrial settings, at the same time, breastfeeding limits an infant�s exposure to food �borne diseases that may be present with alternative feeding methods.2

 Abstract

Textile wastewater is nowadays a major source of surface water contaminations, where different technologies have been applied for treatment of these carcinogenic effluents. Among the dyes, vat dyes are insoluble in water and are highly stable compared to other dyes. They are used for colouring cellulosic fiber specially cotton fiber. Removal of this vat dye can be a challenging process. Due to the unique physical and chemical characteristics of hydrogels, such as hydrophilicity, swellability and modifiability, there is increasing research interest in the development and application of novel hydrogels in water and wastewater treatment. Hydrogels have exhibited superior performance in the adsorptive removal of a wide range of aqueous pollutants including heavy metals, nutrients, and toxic dyes. Chitosan and guargum are among the world�s most abundant and low-cost biopolymers that is natural, renewable, environmentally benign, cost-efficient, nontoxic, biodegradable, and biocompatible. Chitosan guargum based hydrogels were found to be very effective in the removal of Vat Orange 3G dye. The effect of various parameters such as pH and contact time on the adsorption process by the hydrogel was studied with synthetic wastewater. The effect of pH was studied initially by batch experiments and found that better efficiency in dye removal was at a lower pH of 4. The study on effect of time showed an increase in percentage removal with increase in time and reached a maximum value of 85% within 2 hrs. From the adsorption kinetics study it was found that the adsorption process by the chitosan guargum hydrogel followed pseudo second order kinetics. Thus chitosan guargum based hydrogels is a promising technology in the removal of vat dye which is an ecofriendly method.

 Abstract

Today India is turning towards a new era, that of web series. These web series seem almost tailor-made for the younger generation of Indians, who practically live on the internet. What possibly guarantees brownie points for these series is the fact that its creators have webbed stories centring around the everyday Indian. Gone are the days of protagonists sporting heavy make-up and heavier ancestral jewellery for each scene. The flamboyance has toned down to flannel shirts and flip-flops coupled with casual �Hinglish� and 21st century �modernity�. Through dark humour and intelligent scripting, the writers of the series have decided to tap into the everyday problems of the ordinary middle to upper-middle class Indians. Additionally, the characters are quite grounded and ordinary in contrast to the overtly moralistic �bahu� and the �evil saas� of the K-serials. Viewers can relate to this new generation of protagonists and their stories without a blink of the eye.

 Abstract

The country's economy highly depends on its agricultural productivity That is why disease detection in plants plays a significant role in the agriculture field as having a disease in plants are quite normal. If we don't take good care of this, then it will cause serious effects on plants and due to which respective product quality, quantity or productivity is affected. This paper presents a way for early detection of leaf diseases in plants based on some vital features extracted from its leaf images. In the proposed system, the image of leaves is captured and compared with images in the database of the leaves that are pre-stored in the device memory. This detection may be resolved by laboratory analysis, however this a process that is often time-consuming and expensive.
