Density Functionalized Drug-Surfactant Interaction of Aqueous SDS-Tartrazine

Study of molecular density theory is considered nowadays as a powerful tool to speculate various physical and chemical properties of materials. Herein, we report the theoretical inference of associated changes in chemical properties of sodium dodecyl sulphate and tartrazine when allowed to go through pre- and post-micellization phenomena. Because of the involvement of the two compounds in manifold industrial applications, the study reflects some important conclusions of drug-surfactant chemistry. The computational work involves the use of Polarizable Continuum Model (PCM), water as solvent and 631g(d,p) basis set with B3LYP as functional. Each molecule was run individually first to arrive at an optimized structure followed by a final optimization of assumed network (mesh of proposed binary mixture) to visualize the changes that occur on combination. Each set of energy minimal calculation was then run for frequency calculation, electronic spectral evaluation and molecular natural population analysis. Molecular electrostatic potential surfaces were discussed in linking the appropriate hydrophobic and hydrophilic interaction

The direct effect of various photosensitizing salts like NaCl, Na2CO3, and Na2S2O3 on photocatalytic activity of ZnO and Cu0.05Zn0.95O was carefully studied

Eco-management of Wastewater by ZESTP

In present study, an evaluation of ZESTP (Zero Energy Sewage Treatment Plant) has been described as an alternative solution of sewage water treatment. This system has become widely famous because of having great absorption efficiencyof nutrients, simple construction and maintenance, relatively less costly as well as a strong process. After treatment of sewage water, the level of dissolve oxygen was increased up to 73% due to the enhanced numbers of photosynthetic organisms. Some aquatic macrophytes such as Eichhornia crassipes (Mart.) Solms, Pistia stratiotes L. and Hydrilla verticillata Casp were used in ZESTP for waste water treatment based on phytoremediation. ZESTP could reduce the around 84% turbidity, 46% electrical conductivity, 43% salinity, 74% acidity, 69% free CO2, 73% BOD, 44% COD, 70% suspended solids, 62% total hardness, 71% chloride, 59% cadmium, 51% iron, and 71% copper from the waste water. Naturally, some plants have capability are to retain and/or remove fatal chemicals which are present in sewage water. Moreover, macrophytes based ZESTP is a cost effective and an eco-friendly technique of sewage water treatment

Accessibility of Water Among Scheduled Castes in Rural Punjab Issues and Challenges

Access and availability to safe drinking water is not only an important gauge of the socioeconomic status of the household but is also imperative to the health of its members. Efforts have made for high coverage of water in Punjab. In spite of huge progress, the rural water sector still continues to face major challenges. The problem is more acute among Scheduled Castes as only 78 per cent households had drinking water source within the premises in Punjab as per Census 2011. The main objective of the study is to analyses the status and problems of water accessibility among this marginalized section of the society. The present research is based on both Secondary and Primary sources of data collected from SC households in rural Mansa in Punjab. Empirical data was collected through intensive field work using the survey method. Multi-stage sampling technique was adopted. A sample of 200 Scheduled Caste households from 10 villages was selected for the study. The present research unveils that Scheduled castes families face threats to all three prerequisites of an individual’s right to water i.e. there is insufficient water availability, lack of access to water and danger due to water quality, making them easy prey to a number of diseases

Functioning of Village Health Sanitation and Nutrition Committees in Punjab: An Appraisal

The present study aims to assess the composition of VHSNCs; to assess the functioning of VHSNCs and find out the deviations, if any, from the prescribed framework of guidelines and, to understand awareness of VHSNC members about their roles. The proposed study is based on primary data collected with the help of structured questionnaire. The data was collected from one hundred Village Health Sanitation and Nutrition Committees in Punjab. Four districts of the Punjab state were selected randomly from each direction i.e North, South, East and West. The districts selected were Gurdaspur, Mansa, Mohali and Firozpur from North, South, East and West direction respectively. The study reveals that sampled VHSNCs in Punjab have 12 members per VHSNC. One-fourth of the chairpersons of the VHSNCs in Punjab were illiterate Only 23 per cent of the VHSNCs claimed to have prepared the village health plan. Meetings were organized on monthly basis in only half of the expected meetings per VHSNC. Large number of members was not attending the meetings organised by VHSNCs in Punjab. Majority of the funds received by VHSNCs was utilized for sanitation and cleanliness of the village. Majority of members were not aware about the components and objectives of VHSNC. All members reported that the untied fund is always helpful in solving the issues and problems of the village and the amount of untied fund given to VHSNCs should be increased

Applied Perspectives of Environmental Psychology and Wellbeing

Environment is a boon given to each and every living organism on the earth. Being with the nature is always a rich source of mental peace and wellbeing. Connectivity with the nature always gives a sense of being blessed by the Almighty God; it leads to enhance the sense of fully functioning self of the individual as well. Environmental Psychology is an interdisciplinary field which focuses on the application of interaction with environment on the mental, physical, social and spiritual wellbeing. Several research studies have indicated that involvement with natural surroundings is beneficial for the enhancement of overall wellbeing of the society in general and of individuals in particular. Nature is significantly important for the mental health as it helps to reduce the level of stress, irritation, anxiety, aggression, cardiovascular disease etc. The need of the hour is to encourage the health promoting lifestyle which ensures the interaction with the environment in the form of morning walks, meditation, mindfulness, yoga, breathing exercises, cycling, skipping, playing outdoor games etc

Stubble Burning in North-West India and its Impact on Health

Burning of crop residues released many pollutants, resulting in serious health hazards. This paper is an attempt to explore status of crop residues burning in Northwest India and its consequences on health in general and on child health in particular. An effort has also been made to find out the correlation between stubble burning and increasing incidence of acute respiratory infection (ARI) among children in Punjab. Finally an inventory of suggestions to curb this evil has also been prepared. Based on secondary sources, the data collected from various published studies, reports and NFHS, the present study found that residue burning resulted in the emission of greenhouse and various harmful gases. Such emission of harmful gases is many times higher than the standard level of gases as recommended by Central Pollution Control Board (CPCB). It has also been observed that the phenomenon of stubble burning is quite high in Punjab with comparison to other northwest Indian states resulting into increase in incidence of ARI among children
