 Abstract

The natural dyes are increasing the awareness among all peoples. Natural dyes are used because of their best nontoxic properties and it is eco-friendly in nature. Some natural dyes have its own medicinal value and it gives more benefits to human as well as environment. This study deals with the natural dye, and it was extracted from the shell of Juglans Regia (Walnut). Here, the aqueous extraction method was followed to extract the dye from walnut. The dye from the Juglans Regia (Walnut) is giving a beautiful earthen shades and it has excellent dyeability in the cotton fabric. The extracted dye was applied on the cotton fabric with and without mordant. Three types of mordants are used to get a different shade of colours. Thickness, colourfastness and absorbency tests were taken in all the dyed and undyed samples.

 Abstract

Water pollution is one of the key studies that has drawn the attention of academics and people interested in the environment due to its enormous impact on the lives of humans, animals, and plants alike. It is not less dangerous than air and soil pollution, but it is more intimately related to both. The research focused on the concept of pollution in general, followed by the concept of water contamination and its origins. In addition to groundwater contamination, several pollution processes have occurred, the most significant of which are biological, physical, and through dumping solid and liquid waste into rivers, lakes, and oceans.

 Abstract

Background: Cardiac papillary fibroelastomas are considered the second most common benign primary cardiac tumor after myxoma. Case summary: The clinical presentation of these tumours varies from asymptomatic to severe ischaemic or embolic complications. The patient presented with left hemiplegia and dysarthria, and as part of its etiological assessment a transesophageal ultrasound was performed objectifying papillary fibroelastoma of the aortic valve arising from the endocardium of the left coronary cusp. The diagnosis was clarified by the other imaging systems (scanner and magnetic resonance imaging). In front of the embolic episode and the size of the fibroelastoma, the patient was operated, and recovered well. Conclusion: This case contributes to highlighting that cardiac papillary fibroelastomas are a rare but potentially significant cause of cardioembolic stroke. Urgent resection of the tumour is not only life saving but also avoids tumour related vascular, embolic or neurological complications.

 Abstract

The paper deals with mineral analysis of leaves of Pongamia pinnata Linn. Merr infected with Fusicladium effusum fungus causing brown spot disease. The dried leaf samples of infected and healthy were subjected to tri acid digestion, prescribed by Toth et al.,(1948). The acid digested sample were used for analysis of mineral elements by Atomic Absorption Spectrophotometer ( CHEM BIOTECH, MODEL- CB-AAS-3510) , Visible Spectrophotometer (CHEM BIOTECH, Model CB-104) and Flame photometer (Labotronics Model LT-671. The elements such as Potassium, Calcium and Sodium were estimated by Flame photometer, while phosphorous estimated by Sekine et al.,(1966) method, and sulphur element were determined by Blanchar et al., (1965) method. The elements such as Sodium, Calcium, Zinc, Iron and Phosphorous were enhanced in infected leaves, where as Potassium, Copper, Manganese and Sulphur were decreased in the infected leaves, expresses a high metabolic shift.

 Abstract

Today Automobiles have become the main part of regular life. Based on the demand the usage of vehicles has been increased in this urban life. Transportation carbon emission is a significant contributor to the increase of greenhouse gases, which directly threatens the change of climate and human health. Under the pressure of the environment, it is very important to measure transportation carbon emissions on a real-time basis. We get the transportation carbon emission information by calculating the combustion of fossil fuel in the transportation sector. In this paper, we predict the vehicle's real-time carbon emission using an MQ2 Gas sensor based on the Support Vector Machine (SVM) algorithm to observe datasets in the city, and the GPS data helps to locate the vehicle's current location. An initial warning is given to the driver regarding the amount of CO2 gas with the help of an LCD, buzzer, and later the same information is transferred to the Police Control Room in case of negligence. Here the hardware (carbon emission sensor) device which connected to the android application, and the application sends the data to the cloud server (RTO) through the Global System of Mobile Communication (GSM). When there is an excess amount of CO2 release from the vehicle, an alert message is sent to the vehicle owner.

 Abstract

This study was carried out in various government schools of Bilat Circle, East Siang district, Arunachal Pradesh, to know about the status of RTE, after almost a decade of its implementation. The main objective of the study was to determine the implementation Status of the various provisions of RTE Act in relation to adequate infrastructure facilities, status of teachers, SMC, Mid day meal, free textbook and uniform. The main sources of data were interviews, questionnaires and schedule. The study throw light into the poor condition of elementary education and reveals that there is an acute shortage of even the basic infrastructure facilities, lack of subject expert, lack of awareness among parents and among the SMC members. Overall condition of primary education in Bilat Circle is quite deplorable and there is serious need to reconsider the whole education education system and to monitor the program running for school going children. The successful implementation of programs, serious monitoring and an effective information system is the need of the hour.

 Abstract

Disasters occur on a daily basis all around the world. People in affected areas look for a secure place to stay during a calamity. The majority of people flee to a shelters, which is a public safe area that is generally organized and sponsored by the government. The primary priority of affected persons is the providing of shelter, as with shelter comes other essentials such as sanitation and food. Temporary structure will provide to the individuals who are affected by disasters with safety and security until their permanent homes are repair. As a result, while designing and planning temporary shelter, various factors should be considered, such as the location of the temporary structure, the availability of materials and expertise, and the physically and mentally requirements of affected individuals. After various design changes are given to the affected individuals, a complete evaluation of existing shelters is done to assess their quality of life. The research was conducted using a set of criteria that included the temporary shelter solution to an emergency.

 Abstract

Abstract The role of nanomaterials in the development of biocomposites is very crucial. It has been seen in the studies that it has been creating huge impact on the properties of biocomposites material. In field of material science enormous research work has been taking place to develop eco-friendly efficient biocomposites material. The industrial sustainability, eco-efficiency, and green chemistry are guiding principles for the development of the next generation products and processes. Considerable growth has been seen in the use of biocomposites material in the domestic sector, building materials, aerospace industry, circuit boards, and automotive applications over the past decade, but application in other sectors until now has been limited. Nevertheless, with suitable development, the potential exists for biocomposites to enter new markets and thus stimulate an increase in demand. Many types of natural fibers have been investigated with polymer matrices to produce composite materials that are competitive with synthetic fiber composites which require special attention. The Nanomaterials can be used to prepare fiber-reinforced polymer composites for commercial use and have marketing appeal. The growing global environmental and social concern, depletion of petroleum based resources, and new environmental regulations have forced the search for new biocomposites, compatible with the environment. Many references to the current status of research work on the impact of nanomaterials and applications of biocomposites are cited in this review.
