Urban sustainability, mobility and transportation systems acquire a leading part to guarantee high levels of efficiency and livability of urban and metropolitan systems. Nowadays, railway transport networks represent essential frames to assure accessibility and reduction of traffic pollution and congestion, as well as they provide opportunities for urban regeneration. Recently, in India, railway stations have assumed a strategic role in urban redevelopments to provide efficient and livable urban...

In the proposed project the kraft black liquor obtained from the digestion of Prosopis juliflora hard wood, having concentration of around 12-15%, will be concentrated in an ultrafiltration (UF) process combined with a suitable prior treatment. The reject stream from UF, which is expected to have higher concentration will be fed to a double effect evaporator for further concentration up to more than 50%, and finally to a spray drier. The permeate stream from the UF containing much of alkalies an...

Proteins are molecules that attain a three dimensional structure capable of carrying out diverse functions. Characterization of proteins means to classify or to understand certain key features such as shape,function,reactivity etc. Protein are complex biomolecules and characterization of the newly discovered protein is a challenging task given the nature of the protein,sheer bulk of protein data and limitations of the methodologies available.Analysis of proteins sequences and prediction of terti...

Nanofiltration is gradually evolving from a novel approach into an efficient and eco-friendly unit operation in the arena of separation science and technology. Despite several advantages to its credit, decline in permeate flux or throughput over the period of operation is the major and inevitable drawback of all the pressure driven membrane processes including nanofiltration. This is predominantly attributed to the phenomena of concentration polarization and membrane fouling. Two novel strategie...

Pervaporation (PV) is a promising alternative to conventional distillation technologies in the separation of liquid mixtures for being economical, energy efficient and environmentally benign. Unlike distillation, it can be operated at low temperature to separate close boiling and even azeotropic liquid mixtures without using any entrainer. In PV the feed mixture is in a direct contact with one side of the dense lyophilized membrane whereas permeate (or pervaporate) is removed in a vapor state f...

"Kedar Conical" is selected for the SSIP grant through Gujarat Technological University. It is designed for purification of water. A small-scale photo voltaic and thermal hybrid solar still was designed and developed for getting distilled water. The conical shape of the model makes it the most efficient as it enables the solar radiation from all the direction irrespective of the position of the sun. The heating of water was done by two different means. i.e. By thermal treatment photovoltaic trea...

Ambulatory healthcare monitoring is becoming essential due to the type of lifestyle people are living today. We aim to propose a wearable system for recording the electrocardiogram (ECG) and electroencephalogram (EEG) signals of the subject. It is a convenient option of hospitalization for the patients suffering from various cardiac and neuronal disorders. The cardiac abnormalities like bradycardia, tachycardia, atrial and ventricular fibrillation/flutter and neuronal diseases like epilepsy are ...

The traditional method of machining the hardened steels includes rough turning, heat treatment, and then grinding process. However, in the light of multitude influences of coatings on the contact and tribological phenomena, the choice of coating compound and its structure should be tuned to the specfic tool workpiece combination and process conditions Recently, machining of hard to cut materials using micro coated tools is an emerging technology and an attractive alternative to conventional grin...

The recent trend of digitization and internet of things have made several revolutionizing impacts on human life. Most of the developments and experimental deployments of wireless sensor network are carried out keeping the needs of citizen of towns in view. However, the penchant of researches to share the technology with people in a farming village is amplifying day by day. The aid of wireless sensor network in agriculture field concentrates on providing...

Health diagnosis based of human wrist pulse signals has been in practice since centuries in India, China and other parts of the world. This approach of health diagnosis is based on examination of three wrist pulse palpations over radial arteries. This approach is simple, cheap and non-invasive in nature and has shown successful results for the correct health diagnosis according to ancient Indian Medicine literature formally known as Ayurveda. Identification of appropriate pulse pressure sensors ...

There is huge amount of onion harvesting (approx. 14.1 lakh Metric tonne in year 2008-09 and 153.5 lakh Metric tonne in year 2011-12) done in Gujarat only. Once the onion is harvested from the field, the root and shoot of the onion is to be trimmed which is a labour oriented process. It is estimated that the manpower requirement is around Twelve (12) man days /tonne which is equivalent to 120 man-days/ acre of land assuming an average onion production of 10 tonne/acre of land. Due to the changin...

With the emerging field of nanotechnology, there seems a greater need than ever to be able to carry out computational simulations. This is because the material and devices related to the nanotechnology are often on the atomic scale and thus extremely difficult and costly to fabricate and manipulate. With the availability of highly computational facility and improvements in theoretical method, algorithm and finite element techniques, the capability of simulatio...

Carrying out experiments in the laboratory on various smaller module set?ups are perhaps the best ways of placing the students? understanding of the theoretical basics of the subject on a solid foundation. To that end the modernization of the mass transfer laboratory will be of significant impacts. The Modernization of the laboratory has not only helped remove the obsolescence of the laboratory it would also enrich the practical learning experience of the chemical engineering students thereby e...

Salient features of the project outcome.A novel, cheap and abundantly available agrowaste raw material has been identified for the preparation of activated carbon. A very good quality activated carbon with BET surface area of 595.05 m2g 1, which is much higher than similar types of activated carbons as reported in literature. A novel regeneration technique by the use of microorganism has been developed. The process has immense potential for dephenolation of aqueous waste water streams.Has the po...
