Opis:
Mung bean or moong or green gram, an important grain legume, is cultivated mainly in Asian countries and other parts of the world as a food crop. It is a highly nutritious grain legume with a high content of easily digestible proteins (20–32%), carbohydrates (53.3–67.1%), lipids (0.71–1.85%), vitamins, minerals, and fiber. It also contains some antinutrients such as tannins, phytic acid, hemagglutinin, polyphenols, and trypsin inhibitors in low concentrations. The sprouting of seeds leads to dynamic changes in metabolites with a decrease in antinutrient content and an increase in the nutritional value. In addition to these nutrients and antinutrients, the plant also contains various other phytochemicals such as alkaloids, flavonoids, saponins, phenols, glycosides, and bioactive peptides, which exhibit an array of pharmaceutically important properties such as anti-inflammatory, antinociceptive, antimicrobial, antioxidant, antidiabetic, lipid metabolism regulation, antihypertensive, antiallergic, and antitumor. Being rich in nutritional value and other phytochemical components, the plant can be explored further for its pharmaceutical properties and used as an efficient food additive in the preparation of different types of dietary supplements or food-derived drugs.

Urban Transportation
Opis:
Urban areas and metros are growing at a much higher rate than the rural areas. Urban areas play a significant role in the development of the nation by contributing 60% of the national income with only 27.78% of the population. Urban Transport is the most crucial (infrastructure) element in shaping urban development and living. The supply of transport is heterogeneous with a number of interacting and competing modes while the demand for it is derived from the overall pattern of urban activity. Urban Transport has a significant impact on the environment, land use, and land development patterns. In India, multiple institutions are responsible for urban transport and it is governed by multiple policies/ Acts/ legislations. While bus is the major mode of urban transport, local/suburban trains (Railway), Taxies/Autos and personalized transport makeup the rest. Lack of proper public transport has resulted in the increase of personal vehicles, causing problems of congestion, pollution and loss of productive time on travel delays. Study of urban transport systems across the world has revealed that well coordinated institutions with dedicated funding sources and proper planning ensure well functioning urban public transport systems, keeping the cities liveable and productive. Urban transport has to be a public good and be funded through public resources. Indian context have revealed a good beginning made in this direction but absence of institutional arrangements for planning at local level, lack of coordination among various institutions and departments, lack of dedicated funding, lack of inter modal coordination, lack of patronage for new rail based systems are also glaring.

Opis:
Onion slices were dehydrated under vacuum to produce good quality dried ready-to-use onion slices. Colour development due to non-enzymatic browning and flavour loss in terms of thiosulphinate concentration was determined, along with moisture content and rehydration ratio. Kinetics of non-enzyma-tic browning and thiosulphinate loss during drying was analysed. Colour change due to non-enzymatic browning was found to be much lower in the case of vacuum dried onion, and improved flavour retention was observed as compared to hot air dried onion slices. The optical index values for non-enzymatic browning varied from 18.41 to 38.68 for untreated onion slices and from 16.73 to 36.51 for treated slices, whereas thiosulphinate concentration in the case of untreated onion slices was within the range of 2.96-3.92 μmol g-1 for dried sample and 3.71-4.43 μmol g-1 for the treated onion slices. Rehydration ratio was also increased, which may be attributed to a better porous structure attained due to vacuum drying. The treatment applied was found very suitable in controlling non-enzymatic browning and flavour loss during drying, besides increasing rehydration ratio. Hence, high quality dried ready- to-use onion slices were prepared.

Opis:
The perovskite lithium lanthanum titanate shows high ionic conductivity at room temperature. Doping the lithium lanthanum titanate by niobium preserves the perovskite structure, which is synthesized by ceramic technology at high temperature (1300°C). The X-ray diffraction and scanning electron microscopy results show that the samples exhibit single phase. AC impedance measurements indicate total conductivity of about $8.93 \times 10^{-4}$ S/cm for composition of x = 0.05 at room temperature. The Raman spectra and cyclic voltammetry results of the compound are also reported.

Opis:
This paper presents the review concerning mechanical properties of bone and the miniature specimen test techniques. For developing a realistic understanding of how factors such as moisture content, mineralization, age, species, location, gender, rate of deformation etc. affect the mechanical properties of bone, it is critical to understand the role of these factors. A general survey on existing research work is presented on this aspect. The essential features of miniature specimen test techniques are described, along with the application of small punch test method to evaluate the mechanical behavior of materials. The procedure for the determination of tensile and fracture properties, such as: yield strength, ultimate strength, ductility, fracture toughness etc. using small punch test technique have been described. The empirical equations proposed by various investigators for the prediction of tensile and fracture properties are presented and discussed. In some cases, the predictions of material properties have been essentially made through the finite element simulation. The finite element simulation of miniature specimen test technique is also covered in this review. The use of inverse finite element procedure for the prediction of uniaxial tensile constitutive behaviour of materials is also presented.

Opis:
A Kelvin-Voigt model consisting of a spring and a dashpot in parallel was applied for the viscoelastic characterization of solid rocket propellants. Suitable values of spring constants and damping coefficients were employed by a least squares fit of the errors to generate creep curves using a Dynamic Mechanical Analyzer (DMA) for composite solid propellants. Three different composite propellant formulations based on HTPB/AP/Al having burning rates of 5 mm/s, 15 mm/s and 20 mm/s were tested under different stress levels varying from 0.1 MPa to 3 MPa and at different temperatures varying from 35 °C to 85 °C. Creep behavior with recovery was studied and analyzed to evaluate the viscoelastic properties. The change in spring constants, representing elastic deformation, was very small compared to the damping coefficients for the propellants studied. For a typical propellant formulation, when the stress level was increased, the spring and damping coefficient both increased significantly whereas for an increase in temperature, they remained nearly constant. However, the ratio E/η was observed to be constant and independent of stress level. It was also observed that the variation of E and η varied linearly with increase in stress whereas their ratio showed a logarithmic variation. A mathematical correlation was developed to evaluate the viscoelastic properties during creep of composite propellants.

Opis:
At present speed ranges for Levels of Service (LOS) categories are not well defined for highly heterogeneous traffic flow on urban streets in Indian context. In this regard a study was carried out in the city of Mumbai in India. The objective of this research work is to define free-flow speed ranges of urban street classes and speed ranges of LOS categories. In this regard speed data were collected using GPS palmtop and Fuzzy C-Means (FCM) clustering is used to define the speed ranges. It is found from this study that speed-ranges for LOS categories in Indian context are lower than that mentioned in Highway Capacity Manual.
