27. ASYMPTOTIC SOLUTION OF FOKKER-PLANCK EQUATION BASED ON DARCY-BUCKINGHAM APPROACH IN UNSATURATED SOIL.

Author

Makwana, Pragneshkumar R. and Parikh, Amit K.

Subjects
FOKKER-Planck equation, POWER series, THERMAL conductivity, HYDRAULIC conductivity, ASYMPTOTIC expansions
Abstract

The present study discusses one dimensional groundwater infiltration phenomenon in unsaturated soil. The mathematical formulation is developed using Dracy's law, equation of continuity, and standard relations between diffusivity coefficient and hydraulic conductivity. We solved the obtained system using double power series method in the form of asymptotic expansion which represents moisture content in soil. [ABSTRACT FROM AUTHOR]

46. Structure of N-acetylglucosamine-1-phosphate uridyltransferase (GlmU) from Mycobacterium tuberculosis in a cubic space group.

Abstract

GlmU is a bifunctional enzyme that catalyzes the final two steps in the biosynthesis of UDP-GlcNAc. Crystals of GlmU from Mycobacterium tuberculosis obtained using ammonium sulfate as a precipitant diffracted poorly (to 3.4 Å resolution) and displayed an unusually high solvent content (>80%) with sparse crystal packing that resulted in large solvent channels. With one molecule per asymmetric unit, the monomers from three neighbouring asymmetric units related by the crystal threefold formed a biological trimer. Although this is the first report of the structure of GlmU determined in a cubic crystal form, the trimeric arrangement here is similar to that observed for other GlmU structures determined in hexagonal ( H3, H32, P6322) space groups.

47. Antarctic ice surface properties inferred from Ka and Ku band altimeter waveforms.

Subjects
*PRINCIPAL components analysis, *SURFACE properties, *ANTARCTIC ice, *GRID cells, *ALTIMETERS
Abstract

AbstractAltimetry missions designed for ocean monitoring can also evaluate the Antarctic ice sheet’s mass balance by measuring surface height. However, the returned radar echoes (waveforms) have complex shapes influenced by various snow and ice surface properties at multiple scales. Radar altimeters, operating in different modes and frequencies, interact with these surface properties in diverse ways. In this study, we developed a method to assess Antarctic surface properties using data from SARAL/AltiKa and Sentinel-3A & 3B altimeters for June 2021 and January 2023, respectively. We normalized and averaged the observed waveforms in 5 × 5 km2 grid cells. These were then used to create false-color images, with each grid cell’s average power and time gate represented as different ‘bands’. False-color images were analyzed using Principal Component Analysis (PCA) and ISODATA unsupervised classification to identify regions of Antarctica with similar surface properties. We achieved a percent variance of 73% and 84% for the first three Principal Components (PCs), and 96% and 98% for the first ten PCs with the Sentinel-3 and SARAL/AltiKa datasets, respectively. Finally, we analyzed the Ka and Ku band altimeter waveform shapes for each identified class to better understand snow and ice sensitivity to waveforms. [ABSTRACT FROM AUTHOR]

49. 'India ahead of China in case of ideation'.

Author

Ankur Parikh & Amit Arora

Abstract

Chinese companies have an upper hand in conveying messages to target audience through advertisements, but when it comes to developing content, their Indian counterparts steal the show. "The advertising industry in China is way ahead of its counterpart in India as far as use of technology is concerned. However, India clearly takes the lead when it comes to generating new ideas," says executive director (ED) of Ogilvy & Mather (O&M), Greater China, Kunal Sinha. [ABSTRACT FROM PUBLISHER]
