Studies On The Mechanisms Involved In Thymic Atrophy During Salmonella Enterica Serovar Typhimurium Infection
(2015-09-04)T lymphocytes are an essential component of the adaptive immune response and are highly versatile in function. Each T cell has a unique T cell receptor that can recognize an antigenic peptide in the context of the major ... -
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ... -
Studies on the Modeling of Fatigue Crack Growth and Damage in Concrete : A Thermodynamic Approach
(2018-01-11)Fatigue in concrete is a complex phenomenon involving formation of microcracks, their coalescence into major crack and simultaneous formation of the fracture process zone ahead of the crack tip. Complex phenomena are best ... -
Studies On The Molecular Mechanism Of Cytokinin Action: Involvement Of Ca2+, Protein Kinase And Concurrent Protein Synthesis In Signaling Of Cytokinin-Induced Expression Of Pathogenesis-Related Enzymes In Cucumber
(Indian Institute of Science, 2005-12-08)Phytohormones act as signals to regulate plant growth and development by modulation of gene expression in response to internal developmental cues or external environmental stimuli, such as light and pathogen infection. ... -
Studies On The Phenomenon Of Blastocyst Hatching: Role Of Cysteine Proteases
(2007-11-16)The mammalian embryo is encased in a glycoproteinaceous covering, the zona pellucida (ZP/zona) during preimplantation development. Prior to implantation into the recipient maternal endometrium, the blastocyst has to hatch ... -
