Abstract: The scale dependence of the strength of virtually homogeneous rock is usually considered to be insignificant but the spectrum of discontinuities plays a very important role for the strength of differently sized rock elements and also controls the rock creep strain. Large-scale load tests comprised recording of the creep strain rate that was found to be strongly retarded and negligible for stresses lower than about 1/3 of the failure load. For higher stresses creep took place according to a log time law representing secondary creep that ultimately changed to tertiary creep and failure.
Abstract: MMR vaccine failure had been reported globally and
here we report that it occurs now in India. Samples were collected from clinically suspected mumps cases were subjected for anti
mumps antibodies, virus isolation, RT-PCR, sequencing and
phylogenetic tree analysis. 56 samples collected from men and women belonging to various age groups. 30 had been vaccinated and
the status of 26 patients was unknown. 28 out of 30 samples were
found to be symptomatic and positive for Mumps IgM, indicating
active mumps infection in 93.4% of the vaccinated population. A
phylogenetic tree comparison of the clinical isolate is shown to be genotype C which is distinct from vaccine strain. Our study clearly sending warning signs that MMR vaccine is a failure and it needs to be revamped for the human use by increasing its efficacy and efficiency.
Abstract: Chemically defined Schlegel-s medium was modified
to improve production of cell growth and other metabolites that are
produced by fluorescent pseudomonad R62 strain. The modified
medium does not require pH control as pH changes are kept within ±
0.2 units of the initial pH 7.1 during fermentation. The siderophore
production was optimized for the fluorescent pseudomonad strain in
the modified medium containing 1% glycerol as a major carbon
source supplemented with 0.05% succinic acid and 0.5% Ltryptophan.
Indole-3 acetic acid (IAA) production was higher when
L-tryptophan was used at 0.5%. The 2,4- diacetylphloroglucinol
(DAPG) was higher with amended three trace elements in medium.
The optimized medium produced 2.28 g/l of dry cell mass and 900
mg/l of siderophore at the end of 36 h cultivation, while the
production levels of IAA and DAPG were 65 mg/l and 81 mg/l
respectively at the end of 48 h cultivation.
