The research focuses on the multi-objective single-machine static scheduling problems of motorcycle crankcase cover. To solve these problems, dispatching rules are used. Various used in this study earliest due date (EDD), shortest processing time (SPT), critical ratio (CR), longest (LPT), weightage (WSPT), cost over (COVERT), and hodgson’s algorithm. objective paper is to sequence different cov...

Inhibition of mammalian target of rapamycin, mTOR, extends lifespan and reduces age-related disease. It is not known what role mTOR plays in the arterial aging phenotype or if mTOR inhibition by dietary rapamycin ameliorates age-related arterial dysfunction. To explore this, young (3.8 ± 0.6 months) and old (30.3 ± 0.2 months) male B6D2F1 mice were fed a rapamycin supplemented or control diet f...

The Palatini gravitational action is enlarged by an arbitrary function $f(X)$ of the determinants Ricci tensor and metric, $X=|\textbf{det}.R|/|\textbf{det}.g|$. resulting Ricci-determinant theory exhibits novel deviations from general relativity. We study a particular realization where extension characterized square-root Ricci-determinant, $f(X)=\lambda_\text{Edd}\sqrt{X}$, which corresponds t...

Ab-initio electronic structure methods are used to explore potential energy profiles pertinent to the fragmentations of gas-phase radicals thought to be formed in the new negative-ion mode EDD mass spectroscopic studies of peptides. Barriers to fragmentation as well as the associated overall energy differences are computed for the observed Calpha-C backbone bond cleavage as well as for side-cha...

Walls and frames have different deflection lines and, depending on the seismic mass they support, may often possess different natural periods. In many cases, wall–frame structures present an advantageous behavior. In these structures, the walls and the frames are rigidly connected. Nevertheless, if the walls and the frames were not rigidly connected, an opportunity for an efficient passive cont...

We present a comprehensive study of GRS 1915+105 in wide energy band ($0.5-60$ keV) using AstroSat observations during the period $2016-2019$. The MAXI X-ray lightcurve source shows rise and decay profiles similar to canonical outbursting black holes. However, does not follow exemplary 'q'-diagram Hardness-Intensity Diagram (HID). Model independent analysis lightcurves suggests that displays va...
