Buckling of thin-shell structures is one the most canonical problems in mechanics. In practice, buckling load and its deviation from theoretical prediction often handled through development knock-down factors shell structure design. Uncertainty-informed analysis based design an alternative path that has been aggressively pursued recent years. this study, we use a novel representation stochastic...
In order to detect knock in spark plug engines generally structure–borne sound signals measured by acceleration sensors mounted on the engine housing are used. At test bed engines additional pressure sensors measuring the pressure inside the combustion chamber deliver a reference signal to adjust the parameters of knock detection based on the sound signal. We show by experimental results that t...
Glutathione peroxidase (GSHPx) is a critical intracellular enzyme involved in detoxification of hydrogen peroxide (H(2)O(2)) to water. In the present study we examined the susceptibility of mice with a disruption of the glutathione peroxidase gene to the neurotoxic effects of malonate, 3-nitropropionic acid (3-NP), and 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP). Glutathione peroxidase ...
French literature has shown an enduring fascination with the social figure of the doctor. In Jules Romains' amusing play Knock (1922), and in its later film version (1951), the doctor as deceiver returns to centrestage with a flourish. Molière's seventeenth-century figures were mostly quacks and mountebanks; Knock is something new: he is a health messiah. By enforcing a mental and social hygien...
This paper studies the effect of nitric oxide (NO) on the onset of knock in a cooperative fuel research (CFR) engine. The experiments are conducted at both the standard knock intensity (SKI) condition for research octane number (RON) tests, as well as at a richer operating condition of a similar knock intensity but a higher compression ratio. Iso-octane is the fuel. The experiments show clearly...
Vesicular (v)- and target (t)-SNARE proteins assemble in SNARE complex to mediate membrane fusion. Tetanus neurotoxin-insensitive vesicular-associated membrane protein (TI-VAMP/VAMP7), a vesicular SNARE expressed in several cell types including neurons, was previously shown to play a major role in exocytosis involved in neurite growth in cultured neurons. Here we generated a complete constituti...
Cytochrome P450 4x1 (Cyp4x1) is expressed at very high levels in the brain but the function of this protein is unknown. It has been hypothesised to regulate metabolism of fatty acids and to affect the activity of endocannabinoid signalling systems, which are known to influence appetite and energy metabolism. The objective of the present investigation was to determine the impact of Cyp4x1 on bod...
The molecular mechanism underlying renal hypertrophy and progressive nephron damage remains poorly understood. Here we generated congenic ribosomal protein S6 (rpS6) knock-in mice expressing nonphosphorylatable rpS6 and found that uninephrectomy-induced renal hypertrophy was significantly blunted in these knock-in mice. Uninephrectomy-induced increases in cyclin D1 and decreases in cyclin E in ...
prediction of hydrological variables is a highly effective tool in water resource management. One of the important tools for modeling hydrological processes is the use of time series modeling and analysis. River series production series can be used by time series models in various studies such as drought, flood, reservoir systems design and many other purposes For this purpose, monthly flow dat...
