Endoplasmic reticulum (ER) stress, unfolded protein response (UPR), and mitochondrial biogenesis were assessed following varying intensities of exercise training. The animals randomly assigned to receive either low- (LIT, n=7) or high intensity training (HIT, n=7), a control group (n=7). Over 5 weeks, the in LIT exercised on treadmill with 10° incline for 60 min at speed 20 m/min group, HIT 34 days week. No statistically significant differences found body weight, plasma triglyceride, total...

Alcohol consumption leads to the dysfunction of multiple organs including liver, heart, and skeletal muscle. effects on insulin resistance in liver are well evidenced, whereas its muscle remain controversial. Emerging evidence indicates that alcohol promotes adipose tissue dysfunction, which may induce organ dysregulation. We show ethanol (EtOH) reduces activation 5'AMP-activated protein kinase (AMPK) mammalian target rapamycin (mTOR) as carnitine palmitoyltransferase 1 (CPT1) glucose...

Abstract This work presents the comparative study of linear tubular permanent magnet motor (LTPMM) for active suspension system in vehicles. To analyse and design LTPMM, a finite element‐based optimisation process is proposed. Since proposed method reconstructs entire field by storing information air‐gap magnetic flux distribution form snapshot, it provides high accuracy reduced computation time. The fields are analysed LTPMMs with external internal magnets that classified according to...

Conventional radiosondes can be used to measure the relative humidity over liquid (RHL) by assuming a saturated vapor pressure liquid. However, this assumption results in significant errors with respect measurements upper troposphere, where effect of ice is dominant. Therefore, study presents novel method that considers effects determine from radiosonde RHL data for last 40 years (1979–2018) layers Korean peninsula. Even though obtained reanalysis was significantly different radiosonde-based...

A conventional unloading analysis was carried out in no consideration for fast lateral velocity and disk rpm drop during the emergency parking. However, current hard drive (HDD) systems need an improved performance portable aspect. Therefore, much faster parking is absolutely necessary to protect system from sudden power-off or external shock. In case of parking, causes effective skew, then there a flying height (FH) loss which does not occur normal unload. Also, FH induced by occurs at...

Several developed countries have recently provided electric vehicle consumers and producers with financial subsidies. There has been some empirical research on the impact of government subsidies consumers' purchase cars. However, little analytical for car market exists. This analyzes price technology level as well adoption also suggests that should subsidize only to further improve technology.
