A reliable aging-prediction method is significant for lithium-ion batteries (LIBs) to prolong the service life and increase efficiency of operation. In this paper, an improved Gaussian-process regression (GPR) proposed predict degradation rate LIBs under coupled aging stress simulate working conditions. The complicated processes at different ranges state charge (SOC) discharge rates were analyz...

The presence of alloying elements, sometimes in a very small amount, affects mechanical properties one of these elements is Boron. In Aluminum industries, Boron master alloy is widely used as a grain refiner In this research, the production process of Aluminum –Boron master alloy was studied at first then, it was concurrently added to 2024 Aluminum alloy. After rolling and homogenizing the resu...

use of plant growth promoting bacteria (pgpb) and high quality of seed as agricultural inputs play important roles in sustainable crop production. to study the effects of different levels of seed aging and pgpb's application on field emergence, seedling establishment and yield of two red kidney bean cultivars in field conditions, an experiment was carried out as factorial based in a rcbd d...

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...

introduction: prior studies comparing hemodynamic response function (hrf) in the young and elderly adults based on fmri data have reported inconsistent findings for brain vision and motor regions in healthy aging. it is shown that the averaging method employed in all previous works has caused this inconsistency. the averaging is so sensitive to outliers and noise. however, fmri data are obscure...

the most popular animal models of alzheimer’s disease (ad) are transgenic mice expressing human genes with known mutations which do not represent the most abundant sporadic form of the disease. an increasing number of genetic, vascular and psychosocial data strongly support that the octodon degus, a moderate-sized and diurnal precocial rodent, provides a naturalistic model for the study of the ...

background: oleuropein is a phenolic compound which is present in the olive leaf extract. the purpose of the present study was to investigate the neuroprotective effect of oleuropein as an antioxidant agent on the substantia nigra in aged rats. methods: twenty 18-month-old wistar rats (450-550 g) were randomly divided into control and experimental groups. the experimental group received a daily...

conclusions the mathematical meaning of the two insulin-related biomarkers examined was the same, and the odds ratios of the two biomarkers were almost the same after adjustments for other independent variables. objectives a one-year follow-up study was conducted to determine the ability of the insulin-related biomarkers to predict the risk of mets development. patients and methods a total of 2...
