INVESTIGATION OF FILM THICKNESS OF GREASE-LUBRICATED THRUST BEARING: FROM BALL-ON-DISC TO BEARING [PDF]

open access: yesProceedings on Engineering Sciences, 2019
Rolling element bearings lubricated by greases represent the most used mechanical components in industry, thus the total volume of energy required to overcome their friction is enormous. Even small improvements can provide considerable savings.

Identification of the cDNA Encoding the Growth Hormone Receptor (GHR) and the Regulation of GHR and IGF-I Gene Expression by Nutritional Status in Reeves’ Turtle (Chinemys reevesii)

open access: yesFrontiers in Genetics, 2020
Chinemys reevesii (Reeves’ turtle) is a slow-growing reptile that is distributed widely across China. Prior to this study, the cDNA sequence of the growth hormone receptor (GHR) in the Reeve’s turtle, or how periods of starvation might influence the gene

Role of (p)ppGpp in Viability and Biofilm Formation of Actinobacillus pleuropneumoniae S8. [PDF]

open access: yes, 2015
Actinobacillus pleuropneumoniae is a Gram-negative bacterium and the cause of porcine pleuropneumonia. When the bacterium encounters nutritional starvation, the relA-dependent (p)ppGpp-mediated stringent response is activated.

Digestive studies with a feed developed for realimentation of starving reindeer

open access: yesRangifer, 1990
The properties of three different feeds were compared when offered to reindeer calves as single feeds after a starvation period of the 48 h. The feeds were lichen and two pelleted commercial reindeer feeds, RF-71 and RF-80.

Evolution of Thriftiness: An analytical viewpoint [PDF]

open access: yes, 2008
We examine here, using a simple mathematical model, the conditions under which thrifty genes or fetal programming could evolve. Obesity and related disorders are thought to have their roots in metabolic thirftiness that evolved to combat periodic ...

Molecular Basis of Bacterial Longevity

open access: yesmBio, 2017
It is well known that many bacteria can survive in a growth-arrested state for long periods of time, on the order of months or even years, without forming dormant structures like spores or cysts. How is such longevity possible?
