A high concentration of CCN generally leads to the formation of clouds with a high concentration of small droplets; whereas fewer CCN lead to clouds with few large droplets.

«Periods of very intense North Atlantic circulation and higher Northern Hemisphere temperatures increased the preservation of microfossils in the sediment cores, whereas those with slower circulation, when the study site was primarily influenced from the south, were linked with decreased carbonate ion concentrations at our core site which led to partial dissolution,» said co-author Dr Luke Skinner, also from Cambridge's Department of Earth Sciences.

For example, research in Los Angeles is showing that small methane leaks in homes between the gas meter and heaters and stoves could be leading to higher atmospheric methane concentrations there, he said, whereas other cities may have old, leaking gas pipes.

Acute insulin stimulation significantly increased the fractional activity FV0.1 of GS in control cultures in the range of 0.1 pmol / l to 0.1 nmol / l (P < 0.05) and in diabetic cultures in the range of 0.1 pmol / l to 1.0 nmol / l (P < 0.05), whereas higher insulin concentrations diminished the effect of acute insulin stimulation in a dose - dependent pattern.

Acute insulin stimulation significantly decreases A0.5 for GS in cultures precultured at 0.1 pmol / l to 0.1 nmol / l and 10 — 100 nmol / l insulin, whereas higher chronic insulin concentrations diminished the effect of acute insulin stimulation (Fig. 4A).

Moreover, annexin V / propidium iodide staining showed that VPA only marginally decreased the viability of in vitro — differentiated Th1 and Th17 cells at a relatively high concentration (1 mM)(Supplemental Fig. 4A, 4B), whereas VPA readily inhibited the differentiation of Th1 and Th17 cells at a low concentration (0.2 — 0.5 mM), indicating that apoptosis induction was not the primary mechanism for Th1 and Th17 cell differentiation inhibition (28, 29).

with sperm concentration decreasing from spring towards summer, whereas the highest levels were observed at winter months.

The addition of sacha inchi oil slowed down glucose production in 16 (38.1 %) participants that showed a higher concentration of triglycerides before meals (fasting hypertriglyceridemia), whereas an improved expression of sirtuin - 1 (SIRT1), a gene responsible for regulating energy within the cells and coordinating cellular functions, was registered four hours after ingesting the meal enriched with sacha inchi oil, and linked to lowered levels of blood sugar measured at the same time.

In conclusion, our findings indicated that higher intakes of PHVOs were associated with elevated concentrations of inflammatory biomarkers, whereas higher intakes of non-HVOs were associated with lower plasma concentrations of these biomarkers.

Two longer - term studies, in persons without diabetes, that measured fasting blood β - hydroxybutyrate concentrations over 10 wk found that, whereas the concentrations increased over the first 2 — 4 wk, they then decreased and, after 10 — 12 wk, remained only slightly higher than those of dieters following other diets (21, 23).

This makes it much easier to meet and chat with singles who live nearby, whereas signing up for a site based in the US or Europe may have a higher concentration of American or European members.

For alkaline drugs, a high degree of ionic trapping leads to high antimicrobial concentrations in the tissue and secretions, whereas the acidic drugs such as the β - lactam antimicrobials do not reach concentrations equivalent to plasma concentrations.

What I think you mean is that if we get CO2 levels high enough to cause a serious problem, we can't just stop emitting and hope the concentration will drop in time to make a difference, whereas with methane, it decays fast enough that we need to worry more about the decay products than about methane itself.

This explains why the SO2 distribution largely follows the DMS plume contour, whereas MSA is present in more localized and concentrated areas associated with higher NOx concentrations.

Pixels with darker shading represent areas with a higher concentration of tree cover loss, whereas pixels with lighter shading indicate a lower concentration of tree cover loss.
