Radioactivity level and the measurement of soil gas radon concentration in Dikili geothermal area, Turkey

Background: The natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in Dikili geothermal region, Turkey. Materials and Methods: The natural radionuclide content of soil samples were measured by NaI(Tl) gamma spectrometer system and the soil radon concentration were determined using Kodak-Pethe LR-115 Type II Solid State Nuclear...

Morphogen Gradients: Limits to Signaling or Limits to Measurement?

In Drosophila embryos, a concentration gradient of nuclear Dorsal protein controls pattern formation along the dorsal-ventral axis. Recent quantitative studies agree on the temporal dynamics of the gradient, but disagree on its spatial limits.

Fundamental Limits to Collective Concentration Sensing in Cell Populations.

The precision of concentration sensing is improved when cells communicate. Here we derive the physical limits to concentration sensing for cells that communicate over short distances by directly exchanging small molecules (juxtacrine signaling), or over longer distances by secreting and sensing a diffusive messenger molecule (autocrine signaling). In the latter case, we find that the optimal ce...

Measurement of Fluoride Concentration in Semnan Drinking Water Distribution

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...

Alberta Soil Phosphorus Limits Project

Agricultural systems often require added phosphorus to achieve optimum crop and livestock production. The application of soil amendments, such as inorganic fertilizers, manure, biosolids, and waste water, can improve soil fertility and help produce optimum crop yields. However, many of these amendments, particularly organic materials such as animal manure, are often applied in excess of crop nu...
