We analyze the famous Wolf’s sunspot numbers. We discovered that the distribution of the sunspot number fluctuations is a mixture of the BHP distribution with the Gaussian distribution.

The production of steel normally constitutes the inception of most Supply Chains in different areas. Steel manufacturing companies are strongly affected by bull whip effects. Due to nondeterministic incoming orders and changes of customer requirements on accepted orders, making the right decision at a certain stage can be the difference between earning or loosing a great turnover. Improving the...

Modern steel making processes are based on electrical arc furnaces (EAF) or converters, secondary metallurgy and CSC equipment. Steel casting processes are carried on as the continuous ones, which today are the dominating methods in global quantities of steel production. These methods make possible production of the continuous castings of predetermined profiles and dimensions, and therefore to ...

BACKGROUND Past time-series studies of the health effects of fine particulate matter [aerodynamic diameter ≤ 2.5 µm (PM2.5)] have used chemically nonspecific PM2.5 mass. However, PM2.5 is known to vary in chemical composition with source, and health impacts may vary accordingly. OBJECTIVE We tested the association between source-specific daily PM2.5 mass and hospital admissions in a time-seri...

We present surface estimates of bacterial respiration, bacterial heterotrophic production (BHP), and bacterial growth efficiency (BGE), and their relationship with nutrient availability, along a trophic gradient from coastal upwelling waters to the open-ocean waters of the eastern North Atlantic. Bacterial respiration generally ranged between 10 and 30 mg C L21 d21 and was relatively unaffected...

An essential dietary flavonoid known as curcumin has positive health effects and inhibits the synthesis of reactive oxygen species (ROS). The aim this study is to look at signs oxidative stress in red blood cells (RBCs) treated with a function age. A total 116 healthy volunteers ranging age from 20 81 years provided clinically pertinent samples for investigation. Three groups subjects were crea...
