Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Network Covalent Solids02:18

Network Covalent Solids

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Regulation of Food Intake01:30

Regulation of Food Intake

2.4K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Scaling01:26

Scaling

583
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Area of Science:

  • Public Health
  • Urban Planning
  • Nutritional Science

Background:

  • Fast-food consumption significantly impacts British children's nutrition.
  • Zoning policies are being implemented in British cities to limit children's access to fast food near schools.

Purpose of the Study:

  • To conduct the first nation-wide analysis of fast-food outlet proximity to schools in Britain.
  • To precisely compute distances using the road network for effective zoning policy design.
  • To estimate the potential impact of zoning policies on the fast-food landscape and childhood nutrition.

Main Methods:

  • Linked large datasets including all roads, fast-food outlets, and schools across Britain.
  • Performed network analysis on a high-performance computing cluster.
  • Compared road network distances with Euclidean distances for accuracy.

Main Results:

  • Found strong spatial clustering of fast-food outlets, with 80% within 120m of another.
  • Using road network distance, one-third of fast-food outlets are within 240m of a school, compared to half using Euclidean distance.
  • Results were consistent across different levels of deprivation, supporting equitable policy development.

Conclusions:

  • Road network analysis provides a more accurate assessment of fast-food outlet proximity than Euclidean distance for policy-making.
  • Findings support the development of national zoning policies to improve child nutrition and combat obesity.
  • No correlation was found between outlet centrality and proximity, suggesting centrality is not a reliable policy target.
