The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Lewis Acids and Bases

Lewis Acids and Bases

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Weak Base Solutions

Weak Base Solutions

Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Base Excision Repair

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Ions as Acids and Bases

Ions as Acids and Bases

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

DNA Base Pairing

DNA Base Pairing

Erwin Chargaff’s rules on DNA equivalence paved the way for the discovery of base pairing in DNA. Chargaff’s rules state that in a double-stranded DNA molecule,

Background:

Seismic soil liquefaction is a significant hazard during earthquakes.
Accurate assessment of liquefaction triggering is crucial for infrastructure safety.
Existing databases require compilation and quality control for robust analysis.

Purpose of the Study:

To compile and present a detailed database of seismic soil liquefaction triggering and non-triggering case histories.
To provide transparent access to case history data for research and development.
To support the creation of advanced SPT-based liquefaction triggering relationships.

Main Methods:

Compilation and screening of case histories for data completeness and quality.
Processing of case history data for the development of triggering relationships.
Inclusion of a spreadsheet summary and maximum likelihood assessment.

Main Results:

A database comprising 113 liquefaction, 95 non-liquefaction, and 2 marginal liquefaction case histories.
Data spans seismic events with moment magnitudes (Mw) from 5.9 to 8.3.
Transparent presentation of input parameters and processing details for 210 case histories.

Conclusions:

The presented database provides a valuable resource for geotechnical and earthquake engineers.
Enables researchers to access and compare case history processing protocols.
Facilitates the advancement of probabilistic and deterministic assessments of seismic soil liquefaction hazard.
