Reliability and Validity01:29

Reliability and Validity

13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Distribution Reliability and Automation

518
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Lewis Acids and Bases02:33

Lewis Acids and Bases

48.4K
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

25.3K
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 Repair01:54

Base Excision Repair

26.4K
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

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:

Area of Science:

  • Veterinary Microbiology
  • Food Safety
  • Poultry Science

Background:

  • Chicken-associated Campylobacter spp. are a leading cause of food poisoning in Europe.
  • Studying host-pathogen interactions requires reliable chicken colonization methods.
  • Current methods like gavage are invasive and less representative of field contamination.

Purpose of the Study:

  • To develop a less invasive and more reproducible method for colonizing broiler chickens with Campylobacter spp.
  • To evaluate the survival of Campylobacter spp. in seeded litter over 24 hours.
  • To assess the efficacy of the litter seeding method for Campylobacter colonization in chickens.

Main Methods:

  • Campylobacter spp. survival in seeded litter was tested over 24 hours.
  • Three groups of broiler chickens were exposed to different Campylobacter mixes via litter seeding.
  • Livers and ceca were collected from euthanized chickens for Campylobacter spp. assessment.

Main Results:

  • Campylobacter spp. survived at detectable levels in litter for at least 3 hours post-seeding.
  • All liver and 28/30 cecal samples tested positive for Campylobacter spp. colonization.
  • The litter seeding method successfully colonized chickens, with variations in bacterial counts between different Campylobacter mixes.

Conclusions:

  • A reliable and less invasive method for colonizing broiler chickens with Campylobacter spp. using seeded litter was developed.
  • This novel method negates the need for gavage and better represents natural contamination pathways.
  • The findings support the use of this method for future research on Campylobacter host-pathogen interactions in poultry.
