Triaxial tests measure soil’s shear resistance, important for project planning. Soil samples are placed in a tube with a membrane, dropped into liquid, and squeezed. Test equipment measures pressure on the ground to determine cutoff point. Laboratories follow strict protocols, but results may vary. A triaxial test measures the soil’s ability to resist shear forces. […]
Combustion tests assess the safety and efficiency of fuel-operated appliances, including vent systems and fuel lines. Technicians visually inspect equipment and ventilation systems, check air quality, and perform burn tests to evaluate fuel efficiency and air flow. High levels of CO or CO2 can occur in airtight buildings, and net chimney temperature is also evaluated. […]
Placement tests assess a student’s skills and knowledge in various subjects and are required for college admission. Advanced Placement (AP) tests can provide college credit and higher-level course placement. Computerized placement tests (CPT) are available and provide information on reading, sentence skills, math, and science. The Accuplacer is a popular college placement test worldwide. A […]
Arterial blood gas (ABG) tests measure blood oxygen uptake, lung and kidney function, and pH levels. ABG tests carry some risk of complications and should be discussed with a healthcare professional. Elevated carbon dioxide levels may indicate respiratory failure, while low levels can indicate respiratory alkalosis. ABG tests can also detect metabolic and respiratory conditions, […]
A creatinine blood test checks the level of creatinine in the kidneys to ensure they are functioning normally or to check for diseases. It requires a blood sample and fasting for at least eight hours. Doctors may also order a BUN test. Annual checkups are recommended for kidney health. A creatinine blood test is a […]
Forensic specialists use microscopic particles left at a crime scene to identify suspects or victims. Hair, fibers, paint, dirt, and biological fluids are analyzed to narrow down unknowns and support other findings. The Locard’s Exchange Principle states that there is an exchange of evidence during a crime. Tracing evidence usually consists of particles, mostly microscopic, […]
The cold pressure test involves immersing a patient’s hand in ice-cold water to stimulate the sympathetic nervous system and assess pain tolerance. Abnormal responses may indicate a neurological problem, and further tests may be needed for diagnosis and treatment. The cold pressure test involves immersing the patient’s hand in cold water to stimulate the sympathetic […]
Cold testing involves using colder-than-average temperatures to test different objects and materials. It can be used to determine the hardiness of seeds, the likelihood of oil becoming cloudy, and the strength of metal objects in cold weather. The degree of cold used depends on the object being tested and the desired results. A cold test […]
The test notebook is a popular way to organize trial documents, with each section of the trial having a separate tabbed divider in a three-ring binder. The notebook includes sections for facts, pleadings, motions, discovery, jury selection, direct and cross-examination, opening and closing statements, and search and jury instructions. The notebook’s main advantage is organization […]
Tensile testing measures a material’s strength by applying force until it changes shape or breaks. It provides information on elongation, yield point, and ultimate strength. Tensile strength is measured in Pascals or kilo pounds per square inch. Modern machines are highly accurate and universal testing machines can perform multiple stress tests. Tensile testing is important […]
Banks undergo reviews and examinations by external regulators or entities, focusing on capital adequacy, asset quality, management, earnings, liquidity, and risk sensitivity. The exam may result in closer scrutiny or recommendations to improve the bank’s operations and management. A bank exam includes a series of tests and reviews that ensure that a bank is sound […]
The Stanford-Binet intelligence scales assess five cognitive areas using 10 verbal and nonverbal subtests. Developed by Alfred Binet in France, it was later revised by Lewis Terman. Scoring involves summing scores for each subtest and converting into a scaled score, with a range of total IQ between 40 and 160. The test is appropriate for […]
The Hirschberg test is a noninvasive screening for strabismus that can be performed on patients of any age during a routine eye exam. If signs of strabismus are identified, additional tests may be recommended to develop treatment recommendations. The test involves shining a light into the eye and measuring the degree of deviation to determine […]
A tension test measures the force a material can tolerate before breaking. The test is conducted using a mechanical instrument and graphs are used to identify the material’s strength. Principles like Hooke’s Law and yield strength help interpret results. The test is conducted on samples of the material and is used to choose materials for […]
The witness stand is where witnesses testify in court. Evidence presented varies by case type. Witness testimony can be used in civil and criminal cases, and witnesses give a deposition before taking the stand. Witnesses are placed on a list, and attorneys question them while they sit on the stand. A witness stand is the […]
A trial brief is a formal document prepared by the legal team to provide information about a person’s position in a case and support it with legal scholarship. Judges review these briefs to understand legal issues and make fair decisions. The language used is formal and carefully chosen. A record is a formal statement made […]
A hemoglobin test is a blood test used to check the levels of hemoglobin in the body, which can indicate various health problems. Hemoglobin transports oxygen in the blood, and normal levels range from 12-18 grams per deciliter in adults. Low levels can indicate anemia, while high levels can indicate dehydration or heart disease. The […]
Density testing determines the density of soil, rock, or other materials for construction safety. Various methods are used in the field or laboratory. Testing is required before construction and periodic testing can identify issues. Failure to address poor soil can lead to structural failure. Regulators may require density test results. A density test is a […]
The nystagmus test measures involuntary eye movements and is commonly used in investigations for driving under the influence. A police officer may conduct the test during a field sobriety test, along with other standardized tests. If the driver fails the test, they may be arrested. The term “nystagmus” refers to the involuntary movement of the […]
Accelerated stability tests estimate the shelf life of perishable products under normal conditions by subjecting them to stress conditions. This eliminates the need for long-term storage and allows for appropriate expiration dates. Controlled conditions are critical, but physical and chemical changes may occur that would not under normal conditions. Regulatory agencies have guidelines for expedited […]
