Anthropomorphic Test Device
A crash test dummy, or simply dummy, is a full-scale Anthropomorphism, anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision. Prior to the development of crash test dummies, automobile companies tested using human Cadaver, cadavers, animals and live volunteers. Cadavers have been used to modify different parts of a car, such as the seatbelt. This type of testing may provide more realistic test results than using a dummy, but it raises ethical dilemmas because human cadavers and animals are not able to consent to research studies. Animal testing is not prevalent today. Computational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
At (command)
at is a shell command for scheduling commands to be executed at a future time; once. The command was developed for Unix and is available on Unix and Unix-like systems, Windows, and ReactOS. Variants Unix-like On Unix-like operating systems, at reads a series of commands from standard input and collects them into one "at-job" which is carried out at a later date. The job inherits the current environment, so that it is executed in the same working directory and with the same environment variables set as when it was scheduled. It differs from cron, which is used for recurring executions (e.g. once an hour, every Tuesday, January 1 every year). As with cron, many Unix systems allow the administrator to restrict access to the at command. at can be made to mail a user when done carrying out a scheduled job, can use more than one job queue, and can read a list of jobs to carry out from a file instead of standard input. The Linux at command was mostly written by Thomas Koenig. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azimuth Tractor Drive
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system. Types of azimuth thrusters There are two major variants, based on the location of the motor: # Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears. # Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller without ge ...

1,4,6-Androstatrien-3,17-dione
1,4,6-Androstatriene-3,17-dione (ATD) is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue. It is used to control estrogen synthesis. ATD was present in some over-the-counter bodybuilding supplements until 2009, as well as Topical ATD solutions that work transdermally. The product was developed and commercialized in the dietary supplement market place by industry journeyman Bruce Kneller, who holds a United States Patent for use of the compound and related compounds (#7,939,517) and Gaspari Nutrition. ATD has many names in sports supplements including: 1,4,6 etiollochan-dione, 3, 17-keto-etiochol-triene, androst-1,4,6-triene-3,17-dione and many others. These all refer to CAS# 633-35-2. ATD may cause a positive test for the anabolic steroid Boldenone, of which it is a possible metabolite and production contaminant. ATD is also prohibited in amateur and professional spor ...

Acute Tryptophan Depletion
Acute tryptophan depletion (ATD) is a technique used extensively to study the effect of low serotonin in the brain. This experimental approach reduces the availability of tryptophan, an amino acid Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. Only these 22 a ... which serves as the precursor to serotonin. The lack of mood-lowering effects after ATD in healthy subjects seems to contradict a direct causal relationship between acutely decreased serotonin levels and depression. However, mood-lowering effects are observed in certain vulnerable individuals. For example, a meta-analysis show that the effect size for the effects of tryptophan depletion on mood in depressed people not taking antidepressants was large (Hedge's g = −1.9 (95% CIs −3.02 to −0.78) Hence, a more accurate interpretation ...

Antithyroid Agent
An antithyroid agent is a hormone inhibitor acting upon thyroid hormones. The main antithyroid drugs are carbimazole (in the UK), methimazole (in the US), and propylthiouracil (PTU). A less common antithyroid agent is potassium perchlorate. Classification based on mechanisms of action The mechanisms of action of antithyroid drugs are not completely understood. Based on their mechanisms of action, the drugs are classified into following six classes. Thyroid hormone synthesis inhbitors These drugs probably inhibit the enzyme thyroid peroxidase ( thyroperoxidase), decreasing iodide oxidation, iodination of tyrosyl residues in thyroglobulin, and coupling of iodotyrosyl and iodothyronyl residues. It is thought that they inhibit the thyroperoxidase-catalyzed oxidation reactions by acting as substrates for the postulated peroxidase-iodine complex, thus competitively inhibiting the interaction with the amino acid tyrosine. The most common drugs in this class are thioamides, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATD Fourth World

Against The Day
''Against the Day'' is an epic historical novel by Thomas Pynchon, published on November21, 2006. The narrative takes place between the 1893 Chicago World's Fair and the time immediately following World War I and features more than a hundred characters spread across the United States, Europe, Mexico, Central Asia, Africa and "one or two places not strictly speaking on the map at all," according to the book jacket blurb written by Pynchon. Like its predecessors, ''Against the Day'' is an example of historiographic metafiction or metahistorical romance. At 1,085 pages, it is the longest of Pynchon's novels to date. Title Besides appearing within the book itself, the novel's title apparently refers to a verse in the Bible (2 Peter 3:7) reading "the heavens and the earth ... rereserved unto fire against the day of judgment and perdition of ungodly men."LeClair, TomLead Zeppelin: Encounters with the unseen in Pynchon's new novelpos, a review of ''Against the Day'' in the Dec/Jan 2 ...
