Transmission Electron Microscopy
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temora Airport
Temora Airport is a small airport located northwest of Temora, New South Wales, Australia. Currently no regularly scheduled passenger fights serve the airport. The current owner, the Temora Shire Council, do not charge landing fees for aircraft to use the facility, encouraging a wide variety of general aviation uses, including skydiving, gliding, flight training, kit aircraft assembly and aircraft maintenance. It is also the home of the Temora Aviation Museum, and hosts regularly flying displays and events. History Due to the Temora area's favourable climate and geography, following the outbreak of World War II the airport was controlled by the Royal Australian Air Force and in 1941 No. 10 Elementary Flying Training School (10EFTS) was established to provide initial flight training for pilot graduates. During the unit's operation, the airfield was extended significantly, processing some 2527 graduates. At its peak in 1944, 97 de Havilland Tiger Moth aircraft were based at ...

Network Equipment Provider
Network equipment providers (NEPs) – sometimes called telecommunications equipment manufacturers (TEMs) – sell products and services to communication service providers such as fixed or mobile operators as well as to enterprise customers. NEP technology allows for calls on mobile phones, Internet surfing, joining a conference calls, or watching video on demand through IPTV (internet protocol TV). The history of the NEPs goes back to the mid-19th century when the first telegraph networks were set up. Some of these players still exist today. Telecommunications equipment manufacturers The terminology of the traditional telecommunications industry has rapidly evolved during the Information Age. The terms "Network" and "Telecoms" are often used interchangeably. The same is true for "provider" and "manufacturer". Historically, NEPs sell integrated hardware/software systems to carriers such as NTT-DoCoMo, ATT, Sprint, and so on. They purchase hardware from TEMs (telecom equipment ...

TEM Beta-lactamase
Beta-lactamases, (β-lactamases) are enzymes () produced by bacteria that provide multi-resistance to beta-lactam antibiotics such as penicillins, cephalosporins, cephamycins, monobactams and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase. Beta-lactamase provides antibiotic resistance by breaking the antibiotics' structure. These antibiotics all have a common element in their molecular structure: a four-atom ring known as a beta-lactam (β-lactam) ring. Through hydrolysis, the enzyme lactamase breaks the β-lactam ring open, deactivating the molecule's antibacterial properties. Beta-lactam antibiotics are typically used to target a broad spectrum of gram-positive and gram-negative bacteria. Beta-lactamases produced by gram-negative bacteria are usually secreted, especially when antibiotics are present in the environment. Structure The structure of a ''Streptomyces'' serine β-lactamase (SBLs) is given by . The alpha-beta fold ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecom Expense Management
Expense management refers to the systems deployed by a business to process, pay, and audit employee-initiated expenses. These costs include, but are not limited to, expenses incurred for travel and entertainment. Expense management includes the policies and procedures that govern such spending, as well as the technologies and services utilized to process and analyze the data associated with it. Software to manage the expense claim, authorization, audit and repayment processes can be obtained from organizations that provide a licensed software, implementation and support service, or alternatively, from software as a service (SaaS) providers. SaaS providers offer on-demand web-based applications managed by a third party to improve the productivity of expense management. Steps Expense management automation has two aspects: the process an employee follows in order to complete an expense claim (for example, logging a hotel receipt or submitting mobile phone records) and the activity ac ...

Threat And Error Management
In aviation safety, threat and error management (TEM) is an overarching safety management approach that assumes that pilots will naturally make mistakes and encounter risky situations during flight operations. Rather than try to avoid these threats and errors, its primary focus is on teaching pilots to manage these issues so they do not impair safety. Its goal is to maintain safety margins by training pilots and flight crews to detect and respond to events that are likely to cause damage (threats) as well as mistakes that are most likely to be made (errors) during flight operations. TEM allows crews to measure the complexities of a specific organization's context — meaning that the threats and errors encountered by pilots will vary depending upon the type of flight operation — and record human performance in that context. TEM also considers technical (e.g. mechanical) and environmental issues, and incorporates strategies from Crew Resource Management to teach pilots ...

Transient Electromagnetics
Transient electromagnetics, (also time-domain electromagnetics / TDEM), is a geophysical exploration technique in which electric and magnetic fields are induced by transient pulses of electric current and the subsequent decay response measured. TEM / TDEM methods are generally able to determine subsurface electrical properties, but are also sensitive to subsurface magnetic properties in applications like UXO detection and characterization. TEM/TDEM surveys are a very common surface EM technique for mineral exploration, groundwater exploration, and for environmental mapping, used throughout the world in both onshore and offshore applications. Physical principles Two fundamental electromagnetic principles are required to derive the physics behind TEM surveys: Faraday's law of induction and Lenz's Law. A loop of wire is generally energized by a direct current. At some time (''t0'') the current is cut off as quickly as possible. Faraday's law dictates that a nearly identical cur ...
