Consider the spontaneous emission term describing the contribution of the spontaneous emission to the laser oscillation, which appears as the final term on the right-hand side of the rate equation for the photon density (Eq. (6.21)). Since this term represents the component of the spontaneous emission belonging to the same mode as the laser oscillation (angular frequency !m), it is closely related to the gain for the oscillation mode. Consider a laser of index-guiding type, and let E ¼ E(r) ¼ E(x, y)E(z) be the complex electric field of the oscillation mode. ...
This book provides a review of image analysis techniques as they are applied
in the field of diagnostic and therapeutic nuclear medicine. Driven in part by
the remarkable sophistication of nuclear medicine instrumentation and increase
in computing power and its ready and inexpensive availability, this is
a relatively new yet rapidly expanding field. Likewise, although the use of
nuclear imaging for diagnosis and therapy has origins dating back almost to
the pioneering work of Dr G.

Engine management systems are designed to ensure that the vehicle complies with emissions regulations as well as to provide improved performance. This means that the number of sensors and actuators is considerably greater than for a simple fuelling or ignition system.
Automation is the use of control systems (such as numerical control, programmable
logic control, and other industrial control systems), in concert with other applications of
information technology (such as computer-aided technologies [CAD, CAM, CAx]), to control
industrial machinery and processes, reducing the need for human intervention. In the scope
of industrialization, automation is a step beyond mechanization.
Information security does not guarantee the safety of your organization or your information or your computer systems. Information security cannot, in and of itself, provide protection for your information. That being said, information security is also not a black art. There is no sorcery to implementing proper information security and the concepts that are included in information security are not rocket science. In many ways, information security is a mindset. It is a mindset of examining the threats and vulnerabilities of your organization and managing them appropriately.
SPECT viết tắt của cụm từ Single Photon Emission Computed Tomography; Là một thiết bị ứng dụng kỹ thuật y học hạt nhân để chẩn đoán hình ảnh chức năng của các cơ quan trong cơ thể. Hình ảnh mà SPECT thu được không phải là hình thể giải phẫu mà là hình ảnh phản ánh chức năng của cơ quan.
Clients in the system specify an interest in the type of events that they are interested in.
Some examples of interests speciﬁed by clients could be sports events or events sent to a
certain discussion group. It is the system, which computes the clients that should receive a
certain event. A particular event may thus be consumed by zero or more clients registered
with the system. Events have explicit or implicit information pertaining to the clients which
are interested in the event.
The extraordinary mechanical properties and unique electrical properties of carbon nanotubes (CNTs)
have stimulated extensive research activities across the world since their discovery by Sumio Iijima of the
NEC Corporation in the early 1990s. Although early research focused on growth and characterization,
these interesting properties have led to an increase in the number of investigations focused on application
development in the past 5 years.
How can you tell if a technology has reached critical mass?
Easy: you look at how much damage it’s causing. Pretty
much every human invention is neutral in itself; any benefits
(or drawbacks) come from the way it’s used: atomic
energy can be used to power a city or destroy it; cars make it travel
over distances that were unthinkable just a hundred years ago
possible, and are happily destroying our planet with their polluting
There have been several significant advances innuclearmedicine since the publication of the
second edition of Practical NuclearMedicine. The last seven years have seen great strides in
instrumentation, including new coincidence detectors, the development of a wider variety
of crystals, and the advent of combined anatomical/functional imaging devices, including
PET/CT and SPECT/CT. PET imaging with 18F-FDG has become a mainstay of many
clinical settings, and other radiotracers are finding theirway into the rapidly expanding field
of oncologic PET.
nformation Technology is responsible for approximately 2% of the world’s emission of greenhouse gases. The IT sector itself contributes to these greenhouse gas emissions, through its massive consumption of energy - and therefore continuously exacerbates the problem. At the same time, however, the IT industry can provide the
The KRONE F/FTP 450/23 cable is designed for applications up to 450 MHz and provides transmission
performance meeting Category 6 specifications. This cables are low skew products, i.e. the difference in
propagation delay between the individual pairs is very low.
This is increasingly being requested for Gigabit Ethernet. The suitability of the cable for high-bit-rate
transmission systems ensures a high degree of future proofing. Additional features are the slim design and
low weight of the cables. Each pair is individually shielded (FTP).
Many of these failures can be caused by manufacturing defects and / or
design procedure is inconsistent with a particular emphasis on areas disrupted
the vessels. Sound emission data were collected on the actual ship and trends in the data
were analyzed, resulting in a load standard and appraisal procedures (CARP, 1982).
The concept was later developed into the ASME boiler and pressure vessel
Code and is used today (ASME 2010a and 2010b). AE is still the preferred method

The number of diagnostic nuclear medicine procedures has grown in the fi rst few
years of the new century. Nuclear cardiology has diversifi ed, stimulating development
of new equipment and imaging protocols. Gated myocardial perfusion imaging
completed with quantifi cation is now a standard procedure. Faster computers have
led to improved reconstruction techniques, higher image quality, increased patient
throughput and more automated acquisition and processing protocols.
Noninvasive cardiac imaging is an integral part of the practice of current clinical cardiology.
During the past three decades a number of distinctly different noninvasive
imaging techniques of the heart, such as radionuclide imaging, echocardiography, magnetic
resonance imaging, and X-ray computed tomography have been developed.
Remarkable progress has been made by each of these technologies in terms of technical
advances, clinical procedures, and clinical applications/indications.
