The earthquake motion is assigned
classified by Japan's land area is classified into three categories according to level
seismic risk and adjust the seismic motion by using the regional adjustment factor of 1.0, 0.85
and 0.7 depending on the classification of the area.
Meanwhile, the studies to calculate seismic waveforms unique to the target area of seismic
design has been conducted in recent years.
ADC’s OmniReach™ FTTX Solutions are the

This introduction to Evidence-Based Dentistry provides a much-needed orientation in the subject for students and professionals alike. It is a ground-level book for those seeking to understand evidence-based dentistry and its significance for clinical practice. The book is anchored in the dental literature: the majority of the chapters offer guidance on interpreting a full published paper; where both the subject of the paper and the study design is of relevance to the field of dentistry.
The AFD above ground fiber distribution system provides access, storage and cable
management for passive outside plant fiber optic installations. The AFD houses custom
termination, termination/splice and slack storage panels for use as an above ground
fiber cross-connect system.
The AFD is a heavy-duty, weather-resistant cabinet providing superior cable management
and protection of fibers. The AFD is a single-sided cabinet designed to provide
front access for both splicing and terminating fibers....
Traditionally astrophysics has concerned itself with minimum time-scales measured
in hours rather than seconds. This was understandable as the available recording
media were slow; e.g. chart recorders and photographic plates. In the 1950s, 60s
and 70s wavebands away from the optical were developed; from ground based
radio studies to space and balloon borne high energy work. In contrast to optical
wavelengths instrumentation in these (high and low energy) regimes was capable
of time resolutions of less than a second....
As fiber-to-the-x (FTTX) architectures gain momentum as a means for delivering
high-speed broadband services to homes and small businesses, many questions
have surfaced regarding the best way to connect the large number of drop
cables feeding into the network. Drop cables typically connect each optical
network terminal (ONT) at the subscriber premise to a fiber access terminal
where they are then connected to a main fiber distribution cable.
In our quest to elucidate the origin of the universe and the formation of
galaxies, particularly that of the Milky Way in which we live, astounding
progress has been made in recent years through observational and theoretical
studies. Not only have gigantic surveys covering a large fraction of the sky
brought statistics enlightening evolutionary paths of galaxies, but powerful
instruments, such as radio interferometers and ground- and space-based optical/
infrared telescopes, have been able to map individual objects with high
sensitivity and spatial resolution.

One night in 1996, an unusually hard rain sent a wall
of water onto the campus of Colorado State University
(CSU) in Fort Collins, Colo. The flood gutted
the ground floor and basement levels of 14 buildings, submerging
main distribution frames in each building. Panels
were ripped from walls, rooms filled with mud, patch cords
floated away, and fiber optic cable filled with water. No one
on campus was hurt but, needless to say, the network was
