In accordance with the Federal Resource Allocation Criteria (RAC) policy (PDF, 144 KB, 4 pages), which defines objective criteria and a coordinated approach for prioritizing federal resource allocation to fusion centers, the federal government recognizes these designations and has a shared responsibility with state and local governments to support the national network of fusion centers.
"A fusion center is a collaborative effort of two or more agencies that provide resources, expertise and information to the center with the goal of maximizing their ability to detect, prevent, investigate, and respond to criminal and terrorist activity."
State and major urban area fusion centers (fusion centers) serve as primary focal points within the state and local environment for the receipt, analysis, gathering, and sharing of threat-related information among federal, state, local, tribal, and territorial (SLTT) partners. Located in states and major urban areas throughout the country, fusion centers are uniquely situated to empower front-line law enforcement, public safety, fire service (PDF - 22 pages, 2.21 MB), emergency response, public health, critical infrastructure protection (PDF - 30 pages, 3.54 MB) and private sector security personnel to lawfully gather and share threat-related information. They provide interdisciplinary expertise and situational awareness to inform decision-making at all levels of government. Fusion centers conduct analysis and facilitate information sharing, assisting law enforcement and homeland security partners in preventing, protecting against, and responding to crime and terrorism. Fusion centers are owned and operated by state and local entities with support from federal partners in the form of:
Our nation faces an evolving threat environment, in which threats not only emanate from outside our borders, but also from within our communities. This new environment demonstrates the increasingly critical role fusion centers play to support the sharing of threat-related information between the federal government and SLTT partners.
In 2007, the National Strategy for Information Sharing called for the establishment of "baseline operational standards" for fusion centers. In 2008, the federal government, in collaboration with SLTT partners, published the Baseline Capabilities for State and Major Urban Area Fusion Centers (PDF, 37 pages - 4.6 MB) to establish baseline operational standards and to outline the capabilities necessary for fully operational fusion centers. By achieving the baseline capabilities, a fusion center will have the necessary structures, processes, and tools in place to support the fusion process.
Additionally, both Fusion Center Directors and the federal government identified the protection of privacy, civil rights, and civil liberties (P/CRCL) as a key priority and an important enabling capability to ensure fusion centers protect the privacy and other legal rights of Americans, while supporting homeland security efforts.
Strengthening the ability of fusion centers to execute the COCs and ensure P/CRCL protections is critical to building an integrated National Network of Fusion Centers capable of sharing information with the federal government and SLTT partners during situations involving time-sensitive and emerging threats. In September 2010, federal, state, and local officials conducted a Baseline Capabilities Assessment (BCA), the first formal assessment of fusion center capabilities. The data collected during the BCA provided a snapshot of fusion center capabilities and identified major trends, as well as strengths and gaps across the National Network.
The current focus of the federal government is to support fusion centers in mitigating the capability gaps identified by the BCA and to assist fusion centers in reaching an enhanced level of capability for all four COCs and P/CRCL protections. The Department of Homeland Security, in coordination with federal interagency partners, has developed and provided a wide range of resources and services, including a guidebook, sample policies, templates, best practices, workshops, and various training sessions, to support fusion centers in strengthening their COCs and P/CRCL protections. The Department will continue to assist fusion centers in fully achieving and maintaining the COCs and P/CRCL protections.
In recent years, partners at all levels of government have reiterated the need for unified and coordinated support for fusion centers. The federal government is committed to assisting them in becoming centers of analytic excellence that serve as focal points for the receipt, analysis, gathering, and sharing of threat-related information among federal and SLTT partners. Federal interagency partners, including Department of Homeland Security, Department of Justice, Federal Bureau of Investigation, Office of the Director of National Intelligence, Program Manager for the ISE, Office of National Drug Control Policy, and Department of Defense, are committed to providing effective, efficient, and coordinated federal support to fusion centers. In turn, fusion centers support their SLTT partners by developing actionable intelligence, disseminating relevant information to homeland security partners, participating in the Nationwide SAR Initiative, and supporting the maturation of their statewide fusion processes.
Thank you for the detailed response. I appreciate your guidance and the advice of others. As for all of the duplicate and over dimensioning of the part. I added all of those dimensions in an attempt to fully constrain the sketch. I understand they can also cause confusion and also make the sketch more difficult to read.
During spinal fusion, a surgeon places bone or a bonelike material in the space between two spinal bones. Metal plates, screws or rods might hold the bones together. They then can fuse and heal as one bone.
Sometimes, surgery on the spinal bones of the neck occurs from the front. In the example shown, a damaged disk is removed, a bone graft is inserted, and plates and screws hold the bones together. This procedure is called anterior diskectomy and fusion.
A surgeon can get to the spine from the front, known as an anterior spinal fusion. From the back, it's known as posterior spinal fusion. Either way, a metal plate or rods and screws will hold the bones together until the bones heal.
Surgeons perform spinal fusion while the person having the procedure is unconscious, known as general anesthesia. There are several ways to do spinal fusion surgery. The technique the surgeon uses depends on where the bones to be fused are on the spine, the reason for the spinal fusion, and possibly, general health and body shape.
A hospital stay of two to three days is usually required following spinal fusion. Depending on the location and extent of your surgery, you may experience some pain and discomfort but the pain can usually be controlled well with medications.
Spinal fusion typically works for fixing broken bones, reshaping the spine or making the spine more stable. But study results are mixed when the cause of the back or neck pain is unclear. Spinal fusion often works no better than nonsurgical treatments for back pain with a cause that's not clear.
To fuse on our sun, nuclei need to collide with each other at very high temperatures, exceeding ten million degrees Celsius, to enable them to overcome their mutual electrical repulsion. Once the nuclei overcome this repulsion and come within a very close range of each other, the attractive nuclear force between them will outweigh the electrical repulsion and allow them to fuse. For this to happen, the nuclei must be confined within a small space to increase the chances of collision. In the sun, the extreme pressure produced by its immense gravity create the conditions for fusion to happen.
While conditions that are very close to those required in a fusion reactor are now routinely achieved in experiments, improved confinement properties and stability of the plasma are needed. Scientists and engineers from all over the world continue to test new materials and design new technologies to achieve fusion energy.
Nuclear fusion and plasma physics research are carried out in more than 50 countries, and fusion reactions have been successfully achieved in many experiments, albeit without demonstrating a net fusion power gain. How long it will take to recreate the process of the stars will depend on mobilizing resources through global partnerships and collaboration.
Ever since nuclear fusion was understood in the 1930s, scientists have been on a quest to recreate and harness it. Initially, these attempts were kept secret. However, it soon became clear that this complex and costly research could only be achieved through collaboration. At the second United Nations International Conference on the Peaceful Uses of Atomic Energy, held in 1958 in Geneva, Switzerland, scientists unveiled nuclear fusion research to the world.
The IAEA has been at the core of international fusion research. The IAEA launched the Nuclear Fusion journal in 1960 to exchange information about advances in nuclear fusion, and it is now considered the leading periodical in the field. The first international IAEA Fusion Energy Conference was held in 1961 and, since 1974, the IAEA convenes a conference every two years to foster discussion on developments and achievements in the field.
Importantly, nuclear fusion does not emit carbon dioxide or other greenhouse gases into the atmosphere, and so along with nuclear fission could play a future climate change mitigating role as a low carbon energy source.
More than two years since MIT claimed its scientists achieved a breakthrough in fusion energy, the university is claiming that new research "confirms" that the magnet-based design used in those tests isn't just impressive in a lab setting, but is practical and economically viable, too.
"Overnight, it basically changed the cost per watt of a fusion reactor by a factor of almost 40 in one day," Dennis Whyte, former director of MIT's Plasma Science and Fusion Center and a professor of engineering, said in a release. "Now fusion has a chance."
