The quadrupole strength function of O is calculated making use of the SIII interaction, within the framework of continuum-RPA and taking into account collisions among the nucleons (doorway coupling). The centroid of the giant resonance is predicted at ≈ 14 MeV, that is much below the energy expected for both isoscalar and isovector quadrupole resonances in nuclei along the stability valley. Abo...

The advancement in technology has brought a new revolution in the military domain. The success of the two unmanned reconnaissance prototypes Predator and Hunter had paved the way to the development of more challenging remotely operated vehicles (ROVs), such as uninhabited combat aerial vehicles (UCAVs), used for locating, identifying, and destroying the enemy targets. As these semiautonomous sy...

The quadrupole strength function of 28O is calculated making use of the SIII interaction, within the framework of continuum-RPA and taking into account collisions among the nucleons (doorway coupling). The centroid of the giant resonance is predicted at ≈ 14 MeV, that is much below the energy expected for both isoscalar and isovector quadrupole resonances in nuclei along the stability valley. A...

We discuss the spin dependence of the effective two-body interactions appropriate for three-body computations. The only reasonable choice seems to be the fine and hyperfine interactions known for atomic electrons interacting with the nucleus. One exception is the nucleon-nucleon interaction imposing a different type of symmetry. We use the two-neutron halo nucleus Li as an illustration. We demo...

Probiotics provide us an alternative way to combat diseases and has been introduced for prevention and treatment of periodontal diseases. This review was initiated to explore whether the use of probiotics can influence the periodontal microbiota and periodontal health. The role of probiotics on periodontal disease was reviewed to analyse the clinical effects of oral probiotics on periodontal di...

BACKGROUND Traumatic brain injury (TBI) has been recognized as a major public health issue for several decades. Despite technological advancements in protective equipment and medical care available during recent military conflicts, TBI is the most common neurological condition among Soldiers and Marines evaluated for discharge from service. This study describes the demographic, service-related,...

Studies of the long-term cardiovascular consequences of combat stress are few and inconclusive. The association between remote exposure to combat and subclinical atherosclerosis was assessed among 5,347 men in the Atherosclerosis Risk in Communities study. Coronary artery plaque and carotid intima-media thickness (CIMT) were compared between non-veterans and veterans with and without one or mor...

Posttraumatic stress disorder (PTSD) is associated with an increased risk of ischemic heart disease, though the pathophysiologic mechanisms remain unclear. Carotid artery intima-media thickness (CIMT) is a measure of subclinical atherosclerosis. We examined whether PTSD and combat exposure were associated with CIMT in Vietnam War-era twins after controlling for shared genetic and childhood fact...

Nearly 25% of U.S. men aged 55 or older served in combat, yet its impact on aging is unknown. The relationship of posttraumatic stress disorder (PTSD) symptoms to combat exposure was examined in 1,210 veterans of World War II (WWII) and the Korean War, who were participants in the Normative Aging Study. Over 54% of WWII and 19% of Korean veterans reported combat experience. The relationship bet...

BACKGROUND Historic advances in combat prehospital care have been made in the last decade. Unlike other areas of critical care, most of these innovations are not the result of significant improvements in technology, but by conceptual changes in how care is delivered in a tactical setting. The new concept of Tactical Combat Casualty Care has revolutionized the management of combat casualties in ...
