Next Generation Air Traac Management will allow for the possibility of free ight, in which each aircraft chooses its own optimal route, altitude and speed. In a free ight environment, the trajectories of several aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. This paper presents a method for noncooperative connict resolution in which each ai...

Ultrasound lung comets (ULCs) are a nonionizing bedside approach to assess extravascular lung water. We evaluated a protocol for grading ULC score to estimate pulmonary congestion in heart failure patients and investigated clinical and echocardiographic correlates of the ULC score. Ninety-three patients with congestive heart failure, admitted to the emergency department, underwent pulmonary ult...

Klassen, Christopher L., Jay H. Traverse, and Robert J. Bache. Nitroglycerin dilates coronary collateral vessels during exercise after blockade of endogenous NO production. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H918–H923, 1999.—In a previous study nitroglycerin failed to dilate coronary collateral vessels during exercise. This study tested the hypothesis that failure of nitroglycerin t...

The symptomatology of auras and seizures is a reflection of activation of specific parts of the brain by the ictal discharge, the location and extent of which represent the symptomatogenic zone. The symptomatogenic zone is presumably, though not necessarily, in close proximity to the epileptogenic zone, the area responsible for seizure generation, the complete removal or disconnection of which ...

After myocardial infarction (MI), the border zone expands chronically, causing ventricular dilatation and congestive heart failure (CHF). In an ovine model (n = 4) of anteroapical MI that results in CHF, contrast echocardiography was used to image short-axis left ventricular (LV) cross sections and identify border zone myocardium before and after coronary artery ligation. In the border zone at ...

Aims Prediction of trabecular fracture zone is a wide challenge not yet solved. Some in-vitro studies pointed out the importance of local variation of the framework for the global behavior of the whole trabecular structure [1-4]. Researchers agree that the identification of the weakest link in the trabecular framework can lead to the prediction of the fracture zone, first, and of the failure ev...

Coal mine underground reservoir water storage technology is an effective technical way to achieve high efficiency of coal mining and protection resources. The stability pillar dam plays a decisive role in the safe stable operation reservoirs. Mining adjacent working faces long-term erosion are main influencing factors dam. In this paper, fluid-solid coupling calculation model for deformation ev...

The article demonstrates the factors of importance in the early and late failures of dental implants based on literature review. An implant location is one of many factors that can influence a success or failure of dental implants. The author identifies and describe four alveolar jaw regions--functional implant zones--with unique characteristics of anatomy, blood supply, pattern of bone resorpt...

Objective Although proximal neck dilatation following infrarenal endovascular aneurysm repair (EVAR) is common and associated with graft failure, little known about sealing zone its clinical relevance fenestrated EVAR (FEVAR). We studied seal (PSD) dynamics FEVAR assessed significance.

BACKGROUND Although numerous studies have assessed arthroscopic medial meniscal repairs, few studies have focused on factors affecting outcomes of vertical longitudinal and bucket-handle repairs. PURPOSE To evaluate the factors affecting clinical outcomes of arthroscopically repaired traumatic vertical longitudinal and bucket-handle medial meniscal tears. STUDY DESIGN Case series; Level of ...
