BACKGROUND End-tidal P(CO(2)) (Pe'(CO(2))) is routinely used in the clinical assessment of the adequacy of ventilation because it provides an estimate of Pa(CO(2)). How well Pe'(CO(2)) reflects Pa(CO(2)) depends on the gradient between them, expressed as ΔPa-e'(CO(2)). The major determinant of ΔPa-e'(CO(2)) is alveolar dead space (Vd(alv)). The fraction of inspired O(2) (Fi(O(2))) is not though...
Leukocytoclastic vasculitis (LV) is characterized by neutrophilic invasion and fibrinoid necrosis along with endothelial enlargement in postcapillary venules. Annular appearance of LV (ALV) is rare, but it can be accompanied by several systemic diseases. One of these systemic diseases is ulcerative colitis (UC), a subgroup of inflammatory bowel disease. Only one case was previously reported in ...
Ž . An effective approach to obstacle detection and avoidance for autonomous land vehicle ALV navigation in outdoor road environments using computer vision and image sequence techniques is proposed. To judge whether an object newly appearing in the image of the current cycle taken by the ALV is an obstacle, the object shape boundary is first extracted from the image. After the translation from ...
The literature review is devoted to the peculiarities of artificial lung ventilation (ALV) in patients with morbid obesity during laparoscopic oncosurgical interventions Trendelenburg position. At present, there are no consensus recommendations on choice optimal ALV mode anesthesia this area oncosurgery. When analyzing data obtained from other types operations, was impression that were signific...
avian leukosis viruses (alvs) cause different types of tumours in poultry and can affect the health and egg production of the birds. to investigate the presence of the virus in chicken layer flocks in shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
Several models have been proposed for visual homing in insects. These work well in small-scale environments but performance usually degrades significantly when the scale of the environment is increased. We address this problem by extending one such algorithm, the average landmark vector (ALV) model, by using a novel approach to waypoint selection during the construction of multi-leg routes for ...
