Distal and non-distal Pairs
نویسندگان
چکیده
The aim of this note is to determine whether certain non-o-minimal expansions of o-minimal theories which are known to be NIP, are also distal. We observe that while tame pairs of o-minimal structures and the real field with a discrete multiplicative subgroup have distal theories, dense pairs of o-minimal structures and related examples do not.

Distal and Non-distal Behavior in Pairs
The aim of this work is an analysis of distal and non-distal behavior in dense pairs of o-minimal structures. A characterization of distal types is given through orthogonality to a generic type in Meq, non-distality is geometrically analyzed through Keisler measures, and a distal expansion for the case of pairs of ordered vector spaces is computed.
متن کاملAssessment of the treatment outcome of closed extra-articular distal tibia fracture: IM nailing vs plating
Abstract Background: The tibial diaphyseal fractures are the most common type of long bone fractures encountered by most orthopedic surgeons. In accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia fractures have the second incidence of all tibia fractures after the middle tibia fractures. The purpose of the study was to asses...
متن کاملFunctional Results of Unstable (Type 2) Distal Clavicle Fractures Treated with Superior Anterior Locking Plate
Background: The treatment of distal clavicle fracture is always a challenge, as it is mostly unstable and has higherrate of delayed union, malunion, non-union and associated acromioclavicular arthritis. So the management of thesefractures remains controversial. The purpose of this study is to evaluate the functional results of Type 2 distal endclavicle fractures treated with superior anterior l...
متن کاملDistal Renal Tubular Acidosis with Grade 4 Vesicoureteral Reflux in a Child with Single Kidney
Introduction Renal tubular acidosis (RTA) is a non-uremic defects of urinary acidification. It is characterized by a normal anion gap hyperchloremic metabolic acidosis; plasma potassium may be normal, low or high-depending on the type of RTA. These syndromes differ from uremic acidosis which is associated with a high anion gap, decreased glomerular filtration with enhanced proton secretion b...
متن کاملDistal Femoral Osteotomy in Genovalgum: Internal Fixation with Blade Plate Versus Casting
Background: To compare the results of two different ways of distal femoral osteotomy stabilization in patients suffering from genuvalgum: internal fixation with plate, and casting. Methods: In a non-randomized prospective study, after distal femoral osteotomy with the zigzag method, patients were divided into two groups: long leg casting, and internal fixation with blade plate. For all pati...
