high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

PURPOSE To describe the clinical characteristics, management and treatment outcomes of patients with post-surgical suprachoroidal hemorrhage (SCH). METHODS A retrospective cross-sectional study was conducted, in which the medical records of 9 consecutive patients with SCH admitted to the Goldschleger Eye Institute were reviewed. RESULTS The mean age was 74 years (range 61-84) and the mean f...

INTRODUCTION Neonatal mastitis is a rare infection. When it does occur, infants younger than 2 months of age are typically affected and the majority of cases are caused by Staphylococcus aureus. We present the first reported case of neonatal mastitis caused by Acinetobacter baumannii, an unusual organism for this type of infection. CASE PRESENTATION A 15-day-old full-term Caucasian male neona...

The title compound, C(34)H(30)N(4)O(2), lies on an inversion center and consists of two 3-substituted-1H-indole units linked by a 1,2-dimethyl-enehydrazine bridge. It is one of numerous examples in which two aromatic ring systems are joined by this 4-atom bridge. The geometry of the centrosymmetric bridge is: C(arom)-C = 1.444 (3), C=N = 1.284 (3), N-N = 1.414 (4) Å, C(arom)-C=N = 122.6 (2) and...

!ikansparency is a popular feature in a distributed system where users can access any local or remote resources just as if they were local. As different units in the distributed environment can be integrated into a single unit by means of a distributed operating system, so can multiple LANs be connected by transparent bridges and appear as one LAN to upper layer protocols and end stations. End ...

BACKGROUND Low haematocrit (Hct) is associated with a higher rate of post-operative complications, increased mortality, and additional medical costs following cardiac surgery. Predictors of post-operative Hct in lumbar fusion are unclear and may be beneficial in avoiding adverse surgical outcomes. METHODS A total of 704 lumbar disc herniation patients (385 males, 319 females) who underwent pr...

Chest tubes and their accompanying pleural drainage units continue to present challenging questions regarding their optimal use. Appropriate chest tube size selection to accommodate the clinical situation is key, especially in the setting of large pleural air leaks lest a tension pneumothorax ensue. Connection of an appropriate pleural drainage unit to the chest tube is equally important to obv...

The Rivoli-Avigliana end moraine system (Italian Western Alps) hosts an important stratigraphic archive of Pleistocene glaciations. A new geological map provides a 3D architecture the that reveals complex glacial, alluvial and lacustrine units. Six glacial units were recognized. During deposition four older (Early-Middle Pleistocene) morphology valley outlet had different drainage pattern from ...

performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...

past earthquakes have demonstrated that old rc bridges may be seismically vulnerable. bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. in this research an existing concrete bridge representative of the most common bridges in the highway system in iran are studied. push over and nonlinear ...
