We present a 59-year-old patient with long standing chronic heart failure with a previous single chamber implantable defibrillator referred for upgrade to resynchronization therapy. Initial images of the CS revealed no lateral veins (Figure 1). The catheter was withdrawn to the ostium and contrast injection proximally revealed the presence of a separate CS (Figures 2 and 3). Manipulation of the...

BACKGROUND The anterior approach to the hip joint is widely used in pediatric and adult orthopaedic surgery, including hip arthroplasty. Atrophy of the tensor fasciae latae muscle has been observed in some cases, despite the use of this internervous approach. We evaluated the nerve supply to the tensor fasciae latae and its potential risk for injury during the anterior approach to the hip joint...

This paper presents a simple approach for load flow analysis of a radial distribution network. The proposed approach utilizes forward and backward sweep algorithm based on Kirchoff’s current law (KCL) and Kirchoff’s voltage law (KVL) for evaluating the node voltages iteratively. In this approach, computation of branch current depends only on the current injected at the neighbouring node and the...

and steady-state net photosynthetic rates of lateral branch shoots of Pseudotsuga menziesii var. glauca (Beissn.) Franco seedlings growing in the open and in the forest understory were investigated in situ. Mean incident photosynthetic photon flux density (PPFD) was 702.5 μmol m s on open-grown branches and 52.0 μmol m s on understory-grown branches. Mean daily durations of PPFD greater than 50...

background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...
