During milking the teat cup liner is the interface between the teat of a dairy cow and the milking system, so it should be very well adapted to the teat. Therefore, the aim of the present study was to determine the effect of liner type on the directly measuring teat load caused by a collapsing liner with a pressure-indicating film. The Extreme Low pressure-indicating film was used to detect the...

femoral head and subsequent degenerative arthritis of the hip. Pain and ambulatory limitations prompt orthopedic surgeons to consider total hip arthroplasty (THA). In these patients, THA can be challenging secondary to distorted anatomy, prior surgeries, and significant soft-tissue contractures. The case reported here illustrates early prosthetic dislocation after THA in a young patient with si...

BACKGROUND Total knee arthroplasty (TKA) is a successful therapy for functional improvement and pain relief in advanced symptomatic degeneration of the knee joint. But it can be associated with many complications, one of which is instability. CASE PRESENTATION A 70-year-old woman was referred to our hospital because of right knee dislocation after TKA was performed on her right knee due to se...

This paper introduces the concept, theory of operation and applications soft open points for direct current networks (DCSOPs). The DCSOP is based on a bidirectional DC–DC converter actively controlled to behave like normal conductor. Unlike conductor, can transfer electric power between nodes at different voltage levels. With this advantage, effectively control flow direction. Thus, DCSOPs play...

Flying insects are remarkably agile and robust. As they fly through cluttered natural environments, can demonstrate aggressive acrobatic maneuvers such as backflip, rapid escape, in-flight collision recovery. Current state-of-the-art subgram microaerial-vehicles (MAVs) predominately powered by rigid actuators piezoelectric ceramics, but have low fracture strength (120 MPa) failure strain (0.3%)...

The aim of this study was to compare the 10-year survival rate, pelvic osteolysis frequency and linear head penetration rate of the Hexloc and Ringloc liners used together with a partially threaded porous and hydroxyapatite coated cup and the Bi-Metric uncemented femoral stem. The 15-year results for the cup with the Hexloc liner are also reported. We included 332 consecutive hips (166 Hexloc a...

We report a complication during total hip arthroplasty using an uncemented press-fit acetabular shell and ceramic liner for a woman with osteoarthritis. Fracture of the ceramic liner occurred during its insertion owing to non-concentric reduction. The main body of the ceramic liner became wedged in the acetabular shell and was resistant to removal. The shell itself was immovable owing to the pr...

Objective: This case report aims to introduce the black triangle therapy in Miller’s Class IV gingival recession. Methods: The patient complained of spacing between upper and lower teeth causing food accumulation, “long teeth”, receding gums which were unaesthetic during speaking. Clinical examination maxillary mandibular anterior revealed Miller recession, large triangles, no tooth mobility no...
