hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

objective: introduction of fiber-reinforced composites (frc) greatly enhanced the restoration of fractured anterior teeth. the purpose of this study was to assess the effect of fiber reinforcement on fracture resistance of incisal edge composite restorations of variable thicknesses. methods: forty extracted sound human maxillary incisors were divided into four groups of 10. incisal reduction wa...

Abstract Decadal changes in land use/land cover for Balachaur watershed in Nawanshahar district, Punjab, India were studied using black and white aerial photographs for March 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (FCC) of IRS-1D LISS-III on 1:50,000 scale for March 2002, September 2002, and May 2003 and interpreted visually to prepare land use/land...

The onshore oil and natural gas industries of China have started a large-scale development when crude oil reserves have been difficult to recover. The stratum fracture modification is an indispensable measure to efficiently develop oil and gas fields. Hydraulic fracturing is the most important reservoir stimulation technique, but it is still faced with various problems such as the failure to fr...

Random graph theory is used to examine the “smallworld phenomenon” – any two strangers are connected through a short chain of mutual acquaintances. We will show that for certain families of random graphs with given expected degrees, the average distance is almost surely of order log n/ log d̃ where d̃ is the weighted average of the sum of squares of the expected degrees. Of particular interest ar...

In many communities there is an elite, a relatively small group of participants that is well connected and highly influential. In order to understand the whole community and the underlying mechanisms it is hence very helpful to study the characteristics and the emergence of the elite. In the past it has been shown that various social networks exhibit surprisingly similar properties, like power ...

INTRODUCTION Structurally intact, cancellous bone is an attractive grafting material because it can allow a greater degree of ingrowth by host tissues than cortical bone and may also be used as structural support for other biomaterials used to deliver osteogenic agents. Gamma radiation sterilization is a commonly used technique for reducing the risk of disease transmission with allograft, but i...
