any 3d seismic survey can have an acquisition footprint. acquisition footprint is an expression of the surface geometry (most common on land data) that leaves an imprint on the stack of 3d seismic data. often we recognize it as amplitude and phase variations on time slices, which of course display the amplitudes within our data set at a specified two way time (cordsen, 2004). on the other hand,...

We describe a new approach for making real-time measurements of exocytosis and endocytosis in neurons and neuroendocrine cells. The method utilizes interference reflection microscopy (IRM) to image surface membrane in close contact with a glass coverslip (the "footprint"). At the synaptic terminal of retinal bipolar cells, the footprint expands during exocytosis and retracts during endocytosis,...

The footprint is thought to be an important fact in rotator cuff repairs and has been used to compare various cuff fixation techniques. The following experiment used two different measurement sensors to evaluate the footprint as it is affected by suture tensions in a transosseous equivalent suture bridge repair. It was found that suture tension has a direct effect on footprint contact are...

BACKGROUND With advances in arthroscopic surgery, many techniques have been developed to increase the tendon-bone contact area, reconstituting a more anatomic configuration of the rotator cuff footprint and providing a better environment for tendon healing. METHODS We present an arthroscopic rotator cuff repair technique which uses suture bridges to optimize rotator cuff tendon-footprint cont...

Hydropower accounts for about 16 % of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity – t...

BACKGROUND Traditional Bankart repair using bone tunnels has a reported failure rate between 0% and 5% in long-term studies. Arthroscopic Bankart repair using suture anchors has become more popular; however, reported failure rates have been cited between 4% and 18%. There have been no satisfactory explanations for the differences in these outcomes. HYPOTHESIS Bone tunnels will provide increas...

Article history: Received 22 May 2005 Received in revised form 19 September 2005 Accepted 26 September 2005 Available online 16 November 2005 Two prominent and alternate approaches, ecosystem service valuation and ecological footprints, link the production of ecosystem services with their consumption by societies. An overlapping goal of both approaches is to promote the sustainable use of ecosy...

extended abstract introduction the present paper examines the ecological footprint of kermanshah as the 9th largest city of iran. it also tries to answer the following question: dose the ecological environment of kermanshah support the basic needs of it's population? and are the biological systems of kermanshah able to answer all socio- economic questions related to different activities o...

Probe-based storage, also known as micro-electric mechanical systems (MEMS) storage, is a new technology that is emerging to bypass the fundamental limitations of disk drives. The design space of such devices is particularly interesting because we can architect these devices to different design points, each with different performance characteristics. This makes it more difficult to understand h...

1. introduction the concept of sustainable travel and transport is embedded in the broader concept of sustainable development, which relates to maintaining or improving the quality of human life and variety of social opportunities within the natural constraints and limits of the global ecosystem. the organization for economic cooperation and development (2004) defines an environmentally sustain...
