background: ninety percent of all people sometimes during their lives experience low back pain, and 30-40% develops radicular leg pain with the sciatica characteristics. although for clinical diagnosis of lumbar disc herniation (ldh) straight leg raising (slr) test in 85-90% of cases indicates ldh, but in our practice with ldh patients this test is frequently negative despite radicular leg pain...

In this article, we drew from a recently completed etiological systematic literature review (SLR) using a mixed methods approach (1) to explain the process for analyzing and synthesizing the results of 201 sources and (2) to comment on the use of Creswell et al’s criteria for mixed methods approaches. We provided a detailed process description of the steps involved in this SLR, and demonstrated...

This work describes the application of digital single lens reflex (SLR) cameras in astronomy science. A definition of the term raw file format is given. As with formats like FITS or TIFF, the CR2 file format is explained beeing a disclosed, and well documented raw file format. Results from raw image file decomposition with different software tools, and a comparison of imaging with a digital SLR...

Coastal protection design heights typically consider the superimposed effects of tides, surges, waves, and relative sea-level rise (SLR), neglecting non-linear feedbacks between these forcing factors. Here, we use hydrodynamic modelling and multivariate statistics to show that shallow coastal areas are extremely sensitive to changing non-linear interactions between individual components caused ...

Bioinformatics research depends on high-quality databases to provide accurate results. In silico experiments, correctly performed, may prospect novel discoveries and elucidates pathways for biological experiments through data analysis in large scale. However, most biological databases have presented mistakes, such as data incorrectly classified or incomplete information. Also, sometimes, data m...

Various methods for kinematic and reduced-dynamic precise orbit determination (POD) of Low Earth Orbiters (LEO) were developed based on zeroand double-differencing of GPS carrier-phase measurements with and without ambiguity resolution. In this paper we present the following approaches in LEO precise orbit determination: – zero-difference kinematic POD, – zero-difference dynamic POD, – double-d...

Sea-level rise (SLR) from global warming may have severe consequences for coastal cities, particularly when combined with predicted increases in the strength of tidal surges. Predicting the regional impact of SLR flooding is strongly dependent on the modelling approach and accuracy of topographic data. Here, the areas under risk of sea water flooding for London boroughs were quantified based on...

Purpose: This study aimed to investigate the electromyographic activities and balance of Vastus Medialis Obliquus (VMO) and Vastus Lateralis (VL) muscles during Straight Leg Raise (SLR) in individuals with and without Patellofemoral Pain Syndrome (PFPS). Methods: Through an analytical case-control study, 26 persons with PFPS and 26 healthy subjects were recruited by non-random and convenience ...

[Purpose] The purpose of this study was to clarify fundamental changes induced by lower trunk muscle contraction during single-leg standing. [Subjects and Methods] Ten healthy normal males participated in this study. All subjects could accurately perform lower trunk muscle contraction-type Abdominal Expansion (AE), Abdominal Bracing (AB), and Abdominal Cave-in (AC). The alignment and position o...
