Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...

synthetic hydroxyapatite (ha) is the most helpful because of its similarity to natural bone in both crystalline structure and chemical composition. recently, fluoridated hydroxyapatite (fha) has been developed in dental and orthopedic application because it has lower solubility than pure ha, while maintaining the comparable bioactivity and biocompatibility. the aim of this study was to synthesi...

Similarities and distinctions have been pointed out between ICA and traditional multivariate methods such as factor analysis, principal component analysis and projection pursuit. In this paper, a new important connection between ICA and traditional factor analysis is made. The key of the connection is “factor rotation.”

a r t i c l e i n f o There is a wide consensus in the literature that gender differences can be observed in tasks measuring mental rotation ability. A possible explanation of this finding is the presence of gender differences in the processing speed of mental rotation tasks. In two studies, we investigated the dimensionality and the presence of gender differences in mental rotation processing ...

A two-stage embossing technique for fabricating microchannels for microfluidic devices is presented. A micromachined aluminum mold is used o emboss a polyetherimide (PEI) substrate with a relatively high glass transition temperature (T ). The embossed PEI is then used as a mold for g mbossing an amorphous polyethylene terephthalate (APET) substrate with a lower Tg. The resulting APET substrate ...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...

Background. This study aims to analyze the movement of backhand and forehand smash stroke techniques in badminton in three dimensions using a kinematics approach. Objectives. The obtained results were analyzed using a descriptive and quantitative approach. Methods. Furthermore, 24 male badminton players from the university student activity unit with an average age of 19.4 ± 1.6 years, height ...
