Abstract:

The effect of size on longitudinal shear strength has been well established for Douglas-fir glued–laminated (glulam) timber beams. The present study examined whether this phenomenon exists in glulam beams made of spruce. The experiment consisted of three projects in which beams of various sizes were tested under concentrated mid-span load. The project A beams had clear spruce webs and white elm flanges with cross-sectional dimensions varying from 25 × 25 mm to 75 × 75 mm. The project B beams had spruce glulam webs with Douglas-fir flanges; cross sections ranged from 20 × 100 mm to 90 × 200 mm.

The paper presents development of multi-segment lumbar structure based on the human spine. The research is performed within the project based on development of socially acceptable robot named "SARA". Two approaches for spine realization of humanoids exist: multi-joint viscoelastic structures (5-10 joints) that have variable flexibility and structures that consist of one joint - torso/waist joint, which has low elasticity and high stiffness. We propose multi-joint flexible structure with stiff, low backlash and self-locking mechanisms that require small actuators. Based on kinematic-dynamic req

Male sexual function in mammals is controlled by the brain neural circuits and the spinal cord centers located in the lamina X of the lumbar spinal cord (L3–L4).

Sexual experiences can influence male sexual activity in rats. However, how this experience affects the brain–spinal cord neural circuits underlying male sexual activity remains unknown. Focusi

Abstract:

BackgroundPain of lumbar facet-joint origin is a common cause of low back pain in adults and may lead to chronic pain and disability, with associated health and socioeconomic implications. The socioeconomic burden includes an inability to return to work resulting in loss of productivity in addition to direct and indirect health-care utilisation costs. Lumbar facet-joints are paired synovial joints between the superior and inferior articular processes of consecutive lumbar vertebrae and between the fifth lumbar vertebra and the sacrum. Facet-joint pain is defined as pain that arises from any st

Abstract:

In today’s automotive market, comfort is huge selling point of a vehicle. Priority is given by buyers to how comfortable a seat feels during purchase decisions. The measure of comfort is harmonious mix of many aspects such as human ergonomics and physiological factors. However, a gap still exists between objective and subjective measures due to lack of emphasis by past researchers. This is particularly obvious in the lumbar support feature that has still not been able to address the health problems related to driving. This project focuses on bridging the gap by giving users the ability to defi

Abstract:

Palpation is an essential skill of manual therapy. Clinical techniques of physical therapy usually assume that the movement direction of palpating spinous process (SP) is the direction of the vertebral body center (VBC). This study investigated the distance [SP–projected VBC (PVBC)] between the surface palpation of the five SPs and the radiographically projected vertebral center locations (PVBC) on the skin of the lumbar spine in 37 patients with low back pain (LBP). The measurement of SP–PVBC was intended to describe if palpation on SPs could explain the positions of the VBC. The SP–PVBC dist

Abstract:

Commercial fishing is a job characterized by long hours in an unpredictable natural environment and variable demands placed on the musculoskeletal system, requiring strength, coordination, and endurance. The focus of this project was in the quantification of the biomechanical stresses placed on the lumbar spine during the work activities of commercial crab fishermen. The Continuous Assessment of Back Stress (CABS) methodology was used to develop distributions describing the amount of time that each of the three workers on a three-man crabbing crew spend at various levels of spine stress.

The semantic-motivational and etymological analysis of the Russian dialectal designations of lumbar and lumbar pain is presented. The material was extracted from dictionaries of Russian dialects, from unpublished card files of the Ural University toponymic expedition to the territories of the Russian North and the Upper Volga region, as well as folklore and ethnographic sources related to folk medicine. The main semantic-motivational models underlying the designation of the lower back, which can reflect the idea of the “topography” of this part of the body, correlation with adjacent bodily are

OBJECTIVELumbar decompression without arthrodesis remains a potential treatment option for cases of low-grade spondylolisthesis (i.e., Meyerding grade I). Minimally invasive surgery (MIS) techniques have recently been increasingly used because of their touted benefits including lower operating time, blood loss, and length of stay. Herein, the authors analyzed patients enrolled in a national surgical registry and compared the baseline characteristics and postoperative clinical and patient-reported outcomes (PROs) between patients undergoing open versus MIS lumbar decompression.METHODSThe author

Abstract:

ABSTRACT Objective: Facet joints are true synovial joints, which derive their nerve supply from the sinuvertebral or recurrent nerve of Luschka as well as the posterior primary division of the corresponding spinal nerve. Diagnosis of low-back pain originating in the facet joints is difficult, and has traditionally relied upon invasive tests. To aid in the clinical diagnosis of this condition, the senior author described a new clinical sign. The following research project was designed to test the utility of this sign in the diagnosis of lumbar facet joint pain. Methods: We conducted a prospecti

Abstract When confronted with a patient with a brachial plexus injury, how often as neurosurgeons do we consult and atlas to confirm the anatomy of the brachial plexus and then attempt to establish the location of the lesion? Similar difficulties are encountered with lumbar and sacral plexus lesions. In a project organized to assist the neurosurgeon in this time-consuming task, a computer program that can rapidly determine the site of a lesion in a brachial, lumbar, or sacral plexus injury was created.

Abstract:

A collection of neurons in the upper lumbar spinal cord of male rats projects to the lower lumbar spinal cord, releasing gastrin-releasing peptide (GRP) onto somatic and autonomic centers known to regulate male sexual reflexes such as erection and ejaculation. Because these reflexes are androgen dependent, we asked whether manipulating levels of androgen in adult rats would affect GRP expression in this spinal center. We found that castration resulted, 28 d later, in a profound decrease in the expression of GRP in the spinal cord, as reflected in immunocytochemistry and competitive ELISA for t

To assess the risk of osteoporosis, the results of Caucasian and Asian women were compared with those of a reference Caucasian population supplied by Lunar. 2.
