DIscuSsIoN The normal occlusion pressure response to elastic loads in COPD patients in whom the response to flow loads is impaired indicates that the diminished response to flow loads cannot be explained by decreased muscle performance or fatigue. Rather, this phenomenon appears to represent a specific defect perhaps in the recognition of the resistive load by mechanoreceptors or in the interpr...

the increasing world demand for fish cannot be met by capture fisheries. aquaculture production is increasing and nowadays cage culture has an important role in meeting the world’s fish demand. the design of the physical structure of a cage is determined by the oceanographic conditions of the culture site. each design is site-specific and knowledge of the topography, wind force and direction, p...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

in order to assess the efficacy of hysteroscopic endometrial ablation and factors which are important in it's success, a prospective, randomized study was performed in shiraz university hospitals between sep. 1995 to feb. 1998. 50 patients with chief complaints of menorrhagia that were in reproductive age (25- 50 years) and had shown no response to medication and d&c; underwent endometrial...

in this paper, we investigated the necessity and effects of optimal control methods in the stability and performance of a micro-grid that operates in islanded mode. the micro-gird is consisted of a combine heat and power (chp), a capacitor bank (cb), photovoltaic panel (pv) as power generation sources. in addition, battery and the building electricity and thermal load are placed on the load sid...

modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...

BACKGROUND Loads acting on scoliotic spines are thought to be asymmetric and involved in progression of the scoliotic deformity; abnormal loading patterns lead to changes in bone and disc cell activity and hence to vertebral body and disc wedging. At present however there are no direct measurements of intradiscal stresses or pressures in scoliotic spines. The aim of this study was to obtain qua...

Abnormal loads due to natural events, implementation errors and some other issues can lead to occurrence of progressive collapse in structures. Most of the past researches consist of 2- Dimensional (2D) models of steel frames without consideration of the floor system effects, which reduces the accuracy of the modeling. While employing a 3-Dimensional (3D) model and modeling the concrete slab sy...

Cholinesterase Activity in Female Greenhouse Workers—Influence of Work Practices and Use of Oral Contraceptives: Jesper B NIELSEN, et al. Environmental Medicine, University of Southern Denmark—Objectives—Associations between serum butyryl cholinesterase activity in female greenhouse workers and information from a questionnaire on work, use of personal protective equipment, and lifestyle were ev...

INTRODUCTION It has been suggested that abnormal lower extremity kinematics during running are related to patellofemoral pain (PFP). Specifically, during the first half of stance when the knee is loaded, excessive internal rotation of the femur may result in lateral patellae maltracking [1,2]. Similarly, the patellofemoral joint may also be influenced by excessive knee valgus, which may be part...
