the structural slenderness ration (height/ with) is one of the title that can be discussed in quake design of building. but unfortunately, in  iranian code isn’t mention this mater.in this article, bending and bracying structures system are chosen with slenderness ratio 2 upto 6. (11, 17, 23, 29, 35 stage).all of structure are analysed and designed in linear method, then analysed in unlinear me...

BACKGROUND Many years of bracing represent a burden to the patients. Early weaning may be the result of poor compliance, but may also be planned in patients with a long expected treatment time and a reduced stable primary curve during bracing. The aim of the present cohort study was to compare curve size, health related quality of life and surgical rates at long-term follow-up after ordinary br...

[Purpose] The purpose of this study was to examine the effects of hollowing and bracing exercises on cross-sectional areas of abdominal muscles. [Subjects] Thirty healthy female adults participated in this study. The exclusion criteria were orthopedic or neurologic diseases. [Methods] The subjects of this study were assigned randomly to one of two groups, each with 15 people. Each group perform...

BACKGROUND Scoliotic curves do not necessarily stop progressing at skeletal maturity. The factors that influence curve behavior following bracing are not fully determined. Our objectives were to evaluate the loss of the scoliotic curve correction in a cohort of patients treated with bracing during adolescence and to compare the outcomes of 18 versus 23 h of bracing at a mean of 25 years post br...

BACKGROUND Bracing has been shown to decrease significantly the progression of high-risk curves to the threshold for surgery in patients with adolescent idiopathic scoliosis (AIS), but the treatment failure rate remains high. There is evidence to suggest that Schroth scoliosis-specific exercises can slow progression in mild scoliosis. The aim of this study was to evaluate the efficacy of Schrot...

The main girders of the I-section steel-concrete composite twin girder bridge is usually connected together by frame cross bracing. When with welding, flat plates for stiffening can be used to strengthen connection ensure effective transfer forces between two. In this paper, finite element simulation method study influence plates. results show that, compared structure without stiffening, when s...

agricultural sustainability refers to the ability of a cropping system to produce, without causing irreversible damage tothe ecosystem. there is an increasing need to view cropping systems and identify management practices in a holisticindicator-based impact assessment. the main objective of this study was to compare and rank the cropping systems of themarvdasht plain in fars province; in order...

The Ponseti method for the management of idiopathic clubfoot has recently experienced a rise in popularity, with several centers reporting excellent outcomes. The challenge in achieving a successful outcome with this method lies not in correcting deformity but in preventing relapse. The most common cause of relapse is failure to adhere to the prescribed postcorrective bracing regimen. Socioecon...

Background A recently published NIH-funded study named “Bracing in Adolescent Idiopathic Scoliosis Trial” (BrAIST) affirmed the efficacy of bracing for moderate adolescent idiopathic scoliosis (AIS) and reduced surgical recommendations in braced patients. The implications of this study are numerous. BrAIST affirms the value of bracing, but also confirms the importance of wear time, and points t...

Methods We retrospectively observed 13 patients with the diagnosis of LS. 7 of them needed bracing because of lumbar kyphosis, while the others were treated only with physical exercises to control pain and prevent deformity. All patients treated with bracing (3 males and 4 females, average age 13.5 years) presented at first observation with back pain, lumbar kyphosis, and a radiographic image o...
