Due to the high cost of laboratory testing, many researchers are considering developing methods predict behavior unreinforced and reinforced wood beams. This work aims create either numerical or analytical models useful for extrapolating already conducted tests other schemes/materials used as reinforcement. In case timber structures, due complexity timber, this task is difficult. The first part...

objective: to evaluate the increased rate of cesarean section in recent decades and natural desire of women probably due to social, economic& cultural issues in our country. while that in many cases, vaginal delivery can be replaced by unnecessary cesarean. in the absence of need the trend of cesarean section has implications for both future healthy populations and the equitable distribution of...

A new method for three-dimensional image formation is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer. The method can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle than from conventional digital holography u...

abstract background: one of the most important problems in surgical patients is anxiety before surgery. teach-back method is an interactive training method that can lead to increase understanding and knowledge of the patients. the aim of this study is survey the effect of teach back- method on surgical anxiety in primiparous cesarean section women. methods: this study is a randomized clinical t...

in this descriptive study, we investigated how mother and infant rooming method after delivery are implementing in academic hospitals of tehran university of medical sciences in 1993. in this research, fifteen wards include post delivery ward, surgical ward that mothers after cesarean section hospitalized in them and jointed ward that mothers who underwent cesarean section and normal vaginal de...

in this paper, we present the windsurfer approach for the design of adaptive robust control systems. In section 1 we review the weakness of traditional adaptive control systems. In section 2 we illustrate the idea of the windsurfer approach by considering an adaptive model matching problem. In section 3, we show how a closed-loop sysrem identification problem associated with the windsurfer appr...

. This project was funded by NIDA 1R01DA039122 01 (Durbin). . Under Section 2.4.2 Defensive reactivity measures, our startle magnitudes were only log-transformed, not t-scored and log-transformed. So, the last sentence of the first paragraph should read “Therefore, startle magnitudes were log-transformed”. . In the Supplemental methods and materials, section titled “defensive reactivity measure...
