تعیین توان اراضی بهمنظور استفاده بهینه از سرزمین و جلوگیری از تخریب در اثر استفاده نامناسب از اراضی گامی مؤثر در راهبرد توسعه پایدار است. با توجه به اهمیت موضوع، در این مطالعه به ارزیابی توان اکولوژیک حوضه آبخیز بابلرود جهت کاربری مرتعداری با استفاده از روش فرایند تحلیل سلسله مراتبی و سامانه اطلاعات جغرافیایی پرداخته شد. به این ترتیب که ابتدا سلسله مراتب فرایند ارزیابی تشکیل شد و وزن معیارها ...
Today, we o perate in a networked world, where organizations frequently resort to offshoring, such that work gets accomplished by a globally distributed workforce, whether inside or outside the organizational boundaries. Much of the past research on offshoring has focused on economic rationale and benefits as well as risks associated with offshoring. Offshoring leverages human capital in differ...
OBJECTIVE To evaluate the efficacy of narrow band imaging (NBI) cystoscopy associated with bipolar plasma vaporization (BPV) in cases of large nonmuscle-invasive bladder tumors (NMIBTs) compared with white light cystoscopy (WLC) and monopolar transurethral resection of bladder tumors (TURBTs). METHODS A total of 220 cases with ≥ 1 bladder tumor >3 cm determined by abdominal ultrasonography, c...
اختلالات نواحی گسترده در شبکه قدرت به دلیل اندازهی بزرگ و پیچیدگی سیستم قدرت، یک چالش برای صنعتهای مختلف هستند. هنگامیکه یک اختلال اصلی در سیستم قدرت رخ میدهد، عملیات کنترل و حفاظت برای توقّف فروپاشی سیستم قدرت، بازیابی سیستم قدرت به حالت نرمال و حداقل کردن تأثیر اختلالات نیاز است. عملیات کنترل حاضر برای یک اختلال پیشرفته و سریع طراحی نشدهاند و ممکن است خیلی ساده باشند. به علاوه نرم افزارهای ش...
We introduce a biologically motivated dynamical principle of sequential memory which is based on winnerless competition (WLC) of event images. This mechanism is implemented in a two-layer neural model of sequential spatial memory. We present the learning dynamics which leads to the formation of a WLC network. After learning, the system is capable of associative retrieval of prerecorded sequence...
We study the effect of morphology on the low-temperature behavior of superconducting nanowires which vary in length from 86 nm to 188 nm. A well-defined superconductor-insulator transition is observed only in the family of homogeneous wires, in which case the transition occurs when the normal resistance is close to h/4e. Inhomogeneous wires, on the other hand, exhibit a mixed behavior, such tha...
Efficacy and Safety of Hexaminolevulinate Fluorescence Cystoscopy in the Diagnosis of Bladder Cancer
PURPOSE The aim of this study was to evaluate the efficacy and safety of hexaminolevulinate fluorescence cystoscopy in the diagnosis of bladder cancer. MATERIALS AND METHODS In a prospective design, we included patients who had a bladder lesion suggesting bladder cancer. Patients with massive hematuria, urethral Foley catheter insertion, chronic retention state, or urinary tract infection wer...
PURPOSE The purpose of this study was to calculate the operating characteristics of narrowband imaging (NBI) cystoscopy versus traditional white light cystoscopy (WLC) in common clinical scenarios involving suspicion of bladder urothelial carcinoma (UC). MATERIALS AND METHODS Sixty-three consecutive patients initially underwent WLC and then NBI in a single session for evaluation of microscopi...
BACKGROUND The aim of the present cross-sectional study was to examine work- and nonwork- related factors and physical and mental health outcomes associated with combined time- and strain-based work-life conflict (WLC) among adult employees living and working in Switzerland as well as possible gender differences in this regard. METHODS The data used for the study were taken from wave 6 of the...
We use a white-light continuum (WLC) Z-scan technique to measure the degenerate two-photon absorption spectrum and associated dispersion of the nonlinear refraction in ZnSe. The spectral components of the WLC source are separated by using a narrow band variable filter to minimize nondegenerate nonlinearities. We observe a change in sign of the ultrafast nonlinear refractive index around 0.7 of ...
