Abstract A number of destructive and non-destructive tests were conducted on rock samples collected from various zones in northern Iraq. So far, for Iraqi rocks, few studies have correlated Schmidt hammer rebound ( R ) with both unconfined compressive strength (UCS) Brazilian tensile (BTS). In this study, the objective is to develop a relationship between surface hardness (rebound number) BTS d...
Introduction: Communication between mobile phones and antenna BTS (Base Transceiver station) is carried by electromagnetic waves that have energy, according to their nature. Increasing use of mobile phones because of the proliferation of antennas the concerns about them are proposed in society. In the present study the correlation between distance from the BTS antennas and the ...
The impact of several land surface models (LSMs) and microphysics (MP), planetary boundary layer (PBL), schemes on the accuracy simulated brightness temperatures (BTs) from water vapor (WV) sensitive bands was examined via comparison with observations GOES-16 Advanced Baseline Imager. Nine parameterization configurations were evaluated. Analysis revealed that, compared to Thompson MP scheme, Na...
چکیده: در این مقاله، یک آنتن جدید چهارتایی شکافی فشرده برای بهکارگیری در گیرندههای GPS ارائه شده است. ساختار آنتن از چهار عنصر تشعشعی شکافی نیمطولموج با یک نوار اتصال کوتاه تشکیل شده است که با اختلاف فازی 90 درجه نسبت به یکدیگر تغذیه میشوند. ابعاد آنتن ارائه شده 3mm24Î24Î12 است که در مقایسه با بسیاری از آنتنهای ارائهشده تاکنون بسیار کوچکتر است. همچنین آنتن پیشنهادی دارای خلوص قطبش راست...
OBJECTIVE The purpose of this study was to analyze bladder tumor (BT) associated with renal pelvic and/or ureteral tumor (RUT), with emphasis on the relationship between the grade and stage of these tumors. METHODS We reviewed 77 cases of RUT operated upon at our hospital during the last 14 years. We herein define stage T1b tumor as invasive since this stage of tumor is considered to have a d...
INTRODUCTION The purpose of the quality standards document is to provide healthcare professionals, commissioners, service providers and patients with a guide to standards of care that should be met for home oxygen provision in the UK, together with measurable markers of good practice. Quality statements are based on the British Thoracic Society (BTS) Guideline for Home Oxygen Use in Adults. M...
Department of Obstetrics and Gynaecology, Prince of Wales Hospital, Shatin, Hong Kong Pap smear screening is a multi-step process that involves recruitment of patients, taking smear, making and reading slides and issuing reports to alert clinicians to take appropriate action. In the last decade, innovative technologies including liquid base cytology, automated screening and human papilloma viru...
Introduction These guidelines have been developed at the request of the Standards of Care Committee of the British Thoracic Society (BTS). Two particular problems have emerged since the previous BTS guidelines were published. 2 Firstly, there have been many cases reported recently of atypical mycobacteria causing contamination of bronchoscopes leading to pseudoinfections. Secondly, toxicity fro...
Sexually dimorphic breeding tubercles (BTs) are keratinized epidermal structures that form clusters on the dorsal surface of the anterior rays of zebrafish male pectoral fins. BTs appear during sexual maturation and are maintained through regular shedding and renewal of the keratinized surface. Following pectoral fin amputation, BT clusters regenerate after the initiation of revascularization, ...
The present paper looks for kinematic similarities between whole-body and arm movements executed in the sagittal plane. Eight subjects performed sit-to-stand (STS) and back-to-sit (BTS) movements at their preferred speed in the sagittal plane. Kinematics analysis focused on shoulder motion revealed that STS was composed of a straight, forward displacement followed by a curved, upward displaceme...
