Density of catalytic organisms can determine the biodegradation capacity and specific biodegradation rate (SBR). A new index, biodegradation capacity utilization (BCU, %), was developed for estimating the extent of actual biodegradation of a gas compound over the full capacity. Three methanotrophic cultures were serially diluted (1-1/25), and methane SBR and BCU were measured. Consistently, bio...
OBJECTIVES Upper gastrointestinal (UGI) bleeding carries high morbidity and mortality. The use of a bleeding care pathway (BCP) may improve outcomes, but the results are inconsistent in various studies. METHODS A BCP for patients with UGI bleed with admission in a bleeding care unit (BCU) has been in use at our hospital since 2005. Prior to this, a high dependency unit was used for management...
BACKGROUND Bacterial contamination is a life-threatening risk of blood transfusion, especially with platelet (PLT) transfusions. Bacterial culturing (BCU) of PLTs as well as pathogen reduction (PRT) reduce the likelihood of such contamination. The cost-effectiveness (CE) of these interventions was analyzed after the introduction of the diversion pouch during blood collection. STUDY DESIGN AND...
The oriented diameter of a bridgeless connected undirected (bcu ) graph G is the smallest diameter among all the diameters of strongly connected orientations of G. We study algorithmic aspects of determining the oriented diameter of a chordal graph. We (a) construct a linear-time approximation algorithm that, for a given chordal bcu graph G, finds a strongly connected orientation of G with diam...
This paper shows that under some circumstances the so called BCU method may not be able to find the true CUEP for a specific fault-on trajectory of a power system. The reasons to that malfunction are analysed, and a methodology than can improve the capability of the BCU method to successfully find the CUEP is presented. Finally, several applications of the proposed method to power electrical sy...
Bone-conducted ultrasound (BCU) is perceived even by the profoundly sensorineural deaf. We have developed a novel hearing-aid using BCU perception (BCU hearing aid: BCUHA) for the profoundly deaf. In the BCUHA, ultrasonic sinusoids of about 30 kHz are amplitudemodulated by speech and presented to the mastoid. Generally, two sounds are perceived: one is a high-pitched tone due to the ultrasonic ...
Recent several years have witnessed the surge of asynchronous (async-) parallel computing methods due to the extremely big data involved in many modern applications and also the advancement of multi-core machines and computer clusters. In optimization, most works about async-parallel methods are on unconstrained problems or those with block separable constraints. In this paper, we propose an as...
Human listeners can perceive speech signals from a voicemodulated ultrasonic carrier which is presented through a boneconduction stimulator, even if they are sensorineural hearing loss patients. As an application of this phenomenon, we have been developing a bone-conducted ultrasonic hearing aid (BCUHA). This research examined whether formant space and F0 can be cues of speaker discrimination i...
در این مقاله روش ترکیبی شبیه سازی زمانی و BCU1 به منظور بررسی پایداری گذرای سیستم های قدرت به روش تابع انرژی گذرا (TEF)2 در چهارچوب مرجع مرکز اینرسی(COI)3 ارائه می شود. در روش BCU از مرز پایداری یک سیستم کاهش یافته که تنها در زیر فضای زاویه تعریف می گردد به عنوان تقریبی محلی از مرز پایداری سیستم اصلی استفاده می شود به طوریکه تقریب مرز پایداری سیستم کاهش یافته ساده تر می باشد. برای این منظور اب...
