The objective of this research was to evaluate the clinical benefits of using a mini-instrument during endoscopic thyroidectomy via a breast approach (ETBA). Surgery-related indices and cosmetic results were compared for 20 patients underwent ETBA with a mini-instrument (ETBA-m) and 20 patients who underwent standard ETBA (sETBA). Patients were closely matched in terms of age, gender, tumor siz...
Rhodococcus sp. RHA1 induces two biphenyl dioxygenases, the BphA and EtbA/EbdA dioxygenases, during growth on biphenyl. Their subunit genes were expressed in R. erythropolis IAM1399 to investigate the involvement of each subunit gene in their activity and their substrate preferences. The recombinant expressing ebdA1A2A3etbA4 and that expressing bphA1A2A3A4 exhibited 4-chlorobiphenyl (4-CB) tran...
The adsorption and the redox behaviour of thrombine binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K and voltammetric behaviour of TBA and eTBA. ...
The adsorption and the redox behaviour of thrombin-binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K(+), and voltammetric behaviour of TBA and eTB...
زمینه و هدف: با پیشرفت تکنولوژی، انسان، تجهیزات، محیط زیست، مواد و اعتبار سیستم در معرض شرایط خطرناک قرار گرفته است. با توجه به سهم 3/32 درصدی صنعت در بخش اشتغال و رشد سریع صنایع تولید فلزات اساسی در این عرصه، کنترل حوادث و هزینه های مربوطه امری ضروری است.با توجه به اهمیت نیروی انسانی درتوسعه پایدار، مطالعه حاضر به منظور شناسایی و ارزیابی ریسک با رویکرد کنترل حوادث، در یک صنعت ریخته گری انجام ...
زمینه و هدف: امروزه استفاده از دستگاه تی بی ام در عملیات حفاری مکانیزه، بویژه حفاری تونل های عظیم و با سرعت عملیاتی بالا، رایج شده است. در سالهای اخیر در پروژه های تونل سازی خصوصا در عملیات حفاری با ماشین های تی بی ام حوادث زیادی بوقوع پیوسته است. کنترل مخاطرات می بایست از طریق فرایند مدیریت ریسک صورت پذیرد. این مطالعه با هدف بررسی ریسک عملیات حفاری مکانیزه بااستفاده از دستگاه تی بی ام، در یکی ...
Introduction: The steel industry is known as the most important consumer of energy and fuel. In doing so, ensuring safety of energy sources of a country needs to expect the risks analysis in order to select a comprehensive approach. This study aimed to identify the energy consumption and control measures available in the Hot Rolling Kavir Steel Complex and to conduct risk assessment by Energy...
background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...
Background and aims Each year many people die from accidents at work. Enormous costs of these accidents have forced specialists looking for ways to prevention of accidents. This study focuses on evaluation the safety of glucose production unit by energy trace and barrier analysis (ETBA) and present approaches to prevention of accidents. Methods Steps to perform ETBAmethod was completed ...
