.چکیده:در تجزیه لیگنین، مجموعه¬ای از آنزیم¬ها تحت عنوان لیگنیناز نقش دارند. لاکاز به علت ویژگی¬های خاص خود در بین آنزیم¬های تجزیه¬کننده لیگنین از اهمیت خاصی برخوردار است. از ویژگی¬های لاکاز،اکسیداسیون انواع متعدد سوبستراها، تحمل گرمایی بالا، داشتن pH ایزوالکتریک اسیدی است. شناسایی میکروارگانسیم¬های جدید با قدرت تولید و ترشح بالاتر این آنزیم صنعتی از اهمیت انکارناپذیری برخوردار است. لذا در این ت...

Introduction Lactose malabsorption arises from lactase deficiency and may lead to lactose intolerance - gastrointestinal symptoms after lactose ingestion. Occurrence and severity of the symptoms are influenced by many factors, including the dose of lactose and the intensity of its colonic fermentation to short chain fatty acids and gases. Material and methods The hydrogen breath test (HBT) af...

In this paper, we report the development of a high breakdown voltage InGaP/GaAs HBT process for low-to-mid power and high-voltage power amplifier operation. To achieve the high-breakdown InGaP HBT, two different collector designs and collector-etch processes were investigated. The first device process approach uses a thick GaAs collector with low n doping. The process challenges and considerati...

We show that a consistent hydrodynamic description of soft-hadronic oneand two-particle observables (the HBT radii) studied in the relativistic heavy-ion collisions at RHIC may be obtained if one uses the Gaussian energy density profile as the initial condition. The transverse-momentum spectra, the elliptic flow coefficient v2, and the pionic azimuthally sensitive HBT radii are successfully rep...

The relationship between pion and kaon space-time freeze-out distributions and the HBT radius parameters in high-energy nucleus-nucleus collisions is investigated. We show that the HBT radius parameters in general do not reflect the R.M.S. deviations of the single particle production points. Instead , the HBT radius parameters are most closely related to the curvature of the two-particle space-...

ABSTRACT — The recently developed LS HBT model was evaluated with extensive Power spectrum, Load pull and Inter-modulation investigations. Some changes of the model were made, like improved temperature, leakage resistance and capacitance models. The corresponding changes were implemented in ADS as SDD. Important future of the model is that the model parameters are organized to use directly meas...

Although research on Health Behavior Theory (HBT) is being conducted at a rapid pace, the extent to which the field is truly moving forward in understanding health behavior has been questioned. This issue is examined in the current article. First, we discuss the problems within the HBT literature. Second, we discuss the proliferation of HBT and why theory comparison is essential to this area of...

In this study, an accurate temperature prediction model is proposed for GaAs HBT, which considers both the bias voltage and current rather than power consumption only. The increase in closely related to heat source property, leads a complex interaction between lattice vibration uneven distribution of electric field density. To improve accuracy stability model, machine learning method Extreme Le...
