Exposure to ion and micrometeoroid bombardment in the space environment causes physical and chemical changes in the surface of an airless planetary body. These changes, called space weathering, can strongly influence a surface’s optical characteristics, and hence complicate interpretation of composition from reflectance spectroscopy. Prior work using data from the Dawn spacecraft (Pieters, C.M....
The binding sites on human IgG1 for human Fc gamma receptor (Fc gamma R) I, Fc gamma RIIa, Fc gamma RIIb, Fc gamma RIIIa and neonatal FcR have been mapped. A common set of IgG1 residues is involved in binding to all Fc gamma Rs, while Fc gamma RII and Fc gamma RIII utilize distinct sites outside this common set. In addition to residues which abrogated binding to the Fc gamma R, several position...
BACKGROUND Despite poor evidence and high costs, fibrinogen concentrate (FC) represents one of the most frequently used hemostatic agents in exsanguinating trauma. The aim was to assess whether the administration of FC in severely injured patients was associated with improved outcomes. METHODS Patients documented in the Trauma Registry of the German Society for Trauma Surgery (primary admissi...
Determination of the optimal design experiments that enables efficient parametrisation fuel cell (FC) model with a minimum data-set is one key prerequisites for minimizing costs and effort procedure. To efficiently tackle this challenge, paper present an innovative methodology based on electrochemical FC model, parameter sensitivity analysis application D-optimal plan. Relying consistent method...
We studied the physical behavior of PdO nanoparticles at low temperatures, which presents an unusual clearly related to macroscopic quantum tunneling. The samples show a tetragonal single phase with P42/mmc space group. Most importantly, particle size was estimated about 5.07 ± 1.97 nm. Appropriate techniques were used determine characteristic these nanoparticles. most important aspect this stu...
در مناطق خشک و نیمه خشک، خشکی از مهمترین تنش های محیطی است که اثرات نامطلوبی روی جوانه زنی و بنیه اولیه بذرها دارد. جهت بررسی واکنش اکوتیپ های متفاوت گیاه ماریتیغال به تنش خشکی و نیز تاثیر پرایمینگ بر تقویت بنیه اولیه بذرهای آن، آزمایشات جوانه زنی در قالب فاکتوریل بر پایه طرح کاملا تصادفی انجام شد. در آزمایش اول فاکتور خشکی در 4 سطح (fc، fc 75% ، fc 50% و fc 25%) و فاکتور منبع بذر (اکوتیپ) نیز ...
نیترات سازی یکی از فعال ترین فرآیندهای زیستی در خاک هایی است که کود نیتروژن آمونیومی دریافت کردهاند. سرعت این فرآیند تحت تأثیر غلظت آمونیوم، دما، رطوبت خاک، غلظت o2، ph، ec و اثرات متقابل این عوامل قرار دارد. در تحقیق حاضر تاثیر غلظت آمونیوم و رطوبت بر میزان نیترات سازی و نیز سینتیک این فرآیند در دو نمونه خاک a و b به ترتیب از دو منطق مرند و اهر مورد مطالعه قرار گرفت. در مرحله اول، آزمایشی به ...
Fc receptors (Fc R) trigger inflammatory reactions in response to immunoglobulinopsonized pathogens and antigen-antibody complexes. The coordinate expression of activating and inhibitory Fc R ensures the homeostasis of immune complex-driven inflammatory responses. In this study, we used antibodies with preferential binding for activating Fc RIIa and inhibitory Fc RIIb receptors to investigate t...
The involvement of Fc- and Fc+ T cells, separated on the fluorescence-activated cell sorter, in proliferative and cytotoxic responses to alloantigens was examined. The cytotoxic lymphocytes generated by in vivo exposure to allogeneic tumor cells were shown to express the Fc receptor. The proliferative responses to alloantigen exposure in mixed lymphocyte cultures was equivalent in intensity for...
