introduction h syndrome (omim 612391) is an autosomal recessive disease with some features such as hyperpigmentation, hypertrichosis, heart anomalies, hepatosplenomegaly, hearing deficit, hypogonadism, short stature, flexion contracture of fingers and toes and hypertriglyceridemia. case presentation a 17-year-old boy with hyperpigmented, hypertrichotic and indurated seborrheic keratosis-like cu...
objective(s): htlvi-1 is the first human retrovirus with limited endemic regions in the world. the epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in htlv-i-associated diseases. among the genes are involved in htlv-i infection, the role of human leukocytes antigen (hla) have been studied in different population. in the pre...
The atomically laminated Ti 2 AlC, 3 AlC and Cr MAX phases, with A = Al, form adherent, passivating ? -alumina, Al O , oxide scales when heated in air. effect of solid solutions on the layers affecting oxidation kinetics remains a subject open research. Herein we synthesize dense bulk polycrystalline 1?x Ga x C (x ? 0.4) solid-solution investigate its isothermal ambient air, 1000 °C–1300 °C tem...
فرض کنید a و b دو c^{*}-جبر یکدار باشند به طوری که حداقل یکی از آن ها از رتبه ی حقیقی صفر باشد. در این صورت به بررسی نگاشت خطی یکدار و پوشای ?: a ? b که حافظ پیمانه کمین کاهش یافته، عناصر منظم و طیف تعمیم یافته است، می پردازیم. همچنین به بررسی برخی نتایج روی ( b(h (فضای عملگرهای خطی کراندار) در حالتی که h یک فضای هیلبرت از بعد نامتناهی است، می پردازیم.
اگر ? نگاشت جمعی پوشا بین دو جبر عملگری باشد که در رابطه خاصی صدق می کند تحت شرایط خاص نشان می دهیم ? یک همومورفیسم جردن ضرب شده با یک عضو مرکزی است. در حالت خاص اگر k و h دو فضای هیلبرت با بعد نامتناهی(حقیقی یا مختلط) باشند(a=b(hو(b=b(kآنگاه عدد ثابت غیر صفر c و نگاشت وارونپذیر خطی یا مزدوج خطی u از h به k وجود دارند که در شرط خاصی صدق می کند.
Abstract Refractory ‘stuffed’ pyrochlores such as Gd 2 TiO 5 are of interest for nuclear applications, including matrices actinide disposition and neutron absorbers in control rods. Here, we report the results a preliminary comparative investigation synthesis by molten salt conventional solid-state synthesis. We show that proceeds from pyrochlore phase Ti O 7 which is first formed kinetic produ...
The growth and structure of Pt nanocrystals NCs formed by ion implantation in a-SiO2 has been investigated as a function of the annealing conditions. Transmission electron microscopy and small-angle x-ray scattering measurements demonstrate that the annealing ambient has a significant influence on NC size. Samples annealed in either Ar, O2, or forming gas 95% N2: 5% H2 at temperatures ranging f...
The experimental apparatus for time-lapse fluorescence imaging of spreading S. meliloti was described in [1]. The agar plate with the spreading S. meliloti was imaged through a 2× achromatic lens (MAP1075150-A, ThorLabs) and (for fluorescence) a GFP emission filter (MF525-39, ThorLabs) onto a cooled, 1300 × 1030 CCD array (Princeton Instruments). Images were collected at a rate of 0.001 Hz for ...
