PURPOSE For evaluating the immunogenicity of an influenza vaccine, the microneutralization (MN) test has a higher sensitivity and specificity as compared to the hemagglutination inhibition (HI) test. However, the MN test is more time consuming and is difficult to standardize. We performed the MN test to determine its usefulness as an alternative or complementary test to the HI test for evaluati...
Ahstract--Mn-substituted iron oxides were synthesized by coprecipitating Fe(NO3)3 and Mn(SO4) solutions with NH4OH, adjusting the suspensions to pH 4 or 6, and then keeping the suspensions at 55~ for 62 days. The Mn mole fraction of the final products ranged from 0 to 0.3. X-ray powder diffraction patterns showed that goethite and hematite formed in each Fe-containing system. Groutite formed in...
The synthesis, structural characterization, and magnetic property studies of SrLaMnSbO6 double perovskite oxide are reported. The crystal structure of SrLaMnSbO6 has been solved by powder X-ray (PXD) and neutron diffraction (NPD) data in the monoclinic space group P21/n (a ) 5.6878(3) Å, b ) 5.6990(2) Å, c ) 8.0499(4) Å and ) 89.98(2)°; 295 K, NPD data). The Mn and Sb atoms are nearly completel...
In a previous paper, it was shown that HE is a binary form with complex coefficients having degree n > 3 and discriminant Df ^ 0, and if Af is the area of the region \F(x, y)\ < 1 in the real affine plane, then \DF\llni-"-^AF < 1B{\, \), where B{\ , 1) denotes the Beta function with arguments of 1/3 . This inequality was derived by demonstrating that the sequence {M„} defined by Mn = max|Df \Ui...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
سرطان معده (gc) از متداولترین سرطانها و دومین سرطان منجر به مرگ و میر انسانها در اثر سرطان در جهان است. mir-372 عملکردی شبه انکومیری دارد و از طریق ژن هدفش lats2 در انواع سرطانها باعث تهاجم و نیز عدم تنظیم چرخه سلولی، آپوپتوز و تکثیر سلولی می گردد. cd44 در سرطان معده مارکر سطح سلولی بنیادی سرطانی است و باعث تهاجم و متاستاز می گردد. در این مطالعه، بیان mir-372 با ترانسداکشن لنتی ویروس حامل آن در...
باکتری های paenibacillus alvei arn63 و bacillus mycoides به عنوان باکتری هایی توانا در تولید بیودی امولسیفایر، خاصیت امولسیون زدایی قابل توجهی را از خود نشان دادند. بیودی امولسیفایر تولیدی که از نوع lipopeptide می باشد، می تواند در صنعت نفت به عنوان ماده ای سازگار با محیط زیست، مورد استفاده قرارگیرد. به منظور افزایش تولید بیودی امولسیفایر، به عنوان نوعی بیوسورفکتانت، بهینه سازی شرایط محیط کشت ص...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
An unusually Mn-rich ilvaite sample from the Perda Niedda mine in Sardinia, Italy, was studied in order to clarify the Mn distribution among the different structural sites, and to observe the structural response of the mineral upon thermally induced oxidation-dehydrogenation. The crystal structure and the chemical composition of one crystal [a = 13.014(5), b = 8.867(3), c = 5.838(4) Å, b = 90.0...
