Softening frequently occurs in dual-phase steels under isothermal tempering of martensite. Recently, non-isothermal tempering is implemented to decrease the softening process in dualphase steels. Here, we have discovered using high power electropulsing treatment can significantly enhance the strengthening effects via the formation of ultrafine-grained ferrite with nano-cementite particles in te...
where E(x, y) > 0. The parametric curves x = const. and y = const. form an isothermal net on 1. It is well known that h(x, y) = c, where h is a harmonic function of (x, y), that is, h satisfies the Laplace equation, hA, + h,, = 0, defines an isothermal family of curves on Z. The constant c is called the isothermal parameter. The converse of the preceding statement is not valid. That is, if g(x,...
Techniques of isothermal microcalorimetry have been much improved during the past two decades. In addition to their use in fundamental research, applications of practical importance have been established in some areas. However, no significant use of isothermal microcalorimetry has yet been seen in practical applications of biology, despite many methodological studies reported from that area. Th...
the effects of temperature, time and the strategy of prepolymerization were studied on the morphology of polypropylene particles. propylene polymerization was carried out in slurry phase using 4th generation of ziegler-natta catalyst, cyclohexylmethyl dimethoxysilane as external electron donor, and triethyl aluminum as co-catalyst. prepolymerizations were carried out based on two strategies: is...
بندپایان در حدود 75درصد انواع جانوران از جمله کنه های ایکسودیده ، بزرگترین شاخه جانوری می باشند (یخچالی و حاجی حسن زاده زرزای, 1383). خانواده کنه های سخت در زیر راسته متااستیگماتا و راسته کنه سانان (آکارینا) از شاخه بندپایان قرار دارند (wall and shearer, 2001). تاکنون 650 گونه و در حدود 13 جنس در 5 زیرخانواده از آنها گزارش گردیده است (wall and shearer, 1997; wall and shearer, 2001 ). به طوری که...
سابقه و هدف: فاسیولا هپاتیکا و فاسیولا ژیگانتیکا فلوک های کبدی شایعی بوده که روی انسان ها و دام ها در تمام نقاط جهان اثرگذار هستند. در مطالعه حاضر ما تکنیک سریع loop-mediated isothermal amplification (lamp) را در تشخیص و افتراق گونه های فاسیولا ارزیابی نمودیم. مواد و روش ها: تعداد 50 کرم فاسیولا از کبد گاو و گوسفند کشتارگاه های استان مازندران جداسازی شدند. تعداد 8 پرایمر جهت تکثیر ناحیه ژنی 28s ...
conclusions the analytical sensitivity of lamp and pcr methods, using the designed primers, was 8 times more than any other reported methods. the designed methods are specific and sensitive for detection of h. pylori in different clinical and environmental samples. results the detection limits of the lamp and pcr assay were similar and were 10 fg of pure dna of h. pylori, which is equal to 6 co...
