Yersinia enterocolitica is a food-borne pathogen that causes gastroenteritis with occasional postinfection sequels. This study was aimed to determinate the pathogenic potential, antimicrobial susceptibility, and genomic relationships of Y. enterocolitica strains of different bioserotypes (B/O) isolated from foods and human samples in San Luis, Argentina. Strains obtained by culture were biosero...

Native Sathiya. The operation for the removal of the defect of vision depending on cataract, as practised by this class, is somewhat similar to the, old operation of " couching"?ail operation which, till a recent date, held its own place in opposition to other modes of treatment, in the hands of the surgeons of more civilised countries. But the instruments employed by them are certainly most pr...

A new method of computing all optimal certain rules from an incomplete information system is presented and proved. The method does not require changing the size of the original incomplete system. Additionally. several existing rough set methods of computing decision rules from incomplete information systems are analyzed and compared. We show which of these methods are capable of generating ail ...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

In this chapter we propose an oligopoly mode] where firms invest in cost zeducing R&D for producing homogeneous goods that are sold in a market. In particular, we assume that R&D efforts build up a "stock of lmowledge", which, in tura, redúces margina] costs of production. Moreover, though ail firms are competitors in the marketplace, they can decide to collaborate through cooperation agreement...

Magnetoresistance of the t.ittle organic metal, where BO is bis[ethylenedioxy)tetrathiafulvalene, is investigated. The angle dependent oscillations indicate the existence of cylindrical Fermi surface, and trie observed penodicity is consistent with the calculated band structure. The amplitude of the oscillation is very small in the direction where the Fermi surface touches trie zone boundary. T...

This paper tests for the absence of expected red profits from forward market speculation. It contrasts with the literature that has considered opportunities for expected tmrnitd prolit from speculation that is. protits denominated in one of the currencies. These studies assume money illusion on the part of market participants, but this paper does not. Empirical results (ail to tind evidence of ...

-The interaction between varions fluxes and the motion of incommensurate(1) modulation is treated within a phenomenological approach. Three types of fluxes are considered : the polarization current, the conductivity current and the heat flux. It is shown that in the I phase ail currents are associated with the motion of the I modulation and thus phenomena qualitatively similar to those well kno...

A duplex PCR assay targeting the ail and 16S rRNA genes of Yersinia enterocolitica was developed to specifically identify pathogenic Y. enterocolitica from pure culture. Validation of the assay was performed with 215 clinical Yersinia strains and 40 strains of other bacterial species. Within an assay time of 4 h, this assay offers a very specific, reliable, and inexpensive alternative to the co...
