to determine the prevalence of bacterial mastitis in cattle, milk samples positive for california mastitistest (cmt) were cultured during a period of almost 4 years. the bacterial species isolated from 2904 milksamples studied were coagulase negative staphylococcus sp. in 879 (30.27%) samples, streptococcusagalactiae in 642 (22.11%), s. dysgalactiae in 332 (11.43%), e. coli in 295 (10.16%), sta...

With the increasing innovation of new electronic devices continually entering the marketplace, manufacturers and retailers are seeking partnerships with third party logistics (3PL) providers that can decrease e-waste through reverse logistics for end-of-life devices. With the general public’s sentiment to preserve the environment for future generations, manufacturers and retailers as well as th...

The aim of this paper is to construct an e¢ cient iterative method to solve nonlinear equations. This method is obtained from M. Javidi’s method (Appl. Math. Comput. 193 (2007) 360-365), which is third-order. The convergence order of new method is established to six and the e¢ ciency index is 1.5651. The Proposed method is compared with the second, third and sixth order methods. Some numerical ...

We describe several techniques for the calculation of multi-loop integrals and their application to heavy quark current correlators. As new results, we present the fourloop correction to the second and third physical moment in the low-energy expansions of vector, axial-vector and scalar quark current correlators. Using a Ward identity, we obtain the third and fourth moment for the pseudo-scalar...

We report on the case of a frustrated 90-year-old gentleman who was seen in the Accident and Emergency department for the third time in four days with failure of his long-term urethral catheter. He reported that the catheter simply "fell out" with the balloon deflated. On each occasion previously, the catheter had been reinserted in A&E and the patient discharged home. These repeated visits to ...

statement of problem: microorganisms are essential for the development of periradicular diseases and are one of the major causative factors associated with endodontic treatment failures. different instruments and preparation techniques have been developed in endodontics to eliminate or reduce intracanal bacteria. purpose: the aim of this study was to compare the amount of remaining e. faecalis ...

This paper presents an off-line divisible e-cash scheme where a user can withdraw a divisible coin of monetary value 2 that he can parceled and spend anonymously and unlinkably. We present the construction of a security tag that allows to protect the anonymity of honest users and to revoke anonymity only in case of cheat for protocols based on a binary tree structure without using a trusted thi...
