conclusions our results showed the rate of effects of different risk factors on imipenem resistance. regarding the studied risk factors, appropriate programs must be set in place to control and prevent imipenem resistance in gram-negative bacteria. results of the 374 isolated, 134 were imipenem resistant, and 240 were sensitive to imipenem. the resistance rate was more common in males and in pa...

Using  principle  of  minimum  total  potential  energy  approach  in conjunction  with  Rayleigh-Ritz  method,  the  electro-thermo- mechanical  axial  buckling  behavior  of  piezoelectric  polymeric cylindrical  shell  reinforced  with  double-walled  boron-nitride nanotube  (DWBNNT)  is  investigated. Coupling  between  electrical and mechanical  fields  are  considered  according  to  ...

The objective of this paper is to study the effect of the internal transducer resistance on the dynamic behaviour and the output power of an energy harvester when it is attached to a cubic load resistance. It is seen that by considering the internal resistance, the dynamic equation of a conventional nonlinear energy harvester changes so that it is not easy to separate the linear damping from th...

the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...

D ata on dietary intake characterized by high glycemic index and glycemic load and development of type 2 diabetes have been inconsistent. A total of four studies have shown positive associations (1–4). One study showed consistent associations for both glycemic index and glycemic load (1), while in the other three, only glycemic index was predictive of diabetes (2–4). In contrast, the Atheroscle...
