Modern diagnostic methods enable clinicians to look beyond a diagnosis of chronic Q fever and discern whether patients instead have persistent focalized Coxiella burnetii infection(s). Use of these methods and development of criteria to define and treat such infections, especially cardiovascular infections, will improve the prognosis for patients previously thought to have chronic Q fever.

Given that the core issues of attention research have been recognized for millenia, we do not know as much about attention as we should. I argue that the reasons for this failure are (1) we create spurious dichotomies, (2) we reify attention, treating it as a cause, when it is an effect, and (3) we equate a collection of facts with a theory. In order to correct these errors, we need a new techn...

Is the Introspection Thesis true? It certainly isn’t obvious. Introspection is the faculty by which each of us has access to his or her own mental states. Even if we were to suppose that mental states are identical to brain states, it doesn’t follow immediately from this supposition that we can introspect our mental states as brain states. This point is analogous to the following. It doesn’t fo...

A new set-up was constructed for capillary isoelectric focusing (CIEF) involving a sampling capillary as a bypass fixed to the separation capillary. Sample solutions were subjected to a previously established pH gradient from the sample capillary. Besides performing conventional CIEF, the separation of ampholytic compounds with isoelectric points (p/s) beyond the pH gradient was carried out on ...

conomists love to say that there is no such thing as a free lunch. But the Chilean government agency responsible for school grants, Junta Nacional de Auxilio Escolar y Becas (JUNAEB), is an exception to the rule. During the school year, JUNAEB provides breakfast and lunch for 2 million children in primary and secondary public schools. In a developing country where about 14 percent of children u...

The applicability of Origanum majorana-Capped Silver nanoparticles synthesis for removing Ni (II) ions from aqueous solutions has been reported. This novel material was characterized by different techniques such as FT-IR, XRD and SEM. The influence of nanoparticle dosage, pH of the sample solution, individual ions concentration, temperature, contact time between the sample and the adsorbent wer...

urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. in this study, solid phase extraction was appropriately conditioned with regard to sample ph, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. octadecyl silica cartridge (c18) was used as ...
