The aim of the present work is to describe the semantics and the discursive functions from a general cognitivist point of view of the usage of the Present Perfect in the spoken Spanish of Chile, Paraguay and Uruguay. It is argued that cross-linguistic values that prevailing theories often ascribe to perfect, such as continuity, current relevance and recency to the speech time –ST– do not offer a c

Popular Abstract in Swedish Grupp B streptokocker (GBS; Streptococcus agalactiae) är den vanligaste orsaken till livs-hotande infektioner hos nyfödda barn. Enbart i USA orsakar GBS ~10 000 fall av meningit (hjärnhinneinflammation), pneumoni (lunginflammation) och sepsis (blodförgiftning) varje år. Infektionerna har hög dödlighet och en stor del av de barn som överlever infektionerna får bestående Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity.

A limited Round Robin test has been carried out with different types of foot models. Eight laboratories carried out the tests. The foot models varied in sizes from 254 to 275 mm, representing boot sizes from 41 to 44. Tests with both a bare foot and sock were carried out at about +20 °C and 50% RH. The boots, a thin rubber and a winter boot, were tested at about +5 °C and 85% RH. The conditioning

In this book, ten doctoral students share and discuss a number of metho- dological concerns they have faced in the process of doing research. In the first part, “Capturing the field,” the contributors grapple over issues regarding how to define and demarcate the field of research, for instance in studies on immigrant organizations, red light districts on the Internet, and telephone interviewing. I

This essay reflects on the advantages and dangers of using visual art in the teaching of history. It concludes with a number of practical suggestions to teachers who want to use art in their teaching.

The load response during and after a severe fault is critical for transient stability. This risk increases with the presence of induction motors in the load area. This paper provides analysis of the load voltage characteristic under large voltage variations. Field measurements from a noneffectively earthed system, from phase-to-phase faults at the 50 kV-level in Sweden, have been used. The time-va

This book studies the technognomies of memory in scripto as in texts, lists, dictionaries and databases and less the technognomies of memory in vivo (as in remembering). There are of course some relations between these two kinds of memories, being memory-in-scripto a development parallel to the development of written language. We notice that the historical presentation is built upon both forms of

Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are highly desirable. A Swedish company, Oroboros AB, has developed a novel clean synt
