PURPOSE Zirconia ceramics are a viable alternative to titanium for use as dental implants. However, the smooth surface of zirconia means that longer healing periods are needed to accomplish osseointegration compared to roughened titanium surfaces. Surface modifications can be used to increase the roughness of zirconia. The aim of this study was to assess histologically and compare the degree of...

Congenital swine pox infection was identified in 13 piglets with typical gross cutaneous lesions that were present at birth. Characteristic microscopic features of swine pox infection were noted in the more acute cases, whereas chronic cases presented less specific skin lesions. In the four affected herds, disease occurred as a sporadic condition with low morbidity and high case fatality rates....

Standard Dutch and German have two reflexive forms: a weak form (zich in Dutch and sich in German) and a strong form (zichzelf in Dutch and sich selbst in German). The choice between the two reflexive forms in Dutch has been explained by the selectional restrictions of the verb, distinguishing between three verb classes: inherently reflexive verbs, accidentally reflexive verbs and transitive ve...

1. The action of potassium iodide in preventing a significant rise in the blood cholesterol of rabbits fed cholesterol was temporary. After about 4 months it lost its effectiveness and the blood cholesterol rose. 2. In rabbits with hypercholesterolemia resulting from long continued cholesterol feeding, the administration of potassium iodide caused a marked rise in the blood cholesterol. 3. On t...

Dirac electron theory and QED do not take into account gravitational field, while the corresponding Kerr-Newman solution with parameters of electron has very strong stringy, topological and non-local action on the Compton distances, polarizing space-time and deforming the Coulomb field. We discuss the relation of the electron to the Kerr’s microgeon model and argue that the Kerr geometry may be...

In cholesterol-fed rabbits, alloxan-diabetes has an anti-atherogenic effect, which is associated with severe elevation of plasma triglyceride concentrations. To study this effect, we measured lipoprotein sizes and aortic permeability coefficients for cholesteryl ester and for albumin in hypertriglyceridemic diabetic cholesterol-fed rabbits and in normotriglyceridemic cholesterol-fed rabbits. Wi...

Dieser Beitrag widmet sich deshalb einerseits der Bestimmung von Fahrtlängenund Standortverteilungen empirischer Quellen und ihrer Übertragbarkeit auf die Elektromobilität. Andererseits werden darauf aufbauend die ungesteuerte Lastprofilbildung sowie die Erfüllbarkeitsanalysen des Mobilitätsverhaltens von Elektrofahrzeugen dargelegt. Zusätzlich wird eine PV-orientierte Ladestrategie vorgestellt...

ions much more so than in the past Such occurrences have notably coincided with events referred to as transitions from classical to nonclassical physics. The terminology classical‘nonclassical is here taken to refer to an attempted extension of existing classical procedures to the realm of microphysics. Such extensions were found to be subject to not earlier noted limitations. Hence a disciplin...

The prevalence of coccidia infection among domestic rabbits in Riyadh, Saudi Arabia was investigated for one year in the present study. Based on the morphological features of oocysts, ten species of Eimeria were identified in 100 fecal samples of domestic rabbits. The overall prevalence was 75%. Mixed infection with three different species occurred most frequently. The species detected and thei...

terised in this and in other countries by a striking decrease of small-pox mortality. It must be borne in mind that at the time of the introduction of vaccination a large proportion of the population was protected by previous attacks of small-pox, either natural or inoculated, and that the amount of vaccination adequate to afford a great protection in the earlier years of the century ceased to ...
