1. Immediate and delayed photoactivation of self-adhesive resin cements and retention of glass-fiber posts
The aim of this study was to evaluate the effect of immediate and delayed photoactivation of self-adhesive resin cements (SARCs) on the retention of glass-fiber posts luted into root canals. Bovine incisors were endodontically treated, and post holes of 9 mm in depth were prepared. Fiber posts were luted using one of two SARCs, BisCem(r) (Bisco Inc., Schaumb

2. Modelo gravimétrico en el borde noreste del macizo norpatagónico
We present a gravimetric study on the northeast edge of the North Patagonian massif in the province of Rio Negro, to ascertain the depth distribution of the different outcrop units in the study area, as well as the geometry of the Navarrete Plutonic Complex. The negative anomalies in the Bouguer residual map reproduce the lateral density contrast between wha

3. Influence of storage times on bond strength of resin cements to root canal
The resin cements are responsible to retention of the indirect materials decreasing marginal leakage, increasing failure resistance compared with conventional cementation. The cementation within root canal is very hard due unfavorable conditions regarding the application of adhesive techniques caused by inadequate access. Therefore, considering the possibili

4. RESISTÊNCIA DE UNIÃO DE SISTEMAS ADESIVOS ATUAIS EM DENTINA SUBMETIDA A DIFERENTES TRATAMENTOS / BOND STRENGTH OF ADHESIVE SYSTEMS IN DENTIN SUBMITTED TO DIFFERENT TREATMENTS
Estudos têm demonstrado que a longevidade de restaurações adesivas é negativamente afetada pela degradação das fibras colágenas. O objetivo deste estudo foi avaliar o efeito de diferentes tratamentos na resistência de união de sistemas adesivos em diferentes regiões dentinárias. Quarenta dentes terceiros molares humanos hígidos foram alocados ran

5. Efeito da irradiação do laser diodo 980 nm na microdureza da dentina radicular tratada previamente com diferentes soluções irrigantes / Effect of irradiation with diode laser (980 nm) on microhardness of root dentin previously treated with different irrigating solutions
The purpose of the present study was to evaluate, in vitro, the effect of 980 nm diode laser irradiation, in potencies of 1.5 and 3.0 W and 100 Hz frequency, on microhardness of radicular dentine in different depths. Seventy two roots of human canines were instrumented and randomly distributed into 3 groups (n=24), according to the irrigating solution used i

6. Análise in vitro do efeito inibitório de restaurações contendo o monômero antibacteriano MDPB na progressão de cáries secundárias em raizes dentárias / in vitro analysis of inhibitory effects of the antibacterial monomer MDPBcontaining restorations on the formation of secondary root caries
This in vitro study aimed to analyze the potential of restorative materials containing the antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB) for controlling the advance of bacterial induced secondary root caries-like lesions. Class V cavities (2 mm x2 mm) were prepared in seventy-five human root fragments. Specimens were randomly divid

7. Adhesive cementation of zirconia posts to root dentin: evaluation of the mechanical cycling effect
This study evaluated the effect of mechanical cycling on the bond strength of zirconia posts to root dentin. Thirty single-rooted human teeth were transversally sectioned to a length of 16 mm. The canal preparation was performed with zirconia post system drills (CosmoPost, Ivoclar) to a depth of 12 mm. For post cementation, the canals were treated with total

Caracterização geofísica de alvos rasos com aplicações no planejamento urbano e meio ambiente: estudo sobre o sítio controlado do IAG/USP / Geophysics characterization of shallow targets with applications in the urban planning and environmental: Study on the Shallow Geophysical Test Site of IAG/USP.
The implantation of the Shallow Geophysical Test Site (SCGR) of the Astronomy, Geophysics and Atmospheric Sciences Institute (IAG), from University of Sao Paulo (USP), is a mark in national geophysical history. It is the first site Shallow geophysical study site installed in Brazil. This Test Site is located next to Physics Institute in front of IAG/USP, com

9. O sítio controlado de geofísica rasa do IAG/USP: instalação e resultados GPR 2D-3D
A interpretação de dados de investigações geofísicas rasas pode ser complexa devido às incertezas a respeito dos alvos em subsuperfície. Para reduzir as ambigüidades e auxiliar a interpretação dos dados geofísicos de superfície foi instalado no campus da USP o Sítio Controlado de Geofísica Rasa do IAG-USP. Diferentes alvos foram instalados em v

10. Maturação do queijo tipo prato : influencia da adição de enzimas proteoliticas no processo
The ripening process of cheese is a very complex process that involves the development in many different ways of a great variety of flavor compounds that affect the aroma and taste of the finished product. Throughout the ripening process, the protein content undergoes a considerable number of changes that influence its physical and structural properties. The

11. Spatial Changes in the Bacterial Community Structure along a Vertical Oxygen Gradient in Flooded Paddy Soil Cores
Molecular ecology techniques were applied to assess changes in the bacterial community structure along a vertical oxygen gradient in flooded paddy soil cores. Microsensor measurements showed that oxygen was depleted from 140 μM at the floodwater/soil interface to nondetectable amounts at a depth of approximately 2.0 mm and below. Bacterial 16S rRNA gene (rD

12. Quantitative studies of human cardiac metabolism by 31P rotating-frame NMR.
We have developed 31P NMR spectroscopic methods to determine quantitatively relative levels of phosphorous-containing metabolites in the human myocardium. We have used localization techniques based on the rotating-frame imaging experiment and carried out with a double-surface coil probe. Information is obtained from selected slices by rotating-frame depth se
