In this article di$erences between rational, policy-based, and rationalized voting are discussed, and it is argued that these forms of electoral decision making are not properly analyzed in existing electoral studies. Policy voting, persuasion, and projection are then redefined as three possible ways of restoring balance among imbalanced triads of political beliefs and attitudes. With the help ...

objective: evaluating the effect of resin coating and chlorhexidine on microleakage of two resin cements after water storage. materials and methods: standardized class v cavities were prepared on facial and lingual surfaces of one hundred twenty intact human molars with gingival margins placed 1 mm below the cemento-enamel junction. indirect composite inlays were fabricated and the specimens we...

BACKGROUND AND AIMS Most species of Dalechampia vines (Euphorbiaceae) attract bee pollinators with terpenoid resins secreted by a gland-like structure in the inflorescence. In some species, pollinating bees appear to preferentially visit inflorescences (blossoms) with large resin-producing glands, whereas in other species bees preferentially visit blossoms with large involucral bracts. In this ...

To determine some physiological and biochemical changes in Capsicum annuum L. grown in vitro, the effects of different Cu concentrations on this plant were investigated. Cu was applied in the form of Cu sulfate (CuSO4) in three levels (0, 0.1, and 0.2 mM) and at three times (days 8, 10, and 12). With Cu treatments, superoxide dismutase (SOD), catalase (CAT) activities, and total phenolic compou...

It is known that the metabolism of plants is divided in primary and secondary. The substan‐ ces that are common to living things and essential to cells maintenance (lipids, proteins, car‐ bohydrates, and nucleic acids) are originated from the primary metabolism. On the other hand, substances originated from several biosynthetic pathways and that are restricted to determined groups of organisms ...

In this study, the stress distribution in the shrinkage process when a light-cured composite resin is irradiated with light was estimated. We assumed that shrinkage and hardening of the light-cured composite resin resulted from light irradiation and was the same as that caused thermally. On the basis of this assumption, we simulated the deformation during the shrinkage of the composite resin us...

introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...

Elicitors are compounds, which activate chemical defences in plants. Various biosynthetic pathways are activated in treated plants depending on the compound used. The most intensively studied elicitor for manipulating defence pathways in plants is methyl jasmonate, which modifies e.g. the production of terpenoids, the main constituents of conifer oleoresin. Other commonly tested chemical elicit...

Resin Composites Sandwich restorations and Curing techniques Anders Lindberg, Department of Dental Hygienist Education, Faculty of Medicine, Umeå University, 901 87 Umeå, Sweden. Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing dema...

Resin coating technique is a unique method that improves the dentin bond strength of resin cements in indirect restorations. However, the weak link of a specimen bonded using the resin coating technique was reported to be the bonded interface between the resin coating material and resin cement. The purpose of this study, therefore, was to enhance the bonding performance between a resin coating ...
