To inform potential governmental regulations, we aimed to develop a list of electronic nicotine delivery system (ENDS) product features important to U.S. consumers by age and gender. We employed qualitative data methods. Participants were eligible if they had used an ENDS at least once. Groups were selected by age and gender (young adult group aged 18-25, n = 11; middle-age group aged 26-64, n ...

Background: Missing a tooth can lead to reduced masticatory efficiency. The solution this problem is use dental bridge. However, based on research conducted by Geiballa, it known that there are patients who dissatisfied with the function of their fixed dentures. Dissatisfaction have detrimental effect patients. So necessary evaluate patient satisfaction, which focuses function, find out more ab...

There are a number of parameters influencing the dynamic and seismic response of bridges. Of these, two important parameters warranting special notice include: the properties of the neoperenes in the state of connection between girders and columns and the shear stiffness of underlying soil in the level of bridge substructure’s connectivity to the ground. In &#10this paper, the effects of these ...

However fundamental he may appear to us, the public prosecutor was an historical latecomer. Judge and jury we can trace back to the high Middle Ages. But the prosecutor became a regular figure of Anglo-American criminal procedure only in Tudor times. Further, his appearance then has not been noticed in our historical literature, an especially remarkable omission when we discover that the prosec...

ports are the most important economic, political and military bottlenecks. this puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. correct and exact estimation of...

Among multilevel inverter topologies, asymmetric Cascaded H-Bridge (CHB) inverters have higher output-voltage levels than symmetrical ones. However, asymmetric multilevel inverters need pre-stage isolated and floating DC power sources, which make the system complicated and bulky. This paper is focused on solving the problem by using a single-core (magnetically-coupled) multiple-output forward-f...

Many empirical studies point towards an increase in non‐standard employment. The reasons for this rise are mainly seen in the increasing economic internationalization or the rapid technological changes which raise the need for both flexibility and cost‐cuts on behalf of firms. Yet, only little is known about the role of firm age in this context. Based on a large representative data set of est...

Death rates are widely used as a convenient way of summarising important aspects of health in a population. However, they are not always easy to interpret, and even when techniques such as standardisation are used the impact of premature death may be difficult to assess. Cohort analysis provides summary information that takes account of age at death and that can be displayed graphically in a re...
