background and aims: elastomeric chains and niti coil springs are two major traction aids in orthodontic tooth movements. force degradation occurs over time in both groups, with higher percentages in elastic chains. the effects of environmental factors and some mouth rinses on this force decay have been previously studied. no study has been performed to evaluate the effect of current popular mo...

Planning a trip to a particular destination can be a time consuming and daunting task. There is a wide range of information sources available, each claiming to present the best deals and the most complete tourist information. This information as well as the current weather, budget constraints, time constraints, and personal preferences all need to be taken into account when planning the perfect...

Transforming growth factor beta receptor II interacting protein 1 (TRIP-1), a predominantly intracellular protein is localized in the ECM of bone. TRIP-1 lacks a signal peptide, therefore, in this study, we provide evidence that intracellular TRIP-1 can be packaged and exported to the ECM via exosomes. Overexpression of TRIP-1 in MC3T3-E1 cells resulted in increased matrix mineralization during...

The main goal of this study was to obtain insight about the factors that influence students' ability to learn during a field trip, in order to improve the planning and execution of learning field trips. The study was conducted in the context of a 1-day geological field trip for high school students in Israel. Three domains were tested by observations and questionnaires: (1) the nature of the le...

introduction: neural stimulation is a promising new technology for the treatment of medically-intractable seizures.  transcranial magnetic stimulation (tms) is a simple, non-invasive, low cost technique which is widely used in neurophysiology. in a few studies that have been performed at different frequencies the therapeutic effects of this technique were not obvious. repetition of low frequenc...

the purpose of the study was to identify and prioritize the educational needs and support needed by agricultural extension agents in isfahan, islamic republic of iran. the target population for the study consisted of s3 agricultural extension agents in isfahan province. census population were used therefore, sampling procedures were not utilized and genera i izability of the results was lim...

The onset and degree of injury occurring in animals that develop hyperoxic acute lung injury (HALI) is dependent on age at exposure, suggesting that developmentally regulated pathways/factors must underlie initiation of the epithelial injury and subsequent repair. Type II TGFβ receptor interacting protein-1 (TRIP-1) is a negative regulator of TGFβ signaling, which we have previously shown is a ...

The process of selection, configuration and consumption of tourist information services is a complex task for the user. This is not least since existing tools most often focus on supporting either the preor post-trip phase or the on-trip phase itself by providing context-aware services. The goal of this thesis is to establish a framework that makes pre-trip services context-aware, thus reducing...

ound-trip translation (RTT), otherwise known as reverse translation or back-and-forth translation, involves the translation of text from one language to another (the forward translation or FT) and back again (the back translation or BT), e.g., a paragraph written in English can be translated to Spanish, and then, the resulting Spanish text can be translated back to English again. RTT has been u...

In this paper we first considered a maximum likelihood estimation of trip distribution problem and next use primal-dual geometric programming method the said trip distribution problem converted into an entropy maximization trip distribution problem. Here the generalized cost function is assumed in different form, and then the said formulation is equivalent to single or multi-objective entropy m...
