INTRODUCTION Ramps, (Allium tricoccum or Allium tricoccum var. burdickii, Alliaceae) also known as wild leeks, are native to the Appalachian mountain region in eastern North America (Fig. 1). Ramps can be found growing in patches in rich, moist, deciduous forests as far north as Canada, west to Missouri and Minnesota, and south to North Carolina and Tennessee. As one of the first plants to emer...

As we age, physiological or pathological tooth wear can alter our occlusion from canine-guided (or ‘canine-protected’) lateral excursion, to group function. Group function itself is not problematic, but the burden of excursion be damaging compromised teeth. It may desirable restore patient protect heavily restored A minimally invasive option canine ramp.

Block ramps are hydraulic structures which are commonly used in river restoration projects. Especially in the last few decades, the use of this type of structures have become more and more popular. They furnish a correct balance between the hydraulic functioning and the environmental care, as they minimize the impact on the environment in which they are located. In addition, they can be conside...

In this issue of JCHIMP, Meade et al., publish the results of qualitative analysis regarding a second-year rotation in tracing the outcome of discharged patients. They report that their residents develop remarkable insights into the types of failures and miscommunications that plague our discharge processes. This perspective piece places this article in the context of literature seeking to unde...

The effects of channelization with low in-stream barriers in mountain rivers on macroinvertebrate communities are still weakly recognised. We aimed to assess the differences structure and density benthic macroinvertebrates between two north Carpathian rivers: one channelized a cascade concrete sills other block ramps. Water was collected five times for physicochemical analysis. Macroinvertebrat...

The goal of the calibration process is to use predictive models developed with data collected from other jurisdictions and apply them to the jurisdiction of interest by adapting the models for local conditions and characteristics specific to this jurisdiction. Given the large costs associated with data collection, this process is often the only method available to transportation agencies for es...

The cell transmission model of a freeway is used to compare four congestion-reducing schemes: (R) ramp control only; (T) one lane is tolled and ramps are uncontrolled; (B) bottlenecks are tolled and ramps are uncontrolled; and (RB) ramps are controlled and bottlenecks are tolled. In the base case, ramps are uncontrolled and there are no tolls. It is found that (T) is inefficient and may leave a...
