Instrument fracture is a procedural mishap that prevents efficient cleaning and shaping of the root canal. When bypassing the fracture fails, the fragment must be removed. Many techniques and devices ...have been described to remove fragments from the root canal. The Masserann Kit is a widely used instrument for the removal of fragments. These clinical cases describe use of the Masserann Kit to remove separated instruments blocking the entire canal in posterior teeth.
In the year 2015 Europe was facing what appeared to be the worst migration crisis since World War II. Its coverage in Lithuanian media has spurred different voices to reach out for the audience: the ...country was facing the New Other, with whom there were no shared memories or experiences. Certain historic narratives and their motifs were invoked into discussion in order to embrace certain attitudes or actions while trying to comprehend the ongoing crisis: The Grand Duchy of Lithuania, World War II and Soviet Occupation. The two-staged research was done in order to reveal how historical narratives were used to comprehend the possible newcomers and project outcomes of positioning migrants. 7 major news portals were used as a source of research, chosen by its importance or audience reach on national and regional levels
with key words “pabėgėlis” (refugee), “migrantas” (migrant), “nelegalas” (illegal person), “bėglys” (fugitive), “atbėgėlis” (arrival). At the first stage, trending discourses and keywords were revealed, while during the 2nd the usage of historical narratives while positioning the newcomers was analysed.
Researchers have independently documented the effects of land use on rivers and threats to river management institutions, but the relationship between changes in institutional context and river ...condition is not well described. This study assesses the connections between resource management institutions, land use, and rivers by integrating social science, geospatial analysis, and geomorphology. In particular, we measured hydraulic geometry, sediment size distributions, and estimated sediment yield for four rivers in northern Tanzania and conducted semistructured interviews that assessed corresponding resource management institutions. Communities managed rivers through both customary (traditional, nonstate) and government institutions, but the differences in the resource management policies and practices of the study rivers themselves were fairly subtle. Clearer differences were found at broader scales; the four watersheds exhibited substantial differences in land-cover change and sediment yield associated with the location of settlements, roadways, and cultivation. Unexpectedly, these recent land-use changes did not initiate a geomorphic response in rivers. The long history of grazing by domestic and wild ungulates may have influenced water and sediment supplies such that river channel dimensions are more resistant to changes in land use than other systems or have already adjusted to predominant changes in boundary conditions. This would suggest that not all rivers will have the anticipated responses to contemporary land-use changes because of antecedent land-use patterns; over long time scales (centuries to millennia), the presence of grazers may actually increase the ability of rivers to withstand changes in land use. Our findings point to a need for further interdisciplinary study of dryland rivers and their shifts between system states, especially in areas with a long history of grazing, relatively recent changes in land use, and a dynamic social and institutional context.
In this paper we analyse the optimal management of a renewable resource (groundwater) with stock‐dependent extraction cost and a backstop substitute, facing two‐sector linear demands. Application to ...the Kiti region in Cyprus demonstrates the model's performance and is used to test for the difference between optimal and myopic behaviour. It is found that the presence of a backstop resource diminishes the importance of optimal dynamic behaviour, whereas in the absence of backstop the optimal control solution yields a value for social welfare significantly larger than the myopic policy.
