Techniques for Rehabilitating Pavements Without Overlays - A Systems Analysis Vol. 2 Appendixes
DOT-FH-11-9142The objective of the study was to determine the feasibility of a variety of innovative techniques for rehabilitating pavements without using thick overlays and to develop these techniques to the point where they could be implemented. A total of 39 potential techniques were identified. To determine their feasibility a systems decision analysis computer program was developed which utilizes utility theory to simultaneously consider 17 different decision criteria under four main attributes (Cost, Performance, Energy and Impact). Using this utility decision analysis program, a total of 19 techniques demonstrated the capability of solving certain problems better than currently used techniques. Included in the 19 promising techniques are a) use of rejuvenating agents for flexible pavements, b) horizontally-bored sleeper slab and joint restoration for rigid pavements, c) precast joint assemblies for rigid pavements. d) change the location of lane markings, and e) reworked surface of flexible pavement. For other specific problems the program indicated presently used techniques are better than any of the potential techniques. And finally. the program I revealed that 15 potential techniques did not show any promise at this time. Suggestions for further development, implementation and research have been made
The superconducting ferromagnet UCoGe
The correlated metal UCoGe is a weak itinerant ferromagnet with a Curie
temperature T_C = 3 K and a superconductor with a transition temperature T_s =
0.6 K. We review its basic thermal, magnetic - on the macro and microscopic
scale - and transport properties, as well as the response to high pressure. The
data unambiguously show that superconductivity and ferromagnetism coexist below
T_s = 0.6 K and are carried by the same 5f electrons. We present evidence that
UCoGe is a p-wave superconductor and argue that superconductivity is mediated
by critical ferromagnetic spin fluctuations.Comment: 19 pages; review paper; accepted for publication in the Journal of

Quality indicators for patients with traumatic brain injury in European intensive care units
Background: The aim of this study is to validate a previously published consensus-based quality indicator set for the management of patients with traumatic brain injury (TBI) at intensive care units (ICUs) in Europe and to study its potential for quality measur

Evidencias produzidas por pesquisas qualitativas sobre diabetes tipo 2: revisao da literatura
Type 2 diabetes has a major impact on patients lives and the healthcare network. Given the growth in qualitative information on diabetes, it becomes important to systematize this knowledge. A meta-study on diabetes was conducted through analysis on 42 articles that were made in journals at the periodicals portal of the Coordination Office for Advancement of Higher-level Personnel (Capes). We found that the studies reviewed had a good theoretical basis, which included: care management, health-disease concepts, professional-patient relationships, professional practices and treatment compliance. The articles clearly described the methodological procedures used. The use of interviews and focal groups for data gathering predominated, and it was sought to explore different views of the individuals investigated. It was reaffirmed that it was important for health professionals and managers to implement healthcare policies, programs and models that are appropriate for the specific features of chronic illness, guided by comprehensive care and co-responsibility
