Possible Resolution (possible + resolution)
Selected AbstractsMagnetic resonance microscopy of the equine hoof wall: a study of resolution and potentialEQUINE VETERINARY JOURNAL, Issue 5 2006M. D. KELLER Summary Reasons for performing study: Obtaining magnetic resonance images of the inner hoof wall tissue at the microscopic level would enable early accurate diagnosis of laminitis and therefore more effective therapy. Objectives: To optimise magnetic resonance imaging (MRI) parameters in order to obtain the highest possible resolution of the structures beneath the equine hoof wall. Methods: Magnetic resonance microscopy (MRM) was performed in front feet from 6 cadaver horses using T2 -weighted fast spin echo (FSE-T2), and T1 -weighted gradient echo (GRE-T1) sequences. Results: In T2 weighted FSE images most of the stratum medium showed no signal, however the coronary, terminal and sole papillae were visible. The stratum lamellatum was clearly visible and primary epidermal lamellae could be differentiated from dermal lamellae. Conclusion: Most structures beneath the hoof wall were differentiated. Conventional scanners for diagnostic MRI in horses are low or high field. However this study used ultra-high field scanners currently not available for clinical use. Signal-to-noise ratio (S/N) increases as a function of field strength. An increase of spatial resolution of the image results in a decreased S/N. S/N can also be improved with better coils and the resolution of high field MRI scanners will increase as technology develops and surface array coils become more readily available. Potential relevance: Although MR images with microscopic resolution were obtained ex vivo, this study demonstrates the potential for detection of lamellar pathology as it occurs. Early recognition of the development of laminitis to instigate effective therapy at an earlier stage and may improve the outcome for laminitic horses. Clinical MR is now readily available at 3 T, while 4 T, 7 T and 9 T systems are being used for human whole body applications. [source] A Rogue is a Rogue is a Rogue: US Foreign Policy and the Korean Nuclear CrisisINTERNATIONAL AFFAIRS, Issue 4 2003Roland Bleiker Two nuclear crises recently haunted the Korean peninsula, one in 1993/4, the other in 2002/3. In each case the events were strikingly similar: North Korea made public its ambition to acquire nuclear weapons and withdrew from the Nonproliferation Treaty. Then the situation rapidly deteriorated until the peninsular was literally on the verge of war. The dangers of North Korea's actions, often interpreted as nuclear brinkmanship, are evident and much discussed, but not so the underlying patterns that have shaped the conflict in the first place. This article sheds light on some of them. It examines the role of the United States in the crisis, arguing that Washington's inability to see North Korea as anything but a threatening ,rogue state' seriously hinders both an adequate understanding and possible resolution of the conflict. Particularly significant is the current policy of pre-emptive strikes against rogue states, for it reinforces half a century of American nuclear threats towards North Korea. The problematic role of these threats has been largely obscured, not least because the highly technical discourse of security analysis has managed to present the strategic situation on the peninsula in a manner that attributes responsibility for the crisis solely to North Korea's actions, even if the situation is in reality far more complex and interactive. [source] Genetic Analyses of Meiotic Recombination in ArabidopsisJOURNAL OF INTEGRATIVE PLANT BIOLOGY, Issue 8 2007Asela J. Wijeratne Abstract Meiosis is essential for sexual reproduction and recombination is a critical step required for normal meiosis. Understanding the underlying molecular mechanisms that regulate recombination is important for medical, agricultural and ecological reasons. Readily available molecular and cytological tools make Arabidopsis an excellent system to study meiosis. Here we review recent developments in molecular genetic analyses on meiotic recombination. These include studies on plant homologs of yeast and animal genes, as well as novel genes that were first identified in plants. The characterizations of these genes have demonstrated essential functions from the initiation of recombination by double-strand breaks to repair of such breaks, from the formation of double-Holliday junctions to possible resolution of these junctions, both of which are critical for crossover formation. The recent advances have ushered a new era in plant meiosis, in which the combination of genetics, genomics, and molecular cytology can uncover important gene functions. [source] High-resolution NMR correlation experiments in a single measurement (HR-PANACEA)MAGNETIC RESONANCE IN CHEMISTRY, Issue 5 2010riks Kup Abstract Three important NMR pulse sequences, INADEQUATE, HSQC and three-dimensional HMBC have been combined into a single entity called high-resolution Parallel Acquisition NMR: an All-in-one Combination of Experimental Applications (HR-PANACEA) to provide reliable structural information about a small molecule in a single measurement. This exploits a recent instrumental development that permits simultaneous acquisition of signals from several nuclear species, using multiple receivers. Where high-precision values of the long-range heteronuclear splittings are important, selected regions of a large experimental data matrix are extracted and examined with the highest possible resolution. The J -doubling technique is then applied to derive precise values for these couplings. As proof of principle, the method is applied to the molecule of methyl salicylate, confirming the expected conformation of the COH moiety. Copyright © 2010 John Wiley & Sons, Ltd. [source] Communication with the Environment?POLITICS, Issue 3 2000Non-human Nature in the Theories of Jürgen Habermas The theories of Jürgen Habermas provide us with a powerful analytical tool for the analysis of politics, including social movements. However, they are lacking in one particular area, the analysis of environmental politics. The reasons behind these difficulties can be traced through the development of Habermas's work and lie in the inability of non-human nature to participate in language-based discourse. The dilemma is acute , the ecocentric moral position needs grounding in the rationality of discourse if it is not to slip into possibly dangerous irrationality, but how can such a grounding occur? This article reviews the development of discussion in this area and investigates advocacy as a possible resolution of the problem. [source] P1 Shake-and-Bake: can success be guaranteed?ACTA CRYSTALLOGRAPHICA SECTION D, Issue 2 2000Hongliang Xu The multi-trial direct-methods procedure known as Shake-and-Bake has been applied to three small proteins (alpha-1 peptide, vancomycin and lysozyme) that crystallize in space group P1. Phase refinement was accomplished through parameter-shift optimization using both the cosine and exponential forms of the minimal function. By extending error-free data to sufficiently high resolution, 100% convergence of trial structures to solution could be achieved in all three cases by using the exponential minimal function and a shift angle in the range 130,150°. These results suggest optimum parameters for other P1 structures and emphasize the importance of collecting data to the highest possible resolution. [source] PARENTING COORDINATION: IMPLEMENTATION ISSUES1FAMILY COURT REVIEW, Issue 4 20032003 AFCC Task Force on Parenting Coordination, April 30 ABSTRACT The parenting coordinator model ("PC model") has been implemented in many states as an intervention for dealing with high conflict families in domestic relations proceedings before the courts. The PC model has been repeatedly recommended by professionals as an intervention to help families structure, implement, and monitor viable parenting plans and to reduce relitigation rates where high conflict threatens the family adjustment process. This article summarizes current professional literature on the PC model and discusses the PC model as it has been implemented in various states, outlining the implementation issues encountered. This information may serve as a guide for determining the feasibility of establishing the PC model in other jurisdictions, and provides insight into potential impediments and possible resolutions. [source] Membranes, strings and integrabilityFORTSCHRITTE DER PHYSIK/PROGRESS OF PHYSICS, Issue 5-7 2009C. Krishnan Abstract In the first half of this note, after briefly motivating and reviewing membrane field theories, we discuss their BPS funnel solutions. We discuss some aspects of embedding M-theory fuzzy funnels in these theories. In the second half, we focus on ABJM theory and discuss a test of AdS4/CFT3 based on integrability. We discuss a numerical mismatch at one loop in worldsheet perturbation theory and its possible resolutions. [source] The Multivariate Analysis Biplot as tool for conflict analysis in MCDAJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 5 2001Fabio B. Losa Abstract In this paper, the use of multivariate statistical analysis techniques to aid in conflict analysis in a multi-actor group is demonstrated. In particular, the covariance biplot technique is focused on and the resulting graphical output, called the conflict diagram, is interpreted in terms of relationships between actors, profiles of alternatives under consideration, and the interactions between actors and alternatives in terms of the conflict and its possible resolutions (consensus, coalition, etc.). The conflict analysis is divided into two distinct phases. The descriptive phase is used to represent the conflict. The prescriptive phase is used in two ways: (i) to visualize the effects of changes in parameters (,conflict resolution aid'), hopefully bringing the actors closer together, and (ii) as a tool to enhance the creative search for new alternatives (,alternative generation'). The conflict analysis process is illustrated by examining ex post a practical case study in water resource management. Copyright © 2002 John Wiley & Sons, Ltd. [source] | |||||||||||||
