new structural, metamorphic, finite strain and kinematic vorticity data for granitic gneiss and metavolcano-sedimentary rocks of thetanumaharea in the arabian shield in saudi arabia reveal a history of deformation reflecting different tectonic regimes. kinematic analysis shows their relationship to the nappe contacts between the granitic gneiss and metavolcano-sedimentary rocks and explains the...

Many pathogen life histories include a free-living stage, often with anatomical and physiological adaptations promoting persistence outside of host tissues. More durable particles presumably require that the pathogen metabolize more resources per particle. Therefore, we hypothesize functional dependencies, pleiotropic constraints, between the rate at which free-living particles decay outside of...

Notched tensile bars of a high strength structural steel were loaded to void coalescense. The resuIts show that the damage curve determined using radially loaded specimens is not valid for specimens under nonradial loading. The results of the experiments with different load histories of notched tensile bars show, that a single parameter criterion like a damage parameter is not sufficient to des...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

Hamstring muscle strain injuries remain one of the most challenging issues facing sports medicine. 1 Over the past 100 years, there has been a gradual evolution in our understanding and management of hamstring injuries, but the challenge of optimising the management of the acutely injured hamstring remains. In recent years, increasingly high-quality studies have addressed the aetiology, risk fa...

Understanding the relationship between structure and function in the heart requires a knowledge of the connection between the local behavior of the myocardium (e.g., shortening) and the pumping action of the left ventricle. We asked the question, how do changes in preload and afterload affect the relationship between local myocardial deformation and ventricular volume? To study this, a set of s...

The Thai-53 strain of Mycobacterium leprae has been widely utilised for many experiments as a type strain in leprosy research. – 3 However, the origin and history of the strain is not clearly understood by most researchers. This letter describes the history and some genomic characteristics of the Thai-53 strain. The bacilli were obtained from a biopsy sample of an LL patient in Thailand on 25th...

Creep strain experiments on uncemented reservoir sands suggest that the time-dependent component of deformation can be modeled using linear viscoelasticity theory. The standard approach to solving for the values of the appropriate model parameters is to fit creep strain data as a function of time. However, by writing the creep compliance function in terms of strain-rate rather than strain, it i...
