Though governments at all levels -- city, county, state, and federal -- are responsible for a good portion of the infrastructure failures, the blame must be equally shared by private enterprise.
Representative volume elements of damageable and undamageable material layers are used to extract the porous portion of the deformation in the failure process zone, which is reduced to a cohesive law based on continuum damage mechanics.
For assessing the efficacy of the regimen in term of overall survival in the phase II portion of the study, the overall failure rate was estimated and compared with the failure rate of 0.6 per person-year of follow-up found in a phase III trial performed in the same patient population treated with RT plus concomitant and adjuvant TMZ.
The model prediction was found to be in very good agreement with the experimental results in terms of the global stress-strain curves, including the linear and nonlinear portion of the response and also the failure point, making it a useful virtual testing tool for composite material design.
Hispanics compose a significant portion of the nation's workforce; failure to remedy our current health care system ensures a precarious, uncertain future for our country.
A decrease in contractility is undoubtedly a major contributing factor in the pathophysiology of a significant portion of the patients with heart failure.
For example, there may be a penalty of a certain portion of the security deposit for failure to pay rent, give proper notice or fill out the full term of the lease.
It has been reported that a certain portion of the contractile deficit in heart failure is due to an impairment of Ca2+ homeostasis [ 3, 4].
Heart failure with preserved ejection fraction (HFpEF) comprises a large portion of heart failure patients and portends poor prognosis with similar outcome to heart failure with reduced ejection fraction (HFrEF).
Importantly, TNF has also a prognostic impact: TNF was elevated in a large portion of heart failure patients with preserved and reduced ejection fraction and was associated with a large decrease in survival.
