BACKGROUND Preperitoneal pelvic packing/external fixation (PPP/EF) for controlling life-threatening hemorrhage from pelvic fractures is used widely in Europe but has not been adopted in North America. We hypothesized that PPP/EF arrests hemorrhage rapidly, facilitates emergent operative procedures, and ensures efficient use of angioembolization (AE). STUDY DESIGN In 2004 we initiated a PPP/EF...

The combination of myocardial perfusion and poststress ejection fraction (EF) provides incremental prognostic information. This study assessed predictors of nonfatal myocardial infarction (MI) versus cardiac death (CD) by gated myocardial SPECT and examined the value of integrating the amount of ischemia and poststress EF data in risk stratification. Methods: We identified 2,686 patients who un...

substantial portion of patients with symptomatic heart failure (HF) have been reported to have relatively normal or preserved left ventricular (LV) ejection fraction (EF).1 ‘HF with preserved EF’ has been defined as the presence of typical HF symptoms and signs of an EF of more than 40 or 50%. Previous studies, including our own, showed that HF patients with preserved EF are older, more often f...

Background We tested the hypotheses that 1) ejection fraction (EF) assessed by cardiovascular magnetic resonance (CMR) is a stronger predictor of all cause mortality than EF assessed by echocardiography; and 2) CMR with late gadolinium enhancement (LGE) improves risk stratification over echocardiography EF in Cox regression models as determined by net reclassification improvement (NRI). Echocar...

This paper describes the questions on the consequences of the assumptions about resource sustainability and economic growth and whether sustainability and economic growth foreclose each other. Specifically, it examines four questions by: (1) Identifying the main factors in earth resource consumption in the past 40 years; (2) Finding relationships among person’s nutrition demands, food Ecologica...

One gene coding for yeast cytoplasmic elongation factor 1 alpha (EF-1 alpha) was isolated by colony hybridization using a cDNA probe prepared from purified EF-1 alpha mRNA. A recombinant plasmid, pLB1, with a 6-kilobase yeast DNA insert, was found by hybrid selection and translation experiments to carry the entire gene. The nucleotide sequence of the gene with its 5'- and 3'-flanking regions wa...

The removal of cadmium and turbidity from contaminated soil-washing water was studied by Electroflotation (EF) at the laboratory scale by using sodium lauryl sulfate (SLS) as an anionic surfactant, and calcium hydroxide (Ca(OH)2) as a coagulant. The stoichiometric cadmium to collector (SLS) and coagulant (Ca(OH)2) ratio was 1:4.5. Significant removal of cadmium (100 %, not detected in the resid...

Let f : V (G) → {1, 2,..., |V (G)|} be a bijection, and let us denote S = f(u) + f(v) D |f(u) − f(v)| for every edge uv in E(G). f' the induced labeling, by vertex labeling f, defined as E(G) {0, 1} such that any E(G), (uv)=1 if gcd(S, D)=1, (uv)=0 otherwise. ef' (0) (1) number of edges labeled with 0 1 respectively. is SD-prime cordial |ef' (1)| ≤ G graph it admits labeling. In this paper, we ...

We employ a basic formalism from convex analysis to show a simple relation between the entanglement of formation EF and the conjugate function E∗ of the entanglement function E(ρ) = S(TrAρ). We then consider the conjectured strong superadditivity of the entanglement of formation EF (ρ) ≥ EF (ρI ) + EF (ρII ), where ρI and ρII are the reductions of ρ to the different Hilbert space copies, and pr...
