Abstract There is increasing interest across Europe in adopting forest management strategies, which promote species and structural diversity through the use of irregular silvicultural systems, an approach often described as continuous cover forestry (CCF). However, there little information about proportion CCF practised continent or knowledge gaps other obstacles that limit its use. A survey re...

Coronary cameral fistula (CCF) is a rare anomaly, where a communication exists between an epicardial coronary artery and a cardiac chamber. Assessing the hemodynamic significance of the fistula is crucial to make a decision concerning the management process. We present two cases of CCF, draining into the left ventricle, in which the hemodynamic significance was assessed by a fractional flow res...

Coronary-cameral fistula (CCF) is an anomalous connection between a coronary artery and a cardiac chamber or major vessel, seen in about 0.8% of the cases undergoing coronary angiography. Most patients are asymptomatic and diagnosis is made incidentally during coronary angiography. We present an image case of CCF which was found incidentally during pre-liver transplantation work up.

BACKGROUND Reducing pauses during cardiopulmonary resuscitation (CPR) compressions result in better outcomes in cardiac arrest. Artefact filtering technology (AFT) gives rescuers the opportunity to visualize the underlying electrocardiogram (ECG) rhythm during chest compressions, and reduces the pauses that occur before and after delivering a shock. We conducted a simulation study to measure th...

Addition of an excess of t-butyl isocyanide to solid Mo2 (0, CCF3 )4 or MO?_ (0, CMe)4 gives (t-BuNC), Mo(Oz CCF3 )* or (t-BuNC), Mo(Oz CMe), , respectively. The quadruple bond in K4 MO* Cl8 or Cl4 MO, (n-Bus P)4 also can be cleaved by an excess of t-butyl isocyanide to yield (t-BuNC), MoCl, _ The anionic ligands can be exchanged with ammonium hexafluorophosphate in presence of excess t-BuNC to...

Purpose: To report a rare case of slow progression carotid cavernous fistula (CCF) with central retinal vein occlusion (CRVO).Case summary: A 66-year-old man presented conjunctival injection and proptosis in the right eye. Best-corrected visual acuity was 0.8 0.5 left eye, respectively, vessel enlargement subconjunctival hemorrhage were observed eye on slit lamp examination. Due to suspicion CC...

The inverse spinel Cobalt ferrite (CoFe2O4, CFO) is considered to be a promising alternative commercial graphite anodes for lithium ion batteries (LIBs). However, the further development of CFO limited by its unstable structure during battery cycling and low electrical conductivity. In an effort address challenge, we construct three-dimensional hierarchical flower-like nanoclusters (CFO NCs)-de...

News recommendation has become a big attraction with which major Web search portals retain their users. Two effective approaches are Content-based Filtering and Collaborative Filtering, each serving a specific recommendation scenario. The Content-based Filtering approaches inspect rich contexts of the recommended items, while the Collaborative Filtering approaches predict the interests of long-...

The critical Casimir force (CCF) arises from confining fluctuations in a fluid and thus it is fluctuating quantity itself. While the mean CCF universal, its (static) variance has previously been found to depend on microscopic details of system which effectively set large-momentum cutoff underlying field theory, rendering potentially large. This raises question how properties are reflected exper...
