Low-energy cardioversion of ventricular tachycardia: When less is more
Herein we report the case of a patient who was admitted in ventricular tachycardia after having received multiple ineffective (and sometimes pro-arrhythmic) high-energy internal shocks from his ICD and who was finally successfully treated by a commanded low-energy internal cardioversion of 0.6 J. This article revisits the use of low-energy shocks and discusses their electrophysiogical mechanism...
متن کاملHow to Use MRP in Continuous Production Industries When Order Type is Lot for Lot
The Materials Requirements Planning (MRP) method that is applied in production planning and management has some weaknesses. One of its weaknesses is that the time in MRP method is discrete, and is considered as time period. Hence we are not able to order our requirements at irregular time moments or periods. In this paper, a new form of MRP is introduced that is named Continuous Materials Requi...
متن کاملWhen every $P$-flat ideal is flat
In this paper, we study the class of rings in which every $P$-flat ideal is flat and which will be called $PFF$-rings. In particular, Von Neumann regular rings, hereditary rings, semi-hereditary ring, PID and arithmetical rings are examples of $PFF$-rings. In the context domain, this notion coincide with Pr"{u}fer domain. We provide necessary and sufficient conditions for...
متن کاملRange Distributions of Low-energy Nitrogen and Oxygen Ions in Silicon (RESEARCH NOTE)
The range distributions of low-energy nitrogen and oxygen (2-3 keV) ions is silicon are measured and compared with these available in theories. The nitrogen distribution is very close to a Gaussian distribution as predicted by theory. The oxygen profile however, indicates a surface localized peak along with a shoulder and a long tail into the sample. The surface peak is beleived to he the resul...
متن کاملConspecific and Heterospecific Information Use in Bumblebees
Heterospecific social learning has been understudied in comparison to interactions between members of the same species. However, the learning mechanisms behind such information use can allow animals to be flexible in the cues that are used. This raises the question of whether conspecific cues are inherently more influential than cues provided by heterospecifics, or whether animals can simply us...
