Negative masses, even if isolated, imply self-acceleration, hence a catastrophic world. Abstract The conjecture of the existence of negative masses together with ordinary positive masses leads to runaway motions even if no self-reaction is considered. Pollard and Dunning-Davies have shown other constraints as a modiication of the principle of least action and that negative masses can only exist...

Professor Zeide decries Popper’s view (Zeide 2010) of science. . . the view that science must be based on falsification rather than verification: scientific theories can be decidedly falsified, but never inductively verified : e.g. one negative instance (a black swan) is sufficient to reject a hypothesis (that all swans are white), while no number of white swans can prove it. Professor Zeide sa...

In the early 1980s, a method for controlling blast vibrations other than by modifying the Scaled Distance came into use. Research studies had indicated that blast vibration could be simulated by detonating a signature hole with the vibration monitored at critical locations, and then using a computer to superpose the waveforms with varying delays. By choosing delay times that create destructive ...

The authors of the paper “Mutiny on the Balint” in this month’s issue of Family Medicine report on an exploration with their family medicine residents of the purposes and methods of running a residencybased Balint group. A recent study from the United Kingdom by Pinder and colleagues addresses similar questions, most importantly: What is the relevance of Balint groups as a method by which to tr...

Quorum sensing (QS) plays an important role in virulence of Pseudomonas aeruginosa, blocking of QS ability are viewed as viable antimicrobial chemotherapy and which may prove to be a safe anti-virulent drug. Bioactive components from Piper betle have been reported to possess antimicrobial ability. This study envisages on the anti-QS properties of ethanolic extract of P. betle leaf (PbLE) using ...

Visual programming has particular appeal for explicit parallel programming, particularly coarse grain MIMD programming. Explicitly parallel programs are multi-dimensional objects; the natural representations of a parallel program are annotated directed graphs: data flow graphs, control flow graphs, etc. where the nodes of the graphs are sequential computations. A visually based (directed graph)...
