Titration of a trichloracetic acid filtrate of serum with EDTA is carried out at pH 9.8 using an excess of Calmagite indicator. Successive photometric readings of percentage transmission, made with an EEL titrator, are plotted against the volume of EDTA added. There is very little change at first while calcium is being complexed; the reading then decreases rapidly while magnesium is being titra...

~-Amino acid oxidase has been shown to have a critical temperature of 12-14’. Around this temperature it has been shown that a reversible change in protein conformation occurs; the change in enthalpy of the transition has been calculated as 78,000 cal per mole. Other parameters have also been shown to change on either side of this temperature; these include sedimentation constant, ultraviolet a...

At passage of an ultra-high-energy particle through a bent crystal coherent bremsstrahlung is emitted but with characteristic frequencies distributed continuously, in relation with the crystal bend profile. For practical crystals, such radiation can be calculated by the stationary phase approximation technique. The radiation spectrum averaged over the impact parameters is evaluated. Its charact...

Very few of the large number of major disasters in recent years have threatened the survival of the host region. Improvements in conditions underlying sustainability have helped in this regard, as has inherent and adaptive resilience associatedwithdisaster recovery. Sharp breaks from the past do not appear to be the norm, but opportunities for major transitions do increase in the aftermath of d...

We demonstrate theoretically that quantum dots in bilayers of graphene can be realized. A position-dependent doping breaks the equivalence between the upper and lower layer and lifts the degeneracy of the positive and negative momentum states of the dot. Numerical results show the simultaneous presence of electron and hole confined states for certain doping profiles and a remarkable angular mom...

Keeping Watch of Time: The Temporal Impact of the Digital in Cinema Humans are fundamentally analog creatures...Being in digital time differs from analog time in that events in digital time exist without an event horizon. Digital time occurs in sharp breaks and contrasts from one state to another without the flow of analog time, such as the slow procession of a sunset or the transition from a w...

Dependencies among software projects and libraries are an indicator of the often implicit collaboration among many developers in software ecosystems. Negotiating change can be tricky: changes to one module may cause ripple effects to many other modules that depend on it, yet insisting on only backwardcompatible changes may incur significant opportunity cost and stifle change. We argue that awar...

Abstract We investigate novel features of three-dimensional non-Hermitian Weyl semimetals, paying special attention to the unconventional bulk–boundary correspondence. use non-Bloch Chern numbers as tool obtain topological phase diagram, which is also confirmed by energy spectra from our numerical results. It shown that, in sharp contrast Hermitian systems, conventional (Bloch) correspondence b...
