In this paper the dynamic analysis of a macro–micro parallel manipulator is studied in detail. The manipulator architecture is a simplified planar version adopted from the structure of the Large Adaptive Reflector (LAR), the Canadian design of next-generation giant radio telescopes. In this structure it is proposed to use two parallel redundant manipulators at the macro and micro level, both ac...

macroH2A is an H2A variant with a highly unusual structural organization. It has a C-terminal domain connected to the N-terminal histone domain by a linker. Crystallographic and biochemical studies show that changes in the L1 loop in the histone fold region of macroH2A impact the structure and potentially the function of nucleosomes. The 1.6-A X-ray structure of the nonhistone region reveals an...

The following propositions are true: (1) Let X be a set, p be a permutation of X, and x, y be elements of X. Then p +· (x, p(y)) +· (y, p(x)) is a permutation of X. (2) Let f be a function and x, y be sets. Suppose x ∈ dom f and y ∈ dom f. Then there exists a permutation p of dom f such that f +· (x, f(y)) +· (y, f(x)) = f · p. Let X be a finite non empty subset of R. The functor minX yielding ...

Plants species require macro and micro nutrients to complete the growth cycles such as photosynthesis, enzyme activities and secondary metabolite production. The objective of the present study was to investigate the effects of salinity on biomass as well as macro and micro nutrients uptake in the medicinal plant of Andrographis paniculata (AP). In this regard, a split plot experiment was carrie...

MzScheme’s continuation marks provide a flexible mechanism for implementing a number of useful language features and tools. We demonstrate the simplicity and utility of continuation marks by adapting them for JavaScript as frame-based stack marks using the Rhino implementation, showing a simple model of their behavior, and using them to build a toy debugger. Along the way, we discover a few int...

Purpose Successful commercialization is crucial to innovative firms, but further investigation needed on how diverse stakeholders can contribute the of a radical innovation that requires particular market creation support. This paper aims to, therefore, analyze key and their contributive activities in creation, particularly case innovations. Design/methodology/approach study relies qualitative ...
