For any compact Lie group G, we give a description of genuine G-spectra in terms of the naive equivariant spectra underlying their geometric fixedpoints. We use this to give an analogous description of cyclotomic spectra in terms of naive T-spectra (where T denotes the circle group), generalizing Nikolaus–Scholze’s recent work in the eventually-connective case. We also give an explicit formula ...
There are many chemical molecules whose names are Cannabigerol (CBG), cannabidol (CBD), cannabichromene (CBC), tetrahydrocannabivarin (THCV), cannabigerovarinic acid (CBGV) and cannabidiolic acid (CBDA) derived from Marijuana. Theoretical methods were used to compare the chemical and biological activities of the six major molecules. Molecules were compared with their chemical activities using m...
Six fluorescent compounds were isolated and characterized in rhizomorph of A. mellea and were presented first as: F , F , F , MF , MF and MF . These compounds differed by Rf on chromatoplaque, max in UV spectra and ex, em and max in fluorescence spectra. Their GC-MS analysis indicated that F has a phenolic moiety and the other five are the benzenic derivatives. F compound was more f...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
tomato is a major fruit, as well as a major food science product. there is a need of determining the quality attributes of this fruit (nondestructively) due to the increasing demand of the in agro-industrially controlled areas. most of the commonly employed techniques are time consuming and involve a considerable degree of manual work. sample preparation, juice making, and laboratory tests ...
For any h in N , a graph G = (V, E) is said to be h-magic if there exists a labeling l: E(G) to Z_{h}-{0} such that the induced vertex set labeling l^{+: V(G) to Z_{h}} defined by l^{+}(v)= Summation of l(uv)such that e=uvin in E(G) is a constant map. For a given graph G, the set of all for which G is h-magic is called the integer-magic spectrum of G and is denoted by IM(G). In this paper, the ...
In this study, four arylazobenzylidene dyes (a-d) were synthesized with excellent yields in two steps using Knoevenagel condensation and azo-coupling reactions. Absorption spectra of these dyes with different substituents were investigated in organic solvents as a function of solvent polarity. The spectral features of synthesized arylazobenzylidene dyes were described according to azo-hydrazone...
This paper is about importing the stable homotopy theory of symmetric spectra [4] and more generally presheaves of symmetric spectra [8] into the Morel-Voevodsky stable category [9], [11], [12]. Loosely speaking, the latter is the result of formally inverting the functor X 7→ T∧X on the category of pointed simplicial presheaves on the smooth Nisnevich site of a field within the Morel-Voevodsky ...
