Dear editors, The way in which religious texts and sources depict the processes involved in the regulation of life is an interesting and rich topic. For example, the Holy Bible, the religious basis of Western civilization, is a document that includes references to medical, as well as historic cultural practicestu. Sun has already demonstrated that the Bible contains rich medical materials on different subjects in which the roots of modem medicine can be seen. We would like to expand this view to show that religious documents, with a focus on the Holy Bible, are illustrative of period understanding of life and human biological rhythmicity and chronobiology.

A contactor vessel was built to operate as either a mechanically or a conventional spouted bed for the purpose of analyzing the drying of pasty and granular materials under comparable conditions in both configurations. A classical conical–cylindrical spouted bed with a 60° conical base and an air inlet central orifice was modified to enable the switch by introducing in the vessel’s center an open helicoidal conveyor screw placed above the air inlet orifice. This screw is removable and conveniently returns the bed to its conventional spouted configuration. Experiments on drying solutions (calcium carbonate suspensions and skimmed milk) and granular materials (porous alumina particles) were performed for various bed parameter settings. The spouting pressure drop, outlet air temperature, and relative humidity were measured over time under different conditions. Mechanical agitation is proved effective in drying diluted carbonate calcium liquid suspensions and coarse porous alumina particles at an air velocity approximately 50% lower in comparison to drying in a conventional spouted bed. The conventional spouted bed performed better at drying liquid skimmed milk as the mechanical agitation combined with the axial inlet air flow is not effective in mitigating sticking and powder agglomeration in the bed when handling pastes of complex composition. Introducing mechanical agitation in the designed setup broadens the operating range of a conventional spouted bed with axial air flow in the inlet.

Conilon coffee represents almost 20% of all coffee production in the Brazilian territory;however, it is inexpressive in relation to the sensory quality when compared to Arabica coffee. It is noteworthy that the coffee from the species Coffea canephora PIERRE has a denser sensorial profile, is less sweet, less acidic and with strong pronunciation of the body at the time of tasting. This study has unprecedentedly applied the use of starter cultures (yeast) to optimize and modify the metabolic pathways and consequently the sensorial quality perceived by Q-graders. The experiments were conducted in a randomized block design with five replicates, in the 3 × 4 factorial scheme, with three fermentation times—24, 48 and 72 hours and four wet processing tests—Washed, Yeast fermentation, Fully washed without yeast and Fully washed with yeast. The sensorial results indicate a new perspective for the application of wet processing with starter cultures for Conilon coffee. They indicate gains in sensory scale, opening a new phase of studies on spontaneous and induced fermentation for Conilon coffee in Brazil and worldwide.

In[***.A 107012427(2023)],Baldwin and Jones prove that Uhlmann–Jozsa’s fidelity between two quantum statesρandσ,i.e.,F(ρ,σ)=(Tr√√ρσ√ρ)^(2),can be written in a simplified form as F(ρ,σ)=(Tr√ρσ)^(2).In this article,we give an alternative proof of this result,using a function power series expansion and the properties of the trace *** approach not only reinforces the validity of the simplified expression but also facilitates the exploration of novel dissimilarity functions for quantum states and more complex trace functions of density operators.

The consumption of specialty coffees has been growing year after year, indicating that several niches and market forms according to the sensorial orientation of the consumers, as well as the cupping tasters and agents are responsible for the composition of blends, and for the physical and sensory classification of the coffees in the industry. This study presented 5 methods of spontaneous and induced fermentation to different North American cupping tasters, in order to evaluate coffee quality potential, based on the Specialty Coffee Association (SCA) protocol. During the months of May to July of 2017, 150 coffee samples were evaluated. Initial results indicate that North American cupping tasters evaluated dry fermented coffees using yeast culture as superiors, in the sensorial aspect, than the more conventional methods in Brazil. Such indication opens new discussions on the acceptance of a determined product, followed by the potential for modification of the sensory route as of the fermentation that will affect the attributes.
