This research was conducted during the 2018 and 2019 seasons, aim of to study effect each different drying methods (drying in shade, direct sunlight, electric ovens, solar dryer) storage periods (0, 2, 4 6 months) on quality Roselle (Hibiscus sabdariffa L.) for both variety cultivars Sabhia 17 Dark Light. The results showed that method shade gave best most characterizes studied varieties times ...

In the last decades, researchers have developed new materials to improve the quality of human life. Owing to the frequent occurrence of bone fractures, it is important to develop plate materials for the fixation of fractured bones. These plate materials have to be lightweight, compatible with human tissues and ought to allow stiffness. Natural fibers have the advantage that they are renewable r...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

This paper surveys some combinatorial aspects of Smith normal form, and more generally, diagonal form. The discussion includes general algebraic properties and interpretations of Smith normal form, critical groups of graphs, and Smith normal form of random integer matrices. We then give some examples of Smith normal form and diagonal form arising from (1) symmetric functions, (2) a result of Ca...

Edible flowers, including roselle, contain a varied composition of phenolic compounds that may inhibit the oxidative stress mechanism. Roselle-based tisane with appealing sensory properties is commonly consumed worldwide. However, conventional hot-brew method ruin stability thermolabile during preparation. Hence, this study aimed to develop new alternative brewing linked cold-brew method, which...

To Doron Zeilberger, with our warmest regards, on the occasion of his sixtieth birthday. Abstract. The secant and tangent numbers are given (t, q)-analogs with an explicit com-binatorial interpretation. This extends, both analytically and combinatorially, the classical evaluations of the Eulerian and Roselle polynomials at t = −1.

Background & Aim:Extracts of Roselle calyx,   possess compounds which could be considered as a great source of natural antioxidants.   In this project, antioxidant activities, phenolic compounds content and their   correlation analysis on calices of Roselle (Hibiscus sabdariffa) was investigated.  Experimental: Total polyphenolic compound, flavonoids and anthoc...
