The effects of mandarin scions on peel components and juice quality parameters were investigated in this study. Peel flavor components were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. Twenty-seven, Tw...

these days, due to growing the e-commerce sites, access to information about items is easier than past. but because of huge amount of information, we need new filtering techniques to find interested information faster and more accurate. therefore recommender systems (rs) introduced for solving this problem. although several recommender approaches have proposed, collaborative filtering (cf) appr...

aim : the purpose of this study was to characterize phenotypically and genotypically the serotypes of the e. coli o111 associated with diarrheal disease and assess the variation among serotypes in terms of specific virulence factors and hela cells adherence patterns. background : escherichia coli o111 serogroups are prevalent in endemic or sporadic cases of diarrhea, especially in developing ar...

The diversity of immunoglobulin (Ig) functions may be explained by the peculiar structure of these flexible molecules. Heavy and light Ig chains are composed from compact stable immunoglobulin folds (IgF), or domains belonging to a large protein super family. Proteins composed from IgF have been found in various representatives of animal kingdom even those appeared during the very early stages ...

In this note we settle a question posed by Hobby and McKenzie in [2] on the nature of locally finite equational classes which satisfy some nontrivial congruence identity. We settle problem #14 from [2] by exhibiting a locally finite equational class V which omits types 1 and 5 and which satisfies some non-trivial congruence identity, but which contains a finite algebra having a type 4 minimal s...

Introduction The word brachydactyly is used to describe the hands and feet with shortened digits (brachy, meaning “short,” and daktylos, meaning “digit”) [1]. The digits themselves may be shorter than normal or they may appear small because of shortening of metacarpal and metatarsal bones in the hands or feet [1]. Most of the patients with brachydactyly do not require any specific treatment. Wh...

A collection of n distinct hyperplanes Li = {li = 0} ⊂ P , the (n − 1)-dimensional projective space over an algebraically closed field of characteristic not equal to 2, is a polar simplex of a smooth quadric Q = {q = 0}, if each Li is the polar hyperplane of the point pi = ⋂ j 6=i Lj , equivalently, if q = l 2 1 + . . .+ l 2 n for suitable choices of the linear forms li. In this paper we study ...

Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...
