abstract background: fresh bread has a short shelf life and by considering this matter, its acceptability by consumer dramatically would reduce by increasing the time between baking and consumption. use of frozen dough technology is one of solution for this problem. therefore in this current study the impact of freezing storage and pre-fermentation in sangak frozen dough and its bread was consi...

Background and objective: To determine the diagnostic accuracy and pitfalls of frozen section in ovarian tumors in one of the largest university affiliated gynecologic oncology centers in Tehran, and determine the cause of discrepancies. Materials and Methods: We retrospectively analyzed the results of frozen section and permanent diagnoses of ovarian masses by reviewing the reports in the dep...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...

In this paper, ‎The powers of fuzzy neutrosophic soft square matrices (FNSSMs) under the operations $oplus(=max)$ and $otimes(=min)$ are studied‎. ‎We show that the powers of a given FNSM stabilize if and only if its orbits stabilize for each starting fuzzy neutrosophic soft vector (FNSV) and prove a necessary and sufficient condition for this property using the associated graphs of the FNSM‎. ...

Background:The diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. In this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in Iran. Methods: We retr...

Box orbits in triaxial potentials are generically thin, that is, they lie close in phase space to a resonant orbit satisfying a relation of the form lω1 +mω2 + nω3 = 0 between the three fundamental frequencies. Boxlets are special cases of resonant orbits in which one of the integers (l,m, n) is zero. Resonant orbits are confined for all time to a membrane in configuration space; they play roug...

We study bifurcations from one-parameter families of symmetric periodic orbits in reversible systems and give simple criteria for subharmonic symmetric periodic orbits to be born from the one-parameter families. Our result is illustrated for a generalization of the Hénon-Heiles system. In particular, it is shown that there exist infinitely many families of symmetric periodic orbits bifurcating ...

Question. Does system (1.1) have periodic orbits when system (1.2) has periodic orbits? Recently, there have been a lot of researches in the literature on the periodicity of discrete-time dynamical systems [1, 3–8, 10, 11]. However, to the authors’ knowledge the above question has not received investigations, therefore in this paper we study the above question and obtain a fundamental result. O...

Let P+(n) be the Siegel parabolic subgroup of O(n, n), and P−(n) be the Siegel parabolic subgroup of Sp2n(R). In this paper, we study the coadjoint orbits of P±(n). We establish a one-to-one correspondence between the real coadjoint orbits of Sp2n(R) and the principal coadjoint orbits of P+(2n), and a one-to-one correspondence between the real coadjoint orbits of O(p, n− p) with p ∈ [0, n] and ...
