which is considerably longer than previous measurements at the same mesh Reynolds number (Re = 48260). The stratified experiment resulted in a decay rate virtually identical to that of the neutral case through W,t/M = 275. However the decay rate sharply decreased after this time when the field of turbulence was replaced by internal gravity waves. A critical Richardson number marks the transitio...
Determination of landscape evolution is useful to well understand the physical environment and it also enables us to conduct the soil related studies. The objective of this study was to establish the historic evolution of Zayandeh-rud Valley from late Tertiary to Quaternary. To achieve this objective, the spatial structure of a representative area of Zayandeh-rud Valley in three dimensions was ...

When fluid flows through a channel, pipe, or duct, there are two basic forms of motion: smooth laminar motion and complex turbulent motion. The discontinuous transition between these states is a fundamental problem that has been studied for more than 100 yr. What has received far less attention is the large-scale nature of the turbulent flows near transition once they are established. We have c...
the present study is paid to the evaluation of the welfare program of the unemployment insurance in iran. the main purpose which was the main reason for performing this thesis, was the unemployment insurance plan’s challenges in iran such as financial problems of this plan, prolongation of the credit receipt for some insured people, unemployment slow exiting from the unemployment insurance fund...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
A rite of passage is a ritual event that marks a person's transition from one status to another, including birth, coming-of-age, marriage and death. One of the rite of passage is funeral and its Rituals .A funeral is a ceremony for honoring, respecting, sanctifying, or remembering the life of a person who has died. Funerary customs comprise the complex of beliefs and practices used by a culture...
Plants have a remarkable ability to react to seasonal changes by synchronizing life-cycle transitions with environmental conditions. We addressed the question of how transcriptional re-programming occurs in response to an environmental cue that triggers the major life cycle transition from seed dormancy to germination and seedling growth. We elucidated an important mechanistic aspect of this pr...
This article deciphers and analyzes a previously unknown Sassanian mint location represented by the inscription WLČ., based on the analysis of a Middle Persian inscription found in Persepolis, and on the linguistic changes that occurred during the transition to modern Persian. Evidence is presented to show that this previously unknown Sassanian mint designation corresponds to the modern-day ci...
Abstract The facciata double meaning as façade and outer appearance embodies the Italian city-state’s political, cultural, social values that Leon Battista Alberti outlined in his famed De re aedificatoria libri decem (1485). This concept lies at heart of Florence’s urban fabric: one early cradles Renaissance architecture originated from artistic expenditure prosperous families including, Medic...
