Study of separation zone is so important in right-angled three-branch or four-branch open channel junctions. Some effective parameters in this case are inlet discharge ratio and flow depth which in this research the effect of inlet discharge ratio and weir height ratios (flow depth) on flow pattern and dimensions of separation zone has been simulated numerically. Investigation of numerical results showed that k-ω model well validated with experimental results and had good agreement, so that simulation error was less than 20%. Dimensions of separation zone in main and side channels were directly proportional with the inlet discharge ratio. Also as increases of height ratio of outlet weirs, flow depth increases and separation zone dimensions decreased. According to the analysis of numerical results, dimensions of separation zone in vertical direction, of the channel bed to water surface increased, so that for discharge ratio 0.6 and height ratio of outlet weirs 0.377, length of separation zone at the channel bed, 0.1 m up the bed and water surface was about 60 cm, 75 cm and 85 cm, respectively. So of the water surface towards the channel bed, length of separation zone decreased about %29.

Fortification is adding nutrients to a foodstuff. The nutrient may exist in that foodstuff natural1yor doesn't exist. SO, this process results in improvement of nutritional quality.The basic aim of food fortification with iron is to prevent iron deficiency in a population at longterm or middleterm .Vehicle and fortificant are two important factors in the fortification. Selection of suitable vehicle depends on vulnerable groups accessibility.Fortificant must have high bioavailability, cost benefit, and no effect on organoleptic specifications of the vehicle.Fortification is two types; public and target .Some countries have experienced iron fortification in national level. In Iran wheat is the best vehicle, because it is scanty food of a great number of Iran's people. But use of fortificant which can be suitable, is still debated.

Calcium is an essential element for living cells and plays an important role in muscle contraction, neurotransmitter secretion and blood coagulation. It has been cleared that deficiency in daily calcium intake can increase the probability of osteoporosis, hypertension, colon cancer, post partum depression and premenstrual syndrome. Dairy products are the most important sources for calcium. Calcium requirement is increased during years of growing to reach peak bone mass. It is increased in puberty and also during years after menopause and elderly to prevent osteoporosis and resultant fractures. Nowadays, peoples in the society are consuming synthetic drinks increasingly while liquids like milk and yogurt have been replaced by this type of drinks. With attention to great consumption of this type of drinks, it seems that placing some foods which have been fortified by calcium in daily regimen, could supply daily calcium requirements. The aim of this review article is to insist on calcium importance and food fortification with calcium and also to describe methods of fortification.

In this paper, a method is proposed to improve the results of the standard finite element method. L2 norm is used to determine the nodal error. In the next step, the appropriate order of the interpolation cover is seclected to be proportional to the nodal error and the results are corrected. The error computation procedure and the use of covering enrichment functions will continue until the error reaches the specified value. Cover enrichment interpolation functions will consider the effects of the adjacent elements of each node, in addition to the values obtained from the standard interpolation for each element. Computation rules are programmed in the matlab program and considered for the same examples. Comparison of the results of the proposed method with the exact solutions and the results of the methods proposed by the other researchers in the field of linear elasticity indicates the efficiency and accuracy of the proposed method.

Suspension and prospect both are elements of fiction literature, obliging the audience to continue the process of reading the story. This technique is mostly used in modern stories. It is also the most outstanding matter for making attraction and delisting the text for the reader. This research is a survey of suspension in the novel Anna Karenina by Leon Tolstoy, a well-known Russian thinker and novelist in the 19th century. Anna Karenina belongs to the perfect period of Tolstoy, especially after the period of the novel War and Peace. It is a story about the life of a lady named "Anna" who falls in mortal love after her marriage and having a child. She left her family because of her love and made some events as a result. We try to explain Anna's social position from the point of ethical and familial behavior in the text of Tolstoy. This research is descriptive and analytical. The factors causing the suspension are classified into two linguistic and non-linguistic sections, and then they are analyzed. 1-The main elements of the suspension Good writing is a collection of images and the use of writing tricks. A successful writer has a strong imagination and uses such techniques correctly because, between the right and wrong use of these tricks, the border is narrow. There is a possibility that the text may be vulgarized at any time by using them inappropriately or in excess. Suspension elements can be divided into two groups: linguistic elements and non-linguistic elements (each of which is divided into sub-sections): A) Linguistic elements: short sentences and answers, repetition of a word or sentence, ambiguous use of language B) Non-linguistic elements: rapid return to the past or future, step by step intensifying the conflict of the story, conflict and confrontation, sudden change of character, fear of an accident or the future, unusual plot or acting contrary to expectations, expectation and fear, symbols and signs Anna Karenina: The story takes place in several aristocratic Russian families of the 19th century when princes held a high position in society and aristocratic customs were considered the most important factor of social principle. The main plot of the story is the adventure of Anna Arkadyonna's love. She is the wife of Alexei Karenin, a Russian aristocrat, and falls in love with Alexei Krylovich Vronsky, a young army officer and the son of a St. Petersburg aristocrat. 2-Suspension in the novel Anna Karenina 1-2. Asking a general ambiguous theory or question The author challenges the reader by asking a general question or a general theory, and raises many questions and draws him in. 2-2. Ambiguity and suspension in the character Anna, Vronsky, Loin, Katie, Loin's mother (absent character) 3-2. Suspension in the accident This kind of fictive suspension happens through accidents as is the case with the death of a worker at a train station where Anna and Vronsky meet for the first time. Bringing this topic at first seemed pointless to the reader, while it was a prelude to expressing the nature of Anna's death and the end of Anna and Vronsky's love where it began. 4-2. Suspension in the plot Sometimes the events and their causes are unexpected for the reader. In their opinion, it is unreasonable and irrational because, in the real world, such conditions are impossible or rare. 5-2. Suspension in space and mood By describing a stressful and ambiguous space, the author could also convey the atmosphre to the reader. This atmosphere often becomes heavier when a character wants to make a decision or do something and encourages the reader to continue. 6-2. Suspension in place Sometimes the reader realizes and follows this secret in the places of events from the content of the author's words. The main suspense frequency of the story (suspension in the form), like other masterpieces in the world, was related to the superstructure and movement of narratives, narrative action, and the characters' complexity. There is, of course, a kind of content and intellectual suspension throughout the story, which happens in a problem or question form. This model of fictive suspension is shown through characters who have Tolstoy ideas. The story's theme is love, about a woman who has children and belongs to a believing family. The story is complex because of the actions and behaviors performed by Anna, her husband, and her lover.
