Background and objectives: Increase in global warming and environmental issues, public opinion pressure, especially in urban areas near cane fields, the necessity of replacing green harvesting sugarcane (Saccharum Officinarum) instead of burning up is increasing. To set on fire cane fields also due to lose about 20 T ha-1 herbaceous (Trash blanket) remains can change to organic matter and help to soil fertility and sustainable production of sugarcane in Khuzestan. Materials and methods: To evaluation quantity and quality indices at harvesting time in green harvesting method and comparison with burnt harvesting losses a test performed in 2015-2016 growing season at Imam Khomeini Agro Industry Company. The experiment design was a split plot based on complete randomized block with four replications. Three sugarcane cultivars were as main plots and five harvesting methods and ratooning after harvesting were as sub plots considered. Infield losses such as complete cane, chopper cane, unravel cane, uncut cane, total losses, pol percent and cane yield was studied in test units. A SAS (v 9. 2) software was used for accounts statistical and LSD test for means comparison. Results and Discussion: The results showed that cultivars had significant effect on all of measured characteristics. The highest and lowest unravel cane loses was observed in cultivar of CP73-21 (2. 65 T ha-1) and CP48-103 (1. 23Tha-1), respectively. Maximum total of losses belong CP73-21 cultivar (12. 14Tha-1) and minimum (4. 46Tha-1) belong CP48 cultivar. Because of difference between sugarcane cultivars in terms of cane length, leaf numbers, maturation stage period and tolerance to logging, these characteristics have important role in field losses. The highest unravel cane losses belong whole of green harvesting methods (without significant different between themselves) with nearly (2Tha-1) and the lowest unravel cane was observed burnt harvesting (1. 35Tha-1). Green harvesting methods had more losses than burnt harvesting method. Because leaves and top are green at harvesting time in green harvesting method so losses amount in green harvesting method is higher than burnt method. The highest pol percent belong pre and middle mature cultivar. Method harvesting had not significant different on pol percent. The highest cane yield was observed in CP69-1062 cultivar (92. 87Tha-1) and the lowest cane yield was observed in CP73-21 cultivar (65. 4Tha-1). Average yield of burnt harvesting was 83. 19Tha-1 and average yield of total green harvesting methods was 73. 68T ha-1. Generally, yield of green harvesting methods had yield about 11% lower than burnt harvesting methods. Conclusion: Because researches about green harvesting sugarcane start lately in Iran and because infield losses is higher in early maturity cultivar than other cultivars and need to technical changes about sugarcane harvesters for field losses decrease, current green cane harvesting must be start with middle maturity and late maturity cultivars.

Background & Aim: Mechanical, intermittent and precise microbial plaque is one of the main stages of chronic periodontal disease treatment. Due to the increasing use of herbal toothpaste, this study was conducted to compare the effects of Crest 7 Complete with Silca herbal toothpaste.Material & Method: In this cross-over clinical trial study, 60 dental students (14 males and 46 females) with a mean age of 25.38.8±1.588 were selected. The plaque index was recorded, scaling and prophylaxis was done. The toothpastes (Silca and Colgate) were randomly assigned to individuals. After 14 days, the plaque index was registered. Scaling and prophylaxis were performed again and the second toothpaste was given. Changes in plaque index were analyzed by Mann-U-Whitney and Wilcoxon tests.Results: Plaque index for the Crest was 0.91±0.23 and for the Silca was 0.85±0.20 and the difference was not statistically significant (p<0.4).The changes in dental plaque for the Crest toothpaste was 0.81 and for the Silca toothpaste was 0.76, the changes were not statistically significant (p<0.4). Within each group, Crest and Silca toothpaste reduced dental plaque respectively from 1.67 to 0.91 (48.5 percent) and from 1.65 to 0.85 (51.5%) that the changes were statistically significant ( p<0.02).Conclusion: Silca herbal toothpaste similar to the Complete crest 7 is effective in controlling dental plaque.

Introduction: Traumatic dental injuries occur in children with great frequency because of falls in schools, fighting or falls during riding a bike, making it necessary to visit a dentist. One of the most serious dental injuries is avulsion in which the tooth completely comes out of the dental socket. In the clinical view the socket is empty or it is filled by a clot. These injuries make the child and the parents extremely anxious because if avulsion is not managed immediately and properly it has dangerous side effect, like loss of the permanent tooth, esthetic problems, loss of self-confidence, malocclusion and malnutrition. The aim of this literature review was to collect the latest guidelines about avulsed teeth.Review Report: Electronic search was carried out in Pubmed and Medline for controlled randomized clinical trials and review articles and American Association of Endodontists guidelines about diagnosis, treatment plan and follow-up of avulsed teeth. Articles were collected until the end of March 2013.Conclusion: Since general dentists face this condition more than others they are in the first line of treatment such children and can pervert most of the side effects with proper treatment. Therefore, having the latest knowledge about diagnosis, treatment plan and follow-up of avulsed teeth is essential for all the general dentists and specialists.

In addition to its natural and initial functions, walking stick or cane, as an important cultural and mythical symbol, has a great presence in myths and religions. Once upon a time, it was used as a simple tool in routine tasks; but gradually it acquired new functions in the life of people. In subsequent periods and in close relation with the intellectual development of man, it emerged in symbolic form. Symbolic functions of cane have been changed in different mythical and religious periods. Sometimes due to these changes, its connection with its roots is cut away and appears in a different form. On the other hand, along with technological advances, the functions of cane are assigned to more advanced instruments such as spear, bow, sword and modern weapons. In the present article the attempt is made to explain the role of cane and its various functions in myths and epics in conjunction with the gods, kings and heroes. Also, its presence in different religions and its symbolic roles as well as gradual change of these roles are considered.

Sugar cane juice can be better clarified and decolorized by ultra-filtration than by other techniques. In this article application of ultra-filtration in the clarification of cane sugar juice has been described, Several experiments were car­ried out on the raw sugar juice, and decolorization and permeate flux have been studied in this system; furthermore by consideration of different theoretical models, gel layer model have been proposed for this system.

Bicornuate uterus has two symmetric uterine cavities that are fused caudally and have some degree of communication between two cavities, usually at the uterine isthmus. A complete bicornuate uterus has a seperatory cleft of tissue that is extended to the internal OS. Lesser degree of septation of the two uterine horns has constitution, a partial bicornuate uterus. Bicornuate uterus is a class of four anomaly of American fertility society classification of mullerian anomalies. Here we report a case of a 19-year-old female patient with complaint of abdominal pain and spotting since 4 months ago. In sonography it revealed bicornuate uterus and hematocolpos. The patient underwent general anesthesia and examination that reveal the transverse vaginal septum. Septum removed by resectoscope was successful.

In this paper, we introduce the gn- complete hyper group and gn*-complete hyper group. The hyper group H is called gn - complete hyper group if for every sÎ Sn (z1,z2,….zn ) Î Hn we have Pni=1 Zs(i)= g (Pni=1 zi ) we prove that if H is a gn -complete hyper group then g*=gn. If H is a g2 complete hyper group then H is a complete hyper group and we have gn=g , gn*¹ gn*-1 finally we prove that H is a gn*- complete hyper group if and only if it is an Abelian group.
