The herbal compound consisted of a mixture of 500 mg of P. ovate husk in 30 m L water plus three drops of vinegar per dose, which was used as a mouthwash. Phytochemical and physicochemical tests of the compound were also performed. Twenty-eight patients who developed mucositis during the chemotherapy screening cycle were randomized to the herbal compound(n = 14) and placebo(n = 14) groups. They received herbal compound or placebo three times per day during their next chemotherapy cycle(cycle 1 of treatment). Patients were crossed over during cycle 2 of treatment and received the alternative therapy. An oral care protocol was prescribed to all patients in cycles 1 and 2 of the *** outcome measures: The patients were visited at baseline, the end of the first and second weeks of the screening cycle, and the end of the first and second weeks of each of two treatment cycles. The degree of mucositis was used as the main treatment outcome. Other indexes, such as the severity of pain, xerostomia grade and the quality of life were also ***: Compared with the placebo, the herbal compound significantly reduced the degree of mucositis,the severity of pain and the xerostomia grade;it also improved the patients’ quality of life(P < 0.05).Comparison between the screening cycle and placebo treatment group showed that the oral care protocol had a significant effect in the reduction of OM(P < 0.0

Creep rupture assessment for Level-2 PSA of a 2-loop PWR： accounting for phenomenological uncertainties

Nuclear Science and Techniques 2017年第8期28卷 117-125页

The Level-2 probabilistic safety assessment(PSA) of pressurized water reactors studies the possibility of creep rupture for major reactor coolant system components during the course of high pressure severe accident sequences. The present paper covers this technical issue and tries to quantify its associated phenomenological uncertainties for the development of Level-2 PSA. A framework is proposed for the formal quantification of uncertainties in the Level-2 PSA model of a PWR type nuclear power plant using an integrated deterministic and PSA approach. This is demonstrated for estimation of creep rupture failure probability in station blackout severe accident of a 2-loop PWR, which is the representative case for high pressure sequences. MELCOR 1.8.6 code is employed here as the deterministic tool for the assessment of physical phenomena in the course of accident. In addition, a MATLAB code is developed for quantification of the probabilistic part by treating the uncertainties through separation of aleatory and epistemic sources of *** probability for steam generator tube creep rupture is estimated at 0.17.

Iran is located in one of the seismically active regions of the world. Due to the high probability of earthquakes throughout the country and the potential for tsunami inundation along the coasts and offshore, comprehensive studies on theinteraction of these natural phenomena arc necessary, hi this study, the most conservative scenarios are determined for possible earthquakes within the Khark zone （Persian Gulf） *** on experimental relations between tile fault length, magnitude and displacement, which are paralneters for deter- mining tsunamigenic sources. Subsequently, the maximum height of tstmami waves are calculated based on the specitieations of the seismic source and its distance from the shore as well as the coastal slope. A zoning map of tsunami hazard is finally presented.

INVESTIGATING SILVICULTURAL CHARACTERISTICS OF YEW （TAXUS BACCATA L.） STAND USING FULL-CALLIPERING IN NORTHERN FORESTS OF IRAN

引用

International Journal of Biomathematics 2013年第1期6卷 105-114页

作者： MIR MOZAFFAR FALLAHCHAI seyed ARMIN hashemi GASEM RAHANJAM Department of Forestry Lahijan Branch Islamic Azad University Lahijan Iran MS. c Forestry Department of Forestry Lahijan Branch Islamic Azad University Lahijan Iran

In this research, some of site and silvicultural characteristics of Yew stand in northern forests of Iran was studied. For this purpose, compartment number 16 of district 4 Shir-ghalaye was selected. According to research purposes, stands with an area of 20 ha were chosen in center of the compartment and was separated from map. Due to restricted area of region and according to few number of Yew trees in the stand, the full-callipering method was conducted for measuring quantitative and qualitative characteristics. In the stand diameter at breast height （D.B.H.）, height and canopy diameter of all Yew trees were measured. The results showed that the diameter distribution curve and height distribution curve of Yew trees were similar to even-age forests curve. But according to average annual increment, mixture type of Yew trees in stand, diameter distribution of other species and low rate regeneration of Yew, it can be concluded that the studied Yew stand, is an uneven-age stand and because of low rate regeneration in previous years the number of young Yew trees were reduced and even-age forest curve was formed subsequently. The maximum height and diameter of Yew trees were recorded 26.8 m and 112 cm, respectively. Also, the number of trees per hectare and basal area per hectare of Yew trees were calculated 14.55 and 3.23 m2 respectively.
