This research is aimed to eradicate the biofilm formed by bacteria causing wound infection through using proteinase K enzyme. For this purpose six different concentrations of proteinase K were used for the degradation of biofilm produced by Staphylococcus aureus and Pseudomonas areuginosa. These two species are the most common abundant bacteria causing infection by biofilm. Each of the concentrations was kept in contact with the pathogenic bacteria for 1, 2 and three hours. After 3 hours of incubation period the concentration (4 µg /ml) resulted in the highest eradication ability against S. aureus biofilm, while the same concentration was no significant in the eradication of Pseudomonas aeruginosa biofilm.

Abstract: Background: The aim of this review was to summarize the most important traditional medinical herbs and plants which are using in different parts of the world with focusing on a green anticancer approach. \nAim: We used PubMed, Research gate and Google to search for and collect scientific publications for a full evaluation of current evidence in the literature indicating the potential role of Chinese herbal medicines.\nResults: The most important influence of Chinese herbal medicines on cancer treatments are prevent cancer occurrence, reduce post operative complications, reduce side effects, reduce post operative recurrence, maintenance therapy, slow down tumor growth, palliate symptoms and prolong survival. Alkaloid anti-cancer compounds are pyrrolidine, pyridine, tropane, piperidine, pyrrolizidine, quinolizidine, indolizidine, isoquinoline, oxazole, isoxazaole, quinazoline, quinoline, indole serine, purine, β-phenylethylamine, colchicine, benzylamine, abornin, pancratistatin and narciclasine.

It is a broad group of various diseases typified by unregulated cell growth. The role of plants, especially traditional herbs as a source of organic medicines has been prevalent in many societies, especially in Eastern medicinal science for thousands years. Traditional medicine herbs and plants which have both antiviral activity and ability to promote immunity, would have possible inhibition ability in the initiation and promotion of virus-associated cancers. Medicinal plants should always consider as a great source of novel chemical constituents with anti-cancer effects.

Diversion dams and barriers are considered structures that prevent fish migration along the river. To resolve this problem in the design of dams, hydraulic structures are built as a fishway near the dam. Pool and weir is a type of fishways that make possible migration of fish to upstream of the dam. Velocity, water depth and turbulence are the effective parameters in swimming of fish. In this paper, the three-dimensional equations governing shallow water in weir and orifice fishway are solved with suitable models of turbulence that flow pattern and turbulence can be calculated. The results of simulation of flow were compared with results of field study by Micromollineh. The results show that the turbulence model in numerical simulations can be used as an effective tool for design parameters in pool and weir fishway.

Leadership is a collection of talents and skills that can learn and teach. The most important skill of any successful manager and leader is the learning skill; therefore anyone has the potential to become a successful manager and leader through learning. It is important to identify learning sources for leadership skills. Before explain the issues and challenges in public administration and public sector. It seems that learning leadership can be a proper solution to deal with existing challenges and solve problems. Research goal is to identify and explain leadership skills learning sources and offering a model based on it for public administration and public organizations. The approach of this study is qualitative and the Delphi method used. A sample of 25 professors with an expert\'s degree in organizational behavior with managerial experience selected. Two sources identified for learning leadership skills: Person-based and environment-based sources. Learning begins with self-knowledge and enriched by interacting with the external environment. Finally leadership skills learning needed to manage organizations and public administrator completes.

Work is one of the most important and positive values for people in many societies and cultures. However, the passion for work can often become obsessive: in this case work activities take up a disproportionate space in the person’s identity and cause conflicts with other life domains .This over-commitment of energies and time to work has been used in literature to describe the notion of workaholism .\nObjective of the present survey is to study degree of workohalism among professors in Islamic Azad Universities of Isfahan Province, Iran. It was conducted using descriptive-field methodology. Historical study method like scientific books and journals was used to collect data related to research literature and Wart standard questionnaire was applied to collect data to confirm or reject research hypothesis. Statistical population of the survey included all professors Islamic Azad Universities of Isfahan Province and random sampling method was used. Results indicate degree of workohalism among professors in Islamic Azad Universities of Isfahan Province is more than the average level.

Regional flood frequency analysis (FFA) is the one of methods that uses for estimation in ungaged sites. Determination of homogeneous regions is base of regional analysis. In this research for identifying homogeneous regions, Ward hierarchical cluster and K-means methods were used. From rank and product moment correlation methods, there is high correlation between annual maximum flood and catchment\'s area and slop, so the bios of area parameter between clustering parameters was selected two. The appropriate number of homogeneous regions was determinate from nonhomogeneity test, discordancy measure and error estimation. In this research the stations with high discordancy measure, more than 2 and 3, and sum of discordancy measure were determinate. From the results, only K-Means method with four and five homogeneous regions, have low discordancy measure. Also in these alternatives, the sum of discordancy measure is lowest. Determination of nonhomogeneity measure shows that divided of studied basin in to five regions is the best and these regions have lowest nonhomogeneity measure. Also error between observed and estimated data, in regions that have low nonhomogeneity and discordancy measures, were low. Mont Carlo simulation and error analysis methods were used to evaluation of uncertainty in the choice of the clustering method and number of clusters for regional FFA with L-moments. The results show that, the various clustering method and number of clusters effects on goodness of fit measure, volume of estimated discharge and error of estimations, specific in high return periods.

More than 2 million tons of agricultural wastes are produced annually in\nMalaysia. These agricultural wastes provide feedstock for biochar production, which\ncontributes insignificant net carbon dioxide to the atmosphere after soil incorporation.\nThree kinds of primary biochar were used in this study, namely, empty fruit bunch\nbiochar (EFB), wood biochar (WB), and rice husk biochar (RHB). EFB and WB were\nproduced by slow pyrolysis, whereas RHB was produced by gasification. This study\naimed to investigate the influence of slow pyrolysis and gasification methods on\nbiochar chemical characteristics and short-term soil stability. Results showed that the\nkinetic parameters of C mineralization, which was calculated by fitting the three-pool\nkinetic model to evolved CO2–C under field conditions, suggested a tri-phasic Cmineralization\nprocess (labile, unstable, and recalcitrance carbon). Our estimates\nreflected the existence of a very labile C fraction in RHB with a very small decay\nconstant K3. Fourier transform infrared spectroscopy and x-ray diffraction showed the\nthree phase transitions of the biochars from the microcrystalline C of the labile\nfraction to the largely amorphous intermediate C of the unstable fraction and\nformation of turbostratic crystallite C in the recalcitrant fraction. We concluded that\nEFB and WB decomposed faster than RHB. Therefore, RHB was a suitable option for\nC sequestration in soil.

The Cretaceous deposits in Morakan, located in the northeast of Khoy, a town in western Azarbaijan province, Iran, are primarily made up of carbonate rocks. These deposits, which are of 717meters thick, lie on the clastic facies of Jurassic beneath the Plagic beds of the Upper Cretaceous. To investigate the facies, sedimentary environment and sequential stratigraphy of these successions, a stratigraphic section was made in the south of Morakan village. Carbonate facies in this section have deposited in open marine, Bar, Lagoon, and Tidal flat facies belts. The study of these facies and comparing them with old and modern sedimentary environments reveal that these successions have deposited in a carbonated platform of rimmed shelf type. The study of the vertical succession of microfacies shows four main sequences in the form of system tracts of TST and HST, which are made up of shallowing and deepening parasequences. The first lower boundary of the sequences is of the type SB1 unconformity, and other identified sequences are of the type SB2 unconformity
