Effect of Arsenic Content in Shour River on Groundwater Resources in Irrigated Area at Rafsanjan Plain

Jafar Rahnamarad and Reza Derakhshani
This study was conducted to evaluate effects of irrigation of 300 ha of pistachio growing lands with water from the Shour River on groundwater resources of the Rafsanjan plain. The comparatively high prevalence of arsenic-related cancers, the high concentration of arsenic in the nearby plains, and the recharge of the Shour River through Sarcheshmeh Mountains composed of volcanic hosted massive sulfide ore deposits (VMS), are the authors' motivations for reviewing the concentration of this substance in the Rafsanjan groundwater and the Shour River. Arsenic concentration was measured in 41 samples from the river and groundwater resources using inductively coupled plasma mass spectrometry. The results were evaluated through iso-concentration maps, correlation diagrams, and multivariate statistical methods. Accordingly, the concentration of arsenic in the Shour River and the Rafsanjan groundwater ranges from 7.5 to 278µg/l with an average value of 97.82µg/l. These levels are much higher than that acceptable for drinking Water (10µg/l). The high arsenic content of groundwater of the Rafsanjan plain are ascribed to both the decomposition of sulfides present in mountainous volcanic rocks and the Shour River pollution in the vicinity of the Sarcheshmeh copper mine caused by Acid mine drainage (AMD) - which is regarded as the worst environmental problem related to mining that affects surface and groundwater quality- originating from waste dumps in this mine.

Effet des Margines et de Deux Qualités d’eau D’irrigation sur les Composantes de Rendement d’une Variété Locale d’Orge (Hordeum Vulgare): Essai en Pot.
Raja Dakhli, Ridha Lamouri and Houcine Taamallah
Dans un contexte actuel ou l’agriculture doit produire d’une façon durable en particulier en zones arides caractérisées par un déficit hydrique sévère et des sols généralement dégradés. La recherche des solutions permettant de contourner ces contraintes s’impose afin d’assurer une production agricole équitable qui respecte l’environnement dans un cadre de développement durable. Dans ce cadre l’idée de la valorisation des Margines comme amendement organique en agronomie a été proposé comme alternative prometteuse pour la restauration de la fertilité des sols et l’amélioration de la production agricole. L’étude de comportement d’une variété locale d’Orge (Hordeum Vulgare) irriguée à l’eau de robinet (2,8g/l) et à l’eau de forage (7,4g/l) en présence des différentes doses de margine a fait l’objet de notre travail de recherche. Trois doses de Margines ont été appliquées à raison de T1 (50 m³/ha), T2 (100 m³/ha) et T3 (200 m³/ha).Le rendement en paille, le nombre d’épis/m², le rendement en grains, le poids de 1000 graines ont été les paramètres étudiés. L’essai en pot a été conduit aux laboratoires de l’Institut des régions arides au sud Est tunisien. Les résultats de cette étude montrent que l’application des Margines à des fortes doses provoque une réduction hautement significative de toutes les composantes du rendement étudiés à savoir le nombre d’épis/m², le nombre des graines/épis, le rendement en matière sèche et le rendement en grains. Par ailleurs, cette réduction est plus préjudiciable lorsque les Margines sont en interaction avec l’eau d’irrigation chargée de forage. Globalement et comparé à l’irrigation à l’eau de robinet, l’eau de forage (chargée) a engendré les réductions les plus préjudiciable.

Polymeric Reagent as a Depressant in Pyrite Flotation
Hyonseung Dho
The investigation was initiated to on the role that starches and starch derivatives play as a depressant on pyrite. The depressant action was studied through the flotation charateristics, electrochemical behaviors, zeta potential measurements.The flotation results revealed that starch polymer, CMC-g-PAM showed some promising in depressing pyrite. Adsorption of CMC-g-PAM took place through specific interaction with ferric hydroxide species that result from the oxidation of pyrite surface. The electrochemical results showed that pyrite was oxidized at an alkaline pH. At the neutral pH, ferric hydroxide from the oxidation pyrite was coated on the pyrite surface to make the pyrite surface more hydrophillic. The adsorption of CMC-g-PAM might be an effective depressant for pyrite. Pyrite from the electrochemical behaviors results was started to oxidized 0.1 volt at pH 4. At this pH, pyrite was floated 95%. At the range of -0.3 volt to +0.2 volt at pH 9, pyrite was depressed almost 80% in the presence of 20mg/l CMC-g-PAM.
Keywords: Pyrite, Flotation, Adsorption, Cyclic Voltammetry, Depressant. CMC-g-PAM.

An Efficient Routing in Mobile Adhoc Networks (MANETs) using Hybridisation of Fuzzy ACO with Adaptive Genetic Algorithm
B. Nancharaiah and B. Chandra Mohan
In Mobile Adhoc Networks, discovering and maintaining routes between mobile nodes in a dynamic topology with possible links, using minimal resources is desirable. However, routing in MANETs has some problems in path selection process. Several techniques were implemented to optimize the routing parameters with a multi-objective function. Recently, Adaptive Genetic Algorithm (AGA) with Dijkstra algorithm using reliability and delay measures in routing as parameters, were implemented. But, it has some limitations in determining the nearest node information. A hybrid model of fuzzy based Ant Colony Optimization with AGA is proposed in this paper. Performance of the proposed algorithm is compared with AGA. An improvement is observed in delay and cost. Proposed hybrid method requires minimum delay compared to AGA. The proposed hybrid algorithm (AGA with FACO) has minimum cost compared to AGA and Fuzzy ACO.
Keywords: Fuzzy ACO, Adaptive Genetic Algorithm.

Using Common Storage for Sharing Data in Mobile Ad Hoc Networks
Hamed Izadi, Mehdi Sharafi and Sam Jabbehdari
Mobile ad hoc network is a wireless network in which there is no centralized infrastructure and hosts change their place each moment, thus the typology of network varies. Since in this network the host’s energy is supplied by battery, limitation of host energies matters. Data communication is one of chief factors in consuming hosts’ energies in the network. As a result, establishment of related energy –based protocols is one of important research areas on mobile ad hoc networks. In the present research, a solution for modification of hosts’ access to the available data is provided in a way that through optimum consumption of energy will have access to data. Moreover, data replication with minimal redundancy and maximum effect occurs in the network. The obtained results of simulation indicate modification in rate of access to data as well as decrease of host energy consumption.

The Toxic Effects of Two Commercial Herbicides Systemic Chevalier and Cossack in Antioxydant Activities Catalase Ascorbate Peroxydase and Gaiacol Peroxydase of Durum Wheat (Triticum Durum Desf.)
Nabiha Belahcene, Mohamed Réda Djebar, Zenati Noureddine and Houria Berrebbah
The present study has evaluated effects of two herbicides systemic Chevalier and Cossack concentrations used for controlling cereals growth, on selected metabolic and stress- related parameters in wheat (Triticum durumDesf.) cultivar Carioca, Sersou and Wercenisplants. Our results show that the Chevalier and Cossack induced oxidative stress triggered significant changes in activities of catalase, ascorbate peroxidase and gaïacol peroxidase. Activities of the antioxidant enzymes show a general increase at low herbicide concentrations and a decrease at high levels. The results of the response of each variety to xenobiotic present indicate that, Carioca tolerated Cossack by intense activity guaiacol peroxidase, but in the presence of Chevalier, this variety adopted a different strategy based on a strong catalase activity and guaiacol peroxidase. The response of Sersou in the presence of Chevalier is essentially based on an activity guaiacol peroxidase whereas the contact of the Cossack, it rests on peroxidases. Under the treatment by Cossack, Wercenis exploit peroxidases and catalase, which have high values and in the presence of Chevalier catalase and guaiacol peroxidase.

New Design and Implementation of MLFQ Scheduling Algorithm for Operating Systems using Dynamic Quantum
Mohammad R. Kadhum and Seifedine Kadry
The new design of multilevel feedback queue will depend on usage new technique in computing the quantum to produce (ADQ) Auto Detect Quantum which is relied on the burst of each process has enrolled to the system. By summating the burst time of each process has arrived and dividing it by the number of available processes, we can obtained the dynamic quantum in each level of scheduling . The processes are scheduled and shifted down from queue to other according to their remaining bursts time that should be updated periodically. Every queue has a unique auto detected quantum which is gradually increased or decreased from top level to bottom level queues according to the case of arriving processes. Depending on the results of graphical simulating algorithm on cases study, we can discover that a dynamic quantum is very suitable to accommodate low priority processes that still for a long duration to complete their requests, i.e. avoid the starvation of CPU- bounded processes. Although, it stills compatible with high priority processes (I/O-Bounded) to provide a fair interactivity with them. In comparison to traditional MLFQ the performance of the new scheduling technique is better and practical according to the applied results. Additional, we developed suitable software to simulate the new design and test it on different cases to prove it.

Studying Freedom of Information in Iran
Omid Karimian
Right of information is one of the fundamental rights of each human. This right indicates that any human has right of access to the information which is related to him/her and affects his/her life. Study of limits of freedom of information is one of the important issues which have been presently discussed in different legal systems of the world and in international documents. Although principle of freedom of information has been expressly accepted in Constitutional Law of Iran, this freedom is not absolute and exceptions have been exerted on it. This research which has been conducted with analytical –descriptive method based on library data studied right of free access to information and its exceptions in Iran legal system and finally dealt with its shortcomings and suggested some points for improving this principle in Iran local law.

Right of Access to Information, Fundamentals, Barriers and Necessities in International Law
Omid Karimian
Right of the public access to official information or ability of citizens to gain access to the information held by government is called freedom of information. Of course, this right is not unconditional and some regulations should be observed for it. It seems that this right can be regarded as infrastructure of information freedom principle during information explosion and new communication era which requires free access to information. This research which has been conducted with analytical –descriptive method based on library data intended to refer to conditions and restrictions of information freedom in international law while explaining concepts, sources and fundamentals of information freedom and mention its legal challenges and finally present suggestion for improving right of access to information in law of different countries in the world by classifying legality rules of information freedom restrictions to logical rules , rules of legal system and rules of human rights .

A Novel Approach for Multidimensional Quantitative Association Rule Mining
R. Sridevi, E. Ramaraj and N. Venkatesan
In data mining, the frequent patterns from single dimensional database and transactional databases are studied widely. Most of the previous works adopted the Apriori like approach which included repeated candidate generation and scan process. Moreover candidate generation is costly, especially for large number of patterns. In this paper, a new approach is proposed for the conversion of single dimensional database into multidimensional quantitative dataset for rule generation. The database is initially transformed into quantitative database in order to reduce the memory and increase the computational speed. The individual items are clustered with respect to category which is sufficient to satisfy all the constraints specified in problem domain to generate the rules. The objective is to generate more number of interesting rules that satisfy minimum confidence threshold (min_conf).
