Background: The municipal waste landfill sites have high a potential of contaminating the environment and having effects of the human health due to waste degradation, production of leachate, carbon dioxide and methane gases. The present study aims to evaluate the location of the solid waste landfill using GIS and based on the Oleckno index. Assessment parameters included average annual rainfall, soil type and ground water beneath and adjacent to the landfill site.Methods: This study was based on field- and library-based data collection, and surveys of relevant data. Then data were registered into the GIS environment and overlaying layers analysis method was used.Findings: In 2010 the total rainfall in the landfill region was less than 150 mm/year. The soil material was clay loam, and the average distance from the floor of the landfill to the groundwater level was 3-9 meters. As calculated results showed that, the Oleckno Index score in the study area was 40. This means that the conditions were good and there was low groundwater pollution potential.Conclusion: The new landfill site of the city and suburb of Isfahan had a good Oleckno index and the possibility of contamination of groundwater by leachate production based on this index was also low.

This study was conducted during summer and winter of 2018- 2019 in the agricultural research field of Shahid Chamran University. Experimental design was split- plot based on RCBD with three replications. The main plot was the type of agricultural system in three levels including conventional (Conv), organic (Org) and sustainable (Sust) (integrated between Conv and Org) and sup- plot was the type of pre- cultivated crop in sequence with wheat including cultivation of mung bean (M- W), corn (C- W), sesame (S- W) and fallow (F- W). Yield quantity (yield and its component) and quality (grain protein), an estimate of photosynthesis matter transfer index of wheat and soil organic carbon (SOC) after one double-cropping were measured. The result showed that the highest (545.04 g/m2) and the lowest (409.28 g/m2) seed yields were obtained in Conv and Org respectively. In contract, with the changing type of system from Conv to Org, grain protein was increased significantly (from 8.3 to 9.6 %). In addition, the highest (535.47 g/m2) yield of wheat was obtained from M- W double cropping. On the other hands the highest remobilization and current photosynthesis matter were obtained in the organic agricultural system with M- W and conventional with M- W double cropping. The situation of SOC showed that the highest (33.18 mg/g) SOC was obtained in the organic agricultural system with C- W double cropping. The reason for improving SOC in the organic and sustainable agricultural system was application of organic matter (compost and vermicompost) and crop residue management. Totally, from the crop ecology point of view, sustainable agricultural method with a sequence of M- W was the most desirable system.

Introduction: Use of Information system is an index of development in healthcare. An Information system captures healthcare data and processes it to create useful Information. Nursing leaders are interested in developing computerized records. In Iran, there are some computerized Systems for documentation of nursing data; some functions of these Systems are: bed management, Lab, X-ray and drug requests, vital signs, nursing report, Caredex and ward management. This research was done with the objective of assessing nursing Information Systems (NIS) in Iran.Methods: Current computer companies in Iran which have nursing modules (9 companies) were assessed in this cross sectional study in 2010. First, literature was reviewed and a valid and reliable questionnaire was developed. Then experts prioritized NIS needs. Finally, Iran’s NISs were assessed using the identified priorities.Results: Result showed that our NISs comply only 35.7% (95% CI: 29.99-41.41) of the identified priorities. None of the NISs comply nursing classification Systems’ needs.85.2% of financial reports’ needs (95% CI: 73.73-96.67) were complied in our NISs.Conclusion: The result showed that NISs in Iran are not very good. Using nursing data coding Systems, paying attention to bedside data capturing and active participation of nurses are recommended.

The globalization of computer Systems application, increasing the software and hardware capabilities and the possibility of matching Information transmission with human conceptual processes through Information visualization and their elements like color, shape, size, etc. makes Information visualization one of the important features in software designing.Information visualization consists of calculation and signal transmission of human conceivable numeral shape for understanding and discovering hidden relations between' data elements.The current paper tries to investigate the various aspects of Information visualization and their-techniques including Pan& Zoom, Multiple Windows, Map View Strategy, Focus + Context, Hyperbolic Browser, Cone- Trees, Intelligent Zoom, Magic Ler1sand Chops Approach.
