Atmospheric showers are initiated when primary cosmic rays hit the Earth’s atmosphere. Secondary mesons produced in this collision, mostly pions and kaons, decay and give rise to electron and muon neutrino and anti-neutrinos fluxes [1]. In the past Fréjus and NUSEX [2] reported a R-value (R = (μ/e)data/(μ/e)MC) consistent with one, therefore other detectors like Kamiokande, IMB and Soudan-2 [3]...

The purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. Recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. One such development is the active food packag...

the main task of this work is related with the design of a class of siso robust control law for theregulation of substrate concentration (cdo) of an industrial activated sludge wastewater plant. the controldesign is related with an uncertainty estimator (reduced order observer) based active control. departing from the tracking error between the desired and the current substrate concentrations t...

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...

this article is aimed to explain sociologically active aging with emphasizing the social capital in esfahan. the present research is a survey and in terms of purpose is a practical type of cross-sectional study. the population is all elderly over 60 years in esfahan in 2015. the sample size is selected by using cochran formula to 384 subjects and a quota sampling method is done by focusing the ...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

the alluvial fan of shahdaad in derakhtangaan river is one of the biggest alluvial fans in a dry area in northeastern kerman. this alluvial fan has been formed due to different material erosions in the drainage basin of derakhtangaan river and lying of these materials in the extreme part of this basin called dasht-e-lut (the plain of lut). the region which has been studied in this research is o...
