Abstract

Background: Among different aforementioned methods, adsorption is one of efficient methods for the removal of dyes from textile wastewater. Activated carbon because of the high cost of production and recovery in developing countries cannot use as a desirable option. Therefore, this investigation has been conducted for preparation of activated carbon from walnut wastes as a natural adsorbent for the removal of Reactive Red 2(RR2) form aqueous solution. and for optimizing variables; initial concentration of dye, and absorbent dosage Furthermore, the study of isotherm models as indicator has been conducted. Materials and methods: Walnut shell was collected and prepared in chemical – physical method and steam activation method was used. (RR2) was used for synthetic wastewater preparation.The adsorption study of RR2 was conducted in glassy column with diameter of 1 cm and 25 cm high, that filled by different dosage of carbon (0.5, 1, 1.5 and 2).All experiments were performed six times with 144 tests. Excel software was used to analyze the results. Results: The results showed that adsorption of Reactive Red 2 on prepared activated charcoal steam has direct relationship with increase of color concentrations and inversely associated with the increased absorbent material. Match the results with the adsorption isotherm showed that data has better match with the Langmuir adsorption isotherm with a R2=0.92.

Abstract

This factorial experiment within a randomized complete block design with 4 replications was conducted to examine the effect of foliar application of Iron, zinc, and selenium on nutrient uptake and yield of alfalfa under rainfed conditions in Aligoudarz, Iran. The treatments of the experiment included the iron at 3 levels: the control (non-use of iron), iron sulfate at the concentration of 3/1000, and completely liquid iron 5%; zinc at 3 levels: the control (non-use of zinc), zinc sulfate at the concentration of 3/1000, and completely liquid zinc 5%; and selenium at 2 levels: the control (non-use of selenium) and sodium selenite at the concentration of 20 g/ha. The results of data variance analysis showed that the effect of foliar spray of iron, zinc, and selenium was significant on all properties at significance level of 1%. Maximum yield of alfalfa was 3506.2 kg/ha obtaining from the treatment with iron sulfate at a concentration of 3/1000 + zinc sulfate at a concentration of 3/1000 + 20 g of selenium per hectare, which showed an increase of 34% as that in the control treatment. Moreover, results showed that the foliar spray considerably increased the uptake of iron, zinc, and selenium in plants.

Abstract

Today the Internet has brought huge impacts on all aspects of marketing and management, and innovation in these technologies is to the extent that they must have great flexibility to deal with those companies and organizations so that they can take advantage of the unique capabilities of the new technology. This study was performed to evaluate the Internet’s impact on sports marketing and its internal dimensions. The research was a descriptive-analytic study. The study population consisted of the graduate students of sport management in Khorasan Razavi province (124 people who were used as the statistical sample using the census sampling method. The research instrument consisted of a standard questionnaire designed by Qazi Saeedi et al. about the impact of the Internet on marketing (2007), which its validity and reliability was confirmed by Cronbach's alpha (0.89). The descriptive and inferential statistics (independent-samples t-test, Mann-Whitney test and Friedman test) was used for data analysis. Our findings indicate the role of the Internet on sports marketing and its dimensions. The results showed that the Internet has the most important role in the dimensions of “the changes in the conceptualization of sports marketing activities” and the least role in the dimension of “the creation of new values in sports marketing”. However, no difference was observed between the perspectives of men and women participating in the study. Considering the role of the Internet in the promotion of sports marketing, sports organizations have nowadays to consider the importance of the Internet and its use in the strategic planning process of marketing and its dimensions (including market research, pricing).
