There are many factors affecting the tolerance Values of instrumentally measured Color differences, including variety of industries, type of products to be matched with the original samples, the need of customers, etc. Regarding the insufficiency of various Color difference formulae to deal with the acceptability of Color matching of reproduced samples with the target, some researchers tried to present an instrumental Color tolerance limit in accordance with the results of visual assessment experiments. Considering the specific Colorimetric attributes of achromatic samples (with low lightness and chroma Values), it was tried to set an instrumental tolerance limit based on the measured and visually perceived Color differences between 20 filament black yarns and the reference one. The results showed that determining the Color tolerance value based on various Color difference formulae, i. e. )Ea*b*, CIE94, CIE2000 and CMC (2: 1), results in different instrumental wrong decisions, while the )E*ab Color difference equation with the Color tolerance value of 0. 5 for filament black yarns showed the minimum number of wrong decisions.

A condition that must be satisfied for digital printers in a Color management system is converting device-dependent Color Values into device-independent Color Values by a transfer model of high-quality performance. Usually, each transfer model is initially trained with some specified samples as a training set before being tested. In the present study, Color charts with different quantities of Color patches in an RGB space were selected and printed as training groups. The spectral reflectances of all samples in printed Color charts were measured and converted to an XYZ Color space under a standard observer/illuminant combination. Using a matrix method, the RGB to XYZ transformation matrices were obtained with the algebraic operation of different degrees of polynomials and the least-square errors for the training groups. Similar operations were also performed for the well-known ProfileMaker software, which is based on a look-up table method. Finally, the statistical Values of Color difference (DE2000) were calculated between the actual XYZ from the printed Color charts, the predicted XYZ from the matrix method, and those predicted from the ProfileMaker software. The ProfileMaker software showed a significantly lower Color difference near the perception threshold for the specified training samples.

Nowadays, auxiliaries are playing a very important role in improving textile dyeing and printing conditions. In the present study, cotton/polyester fabric was padded with beta-cyclodetrin (b-CD) and after printing with disperse-reactive dyes, samples were treated with TiO2 nanoparticle to improve their self-cleaning properties. The effect of b-CD on properties of printed fabric and scanning electron microscope surface image, their self-cleaning and antimicrobial properties were studied. According to the results, increasing concentration of b-CD could reduce Color strength (K/S) of the samples and their water absorption time whilst water spreading area and value of the retained water were increased. b-CD showed a very limited effect on improving antimicrobial activity of goods.

The Qur'an contains religious Values ​​for the advancement of man to happiness. The claim is that Quranic teachings are the basis of religious Values; By choosing it better, the method of proving religious beliefs can be extracted. This research tries to extract the method of proving religious beliefs with a business approach and by using artistic forms with a descriptive and analytical method and with a better selection of Quranic teachings. Based on the verses, the process was defined as the introduction to the institutionalization of religious Values ​​in the businessman 1- Gaining self-knowledge (knowing the talents, capacities, existential dimensions and position of man in the universe); 2- Gaining monotheistic insight (knowing the origin and your relationship with the Creator); 3- Reciprocity is (knowing the destination and drawing the path of happiness in the universe). After the realization of these three stages, the beliefs must be proven through rational and scientific reasoning and penetrate, in this case, the acceptance of good qualities in the businessman will be facilitated.

In this study, changes in Color index (CI), refractive index (RI) and viscosity in a range of commonly frying oils during frying process were investigated, and their performance compared to the carbonyl value (CV) as a reference method in monitoring of the quality of frying oils was evaluated. It was observed that the CI of the frying oils linearly increased with frying time. The initial CI of frying oils was 0.36±0.15 on average, and it reached 1.73±0.24 after 48 h of the frying process. The CI had a linear relationship with the CV with a high determination coefficient, R2=0.97, during the frying process. Assuming that the limit of acceptance for the CV is 43.50mmol/g, this roughly corresponded to 1.12 for the CI. As the oxidation accelerated by heat proceeded, the value of RI linearly increased. On average, the RI of the frying oils changed from 1.468313±0.00051 (0 h) to 1.469671±0.00032 (48 h). The RI of the frying oils showed a high correlation with the CV (R2=0.94). Assuming that the maximum level permitted for the CV is 43.50 µmol/g, the RI of a frying oil should be£1.469075. Viscosity of the frying oils at 30°C increased with time and changed from 45.11±13.84 mPa s (0 h) to 75.03±12.47mPa s (48 h) on average. There was a strong correlation (R2=0.96) between the viscosity and CV of the frying oils. If 43.50 µmol/g of CV is the maximum level permitted in frying oils, viscosity of a frying oil should be£74.78mPa s at 30oC.

Introduction: Social responsibility from an ethical point of view includes the obligations and duties of natural and legal persons towards society and the environment. The moral behavior of people, like understanding of social responsibility, depends on their liberal ideology, beliefs and human Values. Therefore, the aim of the current research is to study the relationship between liberalism and human Values with the moral understanding of social responsibility. Material & Methods: The research method is applied in terms of purpose and descriptive-correlational survey. The statistical population includes the financial managers of the companies admitted to the stock exchange, and the questionnaire was randomly distributed among them and 110 questionnaires were received. The sampling method is random. The research tool is a questionnaire and multivariate regression using SPSS software was used to analyze the data. Results: The research results show that human Values based on public interest have a significant and positive relationship with the moral understanding of social responsibility. But the thinking of liberalism does not have a meaningful relationship with the moral understanding of social responsibility. Conclusion: Based on the findings of this research, human Values based on public interest can be considered as a tool to strengthen the moral behavior of company managers regarding corporate social responsibility. Also, improving the thinking of liberalism in managers can strengthen their social responsibility. In this case, the policy makers of Stock Exchange can direct the managers of the listed companies to comply more with the social responsibility of the company, through teaching human Values and strengthening those Values, as well as monitoring the implementation of ethical regulations

Application of additives is one of the proper solutions in quality enhancement in bakery products such as gluten matrix promotion, softness and unity of the texture and delay in staling which are effectives on shelf life and marketability of the bread. So the aim of this study was to investigate the synergistic effect of Datem, SSL and E471 as an emulsifier in level of 0.2% and 0.5% humectants such as polypropylene, glycerin and polysorbat 60 in compare to the control (without additives) on quantitative and qualitative properties of semi bulk Barbary bread. Image processing and Image J software were used for evaluation porosity and Color Values of samples. The results showed that the addition of a combination of emulsifiers and Humectants improved the specific volume, porosity, overall acceptability score and Color Values of samples in compare to the control. while the firmness of bread was reduced significantly (p<0.05). The results indicate SSL had the better performance that E471 and polypropylene was more effective in compare to the glycerin and polysorbat 60. Finally, the results indicate that the synergistic effect of 0.2% Datem and SSL with 0.5% polypropylene as humectants was more than others. So that leads to the excellent and marketable product.
