    Cloud storage technology is attracting more attention due to the increasing implementation of technology in everyday life. The present study aims to assess Iranian iCloud users' richness of information security awareness at the three levels of knowledge, attitude, and behavior, based on six aspects required for adhering to information security policies. Accordingly, in this study, the self-reported data of 384 Iranian users of Apple products (IUAP) were investigated using a questionnaire designed by a researcher. Then, the data were analyzed using Microsoft Excel software. This research showed that the average information security awareness of IUAP is 3.22 out of 5, a slightly higher than average score using a quantitative approach and descriptive statistics,. Almost three-quarters of them use iCloud, mainly because of its easy access to information. It also assesses various aspects and examples of information security awareness and behaviors that indicate compliance with information security policies. Finally, the general knowledge of Iranian iCloud users about the components of information security awareness is estimated to be 73.83, which is relatively low and unsatisfactory, showing that more attention and training are needed. Moreover, this study prioritizes different components of information security awareness

    Determination of vitamins B1 and B6 in infant formula and food supplement samples using magnetic layered double hydroxide nanoadsorbent before liquid chromatography-tandem mass spectrometry

    A magnetic Mg/Fe layered double hydroxide (magnetic LDH) nanocomposite was successfully prepared and used as a suitable adsorbent to simultaneously extract vitamins B1 and B6 from complex infant formula and food supplements. The important parameters affecting the extraction were optimized and the final parameters are as follows; the amount of adsorbent (20 mg), extraction time (6 min), elution time (8 min), and elution solvent ethanol in 750 µL. As-prepared nanoadsorbent was successfully in magnetic solid phase extraction set-up with no hazardous solvents and extraction performed in 6 min. The structure of nanoadsorbnet is lamellar, providing a wide surface to extract the analytes. The quantification of the analytes was accomplished using the liquid chromatography-tandem mass (LC/MS-MS) technique. Under optimum extraction conditions, the linearity ranged from 4 to 1000 ng/mL (vitamin B1) and 20 to 1000 ng/mL (vitamin B6), and the correlation of coefficients (R2) was obtained better than 0.99. The intra-day (n = 3) and inter-day precisions (n = 3 working days) calculated in the form of percent relative standard deviations (%RSDs) were obtained below 10.20%. The proposed method was successfully practiced for analyzing vitamins B1 and B6 in several brands of infant formulas and food supplements.</p
