During processing of cereal-based food products, starch undergoes dramatic changes. The objective of this work was to evaluate the impact of food processing on the starch digestibility profile of cereal-based foods using advanced imaging techniques, and to determine the effect of preserving starch in its native, slowly digestible form on its in vivo metabolic fate. Four different food products using different processing technologies were evaluated: extruded products, rusks, soft-baked cakes, and rotary-molded biscuits. Imaging techniques (X-ray diffraction, micro-X-ray microtomography, and electronic microscopy) were used to investigate changes in slowly digestible starch (SDS) structure that occurred during these different food processing technologies. For in vivo evaluation, International Standards for glycemic index (GI) methodology were applied on 12 healthy subjects. Rotary molding preserved starch in its intact form and resulted in the highest SDS content (28 g/100 g) and a significantly lower glycemic and insulinemic response, while the three other technologies resulted in SDS contents below 3 g/100 g. These low SDS values were due to greater disruption of the starch structure, which translated to a shift from a crystalline structure to an amorphous one. Modulation of postprandial glycemia, through starch digestibility modulation, is a meaningful target for the prevention of metabolic diseases.

An HFES Task Force is considering if, when, and which, HFES research publications should require the citation of relevant standards, policies, and practices to help translate research into practice. To support the Task Force activities, papers and reports are being written about how to find relevant standards produced by various organizations (e.g., the International Standards Organization, ISO) and the content of those standards. This paper describes the human-computer interaction standards being produced by ISO/IEC Joint Technical Committee 1 (Information Technology). Subcommittees 7 (Software and Systems Engineering) and 35 (User Interfaces), and Technical Committee 159, Subcommittee 4 (Ergonomics of Human-System Interaction), in particular, the contents of the ISO 9241 series and the ISO 2506x series. Also included are instructions on how to find standards using the ISO Browsing Tool and Technical Committee listings, and references to other materials on finding standards and standards-related teaching materials.

Purpose: It was intended to measure the sound intensity of children's sound books and to compare them with the standards of Korea and the International Standards Organization (ISO).Methods: The loudness of 15 children’s sound books was measured at a distance of 25 cm (child’s arm length), and 2.5 cm length of external auditory canal. Measurements taken three times with each book were performed, and the overall sound intensity of the sound books and the sound intensity of each button were measured and compared.Results: Compared with the Korean standard, all the buttons of all books exceeded the standard for the sound volume of the children’s book measured at a distance of 2.5 cm. When comparing the maximum sound intensity measured at a distance of 25 cm with 85 LAmax, a total of 168 buttons of these, 25 (14.88%) were recorded as exceeding the maximum loudness. According to the standards of the ISO, all buttons in all books were below the standard 85 LAeq.Conclusion: Several children’s books are loud enough to cause noise-induced hearing loss, especially when they are placed close to the ear. Strict standards for sound children’s books are required, and it is important to put a warning on the cover of the book. It is expected that the sound intensity of the children’s sound book presented in this study can be referenced when referring to the loudness during hearing rehabilitation in children.

One of the major factors contributing to a healthy diet, proper selection of food consumers is the labeling of food products. In order to improve the requirements to labeling offood products in the Russian Federation and the Eurasian Economic Union and their harmonization with international standards and requirements of the European Union in the Technical regulations of the Customs Union "Food products are part of its labeling" (TR CU 022/2011) it should be amended as follows: 1. The list of indices of the nutritional value offood products referred to in their labeling, should be expanded by next positions: the amount of saturated fatty acids and trans fatty acids; carbohydrates, including mono- and disaccharides and the amount of added sugar; polyols; dietary fiber; added sodium chloride (salt). 2. To carry out the calculation of daily requirements of essential nutrients based on the human consumption of 2000 kcal per day, instead of 2500 kcal. 3. When setting the nutritional value offood products to envisage the application of the "color codes" indicating normal level of consumption by green, permissible - yellow, dangerously - in red. 4. In the text of the regulations Appendix, regulating the use in label offood to include information about the expected positive effects on the human body of the incoming (s) of the food product (s) ingredient (s) in case of systematic use of such a product in food rations.

In 1982, the American Society for Testing and Materials (ASTM) adopted consensus standard direct-normal and global-tilted solar terrestrial spectra (ASTM E891/E892). These standard spectra were intended to evaluate photovoltaic (PV) device performance and other solar-related applications. The International Standards Organization (ISO) and International Electrotechnical Commission (IEC) adopted these spectra as spectral standards ISO 9845-1 and IEC 60904-3. Additional information and more accurately representative spectra are needed by today’s PV community. Modern terrestrial spectral radiation models, knowledge of atmospheric physics, and measured radiometric quantities are applied to develop new reference spectra for consideration by ASTM.

The study will focus on technological components of the Indian Aadhaar program which tries to give every resident of the country a digital ID. The paper provides the architectural and implementation features of the program. Aadhaar program is only 40% implemented to date as mandated by the Government of India. Aadhaar is mostly based on Free Open Source Software (FOSS) and its processes are International Standards Organization (ISO) compliant. The paper would do a critical analysis of the architectures of the ID programs.

Abstract Ultrasound and microwave techniques were used to extract tobacco alkaloids, and response surface methodology was used to optimize extraction conditions. Ultrasonic technique factors were temperature, 30–85°C; time, 3–45 min; solvent volume, 8–80 mL. Microwave extraction factors were pressure, 15–75 psi; time, 3–40 min; power, 30–90% of the maximum magnetron power of 650 W. Soxhlet and solvent AOAC-modified extraction methods were also applied after some improvements. Nicotine, nornicotine, anabasine, and anatabine were quantified by gas chromatography. A steam distillation International Standards Organization method for total alkaloid evaluation was used as reference. The results obtained by the different methods were compared using a least squares deviation test. The ultrasonic and the proposed modified-AOAC extraction method were the more convenient with regard to practicability and precision. The relative deviations (n = 5) were as follows: For the ultrasonic method in low-level alkaloid tobaccos, 0.7% nicotine and 1.4–14% minor alkaloids; in high-level alkaloid tobaccos, 2.4% nicotine and 4.5–5.1% minor alkaloids. For the modified AOAC method in low-level alkaloid tobaccos, 0.9% nicotine and 2.4–11.6% minor alkaloids; and in high-level alkaloid tobaccos, 1.7% nicotine and 2.0–2.4% minor alkaloids.
