Recent experience with fortification of foods and beverages with iron for the control of iron-deficiency anemia in Brazilian children

Iron-deficiency-anemia affects 30% of the world population. Women of reproductive age and children are the most affected. Iron supplementation in the form of tablets and syrups has not been successful in developing countries, and iron deficiency is still the most important deficiency related to malnutrition. Iron-deficiency anemia affects physical and cognitive development at an early age in children, often resulting in irreversible outcomes. Studies from the last two decades have shown that the prevalence of iron-deficiency anemia can be reduced given adequate investments and political will directed at iron fortification of foods and liquids. A successful low-cost iron-fortification program incorporates implementation and strategic use of communication for program inception where education is in the forefront. A review of the available reports from experience in Brazil with iron fortification of foods and liquids is presented.     

Physicochemical and Rheological Properties of Taro (Colocasia esculenta) Flour Affected by Cormels Weight and Method of Peeling

The present study investigated the effect of peeling and cormels weight on physicochemical and rheological properties of taro (Colocasia esculenta) flour. The cormels were divided by the weight into four classes: size?<?170 g, 170?<?size?<?214 g, 214 g?<?size?<?284 g, and size?>?284 g. Each one of these classes contains half of peeled and unpeeled cormels. The results showed a difference between the flour derived from different taro cormels weight in term of the physicochemical, morphological, and rheological properties. However, no difference was observed in terms of the thermal properties. The study revealed that taro flours are mainly made of dietary fibers. The granule size of the flour varied significantly within each different cormels weight in the same method of peeling and the mean flour diameters are around 204 μm. For both form of peeling, potassium was found to be the higher mineral and sodium was the lower one. Concerning phytate, the peeled samples have the lowest values of 5.76 and 4.79 mg/g dry matter, respectively, for cormels size?<?170 g and 170 g?<?size?<?214 g. Finally, we observed that peeling methods and weight of taro cormels have an influence on some physicochemical composition of flour and rheological properties of flours suspensions.

Experiments on high excitation density, quenching, and radiative kinetics in CsI:Tl scintillator

Information on quenching as a function of electron-hole density through the range of 10¹⁹ to 2×10²⁰ e-h/cm³ typically deposited towards the end of an electron track has been acquired using 0.5 ps pulses of 5.9 eV light to excite in the band-to-band or high-exciton region of CsI and CsI:Tl. A streak camera records partially quenched luminescence from self-trapped excitons (STE) and excited activators (Tl^+?). Both the Tl^+? and STE luminescence exhibit decreasing light yield versus excitation density N_max, but it is only the 302 nm STE luminescence that exhibits decay time quenching dependent on N_max. Fitting the STE decay time data to a model of dipole-dipole quenching yields the time-dependent bimolecular rate constant for quenching of STEs (and Tl^+? light yield) in CsI at room temperature: k₂(t)=2.4×10⁻¹⁵ cm³ s^−1/2 (t^−1/2).     

Social Media and Citizen Participation in “Official” and “Unofficial” Electoral Promotion: A Structural Analysis of the 2016 Bernie Sanders Digital Campaign

Drawing on interviews with leaders of the effort to promote the 2016 Bernie Sanders U.S. presidential candidacy on social media, this study contrasts the structure and content of various organizational networks to map the hybrid ecosystem of the contemporary digital campaign. While the “official” Sanders organization built applications to transform supporters into a tightly controlled distribution network for its social media messaging, this was complemented by “unofficial” grassroots networks that circulated more informal and culturally oriented appeals. The latter are classified according to the models of organizationally enabled and self-organized connective action in digital social movements, with structural differences in oversight and moderation that suggest varying levels of creative autonomy for citizens and reputational risk for the associated campaigns.     

Making Sense: The MIX House

In an effort to challenge the dominance of vision over the other senses in architectural experience, Joel Sanders and Karen Van Lengen infuse a speculative domestic environment with digital audio technology. Their design capitalises on the augmentation of aural–visual boundaries via technological interventions, ultimately recasting the house from a private and insulated environment to that of a hybridised interactive site.

便于功率因数校正的控制器NCP1601

临界导电模式(BCM)目前是满足中低功率应用中功率因数校正(PFC)稳压的最常用方案.但是,这种解决方案的开关频率的方差很大,使得在噪声敏感和大功率范围应用中实现BCM电路很困难.为了克服这个缺点,安森美半导体开发了一个创新的功率因数控制器-NCP1601,可以在固定频率和不连续导电模式(DCM)中工作.为了达到整功率因数,电路根据在先前开关周期中测得的死区时间长度调制功率开关导电时间.本文讲述NCP1601方案和功能.
