Objective: Combating iron deficiency in toddlers with iron-fortified food has proved difficult in countries with phytate-rich diets. For this purpose, a new haem iron preparation was developed. The study compared changes in iron status after administration of refried beans with beans fortified with a haem iron preparation or ferrous sulphate (FeSO 4 ). Design: In a masked, stratified-randomised intervention trial, children received five 156-g cans of refried black beans per week for 10 consecutive weeks. The beans-only (control), FeSO 4 and haem iron groups were offered a cumulative dose of 155 mg, 1625 mg and 1700 mg of iron from the bean intervention, respectively. Haemoglobin (Hb) and ferritin concentrations were determined at baseline and after 5 and 10 weeks. Compliance was examined weekly.
We determine an upper bound for a possible right-handed b→c quark current admixture in semilep-tonicB → Xc −ν decays from a simulateous fit to moments of the lepton-enery and hadronic-mass distribution measured as a function of the lower limit on the lepton energy, using data measured by the BABAR detector. The right-handed admixture is parametrized by a new parameter cR as coefficient of computed moments with right-handed quark current. For the standard model part we use the prediction of the heavy-quark expansion (HQE) up to order 1/m 3 b and perturbative corrections and for the right-handed contribution only up to order 1/m 2 b and perturbative corrections. We find c R = 0.05 +0.33 −0.50 in agreement with the standard-model prediction of zero. Additionally, we give a contraint on a possible right-handed admixture from exclusive decays, which is with a value of c R = 0.01±0.03 more restrictive than our value from the inclusive fit. The difference in |V cb | between the inclusive and exclusive extraction is only slightly reduced when allowing for a right-handed admixture in the range of c R = 0.01±0.03.where J µ l =ē γ µ P − ν e is the usual leptonic current and J h,µ is the generalized hadronic b→c current which is arXiv:1003.4022v1 [hep-ph]
Additive manufacturing is a novel manufacturing paradigm which has numerous potential applications in industry and research. PolyJet technology allows printing of extremely complex geometrical structures with high precision and smooth surface. New engineering polymers with diverse characteristics should be developed to expand PolyJet applications. Bismaleimides (BMIs) are very attractive polymers due to their excellent thermal, mechanical, and chemical stability, and their good dielectric properties. However, BMIs are currently not available as inks for PolyJet technology. Low‐viscosity aliphatic BMIs are used to develop a novel UV‐curable ink. The UV reactivity and ink viscosity are optimized by addition of an environmentally friendly diluent and a mixture of photoinitiators. Optimization of the jetting and printing conditions allows for the first ever production of 3D thermosetting BMI objects by PolyJet technology. Thermal post curing is used to enhance mechanical properties and thermal stability of the printed material. It is found to have a thermal decomposition temperature, T5%, of about 400 °C, low dielectric constant, high dielectric strength, and low moisture absorption. The resulting properties of the printed BMI material open a wide range of potential applications in fields such as robotics, electronics, automotive, aerospace, and space technology.
