Synchrotron-based X-ray fluorescence microscopy (XFM) using hard X-rays focused into sub-micron spots is a powerful technique for elemental quantification and mapping, as well as microspectroscopic measurements such as μ-XANES (X-ray absorption near edge structure). https://en.wikipedia.org/wiki/Timberland We have used XFM to image and simultaneously quantify the transuranic element plutonium at the L(3) or L(2)-edge as well as Th and lighter biologically essential elements in individual rat pheochromocytoma (PC12) cells after exposure to the long-lived plutonium isotope (242)Pu. timberlandirelandboots Elemental maps demonstrate that plutonium localizes principally in the cytoplasm of the cells and avoids the cell nucleus, which is marked by the highest concentrations of phosphorus and zinc, under the conditions of our experiments. http://www.timberlandirelandboots.net The minimum… detection limit under typical acquisition conditions with an incident X-ray energy of 18 keV for an average 202 μm(2) cell is 1.4 fg Pu or 2.9×10(-20) moles Pu μm(-2), which is similar to the detection limit of K-edge XFM of transition metals at 10 keV. Copper electron microscopy grids were used to avoid interference from gold X-ray emissions,Timberland ireland careers but traces of strontium present in naturally occurring calcium can still interfere with plutonium detection using its L(α) X-ray emission.
From the nutritional point of view, data on dietary fiber content, tannin and in vitro protein digestibility of processed millet is of importance, because millets are never eaten raw. http://www.timberlandirelandboots.net Effects of commonly used traditional methods on dietary fiber, tannin content and %IVPD of two locally available pearl millet varieties (Kalukombu and Maharashtra Rabi Bajra) were investigated. timberlandirelandboots The millet was subjected to various processing methods like milling (whole flour, semi refined flour and bran rich fraction) roasting, boiling, pressure cooking & germination respectively. Processing had little effect on the total dietary fiber (TDF) content in both varieties; however the bran rich fraction showed highest TDF content of around 29%. Timberland ireland discount code Tannins effectively lowered upon boiling and pressure cooking… respectively, but significantly increased (P ≥ 0.05) upon germination. Although the % IVPD of the millet (45.5 – 49.3 g/100g) was low, it significantly increased upon milling (bran rich fraction), roasting and germination respectively.
Abstract:Health‐promoting messages can be framed in terms of the gains that are associated with healthy behaviour (gain frame) or the losses that are associated with unhealthy behaviour (loss frame). timberlandirelandboots In the present research, we examined the role of positive and negative affect in the persuasive effects of gain‐ and loss‐framed health‐promoting information. http://www.timberlandirelandboots.net Experiment 1 (N = 98) showed that gain‐framed information resulted in higher levels of information acceptance than loss‐framed information and that this effect was mediated by positive affect.Timberland ireland phone number The results of Experiment 2 (N = 129) showed that gain‐framed information resulted in higher levels of information acceptance and attitude, an effect that was again mediated by positive affect. In addition, loss‐framed information resulted in more… negative affect than gain‐framed information and negative affect increased participants’ intention to engage in the healthy behaviour. These results suggest that affect may be of great importance in the persuasion process and may be particularly helpful to explain the underlying mechanisms of message framing effects. The findings also suggest that gain‐ and loss‐framed messages offer distinct pathways to persuasion. Copyright © 2009 John Wiley & Sons, Ltd.
