This study evaluates the incorporation of alpha-linolenic acid （LNA, 18：3n-3） through the golden flaxseed in snacks＇ formulations with and without seasoning. Snacks with different formulations presented significant differences （P 〈 0.05） in their proximate composition, mainly for total lipids and moisture content. regarding the fatty acids profile, six different fatty acids were found： 16：0, 18：0, 18：1n-9, 18：1n-7, 18：2n-6 （LA） and 18：3n-3. The majority fatty acid was 18：2n-6 （LA） due to the predominance of corn in the products formulation. The incorporation of 18：3n-3 was observed, and this fatty acid was not affected by the extrusion temperature during the processing or the storage time. The results of sensory evaluation indicated that the product developed with addition of golden flaxseed had mild acceptance among the panelists. Thus, it was concluded that the addition of flaxseed is feasible for the nutritional enrichment of corn snacks.

The often-used phrase ‘the uplift of the Tibetan Plateau’ implies a flat-surfaced Tibet rose as a coherent entity, and that uplift was driven entirely by the collision and northward movement of India. Here, we argue that these are misconceptions derived in large part from simplistic geodynamic and climate modeling, as well as proxy misinterpretation. The growth of Tibet was a complex process involving mostly Mesozoic collisions of several Gondwanan terranes with Asia, thickening the crust and generating complex relief before the arrival of India. In this review, Earth system modeling, paleoaltimetry proxies and fossil finds contribute to a new synthetic view of the topographic evolution of Tibet. A notable feature overlooked in previous models of plateau formation was the persistence through much of the Cenozoic of a wide east–west orientated deep central valley, and the formation of a plateau occurred only in the late Neogene through compression and internal sedimentation.

Technological advancements are strongly required to fulfill the demands of new accelerator devices with the highest accelerating gradients and operation reliability for the future colliders. To this purpose an extensive r^zD regarding molybdenum coatings on copper is in progress. In this contribution we describe chemical composition, deposition quality and resistivity properties of different molybdenum coatings obtained via sputtering. The deposited films are thick metallic disorder layers with different resistivity values above and below the molibdenum dioxide reference value. Chemical and electrical properties of these sputtered coatings have been characterized by rutherford backscattering, XANES and photoemission spectroscopy. We will also consider multiple cells standing wave section coated by a molybdenum layer designed to improve the performance of X-Band accelerating systems.

In this paper,we consider the implementation of the “cloud" computing strategy to study data sets associated to the atmospheric exploration of the planet venus. More concretely,the venus Monitoring Camera (vMC) onboard venus Express orbiter provided the largest and the longest so far set of ultraviolet (Uv),visible and near-Ir images for investigation of the atmospheric circulation. To our best knowledge,this is the first time where the analysis of data from missions to venus is integrated in the context of the "cloud" computing. The followed path and protocols can be extended to more general cases of space data analysis,and to the general framework of the big data analysis.

Nitro MAC（French acronym for continuous atmospheric measurements of nitrogenous compounds） is an instrument which has been developed for the semi-continuous measurement of atmospheric nitrous acid（HONO）. This instrument relies on wet chemical sampling and detection using high performance liquid chromatography（HPLC）-visible absorption at540 nm. Sampling proceeds by dissolution of gaseous HONO in a phosphate buffer solution followed by derivatization with sulfanilamide/N-（1-naphthyl）-ethylenediamine. The performance of this instrument was found to be as follows： a detection limit of around 3 ppt with measurement uncertainty of 10% over an analysis time of 10 min. Intercomparison was made between the instrument and a long-path absorption photometer（LOPAP） during two experiments in different environments. First, air was sampled in a smog chamber with concentrations up to 18 ppb of nitrous acid. Nitro MAC and LOPAP measurements showed very good agreement. Then, in a second experiment, ambient air with HONO concentrations below250 ppt was sampled. While Nitro MAC showed its capability of measuring HONO in moderate and highly polluted environments, the intercomparison results in ambient air highlighted that corrections must be made for minor interferences when low concentrations are measured.

Four sites were selected in a salt marsh in the Bahia Blanca Estuary （Argentina）：（1） low marsh （flooded by the tide twice daily） vegetated by S. alterniflora; （2） non-vegetated low marsh; （3） high marsh （flooded only in spring tides） vegetated by S. alterniflora; （4） non-vegetated high marsh. The pH and Eh were measured in sediments, while dissolved nutrients （ammonium, nitrate, nitrite and phosphate） and particulate organic matter （POM） were determined in pore water, pH （6.2-8.7） was only affected by vegetation in low areas. Eh （from -300 to 250 mv） was lower at low sites than at high ones; in the latter, the values were higher in the non-vegetated sediments. The POM concentration was greater in the high marsh than in the low marsh, with no effect of vegetation. Ammonium was the most abundant nitrogen nutrient species in pore water, except in the non-vegetated high marsh where nitrate concentration was higher. All nitrogen nutrients were affected by both flooding and vegetation. Phosphate was always present in pore water at all sites throughout the year and its concentration varied within narrow limits, with no effect of flooding and greater values always at non-vegetated sites. Our results showed that the variability of the pore water composition within the marsh is greater than the temporal variation, meaning that both tidal flooding and vegetation are important in the dynamics of nutrients and organic matter in the sediment pore water.

Orbital debris from over 50 years of human activity in space are threatening the operations of existing and future satellites and the sustainability of high-value satellite orbits. This technical memorandum calls for the development of a cadastre that depicts the vulnerability of critical satellite orbits to accumulating orbital debris. A space infrastructure vulnerability cadastre could serve as a governance tool for use by developers and operators of critical space infrastructures to better communicate the current and future vulnerability of high-value orbits to the accumulation of orbital debris. These high-value orbits are susceptible to 'loss' for decades or centuries if generation of orbital debris continues unabated. The concept of environmental critical loads is applied to heavily used orbits as a way to indicate acceptable debris density for satellite operations, and when debris density/risk thresholds approach unacceptable levels that reduce the probability of sustaining spacecraft operations in those orbits.
