Real-Time Mining Control Cockpit: a framework for interactive 3D visualization and optimized decision making support

Real-Time Mining is a research and development project within the European Union\'s Horizon 2020 initiative and consists of a consortium of thirteen European partners from five countries. The overall aim of Real-Time-Mining is to develop a real-time framework to decrease environmental impact and increase resource efficiency in the European raw material extraction industry. The key concept of the research conducted is to promote a paradigm shift from discontinuous to a continuous process monitoring and quality management system in highly selective mining operations. The Real-Time Mining Control Cockpit is a framework for the visualization of online data acquired during the extraction at the mining face as well as during material handling and processing. The modules include the visualization of the deposit-model, 3D extraction planning, integrated data of the positioning-system as well as the visualization of sensor and machine performance data. Different tools will be developed for supporting operation control and optimized decision making based on real-time data from the centralized database. This will also integrate results from the updated resource model and optimized mine plan. The developed Real-Time Mining cockpit software will finally be integrated into a wider central control and monitoring station of the whole mine

Structural characterization of a-plane Zn1−xCdxO (0 < x <0.085) thin films grown by metal-organic vapor phase epitaxy.

Zn1−xCdxO(11math0) films have been grown on (01math2) sapphire (r–plane) substrates by metal-organic vapor phase epitaxy. A 800-nm-thick ZnO buffer, deposited prior to the alloy growth, helps to prevent the formation of pure CdO. A maximum uniform Cd incorporation of 8.5 at. % has been determined by Rutherford backscattering spectrometry. Higher Cd contents lead to the coexistence of Zn1−xCdxO alloys of different compositions within the same film. The near band-edge photoluminescence emission shifts gradually to lower energies as Cd is incorporated and reaches 2.93 eV for the highest Cd concentration (8.5 at. %). The lattice deformation, due to Cd incorporation, has been described using a new reference frame in which the lattice distortions are directly related to the a-plane surface structure. Cd introduction does not affect the c lattice parameter but expands the lattice along the two perpendicular directions, [11math0] and [math100], resulting in a quadratic volume [email protected] [email protected]

Effects of telmisartan and ramipril on adiponectin and blood pressure in patients with type 2 diabetes

&lt;b&gt;Background:&lt;/b&gt; Adiponectin is secreted by adipose tissue and may play a role in cardiovascular disease. We examined adiponectin levels in patients with type 2 diabetes who participated in the Telmisartan vs. Ramipril in Renal Endothelial Dysfunction (TRENDY) study. &lt;b&gt;Methods&lt;/b&gt; A total of 87 patients were assessed at baseline and following 9 weeks treatment with the angiotensin-receptor blocker telmisartan (final dose, 80 mg; n = 45) or the angiotensin-converting enzyme inhibitor ramipril (final dose, 10 mg; n = 42). Adiponectin levels were measured in plasma by radioimmunoassay. &lt;b&gt;Results:&lt;/b&gt; Adiponectin levels were inversely correlated with systolic (SBP; r = -0.240, P &#60; 0.05) and diastolic (DBP; r = -0.227, P &#60; 0.05) blood pressure at baseline and following treatment with telmisartan or ramipril (SBP: r = -0.228, P &#60; 0.05; DBP: r = -0.286, P &#60; 0.05). Changes in adiponectin levels were related to changes in SBP (r = -0.357, P &#60; 0.01) and DBP (r = -0.286, P &#60; 0.01). There was a significant increase in adiponectin levels in the telmisartan (0.68 (95% confidence interval (CI), 0.27 to 1.10) &lt;sup&gt;&#181;&lt;/sup&gt;g/ml, P &#60; 0.01) but not in the ramipril group (0.17 (95% CI, -0.56 to 0.90) &lt;sup&gt;&#181;&lt;/sup&gt;g/ml, P = 0.67). Blood pressure reduction in the telmisartan group (DeltaSBP: -13.5 (95% CI, -17.0 to -10.0) mm Hg; &#916;DBP: -7.6 (95% CI, -9.8 to -5.3) mm Hg, each P &#60; 0.001) was significantly (P less than or equal to 0.01 for SBP and P &#60; 0.01 for DBP) greater than in the ramipril group (&#916;SBP: -6.1 (95% CI, -6.2 to -2.0) mm Hg; &#916;DBP: -2.7 (95% CI, -5.0 to -0.5) mm Hg; P &#60; 0.01 and P &#60; 0.05, respectively). &lt;b&gt;Conclusion:&lt;/b&gt; Adiponectin is correlated with blood pressure in patients with type 2 diabetes. Whether increased adiponectin contributes to the blood pressure–lowering effect of telmisartan needs further study

Degradation Kinetics of Lignocellulolytic Enzymes in a Biogas Reactor Using Quantitative Mass Spectrometry

The supplementation of lignocellulose-degrading enzymes can be used to enhance the performance of biogas production in industrial biogas plants. Since the structural stability of these enzyme preparations is essential for efficient application, reliable methods for the assessment of enzyme stability are crucial. Here, a mass-spectrometric-based assay was established to monitor the structural stability of enzymes, i.e., the structural integrity of these proteins, in anaerobic digestion (AD). The analysis of extracts of Lentinula edodes revealed the rapid degradation of lignocellulose-degrading enzymes, with an approximate half-life of 1.5 h. The observed low structural stability of lignocellulose-degrading enzymes in AD corresponded with previous results obtained for biogas content. The established workflow can be easily adapted for the monitoring of other enzyme formulations and provides a platform for evaluating the effects of enzyme additions in AD, together with a characterization of the biochemical methane potential used in order to determine the biodegradability of organic substrates

Nocardia macrotermitis sp. nov. and Nocardia aurantia sp. nov., isolated from the gut of the fungus-growing termite Macrotermes natalensis

The taxonomic positions of two novel aerobic, Gram-stain-positive Actinobacteria, designated RB20$^{T}$ and RB56$^{T}$, were determined using a polyphasic approach. Both were isolated from the fungus-farming termite Macrotermes natalensis. Results of 16S rRNA gene sequence analysis revealed that both strains are members of the genus Nocardia with the closest phylogenetic neighbours Nocardia miyunensis JCM12860$^{T}$ (98.9 %) and Nocardia nova DSM44481$^{T}$ (98.5 %) for RB20$^{T}$ and Nocardia takedensis DSM 44801$^{T}$ (98.3 %), Nocardia pseudobrasiliensis DSM 44290$^{T}$ (98.3 %) and Nocardia rayongensis JCM 19832$^{T}$ (98.2 %) for RB56$^{T}$. Digital DNA–DNA hybridization (DDH) between RB20$^{T}$ and N. miyunensis JCM12860$^{T}$ and N. nova DSM 44481$^{T}$ resulted in similarity values of 33.9 and 22.0 %, respectively. DDH between RB56$^{T}$ and N. takedensis DSM44801$^{T}$ and N. pseudobrasiliensis DSM44290$^{T}$ showed similarity values of 20.7 and 22.3 %, respectively. In addition, wet-lab DDH between RB56$^{T}$ and N. rayongensis JCM19832$^{T}$ resulted in 10.2 % (14.5 %) similarity. Both strains showed morphological and chemotaxonomic features typical for the genus Nocardia , such as the presence of meso-diaminopimelic acid (A$_{2}$pm) within the cell wall, arabinose and galactose as major sugar components within whole cell-wall hydrolysates, the presence of mycolic acids and major phospholipids (diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol), and the predominant menaquinone MK-8 (H4, ω-cyclo). The main fatty acids for both strains were hexadecanoic acid (C$_{16 : 0}$), 10-methyloctadecanoic acid (10-methyl C$_{18 : 0}$) and cis-9-octadecenoic acid (C$_{18 : 1}$ ω9c). We propose two novel species within the genus Nocardia : Nocardia macrotermitis sp. nov. with the type strain RB20$^{T}$ (=VKM Ac-2841$^{T}$=NRRL B65541$^{T}$) and Nocardia aurantia sp. nov. with the type strain RB56$^{T}$ (=VKM Ac-2842$^{T}$=NRRL B65542$^{T}$)

Mobilization of putative high-proliferative-potential endothelial colony-forming cells during antihypertensive treatment in patients with essential hypertension

Recent studies have shown that in response to vascular damage or ischemia, bone marrow-derived endothelial progenitor cells (EPCs) are recruited into the circulation. To investigate whether antihypertensive treatment has an influence on the number of circulating EPCs, patients with essential hypertension were treated either with the angiotensin receptor antagonist telmisartan, the calcium channel blocker nisoldipine, or their combination for 6 weeks. At baseline and after 3 and 6 weeks of treatment, EPCs were identified and quantified by fluorescence-activated cell sorting (FACS) analysis and by their capacity to generate colony-forming units of the endothelial lineage (CFU-EC) in a methylcellulose-based assay. During treatment, patients in the nisoldipine groups, but not in the telmisartan group, showed a significant mobilization of EPCs, which in part had the capacity to generate large-sized colonies comprising more than 1,000 cells. Moreover, a remarkable correlation between the number of CFU-EC and the number of circulating CD133(+)/CD34(+)/CD146(+) cells was observed, thereby providing strong evidence that cells with this phenotype represent functional EPCs. No correlation was found between the numbers of CFU-EC and the blood pressure levels at any time point during the treatment. Hence, nisoldipine-induced mobilization of EPCs might represent a novel mechanism by which this antihypertensive compound independently of its blood pressure-lowering effect contributes to vasoprotection in patients with essential hypertension
