"Seit Jahren werden durch die Forschungs- und Transferförderung Mittel in Projekte investiert, die innovative technische und organisatorische Lösungen für eine umweltfreundliche Wirtschaftsweise erforschen. Die Diskusion der Ergebnisse in die Breite ist jedoch kein selbstlaufender Prozess - der Transfer in Unternehmen und alle weiteren wirtschaftenden Systeme funktioniert sehr schleppend. Von daher hatte das Forschungszentrum Nachhaltigkeit der Universität Bremen den Auftrag, im Projekt Integriertes Kleinbetriebsmanagementsystem EcoStep die Thematik der Verbreitung und des Transfers von Ecostep wissenschaftlich zu begleiten mit dem Ziel, ein Konzept zur Erhöhung des Verbreitungsgrades zu erstellen. Hierbei gilt es zu berücksichtigen, dass im Konzept von EcoStep bereits einige Transferelemente eingebaut sind (bspw. die Niederschwelligkeit). Das Managementsystem EcoStep wurde von Experten zusammen mit Vertretern von Unternehmen, Verbänden und Behörden konzipiert, um kleine und mittlere Unternehmen (KMU) dabei zu unterstützen, den Anforderungen des Marktes und der Bezugsgruppen gerecht zu werden. EcoStep richtet sich insbesondere an KMU, da es diesen Unternehmen besonders schwer fällt, die notwendigen Ressourcen aufzuwenden um eine solche Professionalisierung einzuleiten. (...)"

In den nächsten Jahren werden bei den meisten kleinen und mittleren Unternehmen (KMU) Smart Meter verpflichtend eingebaut. Mit speziellen Softwares können die Unternehmen dann zum ersten Mal ihren Energieverbrauch genauer nachvollziehen. Das ermöglicht ihnen verschiedene Analysen, um ihren Stromverbrauch und ihre Kosten zu reduzieren. Smart-Meter-Daten können darüber hinaus auch als Grundlage für Investitionsentscheidungen genutzt werden, etwa um die Wirtschaftlichkeit von Energieeffizienztechnologien oder Photovoltaikanlagen zu bewerten. Davon würden nicht nur die KMU unmittelbar profitieren, sie können so auch einen substanziellen Beitrag zur Energiewende leisten. Allerdings ist davon auszugehen, dass ein Großteil der KMU nicht über die zeitlichen Ressourcen und die fachlichen Kompetenzen verfügt, die notwendigen Analysen ihrer Stromverbräuche selbst durchzuführen. Welche Analysen möglich sind und was jetzt nötig ist, damit die neuen Möglichkeiten ausgeschöpft werden, beschreiben die Autor*innen in dem vorliegenden Paper - und geben vier Handlungsempfehlungen, um das Potenzial des Smart-Meter-Rollouts für KMU tatsächlich voll zu nutzen.

A Campargue-type source of an intense, triply differentially pumped supersonic beam of atoms (He, Ne, Ar) and molecules (N2) for use in high-resolution collision experiments is described. Using stagnation pressures of (1–10) bar, nozzle diameters of (0.05–0.25) mm, and skimmer diameters of (0.5–1.0) mm, the center-line intensity and collimated target density are quantitatively characterized by electron impact ionization in conjunction with total ion collection. Optimum densities in a target plane, located about 160 mm from the nozzle, range from 1012 cm−3 (N2) to 8×1012 cm−3 (He) at background densities which are about 1% of the beam densities. The results are compared with values calculated for ideal supersonic expansions. © 2000 American Institute of Physics.

: Three patients with actinically damaged skin had scaling lesions clinically resembling actinic keratoses. Histologic examination of the lesions disclosed transepidermal elimination (TE) of degenerated (solar elastotic) dermal connective tissue via a transepidermal canal, a previously undescribed phenomenon.

A 12-year-old girl developed a periorbital leukoderma from contact with swim goggles. She had worn the same goggles the preceding year and re-used them after the leukoderma had cleared without any ill effects. The hypopigmentation was believed to be caused by the leakage of breakdown products in the neoprene rubber or glue. These breakdown products may have caused a toxic rather than an allergic reaction on skin contact, inhibiting melanin production possibly by competitive inhibition of tyrosine oxidation. These chemical compounds probably leaked from the goggles and were eventually exhausted. This possibility may explain why the leukoderma did not recur after re-use of the goggles.

GOETTE, A., et al.: Pacing of Bachmann's Bundle After Coronary Artery Bypass Grafting. The purpose of this randomized, prospective trial was to determine if Bachmann's bundle pacing reduces the incidence of AF after CABG. The study included 161 patients with no history of AF who were randomized to three groups. Group 1 included 50 patients as controls. Group 2 included 60 patients who had an epicardial wire placed at the lateral wall of the right atrium. In the 51 patients of group 3, the wire was placed at the Bachmann's bundle. In groups 2 and 3, atrial pacing (AAI 96 beats/min) was initiated immediately after CABG and continued for 5 days. The study endpoint was AF lasting ≥ 1 minute. Baseline clinical parameters were similar in all three groups. The incidence of AF was not reduced by pacing (group 1: 42%; group 2: 48%; group 3: 37%; P = NS). The paced P wave duration was increased in group 2 (129 ± 14 ms vs group 3: 96 ± 21 ms; P 〈 0.05). Paced P wave duration was a risk factor for postoperative AF (odds ratio 1.015; 95% CI 1.0021–1.028; P 〈 0.05). Analysis comparing the pacing groups revealed a reduction in AF during Bachmann's bundle pacing (50 vs 29%; P 〈 0.01). Pacing thresholds were significantly better at Bachmann's bundle compared to group 2. In conclusion, an anatomically guided pacing at the Bachmann's bundle does not reduce the overall incidence of postoperative AF compared to controls. However, the Bachmann's bundle offers favorable capabilities for postoperative atrial pacing, and thus it is a preferable site for electrode placement if postoperative atrial pacing is required.

GELLER, J.C., et al.: Changes in AV Node Conduction Curves Following Slow Pathway Modification. Dual AV node physiology often persists after successful slow pathway (SP) ablation, and the mechanism of tachycardia elimination is unresolved. Therefore, AV node conduction curves were analyzed following successful ablation (4 ± 1 energy applications) in 85 consecutive patients (58 women, age 50 ± 2 years) with typical AVNRT. Twenty-seven patients (32%) had complete elimination (group 1) whereas 58 (68%) patients had persistence (group 2) of dual AV node physiology. A significant increase in the AV node Wenckebach cycle length (WB-CL) was observed in both groups (310 ± 9 to 351 ± 15 ms in group 1, and 325 ± 8 to 369 ± 9 ms in group 2, P 〈 0.05). A decrease in the fast pathway (FP) ERP (339 ± 15 to 279 ± 12 ms) and an increase in the maximum FP AH interval (141 ± 5 to 171 ± 7) were observed only in group 1 (P 〈 0.05). In group 2, no change in the SP ERP (267 ± 7 to 280 ± 10 ms) was observed, and the change in the maximum SP-AH following ablation showed a significant inverse relation to the maximum SP-AH at baseline in group 2. In conclusion, (1) an increase in the WB-CL is observed independent of the persistence or elimination of dual physiology after successful ablation; (2) when dual physiology is eliminated, significant changes in the FP ERP and the maximum FP-AH occur; (3) when dual physiology persists, FP physiology and the SP ERP remain unchanged, and a significant inverse relation between the change in the maximum SP-AH following ablation and the maximum baseline SP-AH is observed.

An increase in sinus rate has been previously described in patients with AV node reentry (AVNRT) following successful A V node modification. This increase could either be a specific sign of elimination of slow pathway conduction or it could be a consequence of energy application in the posteroseptal area. Thus, we compared the changes in sinus cycle length following successful slow pathway ablation (defined as complete elimination of dual AV node physiology) in patients having AVNRT with those in patients undergoing successful ablation of a posteroseptal atriovetriricular accessory connection. Twenty five patients (16 women and 9 men, mean age 41 ± 4 years) with typical AVNRT (cycle length 378 ± 12 ms and 29 patients (16 women and 13 men, age 34 ± 5 years) with an accessory connection (17 manifest and 12 concealed) were studied. The electrophysiology study was performed during sedation with Fentanyl and Midazolam. The mean number of energy applications was 3 ± 1 for successful slow pathway ablation and 4 ± 1 for successful ablation of the accessory connection (p:NS). Following the successful energy application, the sinus cycle length decreased significantly 776 ms at baseline to 691 ms in patients with AVNRT. Following successful ablation of the posteroseptal AC, sinus cycle length decreased from 755 ms at baseline to 664 ms (p 〈 0.05 in both groups [difference between groups not significant]). The decrease in sinus cycle length did not correlate with the number ofRF energy applications required for successful ablation or the total energy delivered. In conclusion, ablation of the AV node slow pathway and a posteroseptal accessory connection results in similar increases in the sinus rate. Thus, the increase in sinus rate is probably due to energy application in the posteroseptal space, possibly due to concomitant destruction of vagal inputs, and it is not specific for elimination of slow pathway conduction.
