Erkenntnisse über Lüftung und Energieverbrauch sowie Bodenplattendämmung aus Monitoring‐Untersuchungen an einem Passivhaus‐Schulgebäude
Authors: Peper Søren , Kah Oliver , Pfluger Rainer , Schnieders Jürgen 
Published: February 2008

AbstractÜber zweieinhalb Jahre Monitoring einer Passivhaus‐Schule und Kindertagesstätte (KiTa) in Frankfurt a.M. zeigt behagliche raumklimatische Bedingungen bei guten Luftqualitäten. Die Heizwärmeverbrauchswerte liegen wie erwartet niedrig und zeigen Einsparungen um 90 % gegenüber dem Durchschnitt im Bestand. Auch primärenergetisch bewertet, weist die Schule beste Resultate auf. Die Ergebnisse zu weiteren Untersuchungen der effizienten Lüftungsanlage mit Wärmerückgewinnung, den umlaufenden Dämmschürzen als Alternative zur Bodenplattendämmung und dem Einfluss der Luftwechselrate durch die Eingangstüren werden vorgestellt.
Analytical Model for Predicting Thermal Bridge Effects due to Vacuum Insulation Panel Barrier Envelopes
Authors: Tenpierik Martin , van der Spoel Wim , Cauberg Hans 
Published: February 2008

AbstractBecause of a necessity for sustainability and thus for a reduction of the amount of primary energy generated with fossil fuels, vacuum insulation panels (VIP) have recently caught the attention of practitioners in the building industry. The reduction of layer thickness may be considered among the most promising features for large‐scale application of VIPs in buildings. The high barrier laminate (or casing) with relatively high thermal conductivity envelops the core material, thus introducing a thermal bridge at the panel edges and corners. Especially for barrier laminates containing ‘thick’ metal foils, the thermal bridge effect needs to be considered thoughtfully. In this contribution analytical models are presented which on the one hand allow rapid estimation of the VIP's overall thermal performance and on the other hand show the influence of material and geometric parameters on this performance. The analytical models are validated through numerical simulations.
Risk of new aneurysms after surgery for popliteal artery aneurysm
Authors: Ravn H , Wanhainen A , Björck M

Abstract

Background
The risk of developing a new aneurysm after surgery for popliteal artery aneruysm (PAA) is not well known. The aim was to study this risk in a cohort of patients.

Methods
A total of 571 patients who had primary operation for PAA (717 legs) between 1987 and 2002 were identified from the Swedish Vascular Registry (Swedvasc). Of these, 190 patients were re-examined by ultrasonography after a median of 7 (range 2·9–18·7) years.

Results
The number of patients with at least one aneurysm in addition to the PAA was 108 (56·8 per cent) at the index operation and 131 (68·0 per cent) at re-examination. The overall number of aneurysms increased by 41·8 per cent, from 244 to 346. Among the 82 patients who had an isolated PAA at the index operation, 23 developed a new aneurysm; these patients tended to be older (P = 0·004). Bilateral PAA at the index operation was associated with a later development of abdominal aortic aneurysm (P = 0·004). Age (P = 0·004) and hypertension (P = 0·012) at the time of the index operation were associated with multianeurysm disease at any time. Six (4·3 per cent) of 138 legs treated by venous bypass grafts had developed a graft aneurysm by the time of re-examination. No normal arterial segment developed an aneurysm that required surgery within 3 years.

Conclusion
The development of new aneurysms was common in patients with a PAA; lifelong surveillance may be warranted.
Through‐Bond Excited Energy Transfer Mediated by an Amidinium–Carboxylate Salt Bridge in Zn–Porphyrin Free‐Base Porphyrin Dyads
Authors: Otsuki Joe , Kanazawa Yuki , Kaito Atsuko , Shafiqul Islam D.‐M. , Araki Yasuyuki , Ito Osamu 
Published: February 2008

AbstractExcited energy‐transfer processes were investigated for a supramolecular Zn–porphyrin free‐base porphyrin dyad, ZnPA‐2⋅FbPC‐2, in which β‐octaalkylated meso‐diarylporphyrins are connected through an amidinium–carboxylate salt bridge. The rate of energy transfer in the dyad (1.3×109 s−1) is substantially slower than that in the previously reported dyad, ZnPA‐1⋅FbPC‐1 (4.0×109 s−1), in which meso‐tetraarylporphyrins are connected through the same amidinium–carboxylate salt bridge. The Förster‐type mechanism can explain only minor parts of these rates (3.3×108 and 5.1×108 s−1, respectively). Thus, Dexter‐type through‐bond energy transfer may be invoked. Indeed, bridge‐mediated electronic processes would be favored in ZnPA‐1⋅FbPC‐1 over ZnPA‐2⋅FbPC‐2 on the basis of steric and electronic factors. Sterically, the phenyl groups in ZnPA‐2 and FbPC‐2 are more closely perpendicular to the porphyrin planes than those in ZnPA‐1 and FbPC‐1. Electronically, the energy and symmetry of the occupied frontier orbitals should favor ZnPA‐1⋅FbPC‐1 over ZnPA‐2⋅FbPC‐2 in terms of electronic interactions through the bridge. Therefore, the observed trend (ZnPA‐1⋅FbPC‐1>ZnPA‐2⋅FbPC‐2), consistent with these considerations, lends further support to the through‐bond mechanism. Thus, the amidinium–carboxylate salt bridge is effective in mediating through‐bond energy transfer even though the bond is noncovalent.
Modular Phosphite–Oxazoline/Oxazine Ligand Library for Asymmetric Pd‐Catalyzed Allylic Substitution Reactions: Scope and Limitations—Origin of Enantioselectivity
Authors: Diéguez Montserrat , Pàmies Oscar 
Published: February 2008

AbstractA library of phosphite–oxazoline/oxazine ligands L1–L15 a–h has been synthesized and screened in the Pd‐catalyzed allylic substitution reactions of several substrate types. These series of ligands can be prepared efficiently from easily accessible hydroxyl amino acid derivatives. Their modular nature enables the substituents/configurations in the oxazoline/oxazine moiety, alkyl backbone chain and in the biaryl phosphite moiety to be easily and systematically varied. By carefully selecting the ligand components, therefore, high regio‐ and enantioselectivities (ee values up to 99 %) and good activities have been achieved in a broad range of mono‐ and disubstituted linear hindered and unhindered liner and cyclic substrates. The NMR studies on the Pd–π‐allyl intermediates provide a deeper understanding about the effect of the ligand parameters on the origin of enantioselectivity. It also indicates that the nucleophilic attack takes place predominantly at the allylic terminal carbon atom located trans to the phosphite moiety.
