The asymmetric unit of the title compound, [Co(NO3)2(C12H12N2S)2] n , contains a bis-(pyridin-3-ylmeth-yl)sulfane (L) ligand, an NO3- anion and half a CoII cation, which lies on an inversion centre. The CoII cation is six-coordinated, being bound to four pyridine N atoms from four symmetry-related L ligands. The remaining coordination sites are occupied by two O atoms from two symmetry-related ...

This enterotoxin retained most of its activity after 30 min. at 1OO"C, but was inactivated after 30 min. at 121°C. It will therefore be referred to as the heat-stable enterotoxin or ST. Although ST could occasionally be detected intracellularly in bacteria grown on soft agar cultures, it was mainly extracellular. In some strains of E. coIi its production was controlled by a transmissible plasmi...

Today, most countries are facing national CO2 targets focused on production and direct energy use. However, two important driving forces are increased consumption and changing consumption patterns. In this paper we analyse the impact from household consumption on CO2 emissions. Household energy use is taken into account, as is the consumption of commodities and services produced by industry. Ba...

TO THE EDITOR: Amann et al. (1) tested a fine and worthwhile hypothesis, but their results may raise more questions than are answered. They show that intrathecal fentanyl produced a small reduction in minute ventilation and significantly raised PETCO2 during 100–325 W leg exercise. They propose that since PETCO2 rose, this masked a further fentanyl-induced fall in minute ventilation. They quant...

DNA sequence diversity in the tRNA(leu)-COII portion of the mitochondrial genome was investigated in samples of Apis cerana from Yunnan, China. A fragment of about 480 bp in tRNA(leu)-COII, including a noncoding area and part of COII, was sequenced. The noncoding area was 97-98 bp; 8 haplotypes were found, among which 5 had been reported previously, while 3 were new. The mean diversity of haplo...

We conducted regional cortical blood flow studies using the xenon-133 clearance technique on 12 volunteers during the administration of 25% and 50% N2O and during baseline conditions (breathing room air or 100% O2). Global cortical blood flow was very highly significantly increased above baseline measures in all subjects by 50% N2O (mean increase 37% above 100% O2 condition). A smaller but stil...

Plant mitochondrial group II introns do not all possess hallmark ribozymic features such as the bulged adenosine involved in lariat formation. To gain insight into their splicing pathways, we have examined the physical form of excised introns in germinating wheat embryos. Using RT-PCR and cRT-PCR, we observed conventional lariats consistent with a two-step transesterification pathway for intron...

Acute hypercapnia may develop during periodic breathing from an imbalance between abnormal ventilatory patterns during apnea and/or hypopnea and compensatory ventilatory response in the interevent periods. However, transition of this acute hypercapnia into chronic sustained hypercapnia during wakefulness remains unexplained. We hypothesized that respiratory-renal interactions would play a criti...

The single ion magnetic properties of Co(ii) are affected by the details of the coordination geometry of the ion. Here we show that a geometry close to trigonal prismatic which arises when the ligand 6,6'-((1Z)-((piperazine-1,4-diylbis(propane-3,1-diyl))bis(azanylylidene))bis(methanylylidene))bis(2-methoxyphenol) coordinates to Co(ii) does indeed lead to enhanced single-ion behaviour as has pre...

This paper presents an experimental investigation of the individual willingness to pay (WTP) for green electricity. The experimental design comprises a public-choice scenario and a individual-choice scenario. It involves three different payment vehicles for the public promotion of renewables: direct tax, indirect tax, and CO2 tax. We test for the extent of freeriding, the impact of different pa...
