Official guidelines for the on-site treatment of domestic sewage have recently been published by the Danish Ministry of Environment as a consequence of new treatment requirements for single houses and dwellings in rural areas. This paper summarises the guidelines for vertical constructed wetland systems (planted filter beds) that will fulfil demands of 95% removal of BOD and 90% nitrification. ...

The existence of a Paretian and finitely anonymous ordering in the set of infinite utility streams implies the existence of a non-Ramsey set (a nonconstructive object whose existence requires the axiom of choice). Therefore, each Paretian and finitely anonymous quasi-ordering either is incomplete or does not have an explicit description. Hence, the possibility results of Svensson (1980) and of ...

Multiphoton microscopy has emerged in the past decade as a promising tool for noninvasive skin imaging. Our aim was to evaluate the potential of multiphoton microscopy to detect topical corticosteroids side effects within the epidermis and to provide new insights into their dynamics. Healthy volunteers were topically treated with clobetasol propionate on a small region of their forearms under o...

Sexual maturity in poultry is controlled by a complex neural circuit located in the basal forebrain, which integrates the central and peripheral signals to activate hypothalamic gonadotrophin-releasing hormone (GnRH) secretion. This study demonstrated the changes of GnRH-I, POMC and NPY mRNA transcription in hypothalamus and IGF-I and leptin levels in serum of Shaoxing ducks during puberty. Bod...

The S4 transmembrane segments of voltage-gated ion channels move outward on depolarization, initiating a conformational change that opens the pore, but the mechanism of S4 movement is unresolved. One structural model predicts sequential formation of ion pairs between the S4 gating charges and negative charges in neighboring S2 and S3 transmembrane segments during gating. Here, we show that pair...

The objective was to determine whether the use of estradiol-17beta (E2) at the initiation of short dry periods prevented an anticipated decline in milk production in the subsequent lactation. Lactating Holstein cows (n = 66) were dried at either 60 or 30 d before expected calving. Treatments in a 2 x 2 factorial arrangement included: D60 (n = 19, 60-d dry, no E2), D60 + E2 (n = 18, 60-d dry, E2...

The linear plasmid pDJ12 from Micrococcus D12, isolated from the high-altitude volcanic Diamante Lake in the northwest of Argentina, was completely sequenced and annotated. It is noteworthy that the element is probably conjugative and harbors genes potentially instrumental in coping with stress conditions that prevail in such an extreme environment.

We randomized 66 elderly patients with AML unfit for conventional chemotherapy to receive GCSF from d6 or from d12 after induction-chemotherapy with cytarabine/idarubicin. There was no difference in duration of neutropenia (17 days vs. 19 days, p=0.67) or rate of complications. Delayed treatment can reduce the administration of G-CSF without adverse consequences.
