    Immortal time: circadian clock properties of rat suprachiasmatic cell lines (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-01-29
    Description: Cell lines derived from the rat suprachiasmatic nucleus (SCN) were screened for circadian clock properties distinctive of the SCN in situ. Immortalized SCN cells generated robust rhythms in uptake of the metabolic marker 2-deoxyglucose and in their content of neurotrophins. The phase relationship between these rhythms in vitro was identical to that exhibited by the SCN in vivo. Transplantation of SCN cell lines, but not mesencephalic or fibroblast lines, restored the circadian activity rhythm in arrhythmic, SCN-lesioned rats. Thus, distinctive oscillator, pacemaker, and clock properties of the SCN are not only retained but also maintained in an appropriate circadian phase relationship by immortalized SCN progenitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Earnest, D J -- Liang, F Q -- Ratcliff, M -- Cassone, V M -- NS35822/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jan 29;283(5402):693-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Anatomy and Medical Neurobiology, College of Medicine, Texas A&M University Health Science Center, College Station, TX 77843-1114, USA. dearnest@tamu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9924030" target="_blank"〉PubMed〈/a〉

    Description / Table of Contents: Zusammenfassung Nur sehr wenige Containerbeladungs-Algorithmen nehmen in ihrer Logik Bezug auf das Gewicht oder die Tragfähigkeit der zu verladenden Güter. Der Artikel versucht, einen Beitrag zur Überwindung dieses Mangels zu leisten. Es wird gezeigt, wie ein Verfahren, das bereits zu einem gewissen Grad in der Literatur behandelt wurde, auf relativ einfache Weise adaptiert werden kann, um die Einbeziehung von Belastbarkeitsüberlegungen zu ermöglichen. Die vorgestellte Methode beruht auf Opportunitätskostenprinzipien. Es wird demonstriert, daß die Ergebnisse beträchtlich besser sein können als die, die man erhält wenn Tragfähigkeit nur als Restriktion bezüglich der im jeweiligen Algorithmusschritt zulässigen Alternativen behandelt wird. Zusätzliche Verfeinerungen der Methodik und Fragen hinsichtlich des praktischen Einsatzes werden ebenfalls diskutiert. Zudem werden potentielle Erweiterungen erörtert, die es ermöglichen, ‚weiche‘ Plazierungsregeln in das Verfahren einzubeziehen.
    Notes: Abstract Only very few of the existing container loading algorithms include in their logic any references to the weight or the load bearing abilities of the items to be stowed. The paper aims to make a contribution to overcoming this shortcoming. It shows how a procedure which has already been evaluated in some detail in the literature can be adapted in a fairly straightforward manner to deal with fragility considerations. The approach suggested is based on opportunity cost notions. It is demonstrated that the results obtained can be vastly superior to a procedure which considers load bearing ability merely in terms of a constraint on the packing options available at each stage. Additional refinements of the basic approach and questions related to its practical implementation are also discussed, as are possible extensions to enable ‘soft’ positioning rules to be incorporated.
