Automated Negotiation for Provisioning Virtual Private Networks Using FIPA-Compliant Agents
No full textThis paper describes the design and implementation of negotiating agents for the task of provisioning virtual private networks. The agents and their interactions comply with the FIPA specification and they are implemented using the FIPA-OS agent framework. Particular attention is focused on the design and implementation of the negotiation algorithms

Evolution of the G+C content frontier in the rat cytomegalovirus genome
No full textWithin the 230138 bp of the rat cytomegalovirus (RCMV) genome, the G+C content changes abruptly at position 142644, constituting a G+C content frontier. To the left of this point, overall G+C content is 69.2%, and to the right it is only 47.6%. A region of extremely low G+C content (33.8%) is found in the 5 kb immediately to the right of the frontier, in which there are no predicted coding sequences. To the right of position 147501, the G+C content rises and predicted coding sequences reappear. However, these genes are much shorter (average 848bp, 50% G+C) than those in the left two-thirds of the genome (average 1462bp, 70% G+C). Whole genome alignment of several viruses indicates that the initial ultra-low G+C region appeared in the common ancestor of the genera Cytomegalovirus and Muromegalovirus, and that the lowering of G+C in the right third has been a subsequent process in the lineage leading to RCMV. The left two-thirds of RCMV has stop codon occurrences at 67.5% of their expected level, based on a modified Markov chain model of stop codon distribution, and the corresponding figure for the right third is 78%. Therefore, despite heavy mutation pressure, selective constraint has operated in the right third of the RCMV genome to maintain a degree of gene length unusual for such low G+C sequences
Roles of Fiscal Policy in New Zealand
No full textEconomic growth is one of the objectives of the current government. Fiscal policy, encompassing government expenditure and taxation decisions, can significantly impact on economic growth. This paper proposes a framework which views fiscal policy through three lenses and applies this approach to consider how fiscal policy affects economic growth. The three lenses are: fiscal sustainability, fiscal structure and fiscal stabilisation. The paper reviews international literature pertaining to these three lenses and discusses the extent to which these lenses are incorporated into New Zealand’s current fiscal framework. Contemporary New Zealand fiscal challenges are discussed and, in light of these challenges, the paper concludes with consideration of areas to investigate which may yield improvements to the New Zealand fiscal framework.Fiscal policy, sustainability, stability, structure, taxation, government spending, economic growth
Buckle.
No full textPatent for a buckle "wherein a closed frame or box is employed that is formed with a smooth exterior surface to avoid contact with and injury to the animals on which it is used, and prevent the reins from contacting therewith, and dispensing with the use of a guard thereover; and at the same time producing a secure fastening that is applied to straps without the necessity of the employment of stitches or other modes of fastening" (lines 9-18)
Anatomic Success of Scleral Buckling for Rhegmatogenous Retinal Detachment - A Retrospective Study of 524 Cases
No full textBackground/Aim: Our purpose was to investigate the anatomic success of scleral buckling surgery for rhegmatogenous retinal detachment. Material and Methods: A total of 524 consecutive patients were retrospectively analysed. Several parameters including the lens status, number of breaks and extent of retinal detachment, preoperative proliferative vitreoretinopathy and refractive errors were examined. The minimum follow-up was 6 months. The primary success rate was defined as anatomic success being stable over a period of at least 6 months after surgery. The secondary success rate was defined as anatomic success after the second intervention if necessary. Besides an analysis over all patients, the patients were grouped according to the severity of the preoperative situation in simple, medium and severe cases. Results: The overall primary anatomic success rate was 84.7% and the secondary success rate 96.4% after 1 initial scleral buckling surgery and 1 additional surgery in case of persisting retinal detachment, and 19.1% of the patients with an initially attached retina after 1 scleral buckling surgery experienced a redetachment in the postoperative course and were successfully treated in 60/85 cases. In phakic patients (n = 359) the primary success rate was 89.7%, whereas in pseudophakic patients (n = 165) a primary success rate of 73.9% was obtained. The primary success was additionally influenced by the extent of the retinal detachment measured in clock hours (p <0.001), undetected holes (p = 0.004), small (p = 0.037) and no gas tamponade (p = 0.021). In simple, medium and severe cases, phakic patients always achieved better anatomic results (89.9, 89.1 and 90.2%) compared to pseudophakic ones (82.5, 70.3 and 36.4%). Conclusion: Scleral buckling is a very good surgical option in phakic patients irrespective of the preoperative severity and simple cases in pseudophakic patients. Scleral buckling represents a surgical technique worth being trained and performed in the light of favourable results especially in phakic eyes. Copyright (C) 2010 S. Karger AG, Base

Oxane HD vs silicone oil and scleral buckle in retinal detachment with proliferative vitreoretinopathy and inferior retinal breaks.
No full textBACKGROUND: To compare pars plana vitrectomy (PPV) with 1300 cs silicone oil and scleral buckle (SB) vs PPV with Oxane HD tamponade for rhegmatogenous retinal detachment (RRD) with inferior retinal breaks (IRB).
METHODS: Twenty eyes of 20 consecutive patients with primary inferior RRD and PVR >or=CP2 were alternatively assigned to PPV and 1300 cs silicone oil and segmental SB in the inferior periphery (group 1, n = 10) or PPV with Oxane HD (group 2, n = 10) in order of presentation. Silicone oil/Oxane HD removal was performed 12 weeks after surgery. Subjects were followed up for 6 months from oil removal.
RESULTS: Operative time was lower in Oxane HD group (P = 0.012). In both groups, the retina was primary reattached at the third month after oil removal in nine eyes (90%). At the end of follow-up, retina was reattached in nine eyes (90%) in group 1 (including one eye with oil in situ), and in eight eyes (80%) in group 2 (P > 0.05).
CONCLUSIONS: Silicone oil+SB and Oxane HD appear equal for primary RRD with IRB, but a large multi-centre study is required. Oxane HD permitted a reduced operative time
