Estimating personal costs incurred by a woman participating in mammography screening in the National Breast and Cervical Cancer Early Detection Program
Authors: Ekwueme Donatus U. , Hall Ingrid J. , Richardson Lisa C. , Gardner James G. , Royalty Janet , Thompson Trevor D. 
Published: June 2008

AbstractBACKGROUND.The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) covers the direct clinical costs of breast and cervical cancer screening and diagnostic follow‐up for medically underserved, low‐income women. Personal costs are not covered. In this report, the authors estimated personal costs per woman participating in NBCCEDP mammography screening by race/ethnicity and also estimated lifetime personal costs (ages 50‐74 years).METHODS.A decision analysis model was constructed and parameterized by using empiric data from a retrospective cohort survey of mammography rescreening among women ages 50 years to 64 years who participated in the NBCCEDP. Data from 1870 women were collected from 1999 to 2000. The model simulated the flow of resources incurred by a woman participating in the NBCCEDP. The analysis was stratified by annual income into 2 scenarios: Scenario 1, <$10,000; and Scenario 2, from $10,000 to <$20,000. Sensitivity analyses were conducted to appraise uncertainty, and all costs were standardized to 2000 U.S. dollars.RESULTS.In Scenario 1, for all races/ethnicities, a woman incurred a 1‐time cost of $17 and a discounted lifetime cost of $108 for 10 screens and $262 for 25 screens; in Scenario 2, these amounts were $31 and from $197 to $475, respectively. In both scenarios, a non‐Hispanic white woman incurred the highest cost. The sensitivity analyses revealed that >70% of cost incurred was attributable to opportunity cost.CONCLUSIONS.Capturing and quantifying personal costs will help ascertain the total cost (ie, societal cost) of providing mammography screening to a medically underserved, low‐income woman participating in a publicly funded cancer screening program and, thus, will help determine the true cost‐effectiveness of such programs.

Optimization of Click Chemistry of Ferrocene Derivatives on Acetylene‐Functionalized Silicon(100) Surfaces
Authors: Ciampi Simone , Le Saux Guillaume , Harper Jason B. , Gooding J. Justin 
Published: June 2008

AbstractThe optimization of the reaction conditions for copper‐catalyzed azide‐alkyne ‘click’ cyclo‐addition reactions used to covalently confine substituted ferrocene derivatives on passivated silicon(100) surfaces is reported. Variations in the observed reaction yields and the extent of surface contamination as a function of the source of the copper catalyst and the solvent system used in the ‘click’ procedure were evaluated spectroscopically. The electronic communication between the ferrocene centre and the underlying semiconductor surface was investigated by means of cyclic voltammetry and found to be consistent with that expected for a well‐behaved and robust redox interface.
Steady‐state modeling for membrane separation of pretreated soaking effluent under cross flow mode
Authors: Das Chandan , Dasgupta Sunando , De Sirshendu 
Published: June 2008

AbstractA two‐step membrane separation process, namely, nanofiltration (NF), followed by reverse osmosis (RO), is proposed to treat the soaking effluent collected from a tannery. Solution diffusion and osmotic pressure model are combined to predict the steady‐state permeate flux and permeate concentration for continuous, cross flow membrane separation operations. Three flow regimes, namely, laminar, laminar with promoters, and turbulent flow are considered. The extent of polarization on the membrane surface is quantified. For both NF and RO, the extent of polarization increases with increasing transmembrane pressure and decreases with cross flow rate. The model parameters are optimized by comparing the calculated results with the experimental data. © 2008 American Institute of Chemical Engineers Environ Prog, 2008
Doppler compensation for OFDM transmission by sectorised antenna reception
Authors: Klenner Peter , Kammeyer Karl‐Dirk 
Published: June 2008

AbstractRapidly time‐varying channels are a major obstacle for successful data transmission via OFDM. The resulting loss of orthogonality among neighbouring subcarriers leads to intercarrier interference (ICI). Hence, coherent receivers suffer from the impediment of both channel estimation (CE) and subsequent data detection, whereas noncoherent receivers are suffering from reduced correlation between adjacent symbols. Literature contains numerous approaches to cope with this problem working either in time or frequency domain. Our concern in this paper is a novel time‐domain method which relies on the use of multiple directional receive antennas. Each of these antennas experiences only a fraction of the total Doppler spread of a comparable omnidirectional antenna. We will demonstrate that our scheme copes well with large maximum Doppler frequencies. Copyright © 2008 John Wiley & Sons, Ltd.
When do central banks prefer to intervene secretly?
Authors: Ferré Montserrat , Manzano Carolina 
Published: June 2008

AbstractCentral banks often intervene secretly in the foreign exchange market. This secrecy seems to be at odds with the signalling channel. In this article we will analyse when a central bank intervening in the foreign exchange rate market purely through the signalling channel would prefer to act secretly or publicly. By using a microstructure model, we will show that the consistency of the intervention with fundamentals, the volume of noise trading, the weight given to the effectiveness of intervention and the degree of superior information held by the central bank will influence the decision to intervene secretly or publicly.

Evaluation of ion release, cytotoxicity, and platelet adhesion of electrochemical anodized 316 L stainless steel cardiovascular stents
Authors: Díaz M. , Sevilla P. , Galán A. M. , Escolar G. , Engel E. , Gil F. J. 
Published: June 2008

Abstract316L Stainless steel is one of the most used metallic material in orthopedical prosthesis, osteosinthesis plates, and cardiovascular stents. One of the main problems this material presents is the nickel and chromium release, specially the Ni ion release that provokes allergy in a high number of patients. Recently, experimental applications in vitro and in vivo seem to indicate that the thickness of the nature oxide of the stainless steel results in very strong reinforcement of the biological response and reduce the ion release due to the thicker surface oxide. It is possible to grow the natural chromium oxide layer by electrolytic method such anodization. In this study, two main anodization methods to grow chromium oxide on the 316L stainless steel have been evaluated. Nickel and Chromium ions release in human blood at 37°C were detected at times of 1, 6, 11, and 15 days by means of atomic absorption in a graphite furnace (GAAF). Moreover, cytocompatibility tests were carried out. Perfusion experiments were performed to evaluate morphometrically platelet interaction with the material and to explore the potential thrombogenicity. The results showed a good cytocompatibility between the material and the osteoblast‐like cells. However, these anodization methods released between 2 and 10 times more nickel and chromium than the original stainless steel, depending on the method used. Besides, anodized samples shown an increase of the percentage of surface covered by platelets. Consequently, the anodization methods studied do not improve the long‐term behavior of the stainless steel for its application as cardiovascular stents. © 2008 Wiley Periodicals, Inc.

Riboflavin prevents inhibitory effects during the reductive decolorisation of Reactive Orange 14 by methanogenic sludge
Authors: Cervantes Francisco J , López‐Vizcarra María Isabel , Siqueiros Eliane , Razo‐Flores Elías 
Published: June 2008

AbstractBACKGROUND: High‐rate anaerobic reactors represent suitable technologies to achieve efficient decolorisation of azo dyes. However, several anaerobic bioreactors have shown poor performance or even collapsed during decolorisation of azo dyes owing to the inhibitory effects of these contaminants. In this study the inhibitory effects of the azo dye Reactive Orange 14 (RO14) on different syntrophic groups in methanogenic sludge, as well as the catalytic impact of riboflavin, were assessed in batch incubations.RESULTS: Low rates of decolorisation of RO14 by the anaerobic sludge were observed, which decreased with increasing concentration of RO14 (up to 4.8 mmol L−1), when incubations proceeded in the absence of riboflavin. Concomitantly, the methanogenic activity of the anaerobic sludge diminished by up to 65% compared with controls not exposed to RO14. Methylotrophic methanogens were the group most affected by RO14, followed by acetoclastic methanogens, while formate‐utilising methanogens emerged as the group most tolerant to the inhibitory effects of RO14. Acidogenic micro‐organisms were also inhibited by RO14 during decolorisation assays. Addition of riboflavin as a redox mediator increased the decolorisation rate of RO14 up to 53‐fold compared with controls lacking this catalyst. However, the methanogenic activities did not vary significantly regardless of the presence or absence of riboflavin, suggesting that methanogens were not responsible for the enhanced decolorisation observed.CONCLUSION: Redox mediators could prevent the inhibitory effects of recalcitrant azo dyes in anaerobic consortia by decreasing the time of exposure of azo‐reducing micro‐organisms to the pollutants.

Effects of prochloraz and ethinylestradiol on sexual development in Rana temporaria
Authors: Brande‐Lavridsen Nanna , Christensen‐Dalsgaard Jakob , Korsgaard Bodil 
Published: June 2008

AbstractA wide range of environmental xenobiotics that mimic hormones (endocrine‐disrupting chemicals) may cause alterations in sexual development or reproductive function in aquatic organisms such as amphibians when exposed during early sensitive stages. We exposed tadpoles of the Common frog, Rana temporaria, from hatch to metamorphosis, to two different endocrine disruptors, the synthetic estrogen 17α‐ethinylestradiol and the fungicide prochloraz. The object of the study was to assess the effects of these two compounds on the sexual development of the tadpoles by investigating sex ratio, gonadal development, sex steroid concentrations and vitellogenin induction. Histology revealed that a large percentage of all groups were juvenile hermaphrodites at metamorphosis. Tadpoles exposed to 115 and 251 µg/L prochloraz showed a significant increased proportion of males. However, the testosterone concentrations were depressed in those groups. Ethinylestradiol in concentrations of 77 and 159 ng/L EE2 increased whole‐body calcium levels in a dose‐dependent manner indicating induction of the egg yolk protein vitellogenin, verified also by gel electrophoresis. The study shows that ethinylestradiol may induce vitellogenesis and prochloraz may affect the sexual development in Common frogs. J. Exp. Zool. 309A:389–398, 2008. © 2008 Wiley‐Liss, Inc.
Topological torsion related to some recursive sequences of integers
Authors: Barbieri Giuseppina , Dikranjan Dikran , Milan Chiara , Weber Hans 
Published: June 2008

AbstractFor a recursively defined sequence u : = (un) of integers, we describe the subgroup tu (𝕋) of the elements x of the circle group 𝕋 satisfying limn unx = 0. More attention is dedicated to the sequences satisfying a secondorder recurrence relation. In this case, we show that the size and the free‐rank of tu (𝕋) is determined by the asymptotic behaviour of the ratios qn = (un /un –1) and we extend previous results of G. Larcher, C. Kraaikamp, and P. Liardet obtained from continued fraction expansion. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
On the powers of 3/2 and other rational numbers
Authors: Dubickas Artūras 
Published: June 2008

AbstractLetp > q > 1 be two coprime integers. In this paper, we prove several results about subsets of the interval [0, 1) which does or does not contain all the fractional parts {ξ (p /q)n }, n = 0, 1, 2, …, for certain non‐zero real number ξ. We show, for instance, that there are no real ξ for which the union of two intervals [8/39, 18/39] ∪ [21/39, 31/39] contains the set {ξ (3/2)n }, n ∈ N. The most important aspect of this result is that the total length of both intervals 20/39 is greater than 1/2: the same result as above for [0, 1/2) would imply that there are no Mahler's Z ‐numbers which the best known unsolved problem in this area. On the other hand, it is shown that there are infinitely many ξ for which {ξ (3/2)n } ∈ (5/48, 43/48) for each integer n ≥ 0. We also give simpler proofs of few recent results in this area.
