Indications, management, and outcome of long-term positive-pressure ventilation in dogs and cats: 148 cases (1990–2001)
Authors: Hopper Kate , Haskins Steve C. , Kass Philip H. , Rezende Marlis L. , Aldrich Janet 
Published: January 2007

Abstract
Objective—To determine outcome of positive-pressure ventilation (PPV) for 24 hours or longer and identify factors associated with successful weaning from PPV and survival to hospital discharge in dogs and cats.
Design—Retrospective case series.
Animals—124 dogs and 24 cats that received PPV for 24 hours or longer.
Procedures—Medical records were reviewed for signalment, primary diagnosis, reason for initiating PPV, measures of oxygenation and ventilation before and during PPV, ventilator settings, complications, duration of PPV, and outcome. Animals were categorized into 1 of 3 groups on the basis of the reason for PPV.
Results—Group 1 patients received PPV for inadequate oxygenation (67 dogs and 6 cats), group 2 for inadequate ventilation (46 dogs and 16 cats), and group 3 for inadequate oxygenation and ventilation (11 dogs and 2 cats). Of the group 1 animals, 36% (26/73) were weaned from PPV and 22% (16/73) survived to hospital discharge. In group 2, 50% (31/62) were weaned from PPV and 39% (24/62) survived to hospital discharge. In group 3, 3 of 13 were weaned from PPV and 1 of 13 survived to hospital discharge. Likelihood of successful weaning and survival to hospital discharge were significantly higher for group 2 animals, and cats had a significantly lower likelihood of successful weaning from PPV, compared with dogs. Median duration of PPV was 48 hours (range, 24 to 356 hours) and was not as-sociated with outcome.
Conclusions and Clinical Relevance—Results suggested that long-term PPV is practical and successful in dogs and cats.

Abstract
Objective—To assess the clinical course of disease and risk factors associated with outcome in dogs with tetanus.
Design—Retrospective case series.
Animals—38 dogs with tetanus.
Procedures—Data were collected from medical records of dogs with tetanus, including signalment; wound characteristics; initial clinical signs; severity of worst clinical signs; time to wound management, antimicrobial treatment, and antitoxin administration; and 28-day survival rate. Statistical analyses were performed to evaluate relationships between the potentially predictive variables and disease progression and outcome.
Results—The 28-day survival rate was 77% (among 35 uncensored dogs). The most common initial clinical signs in affected dogs were ocular (n = 18) and facial (11) abnormalities. Nineteen dogs progressed to recumbency with severe muscle spasms, and 14 dogs had high or low heart rate or blood pressure values. Eight dogs died or were euthanized because of complications of tetanus. There was a significant association between younger age and development of more severe clinical signs. Furthermore, a significant inverse relationship between development of severe clinical signs and survival was identified. There was no as-sociation between earlier initiation of wound management, antimicrobial administration, or antitoxin administration and either progression of signs or 28-day survival rate. Wound type was not associated with 28-day survival rate.
Conclusions and Clinical Relevance—Results suggest that younger dogs with tetanus may be more likely to develop severe clinical signs. The prognosis for survival in dogs with tetanus is good if abnormalities in heart rate or blood pressure values do not develop.
Molecular identification of Phialophora oxyspora as the cause of mycetoma in a horse

Published: January 2007

Abstract
Case Description—An 18-year-old mare was evaluated for an oral mass that developed after extraction of a broken incisor.
Clinical Findings—An ulcerated, firm, darkly pigmented, approximately 5-cm-diameter spherical mass involved the gingiva lateral and dorsal to the right first to third maxillary incisors. Osteolysis of the roots of the first and second right maxillary incisors and periosteal proliferation of the adjacent premaxilla margins were apparent on radiographs. Histologic examination of the mass revealed multiple coalescing and ramifying foci of abscess formation, each containing a well-defined, discrete, black mass (2 to 7 mm in diameter). Myriad fungal hyphae enmeshed in a black, granular, cementlike material were within each of the black structures. Mycetoma was the histologic diagnosis. The causative agent could not be identified via culture because of lack of distinguishing characteristics. Fungal DNA was isolated from frozen fungal cultures and paraffin sections. The D1/D2 domains of the large subunit P gene rDNA were amplified and sequenced. The sequences of the D1/D2 domains of both isolates were 96% homologous with those of Phialophora oxyspora.
Treatment and Outcome—The mass was surgically excised, the local area curetted, and the wound allowed to heal by second intention. Postoperative treatment consisted of administration of phenylbutazone and IV administration of sodium iodide followed by oral administration of potassium iodide. There was no evidence of recurrence 1 year later.
Clinical Relevance—Mycetomata should be a differential diagnosis for equine gingival masses. Identification of the fungal agent can be critical for selection of optimal treatments. Molecular methods may permit definitive identification when standard phenotypic-based identification criteria are inconclusive.

Abstract
Case Description—15 llamas and 34 alpacas between 3 weeks and 18 years old with fecal oocysts or intestinal coccidial stages morphologically consistent with Eimeria macusaniensis were examined. Nineteen of the camelids were admitted dead, and 30 were admitted alive. Camelids admitted alive accounted for 5.5% of all camelid admissions during this period.
Clinical Findings—Many severely affected camelids had signs of lethargy, weight loss, decreased appetite, and diarrhea. Camelids with clinical infection also commonly had evidence of circulatory shock, fat mobilization, and protein loss. Nonsurviving camelids also had evidence of shock, edema, bile stasis, renal insufficiency, hepatic lipidosis, muscle damage, relative hemoconcentration, and sepsis. Postmortem examination frequently re-vealed complete, segmental replacement of the mucosa of the distal portion of the jejunum with coccidial meronts and gamonts. For 17 of 42 camelids, results of initial fecal examinations for E macusaniensis were negative.
Treatment and Outcome—Most camelids admitted alive were treated with amprolium hydrochloride, plasma, and various supportive treatments. Fifteen of the 30 treated camelids died or were euthanized.
Clinical Relevance—Findings suggest that E macusaniensis may be an important gastrointestinal tract pathogen in camelids of all ages. Clinical signs were frequently nonspecific and were often evident before results of fecal examinations for the parasite were positive. As with other coccidia, severity of disease was probably related to ingested dose, host immunity, and other factors. The clinical and herd relevance of positive fecal examination results must be determined.
Model atmosphere parameters of the binary systems COU1289 and COU1291
Authors: Al‐Wardat M. A. 
Published: January 2007

AbstractThe spectral energy distributions between λ 3700 Å and λ 8100 Å of the binary systems COU1289 and COU1291 have been measured with the Carl‐Zeiss‐Jena 1 m telescope of the Special Astrophysical Observatory. Their B, V, R magnitudes and B – V colour indices were computed and compared with earlier investigations. Model atmospheres of both systems were constructed using a grid of Kurucz blanketed models, their spectral energy distributions in the continuous spectrum were computed and compared with the observational ones. The model atmosphere parameters for the components of COU1289 were derived as: T aeff = 7100 K, T beff = 6300 K, log g a = 4.22, log g b = 4.22, R a = 1.50 R⊙, R b = 1.40 R⊙, and for the components of COU1291 as: T aeff = 6400 K, T beff = 6100 K, log g a = 4.20, log g b = 4.35, R a = 1.47 R⊙, R b = 1.12 R⊙. The spectral types of both components of the system COU1289 were concluded as F1 and F7, and of the system COU1291 as F6 and F9. Finally the formation and evolution of the systems were discussed.

Correction of SOHO CELIAS/SEM EUV measurements saturated by extreme solar flare events

Published: January 2007

AbstractThe solar irradiance in the Extreme Ultraviolet (EUV) spectral bands has been observed with a 15 s cadence by the SOHO Solar EUV Monitor (SEM) since 1995. During remarkably intense solar flares the SEM EUV measurements are saturated in the central (zero) order channel (0.1–50.0 nm) by the flare soft X‐ray and EUV flux. The first order EUV channel (26–34 nm) is not saturated by the flare flux because of its limited bandwidth, but it is sensitive to the arrival of Solar Energetic Particles (SEP). While both channels detect nearly equal SEP fluxes, their contributions to the count rate is sensibly negligible in the zero order channel but must be accounted for and removed from the first channel count rate. SEP contribution to the measured SEM signals usually follows the EUV peak for the gradual solar flare events. Correcting the extreme solar flare SEMEUV measurements may reveal currently unclear relations between the flare magnitude, dynamics observed in different EUV spectral bands, and the measured Earth atmosphere response. A simple and effective correction technique based on analysis of SEM count‐rate profiles, GOES X‐ray, and GOES proton data has been developed and used for correcting EUV measurements for the five extreme solar flare events of July 14, 2000, October 28, November 2, November 4, 2003, and January 20, 2005. Although none of the 2000 and 2003 flare peaks were contaminated by the presence of SEPs, the January 20, 2005 SEPs were unusually prompt and contaminated the peak. The estimated accuracy of the correction is about ±7.5% for large X‐class events. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractThe Hinsberg test to recognize the type of amine (1°–3° amines), which has been established for more than 100 years and well documented in textbooks, is not possible without conducting complicated organic reactions. We report for the first time unique chemosensors that are capable of showing selective color changes toward 1°–3° amines as a color version of the Hinsberg test. This simple and straightforward qualitative analysis, using the synthesized novel compounds herein, can be considered a new innovative tool for discriminating 1°–3° amines as an alternative to the historical Hinsberg test.
The Combined Catalytic Action of Solid Acids with Nickel for the Transformation of Polypropylene into Carbon Nanotubes by Pyrolysis

Published: January 2007

AbstractThe effects of both organically modified montmorillonite (OMMT) and Ni2O3 on the carbonization of polypropylene (PP) during pyrolysis were investigated. The results from TEM and Raman spectroscopy showed that the carbonized products of PP were mainly multiwalled carbon nanotubes (MWNTs). Surprisingly, a combination of OMMT and Ni2O3 led to high‐yield formation of MWNTs. X‐ray powder diffraction (XRD) and GC–MS were used to investigate the mechanism of this combination for the high‐yield formation of MWNTs from PP. Brønsted acid sites were created in degraded OMMT layers by thermal decomposition of the modifiers. The resultant carbenium ions play an important role in the carbonization of PP and the formation of MWNTs. The degradation of PP was induced by the presence of carbenium ions to form predominantly products with lower carbon numbers that could be easily catalyzed by the nickel catalyst for the growth of MWNTs. Furthermore, carbenium ions are active intermediates that promote the growth of MWNTs from the degradation products with higher carbon numbers through hydride‐transfer reactions. The XRD measurements showed that Ni2O3 was reduced into metallic nickel (Ni) in situ to afford the active sites for the growth of MWNTs.
Contraction Process of an Electroactive Actuator Based on a One Microsecond Atomistic Molecular Dynamics Simulation
Authors: Zanuy David , Alemán Carlos 
Published: January 2007

AbstractThe contraction process of an electroactive actuator constituted by calix[4]arene units and quaterthiophene segments has been investigated at the microscopic level by using atomistic molecular dynamics simulations in dichloromethane solution using explicit solvent molecules. Results derived from a 1 μs trajectory of the oxidized and deprotonated actuator indicate that the contraction occurs through a non‐concerted mechanism in which each actuating units present in the system behave independently. The efficiency of the contraction process can be reduced by the presence of secondary conformational transitions in the calix[4]arene scaffolds. Accordingly, the drastic reduction of the molecular length expected during the contraction process can be limited by such transitions, which involve the rotational isomerism of a phenolate ring. However, such type of conformational transitions does not compromise the actuator power due to its intrinsic capacity to adopt compact molecular arrangements. On the other hand, the rate of the contraction process is influenced by the presence of solvent molecules, which have been found to reduce it by a factor of about 1000.
Bromoallenes as Allyl Dication Equivalents in the Presence or Absence of Palladium(0): Direct Construction of Bicyclic Sulfamides Containing Five‐ to Eight‐membered Rings by Tandem Cyclization of Bromoallenes
Authors: Hamaguchi Hisao , Kosaka Shohei , Ohno Hiroaki , Fujii Nobutaka , Tanaka Tetsuaki 
Published: January 2007

AbstractA highly regioselective synthesis of bicyclic sulfamides is described. Based on our recent discovery that bromoallenes can act as allyl dication equivalents in the presence of a palladium catalyst and alcohol, we investigated tandem cyclization of bromoallenes bearing a sulfamide group. It is found that some bromoallenes act as allyl dication equivalents even in the absence of a palladium(0) catalyst to afford cyclosulfamides containing five‐ or six‐membered rings. While the palladium‐free cyclization is dependent on the substrate structure affording the bicyclic sulfamides through the first cyclization onto the proximal or central carbon atom of the bromoallenes, the palladium‐catalyzed reaction strongly promotes the first cyclization onto the central allenic carbon atom to afford bicyclic sulfamides containing a seven‐ or eight‐membered ring. Formation of two types of bicyclic sulfamides from single bromoallenes by simply changing the reaction conditions is also described.
Pride and respect in volunteers' organizational commitment
Authors: Boezeman Edwin J. , Ellemers Naomi 
Published: January 2007

AbstractAs volunteer organizations cannot rely on instrumental means to motivate their workers, we examine organizational commitment as a focal indicator of work motivation among volunteers. Based on a social identity analysis and previous work among paid employees, we argue that pride in the organization and respect from the organization predicts organizational commitment among volunteers. We further propose that among volunteers the perceived importance of volunteer work is an antecedent of pride, and that perceived support from the organization is an antecedent of respect. In this study among volunteer workers, Structural Equation Modeling (SEM) offers empirical support for our hypothesized model. In addition to the theoretical significance of developing a model that explains organizational commitment among volunteer workers, this study also has practical relevance, as it indicates that volunteer organizations might convey the importance of volunteer work and provide organizational support to induce pride and respect as a means of enhancing organizational commitment among their volunteers.

How do i know what i feel? Evidence for the role of self‐categorisation in symptom perceptions
Authors: St. Claire Lindsay , Clift Alex , Dumbelton Laura 
Published: January 2007

AbstractThis paper extends the self‐categorisation model of symptom appraisals to predict that individuals who believe they have a given illness will perceive concurrent symptoms relevant to that illness to be more severe when they categorise themselves as members of a group of people with that illness. These predictions are supported with opportunity samples of individuals reporting, or not reporting a common cold (Study 1, N = 60) and reporting colds or tinnitus (Study 2, N = 64). In both studies, relevant symptoms were rated as more severe when illness group memberships were salient. The methodological, theoretical and clinical implications of these findings and possible therapeutic applications of self‐categorisation theory (SCT) to symptom perceptions are discussed.

Non‐linear system identification of the versatile‐typed structures by a novel signal processing technique
Authors: Zhang Jian , Sato Tadanobu , Iai Susumu 
Published: January 2007

AbstractNon‐linear structural identification problems have raised considerable research efforts since decades, in which the Bouc–Wen model is generally utilized to simulate non‐linear structural constitutive characteristic. Support vector regression (SVR), a promising data processing method, is studied for versatile‐typed structural identification. First, a model selection strategy is utilized to determine the unknown power parameter of the Bouc–Wen model. Meanwhile, optimum SVR parameters are selected automatically, instead of tuning manually. Consequently, the non‐linear structural equation is rewritten in linear form, and is solved by the SVR technique. A five‐floor versatile‐type structure is studied to show the effectiveness of the proposed method, in which both power parameter known and unknown cases are investigated.

Computation of collection area and probability of lightning strikes to structures using the electrogeometric model
Authors: Metwally I. A. , Heidler F. 
Published: January 2007

AbstractIn IEC 62305‐1 standard, the design of the air termination systems is based on the electrogeometric model using the rolling sphere method. Unfortunately, it does not give direct information about the probability of how often a lightning strike is expected to a possible striking point, which is crucial for the modern risk management. This paper introduces a numerical method to calculate the probability of lightning strikes to structures using an extended electrogeometric model to obtain the probability of a lightning strike to different locations of any building. Many arrangements of isolated single, combined, and two structures are investigated in the light of computing the collection area and the probability of lightning strikes. The results reveal that the computed collection area has shown that the rolling sphere radii of IEC 62305‐1 standard underestimates it and the best location of lightning rods can be easily found for any structure.

Engineering and development: interrogating concepts and practices
Authors: Robbins Peter T. , Crow Ben 
Published: January 2007

AbstractMany problems faced by the South are rooted as much in longstanding social, economic and environmental difficulties as in the dearth of appropriate engineering solutions. Constraints range from the institutional, to the cultural, to the technological and spatial. Engineers engage with these hurdles in different ways. The contributors to this policy arena map out different ways institutions and engineers connect with the challenges, whether informally, or out of necessity, or through the iterative unfolding of society and technology. In so doing, they add to discussions about how policy can support best practice in engineering. Copyright © 2007 John Wiley & Sons, Ltd.
On the invariant measure for the quasi‐linear Lasota equation
Authors: Dawidowicz Antoni Leon , Haribash Najemedin , Poskrobko Anna 
Published: January 2007

AbstractThe problem of the existence of the invariant measure is important considering its connections with chaotic behaviour. In the papers (Zesz. Nauk. Uniw. Jagiellońskiego, Pr. Mat. 1982; 23:117–123; Ann. Pol. Math. 1983; XLI:129–137; J. Differential Equations 2004; 196:448–465) the existence of invariant and ergodic measures according to the dynamical system generated by the Lasota equation was proved, i.e. the equation describing the dynamics and becoming different of the population of cells. In this paper, the existence of such measure for the quasi‐linear Lasota equation is proved. This measure is the carriage of the measure described by Dawidowicz (Zesz. Nauk. Uniw. Jagiellońskiego, Pr. Mat. 1982; 23:117–123). Copyright © 2006 John Wiley & Sons, Ltd.
