AbstractWe develop and illustrate the concept of ‘hydrologic spiralling’ using a high‐resolution (2 × 2 m grid cell) simulation of hyporheic hydrology across a 1.7 km2 section of the sand, gravel and cobble floodplain aquifer of the upper Umatilla River of northeastern Oregon, USA. We parameterized the model using a continuous map of surface water stage derived from LIDAR remote sensing data. Model results reveal the presence of complex spatial patterns of hyporheic exchange across spatial scales. We use simulation results to describe streams as a collection of hierarchically organized, individual flow paths that spiral across ecotones within streams and knit together stream ecosystems. Such a view underscores the importance of: (1) gross hyporheic exchange rates in rivers, (2) the differing ecological roles of short and long hyporheic flow paths, and (3) the downstream movement of water and solutes outside of the stream channel (e.g. in the alluvial aquifer). Hydrologic spirals underscore important limitations of empirical measures of biotic solute uptake from streams and provide a needed hydrologic framework for emerging research foci in stream ecology such as hydrologic connectivity, spatial and temporal variation in biogeochemical cycling rates and the role of stream geomorphology as a dominant control on stream ecosystem dynamics.

A theory of prestressed thermoelastic Cosserat continua
Authors: Ieşan D. 
Published: March 2008

AbstractThis paper presents a theory of Cosserat thermoelastic solids with initial stresses, initial couple stresses, and initial heat flux. First, the equations governing the infinitesimal deformations superposed on large deformations of Cosserat thermoelastic bodies are established. Then, a linear theory of prestressed Cosserat continua with initial heat flux is derived. The continuous dependence of the solutions upon initial data and body supplies is established.
Gene Diagnosis and Prognostic Significance of Lymph Node Micrometastasis after Complete Resection of Histologically Node‐negative Non‐small Cell Lung Cancer
Authors: Li Shu‐Hai , Wang Zhou , Liu Xiang‐Yan , Liu Fan‐Ying 
Published: March 2008

AbstractBackgroundThe purpose of the present study was to investigate the prevalence of lymph node micrometastasis (LNMM) based on the detection of MUC1 mRNA, and assess the impact of these micrometastases on prognosis after resection of pathologic N0 (pN0) non‐small cell lung cancer (NSCLC).MethodsThe subjects were 89 patients who underwent complete resection of pN0 NSCLC at our department between January 2000 and January 2002. All lymph nodes (402 stations) obtained from these patients were re‐evaluated by reverse transcriptase‐polymerase chain reaction (RT‐PCR) to detect MUC1 mRNA. The diagnosis of LNMM was based on the detection of MUC1 mRNA. The Kaplan‐Meier method was used to calculate the survival rate, and Cox regression multivariate analysis was performed to determine independent prognostic factors.ResultsMicrometastases were detected in 36 lymph node stations (9.0%) from 21 patients (23.6%). The TNM staging of these 21 patients was upregulated from stage IA–IIB to stage IIIA. The 5‐year survival rate of patients with LNMM was significantly lower than that of patients without LNMM (23.8% versus 44.1%; p < 0.05). The results of multivariate analysis confirmed that T status, histology, and LNMM were independent prognostic factors.ConclusionsThe prevalence of LNMM in patients with pN0 NSCLC was 23.6% (21/89). T status, histology, and LNMM were independent prognostic factors.

Published: March 2008

AbstractAn organic–inorganic hybrid composite for use as a coating agent was prepared by mixing linseed oil with hydrophobic octylsilyl titanium dioxide particles having an average diameter of 35 nm (OSI‐TIO2‐35) in volatile silicone. The weight ratio of linseed oil with OSI‐TIO2‐35 was varied from 2:8 to 8:2 and the mixture was spread on a glass plate by dragging an applicator across it. After storing in the oven at 60 °C for 2 days, the composite having the weight ratio of OSI‐TIO2‐35 with linseed oil at 8:2 exhibited very high water‐repellent properties having a water contact angle of 148°. Variation of the water contact angle during storage at 60 °C was monitored. It decreased by 10° in the initial 8 h and then increased by 45° over the next 2 days. Composites containing silicone resin, TMSS BY11‐018, instead of linseed oil were also prepared. The sample having a weight ratio of OSI‐TIO2‐35 with TMSS BY11‐018 at 8:2 also exhibited very high water‐repellent properties with a water contact angle of 152°. The highly hydrophobic surface thus prepared by the coating and drying of those organic‐inorganic hybrid composites was easily transferred to highly hydrophilic surfaces by calcination at 500 °C for 3 h.
Asymptotic stability of Oseen vortices for a density-dependent incompressible viscous fluid
Authors: Rodrigues L. Miguel 
Published: March 2008

In the analysis of the long-time behavior of two-dimensional incompressible viscous fluids, Oseen vortices play a major role as attractors of
any
homogeneous solution with integrable initial vorticity [T. Gallay, C.E. Wayne, Global stability of vortex solutions of the two-dimensional Navier–Stokes equation, Commun. Math. Phys. 255 (1) (2005) 97–129]. As a first step in the study of the
density-dependent
case, the present paper establishes the asymptotic stability of Oseen vortices for slightly inhomogeneous fluids with respect to localized perturbations.

Published: March 2008

ObjectiveConventional cuffed tracheotomy tubes do not prevent aspiration of secretions. Aspiration of saliva may be decreased with the use of a subglottic suction port.Study DesignProspective.MethodsShiley Disposable Cuffed Tracheotomy (DCT) tubes sizes 4, 6, and 8 (Tyco Healthcare, Pleasanton, CA) were compared to Portex Blue Line Ultra Suctionaid (BLUS) tracheotomy tubes sizes 6, 7, and 8 (Fig 1; Smiths Medical, Watford, UK). All tubes were tested in a simulated tracheal model using 10 cc of human saliva with no suction, intermittent suction, and constant suction (15 minutes).ResultsThere was a significant decrease in aspirate between the larger Shiley and BLUS tubes with intermittent suction (mean 8.38 mL Shiley 6 vs 1.60 mL BLUS 7; 8.50 mL Shiley 8 vs 2.80 mL BLUS 8). There was a significant decrease in aspirate between all sizes of Shiley and BLUS tubes with continuous suction. For BLUS 7 and 8, there was a significant difference between intermittent suction (mean, 1.60 mL, 2.80 mL, respectively) and continuous suction (mean, 0.20 mL, 0.60 mL respectively). Shiley and BLUS without suction were equivalent.ConclusionSubglottic suction tracheotomy tubes reduce the risk of aspiration beyond the cuff in a bench‐top model.

Short‐term poststapedectomy air‐bone gaps, long‐term air‐bone gaps, long‐term pure‐tone averages, and long‐term air‐bone gap closures were significantly better for heat‐activated‐crimp versus manual‐crimp prostheses.ConclusionHeat‐activated‐crimping prostheses demonstrated enhanced stapedectomy hearing outcomes versus manual‐crimping prostheses on short‐ and long‐term follow‐up. Three‐dimensional reorientation of the heat‐activated prosthesis may enhance the hearing outcome; however, theoretical nickel allergy considerations, effects of case selection, follow‐up duration, possible eventual loosening of the heat‐activated crimp, and long‐term incus necrosis are considerations requiring continued longitudinal analysis.

ObjectiveTo report the efficacy of botulinum toxin A for radiation‐induced pain, trismus, and masticator spasm in head and neck cancer.Patients and MethodsThis prospective nonrandomized study included patients in complete remission with radiation‐induced pain and trismus with or without masticator spasms. Fifty units of Botox (Allergan) or 250 units of Dysport (Ipsen) were injected transcutaneously into the masseter muscles. Jaw opening was measured and patients answered 20 questions about jaw opening, pain, and cramps, before injection at 1 month.ResultsNineteen patients (7 women, 12 men) were included. Median time after radiation therapy was 5 years (range, 11 months to 22 years). At 1 month, no significant increase in jaw opening was recorded. Improvement was noted in the functional domain (P = 0.004), for pain (P = 0.002) and cramps (P = 0.004), but not in the social (P = 0.83) or emotional (P = 0.43) domains. No side effects occurred.ConclusionsBotulinum toxin did not improve trismus but significantly improved pain scores and masticator spasms (oromandibular dystonia).

Published: March 2008

ObjectivePresent experience in diagnosis and treatment for referred otalgia secondary to cervical spine degenerative disease (CSDD).Study DesignA retrospective study of 123 patients with ear pain.Subjects and MethodsAll patients had a normal otologic examination and diagnosed with unspecified otalgia. The causes for referred otalgia were categorized into Group I: otalgia from non–cervical spine disease (n = 72), and Group II: cervical spine disease–referred otalgia (n = 51). Pain relief following cervical spine physical therapy (CSPT) was assessed.RESULTS: The most common cause for referred otalgia in Group I was Temporomandibular joint (TMJ) dysfunction (46%); most common cervical spine finding in Group II was CSDD (88%). CSPT in those documented patients all reported subjective pain relief.ConclusionAs the population in America ages, CSDD in the elderly will begin to emerge as a major etiologic source for referred otalgia. With a targeted medical history and physical examination one can use directed studies to diagnose CSDD‐referred otalgia, and this pain can be alleviated with CSPT.
MONSTRE SACRÉ:THE QUESTION OF CULTURAL IMPERIALISM AND THE NAPOLEONIC EMPIRE
Authors: ENGLUND STEVEN 
Published: March 2008

ABSTRACTThis review considers, first, current work on the Napoleonic Empire dealing with Switzerland, the three parts of ‘Germany’ (the Rhineland, the ‘Third Germany’, Prussia), Spain, and the so-called ‘national’ question(s) in these countries and regions. It next focuses on recent work on the three parts of ‘Italy’ (the Kingdom of Italy, the départements réunis, and the Kingdom of Naples). But the main body of the review concentrates on the work of Michael Broers: not only his new and remarkable conceptualization of the Empire as containing ‘inner’, ‘outer’, and ‘intermediate’ zones, but also his creative if controversial application of post-modern colonial theory to an analysis of the French in Italy. The review suggests that Broers, for all his brilliance and mastery, has perhaps pressed his arguments and conclusion beyond his evidence base. The latter, while extensive, is too limited to just French perceptions of Italians before 1815, and does not extensively consider Italian reactions to the French presence; nor does it provide significant evidence to buttress Broers's far-reaching conclusions about nineteenth- and twentieth-century Italy.
Spawning and fecundity of Jenyns's sprat, Ramnogaster arcuata, a winter spawner in the temperate waters of the Río de la Plata estuary, Argentina–Uruguay
Authors: Rodrigues Karina A. , Macchi Gustavo J. , Acha Eduardo M. , Militelli María I. 
Published: March 2008

The reproductive biology of the Jenyns's sprat Ramnogaster arcuata in the Río de la Plata area was studied using macroscopic and histological analysis of ovaries. Samples were collected during two research surveys carried out in June 1998 and June 1999. In addition monthly occurrences of this species from historical data were analysed. Jenyns's sprat specimens were mainly observed in open waters of the estuary during winter months. Most of the females collected during June 1998 and 1999 were in the spawning stage. This pattern differs from fish that reproduce in the estuarine waters of the Río de la Plata, which spawn during spring and summer. These results suggest that conditions of productivity and larval retention in the estuary also remain during winter months. This characteristic might be useful for R. arcuata larvae in avoiding competition with other estuarine spawners. Jenyns's sprat is a multiple spawner with indeterminate annual fecundity. A preliminary estimate of spawning frequency (N = 220) indicated a daily percentage of females with postovulatory follicles of 17.35%, which suggests that this species spawns on average once every six days. Batch fecundity, estimated from counts of hydrated oocytes from 40 females, ranged from 669 to 2026 hydrated oocytes in 1998 and from 570 to 1830 hydrated oocytes in 1999. Batch fecundity was fitted to a linear function of total body weight (without ovary) in 1999. Mean relative fecundity was 234 hydrated oocytes per female gram (ovary free) in 1998 and 155 hydrated oocytes per female gram (ovary free) in 1999, and no significant relationship was observed between this parameter and female size. The dry weight of 100 hydrated oocytes ranged between 3.9 and 6.3 mg, these values being significantly higher than those estimated for other species of the Río de la Plata estuary.
Biological observations on the gulper shark Centrophorus granulosus (Chondrichthyes: Centrophoridae) off the coast of Galicia (north-western Spain, eastern Atlantic)
Authors: Bañón R. , Piñeiro C. , Casas M. 
Published: March 2008

The observed Centrophorus granulosus were caught with bottom trawl and longline between 500 and 1300 m depth off the continental slope of Galicia and the Galician Bank (north-eastern Atlantic) between 1996 and 1998. The main biological data obtained were: a maximum recorded size of 166 cm TL (total length); females mature at 147 cm TL; between 1 and 10 mature oocytes by females of 55–80 mm diameter and as many as 6 pups per litter, and size at birth ranging between 35–47 cm TL. These results differ greatly from those compiled in the literature suggesting different populations or perhaps a possible misidentification.
Gap compensation during accelerated hypofractionated radiotherapy in head and neck cancer
Authors: Sanghera Paul , Arnfield John , McConkey Chris , Hartley Andrew 
Published: March 2008

AbstractIntroduction:In squamous-cell carcinoma (SCC) of the head and neck, unplanned gaps risk prolongation of the overall treatment time (OTT) and reduction in tumour control. This audit determines whether further acceleration can safely be employed to compensate for missed treatments during accelerated hypofractionated radiotherapy.Methods:Patients receiving accelerated hypofractionated radiotherapy for SCC of the head and neck were prospectively audited. Outcome measures were OTT, degree of compensation and acute toxicity determined by incidence of grade 3 mucositis, prolonged grade 3 mucositis, grade 3 dysphagia and pain.Results:In the 87 patients identified, the dose administered was 55 Gy in 20 fractions (81 patients), 50 Gy in 20 fractions (1 patient) and 50 Gy in 16 fractions (5 patients). Of those patients receiving 20 fractions, 94% completed within 28 days. Grade 3 mucositis was seen in 56 patients (64%). Compensating for unplanned gaps did not result in any significant increase in toxicity. Administering 6 fractions/week, as compensation, was associated with a lower pain score (p= 0.003) as was receiving 2 fractions on the same day (p= 0.0004).Conclusions:Accelerated hypofractionation is tolerable with most patients completing treatment within the planned OTT. When unplanned gaps occur, then compensation by further acceleration is possible.
A New Focus on Supervision: Looking to the Future
Authors: O’Connor Lisa Cabiale 
Published: March 2008

Abstract
This article examines some of our assumptions about clinical supervision, such as, good clinicians automatically make good supervisors, the major role of the supervisor is evaluation, and formal education is not necessary for engaging in supervision. It is important to examine what actions or future directions are necessary so that we do more than just say we recognize supervision as a distinct area of practice. It is time to identify actions professionals and/or the professions need to take in order to ensure quality supervision and, as a result, more effective clinical education. Suggestions include, among others, focusing on increased knowledge and understanding of the supervisory process in speech-language pathology and audiology, acknowledging that education in supervision makes a difference and creates opportunities for professionals to obtain such education, developing and distributing new professional policy documents that focus on supervision, recognizing and promoting a comprehensive definition of the supervisory process, developing tools to evaluate the effectiveness of supervisors, and promoting research that supports the efficacy of supervision in the professions. Supervision is necessary; it is guided by competencies that require training; it is both an art and a science; and, it is a specialty area of the professions.
Identification and Remediation of At-Risk Student Clinicians in Audiology and Speech-Language Pathology
Authors: Wilson Martha Wilder , Zylla-Jones Elizabeth 
Published: March 2008

Abstract
The goal of university training programs is to educate speech-language pathology and audiology students to become competent and independent practitioners, with the ability to provide high quality and professional services to the public. This article describes the behaviors of “at-risk” student clinicians, so they may be identified early in their practica and remediation may be implemented. The importance of establishing a student at-risk protocol is discussed as well as a remediation plan for these students. This article summarized the Auburn University Speech and Hearing Clinic’s Student At-Risk Protocol, which may serve as a model for university training programs. The challenges of implementing such a protocol are also discussed.

Authors: Faircloth Susan C. , Pfeffer Robert 
Published: March 2008

Abstract

Purpose:
The purpose of this article is to provide an overview of an innovative community based participatory based research partnership between a university researcher and a tribal Head Start program. This initiative is aimed at improving communicative competence of young Indigenous children while simultaneously decreasing challenging behaviors.

Method:
The use of community based participatory research is presented as a potential model that speech-language pathologists might follow in developing and implementing interventions when working with indigenous children and families. The article includes recommendations for working collaboratively with schools, early education providers, and communities using lessons learned from the emerging partnership between a university researcher and a tribal Head Start program. Recommendations are made regarding the modification and, when appropriate, the development of speech-language interventions aimed at improving communicative competence, emergent literacy, and social and emotional behavior in both therapeutic and home environments.

Conclusion:
This article is useful for speech-language pathologists who are working to develop and implement culturally and linguistically appropriate speech-language interventions for use in early childhood education and home-based programs in Indigenous communities.
Avoiding a Due Process Hearing
Authors: Kreb Roberta 
Published: March 2008

Abstract
The Individuals with Disabilities Education Act (IDEA) provides a framework for ensuring students receiving special education and related services receive a free and appropriate education. When provision of that education is called into question, speech-language pathologists may find themselves involved in a due process hearing. By maintaining solid documentation of services provided and being clear communicators, speech-language pathologists will be prepared for a due process hearing.
Coding for Evaluation and Treatment
Authors: Kander Mark , White Steve 
Published: March 2008

Abstract

This article explains the development and use of ICD-9-CM diagnosis codes, CPT procedure codes, and HCPCS supply/device codes. Examples of appropriate coding combinations, and Coding rules adopted by most third party payers are given. Additionally, references for complete code lists on the Web and a list of voice-related CPT code edits are included. The reader is given adequate information to report an evaluation or treatment session with accurate diagnosis, procedure, and supply/device codes. Speech-language pathologists can accurately code services when given adequate resources and rules and are encouraged to insert relevant codes in the medical record rather than depend on billing personnel to accurately provide this information.
