Reexamination of Electron Mobility Dependence on Dopants in GaAs

The influence of dopant species on electron mobility in GaAs is investigated. Based on Thomas-Fermi theory to describe the charge density of the individual impurity ion we derive an analytical expression for the scattering rate. Employing these results in a Monte Carlo calculation we fi nda signifi cantdependence of mobility on donor species for concentrations beyond cm . With increasing concentration an increasing difference is observed, ions with larger atomic number lead to lower mobility values. In case of minority electron mobility no signifi cantdopant dependence is predicted.
Synthesis of Multilayer WAIM Coatings for Planar-Phased Arrays Within the System-by-Design Framework

The synthesis of multilayer wide-angle impedance-matching (WAIM) structures for waveguide-fed planar phased array antennas is addressed. Under multifrequency constraints and assuming arbitrary array layouts, the synthesis problem is formulated within the system-by-design (SbD) framework. An iterative strategy is implemented by combining a fast EM modeling tool for the computation of the voltage reflection coefficient at the array surface and a solution-space sampling loop driven by the set of physical constraints describing both the synthesis objectives and the range boundaries for the degrees-of-freedom (DoFs) of the problem at hand. Thanks to the effectiveness and the reliability of such an integrated approach, it is possible to deal with multilayer multifrequency WAIM structures with uniaxially anisotropic permittivity and permeability tensors. Selected numerical results are presented to assess the potentialities and the reliability of the proposed approach also in comparison with state-of-the-art techniques.
Morfoanatomia do Embrião, Desenvolvimento Pós-Seminal e Origem do Rizóforo de Smilax quinquenervia Vell. (Smilacaceae)

Um estudo do desenvolvimento pos-seminal de Smilax quinquenerviaVell. demonstrou o aparecimento de um eixo embrionario do qual se desenvolvem a plumula e a raiz primaria apos o que, distingue-se o hipocotilo. A plumula origina um eixo primario formado por 3 a 4 nos (cada um, com um catafilo), que precede o aparecimento do eofilo. Do hipocotilo saem as primeiras raizes adventicias. Do no cotiledonar, a partir de uma gema protegida pela bainha cotiledonar, surge um eixo caulinar que permanece subterrâneo, o rizoforo, que passa a formar uma grande quantidade de raizes adventicias. Esse rizoforo e um sistema de ramificacao simpodial. A grande quantidade de estomatos presentes na epiderme do rizoforo poderia representar uma evidencia desse orgao subterrâneo ter derivado de um orgao ancestral aereo.
Positive affect and disability among older Mexican Americans with arthritis.

OBJECTIVE To examine the relationship between positive affect and subsequent functional disability in older Mexican Americans with self-reported physician-diagnosed arthritis. METHODS We conducted a 2-year prospective cohort study using a population-based sample of 1,084 noninstitutionalized Mexican American subjects aged > or =65 years residing in 5 southwestern states. Measures included self-reported diagnoses of various medical conditions, functional ability, body mass index, and ratings of positive and negative affect. RESULTS For 937 subjects with arthritis who reported no limitations in activities of daily living (ADLs) at baseline, 697 remained ADL independent, 84 became ADL dependent, 41 died, and 115 were lost to followup 2 years later. There was a significant association between high positive affect (score = 12) and reduced risk of ADL disability 2 years later, controlling for baseline sociodemographic variables, medical conditions, and negative affect (odds ratio 0.46, 95% confidence interval 0.22-0.94). There was an interaction effect between positive affect and sex, with positive affect having a larger effect in reducing risk of ADL dependence in men than in women. CONCLUSION High positive affect was associated with lower incidence of ADL disability in older Mexican Americans with self-reported physician-diagnosed arthritis. The strength of the positive affect is stronger in men than in women.
Efficacy and safety of etravirine in treatment-experienced, HIV-1 patients: pooled 48 week analysis of two randomized, controlled trials

Objective:To evaluate the efficacy, safety and virologic resistance profile of etravirine (TMC125), a next-generation nonnucleoside reverse transcriptase inhibitor, over 48 weeks in treatment-experienced adults infected with HIV-1 strains resistant to a nonnucleoside reverse transcriptase inhibitor and other antiretrovirals. Design:DUET-1 (NCT00254046) and DUET-2 (NCT00255099) are two identically designed, randomized, double-blind phase III trials. Methods:Patients received twice-daily etravirine 200 mg or placebo, each plus a background regimen of darunavir/ritonavir, investigator-selected nucleoside/nucleotide reverse transcriptase inhibitors and optional enfuvirtide. Eligible patients had documented nonnucleoside reverse transcriptase inhibitor resistance, at least three primary protease inhibitor mutations at screening and were on a stable but virologically failing regimen for at least 8 weeks, with plasma viral load more than 5000 copies/ml. Pooled 48-week data from the two trials are presented. Results:Patients (1203) were randomized and treated (n = 599, etravirine; n = 604, placebo). Significantly more patients in the etravirine than in the placebo group achieved viral load less than 50 copies/ml at week 48 (61 vs. 40%, respectively; P < 0.0001). Significantly fewer patients in the etravirine group experienced at least one confirmed or probable AIDS-defining illness/death (6 vs. 10%; P = 0.0408). Safety and tolerability in the etravirine group was comparable to the placebo group. Rash was the only adverse event to occur at a significantly higher incidence in the etravirine group (19 vs. 11%, respectively, P < 0.0001), occurring primarily in the second week of treatment. Conclusion:At 48 weeks, treatment-experienced patients receiving etravirine plus background regimen had statistically superior and durable virologic responses (viral load less than 50 copies/ml) than those receiving placebo plus background regimen, with comparable tolerability and no new safety signals reported since week 24.
The Gallbladder of the Electric Ray Torpedo Marmorata Risso Displays Excrescent Cholecystocytes with Merocrine and Apocrine‐Like Secretions

The gallbladder of Torpedo marmorata exhibits a mucosal surface layer of simple columnar epithelium with very tall cholecystocytes. The apical domain of each cell has few microvilli, but many mucous vesicles that are secreted by exocytosis at the cell apices. The apical regions may also elongate and undergo self‐excision while shedding mucus and cell debris into the gallbladder lumen in a manner similar to that described in mammals as a result of sex steroid treatment to induce gallstones and to that found in the cholecystitis associated with cholelithiasis. Numerous small mitochondria, spherical to elongated, are distributed throughout the cells, while the nuclei are often located in the lower third of each cell. In the lower part of the cholecystocytes, large and very densely contrasted lysosomes can be found. All cells are tightly joined by junctional complexes, including long, highly contrasted desmosomes. The fibromuscular layer is made of a loose stroma with a limited muscular component and a poor blood supply. Large diameter blood vessels can only be found in the subserosal layer. It is hypothesized that the obligatorily carnivorous diet of this ureotelic fish has resulted in the evolution of a gallbladder ultrastructure resembling that found in cholecystitis but without the associated cholelithiasis.

SME eBusiness Readiness in Five Eastern European Countries: Results of a Survey

We report initial findings from a survey conducted to determine the state of ebusiness readiness by SMEs in five Eastern European countries. The work is part of the EU-sponsored project ENLARGE. A questionnaire was administered in late 2001 to over 900 executives and managers from SMEs in Poland, Slovenia, Romania, Bulgaria, and Cyprus. The survey looked at e-business readiness by exploring three levels of analysis: the company and organizational level, the market and industry level, and the national and regulatory level. Initial results from this rich and recent dataset suggest a fairly strong adoption of basic technical infrastructure, such as PCs, Internet access, and company Web site. Exploitation of these technologies is more limited and varies across the different countries. At the 1 This paper is based on work performed for the EU sponsored project, ENLARGE. We thank the consortium members who coordinated the data collection efforts in each country: Uros Hribar at University of Maribor, Vladimir Lazarov and Nina Tasheva at Bulgarian Academy of Sciences, Andry Marangos and George Samaras at University of Cyprus, Ana-Maria Borozan and Ileana Trandafir at ICI in Romania, and Witold Bielecki at LKAEM in Poland.

Finally, at the national and regulatory level, respondents believe that there is little support from their regional and national governments, and that more maturity is needed in the technical, business, and social infrastructure.
Heterogeneity, persistence, and distribution of Pseudomonas aeruginosa genotypes in cystic fibrosis patients

A collection of 222 isolates of Pseudomonas aeruginosa was obtained from the respiratory tract of 16 patients with cystic fibrosis over a 4- to 9-month period. Fourteen of these patients were unrelated, while the remaining two were siblings. Isolates were typed by conventional pyocin typing and also by the use of a DNA probe containing 741 bp immediately upstream of the exotoxin A structural gene and the initial 732 bp of the exotoxin A structural gene. By pyocin typing, 69% (11 of 16) of the patients were shown to harbor a single type that persisted in the lung throughout the study. By genotyping (DNA probe typing), all but three patients (13 of 16, 81%) harbored a single persistent genotype in their lungs. Six patients other than the sibling pair (6 of 14, 43%) shared a common genotype in their lungs as judged by DNA probing, and the pyocin type of these isolates was also identical. In four of these six patients, the shared genotype was also the persistent genotype. The sibling pair studied also carried a common genotype in their lungs as indicated by DNA probing, even though the pyocin type of these isolates varied. Results presented suggest that the majority of patients harbor a persistent strain in their lungs and that cross-colonization may occur.
Generalized approach to the regulation and integration of gene expression

The volume of electron flow through the cbb3 branch of the electron transport chain and the redox state of the quinone pool generate signals that regulate photosynthesis gene expression in Rhodobacter sphaeroides. An inhibitory signal is generated at the level of the catalytic subunit of the cbb3 cytochrome c oxidase and is transduced through the membrane‐localized PrrC polypeptide to the PrrBA two‐component activation system, which controls the expression of most of the photosynthesis genes in response to O2. The redox state of the quinone pool is monitored by the redox‐active AppA antirepressor protein, which determines the functional state of the PpsR repressor protein. The antirepressor/repressor system as well as a modulator of AppA function, TspO, together with FnrL and PrrA stringently control photopigment gene expression. These regulatory elements, together with spectral complex‐specific assembly factors, control the ultimate cellular levels and composition of the photosynthetic membrane.
The development of psychoanalytic parent–infant/child psychotherapy in South Africa: Adaptive responses to contextual challenges

South African authored writings on psychoanalytically-informed parent–infant/child psychotherapy are rare, but this dearth does not accurately reflect the extent of practice in the country at the community, public and private levels. Interviews with a sample of key stakeholders and practitioners provided information on different services currently offered in the South African parent–infant/child psychotherapy field. Three major themes were identified during an analysis of interview material: the role of language and culture; the issue of training; and the challenge of working outside of a national health system. Interviewees also described adaptive responses to these contextual challenges. These responses are discussed as evidence of the usefulness of theoretical and technical eclecticism, when applied with psychoanalytic mindfulness, in developing the South African parent–infant/child psychotherapy field.
Rapid Recovery With Oral Zinc Sulphate in Deferoxamine-induced Presumed Optic Neuropathy and Hearing Loss

Deferoxamine continues to be the mainstay of therapy to remove excess iron in patients requiring long-term transfusions. Overall, deferoxamine has been regarded as having minimal side effects. However, neurotoxicityrelated abnormalities, such as optic neuropathy and sensorineural hearing loss, have been described in patients receiving long-term high-dose subcutaneous deferoxamine (1–3). Management of deferoxamine toxicity consists of immediate drug withdrawal. Reversal of toxicity takes weeks to months and does not appear to be related to the deferoxamine dosage and the patient’s age. We report a case of deferoxamine-induced presumed optic neuropathy and sensorineural hearing loss. The patient recovered rapidly after treatment with oral zinc sulphate.
Bioconversion of wastes from olive oil industries by vermicomposting process using the epigeic earthworm Eisenia andrei

The present work evaluates the possible bioconversion of wet olive cake by low-cost biostabilization (vermicomposting process). Wet olive cake fresh (WOC), precomposted (WOCP), or mixed with biosolids (WOCB), were vermicomposted for 6 months to obtain organic amendments for agricultural and remediation purposes. The results showed initial differences depending on previous treatment. WOCP was initially more stable, presented a low C:N ratio, and showed more dehydrogenase and urease activity. By contrast, there was no dehydrogenase activity initially in WOC and WOCB, due to the presence of some different types of polyphenols. Finally, the end product showed relatively higher amounts of total nitrogen and humic acid and met the standard of quality for composts and vermicomposts for use both in conventional and organic agriculture and soil-restoration programs.
Critical care nurse work environments 2013: a status report.

BACKGROUND The health of critical care nurse work environments has been shown to affect patient care outcomes as well as the job satisfaction and retention of registered nurses. The American Association of Critical-Care Nurses (AACN) Critical Care Nurse Work Environment Survey was first conducted in 2006 following the release of the AACN Standards for Establishing and Sustaining a Healthy Work Environment and was conducted again in 2008. This article reports the results of the third AACN Critical Care Nurse Work Environment Survey conducted in 2013. OBJECTIVE To evaluate the current state of critical care nurse work environments. METHODS A total of 8444 AACN members and constituents responded to an online survey. RESULTS The overall health of critical care nurses' work environments has declined since 2008, as have nurses' perceptions of the quality of care. Respondents rated their overall work environment and factors associated with healthy work environments including quality of patient care, staffing, communication and collaboration, respect, physical and mental safety, moral distress, nursing leadership, support for certification and continuing education, meaningful recognition, job satisfaction, and career plans. Although some factors improved, declines in any factors are a concern. CONCLUSIONS An increasing body of evidence has shown relationships between healthy nurse work environments and patient outcomes. The results of this 2013 survey identified areas in which the health of critical care nurse work environments needs attention and care, requiring the relentless true collaboration of everyone involved.

Audiovisual temporal discrimination is less efficient with aging: an event-related potential study

We investigated the crossmodal temporal discrimination deficit characterizing older adults and its event-related potential (electroencephalogram) correlates using an audiovisual temporal order judgment task. Audiovisual stimuli were presented at stimulus onset asynchronies (SOA) of 70 or 270 ms. Older were less accurate than younger adults with an SOA of 270 ms but not 70 ms. With an SOA of 270 ms only, older adults had smaller posterior P1 and frontocentral N1 amplitudes for visual stimuli in auditory–visual trials and auditory stimuli in visual–auditory trials, respectively. These results suggest a deficit in cross-sensory processing with aging reflected at the behavioural and neural level, and suggest an impairment in switching between modalities even when the inputs are separated by long temporal intervals.
Mujeres y deporte en los medios de comunicación : estudio de la prensa deportiva española (1979-2010)

Mujeres y deporte en los medios de comunicacion. Estudio de la prensa deportiva espanola (1979? 2010)? responde a la necesidad de saber y probar que, pese a la gran demanda de informacion deportiva en los medios, pese a que parece haberse trasladado en el imaginario colectivo la idea de la equiparacion de derechos hombre / mujer y la incorporacion plena de la mujer al mundo del deporte, la realidad es otra. La informacion deportiva en Espana y la presencia de las mujeres en los medios de comunicacion son dos ambitos de enorme complejidad como fenomenos sociales contemporaneos. El presente trabajo viene a llenar un vacio, desde la perspectiva de la informacion periodistica y se centra en los elementos de significacion de contenidos y en el mensaje mismo. Tiene como finalidad principal analizar la informacion deportiva en la prensa espanola, acometiendo una reflexion sobre el periodismo deportivo espanol en los ultimos anos, su evolucion, contenidos, etc. Y, en concreto, estudiar la presencia de las mujeres como tema, como fuente y como autora de la misma, prestando especial atencion a la evolucion de su figura, imagen y concepcion de los ultimos anos. Para ello, mediante un diseno ? Ex Pos Facto? y la metodologia observacional se analizaran todas las informaciones de los cuatro diarios deportivos de pago con mayor audiencia y mayor tirada nacional: Marca y As, editados en Madrid y, Mundo Deportivo y Sport, editados en Barcelona. Mediante un muestreo aleatorio, se han analizado todas las informaciones de prensa deportiva de los periodicos Marca, As, Mundo Deportivo y Sport, que se publicaron durante una semana de duracion desde el ano 1979 hasta el ano 2010. Se han analizado, por tanto, un total de 4 periodicos x 32 semanas x 7 dias, es decir 896 periodicos, con un total de 95.439 informaciones. Para ello, y siguiendo la propuesta de Perez (2009), se escogio mediante un muestreo aleatorio simple un numero de semana al ano (52 semanas al ano, 56 en los anos bisiestos) y un dia de la semana, registrando todas las informaciones desde ese dia de la semana hasta el dia anterior de la semana siguiente. El objetivo principal es presentar y analizar la imagen que de las deportistas se refleja en los medios de comunicacion deportivos. La hipotesis de partida es: ? La imagen de las mujeres que los medios de comunicacion espanoles -en concreto la prensa deportiva- transmiten a la sociedad esta desequilibrada y estereotipada?
The sleep of depressed patients. An EEG and eye movement study.

Introduction IT IS A common clinical impression that depressed patients obtain less sleep, experience early morning awakening, and complain of less restful sleep. Diaz-Guerrero et al 5 studied the sleep of six manic-depressive psychotics, depressive type, by recording their all-night electroencephalogram (EEG). They report that, after excluding the waking record time, the patients had twice as much low voltage recording of light sleep as controls, half as much spindles plus random, and more sleep depth changes. Oswald et al 7 studied the effect of heptabarbital on six depressed patients and six controls by recording for each the all-night EEG and electro-oculogram (EOG) for four successive nights. The drug was administered in 400 mg doses on two of the four nights. They report no abnormality in the sleep which was characteristic of this group of depressed patients other than excessive wakefulness, which was equally
Smokers and non smokers with rheumatoid arthritis have similar clinical status: data from the multinational QUEST-RA database.

OBJECTIVES To analyse clinical severity/activity of rheumatoid arthritis (RA) according to smoking status. METHODS The QUEST-RA multinational database reviews patients for Core Data Set measures including 28 swollen and tender joint count, physician global estimate, erythrocyte sedimentation rate (ESR), HAQ-function, pain, and patient global estimate, as well as DAS28, rheumatoid factor (RF), nodules, erosions and number of DMARDs were recorded. Smoking status was assessed by self-report as 'never smoked', 'currently smoking' and 'former smokers'. Patient groups with different smoking status were compared for demographic and RA measures. RESULTS Among the 7,307 patients with smoking data available, status as 'never smoked,' 'current smoker' and 'former smoker' were reported by 65%, 15% and 20%. Ever smokers were more likely to be RF-positive (OR 1.32;1.17-1.48, p<0.001). Rheumatoid nodules were more frequent in ever smokers (OR 1.41;1.24-1.59, p<0.001). The percentage of patients with erosive arthritis and extra-articular disease was similar in all smoking categories. Mean DAS28 was 4.4 (SD 1.6) in non-smokers vs. 4.0 (SD 1.6) in those who had ever smoked. However, when adjusted by age, sex, disease duration, and country gross domestic product, only ESR remained significantly different among Core Data Set measures (mean 31.7mm in non-smokers vs. 26.8mm in ever smoked category). CONCLUSIONS RA patients who had ever smoked were more likely to have RF and nodules, but values for other clinical status measures were similar in all smoking categories (never smoked, current smokers and former smokers).
Theiler's Virus L* Protein Is Targeted to the Mitochondrial Outer Membrane

ABSTRACT The L* protein encoded by Theiler's murine encephalomyelitis virus (TMEV) is a unique example of a picornaviral protein encoded by an alternative open reading frame. This protein is an important determinant of TMEV persistence in the mouse central nervous system. We showed that in infected cells, L* is partitioned between the cytosol and the mitochondria. In mitochondria, L* is anchored in the outer membrane and exposed to the cytosol. The targeting of L* to mitochondria is independent of other viral components and likely depends on a conformational signal. L* targeting to mitochondria might involve chaperones of the Hsp70 family, as these proteins are shown to interact.
