[Review of] E. San Juan, Jr. From Exile to Diaspora: Versions of the Filipino Experience in the U.S.

The author has written an excellent summary of the little known events in Filipino history in the Philippines and the history of the Filipino community in the U.S., a history of over four hundred years that covers the colonial oppression, and resistance first to Spain and then the United States. He attributes the fractured Filipino identity, one that is fissured by ambivalence, opportunism, and schizoid loyalties, to the colonial experiences under these two western European powers. In his brilliant analysis of the literature he uses a historical materialist theoretical framework (22)

Phase-resolved Photoacoustic Spectroscopy And Epr Investigation Of Mno2- And Coo-doped Soda-lime Glasses

A discussion on the use of the phase shifts of the photoacoustic signal of different constituents of a composite sample for resolving their individual spectra is presented. It is experimentally shown that as long as we are interested in a qualitative analysis the method is simple and fast. For a quantitative analysis in which the nonradiative relaxation time and the characteristic diffusion time within the optical-absorption depth are sought, the method presents some limitations. This is demonstrated using MnO2- and CoO-doped soda-lime silica glass samples. © 1989 The American Physical Society.40318801884CAS; Chinese Academy of Sciences; DFG; Chinese Academy of Sciences; NRF; Chinese Academy of Sciences; NSFC; Chinese Academy of Sciences; PSI; Chinese Academy of Sciences; RAS; Chinese Academy of Sciences; RFBR; Chinese Academy of Sciences; RPF; Chinese Academy of Sciences; STFC; Chinese Academy of Science

Photoacoustic And Esr Studies Of Iron-doped Soda-lime Glasses: Thermal Diffusivity

The photoacoustic technique is used to measure the thermal diffusivity of iron-doped soda-lime glasses. To explain the thermal diffusivity behavior as a function of the iron content in the samples, electron-spin-resonance data were used. It is concluded that the main reason for the observed changes in the thermal diffusivity is the ferric ion entering substitutionally at the Si4+ sites. © 1989 The American Physical Society.40117912791

Laparoscopic Upper-pole Nephroureterectomy In Infants

Objective: Report the results of laparoscopic upper-pole nephroureterectomy in infants. Materials and Methods: Six consecutive infants underwent 7 laparoscopic upper-pole nephroureterectomy. Pre and post-operative evaluation included renal sonography, voiding cystourethrogram and renal scintigraphy. All infants showed upper-pole exclusion. Surgery was performed through a transperitoneal approach with full flank position in all infants. Three or 4 ports were used according to the necessity of retracting the liver. The distal ureter was ligated close to the bladder whenever reflux was present and the dysplastic upper-pole was divided with the help of an electrocautery. Data regarding operative time, postoperative use of analgesics, time to resume oral feeding, hospital stay and tubular function were collected and analyzed. Results: All procedures were concluded as planned. Mean operative time was 135 min. One patient underwent staged bilateral upper-pole nephrectomy. There were no complications and the postoperative hospital stay was 48 hours in 5 procedures and 24 hours in 2 procedures. Pain medication was required only in the first day. Renal tubular function showed improvement in half of the cases. Conclusion: Laparoscopic partial nephrectomy is a safe and feasible procedure in infants. Due to the magnification provided by the lenses, a better vision of the structures is achieved, facilitating selective dissection of vascular upper-pole, renal parenchyma and distal ureter. This approach is less damaging to the lower pole, and is associated to low morbidity and a short hospital stay.3318791Peters, C.A., Laparoscopic and robotic approach to genitourinary anomalies in children (2004) Urol Clin North Am, 31, pp. 595-605Robinson, B.C., Snow, B.W., Cartwright, P.C., De Vries, C.R., Hamilton, B.D., Anderson, J.B., Comparison of laparoscopic versus open partial nephrectomy in a pediatric series (2003) J Urol, 169, pp. 638-640Steyaert, H., Valla, J.S., Minimally invasive urologic surgery in children: An overview of what can be done (2005) Eur J Pediatr Surg, 15, pp. 307-313Koyle, M.A., Woo, H.H., Kavoussi, L.R., Laparoscopic nephrectomy in the first year of life (1993) J Pediatr Surg, 28, pp. 693-695Valla, J.S., Breaud, J., Carfagna, L., Tursini, S., Steyaert, H., Treatment of ureterocele on duplex ureter: Upper pole nephrectomy by retroperitoneoscopy in children based on a series of 24 cases (2003) Eur Urol, 43, pp. 426-429Jordan, G.H., Winslow, B.H., Laparoendoscopic upper pole partial nephrectomy with ureterectomy (1993) J Urol, 150, pp. 940-943Horowitz, M., Shah, S.M., Ferzli, G., Syad, P.I., Glassberg, K.I., Laparoscopic partial upper pole nephrectomy in infants and children (2001) BJU Int, 87, pp. 514-516Gill, I.S., Delworth, M.G., Munch, L.C., Laparoscopic retroperitoneal partial nephrectomy (1994) J Urol, 152, pp. 1539-1542Borzi, P.A., A comparison of the lateral and posterior retroperitoneoscopic approach for complete and partial nephroureterectomy in children (2001) BJU Int, 87, pp. 517-520Desgrandchamps, F., Gossot, D., Jabbour, M.E., Meria, P., Teillac, P., Le Duc, A., A 3 trocar technique for transperitoneal laparoscopic nephrectomy (1999) J Urol, 161, pp. 1530-1532Hulbert, W.C., Rabinowitz, R., Prenatal diagnosis of duplex system hydronephrosis: Effect on renal salvage (1998) Urology, 51, pp. 23-26El-Ghoneimi, A., Farhat, W., Bolduc, S., Bagli, D., McLorie, G., Khoury, A., Retroperitoneal laparoscopic vs open partial nephroureterectomy in children (2003) BJU Int, 91, pp. 532-535Jednak, R., Kryger, J.V., Barthold, J.S., Gonzalez, R., A simplified technique of upper pole heminephrectomy for duplex kidney (2000) J Urol, 164, pp. 1326-1328Borzi, P.A., Yeung, C.K., Selective approach for transperitoneal and extraperitoneal endoscopic nephrectomy in children (2004) J Urol, 171, pp. 814-816Guillonneau, B., Ballanger, P., Lugagne, P.M., Valla, J.S., Vallancien, G., Laparoscopic versus lumboscopic nephrectomy (1996) Eur Urol, 29, pp. 288-291Janetschek, G., Seibold, J., Radmayr, C., Bartsch, G., Laparoscopic heminephroureterectomy in pediatric patients (1997) J Urol, 158, pp. 1928-193

Part of the message comes in gesture: how people with aphasia convey information in different gesture types as compared with information in their speech

Background: Studies have shown that the gestures produced by people with aphasia (PWA) can convey information useful for their communication. However, the exact significance of the contribution to message communication via gesture remains unclear. Furthermore, it remains unclear how different gesture types and representation techniques impact message conveyance. Aims: The present study aimed to investigate the contribution of gesture to PWA’s communication. We specifically focussed on the degree to which different gesture types and representation techniques convey information absent in the speech of PWA. Methods & Procedure: We studied the gestures produced by 46 PWA and nine non-brain-damaged participants (NBDP) during semi-structured conversation. For each of the different types of gestures and representation techniques we identified whether these conveyed essential information, that is information that was absent in speech. Rather than looking at information that was either similar to information in speech or additional to information in speech, we focused on the essential gestures only. Outcomes & Results: For PWA, a fifth of their gestures were Essential. Despite individual differences between PWA, the majority produced more Essential gestures than NBDP, who produced limited amounts of Essential gestures. Essential information was mostly conveyed by specific gesture types: Pointing, Emblems and Iconic gesture. Within the group of iconic gestures, not only Handling and Enact but also Object and Shape gestures, were often Essential. Conclusions: Our findings suggest that a great proportion of gestures produced by most PWA convey information essential for understanding their communication. In their communication advice, speech language therapists could draw attention to specific gesture types to make sure that interlocutors pay more attention to these gestures when communicating with PWA

Time-resolved kinetic assessment of the role of singlet and triplet excited states in the photocatalytic treatment of pollutants at different concentrations

[EN] A kinetic-based rationale to assess the role of each excited species in thermodynamically favoured photocatalytic processes at different pollutant concentrations, has been developed and illustrated with new experimental data. Specifically, 2,4,6-triphenylthiapyrylium (TPTP+) salt has been chosen as a representative organic compound capable to act as photocatalyst, and the possible involvement of its excited states in the photodegradation of pollutants commonly found in aqueous ecosystems has been investigated using five chemicals, namely acetaminophen, acetamiprid, caffeine, clofibric acid and carbamazepine. First, steady-state photolysis has been carried out under simulated solar irradiation in the presence of TPTP+, and second, photophysical measurements (fluorescence and laser flash photolysis) have been performed in order to obtain reliable fast kinetic data. Thermodynamic considerations allow ruling out energy transfer processes, while the kinetic results are in good agreement with an electron transfer to the triplet excited state of TPTP+. Hence, the higher the intersystem crossing quantum yield the better. Although quenching of the singlet excited state is also observed, the contribution of this reactive species is only minor, due to its shorter lifetime. In general, the efficiency of a photocatalyst should be enhanced at higher pollutant concentrations, at which the intrinsic decay of the triplet excited state is minimized. (C) 2016 Elsevier B.V.

Horizontes da Avaliação em Tecnologias da Saúde

Tomando como pano de fundo as recomendações da International Network of Agencies for Health Technology Assessment (INAHTA) e as propostas de trabalho do Danish Centre of Health Technology Assessment - National Board of Health, os autores colocam em ênfase que a avaliação em tecnologias da saúde (ATS) é um campo de estudos multidisciplinares, cujos resultados comportam diversas implicações clínicas, sociais, culturais, políticas, éticas e económicas no domínio do desenvolvimento, difusão e utilização das tecnologias na prestação dos cuidados de saúde. Refutando a mera ideia de que a ATS seja um veículo instrumentalizado para fornecer aos decisores políticos informações sobre os possíveis impactos e as consequências de uma nova tecnologia nos cuidados de saúde, os autores argumentam que é necessário refletir e debater sobre os critérios de ATS, sugerindo para o efeito a adoção dum modelo plural e multidisciplinar do tipo do modelo dinamarquês, tendo o cidadão-utente no centro do sistema de avaliação em tecnologias da saúde

Spin effects in intramolecular electron transfer in naproxen-N-methylpyrrolidine dyad

[EN] The intramolecular electron transfer in the naproxen-N-methylpyrrolidine dyad has been investigated by spin chemistry methods. The existence of CIDNP in a high magnetic field points to electron transfer as a possible mechanism of the quenching of the excited state of a dyad. However, the failure to detect magnetic field effects on triplet yield makes us conclude that this quenching mechanism is not the only one. The observation of CIDNP effects in the dyad in the media of low polarity and the short risetime of triplet state formation indicate a potential role of exciplex in the quenching of the excited state of the dyad.This work was supported by the Grants 08-03-00372 and 11-03-01104 of Russian Foundation of Basic Research, and the grant of Priority Programs of RAS, No. 5.1.5.Magin, I.; Polyakov, N.; Khramtsova, E.; Kruppa, A.; Tsentalovich, Y.; Leshina, T.; Miranda Alonso, MÁ....
