    Embodied Conversational Agents (ECA) are poised to constitute a specific category within persuasive systems, in particular through their ability to support affective dialogue. One possible approach consists in using ECA as virtual coaches or personal assistants and to make persuasion part of a dialogue game implementing specific argumentation or negotiation features. In this paper, we explore an alternative framework, which emerges from the long-term development of ECA as "Companions" supporting free conversation with the user, rather than task-oriented dialogue. Our system aims at influencing user attitudes as part of free conversation, albeit on a limited set of topics. We describe the implementation of a Companion ECA to which the user reports on his working day, and which can assess the user's emotional attitude towards daily events in the office, trying to influence such attitude using affective strategies derived from a narrative model. This discussion is illustrated through examples from a first fully-implemented prototype.

    2011-09-01

    Full Text Available Lately, a growing volume of research has been conducted on studying the effects of equal channel angular extrusion processing. Equal channel angular extrusion (ECAE or equal channel angular pressing (ECAP is a severe plastic deformation (SPD technique, which presses the test materials through a die with two channels which are equal in cross section and intersecting at a certain angle. After the deformation, the test materials will still retain its original cross-section being able to repeat the process to many cycles. This method improves the mechanical properties of the processed materials because of the ultrafine grained structures resulted. Present paper intends to make a qualitative investigation of the Mg-Zn-Zr samples processed through ECAE.

    2016-05-01

    Equal channel angular extrusion (ECAE) has been studied at the lab scale for many years. However, few successful industrial applications of the ECAE process have been reported. In the present work, a process referred to as Ex-ECAE that was composed of two processes of the direct extrusion and the ECAE via route C, was developed. The Ex-ECAE process was developed to refine the microstructure of the extrudate, particular the coarse grain layer (CGL) on the surface of the extrudate. The Ex-ECAE die with a die angle of 120° contained three segments and was used in the conventional direct extrusion press. The high friction and the continuous routes of the ECAE resulted in asymmetric dead metal zones (DMZs) to be formed at the corners of the die channel. It revealed that the visible grains in the CGL were refined and became invisible due to the intense shear deformation as the CGL flowed along the boundaries of the asymmetric DMZs. The textures of the Ex-ECAE at the various segments were studied by EBSD. This study demonstrated that the ECAE process could be scaled up using the extrusion press. Success or lack of success depended on the capacity of the extrusion press and the die design.

    Mogucheva, A.; Kaibyshev, R.

    2010-07-01

    Fatigue properties and fatigue crack growth rate were examined in an Al-Mg-Li-Sc-Zr allow subjected to equal channel angular extrusion (ECAE) with rectangular shape of channels up to a total strain of ~4 at a temperature of 325°C followed by solution treatment with subsequent oil quenching with aging. After this processing the fraction recrystallized was ~80pct; the deformed microstructure remains essentially unchanged under solution treatment due to high density of Al3Sc coherent dispersoids playing a role of effective pinning agents. It was shown that the fatigue limit of this material attained a value of ~185 MPa. Thermomechanical processing provided a decrease in fatigue crack propagation growth rate and an increase in the stress intensity factor, K1c, in comparison with extruded bar. However, characteristics of crack propagation resistance did not attain values suitable for application of this alloy for critical aircraft components.

    AIM: To investigate the possible role of polysaccharide-K (PSK) -related markers in predicting distant metastasis and in the clinical outcome of colorectal cancer (CRC).METHODS: Firstly, we used protein microarrays to analyze the in vitro expression profiles of potential PSKrelated markers in the human colorectal adenocarcinoma cell line SW480, which carries a mutant p53 gene. Then,we investigated the clinical implications of these markers in the prognosis of CRC patients.RESULTS: ECA39, a direct target of c-Myc, was identified as a candidate protein affected by the anti-metastatic effects of PSK. Immunohistochemistry revealed that ECA39 was expressed at significantly higher levels in tumor tissues with distant metastases compared to those without (P < 0.00001). Positive ECA39 expression was shown to be highly reliable for the prediction of distant metastases (sensitivity: 86.7%, specificity: 90%, positive predictive value: 86.7%, negative predictive value:90%). A significantly higher cumulative 5-yr disease free survival rate was observed in the ECA39-negative patient group (77.3%) compared with the ECA39-positive patient group (25.8%) (P < 0.05).CONCLUSION: Our results suggest that ECA39 is a dominant predictive factor for distant metastasis in patients with advanced CRC and that its suppression by PSK might represent a useful application of immunotherapy as part of a program of integrated medicine.

  7. Innovation Forms and Firm Export Performance: Empirical Evidence from ECA Countries

    Directory of Open Access Journals (Sweden)

    Andrzej Cieślik

    2017-06-01

    Full Text Available Objective: The main objective of this paper is to verify empirically the relationship between various forms of innovation and export performance of firms from European and Central Asian (ECA countries. Research Design & Methods: In our empirical approach we refer to the self-selection hypothesis derived from the Melitz (2003 model which proposed the existence of a positive relationship between firm productivity and the probability of exporting. We argue that innovation activities should be regarded as a key element that can increase the level of firm productivity. We focus our analysis on four forms of innovation activities: product, process, marketing, organizational and managerial innovation. The empirical implementation of our analytical framework is based on the probit model, applied to the fifth edition of the BEEPS firm level dataset covering 2011-2014. Findings: Our empirical results indicate that the probability of exporting is positively related to both product and process innovations. The marketing and managerial innovations do not seem to affect positively export performance of firms from ECA countries. Implications & Recommendations: It is recommended to develop innovation supporting mechanisms that would target both product and process innovations rather than other forms of innovation in the ECA countries. Contribution & Value Added: The originality of this work lies in the use of the multi-country firm level dataset that allows distinguishing between various forms of innovations in the ECA countries.

    We investigated the effects of stathmin 1 (STMN1) silencing by small interfering (siRNA) on the sensitivity of esophageal cancer cells Eca-109 to paclitaxel. STMN1 siRNA was transiently transfected into Eca-109 cells. The effects of transfection were detected by quantitative polymerase chain reaction and western blotting. The effects of STMN1 silencing by siRNA on the sensitivity of esophageal cancer cells Eca-109 to paclitaxel was tested by MTT and colony formation assays. Hoechst 33258 nuclear staining was used to investigate the differences in Eca-109 cell apoptosis induced by paclitaxel. STMN1 siRNA was successfully transfected and the expression of STMN1 was inhibited. The sensitivity of STMN1 siRNA-transfected Eca-109 cells to paclitaxel was significantly increased (P < 0.01). The apoptosis of Eca-109 cells significantly increased following treatment with paclitaxel (P < 0.01). STMN1 silencing by siRNA may enhance the sensitivity of esophageal cancer cells Eca-109 to paclitaxel and induce apoptosis.

Method The effect of kaempferol on Eca-109 cell proliferation in vitro was measured by MTT assay. TUNEL staining was used to detect the cell apoptosis following kaempferol treatment. The changes in Bax and Bcl-2 mRNA expressions in response to kaempferol treatment were determined by RT-PCR, and the caspase-3 and caspase-9 activities were evaluated using colorimetric assay. Results Kaempferol significantly inhibited Eca-109 cell proliferation (P<0.05) in a concentration-dependent manner and induced obvious cell apoptosis. RT-PCR showed that after kaempferol treatment caused up-regulated Bax and down-regulated Bcl-2 mRNA expression. The colorimetric assay revealed significantly increased caspase-3 and caspase-9 activities in Eca-109 cells following kaempferol treatment (P<0.01). Conclusion Kaempferol can induce apoptosis of Eca-109 cells via a mitochondria-dependent pathway.

    Full Text Available La artrosis de muñeca es una patología que se origina generalmente tras una lesión ligamentosa intraósea del carpo, debido a una no unión de fractura de escafoides o después de una fractura articular del radio. Se sabe que la artrosis no mejora ni retrocede, por lo que se debe tener el tratamiento ideal para cada paciente según sus propias necesidades, que van desde el manejo médico (cambios de actividad, inmovilización, AINES o infiltración con corticoides. Cuando falla el tratamiento médico, se pueden realizar procedimientos poco invasivos como la denervación, carpectomía proximal o una artrodesis de cuatro esquinas. En estadios avanzados, sólo se puede proponer una artroplastia o artrodesis total de la muñeca.

    Pannuti, Thomas

    2016-06-01

    We present an analysis of a pointed observation made of the luminous northeastern rim of the Galactic supernova remnant (SNR) W28 (G6.4-0.1) with the Chandra X-ray Observatory. W28 is the archetype for the class of SNRs known as the mixed-morphology SNRs: sources in this class of objects feature a shell-like morphology with a contrasting center-filled X-ray morphology. Almost unique amongst mixed-morphology SNRs, W28 exhibits a luminous northeastern rim which is detected in the X-ray, optical and radio: this rim is also the site of a vigorous interaction between W28 and adjacent molecular clouds, as evidenced by the high concentration of hydroxyl (OH) masers seen at this rim. Our pointed Chandra observation of this rim is the highest angular X-ray observation made of this feature: initial analysis and results will be presented and discussed.

Furthermore, a comparison between the different forged rings is made from ECAE-processed material subjected to different heat treatments, previous to the forging stage. On the other hand, the ring forging process is modelled through the use of finite element simulation in order to improve the die design and to study the force required for the isothermal forging, the damage value, and the strain the material predeformed by ECAE has undergone. With this present research work, it is intended to improve the knowledge about the mechanical properties of nanostructured material and the applicability of this material to industrial processes that allow the manufacturing of functional parts.

    Full Text Available Mobile Guides are mobile applications that provide players with local and location-based services (LBS, such as navigation assistance, where and when they need them most. Advances in mobile technologies in recent years have enabled the gamification of these applications, opening up new opportunities to transfer education and culture through game play. However, adding traditional game elements such as PBLs (points, badges, and leaderboards alone cannot ensure that the intended learning outcomes will be met, as the player’s cognitive resources are shared between the application and the surrounding environment. This distribution of resources prevents players from easily immersing themselves into the educational scenario. Adding artificial conversational characters (ECAs that simulate the social norms found in real-life human-to-human guide scenarios has the potential to address this problem and improve the player’s experience and learning of cultural narratives [1]. Although significant progress has been made towards creating game-like mobile guides with ECAs ([2], [3], there is still a lack of a unified framework that enables researchers and practitioners to investigate the potential effects of such applications to players and how to approach the concepts of player experience, cognitive accessibility and usability in this context. This paper presents a theoretically-well supported research framework consisted of four key components: differences in players, different features of the gamified task, aspects of how the ECA looks, sound or behaves and different mobile environments. Furthermore, it provides based on this framework a working definition of what player experience, cognitive accessibility and usability are in the context of game-like mobile guide applications. Finally, a synthesis of the results of six empirical studies conducted within this research framework is discussed and a series of design guidelines for the effective gamification

    Ship emissions degrade air quality and affect human health, and are increasingly becoming a matter of concern. Sulfur emission control areas (ECA), specific coastal regions where only low-sulfur fuels may be consumed by ocean-going ships, have proven to be useful tools to reduce ship-sourced air pollution along the North American, Canadian, and European North and Baltic Sea coastlines. The present work assesses the environmental and health benefits which would derive from designating an ECA in the Marmara Sea and the Turkish Straits (50 000 ships/year; 23 million inhabitants). Results show evidence that implementing an ECA would be technically viable and that it would reduce ship-sourced PM10 and PM2.5 ambient concentrations in Istanbul by 67%, and SO2 by 90%. The reduction of the air pollution burden on health was quantified as 210 hospital admissions from exposure to PM10, 290 hospital admissions from exposure to SO2, and up to 30 premature deaths annually due to ECA emission controls. Consequently, the designation of an ECA in the Marmara Sea and the Turkish Straits is evaluated as a positive, technically viable and real-world measure to reduce air pollution from ships in Turkey.

    Magnetic stent hyperthermia (MSH) is a novel approach for targeted thermotherapy for esophageal cancer, which is based on the mechanism that inductive heat can be generated by the esophageal stent upon exposure under an alternative magnetic field (AMF). A positive effect of MSH on esophageal cancer has been demonstrated, however, there is no study on the in vitro effects of heating treatment or of the effects of AMF exposure on human esophageal cancer cells. This study aimed to investigate the effect of MSH and of AMF exposure in esophageal cancer cells. Inductive heating characteristics of esophageal stents were assessed by exposing the stents under AMF. A rather rapid temperature rise of the Ni-Ti stent when subjected to AMF exposure was observed and the desired hyperthermic temperature could be controlled by adjusting the field parameter of the AMF. Human esophageal squamous carcinoma (ESCC) ECA-109 cells were divided into four groups: the control group, the water-bath heating group, the MSH group and the AMF exposure group. Hyperthermic temperatures were 43, 48 and 53˚C and the treatment time was in the range of 5-30 min. The MTT assay, apoptotic analysis and TUNEL staining were applied in the current investigation. Exposure of ECA-109 cells under AMF with a field intensity of 50 to 110 kA/m had negligible effect on cell viability, cell necrosis and apoptosis. Hyperthermia had a remarkable inhibitory effect on the cell viability and the effect was dependent on the thermal dose (temperature and time). The optimal thermal dose of MSH for ECA-109 cells was 48˚C for 20-30 min. The study also elucidated that there was a difference in the effects on cell necrosis and apoptosis between the heating mode of water bath and MSH. The data suggest that MSH may have clinical significance for esophageal cancer treatment.

  19. Stiffness-damping matching method of an ECAS system based on LQG control

    A novel method of matching stiffness and continuous variable damping of an ECAS (electronically controlled air suspension) based on LQG (linear quadratic Gaussian) control was proposed to simultaneously improve the road-friendliness and ride comfort of a two-axle school bus. Taking account of the suspension nonlinearities and target-height-dependent variation in suspension characteristics, a stiffness model of the ECAS mounted on the drive axle of the bus was developed based on thermodynamics and the key parameters were obtained through field tests. By determining the proper range of the target height for the ECAS of the fully-loaded bus based on the design requirements of vehicle body bounce frequency, the control algorithm of the target suspension height (i.e., stiffness) was derived according to driving speed and road roughness. Taking account of the nonlinearities of a continuous variable semi-active damper, the damping force was obtained through the subtraction of the air spring force from the optimum integrated suspension force, which was calculated based on LQG control. Finally, a GA (genetic algorithm)-based matching method between stepped variable damping and stiffness was employed as a benchmark to evaluate the effectiveness of the LQG-based matching method. Simulation results indicate that compared with the GA-based matching method, both dynamic tire force and vehicle body vertical acceleration responses are markedly reduced around the vehicle body bounce frequency employing the LQG-based matching method, with peak values of the dynamic tire force PSD (power spectral density) decreased by 73.6%, 60.8%and 71.9%in the three cases, and corresponding reduction are 71.3%, 59.4%and 68.2%for the vehicle body vertical acceleration. A strong robustness to variation of driving speed and road roughness is also observed for the LQG-based matching method.

    The flavonol aglycone isorhamnetin shows anti-proliferative activity in a variety of cancer cells. Previous work, from our laboratory showed that isorhamnetin inhibits the proliferation of human esophageal squamous carcinoma Eca-109 cells in vitro, but only after 72 h of exposure. This led us to propose that isorhamnetin exposure induces a cellular stress response that inhibits the antiproliferative and apoptotic effects of the compound during early exposure. To test this hypothesis, the present study examined the effects of isorhamnetin on Eca-109 cells during the first 72 h of exposure. Cell growth was assessed using the trypan blue exclusion assay, and expression of IκBα, NF-κB/p65, NF-κB/p50, phospho-Akt, Bcl-2, COX-2, Mcl-1, Bax, p53 and Id-1 were analyzed by Western blot. During the first 72 h of exposure, NF-κB/p65 and NF-κB/p50 accumulated in nuclei and expression of COX-2, Bcl-2 and Mcl-1 increased. In contrast, expression of IκBα and Bax fell initially but later increased. Expression of phospho-Akt and p53 showed no detectable change during the first 48 h. Pretreatment with the NF-κB inhibitor MG132 before exposure to isorhamnetin blocked the nuclear accumulation of p50 and p65, thereby inhibiting cell proliferation. These results show that during early exposure of Eca-109 cells to isorhamnetin, the NF-κB signaling pathway is activated and COX-2 expression increases, and this increase in expression partially inhibits isorhamnetin-induced apoptosis. Beyond 72 h of exposure, however, the apoptotic effect of isorhamnetin dominates, leading to inhibition of the NF-κB pathway and of cellular proliferation. These results will need to be taken into account when exploring the use of isorhamnetin against cancer in vivo.

    Isorhamnetin is one member of flavonoid components which has been used in the treatment of heart disease. Recently the in vitro anti-cancer effect of isorhamnetin on human esophageal squamous carcinoma cell line Eca-109 was investigated in our lab. When Eca-109 cells were in vitro exposed to the graded doses of isorhamnetin (0-80 microg/ml) for 48 h, respectively, isorhamnetin exhibited cytostatic effect on the treated cells, with an IC(50) of 40+/-0.08 microg/ml as estimated by MTT assay. Inhibition on proliferation by isorhamnetin was detected by trypan blue exclusion assay, clone formation test, immunocytochemical assay of PCNA and (3)H-thymidine uptake analysis. Cell cycle distribution was measured by FCM. It was found that the viability of Eca-109 cells was significantly hampered by isorhamnetin. Compared with the negative control group, the treated group which was exposed to isorhamnetin had increased population in G(0)/G(1) phase from 74.6 to 84 while had a significant reduction in G(2)/M phase from 11.9 to 5.8. In addition to its cytostatic effect, isorhamnetin also showed stimulatory effect on apoptosis. Typical apoptotic morphology such as condensation and fragmentation of nuclei and blebbing membrane of the apoptotic cells could be observed through transmission electron microscope. Moreover, the sharp increase in apoptosis rate between the control and treated group were detected by FCM from 6.3 to 16.3. To explore the possible molecular mechanisms that underlie the growth inhibition and apoptosis stimulatory effects of isorhamnetin, the expressions of six proliferation- and death-related genes were detected by FCM. Expressions of bcl-2, c-myc and H-ras were downregulated whereas Bax, c-fos and p53 were upregulated. However, the in vivo experiments were required to further confirm the anti-cancer effects of isorhamnetin. In conclusion, isorhamnetin appears to be a potent drug against esophageal cancer due to its in vitro potential to not only inhibit

    The present study investigated the effects of small interfering RNAs (siRNAs) specific to the epidermal growth factor receptor (EGFR) gene, on the radiosensitivity of esophageal squamous cell carcinoma cells. EGFR gene siRNAs (EGFR-siRNA) were introduced into esophageal cancer Eca109 cells using Lipofectamine® 2000. The EGFR messenger (m)RNA expression levels, EGFR protein expression and cell growth were assessed using reverse transcription-polymerase chain reaction analysis, western blot analysis and a Cell Counting Kit-8 (CCK-8), respectively. In addition, colony assays were used to determine the inhibitory effects of X-ray radiation on EGFR-silenced cells. EGFR mRNA and protein levels were reduced in the Eca109 cells transfected with EGFR-siRNA. The relative EGFR mRNA expression levels were reduced to 26.74, 9.52 and 4.61% in Eca109 cells transfected with EGFR-siRNA1, 2 and 3, respectively. These mRNA levels were significantly reduced compared with the those of the control group (42.44%; P34.14% in Eca109 cells transfected with EGFR-siRNA1, 2 and 3, respectively. These protein levels were significantly reduced compared with those of the control group (78.57%; P<0.0001). Transfection with siRNA1 resulted in the greatest reduction in EGFR protein expression, with an inhibition rate of 72.84%. This reduction in EGFR expression inhibited the proliferation of Eca109 cells, which was identified using the CCK-8 assay. The proliferation inhibition ratio was 28.2%. The cells treated with irradiation in addition to EGFR-siRNA, demonstrated reduced radiobiological parameters (D0, Dq and SF2) compared with those of cells treated with irradiation only, with a sensitization enhancing ratio of 1.5. In conclusion, suppression of EGFR expression may enhance the radiosensitivity of esophageal cancer Eca109 cells and therefore may represent a promising approach for future clinical practice.

    The work objective was focused on investigation of deformation behaviour of NiTi-based shape memory alloys with respect to technology of their preparation. Deformation behaviour was assessed by unconventional forming methods, particularly by equal channel angular extrusion (ECAE)-but in combination with preceding rotary forging (swaging). Classical light microscopy, as well as X-ray diffraction, was used for evaluation of structural framework of castings and of material after forming. It was established that the alloy Ni50.6-Ti (at.%) after ECAE and re-crystallisation annealing shows bi-modal distribution of mosaic blocks, i.e. mosaic blocks larger than 10 {mu}m and blocks smaller than 10 {mu}m. For determination of re-crystallisation temperature in deformed materials 7 modes of heat treatment were applied. It was proven that the temperature of 600 deg. C was the starting temperature that initiated re-crystallisation.

    Full Text Available La naturaleza nacional de las historiografías es una limitación a la hora de comprender realidades múltiples, que anteceden a la creación de los estados nacionales y de los discursos historiográficos que también surgen y se justifican con ellos. Una muestra de ello es la biografía de un presonaje que resultó central en la historia popular de la revolución andina por la Independencia, Ildefonso de las Muñecas. De origen vasco, nacido en Tucumán, se hizo jefe revolucionario en Cuzco en 1814 y mantuvo luego alzada la provincia de Larecaja, llamada “republiqueta”, por un largo año después de la derrota de la revolución, influyendo casi míticamente en el imaginario popular del altiplano por mucho tiempo después. Su lucha y su biografía no pueden ser tenidas ni por “argentina”, “boliviana” o “peruana” pues ambas rebasan la limitación impuesta por esa parcelación ideológica de la realidad. La biografía del personaje sirve para revisar la perspectiva que sobre la revolución de la independencia podemos tener en el mundo andino, discutiendo también los discursos nacionalistas.

    Full Text Available The aim of this paper is to give an overview of a recent technique in mechanical processing of materials known as "equal channel angular extrusion" (ECAE. This is an innovative method of microstructure refinement through a very intense plastic deformation by simple shear without significant alterations in material dimensions. The historic origin of the technique is outlined with a description in detail of the process and a macromechanic analysis of the ECAE technique. The advantages of this treatment over other techniques, in order to produce ultra-fine grain materials in bulk samples with the resulting enhacement of its mechanical properties, are analysed, in particular its potential superplastic behaviour. The determining factors of the process and the experimental techniques for the understanding of the microstructure evolution are outlined. Finally, a closely and recently emerged technique related to ECAE, known as "equal channel angular drawing" (ECAD, is studied.

    El objetivo del presente artículo es proyectar una visión de conjunto de la reciente técnica de procesado mecánico de materiales conocida como "extrusión en canal angular constante" (ECAE. Esta técnica es un método novedoso de refinamiento microestructural por deformación plástica muy intensa de un material, mediante cizalladura simple sin alteración práctica de sus dimensiones. Se aborda el origen histórico de la técnica, la descripción del proceso y el análisis macromecánico en detalle de la técnica ECAE. Se analizan sus ventajas sobre otras técnicas, para producir materiales de grano ultrafino en muestras masivas, con la potenciación consiguiente de sus propiedades mecánicas y, en especial, su posible comportamiento superplástico. Se abordan los factores determinantes del proceso y las técnicas experimentales para el seguimiento de la evolución de las microestructuras. Por último, se estudia una técnica estrechamente relacionada con la anterior

The purpose of this study was to investigate the sonoactivity of a novel sensitizer, sinoporphyrin sodium (DVDMS, and its sonotoxicity in an esophageal cancer (ECA-109 cell line. Methods: The fluorescence intensity of DVDMS, hematoporphyrin, protoporphyrin IX, and Photofrin II was detected by fluorescence microscopy and flow cytometry. Generation of singlet oxygen was measured using a 1, 3-diphenylisobenzofuran experiment. A 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide assay was used to examine cell viability. Production of reactive oxygen species (ROS and destabilization of the mitochondrial membrane potential were assessed by flow cytometry. Apoptosis was analyzed using Annexin-PE/7-amino-actinomycin D staining. Confocal microscopy was performed to assess mitochondrial damage and identify release of cytochrome C after treatment. Western blots were used to determine expression of oxidative stress-related and apoptosis-associated protein. Ultrastructural changes in the cell were studied by scanning electron microscopy. Results: DVDMS showed higher autofluorescence intensity and singlet oxygen production efficiency compared with other photosensitizers in both cancerous and normal cells. Compared with hematoporphyrin, DVDMS-mediated SDT was more cytotoxic in ECA-109 cells. Abundant intracellular ROS was found in the SDT groups, and the cytotoxicity

    Full Text Available FUNDAMENTO: O efeito renoprotetor dos inibidores da ECA vem sendo questionado no caso de diminuição do volume circulante efetivo, como na insuficiência cardíaca crônica direita ou biventricular. Objetivo: Detectar os preditores clínicos de agravamento renal na população de pacientes com ICC, caracterizado por dois tipos de regime de dosagem de inibidores da ECA. MÉTODOS: De acordo com um desenho de coorte retrospectiva, seguimos dois grupos de pacientes com ICC - tanto direita quanto biventricular -, todos na classe III da NYHA, tratados com inibidores da ECA (enalapril ou lisinopril, e com fração de ejeção do ventrículo esquerdo (FEVE 10 mg por dia de enalapril ou lisinopril. A disfunção renal agravada (ARD foi definida pelo aumento de Cr > 30% com relação ao segmento basal. O modelo de risco proporcional de Cox foi utilizado para identificar os preditores da ARD entre as seguintes variáveis: os inibidores da ECA com "alta" dosagem, idade, FEVE basal, histórico de repetidas terapias intensivas com diuréticos de alça por via intravenosa (diurético intravenoso, diabete, Cr basal, histórico de hipertensão, pressão arterial sistólica < 100 mmHg. RESULTADOS: Cinquenta e sete pacientes foram recrutados, dos quais 15 foram tratados com inibidor da ECA com dosagem "alta". Durante um seguimento médio de 718 dias, a ARD ocorreu em 17 pacientes (29,8%. Apenas o inibidor da ECA com "alta" dosagem (RR: 12,4681 IC: 2,1614 - 71,9239 p = 0,0050 e Cr basal (RR:1,2344 IC: 1,0414 - 1,4632 p = 0,0157 foi demonstrado ser preditor da ARD. Além disso, demonstrou-se que o inibidor da ECA com dosagens "altas" não previu ARD em ICC sem diurético intravenoso e ICC com diabete. CONCLUSÃO: Na ICC de classe III da NYHA, o inibidor da ECA com "altas" dosagens e um maior Cr basal foi preditor da ARD. A nefrotoxicidade relacionada com inibidores da ECA em "altas" dosagens foi aumentada com o diurético intravenoso, ao passo que, em pacientes com

OBJETIVO: O presente estudo investigou a possível influência da enzima conversora de angiotensina (ECA (I/D sobre a aptidão cardiovascular e o desempenho em corridas de meia-distância por parte de brasileiros jovens do sexo masculino. A validade da previsão de VO2max em relação ao genótipo da ECA também foi analisada. MÉTODOS: Um grupo homogêneo de homens jovens moderadamente ativos foi avaliado em um teste de corrida (V1600 m; m.min-1 e em um teste adicional em esteira ergométrica para a determinação de VO2max. Posteriormente, o [(0,177*V1600m + 8.101] VO2max real e previsto foi comparado com os genótipos da ECA. RESULTADOS: O VO2max e V1600m registrados para os genótipos DD, ID e II foram 45,6 (1,8; 51,9 (0,8 e 54,4 (1,0 mL.kg-1.min-1 e 211,2 (8,3; 249,1 (4,3 e 258,6 (5,4 m.min-1, respectivamente e foram significativamente mais baixos para os genótipos DD (p < 0,05. O VO2max real e previsto não diferiram entre si, apesar do genótipo da ECA, mas o nível de concordância entre os métodos de VO2max real e estimado foi menor para o genótipo DD. CONCLUSÃO: Concluiu-se que existe uma possível associação entre o genótipo da ECA, a aptidão cardiovascular e o desempenho em corridas de média distância de jovens do sexo masculino moderadamente ativos e que a precisão da previsão do VO2max também pode ser dependente do genótipo da ECA dos participantes.

    Spatial characterization of the variability of soil properties is a central point in site-specific agricultural management and precision agriculture. Geospatial measures of geophysical attributes are useful not only to rapidly characterize the spatial variability of soil properties but also for soil sampling optimization. This work reports partial results obtained at an experimental parcel under pasture located at Castro de Ribeira do Lea (Lugo/ Galicia/ Spain). An ECa automated survey was conducted in September 2011 employing an EM-38 DD (Geonics Ltd.) installed in a nonmetallic car, according to parallel lines spaced 10m one from each other and oriented at the east-west direction. The ECa values were recorded every second with a field computer and the locations were geo-referenced using a GPS. The entire survey was carried out in 1hour and 45 minutes and corrections due to differences in temperature were made. A total of 9.581 ECa registers were retained, configuring a sampling intensity of approximately 1 register per 1.5 m2. Employing the software ESAP 2.35 and the computational tool ESAP-RSSD, eighty positions were selected at the field to extract disturbed and undisturbed soil samples at two depths: 0.0-0.2m, 0.2-0.4m. Ten physical attributes (clay, silt, total sand, coarse sand and fine sand contents, soil bulk density, particle density, total porosity, soil water content, percentage of gravels) and 17 chemical attributes (soil organic matter-SOM, pH, P, K, Ca, Mg, Al, H+Al, Sum of bases-S, Cation exchange capacity-CEC, Base saturation-V%, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) were determined. The relationship between the geophysical variables and the soil attributes was performed using statistical and spatial analysis. There were significant correlations (p<0.01) between the geophysical variables and the textural attributes clay, silt, total sand and coarse sand contents. The biggest correlation (0.5623) was between ECa-V (vertical component) and clay content

    Full Text Available From its constitution onwards, the Volčji Potok Arboretum has been caught between various conflicting orientations. It is both a scientific, research and educational institution, and a cultural monument with exquisite garden and landscape design features and areas of great natural value and built cultural heritage, as well as commercial venue. At the same time, it functions as a park and an area for mass events, a garden centre and nursery. This variety of functions has helped Arboretum to survive the pressures of time; however, partial and uncoordinated interventions have threatened its original mission and its image and generated a number of conflicting situations. The workshop, organised on the initiative of the Institute for the Protection of Cultural Heritage of Slovenia, which involved students from the Faculty of Architecture and students from the Department of Landscape Architecture of the Biotechnical Faculty in mixed groups, generated eight proposals to solve some of the most urgent problems by introducing optimised development with clearly defined goals and priorities.

    Full Text Available Desde fines de 1998 la economía chilena se desaceleró mucho. Si entre 1988 y 1998 la tasa de crecimiento promedio alcanzó un 7.8%, durante el período postcrisis asiática fue de sólo un 3.7%. Sin embargo, junto con la desaceleración del crecimiento, la volatilidad de la economía se redujo prácticamente a la mitad.Este trabajo investiga, mediante un análisis empírico formal, el papel que tuvieron la introducción de la flotación cambiaria y la utilización de la regla de superávit estructural en transformar a Chile en una economía menos volátil. Nuestros resultados muestran que la introducción de la regla fiscal parece haber reducido en un tercio la volatilidad del crecimiento del PIB. Por su parte, la flotación cambiaria contribuyó a reducir esa volatilidad adicionalmente en alrededor de un cuarto. Así, en conjunto, ambas medidas aparecen como responsables de haber disminuido la volatilidad del crecimiento de la economía chilena en casi 60%. Estos resultados son robustos ante especificaciones y posibles problemas de endogeneidad en algunas de las variables explicativas.

    Interleukin-24 (IL-24) displays cancer-specific apoptosis-inducing properties in a broad spectrum of human tumors without harmful effects on normal cells. The human IL-24 protein is secreted as a glycosylated protein and functions as a pro-Th1 cytokine and a potent antiangiogenic molecule. However, the function of secreted recombinant human IL-24 (srhIL-24) protein in esophageal squamous cell carcinoma (ESCC) cells has not been studied. In the present study, we prepared a stable site-specific-integrated cell line, Flp-InTMCHO/IL-24 (FCHO/IL-24), which secreted rhIL-24 at a higher level than three random-integrated cell lines. In vitro, we identified that the purified srhIL-24 inhibited proliferation and induced the apoptosis of ESCC Eca-109 cells and activated STAT3, which was related with the IL-20 receptors. In vivo, the tumorigenicity of Eca-109 cells was significantly inhibited by s.c. injection of FCHO/IL-24 cells. Decreased tumor microvessel density and an increased number of TUNEL-positive tumor cells were associated with tumor growth inhibition, indicating the presence of antiangiogenic activity and induction of apoptotic activity. In summary, the present study demonstrated that srhIL-24 induced growth inhibition and apoptosis in ESCC Eca-109 cells in vitro and in vivo, which may be mediated by the receptor pathway.

  6. Microstructural effects on the spall properties of ECAE and SWAP magnesium alloys: AZ31B-4E and AMX602

    Science.gov (United States)

    Williams, C. L.; Farbaniec, L.; Kecskes, L.; Bradley, J.

    2017-01-01

    The effects of microstructure on the spall properties of two magnesium alloys fabricated via Equal-Channel Angular Extrusion (ECAE) and Spinning Water Atomization Process (SWAP) were investigated. The Hugoniot Elastic Limit (HEL) for both AZ31B-4E and AMX602 magnesium alloys were found to be approximately 0.181±0.003 GPa and 0.187±0.012 GPa, respectively. The spall strengths extracted from the free surface velocity profiles were found to decrease by approximately 4% for AZ31B-4E between 1.7 GPa to 4.6 GPa shock stress. Although this reduction in spall strength may lie within the experimental error, the microstructure of the post-shocked magnesium alloy show that manganese intermetallic inclusions in the AZ31B-4E magnesium were perhaps responsible for the reduction in spall strength as a function of shock stress. On the contrary, the spall strength for AMX602 was found to be random for the same shock stress range studied. This random behavior of the AMX602 was likely due to the incomplete sintering during mechanical processing. The fracture surfaces of both materials were dominated by nanovoids and the AMX602 fracture surface was found to be striated. A more in-depth study is needed to better understand the spall behavior of both materials.

    AIM: To study the role of P38 kinase in esophageal cancer cell apoptosis induced by genotoxin, cisplatin and the unfolded protein response (UPR) inducer, dithiothreitol(DTT).METHODS: Esophageal carcinoma cell line Eca109 was cultured in RPMI 1640 medium to 70% confluency and treated with either cisplatin, DTT, or cisplatin plus DTT in the presence or absence of P38 inhibitor, SB203580. The untreated cells served as the control. The esophageal carcinoma cell apoptosis was detected by agarose gel DNA ladder analysis and quantified by flow cytometry.The P38 phosphorylation was detected by immunohis-tochemistry using antibodies specific to phosphorylated P38 protein.RESULTS: (1) Both cisplatin and DTT induced apoptosis in the esophageal cancer cell line Eca109 as shown by DNA ladder formation; (2) As detected by antibodies specific for the phosphorylated P38 protein (p-P38), both cisplatin and DTT treatments activated the stress-activated enzyme, MAP kinase P38. The number of positive cells was about 50% for the treatment groups, comparing to that of 10% for untreated group. DTT treatment, but not cisplatin treatment, induces nuclear localization of p-P38;(3) As measured by flow cytometry, inhibition of P38 activity by SB203580 blocks DFT- and cisplatin-induced apoptosis.The rates for DTT, cisplatin, and DTT plus cisplatin-induced apoptosis were 16.8%, 17.1%, and 21.4%, respectively.Addition of the SB compound during the incubation reduced the apoptotic rate to about 7.6% for all the treatment groups, suggesting that P38 activation is essential for cisplatin- and DTT-induced apoptosis in Eca109 cells.CONCLUSION: (1) Both DTT and cisplatin were able to induce apoptosis in esophageal cancer cell line Eca109;(2) P38 MAP kinase is essential for DTT- and cisplatin-induced apoptosis in Eca109 cells; (3) P38 activation may be the common signaling component relaying the multiple upstream signaling events to the downstream cell death program.

    2017-03-01

    The reduction of ilmenite concentrate in 30vol% CO-70vol% N2 atmosphere was characterized by thermogravimetric and differential thermogravimetric (TG-DTG) analysis methods at temperatures from 1073 to 1223 K. The isothermal reduction results show that the reduction process comprised two stages; the corresponding apparent activation energy was obtained by the iso-conversional and model-fitting methods. For the first stage, the effect of temperature on the conversion degree was not obvious, the phase boundary chemical reaction was the controlling step, with an apparent activation energy of 15.55-40.71 kJ·mol-1. For the second stage, when the temperatures was greater than 1123 K, the reaction rate and the conversion degree increased sharply with increasing temperature, and random nucleation and subsequent growth were the controlling steps, with an apparent activation energy ranging from 182.33 to 195.95 kJ·mol-1. For the whole reduction process, the average activation energy and pre-exponential factor were 98.94-118.33 kJ·mol-1 and 1.820-1.816 min-1, respectively.

    2015-01-01

    Objective To investigate the effects of fentanyl on the invasion of esophageal squamous cell carcinoma cell line Eca109 and its possible mechanism. Methods Eca109 cells were treated with different concentrations of fentanyl(0. 5, 5, 50, 500 ng/ml), respectively, and the cells cultured with conventional medium were chosen as controls. Transwell assay was applied to test the cell in-vasion. RT-PCR and Western blot were used to detect the expression of matrix metalloproteinase 2 (MMP-2)and matrix metalloprotein-ase 9 (MMP-9) at mRNA and protein levels respectively. Results Transwell assay revealed that the fentanyl inhibited cell invasion at 48 h in a dose dependent manner(P<0. 05). RT-PCR and Western blot results showed that the fentanyl inhibited the mRNA and protein levels of MMP-2 and MMP-9 in a dose department manner(P<0. 05). Conclusion Fentanyl could inhibit the cell invasion of ESCC cell line Eca109 probably through down-regulating the expression of MMP-2 and MMP-9.%目的 探讨不同浓度芬太尼对食管鳞癌细胞株Eca109侵袭能力的影响及可能机制. 方法 选用不同浓度芬太尼(0. 5,5,50,500 ng/ml)干预食管鳞癌细胞株Eca109,以常规培养的Eca109作为对照,采用Transwell检测细胞侵袭能力,并应用RT-PCR和Western blot探讨芬太尼对 MMP-2 和 MMP-9 的 mRNA和蛋白表达的影响. 结果 各浓度组芬太尼孵育Eca109细胞48 h,与对照组相比,均能显著抑制细胞的侵袭(P<0. 05),且抑制率随着浓度升高而升高,呈浓度依赖性. 芬太尼孵育Eca109细胞48 h,与对照组相比,各浓度组均能抑制MMP-2和MMP-9的mRNA和蛋白的表达,同样呈浓度依赖性( P<0. 05). 结论 芬太尼可抑制食管鳞癌细胞株Eca109的侵袭,这种作用可能是基于对MMP-2和MMP-9表达的抑制.

    Integrative and conjugative elements (ICEs) contribute to the rapid evolution of bacterial pathogens via horizontal gene transfer of virulence determinants. ICEs have common mechanisms for transmission, yet the cues triggering this process under natural environmental or physiological conditions are largely unknown. In this study, mobilization of the putative ICE horizontally acquired island 2 (HAI2), present in the chromosome of the phytopathogen Pectobacterium atrosepticum SCRI1043, was examined during infection of the host plant potato. Under these conditions, mobilization of HAI2 increased markedly compared with in vitro cultures. In planta-induced mobilization of HAI2 was regulated by quorum sensing and involved the putative ICE-encoded relaxase ECA0613. Disruption of ECA0613 also reduced transcription of genes involved in production of coronafacic acid (Cfa), the major virulence factor harboured on HAI2, whereas their expression was unaffected in the quorum-sensing (expI) mutant. Thus, suppression of cfa gene expression was not regulated by the mobilization of the ICE per se, but was due directly to inactivation of the relaxase. The identification of genetic factors associated solely with in planta mobilization of an ICE demonstrates that this process is highly adapted to the natural environment of the bacterial host and can influence the expression of virulence determinants.

    Highlights: Black-Right-Pointing-Pointer We studied ECAE processing of Ti34Nb0.14O alloy and its thermomechanical behavior. Black-Right-Pointing-Pointer Ultra fine grain structure was developed by severe deformation and {alpha}-particles. Black-Right-Pointing-Pointer M{sub s} was largely decreased from 216 Degree-Sign C to 106 Degree-Sign C by severe grain refinement. Black-Right-Pointing-Pointer Subsequent {omega}-aging further stabilized {beta}-phase to show superelasticity. Black-Right-Pointing-Pointer Oxygen scavenging by {alpha}-particles greatly decreased martensite reorientation stress. - Abstract: The effect of ECAE (equal channel angular extrusion)-processing on the thermo-mechanical behavior of Ti34 wt.%Nb0.14 wt.%O shape memory alloy was studied by measuring the tensile stress-strain curve at various temperatures and using DSC, X-ray diffraction, and TEM. An ultrafine (0.4 {mu}m) grain structure was developed by severe plastic deformation and by the formation of alpha-particles on grain boundaries, which was facilitated by oxygen. Severe grain refinement led to a large decrease of M{sub s} from 216 Degree-Sign C to 106 Degree-Sign C. Furthermore, the elimination of oxygen by {alpha}-particles led to an abrupt decrease of the stress for reorienting the martensite variants and to an increase in the transformation strain. Subsequent {omega}-aging treatment further stabilized the {beta}-phase at room temperature, resulting in a superelastic property.

    为制备高性能铝锆耐热合金导体,首次采用 ECAE 动态时效成形工艺制备了 Al-Zr-B 合金导体.借助光学显微镜、材料拉伸试验机和双臂直流电桥等测试手段,研究了连续 ECAE动态时效成形 Al-Zr-B合金显微组织、力学性能和导电性能.结果表明:随着 ECAE 成形道次的增加,合金线材的组织逐渐趋于均匀;时效热处理可有效改善 Al-Zr-B合金导线的力学性能和导电性能.随着时效时间的延长,合金的抗拉强度先升高,出现峰值强度,再延长时效时间,强度降低;伸长率随着时间延长一直降低,等效导电率则不断升高.当时效温度180℃、时效时间12 h时,Al-0.3Zr-0.06B合金的拉伸强度为265.32 MPa、伸长率为6.7%、等效导电率为59.54%IACS,Al-Zr耐热合金导线的综合性能较好.%In order to prepare high performance aluminum zirconium heat-resistant conductor,Al-Zr-B alloy conductor was prepared by continuous dynamic aging ECAE (Equal Channel Angular Extrusion) process.By means of OM,electronic tensile machine and double arm direct current bridge,the microstructure, mechanical properties and electrical properties of Al-Zr-B alloy prepared by continuous dynamic aging ECAE process were studied.The result shows that the microstructure of the alloy wires become homogeneous gradually with the increase of the ECAE forming passes;the mechanical and electrical properties of Al-Zr-B alloy wire can be effectively improved by using artificial aging treatment.The tensile strength of the alloy increases with the aging time prolonged firstly, when rises to the peak strength,after that the strength decreases with the aging time further prolong;the elongation of the alloy decreases all the time;however,the equivalent conductivity increases. When the alloys soaked 180 ℃ for 12 h,the Al-Zr-B heat-resistant alloy wire has better complicated property,its tensile strength,elongation and the equivalent conductivity of the alloy is 265

    Tea polyphenols (-)-epigallocatechin-3-gallate (EGCG) and theaflavin-3-3'-digallate (TF3) are two prospective compounds in cancer prevention and treatment. Ascorbic acid (Vc) is essential to a healthy diet as well as being a highly effective antioxidant. In this work, the effects of the combination of EGCG or TF3 with Vc on the apoptosis and caspases-3/9 activities in human lung adenocarcinoma SPC-A-1 cells and esophageal carcinoma Eca-109 cells were determined. Furthermore, the role of mitogen-activated protein kinases (MAPK) pathways in the apoptosis induced by TF3 or EGCG together with Vc were studied using three MAPK inhibitors (ERK inhibitor PD98059, JNK inhibitor SP600125 and p38 inhibitor SB203580). Our results showed that Vc could enhance the EGCG and TF3 induced apoptosis in SPC-A-1 and Eca-109 cells, and this effect involved the activation of caspase-3 and 9. EGCG, TF3 and Vc could activate MAPK pathways respectively, and each compound activated different MAPK subfamilies in different cells. This may explain the enhancement of EGCG and TF3 induced apoptosis by Vc in SPC-A-1 and Eca-109 cells, and will ultimately aid the design of more effective anti-cancer treatments.

    Decitabine, a demethylating drug, is the first-line treatment for myelodysplastic syndromes and gains better overall survival, which is based on epigenetic mechanism. Activated by promoter demethylation, melanoma-associated antigens-A (MAGE-A), cancer-testis antigens are attractive targets for immunotherapy. Our purpose was to investigate whether decitabine could show anti-tumor effects for esophageal cancer and explore its mechanism. In addition, we aimed to examine its modulation for most MAGE-A members. The results showed the baseline expression were MAGE-A2, -3,-9, and -10 in Eca109 cells and decitabine (0.5 μM) could induce MAGE-A8 and -A4 whereas reduce MAGE-A9 and -A10. Moreover, decitabine (0.5 μM) inhibited cell proliferation, migration and invasive ability by 15%, 34% and 47.2%, respectively and decreased expressions of NF-κB2 and MMP2. Our results demonstrated that low-dose decitabine induced the expression of MAGE-A8 and -A4, and inhibited cell invasion through decreasing expression of MMP2 and NF-κB2, which provides possibilities for combing decitabine with immunotherapy targeting MAGE-A to treat advanced esophageal squamous cell carcinoma.

    To explore the molecular mechanisms of cellular stress response in the isorhamnetin-treated Eca-109 cells on the basis of the previous research in our lab. Data showed that the proliferation of Eca-109 cells was not absolutely arrested initially but still continued proliferation within the 72 h when these cells were exposed to isorhamnetin. It was found that the expression levels of NF-kB/p65 and NF-kB/ p50 were increased in nuclei at first. The expressions of COX-2, bcl-2 and mcl-1 were up-regulated with the treatment of isorhamnetin at first. IκBa and Bax were down-regulated initially but then up-regulated. After treated with MG-132 additionally, the nuclei expressions of p50/p65 were decreased and the proliferation of isorhamnetin-treated Eca-109 cells within the initial 72 h was inhibited. In conclusion, during the initial exposure to isorhamnetin, cellular stress response activated NF-kB signaling pathway, then changed the expression levels of the downstream gene expression to inhibit the apoptosis induced by isorhamnetin in the initial 72 h. But then the apoptosis induced by isorhamnetin plays a dominant role, which inhibits the NF-kB pathway and the proliferation of Eca-109 cells.%在前期研究的基础上,探究异鼠李素抑制食道癌细胞增殖作用过程中出现的细胞应激反应的分子机制.将食道癌Eca-109细胞经异鼠李素处理后,在前72h细胞出现持续增殖.前期细胞核内NF-κB/p65和NF-κB/p50的表达上升而后期逐渐降低;bcl-2、COX-2、mcl-1基因的表达在前期上调,后期下调;IκBa和bax的表达先下降而后上升;加入MG-132后NF-κB/p50和NF-κB/p65的核内表达明显降低,Eca-109细胞增殖受到抑制,在前72h细胞未出现持续快速增殖现象.表明在异鼠李素处理前期,通过食道癌细胞应激作用激活NF-κB信号途径,导致下游相关基因的表达变化从而抑制异鼠李素诱导Eca-109细胞的凋亡作用,而在处理后期异鼠李素诱导的细胞

    Full Text Available Antecedentes y Objetivos. La presencia de un septum en el primer compartimento extensor de la muñeca es una variante anatómica y una de las principales causas de persistencia o recurrencia del dolor después de cirugía en enfermedad de De Quervain. Es pues importante tenerlo en cuenta y conocer su incidencia en nuestra población, ya que en la literatura no hay uniformidad sobre su frecuencia de presentación. Material y método. Realizamos un estudio anatómico en 10 cadáveres mexicanos, en ambas manos, para identificar la estructura del primer compartimento extensor y documentar la presencia de septum entre nuestra población. Dado que en el Servicio de Cirugía Plástica y Reconstructiva del Hospital General de México es práctica habitual la búsqueda intencionada de dicho septum durante la cirugía del De Quervain, llevamos a cabo también una revisión de los expedientes de los pacientes atendidos por esta patología entre marzo del 2010 y marzo del 2013.

    A fine-grained stromatolite bed of great lateral continuity (km scale) and small synoptic relief (from 15 cm up to 40 cm) is registered in the Muñecas Formation (Floquet et al., 1982), of the Northern Iberian Ranges. Muñecas Fm is mainly composed of thin-bedded limestones and marls deposited during the late Turonian. At this time, the Iberian microplate was located in subtropical palaeolatitudes (20°N-30°N according Dercourt et al., 2000) and shallow-water carbonate platform facies were deposited in a wide and shallow seaway, along a NW-SE trending, intracratonic basin (Upper Cretaceous Iberian basin), between the emergent areas of the Hesperian massif to the W and the Ebro massif to the NE (Segura et al 2002). The stromatolite bed (facies 2.1) overlies heterolithic facies (facies 1.1) composed of marls and thin-bedded, massive mudstones with micritic intraclasts, ostracods and reworked sponges, and bearing quartz-silt and bioclastic-rich wavy bands. The coeval facies, laterally equivalent to the stromatolite bed, consist of an oolite-rich, sheet-like deposit (facies 2.2). Packstone and grainstone of radial-fibrous oolites overlie burrowed bioclastic mudstone-wackestones (facies 1.2) with bivalve fragments, gastropods, foraminifers, and sponges. The stromatolite bed is capped by ostracod-rich limestones (facies 3) and marls. The stromatolite posses a stratiform to LLH macrostructure, and in some places domed bioherms up to 1 m width occur. Internally, mesostructure is composed by planar, wavy to hemispherical stromatoids. They display a broad spectrum of microestructures: dense micrite, peloids (microbial as well as bahamite peloids), clotted microfabrics, irregular micritic-wall tubes and dendroid-arborescent microframeworks (filamentous cyanobacteria?). The microfacial study of the vertical arrangement of the stromatolite laminae reveals different growth stages probably related with environmental changes. In fact, the whole fine-grained stromatolite accretion

    Full Text Available Teniendo en cuenta el impacto que los resultados de los exámenes de calidad de la educación superior (ECAES tienen en la comunidad académica en general, se consideró importante estudiar aspectos sociodemográficos, psicol ógicos y condiciones educativas relacionadas con la vida universitaria, de estudiantes que obtuvieron puntajes en el examen ECAES, por encima de dos desviaciones estándar; calificación que supera al 97% de la poblaci ón que presenta este examen. Se pretende contribuir con este trabajo a la reflexión y análisis sobre el rendimiento académico, para incorporar los resultados encontrados, en el diseño de alternativas de trabajo que ayuden a otros estudiantes a alcanzar el éxito académico. En este estudio participaron 36 profesionales de psicología, egresados de cinco universidades colombianas. Se encontró que estos estudiantes se caracterizan porque atribuyen su alto puntaje en el ECAES a su capacidad intelectual, consideran que el éxito académico se debe a su esfuerzo personal, no tienen problemas para leer y comprender textos en inglés, tienen fácil acceso a Internet, se encuentran motivados para seguir estudiando luego de culminar su carrera universitaria, desean realizar estudios fuera del país, las actividades académicas desarrolladas en la universidad tenían sentido para ellos, no les preocupaba que los docentes fueran estrictos, se encontraban orgullosos de pertenecer a su universidad y consideraban que su opinión era tenida en cuenta al momento de tomar decisiones en su familia. Los resultados suministrados por la prueba AF-5, muestran que tienen un autoconcepto alto en la dimensión académico-laboral.

    2006-09-01

    Full Text Available Inhibition of Angiotensin Converting Enzyme (ACE is a modern therapeutic target in the treatment of hypertension. Within the enzyme cascade of the renin-angiotensin system, ACE removes histidyl-leucine from angiotensin I to form the physiologically active octapeptide angiotensin II, one of the most potent known vasoconstrictors. Therefore, a rationale for treating hypertension would be to administer drugs or natural compounds which selectively inhibit ACE. The present work constitutes a review of the literature of plants and chemically defined molecules from natural sources with in vitro anti-hypertensive potential based on the inhibition of ACE. The review refers to 321 plants, the parts utilized, type of extract and whether they are active or not. It includes also the names of 158 compounds isolated from higher plants, marine sponges and algae, fungi and snake venom. Some aspects of recent research with natural products directed to produce anti-hypertensive drugs are discussed. In this review, 148 references were cited.A inibição da Enzima Conversora da Angiotensina (ECA é um alvo terapêutico moderno e eficaz no tratamento da hipertensão arterial. Na cascata enzimática que envolve o sistema renina-angiotensina, a ECA promove a remoção dos aminoácidos histidil-leucina da angiotensina I para formar o octapeptídio angiotensina II, a qual é fisiologicamente ativa em diversos sistemas, e considerado como um dos mais potentes vasoconstrictores endógenos conhecido. Portanto, uma racionalidade no tratamento da hipertensão seria administrar drogas ou compostos de origem natural que inibam seletivamente a ECA. O presente estudo constitui uma revisão da literatura sobre plantas e moléculas de origem natural com potencial anti-hipertensivo, baseado na inibição in vitro da ECA. A revisão referencia 321 plantas, partes usadas, tipo de extrato e se é ativo ou não. Inclui ainda o nome de 158 compostos isolados de plantas superiores

    Full Text Available Welcome to the first appearance of PORTAL for 2006 (vol. 3, no. 1, a special issue entitled ‘Other Worlds’ guest edited by James Goodman and Christina Ho from the Faculty of Humanities and Social Sciences, University of Technology Sydney (UTS. The papers collected in this special issue focus on what the guest editors call “the transformative power of social movements” that respond to the processes and discourses of globalization and globalism by generating alternative sites and spaces of agency, or ‘other worlds.’ The contributors to the issue originally presented papers at a conference held in April 2005 in Sydney, with the title ‘Other Worlds: Social Movements and the Making of Alternatives.’ That conference was organized by the Research Initiative on International Activism at UTS, and supported by the Research Committee on Social Movements and Collective Action of the International Sociological Association. The Editorial Committee of PORTAL would like to thank both institutions for their support of the event that led to this special issue. I would also like to thank Wayne Peake, Kate Barclay, and Murray Pratt for their editorial efforts in seeing this issue through to publication. The Editorial Committee is pleased to showcase in the Cultural Works Section a short meditative piece by local writer Joel Scott, who is currently undertaking studies in Pamplona, Spain. When considered in the context of the special issue’s discussions of ‘other worlds’ that precede it, Scott’s ‘God, We’re Not Immigrants! A Reflection on Moving and Staying,’ provides an evocative insight into the sociocultural and imaginative limits that may preclude the construction of alternative ‘worlds.’

    Pérez, I.

    2011-02-01

    Full Text Available In the present work, a study on the modification of the mechanical properties of the aluminium alloy AA6060 F has been made when severe plastic deformation is applied to it through Equal Channel Angular Extrusion (ECAE. Moreover, a study about the effect of the artificial aging on the modification of such mechanical properties has been carried out after having processed the material by ECAE. In order to do this, thermal treatments at different values of temperature and holding time have been performed. Hardness, tensile tests and Charpy impact test, along with metallographic techniques, have been carried out in order to analyse the mechanical behaviour and the state of the material. In spite of the existence of several studies that have analysed the effect of aging thermal treatments on 6000 aluminium alloys, such studies are focused on laboratory alloys with industrial compositions not very usual. Therefore, in the present work, the employed starting material is a commercial alloy as-cast, which has not been studied up to now.

    En el presente trabajo se ha realizado un estudio de la modificación de las propiedades mecánicas de la aleación de aluminio AA6060 F, al ser deformada mediante deformación plástica severa empleando el proceso de extrusión en canal angular (ECAE. Asimismo, se ha efectuado un estudio del efecto del envejecimiento artificial sobre la modificación de dichas propiedades mecánicas. Para ello, se han realizado tratamientos térmicos a diferentes temperaturas y tiempos de permanencia, efectuando mediciones de dureza, ensayos de tracción, ensayos con péndulo Charpy y técnicas de revelado metalográfico, para conocer los comportamientos mecánicos y el estado del material. Existe un elevado número de publicaciones, que han analizado el efecto de tratamientos térmicos de envejecimiento en aleaciones de la serie 6000. Sin embargo, la aleación AA6060 no ha sido tan ampliamente estudiada. Por ello, en este trabajo

Alguns destes dependem da fisiologia da abelha, dos procedimentos após a colheita e no mel de melato há também a interferência de insetos sugadores e das formigas. Várias substâncias voláteis já foram identificadas, sendo algumas características de determinados méis uniflorais. Com o objetivo de encontrar uma substância volátil característica do mel de melato, seis amostras deste tipo de mel e seis amostras de mel floral foram analisadas usando extração por arraste de gás hidrogênio e cromatografia a gás acoplada a espectrometria de massas. Ácido acético foi encontrado em quatro amostras de mel de melato e em uma amostra de mel floral porém, com menor abundância.

    Full Text Available Abstract The structures of the canine, rabbit, bovine and equine EIF2AK2 genes were determined. Each of these genes has a 5' non-coding exon as well as 15 coding exons. All of the canine, bovine and equine EIF2AK2 introns have consensus donor and acceptor splice sites. In the equine EIF2AK2 gene, a unique single nucleotide polymorphism that encoded a Tyr329Cys substitution was detected. Regulatory elements predicted in the promoter region were conserved in ungulates, primates, rodents, Afrotheria (elephant and Insectifora (shrew. Western clawed frog and fugu EIF2AK2 gene sequences were detected in the USCS Genome Browser and compared to those of other vertebrate EIF2AK2 genes. A comparison of EIF2AK2 protein domains in vertebrates indicates that the kinase catalytic domains were evolutionarily more conserved than the nucleic acid-binding motifs. Nucleotide substitution rates were uniform among the vertebrate sequences with the exception of the zebrafish and goldfish EIF2AK2 genes, which showed substitution rates about 20% higher than those of other vertebrates. FISH was used to physically assign the horse and cattle genes to chromosome locations, ECA15q24–q25 and BTA11q12–15, respectively. Comparative mapping data confirmed conservation of synteny between ungulates, humans and rodents.

    Max, C.E.

    1981-12-01

    This monograph deals with the physics of the coronal region in laser fusion targets. The corona consists of hot plasma which has been evaporated from the initially solid target during laser heating. It is in the corona that the laser light is absorbed by the target, and the resulting thermal energy is conducted toward cold high-density regions, where ablation occurs. The topics to be discussed are theoretical mechanisms for laser light absorption and reflection, hot-electron production, and the physics of heat conduction in laser-produced plasmas. An accompanying monograph by H. Ahlstrom (Vol.II) reviews the facilities, diagnostics, and data from recent laser fusion experiments.

  9. Reposição volêmica em pacientes politraumatizados

    Full Text Available O debate sobre a administração de colóides, cristalóides, soluções hipertônicas ou elementos sanguíneos em pacientes críticos estende-se desde o século 19. Algumas dessas soluções podem ser diferentemente distribuídas nos espaços intra e extravasculares, assim como nos espaços intra e extracelulares, causando diferentes efeitos fisiológicos. Diversos estudos foram realizados com o objetivo de comparar um fluido ao outro, mostrando a eficácia e as vantagens de cada um. Porém, não existe um trabalho que consiga provar uma diferença significativa em relação à morbi-mortalidade após a reposição volêmica com cada tipo de fluido. Esses estudo, por serem diferentes em relação aos protocolos de ressucitação, volumes e tipos de fluidos utilizados, dificultam a comparação dos resultados; no entanto, sabe-se que a reposição volêmica depende de cada situação clínica. A utilização da reposição volêmica pré-hospitalar é discutível, visto que pode aumentar o sangramento ou mesmo ser motivo de atraso na transferência do paciente ao hospital, ao mesmo tempo em que pode reduzir o risco de isquemia tecidual. Uma vez que a hemorragia tenha sido controlada, há um consenso para o fato de que o volume intravascular deve ser reposto da forma mais rápida e eficaz possível para minimizar a quantidade de células afetadas diretamente pela má perfusão tecidual. Os atuais trabalhos envolvidos nessa polêmica trazem resultados que sugerem a continuidade das investigações, visto que nenhum deles atingiu um ponto final comum. Desses estudos, um aspecto com o qual todos concordam e que se tornou claro é que não existe uma fórmula mágica única de administração intravenosa para os pacientes politraumatizados. Este trabalho visa, por meio de revisão bibliográfica, mostrar os tipos de fluidos a serem utilizados para reposição volêmica de pacientes politraumatizados, assim como os meios e a forma de utilização dos

Historical part and theoretical part construct the general writing logic togeth-er, historical part sets up theoretical direction for research afterwards. The implications are of the following: (1) Based on ' organic growth' of historical productive mode, the core of the category is surplus value ; (2) From the movement of category production to disclose historical structural growth ; ( 3 ) Through the general ' production' of theories, it shows the internal integration between critique on methodology and critique on epistemology. Thus Vol. 4 of ' Das Kapital' rejected the wrong demand in ' History of the Theory of Surplus Value' edited by Kautsky.

    Antiviral quinolones are promising compounds in the search for new therapeutically effective agents for the treatment of AIDS. To rationalize the SAR for this new interesting class of anti-HIV derivatives, we performed a 3D-QSAR study on a library of 101 6-fluoro and 6-desfluoroquinolones, taken either from the literature or synthesized by us. The chemometric procedure involved a fully semiempirical minimization of the molecular structures by the AMSOL program, which takes into account the solvatation effect, and their 3D characterization by the VolSurf/GRID program. The QSAR analysis, based on PCA and PLS methods, shows the key structural features responsible for the antiviral activity.

The approach is to construct a sequence of explicit complete metrics on them such that the sectional curvatures are bounded in absolute value by 1 and the volumes tend to zero. As a direct consequence, we get that MinVol (Rn = 0 for n > 3.Neste artigo fornecemos uma demonstração elementar do resultado de que os volumes minimais de R³ e R4 são ambos iguais a zero.

    Full Text Available En este trabajo se aplican y se extienden los patrones de evolución de filiales planteados por Birkinshaw y Hood, al estudiar la influencia de los entornos volátiles sobre los procesos de evolución de las filiales de empresas multinacionales. Utilizando una metodología cualitativa a través de 41 estudios de casos de filiales de diversos sectores localizadas en Venezuela, se observó que las mismas siguen procesos conducentes a la mejora, el refuerzo y al declive de sus roles. En los resultados se identifican a la matriz y la propia filial como impulsores de esos procesos, pero se aprecia también al entorno local como determinante de la evolución de las filiales, con lo cual se extienden los patrones que plantean Birkinshaw y Hood que consideran sólo a la matriz y a la propia filial. Como conclusión, no sólo se resalta la importancia del entorno en la determinación del rol de las filiales, sino que se evidencia que los entornos volátiles pueden tener un impacto tanto positivo como negativo en la evolución de la filial.

    Full Text Available Venous thromboembolism is a common multifactorial disease associated with acquired and inherited predisposing factors. Several polymorphisms, e.g. factor V Leiden, factor II G20210A and deficiency of antithrombin, protein C and protein S, have been associated with venous thromboembolism. Angiotensin converting-enzyme affects hemostasis by decreasing fibrinolysis. Angiotensin converting-enzyme gene polymorphism, a 287 pb insertion/deletion at introns 16, is related to variations in enzyme serum levels. The DD genotype has been associated with increased risk for venous thrombosis. This study examined the frequency of the angiotensin converting-enzyme alleles I and D and their association with venous thrombosis in a group of individuals from the south of Brazil. Seventy-one patients with deep venous thrombosis and/or pulmonary thromboembolism and 71 healthy individuals were analysed in a case-control study. The angiotensin converting-enzyme ID genotyping was performed by polymerase chain reaction. The frequencies of the D allele and DD genotype were, respectively, 51.4% and 22.5% for patients, and 64.7% and 45.0% for controls. The Odds Ratio for the dominant hypothesis (DD+ID versus II genotypes was 0. 75 (CI 95%; 0.29-1.93 and the Odds Ratio for recessive hypothesis (DD versus ID+II was 0.35 (CI 95%; 0.16-0.78. In conclusion, our results indicate a protective effect of the angiotensin converting-enzyme DD genotype on venous thromboembolism.O troemboembolismo venoso (TEV é uma doença multifatorial associada com fatores de risco adquiridos e hereditários.

    Full Text Available Antjie Krog’s translation of Henk van Woerden’s novel Een mond vol glas (A mouth full of glass Against a historical backdrop several critical approaches to translational theory are explicated. Traditional criticism seems to imply positioning between the Source Text (ST and the Target Text (TT. A functionalist approach (as propagated among others by Snell-Hornby, Nord and Naaijkens is a descriptive rather than a normative approach that focuses almost exclusively on the ST. This approach is consequently adopted in the evaluation of Krog’s translation; yet even within this more relativistic paradigm, a comparison between ST and TT should not be evaded. In the case of Krog’s translation, this comparison leads to the identification of scores of lexical, grammatical and stylistic errors.

    Full Text Available The present study deals with the mechanical characterization at temperatures between 25 and 300 °C of a magnesium matrix composite reinforced with a 10 % volume fraction of titanium particles. The Mg-10Ti (vol.% composite was processed by a powder metallurgy involving mixing of powders, cold pressing and extrusion at 400 °C. The composite shows high strength (218 MPa and some elongation (4,7 % at room temperature, higher than those reported for most of magnesium matrix composites. The gradual decrease in the mechanical properties of the composite at temperatures above 100 °C indicates the beneficial effect of titanium reinforcement.

    To compare hepatic parenchymal contrast media (CM) enhancement during multi-detector row computed tomography (MDCT) and its correlation with volume pitch-corrected computed tomography dose index (CTDI{sub vol}) and body weight (BW). One hundred patients referred for standard three-phase thoraco-abdominal MDCT examination were enrolled. BW was measured in the CT suite. Forty grams of iodine was administered intravenously (iodixanol 320 mg I/ml at 5 ml/s or iomeprol 400 mg I/ml at 4 ml/s) followed by a 50-ml saline flush. CTDI{sub vol} presented by the CT equipment during the parenchymal examination was recorded. The CM enhancement of the liver was defined as the attenuation HU of the liver parenchyma during the hepatic parenchymal phase minus the attenuation in the native phase. Liver parenchymal enhancement was negatively correlated to both CTDI{sub vol} (r = -0.60) and BW (r = -0.64), but the difference in correlation between those two was not significant. CTDI{sub vol} may replace BW when adjusting CM doses to body size. This makes it potentially feasible to automatically individualize CM dosage by CT. (orig.)

  11. 'tomo_display' and 'vol_tools': IDL VM Packages for Tomography Data Reconstruction, Processing, and Visualization

    Rivers, M. L.; Gualda, G. A.

    2009-05-01

    One of the challenges in tomography is the availability of suitable software for image processing and analysis in 3D. We present here 'tomo_display' and 'vol_tools', two packages created in IDL that enable reconstruction, processing, and visualization of tomographic data. They complement in many ways the capabilities offered by Blob3D (Ketcham 2005 - Geosphere, 1: 32-41, DOI: 10.1130/GES00001.1) and, in combination, allow users without programming knowledge to perform all steps necessary to obtain qualitative and quantitative information using tomographic data. The package 'tomo_display' was created and is maintained by Mark Rivers. It allows the user to: (1) preprocess and reconstruct parallel beam tomographic data, including removal of anomalous pixels, ring artifact reduction, and automated determination of the rotation center, (2) visualization of both raw and reconstructed data, either as individual frames, or as a series of sequential frames. The package 'vol_tools' consists of a series of small programs created and maintained by Guilherme Gualda to perform specific tasks not included in other packages. Existing modules include simple tools for cropping volumes, generating histograms of intensity, sample volume measurement (useful for porous samples like pumice), and computation of volume differences (for differential absorption tomography). The module 'vol_animate' can be used to generate 3D animations using rendered isosurfaces around objects. Both packages use the same NetCDF format '.volume' files created using code written by Mark Rivers. Currently, only 16-bit integer volumes are created and read by the packages, but floating point and 8-bit data can easily be stored in the NetCDF format as well. A simple GUI to convert sequences of tiffs into '.volume' files is available within 'vol_tools'. Both 'tomo_display' and 'vol_tools' include options to (1) generate onscreen output that allows for dynamic visualization in 3D, (2) save sequences of tiffs to disk

    The prediction of human intestinal absorption is a major goal in the design,optimization,and selection of candidates for the develoment of oral drugs.In this study,a computerized method(VolSurf with GRID) was used as a novel tool for predicting human intestinal absorption of test compound,and for determining the critical molecular properties needed for human intestinal absorption.The tested molecules consisted of 20 diverse drug-like compounds.Partial least squares(PLS) discriminant analysis was used to correlate the experimental data with the theoretical molecular properties of human intestinal absorption.A good correlation(r2=0.95,q2=0.86) between the molecular modeling results and the experimental data demonstrated that human intestinal absorption could be predicted from the three-dimensional(3D) molecular structure of a compound .Favorable structureal properties identified for the potent intestinal absorption of drugs included strong imbalance between the center of mass of a molecule and the barycentre of its hydrophilic and hydrophobic regions and a definitive hydrophobic region as well as less hydrogen bonding donors and acceptors in the molecule.

    Full Text Available Within alumina particle suspension yttria precursor was precipitated with ammonium carbonate. Drying and calcination at 600°C resulted in the mixture of alumina and yttria particles, the latter being much finer than alumina particles. This mixture was additionally homogenized by short attrition milling in aqueous suspension of pH selected on the basis of zeta (ζ potential measurements. It was found that acidic conditions (realized with HNO3 resulted in hard agglomerates. Such powder shows poor sintering ability. Much better properties showed powders homogenized under basic conditions. They give dense materials composed of YAG inclusions within alumina matrix. YAG particles resulted from the reaction of Y2O3 with Al2O3 during heat treatment. Homogenization of the system mixed at pH=8, corresponding to the heterofloculation conditions, is slightly better than observed at pH=10. YAG inclusions (20 vol% increase hardness and fracture toughness of the material in comparison with pure alumina polycrystals.

  1. Solidification of Magnesium (AM50A) / vol%. SiCp composite

    Zhang, X.; Hu, H.

    2012-01-01

    Magnesium matrix composite is one of the advanced lightweight materials with high potential to be used in automotive and aircraft industries due to its low density and high specific mechanical properties. The magnesium composites can be fabricated by adding the reinforcements of fibers or/and particles. In the previous literature, extensive studies have been performed on the development of matrix grain structure of aluminum-based metal matrix composites. However, there is limited information available on the development of grain structure during the solidification of particulate-reinforced magnesium. In this work, a 5 vol.% SiCp particulate-reinforced magnesium (AM50A) matrix composite (AM50A/SiCp) was prepared by stir casting. The solidification behavior of the cast AM50A/SiCp composite was investigated by computer-based thermal analysis. Optical and scanning electron microscopies (SEM) were employed to examine the occurrence of nucleation and grain refinement involved. The results indicate that the addition of SiCp particulates leads to a finer grain structure in the composite compared with the matrix alloy. The refinement of grain structure should be attributed to both the heterogeneous nucleation and the restricted primary crystal growth.

    Aluminium (Al) alloys are widely used in various industries, such as automotive and aerospace. The production processes in these sectors create large amount of Al residues. In this paper, a new method of recycling Al chip is presented. Metal matrix composite (MMCs) of Al-20 vol% Sn was prepared by using solid state direct conversion method of recycled Al 6061 alloy. Constant pressure (10 ton) was used to implement the cold forging process. The differences of sintering temperature (200 °C, 250 °C, 300 °C and 350 °C) and time intervals (1h, 2h, 3h, 4h and 5h) were studied to obtain the optimum hardness, strength and surface integrity of Al-20 vol% Sn. The results showed that, hardness and strength of Al-20 vol% Sn was decreased by additional temperature and increase with time interval of sintering. Sintering temperature at 350 °C produces better morphology structure of Al-Sn composites.

    The Computed Tomography (CT) is an important diagnostic imaging method, widely used. However, in spite of all the advantages and technologic advances within the CT scanners, the tomographic procedures result in high absorbed doses to patients. The main objective of this work was to perform a dosimetric study of CT scanners located at Recife and to evaluate the image quality on CT examinations in these equipment. The volume CT air kerma index (C{sub VOL}) and air kerma length product (P{sub KL,CT}) were estimated. These values were calculated using normalized weighted air kerma indexes in CT standard dosimetry phantoms ({sub n}C{sub W}), supplied by ImPACT group for several CT scanners, and the scan parameters of routine head, routine chest and hi-resolution chest CT exams performed at 20 institutions. The irradiation parameters of 15 adult patients for each CT procedure were registered at six participating centres, at which the phantom from the American College of Radiology (ACR) CT accreditation protocol was used for the image quality measurements. For routine head exams, the C{sub VOL} values varied between 12 and 58 mGy (at the posterior fossa) and 15 to 58 mGy (at the cerebrum) and the P{sub KL,CT}, from 150 to 750 mGy{center_dot}cm. The C{sub VOL} values for routine chest procedures varied from 3 to 26 mGy and the P{sub KL,CT}, between 120 and 460 mGy{center_dot}cm. In relation to Hi-resolution chest exams, C{sub VOL} values were from 1.0 to 2.7 mGy and the P{sub KL,CT} values varied between 24 and 67 mGy{center_dot}cm. The image quality evaluations results showed that almost all scanners presented at least one inadequacy. One of the equipment presented faults at 70% of the tests. With regard to the image noise, only two scanners presented acceptable results. From these results, it is possible to conclude that the volume CT air kerma index values are lower than the European reference levels. However, the image quality of these CT scanners does not attend the

    UDP-glucuronosyltransferase 2B7 (UGT2B7) is an important enzyme responsible for clearance of many drugs. Here, we report two 3D quantitative structure-activity relationship (QSAR) models for UGT2B7 using the pharmacophore and VolSurf approach, respectively. The dataset included 53 structurally diverse UGT2B7 substrates, 36 of which were used for the training set and 17 of which for the external test set. Pharmacophore-based 3D-QSAR model (or hypothesis) was developed using the Discovery Studio program. A user-defined "glucuronidation site" feature was forcefully included in a pharmacophore hypothesis. VolSurf-based 3D-QSAR model was generated using the VolSurf program. This involves calculation of VolSurf descriptors, variable selection with the FFD algorithm, and partial least squares (PLS) analyses. The best pharmacophore model (r(2) = 0.736) consists of one glucuronidation site, one hydrogen bond acceptor, and three hydrophobic regions. Using this model, K(m) values for 14 of 17 test substrates were predicted within one log unit. The yielded VolSurf (PLS) model with two components shows statistical significance in both fitting and internal predicting (r(2) = 0.866, q(2) = 0.728). Further, the K(m) values for all test substrates were predicted within one log unit. In addition, the VolSurf model reveals an overlay of chemical features influencing the enzyme-substrate binding. Those include molecular size and shape, integy moments, capacity factors, best volumes of DRY probe, H-bonding, and log P. In conclusion, the pharmacophore and VolSurf approaches are successfully utilized to establish predictive models for UGT2B7. The derived models should be an efficient tool for high throughput prediction of UGT2B7 metabolism.

    2015-04-15

    This handbook was prepared primarily with the aim to provide information to experts in industry, authorities or research facilities engaged in criticality-safety-related problems that will allow an adequate and rapid assessment of criticality safety issues already in the planning and preparation of nuclear facilities. However, it is not the intention of the authors of the handbook to offer ready solutions to complex problems of nuclear safety. Such questions have to remain subject to an in-depth analysis and assessment to be carried out by dedicated criticality safety experts. Compared with the previous edition dated December 1998, this handbook has been further revised and supplemented. The proven basic structure of the handbook remains unchanged. The handbook follows in some ways similar criticality handbooks or instructions published in the USA, UK, France, Japan and the former Soviet Union. The expedient use of the information given in this handbook requires a fundamental understanding of criticality and the terminology of nuclear safety. In Vol. 1, ''Criticality and Nuclear Safety'', therefore, first the most important terms and fundamentals are introduced and explained. Subsequently, experimental techniques and calculation methods for evaluating criticality problems are presented. The following chapters of Vol. 1 deal i. a. with the effect of neutron reflectors and absorbers, neutron interaction, measuring methods for criticality, and organisational safety measures and provide an overview of criticality-relevant operational experience and of criticality accidents and their potential hazardous impact. Vol. 2 parts 1 and 2 finally compile criticality parameters in graphical and tabular form. The individual graph sheets are provided with an initially explained set of identifiers, to allow the quick finding of the information of current interest. Part 1 includes criticality parameters for systems with {sup 235}U as fissile material, while part

    This article focuses on correcting several factual errors and critiques in the previously published Letter in Phys. Rev. L, Vol. 89, No. 10, 2022, by D. Shapira and M. Saltmarsh. The authors of the Letter did not perform their own "independent" experiments as claimed; they did not perform control experiments with normal acetone; and, neither did they monitor for tritium. It their Letter, the authors (D. Shapira and M.

Este estudo teve como objetivo verificar o efeito do processamento na composição de voláteis do suco clarificado de maçãs Fuji. O isolamento dos voláteis foi feito por enriquecimento do "headspace" em polímero poroso e eluição com hexano. Oitenta e quatro compostos voláteis foram detectados na maçã Fuji, por cromatografia gasosa de alta resolução, dos quais 30 foram identificados por espectrometria de massas, aliada aos índices de Kovats. A classe química predominante na maçã Fuji, dentre os compostos identificados, foi a dos ésteres, compreendendo ao todo 28 voláteis. Os compostos majoritários na fruta foram a-farneseno, acetato de 2-metil butila, acetato de butila e acetato de hexila. Após a prensagem, o aldeído hexanal aumentou drasticamente e se tornou majoritário. A clarificação foi a etapa que menos causou modificações na composição de voláteis, mantendo o aldeído como majoritário. A pasteurização foi a etapa crítica do processamento, como esperado. Nesta etapa, além de ocorrer a diminuição da área de todos os componentes voláteis, ocorreu a perda total do éster octanoato de isoamila e de 15 compostos não identificados. No entanto, os compostos voláteis majoritários após a prensagem e em todas as etapas do processamento foram os mesmos: acetato de butila, acetato de 2-metil butila, acetato de hexila e um composto não identificado.

    We developed simplified analysing method of C-11 PIB PET using a ligand and subject specific PET templates and evaluated the usefulness of this method by comparing standard MR-based methods in Alzheimer disease (AD). We studied 7 patients with AD (71.5{+-}11.5, M/F=3/4) and 5 normal controls (68.4{+-}8.9, M/F=1/4) with C-11 PIB PET and T1 MRI. 90-min dynamic PET scan was performed after injection of C-11 PIB (370 MBq). Region to cerebellar ratio image (ratio image) was obtained from 60-90 min image and distribution volume ratio image (DVR image) was obtained from 90-min dynamic image using a Logan graphical analysis. Ligand and subject specific PET templates were created by spatial normalization of MR coregistered ratio images of AD and normal group to T1 MR MNI template using SPM2. We compared the outcome of voxel based and automatic VOl analysis employing 3 parametric images: MR template based spatially normalized MR coregistered DVR image (MR-DVR image), MR template based normalized MR coregistered ratio image (MR-ratio image), AD and normal group specific PET template based normalized ratio image (PET-ratio image) in all subjects. Voxel based analyses using 3 parametric images revealed significantly increased PIB retention in several brain regions such as both orbitofrontal and temporoparietal cortices and posterior cingulated gyri of AD compared to normal (FDR<0.05), however, the z-values of these regions were more higher in PET- and MR-ratio images than in MR-DVR image. Automatic VOl analyses using 3 parametric images also revealed significantly increased PIB retention values in same regions of AD (p<0.05). PIB retention values in PET-ratio images were significantly correlated with those in MR-ratio images (R=0.96, slope=0.99, p<0.001) and also MR-DVR images (R=0.95, slope = 1.8, p<0.001). Voxel based and automatic VOl analysis can be simply and accurately performed in a single static C-11 PIB PET image using a ligand and subject specific PET templates

    Full Text Available There has been a growing interest in the food industry and in preventive medicine to search for «natural antioxidants». Therefore the objetive of this study was to evaluate the antioxidant activity of the non-volatile residue of essential orange oil in the oxidation of unrefined and freshly extracted olive oil. Essential orange oil was distilled to obtain a non-volatile residue and fracctionated on a Silica Gel 60 column. The antioxidant activity was determined by measuring peroxide value obtained after heating olive oil at 70 °C for 48 h. Six compounds were isolated and purified, four of these had antioxidant activity, α-tocopherol and three methoxylated flavones were identified using spectroscopic methods. This study confirmed that non-volatile fractions of essential orange oil contain natural antioxidants diferent from α-tocopherol.

    Existe un creciente interés en la industria alimentaria y en la medicina preventiva por la búsqueda de «antioxidantes naturales», por lo que nos planteamos evaluar la actividad antioxidante del residuo no volátil del aceite esencial de naranja contra la oxidación del aceite de oliva sin retinar y de reciente extracción. Mediante destilación del aceite esencial de naranja se obtuvo el residuo no-volátil, el cual se fraccionó en columna de silica gel 60. La actividad antioxidante fue medida por el valor de peróxidos producidos por el aceite de oliva al provocar la oxidación por calentamiento a 70 °C durante 48 h. Se aislaron seis compuestos mediante HPLC preparativo de los cuales cuatro tuvieron actividad antioxidante. Usando métodos espectroscópicos se identificaron α-tocoferol y tres flavonas metoxiladas. Con este estudio se confirmó que la fracción no volátil del aceite esencial de naranja contiene antioxidantes naturales diferentes al α-tocoferol.

    Diffusion brazing of Al-6061 alloy containing 15 vol. pct Al2O3 particles was attempted using Cu-Sn interlayer. Joint formation was attributed to the solid-state interdiffusion of Cu and Sn followed by eutectic formation and subsequent isothermal solidification. Examination of the joint region using scanning electron microprobe analyzer (EPMA), wavelength dispersive spectroscopy (WDS) and X-ray diffraction (XRD) showed the formation of intermetallic phases such as Al7Cu3Mg3, Mg2Cu6Al5, Cu3Sn, and Mg2Sn. The results indicated an increase in joint strength with increasing bonding time giving the highest joint shear strength of 94 MPa at a bonding duration of 3 hours.

    The enhancement of the stratospheric aerosol layer by volcanic eruptions induces a complex set of responses causing global and regional climate effects on a broad range of timescales. Uncertainties exist regarding the climatic response to strong volcanic forcing identified in coupled climate simulations that contributed to the fifth phase of the Coupled Model Intercomparison Project (CMIP5). In order to better understand the sources of these model diversities, the Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) has defined a coordinated set of idealized volcanic perturbation experiments to be carried out in alignment with the CMIP6 protocol. VolMIP provides a common stratospheric aerosol data set for each experiment to minimize differences in the applied volcanic forcing. It defines a set of initial conditions to assess how internal climate variability contributes to determining the response. VolMIP will assess to what extent volcanically forced responses of the coupled ocean-atmosphere system are robustly simulated by state-of-the-art coupled climate models and identify the causes that limit robust simulated behavior, especially differences in the treatment of physical processes. This paper illustrates the design of the idealized volcanic perturbation experiments in the VolMIP protocol and describes the common aerosol forcing input data sets to be used.

    Full Text Available El presente es un trabajo experimental piloto, abierto, para conocer el efecto, dosis efectiva y efectos secundarios del aceite de sacha inchi (Plukenetia volúbilis L en el perfil lipídico de pacientes con hipercolesterolemia; para ello, se incluyó a 24 pacientes de 35 a 75 años, en quienes se determinó los valores sanguíneos de colesterol total (CT, HDL, triglicéridos (Tg, glucosa, ácidos grasos no esterificados (AGNE e insulina Se aleatorizó a los participantes para recibir 5 mL o 10 mL de una suspensión conteniendo 2gr/5ml de aceite de sacha inchi, durante cuatro meses. La ingesta del aceite produjo caída en los valores promedio del CT, y AGNE con elevación del c-HDL en ambos grupos. La dosis de 10 mL se asoció a mayores niveles de insulina en el grupo aleatorizado a recibir 10 ml. El aceite de sacha inchi parece tener efectos benéficos sobre el perfil lipídico en pacientes con dislipidemia, requiriéndose la evaluación de su eficacia y seguridad en ensayos clínicos aleatorizados.We performed a pilot, experimental, open study in order to know the effect, effective dosage and secondary effects of sacha inchi´s (Plukenetia volúbilis L oil on the lipid profiles of patients with hypercholesterolemia. We included 24 patients of ages 35 to 75, to whom we measured total cholesterol (TC, HDL, triglycerides (Tg, glucose (G, non-esterified fatty acids (NEFA and insulin (I levels in blood, then we randomized them to receive sacha inchi oil orally 5 ml or 10 ml of a suspension of sacha inchi oil (2gr/5ml for four months. The oil intake produced a decrease in the mean values of TC, and NEFA, and a rise in HDL in both subgroups. The subgroup receiving 10 ml was associated to an increase in the insulin levels. Sacha inchi oil appears to have beneficial effects on the lipid profile of patients with dyslipidemia, but their efficacy and security should be evaluated in randomized clinical trials.

    Full Text Available The corrosion of copper in the presence of volatile organic acids is frequent. Thus, for example, it is known that failures by corrosion of the copper tubes take place in the air conditioning equipment, caused by volatile organic acids emitted by oils used in their manufacturing. Another frequent case is the corrosion of copper objects caused by the acids emitted by the materials used in packing, wood and resins, amongst others. This communication presents the corrosion results of copper exposed to 100% relative humidity and different concentrations (10-300 ppm of formic [HCOOH], acetic [CH3COOH], propionic [CH3CH2COOH] and butyric [CH3(CH22COOH] acid vapours, for short exposure times. The techniques used were gravimetric analysis, scanning electron microscopy (SEM and X-ray diffraction (XRD.

    Full Text Available Ceramic cutting inserts coated with ten-fold alternating micro- and nanocrystalline diamond (MCD/NCD layers grown by hot filament chemical vapor deposition (CVD were tested in the machining of an Al based metallic matrix composite (MMC containing 15 vol % Al2O3 particles. Inserts with total coating thicknesses of approximately 12 µm and 24 µm were produced and used in turning: cutting speed (v of 250 to 1000 m·min−1; depth of cut (DOC from 0.5 to 3 mm and feed (f between 0.1 and 0.4 mm·rev−1. The main cutting force increases linearly with DOC (ca. 294 N per mm and with feed (ca. 640 N per mm·rev−1. The thicker coatings work within the following limits: DOC up to 1.5 mm and maximum speeds of 750 m·min−1 for feeds up to 0.4 mm·rev−1. Flank wear is predominant but crater wear is also observed due to the negative tool normal rake. Layer-by-layer wear of the tool rake, and not total delamination from the substrate, evidenced one of the advantages of using a multilayer design. The MCD/NCD multilayer diamond coated indexable inserts have longer tool life than most CVD diamond systems and behave as well as most polycrystalline diamond (PCD tools.

    In this paper, differences between the 24-h average PM{sub 10} concentrations of Wedding {sup {beta}}-gauge monitor and Andersen or Wedding hi-vol sampler were studied. When the deliquescent point is not exceeded, PM{sub 10} concentrations of the {sup {beta}}-gauge are close to those of the manual samplers. The ratio of {sup {beta}}-gauge PM{sub 10} to Andersen PM{sub 10} and Wedding PM{sub 10} is 1.08{+-}0.06 and 1.09{+-}0.12, respectively. However, when the deliquescent point is exceeded, water absorption by the inorganics of aerosols leads to higher PM{sub 10} concentrations of the {sup {beta}}-gauge compared to those of the manual sampler. The ratio of {sup {beta}}-gauge PM{sub 10} to Andersen PM{sub 10} and Wedding PM{sub 10} is 1.21{+-}0.22 and 1.27{+-}0.15, respectively. However, due to evaporation of water from the aerosols collected on the filter tape of the {sup {beta}}-gauge, differences in PM{sub 10} concentrations are much less than theoretically calculated.

    Full Text Available Aldose Reductase (AR is the polyol pathway key enzyme which converts glucose to sorbitol. High glucose availability in insulin resistant tissues in diabetes leads into an accumulation of sorbitol, which has been associated with typical chronic complications of this disease, such as neuropathy, nephropathy and retinopathy. In this study, 71 flavonoids AR inhibitors were subjected to two methods of SAR to verify crucial substituents. The first method used the PCA (Principal Component Analysis to elucidate physical and chemical characteristics in the molecules that would be essential for the activity, employing VolSurf descriptors. The rate obtained explained 53% of the system total variance and revealed that a hydrophobic-hydrophilic balance in the molecules is required, since very polar or nonpolar substituents decrease the activity. Artificial Neural Networks (ANNs was also employed to determine key substituents by evaluating substitution patterns, using NMR data. This study had a high success rate (85% accuracy in the training set and 88% accuracy in the test set and showed polihydroxilations are essential for high activity and methoxylations and glicosilations primarily at positions C7, C3' and C4' decrease the activity.

    2013-01-01

    The CONNECT-OptiVol study is designed to investigate whether wireless fluid monitoring using OptiVol alerts as well as implantable cardioverter-defibrillator (ICD) remote monitoring (RM) reduces cardiac decompensations and health care utilization in ICD patients, as compared to standard clinical care. Patients undergoing implantation of wireless telemetry-enabled dual chamber (ICD-DR) or cardiac resynchronization therapy/defibrillator (CRT-D) devices with the OptiVol feature are eligible for the study. In a randomized fashion, OptiVol function, its audible alert as well as its remote alert, and other ICD RM alerts are switched ON or OFF. The primary study objective is to estimate an improvement of heart failure status. The primary endpoint is measured as a prolongation of the time to first hospitalization due to worsened heart failure. The secondary objectives are to estimate: a reduction of the time from event to clinical decision, a reduction of the rate of health care utilization, and improved quality of life (QoL) measures (secondary endpoints). The study is designed as a single center pilot study with 180 patients randomized 1:1 to the two study arms. The CONNECT-OptiVol study aims to answer whether wireless fluid monitoring integrated into RM may reduce cardiac decompensations and health care utilization in ICD patients. The results can be used to adequately power future studies evaluating the benefit of these features. Study enrollment has been completed, and follow-up is expected to be finished in September 2012.

    Lewis, BE

    2003-10-07

    The Gunite and Associated Tanks (GAAT) Remediation Project was the first of its kind performed in the United States. Robotics and remotely operated equipment were used to successfully transfer almost 94,000 gal of remote-handled transuranic sludge containing over 81,000 Ci of radioactive contamination from nine large underground storage tanks at the Oak Ridge National Laboratory (ORNL). The sludge was transferred with over 439,000 gal of radioactive waste supernatant and {approx}420,500 gal of fresh water that was used in sluicing operations. The GAATs are located in a high-traffic area of ORNL near a main thoroughfare. Volume 1 provides information on the various phases of the project and describes the types of equipment used. Volume 1 also discusses the tank waste retrieval performance and the lessons learned during the remediation effort. Volume 2 consists of the following appendixes, which are referenced in Vol. 1: A--Background Information for the Gunite and Associated Tanks Operable Unit; B--Annotated Bibliography; C--GAAT Equipment Matrix; D--Comprehensive Listing of the Sample Analysis Data from the GAAT Remediation Project; and E--Vendor List for the GAAT Remediation Project. The remediation of the GAATs was completed {approx}5.5 years ahead of schedule and {approx}$120,435K below the cost estimated in the Remedial Investigation/Feasibility Study for the project. These schedule and cost savings were a direct result of the selection and use of state-of-the-art technologies and the dedication and drive of the engineers, technicians, managers, craft workers, and support personnel that made up the GAAT Remediation Project Team.

    20 vol.% cubic boron nitride (cBN) dispersoid reinforced NiCrAl matrix nanocomposite coating was prepared by cold spray using mechanically alloyed nanostructured composite powders. The as-sprayed nanocomposite coating was annealed at a temperature of 750 °C to enhance the inter-particle bonding. Microstructure of spray powders and coatings was characterized. Vickers microhardness of the coatings was measured. Two-body abrasive wear behavior of the coatings was examined on a pin-on-disk test. It was found that, in mechanically alloyed composite powders, nano-sized and submicro-sized cBN particles are uniformly distributed in nanocrystalline NiCrAl matrix. Dense coating was deposited by cold spray at a gas temperature of 650 °C with the same phases and grain size as those of the starting powder. Vickers hardness test yielded a hardness of 1063 HV for the as-sprayed 20 vol.% cBN-NiCrAl coating. After annealed at 750 °C for 5 h, unbonded inter-particle boundaries were partially healed and evident grain growth of nanocrystalline NiCrAl was avoided. Wear resistance of the as-sprayed 20 vol.% cBN-NiCrAl nanocomposite coating was comparable to the HVOF-sprayed WC-12Co coating. Annealing of the nanocomposite coating resulted in the improvement of wear resistance by a factor of ~33% owing to the enhanced inter-particle bonding. Main material removal mechanisms during the abrasive wear are also discussed.

    Full Text Available The objective of this study was to compare the sensory quality and the volatile compound profile of new varieties of Capsicum chinense pepper (CNPH 4080 a strain of'Cumari-do-Pará' and BRS Seriema with a known commercial variety (Biquinho. Volatiles were isolated from the headspace of fresh fruit by SPME and identified by GC-MS. Pickled peppers were produced for sensory evaluation. Aroma descriptors were evaluated by Check-All-That-Apply (CATA method, and the frequency data were submitted to Correspondence Analysis. Flavor acceptance was assessed by hedonic scale and analyzed by ANOVA. BRS Seriema showed the richest volatile profile, with 55 identified compounds, and up to 40% were compounds with sweet aroma notes. CNPH 4080 showed similar volatile profile to that of Biquinho pepper, but it had higher amounts of pepper-like and green-note compounds. The samples did not differ in terms of flavor acceptance, but they showed differences in aroma quality confirming the differences found in the volatile profiles. The C. chinense varieties developed by Embrapa proved to be more aromatic than Biquinho variety, and were well accepted by the judges.O objetivo deste estudo foi comparar a qualidade sensorial e o perfil de compostos voláteis de novas variedades de pimenta Capsicum (CNPH 4080, uma linhagem de cumari-do-pará, e BRS Seriema, com uma variedade comercial (Biquinho.

    Full Text Available Os compostos voláteis de três cultivares de manga (Haden, Tommy-Atkins e Keitt procedentes do Estado de São Paulo, foram isolados por uma técnica de headspace dinâmico, envolvendo sucção em polímero poroso. A separação da mistura complexa de voláteis foi efetuada por cromatografia gasosa de alta resolução. Alguns compostos voláteis foram identificados por cromatografia gasosa-espectrometria de massas e índices de Kovats. Os hidrocarbonetos monoterpênicos foram os compostos mais abundantes no headspace das amostras. Car-3-eno foi o componente majoritário dos cultivares Haden e Keitt, enquanto a Tommy-Atkins mostrou predominância de car-3-eno e alfa-pineno. Outros compostos identificados foram alfa-fencheno, alfa-canfeno, p-cimeno, beta-mirceno, beta-felandreno, limoneno, alfa-terpinoleno, beta-cariofileno e alfa-humuleno. Os três lotes analisados para cada cultivar mostraram grande homogeneidade, não havendo diferença significativa ao nível de 5%.The volatile compounds of three mango cultivars (Haden, Tommy-Atkins and Keitt, from the State of São Paulo, were isolated by a dynamic headspace technique involving suction on a porous polymer. The complex mixture of volatile compounds was separated by high-resolution gas chromatography. Some volatiles were identified by gas chromatography-mass spectrometry and Kovats Indices. The monoterpene hydrocarbons were the most abundant in the headspace of the fruits. Car-3-ene was the major component of the cultivars Haden and Keitt, while the Tommy Atkins mango exhibited predominance of two constituents, car-3-ene and alpha-pinene. Other identified compounds were alpha-fenchene, alpha-camphene, p-cimene, beta-mircene, beta-phellandrene, limonene, alpha-terpinolene, beta-caryophyllene e alpha-humulene. Samples of the same cultivar demonstrated great homogeneity, with no statistically significant difference being observed among the three lots analyzed for each cultivar.

    1992-01-01

    The effects of casting conditions and deformation processing on the mechanical properties of unreinforced A356 aluminum and A356-20 vol pct SiC composite were investigated by tensile properties in these compounds fabricated by either sand casting or squeeze casting techniques followed by hot working to 33, 50, 90, and 95 percent reductions. The evolution of the microstructure and values of tensile properties were evaluated for the cast materials in each of the hot worked conditions. It was found that, while the deformation processing of the sand-cast composite resulted in banding of the Al and SiC particles within the microstructure, such features were not observed in the squeeze-cast microstructure. The tensile strengths of the squeeze cast materials was found to be higher than those of the sand cast materials, for both the unreinforced and composite samples, while increased amounts of deformation were found to improve the ductility of the composite.

    Full Text Available The corrosion behavior of 6061/Al-15 vol. pct. SiC(p composite and 6061 Al base alloy was investigated in a sodium hydroxide solution. The electrochemical parameters were derived from potentiodynamic polarization and electrochemical impedance spectroscopic (EIS techniques. The results showed that the corrosion resistance of the composite was lower than that of the base alloy in selected corrosion media. The corrosion rates of both the composite and the base alloy increased with the increase in the concentration of sodium hydroxide and also with the increase in temperature. The surface morphology of the metal surface was investigated using scanning electron microscope (SEM. Activation energy was evaluated using Arrhenius equation, and enthalpy of activation and entropy of activation values were calculated using transition state equation.

    Full Text Available La fibrosis pulmonar idiopática (FPI es una enfermedad que se caracteriza por presentar un compromiso pulmonar de tipo restrictivo, resultante de una reducción en la complacencia pulmonar secundaria a fibrosis difusa. En el enfisema, la pérdida de elasticidad pulmonar y el colapso de las vías aéreas periféricas generan obstrucción e hiperinflación. El efecto simultáneo que ambas enfermedades producen sobre la fisiología pulmonar no es del todo claro y se han descripto volúmenes pulmonares normales o casi normales. Presentamos 4 pacientes de sexo masculino de 64, 60, 73 y 70 años, con antecedentes de tabaquismo e historia de disnea progresiva, tres de ellos con grave limitación en su calidad de vida al momento de la consulta. En la tomografía de tórax de alta resolución todos los pacientes presentaban signos de enfermedad intersticial pulmonar avanzada, con cambios de tipo fibrótico con predominio basal y subpleural, que coexistían con enfisema centroacinar con predominio en lóbulos superiores. Uno de ellos tuvo confirmación diagnóstica de ambas condicioes por biopsia pulmonar a cielo abierto. En los cuatro pacientes la espirometría y volúmenes pulmonares fueron normales, pero tenían importante compromiso del intercambio gaseoso evaluado mediante el test de caminata de 6 minutos.

    Full Text Available The objective of this work was to identify and verify the influence of time and temperature on the volatile compounds profile of fresh cut peki. Peki fruits were washed, sanitized, their kernels were extracted, and they were packaged and stored for 15 days at 0, 5, and 10 °C and 6 days at 22 °C. The volatiles compounds were analyzed by GC - MS. Ethyl hexanoate and ethyl octanoate were found in higher percentages, 63 and 16.3%, respectively. The determined volatiles were not influenced by the storage period. Hexanoic acid, ethyl 2-octenoate and ethyl decanoate were not influenced by the different temperatures. The temperatures 0, 5, and 10 °C did not influence ethyl hexanoate, ethyl 2-hexenoate and ethyl octanoate either. In addition, the temperatures 5, 10, and 22 °C did not influence ethyl hexanoate, cis-β-ocimene and ethyl octanoate. The temperature of 22 °C determined higher percentages of ethyl hexanoate and lower percentages of ethyl octanoate, in comparison to the temperature of 0 °C, and higher percentages of ethyl 2-hexenoate in comparison to the temperatures of 0, 5, and 10 °C. The temperature of 5 °C determined higher percentage of cis-β-ocimene when compared with the temperature of 0 °C. The storage temperatures of 0 and 5 °C were the most appropriate for the conservation.O objetivo do trabalho foi identificar e verificar a influência do tempo e da temperatura sobre o perfil dos compostos voláteis de pequi minimamente processado.

    Full Text Available The creep behavior of a powder metallurgy (PM Al6061-15 vol % SiCw metal matrix composite has been studied. This behavior has been compared to that of 6061Al cast alloy and 6061Al PM alloy. The creep response of the PM unreinforced alloy is better than that of the cast 6061Al alloy. Similarly, the behavior of the composite is better than that of the PM unreinforced alloy. Two microstructural factors have been considered the responsible ones of this improvement. The first one is the dispersion of Al2O3 oxide particles of nanometric scale. The second one, is the presence of the SiC whisker reinforcement of micrometric scale. Despite the similar strengthening effect, the intrinsic nature of the reinforcing mechanism is, however, different for each type of particle due to the different microstructural scale.Se ha realizado un estudio de las propiedades en fluencia del material compuesto pulvimetalúrgico Al6061-15 vol % SiCw. Su comportamiento se ha comparado con el de la aleación Al6061 pulvimetalúrgica y la aleación Al6061 de colada. El comportamiento del material pulvimetalúrgico sin reforzar mejora respecto al del material de colada. Al mismo tiempo, el del material compuesto mejora respecto al comportamiento del material pulvimetalúrgico sin reforzar. Se consideran dos factores microestructurales como los principales responsables de la mejora de las propiedades en fluencia de este material compuesto. Por un lado, las partículas de Al2O3 de tamaño nanométrico y, por otro, las partículas de fibra corta cerámicas de SiC de tamaño micrométrico. Aunque ambos tipos de partículas dan lugar a un efecto de refuerzo similar, los mecanismos intrínsecos asociados a la presencia de estas partículas tienen una naturaleza diferente debido a la diferencia en la escala microestructural.

A análise de cromatografia gasosa acoplada à espectrometria de massas (CG-EM dos constituintes voláteis mostrou que piridina, pirazina e derivados, furfural e derivados são os principais constituintes voláteis dos cafés analisados. Mostrou ainda que não é possível diferenciar os três tipos de café pelos compostos dominantes (concentração acima de 1% no aroma. Foi observado também que a torra afeta sensivelmente os resultados, sendo que a torra americana, usada normalmente na prova da xícara para classificação sensorial de cafés, produz alguns voláteis de forte impacto no aroma que não aparecem na torra média nem na forte, além de apresentar concentrações dos componentes mais comuns muito diferentes daquelas observadas nas outras duas torras.

    H.E.S.S. observations of the old-age (>10{sup 4} yr; {approx} 0.5 degree diameter) composite supernova remnant (SNR)W28 reveal very high energy (VHE) {gamma}-ray emission situated at its northeastern and southern boundaries. The northeastern VHE source (HESS J1801-233) is in an area where W 28 is interacting with a dense molecular cloud, containing OH masers, local radio and X-ray peaks. The southern VHE sources (HESS J1800-240 with components labeled A, B and C) are found in a region occupied by several HII regions, including the ultracompact HII region W 28A2. Our analysis of NANTEN CO data reveals a dense molecular cloud enveloping this southern region, and our reanalysis of EGRET data reveals MeV/GeV emission centered on HESS J1801-233 and the northeastern interaction region.

    In this work, a new, fast and reliable methodology using a digitally controlled microextraction by packed sorbent (eVol(®)-MEPS) followed by ultra-high pressure liquid chromatography (UHPLC) analysis with photodiodes (PDA) detection, was developed to establish the urinary profile levels of four putative oxidative stress biomarkers (OSBs) in healthy subjects and patients evidencing cardiovascular diseases (CVDs). This data was used to verify the suitability of the selected OSBs (uric acid-UAc, malondialdehyde-MDA, 5-(hydroxymethyl)uracil-5-HMUra and 8-hydroxy-2'-deoxyguanosine-8-oxodG) as potential biomarkers of CVDs progression. Important parameters affecting the efficiency of the extraction process were optimized, particularly stationary phase selection, pH influence, sample volume, number of extraction cycles and washing and elution volumes. The experimental conditions that allowed the best extraction efficiency, expressed in terms of total area of the target analytes and data reproducibility, includes a 10 times dilution and pH adjustment of the urine samples to 6.0, followed by a gradient elution through the C8 adsorbent with 5 times 50 µL of 0.01% formic acid and 3×50 µL of 20% methanol in 0.01% formic acid. The chromatographic separation of the target analytes was performed with a HSS T3 column (100 mm × 2.1 mm, 1.7 µm in particle size) using 0.01% formic acid 20% methanol at 250 µL min(-1). The methodology was validated in terms of selectivity, linearity, instrumental limit of detection (LOD), method limit of quantification (LOQ), matrix effect, accuracy and precision (intra-and inter-day). Good results were obtained in terms of selectivity and linearity (r(2)>0.9906), as well as the LOD and LOQ, whose values were low, ranging from 0.00005 to 0.72 µg mL(-1) and 0.00023 to 2.31 µg mL(-1), respectively.

    The compression properties and electrical conductivity of in-situ 20 vol.% nano-sized TiCx/Cu composites fabricated via combustion synthesis and hot press in Cu-Ti-CNTs system at various particles size and morphology were investigated. Cubic-TiCx/Cu composite had higher ultimate compression strength (σUCS), yield strength (σ0.2), and electric conductivity, compared with those of spherical-TiCx/Cu composite. The σUCS, σ0.2, and electrical conductivity of cubic-TiCx/Cu composite increased by 4.37%, 20.7%, and 17.8% compared with those of spherical-TiCx/Cu composite (526 MPa, 183 MPa, and 55.6% International Annealed Copper Standard, IACS). Spherical-TiCx/Cu composite with average particle size of ~94 nm exhibited higher ultimate compression strength, yield strength, and electrical conductivity compared with those of spherical-TiCx/Cu composite with 46 nm in size. The σUCS, σ0.2, and electrical conductivity of spherical-TiCx/Cu composite with average size of ~94 nm in size increased by 17.8%, 33.9%, and 62.5% compared with those of spherical-TiCx/Cu composite (417 MPa, 121 MPa, and 40.3% IACS) with particle size of 49 nm, respectively. Cubic-shaped TiCx particles with sharp corners and edges led to stress/strain localization, which enhanced the compression strength of the composites. The agglomeration of spherical-TiCx particles with small size led to the compression strength reduction of the composites.

  9. Effects of CO2 pneumoperitoneum on blood flow vol-ume of abdominal organs of rabbits with controlled hem-orrhagic shock and liver impact injuries

    Objective: To investigate the effects of CO2 pneumo-peritoneum on blood flow volume of abdominal organs of rabbits with controlled hemorrhagic shock model and liver impact injuries.Methods: After controlled hemorrhagic shock and liver impact injuries, the rabbit model was established. Eighteen rabbits subjected to hemorrhagic shock and liver impact inju-ries were divided into 3 groups randomly according to the volume of lost blood: light hemorrhagic shock (blood loss volume was 10%, 6 ml/kg), moderate hemorrhagic shock (20%, 12 ml/kg) and severe hemorrhagic shock (40%, 22 ml/kg). Intraabdominal pressures of CO2 pneumoperitoneum was 10 mmHg. Color-labeled microspheres were used to mea-sure the blood flow volume of the liver, kidney and stomach before pneumoperitoneum at 30 minutes and 2 hours after pneumoperitoneum and 30 minutes after deflation. And the mortality and hepatic traumatic condition of rabbits were recorded.Results: Of the 18 rabbits, there were 9 with liver impact injuries at Grade Ⅰ, 8 at Grade Ⅱ and Ⅰ at Grade Ⅲ (according to AIS-2005). The mortality rate in light hemorrhagic shock group was 33.33%, and that in moderate or severe hemor-rhagic shock group was 100% within 30 minutes and 2 hours after pneumoperitoneum, respectively. The blood flow vol-ume in the organs detected decreased at 30 minutes under pneumoperitoneum in light and moderate hemorrhagic shock groups. At the same time, the blood flow volume of the liver in moderate hemorrhagic shock group decreased more sig-nificantly than that in light hemorrhagic shock group.Conclusions: The blood flow volume of abdominal organs in rabbits is decreased obviously under CO2 pneumoperitoneum, with fairly high mortality rate. It is be-lieved that CO2 pneumoperitoneum should cautiously be used in abdominal injury accompanied with hemorrhagic shock, especially under non-resuscitation conditions.

    Energy Technology Data Exchange (ETDEWEB)

    2004-07-12

    IBIS (massively parallelized version 2) is a comprehensive model of terrestrial biospheric processes, and includes land surface physics, canopy physiology, plant phenology, vegetation dynamics and competition, and carbon cycling. The land surface module simulates the energy, water, carbon and momentum balance of soil/vegetation/atmospheric system on a short time step consistent with general circulation models (20-60 minutes). The module includes two vegetation layers (trees, and grasses and shrubs) and six soil layers to simulate soil temperature, soil water, and soil ice content over a total depth of 4 m. Physiologically-based formulations of C3 and C4 photosynthesis (Farquhar. et al., 1980), stomatal conductance (Collatz, et al., 1992; Collatz, et al., 1991) and respiration (Amthor, 1984) are used to simulate canopy gas exchange processes. Budburst and senescence depend on climatic factors following the empirical algorithm presented by Botta, et al. (2000). The annual carbon balance allows the vegetation dynamics submodel to predict the maximum leaf area index and biomass for 12 plant functional types, which compete for light and water. IBIS represents vegetation dynamics using very simple competition rules. The relative abundance of the 12 platn functional types in each grid cell changes in time according to their ability to photosynthesize and use water, IBIS simulates carbon cycling through vegetation, litter and soil organic matter. The soil biogeochemistry model of Verbene, et al. (1990). The total below-ground carbon in the first meter of soil is divided into pools characterized by their residence time: from a few hours for the microbal biomass to more than 1000 years for stabilized organic matter. Decomposition rates of litter and soil carbon depend on soil temperature and soil moisture.

    Full Text Available Changes in the profile of volatile compounds after the heating of refined soybean oil without adding antioxidants, and treated with quercetin and chlorogenic acid (5-CQA were investigated by GC/FID, GC/MS, and GC/SNIFFING. The heating temperature of the oil sample was 20 °C for the first minute, and then it was increased up to 160 °C at the rate of 10 °C min-1. The final temperature was kept for 10 minutes. 19 volatiles were identified in the heated samples without antioxidants. Medium-chain carbonyls predominated in the volatile fraction, mainly 2-heptenal, 2,4-heptadienal and 2,4-decadienal. Around 11 to 15 volatile compounds were detected in the heated samples treated with 5-CQA and quercetin, respectively. 5-CQA was not very efficient in delaying the formation of oxidative volatile compounds. The samples quercetin presented lower proportion of carbonyls with C6-C9.. The GC peak area data were used as an approach to estimate the relative content of each volatile compound and indicate that the samples treated with quercetin (p As alterações no perfil de compostos voláteis, após o aquecimento de óleo de soja refinado sem a adição de antioxidantes e tratado previamente com quercetina e ácido clorogênico (5-ACQ, foram investigadas através da CG/DIC, CG/EM e CG/SNIFFING. A temperatura de aquecimento do óleo foi de 20 °C no primeiro minuto e aumentada até 160 °C à taxa de 10 °C min-1. A temperatura final foi mantida por 10 minutos. Um total de 19 compostos voláteis foi identificado nas amostras aquecidas sem a adição de antioxidantes. As carbonilas de cadeia média predominaram na fração volátil.

    2007-07-01

    To investigate the change of global and regional cerebral blood flow after heart transplantation (HT) in congestive heart failure (CHF) patients. Twenty-one patients with CHF who underwent HT (45{+-}12 yrs, M/F=19/2) and 10 healthy volunteers (39{+-}13 yrs, M/F = 7/3) were prospectively included. All patients underwent echocardiography and radionuclide angiography including brain and aorta with brain SPECT which was performed after iv bolus injection of Tc-99m ECD (740MBq) before (175{+-}253 days) and after (129{+-}82 days) HT. Patients were divided into two groups according to the interval between HT and postoperative SPECT [early follow-up (f/u): <6 mo, n=14; late f/u: >6 mo, n=7]. Global CBF (gCBF) of bilateral hemispheres were calculated by Patlak graphical analysis. Absolute rCBF map was obtained from brain SPECT by Lassen's correction algorithm. Age-corrected voxel-based analysis using SPM2 and automatic VOl analysis were performed to assess the rCBF change. Cardiac ejection fraction of all patients improved after HT (20.8%{yields}64.0%). gCBF was reduced compared to normal before HT (35.7{+-}3.9 vs. 49.1{+-}3.0 ml/100g/min; p<0.001) and improved postoperatively (46.6{+-}5.4, p<0.001). The preoperative gCBFs of early and late f/u group were not different (34.6{+-}3.2 vs. 38.0{+-}4.4, p=0.149) but postoperative gCBF (43.9{+-}3.7) of late f/u group was higher than those (52.0{+-}4.0) of early f/u group (p<0.001). On voxel-based analysis, preoperative rCBF was reduced in entire brain but most severely in bilateral superior and inferior frontal cortex, supplementary motor area, precuneus and anterior cingulum, compared to normals (uncorrected p<0.001). After HT, rCBF of these areas improved more significantly in late f/u group than in early f/u group but still lower than normals. Global CBF was significantly reduced in CHF patients and improved after HT. rCBFs of the frontal cortex, precuneus and cingulum were most severely reduced and slowly improved after

    Full Text Available RESUMO Aleloquímicos são substâncias liberadas por certas espécies vegetais no ambiente que influenciam a germinação e o desenvolvimento de outras plantas. O objetivo desse estudo foi avaliar o potencial fitotóxico de Cleome guianensis Aubl., bem como determinar o grau de estresse oxidativo causado em Senna occidentalis L. Para isso, o óleo das folhas de C. guianensis, nas concentrações 0,5 µg/mL, 1,0 µg/mL, 2,5 µg/mL e 5,0 µg/mL, em solução de 5 ml foi testado em bioensaios de germinação e de crescimento da raiz primária e do hipocótilo de S. occidentalis. Os indivíduos de S. occidentalis foram macerados, homogeneizados e submetidos a ensaios de quantificação da catalase, peroxidase, SOD e de peroxidação lipídica. Os resultados indicam que todas as concentrações do óleo volátil causaram um efeito negativo sobre a germinação e crescimento de S. occidentalis. Na concentração 5,0 µg/mL, houve 56% de inibição da germinação e 83% de inibição de crescimento do hipocótilo. Ainda, o óleo aumentou a atividade das enzimas induzidas pelo estresse oxidativo catalase, peroxidase e superóxido dismutase (SOD. Quanto à peroxidação lipídica, o óleo nas concentrações 1,0 µg/mL, 2,5 µg/mL e 5,0 µg/mL aumentou a produção de malondialdeído. Sendo assim, conclui-se que C. guianensis apresenta aleloquímicos que influenciam na germinação e no crescimento de S. occidentalis, além de aumentar a atividade das enzimas catalase, peroxidase, SOD e a produção de malondialdeído em S. occidentalis. Dessa forma, sugere-se a realização de estudos sobre o perfil químico do óleo a fim de descobrir as substâncias responsáveis por tais resultados e consolidar o potencial fitotóxico de C. guianensis.

    In the years from 2001 to 2006, Guseinov and his coworkers published 40 articles on the derivation and application of one-range addition theorems. In E. J. Weniger, Extended Comment on ``One-Range Addition Theorems for Coulomb Interaction Potential and Its Derivatives'' by I. I. Guseinov (Chem. Phys. Vol. 309 (2005), pp. 209 - 213), arXiv:0704.1088v2 [math-ph], it was argued that Guseinov's treatment of one-range addition theorems is at best questionable and in some cases fundamentally flawed. In I. I. Guseinov, Extended Rejoinder to "Extended Comment on "One-Range Addition Theorems for Coulomb Interaction Potential and Its Derivatives'' by I. I. Guseinov (Chem. Phys. and Vol. 309 (2005)'', pp. 209-213), arXiv:0706.0975v2 [physics.chem-ph], these claims were disputed. To clarify the situation, the most serious mathematical flaws in Guseinov's treatment of one-range addition theorems are discussed in more depth.

SiC(p) composite and its base alloy were studied at different temperatures in acid mixture medium containing varying concentrations of hydrochloric acid and sulphuric acid using Tafel extrapolation technique and ac impedance spectroscopy (EIS). The effect of inhibitor concentration, temperature and concentration of the acid mixture media on the inhibitor action was investigated. It was found that inhibition efficiencies increase with the increase in inhibitor concentration, but decrease with the increase in temperature and with the increase in concentration of the acid media. Thermodynamic parameters for dissolution process were determined. The adsorption of DMABT on both the composite and base alloy was found to be through physisorption obeying Freundlich adsorption isotherm.

    Casal, M. D.

    Full Text Available The study of the weathering of two bituminous coals stored at the INCAR stockyard and its influence on coke quality is presented. These coals of similar rank are present in industrial blends used by the Corporación Siderúrgica Integral (CSI for the production of blast-furnace coke. Of all the techniques used to determine the degree of weathering, via thermoplastic properties, Gieseler plastometry was found to be the most sensitive. Coking tests were carried out in the semi-industrial coking plant at INCAR. The effect of weathering on each coal series is completely different. Weathering produces a loss of maximum fluidity accompanied by a decrease in aliphatic hydrogen in both coals. However, the loss rate is different in each case. Coke quality clearly decreases in one, while in the other improves at first but then gradually deteriorates. An improvement in coke quality due to weathering not only affects some high-volatile coals as it is well known but also medium volatile coals.

    Se presenta el estudio de la alteración meteórica de dos carbones bituminosos con contenido medio de materia volátil y de diferente origen geográfico, que han sido almacenados a la intemperie en el Parque del INCAR. Ambos carbones son constituyentes de las mezclas de carbones coquizables utilizadas por la Corporación Siderúrgica Integral (CSI para la producción de coque de horno alto. Entre las técnicas utilizadas para detectar el grado de meteorización de dichos carbones, la fluidez máxima Gieseler es el indicador más sensible para detectar la pérdida de propiedades plásticas. Ambas series de carbones presentan diferente comportamiento frente a la meteorización. Si bien la alteración meteórica provoca una pérdida de fluidez máxima con el tiempo de almacenamiento, debido a una pérdida de hidrógeno alifático en los dos carbones, ésta se produce a diferente velocidad. Estas diferencias se ponen de manifiesto en la calidad de los coques

    This work aims to contribute to a further understanding of the fundamentals of crystallographic slip and grain boundary sliding in the γ-TiAl Ti–45Al–2Nb–2Mn (at%)–0.8 vol%TiB{sub 2} intermetallic alloy, by means of in situ high-temperature tensile testing combined with electron backscatter diffraction (EBSD). Several microstructures, containing different fractions and sizes of lamellar colonies and equiaxed γ-grains, were fabricated by either centrifugal casting or powder metallurgy, followed by heat treatment at 1300 °C and furnace cooling. in situ tensile and tensile-creep experiments were performed in a scanning electron microscope (SEM) at temperatures ranging from 580 °C to 700 °C. EBSD was carried out in selected regions before and after straining. Our results suggest that, during constant strain rate tests, true twin γ/γ interfaces are the weakest barriers to dislocations and, thus, that the relevant length scale might be influenced by the distance between non-true twin boundaries. Under creep conditions both grain/colony boundary sliding (G/CBS) and crystallographic slip are observed to contribute to deformation. The incidence of boundary sliding is particularly high in γ grains of duplex microstructures. The slip activity during creep deformation in different microstructures was evaluated by trace analysis. Special emphasis was placed in distinguishing the compliance of different slip events with the Schmid law with respect to the applied stress.

  15. Effects of the deep rolling process on the surface roughness and properties of an Al-3vol%SiC nanoparticle nanocomposite fabricated by mechanical milling and hot extrusion

    Sattari, Sajjad; Atrian, Amir

    2017-07-01

    Deep rolling is one of the most widely used surface mechanical treatments among several methods used to generate compressive residual stress. This process is usually used for axisymmetric components and can lead to improvements of the surface quality, dimensional accuracy, and mechanical properties. In this study, we deduced the appropriate deep rolling parameters for Al-3vol%SiC nanocomposite samples using roughness and microhardness measurements. The nanocomposite samples were fabricated using a combination of mechanical milling, cold pressing, and hot extrusion techniques. Density measurements indicated acceptable densification of the samples, with no porosity. The results of tensile tests showed that the samples are sufficiently strong for the deep rolling process and also indicated near 50% improvement of tensile strength after incorporating SiC nanoparticle reinforcements. The effects of some important rolling parameters, including the penetration depth, rotation speed, feed rate, and the number of passes, on the surface quality and microhardness were also investigated. The results demonstrated that decreasing the feed rate and increasing the number of passes can lead to greater surface hardness and lower surface roughness.

    Full Text Available Se diseñó, construyó y operó una unidad de electrodiálisis para estudiar experimentalmente la recuperación como ácido acético del acetato producido durante la digestión anaerobia de desechos orgánicos, usando soluciones acuosas de acetato de sodio a diferentes concentraciones (5 g/l, 15 g/l y 30 g/l para simular el licor de fermentación anaerobia. La electrodiálisis se llevó a cabo aplicando 8 diferentes voltajes a la unidad y monitoreando periódicamente el comportamiento de las variables principales del proceso. La tasa máxima de producción de ácido acético lograda fue de 1674 mg/l y se encontró que esta fue proporcional al voltaje aplicado, caudal de licor de fermentación alimentado a la unidad y a la densidad de corriente utilizada. El ácido acético se recuperó en agua destilada y adicionalmente en una solución acuosa de etanol. La electrodiálisis resultó ser una alternativa técnicamente viable en principio, para la producción de ácidos grasos volátiles, pues los resultados obtenidos demuestran que es posible hacerlo con relativa facilidad.

  4. Transformation of Graphical ECA Policies into Executable PonderTalk Code

    Science.gov (United States)

    Romeikat, Raphael; Sinsel, Markus; Bauer, Bernhard

    Rules are becoming more and more important in business modeling and systems engineering and are recognized as a high-level programming paradigma. For the effective development of rules it is desired to start at a high level, e.g. with graphical rules, and to refine them into code of a particular rule language for implementation purposes later. An model-driven approach is presented in this paper to transform graphical rules into executable code in a fully automated way. The focus is on event-condition-action policies as a special rule type. These are modeled graphically and translated into the PonderTalk language. The approach may be extended to integrate other rule types and languages as well.

    Predictors of non-response were investigated in a 15-year follow-up (1981-1996) of 3,481 individuals in a probability sample from the household population of East Baltimore. Demographics (age, sex, race, education, marital status, and unemployment), household factors (living arrangements, household income, household size, and number of children), cultural variables (ancestral ethnicity and foreign language), social variables (social support and networks, committing felony, carrying a weapon, using an alias, and wandering), health factors (physical illness, health insurance, medical assistance, Medicare, receiving disability benefits, social security, and welfare), interviewer's observation, and psychopathologic variables (mental disorders, suicide behavior, comorbidity, and drug use) were collected at baseline in 1981 and in 1982, then linked to follow-up data between 1993 and 1996. A tracing process involving mail, phone, criss-cross directories, motor vehicle administration records, a commercial credit bureau, the state criminal justice system, hospital records, the US National Death Index, and field tracing were used to locate the original sample. A total of 3,066 respondents of the original sample (88.1%) were traced. Non-response was categorized into Sample Mortality (that part of the original sample that died during follow-up), Sample Loss (that part of the original sample that survived but could not be found) and Refusal (that part of the original sample that survived and was found but refused to participate). Stratified analysis and adjusted multiple logistic regression modeling found sample mortality and sample loss were strongly influenced by individual and household variables and by psychopathology. Sample mortality was influenced by specific mental disorders or conditions as mania, drug abuse/dependency, antisocial personality, cognitive impairment, alcohol abuse/dependency, phobia, drug use (except PCP), and comorbidity. Household factors protective against mortality include higher household income, not living as extended members in a married couple family, and living with children in the household. Persons who were unemployed, widowed or single, without high school education, male, and 65 years of age or older were more likely to die. Sample loss was influenced by cognitive impairment, antisocial personality, and cocaine use. Household factors linked to sample loss include living in female-headed families, or non-family households, and living alone. Young nonwhite, divorced/separated, without high school education, and unemployed were also harder to find. Refusal was associated with being white, with incomplete elementary education, living as a spouse in traditional married couple families, or as a child in female-headed families. Psychopathology did not influence refusal.
