    Full Text Available Background: Objectives: To compare misoprostol 600 mcg, oral with carboprost 125 mcg, i.m., in the active management of third stage of labour. Methods: A total of 200 pregnant women of 38-42 weeks of gestation delivering vaginally in the Shivamogga institute of medical sciences, Shivamogga, Karnataka, India were selected for study. 100 women received misoprostol 600 mcg, orally and 100 women received carboprost 125 mcg, i.m. immediately after delivery of baby and cord clamping by the method of randomisation. Results: In the misoprostol group, mean blood loss is 134.9 ml, mean duration of the third stage of labour is 4.07 min and mean fall in hemoglobin is 0.34 g/dl. In the carboprost group, mean blood loss is 123.7 ml, mean duration of the third stage of labour is 3.73 min and mean fall in hemoglobin is 0.28 g/dl. There was no signi and #64257;cant difference between the two groups with regard to the above mentioned factors. There were 5 cases of PPH in the misoprostol group and 3 cases in the carboprost group. 21 cases in the misoprostol group and 14 cases in the carboprost group required additional oxytocics. Unpleasant side effects like diarrhoea and vomiting were more in carboprost group. Conclusion: Oral misoprostol is as effective as carboprost in AMTSL and can be used safely in vaginal deliveries for prevention of PPH, especially in non-institutional deliveries and in places of low resource settings.

    Full Text Available No presente trabalho foi estudada a síntese do TAME sobre zeólitas USY, H-Mordenita, H-ZSM-5 e H-Beta. As reações foram feitas em um reator batelada, a 80oC e pressão de 10 kgf/cm2, utilizando metanol e isoamilenos reativos (2-metil buteno 1 e 2-metil buteno 2, presentes em um corte C5 de retorno petroquímico mono-hidrogenado. Para efeito de comparação, foram realizados testes utilizando a resina ácida Amberlyst 15 como catalisador. Os resultados obtidos mostraram que a zeólita H-Beta possui conversão de isoamilenos, rendimento e seletividade a TAME comparáveis à da resina Amberlyst 15 e muito superiores às demais zeólitas estudadas, nas condições de reação ora empregadas. Aparentemente, as espécies de alumina extra-rede (ALER altamente dispersas presentes na H-Beta interagem com alguns sítios ácidos de Brönsted da rede, fazendo com que estes tenham a sua força ácida aumentada. Isto, juntamente com a adsorção preferencial de metanol, que solvata o próton formando grandes “clusters” de moléculas de metanol, conduzem à maior atividade observada para a síntese do TAME sobre a H-Beta, quando comparada às outras zeólitas estudadas

    Full Text Available O poli (metil azoteto de glicidila - GAP - é um material energético que pode ser utilizado como aglutinante (binder e como plastificante energético em compostos explosivos e propulsores de foguetes. Neste trabalho, foi abordada a síntese do (GAP através da conversão direta da epicloridrina (ECH a GAP. Os reagentes utilizados foram azida de sódio, epicloridrina e vários álcoois extensores de cadeias, o etanodiol, o 1,4-butanodiol, o dietilenoglicol e o glicerol. Alguns parâmetros de operação foram avaliados, como o tempo de reação, a proporção entre os reagentes, dois tipos de solvente e a ordem de adição dos reagentes. A variável observada para a análise foi a massa molecular do GAP. Todos os materiais sintetizados também foram caracterizados por análises de FTIR, UV, RMN, DSC, análise elementar e TGA. Uma maior massa molecular, maior rendimento e uma melhor conversão do grupo azida a GAP foram obtidos com a adição de epicloridrina sobre a azida de sódio e usando DMF como solvente.GAP is an aliphatic polyether that includes hydroxyl groups and highly energetic azide groups. Thus, it is an energetic material that can be used as binder or plasticizing agent in propellants and explosive mixtures. The glycidyl azide polymer (GAP was synthesized and characterized by direct conversion of epichlorohydrin. GAP was synthesized by reaction of sodium azide, epichlorohydrin, and some extensor alcohols. The investigation focused on the effects of some key reaction parameters including reagent proportions, reaction time and two different solvents. The product was characterized by FTIR, UV, NMR, DSC, elemental analysis, TGA and GPC. The species were also evaluated through molecular weight (GPC, glass transition temperature (DSC, ignition time and sensitivity.

    Full Text Available O objetivo deste trabalho foi investigar se doenças foliares do tomateiro (Lycopersicon esculentum podem ser afetadas pela indução de resistência proporcionada pela aplicação de Bacillus subtilis, no solo e nas folhas e aplicação via foliar de acibenzolar-S-metil. A fim de investigar o modo de ação envolvido no controle foi avaliada a atividade de peroxidases nas folhas do tomateiro tratado com os indutores biótico e abiótico. Para se avaliar a severidade das doenças foliares foi avaliado o número de folhas de tomate com algum sintoma de doença e determinado o percentual de folhas doentes em relação ao total de folhas por planta. O aumento significativo da concentração de peroxidases nas plantas tratadas com os indutores, assim como a ausência de controle das doenças no tratamento com pulverização direta de B. subtilis nas folhas, são evidências que sugerem que o mecanismo de controle das doenças em questão está relacionado à resistência induzida.This study was conduced to investigate whether the tomato (Lycopersicon esculentum leaf diseases may be affected by the induction of resistance provided by the application of Bacillus subtilis, soil and leaf and foliar application of Acibenzolar-S-Methyl. In order to investigate the mode of action involved in the control was measured the peroxidases activity in the leaf of tomato treated with inducers biotic and abiotic. To evaluate the severity of foliar diseases has been estimated the number of leaf of tomatoes with symptoms of disease and determinate the percent of disease leaf in the total of leaf per plant. The significant increase in levels of peroxidase activity in plants exposed to treatment with inducers and lack of control of leaf diseases, in direct spray of B. subtilis in the leaves, are evidence that suggest that the mechanism of control diseases in question is related to induction resistance.

    Full Text Available Methyl methacrylate (MMA is a monomer that is polymerized into resin by light and heat, producing a clear, resistant, durable and relatively inert plastic material. Because of these characteristics, MMA is largely used in Medicine as bone cement and in Dentistry, in dental braces and prostheses, thus generating continuous interest in its toxicity. Experimental and clinical studies have documented that monomers may cause a wide range of adverse health effects. The most important occupational exposure route of MMA is by inhalation. This study aims to evaluate the toxicity of MMA to the tracheal epithelium, according to the time of exposure. For this purpose, two experimental groups of rats were exposed to MMA by inhalation under poor ventilation: one group (n = 36 was exposed permanently, and the other (n = 36 was exposed during 8 hours per day, without water and food supply during the exposure period. A control group (n = 8 received normal air supply. Twelve animals of each study group were sacrificed after 5, 8 and 10 days of exposure together with two or four control animals. Twenty-nine (80.5% of the rats continuously exposed to MMA developed inflammation on the tracheal epithelium, as well as 58.33% (n = 21 of those exposed 8 h/day and 87.5% (n = 7 of the control rats. No association was observed between the inflammatory process and MMA exposure; no significant alterations in the tracheal epithelium thickness were observed. Further studies on longer exposure times and analysis of other parameters will have to be conducted to exclude the possibility of tracheal damage by vapors of MMA.O metil metacrilato (MMA é um monômero que se polimeriza em resina pela ação da luz e do calor, transformando-se em plástico claro, resistente e durável, relativamente inerte.

    Full Text Available Foi investigada a eficácia comparativa da pulverização foliar em tomateiro de acibenzolar-S-metil (ASM e Ecolife® na proteção contra Xanthomonas vesicatoria, bem como avaliada a ativação de algumas respostas bioquímicas de defesa de planta. Plantas de tomateiro cv. Santa Cruz Kada foram pulverizadas com acibenzolar S-metil (0,2 g l-1 ASM e uma formulação natural proveniente de biomassa cítrica denominada Ecolife® (5 ml l-1. Quatro dias após as pulverizações, as plantas foram inoculadas com um isolado patogênico de Xanthomonas vesicatoria. Em experimentos de quantificação de doença, a pulverização foliar de Ecolife® e ASM conferiu 39,2% e 47,7% de proteção, respectivamente. A resistência induzida em plantas pulverizadas com ASM e Ecolife® foi evidenciada pelo aumento da atividade de peroxidases (POX e oxidases de polifenóis (PPO, iniciado logo às primeiras horas após as pulverizações, continuando até 12 dias de avaliação. A despeito da tendência de queda nas atividades de amônia-liases de fenilalanina (PAL a partir de 3 dias após as pulverizações, plantas tratadas com ASM e Ecolife® tiveram discreto aumento no acúmulo de lignina, principalmente aquelas pulverizadas com Ecolife® e inoculadas com X. vesicatoria. Teores de fenóis solúveis totais decresceram significativamente, 9 e 12 dias após pulverizações. O aumento nas atividades de POX e PPO poderia resultar em lignificação, a qual estaria associada a uma estratégia de defesa do tomateiro contra a mancha bacteriana.The efficacy of acibenzolar-S-methyl (ASM and Ecolife® and the activation of some defense responses against Xanthomonas vesicatoria were investigated in the current work.

    Full Text Available Las encefalitis son procesos inflamatorios de diverso origen, entre las cuales se incluyen las autoinmunes. La identificación de anticuerpos contra el receptor N-metil-D-aspartato permitió la caracterización clínico-inmunológica de una entidad susceptible a tratamiento inmunomodulador. Descripta originalmente en mujeres jóvenes, asociada a teratoma de ovario, es hoy una entidad reconocida en niños aun en ausencia de tumores detectables. El objetivo del trabajo, realizado a través de la revisión de historias clínicas, fue describir las características clínicas, evolutivas y los hallazgos en estudios complementarios de once niños con diagnóstico confirmado de esta entidad a través de la identificación de los anticuerpos específicos. Todos debutaron con síntomas psiquiátricos, en nueve de ellos asociando a convulsiones, y dos a movimientos extrapiramidales. En su evolución, todos presentaron compromiso del lenguaje, nueve, síntomas autonómicos graves, en uno con hipoventilación y requerimientos de ARM. La RM de cerebro fue anormal en tres. Ocho tuvieron EEG con asimetría del voltaje y/o amplitud, tres de ellos presentaron espigas. En el LCR seis tuvieron pleocitosis y tres de siete bandas oligoclonales positivas. Cinco, serologías IgM para micoplasma. El aumento de CPK en coincidencia con antipsicóticos ocurrió en cinco. Con el tratamiento inmunomodulador, cinco tuvieron recuperación total, tres, alteraciones conductuales/cognitivas y uno déficits severo. Un paciente resolvió su cuadro clínico sin tratamiento. En ninguno se detectó tumor asociado. Concluimos que frente a un niño con encefalopatía aguda y clínica compatible con esta entidad, una vez descartada causa infecciosa, se debe comenzar tratamiento inmunomodulador precozmente, evitar la utilización de fármacos antipsicóticos y realizar la búsqueda de posibles tumores ocultos.

    Full Text Available O objetivo deste trabalho foi estudar o efeito do tempo de envelhecimento natural do sistema catalítico versatato de neodímio/hidreto de di-isobutilalumínio/cloreto de t-butila sobre a polimerização de 2-metil, 1,3-butadieno (isopreno. Foram avaliadas a atividade catalítica e conversão, além da massa molar, distribuição de massa molar e microestrutura dos polímeros. Foi objetivo estudar também as características micro e macroestruturais do poli-1,4-cis-isopreno ao longo da polimerização. Os catalisadores envelhecidos apresentaram tempos mais curtos ao longo da polimerização e uma conversão mais alta em relação ao catalisador não envelhecido. Estes resultados em conjunto com a menor atividade catalítica nos catalisadores envelhecidos sugerem a provável desativação de alguns sítios ativos mais sensíveis. Não foi observada influência do envelhecimento do catalisador sobre a microestrutura do polímero. Houve também aumento da massa molar e estreitamento na polidispersão conforme o aumento da conversão.The goal of this work was to study the aging effects of the catalytic system neodymium versatate/diisobutylaluminium hydride/t-butyl chloride on 2-methyl, 1.3-butadiene (isoprene polymerization. The catalytic activity, conversion and polymer characteristics (molar mass, molar mass distribution and microstructure were evaluated. The macro and microstructural characteristics of poly-1.4-cis-isoprene along the polymerization were also studied. The aged catalysts have shorter times along the polymerization and a higher conversion than the non-aged catalyst. Together with the lower catalytic activity for aged catalysts, these results point to possible disabling of the most sensitive active sites. Aging of the catalyst did not affect the polymer microstructure. As the conversion progressed, the molar mass increased with a narrowing in the molecular weight distribution.

    Full Text Available A resistência induzida representa uma medida promissora no manejo de doenças como a murcha-de-Verticillium do cacaueiro (Theobroma cacao, visto que possibilita a exploração de cultivares com boas características agronômicas, porém apresentando suscetibilidade a doenças. Grande avanço nessa área ocorreu com a utilização do éster S-metil do ácido benzo-(1-2-3-tiadiazole-7-carbotióico (acibenzolar-S-metil, ASM. Contudo, a eficiência desse composto é função, principalmente, da época de aplicação e dosagem utilizada. O presente trabalho teve como objetivo identificar a melhor época de aplicação e dosagem do ASM na interação cacaueiro x Verticillium dahliae. O ASM foi pulverizado via foliar nas concentrações de 20 ou 60 g do ingrediente ativo (i. a./100 l de água, em plântulas de cacaueiro cv Theobahia, aos 15, sete ou três dias antes da inoculação do patógeno. Foram avaliadas as variáveis índice de doença, aos 30, 45 e 60 dias após a inoculação de V. dahliae, a área abaixo da curva de progresso da doença (AACPD, e o peso fresco e altura das plantas aos 60 dias após a referida inoculação. O fator época de aplicação apresentou influência predominante ao fator dosagem, sendo identificada a época referente a 15 dias antes da inoculação como melhor época de aplicação do ASM. Reduções de até 55,4% na severidade da doença e um acréscimo na ordem de 10,5% no peso fresco e 35,7% na altura das plantas foram observadas, quando da utilização da dosagem de 20 g do i.a./100 l de água, em comparação com as plantas somente inoculadas com o fungo, evidenciando a eficácia do ASM como indutor de resistência em plântulas de cacaueiro suscetíveis à murcha-de-Verticillium.Induced resistance represents a promissing strategy in the integrated management of Verticillium wilt of cocoa (Theobroma cacao, because it makes it possible to exploit susceptible cultivars with good agronomical characteristics

    An article in NASA Tech Briefs describing a vacuum bagging process for forming composite parts helped a small Oklahoma Company to improve its manufacturing process. President of Performance Extremes, Larry Ortega, and his partners make motorcycle parts from carbon/epoxy to reduce weight. Using vacuum bags, parts have a better surface and fewer voids inside. When heat used in the vacuum bag process caused deformation upon cooling, a solution found in another tech brief solved the problem. A metal plate inside the vacuum bag made for more even heat transfer. A third article described a simple procedure for repairing loose connector pins, which the company has also utilized.

    Full Text Available Methyl methracrylate (MMA is used widely for basic material in dental clinics. One of them is cold curing resin acrylic for orthodontics removable appliance. MMA is potentially to have the character to irritate and give an allergic reaction to oral mucous. Previous study showed that MMA have an effect on mitchondrial dehydrogenase repithelial cells by losing its hydrogen and tight on this enzyme. The influence of cold curing resins acrylic on DNA synthesis of oral mucous epithelial is not known until at present. The purpose of this in-vitro study is to examine the DNA synthesis of fibroblast cells BHK-21 induced MMA. The result of this study is to increase the DNA synthesis from the cell culture induced MMA monomer at an incubation time of 12 and 18 hours. Toxicity of MMA was proved to increase DNA synthesis because DNA has a more sensitive effect as a toxic material may cause a deviation of oral mucous.

    Full Text Available Caffeine catabolism and a xanthine oxidase involved in the alkaloid breakdown were studied in Pseudomonas putida L, a strain displaying high ability to grow on this substrate. Cells cultured with unlabelled caffeine and 14C labeled caffeine and xanthine showed that this alkaloid was broken-down via theobromine/paraxanthine -> 7-methylxanthine -> xanthine -> uric acid -> allantoin -> allantoic acid. Methyluric acids were formed from the oxidation of theobromine, paraxanthine and 7-methylxanthine, although no bacterial growth was observed on these compounds, indicating that this might be due to a wide substrate specificity of xanthine oxidase. This was confirmed by activity staining in PAGE where activity was observed with theophylline and 3-methylxanthine, which are not involved in the alkaloid breakdown. A single band of activity was detected without addition of NAD+, showing an oxidase form of the enzyme. The enzyme optimum temperature and pH were 30oC and 7.0, respectively. The determined Km was 169 µM, and the pI 3.1 - 4.0. The molecular weight determined by side by side comparison of activity staining of the enzyme in PAGE and PAGE of BSA was 192 kDa, which was coincident with the sum (198.4 kDa of three subunits (71, 65.6 and 61.8 kDa of the purified protein.O catabolismo de cafeína e a enzima xantina oxidase, envolvida na sua degradação, foram estudados em Pseudomonas putida L, uma linhagem com alta capacidade para utilizar este substrato como fonte de energia. Células crescidas na presença de cafeína e xantina marcadas com 14C, e cafeína não marcada, mostraram que este alcalóide foi degradado via teobromina/paraxantina -> 7-metilxantina -> xantina -> ácido úrico -> alantoína -> ácido alantóico. Ácidos metilúricos foram formados a partir de teobromina, paraxantina e 7-metilxantina, embora nenhum crescimento bacteriano ter sido observado quando estes compostos foram usados como substratos, indicando que a xantina oxidase

Assim sendo, foi conduzido um experimento na Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos - PR, no ano de 2004, com objetivo de avaliar a aplicação pré-colheita de quitosana e acibenzolar-S-metil (ASM sobre o comportamento pós-colheita de frutos de morangueiro da cultivar Aromas. O efeito da aplicação de quitosana (0,5; 1,0 e 2,0% e de uma dose de ASM (0,0025% foi verificado em relação à testemunha (água destilada e ao tratamento-controle com aplicação de fungicidas. A aplicação na pré-colheita de quitosana, nas três doses avaliadas, retardou a maturação dos frutos, manteve maior firmeza de polpa e acidez titulável e diminuiu a perda de massa. Esses tratamentos também diminuíram a produção de etileno, o teor de açúcares redutores e mantiveram mais elevado os teores de polifenóis totais. A aplicação de quitosana, nas três doses avaliadas, induziu maior resistência das plantas a patógenos, resultando na diminuição de podridão dos frutos em pós-colheita. No entanto, a concentração de 2% de quitosana causou dano aos frutos na pós-colheita, elevando a taxa respiratória e o teor de açúcares redutores. O ASM teve efeito na retenção da acidez titulável e na redução de podridões, similar ao tratamento com fungicidas. A aplicação de quitosana e ASM na pré-colheita não interferiu na qualidade organoléptica dos frutos em pós-colheita.The use of inductors of resistance in plants represents an alternative and a promising method to control fruit rots at post harvest.

O manejo da doença é principalmente preventivo e inclui o uso de porta-enxertos resistentes e a fumigação do solo. A proteção das mudas de macieiras antes do plantio com um isolado antagonista de Pantoea agglomerans foi recentemente proposto para reduzir a incidência da doença. Os objetivos desta pesquisa foram caracterizar o relacionamento entre o patógeno e a bactéria antagonista; a produção de metabólitos biológicamente ativos pelo isolado bacteriano e a sua ação sobre o patógeno; o efeito do pH, da temperatura e de carboxi-metil-celulose (CMC sobre o crescimento do antagonista e do patógeno, isolados ou não e no controle da doença. Os resultados demonstraram que o crescimento de P. agglomerans foi maior em pH 5,5 e 6,0 e nas temperaturas de 20 °C e 30 °C. O crescimento micelial de R. necatrix foi inibido em meio de cultura e previamente colonizado pelo antagonista e com CMC nas concentrações de 0,25 e 0,5 %. A proteção das macieiras da infecção por R. necatrix foi observada quando utilizadas as concentrações de 10(7; 10(8 e 10(9 cel/mL e nas diferentes concentrações de CMC. Maior desenvolvimento radicular das macieiras foi constatado em todas as concentrações de CMC quando usada a concentração de 10(9 cel/mL.

Após a validação analítica foi observado que o método CLAE apresentou melhores precisão intra e interensaio, porcentagem de recuperação e sensibilidade. Amostras de urina de trabalhadores expostos aos dois solventes em fábrica de tintas-látex foram analisadas pelos dois métodos validados e os resultados avaliados estatisticamente. Não se encontrou diferença significativa entre os valores de AH superiores a 1,0 g/g de creatinina, quando determinados pelos dois métodos cromatográficos. Esta similaridade não foi repetida quando os níveis de AH eram inferiores a 1,0 g/g de creatinina. Os valores de AMH nas amostras analisadas estavam, na maioria das vezes, abaixo do limite de deteção, razão pela qual não foi realizada a comparação estatística entre os mesmos.High performance liquid chromatography and capillary gas chromatography were compared for simultaneous measurement of hyppuric and methyl hyppuric acids in urine of workers co-exposed to toluene and xilene. Quantitative advantages offered by HPLC over capillary GC method are observed: better average recovery, wider dynamic interval in calibration curve and lower detection and quantification limits mainly when MHA measurement was performed. No significant difference was found between the values of HA higher than 1.0 g/g creatinine measured by the two chromatographic procedures. Regarding to MHA concentration the methods gave similar results and there was no significant difference between the values.

    International Nuclear Information System (INIS)

    The Controlled Parts Management (CPM) system is based on industry standard practices for managing inventory. CPM is designed to record the movement of any type of inventory in a defined region referred to as an Account or SubAccount. The system is used to track the receiving, processing, storing and transfer of inventory parts. CPM provides information on parts, quantity and the exact location of the inventory. CPM is a barcode-based-part tracking system currently used to track controlled parts that are used in the R and D and testing of weapons; this tracking helps maintain the part pedigree that is required for certification of a weapon or weapon test. CPM includes bar code data collection software programmed into portable bar code readers for automating physical inventory services and remote transaction capture. CPM interfaces to other Engineering systems and supports a 'material content' of a weapons test through the test Bill of Materials and assignment of a unique inventory part in CPM. Additional functionality includes the ability to group or join parts, logically or physically and temporary or permanent, to represent discrete parts, containers, subassemblies and assemblies, and groupings.

    Thiosemicarbazones have attracted great pharmacological interest because of their biological properties, such as cytotoxic activity against multiple strains of human tumors. The most studied compounds are pyridine-based because of their resemblance to pyridoxal metabolites that attach to co-enzyme B{sub 6}-dependant enzymes. This work aimed the characterization of the anti tumoral effect of N(4)-methyl-tolyl-2-acetylpyridine and 2-pyridinoformamide-derived thiosemicarbazones and the development of a radiopharmaceutical based on a thiosemicarbazone metal complex for positron emission tomography. In the first phase of this study were synthesized twenty-one thiosemicarbazones, derived from N(4)methyl-2 acetylpyridine and 2-pyridine formamide, as well as their metal complexes (Sn, Ga and Cu). Their cytotoxic potential were evaluated against brain and breast tumor cells in vitro. Our results showed all of them presented powerful cytotoxic and antiproliferative activities against glioblastoma multiform and breast adenocarcinoma at very low concentrations (nanomolar range). Morphological alterations characteristic of apoptosis, such as cell shrinkage, chromatin condensation were observed. Copper chloride was used as control and has presented IC50 at millimolar range suggesting that copper complexation with thiosemicarbazone significantly increases (more than 1 million) the anti tumoral effect of this metal. Due to the potent anti tumoral activity of N(4)-methyl-tolyl-2-acetylpyridine derived thiosemicarbazones and the excellent properties of {sup 64}Cu (T{sub 1/2} = 12.7 hours, {beta}{sup +}, {beta}{sup -}, and EC decay), at the second part for this work it was developed a new imaging agent (radiopharmaceutical) for tumor detection by positron emission tomography (PET).

  14. Concern for older parts

    International Nuclear Information System (INIS)

    For the last half decade, regulatory expectations of the procurement process for nuclear commercial-grade safety-related materials have increase. The changes have been driven by concern for fraudulent or misrepresented parts and the loss of original equipment manufacturers. The industry responded to these concerns by developing improved procurement programs that changed how parts were specified and received and provided for verification of attributes that were critical to the successful performance of safety functions(s). Like its counterparts, Duquesne Light Company (DLCo), Beaver Valley power station began applying these enhanced requirements to procurements initiated after January 1, 1990, in response to the Nuclear Management and Resources Council initiative on dedication. Procurements prior to this data were not subject to the new requirements

  19. Measurement of cylindrical parts

    Science.gov (United States)

    Knight, Paul Douglas, Jr.

    The form of cylindrical parts has been traditionally evaluated using stylus-based mechanical instruments. The Tropel Corporation has developed a grazing incidence interferometer (GII) for the measurement of cylindrical parts. The repeatability of this instrument due to various instrument uncertainties was measured. Differing instrument configurations that produce the same systematic error were determined to produce a zonal calibration method for determining systematic error over the full range of the instrument, given knowledge of the error in a single zone. The effect of the aperture stop on the response of the imaging system to axially sinusoidal artifacts was simulated. Diamond-turned axially sinusoidal artifacts, with amplitude of order1 um and spatial wavelength of order10 mm, were measured to test the axial response of the interferometer. The modulation transfer function of the instrument's imaging system, measured using a knife edge test, predicts the response observed with the sinusoidal artifacts. A diffraction analysis predicts that the measured axial form is modified by a second order envelope function with phase that varies with the relative position of the imaging system focal plane and part position. A compensation method is proposed for this effect. A comparison of roundness measurements by both a traditional stylus-based instrument and the GII was performed demonstrating that the roundness measurements of the two instruments are equivalent when the measurements are properly corrected for the differing effects of surface finish.

    Full Text Available Synthesis of ferrate and its application to azo dyes degradation have been investigated. The synthesis was carried out by reacting Fe(NO33 solution with NaOCl in alkaline condition. Oxidation reaction of azo dyes was carried out by adjusting the molar ratio of ferrate to azo dyes. When ferrate reacted with azo dyes, its absorbance was monitored using UV-Vis spectrophotometer at pH condition that had been optimized. Kinetics study for azo dyes degradation was carried out at the absorbance maximum of azo dyes, as a function of time. Ferrate can oxidize azo dyes, methyl oranye effectively in optimum pH of 9.6. With the molar ratio of ferrate/azo dyes 5/1, it showed that the percentages of methyl oranye degradation reached 100%. The azo dyes degradation followed first order of kinetics. Analysis using UV-Vis spectrofotometry suggests that the products of azo dyes degradation are nitrate, ammonia, and benzene. This results showed that ferrate is an alternative and green oxidizing agent which can be used for azo dyes degradation.

    Full Text Available This paper discusses experimental results on some parameters of palm methyl ester as insulating oil. Destillations are firstly made to obtained the composition of oil that provide the optimal compromise among measured parameters. Breakdown voltage, dissipation factor, dielectric constant, viscosity and oxidation stability were then tested on original, destilled, and destillation residual oils. The results showed that the dissipation factor and viscosity of destilled palm methyl ester comply with the standard spesification for natural ester to be used as insulating oil. Sadly, the breakdown voltage and oxidation stability of oils do not fulfill the standard. However, the lower breakdown voltage of oils seem to be tolerable as their value are still higher then that of mineral oil. Dielectric constant of oils which were higher then that of mineral oil is an advantage when the oils will be used in combination with solid insulation for more uniformly field reason.

  12. Invisible parts of attractors

    International Nuclear Information System (INIS)

    This paper deals with attractors of generic dynamical systems. We introduce the notion of ε-invisible set, which is an open set of the phase space in which almost all orbits spend on average a fraction of time no greater than ε. For extraordinarily small values of ε (say, smaller than 2−100), these are large neighbourhoods of some parts of the attractors in the phase space which an observer virtually never sees when following a generic orbit. For any n ≥ 100, we construct a set Qn in the space of skew products over a solenoid with the fibre a circle having the following properties. Any map from Qn is a structurally stable diffeomorphism; the Lipschitz constants of the map and its inverse are no greater than L (where L is a universal constant that does not depend on n, say L n has a 2−n-invisible part of its attractor, whose size is comparable to that of the whole attractor. The set Qn is a ball of radius O(n−2) in the space of skew products with the C1 metric. It consists of structurally stable skew products. Small perturbations of these skew products in the space of all diffeomorphisms still have attractors with the same properties. Thus for all such perturbations, a sizable portion of the attractor is almost never visited by generic orbits and is practically never seen by the observer

  13. Mapping sequences by parts

    2007-09-01

    Full Text Available Abstract Background: We present the N-map method, a pairwise and asymmetrical approach which allows us to compare sequences by taking into account evolutionary events that produce shuffled, reversed or repeated elements. Basically, the optimal N-map of a sequence s over a sequence t is the best way of partitioning the first sequence into N parts and placing them, possibly complementary reversed, over the second sequence in order to maximize the sum of their gapless alignment scores. Results: We introduce an algorithm computing an optimal N-map with time complexity O (|s| × |t| × N using O (|s| × |t| × N memory space. Among all the numbers of parts taken in a reasonable range, we select the value N for which the optimal N-map has the most significant score. To evaluate this significance, we study the empirical distributions of the scores of optimal N-maps and show that they can be approximated by normal distributions with a reasonable accuracy. We test the functionality of the approach over random sequences on which we apply artificial evolutionary events. Practical Application: The method is illustrated with four case studies of pairs of sequences involving non-standard evolutionary events.

  5. Identification based on facial parts

    2007-01-01

    Full Text Available Two opposing views dominate face identification literature, one suggesting that the face is processed as a whole and another suggesting analysis based on parts. Our research tried to establish which of these two is the dominant strategy and our results fell in the direction of analysis based on parts. The faces were covered with a mask and the participants were uncovering different parts, one at the time, in an attempt to identify a person. Already at the level of a single facial feature, such as mouth or eye and top of the nose, some observers were capable to establish the identity of a familiar face. Identification is exceptionally successful when a small assembly of facial parts is visible, such as eye, eyebrow and the top of the nose. Some facial parts are not very informative on their own but do enhance recognition when given as a part of such an assembly. Novel finding here is importance of the top of the nose for the face identification. Additionally observers have a preference toward the left side of the face. Typically subjects view the elements in the following order: left eye, left eyebrow, right eye, lips, region between the eyes, right eyebrow, region between the eyebrows, left check, right cheek. When observers are not in a position to see eyes, eyebrows or top of the nose, they go for lips first and then region between the eyebrows, region between the eyes, left check, right cheek and finally chin.

  6. Formation of parting in quartz

    Jørgen Kjøll, Hans; Eske Sørensen, Bjørn

    2014-05-01

    This paper presents hydrothermal quartz with macroscopic planar parting from the Mesoproterozoic Modum complex in southern Norway. Similar macroscopic parting in hydrothermal quartz with macroscopic planar structures has only been described from two localities in the world; Madagascar (Flörke et al., 1981) and Southern California (Murdoch et al., 1938). The study area consists of well foliated and banded sillimanite- garnet- amphibolite- mica gneiss that is cut at high angle by hydrothermal veins containing albite, chlinoclore, hornblende, hydroxyl apatite and quartz. The rim of the veins is generally made up of almost pure end-member euhedral albite. Then there is vugs with euhedral hornblende (10-25cm long) and euhedral hydroxyl apatite with size ranging from mm scale to several cm. Some places the quartz encloses apatite and hornblende. The quartz is anhedral, inequigranular with undulose extinction bordering sub grain rotation. It has large planar penetrative parting faces with pearly luster; however this is not consistent throughout the outcrop and some places the penetrative faces disappears and the quartz has a conchoidal fracture. The planar faces continue throughout the specimens with a few mm spacing. Thin sections oriented perpendicular to the most pronounced planar structure show lamellas that extinguishes at small angles (2 degrees) to each other. EBSD mapping of the planar faces shows two orientations {0-111} and {1-101}, corresponding to the r- and z-faces respectively, separated by irregular boundaries. The misorientation between these two crystallographic orientations on the parting is a 60 degree rotation on [0 0 1] in correspondence to the dauphiné twin law. Investigations conducted on thin sections cut orthogonal to the parting shows that the parting cuts and offsets the dauphiné twins, indicating a late genesis of the parting. However some internal stress induced movement of the twins are visible. SEM-CL documents three generations of quartz

  9. Part Fixturing For Diamond Machining

    Science.gov (United States)

    Chaloux, Leonard E.

    1984-12-01

    Successful production of diamond turned components can be extremely dependent on the fixturing used to support the workpiece during the machining operation. Typical fixturing methods include vacuum chucking, air chucking and mechanical clamping. Depending on the type of part to be machined, suggested fixturing methods can vary widely. For example, a part requiring a flycut surface is not subject to the centrifugal forces and balance requirements of a part that must be turned about an axis of rotation. Therefore, in many cases the fixturing required for flycutting may be much simpler than that required for turning. In all cases, there are general guidelines that should be followed to determine the best method of fixturing.

  11. Focusing the partly polarized light

    Borovytsky, Volodymyr

    2015-11-01

    The paper presents the mathematical technique for calculation of three dimensional intensity distribution near a focal point of an optical system in case of partly polarized light. The proposed technique considers a high aperture optical system that focuses a partly polarized parallel beam. The principal idea is based on Huygens-Fresnel principle: a spherical wave at an exit pupil of an optical system is considered as a numerous set of secondary light point sources. Each source emits a partly polarized spherical wave. The polarization orientation of each wave can be calculated using angular pupil coordinates. Modulation of amplitude, phase or polarization can be introduced depending on these pupil coordinates. The total intensity is defined as superposition of complex wave amplitudes taking into account polarization orientation, degree of polarization and orientation of detector aperture. The paper presents the intensity distributions calculated for beams with various types and degrees of polarization.

  2. Cleaning of parts for new manufacturing and parts rebuilding

    Science.gov (United States)

    Doherty, Jeff

    1994-06-01

    Parts cleaning is the largest single expense, and the most time consuming activity, in rebuilding and new manufacturing. On average, 25% to 40% of the total labor and overhead burden is spent on cleaning. EPA and OSHA pressures add to the burden by making some methods and chemicals obsolete. Some of the processes and chemicals in current use will be curtailed and or outlawed in the future. How can a shops and industries make long term decisions or capital investments in cleaning and process improvements when the government keeps changing its rules? At the MART Corporation in Saint Louis, Missouri, we manufacture a line of cabinet-style batch cleaning machines known as Power Washers. Twenty years ago MART invented and patented the Power Washer process, a cleaning method that recycles wash solution and blasts contaminates as they are washed off the more heavily contaminated parts. Since the initial invention MART has continued to R&D the washing process and develop ancillary systems that comply with EPA and OSHA regulations. For applications involving new industrial parts or items requiring specification cleaned surfaces. MART provides filtration and solution conditioning systems, part drying operations, and triple rinsing. Units are available in stainless steel or higher alloys. We are not alone in the washer manufacturing business. You have many choices of cleaning solutions (no pun intended) which will perform in your operations and yield good results. As a manufacturer, we are interested in your success with our equipment. We have all heard the horror stories of companies having selected inappropriate cleaning systems and or processes which then brought the company to its knees, production wise. Assembly, appearance, warranty, and performance shortcomings of finished products can often be directly related to the cleaning process and its shortcomings.

  3. CERN: Real and imaginary parts

    International Nuclear Information System (INIS)

    Full text: Elastic scattering (where particles bounce off each other) has implications which go far beyond the deceptive simplicity and inconsequence of this process. Several years ago, an elastic scattering result by the UA4 experiment at CERN's proton-antiproton collider (January 1988, page 32) set the high energy world talking. In quantum mechanics, the forward elastic scattering amplitude is a complex number whose real and imaginary parts can be related. The powerful 'optical theorem' relates the total reaction rate (cross-section) to the imaginary part of the forward scattering amplitude, while the ratio of the real and imaginary parts gives an indication of where the total reaction rate is going at higher energies, independent of what the actual mechanisms are. Thus, for example, elastic scattering measurements at CERN's Intersecting Storage Rings pointed the way to the behaviour eventually seen at the proton-antiproton collider. In the 1985 run, UA4 found the ratio (rho) between the real and the imaginary parts to be 0.24, about twice the theoretical prediction. At face value, this suggested that the total reaction rate would increase dramatically at higher collision energies. With such a prediction at stake, confirmation with a more precise measurement was necessary and the UA4/2 experiment (Genoa/ Palaiseau/Prague/Rome/Valencia collaboration) was launched. The real part of the scattering amplitude is obtained via measurements of elastic scattering in a four momentum transfer domain where strong and electromagnetic interactions are comparable. This corresponds to scattering angles of 100 microradians, with the detectors inside ''Roman pots'' close to the circulating beams, and using special beam optics. The new experiment took place in a five-week run late in 1991. With the Roman pots within 2mm of the beams, about a million elastic events were recorded. Several months later, a special dedicated run fixed the SPS

    2014-06-01

    Full Text Available Fatigue design of automotive axle parts is of prior concern because of these are high safety parts and they are expected to drive the overall vehicle mass reduction. In this framework, the stamping process is widely used to form axle parts, before assembling them by welding. Consequently, the mechanical and physical characteristics of the blank sheet are modified, having a strong influence on the fatigue behavior. In this paper, we address the consequences of the stamped process on the fatigue design and how they may be effectively taken into account in the automotive industry. Actually, the coupling between the stamping process and the fatigue design is under development at PSA Peugeot Citroën Company since several years. Such an analysis deals with some major topics: thickness variation, plastic hardening and deformation, and residual stress. All of these ingredients result in fatigue criteria evolutions: it is important to stress that the stamping process can have advantageous or disadvantageous consequences on the fatigue design. This is here highlighted on some examples, dealing with front and rear axles.

  11. Can statins improve outcome in colorectal surgery?: Part I

    Full Text Available Statins are recommended for people who have high serum cholesterol, and this role of statins has been well documented. However, some activities of statins, independent of their lipid-lowering effect, in conditions such as systemic inflammatory response syndrome, nephropathy, and other anti-inflammatory activities that reduce proinflammatory cytokines, are called "pleiotropic" effects of statins. For this reason, many candidates for surgical treatment are users of statins. As a result, benefits are observed in these patients, such as minimized postoperative complications, especially in cardiac or coronary surgery. This study was designed with the purpose of determining the current status of the use of statins as an adjuvant in the prevention of postoperative complications in colorectal surgery. Ongoing studies and future researches will help clarify the potential impact of statins on the prophylaxis of postoperative complications.As estatinas são drogas com o poder de inibir a hidroxi-metil-glutaril coenzima A redutase (HMG-CoA redutase, enzima que age na ativação da cadeia metabólica do colesterol. Portanto, sua principal ação, entre outros efeitos, é diminuir a concentração sérica total desse lipídeo. Por essa razão, muitas pessoas candidatas ao tratamento cirúrgico são pacientes usuários das estatinas. Seus outros efeitos, independente de sua capacidade para baixar os lipídeos circulantes, são denominados "efeitos pleiotrópicos" e estão, principalmente, relacionados à ação de bloqueio das atividades pró-inflamatórias, sobretudo minimizando, nos cardiopatas ou coronariopatas submetidos às operações cardíacas ou coronarianas, a prevalência da síndrome da reação inflamatória sistêmica, inclusive quando desencadeada por infecção. Estudos recentes têm sido elaborados para maiores conhecimentos dos mecanismos de ação das estatinas, especialmente em pacientes cardiopatas submetidos a tratamentos cirúrgicos n

    Full Text Available The aim of this research was to know effect of methyl jasmonate addition in any concentration on the callus growth and alkaloid reserpine production from in vitro culture of pule pandak [Rauvolfia serpentina (L. Bentham ex. Kurz.]. The research frame based on the advantage of pule pandak as medicine plants sources. The addition of methyl jasmonate on the callus medium would inhibit the callus growth. It also has effects for the synthesis stricthosidine synthase. This enzyme had essential role on the reserpine biosynthesis. The research was conducted of two steps. First, initiation step to induct the callus formation. Second, treatment step to induct reserpine production. The research was done by designing a factor random completed, that is methyl jasmonate concentration. Methyl jasmonate concentration which is 0 μM, 10 μM, 20 μM, 40 μM, 80 μM, and 100 μM. The result data was qualitative form, that was callus morphology and quantitative form, fresh weight and dried weight, and reserpine content. The analysis of data used the ANOVA and DMRT 5%. The result of this research indicated that increasing of methyl jasmonate addition reduced the callus growth. The more methyl jasmonate concentration (10, 20, 40, 80 μM was added, the higher reserpine was produced. Methyl jasmonate concentration in 80 μM produced the highest reserpine content that is 0.75 mg/g.

    Full Text Available The increased use of small gas turbines and turbochargers in different technical fields has led to the development of highly-loaded centrifugal compressors with extremely thin blades. Due to the high rotational speed and the corresponding centrifugal load, the shape of the impeller hub must also be optimized. This has led to a reduction of the thickness of the impeller disc in the outlet region. The thin parts of the impeller are very sensitive and may be damaged by the excitation of dangerous blade vibrations.

    2016-04-27

    The previous article in this series of 11, Facilitation of learning: part 1, reviewed learning theories and how they relate to clinical practice. Developing an understanding of these theories is essential for mentors and practice teachers to enable them to deliver evidence-based learning support. This is important given that effective learning support is dependent on an educator who possesses knowledge of their specialist area as well as the relevent tools and methods to support learning. The second domain of the Nursing and Midwifery Council's Standards to Support Learning and Assessment in Practice relates to the facilitation of learning. To fulfil this domain, mentors and practice teachers are required to demonstrate their ability to recognise the needs of learners and provide appropriate support to meet those needs. This article expands on some of the discussions from part 1 of this article and considers these from a practical perspective, in addition to introducing some of the tools that can be used to support learning.

Due to serious design issues, spiraling high costs and years in delays, alternatives are analyzed here, depicted and proposed, mainly from the propulsion-design point of view. These include fleets of low-cost, stealth, jet-steered-drones mixed with non-stealthy, low-cost, ready-to-be-delivered, U.S. or European or Russian fighter aircraft. Can a few F-35s win against large fleets of stealth agile drones? To understand the dangers and critical issues involved, the author's own, past classified information is partly disclosed, while resorting to images in Figs. 2(a) and 2(b) taken from his book [2] and from Wikipedia, the "Free Encyclopedia", in all other images.

    Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF): neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis (SCH). NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1. PMID:26083891

    2013-03-15

    An outline is given of the social dilemmas associated with agriculture and horticulture in the Netherlands. Ongoing innovation and accelerated sustainable development are essential to resolve these dilemmas. Given the importance of the Dutch agriculture and horticulture sector, there is every reason for the central government to play its part and help remove the obstacles to the continuing sustainable development of the sector. The Council recommends that the central government continues developing the Council's vision for agriculture and horticulture with the parties concerned, allows scope for the development of different agricultural business models, applies knowledge and innovation as drivers of continuing sustainable development, amends laws and regulations as necessary, and facilitates a permanent dialogue between the sector and society. The advisory report also sets out the Council's vision concerning the political and public debate on agriculture and horticulture. This debate is most clearly characterised by major and seemingly insurmountable differences of opinion. The Council hopes that its report will induce a shift in thinking about Dutch agriculture among politicians and society at large, so that the transitions considered necessary by the Council can be implemented more rapidly.

    Many high-reliability systems, including space systems, use selected commercial parts (including Plastic Encapsulated Microelectronics or PEMs) for unique functionality, small size, low weight, high mechanical shock resistance, and other factors. Predominantly this usage is subjected to certain 100% tests (typically called screens) and certain destructive tests usually (but not always) performed on the flight lot (typically called qualification tests). Frequently used approaches include those documented in EEE-INST-002 and JPL DocID62212 (which are sometimes modified by the particular aerospace space systems manufacturer). In this study, approaches from these documents and several space systems manufacturers are compared to approaches from a launch systems manufacturer (SpaceX), an implantable medical electronics manufacturer (Medtronics), and a high-reliability transport system process (automotive systems). In the conclusions section, these processes are outlined for all of these cases and presented in tabular form. Then some simple comparisons are made. In this introduction section, the PEM technology qualification process is described, as documented in EEE-INST-002 (written by the Goddard Space Flight Center, GSFC), as well as the somewhat modified approach employed at the Jet Propulsion Laboratory (JPL). Approaches used at several major NASA contractors are also described

  6. Drilling miniature holes, Part III

    Energy Technology Data Exchange (ETDEWEB)

    Gillespie, L.K.

    1978-07-01

    Miniature components for precision electromechanical mechanisms such as switches, timers, and actuators typically require a number of small holes. Because of the precision required, the workpiece materials, and the geometry of the parts, most of these holes must be produced by conventional drilling techniques. The use of such techniques is tedious and often requires considerable trial and error to prevent drill breakage, minimize hole mislocation and variations in hole diameter. This study of eight commercial drill designs revealed that printed circuit board drills produced better locational and size repeatability than did other drills when centerdrilling was not used. Boring holes 1 mm in dia, or less, as a general rule did not improve hole location in brass or stainless steel. Hole locations of patterns of 0.66-mm holes can be maintained within 25.4-..mu..m diametral positional tolerance if setup misalignments can be eliminated. Size tolerances of +- 3.8 ..mu..m can be maintained under some conditions when drilling flat plates. While these levels of precision are possible with existing off-the-shelf drills, they may not be practical in many cases.

  8. [First part: the intestinal microbiota].

    Science.gov (United States)

    Capurso, Lucio

    2016-06-01

    The human gastrointestinal tract contains a large number of commensal (non pathogenic) and pathogenic microbial species that have co-evolved with the human genome and differ in composition and function based on their location, as well as age, sex, race/ethnicity, and diet of their host and we can in fact consider the human body as a mix of human and bacterial cells. It is now evident that the large intestine is much more than an organ for waste material and absorption of water, salts and drugs, and indeed has a very important impact on human health, for a major part related to the specific composition of the complex microbial community in the colon. In man, the large gut receives material from the ileum which has already been digested and the contents are then mixed and retained for 6-12 hours in the caecum and right colon. Thus, the large intestine is an open system, with nutrients flowing in the caecum, and bacteria, their metabolic products, and undigested foodstuffs being excreted as faeces. The anaerobic brakdown of carbohydrate and protein by bacteria is known conventionally as fermentation. In man the major end products are the short-chain fatty acids (SCFA) acetate, propionate, butirate, the gases H2 and CO2, ammonia, amines, phenols and energy, which the bacteria use for growth and the maintenance of cellular function. The microbiota is also an important factor in the development of the immune response. The interaction between the gastrointestinal tract and resident microbiota is well balanced in healthy individuals, but its breakdown can lead to intestinal and extraintestinal disease.

  15. Changing nature of equipment and parts qualification

    International Nuclear Information System (INIS)

    Ideally, the original supplier of a piece of nuclear safety-related equipment has performed a qualification program and will continue to support that equipment throughout the lifetime of the nuclear power plants in which in equipment is installed. The supplier's nuclear quality assurance program will be maintained and he will continue to offer all necessary replacement parts. These parts will be identical to the original parts, certified to the original purchase order requirements, and the parts will be offered at competitive prices. Due to the changing nature of the nuclear plant equipment market, however, one or more of those ideal features are frequently unavailable when safety-related replacement equipment or parts are required. Thus, the process of equipment and parts qualification has had to adjust in order to ensure obtaining qualified replacements when needed. This paper presents some new directions taken in the qualification of replacement equipment and parts to meet changes in the marketplace

  2. Metallic parts fabrication using the SIS process

    Science.gov (United States)

    Mojdeh, Mehdi

    Since early 1980s, quite a few techniques of Rapid Prototyping (RP), also known as Layered Manufacturing, have been developed. By building three-dimensional parts in a layer-by-layer additive manner, these techniques allow freeform fabrication of parts of complex geometry. Despite recent advances in fabrication of polymer parts, most of the existing rapid prototyping processes are still not capable of fabrication of accurate metallic parts with acceptable mechanical properties. Insufficient dimensional accuracy, limited number of materials, proper mechanical properties, required post machining and lack of repeatability between builds have greatly limited the market penetration of these techniques. This dissertation presents an innovative layered manufacturing technique for fabrication of dense metallic parts called Selective Inhibition Sintering (SIS), developed at the University of Southern California. The SIS-Metal technology adapts RP capabilities and extends them to the field of fabrication of metallic parts for a variety of applications such as tooling and low volume production. Using this process, a metallic part, with varying 3 dimensional geometries, can be automatically constructed from a wide range of materials. SIS-Metal is the only RP process which is suitable for fabrication of dense, complex shaped, accurate objects using a variety of materials. In the SIS-Metal process a metallic part is built layer by layer by deposition for each layer of an inhibitor material which defines the corresponding layer boundary and then filling the voids of the created geometry with metal powder; and compacting the layer formed to reach a high powder density. The resulting green part is then sintered in a furnace to yield the final functional part. In this research different inhibition techniques were explored and a series of single and multi layer parts was fabricated using the most promising inhibition technique, namely, macro-mechanical inhibition.

  3. An inertial sensor for parts inspection

    OpenAIRE

    Tam, SM; Cheung, KC

    1995-01-01

    This paper describes the development of a sensor which performs parts inspection by measuring the inertial properties of the part. The sensor comprises a measuring platform supported on a column which is fixed to a rigid base. The part under inspection is attached to the platform to form a single body. By measuring the static deflections of the column and the natural frequency of vibration of the system, it is possible to determine the spatial location of the centre of mass of the part.

  4. Rotor instability due to loose rotating part

    Muszynska, A.

    1985-01-01

    Loosening of a rotating part from its fixed position on the shaft or a part of the stator which comes loose and begins to turn with the rotor very frequently represents machinery malfunction. The loose part becomes involved in rotative motion mostly due to dry or fluid friction, and thus its motion is very erratic. The loose part can also move axially along the shaft. Detachment of the rotating part causes changes in the rotor balance state. Most often this results in higher unbalance. During steady-state operation the effect of a loose rotating part can manifest itself through heat vibration. It can be diagnosed by observing periodic changes of amplitude and phase of the synchronous response. During start-up (or shutdown) a loose rotating part carrying some amount of unbalance may manifest its dynamic action in the form of subsynchronous vibrations, very similar to those of other instabilities. The objective of this demonstration is to observe the effect of a loose rotating part (fixed, however, in the axial direction) under both steady-state (rotor constant speed) and transient (rotor start-up or shutdown) operation. The dynamic response depends very much on the amount of damping in the system: lubrication of the loose part/shaft surfaces and addition/elimination of aerodynamic drag blades, mounted on the loose disk, significantly change the rotor response.

  5. Opportunistic replacement of fusion power system parts

    International Nuclear Information System (INIS)

    This paper describes a maintenance problem in a fusion power plant. The problem is to specify which life limited parts should be replaced when there is an opportunity. The objective is to minimize the cost rate of replacement parts and of maintenance actions while satisfying a power plant availability constraint. The maintenance policy is to look ahead and replace all parts that will reach their life limits within a time called a screen. Longer screens yield greater system availabilities because more parts are replaced prior to their life limits

    Cole, Reysen, and Kelley [2013. Part-set cuing facilitation for spatial information. Journal of Experimental Psychology: Learning, Memory, & Cognition, 39, 1615-1620] reported robust part-set cuing facilitation for spatial information using snap circuits (a colour-coded electronics kit designed for children to create rudimentary circuit boards). In contrast, Drinkwater, Dagnall, and Parker [2006. Effects of part-set cuing on experienced and novice chess players' reconstruction of a typical chess midgame position. Perceptual and Motor Skills, 102(3), 645-653] and Watkins, Schwartz, and Lane [1984. Does part-set cuing test for memory organization? Evidence from reconstructions of chess positions. Canadian Journal of Psychology/Revue Canadienne de Psychologie, 38(3), 498-503] showed no influence of part-set cuing for spatial information when using chess boards. One key difference between the two procedures was that the snap circuit stimuli were explicitly connected to one another, whereas chess pieces were not. Two experiments examined the effects of connection type (connected vs. unconnected) and cue type (cued vs. uncued) on memory for spatial information. Using chess boards (Experiment 1) and snap circuits (Experiment 2), part-set cuing facilitation only occurred when the stimuli were explicitly connected; there was no influence of cuing with unconnected stimuli. These results are potentially consistent with the retrieval strategy disruption hypothesis, as well as the two- and three-mechanism accounts of part-set cuing. PMID:26252760

  16. Recurring part arrangements in shape collections

    KAUST Repository

    Zheng, Youyi

    2014-05-01

    Extracting semantically related parts across models remains challenging, especially without supervision. The common approach is to co-analyze a model collection, while assuming the existence of descriptive geometric features that can directly identify related parts. In the presence of large shape variations, common geometric features, however, are no longer sufficiently descriptive. In this paper, we explore an indirect top-down approach, where instead of part geometry, part arrangements extracted from each model are compared. The key observation is that while a direct comparison of part geometry can be ambiguous, part arrangements, being higher level structures, remain consistent, and hence can be used to discover latent commonalities among semantically related shapes. We show that our indirect analysis leads to the detection of recurring arrangements of parts, which are otherwise difficult to discover in a direct unsupervised setting. We evaluate our algorithm on ground truth datasets and report advantages over geometric similarity-based bottom-up co-segmentation algorithms. © 2014 The Author(s) Computer Graphics Forum © 2014 The Eurographics Association and John Wiley & Sons Ltd.

    Detailed manufacturing information about the parts can help designers produce better designs. Detailed manufacturing information is conveyed to the designer through micro-circles within the concurrent design process for machined parts, focusing on instantaneous product design and process planning. The process has three key elements: a hierarchical architecture design of the concurrent process planning system, modeling and reengineering of the concurrent process planning, and modeling of information. The approach is successfully implemented and applied for concurrent design and process planning of some complicated parts.

  18. Smart variations: Functional substructures for part compatibility

    KAUST Repository

    Zheng, Youyi

    2013-05-01

    As collections of 3D models continue to grow, reusing model parts allows generation of novel model variations. Naïvely swapping parts across models, however, leads to implausible results, especially when mixing parts across different model families. Hence, the user has to manually ensure that the final model remains functionally valid. We claim that certain symmetric functional arrangements (sFarr-s), which are special arrangements among symmetrically related substructures, bear close relation to object functions. Hence, we propose a purely geometric approach based on such substructures to match, replace, and position triplets of parts to create non-trivial, yet functionally plausible, model variations. We demonstrate that starting even from a small set of models such a simple geometric approach can produce a diverse set of non-trivial and plausible model variations. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and Blackwell Publishing Ltd.

    This is Part 2 of a transcription of Bentham's manuscript essay on "Paederasty" (1785), Part 1 of which appeared in Vol. 3, No. 4. In Part 1 Bentham argued for the decriminalization of sodomy and opposed the theories of Montesquieu and Voltaire as to its social dangers. In Part 2 Bentham speculates on its causes and alleges that the real reason such behavior is so severely punished is an irrational "antipathy" to pleasure generally and to sexual pleasure in particular. He discusses the danger of blackmail and false accusations and the punishment of lesbian acts, bestiality, and masturbation. Some miscellaneous related notes by Bentham are appended: these deal with religious fears based on the destruction of Sodom, the threat to population, the harshness of English naval law, and other topics.

    2007-01-01

    Surface classification, 3D parting line, parting surface generation and demoldability analysis which is helpful to select optimal parting direction and optimal parting line are involved in automatic cavity design based on the ray-testing model. A new ray-testing approach is presented to classify the part surfaces to core/cavity surfaces and undercut surfaces by automatic identifying the visibility of surfaces. A simple, direct and efficient algorithm to identify surface visibility is developed. The algorithm is robust and adapted to rather complicated geometry, so it is valuable in computer-aided mold design systems. To validate the efficiency of the approach, an experimental program is implemented. Case studies show that the approach is practical and valuable in automatic parting line and parting surface generation.

  1. PART BUILDING ORIENTATION OPTIMIZATION METHOD IN STEREOLITHOGRAPHY

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Aiming at the part quality and building time problems in stereolithography (SL) caused by unreasonable building orientation, a part building orientation decision method in SL rapid prototyping (RP) is carried out. Bringing into full consideration of the deformation, stair-stepping effect, overcure effect and building time related to the part fabrication orientation, and using evaluation function method, a multi-objective optimization model for the building orientation is defined. According to the difference in the angles between normal vectors of triangular facets in standard triangulation language (STL) model and z axis, the expressions of deformation area, stair-stepping area, overcure area are established. According to the characteristics in SL process, part building time is divided into four sections, that is, hatching scanning time, outline scanning time, support building time and layer waiting time. Expressions of each building time section are given. Considering the features of this optimization model, genetic algorithm (GA) is used to derive the optimization objective, related software is developed and optimization results are tested through experiments. Application shows that this method can effectively solve the quality and efficiency troubles caused by unreasonable part building orientation, an automatic orientation-determining program is developed and verified through test.

  2. Prediction of Part Distortion in Die Casting

    Energy Technology Data Exchange (ETDEWEB)

    R. Allen Miller

    2005-03-30

    The die casting process is one of the net shape manufacturing techniques and is widely used to produce high production castings with tight tolerances for many industries. An understanding of the stress distribution and the deformation pattern of parts produced by die casting will result in less deviation from the part design specification, a better die design and eventually more productivity and cost savings. This report presents methods that can be used to simulate the die casting process in order to predict the deformation and stresses in the produced part and assesses the degree to which distortion modeling is practical for die casting at the current time. A coupled thermal-mechanical finite elements model was used to simulate the die casting process. The simulation models the effect of thermal and mechanical interaction between the casting and the die. It also includes the temperature dependant material properties of the casting. Based on a designed experiment, a sensitivity analysis was conducted on the model to investigate the effect of key factors. These factors include the casting material model, material properties and thermal interaction between casting and dies. To verify the casting distortion predictions, it was compared against the measured dimensions of produced parts. The comparison included dimensions along and across the parting plane and the flatness of one surface.

  3. Manufacture of plastic parts by radiation molding

    International Nuclear Information System (INIS)

    Thin plastic parts which can have precise tolerances and can be of complex shape are prepared by casting a viscous radiation-curable composition onto a support, such as a moving web of polymeric material, in the shape of the desired part and then irradiating, for example with ultraviolet radiation or high energy electrons, to cause curing of the composition to a solid plastic. The radiation-curable composition is formulated with viscosity and flow characteristics it to be cast in the exact shape of the part desired yet retain this shape during curing while supported only by the surface on which it has been cast. Plastic parts made by this method can be formed entirely of the radiation-curable composition by casting onto a web having a release surface from which the part can be stripped subsequent to curing or can be formed partially from a web material and partially from the radiation-curable composition by casting onto a web to which the composition will bond and subsequently cutting the web into discrete portions which include the cured composition

    2010-10-01

    This chapter presents a machine vision system for detecting surface imperfections on micro parts. It is part of a quality control concept for micro production. Because of increasing product miniaturization, the mechanical manufacturing of micro components is becoming more and more important. The combination of high manufacturing rates and low tolerances in manufacturing processes enables the economical production of micro components. Due to the small component sizes and the difficulties associated with the handling process, the manual visual inspection retires as testing procedure. A customized surface inspection technology with an efficient image processing and classification system is needed. The objective of our concept is to identify surface imperfections such as raisings, laps and bulges on micro parts. The implementation of the system is explained by reference to a micro deep-drawn component, which is manufactured within the German Collaborative Research Center (CRC) 747.

    Successful pregnancy requires a state of immune homeostasis. Maternal tolerance of the genetically distinct fetoplacental unit is in part mediated by maternal and fetal pro- and anti-inflammatory cytokines; these cytokines have also been implicated in different pregnancy-related pathologic states. This two-part series seeks to provide anesthesiologists with an overview on selected perinatal cytokines in an effort to identify opportunities for research and improvements in clinical care. In part one, we review basic and pregnancy-related elements of the immune system, with an emphasis on the role of cytokines. From this foundation, we offer a perspective of a unique phenomenon witnessed within obstetric anesthesia - maternal temperature elevation associated with labor epidural analgesia. PMID:26970932

    2012-02-01

    Full Text Available Clustering algorithms are used in many Natural Language Processing (NLP tasks. They have proven to be popular and effective tools to use to discover groups of similar linguistic items. In this exploratory paper, we propose a new clustering algorithm to automatically cluster together similar sentences based on the sentences’ part-of-speech syntax. The algorithm generates and merges together the clusters using a syntactic similarity metric based on a hierarchical organization of the parts-of-speech. We demonstrate the features of this algorithm by implementing it in a question type classification system, in order to determine the positive or negative impact of different changes to the algorithm.

  11. Education, Employment and Economic Performance: Part II

    Directory of Open Access Journals (Sweden)

    Pankhurst, Kenneth V.

    2001-01-01

    Full Text Available Part I (published in Vol. 9 1997 reviewed the weaknesses of public education and training policies and programmes for dealing with problems of the economy and the labour market. This Part discusses some of the findings of research about how workers learn. Learning-by-doing during production links education, employment and production methods and is one source of economic progress. The challenge to education and labour market policies is to harness the ability of human beings to think independently, to recognize and resolve problems, and not to instruct workers in specific ways of doing their jobs.

    Moss, Chantrice; Chakrabarti, Suman; Scott, David W.

    2013-01-01

    A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using direct part marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, Low Earth Orbit), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (label printing, data plates, and direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including inhouse vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

    Science.gov (United States)

    Kevilj, R; Mehulic, K; Dundjer, A

    2007-01-01

    Correct functioning of the entire stomatognathic system is achieved by a compatible relationship of all its parts. Four determinants, by their mutual harmonious activity, dictate the function of the entire system: the teeth, periodontium with supporting structure, muscles, temporomandibular joint (TMJ) and CNS. In such a complex system a disorder of any integrative part causes disturbances also in other parts of the system. Changed functions can arise through organic disorder, and also iatrogenically by inadequate conservative, prosthetic, surgical or orthodontic therapy. For this reason it is often difficult to recognise the primary cause. The first responses of the system to the disorder are adaptive mechanisms which occur within one or more integrative parts, and depending on their intensity and duration symptoms grow more prominent. Tissue response can be ortho- or parafunctional. Attempts are made to exclude psychoemotional influences and the obstacle eliminated by either abrasion, clenching or grinding of the teeth. If the obstacle is not eliminated by abrasion, the cause of such functional disorder becomes the trigger for parafunctional activity. From a review of the relevant literature it can be concluded that parafunctional activity is caused by changed occlusion, with determined psychological habits of the patient and specific tissue response of the stomatognathic system. Therefore, therapy of these disorders is made more difficult and includes a multidisciplinary approach. PMID:17912197

    2015-08-17

    Since the invention of modern Additive Manufacturing (AM) processes engineers and designers have worked hard to capitalize on the unique building capabilities that AM allows. By being able to customize the interior fill of parts it is now possible to design components with a controlled density and customized internal structure. The creation of new polymers and polymer composites allow for even greater control over the mechanical properties of AM parts. One of the key reasons to explore AM, is to bring about a new paradigm in part design, where materials can be strategically optimized in a way that conventional subtractive methods cannot achieve. The two processes investigated in my research were the Fused Deposition Modeling (FDM) process and the Direct Ink Write (DIW) process. The objectives of the research were to determine the impact of in-fill density and morphology on the mechanical properties of FDM parts, and to determine if DIW printed samples could be produced where the filament diameter was varied while the overall density remained constant.

  20. Laser welding of micro plastic parts

    Science.gov (United States)

    Haberstroh, E.; Hoffmann, W.-M.

    2007-02-01

    Most welding processes for plastics do not meet the demands of micro technology and thus cannot be applied in this innovative industrial sector. One of the few techniques which are applicable in this sector is the laser transmission welding, which has distinctive advantages like low mechanical and thermal load of the joining parts. This makes the laser particularly suitable for the welding of micro plastics parts. Thereby, contour welding is a process variant of laser transmission welding enabling the welding of complex and even three-dimensional weld contours. But so far it has not yet been applied for welding plastics parts of micro scale in the industrial practice. Recent research at the Institute of Plastics Processing (IKV) at the RWTH Aachen University shows the feasibility of this process to weld small and complex micro parts. Good mechanical properties can be achieved. However, it is necessary to apply measures to reduce the formation of flash. Moreover, it can be shown that there is a strong influence of some material parameters on the laser welding process so that some plastics are more suitable than others for the contour welding in micro technology.

  2. Cryogenic Quenching Process for Electronic Part Screening

    Science.gov (United States)

    Sheldon, Douglas J.; Cressler, John

    2011-01-01

    The use of electronic parts at cryogenic temperatures (less than 100 C) for extreme environments is not well controlled or developed from a product quality and reliability point of view. This is in contrast to the very rigorous and well-documented procedures to qualify electronic parts for mission use in the 55 to 125 C temperature range. A similarly rigorous methodology for screening and evaluating electronic parts needs to be developed so that mission planners can expect the same level of high reliability performance for parts operated at cryogenic temperatures. A formal methodology for screening and qualifying electronic parts at cryogenic temperatures has been proposed. The methodology focuses on the base physics of failure of the devices at cryogenic temperatures. All electronic part reliability is based on the bathtub curve, high amounts of initial failures (infant mortals), a long period of normal use (random failures), and then an increasing number of failures (end of life). Unique to this is the development of custom screening procedures to eliminate early failures at cold temperatures. The ability to screen out defects will specifically impact reliability at cold temperatures. Cryogenic reliability is limited by electron trap creation in the oxide and defect sites at conductor interfaces. Non-uniform conduction processes due to process marginalities will be magnified at cryogenic temperatures. Carrier mobilities change by orders of magnitude at cryogenic temperatures, significantly enhancing the effects of electric field. Marginal contacts, impurities in oxides, and defects in conductor/conductor interfaces can all be magnified at low temperatures. The novelty is the use of an ultra-low temperature, short-duration quenching process for defect screening. The quenching process is designed to identify those defects that will precisely (and negatively) affect long-term, cryogenic part operation. This quenching process occurs at a temperature that is at least

  8. Modern NDT techniques applied to composite parts

    International Nuclear Information System (INIS)

    There are many Non Destructive Testing (NDT) techniques used on qualifying the composite made parts. a) Composite materials pose significant challenge for defect detection, since they are non-homogenous and anisotropic b) in nature. Throughout their life cycle composites are susceptible to the formation of many defects such as delamination, matrix cracking, fiber fracture, fiber pullout and impact damage. Various NDT methods are used for qualifying composite made parts like Ultrasonic, Radiographic, and Eddy Current etc. However, the latest techniques are Infra-Red Thermography, Neutron Radiography, Optical Holography, X-ray Computed Tomography and Acoustic Microscopy. This paper deals with each type of the methods and their suitability for different kinds of composites. (author)

    2015-03-01

    Clinical imaging protocols play an important role in the provision of high-quality care in nuclear medicine. It is imperative that all nuclear medicine facilities have protocols for every procedure performed. However, creating protocols that are detailed, unambiguous, and consistent is often easier said than done. Properly written protocols help to ensure that nuclear medicine procedures are performed in a standardized, reproducible manner so that patients receive high-quality care. This 2-part article provides technologists with a framework for composing comprehensive protocols. Part 1 discusses the secrets to successfully composing protocols ensuring they are detailed and step-by-step along with the importance of basing protocols on evidence from published guidelines and peer-reviewed literature. The components and important aspects of clinical imaging protocols are detailed. PMID:25613336

  12. How US utilities upgraded spare parts programmes

    International Nuclear Information System (INIS)

    Improvements in utility procurement practices during the past two years have mollified Nuclear Regulatory Commission (NRC) staff concerns about the potential for fraudulent or substandard spare parts making their way into nuclear power plants in the USA. Several cases of bogus parts being sold to utilities in the late 1980s had raised fears that a major problem existed with utilities' procurement programmes. But the cases highlighted the potential for fraud in the supply of replacement equipment for nuclear plants, and they put utilities under a spotlight. Today, the problem does not look as serious as it appeared at first. No new cases of fraud or misrepresented equipment have surfaced, and the NRC staff, impressed with a voluntary programme launched by the industry, now believes new regulations are unnecessary.

Prior to assembly, the pattern plate has an aligning portion, which has one or more holes through which reusable alignment pins are inserted. These alignment pins enter kinematic joints disposed on the mounting frame, which serve to precisely align the pattern plate to the mounting frame. After the pattern plate has been secured to the mounting frame, the aligning portion can be detached from the pattern plate. The alignment pins can be reused at a later time. In some embodiments, the pattern plate can later be removed from the mounting frame, so that the mounting frame may be reused.

  14. Fixed-film processes. Part 2

    International Nuclear Information System (INIS)

    Recently, full scale fixed-film or mixed suspended have been applied in many wastewater treatments plants. These processes no longer depend on biomass settle ability and can be used to improve the performance of existing plants as required by more stringent discharge permit limits, especially for nutrients suspended solids. Also, processes may work at high rates making is possible to build small footprint installations. Fixed-film processes include trickling filters (and combined suspended and fixed-films processes), rotating biological contactors, biological aerated submerged, filters moving bed reactors, fluidized bed reactors. In the first part, the theoretical based governing fixed-film processes are briefly outlined, with some simple examples of calculations, underlining the main differences with conventional activate sludge processes. In the second part, the most common types of reactors are reviewed

    Small-part sonography refers to the display of small, near-surface structures using high-frequency linear array transducers. Traditional applications for small part ultrasound imaging include visualization and differential diagnostic evaluation in unclear superficial bodily structures with solid, liquid and mixed texture, as well as similar structures in nearly superficial organs such as the thyroid glands and the testes. Furthermore indications in the head and neck regions are the assessment of the outer CSF spaces in infants, the sonography of the orbit, the sonography of the walls of the large neck vessels, the visualization of superficially situated lymph nodes and neoplasms. Clinical evidence concludes that sonography, having of all imaging modalities the highest spatial resolution in the millimeter- and micrometer range (100–1000 μm), can be considered the best suited technique for examining superficial pathological formations and near-surface organs. In addition, it delivers important information about characteristic, often pathognomonic tissue architecture in pathological processes.

    2016-05-01

    This research investigates the problem of the part supplier performance evaluation in a major Japanese automotive plant in Thailand. Its current evaluation scheme is based on experiences and self-opinion of the evaluators. As a result, many poor performance suppliers are still considered as good suppliers and allow to supply parts to the plant without further improvement obligation. To alleviate this problem, the brainstorming session among stakeholders and evaluators are formally conducted. The result of which is the appropriate evaluation criteria and sub-criteria. The analytical hierarchy process is also used to find suitable weights for each criteria and sub-criteria. The results show that a newly developed evaluation method is significantly better than the previous one in segregating between good and poor suppliers.

    2006-08-01

    Full Text Available Purpose: Presentation of the possibilities of application of a new manufacturing method, called wedge rollsrolling (WRR in forming of axi – symmetrical hollowed parts.Design/methodology/approach: The research work was done in a specially designed laboratory rolling millLUW-2. During the research, hollowed parts from steel were rolled in hot forming conditions. Basic kinematicaland force parameters of the process were noticed during rolling.Findings: On the basis of the conducted research it was stated that the WRR method could be used for formingof hollowed parts with the precision compared with the precision obtained in the typical cross wedge rollingprocesses (CWR. At the same time, it was proved that this method could be used for rolling from billets withthe wall thinner than the wall given in the CWR.Research limitations/implications: The research were limited to the wedges with spreading angles withinrange of β = (5° ÷ 9°, with the constant values of forming angle α = 30° and relative reduction ratio δ = 1.45.In the future, it is planned to analyse the influence of changes of angle α and relative reduction ratio δ on theWRR process.Practical implications: The conducted research can be used for designing of a new industrial method of metalforming of hollowed parts.Originality/value: The innovation of this solution is based on the application of only one wedge for forming.Because of that, the WRR method is cheaper for implementation than used so far CWR processes. This methodcan be applied mainly in automotive and aviation industries.

    2000-11-01

    Osteoarthritis is the most common form of arthritis, affecting millions of people in the United States. It is a complex disease whose etiology bridges biomechanics and biochemistry. Evidence is growing for the role of systemic factors, such as genetics, diet, estrogen use, and bone density, and local biomechanical factors, such as muscle weakness, obesity, and joint laxity. These risk factors are particularly important in the weight-bearing joints, and modifying them may help prevent osteoarthritis-related pain and disability. Major advances in management to reduce pain and disability are yielding a panoply of available treatments ranging from nutriceuticals to chondrocyte transplantation, new oral anti-inflammatory medications, and health education. This article is part 2 of a two-part summary of a National Institutes of Health conference that brought together experts in osteoarthritis from diverse backgrounds and provided a multidisciplinary and comprehensive summary of recent advances in the prevention of osteoarthritis onset, progression, and disability. Part 2 focuses on treatment approaches; evidence for the efficacy of commonly used oral therapies is reviewed and information on alternative therapies, including nutriceuticals and acupuncture, is presented. Biomechanical interventions, such as exercise and bracing, and behavioral interventions directed toward enhancing self-management are reviewed. Current surgical approaches are described and probable future biotechnology-oriented approaches to treatment are suggested. PMID:11074906

    The rivers are in some circumstances part of the ground battlefield. Microseisms induced at the riverbed or ground at the river surrounding might be consequence of military activities (military ground transports, explosions, troop's activities, etc). Vibrations of those fluid-solid structures are modeled in terms of solid displacement and change of fluid pressure. This time varying fluid pressure in river, which originates from ground microseisms, is possible to detect with hydrophones. Therefore, hydroacoustic measurements in rivers enables detecting, identification and localization various types of military noisy activities at the ground as and those, which origin is in the river water (hydrodynamics of water flow, wind, waves, river vessels, etc). In this paper are presented river ambient noise measurements of the three great rivers: the Danube, the Sava and the Tisa, which flows in north part of Serbia in purpose to establish limits in detection of the ground vibrations in relatively wide frequency range from zero to 20 kHz. To confirm statement that the river is a part of ground battlefield, and that hydroacoustic noise is possible to use in detecting and analyzing ground microseisms induced by civil or military activities, some previous collected data of hydroacoustic noise measurement in the rivers are used. The data of the river ambient noise include noise induced by civil engineering activities, that ordinary take place in large cities, noise that produced ships and ambient noise of the river when human activities are significantly reduced. The poly spectral method was used in analysis such events.

  3. The metallurgy of superalloys part 2

    International Nuclear Information System (INIS)

    This is part II of the report titled 'the metallurgy of superalloys'. It deals with the effect of heat treatment and operating conditions (thermal exposure and environment) on the mechanical properties of superalloys. The heat treatment is important in the development of superalloys through that it controls type, amount, size shape and distribution of the precipitate and the grain size of the matrix. The thermal exposure leads to reduction in the amount of the primary carbides and to precipitation of secondary carbides. Also it leads to the agglomeration and coarsening of gamma or the transformation of gamma phase to phase. The environment may lead to the internal oxidation, carburization, decarburization or sulphidization of the superalloys which may result in the degradation of their mechanical properties. This part gives also an example of applications of superalloys in the field of nuclear reactors especially high temperature-gas cooled reactors. Joined with this part a table which contains the major superalloys including its chemical analysis, creep rupture strength and some of its applications. 1 tab

  4. Manufacturing of GLARE Parts and Structures

    Science.gov (United States)

    Sinke, J.

    2003-07-01

    GLARE is a hybrid material consisting of alternating layers of metal sheets and composite layers, requiring special attention when manufacturing of parts and structures is concerned. On one hand the applicable manufacturing processes for GLARE are limited, on the other hand, due to the constituents and composition of the laminate, it offers new opportunities for production. One of the opportunities is the manufacture of very large skin panels by lay-up techniques. Lay-up techniques are common for full composites, but uncommon for metallic structures. Nevertheless, large GLARE skin panels are made by lay-up processes. In addition, the sequences of forming and laminating processes, that can be selected, offer manufacturing options that are not applicable to metals or full composites. With respect to conventional manufacturing processes, the possibilities for Fibre Metal Laminates in general, are limited. The limits are partly due to the different failure modes, partly due to the properties of the constituents in the laminate. For machining processes: the wear of the cutting tools during machining operations of GLARE stems from the abrasive nature of the glass fibres. For the forming processes: the limited formability, expressed by a small failure strain, is related to the glass fibres. However, although these manufacturing issues may restrict the use of manufacturing processes for FMLs, application of these laminates in aircraft is not hindered.

    Clinical preception in practice plays a significant role in both registered and practical nurse studies. As such, the cooperation between the faculty and working life is important to narrow the theory-practice gap, with emphasis being placed on a student-oriented approach promoting self-direction and lifelong learning. The aim of this project was to develop the preceptorship at five different units within the health-care sector in western Finland by implementing an action research (AR) approach. This article is the first of a two-part article on the project, focusing on a cultural analysis and the development of preception models conducted within the project. The five units participating in the study were the following: a long-term care ward in the community, a ward for people with dementia, a geriatric ward, a medical ward and a surgical ward representing specialised care. The starting point of the study was a cultural analysis, which was made in all the five units to obtain a 'bottom-up' perspective. In each of the five units 3-5 nurses were appointed to become members of the core groups. This meant that all the units would start from the perspective of their own working environment when creating a preception model that would fit into their particular workplace. During this process, the participants received continuous support from the researchers. Several workshops and seminars were also arranged to further support the core groups and staff. The models were implemented and tested during the academic year 2010-2011 followed by an evaluation of the project. The evaluation results will be presented in the second part of the two-part article. The project showed that reflective practice and critical thinking can be improved through an AR approach.

    This research tries to make advancement in GPS signal processing to estimate the interseismic vertical deformation field at western part of Sumatra Island. The data derived by Continuous Global Positioning System (CGPS) from Badan Informasi Geospasial (BIG) between 2010 and 2012. GPS Analyze at Massachusetts Institute of Technology (GAMIT) software and Global Kalman Filter (GLOBK) software are used to process the GPS signal to estimate the vertical velocities of the CGPS station. In order to minimize noise due to atmospheric delay, Vienna Mapping Function 1 (VMF1) is used as atmospheric parameter model and include daily IONEX file provided by the Center for Orbit Determination in Europe (CODE) as well. It improves GAMIT daily position accuracy up to 0.8 mm. In a second step of processing, the GLOBK is used in order to estimate site positions and velocities in the ITRF08 reference frame. The result shows that the uncertainties of estimated displacement velocity at all CGPS stations are smaller than 1.5 mm/yr. The subsided deformation patterns are seen at the northern and southern part of west Sumatra. The vertical deformation at northern part of west Sumatra indicates postseismic phase associated with the 2010 and 2012 Northern Sumatra earthquakes and also the long-term postseismic associated with the 2004 and 2005 Northern Sumatra earthquakes. The uplifted deformation patterns are seen from Bukit Tinggi to Seblat which indicate a long-term interseismic phase after the 2007 Bengkulu earthquake and 2010 Mentawai earthquake. GANO station shows a subsidence at rate 12.25 mm/yr, indicating the overriding Indo-Australia Plate which is dragged down by the subducting Southeast Asian Plate.

    The authors propose a new welding technique and machinery for the thermal contact welding thermoplastic parts of electric oil well pumps which efficiently creates welds of higher quality than those resulting from ultrasonic welding and also permits the use of cheaper and more readily available thermoplastics such as polyethylene and polypropylene which do not lend themselves to ultrasonic welding. The annual savings to the industry as a result of the implementation of their technique, and of the substitution of polypropylene for polyamide, amounts to 150,000 rubles.

  9. Integration-by-parts identities in FDR

    International Nuclear Information System (INIS)

    Four-Dimensionally Regularized/Renormalized (FDR) integrals play an increasingly important role in perturbative loop calculations. Thanks to them, loop computations can be performed directly in four dimensions and with no ultraviolet counterterms. In this paper I prove that integration-by-parts (IBP) identities based on simple integrand differentiation can be used to find relations among multi-loop FDR integrals. Since algorithms based on IBP are widely applied beyond one loop, this result represents a decisive step forward towards the use of the FDR approach in multi-loop calculations.

    A higher degree of ecological safety in ship traffic depends on onboard measures as well as reception facilities on shore, treatment of ship generated wastes and preparedness for combating emergency oil spills. The problem is particularly acute in the North Sea Route (NSR) due to high vulnerability of the Arctic ecosystems, low rates of natural degradation of oil, absence of forward coastal infrastructure, low efficiency of oil combating means in ice conditions and severe climatic conditions. Oil spills in the NSR are likely to occur as the offshore production and transportation of oil increase. Therefore a regional Oil Spill Contingency Plan (OSCP) is being constructed and developed on 3 levels: 1) Development of concept, definition of response organisations and their technical ability (Part I). 2) Collection and analysis of information, development of scenarios of probable oil spills, clearing of the funding mechanism and basis for additional outside co-operation from other Russian regions and circumpolar countries (part II). 3) Development of NSR OSCP (part III). The present report (part I) provides the plan concept, rescue organisations and data on types and amounts of the oil spill combating technical means and of the floating facilities available in the NSR or it`s vicinity. The concept takes into account subdivision of the Route, interaction and links between responsible organisations, realities of the Russian Arctic such as transport, communications, energy, labour resources etc. and requirements of the IMO and of the International Convention OPRC 90. According to Russian legislation implementation of combating operations at sea is the responsibility of the Maritime Pollution Control and Salvage Administration that consists of a Central Administration and basin emergency divisions situated in Murmansk and Nahodka. The body is responsible for carrying out cleaning operations at sea from installations and may be assisted by resources and means of the co

We explain and demonstrate how the inclusion of selected unoccupied states in the definition of the WFs can improve both their localization and symmetry...... properties. A systematic selection of the relevant unoccupied states is achieved by minimizing the spread of the resulting WFs. The method is applied to a silicon cluster, a copper crystal, and a Cu(100) surface with nitrogen adsorbed. In all cases we demonstrate the existence of a set of WFs...

    A rotating electric machine in which the armature winding thereof and other parts are supported by a liquid to withstand the mechanical stresses applied during transient overloads and the like. In particular, a narrow gap is provided between the armature winding and the stator which supports it and this gap is filled with an externally pressurized viscous liquid. The liquid is externally pressurized sufficiently to balance the static loads on the armature winding. Transient mechanical loads which deform the armature winding alter the gap dimensions and thereby additionally pressurize the viscous liquid to oppose the armature winding deformation and more nearly uniformly to distribute the resulting mechanical stresses.

    An integral part of providing effective feedback to pharmacy residents occurs during the evaluation process. Residency evaluation involves measuring and documenting performance as it relates to standardized residency outcomes, goals, and learning objectives. Evaluations may be formative or summative and include the preceptor's evaluation of the resident's performance, the resident's self-assessments, and the resident's evaluation of the preceptor and learning experience. Evaluations are more structured than feedback, and they involve documentation of the verbal feedback that was provided throughout the learning experience.

  12. Short history of PACS (Part II: Europe)

    International Nuclear Information System (INIS)

    Although the concept of picture archiving and communications systems (PACS) was developed in Europe during the latter part of the 1970s, no working system was completed at that time. The first PACS implementations took place in the United States in the early 1980s, e.g. at Pennsylvania University, UCLA, and Kansas City University. Some more or less successful PACS developments also took place in Europe in the 1980s, particularly in the Netherlands, Belgium, Austria, the United Kingdom, France, Italy, Scandinavia, and Germany. Most systems could be characterized by their focus on a single department, such as radiology or nuclear medicine. European hospital-wide PACS with high visibility evolved in the early 1990s in London (Hammersmith Hospital) and Vienna (SMZO). These were followed during the latter part of the 1990s by approximately 10-20 PACS installations in each of the major industrialized countries of Europe. Wide-area PACS covering several health care institutions in a region are now in the process of being implemented in a number of European countries. Because of limitations of space some countries, for example, Denmark, Finland, Spain, Greece, as well as Eastern European countries, etc. could not be appropriately represented in this paper.

    Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years. PMID:27176184

    International Nuclear Information System (INIS)

    The report presents data obtained through a radioactivity survey. Various environmental and dietary materials are collected for analysis. Rain and dry fallout are collected monthly. Airborne dust is collected every three months. Service water samples are taken semiyearly. Freshwater is taken once a year (fishing season). Soil samples are taken once a year from two layers at different depths. Sea water is collected once a year at fixed stations where the effect of terrestrial fresh water from rivers is expected to be negligibly small. Sea sediments are collected once a year in the same area as that for the sea water sample. A full one day ordinary diet including three meals, water and tea for five persons is collected semiyearly as a sample of 'total diet'. Polished rice is collected in producing districts and in consuming areas. Raw milk is collected in producing districts and commercial milk is purchased in consuming districts. Vegetable are collected once a year in producing and consuming districts. Tea samples are also collected once a year. Fish, shellfish and seaweeds are collected once a year. Test solutions are prepared from these samples. Strontium-90 and cesium-137 are separated and subjected to quantitative determination. Results obtained are tabulated. This part (Part 2) presents data on dietary materials. (N.K.)

  16. The metallurgy of superalloys part 1

    International Nuclear Information System (INIS)

    This is part I of the report titled 'the metallurgy of superalloys'. In this part the structure, phases and systems of superalloys are reviewed. The role of alloying elements in the design of superalloys and the mechanical properties of superalloys are also reviewed. Superalloys are important in high temperature technology, especially above 700 degree c. They are 'super' mainly because their creep and stress rupture resistances are very high. Superalloys are based on an austenitic matrix including secondary phases, mainly gamma precipitates, inter and intragranular carbides mainly M23 C6 and M6 C. They are classified into three systems, Ni-base, Fe-Ni base and Ce-base alloys. Different alloying elements mainly Cr, Mo, Al, Ti are added to increase the strength either by solid solution hardening (Cr, Mo, Al), precipitation hardening (A 1, Ti to produce gamma) or by dispersion hardening (Cr, Mo to form M23 C6 and M6 C carbides) and to increase the oxidation resistance (Cr, Al). 3 tab., 2 fig

  17. Study of laser cladding nuclear valve parts

    International Nuclear Information System (INIS)

    The mechanism of laser cladding is discussed by using heat transfer model of laser cladding, heat conduction model of laser cladding and convective transfer mass model of laser melt-pool. Subsequently the laser cladding speed limit and the influence of laser cladding parameters on cladding layer structure is analyzed. A 5 kW with CO2 transverse flow is used in the research for cladding treatment of sealing surface of stop valve parts of nuclear power stations. The laser cladding layer is found to be 3.0 mm thick. The cladding surface is smooth and has no such defects as crack, gas pore, etc. A series of comparisons with plasma spurt welding and arc bead welding has been performed. The results show that there are higher grain grade and hardness, lower dilution and better performances of resistance to abrasion, wear and of anti-erosion in the laser cladding layer. The new technology of laser cladding can obviously improve the quality of nuclear valve parts. Consequently it is possible to lengthen the service life of nuclear valve and to raise the safety and reliability of the production system

    The pathologies of tendon and ligament attachments are called enthesopathies. One of its types is enthesitis which is a characteristic sign of peripheral spondyloarthropathy. Clinical diagnosis of enthesitis is based on rather non-specific clinical signs and results of laboratory tests. Imaging examinations are highly promising. Numerous publications prove that enthesitis can be differentiated from other enthesopathic processes in an ultrasound examination or magnetic resonance imaging. However, some reports indicate the lack of histological criteria, specific immunological changes and features in imaging examinations that would allow the clinical diagnosis of enthesitis to be confirmed. The first part of the publication presents theories on the etiopathogenesis of enthesopathies: inflammatory, mechanical, autoimmune, genetic and associated with the synovio-entheseal complex, as well as theories on the formation of enthesophytes: inflammatory, molecular and mechanical. The second part of the paper is a review of the state-of-the-art on the ability of imaging examinations to diagnose enthesitis. It indicates that none of the criteria of inflammation used in imaging medicine is specific for this pathology. As enthesitis may be the only symptom of early spondyloarthropathy (particularly in patients with absent HLA-B27 receptor), the lack of its unambiguous picture in ultrasound and magnetic resonance scans prompts the search for other signs characteristic of this disease and more specific markers in imaging in order to establish diagnosis as early as possible.

    Cutaneous findings are not uncommonly a concomitant finding in patients afflicted with gastrointestinal (GI) diseases. The dermatologic manifestations may precede clinically evident GI disease. Part I of this 2-part CME review focuses on dermatologic findings as they relate to hereditary and nonhereditary polyposis disorders and paraneoplastic disorders. A number of hereditary GI disorders have an increased risk of colorectal carcinomas. These disorders include familial adenomatous polyposis, Peutz-Jeghers syndrome, and juvenile polyposis syndrome. Each disease has its own cutaneous signature that aids dermatologists in the early diagnosis and detection of hereditary GI malignancy. These disease processes are associated with particular gene mutations that can be used in screening and to guide additional genetic counseling. In addition, there is a group of hamartomatous syndromes, some of which are associated with phosphatase and tensin homolog (PTEN) gene mutations, which present with concurrent skin findings. These include Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, and Cronkhite-Canada syndrome. Finally, paraneoplastic disorders are another subcategory of GI diseases associated with cutaneous manifestations, including malignant acanthosis nigricans, Leser-Trélat sign, tylosis, Plummer-Vinson syndrome, necrolytic migratory erythema, perianal extramammary Paget disease, carcinoid syndrome, paraneoplastic dermatomyositis, and paraneoplastic pemphigus. Each of these disease processes have been shown to be associated with an increased risk of GI malignancy. This underscores the important role of dermatologists in the diagnosis, detection, monitoring, and treatment of these disorders while consulting and interacting with their GI colleagues.

    hypothesis of the existence of phenomenon change trends, the next step in the methodology of forecasting is the determination of a specific growth curve that describes the regularity of the development in time. These curves of growth are obtained by the analytical representation (expression of dynamic lines. There are two basic stages in the process of expression and they are: - The choice of the type of curve the shape of which corresponds to the character of the dynamic order variation - the determination of the number of values (evaluation of the curve parameters. The most widespread method of forecasting is the trend extrapolation. The basis of the trend extrapolation is the continuing of past trends in the future. The simplicity of the trend extrapolation process, on the one hand, and the absence of other information on the other hand, are the main reasons why the trend extrapolation is used for forecasting. The trend extrapolation is founded on the following assumptions: - The phenomenon development can be presented as an evolutionary trajectory or trend, - General conditions that influenced the trend development in the past will not undergo substantial changes in the future. Spare parts demand forecasting is constantly being done in all warehouses, workshops, and at all levels. Without demand forecasting, neither planning nor decision making can be done. Demand forecasting is the input for determining the level of reserve, size of the order, ordering cycles, etc. The question that arises is the one of the reliability and accuracy of a forecast and its effects. Forecasting 'by feeling' is not to be dismissed if there is nothing better, but in this case, one must be prepared for forecasting failures that cause unnecessary accumulation of certain spare parts, and also a chronic shortage of other spare parts. All this significantly increases costs and does not provide a satisfactory supply of spare parts. The main problem of the application of this model is that each

    The article presents a retrospective history of the ALPHA series of publications. This action-research project (later called "cooperative research") on literacy and basic education is divided into three periods of seven years each. The first one, "Construction", involved assisting the nascent literacy movement in Québec and Canada by given it a theoretical, critical and ideological basis. In the second period, "Ruptures", the project distanced itself somewhat from the literacy movement, whose success, according to the author, was dubious. During the same period ALPHA systematised its critical function and internationalised its field of research. The third phase, "Wanderings", involved a different research paradigm, in which the project explored basic education at community level in connection with local development initiatives. This biographical/autobiographical account ends with the last publication ALPHA 2000, evincing an ecological vision for alternative education and sustainable communities, partly documented in the Arab countries.

    Karma Snyder, a project manager at NASA's John C. Stennis Space Center, was a senior design engineer on the RL10 liquid rocket engine that powered the Centaur, the upper stage of the rocket used in NASA's Lunar CRater Observation and Sensing Satellite (LCROSS) mission in October 2009. Part of the LCROSS mission was to search for water on the moon by striking the lunar surface with a rocket stage, creating a plume of debris that could be analyzed for water ice and vapor. Snyder's work on the RL10 took place from 1995 to 2001 when she was a senior design engineer with Pratt & Whitney Rocketdyne. Years later, she sees the project as one of her biggest accomplishments in light of the LCROSS mission. 'It's wonderful to see it come into full service,' she said. 'As one of my co-workers said, the original dream was to get that engine to the moon, and we're finally realizing that dream.'

    Nearly 80 essential oils (including 2 jasmine absolutes) have caused contact allergy. Fifty-five of these have been tested in consecutive patients suspected of contact dermatitis, and nine (laurel, turpentine, orange, tea tree, citronella, ylang-ylang, sandalwood, clove, and costus root) showed greater than 2% positive patch test reactions. Relevance data are generally missing or inadequate. Most reactions are caused by application of pure oils or high-concentration products. The clinical picture depends on the responsible product. Occupational contact dermatitis may occur in professionals performing massages. The (possible) allergens in essential oils are discussed. Several test allergens are available, but patients should preferably be tested with their own products. Co-reactivity with other essential oils and the fragrance mix is frequent, which may partly be explained by common ingredients. Patch test concentrations for essential oils are suggested.

    We study experimentally shuttlecocks dynamics. In this part we show that shuttlecock trajectory is highly different from classical parabola. When one takes into account the aerodynamic drag, the flight of the shuttlecock quickly curves downwards and almost reaches a vertical asymptote. We solve the equation of motion with gravity and drag at high Reynolds number and find an analytical expression of the reach. At high velocity, this reach does not depend on velocity anymore. Even if you develop your muscles you will not manage to launch the shuttlecock very far because of the ``aerodynamic wall.'' As a consequence you can predict the length of the field. We then discuss the extend of the aerodynamic wall to other projectiles like sports balls and its importance.

    Full Text Available Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF: neurofibromatosis type 1 (NF1, neurofibromatosis type 2 (NF2 and schwannomatosis (SCH. NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1.

    The first biosimilar version of a biologic agent used to treat psoriasis (infliximab) entered the Spanish market on February 16 of this year, and more biosimilars can be expected to follow in the coming months and years. Logically, this new situation will have economic repercussions and alter prescribing patterns among dermatologists. In this second part of the review, we will look at several somewhat contentious issues, such as the extrapolation of indications, interchangeability, and automatic substitution. We will also review the biosimilars with indications for psoriasis currently in the clinical development pipeline and assess their potential to offer comparable efficacy and safety to the reference product while contributing to the sustainability of the public health care system.

    2015-07-01

    The diffuse cystic lung diseases have a broad differential diagnosis. A wide variety of pathophysiological processes spanning the spectrum from airway obstruction to lung remodeling can lead to multifocal cyst development in the lung. Although lymphangioleiomyomatosis and pulmonary Langerhans cell histiocytosis are perhaps more frequently seen in the clinic, disorders such as Birt-Hogg-Dubé syndrome, lymphocytic interstitial pneumonia, follicular bronchiolitis, and light-chain deposition disease are increasingly being recognized. Obtaining an accurate diagnosis can be challenging, and management approaches are highly disease dependent. Unique imaging features, genetic tests, serum studies, and clinical features provide invaluable clues that help clinicians distinguish among the various etiologies, but biopsy is often required for definitive diagnosis. In part II of this review, we present an overview of the diffuse cystic lung diseases caused by lymphoproliferative disorders, genetic mutations, or aberrant lung development and provide an approach to aid in their diagnosis and management.

    The diffuse cystic lung diseases (DCLDs) are a group of pathophysiologically heterogenous processes that are characterized by the presence of multiple spherical or irregularly shaped, thin-walled, air-filled spaces within the pulmonary parenchyma. Although the mechanisms of cyst formation remain incompletely defined for all DCLDs, in most cases lung remodeling associated with inflammatory or infiltrative processes results in displacement, destruction, or replacement of alveolar septa, distal airways, and small vessels within the secondary lobules of the lung. The DCLDs can be broadly classified according to underlying etiology as those caused by low-grade or high-grade metastasizing neoplasms, polyclonal or monoclonal lymphoproliferative disorders, infections, interstitial lung diseases, smoking, and congenital or developmental defects. In the first of a two-part series, we present an overview of the cystic lung diseases caused by neoplasms, infections, smoking-related diseases, and interstitial lung diseases, with a focus on lymphangioleiomyomatosis and pulmonary Langerhans cell histiocytosis.

    Full Text Available El objetivo de este trabajo es discutir la importancia de los estudios de arqueología terrestre y subacuática como parte de un mismo proceso de interpretación del pasado. Se entiende que el registro arqueológico puede hallarse actualmente en una variedad de ambientes tanto terrestres como subacuáticos a causa de varias razones, como por ejemplo las oscilaciones de los niveles de agua ocurridas entre el Pleistoceno Final y el Holoceno Medio. Por lo tanto, se propone que para su recuperación debe utilizarse una metodología adaptada al medio ambiente en el cual se encuentre. En este sentido, es importante la interpretación integral del paisaje para acceder a la comprensión de la diversidad ambiental en la que se puede emplazar un sitio arqueológico, y en consecuencia poder “bucear” un registro integrado.

  1. Absorption chillers: Part of the solution

    International Nuclear Information System (INIS)

    Acid rain, ozone depletion, global warming, and implementation economics are considered as they relate to the advisability of expanding the application of absorption chillers. Introductory and background information are provided to put the discussion in the proper context. Then all four issues are discussed separately as they relate to absorption chillers. Acid rain and ozone depletion concerns, and implementation economics, are found to support the expanded use of absorption chillers. The global warming concern is found to be more of a gray area, but the areas of benefit correspond well with the conditions of greatest economic advantage. All things considered, absorption chillers are believed to be part of the environmental and economic solution. It is further believed that integrated resource planning (IRP) processes that consider electric and gas technologies on an equal footing would come to the same conclusion for many regions of the United States. 9 refs., 3 tabs

  4. Toxicological Models Part B: Environmental Models

    Science.gov (United States)

    Garric, Jeanne; Thybaud, Eric

    Assessment of ecotoxicological risks due to chemical substances is based in part on establishing concentration-response relationships for different organisms, including plants, invertebrates, and vertebrates living on land, fresh water, or sea water. European regulations for assessing the risks due to chemical products thus recommend the measurement of toxic effects on at least three taxons (algae, crustacea, fish) [1]. The assessment becomes more relevant when based upon a variety of different organisms, with a range of different biological and ecological features (autotrophic or heterotrophic, benthic or pelagic habitat, and different modes of reproduction, growth, respiration, or feeding, etc.), but also when it describes the effects of contaminants on sensitive physiological functions such as growth and reproduction, which determine the balance of populations of terrestrial and aquatic species in their environment.

  5. RA reactor operation in 1991, Part 1

    International Nuclear Information System (INIS)

    During the previous period RA reactor was not operated because the Committee of Serbian ministry for health and social care has cancelled the operation licence in August 1984. The reason was the non existing emergency cooling system and lack of appropriate filters in the special ventilation system. Control and maintenance of the reactor instrumentation and tools was done regularly but dependent on the availability of the spare parts. In order to enable future reliable operation of the RA reactor, according to new licensing regulations, during 1991, three major tasks were fulfilled: building of the new emergency cooling system, reconstruction of the existing ventilation system, and renewal of the reactor power supply system. Renewal of the reactor instrumentation was started but but it is behind the schedule in 1991 because the delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA for political reasons. In 1991 most of the existing RA reactor instrumentation was dismantled, only the part needed for basic measurements when reactor is not operated, was maintained. Training of the existing personnel was done regularly, but lack of financial support prevented employment of new workers that would be needed for operation in shifts and regular maintenance

  6. Computer hardware for radiologists: Part 2

    International Nuclear Information System (INIS)

    Computers are an integral part of modern radiology equipment. In the first half of this two-part article, we dwelt upon some fundamental concepts regarding computer hardware, covering components like motherboard, central processing unit (CPU), chipset, random access memory (RAM), and memory modules. In this article, we describe the remaining computer hardware components that are of relevance to radiology. “Storage drive” is a term describing a “memory” hardware used to store data for later retrieval. Commonly used storage drives are hard drives, floppy drives, optical drives, flash drives, and network drives. The capacity of a hard drive is dependent on many factors, including the number of disk sides, number of tracks per side, number of sectors on each track, and the amount of data that can be stored in each sector. “Drive interfaces” connect hard drives and optical drives to a computer. The connections of such drives require both a power cable and a data cable. The four most popular “input/output devices” used commonly with computers are the printer, monitor, mouse, and keyboard. The “bus” is a built-in electronic signal pathway in the motherboard to permit efficient and uninterrupted data transfer. A motherboard can have several buses, including the system bus, the PCI express bus, the PCI bus, the AGP bus, and the (outdated) ISA bus. “Ports” are the location at which external devices are connected to a computer motherboard. All commonly used peripheral devices, such as printers, scanners, and portable drives, need ports. A working knowledge of computers is necessary for the radiologist if the workflow is to realize its full potential and, besides, this knowledge will prepare the radiologist for the coming innovations in the ‘ever increasing’ digital future

    Recent Findings from Audits, New Technology Data Reviews a) Disabled Chip Burn-ins A recent audit for a QML device discovered that the chip was disabled during the static burn-in, thus it was not drawing any current. Recommendation: For new SMDs add a statement within the burn-in paragraphs stating that the parts shall be kept in their enabled state during the burn-in. b) Class Q 160-hr/125oC Burn-in This is being interpreted as a static burn-in (even for CMOS technology). Recommendation: Provide clarification in MIL-STD-883, Test Method 5004. c) At Frequency (Dynamic) Burn-ins Test equipment limitation is being cited for not doing burn-ins at the application frequency. Recommendation: The burn-in task group to discuss and provide guidance. When the SMD says that the part can be used at 200 MHz, then doing burn-in at 6 MHz (cited as burn-in equipment limitation frequency) is not going to be meaningful! d) Two Static Burn-ins Some manufacturers are doing electrical testing between the two static burn-ins, whereas others do electricals after completing both static burn-ins. Recommendation: Provide clarification in MIL-STD-883, Test Method 5004. e) Thermal Imaging For a device with hot spots, the thermal resistance, junction-to-case, would be much higher than the guidelines given in MIL-STD-1835. One of the suppliers used thermal imaging to find hot spots on the die. Recommendation: Assign a task group to evaluate the effectiveness of thermal imaging at the product development stage.

    2016-07-01

    Synchrotron X-ray tomography (SXRT) has been applied to the study of defects within three-dimensional printed titanium parts. These parts were made using the Arcam EBM(®) (electron beam melting) process which uses powdered titanium alloy, Ti64 (Ti alloy with approximately 6%Al and 4%V) as the feed and an electron beam for the sintering/welding. The experiment was conducted on the Imaging and Medical Beamline of the Australian Synchrotron. The samples represent a selection of complex shapes with a variety of internal morphologies. Inspection via SXRT has revealed a number of defects which may not otherwise have been seen. The location and nature of such defects combined with detailed knowledge of the process conditions can contribute to understanding the interplay between design and manufacturing strategy. This fundamental understanding may subsequently be incorporated into process modelling, prediction of properties and the development of robust methodologies for the production of defect-free parts.

    Martins E Silva, J

    2009-01-01

    The present work summarizes the more elucidating aspects on the foundations and the practice of the medicine in Antique Mesopotamia, since the invention of the writing, more than 5000 thousand years ago, and the beginning of our era. The first part of the article includes a brief perspective about the political and social evolution that characterized those archaic civilizations, as well as the inventions and knowledge further used by the following Humanity's generations. Most of what is known on the subject, as well as the history and political-social events that occurred in the region during that remote epoch, resulted of the laborious decoding of about half a million small clay plates or fragments with text engravings in cuneiform characters that were discovered since the middle of the XIX century in the ruins of the main cities of the Babylonian and Assyrian empires. The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. In that base, the medicine began by being preventive, by the use of appropriate amulets, or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of an ãshipu (clergyman-exorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances. In case of failing, the patients (as well as individuals or rein leaders) could fall back upon a priest diviner (bârû) who, by examination of the organs of an animal especially sacrificed for the effect

  7. On-line alkali monitoring - Part 1

    International Nuclear Information System (INIS)

    As a consequence of the increased knowledge of the environmental impact of combustion based heat and power generation, the use of renewable biofuels will be increased. An obstacle associated to biofuel combustion compared to other fuels is the large release of alkali. Alkali compounds in flue gases are known to cause severe operational problems. Three of the major problems are; fouling of superheating tubes (causing reduced heat transfer and possibly corrosion), agglomeration of the bed material in fluidized beds, and poisoning of SCR catalysts. Yet another alkali related problem arises when, in order to increase the electric efficiency of combustion power plants, combined-cycle technology is used. Alkali vapour present in the fuel gas for the gas turbine is condensed to particles which increase corrosion and erosion of the turbine blades. The research on ash related operational problems has to be extended in order to ensure future use of biofuels in heat and power generation. In all successful research, adequate tools are necessary. To investigate ash related problems the key issue is to be able to perform continuous alkali measurements. This pilot study has investigated the need of continuous alkali measurements, which alkali species are harmful in the different applications and also available instrumentation capable of measuring the specific alkali species. The report gives a short summary presenting alkali related operational problems. In addition a schematic overview is given, showing the alkali species that possibly can exist in various parts of the power plant. 48 refs, 13 figs, 4 tabs

  8. Compressor Part II: Volute Flow Predictions

    Directory of Open Access Journals (Sweden)

    Yu-Tai Lee

    1999-01-01

    Full Text Available A numerical method that solves the Reynolds-averaged Navier-Stokes equations is used to study an inefficient component of a shipboard air-conditioning HCFC-124 compressor system. This high-loss component of the centrifugal compressor was identified as the volute through a series of measurements given in Part I of the paper. The predictions were made using three grid topologies. The first grid closes the connection between the cutwater and the discharge diffuser. The other two grids connect the cutwater area with the discharge diffuser. Experiments were performed to simulate both the cutwater conditions used in the predictions. Surface pressures along the outer wall and near the inlet of the volute were surveyed for comparisons with the predictions. Good agreements between the predicted results and the measurements validate the calculations. Total pressure distributions and flow stream traces from the prediction results support the loss distribution through the volute. A modified volute configuration is examined numerically for further loss comparison.

Siamo andati alla ricerca dei significati reconditi delle parole usate nei testi pubblicitari, e abbiamo scoperto, che dietro il tutto si muove una macchina organizzativa perfetta, che si serve di accurate ricerche motivazionali e si fa aiutare dalle scienze sociali per potere, sempre e in ogni caso, avere un potere di suggestione sul consumatore. La nostra ricerca ha voluto esaminare in che modo il mercato del biologico e del transgenico viene presentato al consumatore, quali tecniche pubblicitarie impiega e di che metodi persuasivi si avvale, ricordandoci sempre che la pubblicità, per sua stessa natura, sta dalla parte di chi 'produce' e non di chi 'consuma'.

    It has been shown that the MARLAP (Multi-Agency Radiological Laboratory Analytical Protocols) for estimating the Currie detection limit, which is based on 'critical values of the non-centrality parameter of the non-central t distribution', is intrinsically biased, even if no calibration curve or regression is used. This completed the refutation of the method, begun in Part 2. With the field cleared of obstructions, the true theory underlying Currie's limits of decision, detection and quantification, as they apply in a simple linear chemical measurement system (CMS) having heteroscedastic, Gaussian measurement noise and using weighted least squares (WLS) processing, was then derived. Extensive Monte Carlo simulations were performed, on 900 million independent calibration curves, for linear, 'hockey stick' and quadratic noise precision models (NPMs). With errorless NPM parameters, all the simulation results were found to be in excellent agreement with the derived theoretical expressions. Even with as much as 30% noise on all of the relevant NPM parameters, the worst absolute errors in rates of false positives and false negatives, was only 0.3%.

  15. Lipids: Part of the tangled web

    Krauss, R.M.

    1992-08-01

    Analysis of LDL subclasses by non-denaturing gradient gel electrophoresis has led to the identification of a subclass pattern characterized by predominance of small LDL, designated LDL subclass pattern B. The prevalence of pattern B in the general population is approximately 25%, but varies as a function of age and gender, being relatively uncommon in children and in premenopausal women. The remainder of the population has a predominance of larger LDL (pattern A) or an intermediate pattern. Our findings indicate that LDL subclass pattern B is an integral part of the ``tangled web`` of interrelated coronary disease risk factors associated with insulin resistance. It may be that the pathologic features of this lipoprotein profile, including the relative atherogenicity of small, dense LDL and IDL, contribute importantly to the increased risk of cardiovascular disease in subjects with insulin resistance and hypertension. Furthermore, pattern B serves as a marker for a common genetic trait which may underlie a substantial portion of the familial predisposition to coronary artery disease in the general population. Studies of hormonal, dietary, and pharmacologic influences on expression of this atherogenic phenotype should lead to more effective identification and management of high-risk individuals, and improved approaches to disease prevention in high-risk families.

    Full Text Available Nessa primeira parte do trabalho referente ao estudo dos Procamallanus brasileiros, os autores propoêm que Spirocamallanus Olsen, 1952, seja aceito apenas como um bom subgênero, baseando-se exclusivamente no aspecto de cápsula bucal. Assi, Spirocamallanus identifica os camalanídeos de cápsula bucal com lâminas espiraladas ou outras estruturas semelhantes, enquanto que Procamallanus se aplicaria aos de cápsula bucal lisa. Quanto às demais subdivisões existentes para o gênero, apoiadas em aspecto e quantidade de espículos, são consideradas resultado de um critério bastante arbitrário para conservarem-se válidas, visto serem os espículos caracteres sujeitos a diversas interpretações por parte dos especialistas, devido à fragilidade que os toma tão sujeitos a modificações no grupo dos camalanídeos. Três espécies são aqui tratadas: Procamallanus (Spirocamallanus rarus Travassos, Artigas & Pereira, 1928, Procamallanus (Spirocamallanus pimelodus, e Procamallanus (Spirocamallanus intermedius. As duas últimas são propostas como novas. Procamallanus (S. pimelodus é comparada a Procamallanus (Spirocamallanus olseni Campana-Rouget & Razahihelissoa, 1965, dela se distinguindo, principalmente, por apresentar o rebordo da asa caudal franjado e fortemente musculoso. Procamallanus (S. intermedius aproxima-se unicamente de Procamallanus (S. rarus, por apresentar o espículo maior com bifurcação distal e dela se afasta pelo maior número e menor espessura das lâminas espiraladas na cápsula bucal. Para Procamallanus (S. rarus é apresentada a descrição da fêmea, a redescrição do macho, salientando-se pela primeira vez no gênero, o aspecto singular do espículo maior, aspecto esse também observado ao se lidar com Procamallanus (S. intermedius, depois de se ter tido acesso ao exemplar tipo e único de Procamallanus (S. rarus.

  18. Decontamination Process of Internal Part Pipes - 13442

    International Nuclear Information System (INIS)

    The Marcoule Site, created in 1955 is one of the first nuclear sites in France. It combines the activities of the Research Centre of the French Atomic Energy Commission (CEA) and AREVA industrial operations. Today, a large part of the operations on this site consists of the cleaning and the dismantling of nuclear Installations, once the end of their life cycle has been reached. An example can be the reprocessing plant UP1. This unit, started in 1958 has been stopped in 1997 and its dismantling started quickly thereafter. Technical challenges of the UP1 dismantling are mainly linked to a very high risk of exposure due to a large variety of contaminated equipments and residuals of fission products, potential sources of irradiation. The dismantling of Hall 71 is a typical example of such challenge. This paper will present a solution developed by AREVA Clean-Up business unit, in collaboration with COFIM Industry, to remove contamination incrusted inside the pipes before starting the cutting operations, thus reducing irradiation risk.

    2016-01-01

    Women are often under-represented in IT. And yet, at any age and whatever their level and background, it is a field that can arouse much interest.    To overcome this under-representation, the R0SEH1PSters community organises Django workshops targeted at women to introduce them to the world of coding and technology by teaching them how to successfully create a blog application and deploy it to the internet. And who knows, a spark of interest in the newly-discovered IT world may develop into a shine! The aim of Django Girls is also to increase the diversity within the industry. The mentors are mainly female volunteers who bring their passion to the workshop and are part of the awesome atmosphere attendees can feel during each event. Workshops have been organised worldwide regularly since 2014. Hosted by IdeaSquare and supported by the CERN IT department and the Diversity team, the Geneva workshop will take place in the evening on Friday evening, 26 February, and al...

  1. Bisphenol A in edible part of seafood

    Directory of Open Access Journals (Sweden)

    Adele Repossi

    2016-05-01

    Full Text Available Bisphenol A (BPA is a man-made compound, mainly used as a monomer to produce polycarbonate (PC, epoxy resins, non-polymer additives to other plastics, which have many food related applications, such as food storage containers, tableware and internal coating of cans, as well as non-food applications such as electronic equipment, construction materials and medical devices. BPA exposure can occur when the residual monomer migrates into packaged food and beverages. Moreover, due to the ubiquitous presence of this compound, the general population can be exposed to environmental sources such as water, air and soil. Many studies have investigated the potential health hazards associated with BPA, which can elicit toxic and cancerogenic effects on humans. According to the European Food Safety Authority opinion, diet is considered to be the main source of exposure, especially canned food; moreover, among non-canned food, meat and fish products have the highest levels of BPA contamination. This review focuses on BPA contamination in seafood, analysing worldwide literature (from January 2010 to October 2015 on BPA contamination of edible parts. The authors try to identify differences between canned and non-canned seafood in literature, and gaps in the state of art. The data evaluated underline that all concentrations for both canned and non-canned seafood were below the specific migration limit set by the European Community Directive for BPA in food. Moreover, the canned seafood is more contaminated than the non-canned one.

  2. Compact tokamak reactors. Part 1 (analytic results)

    International Nuclear Information System (INIS)

    We discuss the possible use of tokamaks for thermonuclear power plants, in particular tokamaks with low aspect ratio and copper toroidal field coils. Three approaches are presented. First we review and summarize the existing literature. Second, using simple analytic estimates, the size of the smallest tokamak to produce an ignited plasma is derived. This steady state energy balance analysis is then extended to determine the smallest tokamak power plant, by including the power required to drive the toroidal field, and considering two extremes of plasma current drive efficiency. The analytic results will be augmented by a numerical calculation which permits arbitrary plasma current drive efficiency; the results of which will be presented in Part II. Third, a scaling from any given reference reactor design to a copper toroidal field coil device is discussed. Throughout the paper the importance of various restrictions is emphasized, in particular plasma current drive efficiency, plasma confinement, plasma safety factor, plasma elongation, plasma beta, neutron wall loading, blanket availability and recirculating electric power. We conclude that the latest published reactor studies, which show little advantage in using low aspect ratio unless remarkably high efficiency plasma current drive and low safety factor are combined, can be reproduced with the analytic model

  4. Integrated concurrent utilization quality review, Part one.

    Science.gov (United States)

    Caterinicchio, R P

    1987-01-01

    This article is the first of a two-part series which argues for the concurrent management of the appropriateness, necessity, and quality of patient care. Intensifying scrutiny by the credentialing groups, the PROs and all third-party payors underscores the vital need to implement cost-effective information systems which integrate the departmentalized functions of patient-physician profiling, DRG case-mix analyses, length of stay monitoring, pre-admission/admission and continued stay review, discharge planning, risk management, incident reporting and quality review. In the domain of physician performance regarding admitting and practice patterns, the ability to exercise concurrent utilization-quality review means early detection and prevention of events which would otherwise result in denials of payment and/or compromised patient care. Concurrent utilization-quality review must, by definition, be managerially invasive and focused; hence, it is integral to maintaining the integrity of the services and product lines offered by the provider. In fact, if PPO status is a marketing agenda, then the institutional objectives of cost-effectiveness, productivity, value, and competitiveness can only be achieved through concurrent utilization-quality review.

  5. Trust Control of VTOL Aircraft Part Deux

    Dugan, Daniel C.

    2014-01-01

    Thrust control of Vertical Takeoff and Landing (VTOL) aircraft has always been a debatable issue. In most cases, it comes down to the fundamental question of throttle versus collective. Some aircraft used throttle(s), with a fore and aft longitudinal motion, some had collectives, some have used Thrust Levers where the protocol is still "Up is Up and Down is Down," and some have incorporated both throttles and collectives when designers did not want to deal with the Human Factors issues. There have even been combinations of throttles that incorporated an arc that have been met with varying degrees of success. A previous review was made of nineteen designs without attempting to judge the merits of the controller. Included in this paper are twelve designs entered in competition for the 1961 Tri-Service VTOL transport. Entries were from a Bell/Lockheed tiltduct, a North American tiltwing, a Vanguard liftfan, and even a Sikorsky tiltwing. Additional designs were submitted from Boeing Wichita (direct lift), Ling-Temco-Vought with its XC-142 tiltwing, Boeing Vertol's tiltwing, Mcdonnell's compound and tiltwing, and the Douglas turboduct and turboprop designs. A private party submitted a re-design of the Breguet 941 as a VTOL transport. It is important to document these 53 year-old designs to preserve a part of this country's aviation heritage.

    From 8.30 to 9.30 p.m. on Saturday, 26 March 2011, the Globe of Science and Innovation will be plunged into darkness to mark CERN's participation in Earth Hour. A growing number of countries and cities across the planet are involved in this global initiative against climate change, which was launched by the WWF in 2007.   The lights on the Globe were switched off for the 2009 Earth Hour event. Along with individuals, companies and tourist attractions in thousands of towns and cities all over the world participating in the fourth annual Earth Hour event, CERN will turn off the lights of the Globe for 60 minutes at 8.30 p.m. on Saturday 26 March. CERN's participation in the initiative is one of several examples of its commitment to respect the environment and keep its ecological footprint to the minimum. A recent example under the green transport heading was the replacement of part of CERN's petrol vehicle fleet with cars running on natural gas with a view to reducing air pollution.

    International Nuclear Information System (INIS)

    The publication is aimed at providing radioactivity survey data in Japan. Part 1 covered environmental materials, including rain, dry fallout, airborne dust, service water, freshwater, soil, and sea sediments. Samples were collected from 42 locations during the period between April 1991 and April 1992, and were sent to the Japan Chemical Analysis Center for radiochemical analysis. Strontium-90 and cesium-137 in these environmental materials are tabulated. The maximum concentrations of strontium-90 and cesium-137 were 0.40±0.035 MBq/Km2 and 0.22±0.031 MBq/Km2, in rain and dry fallout; 0.0018±0.00075 mBq/m3 and 0.0011±0.00066 mBq/m3 in airborne dust; 5.5±0.28 mBq/l and 0.42±0.11 mBq/l in service water; 3.5±0.22 mBq/l and 0.33±0.10 mBq/l in freshwater; 1100±30 MBq/Km2 and 3500±70 MBq/Km2 in soil; 0.34±0.093 Bq/kg and 7.2±0.29 Bq/kg in sea sediments respectively. Annual changes in the concentrations of both strontium-90 and cesium-137 from 1988 through 1992 are given in figures. (J.P.N.)

  9. [Medicine in ancient Mesopotamia - part 2].

    Martins E Silva, J

    2010-01-01

    The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. Insofar, the medicine began by being preventive, by the use of appropriate amulets or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of a approximately shipu (clergymanexorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances. In case of failing, the patients (as well as common healthy individuals or rule leaders) could fall back upon a priest diviner (bârû) that, by examination of the organs of an animal especially sacrificed for, would give a final decision about the disease or the future. Besides this more occult facet, nourished in religious faiths and in the magic, the medicine of Ancient Mesopotamia included rational knowledge, certainly as the result of systematic patients observation and semiotic interpretation. From those observations and knowledge referred to the Sumerian period, carefully logged, refined and transmitted to the following generations, it was built a valuable group of texts with the description of symptoms, signs, diagnosis and prognostic of the most common diseases, still identifiable in the present.

    2001-01-01

    Objective:To investigate the role of Mdm2 expression in hepatocellular carcinoma.Methods: Streptavidin-peroxidase conjugation method (SP)was used to observe the expression of Mdm2 and p53 proteins in 61 cases of hepatocellular carcinoma(HCC)and 59 cases of corresponding paracancerous tissues,among which p53 mutations in exons 5~8 were detected in 21 cases by PCR-SSCP.Results:Positive nuclear P53 and Mdm2 immunostains were demonstrated in 57.38% and 26.23% of HCC,1.69% and 3.39% of corresponding paracancerous tissues respectively.The expression of p53 and Mdm2 proteins in hepatocellular carcinoma was significantly higher than that in paracancerous tissues(P<0.01).The expression of P53 and Mdm2 was not significantly correlated.42.86% of hepatocellualr carcinomas showed mutations in exon 7 of p53 gene,and no mutation was found in exons 5,6,8 and paracancerous tissues. 66.67% of mutational cases had P53 overexpression and 11.11%(1/9)showed overexpression of both P53 and Mdm2,Mdm2 overexpression also appeared in 25% of cases without mutations.Conclusions:Mdm2-induced p53 inactivation and p53 gene mutation play an important role in carcinogenesis of hepatocellular carcinoma.Tumorigenic property of Mdm2 itself,together with p53 mutation,may take part in hepatocarcinogenesis.

  11. Information as a part of radiation protection

    International Nuclear Information System (INIS)

    The increasing range of application of ionizing radiation in many different areas requires the needs for further education and training. Unfortunately, some aspects of application of ionizing radiation are not planed and announced for all involved personnel-like in military conflicts, when radiation and radioactivity are used as a new kind of ammunition. In that situation there is no time for formal and planned education. During the NATO strikes on Serbia and Montenegro in 1999. depleted uranium (D.U.) ammunition was used. Before that, it was used in Gulf War in 1991. for the first time. Faced with the health consequences of Gulf War for the soldiers of both sides, which were mainly attributed to D.U., Military Medical Service in the Army of Serbia and Montenegro, prepared educational material for the soldiers who could be employed in the area of the D.U. contamination. Considering the information/knowledge as very important part of radiation protection, booklet was prepared and distributed before the NATO strikes on Serbia and Montenegro. In this paper we present the booklet prepared for the military personnel. In the simplified way the nature of D.U. is explained. Some practical aspects of protection and prevention in D.U. contaminated area-how to avoid and minimize radiological hazard of D.U. in the battlefield, as well as how to avoid long-term hazards of D.U., are presented. It is also explained when to ask for medical care and what kind of examination would be necessary in the case of D.U. contamination. 5AUTHORS

    Hilli, Yvonne; Melender, Hanna-Leena

    2015-09-01

    Clinical preception in practice plays a significant role in the education of both Registered Nurses and practical nurses. This study presents the evaluation of an interprofessional research and development project (2009-2103) on clinical preceptorship between two universities of applied sciences, two vocational institutes and four healthcare organisations in western Finland. The research question was as follows: How did the participants evaluate the process and outcomes of developing preceptorship through an action-research approach? The primary target group consisted of professionals within the healthcare sector and nursing teachers at the universities of applied sciences and the vocational institutes. The five units represented in the healthcare organisations functioned as clinical practice placements for both nursing and practical nursing students, with Registered Nurses and practical nurses acting as their preceptors. Each unit developed a unique preceptorship model to answer their specific needs. The models were implemented and tested during one academic year followed by a quantitative (a 4-point scale) and qualitative evaluation of the process. The models are presented in another article, and the evaluation results are presented in this article. The evaluation showed that preceptorship has become an important and accepted part of work, including the practice of starting any preception at a unit with a thorough introduction. The project's emphasis on critical thinking, reflection and focus on ethics were valued by the staff. Pedagogical further education should be arranged on a regular basis to strengthen the knowledge base of the preceptors. Furthermore, enough time for preceptorship should be allocated, as it is a pedagogical duty. The implication of this project is that more cooperation between different stake holders is needed, in order to narrow the gap between theory and praxis. PMID:25833207

  15. Charged NUT field : [Part] I. Motion of test particles and [Part] II. Cosmic censorship

    International Nuclear Information System (INIS)

    Some properties of the charged NUT field are studied. In the first part of the paper, some general aspects of the charged NUT field have been investigated using uncharged and charged particles. The behaviour of the particles near the singularity has also been considered. In the second part of the paper, the charged NUT sources in the context of cosmic censorship hypothesis are studied. Motion of charged particles in the equatorial plane and along the axis is considered. From this investigation the interesting result is discovered that by such a bombardment of charged test particles, the existing event horizons cannot be destroyed but, in contrast to the Reissner-Nordstrom field, naked singularities do not get enveloped by event horizons.

  19. The part task of the part-spacing paradigm is not a pure measurement of part-based information of faces.

    Directory of Open Access Journals (Sweden)

    Qi Zhu

    Full Text Available BACKGROUND: Faces are arguably one of the most important object categories encountered by human observers, yet they present one of the most difficult challenges to both the human and artificial visual systems. A variety of experimental paradigms have been developed to study how faces are represented and recognized, among which is the part-spacing paradigm. This paradigm is presumed to characterize the processing of both the featural and configural information of faces, and it has become increasingly popular for testing hypotheses on face specificity and in the diagnosis of face perception in cognitive disorders. METHODOLOGY/PRINCIPAL FINDINGS: In two experiments we questioned the validity of the part task of this paradigm by showing that, in this task, measuring pure information about face parts is confounded by the effect of face configuration on the perception of those parts. First, we eliminated or reduced contributions from face configuration by either rearranging face parts into a non-face configuration or by removing the low spatial frequencies of face images. We found that face parts were no longer sensitive to inversion, suggesting that the previously reported inversion effect observed in the part task was due in fact to the presence of face configuration. Second, self-reported prosopagnosic patients who were selectively impaired in the holistic processing of faces failed to detect part changes when face configurations were presented. When face configurations were scrambled, however, their performance was as good as that of normal controls. CONCLUSIONS/SIGNIFICANCE: In sum, consistent evidence from testing both normal and prosopagnosic subjects suggests the part task of the part-spacing paradigm is not an appropriate task for either measuring how face parts alone are processed or for providing a valid contrast to the spacing task. Therefore, conclusions from previous studies using the part-spacing paradigm may need re-evaluation with

    -threshold nerve propagation. By expanding the range of mathematical operations to include fractional calculus, we can develop new and potentially useful functional relationships for modeling complex biological systems in a direct and rigorous manner. In Part 2 of this review (Crit Rev Biomed Eng 2004; 32(1):105-193), fractional calculus was applied to problems in nerve stimulation, dielectric relaxation, and viscoelastic materials by extending the governing differential equations to include fractional order terms. In this third and final installment, we consider distributed systems that represent shear stress in fluids, heat transfer in uniform one-dimensional media, and subthreshold nerve depolarization. Classic electrochemical analysis and impedance spectroscopy are also reviewed from the perspective of fractional calculus, and selected examples from recent studies in neuroscience, bioelectricity, and tissue biomechanics are analyzed to illustrate the vitality of the field.

  1. Radioactivity survey data in Japan, part 2

    International Nuclear Information System (INIS)

    The publication is aimed at providing radioactivity survey data in environmental and dietary materials in Japan. Part 2 gives dietary materials, consisting of total diet, rice, milk, vegetables, sea fish, freshwater fish, shellfish, and seaweeds. Samples were collected from 37 sampling locations during the period between August 1988 and March 1989, and were sent to the Japan Chemical Analysis Center for radiochemical analysis. Strontium-90 and cesium-137 in these dietary materials are tabulated. The maximum concentrations of strontium-90 and cesium-137 were as follows: 0.12±0.012 Bq/p·d and 0.16±0.012 Bq/p·d, respectively, for total diet; 0.0000±0.0084 Bq/Kgwet and 0.42±0.019 Bq/Kgwet for rice (producing districts); 0.0000±0.0084 Bq/Kgwet and 0.048±0.0091 Bq/Kgwet for rice (consuming districts); 0.059±0.008 Bq/l and 0.26±0.013 Bq/l for milk (producing districts for domestic program); 0.14±0.013 Bq/l and 0.19±0.011 Bq/l for milk (producing districts for WHO program); 0.057±0.008 Bq/l and 0.15±0.010 Bq/l for milk (consuming districts); 0.97±0.032 Bq/Kgwet and 0.062±0.010 Bq/Kgwet for vegetables (producing districts); 0.52±0.024 Bq/Kgwet and 0.051±0.009 Bq/Kgwet for vegetables (consuming districts); 0.043±0.010 Bq/Kgwet and 0.34±0.017 Bq/Kgwet for sea fish; 0.96±0.032 Bq/Kgwet and 0.066±0.009 Bq/Kgwet for freshwater fish; 0.017±0.019 Bq/Kgwet and 0.027±0.011 Bq/Kgwet for shellfish; and 0.031±0.011 Bq/Kgwet and 0.12±0.10 Bq/Kgwet for seaweeds. Yearly changes in the concentrations of both strontium-90 and cesium-137 from 1985 through 1989 are given in figures. (N.K.)

  2. Minimizing Glovebox Glove Breaches: PART II.

    As a matter of good business practices, a team of glovebox experts from Los Alamos National Laboratory (LANL) has been assembled to proactively investigate processes and procedures that minimize unplanned breaches in the glovebox, e.g., glove failures. A major part of this effort involves the review of glovebox glove failures that have occurred at the Plutonium Facility and at the Chemical and Metallurgy Research Facility. Information dating back to 1993 has been compiled from formal records. This data has been combined with information obtained from a baseline inventory of about 9,000 glovebox gloves. The key attributes tracked include those related to location, the glovebox glove, type and location of breaches, the worker, and the consequences resulting from breaches. This glovebox glove failure analysis yielded results in the areas of the ease of collecting this type of data, the causes of most glove failures that have occurred, the effectiveness of current controls, and recommendations to improve hazard control systems. As expected, a significant number of breaches involve high-risk operations such as grinding, hammering, using sharps (especially screwdrivers), and assembling equipment. Surprisingly, tasks such as the movement of equipment and material between gloveboxes and the opening of cans are also major contributions of breaches. Almost half the gloves fail within a year of their install date. The greatest consequence for over 90% of glovebox glove failures is alpha contamination of protective clothing. Personnel self-monitoring at the gloveboxes continues to be the most effective way of detecting glovebox glove failures. Glove failures from these tasks can be reduced through changes in procedures and the design of remote-handling apparatus. The Nuclear Materials Technology Division management uses this information to improve hazard control systems to reduce the number of unplanned breaches in the glovebox further. As a result, excursions of contaminants

  3. A Tracking Sun Photometer Without Moving Parts

    Strawa, Anthony W.

    2012-01-01

    This innovation is small, lightweight, and consumes very little electricity as it measures the solar energy attenuated by gases and aerosol particles in the atmosphere. A Sun photometer is commonly used on the Earth's surface, as well as on aircraft, to determine the solar energy attenuated by aerosol particles in the atmosphere and their distribution of sizes. This information is used to determine the spatial and temporal distribution of gases and aerosols in the atmosphere, as well as their distribution sizes. The design for this Sun photometer uses a combination of unique optics and a charge coupled device (CCD) array to eliminate moving parts and make the instrument more reliable. It could be selfcalibrating throughout the year. Data products would be down-welling flux, the direct-diffuse flux ratio, column abundance of gas phase constituents, aerosol optical depth at multiple-wavelengths, phase functions, cloud statistics, and an estimate of the representative size of atmospheric particles. These measurements can be used to obtain an estimate of aerosol size distribution, refractive index, and particle shape. Incident light is received at a light-reflecting (inner) surface, which is a truncated paraboloid. Light arriving from a hemispheric field of view (solid angle 2 steradians) enters the reflecting optic at an entrance aperture at, or adjacent to, the focus of the paraboloid, and is captured by the optic. Most of this light is reflected from an inner surface. The light proceeds substantially parallel to the paraboloid axis, and is detected by an array detector located near an exit aperture. Each of the entrance and exit apertures is formed by the intersection of the paraboloid with a plane substantially perpendicular to the paraboloid axis. Incident (non-reflected) light from a source of limited extent (the Sun) illuminates a limited area on the detector array. Both direct and diffuse illumination may be reflected, or not reflected, before being received on

    Based on the inner character analysis of interpart, detail modification and assembly relation of mechanical connecting element, the idea, which extends the feature modeling of part to the interpart feature modeling for assembly purpose, is presented, and virtual-part-based connecting element modeling is proposed. During the assembly modeling, base parts are modified by the Boolean subtraction between the virtual part and the part to be connected. Dynamic matching algorithm, which is based on list database, is designed for dynamic extension and off-line editing of connecting part and virtual part, and design rules of connecting element is encapsulated by the virtual part. A prototyped software module for rapid design of connecting elements is implemented under self-developed CAD/CAM platform-SuperMan.

    2007-01-01

    In communication, information, and other industries, three-part tariffs are increasingly popular. A three-part tariff is defined by an access price, an allowance, and a marginal price for any usage in excess of the allowance. Empirical nonlinear pricing studies have focused on consumer choice under two-part tariffs. We show that consumer behavior differs under three-part tariffs and assess how consumer demand uncertainty impacts tariff choice. We develop a discrete/continuous model of choice ...

  13. Engineering BioBrick vectors from BioBrick parts

    Directory of Open Access Journals (Sweden)

    Knight Thomas F

    2008-04-01

    Full Text Available Abstract Background The underlying goal of synthetic biology is to make the process of engineering biological systems easier. Recent work has focused on defining and developing standard biological parts. The technical standard that has gained the most traction in the synthetic biology community is the BioBrick standard for physical composition of genetic parts. Parts that conform to the BioBrick assembly standard are BioBrick standard biological parts. To date, over 2,000 BioBrick parts have been contributed to, and are available from, the Registry of Standard Biological Parts. Results Here we extended the same advantages of BioBrick standard biological parts to the plasmid-based vectors that are used to provide and propagate BioBrick parts. We developed a process for engineering BioBrick vectors from BioBrick parts. We designed a new set of BioBrick parts that encode many useful vector functions. We combined the new parts to make a BioBrick base vector that facilitates BioBrick vector construction. We demonstrated the utility of the process by constructing seven new BioBrick vectors. We also successfully used the resulting vectors to assemble and propagate other BioBrick standard biological parts. Conclusion We extended the principles of part reuse and standardization to BioBrick vectors. As a result, myriad new BioBrick vectors can be readily produced from all existing and newly designed BioBrick parts. We invite the synthetic biology community to (1 use the process to make and share new BioBrick vectors; (2 expand the current collection of BioBrick vector parts; and (3 characterize and improve the available collection of BioBrick vector parts.

    In this paper, we study the problem of semantic part segmentation for animals. This is more challenging than standard object detection, object segmentation and pose estimation tasks because semantic parts of animals often have similar appearance and highly varying shapes. To tackle these challenges, we build a mixture of compositional models to represent the object boundary and the boundaries of semantic parts. And we incorporate edge, appearance, and semantic part cues into the compositional...

  10. SETI as a part of Big History

    Science.gov (United States)

    Maccone, Claudio

    2014-08-01

    Big History is an emerging academic discipline which examines history scientifically from the Big Bang to the present. It uses a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It is taught at some universities. In a series of recent papers ([11] through [15] and [17] through [18]) and in a book [16], we developed a new mathematical model embracing Darwinian Evolution (RNA to Humans, see, in particular, [17] and Human History (Aztecs to USA, see [16]) and then we extrapolated even that into the future up to ten million years (see 18), the minimum time requested for a civilization to expand to the whole Milky Way (Fermi paradox). In this paper, we further extend that model in the past so as to let it start at the Big Bang (13.8 billion years ago) thus merging Big History, Evolution on Earth and SETI (the modern Search for ExtraTerrestrial Intelligence) into a single body of knowledge of a statistical type. Our idea is that the Geometric Brownian Motion (GBM), so far used as the key stochastic process of financial mathematics (Black-Sholes models and related 1997 Nobel Prize in Economics!) may be successfully applied to the whole of Big History. In particular, in this paper we derive part of GBM. This makes SETI a subset of our Big History Theory based on GBMs: just as the GBM is the “movie” unfolding in time, so the Statistical Drake Equation is its “still picture”, static in time, and the GBM is the time-extension of the Drake Equation. Darwinian Evolution on Earth may be easily described as an increasing GBM in the number of living species on Earth over the last 3.5 billion years. The first of them was RNA 3.5 billion years ago, and now 50

    2016-07-01

    Synchrotron X-ray tomography has been applied to the study of titanium parts fabricated by additive manufacturing (AM). The AM method employed here was the Arcam EBM(®) (electron beam melting) process which uses powdered titanium alloy, Ti64 (Ti alloy with approximately 6%Al and 4%V), as the feed and an electron beam for the sintering/welding. The experiment was conducted on the Imaging and Medical Beamline of the Australian Synchrotron. Samples were chosen to examine the effect of build direction and complexity of design on the surface morphology and final dimensions of the piece. PMID:27359150

  16. CAD APPROACH FOR PLASTIC MOULD PARTING DIRECTIONS OPTIMIZATION

    Institute of Scientific and Technical Information of China (English)

    1998-01-01

    A CAD approach which can optimize and automate the parting direction determination is presnted. The approach is based on the geometrical and topological information of the solid modelling of the plastic moulded part in order to select a pair of optimal parting directions of a two-plate mould which minimizes the number of side cores. The shell of a part is divided into inter-influential regions and non-influential faces in the mould design point of view. Through analyzing and computing the accessibility direction cones of the inter-influential regions, the optimal parting directions can be determined automatically.

  17. IN MY OPINION: Taking part matters

    Science.gov (United States)

    Stone, Christine

    2000-09-01

    demanding syllabuses for pre-university exams. In years gone by, some of our most gifted students happened to be taught by some of our most able teachers, and together they tackled the old Scholarship-level papers. The old O-level work gave students a solid grounding in classical mechanics, electricity and magnetism, with lots of sums on which to anchor the concepts. Those who enjoyed this aspect of the science could launch into A-level studies of Maths, Physics, Chemistry and/or Further Maths, and relish the challenges hidden in the syllabuses. Advanced level aims have changed. Mathematical elements have been played down; traditional proofs and applications may be referred to but are no longer required learning for the candidates. The modular system allows less repetitive revision and consolidation of ideas so that students are not required to immerse themselves in the subject in the same way as a generation ago. Does this matter? The `new way' hopes to attract some students into Physics and Engineering who would have been intimidated by the rigour and commitment required to do well in the old system. The single-minded student has a wealth of information available to further his or her studies and will not be limited by the dictates of any syllabus. However, without the need to meet exam requirements, many of our most able students have been deprived of the pleasure of advancing their knowledge so far at school, and must wait for a degree course to take up the story. (We should worry if many of these potential scientists get deflected from Physics.) The change in A-level targets inevitably means that the UK is slipping down the IPhO medal table, but in the Olympic tradition it is the taking part that matters. The 31st Olympiad was won by the People's Republic of China, with five gold medals out of five. Heartiest congratulations to them and to Russia, who came second with two gold, two silver and a bronze. The other gold medals went to Hungary (2), India (2), Taiwan (2

  20. Discovery of Quantum structure and A Theory of Everything Part I and Part II

    Science.gov (United States)

    Zhang, Meggie

    2012-10-01

    (Part I) During my research I discovered logical errors in the logic of science and in mathematics. These errors caused scientists missed out important information when interpreting data. This led me to revisit the method of science and the existing results and able to find new information, which lead to the discovery of photon's structure. A ``particle collision illumination'' experiment then provided direct evidence supported the structure. Analysis of the properties of the structure suggested an organized but not-continuous multi-dimension (n-D) space within. Therefore I formed a hypothesis of a not-continuous n-D space structure. In search for evidence, I turned into crystal technology, and found direct evidence supported the hypotesis, then further particle collision found more evidence support this finding. (Part II) Analysis of single electron buildup revealed star and galaxy formation is from a single particle following a predictable pattern. This pattern is also common in matter formation. Analysis of the quantum structure suggested the formation of a larger structure through the space expansion within the structure. Further experiment results support the finding and result revealed the expansion is through space folding. Result also suggested a violation of energy conservation law that energy is created during the formation of matter, and matter itself is moving from a lower energy state to a higher energy state. When putting all information together, I arrived to a theory of everything which gives explanations to all existing phenomenon in the universe including black hole, dark energy, star formation, consciousness.
