A Mechanical Model For The Quantification Of The Effect Of Laser Quenching On Ctod In Steels

The technology of laser quenching is widely used to improve the surface properties of steels in surface engineering. Generally, laser quenching of steels can lead to two important results. One is the generation of residual stress in the surface layer. In general, the residual stress varies from the surface to the interior along the quenched track depth direction, and the residual stress variation is termed as residual stress gradient effect in this work. The other is the change of mechanical properties of the surface layer, such as the increases of the micro-hardness, resulting from the changes of the microstructure of the surface layer. In this work, a mechanical model of a laser-quenched specimen with a crack in the middle of the quenched layer is developed to quantify the effect of residual stress gradient and the average micro-hardness over the crack length on crack tip opening displacement (CTOD). It is assumed that the crack in the middle of the quenched layer is created after laser quenching, and the crack can be a pre-crack or a defect due to some reasons, such as a void, cavity or a micro-crack. Based on the elastic-plastic fracture mechanics theory and using the relationship between the micro-hardness and yield strength, a concise analytical solution, which can be used to quantify the effect of residual stress gradient and the average micro-hardness over the crack length resulting from laser quenching on CTOD, is obtained. The concise analytical solution obtained in this work, cannot only be used as a means to predict the crack driving force in terms of the CTOD, but also serve as a baseline for further experimental investigation of the effect after laser-quenching treatment on fracture toughness in terms of the critical CTOD of a specimen, accounting for the laser-quenching effect. A numerical example presented in this work shows that the CTOD of the quenched can be significantly decreased in comparison with that of the unquenched. (C) 2008 Elsevier B.V. All rights reserved.

Interface Fracture Behavior Of Electroplated Coating On Metal Substrate Under Compressive Strain

The inducement of interface fracture is crucial to the analysis of interfacial adhesion between coating and substrate. For electroplated coating/metal substrate adhering materials with strong adhesion, interface cracking and coating spalling are difficult to be induced by conventional methods. In this paper an improved bending test named as T-bend test was conducted on a model coating system, i.e. electroplated chromium on a steel substrate. After the test, cross-sections of the coated materials were prepared to compare the failure behaviors under tensile strain and compressive strain induced by T-bend test. And the observation results show that coating cracking, interface cracking and partial spalling appear step by step. Based on experimental results, a new method may be proposed to rank the coated materials with strong inter-facial adhesion. (C) 2008 Elsevier B.V. All rights reserved.

Probing single-molecule by surface-enhanced resonance Raman scattering with linearly and circularly polarized laser

Rhodamine 6G (R6G) was incubated in silver sols with different low concentrations and its surface-enhanced resonance Raman scattering (SERRS) spectra, excited by linearly and circularly polarized light, respectively, were studied. At the single-molecule level the SERRS spectra were recorded in 10(-13) M dye colloidal solution. Spectral inhomogeneous behaviors from single-molecule were observed such as spectral polarization, spectral diffusion and intensity fluctuations of vibrational lines. Difference between SERRS spectra of R6G excited by linearly and circularly polarized light and the effect of the polarizing angle of Raman signal relative to the slit of spectrograph on the Raman spectral polarization were analyzed and measured experimentally. Circularly polarized laser and the correction of the polarizing angle of Raman signal are necessary to avoid fake results in the measuring of Raman spectral of single-molecule, which was not noticed in initial papers.

Investigation of nematode Eustrongylides larvae infections in mudfish Clarias gariepinus and C. anguillaris from Bida floodplain of Nigeria

This is the first report and record of the determination whether mudfish Clarias were infected with the larvae of the nematode Eustrongylides. Also, documented the assessment of the socio-economic perceptions of three groups of fisher folks on the economy of infected mudfish Clarias fishing activities. Fifty-six (67.5%) of 83 mudfish Clarias caught by artisanal fisher folks were examined for the presence of the larvae of the nematode Eustrongylides. All the 8 sampled fishing localities in Bida floodplain of Nigeria had a mean intensity and abundance of at least 3 and 1 worm per fish per site, respectively. Two hundred and one (96.2%) of 209 worms recovered were from the musculatures at different depths resulting in undulations on the skin surfaces as grub-like presentations. The three groups of fisher folks assessed encountered economic losses from nematode infected mudfish Clarias which attract much debates or rejections during marketing due to its aesthetically displeasing appearance, faster deterioration, higher fragility in smoked form coupled with poorer taste compared to the wholesome ones. Infected female mudfish Clarias had higher worm burden than the males, for each fishing locality

Sideband manipulation of population inversion in a three-level Λ atomic system

Sideband manipulation of population inversion in a three-level A atomic configuration is investigated theoretically. Compared with the case of a nearly monochromatic field, a population inversion between an excited state and a ground state has been found in a wide sideband intensity range by increasing the difference in frequency between three components. Furthermore, the population inversion can be controlled by the sum of the relative phases of the sideband components of the trichromatic pump field with respective to the phase of the central component. Changing the sum phase from 0 to pi, the population inversion between the excited state and the ground state can increase within nearly half of the sideband intensity range. At the same time, the sideband intensity range that corresponds to the system exhibiting inversion rho(00) > rho 11 also becomes wider evidently.

Zum Auftreten von Geruchs- und Geschmacksabweichungen ("Tainting") bei Frühjahrsheringen (Clupea harengus) aus der Ostsee

An account of the occurrenee of tainting in fish and seafood with special consideration of spring spawning herring from the Baltic Sea (estuary of the river Oder) is given. About 26 % of the herring samples examined by sensory methods showed tainting. In general the intensity of taint was weak or moderate and weaker as observed years ago. Also in fishery products (pickled herring, deep fried herring in marinade) processed from tainted herrings the same or a similar sensory intensity of taint as in the raw material was observed. The source of taint is not dear. A pollution with halogenphenols from the sea water could be possible. In further investigations we will monitor the further development and try to identify the tainting compounds.

Fish species identification in Canned Tuna by DNA Analysis (PCR-SSCP)

DNA in canned tuna is degraded into short fragments of a rew hundred base pairs. The polymerase chain reaction (PCR) was used to amplify short sequences of mitochondrial DNA, which were denatured and analysed by polyacrylamide gel electrophoresis (native PAGE) for detection of single strand conformation polymorphisms. Species specific patterns of DNA bands were obtained for a number of tuna and bonito species. DE: In Thunfischkonserven liegt die DNA in Form kurzkettiger Fragmente von wenigen Hundert Basenpaaren Länge vor. Mit Hilfe der Polymerase-Kettenreaktion (PCR) wurden kurze Sequenzen der mitochondrialen DNA vervielfältigt. Anschließend wurde die gebildete DNA in Einzelsträngen überführt, die durch eine native Polyacrylamidgel-Elektrophorese (PAGE) aufgetrennt wurde. Für eine Reihe von Thunfischen und Boniten ergaben die Einzelstränge artspezifische Bandenmuster, die auf unterschiedliche Konformationen der DNA-Stränge der einzelnen Fischarten zurückzuführen sind.

Bokal sudurkariak gaurko lapurteran

[EUS] Erkidego elebidunetan bi hizkuntzek elkarri nola eragiten dioten ikusiz (funtsean, gure kasuan, hizkuntza nagusiak —gaztelaniak edo frantsesak— euskaran nola eragiten duen), hizkuntza hartzailearen jokamoldeak neur ditzakegu, hark baliatzen dituen bilakaerak eta baliabideak azaltzeko.

ELEBIDUN : un projet de recherche sur l’apprentissage bilingue basque-français

[FR] Depuis plusieurs décennies, il existe une offre de scolarisation en langue basque dans les établissements scolaires du Pays basque nord (Pyrénées Atlantiques). Les élèves qui suivent une scolarité bilingue sont inscrits soit dans un établissement qui pratique la méthode dite immersive (Ikastolak de Seaska) soit dans un modèle à parité horaire dans un établissement public ou privé1. Ainsi, il est possible pour un élève de mener l’apprentissage de la langue basque en parallèle avec celui du français depuis l’école primaire jusqu’au lycée. Cette offre de scolarisation est en développement constant (38 ouvertures sur les 6 dernières années scolaires) et elle concerne aujourd’hui plus d’une école sur deux (58 %), 34 % des élèves du primaire et 43 % des enfants en maternelle.

Análise da região 5 não traduzida (5 utr) em sequências anotadas como trans-sialidase no genoma de Trypanosoma cruzi

A transsialidase é uma glicoproteína de membrana pertencente a uma família de genes de cópia múltipla, envolvida no processo de invasão celular do Trypanosoma cruzi no hospedeiro vertebrado. Esta dissertação foi concebida com um amplo componente analítico que dependia de dados publicamente disponíveis, ou seja, as sequências oriundas do projeto genoma de T. cruzi e cDNAs de trans-sialidase depositadas no Genbank-dbEST. Este componente analítico necessitou ser complementado e ampliado com a obtenção experimental de novas sequências, a partir da metodologia baseada na transcrição reversa acoplada a PCR. Os fragmentos obtidos de cepas de T. cruzi Dm28c (T. cruzi I), Y (T. cruzi II), CL-Brener (T. cruzi II, cepa híbrida), INPA4167 (zimodema III), 3663 (zimodema III) e Colombiana (zimodema III) foram clonados, sequenciados e analisados composicionalmente. Essas sequências foram editadas e alinhadas usando-se o software CLUSTAL X. Em uma seção específica do Genbank, denominada dbEST, buscamos os cDNAs homólogos a trans-sialidase. Esta busca por similaridade foi realizada individualmente com os números de acesso referentes às seqüências supracitadas contra o dbEST utilizando o BLAST a fim de obtermos informações funcionais e evolutivas. Em seguida, desenvolvemos metodologias experimentais que nos permitiu avaliar segmentos da 5 UTR, tais como os sítios de trans-splicing adicionais ou múltiplos em TS e seus respectivos sinais (região rica em polipirimidina), variação composicional e tamanho da região das sequências entre diferentes linhagens de T. cruzi. O resultado dessa averiguação também nos mostrou a quantidade de cDNAs relacionados com a transsialidase no dbEST bem como a relação desses cDNAs com o mini-exon. As cepas do zimodema III apresentaram tamanho médio dos fragmentos de 312 bases, enquanto T. cruzi I e T. cruzi II apresentaram, respectivamente 209 e 218. Trans splicing adicional ou duplicações gênicas com mutações no sítio primário de trans splicing não parece ser um fenômeno exclusivo de algum grupo populacional, embora seja mais evidente em T. cruzi zimodema III.

Subspecies, morphs and clines in the amphipod Gammarus duebeni from fresh and saline waters

The nature and extent of morphological variation within populations of Gammarus duebeni are examined. The exceptional tolerance of G. duebeni to salinities that encompass three orders of magnitude was known in the 19th Century, and has attracted considerable attention from physiologists and ecologists in the 20th Century, including the likelihood that populations in freshwater are distinct from those living in more saline environments. It is concluded that gradual evolution into discrete and readily distinguished subspecies is currently underway, eventually producing several new species in freshwater and saline habitats.
