The Cariris Velhos tectonic event in Northeast Brazil  

NASA Astrophysics Data System (ADS)

The Borborema Province in northeastern South America is a typical Brasiliano-Pan-African branching system of Neoproterozoic orogens that forms part of the Western Gondwana assembly. The province is positioned between the So Luis-West Africa craton to the north and the So Francisco (Congo-Kasai) craton to the south. For this province the main characteristics are (a) its subdivision into five major tectonic domains, bounded mostly by long shear zones, as follows: Mdio Corea, Cear Central, Rio Grande do Norte, Transversal, and Southern; (b) the alternation of supracrustal belts with reworked basement inliers (Archean nuclei + Paleoproterozoic belts); and (c) the diversity of granitic plutonism, from Neoproterozoic to Early Cambrian ages, that affect supracrustal rocks as well as basement inliers. Recently, orogenic rock assemblages of early Tonian (1000-920 Ma) orogenic evolution have been recognized, which are restricted to the Transversal and Southern domains of the Province. Within the Transversal Zone, the Alto Paje terrane locally includes some remnants of oceanic crust along with island arc and continental arc rock assemblages, but the dominant supracrustal rocks are mature and immature pelitic metasedimentary and metavolcaniclastic rocks. Contiguous and parallel to the Alto Paje terrane, the Riacho Gravat subterrane consists mainly of low-grade metamorphic successions of metarhythmites, some of which are clearly turbiditic in origin, metaconglomerates, and sporadic marbles, along with interbedded metarhyolitic and metadacitic volcanic or metavolcaniclastic rocks. Both terrane and subterrane are cut by syn-contractional intrusive sheets of dominantly peraluminous high-K calc-alkaline, granititic to granodioritic metaplutonic rocks. The geochemical patterns of both supracrustal and intrusive rocks show similarities with associations of mature continental arc volcano-sedimentary sequences, but some subordinate intra-plate characteristics are also found. In both the Alto Paje and Riacho Gravat terranes, TIMS and SHRIMP U-Pb isotopic data from zircons from both metavolcanic and metaplutonic rocks yield ages between 1.0 and 0.92 Ga, which define the time span for an event of orogenic character, the Cariris Velhos event. Less extensive occurrences of rocks of Cariris Velhos age are recognized mainly in the southernmost domains of the Province, as for example in the Poo Redondo-Maranc terrane, where arc-affinity migmatite-granitic and meta-volcano-sedimentary rocks show U-Pb ages (SHRIMP data) around 0.98-0.97 Ga. For all these domains, Sm-Nd data exhibit TDM model ages between 1.9 and 1.1 Ga with corresponding slightly negative to slightly positive ?Nd( t) values. These domains, along with the Borborema Province as a whole, were significantly affected by tectonic and magmatic events of the Brasiliano Cycle (0.7-0.5 Ga), so that it is possible that there are some other early Tonian rock assemblages which were completely masked and hidden by these later Brasiliano events. Cariris Velhos processes are younger than the majority of orogenic systems at the end of Mesoproterozoic Era and beginning of Neoproterozoic throughout the world, e.g. Irumide belt, Kibaride belt and Namaqua-Natal belt, and considerably younger than those of the youngest orogenic process (Ottawan) in the Grenvillian System. Therefore, they were probably not associated with the proposed assembly of Rodinia. We suggest, instead, that Cariris Velhos magmatism and tectonism could have been related to a continental margin magmatic arc, with possible back-arc associations, and that this margin may have been a short-lived (<100 m.y.) leading edge of the newly assembled Rodinia supercontinent.

Brazilian mosquito (Diptera: Culicidae) fauna: I. Anopheles species from Porto Velho, Rondnia state, western Amazon, Brazil.  

PubMed

This study contributes to knowledge of Anopheles species, including vectors of Plasmodium from the western Brazilian Amazon in Porto Velho, Rondnia State. The sampling area has undergone substantial environmental changes as a consequence of agricultural and hydroelectric projects, which have caused intensive deforestation and favored habitats for some mosquito species. The purpose of this study was to diagnose the occurrence of anopheline species from collections in three locations along an electric-power transmission line. Each locality was sampled three times from 2010 to 2011. The principal adult mosquitoes captured in Shannon trap were Anopheles darlingi, An. triannulatus, An. nuneztovari l.s., An.gilesi and An. costai. In addition, larvae were collected in ground breeding sites for Anopheles braziliensis, An. triannulatus, An. darlingi, An. deaneorum, An. marajoara, An. peryassui, An. nuneztovari l.s. and An. oswaldoi-konderi. Anopheles darlingi was the most common mosquito in the region. We discuss Culicidae systematics, fauna distribution, and aspects of malaria in altered habitats of the western Amazon. PMID:23152319

The Afeio augen-gneiss Suite and the record of the Cariris Velhos Orogeny (1000-960 Ma) within the Riacho do Pontal fold belt, NE Brazil  

NASA Astrophysics Data System (ADS)

Early Tonian (1000-920 Ma) rocks occur within the Transversal Zone of the Borborema Province in Northeast Brazil comprising the 700 km-long sigmoidal Cariris Velhos belt. The Afeio augen-gneiss Suite crops out in the internal zone of the Riacho do Pontal fold belt, about 100 km southwestward of the closest Cariris Velhos occurrence within the Transversal Zone, and has been proposed to represent a continuation of this belt within the Southern subprovince of the Borborema Province. Several plutons included within this unit intrude or are thrust upon metavolcanosedimentary sequences of three different units (Santa Filomena, Paulistana and Morro Branco complexes). The Afeio Suite is composed mostly of calc-alkaline, high-K, peraluminous, high-silica ferroan and magnesian granites. Chondrite-normalized REE patterns are moderate to highly fractionated, with a pronounced negative Eu anomaly. Incompatible element spidergrams show a negative Nb-Ta anomaly, akin to convergence setting (Cordilleran-type) granites. U-Pb zircon data constrain the age of crystallization between 1000 and 960 Ma, thus confirming chrono-correlation with the Cariris Velhos belt. Values of ?Nd(t) between -1.0 and +3.1 and TDM of 1.2-1.5 Ga, similar to other Cariris Velhos occurrences, suggest variable mixing of Tonian juvenile sources with older crustal sources, the latter involving Archean/Paleoproterozoic basement. Although there are currently no reliable geochronological data for the supracrustal sequences of the internal zone, cross-cutting relationships indicate that the Santa Filomena and Morro Branco complexes are older or of similar age to the Afeio Suite, and thus could be related to the Cariris Velhos Orogeny. Based on petrographic, lithogeochemical, geochronological and isotope data, and according to previous models proposed for the Cariris Velhos belt, we interpret the Afeio Suite as the southwestern edge of a continental margin magmatic arc accreted to this portion of West Gondwana during the Early Tonian. Late-Brasiliano dextral displacement through the western branch of the Pernambuco shear zone separated these Cariris Velhos occurrences from its equivalents within the Transversal Zone of the Borborema Province (Recanto-type augen-gneiss of the Alto Paje Terrane).

The early Upper Paleolithic human skeleton from the Abrigo do Lagar Velho (Portugal) and modern human emergence in Iberia  

PubMed Central

The discovery of an early Upper Paleolithic human burial at the Abrigo do Lagar Velho, Portugal, has provided evidence of early modern humans from southern Iberia. The remains, the largely complete skeleton of a ?4-year-old child buried with pierced shell and red ochre, is dated to ca. 24,500 years B.P. The cranium, mandible, dentition, and postcrania present a mosaic of European early modern human and Neandertal features. The temporal bone has an intermediate-sized juxtamastoid eminence. The mandibular mentum osseum and the dental size and proportions, supported by mandibular ramal features, radial tuberosity orientation, and diaphyseal curvature, as well as the pubic proportions align the skeleton with early modern humans. Body proportions, reflected in femorotibial lengths and diaphyseal robusticity plus tibial condylar displacement, as well as mandibular symphyseal retreat and thoracohumeral muscle insertions, align the skeleton with the Neandertals. This morphological mosaic indicates admixture between regional Neandertals and early modern humans dispersing into southern Iberia. It establishes the complexities of the Late Pleistocene emergence of modern humans and refutes strict replacement models of modern human origins. PMID:10377462

Simulating Deforestation and Carbon Loss in Amazonia: Impacts in Brazil's Roraima State from Reconstructing Highway BR-319 (Manaus-Porto Velho).  

PubMed

Reconstruction of Highway BR-319 (Manaus-Porto Velho) would allow for access from the "arc of deforestation" in the southern part of Brazil's Amazon region to vast blocks of forests in central and northern Amazonia. Building roads is known to be a major driver of deforestation, allowing entry of squatters, and other actors. Rather than deforestation along the highway route, here we consider the road's potential for stimulating deforestation in a separate location, approximately 550km north of BR-319's endpoint in Manaus. Reconstructing BR-319 has great potential impact to start a new wave of migration to this remote region. The southern portion of the state of Roraima, the focus of our study, is already connected to Manaus by Highway BR-174. We modeled deforestation in southern Roraima and simulated carbon emissions between 2007 and 2030 under four scenarios. Simulations used the AGROECO model in DINAMICA-EGO software. Two scenarios were considered with reconstruction of BR-319 and two without this road connection. For each of the two possibilities regarding BR-319, simulations were developed for (1) a "conservation" (CONSERV) scenario that assumes the creation of a series of protected areas, and (2) a "business-as-usual" (BAU) scenario that assumes no additional protected areas. Results show that by 2030, with BR-319 rebuilt, deforestation carbon emissions would increase between 19% (CONSERV) and 42% (BAU) over and above those corresponding to no-road scenarios.

STUDY OF THE PREVALENCE OF Capillaria hepatica IN HUMANS AND RODENTS IN AN URBAN AREA OF THE CITY OF PORTO VELHO, RONDNIA, BRAZIL  

PubMed Central

Introduction: Hepatic capillariosis, caused by Capillaria hepatica (Calodium hepaticum) (Bancroft, 1893), Travassos, 1915 (Nematoda, Trichinelloidea, Capillariidae), is a common zoonosis in rodents but is rare in humans. Seventy-two cases in humans have been reported worldwide since the first case was described by MACARTHUR in 192417,27. This study aimed to determine the prevalence of Capillaria hepatica in humans and rodents in an urban area of Porto Velho, the capital of Rondnia, in Brazil. Methods: After conducting a census of the area, 490 residents were randomly selected, and, after signing a term of consent, provided blood samples that were screened for anti-Capillaria hepatica antibodies. Simultaneously, rats were captured to assess the prevalence of this parasite in rodents by histopathological examination in liver sections. Results: A prevalence of 1.8% was found among residents who had specific antibodies at a dilution of 1:150, indicating exposure to parasite eggs; 0.8% of the subjects also had positive titers at a dilution of 1:400, indicating true infection. The prevalence in rats was 2%. Conclusions: The prevalence of infection with this parasite among humans and rats was low. While the prevalence encountered among humans was within the limits reported in the literature, the prevalence among rodents was much lower. PMID:25651325

Problemas de nervos: a multivocal symbol of distress for Portuguese immigrants.  

PubMed

This article outlines research on a previous unstudied form of suffering specific to the Portugese immigrant community: problemas de nervos. Thirty-two Portuguese immigrant women (in Waterloo, ON and Boston, MA) were interviewed and each completed a questionnaire. Cluster analysis demonstrated that problemas de nervos has many meanings. The study profiled symptoms, causes and therapies associated with four variations of this culture-specific form of distress: "mal da cabeca" meaning problems with/in the head (e.g., lack of control, visions); " aflio" meaning affliction (e.g., nervous attacks, heart problems); immigration stress (causing sleep disturbances); and, conflicts with others (resulting in pressure within the body). None of the symptom clusters reported matched criteria for a DSM-IV-TR diagnosis, suggesting that problemas de nervos represents an idiomatic rather than universal expression of distress.

Parylene supported 20um*20um uncooled thermoelectric infrared detector with high fill factor  

NASA Astrophysics Data System (ADS)

Presented is a novel design for an uncooled surface-micromachined thermoelectric (TE) infrared (IR) detector. The detector features a P-doped polysilicon/Nichrome (Cr20-Ni80) thermocouple, which is embedded into a thin layer of Parylene-N to provide structural support. The low thermal conductivity (~0.1W/m.K), chemical resistance, and ease of deposition/patterning of Parylene-N make it an excellent choice of material for use in MEMS thermal detectors. This detector also features an umbrella-like IR absorber composed of a three layer stack of NiCr/SiN/NiCr to optimize IR absorption. The total device area is 20 um * 20 um per pixel with an absorber area of ~19 um * 19 um resulting in a fill factor of 90%. At room temperature, a DC responsivity of ~170V/W with a rise time of less than 8 ms is measured from the fabricated devices in vacuum when viewing a 500K blackbody without any concentrating optics. The dominant source of noise in thermoelectric IR detectors is typically Johnson noise when the detectors are operating in an open circuit condition. The fabricated detectors have resistances about 85KOhm which results in Johnson noise of about 38nV/Hz^0.5. The D* is calculated to be 9 * 106 cm*Hz0.5/ W. Preliminary finite element analysis indicates that the thermal conduction from the hot junction to the substrate through the TE wires is dominant ( GTE >> Gparylene) considering the fabricated dimensions of the parylene film and the TE wires. Thus, by further reducing the size of the TE wires, GTE can be decreased and hence, responsivity can be improved while the parylene film sustains the structural integrity of the cell.

Extinctions at 7um and 15um from the ISOGAL survey  

E-print Network

The extinction laws at 7um and 15um are derived for more than 120 sightlines in the inner Galactic plane based on the ISOGAL survey data and the near-infrared data from DENIS and 2MASS. The tracers are the ISOGAL point sources with [7]-[15]<0.4 which are RGB tip stars or early AGB stars with moderate mass loss. They have well-defined intrinsic color indices (J-Ks)_0, (Ks-[7])_0 and (Ks-[15])_0. By a linear fitting of the observed color indices Ks-[7] and Ks-[15] to the observed J-Ks, we obtain the ratio between the E(Ks-[7]) and E(Ks-[15]) color excesses and E(J-Ks). We infer the selective extinctions at 7 and 15um in terms of the near-infrared extinction in the Ks band. The distribution of the derived extinctions around 7 micron (A_7) is well represented by a Gaussian function, with the peak at about 0.47A_Ks and ranging from 0.33 to 0.55A_Ks (using the near-infrared extinctions of Rieke & Lebovsky 1985). There is some evidence that A_7/A_Ks may vary significantly depending on the line of sight. The derived selective extinction at 15um suffers uncertainty mainly from the dispersion in the intrinsic color index (Ks-[15])_0 which is affected by dust emission from mass-losing AGB stars. The peak value of A_15 is around 0.40A_Ks.

Uh and um revisited: are they interjections for signaling delay?  

PubMed

Clark and Fox Tree (2002) have presented empirical evidence, based primarily on the London-Lund corpus (LL; Svartvik & Quirk, 1980), that the fillers uh and um are conventional English words that signal a speaker's intention to initiate a minor and a major delay, respectively. We present here empirical analyses of uh and um and of silent pauses (delays) immediately following them in six media interviews of Hillary Clinton. Our evidence indicates that uh and um cannot serve as signals of upcoming delay, let alone signal it differentially: In most cases, both uh and um were not followed by a silent pause, that is, there was no delay at all; the silent pauses that did occur after um were too short to be counted as major delays; finally, the distributions of durations of silent pauses after uh and um were almost entirely overlapping and could therefore not have served as reliable predictors for a listener. The discrepancies between Clark and Fox Tree's findings and ours are largely a consequence of the fact that their LL analyses reflect the perceptions of professional coders, whereas our data were analyzed by means of acoustic measurements with the PRAAT software (www.praat.org). A comparison of our findings with those of O'Connell, Kowal, and Ageneau (2005) did not corroborate the hypothesis of Clark and Fox Tree that uh and um are interjections: Fillers occurred typically in initial, interjections in medial positions; fillers did not constitute an integral turn by themselves, whereas interjections did; fillers never initiated cited speech, whereas interjections did; and fillers did not signal emotion, whereas interjections did. Clark and Fox Tree's analyses were embedded within a theory of ideal delivery that we find inappropriate for the explication of these phenomena. PMID:16341914

Time Delay Between Images of the Lensed Quasar UM673  

NASA Astrophysics Data System (ADS)

We study brightness variations in the double lensed quasar UM673 (Q0142-100) with the aim of measuring the time delay between its two images. Methods.. We analyzed the V, R and I-band light curves of the A and B images of UM673, which cover ten observational seasons from August 2001 to November 2010. We also analyzed the time evolution of the difference in magnitudes (flux ratio) between images A and B of UM673 over more than ten years. We find that the quasar exhibits both short-term (with an amplitude of ~ 0.1 mag in the R band) and long-term (with an amplitude of ~ 0.3 mag) variability on timescales of about several months and several years, respectively. These brightness variations are used to constrain the time delay between the images of UM673. From a cross-correlation analysis of the A and B quasar light curves and an error analysis we measure a mean time delay of 89 days with an rms error of 11 days.

The International Space Station Urine Monitoring System (UMS)  

NASA Technical Reports Server (NTRS)

A device capable of making in-flight volume measurements of single void urine samples, the Urine Monitoring System (UMS), was developed and flown on seven U.S. Space Shuttle missions. This device provided volume data for each urine void from multiple crewmembers and allowed samples of each to be taken and returned to Earth for post-flight analysis. There were a number of design flaws in the original instrument including the presence of liquid carry-over producing invalid "actual" micturition volumes and cross-contamination between successive users from residual urine in "dead" spots". Additionally, high or low volume voids could not be accurately measured, the on-orbit calibration and nominal use sequence was time intensive, and the unit had to be returned and disassembled to retrieve the volume data. These problems have been resolved in a new version, the International Space Station (ISS) UMS, that has been designed to provide real-time in-flight volume data with accuracy and precision equivalent to measurements made on Earth and the ability to provide urine samples that are unadulterated by the device. Originally conceived to be interfaced with a U.S.-built Waste Collection System (WCS), the unit now has been modified to interface with the Russian-supplied Sanitary Hygiene Device (ASY). The ISS UMS provides significant advantages over the current method of collecting urine samples into Urine Collection Devices (UCDs), from which samples are removed and returned to Earth for analyses. A significant future advantage of the UMS is that it can provide an interface to analytical instrumentation that will allow real-time measurement of urine bioanalytes allowing monitoring of crewmember health status during flight and the ability to provide medical interventions based on the results of these measurements. Currently, the ISS UMS is scheduled to launch along with Node-3 on STS-130 (20A) in December 2009. UMS will be installed and scientific/functional verification completed prior to placing the instrument into operation. Samples collected during the verification sequence will be returned for analyses on STS-131 (19A) currently scheduled for launch in March 2010. The presence of a UMS on ISS will provide the capability to conduct additional collaborative human life science investigations among the ISS International Partners.

Time delay between images of the lensed quasar UM673  

NASA Astrophysics Data System (ADS)

Aims: We study brightness variations in the double lensed quasar UM673 (Q0142-100) with the aim of measuring the time delay between its two images. Methods: We combined our previously published observational data of UM673 obtained during the 2003-2005 seasons at the Maidanak Observatory with archival and recently observed Maidanak and CTIO UM673 data. We analyzed the V, R and I-band light curves of the A and B images of UM673, which cover ten observational seasons from August 2001 to November 2010. We also analyzed the time evolution of the difference in magnitudes (flux ratio) between images A and B of UM673 over more than ten years. Results: We find that the quasar exhibits both short-term (with an amplitude of ~0.1 mag in the R band) and long-term (with an amplitude of ~0.3 mag) variability on timescales of about several months and several years, respectively. These brightness variations are used to constrain the time delay between the images of UM673. From a cross-correlation analysis of the A and B quasar light curves and an error analysis we measure a mean time delay of 89 days with an rms error of 11 days. Given the input time delay of 88 days, the most probable value of the delay that can be recovered from light curves with the same statistical properties as the observed R-band light curves of UM673, is 95-16+5-29+14 days (68% and 95% confidence intervals). Analysis of the V - I color variations and the V, R and I-band magnitude differences of the quasar images does not show clear evidence for microlensing variations between 1998 and 2010.

The bright 175um knots of the Andromeda Galaxy  

E-print Network

Discrete far-infrared (FIR) sources of M31 are identified in the ISO 175um map and characterized via their FIR colours, luminosities and masses. With a mean size of 800pc, they probably represent several clouds in chance projection or giant cloud complexes. The 175um data point provides crucial information in addition to the IRAS 60 and 100um data: At least two modified Planck curves with temperatures of about 40K and 15-21K are necessary to fit the SEDs of the knots. We distinguish between three types of knots - cold, medium, warm - in order to recognize trends. Comparisons with radio and optical tracers show that - statistically - the cold knots can be identified well with CO and HI radio sources and thus might represent mainly molecular cloud complexes. The warm knots coincide with known HII regions and supernova remnants. The medium knots might contain a balanced mixture of molecular clouds and HII regions. The cold knots have a considerable luminosity and their discovery raises the question of hidden star formation. Though the optically dark dust lanes in M31 generally match the FIR ring, surprisingly we do not find a convincing coincidence of our knots with individual dark clouds which might therefore show mainly foreground dust features. The ratio of FIR luminosity to dust mass, L/M, is used to measure the energy content of the dust. The knots have a clear L/M excess over the rest of M31, providing evidence that they are powered by star formation in addition to the interstellar radiation field. The L/M ratio of the warm knots is comparable to that of Galactic HII regions like M42 or NGC2024, while that of the cold knots still reaches values like in the average Orion complex. Thus both the warm and the cold knots are interpreted as containing large cloud complexes with considerable ongoing star formation.

Why Um Helps Auditory Word Recognition: The Temporal Delay Hypothesis  

PubMed Central

Several studies suggest that speech understanding can sometimes benefit from the presence of filled pauses (uh, um, and the like), and that words following such filled pauses are recognised more quickly. Three experiments examined whether this is because filled pauses serve to delay the onset of upcoming words and these delays facilitate auditory word recognition, or whether the fillers themselves serve to signal upcoming delays in a way which informs listeners' reactions. Participants viewed pairs of images on a computer screen, and followed recorded instructions to press buttons corresponding to either an easy (unmanipulated, with a high-frequency name) or a difficult (visually blurred, low-frequency) image. In all three experiments, participants were faster to respond to easy images. In 50% of trials in each experiment, the name of the image was directly preceded by a delay; in the remaining trials an equivalent delay was included earlier in the instruction. Participants were quicker to respond when a name was directly preceded by a delay, regardless of whether this delay was filled with a spoken um, was silent, or contained an artificial tone. This effect did not interact with the effect of image difficulty, nor did it change over the course of each experiment. Taken together, our consistent finding that delays of any kind help word recognition indicates that natural delays such as fillers need not be seen as signals to explain the benefits they have to listeners' ability to recognise and respond to the words which follow them.

STAR CLUSTER COMPLEXES AND THE HOST GALAXY IN THREE H II GALAXIES: Mrk 36, UM 408, AND UM 461  

SciTech Connect

We present a stellar population study of three H II galaxies (Mrk 36, UM 408, and UM 461) based on the analysis of new ground-based high-resolution near-infrared J, H, and K{sub p} broadband and Br{gamma} narrowband images obtained with Gemini/NIRI. We identify and determine the relative ages and masses of the elementary star clusters and/or star cluster complexes of the starburst regions in each of these galaxies by comparing the colors with evolutionary synthesis models that include the contribution of stellar continuum, nebular continuum, and emission lines. We found that the current star cluster formation efficiency in our sample of low-luminosity H II galaxies is {approx}10%. Therefore, most of the recent star formation is not in massive clusters. Our findings seem to indicate that the star formation mode in our sample of galaxies is clumpy, and that these complexes are formed by a few massive star clusters with masses {approx}>10{sup 4} M{sub Sun }. The age distribution of these star cluster complexes shows that the current burst started recently and likely simultaneously over short timescales in their host galaxies, triggered by some internal mechanism. Finally, the fraction of the total cluster mass with respect to the low surface brightness (or host galaxy) mass, considering our complete range in ages, is less than 1%.

Recovery Act: Novel Kerf-Free PV Wafering that provides a low-cost approach to generate wafers from 150um to 50um in thickness  

SciTech Connect

The technical paper summarizes the project work conducted in the development of Kerf-Free silicon wafering equipment for silicon solar wafering. This new PolyMax technology uses a two step process of implantation and cleaving to exfoliate 50um to 120um wafers with thicknesses ranging from 50um to 120um from a 125mm or 156mm pseudo-squared silicon ingot. No kerf is generated using this method of wafering. This method of wafering contrasts with the current method of making silicon solar wafers using the industry standard wire saw equipment. The report summarizes the activity conducted by Silicon Genesis Corporation in working to develop this technology further and to define the roadmap specifications for the first commercial proto-type equipment for high volume solar wafer manufacturing using the PolyMax technology.

Spatially Extended [P II]1.188um and [Fe II]1.257um Emission Lines Observed with OAO/ISLE  

E-print Network

We present J-band long-slit spectroscopic observation of NGC 1068 classified as a Seyfert 2 galaxy. J-band observations with OAO/ISLE provide clear detection of spatially extended [Fe II]1.257um and [P II]1.188um lines. We found that [Fe II]1.257um/[P II]1.188um increases with distance from a central continuum peak. Observed line ratios around the nucleus (continuum peak) are consistent with a typical value expected from photoionization models, while the ratios at 3" - 4" (210-280 pc) east and west of the nucleus are slightly higher than this. In the off nucleus region of NGC 1068 we also found a possible association between [Fe II]1.257um/[P II]1.188um and the radio continuum. This suggests a mild contribution of shock ionization induced by a radio jet outside nucleus while photoionization by the central energy source is dominant near the nucleus.

M UM AX: A new high-performance micromagnetic simulation tool  

NASA Astrophysics Data System (ADS)

We present M UM AX, a general-purpose micromagnetic simulation tool running on graphical processing units (GPUs). M UM AX is designed for high-performance computations and specifically targets large simulations. In that case speedups of over a factor 100 can be obtained compared to the CPU-based OOMMF program developed at NIST. M UM AX aims to be general and broadly applicable. It solves the classical Landau-Lifshitz equation taking into account the magnetostatic, exchange and anisotropy interactions, thermal effects and spin-transfer torque. Periodic boundary conditions can optionally be imposed. A spatial discretization using finite differences in two or three dimensions can be employed. M UM AX is publicly available as open-source software. It can thus be freely used and extended by community. Due to its high computational performance, M UM AX should open up the possibility of running extensive simulations that would be nearly inaccessible with typical CPU-based simulators.

New near-infrared observations and lens-model constraints for UM673  

NASA Astrophysics Data System (ADS)

Aims: We performed a detailed photometric analysis of the lensed system UM673 (Q0142-100) and an analysis of the tentative lens models. Methods: High-resolution adaptive optics images of UM673 taken with the Subaru telescope in the H band were examined. We also analysed the J, H and K-band observational data of UM673 obtained with the 1.3 m telescope at the CTIO observatory. Results: We present photometry of quasar components A and B of UM673, the lens, and the nearby bright galaxy using H-band observational data obtained with the Subaru telescope. Based on the CTIO observations of UM673, we also present J- and H-band photometry and estimates of the J, H and K-band flux ratios between the two UM673 components in recent epochs. The near-infrared fluxes of the A and B components of UM673 and their published optical fluxes are analysed to measure extinction properties of the lensing galaxy. We estimate the extinction-corrected flux ratio between components A and B to be about 2.14 mag. We discuss lens models for the UM673 system constrained with the positions of the UM673 components, their flux ratio, and the previously measured time delay. Based in part on data collected at Subaru Telescope, which is operated by the National Astronomical Observatory of Japan.The final reduced Subaru images presented in Figs. 1 and 2 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/566/A36

Das Mrchen vom Zauberer im weien Kittel: Mythen um berhmte Experimente und Experimentatoren  

NASA Astrophysics Data System (ADS)

Um berhmte Experimentatoren und Experimente ranken sich ebenso Mythen wie um geniale Theoretiker. Sie sind in populrwissenschaftlichen Bchern, Lehrbchern und sogar in wissenschaftshistorischen Texten verbreitet. Die durch die Aufklrung etablierte Kultur des eleganten Schauexperiments vermittelt ein schiefes Bild vom mhsamen Weg vieler Experimentatoren zum dargestellten Ergebnis. Auch der Mythos des einsamen, genialen Experimentators ohne Helfer widerspricht dem historischen Befund. Gleiches gilt fr das experimentum crucis, das eine Theorie als entscheidendes Experiment belegen soll. Die historische Forschung zeigt, dass es eine lange, eigenstndige Tradition der experimentellen und instrumentellen Arbeit gibt.

MetUM-GOML: a near-globally coupled atmosphere-ocean-mixed-layer model  

NASA Astrophysics Data System (ADS)

Well-resolved air-sea interactions are simulated in a new Ocean Mixed Layer coupled configuration of the Met Office Unified Model (MetUM-GOML), comprising the MetUM coupled to the Multi-Column K Profile Parametrization ocean (MC-KPP). This is the first globally coupled system which provides a vertically resolved, high near-surface resolution ocean at comparable computational cost to running in atmosphere-only mode. As well as being computationally inexpensive, this modelling framework is adaptable - the independent MC-KPP columns can be applied selectively in space and time - and controllable - by using temperature and salinity corrections the model can be constrained to any ocean state. The framework provides a powerful research tool for process-based studies of the impact of air-sea interactions in the global climate system. MetUM simulations have been performed which separate the impact of introducing interannual variability in sea surface temperatures (SSTs) from the impact of having atmosphere-ocean feedbacks. The representation of key aspects of tropical and extra-tropical variability are used to assess the performance of these simulations. Coupling the MetUM to MC-KPP is shown, for example, to reduce tropical precipitation biases, improve the propagation of, and spectral power associated with, the Madden-Julian Oscillation and produce closer-to-observed patterns of springtime blocking activity over the Euro-Atlantic region.

The UM-Dearborn Observatory: Variable-object Research from an Urban Site  

NASA Astrophysics Data System (ADS)

Since its construction in 2007, the UM-Dearborn Observatory has provided a valuable educational tool both for students at UM-Dearborn and our neighbor-institution the Henry Ford Community College, and for the public at-large. We have recently (Jan 2014) added a systematic long-term research program with our 0.4m main telescope, to photometrically monitor a number of bright variable objects, including X-ray binaries and chemically-peculiar metal-poor stars over long timescales. We ultimately envision assembling a photometric database of (at least) four-color photometry over years-decades (i.e., many hundreds of orbital timescales for close binaries), with the preponderance of datapoints taken by undergraduates. To conduct this program, we have had to overcome a number of site challenges, the solutions of which will be useful to many programs using small telescopes at urban sites. The 0.4m telescope lies on a shared building within UM-Dearborn's main Fairlane campus - i.e., is about 20 meters above sea level, near several sources of water vapor (including an active steam vent less than 15 meters away), experiences significant mechanical vibrations from other building functions, and lies about 6 miles from central Detroit, well within the Detroit-Ann Arbor conurbation. Observing conditions are thus highly variable, with 5 arcsecond seeing typical and significant transparency variations observed even during a clear night. Nevertheless, we are now able to make scientifically useful observations in a semi-automatic way, to which our chosen scientific niche is well-suited. We present here our solutions to these challenges, along with initial results from our ongoing monitoring program.

Wissenschaft, die unsere Kultur verndert. Tiefenschichten des Streits um die Evolutionstheorie  

NASA Astrophysics Data System (ADS)

Die Evolutionstheorie ist eine der erfolgreichsten wissenschaftlichen Theorien. Sie erlaubt es, unsere Herkunft zu verstehen und riskante Merkmale gerade der menschlichen Spezies zu begreifen. Zugleich ist die Evolutionstheorie eine der umstrittensten Theorien. Das liegt nicht an ihrer empirischen Tragfhigkeit, sondern an ihrem Gegenstand. Sie handelt nmlich nicht nur - wie Hunderte andere wissenschaftliche Theorien - von der "Welt da drauen, sondern vor allem auch von uns selbst und von unserem Platz in dieser Welt. Den einen gilt sie obendrein als berwinderin religisen Aberglaubens, den anderen als neuer Zugang zu Gott und seinem Wirken in der Welt. Ferner sehen die einen in der Evolution eine unbezweifelbare Tatsache gleich der Schwerkraft oder dem Holocaust, die anderen aber eine - noch oder dauerhaft - unbewiesene Hypothese oder gar eine falsche Schpfungslehre. Und whrend die meisten Streitfragen solcher Art nach wechselseitig akzeptierten Regeln normaler Wissenschaft geklrt werden, wird bei der Frage nach dem Woher unserer Spezies und Kultur die intellektuelle Zustndigkeit von Wissenschaft mitunter berhaupt bezweifelt. Anscheinend geht es schon um recht tiefe Schichten unserer Kultur und nicht nur der wissenschaftlichen, wenn - wie seit 150 Jahren - um die Evolutionstheorie gestritten wird. Wie sehen diese Schichten aus?

MiR-222 Targeted PUMA to Improve Sensitization of UM1 Cells to Cisplatin  

PubMed Central

microRNAs have been shown to play critical roles in regulating the chemosensitivity of cancer cells. As a member of the oncogenic miRNAs (oncomiRs), miR-222 has been reported to drive the oncogenesis of many types of malignancies. However, little is known concerning the specific role of miR-222 in human oral squamous cell carcinoma (OSCC). The present study explored the role and mechanism of miR-222 in increasing the expression of p53 up-regulated modulator of apoptosis (PUMA) and enhancing the sensitivity of OSCC to cisplatin (CDDP). Results showed that antisense (As)-miR-222 inhibits the expression of miR-222. In contrast, PUMA was dramaticallyup-regulated. IC50 values were significantly decreased in cells treated with As-miR-222 combined with CDDP, to a greater extent than in cells treated with CDDP alone. Furthermore, As-miR-222 enhanced apoptosis and inhibited the invasiveness of UM1 cells. Analysis of the above data suggested that, in UM1 cells, there might be a regulatory loop between miR-222 and PUMA, and that miR-222 inhibition increased the chemosensitivity to CDDP. These findings demonstrated that down-regulation of miR-222 could enhance the chemosensitivity of human OSCC cells to CDDP, and that the combination of As-miR-222 and CDDP could be an effective therapeutic strategy by boosting the expression of PUMA for controlling the growth of OSCC.

We have determined the luminosity function of 250um-selected galaxies detected in the ~14 sq.deg science demonstration region of the Herschel-ATLAS project out to a redshift of z=0.5. Our findings very clearly show that the luminosity function evolves steadily out to this redshift. By selecting a sub-group of sources within a fixed luminosity interval where incompleteness effects are minimal, we have measured a smooth increase in the comoving 250um luminosity density out to z=0.2 where it is 3.6+1.4-0.9 times higher than the local value.

Comparative genomic analysis of Mycobacterium iranicum UM_TJL against representative mycobacterial species suggests its environmental origin  

PubMed Central

Mycobacterium iranicum is a newly reported mycobacterial species. We present the first comparative study of M. iranicum UM_TJL and other mycobacteria. We found M. iranicum to have a close genetic association with environmental mycobacteria infrequently associated with human infections. Nonetheless, UM_TJL is also equipped with many virulence genes (some of which appear to be the consequence of transduction-related gene transfer) that have been identified in established human pathogens. Taken all together, our data suggest that M. iranicum is an environmental bacterium adapted for pathogenicity in the human host. This comparative study provides important clues and forms the basis for future functional studies on this mycobacterium. PMID:25417557

UM 625 Revisited: Multiwavelength Study of a Seyfert 1 Galaxy with a Low-mass Black Hole  

NASA Astrophysics Data System (ADS)

UM 625, previously identified as a narrow-line active galactic nucleus (AGN), actually exhibits broad H? and H? lines whose width and luminosity indicate a low black hole (BH) mass of 1.6 106 M ?. We present a detailed multiwavelength study of the nuclear and host galaxy properties of UM 625. Analysis of Chandra and XMM-Newton observations suggests that this system contains a heavily absorbed and intrinsically X-ray weak (?ox = -1.72) nucleus. Although not strong enough to qualify as radio loud, UM 625 does belong to a minority of low-mass AGNs detected in the radio. The broadband spectral energy distribution constrains the bolometric luminosity to L bol ? (0.5-3) 1043 erg s-1 and L bol/L Edd ? 0.02-0.15. A comprehensive analysis of Sloan Digital Sky Survey and Hubble Space Telescope images shows that UM 625 is a nearly face-on S0 galaxy with a prominent, relatively blue pseudobulge (Srsic index n = 1.60) that accounts for ~60% of the total light in the R band. The extended disk is featureless, but the central ~150-400 pc contains a conspicuous semi-ring of bright, blue star-forming knots, whose integrated ultraviolet luminosity suggests a star formation rate of ~0.3 M ? yr-1. The mass of the central BH roughly agrees with the value predicted from its bulge velocity dispersion but is significantly lower than that expected from its bulge luminosity.

Estimation of broadband emissivity (8-12 um) from ASTER data by using RM-NN.  

PubMed

Land surface window emissivity is a key parameter for estimating the longwave radiative budget. The combined radiative transfer model (RM) with neural network (NN) algorithm is utilized to directly estimate the window (8-12 um) emissivity from the brightness temperature of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) with 90 m spatial resolution. Although the estimation accuracy is very high when the broadband emissivity is estimated from AST05 (ASTER Standard Data Product) by using regression method, the accuracy of AST05 is about 0.015 for 86 spectra which is determined by the atmosphere correction for ASTER 1B data. The MODTRAN 4 is used to simulate the process of radiance transfer, and the broadband emissivity is directly estimated from the brightness temperature of ASTER 1B data at satellite. The comparison analysis indicates that the RM-NN is more competent to estimate broadband emissivity than other method when the brightness temperatures of band 11, 12, 13, 14 are made as input nodes of dynamic neural network. The estimation average accuracy is about 0.009, and the estimation results are not sensitive to instrument noise. The RM-NN is applied to extract broadband emissivity from an image of ASTER 1B data in China, and the comparison against a classification based multiple bands with 15 m spatial resolution shows that the estimation results from RM-NN are very good.

Project UM-HAUL: A self-unloading reusable lunar lander  

NASA Technical Reports Server (NTRS)

The establishment of a lunar base is technologically and financially challenging. Given the necessary resources and political support, it can be done. In addition to the geopolitical obstacles, however, there are logistical problems involved in establishing such bases that can only be overcome with the acquisition of a significant transportation and communications network in the Earth-Moon spatial region. Considering the significant number of payloads that will be required in this process, the mass-specific cost of launching these payloads, and the added risk and cost of human presence in space, it is clearly desirable to automate major parts of such an operation. One very costly and time-consuming factor in this picture is the delivery of payloads to the Moon. Foreseeable payloads would include atmospheric modules, inflatable habitat kits, energy and oxygen plant elements, ground vehicles, laboratory modules, crew supplies, etc. The duration of high-risk human presence on the Moon could be greatly reduced if all such payloads were delivered to the prospective base site in advance of crew arrival. In this view, the idea of a 'Self-Unloading Reusable Lunar Lander' (SURLL) arises naturally. The general scenario depicts the lander being brought to low lunar orbit (LLO) from Earth atop a generic Orbital Transfer Vehicle (OTV). From LLO, the lander shuttles payloads down to the lunar surface, where, by means of some resident, detachable unloading device, it deploys the payloads and returns to orbit. The general goal is for the system to perform with maximum payload capability, automation, and reliability, while also minimizing environmental hazards, servicing needs, and mission costs. Our response to this demand is UM-HAUL, or the UnManned Heavy pAyload Unloader and Lander. The complete study includes a system description, along with a preliminary cost analysis and a design status assessment.

Phenotypic characterization, karyotype analysis and in vitro tamoxifen sensitivity of new ER-negative vulvar carcinoma cell lines, UM-SCV-1A and UM-SCV-1B.  

PubMed

Two cell lines (University of Michigan squamous carcinoma of the vulva UM-SCV-1A and UM-SCV-1B) were established from the primary tumor and a malignant pleural effusion of a 62-year-old woman. Both tumor specimens grew vigorously in vitro and could be passaged after only 14 and 10 days in culture, respectively. Both cell lines undergo 3 population doublings in 4 days, reaching saturation densities of 5 x 10(5) cells/cm2, and have been carried through more than 30 in vitro passages. In nude mice the cultured cells initially formed tumors but these regressed 2-3 weeks after inoculation. The regressing mouse tumors consisted of poorly differentiated squamous carcinoma surrounded by an inflammatory lymphoid infiltrate. The UM-SCV-1 cell lines express membrane antigens typically displayed by squamous-cell carcinomas. These include the HLA class-1 light chain beta 2-microglobulin, pemphigus, pemphigoid, and the alpha 6 beta 4 integrin defined by the UM-A9 monoclonal antibody (MAb). In contrast to the A431 vulvar carcinoma, these tumor lines do not have amplified expression of the epidermal growth factor (EGF) receptor. Although tissue from the primary tumor contained low levels of estrogen receptor activity, no receptor activity was detected in the cell lines. Nevertheless, both lines were sensitive to growth inhibition by tamoxifen. This effect was not reversible by estradiol, indicating an estrogen-receptor-independent mechanism. The tumors were both hypotetraploid, contained the same chromosome rearrangements and had stable karyotypes in vitro. Each contained inv(1)(p36.3q32.1), del(4)(q12), dic(4;11)(q12;p11.2), i(5p), der(6)t(3;6)(q25.1;p21.1), several rearrangements involving chromosomes 8 and 14, + i(13), i(18p), a dicentric t(11;19), and 2 or 3 unidentified markers. Since the karyotypes of both tumors were the same, no major karyotypic change was associated with metastatic spread. These paired primary and metastatic SCC lines from an unusually aggressive vulvar carcinoma provide an in vitro model for analysis of the biological basis of this tumor's behavior. PMID:2335395

Coupled fiber taper extraction of 1.53 um photoluminescence from erbium doped silicon nitride photonic crystal cavities  

E-print Network

Optical fiber tapers are used to collect photoluminescence emission at ~1.5 um from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. Photoluminescence collection via fiber taper is enhanced 2.5 times relative to free space, with a total taper collection efficiency of 53%. By varying the fiber taper offset from the cavity, a broad tuning range of coupling strength is obtained. This material system combined with fiber taper collection is promising for building on-chip optical amplifiers.

Silver and silver-bearing minerals at the Um Samiuki volcanogenic massive sulphide deposit, Eastern Desert, Egypt  

NASA Astrophysics Data System (ADS)

The Um Samiuki Zn Cu Pb Ag mineralisation, south Eastern Desert, Egypt is hosted by felsic volcanic rocks which form part of the 712-Ma-old, east-west-trending Shadli Volcanic Belt. Two major occurrences of massive sulphides are present at the top of rhyolitic breccia in the Western and Eastern mine areas. In each occurrence, a bornite-bearing zone is overlain by a pyrite-chalcopyrite-bearing zone and underlain by a disseminated, Cu-depleted zone. In the massive sulphide ore, sphalerite, chalcopyrite, pyrite, galena, bornite and tetrahedrite tennantite are major minerals, whereas arsenopyrite, pyrrhotite, molybdenite and magnetite are accessory phases. Covellite and digenite are common secondary minerals. Bornite, tetrahedrite tennantite and covellite contain high amounts of silver (averages of 1.97, 1.39 and 1.82 wt% respectively). Based on mineralogical balance calculations, bornite and covellite accommodate 80% of silver in the Um Samiuki deposit. Ag was incorporated in the crystal structure of the early-crystallised copper sulphides and sulphosalts and silver minerals. The temperature, sequential precipitation of the fluids and the structure of the crystallising phases control the distribution of silver. Post-depositional deformation and metamorphic processes caused liberation, remobilisation and redeposition of silver within the massive sulphides.

Embora os Parmetros Curriculares Nacionais do Ensino Mdio (PCN-EM) e as Orientaiacute;es Complementares aos Parmetros (PCN+) apontem a importncia de uma abordagem significativa de conceitos relacionados Astronomia nas aulas de Fsica, muitos estudantes terminam o Ensino Mdio (EM) sem compreender a razo de certos acontecimentos de origem celeste, ainda que estes faam parte de seu cotidiano e sejam alvos da curiosidade natural dos jovens. Da observao dessa curiosidade em alunos de uma escola pblica paulista, na cidade de Suzano, surgiu o interesse em investigar os conhecimentos bsicos em Astronomia dos alunos do Ensino Mdio desta escola, constituindo-se este como principal objetivo desta pesquisa. Para tanto foi elaborado um questionrio de mltipla escolha aplicado inicialmente a 34 alunos do primeiro ano e, posteriormente, a mais 310, distribudos entre as trs sries do Ensino Mdio dos perodos matutino e noturno. Dessa forma, observou-se que 73,9% dos estudantes identificaram o Sol como sendo uma estrela, 67,1% mostraram compreender a sucesso entre dia e noite e 52,3% relacionaram o Big Bang origem do Universo. Em contrapartida, apenas 34,5% relacionaram as estaes do ano inclinao do eixo de rotao da Terra, 21,3% indicaram a influncia gravitacional simultnea da Lua e do Sol como responsvel pelo fenmeno das mars, 24,5% indicaram corretamente quais so os objetos celestes mais prximos da Terra, 36,1% identificaram ano-luz como uma medida de distncia e 34,2% reconheceram as estrelas cadentes como meteoros, evidenciando-se assim o pequeno discernimento dos estudantes quanto aos fenmenos e termos astronmicos do cotidiano. Alm disso, foram comparadas as respostas de alun! os de diferentes sries e perodos, observando-se, dentre ou tras coi sas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tpicos relacionados astronomia no Ensino Mdio no tem contribudo de forma significativa para uma maior compreenso dos fenmenos e conceitos.

Banded iron formations of Um Nar, Eastern Desert of Egypt: P-T-X conditions of metamorphism and tectonic implications  

NASA Astrophysics Data System (ADS)

Banded iron formations (BIF) in Um Nar, central eastern desert of Egypt, occur intercalated with schists of volcaniclastic and epiclastic origins within "ophiolitic-island arc rocks" of the Arabo-Nubian Shield. The BIF and its host rocks were affected by folding, thrusting, and regional metamorphism during the Pan-African Orogeny resulting in the development of north-verging overturned folds and E-W striking, S-dipping thrusts. Following the intrusion of granitoids, the entire sequence was refolded into south-plunging folds with NW-SE trending fold axes. Peak mineral assemblages of hornblende + plagioclase, and garnet + biotite + plagioclase + quartz in the host rocks, and andradite-rich garnet + epidote + hematite + magnetite + quartz in the BIF indicate metamorphism under epidote amphibolite facies conditions. Using the multiequilibrium approach of Thermocalc, and conventional thermobarometry, peak P-T conditions of metamorphism are estimated at 520 30 C, 5 2 kbar. Fluids attending peak conditions in the oxide facies layers of the BIF were characterized by XCO2 ~ 0.03 and log fO2 ~ - 40. Textural and mineral chemical criteria suggest that, following peak conditions, the rocks underwent a stage of near-isobaric cooling or cooling and compression characteristic of a counter-clockwise P-T path.

Jets and Outflows from Young Stellar Objects in the Carina Nebula Observed in [Fe II] 1.64 um  

NASA Astrophysics Data System (ADS)

We present [Fe II] 1.64 um imaging observations for jets and outflows from young stellar objects (YSOs) over the northern part (~24'x45') of the Carina Nebula, a massive star forming region. The observations were performed with IRIS2 of Anglo-Autralian Telescope and the seeing was ~1.5". Several jets and outflows features are detected at eight different regions, and named as forbidden emission line regions (FELRs). One new candidate for Herbig-Haro Object is identified comparing our [Fe II] images to H_alpha images of Hubble Space Telescope. FELRs have knotty or longish shapes, and distribute around the triangular area formed by three star clusters Tr 14, Tr 15, and Tr 16, which contain many massive stars. The detection rate of FELRs against previously identified YSOs is 1.4 %. We estimate the outflow rate from the [Fe II] flux based on some assumptions. The jet-driving objects are identified for three FELRs (FELR-2, -4, and -7), for which we study the relations between the outflow rate and the YSO physical parameters from the radiative transfer model fitting. The ratios of the outflow rate over the disk accretion rate are consistent for FELR-4 and -7 with the previously reported values, while it is higher for FELR-2. The masses of jet-driving objects are low or intermediate, and they are not likely to become massive stars (> 8 Ms). Other YSO physical parameters, such as luminosity and age, show reasonable relations or trends.

Calcareous benthonic foraminifera across the Cretaceous/Paleocene transition of Gebel Um El-Ghanayem, Kharga Oasis, Egypt  

NASA Astrophysics Data System (ADS)

The studies of benthic calcareous foraminifera of the Maastrichtian-early Paleocene Dakhla Formation in Gebel Um El-Ghanayem (Western Desert, Egypt), improve reconstruction of depositional environments of these successions. In total, 68 taxa of benthic foraminifera were identified in the studied succession. The late Maastrichtian assemblages (Zone CF3) are dominated by calcareous foraminifera with tapered tests, this tapered taxon Loxostomum applinae, Lox. tegulatum various dentalinid taxa, and Buliminella cushmani dominate in CF3 Biozone. We thus interpret these faunas as being dominated by infaunal morphogroups, suggesting a moderately eutrophic environment. Danian assemblages are characterized by abundant epifaunal trochospiral species, such as Cibicidoides abudurbensis, Cibicidoides farafraensis, and Gyroidinoides girardanus. The infaunal morphogroups make up 25-47% of fauna in the Danian, in contrast to 62-76% in the Upper Maastrichtian. This dominance of the Danian benthic foraminiferal assemblages by epifaunal or mixed epifaunal/infaunal morphogroups suggests that the food supply to the benthos was less abundant than in the latest Cretaceous. The Cretaceous/Paleocene boundary (K/Pg) is within the upper unit of the Lower Kharga Member and marked by a hiatus in at least the top of CF3 Zone of the Upper Maastrichtian to the Lower Paleocene (base Plc Zone).

HH212 was observed with ALMA using 24 12m antennas on 2012 December 1 during the Early Science Cycle 0 phase. The shortest and longest baselines were about 20m and 360m, from which we obtained a maximum unfiltred scale of 3" at 850um. The C17O(3-2), SiO(8-7), and C34S(7-6) lines at 337061.13MHz, 347330.63MHz, and 337396.69MHz, respectively, were observed using spectral units of 488kHz (0.43km/s) resolution. Images have a typical clean-beam FWHM of (PA=35), and an rms noise of ~1mJy/beam for continuum, and 3-4mJy/beam in the 0.44km/s channels. Positions are given with respect to the MM1 protostar, located at RAJ2000=05:43:51.41, DEJ2000=-01:02:53.17, in excellent agreement with the coordinates derived by Lee et al. (2014ApJ...786..114L) using ALMA. (2 data files).

The UmGcn5 gene encoding histone acetyltransferase from Ustilago maydis is involved in dimorphism and virulence.  

PubMed

We isolated a gene encoding a histone acetyltransferase from Ustilago maydis (DC.) Cda., which is orthologous to the Saccharomyces cerevisiae GCN5 gene. The gene was isolated from genomic clones identified by their specific hybridization to a gene fragment obtained by the polymerase chain reaction (PCR). This gene (Umgcn5; um05168) contains an open reading frame (ORF) of 1421bp that encodes a putative protein of 473 amino acids with a Mr. of 52.6kDa. The protein exhibits a high degree of homology with histone acetyltransferases from different organisms. Null a2b2 ?Umgcn5 mutants were constructed by substitution of the region encoding the catalytic site with a hygromycin B resistance cassette. Null a1b1 ?Umgcn5 mutants were isolated from genetic crosses of a2b2 ?Umgcn5 and a1b1 wild-type strains in maize. Mutants displayed a slight reduction in growth rate under different conditions, and were more sensitive than the wild type to stress conditions, but more important, they grew as long mycelial cells, and formed fuzz-like colonies under all conditions where wild-type strains grew in the yeast-like morphology and formed smooth colonies. This phenotype was not reverted by cAMP addition. Mutants were not virulent to maize plants, and were unable to form teliospores. These phenotypic alterations of the mutants were reverted by their transformation with the wild-type gene. PMID:25242418

The Neoproterozoic Kolet Um Kharit bimodal metavolcanic rocks, south Eastern Desert, Egypt: a case of enrichment from plume interaction?  

NASA Astrophysics Data System (ADS)

Neoproterozoic metavolcanic rocks of Kolet Um Kharit (KUKh) in the southern Eastern Desert of Egypt have been traditionally regarded as a bimodal island-arc sequence. However, geological and geochemical arguments presented here make this interpretation doubtful. Geochemically, these rocks are classified into mafic (tholeiitic basalts) and felsic (high-K rhyodacites to rhyolites) groups. Both the KUKh mafic and felsic metavolcanic rocks show similar geochemical characteristics, implying a genetic link. They have comparable trace element ratios, such as Zr/Nb (27 30 vs. 20 36), Y/Nb (5.44 6.25 vs. 5.05 5.9), K/Rb (577 1164 vs. 573 937), Ba/La (4.29 25 9 vs. 11.4 16.2), Nb/Yb (1.82 2.03 vs. 1.76 1.99). Similarly both groups have parallel LREE-enriched patterns (La/YbCN=2.37 2.81 vs. 2.55 3.17); and negative Nb and Ta anomalies (Nb/Lapm=0.51 0.58 vs. 0.45 0.52 and Ta/Lapm=0.51 0.62 vs. 0.49 0.55). The observed negative Nb and Ta anomalies in the KUKh metavolcanic rocks cannot be attributed to crustal contamination or fractional crystallization. These rocks could represent either a remnant of break-up LIP or were derived from an enriched mantle source containing subduction components beneath an intraoceanic back-arc basin. The recognition of the KUKh rocks as derived from an enriched mantle source revives interest in models that involve enrichment from plume interaction during the evolution of the Arabian-Nubian Shield.

Remote sensing detection of gold related alteration zones in Um Rus area, Central Eastern Desert of Egypt  

NASA Astrophysics Data System (ADS)

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Phased Array L-band Synthetic Aperture Radar (PALSAR) images covering the Um Rus area in the Central Eastern Desert of Egypt were evaluated for mapping geologic structure, lithology, and gold-related alteration zones. The study area is covered by Pan-African basement rocks including gabbro and granodiorite intruded into a variable mixture of metavolcanics and metasediments. The first three principal component analyses (PCA1, PCA2, PCA3) in a Red-Green-Blue (RGB) of the visible through shortwave-infrared (VNIR + SWIR) ASTER bands enabled the discrimination between lithological units. The results show that ASTER band ratios ((2 + 4)/3, (5 + 7)/6, (7 + 9)/8) in RGB identifies the lithological units and discriminates the granodiorite very well from the adjacent rock units.The granodiorites are dissected by gold-bearing quartz veins surrounded by alteration zones. The microscopic examination of samples collected from the alteration zones shows sericitic and argillic alteration zones. The Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) supervised classification methods were applied using the reference spectra of the USGS spectral library. The results show that these classification methods are capable of mapping the alteration zones as indicated by field verification work. The PALSAR image was enhanced for fracture mapping using the second moment co-occurrence filter. Overlying extracted faults and alteration zone classification images show that the N30E and N-S fractures represent potential zones for gold exploration. It is concluded that the proposed methods can be used as a powerful tool for ore deposit exploration.

A newly discovered DLA and associated Ly? emission in the spectra of the gravitationally lensed quasar UM673A,B  

NASA Astrophysics Data System (ADS)

The sightline to the brighter member of the gravitationally lensed quasar pair UM673A,B intersects a damped Ly? system (DLA) at z = 1.62650 which, because of its low redshift, has not been recognized before. Our high-quality echelle spectra of the pair, obtained with HIRES on the Keck I telescope, show a drop in neutral hydrogen column density N(HI) by a factor of at least 400 between UM673A and UM673B, indicating that the DLA's extent in this direction is much less than the 2.7 h-170kpc separation between the two sightlines at z = 1.62650. By re-assessing this new case together with published data on other quasar pairs, we conclude that the typical size (radius) of DLAs at these redshifts is R ~= (5 +/- 3) h-170kpc, smaller than previously realized. Highly ionized gas associated with the DLA is more extended, as we find only small differences in the CIV absorption profiles between the two sightlines. Coincident with UM673B, we detect a weak and narrow Ly? emission line which we attribute to star formation activity at a rate SFR >~ 0.2Msolaryr-1. The DLA in UM673A is metal poor, with an overall metallicity ZDLA ~= 1/30Zsolar, and has a very low internal velocity dispersion. It exhibits some apparent peculiarities in its detailed chemical composition, with the elements Ti, Ni and Zn being deficient relative to Fe by factors of 2-3. The [Zn/Fe] ratio is lower than those measured in any other DLA or Galactic halo star, presumably reflecting somewhat unusual previous enrichment by stellar nucleosynthesis. We discuss the implications of these results for the nature of the galaxy hosting the DLA. Based on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and NASA, and was made possible by the generous financial support of the W. M. Keck Foundation. E-mail: rcooke@ast.cam.ac.uk

A Kinematic Approach To Assessing Environmental Effects: Star-Forming Galaxies in a z~0.9 SpARCS cluster using Spitzer 24um Observations  

E-print Network

We present an infrared study of a z=0.872 cluster, SpARCS J161314+564930, with the primary aim of distinguishing the dynamical histories of spectroscopically confirmed star-forming members to assess the role of cluster environment. We utilize deep MIPS imaging and a mass-limited sample of 85 spectroscopic members to identify 16 24um-bright sources within the cluster, and measure their 24um star formation rates (SFRs) down to ~6 Msolar/year. Based on their line-of-sight velocities and stellar ages, MIPS cluster members appear to be an infalling population that was recently accreted from the field with minimal environmental dependency on their star formation. However, we identify a double-sequenced distribution of star-forming galaxies amongst the members, with one branch exhibiting declining specific SFRs with mass. The members along this sub-main sequence contain spectral features suggestive of passive galaxies. Using caustic diagrams, we kinematically identify these galaxies as a virialized and/or backsplash...

Deep 15um AKARI observations in the CDFS: estimating dust luminosities for a MIR-selected sample and for Lyman Break Galaxies and the evolution of L(dust)/L(UV) with the redshift  

E-print Network

Deep observations of the CDFS have been secured at 15um with AKARI/IRC infrared space telescope (ESA open time). From these observations, we define a sample of MIR-selected galaxies at 15um and we also obtain 15um flux densities for a sample of LBGs at z=1 already observed at 24um with Spitzer/MIPS. Number counts for the MIR-selected sample show a bump around a 15um flux density of 0.2mJy that can be attributed to galaxies at z>0.4 and at z>0.8 for the fainter part of the bump. This bump seems to be shifted as compared to other works and a possible origin can be the Cosmic variance. Thanks to this dataset, we have tested, on the two above samples at z=1, the validity of the conversions from monochromatic luminosities nu.f(nu) at a rest-frame wavelength of 8um by a comparison with total dust luminosities estimated from Spitzer rest-frame 12um data that we use as a reference. We find that the 8um dust luminosities are not all consistent and that some of them are better when compared to L(dust) evaluated from longer wavelength luminosities. We also find that the rest-frame 8um luminosities provide globally good estimates of L(dust). By comparing our data for the two samples to several libraries of SEDs, we find that models can explain the diversity of the observed f(24)/f(15) ratio quite reasonably for the MIR-selected sample and better for the LBG sample which are less dispersed than the MIR selection. However, when we analyse the luminosity dependence of this ratio, we find important discrepancies. Finally, we revisit the evolution of L(dust)/L(UV) ratio with the redshift z by re-calibrating previous L(dust) at z=2 based on our results and added new data points at higher redshifts. The decreasing trend is amplified as compared to the previous estimate.

A full-custom ASIC design of a 8-bit, 25 MHz, Pipeline ADC using 0.35 um CMOS technology  

E-print Network

The purpose of this project was to design and implement a pipeline Analog-to-Digital Converter using 0.35um CMOS technology. Initial requirements of a 25-MHz conversion rate and 8-bits of resolution where the only given ones. Although additional secondary goals such as low power consumption and small area were stated. The architecture is based on a 1.5 bit per stage structure utilizing digital correction for each stage [12]. A differential switched capacitor circuit consisting of a cascade gm-C op-amp with 200MHz ft is used for sampling and amplification in each stage [12]. Differential dynamic comparators are used to implement the decision levels required for the 1.5-b per stage structure. Correction of the pipeline is accomplished by using digital correction circuit consist of D-latches and full-adders. Area and Power consumption of whole design was 0.24mm2 and 35mW respectively. The maximum sample rate at which the converter gave an adequate output was 33MHz.

Project UM-HAUL (UnManned Heavy pAyload Unloader and Lander): The design of a reusable lunar lander with an independent cargo unloader  

NASA Technical Reports Server (NTRS)

Project UM-Haul is the preliminary design of a reusable lunar transportation vehicle that travels between a lunar parking orbit and the lunar surface. This vehicle is an indispensible link in the overall task of establishing a lunar base as defined by the NASA Space Exploration Initiative. The response to this need consists of two independent vehicles: a lander and an unloader. The system can navigate and unload itself with a minimum amount of human intervention. The design addresses structural analysis, propulsion, power, controls, communications, payload handling and orbital operations. The Lander has the capacity to decend from low lunar orbit (LLO) to the lunar surface carrying a 7000 kg payload, plus the unloader, plus propellant for ascent to LLO. The Lander employs the Unloader by way of a motorized ramp. The Unloader is a terrain vehicle capable of carrying cargoes of 8,500 kg mass and employs a lift system to lower payloads to the ground. The system can perform ten missions before requiring major servicing.

A linear 0.18 um CMOS Distributed Low Noise Amplifier from 3.1 to 10.6 GHz with Cascode Cells  

NASA Astrophysics Data System (ADS)

In this paper, we propose a design methodology of 3.1-10.6GHz Ultra-wideband (UWB) Distributed Low Noise Amplifier using standard 0.18 um CMOS technology which is applicable in telecommunication. The four cells DLNA, each cell contains cascode architecture, can be use in broadband applications. The proposed distributed low noise amplifier has a good input and output matching over the full band of 3.1-10.6 GHz. We achieve acceptable results for low noise amplifier as a flat power gain of 12.5 dB (S21) from 3.1 to 10.6 GHz, which is ripple 0.3 dB over the full UWB band. An input impedance matching is <-15 dB (S11) and an output impedance matching of <-15 dB (S22) over the entire band. Our measurements show this LNA achieves the minimum noise figure of 2.8 dB.

Diffraction-limited 3 um Spectroscopy of IRAS 04296+3429 and IRAS 05341+0852: Spatial Extent of Hydrocarbon Dust Emission and Dust Evolutionary Sequence  

E-print Network

We present 3 um spectroscopy of the carbon-rich proto-planetary nebulae IRAS 04296+3429 and IRAS 05341+0852 conducted with the adaptive optics system at the Subaru Telescope. We utilize the nearly diffraction-limited spectroscopy to probe the spatial extent of the hydrocarbon dust emitting zone. We find a hydrocarbon emission core extending up to 100--160 mas from the center of IRAS 04296+3429, corresponding to a physical diameter of 400--640 AU, assuming a distance of 4 kpc. On the other hand, we find that IRAS 05341+0852 is not spatially resolved with this instrumentation. The physical extent of these proto-planetary nebulae, along with the reanalyzed data of IRAS 22272+5435 published previously, suggests a correlation between the physical extent of the hydrocarbon dust emission and the spectral evolution of the aliphatic to aromatic features in these post-AGB stars. These measurements represent the first direct test of the proposed chemical synthesis route of carbonaceous dust in the circumstellar environment of evolved stars.

Characterization of 1.3-um wavelength GaInNAs/GaAs edge-emitting and vertical-cavity surface-emitting lasers using low temperature and high pressure  

NASA Astrophysics Data System (ADS)

By measuring the spontaneous emission from normally operating ~1.3um GaInNAs/GaAs-based lasers grown by MBE and by MOVPE we have quantitatively determined the variation of monomolecular (defect-related ~An), radiative (~Bn2) and Auger recombination (~Cn3) as a function of temperature from 130K to 370K. We find that A, B and C are remarkably independent of the growth method. Theoretical calculations of the threshold carrier density as a function of temperature were also performed using a 10 band ?p Hamiltonian from which we could determine the temperature variation of A, B and C. At 300K, A=11x10-8 sec-1, B=8x10-11 cm3 sec-1 and C= 6x10-29 cm6 sec-1. These are compared with theoretical calculations of the coefficients and good agreement is obtained. Our results suggest that by eliminating defect-related currents and reducing optical losses, the threshold current density of these GaInNAs/GaAs-based edge-emitting devices would be more than halved at room temperature. The results from studies of temperature and pressure variation of ~1.3um VCSELs produced by similar MBE growth could also be explained using the same recombination coefficients. They showed a broad gain spectrum and were able to operate over a wide temperature range.

A novel solution to the gated x-ray detector gain droop problema)  

NASA Astrophysics Data System (ADS)

Microchannel plate (MCP), microstrip transmission line based, gated x-ray detectors used at the premier ICF laser facilities have a drop in gain as a function of mircostrip length that can be greater than 50% over 40 mm. These losses are due to ohmic losses in a microstrip coating that is less than the optimum electrical skin depth. The electrical skin depth for a copper transmission line at 3 GHz is 1.2 ?m while the standard microstrip coating thickness is roughly half a single skin depth. Simply increasing the copper coating thickness would begin filling the MCP pores and limit the number of secondary electrons created in the MCP. The current coating thickness represents a compromise between gain and ohmic loss. We suggest a novel solution to the loss problem by overcoating the copper transmission line with five electrical skin depths (6 ?m) of Beryllium. Beryllium is reasonably transparent to x-rays above 800 eV and would improve the carrier current on the transmission line. The net result should be an optically flat photocathode response with almost no measurable loss in voltage along the transmission line.

The airbag problema potential culprit for bench-to-bedside translational efforts: relevance for Alzheimers disease  

PubMed Central

For the last 20years, the amyloid cascade hypothesis has dominated research aimed at understanding, preventing, and curing Alzheimers disease (AD). During that time researchers have acquired an enormous amount of data and have been successful, more than 300 times, in curing the disease in animal model systems by treatments aimed at clearing amyloid deposits. However, to date similar strategies have not been successful in human AD patients. Hence, before rushing into further clinical trials with compounds that aim at lowering amyloid-beta (A?) levels in increasingly younger people, it would be of highest priority to re-assess the initial assumption that accumulation of A? in the brain is the primary pathological event driving AD. Here we question this assumption by highlighting experimental evidence in support of the alternative hypothesis suggesting that APP and A? are part of a neuronal stress/injury system, which is up-regulated to counteract inflammation/oxidative stress-associated neurodegeneration that could be triggered by a brain injury, chronic infections, or a systemic disease. In AD, this protective program may be overridden by genetic and other risk factors, or its maintenance may become dysregulated during aging. Here, we provide a hypothetical example of a hypothesis-driven correlation between car accidents and airbag release in analogy to the evolution of the amyloid focus and as a way to offer a potential explanation for the failure of the AD field to translate the success of amyloid-related therapeutic strategies in experimental models to the clinic.

High-resolution superconducting x-ray spectrometers with an active area of 282 um x 282 um  

SciTech Connect

Superconducting tunnel junctions coupled to superconducting absorbers may be used as high-resolution, high-efficiency X-ray spectrometers. We have tested devices with niobium X-ray absorbing layers coupled to aluminum layers that serve as quasiparticle traps. In this work we measured the current pulses from a large area tunnel junction using an amplifier based on an array of 100 SQUIDs. Using this amplifier and a 282 micron X 282 micron junction, we have measured an energy resolution of 19 eV FWHM for 1.5 keV X rays and 21 eV for 2.6 keV X rays. The area of this junction is eight times the area of any junction previously measured to have such high energy resolution.

Datirovka zvezdnogo kataloga Ptolemeya po sobstvennym dvizheniyam: tysyacheletnyaya problema reshena %t Dating Ptolemy's star catalogue based on proper motions: the thousand-year-old problem solved  

NASA Astrophysics Data System (ADS)

The thousand-year-old problem of the origin of the star catalogue included in Ptolemy's "Almagest" is considered. The dilemma whether stellar coordinates were based on Hipparchus' or Ptolemy's observations has arisen long ago, because the 1 degree error in ecliptic longitudes may be explained either by Ptolemy's error in the initial longitudes of the Sun, or by the fact that Ptolemy adopted the original Hipparchus' coordinates and transformed them to a 265-year later epoch using an erroneous constant for precession. In fact, only indirect evidence for the Hipparchan origin of most of the coordinates was available so far, and most specialists considered the issue still to be resolved. We have successfully applied a new approach based on stellar proper motions. The time-dependent mutual distances in the configurations including 8 fast stars yield an epoch of -53 130 B.C., whereas the bulk method based on an analysis of the Almagest minus computed coordinate differences for 40 fastest stars yields an epoch of -90 120 B.C. Standard errors in the ancient ecliptic longitudes and latitudes are found to be ?(?cos?) = 18' and ?? = 13', respectively. It is concluded that the stellar coordinates in the Almagest catalogue were observed during Hipparchus' lifetime and that Ptolemy's authorship claim can be rejected at a 94% significance level. Ptolemy's assertion that "we observed as many stars as we could sight down to the sixth magnitude" might simply imply that he found each star of the original catalogue to be near its position in the sky given by Hipparchus, and then adopted Hipparchus' coordinates as measured by a more skilled observer.

Comparing the use of 4.6 um lasers versus 10.6 um lasers for mitigating damage site growth on fused silica surfaces  

SciTech Connect

The advantage of using mid-infrared (IR) 4.6 {micro}m lasers, versus far-infrared 10.6 {micro}m lasers, for mitigating damage growth on fused silica is investigated. In contrast to fused silica's high absorption at 10.6 {micro}m, silica absorption at 4.6 {micro}m is two orders of magnitude less. The much reduced absorption at 4.6 {micro}m enables deep heat penetration into fused silica when it is heated using the mid-IR laser, which in turn leads to more effective mitigation of damage sites with deep cracks. The advantage of using mid-IR versus far-IR laser for damage growth mitigation under non-evaporative condition is quantified by defining a figure of merit (FOM) that relates the crack healing depth to laser power required. Based on our FOM, we show that for damage cracks up to at least 500 {micro}m in depth, mitigation using a 4.6 {micro}m mid-IR laser is more efficient than mitigation using a 10.6 {micro}m far-IR laser.

Mild steels coated with 14% manganese covered electrodes (E7-UM-200-K and E1-UM-350): Phenomena at the steel-coating interface  

SciTech Connect

In this work the authors have studied the phenomena in the interface of the coating made on soft carbon steel with electrodes with a high content of manganese. The study has been done with scanning electron microscope and X-rays mapping images. These images show how the alloy elements are distributed in each of the constituent elements presented in the interface, and the nature of these constituents. These results have allowed us to verify that many of the problems that arise in homogeneous joints, as such localised corrosion, low interface resistance, etc., happened, precisely in these regions. As a help to determine the nature of the constituent elements, microhardness measurements have also been made.

High-performance 0.25-um CMOS technology for fast SRAMs  

NASA Astrophysics Data System (ADS)

A high performance 0.25 micrometers CMOS process has been developed for fast static RAMs. This technology features retrograde wells, shallow trench isolation scalable to a 0.45 micrometers active pitch, surface channel 0.25 micrometers NMOS and PMOS transistors with a 55 angstroms nitrided gate oxide providing drive currents of 630 and 300 (mu) A/micrometers respectively at off-leakages of 10 pA/micrometers , overgated TFTs with an on/off ratio greater than 6(DOT)105, stacked capacitors for improved SER protection, five levels of polysilicon planarized by chemical-mechanical polishing with two self-aligned interpoly contacts, 0.35 micrometers contacts and a 0.625 metal pitch. In this technology, a triple well structure was used for SER protection. High energy retrograde wells were integrated with shallow trench isolation and epi providing excellent interwell isolation for both leakage and latch-up down to n+/p+ spaces of 0.60 micrometers . PMOS transistors were scaled to a physical gate length of 0.1 micrometers while maintaining excellent short channel characteristics. A split word-line bitcell was scaled to 1.425 micrometers X 2.625 micrometers equals 3.74 micrometers 2 using 0.25 micrometers rules. A tungsten interpoly plug was used to connect the PMOS TFT loads to the underlying NMOS latch gates without a parasitic diode or dopant interdiffusion, connecting 3 polysilicon layers with self-aligned isolation from an intervening polysilicon layer used as a local interconnect. With this plug, TFT drive currents were greatly improved, particularly at low voltages and the memory nodes pulled to the fully supply voltage. Functional 0.25 micrometers bitcells were demonstrated and with an LDD resistor it was possible to double the cell stability. Bitcell simulation was used to demonstrate that a 4T bitcell will be stable at 2.5 V but that a word-line boost will be required for 1.8 V operation.

One group of the mirrors which have been investigated are commercially available polished uncoated Mo- and Cu- mirrors. A second set of mirrors consists of copper mirrors coated with NiCu, or Aumax, layer systems for enhanced reflectivity. NaCl and ZnSe substrates were selected as IR transparent materials. For measuring the photoacoustic waves generated by laser pulse irradiation, a piezoceramic detector is used. The amplified signal of the detector is sampled by a digital oscilloscope.

New semiconductor diode laser emitting at 2 um for microsurgery applications  

NASA Astrophysics Data System (ADS)

A surgical laser instrument is presented, based on a semiconductor diode emitting in the spectral region around 2 micrometer, in continuous mode. At this wavelength tissue absorption is via histological water, and the interaction is purely thermal. A portable laser station was built, emitting up to 250 mW of optical power at 1.94 micrometers, out of the tip of a low- hydroxil fused-silica optical fiber of 200 micrometer diameter. Experiments have been performed both in vitro with enucleated porcine eyes and in vivo, on rabbits and rats. In vitreo-retinal surgery, retinectomies and incisions of epiretinal fibrotic membranes have been achieved. At reduced output power the laser radiation has been applied to the welding of tissues, in particular cornea, sclera and skin, with interesting results. This new laser source, characterized by ergonomic advantages like compactness, portability, long lifetime, reduced maintenance, is potentially attractive for a number of microsurgical procedures like micro- incisions, shallow coagulations, and welding of hydrated biological membranes.

VizieR Online Data Catalog: MIPS 24um calibrators (Engelbracht+, 2007)  

NASA Astrophysics Data System (ADS)

The data were all obtained using the MIPS small-field photometry mode astronomical observation template (AOT). For most targets, two cycles of photometry using 3s exposures were obtained, resulting in 14 individual images at each of two telescope nod positions (excluding the short exposure that starts the data-taking sequence at each of the two telescope nod positions). Starting with the raw data downloaded from the Spitzer Science Center (SSC), these data were processed using version 3.06 of the MIPS Data Analysis Tool (DAT; Gordon et al., 2005PASP..117..503G), which performs standard processing of infrared detector array data (slope fitting, dark subtraction, linearity correction, flat fielding, and mosaicking), as well as steps specific to the array used in MIPS (droop correction and dynamic range extension using the first difference frame) -- these steps are described in more detail in the paper.

Diffractive lens in 8-10 to um forward-looking infrared  

NASA Astrophysics Data System (ADS)

We realize for the first time a forward-looking IR (FLIR) system using a diffractive optical element (DOE) in its optics made of germanium in the 8- to 10-micrometers IR wavelength. We describe the design and the performance of the DOE optics. The IR diffractive lens made of germanium is proposed to correct the axial chromatic aberration in optics of the FLIR system. Compared with conventional optics of an FLIR system the optics using a DOE singlet instead of ZnSe achromat, we have a DOE system modulation transfer function (MTF) that is almost equal to the conventional one. The DOE singlet instead of ZnSe achromat appears to be enough to compensate for the chromatic aberration of the optical system. Using the DOE system, the numbers of lens elements, the mass, and the cost are reduced.

Benefits of a new converging beam scanning method for 8- to 12-um range imaging systems  

NASA Astrophysics Data System (ADS)

Most 8 - 12 micron infrared imaging optical systems consist of a telescope, angular scanner for parallel beams (polygon or nodding mirror type) and a detector lens. The telescope for all magnification modes, and the detector lens system, each one separately, have to be designed close to their diffraction limit over all scanned FOV to withstand the severe resolution requirements of the entire IR system. This fact mandates several aspherical surfaces for the telescope and the detector lens systems, for purposes of residual aberration correction. This paper describes an 8 - 12 micron FLIR in which, owing to the proposed lateral scanner for converging beams, the optical system is reduced to an objective only attached to the proposed lateral scanner which fulfills lateral scanning of the scenery image in the detector plane.

Peculiarities of coagulation action of IR lasers (1-3 um) radiation on cornea  

NASA Astrophysics Data System (ADS)

Antiviral, antibacterial, antitumoral effects of laser coagulation are now of great importance in clinical ophthalmology for different corneal diseases treatment. One can note, that nowadays solid-state free-mode pulsed near-and-mid-infrared lasers with the 1.3 - 3.0 micrometers wavelengths may become widespreadly accepted in this field of ophthalmosurgery. The corneal tissue absorption coefficients for these wavelengths are lying from some parts to several thousand cm-1. Thus, by proper selection of laser wavelength, possibility is appeared to coagulate precisely the seat of pathological alterations without damaging of more deeper, non changed corneal tissue. In our work the comparative experimental study results of rabbit cornea coagulation after exposure with using of different IR lasers (with 1.32; 1.54; 1.96; 2.09 and 2.84 micrometers wavelengths) are presented. Pulse duration was about 10-3 s. The subthreshold, threshold and superthreshold energy levels were studied. Threshold energies were registered if slightly noticed coagulative changes appeared in exposed volume of corneal tissue. The cornea response resulting from laser radiation exposure was evaluated by clinical examination, slit lamp biomicroscopy, light microscopy, fluorescent staining and biochemistry. For all wavelengths initial damage was found within the cornea layers. Superthreshold injury revealed the same picture except that for 1.32 micrometers the threefold increase of the threshold energy caused additionally iris injury. The damages of the cornea were marked near the surface, stretched to more deeper layers, and damage zones were extended from the epithelium for 2.84 micrometers wavelength to whole cornea thickness for 1.32 and 1.54 micrometers wavelengths and have intermediate position for 1.96 and 2.09 micrometers wavelengths, depending on the corneal absorption coefficient. Quantitative results of threshold energy levels were calculated by probit-analysis. The radiant exposure (HD50), that cause the threshold coagulation changes in cornea with 50% probability was determined for the beam diameter (irradiance diameter) of 2 mm and for 1.32; 1.54; 1.96; 2.09 and 2.84 micrometers wavelengths. Values determined were (2.4 +/- 0.2) X 10; 7.2 +/- 0.6; 2.9 +/- 0.5; 3.7 +/- 0.2; (1.9 +/- 0.4) X 10-1 J/cm2. These values are well-correlated to corneal absorption coefficients. The absorption coefficient the higher, the value HD50 the lower and the `danger' for ocular structures damage also the lower. This fact is needed to be taken into account, because of normative documents did not reflect it in 1.3 - 3.0 micrometers wavelength range. The obtained results may be used for development of new clinical laser applications and refinement of the laser safety standards.

Compact dual wavelength 3.30 to 3.47-um DIAL lidar  

NASA Astrophysics Data System (ADS)

A compact (2'6' X 2'5' X 1'1') 3.30 - 3.47-micrometers DIAL lidar has been constructed for base remediation and chemical monitoring. The lidar system is designed for short range (0.5 km maximum) aerosol backscatter detection of light hydrocarbons with sensitivities at parts-per-million level in a 30-m ranging bin. The system can also operate in the topographic mode. The on-line and off-line wavelengths are produced sequentially using a dual crystal intra-cavity KTA OPO. Detection is by means of an 8-in Newtonian telescope coupled to a Stirling cycle cooled InSb detector. The system incorporates an onboard digital signal processor and controller, operator's interface is furnished by a laptop PC. Results of initial tests using diesel fuel and a solvent are presented.

High-speed interconnect using 1.3 um laser and fiber array  

NASA Astrophysics Data System (ADS)

Multifiber optic interconnects are attractive for high- throughput computer systems and asynchronous transfer mode (ATM) switching systems. We have developed a high- performance 10-fiber interconnect with each fiber operating at a high speed of 1 Gb/s. The modules have a receptacle for mechanically transferred push-on (MTP) multifiber push pull connector. The hermetic package is surface mount type and solder reflowable. The transmitter (Tx) is dc-coupled and the receiver (Rx) is ac-coupled with a cutoff of 7 kHz. The electrical interface is differential current mode logic (CML) or emitter coupled logic (ECL), and the optical interface is a 12-fiber connector. Single-mode glass fibers (9.5 micrometer) or multimode glass graded-index fibers (62.5 micrometer) were used. Tx contains a laser-driver IC, while Rx contains pre-amplifier and postamplifier, and comparator circuits. All the ICs are minus 5.2 V bipolar GaAs, and Tx plus RX consumes 4 W. The power in a fiber is about 100 (mu) W. The back-to-back skew is less than 80 ps. For a non-return-to-zero (NRZ) 223-1 pseudo-random bit stream, the error rate was less than 10 -12 with all the channels transmitting different signals simultaneously and a 100-m small-skew (1.2 ps/m) fiber ribbon. The link worked up to an atmosphere temperature of 80 degrees Celsius.

DualBeam metrology: a new technique for optimizing 0.13-um photo processes  

NASA Astrophysics Data System (ADS)

A DualBeam Metrology system was investigated for the application of obtaining 3-dimensional (3D) characterization of a 130 nm ground rule KrF photolithography process. Integrated circuit devices are 3-dimensional in structure and, hence, should be best characterized using 3-dimensional techniques to ensure adherence to the design architecture and the desired process window for manufacturing. The need for 3D metrology is further required for the characterization and monitoring of critical layer processes and equipment performance. The metrology used in this investigation is a novel technique for critical feature cross sectioning. The process for DualBeam metrology uses a focused ion beam (FIB) for milling or cutting the cross section through the photoresist or process film. An integrated scanning electron microscope (SEM) provides high-resolution imaging of the features, and a flexible automated metrology package collects and analyzes the data. To demonstrate the feasibility of the technique, critical dimension (CD) data and sidewall angle (SWA) measurements were captured from 130 nm lines and 150 nm contacts at 1:1 densities. The critical criteria for the characterization of the photolithography process window are CD control, depth of focus (DOF), exposure latitude, and feature sidewall angle or profile. Using the DualBeam technique, 2D and 3D data are captured on a single machine platform using a cut, look, and measure routine. A further benefit is the availability of high-resolution cross-sectional SEM images that can be used qualitatively to validate the quantitative data. The results presented here show the performance of this 130 nm ground rule process and the benefits of utilizing this efficient characterization technique.

Lack of dentin acid resistance following 9.3 um CO2 laser irradiation  

Microsoft Academic Search

Previous studies have shown that laser irradiation of dental enamel by specific carbon dioxide laser conditions can inhibit subsequent acid dissolution of the dental enamel surface. The purpose of this study was to determine whether similar carbon dioxide laser conditions would have a protective effect on dentin. Blocks of human dentin roots (3x3 mm2) were irradiated at 9.3 m wavelength

The morphology and the chemistry of dental enamel and dentin can be modified by irradiation with a CO2 laser to increase the acid resistance of the intrinsic mineral. The changes induced in hard dental tissues after laser irradiation are predominantly determined by the photothermally induced temperature rise in the tissue. Therefore the temperature rise in the irradiated enamel and dentin

Effect of the CO2 laser (9.6um) on the dental pulp in humans  

Microsoft Academic Search

There has been great interest in the potential use of a laser to replace the dental handpiece (drill). Ideally a laser emitting radiation that is absorbed strongly by both the water and hydroxyapatite in teeth, would be a more efficient laser. Previous investigators showed that the 9.3 and 9.6 micron wavelength bands of the CO2 laser contain hydroxyapatite absorption peaks.

Low-dispersion penalty directly modulated 1.55-um DFB lasers with complex coupled gratings  

NASA Astrophysics Data System (ADS)

Prior to the full maturation of electro-absorption modulated laser technology, directly modulated 1.55 micrometer distributed feedback lasers will continue to play a central role in long haul, high bit rate, optical communications systems. Maintaining a competitive advantage, however, requires that these devices be optimized for long fiber length transmission, high power, and low cost. In this talk we discuss the design elements needed to accomplish this. Focus is placed on factors leading to reduction of the linewidth enhancement factor, (alpha) . In particular, the role played by complex gratings is examined. We demonstrate typical cw (alpha) values of 1.65 can be achieved in a robust and manufacturable device. This device is shown to readily serve 2.5 Gb/s applications with span lengths of 200 km (approximately 3600 ps/nm).

Experimental study of biological effect by Nd:YAP laser (1.34um)  

NASA Astrophysics Data System (ADS)

Objective: To evaluate the biological effect of different power, irradiation time of Nd: YAP laser (1341nm). Method: The canine skin, bronchia, stomach, bladder, uterus were irradiated with different irradiation power and time. The effect was observed by naked eyes, light microscope, and electric microscope. Result: Having positive correlation with power and irradiating time, the biological effect of Nd: YAP laser is mainly thermal coagulation effect with some gasified ablation effect. Under the condition where the diameter of faculae irradiating on canine skin was 3 mm, the thermal coagulation dose reaching deep derma was 5W 4s, 10w 1s?the thermal coagulation dose puncturing the whole layer was 5W, 6s, 10W, 4s; the thermal coagulation dose reaching whole stratum was 10W 5s, 20W 4s, 30W 2s, 40-60W 1s on stomach (Thickness 6mm), was 40W, 2s, 30W, 3s, 20W, 4s, 10W, 6s on bladder (Thickness 6mm ,irradiation underwater), was 10W, 4s on bronchia (Thickness 2 mm) and was 30W 3s, 20W 5s, 10W 6s on uterus (Thickness 6mm). Conclusion: Having positive correlation with power and irradiating time, the biological effect of Nd: YAP laser is mainly thermal coagulation effect with some gasified ablation effect. Under the condition where the diameter of faculae irradiating on canine skin was 3 mm, it is safe when the dose is 5W, and the irradiating time is less than 4s; the dose is 10W, and the irradiating time is less than 1 s. Under these conditions, the gastric area is used to coagulating and ablating. It is safe when the dose is less than 10W 5s, 20W 4s, 30W 2s. Under these condition, The bladder (thickness 6mm) is coagulated and ablated. It is safe when the dose is no more than 40W, 1s, 30W, 2s, 20W, 3s, 10W, 5s.Under the condition where bronchia (thickness 2mm) is coagulated and ablated, it is safe when the dose is less than 10W, 3s.Under the condition where uterus (thickness 6mm) is coagulated and ablated, it is safe when the dose is less than 30W, 2s, 20W, 4s, 10W, 5s.

NASA Astrophysics Data System (ADS)

The attempt to reconstruct the Hipparchus system of is proposed. The offered analysis of certain passages in the treatises of Ptolemy, Pliny, and Strabo allows to trace the latent semantic connection between them and to advance a hypothesis to clarify it. Ptolemy's passage (sect. 3) states Hipparchus to propose in his geography a certain system of meridians and to use the -330, Sept. 20 eclipse to determine the relative longitudes of Arbela and Carthage. Pliny's evidence (4) shows that Hipparchus must have known about the observation of this eclipse from Sicily, which demands to situate this island far eastward of Carthage. Strabo's data (5) confirm that Hipparchus, while criticising Eratosthenes, suggested situating Sicily far eastward of Carthage. Ptolemy's data (6) show that Marinus, whose work Ptolemy's geography was based on, in his early redaction, must situate Sicily farther eastward than in the final variant. Posidonius' passage (7) demonstrates the latitude of Sicily in Ptolemy's geography to go back to Hipparchus. In "Almagest" (9) the longitude of Babylon (relative to Alexandria) is directly ascribed to Hipparchus and the longitude of Rome agrees with that of Sicily in Pliny's evidence. The data of Ptolemy's geography (9.3-9.5) permit that Arbela and Babylon were situated on the same meridian initially. All these enable us to suggest that Hipparchus determined the longitudes not only of Arbela and Babylon, but also of Babylon and Sicily, Alexandria and Rome.

Room temperature continuous wave InGaAsN quantum well vertical cavity lasers emitting at 1.3 um  

SciTech Connect

Selectively oxidized vertical cavity lasers emitting at 1294 nm using InGaAsN quantum wells are reported for the first time which operate continuous wave at and above room temperature. The lasers employ two n-type Al{sub 0.94}Ga{sub 0.06}As/GaAs distributed Bragg reflectors each with a selectively oxidized current aperture adjacent to the optical cavity, and the top output mirror contains a tunnel junction to inject holes into the active region. Continuous wave single mode lasing is observed up to 55 C. These lasers exhibit the longest wavelength reported to date for vertical cavity surface emitting lasers grown on GaAs substrates.

Performance of various quantum key distribution systems using 1.55 um up-conversion single-photon detectors  

E-print Network

We compare the performance of various quantum key distribution (QKD) systems using a novel single-photon detector, which combines frequency up-conversion in a periodically poled lithium niobate (PPLN) waveguide and a silicon avalanche photodiode (APD). The comparison is based on the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984 (BB84), the Bennett, Brassard, and Mermin 1992 (BBM92), and the coherent differential phase shift keying (DPSK). We show that the up-conversion detector allows for higher communication rates and longer communication distances than the commonly used InGaAs/InP APD for all the three QKD protocols.

A scheme for INAA of 25 elements: As, Ba, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Nd, Rb, Sc, Sm, Th, U, Yb, Zn and Zr in quartz collected from the eastern desert along the Egyptian Red Sea coast is proposed. The samples were prepared together with standard reference material and irradiated in a neutron flux of 710(11)n/cm(2)s in the TRIGA Mainz research reactor facilities. The gamma spectra were collected by a HPGe detector and the analysis was done by a computerized multichannel analyzer.The accuracy of the procedure is evaluated by the analysis of two geo-standard reference materials (Dolerite WSE and Microgabro PMS). The choice of the nuclear reaction, irradiation and decay times and of the proper gamma radiation in counting are presented and discussed. The data presented here are our contribution to understanding the elemental composition of the quartz rock. Because there are no existing databases for the elemental analysis of quartz, our results are a start to establishing a database for the Egyptian quartz. It is hoped that the data presented here will be useful to those dealing with geochemistry, quartz chemistry and related fields. PMID:23954747

We use time-resolved degenerate four-wave-mixing with femtosecond pulses to measure both the phase and magnitude of (chi) 1111. Our data are well defined in terms of a single two-photon resonance at a fundamental wavelength of 930 nm. From our fit parameters, we predict for (chi) 1111 in the zero-frequency limit a value of (9 +/- 3) X 10-13 esu and at the resonance maximum a value of i(3.9 +/- 0.6) X 10-12 esu.

1.9-um diode-laser-assisted anastomoses in reconstructive microsurgery: preliminary results in 12 patients  

NASA Astrophysics Data System (ADS)

The authors reported an original 1.9 micrometer diode laser assisted microvascular anastomosis (LAMA) in human. This technique has been applied in 12 patients during reconstructive surgery for digital replantations (n equals 2), for digital revascularizations (n equals 3) and for free flap transfers (n equals 7). Fourteen end-to-end anastomoses (10 arteries, 4 veins) were performed. LAMA were always performed on vessel which did not impede the chance of success of the surgical procedure in case of thrombosis. LAMA was performed with a 1.9 micrometer diode laser after placement of 2 equidistant stitches. The didoes spot was obtained by means of an optic fiber transmitted to the vessel wall via a pencil size hand piece. The used parameters were as followed: spot size equals 400 micrometer, power equals 70 to 220 mW, time equals 0.7 to 2 seconds, mean fluence equals 115 J/cm2. The mechanism involved is a thermal effect on the collagen of the adventitia and media leading to a phenomena which the authors have termed 'heliofusion.' This preliminary trial has permitted to define the modalities of its use in human. The technique is simple, rapid and easily learned. The equipment is not cumbersome, sterilizable and very ergonomic. LAMA does not replace sutures but is complementary, thanks to a reduction in the number of stitches used and to an access to surgical areas which are not easily accessible. This study must be completed by a larger scale study to confirm this technique and its reliability. Others uses could performed on different tissues such as biliary and urinary track, specially under laparoscopic conditions.

Benchmarking of advanced CD-SEMs against the new unified specification for sub-0.18-um lithography  

NASA Astrophysics Data System (ADS)

The Advanced Metrology Advisory Group (AMAG) comprised of representatives from International SEMATECH consortium member companies and the National Institute of Standards and Technology have joined to develop a new unified specification for an advanced scanning electron microscope critical dimension measurement instrument (CD-SEM). (Allgair, et al., 1998) This paper describes the results of an effort to benchmark six CD-SEM instruments according to this specification. The consensus among the AMAG metrologists was that many critical areas of performance of CD-SEMs required improvement. Following this assessment this specification for benchmarking was developed. The advanced CD-SEM specification addresses several critical areas for improvement, each with its own a separate section. The critical areas covered are: precision, accuracy, charging and contamination, performance matching, pattern recognition and stage navigation accuracy, throughput, and instrumentation outputs. Each section of the specification contains a concise definition of the respective performance parameter, and wherever appropriate refers to ISO definitions. The test methodology is described, complete with the relevant statistical analysis. Many parameters (including precision, matching, and magnification accuracy) are numerically specified to be consistent with the International Technology Roadmap for Semiconductors (ITRS, 1999). Other parameters, such as charging and linewidth accuracy, are targeted with guidelines for improvement. The test wafers developed for determining the level of compliance with the specification are also discussed. The AMAG circulated this report among the metrology instrument suppliers and conferred with them. Certain components of the specification have already been adopted by some of the manufacturers in their newer metrology instruments. International SEMATECH fabricated the AMAG test wafers described herein. Measurements on six state-of-the-art metrology instruments using the AMAG test wafers have been carried out and the results were processed according to this specification. A review of the results is presented in this paper.

NASA Astrophysics Data System (ADS)

We present the development of a near infrared image intensifier tube based on a Generation III configuration. The photocathode driving this tube is based on a negative-electron-affinity (NEA) InGaAs design. The surface and crystalline quality of the InGaAs active layer for this device is characterized by x-ray diffraction (XRD), micro-Raman spectroscopy, energy dispersive x-rays (EDX), and Auger spectroscopy. Room temperature and 77 K photoluminescence (PL) and transmission measurements indicate the near infrared responsivity (1.2 - 1.7 micrometers ) of the InGaAs active layer. Reflection mode measurements of the photoresponse (PR) in an ultra high vacuum environment produced white light sensitivities of 100 (mu) A/lumen and quantum efficiencies of approximately 1% for wavelengths of 1300 - 1600 nm at 300 K. Sealed image tubes were created, and early sealed tube results show low quantum efficiencies (approximately 0.1% 1550 nm) due to nonoptimized active layer thickness.

Epitaxial growth of HgCdTe 1.55-um avalanche photodiodes by molecular beam epitaxy  

NASA Astrophysics Data System (ADS)

Separate absorption and multiplication avalanche photodiode (SAM-APD) device structures, operating in the 1.1 - 1.6 micrometer spectral range, have been fabricated in the HgCdTe material system by molecular-beam epitaxy. These HgCdTe device structures, which offer an alternative technology to existing III-V APD detectors, were grown on CdZnTe(211)B substrates using CdTe, Te, and Hg sources with in situ In and As doping. The alloy composition of the HgCdTe layers was adjusted to achieve both efficient absorption of IR radiation in the 1.1 - 1.6 micrometer spectral range and low excess-noise avalanche multiplication. To achieve resonant enhancement of hole impact ionization from the split-off valence band, the Hg(subscript 1-x)Cd(subscript x)Te alloy composition in the gain region of the device, x equals 0.73, was chosen to achieve equality between the bandgap energy and spin-orbit splitting. The appropriate value of this alloy composition was determined from analysis of the 300 K bandgap and spin-orbit splitting energies of a set of calibration layers, using a combination of IR transmission and spectroscopic ellipsometry measurements. MBE-grown APD epitaxial wafers were processed into passivated mesa-type discrete device structures and diode mini-arrays using conventional HgCdTe process technology. Device spectral response, dark current density, and avalanche gain measurements were performed on discrete diodes and diode mini- arrays on the processed wafers. Avalanche gains in the range of 30 - 40 at reverse bias of 85 - 90 V and array-median dark current density below 2 X 10(superscript -4) A/cm(superscript 2) at 40 V reverse bias have been demonstrated.

NASA Astrophysics Data System (ADS)

The scattered light from dust-contaminated mirrors was measured at (lambda) equals 10.6 micrometers , and results are compared to that predicted by a modified Mie theory. The theory is in good agreement with experiment. The far-infrared measurements of the `clean' mirrors were, for angles beyond about 8 deg from specular, limited by the scatter from particulates and not the surface microroughness. Similar limitations can be experienced by other irregularities such as scratches, digs, and pinholes in coatings. It is shown that contaminant scatter dominance in the far-infrared requires only a few very small particles, so the necessity for good cleaning techniques and good clean room practice is quite evident.

Fabrication of 0.25-um electrode width SAW filters using x-ray lithography with a laser plasma source  

NASA Astrophysics Data System (ADS)

A process for the fabrication of surface acoustic wave (SAW) devices with line widths of 250 nm and less, based on x-ray lithography using a laser-plasma source has been developed. The x-ray lithography process is based on keV x-ray emission from Cu plasma produced by 15 Hz, 50 ps, 248 nm KrF excimer laser pulses. The full structure of a 2 GHz surface acoustic wave filter with interdigital transducers in a split-electrode geometry has been manufactured. The devices require patterning a 150 nm thick aluminum layer on a LiNbO3 substrate with electrodes 250 nm wide. The manufacturing process has two main steps: x-ray mask fabrication employing e-beam lithography and x-ray lithography to obtain the final device. The x-ray masks are fabricated on 1 micrometers thick membranes of Si2N4. The line patterns on the masks are written into PMMA resist using a scanning electron microscope which has been interfaced to a personal computer equipped to control the x and y scan voltages. The opaque regions of the x-ray mask are then formed by electroplating fine grain gold into the open spaces in the etched PMMA. The mask and sample are mounted in an exposure cassette with a fixed spacer of 10 micrometers separating them. The sample consists of a LiNbO3 substrate coated with Shipley XP90104C x-ray resist which has been previously characterized. The x-ray patterning is carried out in an exposure chamber with flowing helium background gas in order to minimize debris deposition on the filters. After etching the x-ray resist, the final patterns are produced using metallization and a standard lift-off technique. The SAW filters are then bonded and packaged onto impedance matching striplines. The resultant devices are tested using Scalar Network Analyzers. The final devices produced had a center frequency of 1.93 GHz with a bandwidth of 98 MHz, close to the expected performance of our simple design.

Chemical optimization of resist/developer systems tuned for sub-0.4-um process window expansion  

NASA Astrophysics Data System (ADS)

In order to perform 0.2 micrometer processes, one needs to study the diffusion of photoacid generators within the photoresist system, since diffusion during post exposure bake time has an influence on the critical dimension (CD). We have developed a new method to study the diffusion of photoacid generators within a polymer film. This new method is based on monitoring the change of the fluorescence intensity of a pH- sensitive fluorescent dye caused by the reaction with photoacid. A simplified version of this experiment has been conducted by introducing acid vapor to quench the fluorescence intensity of this pH sensor. A thin polymer film is spin cast onto the sensor to create a barrier to the acid diffusion process. During the acid diffusion process, the fluorescence intensity of this pH sensor is measured in situ, using excitation and emission wavelengths at 466 nm and 516 nm, respectively. Fluoresceinamine, the pH sensitive fluorescent dye, is covalently bonded onto the treated quartz substrate to form a single dye layer. Poly(hydroxystyrene) (Mn equals 13k, Tg equals 180 degrees Celsius) in PGMEA (5% - 18% by weight) is spin cast onto this quartz substrate to form films with varying thickness. The soft bake time is 60 seconds at 90 degrees Celsius and a typical film has a thickness of 1.4 micrometers. Trifluoroacetic acid is introduced into a small chamber while the fluorescence from this quartz window is observed. Our study focuses on finding the diffusion constant of the vaporized acid (trifluoroacetic acid) in the poly(hydroxystyrene) polymer film. By applying the Fick's second law, (It - Io)/(I(infinity ) - Io) equals erfc [L/(Dt)1/2] is obtained. The change of fluorescence intensity with respect to the diffusion time is monitored. The above equation is used for the data analysis, where L represents the film thickness and t represents the average time for the acid to diffuse through the film. The diffusion constant is calculated to be at the order of 10-10 cm2/s to 10-12 cm2/s. All the experiments are conducted at room temperature and are valid only for acid vapor. With different film thickness, it was found that the acid diffuses through the film with a similar diffusion constant. The diffusion is faster with increased solvent residue in the film (controlled by spin coating speed). The theoretical computer modeling of the local acid concentration with respect to acid diffusion is also performed.

Nessas teorias, cujo modelo padro a teoria de Brans-Dicke, a curvatura do espao-tempo, descrita por componentes tensoriais, aparece acoplada a um campo escalar que, de certo modo, representa uma variao na constante de acoplamento da gravitao. Tais teorias apresentam solues locais e cosmolgicas que, em determinados limites, recaem nas apresentadas pela Relatividade Geral, mas que em outros limites trazem novidades, tais como conseqncias observacionais da evoluo de flutuaes primordiais distintas daquelas previstas pela Relatividade Geral (ver, por ex., Nagata et al., PRD 66, p. 103510 (2002)). Graas a esta possibilidade de trazer luz novidades em relao gravitao, teorias do tipo tensor-escalar podem ser vistas como um interessante campo alternativo de pesquisas para solues dos problemas de massa faltante (ou escura) e/ou energia escura. Seguindo tal linha, este trabalho, ainda em sua fase inicial, apresenta solues gerais de teorias do tipo tensor-escalar para diversas situaes, verificando-se em que consiste a divergncia dessas solues dos casos tradicionais poss veis na Relatividade Geral. Como exemplos das solues aqui apresentadas pode-se destacar uma expresso geral para diferentes solues cosmolgicas englobando diferentes tipos de matria (representados por diferentes equaes de estado), e a expresso para uma soluo local representando um buraco negro com rotao, similar soluo de Kerr da Relatividade Geral. Por fim, importante ressaltar que, embora aqui apresentem-se poucos resultados novos, na literatura sobre o assunto a maior parte das solues apresentadas limita-se a uns poucos casos espec ficos, tal como solues cosmolgicas apenas com curvatura nula, e que mesmo as solues dispon veis so, em geral, pouco divulgadas e, portanto, pouco conhecidas, e tal situao que este trabalho busca, em parte, reverter.

A Synchrotron-Based Facility for the in-situ Location, Chemical and Mineralogical Characterization of ~10 um Particles Captured in Aerogel  

SciTech Connect

NASA's Stardust mission collected dust from the coma of Comet Wild-2 on January 2nd, 2004, by direct capture into aerogel cells that flew through the dust coma at 6 km/s. Stardust collected several hundred comet particles >10 {mu}m in size. These comet samples were delivered to Earth on January 15th, 2006. We developed a facility at the National Synchrotron Light Source at Brookhaven National Laboratory (Upton, NY, USA) for the in-situ characterization of 10 {mu}m particles collected in aerogel. These analytical instruments allow us to perform extensive chemical, mineralogical, and size-frequency characterization of particles captured in aerogel. These analyses are conducted without any invasive extraction, minimizing the possibility of contamination or particle loss during preparation. This facility was used to determine the chemical composition, the oxidation state, the mineralogy and to provide an indication of the grain size of the Wild-2 particles before they were removed from the aerogel. This information provides a catalog of particle types, allowing a more reasoned allocation of the particles to subsequent investigators based on a relatively detailed knowledge of the chemical composition and mineralogy of each particle. These measurements allowed a comparison of the chemical and mineralogical properties of the Wild-2 particles with other types of extraterrestrial materials, including interplanetary dust particles and meteorites. The success of in-situ analysis for Wild 2 particles demonstrates that synchrotron-based facilities will be important for the analysis of particles collected in aerogel on future earth-orbiting satellites and spacecraft.

In vivo high-contrast imaging of deep posterior eye by 1-um swept source optical coherence tomography and scattering optical coherence angiography  

NASA Astrophysics Data System (ADS)

Retinal, choroidal and scleral imaging by using swept-source optical coherence tomography (SS-OCT) with a 1-?m band probe light, and high-contrast and three-dimensional (3D) imaging of the choroidal vasculature are presented. This SS-OCT has a measurement speed of 28,000 A-lines/s, a depth resolution of 10.4 ?m in tissue, and a sensitivity of 99.3 dB. Owing to the high penetration of the 1-?m probe light and the high sensitivity of the system, the in vivo sclera of a healthy volunteer can be observed. A software-based algorithm of scattering optical coherence angiography (S-OCA) is developed for the high-contrast and 3D imaging of the choroidal vessels. The S-OCA is used to visualize the 3D choroidal vasculature of the in vivo human macula and the optic nerve head. Comparisons of S-OCA with several other angiography techniques including Doppler OCA, Doppler OCT, fluorescein angiography, and indocyanine green angiography are also presented.

Increased efficiency of silicon light-emitting diodes in a standard 1.2-um silicon complementary metal oxide semiconductor technology  

NASA Astrophysics Data System (ADS)

Scaled versions of a variety of silicon light-emitting diode elements (Si LEDs) have been realized using a standard 1.2- micrometers , double-polysilicon, double-metal, n-well CMOS fabrication process. The devices operated with a n+p junction biased in the avalanche breakdown mode and were realized by using standard features of the ORBIT FORESIGHT design rules. The elements emit optical radiation in a broad band in the 450- to 850-nm range. An emitted intensity of up to 7.1 (mu) W/cm2 has been obtained with 5 mA of current at an operating voltage of 18.5 V. Excellent uniformity in emission intensity of better than 1 percent variation was obtained over areas as large as 100 X 500 micrometers . A best power conversion efficiency of 8.7 X 10-8 and a quantum efficiency of 7.8 X 10-7 were measured. All of these values are about one order of magnitude better than previously reported values for Si LED avalanche devices. Coupling between the elements as well as electro- optical coupling between an element and an optical fiber was realized.

A emisso em 8mm e as bandas de Merrill-Sanford em estrelas carbonadas  

NASA Astrophysics Data System (ADS)

Estrelas carbonadas possuem bandas moleculares em absoro no visvel e, no infravermelho (IR) as principais caractersticas espectrais se devem a emisso de gros. Recentemente foi detectada a presena de bandas de SiC2 (Merrill-Sanford, MS) em emisso sendo atribuda presena de um disco rico em poeira. Neste trabalho analisamos uma amostra de 14 estrelas carbonadas, observadas no telescpio de 1.52 m do ESO em 4 regies espectrais diferentes, a fim de detectar as bandas de MS em emisso. Nossa amostra composta de estrelas que apresentam alm da emisso em 11.3 mm, outra em 8 mm. Esta ltima emisso, no usual nestes objetos, tem sido atribuda ou a molculas de C2H2, ou a um composto slido ainda indefinido. A deteco de emisses de MS e aquelas no IR, simultaneamente, revelaria um cenrio mais complexo que o habitualmente esperado para os ventos destes objetos. No entanto como primeiro resultado, verificamos que as bandas de Merrill-Sanford encontram-se em absoro, no revelando nenhuma conexo com a emisso a 8 mm. Assim, temos duas hipteses: (a) a emisso a 8 mm se deve molcula C2H2 ou (b) essa emisso resultado da emisso trmica de gros. Testamos a segunda hiptese modelando a amostra com gros no-homogneos de SiC e quartzo, o qual emite em aproximadamente 8mm. Este gro seria produzido em uma fase evolutiva anterior a das carbonadas (estrelas S) e por terem uma estrutura cristalina so destrudos apenas na presena de campos de radiao ultravioleta muito intensos. Os modelos para os envoltrios utilizam o mtodo de Monte Carlo para descrever o problema do transporte da radiao. As concluses deste trabalho so: (1) as bandas de Merrill-Sanford se encontram em absoro, sugerindo um cenrio usual para os ventos das estrelas da amostra; (2) neste cenrio, a emisso em 8 mm seria resultado de gros de quartzo com mantos de SiC, indicando que o quartzo poderia sobreviver a fase evolutiva S.

The influence of changes in lifestyle and mercury exposure in riverine populations of the Madeira River (Amazon Basin) near a hydroelectric project.  

PubMed

In the Amazon Basin, naturally occurring methylmercury bioaccumulates in fish, which is a key source of protein consumed by riverine populations. The hydroelectric power-plant project at Santo Antnio Falls allows us to compare the Hg exposure of riverine populations sparsely distributed on both sides of the Madeira river before the area is to be flooded. From 2009 to 2011, we concluded a population survey of the area (N = 2,008; representing circa 80% of community residents) that estimated fish consumption and mercury exposure of riverine populations with different degrees of lifestyle related to fish consumption. Fish samples from the Madeira river (N = 1,615) and 110 species were analyzed for Hg. Hair-Hg was significantly lower (p < 0.001) in less isolated communities near to the capital of Porto Velho (median 2.32 ppm) than in subsistence communities in the Cuni Lake, 180 km from Porto Velho city (median 6.3 ppm). Fish Hg concentrations ranged from 0.01 to 6.06 g/g, depending on fish size and feeding behavior. Currently available fish in the Madeira river show a wide variability in Hg concentrations. Despite cultural similarities, riparians showed hair-Hg distribution patterns that reflect changes in fish-eating habits driven by subsistence characteristics. PMID:24577285

Gold in Archean iron formations at the nova lima district, and in the Quadrilatero Ferrifero, Minas Gerais, Brazil  

SciTech Connect

Gold is in iron formation and metachert of the Rio das Velhas Greenstone Belt which underwent three main periods of deformation and is greenschist facies. At the Morro Velho, Bicalho, Bela Fama, and Urubu mines gold is mostly within and at grain boundaries of pyrrhotite, arsenopyrite, pyrite, minor chalcopyrite, cubanite, tetrahedrite, galena and sphalerite, in stratiform and stratabound massive and banded sulfide bodies. Some gold is in minor quartz veins. The main host rock consist of schistose to massive quartz ferroan dolomite and ankerite and it rests on spilitized tholeiitic metabasalt with intercalcated mafic to felsic metatuffs overlain by intermediate to felsic metatuffs. /sup 18/O of authigenic quartz of 17.07 per thousand is similar to that of Archean marine carbonate-bearing chert. At the Raposos, Faria, Cuiaba, Sao Bento and Santa Quiteria mines gold is with sulfide minerals similar to those at Morro Velho Mine but is in banded, cabonate, silicate, oxide and sulfide facies iron formation conformable upon and lateral to carbonate rock which both overlies and is intercalated with spilitized pillowed metabasalt, felsic metatuffs and graphitic phyllite. Both gold bearing-sections have a base of metamorphosed periodtitic komatiite and basalt and clastic rocks. The gold-bearing sulfide bodies, the carbonate rock and the BIF are interpreted as chemical precipitants on the sea floor by mixing of ascending reduced hot aqueous fluids and sea water.

The orchid-bee fauna (Hymenoptera: Apidae) of a forest remnant in the southern portion of the Brazilian Amazon.  

PubMed

The orchid-bee fauna of the region of Porto Velho, in the state of Rondnia, Brazil, close to the southernmost limits of the Amazon Basin, was surveyed for the first time using five different scents as baits to attract orchid-bee males. Five hundred and twenty-one males belonging to five genera and 29 species were collected with bait traps during 26 non-consecutive days from November, 2011 to January, 2012. Eulaema nigrita Lepeletier, 1841 and Eulaema meriana (Olivier, 1789) were the most common species in the region and, together, represented almost 50% of all collected bees. Although the observed richness conforms to similar inventories in the region, the diversity (H'= 2.43) found in the present study is one of the highest ever recorded for orchid bees in the Amazon Basin.

Elevated mercury concentrations in soils, sediments, water, and fish of the Madeira River basin, Brazilian Amazon: a function of natural enrichments?  

PubMed

Previous site-specific investigations have found that mercury concentrations in water, sediments, and biota of the Brazilian Amazon are elevated above global averages, and that these concentrations are a direct result of widespread mercury amalgamation mining operations conducted by non-organized prospectors. In order to assess the regional impacts of Hg contamination from these non-organized gold mining activities, water, sediments, and fish were systematically collected in 1997 along a 900-km reach of the Madeira River. The sampling program extended from the Amazon River upstream to Porto Velho, the site of historic and ongoing mercury amalgamation mining. Mercury concentrations were found to be elevated above global averages in all sampled media. However, the geochemical data suggest that the high mercury levels are due largely to natural sources and natural biogeochemical processes, and that the impacts of anthropogenically released mercury from mine sites is relatively localized.

Identifing Atmospheric Pollutant Sources Using Artificial Neural Networks  

NASA Astrophysics Data System (ADS)

The estimation of the area source pollutant strength is a relevant issue for atmospheric environment. This characterizes an inverse problem in the atmospheric pollution dispersion. In the inverse analysis, an area source domain is considered, where the strength of such area source term is assumed unknown. The inverse problem is solved by using a supervised artificial neural network: multi-layer perceptron. The conection weights of the neural network are computed from delta rule - learning process. The neural network inversion is compared with results from standard inverse analysis (regularized inverse solution). In the regularization method, the inverse problem is formulated as a non-linear optimization approach, whose the objective function is given by the square difference between the measured pollutant concentration and the mathematical models, associated with a regularization operator. In our numerical experiments, the forward problem is addressed by a source-receptor scheme, where a regressive Lagrangian model is applied to compute the transition matrix. The second order maximum entropy regularization is used, and the regularization parameter is calculated by the L-curve technique. The objective function is minimized employing a deterministic scheme (a quasi-Newton algorithm) [1] and a stochastic technique (PSO: particle swarm optimization) [2]. The inverse problem methodology is tested with synthetic observational data, from six measurement points in the physical domain. The best inverse solutions were obtained with neural networks.

Neurodevelopment of Amazonian Infants: Antenatal and Postnatal Exposure to Methyl- and Ethylmercury  

PubMed Central

Neurodevelopment as Gesell development scores (GDSs) in relation to mercury exposure in infants (<6 months of age) of one urban center and two rural villages, respectively, of fisherman and cassiterite miners. Mean total hair-Hg (HHg) concentrations of infants from Itapu (3.95 1.8?ppm) were statistically (P = 0.0001) different from those of infants from Porto Velho (3.84 5.5?ppm) and Bom Futuro (1.85 0.9?ppm). Differences in vaccine coverage among these populations resulted in significantly higher (P = 0.0001) mean ethylmercury (EtHg) exposure in urban infants (150??g) than in infants from either village (41.67??g, Itapu; 42.39??g, Bom Futuro). There was an inverse significant (Spearman r = ?0.2300; P = 0.0376) correlation between HHg and GDS for infants from Porto Velho, but not for the rural infants from Bom Futuro (Spearman r = 0.1336; P = 0.0862) and Itapu (Spearman r = 0.1666; P = 0.5182). Logistic regression applied to variables above or below the median GDS showed that EtHg exposure (estimated probability = ?0.0157; P = 0.0070) and breastfeeding score (estimated probability = ?0.0066; P = 0.0536) score were significantly associated with GDS. Conclusion. In nurslings whose mothers are exposed to different levels of fish-MeHg (HHg), a higher score of neurological development at six months was negatively associated with exposure to additional TCV-EtHg. Results should be interpreted with caution because of unaccounted variables. PMID:22619491

The molecular beam epitaxy growth and characterization of zinc cadmium selenide/zinc cadmium magnesium selenide-indium phosphide quantum cascade structures for operation in the 3 - 5 um range  

NASA Astrophysics Data System (ADS)

The quantum cascade (QC) laser has captured the interest of researchers for almost three decades. In the early stages, researchers were very interested in proving the QC concept1 proposed by Kazarinov and Suris in 1971. This new concept gave researchers hope that very bulky energy inefficient infra-red (IR) lasers would be replaced with ones that are very compact, tunable and portable. Since the proposal of the QC laser concept and its first demonstration by researchers at Bell Laboratories2 in 1994, this technology has progressed to the point where it is now finding commercial applications in a variety of areas such as military counter measures, free space telecommunications, infra-red imaging and chemical spectroscopy.3-5 The success of this technology can be attributed to the coming of age of the techniques of molecular beam epitaxy (MBE) semiconductor growth and bandgap engineering. 6,7 Using MBE technology, the temperature of the source material can be stabilized by making use of a combination of proportional integral derivative (PID) controllers and thermocouple feedbacks. As a result, the material flux from the effusion cells can achieve stability better than (+/-) 1%. This flux stability together with a well-developed computer controlled shuttering mechanism make it possible to grow multi-quantum well (MQW) structures with excellent layer thickness precision (mono-layer scale) and interface quality. This stringent control of material flux is also a tool that is used by MBE growers to vary the material compositions for the growth of lattice matched and strain compensated QC structures. Today, MBE stands out as one of the premier methods for growing high performing QC lasers. The first successful demonstration of a QC laser2 was done using the InGaAs/InAlAs-InP material system. This demonstration was then repeated a few years later using GaAs/AlGaAs-InP.8 These III-V material systems were extensively studied to establish their material parameters. Given that material parameters are critically important in the process of modeling QC structures, it is not surprising that early success was achieved using these systems. Today, the best performing QC lasers operate in the 4--13 mum range and are produced using lattice matched InGaAs/InAlAs-InP. In order to produce short wavelength QC lasers, the well layer thicknesses in the active region of the device must be reduced in an effort to push the lasing energy states further apart. This reduction in well thicknesses results in the movement of the upper lasing state closer to the bandedge. This action increases the probability of the lost of lasing state electrons to the continuum. Therefore, in order to produce high performing short wavelength QC lasers, a large conduction band offset (CBO) is required. The CBO of lattice matched InGaAs/InAlAs-InP is 0.52 eV. In an attempt to produce high performing devices below 4 mum many researchers have resorted to the use of strain compensation9-11 . This approach has yielded very little improvement in performance due to electron scattering to the X and L intervalleys. This has lead to the exploration of wide bandgap material systems such as the antominides and nitrides. In this work the wide bandgap II-V Znx'Cd(1-x')Se/Zn xCdyMg(1-x-y)Se-InP will be explored for QC laser fabrication. To this end, QC lasers were designed for operation at 3--5 mum range. A Matlab-based program was written to calculate the energy level spacing within the active region of these devices. This simulation program was based on Schroindger's equation and the transfer matrix technique. Several calibration samples were grown to establish the doping levels and growth rate of the well and barrier materials. The growth rate was measured using scanning electron microscopy (SEM) and reflection high energy electron diffraction (RHEED) oscillations during MBE growth. X-ray diffraction measurements were performed to determine the lattice mismatch of the II-VI bulk layers, and therefore predict whether material composition adjustments were required to attain the lattice

Spectral reflectance properties (0.4-2.5 um) of secondary Fe-oxide, Fe-hydroxide, and Fe-sulfate-hydrate minerals associated with sulfide-bearing mine waste  

USGS Publications Warehouse

Fifteen Fe-oxide, Fe-hydroxide, and Fe-sulphate-hydrate mineral species commonly associated with sulphide bearing mine wastes were characterized by using X-ray powder diffraction and scanning electron microscope methods. Diffuse reflectance spectra of the samples show diagnostic absorption features related to electronic processes involving ferric and/or ferrous iron, and to vibrational processes involving water and hydroxyl ions. Such spectral features enable field and remote sensing based studies of the mineral distributions. Because secondary minerals are sensitive indicators of pH, Eh, relative humidity, and other environmental conditions, spectral mapping of these minerals promises to have important applications to mine waste remediation studies. This report releases digital (ascii) spectra (spectral_data_files.zip) of the fifteen mineral samples to facilitate usage of the data with spectral libraries and spectral analysis software. The spectral data are provided in a two-column format listing wavelength (in micrometers) and reflectance, respectively.

Mid- to Far-Infrared spectroscopy of Sharpless 171  

E-print Network

We have collected one-dimensional raster-scan observations of the active star-forming region Sharpless 171 (S171), a typical HII region-molecular cloud complex, with the three spectrometers (LWS, SWS, and PHT-S) on board ISO. We have detected 8 far-infrared fine-structure lines, [OIII] 52um, [NIII] 57um, [OI] 63um, [OIII] 88um, [NII] 122um, [OI] 146um, [CII] 158um, and [SiII] 35um together with the far-infrared continuum and the H2 pure rotation transition (J=5-3) line at 9.66um. The physical properties of each of the three phases detected, highly-ionized, lowly-ionized and neutral, are investigated through the far-infrared line and continuum emission. Toward the molecular region, strong [OI] 146um emission was observed and the [OI] 63um to 146um line ratio was found to be too small (about 5) compared to the values predicted by current photodissociation region (PDR) models. We examine possible mechanisms to account for the small line ratio and conclude that the absorption of the [OI] 63um and the [CII] 158um emission by overlapping PDRs along the line of sight can account for the observations and that the [OI] 146um emission is the best diagnostic line for PDRs. We propose a method to estimate the effect of overlapping clouds using the far-infrared continuum intensity and derive the physical properties of the PDR. The [SiII] 35um emission is quite strong at almost all the observed positions. The correlation with [NII] 122um suggests that the [SiII] emission originates mostly from the ionized gas. The [SiII] 35um to [NII] 122um ratio indicates that silicon of 30% of the solar abundance must be in the diffuse ionized gas, suggesting that efficient dust destruction is undergoing in the ionized region.

Nontuberculous mycobacteria in respiratory samples from patients with pulmonary tuberculosis in the state of Rondnia, Brazil  

PubMed Central

The main cause of pulmonary tuberculosis (TB) is infection with Mycobacterium tuberculosis (MTB). We aimed to evaluate the contribution of nontuberculous mycobacteria (NTM) to pulmonary disease in patients from the state of Rondnia using respiratory samples and epidemiological data from TB cases. Mycobacterium isolates were identified using a combination of conventional tests, polymerase chain reaction-based restriction enzyme analysis of hsp65 gene and hsp65 gene sequencing. Among the 1,812 cases suspected of having pulmonary TB, 444 yielded bacterial cultures, including 369 cases positive for MTB and 75 cases positive for NTM. Within the latter group, 14 species were identified as Mycobacterium abscessus, Mycobacterium avium, Mycobacterium fortuitum, Mycobacterium intracellulare, Mycobacterium gilvum, Mycobacterium gordonae, Mycobacterium asiaticum, Mycobacterium tusciae, Mycobacterium porcinum, Mycobacterium novocastrense, Mycobacterium simiae, Mycobacterium szulgai, Mycobacterium phlei and Mycobacterium holsaticum and 13 isolates could not be identified at the species level. The majority of NTM cases were observed in Porto Velho and the relative frequency of NTM compared with MTB was highest in Ji-Paran. In approximately half of the TB subjects with NTM, a second sample containing NTM was obtained, confirming this as the disease-causing agent. The most frequently observed NTM species were M. abscessus and M. avium and because the former species is resistant to many antibiotics and displays unsatisfactory cure rates, the implementation of rapid identification of mycobacterium species is of considerable importance.

Pego do Diabo (Loures, Portugal): Dating the Emergence of Anatomical Modernity in Westernmost Eurasia  

PubMed Central

Background Neandertals and the Middle Paleolithic persisted in the Iberian Peninsula south of the Ebro drainage system for several millennia beyond their assimilation/replacement elsewhere in Europe. As only modern humans are associated with the later stages of the Aurignacian, the duration of this persistence pattern can be assessed via the dating of diagnostic occurrences of such stages. Methodology/Principal Findings Using AMS radiocarbon and advanced pretreatment techniques, we dated a set of stratigraphically associated faunal samples from an Aurignacian IIIIV context excavated at the Portuguese cave site of Pego do Diabo. Our results establish a secure terminus ante quem of ca.34,500 calendar years ago for the assimilation/replacement process in westernmost Eurasia. Combined with the chronology of the regional Late Mousterian and with less precise dating evidence for the Aurignacian II, they place the denouement of that process in the 37th millennium before present. Conclusions/Significance These findings have implications for the understanding of the emergence of anatomical modernity in the Old World as a whole, support explanations of the archaic features of the Lagar Velho child's anatomy that invoke evolutionarily significant Neandertal/modern admixture at the time of contact, and counter suggestions that Neandertals could have survived in southwest Iberia until as late as the Last Glacial Maximum.

The impacts of land use changes in the mercury flux in the Madeira River, Western Amazon.  

PubMed

Changes in hydrochemistry and Hg distribution in the Madeira River from Porto Velho to the confluence with the Amazon River were studied in two cruises in 1997 and 2002. Water conductivity was similar in both periods, but the pH was significantly higher in 2002, in particular along the middle reaches of the river. Total suspended matter concentrations also increased from 1997 to 2002 along the same river portion, which is a result of forest conversion to other land uses, in particular pastures and agriculture accelerated during the interval between the cruises. Dissolved Hg concentrations were similar along the river in both cruises, but particulate Hg concentrations increased significantly along the middle portion of the river, although the suspended matter from 2002 was relatively poorer in Hg compared to that from 1997. Since particulate Hg represents more than 90% of the total Hg present in the river water, there was a significant increase in the total Hg transport in the Madeira River. Although gold mining has nearly ceased to exist in the region, the remobilization of Hg from forest soils through conversion to other land uses is responsible for maintaining relatively high Hg content in the Madeira River environment.

The decline of Dom Pedro II's empire and health: neuropathogenic implications.  

PubMed

The main objective of this paper is to know the medical doctors of the Emperor, the preconized treatment, and the knowledge about diabetes at that time, its repercussions on the Emperor's nervous system, and the related political implications. A narrative revision was made, based on primary and secondary sources. Dom Pedro II was examined by the aristocracy of the medicine at the time, especially Jean-Martin Charcot, amongst the doctors of international reputation, and Cludio Velho da Motta Maia, amongst the Brazilian doctors. Charcot diagnosed in the Monarch: mental stress, diabetic neuropathy, and a cerebral vascular lesion, probably a stroke, that he differentiated from other vascular obliterations elsewhere. He demonstrated his knowledge about diabetic neuropathy, possible topographical alternatives to justify the urinary incontinence, and Dom Pedro's weakness in the legs. Throughout his illness, Dom Pedro II presented others manifestations that contributed to his physical fragility, and that, certainly too, to his political decline, deposition and the proclamation of the Brazilian Republic.

Clinical Outcomes in Patients with Intermediate Coronary Stenoses: MINIATURE Investigators (Korea MultIceNter TrIal on Long-Term Clinical Outcome According to the Plaque Burden and Treatment Strategy in Lesions with MinimUm Lumen ARea lEss Than 4 mm2 Using Intravascular Ultrasound)  

PubMed Central

Background and Objectives We evaluated the two-year clinical outcomes in patients with angiographically intermediate lesions according to the plaque burden and treatment strategy. Subjects and Methods We prospectively enrolled patients with angiographically intermediate lesions (diameter stenosis 30-70%) with an intravascular ultrasound (IVUS) minimum lumen area (MLA) <4 mm2 with 50-70% plaque burden of 16 Korean percutaneous coronary intervention centers. Patients were divided into medical therapy group (n=85) and zotarolimus-eluting stent group (ZES; Resolute) group (n=74). We evaluated the incidences of two-year major adverse cardiovascular events (MACE). Results A two-year clinical follow-up was completed in 143 patients and MACE occurred in 12 patients. There were no significant differences in the incidences of death (1.3% vs. 3.0%, p=0.471), target vessel-related non-fatal myocardial infarction (0.0% vs. 0.0%, p=1.000) and target vessel revascularizations (7.8% vs. 4.5%, p=0.425) between medical and ZES groups. Independent predictors of two-year MACE included acute myocardial infarction {odds ratio (OR)=2.87; 95% confidence interval (CI) 1.43-6.12, p=0.014}, diabetes mellitus (OR=2.46; 95% CI 1.24-5.56, p=0.028) and non-statin therapy (OR=2.32; 95% CI 1.18-5.24, p=0.034). Conclusion Medical therapy shows comparable results with ZES, and myocardial infarction, diabetes mellitus and non-statin therapy were associated with the occurrence of two-year MACE in patients with intermediate lesion with IVUS MLA <4 mm2 with 50-70% of plaque burden.

Isolation and characterization of genetic variability in bacteria with ?-hemolytic and antifungal activity isolated from the rhizosphere of Medicago truncatula plants.  

PubMed

In the present study, we analyzed the frequency of hemolytic and antifungal activities in bacterial isolates from the rhizosphere of Medicago truncatula plants. Of the 2000 bacterial colonies, 96 showed ?-hemolytic activities (frequency, 4.8 x 10(-2)). Hemolytic isolates were analyzed for their genetic diversity by using random amplification of polymorphic DNA, yielding 88 haplotypes. The similarity coefficient of Nei and Li showed a polymorphic diversity ranging from 0.3 to 1. Additionally, 8 of the hemolytic isolates showed antifungal activity toward plant pathogens, Diaporthe phaseolorum, Colletotrichum acutatum, Rhizoctonia solani, and Fusarium oxysporum. The 16S ribosomal sequencing analysis showed that antagonistic bacterial isolates corresponded to Bacillus subtilis (UM15, UM33, UM42, UM49, UM52, and UM91), Bacillus pumilus (UM24), and Bacillus licheniformis (UM88). The present results revealed a higher genetic diversity among hemolytic isolates compared to that of isolates with antifungal action. PMID:25062484
