LASER WELDING OF TITANIUM ALLOY TI 6 AL 4 V USING A DISK LASER Assist

Study of butt joints welding of titanium alloy sheets Ti6Al4V (Grade 5 according to ASTM B265) using a new generation disk laser TRUMPF TRUDISK 3302 were carried out, and the results are presented in this paper. Butt joints of the titanium alloy sheets 2,0 mm thick were laser welded without an additional material at a flat position, using a specially designed system for shielding gas (high purity argon). The influence of laser welding parameters on weld quality and mechanical properties of test joints was studied. The quality and mechanical properties of the joints were determined by means of tensile and bending tests, hardness and micro hardness tests, and also metallographic examinations.

Re-estimating the Size of the Polar Bear Population in Western Hudson Bay

A mark-recapture study of polar bears ( Ursus maritimus ) ashore during the ice-free period of Hudson Bay was undertaken in 1994 and 1995 to re-estimate the size of the western Hudson Bay population. Previous estimates were based on animals caught between the Churchill and Nelson Rivers; consequently, bears in the southern part of the geographic range of this population were not sampled. We used Jolly-Seber models to re-estimate population size from two data sets: bears handled between the Churchill and Nelson Rivers from 1984 to 1995 and bears handled between Churchill and the Manitoba-Ontario border from 1984 to 1986 and by us in 1994 and 1995. Both data sets gave similar estimates. Thus, our best estimate of the size of the western Hudson Bay polar bear population is 1200 ±250 animals in autumn 1995. Key words: population estimates, population models, polar bear, Ursus maritimus , Manitoba, Ontario
Decadal simulation and comprehensive evaluation of CESM/CAM5.1 with advanced chemistry, aerosol microphysics, and aerosol‐cloud interactions

Earth system models have been used for climate predictions in recent years due to their capabilities to include biogeochemical cycles, human impacts, as well as coupled and interactive representations of Earth system components (e.g., atmosphere, ocean, land, and sea ice). In this work, the Community Earth System Model (CESM) with advanced chemistry and aerosol treatments, referred to as CESM‐NCSU, is applied for decadal (2001–2010) global climate predictions. A comprehensive evaluation is performed focusing on the atmospheric component—the Community Atmosphere Model version 5.1 (CAM5.1) by comparing simulation results with observations/reanalysis data and CESM ensemble simulations from the Coupled Model Intercomparison Project phase 5 (CMIP5). The improved model can predict most meteorological and radiative variables relatively well with normalized mean biases (NMBs) of −14.1 to −9.7% and 0.7–10.8%, respectively, although temperature at 2 m (T2) is slightly underpredicted. Cloud variables such as cloud fraction (CF) and precipitating water vapor (PWV) are well predicted, with NMBs of −10.5 to 0.4%, whereas cloud condensation nuclei (CCN), cloud liquid water path (LWP), and cloud optical thickness (COT) are moderately‐to‐largely underpredicted, with NMBs of −82.2 to −31.2%, and cloud droplet number concentration (CDNC) is overpredictd by 26.7%. These biases indicate the limitations and uncertainties associated with cloud microphysics (e.g., resolved clouds and subgrid‐scale cumulus clouds). Chemical concentrations over the continental U.S. (CONUS) (e.g., SO42− , Cl−, OC, and PM2.5) are reasonably well predicted with NMBs of −12.8 to −1.18%. Concentrations of SO2, SO42− , and PM10 are also reasonably well predicted over Europe with NMBs of −20.8 to −5.2%, so are predictions of SO2 concentrations over the East Asia with an NMB of −18.2%, and the tropospheric ozone residual (TOR) over the globe with an NMB of −3.5%. Most meteorological and radiative variables predicted by CESM‐NCSU agree well overall with those predicted by CESM‐CMIP5. The performance of LWP and AOD predicted by CESM‐NCSU is better than that of CESM‐CMIP5 in terms of model bias and correlation coefficients. Large biases for some chemical predictions can be attributed to uncertainties in the emissions of precursor gases (e.g., SO2, NH3, and NOx) and primary aerosols (black carbon and primary organic matter) as well as uncertainties in formulations of some model components (e.g., online dust and sea‐salt emissions, secondary organic aerosol formation, and cloud microphysics). Comparisons of CESM simulation with baseline emissions and 20% of anthropogenic emissions from the baseline emissions indicate that anthropogenic gas and aerosol species can decrease downwelling shortwave radiation (FSDS) by 4.7 W m−2 (or by 2.9%) and increase SWCF by 3.2 W m−2 (or by 3.1%) in the global mean.
Phylogenetic relationships of Romanian cattle to other cattle populations determined using mitochondrial DNA D-Loop sequence variation.

Phylogenetic relationships of Romanian cattle breeds to various other cattle breeds including Bos taurus, Bos indicus (Indian zebu), Bison bison and Bison bonasus were assessed using mtDNA Dloop sequences. Kimura's two-parameter distances were calculated and a cluster analysis using the Neighbour-joining method was performed to obtain phylogenetic trees among sequences determined and then published in GenBank. The NJ tree showed that Bison bison, Bison bonasus and Bos indicus, respectively, are clearly separate from other cattle breeds. In addition, there are two main distinct genetic lineages: taurine (Bos taurus) and zebu (Bos indicus), that was fully supported by 100% of 1000 bootstrap iterations. The result also indicates that the geographic cattle sequences of taurine lineage are mixed. The conclusion we have reached indicates that the sequences are closely related or have recently diverged.
Consumption of Fruitflow V R lowers blood pressure in pre-hypertensive males : a randomised , placebo controlled , double blind , cross-over study

In order to investigate whether the angiotensin converting enzyme-inhibitory tomato extract FruitflowR would lower blood pressure after consumption, we conducted a randomised, doubleblinded, placebo-controlled human intervention study, involving 12 pre-hypertensive people in a crossover design. Consuming a single dose of 150mg FruitflowR resulted in a significant reduction in 24-hour average blood pressure as well as average wake-period and sleep-period SBP, compared to placebo. Other parameters related to blood pressure, such as 24-hour average mean arterial pressure, pulse pressure, heart rate, central aortic systolic pressure and radial augmentation index were also reduced. In addition, the platelet aggregation response to ADP, measured 24hours after consuming FruitflowR , fell significantly compared to baseline, and compared to placebo. This pilot study clearly shows the beneficial effects of FruitflowR on two important cardiovascular risk factors, high blood pressure and platelet hyperactivity.

Gene expression profile of side population cells in human oral cancer cell line SCC-4

To define the prope rties ot side population {SP} cells of the oral squamous cell carcinoma cel1 line SCC-4, we compared their gene expression profite with that of main population (MP) cells, SP cells accounted for approximately 1.5% of the cell population, The gene expression profile in SP cells versus MP cells revealed that 15.8% of genes were up-regulated by more than 10%, and 16.6% were down-regulated by more than 10%. Gene Ontology and KEGG pathway enrichment analyses were carried out on the DAVID online toot for 26,879 distinct probes (p<O.05). The terms involved in immunetinflammatory responses, cell migration and angiogenesis were detected as up-regulated genes. The terms related to DNA replicatien, DNA metabolic process, mismatch repair and base excretion repair were detected as
Blue Or Red? Exploring the Effect of Color on Cognitive Performance

Existing research reports inconsistent findings with regards to the effect of color on performance in cognitive tasks. While some research suggests that cool colors (i.e., blue/green) lead to better performances than warm colors (i.e., red), others record the opposite. We reconcile this discrepancy by demonstrating that different colors can activate alternative regulatory focus and consequently enhance performances on different types of cognitive tasks. Specifically, we show that while red induces a prevention focus and consequently enhances performance on detail-oriented tasks, blue activates a promotion focus and thus enhances performance on creative tasks. Implications for consumer behavior are demonstrated.
DETECTION , TRACKING AND COMMUNICATION BETWEEN TWO ROBOTS Student : Sonda

Mobile robot Detection and tracking is an important and challenging problem in the area of computer vision. In this context fits our project which presents a target-tracking system for mobile robots realized with two robots, one robot acts as a moving target and the other plays the role of a tracker. The proposed algorithm includes two main steps: robot detection and robot tracking. Robot detection is based on the Gabor filter for robot feature extraction and the Support Vector Machine (SVM) classifier. The concept of tracking robot is realized once the robot detection is accomplished using the Kalman filter. The ZigBee technology is, also, used for the communication between the two robots .
Sensitivity of the Dynamic Response of Monopile-Supported Offshore Wind Turbines to Structural and Foundation Damping

The prediction of ultimate and fatigue demands for the design of offshore wind turbines (OWTs) requires accurate simulation of the dynamic response of OWTs subject to time-varying wind and wave loads. The magnitude of damping in an OWT system significantly influences the dynamic response, however, some sources of damping, such as foundation damping, are not explicitly considered in design guidelines and may increase damping significantly compared to commonly assumed values in design. Experimental and analytical studies have estimated the magnitude of foundation damping to be between 0.17% and 1.5% of critical, and this paper investigates how increased damping within this range affects load maxima and fatigue damage for a hypothetical 5MW OWT subjected to a variety of wind, wave, and operational conditions. The paper shows that increased damping effects the greatest percentage reduction of ultimate moment demands and fatigue damage when the OWT rotor is parked and feathered. In such cases, the aerodynamic damping is relatively low, allowing for additional damping from the foundation to account for a relatively larger proportion of the total system damping. Incorporating foundation damping in design guidelines may lead to more efficient structures, which is a crucial factor in overcoming the high cost barrier associated with offshore wind development.
EFFECT OF SOME PLANT EXTRACTS ON CITRUS MEALY BUG PLANOCOCCUS CITRI ( RISSO )

Pulp of sour orange fruit; Citrus aurantium v. amara extracted in water and petroleum ether, leaves of lantana; Lantana salvifolia extracted in acetone and leaves of Herb Robert; Geranium robertianum extracted in water at different concentrations 3, 4 and 5% were tested under laboratory conditions against Citrus mealy bug Planococcus citri (Risso) (Pseudococcidae: Homoptera) which is one of the most wide spread insects infesting horticulture crops either inside or outside greenhouses. Data demonstrated that sour orange extracted in petroleum ether the highest reduction in the population of the different stages of the mealy bug being 97.01% after 8 days from treatment with the assayed materials at 5% concentration. While lantana extract in acetone, pulp of sour orange and leaves of Herb Robert extracted in water achieved intermediate reductions in bug population. Also, LT50 values were determined for the different treatments and it ranged from 2.32 to 3.75 days for leaves of Herb Robert extracted in water and pulp of sour orange extracted in water, respectively.
Rabbits killing birds: modelling the hyperpredation process

1. Introduced rabbits are known to have catastrophic effects on oceanic islands, either by direct destruction of the vegetative cover, or by the resulting disturbance of indigenous vertebrates. 2. Another dramatic effect, less well known, but potentially of major importance, is the hyperpredation process. This process, related to apparent competition, predicts that an introduced prey species, well adapted to high predation pressure, could induce the extinction of an indigenous prey, through the sudden increased population size of an introduced predator. In many island ecosystems, the simultaneous presence of introduced feral cats and rabbits is thus potentially a further threat for small vertebrates endemic of these islands. 3. Through a mathematical model, we tested this hypothesis, using a tri-trophic system comprising an indigenous prey (birds), an introduced prey (rabbits) and an introduced predator (cats), and we demonstrated the theoretical existence of the hyperpredation process. 4. In addition, the numerical analysis of the model allowed a quantification of this process. It shows that the conditions required for an indigenous species to cope with the hyperpredation process imply very high intrinsic growth rates and/or carrying capacity, as well as behavioural anti-predator response to the introduced predator. Since these conditions are unlikely to be met, this process is a further potential threat to most indigenous vertebrate prey. 5. Finally, our model shows that, although it can be induced by both types of adaptation together or alone, behavioural adaptations alone are more powerful in generating the hyperpredation process, than are life history traits adaptations.
The Costs of Being Wrong about Lags in Monetary Policy

This paper examines the losses associated with conducting monetary policy based upon an incorrect estimate of the delay between a change in policy and subsequent changes in macroeconomic variables. The paper finds that the costs of overestimating or underestimating the delay depend upon the particular loss function over outcomes for inflation and output used to evaluate policy. When inflation variability is weighted heavily in the loss function, it is less costly to assume the policy delay is too long than it is to assume the delay is too short. However, when output variation is sufficiently important in the loss function the results reverse and if an error is made, it is better to assume the delay is too short rather than too long. Finally, when the weight on output variation is large enough, it can be optimal to conduct policy as though the delay is short even if it is known that the true delay is longer.

Calibration of HEC-RAS Model on Prediction of Flood for Lower Tapi River, India

Channel roughness is a sensitive parameter in development of hydraulic model for flood forecasting and flood inundation mapping. The requirement of multiple channel roughness coefficient Mannnig’s ‘n’ values along the river has been spelled out through simulation of floods, using HEC-RAS, for years 1998 and 2003, supported with the photographs of river reaches collected during the field visit of the lower Tapi River. The calibrated model, in terms of channel roughness, has been used to simulate the flood for year 2006 in the river. The performance of the calibrated HEC-RAS based model has been accessed by capturing the flood peaks of observed and simulated floods; and computation of root mean squared error (RMSE) for the intermediated gauging stations on the lower Tapi River.
Need and utilization of primary health care among long-term unemployed Finns

Introduction: Aim of this paper was to identify the attributes of primary health care utilization among long-term unemployed Finns, and to examine whether access to care and the choice of provider differ with respect to employment status. Methods: Data on primary health care utilization were derived from two sources; a targeted questionnaire about the use of services and quality of life among long-term unemployed individuals, and the Welfare and Services in Finland Survey, covering the general population. A two-part econometric model was applied in order to separate between the probability and level of utilization. The statistical analysis allowed predicting the monetary costs of primary care utilization. In this context, a non-parametric smearing factor was used to adjust for retransformation bias. In addition, a distinction between the level of costs and number of visits was taken to account for the effect of unit cost variation. Results: The analyses indicated that the utilization of primary health care services among the long-term unemployed varied with respect to gender, self-rated health status and economic situation, place of residence, marital status and duration of unemployment. The scope of analysis was shown to be fundamental for the interpretation of the comparative results. Taking into account the provision of occupational care services inverted the positive effect of long-term unemployment on primary care utilization. Further, while the costs of utilization were independent of employment status, long-term unemployment had a distinct reducing effect on the number of medical visits. Discussion and Conclusion: Despite of greater health care needs, the long-term unemployed sought less visits to more costly public primary care services. In order to confront unmet health care needs among the long-term unemployed, public sector interventions should be targeted accordingly, and in particular, involve gender specific social marketing measures.

Fatty acid methyl esters produced by oleaginous yeast Yarrowia lipolytica QU21: an alternative for vegetable oils

Fatty acid methyl esters produced by oleaginous yeast Yarrowia lipolytica QU21: an alternative for vegetable oils. An alternative for vegetable oil is microbial oil. There is, nowadays, an increasing interest in microbial lipidic compounds, called single cell oils (SCO), due to their several potential biotechnological applications, such as biodiesel production, food ingredients and antimicrobial activity, among others. Oleaginous yeasts are able to accumulate lipids up to 20% of their cellular dry weight, and some species can accumulate up to 70% of lipids. We have screened 86 yeast strains isolated from artisanal cheese using Nile red stain for the detection of intracellular lipid droplets by fluorescence microscopy, and 27% of them were promising for the production of microbial oil. Yarrowia lipolytica QU 21 was selected for comparison of five different methods of cell wall disruption for lipid extraction at a laboratory scale (dry biomass maceration, lysis with vortex and glass beads, ultrasonic bath and glass beads, maceration using liquid nitrogen, and liquid nitrogen followed by sonication). The method which showed the highest oil yield value (36%) was liquid nitrogen with sonication. Oil yield was highly influenced by the method used for cell wall lysis. Fatty acid methyl esters (FAME) composition of strain QU 21 after GC analysis was myristic acid (C14:0), myristoleic acid (C14:1), palmitic acid (C16:0), palmitoleic acid (C16:1), heptadecanoic acid (C17:1), stearic acid (C18:0) and oleic acid (C18:1).
Improved Quantum Circuits with Qudits and Dirty Ancillae

Architectural research has made significant contributions to the prospects for near-term quantum computation by leveraging techniques such as mapping, scheduling, and parallelism. In this work, we systematically explore two additional techniques that can reduce space (ancillae) and time (circuit depth) requirements by accessing computational resources that are traditionally ignored. The first technique is the use of d-level qudits in favor of the conventional two-level qubit (quantum bit) abstraction. The second technique is the exploitation of dirty ancillae: idle qubits (or qudits) from other parts of computation which can be borrowed with the promise that they will be restored to their original states. We introduce new results for more efficient quantum circuits, particularly for multiply-controlled unitary gates, which are critical for many quantum algorithms. Our ongoing work includes the development of an error model that accounts for the cost of using qudits. We are also building a software framework for synthesizing logic circuits that exploit qudits and dirty ancillae, with the goal of maximizing the amount of useful computation possible.
A syntAx-bAsed distributionAl model for discriminAting between semAntic similArity And AssociAtion

In recent years, distributional semantics has shown a trend towards a deeper understanding of what semantic relatedness is and what it is composed of. This is attested, in particular, by the emergence of new gold standards like SimLex999, WS-Sim and WS-Rel. Evidence from cognitive psychology suggests that humans distinguish between two basic types of semantic relations: category-based similarity and thematic association. The paper presents a distributional model capable of differentiating between these relations, and a dataset consisting of 500 similar and 500 associated pairs of nouns that can be used for evaluation of such models.
A novel method "CHROMagar" for screening vancomycin-resistant enterococci (VRE) isolates

Infection with vancomycin-resistant enterococci (VRE) is reported to be increasing and becoming a problem especially in health care systems with prolonged survival in the environment. In this study, we compared the performance characteristics of CHROMagar with conventional methods for detection of VRE in clinical urine specimens. A total of 7404 urine samples were entered in the study. All specimens were cultured by routine microbiological method and were simultaneously cultured in prepared CHROMagar plate for growth characteristics with positive and negative controls. Susceptibility tests were performed by disk diffusion method as recommended by Clinical Laboratory Standards Institute. We also used E-test minimum inhibitory concentration (MIC) for confirmation of VRE isolates. Total isolation rate was 22.19% of the tested specimens. Enterococcus faecium and Enterococcus faecalis were isolated in 10 (0.13%) and 72 (0.92%) cases, respectively while six were VRE belonging to admitted patients. Analyzed data of VRE cases revealed the results of all three applied methods. The antimicrobial susceptibility testing, E-test and CHROMagar were in agreement in all the six identified VRE cases. The obtained results in the present study indicate that CHROMagar method is easy to use, and is a cost- and time-effective procedure for the isolation of VRE especially in urine specimens.
