Yöntemi ile Optimizasyonu Gasification of Kenaf Hydrolysate and Optimization by Response Surface Methodology

In this study, the effect of temperature, feed flow rate and biomass feed concentration parameters on gasification performance of kenaf biomass hydrolysate using continuous atmospheric catalytic vapour phase (AVPR) reforming system was examined. The effect of experimental parameters on the composition of gas products were investigated using the RSM (Response Surface Methodology) method. One of the greatest advantages of this method that makes it possible to study the effect of gasification efficiency on several experimental parameters by carrying out a few experimental studies. The results showed that temperature was main factor on hydrogen-rich gas production while other parameters (biomass feed concentration, feed flow rate) were secondary. As a result of the optimazition, it was observed that the temperature should be above 295 °C, and the flow rate of 0.30 mL / min for high yield hydrogen.
in Chemically Induced Rat Mammary Tumor Treated with Tamoxifen and Transforming Growth Factor- 1

Background : Tamoxifen (TAM) inhibits the action of estrogen by binding to estrogen receptors, and also has non-estrogen receptor mediated cytostatic activities. Transforming growth factor- 1 (TGF- 1) inhibits the proliferation of many other cell types, such as epithelial, hematopoietic and endothelial cells. Methods : We investigated the effects of tamoxifen on the growth of 7,12-dimethylbenz(a)anthracene (DMBA)-induced rat mammary tumors and the expression of cyclin D1, cyclin E, p21Cip1 , and p27 Kip1 by performing immunohistochemistry and Western blot analysis, and studied whether TGF- 1 injection amplified the effects of TAM. When tumor size reached between 10-15 mm in the largest dimension, the rats were divided into 3 groups: DMBA-control group (n=12), DMBA-TAM group (n=14) and DMBATAM plus TGF- 1 group (n=5). Results : The consecutive administration of TAM markedly decreased the tumor development compared with the DMBA-control group. The DMBA-TAM and DMBA-TAM plus TGF- 1 groups showed decreased expression of bromodexoyuridine, cyclin D1, cyclin E, and p21Cip1 when compared with those of the DMBA-control group. On the other hand, the labeling index of p27 Kip1 was higher in the DMBA-TAM plus TGF- 1 group than in the DMBA-control group. Conclusions : TAM suppresses tumor development, which may be associated with down-expression of cyclin D1 and cyclin E, and overexpression of p27 Kip1 , and addition of TGF- 1 does not influence tumor development treated by TAM.
Towards petascale simulation of atmospheric circulations with soundproof equations

This paper highlights progress with the development of a petascale implementation of general-purpose high-resolution (nonoscillatory) hydrodynamical simulation code EULAG [Prusa et al. 2008, Comput. Fluids37, 1193]. The applications addressed are anelastic atmospheric flows in the range of scales from micro to planetary. The new modeldomain decomposition into a three dimensional processor array has been implemented to increase model performance and scalability. The performance of the new code is demonstrated on the IBM BlueGene/L and Cray XT4/XT5 supercomputers. The results show significant improvement of the model efficacy compared to the original decomposition into a two-dimensional processor array in the horizontal — a standard in meteorological models.
Nonlinear vibration modes of the double tracked road vehicle

Free damped oscillations of a double tracked road vehicle with a nonlinear response of the suspension are considered. A 7-DOF nonlinear model is used to analyze dynamics of the suspension with smooth characteristics. Vibration modes of the system and the corresponding skeleton curves are obtained. Nonlinear vibrations of the quarter-car model are considered for the case of non-smooth characteristics of the shock absorber.
Nano lab-on-chip systems for biomedical and environmental monitoring

In recent years, nano lab-on-chip (NLOC) has emerged as a powerful tool for biosensing and an active area of research particularly in DNA genetic and genetic related investigations. Compared with conventional sensing techniques, distinctive advantages of using NLOC for biomedicine and other related area include ultra-high sensitivity, higher throughput, in-situ monitoring and lower cost. This review aims to summarize recent advancements in two major types of NLOC sensing approaches, label and labelled free NLOC, as well as their biomedical applications. The state-of-the-art on how these sensors interface with nano/microfluidics is then presented and the latest papers in the area summarized and also proposal to develop compact NLOC with four different sensing elements with two different mechanisms, common and separate padding is prospected. Keywords: Nano lab-on-chip, in-situ, nano/microfluidics, sensors, DNA African Journal of Biotechnology Vol. 12(36), pp. 5486-5495
RFID Based Collision-Free Robot Docking in Cluttered Environment

This paper proposes a radio frequency identiflcation (RFID) based collision-free robot docking in cluttered environment. Physical distance estimation sensors are fused to the developed degree of arrival (DOA) guided robot docking system, and collision-avoidance function is implemented based on the vector fleld histogram technique. Additionally, new simple but e-cient DOA flltering algorithm is developed based on the gain control according to the improved robot control algorithm, which enables the robot to move continuously. The experimental results show that the robot can move to target transponder even though the estimated DOA is blocked by obstacles. The success rate does not reach satisfactory level due to the limitation of the employed sensors and collision-avoidance algorithm, but it is proved that the collision-free docking becomes available without any priori map and reference stations.
Characterization of Thaumarchaeota isolated from the Northern Adriatic Sea

Die Entdeckung der in aquatischen und terrestrischen Lebensraumen ubiquitar vorkommenden Ammoniak oxidierenden Thaumarchaeota hat zu einem vermehrten Interesse gefuhrt, deren Physiologie und okologische Funktion besser zu verstehen. Im Rahmen dieser Arbeit wurden die physiologische und genomische Charakterisierung von zwei AOA Spezies der Gattung Nitrosopumilus beschrieben, welche aus den Oberflachengewassern des nordlichen Adriatischen Meeres isoliert wurden. Die Entdeckung von phylogenetisch nah verwandten, jedoch funktionell deutlich unterschiedlichen Vertretern der Gattung Nitrosopumilus in der Nordadria, gibt einen Einblick in die Funktionsvielfalt der marinen Thaumarchaeota und weist auf eine mogliche Nischendifferenzierung zwischen den verschiedenen eng verwandten Arten hin.
The Quebec Convergence and Canadian Life Satisfaction, 1985–2008

De plus en plus de sondages, réalisés par des gouvernements ou des entreprises privées, tentent de mesurer la satisfaction face à la vie, cette mesure étant obtenue grâce à des instruments d’auto-évaluation. Au Canada, de tels sondages n’ont pas été faits de façon systématique au fil des ans, mais les données recueillies depuis 1985, de même que des sondages récents réalisés plusieurs fois selon une même structure, facilitent beaucoup l’analyse que nous pouvons maintenant faire de l’évolution de cette satisfaction dans les diverses régions du pays. Dans cet article, je montre que, depuis 25 ans, la satisfaction face à la vie s’est beaucoup accrue au Québec quand on compare cette province au reste du Canada, et que l’ampleur de cette hausse du bienêtre subjectif est comparable à l’effet qu’aurait la multiplication par trois du revenu moyen des ménages.
Entrepreneurial Growth Aspirations and Familiarity with Economic Development Organizations: Evidence from Canadian Firms

The purpose of this paper is to investigate the relationship between the entrepreneurship ecosystem and the entrepreneur’s willingness to grow. This study is particularly interested in exploring the relationship between entrepreneur’s familiarity with the key economic development organizations in the entrepreneurship ecosystem and the willingness to grow. Several studies have investigated the growth process in small and medium sized enterprises (SMEs) since the case has been made that high growth SMEs contribute to economic growth through job creation. To date, these studies have identified multiple internal and external determinants including their effects on small business growth. There is evidence in the literature that characteristics of the entrepreneurs such as the willingness to grow and the entrepreneur’s network are important factors in growth process. However, the relationship between growth process and the entrepreneur’s networking behavior is yet to be fully understood. Drawing from the entrepreneurship ecosystem literature, the growth process literature and the resource dependence theory, this study uses the business confidence survey from 2011 to 2013, which targeted all businesses across all of Halifax Regional Municipality (HRM) in Nova Scotia, Canada, to explore the relationship between the entrepreneur willingness to grow and the propensity to network with key economic development organizations of the entrepreneurial ecosystem. The findings support the assumption that the proportion of businesses that are willing to grow (i.e. hire additional staff and enter new markets within the next twelve months) is higher for the group of businesses that are familiar with the key economic development organizations than for the group of businesses that are not familiar with them. However, the results are not homogeneous across all populations. Our findings also indicate that the higher the expectation to enter new markets over the next twelve months, the higher the odds to be familiar with the key economic development organizations. Our findings contribute to the literature around the association between networking and small business growth.
Solving k-obnoxious facility location problem on a plane

In this paper k-obnoxious facility location problem has been modeled as a pure planner location problem. Area restriction concept has been incorporated by inducting a convex polygon in the constraints set. A linear programming iterative algorithm for k- obnoxious facility locations has been developed. An upper bound has been incorporated in the algorithm to get the optimal solution. Also the concept of upper bound has reduced the number of linear programming problems to solved in the algorithm. Rectilinear distance norm has been considered as the distance measure as it is more appropriate to the various realistic situations.
Deployment, Foam Rigidization, and Structural Characterization of Inflatable Thin-Film Booms

Detailed investigation of the construction, packaging/deployment, foam rigidL'ation, and structural characterization of polyimide film inflatable booms is described. These structures have considerable potential for use in space with solar concentrat_rs, solar sails, space power systems including solar arrays, and other future missions. Numerous thin-film booms or struts were successfully constructed, inflated, injected with foam, and rigidized. Both solid-section and annular test articles were fabricated, using Kapton polyimide fihn, various adhesives, styrofoam end plugs, and polyurethane pressurized foam. Numerous inflation/deployment experiments were conducted and compared to comput,_r simulations using the MSC/DYTRAN code. Finite element models were developed for several foam-rigidized _truts and compared to modal test results. Several problems encountered in the construction, deployment, and foam injection/ri_::idization process arc described. Areas of difficulty includ_:d inadequate adhesive strength, cracking of the film and air leakage, excessive bending of the structure during deployment, problems with loam distribution and curing properties, and control of foam leakage following injection into the structure. Many of these problems were overcome in the course of the research.
It Takes More Than House Calls: Organizing to Win with a Comprehensive Union-Building Strategy

Excerpt] Until recently, some national and local union leaders still argued that labor should circle the wagons and take care of existing members rather than spend scarce resources on organizing nonunion workers. Today those voices have largely been silenced by the hard numbers of labor's dramatic decline. As expressed in the platform of the new AFL-CIO leadership slate, the American labor movement must "organize at an unprecedented pace and scale. " The question unions face today is no longer whether to make organizing a priority but how that can best be achieved.
Can compliant fault zones be used to measure absolute stresses in the upper crust

[1] Geodetic and seismic observations reveal long-lived zones with reduced elastic moduli along active crustal faults. These fault zones localize strain from nearby earthquakes, consistent with the response of a compliant, elastic layer. Fault zone trapped wave studies documented a small reduction in P and S wave velocities along the Johnson Valley Fault caused by the 1999 Hector Mine earthquake. This reduction presumably perturbed a permanent compliant structure associated with the fault. The inferred changes in the fault zone compliance may produce a measurable deformation in response to background (tectonic) stresses. This deformation should have the same sense as the background stress, rather than the coseismic stress change. Here we investigate how the observed deformation of compliant zones in the Mojave Desert can be used to constrain the fault zone structure and stresses in the upper crust. We find that gravitational contraction of the coseismically softened zones should cause centimeters of coseismic subsidence of both the compliant zones and the surrounding region, unless the compliant fault zones are shallow and narrow, or essentially incompressible. We prefer the latter interpretation because profiles of line of sight displacements across compliant zones cannot be fit by a narrow, shallow compliant zone. Strain of the Camp Rock and Pinto Mountain fault zones during the Hector Mine and Landers earthquakes suggests that background deviatoric stresses are broadly consistent with Mohr-Coulomb theory in the Mojave upper crust (with μ ≥ 0.7). Large uncertainties in Mojave compliant zone properties and geometry preclude more precise estimates of crustal stresses in this region. With improved imaging of the geometry and elastic properties of compliant zones, and with precise measurements of their strain in response to future earthquakes, the modeling approach we describe here may eventually provide robust estimates of absolute crustal stress.
QUANTITATIVE ESTIMATION OF GINSENOSIDES IN DIFFERENT AGES OF PANAX VIETNAMENSIS AND THEIR ANTI-PROLIFERATION EFFECTS IN HELA CELLS

Background: The objective of study was to investigate the major compounds of ginsenosides in Panax vietnamensis in its growing stages and their anti-proliferative activity in HeLa cells. Materials and Methods: The roots with different ages were analyzed by HPLC/MS. Anti-proliferation activity of P. Vietnamensis ginseng in HeLa cells was investigated using MTT assay. Results: Three main compounds of ginsenoside, Rb1, Rg1 and majonoside R2 were increased with the increasing of age. However, ginsenoside Rc, Re, Rd and Rg3 did not show any alteration with growing age. The major compound majonoside R2 was accumulated maximum in 5 years old ginseng. According to the data, the anti-proliferation activity was directly proportional to the growing ages of ginseng. The eleven years old ginseng showed maximum effect than the younger roots. This effect may be related to the concentration of ginsenosides or majonoside R2 content in P. Vietnamensis. Conclusion: The concentration of ginsenoside content in the roots of P. Vietnamensis is directly related to the growing ages. Overall, due to the higher concentration of ginsenoside in mature ginseng root, Panax vietnamensis ginseng can be used as an effective anti-proliferative drug.
Genotypic response to regrowth of defoliated sugar beets after re-watering in a water-limited environment : effects on yield and quality

Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of July and then left without irrigation for a month. Three defoliation levels (control-C, moderate-MD and severe-SD) were performed at early August and irrigation was simultaneously started to promote re-growth. Four samplings were conducted (before defoliation, 15, 30 and 40 days after defoliation) to determine the changes in physiological and productive traits. Yields were lower in 2003 compared to 2004 because sugar beets were grown under more stressful conditions due to the delayed sowing, the higher temperatures and the lower rainfall. Both defoliation level and cultivar had significant effects on physiological and productive traits after re-growth only in 2003. The late-season cultivar, Corsica, showed better LAI maintenance compared to Europa and Corsica and had the greatest performance after re-growth in regard to fresh root weight and sugar yield. Also, this cultivar showed the least decrease of sucrose percentage in fresh root weight and juice purity mainly due to the stable potassium (K) concentration and limited increase of sodium (Na) accumulation in roots. Corsica consumed the least root α-amino N for its re-growth. Quantitative and qualitative traits were negatively affected only by the SD treatment. Plants suffered from MD treatment gradually recovered during growing season. This study demonstrates that under Mediterranean conditions, the adverse effects of re-growth on sugar beet yield and quality depend on the growing conditions and they can be restricted by the selection of an appropriate cultivar.
Depressive disorder in rheumatoid arthritis: the more joint’s distressed, the more severely depressed

Introduction: To determine the prevalence of depressive disorder and it's related factors in the patients with rheumatoid arthritis. Methods: This cross-sectional study was conductd from April 2013 to August 2014.A total of 81 patients with Rheumatoid Arthritis (RA) were enrolled from Rheumatology Clinic, Shahid Beheshti Hospital, Kashan/ Iran. The Severety of depressive disorder was measured by Beck Depression Inventory, and the diagnosis of depressive disorder was confirmed in clinical interview by psychiatrist based on DSM-IV-TR. Results: Findings showed that more than half of the RA patients with depression 55.5 % had severe depression, the rest had Moderate and mild degree of depression, (16.7%) and (27.8%) respectively. There was no statistically significant relationship between depression and age, sex, marital status, job, economic status, and joint deformity (P > 0.05). However, the relationship between depression and the number of affected joints was statistically significant (P = 0.02), those patients with seven or more affected joints had a higher rate of depression than those with six or less. Conclusion: Due to the relatively high prevalence of depressive disorder among those patients with rheumatoid arthritis early screening and treatment of depressive disorder is greatly recommended. Declaration of interest: None
An Alternative Model to Radon Transform for Gamma Ray Emission Tomography

The Radon transform fits badly Single Photon Emission Tomography (SPECT). However, Thin Holes Collimator (THC) and Radon model are widely used. The CACAO project has been proposed to enhance the quality of SPECT images. CACAO is a short hand notation for computer aided collimation tomography. The main idea of this project is to use collimators with much larger holes to increase the sensitivity, and slightly longer holes to increase the spatial resolution. The acquisition sequence includes a translation. The Radon projection is replaced by a 2D sum. A dedicated reconstruction algorithm has been developed. If the physical advantage of the project in terms of sensitivity and spatial resolution is generally admitted, a question remains unanswered: Would the ill-posedness of the inverse problem ruin the quality of the reconstructed images? In this article, a representation of the 2D direct problem matrix is derived. This allows us to compare the two inverse problems (CACAO versus THC). The condition number was used for this comparison. We studied the variation of these condition numbers with several parameters. For a proper set of parameters, the CACAO inverse problem may appear easier to solve and more accurately than the THC one.
A unified model for age-velocity dispersion relations in Local Group galaxies: Disentangling ISM turbulence and latent dynamical heating

We analyse age–velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ∼ 106 M⊙) to M31 (M* ∼ 1011 M⊙). Observationally the σ versus stellar age trends can be interpreted as dynamical heating of the stars by giant molecular clouds, bars/spiral arms or merging subhaloes; alternatively the stars could have simply been born out of a more turbulent interstellar medium (ISM) at high redshift and retain that larger velocity dispersion till present day – consistent with recent integral field unit kinematic studies. To ascertain the dominant mechanism and better understand the impact of instabilities and feedback, we develop models based on observed star formation histories (SFHs) of these Local Group galaxies in order to create an evolutionary formalism that describes the ISM velocity dispersion due to a galaxy's evolving gas fraction. These empirical models relax the common assumption that the stars are born from gas that has constant velocity dispersion at all redshifts. Using only the observed SFHs as input, the ISM velocity dispersion and a mid-plane scattering model fits the observed AVRs of low-mass galaxies without fine tuning. Higher mass galaxies above Mvir ≳ 1011 M⊙ need a larger contribution from latent dynamical heating processes (for example minor mergers), in excess of the ISM model. Using the SFHs, we also find that supernovae feedback does not appear to be a dominant driver of the gas velocity dispersion compared to gravitational instabilities – at least for dispersions σ ≳ 25 km s−1. Together our results point to stars being born with a velocity dispersion close to that of the gas at the time of their formation, with latent dynamical heating operating with a galaxy mass-dependent efficiency. These semi-empirical relations may help constrain the efficiency of feedback and its impact on the physics of disc settling in galaxy formation simulations.
Neonatal Abstinence Syndrome Due to Opioid Abuse in Pregnancy

Opioid abuse during pregnancy is increasing in women of childbearing age in Turkey. The frequency of clinical signs of withdrawal in infants who exposed to heroin in utero are varying between 16-90%. Here, we present five newborn infants presenting with neonatal abstinence syndrome who were hospitalized in Neonatal Intensive Care Unit of Mersin Maternity and Children’s Hospital. All of the five infants were symptomatic including irritability, tremors, high-pitched cry, excessive sucking and seizure. Hyperirritability was the predominant sign. Seizure was observed two of the five infants which clinically presented between 1st-5th day of life and was controlled with phenobarbital. We have experienced seizure due to withdrawal of opioid more than the past reports and we thought that interrupting breastfeeding may facilitate seizure. Breastfeeding may slow down the decrease of opioid level in blood and may reduce the symptoms. In conclusion, opioid abuse in pregnancy is a growing sociological problem in Turkey and a protocol for management is required for neonatologists.
