INDIGENOUS VEGETATION OF SOONE VALLEY : AT THE RISK OF EXTINCTION

This paper reports the results of the survey conducted to investigate the eco-geographic factors for in-situ conservation and description of location of various taxonomic and genetic diversity for the provision of critical assistance in the formulation of effective conservation campaign for target plant species near the point of extinction. A survey of the specific valley in mountaineous, region of Pakistan was performed on ten stuffy sites in the valley, selected on the basis of variation in their ecological parameters. Data were assembled on the leguminous plants, but some non-leguminous species were also included to work out frequency, density and coverage / dominance in particular area and status as well as diversity of leguminous plants was determined based on this information. The results obtained on the eco-geographical attributes were discussed in this study in terms of frequency, density, species dominance/percentage as well as relative frequency, relative density and relative coverage/dominance of the given area. A further correlation study with the various attributes regarding different study sites and distribution of species was also counted in this survey. For the effective planning for conservation of precious plant species, it is very essential to get the set of full information about eco-geographical attributes and threatening factors. Therefore the current research survey was conducted to acquire the informations regarding various parameters and threats and adaptations of present species to their environments. Results showed that most observed plant species in this specific valley may be due to some morphological and anatomical as well as physiological adaptations to this environment which is mainly responsible for their survival and perpetuation in this harsh habitat.

Effect of Personality on the Number of Feedback Requests When Learning a Golf-Putting Task

This study examined how personality influences the number of feedback requests and anxiety when learning to putt in golf. Twenty university students (10 males and 10 female) stood in front of a partition and putted a golf ball, with the goal of having the ball stop on a line 3.5 m from the starting position, along a path that included uphill and downhill portions. I used the Japanese version of the Big Five Personality Inventory (Big Five) to evaluate participants’ personalities and the Japanese version of the State-Trait Anxiety Inventory Form (STAI-JYZ) to evaluate participants’ anxiety. After a pretest, participants completed 60 practice trials in which they were allowed to ask how far the ball went if and when they wanted to. All participants then performed a posttest. Results showed that constant error, variable error, and total variability were lower at posttest than pretest. In addition, the results of a multiple regression analysis showed that higher Big Five agreeableness scale and STAI-JYZ anxiety-present scale scores were associated with fewer requests for feedback. These results suggest that the number of feedback requests was related to consideration and awareness, and these findings have implications for future research on cooperation.
Urinary cytology in bladder cancers

A prospective study was done to explore the reliability of urinary cytologic examination of 40 cases of transitional cell carcinoma seen at this institution for the period 1991 to 1993. A specificity of 97% sensitivity of 80%, false negative rate of 12.5% were obtained. A single blind review of cytologic and histologic material from 24 of the cases was also performed for evaluation of the cytologic criteria employed for the grading of tumors. Cythohistologic results of grade 1 lesions was unreliable, whereas the results of grades 2 and 3 lesions were reasonably good. [Turk J Med Res 1994; 12(6): 232-235]
Tolerance potential and physiological responses of Helianthus annuus L. exposed to varying doses of hexavalent chromium

The present investigation assesses the physiological and biochemical response of sunflower plants (Helianthus annuus L.) to increased doses of hexavalent chromium (Cr 6+ ) at different growth periods (15, 30 and 45 days) under in vivo condition. Treatment with 500 mg Cr 6+ /Kg dry soil showed 80% inhibition in Seed germination. The Seedlings after 30 and 45 days of Cr 6+ treatment (100 mg/Kg dry soil) showed negligible difference in their shoot length values, but it was significantly decreased using 200 mg Cr 6+ /Kg dry soil treatment. Notable increase in root length was observed at 50 mg Cr 6+ /Kg soil treatment after 45 days of plant growth. Plant biomass, chlorophyll and carotenoid contents of 45 days treated seedlings were significantly reduced at 200 mg Cr 6+ /Kg soil. The increase in total free amino acid accumulation was noted up to 30 days using different concentrations of Cr 6+ with maximum at 200 mg Cr 6+ /Kg dry soil but on 45 days it showed a decline value with some minor deviations using different concentrations of Cr 6+ . The higher level of Chromium accumulation in shoot in comparison to roots indicates the tolerance potential of H. annuus towards application of toxic doses of hexavalent chromium even through the survival capacity of the plants reduced with increasing Cr 6+ supply. This leads to evolved phytoremediation techniques using in situ application of the plant as a green tool.
Magnetism in thin Cr films grown on Fe(001)-p(1×1)O: a spin-resolved investigation of single and multi-layers

We present a combined experimental and theoretical investigation of the magnetic behavior of ultra-thin Cr films grown on oxygen-passivated Fe(001)-p(1×1)O substrates. In all cases, oxygen floats on the metal/vacuum interface, where a monolayer-range oxide with peculiar electronic and structural characteristics is formed. Significant differences with previous experimental realizations of the Cr/Fe(001) heterostructure are thus introduced by the presence of oxygen. However, we show here that the magnetic behavior of our system is characterized by the same AF stacking at the Cr-Fe interface and by a layer-wise AF order in the Cr layer. In addition, we are able to circumvent the issue of chemical mixing at the Cr-Fe interface, characteristic of standard preparations.
The effects of high versus low talker variability and individual aptitude on phonetic training of Mandarin lexical tones

High variability (HV) training has been found to be more effective than low variability (LV) training when learning various non-native phonetic contrasts. However, little research has considered whether this applies to the learning of tone contrasts. The only two relevant studies suggested that the effect of HV training depends on the perceptual aptitude of participants (Perrachione et al., 2011; Sadakata & McQueen, 2014). The present study extends these findings by examining the interaction between individual aptitude and input variability using natural, meaningful second language input (both previous studies used pseudowords). A total of 60 English speakers took part in an eight session phonetic training paradigm. They were assigned to high/low/high-blocked variability training groups and learned real Mandarin tones and words. Individual aptitude was measured following previous work. Learning was measured using one discrimination task, one identification task and two production tasks. All tasks assessed generalization. All groups improved in both the production and perception of tones which transferred to untrained voices and items, demonstrating the effectiveness of training despite the increased complexity compared with previous research. Although the LV group exhibited an advantage with the training stimuli, there was no evidence for a benefit of high-variability in any of the tests of generalisation. Moreover, although aptitude significantly predicted performance in discrimination, identification and training tasks, no interaction between individual aptitude and variability was revealed. Additional Bayes Factor analyses indicated substantial evidence for the null for the hypotheses of a benefit of high-variability in generalisation, however the evidence regarding the interaction was ambiguous. We discuss these results in light of previous findings.
What Do We Really Know about Corporate Hedging ? A Multimethod Meta-Analytical Study

This paper employs meta-analysis to aggregate and systematically analyze the mixed empirical evidence on the determinants of corporate hedging reported in 132 previously published studies covering data from more than 73,000 firms. Among the fourteen proxy variables analyzed by multivariate meta-analysis, three variables emerge as reliable explanatory factors for corporate hedging decisions supporting the bankruptcy and financial distress hypothesis: dividend yield (positive sign), liquidity (negative sign), and firm size (positive sign). Moreover, for tax-loss carry forwards (positive sign) and research and development (positive sign), our findings indicate a weak impact on corporate hedging behavior reflecting tax reasons, the coordination Electronic supplementary material The online version of this article (doi:10.1007/s40685-017-00520) contains supplementary material, which is available to authorized users. & Stefan Stöckl Stefan.Stoeckl@icn-groupe.fr Jerome Geyer-Klingeberg Jerome.Geyer-Klingeberg@mrm.uni-augsburg.de Markus Hang Markus.Hang@mrm.uni-augsburg.de Andreas W.

Board Independence and Firm Performance in the IT Industry: The Moderating Role of New Entry Threats

The Information Technology (IT) industry is characterized by rapid technological change and fast-moving dynamics, a significant part of which may be attributed to entrepreneurial ventures that pioneer new innovations. Correspondingly, the rate of new entry in the form of entrepreneurial ventures poses a critical risk factor for incumbent IT firms. While theoretical work points out a negative relationship between new entry threats (NET) and firm performance, empirical findings are scarce due to the inability to measure NET properly. Leveraging a novel NET measure based on text-mining approaches, we show that a higher level of NET indeed leads to a drop in the incumbent’s performance. We also show that facing high NET, firms with more independent directors are better able to withstand these threats, possibly due to stronger monitoring and the valuable resources and information provided by the independent directors. Effectively, we circumscribe a set of boundary conditions under which board governance mechanisms may contribute to firm performance. To address the endogeneity issues associated with board independence, we use the enactment of the Sarbanes-Oxley Act and related changes to the NYSE/NASDAQ listing rules as exogenous shocks to create instruments, and our results are robust to the instrumental variable regressions. Further, we show that our findings are generalizable to other high tech industries, and discuss the implications for research and practice.
DIFFERENT PRESERVATIVE SOLUTIONS ENHANCED THE VASE LIFE OF CARNATION CUT FLOWERS (DIANTHUS CARYOPHYLLUS)

The vase life of carnation cut flowers were studied to determine the physiological factors that affect there vase live and longevity. Cut carnation flowers were obtained from commercial grower in Taif, Sudia Arabia, and treated with 100, 200 or 300 ppm of 8hydroxyquniline sulfate (8-HQS) and sucrose at concentrations of 1, 2, or 3%w/v. Longevity of cut carnation was determined on the basis of wilting, chlorophyll retention and carbohydrate degradation. After treatment the cut carnation were kept at room temperature (23+ 1 0 C) at normal day light and natural ventilation. The vase life of cut flowers studied were prolonged by (8-HQS) treatment. The best concentration was 100 ppm. The effect was better when combined with 3% sucrose, which recorded the best vase life compared to other concentration of sucrose. The per cent of wilting was minimized as a result of using this treatments . However the per cent of wilting increased with the increase in concentrations of 8-HQS, and complete wilting occurred after 15, 14 and 14 days when treated with 100, 200 and 300ppm of 8-HQS respectively, while sucrose resulted in the lowest period to reach wilting. Also 8-HQS at 100ppm retarded the chlorophyll as well as carbohydrate degradation during the postharvest life. These experiments were carried out in the laboratory of the Department of Biology -Taif UniversitySudia Arabia. The experiments were repeated three times with three replicates, and a completely randomized design had been used. The difference between means were performed using Duncan multiple range test at 0.05 level. *Corresponding Author Dr. Mohy Eldeen Nour Eldaim Eltaib Elgimabi M.N.

Pattern formation in vortex matter with pinning and frustrated intervortex interactions

We investigate the effects related to vortex core deformations when vortices approach each other. As a result of these vortex core deformations, the vortex-vortex interaction effectively acquires an attractive component leading to a variety of vortex patterns typical for systems with non-monotonic repulsive-attractive interaction, such as stripes, labyrinths, etc. The core deformations are anisotropic and can induce frustration in the vortex-vortex interaction. In turn, this frustration has an impact on the resulting vortex patterns, which are analyzed in the presence of additional random pinning, as a function of the pinning strength. This analysis can be applicable to vortices in multiband superconductors or to vortices in Bose-Einstein condensates.
Superstition and Financial Decision Making Current draft: September 2014

In Chinese culture, certain digits are lucky and others unlucky. We test how such numerological superstition affects financial decision in the China IPO market. We find that the frequency of lucky numerical stock listing codes exceeds what would be expected by chance. Also consistent with superstition effects, newly listed firms with lucky listing codes are initially traded at a premium after controlling for known determinants of valuation multiples, the lucky number premium dissipates within three years of the IPO, and lucky number firms experience inferior post-IPO abnormal returns.
Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1699 Mechanisms of speciation in Silene

Liu, X. 2018. Mechanisms of speciation in Silene. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1699. 42 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0398-7. A fundamental question in the field of evolutionary biology is how new species originate. Investigating speciation benefits from an integrated approach, which requires a solid understanding of ecology, reproductive biology, geographical distribution, underlying genetic architecture of reproductive isolation (RI), demographic history and genomic divergence. In this thesis, I studied the evolution of reproductive isolation in the sister species Silene dioica (L.) Clairv. and S. latifolia Poiret. The aims of the thesis are to investigate (1) the individual and cumulative contributions of extrinsic and intrinsic reproductive barriers between S. dioica and S. latifolia, (2) the genetic architecture of traits associated with reproductive barriers (3) the demographic history of lineage-split between the two species, (4) genomic patterns of divergence between the species. I found that multiple extrinsic preand postzygotic barriers resulting from ecological differentiation contributed most to total RI, while intrinsic barriers had substantial individual strength but contributed weakly to total RI. QTL mapping revealed evidence for genetic coupling of QTLs controlling traits associated with RI, although QTLs were overall widely distributed. QTLs related to sexually dimorphic traits were located on or near the pseudoautosomal region of the sex chromosomes. The best-supported demographic model suggests heterogeneous population size and migration rates among genome-wide loci and points to the presence of barrier loci. Genomic divergence (measured using FST and dXY) was commonly accentuated around the middle of linkage groups and near QTLs for traits associated with reproductive barriers. In summary, the results in my thesis indicate that the speciation process is driven by multiple interacting and complex reproductive barriers. The genomic divergence landscape is shaped by interplay of the magnitude of gene flow, the strength and timing of selection, and other confounding factors such as genomic features.
Vitamin B 6 : a heart-protective molecule through a novel mechanism of increasing histidine-related compounds

It has been reported that a low dietary intake of vitamin B6 is associated with a high risk of mortality from heart disease among Japanese, Americans, and Europeans [1]. Many studies have suggested that vitamin B6 supplementation reduces a risk of heart disease [1–3]. However, the relationship of vitamin B6 intake and risk of heart disease is controversial, and the underlying mechanisms are not fully understood. Since 1969, the role of vitamin B6 in heart disease risk has been mostly addressed through homocysteine hypothesis [4]. However, many recent studies have indicated that the association between vitamin B6 and heart disease risk has been independent of homocysteine, suggesting that vitamin B6 may exert a heart-protective effect through other mechanisms [2,4]. Recently, we found that vitamin B6 supplementation in rats had no effect on homocysteine concentrations in the heart tissue, but markedly increased heart concentrations of histidine-related compounds, such as carnosine, anserine, and histamine [5]. Thus, in the present chapter we propose a novel mechanism underlying heart-protective effect of vitamin B6 and review the currently available knowledge.
Probable Cause, Probability, and Hindsight

When judges assess probable cause, they must do so either in foresight (when determining whether to issue a warrant) or in hindsight (when determining whether to allow the admission of evidence obtained without a search warrant). Although the legal standard for probable cause is the same, and the facts that might support cause are the same, judges who assess probable cause in hindsight invariably know whether a search produced incriminating evidence or not. Research on the hindsight bias suggests that judges will be unable to set aside this knowledge and judge probable cause as if they were working in foresight. In this article, we present three experiments in which we asked 900 state and federal judges to make judgments of probable cause either in foresight or in hindsight, in hypothetical cases. Surprisingly, we found that that judges make similar rulings on probable cause in foresight and in hindsight. We also found that hindsight appears to cloud judges' abilities to assess the likely outcome of the search, but hindsight does not influence their legal judgments.
A review of conversion processes for bioethanol production with a focus on syngas fermentation

Bioethanol production from corn is a well-established technology. However, emphasis on exploring non-food based feedstocks is intensified due to dispute over utilization of food based feedstocks to generate bioethanol. Chemical and biological conversion technologies for non-food based biomass feedstocks to biofuels have been developed. First generation bioethanol was produced from sugar based feedstocks such as corn and sugar cane. Availability of alternative feedstocks such as lignocellulosic and algal biomass and technology advancement led to the development of complex biological conversion processes, such as separate hydrolysis and fermentation (SHF), simultaneous saccharification and fermentation (SSF), simultaneous saccharification and co-fermentation (SSCF), consolidated bioprocessing (CBP), and syngas fermentation. SHF, SSF, SSCF, and CBP are direct fermentation processes in which biomass feedstocks are pretreated, hydrolyzed and then fermented into ethanol. Conversely, ethanol from syngas fermentation is an indirect fermentation that utilizes gaseous substrates (mixture of CO, CO2 and H2) made from industrial flue gases or gasification of biomass, coal or municipal solid waste. This review article provides an overview of the various biological processes for ethanol production from sugar, lignocellulosic, and algal biomass. This paper also provides a detailed insight on process development, bioreactor design, and advances and future directions in syngas fermentation.
Combined Electromagnetic and Drift Diffusion Models for Microwave Semiconductor Device

In this work, we present a numerical model to solve the drift diffusion equations coupled with electromagnetic model, where all simulations codes are implemented using MATLAB code software. As first, we present a one-dimensional (1-D) PIN diode structure simulation achieved by solving the drift diffusion model (DDM). Backward Euler algorithm is used for the discretization of the proposed model. The aim is to accomplish time-domain integration. Also, finite different method (FDM) is considered to achieve space-Domain mesh. We introduced an iterative scheme to solve the obtained matrix systems, which combines the Gummel’s iteration with an efficient direct numerical UMFPACK method. The obtained solutions of the proposed algorithm provide the time and space distribution of the unknown functions like electrostatic potential and carrier’s concentration for the PIN diode. As second case, the finite-difference time-domain (FDTD) technique is adopted to analyze the entire 3-D structure of the stripline circuit including the lumped element PIN diode. The microwave circuit is located in an unbounded medium, requiring absorbing boundaries to avoid nonphysical reflections. Active device results were presented and show a good agreement with other reference. Electromagnetic results are qualitatively in agreement with other results obtained using SILVACO-TCAD.
