Quercirhiza quadratum: a revision of the characters and identity of the ad type ectomycorrhiza

The well-known AD type, described first by Giraud in 1988, is considered as a competitor in black truffle (Tuber melanosporum Vittad.) plantations. It has been mainly observed in T. melanosporum and T. magnatum Pico plantations in France and Italy. This ectomycorrhiza has always been observed on roots of oak (Quercus ilex L. and Q. faginea Lam.) and hazelnut (Corylus avellana L.) plantations with “burnt” areas around the trees, even in those that do not produce black truffle sporocarps, so it can create false expectations in young plantations. The AD type has also been described in nurseries, as a competitive ectomycorrhiza on seedlings inoculated with black truffle. In Spain, AD type has been detected in black truffle plantations and natural holm oak stands in Navarra, Soria, Huesca, Zaragoza, Teruel, Castellon and Valencia. In 2005, De Roman & De Miguel, suggested that AD type could be a telephoroid type due to its anatomical and morphological characters. In 2006, Baciarelli-Falini et al. using molecular techniques identified this type as an Ascomycotina belonging to Pezizales. The detailed anatomical, morphological and molecular study of the AD type led to a description as Quercirhiza quadratum (Agueda et al. 2008). Based on the anatomical and morphological characters, the AD type belongs to the Ascomycotina. The presence of Woronin bodies on hyphal septa, and the sometimes slightly dissolved septa, are two typical characters of this group. The DNA sequences obtained from the AD types studied showed close similarities with members of Pyronemataceae and Sarcosomataceae (Pezizales). Both taxonomic groups correspond to the same AD type as found by Baciarelli Falini et al., (2006). One of the studied sequences showed a close identity (100% maximum identity, 84% coverage) with Trichophaea woolhopeia (Cooke & W. Phillips) Arnould, although records of this fungal species are scarce in the Iberian Peninsula.

Vice-Chancellors Influence on Academic Staff Intentions to Use Learning Management Systems

Universities world over are increasingly deploying learning management systems to enhance the quality of teaching and learning as well as to increase access to higher education. However, since technology rejection is common, the future of universities depends on their instructor's capacity to adopt and diffuse such technologies to meet the intricate needs of the academic masses. Consequently, the purpose of this paper is to investigate the factors that inhibit or accelerate the adoption and diffusion of Learning Management System (LMS) by academic staff for teaching and learning activities. The paper is based on a questionnaire survey completed by 82 lecturers from a selected sample of public and private universities in Kenya. The results of analysis indicate that Vice Chancellors/Chief Executive Officer (CEO) characteristics, namely:- keenness on modern information communication and technologies (ICTs), Influence on ICTs development, and, visionary ICT leadership are important determinants of LMS adoption and diffusion by instructors in higher education. Further, organizational variables of Subjective norm (SN), availability of ICTs (AICT), Organizational support (OS), Organizational readiness (OR), and top management support (TMS) were related to behavioural intentions to use (BIU) LMS by academic staff for teaching and learning. In addition, in this paper, the technology acceptance model (TAM) was also extended to include VCs/CEO characteristics, and organizational readiness. Results from the research also determined the factor that was dominant in predicting the acceptance of LMS which was top management support. This paper further validated the use of TAM, as a supportive framework for investigating the academic staff intentions to use Learning Management Systems for teaching and learning.

Media framing of the Sri Lankan Civil War

THESIS: Media Framing of the Sri Lankan Civil War STUDENT: Krishan Jayashanka Siriwardhana DEGREE: Master of Arts COLLEGE: College of Communication, Information, and Media DATE: May 2017 PAGES: 81 The Liberation Tamil Tigers of Eelam (LTTE) fought with the Sri Lankan government for more than three decades for a separate state for Tamil speaking people in Sri Lanka. The war had significant social, political and economic impacts on Sri Lanka. This study analyzed the types of media framing strategies used by The Island and the Daily Mirror newspapers in reporting the war. The study employed Gamson and Modigliani’s (1989) media framing devices as the theoretical framework. The findings revealed that the newspapers’ framing of the war supported and promoted the dominant Sinhala Buddhist standpoint on the war.
On the stability of continuously stratified quasi-geostrophic hetons

In this paper we examine the stability of quasi-geostrophic hetons in a stably, continuously stratified fluid. To this purpose we first determinate numerically equilibrium states. Equilibrium hetons consist of two vortices of equal and opposite strength lying at different depths that are steadily translating without deforming. The situation is studied through a parameter space comprising of the vertical offset between the vortices, their horizontal separation distance and their aspect ratio. The study first shows that the equilibrium vortices are not only strongly deformed in the vertical but that their instability modes are also varying within the height of the structures. The main purpose of the present contribution is to study families of equilibria which stem from the case of two vertically aligned cylindrical vortices. It is however shown that other branches of solutions exist with different properties. The paper concludes that hetons may be sensitive to baroclinic instabilities provided the separation distance between the poles of the hetons is moderate both in the horizontal and in the vertical directions. The hetons become stable and efficient ways to transport properties as far as the poles are distant from one another. The critical separation distance in a non-trivial function of the radius-to-height aspect ratio of the poles.
Uptake of dissolved inorganic nitrogen, urea and amino acids in the Scheldt estuary: comparison of organic carbon and nitrogen uptake

Uptake of dissolved ammonium, nitrate, nitrite, urea and amino acids was studied in the Scheldt estuary in different seasons over a salinity gradient. The importance of inorganic nitrogen sources was compared to that of urea and amino acids and the relative use of urea and amino acid nitrogen and carbon was studied. Urea and amino acids constituted up to 43 and 29% of total nitro- gen uptake, respectively, and were of similar importance as inorganic substrates. Ammonium oxida- tion by nitrifiers and ammonium uptake by algae and bacteria were of similar magnitude. In January, April and November, amino acids constituted a source of both nitrogen and carbon while urea mainly constituted a source of carbon. During the summer months, amino acids were used mainly as a source for nitrogen, while urea was a source for both carbon and nitrogen; urea was rarely used as nitrogen substrate alone. Due to this seasonal uncoupling of nitrogen and carbon assimilation, dually labeled substrates are necessary to assess the importance of urea and amino acids as substrates for organic nitrogen and carbon.
Does Mindfulness Cultivate Social Connectedness? A Narrative Review on a Novel Modality of Social Emotional Learning

The previous decade has witnessed an explosion of mindfulness research in Western psychology. Although most research has been conducted in behavioral medicine and cognitive behavior therapy, only recently have researchers begun investigation into associations between mindfulness and social connectedness. This paper conducted a literature review of fourteen empirical studies on this subject, all with nonclinical population. Findings are: (a) correlational studies demonstrated consistent, moderate positive correlations between mindfulness and connectedness (e.g., relatedness, empathy, compassion); (b) there was also a moderate positive correlation between mindfulness and satisfaction in romantic relationship; (c) interventions modeled after Mindfulness-Based Stress Reduction (MBSR; Kabat-Zinn, 1990) demonstrated positive effects on connectedness (e.g., empathy, spirituality, forgiveness); (d) a mindfulness-based intervention for relationship enhancement (MBRE) confirmed its efficacy in relationship functioning and individual well-being; and (e) no intervention research demonstrated the mediating effect of mindfulness on social outcomes. Future directions are discussed in terms of measurement and research design.
Elliptical and Circular Step-Index Fibers with Conducting Helical Windings on the Core-Cladding Boundaries for Different Winding Pitch Angles - a Comparative Modal Dispersion Analysis

The propagation characteristics of an elliptical step-index fiber with a conducting helical winding on the core-cladding boundary are investigated analytically and compared with those of a circular step index fiber with a conducting radial winding. Our optical waveguides are unconventional: in view of the existence of helical conducting windings on the core-cladding boundaries. Appropriate coordinate systems, circular cylindrical and elliptic cylindrical, are chosen for the circular and elliptical fibers. Applying the boundary conditions as modified by the presence of conducting helical windings, the characteristic equations are obtained for both the fibers. Dispersion curves are also obtained for two special values of the helical pitch angle ψ, namely, for ψ = 0◦ and ψ = π2 for each fiber and the results have been compared. It is found that the introduction of the helical winding has two main effects on the characteristics of both types of fibers. These are: (1) The helix introduces band gaps and (2) has the effect of splitting a mode into a pair of adjacent modes In the case of the elliptical helically clad waveguide we find two band gaps for V < 30 whereas for circular guide we have only one band gap in the same range of V -values, V being the normalized frequency parameter. 2 Kumar and Singh II
Bionanomaterials: Synthesis, Physico-Chemical and Multivariate Analyses of the Dicotyledonatae and Pinatae Essential Oil/ β β β β β - cyclodextrin Nanoparticles

The paper presents a multivariate analysis (PCA-principal component analysis) of the essential oils from Dicotyledonatae and Pinatae classes encapsulated in β-cyclodextrin. The essential oil/β--cyclodextrin complexes were obtained by solution method. Uncomplexed volatile oils and complexes with β--cyclodextrin were analyzed by gas chromatography-mass spectrometry (GC-MS) and thermogravimetry (TG), respectively. In order to evaluate the composition of the encapsulated oil, this was extracted from the complex and analyzed by GC-MS. For the GC data of the uncomplexed essential oils and the complexed ones, a powerful multivariate statistical procedure (PCA) was applied. Samples were very good classified in botanical classes or in uncomplexed and complexed ones using the GC data of the monoterpene compounds.
Economic viability of photovoltaic water pumping systems in the desert of Tunisia

This work allows evaluating the economic interest of photovoltaic water pumping systems in the desert of Tunisia which will have to satisfy an average daily volume of 40 m 3 throughout the year compared to another very widespread energy system in the area, the diesel genset (DG), by using the method of the life cycle cost (LCC). The cost per m3 of water was calculated for this system. It is found that the life cycle cost for PV system is 0.500 TND /m3 and the life cycle cost diesel genset is 0.900 TND /m3. The present study indicates economic viability of photovoltaic water pumping systems in the desert of Tunisia.

Lidar observation of the 2011 Puyehue-Cordón Caulle volcanic aerosols at Lauder, New Zealand

Abstract. On 4 June 2011, the Puyehue-Cordon Caulle volcanic complex (40.6° S, 72.1° W) in Chile erupted violently and injected volcanic aerosols into the atmosphere. For the safety of civil aviation, continuous lidar observations were made at Lauder, New Zealand (45.0° S, 169.7° E), from 11 June through 6 July 2011. The purpose of our study is to quantify the influence of the volcanic ejections from large eruptions, and we use the data from the ground-based lidar observation. We analyzed lidar data at a wavelength of 532 nm and derived the backscattering ratio and depolarization ratio profiles. During June and July, within the altitude range of 10–15 km, the volcanic aerosols had high depolarization ratios (20–35%), an indication of non-spherical volcanic ash particles. The time series of the backscattering ratio during continuous observations had three peaks occurring at about 12-day intervals: 26.7 at 11.2 km on 11 June, 18.1 at 12.0 km on 23 June, and 5.3 at 11.1 km on 6 July. The optical depth of the volcanic aerosols was 0.45 on 11 June, when the continuous lidar observation started, 0.31 on 23 June, and 0.12 on 6 July. The depolarization ratio values remained high up to a month after the eruption, and the small wavelength exponent calculated from the backscattering coefficients at 532 nm and 1064 nm suggests that a major constituent of the volcanic aerosols was large, non-spherical particles. The presence of volcanic ash in the stratosphere might affect the error in Greenhouse gases Observing SATellite (GOSAT) XCO2 retrieval using the 1.6 μm band. We briefly discuss the influence of the increased aerosols on GOSAT products.
Evaluation of the Biomechanical Performance of Youth Football Helmets

Youth football helmets currently undergo the same impact testing and criteria as varsity helmets, although youth football players differ from their adult counterparts in anthropometry, physiology, and impact exposure. This study aimed to relate football helmet standards testing to on-field head impact magnitudes for youth and varsity football helmets. Head impact data, filtered to include only impacts to locations in the current National Operating Committee on Standards for Athletic Equipment (NOCSAE) standard, were collected for 48 collegiate players (ages 18 to 23) and 25 youth players (ages 9 to 11) using helmet-mounted accelerometer arrays. These on-field data were compared to a series of NOCSAE standard drop tests with a youth and varsity Riddell Speed helmet. In the on-field data, the adult players had a higher frequency of impact than the youth players, and a significant difference in head acceleration magnitude only existed at the top location (p < 0.001). In the laboratory drop tests, the only significant difference between the youth and varsity helmet was at the 3.46 m/s (61 cm) impact to the front location (p = 0.0421). Drop tests generated head accelerations within the top 10% of measured on-field impacts, at all locations and drop heights for both helmets, demonstrating that drop tests are representative of the most severe head impacts experienced by youth and adult football players on the field. Current standards have been very effective at eliminating skull fracture and severe brain injury in both populations. This analysis suggests that there is not currently a benefit for a youth-specific drop test standard for catastrophic brain injury. However, there may be such a need if helmet testing standards are updated to address concussion risk reduction, paired with a better understanding of differences in concussion tolerance between youth and adult populations.
Reinterpreting The Meaning Of Breakdown

Alternating bargaining has been extensively used to model two-sidednegotiations. The celebrated model of Rubinstein (1982) has provided a formaljustification for equitable payoff division. A typical assumption of these models underrisk is that the breakdown event means a complete and irrevocable halt in negotiations.We reinterpret the meaning of breakdown as the imposition to finish negotiationsimmediately. Specifically, after breakdown the last offer becomes definitive. WhileRubinstein? s model predicts an immediate agreement with stationary strategies, weshow that the same payoff allocation is attainable under non-stationary strategies.Moreover, the payoffs in delayed equilibria are potentially better for the proposer thanthose in which agreement is immediately reached.
Research of Collaborative Filtering Recommendation Algorithm for Short Text

Short text, based on the platform of web2.0, gained rapid development in a relatively short time. Recommendation systems analyzing user’s interest by short texts becomes more and more important. Collaborative filtering is one of the most promising recommendation technologies. However, the existing collaborative filtering methods don’t consider the drifting of user’s interest. This often leads to a big difference between the result of recommendation and user’s real demands. In this paper, according to the traditional collaborative filtering algorithm, a new personalized recommendation algorithm is proposed. It traced user’s interest by using Ebbinghaus Forgetting Curve. Some experiments have been done. The results demonstrated that the new algorithm could indeed make a contribution to getting rid of user’s overdue interests and discovering their real-time interests for more accurate recommendation.
BAYESIAN MODEL SELECTION FOR ELECTROMAGNETIC KAON PRODUCTION ON THE NUCLEON

We present the results of a Bayesian analysis of a Regge model for K+Λ photoproduction. The model is based on the exchange of K+(494) and K*+(892) trajectories in the t-channel. For different prior widths, we find decisive Bayesian evidence (Δ ln Ƶ ≈ 24) for a K+Λ photoproduction Regge model with a positive vector coupling and a negative tensor coupling constant for the K*+(892) trajectory, and a rotating phase factor for both trajectories. Using the χ2 minimization method, one could not draw this conclusion from the same dataset.
Reliability performance of wireless sensor networks for civil infrastructure – Part II: prediction and verification

AbstractApplication studies on wireless sensor networks (WSN) are actively conducted in the construction industry. However, there are several technical limitations including signal interference caused by the characteristics of wireless sensors, reliability degradation in wireless communication and uncertainty of configuring a network topology. This may lead to a decline in reliability and performance of real-time data acquisition methods. Thus, the paper developed a model capable of predicting reliability performance of wireless signals applied to civil infrastructures. The measured and predicted values of wireless signals are compared and analyzed through a field experiment carried out in an actual bridge to verify the prediction model suggested herein. As a result of the analysis, the prediction model demonstrated a variation up to 8.4% compared with actual measurements, proving the high accuracy of the prediction model. Furthermore, the reception rate at short distances within a 5 m radius is at least .
Correlation Neglect, Naïve Diversification, and Irrelevant Information as Stumbling Blocks for Optimal Diversification

The paper analyses on an experimental basis the phenomenon of non-optimal diversification in portfolio choice decisions. The main obstacles to achieving optimal diversification are investigated â€“ the correlation neglect hypothesis and information processing, both of which lead to suboptimal diversification decisions. This is possible by constructing the investment alternatives in the experimental design in such a way that the Markowitz efficient frontier is reduced to a single point in the return-risk diagram, enabling unambiguous interpretation of the results. The experiment shows that the subjects are not in a position to use the information that is most relevant to investment alternatives and ignore correlation in making their portfolio choice. Moreover, they are unable to prescind from clearly irrelevant information. The first effect dominates the second â€“ in the absence of irrelevant information, the subjects neglect the correlation between the assets. The effect is even more pronounced with additional irrelevant information. These findings shed more light on individual investment behaviour and pose questions about regulating pension funds to ensure optimal diversification of pension savings.
