Effects of Chemical Treatments ( Iron , Zinc and Salicylic Acid ) and Soil Water Potential on Steviol Glycosides of Stevia ( Stevia rebaudiana Bertoni . )

The most important characteristic of stevia is its high sweetness with zero calories which is due to the presence of Steviol glycosides (SVglys). This research aims to address the effect of salicylic acid (SA) and microelements viz. iron (Fe) and zinc (Zn) under different soil water potentials (-0.5, -3.5, -6.5 and -10 atm) on the production of SVglys and total sugar content in the leaves of stevia. The obtained results indicated that the soil water content and the exogenous application of SA and microelements significantly changed the accumulation of these sweet chemicals in the stevia leaves. The highest values of Stevioside (Stev), Rebaudioside C (Reb C), total SVglys and SVglys yield were obtained in SA + Fe + Zn treatment under the potential of -3.5 atm (76. 82, 2.82, 116.71 mg g DW and 0.836 g plant, respectively). Also, the HPLC results indicated that the highest rates of Rebaudioside A (Reb A) and the Reb A/Stev ratio (sweetness quality) belonged to SA + Zn treatment under the potential of -3.5 atm (28.63mg g DW and 0.433). The application of SA + Fe + Zn was the most effective in terms of Rebaudioside B (Reb B), Dulcoside A (Dulc A) and total sugar (2.31, 5.73 and 335.8 mg g DW, respectively). In general, our results suggest that it can be possible to improve the rate of secondary metabolites (SVglys) and hence the sweetness property in stevia leaves by applying SA, Fe, and Zn and particularly by the integrated application of these three agents.
Sliding , Shuffling and Self Shuffling Singularities of Bounded Invertible Planar Piecewise Isometric Dynamical Systems

It is known that the singularities of bounded invertible piecewise isometric dynamical systems in Euclidean plane can be classified as, removable, sliding and shuffling singularities, based upon their geometrical aspects. It is known that the removable singularities and the shuffling singularities do not generate Devaney-chaos. In other words, the presence of the sliding singularities is necessary for the Devaney-chaos to take place in a certain chaotic set. However, this classification had been left somewhat incomplete in that the distinction between the sliding and the shuffling singularities had not been completely established in simple terms. The purpose of this paper is to clarify this gap, and thus complete the trichotomy. Key–Words: Piecewise Isometric Dynamics, Discontinuous Dynamics, Singularity, Chaos.
Relationships Between Calcalkalic and Alkalic Mineralization Styles at the Copper-Molybdenum Southeast Zone and Copper-Gold Deerhorn Porphyry

Porphyry deposits of Late Triassic to Middle Jurassic age (216 to 183 Ma) occur in the Quesnel and Stikine terranes in British Columbia (McMillan et al., 1995). They are subdivided into calcalkalic and alkalic types on the basis of their hostrock chemistry and styles of alteration and mineralization (Lang et al., 1995; McMillan et al., 1995). Alkalic porphyry deposits such as Mount Milligan, Mount Polley and Lorraine, and calcalkalic porphyry deposits such as Brenda, Highland Valley and Gibraltar, among others, are examples of these two classes. These porphyry deposits commonly occur as clusters of several porphyry centres. The metal ratios, alteration assemblages and hostrock intrusive textures of each porphyry deposit can vary within each cluster (e.g., Casselman et al., 1995; Fraser et al., 1995). Such differences are commonly attributed to emplacement at different crustal depths of the now spatially related porphyry stocks (e.g., Panteleyev et al., 1996; Chamberlain et al., 2007). Recently, porphyry clusters such as Red Chris (Norris, 2011) and Woodjam (Figure 1) displaying both alkalic and calcalkalic features have been recognized. However, the genetic and spatial links between the various deposits in each camp, especially with contrasting assemblages (i.e., calcalkalic and alkalic) are not well understood.
The Knowledge Base of Language Teacher Educationin Kenya NapworaWekesaJesse

The aim of teacher education (TE) is to produce quality teachers who can facilitate the acquisition of knowledge, skills and attitudes by the students. TE embraces a wider perspective of continued learning within the teaching process and the teacher is an essential facilitator in the implementation process of the curriculum. In education therefore, the importance of the teacher takes second place only after that of the learners so that the quality of the teacher is of great concern to the education system. Like any other professional domain, teaching is based on a wide base of specialized knowledge and it is important to note that the generation, dissemination and application of new knowledge is critical in economic growth. The Kenya vision 2030 envisages a knowledge based economy which has the capacity to compete in the global market. An expert understanding of the subject knowledge and effective teaching may be less direct where second language instruction is concerned. Therefore to foster understanding among their students, language teachers and language teacher educators need to know among other things ways of representing the knowledge and skills so that the students are more likely to grasp it. This paper aims at illustrating what language teacher educators need to know about English language and pedagogical issues in order to inspire their students to learn the language, to be effective teachers, improve the quality of teaching and develop professionally. In order to contextualize these ideas, this paper bases its major arguments on language education theories from linguistics, curriculum studies, philosophy, sociology and psychology.
Enhancing BiDAF with BERT Embeddings , and Exploring Real-World Data

In our project, we used BERT embeddings to enhance BiDAF for the task of question answering on real world data. We had 2 main goals: 1) maximize performance (measured by F1 and EM scores) of our combined BERT and BiDAF architecture on the SQuAD 2.0 leaderboard 2) explore our model’s performance on our custom dataset, which contains real customer service interactions from a global cosmetics manufacturer, Benefit Cosmetics. This second goal is an additional exploration that extends the goals of the default project. Our BiDAF models with BERT embeddings achieved dev EM/F1 scores in the 50s after just 2 epochs, instead of the 30 required for the baseline BiDAF. Our best run on the industry dataset was with the BERT fine-tuned model, which achieved dev EM/F1 scores in the 70s on the combined SQuAD + industry dataset. However, this model still did poorly on the industry examples, which highlights the challenges of adapting research to real-world settings. Our best test set performance was with the BERT uncased small model fine tuned for 2 epochs. (EM/F1 72.257/75.586).
Negotiating with Incomplete Information : The Influence of Theory of Mind

The aim of this master’s thesis was to investigate the reasoning behavior of people during negotiations with incomplete information. The question was whether people reason about the knowledge, intentions and beliefs of others in a negotiation setting with incomplete information; do they use so called ‘theory of mind’? Participants played the negotiation game colored trails (for which the use of theory of mind has proven to be useful) against three types of computer agents, who all used a different order of theory of mind (zero, first or second). The negotiations were about the distribution of some resources of which a subset was needed to get to a certain goal location. The goal location of the computer agent was not public knowledge, which invited the participants to reason about the actions and possible goal location of the computer agent. The results showed that people reasoned about the offers of the computer agent. They mainly used first-order theory of mind (reasoning about someone’s mental states) and second-order theory of mind (reasoning about what ideas someone else has about someone’s mental states). The scores of the participants were influenced by the order of theory of mind their opponent used. The participants also used more second-order theory of mind when the opponent used second-order theory of mind. Another outcome was that the participants mainly achieved higher scores when the opponent started the negotiation. Furthermore, it was tested whether a training effect would occur when the participants first played marble drop: a game in which the actions of the opponent (opening a left or right trapdoor) need to be anticipated to get a marble at a preferred location. Unfortunately, no training effect was found, which might be due to the low accuracy of the participants on marble drop or because the game was not similar enough with colored trails. Finally, it was investigated whether personality traits regarding empathy would influence a participant’s results. People who reported that they tended to take into account the perspective of another person in daily life, did not perform better than others.
Acoustic input impedance of infants with normal and pathological middle ear

Newborns and infants often suffer from pathological conditions of the middle ear. In many cases, those conditions comprise liquid in the middle ear, e.g. middle ear effusion, or amniotic fluid during the very first days of life. In order to check the middle ear status in a fast and simple manner, the measurement of the infant’s ear acoustic input impedance could be a useful method. In an ongoing study, the acoustic input impedance of infants’ ears (aged from 2 weeks up to 5 months) was measured in the frequency range from 100 Hz to 10 kHz at ambient pressure. In addition, the middle ear status was assessed by ENT-specialists, yielding an expert classification of “normal” and “pathological” middle ears. The results, on the one hand, show a great variability at low and very high frequencies, reflecting the susceptibility of the measurements to movements and noise of the subjects. On the other hand, there is a frequency range in which a clear discrimination between normal and pathological middle ears seems to be possible. This discrimination appears to profit from the consideration of both the magnitude and phase information of the measured acoustic impedance, indicating that power-based methods may miss important information.
The E ff ect of Recreation in a Snow-Covered Forest Environment on the Psychological Wellbeing of Young Adults : Randomized Controlled Study

Forest recreation can be successfully conducted for the purpose of psychological relaxation, as has been proven in previous scientific studies. During the winter in many countries, when snow cover occurs frequently, forest recreation (walking, relaxation, photography, etc.) is common. Nevertheless, whether forest therapy conducted in a forest environment with a snow cover will also have a positive effect on psychological indicators remains unknown. Furthermore, male subjects frequently participate in forest therapy experiments, whereas females are rarely involved. Thus, in this study, the effectuality of forest recreation during winter and with snow cover was tested on 32 young females. For these reasons, the experiment involved 15 min periods of relaxation in a forest environment or in an urban street environment, in addition to a pre-test under indoor conditions (randomized controlled study). Four psychological questionnaires Profile of Mood States (POMS), Positive and Negative Affect Schedule (PANAS), Restorative Outcome Scale (ROS), Subjective Vitality Scale (SVS)) were administered to participants before and after interventions. Results showed that participants’ levels of negative mood, as measured by different aspects of the POMS questionnaire (tension/anxiety, anger/hostility, depression/dejection, confusion, and fatigue), decreased after exposure to the forest environment. In contrast, both tension/anxiety and anger/hostility increased in the urban street environment. The indicator of negative affect from the PANAS questionnaire also increased after exposure to the urban street environment, whereas the indicator of positive affect based on PANAS was higher in the forest environment than in the urban street environment. Restorativeness and subjective vitality exhibited higher values after exposure to the forest environment in comparison to those from the control and pre-test. The changes in these indicators demonstrate that forest recreation in the snow during winter can significantly increase psychological relaxation in females, as well as show that recreation can be successfully conducted under these winter conditions.

Field test of resonant frequency monitoring utilizing background vibration in various buildings

A number of big intermittent aftershocks often follows a great earthquake. Even if a certain building escapes from the collapse due to the first main quake, there is no guarantee that the building can survive from the aftershocks. If it is possible to monitor the condition of the buildings constantly using some faint random vibration caused by background vibration such as wind, weak earthquakes and traffic vibration, the safety will be more secured. The authors have proposed cumulative harmonic analysis that emphasizes the hidden resonances in a time-invariant transfer function, and conducted the experimental monitoring of the resonant frequency in an actual building from the analysis of the faint random vibration on the building caused by the background vibration. From the results of comparison with the measured values of the resonant frequency by an active diagnosis it is confirmed that the estimation of the resonant frequency by the proposed method obtains an accurate value only including few percent error. This report describes about the results of field tests on various buildings using the proposed method.
System Analysis of Multilane Traffic Flow Models with Different Lane Changing Motivations

The present research was aimed at mathematical modeling of essentially unsteady-state traffic flows on multilane roads, wherein massive changing of lanes produces an effect on handling capacity of the road segment. The model takes into account drivers’ motivations for lane changing before the crossing caused by the necessity of the maneuver on entering multilane road crossing. The model is based on continua approach. However, it has no analogue in the classical hydrodynamics because momentum equations in the direction of a flow and in orthogonal directions of lanechanging are different. To provide stability and accuracy of the numerical solution we use the computation method common to gas dynamics. Numerical simulations of traffic flows in multilane roads were performed and their results are presented.
The Origin of Japanese Omotenashi in Man

In this paper, the authors build a hypothesis that Japanese omotenashi has roots in the banquet, utage, described in Man-yo-shu, the oldest anthology of verse. The purpose of this paper is to analyze the utage in Man-yo-shu, to clarify the roles of it and the benefits for the participants in the viewpoint of value of experience. The authors discuss the characteristics of utage in Man-yo-shu, with reference to Turner’s theory of communitas, liminality and liminoid. The comparison between utage in Man-yo-shu and brand community leads to the positioning of utage both on individual level and collective level in context of culture. Toshimi Aishima and Yoshinobu Sato Specifically, the roles of utage in community and the benefits given by utage to the participants are to be analyzed in the point view of service dominant logic (Vargo and Lusch, 2004 ; Vargo and Lusch, 2008), service logic ( 2008 ; and Gummerus, 2014), customer dominant logic (Heinonen et. al. 2010 ; Heinonen et. al., 2013 ; Rihova et al., 2013 ;), or experience marketing research (Conway and Leghton, 2012 ; Helkkula et. al., 2011 ; Holbrook, 2005 ; Holbrook, 2006 ; Holbrook and Hirshman, 1982 ; Holt, 1995 ; Tynan and McKechnie, 2010 ; Verleye, 2015). For the concrete problems, the authors compare between the features of customer value of co-creation that is shown in the study of the Latin School of Societing (Cova, 1077 ; Cova and Cova, 2002), application of Turner’s theory of communitas (M Ellis, 2011 ; Kim and Jamal, 2007 ; Rihova, 2013), and the study of brand community (McAlexander et. al., 2992 ; Muniz and O’Guinn, 2001 ; Schau et al., 2009) and the features of utage in Man-yo-shu as community and those of value co-creation. This paper is to analyze the costomer value of co-creation in high context culture, which has not been discussed in previous research. The Characteristics of the in 1 Overview of In the beginning, the authors show the features of Man-yo-shu in historical context. Man-yoshu, Japan’s oldest anthology of verse in existence, consists of twenty volumes. It contains forty five hundred poems in total, most of which are fixed form of short poems as waka, made by a broad range of people from emperors to commons, from eastern areas to Kyushu area. There are many mysteries about establishment of Man-yo-shu : who edited the great collection, when, why or how has not been clearly unraveled. Roughly it is said to have been completed in the end of Nara period through several editing stages. The anthology has three main categories : general poems, love poems, and elegies. General poems indicate those made in public or formal settings such as banquets and ceremonies. Most of love poems were meant to entertain the others at some parties, rather than describe a person’s sincere feelings to the one’s beloved. Again, elegies were to express not one’s private feelings but their common sorrow (Kajikawa, 2000, pp. 176 86 ; Furuawa, 2004, pp. 17 28, 31 33 ; Iwashita, 2014, pp. 2 14). Usually the poems of Man-yo-shu are divided into four periods. The first period, from 630 104
Is Galectin 3 more Accurate than Brain Natriuretic Peptide in Diagnosing Chronic Heart Failure? A Systematic Review

Heart failure (HF) is a clinical syndrome in which the pumping action of the heart is impaired. Globally, more than 23 million people are affected by HF1,2. Also, about 160,000 people across the United Kingdom and 5.8 million people suffer from HF in the United States of America and contribute to 50,000 deaths annually in the United States of America. The main cause of HF has been attributed to left ventricular failure3,4. It has been estimated that about 58% of the population affected by HF following myocardial infarction is often asymptomatic5. Therefore, often misdiagnosed or underdiagnosed in primary care6. Hence, asymptomatic AMI can lead to symptomatic HF that may masquerade as COPD. This is important as a good biomarker will help identify the problem more accurately before individual suffering from HF deteriorates.
SYLLABLE POSITIONS AS DISTINCT ARTICULATORY PATTERNS : EVIDENCE FROM RUSSIAN *

It has been observed that syllable-initial and syllable-final consonants tend to exhibit different patterns of articulatory organization. These differences, or syllable position effects, are often manifested in the relative timing of articulatory gestures and their reduction in magnitude, or the degree of constriction (see Krakow 1999 for a review). Syllable-initial consonants, for instance, tend to show more stable patterns of coordination and “tighter” articulatory constrictions than the same consonants in syllable-final position. A classic example of these contextual differences involves positional allophones of the American English /l/, namely the syllable-initial “clear” [l] as in ‘leap’ and the syllable-final “dark” [ł] as in ‘peal’. Investigations of these allophones using a variety of methods (Giles & Moll 1975, Sproat & Fujimura 1993, Browman & Goldstein 1995, Gick in press) have shown that both involve two articulatory gestures, a tongue tip closure at the alveolar ridge and a tongue body retraction (velarization). The difference between the dark and clear /l/ is in the timing and magnitude of these gestures. First, while the tongue tip gesture is synchronous with the tongue body gesture syllable-initially, the latter follows the former syllable-finally. Second, the relatively consistent achievement of the tongue tip target syllable-initially contrasts with the frequent lack of complete closure syllable-finally, particularly in casual and fast speech. Articulatory differences in timing and magnitude between syllable-initial and syllable-final allophones are not limited to the lateral. They have been documented for other English consonants: oral and nasal stops (Browman & Goldstein 1995, Keating 1995, Byrd 1996, Turk 1994, Fougeron & Keating 1997), the glides /w/ and /j/, and rhotic /r/ (Gick 1999). The findings suggest that positional variants of English consonants in general reflect distinct patterns of syllable organization at the articulatory level.
Developing an Accessible 3 D Printing Pipeline

Digital technology provides an opportunity for people with disabilities to be involved in artistic activities, such as virtual sculpting whose output can be fabricated using 3D printing. Existing accessible solutions, however, present mainly a set of separate tools rather than a whole cohesive production pipeline which takes into an account the specific needs of the user group. Challenges include accessible user interfaces for all pipeline steps, suitable shape modelling operations, ”3D Print” button and model data formats that require no post-processing or clean-up operations for the Direct Fabrication step. In this paper we discuss an accessible pipeline which includes 3D modelling and 3D printing, providing an example of a 3D modelling system with developed special-purpose applications allowing children with complex disabilities to participate in sculpting activities through accessible interfaces such as eye-gaze control.
An Investigation into Barriers to the Adoption of E-Procurement within Selected SMEs in Saudi Arabia

This paper investigates the potential barriers to e-procurement adoption in Saudi Arabian SMEs. The study builds its theoretical foundation on Gunasekaran and Ngai’s (2009) model of e-procurement adoption in SMEs on the south-east coast of the USA, which it applies to the Saudi Arabian SMEs to determine their barriers to the adoption of e-procurement. Data was collected from a number of staff from four selected Saudi Arabian SMEs using both qualitative and quantitative tools. This study looks at a number of barriers and analyses their relative importance using hierarchical analytic process.
BERTQA - Attention on Steroids

In this work, we extend the Bidirectional Encoder Representations from Transformers (BERT) with an emphasis on directed coattention to obtain an improved F1 performance on the SQUAD2.0 dataset. The Transformer architecture on which BERT is based places hierarchical global attention on the concatenation of the context and query. Our additions to the BERT architecture augment this attention with a more focused context to query (C2Q) and query to context (Q2C) attention via a set of modified Transformer encoder units. In addition, we explore adding convolution-based feature extraction within the coattention architecture to add localized information to self-attention. We found that coattention significantly improves the no answer F1 by 4 points in the base and 1 point in the large architecture. After adding skip connections the no answer F1 improved further without causing an additional loss in has answer F1. The addition of localized feature extraction added to attention produced an overall dev F1 of 77.03 in the base architecture. We applied our findings to the large BERT model which contains twice as many layers and further used our own augmented version of the SQUAD 2.0 dataset created by back translation, which we have named SQUAD 2.Q. Finally, we performed hyperparameter tuning and ensembled our best models for a final F1/EM of 82.317/79.442 (Attention on Steroids, PCE Test Leaderboard).
