Mobile Interactive Translation Teaching Model Based on “Internet +”

Nowadays, we have entered a new era of globalization and information. The new information technology featured by Internet and computer has permeated every sphere of our lives and affected our viewpoint of consuming and life-style. As for translation teaching, the traditional translation-teaching model cannot satisfy the needs of modern education. In China, the translation teaching based on Internet has become the norm. And more and more people have accepted the mobile learning model. Under such background, this study analyzes the features of mobile teaching and constructs a new model of mobile interactive translation teaching from the perspective of constructivism. The paper also preliminarily testified the new model by taking three different social interactive tools that are most popular in China as example, that is, WeChat, QQ, and Micro-blog. The result shows that this new model based on “Internet +” can improve translation teaching and learning.

The olives and probiotic foods of the invention are an effective means to treat or prevent intestinal disorders or restore the intestinal flora after antibiotic therapy. The aim of this studywas to investigate adhesion and viability of probiotic bacteria (Lactobacillus acidophilus and Lactobacillus casei separately and a blend of them) on olive and physicochemical and sensory charactristics of probiotic fermented olive during 90 days storage in 4 ⁰C . Results indicated thatthe number of live probiotic bacteria on the surface of the sample olive containing Lactobacillus acidophilus for 45 days and all the samples in brine for 60 days was higher than the standard amount (106cfu/ml). Gradually, it was decreased significantly (p<0.05) and at the end of storage period, the olive sample containing Lactobacillus acidophilus had the highest survival. Acidity and pH of the samples were significantly (p<0.05) increased and decreased respectively.
Versatile copolymers from [L]-lactide and [D]-xylofuranose

The new monomer 1,2-o-isopropylidene-[d]-xylofuranose-3,5-cyclic carbonate (IPXTC) was prepared. The organometallic catalysts AlR3−H2O (R = ethyl, isobutyl), ZnEt2−H2O, and Sn(Oct)2 were evaluated for the copolymerization of [l]-lactide ([l]-LA) with IPXTC. This work showed that Sn(Oct)2 was preferred for the formation of high molecular weight copolymers. For example, a copolymerization ([l]-LA/IPXTC = 83:17 mol/mol) at 120 °C for 6 h gave poly([l]-LA-co-7 mol % IPXTC) with an Mn and polydispersity (Mw/Mn) of 78 400 and 1.9, respectively. The comonomer reactivity ratios were 4.15 and 0.255, respectively, for [l]-LA and IPXTC copolymerizations conducted at 120 °C, M/C = 200, and Sn(Oct)2 as catalyst. Structural investigations by NMR revealed that [l]-LA/IPXTC copolymers had short average IPXTC repeat unit segment lengths. Increased copolymer IPXTC content resulted in products with lower melting transition temperatures but higher glass transition temperatures. To obtain hydroxyl functionalized P([l]-LA) cop.
Effect of Land Use on Abundance and Diversity of Nematode Destroying Fungi and Soil Nematodes in Embu County, Kenya

Belowground biodiversity is one of the key indicators of the sustainability of a land use. This study sought to document the occurrence and diversity of nematode destroying fungi in an area characterized by small scale agriculture in Embu County, Kenya. The study area was divided into six main land use types namely; coffee, fallow, forest, maize/bean intercrop, napier and tea. Nematode destroying fungi were extracted from five soil samples from each of the land uses. A total of 161 isolates of nematode destroying fungi belonging to nine genera and 19 species were isolated and identified. The genera represented were Arthrobotrys, Dactyllela, Dactylaria, Harposporium, Monacrosporium, Myzocytium, Nematoctonous, Paecilomyces and Stylophage . The occurrence of nematode destroying fungi was significantly (P=0.02519) affected by the land use types in the study area. With the exception of Arthrobotrys superb, Dactyllela haptospora, Dactyllela reticulate, Harposporium anguillulae and Monacrosporium ellipsoporum all the other 19 isolated species were not affected by land use types. The highest total mean occurrence of nematode destroying fungi was recorded in maize/bean, followed by nappier, coffee, forest, fallow and tea , in that order. The respective frequency of detection of the fungal species was 7.6, 7.2, 5.0, 4.0 and 3.6. The Shannon index of diversity was highest and lowest at 1.971and 1.177 in the land under maize/bean intercrop and tea, respectively. The species richness was higher in napier, followed by maize bean, coffee, forest and least in tea. Out of the fungi that were isolated, the highest proportion of 23% was from the maize/bean intercrop, while the least 11% was from land under ea. Arthrobotrys oligospora was the most frequently isolated species with a frequency of 24% while Nematoctonus pachysporus had the least frequency of occurrence of 1%. It can be concluded that land use influences the diversity of nematode destroying fungi and nematodes in the soil. More work is needed to determine the efficacy of these indigenous isolates on plant parasitic nematodes.
Application of chronic care model for self- management of type 2 diabetes: focus on the middle-aged population of Pakistan

This article discusses the potential application of Chronic Care Model (CCM) for self-management of type 2 diabetes focusing on the middle-aged population of rural area of Pakistan. The article further highlights the variations of chronic care model and the evidence for its efficacy and elaborating the elements of the model that are used in primary health care. The features of Chronic Care Model (CCM) have been highlighted including the socio-ecological approach to diabetes self-management and community-based partnership for improving chronic disease management. The two components of the chronic care model such as patient selfmanagement support (SMS) and delivery system design (DSD) have been proposed for type 2 diabetes patients in the middle-aged population of rural area of Pakistan to see the effectiveness of their intervention in improving the patient quality of life, risk behaviour and knowledge and adherence to treatment. The chronic care model offers an ideal framework to support diabetes self-management education and support because it provides a sound basis on which to promote self-management.
An Algorithm for Spread Arbitrage Process in the CSI-300 Futures Market

With the development of modern capital markets, the stock index futures have become one of the most active investment instruments in the world. The arbitrage of stock index futures actually plays a very important role in making the price of stock index futures be rational and activating the market. In the present paper, we propose an algorithm of spread arbitrage process, which aims to improve the statistical arbitrage strategy of pairs trading based on co-integration. Firstly, the long-term relationships among index futures are detected by co-integration tests. Then the algorithm is applied to the IF1207 and IF1208 contracts of CSI300 futures in China to test its performance. The empirical results suggest that the average profit from spread arbitrage is statistically significant and the rates of return of spread arbitrage are very attractive.

Anti-Nosemosis Activity of Aster scaber and Artemisia dubia Aqueous Extracts

Abstract In our previous study, we demonstrated that the ethanol extracts of Artemisia dubia (A. dubia) and Aster scaber (A. scaber) have anti-nosemosis activity. In our present study, we intend to establish the anti-nosemosis activity of aqueous, ethyl acetate (EA), and butanol (BuOH) extracts of A. dubia and A. scaber. In order to determine the optimal dose, we performed both in vitro and in vivo toxicity for all the extracts and also carried out anti-nosemosis experiments. Although all of the extracts (aqueous, EA, and BuOH) showed in vitro and in vivo anti-nosemosis activity in a dose-dependent manner, the aqueous extracts of A. dubia and A. scaber showed more potent anti-nosemosis activity than the EA and BuOH extracts. Moreover, an aqueous extract of A. dubia + A. scaber demonstrated stronger anti-nosemosis activity compared with the aqueous extracts of either A. dubia or A. scaber alone. Although the main ingredients in A. dubia and A. scaber remain unclear, our results suggest that the active components of A. dubia and A. scaber could dissolve in the aqueous fraction.
EFFECT oF ARONIA MELANOCARPA FRUIT JUICE oN ALCoHoL-INDUCED DEPRESSIVE-LIKE BEHAVIoR IN RATS

PURPOSE : The present study investigated the effects of Aronia melanocarpa fruit juice (AMFJ) on behavior and biochemical indices of liver toxicity and oxidative stress in female Wistar rats subchronically treated with ethanol. MATERIAL AND METHODS : Ethanol was applied for 14 days at a daily dose of 8 g/kg divided in two equaloral gavages. AMFJ was applied as a pretreatment 1 hour before each ethanol administration at doses of 2,5 ml/kg, 5 ml/kg and 10 ml/kg. Effects on behavior were investigated using the open field test (OFT) for locomotor activity, elevated plus maze test (EPM) for anxiety and forced swim test (FST) for depression. The biochemical markers were: liver enzymes for liver toxicity and thiobarbituric acid reactive substances (TBARS) for oxidative stress. RESULTS : Ethanol induced a significant reduction in locomotor activity in the OFT and EPM. The FST showed that ethanol induced a depressive-like behavior. These effects were not accompanied by liver toxicity. AMFJ did not significantly affect the reduced by ethanol central nervous excitability demonstrated in the OFT and EPM. It showed an anti-depressive effect as evidenced by the reduction of immobility time in the FST. This effect is not likely to be due to the pronounced antioxidant activity of AMFJ as ethanol did not induce oxidative stress estimated by the TBARS. CONCLUSION : In this model of ethanol-induced changes in rat behavior, AMFJ showed an anti-depressant like effect which might be due to the polyphenolic ingredients of the juice.
Qualitative Interpretation of Gravity and Aeromagnetic Data in West of Tikrit City and Surroundings, Iraq

The qualitative interpretation of anomalies of the gravity and the magnetic fields at the west of Tikrit City and surroundings, Iraq, was carried out. According to the tectonic framework of Iraq, the study area is classified as a part of the stable shelf unit. The polynomial technique was employed to separate the residual-regional anomalies as a first step in the qualitative interpretation. Bouguer gravity anomaly map did not exhibit any clear closures. The magnetic maps showed remarkable high closure in the central eastern part of the study area. The regional gravity and magnetic fields values decline towards the eastern parts of the maps (Mesopotamian Basin) in consistent with the increase in the sedimentary cover (basement depth). The residual gravity and magnetic maps displayed several positive and negative closures. The gravity and magnetic lineaments were depicted and superimposed on the tectonic map of the study area. The rose diagram showed that the dominant orientation of the gravity and magnetic lineaments was toward NE-SW.
Mathematical Modeling of Photovoltaic Cell

Solar energy has been looked upon as a serious source of energy for many years because of the vast amounts of energy that are made freely available, if harnessed by modern technology. It is considered as 'Renewable Energy' because the technology used to convert the sun's power into electricity does not produce smoke & tapping the sun's energy does not usually destroy the environment. Electricity can be produced directly from photovoltaic (PV) cells. These cells exhibit the “photovoltaic effect” i.e. when sunshine hits the PV cell, the photons of light excite the electrons in the cell and cause them to flow, generating electricity. Each solar cell has a point at which the current (I) and voltage (V) output from the cell result in the maximum power output of the cell. Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of. Various approaches have been proposed to extract the maximum power from mismatched PV array. This paper represents the mathematical modelling of PV cell and also observes the effect of changing radiation on PV cell with constant temperature.
A Certificateless Ring Signature Scheme with High Efficiency in the Random Oracle Model

Ring signature is a kind of digital signature which can protect the identity of the signer. Certificateless public key cryptography not only overcomes key escrow problem but also does not lose some advantages of identity-based cryptography. Certificateless ring signature integrates ring signature with certificateless public key cryptography. In this paper, we propose an efficient certificateless ring signature; it has only three bilinear pairing operations in the verify algorithm. The scheme is proved to be unforgeable in the random oracle model.
N ov 2 01 8 An extending strategy based on TENO framework for hyperbolic conservation laws

Recently, the targeted ENO (TENO) schemes give a novel framework to keep optimal high-order spatial reconstruction wherever discontinuity is deemed to be vanished, including at smooth critical points, and to avoid oscillations by completely removing stencils crossing discontinuities. Moreover, the smoothness measurement of TENO schemes is in fact acting as shock-detectors, which are capable for distinguishing discontinuities and smooth critical points. Following the idea of a recent improvement, i.e. TENO-NA, the shock-detection and stencil-selection are completely separated in this work. Higher-order polynomials using neighbouring points of the standard five-point TENO scheme are applied for achieving higher-order accuracy without significantly increasing computation cost, by exploring the neighbouring smoothness measurements. In this work, seventh-order spatial accuracy is achieved, and the computational complexity is similar to that of the five-point TENO scheme. Especially, the presented method introduces new flexibility in constructing high-order numerical methods. Numerical results are given to show the shock-capturing and wave-resolving capabilities.
Changes in the bacterial community composition of different habitats along a polluted river (Suquía River, Cordoba, Argentina)

The objective of the present study was to investigate the influence of environmental conditions on the bacterial community composition in water, sediment and riparian soil during different water flow periods. For this purpose, samples of three habitats (water, sediment and riparian soil) were collected from five polluted sites and one reference site along the Suquia River during high and low water flow periods. The pH, dissolved oxygen, conductivity and water temperature were measured "in situ", with total organic carbon content, nitrate and ammonia concentration being evaluated for all samples. In addition, pH, conductivity and total N were determined in the sediment and riparian soil samples, and the bacterial community composition of water, sediments and riparian soil samples was monitored using restriction fragment length polymorphism of the 16S rRNA gene. The results showed that the bacterial community composition of water was different from that of sediments or riparian soil. A redundancy analysis indicated that the changes in the bacterial community composition in the Suquia River were primarily correlated with variations in dissolved oxygen, conductivity and pH. The water bacterial community composition was very variable among sites and water flow periods, while that of sediments differed according to the water flow period, which was associated with temperature variation. Lastly, in riparian soil, differences were found in the bacterial community composition of the sites located before and after Cordoba city. Our findings suggest distinct distribution patterns in the bacterial community compositions of the three habitats evaluated.
Multipolar Ferrite Assisted Synchronous Reluctance machines : a general design approach

The design of multipolar Ferrite Assisted Synchronous Reluctance (FASR) machines is formalized via a two steps procedure. At first one rectified machine pole is analyzed and key figures of merit are expressed in equations and discussed to derive general guidelines for high performance designs. Then, multipolar rotating machines are modeled as the combination of multiple rectified poles within a stack cylinder having constrained outer dimensions. It is demonstrated that, at given output torque, the number of poles can be optimized either to minimize the Joule loss or to minimize the remanence of the ferrite magnets. The design approach is both FEA and experimentally tested on a prototype FASR machine, rated about 800 Nm at 168 rpm. The prototype has been designed for direct drive lift applications, showing similar performances, if fairly compared to the ones of previous solutions based on rare-earth magnets.
Graft Composition and Post-Thawing Cell Viability Influence the Hematopoietic Recovery in Autologous Hematopoietic Stem Cell Transplantation

Objective: We investigated the influence of graft composition and post-thawing cell viability on the hematopoietic recovery of patients undergoing Autologous Hematopoietic Stem Cell Transplantation (ASCT). Methods: Data relative to 146 ASCT procedures performed in 134 patients were examined. The doses of CD34+ cells and parameters related to the grafts’ composition (white blood cell – WBC, neutrophil and platelet -PLT concentrations) were correlated to the number of days for neutrophil and platelet engraftment. Moreover, patients were grouped according to the values of post-thawing total nucleated cell (TNC) and CD34+ cell viability (as lower of higher than median values of the entire series) and hematopoietic recovery was accordingly evaluated. Results: The CD34+ cell dose significantly predicts both neutrophil and PLT engraftment. Patients with low TNC viability had longer time to neutrophil engraftment, while patients with low CD34+ cell viability exhibited longer time to both neutrophil and PLT engraftment. High WBC or neutrophil concentrations in the graft were associated with low TNC viability. In addition, we found an inverse correlation between CD34+ cell viability and graft PLT concentration. Conclusions: Our findings suggest that the platelet content in apheresis products is a critical issue, with an impact on CD34+ cell viability and hematopoietic recovery after ASCT. The apheresis products containing high amounts of PLT should be evaluated for PLT removal before freezing.
Fossil methane source dominates Cariaco Basin water column methane geochemistry

Natural radiocarbon measurements on methane (14C‐CH4) extracted from the Cariaco Basin water column show that 98% of the methane in Cariaco Basin waters is derived from fossil (radiocarbon‐free) sources. Previous work on Cariaco Basin methane (CH4) considered only a diagenetic sediment source. Similar measurements of sediment 14C‐CH4 indicate that sediment CH4 is produced from modern particulate material; thus the sediment and water column CH4 have distinct sources. Using time‐dependent CH4 geochemical box models which include a fossil seep CH4 source term, we estimate 1) 0.024–0.028 Tg y−1 of seep CH4 are added to the Cariaco Basin water column, 2) the water column CH4 will reach a steady‐state concentration by the year 2065, and 3) the seep CH4 inputs possibly began in 1967, following the July 30 Caracas earthquake. Oxidizing this CH4 to dissolved inorganic carbon does not appear to affect Cariaco Basin 14C chronologies.
Disjoint paths in geometric graphs

Disjoint Paths in Geometric Graphs by Daniel Mazzella Dr. Laxmi P. Gewali, Examination Committee Chair Professor of Computer Science University of Nevada, Las Vegas Construction of the shortest paths connecting two given nodes in a geometric graph is the quintessential problem in computational geometry. We consider several variations of this problem with applications that include robotics. Geographic Information Systems, and sensor networks. The first problem we address is the development of an efficient algorithm for constructing a pair of short node-disjoint paths connecting start and target nodes. The second problem investigated is the development of efficient algorithms for constructing narrow and in-range broadcast corridors in triangulated geometric graphs. Finally, we consider the development of an approximation algorithm for constructing reduced overlap trees in three-colored geometric graphs. Theoretical analysis and a detailed experimental investigation of the proposed algorithms are also presented.
Asymptotic Behaviour of the Fractional Heston Model

We consider here the fractional version of the Heston model originally proposed by Comte, Coutin and Renault. Inspired by some recent ground-breaking work by Gatheral, Jaisson and Rosenbaum, who showed that fractional Brownian motion with short memory allows for a better calibration of the volatility surface (as opposed to the classical econometric approach of long memory of volatility), we provide a characterisation of the short- and long-maturity asymptotics of the implied volatility smile. Our analysis reveals that the short-memory property precisely provides a jump-type behaviour of the smile for short maturities, thereby fixing the well-known standard inability of classical stochastic volatility models to fit the short-end of the volatility skew.
Children's cognitive processing of abuse as described in investigative interviews.

A great deal of research has examined ways in which investigative interviewers can elicit accurate information from children. More recently, research has studied children’s own thoughts or comprehension of abuse, and how these types of statements relate to disclosure, others’ perceptions of child witnesses, and psychological trauma. However, little research has investigated multiple types of children’s thoughts about abuse as they occur in an actual investigative interview. The current study examined seven types of statements children made about their abuse in a sample of 86 transcripts of investigative interviews conducted by Child Protective Services and a police department in a mid-sized Ontario city. Children interviewed ranged from 4to 17-years-of-age, with approximately equal numbers of males and females. Type of abuse disclosed in the interviews ranged from verbal abuse to sexual abuse. Two coders independently coded each transcript for seven statement types: expected consequences of disclosure, actual consequences of disclosure, minimization, justification for either self, perpetrator, or other, and blame. Whether the statements were elicited by an interviewer prompt or mentioned spontaneously by the child was also coded. Results demonstrated that children blamed the perpetrator more than any other statement type, consistent with previous research. Analyses also revealed a significant relationship between abuse type and children’s statements, and alleged perpetrator and children’s statements. Results from the current study have implications for disclosure, treatment of psychological trauma, and how parents, social workers, police officers, attorneys, and judges view children’s statements.
