ENERGY USE OF FISHING VESSELS OPERATING IN TASMANIA
Authors: Bishop A , Chin C K H , Thomas G
Published: October 2019

This paper investigated the fuel consumption of fishing vessels operating within the southern rock-lobster fishery and the south-eastern shark and scalefish fishery in Tasmanian waters. This was undertaken by sending a questionnaire to operators surveying different vessels and estimating the vessels’ efficiency. The estimated yearly efficiency was checked using a one sided t-test and a 95% confidence interval. Using this efficiency the fuel consumption for the 2011 calendar year for southern rock lobster and SESSF long-line vessels was estimated to be between 1.12 to 1.6 ML and between 0.70 to 0.80 ML respectively. To reduce this fuel consumption, different engineering solutions such as removal of bilge keels, service speed reduction and addition of bulbous bow were investigated, and it was found that vessels could reduce
their fuel consumption by 5 to 20%.

Published: October 2019

This paper presents an experimental research for the assessment of pressure field on the bottom of a mono-hedral hard chine hull at high relative speed. Tests have been performed in rough sea for two wave lengths at Fn ranging from 0.79 to 1.46. The measured pressures have been analysed in time and in frequency domain. The pressure distribution along a rectangular panel of the hull bottom has been identified. The comparison of measured values and those ones provided by Classification Societies has been performed and pressure results have been used to investigate the interactions between the fluid and the craft structure. The elastic behaviour of different bottom panels is analysed, and the scantling of a typical bottom panel, made from four materials, have been calculated, in order to investigate the structural dynamic behaviour.
THE DEVELOPMENT OF A LINEAR INDUCTION MOTOR AS A MARINE PROPULSION SYSTEM
Authors: Geor M , Hooper S , Tamakai S , Taylor A P R
Published: October 2019

The Linear Induction Motor (LIM) has been employed as an actuator in conveyers and more recently aircraft launches, and some work has been done on LIMs with a curved secondary reaction plate. This paper presents a working model of a marinised LIM-boat system, with underwater stator operating the hull of a boat which acts as reaction plate. The LIM stator is shown to propel the boat through the water, and that with certain reaction plate metals it will track over the stator coils and therefore be controllable in both direction and speed. Test results for differing coils and reaction plate combinations are provided.
A VARIABLE-GEOMETRY TRIMARAN - Technical Note
Authors: Witt D C
Published: October 2019

Technical Note - To travel fast with reasonably low power requires a vessel to be long and narrow. The requirement for static stability means that unless ballast is used such a vessel will be restricted in vertical height, with adverse consequences for bending strength and for cargo or passenger space. If stability at cruising speed were achieved by the use of automatically controlled fins or rudders, the problem might be solved. Stability at low speeds or when stationary could be got by lowering a pair of outer hulls to form a trimaran. The paper describes a trial design and tests on a scale model.
A THREE-DIMENSIONAL INVERSE METHOD FOR THE DESIGN OF SAILS
Authors: Pilate J P , Gerhardt F C , Norris S E , Flay R G J
Published: October 2019

This paper investigates an inverse process for the design of yacht sails. The method is described and then applied to the design of optimal sails for a specific yacht. The proposed inverse method generates the three-dimensional shapes of a headsail and mainsail from prescribed loading (i.e. differential pressure) distributions, accounts for the effect of the sea surface, and also simulates the twist and shear of the incoming flow. The uncoupled iterative routine solves a sequence of analysis steps so that the sail shapes are deformed in such a way that their updated loading distributions converge to the specified target distributions. During each iteration equations derived from two-dimensional Thin Aerofoil Theory, calculate a geometry correction from the difference between the current and target loading distributions. This correction is applied to the sail geometry, and a vortex lattice method code calculates the updated three-dimensional differential pressure distributions, which are again compared to the target distributions. Usually only five iterations are required to converge to sail shapes that have the target loading distributions. The inverse method has been validated by inverting the traditional way of analysing sails, i.e. a set of sails with known geometry has been analysed and the loading distributions on the headsail and mainsail were calculated. These distributions were then used as an input for the inverse code. It was
found that the difference in camber between the original sails and the calculated geometry is less than 0.01% of camber at the mid-span of the sails. The second part of the paper presents two methods for the design of optimal sails for a yacht. One of the methods uses the more traditional analysis approach, while the other employs the inverse method described in this paper. The optimisation is performed for a Transpac 52 yacht in 12 knots (6.5 m/s) of true wind speed to obtain the best velocity made good. Results from both methods are presented and discussed and it is found that the results in terms of boat speed are similar although the trims differ slightly. However, the new inverse method is approximately nine times faster than the traditional analysis approach.
SENSOR FAULT DETECTION AND SIGNAL IMPROVEMENT USING PREDICTIVE FILTERS
Authors: Kerhascoët H , Merien P , Laurent J , Senn E , Hauville F
Published: October 2019

Navigation systems used in racing boats require sensors to be more and more sophisticated in order to obtain accurate information in real time. To meet the need for accuracy of the surface speed measurement, the mechanical sensor paddle wheel has been replaced by the ultrasonic sensor. This ultrasonic sensor measures the water speed precisely and with very good linearity. Furthermore, by its principle of operation, it measures the water flow several centimetres from the sensor, which puts it outside the boundary layer, the region close to the hull where the flow is disturbed. However, this sensor has several drawbacks: it is quite sensitive and if the flow contains too many air bubbles, the sensor picks them up, which can happen quite frequently on boat with a planing hull. Another limitation of this sensor is its low frequency measurement rate. In this paper, we explain the techniques used based on Kalman filters to address these shortcomings, firstly by identifying the inaccurate measurements caused by inadvertent dropouts, then by improving the useful sensor frequency with GNSS data fusion.

Detecting DDoS Attacks Using Polyscale Analysis and Deep Learning
Authors: Ghanbari Maryam , Kinsner Witold
Published: October 2019

Distributed denial-of-service (DDoS) attacks are serious threats to the availability of a smart grid infrastructure services because they can cause massive blackouts. This study describes an anomaly detection method for improving the detection rate of a DDoS attack in a smart grid. This improvement was achieved by increasing the classification of the training and testing phases in a convolutional neural network (CNN). A full version of the variance fractal dimension trajectory (VFDTv2) was used to extract inherent features from the stochastic fractal input data. A discrete wavelet transform (DWT) was applied to the input data and the VFDTv2 to extract significant distinguishing features during data pre-processing. A support vector machine (SVM) was used for data post-processing. The implementation detected the DDoS attack with 87.35% accuracy.
Critical Condition Detection Using Lion Hunting Optimizer and SVM Classifier in a Healthcare WBAN
Authors: Kathuria Madhumita , Gambhir Sapna
Published: October 2019

A timely critical condition detection and early notification are two essential requirements in a healthcare wireless body area network for the correct treatment of patients. However, most of the systems have limited capabilities and so could not detect the exact condition in a precise time interval. In addition to these it needs a reduction in the false alert rate, as issuing alerts for the deviation in each incoming packet increases the false alert rate and these false alerts consume more network resources. In order to fulfill the above-mentioned requirements, a dynamic alert system has been designed in this regard to make it more efficient, also, a new kind of hybridization approach is being introduced to it with the additive support of a nature-inspired optimization strategy named Lion Hunting and a machine-learning technique called support vector machine. The simulation is done using a network simulator NS-2.35, and the proposed alerting system outperforms others.

Published: October 2019

Background: This study aims to define the incidence and risk factors of both emergence agitation and hypoactive emergence in adult patients and substance-dependent patients following general anesthesia to elaborate on the risk factors and precise management of them. Methods: The study recruited 1,136 adult patients who received elective surgeries under general anesthesia for this prospective observational study. Inadequate emergence was determined according to the Richmond Agitation-Sedation Scale (RASS). Emergence agitation was defined as a RASS ≥ +1 point, and hypoactive emergence was defined as a RASS ≤ –2 points. Subgroup analyses were then conducted on patients with substance dependence.Results: Inadequate emergence in the post-anesthesia care unit (PACU) occurred in 20.3% of patients, including 13.9% with emergence agitation and 6.4% with hypoactive emergence. Ninety-five patients had a history of substance dependence. Compared to divorced patients, never-married and presently married patients, who underwent gynecological and thoracic surgeries, had a lower risk of agitation. Neurologic disorders, intraoperative blood loss, intraoperative morphine, and PACU analgesic drug administration were associated with increased agitation risk. Hypertension and psychological disorders, intraoperative opioids, and PACU Foley catheter fixation were associated with increased hypoactive emergence risk. Substance-dependent patients had higher risk for agitation (21.1%, P = 0.019) and hypoactive emergence (10.5%, P = 0.044). Conclusions: Inadequate emergence in PACU following general anesthesia is a significant problem correlated with several perioperative factors. Patients with a history of substance dependence appear to be more at risk of inadequate emergence than the general population.
Oral Acyclovir for Severe Hand, Foot and Mouth Disease
Authors: Damle Dhananjay K
Published: October 2019

Hand, foot and mouth disease (HFMD), an acute viral illness caused by coxsackieviruses or enteroviruses, is predominantly encountered in children under 10 years of age. Although it is usually self-resolving, there are a few rare cases which have an extremely aggressive clinical presentation and need to be treated on a priority. Many affected children present with florid or unusual lesions; are highly febrile, with high irritability or listlessness; and also refuse to eat. Such cases could be considered as severe ones. With no specific effective antiviral available to tackle HFMD cases, acyclovir may be used in severe cases for its antiviral effect. We describe three such cases of HFMD in children, treated with oral acyclovir, with gratifying results.
Effect of random time changes on Loewner hulls
Authors: Kobayashi Kei , Lind Joan , Starnes Andrew
Published: October 2019

Loewner hulls are determined by their real-valued driving functions. We study the geometric effect on the Loewner hulls when the driving function is composed with a random time change, such as the inverse of an

\alpha

-stable subordinator. In contrast to SLE, we show that for a large class of random time changes, the time-changed Brownian motion process does not generate a simple curve. Further we develop criteria which can be applied in many situations to determine whether the Loewner hull generated by a time-changed driving function is simple or non-simple. To aid our analysis of an example with a time-changed deterministic driving function, we prove a deterministic result that a driving function that moves faster than

at^r

for

r \in (0, 1/2)

generates a hull that leaves the real line tangentially.
Trends and source apportionment of aerosols in Europe during 1980–2018
Authors: Yang Yang , Lou Sijia , Wang Hailong , Wang Pinya , Liao Hong
Published: October 2019

Abstract. Aerosols have significantly affected health, environment and climate in Europe. Aerosol concentrations have been declining since 1980s in Europe, mainly owing to the reduction of local aerosol and precursor emissions. Emissions from other source regions of the world, which have been changing rapidly as well, may also perturb the historical and future trends of aerosols and change their radiative impact in Europe. This study examines trends of aerosols in Europe during 1980–2018 and quantify contributions from sixteen source regions using the Community Atmosphere Model version 5 with an Explicit Aerosol Source Tagging technique (CAM5-EAST). The simulated near-surface total mass concentration of sulfate, black carbon and primary organic carbon had a 62 % decrease during 1980–2018, of which the majority was contributed by reductions of local emissions in Europe and 8 %–9 % was induced by the decrease in emissions from Russia–Belarus–Ukraine. With the decreases in the fractional contribution of local emissions, aerosols transported from other source regions are increasingly important to air quality in Europe. During 1980–2018, the decrease in sulfate loading leads to a warming effect of 2.0 W m−2 in Europe, with 12 % coming from changes in non-European sources, especially from North America and Russia–Belarus–Ukraine. According to the Shared Socioeconomic Pathways (SSP) scenarios, contributions to the sulfate radiative forcing over Europe from both European local emissions and non-European emissions would decrease at a comparable rate in the next three decades, suggesting that future changes in non-European emissions are as important as European emissions in causing possible regional climate change associated with aerosols in Europe.

Abstract. On 13 October 2017, the Tropospheric Monitoring Instrument
(TROPOMI) was launched on the Copernicus Sentinel-5
Precursor satellite in a sun-synchronous orbit. One of the
mission's operational data products is the total column
concentration of carbon monoxide (CO), which was released
to the public in July 2018. The current TROPOMI CO
processing uses the HITRAN 2008 spectroscopic data with
updated water vapor spectroscopy and produces a CO data
product compliant with the mission requirement of 10 %
precision and 15 % accuracy for single soundings.
Comparison with ground-based CO observations of the Total
Carbon Column Observing Network (TCCON) show systematic
differences of about 6.2 ppb and single-orbit
observations are superimposed by a significant striping
pattern along the flight path exceeding 5 ppb. In this
study, we discuss possible improvements of the CO data
product. We found that the molecular spectroscopic data
used in the retrieval plays a key role for the data
quality where the use of the Scientific Exploitation of
Operational Missions – Improved Atmospheric Spectroscopy
Databases (SEOM-IAS) and the HITRAN 2012 and 2016 releases
reduce the bias between TROPOMI and TCCON due to improved
CH4 spectroscopy. SEOM-IAS achieves the best
spectral fit quality (root-mean-square, rms,
differences between the simulated and measured spectrum)
of 1.5×10-10 mol s−1 m−2 nm−1 sr−1 and reduces the bias between TROPOMI and TCCON to
3.4 ppb, while HITRAN 2012 and HITRAN 2016 decrease the
bias even further below 1 ppb. HITRAN 2012 shows the
worst fit quality (rms = 2.5×10-10 mol s−1 m−2 nm−1 sr−1) of the tested cross sections
and furthermore introduces an artificial bias of about
-1.5×1017 molec cm−2 between TROPOMI CO and
the CAMS-IFS model in the Tropics caused by the H2O
spectroscopic data. Moreover, analyzing 1 year of
TROPOMI CO observations, we identified increased striping
patterns by about 16 % percent from November 2017 to
November 2018. For that, we defined a measure γ,
quantifying the relative pixel-to-pixel variation in CO in the
cross-track and along-track directions.
To mitigate this effect, we discuss two
destriping methods applied to the CO data a posteriori.
A destriping mask calculated per orbit by median filtering
of the data in the cross-track direction significantly
reduced the stripe pattern from γ=2.1 to γ=1.6.
However,
the destriping can be further improved, achieving γ=1.2 by
deploying a Fourier analysis and filtering of the
data, which not only corrects for stripe patterns in the
cross-track direction but also accounts for the
variability of stripes along the flight path.
Hypoxia in mangroves: occurrence and impact on valuable tropical fish habitat
Authors: Dubuc Alexia , Baker Ronald , Marchand Cyril , Waltham Nathan J. , Sheaves Marcus
Published: October 2019

Abstract. Intertidal mangrove forests are harsh environments that
can naturally experience hypoxia in association with low tide. However, we
know relatively little about dissolved oxygen (DO) fluctuations and
DO-induced responses by fish, although DO is a fundamental water quality
parameter. This study examines DO as a potential factor regulating the
utilisation of intertidal mangrove forests by fish and consequently their
widely recognised feeding, refuge and nursery values. We deployed underwater
video cameras, coupled with DO and depth loggers, in a mangrove forest to
record changes in fish assemblages in response to tidal variations in DO and
other associated environmental parameters. Our results indicate that DO
underwent extreme tidal fluctuations, reaching levels as low as 14 %
saturation. As DO was identified as a significant factor for explaining
variability in fish assemblage composition, we further investigated fish
responses to DO fluctuations. Higher taxonomic richness and frequencies of
occurrence were observed once DO reached 70 %–80 % saturation. More
detailed examination revealed species-specific responses. Three distinct
patterns of mangrove utilisation in response to DO were identified, driven
by apparent taxa's behavioural DO avoidance thresholds. Most taxa did not
display any behavioural avoidance, including presence at the lowest DO
levels, while other taxa were not observed either below 50 %–60 %
saturation or below 70 %–80 % saturation. This implies that tidal
migrations, often observed in intertidal environments, could be the result
of differential DO tolerances and are not simply initiated by changes in water
depth. Taxa remaining in the mangrove forest even at low DO were on average
more frequently observed than the other taxa and were mostly species
commonly associated with mangrove habitats. This suggests that being adapted
to withstand low DO might be an important condition for using mangrove habitats
extensively. The need of being tolerant to low DO could constrain fish
utilisation and explain the relatively low species richness often observed
in other intertidal mangrove forests.
Modeling forest plantations for carbon uptake with the LPJmL dynamic global vegetation model
Authors: Braakhekke Maarten C. , Doelman Jonathan C. , Baas Peter , Müller Christoph , Schaphoff Sibyll , Stehfest Elke , van Vuuren Detlef P.
Published: October 2019

Abstract. We present an extension of the dynamic global vegetation model, Lund–Potsdam–Jena Managed Land (LPJmL), to
simulate planted forests intended for carbon (C) sequestration. We implemented three functional types to simulate plantation trees in temperate, tropical, and boreal climates. The parameters of these functional types were optimized to fit target growth curves (TGCs). These curves represent the evolution of stemwood C over time in typical productive plantations and were derived by combining field observations and LPJmL estimates for equivalent natural forests. While the calibrated model underestimates stemwood C growth rates compared to the TGCs, it represents substantial improvement over using natural forests to represent afforestation. Based on a simulation experiment in which we compared global natural forest versus global forest plantation, we found that forest plantations allow for much larger C uptake rates on the timescale of 100 years, with a maximum difference of a factor of 1.9, around 54 years. In subsequent simulations for an ambitious but realistic scenario in which 650 Mha (14 % of global managed land, 4.5 % of global land surface) are converted to forest over 85 years, we found that natural forests take up 37 PgC versus 48 PgC for forest plantations. Comparing these results to estimations of C sequestration required to achieve the 2 ∘C climate target, we conclude that afforestation can offer a substantial contribution to climate mitigation. Full evaluation of afforestation as a climate change mitigation strategy requires an integrated assessment which considers all relevant aspects, including costs, biodiversity, and trade-offs with other land-use types. Our extended version of LPJmL can contribute to such an assessment by providing improved estimates of C uptake rates by forest plantations.
Short communication: A semi-automated method for rapid fault slip analysis from topographic scarp profiles
Authors: Wolfe Franklin D. , Stahl Timothy A. , Villamor Pilar , Lukovic Biljana
Published: October 2019

Abstract. Here, we introduce an open source, semi-automated, Python-based graphical user interface (GUI) called the Monte Carlo Slip Statistics Toolkit (MCSST) for estimating dip slip on individual or bulk fault datasets. Using this toolkit, profiles are defined across fault scarps in high-resolution digital elevation models (DEMs) and then relevant fault scarp components are interactively identified (e.g., footwall, hanging wall, and scarp). Displacement statistics are calculated automatically using Monte Carlo simulation and can be conveniently visualized in Geographic Information Systems (GIS) for spatial analysis. Fault slip rates can also be calculated when ages of footwall and hanging wall surfaces are known, allowing for temporal analysis. This method allows for rapid analysis of tens to hundreds of faults in rapid succession within GIS and a Python coding environment. Application of this method may contribute to a wide range of regional and local earthquake geology studies with adequate high-resolution DEM coverage, both regional fault source characterization for seismic hazard and/or estimating geologic slip and strain rates, including creating long-term deformation maps. ArcGIS versions of these functions are available, as well ones that utilize free, open source Quantum GIS (QGIS) and Jupyter Notebook Python software.
Hydrograph separation: an impartial parametrization for an imperfect method
Authors: Pelletier Antoine , Andréassian Vazken
Published: October 2019

Abstract. This paper presents a new method for hydrograph separation. It is well-known that all hydrological methods aiming at separating streamflow into baseflow and quickflow present large imperfections, and we do not claim to provide here a perfect solution. However, the method described here is at least (i) impartial in the determination of its two parameters (a quadratic reservoir capacity and a response time), (ii) coherent in time (as assessed by a split-sample test) and (iii) geologically coherent (an exhaustive validation on 1,664 French catchments shows a good match with what we know of France's hydrogeology). Last, an R package is provided to ensure reproducibility of the results presented.
Baroclinic and barotropic instabilities in planetary atmospheres - energetics,
equilibration and adjustment
Authors: Read Peter , Lewis Neil , Kennedy Daniel , Scolan Hélène , Tabataba-Vakili Fachreddin , Wang Yixiong , Wright Susie , Young Roland
Published: October 2019

Abstract. Baroclinic and barotropic instabilities, are well known as the mechanisms responsible for the production of the dominant energy-containing eddies in the atmospheres of the Earth and several other planets, as well as the Earth's oceans. Here we consider insights provided by both linear and nonlinear instability theories into the conditions under which such instabilities may occur, with reference to forced and dissipative flows obtainable in the laboratory, in simplified numerical atmospheric circulation models and in the planets of our Solar System. The equilibration of such instabilities is also of great importance in understanding the structure and energetics of the observable circulation of atmospheres and oceans. Various ideas have been proposed concerning the ways in which baroclinic and barotropic instabilities grow to large amplitude and saturate, whilst also modifying their background flow and environment. This remains an area that continues to challenge theoreticians and observers, though some progress has been made. The notion that such instabilities may act under some conditions to adjust the background flow towards a critical state is explored here in the context of both laboratory systems and planetary atmospheres. Evidence for such adjustment processes is found relating to baroclinic instabilities under a range of conditions where the efficiency of eddy and zonal mean heat transport may mutually compensate to maintain a nearly invariant thermal structure in the zonal mean. In other systems, barotropic instabilities may efficiently mix potential vorticity to result in a flow configuration that is found to approach a marginally unstable state with respect to Arnol'd's second stability theorem. We discuss the implications of these findings and identify some outstanding open questions.

Published: October 2019

Meeting the diverse and various needs of learners, who come from different cultural and social environments, imposes changes in a modern education system through the implementation of new teaching approaches and practices, such as differentiated instruction. This literature review examines 16 studies regarding differentiated instruction in higher education which have taken place during the last decade. The results of the research revealed that differentiated instruction contributes to mobilizing preservice teachers, improving their performance and developing positive attitudes and beliefs of trainees and educators in higher education. There is also a need for further research regarding the effectiveness of the implementation of differentiated instruction in higher education, especially in Greece, where no relevant research has been conducted, compared to the international field.
Harvest chronological planning using a method based on satellite-derived vegetation indices and artificial neural networks
Authors: Taghizadeh Sepideh , Navid Hossin , Adiban Reza , Maghsodi Yasser
Published: October 2019

Aim of study: Wheat appropriate harvest date (WAHD) is an important factor in farm monitoring and harvest campaign schedule. Satellite remote sensing provides the possibility of continuous monitoring of large areas. In this study, we aimed to investigate the strength of vegetation indices (VIs) derived from Landsat-8 for generating the harvest schedule regional (HSR) map using Artificial Neural Network (ANN), a robust prediction tool in the agriculture sector.Area of study: Qorveh plain, Iran.Material and methods: During 2015 and 2016, a total of 100 plots was selected. WAHD was determined by sampling of plots and specifying wheat maximum yield for each plot. The strength of eight Landsat-8 derived spectral VIs (NDVI, SAVI, GreenNDVI, NDWI, EVI, EVI2, CVI and CIgreen) was investigated during wheat growth stages using correlation coefficients between these VIs and observed WAHD. The derived VIs from the required images were used as inputs of ANNs and WAHD was considered as output. Several ANN models were designed by combining various VIs data.Main results: The temporal stage in agreement with dough development stage had the highest correlation with WAHD. The optimum model for predicting WAHD was a Multi-Layer Perceptron model including one hidden layer with ten neurons in it when the inputs were NDVI, NDWI, and EVI2. To evaluate the difference between measured and predicted values of ANNs, MAE, RMSE, and R2 were calculated. For the 3-10-1 topology, the value of R2 was estimated 0.925. A HSR map was generated with RMSE of 0.86 days.Research highlights: Integrated satellite-derived VIs and ANNs is a novel and remarkable methodology to predict WAHD, optimize harvest campaign scheduling and farm management.
Mudharabah Deposits Among Conventional Bank Interest Rates, Profit-Sharing Rates, Liquidity and Inflation Rates
Authors: Doktoralina Caturida Meiwanto , Nisha Fikki Mutarotun
Published: October 2019

This paper aims to examine the effect of conventional bank interest rates (CBIR), profit-sharing rates (PS), the level of liquidity proxied in the finance-to-deposit ratio (FDR) and the inflation rate (IR) against mudharabah deposits (MDs). The sample comes from eight Islamic public banks registered in the Financial Services Authority (OJK) and Bank Indonesia (BI) for the period from 2013 to 2017. The research uses a data panel regression analysis using EViews 8 to test the significance of tribal-level influence on conventional bank interest, profit-sharing growth rate, liquidity level and inflation rate. The results provide evidence that conventional interest rates do not affect MDs; the profit-sharing rate has a significant positive effect on MDs; the FDR has a positive effect on MDs, and the IR does not affect MDs. The results can increase our understanding of the variables that affect the volume of MDs. The results of this research have practical implications for people who will invest, giving them a better basis for making deposit and investment decisions by looking at interest rates and profit-sharing systems that are in line with Islamic investment principles that apply no uncertainty (Garar), interest (Riba) and gambling (Maisir) investments to cover all aspects of life (way of life).
Evaluation of an HIV-Related Workshop for Adolescents at a Secondary School in Germany
Authors: Davis Burt , Grosser Katharina
Published: October 2019

This study set out to establish to what extent an HIV-related awareness workshop involving German adolescents at a secondary school in Brandenburg can help to increase knowledge levels about this disease. Only a few studies have explored what German youths know about HIV, with none so far evaluating a workshop aimed at increasing HIV-related knowledge levels among this cohort. In a pre-test post-test design, changes in participants’ knowledge levels related to the risk of HIV transmission associated with different types of exposures or behaviors such as unprotected sex, mother-to-child-transmission, blood transfusions, and shaking hands were assessed. Previous studies have shown that German youths lack knowledge in this regard.

From pre-test to post-test, there was a statistically significant increase in knowledge levels about the risk of HIV transmission. However, knowledge levels about the risk of HIV transmission was relatively low. An average of 59.2% questions were answered correctly at pre-test vs. 68.1% of questions at post-test. The present study underlines that an awareness workshop can be a useful tool to improve knowledge levels about the risk of HIV transmission among youths. However, the results also revealed that there is still some work to be done to educate young Germans about the basic facts around HIV/AIDS. Although HIV incidence rate in Germany has been slightly decreasing, there is a growing number of new infections among people who are unaware of their HIV status – while research shows that youths in this country are seemingly complacent about the danger of HIV/AIDS, and often do not use condoms during sex.
The Remarriage of Reason and Experience in Kant’s Critique of Pure Reason
Authors: McQuillan J. Colin ,   Philosophy Documentation Center
Published: October 2019

This article argues that Immanuel Kant recreates in his critical philosophy one of the most distinctive features of Christian Wolff’s rationalism—the marriage of reason and experience (connubium rationis et experientiae). The article begins with an overview of Wolff’s connubium and then surveys the reasons some of his contemporaries opposed the marriage of reason and experience, paying special attention to the distinctions between phenomena and noumena, sensible and intellectual cognition, and empirical and pure cognition that Kant employs in his inaugural dissertation On the Form and Principles of the Sensible and the Intelligible World (1770). The final section of the article argues that, in the Critique of Pure Reason (1781/1787), Kant rejects the anticonnubialist positions he defended in his inaugural dissertation and introduces a new account of the relation between reason and experience that recreates Wolff’s connubium within the context of his critical philosophy.
Classification of Disjunctivism about the Phenomenology of Visual Experience
Authors: Niikawa Takuya ,   Philosophy Documentation Center
Published: October 2019

This paper proposes a classificatory framework for disjunctivism about the phenomenology of visual perceptual experience. Disjunctivism of this sort is typically divided into positive and negative disjunctivism. This distinction successfully reflects the disagreement amongst disjunctivists regarding the explanatory status of the introspective indiscriminability of veridical perception and hallucination. However, it is unsatisfactory in two respects. First, it cannot accommodate eliminativism about the phenomenology of hallucination. Second, the class of positive disjunctivism is too coarse-grained to provide an informative overview of the current dialectical landscape. Given this, I propose a classificatory framework which preserves the positive-negative distinction, but which also includes the distinction between eliminativism and non-eliminativism, as well as a distinction between two subclasses of positive disjunctivism. In describing each class in detail, I specify who takes up each position in the existing literature, and demonstrate that this classificatory framework can disambiguate some existing disjunctivist views.
Home and Our Need For It
Authors: Toner Christopher ,   Philosophy Documentation Center
Published: October 2019

Aviezer Tucker claims that “home-searching is a basic trait of being human,” yet as a rule the concept of home has not been central in recent Anglophonic ethics. I will argue, though, that giving an important place to the concept of home should be far more common. I begin by showing that ‘home’ is a particular kind of concept, what Daniel Russell calls a model concept. I then turn to the main task of the paper, the construction of a theoretical model of ‘home,’ bringing various treatments of the concept—linguistic, literary, and social scientific—into reflective equilibrium. Security, comfort, and belonging will turn out to be key features of the model. I close by noting some ways in which the concept of home is much more important to moral theory, and especially to virtue ethics, than has generally been recognized. The title refers both to our need for home, as humans, and to our need for ‘home,’ as moral theorists.
Using Coordinated Measurement With Future Teachers to Connect Multiplication, Division, and Proportional Relationships

Published: October 2019

We report results from a mathematics content course intended to help future teachers form a coherent perspective on topics related to multiplication, including whole-number multiplication and division, fraction arithmetic, proportional relationships, and linear functions. We used one meaning of multiplication, based in measurement and expressed as an equation, to support future teachers' understanding of these topics. We also used 2 types of length-based math drawings–double number lines and strip diagrams–as media with which to represent relationships among quantities and solve problems. To illustrate the promise of this approach, we share data in which future secondary mathematics teachers generated and explained without direct instruction sound methods for dividing by fractions and solving proportional relationships. The results are noteworthy, because these and other topics related to multiplication pose perennial challenges for many teachers.

O papel do cão como um hospedeiro definitivo de parasitoses intestinais com potencial zoonótico tem sido largamente reconhecido como um problema de saúde pública. Este trabalho analisou a prevalência e distribuição de enteroparasitas em fezes de cães de rua de oito cidades dos diferentes biomas nordestinos, com interesse de investigar a contaminação ambiental por enteroparasitas zoonóticos. 340 amostras fecais foram coletadas nos municípios de João Lisboa e Raposa (Maranhão), Piripiri e Domingos Mourão (Piauí), Fortaleza (Ceará), Petrolina (Pernambuco), Paulo Afonso e Salvador (Bahia). Deste total 43,2% resultaram positivas para alguma espécie de parasita intestinal. Maiores prevalências foram encontradas por ancilostomídeos com 43,5%, seguidos por Toxocara canis com 15%, Neospora sp. com 10,2% e Cryptosporidium sp. com 8,2%. Analisando a porcentagem de positividade por enteroparasitas nos quatro biomas da região Nordeste, o bioma Mata Atlântica foi o que apresentou maior prevalência (54,9%), seguido da Amazônia (54,3%), Caatinga (40,2%) e Cerrado (31,8%). O estudo da ocorrência e distribuição desses parasitas contribui com a vigilância epidemiológica das doenças enteroparasitárias e na aplicação de programas de saúde pública e veterinária para minimizarem a possibilidade de infecção e reinfecção dos animais e a transmissão para seres humanos.

In the Brazilian semiarid region, the high temperatures in association with the high level of solar radiation and variations in the concentration of CO2 which of focus on plants may influence the physical conformation of vegetables and their growth. On the basis of the above, the objective of this work to evaluate the content of gas exchange and chlorophyll in plants typical of Caatinga, associating possible interference of the power plant Borborema thermal S/A. the study carried out in the period of 2014-2018 with botanical species in two areas of the caatinga of Paraiba. To analyze the variables used the infra Red Gas Analyzer (RGA) and the SPAD. In using SPAD equipment it was found that the species had higher SPAD value were Aspidosperma pyrifolium Mart., (SPAD=50) P300. As the analyzes of gas exchange by the LCpro+, obtained greater record in plant Aspidosperma pyrifolium Mart. In point (P400). The maximum values of E and points were recorded (P600) (E=3.44>335 mmol.H2O.m-².s-¹) and (P100) (E=3.16mmol.H2O.m-².s-¹), both second collection. The first collection the highest registered was E=2.30mmol.H2O.m-².s-¹ (P600), Ziziphus species Joazeiro. In relation of the Tukey test, it was found that the transpiration of tree species, were higher in the second collection, the range of confidence (a, b) were significantly different. It was concluded that the indexes were higher by SPAD the occasion of the 2ª collection. The Ci presented low variation between the two periods. It was so, a non-correlation between the collections and areas surveyed.
Root Canal Morphology of Mandibular Primary Molars: A Micro-CT Study
Authors: ZİYA Meryem , YÜKSEL Burcu Nihan , SARI Şaziye
Published: October 2019

Objectives: Frequency of typical and non-typical root and canal
morphology of primary teeth, which in clinical practice cannot
be detected using 2D radiographic images,
should be known by clinicians to decrease failures arising
from complexity of root canal morphologies. The
aim of this in vitro study was to evaluate morphologic variations in mandibular
primary molars’ root canal systems.

Materials and
Methods: Primary mandibular 1st
(n=17) and 2nd (n=33) molars were scanned using micro-CT. 3D root
models were obtained and root canal morphologies were evaluated according to a
modified Vertucci classification. Type 1 and Type
4 canal morphologies were evaluated as ‘normal’ and all other types and
‘non-typical’ canal morphology were evaluated as ‘abnormal’ root canal
morphology.

Results: Most common root canal morphology among mandibular
primary 1st molars were Vertucci Type 4 morphology for both mesial
and distal roots (47% and 41.2% respectively), and non-typical morphology for
both the mesial and distal roots (45.7% and 21.2% respectively) of mandibular
primary 2nd molars.

Conclusions: Wide range of morphologic variations and frequency of
non-typical morphology could be seen especially among mandibular primary 2nd
molars and use of disinfectant irrigants and root canal
fillings with high antibacterial efficacies are important in order to decrease
failures arising from these inaccessible areas.
Associations entre les symptômes dépressifs et anxieux, le soutien social, l’identité vocationnelle et l’adaptation lors de la transition secondaire-collégial1
Authors: Germain Francine , Marcotte Diane
Published: October 2019

Cette étude longitudinale vise à comparer l’effet de trois covariables, soit le soutien perçu des parents, des pairs et l’identité vocationnelle, mesurées en 1reannée collégiale sur l’adaptation, à comparer l’effet des symptômes dépressifs et anxieux mesurés en 5eannée du secondaire et en 1reannée collégiale sur l’adaptation et à identifier les effets modérateurs des trois covariables sur la relation entre la dépression et l’anxiété et l’adaptation au collège. Un échantillon de 247 étudiant·e·s inscrit·e·s en 1reannée d’un collège a complété les questionnaires autoadministrés au cours du premier semestre. L’identité vocationnelle se démarque par rapport au soutien perçu des parents et des pairs par son effet positif sur l’ensemble des domaines de l’adaptation. La présence de symptômes intériorisés demeure un facteur déterminant dans l’adaptation des nouveaux·elles collégien·ne·s. Finalement, en comparaison, les symptômes dépressifs sont liés plus fortement à l’adaptation collégiale que les symptômes anxieux.
