Science outreach improves science literacy among the public and communication skills of scientists. However, despite the array of well-documented benefits, robust outreach efforts are often absent from communities which stand to benefit the most from these initiatives. Here, we introduce “Science Fiesta,” a graduate student-led outreach initiative which utilizes cultural traditions of South Texas as a vehicle to establish self-sustaining interactions between scientists and their local community. Event assessment surveys indicated that attendees found the event both fun and educational. At the same time, graduate students who organized the event and participated in outreach reported that they strengthened a variety of professional skills important for their future careers. More importantly, the event had a substantial positive impact on enthusiasm for science outreach. Both public attendees and graduate students reported that they were likely to participate in future science outreach events, even though a majority of both groups had not been previously involved in outreach efforts. Science Fiesta is a model for a highly effective graduate student-led outreach initiative that is capable of 1) improving public scientific literacy, 2) reinforcing graduate education and career development and 3) creating a culture of science engagement within local communities.

Authors: Černý Pavel , Nesvadba Matěj , Pleninger Stanislav 
Published: October 2016

This article describes the Electronic Flight Strip System used at Václav Havel Airport Prague and presents the results of an analysis of the clearance input from ATCOs. The outcomes indicate that various clearances are frequently issued together in a common time frame, usually depending on the traffic flow structure. The focus then moves towards the implementation of the TAXI milestone into the Start-Up Manager. The used statistic methods indicate that the amount of TTOT recalculations after AOBT decreases, but not significantly. However, the accuracy of TTOT after TAXI clearance is considerably better. The mean and most common deviation of ATOT from TTOT after the implementation of TAXI milestone is -1 minute. The results are challenged and confirmed by a further analysis of the TTOT-ATOT difference regarding individual stand/RWY pairs. The results may be used to adjust the assumed taxi times.

Authors: Czachor Gabriel , Bohdziewicz Jerzy , Kawa Krzysztof 
Published: October 2016

Abstract
The usefulness of raw material obtained from oak leaves, waste from paper mass and fragments of Miscanthus was verified with regard to pellet production. A batch of pellets produced therefrom was subjected to technological shear tests with the use of prototype equipment. Also pellets produced by well-known Polish producers were tested. The suggested method of technological shear enables obtaining credible results through standardization of tests conditions. Statistical processing of results proved that there are significant differences in the values of shear strength and unit shear work obtained for both group of pellets. An experimental batch of pellets has a lower density and thus lower shear strength which limits the scope of industrial application. The research which was carried out proved that there is a strong correlation between mechanical strength and density.

Abstract
The object of the research is a technological process and technical means of cutting woody shrubs at melioration objects. The subject of the research consists of regularities and methods of execution of the process of cutting woody shrubs at melioration objects by a multirotor mower with trapezoidal knives. The aim of the research is to increase efficiency of cutting shrubs at melioration objects by applying a multi-rotor mower with trapezoidal knives. We have obtained analy tical dependences in order to determine the angle of diversion of a knife from the radial position during contact with the stem, and to calculate the reaction in the joint “knife-fixing bolt” depending on the parameters of a knife and rotor, and the distance from the centre of the knife fixing bolt to the point of contact of a knife and stem, which provides minimal impact load on the knife fixing bolt during cutting woody shrubs. We have also developed a mathematical model of the process of cutting shrubs by a multi-rotor mover with trapezoidal knives, and methods of determination of the main parameters and regimes of work of the mower cutting apparatus for cutting shrubs at melioration objects, which contain a monogram, based on the use of theoretical-experimental dependences.

Abstract
In order to accelerate the process of drying of grass mowed for hay and haylage there are numerous technological treatments: multiple tedding, raking in rolls and turning rolls, mechanical impact on green forage in the process of mowing by the use of presses and windrow scarifiers. Presently mechanical maceration of green forage with mowing is popular. Papilionaceous feed plants are subjected to windrow presses and graminacenous plants to beating working systems. Analysis of various devices for acceleration of the drying process of green forage proves that they are quite complex and expensive on account of considerable material consumption. In order to eliminate the faults in the Russian Scientific and Research Fodder Institute of Wiliams a completely different windrow scarifier for the rotary mower KR-2.4 M was developed. It has a simple structure and it serves for acceleration of field drying of mowed grass in loose rolls. The paper presents the results of the research on a mower with an experimental windrow scarifier

Published: October 2016

Abstract
Air is supplied to a milking machine installation most usually in a constant manner by supply of a small amount of air to a milking chamber of a claw or periodically to a connection pipe of a liner, which enables milk outflow to a milking pipe and improves stabilization of vacuum and limits its fluctuations. On the market of milking machines there is a new solution in the form of mouthpiece vented liners - impulseair®, where air is supplied constantly by a calibrated nozzle in the head of a liner. The objective of the paper was to analyse and assess the selected parameters of milking determined in a milking machine with a claw with fixed volume of a milking chamber (250 cm3) with mouthpiece vented liners in comparison to other solutions used for air supply in milking machines. Measurements were carried out in laboratory conditions with milking to the upper milk pipeline, at variable mass intensities of liquid flow (within 0-8 kg·min−1), for three penetrations of artificial teats (46, 48, 62 mm), at three values of the system vacuum (46, 48 and 50 kPa). A significant impact of the manner of air supply to a milking machine and remaining independent variables of an experiment on the selected milking parameters was proved with the use of a statistical analysis. It was found that a milking unit with mouthpiece vented liners, although it reduces average vacuum of suction [pss], at the same time it limits fluctuations of underpressure in the dp cycle.

Abstract
Functionalization of textile fabrics with metal oxide nanoparticles can be used to add antibacterial and moisture management properties to them. Current work focuses on the development of these properties on polyester/cotton woven fabrics by treating them with zinc oxide nanoparticles for workwear and sportswear applications. Zinc oxide nanoparticles, prepared by sol-gel method, were applied on fabric samples, which were then tested for antibacterial and moisture management properties using standard test methods AATCC 147 with Staphylococcus aureus and AATCC 195, respectively. It was found that application of ZnO nanoparticles improved both these properties with smaller particle imparting larger effects on both of them.

Abstract
The aim of this paper is to address the surface reconstruction from point cloud in reverser engineering. The data was acquired through a 3D scan device and was processed as point cloud data. The points in cloud were connected to build 3D surface. The points cloud was processed in four steps to get 3D information surface. First, the subtraction scheme was used to get cover boxes ended with the set of convex was found under the convergence rule. Secondly, the points in the box were projected to the directions which were close to the normal direction method. Thirdly the overlap was avoided by using convergence rule and inner subdivision rule. Finally the information model was used to reconstruction. The method was used in landslide monitoring of Three Gorges area for 3D surface reconstruction and monitoring. The reconstruction method obtains high precision and low complexity. It is effective for large scale monitoring.

Abstract
Since the traditional computer vision ranging algorithm is imperfect in pertinence and precision, night time monocular vision pedestrian ranging method is proposed for vehicular infrared night vision goggles. Firstly, the method calibrated the internal and external parameters of infrared night-vision goggles, then, it corrected distortion of collected Vehicular Infrared Night Vision Image, and finally it ranged objective pedestrians by using night time monocular vision pedestrian ranging algorithm. The experimental results show that this method has the characteristics of pertinence, high precision and good real-time, and has good practicability.
A comparative study on learning strategies used by Australian CFL and Chinese EFL learners
Authors: Jiang Wenying , Wu Qingyu 
Published: October 2016

AbstractThis study compared language learning strategies used by Chinese as a foreign language (CFL) learners in Australia and English as a foreign language (EFL) learners in China through Oxford’s (1990. Language learning strategies: What every teacher should know. Boston: Heinle and Heinle.) Strategy Inventory of Language Learning (SILL) questionnaire survey. Two cohorts of learners, namely Australian CFL learners (N=101) and Chinese EFL learners (N=100), participated in this study. It was found that the most frequently used strategies by the Chinese EFL learners were compensation strategies and the least frequently used strategies were memory strategies while the most frequently used strategies by the Australian CFL learners were social strategies and the least frequently used strategies were affective strategies. Australian female learners used slightly more strategies than male learners, but no difference was found in the strategies used by the Chinese EFL male and female learners. No significant difference was found either in the strategies used by learners of different grade levels, regardless of whether they were Chinese EFL or Australian CFL learners. Scores of some individual categories significantly differed between the three levels of the Australian CFL learners and the four levels of the Chinese EFL learners. In general the Chinese EFL learners used more strategies when compared with those used by the Australian CFL learners. Pedagogical implications of the findings were also discussed. This study contributes to the research in language learning strategies in that it considers the typological distance between learners’ L1 and the target language for the first time. It also has clarified the seemingly inconsistent findings in the literature in terms of memory strategies use by Asian learners (Chinese learners in this case): when compared with other categories of strategies, memory strategies were used the least frequently by the Chinese EFL learners; when compared with learners from other cultural backgrounds such as the Australian or American, the Chinese EFL learners used memory strategies more frequently.

Authors: Kijowska-Strugała Małgorzata , Wiejaczka Łukasz , Kozłowski Rafał 
Published: October 2016

Abstract
The aim of the analysis was to demonstrate the role of reservoirs in shaping nutrient content (nitrates NO3
- and phosphates PO4
3- as well as ammonia NH4
+) in the waters of mountain rivers. Three Carpathian rivers with reservoirs in their courses were selected for the study: the Ropa River (Klimkowka reservoir), the Dunajec River (the Czorsztyn-Sromowce Wyzne reservoir complex) and the Raba River (Dobczyce reservoir). The basic criteria for the selection of the study objects for the investigation were: similar hydrological regime of the rivers and diverse parameters and functions of the storage reservoirs. The analysis of nutrient concentration was based on a long-term series of measurements (2004-2013). The reservoirs investigated generally contribute to an increase in nitrates in the rivers flowing below the reservoirs in particular months. The role of reservoirs in shaping phosphate and ammonia levels was not as evident as in the case of nitrates. The reservoirs are merely one of numerous factors that contribute to nutrient levels in the water of the mountains rivers. In the light of the analysis of nutrient concentrations in the surface water tested, it may be concluded that the reservoirs do not cause a clear and permanent deterioration of river water quality.

Published: October 2016

Abstract
Investigations concerning the effect of hemp oil on mortality of the foxglove aphid (Aulacorthum solani Kalt.) and the two spotted spider mite (Tetranychus urticae Koch) were conducted in the years 2014-2015. The tested essential oil was produced at the Institute of Natural Fibers and Medicinal Plants in Poznan. It was obtained by steam distillation of fresh panicles of Polish hemp cultivars, Beniko, Bialobrzeskie and Silesia, with low cannabinoid contents, including THC (max. 0.2% plant fresh matter). The effect of essential oil on the investigated pests was determined following the application of aqueous emulsion solution at 0.02, 0.05 and 0.1%. Mortality of agrophages was determined 24, 48 and 72 h after treatment. In this study a very high efficacy of the essential oil produced from hemp panicles was found in the reduction of population size of the foxglove aphid (A. solani). Already at 24 h after its application at a concentration of 0.1% pest mortality rate was 98.20%, while after 48 h it reached 100%. A significant, although much lesser effect of oil on the aphid population was recorded when applying it at 0.05%, with the mortality rate of the true bug after 72 h amounting to 57.33%. Essential oil also showed an effect on the two spotted spider mite (T. urticae). Following the oil application, irrespective of its concentration, a significant effect on mite mortality was observed. Its action was the strongest at its highest concentration, ie 0.1%, while mortality of the pest at 24, 48 and 72 h after treatment was 83.28, 95.83 and 98.72%, respectively.

A Method for The Assessing of Reliability Characteristics Relevant to an Assumed Position-Fixing Accuracy in Navigational Positioning Systems
Authors: Specht Cezary , Rudnicki Jacek 
Published: October 2016

Abstract
This paper presents a method which makes it possible to determine reliability characteristics of navigational positioning systems, relevant to an assumed value of permissible error in position fixing. The method allows to calculate: availability , reliability as well as operation continuity of position fixing system for an assumed, determined on the basis of formal requirements - both worldwide and national, position-fixing accuracy. The proposed mathematical model allows to satisfy, by any navigational positioning system, not only requirements as to position-fixing accuracy of a given navigational application (for air , sea or land traffic) but also the remaining characteristics associated with technical serviceability of a system.
Essence of the method in question consists in the working-out of recorded empirical position-fixing data as well as the making use of multi-state Markov processes ( appropriate to a maximum error value permissible for various navigational applications ) as a result of which reliability characteristics based on real data would be determined. About usefulness of a given navigational positioning system for its possible application would decide a vector of variables (both dealing with position and reliability) which satisfies / or does not satisfy / formal navigational requirements for a given application.
