Assessment has various types in education program. Even, it was as one of aspect in determining the students’ skill. Additionally, one skill which is as the last skill in language acquisition is writing. Since it is the last, means it is difficult to be learnt moreover to be assessed. When writing is difficult to be assessed, the teacher has to know and understand various type of assessment for writing. This study was conducted to describe types of alternative assessment for writing skill in 2nd semester of Industrial Engineering at University of Muhammadiyah Gresik in academic year of 2016/2017 and also to describe implementation of Alternative Assessment for writing skill in second semester of Industrial Engineering at University of Muhammadiyah Gresik which used descriptive qualitative. There were two lecturers of D1 English Language at UMG who were as the subject of this study which were selected by questioners about the alternative assessment for writing skill. The data collected by observation in K and L classes of Industrial Engineering Department. Additionally, the interview was done with two lecturers and some students. The finding of this study showed that two lecturers applied alternative assessment with same type. Those were writing sample, conference, and teacher- feedback. Furthermore, the implementation of alternative assessment in writing skill was done by asking and drill the students in composing writing to make them comprehend about writing composition and be more confident for composing writing. After they comprehended then they could compose full text. When the students practice in writing, the lecturer guided them by discussing face to face or in whole class. The feedback had to be given to develop the students’ motivation in writing. When the motivation was high then the students could improve their writing composition and help the students to revise their writing’ work. It can be concluded that alternative assessment for writing skill which have been applied are writing sample, conference, and teacher-feedback. The writing sample uses as the practice by composing sentence then compose text to know the progress. The conference can be held in face to face with lecturer and with whole class. Additionally, the feedback can be given during activity and after activity in spoken and written by directly or indirectly. The researcher suggests the further researcher to conduct at another level. The researcher hopes that there will be further research on the implementation of alternative assessment for writing skill in different field or study with different subject and different focus.

Stefan Goldmann stellt Freuds formvollendete Krankengeschichten und die Traumdeutung in gattungs- und wissenschaftsgeschichtliche Traditionslinien des 19. Jahrhunderts. Hermeneutisch erschließt er eine Fülle unbekannter literarischer und fachwissenschaftlicher Quellen, mit denen sich Freud bei der Niederschrift der frühen Krankengeschichten und der Entwicklung seiner Traumtheorie methodisch auseinandersetzte.

Der Autor vergleicht die aus literaturwissenschaftlicher Sicht kaum behandelte Gattungsgeschichte der Krankengeschichte mit der Gattungstheorie der Novelle. Er benennt erstmals jene Novellen, an die Freud bei der Niederschrift der Krankengeschichten von »Elisabeth v. R.« und »Dora« dachte. Die Behandlungsgeschichte des »Kleinen Hans« fügt sich hingegen in eine Tradition, die bis in die Epoche der magnetischen Behandlung von Kindern und Jugendlichen um 1800 zurückreicht. Die Aufarbeitung der Geschichte der Traumforschung im 19. Jahrhundert fördert die Vorbilder für Freuds Traumdeutung zutage und lenkt die Aufmerksamkeit auf das von Dichtung und Wissenschaft erarbeitete umfangreiche Traumvokabular, das Freud aufgriff, um es systematisch neu auszuprägen. Die aufgezeigte Kontextabhängigkeit der hier untersuchten Werke vertieft unsere Kenntnis von Freud als klassischem Schriftsteller und topisch argumentierendem Denker.

Published: May 2019

The efficiency of breeding and production processes in dairy cattle breeding are closely linked and limited by the genetic value of animals, their reproduction ratio, and the rate of change of generations. The use transplantation of embryo in the practice of dairy cattle breeding ensures the effective implementation of modern reproductive biotechnology, which will promote the expanded reproduction of the most valuable, tested animal complexes.

Goal. To study the dynamics of live weight of calves-embryo-transplants and compare them with analogues obtained after artificial insemination, in conditions of farms of different climatic regions of Ukraine.

Methods. Zotechnical, statistical, analytical. Analytical part of the work was carried out on the retrospective data of zootechnical records in three farms, in the warehouse of which were introduced repair heifers-embryotransplantants. Biotechnological procedures (in vivo) for embryocollection, transplantation of fresh and frozen-thawed embryos were carried out in accordance with well-known techniques. Materials for system analysis were collected during the period of practical activity of the Laboratory of embryo transplantation at PJSC "Poltavapleservis" and in the period after its reorganization. To study the dynamics of the live weight of repair calves-embryo-transplants in three different climatic and technological conditions farms were selected analogue groups of calves of the corresponding age and breed (in the ALLC "Petrodolynske", the comparison was made with Ukrainian red dairy breeds) born after fertilization artificial insemination of heifers.

Results. It was established that the live weight of newborn calves-embryo-transplants of dairy breeds was lower compared to analogues by 6.8% (with fluctuations of 0.86–5.46 kg). Heifers-embryo-transplants yielded to live weight analogues for the entire period of the survey, but had a higher rate of growth. At 9 months of age, the difference in live weight was 4.7%, but the difference in farms of different climatic regions increased significantly: from 0.96 to 8.72%.

Conclusions. The tendency of the dependence of the dynamics of the live weight of heifers on the methods of reproduction biotechnology, as well as on the effects of the conditions of retention, is established. Some elements of this trend require further study, in order to optimize the technology of growing a repair stock with high genetic potential.

Influencia del régimen de caudales en los movimientos reproductivos de la trucha común en la Península Ibérica
Authors: García Vega Ana , Sanz Ronda Francisco Javier , Fuentes Pérez Juan Francisco , Bravo Córdoba Francisco Javier , Leunda Urretabizkaia Pedro Manuel
Published: May 2019

La trucha común (Salmo trutta) es una especie ampliamente distribuida a lo largo del mundo y de gran importancia social y económica. En general, el descenso de la temperatura del agua y el aumento de caudal estimulan su migración reproductiva. Por lo tanto, alteraciones antropogénicas de estos factores pueden causar impactos negativos en sus poblaciones. El objetivo de este trabajo es entender las consecuencias de alteraciones artificiales en el régimen de caudales sobre la migración de la trucha común. Para ello, se comparan las capturas de trucha en escalas para peces (puntos obligatorios de paso para la migración) en dos ríos de la Península Ibérica sometidos a diferentes regímenes hidrológicos (atlántico y mediterráneo) y bajo diferentes escenarios de regulación de caudales. Los resultados de este trabajo muestran que el aumento del caudal estimula los movimientos e influye significativamente en el inicio y mantenimiento de la migración reproductora. Además, los diferentes regímenes de caudales provocan diferencias en las fechas medias de migración. Conocer los factores que influyen en la migración de la trucha común será muy útil para definir estrategias para su conservación y manejo (e.g. definición de caudales ecológicos, funcionamiento de pasos para peces, períodos y cupos de pesca, etc.).

Entre los servicios ecosistémicos prestados al hombre se encuentran el agua potable, los alimentos, la biomasa, la calidad del aire y la regulación climática. En las tierras secas del planeta, los habitantes ejercen una fuerte presión en los ecosistemas, para la producción de alimentos y biomasa. Este trabajo plantea cómo los servicios ambientales son alterados por el manejo de la vegetación en un bosque tropical seco. La investigación se desarrolla en dos microcuencas (<2 ha), de pendiente suave (10,5 y 9%), mismo suelo, misma clase textural, con cursos efímeros de 1º/2º orden, del semiárido brasileño, durante el período 2008-2017. En el año 2008, las dos microcuencas presentaban el mismo tipo de vegetación, una formación arbustivo-arbórea, denominada Caatinga, para cuantificar la escorrentía antes de la transformación de la cobertura vegetal. Una microcuenca mantuvo la vegetación nativa inalterada, siendo la otra aclarada un 40%. Se monitorizaron la escorrentía superficial, la humedad edáfica, el transporte de sedimentos, la biomasa herbácea y radicular. En 2008, las dos microcuencas presentaron una escorrentía superficial similar (85 mm). A partir de 2009, en la microcuenca aclarada aumentaron la biomasa herbácea y radicular, lo que redujo la escorrentía superficial y la pérdida de suelo, mientras se incrementó la humedad edáfica. Se observa que el manejo de la vegetación, con una visión ecohidrológica, altera el funcionamiento hidrológico, que afecta a la producción de los servicios ecosistémicos.

El mercado oferta numerosos sistemas de riego con el objetivo de conseguir el establecimiento de la plantación y de evitar la reposición de plantas muertas por estrés hídrico. El presente trabajo determina la eficiencia técnica global y pura de los sistemas de riego más utilizados mediante el método no paramétrico de análisis envolvente de datos (DEA). El método DEA se aplica tanto a los sistemas individuales de riego como al principio hidráulico de entrega de agua. La variable de entrada es el coste unitario de instalación y la variable de salida la eficiencia de aplicación de agua. Los datos de entrada se obtienen por revisión bibliográfica. Los resultados indican que existen diferencias en las eficiencias técnicas de los sistemas de riego disponibles en el mercado, señalando que los sistemas de riego convencionales presentan ineficiencias técnicas y que están operando fuera de la escala del sector. La eficiencia técnica de los sistemas de riego es una información valiosa para orientar a los industriales e inventores en el diseño y fabricación de sus sistemas, y para los proyectistas, a los que proporciona un criterio para elegir la tecnología de riego más eficiente técnicamente en el establecimiento de masas arboladas y/o arbustivas.

On charge percolation in slurry electrodes used in Vanadium Redox Flow Batteries
Authors: Wessling Matthias
Published: May 2019

In vanadium redox flow battery systems porous carbon felts are commonly employed as electrodes inside the flow channel. Recently, slurry electrodes (or flow suspension electrodes) were introduced as a potentially viable electrode system. Such electrode systems are little understood so far. Mass, momentum and charge transfer phenomena co-occur, interactions with each other are nearly impossible to capture experimentally. We present a novel discrete model of the particulate phase combining theories from fluid dynamics, colloidal physics, and electrochemistry with a coupled CFD-DEM approach. The methodology allows to visualize local phenomena occurring during the charging of the battery and to compute the net current of the slurry electrode system. We demonstrate that an increasing particle volume fraction enables the formation of conducting networks in the flow electrode until a threshold is reached. Our study concludes, that the assumption of all particles participating in the charge transfer as assumed in pure CFD investigations is not necessarily valid.

Authors: Wessling Matthias
Published: May 2019

Due to the complex interplay between surface adsorption and hydrodynamic interactions, representative microsocpic mechanisms of colloidal membrane fouling are still not well understood. Numerical simulations overcome experimental limitations such as the temporal and spatial resolution of microscopic events during colloidal membrane fouling: they help to gain deeper insight into fouling processes. This study uses coupled computational fluid dynamics - discrete element methods (CFD-DEM) simulations to examine mechanisms of colloidal fouling in a microfluidic architecture mimicking a porous microfiltration membrane. We pay special attention to how particles can overcome energy barriers leading to adsorption and desorption with each other and with the external and internal membrane surface. Interparticle interaction leads to a transition from the secondary to the primary minimum of the DLVO potential. Adsorbed particles can show re-entrainment or they can glide downstream. Since particles mainly resuspend as clusters, the inner pore geometry significantly affects the fouling behavior. The findings allow a basic understanding of microscopic fouling events during colloidal filtration. The methodology enables future systematic studies on the interplay of hydrodynamic conditions and surface energy contributions represented by potentials for soft and patchy colloids.

Published: May 2019

Tourism in Bali is dominated by cultural tourism inspired by the religiosity of Hinduism. The potential of Balinese religion and culture gives birth to many cultural products that become excellent tourist destinations. In this case, Kamasan Village, located in Klungkung Subdistrict, Klungkung Regency, has one of the mainstay products in the form of pis bolong (Uang Kepeng). The perforated industry in the village of Kamasan in this case is not only a tourist attraction, but also as a medium to socialize the religiosity of Balinese culture for tourists. In this case, tourists not only enjoy the destination, but also learn about religious and magical Balinese culture. This is very important to be studied in the midst of the massive phenomena of the degradation of the Balinese people's understanding of cultural religiosity, one of which is caused by the widespread circulation of imitation pis which is not in accordance with the religious principles of Balinese culture.
Culture influences how people divide continuous sensory experience into events.
Authors: Swallow Khena M. , Wang Qi
Published: May 2019

Everyday experience is divided into meaningful events as a part of human perception. Current accounts of this process, known as event segmentation, focus on how characteristics of the experience (e.g., situation changes) influence segmentation. However, characteristics of the viewers themselves have been largely neglected. We test whether one such viewer characteristic, their cultural background, impacts online event segmentation. Culture could impact event segmentation (1) by emphasizing different aspects of experiences as being important for comprehension, memory, and communication, and (2) by providing different exemplars of how everyday activities are performed, which objects are likely to be used, and how scenes are laid out. Indian and US viewers (N=152) identified events in everyday activities (e.g., making coffee) recorded in Indian and US settings. Consistent with their cultural preference for analytical processing, US viewers segmented the activities into more events than did Indian viewers. Furthermore, event boundaries identified by US viewers were more strongly associated with visual changes, whereas boundaries identified by Indian viewers were more strongly associated with goal changes. There was no evidence that familiarity with an activity impacted segmentation. Thus, culture impacts event perception by altering the types of information people prioritize when dividing experience into meaningful events.

Published: May 2019

Lahor Reservoir was built and functioned as a water provider for agricultural activities, flood control, electricity generation, tourism activities and inland fisheries. This reservoir is one of the inflows of the Sutami reservoir which is the largest reservoir in East Java. This Lahor Reservoir is drained by three rivers, namely the Lahor River, Leso River and the Dewi River, which flows through housing and paddy fields, allowing the entry of organic and inorganic materials from various activities around the rivers and reservoirs. The aim of the study was to assess the physico-chemical parameters of the Lahor reservoir during the dry season. This research was conducted between March and April 2018. Water quality analysis was carried out in the Laboratory of Environmental Engineering Department of ITN Malang. The study was conducted by survey method and sampling method. Measurement of physical and chemical parameters of the waters was determined at 4 stations and each station consisted of 5 sampling points with different depths. Data analysis using descriptive statistics (mean, graph). The assessment of the temperature in the waters of the Lahor Dam ranged from a value of 24-28o C, turbidity with a value of 0.4 NTU, DO values from surface to base increased significantly with values of 29.1 mg / L, 33.9 mg / L and 34.3 mg / L and still meet the minimum water requirements for aquaculture. The high BOD value at the Lahor reservoir outlet is influenced by the accumulation of organic substances from several inlets and dam waters. Phosphate values are higher along with water depth and Fecal Coli ranges from 1-2 MPN / 100 mL at all sampling points. In general, the Lahor reservoir water still meets the quality standards for class I waters.

Investigation of Fin Spacing for Heat Transfer Enhancement in Cross Flow Over Tubes Between Two Parallel Plates
Authors: Oumer Ahmad Nurye , Alias Amer Farhan
Published: May 2019

This research explains the investigation of fin spacing for heat transfer enhancement in the finned tube heat exchanger. The objective of this paper is to recommend the optimum fin spacing for heat transfer enhancement. Three different types of tube and spacing are identified through the simulation from Ansys software. The data between simulation using Ansys Fluent and published literature were being compared. Graph of total pressure, Nusselt number and total temperature have been plotted to make the comparison. Result obtained showed that were a bigger agreement between the simulation and published literature for both types of the tube which are circular and elliptic. From the analysis, there were considered two types of arrangement for the different types of tube. From that, the aligned arrangement is the best for heat transfer enhancement compared to the staggered. For the effect of spacing, there was three spacing which is 1.7 mm, 1.8 mm, and 2.0 mm spacing with velocity and the total heat flux is set to be constant (v =1.4 m/s; q = 500 W/m2). For the circular tube, it can be seen that the wider of the fin spacing gave the best heat transfer enhancement in the heat exchanger. Different from the circular which is 1.8 mm spacing is the best for heat transfer enhancement. Other types of tube are a flat surface which is comparing with the variations of Nu vs Re with different heat flux. Then, the result showed that as the Re is increased the Nu will also increase. In the other side, it is recommended for future work to do the real model dimension followed to import to the Ansys instead of assuming the model is symmetrical.

Published: May 2019

This research presents the application of Acoustic Emission (AE) sensor to explore the feasibility of an AE signal in the process of monitoring the engine oil viscosity on different condition of mileage during the engine operation. The viscosity experiment was performed in a prior stage of the experiment using four samples of SAE 5W-30 engine oil with the different condition of mileage. On the next occasion, the AE signal was acquired on three cylinders of a four-stroke gasoline engine with a cooling water system which operates using the previous lubricant sample. In this experiment, the AE sensor was bonded on the outside of the engine block and located at the oil filter and oil sump location. It was found that the AE energy value is capable of determining the variant of the engine oil viscosity. The results from this project show that via AE technology proved to be feasible for the development of a real-time lubricant condition monitoring which was believed to be a new technology in the automotive industry.
Spot Speed versus Speed Limit on Malaysian East-Coast Expressway
Authors: Arintono Sulistyo
Published: May 2019

Speed is one of the important causal factors for accidents on the road. This study aims to investigate the effectiveness of the speed warning sign on Malaysia’s East Coast Expressway where the rate of accident is high. Two points were selected, one representing locations far from any speed related warning sign, and one location immediately after a speed warning sign is in sight, to assess significance of the differences of the spot speeds. Results of the analysis suggest that the majority of vehicles (63.24%) travel over the speed limit, and that the speed warning sign does function in reducing the mean spot speed. However, the speed reduction is not to the desired level, i.e. under the speed limit. Other strategies have to be introduced to achieve the target.
Failure of a Truck Mounted Hydraulic Crane
Authors: Kaplan Mitchell P.
Published: May 2019

A truck-mounted hydraulic crane had a horizontal thrust bearing with one race attached to the truck and the other to the rotating crane. The outside race of the bearing was driven by a pinion gear, and it is through this mechanism that the crane body rotated about a vertical axis. The manufacturer welded the inner race to the carrier in a single pass. After several years of service, the attachment weld between the bearing inner race and the turntable failed in the area adjacent to the heat-affected zone. The fracture zone where there was the greatest tension was heavily oxidized. In the zone where the bearing was in compression, there was a clean surface indicating recent fracture. Finally, there were areas where the weld did not meet AWS specifications for convexity or concavity. These areas were weak enough to allow fatigue cracks to initiate. Recommendations to prevent reoccurrence of the failure include the use of bolts in lieu of welding, a welding schedule that reduces the propensity of lamellar tearing, and the use of an alloy that precludes lamellar tearing. However, if abuse of the crane was the primary cause of failure, none of these recommendations would have prevented deterioration of the machine to an extent that would have rendered the failure improbable.
