This research is to know the development procedure of IPA game media for class IV MI / SD, to know the quality or feasibility of IPA game media for MI / SD students based on media expert and material expert, and to know the result of IPA game media development in increasing interest and learning result for fourth grade student MI Muhammadiyah Jalakan and SD Muhammadiyah Bogor in Gunungkidul. This type of research is Research and Development (R & D). Development procedures include potentials and problems, planning, drafting of products, design validation, design revisions, limited field trials, revisions of limited field trial results, broad field trials, and final product revisions. The results of the research are: 1) The game media in question is the game of Petir Pelangi and Monopoli IPA which is a game form in which there are IPA materials specially in Chapter Change of Earth Appearance and Celestial Material for class IV made by using Paint program, and equipped with auxiliary tools. 2) The results of validation of media experts and material experts indicate that the game of Petir Pelangi and Monopoli IPA is feasible or better used as media of learning media. This is based on the score score of Petir Pelangi game and Monopoli IPA respectively reaching an average of 4.3 in very good category, and 4.08 in good category. 3) In limited field trials and extensive field trials of rainbow lightning games and IPA monopolies can only increase consecutive learning interest by 6.55 with a standard gain of 0.41 in the medium category and 4, 64 with a standard gain of 0.27 in the low category. Whereas for the average of the students' learning outcomes on the limited field test and the wide field test of both game media can increase 12.77 with the standard gain of 0.31 in the medium category and 13.4 with the standard gain of 0.33 at medium category

Though data warehousing is widely recognized in the industry as the principal decision support system architecture and an integral part of the corporate information system, the majority of academic institutions in the US and world-wide have been slow in developing curriculums that reflect this. The authors examine the issues that have contributed to the lag in the coverage of data warehousing topics at universities and introduce methods, concepts and resources that can enable business educators to deal with these issues and conduct comprehensive, detailed, and meaningful coverage of data warehouse related topics.

Field engineering considerations for long-duration service and support involve not only the operation and maintenance of a system, but the abilities, import, and impact of the men who will conduct the operation and maintenance in the field. In the case of foreign assignment, habitability or diplomacy may be as much a problem as engineering. The role of the field engineer as a professional field support individual is discussed. Human factors is introduced in terms of practical examples experienced by Bendix Field Engineering during its 15 years of world-wide field support.

On The Road

A goal to reduce the frequency of animal–vehicle collisions is motivating extensive research on this topic world-wide. Over the last 30 years, one popular mechanism to warn wildlife of approaching vehicles has been the wildlife warning reflector, manufactured and distributed under the brands Swareflex (Austria) and Strieter-Lite (USA). These reflectors were designed to scare deer and other ungulates from roadways at night by reflecting light from the headlights of approaching vehicles into the eyes of animals on the road verge. Robust documentation of their effectiveness has been lacking, yet there has been a push in Australia to examine their efficacy with regard to medium to large macropodids. Field trials of the reflectors are problematic and difficult to design rigorously, so we chose to examine the behavioural response of two captive macropodid species (Macropus rufus and M. rufogriseus) to the reflectors on a simulated road in order to derive some indication as to their efficacy. The behavioural response to the reflectors was negligible for both species and not consistent with an aversive effect to deter road use or crossing. We conclude that they would be of little value in our efforts to reduce the frequency of collisions of kangaroos or wallabies with vehicles in Australia.

Abstract Plant roots change their morphological traits in order to adapt themselves to different environmental conditions, resulting in alteration of the root system architecture. To understand this mechanism, it is essential to visualize morphology of the entire root system. To reveal effects of long-term alteration of gravity environment on root system development, we have performed an experiment in the International Space Station using Arabidopsis plants and obtained dried root systems grown in rockwool slabs. X-ray computed tomography (CT) technique using industrial X-ray scanners has been introduced to visualize root system architecture of crop species grown in soil in 3D non-invasively. In the case of the present study, however, root system of Arabidopsis is composed of finer roots compared with typical crop plants and rockwool is also composed of fibers having similar dimension to that of the roots. A higher spatial resolution imaging method is required for distinguishing roots from rockwool. Therefore, in the present study, we tested refraction-contrast X-ray micro-CT using coherent X-ray optics available at the beamline of the synchrotron radiation facility SPring-8 for bio-imaging. We have found that wide field of view but with low resolution obtained at the experimental Hutch 3 of this beamline provided an overview map of the root systems, while narrow field of view but with high resolution obtained at the experimental Hutch 1 provided extended architecture of the secondary roots, by clear distinction between roots and individual rockwool fibers, resulting in successful tracing of these roots from their basal regions.

AbstractThis paper describes the system architecture of a newly constructed radio telescope – the Boolardy engineering test array, which is a prototype of the Australian square kilometre array pathfinder telescope. Phased array feed technology is used to form multiple simultaneous beams per antenna, providing astronomers with unprecedented survey speed. The test array described here is a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously, allowing several square degrees to be imaged in a single pointed observation. The main purpose of the test array is to develop beamforming and wide-field calibration methods for use with the full telescope, but it will also be capable of limited early science demonstrations.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.
