Nonlinear Physics Center was established in 2002, as a small group working on various problems of nonlinear dynamics and solitons. Then it became a separate department of the Research School of Physics and Engineering which was continuously expanding with the support from the Australian Research Council (ARC) through a variety of different funding schemes — individual fellowships and the ARC Center of Excellence program. In August 2014, the Center's research was conducted by 17 researchers and 19 PhD students (see Fig 1). Currently, the Nonlinear Physics Center is engaged in theoretical and experimental research in several areas unified by the general concepts of nonlinear physics and photonics. The Center is composed of several major research groups with not sharply defined boundaries.

This study attempts to discover the effect of applying Small Group Work Strategy on students’ achievement in writing procedure text. It was conducted by using experimental research design. The population of this research was the nineth (IX) grade students of SMP N 1 Padang Bolak Julu which consists of 3 parallel classes with the total number of students is 90. The samples of this research were taken by random sampling through lottery technique. The result was class IX1 consisted of 30 students became the experimental group and class IX3 consisted of 30 students became the control group. The experimental group was taught by Small Group Work Strategy while the control group was taught by using individual work strategy. The instrument was used to collect the data was writing procedure text. After the data were analyzed, it was found that the value of t-observed was 3.37 with the degree of freedom (df) = 58 at the level significance 0.05. it means that t-observed was higher than t-table (3.37 > 2.00. Therefore, the null hypothesis (Ho) is reected and the hypothesis alternative (Ha) is accepted.Key words : Small Group Work Strategy, Writing Procedure Text.

AbstractImproving the accuracy of absolute energies associated with rovibronic quantum states of molecules requires accurate high-resolution spectroscopy measurements. Such experiments yield transition wavenumbers from which the energies can be deduced via inversion procedures. To address the problem that not all transitions contribute equally to the goal of improving the accuracy of the energies, the method of Connecting Spectroscopic Components (CSC) is introduced. Using spectroscopic networks and tools of graph theory, CSC helps to find the most useful target transitions and target wavenumber regions for (re)measurement. The sets of transitions suggested by CSC should be investigated by experimental research groups in order to select those target lines which they can actually measure based on the apparatus available to them. The worked-out examples, utilizing extensive experimental spectroscopic data on the molecules H$$_2^{~16}$$ 2 16 O, $$^{32}$$ 32 S$$^{16}$$ 16 O$$_2$$ 2 , H$$_2^{~12}$$ 2 12 C$$^{16}$$ 16 O, and $$^{14}$$ 14 NH$$_{3}$$ 3 , clearly prove the overall usefulness of the CSC method and provide suggestions how CSC can be used for various tasks and under different practical circumstances.

Resource sharing has become an absolute necessity for modern scientific research because of the increasing expense and complexity of instruments, and the ever changing funding paradigm which often requires sharing of major instrumentation resource across multiple disciplines. Many universities and even large companies have set up centralized facilities to serve researchers from different departments, divisions and units to minimize expenses and maximizing usage.Just in the materials research area alone, it is estimated that there are more than 500 mid-size facilities existing nationwide, as reported in 2005 by the Committee on Smaller Facilities of National Research Council. Resource sharing is also common in large research groups, between Principal Investigators, as well as in corporate/industrial laboratories.
