    This dissertation revolves around the question of how local governments are making sense and are responding to the challenges of increasingly diverse societies. I thereby focus on the empirical reality of government workers and migrants. My research question is as follows: __How do local governing actors make sense of and respond to migration-related diversity and how can these responses be explained?_

    Application of Shallot Cultivation Technology in Enrekang, South Sulawesi. Shallot is one of the important vegetable crops in South Sulawesi, but the level of productivity is still low at 6 t / ha. This is caused partly by the lack of specific location technology. The purpose of the assessment is to to get a package of shallot cultivation technology appropriate and in accordance with local conditions. Assessments conducted at Tominawa Village, Baraka Sub-district, Enrekang District from March to December 2008, using a paired plot design, with two treatments: (1) The application of cultivation technology and (2) Cultivation of farmer ways. The assessment indicated that the application of cultivation technology as recommended giving shallot growth better than the way farmers plant growth. In this treatment of tuber fresh weight per 10 groves of shallots, tubers and higher tuber diameter of each 937 g, 3.86 cm and 4.20 cm. Furthermore, the number of tubers per hill and tuber dry weight per 10 clusters each tuber and 810 g. 7.28 While the yield obtained on the recommendation technology is 2772 kg/ha, equivalent 0.35 7.92 t/ha. Acceptance of farmers on the application of technology recommended treatment is USD. 30,492,000 as of 0.35 ha with RC ratio of 2.45

    Relaps level for the ex-user is high. This is the reason why si difficult to reduce the relapseffect. Beside medical and individual reason, family plays an important role to prevent therelaps. This research uses case study as research approach. Assessment is done by usinginterview and observation, and the use of Circumplex Assessment Package consist of FACESIII (Adaptability Cohesive Evaluatuion Scale and CRS or Circumplex Rating Scale). Theresult shows the enmaeshed-chaotic as family type A that shows some of the communicationskill problems in the family. After the result of the assessment, circumplex model familytherapy is arranged with some modification considering subject's family problems. Thetherapy arrangement is divided into 10 session with time schedule family confirmation

    Origin of the neutron skin thickness of 208Pb in nuclear mean-field models

    Get PDF
    We study whether the neutron skin thickness (NST) of 208Pb originates from the bulk or from the surface of the nucleon density distributions, according to the mean-field models of nuclear structure, and find that it depends on the stiffness of the nuclear symmetry energy. The bulk contribution to NST arises from an extended sharp radius of neutrons, whereas the surface contribution arises from different widths of the neutron and proton surfaces. Nuclear models where the symmetry energy is stiff, as typical relativistic models, predict a bulk contribution in NST of 208Pb about twice as large as the surface contribution. In contrast, models with a soft symmetry energy like common nonrelativistic models predict that NST of 208Pb is divided similarly into bulk and surface parts. Indeed, if the symmetry energy is supersoft, the surface contribution becomes dominant. We note that the linear correlation of NST of 208Pb with the density derivative of the nuclear symmetry energy arises from the bulk part of NST. We also note that most models predict a mixed-type (between halo and skin) neutron distribution for 208Pb. Although the halo-type limit is actually found in the models with a supersoft symmetry energy, the skin-type limit is not supported by any mean-field model. Finally, we compute parity-violating electron scattering in the conditions of the 208Pb parity radius experiment (PREX) and obtain a pocket formula for the parity-violating asymmetry in terms of the parameters that characterize the shape of the 208Pb nucleon densities.Comment: 11 pages, 4 figures; minor stylistic changes in text, new Ref.

    Gaharu (Aquilaria malaccensis L) is one of the non timber forest products (HHBK) has high-value commercial. The high value caused the demand for commodities is increasing every year. But it is inversely proportional to its availability in nature. This research aims to determine the best concentration of the addition of NAA, BAP and the combination between the NAA and BAP on growth of root and shoot of gaharu. The benefits of this research are expected to be a reference in the provision of seedlings with vegetative reproduction in agarwood technique of tissue culture, to support the procurement activities of the seeds in a sufficient amount of a good quality in a relatively short time, and the resulting seedlings were uniform. The methods used factorial experimental design of Randomized complete (RAL) consisting of two factors and three times in Deuteronomy. NAA factor consists of five degrees of treatment i.e. N0 = 0 mg/l, N1 = 1 mg/l, N2 = 2 mg/l, N3 = 3 mg/l and N4 = 4 mg/l, whereas the factor of BAP is also composed of five degrees of concentration i.e. B0 = 0 mg/l, B1 = 0.5 mg/l, B2 = 1 mg/l, B3 = 1.5 mg/l and B4 = 2 mg/l with three times the replay so that required 75 eksplan gaharu. The results showed the best NAA concentration in the added of shoots with a concentration of 0 mg/l NAA, while concentration of 3 mg/l NAA was the best concentration of length the shoots and growth added root gaharu. The best concentration of BAP on shoot length and added long shoots are concentration of 0,5 mg/l BAP, while concentration of 0 mg/l BAP is the best concentration of the growth roots gaharu. Key words : Naphthalene acetic acid, benzyl amino purine, growth hormone, subcultures and aquilaria malaccensis

    Fission modes of mercury isotopes

    Background: Recent experiments on beta-delayed fission in the mercury-lead region and the discovery of asym- metric fission in 180 Hg [1] have stimulated theoretical interest in the mechanism of fission in heavy nuclei. Purpose: We study fission modes and fusion valleys in 180 Hg and 198 Hg to reveal the role of shell effects in pre-scission region and explain the experimentally observed fragment mass asymmetry and its variation with A. Methods: We use the self-consistent nuclear density functional theory employing Skyrme and Gogny energy density functionals. Results: The potential energy surfaces in multi-dimensional space of collective coordinates, including elongation, triaxiality, reflection-asymmetry, and necking, are calculated for 180 Hg and 198 Hg. The asymmetric fission valleys - well separated from fusion valleys associated with nearly spherical fragments - are found in in both cases. The density distributions at scission configurations are studied and related to the experimentally observed mass splits. Conclusions: The energy density functionals SkM\ast and D1S give a very consistent description of the fission process in 180 Hg and 198 Hg. We predict a transition from asymmetric fission in 180 Hg towards more symmetric distribution of fission fragments in 198 Hg. For 180 Hg, both models yield 100 Ru/80 Kr as the most probable split. For 198 Hg, the most likely split is 108 Ru/90 Kr in HFB-D1S and 110 Ru/88 Kr in HFB-SkM\ast.Comment: 6 pages, 5 figures, to be published in Physical Review
