    Kecantikan adalah identitas. Kecantikan merupakan sesuatu yang membuat wanita berbeda dari laki-laki. Kecantikan merupakan citra dari seorang wanita. Robert Jones (2011) mengungkapkan bahwa kebanyakan orang terobsesi dengan kecantikan dari luar (outward beauty), sampai-sampai mereka melupakan kecantikan dari dalam (inner beauty). Akan tetapi, sangat memungkinkan bahwa kecantikan dari luar merupakan cerminan hasrat seseorang untuk mengekspresikan kecantikan dari dalam diri-nya. Menurutnya, elemen paling penting dari kecantikan yang sesungguhnya adalah kepercayaan diri. Kepercayaan diri sendiri dapat ditimbulkan salah satunya dengan menonjolkan penampilan luar. Menurut Bobbi Brown (2011) wanita akan memperoleh kepercayaan diri yang lebih apabila mengerti tentang makeup, dengan memilih alat yang tepat, menemukan warna yang cocok untuknya dan menguasai teknik dasar dalam mengaplikasikannya. Artikel ini didasarkan pada Karya Tugas Akhir berjudul “Perancangan CD Interaktif ‘What Makes You Beautiful' Ensiklopedia Kosmetik Interaktif bagi Pemula” yang ditujukan untuk menjawab kebingungan/permasalahan wanita tentang bagaimana cara memilih kosmetik yang tepat untuk mempercantik dirinya dari luar ditengah maraknya peredaran berbagai jenis kosmetik di pasaran

    Well-balanced treatment of gravity in astrophysical fluid dynamics simulations at low Mach numbers

    Accurate simulations of flows in stellar interiors are crucial to improving our understanding of stellar structure and evolution. Because the typically slow flows are merely tiny perturbations on top of a close balance between gravity and the pressure gradient, such simulations place heavy demands on numerical hydrodynamics schemes. We demonstrate how discretization errors on grids of reasonable size can lead to spurious flows orders of magnitude faster than the physical flow. Well-balanced numerical schemes can deal with this problem. Three such schemes were applied in the implicit, finite-volume Seven-League Hydro (SLH) code in combination with a low-Mach-number numerical flux function. We compare how the schemes perform in four numerical experiments addressing some of the challenges imposed by typical problems in stellar hydrodynamics. We find that the α\alpha-β\beta and deviation well-balancing methods can accurately maintain hydrostatic solutions provided that gravitational potential energy is included in the total energy balance. They accurately conserve minuscule entropy fluctuations advected in an isentropic stratification, which enables the methods to reproduce the expected scaling of convective flow speed with the heating rate. The deviation method also substantially increases accuracy of maintaining stationary orbital motions in a Keplerian disk on long timescales. The Cargo-LeRoux method fares substantially worse in our tests, although its simplicity may still offer some merits in certain situations. Overall, we find the well-balanced treatment of gravity in combination with low Mach number flux functions essential to reproducing correct physical solutions to challenging stellar slow-flow problems on affordable collocated grids.Comment: Accepted for publication in A&

    Purpose: Degraded soils, such as those encountered in areas of mine activities, need to be ameliorated by liming to correct soil acidity and by addition of organic inputs to improve soil properties and fertility. Materials and methods: Non-amended mine soil and soil amended with stabilized sewage sludge were incubated for 45 days. Soil physicochemical and biological indicators were periodically measured along incubation and other enzyme activities at the end of incubation. In improved soils, a study of plant development in 250-g pots was carried out with three vegetal species: tomato, rye grass and ahipa. Germination and mortality rates, biomass production and photosynthetic pigments were measured. Results and discussion: Soil incubation with sewage sludge slightly increased soil pH and led to an enhancement of soil electrical conductivity, organic carbon and dehydrogenase activity, especially for the higher doses (5 and 10%). However soil respiration was more promoted with the 2% dose, pointing to a possible toxic effect of the sludge. At the end of incubation, physicochemical and biological properties were in general enhanced. Biomass production was improved in tomato and rye grass by sewage sludge addition (more at the 2% dose), whilst ahipa growth was not affected by sewage sludge treatments. Tomato mortality reached 73% with high sludge doses (10%). Conclusions: According to this set of parameters, amendment with sewage sludge of a limed acid mine soil would be considered as a good strategy for soil amelioration in view of plant establishment and development.Junta de Andalucía P10-RNM581

    Dynamics in a stellar convective layer and at its boundary: Comparison of five 3D hydrodynamics codes

    This is the final version. Available from EDP Sciences via the DOI in this recordOur ability to predict the structure and evolution of stars is in part limited by complex, 3D hydrodynamic processes such as convective boundary mixing. Hydrodynamic simulations help us understand the dynamics of stellar convection and convective boundaries. However, the codes used to compute such simulations are usually tested on extremely simple problems and the reliability and reproducibility of their predictions for turbulent flows is unclear. We define a test problem involving turbulent convection in a plane-parallel box, which leads to mass entrainment from, and internal-wave generation in, a stably stratified layer. We compare the outputs from the codes FLASH, MUSIC, PPMSTAR, PROMPI, and SLH, which have been widely employed to study hydrodynamic problems in stellar interiors. The convection is dominated by the largest scales that fit into the simulation box. All time-averaged profiles of velocity components, fluctuation amplitudes, and fluxes of enthalpy and kinetic energy are within ≲3σ of the mean of all simulations on a given grid (1283 and 2563 grid cells), where σ describes the statistical variation due to the flow’s time dependence. They also agree well with a 5123 reference run. The 1283 and 2563 simulations agree within 9% and 4%, respectively, on the total mass entrained into the convective layer. The entrainment rate appears to be set by the amount of energy that can be converted to work in our setup and details of the small-scale flows in the boundary layer seem to be largely irrelevant. Our results lend credence to hydrodynamic simulations of flows in stellar interiors. We provide in electronic form all outputs of our simulations as well as all information needed to reproduce or extend our study.Science and Technology Facilities Council (STFC)European Research Council (ERC
