Respon Rusa Timor Terhadap Pemberian Pakan Alternatif Di Penangkaran

The aim of the research are to analyzed the silage quality, analyze feeding behaviour of timor deer in introduction of silage, to evaluation the effect of alternative feed that is elephant grass, elephant grass silage and waste farm silage (rice straw and banana trunk) to performance of timor deer, from palatability, average daily consumption, average daily gain and feed conversion. Experimental design used completely randomized design with three treatments and three repetition. The treatments were P1: 72% elephant grass and 28% elephant grass silage, P2: 65% elephant grass and 35% rice straw silage, P3: 54% elephant grass and 46% banana trunk silage. Addition 3% molases result good quality silage of elephant grass silage, rice straw silage and banana culm silage in term of physical and chemical characteristics. Timor deer in the captive gave a positive response to eating behaviour and adaptive to the silage as an alternative feed. Analysis of palatability with Manly's Alpha showed there was trend elephant grass silage and banana trunk silage have good palatability than rice straw silage. Analysis of Variance showed that the experiment feed (P1, P2 and P3) were not significantly different effect (p>0.05) to average daily consumption, average daily gain, and feed conversion, but the best feed conversion obtained from P3, so P3 (RGS+SBP) is considered more efficient and profitable than P1 (RGS+SRG) and P2 (RGS+SJP) in biological and economic technically and can be chosen as an alternative feed to Timor deer in the captive

In addition the adequacy of manpower is already implementing a policy that is goodwith officers and employees of the PD marketManado city that exists in the market Bersehati. Similarly, thedecisions taken in case of problems or constraints in implementation is always good for the commongoodparty PD. Manado City Market or user community market. However for the benefit of employees andresponse against complaint merchants still showed a less good results. Similarly, the strategies used are alljust communication and sosialisai without any action even though the degree of change that's been good tobe achieved, namely repair and upgrading of infrastructure and quality of service. So consequently thetraders became feel aggrieved

Creating mock catalogues of stellar haloes from cosmological simulations

We present a new technique for creating mock catalogues of the individual stars that make up the accreted component of stellar haloes in cosmological simulations and show how the catalogues can be used to test and interpret observational data. The catalogues are constructed from a combination of methods. A semi-analytic galaxy formation model is used to calculate the star formation history in haloes in an N-body simulation and dark matter particles are tagged with this stellar mass. The tags are converted into individual stars using a stellar population synthesis model to obtain the number density and evolutionary stage of the stars, together with a phase-space sampling method that distributes the stars while ensuring that the phase-space structure of the original N-body simulation is maintained. A set of catalogues based on the Λ cold dark matter Aquarius simulations of Milky Way mass haloes have been created and made publicly available on a website. Two example applications are discussed that demonstrate the power and flexibility of the mock catalogues. We show how the rich stellar substructure that survives in the stellar halo precludes a simple measurement of its density profile and demonstrate explicitly how pencil-beam surveys can return almost any value for the slope of the profile. We also show that localized variations in the abundance of particular types of stars, a signature of differences in the composition of stellar populations, allow streams to be easily identified

The Copernicus Complexio: Statistical Properties of Warm Dark Matter Haloes

The recent detection of a 3.5 keV X-ray line from the centres of galaxies and clusters by Bulbul et al. and Boyarsky et al. has been interpreted as emission from the decay of 7 keV sterile neutrinos which could make up the (warm) dark matter (WDM). As part of the Copernicus Complexio (COCO) programme, we investigate the properties of dark matter haloes formed in a high-resolution cosmological N-body simulation from initial conditions similar to those expected in a universe in which the dark matter consists of 7 keV sterile neutrinos. This simulation and its cold dark matter (CDM) counterpart have ∼13.4 bn particles, each of mass ∼105 h−1 M⊙, providing detailed information about halo structure and evolution down to dwarf galaxy mass scales. Non-linear structure formation on small scales (M200 ≲ 2 × 109 h−1 M⊙) begins slightly later in COCO-WARM than in COCO-COLD. The halo mass function at the present day in the WDM model begins to drop below its CDM counterpart at a mass ∼2 × 109 h−1 M⊙ and declines very rapidly towards lower masses so that there are five times fewer haloes of mass M200 = 108 h−1 M⊙ in COCO-WARM than in COCO-COLD. Halo concentrations on dwarf galaxy scales are correspondingly smaller in COCO-WARM, and we provide a simple functional form that describes its evolution with redshift. The shapes of haloes are similar in the two cases, but the smallest haloes in COCO-WARM rotate slightly more slowly than their CDM counterparts

Good covers are algorithmically unrecognizable

A good cover in R^d is a collection of open contractible sets in R^d such that the intersection of any subcollection is either contractible or empty. Motivated by an analogy with convex sets, intersection patterns of good covers were studied intensively. Our main result is that intersection patterns of good covers are algorithmically unrecognizable. More precisely, the intersection pattern of a good cover can be stored in a simplicial complex called nerve which records which subfamilies of the good cover intersect. A simplicial complex is topologically d-representable if it is isomorphic to the nerve of a good cover in R^d. We prove that it is algorithmically undecidable whether a given simplicial complex is topologically d-representable for any fixed d \geq 5. The result remains also valid if we replace good covers with acyclic covers or with covers by open d-balls. As an auxiliary result we prove that if a simplicial complex is PL embeddable into R^d, then it is topologically d-representable. We also supply this result with showing that if a "sufficiently fine" subdivision of a k-dimensional complex is d-representable and k \leq (2d-3)/3, then the complex is PL embeddable into R^d.Comment: 22 pages, 5 figures; result extended also to acyclic covers in version

Cosmic cookery : making a stereoscopic 3D animated movie.

This paper describes our experience making a short stereoscopic movie visualizing the development of structure in the universe during the 13.7 billion years from the Big Bang to the present day. Aimed at a general audience for the Royal Society's 2005 Summer Science Exhibition, the movie illustrates how the latest cosmological theories based on dark matter and dark energy are capable of producing structures as complex as spiral galaxies and allows the viewer to directly compare observations from the real universe with theoretical results. 3D is an inherent feature of the cosmology data sets and stereoscopic visualization provides a natural way to present the images to the viewer, in addition to allowing researchers to visualize these vast, complex data sets. The presentation of the movie used passive, linearly polarized projection onto a 2m wide screen but it was also required to playback on a Sharp RD3D display and in anaglyph projection at venues without dedicated stereoscopic display equipment. Additionally lenticular prints were made from key images in the movie. We discuss the following technical challenges during the stereoscopic production process; 1) Controlling the depth presentation, 2) Editing the stereoscopic sequences, 3) Generating compressed movies in display speci¯c formats. We conclude that the generation of high quality stereoscopic movie content using desktop tools and equipment is feasible. This does require careful quality control and manual intervention but we believe these overheads are worthwhile when presenting inherently 3D data as the result is signi¯cantly increased impact and better understanding of complex 3D scenes

Analogues of the central point theorem for families with dd-intersection property in Rd\mathbb R^d
