Faktor – Faktor Yang Menyebabkan Cost Overrun Pada Proyek Konstruksi

Pada Pekerjaan proyek konstruksi biasanya terjadi kendala, baik kendala yang sudah diperhitungkan maupun yang belum diperhitungkan. Sehingga proyek yang dikerjakan biasanya terlaksana dengan hasil yang tidak sesuai yang direncanakan. Oleh sebab itu penelitian ini sebagai upaya untuk mendapatkan dan mengetahui faktor-faktor apa saja yang mengakibatkan terjadinya cost overrun yang berpengaruh terhadap peningkatan kinerja biaya akhir proyek. Penelitian ini dilakukan dengan cara penyebaran kuesioner dan responden pada pembangunan gedung markas komando daerah militer Manado Sulawesi Utara, yang berlokasi di kota Manado pengolahan data kuesioner ini menggunakan program SPSS. Dari hasil penelitian didapatkan urutan rangking-rangking tiap faktor yang menjadi penyebab pembengkakan biaya pada penyelesaian proyek. Dengan menggunakan analisa Faktor- faktor yang menjadi penyebab utama yang mempengaruhi kelebihan biaya penyelesaian proyek pembangunan gedung markas komando daerah militer Manado Sulawesi Utara, yang berlokasi di kota Manado

Not ‘Islands, Entire of Themselves’: Exploring the Spatial Context of City-level Robbery Rates

The current study examines spatial dependence in robbery rates for a sample of 1,056 cities with 25,000 or more residents over the 2000–2003 period. Although commonly considered in some macro-level research, spatial processes have not been examined in relation to city-level variation in robbery. The results of our regression analyses suggest that city robbery rates are not spatially independent. We find that spatial dependence is better accounted for by spatial error models than by spatial lag models. Further exploration of various spatial weights matrices indicates that robbery rates of cities within the same state are related to robbery rates of other cities within the same state, regardless of their proximity. Our analyses illustrate how systematic inquiry into spatial processes can alert researchers to important omitted variable biases and identify intriguing problems for future research

Pixellated devices such as active matrix liquid crystal displays

A method of forming an active plate for a liquid crystal display is disclosed in which the source and drain conductors (28,30), pixel electrodes (38) and column conductors (32) are formed by depositing and patterning a transparent conductor layer. There is selective plating of areas (52; 60) of the transparent conductor layer to form a metallic layer for reducing the resistivity of the transparent conductor layer. The plated areas include the column conductors (32) but exclude the source and drain conductors and the pixel electrodes. This enables the column conductors to be treated to reduce the resistivity, but without altering the channel length of the transistor because the source and drain parts of the layer are shielded from the plating process

Luminous radio-quiet sources in the W3(MAIN) cloud core

We have resolved 450 micrometer and 800 micrometer emission from the W3(Main) star forming region into three major peaks, using 8 inch - 14 inch beams with the James Clerk Maxwell Telescope on the summit of Mauna Kea. One of the submillimeter sources is identified with W3 - IRS5, a well-known candidate protostar. However, to our surprise, we find that none of the submillimeter peaks coincides with any of the prominent compact HII regions in the area. We estimate that the three submillimeter sources together contribute 30-50 percent of the total bolometric luminosity of the region, and speculate that the contribution of luminous radio-quiet sources to the total luminosity of HII region/molecular cloud complexes may be larger than is often assumed

Salmonella Pathogenesis and Processing of Secreted Effectors by Caspase-3

The enteric pathogen Salmonella enterica serovar Typhimurium causes food poisoning resulting in gastroenteritis. The S. Typhimurium effector Salmonella invasion protein A (SipA) promotes gastroenteritis by functional motifs that trigger either mechanisms of inflammation or bacterial entry. During infection of intestinal epithelial cells, SipA was found to be responsible for the early activation of caspase-3, an enzyme that is required for SipA cleavage at a specific recognition motif that divided the protein into its two functional domains and activated SipA in a manner necessary for pathogenicity. Other caspase-3 cleavage sites identified in S. Typhimurium appeared to be restricted to secreted effector proteins, which indicates that this may be a general strategy used by this pathogen for processing of its secreted effectors

Attractiveness of periodic orbits in parametrically forced systemswith time-increasing friction

We consider dissipative one-dimensional systems subject to a periodic force and study numerically how a time-varying friction affects the dynamics. As a model system, particularly suited for numerical analysis, we investigate the driven cubic oscillator in the presence of friction. We find that, if the damping coefficient increases in time up to a final constant value, then the basins of attraction of the leading resonances are larger than they would have been if the coefficient had been fixed at that value since the beginning. From a quantitative point of view, the scenario depends both on the final value and the growth rate of the damping coefficient. The relevance of the results for the spin-orbit model are discussed in some detail.Comment: 30 pages, 6 figure

MESMER: MeerKAT Search for Molecules in the Epoch of Reionization

[Abridged] Observations of molecular gas at all redshifts are critical for measuring the cosmic evolution in molecular gas density and understanding the star-formation history of the Universe. The 12CO molecule (J=1-0 transition = 115.27 GHz) is the best proxy for extragalactic H2, which is the gas reservoir from which star formation occurs, and has been detected out to z~6. Typically, redshifted high-J lines are observed at mm-wavelengths, the most commonly targeted systems exhibiting high SFRs (e.g. submm galaxies), and far-IR-bright QSOs. While the most luminous objects are the most readily observed, detections of more typical galaxies with modest SFRs are essential for completing the picture. ALMA will be revolutionary in terms of increasing the detection rate and pushing the sensitivity limit down to include such galaxies, however the limited FoV when observing at such high frequencies makes it difficult to use ALMA for studies of the large-scale structure traced out by molecular gas in galaxies. This article introduces a strategy for a systematic search for molecular gas during the EoR (z~7 and above), capitalizing on the fact that the J=1-0 transition of 12CO enters the upper bands of cm-wave instruments at high-z. The FoV advantage gained by observing at such frequencies, coupled with modern broadband correlators allows significant cosmological volumes to be probed on reasonable timescales. In this article we present an overview of our future observing programme which has been awarded 6,500 hours as one of the Large Survey Projects for MeerKAT, the forthcoming South African SKA pathfinder instrument. Its large FoV and correlator bandwidth, and high-sensitivity provide unprecedented survey speed for such work. An existing astrophysical simulation is coupled with instrumental considerations to demonstrate the feasibility of such observations and predict detection rates.Comment: 7 pages, 4 figures, to appear in the proceedings of "Astronomy with megastructures: Joint science with the E-ELT and SKA", 10-14 May 2010, Crete, Greece (Eds: Isobel Hook, Dimitra Rigopoulou, Steve Rawlings and Aris Karastergiou
