Measurement of the Thermal Conductivity of Powders by Two Different Methods

The thermal diffusivities and thermal conductivities of powders, especially PMMA-coated silicon carbide, at various temperatures, have been tested by two different dynamic methods, the water-bath method and the laser-heated method. The thermal conductivity data found by these two techniques are found to be consistent with each other.Mechanical Engineerin

Models for the Prediction of the Thermal

Five models and eq\1ationsJorthe.predictic;>nof the tbertnal conduc~"ities of powders in the literature are compared with the data obtainedill the experiments of the authors. Anew modified ntodel for the. correlation of the experimental data is presented. Key words: differential scanning calorimetry, porosity, solid content, specific heat, thermal conductivity.Mechanical Engineerin

The Measurement of the Thermal Properties and Absorptances of Powders Near their Melting Temperatures

A new technique, using a laser as the heating source, has been adopted to measure the heat capacities, thermal diffusivities, thermal conductivities, and absorptances of powders (especially polymer powders) near their melting temperatures. This makes use of an unsteady state process. The data of the thermal conductivities obtained through this technique below 100°C are in concord with the values obtained through the other techniques, which predicts well for the use of this technique for still higher temperatures, up to the melting temperatures of the powders to be investigated.Mechanical Engineerin

Persuasive Strategies Used in Jokowi's Speech in His Governor Election Campaign

This present study is conducted to find out the types of persuasive strategies which were used in Jokowi's speech. This study is aimed to seek the types of persuasive strategies and also the speech function related to the persuasive strategies used by Jokowi. This study is supported by Beebe & Beebe's theory of persuasive strategy (2012) and Holmes theory of speech function (1996). The writer analyzed the speech in a standup comedy used in Jokowi campaign in 5th October 2012. The writer found eight characteristics of persuasive strategies that Jokowi used: using evidence to tell a story , considering using appeals to several emotion (hope, courage, pride,) using specific evidence, using appropriate fear appear, using new evidence, and using concrete example that help your listener visualize what you describe. The writer also found the speech function that related in persuasive strategies in Jokowi's speech as being referential, directive, metalinguistic, expressive, and phatic

A Marketing Booklet for Brotherwood Decoration: a Way to Promote This New Company and Its Products to Its Prospective Customers

Brotherwood Decoration is a new decoration company based in Surabaya which uses recycled wood as the main material. This Company was just recently established in June 2014. As a new decoration company, there are only a few people who know about this company. Moreover, there are also some decoration companies which are bigger and more experienced than Brotherwood Decoration. Unlike its predecessors, Brotherwood Decoration, as a new company, is less known. Because of that, it does not have as many customers as its predecessors. Therefore, it is better for Brotherwood Decoration to start showing its strengths to more people. To accomplish the goal, a marketing booklet is the best solution to solve the problem in Brotherwood Decoration. There are four parts in this marketing booklet: table of contents, company overview (“About Brotherwood Decoration”), products (“Products”), and company contact information (“Contact Us”). By having these information, the marketing booklet will be able to help Brotherwood Decoration in introducing its hotel, getting more customers, increasing its revenues, and becoming a big decoration compan

Quantization of anomaly coefficients in 6D N=(1,0)\mathcal{N}=(1,0) supergravity

We obtain new constraints on the anomaly coefficients of 6D $\mathcal{N}=(1,0)$ supergravity theories using local and global anomaly cancellation conditions. We show how these constraints can be strengthened if we assume that the theory is well-defined on any spin space-time with an arbitrary gauge bundle. We distinguish the constraints depending on the gauge algebra only from those depending on the global structure of the gauge group. Our main constraint states that the coefficients of the anomaly polynomial for the gauge group $G$ should be an element of $2 H^4(BG;\mathbb{Z}) \otimes \Lambda_S$ where $\Lambda_S$ is the unimodular string charge lattice. We show that the constraints in their strongest form are realized in F-theory compactifications. In the process, we identify the cocharacter lattice, which determines the global structure of the gauge group, within the homology lattice of the compactification manifold.Comment: 42 pages. v3: Some clarifications, typos correcte

Self-Maintained Coherent Oscillations in Dense Neutrino Gases

We present analytical solutions to the nonlinear equations describing the behavior of a gas of neutrinos with two flavors. Self-maintained coherent flavor oscillations are shown to occur when the gas density exceeds a critical value determined by the neutrino masses and the mean neutrino energy in the gas. Similar oscillations may have occurred in the early Universe.Comment: To appear in Physical Review D, July 199
