Results and Discussions. In the present work we consider the effect of different impurities on the morphology of cementite nanowires. We have performed our modeling for both pure and doped nanowires oriented along different crystallographic axes. Mn and Si were chosen as the most common impurities (of course, apart from carbon) in ordinary steels, V is also used in the high-strength low-alloy steels [29] and P, S and V were experimentally found in DS [27, 28, 34]. The calculations were performed first for the ferromagnetic ground state of cementite. However, the morphology of cementite in steels at high enough temperature (in particular, above the ▇▇▇▇▇ temperature) is also of great interest. To study the effects of changes in magnetic state induced by the temperature, we have also performed calculations for disordered magnetic configurations [42, 43]. More specifically, calculations for three different randomly chosen spin configurations with the total magnetic moments equal to zero, which models the high-temperature paramagnetic state, have been performed for the bulk cementite and the nanowires. During the optimization of atomic structure we keep the chosen magnetic configuration. In all studied disordered configurations we have found a decrease of formation energies of cementite nanowires. For the smallest (1.24 nm) width of the nanowire oriented along the c axis it changes from 5.10 to 4.95 eV/Fe3C for the pure case, from 4.95 to 4.70 eV/Fe3C for P-doped J. Phys.: Condens. Matter 24 (2012) 395001 ▇ ▇ ▇▇▇▇▇▇▇▇▇▇ et al and from 5.21 to 5.13 eV/Fe3C for Mn-doped cases, in comparison with the ferromagnetic states. Thus, the degree of magnetic order of cementite plays an insignificant role in the energetics of the formation of pure and doped cementite nanowires. In contrast to elemental iron, the crystal structure of cementite is strictly anisotropic and can be described as a layered system with alternation of two iron and one carbon layers perpendicular to the crystallographic b axis (see figure 1). The axes in the cementite are chosen according to the standard denomination of the axes in the cementite lattice used in the previous works [28]. This special crystal structure determines the anisotropy of lattice distortions in the presence of impurities. Our calculations demonstrate that all impurities (Mn, V, Si, P, S) studied in this work produce an expansion of cementite along the a and c axes and an insignificant compression along the b axis. Substitution of a iron atom by silic...
Results and Discussions. To investigate the accuracy of the presented formulations, an example is chosen from Ref. [4], where the coupled thermoelasticity of a disk is analyzed using the finite element method. In this example, a stationary disk made of aluminum, with the Lamè constants λ = 40.4 GPa, μ = 27 GPa and α = 23 × 10−6 K−1, ρ = 2707 kg/m3, κ = 204 W/m·K and c = 903 J/kg·K is considered. The nondimensional inner and outer radii of the disk is given as a = 1 and b = 2, respectively. The inside boundary of the disk is assumed to be radially fixed, but exposed to a step function heat flux. The outside boundary is traction free with zero temperature change. The initial conditions for the displacement, velocity, temperature, and the rate of temperature are assumed to be zero. In the case of zero angular velocity, assuming that C = 0.02 and tˆ0 = 0.64, the time

2.2. Moreover, for these theories, the time histories of radial stress and tangential stress are plotted in Figs. 2.3 and 2.4, respectively. In this case, the reference temperature is considered to be 293 K. As shown in Figs. 2.2-2.4, when thermal shock load is applied, the generalized coupled theory based on LS model leads to larger maximum value of the curves for temperature, displacement and stresses compared to other theories. The classical coupled theory and uncoupled theories of thermoelasticity predict an infinite propagation speed for the thermal disturbances. In other words, when tˆ0 = 0 the hyperbolic heat conduction equation (2.11) reduces to a parabolic equation with infinite speed for thermal wave propagation. Moreover, this Fig. 2.2 shows that in the case of dynamic uncoupled solution, C = 0, the influence of temperature field on displacement filed is ignored and thus the radial displacement varies harmonically along the time with constant amplitudes. For couple...

Results and Discussions. Out of 39 centers, a total of 34 centers completed the survey. Two centers did not complete the survey because they were new clinics and were not treating patients at the time they received the survey. Figure 1 and Figure 2 show the demographics of the centers. The average number of medical physicists in the centers varied from 2 to 31. The average total number of staff per center with physics and engineering education as well as therapists varied from 12 up to over 240. The provinces of Ontario and Quebec have the largest average number of medical physicists and total staff followed by British Columbia and Alberta. Alberta has the largest average number of medical physicists per center. These data complements the results of a Canadian survey recently presented in this newsletter (▇▇▇▇▇ and ▇▇▇▇▇▇▇▇, 2011). Figure 3 shows the external beam modalities in which the centers treat cancer patients. These data show that in Canada there is a very large spectrum of clinics in terms of average number of staff. A total of 27 centers answered that they perform (to some extent) in-vivo dose measurements. From these 27 centers, 21 and 24 centers answered that they perform in-field and out-of-field in-vivo dose measurements, respectively. In Figure 1 we labeled with “yes / yes” the centers that measure in-vivo doses in-field and out-of-field, respectively. Figure 3 shows the treatment modalities in which in-vivo dosimetry are performed for. A total of 21 out of 34 centers perform in-field in-vivo dose measurements for static fields. From the 31 centers that treat using intensity modulated therapy (IMRT), 15 perform in-vivo dose measurements. For total body irradiation (TBI) treatments, 7 out of 9 centers perform

Results and Discussions. A borrow-to-use agreement is an agreement in which one of the parties (the creditor) benefits from the performance. The owner of the object or the one lending it does not gain any profits from the borrower during a borrow-to-use agreement. The willingness to help or to lend other party is possibly derived from an agreement, volunteering, solidarity, or a social sense of the object owner. Such things are every day occurences in Indonesian societies. The provisions regarding the a borrow-to-use agreement can be found in the Civil Code. The provisions regarding the borrow-to-use agreements can be found in the paragraph 1753 of the Civil Code. A borrow-to-use agreement is an agreement in which the lender hands in the object to be “used” until the agreed time is due. By then, the borrower must return the object to the lender. From the characteristic point of view, a borrow-to-use agreement in real, in which the lender hands in the object an object to the borrower and it is received by the borrower. Only then is the contract effective.

Results and Discussions. ▇▇▇▇▇’▇ Kappa interrater index is crucial to be undertaken after the experts had given their opinion on the item’s relevancy in research. The main reason the interrater index needs to be measured is to get a consensus among all the experts on the item’s relevance in the research. The ▇▇▇▇▇’▇ Kappa interrater index is like correlation coefficients, it can range from −1 to +1, where 0 represents the amount of agreement that can be expected from random chance, and 1 represents perfect agreement between the raters. As with all correlation statistics, the kappa is a standardized value and thus is interpreted the same across multiple studies. ▇▇▇▇▇ suggested the Kappa result be interpreted as follows: values ≤ 0 as indicating no agreement and 0.01– 0.20 as none to slight, 0.21–0.40 as fair, 0.41– 0.60 as moderate, 0.61–0.80 as substantial, and 0.81–1.00 as almost perfect agreement. In short, for this research, the value of the Kappa index should be at least 0.60. As this research investigates the factors that influence MTUN academic data sharing, thus four (4) constructs that have been identified were measured; technological, organizational, environmental, and individual. Each construct has its items to be measured. As shown in 2, the technological constructs resulted to get a substantial agreement of 0.78 in which the rate falls between 0.61 – 0.80. The organizational constructs resulted to get a substantial agreement of 0.78 in which the rate falls between 0.61 – 0.80. The environmental constructs resulted to get a perfect agreement of 1.00 in which the rate falls between 0.81 –1.00. The individual constructs resulted to get a substantial agreement of 0.80 in which the rate falls between 0.61 –0.80. It can be assumed that all of the constructs and its items measured were significant and agreed upon by the experts. Table 5shows a summary of the expert’s agreement for each construct. From this table, it can be seen that all of the experts were agreed with 95% to 100% with the items in the questionnaire and their significance to measure the dedicated constructs. The percentage is high and it makes the questionnaire fit to measure its purposes and it is validated. In this case, there will be no item removal at this phase and all of the items will be remained. The questionnaires now are ready to be distributed to MTUN academics for pilot study purposes.
