“…The data of Sun et al, 12 Watanabe and Seong, 13 Watanabe, 17 Assael and Dalaouti, 14 Assael et al, 20 Perkins et al, 15,21 Lei et al, 16 Ramires et al, 18,22 Yamada et al, 19 Taxis et al, 23 Charitidou et al, 24 Nieto de Castro et al, 26 and Nagasaka and Nagashima, 28 were all performed in transient hot-wire instruments in an absolute way, exhibited very low uncertainty (typically 60.5%), and fulfill the aforementioned criteria for primary data. The data of Wu et al 10,11 and Kashiwagi et al, 27 performed also in transient hot-wire instruments but of slightly higher uncertainty, were also included in the primary data sets. In addition to these sets, some more sets were included; while they only partially fulfill the aforementioned criteria, they extend the temperature and pressure ranges of application.…”

This paper contains new, representative equations for the thermal conductivity of toluene. The equations are based in part upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory whenever possible. Although there are a sufficiently large number of data at normal temperatures, data at very low and very high temperatures as well as near the critical region are scarce. In the case of the dilute-gas thermal conductivity, a theoretically based correlation was adopted in order to extend the temperature range of the experimental data. Moreover, in the critical region, the experimentally observed enhancement of the thermal conductivity is well represented by theoretically based equations containing just one adjustable parameter. The correlations are applicable for the temperature range from the triple point to 1000 K and pressures up to 1000 MPa. The overall uncertainty (considered to be estimates of a combined expanded uncertainty with a coverage factor of two) of the proposed correlation is estimated, for pressures less than 700 MPa and temperatures less than 550 K, to be less than 3% for the liquid, while for the region 550 K ≤ T ≤ 700 K the uncertainty is estimated to be 4%. For the region T > 700 K and 500 MPa ≤ p ≤ 1000 MPa, the equations can safely be used with an uncertainty of the order of 10%. Finally, the uncertainty along the saturation line is estimated to be 2% with a coverage factor of two.

“…In that respect, using irradiation, current estimates indicate that more than 2,200 varieties of plants were already obtained. It is noteworthy that 64% of these were obtained by gamma radiation (AHLOOWALIA et al, 2004;WU et al, 2005). With regards to irrigated rice, the introduction of cultivars ClearField (CL) obtained by induced mutation, has led to higher yields coupled with the better control of red rice (FAGUNDES; ANDRES, 2008).…”

Techniques used to induce mutations, such as ionizing radiation, are an effective tool in increasing genetic variability in breeding programs of species of economic interest. This study aimed to evaluate the effect of different doses of Co60 gamma radiation on previously soaked seeds on the emergence and early growth of seedlings of two rice cultivars. To do this, seeds (25% moisture) of BRS Querência and BRS Fronteira were irradiated with zero (control), 50, 100, 150 and 200 Gy, and then sown in trays containing soil and kept in a greenhouse. The results showed that gamma radiation affected seedling development, where the highest dose tested (200 Gy) significantly reduced the emergence and the index of emergence speed. Growth parameters were reduced greater reduction in cv. BRS Querência. For antioxidant enzymes, superoxide dismutase expressed little variation for the periods evaluated. Already ascorbate peroxidase and catalase showed a significant increase in horsepower cv. BRS Fronteira at 14 DAS, followed by an increase in both cultivars ascorbate peroxidase activity at 28 DAS. The highest antioxidant capacity observed in cv. BRS Fronteira conferred greater tolerance to stress caused by gamma radiation.

Measurements of the density and viscosity of dimethoxymethane and 1,2-dimethoxyethane are reported over the temperature range from 243 K to 373 K and at pressures up to 20 MPa. The measurements were performed simultaneously using a vibrating-wire instrument operated in the forced mode of oscillation. The overall uncertainties of these results are 2.0 % in viscosity and 0.2 % in density. The measurements were correlated with a Tait-type equation for density and a hard-sphere model for viscosity. The maximum absolute deviation and the average absolute deviation (AAD) of the density measurements from the correlation for dimethoxymethane are 0.065 % and 0.012 %, respectively, and for 1,2-dimethoxyethane, are 0.16 % and 0.044 %. With regard to viscosity, the maximum absolute deviation and the AAD of the present results from the correlation for dimethoxymethane are 1.55 % and 0.40 %, respectively, and for 1,2-dimethoxyethane, are 1.05 % and 0.26 %. Comparisons of the experimental data and measurements from the literature with values calculated by the correlations at different temperatures and pressures are presented.
