In most of the investigation which have been made on wireless waves reflected from the ionosphere the experiments have been so designed as to provide information concerning the ionization density at different levels. The experimental data sought in such cases are usually critical penetration frequencies and equivalent heights of reflection. If, however, the amplitude of the downcoming waves is also observed, and the total absorption measured, it is possible to obtain information about the frequency of collision between electrons and molecules at different heights in the ionosphere. The measurements described in the present paper have been made so as to provide the latter type of information, and in particular to give evidence concerning the location of that part of the ionosphere which is of importance in producing absorption. For this purpose it is necessary to measure the absolute value of the absorption suffered by the wave, so that results on different wave-lengths may be compared. The methods which we have employed in making these measurements are described in § 2 and the results are discussed in § 4. The theoretical results which are used in § 4 are reviewed shortly in § 3. Most of the measurements discussed in this paper have been made on wave-lengths less than 200 m; a few measurements made with longer waves are discussed in § 6.

The experiment of the supstitution of soybean meal with raw soybean in the final diet was carried out on Hubbard F15 chickens at the age of 35- 42 days. The effect of different levels and varieties of raw soybeans in diets on carcass conformation and share of major carcass parts was determined in a twofactorial experiment 2 x 5 (2 soybean varieties x 5 levels of raw grains in the mixture), ie a total of 10 dietery treatments. At the end of the trial, by a random sample method, 12 chickens (6 males and 6 females) from each group were sacrificed and examined. The results showed that the index of drumstick girth and share of drumstick were under significant (p<0.05) influence of the soybean varieties. The level of raw soybeans in diets had significant effect (p <0.05) on the index of drumstick girth and on the absolute value of the breast depth and breast angle. Shares of breast and thighs of broiler chickens of both sexes were not significantly influenced by the studied factors. It was concluded that the share of raw soybean of 10, 15 and 20% in the final mixtures for broilers hinders the utilization of protein in the ration, resulting in poorer quality of chicken carcasses.

Abstract 1. The heat of vulcanization of the system: pure rubber-sulfur is determinated. 2. The absolute value of the experimental data is in doubt, however, since the results were widely different from those of Blake. 3. The experimental results are discussed. 4. The results of Blake are discussed. 5. The difference from the results of Blake is attributed to the difference in the content of resinous substances in the sample.

In this paper, coupled with preconditioning technique, a preconditioned accelerated over relaxation (PAOR) iterative method for solving the absolute value equations (AVEs) is presented. Some comparison theorems are given when the matrix of the linear term is an irreducible [Formula: see text]-matrix. Comparison results show that the convergence rate of the PAOR iterative method is better than that of the accelerated over relaxation (AOR) iterative method whenever both are convergent. Numerical experiments are provided in order to confirm the theoretical results studied in this paper.

The aim of this communication is to present the results of an experimental research on the intensity of the radio emission of the Moon at 4 mm and to describe the method followed in observations and reductions. It was established that the radio brightness of the Moon,Tl, varies during the lunation according to the law:Tl= 230° + 73° cos (Ω0t-24°)K. The accuracy in measuring the absolute value of Moon's radio temperature is about ± 10%. The comparison between the phase dependence of the radio emission of the Moon at 4 mm and the data from observations of the radio temperature of the lunar disk on other wave lengths demonstrated that the homogeneous model of Moon's surface is in good agreement with the experimental data.

A number of different methods have been suggested in the literature for using HREM in a quantitative fashion, including R factors and cross-correlation analyses. The problem with many of these is that it is difficult to realistically gauge the errors involved when they are applied to real systems. For instance, R-factors defined by:(1)(where n=1 or 2 and Ic is the calculated image, Ie the experimental data) assume a signal independent error. Furthermore, the absolute value of R is strongly dependent upon background levels which is misleading.

This paper presents the principles of the transistor compensation technology of temperature coefficient of sensitivity (TCS) of pressure sensor. A quantitative compensation formula is demonstrated in mathematics. By experiments, the absolute value of the compensated TCS is easy to be 10×10－6/°C～100 ×10－6/°C with individual adjustment and calibration of each device’s temperature compensation. The feasibility and practicability of this technology are tested. The disadvantages are discussed after the research of the experimental data, while the improvement methods are also given in the designing period. This technology exhibits the great potential practical value. These applications are promoted in the volume production. The operating performances of these pressure sensors using this technology are studied and proved they are reliable and stable.

Operational Expenditure

This study aims to analyze the sensitivity testing using measurements of realization of regional own-source revenues and operating expenditure and to analyze the extent of the effect of sample differences between Java and non-Java provinces by using samples outside of Java. By using sensitivity analysis, the results found the influence of audit opinion on the performance of the provincial government mediated by the realization of regional operating expenditure. More specifically, when using the measurement of the absolute value of the realization of regional operating expenditure it was found that there was a direct positive and significant influence of audit opinion on the performance of the Provincial Government. However, no significant effect of audit opinion was found on the realization value of regional operating expenditure and the effect of the realization value of regional operating expenditure on the performance of the Provincial Government. This result implies that an increase in audit opinion will be more likely to be used as an incentive for the Provincial Government to increase the realization of regional operating expenditure.

This study aims to examine the consequences of International Financial Reporting Standards (IFRS) convergence in an emerging market. More specifically, we investigate whether the adoption of the new set of accounting standards in Malaysia is associated with lower earnings management. Using a sample of 3,340 firm-year observations across three reporting periods with different levels of IFRS adoption, we provide evidence that IFRS convergence improves earning quality. In particular, we find a significant decrease in the absolute value of discretionary acccruals in the partial IFRS-convergence period (2007-2011), whereas this effect is restrictive after the complete IFRS- implementation.

Abstract The influence of five different methods of homogenisation (1. The method according to Potter and Elvehjem, 2. A modification of this method called Potter S, 3. The method of Dounce, 4. Homogenisation by hypersonic waves and 5. Coarce-grained homogenisation with the “Mikro-fleischwolf”) on the absolute value and stability of oxygen uptake of guinea pig liver homogenates has been investigated in simultaneous measurements. All homogenates showed a characteristic fall of oxygen uptake during measuring time (3 hours). The modified method according to Potter and Elvehjem called Potter S showed reproducible results without any influence by homogenisation intensity.
