This paper uses decomposition analysis and Tapio decoupling indicator to shed light on the role of reducing aggregate carbon emission intensity in decoupling economic growth from carbon emissions. The case study is Vietnam, a developing country with high carbon emissions per unit of GDP. Using data from the World Development Indicators by the World Bank, the research results show that low total carbon emissions growth and better decoupling status are achieved only in the years with a reduction in aggregate emission intensity.

Poverty and inequality are among the most discussed topics in Economics. This thesis aims to investigate the empirical relationship between financial inclusion, poverty and gender inequality. Using unique cross-country panel and survey data sets, three hypotheses are tested: (1) microfinance is an effective tool for poverty reduction; (2) women’s participation in microfinance contributes to improvements in gender equality; and (3) financial inclusion has a positive effect on household income in China.

In addition to the physical parameters such as magnetization intensity distribution, the volume and the shape of the magnetized material, directions of the magnetization and the ambient field, the distance between the observation surface and the causative sources significantly affects the shape and the amplitudes of the magnetic anomalies. Aeromagnetic surveys are performed using either a draped surface or a constant elevation plane above sea level. These surveys can easily reconnoiter large territories in a short time.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.

To evaluate the effect of the single energy metal artifact reduction (SEMAR) algorithm with a multide‑ tector CT (MDCT) for knee tumor prostheses. Methods: First, a phantom of knee tumor prosthesis underwent a MDCT scan. The raw data was reconstructed by iterative reconstruction (IR) alone and IR plus SEMAR. The mean value of the CT number and the image noise were measured around the prosthesis at the stem level and articular level.

In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.

In the present paper, firstly, we review our previous works on uncertainty quantification (UQ) of reactor physics parameters. This consists of (1) development of numerical tools based on the depletion perturbation theory (DPT), (2) linearity of reactor physics parameters to nuclear data, (3) UQ of decay heat and its reduction, and (4) correlation between decay heat and b-delayed neutrons emission.

Fourier transform infrared spectroscopy was performed on human leukemic daunorubicin-sensitiveK562 cells and their multiresistant counterpart derived by selection. Statistical analysis, including variable reduction and linear discrimi-nant analysis was performed on sensitive and multiresistant cells spectra in order to establish a diagnostic tool for multiresistant pattern. For each of the twomethods of data reduction tested [genetic algorithm or principal component analysis (PCA)] discriminationbetween the twocell lineswas found to be possible....

The nitrite reductase (Nir) isolated fromPseudomonas chlororaphisDSM 50135 is a blue enzyme, with type 1 and type 2 copper centers, as in all copper-containing Nirs des-cribed so far. For the first time, a direct determination of the reduction potentials of both copper centers in a Cu-Nir was performed: type 2 copper (T2Cu), 172 mV and type 1 copper (T1Cu), 298 mV at pH 7.6.
