The X-ray fluorescence cross-section for bromide and iodide compounds

The K$_\alpha$ and K$_\beta$ X-ray fluorescence cross-sections for the bromide and the iodide compounds were measured by a high-resolution Si(Li) X-ray detector. The vacancies were produced by heavily filtered 241Am gamma rays. We found that K$_{\alpha}$ and K$_{\beta}$ X-ray fluorescence cross-sections are changed by chemical effect for different Br and I compounds. Experimental results were compared with the calculated values of Br and I elements

A hybrid approach of data envelopment analysis based grey relational analysis: A study on egg yield

The aim of the study is to evaluate the effect of conditions of both feeding and the climate in poultry house on production performance in a commercial poultry enterprise with a hybrid approach. In accordance with this purpose, the hybrid approach has two main objectives: i) Determination of the effective period for which the output factors [(chicken survival rate (%), egg yield (%)] are optimized at the same time and the appropriate value ranges for the input factors [temperature (oC), humidity (%) and feed per hen (g)] that provide effectiveness ii) Determination of targeted improvement values for the ineffective months to become effective. With this hybrid approach, which is based on the integration of the Data Envelopment Analysis (DEA) and Grey Relational Analysis (GRA), the effective months are determined by DEA method and a performance rank is performed between the effective months by GRA method. It has been investigated whether the results of different Multicriteria Decision Making (MCDM) techniques combined with the data fusion technique support the proposed hybrid approach’s results. In this context, the proposed hybrid approach was applied to evaluate the monthly production performance of a commercial enterprise with Lohman Brown genus 8000 chickens. According to the findings of the analysis, it was seen that January, March, October, November and December are the months when production performance is high. When these months were ranked among themselves, it was observed that January, March and November are the first three ranks, respectively, and that the rank was also supported by the combined results of different techniques. As a result, in terms of production performance for the enterprise, it can be said that the optimum temperature is 20.25°C-26.41°C, humidity ratio is 47.60%-54.25%, and feed amount per hen is 98-128 g.

Measurement of M-shell X-ray production cross sections for the element 73 ≤ Z ≤ 83 using 5.96 keV photons

Total M-shell X-ray production cross sections (M XRF) of the some elements in the atomic number range 73 ≤ Z ≤ 83 were measured at 5.96 keV incident photon energy using a Si(Li) detector. The results are compared with the experimental and theoretical values in the literature

Chemical Effects on the Kβ\text{}_{β}/Kα\text{}_{α} Intensity Ratios in First-Row Transition Element Compounds

Chemical Effects on the K$\text{}_{β}$/K$\text{}_{α}$ X-ray Intensity Ratios for Some First-row Transition Element Compounds Were Studied Experimentally and Calculated. the Vacancies in the K Shell Were Created by 59.5 keV γ rays from an $\text{}^{241}$Am Radioactive Source and Characteristic X-ray Radiation from Sample Was Measured by Using Si(li) and Ge(li) Detectors. the Calculations Were Carried Out Using Brunner's Model. the Calculated Relative K$\text{}_{β}$/K$\text{}_{α}$ X-ray Intensity Ratios Are in Good Agreement with the Present and the Previously Published Experimental Data

Anisotropy of L-shell X-rays in Au and Hg excited by 59.5 keV photons

The anisotropy of emission intensity of L-shell X-rays induced by 59.5 keV photons in Au and Hg was investigated at different angles varying from 45° to 135°. It is observed that Ll and Lα X-rays (originating from J=3/2) are anisotropic, Lβ and Lγ X-rays (originating from J=1/2, commonly) are isotropic. © 1995 Società Italiana di Fisica

Measurement of X-ray production cross-sections of Ti, V, Cr, Mn, Fe, Co, Ni and Cu molecules

K shell X-ray production cross-sections in the Ti, V, Cr, Mn, Fe, Co, Ni, and Cu in the molecules were studied at 59.5 keV excitation energy by using a Si(Li) detector (${\rm FWHM}=155$ eV at 5.96 keV). The present results are compared with other theoretical values

Determination of Coster-Kronig transition probabilities (L1 › L2, L1 › L3 and L2 › L3) for Hg and Bi in molecules

The f12, f13 and f23 Coster-Kronig (CK) transitions (that is L1 › L2, L1 › L3 and L2 › L3 transitions) in Hg and Bi in molecules were studied at 59.5 keV excitation energy using an Si(Li) detector. A change in the CK transition probabilities was observed for different molecules. The change in the values for Hg compounds were greater than those for Bi compounds. Because we did not have pure Bi in the laboratory and also were not able to have specimen preparation conditions for pure Hg, we did not obtain experimental values for elemental Bi and Hg.
