Background & Aims: Cement industry is very contaminated. Contaminants resulting from industries include dust, carbon compounds, sulfur and nitrogen. The purpose of this study was to evaluate the output of pollutants from cement plants in soil samples and leaf tree species. Methods: This study descriptive-analytic was designed tree species, plants and soil around the plant. Samples from four different stations within 500 meters of factory and 21 packages (each package contains three examples of the sample) were sent for laboratory tasks. Information of sampling stations in the soil, the plants and factories of qualitative and quantitative tests on samples of soil pollutants output of factories, plant species and trees daily and using written lists were collected. After the sampling, the samples were measured using standard methods and analyzed using statistical software. Results: Distribution of the total amount of metals in oak and black plants and reed Talo is normal and can be used for parametric tests. Also, there is no significant relationship statistically among the total amount of metals in plants such as oak trees, reed and Siah Talo. Conclusions: According to the findings of this study, we can conclude that dust subsides the leaves of three species of oak and black Talo and reed which contain considerable concentrations of metals such as silver, barium, bismuth, cesium, chromium, cobalt, cadmium and arsenic.

Synthesis and characterization of niobium-promoted cobalt/iron catalysts supported on carbon nanotubes for the hydrogenation of carbon monoxide

燃料化学学报 2016年第7期44卷 815-821页

作者： Zahra gholami Noor Asmawati Mohd Zabidi Fatemeh gholami Mohammadtaghi Vakili Centralized Analytical Laboratory Universiti Teknologi PETRONAS Department of Fundamental and Applied Sciences Universiti Teknologi PETRONAS Department of Mechanical Engineering Faculty of EngineeringUniversity of Malaya School of Industrial Technology Universiti Sains Malaysia

Bimetallic Co /Fe catalysts supported on carbon nanotubes( CNTs) were prepared,and niobium( Nb) was added as promoter to the 70 Co ∶30Fe /CNT catalyst. The physicochemical properties of the catalysts were characterized,and the catalytic performances were analyzed at the same operation conditions( H_2 ∶CO( volume ratio) = 2 ∶1,p = 1 MPa,and t = 260 ℃) in a tubular fixed-bed microreactor system. The addition of Nb to the bimetallic catalyst decreases the average size of the oxide nanoparticles and improves the reducibility of the bimetallic catalyst. Evaluation of the catalyst performance in a Fischer-Tropsch reaction shows that the catalyst results in high selectivity to methane,and the selectivity to C_(5+) increased slightly in the bimetallic catalyst unlike that in the monometallic catalysts. The addition of 1% Nb to the bimetallic catalyst increases CO conversion and selectivity to C_(5+). Meanwhile,a decrease in methane selectivity is observed.

Some Explicit Constructions of Type-Ⅱ,Ⅲ,Ⅳ,Ⅴ QC-LDPC Codes with Girth 6

引用

China Communications 2020年第5期17卷 89-109页

作者： Farzaneh Abedi Mohammad gholami Department of Mathematics Shahrekord UniversityP.O.Box 88186-34141ShahrekordIran School of Computer Sciences Institute for Research in Fundamental Sciences(IPM)P.O.Box 19395-5746TehranIran

Multi-type quasi-cyclic(QC) low-density parity-check(LDPC) codes can be considered as multiple-edge protograph QC-LDPC codes having some advantages in the minimum Hamming distance bound over single-edge protograph codes or type-Ⅰ QC-LDPC codes when the base matrices have the same size. In this paper, we investigate a class of multi-type QC-LDPC codes whose parity-check matrices contain just one blockrow of circulants and we obtain the generator matrix of such codes in general form. Using the permutation arrays and defining injection arrays, we present a new approach to construct a class of high-rate type-Ⅰ QC-LDPC codes with girth 6 from the constructed 4-cycle free multi-type QC-LDPC codes. In continue, for 2 ≤ w≤6, some type-w QC-LDPC codes with girth 6 are constructed explicitly such that the constructed codes are flexible in terms of rate and length. To the best of our knowledge, for w = 5,6, this is the first paper which deals with the explicit construction of type-w QC-LDPC codes with girth 6 and high rates. Moreover, for w = 3, 4, the constructed type-w QC-LDPC codes have better(6,8)-cycle multiplicities than the codes with minimum achievable length recently constructed by cyclic difference families(CDFs). Simulation results show that the binary and non-binary constructed codes outperform the constituent underlying QC-LDPC codes.
