Opis:
The Airy beams propagation in atmospheric turbulence along a slant path was simulated numerically, based on the split-step Fourier method. Also, the self-repairing and non-diffraction characteristics of Airy beams were investigated and compared with beams propagation on a horizontal path. The effects of parameters including zenith angle, propagation distance, radii of Gaussian aperture and turbulence intensity on the two characteristics of beams were revealed. Additionally, the two characteristics of the Airy beam were compared with those of a Bessel–Gauss beam. The results showed that the two beams obscured by Gaussian apertures can be repaired after propagating some distance along a slant path. However, the non-diffraction characteristic of an Airy beam was stronger than that of a Bessel–Gauss beam and the amplitude attenuation rate of the Bessel–Gauss beam was greater than that of the Airy beam in the process of self-repairing. Results obtained can provide a theoretical basis for an outdoor experiment as well as theoretical guidance for various practical applications including laser communications, laser warning systems, and remote sensing.

Opis:
In this study, carbon composite pellets were exposed to a reduction test under low temperature and semi-fusion conditions in which iron was melted without a solid form of slag deteriorated. The purpose of the reduction experiments under the semi-fusion condition was to produce an iron nugget which had physical and chemical properties similar to blast furnace pig iron at lower temperatures. These nuggets were produced from pellets that were made from a mixture of iron oxide, coke, flux, and a binder. These nuggets heated in a furnace with a chamber temperature of 1330 °C. The produced dried carbon composite pellets were melted and carbureted in a single-stage process. In this study, three distinct products were produced as a function of furnace residence time at fixed furnace temperature (1330 °C). These products were direct reduced iron (DRI), transition direct reduced iron (TDRI), and iron nuggets produced at residence times 8-24, 32-40 min, and 48 min, respectively. The iron nugget produced had a high apparent density (6.903 g/cm3), high micro hardness values (328 HV), high iron content (92.7% Fe), and was similar to blast furnace pig iron.

Opis:
The present study discusses the adsorption kinetics of arsenic(V) on granular ferric hydroxide (GEH) and the GEH adsorption capacity for arsenic(V) at equilibrium. The impact of temperature on GEH adsorption capacity was studied, as well as the effects of the initial concentration of arsenic(V) and GEH concentration on the adsorption rates of arsenic(V). The Freundlich isotherm describes the arsenic(V) adsorption behavior reasonably well (r2 > 0.965). The adsorption kinetics was studied by fitting the experimental data to both first-order and second-order models. The maximum adsorption capacity of arsenic(V) on GEH was 2.701 mg·g–1, which is higher than the adsorption capacities of other adsorbents reported. The kinetics of arsenic(V) adsorption was well defined by the second-order model, with the correlation coefficients in the range of 0.960–0.987. This study shows that due to its properties, GEH is a good candidate for removal of arsenic(V) from groundwater.

Opis:
A disparity servoing based fast autofocusing method is proposed for stereomicroscopes according to linear relationship between the disparity change in stereomicroscopic images and the move distance of a motorized translation stage. For a certain stereomicroscope, the calibration of a disparity range of clear images at each magnification is implemented offline. After that, the disparity of the stereomicroscopic image is used as an index to represent the sharpness of an arbitrary image. If the disparity does not satisfy the requirement, move steps and direction of a step motor are calculated by utilizing the linear relationship between the disparity change and the move distance of the stage. The iteration will be continued until the disparity of the captured stereomicroscopic image approximates to the clearest disparity. The experimental results show that the proposed method only requires a few iterations and less time to reach the focus position, and the disparity error is less than 0.5 pixel.

Opis:
Treating chalcopyrite flotation concentrates by hydrometallurgical techniques seems to be the most convenient method for leaching copper due to concerns over air pollution and regulations regarding the emission of sulfur dioxide that result from smelting. In this study, the leaching recovery-time trajectories of bulk chalcopyrite concentrate obtained from a flotation plant in the Kastamonu region of Turkey are presented. The effects of various parameters were elucidated in the nitrous-sulfuric acid electrolyte (CNaNO2:0.05 M–0.15 M, CH2SO4:1 M) at a moderate temperature (80–120 °C). A high level of copper recovery (98%) from bulk chalcopyrite concentrate was obtained under a total pressure of 6 atm at 120°C within 2 h when using small amounts of nitrite species due to their autocatalytic behavior in acidic solutions. The kinetics were well correlated with the shrinking core model for the diffusion controlled mechanism with an apparent activation energy of 34.06 kJ·mol–1. Elemental sulfur was the primary leaching product on the mineral surface, as confirmed using XRD and SEM/EDX. The semi-empirical equation explaining the reaction rate under the present conditions was expressed as follows: ...[wzór].

Opis:
Basing on the concept of circular economy, a novel method of industrial organic wastewater treatment by using adsorption on coal is introduced. Coal is used to adsorb organic pollutants from coking wastewaters. After adsorption, the coal would be used in its original purpose, as its value was not reduced and the pollutant was reused. Through the systemic circulation of coking wastewater zero emissions can be achieved. Lignite, coking coal and anthracite were used as adsorbents in batch experiments. The quinoline removal efficiency of coal adsorption was investigated. Both the coking coal and anthracite exhibited properties well-suited for quinoline adsorption removal. The experimental data were fitted to the pseudo-first- order and pseudo-second-order kinetic equations as well as intraparticle diffusion and Bangham models. An attempt was made to find the rate-limiting step involved in the adsorption processes. Both boundary-layer diffusion and intraparticle diffusion are likely involved in the rate-limiting mechanisms. Effect of pH on coal adsorptions by coking coal was investigated. The process of quinoline adsorption on coal was researched. The coal adsorption method for removing refractory organic pollutants is a great hope for achieving wastewater zero emission for coking plants.

Opis:
The demand for cobalt has increased significantly in recent years due to its use in a wide variety of products and processes. Cobalt and nickel often accompany each other in nature and close physicochemical properties of both metals make their separation a complicated practical problem. Organophosphorous extractants have been widely used to separate cobalt from nickel. This paper presents the preliminary results obtained for separation of cobalt from nickel using Cyanex 272 containing supported liquid membranes prepared by a novel ultrasound-assisted method. The results show that this novel supported liquid membrane preparation method leads to higher separation factors than those described in the literature under similar separation conditions.

Extraction times for selected metal cations (Mg2+, Al3+, Zn2+, Cd2+, Cu2+, Ni2+, Co2+, Mn2+, Fe2+ and Fe3+) have been measured using cation-exchanging extractants - Versatic 10 (neodecanoic acid), DEHPA (bis(2-ethylhexyl)phosphoric acid) and Cyanex 272 (bis(2,4,4-trimetylpentyl)phosphinic acid). Data was collected directly by measuring and recording pH of the two phase reaction mixture with maintaining continuity of the aqueous phase. Similarly, the stripping rate of selected cations (Mg2+, Al3+, Zn2+, Cu2+, Ni2+, Co2+) in a sulphuric acid solution was measured. Viscosities of organic phases, saturated with cations, were measured before their stripping. Additionally, the extraction dependence of Mg2+, Al3+, Fe2+ and Fe3+ on pH was measured using Versatic 10 at various concentrations (7.5, 15 and 30 %).

Opis:
Several copper extractants have been examined in laboratory glassware with a special attention paid to their behavior towards cations others than copper(II). In the studies 25 vol. percent of hydrocarbon (Exxsol D80 AZ) solutions of six industrial copper extractants have been used. They were mainly rea-gents of hydrooxime type (LIX 860N-IC, LIX 984, LIX 984N, LIX 84-I, Acorga M5640) and diketone type LIX 54-100. Individual isotherms of independent extraction of copper(II) and selected cations (Fe3+, Fe2+, Co2+, Ni2+, Zn2+, Mn2+, Cd2+, Mg2+) versus equilibrium pH have been compared. Investigations have been conducted with synthetic 0.1 mol/L solutions of their sulfates. The values of pH50% − parameter defined as an equilibrium pH at the moment of half-and-half extraction of the investigated cationic spe-cies have been presented. Also ΔpH50%, that is differences between values of pH50% for specific cation Me(II) and copper(II): ΔpH50% = pH50%(Me) − pH50%(Cu), have been given. In addition to that 25% LIX 984 has been used in counter-current pilot trials for copper(II) extraction from naturally contaminated solutions produced by bioleaching of industrial sulfide copper concentrate to observe behavior of investi-gated contaminants such as correlations between their real co-extraction with copper(II) and the position of their extraction on the pH scale. Copper electrolyte/strip solution, working alternately within close loop of coupled stripping - electrowinning system, has been analyzed during consecutive cycles to observe building up of the contaminants concentrations in the course of test.

Opis:
This paper presents proposed developments of a new formulation and a full algorithm for transient detection by applying Parks transformation. This approach consist in transforming three-phase voltage or current signals into Parks components known as direct, quadrature, and zero axes components. The input signals are local measurements of a power transmission or distribution system. Then, transients are superimposed in three-phase signals that can be detected in Parks components through the finite difference between samples. A full algorithm for the transient detection is presented and envisions the possibility of being applied in real time. In order to demonstrate the proposed algorithms performance, four case studies are considered: capacitor energizing, distribution transformer energizing, permanent resistive fault, and high impedance fault. These cases were simulated on a typical Brazilian sub-transmission line using Alternative Transient Program. As demonstrated by the case studies, the proposed formulation introduces further improvements for transient detection in power systems.

This study aimed to show the flotation behavior of a nickel sulfide ore in a cyclonic flotation column. The flotation experiments were carried out using a sample of nickel sulfide ore obtained from a mineral processing plant of China. Representative samples collected from the feed, concentrate, tailing, and circulation middling were sieved using a cyclonic particle analyzer to collect different size fractions for analysis. The function of the column cyclonic zone of was evaluated by comparing the quality of tailing and circulation middling. The flotation results showed that the concentrate with Ni grade of 1.78% and recovery of 65.56% was obtained under given test conditions. The content of main sulfide minerals and coarse particles in the circulation middling was higher than that in the tailing. The results indicated that, unlike conventional cyclone classification, separation achieved in the cyclonic zone of the column was not dependent on the particle size and density. Sulfide minerals with good floatability were easily captured by bubbles and moved toward the center of the column, even if these particles were coarser and heavier.

The paper presents results of studies on extracting properties of neodecanoic acid (Versatic 10) solutions. Neodecanoic acid was diluted in Exxsol D80 AZ to three concentrations: 7.5, 15, and 30 % (v/v). Tests were conducted using sulphate(VI) solutions of six ions: Zn(II), Ni(II), Cu(II), Co(II), Cd(II), Mn(II) and a nitrate(V) solution of Pb(II). All the aqueous solutions were prepared as 0.1 M concentration. For all combinations of the used solutions (organic and aqueous), direct methods of measuring and recording the pH of the biphasic mixture have been applied. The degrees of ions extraction, depending on equilibrium pH were also presented in the paper. Extraction and stripping isotherms of selected ions and organic phase were plotted for 7.5 and 30 % (v/v) of extractant solutions and Zn(II), Ni(II) and Cu(II) ions.

Purpose: In this work, the mechanical behavior of two block copolymers for biomedical applications is studied with particular regard to the effects induced by a steam sterilization treatment that biomedical devices usually undergo in healthcare facilities. This investigation is aimed at describing the elasto-plastic behavior of the stress-strain response, determining a functional dependence between material constitutive parameters, to obtain an optimal constitutive model. Methods: The mechanical properties of these polymers are analyzed through uniaxial tensile tests, before and after the sterilization process. The effect of sterilization on the mechanical behavior is evaluated. The Ramberg-Osgood model is used to describe the elasto-plastic behavior of the stress-strain response. Results: Data from uniaxial tensile tests are discussed in the light of previous data on the same polymeric materials, in order to highlight the correlation between physicochemical and mechanical properties variation. The material constitutive parameters are determined and the functional dependence between them is found, thus enabling an optimal constitutive model to be obtained. Conclusions: The effect of sterilization on the material constitutive parameters is studied, to evaluate the suitability of the model in describing the mechanical response of biomedical polymer before and after sterilization treatment. The same approach can be applied to other biomaterials, under various tensile tests, and for several processes that induce variation in mechanical properties.

Purpose: accurate assessment of human joint parameters is a critical issue for the quantitative movement analysis, due to a direct influence on motion patterns. In this study three different known functional methods are experimentally compared to identify knee joint kinematics for further gait and motion analysis purposes. Methods: taking into account the human knee physiology complexity, within its roto-translation, the study is conducted on a lower limb mechanical analogue with a polycentric hinge-based kinematic model. The device mimics a joint with a mobile axis of rotation whose position is definable. Sets of reflective markers are placed on the dummy and flexion-extension movements are imposed to the shank segment. Marker positions are acquired using an optoelectronic motion capture system (Vicon 512). Results: acquired markers’ positions are used as input data to the three functional methods considered. These ones approximate the polycentric knee joint with a fixed single axis model. Different ranges of motion and number of markers are considered for each functional method. Results are presented through the evaluation of accuracy and precision concerning both misalignment and distance errors between the estimated axis of rotation and the instantaneous polycentric one, used as reference. Conclusion: the study shows the feasibility of the identification of joint parameters with functional approaches applied on a polycentric mechanism, differently from those usually conceived by the reviewed algorithms. Moreover, it quantifies and compares the approximation errors using different algorithms, by varying number and position of markers, as well ranges of motion.
