  • The paper "Aggregate indices method in soil quality evaluation using the relative soil quality index" presents a new approach to assess the soil quality by aggregate indices using the Relative Soil Quality Index (RSQI) proposed by Ho Ngoc Pham. RSQI is integrated from the individual indices into a simple formula for overall assessment of the soil quality. RSQI is different from other approaches.

  • The procedure is simple: to a known amount of sulfite in the polarographic cell (HAc, pH 6 or 7) is added an unknown Hg(II) sample. The Hg(II) concentration is calculated simply from the decrease in the sulfite peak after reaction with Hg(II). The limit of detection was 1 × 10 −6 M (S/N = 3) in this medium, which could not be obtained with most other mercury determination methods. The proposed new method exhibits high selectivity, sensitivity, reproducibility, and accuracy.

  • Titanium dioxide/phthalocyanine (TiO2/Pc), TiO2/fluor containing phthalocyanine (TiO2/FPc), and TiO2/fluor containing cobalt phthalocyanine (TiO2/FCoPc) had been successfully fabricated by a simple combination of phthalocyanines obtained by insitu synthesis on the surface of TiO2 nanofibers prepared by electrospinning. Scanning electron microscopy micrographs and X-ray diffraction analysis indicated that the phthalocyanines uniformly immobilized on the surface of TiO2 nanofibers.

  • Orobanche cumana is a parasitic plant that can lead to advanced losses in yield of agricultural lands cultivating sunflower, depending on the sunflower varieties and the level of contamination. In our study, genetic diversity of six O. cumana populations from the Thrace region of Turkey was determined with the help of eight SSR (microsatellite) loci. All SSR loci were polymorphic. A total of 23 alleles were determined for the analyzed 120 samples. Allele number of each SSR locus ranged from two to six. Mean number of alleles (Na = 2.271), effective allele number (Ne = 1.

  • This paper presents a design, calculation, simulation and fabrication of micro gripper driven by the electrothermal V-shaped actuator. The working principle of the V-shaped actuator bases on the thermal expansion of a thin beam when applying a voltage. The advantages of this design are large displacement amplification factor, large driving force, low voltage, simple configuration and control. The maximum displacement of each jaw can be up to 40µm at the calculated voltage of 17.35V and low operating frequency

  • In this paper, the authors propose to calculate the air-gap permeance by extending the overlapped area between the stator and its corresponding rotor tooth to the position where the permeance becomes zero. To examine the validity of the proposed approach, the results are compared with the ones obtained by the method in [12] and experimental measurements.

  • A Hybrid Spline Difference Method is developed to solve a nonlinear equation of welding problem in ultrasonic welding. It is shown that the method has a computational procedure as simply as the finite difference method. In addition, the proposed method can simplify complexity of the traditional spline method calculation, and increase accuracy of the first and second derivatives of space from O(Tx 2 ) of finite difference method to O(Tx 4 ).

  • A simple method using Fourier Transform Near-Infrared (FT-NIR) was investigated to determine quality of sugarcane/sugarcane juice in terms of ◦ brix value (total soluble solids), sucrose content (polarization %) and purity. Correlation equations for the chemometric models to predict the quality parameters of sugarcane juice were developed using partial least square (PLS) regression and were evaluated by cross validation and external test set validation to test their reliability for the calculation of ◦ brix (TSS), sucrose content and purity.
