In this study, the seismic response of a container crane under a ground motion was investigated by using shake table testing on a 1/20 scale container crane. The 1/20 scale container crane was designed and fabricated according to the similitude laws, utilizing three independent quantities such as geometric length, acceleration, and elastic modulus were used to design the 1/20 scale container crane.

Several experiments were conducted in a drying chamber, with Natto as the test material. These experiments involved varying the number of trays and the angle of the trays to determine the most appropriate configuration, verify the uniformity of air distribution in the equipment, and evaluate the uniformity of the average moisture reduction of Natto seeds in each batch compared to the established theory in the previous study.

The study analyzes images that have been cultivated by ancient cultural memories to become Korean cultural symbols, such as the model of women, the space containing the sediments of the times, and the way of life in daily activities and beliefs as a model of practice. Through that, the research wants to clarify the two major functions of these cultural symbols: shaping the national cultural identity and becoming a measure of valuation for contemporary perceptions of human dignity.

This paper aims to study the effect of coal bottom ash (CBA) as a fine aggregate substitution at high levels on the mechanical properties and microstructure characteristics of concrete. CBA that sourced from a local coal-fired power plant in Vietnam was used to replace the natural sand (NS) in the concrete mixtures at different levels of 0, 30, 50, 70, and 100%.

The paper "Hardware implementation for entropy coding and byte stream packing engine in H.264/AVC" propose hardware architecture of entropy encoding and byte stream data packing engines for the H.264/AVC. Our entropy coding engine, that contains Exp-Golomb and Context-Adaptive Variable Length Coding (CAVLC), supports baseline and main profile of the standard. The proposed architecture is implemented using 180nm technology from AMS. The design consumes only 1.56mW at the operating frequency of 100MHz.

The samples were synthesized in two steps containing the photochemical reduction and galvanic replacement reaction using silver nanodecahedra as a sacrificial template to obtain hollow silver-gold alloy nanoshells. The dimension of the hollow cavities can be controlled by varying the amount of HAuCl4. The prepared Ag/Au decahedra can be applied to the SERS analysis.

Water quality plays an immensely significant role in safeguarding the health of humans and other species on the planet. Polluted water sources can contain harmful substances such as heavy metals, pesticides, bacteria, and viruses, which can pose threats to human health and other organisms. Water quality is also a crucial factor in protecting the environment and sustaining the ecosystems of freshwater and marine environments. Polluted water sources can impact the lives of aquatic animals and plants, causing harm and endangering biodiversity by disrupting the food chain.

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate.

This study outlines a nanotechnology-based method to enhance its solubility and absorption of rosuvastatin. The process entails the formulation of rosuvastatin nanoparticles through a combination of precipitation and ultrasonic techniques. Rosuvastatin is initially dissolved in an organic solvent, such as acetone, and subsequently mixed with an aqueous phase containing stabilizers like Poloxamer 407 or PVP to induce precipitation. Ultrasound reduces particle size to 50-200 nm.

A procedure for quantitative analysis of trace element magnesium (Mg) in soft capsules (mainly containing vitamins, trace elements and herbal extracts) using atomic absorption spectroscopy (AAS) has been established. The sample was treated to convert the Mg compound to Mg+2 ion form in solution by heating the sample on a boiling water bath with 10% hydrochloric acid solution, with the addition of Polysorbate 80. The sample was diluted with 1% hydrochloric acid solution, with the addition of LaCl3 in the final solution for AAS measurement.
