Almost Forgotten Research Contexts: William Stern's Giftedness Research.

This article examines the concept of intelligence and giftedness of the German psychologist and philosopher William Stern, the leading intelligence and giftedness researcher in Germany from the early 20th century to 1933. Stern developed a multifactorial giftedness model that integrated empirical and philosophical perspectives and was thus far ahead of his time. This concept was not taken up for a long time-not least because of the break that the research on giftedness suffered in Germany in 1933-and has not yet been presented with the required complexity and interdisciplinarity.

Inorganically modified particles FeAl-LDH@SiO as reinforcement in poly (methyl) methacrylate matrix composite.

Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe-Al layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios Fe : Al of 3 : 1 in the presence of SiO particles from the rice husk. Characterization of the synthesized FeAl-LDH@SiO particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS.

Sequential Laser-Mechanical Drilling of Thick Carbon Fibre Reinforced Polymer Composites (CFRP) for Industrial Applications.

Carbon fibre reinforced polymer composites (CFRPs) can be costly to manufacture, but they are typically used anywhere a high strength-to-weight ratio and a high steadiness (rigidity) are needed in many industrial applications, particularly in aerospace. Drilling composites with a laser tends to be a feasible method since one of the composite phases is often in the form of a polymer, and polymers in general have a very high absorption coefficient for infrared radiation. The feasibility of sequential laser-mechanical drilling for a thick CFRP is discussed in this article.

Development of Laser Drilling Strategy for Thick Carbon Fibre Reinforced Polymer Composites (CFRP).

Composites from carbon fibre reinforced polymers (CFRPs) play a significant role in modern manufacturing. They are typically used in aerospace and other industries that require high strength-to-weight ratios. Composite machining, however, remains a challenging job and sometimes is hampered by poor efficiency.
