Studies in Canarium urceus (Linnaeus, 1758) Part 6: A new Canarium species from the Andaman Sea (Gastropoda: Strombidae) and discussion on related species

This part of the Canarium (Canarium) urceus-complex (Linnaeus, 1758) review after Abbott’s revision (Abbott, 1960) revision examines material from the Andaman Sea. At present, material from that region has been synonymised under the name Canarium (Canarium) urceus (Linnaeus, 1758). Canarium (Canarium) andamanense new species is known from the Andamanian Subprovince, a semi enclosed basin that is centered on the Andaman Sea and enclosed by the west coasts of Myanmar and Thailand and the Mergui Archipelago in the east, to the northern Malacca Strait in the south, and to the Andaman and Nicobar Islands in the west. This species is recognized and differentiated by solid, sturdy shells with a triangular body whorl, large knobs on the shoulder and bright orange aperture. This study further confirms that there is a high degree of bioregionalisation within the Canarium complex.

UTILIZATION OF GEOGRAPHIC LEARNING MEDIA BASED ON CHARACTER EDUCATION IN THE ERA OF THE DIGITAL REVOLUTION

The world is facing the era of industrial revolution 4.0, where everything is connected to machines. In realizing human resources that are ready for the era of the industrial revolution 4.0, the government makes several efforts through education. Character is one of the cornerstones of the progress of a nation. Character is not inherited from birth but needs to be nurtured to grow into the nation's character. The character can be formed through school education in geography subjects. Learning geography will introduce students to the area where they are located. Thus, geography can develop religious, nationalist, independent, cooperative, and integrity characters who love the homeland. This study aims to determine the character of students in the development of character-based learning media. This research was conducted at the Geography MGMP of SMA in Langsa City and East Aceh Regency, totalling 27 teachers. Data collection techniques are interviews and information on the types of learning media on geography material in high school and the characters needed to study geography. The research results are (1) Teachers choose 83% of high school geography materials that require video as a learning medium. Videos are considered capable of providing explanations in the form of images with movement and sound. Thus, videos can help students understand geography material; (2) Interactive multimedia is a suitable medium to foster independent character in students. This media is interactive where the media will present material or information according to what students want; therefore, teachers must develop interactive multimedia for their students; (3) Teachers have the same difficulty in developing geography learning media. The difficulty is the lack of skills in the use of IT technology.Keywords: Learning Media, Character Education, Geography Education, Digital Revolution

Tissue-like skin-device interface for wearable bioelectronics by using ultrasoft, mass-permeable, and low-impedance hydrogels

Hydrogels consist of a cross-linked porous polymer network and water molecules occupying the interspace between the polymer chains. Therefore, hydrogels are soft and moisturized, with mechanical structures and physical properties similar to those of human tissue. Such hydrogels have a potential to turn the microscale gap between wearable devices and human skin into a tissue-like space. Here, we present material and device strategies to form a tissue-like, quasi-solid interface between wearable bioelectronics and human skin. The key material is an ultrathin type of functionalized hydrogel that shows unusual features of high mass-permeability and low impedance. The functionalized hydrogel acted as a liquid electrolyte on the skin and formed an extremely conformal and low-impedance interface for wearable electrochemical biosensors and electrical stimulators. Furthermore, its porous structure and ultrathin thickness facilitated the efficient transport of target molecules through the interface. Therefore, this functionalized hydrogel can maximize the performance of various wearable bioelectronics.

Composites for Life

The usage of bio-fibres and recycled materials is a growing approach to address the ecological problems being faced today. Inspired by the guidelines defining the Waste for Life initiative, the present study reports new composite materials, based on the recycling of high-impact polystyrene, found, for instance in yogurt cups, and paper plastic laminates, deriving from disposable paper cups. Given their recycling incompatibility, paper plastic laminates are either dumped in landfills or incinerated after their first usage, threatening the environmental condition. Therefore, through the development of a new composite solution, the goal was to reduce this damaging environmental impact by providing a second life to both paper plastic laminates and high-impact polystyrene. Samples presented overall good mechanical properties, from which it is highlighted a Young’s Modulus of 1.75 GPa and a Tensile Strength of 21.2 MPa, encouraging the application of the present material to identified global obstacles.
