“…Starch is the main carbohydrate ingredient of human food in addition to the protein. Starches, including modified starches, are important ingredients of various industries and are used for numerous applications including food, fermentation, textile, cosmetics, pharmaceuticals, packaging, synthetic polymer industries, and more. , Modified starches and different native starch-based blends are an attractive bio-based alternative to biodegradable synthetic polymers. , Starch-based bioplastics represent 80–85% of marketed bioplastic . In addition, starch from cereals is used for biofuel production for the past 10 years in the United States and has also become prominent in other parts of the world .…”

Marine macroalgae are an attractive source for biorefineries as an alternative to terrestrial crops, and new, sustainable macroalgae biomass fractionation methods are needed. One of the least investigated macroalgae-derived products is starch. In this work, we report on a device and a protocol for pretreatment for starch extraction from a green macroalga Ulva ohnoi (U. ohnoi) with an emerging, nonthermal, and environmental friendly technologypulsed electric field (PEF). Using the custom-made insulated gate bipolar transistor-pulsed generator combined with a gravitation press-electrode device, we show that 200 pulses with a field strength of 1 kV cm −1 , pulse duration of 50 μs, and pulse repetition rate of 3 Hz concentrate the starch in the U. ohnoi biomass by 59.38% by removing the salts, proteins, and other small molecules. The starch extraction yield from the PEF-pretreated biomass is 59.54 ± 1.34%, compared to 52.31 ± 3.21% from untreated biomass. In addition, PEF combined with pressing increased the coextracted macroalgae protein by more than 4 times and ash by 1.5 times in comparison with pressing alone. These results indicate the potential of PEF pretreatment for challenging macroalgae biomass fractionation in the sustainable marine biorefinery.

“…156 This success at producing foreign-designed weaponry, however, lulled South African leaders into a false sense of security, believing that they had achieved "self-sufficiency" and could henceforth design new weaponry "at the forefront of technology." 157 Escalating threats in the mid-1970s demonstrated that foreign-designed weaponry was ill-suited to the challenges South Africa faced. Vast unpaved roads, firstly, offered insurgents ideal opportunities for laying anti-vehicle mines and ambushing communications arteries.…”

Armaments after autonomy: Military adaptation and the drive for domestic defence industries

State investments in domestic defense industries are one of the most puzzling trends in international relations. Over 60 states devote scarce assets to such industries. Economists contend that these investments waste resources because most states could procure their weaponry more cost-effectively from international markets. Political scientists, furthermore, claim that the resulting overproduction of armaments fuels arms races. Why then do governments cultivate domestic defence industries and what benefits do they provide? I argue in the following pages that the answers to these questions are distinct. Fears about supply security frequently spur states to begin developing arms industries and elites' technonationalist beliefs often sustain their defence-industrial investments. Defence industries' primary national security value, however, lies in their hitherto unappreciated contribution to states' military adaptation capacity. Since warfare is unpredictable, victories are oftentimes won by whichever side adapts faster to battlefields' unexpected realities. Even small defense industries, within these circumstances, boost states' capacity for military adaptation. Cases drawn from Israel's, South Africa's and Iraq's experiences demonstrate both military adaptation's role in driving governments to sustain their investments in domestic defense industries as well as the complementary impacts of supply security and technonationalist considerations.

“…Lack of clarity in conductor movements, such as deviation from the accepted path or inconsistent placement of an ictus, has been shown to disrupt and hamper a musical performance [7]. It is also qualitatively known that deviation from the conventional path can be caused by extraneous body movement [8]. However, there is currently no research that quantitatively visualises and analyses the effect of extraneous movement on the trajectory of a conducting path.…”

A Mechatronic System for the Visualisation and Analysis of Orchestral Conducting

This paper quantitatively analysed orchestral conducting patterns, and detected variations as a result of extraneous body movement during conducting, in the first experiment of its kind. A novel live conducting system featuring data capture, processing, and analysis was developed. Reliable data of an expert conductor's movements was collected, processed, and used to calculate average trajectories for different conducting techniques with various extraneous body movements; variations between extraneous body movement techniques and controlled technique were definitively determined in a novel quantitative analysis. A portable and affordable mechatronic system was created to capture and process live baton tip data, and was found to be accurate through calibration against a reliable reference. Experimental conducting field data was captured through the mechatronic system, and analysed against previously calculated average trajectories; the extraneous movement used during the field data capture was successfully identified by the system.
