The Impact of Airflow and Multisensory Feedback on Immersion and Cybersickness in a VR Surfing Simulation.

Virtual Reality (VR) systems have increasingly leveraged multisensory feedback to enrich user experience and mitigate cybersickness. With a similar goal in focus, this paper presents an in-depth exploration of integrating airflow with visual and kinesthetic cues in a VR surfing simulation. Utilizing a custom-designed airflow system and a physical surfboard mounted on a 6-Degree of Freedom (DoF) motion platform, we present two studies that evaluate the effect of the different feedback modalities.

Understanding the Enzymatic Synthesis of a New Biolubricant: Decane-1,10-diyl bis(2-methylpentanoate).

The value of branched esters comes from the special properties they have in cold environments, which allow them to remain liquid over a wide range of temperatures. These properties make them useful for application in the cosmetic industry or as lubricant additives. This paper presents the studies carried out to ascertain the operational feasibility of the enzymatic esterification of 2-methylpentanoic acid (MPA) with 1,10-decanediol (DD), with the objective of obtaining a novel molecule: decane-1,10-diyl bis(2-methylpentanoate) (DDBMP).

Comparison of Sulfamethoxazole Removal Efficiency Using Polyethersulfone Ultrafiltration Membrane Modified by Various Methods.

Nowadays, there is a growing interest in membrane modification processes to improve their characteristics and the effectiveness of their treatments and reduce the possible fouling. In this sense, in this work, a modification of an ultrafiltration membrane with three different materials has been carried out: reduced graphene oxide (rGO), chitosan and MgCl. For both the native and the modified membranes, a study has been carried out to remove the emerging contaminant sulfamethoxazole (SMX).
