This paper [1] introduces ARQuake, a modification of id Software’s first-person shooter, Quake. Equipped with a head-mounted display and GPStracked laptop backpack, ARQuake players can move across the University of South Australia campus, shooting monsters as they go. ARQuake is particularly relevant to this project as it was one of the first serious attempts to create a mixed reality computer ...

The paper proposes a model of an ecological backpack, which corresponds to the interpretation Friedrich Schmidt-Blick, for Ukrainian coal at stage its extraction. environmental backpack is included in concept MIpS (Material input per unit service). It that has been adopted as response function “grey” cybernetic box symbolises national mine fund. factors determine are biotic and abiotic material...

The objective of this study was to evaluate different strategies for the application of entomopathogenic nematodes (EPN). Three different models of spray nozzles with air induction (AI 11003, TTI 11003 and AD-IA 11004), three spray pressures (207, 413 and 720 kPa), four different additives for tank mixtures (cane molasses, mineral oil, vegetable oil and glycerin) and the influence of tank mixtu...

Natural systems retain significant advantages over engineered systems in many aspects, including size and versatility. In this research, we develop a hybrid robotic system using American (Periplaneta americana) and discoid (Blaberus discoidalis) cockroaches that uses the natural locomotion and robustness of the insect. A tethered control system was firstly characterized using American cockroach...

Backpacks are common devices that enable people to increase their load carriage capabilities, not only in military missions but also in civilian activities. When heavily loaded, some inadequate load-carriage systems may lead to excessive fatigue or even impair the user. The purpose of the study described here is to increase the understanding of dynamic backpack behaviour and its impact on the u...

ORTHOPEDICS | www.orthobluejournal.com Back pain is an epidemic in the adult population with 60% of adults reporting having experienced back pain.1-3 Back symptoms are the second leading symptomatic reason expressed by patients in the United States for consulting physicians.4 The incidence of back pain in children and adolescents varies from 8%-84.1%.5-15 The reported incidence depends on the p...

Load Carriage using backpacks is an occupational task and can be a recreational pursuit. The aim of this study was to investigate the mechanisms responsible for changes in neuromuscular function of the m. quadriceps femoris following load carriage. The physiological responses of 10 male participants to voluntary and electrically stimulated isometric contractions were measured before and immedia...
