The present article reports the application of hexamethylsilazane (HMDS) modified filter paper for ultrasensitive detection of Hg(2+), Co(2+) and Zn(2+). By chemical vapor deposition of HMDS, a highly hydrophilic filter paper was fabricated to a low wetting (hydrophobic) substrate. The water contact angle (θ) of modified paper was ∼128°, whereas scanning electron and atomic force microscopy con...

Graphene-based devices show good transfer characteristics, which depend upon the surface morphology of material and substrate. During fabrication device, substrate is disturbed inappropriately by contamination. In present study, monolayer Graphene Field Effect Transistor (GFET) has been driven with hydrophobic Hexamethyl Disilazane (HMDS) layer. The HMDS layer dehydrated before after exfoliated...

Head-mounted displays (HMDs) for augmented reality (AR) have received much scholarly attention. Most studies on AR HMDs, however, rely lab-based environments or simplistic tasks that do not reflect the complexity of industrial work processes. In this work, we conducted a field study in which professional machine operators performed setup task an injection molding machine. We assessed and compar...

Many users have shown increased postural instability while using Head-Mounted Displays (HMDs) as HMDs block their real-world vision. People with balance impairments are especially more affected by this they depend on visual cues to maintain balance. In addition, is a good indication of cybersickness according theory. research, we investigated how use additional improve stability. Through conduc...

Current head-mounted displays (HMDs) provide only a fixed lens focus. Viewers have to decouple their accommodation and vergence responses when viewing stereoscopic images presented on an HMD. This study investigates the time taken to fuse a pair of stereoscopic images displayed on an HMD when the accommodative demand is matched to the vergence demand. Four testing conditions exhausting the fact...

In this paper, we apply a comprehensive approach to evaluate and analyze potential physiological and subjective workload effects of the application of head-mounted displays (HMDs) during a typical 3.5 hrs assembly operation. The approach refers to physical as well as cognitive workload associated with HMDs. The methods for capturing and determining physiological workload include an analysis of ...

Technological advances in helmet-mounted displays (HMDs) have permitted the design of “see-through” displays in which virtual imagery may be superimposed upon real visual environments. The utility of see-through displays in multitask environments remains uncertain, especially in environments that involve switching one’s attention between those tasks represented in the virtual display and those ...

The low yield potential of most biofortified maize is a barrier to its full adoption and reduces curb various macro- micronutrient deficiencies highly prevalent in low-income regions the world, such as sub-Saharan Africa (SSA). By crossing inbred lines with different nutritional attributes zinc (Zn), provitamin A protein quality, breeders are attempting develop agronomically superior stable mul...
