Employing the Peltier Effect to Control Motor Operating Temperatures

Energies, 2023
Electrical insulation failure is the most common failure mechanism in electrical machines (motors and generators). High temperatures and/or temperature gradients (HTTG) are the main drivers of insulation failure in electrical machines.

Monitoring of Cardiorespiratory Signal: Principles of Remote Measurements and Review of Methods

IEEE Access, 2017
Physiological signs can be remotely observed from the physiological and physical effects caused by a cardiorespiratory activity. A wide range of research on remote cardiorespiratory monitoring systems has been done using different methods, including ...

Hand-in-Air (HiA) and Hand-on-Target (HoT) Style Gesture Cues for Mixed Reality Collaboration

IEEE Access, 2020
In collaboration systems, collaborators often use hand gestures for showing information relating to a distant object. However, in viewer's perspective, it is sometimes difficult to know where the conventional gesture cue (Hands-in-Air style: HiA) refers ...

Plant responses to nitrate and ammonium availability in Australian soils as measured by diffusive gradients in thin-films (DGT) and KCl extraction

Geoderma
Determining soil nitrogen (N) availability is essential in agriculture to minimise over-application, maximise growers’ returns and reduce potential environmental consequences. The present study assesses soil mineral N (nitrate-N and ammonium-N) using the

Review of avian influenza outbreaks in Nigeria 2006–2025

Open Veterinary Journal
Avian influenza (AI), particularly highly pathogenic avian influenza (HPAI) subtype H5N1, emerged as a significant global threat in the mid-2000s, causing widespread outbreaks in poultry and sporadic human infections.

Soil communities following harvest have different early successional dynamics compared with post-wildfire patterns

Scientific Reports
Stand-replacing wildfire is the primary natural disturbance in jack pine-dominated boreal forests; but clearcut harvest also emulates this natural renewal process.

Under vaccination of children among Maasai nomadic pastoralists in Kenya: is the issue geographic mobility, social demographics or missed opportunities?

BMC Public Health, 2018
Background Nomadic lifestyle has been shown to be a significant factor in low immunization coverage. However, other factors which might aggravate vaccination uptake in nomadic pastoralists are poorly understood.
