Experimental Study on Enhanced Methane Detection Using an MEMS-Pyroelectric Sensor Integrated with a Wavelet Algorithm.

An optical sensing approach that balances portability with cost efficiency has been designed for the reliable monitoring of fugitive methane (CH) emissions. Employing a LiTaO-based pyroelectric detector integrated with micro-electro-mechanical systems and a broad infrared source, the developed gas sensor adeptly measured CH concentrations with a low limit of detection of about 5.6 ppm and showed rapid response times with consistently under 3 s.

On Improving Water-Based Drilling Mud Swelling Control Using Modified Poly(Vinyl Alcohol)s.

One of the most challenging issues when drilling under high-temperature, high-pressure (HT/HP) conditions is wellbore instability caused by clay swelling and fluid loss of the drilling mud. One of the most difficult issues when drilling under high-temperature, high-pressure (HT/HP) conditions is wellbore instability caused by clay swelling and fluid loss in drilling mud. Two modified PVOHs, nonionic and cationic polymers made from sodium bentonite clay and deionized water at concentrations of 0.

Social Networks' Health Habits Over Life Course and Late-life Health Habits.

In this study, we examined Japanese older adults' health habits (healthy diet, exercise, and nonsmoking) using 4 models: sensitive period, pathway, social mobility, and cumulative effects. A representative cross-sectional survey of people 65 years and older, living in Tokyo, produced 739 effective respondents. Health habits in social networks over the life course, at junior high school, age 20, and age 40, were measured through retrospective recall questions.

Time perspectives as mediators of the associations between socio-economic status and health behaviours in older Japanese adults.

Few studies have used time perspective (TP) theory to examine the factors mediating the association between socio-economic status (SES) and health behaviours (i.e. the psychological mechanisms that underlie SES differences in health behaviours).

A positive attitude towards provision of end-of-life care may protect against burnout: Burnout and religion in a super-aging society.

Aim: The aim of our study was to investigate factors associated with burnout of nurses and care workers in nursing homes and geriatric hospitals in Japan. The use of Buddhist priests, the major religion in Japan, was also explored.

Methods: Questionnaires for nurses and care workers were sent to 10 care facilities.
