Because sleep comprises one-third of a person's life, using an optimal pillow for appropriate neck support to maintain cervical curve may contribute to improve quality of sleep. Design of orthopedic pillow conforms to orthopedic guidelines to ensure the right support of the cervical curve. The aim of this study was to investigate effect of different pillow shape and content on cervical curve, p...

A random allocation single blind block design pillow field study was undertaken to investigate the behaviour of cervico-thoracic spine pain in relation to pillow use. Participants (N=106) who reported preference for side sleep position with one pillow were recruited via a telephone survey and newspaper advertisement. They recorded sleep quality and pillow comfort ratings, frequency of retiring ...

The interaction between volcanic processes and glacial ice is termed glaciovolcanism a process that prevalent on Earth potentially once Mars. Such are dynamic, forming habitable environments under ice. This work will attempt to describe the glaciovolcanic deposits at Crazy Hills Lone Butte in central Washington evaluate potential habitability of these glaciovolcanoes. identification pillow lava...

It is widely believed that using a pillow that allows appropriate neck support to maintain cervical lordosis during sleep can lead to better quality sleep.Conversely, use of the wrong type of pillow can compromise pain-sensitive structures and produce waking symptoms, such as cervical pain and stiffness, headaches, and arm pain; and this in turn results in reduced sleep quality. Therefore, the ...

Sleep quality is an essential factor to human beings for health. The current paper conducted four studies to provide a suitable pillow for promoting sleep quality. Study 1 investigated the natural positions of 40 subjects during sleep to derive key-points for a pillow design. The results suggested that the supine and lateral positions were alternatively 24 times a night, and the current pillows...

This paper reports the first discovery of basic igneous rocks in Bairin Right Banner southeastern Inner Mongolia, China. To understand genesis and tectonic evolution these rocks, we have carried out geochronology geochemistry research on them. The results show that LA-ICP-MS zircon U-Pb concordant mean ages massive basalt, diabase, pillow basalt are 272.0 ± 2.8 Ma, 261.5 3.2 256.5 2.5 respectiv...

BACKGROUND Cervical pillow height is an important factor that affects the perception of pillow comfort. However, few studies have addressed methods for predicting a patient's preferred cervical pillow size. We studied the effect of pillow size preference on the strength and electromyographic (EMG) signals of the upper extremity muscle. If the response of the upper extremity muscle is affected b...

BACKGROUND Pillows are intended to support the head and neck in a neutral position to minimize biomechanical stresses on cervical structures whilst sleeping. Biomechanical stresses are associated with waking cervical symptoms. This paper adds to the scant body of research investigating whether different pillow types produce different types and frequencies of waking symptoms in asymptomatic subj...

A critical element in the construction of tectonic models exhumation basalts that have undergone high-pressure metamorphism is diagnosis synchronicity and genetic relationship between deformations metamorphic changes. In this report, these issues are discussed on example metabasalts Chara ophiolite belt. bottom basalt block with separation pillow lavas near Burshabulak farm, crack-vein systems ...
