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 ...

Figure 1. Relief map of island of Hawaii (after Moore et al., 1995) showing locations of dive sites (triangles, except dive 389, which is a square), locations of shield volcanoes (L—Loihi, K—Kilauea, ML— Mauna Loa, H—Hualalai, MK—Mauna Kea, Ko—Kohala), areas of recent Kilauea eruptions along south coast of Hawaii (u—Mauna Ulu, p—Puu Oo), rift zones of Mauna Loa (parallel lines), large, ca. 100 ...

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...

We report new petrographic and geochemical observations on magmatic sulfides occurring in different enclave types, including hornblende and/or clinopyroxene-rich cumulates, the host lavas, Nisyros (South Aegean volcanic arc). discuss our findings context of pre-existing petrological thermobarometry studies. Our results indicate that become less abundant Cu-richer (Cu median values) with magma d...

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...

[1] The radiogenic isotopic ratios of Sr, Nd, Hf, and Pb in basaltic lavas associated with major hot spots, such as Hawaii, document the geochemical heterogeneity of their mantle source. What processes created such heterogeneity? For Hawaiian lavas there has been extensive discussion of geochemically enriched source components, but relatively little attention has been given to the origin of dep...

Ferric/ferrous ratios have been used to estimate the oxygen fugacity of lavas erupted in 1984 on Mauna Loa Volcano, Hawaii. Rapidly quenched lavas erupted close to vents are less oxidized than rapidly quenched lavas scooped from lava flows several kilometers away from the vents. These results demonstrate that sampling is of critical importance in determining the oxidation state of lava. The oxi...
