We monitored the reproductive cycle of Strongylocentrotus droebachiensis (OF Müller) between April 1993 and August 1995 in kelp beds, barren grounds and grazing fronts at both a wave-exposed and a sheltered site along the Atlantic coast of Nova Scotia. Gonad index and histological analyses showe...
Another, holistic view on wave appearance in a given flux tube with several factors affecting the observed changes is also possible. Ionospheric ducting does not seem to be a significant factor in regulating long-term activity of high-latitude Pc1's. The data also suggests a nonlinear dependence...
Time swells like a wave at a wall and bursts to eternity —George Barker Time went on like an unchanging ribbon drawn across a turbulent background —Heinrich Boll Upon his silver hairs, time, like a Panama hat, sits at a tilt and smiles —Karl Shapiro In his poem, Boy-Man, Shapiro...
Sometimes we do not become adults until we suffer a good whacking loss, and our lives in a sense catch up with us and wash over us like a wave and everything goes —Richard Ford The art of life is more like the wrestler’s art than the dancer’s that it should stand ready and fi...
This paper focuses on the recent cycle of collective action across countries and continents over the past few years. It seems to be evident that in the outset of 2011 began a new wave of global protests made of contagion and communication that spread in different contexts. Our argument is tha...
Finally, this study culminates with a description of the reproductive cycle of B. undatum for the southern-most population in the range of this species in the Northwest Atlantic Ocean. To our knowledge, this is the first study to document the annual reproductive cycle of waved whelk in the ...
This case study will quantify the energy use, the carbon caused by Green House Gases and the sum of the costs for the entire life cycle (Life Cycle Assessment (LCA) and a Life Cycle Cost Analysis (LCCA)), using the WaveStar as the wave energy case study device. Life Cycle covers all...
The death of that star is the birth of a neutron star: 那个星体的死亡,成了一个中子星的诞生: one of the densest known objects in the universe, 中子星是全宇宙最高密度的已知物体之一, and a laboratory for the strange physics of supercondensed matter. ...
2. The duty cycle of the pulse train should be carefully adjusted to achieve the desired output.(脉冲列的占空比应该被精确调节以达到期望的输出。) 3. The duty cycle of the square wave is 50%, which means the high and low time periods are equal.(方波的占空比为50%,意味着高电平和低电平的...
Diurnal Cycle of Internal Wave Variability in the Equatorial Pacific Ocean: Results from Moored Observations A diurnal cycle in temperature and vertical displacement variance has been observed in the stratified region below the surface mixed layer using moored tim...
