Abstract This paper examines Nathaniel Hawthorne’s ecophilosophy in “Rappaccini’s Daughter” by focusing on his various representations of the natural environment and human relationship to it. It suggests that story reflects belief nature is divinely arranged humanity should protect rather than manipulate its systems. From perspective, disruption systems would not only cause extinction many anim...

The Space Tethered Autonomous Robotic Satellite (STARS) is being developed in Kagawa University and it will be launched by the H-IIA rocket by Japan Aerospace Exploration Agency (JAXA) in summer 2007. The main purpose of the STARS is technical verification for a tethered space robot proposed in 1995. The STARS consists of mother and daughter satellites connected by tether. The mother satellite ...

The two centrioles of the centrosome differ in age and function. Although the mother centriole mediates most centrosome-dependent processes, the role of the daughter remains poorly understood. A recent study has implicated the daughter centriole in centriole amplification in multiciliated cells, but its contribution to primary ciliogenesis is unclear. We found that manipulations that prevent da...

Centriole duplication occurs once per cell cycle, ensuring that each cell contains two centrosomes, each containing a mother-daughter pair of tightly engaged centrioles at mitotic entry. Loss of the tight engagement between mother and daughter centrioles appears to license the next round of centriole duplication. However, the molecular mechanisms regulating this process remain largely unknown. ...

Primer T he growth and development of all eukaryotes depends on the process of asymmetric cell division, in which a single cell gives rise to two genetically identical cells that adopt distinct fates [1,2]. Asymmetry occurs when two cells are exposed to different environmental stimuli or when specific mRNAs or proteins (known as cell fate determinants) are segregated unequally. In recent years,...

this article studies sir walter scott’s use of the family-as-nation trope in ivanhoe and anne of geierstein. the importance of this trope in his figuration of nationhood is discerned by carrying out a close reading of the texts and placing them in their historical context, which primarily consists of a comparison with edmund burke and maria edgeworth. consequently, his position is revealed as b...
