To address the logical incoherence issue related to existing design models, this paper employs the conceptual foundation developed before to establish a new process model of conceptual design, i.e., the Need-Function-Principle-System model, which elaborates a conceptual design process with five major stages, i.e., clarification, synthesis, embodiment, analysis and prediction.
In most phages, head assembly involves five major stages, each involving a number of phage encoded proteins.
Early development of lateral roots, which may recapitulate embryonic and primary root formation, can be separated into five major stages: initiation, establishment and emergence of lateral root primordia, followed by meristem activation and maintenance (Malamy and Benfey, 1997).
Similarly, Rogers and Quatrano [ 4]divided wheat grain development into five major stages, from I to V. Based on their observations, the 40 to 80°Cdays stage in the present study corresponded to stage I, during which fertilization and a coenocytic endosperm occur.
Prochaska and colleagues' Stages of Change Model [ 46] describe a spiral pattern of behavioural change comprising of five major stages; precontemplation, contemplation, preparation, action and maintenance with those who are in the early stages being either unaware, in denial or not able to commit to making any changes.
To study PABCs in vivo, we utilized a model we previously described [ 36] in which carcinoma cells are introduced directly into the fourth inguinal mammary glands of mice at the five major stages of postnatal development: post-pubertal (nulliparous), pregnancy, lactation, involution and upon full regression of the gland following involution.
Kruglanski conceptualizes our need for cognitive closure as consisting of two major stages, seizing and freezing.
Fruit development can generally be divided into three major stages: growth, maturation, and senescence.
Two major stages -- the Metaxourgeio Theater and the experimental stage of Greece's national theater -- are across the street from each other, regularly attracting cultured older Athenians.
In addition, both leaders of England's two major stages – Nicholas Hytner at the National Theatre and Gregory Doran at the Royal Shakespeare Company – have never, over the course of their careers, directed a play by a woman.
