Fertile period

In order to avoid conception, abstinence from sexual intercourse during the fertile period of the menstmal cycle must be practiced (77,104). It has been deterrnined that the fertile period in women occurs before menstmation (105,106), and formulas have been developed to determine the fertile and infertile days of the menstmal cycle. Ovulation has been linked to a cycHc shift in basal body temperature (107), which can be used retrospectively to determine the time of ovulation. 

Most recently, Havlicek, Bartos, Dvorakova and Flegr (2006) tested women s body odour repeatedly across the whole menstrual cycle and focused specifically on axillary scents. Male subjects rated the smell of the samples as least attractive during menstrual bleeding and most attractive during the follicular (i.e. fertile) period of the cycle.

Another variant on hormone replacement therapy involves using aU three types of sex steroid in parallel, starting from the argument that during the fertile period all three are sjmthesized by the ovary (7). A natural version of this therapy uses estradiol, testosterone (with or without dehydroepiandrosterone), and progesterone in an appropriate pharmaceutical form (for example micro-nized), so that absorption is attained without the need for 17-substitution. This approach naturally avoids some of the undesirable effects of the synthetic steroids, and has been stated to improve menopausal depression and anxiety. However, the adverse effects of all three types of component can be experienced. 

We have compared the birth of quantum theory to a drama written and acted by Planck, Einstein, Bohr, and de Broglie. Indeed they inherited a critical mind with a deep insight into the quantum theory and they pursued continuously the development of this concept. From their research in that fertile period of time, we can study the inner workings of their considerations as human beings. Taking advantage of the failure of classical mechanics, they created a new concept. In the formation process of the quantum theory, they never denied the system of classical physics. The new physical system which they constructed included classical physics and grew to such a scale that it exerted a tremendous influence upon all science fields for nearly a century. 

Female-based constraints include physiological and anatomical aspects. Temporally, the estrous cycle of female elephants is long (16—18 weeks), yet the fertile period is short... 

As the Bond Legacy entered the 90s, small studio productions of the various novels and short stories popped up like mushrooms after rain. A host of production companies, directors, and actors hied through the Bond turnstile, handing out more and more outre interpretations. The nostalgia for the Cold War, perverse as it seemed, offered a fertile period for the last of the superspies. The wear and tear on the originak began to show by the turn of the century, and if new Bond adventures were to be hlmed they would necessarily have to be based on new material. 

The past three years have been a partieularly fertile period for the advancement of SPM imaging techniques. Gross et al. s demonstration that not only atoms but single bonds could be resolved inside an adsorbed molecule (see Section 4) prompted a number of researeh groups to adopt the IBM Zurich group s experimental protocols (particularly with regard to tip functionalization) in order to enable and enhance new imaging and spectroscopic measurements. Fig. 1 puts these recent advances in the context of the broader history of SPM.
