I recently became sexually active at 21, and my partner is a bit older and has had multiple partners. At this point, we are exclusive, and have used a condom on the few occasions we have had intercourse. I went to the local Planned Parenthood recently, and am now on a birth control pill (I am absolutely sure I don't want or need to be pregnant at this point or ever in my life, personal choice.....

Catalases are ubiquitous hydrogen peroxide-detoxifying enzymes. They participate in fungal growth and development, such as mycelial growth and cellular differentiation, and in protecting fungi from oxidative damage under stressful conditions. To investigate the potential functions of catalases in Pleurotus ostreatus, we obtained two catalase genes from a draft genome sequence of P. ostreatus, a...

The position of diierent kinds of CP stars of the upper Main Sequence (i.e. Am stars and the four categories of Ap stars: He-weak, HgMn, Si and SrCrEu) in the HR diagram is examined. Using only those stars having a parallax with a relative error smaller than 0.14 ((M v) 0:3) and an absolutely certain peculiarity, it is shown that their absolute magnitudes are similar to those obtained from CP s...

In What is Philosophy? the distinguished philosopher Dietrich von Hildebrand analyses the datum of knowledge itself in its different forms, from the most casual perception of some object in our naïve experience to "a priori knowledge," taken as consisting of absolutely certain insights into "necessary essences." Plato's central teaching about that kind of human knowledge which transcends the wo...

In 2001, S. Bulman-Fleming et al. initiated the study of three flatness properties (weakly kernel flat, principally weakly kernel flat, translation kernel flat) of right acts $A_{S}$ over a monoid $S$ that can be described by means of when the functor $A_{S} otimes -$ preserves pullbacks. In this paper, we extend these results to $S$-posets and present equivalent descriptions of weakly kernel p...

The myelin Po protein is believed to hold myelin together via interactions of both its extracellular and cytoplasmic domains. We have already shown that the extracellular domains of Po can interact in a homophilic manner (Filbin, M.T., F.S. Walsh, B.D. Trapp, J.A. Pizzey, and G.I. Tennekoon. 1990. Nature (Lond.). 344:871-872). In addition, we have shown that for this homophilic adhesion to take...
