“…However, we did locate evidence of an embryonic neural process that organizes midline cranial features, which could plausibly relate morphology to behavior in other contexts. It is possible that a prominent tubercle of the lip is a marker of more complete development (it is also possible that in some cases a prominent tubercle of the lip is because of retention, as opposed to infantile loss, of the tubercle [29], which some have conjectured aids the infant's suckling [30]). Thus, it is possible that a flatter or absent tubercle might have something in common with the at times subtle lip abnormalities associated with subtle neuropsychologic abnormalities in marginal cases of fetal alcohol syndrome [31,32].…”

Introduction Recent studies have uncovered multiple markers of vaginal orgasm history (unblocked pelvic movement during walking, less use of immature psychological defense mechanisms, greater urethrovaginal space). Other markers (perhaps of prenatal origin) even without obvious mechanistic roles in vaginal orgasm might exist, and a clinical observation led to the novel hypothesis that a prominent tubercle of the upper lip is such a marker. Aims To examine the hypothesis that a prominent tubercle of the upper lip is associated specifically with greater likelihood of experiencing vaginal orgasm (orgasm elicited by penile–vaginal intercourse [PVI] without concurrent masturbation). Methods Women (N = 258, predominantly Scottish) completed an online survey reporting their frequencies of various sexual activities and corresponding orgasms, age, and the prominence of the tubercle of their upper lip. Social desirability response bias was also assessed. Main Outcome Measures Multivariate associations of lip tubercle prominence with vaginal orgasm (ever and past month consistency) and with orgasm by other means. Results A prominent and sharply raised lip tubercle was associated with greater odds (odds ratio = 12.3) of ever having a vaginal orgasm, and also with greater past month vaginal orgasm consistency (an effect driven by the women who never had a vaginal orgasm), than less prominent lip tubercle categories. Lip tubercle was not associated with social desirability responding, or with orgasm triggered by masturbation during PVI, solitary or partner clitoral or vaginal masturbation, vibrator, or cunnilingus. Conclusions The results are discussed in light of the unique nature of vaginal orgasm and the possibility of prenatal developmental influences.

“…ethers) structures was studied 25, 26. The determination of the epoxide conversion in glycidyl ethers is based on changes of the intense band at 2 205 nm, which is assigned to a combination of the CH stretching fundamental at 3 050 cm −1 with the CH 2 deformation band at 1 460 cm −1 ,31 or on the first and the second overtone of the mentioned stretching vibration at 1 650 and 1 159 nm, respectively 32…”

Coatings from blends of cycloaliphatic epoxides and vinyl ethers were cross‐linked by UV‐induced cationic photopolymerization. The conversion of the vinyl double bonds during postcuring was followed by NIR reflection spectroscopy. The effect of various parameters such as the composition of the reactive formulation or the applied radiation dose on the kinetics of the postcuring process was studied. Finally, it was demonstrated on a pilot‐scale curing line that NIR spectroscopy can be used for inline monitoring of the actual conversion in UV‐cured coatings from cationic photopolymers.magnified image

“…This peak is probably a combination of the C-H stretching fundamental ( v CH = 3050 cm-1 ) with the CH 2 deformation fundamental (6 CH 2 = 1460 cm -1 ) of the oxyrane ring and is less sensitive to hydrogen bonding than are the amine combination (and probably overtone) bands. As underlined by Dannenberg [11,14], determination of the epoxy content of cured epoxy by infrared includes the assumption that the absorbance is constant regardless of the degree of eure (from liquid to solid state) and that there is no deviation from Beer's law. The Iack of calibration standards for cross-linked resins complicates the determination of all functional groups in the cured epoxy resins.…”

Abstract. In recent years NIR spectroscopy has been successfully used to study the kinetic reactions of cross-linked resins. Since the roJe played by hydrogen bonding strongly influences the chemical, physical and mechanical properlies of polymers containing hydroxyl, urethane, amine or amide functional groups, it is not surprising that the change ofhydrogen bonding during the eure can modify the absorptivity of chemical groups under investigation (up to 10% for the NH 2 combination band in a solvent amine blend) and can Iead to inaccurate infrared quantitative analysis. More care should be taken in the choice of the reference band to monitor the reaction eure.
