: In this work, different levels of theory containing HF, B3LYP, and MP2 with different basis sets such as 6-31G, 6-31G*, 6-311G, 6-311+G, 6-31+G*, 6-31+G are used to predict relative acidity constants of some aniline derivatives. Three different kinds of radii containing UAHF, Bondi, and Pauling are used to study how cavity forms change acidity constants. In all cases, DPCM model is used to si...

Resolving community noise problems demands not just accurate data about noise impacts but also requires an effective means of communicating this information to decision makers. The Interactive Sound Information System (ISIS) is a “new media” package designed to explain and de-mystify the complex metrics used to describe noise impacts. Central to the ISIS package is the idea that “real” noise ex...

After 10 years of follow-up of a cohort of adolescents and young adults living in Munich, Tijssen et al (pp. 102–108) found that the persistence of affective symptoms earlier in life predicted later development of bipolar disorder in a dose–response fashion. They confirmed that although hypomanic symptoms are relatively common in adolescence, most resolve with time. In a Swedish national cohort...

We investigate the Peterson hit problem for polynomial algebra \(\mathcal P_{d}\), viewed as a graded left module over mod-\(2\) Steenrod algebra, \(\mathcal{A}\). For \(d>4\), this is still unsolved, even in case of \(d=5\) with help computers. In article, we study \(d=6\) generic degree \(6(2^{r}-1)+6.2^r\), \(r\) an arbitrary non-negative integer. Furthermore, behavior sixth Singer algebraic...
