The rates of reaction of methylene dibromide with alkali celluloses prepared from potassium hydroxide have been found to be more than double those with alkali cellulosed prepared from sodium hydroxide. The energies of activation in both cases are about 25 kcal./mole, statistically indistinguishable ...
Infestation rates of 30%–60% in sheep have been reported in the United States, Europe, Australia, and New Zealand. Prevalence of chorioptic mange tends to be highest in rams and generally low in ewes and lambs. Chorioptes bovis may spread by direct contact of the feet with other parts ...
“When we test the reading age of students, are they improving faster now, are rates of homework submission rising or falling, in terms of student wellbeing are they reporting they feel happier now then they did last year...all these metrics we can use to analyse whether it’s having a ...
Apoptosis was found to be associated with decreased rate of spermatogenesis. High apoptosis rates may result in azoospermia, which can occur despite normal spermatogenesis and absence of duct obstruction. 展开 关键词: spermatogenesis testis Mcl-1 expression immunohistochemical study infertility ...
Measurements are reported of rates of acid-catalyzed dehydration of water adducts (hydrates) of benzene, naphthalene, anthracene, and phenanthrene. Benzene hydrate (2,4-cyclohexadienol) reacts in aqueous acetic acid buffers and is subject to specific acid catalysis consistent with rate-determining for...

The Arrhenius model was applied to reaction rates (k) at each temperature and an activation energy (Ea) of 7.6 kcal.mol-1 and Q10 of = 2.0 was obtained. Shelf-life evaluation was based on subjective (Difference from Control Sensorial Discriminative Test) measurements over 4 months at 15 day...
The reaction stoichiometry for growth and PHA storage in ADF proposed for MMCs are shown in Table 6. Reactions R1-R11, as shown in Table 6, occur during the feast phase, while reactions R3 and R6-R11 are active during the famine phase (Dias et al., 2008; Jiang et al., 2011; Ren ...
Northern and northernmost populations showed the highest and growth rates. All populations expressed shorter and accelerated growth when raised in a northern compared with a central latitude photoperiod. The slopes of reaction norms differed between regions resulting in a region‐by‐photoperiod interaction...
(2 μl First-Strand Buffer, 0.25 μl 100 mM DTT, 1 μl 10 mM dNTP, 1 μl 12 mM SMARTer II A Oligonucleotide, 0.25 μl RNase inhibitor, and 1 μl SMARTScribeTM reverse transcriptase), the reaction was incubated at 42 °C for 90 ...
