In order to provide a consistent explanation for Aristotelian modal syllogistic, this paper reveals the reductions between syllogism ◇I□A◇I-3 and other valid syllogisms. Specifically, on basis of formalizing syllogisms, proves validity by means truth value definition (modal) categorical propositions. Then in line with classical propositional logic logic, generalized quantifier theory set theory...

Abstract. The direct vapor equilibration laser spectrometry (DVE-LS) method has been developed for obtaining matrix-bound water stable isotope data in soils, the critical zone, and bedrock, deriving therefrom subsurface flow transport processes and, ultimately, characterizing, example, groundwater recharge vulnerability. Recently, DVE-LS increasingly adopted due to its possible high sample thro...

Laboratory and field experiments were performed to evaluate the pathogenicity of an isolate entomopathogenic fungus Metarhizium anisopliae two sympatrically occurring weevil species, Cylas formicarius Euscepes postfasciatus. In laboratory bioassays, suspension conidia, ≥106 CFU/mL, caused mortalities > 80% on adults both weevils in seven days after inoculation. It took longer time 20 for grain ...

The roles of cyclic AMP and cyclic AMP-dependent protein kinase in the contractile and metabolic responses to neural stimulation were studied in the bullfrog heart perfused in situ. The interaction of parasympathetic and sympathetic nerves in the regulation of myocardial cyclic AMP, cyclic AMP-dependent protein kinase, and phosphorylase also was studied. Stimulation of the left vagosympathetic ...

Using AMP deaminase (AMP aminohydrolase; EC 3.5.4.6) purified from rabbit left-ventricular heart tissue, we report direct investigation of the potential for cardiac AMP deaminase activity to be regulated by kinase-mediated phosphorylation. Rabbit heart AMP deaminase served as a substrate for Ca2+/phospholipid-dependent protein kinase (protein kinase C; PKC) exclusively; no other mammalian prote...

An extract of royal jelly (RJ) induced processes from cultured rat pheochromocytoma PC12 cells. Active components were isolated, and identified as adenosine monophosphate (AMP) and AMP N1-oxide. AMP N1-oxide was more than 20 times as active as AMP, judging from the minimal concentration to elicit activity. AMP N1-oxide was thought to be responsible for about half of the process-forming activity...

Periodic activities of Dictyostelium discoideum cells involve two types of oscillations, spike-shaped and sinusoidal. Spike-shaped oscillations are accompanied by the periodic synthesis and release of cyclic AMP, and cyclic AMP-activated cyclic AMP synthesis is believed to control these oscillations. Experiments described here call into question the importance of cyclic AMP in spike-shaped osci...

1. The present study extends the finding of Krebs & Woodford (1965) that muscle fructose diphosphatase is more sensitive to AMP inhibition than liver fructose diphosphatase. 2. Hen breast fructose diphosphatase has a K(i) for AMP of 0.1mum; the plot of percentage inhibition is non-sigmoid and the reciprocal plot of activity against AMP concentration is sometimes linear. 3. Percentage inhibition...

Monsters are commonly stereotyped as horrible and grotesque creatures. But in Frankenstein The Island of Doctor Moreau, Shelly Wells both delineate some complicated but meaningful monster characters. These monsters’ features natures represent their creator’s intention purpose. In texts, monsters ugly benevolent, while creators eccentric monstrous. relationship between men allows us to view the ...
