چکیده

" Sentential reflection " in the sense of [Fr03] is based on reflecting down from a category of classes. " Elemental sentential reflection " is based on reflecting down from a category of elemental classes. We present various forms of elemental sentential reflection, which are shown to interpret and be interpretable in certain set theories with large cardinal axioms.

On Two Notions concerning the Structural Sentential Calculi

For any structural sentential calculus (L,C) and sentential language L, similar to L, we put Θo C = {C ′|C ′ is a structural consequence operation on Lo satisfying: A ∈ C(X) only if eA ∈ C ′(eX), all X ∪ {A} ⊆ L and e ∈ Hom(L,Lo)}. Let us recall the following Definition (R. Wójciciki, see III §in [4]). Let (L,C) be structural and Lo be a sentential language similar to L. The projection of (L,C)...

An RXTE Observation of the Seyfert 1 Galaxy MCG − 6 - 30 - 15 : X - ray Reflection and the Iron Abundance

We report on a 50 ks observation of the bright Seyfert 1 galaxy MCG−6-30-15 with the Rossi X-ray Timing Explorer. The data clearly show the broad fluorescent iron line (equivalent width ∼ 250 eV), and the Compton reflection continuum at higher energies. A comparison of the iron line and the reflection continuum has enabled us to constrain reflective fraction and the elemental abundances in the ...

The Effect of Intra-sentential, Inter-sentential and Tag- sentential Switching on Teaching Grammar

The present study examined the comparative effect of different types of code-switching, i.e., intrasentential,inter-sentential, and tag-sentential switching on EFL learners grammar learning andteaching. To this end, a sample of 60 Iranian female and male students in two different institutionsin Qazvin was selected. They were assigned to four groups. Each group was randomly assigned toone of the...

Application of total reflection X-ray fluorescence spectrometry to small glass fragments.

Total reflection X-ray fluorescence spectrometry (TXRF) has been applied for trace elemental analysis of small glass fragments. A small glass sample (a fragment with weight less than 0.5 mg) was decomposed by 100 microg of HF/HNO3 acid; the material was condensed to 10 microl and was dried on a Si wafer. Since the size of the dried residue on the Si wafer was less than 1 cm in diameter, an inci...

Optical Properties of Fine Particulate Matter in Upper Silesia, Poland

Ambient particles whose aerodynamic diameters were not greater than 2.5 μm (fine fraction of Particulate Matter; PM2.5) and 1 μm (PM1; sub-fraction of PM2.5) were sampled at three sites in Upper Silesia (Poland): urban background site, rural background site, and urban traffic site. In total, 240 samples were collected between 2 August 2009 and 27 December 2010. The reflectance of the collected ...
