The Role of Pragmatics in Cross-cultural
We here try to find out the role of pragmatics in the cross-cultural contexts. Pragmatics is the way we convey meaning through communication (Deda, 2013). Other factors beyond competence are the adjustments between contexts and situations that can change the ordinary meaning of elements/sentences according to the language situation. The culture of an organization decides the way employees behave amongst themselves as well as the people outside the organization. Pragmatic culture more emphasis is placed on the clients and the external parties. Customer satisfaction is the main motive of the employees in a pragmatic culture. In linguistics, pragmatic competence is the ability to use language effectively in a contextually appropriate fashion. Pragmatic competence is a fundamental aspect of a more general communicative competence

This study aims to determine the validity and the levels of mefenamic acid in tablet dosage using UV spectrophotometry and determine the suitability of levels tablet mefenamic acid with trade name and generic with the requirement levels according to the Indonesian Pharmacopoeia fourth edition (1995). Its validity were tested based on the parameters of accuracy used standard addition method and precision parameters. Based on the results the linearity value was obtain r = 0.9979 with limits of detection (LOD) is 0.1246 ppm and limits of quantitation (LOQ) is 0.4154 ppm. The results showed levels of mefenamic acid in tablet dosage trade name (1) is 11.3580 ± 0.6344 ppm, trade names (2) is 11.3044 ± 0.4147 ppm, generic (1) is 11.3044 ± 0, 5664 ppm, generic (2) was 11.604 ± 0.4180 ppm. It showed mefenamic acid levels in tablet dosage generic and trade names fulfill level requirements contained in the Indonesian Pharmacopoeia fourth edition (1995).

Electromagnetic mass splittings of the low lying hadrons and quark masses from 2+1 flavor lattice QCD+QED
Results are presented for the electromagnetic mass splittings of the low
lying hadrons.
These are used to determine the non-degenerate light quark masses.
It is found that m_u=2.24(10)(34), m_d=4.65(15)(32), and
MeV (MSbar scheme, 2 GeV scale). The first error is statistical and the second
systematic. We find the lowest order electromagnetic splitting
(m_pi+-m_pi0)_QED=3.38(23) MeV, the splittings including next-to-leading order,
(m_pi+-m_pi0)_QED=4.50(23) MeV, (m_K+-m_K0)_QED=1.87(10) MeV, and the m_u !=
m_d contribution to the kaon mass difference, (m_K+-m_K0)_(m_u-m_d)=-5.840(96)
MeV.
All errors are statistical only, and the next-to-leading order pion splitting
is only approximate; it does not contain all next-to-leading order
contributions. We also computed the proton-neutron mass difference, including
for the first time, QED interactions in a realistic 2+1 flavor calculation. We
find MeV, (m_p-m_n)_(m_u-m_d)=-2.51(14) MeV,
and the total m_p-m_n=-2.13(16)(70) MeV, where the first error is statistical,
and the second, part of the systematic error. We use domain wall fermions and
the Iwasaki gauge action (gauge coupling beta=2.13). We use two lattice sizes,
16^3 and 24^3, to address finite volume effects. Non-compact QED is treated in
the quenched approximation.
We present new results for the electromagnetic low energy constants in SU(3)
and SU(2) partially-quenched chiral perturbation theory to the next-to-leading
order, obtained from fits to our data.
Detailed analysis of systematic errors in our results and methods for
improving them are discussed. Finally, new analytic results for SU(2)_L x
SU(2)_R-plus-kaon chiral perturbation theory, including the one-loop logs
proportional to alpha_em*m, are given.Comment: Significant additions: finite volume analysis of kaon mass (Sec. II
and the Appendix) which is used to obtain new central values, extended
discussion of the breaking of Dashen's theorem (VII), additional
phenomenological results (VII), and a new section (VIII) on isospin breaking
effects on the kaon decay constant. No conclusions or results from the first
version changed significantl
The X-ray Spectrum and Light Curve of Supernova 1995N
We report on multi-epoch X-ray observations of the Type IIn (narrow emission
line) supernova SN 1995N with the ROSAT and ASCA satellites. The January 1998
ASCA X-ray spectrum is well fitted by a thermal bremsstrahlung (kT~10 keV,
N_H~6e20 cm^-2) or power-law (alpha~1.7, N_H~1e21 cm^-2) model. The X-ray light
curve shows evidence for significant flux evolution between August 1996 and
January 1998: the count rate from the source decreased by 30% between our
August 1996 and August 1997 ROSAT observations, and the X-ray luminosity most
likely increased by a factor of ~2 between our August 1997 ROSAT and January
1998 ASCA observations, although evolution of the spectral shape over this
interval is not ruled out. The high X-ray luminosity, L_X~1e41 erg/sec, places
SN 1995N in a small group of Type IIn supernovae with strong circumstellar
interaction, and the evolving X-ray luminosity suggests that the circumstellar
medium is distributed inhomogeneously.Comment: MNRAS accepted. 6 pages, 2 figures; uses mn.sty and psfi
