Killing terrorists : a moral and legal analysis
Get PDFTargeted killing of terrorists has become an established practice in the fight against terrorism. The disturbing consequences of the practice and its increasing political and societal acceptance raise questions as to its justifiability and its place in counter-terrorism. Anna Goppel explores whether targeted killing of terrorists can be justified, both from a moral and an international legal perspective. She discusses moral and international legal limits to state use of lethal force and argues that the moral principles and the international legal regulations allow for the practice only in very specific, very rare, and rather hypothetical cases. The analysis is based on a thorough discussion of the human right to life, the laws and ethics of war, and the relevant moral and legal arguments. This makes it of particular interest to philosophers and legal theorists interested in terrorism, counter-terrorism, human rights, and the legitimacy of defensive state measures
Evaluation of Heart-Rate Turbulence as a risk predictor after acute myocardial infarction in a gender specific manner
No full textUntersucht wurde, ob die diagnostische Wertigkeit der Heart-Rate Turbulence (HRT) bei der Prädiktion der Gesamtmortalität nach Myokardinfarkt geschlechtsspezifische Unterschiede zeigt. Die Studienpopulation waren 1657 konsekutive Infarktpatienten (24% Frauen, 76% Männer). Die Qualität der Risikoprädiktion wurde anhand von ROC Kurven für verschiedene Altersbereiche getrennt für Männer und Frauen berechnet. Die Wertigkeit der HRT als Risikoprädiktor nach Myokardinfarkt nahm mit dem Alter deutlich ab und war bei Frauen niedriger als bei Männern. Eine Strategie zur Risikostratifizierung, die auf der HRT basiert, sollte daher das Alter und das Geschlecht des Patienten berücksichtigen.The study was conducted to evaluate Heart-Rate Turbulence (HRT) as a risk predictor after acute myocardial infarction in a gender specific manner. The endpoint of the study was all-cause mortality. One thousand six hundred fifty-seven survivors of acute myocardial infarction (24% women, 76% men) were enrolled. HRT is a stronger risk predictor in men than it is in women. Its quality as risk predictor decreases with age. Therefore a strategy of risk prediction after myocardial infarction has to take into account the patient´s age and gender
HPLC profiling and quantification of active principles in leaves of Hedera helix L.
No full textPubMed: 15544055Ivy (Hedera helix L., Araliaceae), is an evergreen medicinal and ornamental plant. Depending on leaf polymorphism different shaped ivy leaves were extracted and subsequently analyzed by reversed-phase high performance liquid chromatography (RP-HPLC). Quantitative determination of its most prominent saponins hederacoside C (1) and ?-hederin (2) from different ivy leaf extracts were detected, validated and optimized for quick profiling. The linearity of response, repeatability and reproducibility of the applied RP-HPLC method are reported

Crystallization of trans 1, 4 polyisoprene morphology and kinetics.
No full textPhDA detailed electron microscopic study of the morphology and
kinetics of crystallization of trans-1,4-polyisoprene with cis
isoprene units varying from Of to 19.8 has been carried out.
Two crystal structures of trans3., 4-polyisoprene (LIS and in p)
were generally observed.
In an unstrained film, lamellar single crystals which developed
into hedrites, sheaves and spherulites of both crystal modifications
were observed. The morphology attained was determined by the
growth rate and the nucleation density of the crystals. Electron
diffraction study suggests that the lamellar crystals have a
chain-folded configuration. In a strained film, a row nucleation
morphology was observed LIT and FIMP lamellar crystals were observed
to nucleate from the same central 'backbones'. The row nucleation
density of the lamellar crystals increases with strain. The growth
habits of the lamellar crystals in, both strained and unstrained
films were dependent on the film thinness, and on the proximity
and the orientation of the neighbouring crystals. Models for
the observed growth habits were discussed.
The lamellar thickness data agrees with the kinetic theory of
chain folding. The lamellar thickness of both crystal structures
increases with decreasing degree of supercooling. The fold surface
free energies estimated were 45.1 x 10-3 J/n2 and 60.1 x 10-3 J/m2
for the LIT and F ULF crystals of gotta percha respectively.
The growth kinetics data of the lamellar crystals determined
agrees with the existing theories of crystal growth. At the range
of temperature from 400 to 560, the HMF crystal has a faster growth
rate than the LMF crystallized at the same temperature. At the
same degree of supercooling, the LMF crystal has a faster
growth rate. The growth rates of both the LMF and HMF crystals
decrease as the cis content on a trans polymer chain increases.
With 66 cis units, the growth rate of the isomerized specimen
decreased to a value of 1/6 to 1/8 of that for gutta percha (0f
cis), whereas in cis-polyisoprene, the growth rate is retarded
by 100 times with the inclusion of trans isoprene unit.
This, difference in behaviour is discussed in terms of the possibility
of including non-crystallizable units in the crystal lattice.
The growth rate analysis showed the importance of determining
the equilibrium melting temperature and glass transition
temperature for each isomerized specimen to obtain meaningful
estimates o
