Kinematic 3D Retro-Deformation of Fault Blocks Picked from 3D Seismics
Movement on fault planes causes a large
amount of smaller-scale deformation,
ductile or brittle, in the area surrounding
the fault. Much of this deformation
is below the resolution of reflection
seismics (i.e. sub-seismic, <10m
displacement), but it is important to determine
this deformation, since it can
make up a large portion of the total bulk strain, for instance in a developing
sedimentary basin. Calculation of
the amount of sub-seismic strain around
a fault by 3-D geometrical kinematic
retro-deformation can also be used to
predict the orientation and magnitude
of these smaller-scale structures.
However, firstly a 3-D model of the fault
and its faulted horizons must be constructed
at a high enough resolution
to be able to preserve fault and horizon
morphology with a grid spacing of
less than 10 m. Secondly, the kinematics
of the fault need to be determined,
and thirdly a suitable deformation algorithm
chosen to fit the deformation
style. Then by restoring the faulted
horizons to their pre-deformation state
(a ‘regional’), the moved horizons can
be interrogated as to the strain they
underwent. Since strain is commutative,
the deformation demonstrated during
this retro-deformation is equivalent
to that during the natural, forward deformation...conferenc
Мотивация целевых групп при выводе продукта на рынок
Сделан вывод о том, что при разработке системы мотивации необходимо проводить сегментацию клиентов и персонала по группам преобладающих потребностей, как это делается с рынками в маркетинге. А также выделены целевые группы, влияющие на процесс вывода нового продукта на рынок, и особенности их мотивации
FABRICATION AND ELECTROCATALYTIC APPLICATION OF NI-MODIFIED ELECTRODE TOWARD DETECTION OF PARACETAMOL
In the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. The methods of cyclic voltammetry (CV), chronoamperometry (CA), and impedance spectroscopy (EIS) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coefficient of paracetamol in the bulk of solution. The electrochemical results showed that the modified nickel electrode had a high electrocatalytic activity for the electro-oxidation of paracetamol around 400 mV/Ag.AgCl in alkaline media and the diffusion coefficient of paracetamol was obtained to be 3×10-6 cm2.s-1. It means that the modified nickel electrode is highly sensitive toward the detection of paracetamol

Role of anxiety and depression in association with migraine and myofascial pain temporomandibular disorder
Background: Previous studies have demonstrated a strong association between primary headaches (HAs) and temporomandibular disorders (TMDs), specifically the myofascial pain subtype of TMD (MP TMD). The role of anxiety and depression in presentation and maintenance of MP TMD and migraine is previously demonstrated. Therefore, the objective of the current study was to evaluate the modification effect of anxiety and depression on the possible association of MP TMD and migraine. Methods: In this retrospective case–control study, individuals between 15 and 45 years old who were diagnosed with migraine HA according to the international classification of headache disorder-II (ICHD-II) were selected as case subjects (n = 65). Non-HA control subjects were matched by sex and age (n = 63). Research diagnostic criteria (RDC/TMD) (Axis I) was used to diagnose patients with MP TMD; other subtypes of RDC/TMD Axis I were excluded from the study. Subjects' anxiety and depression were screened using Persian version of Hospital Anxiety and Depression Scale-14. Chi-square and Mantel–Haenszel tests were used to analyze the data. P < 0.05 was considered statistically significant. Results: A significant association was found between migraine and MP TMD so that subjects with MP TMD had a five times chance of developing HA (P < 0.001). Further analysis using stratification method revealed that anxiety and depression have a modification effect in the association of MP TMD and HA and MP TMD patients with anxiety or depression had more chance of developing migraine HA (P = 0.003). Conclusion: Association between HA and TMD was observed in this study. Besides, we depicted that anxiety and depression interact in this association so that patients who did not have anxiety or depression did not demonstrate an association between TMD and HA. We suggest further studies to confirm the modifying effects of anxiety and depression
