Books or babies? The incapacitation effect of schooling on minority women
This paper examines the effects of an increase in the compulsory school leaving age on the teenage fertility of Roma women, a disadvantaged ethnic minority in Hungary. We use a regression discontinuity design identification strategy and show that the reform decreased the probability of teenage motherhood among Roma women by 13.4–26.0% and delayed motherhood by 2 years. We separate the incapacitation and human capital effects of education on fertility by exploiting a database that covers live births, miscarriages, abortions, and still births and contains information on the time of conception. We find that longer schooling decreases the probability of getting pregnant during the school year but not during summer and Christmas breaks, which suggests that the estimated effects are generated mostly through the incapacitation channel
FRACTURE MECHANICAL ANALYSIS OF HUMAN SKULL
We provide, in this work, estimation of critical value of stress intensity factor of the human skull (KIC). Our research assists examinations concerning dynamic effects exerted on human skull (cracks, etc.)
THE APPLICATION OF PROBABILITY-DENSITY FUNCTION IN FIRING
In high-performance steamboilers of power stations pulsation in the firing chamber often occurs. Pulsation can be determined by measuring the pressure vibration. According to experience they have a stochastic character and their information content can be analyzed with the help of probability laws. The direct analytical description of such signals is not possible, these can only be referred to with statistical data, or characteristic functions
High Magnetic Shear Gain in a Liquid Sodium Stable Couette Flow Experiment; A Prelude to an alpha-Omega Dynamo
The -phase of the liquid sodium - dynamo experiment
at NMIMT in cooperation with LANL has successfully demonstrated the production
of a high toroidal field, from the radial
component of an applied poloidal magnetic field, . This enhanced toroidal
field is produced by rotational shear in stable Couette flow within liquid
sodium at . The small turbulence in stable Taylor-Couette flow
is caused by Ekman flow where . This high
-gain in low turbulence flow contrasts with a smaller -gain in
higher turbulence, Helmholtz-unstable shear flows. This result supports the
ansatz that large scale astrophysical magnetic fields are created within
semi-coherent large scale motions in which turbulence plays only a smaller
diffusive role that enables magnetic flux linkage.Comment: 5 pages, 5 figures, submitted PRL revised version: add one author,

A method for finding new sets of axioms for classes of semigroups
We introduce a general technique for finding sets of axioms for a given class of semigroups. To illustrate the technique, we provide new sets of defining axioms for groups of exponent n, bands, and semilattices
