Electron-positron pairs can be produced via the Schwinger mechanism in presence of strong electric fields. In particular, fields involved $\alpha$ decay and nuclear fission are enough to produce them. The energy $e^+e^-$ pair is related relative distance velocity daughter nuclei. Thus, distribution give information about dynamics processes. A neck model used illustrate how as a probe dynamics.

The centriole, organizer of the centrosome, duplicates by assembling a unique daughter identical to itself in overall organization and length. The centriole is a cylindrical structure composed of nine sets of microtubules and is thus predicted to have nine-fold symmetry. During duplication, a daughter lacking discrete microtubular organization first appears off the wall of the mother centriole....

We discuss Strassler’s hypothesis of matching nonperturbative effects in orbifold pairs of gauge theories which are perturbatively planar equivalent. One of the examples considered is the parent N = 1 SU(N) supersymmetric Yang-Mills theory and its nonsupersymmetric orbifold daughter. We apply two strategies allowing us to study nonperturbative effects: (i) low-energy theorems; (ii) putting the ...

This article studies Sir Walter Scott’s use of the family-as-nation trope in Ivanhoe and Anne of Geierstein. The importance of this trope in his figuration of nationhood is discerned by carrying out a close reading of the texts and placing them in their historical context, which primarily consists of a comparison with Edmund Burke and Maria Edgeworth. Consequently, his position is revealed as b...

During enzymatic replication of plasmids containing the origin of the Escherichia coli chromosome, oriC, formation of an active initiation complex consisting of dnaA, dnaB, dnaC, and HU proteins, requires a supercoiled DNA template. Relaxed covalently closed plasmids are active only if supercoiled by gyrase prior to initiation; nicked and linear DNAs are inactive. Semi-conservative replication ...

OBJECTIVE Using a feminist social constructionist perspective, we illuminate how aging mothers and their caregiving daughters negotiate issues of connection, autonomy, and conflict. METHODS We conducted a qualitative analysis of videotaped interactions between 31 White mother-daughter pairs. RESULT We found that the mothers and daughters mostly (a) were attentive and responsive, (b) preserv...

BACKGROUND Few studies have examined parent-child resemblance in body weight status using nationally representative data for the US. DESIGN We analyzed Body Mass Index (BMI), weight status, and related correlates for 4,846 boys, 4,725 girls, and their parents based on US nationally representative data from the 2006 and 2007 Medical Expenditure Panel Survey (MEPS). Pearson partial correlation ...

BACKGROUND We conducted a cohort study in an attempt to determine whether prolonged pregnancy in mother is a risk factor for prolonged pregnancy in daughter, and if previous prolonged pregnancy is a risk factor for prolonged pregnancy in subsequent pregnancy. METHODS Data from the Swedish Medical Birth Registry were combined with a local registry of births (1955-1990). Mother-daughter pairs (...

This study aimed to develop a model for parent-adolescent daughter communication about sexuality (PDCS). The subjects were 18 mother-doughter pairs. The females were 12-13 years old studying in the 7th grade of a secondary school in Bangkok. The model had 3 parts: (1) the process of PDCS development, (2) the essential components, characteristics and patterns of PDCS and (3) the impact of the pr...

The article analyzed the lifestyle and physical development of Ukrainian adolescents their parents estimated familial aggregation heritability body mass index activity. 408 nuclear families were examined (1216 people with complete information). Anthropometric measures such as weight, height measured following standardized procedures WHO. Questionnaires used to estimate levels method genetic epi...
