Impact of g-Load Shift on Temporal Expression Pattern of Apoptosis-linked Proteins in the Rat Mammary Gland

of proapoptotic proteins during the pregnancy-to-lactation transition in a mammary gland of an experimental animal model. Therefore, in the present investigation, we extended our preceding study to quantify the temporal distribution of apoptosis-related proteins, namely Cleaved Caspase-3 (CC-3), Tumor Protein p53 (p53), and vitamin D receptor (VDR) in the mammary tissue harvested from rats exposed to HG during the periparturient period employing quantitative immunohistochemistry.

Temporal distribution of linear densities of the plasma column in a plasma focus discharge

Abstract

Experiments were carried out on the PF-1000 plasma focus device, with a deuterium filling and with deuterium puffing from a gas-puff nozzle placed on the axis of the anode face. The current was reaching 2 MA. 15 interferometric frames from one shot were recorded with a Nd:YLF laser and a Mach–Zehnder interferometer, with 10–20 ns delay between the frames. As a result, the temporal and spatial distribution of the linear densities and the radial and axial velocities of the moving of plasma in the dense plasma column could be estimated.

Musculoskeletal Outcomes from Chronic High-Speed High-Impact Resistive Exercise

Introduction Musculoskeletal changes to chronic exercise offer a temporal framework for which to anticipate strength improvements and/or attenuation of in-flight losses from exercise hardware and/or protocols. Temporal changes refer to the rate and magnitude of adaptations over time, which help formulate training strategies to limit in-flight strength losses and thereby optimize long-term musculoskeletal health for long-term exposure to microgravity ( Fleck and Kraemer, 2014 ). Two 60-day bed rest studies assessed temporal adaptations to concurrent exercise

Influence of seasonal factors in the earned value of construction

provides output data in monetary units which are compatible with the suggested methodology. On the other hand, the methodology concerning the sample choice leads to setting the territorial, temporal and typological limits. Regarding territorial limits, it should be mentioned that the place where the construction is carried out has some seasonal conditions (climatic, cultural, legal, social, etc.) which is different from other places. For instance, northern hemisphere locations are rather different from southern hemisphere locations, due to obvious climatic reasons

Dimensionless characterization of the non-linear soil consolidation problem of Davis and Raymond. Extended models and universal curves

the other hand, the average degree of settlement is a direct function of the dimensionless characteristic time, while the average degree of pressure dissipation depends, additionally, on the loading ratio, so its universal representation needs to be done by means of an abacus. 2 Davis and Raymond consolidation model 2.1 Davis and Raymond proposed model The general consolidation equation is obtained by matching, in a soil element, the temporal change in water volume with the temporal change in void volume [ 14 ]. This balance, together with the

Galerkin-Chebyshev Pseudo Spectral Method and a Split Step New Approach for a Class of Two dimensional Semi-linear Parabolic Equations of Second Order

spectral method, there are some studies listed in Liu et al. [ 5 ]. We note that in all these studies, especially with spectral methods, the authors used explicit method, which is necessary for the temporal variable, which has stability problem for large time. In this study, we use implicit method for temporal variables, and obtain the solution to semi-linear Poisson-Boltzmann (PB) equation, which is commonly used to characterize electrostatic interactions. Solving numerically the semi-linear PB equation is very challenging due to various factors of the PB model, such

Analysis of simultaneous time series of indoor, outdoor and soil air radon concentrations, meteorological and seismic data

Abstract

It is well known that the temporal dynamic of indoor and outdoor radon concentrations show complex patterns, which are partly not easy to interpret. Clearly, for physical reasons, they must be related to possibly variable conditions of radon generation, migration and atmospheric dispersion and accumulation. The aim of this study was to analyse long-time series of simultaneously measured indoor and outdoor radon concentrations, together with environmental quantities, which may act as control variables of Rn. The study was performed in Chiba, Japan, using two ionization chambers for parallel indoor and outdoor radon concentrations measurements over 4 years. Meteorological and seismic data were obtained from the Japan Metrological Agency (JMA).
