Abstract:
The root system of plants is generally regarded as a factor, which is in relation to important agronomic and ecological characteristics. The aim of this study was to investigate the effect of high initial stand density on the reduction in development of lucerne root morphology traits and how long-term this effect would be. In spring 2003, a field experiment with six lucerne entries in randomized blocks was established. Broadcast sowing was used and the seeding rate was 5000 germinated seeds per m2. In 2003–2009, the plants were sampled in each plot in autumn; the average depth of sam

Abstract:
Osteoporosis is a condition involving decreased bone mineral density (BMD) and increased fragility of the skeletal system. Osteoporosis affects ~75 million individuals in the United States, Europe, and Japan. In the United States alone, hip fractures affect 500,000 individuals per year, and annual healthcare costs for osteoporotic fractures are approximately $14 billion. A high peak BMD can prevent or delay the onset of osteoporosis and its complications. Exercise and diet may affect peak BMD by as much as 20 to 40% each and have been identified as the two most important controllable factor

When the speed of a fluid exceeds that of sound, discontinuities in density occur, called shocks.The opposite limit from incompressibility (constant density) is constant pressure. In this limit, we get Burgers equation. It can be solved exactly in one dimension using the Cole–Hopf transformation. The limit of small viscosity is found not to be the same as zero viscosity: there is a residual drag no matter how small it is. The Maxwell construction of thermodynamics was adapted by Lax and Oleneik to derive rules for shocks in this limit. The Riemann problem of time evolution with a discontinuous

This paper introduces a new method to address this problem by wing section sacrificial anode with large surface area at initial period. Experiment results showed that the wing section sacrificial anode can output 30-40% more current density than the long slender stand-off, while L ≥ 4r.

Abstract:
According to the current standard specifications and special provisions within the Illinois Department of Transportation, four quality assurance (QA) parameters are used to assess acceptability to remain in place for hot-mix asphalt (HMA) construction projects. However, when these parameters fall outside acceptable limits, it is not clear what impact this has on the pavement service life. This report, therefore, conducted a thorough literature review of studies on QA parameters and their effects on pavement service life and studied the standard specifications of each state to determine what th

Abstract:
The paper discusses information and communication technology use for studying reasons of aviation accidents because of the aviation operator errors as result of internal and external influence. The model and technique are proposed and include integrated ICT united previously developed (initial professional selection and day-to-day pre-shift check), open access cloud-based (NASA and ICAO) and real-time operative (air traffic controllers and pilots control) ICTs, which data are stored in one database. Proposed ICT has been checked to study effect of the solar wind parameters (speed and density)

Abstract:
The engineering behavior of frozen soils is critical to the serviceability of civil infrastructure in cold regions. Among various geophysical techniques, electrical resistivity imaging is a promising technique that is cost effective and provides spatially continuous subsurface information. In this study, under freeze–thaw conditions, we carry out lab–scale 1D electrical resistivity measurements on frost–susceptible soils with varying water content and bulk density properties. We use a portable electrical resistivity meter for temporal electrical resistivity measurements and thermocouples for t

Abstract:
This study presents a major development to the wave method, a methodology used for structural identification and monitoring. The research team tested the method for use in structural damage detection and damage localization in bridges, the latter being a challenging task. The main goal was to assess capability of the improved method by applying it to a shake-table-tested prototype bridge with sparse instrumentation. The bridge was a 4-span reinforced concrete structure comprising two columns at each bent (6 columns total) and a flat slab. It was tested to failure using seven biaxial excitation

Abstract:
The purpose of this analysis is to monitor changes in the spatial patterns of overflights at Mount Rushmore National Memorial (MORU) after the implementation of the park’s Air Tour Management Plan (ATMP). Overflights were compared across 2023 and 2024 using Automatic Dependent Surveillance–Broadcast (ADS-B) data collected over identical timeframes, May 15th to June 25th. This report expands upon an initial 2022 study that revealed a ring-like spatial pattern of overflights near MORU below 1600 feet mean sea level (MSL; Peterson et al., 2022). Data processing followed standardized protocols usi
