An economic downturn, higher gasoline prices and increasing unemployment have decimated the discount department store chain’s core market, according to documents filed with a New York bankruptcy court on Sunday.

However, there is uncertainty in the accuracy and consistency of the methodologies used for dating recent peats.

This study compares results from Spheroidal Carbonaceous Particles (SCPs) and natural and anthropogenic fallout radionuclides (Am) used to date three replicate cores from three contrasting sites.

However, all sediments cores exhibited a common denominator consisting on a database built from the use of the same techniques for acquiring the sediments major chemical composition (Si OPb activity data.

In terms of sedimentation rates, the performance of the CRS model was better than that of the CF: CS model as it yielded values more compatible with those expected from field evidences.

Finally, our data suggest the current estimates for SCP-based ages in the region maybe incorrect and require further regional calibration.

Using several techniques on replicate cores from three sites in the same area has provided a more robust evaluation of the likely reliability of individual techniques and the processes that may adversely affect them.

Pb data set providing of eighteen sediments profiles sampled at four riverine systems occurring in Brazil, South America: Corumbataí River basin (S1=Site 1, São Paulo State), Atibaia River basin (S2=Site 2, São Paulo State), Ribeirão dos Bagres basin (S3=Site 3, São Paulo State) and Amazon River mouth (S4=Site 4, Amapá State).

These sites were chosen for a comparative evaluation of the performance of the CF: CS and CRS models due to their pronounced differences on the geographical location, geological context, soil composition, biodiversity, climate, rainfall, and water flow regime, among other variable aspects.

The case claims that Central coerces drivers to stay working for years by refusing drivers permission to use their trucks to deliver freight for other companies, by telling owner operators that if they leave their lease, Central will 1) put the driver in default, 2) report the default to the drivers’ DAC report, 3) demand all remaining lease payments be immediately paid, 4) report all remaining lease payments to the drivers’ credit reports.90% of people who die by suicide have an underlying mental disorder.
