We examine the relationship between the lynching of African Americans in the southern United States and subsequent county out-migration of the victims' surviving family members. Using U.S.

Sequential extraction procedure to obtain the composition of terrigenous detritus in marine sediments.

The geochemical and isotopic composition of terrigenous clays from marine sediments can provide important information on the sources and pathways of sediments. In order to extract the detrital signal from bulk marine sediments, standard sediment leaching methods are commonly applied to remove carbonate and ferromanganese oxides. In comparison to most previous studies that aimed to extract the terrestrial signal from marine sediments we additionally applied a CsCl wash throughout the sample preparation Simon et al.

Reticulate hyperpigmentation in systemic sclerosis: a case report and review of the literature.

Introduction: Systemic sclerosis is a systemic connective tissue disease with variable cutaneous presentations. Although pigmentary disturbances have been described in systemic sclerosis, a reticulate hyperpigmentation has only been reported in one case of systemic sclerosis to date.

Case Presentation: We describe a previously healthy 51-year-old Thai woman who presented with a reticulate hyperpigmentation affecting her trunk and extremities, together with sclerodactyly and proximal sclerosis, resulting in a new diagnosis of systemic sclerosis.
