In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis. 相似文献

This study explores the relationship of parenting to internalizing and externalizing problems in Moroccan immigrant youth
in the Netherlands. Interviews were conducted with 713 Moroccan immigrant parents, using the Child Behavior Checklist and
the Nijmegen Rearing Questionnaire. Child rearing varied with socioeconomic status and psychological acculturation level of
the parent, and gender and age of the child. In accordance with studies in Western populations, high levels of affection and
monitoring were associated with low levels of problem behavior and high levels of discipline were associated with high levels
of problem behavior. However, in contrast to studies in Western populations, a positive relationship was revealed between
affection and discipline, and the univariate associations between discipline and problem behavior were modest. Discipline
and internalizing problems were unrelated in low SES families, whereas a positive relationship was found in high SES families.
The relationship between monitoring and externalizing problems was age-specific: We found a negative association for adolescents
and no association for children.
