Article Synopsis
- - The study uses the advanced LISST-RTSSV sensor to measure particle size distributions (PSD) in sediment plumes created by a deep seabed nodule collector vehicle in the Pacific Ocean, revealing significant differences from lab-based measurements.
- - Particle size and shape characteristics depend on several factors such as the maneuvers of the collector vehicle, the time after sediment discharge, and the hydrodynamic conditions in the area.
- - Results show that after complex maneuvers, PSDs stabilize and resemble those from simpler maneuvers within ten minutes, highlighting the need for accurate PSD data in sediment plume transport models.
Little is known about long-term mental health in young adults who participate in ongoing grief counseling programs after early parental death in childhood, adolescence or young adulthood. The purpose of this study was to examine mental health in young adults according to early parental death and participation in grief counseling. : In a cross-sectional, questionnaire-based study, we included three samples of young adults age 18-41 years.

The purpose of this study was to investigate the association between early parental death before the child reaches age 30 years and subsequent use of antidepressants.
Methods: Our nationwide population-based cohort of persons born in Denmark in 1970-1990 with follow-up in the period 1997-2009 comprised 1,124,215 persons, of whom 71,380 were bereaved.
Background: Early parental death is one of the most stressful childhood life events and may influence subsequent psychological health. We investigated the association between early parental loss and risk of hospitalization for an affective disorder in adulthood.
Methods: Our nationwide register-based cohort study comprises 1,225,660 people born in Denmark in 1970-1990, of whom 138,893 experienced the death of a parent before the age of 30 years.
We describe a method of designing shaped focal plane detectors for achieving a range of objectives in measurement of particles suspended in a fluid. These detectors can be designed to measure the total concentration in a wide size range (e.g.
View Article and Find Full Text PDFWe present in-water forward scattering phase functions covering the angle range 0.08 to 16 degrees for 19 narrow-sized dispersions of randomly shaped sediment grains. These dispersions cover particle size range from 1 to 20 microns.

Method: A 5-year prospective intervention study comprising 2,391 employees from different organizations in the human service sector: social security offices, psychiatric prison, institutions for severely disabled, hospitals, and homecare services. Data were collected at baseline and at two follow-ups.
