Experiments were carried out in order to quantify the transfer ofCo from the environment to various species of a benthic food chain. The food chain tested was composed of the diatom Navicula sp., the bivalve Scrobicularia plana, the shore crab Carcinus maenas, and the rat Rattus rattus. The diatoms take up large quantities of radiocobalt. The radio-activity accumulated (per unit weight) by the organisms studied decreases from one trophic level to the next. This result is particularly interesting from the point of sanitary protection. There is some biological control inCo uptake by these species. For both, invertebrate animals and rat, the quantity ofCo assimilated is independent of the quantity ingested with food. Preferential sites of cobalt accumulation are liver and kidneys in the rat, and hepatopancreas in the two invertebrate species examined. [ABSTRACT FROM AUTHOR]

Background: This paper explored the facilitators and barriers to husbands' involvement in antenatal-related care in the Bosomtwe District of Ghana from the perspectives of husbands, pregnant women with and without delivery experience, nursing mothers, midwives and traditional birth attendants., Methods: The study relied on the qualitative research design to collect and analyse data on the facilitators and barriers to husbands' involvement in antenatal-related care. The unit of analysis was made up of 36 participants-husbands (14), pregnant women with delivery experience and, nursing mothers (8), pregnant women without delivery experience (6), male and female midwives (6) and traditional birth attendants (2) who were purposively selected. The study's data was gathered using in-depth interviews and analysed through the content approach., Results: Various economic [work and time constraint], cultural [the association of childbearing and its allied duties to women] and health-system factors [lack of antenatal services targeted at husbands and health professionals' attitude] hinder husbands' active participation in antenatal care. Despite these, some husbands participated in antenatal care owing to the importance they accord to the health and safety of their wives and the foetus; changing gender roles and preferential treatments received by their wives at antenatal clinics [as a result of the involvement of their husbands in prenatal care]., Conclusion: The implementation of alternative strategies, like, couple counselling, prolonging operating times of health centres to accommodate working men are recommended to provide a more accommodative and attractive avenue for husbands to support their wives during pregnancy. These efforts must be reinforced by the entire society through modifying the "ill-held view" that pregnancy and childcare is the sole duty of a woman., (© 2022. The Author(s).)

The language for interrogating data (LID) allows the graphical and numerical exploration of a cloud of points resulting from a factorial analysis. The interest of a post-factorial analysis in epidemiology is shown in the present paper: a measure of the department effect; a measure of year effect; an assessment of the adjustment on one factor in the framework of a survey on the risk factors of milk quality.

This paper presents a first approach of the health over the whole life-cycle of dairy cows, a scale which is intended to define a trajectory. Trajectories are defined as the chain of health profiles on the lactation scale, which are characterized by major disorders: foul of the foot; lameness; arthritis; calving disorders; mastitis; digestive and metabolic disorders; and no disorders. A few examples of trajectories are discussed for life-cycles lasting 4 lactations.
