The intention of this study was to analyze in how far a computer assisted training for brain damaged adults can be used for the practice with children. Healthy children of different ages were trained with this attention and concentration programme. The results should help to adapt the training programme for the use in brain damaged children. Age-groups differed significantly in level of performance. Data showed that in comparison to Kindergarten-children, first-grade children showed a higher benefit from the training. Implications for modifications of the training-programme are discussed. Other parameter of performance (reaction-time, errors) in relation to school age provide clues to the distribution of structure of difficulty in the programmes. A questionnaire assessing motivation before and during the training, intelligibility of the task, feasibility of the computer and adequacy of the test in children showed that sustained motivation can be achieved provided the training is used in an adaptive way. Thereby demotivating with too easy tasks as well as frustration caused by difficult tasks can be avoided. In general, there was good acceptance of the computerised cognitive training. The presence of a therapist during every training session proved to be necessary in children under the age of 6 years.

Research has shown that physical activity on prescription (PAP), used in Swedish healthcare, increases patients' physical activity, but data are lacking regarding the long-term effects of PAP on exercise capacity. Therefor exercise capacity was evaluated in patients with metabolic risk factors, after 4.5 years of PAP treatment provided by physiotherapists in primary healthcare.

Purpose: This study aimed to initially test whether machine learning approaches could categorically predict two simple biological features, mouse age and mouse species, using the retinal segmentation metrics.
Methods: The retinal layer thickness data obtained from C57BL/6 and DBA/2J mice were processed for machine learning after segmenting mouse retinal SD-OCT scans. Twenty-two models were trained to predict the mouse groups.
Novel Collector of a Dodecylpyridinium Chloride Ionic Liquid in the Reverse Flotation Separation of Muscovite from Apatite.

Reverse flotation separation of muscovite from apatite using a dodecylpyridinium chloride (DPDC) ionic liquid as the collector was studied in this work. The microflotation results depicted that DPDC had a strong collecting for muscovite but had a slight collecting for apatite when using phosphoric acid as a depressant for apatite in a weakly acidic pH value pulp, artificial mixture mineral flotation showed that reverse flotation separation of muscovite from apatite can be effectively achieved in the reagent scheme of phosphoric acid/DPDC, and DPDC had a better separation performance in the muscovite/apatite system than DDA. The adsorption measurements indicated that the adsorption amount of DPDC on the apatite surface was less than that of DPDC on the muscovite surface, and the zeta potential results confirmed that a strong interaction occurred between DPDC and the muscovite surface, while an extremely weak interaction occurred between DPDC and the apatite surface in the presence of phosphoric acid at pH ∼ 5.

Keeping track of time intervals is a crucial aspect of behavior and cognition. Many theoretical models of how the brain times behavior make predictions for steady-state performance of well-learned intervals, but the rate of learning intervals in these models varies greatly, ranging from one-shot learning to learning over thousands of trials. Here, we explored how quickly rats and mice adapt to changes in interval durations using a serial fixed-interval task.
