    Notes: [Auszug] The radiometer1"3 has six channels, each accepting infrared radiation emitted by carbon dioxide in the atmosphere below the satellite at wavelengths of approximately 15 urn. The radiation measured by channel A originates in a layer approximately 20 km thick centred at the 2 mbar (42 km) level, ...

    Notes: [Auszug] The SCR on Nimbus 5 is a more advanced instrument and possesses: (1) It has a narrow field of view, equivalent to ~25 km resolution at the Earth's surface, which means that observations of areas which are cloud free or which have uniform cloud cover are more likely than with Nimbus 4. (2) It has ...

    Notes: Abstract Wind, temperature and humidity fluctuations have been recorded using a sonic anemometer-thermometer, a thrust anemometer, and a La humidiometer. The two anemometers agree in wind speed and stress. Exchange coefficients for momentum, heat and moisture are found to agree with values measured over other bodies of water.

    Description / Table of Contents: Résumé Une enquête a été effectuée dans plusieurs régions du Botswana pour déterminer comment l'exploitation, l'environnement et l'aphosphorose influençaient la condition physique et les facultés reproductrices du bétail nomade de ces régions. Les résultats montrent qu'une médiocre exploitation, le surpàturage et de faibles possibilités d'abreuvement diminuaient sérieusement la condition physique et les facultés reproductrices. Une bonne conduite aide beaucoup à améliorer la situation. L'aphosphorose s'observe dans quelques régions mais elle paraît être étroitement liée à la malnutrition.
    Abstract: Sumario Sellevó a cabo una investigación de campo en varias areas en Botswana para determinar como el manejo, ambiente y posiblemente la afosforosis afectaban la condición corporal y la performance reproductiva del ganado en pastoreo en estas areas. Los resultados indicaron que el manejo pobre, el sobrepastoreo y la pobreza de agua afectaron seriamente la condición corporal y el rendimiento reproductivo. El buen manejo ayuda enormemente en mejorar la situacion. La afosforosis ocurre en algunas areas pero parece estar estrechamente ligada a la malnutricion.
    Notes: Summary A field investigation was undertaken in several areas of Botswana to determine how management, environment and possibly aphosphorosis affected the bodily condition and reproductive performance of range cattle in these areas. Results indicated that poor management, overgrazing and poor watering facilities seriously impaired bodily condition and reproductive performance. Good management helps greatly to improve the situation. Aphosphorosis does occur in some areas but appears to be closely linked with malnutrition.

    Description / Table of Contents: Résumé Les taux de phosphate inorganique dans le sérum du bétail du Botswana sont régulièrement faibles à la fin de la saison sèche. Les taux varient d'une zone à l'autre mais ce n'est que dans quelques régions qu'ils sont compatibles avec ceux qui sont observés dans l'aphosphorose. Its sont les plus bas dans les régions à maigre pâturage mais les faibles taux sériques ne sont pas forcément associés à des signes cliniques d'aphosphorose. Des suppléments de farine d'os augmentent les taux sériques et leur effet est le plus net quand les animaux disposent d'un bon pâturage.
    Abstract: Sumario Los niveles de fosfato inorganico en el suero de ganado en Botswana al final de la estación seca estuvieron en el limite normal inferior. Los niveles variaron de una area a otra y solo en algunas aresa los niveles eran compatibles con aquellos vistos en afosforosis. Los niveles mas bajos fueron vistos en areas de pastoreo pobre pero niveles reducidos en el suero no estaban necesariamente asociados con síntomas clínicos de afosforosis. Suplementos de harina de hueso incrementaron los niveles de fosfato inorganico en el suero y el efecto era mucho mas marcado cuando los animales tenían buena capacidad para el pastoreo.
    Notes: Summary Serum inorganic phosphate levels in Botswanan cattle at the end of the dry season were in the low normal range. Levels varied from one area of the country to another and only in some areas were the levels compatible with those seen in aphosphorosis. Levels were lowest in areas with poor grazing but low serum levels were not necessarily associated with clinical signs of aphosphorosis. Bonemeal supplements increased serum inorganic phosphate levels and its effect was most marked when animals had good grazing available.

    Description / Table of Contents: Résumé Le phosphore minéral, le calcium et le magnésium sériques ont été dosés dans des échantillons de sang prélevés sur trois groupes de vaches en lactation recevant différents additifs alimentaires et sur un groupe témoin; le rapport calcium phosphore a été déterminé. Les taux de phosphore sérique s'élevaient significativement quand les vaches recevaient des suppléments minéraux.
    Abstract: Sumario Tres grupos de vacas lactantes que recibieron diferentes aditivos alimenticios y un grupo control fueron sangrados por suero y el nivel de fosfato inorganico en el suero, tanto como calcio, magnesio y tambien el nivel de calcio: fosfato inorganico fueron estimados. Los niveles de fosfato inorgánico en el suero fueron aumentados en forma significativa cuando las vacas recibieron suplementos minerales.
    Notes: Summary Three groups of lactating cows receiving different feed additives and one control group were blood sampled and serum inorganic phosphate, calcium, magnesium and the calcium: inorganic phosphate ratio were estimated. Serum inorganic phosphate levels were raised significantly when cows received mineral supplements.
