Temperaturmessungen in Afrika

Wer noch nie tropische Länder besucht hat, glaubt leicht, dass es dort immer heiß sei. Auf dem JBL Workshop in Tansania wurden die Tages- und Nachttemperaturen sowie die Temperaturen in der Sonne, als auch im Schatten gemessen. Die Temperaturdifferenzen waren enorm! Morgens um 7:00 Uhr wurden mit 17 °C die niedrigsten, mittags um 15:00 Uhr mit 34 °C die höchsten Werte gemessen. Im Schatten lagen die Temperaturen mittags 5 ° niedriger.

Auch die Beschaffenheit und die Farbe des Untergrundes waren maßgeblich: Helle Steine waren um etwa 2 ° kälter als dunkle Steine und Baumstämme waren mit 30 °C in der Sonne um 4 ° kälter als Steine am gleichen Ort. In Terrarien können die JBL TerraTemp Instrumente sowohl die Temperatur, als auch die relative Luftfeuchtigkeit übersichtlich und genau anzeigen. Für Terrarientiere bedeuten diese Ergebnisse, dass sie Wahlmöglichkeiten brauchen: Heiße, warme und kühlere Regionen im Terrarium, die auch Tagsüber frei gewählt werden können.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
