Chlorophyll a is the predominant type of chlorophyll found in green plants and algae. So when you say go green, you know what lies beneath the green mystery! Chlorophyll a constitutes approximately 1 to 2% of the dry weight of planktonic algae. To measure chlorophyll-a, a volume of water from a particular depth is filtered through a fine glass-fiber filter to collect all of the particulate material greater than about 1 micron (1/1000th of a millimeter) in size. Australian and New Zealand Governments, and Australian state and territory governments, 2018. Higher chlorophyll a levels are also common during the summer months when water temperatures and light levels. One of the symptoms of degraded water quality condition is the increase of algae biomass as measured by the concentration of chlorophyll a. Human Metabolome Database (HMDB) 11.6 Chemical Co-Occurrences in Literature. DrugBank. These measurements give scientists valuable insights into the health of the ocean environment, and help scientists study the ocean carbon cycle. Excessive amounts of algae (chlorophyll-a) can cause detrimental effects to the aquatic organisms through wide swings (daily cyclical variations of high and low concentrations) in the amount of oxygen and the pH of the water. The highest chlorophyll concentrations, where tiny surface-dwelling ocean plants are thriving, are in cold polar waters or in places where ocean currents bring cold water to the surface, such as around the equator and along the shores of continents. 2.

DE BOUW VAN STICHTING ZES IS VOLOP BEZIG!

 

WonenBreburg bouwt het pand voor ons, de bewoners betalen de huur uit eigen inkomen en de 24-uurs zorg wordt betaald uit het persoonsgebonden budget van de bewoners.
Maar…….de financiering van de gezamenlijke woonruimte/keuken en de broodnodige domotica moet worden opgebracht door de bewoners en hun ouders.

 

De domotica behelst een systeem waarmee de bewoners de aanwezige zorg kunnen bereiken op momenten dat ze dat nodig hebben, dit werkt via een beeldscherm op het appartement. Ook kan via dit systeem alarm worden gemaakt als er direct hulp nodig is. Het systeem kan later, bij het ouder worden van de bewoners, met modules worden uitgebreid naar individuele behoefte bijv. valdetectie.

 

Voor de inrichting van de woonruimte/keuken, tuin en de aankoop van de domotica heeft ZES nog wat financiële ondersteuning nodig naast de eigen inbreng van ouders en bewoners.

 

Draagt u ons project een warm hart toe, voelt u zich betrokken bij onze bijzondere doelgroep en gelooft u in ons plan, dan hopen wij dat u ons financieel zou willen steunen in het realiseren van dit prachtige woonproject!
