    • The present application relates to a balanced cascade recirculating deep water culture hydroponic system (BCRDWC) suitable for use in hydroculture. The present invention provides one or more root zone containers having a nutrient inlet and a nutrient return, a valve connected to the nutrient inlet, a head sump unit 100 having a head sump container, pump 101, primary outlet (201, figure 3) and nutrient return 204, the pump pumping liquid from the head sump container through feed lines and into the one or more valve controlled root zone containers (306, 302). A pipe 102 may extend from the pump which splits into an outlet arm 105 and a waste arm 104, the outlet arm being connected to the head sump feed outlet and the waste arm connected to a waste outlet 106. A method of using the system and a kit of parts are also disclosed The system is designed such that all plants in the system may be provided nutrient solution at a balanced rate despite any difference in distance from the head sump unit.

    • An analytical test strip ("ATS") for use with a hand-held test meter in the determination of an analyte in a bodily fluid sample includes an electrically insulting substrate (102), a first patterned conductor layer (104) disposed on the electrically insulating substrate and having a working electrode (128a, 128b) and a reference electrode (130). The ATS also includes an enzymatic reagent layer (106) disposed on the working electrode, a first patterned spacer layer (108) disposed over the first patterned conductor layer and defining both a first sample-receiving channel (112) and an analyte determination sample chamber (114) within the ATS, and a second patterned spacer layer (110) disposed over the first patterned spacer layer and defining at least a second sample-receiving channel (120). The ATS further includes a bodily fluid phase-shift sample chamber (116) in fluidic communication with the second sample-receiving channel. The first sample-receiving channel (112) and analyte determination sample chamber (114) are isolated from the second sample-receiving channel (120) and bodily fluid phase-shift sample chamber (116).
