Tabanus spp. Horse fly/ Breeze fly/ Gad fly These are very large flies with very large eyes and gap between them is small. Antennae are projected forward in front of the head and have 3 segments. The first 2 segments of the antenna are small‚ the third segment has 4 annulations and has a tooth like projection called spur. Flies hold their wings horizontally at rest. Proboscis is short The mouth part consists of two jointed well-developed palps‚ a pair of well developed mandibles and maxillae

to be exhausted and needs to be regenerated by coming in contact with a strong solution of ions called the regenerant. Sodium zeolite softeners historical used natural zeolite materials but have now been replaced with exchange resins made of polystyrene. These resins have sodium ions loosely attached and will readily give up the sodium for a more desirable ion such as calcium and magnesium. This exchange is only for cations of positively charged ions. This is why sodium zeolite resin is referred

P4 four key methods used to protect the natural environment from the impact of construction Minimisation of pollution Pollution has a marked effect upon the environment as well as on our health and well-being. There are several ways to minimise pollution including: * Fitting fume scrubbers to chimney outputs to remove solids and any pollutant chemicals that would be realised into the air. * Treating water of foul drainage before it is discharged into sea outfalls to reduce the effects
