Spray drift mitigation, in the agriculture aerial spraying literature, and spray quality application of plant protection products, still continues as two critical components evaluating shareholder value. A study on off-target ground deposit onto a 250 m strip were simulated through series Computational Fluid Dynamic (CFD) simulations. The patterns for evaporating droplets released from constant aircraft velocity at 30 m/s (60 mph) carrying 20 swath width boom with 12 fan-type nozzles height...

The effects of glycerol content in modified polyvinyl alcohol-tapioca starch were investigated. A series plasticized alcohol (PPVA) and TS blends prepared. Prior to compounding process, PVA was with 15-40 phr as well addition calcium stearate (CaS) phosphoric acid. Blends PPVA at composition 50%, 60%, 70%, 80% 90% 20 compounded using twin screw extruder. PPVA-TS then processed via injection molding produce test specimen for mechanical testing. It found that the blending is compulsory order...

Undoubtedly agricultural is an important sector because it provides essential nutrients for human, and consequently among the biggest economic growth worldwide. It crucial to ensure crops production protected from any plant diseases pests. Thus aerial spraying system on developed facilitate farmers pests control very effective method especially large hilly crop areas. However, use of aircraft spaying has a relatively high operational cost. Therefore, microlight proposed be used works several...

The Wing-in-Ground (WIG) craft represents a pioneering vehicular innovation that exploits aerodynamic lift via cushioning mechanism, enabling it to remain suspended above the water's surface. A notable concern encountered during navigational manoeuvres of WIG over uneven sea terrain pertains its potential impact on fuel efficiency flight durations. This research objective is focused pivotal ascertaining optimal lifting force prerequisites for prototype craft. comprehensive study entails an...

Polycrystalline diamond (PCD) is regarded as among the hardest material in world. Electrical Discharge Machining (EDM) typically used to machine this because of its non-contact process nature. This investigation was purposely done compare EDM performances PCD when using normal electrode copper (Cu) and newly proposed graphitization catalyst nickel (CuNi). Two level full factorial design experiment with 4 center points technique study influence main interaction effects machining parameter...

Malaysia is one of the top ten coconut-producing nations in world, and coconut country's fourth-most significant industrial crop after oil palm, rice, rubber. Coconut production an important source income employment for over 100,000 households that rely entirely or partially on coconut, particularly among smallholders. The sector has given smallholder farmers option to diversify their resources farming while also meeting local demand fresh consumption processing industry. smallholders were...
