The effect of Gibberellic Acid (GA3) and Benzyladenine (BA) on Aloe vera was evaluated at pot cultivation conditions. This study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 and BA at 0, 100...

Walnut Anthracnose is among the major diseases of walnut trees in Qazvin Province which is scattered as an epidemic disease in the recent years. This research is designed to study and comparison of control methods of Anthracnose disease in walnut trees of Roodbar region. After selecting the infected garden and implementing winter and spring spraying treatments, winter spraying treatment and con...

Pesticides are essential for removing plant pests and sustaining good yields on agricultural land. Excessive use has detrimental repercussions, such as the depletion of soil fertility proliferation immune insect species, Nilaparvata lunges Nezara viridula. Unmanned aerial vehicle (UAV) variable-rate spraying offers a precise adaptable alternative strategy overcoming these challenges. This study...

OBJECTIVE To evaluate the residual effect of pyrethroids on the mortality rates of Anopheles in order to check their efficacy in indoor residual spraying in the Amazon Region, Brazil. METHODS The study was conducted in public housing units in the city of Belem, Northern Brazil, in 2003. Twelve houses were randomly chosen, three in each of the four established areas. Pyrethroids cypermethrin w...

BACKGROUND & OBJECTIVES Indoor residual spraying (IRS) is a proven tool to reduce visceral leishmaniasis vectors in endemic villages. In India IRS is being done with stirrup pumps, whereas Nepal, Bangladesh, and other countries use compression pumps. The present study was conducted with the objectives to compare the efficiency, cost and user friendliness of stirrup and compression pumps. METH...

Biofabrication commonly involves the use of liquid droplets to transport cells to the printed structure. However, the viability of the cells after impact is poorly controlled and understood, hampering applications including cell spraying, inkjet bioprinting, and laser-assisted cell transfer. Here, we present an analytical model describing the cell viability after impact as a function of the cel...

The ultrafine aerosol emitted by thermal spraying of metals using flame and electric arc processes has been characterized in terms of particle size distribution and emission rates based on both particle number and mass. Thermal spraying of Zn, Zn/Al, and Al was studied. Measurements taken using an electrical low pressure impactor and a condensation nucleus counter reveal an aerosol made up of v...

Information that is presently available makes chemical control of sagebrush (Artemisia’ tridentata) a practical operation. Yet additional information is needed regarding ecological responses to assure that the practice of spraying for sagebrush control will be used wisely. The economy of brush control must be determined by the amount of forage and meat products gained; however, the principal ob...

A robotized manufacturing cell of pre-fabricated GRC (Glass Reinforced Cement) panels for construction industry has been developed by DISAM for the Spanish construction company Dragados, S.A.The main contribution of the developed system is the automatic program~ ming and control of the whole plan. The architect's 3D-drawing of the building facade done on a CAD system serves as input. From the C...
