The objectives of this study were to investigate a design and experimental fog spraying into a greenhouse roof to control the temperature, relative humidity (%RH), radiation intensity (RI), and storage data system, which will support the maximum quality and quantity of vegetarian production. This study is a novel design and experiment concerning a greenhouse model that uses fogging spray on the roof and inside the greenhouse. The automatic control systems are applied with GY-49 sensors, AMT1001 temperature and humidity sensors and DS1307 real time clock module. The experimental results are shown by LCD monitoring using a real-Time clock (RTC) from 2.00 a.m.To 8.00 p.m. The percentage difference in radiation intensity inside the greenhouse decreased in the range of 69.58 % to 95.00 %. The maximum temperature inside the greenhouse decreased by 12C. The temperature variation ratio of fogging is 80 %, while the relative humidity range of 60-97 %RH.

There is approximately 30% of grey sedge (Lepironia articulata) residue remaining from weaving production that could add value to support zero waste management. Therefore, the aim of this research was to study the feasibility of using a residue of grey sedge or Krajood strips from weaving production to form a value-added product. To obtain preliminary data, Krajood strip residue was examined for its biological and physical properties. In addition, the biological and physical properties of Krajood strip residue in combination with loam soil (KSRL) were examined and compared with the properties of loam soil (LS) itself. The results showed that the total microbe and moisture content of the Krajood strip residue was significantly higher than that of the products made from Krajood strips (KS). The stress value of Krajood strips was higher than the stress values of other samples except for that of a bag made of paper. Identification of bacteria and mold by MALDI Biotyper and DNA sequencing compared with BLAST revealed the presence of the types of soil microbes that benefit plants. KSRL was enriched with larger amounts of the primary elements important for plant growth: nitrogen, phosphorus, and potassium, and the three second tier elements. The pH of KS, LS, and KSRL were 6.40 ± 0.14, 5.87 ± 0.04, and 5.26 ± 0.02, respectively. These results could support the use of this beneficial residue for bioresource sustainability.

The study was the conditioning system of the electronic case by using thermoelectric Peltier module. The Peltier module is used based on the temperature difference of the hot and cold sides, with input electric power in the thermoelectric Peltier module. The hot side of the Peltier module was installed on a side of the heat sinks with heat removing from a Peltier module into a surrounding while the cold side of the Peltier module was installed on the other side of the heat sinks with the heat absorption of the computer case. The electronic case volume is 450x395x240 mm³. The device of cooling loads was installed in the electronic case. The cooling loads were tested with various power of 0, 60, 120, 180, and 240 Watt. The results indicated that the coefficient of performance (COP) increased with the cooling load. Furthermore, the experimental results indicated that the temperature inside the electronic case increased with cooling load because the temperature of the electronic case increased with decreasing the temperature difference between the hot and the cold sides.

A novel system of nanofluidics trapping and delivery, which is known as a tissue culture system is proposed. By using the intense optical pulse(i.e., a soliton pulse) and a system constructed by a liquid core waveguide, the optical vortices (gradient optical fields/wells) can be generated, where the trapping tools in the same way as the optical tweezers in the PANDA ring resonator can be formed. By controlling the suitable parameters, the intense optical vortices can be generated within the PANDA ring resonator, in which the nanofluidics can be trapped and moved (transported) dynamically within the Tissue culture system(a wavelength router), which can be used for tissue culture and delivery in the hydroponic plant system. © 2011 IEEE.

A new optical trapping design to transport gold nanoparticles using a PANDA ring resonator system is proposed. Intense optical felds in the form of dark solitons controlled by Gaussian pulses are used to trap and transport nanoscopic volumes of matter to the desired destination via an optical waveguide. Theoretically, the gradient and scattering forces are responsible for this trapping phenomenon, where in practice such systems can be fabricated and a thin-film device formed on the specific artifcial medical materials, for instance, an artificial bone. The dynamic behavior of the tweezers can be tuned by controlling the optical pulse input power and parameters of the ring resonator system. Different trap sizes can be generated to trap different gold nanoparticles sizes, which is useful for gold nanoparticle therapy. In this paper, we have shown the utility of gold nanoparticle trapping and delivery for therapy, which may be useful for cosmetic therapy and related applications. © 2012 Aziz et al.

A novel design of nanoscopic volume transmitter and receiver for drug delivery system using a PANDA ring resonator is proposed. By controlling some suitable parameters, the optical vortices (gradient optical fields/wells) can be generated and used to form the trapping tools in the same way as the optical tweezers. By using the intense optical vortices generated within the PANDA ring resonator, the nanoscopic volumes (drug) can be trapped and moved (transport) dynamically within the wavelength router or network. In principle, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system (device), which is called a transceiver, which is available for nanoscopic volume (drug volume) trapping and transportation (delivery). © 2011 IEEE.

A novel design of molecular buffer for molecule storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. By using the intense optical vortices generated within the PANDA ring resonator, the required molecules can be trapped and moved (transported) dynamically within the wavelength router or network, in which the molecular buffer can be performed within the wavelength router before reaching the required destination. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system, which is available for molecule storage and transportation. Relevant patents are also reviewed in this manuscript. © 2011 Bentham Science Publishers Ltd.

We propose a novel drug delivery system (DDS) by using a PANDA ring resonator to form, transmit and receive the microscopic volume by controlling some suitable ring parameters. The optical vortices (gradient optical field/well) can be generated and used to form the trapping tool in the same way as the optical tweezers. The microscopic volume (drug) can be trapped and moved (transported) dynamically within the wavelength router or network. In principle, the trapping force is formed by the combination between the gradient field and scattering photons, which has been reviewed. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system, which is called transceiver, in which the use of such a system for microscopic volume (drug volume) trapping and transportation (delivery) can be realized. © 2010 Optical Society of America.

A novel system of an optical vortex generation using an add/drop multiplexer incorporating with two nanoring resonators is proposed. Such a system is known as a PANDA ring resonator structure, in which the optical vortices (gradient optical fields/wells) can be generated and used to form the photon/atom trapping tools in the same way as the optical tweezers. By controlling some suitable parameters of the input and the control optical pulses, the intense optical vortices can be generated within the PANDA ring resonator, in which the trapped photons/atoms can move dynamically within the system. The trapping force occurrs and is formed by the combination between the gradient field and scattering photons, which we review. A transmitter and receiver can be formed within the same system (device), which is called a transceiver. Finally, the use of the PANDA ring resonator as a hybrid transceiver and repeater for nanocommunication is discussed. © 2010 Society of Photo-Optical Instrumentation Engineers.
