Abstract: An agricultural mulch film including two or more layers with different capacities of light absorption and being separable from each other, e.g. by degrading at different speeds and/or having different times of degradation.

Abstract: A method and a system for detection of presence or absence of analytes in fluids, the method comprising the steps of: a) contacting a fluid sample and a plurality of nanoparticles, the nanoparticles being functionalized with a selective ligand, the contact of the fluid sample with the nanoparticles being under conditions such that, the nanoparticles aggregate selectively on surface of their target analyte, forming a nanoparticle-analyte complex, the aggregation promoting the concentration of the nanoparticles on the surface of the target analyte; b) subjecting a fluid mixture of the fluid sample and the plurality of nanoparticles to SERS; c) measuring at least a SERS signal associated with the fluid mixture; d) spectrally analyzing the at least one SERS signal of step c); e) recognizing at least one defined SERS spectrum of the nanoparticle-analyte complex, through a SERS signal enhanced by the at least one narrow inter-nanoparticle gap.

Abstract: The invention relates to a system for constructing walls using blocks equipped with coupling means, comprising blocks having: ridges that fit into grooves, bases that fit into channels, cavities for the flow of adhesive, notches in which ducts for installations are located, perforations for reinforcing the wall with post-tensioned cable or rebar, provisions for building frames for doors or windows, and tunnels for housing piers, among other elements, which together allow a wall to be constructed without skilled labor, saving materials and reducing construction time.

Abstract: A new and distinct cultivar of stevia plant named ‘AKH L4’, characterized by its combination of early cycle, dark green leaves, medium number of nodes on the main stem, high number of basal buds, high Rebaudioside A of total Glycoside Steviol content, and high yielding of dried leaves at harvest.

Abstract: A new and distinct cultivar of stevia plant named ‘AKH L1’, characterized by its combination of late cycle, light green or yellow green leaves, high number of nodes on the main stem, medium number of basal buds, high Rebaudiosido A of total Glycoside Steviol content, and high yielding of dried leaves at harvest.

Abstract: An opening switch (1) for vehicle doors or rear hatches comprises an actuator device (5) for activating a microswitch (6) which can be moved between two positions: a first open position in which the actuator device is kept away from the microswitch (6), and a second closing position in which the actuator device is in contact with the microswitch (6). The actuator device for activating the microswitch (6) comprises a rocking actuator (5) which incorporates within itself at least one pair of elastic tongues (7) whose reaction brings about return of the rocking actuator (5).

Abstract: A portable automotive vehicle radiator repair shop is mounted on an automotive vehicle. The vehicle is equipped with an immersion tank having an open top and a drain beneath and a power lift having a platform moveable to submerge and raise a radiator to be repaired which is positioned thereon. The vehicle has a water distribution system with a female garden hose coupling as a water inlet. The vehicle is also equipped with a pneumatic reservoir having a pneumatic inlet coupling adapted to receive an air hose of the type with which most service stations and garages are equipped. The vehicle is also equipped with a blowtorch, a propane tank and an oxygen tank. The propane and oxygen tanks are connected to the blowtorch. The propane and air supply from the pneumatic tank are connected to a drying torch and the water distribution system and pneumatic air supply are connected to a flushing nozzle. A paint reservoir and paint sprayer are also employed and the paint sprayer is connected to the pneumatic tank as well.
