The preset invention relates to a promoter to target a fluorescent protein to the muscles of fish, such as A. nigrofasciatus, for ornamental purposes, which is a Mlc3 (myosin, light polypeptide 3, skeletal muscle) promoter. The Mlc3 promoter has the nucleotides of tilapia (Oreochromis niloticus) myosin light chain 3 (Mlc3) promoter region, which is potential to be a tilapia Mlc3 promoter to enhance protein expression in muscle of fish, particularly for the generation of ornamental fish.

A combined projector structure having a diverse stable display effect of the scene includes a holding space, in which freely-moving living organisms can be kept, an image device mounted on the edge of the holding space and facing toward the holding space. The image device can include a mounting element installed on the edge of the holding space, a kaleidoscope connected to the mounting element and facing toward the holding space, a photographic unit connected to the other end of the kaleidoscope. The photographic unit can record the scenes that appears in the other end of the kaleidoscope, and a projection unit connected to the photographic unit. Through the kaleidoscope, the displacement of the moving living organisms located in the holding space can be displayed in a diverse visual effect.

A solid and painless sticking bar includes a solid main body and an adhesive member fixed at the underside of the main body. The main body has plural cut lines respectively provided at a proper interval so that the main body can be cut into a proper length or height for use according to practical needs. Plural main bodies are protuberantly fixed at proper locations around the outer circumferential edge of a wound by means of the adhesive member. Thus, when bandaging material is covered or wound on the main bodies and positioned over the wound, it will not directly contact with the surface of the wound and adhere to the wound when the wound secretes mucus, able to prevent the wound from being injured for a second time when the bandaging material is removed from the wound.

The instant disclosure provides a Power Factor Correction (PFC) boost converter including a PFC converter unit and a control unit and a frequency switching modulation method thereof. The control unit outputs a pulse width modulation (PWM) signal to the PFC converter unit for adjusting an electronic power output to a voltage converter. As the output load of the PFC converter unit increases, the control unit increases the frequency of the PWM signal. Conversely, as the output load of the PFC converter unit decreases, the control unit reduces the frequency of the PWM signal. Consequently, the switching loss of the PFC converter unit is reduced.

A stationary LED lamp includes a heat dissipating strip, a lamp cover base, a support strip, and an LED base. The heat-dissipating strip is adhered at an outer side of the lamp cover base, and the support strip is installed at an inner surface of the lamp cover base, which is provided with a reflecting strip on the inner surface. The LED base is provided with more than one LED welded on a PCB, and then adhered at an inner side of the support strip. Then the LED lamp is positioned by means of screwing or adhering, without easily loosening off as a conventional lamp does. The stationary LED lamp has a high luminance and swift heat dissipation to comply with the environment protection more effectively than the conventional one does.

A multifunction plant cultivation LED able to control the growing speed of plants is to properly select the composition material and proportion of LED to enable the LED to emit light with different wavelengths and colors. Then, specific wavelengths beneficial to the growth of plants and able to offer best bright for human naked eyes are selected from light spectrums to make up a LED light source with multiple wavelengths for irradiating landscaping plants and flowers and controlling their growing speed as well as for seeing, enjoying and for lighting, versatile in use, having high efficiency and saving electricity.
