Internal and External Radiofrequency Assisted Lipo-Coagulation (RFAL) in the Control of Soft Tissue Contraction during Liposuction: Part 1 “Inside Out” Thermal Tissue Tightening

Radiofrequency Assisted Lipo-coagulation (RFAL) BodyTite is a contact, impedance, internal and external thermal regulation controlled, internal, minimally invasive, non-excisional procedure providing soft tissue lipo-coagulation and contraction that has been used for over 10 years to optimize skin and soft tissue contraction during liposuction procedures. The device deploys a bipolar applicator inserted into the liposuction zone. The internal, coated, electrode is positively charged and emits a coagulative, ablative injury that results in adipose liquification and Fibroseptal Network (FSN) contraction. The RF flows from the internal electrode after ablation and coagulation up to the external negatively charged return electrode moving on the skin, which heats and tightens the papillary dermis non-ablatively. The body areas that most benefit from this BodyTite technology and procedure include those areas most in need of non-excision contraction include the abdomen, upper arms, inner thighs, bra-line, neck and jaw line. Studies, show, that the combination of BodyTite internal thermal coagulation and external Morpheus8 (see Part 2) at the time of liposuction can result in 40–70% area skin contraction, greatly improving the soft tissue contours and Body shaping outcomes following lipo-contouring procedures.

Utilizing conductivity of seawater for bioelectric measurement of fish

To manage health conditions of farmed fish and other living creatures, a simple method to measure bioelectric signals of the creatures in seawater is expected. A novel method to measure bioelectric signals by utilizing the conductivity of seawater surrounding the entire body of a fish is proposed. As for the proposed method, a needle-type internal electrode is inserted into the fish’s muscle at a certain measurement point, and an external electrode is sunk in seawater. The internal electrode is isolated from the seawater by virtue of being inserted in the fish. Bioelectric signals generated between the external and internal electrodes are then measured. By sharing the external electrode with the internal electrode, it is possible to measure bioelectric signals with half the number of bioelectrodes used by conventional methods. To demonstrate the practicality of the proposed method, two internal electrodes were inserted into different parts (above the gills and near the tail) of three fish (Parajulis poecilepterus, ca. 20 cm fork length) kept in a tank. The proposed method obtained reliable bioelectric signals corresponding to electrocardiograms (ECGs) and electromyograms (EMGs) from each part of the individual fish.

Investigation of the Pastes for Multilayer Ceramic Capacitors Termination

Multilayer ceramic capacitors (MLCC) have wide application in electronic due to its electrical characteristics: low equivalent series resistance (ESR) and high volume efficiency. One of the MLCC manufacturing problems is the choice of composition for the end pastes. The experimental results of the termination pastes composition influence on the quality high-voltage MLCC investigation are presented. The causes of the defects appearance in the termination are determined, the composition of the termination paste, which ensures the quality contact of the internal electrode with the external, is proposed.

Triggering WORM/SRAM Memory Conversion by Composite Oxadiazole in Polymer Resistive Switching Device

Electrical characterization indicates that the nonvolatile write once read many (WORM) times/volatile static random access memory (SRAM) conversion was triggered by the composite of the oxadiazole small molecule. FTO/PMMA/Ag device possesses nonvolatile WORM memory behavior, while the FTO/PMMA+oxadiazole/Ag device shows vastly different volatile SRAM feature. The FTO/PMMA/Ag and FTO/PMMA+oxadiazole/Ag memory devices both exhibit high ON/OFF ratio nearly 104. The additive oxadiazole small molecule in the polymethyl methacrylate was suggested to form an internal electrode and serve as a channel during the charge transfer process, which is easy to both the charge transfer and back charge transfer, as a consequence, the WORM/SRAM conversion upon oxadiazole small molecule complexation was triggered. The results observed in this work manifest the significance of oxadiazole small molecule to the memory effects and will arouse the research interest about small molecule composite applied in memory devices.
