In this article, we propose a novel simultaneous wireless information and power transfer (SWIPT) scheme for the Internet of Things (IoT). Different from conventional splitting (PS) time switching (TS) schemes, proposed sends via unmodulated high-power continuous wave (CW) transmits by using small modulated signal in order to reduce interference enhance amplifier efficiency. We design receiver circuit processing such SWIPT signals, which is designed with aim minimizing complexity consumption...
A green and efficient method has been developed to fabricate sulfonic acid-functionalized hollow acidic spherical catalysts with tunable shell thicknesses.
Research studies on zinc metal-based batteries have attracted considerable attention as a candidate for post-lithium-ion batteries. Zinc is one of the few metal anodes that compatible with aqueous and non-aqueous electrolytes, providing large theoretical capacity 820 mAh g–1. However, in anode suffers from hydrogen evolution reaction (HER), by which irreversibly consumed or corroded continually. Exact estimation corrosion rate has been challenge development Zn-based Measurement conventional...
Use of the chemotherapeutic agent cisplatin (CDDP) in cancer patients is limited by occurrence acute kidney injury (AKI); however, no protective therapy available. We aimed to investigate renoprotective effects Dendropanax morbifera water extract (DM) on CDDP-induced AKI. Male Sprague-Dawley rats (six animals/group) received: Vehicle (control); CDDP (6 mg/kg, intraperitoneally (i.p.); DM (25 oral); or + injection. treatment significantly increased blood urea nitrogen (BUN), serum creatinine...
S-methyl-L-methionine (SMM), also known as vitamin U, is commercially available skin care cosmetic products for its wound healing and photoprotective effects.However, the low permeation expected of SMM due to hydrophilic nature with a log P value -3.3, has not been thoroughly addressed.The purpose this study thus was evaluate effect enhancers on permeation/deposition SMM.Among tested in vitro deposition SMM, oleic acid showed most significant enhancing effect.Moreover, combination ethanol...
The objective of this study was to elucidate the effect hepatic damage on cisplatin (CDDP)-induced acute kidney injury (AKI). Thioacetamide (TAA, 150 mg/kg), a hepatotoxicant, intraperitoneally (i.p.) injected male Sprague-Dawley rats for 3 d prior CDDP (5 mg/kg, i.p.) injection. All animals were sacrificed 5 after treatment, and urine or blood obtained measure various parameters. No significant changes in serum alanine aminotransferase (ALT) aspartate (AST) activity observed treatment....
Disperse dyes containing a β‐sulphatoethylsulphonyl group have temporary solubility and can be applied for dispersant‐free dyeing of hydrophobic fibre. Six novel temporarily solubilised azo disperse having in their structures were synthesised, properties on polyester investigated. As dye intermediate, diazo component dibromo groups was prepared, 4‐diethylamino‐4′‐(2‐sulphatoethylsulphonyl‐4,6‐dibromo)azobenzene prepared by diazo‐coupling reaction. Then, the dicyano cyanation corresponding...
(1) Background: Robot-assisted laparoscopic prostatectomy (RALP) is preferred over open because it offers superior surgical outcomes and better postoperative recovery. The steep Trendelenburg position pneumoperitoneum required in prostatectomy, however, increase intracranial pressure (ICP). present study aimed to evaluate the effects of elevated ICP on quality emergence from anesthesia. (2) Methods: Sixty-seven patients undergoing RALP were enrolled. We measured optic nerve sheath diameter...
Abstract Gangliosides are a ubiquitous component of the membranes mammalian cells that have been suggested to play important roles in various cell functions such as cell–cell interaction, adhesion, differentiation, growth control and signaling. However, role gangliosides immune rejection response xenotransplantation is not yet clearly understood. In this study, differential expression patterns HEK293 (human embryonic kidney cells), PK15 (porcine NIH-kd (NIH-mini pig cells, primary cultured)...
가시광 통신(VLC: Visible Light Communications)는 넓은 스펙트럼을 가지는 가시광을 활용함으로서 기존 RF 통신과 비교하여 높은 전송속도를 달성할 수 있으며 주파수에 대한 규제를 적용받지 않는 차세대 통신기술이다. 본 논문에서는 DCO-OFDM 기반의 통신 테스트베드 구현에 대해 다룬다. OFDM은 멀티 캐리어를 활용한 방식으로서 심볼 간 간섭(ISI)을 낮춰준다는 특징을 가져 이를 VLC 시스템에 적용함으로서 VLC의 고유한 문제인 반사로 인한 멀티패스의 간섭과 간섭을 완화할 있다. 하지만 최대 전력 대 평균 비(PAPR)가 높으며 위상 잡음 및 주파수 오프셋에 취약하다는 단점이 PAPR 문제는 서브캐리어의 수와 변조 차수를 조정하여 있으며, 광학을 이용한 OFDM 시스템에서는 DC 바이어싱과 결합한 선형 스케일링 기법을 사용함으로써 추가적으로 완화시킬 OFDM을 효율적으로 결합하기 위한 기법, 동기화 심볼을 시간 파일럿 채널 추정등의 기술이 모두...
With the development of IT technology, a vast amount information, including articles, blogs and online comments, is being circulated in modern society.Much this data consists text, which unstructured constantly produced.As result, demand for analysis using text mining continues to increase by converting into new digitized data.Unlike mining, extracts patterns from structured data, biggest difference that looks text.A main purpose study examine how high-dimensional Korean variables, e.g.,...
벤튜리 스크러버는 여러 설비에서 다양한 물질들을 분리하기 위해서 사용된다. 최근 원자로 건물여과 배기계통(FCVS)에서의 활용이 새롭게 주목받고 있다. FCVS는 원자력발전소의 중대사고 시 건물 내부의 압력을 낮춰주는 역할을 한다. 그중 습식 방출 배관 후단에 스크러버가 설치되어 입자 및 에어로졸의 제거 효율을 증진시킨다. FCVS의 정확한 성능평가를 위해 스크러버의 역할 기능, 관련 연구 현황, 핵심 현상과 특성, 효율 계산의 수학적 모델을 검토하였다. 그 결과, 입자와 액적의 크기, 액적과 흡착률, 압력강하, 액막 형성 등이 주요 현상이고 계산에는 실험 상관식을 준용하여 사용하고 있음을 파악하였다. 현재 사용되는 계산 개발하여 다차원의 온도, 산도, 기체의 증기 분율 등을 고려한 모델이 필요하며 이를 향후 해석 코드에 반영하여 성능평가에 활용할 수 있을 것이다.
