BACKGROUND/OBJECTIVES Upon irradiation with visible light, the photosensitizer-peptide conjugate eosin-(KLAKLAK)2 kills a broad spectrum of bacteria without damaging human cells. Eosin-(KLAKLAK)2 therefore represents an interesting lead compound for the treatment of local infection by photodynamic bacterial inactivation. The mechanisms of cellular killing by eosin-(KLAKLAK)2, however, remain un...

Due to the superlinear dependence of leakage power consumption on temperature, and spatial variations in on-chip thermal profiles, methods of leakage power estimation that are known to be accurate require detailed knowledge of thermal profiles. Leakage power depends on the integrated circuit (IC) thermal profile and circuit design style. Here, we show that piecewise linear models can be used to...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

background and aims. with availability of hydrophilic sealers, drying of the canals before endodontic obturation is still a matter of debate. the aim of this study was to compare the apical micro-leakage of ah26, excite dsc, mta fillapex, and zoe sealers in dry and moist root canals. materials and methods. this experimental study was performed on 90 extracted maxillary central incisors. rotary ...

There is a demand for portable devices like mobiles and laptops etc. and their long battery life. For high integrity CMOS VLSI circuit design in deep submicron regime, feature size is reduced according to the improved technology. Reduced feature size devices need low power for their operation. Reduced power supply, reduces the threshold voltage of the device. Low threshold devices have improved...

Peri-implantitis is the main cause of implant failures. Peri-implantitis is provoked by the presence of bacterial infiltration around Implant-Abutment Connection (IAC). Reduction of bacterial leakage may be achieved by improving the accuracy and precision of the two pieces of IAC. The aim of the present in vitro study was to evaluate bacterial microleakage from the inside to the outside of the ...

Inhalation therapy using essential oils has been used to treat acute and chronic sinusitis and bronchitis. The aim of the present study was to determine the chemical composition of the essential oil of Artemisia capillaris, and evaluate the antibacterial effects of the essential oil and its main components, against common clinically relevant respiratory bacterial pathogens. Gas chromatography a...

The main purpose of this study is to analyze the current leakage of the power grid due to the change in speed of high-speed rail (HSR). First, using PSIM software as the fundamental basis, this study constructed an overall HSR circuit-based model system, including Scott transformer, auto-transformer, and the track equivalent circuit and grounding system. In addition, this paper sought to study ...

We propose a novel IDDQ outlier screening flow through a two-phase approach: a clustering-based filtering and an estimation-based current-threshold determination. In the proposed flow, a clustering technique first filters out chips that have high IDDQ current. Then, in the current-threshold determination phase, device-parameters of the unfiltered chips are estimated based on measured IDDQ curre...
