We present a detailed study of the ionization fraction of the Barnard 68 pre-stellar core, using millimeter HCO and DCO lines observations. These observations are compared to the predictions of a radiative transfer model coupled to a chemical network that includes depletion on grains and gas phase deuterium fractionation. Together with previous observations and modelling of CO and isotopologues...

The effect of camellia oil on the permeation of flurbiprofen (FP) and diclofenac sodium (DFS), used as model drugs, through rat and pig skin was examined. Two different types of camellia oil were used: one of them was purified by distillation and the other was purified by filtration without heating. The distilled camellia oil (DCO) and the filtered camellia oil (FCO) were applied to the skin as...

New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic and docosahexaenoic (EPA and DHA, respectively). The present study investigated the use of an EPA+DHA oil derived from transgenic Camelina sativa in Atlantic salmon (Salmo ...

T-cell tolerance to tumor antigens represents a major hurdle in generating tumor immunity. Combined administration of agonistic monoclonal antibodies (mAbs) to the costimulatory receptors CD134 plus CD137 can program T-cells responding to tolerogenic antigen to undergo expansion, and effector T-cell differentiation, and also elicits tumor immunity. Nevertheless, CD134 and CD137 agonists can als...

Precoder Design to Improve Performance of Multi-User OQAM DCO-FBMC Underwater Visible Light Communication

Abstract Mixed reality applications often require virtual objects that are partly occluded by real objects. However, previous research and commercial products have limitations in terms of performance efficiency. To address these challenges, we propose a novel depth contour occlusion (DCO) algorithm. The proposed method is based on the sensitivity binocular stereoscopic vision device. In this me...

<p>VLC technology is one of the most promising technologies in generations communications, especially 5G after significant development optical semiconductors, specific laser diode, and use FBMC modulation system. DCO-FBMC surpasses all disadvantages DCO-OFDM techniques, as it characterized by high speed large bandwidth, but this technique consumes energy when converting a real bipolar sig...

This paper focuses on certain manufacturer hidden areas of a hard disk, specifically Host Protected Areas (HPA) and Device Configuration Overlays (DCO). These areas can be problematic for computer forensic investigators, since many of the common industry tools cannot detect the presence of the HPA and DCO. A review of the ATA specifications and recent white papers indicate that these areas can ...

In this paper, a low power implicit type pulsed flip-flop (PFF) using self-driven pass transistor logic is presented. The pulse generation logic comprising of two transistor AND gate is used in the critical path of the design for improved speed and reduced complexity. The pass transistor logic driven by generated clock pulse is used directly to drive the output of the flip-flop. The proposed de...

Antibiotics resistance development in European hospitals has increased alarmingly in recent years. To counteract this danger, a semantic web based IT solution is proposed which intends to integrate the access to relevant clinical data repositories from different European hospitals. This endeavor relies on formalized and shared models of the clinical domain. We describe the development process o...
