Abstract

Adding inverter-based renewables to harmonically distorted distribution systems without proper planning may lead to power quality issues, harmonic overload, overvoltage, and overheating equipment problems. Thus, the hosting capacity of the system must be controlled and enhanced so that it does not exceed the threshold value, to prevent these problems. In this paper, the enhancement of the hosting capacity of a harmonically distorted distribution system is achieved by harmonic mitigation. A damped double-tuned filter (DDTF) is utilized to reach this goal while operating the system within its acceptable operating limits according to IEEE 519 standard, the Egyptian electricity distribution code, the system voltage limitations, the transmission line thermal capacity, and the permitted power factor threshold values. A newly developed multi-objective optimization technique, namely multi-objective artificial hummingbird optimization algorithm (MOAHA), is employed to design the DDTF to maximize harmonic-constrained hosting capacity (HCHC), minimize the system active power losses, and satisfy the pre-mentioned set of operational constraints. The results prove the superiority and effectiveness of the suggested HCHC enhancement technique.

AbstractWebsite

The innate and adaptive immune systems fail to control HCV infection in the majority of infected
individuals. HCV is an ssRNA virus, which suggests a role for Toll-like receptors (TLRs) 7 and 8 in
initiating the anti-viral response. Here we demonstrate that HCV genomic RNA harbours specific
sequences that initiate an anti-HCV immune response through TLR7 and TLR8 in various antigen
presenting cells. Conversely, HCV particles are detected by macrophages, but not by monocytes and
DCs, through a TLR7/8 dependent mechanism; this leads to chloroquine sensitive production of proinflammatory
cytokines including IL-1β, while the antiviral type I Interferon response is not triggered in
these cells. Antibodies to DC-SIGN, a c-type lectin selectively expressed by macrophages but not pDCs
or mDCs, block the production of cytokines. Novel anti-HCV vaccination strategies should target the
induction of TLR7/8 stimulation in APCs in order to establish potent immune responses against HCV.

We present the experimental realization of plasmonic hyperdoped Si nanocrystals embedded in silica via a combination of sequential low energy ion implantation and rapid thermal annealing. We show that phosphorus dopants are incorporated into the nanocrystal cores at concentrations up to six times higher than P solid solubility in bulk Si by combining 3D mapping with atom probe tomography and analytical transmission electron microscopy. We shed light on the origin of nanocrystal growth at high P doses, which we attribute to Si recoiling atoms generated in the matrix by P implantation, which likely increase Si diffusivity and feed the Si nanocrystals. We show that dopant activation enables partial nanocrystal surface passivation that can be completed by forming gas annealing. Such surface passivation is a critical step in the formation of plasmon resonance, especially for small nanocrystals. We find that the activation rate in these small doped Si nanocrystals is the same as in bulk Si under the same doping conditions.

AbstractWebsite

The distribution of hepatitis C virus (HCV) genotypes among Egyptian patients positive for anti-HCV was determined and their influence, when combined with neu-oncoprotein overexpression, on the development of hepatocellular carcinoma (HCC) was examined. The study groups included asymptomatic carriers (ASC) and patients with chronic active hepatitis (CAH) and HCC. HCV genomes were detected in the sera of 27 ASC, 29 CAH and 33 HCC patients known to have HCV infection defined by EIA and recombinant immunoblotting techniques (Inno-LiA) as well as by reverse transcriptase (RT)-PCR. The HCV genotype was determined by a reverse hybridisation technique (Inno-LiPA I and II), whereas neu-overexpression was detected by the Oncogene Science EIA Kit. Eighty-nine patients were eligible for HCV genotyping; 75 patients (84.3%) were infected with a single genotype, including 1a in 11 patients (12.4%), 1b in 2 patients (2.2%) and 2a in 10 patients (11.2%). Genotype 4 (a or c + d) was detected in 51 patients (57.3%) and only one patient had genotype 10a (1.2%). Fourteen patients (15.7%) showed mixed infection; eight of them had 1a + 4 (a or c + d) and four had 2a + 4 (a or c + d); the remaining two cases had 1a + 2a and 1b + 2a. The results revealed an increased incidence of genotype 4 in CAH and HCC patients in comparison with ASC. There was also a significant overexpression of neu-oncoprotein in CAH and HCC patients compared with ASC, which was significantly associated with subtype 4 infection. The results suggest that infection with subtype 1a and 4 HCV may be considered a risk factor for the induction of neu-overexpression and subsequent development of HCC.

BACKGROUND: There are eight genotypes of hepatitis B virus (A-H) and subgenotypes are recognized. Genotyping can be accomplished based on a partial sequence of HBV genome such as the pre-S or S gene. Several methods have been developed and used for HBV genotyping. This study was undertaken to determine the HBV genotypes in Egyptian pediatric cancer patients with acute and chronic liver disease.

METHODS: HBV genotypes were determined in 22 patients who had acute forms of liver disease (AH) and in 48 patients with chronic active hepatitis (CAH). A type-specific primer based the nested-PCR method was employed in the HBV genotyping.

RESULTS: This study showed that HBV infections in pediatric cancer patients are attributed predominantly to viral genotypes D and B that constituted 37.1% and 25.7%, respectively of the total infections. In addition, there was a relatively high prevalence of mixed infections of 15.7% among the studied group especially mixed A/D genotype infections. Genotype D was found significantly more often in patients with CAH than in patients with AH [23/48(47.9%) v 3/22 (13.6%)].

CONCLUSION: These findings show the distribution of HBV A-D genotypes in pediatric cancer Egyptian patients. Furthermore, our results indicate a markedly high prevalence of mixed A/D genotype infections in subjects with CAH and a possible association of mixed infections with the severity of liver diseases.
