Micro-grids comprise low voltage distribution systems with distributed energy resources(DERs) and controllable loads which can operate connected to the medium voltage grid or islanded in a controlled coordinated way. This concept aims to move from "connect and forget" philosophy towards a full integration of DERs. Micro-grids can provide numerous economic and environmental benefits for end-customers, utilities and society. However, their implementation poses great technical challenges, such as a new philosophy in design of protection systems. In this work, a micro-grid protection scheme is presented based on positive-sequence component using phasor measurement units(PMUs) and a central protection unit(CPU). The salient feature of the proposed scheme in comparison with the previous works is that it has the ability to protect both radial and looped micro-grids against different types of faults with the capability of single-phase tripping. Furthermore, since the CPU is capable of updating its pickup values(upstream and downstream equivalent positive-sequence impedances of each line) after the first change in the micro-grid configuration(such as transferring from grid-connected to islanded mode and or disconnection of a line, bus, or DER either in grid-connected mode or in islanded mode), it can protect micro-grid against subsequent faults. Finally, in order to verify the effectiveness of the suggested scheme and the CPU, several simulations have been undertaken by using DIg SIlENT Power Factory and MATlAB software packages.

In Tunisia, five Bahloul spaced sections, Bargou, Jerisa, Guern Halfaya, Kherij and Gafsa were analyzed for biostratigraphy （foraminifera and radiolarians） and major and trace elements. This high-resolution biostratigraphic and chemostratigraphic integrated analyses for the late Cenomanian-Early Turonian Bahloul Formation provide new insight into the palaeoceanographic evolution of the southern Tethyan margin. Relative low abundance of related terrigenous Ti/Ai and K/ Al ratios and enrichment of some productivity proxies such as Ba, Cu, and Ni （organic matter related trace elements） suggests that the Bahloul, deposited during a relatively short period （0.5 Ma）, was of relatively elevated primary productivity and minimal detrital input. While higher D＊ values concurrent with lower Ti/AI ratios are interpreted as caused by enhanced fluvial material contribution, due to more humid climate during the OAE-2. Enhanced humidity triggered probably fluvial influxes, resulted in a sluggish water circulation and consequent anoxic/euxinic conditions favoring the preservation of organic matter at the bottom. Enrichments in redox-sensitive trace metals U, V, and Mo in the Bahloul Formation deposits and redox indices, such as V/（V＋Ni）, U/Th, V/Cr, and Ni/Co, indicate that oxygen-restricted conditions prevailed during the late Cenomanian to earliest Turonian times and correlate well with relative abundances of some foraminiferal and radiolarian paleo- environmental relevant indicators. High Ba~ values and Uauth may indicate anoxic conditions at least at the water-sediment interface during the Bahloul Formation deposition and provide information about low to moderate sulfate-reduction reactions.

Objective: To investigate the effect of pomegranate peel aqueous extract (PGE) on the development of secondary experimental echinococcosis and on the viability of Echinococcus granulosus protoscoleces, and the immunomodulatory properties of PGE. Methods: Swiss mice were inoculated intraperitoneally with viable protoscoleces. Then, PGE was orally administered daily during cystic echinococcosis development. Cyst development and hepatic damage were macroscopically and histologically analyzed. The production of nitric oxide and TNF-alpha was assessed in plasma and the hepatic expression of iNOS, TNF-alpha, NF-kappa B and CD68 was examined. Moreover, protoscoleces were cultured and treated with different concentrations of PGE. Results: It was observed that in vitro treatment of protoscoleces caused a significant decrease in viability in a PGE-dose-dependent manner. In vivo, after treatment of cystic echinococcosis infected mice with PGE, a significant decrease in nitric oxide levels (Plpha levels (Pline was strongly related to the inhibition of cyst development (rate of hydatid cyst growth inhibition=63.08%) and a decrease in CD68 expression in both the pericystic layer of hepatic hydatid cysts and liver tissue (Plpha and NF-kappa B expression was also observed in liver tissue of treated mice (Plusions: Our results indicate an antihydatic scolicidal effect and immunomodulatory properties of PGE, suggesting its potential therapeutic role against Echinococcus granulosus infection.

Objective: To evaluate the in vitro and in vivo effect of the Algerian propolis ethanolic extract(EEP) against Echinococcus granulosus(E. granulosus) infection. Methods: In vitro scolicidal activity of EEP was investigated on the protoscolices of hydatid cyst. This in vitro study was conducted by using an in vivo assay. BAlB/c mice were inoculated with E. granulosus and treated with propolis for three months. Hydatid cysts development was assessed. Nitric oxide(NO), tumor necrosis factor alpha(TNF-α) production and inducible NO synthase, NF-κB, and TNF-α spleen expression were estimated by Griess method and immunofluorescence ***: Our study revealed that EEP has a high scolicidal activity against E. granulosus. Oral administration of EEP decreased TNF-α, NF-κB and inducible NO synthase expression in the spleen tissues in the CE+EEP group, in comparison with the CE group. Concomitantly, EEP treatment caused an important systemic decrease in NO and TNF-α levels. These findings are associated with the reduction of CE development. Conclusions: This is the first report demonstrating with interest the antihydatic and immunomodulatory effects of the Algerian EEP, suggesting its therapeutic potential for the hydatid disease treatment.
