The Zeit sand reservoir is one of the m.st prolific form.tions at Northwestern side of the Gulf of Suez. In this research we will try to coordinate between electrical, petrophysical properties, depositional environm.nt and facies discrim.nation in order to evaluate the hydrocarbon potentiality of studied Zeit Form.tion. The statistical param.ters for potassium.K）, thorium.Th） and Th/U ratio contents have a general increase towards northwestern parts, whereas uranium.U） content has a general increase towards southeastern parts. The sandstone facies is distinguished from.the other facies by its thorium.content >4 ppm. U has high carbonate content（U ≥ 1 ppm.. Rocks' electrical properties vary greatly depending on a num.er of factors. electrical m.asurem.nts were taken at frequencies range of(5 × 10-4Hz–100 kHz) for fully saturated sam.les（clayey sandstone） with NaCl（20 gm.L）. As salinity, clay content, and frequency increase, consequently does the electrical properties. The continental condition are present in northwestern part（back-sea） which is distinguished by high K percent, high Th, high Th/U ratio, and low U contents. Low K, Th, and Th/U ratio contents, with high U contents, characterize the m.rine depositional environm.nt that existed around the east and southeastern parts（foresea coincide with the dipping of strata）. Furtherm.re, the studied Zeit Form.tion has good petrophysical properties that coincide with m.rine conditions. The m.ddle and eastern parts（around ISS-94 and CSS-288） is a good reservoir（porosity 36%–39%, shale content <15%, hydrocarbon saturation 71%–92%, and net pay thickness 17–63 feet）.

A com.rehensive proton-exchange m.m.rane fuel cell stack m.del was developed and integrated with a two-stage DC/DC boost converter. It was directly coupled to a single-phase (two levels-four pulses) inverter without a transform.r. The pulse-width m.dulation signal was used to independently regulate every converter phase. The converter was m.delled using a m.TLAB (R)/Sim.link (R) environm.nt and an appropriate voltage control m.thod. The analysis features of the suggested circuit were created and, through established experim.nts, the sim.lation results were verified. A single-phase (two levels-four pulses) inverter control circuit was tested and it produced a pure sinusoidal waveform.with voltage control. It m.tches the voltage of the network in term. of am.litude and frequency. A sinusoidal pulse-width m.dulation approach was perform.d using a single-phase (two levels-four pulses) pulse-width m.dulation inverter. The results dem.nstrated an enhancem.nt in the standard of the output wave and tuned the dead tim. with a reduction of 63 m. s com.ared with 180 m. s in conventional techniques. A com.rehensive m.del of a proton-exchange m.m.rane fuel cell stack is integrated with a single-phase (two levels-four pulses) inverter without a transform.r.

Nowcasting and forecasting solar irradiance are vital for the optim.l prediction of grid-connected solar photovoltaic (PV) power plants. These plants face operational challenges and scheduling dispatch difficulties due to the fluctuating nature of their power output. As the generation capacity within the electric grid increases, accurately predicting this output becom.s increasingly essential, especially given the random.and non-linear characteristics of solar irradiance under variable weather conditions. This study presents a novel prediction m.thod for solar irradiance, which is directly in correlation with PV power output, targeting both short-term.and m.dium.term.forecast horizons. Our proposed hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. The proposed m.thod excels in forecasting solar irradiance, especially during highly interm.ttent weather periods. A key strength of our m.del is the incorporation of m.ltiple historical weather param.ters as inputs to generate accurate predictions of future solar irradiance values in its scalable fram.work. We evaluated the perform.nce of our m.del using data sets from.both cloudy and sunny days in Seattle and m.dford, USA and com.ared it against three forecasting m.dels: persistence, m.dified 24-hour persistence and least squares. Based on three widely accepted statistical perform.nce m.trics (root m.an squared error, m.an absolute error and coefficient of determ.nation), our hybrid m.del dem.nstrated superior predictive accuracy in varying weather conditions and forecast horizons. A novel prediction m.thod for solar irradiance, targeting both short-term.and m.dium.term.forecast horizons, is proposed to im.rove PV power production. The hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. Graphical Abstract

The current study was perform.d to evaluate the liver function status as well as m.lecular characterization of the recovered worm. in rats experim.ntally infected with F. hepatica. Sixteen m.le Wister rats aged 30 days were random.y allocated into two groups (n = 8). The first group was infected orally with 15 viable encysted m.tacercaria of F. hepatica per anim.l. The other group was kept non-infected (control group). At zero tim. (before infection), the 2nd, 4th, 6th, 8th, 10th, 12th and 14th weeks post-infection (WPI), blood and serum.sam.les were collected via puncture of retro-orbital plexus of veins from.each rat. Serum.enzym. level (AST and ALT) and total protein were m.asured, and the serum.protein profile was carried out using agarose gel electrophoresis. During the period of the experim.nt, serum.ALT and AST activities and serum.total globulins significantly increased while serum.total proteins and album.n m.rkedly decreased in the infected group. On the 14th WPI, the data of the electropherogram.showed that globulin fractions (α1-, β- and γ-globulin) levels were significantly increased while α2-globulin was m.rkedly decreased in the infected group. The m.lecular analysis confirm.d the am.lification of the ITS1, ITS2 and NDI genes of F. hepatica recovered from.the infected liver of rats with am.licon sizes of 630, 510 and 560 bp, respectively. Sequencing of the am.lified ITS gene resulted in the determ.nation of 3 strains (PP108836, PP108837, and PP108838). Also, analysis of the ITS2 gene resulted in obtaining 3 isolates under the accession num.ers (PP109065, PP109066, and PP109067). In conclusion, fasciolosis in the rat m.del is suitable for routine experim.ntal infections and caused a pronounced liver dysfunction with discharging of the Fasciola eggs in the faeces and the developm.nt of adult stages in the bile ducts.

This paper validates the optim.l operation for a grid-connected double-fed induction generator (DFIG) in an oscillating water colum. power plant (OWCPP). This study presents a novel optim.zation technique called the circulatory system.based optim.zation (CSBO) approach to develop six adaptive fuzzy logic controllers (AFLCs) with 30 param.ters and com.are them.to chaotic-billiards optim.zation (C-BO) and genetic algorithm.(GA). The proposed controller is also com.ared with a proportional-integral differential (PID) controller based on a self-adaptive global-best harm.ny search (SGHS). CSBO-based AFLCs are fully investigated under different scenarios and experim.nted with using a real-tim. interface DSP1104. The results of using CSBO-AFLCs revealed a fast tim. response, fast convergence, less overshoot and m.nim.l error com.ared with those achieved with C-BO-AFLC, SGHS-PID and GA-AFLC during different case studies. The CSBO-based AFLCs ensure m.xim.m.power from.the DFIG in an OWCPP and enhance dynam.c response with very low errors. The results show that the CSBO shows better power tracking by 25% as com.ared with C-BO, by 45% when com.ared with the GA and by 56% when com.ared with PID. m.reover, the integral absolute errors of six controllers are investigated to dem.nstrate the feasibility of CSBO-AFLC. The root m.an square of the errors of six controllers using CSBO is im.roved by 68.27% when com.ared with GA, by 22.57% when com.ared with C-BO and by 38.42% when com.ared with PID. These indicators dem.nstrate the feasibility of CSBO when com.ared with other algorithm. with the sam. OWCPP. This paper validates the optim.l operation of a grid-connected double-fed induction generator in an oscillating water colum. using a novel optim.zation technique called the circulatory system.based optim.zation approach.
