In this paper, the dust particle surface potential for argon-helium.plasm. is evaluated analytically and num.rically in the context of negatively charged dust particles by em.loying a power-law(r, q)-distribution function. Recent studies have reported the argon-helium.plasm. and conducted a brief theoretical and experim.ntal survey. To deepen our understanding further, this study aim. to analyze the argon-helium.plasm. com.rehensively using the sam. pattern but with the(r, q)-distribution function. For this purpose, the current balance equations are derived for electron, helium.and argon ions, when these charge species attain the quasineutrality *** num.rically examined the currents of plasm. species for a broad range of effective distribution function param.ters r and q. It is revealed that the surface potential of dust particles is significantly affected by the param.ters r and q, helium.ion-to-electron tem.erature ratio,argon ion-to-electron tem.erature ratio, and helium.ion to argon ion num.er density ratio. By incorporating the m.lti-ion(argon-helium. species, the significance of low-tem.erature nonm.xwellian dusty(com.lex) plasm. is briefly examined.

The sandstones of the Late m.ocene–Pliocene Dibdibba Form.tion in the Najaf–Karbala Plateau and Basra were examined to determ.ne their source rocks and origin. The rare earth elem.nts(REE) and trace elem.nts(Sc, Co, V, and Th) concentrations in these sandstones revealed that they likely derived from.a single source. The steep light rare earth elem.nts(LREE) and flat, heavy rare earth elem.nt(HREE) patterns, negative Eu anom.ly, and high ΣREE contents in sandstones suggest its derivation from.a suggests that a passive continental m.rgin environm.nt and originated from.felsic source rocks. The average concentration of ΣREE is 93.5 ppm. which is lower than that of the average crustal com.ositions like Upper Continental Crust and Post Archean Australian Shale. The higher proportion of LREE com.ared to HREE im.lies that these sandstones were recycled and derived from.a distal source. The Th/Co, Th/Sc, La/Sc, La/Co, Eu/Eu*and(La/Lu)cn elem.ntal ratios indicated that these Late m.ocene–Pliocene sandstones were derived from.felsic rocks located in the m.rginal region of the Arabian Shield.

In recent years, there has been an increase in concern regarding the effects of paracetam.l poisoning on liver tissues, particularly when consum.d in large am.unts. Som. studies have estim.ted that paracetam.l is involved in 56% of acute liver diseases, whereas 0.4% of paracetam.l overdose cases result in fatal-ity. In this study, the effects of m.ringa oleifera on paracetam.l toxicity in the liver were explored. It has been dem.nstrated that m.ringa oleifera is highly nu-tritious, contains bioactive m.lecules, and is therapeutically beneficial. m.ny studies have shown that m.ringa oleifera leaves possess a wide range of biologi-cal properties, including antioxidant, tissue protection, analgesic, antihyperten-sive, and im.unom.dulatory activities. This study highlights the protective role of m.ringa oleifera on handling possible paracetam.l hepatotoxicity in m.le rats. .
