In this paper, constructed a fractional polynomial spline to compute the solution of FDEs; the spline interpolation with fractional polynomial coefficients must be constructed using the Caputo fractional derivative. For the provided spline function, error bounds were studied and a stability analysis was completed. To consider the numerical explanation for the provided method and compared, three examples were studied. The fractional spline function, which interpolates data, appears to be useful and accurate in solving unique problems, according to the research.

The discovery of multi-lithotypes olistostromes deposits associated with potentially economically viable iron ore mineralizations in the Rayat region of NE Iraq are described in this study. The depositional and differentiation-classification characteristics of multi-lithotypes of olistostromes with distinct depositional and characteristics are reported here through detailed petrographic, mineralogical, and geochemical data, that allowed for mineralization mechanisms assessment and associated hydrothermal and alteration processes. Ferruginous conglomerate lithotypes occur below the sandstone olistostromes lithotypes section of the investigated series. Through the ferruginous conglomerate olistostromes (FCO) lithotypes there is a layer of potentially iron ore containing iron oxide (up to %42.55), quartz with some minor spinel content. Below the FCO, there are the horizons of (FOpO and FSO), they are also rich in hematite quartz and calcite with some minor spinel content. A 2m thick transition zone (TZ), separate poorly mineralized ophiocarbonatic olistostrome (OpCO) from the FCO. The multi-lithotypes of olistostrome from bottom to top are (serpentinite olistostrome (SO), Ophiocarbonatic olistostrome (OpCO), ferruginous serpentinite olistostrome (FSO), ferruginous ophiocarbonatic olistostrome (FOpCO), ferruginous conglomerate olistostrome (FCO), and sandstone olistostrome (SstO). In addition to Fe, the other potential economic importance element includes nickel (507 to 5816 mg/kg) and cobalt (47.2 to 328.3 mg/kg). The findings indicate that the Rayat olistostromes such as (SO, FSO, OpCO, FOpCO, FCO, and SstO) and the transition- zone (TZ) originated from a mixture of early hydrothermal alteration of serpentinites. The finding of olistostromes in the Rayat, exposes NE Iraq as a potential mineral-rich secto

The study deals with the upper contact of Qamchuqa Formation with the overlying Bekhme area of northern Iraq. This surface is characterized by presence of autobreccia bed including angular grains of (0.05_30cm in size) and composed of dolomite with disseminated black dolomite fragments which may indicates their subaerial exposure. Cementing materials filled the fractures and pores surrounding the breccias mostly are composed of saddle dolomite with dolomite crystal up to 3cm size that were formed late diageneticly by hydrothermal solution.

Thirty-one A. baumannii isolates were obtained from Shar and Burn hospitals in Sulaimani City, KRG-Iraq. Bacterial identification was confirmed by detecting both 16S rRNA and blaOXA-51 genes. The detection of carbapenem resistant isolates was carried out using Kirby- Bauer, RAPDEC Carba NP and combined disc assays. A high rate of drug resistance was observed, as 74.2% of the isolates were multidrug-resistant (MDR) and 38.7% were extensively drug-resistant (XDR), while carbapenem-resistant A. baumannii (CRAB) comprised approximately 58% of the isolates. Among CRAB isolates, carbapenemase production was detected by using the RAPDEC Carba NP and the combined disc assays in 88.8% (16/18) and 55.5% (10/18) of the isolates respectively. Phenotypic activity of efflux pump was detected among 22.5% of all isolates and 38.8% of CRAB isolates. PCR successfully identified the adeA, adeB, adeC, adeR, and adeS genes in 83.9%, 90.3%, 58%, 80.6%, and 90.3% of the isolates, respectively. Eight mutations in adeR and 15 mutations in adeS regulatory genes were recorded. We conclude that carbapenem resistance mechanisms in A. bumanni isolates included mutations in adeRS regulatory genes and production of carbapenemase.

A Detailed Calcareous nannofossil study conducted on the Bekhme Formation that is cropped out at the Southern limb of the Bekhere anticline, eastern ward of the Dohuk city near Bajlur village, northern Iraq. The Bekhme Formation is composed of marly limestone, Organic limestone and fossiliferous limestone. The nannopaleontological classification of these calcareous nannofossils led us to determine thirty-four genus/species belonging to nine families. The nannobiostratigraphic analysis suggested three calcareous nannofossils biozones from oldest to youngest are: (1) Quadrum sissinghii Interval Zone; (2) Quadrum trifidum Interval Zone; (3) Tranolithus phacelosus Interval Zone. These biozones suggest that the studied section from the Bekhme Formation is the Middle to Late Campanian, and it refers to temperature fluctuations which considered as possible warm time period at subtropical areas.
