Ciprofloxacin (Cip) and hydrocortisone (Hyd) were simultaneously measured as hydrochloride and sodium succinate, respectively, using the H-point standard addition method (HPSAM). The approach can precisely identify Cip in the presence of Hyd with various analyte-to-interference ratios (5:5, 5:10, 10:5, 10:10) µg.mL-1, in mixed samples containing (1-5µg.ml-1) of Cip, at the wavelengths of (236 and 257) nm. In the same way, Hyd was analyzed in the presence of Cip in different analytes with an interference ratio of (5:5, 5:10, 10:5, 10:10) µg.mL-1, in mixed samples containing (1-5 µg.mL-1) of Hyd, at wavelengths of (266 and 278) nm. The satisfactory results show good reproducibility of the developed method (RSD equals 0.9735-1.6825 and 0.9692-1.7671 for Cip and Hyd, respectively). The results also show that the excipients had no influence on the assaying of the above drugs (Recovery, 98.87–101.73). The recommended technique has successfully been used to determine the Cip and Hyd in pharmaceutical composites simultaneously with an RSD range of (0.972 to 1.671) and (0.898 to 1.820) for Cip and Hyd, respectively.
采用 H 点标准添加法 (HPSAM) 同时测定了盐酸环丙沙星 (Cip) 和氢化可的松 (Hyd)。在波长为（236 和 257）纳米的波长下，该方法可在含有（1-5µg.ml-1）Cip 的混合样品中，以不同的分析物与干扰物比率（5:5、5:10、10:5、10:10）µg.ml-1，精确鉴定存在 Hyd 的 Cip。同样，在含有（1-5µg.ml-1）Hyd 的混合样品中，以（5:5、5:10、10:5、10:10）µg.ml-1 的干扰比，在波长为（266 和 278）nm 的波长下，在 Cip 的存在下对不同的分析物进行 Hyd 分析。令人满意的结果表明所开发的方法具有良好的重现性（Cip 和 Hyd 的 RSD 分别为 0.9735-1.6825 和 0.9692-1.7671）。结果还显示，辅料对上述药物的检测没有影响（回收率为 98.87-101.73）。所推荐的技术已成功用于同时测定药物复合物中的 Cip 和 Hyd，Cip 和 Hyd 的 RSD 范围分别为 (0.972 至 1.671) 和 (0.898 至 1.820)。

The method of operational matrices based on different types of polynomials such as Bernstein, shifted Legendre and Bernoulli polynomials will be presented and implemented to solve the nonlinear Blasius equations approximately. The nonlinear differential equation will be converted into a system of nonlinear algebraic equations that can be solved using Mathematica®12. The efficiency of these methods has been studied by calculating the maximum error remainder ( ), and it was found that their efficiency increases as the polynomial degree (n) increases, since the errors decrease. Moreover, the approximate solutions obtained by the proposed methods are compared with the solution of the 4th order Runge-Kutta method (RK4), which gives very good agreement. In addition, the convergence of the proposed approximate methods is given based on one of the Banach fixed point theorem results.

In this paper, we define a cubic positive implicative-ideal, a cubic implicative-ideal and a cubic commutative-ideal of a semigroup in KU-algebra as a generalization of a fuzzy (positive implicative-ideal, an implicative-ideal and a commutative-ideal) of a semigroup in KU-algebra. Some relations between these types of cubic ideals are discussed. Also, some important properties of these ideals are studied. Finally, some important theories are discussed. It is proved that every cubic commutative-ideal, cubic positive implicative-ideal, and cubic implicative-ideal are a cubic ideal, but not conversely. Also, we show that if Θ is a cubic positive implicative-ideal and a cubic commutative-ideal then Θ is a cubic implicative-ideal. Some examples of the opposite direction of the previous theories are obtained.

Abstract Psoriasis is defined as a series of events that begins in its initial stage with dermatitis and then progresses to more widespread inflammation and increased oxidative stress. The aim of this study was to determine whether psoriasis and the levels of IL-15, IL-23, and TNF-α are related, the ELISA technique was used to detect the levels of inflammation in psoriasis patients and to compare them with healthy individuals. This study included 150 samples, including 90 patients with psoriasis and 60 healthy individuals, and the study was conducted from November 2021 to April 2022. The current study revealed that there was a significant difference in the level of TNF-α in the group of psoriasis patients compared to its level in healthy individuals. Also, there was a significant increase in the level of IL-23 in psoriasis patients compared to its level in the healthy individuals, while there was no significant difference in the level of IL15 between the two groups. However, the statistical study showed a positive and highly significant correlation between IL-15 and IL-23 levels in psoriasis patients, as well as the same relationship between IL-15 and TNF-α levels, in addition to a significant correlation between IL-23 and TNF-α levels in the group of patients. This shows that there is a clear association between these interleukins and psoriasis and its association with the inflammatory status of psoriasis patients, although there was no increase in the level of interleukin-15, the association of interleukin-15 with other inflammatory indicators proves its involvement in psoriasis and an indirect effect on the inflammatory state of psoriasis.

Azo dyes are the most common and widely used dyes, accounting for more than half of each year's dyes. In this work, a complete description of a new innovative series of compounds with the elements [Ag (I), Zn (II)] generated from the guanine azo dye ligand (GAB) 8-[1-(3-carboxy) azo] guanine has been studied. The structural formula was studied using several physicochemical analyses and spectroscopic techniques (FT-IR spectra, UV-Vis). The FTIR spectrum of the ligand (GAB) was compared to the spectra of the metal ion complexes formed to determine its identity. Chelating caused some changes in the spectra of the complexes to appear to demonstrate that they could be linked to the ligand. The complexes have a tetrahedral geometry shape, the ligand functions as a bidentate ligand, and thermogravimetric analysis (TGA) is used to measure the thermal stability of compounds. The findings and equation presented by the analytical data seemed to be in good accord with the conclusions of the thermogravimetric investigation, which demonstrated that the disintegration of the ligand (GAB) and its complexes occur in multiple steps. The configuration that follows weakens thermal stability: GAB(35.52%)>[Ag(GAB)(H2O)2]NO3.2H2O(34.6%)>[Zn(GAB)Cl2].H2O(31.54%), and the complexes have tetrahedral geometry shape. Furthermore, elemental analysis, mole ratio, and the mole ratio of each complex (1:1) (M:L). The ligand was effective as an acid-base indicator when the pH changed; they exhibited a striking color change, similar to how the ligand (GAB) and its complexes can be used to dye wool textiles due to their wide range of colors. It investigated how well the ligand (GAB) and its complex worked as a wool dye. The ligand GAB and its metal complexes were used to color most of the protein filaments in wool fiber, which have a complex structure with amino and carboxyl groups and colors ranging from orange to green.

The red palm weevil Rhynchophorus ferrugineus (Olivier, 1790), which belongs to the family Curculionidae, order Coleoptera, is one of the most important palm pests, which leads to heavy losses in date palms. In the last few years, it has been recorded in Iraq, from Safwan city south of Iraq, where it was detected on date palm trees (Phoenix dactylifera L, Arecales: Arecaceae). In the current study, specimens of adult weevils were collected from infested date palms (Phoenix dactylifera), that showed signs of infection in Safwan district, south of Basra province. The results of the investigation showed the presence of phoretic mites associated with the red palm weevil Rhynchophorus ferrugineus (Olivier, 1790). Two genera of Uropodid mites, deutonymph, were attached by anal pedicel to body parts of adult red palm weevils. They were collected and identified as Centrouropoda (Uropodidae), and Uroovbovella (Urodinychidae), according to accurate taxonomic keys. The differentiation between two genera of mites was studied. The deutonymphs were examined and photographed by an AM Scop camera installed on a light microscope, and the insects were photographed by a LEICA microscope. The infestation symptoms were illustrated with pictures.

Support Vector Machines (SVMs) are supervised learning models used to examine data sets in order to classify or predict dependent variables. SVM is typically used for classification by determining the best hyperplane between two classes. However, working with huge datasets can lead to a number of problems, including time-consuming and inefficient solutions. This research updates the SVM by employing a stochastic gradient descent method. The new approach, the extended stochastic gradient descent SVM (ESGD-SVM), was tested on two simulation datasets. The proposed method was compared with other classification approaches such as logistic regression, naive model, K Nearest Neighbors and Random Forest. The results show that the ESGD-SVM has a very high accuracy and is quite robust. ESGD-SVM is used to analyze the heart disease dataset downloaded from Harvard Dataverse.

SVM is typically used for classification by determining the best hyperplane between two classes. However, working with huge datasets can lead to a number of problems, including time-consuming and inefficient solutions. This research updates the SVM by employing a stochastic gradient descent method. The new approach, the extended stochastic gradient descent SVM (ESGD-SVM), was tested on two simulation datasets. The proposed method was compared with other classification approaches such as logistic regression, naive model, K Nearest Neighbors and Random Forest. The results show that the ESGD-SVM has a very high accuracy and is quite robust. ESGD-SVM is used to analyze the heart disease dataset downloaded from Harvard Dataverse.

The determination of captopril (CAP) using a new continuous flow injection analysis (CFIA) method was given in this work CAP in its pure state and some of its pharmaceutical preparations. The technique can be described as simple, fast, sensitive, easy to operate, and low-cost. The CAP reacted with ammonium ceric(IV) sulfate (ACS)2(NH4 )2SO4Ce(SO4)2. 3 H2O in an acidic medium and the reaction led to the formation of a white, slightly yellowish precipitate. The formed precipitate was studied using Ayah 6S×1-ST-2D Solar cell-CFI Analyzer, a through the reflection of accident light on the surfaces of the precipitate particles at (0-1800), expressed as the response of the transducer measured in (mV). Some chemical and physical parameters were studied to provide the optimal conditions for the study. The calibration curve within the range of (0.07-3.0) mmol/L was linear, with a correlation coefficient (r) value equal to (0.9983), and the percentage value of linearity (R2%) was (99.65). The method's detection limit (L.O.D.) of the new method was 272.5 ng/25 µL; it was calculated by diluting the minimum concentration in the calibration curve gradually. RSD% was less than 0.2% for 0.9, 1.5, and 3.0 mmol/L concentrations of C.A.P. for n=8. The method was successfully applied to estimate C.A.P. in three pharmaceutical preparations, each produced by a different company. The new method was compared with the UV-Spectrophotometric method (classical method) at λmax= 207.2 nm by using the method of standard additions. Both the t-test and the F-test were conducted to ensure that there wasn't a significant difference between the new method and the conventional one. The results of both tests showed, at a confidence level of 95%, that there was no significant difference.
