In this study, we synthesized one azo compound (S19) and then condensat this compound with a carbonyl compound to give a Schiff base (S20) as the key step. The next step Schiff base reacted with some Amino acids and Anhydrides by cycloaddition reaction to give five-membered (S22, S23) and seven-membered (S21, S24) heterocyclic compounds. The chemical Structure for of the synthesized compounds were confirmed by using spectroscopic techniques (IR and NMR). In addition, tested their biological activity against Staphylococcus Aureus and Escherichia Coli displayed good activity.

Giardia lamblia, a protozoan parasite featuring flagella .and binucleation, is capable of infecting a diverse range of mammalian hosts. The incidence of human giardiasis, a veritable cosmopolitan pathogen, is most pronounced in developing nations.
The objective of the present study was to evaluate the impact of an infection caused by the Giardia lamblia parasite on iron levels and various hematological parameters in patients.
the study conducted between August 2022 and February 2023, blood samples were collected from people who were infected and non-infected with Giardia lamblia to evaluate the element iron and some blood indicators and the extent to which they were affected by infection. 60 blood samples (36 males and 24 females) were taken from people infected with Giardia, and 30 blood samples (15 males and 15 females) were taken from healthy people (controls). The infection was diagnosed by a direct smear and cultured in the laboratory. The control group underwent both clinical and laboratory examinations to confirm the absence of any disease.
The findings of the present investigation exhibit a noteworthy reduction in the average levels of serum iron (SI)., mean number of red blood cells (RBC), hemoglobin (Hb), and percentage of the packed cell volume (PCV) in people with the disease compared to healthy subjects, while a significant increase in the mean of the total number of white blood cells (WBC) was recorded in patients compared to healthy subjects.
Individuals with Giardia labmlia may exhibit notable changes in several hematological factors. Routine assessment of hematological factors is necessary for timely detection and effective treatment of giardiasis.

In this research, new mixed ligand complexes were prepared for complexes of some transitional element ions from the first transition series, which are: cobalt (II), nickel (II), and copper (II). The research included two paths:
First: The first path included the preparation of three polycyclic ligands derived from Isatin (L1, L2, and L3), all of these ligands were identified by measuring the melting point and infrared and ultraviolet-visible spectroscopy.
Second: The second path included the preparation of Mixed ligand complexes (L1and L2) with cobalt (II), nickel (II), and copper (II) ions. And Mixed ligand complexes (L1and L3) with ions of cobalt (II) and nickel (II). All the complexes of the new Mixed ligand were identified by the available analytical and spectroscopic methods. Based on the analytical data, the metal to ligands ratio was (1:1:1) and all complexes were characterized by various analytical techniques including (FT-IR and UV-Vis spectroscopy), CHN elemental analysis and determination using flame atomic absorption spectroscopy The percent magnetic susceptibility and molar conductivity of metal ions in the prepared complexes and these metal complexes dissolved in DMSO at a laboratory temperature of 1 × 10-3 M were also studied. by means of infrared (IR) spectra, and when compared to the spectrum of the free ligands, it was observed that some bands were displaced and others disappeared, or a change in shape and intensity occurred, which indicates a coordination occur between the metal ions and the prepared ligands. As well as the ultraviolet-visible spectrum. And detecting the presence of chloride ion inside or outside the coordination sphere. Depending on these obtained results, we were able to conclude that ligands of L1 and L2 behaves like a bi-chelate ligands, which led to the formation of mixed ligand complexes (L1, L2) with the proposed geometry of the proposed hexahedral symmetry in the presence of two chloride ions inside the coordination sphere. . Whereas, the L3 ligand behaved like a tetragonal ligand, which led to the formation of mixed ligand complexes (L2, L3) with the proposed geometry of the proposed hexahedral symmetry

Despite being unquestionable around 170 years ago and promising substantial ecological benefits and huge electrical capacity, fuel cells have just presented a serious potential for being commercially practicable. The solid oxide fuel cell has excellent potential and is currently an active research subject. The solid oxide cell might be apparatus composed entirely of solids that operate at very high temperatures, in contrast to other fuel cells. The challenges in developing a high-temperature solid-state fuel cell are discussed in this paper, as are the inorganic materials now employed and under checkup for such cells, as well as the challenges connected with running solid oxide cells on practical hydrocarbon fuels.

In this study, 4-chlorobenzodithioatebenzyltrimethylammonium and 4-methoxylbenzodithioatebenzyltrimethylammonium were synthesized and characterized by 1H-NMR, FTIR, UV-Visible and Mass techniques. Then they evaluated as corrosion inhibitors for carbon steel alloy (C1010) against corrosive environment of hydrochloric acid at different concentrations at 25 ˚C. both inhibitors revealed an excellent inhibition efficiency (97.95) % and (97.13) % at optimal concentrations (9) ppm and (8) ppm respectively. The effect of temperature on the corrosion was studied in absence and presence of the inhibitor, the raising of temperature leads to reduce the efficiency of the inhibitor and CR was enhanced. On the other hand, kinetic parameters such as activation energy , enthalpy of activation , entropy of activation and Gibbs free energy of activation were calculated which are insisted a physical adsorbed behavior for the inhibitor, an endothermic corrosion reaction whether in presence or in absence of the inhibitor and enhanced non-spontaneous behavior in presence of the certain inhibitor. Each one of the inhibitor has the mixed inhibition behavior.
