The synthesis of a new tridentate Schiff-base ligand and its metal complexes are reported. The reaction of ((2R)-4-methyl-2-((S)-(phenylamino)(p-tolyl) methyl) cyclohexan-1-one) with semicarbazide in a 1: 1 mole ratio resulted in the formation of the title ligand ((E)-2-((2S)-4-methyl-2-((R)(phenylamino)(ptolyl) methyl) cyclohexylidene) hydrazine-1-carboxamide)((HL). The reaction of the ligand with Co (II) and Ni (II), Cu (II), Zn (II) and Cd (II) ions in a 1: 1 (L: M) mole ratio gave the title complexes. Physico-chemical techniques were implemented, as required, to characterise the ligand and complexes. These include; elemental microanalysis, 1H, 13C-NMR and mass spectra, FT-IR and electronic spectra, magnetic susceptibility and conductance. These analyses revealed the isolation of octahedral, square planar and tetrahedral geometry about Co (II) and Cu (II); Ni (II); and (Zn (II), Cd (II)) ions, respectively. Thermal stability (TGA-DSC) of the ligand and selected complexes were also investigated. The antimicrobial activity of the ligand and its complexes against several bacterial strains and fungi species were examined. The collected data indicated that the complexes are more active against several kinds of organisms, under survey, compared with the free ligand.
The inhibitive action of Reactive Red (RR31) dye against corrosion of carbon steel in 1M acetic acid solution has been studied using gravimetric method at temperature ranged (288-318)K. The antibacterial activity for the different concentrations of RR31 dye against different bacterial species was studied. The experimental data indicates that this dye acts as a potential inhibitor for carbon-steel in acetic acid medium and the protection efficiency increase with increasing (RR31) dye. The adsorption of (RR31) dye on the carbon steel surface was found to follow Langmuir adsorption isotherm. Thermodynamic data for the adsorption process such as Gibbs free energy change ∆Gads, enthalpy change ∆Hads, and entropy change ∆Sads were estima

Many, and most of them take the desert road, Which traders had to endure the hardships of these roads from the insecurity, high winds and dust that sometimes destroyed the trade convoys, in order to obtain gold, which is one of the most important minerals that Ghana traded with various countries, in addition to the different goods that the merchants carried In particular, salt and its trade with Ghana, and also taxes, which were an important financial resource imposed by some gov

Show MoreThe present study was designed in the aquaculture and fish nutrition research aquarium in the College of Veterinary Medicine/Baghdad University from a period 1/3 to 1/6/2013 to investigate the toxicity of the herbicide glyphosate aqua on Barbus sharpeyi fish. Fish fingerlings were used with average weight between 10 – 15 gm to measure the (LC50), and 200 fingerlings were used to know the acute and chronic toxic effect for the herbicide. The fingerlings were randomly distributed as 10 fish for each aquarium. Fish were divided into four treatments and control group (without addition of herbicide). The first processing with a concentration of 0.415 mg/L for a duration of exposure 90 days, the second processing group with a concentration 0.
... Show MoreAllium ampeloprasum extract has the potential to facilitate wound healing due to its anti-inflammatory, antioxidant, and antibacterial properties. In this study, we aimed to investigate the potential wound-healing activity of the methanol extract derived from Allium ampeloprasum. Using 30 healthy male Wester rats; control group: 15 rats; normal saline applied locally instead of plant-extract. Experimental group: 15 rats received a daily local application of 200 mg/kg of the plant extract. Then, for each healing period of 0, 5, or 10 days, each group was divided into three-subgroups: A, B, and C, each with five rats. There was a significant difference in the percentage of wound contraction between the control and experimental groups (p 0.02)
... Show MoreHydatidosis is a sickness that affects human and farm animals. This disease is deemed as a public health problem in different regions of the world until nowadays. Surgical overlaps is the best way to treat the disease, while the risk of surgery lies in the possibility of cyst rupture and leakage of protoscolices and the recurrence of infection again, this prompted researchers to use scolicidal agents before surgery such as ethanol, plant extracts, to reduce parasite spread and recurrence of infection, recently researchers have been using nanoparticles as a scolicidal agent, like gold nanoparticles, silver nanoparticles, selenium nanoparticles, and others. This research aims to evaluate the fatal effect of zirconium oxide (ZrO2) nanoparticle

Samarra , where a study has 42 sample groundwater in different regions of the judiciary
randomly distributed all over the judiciary and examined in vitro.
The study showed that the quality of groundwater in the general area of study
Kipritateh punctuated Klordih water quality and other quality Bicarboonatih.
Varied the key components of groundwater in the study area in concentrations
between periods of rain and drought, especially because of the cation ion exchange processes
as well as mitigation as a result of filtering rain water and dominated the calcium ion,
followed by sodium.

The present work involved designing and synthesizing of a series of new. compounds which their molecules are composed from two biologically active components namely sulfamethoxazole or β-lactam containing drugs and cyclic imides. The target new compounds were synthesized by two steps in the first one a series of six bis (N-drug phthalamic acid_4-yl) ketone (1-6) were prepared from the reaction of sulfamethoxazole or β-lactam containing drugs with benzophenone 3, 3′, 4, 4′ -tetracarboxylic dianhydride.
In the second step, compounds (1-6) were introduced in dehydration reaction via fusion process producing the target compounds bis (N-drug phthalimidyl-4-yl) ketone (7-12). The antibacterial and antifungal high
