In an effort to highlight the role of digestion and maceration methods to determine the strength of antibacterial effect and phytochemical elements of coriander seeds aqueous and methanolic extracts. Five concentrations (20, 40, 80, 160 and 320 mg/ml) of four extracts (aqueous by maceration, aqueous by digestion, methanolic by maceration and methanolic by digestion) were utilized against five clinically isolated bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aerogenosa and Acenitobacter baumani), and compared with ciprofloxacin and cefotaxime discs as control. Agar well diffusion technique was employed to clarify the antibacterial activity of the extracts' concentrations relaying on quantifying the diameter of inhibition zone (IZ) in millimeter. The bioactive chemical compounds of four extracts were specified by means of conventional systems. In the main, all extracts inhibited the growth of every bacterial species starting from (80) mg/ml concentration, forming IZs' with various measurements that their expansion was drawing upon the rising of extracts' concentrations. The IZs that proceeded from (160, 320) mg/ml concentrations were larger than that come out from cefotaxime. The maceration extracts declared their embracement of alkaloids, and their impact were vigorous compared with the extracts of digestion which marked by comprising the tannins and flavonoids in aqueous and methanolic extracts one by one. The most susceptible bacterium to ethanolic extracts was S. aureus. It could be benefiting from coriander seeds for treatment of bacterial infections through extraction the best active phytoconstituents by using both of suitable extraction technique and solvents together. .

A simple, rapid, accurate and precise spectrophotometric method is proposed for the determination of atenolol in both pure form and in its pharmaceutical formulation. The method is based on the oxidation of atenolol with chromate in acidic medium of 1N H2SO4, the residual amount of oxidizing agent is then reacted with indigo carmine dye in the presence of oxalate as a catalyst, the increase in the absorbance of the dye, which is proportional to the amount of the determinants atenolol is then measured at 610 nm. Beer's law is obeyed in the concentration range of 30-1500 µg/25 ml with a molar absorptivity of 0.73×104 l.mol-1.cm-1, Sandell's sensitivity index of 0.364 μg.cm-2, and a relative standard deviation of ± 0.263 to ± 0.376% depending on the concentration level. The limit of detection (LOD) and limit of quantification (LOQ) are 0.3259 and 1.0863 μg ml−1, respectively. The proposed method has been applied successfully to the determination of atenolol in pure and pharmaceutical preparation..

This paper presents a way to mitigate the influence of temperature effects on the equilibrium point (Q-point) of vertical cavity surface emitting lasers (VCSELs) by investigating the effect of laser injection current (Iinj) and dc-bias level (Ibias) numerically using MATHCAD software. Results show that, by changing temperature 50 oC (i.e. from 10 to 60) with Iinj = 3Ith and Ibias = 0, the photons density (P(t)) has decreased from 1.636 × 1016 cm-3 to 0.733 × 1016 cm-3, the carrier density (N(t)) has increased from 2.367 × 1018 cm-3 to 2.669 × 1018 cm-3 and the laser output power (Pout) has decreased from the 2.366 mW to the 1.025 mW. In contrast, by increasing the Iinj from 3Ith to 5Ith and the Ibias from 0 to 1.5Ith, the rate of the decreasing in the P(t) and in the Pout have reduced more than 25%. %25.

At this paper, an experimental investigation was conducted to explore the effect of different curing methods and water cement ratios on compressive strength and density of normal weight concrete. The samples had been submitted to five different curing methods including: water curing (standard curing), air curing and three types of colored plastic bags curing including (Transparent, white and black bags). The effect of w/c ratio on compressive strength at different curing had been studied too. Test results shows that the curing by plastic bags gives accepted results compared with standard curing and better than air curing. For all kinds of referenced curing the increasing in w/c ratios decrease the compressive strength, and the density of concrete samples reduces at air and plastic bags curing compared with standard curing..

The study is carried out on twenty shale samples that were collected from the Kolosh Formation (Paleocene – Early Eocene) within the Dokan area at northeastern part of Iraq. The samples were subjected to laboratory studies including chemical analyses for origin rock characterizing source rock composition, paleo-weathering conditions and tectonic. The origin rock compositions were evaluated mainly based on Al2O3/TiO2, TiO2/Zr ratios and a TiO2 and Al2O3bivariate. The result suggest predominantly intermediate igneous source rock of the Kolosh Formation shale’s. The bivariate plot, of (K2O/Na2O) and (SiO2), (MgO+Fe2O3 %) and (TiO2%), as well as the refashion ships based on the elemental components (Co ,Th, Sc, Zr, La) were used to reveal tectonic setting of the depositional basin. All Kolosh Formation shale’s samples were in Oceanic Island Arc. CIA values, bivariate plot of (SiO2%) and (Al2O3+Na2O3+K2O)% and ) (Al2O3- CaO+Na2O- K2O) %compositional space of the shale samples were utilized to infer the chemical maturity and the pale weathering conditions of the Formation. The results shows that Kolosh shale samples represent lower degree of chemical weathering of origine rock which imply semi-arid climatic conditions. .

The kinetics and thermodynamics of the removal of Alzarin yellow and Congo red dyes from their aqueous solutions using local clay taken from Shoraw region northwest of the province of Kirkuk - Iraq as well as bentonite and activated charcoal as adsorbents was held, using UV- visible spectroscopy to follow the adsorption process. The equilibrium time of the adsorption process was determined and found that it reached a state of equilibrium in a period of time between 70-50 min, in the case of adsorption of the dyes on the activated charcoal and bentonite surfaces and 70-60 min, when using the clay. The results indicated that the best weight of the adsorbent surfaces is (0.1gm). Adsorption was studied in the natural pH of the basic dyes, as well as in the acidic and neutral pH. Isotherm (Freundlich and Langmuir) was used, and it was found that the best isotherm is Freundlich. Adsorption efficiency was calculated in the range of 15-65 oC of temperature. It was found that the adsorption efficiency decreased by increasing the temperature in the case of alizarin yellow dye adsorption on the three surfaces. Whereas the adsorption efficiency of Congo red on the clay surface decreased by increasing the temperature and this indicates that the reaction is exothermic. It has been found that the efficiency of adsorption is increased by increasing the temperature in the case of adsorption of Congo red dye on activated charcoal and bentonite surfaces and this indicates that the reaction is endothermic. The values of the thermodynamic parameters of the adsorption process and the adsorption kinetics study were calculated and found that the adsorption follows the pseudo- second order equation..
