This study estimated seven heavy metals (Fe, Cu, Zn, Pb, Ni, Cd, Cr) in water (dissolved and particulate phase), sediments and some aquatic organisms including two species from aquatic plants (Ceratophyllum demersum&Phragmites australis); one species of clam (Psedontopeses euphratics) and two species from fish (Oreochromis aureus& Leuciscus vorax)in four sites within Mashroo AL- Musayyib channel project/ branch of Euphrates river, Babylon , medial of Iraq . This aims to show the concentration of these elements, their fate and the mechanisms of their transmission through the food chain in this lotic aquatic system ; also in addition to examining some physicochemical properties of river water such as water temperature (WT),air temperature (AT),pH , electrical conductivity ( EC) , salinity ,total dissolved solid ( TDS), total solid suspended (TSS) , dissolved oxygen (DO) and biological oxygen demand ( BOD5) .The occurrence in heavy metals in water was found in the order in the Dissolved phase :- Zn> Fe > Cu> Ni>Pb> Cr > Cd, the zinc element recorded the highest rate in site two for spring season while the cadmium element recorded the lowest rate in site one for spring season. In the particulate phase:- Zn> Cu >Fe > Ni>Pb> Cr > Cd, the zinc element recorded the highest rate in site two for spring season while the cadmium element recorded the lowest rate in site four for spring season. The sediment order was Zn> Cu >Fe >Pb> Ni > Cd > Cr where the zinc element recorded the highest rate in site two for spring season where as the chromium element recorded the lowest rate in site two for spring. In aquatic plant the order was in C. demersum :Zn> Fe > Cu>Pb> Cr > Ni > Cd, the zinc element recorded the highest rate in site four for winter season while the cadmium element recorded the lowest rate in site one for autumn season. In P. australis: Zn> Fe > Cu>Pb> Cd > Ni > Cr , the zinc element recorded the highest rate in site two for spring season while the chromium element recorded the lowest rate in site two for spring season. In clam the order was: Zn> Fe > Cu> Ni >Pb> Cd > Cr where the zinc element recorded the highest rate in site two for spring season while the chromium recorded the lowest value in site 3 through winter 2021.In fish species (O. aureas) the order was Fe > Zn > Cu>Pb> Cr > Cd > Ni. The iron element recorded as the highest rate in site 2 in spring 2021 whilethe element that recorded the lowest rate was Ni in site 2for spring in L. vorax. The iron element recorded the highest rate in site one for summer season where as the Nickel was recorded a lower value in site four in spring2021.
Industrial wastewater containing nickel, lead, and copper can be produced by many industries. The reverse osmosis (RO) membrane technologies are very efficient for the treatment of industrial wastewater containing nickel, lead, and copper ions to reduce water consumption and preserving the environment. Synthetic industrial wastewater samples containing Ni(II), Pb(II), and Cu(II) ions at various concentrations (50 to 200 ppm), pressures (1 to 4 bar), temperatures (10 to 40 oC), pH (2 to 5.5), and flow rates (10 to 40 L/hr), were prepared and subjected to treatment by RO system in the laboratory. The results showed that high removal efficiency of the heavy metals could be achieved by RO process (98.5%, 97.5% and 96% for Ni(II),

The extracted insecticide from the polluted samples with these insect from air, soil, and the leaves of trees, have be used into the reaction with H2O2 and benzedine. The kinetic study of this reaction was formed in basic medium,( pH= 8.6), using UV. Spectra at (?= 420nm). The study showed that the reaction is the first order, and the speed of the reaction was used to estimate the concentration of insecticide in solution and mixture. The experiments of this study indicated that this method has the speed and efficiency for quantitatively estimating these

The experiment has been carried out in the Syrian National Commission of Biotechnology, during the growing season 2018/2019, to study the effect of abiotic stresses (salinity and osmotic stresses) on the activity of some antioxidant enzymes and biochemical traits in Catharanthus roseus. The experiment has been laid according to (CRD) with three replications. The seeds have been sterilized by NaOCl solution (0.5% v/v), then planted on MS medium. Plantlets have been moved to MS medium enriched with NAA (1 mg.L-1) and BA (2 mg.L-1). The callus has been initiated from leaves using MS medium containing NAA (1 mg L-1) and KIN (2 mg.L-1). After 60 days, callus

Aim of the present study was to determine the levels of GLP-1 and GPCR in non- diabetic dyslipidaemic patients and compare the results with the control group, which may be used as a novel biomarker to predict heart disease in these patients. The study was also aimed to find the relationship between GLP-1 and GPCR with lipid profile and glucagon in the patient group.

Abstract
The Verbal Violence that is directed towards sons is considered one of
the dehavioural problems that have negative reflections on the personality
of the individual . the increase in the frequency and intensity of that
behavior in the daily life may lead to psychological and behavioural
disturbances, and such behaviourhas to be stooped in an early time before it
leave negative affects on the personality of the teenager which will not be
cured or removed easily .
The family that is represented by the parents has a prominent effect In the
shaping of the teenager's personality , hence forth the normal teenage is
a reflection of a stable family life , relatively empty of disturbances and
