Methotrexate (MTX)is a multiple therapeutic drug, it's used in treatment of ectopic pregnancy, neoplastic disease, autoimmune disorders, and inflammatory conditions. It’s associated with a spectrum of side effect that includes damage to the (liver, kidney, lung and bone marrow). MTX has been associated with fetal malformations in( nervous, skeletal, gastrointestinal, and cardiac) system, and even fetal death. The study was conducted to test the effect of two doses of MTX (5and 10mg/kg) on the development of the mice liver during two gestational age (day11 and day 17) of pregnancy.18 healthy female mice were divided into three groups ,first group (control) was injected with normal saline ,second group injected with 5mg/kg and third group injected with 10mg/kg (all groups were injected on day 7 of gestation). Histology examination of control fetal liver on day11of gestation showed normal fetal development where cords of hepatoblast were formed and hepatic blood sinusoids were filled with erythroblasts ,fetal liver of animals dosed with 5mg/kg and 10mg/kg on day 11 of gestation showed ballooning degeneration with hepatoblast that have pyknotic nucleus .control fetal liver of day 17 of gestation showed normal hepatocyte arranged around a central vein, fetal liver of animals of day 17 of gestation dosed with 5mg/kg showed ballooning degeneration while fetal liver of 17 days of gestation dosed with 10mg/kg showed ballooning degeneration with inflammatory infiltration. Results of this study revealed that low dose MTX can affect internal organs causing damage during gestational age which might cause problems later in life after birth ,the effect have been proven in mice but does not necessarily apply on human but a possibility of such damage in human should be kept in mind.

A factorial experiment (2× 3) in randomized complete block design (RCBD) with three replications was conducted to examine the effect of honeycomb selection method using three interplant distances on the vegetative growth, flowering, and fruit set of two cultivars of bean, Bronco and Strike. Interplant distances used were 75× 65 cm, 90× 78 cm, and 105× 91 cm (row× plant) represent short (high plant density), intermediate (intermediate plant density), and wide (low plant density) distance, respectively. Parameters used for selection were number of days from planting to the initiation of first flower, number of nodes formed prior to the onset of first flower, and number of main branches. Results showed significant superiority of the Strik

In this paper, the Reliability Analysis with utilizing a Monte Carlo simulation (MCS) process was conducted on the equation of the collapse potential predicted by ANN to study its reliability when utilized in a situation of soil that has uncertainty in its properties. The prediction equation utilized in this study was developed previously by the authors. The probabilities of failure were then plotted against a range of uncertainties expressed in terms of coefficient of variation. As a result of reliability analysis, it was found that the collapse potential equation showed a high degree of reliability in case of uncertainty in gypseous sandy soil properties within the specified coefficient of variation (COV) for each property. When t

The (NiTsPc) thin films operating by vacuum evaporation technique are high recital and good desirable for number of applications, were dumped on glass substrates at room temperature with (200±20nm) thickness and doped with Al at different percentage (0.01,0.03) besides annealing the sample with 200˚C for 1 hours . The stimuluses of aluminum dopant percentage on characterization of the dropped (Ni Ts Pc) thin films were studied through X-ray diffraction in addition from the attained results, were all the films have polycrystalline in nature, as well the fallouts of XRD aimed at film illustrations polycrystalline, depending on the Al ratio doping, the results, SEM exposed the surface is regularly homogeneous. Utilizing first-ideolog

This research aims to study the effect of different pH values on the growth of CdTe nanoparticles during specific times. The reflux method has been used as a method for preparing CdTe quantum dots. A difference in absorbance and intensities of peaks at pH 10.5 and 11.5 was observed during the reaction period. The growth rate of the NPs (nucleation) was irregular at low pH values. Optical examinations showed that the best growth rate of NPs was at pH value 12.

This research studies the effect of addition of some nanoparticles
(MgO, CuO) and grain size (30,40nm) on some physical properties
(impact strength, hardness and thermal conductivity) for a matrix
blend of epoxy resin with SBR rubber. Hand –Lay up method was
used to prepare the samples. All samples were immersed in water for
9 weeks.
The Results showed decreased in the values of impact strength and
hardness but increased the coefficient of thermal conductivity.
