The present study was designated to estimate the histological effect after administration of cold watery
fenugreek seeds extract of the nephron in albino mice. This work was carried out on 40 healthy adult mice aging (6-8
months). The experimental animals was divided into four treated groups (A, B, C, D) and control group. Preparation the
watery fenugreek seeds extract for administration with (150 mg/g) of concentration. The experimental animals treated
with extract for different time periods as the following (15, 30, 45, 60 days). The histological results of the treated groups
show after the following time periods [A after(15) days, B after (30) days, C after (45) days and D after (60) days of
administration]. The histological results showed the nephrons composed of renal corpuscle, proximal convoluted tubules,
Henelʼs loop, and distal convoluted tubules, the current results appears that the renal corpuscle composed of tuft of tinny
capillaries glomerular surrounding by double layer called Bowmans capsule which contain between two layers occur
main space that called Bowmans space, so showed the mesangial cells occupied the spaces between the glomerular
capillaries. The glomerular capillaries had significant increase in diameter. The proximal convulated tubules, lined by
simple high cuboidal epithelial cells with more prominent brush border, the tubules characterized by significant increase
in diameter. The present study Henelʼs loop notification the epithelial layer of internal surface of lined with simple
squamous epithelial and acidophilic cytoplasm. The tissue section appears that the nephron composition characterized by
significant increase in diameter with increased the time periods of administration of extract for the treated groups which
showed exfoliated cells that aggregation in the lumen on tubular structures of the nephron. The extract have significant
effect on the depression of height the epithelial cells lining of the internal surface of the proximal, henel loop, and distal
convoluted tubules that associated with increased time of administration of extract which led to increase the glomerular
infiltration rate that led to increase the amount of infiltration inside the tubular structures of the nephron in addition to
increase the speed the infiltration flow .

This study was aimed to detection of pork contamination in commercial canned meat product in Iraq market
using real-time PCR method through analysis of mitochondrial cytochrome b gene. Method based on porcine-specific
primers and TaqMan probe were designed to amplify 130 bp for assessing pork adulteration in canned meat. Testing the
twenty samples of local market that show no pork detection to have pork contamination in nineteen meat cans. In
conclusion, specific PCR amplification of cytochrome b gene is useful in detection of hidden pork meat mince in
processed foods because of its rapid, specificity and sensitivity. This method will ensure that trust of the customers
with these products.

The survey compares the three common arrays using in 2D imaging surveys, Wenner, Wenner-Schlumberger and Dipoledipole
electrode arrays, and most suitable array is chosen in Uruk archaeological site. The Comparison consist of the resolution and
efficiency of 2D resistivity imaging survey with these arrays. Three survey tests on a selected profile in Uruk archaeological site are
done to examine the imaging capabilities of these arrays.The survey shows that the Dipole-dipole array has better horizontal data
coverage than the Wenner. The horizontal data coverage for the Wenner-Schlumberger array is slightly wider than Wenner array but
narrower than that obtained with the Dipole-dipole array. Also, the survey time for survey Dipole-dipole array longer than the
others, then that for Wenner- Schlumberger, then at the later that for Wenner array. The survey shows that the Dipole-dipole array
has a shallower depth of investigation compared to the Wenner and Wenner –Schlumberger arrays.Finally, it shows that Dipoledipole
array gives the highest resolution and best image for vertical anomalies. During the 2D resistivity imaging in Uruk, Dipoledipole
array is found to be the best array compared to Wenner and Wenner- Schlumberger arrays for detecting archaeological
targets.

The potential energy surfaces of the five-ring bent-core molecules with a central 1,3-phenylene unit,
including azobenzene with alkyloxy as terminal chains, has been investigated by using density functional theory
(DFT). The PBE1PBE/6-31G(d,p) level of theory has been used for some computations in addition to the BP86
function, where used to study the influence of rotation of the connection groups. These computations were performed
on the conformational behavior of the connection groups, included ester linkage group, N=N group and terminal OR
group, of the five-ring bent-core compound in a systematic way. The relaxed rotation barrier with respect to
the six torsion angles (φ1, φ2, φ3, φ4, φ5 and φ6) were calculated. It is interesting to note that the oxygen atoms of the
linkage group, which are directly connected to the rings, give banana-shaped compounds with energy barrier by about
0.9 kcal mol-1 and high flexibility, whereas the ester group connected to phenyl ring by a carbon atom shows a high
energy barrier by about 10.2 kcal mol-1 and a relatively limited conformational degree of freedom. The dependency of
the Dipole moment on conformers with constraints to the torsion angle was studied.

A new, simple, sensitive and rapid spectrophotometric method is proposed for the determination of
trace amount of palladium (II). The method is based on the formation of a 1:1complex with 3-(4′- antipyriyl azo)
1- nitroso-2-naphthol (APANN) as a new reagent is developed . The complex has a maximum absorption at
436.5 nm and εmax of 0.19 x105 L. mol-1. cm-1. A linear correlation (0.1–2.0 μg. ml-1) was found between
absorbance at λmax and concentration.

An analytical procedure has been carried out to measure the charge that may trapped in an insulator sample and
related electrostatic surface potential in sense of mirror effect phenomenon. In fact, scanning electron microscope mirror
method (SEMME), sometimes called electron mirror method (EME) and/or magnification factor method (MFM), has been
used to accomplished that purpose. However, this work has been carried out concerning the theoretical point of view, the
mirror plot curve has been adopted as an evaluation scale for the quality of the mirror image. Therefore, this procedure had
been used to investigates the experimental mirror plot curves for PMMA material with different accelerating potential and
studying the most important parameters that affects in these curves. Results have clearly shows that the radius of irradiated
area play an important rule in the shape of mirror plot figure and then the quality of the image.
