Epstein-Barr virus (EBV) belongs to the family of herpes viruses and about 90% of adults worldwide have antibodies against it. EBV infections are widespread in multiple patients with blood transfusion, such as ß-thalassemia patients, Hodgkin's lymphoma, Burkitt's lymphoma, and nasopharyngeal carcinoma.Blood samples from ( 70) thalassemic patients and (20) healthy controls were subjected for the detection of the blood groups (ABO) and EBV IgM antibodies by ELISA assay. The types of EBV infection as acute, late or reactivated were distinguished using a new immunoblot technique.The presentstudyshowedthat theEBV infection wasfound in (12.33 %) of patients with thalassemia and the highest incidence was (44.44%) in a class AB blood group subjects. Depending on Immunoblot techniquethetypeofinfections was distinguished, the results showed thatthehighestpercentage recorded was(55.55 %) in acuteinfections, followedby (22.22%) at late and reactivated infections.The present study found that thalassemia patients in Mosul / Iraq had a correlation between EBV and blood groups AB.

The process of energy efficiency improvement in any cellular network will require that the network design is densified to enhance higher spatial reuse while preserving the quality-of-service at the user. This study will analyze the combination of two densification techniques namely the small cell access point and the massive multiple-input-multiple-output (MIMO) base. The former is operator-deployed in the spatial soft-cell approach which is implemented after multiple transmitters which are in a system where noncoherent multi-flow beam forming is serving the users. In the study, the total power consumptions will be minimized to satisfy the QoS constraints. The technique has hidden convexity that will increase efficiency in the solution algorithms. This solution will promote exclusive assignments of users to the respective transmitters. The simulations in this research have promising results illustrating that the cumulative power usage can be significantly enhanced via the combination of the massive MIMO and small cell approaches. The results are viable for the optimal and low-complexity beam forming

Aspergillus(A) flavus cell contain the natural product cytochrome p450 enzyme, which is made up of from 400-500 amino acids and containing single heme group with single ferric ion, this enzyme destroyed by and reacted potentially with the used antifungal structures to yield new complexes with different electronic stability which related to the quality of the drug. The new complexes were studied by spectrophotometric technique. The theory on application it on the complexes indicated the following: low spin (LS) complexes with high crystal field stabilization energy (CFSE), octahedral shape and paramagnetic. Calculation and discussion pointed that the p450-triazole complex is the most stable and have higher stabilization energy. A flavus was grown on a carbon source formed from a combination of 1w:1w sucrose: fructose substrate to produce kojic acid by shake flask fermentation.The acid is detected and then identified by its physical properties as yellow crystalline material, odorless, melting point (m.p.) = 155-158(°C), lambda λmax=272nanometer (nm) in distilled water as pure solvent.
