- FULLERENE-LIKE STRUCTURES IN COALS
Abstract: Anthracites are considered as raw materials for the production of fullerenes, and the radiospectroscopymethod is proposed for express diagnostics of carbonic materials. In this work the features of the influence exerted by sizes, forms, and structures of anthracite samples on EPR signals are studied. It hasbeen demonstrated that the features of the recorded EPR spectra for the coals exhibiting high degreesof metamorphization are associated with high concentrations of the localized spins at the recordingconditions and also with the peculiarities of their spatial-temporal localization within the fullerene-likestructures of the coals.

- Study of Electronic Structure of Boron-Nitride /Graphene Bilayer by Using
DFT
Abstract: In this work, we study the electronic structure (number of open channels (NOC), band structur(BS), densityof states (DOS), and I-V curve) of boron nitride/ graphene sheet using SIESTA and GOLLUM codes. Abinitio structural optimization performs for all structures using the local density approximation (LDA) withnorm-conserving pseudopotentials, double zeta polarized (DZP) basis sets of pseudoatomic orbitals, andthe Ceperley-Alder exchange correlation functional with the atomic forces relaxed to 0.02 eV/˚A. Threetypes of simulated heterostructures sheets have been studied: 1- One graphene strip and one boron nitridestrip sheet. 2- Two graphene strip and one boron nitride strip sheet. 3- Three graphene strip and one boronnitride strip sheet. We show that there is a dramatic reduction in energy gap ‘Eg’ of heterostructurescomparing with the insulator boron nitride (Eg 4.6 eV) and increasing in energy gap comparing withsemimetallic graphene (zero gap).

Abstract: The present study is concerned with isolation and identification of some aquatic fungi,including its species of Saprolegnia in the waters of Al-Diwaniyah province and molecularcharacterization. The study is regarded as the first in Iraq according to the information available tous. Two species, Saprolegnia parasitica and Saprolegnia ferax, have been isolated from rivers,lakes and fish. The physical and chemical environmental characteristics have been measured. Thetypes above have been examined to extract the DNA. The (PCR) technique has been used toexamine the presence of proteases enzyme. The results of isolation and identification showed that the percentage of the two types were64% in rivers areas 40% in the lakes areas and 50% in fish. The rates represented the examinedsamples which were 60 samples. The S. parasitica species is more apparently found during(February, 2014), the number of samples was 12, the less presence of this species in (April, 2014),where the number of sample, was 3. The S. ferax species is more apparently presented in(February, 2014), the number of samples was 10. The less presence was in (April, 2014), thenumber of samples was 2. The results showed that the number of isolation of Saprolegnia speciesin study area was 6 in rivers, 2 in lakes, and 3 in fish. The second species, S. ferax showed number of isolations which were 10 in rivers, 8 in lakes,and 2 in fish. The PCR examination has used to detect the rDNA gene which responsible for proteases geneand whether it is found in the two species of fungi. The express way has been used to extract DNAand according to the instructions of manufacturer company. The concentrations of DNA in firstspecies were 121.8-73.0 mcg/microliter and purity 1.87-1.80 .In the second species theconcentrations ofDNAwere 2360.4-166.9 mcg/microliter and purity 2-1.75. The standard rateaccording to the instructions of company is 1.8, this has been measured by using the NanodropSpectrophotometer and reading the absorbing with wave length 260-280 nm and the efficiency ofmethod used and molecular confirmation for fungi species and the determination of fungi speciesaccording to the sources of fungi isolation, which one of them is more spread in the study area andwhich one is more infections for fish. The S. parasitica species was less spread in rivers withpercentage of 66.6%. And the percentage of the in lakes and fish was 100%. The second speciesS.ferax was more spread in rivers with percentage of 70%.The percentage of the in lakes 62% andfish was 100%. The results, by using PCR technique, showed that the percentage of protease in first specieswas 25% in rivers. In lakes and fish was 100% .Concerning the second species, the percentage ofenzyme was 42% in rivers, 40%in lakes, and 50% in fish. It can be concluded that there is a diversity in fungi species with respect to study areas andenzyme secretion in the stages of fungi infection. The enzyme is more apparently found inS.parasitica species compared with S.ferax species.
