This work incorporated a concept of local/global components based on the frequency-dependent detector adjoint function and a nodalization technique. The frequency-dependent detector adjoint functions presented by complex equations were expanded into real and imaginary parts. In the nodalization technique, the flux or detector adjoint function was expanded into polynomials about the center point of each node. The phase angles and the magnitudes of the two-energy group detector adjoint functions were calculated using a one-dimensional computer code. The calculations were made for a neutron detector located in the middle of the south core tank of the UTR-10 reactor. The reactor is located at Iowa State University. Results were compared with the exact analytical solution and were found to be within 2% of the values.ALAMMAR M, 1981, T AM NUCL SOC, V39, P955ALAMMAR M, 1981, THESIS IOWA STATE UANALYTIS GT, 1980, ANN NUCL ENERGY, V7, P351BENGHANAM M, 1983, THESIS IOWA STATE UBORELAND RJ, 1982, THESIS IOWA STATE UBURDEN RL, 1981, NUMERICAL ANALFEIZ M, 1983, THESIS IOWA STATE UFOWLER TB, 1967, ORNLTM4078 REPHENNESSY WJ, 1983, THESIS IOWA STATE UHUANG LR, 1980, T AM NUCL SOC, V34, P831KHERICHA ST, 1987, THESIS IOWA STATE UKOSALY G, 1971, ATOMKERNENERG/KERNT, V18, P203LEE SJ, 1981, T AM NUCL SOC, V39, P953LEE SJ, 1983, NUCL SCI ENG, V83, P427LUCIA A, 1973, ATOMKERNENERG/KERNT, V22, P1PAZSIT I, 1977, ATOMKERNENERG/KERNT, V30, P29PAZSIT I, 1978, ANN NUCL ENERGY, V5, P185PAZSIT I, 1980, ANN NUCL ENERGY, V7, P171PAZSIT I, 1983, NUCL SCI ENG, V85, P167PAZSIT I, 1984, NUCL SCI ENG, V88, P77ROBINSON JC, 1967, ORNL4149 REPROHACH AF, 1986, ANN NUCL ENERGY, V13, P549ROHACH AF, 1986, ANN NUCL ENERGY, V13, P57SANKOORIKAL JT, 1986, THESIS IOWA STATE USTEPHENSON SE, 1966, ORNLTM1401 REPVANDAM H, 1976, ATOMKERNENERG/KERNT, V27, P8WEINBERG AM, 1948, PHYS REV, V74, P851273EnglishArticleJPERGAMON-ELSEVIER SCIENCE LTDOXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD, ENGLAND OX5 1GBANN NUCL ENERGAnn.

They are amongst the most toxic mycotoxins and are produced predominantly by Aspergillus flavus and A. parasiticus. Pistachio is susceptible to invasion by aflatoxigenic Aspergillus species and subsequent production of aflatoxins, during preharvesting, processing, transportation or storage. Various methods have been used to detect toxin in pistachio such as chromatography (TLC and HPLC), ELISA and PCR base methods. Some of these methods e.g. chromatography, are time consuming, labor-intensive and expensive. In this study, nuts sample of pistachio were collected from pistachio orchards in Kerman, Rafsanjan and Isfahan. Culture media AFPA and PDA, were used to isolate Aspergillus species. Two hundred and fifty isolates were obtained and based on microscopic and macroscopic studies, the isolates belonged to the genera, Aspergillus, Fusarium, Rhizopus, Alternaria and Cladosporium. Comparing morphological characters of Aspergillus species grown on CYA, CY20S and MEA after one week, 10 following, Aspergillus species were identified:A. alliaceus, A. candidus, A. flavus, A. niger, A. niveus, A. ochraceus, A. parasiticus, A. tamari, A. terreus, A. unguis and A. wentii, that A. afflaceus, A. candidus, A. niveus, A. unguis and A. wentii, were reported for first time from pistachio in Iran. There was not a direct relationship between sclerotium and aflatoxin production in this study. Application of methylated B-cyclodextrin in culture media showed that it can be used for rapid detection of aflatoxigenic aspergilli.EnglishArticleJPREV2008001068691608-4306Q:\ISIS\1BOLOGICAL WARFARE\BIOSIS\BIOSIS_MISC1.txtBIOSISUNCLASSIFIEDPolish Journal of Environmental Studies20072007166807807-815Arkusz, J.Arkusz, J.Stepnik, M.Gutarowska, B.Gutarowska, B.Lewinska, D.Lewinska, D.Piotrowska, M.Piotrowska, M.Stanczyk, M.Stanczyk, M.Stepnik, M.Stepnik, M.

Evidence of mutagenic potential of some molds or their mycotoxins is still equivocal. Much more information is available for single mycotoxins or their metabolites than for complex mixtures composed of different fungi products.The aim of this study was to identify the mutagenic potential of extracts isolated from mold-attacked buildings using the mouse lymphoma assay (MLA).Although a thin-layer chromatography analysis of extracts isolated from test buildings showed the presence of well known mycotoxins (ochratoxin A and sterigmatocystin), the test extracts aswell as control extracts did not reveal mutagenic potential after 3-hr exposure without or with metabolic activation as tested with MLA. Negative results were also obtained after 24-hr treatment with every test sample in the absence of S9 fraction. The data indicates that extracts prepared from control and test buildings under experimental conditions did not induce mutations affecting the expression of the thymidine kinase gene in the cultured L5178Y TK+/- cells.EnglishArticleJPREV2008001061241230-1485Q:\ISIS\1BOLOGICAL WARFARE\BIOSIS\BIOSIS_MISC1.txtBIOSISUNCLASSIFIED
