Abstract

The concept ofߩ-injective modules (where ߩ is a preradical) is introduced in this work as a generalization of injective modules. The definition of ߩ-injectivity unifies several definitions on generalizations of injectivity such as nearly injective modules and special injective modules. Many characterizations and properties of ߩ-injectivity are given. We study the endomorphisms rings of ߩ-injective modules. The results of this work unify and extend many results in the literature.طرحت في ھذا العمل كتعمیم للمودیولات ( − المودیولات الاغماریة )  مفھوم المودیولات الاغماریة نسبة الى جذر ابتدائي یوحد عدة تعریفات عن تعمیمات المودیولات الاغماریة مثل  الاغماریة. تعریف المودیولات الاغماریة نسبة الى جذر ابتدائي المودیولات الاغماریة تقریبا والمودیولات الاغماریة الخاصة. العدید من التشخیصات وخواص المودیولات الاغماریة نسبة الى جذر نتائج ھذا العمل توحد . قد اعطیت. درسنا حلقات التماثلات المودیولیة الذاتیة للمودیولات الاغماریة نسبة الى جذر ابتدائي  ابتدائي وتوسع العدید من النتائج الموجودة في المصادر.

Abstract

The present study were determined the concentrations of total petroleum hydrocarbon using spectroflurometer for sediment cores to eight sites ,six of them along Shatt Al-Arab estuary (Qurna,Dear, Kerma ,Ashar, Abo Al-Kasseb and FAO) in additional to two stations at Khor Al-Zubair and Um Qaser.Total petroleum hydrocarbons ranged (2.03-0.94) at Qurna, (8.8 to 1.2) al Dear, (9.22- 3.91 )at Kerma, (26.27-16.22) at Ashar, (18.54-3.7) at Abu Al-Kaseeb, (22.6-5.22) at Fao (6.75-0.96) at Um Qaser and (4.85-1.11) μg/g dry weight at Khor Al-Zubair The high average concentrations recorded in the Ashar (18.083) due to the presence of sources of oil pollution from the movement of boats and ships and the presence of oil refineries such as Al-Amuftih and Abadan which affected the areas, while the lower average were recorded in Qurna area (1.254) μg/g dry weight, because the sources of pollution where few or almost non-existent, where no industrial activities that cause pollution in the region in addition to being represented the confluence of the Tigris and Euphrates point and thus exposed to continuous washing. The analysis of the Total Organic Carbon were analyzed and high percentage recorded in Ashar (1.614%) and the lowest recorded in the Qurna( 0.658%). The Grain Size of sediment were also analyzed and the silt loam was predominate in most of the study areas.  ا ( وا  ت ا ') رة  ز ا ام    ا  ر  رو   ت ا  ا  وا  ا !"  س $  % ا  را  ا & و ' ، (1 ا  ر ، ا 7) ، ا 8 ، ا " ، ا 9 ( ا 5 ط ' &. ب) ا 34 (1" ل  ط *+ '" & *+ ,$ ا" ن .   ا ام E ام / E و8 " 0.94 ) - ( 2.03  ت ا  ر  رو   ا ;$ &< او  .، 1$ وام  ر ا > ?9@'" * ا A BC  و )  ا - ،( 26.27 " ف ام وزن E ام / E و8 " 3.91 ) - ،( 9.22 8 ف ام وزن E ام / E و8 " 2.1 ) - ،( 8.8 9 ف وزن (5.22 - ،( 22.6 (1 ا  ف ا ام وزن E ام / E و8 " 3.7 ) - ر ،( 18.54 7) ف ام وزن E ام / E و8 " 16.22 ) ام وزن E ام / E و8 " 1.11 ) - و( 4.85 1$ ف ام ام وزن E ام / E و8 " 0.96 ) - و( 6.75  ف ا ام وزن E ام / E و8 " !" ?@' ث ا  در ا 1" د  و * ا K ى ذ )8 ر ( 18.083 ) و 7) ا 9@'" ?A H 9A  ا ل )" *+ ا " ا ر ا > ف !" ح @8 " * ا A B ا 5 ط ' ه ا P ھ R S  ي P دان ا + و  ا *1 @' ا ?A 1 د ا  وو !U وارق وا  ا < ت " !"

Abstract

Fifty seven of bacterial isolates were isolated from different soils in different sites of Al Diwaniyah and Baghdad in Iraq using nutrient agar medium. The primary screening of bacterial isolates was done on nutrient agar by dropping a few drops of syringaldazine on bacterial colonies proved that, only 10 isolates were developed a pink color within 15 seconds. The secondary screening was done on nutrient broth using syringaldazine as enzyme substrate proved that the isolate 54 developed the highest sporebound laccase activity (12.8) U/ml. The biochemical tests of bacterial isolate with highest laccase activity showed that the bacteria are Bacillus subtilis. The optimization studies revealed that the maximum laccase production was achieved when the production medium were at the following conditions: 3 days of incubation, temperature 37 °C, pH 7.0, copper sulphate 0.2 mM, glucose as carbon source 3%, Tryptone as nitrogen source 0.2% , Kcl 1mM and pyrogallol 1mM as enzyme inducer , after these conditions the sporebound laccase activity was (439.23) U/ml.!" ا ام K7&'-L اق :C3 ا NO اد KQL و 4@R ا0+K3 ا ;8 456&78 IJ ا08 ;8 و 456&78 ب :. ;8 -<3=> ?. 4+:@&A13 ت ا (=C3 ا ;8 ن 0EFG و 4C1' ;8 ات :X23 ا YCL ط -2' إ +: ط ;> ي TQF3 ر ا -U( ا V' و ]6> ^F. 4+:@&A13 ات ا :FC&EF63 4@3 وW ا 46L:Q3 ي. ا TQF3 ر ا -U( ا V' و ^F. 4+0R-d3 ا 46L:Q3 ا -8 . ا 4@R-_ 15 ;8 bJcL ردي 03 ن ا 063 ت ا :< ت أظ (=> ان 10 ^&1_ أ 4+:@&A13 ات ا :FC&EF3 ا ]6> syringaldazine V1.:F3 ا ?+=R( ا ;8 4@3-CO ]6> ا : Bacillus h 4+0@p0F@A3 رات ا -1&G( ا 4X' ا0L =@h%3 ج ا -&Rn 4@3-CO ]6> ذات أ 4+:@&A13 ا 43=C3 ا j@7k. ?. 12.8 ). ) U/ml رات 01E3-L Ns@r رو K@ ھ ?J:L ارة 37 و :p 4r رKL م و -+ ة 3 ا KF3 ;tu3 ا Ks> ^R-h =@h%3 4@r-&R إ ]6> ن أ cL ت :< أظ ]6dF3 وف ا :i3 ا 4' درا . subtilis ;@r و:&@s63 ر KzFh ن 0&1+:. ن ( 3%) و 0L ر-A63 راً Kz8 ز 0h06h ل) و 08 N68 س ( 0.2 -us3 ت ا -&+:1h ;8 : ]6> وي -p V' و NO 7 KCL رات 01E3-L V1.:F3 ا =@h%3 ا 4@3-CO ^R-h . و =@h%3 =5uFh ل) 08 N68 ل ( 1 03-r و:+-13 ل) و ا 08 N68 م ( 1 0@'-.013 ا K+ ر06h %0.2 ) و )

Abstract

Day after a day, the increase of heavy metals concentration in the riverine water have dramatically attired anthropogenic activities. Scientist and policy makers in India gave serious attention for the rising level of pollutants and changes in mid-stream water quality of Ganga River. The present investigation was attempted to study water quality of river Ganga and to record the quantitative change in heavy metals in water if any during the three consecutive months of sampling in 2013. A systematic study has been carried out to assess the impact of heavy metal concentration on water quality of river Ganga in Varanasi city. 36 water samples from four sampling stations i.e. By pass bridge upstream, Assi Ghat, Dashswamedh Ghat, and Raj Ghat bridge downstream, were collected and analyzed for Temperature, pH, concentrations of Cr, Ni, Cu, As, Cd, Pb in (μg.L-1). The results from this study indicated significant accumulation of these heavy metals in the riverine water. The order of heavy metals accumulation in the riverine water was As > Pb > Cu >Ni > Cr > Cd. The analytical data indicates that all heavy metals studied are found to be in excess than the prescribed limit in some water samples of the study areas as compared to World Health Organization standards (WHOS) and toxicity reference value (TRV) for fresh water proposed by USEPA except Ni.*+, ا . 1*23! ا 45! ت ا !.1! ا 7*8  9/ رة درا 4<= و >*# ?@A / ر &BC ه ا / EF *-G! دن ا .! ا I+?9 داد I م 4 $.= /4 O% ! ا ?&B ى ?Q/ EF ه ! ا 84B EF ة ?> ! ات ا ?R2! ت وا @4*! ى ا 42(/ ع 19 ار 7*8 '&/2 وا اھ I+ ر $%&! ا EF ار ?-! ا E.BM ء و *.! ا EF ات ?R2! ى ا 42(/ ه و *! 84%! ات ا ?R2! س ا ) ل UV W/ O% ! ا ?&B EF ه ! ا 84B '-2! ! و5/ E ھ !5! ا # را $! ة. ا ?> ! ا X2 ھC ?&B ه / 7*8 _2%/ # اء درا ?0 ا '9 ( 2013 ). %(! ط، اذار) >Y ، EBG! ن ا 4B+ ( ?&Y ا @U@ ل UV Z@$[ E2! ا *-G! دن ا .! ا I+ ا?9 ان $0 ه. و U8 رة ا 4+`! ا %$! ا EF ?&%! ى ا ?Q/ ل 4 ط 7*8 1*23/ ت a5/ b= ار W/ ذج 4B ( 36 ) `V وا $%&! رس ا %= %$/ EF O% ! ا 0 ودر e/5! ا F?.! ذج %! ا f*59 '9 .( As > Pb > Cu >Ni > Cr > Cd) ZB+ ?&%! ه ا / EF *-G! دن ا .! ا '+ ا?9 d9?9 ZB+ ت a5! اg.= W/ ذة 4Vh! ا # رو $! ا *-G! ا ?M%.! ا I+ ا?9 ان # را $! ل ا UV W/ W>9 . 1*23! ا *-G! ا ?M%.! ا I+ ا?9 ارة و ?5! ا . !8 &= ح 4(! ا .0?! ا -! وا !.! ا 5
