SYNTHESIS, CHARACTERIZATION AND SCREENING OF ANTIMICROBIAL ACTIVITY FOR SOME NEW SCHIFF BASES AND THIAZOLIDINONE DERIVATIVES DERIVED FROM AROMATIC CARBOXYLIC ACID
...Show More Authors

In this study, the antimicrobial properties of newly synthesized Schiff bases (4a-4e) and thiazolidinone compounds (5a-5e) generated from 3,5-dinitrobenzoic acid were assessed. These compounds were obtained by reacting 3,5-dinitrobenzoic acid (1) with ethanol in a few drops of concentrated H2SO4 to produce the ester (2). The acid hydrazide (3), which was produced by treating the ester with hydrazine hydrate, reacted with the proper aldehydes, including 4-bromobenzaldehyde, 4-chlorobenzaldehyde, 4-hydroxybenzaldehyde, 4-methoxybenzaldehyde, and 4-hydroxy-3-methoxybenzaldehyde, respectively, to form Schiff bases (4a-4e). The thiazolidinone compounds (5a-5e) were produced by the cyclocondensation reaction of compounds (4a-4e) with thioglycolic acid. A variety of techniques, including mass spectroscopy, 1H NMR, 13C NMR, and FT-IR, were employed to find novel compounds, which exhibited mild antibacterial activity against four kinds of bacteria according to the biological results. The effectiveness of the thiazolidinone derivatives against Candida albicans was mediocre. The compounds showed stretching absorption bands at 1625-1639 cm-1, belonging to azomethine groups, and the amine-induced loss of absorption bands at 3392, 3311 cm-1. Schiff bases exhibited singlet signals at δ (8.33-8.87) ppm for azomethine groups and signals at 150.67-150.75 ppm for carbon by 1H NMR and 13C NMR. Thiazolidinone compounds showed stretching absorption bands at 1701-1708 cm-1 due to the lactam ring carbonyl group. The signals at (170.99-171.19) ppm are affording to the carbon carbonyl group of the lactam ring for thiazolidinone compounds. For citation: Abbas Z.M., Rumez R.M.

Nutritional Value of White Button Mushroom (Agaricus bisporus) Which is Most Widely Consumed in kurdistan regin-iraq
...Show More Authors

This study was conducted in 2018, at Technical College of Applied Sciences, Sulaimani Polytechnic University, and Kurdistan Region-Iraq. The aim of the study was to determinate nutritional compositions and some elemental contents in marketable white button mushroom (Agaricus bisporus) that is collected in local markets of Kurdistan Region-Iraq. Five different samples (A: Penjwen product fresh, B: Sulaimani product fresh, C: American caned, D: Valencia Netherlandcaned and E: Erbil product fresh) were collected to be observed. The elements were analyzed by Atomic Absorption Spectrometry methods, and their chemical compassions were determined, too. The collected data were analyzed by One Way ANOVA. The highest fat, protein, fiber and dry matte

Population Dynamics of the Terrestrial - Isopod species Armadillidium vulgare Latrielle , 1804 in AL - Jadriyia District -Baghdad - Iarq .
...Show More Authors

The Present Work includes the study of the population dynamics of Armadillidium vulgare in AL- Jadiriya region in Baghdad. Monthly samples were collected using a quadrat 0.0625 m2 from November 2007 to November 2008.. The population density of A.vulgare, ranged from 880 ind/m2 in May to251 ind/m2 in January respectively. This species showed high aggregation dispersion in the study area. The sex ratio showed that the number of females were more than that of males and significantly differd (P < 0.05) during the reproductive months. Furthermore, it was found that the juveniles of species were present at most time of the year, But the large sized groups have been observed during summer and spring. And showed a positive linear correlations betwe

This study aimed to investigate the role of Big Data in forecasting corporate bankruptcy and that is through a field analysis in the Saudi business environment, to test that relationship. The study found: that Big Data is a recently used variable in the business context and has multiple accounting effects and benefits. Among the benefits is forecasting and disclosing corporate financial failures and bankruptcies, which is based on three main elements for reporting and disclosing that, these elements are the firms’ internal control system, the external auditing, and financial analysts' forecasts. The study recommends: Since the greatest risk of Big Data is the slow adaptation of accountants and auditors to these technologies, wh
