Synthesis and Spectroscopic Characterization of a New Series of Benzo[E][1,3]Oxazepine Compounds from Schiff Bases
No full textThe present work includes synthesis, characterization and investigation the biological activity of a new series of benzo [e][1, 3]oxazepine compounds which were prepared from Schiff bases. The synthetic routes have been divided into two steps as follows: The first step includes the synthesis of Schiff bases, by treatment of 4-amino diphenyl amine and different substituted benzaldehydes in absolute ethanol using glacial acetic acid as catalyst. The second step of this work is the synthesis of a series benzo [e][1, 3] oxazepine, by the reaction of the synthesized Schiff bases with phthalic anhydride in dry benzene. The structures of the synthesized products were confirmed on the basis of (UV-Visible, FT-IR, 1H-NMR, 13C-NMR spectroscopy. Some of the synthesized compounds were evaluated for antibacterial activity, against two types of bacteria, Staphylococcus aureus (Gram positive) and Pseudomonas aeruginosa (Gram negative).The results showed the high sensitivity of the synthesized compounds to both types of bacteria
Synthesis and Antimicrobial Activity of Some New Thiazolidin-4-one Derivatives of 4-(6-methylbenzo[d]thiazol-2-yl)benzamine
No full textA number of derivatives of 2-(substituted phenyl)-3-(4-(6-methylbenzo[d]thiazol-2-yl)phenyl) thiazolidin-4-one (3a–j) have been synthesized from the reaction of 4-(6-methylbenzo[d]thiazol-2-yl)benzenamine(1), with different substituted benzaldehydes (2a–j), followed by cyclocondensation reaction of the prepared imines with 2-meraptoacetic acid in high yields. Furthermore, the structures of the newly synthesized compounds were confirmed by FT-IR, 13C-NMR,13C-DEPT, and 1H-NMR spectral data. The imines and thiazolidin-4-one derivatives were evaluated for their antibacterial activity against Escherichia coli as gram negative and Staphylococcus aureus as gram positive, the results have shown significant activity against both types of bacteria
Synthesis and Spectroscopic Identification Of A New Series Of Biologically Active 2-Iminothiazolidine-4-One Derivatives
No full textA series of 2-amino-5-(substituted phenyl) 1,3,4- thiadiazol have been synthesized through the reaction of thiosemicarbazide with substituted benzoic acids in the presence of phosphoroxy chloride readily undergo nucleophilic addition – elimination reaction with chloroacetyl chloride in benzene as a solvent to afford 2-chloro acetamido compounds. The prepared compounds were subjected cyclization reaction and results in the formation of a series of 2- imino-3-(substituted phenyl) 1,3,4- thiadiazol-2yl-thiazolidinone -4 one . The IR ,1H and 13C- NMR spectra of the prepared compounds were confirmed to their proposed structures . Finally antimicrobial activity of the newly obtained compounds were tested against Klepsilla pneumonia (gram -ve ) and Staphylococcusaurous (gram + ve) and the results showed that most of the prepared compounds are sensitive against both types of test organisms in different activities

No full textAttitudes of men and women towards wife beating: Findings from palestinian refugee camps in Jordan
No full textThe aim of this study is to investigate the factors associated with the acceptance of wife beating among currently married men and women living in disadvantaged Palestinian refugee camps in Jordan. The study uses data from a cross-sectional survey of 3,100 households from 12 refugee camps, conducted in 1999, with a sub-sample of 395 married women and men selected for this analysis. Associations between acceptance of wife beating and experience of abuse as well as other risk factors are assessed for men and women separately, using χ 2 tests and odds ratios from binary logistic regression models. The majority of men (60.1percent) and women (61.8percent) believe that wife beating is justified in at least one of the eight hypothetical marital situations presented to them. Among women, those that had been victims of intimate partner violence are significantly more likely to report acceptance of wife beating. Among men, acceptance of wife beating is also significantly associated with their current age, labor force participation, their view on women's autonomy, and their own history as perpetrators of IPV. The majority of respondents justify wife beating in this context, with essentially no difference between men and women. Acceptance of wife beating by both men and women was strongly associated with previous experiences of wife beating adjusting for other risk factors. © 2007 Springer Science+Business Media, LLC.Ahmed S, 2006, AM J PUBLIC HEALTH, V96, P1423, DOI 10.2105-AJPH.2005.066316; Asling-Monemi K, 2003, B WORLD HEALTH ORGAN, V81, P10; Bates LM, 2004, INT FAM PLAN PERSPEC, V30, P190, DOI 10.1363-3019004; Burazeri G, 2005, BRIT MED J, V331, P197, DOI 10.1136-bmj.331.7510.197; Ellsberg MC, 1999, AM J PUBLIC HEALTH, V89, P241, DOI 10.2105-AJPH.89.2.241; Gage AJ, 2005, SOC SCI MED, V61, P343, DOI 10.1016-j.socscimed.2004.11.078; Haj-Yahia MH, 2003, J FAM VIOLENCE, V18, P193, DOI 10.1023-A:1024012229984; Haj-Yahia MM, 2002, PSYCHOL WOMEN QUART, V26, P282, DOI 10.1111-1471-6402.t01-1-00067; Haj-Yahia MM, 2000, FAM PROCESS, V39, P237, DOI 10.1111-j.1545-5300.2000.39207.x; HAMPTON RL, 1994, J COMPARATIVE FAMILY, V28, P105; Hindin MJ, 2003, B WORLD HEALTH ORGAN, V81, P501; HUSSMANNS R, 1992, SURVEYS EC ACTIVE PO; Jewkes R, 2002, SOC SCI MED, V55, P1603, DOI 10.1016-S0277-9536(01)00294-5; Kernic MA, 2003, CHILD ABUSE NEGLECT, V27, P1231, DOI 10.1016-j.chiabu.2002.12.001; Khawaja M, 2004, INT J EPIDEMIOL, V33, P526, DOI 10.1093-ije-dyh039; Khawaja M, 2004, INT J GYNECOL OBSTET, V86, P67, DOI 10.1016-j.ijgo.2004.04.008; Khawaja M, 2005, J EPIDEMIOL COMMUN H, V59, P840, DOI 10.1136-jech.2004.031625; KHAWAJA M, 2001, MARGINS MIGRATION LI; Koenig MA, 2006, AM J PUBLIC HEALTH, V96, P132, DOI 10.2105-AJPH.2004.050872; Koenig MA, 2003, B WORLD HEALTH ORGAN, V81, P153; KRUG EG, 2002, WORLD REP VIOL HLTH; Kyriacou DN, 1999, NEW ENGL J MED, V341, P1892, DOI 10.1056-NEJM199912163412505; Lawoko Stephen, 2006, Violence Vict, V21, P645, DOI 10.1891-vivi.21.5.645; Maziak Wasim, 2003, Health Care Women Int, V24, P313; McFarlane JM, 2003, PEDIATRICS, V112, pE202, DOI 10.1542-peds.112.3.e202; Oyediran Kolawole Azeez, 2005, Afr J Reprod Health, V9, P38; Parish WL, 2004, INT FAM PLAN PERSPEC, V30, P174, DOI 10.1363-3017404; Raj A, 2003, AM J PUBLIC HEALTH, V93, P435, DOI 10.2105-AJPH.93.3.435; Rani Manju, 2004, Afr J Reprod Health, V8, P116, DOI 10.2307-3583398; Saltzman LE, 2000, AM J PREV MED, V19, P325, DOI 10.1016-S0749-3797(00)00241-5; Silverman JG, 2006, AM J OBSTET GYNECOL, V195, P140, DOI 10.1016-j.ajog.2005.12.052; Simon T R, 2001, Violence Vict, V16, P115; Tjaden P, 2000, Violence Vict, V15, P427; Vest JR, 2002, AM J PREV MED, V22, P156, DOI 10.1016-S0749-3797(01)00431-7; Wathen CN, 2003, JAMA-J AM MED ASSOC, V289, P589, DOI 10.1001-jama.289.5.589; WATTS C, 2003, PUTTING WOMEN 1 ETHI19181
Adverse Selection and Private Health Insurance Coverage in India - A Rational Behaviour Model of Insurance Agents under Asymmetric Information
No full textIn the backdrop of the low level of health insurance coverage in India, this study examines the determinants of the scaling-up process of health insurance by analyzing the rational behaviour of an insurance agent facing a trade-off between selling health insurance and other forms of insurance subject to his limited time and efforts, and the implications of such behaviour on adverse selection and equity. The paper presents various pre-conditions affecting the rational behaviour of insurance agents and also discusses two new concepts insurance habit and asymmetric information on health insurance schemes. Further, the study examines various strategies followed by insurance agents for maximizing their net incomes. The theoretical proposition is empirically validated by applying a binary Probit model and the primary data collected by the author is used in this context. The study concludes that given the existing incentive systems in the Indian insurance market for promoting various forms of insurance, the low level of insurance awareness among the general public, coupled with the dominant role of insurance agents in the market results in a situation of : 1. Low level of health insurance coverage, 2. No adverse selection and 3. Inequity in health insurance coverage.Health Insurance, Insurance Agent, Asymmetric Information, Adverse Selection and Insurance Habit
