作者： Mohammed Alhejaili douglas Olson Kayanush Aryana School of Nutrition and Food Sciences Louisiana State University Agricultural Center Baton Rouge LA USA

Myrrh, commercially availab.e as a b.own powder, is a natural flavoring sub.tance approved for food use b. US Food and Drug Administration and has antib.cterial and antifungal activity against pathogens. Myrrh is commercially availab.e as a b.own powder. The ob.ective was to determine the effect of myrrh on the color (L*, a*, b., C*, h*) and viscosity of yogurt over refrigerated storage. Myrrh dispersion was prepared and incorporated at a 1% v/v level into yogurt. A control with no myrrh was also prepared. Three replications were conducted. At a small usage level of 1% v/v, myrrh influenced the color attrib.tes L*, a* and h* b.t did not influence the viscosity of the plain yogurts.

Advances in Chemical Engineering and Science 2023年第1期13卷 19-35页

作者： Onoh Ikechukwu maxwell Mb.h Gordian Onyeb.chukwu Okeke Elochukwu Chinonso Igwilo Christopher Nnaemeka Eze Kenneth Afamefuna Department of Chemical Engineering Enugu State University of Science and Technology ESUT Enugu Nigeria Department of Science Lab.ratory Technology Federal College of Agriculture P.M.B. Ishiagu Nigeria

The comparative effectiveness of remediating water polluted with crude oil, using environment-friendly b.cteria (Pseudomonas aeruginosa) and fungi (Aspergillus niger) were investigated. The samples were separately treated with Aspergillus niger and Pseudomonas aeruginosa. The b.oremediation kinetic efficiency for these systems was studied. At the end of the b.oremediation periods, the oil and grease content of the samples decreased from 47.0 mg/L in the untreated sample to 7.0 mg/L after 20 days when inoculated with b.cteria while the sample inoculated with fungi decreased to 10.0 mg/L. Post analysis when inoculated with b.cteria showed a fall in the value of the b.ological oxygen demand (b.D) from 73.84 mg/L to 33.28 mg/L after 20 days, while, the fungi inoculated sample showed a reduction from 73.84 mg/L to 38.48 mg/L. The b.odegradation process with the b.cteria was consistent with the pseudo-first-order model with a rate constant of 0.0891 day-1, while the b.odegradation process with the fungi was consistent with the first order reaction model with a rate constant of 0.422 day-1. The degree of degradation after the 20th day of inoculation with Pseudomonas aeruginosa was 85.11%, while with Aspergillus niger was 78.72%. Thus, the results ob.ained showed that, Pseudomonas aeruginosa performed b.tter than Aspergillus niger. The b.oremediation data with fungi fitted the first-order model, while that of the b.cteria fitted the pseudo-first-order model. Therefore, the data ob.ained in this study could b. applied in the design of a b.oremediation system for potential application to remediation of crude oil polluted water.

World Journal of Cardiovascular Diseases 2013年第8期3卷 512-518页

A serological survey conducted among 196 pregnant women resident in and around Maiduguri, an urb.n town in north eastern Nigeria showed that 33 (16.8%) were asymptomatic carriers of hepatitis b.virus surface antigen (Hb.Ag). They are within the age range of 14-40 years with mean (± SD) age of 24.7 (± 6.3). The women attend antenatal clinic at the State Specialist Hospital, a secondary health facility in Maiduguri, b.rno state. The women are all heterosexuals. The distrib.tion of Hb.Ag carrier rate according to age of women studied showed a significant (p = 0.0061) increase of the prevalence of Hb.Ag from 4 (8.7%) in the lower age group (39 years). According to the numb.r of pregnancies, the prevalence of Hb.Ag infection increased significantly from 6 (9.2%) among primiparous to 13 (13.7%) and 14 (38.9%) among multiparous and grand multiparous respectively. The carrier rate of Hb.Ag infection among the pregnant women studied b.sed on their duration of pregnancies and their social class showed no significant differences. However, according to the factors known to b. commonly associated with the highest risk of transmission of Hb. such as history of b.ood transfusion, Trib.l marks/tattooing, use of sharps, sharing of articles, history of jaundice in the women and husb.nds, history of sexually transmitted infections (STIs) of the women and husb.nds and the type of marriage (monogamous or polygamous), numb.r of sexual relationships per week, only the history of b.ood transfusion was significantly associated with Hb.Ag carrier rate (RR = 3.71., 95% Confidence Interval (C.I.), 1.89-7.30, p = 0.0078). The study confirms that pregnant women who attend antenatal clinic in this secondary health facility are at higher risk of b.ing infected with the Hb., which could lead to b.th prenatal and post natal transmission to their newb.rns.

为探讨三峡水库调度运行背景下,库区回水区营养盐和叶绿素a时空变化及其相互关系,于2013年5月~2014年5月在三峡库区北岸最大、也是库区水华频发的支流——澎溪河的回水区高阳平湖进行了定点和高频监测.结果表明水体热分层是高阳平湖水华发生的诱导因素.高阳平湖水体热分层发生于春季(3月初),消亡于夏末(9月中旬),冬季没有分层.2014年春季,随着水体分层的发生和发展,表层叶绿素a在69 d内从14.92μg·L-1骤增至183.73μg·L-1,并暴发水华,之后叶绿素a随着混合层深度增加而下降.水体没有分层时,表、中和底层营养盐浓度相近;水体分层之后,各层磷浓度有了明显差异,表层和底层总磷浓度相差(0.18±0.04)mg·L-1.高水位期(9月至次年4月),高阳平湖硝氮和溶解性磷高于低水位期(5~8月)的含量,分别占总氮、总磷浓度的71.4%~95.4%和42.7%~94.4%,是总氮和总磷的主要组成部分,干流倒灌输入的硝氮和溶解性磷是其主要来源.
