Field experiments were conducted using Ceranock bait station, ＂attract and kill＂ system to combat Mediterranean fruit fly, Ceratitis capitata, in citrus orchards of Baghdad and Wasit governorates, Iraq, during 2013-2014 season. Control program was implemented in six citrus orchards of mixed citrus varieties： Orange, Citrus sinensis; Mandarin, C. reticulate; Lemon, C. lemon; and Bergamot, C. aurantium. Ceranock traps 240/ha were hanged in trees of two separate orchards in each location, with third orchard served as control. Delta and McPhail traps supplied with pheromone were used to monitor Medfly population density in treated and control orchards. Results indicated that Medfly activity and presence in citrus orchards started during the first week of October coincide with the beginning of fruits ripening. The result indicated that Medfly population density in Wasit orchards was more than that of Baghdad orchards. The total trapped insects after two weeks of Ceranock were 59, 94, 142 and 205, 277, 765 adults for the firsst, second and the control orchards in the two locations, respectively. The percentage of fruit injuries were increased dramatically when fruits mature and its color turn to yellowish reaching of 35%, 56%, 21% and 32% in mandarin and orange fruits in Baghdad and Wasit orchards, respectively, compared with 3%, 4%, 4% and 5% in treated orchards, respectively. Calculated percentage of fruit damage indicated that reduction in injuries were 97% in mandarin and 96% in orange at Baghdad orchards and were 95% and 96%, respectively, in Wasit orchards. The results of this study demonstrate clearly the efficacy of Ceranock bait station, ＂attract and kill＂ system as a control measure for Medfly in citrus orchards.

作者： Ayoub A. Bazzaz Ouhood M. shakir Raghad H. Alabbasy Department of Basic Sciences Faculty of Dentistry University of Kekuk Kerkuk Iraq Department of Applied Science Faculty of Applied Science University of Samarra Samarra Iraq

The prevalence of two gastrointestinal parasites the Entamoeba histolytica and Giardia lamblia parasites and their impact on some blood parameters, i.e. packed cell volume (PCV), hemoglobin (Hb%) and total protein (TP) of a total 780 patients (children and adults) admitted to Samarra General Hospital were assessed. Samples of fresh feces were collected in normal physiological saline and examined using Olympic microscopes. The frequency of the parasite E. histolytica was 12.8% (46.3% male and 53.6% female). The highest frequency of infection of E. histolytica (13.8%) was found at age group (1 - 5 years old) followed by 41 years old). The highest rate of infection (33.9%) was found in September and the lowest (2.2%) in January. Similarly, the general infection frequency of the parasite G. lamblia was 3.9% with the highest rate at ages 1 - 20 years old and the lowest rate was 7.3% for >50 years old. The monthly, highest rate of infection (5.2%) was in August and least (2.2%) in January (2.2%). The frequency of total protein (TPD) in the blood relevant to the presence of parasite E. histolytica and G. lamblia was 4.6% and 1%, respectively. It is concluded that the above two parasites are the most common gastrointestinal parasite in Iraq whose pathogenesis to be which is likely to escalate during the summer seasons and at low hygienic services environment. There has been an irrelevance neither to anemia nor total protein deficiency. It is recommended that Ministry of Health in Iraq should not share the global idea of defining the giardiasis as a neglected disease.

对可用于接触面应力变形及强度特性试验的直剪仪、单剪仪及环剪仪的优缺点进行了比较分析。对某土料与混凝土接触面的应力-变形及强度特性进行了单剪试验研究,试验包括土-混凝土接触面及土-泥皮-混凝土接触面两种。同时,将已有的环剪试验成果与单剪试验结果进行了比较分析。研究了环剪试验与单剪试验成果的差异。结果表明,单剪试验测得的抗剪强度比环剪试验测得的低30%～40%,环剪试验用于接触面强度特性研究较合适,而单剪试验用于较低应力水平下的应力-变形试验更好,泥皮的存在使得接触面强度降低30%左右。

作者： Shaymaa Mahdi Salih Ibtehal K. shakir Abdulkareem M. A. Al-Sammarraie Department of Chemical Engineering College of Engineering University of Baghdad Baghdad Iraq Department of Chemistry College of Science University of Baghdad Baghdad Iraq

The aggressive effect of chloride anion in comparison to iodide anion on the pitting corrosion attack of 304 and 304L stainless steel (SS) alloys was investigated by using the cyclic potentiodynamic polarization test at 0.6 M Sodium Halide salts (NaX) solution and different temperatures. The two alloys 304 and 304L SS suffered from severe pitting corrosion at room temperature up to 50°C in a chloride containing solution with the higher resistance observed for 304L in comparison to the 304 while on pits were detected in iodide solution for both alloys. The pitting potentials of the two alloys in 0.6 M NaCl solution reduced with the increase of the temperature. Examination of the alloys’ surfaces was conducted by using the scanning electron microscopes where it revealed that the occurrence of pitting attack seems like hemispherical or irregular pits with different sizes.

在多种应用背景下,怎样回收系统中少量的热或者废热是最近的研究热点之一,引起了学术界的广泛关注。虽然,有许多科研结果表示可以回收利用浪费掉的能源或热量,但是这些系统并没有完全解决上述问题。怎样设计一种能够适应性强且造价低廉的废热回收系统仍旧是一个值得研究的问题。本研究的主要工作是设计了一种新型朗肯蒸汽循环系统,以解决在极低温度和低压力下朗肯蒸汽循环系统存在的缺陷。改良后的新系统和老式朗肯循环系统一样都是使用水做流体朗肯循环,改良性设计主要是在新系统中使用了吸收剂,它是在特定浓度中可以发挥吸收作用的材料。吸收材料在吸收涡轮机的出口后的膨胀过程中可以吸收水蒸汽,使得在吸收材料中完全溶解的蒸汽(湿气)及混合物一起泵入循环中。其改良的目的是取代朗肯循环中的凝汽器,并在真空压力下降低湿气的压力来解决蒸汽饱和温度这一限制问题,而不会对工作效率产生任何影响。在低温及低压的条件下,老式朗肯循环系统提供这样的效果是几乎不可能的。改良关键点就是根据特定的热力学性质和规格而选定了溴化锂做为吸收材料。在低压蒸汽和相对较低温度的工作条件下,湿气在恒定的压力和温度下进入吸收器(根据操作条件选择溶液浓度)。湿气蒸汽与吸热材料在吸热过程中相互作用,然后通过蒸汽热将水完全溶解到环境中,压力泵将混合物(湿蒸汽和溴化锂)抽送到蒸汽发生器。以这种方式,我们在很宽泛的低压下,而且并不影响吸收剂温度(低压等温)就可以将蒸汽转换成蒸汽和吸收剂的混合溶液。在蒸汽发生器运行时从水和吸收剂混合物中分离释放大量水蒸气。释放的水蒸汽继续工作,从超加热器接收额外的热量,然后驱动到涡轮机进行扩大再生产工作。蒸汽发生器底部的剩余溶液循环到节流阀上的吸收器,被吸收再利用以执行下一个同样的循环过程。本文的研究内容包括:吸收剂的选择和吸收剂特性的研究;选择合金材料及工艺以避免腐蚀;系统建模和系统分析。系统分析老式朗肯循环和改良后新系统之间的比较,两者都使用水为工作流体。这两个系统有相同的工作参数。热力学模拟表明,改良后新的系统比老式朗肯循环系统在同样的的操作条件下工作更有效。以及分析了在工作温度和压力过低的条件下老式朗肯蒸汽循环失败的原因,证明了改良后新系统在低温和低压的条件下更具有节能效果和灵活性。有限时间系统分析法提供了热力学模拟的假设参数的温度数据,这对在估计系统的热效率时,它的理想工作率(卡诺效率)和它在内部工作时的可逆条件提供了真正的比较。

Food and Nutrition Sciences 2017年第7期8卷 733-745页

作者： Samar S. Qasim Khalida A. shakir A. B. Al-Shaibani Marie K. Walsh Department of Food Science College of Agriculture University of Baghdad Baghdad Iraq College of Biotechnology Al-Nahrain University Baghdad Iraq Department of Nutrition Dietetics and Food Sciences Utah State University Logan UT USA

The effects of nutrients and physical conditions on phytase production were investigated with a recently isolated strain of Aspergillus tubingensis SKA under solid state fermentation on wheat bran. The nutrient factors investigated included carbon source, nitrogen source, phosphate source and concentration, metal ions (salts) and the physical parameters investigated included inoculum size, pH, temperature and fermentation duration. Our investigations revealed that optimal productivity of phytase was achieved using wheat bran supplemented with: 1.5% glucose. 0.5% (NH4)2SO4, 0.1% sodium phytate. Additionally, optimal physical conditions were 1 × 105 spore/g substrate, initial pH of 5.0, temperature of fermentation 30°C and fermentation duration of 96 h. Overall, a 34% improvement in phytase activity was achieved by using the optimal conditions.

Ethnopharmacological relevance: Aqarqarha (Anacyclus pyrethrum) DC root has long been used as a traditional an-tiepileptic remedy in Unani system of medicine over centuries. Aim of the Study: To rationalize the ethnomedical claim and screen for anxiolytic and neurotoxicity profile of ethanolic extract of Aqarqarha (Anacyclus pyrethrum) root (APE). Materials and Methods: The anticonvulsant and anxiolytic potential of APE (100-800 mg/kg) was evaluated against Pentylenetetrazole (PTZ), Bicuculline (BCL), Increasing current electroshock (ICES) and Elevated plus maze(EPM) models. Rotarod test was employed as neurotoxicity model including an additional higher dose (1600 mg/kg). Results: The APE showed significant anticonvulsant activity (p i.p.) in a dose-dependent manner but against BCL (30 mg/kg, i.p.) at the dose 800 mg/kg only (p 0.05). The extract also showed anxiolytic behaviour in EPM (p Conclusions: The results suggested significant anticonvulsant activity of APE against PTZ and BCL but failure against ICES. Moreover, APE also exhibited anxiolytic potential without any evidence of neurotoxicity at the effective dose level. We concluded that anticonvulsant effect of APE is probably mediated by enhancing GABAergic neurotransmission.
