Pure and Fe citrate doped poly (vinyl Alcohol) PVA films with different concentrations (1, 1.0, 0.0, and 2) wt% were prepared by using casting technique. Optical absorption measurements in the wavelength range 211-011 nm were studied and confirmed that PVA films have an direct band gap that decreased from 0..5 to ..54eV as the doping concentration increases to 2wt%. Optical constants such as absorption coefficient, refractive index, Extinction coefficient real and imaginary parts of dielectric constant have been studied; results show that the optical constants of the pure PVA films were increased after doping and with increasing impurity concentration. Urbach energy and optical conductivity were increases with the increasing of impurity concentration. The increase in the density of localized states Eu from 1445 to 1494eV causes an expanding in the Urbach tail and consequently decreases the energy gap.

Numerous studies have been carried out on studying the effect of glass fiber and ZrO2 Nano-particles alone on the mechanical properties of PMMA, to date, no investigations were made that have studied the mechanical properties of PMMA reinforced with glass fiber and zirconium oxide together as a hybrid composite.In this research the effect of addition of glass fibers (woven and chopped) and Zirconium oxide Nano-particles (ZrO2) with different weight percent to the conventional poly (methyl methacrylate) (PMMA) has been evaluated.The conventional acrylic resin was used as 2:1 powder to liquid ratio to prepare pure sample, laminate composite prepared by using woven glass fiber (8wt%, 12wt%), fiber-reinforced composite fabricated by chopped glass fiber (8wt%, 12wt%), particle-reinforced composite prepared by using ZrO2 Nano-powder (1, 2, 3) wt%, and the hybrid composite fabricated by using glass fiber as woven or chopped of the two form with ZrO2 Nano-particles. The flexural strength (F.S.) was measured by using three point-bending test. The mechanical test done in order to compare the flexural strength between pure and composite samples. The form of glass fiber with the same weight percent affects the mechanical properties values. Reinforcing PMMA with woven glass fiber and zirconium oxide increase flexural strength, while incorporation of chopped glass fiber decrease the flexural strength. Using the two materials together as a hybrid composite recorded very high raises of flexural strength values. From the results, it's possible to syntheses a denture base resin with good aesthetic and high mechanical properties from fiber and ZrO2 Nano-particles.
关于玻璃纤维和ZrO2纳米颗粒单独对PMMA力学性能的影响已经进行了大量的研究,但迄今为止,还没有研究玻璃纤维和氧化锆复合增强PMMA的力学性能。研究了在常规聚甲基丙烯酸甲酯(PMMA)中添加不同重量百分比的玻璃纤维(机织纤维和短切纤维)和氧化锆纳米颗粒(ZrO2)的效果。以常规丙烯酸树脂为粉液比2:1制备纯样品、机织玻璃纤维(8wt%、12wt%)制备层状复合材料、短切玻璃纤维(8wt%、12wt%)制备纤维增强复合材料、ZrO2纳米粉(1,2,3)wt%)制备颗粒增强复合材料以及以ZrO2纳米颗粒为机织或短切两种形式的玻璃纤维制备混杂复合材料。采用三点弯曲试验测定了材料的抗弯强度。为了比较纯试样和复合试样的抗弯强度而进行的力学试验。相同重量百分比的玻璃纤维形态影响其力学性能值。添加机织玻璃纤维和氧化锆增强PMMA的抗折强度提高,添加短切玻璃纤维增强PMMA的抗折强度降低。使用这两种材料一起作为混合复合材料记录了非常高的抗弯强度值的提高。由此可见,以纤维和ZrO2纳米颗粒为原料合成具有良好美观性和高机械性能的义齿基托树脂是可能的。

Offline vs. Online Digital Forensics of Cloud-based Services 基于云服务的离线与在线数字取证
Pub Date : 2017-12-01 DOI: 10.22401/JNUS.20.4.18
N. Hassan, Haider M. Jaber
Digital forensics has become important due to the daily use of digital devices in our life, which may lead to evidence that can be useful to law enforcement in legal cases. When using cloud services, a lot of artifacts that might be useful for investigations are stored in the cloud which means that the extraction must be from cloud computers systems. So, the legacy forensics tools may not be usable or less effective due to the geographically distribution of data and legal issues among other issues. The challenges of the cloud digital forensics are discussed in this paper. Also, this paper shows the types of extracting data from cloud services that are offline and online extraction. The offline extraction is concerned with extracting data from a local device that used to access cloud services. While online data extraction is concerned with remote extraction of data from cloud services. A comparison between such two types are demonstrated from many ways according to the result of recent papers to show the situations that each type is useful in.
由于数字设备在我们生活中的日常使用,数字取证变得越来越重要,这可能会导致在法律案件中对执法有用的证据。在使用云服务时,许多可能对调查有用的工件存储在云中,这意味着提取必须来自云计算机系统。因此,由于数据的地理分布和其他问题中的法律问题,遗留的取证工具可能无法使用或效率较低。本文讨论了云数字取证面临的挑战。此外,本文还介绍了从云服务中提取数据的类型,即离线提取和在线提取。离线提取涉及从用于访问云服务的本地设备提取数据。而在线数据提取则涉及从云服务中远程提取数据。根据最近论文的结果,从许多方面论证了这两种类型之间的比较,以显示每种类型的有用情况。

A study was conducted to determine the prevalence of parasites in soil texture (loam) by using four techniques (salt floatation, zinc sulphate floatation, sedimentation and filter paper technique). During the period from December 2012 to May 2013, 70 soil samples were collected and analyzed from six various sites of Baghdad City such as (house garden, vicinity of house, vicinity of gutter, waste dumps, vegetable farm and hospital garden like Alyarmouk teaching hospital and Central teaching hospital of pediatric). The prevalence of soil parasites was as follows: Toxocara spp. eggs isolated by two floatation techniques (salt and zinc floatation techniques), but this parasite appeared significant in its floatation by salt floatation technique (p= 0.042), while protozoan cysts appeared highly significant in zinc floatation technique (p= 0.00001). In addition, larvae of Strongloides stercoralis showed highly significance in sedimentation and filter paper technique (p=0.0001 and p= 0.001) respectively. Furtherly, female of Strongloides stercoralis appeared significant in its isolation in sedimentation (p= 0.0463), Ascaris lumbricoides (ova) showed highly significant in sedimentation technique (p= 0.0043). These results concluded that the Toxocara spp. eggs more prevelant than other parasites in soil samples, and the soil may play an important role in transmission of zoonotic parasite diseases to human. In addition, the control of high population of animals such as stray dogs and cats is necessary to reduce the distribution of parasites.
采用盐浮法、硫酸锌浮法、沉淀法和滤纸法4种技术对土壤(壤土)中寄生虫的流行情况进行了调查。在2012年12月至2013年5月期间,从巴格达市的6个不同地点(房屋花园、房屋附近、排水沟附近、垃圾场、蔬菜农场和医院花园,如alyar穆克教学医院和儿科中心教学医院)收集并分析了70个土壤样本。土壤寄生虫的流行情况如下:两种漂浮技术(盐浮和锌浮)分离出弓形虫卵,但盐浮技术中弓形虫卵的漂浮显著(p= 0.042),锌浮技术中原生虫囊的漂浮显著(p= 0.00001)。此外,粪圆线虫幼虫在沉淀法和滤纸法中分别表现出极显著性(p=0.0001和p= 0.001)。此外,粪强线虫(Strongloides stercoralis)的雌性在沉降技术中表现出显著性(p= 0.0463),蛔虫(lumbricoides)(卵)在沉降技术中表现出极显著性(p= 0.0043)。这些结果表明,土壤样品中弓形虫卵比其他寄生虫更普遍,土壤可能在人畜共患寄生虫疾病向人类传播中起重要作用。此外,有必要控制流浪狗和流浪猫等大量动物,以减少寄生虫的分布。
