Recently, the widespread use of devices in the field of electronics has caused people to worry about safety. Using traditional cryptographic algorithms to build a complete cryptographic environment for embedded applications or the Internet of Things (IoT) will not be possible due to space, power, and speed limitations. The focus is on lightweight encryption to overcome these problems. In this paper, we have developed the (PRESENT) algorithm, which is among the lightweight algorithms that are used in the IOT and that keeps pace with the requirements of communication speed at the present time. We also used a physical part with the developed algorithm (an external unit that is a USB and using it as a fingerprint for the system) to generate the key while ensuring that the system does not work until after the external unit is connected to the calculator to provide more security for the system from breaches. The developed algorithm achieved a high speed of execution faster than the original algorithm and passed standard tests for various files (text, image, audio, video). In addition to increasing the degree of complexity than the original algorithm.
最近,电子设备在电子领域的广泛使用引起了人们对安全的担忧。由于空间、功率和速度的限制,使用传统的加密算法为嵌入式应用程序或物联网(IoT)构建完整的加密环境是不可能的。重点是轻量级加密,以克服这些问题。在本文中,我们开发了(PRESENT)算法,它是物联网中使用的轻量级算法之一,符合当前对通信速度的要求。我们还使用了一个具有开发算法的物理部分(一个外部单元,它是一个USB,并将其用作系统的指纹)来生成密钥,同时确保系统在外部单元连接到计算器之后才工作,从而为系统提供更大的安全性。所开发的算法实现了比原算法更快的高执行速度,并通过了各种文件(文本、图像、音频、视频)的标准测试。除了比原算法增加了复杂度之外。

Thirty-one A. baumannii isolates were obtained from Shar and Burn hospitals in Sulaimani City, KRG-Iraq. Bacterial identification was confirmed by detecting both 16S rRNA and blaOXA-51 genes. The detection of carbapenem resistant isolates was carried out using Kirby- Bauer, RAPDEC Carba NP and combined disc assays. A high rate of drug resistance was observed, as 74.2% of the isolates were multidrug-resistant (MDR) and 38.7% were extensively drug-resistant (XDR), while carbapenem-resistant A. baumannii (CRAB) comprised approximately 58% of the isolates. Among CRAB isolates, carbapenemase production was detected by using the RAPDEC Carba NP and the combined disc assays in 88.8% (16/18) and 55.5% (10/18) of the isolates respectively. Phenotypic activity of efflux pump was detected among 22.5% of all isolates and 38.8% of CRAB isolates.  PCR successfully identified the adeA, adeB, adeC, adeR, and adeS genes in 83.9%, 90.3%, 58%, 80.6%, and 90.3% of the isolates, respectively. Eight mutations in adeR and 15 mutations in adeS regulatory genes were recorded. We conclude that carbapenem resistance mechanisms in A. bumanni isolates included mutations in adeRS regulatory genes and production of carbapenemase.

Study of optical, structural and electrical properties of copper oxide films prepared by chemical bath deposition with laser at different concentrations 不同浓度激光化学浴沉积氧化铜薄膜的光学、结构和电学性能研究
Pub Date : 2023-04-27 DOI: 10.25130/tjps.v28i2.1339

In this study, a copper oxide (CuO) thin film was prepared by the (Continuous-Wave) CW laser assisted-chemical bath deposition (LACBD) technique. The effect of laser wavelength on the structural, optical, and electrical properties of CuO film was investigated. The X-ray diffraction (XRD) study shows that the deposited CuO films are crystalline with a monoclinic structure. The optical energy gap increases with the use of a laser during film preparation and it varies from 2.3 to 1.8 eV. The scanning electron microscope (SEM) images confirm that the morphology of the film was dependent on the laser wavelength. Increasing the laser wavelength results in decreasing the grain size of the film which enhancing the crystallization. Energy dispersive X-ray (EDX) analysis confirms the presence of copper and oxygen elements.  Hall measurement revealed that the deposited films are p-type and the electrical conductivity and mobility increased with the use of a laser. The current-voltage characteristics of the p-CuO/p-Si heterojunction were studied in the dark and under illumination. The maximum optical current of the prepared photodetector at a laser wavelength of 550 nm was found to be in the order of 1.59 × 1012 cm.Hz1/2.W-1. The spectral responsivity revealed that the photodetectors exhibit two peaks of response at 450 nm and 800 nm. The maximum responsivity reached was 0.48 A/W at 450 nm and 0.53 A/W at 800 nm for a photodetector prepared at the laser wavelength of 550 nm.
本研究采用连续波激光辅助化学浴沉积(LACBD)技术制备了氧化铜(CuO)薄膜。研究了激光波长对CuO薄膜结构、光学和电学性能的影响。x射线衍射(XRD)研究表明,沉积的CuO薄膜呈单斜晶状。在薄膜制备过程中,随着激光的使用,光能隙增大,在2.3 ~ 1.8 eV之间变化。扫描电镜(SEM)图像证实了薄膜的形貌与激光波长有关。增加激光波长可减小薄膜的晶粒尺寸,从而增强薄膜的结晶性。能量色散x射线(EDX)分析证实了铜和氧元素的存在。霍尔测量结果表明,沉积膜为p型,且电导率和迁移率随激光的使用而增加。研究了p-CuO/p-Si异质结在黑暗和光照条件下的电流-电压特性。所制备的光电探测器在550 nm激光波长处的最大光电流为1.59 × 1012 cm.Hz1/2.W-1。光谱响应率表明,光电探测器在450 nm和800 nm处有两个响应峰。波长为550 nm的光电探测器在450 nm和800 nm处的最大响应度分别为0.48 A/W和0.53 A/W。

Energy dispersive X-ray (EDX) analysis confirms the presence of copper and oxygen elements.  Hall measurement revealed that the deposited films are p-type and the electrical conductivity and mobility increased with the use of a laser. The current-voltage characteristics of the p-CuO/p-Si heterojunction were studied in the dark and under illumination. The maximum optical current of the prepared photodetector at a laser wavelength of 550 nm was found to be in the order of 1.59 × 1012 cm.Hz1/2.W-1. The spectral responsivity revealed that the photodetectors exhibit two peaks of response at 450 nm and 800 nm. The maximum responsivity reached was 0.48 A/W at 450 nm and 0.53 A/W at 800 nm for a photodetector prepared at the laser wavelength of 550 nm.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86296664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
