Flexural behavior of reinforced concrete beams strengthened with externally bonded Aluminum Alloy plates
Citation: Hayder A. Rasheed, Jamal Abdalla, Rami Hawileh, Adil K. Al-Tamimi, Flexural behavior of reinforced concrete beams strengthened with externally bonded Aluminum Alloy plates, Engineering Structures, Volume 147, 15 September 2017, Pages 473-485, ISSN 0141-0296, https://doi.org/10.1016/j.engstruct.2017.05.067.The objective of this experimental investigation is to study the viability and effectiveness of using Aluminum Alloy (AA) plates as externally bonded flexural reinforcement for reinforced concrete (RC) beams. Ten RC beams were prepared and nine of them were strengthened with externally bonded 2 mm and 3 mm thick AA plates with different mechanical properties. Four strengthened beams had no end wraps or anchorages. Single-layer and double-layer U-wrap CFRP sheets were used in the transverse direction as end anchorages for four strengthened beams and one beam had three double anchorages (two at the ends and one at mid-span). The beams were tested under monotonic load until failure. The goal is to study the effect of using AA plates as externally bonded flexural strengthening material and to explore the effect of end anchorages on the flexural strength and ductility of these beams. The increase in strength over the control unstrengthened specimen ranged from 13% to 40% while the ductility significantly surpassed that of beams strengthened with CFRP sheets. It is observed that the use of end anchorages enhanced the ductility but not the strength of the tested beams. It is also observed that beams without end anchorage failed predominantly in flexure with full de-bonding while beams with end anchorage failed by localized de-bonding and flexure. Furthermore, the performance of the tested beams was compared with numerical predictions by a computer program developed in this study. The results of the numerical models were in close agreement with the measured experimental data. It was concluded that AA plates could be used as an external strengthening material to enhance both the strength and ductility of RC beams in flexure

Impact of 18F-FDG PET/CT, CT and EBUS/TBNA on preoperative mediastinal nodal staging of NSCLC.
Background: Staging of non-small-cell lung cancer (NSCLC) is a multidisciplinary process involving imaging, endoscopic and surgical techniques. This study aims at investigating the diagnostic accuracy of 18F-FDG PET/CT, CT scan, and endobronchial ultrasound/transbronchial needle aspirate (EBUS/TBNA) in preoperative mediastinal lymph nodes (MLNs) staging of NSCLC.
Methods: We identified all patients who were diagnosed with NSCLC at the King Hussein Cancer Center in Amman, Jordan, between July 2011 and December 2017. We collected their relevant clinical, radiological, and histopathological findings. The per-patient analysis was performed on all patients (N = 101) and then on those with histopathological confirmation (N = 57), followed by a per-lymph-node-station basis overall, and then according to distinct N-stage categories.
Results: 18F-FDG PET/CT, in comparison to CT, had a better sensitivity (90.5% vs. 75%, p = 0.04) overall and in patients with histopathological confirmation (83.3% vs. 54.6%), and better specificity (60.5% vs. 43.6%, p = 0.01) overall and in patients with histopathological confirmation in MLN staging (60.6% vs. 38.2%). Negative predictive value of mediastinoscopy, EBUS/TBNA, and 18F-FDG PET/CT were (87.1%), (90.91%), and (83.33%) respectively. The overall accuracy was highest for mediastinoscopy (88.6%) and EBUS/TBNA (88.2%), followed by 18F-FDG PET/CT (70.2%). Dividing patients into N1 disease vs. those with N2/N3 disease yielded similar findings. Comparison between 18F-FDG PET/CT and EBUS/TBNA in patients with histopathological confirmation shows 28 correlated true positive and true negative findings with final N-staging. In four patients, 18F-FDG PET/CT detected metastatic MLNs that would have otherwise remained undiscovered by EBUS/TBNA alone. Lymph nodes with a maximal standardized uptake value (SUVmax) more than 3 were significantly more likely to be true-positive.
Conclusion: Multimodality staging of the MLNs in NSCLC is essential to provide accurate staging and the appropriate treatment. 18F-FDG PET/CT has better overall diagnostic utility when compared to the CT scan. The NPV of 18F-FDG PET/CT in MLNs is reliable and comparable to the NPV of EBUS/TBNA. SUVmax of MLNs can help in predicting metastases, but nevertheless, a positive 18F-FDG PET/CT MLNs particularly if such a result would change the treatment plan, should be verified histopathologically
ETIČKA TEORIJA AL-GAZALIJA
U predmetnom članku autor se bavi pitanjem filozofije morala i njenog značaja unutar filozofsko-teološkog mišljenja Abu Hamida Al-Gazalija (1058-1111). Al-Gazali spada u red najznačajnijih klasika muslimanske intelektualne tradicije, ostavivši iza sebe bogat spisateljski opus. Autor otkriva kako etika ima odlučujuću ulogu kod Al-Gazalija, čija se misao nadaje kao svojevrsna sinteza filozofsko-teološkog, a u potonjem periodu i mistično orijentiranog mišljenja. Kroz svoja dela, kao što su "Ihya Ulum al-Din", "Tahafut al-Falasifa" i "Al-Munqidh min al-Dalal", Al-Gazali integrira sufizam sa šerijatskim učenjem, kritikuje peripatetičku filozofiju i opisuje svoj duhovni put. Al-Gazalijeva interpretacija problema morala imat će ogroman utjecaj na razvoj kasnije filozofsko-teološke misli u islamu, postavljajući temelje za harmonizaciju sufizma s ortodoksnim islamom i uticajući na muslimanske i evropske intelektualne tokove
Double U-slots patch antenna for tri-band wireless systems
File shown is the pre-print version of the published paper, with the title "Connected u-slots pathch antenna for WiMAX applications"ABSTRACT: A compact microstrip patch antenna with two U-slots shape is presented.
Detailed simulation and experimental investigation are conducted to understand the behavior
of the two U-slots. The proposed antenna generates three resonant frequencies at 2.7, 3.3, and
5.3 GHz. It can, therefore, be used in Worldwide Interoperability for Microwave Access compliant
communication equipment. The proposed antenna has two U-slot shaped and two
bridge elements to connect both shapes together to adapt the structure to the desired interest
operating frequency. A comprehensive parametric study has been applied to understand the
effect of each U-slot on the antenna’s performance. Moreover, the current distribution for the
three bands is investigated to give further understanding of the antenna behavior. The proposed
antenna is verified experimentally and the simulated and measured results are in good
agreement
