Review of design parameters for FRP-RC members detailed according to ACI 440.1R-06

Fares Jnaid,Riyad Aboutaha 사단법인 한국계산역학회 2013 Computers and Concrete, An International Journal Vol.11 No.2

This paper investigates the parameters that control the design of Fiber Reinforced Polymer (FRP) reinforced concrete flexural members proportioned following the ACI 440.1R-06. It investigates the critical parameters that control the flexural design, such as the deflection limits, crack limits, flexural capacity,concrete compressive strength, beam span and cross section, and bar diameter, at various Mean-Ambient Temperatures (MAT). The results of this research suggest that the deflection and cracking requirements are the two most controlling limits for FRP reinforced concrete flexural members.

The present report examined the effects of essential oils (EOs) from Satureja hortensis L. and Salvia fruticosa M. on the viability and outer membrane permeability of the periodontopathogen Fusobacterium nucleatum, a key bacteria in oral biofilms, as well as the inhibition of matrix metalloproteinase (MMP-2 and MMP-9) activities in epithelial cells exposed to such bacteria. Membrane permeability was tested by measuring the N-phenyl-1-naphthylamine uptake and bacterial viability by using the commercially available Live/Dead BacLight kit. In addition, gelatin zymography was performed to analyze the inhibition of F. nucleatum-induced MMP-2 and MMP-9 activities in HaCaT cells. We showed that 5, 10, and 25 μL/mL of Sat. hortensis L. EO decreased the ratio of live/dead bacteria and increased the outer membrane permeability in a range of time from 0 to 5 min. Treatments with 10 and 25 μL/mL of Sal. fruticosa M. also increased the membrane permeability and 5, 10, and 25 μL/mL of both EOs inhibited MMP-2 and MMP-9 activities in keratinocytes induced after exposure of 24 h to F. nucleatum. We conclude that antibacterial and antigelatinolytic activities of Sat. hortensis L. EO have potential for the treatment of periodontal inflammation.

Background/Aims: Perianal fistulas are a debilitating manifestation of Crohn’s disease (CD). Despite the advent of anti-tumor necrosis factor (anti-TNF) therapy, the medical management of fistulizing CD continues to be challenged by unmet needs. We conducted a systematic review and meta-analysis of the effectiveness of vedolizumab for the management of perianal fistulizing CD. Methods: A search of PubMed, EMBASE and the Cochrane Library was performed from inception to June 2020 for studies reporting rates of perianal fistula healing in CD patients treated with vedolizumab. The primary outcome of interest was complete healing of perianal fistulas and the secondary outcome was partial healing. The pooled fistula healing rates with 95% confidence intervals (CI) were calculated utilizing a random effects model. Results: A total of 74 studies were initially identified, 4 of which met the inclusion criteria. A total of 198 patients with active perianal fistulas were included, 87% of whom had failed previous anti-TNF therapy. The pooled complete healing rate was 27.6% (95% CI, 18.9%-37.3%) with moderate heterogeneity (I2=49.4%) and the pooled partial healing rate was 34.9% (95% CI, 23.2%-47.7%) with high heterogeneity (I²=67.1%). Conclusions: In a meta-analysis of 4 studies that included 198 patients with perianal fistulizing CD, the majority of whom had failed previous anti-TNF therapy, vedolizumab treatment led to healing of perianal fistulas in nearly one-third of the patients. The lack of high-quality data and significant study heterogeneity underscores the need for future prospective studies of fistula healing in patients receiving anti-integrin therapy.

Objectives: Fatigue is the most frequently reported symptom experienced by cancer patients and has a profound effect on their quality of life (QOL). The study aimed to determine the impact of fatigue on QOL among breast cancer patients receiving chemotherapy and to identify the risk factors associated with severe fatigue incidence. Methods: This was an observational prospective study carried out at multiple centers. In total, 172 breast cancer patients were included. The Functional Assessment of Chronic Illness Therapy-Fatigue Questionnaire was used to measure QOL, while the Brief Fatigue Inventory (BFI) was used to assess the severity of fatigue. Results: The total average mean and standard deviation of QOL were 84.58±18.07 and 4.65±1.14 for BFI scores, respectively. A significant association between fatigue and QOL was found in linear and multiple regression analyses. The relationships between fatigue severity and cancer stage, chemotherapy dose delay, dose reduction, chemotherapy regimen, and ethnicity were determined using binary logistic regression analysis. Conclusion: The findings of this study are believed to be useful for helping oncologists effectively evaluate, monitor, and treat fatigue related to QOL changes.

Intrusion Detection: Supervised Machine Learning

Fares, Ahmed H.,Sharawy, Mohamed I.,Zayed, Hala H. Korean Institute of Information Scientists and Eng 2011 Journal of Computing Science and Engineering Vol.5 No.4

Due to the expansion of high-speed Internet access, the need for secure and reliable networks has become more critical. The sophistication of network attacks, as well as their severity, has also increased recently. As such, more and more organizations are becoming vulnerable to attack. The aim of this research is to classify network attacks using neural networks (NN), which leads to a higher detection rate and a lower false alarm rate in a shorter time. This paper focuses on two classification types: a single class (normal, or attack), and a multi class (normal, DoS, PRB, R2L, U2R), where the category of attack is also detected by the NN. Extensive analysis is conducted in order to assess the translation of symbolic data, partitioning of the training data and the complexity of the architecture. This paper investigates two engines; the first engine is the back-propagation neural network intrusion detection system (BPNNIDS) and the second engine is the radial basis function neural network intrusion detection system (BPNNIDS). The two engines proposed in this paper are tested against traditional and other machine learning algorithms using a common dataset: the DARPA 98 KDD99 benchmark dataset from International Knowledge Discovery and Data Mining Tools. BPNNIDS shows a superior response compared to the other techniques reported in literature especially in terms of response time, detection rate and false positive rate.

Fares Mujahed,Tarik Atan 숙명여자대학교 아시아여성연구원 2017 Asian Women Vol.33 No.4

This study seeks to examine Palestinian attitudes toward women holding leading administrative positions. A structured questionnaire was used to examine attitudes, and to identify the main impediments to women’s promotion and advancement to leading administrative positions. Employees in the Palestinian public sector institutions operating in the West Bank were surveyed. Results indicate that respondents generally show negative attitudes toward women in top administrative positions. Findings also revealed that cultural attitudes posed significant impediments to women’s advancement to these positions. Other barriers include gender stereotypes and work-family conflicts. Implications for future research and practice are discussed.

Groups having many 2-generated subgroups in a given class

Fares Gherbi,Nadir Trabelsi 대한수학회 2019 대한수학회보 Vol.56 No.2

If $\mathfrak{X}$ is a class of groups, denote by F$\mathfrak{X}$ the class of groups $G$ such that for every $x\in G$, there exists a normal subgroup of finite index $H(x)$ such that $\left\langle x,h\right\rangle \in\mathfrak{X}$ for every $h\in H(x)$. In this paper, we consider the class F$\mathfrak{X}$, when $\mathfrak{X}$ is the class of nilpotent-by-finite, finite-by-nilpotent and periodic-by-nilpotent groups. We will prove that for the above classes $\mathfrak{X}$ we have that a finitely generated hyper-(Abelian-by-finite) group in F$\mathfrak{X}$ belongs to $\mathfrak{X}$. As a consequence of these results, we prove that when the nilpotency class of the subgroups (or quotients) of the subgroups $\left\langle x,h\right\rangle$ are bounded by a given positive integer $k$, then the nilpotency class of the corresponding subgroup (or quotient) of $G$ is bounded by a positive integer $c$ depending only on $k$.

A Practical Guideline of Selecting Stakeholders for Requirements Elicitation – An Empirical Study

Fares Anwar,Rozilawati Razali 보안공학연구지원센터 2015 International Journal of Software Engineering and Vol.9 No.2

Requirements elicitation is widely regarded as the most challenging activity within the scope of requirements engineering. The activity concerns the understanding of problems that a system should address, which later leads to the identification of system requirements. As an abstract process, its effectiveness is greatly influenced by the credibility and suitability of the stakeholders involved. High-quality requirements could only be achieved if they are gathered from the right stakeholders. There are several methods proposed by earlier studies that could guide the selection of stakeholders for requirements elicitation. The methods however are theoretical rather than pragmatic. Therefore, there is a need of practical method that could help practitioners in identifying and selecting the appropriate stakeholders. Prior to having such a method, the contributing factors that influence the selection process should be firstly identified and understood. This study addressed this issue by collating the important factors that contribute to an effective selection of stakeholders for requirement elicitation purposes. The factors were identified through a series of empirical study conducted in two countries: seven in-depth individual interviews and a focus group session with five experienced practitioners. The results were analysed by using content analysis through Nvivo 9. The factors were then merged as a practical guideline that consists of a step-by-step procedure. This guide can be used by practitioners to execute the process of identifying and selecting the appropriate stakeholders for requirements elicitation.

Mohamed Fares Mahjoubi,Anis Ben Dhaou,Mohamed Maatouk,Nada Essid,Bochra Rezgui,Yasser Karoui,Mounir Ben Moussa 한국간담췌외과학회 2023 Annals of hepato-biliary-pancreatic surgery Vol.27 No.4

Backgrounds/Aims: Acute cholecystitis is a rare condition in pregnant women, potentially affecting the maternal and fetal prognosis. Our aim was to report the main clinical and paraclinical features of acute cholecystitis during pregnancy and therapeutic modalities. Methods: We conducted a case series analysis recording pregnant patients with acute cholecystitis admitted to our surgery department over a period of 11 years. We collected clinical data, paraclinical features, and management modalities related to cholecystitis. Results: There were 47 patients. Twenty-eight percent was in the first trimester of pregnancy, 40% in the second, and 32% in the third trimester. Abdominal pain was located in the right hypochondrium in 75% of cases. Fever was noted in 21% of cases. C-reactive protein was elevated in 39% of patients. Cholestasis markers were high in four patients. Abdominal ultrasound showed a distended gallbladder in 39 patients, with thickened wall in 34 patients, and gallbladder lithiasis in all cases. No patient had a dilated main bile duct. All patients received intravenous antibiotic therapy. Tocolysis was indicated in 32 patients. Laparoscopic cholecystectomy was performed in 32 cases (68%), and open cholecystectomy in 15 cases (32%). Postoperative course was uneventful in 42 patients, and complicated in 5 patients. Rate of complications was statistically higher after open cholecystectomy (p = 0.003). Morbidity rate was higher in the third trimester (p = 0.003). Conclusions: Delay in the diagnosis of acute cholecystitis during pregnancy can lead to serious complications. Management is based on antibiotic therapy and cholecystectomy. Laparoscopic cholecystectomy appears to be less morbid than open cholecystectomy.
