WEB-BASED DUPLICATE RECORDS DETECTION WITH ARABIC LANGUAGE ENHANCEMENT
Sharing data between organizations has growing importance in many data mining projects. Data from various heterogeneous sources often has to be linked and aggregated in order to improve data quality. The importance of data accuracy and quality has increased with the explosion of data size. The first step to ensure the data accuracy is to make sure that each real world object is represented once and only once in a certain dataset which called Duplicate Record Detection (DRD). These data inaccuracy problems exist due to due to several factors including spelling, typographical and pronunciation variation, dialects and special vowel and consonant distinction and other linguistic characteristics especially with non-Latin languages like Arabic. In this paper, an English/Arabic enabled web-based framework is designed and implemented which considers the user interaction to add new rules, enrich the dictionary and evaluate results is an important step to improve system’s behavior. The proposed framework allows the processing on both single language dataset and bi-lingual dataset. The proposed framework is implemented and verified empirically in several case studies. The comparison results showed that the proposed system has substantial improvements compared to known tools
Different methods of bacterial inoculation on the yield of chamomile blossoms and essential oil
Chamomile is one of the most wide spread medicinal plant cultivated in Egypt. This work aimed at enhancement of blossoms and oil production of chamomile plants via biofertilization with PGPRs under organic farming system. In this study, 6 bacterial strains were applied using two different inoculation techniques. The first application method was throughout soaking the roots of seedlings in the bacterial suspension before transplanting. The second technique was by adding the bacterial inocula to soil 2 weeks after transplantation. The results showed that root dipping method displayed high impact on the yield of chamomile blossoms and essential oil percentage. Furthermore, the soil application of the bacterial inocula didn’t show any significant impact in this respect. Where Paenibacillus polymyxa, Bacillus subtilis, Serratia plymuthica and Streptomyces subrutilus increased the dry weight of chamomile blossoms compared to the control, essential oil content increased significantly in case of Serratia plymuthica, Stenotrophomonas rhizophyla and Bacillus subtilis. The current results also indicated that bacterial strains produced the highest indole-3-acetic acid and gibberellic acid resulted in the highest yield of both flowers and essential oil
Factors associated with cognitive impairment and cognitive concerns in patients with metastatic non-small cell lung cancer
BACKGROUND: Knowledge regarding cognitive problems in metastatic non-small cell lung cancer (mNSCLC) is limited. Such problems may include both patient-reported cognitive concerns and demonstrable cognitive impairment. Greater understanding of these outcomes is needed to inform rehabilitation strategies for these difficulties. We aimed to identify the frequency of cognitive problems and associated factors in patients with mNSCLC. METHODS: In this cross-sectional study, adults with mNSCLC completed validated neuropsychological tests and self-report questionnaires measuring cognitive concerns, neurobehavioral concerns, depression, demoralization, illness intrusiveness, self-esteem, and physical symptoms. Cognitive impairment (performance based) was defined according to International Cancer and Cognition Task Force criteria. Clinically significant cognitive concerns were defined by a score ≥1.5 SD below the normative mean on the Functional Assessment of Cancer Therapy-Cognitive Function Perceived Cognitive Impairment (FACT-Cog PCI). Univariate and multivariate logistic regression analyses were performed to identify associated factors. RESULTS: Of 238 patients approached, 77 participated (median age: 62 years; range: 37-82). Brain metastases were present in 41 patients (53%), and 23 (29%) received cranial irradiation. Cognitive impairment and cognitive concerns were present in 31 (40%) and 20 patients (26%), respectively. Cognitive impairment and cognitive concerns co-occurred in 10 patients (13%), but their severity was unrelated. Cognitive impairment was associated with cranial irradiation (odds ratio [OR] = 2.89; P = .04), whereas cognitive concerns were associated with greater illness intrusiveness (OR = 1.04; P = .03) and lower self-esteem (OR = 0.86; P = .03). CONCLUSIONS: Cognitive impairment and cognitive concerns are both common in patients with mNSCLC but are not necessarily related, and their risk factors differ. The association of illness intrusiveness and self-esteem with cognitive concerns can inform therapeutic interventions in this population
Elastic properties of TeO2-B2O3-Ag2O glasses.
A series of glasses [(TeO2) x (B2O3)1−x ]1−y [Ag2O] y with x = 70 and y = 10, 15, 20, 25 and 30 mol% were synthesised by rapid quenching. Longitudinal and shear ultrasonic velocity were measured at room temperature and at 5 MHz frequency. Elastic properties, Poisson's ratio, microhardness, softening temperature and Debye temperature have been calculated from the measured density and ultrasonic velocity at room temperature. The experimental results indicate that the elastic constants depend upon the composition of the glasses and the role of the Ag2O inside the glass network is discussed. Estimated parameters based on Makishima–Mackenzie theory and bond compression model were calculated in order to analyse the experimental elastic moduli. Comparison between the experimental elastic moduli data obtained in the study and the calculated theoretically by the mentioned above models has been discussed
Removal of Tannic Acid From Aqueous Solution by Cloud Point Extraction and Investigation of Surfactant Regeneration by Microemulsion Extraction
The aim of this work is the extraction of tannic acid (TA) with two commercial nonionic surfactants, separately: Lutensol ON 30 and Triton X-114 (TX-114).The experimental cloud point extraction results are expressed by four responses to surfactant concentration and temperature variations: extent of TA extraction (E), remaining solute (X s,w) and surfactant (X t,w) concentrations in dilute phase and volume fraction of coacervate (Φc) at equilibrium. An empirical smoothing method was used and the results are represented on three dimensional plots. In optimal conditions, the extraction extent of TA reaches 95 and 87 % using TX-114 and Lutensol ON 30, respectively. Sodium sulfate, cetyltrimethylammonium bromide (CTAB) addition and pH effect are also studied. Finally, the possibility of recycling of the surfactant is proved

Influence of isolated backward-facing steps on boundary layers.
The drag of backward-facing steps was experimentally measured in a series of turbulent boundary layer flows and in a laminar flow. The main objective of the investigation was to study the influence of the freestream pressure gradients on the drag values for backward-facing steps in turbulent boundary layer flows. The measured boundary layer characteristics of all the established flows are in very good agreement with other published results and their two-dimensionality was ascertained. Two different techniques have been used to measure the drag of such steps. The momentum thickness technique was not suitable for determining the drag of such small irregularities, since the incremental increase in the momentum thickness due to the irregularities was small and the method of calculation was crude. The pressure distribution technique was found to be a more suitable method of estimating this drag. When applied appropriately the measurement uncertainty was small. The drag results published by Gaudet and Johnson for backward-facing steps in a zero-pressure gradient have been considerably extended for a number of turbulent boundary layer flows with values of pressure gradient parameter, a, from -0.97 X 10-3 to 9.14 X 10-3. For small steps results covered a range of irregularity Reynolds number of 150 to 900. For large steps in zero-pressure gradient flow this range was increased up to 3500, and up to 2000 in a mild adverse pressure gradient flow. The drags of backward-facing steps in a laminar boundary layer flow on a flat plate have been measured by the pressure distribution technique. No correlation was made for the drag of such steps in the laminar boundary layer, however a comparison between the total drag of the plate with and without the largest step showed that the total drag of the plate increased by only some 65 % of the clean surface drag value
Determination of Number of Infected Cells and Concentration of Viral Particles in Plasma during HIV-1 Infections Using Shehu Transformation
In this paper, the authors determine the number of infected cells and concentration of infected (viral) particles in plasma during HIV-1 (human immunodeficiency virus type one) infections using Shehu transformation. For this, the authors first defined some useful properties of Shehu transformation with proof and then applied Shehu transformation on the mathematical representation of the HIV-1 infection model. The mathematical model of HIV-1 infections contains a system of two simultaneous ordinary linear differential equations with initial conditions. Results depict that Shehu transformation is very effective integral transformation for determining the number of infected cells and concentration of viral particles in plasma during HIV-1 infections
