A weighted companion of Ostrowski's inequality using three step weighted kernel

There are numerous works suggesting linking SSM models to information systems (IS) models for information systems development. In these works links between SSM and IS models are established at the conceptual level i.e. they provide ways to utilise SSM models to identify or to derive IS models. However, most of them have not provided a method for representing the links explicitly in the combined model. Consequently, the links become subtle and untraceable, looking at the combined model only at the representation level. This paper proposes an approach based on meta modelling to achieve a uniform and formalised representation of models that combine SSM and IS models. The approach allows one to represent not only SSM and IS modelling concepts but also relationships between the concepts in a meta model using the conceptual modelling language Telos. Telos supports meta models to be flexibly specified and extended to meet specific modelling requirements of a particular project. An exemplary application is presented to demonstrate the operationalisation of the proposed approach and to illustrate the uniform representation of combined models. The example also shows benefits of the formalised representation in terms of computer support for managing and retrieving a combined model's meta data

The Role of Digital Library in Bridging the Language Divide: Comparison Study of Arabic and Other Languages

Developing countries are often said to suffer the disadvantages created by a ‘digital divide’ – the gap between the digitally advantaged and the digitally disadvantaged. Much of the attention given to the digital divide had focussed on the most severely disadvantaged countries (particularly in Africa and parts of Asia). This study was examined the phenomenon in the context of developing Arab countries, with a particular focus on the capacity of digital libraries to bridge the ‘divide’ as it applies to research and scholarly communication. This will entail a case study of University of Jordan.A particular focus of the study will be on assessing the particular challenges and frustrations facing Arabic-speaking researchers in their use of networked information services. That is, while the term digital divide is often used as a means of expressing the technology gap between developed and developing countries, it may well be that a further divide is created because of the domination of the languages and content of the developed world in the networked environment.The research will investigate the potential for digital library services to better serve Arabic-speaking scholars, in particular though the increased access to scholarly publishing in Arabic. It will also explore the policy initiatives and constraints that may impact upon the future development and implementation of digital library services for the benefit of Arabic-speaking scholars. There are no current published studies that deal with the capacity of digital libraries to address the digital divide in the developing Arab World. The findings of this research will provide important recommendations aimed at improving the capacity for digital libraries in Jordan and the wider Arab World to promote Arabic scholarship.

Isolation, characterization, and hydrolytic activities of Geobacillus species from Jordanian hot springs

The present study was conducted to isolate, identify, characterize and to determine the enzymatic activities of the thermophilic Geobacillus species from five Jordanian hot springs. Based on phenotypic characters, eight thermophilic isolates were identified and belonged to the genus Geobacillus. The Geobacillus isolates were abundant in all investigated hot springs. The optimal temperature for growth of the isolates was 60 to 65°C and the optimal pH was 6 to 8. Colonies were light yellow circular to rhizoid. The bacterial cells were Gram positive rods and endospore forming. All isolates produced amylase, caseinase, alkaline and acid phosphatases, esterase (C4), esterase lipase (C8), α-Galactosidase, β-Glucuronidase, β-Glucosidase, and N-Acetyl-β-glucosaminidase. Seven isolates produced leucine and valine arylamidases and five isolates produced naphthol-AS-B1- phsphohydrolase. Lipase (C14) activity from two isolates and α-chymotrypsin activity from three isolates were also detected. The phenotypic characterization of those isolates was confirmed by genotypic method using 16S rDNA sequence analysis. Maximal homology of all eight  isolates to genus Geobacillus was observed. Five of these isolates showed greater than 98% homology with Geobacillus stearothermophilus and one isolate showed 100% homology with Geobacillus thermoglucosidasius. Therefore, 16S rRNA gene sequence analysis can be considered as a valuable genotypic tool for the identification and characterization of thermophilic bacteria at genus level. Moreover, enzymatic products of those isolates could receive considerable attention due to their potential applications in biotechnology.Keywords: Thermophiles, Geobacillus, hydrolytic enzymes, hot spring, 16S rRNA

Thermal injury in tonsils and its relation to postoperative pain—a histopathological and clinical study

Objectives: The aim of this study was to compare thermal injury and depth of necrosis of using different monopolar power settings in partial tonsillectomy and correlate the results with the postoperative pain score. Results: The study included a total of 15 patients with mean of age of 5.7 ± 2.57 years. The mean depth of injury was significantly higher for the 25 W side (0.973 ± 0.613) versus the 15 W side (0.553 ± 0.218) (p = 0.023). The postoperative pain score showed no significant differences between both sides. Conclusion: The histopathologic depth of thermal injury is significantly higher with the 25 W monopolar microdissection in comparison to the 15 W; however, it does not seem to correlate with the postoperative pain level. Apparently, power settings of 25 W can be safely used for pediatric intracapsular tonsillectomies, without added postoperative morbidity despite the deeper tissue injury observed in the tonsil.The authors are grateful to the Histology and Electron Microscopy Service (HEMS) team at the i3S (Institute for Research and Innovation in Health, University of Porto) for providing the necessary equipment and the technical support for the electron microscopic analysis

The Jurisprudence of the Court of Cassation in Jordan: Interpreting Judicial Decisions and Case Law

In this paper, we study the role of case law as a source for legal rules, particularly in cases of ambiguity or deficiency of legislative provisions. The Jordanian Court of Cassations use of discretion to interpret or complete provisions in various cases serves as the focus of this study. Three topics are addressed: deducting blood-money from the compensation amount, nullification of a real estate sale contract after fifteen years and granting compensation for moral damage in cases of contractual liability

Indoor environment propagation review

A survey of indoor propagation characteristics is presented, including different models for path loss, shadowing and fast fading mechanisms, different channel parameters including signal strength, power delay, coherence bandwidth, Doppler spread and angle of arrival. The concepts of MIMO channels are also covered. The study also explores many types of deterministic channel modelling, such as Finite Difference Time Domain, Finite Integration Method, Ray tracing and the Dominant path model. Electromagnetic properties of building materials, including frequency dependence, are also investigated and several models for propagation through buildings are reviewed

Application of smooth particle hydrodynamics method for modelling blood flow with thrombus formation

Thrombosis plays a crucial role in atherosclerosis or in haemostasis when a blood vessel is injured. This article focuses on using a meshless particle-based Lagrangian numerical technique, the smoothed particles hydrodynamic (SPH) method, to study the flow behaviour of blood and to explore the flow parameters that induce formation of a thrombus in a blood vessel. Due to its simplicity and effectiveness, the SPH method is employed here to simulate the process of thrombogenesis and to study the effect of various blood flow parameters. In the present SPH simulation, blood is modelled by two sets of particles that have the characteristics of plasma and of platelet, respectively. To simulate coagulation of platelets which leads to a thrombus, the so-called adhesion and aggregation mechanisms of the platelets during this process are modelled by an inter-particle force model. The transport of platelets in the flowing blood, platelet adhesion and aggregation processes are coupled with viscous blood flow for various low Reynolds number scenarios. The numerical results are compared with the experimental observations and a good agreement is found between the simulated and experimental results

Recurrent right sublingual ranula, concomitant with ipsilateral submandibular salivary gland aplasia

AbstractINTRODUCTIONOral ranula is a retention cyst that arises from the salivary gland with recurrence rate of up to 25% after complete excision of ranula and up to 2% in case of complete excision of ranula and sublingual gland.Major salivary gland aplasia is a rare finding that is usually associated with other developmental anomalies.PRESENTATION OF CASEWe report a 15-year-old female patient presented with recurrent intraoral cystic swelling that was documented to be sublingual ranula. CT scan revealed also the absence of right submandibular salivary gland with persistence of its Whartons duct. This combination has never been reported previously.DISCUSSIONThe combination of recurrent sublingual ranula associated with aplasia of ipsilateral submandibular salivary gland and persistence of Whartons duct has never been reported before in the literature, a finding that may provide the base for future research.CONCLUSIONFurther research may prove similar associations between oral ranula and salivary gland aplasia, which may have clinical implications on diagnostic and management plan decisions

How Can We Identify Hijacked Journals?

By developing research and academic centers, the number of performed research articles has also increased. On the other hand, publishing the results of these articles in scientific journals shall also grow. In the meantime, researchers are trying to publish the findings of their research in journals which have been approved by one or more International indices so that such findings can be seen. In order to enhance the academic standards of Universities, proper journal choice will be of interest to researchers, especially those that are indexed in websites such as Thomson Reuters. However, certain forgery frauds researchers by launching fake Web sites that have been named by academic journal titles. In this paper, we introduce an approach to identify this type of journals that will be applicable by researchers in various academic disciplines
