Numerical Study of 3-D Liquid Sloshing in an Elastic Tank by MPS-FEM Coupled Method

The sloshing phenomenon in a partially loaded oil tanker or liquid natural gas ship is a typical fluid-structure interaction problem involving multi-physics, violent free-surface flow, and nonlinear structural response. In the past decades, the complex phenomenon has been commonly investigated without consideration of the hydro-elastic behaviors of the bulkheads. In our previous work, the liquid sloshing phenomenon in a two-dimensional (2-D) elastic tank was numerically studied. However, the bulkheads of the tank will deform within the three-dimensional (3-D) space in reality. So, it is necessary to study the 3-D sloshing problem in an elastic tank. In this article, a hybrid approach is developed within the Lagrangian system. The moving particle semiimplicit (MPS) method is used to simulate the evolution of 3-D flow with a violent free surface, and the finite element method (FEM) is used for the numerical analysis of structural response due to the impact loads of the sloshing flow. To couple the MPS method and the FEM method, an interpolation scheme based on the kernel function of the particle method is proposed for the communication on the isomerous interface between the fluid and structure domains. The reliability of force and deformation interpolation modules is validated by two tests. Then, the sloshing phenomenon in a 3-D elastic tank is numerically investigated and compared against the previous published 2-D results. By varying the Young's modulus of the tank walls, characteristics regarding the evolutions of free surface, variation of impact pressures, and dynamic responses of the structures are presented. To support the transportation demands of natural resources, more and more vessels, such as the very large crude carriers and the liquid natural gas carriers, are manufactured. For these huge structures, risks such as local deformation or even damage of cargo-containment systems resulting from sloshing phenomena subsequently increase. Therefore, it is necessary to take the elasticity of the tank walls into account in the research of sloshing phenomena (Dias & Ghidaglia 2018). However, the phenomena involving the vibrations of the tank walls are complex. In the process of sloshing wave interacting with elastic bulkheads, the fragmentation, splash, and fusion of water are observed. Meanwhile, the structures vibrate nonlinearly under the impact loads resulting from the sloshing wave. These phenomena are hard to simulate realistically by the traditional mesh-based methods.
Reliability and Validity of the Persian Version of the Professional Self Identity Questionnaire (PSIQ)

Background: Professional identity is a vital component of medical education that affects the future practice of medical students. There is a notice of the lack of a reliable and valid Persian scale to measure the students' readiness for professional identity.Objective: This present study aims to determine whether or not the PSIQ can be adapted for Persian healthcare professions.Methods: A cross-sectional study was performed among medical students (years of 4-7) in Shiraz medical school. A total of 175 students completed the Persian version of PSIQ using convenience sampling. Categorical confirmatory factor analysis (CCFA) and Cronbach's alpha coefficient were used to investigate the questionnaire's validity and reliability. Moreover, R.3. 6.2 software, by using the lavaan and semPlot packages in it, was used for data analysis and the path diagram.Results: The indices of the goodness of fit of the model were used for the professional self-identity, which including root mean square error of approximation (RMSEA), Tuker-Lewise index (TLI), and comparative fit index (CFI) ( RMSEA=0.055, CFI=0.996, and TLI=0.994). The Cronbach's alpha coefficients for these three factors of "profession-specific tasks," "generic attributes," and "inter-personal tasks" subscales were 0.762, 0.622, and 0.747, respectively (p-value<0.05). The internal consistency of the whole questionnaire measured by Cronbach's alpha was 0.873. The set of these fit statistics show that the hypothesized three-factor model fits the sample data. Therefore, all nine items were significantly loaded on the three domains (Profession specific tasks, Generic attributes, Interpersonal tasks). Conclusion: The Persian translated version of the PSIQ may be an appropriate, valid and reliable tool for assessing medical students' health professional self-identity attitudes in Iran.
DEPARTEMENT TOEGEPASTE ECONOMISCHE WETENSCHAPPEN

A copycat strategy uses visual similarity to an established leader as a persuasion tool. Although not uncommon in the marketplace, little is known about consumer response to such imitation. Contrary to speculation regarding consumer sensitivity to salient persuasion tactics, we find only conditional evidence that consumers spontaneously penalize brands that blatantly imitate market leaders. The results are discussed in the context of common marketing wisdom regarding the virtues of differentiation.
Departement Toegepaste Economische Wetenschappen an Exact Procedure for the Resource-constrained Weighted Earliness-tardiness Project Scheduling Problem an Exact Procedure for the Resource- Constrained Weighted Earliness-tardiness Project Scheduling Problem an Exact Procedure for the Resource-constr

In this paper we study the resource-constrained project scheduling problem with weighted earliness-tardiness penalty costs. Project activities are assumed to have a known deterministic due date, a unit earliness as well as a unit tardiness penalty cost and constant renewable resource requirements. The objective is to schedule the activities in order to minimize the total weighted earliness-tardiness penalty cost of the project subject to the finish-start precedence constraints and the constant renewable resource availability constraints. With these features the problem becomes highly attractive in just-in-time environments. We introduce a depth-first branch-and-bound algorithm which makes use of extra precedence relations to resolve resource conflicts and relies on a fast recursive search algorithm for the unconstrained weighted earliness-tardiness problem to compute lower bounds. The procedure has been coded in Visual C++, version 4.0 under Windows NT and has been validated on a randomly generated problem set.

Observations of wintering Snowy Owls (Nyctea scandiaca) at Logan Airport, East Boston, Massachusetts from 1981-1997

Snowy Owls (Nyctea scandiaca) wintering at Logan International Airport were studied over the 15-year period of 1981-1997. Two-hundred twenty-seven Snowy Owls were banded and color-marked to examine the length of time individual birds stayed at this location and to track the movements elsewhere. Fifty-six owls were re-observed outside of the airport vicinity, and 11 of these were observed more than 150 km away. Dietary preferences based on observations of hunting and feeding owls recorded a total of 192 individuals of 35 species or species types. Educational programs are an important part of the ongoing research effort underway at the airport.
ENHANCE THE UNDERSTANDING OF PERIODIC TABLE OF ELEMENT USING CROSSWORD PUZZLES AMONG FORM 4 STUDENTS

In this study, the researcher aimed to identify students’ level of understanding of the Periodic Table of Elements before and after using the crossword puzzles called Chem-PTE crossword puzzles. The quantitative approach was used as the methodology of this research and a pre-experimental base was applied to one group as the research design. 25 students were purposely selected as the respondents. The study started with a pre-test, followed by the implementation of Chem-PTE crossword puzzles for 3 lessons and subsequently ended with a post-test. Then, students’ achievement scores in both, pre-test and post-tests, were analysed with descriptive analysis and paired samples t-test by using SPSS software version 24.0. The analyses were conducted to obtain the mean values for both the pre-test and post-test and next to test whether there was a statistically significant difference before (pre-test) and after (post-test) using the Chem-PTE crossword puzzles. Furthermore, this research also examined students’ perspectives on the effectiveness of Chem-PTE crossword puzzles by using questionnaires. Overall, the findings showed that the use of Chem-PTE crossword puzzles had improved students’ level of understanding as there was an increase in students’ achievement scores in the post-test compared with students’ achievement scores in the pre-test. Subsequently, the paired sample t-test analysis also revealed statistically significant differences before (pre-test) and after (post-test) the use of Chem-PTE crossword puzzles. Lastly, almost all of the students provided positive feedback on the effectiveness of the Chem-PTE crossword puzzles in enhancing students’ understanding of the topic Periodic Table of Elements.
Introducing New Forms of Digital Money: Evidence from the Introducing New Forms of Digital Money: Evidence from the Laboratory Laboratory

Central banks may soon issue currencies that are entirely digital (CBDCs) and possibly interest-bearing. A strategic analytical framework is used to investigate this innovation in the laboratory, contrasting a traditional “plain” tokens baseline to treatments with “sophisticated” interest-bearing tokens. In the experiment, this theoretically beneﬁcial innovation precluded the emergence of a stable monetary system, reducing trade and welfare. Similar problems emerged when sophisticated tokens complemented or replaced plain tokens. This evidence underscores the advantages of combining theoretical with experimental investigation to provide insights for payments systems innovation and policy design.
SSL splitting and barnraising : cooperative caching with authenticity guarantees

SSL splitting is a cryptographic technique to guarantee that public data served by caching Web proxies is endorsed by the originating server. When a client makes a request, the trusted server generates a stream of authentication records and sends them to the untrusted proxy, which combines them with a stream of data records retrieved from its local cache. The combined stream is relayed to the client, a standard Web browser, which verifies the data’s integrity. Since the combined stream simulates a normal Secure Sockets Layer (SSL) [7] connection, SSL splitting works with unmodified browsers; however, since it does not provide confidentiality, it is appropriate for applications that require only authentication. The server must be linked to a patched version of the industry-standard OpenSSL library; no other server modifications are necessary. In experiments replaying two-hour access.log traces taken from LCS Web sites over a DSL link, SSL splitting reduces bandwidth consumption of the server by between 25% and 90% depending on the warmth of the cache and the redundancy of the trace. Uncached requests forwarded through the proxy exhibit latencies within approximately 5% of those of an unmodified SSL server. Thesis Supervisor: M.

Background : Epilepsy is a brain disorder characterized by recurrent attacks of seizures. A seizure is a sudden change of behavior due to a transient alteration in the electrical pattern of the brain. Since despite appropriate drug treatment, one-third of patients continue to have seizures, other treatment must be considered. Aim : This study aims at emphasizing the importance of epilepsy surgery in pediatrics by assessing surgical outcome as regard seizure freedom and surgical morbidity & mortality at Al-Azhar university hospitals. Patients and methods : Prospective study on 27 pediatric patients diagnosed as drug-resistant epilepsy, with 6 months to 1 year follow-up at least. Group A, 14 cases operated by corpus callosotomy, Group B, 10 cases underwent lesionectomy, and Group C, 3 cases underwent MST. Result : 15 cases become seizure free, and 6 cases have rare disabling seizure. Lesionectomy was better than corpus callosotomy in achieving seizure freedom, In Group A, 4 cases become seizure free in comparison to 9 cases in group B. 11 cases of patients in group A (78.6%) showed increase alertness in comparison to the clinical mentality before surgery. The complications that have occurred were transient and resolved shortly. Conclusion : Epilepsy surgery in childhood is effective & safe and needs must be considered once failed medical treatment to prevent cognitive delay. Even when complete seizure freedom is not achieved, a great decrease in frequency of seizures and number of AEDs is a remarkable result.

Humic matter and phytoplankton nutrient limitation in a changing environment

Climate change leads to increased inputs of terrestrial dissolved organic carbon (DOC) and associated nutrients to freshwaters, potentially affecting the risk for eutrophication. While the effect of higher DOC concentrations on primary productivity (PP) due to light attenuation and increased competition by bacteria is rather well studied, the effect of DOC on PP due to effects on nutrient availability is still unclear. Therefore, laboratory incubation experiments with natural phytoplankton communities were performed to investigate the effect of DOC on phytoplankton growth under different phosphorus (P) and iron (Fe) regimes, under exclusion of light and grazing effects. The experiments were conducted with water originating from two sites with differing DOC character within Lake Malaren, the third largest lake in Sweden. P (ambient, 50 μg L-1 added), Fe (ambient, 400 μg L-1 added) and DOC (low, ambient, high) concentrations were crossed in all possible combinations giving 12 different treatments. Chlorophyll a concentrations and initial and final chemical conditions were analysed after 7.5 days of incubation. Specific growth rates were by far highest in P addition treatments, showing that the phytoplankton community in Malaren was mainly limited by P. Simultaneous addition of P and Fe further stimulated algae growth, indicating a co-limitation of Fe and P. The addition of Fe alone had no or a negative effect on growth rates, which might be explained by a strong binding of P to precipitated Fe. The effect of DOC on primary production depends on nutrient regime. Under ambient P conditions, DOC enhanced growth rates, probably due to a concurrent increase in nutrients associated to DOC. Under P-rich conditions, higher DOC concentrations resulted in lower growth rates compared to ambient DOC treatments. Fe showed a significant interaction effect with DOC under ambient P conditions. The direction of this effect depends on DOC quality, indicating that the different chemical composition of DOC influences Fe bioavailability differently. To determine which DOC type has a higher binding capacity for Fe, more research in primarily Fe-limited systems is needed. The study shows that PP in Lake Malaren is mainly regulated by P and partly by Fe and DOC. Moreover it demonstrates that DOC affects the availability of Fe to phytoplankton. It is concluded that increased DOC concentrations result in higher primary productivity, but a lower sensitivity of phytoplankton to P inputs.
Environmental information coverage in Spanish media between 2018 and 2021

Climate change and the environment are issues that should involve all social agents with the capacity to act because of their vital importance for human subsistence. The media are one of them, but they are hesitant and unfocused on the issue. Delimiting the study sample to the period 2018-2021, the objective of this article is to identify the frequency and space or time devoted by the audiovisual media, television and radio, as well as the coverage they make of environmental issues. The methodology used will be a combination of quantitative and qualitative content analysis of the journalistic pieces broadcast in these media, focusing on the study of: two radio news programs, Radio Nacional España and Cadena Ser and two television news programs, Televisión Española and Telecinco. The intention of this research is to obtain a diagnosis of the environmental journalistic coverage for raising public awareness of the risk of environmental impact in this four-year period. It can be seen that in this four-year period, since the adhesion of a good number of Spanish media to the “Decalogue of recommendations for reporting on climate change”, there has been a gradual increase in the information published on the environment, but that this is still excessively based on major events and environmental catastrophes and often decontextualized and with little use of sources.
DISORDERS : FROM THE PAST TO THE FUTURE

Research on mathematical disorders and their brain mechanisms has a long tradition. This paper presents the history of the search for the mechanisms of aquired acalculia from the perspective of clinical neuropsychology. The classic typologies of this disorder formed by Berger and Hecaen are discussed, as well as modern trends in the research on specific arithmetic difficulties in children. The latest general models of number processing (McClo skey, Dehaene, Butterworth, Zorzi) constructed within cognitive neuropsychology are included. Recently, new technologies of neuroimaging are being applied in research carried out within clinical and experimental cognitive neuropsychology. Neuroimaging technology (fMRI, PET) opens up opportunities to study the neural basis of number processing. On the other hand, these methods must be employed with care and the conclusions should be drawn within a broader, biopsychosocial context. Otherwise, there is the risk that a person with disorders will be reduced solely to an object of experiments. Furthermore, the neuroimaging results may lead merely to the development of "neurophrenology. " Such tendencies in research raise questions about its methodological limitations.
The impact of national culture on project management in the Middle East

Most international corporations have to adopt to the requirements of globalisation by working in international joint ventures or international projects outside their well known home markets. The successful management of projects is an essential element aiming to cope with the complex challenges caused by cultural factors and other influences on the management of projects. Especially the Middle East as a cultural region has experienced a dynamic growth during the last decades, as many of the countries rich in oil and gas have heavily invested into their local infrastructure. Besides other factors, the impact of national culture on project management may lead to negative influences like project delays and project failure, or positive influences such as an increased communication. Based on the Hofstede dimensional framework this thesis is designed to investigate which cultural factors and other factors influence the PMBoK (PMI Body of Knowledge) knowledge areas while delivering projects in the Middle East. This empirical study is using a qualitative research approach in a multiple-case study design analysing six projects. The results clearly show that some characteristics of the Middle Eastern cultural context strongly determine the applicability of the PMBoK knowledge areas. Especially the interrelation of individualism (IDV) and power distance (PDI) reveals some new perspectives for project work in this region. The two case studies illustrate a strong increase in power distance if the project manager and the team member do not originate from the same cultural background. Additionally differences in time perception and the characteristics of the dimension long term orientation (LTO) result in fundamental differences for the application of the PMBoK processes. The findings help to develop a theoretical framework highlighting specific influences for PMBoK knowledge areas. The results of this thesis may form a basis for future researchers aiming to develop improved models for project management in the Middle East or other cultural regions. Finally, the theoretical franework developed herein is designed to help project practitioners to gain a better understanding of the specific challenges while working on the Arabian peninsula.
