DECISION OF SYSTEM DYNAMICS PARAMETERS IN COMPLEX FLOW PASSAGE THROUGH CFD

A laminar flow resistance in a pipe is usually used as a representative model of flow resistance because it is convenient to use and often gives reasonable resistance value in a small size pipe under steady state condition. However, the laminar flow resistance model in a pipe is not applicable in an oil flow passage of a real circuit because a flow passage has complex shape in a real circuit. Furthermore, the mathematical model of fluid column in a pipe made in inviscid flow condition is often used as an inertial model in considering dynamic condition. In the real condition of operating oil-hydraulic circuit, the above mentioned two effects, a complex shape of flow passage and flow dynamic characteristics, appears in viscous flow condition. A new model or modeling method to include and solve these effects reasonably becomes necessary. A new modeling method using CFD is introduced in this paper.
How Students as Consumers Learn Information about New Products

The importance of understanding how consumers gather and evaluate information about the new products is essential for providers. This paper considers the student population as consumers and attempt to determine where students as consumers learn information about new products and their attitudes toward different sources of information. Research was conducted at the Polytechnic in Sibenik and comprised students of all majors and years of study. Results indicated that students as consumers utilize a wide variety of information sources to learn about new products. Thus gender, as a major social category, age and other determinants of consumer behaviour were also considered. It concludes with some important marketing implications.
COMPETITIVE STRATEGIES ADOPTED BY AIRTEL KENYA FOR CUSTOMER RETENTION

Customer retention has gained increased value among both goods and service providing firms. However although extensive research exist on the concept of customer retention and its measures and instruments, studies and research on how professional service firms retain their customers remain limited. The telecoms industry in Kenya, just like the rest of the world, is going through profound changes. In the past decade, technological advancement and regulatory restructuring have transformed the industry. New challenges including staff restructuring, which may cause dissatisfaction as changes caused by market liberalization. The objective of the study was to establish the effectiveness of competitive strategies adopted by Airtel Kenya for customer retention. The specific objectives of the study were to establish how brand visibility and service quality influence customer retention on Airtel Kenya. The study adopted the customer bonding theory, social exchange theory and relationship commitment theory. Descriptive survey method was applied in this research in attempting to describe and explain the effectiveness of strategies adopted by Airtel Kenya for customer retention, by using unstructured questionnaires to fully describe the phenomenon. The population 13 service centres shops in Nairobi, the call centre, customer relation management and online portal. The data was analysed using descriptive statistics and presented on tables. The study also applied regression analysis to establish the relationship between the dependent and the independent variables. The study also employed multiple regressions as an analytical tool to give more insight on the effect of competitive strategies on the customer retention at Airtel Kenya. The study found that the four variables had positive and statistically significant effect on customer retention. The study concluded that brand visibility, service quality, were a major determinant of customer retention. Based on the finding the study recommend that managers and various stakeholder should emphasize on the enhancing brand visibility and service quality in their organizations as this would create a good reputation of the firm hence customer retention. The study further recommends that both the Airtel and other communication firms should ensure that they come with communication strategies that will ensure retention of customers
The Choice of Non-Market Strategy for Private Express Enterprises in China

Due to the Internet era and the background of big data, the express industry in China is developing rapidly. In addition to China Post, private express enterprises in our country are also entering a period of vigorous development. However, private express enterprises are still facing many other problems besides the effectiveness of market economy during development. What’s more, the choice of non-market strategy of enterprises has attracted more and more attention, but few people have studied the behavior and image establishment of such enterprises in the face of the public and the media. In the process of using the non-market strategy, the enterprise must deal with the relationship with many stakeholders, in order to help itself to build a unique competitive advantage. Based on the analysis framework established by the enterprise gene theory, this paper makes a deep analysis of social public and media strategy adopted by private express enterprises in China. Taking Shunfeng enterprises as the research object, this paper systematically expounds the concrete manifestations of enterprise genetic mechanism in the development process of private express enterprises, as well as the impact of gene recombination on the choice of non-market strategy for enterprises.

Cephalometric Evaluation of Craniofacial Morphology in Pediatric Patients With
 Fully Diagnosed OSA With Distinct Sagittal Skeletal Malocclusions

Study Objectives: To establish whether craniofacial and nasopharyngeal morphology, assessed through lateral cephalometry, in children properly diagnosed with obstructive sleep apnea (OSA) differed from that of non-likely OSA control children stratified based on sagittal malocclusion and to evaluate if there is any association with apneahypopnea index (AHI) severity. Materials and Methods: Various cephalometric measurements were compared between 22 children (mean age 8.8) with nocturnal polysomnography (nPSG) diagnosed OSA that had already adeno-tonsillectomy and a control group of 20 nonlikely OSA children (mean age 9.2) based on a negative pediatric sleep questionnaire (PSQ) results matched for age, sex and sagittal malocclusion. Results: Statistically significant increases in Go-Me and Ba^SN dimensions were observed among OSA children when higher AHI values (4.5 and 4 mm), whereas ANSPNS dimension was significantly increased in the Class II sample according to OSA severity (3.5 mm). No significant differences were identified for any variables among Class III based on OSA severity. In comparison to controls, in Class II both the angle between palatal plane and anterior cranial base and the angle of the flexure of cranial base were significantly reduced in OSA children (0.36 and 2.3 mm). In addition, an increased thickness of the upper adenoid profile and a reduced dimension of upper pharynx were observed (3.2 and 2.1 mm). In Class III a shorter bony nasopharynx was statistically significant (3.2 mm). Conclusions: The OSA sample showed some distinct craniofacial features compared to a non-likely OSA group. These differences were not consistently located when sagittal malocclusion was considered.
Improved Health: Evidence from Breast Cancer Screening

Education, Information, and Improved Health: Evidence from Breast Cancer Screening While it is well known that education strongly predicts health, less is known as to why. One reason might be that education improves health-care decision making. In this paper we attempt to disentangle improved decision making from other effects of education, and to quantify how large an impact it has on both a patient’s demand for health services, and that demand’s sensitivity to objective risk factors. We do this by estimating a simple structural model of information acquisition and health decisions for data on women’s self-reported breast-cancer risk and screening behavior. This allows us to separately identify differences in the ability to process health information and differences in overall demand for health. Our results suggest that the observed education gradient in screening stems from a higher willingness-to-pay for health among the educated, but that the main reason why the educated respond more to risk factors in their screening decision is because they are much better informed about the risk factors they face.

Web-based experimental platform for sentiment analysis

An experimental platform is presented in the paper, which is used for the evaluation of various approaches of automatic sentiment analysis in financial texts. The platform provides an experimental environment which enables the user to quickly assess the behavior of various algorithms for sentiment detection in given text from an arbitrary HTML source. There is a basic sentiment word tagger and country tagger available to facilitate the preview of text under analysis. Development of the platform and the algorithms it hosts is still in progress and is intended for experimental purposes only. However, as it is implemented as a publicly available web application, it can find its use also in general public with an interest in sentiment revealing parts of HTML sources.
High Performance Twitter Sentiment Analysis Using CUDA Based Distance Kernel on GPUs

Sentiment analysis techniques are widely used for extracting feelings of users in different domains such as social media content, surveys, and user reviews. This is mostly performed by using classical text classification techniques. One of the major challenges in this field is having a large and sparse feature space that stems from sparse representation of texts. The high dimensionality of the feature space creates a serious problem in terms of time and performance for sentiment analysis. This is particularly important when selected classifier requires intense calculations as in k-NN. To cope with this problem, we used sentiment analysis techniques for Turkish Twitter feeds using the NVIDIA’s CUDA technology. We employed our CUDA-based distance kernel implementation for k-NN which is a widely used lazy classifier in this field. We conducted our experiments on four machines with different computing capacities in terms of GPU and CPU configuration to analyze the impact on speed-up.
POLARIMETRIC TORNADO DEBRIS SIGNATURE SPATIAL AND TEMPORAL CHARACTERISTICS

Debris lofted by tornadoes may be detected in polarimetric radar data, now available nation-wide. For the seventeen months from January 2012 – May 2013, data was examined for each tornado which occurred in the domain of an operational polarimetric WSR-88D. Presence or absence of a debris signature was recorded, as well as characteristics of the signature when present. Approximately 20% of all Storm Data tornado reports were associated with a debris signature, though this proportion varied widely by region. Signatures were more frequently seen with tornadoes rated higher on the Enhanced Fujita (EF) scale, associated with higher reported total property damage, when intercepted by the radar beam at lower elevation, and in tornadoes with longer single-county path length. Percent of tornadoes with a debris signature showed two peaks in occurrence. The first, in spring, was associated with a higher proportion of strong tornadoes, and the other, in fall, may be associated with higher natural debris availability. Areal extent of the debris signature generally increases with total reported property damage and, to a lesser extent, with EF-scale rating. This and future related work will provide operational meteorologists with a preliminary quantified look at typical characteristics of the polarimetric debris signature associated with tornadoes of varying characteristics.

Role of Human Factors Engineering in Improving Employment Outcomes among Cancer Survivors

What role will human factors engineers and return to work professionals play in addressing the needs of cancer survivors in return to work? The National Cancer Institute estimates that there are 10.1 million cancer survivors in the United States. of these, 3.8 million are working age adults (ages 20 to 64) (2005). Due to early detection and treatment improvements, the length of survival has increased. Unfortunately, survivors may experience short term and long term side effects (physical, psychosocial and cognitive changes, and fatigue) from treatment that result in functional limitations that may affect their work productivity or their ability to return or continue in the work place. Although the majority of human factors engineering/ergonomics and return to work research has focused on occupational injuries and illnesses, the application of this information to employment issues encountered by cancer survivors may be extremely beneficial.
Automatic Multi-Stepping Approach for Ice Predictions

Ice growth calculations are generally limited to a single step covering the entire icing exposure, with all relevant parameters taken as constant and calculated on the clean body. For large ice accretions, it can be necessary to recalculate the flow and icing parameters as their value vary when ice accretes. This procedure is known as multi-stepping and appears reasonable under rime and glaze ice type regimes. A manual multi-stepping ice calculation is generally possible. However, an automatic multi-stepping ice prediction is often difficult to obtain. The present paper describes the automatic multi-stepping procedure implemented in the ice prediction code ICECREMO. Results obtained on a three-dimensional airfoil are discussed and compared with experimental shapes from the literature. Limitations of the code have been identified and are being addressed within the ICECREMO2 project. Key-Words: Icing, ice accretion, multi-stepping, phase change, modelling
Prilling of API/fatty acid suspensions_ Processability and characterisation

Current study evaluated the processability and characteristics of prills made of an active pharmaceutical ingredient/fatty acid (API/FA) suspension instead of previously studied API/FA solutions to enlarge the application field of prilling. Metformin hydrochloride (MET) and paracetamol (PAR) were used as model APIs while both the effect of drug load (10–40%) and FA chain length (C14–C22) were evaluated. API/FA suspensions were processable on lab-scale prilling equipment without thermal degradation, nozzle obstruction or sedimentation in function of processing time. The collected prills were spherical (AR≥0.898) with a smooth surface (sphericity≥ 0.914) and a particle size of± 2.3mm and 2.4mm for MET and PAR prills, respectively, independent of drug load and/or FA chain length. In vitro drug release evaluation revealed a faster drug release at higher drug load, higher API water solubility and shorter FA chain length. Solid state characterisation via XRD and Raman spectroscopy showed that API and FA crystallinity was maintained after thermal processing via prilling and during storage. Evaluation of the similarity factor indicated a stable drug release (f2 > 50) from MET and PAR prills after 6months storage at 25 °C or 40 °C.
Rescuing the Media in Emerging Democracies through ICT

Several studies have shown the efficiency and pitfalls of ICT for mediating collective communication during political upheavals. However, little literature exists on understanding how the diversity of content generated through ICT empowers a free press when traditional media channels fail to expose the truth and promote public debate. This research aims to broaden our understanding of how ICT facilitate the exposure and interpretation of conditions in government institutions that go against public moralities – interpretations with the potential to mobilise thousands of individuals to protest. We engaged in an in-depth qualitative research using data from the Twittersphere. We conducted our study in the context of a Guatemalan tragedy in which 41 girls living in a state care home lost their lives. Our contribution to the literature is the understanding of how ICT enables the collective construction of meaning powerful enough to mobilise thousands of individuals in protest.
motosalen-Treated Donor T Cells Have Polyclonal ntigen-Specific Long-Term Function without raft-versus-Host Disease after Allogeneic one Marrow Transplantation

We have previously shown that amotosalen HCl (S-59 psoralen)–treated donor splenocytes, which have limited proliferative capacity in vitro, can protect major histocompatibility complex–mismatched bone marrow transplant (BMT) recipients from lethal murine cytomegalovirus infection without causing graft-versus-host disease. In this study, we further investigated the effects of amotosalen-treated donor T cells on immune reconstitution after allogeneic BMT. We were surprised to find that amotosalen-treated donor T cells persisted long-term in vivo, comprising 6% to 10% on average of the T-cell compartment of transplant recipients at 4 months after transplantation. Donor T cells derived from amotosalen-treated splenocytes were predominantly polyclonal CD44 CD8 memory T cells and were functionally active, synthesizing interferon in response to stimulation with murine cytomegalovirus antigen. Amotosalen-treated donor T cells, reisolated from BMT recipients’ spleens >4 months after transplantation, proliferated in vitro, thus indicating repair of amotosalen-mediated DNA cross-links. Compared with infusion of untreated donor splenocytes, amotosalen-treated cells enhanced thymopoiesis by bone marrow–derived stem cells in BMT recipients. However, amotosalen treatment abrogated the thymopoietic activity of lymphoid progenitor cells among the donor splenocytes. Thus, infusion of amotosalen-treated donor T cells produced rapid immune reconstitution after major histocompatibility complex–mismatched BMT by transferring long-lived polyclonal memory T cells with antiviral activity and also by enhancing bone marrow–derived thymopoiesis. This is a novel approach to adoptive immunotherapy in allogeneic BMT. © 2005 American Society for Blood and Marrow Transplantation
Institute of Agricultural Development in Central and Eastern Europe

Based on the analytical framework of the structure-conduct-performance paradigm of the theory of industrial organisation, the paper analyses those economic conditions that determine the degree of competitiveness in the Latvian dairy and milling industry. The analysis is based on information from milk and grain processing enterprises acquired through a survey carried out at the beginning of 1998. It is shown that the development of market conditions and market behaviour in the sectors examined has in general progressed. Privatisation in both sectors has been completed. While in the dairy sector the majority of processing enterprises were privatised as co-operatives, in the milling industry all enterprises have become closed joint-stock companies. Since the legal status of a co-operative has turned out to be quite problematic for enterprise restructuring, more and more dairy enterprises have started to change into joint-stock companies. Competition in the investigated processing sectors can be considered as functioning. However, in the dairy sector tendencies of stronger horizontal concentration can be observed. The majority of enterprises react in quite an active way to the market conditions. Procurement and marketing channels have been diversified, and considerable investments have been undertaken. Further investments, however, are impeded by high interest rates for credits. As for performance, quite a considerable differentiation between the enterprises in the considered branches could be shown. The main problems seen by the processors are the saturation of the domestic Latvian market, the lack of investment funds, the unstable legislation, the absence of any substantial support from the government, and, in the dairy sector, the low quality of the raw milk.
Importancia de la actuación docente frente a la política educativa regional en la explicación del rendimiento en PISA The importance of teaching practices in relation to regional educational policies in explaining PISA achievement

Among the variables that explain schools and students' performances as measured in PISA stand out those that provide information about the social, economic and cultural context. These factors are non-malleable and are not within educational agents' reach. So that, once the effect of the socioeconomic context on assessment was controlled, we focused the study on the role that variables related to educational regional policy, to schools' institutional culture and to the teaching practices play on schools performance in PISA. For this purpose we carried out a secondary analysis with data of 976 secondary schools distributed along the 17 regions of Spain participating in PISA-2015 assessment cycle, and also with data about public/private enrolment, educational spending and available resources of the regional systems. We have built successive multilevel regression models -through a hierarchical linear analysisin order to know the role of schools and educational policy of all the Spanish regions on the explanation of schools' scientific competence. Findings focused on educational policy variables show that student-teacher ratio and the quantity of computers by classroom do matter on achievement. About the incidence on the performance of schools’ variables we found out that the school climate and the teaching practices have significant effects on outcomes. Students’ disruptive behaviour and teachers’ disrespectful interaction with pupils are both variables related to a lower level of competence. Nevertheless, efficacy in the classroom management, a direct teaching approach and the adaptation of the teaching activities to students’ needs are variables related to a higher level of competence. Students’ support and feedback exists when a low-level of scientific competence is founded. Finally, some proposals have emerged from these findings in order to do better at schools and to redirect educational policy.
