Timbre Solfege and Auditory Profile Analysis

A course in auditory evaluation of sound, called Timbre Solfege, was developed by a team of researchers headed by Professor Andrzej Rakowski, at the Music Acoustics Laboratory, Chopin University of Music. A large part of the course, taught at the Department of Sound Engineering, has been focused on the detection and identification of timbre changes produced by formants and by other kind of sound spectrum modifications. Detecting formants in sound recordings is an auditory task that has much in common with auditory profile analysis, an area of research initiated and developed in psychoacoustics by Professor David M. Green, exploring the fundamentals of detection of changes in the sound spectrum envelope shape, independently of the differences in loudness between the sounds. The purpose of this study is an attempt to relate the results of the Timbre Solfege sound evaluation drills to the theory of the auditory profile analysis.
Relationship between the customer expectations from websites performance and e-wom: a study on sport shoes brands

Purpose- Investigating the relationships among perceived website quality, sources of credibility, experience, social impact, and recommendation affect performance expectations, customer satisfaction, trust and WOM. Methodology- The data were gathered by personal interview and Structural Equation Modeling was used to test the relationships. Findings- The quality of the website content and the technological quality of the website have a positive impact on performance expectancy, while the website information quality has a negative impact on performance expectancy. The impact of adopting social impact and recommendations, the internet and past experience, sources of credibility on performance expectations were found insignificant. The impact of performance expectations on customer satisfaction and trust was found significant. The impact of performance expectancy on WOM was found insignificant. The direct impact of customer satisfaction on WOM was found significant. Conclusion- Technology or technological innovations that benefit customers or help their goals affect customer performance expectations. In the market conditions where the competition is rapidly increasing, it is an important element in terms of competition that the brands increase the performance expectations of consumers by attaching importance to the content quality and technical quality of the website. Increased performance expectation positively affects increased customer satisfaction and confidence in the website. In addition, customer satisfaction has a positive impact on word-of-mouth communication by enabling customers to have positive feelings and thoughts about the brand.
Larval settlement of the tropical abalone, Haliotis asinina Linnaeus, using natural and artificial chemical inducers

Many kinds of chemical and biological materials have been used as inducers of settlement of abalone larvae, as well as other species of marine gastropods, with responses being highly variable, even to the same chemical cue. The present study tested chemical inducers, γ-aminobutyric acid (GABA), δ-aminovaleric acid (5-AVA) and l-glutamic acid (GA) and the effects they have on larval settlement of Haliotis asinina. Additionally, a relatively inexpensive commercial substance, monosodium glutamate (MSG), was trialed. The datum provided shows all chemicals to be active inducers of settlement in this study, in order of effectiveness of 5-AVA, GABA, MSG to GA. Induction as adjudged from larval numbers settled was best at 6 h 62%, with 10−1 mM 5-AVA. At 24 h, induction was the highest at 78% when exposed to 10−2 mM 5-AVA. Larvae that were allowed to settle up to 72 h showed the highest numbers of settled larvae, and declined back to 60% when exposed to 10−2 5-AVA and 10−1 mM GABA respectively. Monosodium glutamate, although third in settlement standings would bypass the other chemicals, with regard to cost versus yield. The assessment of settlement surface, rough or smooth proved to be irrelevant, which had no significant impact on larval settlement.
Molecular genetics of dilated cardiomyopathy in the Dobermann dog

Canine dilated cardiomyopathy (DCM) is a disease of the myocardium associated with dilatation and impaired contraction of the ventricles. It primarily affects large and giant breed dogs with Dobermanns being one of the most frequently affected. The high prevalence of DCM in specific breeds suggests a genetic background, but causal mutations have not yet been identified. The main objective of the study described in this thesis was to identify the gene(s) involved in DCM in the Dobermann. For that purpose, the genes of interest were evaluated. Due to close similarities in human and canine DCM, mutated genes identified to cause DCM in the human are good candidate genes for DCM in dogs. At the outset of the DCM research project in 2001, most of the DCM candidate genes had not yet been mapped and the dog genome resources were limited. Therefore, bacterial artificial chromosome (BAC) clones carrying the genes of interest were isolated from the canine BAC library. Microsatellite markers isolated from the BAC clones were typed in the Dobermanns and evaluated for association with the DCM phenotype. While the genes encoding desmin, phospholamban, ? -tropomyosin and ? -sarcoglycan were excluded as DCM causing genes, the genotyping results of the titin markers point to a crucial role of titin in DCM susceptibility. The genetic markers and sequencing oligonucleotide primers reported in this thesis are tools that will enable fast evaluation of the DCM candidate genes in breeds other than the Dobermann. Further research into the role of the titin in canine DCM will also lead to better understanding of cardiomyocyte physiology and pathophysiology of DCM.

Factors affecting user intention in continuous interaction: A structural model

: The emergence of a variety of digital devices has changed the way people interact with digital services. Continuous interaction is considered to be one of the important interactions in multi-screen services. Therefore, this study aims to identify the factors affecting people's acceptance of multi-screen services in continuous interaction. A research model was constructed based on the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB) to conceptualize continuous interaction with user intention and to reveal significant relationships with behavioral constructs. Data collected from 203 multi-screen users were used to test the proposed research model. The result identified perceived synchronization and perceived seamless migration in continuous interaction as two important determinants in continuous interaction. Also, the model in this study demonstrated how continuous interaction affects user intention and the results indicated that among all factors, perceived seamless migration, perceived usefulness and user attitude are the strongest predictors that influence the decision to use multi-screen services. To conclude, this study is important in finding the gaps between continuous interaction and user intention, as well as in identifying areas for improvement when designing effective multi-screen services.
Dynamics of Research and Strategic Trading

We study how dynamic research affects information acquisition in financial markets. In our strategic trading model, the trader performs costly research to generate private information but does not always succeed. Optimal research activity responds to market conditions and generates novel implications. First, more frequent public disclosures can “crowd in” private information acquisition, increase price informativeness, and harm liquidity, instead of “leveling the playing field. ” Second, observed research activity does not necessarily imply that traders are better informed. Finally, improvements in research effectiveness or higher market participation by uninformed investors can simultaneously increase price informativeness and liquidity.
The advances in immunotherapy for hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the malignant tumors with higher incidence and mortality worldwide. Recently, significant progress has been made in uncovering immunotherapy in HCC, for instance programmed death-1, cytotoxic T-lymphocyte antigen 4, chimeric antigen receptor T-cell therapy, T cell receptor T cell therapy, dendritic cell vaccine, and cytokine-induced killer cells. This paper reviews the advances in immunotherapy and focuses on the results of many of preclinical studies and clinical trials in the field, as well as some of the promising therapeutic strategies for HCC in the future.
The Effects of Globalization on Social Development of Franc Zones Countries

This work aims to bring out the effects of economic and financial globalization on the unemployment rate evolution in the franc zone. We started to bring out the effects of globalization at the level of all the Franc Zone countries before making a comparative analysis between the CEMAC and the UEMOA zone. After having chosen the simple model at the end of the statistical tests for the regression at the level of all the countries of the Franc Zone, the results obtained showed that foreign direct investments (FDI) influence negatively and significantly the rate unemployment; just as the price index negatively influences the unemployment rate. These results indicate that FDI contributes to lower the unemployment rate in all the countries of the franc zone. As for other variables, they have positive effects and contribute to increasing the unemployment rate in the Franc Zone. Then, the results obtained from the comparative analysis between the CEMAC and the UEMOA Zone from the regression of a naive model, made it possible to note the diverging and converging effects between these two zones taken each separately on one hand and by comparing them to the results obtained at the global level on the other hand. In general, monetary, debt, trade and investment policies must be restructured in order to make them socially beneficial in the Franc Zone because in their current state, they seem to hinder the social development of this area.
The site of 1‐aminocyclopropane‐1‐carboxylic acid synthesis in senescing carnation petals

To study the cause of the uneven production of ethylene by upper and basal portions of detached petals of carnation (Dianthus caryophyllus L. cv. White Sim), the petals were divided and exposed to ethylene (30 μl 1-1 for 16 h). The treatment induced rapid wilting and autocatalytic ethylene production in the basal portion similar to that induced in entire petals. In contrast to the response in entire petals and the basal portions, the upper portions responded to ethylene by delayed wilting and much lower ethylene production. Aminocyclopropane carboxylic acid (ACC)-synthase activity in the basal portion of the petals was 38 to 400 times that in the upper portion. In untreated detached petal pieces from senescing carnation flowers, ethylene production by the upper portion declined after 6 h while the basal portion was still producing ethylene at a steady rate 18 h later. Application of ACC to the upper portion of senescing petals increased their ethylene production. α-Aminooxyacetic acid (0.5 mM), reduced the ethylene production of the senescing basal portion more than that of the upper portion. Endogenous ACC content in basal portions of senescing carnation petals was 3 to 4 times higher than in the upper parts. When detached senescing petals were divided immediately after detaching, the endogenous ACC levels in upper portions remained steady or declined during 24 h after division, while in the basal portions the ACC level rose steadily as in the intact petals. There was no change in the conjugated ACC in either portion after 24 h. Benzyladenine (BA) applied as a pretreatment to entire preclimacteric petals greatly reduced the development of ACC-synthase activity of the basal portion, but had little effect on the activity in the upper portion of the petal. In both portions, however, BA effectively reduced the conversion of ACC to ethylene.
Impact of Teachers Job Rotation on Students’ Academic Performance in Rivers State, Nigeria

This study examined the impact of teachers’ job rotation on students’ academic performance. In order to give proper dimensions to job rotation, interest, administrative knowledge, technical knowledge and business knowledge were used as necessary variables while the students’ grade (CGPA) was used to measure their academic performance. To sustain the empirical conclusion achieved, mean, standard deviation and Spearman’ rank order correlation coefficient (rho) and p-values obtained were used to analyze the data obtained in the course of this study. The study used responses which were obtained from 217 respondents which comprise teachers and academic best students from ten (10) public secondary schools in Port Harcourt and Obio/Akpor Local Government Areas of Rivers State. By available statistics from the National Population Commission (NPC) in 2009, those are the two most populated councils in Rivers State. The respondents were selected through a random process after proper stratification. The findings revealed a positive and significant relationship between the dimensions of job rotation and students’ academic performance (CGPA).
INDUCTION OF CDC25B FOLLOWING DNA DAMAGE: IMPLICATIONS FOR CELL CYCLE RESUMPTION AND TUMORIGENESIS

The overall hypothesis of this dissertation was that Cdc25B is an important regulator of the cellular response to DNA damage and defection from the normal response could promote tumorigenesis by enhancing genomic instability. Conventionally, DNA damage is generally thought to inhibit Cdc25 functionality to induce cell cycle arrest. However, recently a crucial role of Cdc25B in the cell cycle resumption after DNA damage was identified. To understand the precise regulation of Cdc25B following DNA damage, I examined the effect of mechanistically distinct DNA damaging agents on Cdc25B. Secondly, experiments were performed to elucidate how Cdc25B participates in the recovery from the checkpoints induced cell cycle arrest. Finally, the mechanism by which Cdc25B contributes to anti-BPDE induced tumorigenesis was investigated. The results of our studies revealed that Cdc25B was rapidly induced following DNA damage and levels of Cdc25B regulated the number of cells existing G2 into mitosis. Increased expression of Cdc25B did not affect the G2/M checkpoint engagement immediately following DNA damage; however, increased Cdc25B reduced the time required for cell cycle resumption. Using UV irradiation as the prototypic damaging agent, the increase in Cdc25B levels was found to be regulated by ATR/Chk1 via post-transcriptional mechanism, potentially by affecting Cdc25B protein stability. Furthermore, Cdc25B was found to be essential for anti-BPDE-induced neoplastic transformation. Additionally, Cdc25B facilitated resumption in the presence of DNA damage following anti-BPDE thus indicating that Cdc25B contributes to tumorigenesis by regulating premature recovery from checkpoints without completion of DNA repair. Finally, increased Cdc25B activated checkpoints in the absence of overt DNA damage suggesting that Cdc25B enables genomic instability by promoting selection of cells with deregulated checkpoint signaling. To conclude, studies presented in this dissertation identified a novel role of Cdc25B following DNA damage and elucidated the molecular mechanisms by which Cdc25B regulates anti-BPDE induced tumorigenesis.
NUMERICAL MODELING STUDY FOR FLOW PATTERN CHANGES INDUCED BY SINGLE GROYNE

Numerical modeling for single groyne in a rectangular section flume was developed to investigate flow pattern changes and to find the best performing installation interval. A threedimensional computational fluid dynamics model was built to simulate the flow properties near the groyne including the groyne tip velocity and the flow separation length. To evaluate hydraulic influences on the tip velocity and the separation length, four different ratios of groyne length to channel width and five different porous groynes were simulated over varied approach velocity in this study. Permeability of the groyne was reproduced by changing the gap between the cylinders. The approach water depths and the approach velocity acquired from the physical model were treated as the boundary conditions for the numerical model. Computed groyne tip velocity, the separation length, and two-dimensional velocity vectors were compared with the physical model measurements for validation of the numerical model. The numerical model computations showed very positive agreement with the physical model measurements. Relative error analysis showed that the numerical model agreed within 5 % of the physical model for up to 40 % groyne permeabilities. The relationship of the ratio of the computed separation length to groyne length with Froude number was presented and compared with the empirical equation suggested from the physical model. It was found that the numerical model can complement the physical model. The validated numerical model will be used to investigate the effects of the groyne installation angle, series of groynes, and curved channel application for future studies.
Transforming growth factor β1 and interleukin 4 induced α smooth muscle actin expression and myofibroblast-like differentiation in human synovial fibroblasts in vitro: modulation by basic fibroblast growth factor

OBJECTIVE To discover if α smooth muscle actin expression and myofibroblastic differentiation are induced in synovial fibroblasts by cytokines found in the inflamed RA joint. METHODS Immunofluorescent microscopy and western blotting were used to examine different cultures of human synovial fibroblasts for expression of α actin in the presence of the cytokines transforming growth factor β (TGFβ1), interleukin 1α (IL1α), IL4, IL6, tumour necrosis factor α (TNFα), and basic fibroblast growth factor (FGF). RESULTS A small but significant population of cells (14.4 ± 12.9%) expressed α actin under standard culture conditions. Upon treatment with TGFβ1 there was a pronounced increase in the number of cells expressing α actin (68.1 ± 5.49%), accompanied by a change in morphology to a myofibroblast-like phenotype. Other cytokines found within the inflamed joint such as IL1, TNFα , IL6, and basic FGF failed to induce α actin expression. However, IL4, which is normally absent or only present at low concentrations in the RA joint had a similar effect to TGFβ1. It was also found that basic FGF inhibited the induction of α actin expression by TGFβ1 and IL4. CONCLUSION In the presence of TGFβ1 or IL4, fibroblasts derived from synovial tissue or synovial fluid are induced to differentiate into myofibroblast-like cells containing the α smooth muscle form of actin. This differentiation is inhibited by basic FGF. It is suggested that the balance between these particular cytokines may be important in the modulation of fibroblast behaviour, which could have significant effects on joint repair mechanisms and the generation of fibrous tissue within the rheumatoid joint.
Stock Price Forecasting: Geometric Brownian Motion and Monte Carlo Simulation Techniques

This research paper aims to explore, compare and evaluate the predictive power of the Geometric Brownian Motion (GBM) and the Monte Carlo Simulation technique in forecasting the randomly selected 10 listed stocks in the SET50 of the Stock Exchange of Thailand (SET). The results shows that for the highest precision +/-0.5% of predicted 45 days return, the percentage of accuracy is at the highest of around 5% (or 500 times in 10,000 trials) for both GBM and Monte Carlo Simulation. It can be concluded that model accuracy in predicting end period returns is limited. Especially, predictive power of the models are declining towards the longer the evaluated timeframe. Comparing GBM and Monte Carlo Simulation in term of percentage of accuracy in predicting the end period returns, the two techniques are indifferent. For the predictive power of movements in prices, the GBM is a preferred technique. Besides, Monte Carlo Simulations yields a better accuracy especially in a longer period of evaluated timeframe. In conclusion, both techniques can predict stock prices within a highly accurate range. Thus, the techniques can be applied for stock price forecasting with limits mentioned. * E-mail address: nopmanee555@gmail.com Received: March 7, 2019 Revised: May 20, 2019 Accepted: May 30, 2019 วารสารบรหิารธุรกจิเทคโนโลยมีหานคร Volume 16 Number 1 (January – June 2019) 91
ANTIBIOTIC RESISTANCE AGAINST STAPHYLOCOCCAL ISOLATES RECOVERED FROM SUBCLINICAL MASTITIS IN THE NORTH OF PALESTINE

The antimicrobial resistance to 10 antibiotics was determined in 132 staphylococcal isolates. These representing Staphylococcus aureus (n=66) and Staphylococcus epidermidis (n=66). All isolates were from milk samples obtained from subclinical mastitis from Awassi ewes, local goats and Fresian cows. Results indicated that among all the antimicrobial agents tested the highest resistance of staphylococcal isolates was to ampicillin. The frequency of resistance to ampicillin was 75.8 and 66.7% against S. aureus and S. epidermidis isolates, respectively. Resistance to amikacin, cefepime, vancomycin, tobramycin or chloramphenicol was rare. None of staphylococcal isolates was susceptible to all tested antibiotics. Resistance to at least 3 drugs was found in (35) 53% and (28) 42.4 % of S. aureus and S. epidermidis isolates, respectively.
