Performance Analysis and Cavitation Prediction of Centrifugal Pump Using Various Working Fluids
Authors: Rehman Atiq Ur , Paul Akshoy Ranjan , Jain Anuj 
Published: September 2019

Background:
The application of centrifugal pumps is found in domestic and petrochemical
industries. Industrial centrifugal pumps are designed and tested using water as working fluid before
supplied to industries, as water is commonly available. However, centrifugal pumps are used in industries
for various applications, which involve the handling of fluids other than water- like saline-water,
crude oil, gasoline, etc. Consequently, hydraulic performance of the pump differs from the designed
and tested values and pump performance becomes unpredictable. Cavitation characteristics of the pump
handling different fluids other than water are also changed and many a time, cavitation starts prematurely.
As a result, the operating cost of pump is increased.

Objective:
A CFD based computational analysis of a single-stage, single-entry industrial centrifugal
pump having double-volute casing is carried out to compare the performance and cavitation characteristics
for various working fluids, namely water, saline water with varying salinity, gasolene and crude oil.

Methods:
Multiple Reference Frame method (MRF) available in Reynolds-Averaged Navier-Stokes
(RANS) equations based CFD solver Ansys-CFX is used in the present study. CFD simulation is carried
out for five flow rates with Standard k-ε turbulence model. Rayleigh-Plesset equation describing
the growth of a single vapor bubble in a liquid is used for predicting the cavitation flow behaviour.

Results:
Minimum static pressure is computed at the suction side of saline water as compared to the
other working fluids studied here. Hydraulic efficiency of crude oil is found to be the lowest as compared
to other fluids. Supercavitation (excessive formation of vapor bubbles and sudden drop in head
up to 3%) starts early for saline water with 40g/kg salinity.

Conclusion:
The results show little variation in pump efficiency when water and saline water are used
as working fluids. However, cavitation characteristics differ considerably with the working fluids. Recent
patents filed/published in this area revealed that efforts are needed to develop effective cavitationresistant
centrifugal impellers and pumps.
Archiving Collective Memories and (Dis)owning
Authors: Tchokothe Rémi Armand 
Published: September 2019

This paper investigates the question of ownership of collective memories in the age of digitized archiving. The United Nations Educational, Scientific and Cultural Organization’s (henceforth Unesco) philosophy of preserving the world cultural heritage has boosted research on African oral literatures. The emphasis on the documentation of endangered cultures of Africa is salutary but also raises some critical questions. The central question this contribution addresses is that of the authorship-ownership of cultural heritage that is being archived in the framework of digital humanities. In essence, the notion of “collective memories” entails that of collective authorship and collective belonging as these memories are passed on from one generation to the other without the claim of singular ownership. A significant example in this line of thought has been the observation by the cultural giant Amadou Hampâté Bâ who ironically pointed out that the real author of The Fortunes of Wangrin (1973), which is attributed to him, is actually the storyteller Wangrin – the cunning interpreter – and members of the whole literary tradition that Wangrin embodied. In the preface of a recently published volume on La question de l’auteur en littératures africaines (Jérôme Roger 2015: 16) the author asks the following pertinent question: how can African literature, both oral and others, invite scholars to rethink the relationship between the anonymity of sources, versions and variants of stories and the constraint for an author’s name imposed by editors? The question has more weight in view of the massive digitization of African oral literatures that mostly takes place in institutions with more economic prestige and which are located outside the African continent. Therefore, the interrogation centres on the role of power with regard to the form in which these (hi)stories are published, where, how and to whom they are accessible, and to the habit of researchers to name people from whom they receive the bulk of knowledge which they transcribe and translate into the academic jargon “informants” instead of giving them more credit by referring to them as research partners or even by recognising them as co-authors. In this vein, the paper rounds up by exploring the possibility of reversing the customary auctorial perspective by bringing into the discussion the idea of “researchers as griots” suggested by (Merolla, Ameka & Dorvlo 2013).

Published: September 2019

Objetivo. Evaluar la reducción de los niveles de proteína bruta sin alterar la relación de aminoácidos esenciales en pollos de engorde criollos de uno a 42 días de edad. Materiales y métodos. Se realizaron dos ensayos que comprendieron la fase inicial (un a 21 días) y crecimiento (22 a 42 días). Se utilizaron 630 pollos de la línea Redbro de un día de edad, distribuidos en un diseño completamente al azar, con cinco tratamientos y seis repeticiones de 21 aves cada una, totalizando 30 unidades experimentales distribuidas en corrales con buen abrigo. Los niveles reducidos de la proteína bruta para la fase inicial fueron: 21.5; 21.0; 20.5; 20.0 y 19.5% y para la fase de crecimiento: 19.0; 18.5; 18.0; 17.5 y 17.0%. En todos los tratamientos se mantuvo la proporción mínima entre aminoácidos esenciales y lisina. Las características de desempeño evaluadas fueron: ganancia de peso, consumo de alimento y conversión alimenticia. Resultados. No hubo diferencia (p>0.05) en la reducción de proteína bruta para ninguna de las fases, excepto para conversión alimenticia (p<0.05) en la fase de crecimiento que mejoró con 18.2% de proteína bruta. Conclusiones. Los niveles de proteína bruta para pollos criollos de engorde de la línea Redbro, pueden ser reducidos a 19.5 y 18.2% para la fases inicial y de crecimiento, respectivamente, siempre y cuando se mantengan las relaciones adecuadas de aminoácidos con lisina digestible y se atiendan las exigencias de los aminoácidos limitantes.

Published: September 2019

Background and objectives
The short-term effects of low-phosphate diets on fibroblast growth factor 23 (FGF23) level and the optimal amount of dietary phosphate restriction in patients undergoing hemodialysis remain unknown.

Design setting, participants, & measurements
This was a randomized, active-controlled trial with a crossover design that included 35 adults with ESKD undergoing thrice-weekly hemodialysis and with a serum phosphate level >5.5 mg/dl or between 3.5 and 5.5 mg/dl with regular phosphate binder use at a hemodialysis unit of tertiary teaching hospital in Taiwan. Subjects were randomized 1:1 to receive a very-low-phosphate diet, with a phosphate-to-protein ratio of 8 mg/g, or a low-phosphate diet, with a phosphate-to-protein ratio of 10 mg/g for 2 days, each with a 5-day washout during which subjects adhered to their usual diet. The primary outcome measure was mean difference in change-from-baseline intact FGF23 level between intervention groups. Secondary outcomes included difference in change-from-baseline serum phosphate, intact parathyroid hormone (PTH), and C-terminal FGF23 level between intervention groups.

Results
There was no significant difference in the mean change-from-baseline in intact FGF23 levels between the two study diets. The very-low-phosphate diet significantly lowered serum phosphate (mean difference, 0.6 mg/dl; 95% confidence interval [95% CI], 0.2 to 1.0; P=0.002). There were no significant differences in change-from-baseline intact PTH and C-terminal FGF23 levels between the two study diets.

Conclusions
Over the 2-day period, the FGF23-lowering effect of the very-low-phosphate diet is similar to that of the low-phosphate diet. The very-low-phosphate diet has an additional phosphate-lowering effect compared with the low-phosphate diet.

This research attempted to investigate whether the L2 learners have access to the Universal Grammar.KEYWORDS: Generative grammar. Principles and parameters. Second language acquisition. Null subject.
Beyond morphological use: what semantic knowledge tells us about aspect in L2 portuguese (Além do uso morfológico: o que o conhecimento semântico nos diz sobre o aspecto em português como L2)
Authors: Rothman Jason , Iverson Mike 
Published: September 2019

This study investigates the acquisition of [±perfective] aspect in L2 Portuguese via knowledge of the [± accidental] distinction that obtains between the Preterit and Imperfect in adverbially quantified sentences (LENCI; BERTINETTO, 2000; MENÉNDEZ-BENITO, 2002). Crucially, we show that intermediate L2 learners demonstrate phrasal semantic knowledge that we argue is accessed via the acquisition of new L2 features. As a result, we contend that the data support theories of adult UG-continuity (DUFFIELD; WHITE, 1999; SCHWARTZ; SPROUSE, 1996) and provide evidence in contra so-called Failed Features accounts of SLA (BECK, 1998; HAWKINS; CHAN, 1997). Furthermore, we discuss these data in light of probabilistic approaches to SLA, which interpret errors in morphological use at this level as evidence of underlying deficits in L2 mental representations. With others, we argue that morphological performance alone is neither a direct nor an exact measure of linguistic competence (PRÉVOST; WHITE, 2000; LARDIERE, 1998, 2006).KEYWORDSS: L2 acquisition. Aspect in L2 portuguese. Theories of adult UG-continuity.
RESUMO Esse estudo investiga a aquisição do aspecto [±perfeito] em português L2, mediante conhecimento da distinção [± acidental] que ocorre entre o pretérito perfeito e imperfeito em frases com quantificação adverbial (LENCI; BERTINETTO, 2000; MENÉNDEZ-BENITO, 2002). Mostramos que os aprendizes L2 intermediários demonstram conhecimento da semântica sintagmática, que conforme argumentamos é acessível por meio da aquisição de novos traços da L2. Como resultado, propomos que os dados dão suporte a teorias de continuidade da GU (DUFFIELD; WHITE, 1999; SCHWARTZ; SPROUSE, 1996) e oferecem evidência contra as assim chamadas propostas de Traços Malsucedidos (FAILED FEATURES; BECK, 1998; HAWKINS; CHAN, 1997) para ASL (aquisição de segunda língua). Além disso, discutimos tais dados considerando abordagens probabilísticas para ASL, que interpretam erros de uso morfológico nesse nível como evidência de déficits subjacentes das representações mentais de L2. Em consonância com outros autores, argumentamos que o desempenho morfológico não é por si só uma medida direta ou exata da competência linguística (PRÉVOST; WHITE, 2000; LARDIERE, 1998, 2006).PALAVRAS-CHAVES: Aquisição de L2.

Financial Statement Aggressiveness Related to Tax Accounts and Tax-Related Accounting Misstatements
Authors: Burton Hughlene A. , Tanyi Paul N. 
Published: September 2019

ABSTRACT
In this study, we examine two questions: (1) whether financial statement aggressiveness related to tax accounts is associated with the likelihood of having tax-related misstatements in the financial statements, and (2) whether the disclosure of the need to restate prior years' financial statements for a tax-related reason influences tax-related financial statement aggressiveness related to tax accounts in the fiscal year of announcement. Recent evidence of an increase in the rate of tax-related accounting restatements motivates these questions. In this study, we find empirical evidence suggesting that tax-related financial statement aggressiveness is positively associated with the likelihood of having tax-related misstatements in the financial statements. We also find that in the year in which the need to restate prior years' financial statements is announced, companies with tax-related misstatements in their financial statements appear to be less tax-related financial statement aggressive compared to the control group.
The Professional Ethics Exam and Acts Discreditable: An Introductory Assignment
Authors: Bordeman Adam , Westermann Kimberly D. 
Published: September 2019

ABSTRACT
This practice-oriented assignment familiarizes accounting students with their states' professional ethics exam and illustrates the disciplinary proceedings process resulting from failed ethics. Part I of the assignment requires students to research their states' professional ethics exam requirements. Part II of the assignment asks students to select current disciplinary actions, review the affiliated disciplinary proceedings, apply relevant sections of the AICPA Code of Professional Conduct, and evaluate the appropriateness of the consequences. Survey responses from 322 accounting students suggest that prior to this assignment most students are unaware of an ethics requirement for initial CPA licensure. Students perceive that the assignment effectively exposes them to the AICPA Code of Professional Conduct and violations experienced by practicing CPAs. The majority of students surveyed believe the assignment is valuable, interesting, enjoyable, and improves their understanding of “ethics in practice.”

Footprints of Lifelong Learners: Occupational Health and Safety Course
Authors: KİP KAYABAŞI Buket , AYDIN Sinan 
Published: September 2019

Lifelong
learning represents all learning activities undertaken throughout a person’s
lifetime, with the aim of improving knowledge, skills and competencies. These
activities can be undertaken in formal, non-formal as well as informal learning
settings. From this point of view, Anadolu University e-Certificate Programs
are national scale platform and have been developed as a solution to the need
for lifelong learning in Turkey.

In 2016,
upon the Ministry of Labour, Social Services and Family’s request, an OHS e-Certificate
Program for Employer and the Representative of Employer, who have a workforce
of fewer than 50 workers and a workplace
that is classified as “less dangerous” has been designed by Anadolu University.

This
research is designed to reveal the tendencies within the Occupational Health
and Safety e-Certificate Program, which has almost 80,000 participants since
2016. The average age of participants is 39 and 65.3% are graduates of higher
education and 51.4% are employers. Participants have indicated that they are
most likely to benefit from the course book during their study; 80.7% of them
stated that they will re-participate in such course which is conducted through
open and distance learning.
