Making Sense of the Soul’s Numbers. Middle Platonist Readings of Plato’s Divisio Animae
Authors: Petrucci Federico M. 
Published: April 2018

Abstract
The aim of this paper is to show that a new approach to Middle Platonist technical exegesis is both necessary and profitable, for it can shed light on the deep philosophical and methodological background of Middle Platonist exegesis as a whole. Through the exegesis of Plato’s divisio animae, the Middle Platonists wanted to establish specific ways of both demonstrating and conceiving Plato’s authority also in the field of harmonics. In particular, I shall take into account Platonists such as Plutarch, Theon, Nicomachus, and Severus, in order to show that: a) the Middle Platonist exegesis of Plato’s divisio animae is chiefly based on a literalist approach to Plato’s text, which is exploited in such a way as to make good technical sense of Plato’s divisio animae; b) in this way, Middle Platonists sought to establish Plato’s authority in the field of harmonics; c) this conception of authority is however controversial, for some Platonists (e.g., Theon) regarded him as the founder of very specific technical notions, while others (such as Plutarch, Nicomachus, and Severus) considered him the first to have established the general framework of Greek harmonics.
Operator Learning Approach for the Limited View Problem in Photoacoustic Tomography
Authors: Dreier Florian , Pereverzyev Jr Sergiy , Haltmeier Markus 
Published: April 2018

Abstract
In photoacoustic tomography, one is interested to recover the initial pressure distribution inside a tissue from the corresponding
measurements of the induced acoustic wave
on the boundary of a region enclosing the tissue.
In the limited view problem, the wave boundary measurements are given
on the part of the boundary,
whereas in the full view problem, the measurements are known on the whole boundary.
For the full view problem, there exist various fast and robust reconstruction methods. These methods give severe reconstruction
artifacts when they are applied directly to the limited view data.
One approach for reducing such artefacts is trying to extend the limited view data to the
whole region boundary, and then use existing reconstruction methods for the full view data.
In this paper, we propose an operator learning approach for constructing an
operator that gives an approximate extension of the limited view data. We consider the behavior of a reconstruction formula on the extended limited view data that is given
by our proposed approach. Approximation errors of our approach are analyzed.
We also present numerical results with the proposed extension approach supporting our theoretical analysis.

Non-English lingua franca? Mobility, market and ideologies of the Chinese language in Nepal
Authors: Sharma Bal Krishna 
Published: April 2018

AbstractAs China’s economy continues to grow, making it the largest economy in the world, there’s a noticeable boost in its outbound tourism. As a result, the importance of Mandarin Chinese as a lingua franca is growing in many tourism contexts around the world. The number of and need for multilingual tourism workers who can speak Chinese is growing. In this article, I discuss ideologies of the Chinese language in the context of Nepal’s tourism and related businesses. I present findings from interviews with learners and users of Chinese in Nepal who come from multiple domains of language work such as tour guides, hoteliers, vendors, and business people. I complement the analysis with ethnographic observations of public linguistic signage from major tourist destinations in Kathmandu. I organize the findings into three key themes: (1) the commodity value of Chinese for Nepalis in order to achieve economic gains, (2) the increasing symbolic power of the Chinese language as an international lingua franca, and (3) the value of the Chinese language for intercultural understanding between the people of these two countries. While articulating these complex language ideologies, Nepalis portray Chinese as non-English speakers and, by the same token, position themselves as competent speakers of the English language. The findings as a whole highlight the power, prestige and commodity value of Chinese in Nepal, regimenting another lingua franca alongside English in international tourism contexts.

Authors: Gol’dshtein Vladimir , Hurri-Syrjänen Ritva , Ukhlov Alexander 
Published: April 2018

Abstract
We study the variation of Neumann eigenvalues of the p-Laplace operator under quasiconformal perturbations of space domains. This study allows us to obtain the lower estimates of Neumann eigenvalues in fractal type domains. The proposed approach is based on the geometric theory of composition operators in connection with the quasiconformal mapping theory.

Published: April 2018

Abstract

Background
Continuous increase in drug resistance has hindered the control of malaria infection and resulted in multi-drug-resistant parasite strains. This, therefore, intensifies the search for alternative treatments with no or less side effects. Several histone deacetylase inhibitors have been characterised to possess anti-malaria activity; however, their further development as anti-malaria agents has not recorded much success. The present study investigated the anti-plasmodial activity of sodium acetate in Plasmodium berghei-infected mice, aiming at finding a better alternative source of malaria chemotherapy.

Methods
Thirty female Swiss albino mice were randomly distributed into six groups. Groups A (uninfected control) and B (infected control) received only distilled water. Group C (artesunate control) were infected and treated orally with 4 mg/kg artesunate on the first day, and subsequently 2 mg/kg artesunate. Groups D, E and F were infected and orally treated with 50, 100 and 200 mg/kg sodium acetate, respectively.

Results
Sodium acetate significantly lowered parasitaemia (p<0.05) after 4 days post-treatment, and the parasite inhibition rate of 68.5% at 50 mg/kg compared favourably with the 73.3% rate of artesunate. Similarly, administration of 50 mg/kg sodium acetate improved serum total cholesterol relatively better than artesunate. Our results also revealed that sodium acetate does not interfere with liver function, as there was no significant difference (p>0.05) in the serum activities of aspartate aminotransferase and alanine aminotransferase in both infected treated and uninfected mice.

Conclusions
This study shows that sodium acetate may be a safe alternative source of anti-malaria drugs. Its effect on the serum total cholesterol also predicts its ability in correcting malaria-induced metabolic syndromes.

Authors: Kavun Yusuf , Boztosun İsmail , Ðapo Haris , Maraş İsmail , Segebade Christian 
Published: April 2018

Abstract
A nuclear analytical technique, namely instrumental photon activation analysis (IPAA), was used to determine Sr and Ca concentrations in human teeth. This work was conducted using the first accelerator facility, an off-shelf clinical linear accelerator (cLINAC), in Turkey. The tooth samples supplied by the Akdeniz University Faculty of Dentistry were analyzed for determination of the Sr/Ca element ratio. The results were obtained to demonstrate the impact of socioeconomic changes on dietary habits. A calibration material (CM; a mixture of calcium and strontium oxides) was required for quantification of the analytical results. The tooth samples, together with the CM, were exposed to 18 MeV end-point energy bremsstrahlung photons from the cLINAC. Thereafter, the γ-ray spectra of the samples and the CM were obtained using high resolution γ spectroscopy. Variations in the Sr/Ca ratio in the teeth of patients fed with beef and fizzy beverages were investigated in this study.
Numerical algorithm based on implicit finite-difference schemes for analysis of dynamic processes in blocky media
Authors: Sadovskii Vladimir M. , Sadovskaya Oxana V. 
Published: April 2018

Abstract
Dynamic processes in block-structured media are described within the framework of a mathematical model where elastic blocks interact with each other through pliable interlayers possessing complex mechanical properties. The case of elastic interaction is considered, the effects of plasticity and viscoelastic shear in block interlayers are taken into account. We use the model of porous fluid-saturated material in interlayers in which pores collapse during sudden or prolonged application of compressive stresses. An implicit difference scheme is constructed for numerical implementation of the model based on principles for construction of Ivanov’s schemes with controlled energy dissipation. Using MPI (Message Passing Interface), we developed parallel software for modelling wave motion in a two-dimensional formulation. The results of numerical analysis are presented for the waves initiated by rotation of blocks, which indicates a strong anisotropy of the blocky medium.

Published: April 2018

O objetivo deste estudo foi analisar o “estado da arte” acerca do comportamento sedentário em escolares no período entre 2012-2014. As bases de dados utilizadas para a pesquisa foram Biblioteca Virtual em Saúde (BVS) e Scielo - Scientific Electronic Library Online. O termo “comportamento sedentário” foi usado na busca inicial, sendo o resultado refinado posteriormente em “artigos”, “português”, “2012-2014”. Dois autores realizaram a leitura de títulos dos artigos de forma independente. Cinco artigos foram incluídos no estado da arte. Os artigos encontrados abordavam dois temas principais: fatores associados ao comportamento sedentário e validade e reprodutibilidade de questionários para avaliação do comportamento sedentário. Percebe-se que não há padronização na literatura acerca dos marcadores utilizados para caracterizar o comportamento sedentário. Também não há consenso em relação a qual tempo de exposição ao comportamento sedentário poderia estar associado aos efeitos deletérios à saúde dos escolares.

Published: April 2018

Since technology permeates every aspect of contemporary life, just navigating Higher Education (HE) in the 21st century makes you, to an extent, ‘tech savvy’. However, when looking to technology to assist student/staff partnerships, colleagues need to take their practice beyond Microsoft Office, social media and Photoshop.During a student/staff partnership research project, a student and a higher education professional used the online platform Padlet as their selected medium for collaboration, in order to replicate such of Healy’s principles of partnership as inclusivity, reciprocity, trust and community (Healy et al., 2014).

Published: April 2018

Abstract
A single well biopolymer injection test has been performed to investigate the stability of the biopolymer Schizophyllan under reservoir conditions. Laboratory tests of the Schizophyllan biopolymer prior to field test did show microbial degradation, and an environmentally qualified biocide was selected to be injected together with the biopolymer.
The objective of this paper is to focus on the microbial aspects of using biopolymers for EOR (Enhanced Oil Recovery) by performing an extensive microbial analysis program of injected and produced water samples both prior to and after injection of the biopolymer into the reservoir.
Multiple samples at different stages during the field test were collected using sterile and anaerobic methods to investigate any change in microbial community and evaluate any microbial degradation of the biopolymer.
Analyses show that the biopolymer was not biodegraded during the shut-in period due to presence of biocide. However, microbes able to degrade the biopolymer Schizophyllan were present and could have biodegraded the biopolymer in the absence of active biocide. The microbial community changed in the area affected by biopolymer injection during the field test.
