Abstract.We evaluated the performance of a commercial rapid diagnostic test (RDT) in a field setting for the diagnosis of abdominal cystic echinococcosis (CE) using sera collected during an ultrasound population screening in a highly endemic region of the Peruvian Andes. Abdominal CE was investigated by ultrasonography. Sera collected from individuals with abdominal CE (cases) and age- and gender-matched volunteers with no abdominal CE (controls) were tested independently in two laboratories (Peru and Italy) using the VIRapid® HYDATIDOSIS RDT and RIDASCREEN® Echinococcus IgG enzyme-linked immunosorbent assay. Performance indexes of single and serially combined tests were calculated and applied to hypothetical screening and clinical scenarios. Test concordance was also evaluated. Prevalence of abdominal CE was 6.00% (33 of 546) by ultrasound. Serum was obtained from 33 cases and 81 controls. The VIRapid test showed similar sensitivity (76% versus 74%) and lower specificity (79% versus 96%) than results obtained in a hospital setting. RDTs showed better performance when excluding subjects reporting surgery for CE and if weak bands were considered negative. Concordance between tests was moderate to very good. In hypothetical screening scenarios, ultrasound alone or confirmed by RDTs provided more reliable prevalence figures than serology alone, which overestimated it by 5 to 20 times. In a simulation of case diagnosis with pre-test probability of CE of 50%, positive and negative post-test probabilities of the VIRapid test were 78% and 22%, respectively. The application of the VIRapid test alone would not be reliable for the assessment of population prevalence of CE, but could help clinical decision making in resource-limited settings.
Contractual agreements in Ghana's oil and gas industry: In whose interest?
Authors: Abraham Kow Kwegya Amissah 
Published: May 2021

This article examines the history, nature, scope and policy ramifications of the production sharing contract as the core contractual agreement guiding the Ghanaian petroleum sector. It discusses the policy linkages between this form of contractual agreement and the management of the country’s oil exploration activities from 2010 to 2014. The article assesses the extent to which Ghana, as a new oil exporting country, has sought to actualize its resource benefits through negotiated contracts and agreements as well as management policies. The article argues that better negotiated contractual agreements ensure maximum State benefits from oil exploration. Again, production monitoring, periodic evaluation and institutional capacity building are effective ways of securing greater profits from oil resources. Finally, better legal and policy frameworks will also guarantee prudent management of the oil revenues.Keywords: Contracts; policy-making; agreements; oil exploration and production; Ghana.

Published: May 2021

The 2030 Agenda for Sustainable Development which aims at the eradication of poverty by 2030 has as its fourth goal the need to ensure inclusive and equitable education for all. Nonetheless, less than two per cent of Persons with Disabilities (PWDs) in Ghana are able to attain higher education. The purpose of this study was to ascertain whether libraries, which are major components of Higher Education Institutions, are physically accessible to even the limited number of PWDs in such Institutions. This study was undertaken in 2015 using the Kwame Nkrumah University of Science and Technology, Kumasi (KNUST) in Ghana as a case study. A mixed method approach was used that involved a desk study, interviews and a physical audit of the KNUST Library System using a checklist developed from international accessibility standards. In all, 16 libraries were assessed. The study concluded that the libraries at KNUST were generally not physically accessible and this served as a deterrent to PWDs in their academic pursuits. Recommendations which include the need for retrofitting the libraries were made to help make the libraries accessible and in consequence help toward the attainment of the 2030 Agenda for Sustainable Development with respect to Ghana.Keywords: Accessibility; Higher Education Institutions; Libraries; Persons with disabilities (PWDs); Universal design principles

Corrosion and Hydrogen Permeation in H2S Environments with O2 Contamination, Part 3: The Impact of Acetate-Buffered Test Solution Chemistry
Authors: Joshi Gaurav R. , Deffo Ayagou Martien Duvall , Mendibide C. , Mai Tran Thi Tuyet , Tribollet Bernard , Kittel Jean 
Published: May 2021

This paper highlights the importance of considering the magnitude of acetate (ethanoate) species concentration on corrosion and hydrogen permeation rates, important factors associated with cracking initiation in steels for sour service qualification. Materials selection relies on standards, such as NACE TM0177 and NACE TM0284, which stipulate that oxygen pollution should be avoided during testing in H2S-containing media. The 5% NaCl test solutions in current standards are buffered using acetic acid (CH3COOH)/sodium acetate (CH3COONa) to fix the solution pH over long periods. In this third paper, as part of a series of articles that evaluate how oxygen entry modifies the corrosion of (and hydrogen permeation across) low alloy steel membranes in H2S-containing solutions, the effect that changing the solution chemistry has through testing X65 steel in different concentrations of acetic acid and sodium acetate in H2S-saturated 5% NaCl solutions, i.e., Solutions A and B (NACE TM0177-2016) and the high-strength line pipe (HLP) solution of NACE TM 0284-2016, is investigated. Increasing the total acetic acid + acetate concentration encourages a higher average X65 corrosion rate and longer-sustained hydrogen charging flux, assigned to the cathodic reaction rate enhancement by acetic acid and the iron solubilizing effects of acetates. Introducing 300 ppb of dissolved oxygen does not push the solution pH outside of the permitted error range but increases average X65 corrosion rates and, again, helps sustain hydrogen permeation flux for longer. Through an evaluation of the surface structure and electrochemical data, this appears to be due to an increase in the permeability and protectiveness of the troilite FeStroilite dominant scale and a possible acetic acid buffering of local pH increase at surface cathodic sites during corrosion. The HLP solution (at pH 3.5), with the highest acetic acid and acetate concentration, is the most aggressive. In this electrolyte, an iron sulfide overlayer structure is attained with an oxygen-rich inner layer between the metal substrate and a thick iron sulfide film.

The Hidden School

The EAAE Annual Conference of 2019 is titled ‘The Hidden School’, aiming to discuss an architecture school’s true character, the substance and the quality of architectural education in the broadest sense, and that which is beyond the stated curricula, yet — whether concretely manifested or subliminally perceived — embodies the culture of the school.
The Hidden School can be observed through a range of tacit aspects or conspicuous specificities which make the educational path a unique one. It is the content that can be embedded within the syllabus, learned informally, personified by educators, the attributes and activities of students, or the spaces it takes place in.
Bearing this in mind, reading between the curricular lines is crucial in evaluation, but is it possible to develop tools for the assessment of the ‘hidden’? If the hidden school exists in parallel or as a background process, a self-generated search for fundamental answers, and its interpretation, manifestation or legibility has a multitude of facets, how can these aspects be captured?
The conference, hosted in 2019 by the Faculty of Architecture in Zagreb, focuses upon the subliminal quality of architectural education, that which is beyond the stated curricula and is hard to document through quality evaluation procedures.
Introduction

This year, we are very thankful for the commitment and generous support of the University of Zagreb, whose efforts brought together the representatives of over 130 architecture schools from all over Europe here in the capital of Croatia. In this conference we will be able to open up perspectives for new projects, developments, commitments and important decisions.
Other oriented perfectionism, player-coach relationships and performance in tennis
Authors: Hollowell John , Buscombe Richard , Preston Andry 
Published: May 2021

Other oriented perfectionism describes a pre-occupation with the expectation that others will achieve excessively high standards of performance. Projecting unrealistic expectations on to each other in a player-coach dyad may disrupt the working relationship and impact on the athlete’s experience within the sport. This study uses Interpretive Phenomenological Analysis to explore, from the coach’s viewpoint, the effects of other oriented perfectionism in tennis coaching. After conducting semi-structured interviews with high level coaches from the United Kingdom, two superordinate themes emerged. ‘Negative effects of coaches’ other-oriented perfectionism’ and ‘Redefining perfectionism’. The findings of this study assist in highlighting areas for possible intervention as well as identifying avenues for future research.

Payudara seorang wanita yang menghasilkan ASI (air susu ibu) merupakan asupan nutrisi yang sangat baik dalam proses pertumbuhan dan perkembangan seorang bayi. Didalam ASI (air susu ibu) terkandung semua gizi yang sangat diperlukan oleh seorang bayi dalam pertumbuhannya dan perkembangannya yang sempurna dan merupakan asupan nutrisi yang terbaik bagi bayi. Saat bayi dalam keadaan sakit air susu ibu akan menjadi obat yang akan menyelamatkan jiwanya. Kecemasan yang dialami ibu nifas saat menyusui bayinya akan berdampak terhadap kurangnya isapan pada bayi dan akan berpengaruh terhadap kurangnya produksi ASI sehingga membuat ASI tidak lancar. Produksi ASI akan terus meningkat selama 6 bulan dengan rata-rata produksi ASI mencapai 700-800ml kemudian produksi ASI akan menurun setelah lebih dari 6 bulan pertama menjadi 500-600ml, salah satu metode yang dapat merangsang produksi ASI adalah dengan melakukan metode teknik hypnobreastfeeding. Tujuan penelitian ini adalah untuk mengetahui pengaruh teknik hypnobreastfeeding terhadap pengeluaran ASI pada ibu nifas di Puskesmas Kota Datar. Desain penelitian ini menggunakan metode pre-eksperimen dengan design one group pre-test dan post- test.
