The anaphorae of the liturgy of Sts. Addai and Mari and the Byzantine liturgy of St. Basil the great: a comparative study
While all Eucharistic anaphoras derive their primary significance from the Christ- event and Last Supper, each one also reflects and expresses a particular liturgical tradition within Christianity. Two important liturgies from antiquity that share several common similarities are the Anaphora of Sts. Addai and Mari and the Byzantine Anaphora of St. Basil the Great. A detailed analysis of the historical and linguistic idiosyncrasies of the two anaphoras shows that Addai and Mari is clearly the more ancient Eucharistic prayer, a product of an East Syrian environment with distinctive Semitic elements, that has led scholars to claim possible apostolic antiquity. On the other hand, Byzantine-Basil belongs to a larger family of anaphoras attributed to the Cappadocian Father himself or to some redactor(s) within his liturgical tradition, and primarily reflects hellenistic ideas. St. Basil's journeys to Egypt and Syria seem to be responsible for the production of a Coptic version of Basil, which shares some common elements with Addai and Mari. Also, the two 'hellenized' East Syrian liturgies of Theodore of Mopsuestia and Nestorius (including the Maronite anaphora Sharar), which are very similar to the content of Addai and Mari, may be partially credited for identifying points of contact between the East Syrian and Byzantine prayers. The purpose of this thesis is to analytically examine the Eucharistic prayers of Addai and Mari and Byzantine-Basil by breaking down both anaphoras into their constitutive sections (through textual juxtaposition) in order to determine and affirm their mutual influence. The methods used are verbal and structural comparison, historical contextualization, and theological comparison. Where applicable, sections from other related anaphoras are also compared against the two main texts. The study concludes that despite Addai and Mari and Byzantine-Basil's individual uniqueness in style and content, both nonetheless are representative of the original Christian Eucharistic tradition and have seemingly influenced each other's development throughout history

Rheology of flocculated kaolinite dispersions
© 2005 by The Korean Society of RheologyRheological characterisation of flocculated kaolinite pulps has been undertaken to elucidate particle interactions
underpinning the dewatering behaviour induced by flocculation with polyethylene oxide (PEO),
anionic polyacrylamide (PAM A) and their blends. Shear yield stress (τy) analysis indicated that polymer
mediated particle interactions were markedly amplified upon shear of PEO based pulps. In contrast, PAM
A based pulps showed a significant decrease in yield values upon shear. Steady stress measurements analysed
using a modified Ellis model indicated subtle differences between the respective linear viscoelastic plateaus
of the pulps. Furthermore, modified shear thinning behaviour was evident in PEO based pulps.
Estimation of elastic and viscous moduli (G', G'') was made using dynamic stress analysis for comparison
with values determined from vane measurements. Despite a noticeable difference in the magnitude of G'
between the two methods, similar trends indicating sheared PEO-based pulps to be more elastic than PAM
based pulps, were observed. Floc microstructural observations obtained in support of rheological properties
indicate that PEO flocculant induces significantly more compact particle aggregation within the clay pulps
under shear consistent with the yield stress data, in contrast to PAM A, or indeed unsheared PEO based
pulps. Consequentially, sheared PEO based pulps show significantly improved dewatering behaviour. The
implications of the results, potential benefits and drawbacks of flocculation with PEO and PAM A are discussed
with respect to improvements in current dewatering processes used in the minerals industry.A.J. McFarlane, J. Addai-Mensah and K. Bremmel

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Surface modification of diatomaceous earth silica microparticles with functional silanes for metal ions sorption
CHEMECA 2010Natural diatomaceous earth (DE) particles functionalized with 3-mercaptopropyltrimethoxysilane (MPTMS) with specific selectivity for heavy/noble metals have been prepared used as enhanced metal ion adsorbent. X-ray Photoelectron spectroscopy (XPS) analysis of the mercapto-DE products revealed that the functional group (-SH) was successfully introduced to the adsorbent surface. Studies involving the extraction of Au(III) ions from aqueous solutions by pristine and MPTMS modified DE products indicated strong initial metal ions concentration and pH dependency. The Au(III) adsorption kinetics and adsorption isotherms for the MPTMS modified DE particles for Au(III) observed to follow a pseudo-second-order reaction model and Langmuirian behaviour, respectively. The adsorption reached equilibrium within 60 min with a maximum adsorption capacity of 208 mg g-1, a value found to be reasonably good. The results show that with further optimisation, a cost effectived new and environmentally benign mercapto-DE based adsorbent suitable for removing metals from aqueous solutions can be produced.Yang Yu, Jonas Addai-Mensah, Dusan Losi
Contributions of urban periodic markets to sustainable rural development in Ghana: A rural web analysis
Available online 14 March 2023There is a limited theoretical understanding of the importance of urban periodic markets (UPMs) for sustainable rural development in sub-Saharan Africa. This paper explores the value of UPMs to sustainable rural development by employing the rural web technique. The specific objectives are to (1) describe the characteristics of UPMs in Ghana, and (2) assess the effects of UPMs on the six indicators of sustainable rural development proposed by the rural web technique. Surveys and interviews were used to collect primary data in villages both in Ghana’s more developed southern region and the less developed northern region. Our study finds that UPMs generate important socioeconomic interactions and enable cooperative marketing in both regions. UPMs shorten the food supply chains and create new types of rural-urban linkages, especially through farmers’ direct participation. Farmers from across Ghana noted that UPMs create employment opportunities, and in turn, provide access to varieties of goods that are not locally produced. In northern Ghana, farmers’ participation in UPMs enable cross-border trading with international buyers from Burkina Faso and Cote D’lvoire. The findings imply that the modernisation of UPMs could provide a critical pathway to achieving sustainable development objectives within rural Sub-Saharan Africa.Godfred Addai, Jungho Suh, Douglas Bardsle
