Adrianus van Selms
No full textAdrianus van Selms (1906-1984) was a Dutch pastor (1930-1938) who became senior lecturer and professor in Semitic languages at the University of Pretoria (1938-1972) and lecturer in Biblical archaeology (1938-1962) at the Faculty of Theology of the Nederduitsch Hervormde Kerk van Afrika (Dutch Reformed Church of Africa). He was an acknowledged academic in South Africa and abroad and the author of numerous publications. His books were predominantly in Dutch, but he wrote most of his articles in English, thus they are theoretically accessible to the scholarly public.
A number of articles, however, were published in Dutch and Afrikaans, dialects that are less easy to comprehend by those not familiar with the said two languages. The present book is an attempt to overcome the linguistic barrier and to present in a summarised way Van Selms’ contributions in three Dutch journals (Onder Eigen Vaandel, Nederlands Theologish Tijdschrift, and Kerk en Theologie), two academically-orientated Afrikaans journals (Hervormde Teologiese Studies and Acta Classica) and three journals of a more popular nature (Die Hervormer, Pro Veritate and Almanak). In total, 87 separate articles (discussed in 79 sections) of Van Selms receive attention
Adrianus Schrieckius : de la langue des Scythes à l'Europe linguistique
No full textThis paper presents a detailed analysis of the reasonnings of an author belonging to the Flemish School, Adrian von Schrieck or Schrieckius (1560-1621). His line of arguments is that of an historian of the indo-european civilization. He endeavours to show that the Scytho-celtic or Belgian tongue was the first to be found after the confusion of Babel. He carries out a segmentation of the word-forms of the original language; the resulting list of segments is then applied ta the words of various languages. These segments are therefore seen as universally recurrent forms.Pierre SWIGGERS: Adrianus Schrieckius De la langue des Scythes à l'Europe linguistique. Le but de cet article est d'examiner en détail l'argumentation d'un auteur de l'école flamande Adrian von Schrieck, ou Schrieckius (1560-1621). Schrieckius procède en historien de la civilisation indo-européenne; il s'efforce de montrer que la langue scytho-celtique ou belge a été la première langue après la confusion de Babel. Il opère une segmentation des formes des mots originaires; la liste des segments ainsi obtenus est alors comparée aux éléments des différentes langues. Les segments sont donc des formes universellement récurrentes.Swiggers Pierre. Adrianus Schrieckius : de la langue des Scythes à l'Europe linguistique.

From madrasah to museum : a biography of the Islamic manuscripts of Cape Town
No full textThis paper focuses on the Islamic manuscripts of Cape Town, locally referred to as kietaabs, written by Muslims predominantly in the 19th century, in jawi (Arabic-Malay) and Arabic-Afrikaans. Inspired by the idea of a 'biography' of the archive and 'the social life of things', the study traces the life of the kietaabs, from their creation and original use, to their role in contemporary South African society, as objects of heritage and identity. It approaches the kietaabs as objects, emphasizing their movements, status and use, rather than their content
Assessing the performance of the blue mussel (mytilus edulis) in an integrated multi-trophic aquaculture (IMTA) setting
No full textIntegrated multi-trophic aquaculture (IMTA) uses extractive organisms such as mussels to reduce wastes of fed organisms such as finfish and provide additional product for the growers. The physical and biochemical properties of Atlantic cod (Gadus morhua) wastes (feces and uneaten feed) were analyzed and the waste remediation potential and performance (growth and biochemical composition) of blue mussels (Mytilus edulis), were assessed. Waste generated daily by Atlantic cod represented 24.9% of the feed added to the system. Effluent was composed of particles <70 µm (36%), 70-500 µm (31%) and particles >500 µm (33%). Particles <70 µm had significantly less organic matter, lipids and fatty acids and were expected to be ingested more frequently by mussels. Effluent contained the fatty acid zooplankton markers (22: 1ω11 and 20: 1ω9) which accumulated in mussels. Effluent fed mussels had an inferior performance and contained significantly more MUFA, 18: 1ω9 and the NMID 20:2a as well as less ω3 than algae fed mussels. It is believed aquaculture wastes have potential as a diet supplement when natural seston is low.Bibliography: leaves 132-139
Improving the welfare of cultured low-trophic aquaculture species in a changing climate
No full textThe practice of growing low-trophic level species (LTA), primarily filter feeders, has been recognized for its sustainable food production potential while achieving the sustainable development goals set by the United Nations. However, LTA generally occurs in open systems where there is no control of the culture environment which leaves cultured organisms susceptible to climate change impacts. As invertebrates that cannot regulate their temperature and salt content LTA species are at the mercy of environment and climate change can impact their welfare. To better understand climate change welfare impacts on LTA species, we performed a risk assessment for Västra Götaland. As the first step in the risk assessment, we summarized the expected climate change impacts for Västra Götaland based on model projections from the Swedish Meterological and Hydrological Institute (SMHI). Additionally, physiological tolerance and expected responses for commercially important LTA species relevant to Västra Götaland were taken from the literature. Physiological tolerances were then compared with projected climate change impacts to develop a list of risks, both positive and negative. Each risk was evaluated in a consensus-based round-table expert workshop and prioritized based on stakeholder input in a separate workshop. Following the risk assessment, a short literature review was undertaken to identify possible adaptation actions. During our risk assessment we identified 22 climate mediated welfare risks for present day conditions that merit some form of adaptation or mitigation action. When considering future conditions, based on climate scenario RCP 8.5, the number of risks that required adaptation or mitigation actions roughly doubled, increasing by 22. Risks identified included, but were not limited to, direct effects such as extreme temperature and salinity as well as indirect effects such as changes to food availability. A risk management workshop with stakeholders and experts produced four recommended adaptation actions, prioritized based on their ease of implementation, potential impact, and number of effected risks: (1) More research to reduce uncertainties surrounding climate risks, (2) increased monitoring and modelling efforts to better predict and detect hazardous conditions as well as the development of emergency preparedness plans, (3) the capacity for submerging culture cages below the pycnocline temporarily to avoid hazardous surface conditions, and (4) more thorough and data-driven site selection to identify climate resilient culture areas

Sourcing and Evaluating the Use of Detritus as a Supplementary Diet for Bivalve Aquaculture Using Stable Isotopes and Fatty Acid Biomarkers
No full textDetritus is a ubiquitous component of ecosystems and an important fuel for secondary production. Due to the extractive nature of bivalve aquaculture, detritus is often incorporated into carrying capacity and growth models for cultured bivalves. However, despite the complexity and difficulty in obtaining direct measurements, detritus is often treated as a homogeneous food source in models. Further understanding the role detritus plays in the diet of cultured bivalves could lead to more comprehensive and accurate models as well as more informed site selection for growers. The purpose of this study was to assess the abundance, bioavailability, and contribution of detritus to the diet of a commercially important bivalve (Mytilus edulis) in a northern temperate bay (Saco Bay, ME USA) using a combination of lipid fatty acid biomarkers and stable isotopes (δ13C and δ15N). Both macroalgal (6.9 ± 0.1%) and vascular plant (4.8 ± 0.1%) detritus contributed to the particulate organic matter of Saco Bay and could supplement essential fatty acids (FA) or their precursors to consumers able to digest them. Mussels in Saco Bay may have been limited by the availability of the essential fatty acid 20:5ω3 (EPA) and incorporated macroalgal detritus as a small part (5 to 11%) of their diet. Macroalgae contained large proportions of the essential FAs 20:4ω6 (7 to 18%) and 20:5ω3 (8 to 25%) which may supplement the dietary needs of mussels. The original source of primary production had more influence on the bioavailability of lipid and FAs than the state of decay. The bioavailability of lipid and FAs from Ascophyllum nodosum (9 ± 3%) was significantly lower than that of Spartina alterniflora (56 ± 19%) and Isochrysis galbana (48 ± 2%), likely due to the presence of polyphenols and structural alginates that interfered with lipid solubilization. Although it contains essential FAs and its contribution into the diet of M. edulis suggest macroalgae could be a good supplemental diet for bivalve aquaculture, the concentration of secondary metabolites (\u3e3% wt/wt) and alginates needs to be considered due to their anti-nutritional effects
