Initial Plant Growth in Sand Mine Spoil Amended with Peat Moss and Fertilizer Under Greenhouse Conditions: Potential Species for Use in Reclamation
Get PDFThe Great Lakes Basin exhibits the largest collection of freshwater sand dunes in the world. Sand dunes are ecologically important and support a unique assemblage of flora and fauna. Sand dunes are also economically valuable. However, when sand dunes are mined, soil quality is drastically reduced. Therefore, soil quality improvements followed by revegetation maybe necessary for successful reclamation. This study evaluates the germination and initial growth of 2 legume species, sundial lupine (Lupinus perennis) and Illinois bundleflower (Desmanthus illinoensis), and 2 warm-season grass species, Indian grass (Sorghastrum nutans) and little bluestem (Schizachyrium scoparium), in the presence of 2 soil amendments (inorganic fertilizer and sphagnum peat moss) added to spoil from a local sand mine. We sowed species in pots and propagated them under greenhouse conditions. Results indicate that sundial lupine and Illinois bundleflower exhibited the greatest germination and growth among species. Peat moss had the greatest overall impact on germination and growth while the addition of fertilizer positively affected initial growth. Based on these results, sundial lupine is recognized as a primary candidate for sand mine reclamation, while Illinois bundleflower is also recommended as an appropriate species for revegetation efforts. We recommend using soil amendments that are functionally equivalent to peat in increasing soil water holding capacity. We further suggest that fertilization may be accomplished by including legumes in plant species mixes used for revegetation. Results presented here may help to identify appropriate species and soil amendments for the reclamation of former sand mines or restoration of freshwater sand dunes
Mathematics to touch, see and hear : how to explain the world of numbers to children with trisomy 21
No full textDie Mathematik ist eine allgegenwärtige Wissenschaft, die unser tägliches Leben beeinflusst. Um selbstständige und kritische Menschen zu erziehen, ist es wichtig, dass mathematische Konzepte in der Schule und zu Hause vermittelt werden. Eine gute Rechenfähigkeit ist im Alltag unerlässlich, da Zahlen überall präsent sind. Kinder mit Trisomie 21 haben nicht automatisch Dyskalkulie, sondern können ein Verständnis von Zahlen aufbauen. In dieser Masterarbeit wird untersucht, wie Lehrkräfte der Sekundarstufe 1 Kinder mit Trisomie 21 im Mathematikunterricht unterstützen können, um Rechenschwierigkeiten entgegenzuwirken. Die Ergebnisse internationaler Studien zeigen, dass mehr Forschung in diesem Bereich benötigt wird. Eine inklusive Schulbildung und verschiedenste Lernmaterialien sind Beispiele für Fördermöglichkeiten für diese Lernenden. Jedoch gibt es immer noch einen Mangel an Anleitungen wie Lehrkräfte Kinder mit Trisomie bestmöglich fördern können. Zusätzlich wird das Thema Rechenschwäche oder Dyskalkulie bei Kindern mit Trisomie 21 in dieser Masterarbeit genauer untersucht. Experteninterviews mit Lehrkräften und der Leiterin eines Down-Syndrom-Zentrums wurden durchgeführt, um den Praxisbezug zur Schule zu erforschen. Wichtige Erkenntnisse aus der Untersuchung sind, dass sich die Lehrkräfte intensiv mit verschiedenen Lernbesonderheiten auseinandersetzen müssen, um den maximalen Lernerfolg zu ermöglichen und die Kinder mit Trisomie 21 auf den Alltag vorzubereiten. Es ist deswegen besonders wichtig, den Unterricht lernendenzentriert zu gestalten. Grundsätzlich lässt sich sagen, dass Kinder mit Trisomie 21 mit der Hilfe von visuelle Lernangebote und Lernmaterialien höhere Lernerfolge erzielen können.Mathematics is an omnipresent science that influences our daily lives. To educate and raise independent and critical individuals, it is important to teach mathematical concepts in schools and at home. Proficiency in calculations is essential in everyday life since numbers are present everywhere. It is important to mention that Children with Down syndrome (Trisomy 21) can possess an understanding of numbers. My research question explores how teachers of secondary education can support children with down syndrome in mathematics classes to counteract arithmetic difficulties. The results of international studies indicate the necessity for more research, particularly regarding the mathematical development of children with down syndrome. Major findings of my study were that inclusive education and visual learning materials have expanded opportunities for these children, but that there is still a lack of guidance for teachers. Furthermore, the research gap regarding arithmetic difficulties in children with down syndrome is being examined in this master's thesis. Expert interviews with teachers and the head of a Down syndrome center were conducted to explore the practical implications in schools. Teachers must address various learning differences to ensure maximum learning success and to prepare them for their daily lives. That is why it is highly important to create a learner-centered approach to instruction. Overall, it can be said that children with down syndrome can achieve higher learning successes with the help of visual learning opportunities and learning materials.Abweichender Titel laut Übersetzung des Verfassers/der VerfasserinMasterarbeit Universität Graz 2023Zusammenfassungen auf Deutsch und Englisc

Vadon’ (MRAC). 1spm ‘COLL. MUS. TERVUREN | N.E. Madagascar: | Ambodivoangy 1959 | J. Vadon’ (MRAC). Differential diagnosis Ps. simoni differs by its short oval habitus and the short, stout parameres that are fused with the basal piece from all other African Psammoecus. The wide-based pronotal teeth resemble Ps. luchti sp. nov., it differs by the elytral striae being considerably wider than interstices, elytra being shorter, darkened basis of elytra, parameres short, stout and fused with basal piece. Redescription BODY. Oval, total length 2.13-3.00 mm (Fig. 11A). Surface yellowish-brown, sometimes reddish-brown, elytra with brown or blackish-brown maculae: humeral swelling, a transverse band in the middle of the elytra, the elytral suture along the posterior two thirds and the elytral apex are dark. Base of antennae yellowish or reddish brown, 6 th to 10 th antennomere darkened, 11 th antennomere yellowish-white, some specimens with light apex of 10 th antennomere. HEAD. Broad, temples narrowed immediately behind eyes; width 0.64-0.71 mm, length 0.33-0.44 mm, 1.67-1.73 times as wide as long. Eyes protuberant, rounded, 0.17-0.20 mm long, distance of inner margins 0.38-0.45 mm. Puncturation on vertex coarse, density of punctures variable, pubescence composed of long, semierect setae, directed anteriorly; microsculpture absent. Longitudinal impressions on vertex very shallow, attaining the middle of the eyes, sometimes shorter. Antennae as in Fig. 11B, 1.17-1.40 mm long, stout, antennomere proportions of lectotype as follows: 2.9: 1.3: 1.8: 1.5: 1.8: 1.6: 1.4: 1.0:1.2: 1.4: 2.8. PRONOTUM. Broad; width 0.62-0.74 mm, length 0.48-0.56 mm, 1.22-1.35 times as wide as long. Surface smooth, without impressions. Anterior angles with distinct groups of small teeth; lateral margins with four distinct teeth; tooth I very small, tooth II a little larger, teeth III and IV largest. Posterior group of teeth consisting of a larger anterior tooth and a very small, almost obtuse posterior tooth. Puncturation coarser than on vertex, punctures sometimes adjoining. Pubescence as on vertex; microsculpture absent. ELYTRA. Oval, short, length 1.35-1.70 mm, combined width 1.00- 1.23 mm, 1.27-1.43 times as long as their combined width. Rows of punctures on disc wider than interstices. Pubescence consists of long, semierect setae. Microsculpture absent. PARAMERES. Short, stout, fused with basal piece; with distinct pattern of three large setae (Fig. 11 C). Remarks In his original description, Grouvelle (1892) spells the name ‘simonis’. However, on the labels that Grouvelle added to the syntypes as well as in a later paper (Grouvelle, 1908c), he spells the name ‘simoni’. Pal (1985) also uses the latter spelling. Hence the present author considers ‘simonis’ to be a misprint and proposes to spell the name in accordance with Grouvelle (1908c) and Pal (1985).Published as part of Karner, Michael, 2012, A revision of African Psammoecus (Coleoptera, Silvanidae) and descriptions of two new species from the collection of the Musée royal de l'Afrique centrale, pp. 1-31 in European Journal of Taxonomy 17 on pages 24-26, DOI: 10.5852/ejt.2012.17, http://zenodo.org/record/385784
From Interspace To Interface: Shaping Public Life
No full textSome public spaces in the Netherlands function exceptionally well and provide significant benefit to the wider society in areas such as public health, retail activity and community participation. However, the vast majority of public space does not perform as well. One example is Oude Noorden, where the public space has failed to provide a noticeable benefit for the community and contribute to a separation between the different cultural groups within the multicultural neighbourhood. Moreover, the transition zones between public and private spaces are absent or do not work well and this results in social disconnection and poor public life. This thesis looks at the question of how spatial interventions can enhance the quality and increase public life of public spaces within a multi-cultural neighbourhood like Oude Noorden in Rotterdam. I particularly look at the design of the intermediate zone between public and private spaces, named as interface. Architects create urban areas by situating an imposing structure and the public and private spaces occurs as leftover spaces. However, it is precisely this space that is one of the main components that influence public life in-between buildings and shape our movements and behaviour. I developed design criteria that can be translated to other contents and locations to create a successful public space and increase public life.Design of the Urban FabricUrbanismArchitecture and The Built Environmen
