A novel mutation in the β-protein coding region of the amyloid β-protein precursor (APP) gene

A novel mutation, a C to T transition at base pair 2124 in exon 17 of the amyloid beta-protein precursor (APP) gene, has been identified by direct sequencing of amplified DNA from two Alzheimer's disease (AD) patients. A simple oligonucleotide-hybridization procedure was developed to allow population studies of this DNA variation. The mutation, which is silent at the protein level, was present in

Biostratigraphical and palaeoecological significance of graptolites, trilobites and conodonts in the Middle-Upper Ordovician Anderso Shale: an unusual 'mixed facies' deposit in Jamtland, central Sweden

Although only about 20 m thick, the Anderso Shale contains one of the most diverse, if not the most diverse, late Middle-early Late Ordovician faunas known in Baltoscandia. It includes more than 20 trilobite species, more than 20 species of other shelly fossils, about 10 graptolite species, and about 20 conodont species. Based on its lithology, its geographical position near the foreland basin mar

It's Our Time to 'Chop': Do Elections in Africa Feed Neopatrimonialism rather than Counter-Act it?

This article addresses the concern that democratization may contribute to the reproduction of neo-patrimonialism, rather than to counteract it. The article reports the result of a survey among members of parliament in Ghana regarding their election campaigns. Total spending, sources of funds, and their usage are analysed in the context of the consolidation of liberal democracy. The survey results

Informal investors as entrepreneurs – the development of an entrepreneurial career

Informal investors have proved to be highly valuable for the growth of the firms in which they have invested. Therefore, it is important to understand what motivates potential informal investors to make their initial investment as well as how already active investors develop their entrepreneurial careers. Such an understanding may prove helpful in directing efforts to locate and attract potential

The Power of Elections : Democratic Participation, Competition and Legitimacy in Africa

Popular Abstract in Swedish Baserat på ett nytt data material bestående av observationer på 16 variabler i 232 val i Afrika, görs tre olika analyser. Först avvisas ett antal etablerade hypoteser om nutida Afrikansk politik och demokratisering. Sedan påvisas valens självförstärkande och självförbättrande kraft med hänvisning till institutioners interna logik och strukturering av aktörers incitamenThis book is about elections and democracy in newly democratizing countries. Building on a new data set of 5,568 observations in 232 elections, it provides evidence elections have a casual impact on improving the quality of democracy in Africa in more than one way. The study demonstrates multiparty elections do not signal the end of transitions to democracy but rather foster liberalization and hav

Optical properties, durability, and system aspects of a new aluminium-polymer-laminated steel reflector for solar concentrators

A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test

Amplification of 12q13 and 12q15 sequences in a sclerosing epithelioid fibrosarcoma

Sclerosing epithelioid fibrosarcoma (SEF) is a recently described entity. It is a low-grade sarcoma that occurs primarily in the deep soft tissues of the extremities of adults. It may histologically simulate benign lesions such as fibroma and myxoma or malignancies such as sclerosing carcinoma and lymphoma, extraskeletal myxoid chondrosarcoma, clear cell sarcoma of tendons and aponeuroses, and syn

A comparison of the Gauss-Newton and quasi-Newton methods in resistivity imaging inversion

The smoothness-constrained least-squares method is widely used for two-dimensional (2D) and three-dimensional (3D) inversion of apparent resistivity data sets. The Gauss-Newton method that recalculates the Jacobian matrix of partial derivatives for all iterations is commonly used to solve the least-squares equation. The quasi-Newton method has also been used to reduce the computer time. In this me

The effects of a pesticide mixture on aquatic ecosystems differing in trophic status: responses of the macrophyte Myriophyllum spicatum and the periphytic algal community

The effects of a pesticide mixture (asulam, fluazinam, lambda-cyhalothrin, and metamitron) on aquatic ecosystems were investigated in 20 outdoor aquatic microcosms. Ten of the microcosms simulated mesotrophic aquatic ecosystems dominated by submerged macrophytes (Elodea). The others simulated eutrophic ecosystems with a high Lemna surface coverage (Lemna). This paper describes the fate of the chem

The Bhagavadgītā Path of Yoga

On the basis of text-internal evidence, the article supports the view that the soteriological doctrines of the Bhagavadgītā comprise a structured and progressive system in which partially conflicting elements derived from contemporary religious teachings have been deliberately arranged in hierarchical form, and touches on philological problems in connection with particular passages.
