Graduation project A transformation of a former railway area in Haarlem into a Museumpark. A transformation of the Seinwezen building which is the main building in the plot. Two building have been added to the Seinwezen based on the essence, which is the shape. Interior walls have been removed to open it up. Through the three buildings runs a railway track.RMITArchitectur

Two-legged body
The invention relates to a two-legged body comprising at least two legs, an oscillation element and a connecting element for the mutual coupling of the legs and the oscillation element, wherein the legs are pivotable in relation to the connecting element and during operation undergo a reciprocating angular displacement in relation to the connecting element, depending on the oscillation element. The oscillation element comprises at least two springs for the generation of antagonistic forces, which springs each are coupled at one side with a leg, and together with the mass present in the body they are able to form a vibrating mass-spring system. The spring stiffness of at least one spring is adjustable.Mechanical, Maritime and Materials Engineerin
Hilo harbor tsunami model - reflected waves superimposed
The city and harbor of Hilo, located on the northeast coast of the island of Hawaii, have been severely damaged by numerous tsunamis. Physical features which play an important role in the formation of tsunami bores at Hilo are the submarine ridge formations in deep water outside the bay mouth and the nearly vertical cliffs along the Hamalcua coast which reflect the tsunami wave into the harbor. The purpose of this paper is to discuss the Hilo Harbor Tsunami Model and this reflected wave and its effects. The tests described and the resultant information presented herein, unless otherwise noted, were obtained from research conducted under the Hilo Harbor Model Study of the United States Army Corps of Engineers by the Honolulu Engineer District.

Knowledge of the genomic and taxonomic diversity of Acidithiobacillia is still limited. Here, we present a systematic analysis of nearly 100 genomes from the class sampled from a wide range of habitats. Some of these genomes are new and others have been reclassified on the basis of advanced genomic analysis, thus defining 19 Acidithiobacillia lineages ranking at different taxonomic levels. This work provides the most comprehensive classification and pangenomic analysis of this deep-branching class of Proteobacteria to date. The phylogenomic framework obtained illuminates not only the evolutionary past of this lineage, but also the molecular evolution of relevant aerobic respiratory proteins, namely the cytochrome bo3 ubiquinol oxidases

Publisher Copyright: © 2020, The Author(s).Strain MG, isolated from an acidic pond sediment on the island of Milos (Greece), is proposed as a novel species of ferrous iron- and sulfur-oxidizing Acidithiobacillus. Currently, four of the eight validated species of this genus oxidize ferrous iron, and strain MG shares many key characteristics with these four, including the capacities for catalyzing the oxidative dissolution of pyrite and for anaerobic growth via ferric iron respiration. Strain MG also grows aerobically on hydrogen and anaerobically on hydrogen coupled to ferric iron reduction. While the 16S rRNA genes of the iron-oxidizing Acidi-thiobacillus species (and strain MG) are located in a distinct phylogenetic clade and are closely related (98–99% 16S rRNA gene identity), genomic relatedness indexes (ANI/dDDH) revealed strong genomic divergence between strain MG and all sequenced type strains of the taxon, and placed MG as the first cultured representative of an ancestral phylotype of iron oxidizing acidithiobacilli. Strain MG is proposed as a novel species, Acidithiobacillus ferrianus sp. nov. The type strain is MGT (= DSM 107098T = JCM 33084T). Similar strains have been found as isolates or indicated by cloned 16S rRNA genes from several mineral sulfide mine sites
Analyzing the Combined Role of Good Governance and GDP on Women Literacy in African Countries
Most African countries have been affected due to economic crises regarding hyperinflation and lower agricultural productivity, civil war, lower infrastructural and transportation systems, social and domestic violence, food insecurity due to bad agricultural systems, social and religious inequality, mismanagement of governing systems with defective bureaucracy, environmental degradation and lower practice for sustainable development. In this paper, the author tries to find out two research objectives i) To measure the good governing variables on women literacy between East and West African countries ii) To measure the joint impact of good governance and GDP level between these two countries. The author uses secondary dataset from The World Bank site on quantitative analysis where the author uses multiple regression model for general regression and integrated regression model. At the time of multiple regression (Model 1), GDP, IF, P.S., R.Q. has a positive connection with women literacy for EAC. On the contrary, PHR, FLF, DOFC, R.L. create a negative effect on women's literacy in EAC. But in (Model 2), if the good governance variable connects with GDP for long-lasting development, (GDP*PS), (GDP*RQ) has positive connection with W.L. in EAC. Reversely, L.E., PHR, G.E., R.Q., CC has positive and significant impact in WAC where these variables enhance women literacy to be improved at significant rate (Model 3) where DOFC and EFC has reverse connection with W.L. In spite of case, if GDP connects with good governance variables, (GDP*RQ) and (GDP*PS) has positive connectivi-ty with W.L. in WAC. Policy makers should highlight to promote effective R.L. and G.E. to improve macroeconomic development in EAC where governments of WAC should focus on R.L. and G.E. to ensure women empowerment and social security for sustainable development. Establishing good governance's variables in African countries is carrying need to ensure women empowerment, lessening gender inequality, ensuring women safeness and sustainable development etc
The Influence of Teleoperator Stiffness and Damping on Object Discrimination
Human task performance using teleoperator systems depends on the physical and controlled parameters of the system. Two teleoperated grasping tasks—size and stiffness discrimination—were studied to investigate how changes in system parameters influence human capabilities. The device characteristics altered were teleoperator stiffness (size and stiffness discrimination) and teleoperator damping (size discrimination only). It was found that neither teleoperator stiffness nor teleoperator damping influenced size discrimination. Also, teleoperator stiffness did not influence stiffness discrimination. Furthermore, teleoperated performance was compared with direct interaction using bare hands or with the fingers in a bracket. Size discrimination performance was equivalent for these three conditions, but stiffness discrimination performance was lower for teleoperation than for direct interaction.Precision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin

Rent Collection, Rent Distribution, and Cost Recovery: An Analysis of Iceland’s ITQ Catch Fee Experiment
Resource rentals can be defined as payments made by the user of a resource to the stakeholders to whom the payment accrues. Typically, resource rentals take the form of a payment by a commercial enterprise to the state. Resource rentals can be viewed as a tax on resource rents (i.e., on net income derived from the use of a resource) or as royalties or access fees to a resource. The Icelandic Fishery Management Act requires that vessel owners pay a resource rental in the form of the “catch fee†(veidigjald), which is one of the first attempts to explicitly use resource rent generated in fisheries as a base for government revenue. This paper first discusses the legislative activity leading up to the introduction of the catch fee, followed by a discussion of how the Fishery Management Act defines the fee. Then, the effect of using a quota-lease-charge rule is discussed and finally there is an evaluation of whether the catch fee is high enough.Resource rentals, catch fee, ITQs, Icelandic fishery management, Environmental Economics and Policy, Institutional and Behavioral Economics, International Relations/Trade, D33, D63, H21, Q22, Q28,
