Ausspracheübungen in finnischen DaF-Lehrwerken : eine Untersuchung an sechs Lehrwerkserien für die Anfängerstufe
2007
Zu interkulturellen Begegnungen in der gymnasialen Oberstufe : Erfahrungen finnischer Schüler mit finnisch-deutschen Schulpartnerschaften
2011
Nykyinen käsitys vieraiden kielten opettamisesta Suomessa painottaa kielen lisäksi myös kohdekulttuurin tuntemusta. Kielen opetuksessa tulisi huomioida sen kulttuurinen konteksti. Tämän tutkimuksen tavoitteena oli kartoittaa suomalaisten lukiolaisten kokemuksia ulkomaisesta ystävyyskoulutoiminnasta. Erityisen kiinnostuksen kohteena olivat lukiolaisten motiivit osallistua projektiin, heidän näkemyksensä projektin suunnittelusta ja toteutuksesta, sekä heidän kokemuksensa projektin vaikutuksista kulttuurienväliseen oppimiseen ja kielitaitoon. Työn teoreettisessa osassa tarkastellaan kulttuurienvälistä kompetenssia kansainvälisyyskasvatuksen tavoitteena Suomen lukio-opetussuunnitelmassa ja sen …
A new automated single ring infiltrometer for Beerkan infiltration experiments
2014
A new automated compact device was developed to collect data from single ring infiltration experiment. The infiltrometer consists of a containment ring in which a small quasi-constant head of water (i.e. a few mm) is maintained by a Mariotte reservoir and a very inexpensive data acquisition system, based on the open source microcontroller platform Arduino, and a differential pressure transducer. The design can easily be reproduced and operated. The infiltrometer was tested in a citrus orchard on a sandy loam soil. A simple methodology was applied for an accurate data acquisition from the initial stage of the process and to minimize the disturbance of the soil surface. A new approach to proc…
Exploring Azure Active Directory Attack Surface: Enumerating Authentication Methods with Open-Source Intelligence Tools
2022
Azure Active Directory (Azure AD) is Microsoft’s identity and access management service used globally by 90 per cent of Fortune 500 companies and many other organisations. Recent attacks by nation-state adversaries have targeted these organisations by exploiting known attack vectors. In this paper, open-source intelligence (OSINT) is gathered from organisations using Azure AD to explore the current attack surface. OSINT is collected from Fortune 500 companies and top 2000 universities globally. The collected OSINT includes authentication methods used by the organisation and the full name and phone number of the primary technical contact. The findings reveal that most organisations are using…
Testing a Simplified Approach to Determine Field Saturated Soil Hydraulic Conductivity
2013
Abstract Interpreting and simulating hydrological processes need a large number of field saturated soil hydraulic conductivity, Kfs , data that should be collected with simple and rapid field experiments. A Simplified method based on a Beerkan Infiltration run (SBI method) was recently developed and tested successfully on Burundian soils. With the SBI method, a cylinder is inserted to a short depth into the soil and the infiltration time of a few small volumes of water repeatedly applied at the surface of the confined soil is measured. Calculating Kfs needs the slope of the linearized cumulative infiltration vs. time relationship and an estimate of the so called α* parameter. In this invest…
Adaptive discontinuous evolution Galerkin method for dry atmospheric flow
2014
We present a new adaptive genuinely multidimensional method within the framework of the discontinuous Galerkin method. The discontinuous evolution Galerkin (DEG) method couples a discontinuous Galerkin formulation with approximate evolution operators. The latter are constructed using the bicharacteristics of multidimensional hyperbolic systems, such that all of the infinitely many directions of wave propagation are considered explicitly. In order to take into account multiscale phenomena that typically appear in atmospheric flows nonlinear fluxes are split into a linear part governing the acoustic and gravitational waves and a nonlinear part that models advection. Time integration is realiz…
Le Istituzioni di Gaio e il Glücksstern di Niebuhr
2012
Sulla base della documentazione manoscritta, anche inedita, e di altre fonti si ripercorrono le vicende che portarono nel 1816 Barthold Georg Niebuhr a scoprire il palinsesto delle Istituzioni di Gaio nella Biblioteca Capitolare di Verona e si discute criticamente la casualità di tale scoperta.
Mitochondrial DNA Regionalism and Historical Demography in the Extant Populations of Chirocephalus kerkyrensis (Branchiopoda: Anostraca)
2012
BackgroundMediterranean temporary water bodies are important reservoirs of biodiversity and host a unique assemblage of diapausing aquatic invertebrates. These environments are currently vanishing because of increasing human pressure. Chirocephalus kerkyrensis is a fairy shrimp typical of temporary water bodies in Mediterranean plain forests and has undergone a substantial decline in number of populations in recent years due to habitat loss. We assessed patterns of genetic connectivity and phylogeographic history in the seven extant populations of the species from Albania, Corfu Is. (Greece), Southern and Central Italy.Methodology/principal findingsWe analyzed sequence variation at two mito…
