Document about the proposed establishment of a center for German Jewish culture and genealogy in Berlin or HamburgdigitizedThe manuscript has been removed from the ‘Lehranstalt fuer die Wissenschaft des Judentums Collection’, AR 11844Born in Hamburg on February 26, 1896, Erna Magnus was a social worker who was engaged in an historical study of the Jewish community of Hamburg during the 1930s. She emigrated to the United States in 1939, where she held various social work and teaching position

Comparing consortial repositories: a model-driven analysis
This study aims to provide a comparative assessment of different repository consortia as a reference to inform future work in the area. A review of the literature was used to identify repository consortia, and their features were compared. Three models of consortial repositories were derived from this comparison, based on their structure and aims. The consortial models were based around either: creating a shared repository for the members, developing a repository software platform or creating a metadata harvesting service to aggregate content. Using case studies of each type of repository consortium, each model was assessed in terms of its particular strengths and weaknesses. These strengths were then compared across the models to enable those considering a consortial repository project to assess which model, or combination of models, would best address their needs and to aid in project planning

Training for Entrepreneurship and New Businesses
An important part of governmental industrial policy is to support entrepreneurship and the creation of new businesses through various programmes. These are often organized at regional or local level by support organizations such as innovation centres (at universities), regional development funds and science parks. Earlier studies of business support structures have focused mainly on the ‘demand’ side; that is, on participants' perceptions of the usefulness of taking part in different support programmes. These studies have shown that there is a mismatch between the supply and demand side in business support activities. This paper deals with the supply side's view of organizing support activities for entrepreneurs and new businesses. The author analyses the responses to a questionnaire survey of business support organizations in Sweden. The results show that the support organizations are well aware of the problems the participants have – relating to, among other things, time, educational methods, finance, priorities, and access to information. At the same time, the support organizations disagree with suggestions that they are too theoretical in their teaching, lack experience in the problems of small businesses, offer inflexible programmes, have problems communicating, or lack teaching expertise (in, for example, training programmes). This paper discusses the gap in perception between the suppliers and their market and addresses the policy issues it raises. The implications for training for entrepreneurship and new businesses are also addressed. </jats:p
Direct electron transfer based biofuel cells : operating in vitro and in vivo
I vår moderna värd är vi väldigt beroende av elektrisk energi som vi använder för det mesta i får vardag: för att lysa upp våra hus, generera värme, driva våra datorer och mobiltelefoner och mycket mer. Produktion av elektrisk energi har dock ofta en negativ på-verkan på vår miljö. Ett alternativt sätt att producera elektrik energi är att använda sig av bränsleceller, vilka kan liknas vid öppna batterier som ständigt kan förses med nytt bränsle och således inte behöver bytas ut efter ett tag. Bränslet som används kan väljas så att dess förbrukning inte innebär någon negativ påverkan på miljön.
Den här avhandlingen fokuserar sig på en viss typ av bränsleceller, där
man använder sig av specifika proteiner, enzymer, för att omvandla energi
från bränslet till elektrisk energi. Som bränsle kan vanligt förekommande kolhydrater,
dvs. socker, samt syre användas. Socker och syre används även av vår
kropp för att skapa energi, och genom att använda sig av rätt sorts enzymer
kan även bränsleceller använda sig av dessa ämnen för att producera elektrisk
energi. Således är det möjligt för dessa bränsleceller att producera elektrisk
energi placerade inuti oss. Dessa biobränsleceller kan sedan användas för att
driva t.ex. olika sensorer direkt i vår kropp som kontinuerligt skulle kunna
ge information till sjukvården, utan att använda sig av batterier som behöver
bytas ut. Avhandlingen är baserad på att undersöka hur olika bränsleceller
som använder sig av enzym fungerar samt att testa dem i olika mänskliga
kroppsvätskor samt även inuti levande organismer. Genom att öka förståelsen
för detta är förhoppningen att bränsleceller baserade på enzym inom en inte allt
för avlägsen framtid kan finna tillämpningar som elektriska försörjare för t.ex.
självförsörjande biomedicinska sensorer.The focus of this thesis is the development and design of direct electron transfer based enzymatic fuel cells, with the possible use in biomedical applications. For biodevice fabrication, macro- and micro-scaled nanostructured gold electrodes were fabricated and characterized in detail, employing electrochemical techniques, as well as atomic force microscopy and scanning electron microscopy. The nanostructured electrodes were utilized together with suitable (bio)catalysts to achieve efficient catalysis of suitable biofuel and biooxidant.
Oxygen was utilized as biooxidant, employing the enzyme bilirubin oxidase together with nanostructured electrodes to achieve efficient bioelectrocatalysis. The mechanism of bioelectrocatalytic reduction of oxygen by bilirubin oxidase was investigated in detail utilizing electrochemical techniques combined with quantum mechanic/molecular mechanic modeling.
Carbohydrates were utilized as the main biofuel in most of the studies, by employing cellobiose dehydrogenase immobilized on nanostructured electrodes. Additionally, tetracyanoquinodimethane and tetrathiafulvalene were employed as efficient catalysts of ascorbate.
The performance of assembled enzymatic fuel cells were in-vestigated in vitro in complex buffers and human physiological fluids, as well as in vivo evaluated using different electrochemical techniques

Numerical Simulation of Negative Magnus Force on a Rotating Sphere
Flow characteristics and fluid force on a sphere rotating along with axis perpendicular to mean air flow were investigated using Large Eddy Simulation (LES) at two different Reynolds numbers Re_[p] of 1.0×10^[4] and 2.0×10^[5]. As a result of simulation, opposite flow characteristics around the sphere and displacement of the separation point were visualized depending on the Reynolds number even though rotation speed according to the Reynolds number is the same. When the sphere rotates at some specific rotation velocity and at Re_[p] = 1.0×10^[4], flow characteristics agree with the flow field explained in the Magnus effect. While sphere rotates at the same rotation velocity while increasing Re_[p] to 2.0×10^[5], separation point moves in opposite direction and wake appears in the different direction. The reason of the negative Magnus force was discussed in terms of the boundary layer transition on the surface
