In 1524, Petrus Apianus published two closely related works—one the Latin Cosmographicus liber, aimed at an educated audience of international readers, and the other, Ein kunstlich Instrument, a shorter, more practical book for those who could read German but had no Latin. Both books nevertheless make use of most of the same instruments, including Apianus’ early volvelles. Most of these instrument

We prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions. As a corollary, we obtain a relatively complete classification of solitary waves: they must be sup

Artikeln undersöker hur praktisk kunskap framställs i bild. En rad tidskrifter inom konsthantverks, hemslöjds- och konstområdet har undersökts. Resultatet pekar på hur viktig just din hand är för att förmedla kopplingen mellan dig som gör och det du gör.

Benchmarking har blivit en allt vanligare metod för lärosätens kvalitetsarbete. Lunds universitet har deltagit i benchmarkingprojekt organiserade av European Centre for Strategic Management of Universities (ESMU) sedan 2000. Sedan några år tillbaka medverkar Lunds universitet återigen i ett antal internationella projekt rörande benchmarking av e-lärande, nämligen EADTU:s E-xcellence+, ESMU:s eLear

Popular Abstract in Swedish I atmosfären finns mikroskopiskt små luftburna partiklar. Till skillnad från makroskopiska partiklar sedimenterar dessa så kallade ’aerosol-partiklar’ så sakta att de följer med den omgivande luftens rörelser. I atmosfärens nedre luftlager (troposfären) avlägsnas aerosolpartiklarna från atmosfären av nederbörd. Partiklarna deponerar därför inom någon vecka. Ovanför tropThis thesis focuses on the influence of volcanism on the compositions of the aerosols in the upper troposphere (UT) and lowermost stratosphere (LMS), and their direct and indirect impact on climate. Aerosol data were obtained by aircraft-borne sampling, using the CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) platform, and laboratory-based

An agonistic approach to ethnography illuminates the complexities of researching in Palestine, where violent Israeli border regimes create pro- found socio-political divides. This framework highlights the methodological challenges and the transformative potential of ethnographic inquiry in contentious environments.

A recent body of empirical studies has given us a reason to expect that an influx of low-skilled workers can increase high skilled female market labour supply. Most of these studies, however, have focused on developed countries and on investigating the impact as it pertains to immigration. Believing that this same effect might hold in the case of internal migration, in this study, I employ a shift-s
