Prevailing winds carry seafarers across oceans and guide insects on their journeys. The South African, ball-rolling dung beetle Kheper lamarcki depends on a range of compass cues, including the azimuthal position of the sun and the directed airflow of wind to steer its plotted course. In this thesis, I set out to further our understanding for how these insects benefit from the directional componen
In this study, a novel macroporous composite biomaterial consisting of gelatin-hydroxyapatite-calcium sulphate for delivery of bone morphogenic protein-2 (rhBMP-2) and zoledronic acid (ZA) has been developed. The biomaterial scaffold has a porous structure and functionalization of the scaffold with rhBMP-2 induces osteogenic differentiation of MC3T3-e1 cells seen by a significant increase in bioch
This article focuses on how the European Union's (EU) mediation activities during the Russia-Ukraine and Israel-Palestine conflicts are perceived by local elites. Our analysis is based on recent interviews with decision makers in Ukraine, Israel and Palestine. Consistent with this special issue, we investigate perceptions of EU roles, strategies and effectiveness. We suggest that the EU's relation
Metabolic rate reflects the ‘pace of life’ in every organism. Metabolic rate is related to an organism’s capacity for essential maintenance, growth and reproduction-all of which interact to affect fitness. Although thousands of measurements of metabolic rate have been made, the microevolutionary forces that shape metabolic rate remain poorly resolved. The relationship between metabolic rate and co
From early childhood, Hanna, born with Spinal Muscular Atrophy II, has adhered to a standing posture for all her independent locomotion. Aim: To investigate why Hanna in childhood chose to stand and the meaning that standing holds for Hanna as an adult. Method: Single case study of a single person, Hanna, based on her contemporary statements as an adult about her lived experience from childhood, i
X-ray examinations of the pelvis and the urinary tract are frequent examinations of children, in which a large part of the trunk is irradiated. The irradiated volume contains many of the most radiation sensitive organs and tissues. The absorbed dose to children during the examination was estimated from measurements with a dose-area product meter and thermoluminescent dosemeters (TLDs). Entrance su
The question of Jewish ancestry has been the subject of controversy for over two centuries and has yet to be resolved. The "Rhineland hypothesis" depicts Eastern European Jews as a "population isolate" that emerged from a small group of German Jews who migrated eastward and expanded rapidly. Alternatively, the "Khazarian hypothesis" suggests that Eastern European Jews descended from the Khazars, a
Massive multiple-input multiple-output (MIMO) arrays are becoming critical elements in cellular base station infrastructure. We utilize the theory of characteristic modes (TCM) to design a novel tri-modal broadside antenna element which is suitable for the construction of compact massive MIMOarrays. The proposed antenna element consists of three ports which is formed by reviewing an existing compa
Forskare har ett särskilt ansvar i klimatfrågan, menar Emma Kritzberg vid Lunds universitet. Hon är en av dem som verkat för vegetariskt som standardval vid biologiska institutionen.
A high-resolution study of the (e,e'p) reaction on Helium-4 was carried out at the Institut fuer Kernphysik in Mainz, Germany. The measurements were done in parallel kinematics (momentum transfer q=685 MeV/c, energy transfer omega=334 MeV) at different incident beam energies in order to enable the Rosenbluth separation of the longitudinal and transverse response functions.
The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack-ice zone. Salomonsen (1967, Biologiske Meddelelser, Copenhagen Danske Videnskabernes Selskab, 24, 1) put forward a hypothetical comprehensive interpretation of this global migratio
This article examines the changing role of the Swedish state in employmentand welfare regulation in an environment that has become more market driven,commodified, and Europeanized. It begins with a theoretical reflection on the role of the state in capitalist development and a review of the recent debate on the spatiality of state regulation: the state as employer, redistributor, and arbiter, and
Purpose – Evasive entrepreneurs innovate by circumventing or disrupting existing formal institutional frameworks. Since such evasions rarely go unnoticed, they usually lead to responses from lawmakers and regulators. The paper aims to discuss this issue. Design/methodology/approach – The authors introduce a conceptual model to illustrate and map the interdependencey between evasive entrepreneurshi
This study examines the rise and fall of the modern Belarusian national movement during the quarter century between 1906, the year when the first Belarusian paper appeared, until its demise around 1931, as a result of political repression in the Soviet Union and Poland. It surveys the emergence of the modern concept of a Belarusian nation, from the first steps towards national consolidation in the
A 1561-year tree-ring width (TRW) chronology covering the period 2668–1108 BC (4617–3057 BP) has been developed from 159 moisture-sensitive peatland pines (Pinus sylvestris L.) sampled at Åbuamossen, southern Sweden. Tree population dynamics and annual growth responses of the trees were shown to reflect and give absolute age to regional hydro-climatological changes. The main wet-shifts recorded in
