The amphorae from Kops Plateau represent a singular example of Roman military supply in northern Europe at a very early date. Their analysis sheds light on trading routes in the Atlantic regions, and from Gaul to Germany.

Book Description
A steadfast misbelief in precision bombing evolved into the leading concept for US Army Air Force during the Second World War. This concept envisioned the destruction of the German industrial and economic system as the swiftest path to victory. However, the belief in survivability of bombers through self defense proved incorrect, and the Allies realized that the Luftwaffe had to be defeated first, by attacking the German aircraft industry. On 22 February 1944, Eighth Air Force conducted a mission as part of this offensive. During this mission, the bombers were recalled because of severe weather. On the return trip, the airmen decided not to abandon the mission outright, but to attack targets of opportunity. Because of navigational errors a section of 446 Bombardment Group misidentified the Dutch city Nijmegen as in Germany, and bombed it. Due to aiming errors, the greater part of the bombs missed the designated marshalling yards by a kilometer, and hit the city center instead. The bombardment caused chaos on the ground. It surprised the citizens, ignorant by earlier faulty alarms, and damage caused great difficulties for the provision of aid relief. As a result, the bombardment killed about 800 citizens and destroyed the historic city center.

AUGUST F. DEUTMAN, M.D. From October 16-18, 197 5 many distinguished ophthalmologists visited Nijmegen to inaugurate the new Eye Institute of the University of Nijmegen with a symposium on New Developments in Ophthalmology. The meeting was held under the auspices of the Netherlandish Ophthalmological Society (NOG) and had a high attendance of over 300 ophthalmologists from The Netherlands and from abroad. Many new and some controversial surgical techniques regarding corneal transplantation, phako-emulsification, intra-ocular lensimplantation, local excision of melanomas of the choroid and ciliary body, pars plana vitrec tomy, laser treatment in disciform macular degeneration and treatment of giant retinal tears were discussed. Since new surgical techniques have to be based on profound knowledge of the anatomy and physiology of the eye, many new basic and important data regarding the cornea, the vitreous body, the retinal vessels, the choroid and the orbit were presented by some of the foremost authorities. Technical advances in corneal transplantation were discussed, while the modern treatment of corneal ulcers and bacterial infections of the eye was presented. New findings such as computerized tomography, facilitate the diagnosis of underlying disease in exophthalmus enormously. The treatment of retinal detachment has improved considerably over the last ten years and we feel that in particular the safe non-drainage methods deserve attention. Cryo coagulation and photocoagulation have certain advances over diathermy and the radial placement of indenting suprascleral material may have consider able advantages over the limbus-parallel placement in horseshoe tears.

Book Description
This WWII biography chronicles an American paratrooper’s harrowing role in Operation Market Garden and his heroic survival as a POW. During World War II, Gene Metcalfe served in the 82nd Airborne. After his recruitment into the military at Camp Grant, he trained with the 501st Paratroop Infantry Regiment at Camp Toccoa. It wasn’t until D-Day that he first arrived in England to join the 508th PIR. On September 17th, 1944, the 508th PIR embarked on Operation Market Garden to establish a salient in the Netherlands. Flying over Groesbeek Heights, just outside of Nijmegen, Holland, Metcalfe was among the first to jump into what swas thought to be an empty meadow. Instead, it was defended by German antiaircraft cannons. As he jumped into a hail of bullets he watched his plane roll over and plummet into the ground. Badly injured by a shell explosion, Gene was listed as Killed In Action and left for dead by his patrol. He became a POW held outside Munich, moved between various dieses-ridden camps. After a nearly successful escape attempt—he was captured within sight of the Swiss mountains—Gene was liberated by American troops in 1945.

Book Description
In these times where connectionist accounts of brain function are gaining in popularity, there is a need for reliable tools for determining anatomical connectivity in the living human brain. The technique of choice is diffusion MRI, but it is debatable whether this tool is suitable for mapping all but the major pathways. The thesis describes my contribution to the development and validation of tools to map the connections in the human brain. To honour the giants whose shoulders we stand on, and to provide neuroanatomical background, the thesis starts with a historical essay on connectional neuroanatomy. MRI techniques are introduced, focusing on the two modalities most relevant to the topic: diffusion MRI and susceptibility MRI. The thesis starts with proposing a novel tractography method: Structure Tensor Informed Fibre Tractography (STIFT). With STIFT, the strengths of diffusion MRI (angular resolution) and susceptibility MRI (spatial resolution) are harnessed in one technique. It provides improved spatial specificity of the resulting tracts. Furthermore, in regions with complex fibre configurations, STIFT is able to distinguish between crossing and kissing fibres. Although the method might not be applicable to all tracts in the brain, STIFT is expected to be a useful addition to the tractographer’s toolkit. The focus then shifts to the cortex. Cortical diffusion imaging becomes increasingly relevant now that high resolutions can be achieved in vivo, which perhaps allows fibres to be tracked into the cortex. By imaging human tissue samples of the primary visual cortex ex vivo on preclinical MR systems, it was demonstrated that cortical diffusion properties are layer-specific. While infra- and supragranular layers show anisotropic diffusion tensors oriented radially to the cortical sheet, the stria of Gennari has low anisotropy. Additionally, the thesis has shown that cortical layers could be better distinguished with the biophysical model NODDI than with conventional diffusion models. In that investigation, diffusion MRI and histology both suggested that fibre dispersion patterns at the grey-white matter boundary vary over the folding cortical sheet. The gyral fibre configurations were investigated further by high resolution diffusion tensor imaging at 7T in vivo. A characteristic pattern of fibre anatomy of the gyrus was derived, in which we observed variations of tensor anisotropy and radiality with cortical curvature, not only in the white matter, but also within the cortex. This set of experiments has considerable implications for tractography, suggesting that (artefactual) biases towards particular locations on the cortical sheet might exist; that models should be designed to capture a variety of dispersion and crossing patterns for tracking fibres in the gyrus; and that intracortical tractography might one day be feasible. The neuroanatomical teaching tools that are described in the final part of the thesis were created by combining white matter dissection, plastination and tractography. The plastinated prosections have considerable advantages over formalin-fixed specimens because they are durable, non-toxic and easy to handle. These tools might inspire new generations of students to take up research in connectional neuroanatomy.
