The selection of design loads and requirements is defining the structural weight of airplanes and their safety. Therefore the definition of requirements should be performed very critically by the customer and structural weight should be assessed based on sensitivity analysis of the total aircraft which includes flight manoeuvre simulation, flight control system, aerodynamics and elastic effects introduced by finite elements. To produce these analyses is the job of the aircraft companies. After selection of most load critical flight manoeuvres (pull up manoeuvres, initiation of roll manoeuvres etc.) the calculation of airloads and inertia loads must include the flight control system and its failure cases because it affects the motion of the control surfaces and therefore the aircraft. With the advent of carbon fibre composite structures discrete loads are the predominant limiting design conditions but it should be emphasised that most structures are of a hybrid nature with metal frame which are still susceptible to fatigue loads. For airplanes designed to civil requirements such as transport airplanes, tankers etc. the definition of continuous turbulence and inclusion of FCS failure cases and nonlinearities such as control surface angles is extremely important. There was a long way from load assumptions used by the Wright Brothers who designed their Flyer to a 5g limit to the load limiting capabilities of the care free handling flight control system of the Eurofighter. Also the US-Airforce Mil-Specifications which were used to design NATO airplanes such as Tornado, F16 and F18 in the 1970’s are obsolete today and the MIL-A-87221 (USAF) is only a frame without the essential quantitative material. All these issues are addressed in this manual including comparisons of regulations and descriptions of new specifications. Complete procedures how to establish design loads are presented which should help for the design of new airplanes. The importance of dynamic phenomena which produce design loads for various aircraft parts such as intakes, leading edges etc. is also highlighted. Loads monitoring systems are necessary to prove calculated loads and monitor fatigue loads to establish the remaining structural life. There is a description of a modern system. For transport type aircraft gust load cases are the most critical for strength design and they are also the main fatigue loading source for the major part of the structure. Methods for discrete and continuous gust loading cases are presented together with nonlinear example calculations. In the appendix there is a description of failure cases and their effect on loads for transport aircraft and a specification of a landing gear which could be used as an example how to specify the whole structure as a system. The military use of this manual is to establish procedures to build the lightest structure for the military requirements. Agreement on requirements and design loads within the NATO countries could standardise pilot training, aircraft usage, increase aircraft life and reduce maintenance. Since the search of the best usage of the aircraft for its military purpose will continue to integrate structure and avionics such as fire and flight control systems as an example there will be a continuous need for future work.

BACKGROUND: Addition of glutamine to enteral nutrition formulas is consistently associated with a significant decrease in septic morbidity in critically ill patients, possibly related to the attenuation of gut dysfunction. This pilot study was undertaken to compare the effects of enteral administration of two glutamine-enriched formulas containing either additional free glutamine or glutamine-rich proteins, with a standard solution on plasma and mucosal concentrations of glutamine in patients admitted in the Department of Intensive Care. METHODS: Following randomization, glutamine concentration was determined in endoscopically sampled duodenal biopsies and plasma, before and after a 7-day period of continuous administration of the designated solution. RESULTS: The mucosal concentration of glutamine increased in the duodenal biopsies sampled from patients randomized to the solution containing the glutamine-rich proteins (from 3.6 +/- 2.2 to 6.7 +/- 5.2 micro-mol/g protein), but not from the others. There were no differences between the 3 groups in the plasma concentrations of glutamine, which remained stable over time. CONCLUSION: The source of supplemental glutamine can influence gut mucosal glutamine concentrations, suggesting differences in its availability or utilization. [less ▲]

It was demonstrated in 1981 that chronic GVHD was associated with a strong decrease of the relapse risk after conventional allogeneic hematopoietic cell transplantation (graf-versus-tumor effects). Recent studies suggest that chronic GVHD might also been associated with improved progression-gree survival after allogeneic hematopoietic cell transplantation with reduced-intensity conditioning (RIC-allo), a transplant strategy based mainly on graft-versus-tumor effects for tumor eradication. Further, it has been demonstrated that elimination of leukemic cells after RIC-allo is due to donor T-cell cloones directed against multiple minor histocompatibility antigens (specific for the recipient) that are largely expressed not only by tumor cells but also by non-hematopoietic tissues, explaining the strong association between GVHD and graft-versus-tumor effects seen after RIC-allo.

Background: The Ehlers-Danlos syndrome (EDS) represents a heterogenous group of heritable connective tissue disorders chiefly characterized by joint laxity, increased skin distensibility and connective tissue fragility. Each EDS type corresponds to a multisystemic disorder with widespread implications. Physicians evoke the EDS diagnosis in presence of some typical cutaneous signs, such as atrophic scars and frequent hematomas. Methods: To revisit the transmission electron microscopy support from skin biopsies when screening EDS in gynecology-obstetrics. Results: EDS women commonly suffer from a series of gynecologic and obstetric disorders. Dermal ultrastructural changes are keynote features suggesting some EDS types. Conclusion: Gene mutations are mostly identified in the classic and vascular EDS types, but only in sporadic cases of the hypermobile EDS type which apparently represents the most frequent type. Dermal ultrastructural changes represent relevant diagnostic clues for the practitioner. Preconception counseling about possible complications is welcome. Management requires precise diagnosis of the EDS type. [less ▲]

In the present study, we used meiotic gynogenesis, widely used in studies on sex determination, to confirm female homogamety in Eurasian perch, Perca fluviatilis. Sperm irradiated with UV for 400 s was used to artificially fertilized eggs. The diploid of the resulting embryos was restored by a heat shock (30 degreesC) applied to the eggs 5 min postfertilization, for 25 min. Fertilization (ranging between 45% and 75%) and survival rates at hatching (ranging between 3.4% and 46.6%) were not significantly different (P>0.05) between the diploid control and gynogenetics. The diploid controls and two batches of gynogenetics contained 100% diploid larvae, whereas two other batches of gynogenetics contained 6.7% and 10.0% triploid larvae. The sex ratios of the diploid controls were not significantly different from 1:1, whereas all gynogenetic families were 100% female. These results confirm female homogamety in Eurasian perch, demonstrated by the use of hormonally mascilinized breeders in a previous study. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

The histaminergic system has been speculated to be involved in the inhibitory control of drug reward, H-1 and H-2 antagonists having been found to potentiate conditioned place preference induced by morphine or cocaine. In contrast, the role of H-3 receptors in cocaine-induced place preference is still unknown. The present study tested the effects of thioperamide (0, 10 and 20 mg/kg, i.p.), an H-3 autoreceptor antagonist, on the development of a conditioned place preference induced by cocaine (0, 2 and 8 mg/kg, i.p.) in C57BL/6J mice. Thioperamide was injected 10 min before each cocaine-pairing session. The activity scores recorded on the first cocaine-pairing session were also used to test the effects of thioperamide on cocaine-induced locomotor activity. Thioperamide alone had no reinforcing effects and did not affect the conditioned place preference induced by 8 mg/kg cocaine. However, thioperamide dose-dependently revealed a conditioned place preference induced by 2 mg/kg cocaine, a dose that was inactive per se. Finally, thioperamide dose-dependently potentiated the stimulant effects of cocaine, in spite of its slight hypolocomotor effect when given alone. Our results strongly suggest that H3 antagonists potentiate the stimulant and reinforcing effects of cocaine in mice. © 2004 Elsevier B.V. All rights reserved. [less ▲]

Thin conductive magnetic shells are accounted for by means of two different time-domain magnetodynamic finite-element formulations, namely the magnetic field formulation and the magnetic vector potential formulation. Both approaches are an extension of the classical linear frequency-domain thin-shell approximation. The interface conditions for the magnetic field formulation and the vector potential formulation are expressed in terms of the average current density and the average flux density, respectively, together with a number of higher-order components of these quantities. The proposed time-domain thin-shell approaches are validated by means of a 3D magnetodynamic problem. The results are shown to agree well with those obtained with a fine model, whereas the computation time is significantly reduced. [less ▲]
