Three-dimensional numerical analysis of jack-up structures on sand (2002)

As jack-ups have moved into deeper and harsher waters there has been an increased need to understand jack-up behaviour and develop analysis techniques. One of the areas of significant development has been the modelling of spudcan footing performance, where the load-displacement behaviour of the footings is required to be included in any overall numerical model. Due to their ability to be incorporated into conventional structural analysis programs strain-hardening plasticity models are appropriate replacements to the unrealistic assumptions of pinned and linear spring footings. Suggested models include B for the analysis of spudcans on clay (Martin, 1994; Martin and Houlsby, 2001) and for dense sand (Cassidy, 1999; Houlsby and Cassidy, 2002). However, these models only describe the load-displacement behaviour of spudcan footings for three degrees of freedom (vertical, moment and horizontal) and therefore can only be applied in two-dimensional (plane-frame) structural analysis. This paper outlines a possible theoretical extension to Model C to account for six degrees of freedom (vertical, orthogonal moment and horizontal, and torsion). This formulation allows it to be implemented in three-dimensional structural analysis programs. An example of this is given, with the analysis of a three-dimensional jack-up detailed.
Early growth response‐1 transcription factor promotes hepatic fibrosis and steatosis in long‐term ethanol‐fed <scp>L</scp>ong‐<scp>E</scp>vans rats (2012)

Long-term ethanol feeding promoted steatosis and fibrosis in LE rats via EGR1 activation. The highly abundant EGR1 bound to the SREBP1c promoter and contributed to the steatosis observed in the LE rat model.
Differences in fat accumulation between immature male and female Atlantic salmon <i>Salmo salar</i> after dietary administration of tetradecylthioacetic acid (2016)

This study provoked sex-specific differences in fat metabolism in Atlantic salmon Salmo salar, by dietary administration of tetradecylthioacetic acid (TTA) during their first spring and winter in the sea. The effects of TTA were evaluated in June of the first spring and May of the second spring in the sea, by analysing white muscle-fat content. Muscle fat in males and females differed significantly as a result of TTA in their diet and diet interacted with the sex of the fish. The fat content during the first spring after dietary TTA was lowered by a greater amount in females than in males, 3·1-4·3%, respectively (P < 0·05). In contrast, during the second spring, fat content was lowered by a greater amount in males than in females, 15·8-16·7%, respectively (P < 0·01). Condition factor followed a similar pattern to the muscle fat. The results indicate that the difference in male and female fat accumulation dynamics is related to sex-specific reproduction biology of S. salar. In addition, the findings show that it is important to consider the sex of the fish and the season of the year when studying fat dynamics and reproductive biology of S. salar.
Active control of sound fields in elastic cylinders by vibrational inputs (1987)

An experiment is performed to study the mechanisms of active control of sound fields in elastic cylinders via vibrational outputs. In the present method of control, a vibrational force input was used as the secondary control input to reduce the radiated acoustic field. For the frequencies considered, the active vibration technique provided good global reduction of interior sound even though only one actuator was used.

Al30: A Giant Aluminum Polycation (2000)

Simple hydrothermal treatment of the well-known aluminum polycation varepsilon-Al(13) produces the novel Al(30) structure (see picture), the largest polycation yet observed. Its characterization, by X-ray diffraction and NMR spectroscopy, also solved previously unassigned signals in (27)Al NMR spectra of other Al - O species.
Extracranial aneurysms of the distal posterior inferior cerebellar artery: Resection and primary reanastomosis as the preferred management approach (2013)

Resection and primary reanastomosis of extracranial distal PICA aneurysms averts the risk of clip dislodgement due to neck movement and/or compression by soft tissues in the upper cervical region. It is a safe and efficacious technique, which we propose as the preferred management strategy for these rare vascular lesions.
The Effect of the Austenitisation Temperature on the Transformation Kinetics of an Nb-Containing Steel (1998)

An experimental study on the effect of the austenitisation temperature on the austenite decomposition for an Nb-microalloyed steel is performed by means of Differential Thermal Analysis. The start temperature for the formation of allotriomorphic ferrite in a cooling experiment depends strongly on the austenitisation temperature through the austenite grain size. The austenite grain size in its turn depends on the austenitisation temperature and is strongly restricted by the presence of NbC-precipitates. Also the transformation rates depend on the presence and/or formation of NbC-precipitates. Precipitation of NbC during the phase transformation, likely to take place at the austenite/ferrite interface, reduces the effective transformation rate, in some cases leading to the formation of Widmannstatten ferrite and bainite.
Topography of cat medullary ventral surface hypoxic acidification (1992)

The topographic relationship between previously identified medullary ventral surface respiratory chemosensitive regions and brain surface extracellular fluid (ECF) acid production during acute hypoxia was explored in anesthetized, paralyzed, and artificially ventilated cats. Glass pH electrodes (0.8-mm diam, sheathed in stainless steel tubing) were mounted in mechanical contact with surfaces of medullary surface or adjacent pyramids, pons, spinal cord, or parietal cortex. Isocapnic hypoxia of 5 min [at arterial O2 saturation (SaO2) = 48 +/- 10%] reduced pH over rostral (Mitchell) and caudal (Loeschcke) areas by 0.12 +/- 0.09 and 0.07 +/- 0.04, respectively (n = 10, P < 0.05). Change in pH (delta pH) was proportional to desaturation with slopes 100 delta pH/delta SaO2 of 0.45 (rostral) and 0.20 (caudal) (R = 0.91 and 0.88, respectively). pH drop usually began within 3 min of hypoxia, became stable between 5 and 15 min, began to rise within 2 min of reoxygenation, and returned to control within 10 min. During equally hypoxic tests, intermediate area (Schläfke), pons, and spinal cord surfaces showed no significant acid shift. Parietal cortex ECF pH dropped more slowly but steadily by 0.079 +/- 0.034 during 20 min at SaO2 = 50% after a small but significant initial alkaline shift, and acidification of cortical surface continued for > 5 min after reoxygenation. We conclude that medullary ventral chemosensitive regions produce more lactic acid during hypoxia than neighboring brain surfaces.(ABSTRACT TRUNCATED AT 250 WORDS)
Functional CD40 ligand is expressed by T cells in rheumatoid arthritis. (1997)

CD40 ligand (CD40-L), a member of the tumor necrosis family of transmembrane glycoproteins, is rapidly and transiently expressed on the surface of recently activated CD4+ T cells. Interactions between CD40-L and CD40 induce B cell immunoglobulin production as well as monocyte activation and dendritic cell differentiation. Since these features characterize rheumatoid arthritis (RA), the expression and function of CD40-L in RA was examined. Freshly isolated RA peripheral blood (PB) and synovial fluid (SF) T cells expressed CD40-L mRNA as well as low level cell surface CD40-L. An additional subset of CD4+ RA SF T cells upregulated cell surface CD40-L expression within 15 min of in vitro activation even in the presence of cycloheximide, but soluble CD40-L was not found in SF. CD40-L expressed by RA T cells was functional, since RA PB and SF T cells but not normal PB T cells stimulated CD40-L-dependent B cell immunoglobulin production and dendritic cell IL-12 expression in the absence of prolonged in vitro T cell activation. In view of the diverse proinflammatory effects of CD40-L, this molecule is likely to play a central role in the perpetuation of rheumatoid synovitis. Of importance, blockade of CD40-L may prove highly effective as a disease modifying therapy for RA.
An Efficient Technique for Motion Recovery Based on Multiple Views. (1998)

The factorization method is a technique for recovering 3-D shape of an undeformable object without using camera parameters. The technique is extended to an efficient method in this paper for recovering 3-D motion of a deformable object, i.e., a human. The proposed system is composed of three fixed video cameras which take video images of a human motion. Three obtained image sequences are analyzed to yield measurement matrices at individual sampling times, and they are merged into a single measurement matrix to which the factorization is applied and the 3-D human motion is recovered at a time. Experimental results were satisfactory.
Peroxynitrite-Mediated Protein Nitration and Lipid Peroxidation in a Mouse Model of Traumatic Brain Injury (2004)

The role of reactive oxygen-induced oxidative damage to lipids (i.e., lipid peroxidation, LP) and proteins has been strongly supported in previous work. Most notably, a number of free radical scavengers and lipid antioxidants have been demonstrated to be neuroprotective in traumatic brain injury (TBI) models. However, the specific sources of reactive oxygen species (ROS), the time course of oxidative damage and its relationship to post-traumatic neurodegeneration in the injured brain have been incompletely defined. The present study was directed at an investigation of the role of the ROS, peroxynitrite (PON), in the acute pathophysiology of TBI and its temporal relationship to neurodegeneration in the context of the mouse model of diffuse head injury model. Male CF-1 mice were subjected to a moderately severe head injury and assessed at 1-, 3-, 6-, 12-, 24-, 48-, 72, 96- and 120-h post-injury for neurodegeneration using quantitative image analysis of silver staining and semi-quantitative analysis of PON-mediated oxidative damage to proteins (3-nitrotyrosine, 3-NT) and lipids (4-hydroxynonenal, 4-HNE). Significant evidence of silver staining was not apparent until 24-h post-injury, with peak staining seen between 72- and 120-h. This time-course of neurodegeneration was preceded by intense immunostaining for 3-NT and 4-HNE, which occurred within the first hour post-injury. The time course and staining pattern for 3-NT and 4-HNE were similar, with the highest staining intensity noted within the first 48-h in areas surrounding trauma-induced contusions. In the case of 3-NT, neuronal perikarya and processes and microvessels displayed staining. The temporal and spatial coincidence of protein nitration and LP damage suggests that PON is involved in both. However, lipid-peroxidative (4-HNE) immunoreactivity was broader and more diffuse than 3-NT, suggesting that other reactive oxygen mechanisms, such as iron-dependent LP, may also contribute to the more widespread 4-HNE immunoreactivity. This indicates that optimal pharmacological inhibition of post-traumatic oxidative damage in TBI may need to combine two functionalities: one to scavenge PON or PON-derived radicals, and the second to inhibit LP caused by multiple ROS species.

Simulation Models For Evaluating The IntegrationOf DC Railway Power Feeding Systems And TrainDispatching Systems (1970)

Contrary to the common belief, signalling system is of little importance in the implementation of simulation model for evaluation of dc power feeding systems. This is because there is little need for consideration of fluctuation in train operations if the program is used for optimal design of the system. In general, signalling system is only necessary if fluctuation is considered. On the other hand, however, the authors have shown that there are many possibilities in the integration of power feeding and train dispatching systems. Naturally, many optimization strategies for the integrated system should be evaluated. Since the role of train dispatching system is to cope with unexpected operational situations, various kinds of fluctuation in train operations should be considered in the evaluation, and implementation of signalling system becomes important. The authors propose a promising strategy of avoiding intermediate stops of trains, and reveal its possibility with some simulation results obtained by the authors' simulation program called RTSS.
The C Terminus of SecA Is Involved in Both Lipid Binding and SecB Binding (1995)

Using C-terminal deletion mutations in secA, we localized the previously proposed (Breukink, E., Keller, R.C. A., and de Kruijff, B. (1993), FEBS Lett. 331, 19-24) second lipid binding site on SecA. Since removal of these residues completely abolished the property of SecA to cause aggregation of negatively charged phosphatidyl-glycerol vesicles, we conclude that the C-terminal 70 amino acid residues of SecA are involved in lipid-binding. The C-terminal 70 amino acid residues of SecA are important for efficient in vitro translocation of the SecB-dependent precursor of PhoE across inverted inner membrane vesicles. Moreover, in vivo studies showed that this region is essential for growth. SecB and a SecB-precursor complex were shown to inhibit the SecA-mediated lipid vesicle aggregation, suggesting that the overall acidic SecB protein binds at or near the second lipid binding site on SecA. This together with the observation that the SecA mutant protein lacking the C-terminal 70 residues had a strongly reduced ability to mediate binding of SecB-precursor complexes to inverted inner membrane vesicles demonstrates that the C terminus of SecA is also involved in SecB binding.
Kidneys extract BNP and NT-proBNP in healthy young men (2005)

Renal metabolism of the cardiac marker NH2-terminal-pro-brain natriuretic peptide (NT-proBNP) has been suggested. Therefore, we determined the renal extraction ratios of NT-proBNP and its bioactive coproduct brain natriuretic peptide (BNP) at rest and during exercise. In addition, the cerebral ratios were evaluated. Ten young healthy men were investigated at baseline, during moderate cycle exercise (heart rate: 140, Borg scale: 14-15), and in the recovery with BNP and NT-proBNP measured from the brachial artery and the jugular and renal veins, and the renal and cerebral extraction ratios (Ext-Ren and Ext-Cer, respectively) were calculated. Cardiac output, stroke volume, heart rate, mean arterial pressures, and estimated glomerular filtration were determined. BNP and NT-proBNP were extracted by the kidneys but not by the brain. We observed no effect of exercise. The mean values (+/- SE) of Ext-Ren of NT-proBNP were similar (0.19 +/- 0.05, 0.21 +/- 0.06, and 0.12 +/- 0.03, respectively) during the three sessions (P > 0.05). Also the Ext-Ren of BNP were similar (0.18 +/- 0.07, 0.15 +/- 0.11, and 0.14 +/- 0.06, respectively; P > 0.05). There were no significant differences between Ext-Ren of BNP and NT-proBNP during the three sessions (P > 0.05). The Ext-Cer of both peptides varied insignificantly between -0.21 +/- 0.15 and 0.11 +/- 0.08. The renal extraction ratio of both BNP and NT-proBNP is approximately 0.15-0.20. There is no cerebral extraction, and short-term moderate exercise does not affect these values. Our findings suggest that the kidneys extract BNP and NT-proBNP to a similar extent in healthy young men.
Past Experience Supports Future Choices for Cropping Systems Management: The Italian Long-Term Agro-Ecosystem Experiments (LTAE) through the IC-FAR Project and the Maggnet International Network (2016)

Does the available data from long-term agro-ecosystem experiments (LTAE) provide a useful platform to understand and model the long term dynamics of cropping system functions and services and to assess the cropping systems resilience in response to climate change? What insights can be gained and transformed into agronomic practices by connecting the LTAE managers with the crop modelling research community? What further data are needed for integrating the available LTAE data for enhancing the cropping systems models’ domain? Are the old LTAEs, designed many years ago, still useful to address nowadays cropping system research questions and challenges posed by Climate Change?\nThe IF-CAR research project (2013-16, www.icfar.it) provided answers to these questions from the analyses of sixteen LTAEs, located in six locations over an N-S transect across Italy. These experiments were originally designed to study the long term effects of different crop management practices on soil organic carbon and nitrogen dynamics and crop yield.\nIn IC-FAR, LTAE data were harmonized in a database and were used to calibrate several simulation models (DSSAT, EPIC, SALUS, CropSyst, CSS, Cycles, RothC). With the mission of fostering data sharing and collaboration, the IC-FAR database is compatible with international databases (e.g. AgMIP, MACSUR) and is shared with the MAGGnet international network for the mitigation of agricultural greenhouse gases.\nThe results of this research showed that the LTAE are an invaluable source of information to assess the long-term sustainability of cropping systems. LTAE data coupled with cropping systems simulation models were effectively used to assess the potential of adaptive and mitigation crop management strategies addressing the resilience issues posed by climate change.

Ureteral endometriosis (2001)

Objective To evaluate the prevalence of ureteral endometriosis and to describe the laparoscopic surgery. Design This is a prospective study. Results In a series of 306 patients with rectovaginal adenomyotic nodules, preoperative intravenous pyelography revealed ureteral stenosis with ureterohydronephrosis in 14 cases (4.5%). In four patients, complete ureteral stenosis was observed, and kidney scintigraphy revealed damaged kidney parenchymal function varying from 18% to 42%. Laparoscopic ureterolysis was possible in 13 women, and a significant postoperative decrease in ureterohydronephrosis was noted. In only one case, ureteral resection and uretero‐ureterostomy were needed. Conclusion In cases of rectovaginal adenomysois more than 3 cm, the prevalence of ureteral endometriosis is high. The preoperative IVP is needed before laparoscopic ureterolysis which will avoid the silent loss of real function.
Functional Outcome of Neurologic-Controlled HAL-Exoskeletal Neurorehabilitation in Chronic Spinal Cord Injury: A Pilot With One Year Treatment and Variable Treatment Frequency (2017)

Long-term 1-year maintenance of HAL-associated treadmill walking parameters and of improved independent walking abilities after initial 12 weeks of daily HAL-BWSTT is possible and depends mainly on the patients' ambulatory status accomplished after initial training period. Subsequent regular weekly training, but not higher frequency training, seems to be sufficient to preserve the improvements accomplished.

Experimental Investigation of an Ultrathin Manifold Microchannel Heat Sink for Liquid-Cooled Chips (2010)

We report an experimental investigation of a novel, high performance ultrathin manifold microchannel heat sink. The heat sink consists of impinging liquid slot-jets on a structured surface fed with liquid coolant by an overlying two-dimensional manifold. We developed a fabrication and packaging procedure to manufacture prototypes by means of standard microprocessing. A closed fluid loop for precise hydrodynamic and thermal characterization of six different test vehicles was built. We studied the influence of the number of manifold systems, the width of the heat transfer microchannels, the volumetric flow rate, and the pumping power on the hydrodynamic and thermal performance of the heat sink. A design with 12.5 manifold systems and 25 μm wide microchannels as the heat transfer structure provided the optimum choice of design parameters. For a volumetric flow rate of 1.3 l/min we demonstrated a total thermal resistance between the maximum heater temperature and fluid inlet temperature of 0.09 cm2 K/W with a pressure drop of 0.22 bar on a 2×2 cm2 chip. This allows for cooling power densities of more than 700 W/cm2 for a maximum temperature difference between the chip and the fluid inlet of 65 K. The total height of the heat sink did not exceed 2 mm, and includes a 500 μm thick thermal test chip structured by 300 μm deep microchannels for heat transfer. Furthermore, we discuss the influence of elevated fluid inlet temperatures, allowing possible reuse of the thermal energy, and demonstrate an enhancement of the heat sink cooling efficiency of more than 40% for a temperature rise of 50 K.
Frequency adaptive repetitive control of grid-tied single-phase PV inverters (2015)

The internal model principle based Repetitive Control (RC) offers an accurate control strategy for grid-tied power converters to feed sinusoidal current into the grid. However, in the presence of grid frequency variations, the conventional RC fails to produce high quality feeding current. This paper thus explores a frequency adaptive repetitive control strategy for grid converters, which employs fractional delay filters in order to adapt to the change of the grid frequency. Case studies with experimental results of a single-phase grid-connected PV inverter system are provided to verify the proposed controller.
