This paper employs dissipativity theory for the global analysis of limit cycles in particular dynamical systems of possibly high dimension. Oscillators are regarded as open systems that satisfy a particular dissipation inequality. It is shown that this characterization has implications for the global stability analysis of limit cycle oscillations: i) in isolated oscillators, ii) in interconnections of oscillators, and iii) for the global synchrony analysis in interconnections of identical oscillators.

Hanoi province, Vietnam has much potential for agricultural development with its large consumer market for agricultural products, soil and water resources, natural climate, physical and social infrastructure. It is also one of provinces that has attracted a large number of investors. However, there are few agriculture investment projects in Hanoi in recent years. This paper presents the results of the structure interview of 200 managers of agricultural firms, co-operatives and farms in Hanoi province in 2008-2009. Even if these enterprises are pleased with their business performance and profitability, the investment climate could have negative effects obstructing investment incentives in agriculture. The study revealed eight key factors determining the investment climate in agriculture in Hanoi province, which include: land issue, provincial policies for agriculture, capital, physical infrastructure, administrative procedures, market, technology and labor issue. Land issues and provincial agricultural policies are the most important constraints; the second group are capital, physical infrastructure, governmental administration; and the third are market, technology and labor issues.

Objectives: To explore the role of muscular strength and imbalance as predisposing factors in the development of anterior knee pain syndrome (AKPS). Methods: 96 male military recruits without history of knee pain volunteered for the study. Each volunteer underwent an isokinetic test prior to the start of a strenuous training program (approximately 8 to 12 hours/day for 6 weeks). The isokinetic test consisted of concentric contractions of the knee flexors and extensors at 60degrees/s and 240degrees/s. A detailed history and clinical examination of the patellofemoral joint was performed on each recruit. Independent sample t-tests were used to compare the isokinetic muscle parameters in recruits who developed AKPS during the training (pathological group) and in those who did not (control group). Binary logistic regression analysis was used to define the predictive outcome of anthropometrics and the isokinetic parameters for the development of AKPS. Results: 31 recruits developed AKPS. Absolute and bodyweight normalized peak extensor torque at 60degrees/s was significantly lower in the pathological group in comparison to the control group. Significant lower peak torque/BMI (Body Mass Index) were also indicated at both velocities. Recruits who developed AKPS had a shorter stature. No regression model could be set up to give any predictive value to the analyzed parameters. Conclusions: Recruits with shorter stature and lower quadriceps strength are more prone to develop AKPS during BMT. However, as the etiology of AKPS is multifactorial these parameters alone may not suffice to predict the occurrence of this pathology. On the other hand, the results of this study emphasize the importance of the reinforcement of quadriceps strength in the treatment and prevention of AKPS. [less ▲]

Human polyomavirus JC DNA was purified directly from the diseased brain tissue of two patients with progressive multifocal leukoencephalopathy (PML) by a method employing differential salt precipitation (B. Hirt, J. Mol. Biol. 26:365-369, 1967). Each of the viral genomes (JC-NIH-1 and JC-NIH-2) was molecularly cloned intact in Escherichia coli, using pBR322, at their unique EcoRI (0.00 map unit) and BamHI (0.51 map unit) sites. The JC-NIH-1 genome was approximately 50 base pairs larger and the JC-NIH-2 genome was approximately 50 base pairs smaller than the prototype human polyomavirus JC (Mad-1) DNA. Analysis of the restriction endonuclease cleavage fragments of these two DNAs and the human polyomavirus JC (Mad-1) DNA revealed only slight differences which mapped in a region of the genome extending from 0.67 to 0.74 map unit. From previous homology studies, this region of variance corresponds to the noncoding region to the late side of the origin of DNA replication. [less ▲]

Introduction Since decades in Wallonia (French speaking part of Belgium), athletics competitions for children are miniaturized versions of adults’ competitions. Despite the fact that it has been pointed out that such kind of approach, based on performance, is not appropriated for motor learning and could result in an increased rate of dropout (1), no change has occurred since years. The International Association of Athletic Federation has developed and promoted a more appropriate model of competition for children under 10 years old: ‘Kids’Athletics’ (KA)(2). While this model is well known, it has not been selected by the Wallonian federation as the gold standard yet . This study aimed to analyze the perceived interest of a group of experts about KA, and to identify the strategies that could be considered for KA implementation in Wallonia. Methods Semi-structured interviews were conducted with 14 athletics or marketing experts (demographic presentation; knowledge about KA and personal experience with KA ; opinion about KA model in comparison with the traditional one, and ; strategies that could be helpful to implement KA in Wallonia). Results Findings showed that 12 experts knew the KA concept while 9 have experimented it in their own club. None mentioned an official competition between clubs. A list of KA’s advantages and disadvantages has been identified (organization, children needs, and development). All experts considered that KA was more adapted to children than traditional competition. Based on subjects’ proposals, a progressive strategy for KA implementation is suggested. It includes the support of the federation and recommends to start with the more convinced clubs. Conclusion This study confirms that KA should be implemented in Wallonia. In order to optimize the chances of success, it would be appropriate to multiply actions, taking into account the potential barriers identified by the experts.

Energy is not always fully randomized in an activated molecule because of the existence of dynamical constraints. An analysis of kinetic energy release distributions (KERDs) of dissociation fragments by the maximum entropy method (MEM) provides information on the efficiency of the energy flow between the reaction coordinate and the remaining degrees of freedom during the fragmentation. For example, for barrierless cleavages, large translational energy releases are disfavoured while energy channeling into the rotational and vibrational degrees of freedom of the pair of fragments is increased with respect to a purely statistical partitioning. Hydrogen atom loss reactions provide an exception to this propensity rule. An ergodicity index, F, can be derived. It represents an upper bound to the ratio between two volumes of phase space: that effectively explored during the reaction and that in principle available at the internal energy E. The function F(E) has been found to initially decrease and to level off at high internal energies. For an atom loss reaction, the orbiting transition state version of phase space theory (OTST) is especially valid for low internal energies, low total angular momentum, large reduced mass of the pair of fragments, large rotational constant of the fragment ion, and large polarizability of the released atom. For barrierless dissociations, the major constraint that results from conservation of angular momentum is a propensity to confine the translational motion to a two-dimensional space. For high rotational quantum numbers, the influence of conservation of angular momentum cannot be separated from effects resulting from the curvature of the reaction path. The nonlinear relationship between the average translational energy <epsilon > and the internal energy E is determined by the density of vibrational-rotational states of the pair of fragments and also by non-statistical effects related to the incompleteness of phase space exploration. The MEM analysis of experimental KERDs suggests that many simple reactions can be described by the reaction path Hamiltonian (RPH) model and provides a criterion for the validity of this method. Chemically oriented problems can also be solved by this approach. A few examples are discussed: determination of branching ratios between competitive channels, reactions involving a reverse activation barrier, nonadiabatic mechanisms, and isolated state decay.

The Suusamyr region is located in the northern part of the Tien Shan Range in Central Asia. In 1992, this region was hit by the Ms = 7.3 Suusamyr earthquake triggering several large landslides along the Suusamyr Valley and on the southern slopes of the adjacent Suusamyr Range. One of these landslides had been investigated by geophysical and geotechnical methods in order to determine local trigger factors. The present paper focuses on the influence of geological and morphological factors upon landslide occurrence on a regional scale. The analysis is based on a digital data set including landslides triggered in 1992 and several older landslides as well as various types of digital elevation models (DEMs), ASTER image data, and geological and active fault maps. These data were combined to compute landslide susceptibility (LS) maps using statistical methods, Landslide Factor and Conditional Analyses (LFA, CA), as well as a geotechnical one, the Newmark's Method (NM). The landslide data set was also analyzed with respect to the size-frequency relationship. [less ▲]

In the Ardenne region, old maps of different periods indicate that the layout of major rivers has been relatively stable since the end of the 18th century. However, given the scale of the different documents and the relative inaccuracy of their georeferencing, it is not possible to precisely measure the rivers’ lateral erosion or to study the dynamic of small rivers. Moreover, maps older than the 18th century are not precise enough to permit this type of approach. Quantities of slag elements are present in the Ardenne rivers. These waste products come from hundreds of ironworks (blast furnaces and bloomeries) built close to different-sized rivers between the 14th and the 19th centuries. Slag was piled onto the floodplains and frequently thrown out directly into the rivers. For centuries, these slag elements were carried away during floods and were spread out along rivers. Given their properties, slag elements can be easily identified in sediments. When the slag elements are present in fine sediments at the point of contact with the gravel sheet, it means that the river has moved laterally since the inception of the iron industry, swept away older sediments and deposited more recent sediments contaminated by the slag. From historical studies, we precisely dated the periods of ironwork activity in several valleys. We also analysed the vertical concentrations of slag elements in several borings carried out along perpendicular cross sections. These data allowed us to estimate the lateral erosion velocity of some channels over several centuries. Moreover, we reconstructed the topography of several alluvial plains at the time ironworks were established and we evaluated sedimentation rates. [less ▲]

Lateral mobility of Ardenne rivers has been studied at different scales using three complementary methods. We firstly compared the layout of channels on topographic maps (since the 18th century) and aerial pictures. Given that these documents have different scales and projection systems, they were transformed into a common referencing system. This method allowed us to study the lateral shifting of channels, however, as the mobility of Ardenne rivers is relatively low, the errors of geometric rectifications are often more important than lateral displacements. Therefore, to visualize these deformations, georeferenced documents were overlaid with a regular grid of points. We represented the imprecision vector based on x and y residual components for each point. These vectors show the direction of the deformation and its amplitude. Large quantities of iron slag are present in the sediments of Ardenne rivers. These waste products come from hundreds of ironworks built close to rivers since the 14th century. Analyses of slag concentrations in alluvial deposits allowed us to delimitate the sectors of floodplains eroded by rivers during the last centuries. In these sectors, slag elements are present at the contact with the gravel sheet. Finally, we analysed the topography of floodplains from a DEM-LIDAR. This digital elevation model has been established by the Walloon Region for the cartography of flood risk in floodplains. It presents a Z mean error of only 15 cm and a X-Y resolution of 1 m. In order to reveal paleochannels and topographic alluvial units, we subtracted a surface, corresponding to the longitudinal water surface slope, extracted from the DEM. By using this method, we are able to obtain the relative height of any point of the floodplain with regard to the water surface, projected perpendicularly to the layout, on this point. This procedure reveals paleochannels even if they are almost infilled and allows us to delimitate, for several kilometres, alluvial units, which have been formed at different periods. [less ▲]

A first part of the paper deals with single degree of freedom (SDOF) systems, with a particular emphasis on the resolution of the non linear equation allowing to compute the damping force corresponding to a given velocity. A second part deals with multi degree of freedom (MDOF) systems, and presents a special algorithm to study the behaviour of structures with a very small number of non linear components. [less ▲]
