description: A detailed analysis of the classical nonlinear dynamics of a single driven square potential barrier with harmonically oscillating position is performed. The system exhibits dynamical trapping which is associated with the existence of a stable island in phase space. Due to the unstable periodic orbits of the KAM-structure, the driven barrier is a chaotic scatterer and shows stickiness of scattering trajectories in the vicinity of the stable island. The transmission function of a suitably prepared ensemble yields results which are very similar to tunneling resonances in the quantum mechanical regime. However, the origin of these resonances is different in the classical regime.

description: RELATIONSHIP BETWEEN FEEDING OF DAIRY COWS DURING THE DRY PERIOD AND METABOLIC DISTURBANCES AFTER CALVING A total of 36 HF cows divided into 3 groups with the same mean age and the same milk yield average but receiving different roughages during the dry period were studied as regards to metabolic disturbances in early lactation. At the beginning of the dry period, the mean fattening score of the three groups was 3,5 on INRA's scoring board. At the calving, the fattening scores were respectively 5, 4 and 3,5 for groups n° 1, n° 2 and n° 3. Metabolic diseases in the first group included the following Ketosis 5/12; milk fever 4/12 and displaced abomasum 2/12. The cows of the groups n° 1 and n° 3 did not present any sign of metabolic disturbances. Feeding corn-silage ad libitum during the dry period appears to be dangerous because the overfattening increases the incidence of ketosis and other metabolic diseases in early lactation. The author concludes that rations with high level of fiber and low level of energy are better during the dry period. Article in French, English summary on PDF

description: The importance of clinical lameness in dairy cows is receiving increasing recognition. In addition to treatment and prevention costs, culling, milk production, and reproduction losses may occur due to lameness. The moral cost of animal suffering during severe lameness episodes must also be considered. Despite this, recommended management practices for the purpose of lameness prevention at the cow and herd level are often based upon trial and error rather than sound research-based knowledge of causal mechanisms of lameness. This has been due in part to the sparcity of lameness research in cattle. In addition, much of the available literature on lameness has been based upon a subjective diagnosis of lameness without a standard case definition, and often using multiple observers (producers) leading to difficulty in interpretation. The result has been a scarcity of useful information for veterinarians and producers. The objective of this study included evaluation of within herd risk factors (bodyweight, body condition score, dorsal claw angles, visible and palpable limb lesions, and antibody to Borrelia burgdorferi) and between herd risk factors (housing, flooring, dietary, and management practice) for clinical lameness in lactating dairy cows.

description: The formation and evolution process and magnetic configuration of solar prominences remain unclear. In order to study the formation process of prominences, we examine continuous observations of a prominence in NOAA AR 10953 with the Solar Optical Telescope on the \emph{Hinode} satellite. As reported in our previous Letter, we find a signature suggesting that a helical flux rope emerges from below the photosphere under a pre-existing prominence. Here we investigate more detailed properties and photospheric indications of the emerging helical flux rope, and discuss their relationship to the formation of the prominence. Our main conclusions are: (1) A dark region with absence of strong vertical magnetic fields broadens and then narrows in Ca \textsc{ii} H-line filtergrams. This phenomenon is consistent with the emergence of the helical flux rope as photospheric counterparts. The size of the flux rope is roughly 30,000 km long and 10,000 km wide. The width is larger than that of the prominence. (2) No shear motion or converging flows are detected, but we find diverging flows such as mesogranules along the polarity inversion line. The presence of mesogranules may be related to the emergence of the helical flux rope. (3) The emerging helical flux rope reconnects with magnetic fields of the pre-existing prominence to stabilize the prominence for the next several days. We thus conjecture that prominence coronal magnetic fields emerge in the form of helical flux ropes that contribute to the formation and maintenance of the prominence.

Environmental Problems Induced by Cattle Farming in the Po Valley (Northern Italy)

Year: 1992

description: This paper deals with the enviromental impact deriving from the presence of widespread farming activities in the Po Valley which, owing to its geologic characteristics, is particularly vulnerable to pollutants. From the schematic hydrogeologic map of the Po Plain shown in the text, the prevailing presence of alluvial deposits is evident. These deposits, due to their grain-size characteristics, are often interested by the presence of vast amounts of groundwaters which are an important resource for man since they are widely exploited for watersupply and irriguous purposes. The high permeability of a great part of these deposits makes them particularly vulnerable to pollutants, also considering that the Po Valley shows one of the highest concentrations of industry and farming not only in Italy but in the whole of Western Europe. In particular, for what concerns animal breeding, the data collected show that the pollutants' load derives mainly from cattle farms which are, therefore, one of the main sources of potential pollution of the aquifers. Indeed, the hydrochemical analysis of groundwaters in the Po Valley has confirmed in many cases the presence of pollutant concentrations above legal levels, owing to an inadequate management of farm-sewage. In order to upgrade the environmental situation it is necessary to apply strictly the existing norms and to improve the depuration and waste-disposal techniques aiming at a management more compatible with the physical characteristics of the territory.

description: Die Grüne Branche erlebt in den letzten Jahren – nicht zuletzt wegen der Klima- und Energiekrise – einen Aufschwung. Mit der Digitalisierung kommen neue Chancen und Herausforderungen auf die Grüne Branche zu. Um erfolgreich in die digitale Zukunft zu gehen, ist es wichtig, die richtigen Tools und Use Cases zu kennen. Im Vorgängerprojekt „Green BIM Bauwerksbegrünung als Teil BIM-basierter Planung und Pflege“ wurden basierend auf einer umfassenden Status-Quo-Analyse von bestehenden Gebäudebegrünungen die Kriterien für eine BIM-basierte Planung über den gesamten Lebenszyklus (Planung, Ausführung, Pflege, Wartung) ausgearbeitet. Ein Entwurf für eine „Green BIM IFC-Datenstruktur“ mit zugehörigen Informationen zum buildingSMART Data Dictionary (bsDD), den spezifischen Anforderungen des Auftraggebers und möglichen Anwendungsfällen wurde ebenfalls entwickelt. Das aktuelle Projekt, „Green BIM 2: Green Information Modelling and Operation – Transformation der Grünen Branche durch Digitalisierung" (Laufzeit 06/2023 bis 12/2025), baut auf "Green BIM" auf und führt u.a. einen Praxis Proof der Ergebnisse aus Green BIM durch und erweiterter den IFC-Datenstruktur-Vorschlag um die gesamte Landschaftsplanung, welches die Anwendung von BIM im Bereich der Bauwerksbegrünung erforschte. Die Summer School 2024 bietet die Gelegenheit, diese Inhalte an die Teilnehmenden weiter zu geben, darüber zu reflektieren und dann in der Praxis anzuwenden. In einem zweiwöchigen Kurs erhalten die Teilnehmenden die Möglichkeit Vorträge zu besuchen, Übungen zur Modellierung und zum Datenmanagement durchzuführen, gemeinsam Exkursionen zu Gebäuden mit Bauwerksbegrünung zu machen und ein selbstständiges Projekt zu entwickeln und am Ende des Kurses den restlichen Teilnehmenden und Vortragenden zu präsentieren.

description: Lameness in dairy cattle can lead to weight loss, reduced milk production and reproductive problems. In an effort to investigate a lameness problem in a Pennsylvania dairy herd, a form was developed to objectively assess herd management and cow disease status that could be used to investigate the outbreak of herd lameness. Use of these forms, coupled with Dairy Herd Improvement Association production records and ration evaluations can be used to generate hypotheses for causes of herd lameness problems.

description: We address the problem of quantifying the non-Markovian character of quantum time-evolutions of general systems in contact with an environment. We introduce two different measures of non-Markovianity that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts. When complete tomographic knowledge about the evolution is available, our measure provides a necessary and sufficient condition to quantify strictly the non-Markovianity. In the opposite case, when no information whatsoever is available, we propose a sufficient condition for non-Markovianity. Remarkably, no optimization procedure underlies our derivation, which greatly enhances the practical relevance of the proposed criteria.

description: Lamivudine is a first-line medication used for human immunodeficiency virus (HIV) treatment. To date, the population pharmacokinetics of lamivudine in Chinese HIV-infected adults have not been assessed. This study aimed to develop a population pharmacokinetic model for oral lamivudine in Chinese HIV-infected adults and to determine the optimal lamivudine dosage regimens. A total of 1113 samples, from 828 Chinese HIV-infected patients treated with lamivudine 300 mg every 24 hours, were pooled from two open-label, prospective clinical trials. A population pharmacokinetics analysis was performed using a nonlinear mixed-effects modeling method. A Monte Carlo simulation was conducted to optimize lamivudine dosing. A two-compartment model adequately described the population pharmacokinetics of lamivudine. The typical population estimate for apparent clearance was 28.3 L/h. Creatinine clearance was identified as a significant factor influencing apparent clearance. According to the Monte Carlo simulation, patients with creatinine clearance between 50 and 70 mL/min should receive lamivudine 200 mg every 24 h or 300 mg every 36 h, to achieve optimal lamivudine exposure. No obvious ethnic differences were observed in lamivudine pharmacokinetics between Chinese and Caucasian populations. Additionally, a model-informed dosage regimen is recommended for patients with impaired renal function.

We call an equation of such kind Darboux integrable, if there exist two functions (called integrals) $F$ and $I$ of a finite number of dynamical variables such that $D_xF=0$ and $DI=I$, where $D_x$ is the operator of total differentiation with respect to $x$, and $D$ is the shift operator: $Dp(n)=p(n+1)$. It is proved that the integrals can be brought to some canonical form. A method of construction of an explicit formula for general solution to Darboux integrable chains is discussed and for a class of chains such solutions are found.

description: Biotechnological production of recombinant molecules relies heavily on fed-batch processes. However, as the cells' growth, substrate uptake, and production kinetics are often unclear, the fed-batches are frequently operated under sub-optimal conditions. Process design is based on simple feed profiles (e.g., constant or exponential), operator experience, and basic statistical tools (e.g., response surface methodology), which are unable to harvest the full potential of production. To address this challenge, we propose a general modeling framework, OptFed, which utilizes experimental data from non-optimal fed-batch processes to predict an optimal one. In detail, we assume that cell-specific rates depend on several state variables and their derivatives. Using measurements of bioreactor volume, biomass, and product, we fit the kinetic constants of ordinary differential equations. A regression model avoids overfitting by reducing the number of parameters. Thereafter, OptFed predicts optimal process conditions by solving an optimal control problem using orthogonal collocation and nonlinear programming. In a case study, we apply OptFed to a recombinant protein L fed-batch production process. We determine optimal controls for feed rate and reactor temperature to maximize the product-to-biomass yield and successfully validate our predictions experimentally. Notably, our framework outperforms RSM in both simulation and experiments, capturing an optimum previously missed. We improve the experimental product-to-biomass ratio by 19% and showcase OptFed's potential for enhancing process optimization in biotechnology.

description: The major economic importance of neonatal infectious diarrhoeas in calves have justified for a few years the development of control programmes combining both sanitary and medical aspects [7]. The importance of immunity conferred through colostrum and milk has been demonstrated [1] [2] [8]. The vaccination of pregnant cows revealed, in the field, as the most efficient mean to reach a high colostrum and milk immunity [3] [4] [5] [10]. The etiology of neonatal infectious diarrhoeas in cattle is now well-determined different types of colibacilli having well-characterized attachment or virulence factors are now isolated; viruses, rotavirus and coronavirus, have also been evidenced [6] [9] [11] [12]. The authors present the results obtained during a controlled clinical trial by using an inactivated vaccine, adjuvanted with aluminium hydroxyde and saponin. This vaccine is indicated for vaccination of pregnant cows.

description: On account of the economic importance of the BVD-MD syndrome in cattle significant studies were performed concerning sanitary and medical prophylaxis. As far as medical prophylaxis is concerned, attenuated live and inactivated virus vaccines have been used in cattle [1] [4]. The safety of attenuated life vaccines has been considered doubtful more particularly in reproductive females. The efficacy of inactivated vaccines depends on the nature of the strains used and of the adjuvant [3) [4]. The results obtained with an inactivated vaccine in oil adjuvant so as to prevent the infection in breeding animals are presented by the authors.

description: We argue that a classical inequality due to Fan, Taussky and Todd (1955) is equivalent to the dissipativity of a Jordan block. As the latter can be characterised via the zeros of Chebyshev polynomials, we obtain a short new proof of the inequality. Three other inequalities of Fan–Taussky–Todd are reproven similarly. By the Lumer–Phillips theorem, the matrix semigroup generated by the Jordan block is contractive. This yields new extensions of the classical Fan–Taussky–Todd inequalities. As applications, we give an estimate for the partial sums of a Bessel function, and a contribution to the classification of self-similar Gaussian Markov processes.

description: In Phys. Rev. Lett. 99, 170502 (2007) (arXiv:quant-ph/0703227), we prove that resonating-valence-bond (RVB) states on arbitrary lattices possess genuine multiparty entanglement, and provide bounds on two-particle entanglement (and correlators). We also conjecture on the entanglement in large and small portions of the whole lattice. The proof, bound, and conjecture are not considered in the Comment in Phys. Rev. Lett. 101, 248901 (2008) (arXiv:0812.1932v1 [quant-ph]). Next we take two examples: "RVB gas" and "RVB liquid". RVB liquid for arbitrary lattice size is not considered in the Comment. Two-party entanglement of RVB gas for relatively large lattice size is derived by an independent method in the Comment, and it agrees with our result. Multi-party entanglement of RVB gas is not considered in the Comment. Lastly, we consider an RVB liquid on a 4x4 square lattice and there was an error in the calculation of two-party entanglement in the second decimal place, as noted in the Comment. Note that this calculation was nowhere used in our Letter to derive other results. Moreover, the conclusion of "no two-particle entanglement" is still true for the RVB liquid on a 4x4 square lattice.

description: In gauge theories in the limit of a large number Nc of colors, baryons are usually described as heavy solitonic objects with mass of order Nc. We discuss an alternative large Nc description both directly in the field theory as well as using holography. In this alternative large Nc limit at least some of the baryons behave like mesons, that is they stay light even at large Nc and their interactions vanish in that limit. For Nc=3 these alternative large Nc baryons are equivalent to the standard baryons. In the holographic description it is manifest that the Regge slopes of mesons and alternative baryons are degenerate.

description: The parturient cow is highly susceptible to environmental mastitis. Severe clinical mastitis may occur shortly after parturition and is more severe than most cases of mastitis occurring in mid and late lactation periods (3). The enhanced susceptibility to mastitis may be attributable to the suppression of host defense mechanisms (3,4). The function of neutrophils is important for protection in the early phase of infection. However, little data are available on the function of neutrophils in dairy cows during the perinatal period (6, 7,10). Immunomodulators that might abrogate the development of periparturient immunosuppression have not been evaluated. Dihydroheptaprenol (DHP) is a polyprenol derivative and is known as a stimulator of neutrophils under experimental systems of mice (1,11) and swine (2). The present study was performed to determine whether DHP administration alters neutrophil function in dairy cows during the postpartum period.

description: Fibre-reinforced polymers (FRPs) are characterised by an anisotropic behaviour, with high tensile strength in the longitudinal direction but being very sensitive to transverse pressure. Traditional rein-forcement principles for steel-reinforced structures that aim at an ease of handling rather than to align the reinforcement according to the principal stresses thus result in a low utilisation rate if trans-ferred one by one to FRP-reinforced structures. New manufacturing methods for FRP textile rein-forcements, however, allow to overcome these shortcomings. In this paper, we explore the potential of embroidery technology to produce a stress-aligned FRP textile reinforcement for a simply sup-ported beam loaded by a single load in midspan (three-point bending test). The beam itself is shape-optimised to minimise cement consumption, making the geometry more complex and thus challeng-ing to reinforce. The optimum reinforcement design was found by linear elastic analysis of the beam and automatically manufactured according to the CAD file derived from the principal stresses. While only two-dimensional reinforcement can usually be produced with embroidery technology, a three-dimensional reinforcement cage can be created by folding the reinforcement prior to the impregna-tion process. The following tests on beams reinforced with such stress-aligned textiles showed very promising results. Compared to a conventional orthogonal reinforcement pattern, the failure load was more than twofold because the crack opening of the governing shear crack, which led to failure in the reference beam, could be limited with the stress-aligned reinforcement.

description: We investigate the spectral shape, the anisotropy of the wave vector distributions and the anisotropy of the amplitudes of the magnetic fluctuations in the Earth's magnetosheath within a broad range of frequencies. We present the first observations of a Kolmogorov-like inertial range of Alfvenic fluctuations in the magnetosheath flanks, below fci. In the vicinity of fci, a spectral break is observed, like in solar wind turbulence. Above the break, the energy of compressive and Alfvenic fluctuations generally follow a power law with a spectral index between -3 and -2. Concerning the anisotropy of the wave vector distribution, we observe a change in its nature in the vicinity of ion characteristic scales: if at MHD scales there is no evidence for a dominance of a slab (k||>kperp) or 2D (kperp>k||) turbulence, above the spectral break, (f>fci, kc/wpi>1) the 2D turbulence dominates. This 2D turbulence is observed in six selected one-hour intervals among which the average proton beta varies from 0.8 to 9. It is observed for both the transverse and compressive magnetic fluctuations, independently on the presence of linearly unstable modes at low frequencies or Alfven vortices at the spectral break. We then analyse the anisotropy of the magnetic fluctuations in a time dependent reference frame based on the field B and the flow velocity V directions. Within the range of the 2D turbulence, at scales [1,30]kc/wpi, and for any beta we find that the magnetic fluctuations at a given frequency in the plane perpendicular to B have more energy along the BxV direction. This non-gyrotropy of the fluctuations is consistent with gyrotropic fluctuations at a given wave vector, with kperp>k||, which suffer a different Doppler shift along and perpendicular to V in the plane perpendicular to B.

description: Even if the anatomical cardiac axis is not identical to its electrical axis, it is well known that in various species, the cardiac morphological changes are reflected on the angle of electrical cardiac axis. In this way, it has been shown in man (1, 2), dog (3, 4) and horse (5, 6), that cardiac vectors amplitude and orientation are modified by growth, training or pathological ventricular hypertrophy induced by various cardiac disorders including right and left valvulopathy, hindrances in systemic blood circulation accompanying extracardial diseases and hypertension in pulmonary circulation. By contrast, in the bovine species, electrocardiography consisted up to now in a purely qualitative analysis of the cardiac electrical activity, whereas vectocardiographic studies were still lacking in this species. It was thus of great interest to perfect a vectocardiography technique for cattle. On the other hand, in ungulae, depolarisation pattern of the heart is specific because of a particular organisation of the Purkinje fibers in the myocardium (7). Accordingly, several specific lead systems have been developed in the horse to quantify tridimensional vectocardiographic parameters. Because of the similarities between cardiac electric activity and between heart position within the thorax in horse and cattle (7), the validity of four of these equine lead systems was compared when transposed in calves.

description: We consider the secular dynamics of a binary and a planet in terms of non-restricted, hierarchical three-body problem, including the general relativity corrections to the Newtonian gravity. We determine regions in the parameter space where the relativistic corrections may be important for the long-term dynamics. We try to constrain the inclinations of putative Jovian planets in recently announced binary systems of HD 4113 and HD 156846.

description: Bovine respiratory disease is the most common disease associated with recently transported cattle in North American feedlots. Retrospective data collected in 1984 from commercial feedlots in Texas indicate that 83% of total morbidity and 66% of total mortality was attributable to respiratory disease1. A review of feedlot data from Kansas and Nebraska in 1987 reported similar results with 79% of total morbidity and 67% of total mortality attributed to respiratory disease2. Danofloxacin* is a novel, potent third generation fluoroquinolone which has bactericidal activity against a broad spectrum of bacteria and mycoplasmas of veterinary importance. Minimum inhibitory concentrations expressed as MIC 90' s of danofloxacin to a large sampling of common bovine respiratory pathogens Pasteurella haemolytica, P. multocida and Haemophilus sommus have been reported at 0.25, 0.125 and 0.25 μg/ml, respectively3. This trial was conducted to confirm the therapeutic efficacy of danofloxacin in the treatment of naturally occurring bovine respiratory disease in a research feedlot facility in Texas which maintains management practices typical for the commercial feedlots in the area. Efficacy was assessed based on the reduction in pyrexia, improvement in clinical condition, reduction in number of response failures, prevention of mortality, and the maintenance of normal weight gain.

open data benchmark dataset guidelines

description: This paper presents a structured approach to creating benchmark datasets and proposes guidelines for open-data sharing in the field of cartographic user research using neuroscientific methods including but not limited to eye tracking, EEG, and fMRI. The unique complexities introduced by geospatial data and maps make geospatial tasks fundamentally different from those encountered in the experimental psychology or cognitive visualization domains. We argue that datasets capable of addressing specific cartographic problems possess significant value and hold the potential to become benchmarks. For instance, studying the cognitive load and strategies employed by map users during various map tasks can provide valuable insights for map design and serve as benchmarks in developing complexity algorithms for cartography. We emphasize that benchmarks should be tailored to specific scientific issues rather than solely focusing on data standards. Such benchmarks not only contribute to map usability research but also play a pivotal role in developing predictive models that consider the visual attention and map use capabilities of users. Researchers across domains bear the responsibility of actively seeking concrete methods to encourage the open sharing of experimental data, complemented by high-quality metadata. By fostering the creation of benchmark datasets and promoting open-data sharing, collaboration is enhanced, cartographic research advances, and the scientific community is empowered to effectively address cartographic challenges.

description: We investigate the origin of the prompt and delayed emission observed in the short GRB 090510. We use the broad-band data to test whether the most popular theoretical models for gamma-ray burst emission can accommodate the observations for this burst. We first attempt to explain the soft-to-hard spectral evolution associated with the delayed onset of a GeV tail with the hypothesis that the prompt burst and the high energy tail both originate from a single process, namely synchrotron emission from internal shocks. Considerations on the compactness of the source imply that the high-energy tail should be produced in a late-emitted shell, characterized by a Lorentz factor greater than the one generating the prompt burst. However, in this hypothesis, the predicted evolution of the synchrotron peak frequency does not agree with the observed soft-to-hard evolution. Given the difficulties of a single-mechanism hypothesis, we test two alternative double-component scenarios. In the first, the prompt burst is explained as synchrotron radiation from internal shocks, and the high energy emission (up to about 1 s following the trigger) as internal shock synchrotron-self-Compton. In the second scenario, in view of its long duration (\sim 100 s), the high energy tail is decoupled from the prompt burst and has an external shock origin. In this case, we show that a reasonable choice of parameters does indeed exist to accommodate the optical-to-GeV data, provided the Lorentz factor of the shocked shell is sufficiently high. Finally, we attempt to explain the chromatic break observed around \sim 1e3 s with a structured jet model. We find that this might be a viable explanation, and that it lowers the high value of the burst energy derived assuming isotropy, \sim 1e53 erg, below \sim 1e49 erg, more compatible with the energetics from a binary merger progenitor.

description: Dieser Beitrag definiert Transformation als einen evolutionären, langfristigen, aber auch disruptiven Prozess, der hier und jetzt gestaltet werden kann. Wir unterscheiden zwischen einer deskriptiven und einer normativen Bedeutung von Transformation, d. h. zwischen derzeit stattfindenden Umbrüchen (Istzustand) und zielgerichteten, grundlegenden Veränderungen von Rahmenbedingungen (Sollzustand). Darauf aufbauend entwickeln wir das Konzept der transformativen Innovation: Im Sinne evolutionär-transformativer Prozesse verbindet es erstens kurzfristige und pragmatische Schritte mit einem langfristig radikalen Zielhorizont; es betont zweitens, dass das zielgerichtete Gestalten von Rahmenbedingungen in einer immer schon vor-strukturierten Welt stattfindet und daher den Istzustand berücksichtigen muss; es impliziert drittens gleichzeitige Prozesse der Innovation und Exnovation, der Neuerung und Beendigung, politische Entscheidungen für und gegen bestimmte Praktiken. Nach der Skizze eines konkreten Beispiels einer transformativen Innovation in der Stadtentwicklung folgen Überlegungen zu neuen Formen der Entscheidungsfindung und Kooperation, um transformative Innovationen zu verwirklichen.
Compressing the hidden variable space of a qubit

description: In previously exhibited hidden variable models of quantum state preparation and measurement, the number of continuous hidden variables describing the actual state of a single realization is never smaller than the quantum state manifold dimension. We introduce a simple model for a qubit whose hidden variable space is one-dimensional, i.e., smaller than the two-dimensional Bloch sphere. The hidden variable probability distributions associated with the quantum states satisfy reasonable criteria of regularity. Possible generalizations of this shrinking to a N-dimensional Hilbert space are discussed.

description: Unlike gas-phase reactions, chemical reactions taking place on interstellar dust grain surfaces cannot always be modeled by rate equations. Due to the small grain sizes and low flux,these reactions may exhibit large fluctuations and thus require stochastic methods such as the moment equations. We evaluate the formation rates of H2, HD and D2 molecules on dust grain surfaces and their abundances in the gas phase under interstellar conditions. We incorporate the moment equations into the Meudon PDR code and compare the results with those obtained from the rate equations. We find that within the experimental constraints on the energy barriers for diffusion and desorption and for the density of adsorption sites on the grain surface, H2, HD and D2 molecules can be formed efficiently on dust grains. Under a broad range of conditions, the moment equation results coincide with those obtained from the rate equations. However, in a range of relatively high grain temperatures, there are significant deviations. In this range, the rate equations fail while the moment equations provide accurate results. The incorporation of the moment equations into the PDR code can be extended to other reactions taking place on grain surfaces.
