description: This letter presents an extension of EPL116(2017)62001 to light- and strange-quark nonequilibrium chemical phase-space occupancy factors ($γ_{q,s}$). The resulting damped trigonometric functionalities relating $γ_{q,s}$ to the nucleon-nucleon center-of-mass energies $(\sqrt{s_{NN}})$ looks very similar except different coefficients. The phenomenology of the resulting $γ_{q,s}(\sqrt{s_{NN}})$ describes a rapid decrease at $\sqrt{s_{NN}}\lesssim7~$GeV followed by a faster increase up to $\sim20~$GeV. Then, both $γ_{q,s}$ become nonsensitive to $\sqrt{s_{NN}}$. Although these differ from $γ_{s}(\sqrt{s_{NN}})$ obtained at $γ_q(\sqrt{s_{NN}})=1$, various particle ratios including $\mathrm{K}^+/π^+$, $\mathrm{K}^-/π^-$, $\mathrmΛ/π^-$, $\bar{\mathrmΛ}/π^-$, $\mathrmΞ^+/π^+$, and $\mathrmΩ/π^-$, can well be reproduced, as well. We conclude that $γ_{q,s}(\sqrt{s_{NN}})$ should be instead determined from fits of various particle yields and ratios but not merely from fits to the particle ratio $\mathrm{K}^+/π^+$.

description: No abstracts are to be cited without prior reference to the author.Gadget is a statistical modelling framework which can be used to create multispecies, multifleet, multiarea models. The development of a complex multispecies model requires understanding of the modelled single species population. Simple single species models also are essen- tial in evaluating whether more complex models increase understand- ing of the population dynamics. In this paper, Gadget is illustrated using a single species case study with two stock components on one area. Features of the implementation include immature and mature stock components, maturation, predation of the immature stock com- ponent and two fleets. Parameter estimation is done using maximum likelihood based on a variety of datasets. The estimated parameters relate to growth, maturation, fleet selection, recruitment, the initial population and consumption. Likelihood data include survey indices, biological samples from the catch and survey and stomach data. Op- timisation of the model, along with a protocol to estimate appropriate weighting of the likelihood components are described. The effect of reduced data availability on parameter estimation is also considered by excluding age data from the likelihood components.'

description: We establish a set-oriented algorithm for the numerical approximation of the rotation set of homeomorphisms of the two-torus homotopic to the identity. A theoretical background is given by the concept of ε-rotation sets. These are obtained by replacing orbits with ε-pseudo-orbits in the definition of the Misiurewicz-Ziemian rotation set and are shown to converge to the latter as ε decreases to zero. Based on this result, we prove the convergence of the numerical approximations as precision and iteration time tend to infinity. Further, we provide analytic error estimates for the algorithm under an additional boundedness assumption, which is known to hold in many relevant cases and in particular for non-empty interior rotation sets.

description: Cattle are the reservoir for E. coli O157:H7 which is a contaminant of beef products and has been associated with food-borne illnesses in humans. Recently an E. coli O157:H7 SRP® vaccine extract received conditional licensure in the United States for the control of E. coli 0157 in cattle. Cattle are believed to become colonized with E. coli 0157 around the time of birth. The majority of existing research and control strategies attempt to control E.coli 0157 at the feedyard and harvest stages of production. These approaches are addressing the problem post-colonization. The objective of this study was to determine the shedding characteristics and performance of E. coli O157:H7 SRP-vaccinated beef calves born to E. coli O157:H7 SRP-vaccinated dams.

description: Reconfiguration paths express sequences of successive reconfiguration operations within a component-based approach allowing dynamic reconfigurations. We use constructs from regular expressions-pin particular, alternatives-to introduce multiple reconfiguration paths. We show how to put into action procedures allowing architectural, event, and temporal properties to be proved. Our method, related to finite state automata and using marking techniques, generalises what we did within previous work, where the regular expressions we processed were more restricted. But we can only deal with a subset of first-order logic formulas.

description: Bovine tuberculosis (bTB), caused by the zoonotic agent Mycobacterium bovis, is a significant threat to Michigan livestock and wildlife. After the state was declared free of bTB in 1979, the disease re-emerged in wild white-tailed deer in 1994 and in cattle in 1998. The Michigan Bovine Tuberculosis Eradication Project was established in 1995. Partners in the project are the Michigan Department of Agriculture (MDA), Michigan Department of Natural Resources and Environment (MDNRE), USDA APHIS Veterinary Service, Michigan Department of Community Health, and Michigan State University. Tens of millions of dollars have been spent on the project. In cattle alone, $5.2 million is spent on herd testing annually. After 15 years of the project's eradication efforts, bTB remains a challenge. The purpose of this study was to conduct a descriptive epidemiological review of bTB in Michigan and to identify any information that may be useful in moving the project forward.

description: The stems of Dendrobium huoshanense have long been used to prevent various diseases, including inflammatory diseases. This study was aimed to explain the anti-inflammatory effect of D. huoshanense stems in LPS-induced RAW 264.7 macrophages and to discover potential anti-inflammatory compounds. Results exhibited that D. huoshanense stems ethanol extract could significantly inhibit LPS-induced production of NO, TNF-α and IL-1β. Based on bioassay guided strategy, four bibenzyls (1–4) were isolated from D. huoshanense stems for the first time. Anti-inflammatory assay showed 1–4 could remarkably inhibit the production of NO in LPS-induced macrophages. Moreover, quantitative RT-PCR analysis displayed that the mRNA levels of iNOs, TNF-α and IL-1β could also be significantly reduced by 1–4. These results suggested that D. huoshanense stems ethanol extract and bibenzyls 1–4 might be well developed as therapeutic agent to prevent inflammatory diseases.
Efficacy of gonadorelin hydrochloride or gonadorelin diacetate tetrahydrate 7 days after Al in field conditions to boost progesterone levels, a randomized clinical trial

description: The ability of some reproduction synchronization protocols to increase conception rates (CR) is reported as being in part due to increased progesterone (P4) levels in the diestrus phase before breeding. This has been demonstrated mostly in an experimental context and was linked to GnRH increasing the proportion of cows luteinizing a second corpus luteum (CL). A pilottrial was conducted to determine if an injection of gonadorelin hydrochloride (Factrel®) or gonadorelin diacetate tetrahydrate (Cystorelin®) given 7 days after AI to all cows on a farm in field conditions resulted in a significant increase of P4 levels 14 days after AI, compared to a placebo. If an increase in P4 levels was to be observed, a second larger trial was to be conducted testing the effect of post-AI GnRH on CR at return to estrus.

description: Complex oxides exhibit many intriguing phenomena, including metal-insulator transition, ferroelectricity/multiferroicity, colossal magnetoresistance and high transition temperature superconductivity. Advances in epitaxial thin film growth techniques enable us to combine different complex oxides with atomic precision and form an oxide heterostructure. Recent theoretical and experimental work has shown that charge transfer across oxide interfaces generally occurs and leads to a great diversity of emergent interfacial properties which are not exhibited by bulk constituents. In this report, we review mechanisms and physical consequence of charge transfer across interfaces in oxide heterostructures. Both theoretical proposals and experimental measurements of various oxide heterostructures are discussed and compared. We also review the theoretical methods that are used to calculate charge transfer across oxide interfaces and discuss the success and challenges in theory. Finally, we present a summary and perspectives for future research.

Medical error

description: Medical error is an emerging issue, brought to the public’s attention abruptly in 2000 by the National Institute of Medicine's To Err is Human report. Because human error is at its root, medical error is a complex and sensitive topic, is likely underreported, often requires process change to reduce, and is difficult to prevent. With the occurrence of at least a minimum level of human error now being regarded as inevitable, using lessons from high reliability organizations functioning in fault-intolerant industries, such as commercial aviation and nuclear power, the reduction of medical error is shifting from a focus on individual failings to a focus on the system in which it is occurring. This paper reviews the definitions of medical error, summarizes its frequency primarily in the diagnostic aspect of human and veterinary medicine, touches briefly upon approaches to reducing it, and provides references, many online, for pursuing the topic further.

Effects of production practices on Mannheimia haemolytica
Creators: name: Woolums, Amelia R.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 2017

description: Mannheimia haemolytica is a leading contributor to bovine respiratory disease (BRD). Various vaccines are available for prevention or control of BRD due to M. haemolytica; published research indicates that vaccines can decrease BRD morbidity. Several antimicrobials are labeled for treatment or control of BRD due to M. haemolytica. Historically, metaphylaxis (mass antimicrobial medication at arrival) has been shown to reliably decrease BRD morbidity in highrisk cattle. Until recently, antimicrobial resistance (AMR) in M. haemolytica has been rare, even in cattle given antimicrobials. However, in the past 5 years multiple reports described M. haemolytica isolates from fatal BRD cases that are resistant to many or most antimicrobials. Additionally, nasopharyngeal shedding of AMR M. haemolytica by large proportions of live high-risk cattle following metaphylaxis has been reported. This information suggests that response rates following antimicrobial administration for BRD treatment or control may begin to decline. However, to date, reported death rates have not been high in cattle described to be shedding AMR M. haemolytica, and retrospective studies have not revealed a direct relationship between prevalence of AMR M. haemolytica and treatment failure. Properly designed prospective studies are needed to more clearly define the impact of AMR M. haemolytica in cattle populations.

Facts and fiction regarding anthelmintic efficacies in cattle
Creators: name: Yazwinski, T. A.

name: Jones, L.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference

description: Very few label claims for cattle anthelmintic efficacies are factual under all circumstances. This is because: 1) no new class of anthelmintic has been commercialized in the USA since the mid 1980s; 2) worm populations are forced into selection for resistance every time a bovine is treated; 3) some resistant female worms can void >2000 eggs per day; and 4) rarely are anthelmintics given at the farm level wherein sustainable effectiveness is safeguarded. Given the above, it is not shocking that most label claims of effectiveness and persistence for ALL anthelmintics (endectocides, flukicides, and nematocides) are currently overstated. Lack of excellent nematocidal efficacies has been either accepted as normal or overlooked by cattle people, a state of affairs made possible by the fact that bovine nematodiasis is largely a subclinical condition. Lack of anthelmintic efficacy is not connected to suboptimal animal performance. Routinely, there is no "real world” quantification ofthe detriment caused by post-treatment worm burdens; an observation primarily reserved for research projects. The efficiency of the cattle industry (beef and dairy) and the per-animal productivity in the US have been on a steady rise for decades, due in large part to advances in nutrition, genetics, husbandry, and disease control. Unfortunately, the trend in effective chemical control for parasites over the same period has been in the opposite direction. Advances are sorely needed in both chemical and non-chemical (husbandry, vaccine, biological, nutriceutical, genetic) parasite controls. In this paper, a few observations will be made on anthelmintic efficacies, and the impact of ineffective nematocidal control.

description: No abstracts are to be cited without prior reference to the author.Results from the Icelandic groundfish survey show that all age groups of haddock are much more available to the survey than corresponding age groups of most other species and at age 2 haddock is close to fully recruited to the survey. High catchability of small haddock in the groundfish survey combined with the common perception that small haddock is relatively sensitive to handling could indicate that hidden mortality caused by the fisheries may be a relatively large problem. Discard analysis comparing length measurements from landings and from inspectors aboard the fishing vessels indicate that discard of undersized haddock is considerable in the haddock fishery and proportionally larger than for example in the cod fishery. In recent years, most haddock yearclasses have been large and those yearclasses have become progressively larger in every new survey, indicating possible reduction in mortality compared to earlier years. The spatial distribution of those yearclasses compared with previous ones, is such that larger proportion inhabits the waters north of Iceland where fishing effort has been small in this period In this paper the spatial distribution of the commercial fishing effort and the spatial distribution of haddock in the groundfish survey in March are matched and an index of the number of haddock ’’filtered’’ by the fisheries is calculated, based on the fishing effort and overlap of the spatial distribution of the fisheries and the haddock. The index of filtering is then used in a catch at age model as a measure of hidden mortality. Results confirm that hidden mortality caused by the fisheries could be important for the dynamics of this stock and explain some of the discrepancies seen in survey indices in recent years.
Nine months in with the veterinary feed directive

description: Last year at this time we were preparing for the Veterinary Feed Directive (VFD) transition and now we are survivors. There have been countless conversations between veterinarians and clients related to label indications, extralabel use, durations of use, concurrent use, repeated regimens (pulses), "hand fed” vs approved free choice feeds, and what comes next. We have advanced to the point of at least clarifying the uncertainties related to these subjects, and there is an indication of the next regulatory focus related to in-feed drugs. The "Blue Bird" labels have become familiar to many veterinarians to clarify the legal inclusions of Type C feeds. Also, Compliance Policy guide 615.115 has been useful for understanding the ability to use in-feed drugs in an extralabel manner in minor species. It is now clearly understood that asecond administration of an approved in-feed drug regimen to an animal requires an additional VFD be written. For determining which drugs may be concurrently fed together in feed, the Blue Bird labels and the Feed Additive Compendium are key sources. Next in the regulatory lineup is an evaluation of medically important in-feed antibiotics for which there is not a defined duration of administration in the label regimen.

The first one, in particular cases, allows the estimation of the orbital period of binary lenses, which in turn enables the breaking of degeneracies. The second one is a method to measure the rotation period of the lensed star by observing signatures due to stellar spots on its surface.

description: A key challenge in System of Systems (SoS) engineering is the analysis and maintenance of global properties under SoS evolution, and the integration of new constituent elements. There is a need to model the constituent systems composing a SoS in order to allow the analysis of emergent behaviours at the SoS boundary. The Contract pattern allows the engineer to specify constrained behaviours to which constituent systems are required to conform in order to be a part of the SoS. However, the Contract pattern faces some limitations in terms of its accessibility and suitability for verifying contract compatibility. To address these deficiencies, we propose the enrichment of the Contract pattern, which hitherto has been defined using SysML and the COMPASS Modelling Language (CML), by utilising SysML and Object Constraint Language (OCL). In addition, we examine the potential of interface automata, a notation for improving loose coupling between interfaces of constituent systems defined according to the contract, as a means of enabling the verification of contract compatibility. The approach is demonstrated using a case study in audio/video content streaming.

description: We start with the Hamiltonian formulation of the first order action of pure gravity with a full $\mathfrak{sl}(2,\mathbb C)$ internal gauge symmetry. We make a partial gauge-fixing which reduces $\mathfrak{sl}(2,\mathbb C)$ to its sub-algebra $\mathfrak{su}(1,1)$. This case corresponds to a splitting of the space-time ${\cal M}=Σ\times \mathbb R$ where $Σ$ inherits an arbitrary Lorentzian metric of signature $(-,+,+)$. Then, we find a parametrization of the phase space in terms of an $\mathfrak{su}(1,1)$ commutative connection and its associated conjugate electric field. Following the techniques of Loop Quantum Gravity, we start the quantization of the theory and we consider the kinematical Hilbert space on a given fixed graph $Γ$ whose edges are colored with unitary representations of $\mathfrak{su}(1,1)$. We compute the spectrum of area operators acting of the kinematical Hilbert space: we show that space-like areas have discrete spectra, in agreement with usual $\mathfrak{su}(2)$ Loop Quantum Gravity, whereas time-like areas have continuous spectra. We conclude on the possibility to make use of this formulation of gravity to construct a holographic description of black holes in the framework of Loop Quantum Gravity.

description: No abstracts are to be cited without prior reference to the author.The conditional probability density for the location of fish can be modelled by Kolmogorov’s forward equation. The parameters of such a model are estimated from Cod tagging data around Iceland during the period from 1993 to 1997. The movement parameters in the Kolmogorov model are advection - velocity and diffusion parameters. These parameters are estimated based on compartmental divisions around Iceland and on the given time divisions. Three time intervals are considered within each year: spawning migration from January 1 until April 30, spawning from May 1 until May 31 and feeding migration from June 1 until December 31. The maximum likelihood function is the main tool in parameter estimation. The likelihood function is calculated from the probability density function, which is obtained from the Kolmogorov’s model. Keywords: fish migration, advection-diffusion equation, cod, parameter estimation.

description: The spread of antibiotic resistance genes (ARGs) has become a global environmental issue; it has been found that nanoparticles (NPs) can promote the transfer of ARGs between bacteria. However, it remains unclear whether NPs can affect this kind of conjugation in Streptomyces, which mainly conjugate with other bacteria via spores. In the present study, we demonstrated that Al2O3 NPs significantly promote the conjugative transfer of ARGs from Escherichia coli (E. coli) ET12567 to Streptomyces coelicolor (S. coelicolor) M145 without the use of heat shock method. The number of transconjugants induced by Al2O3 particles was associated with the size and concentration of Al2O3 particles, exposure time, and the ratio of E. coli and spores. When nanoparticle size was 30 nm at a concentration of 10 mg/L, the conjugation efficiency reached a peak value of 182 cfu/108 spores, which was more than 60-fold higher than that of the control. Compared with nanomaterials, bulk particles exhibited no significant effect on conjugation efficiency. We also explored the mechanisms by which NPs promote conjugative transfer. After the addition of NPs, the intracellular ROS content increased and the expression of the classical porin gene ompC was stimulated. In addition, ROS enhanced the mRNA expression levels of conjugative genes by inhibiting global regulation genes. Meanwhile, expression of the conjugation-related gene intA was also stimulated, ultimately increasing the number of transconjugants. Our results indicated that Al2O3 NPs significantly promoted the conjugative transfer of ARGs from bacteria to spores and aggravated the diffusion of resistance genes in the environment.
Role of the microbiome in respiratory disease

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 2017

description: "Microbiome” is a term used to describe the community of microorganisms that live on and within vertebrate hosts. These microorganisms primarily live in the gastrointestinal tract and play an important role in nutrient digestion and development of immunity. Understanding the role of the gut microbiome in health and disease is a new and exciting field of study. For decades, the focus on managing infectious disease has been on the pathogen(s) of interest, virtually ignoring the role of beneficial microbes in potentiating or eliminating disease. In addition, initial research evaluating the role of the microbiome in disease was centered on enteric pathogens, due to the inherent proximity of pathogenic and nonpathogenic microorganisms in the digestive tract. However, recent investigations have revealed the potential role of the microbiome in diseases outside the gastrointestinal tract, such as neurologic, respiratory, and autoimmune diseases. Considering the role of the microbiome in clinical disease and decreased performance associated with respiratory infections, this area of research becomes even more relevant to food animal production. The objective of this paper is to review associations between the gut microbiome and outcome during infectious respiratory disease in animals.

description: Presolar grains are small particles found in meteorites through their isotopic compositions which are considerably different from those of materials in the Solar System. If some isotopes in presolar grains diffused out beyond their grain sizes when they were embedded in parent bodies of meteorites, their isotopic compositions could be washed out, and hence the grains cannot be identified as presolar grains any more. We explore this possibility for the first time by self-consistently simulating the thermal evolution of planetesimals and the diffusion length of $^{18}$O in presolar silicate grains. Our results show that presolar silicate grains smaller than $\sim$ 0.03 $μm$ cannot keep their original isotopic compositions even if the host planetesimals experienced maximum temperature as low as 600 $^{\circ}$C. Since this temperature corresponds to the one experienced by petrologic type 3 chondrites, the isotopic diffusion can constrain the size of presolar silicate grains discovered in such chondrites to be larger than $\sim$ 0.03 $μm$. We also find that the diffusion lengths of $^{18}$O reach $\sim$ 0.3-2 $μm$ in planetesimals that were heated up to 700-800 $^{\circ}$C. This indicates that, if the original size of presolar grains spans a range from $\sim$ 0.001 $μm$ to $\sim$ 0.3 $μm$ like that in the interstellar medium, the isotopic records of the presolar grains may be almost completely lost in such highly thermalized parent bodies. We propose that isotopic diffusion could be a key process to control the size distribution and abundance of presolar grains in some types of chondrites.

description: The sheer size and structure of livestock operations in the United States, combined with extensive movement between production phases, presents unprecedented foot and mouth disease [FMD) control challenges. The economic impact of an outbreak would be immediate and harsh. The goal of FMD response is to control and eradicate FMD while preserving the US livestock industry, a delicate and precarious balance of priorities. Bovine veterinarians have an opportunity and responsibility to help their clients prepare for a potential FMD outbreak. The voluntary Secure Milk and Secure Beef Supply Plans give veterinarians the tools they need to help their clients implement key business continuity strategies. The biosecurity mitigations and surveillance capabilities will be essential to protect animal health, decrease disease spread, and allow some semblance of business continuity for the livestock industry.

description: Anaplasmosis, caused by the rickettsial hemoparasite Anaplasma marginale (Am), is the most prevalent tick-transmitted disease of cattle worldwide and a major obstacle to profitable beef production in the continental United States (US). Anaplasmosis is readily transmitted through biological and mechanical vectors, such as ticks and biting flies, and iatrogenically through needles and equipment contaminated with infected blood. Clinical anaplasmosis, characterized by anemia, icterus and fever, is associated with significant production losses, abortions, and mortalities in cattle. It is estimated that the introduction of anaplasmosis into a previously naive herd can result in a 3.6% reduction in calf crop, a 30% increase in cull rate, and a 30% mortality rate in clinically infected adult cattle. Furthermore, a study has shown that 16% of pregnant carrier cows will transmit anaplasmosis in utero producing persistently infected offspring. The existence of both horizontal and vertical anaplasmosis transmission has important implications for disease control in endemic areas. The cost of a clinical case of anaplasmosis in the US has been conservatively estimated at more than $400 per animal, with some estimating the total cost to the beef industry at more than $300 million per year.

description: No abstracts are to be cited without prior reference to the author.The scope of this paper is to identify, for a wide selection of fleets, fisheries and stocks, the elements of fishing effort that can be attributed to fishing tactics and strategies, and to evaluate the benefits of using adjusted definitions of fishing effort. Indices have been derived to reflect shifts in tactics (within a trip) and in strategies (within a year). The Shannon-Wiener spatial diversity indices of tactics (FT_SW) and strategies (YE_SW) had the greatest impact on catch rates. In particular, FT_SW was negatively correlated to the catch rates of each combination of fleets and species investigated. One may anticipate that during a fishing trip, vessels with high FT_SW have been searching fish aggregations for a long time, while vessels with low FT_SW have been more efficient in finding these aggregations. YE_SW was negatively correlated to the catch rates for most of the combinations of fleets and species investigated. The fishing locations of traditional species are fairly well known by fishermen, and there is little benefit exploring new fishing grounds. This reasoning however does not apply when fishermen harvest species such as roundnose grenadier, for which new aggregations are still being discovered. For the French vessels, a broad distribution of fishing effort may be an appropriate strategy to promote the capture of roundnose grenadier. Adjusting fishing effort generally lead to a gain in the precision of the relationship between fishing mortality and fishing effort. Nevertheless, the coefficient of determination of the regression between log-transformed partial fishing mortality and adjusted fishing effort never exceeded 40%. This indicates that this study goes one step towards the right direction, but also that more research is needed to carry on the development of a reliable fishing effort model.

description: Magnetic nanoparticles constitute potential nanomedicine tools based on the possibility to obtain different responses triggered by safe remote stimulus. However, such richness can be detrimental if the different performances are not accurately differentiated (and controlled). An example of this is the reorientation of magnetic nanoparticles under the influence of AC fields, which can be exploited for either magneto-mechanical actuation (MMA) at low frequencies (tens of Hz); or heat release at large ones (MHz range). While it is clear that Brownian rotation is responsible for MMA, its heating role in the high-frequency regime is not clear. In this work we aim to shed light on this issue, which needs to be well understood for applications in magnetic fluid hyperthermia (MFH) or heat triggered drug release. Using a Brownian dynamics (BD) simulation technique, we have theoretically investigated the contribution of Brownian reversal in disk-shape particles (to enhance the viscous interaction with the environment) over a wide range of frequencies. Our results predict essentially negligible hysteresis losses both in the high- and low-frequency domains, with completely different implications: highly efficient MMA, but negligible MFH performance. Importantly, complementary micromagnetic simulations indicate that the large magnetic torque assumption of the BD simulations is supported by hexagonal-shape disks, up to field amplitudes of the order of 100 Oe. Larger fields would lead to Néel reversal which, noteworthy, predicts significant heating performance. The possibility of switching between the MMA and MFH response by changing the amplitude of the AC field, together with their distinct optimal conditions (large magnetic torque for MMF; large heating for MFH), points to such hexagonal nanodisks as promising nanomedicine agents with double mechanical and heating functionalities.

description: In this paper, simultaneous removal of methylene blue (MB) and Pb2+ from the binary component system by an easily prepared cross-linked lignosulfonate bio-adsorbent (CLLS) was described. CLLS was characterized by FTIR, SEM/EDS and TGA. The influences of pH, temperature, contact time and initial MB and Pb2+ concentrations on the adsorption performance were investigated. The results demonstrated a good ability of CLLS to remove MB and Pb2+ simultaneously. Using of 1.0 g L−1 loading, removal efficiency of MB and Pb2+ reached 98.0% and 97.8%, respectively, in the MB (100 mg.L−1)-Pb2+ (50 mg.L−1) system. Moreover, the adsorption isotherms and adsorption kinetics indicated that the results were fitting well with the Langmuir and pseudo-second-order model, respectively, for both MB and Pb2+. Based on the Langmuir model, the maximum adsorption capacity of MB and Pb2+ reached 132.6 and 64.9 mg g−1, respectively, in the MB-Pb2+ system, which was much lower than that in the single component system (358.4 mg g−1 100.9 mg g−1 for MB and Pb2+, respectively). Hence, simultaneous adsorption of MB and Pb2+ onto CLLS was an antagonistic adsorption. In addition, an apart-sequential adsorption method was used to study the action of adsorption sites on CLLS for MB and/or Pb2+ with the help of an efficient self-made apparatus. Rudimental results showed that there would be three different kinds of adsorption sites on CLLS: MB-site, Pb2+-site and MB/Pb2+- shared sites. Furthermore, in the MB (100 mg.L−1)-Pb2+(50.0 mg.L−1) system, the simultaneous removal efficiency of MB and Pb2+ still maintained 91.8% and 85.0%, respectively, after 6 cycles.

description: No abstracts are to be cited without prior reference to the author.With the use of multispecies models of marine stocks and recognition of spatial differences in spatial overlap, migration rates play an increasingly important role. Further, traditional estimates of growth based on samples from fishing gear are confounded with the selection pattern in an obvious way, excacerbated when multispecies issues are considered. For these and other reasons there is a need to explicitly include tagging data as a component of fisheries models. A statistical multispecies multi-area framework has been extended to predict tag returns and subsequently incorporate tagging data in likelihood components, to be used when estimating migration rates. The information content of such data is not clear a priori but simulation experiments indicate that bootstrapped uncertainty estimates may be reasonable indicators.
