Mating systems in Xerula australis, Xerula furfuracea, Xerula incognita (sp.nov.), Xerula megalospora, Xerula rugosoceps, and the Xerula radicata complex are described, with notes on culture morphology and biogeographic distribution. All taxa tested were bifactorial (i.e., tetrapolar) and genetically isolated from one another. Multiple collections of X. furfuracea and X. megalospora were found to interbreed in vitro. Two collections of putative European X. radicata were found to be haploid, monokaryotic, nonmeiotic basidiomes genetically isolated from each other and from all other tested taxa, including X. radicata. Neohaploidization experiments with Xerula rufobrunnescens failed. A discussion comparing mating systems in Xerula to those in other genera of the Xerulaceae is included. Key words: mating systems, interbreeding, biological species, intersterility groups, biogeography, Xerula, basidiomycetes.

Population size and habitat disturbance are key factors likely to shape the mating system of populations in disturbed and fragmented landscapes. They would be expected to influence the availability and behaviour of the pollinator, the ability to find mates in self-incompatible species, inbreeding in self-compatible species and the size of the pollen pool. These in turn might be expected to influence key variables critical for population persistence such as seed production, seed germination and seedling fitness. Here we investigate mating-system variation in six rare species, i.e. Banksia cuneata, B. oligantha, Lambertia orbifolia (Proteaceae), Verticordia fimbrilepis subsp. fimbrilepis, Eucalyptus rameliana (Myrtaceae), Acacia sciophanes (Mimosaceae), and two common species, i.e. Calothamnus quadrifidus (Myrtaceae) and Acacia anfractuosa. All seven species are animal-pollinated relatively long-lived woody shrubs with mixed-mating systems. Population variation in mating-system parameters was investigated in relation to population size and habitat disturbance. We show that although the mating system will vary depending on pollination biology and life-history, as populations get smaller and habitat disturbance increases there is a trend towards increased inbreeding, smaller effective sizes of paternal pollen pools and greater variation in outcrossing among plants. From the species investigated in this study we have found that changes in the mating system can be useful indicators of population processes and can give valuable insight into the development of conservation strategies for the persistence of plant species following anthropogenic disturbance and landscape fragmentation.

Reproductive studies in invasive plants are necessary for an understanding of their potential to establish and spread in foreign environments. Elaeagnus umbellata Thunb. (autumn olive) is an invasive woody shrub that flowers early in the spring and is often noted for its abundant fruit set. This study examined the reproductive biology of E. umbellata in Illinois, where it is highly invasive. Hand-pollination experiments were performed to determine the breeding system of E. umbellata, and floral visitors were collected to determine its pollinators. Experiments showed that E. umbellata is a predominantly outcrossing species with a self-incompatible breeding system. However, individual variation was detected in several reproductive characteristics. Pollen tube analyses revealed that a small percentage of individuals allow successful self-pollen tube growth, and self-fruit set resulting from automatic self-pollination (autogamy) was relatively high in a few plants. Automatic self-pollination is possible because the male and female parts of flowers mature sychronously, but the likelihood of autogamy may vary among individuals due to variability in the spatial separation of male and female parts (herkogamy). Variability in the incompatibility system and the level of herkogamy may impact the outcrossing rates and reproductive success of individuals. The majority of floral visitors to E. umbellata were generalist pollinators. Frequently visiting bees included small and large species such as native Andrena spp., Augochlorella aurata, Bombus spp., Ceratina calcarata, Xylocopa virginica, and the introduced Apis mellifera. Bombylius major (large bee fly) and the moth Mythimna unipuncta (armyworm) were also frequent visitors. Most of the above insect taxa are pollinators of E. umbellata based on analysis of pollen on insect bodies. E. umbellata is likely to achieve its abundant fruit set where these common pollinators and other E. umbellata are present. However, in my study sites, many individuals experienced low fruit set on branches that were open to pollinator visitation, suggesting pollen limitation may be common in some years and at certain sites. The discovery of autogamous individuals demonstrates that some E. umbellata individuals may be able to establish and spread even when mates or pollinators are limiting.

Behavioral neurobiology aims at explaining behavior at the level of neurons and neuronal circuits, based on linking comparative anatomy, and the observation and manipulation of nervous system activity with animal behavior. The numerical simplicity and the presence of identified neurons in insect nervous systems make them outstanding model systems for neurobiology. The insect nervous system has a common ground plan with functionally specialized regions for sensory processing, integration, and motor control. In holometabolous species, the nervous system is restructured during metamorphosis to support new behavior. Different forms of plasticity allow for behavioral adaptations in the adult stage. Neuronal circuits for behavior in Drosophila melanogaster can be effectively analysed with genetic tools, as exemplified for courtship and mating behavior. Recent developments in connectomics and genome editing are expected to further behavioral neurobiology in a broad range of species and permit a comprehensive comparative approach to the neurobiology of behavioral ecology.

Genetic management of fragmented populations is one of the major, largely unaddressed issues in biodiversity conservation. Many species across the planet have fragmented distributions with small isolated populations that are potentially suffering from inbreeding and loss of genetic diversity (genetic erosion), leading to elevated extinction risk. Fortunately, genetic deterioration can usually be remedied by augmenting gene flow (crossing between populations within species), yet this is rarely done, in part because of fears that crossing may be harmful (but it is possible to predict when this will occur). Benefits and risks of genetic problems are sometimes altered in species with diverse mating systems and modes of inheritance. Adequate genetic management depends on appropriate delineation of species. We address management of gene flow between previously isolated populations and genetic management under global climate change.

The impact of bees on the world is immeasurable. Bees are responsible for the evolution of the vast array of brightly colored flowers and for engineering the niches of multitudes of plants, animals, and microbes. They’ve painted landscapes with flowers through their pollination activities and have evolved the most complex societies to aid their exploitation of the environment. The biology of the honey bee is one that reflects their role in transforming environments with their anatomical adaptations and a complex language that together function to exploit floral resources. A complex social system that includes a division of labor builds, defends, and provisions nests containing tens of thousands of individuals, only one of whom reproduces. Traditional biology texts present stratified layers of knowledge where the reader excavates levels of biological organization, each building on the last. This book presents fundamental biology not in layers but wrapped around interesting themes and concepts and in ways designed to explore and understand each concept. It examines the coevolution of bees and flowering plants, bees as engineers of the environment, the evolution of sociality, the honey bee as a superorganism and how it evolves, and the mating behavior of the queen.

A Primer of Population Genetics and Genomics, 4th edition, has been completely revised and updated to provide a concise but comprehensive introduction to the basic concepts of population genetics and genomics. Recent textbooks have tended to focus on such specialized topics as the coalescent, molecular evolution, human population genetics, or genomics. This primer bucks that trend by encouraging a broader familiarity with, and understanding of, population genetics and genomics as a whole. The overview ranges from mating systems through the causes of evolution, molecular population genetics, and the genomics of complex traits. Interwoven are discussions of ancient DNA, gene drive, landscape genetics, identifying risk factors for complex diseases, the genomics of adaptation and speciation, and other active areas of research. The principles are illuminated by numerous examples from a wide variety of animals, plants, microbes, and human populations. The approach also emphasizes learning by doing, which in this case means solving numerical or conceptual problems. The rationale behind this is that the use of concepts in problem-solving lead to deeper understanding and longer knowledge retention. This accessible, introductory textbook is aimed principally at students of various levels and abilities (from senior undergraduate to postgraduate) as well as practising scientists in the fields of population genetics, ecology, evolutionary biology, computational biology, bioinformatics, biostatistics, physics, and mathematics.

Children at the center of high conflict divorce and/or child protection cases face increased risks to both current and future health and adjustment. There is a growing research base regarding these risks and the coping abilities skills that children need for successful adjustment, but training gaps and poorly structured services continue to be serious problems. The specific characteristics of these families, and risks faced by these children, underscore the importance of treatment, psychoeducation, and other services adapted to this population and directed to minimizing risks and promoting healthy functioning, autonomy, and resilience for these children. This book provides a critical, research-informed analysis of the core factors to include when developing child-centered approaches to therapy and other family interventions, both in the formal treatment setting and promoting healthy engagement with the other systems and activities critical to children’s daily lives. The book addresses common problems, obstacles, and the backdrop of support from other professionals or the court, which may be necessary for successful intervention. An international team of renowned authors provide chapters covering a variety of service models and drawing on a wide range of relevant research and literature, addressing the legal context, central issues for treatment and other services, and specialized issues such as trauma, family violence, parent–child contact problems, and children with special needs. The book assembles in one place the best of what is known about intervention for court-involved families, along with practical guidance for using relevant research, understanding its limitations, and matching service plans to families’ needs.

The Queensland Geothermal Energy Centre of Excellence is investigating the use of supercritical CO2 closed loop Brayton cycles in the Concentrated Solar Thermal power cycle plant. One of the important components in the turbomachinery within the plant are seals. As the cycle is closed loop and operating at high pressures, dry gas seals have been recommended for future use in these systems. One of the main challenges of using supercritical CO2 dry gas seals is that operating conditions are near the critical point. In the supercritical region in the vicinity of the critical point (304 K, 7.4 MPa), CO2 behaves as a real-gas, exhibiting large and abrupt non-linear changes in fluid and transport properties and high densities. To correctly predict the seal operation and performance, the interaction between this real gas and the seal rotor (primary ring) and the seal stator (mating ring) need to analysed and investigated in detail, as they can lead to significant changes in flow and seal performance. Results from this paper show that increased centrifugal effects caused by higher gas densities can reduce the pressure in the sealing dam region. This adversely affects the loading capacity of the dry gas seal. However, it also benefits seal performances by reducing the leakage rate. The current work presents an investigation of the supercritical CO2 dry gas seals operating close to the critical point with an inlet pressure and temperature of 8.5Mpa and 370K respectively and a speed of 30000 RPM. Results highlighting the effects of the groove length or dam to groove ratio on the performance of the dry gas seal are presented. The seal is simulated using Computational Fluid Dynamics to study the flow behaviour of the supercitical CO2 in the dry gas seal. Supercritical CO2 fluid properties are based on the fluid database REFPROP. The numerical model was validated with previous work and good agreement was demonstrated.

Abstract The temperature of SCO2 fed to the boiler in SCO2 coal-fired power plants is relatively high, ∼500 °C. It leads to high boiler exhaust temperature, which is ∼120 °C according to previous studies. Waste heat recovery from low temperature fluegas in SCO2 coal-fired power plants is a key issue to be addressed to enhance power plant efficiency and electrostatic precipitator performance. Therefore, systems of waste heat recovery from low-temperature fluegas were proposed in this study. To evaluate the economic performances of the proposed systems and obtain the best system configurations, economic and thermodynamic models were developed. Moreover, multi-parameter optimization model based on Genetic Algorithm was developed. The waste heat recovery system is proposed and optimized by considering coupling and matching of the air preheating process, heat regenerative process and fluegas cooling process. With a 1000MW SCO2 coal-fired power plant as the reference case, thermodynamic and economic analyses were carried out. Results show that when the low temperature economizer is integrated together with the main compressor intercooling and flue bypass ahead the air-preheater, the temperature of exhaust fluegas can be decreased to ∼95 °C and the power plant efficiency can be enhanced by 1.39%-pts compared with basic system. Through the economic model analysis, the system levelized cost of electricity is 0.04158 $ kW−1 h−1.

Plane spiroid gears currently applied in feed motion rotary drives are roughly described in this paper. The theoretical possible methods of backlash adjustment in this kind of gear are mentioned. Referring to industry experience the only applied method, which uses the eccentric, is described. Its advantages as well as disadvantages related to operation and wearing process are pointed. The disadvantages are mainly connected with changing the gear axis distance while rotating eccentric in order to adjust backlash. A graph depicting the movements of the worm in the direction of backlash reducing and in the perpendicular one, which changes the axis distance, is given. In order to provide some information about the influence of changing axis distance on the mating of face toothing with the worm, mathematical model was created. Some effects of numerical calculations based on that model and showing the bearing contact of the face gear drive supplied with eccentric backlash adjustment are depicted. It can be noticed, how changing the axis distance influences the bearing contact. It can be also estimate if within the chosen range of eccentric rotation the theoretical bearing contact is still acceptable to operate correct. A simplified model presenting the wearing process is also provided. It reveals that after some operating time an edge contact appears while reducing backlash. It significantly decreases the operating time till the next adjustment. There are two methods of backlash reducing described: the first is typical whilst the second is improved and proposed by the author. The advantage of the proposed method is lengthening the operating time between two backlash adjustments. In the end a new type of spiroid gear mating with double-lead worm and deprived of aforesaid disadvantages is mentioned.

Animal breeding relies on two processes to achieve its objectives: the selection and the mating systems. Mating systems devise a particular plan to perform one or more breeding goals, which often encompass improving the herd's health and maximising financial gains in animal production systems. Compensatory mating is a strategy to produce animals with more homogeneous selection trait characteristics, discarding the production of exceptional animals in favour of a more balanced herd. This paper defines and investigates the complexity class of the optimal compensatory mating problem, proving that a polynomial-time algorithm can solve it.

A model of a Hybrid Power Plant (HPP) consisting of Compressed Air Energy Storage (CAES) coupled with a wind farm is presented. This kind of plant aims at overcoming some of the major limitations of wind-generated power plants, including low power density and an intermittent nature owing to variable weather conditions. In CAES, energy is stored in the form of compressed air in a reservoir during off-peak periods and used on demand during peak periods to generate power with a turbo-generator system. Such plants can offer significant benefits in terms of flexibility in matching a fluctuating power demand, particularly when coupled with wind turbines. For the hybrid power plant considered in this study, results show that advantages in terms of economics, energy savings and CO2 mitigation can be achieved.

Even in the absence of depraved terrorist threats, nuclear plants have been designed to respond safely to postulated accidents. Redundant safety features are built into plants to trigger safe shutdown and containment of possible accidents. The defined accidents range from minor leakage and operator errors to a complete loss of coolant from the reactor. Post-accident scenarios are postulated by experts in reactor and containment thermal-hydraulics, and all other sciences embraced by nuclear power plant design. The probability of failure is determined for all engineered safety systems. Then analytical and experimental programs are employed to predict the long term post-accident thermal-hydraulic state of a plant and its effect on the environment. The postulated accidents and safety system responses include effects resulting from mechanical damage and component malfunctions, such as pipe ruptures and the failure of pumps and valves. The initiating causes can be material failure, human error, and environmental effects from earthquakes, floods, and other severe acts of nature. It is prudent to build on an already established safety and accident technology to include the effects of external, planned attacks on a nuclear plant. This process includes “matching wits” with the minds of those who plot evil, and reinforcing protective security barriers where potential vulnerabilities are detected. Hard questions to ask and answer are, “What are the greatest potential security threats to a nuclear power plant? What possible human activity could make them happen? How can they be prevented?” Reactor and containment thermal-hydraulics contributes significantly to answering these questions.

Abstract Coordinated control between reactor and turbine is taken by Co-commissioning test between turbine governing system (GRE) and reactor rod position control system (RGL). Matching and completeness of interfaces between reactor and turbine could not be verified by static verification methodology before the unit starts up. Characteristics of coordinated control are analyzed in pressurized water reactor plant. Simulation Co-commissioning test program by static and dynamic verification methodologies between turbine governing system and rod position control system is put forward based on functional classification of interfaces signals. Static characteristics of interface signals between GRE and RGL are checked to verify static matching and completeness of interface signals by simulating the steam turbine to run under various operating conditions in verification method of static simulation. Dynamic response characteristic parameters of interface between GRE and RGL are analyzied and computed to verify dynamic matching and completeness of interface functions by simulating GRE and RGL to run under 4 typical coordinated control operating conditions in verification method of dynamic simulation. The case results have shown that matching and completeness of coordinated control interfaces between reactor and turbine can be verified efficiently by applying the test program into nuclear power plants successfully. And dynamic logic problems of interface are discovered and solved before the unit starts up.

In this work we consider the problem of parametrizing the set of all stabilizing Linear Time-Invariant (LTI) controllers for multirate systems such that model matching is achieved with a desired transfer function. We consider those systems where the plant output can be measured at a rate (measurement update rate) slower than the control signal updates rate. The solution to the parametrization problem is provided for the two cases: (1) model matching at the control update rate, (2) model matching at the measurement update rate. Unlike model matching at the measurement update rate, model matching at the control update rate allows us to directly improve and characterize the transient response of the continuous-time system. Tools such as up-sampling and down-sampling operators, and modified Z-transforms are utilized to model the closed-loop multirate system and to parametrize the sets of LTI controllers.
