The monograph presents a methodology for assessing the vulnerability of landscapes to external influences. A comparative analysis of the concepts of "stability", "sensitivity", "vulnerability" in relation to natural complexes. An overview of existing methods for assessing the vulnerability of natural complexes is presented. The author's method of assessing the vulnerability of landscapes to anthropogenic impacts is described. The methodology is based on: selection and justification of criteria for assessing the vulnerability of landscapes; preparation of a parametric matrix and gradation of assessment criteria in accordance with the developed vulnerability classes; calculation of weighting factors of vulnerability assessment parameters; selection of optimal territorial operational unit for landscape vulnerability assessment. The method is implemented in the GIS environment "Assessment of vulnerability of landscapes of the Kaliningrad region to anthropogenic impacts", created by the authors using modern geoinformation products. The specificity of spatial differentiation of different landscapes in terms of vulnerability to anthropogenic impacts at the regional and local levels is revealed. It is stated that the use of the methodology for assessing the vulnerability of landscapes to anthropogenic impacts and its integration into the system of nature management will ensure a balanced account of geoecological features and environmental priorities in territorial planning.
It is of interest to specialists in the field of rational nature management, environmental protection, spatial planning.

When considering the main trends in the development of modern autonomous objects (aircraft, combat vehicles, motor vehicles, floating vehicles, agricultural machines, etc.) in recent decades, two key areas can be identified. The first direction is associated with the improvement of traditional designs of autonomous objects (AO) with an internal combustion engine (ICE) or a gas turbine engine (GTD). The second direction is connected with the creation of new types of joint-stock companies, namely electric joint-stock companies( EAO), joint-stock companies with combined power plants (AOKEU).
The energy efficiency is largely determined by the power of the generator set and the battery, which is given to the electrical network in various driving modes.
Most of the existing methods for calculating power supply systems use the average values of disturbing factors (generator speed, current of electric energy consumers, voltage in the on-board network) when choosing the characteristics of the generator set and the battery. At the same time, it is obvious that when operating a motor vehicle, these parameters change depending on the driving mode. Modern methods of selecting the main parameters and characteristics of the power supply system do not provide for modeling its interaction with the power unit start-up system of a motor vehicle in operation due to the lack of a systematic approach.
The choice of a generator set and a battery, as well as the concept of the synthesis of the power supply system is a problem studied in the monograph.
For all those interested in electrical engineering and electronics.

<p>The seismic resilience of new and existing structures is a key priority for the protection of human lives and the reduction of economic losses in earthquake prone areas. The modern seismic codes have focused on the upgrade of the structural performance of the new and existing structures. However, in many cases it is preferrable to mitigate the effects of the earthquakes by reducing the induced loads in the structures using seismic isolation and response control devices. The limited expertise in the selection and design of the appropriate system for new and existing structures is the main challenge for an extensive use of seismic isolation and response control systems in practice.</p> <p>This document aims to provide a practical guide by presenting a collection of the most commonly used seismic isolation and response control systems and a critical evaluation of the main characteristics of these systems. Comparisons of the key parameters of the design processes for new buildings with seismic isolation are presented, while the application of seismic isolation systems and response control systems for the retrofitting of existing structures is also examined, followed by various case studies from Greece, Japan, Mexico, New Zealand, and Turkey.</p>

<p>Recent earthquakes have demonstrated that despite the continuous developments of novel materials and new strengthening techniques, the majority of the existing structures are still unprotected and at high seismic risk. The repair and strengthening framework is a complex process and there are often barriers in the preventative upgrade of the existing structures related to the cost of the applications and the limited expertise of the engineers. The engineers need to consider various options thoroughly and the selection of the appropriate strategy is a crucial parameter for the success of these applications.</p><p>The main aim of this collection is to present a number of different approaches applied to a wide range of structures with different characteristics and demands acting as a practical guide for the main repair and strengthening approaches used worldwide. This document contains a collection of nine case studies from six different countries with different seismicity (i.e. Austria, Greece, Italy, Mexico, Nepal and New Zealand). Various types of structures have been selected with different structural peculiarities such as buildings used for different purposes (i.e. school buildings, town hall, 30 storey office tower), a bridge, and a wharf. Most of the examined structures are Reinforced Concrete structures while there is also an application on a Masonry building. For each of the examined studies, the local conditions are described followed by the main deficiencies which are addressed. The methods used for the assessment of the in-situ conditions also presented and alternative strategies for the repair and strengthening are considered.</p>

This chapter proposes that spontaneous variation has a central role in biological evolution, operant conditioning, creative thinking, and personal agency. But to support these advantageous outcomes, this spontaneity must be joined with some selection process or procedure that decides which alleles, behaviors, ideas, or choices are most adaptive or useful. The argument begins with spontaneous variations in evolutionary theory, and then turns to operant conditioning, with emphasis on the origins of spontaneous behaviors. That analysis leads directly to a discussion that introduces a three-parameter definition of both creativity and sightedness, two concepts that provide the foundation for the blind-variation and selective-retention model of creativity. The latter is then linked with the chance-then-choice theory of free will, a linkage that makes spontaneous choice generation the first of two steps leading to personal agency. In all four phenomena, spontaneity is defined as the production of variants in ignorance of their actual utilities.

This chapter provides motivation for the rest of the book by giving a selection of simple examples showing how non-standard behaviour can occur. The well-known maximum likelihood estimator is used throughout this book to estimate an unknown vector of parameters. Its behaviour is standard if the log-likelihood is a concave quadratic function with the maximum in the neighbourhood of the true parameter value, but is otherwise non-standard. Examples of non-standard situations given in this chapter include the true parameter value not being an internal point of the parameter space, but being on a fixed boundary that may not even be finite, or where the mathematical form of the log-likelihood is different with non-estimable indeterminate parameters, or where the true model is an embedded model. Other examples given include where the log-likelihood is unbounded at a finite parameter point, is discontinuous, or is no longer quadratic.

Chapter 9, Approaches to Programming, provided a general discussion regarding the approaches to DBS programming. The focus of Chapter 9 was on the underlying electroneurophysiological principles rather an explicit algorithm that addressed every possible circumstance. Chapters 11, Chapter 12, and Chapter 13 discussed approaches in the context of specific DBS targets. These approaches emphasized interpreting the DBS responses to visualize the location of the DBS contacts in the unique regional anatomy of the individual patient. For example, the production of paresthesias at stimulation currents insufficient to produce clinical benefit with DBS in the vicinity of the STN indicates that the DBS lead position is probably too posterior. This chapter gives an algorithm that takes the programmer step by step through the process of positioning DBS leads and contacts, and determining stimulation levels for optimal results.

Chapter 5 returns to the blueprint for the evolution of sympathy in Darwin’s Descent, picking up at the point where Darwin introduces a paradoxical prediction of degeneration, caused by the same force that inspired social cohesion and moral progress. This chapter analyses the birth of the eugenics movement as a department of statistics, arising directly from a concern for the common good of civilised society – the central tenet of highly evolved sympathy. Unlike most studies of eugenics, this chapter focuses largely on the period before 1900, when the parameters of eugenic thought were being hashed out. It particularly focuses on the problem of degeneration as seen through the eyes of Francis Galton and Karl Pearson, who pointed to the need for social-policy interventions in breeding.

Insects dominate virtually all terrestrial and freshwater habitats on earth. This chapter reviews insect habitat selection, focusing on the occupation and defence of mating sites. First the adaptive basis of mating systems, sex roles, and behaviors in regard to habitat are established, then site occupation and defence in territorial species is explored. Resource-holding potential and resource value are discussed for how they determine aggressive motivation, as well as how contestants seek to gauge such parameters, with particular attention to the role of convention, drawing upon exemplar studies in damselflies and butterflies that have provided a narrative between theory and empiricism. Conventional and/or plastic behaviors are also discussed in terms of the presence and certainty of contestant roles, encompassing phenomena, such as residency confusion, nasty neighbours and interloper effects. The chapter concludes by discussing future avenues, foremost among which is the opportunity to synthesize empirical data across taxa.

Creative cognition is a critical aspect of creative problem solving for both teams and individuals, but the cognitive processes underlying creativity have received more attention at the individual than the team level. This chapter focuses on early- and late-stage cognitive processes that have currently received less attention in the team creativity literature: problem construction and idea evaluation and selection. Problem construction aims to clarify problem ambiguity through restating and redefining a problem and identifying goals and parameters for consideration prior to solution generation. Idea evaluation and selection occurs after idea generation and refers to the evaluation of ideas with respect to specific standards, goals, or ideals, and the selection of ideas for pursuit in implementation. Additional research for team problem construction and team idea evaluation and selection is proposed.

The phenotypes of those individuals with which an focal individual interacts often influences the trait value in the focal individual. Maternal effects is a classic example of this phenomena, as is fitness. If these traits are heritable, then the selection response depends on both the change in the direct effects influencing a target trait and the associative effects contributed by interacting individuals. In such a setting, the breeder's equation no longer holds, as the problem is now a multiple trait one. This chapter examines the theory of response under models with both direct and associative effects, which can lead to a reversed response (a trait selected to increase instead decreases). The evolution of behavioral traits, including the evolution of altruism, is best handled using this approach. Further, kin and group selection follow as special cases of the gerenal model under multilevel selection. This chapter also examines how mixed models can be used estimate model parameters.

Quantitative traits—be they morphological or physiological characters, aspects of behavior, or genome-level features such as the amount of RNA or protein expression for a specific gene—usually show considerable variation within and among populations. Quantitative genetics, also referred to as the genetics of complex traits, is the study of such characters and is based on mathematical models of evolution in which many genes influence the trait and in which non-genetic factors may also be important. Evolution and Selection of Quantitative Traits presents a holistic treatment of the subject, showing the interplay between theory and data with extensive discussions on statistical issues relating to the estimation of the biologically relevant parameters for these models. Quantitative genetics is viewed as the bridge between complex mathematical models of trait evolution and real-world data, and the authors have clearly framed their treatment as such. This is the second volume in a planned trilogy that summarizes the modern field of quantitative genetics, informed by empirical observations from wide-ranging fields (agriculture, evolution, ecology, and human biology) as well as population genetics, statistical theory, mathematical modeling, genetics, and genomics. Whilst volume 1 (1998) dealt with the genetics of such traits, the main focus of volume 2 is on their evolution, with a special emphasis on detecting selection (ranging from the use of genomic and historical data through to ecological field data) and examining its consequences. This extensive work of reference is suitable for graduate level students as well as professional researchers (both empiricists and theoreticians) in the fields of evolutionary biology, genetics, and genomics. It will also be of particular relevance and use to plant and animal breeders, human geneticists, and statisticians.

We present a rigorous but understandable introduction to the field of sampling theory for ecologists and natural resource scientists. Sampling theory concerns itself with development of procedures for random selection of a subset of units, a sample, from a larger finite population, and with how to best use sample data to make scientifically and statistically sound inferences about the population as a whole. The inferences fall into two broad categories: (a) estimation of simple descriptive population parameters, such as means, totals, or proportions, for variables of interest, and (b) estimation of uncertainty associated with estimated parameter values. Although the targets of estimation are few and simple, estimates of means, totals, or proportions see important and often controversial uses in management of natural resources and in fundamental ecological research, but few ecologists or natural resource scientists have formal training in sampling theory. We emphasize the classical design-based approach to sampling in which variable values associated with units are regarded as fixed and uncertainty of estimation arises via various randomization strategies that may be used to select samples. In addition to covering standard topics such as simple random, systematic, cluster, unequal probability (stressing the generality of Horvitz–Thompson estimation), multi-stage, and multi-phase sampling, we also consider adaptive sampling, spatially balanced sampling, and sampling through time, three areas of special importance for ecologists and natural resource scientists. The text is directed to undergraduate seniors, graduate students, and practicing professionals. Problems emphasize application of the theory and R programming in ecological and natural resource settings.

This chapter defines the parameters of the concept of resurrection in early Judaism and charts its reception within various literary genres. Within a diverse conceptual environment of attitudes toward death and human existence, resurrection made bold and selective claims about divine agency, the characteristics of embodied life, and the location of human existence within the larger spatial arena of the cosmos. The representation of resurrection in early Jewish literature is increasingly strong across a variety of literary genres and works of regionally diverse origins. The chapter criticizes the myth, however, that it was somehow dominant within early Judaism. Instead, resurrection emerged as a controversial theodicy within a larger conceptual arena in which attitudes toward death and the body became matters of intense dispute among competing scribal circles within the Hellenistic era.

Symptoms of post-traumatic stress disorder (PTSD) often fail to resolve with psychotherapy, pharmacotherapy, or integrative medicine treatments. Given these limitations, there is a continued push to discover treatment methods utilizing novel mechanisms of action. Transcranial magnetic stimulation (TMS) offers a non-invasive and safe method of brain stimulation that modulates neuronal activity in a focal area to achieve excitation or inhibition, and may have utility for patients suffering from PTSD, although, to date, evidence of efficacy is limited. The TMS treatment can be varied to suit the needs of the patient by altering the selection of the specific treatment parameters, such as pulse frequency or stimulation intensity. The weight of evidence to date supports treatment of either the right dorsolateral prefrontal cortex or the medical prefrontal cortex. Coupling treatment with script based exposure therapies may also assist with potentiation of the extinction response. Ultimately, stimulation parameters may be related to secondary downstream effects, and thus current targets may indirectly reverse the underlying neuronal pathophysiology. Given that PTSD is a complex illness with a poorly understood pathophysiology, it often exists with other psychiatric comorbidities or TBI. As such, TMS could be an effective part of a comprehensive treatment program.

Phenomenological models mathematically describe relationships among empirically observed phenomena without attempting to explain underlying mechanisms. Within the context of NLTS, phenomenological modeling goes beyond phase space reconstruction to extract equations governing real-world system dynamics from a single or multiple observed time series. Phenomenological models provide several benefits. They can be used to characterize the dynamics of variable interactions; for example, whether an incremental increase in one variable drives a marginal increase/decrease in the growth rate of another, and whether these dynamic interactions follow systematic patterns over time. They provide an analytical framework for data driven science still searching for credible theoretical explanation. They set a descriptive standard for how the real world operates so that theory is not misdirected in explaining fanciful behavior. The success of phenomenological modeling depends critically on selection of governing parameters. Model dimensionality, and the time delays used to synthesize dynamic variables, are guided by statistical tests run for phase space reconstruction. Other regression and numerical integration parameters can be set on a trial and error basis within ranges providing numerical stability and successful reproduction of empirically-detected dynamics. We illustrate phenomenological modeling with solutions of the Lorenz model so that we can recognize the dynamics that need to be reproduced.

This chapter describes the ways in which the Monte Carlo importance sampling method may be adapted to improve the calculation of ensemble averages, particularly those associated with free energy differences. These approaches include umbrella sampling, non-Boltzmann sampling, the Wang–Landau method, and nested sampling. In addition, a range of special techniques have been developed to accelerate the simulation of flexible molecules, such as polymers. These approaches are illustrated with scientific examples and program code. The chapter also explains the analysis of such simulations using techniques such as weighted histograms, and acceptance ratio calculations. Practical advice on selection of methods, parameters, and the direction in which to make comparisons, are given. Monte Carlo methods for modelling phase equilibria and chemical reactions at equilibrium are described.

Deep-brain stimulation is a last resort for the management of dystonia or dystonic movement disorders when oral or injectable therapies do not provide adequate relief to allow an acceptable quality of life. The underlying pathogenesis of dystonia is less well understood than in Parkinson’s disease, in which deep-brain stimulation is generally expected to provide effective and long-lasting benefit. Furthermore, it is likely that dystonia represents a number of different basal ganglia pathologies. The response of dystonia to deep-brain stimulation is typically delayed for up to weeks or months following a change in stimulation parameters. All of these factors make it more difficult to predict outcomes in dystonia following deep-brain stimulation, thus making patient selection all the more important.

Chapter 7 begins with an outline and description of five threats to internal validity common to time series designs: history, maturation, instrumentation, regression, and selection. Given the fundamental role of prediction in the modern scientific method, scientific hypotheses are necessarily causal. After an outline of the evolving definition of “causality” in the social sciences, contemporary Rubin causality or counterfactual causality is introduced. Under the assumption that subjects were randomly assigned to the treatment and control groups, Rubin’s causal model allows one to estimate the unobserved causal parameter from observed data. Control time series are chosen so as to render plausible threats to internal validity implausible. An appropriate control time series may not exist, however, an ideal time series may be possible to construct. Synthetic control group models construct a control time series that optimally recreates the treated unit’s preintervention trend using a combination of untreated donor pool units.

Using household data from the latest wave of the Ghana Living Standards Survey, this paper utilizes machine learning techniques to examine the effect of gender wage differences within households on women’s empowerment and welfare in Ghana. The structural parameters of the post-double selection LASSO estimations show that a reduction in household gender wage gap significantly enhances women’s empowerment. Also, a decline in household gender wage gap results meaningfully in improving household welfare. Particularly, the increasing effect on women’s welfare resulting from decreases in household gender wage differences is much higher than for the household welfare. The findings showcase the need to vigorously adopt policies that both increase the quantity and quality of jobs for women and address gender barriers that inhibit women from accessing these jobs opportunities in sub-Saharan Africa.

This chapter proposes a systems-theoretic adjustment to conceptual blending theory with respect to the so-called generic space. In creative conceptualization, the generic space is not an optional by-product of conceptual mappings across previously and otherwise constituted input spaces, but rather their effective cause, and not by selecting for them but by massively constraining against anything not them. As a first approximation of the blend’s targeted or intended meaning, the generic space functions as an indispensable “proto-blend” that sets the parameters and satisfaction conditions for the resulting conceptual network. This underappreciated point is elaborated through case studies of three well-known and increasingly complex creative blends: a sentence-level metaphor (“This surgeon is a butcher!”), an extemporaneous discourse exchange (from the live radio talk show “Loveline”), and a highly iconic lyric poem (Richard Wilbur’s “Piazza di Spagna, Early Morning”).

Practical Nitriding and Ferritic Nitrocarburizing addresses many questions that arise when using nitriding and nitrocarburizing processes to case harden engineered components. It describes the basic chemistry of each process and its effect on the metallurgy and microstructure of different grades of iron and steel. It explains how the processes and their variants are implemented and how to set up, monitor, and control process equipment to meet specific design objectives. It discusses the factors that must be considered when selecting materials and determining parameters related to surface hardness, case depth, compound zone thickness, corrosion and wear resistance, distortion, and other such variables. It also explains how materials should be prepared and handled before and after processing, how to examine and evaluate results, and how to diagnose and fix problems.

This chapter describes the key investigations used in the diagnosis of sleep disorders. The recording and value of polysomnography (PSG), with and without electroencephalography is discussed, including the specific parameters essential for the various sleep related breathing disorders. The technical aspects of the multiple sleep latency test and maintenance of wakefulness test are followed by interpretation of findings, recognizing their limitations, especially in adults with co-morbid disorders, and the effect of medication and also shift work. Finally, the value of wrist actigraphy as a diagnostic tool in circadian rhythm sleep–wake disorders is discussed. The chapter emphasizes the importance of selecting appropriate tests based on clinical information and the importance of units providing diagnostic studies for sleep disorders, constantly reviewing their study protocols and auditing inter-rater reliability of PSG sleep staging in children and adults of various ages and sleep disorders.

Mathematical psychology and systems neuroscience have converged on stochastic accumulator models to explain decision making. We examined saccade decisions in monkeys while neurophysiological recordings were made within their frontal eye field. Accumulator models were tested on how well they fit response probabilities and distributions of response times to make saccades. We connected these models with neurophysiology. To test the hypothesis that visually responsive neurons represented perceptual evidence driving accumulation, we replaced perceptual processing time and drift rate parameters with recorded neurophysiology from those neurons. To test the hypothesis that movement related neurons instantiated the accumulator, we compared measures of neural dynamics with predicted measures of accumulator dynamics. Thus, neurophysiology both provides a constraint on model assumptions and data for model selection. We highlight a gated accumulator model that accounts for saccade behavior during visual search, predicts neurophysiology during search, and provides insights into the locus of cognitive control over decisions.

This chapter focuses on genetic programming (GP), a stochastic optimization and model induction technique. An advantage of GP is that the modeler need not select the exact parameters to be used in the model beforehand. Rather, GP can effectively search a complex model space defined by a set of building blocks specified by the modeler. This flexibility has allowed GP to be used for many applications. The chapter reviews some of the most significant developments using GP: forecasting, stock selection, derivative pricing and trading, bankruptcy and credit risk assessment, and agent-based and economic modeling. Conclusions reached by studies investigating similar problems do not always agree; however, GP has proved useful across a wide range of problem areas. Recent and future work is increasingly concerned with adapting genetic programming to more dynamic environments and ensuring that solutions generalize robustly to out-of-sample data, to further improve model performance.

This chapter will explicate a new teleological argument for theism, one based on the intelligibility of the universe and the science-friendly character of the laws of nature. Specifically, it begins by presenting some of the preliminary evidence that the fundamental parameters of physics fall in a relatively small range that maximizes our ability to make scientific discoveries. This is called as the “fine-tuning for scientific discovery.” It then shows how this fine-tuning provides potentially powerful new evidence for theism. Unlike the much discussed anthropic fine-tuning (or fine-tuning for life), this kind of fine-tuning cannot be explained by the multiverse hypothesis since it does not encounter an observer-selection effect. Further, it avoids some other objections commonly raised against the anthropic fine-tuning argument, such as the so-called normalizability problem. Consequently, this new fine-tuning argument has the potential of providing an outstanding supplement to the standard anthropic fine-tuning argument for theism.

Disseminated intravascular coagulation (DIC) is a syndrome characterized by systemic intravascular activation of coagulation, leading to widespread deposition of fibrin in the circulation. In patients with DIC, a variety of altered coagulation parameters may be detectable, such as thrombocytopenia, prolonged global coagulation times, reduced levels of coagulation inhibitors, or high levels of fibrin split products. There is not a single test, however, that is sufficiently accurate to establish or reject a diagnosis of DIC. Nevertheless, a combination of widely available tests may be helpful in making the diagnosis of DIC and can also be helpful in guiding the selection of DIC patients that require specific, often expensive, interventions in the coagulation system. Recent knowledge on important pathogenetic mechanisms that may lead to DIC has resulted in novel preventive and therapeutic approaches to patients with DIC. Strategies aimed at the inhibition of coagulation activation may theoretically be justified and have been found beneficial in experimental and clinical studies. These strategies comprise inhibition of tissue factor-mediated activation of coagulation or restoration of physiological anticoagulant pathways.

This book provides comprehensive details on a number of well-defined genetic disorders and a selection of less well-defined entities that include somatic overgrowth as a major manifestation. In addition to overgrowth, these syndromes each have their own distinguishing characteristics that benefit the clinician in making a specific diagnosis. In most cases, the causative genes are known, giving a means of laboratory confirmation of the diagnoses. A major distinction from other hereditary syndromes is a predisposition of patients with the overgrowth syndromes to develop neoplasms during childhood. In some cases, the overgrowth seems to be limited, even to the extent that some growth parameters may return to the normal range by adulthood. In other cases, the overgrowth is notable throughout life. In recent years, both the generalized and the segmental overgrowth syndromes have begun to yield their secrets to molecular technologies. These studies have provided clinicians a way to confirm the specific diagnosis so they can provide appropriate counseling and anticipatory management. In the case of segmental overgrowth disorders, they have also established their mosaic nature, which explains the sporadic occurrence and marked phenotype variability.

Modern practice of ecology, conservation, and resource management demands unprecedented levels of quantitative proficiency in mathematical modeling and statistics. This text provides foundational training in the concepts and methods of mathematical and statistical modeling used in ecology, for readers with all levels of quantitative proficiency and confidence. The first chapter presents a generalized approach to develop ecological models and introduces the “describe, explain, and interpret” framework for linking the model world to the real world. Detailed treatment of population models illustrates the myriad ways in which one can develop a model, shows how modeling choices are informed by the ecological question at hand, and emphasizes the epistemology of quantitative techniques. The second part of the book illustrates how to estimate parameters of models from data, and how to use mathematical models combined with statistics to test hypotheses. The third part of the book is devoted to an in-depth development of technical skills to implement models in two common platforms: spreadsheets and the R programming language. The book concludes by demonstrating a quantitative approach to addressing a question that spans density-dependent versus density-independent population models, fitting models to data, evaluating the strength for density dependence using model selection, and evaluating the types of dynamic behaviors that the population might exhibit.

This chapter summarizes current best practice with respect to intermittent haemodialysis and sustained low-efficiency dialysis (SLED) for those with acute kidney injury. These modalities can be delivered using a variety of technology platforms. These platforms for the most part use online dialysate, and water quality needs to be monitored and maintained to current standards. Intermittent haemodialysis and SLED provide reasonable outcomes in experienced hands, and ameliorate morbidity and mortality resulting from the ‘acute uraemic syndrome’: that is, intractable infection, non-resolving shock, and haemorrhage.Careful consideration needs to be given to appropriate modality selection for patients. Lower-efficiency modalities such as continuous therapies or SLED are more appropriate for patients at risk from dialysis disequilibrium syndrome, those with abdominal compartment syndrome, and those who are haemodynamically unstable (including cardiogenic shock). Care should be taken to avoid complications related to rapid fluid and solute removal, anticoagulation, and vascular access. Intradialytic hypotension is detrimental for both general and renal recovery of critically ill patients, and can be mitigated by sodium and ultrafiltration profiling, and frequent treatments and prolonged treatment time to minimize ultrafiltration goals and rates.Irrespective of the modality applied, an adequate dialysis dose must be achieved. This is facilitated through the use of optimally placed and technically superior central venous catheters, and well-considered prescription of haemodialysis and SLED operating parameters. Dose should be monitored regularly through urea kinetic modelling, either using Kt/V for thrice-weekly schedules or the corrected equivalent renal urea clearance (EKRc) for more frequent ones.

Transition of acute myocarditis to dilated cardiomyopathy occurs in approximately 20% of patients within a follow-up period of 33 months. Recent research has revealed the adverse prognostic impact of several clinical parameters for this scenario. Acute myocarditis and its sequelae dilated cardiomyopathy and inflammatory cardiomyopathy are often caused by viral infections. Histological evaluation of endomyocardial biopsies is critical for the diagnosis of the cardiomyopathy entity and for the clinical management of around 20% of the patients. Additionally, contemporary diagnostic procedures of endomyocardial biopsies are indispensable for the selection of inflammatory cardiomyopathy patients who will likely benefit from immunosuppression or antiviral (interferon) treatment. Immunoadsorption, with subsequent immunoglobulin substitution, is a further promising immunomodulatory treatment option for dilated cardiomyopathy patients, targeting primarily the anticardiac autoantibodies. Cardiac magnetic resonance has emerged as a valuable diagnostic approach for myocarditis and pericarditis. Myocardial late gadolinium enhancement has been associated with adverse outcome and sudden cardiac death. Bridging of the first 3–6 months with a wearable cardioverter–defibrillator, until a definitive decision on the implantation of an implantable cardioverter–defibrillator, is a growingly recognized cornerstone in the clinical management of patients with acute myocarditis with depressed left ventricular ejection fraction of <40% and new-onset dilated cardiomyopathy, respectively. Acute pericarditis is labelled idiopathic or suspected viral without adequate proof of the respective aetiology. Non-steroidal anti-inflammatory drugs and colchicine are proven and safe therapeutic mainstays for pericarditis, including the first attack. Pericardiocentesis is a lifesaving treatment of cardiac tamponade. Pericardioscopy and epicardial biopsies can contribute to the aetiological differentiation of pericardial effusions.

The objective of the present work was to evaluate the individual quality of male European roe deer by statistical analysis of antler traits, craniometric characters, and age of hunter-harvested bucks. Those measurements enabled a reliable assessment of antler quality, changes in carcass weight with age and between hunting seasons, as well as phenotypic traits depending on habitat (percentage forest cover, geographic mesoregion). The work also aimed to assess the effectiveness of deer population management in the Cracow Region of the Polish Hunting Association and determine the potential of that population based on analysis of medal-quality roebucks harvested there over the past 10 years. The study involved data concerning roe deer in the 60 hunting districts comprising the Cracow Region for the 2008/2009-2017/2018 hunting seasons. The study material consisted of data concerning antlers from 8132 roebucks taken over that decade, such as the age of hunted roebucks, hunting district, hunt date, carcass weight, as well as the gross weight and form of antlers. A detailed evaluation of antler quality was conducted using records for 2874 individuals, including 284 medal-quality antlers, harvested in the 2014/2015-2016/2017 seasons. The trophies were evaluated in accordance with the criteria of the International Council for Game and Wildlife Conservation (CIC) and were subjected to craniometric analysis. For a comprehensive examination of roe deer quality in the Cracow Region, the study analyzed gamekeeping data, that is, annual hunting plans of the Polish Hunting Association, for the period 2008/2009-2017/2018. Several gamekeeping indicators were calculated based on those data to evaluate the effects of roe deer management and gamekeeping practices. The studied antler traits (mean beam length, antler weight and volume, CIC scores) as well as carcass weight culminated in 6-year-old individuals. In turn cra-niometric traits (skull length and width) increased significantly until the 4th year of life, while the width of pedicles increased throughout the life of the individual. The development of antlers over time was characterized by a declining rate of growth for all the analyzed parameters. The highest growth rate (more than 100%) was found between the second and third years of life in terms of antler weight and volume, as well as front tine length. Antler quality in terms of overall CIC scores was to the greatest extent affected by weight and volume. The combined contribution of these factors increased with age, and ranged from 63.9% in the youngest individuals to 74.6% in the oldest ones. Within the study area, the individual quality of roe deer varied depending on the forest cover and mesoregion. Roebucks with the lowest carcass and antler weight occurred in hunting districts with a forest cover exceeding 40%, while the highest values of those parameters were found in districts with 5% forest cover or less. In open-land areas, the share of medal-quality roebucks in the total number of harvested males was higher, at approx. 5%, as compared to 1.29% in the woodlands. The carcass and antler weight of roebucks taken in the Cracow Region was higher than that of roebucks harvested in western Poland, similar to the Kielce Region, and lower than that for the Lublin and Krosno Regions, which is in keeping with Bergmann's ecogeographical rule. Analysis of carcass weight throughout the hunting season showed that the most pronounced rutting activity was observed for individuals 6 years of age and older, which lost as much as 6% of their weight. Over the ten-year period of study, the roebucks harvested using a uniform set of selection criteria revealed an increase in mean carcass weight as well as antler weight and form, which indicates appropriate management of the roe deer population in the examined hunting region.
