description: Background and purpose — Antibiotic treatment of patients before specimen collection reduces the ability to detect organisms by culture. We investigated the suppressive effect of antibiotics on the growth of non-adherent, planktonic, and surface-related biofilm bacteria in vitro by using sonication and microcalorimetry methods. Patients and methods — Biofilms of Staphylococcus aureus, S. epidermidis, Escherichia coli, and Propionibacterium acnes were formed on porous glass beads and exposed for 24 h to antibiotic concentrations from 1 to 1,024 times the minimal inhibitory concentration (MIC) of vancomycin, daptomycin, rifampin, flucloxacillin, or ciprofloxacin. The beads were then sonicated to dislodge biofilm, followed by culture and measurement of growth-related heat flow by microcalorimetry of the resulting sonication fluid. Results — Vancomycin did not inhibit the heat flow of staphylococci and P. acnes at concentrations ≤1,024 μg/mL, whereas flucloxacillin at >128 μg/mL inhibited S. aureus. Daptomycin inhibited heat flow of S. aureus, S. epidermidis, and P. acnes at lower concentrations (32–128 times MIC, p < 0.001). Rifampin showed inconsistent results in staphylococci due to random emergence of resistance, which was observed at concentrations ≤1,024 times MIC (i.e. 8 μg/mL). Ciprofloxacin inhibited heat flow of E. coli at ≥4 times MIC (i.e. ≥ 0.06 μg/mL). Interpretation — Whereas time-dependent antibiotics (i.e. vancomycin and flucloxacillin) showed only weak growth suppression, concentration-dependent drugs (i.e. daptomycin and ciprofloxacin) had a strong suppressive effect on bacterial growth and reduced the ability to detect planktonic and biofilm bacteria. Exposure to rifampin rapidly caused emergence of resistance. Our findings indicate that preoperative administration of antibiotics may have heterogeneous effects on the ability to detect biofilm bacteria.

description: Objectives: 1) To identify laparoscopic colorectal surgery practice patterns in Canada, 2) To systematically review the literature comparing hand assisted laparoscopic surgery to conventional laparoscopic surgery and 3) To design a randomized controlled trial protocol comparing conventional laparoscopic to hand assisted laparoscopic colorectal resections. Methods: A national cross sectional study was undertaken of Canadian General Surgeons with respect to their practice patterns specific to laparoscopic colorectal surgery. A systematic review comparing Conventional laparoscopic to Hand-Assisted Laparoscopic colorectal resections. A randomized controlled trial protocol with methodological discussions regarding issues in surgical trials was written. Results: The majority of Canadian General Surgeons are offering laparoscopic colorectal resections although the volume per surgeon appears to be low. The main barriers to adoption are operating time and lack of formal minimally invasive surgery training. There were two trials identified for inclusion in the systematic review with a total of 94 subjects with some methodological weaknesses. A potential trend towards decreased conversion to open surgery in the hand assisted group was identified. A protocol is presented for a trial comparing hand assisted to conventional laparoscopic colorectal surgery. Conclusion: A large percentage of Canadian surgeons perform laparoscopic colorectal resections although many perform less than one case per month. The limited number of trials performed and their associated methodological weaknesses and heterogeneity does not allow a reliable assessment of the relative benefits of hand-assisted and conventional laparoscopic resections for colorectal disease. Additional adequately powered and methodologically sound trials are needed to determine if there is a clinically important difference in perioperative outcomes.

description: With the enhanced performance of modern personal computer systems, the acceptance and distribution of 3D and virtual environment (VE) applications have become more common. The first VE systems were single user systems, but now we can see that distributed VE (DVE) and CSCW (Computer Supported Collaborative Work) can open new areas of applications. Currently one of the most challenging areas of research in Virtual Reality is Collaborative Virtual Environment (CVE). It adds new dimensions to human-factors, networking, synchronization, middleware, object model acquisition and representation. Some international standards have been developed that are very likely to make a major impact on CVE technology: the Distributed Interactive Simulation (DIS) and the High Level Architecture (HLA). Deriving from military-purpose simulations, DIS and HLA, however, have limitations on building large-scale general-purpose CVE applications. For instance, HLA ownership management only allows single participant to manipulate objects at any given time while providing meaningful real-time manipulation of a single object among multiple geographically distant users is essential for users performing collaborative tasks. The mobile agent technology that has received a rapidly growing attention over the last few years overcomes these limitations and could be an effective solution to building large-scale general-purpose CVE applications. This research addresses the software architecture and techniques necessary to apply the philosophy of mobile agents to collaborative virtual environments. For this purpose, a mobile agent system called MAP is designed and implemented. MAP supports general-purpose CVEs, enables object dynamic introduction, joint-manipulation management and maximizes system flexibilities such as dynamic composition and task coordination that are applied for building a workload balanced interest management system.
Gravitational dynamics of a relativistic binary pulsar and a probe of radio pulsar intermittency
Creators: name: Venkatraman Krishnan, Vivek
Publisher: name: Swinburne
Year: 2024

description: The thesis uses observations of radio pulsations from a neutron star in a binary orbit around a white dwarf star to understand the motion of the star as postulated by Einstein's General theory of Relativity. The pulsar's orbit is seen to wobble as a result of the fast rotation of the white dwarf, something seen for the first time in binary star systems. The second part of the thesis deals with the development of a fully robotic system of observation and data analysis with the Molonglo radio telescope to search for radio pulsations from other yet undiscovered neutron stars.

description: Intensification of agricultural practices has resulted in a substantial decline of Europe's farmland bird populations. Together with increasing urbanisation, chemical pollution arising from these land uses is a recognised threat to wildlife. Raptors are known to be particularly sensitive to pollutants that biomagnify and are thus frequently used sentinels for pollution in food webs. The current study focussed on anticoagulant rodenticides (ARs) but also considered selected medicinal products (MPs) and frequently used plant protection products (PPPs). We analysed livers of raptor species from agricultural and urban habitats in Germany, namely red kites (MIML; Milvus milvus), northern goshawks (ACGE; Accipiter gentilis) and Eurasian sparrowhawks (ACNI; Accipiter nisus) as well as white-tailed sea eagles (HAAL; Haliaeetus albicilla) and ospreys (PAHA; Pandion haliaetus) to account for potential aquatic exposures. Landscape composition was quantified using geographic information systems. The highest detection of ARs occurred in ACGE (81.3%; n = 48), closely followed by MIML (80.5%; n = 41), HAAL (38.3%; n = 60) and ACNI (13%; n = 23), whereas no ARs were found in PAHA (n = 13). Generalized linear models demonstrated (1) an increased probability for adults to be exposed to ARs with increasing urbanisation, and (2) that species-specific traits were responsible for the extent of exposure. For MPs, we found ibuprofen in 14.9% and fluoroquinolones in 2.3% in individuals that were found dead. Among 30 investigated PPPs, dimethoate (and its metabolite omethoate) and thiacloprid were detected in two MIML each. We assumed that the levels of dimethoate were a consequence of deliberate poisoning. AR and insecticide poisoning were considered to represent a threat to red kites and may ultimately contribute to reported decreased survival rates. Overall, our study suggests that urban raptors are at greatest risk for AR exposure and that exposures may not be limited to terrestrial food webs. © 2020 The Authors

description: Eosinophilic esophagitis (EoE) is an atopic condition of the esophagus that has become increasingly recognized over the last 15 years. Diagnosis of the disorder is dependent on the patient’s clinical manifestations, and must be confirmed by histologic findings on esophageal mucosal biopsies. Patients with EoE should be referred to an allergist for optimal management, which may include dietary modifications and pharmacologic agents such as corticosteroids, and for the diagnosis and management of comorbid atopic conditions. Mechanical dilation of the esophagus may also be necessary. The epidemiology, pathophysiology, diagnosis, treatment, and prognosis of EoE are discussed in this review.

description: Introduction The birth of most mammals features a dramatic increase in oxygen while placenta-derived hormones such as β-estradiol and progesterone plummet. In experimental newborn animals, transiently elevated oxygen concentrations cause death of neurons, astrocytes, and oligodendrocyte precursors. High oxygen has been associated with cerebral palsy in human preterm infants while progesterone is being used to prevent preterm delivery and investigated as a neuroprotective agent. Methods In this study, we investigated the effects of hyperoxia (80% O2 for 24, 48, and 72 h) on cultured C8-D1A astrocytes in the presence or absence of progesterone at concentrations ranging from 10−9 to 10−5 mol/L. Results Hyperoxia measured by methytetrazolium assay (MTT) reduced cell viability, increased release of lactate dehydrogenase (LDH), reduced carboxyfluorescein diacetate succinimidyl ester (CFSE)-assessed cell proliferation, and downregulated Cylin D2 expression. Progesterone did not affect any of these hyperoxia-mediated indicators of cell death or malfunctioning. Real-time PCR analysis showed that hyperoxia caused downregulation of the progesterone receptors PR-AB und PR-B. Conclusions Our experiments showed that there was no protective effect of progesterone on hyperoxia-inducted cell damage on mouse C8-D1A astrocytes. Down regulation of the progesterone receptors might be linked to the lack of protective effects.
Velocity and Acceleration Estimation and Uniform Hardness Perception in 6-DOF Haptic Rendering

description: With advances in human computer interface technologies, the sense of touch has been successfully brought into many virtual reality applications. Haptic devices are such kinds of interfaces which can generate programmable forces to its users, allowing for natural manipulations of objects inside virtual environments. In this thesis, we study two critical issues with haptic interfaces that have a tool-like end effector. The first issue is about velocity and acceleration estimation for haptic interfaces. Since most haptic devices are equipped with neither tachometers nor accelerometers, this information has to be derived from discrete position measurements. However, due to a limited sensor resolution and a fast update rate requirement of haptic simulations, getting accurate and robust estimates is challenging. In studies of human arm/hand trajectories, researchers observed that skilled movements are usually extremely smooth that is equivalent to minimizing an objective measure with a performance index of jerk. With the assumption of a constrained minimum-jerk model for human arm/hand trajectories, an adaptive constrained 4-state Kalman filter is proposed for the velocity and acceleration estimation for haptic devices. The second issue is about the influences of a haptic interface's effective mass and viscous damping on users' perceived virtual stiffness in 6-DOF haptic rendering. In any haptic simulations, we always hope that the desired force can be delivered to the user faithfully. But the inherent dynamics of the device may have negative effects on the final perceived force. Through experiments, we have found that the induced forces from those physical parameters affect the perceived virtual stiffness non-uniformly: a surface that should feel uniformly stiff will feel softer or harder, depending on which part of the virtual tool it contacts. The scale of the non-uniform perception is also related to the user's holding point as well as its relative position to the contact points on the tool. Nevertheless, the goal of this study is not to increase the perceived hardness but to make users perceive a uniform hardness when tapping a virtual object. For that, we propose three different methods to compensate for the non-uniform hardness perception. The subjective evaluations show the effectiveness of all three methods.

description: Objectives: The aim of this study was to measure the prevalence of skin diseases in aged nursing home residents and to explore possible associations with demographic and medical characteristics. Design: Descriptive multicentre prevalence study. Setting and participants: The study was conducted in a random sample of ten institutional long-term care facilities in the federal state of Berlin, Germany. In total, n=223 residents were included. Results: In total, 60 dermatological diseases were diagnosed. The most frequently diagnosed skin disease was xerosis cutis (99.1%, 95% CI 97.7% to 100.0%) followed by tinea ungium (62.3%, 95% CI 56.0% to 69.1%) and seborrheic keratosis (56.5%, 95% CI 50.2% to 63.0%). Only few bivariate associations have been detected between skin diseases and demographic and medical characteristics. Conclusion: Study results indicate that almost every resident living in residential care has at least one dermatological diagnosis. Dermatological findings range from highly prevalent xerosis and cutaneous infection up to skin cancer. Not all conditions require immediate dermatological treatment and can be managed by targeted skin care interventions. Caregivers need knowledge and diagnostic skills to make appropriate clinical decisions. It is unlikely that specialised dermatological care will be delivered widely in the growing long-term care sector.

description: Neonatal tumors are rare with no standard treatment approaches to these diseases, and the patients experience poor outcomes. Our aim was to determine the distribution of cancers affecting neonates and compare survival between these cancers and older children. We analyzed SEER data (1973–2007) from patients who were younger than 2 years at diagnosis of malignancy. Special permission was granted to access the detailed (i.e., age in months) data of those patients. The Chi-square Log-rank test was used to compare survival between neonates (aged <1 month) and older children (>1 month to <2 years). We identified 615 neonatal cancers (454 solid tumors, 93 leukemia/lymphoma, and 68 CNS neoplasms). Neuroblastoma was the most common neonatal tumor followed by Germ cell tumors. The 5-year overall survival (OS) for all neonates was 60.3% (95% CI, 56.2–64.4). Neonates with solid tumors had the highest 5-year OS (71.2%; 95% CI, 66.9–75.5), followed by those with leukemia (39.1%; 95% CI, 28.3–49.9) or CNS tumors (15%; 95% CI, 5.4–24.6). Except for neuroblastoma, all neonatal tumors showed inferior outcomes compared to that in the older group. The proportion of neonates who died from causes other than cancer was significantly higher than that of the older children (37.9% vs. 16.4%; P < 0.0005). In general, the outcome of neonatal cancers has not improved over the last 34 years. The distribution of neonatal cancer is different than other pediatric age groups. Although the progress in neonatal and cancer care over the last 30 years, only death from noncancer causes showed improvement. Studying neonatal tumors as part of national studies is essential to understand their etiology, determine the best treatment approaches, and improve survival and quality of life for those patients.

Drug allergy

description: Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions with varying mechanisms and clinical presentations. This type of adverse drug reaction not only affects patient quality of life, but may also lead to delayed treatment, unnecessary investigations, and even mortality. Given the myriad of symptoms associated with the condition, diagnosis is often challenging. Therefore, referral to an allergist experienced in the identification, diagnosis and management of drug allergy is recommended if a drug-induced allergic reaction is suspected. Diagnosis relies on a careful history and physical examination and, in some instances, skin testing and graded challenges. Induction of drug tolerance procedures may also be required. The most effective strategy for the management of drug allergy is avoidance or discontinuation of the offending drug. When available, alternative medications with unrelated chemical structures should be substituted. Cross-reactivity among drugs should be taken into consideration when choosing alternative agents. Additional therapy for drug hypersensitivity reactions is largely supportive and may include topical corticosteroids, oral antihistamines and, in severe cases, systemic corticosteroids. In the event of anaphylaxis, the treatment of choice is injectable epinephrine. If a particular drug to which the patient is allergic is indicated and there is no suitable alternative, induction of drug tolerance procedures may be considered to induce temporary tolerance to the drug. This article provides a background on drug allergy and strategies for the diagnosis and management of some of the most common drug-induced allergic reactions, such as penicillin, sulfonamides, cephalosporins, radiocontrast media, local anesthetics, general anesthetics, acetylsalicylic acid and non-steroidal anti-inflammatory drugs, and therapeutic monoclonal antibodies.

description: During surgery or infection, peripheral inflammation can lead to neuroinflammation, which is associated with cognitive impairment, neurodegeneration, and several neurodegenerative diseases. Dexmedetomidine, an α-2-adrenoceptor agonist, is known to exert anti-inflammatory and neuroprotective properties and reduces the incidence of postoperative cognitive impairments. However, on the whole the molecular mechanisms are poorly understood. This study aims to explore whether dexmedetomidine influences microRNAs (miRNAs) in a rat model of lipopolysaccharide (LPS)-induced neuroinflammation. Adult Wistar rats were injected with 1 mg/kg LPS intraperitoneal (i.p.) in the presence or absence of 5 µg/kg dexmedetomidine. After 6 h, 24 h, and 7 days, gene expressions of interleukin 1-β (IL1-β), tumor necrosis factor-α (TNF-α), and microRNA expressions of miR 124, 132, 134, and 155 were measured in the hippocampus, cortex, and plasma. Dexmedetomidine decreased the LPS-induced neuroinflammation in the hippocampus and cortex via significant reduction of the IL1-β and TNF-α gene expressions after 24 h. Moreover, the LPS-mediated increased expressions of miR 124, 132, 134, and 155 were significantly decreased after dexmedetomidine treatment in both brain regions. In plasma, dexmedetomidine significantly reduced LPS- induced miR 155 after 6 h. Furthermore, there is evidence that miR 132 and 134 may be suitable as potential biomarkers for the detection of neuroinflammation. View Full-Text

description: Placental growth and development depend on highly regulated extravillous trophoblast (EVT) function, such as proliferation, migration and invasion. NUMB has been reported to playa role in cell differentiation and proliferation. An established cell line (HTR8/SVneo) was used as a model to study the role of NUMB in invasive extravillous trophoblast cell migration and survival in the human placenta. Immunofluorescence showed the presence of NUMB at the plasma membrane and the cytoplasmic region in HTR8/Svneo cells. NUMB isoform 1 significantly increased EVT migration while NUMB knockdown decreased the rate of migration as compared to the negative control. Overexpression of Numb 1,3,4 and 8 did not influence cellular viability whereas Numb 2 overexpression decreased trophoblast viability significantly. We have demonstrated for the first time that Numb is expressed in human invasive extravillous trophoblasts and that its role is isoform-dependent. Dysregulation of NUMB expression/function may playa role in placental pathologies such as preeclampsia and IUGR.

description: Recent events in global capital markets have underscored the impotence of securities regulation and paucity of ethical behaviour. With the resurgence of virtue ethics it only seems appropriate that a concerted effort should be undertaken to apply this model to the financial services industry. This thesis will apply Alasdair MacIntyre's tripartite notion of virtue ethics as explicated in his highly acclaimed work After Virtue to the role of the Investment Advisor in the Canadian financial services industry. MacIntyre's concepts of practice, narrative order of a single human life and the notion of tradition will be applied to the role of the Investment Advisor and the institutions that accommodate the profession. It will be concluded that MacIntyre's notions of practice and narrative order of a single human life is readily applicable but due to MacIntyre's profound criticism of capitalism, the notion of tradition is more difficult to incorporate comprehensively.

description: Background Enterococci are frequent pathogens causing nosocomial infections in Germany. Infections due to strains with vancomycin resistance are high when compared with other European states. Therefore, the study aimed to describe the recent progression of nosocomial infections due to vancomycin-resistant enterococci (VRE) in Germany. Methods We analyzed data from two components of the German national nosocomial infection surveillance system for the period 2007–2016. For primary bloodstream infections (BSIs) and urinary tract infections (UTIs) we used data from intensive care units and for surgical site infections (SSIs) data from surgical departments. In a sensitivity analysis, we considered only data from participants that participated continuously from 2007 to 2016 (“core group”). We calculated proportions of VRE among all nosocomial enterococcal infections with 95% confidence intervals (95% CIs) and trends over time. A multivariable logistic regression was used to compare occurrence of VRE proportions among German federal states. Results Enterococcal infections from 857 ICUs and 1119 surgical departments were analyzed. On ICUs, the proportion of vancomycin resistance in enterococci causing nosocomial infections significantly increased for BSIs from 5.9 to 16.7% and for UTIs from 2.9 to 9.9%; for surgical site infections, the proportion of VRE increased from 0.9 to 5.2% (P

description: Introduction. Quantitative myocardial perfusion measurements using positron emission tomography (PET) can be improved by introducing diagnostic tracers at a constant rate of activity. 82Rb can be produced cost effectively by eluting a 82Sr/82Rb generator with saline; however, it exhibits an undesirable, but reproducible, activity rate variation. Previously, a threshold-comparison algorithm controlled saline flow through either generator or bypass line using an on/off valve, to simulate constant-activity elutions. Methods. In this work a mechanical system and control software is developed to control tracer infusion. The valve is cycled at 5Hz and its duty-cycle controlled by a predictive-corrective algorithm in order to reduce measurable activity rate fluctuations. Results. Precision increases (RMS error improves from >40% to ∼14%) as does the range of relative activities that can be eluted from the generator. Conclusion. The proposed method demonstrates superior precision and flexibility. However, further tests must be conducted to ensure that the precision of the system does not deteriorate over time.

Words on one list were all of a high frequency (100 or more occurrences per million). Words on the other list occurred only from one to ten times per million on the Thorndike-Lorge word frequency list. Rates of verbal perseveration, number of correct responses and response latencies were examined on the two lists. The only significant difference was found on the number of correct responses. Subjects made more errors on the low frequency list. This conforms with prior results noted in the literature. The lack of significant difference for response latencies was contrary to prior findings. These results may have been due to a higher number of "no responses" on the low frequency list, and the quickness with which misperceptions of words were given. Only two subjects perseverated at all on either list. The low abstraction of the words and the lack of switching from one level of word difficulty to another were possible explanations for the results. Subjects were given the Boston Diagnostic Aphasia Examination and the Wide Range Achievement Test - Reading. The occurrence of perseveration on these tests was examined and classified. Two broad types of perseveration were noted (as well as 15 sub-categories). One type was of an intrusive nature whereby past responses interfered with or impinged on new responses, whether they be verbal or motor. The other was a form of modified responding which served an adaptive purpose. Correlations were calculated on the number of perseverative errors made on seven sub-tests of the Boston and the Wide Range Achievement Test - Reading. Significant positive correlations were found between three tests involving naming tasks. This was probably due to their similarity in nature. A significant negative correlation existed between the Wide Range Achievement Test - Reading and one of the naming tests. Perseveration tests have usually been found to have low positive correlations, sometimes reaching significance.

description: Urticaria (hives) is a common disorder that often presents with angioedema (swelling that occurs beneath the skin). It is generally classified as acute or chronic. Second-generation, non-sedating, non-impairing histamine type 1 (H1)-receptor antihistamines represent the mainstay of therapy for both acute and chronic urticaria. Angioedema can occur in the absence of urticaria and can be broadly divided into histamine-mediated and non-histamine-mediated angioedema. Histamine-mediated angioedema can be allergic, pseudoallergic or idiopathic. Non-histamine mediated angioedema is largely driven by bradykinin and can be hereditary, acquired or drug-induced, such as with angiotensin-converting enzyme inhibitors. Although bradykinin-mediated angioedema is often self-limited, laryngeal involvement can lead to fatal asphyxiation. The mainstay of management for angioedema is to avoid specific triggers, if possible. For hereditary angioedema, there are specifically licensed treatments that can be used for the management of acute attacks, or for prophylaxis in order to prevent attacks. In this article, the authors will review the causes, diagnosis and management of urticaria (with or without angioedema) and isolated angioedema. The diagnostic and therapeutic approaches to these two conditions are considerably different, and this review is designed to highlight these differences to the reader.

description: Background. The aim of the present study was to evaluate the effectiveness of a worksite multicomponent health promotion intervention on eating behavior and attitudes, changes in body weight, and readiness to make eating behavior changes among workers over a 12-month intervention period. Method. A total of 3,095 workers of a logistic company participated in a quasi-experimental comparison group study design. The intervention group received a multicomponent health training. Two of the main elements of the multicomponent intervention were physical exercise training and nutrition counseling/training. During the pilot year, participants completed a survey at baseline and again after 12 months to assess physical activity–, health-, and diet-related factors. Results. Results showed that participants’ body weight did not significantly decrease in the intervention group. Mean weight loss in the intervention groups was 0.5 kg (body mass index = 0.1 kg/m2). Eating behaviors in the intervention group improved more than in the comparison group. Some positive intervention effects were observed for the cognitive factors (e.g., changes in eating attitudes). Baseline readiness to change eating behavior was significantly improved over time. Conclusions. We demonstrated initial results of a long-term multicomponent worksite health promotion program with regard to changes in body weight, eating behavior, and attitudes. This evaluation of a 12-month pilot study suggests that a worksite health promotion program may lead to improvements in nutritional health behaviors for a number of workers. An investigation of long-term effects of this multicomponent intervention is strongly recommended.

L'évaluation de la formation : mise à l'épreuve de la relation entre les niveaux du modèle de Kirkpatrick.

description: The Public Service has undergone widespread reorganizations which have had a considerable impact on human resources and, in order to achieve a continuity of services, the employees have been required to take training courses. Consequently, there has been a marked increase in popularity for courses of short duration and these courses are becoming more profitable from the economic point of view. Are they, however, in terms of the pedagogy? The evaluation of the courses given by Training and Development Canada relies on the Kirkpatrick's training program evaluation model. This model proposes the evaluation of training at four levels: (1) reaction, (2) learning, (3) behavior and (4) results. Kirkpatrick claims the existence of a positive relationship between these levels. The development of measuring tools has allowed for the measurement of the first three levels of the model for four selected courses. By using a sample of 77 federal public servants, the assumption of a positive relationship has been established, with the help of correlation coefficients, for the Orientation to Financial Management course. However, this assumption has not been established for the courses Negotiating Skills, Effective Presentations and Writing Memos and Letters.

description: We present calibrations for star formation rate (SFR) indicators in the ultraviolet, mid-infrared, and radio-continuum bands, including one of the first direct calibrations of 150 MHz as an SFR indicator. Our calibrations utilize 66 nearby star-forming galaxies with Balmer-decrement-corrected H alpha luminosities, which span five orders of magnitude in SFR and have absolute magnitudes of -24 < M-r < -12. Most of our photometry and spectrophotometry are measured from the same region of each galaxy, and our spectrophotometry has been validated with SDSS photometry, so our random and systematic errors are small relative to the intrinsic scatter seen in SFR indicator calibrations. We find that the Wide-field Infrared Space Explorer W4 (22.8 mu m), Spitzer. 24 mu m, and 1.4 GHz bands have tight correlations with the Balmer-decrement-corrected Ha luminosity, with a scatter of only 0.2 dex. Our calibrations are comparable to those from the prior literature for L* galaxies, but for dwarf galaxies, our calibrations can give SFRs that are far greater than those derived from most previous literature.

description: The anthropogenic nitrogen cycle is characterized by a high complexity. Different reactive nitrogen species (NH3, NH4+, NO, NO2, NO3-, and N2O) are set free by a large variety of anthropogenic activities and cause numerous negative impacts on the environment. The complex nature of the nitrogen cycle hampers public awareness of the nitrogen problem. To overcome this issue and to enhance the sensitivity for policy action, we developed a new, impact-based integrated national target for nitrogen (INTN) for Germany. It is based on six impact indicators, for which we derived the maximum amount of nitrogen losses allowed in each environmental sector to reach related state indicators on a spatial average for Germany. The resulting target sets a limit of nitrogen emissions in Germany of 1053 Gg N yr-1. It could serve as a similar means on the national level as the planetary boundary for reactive nitrogen or the 1.5 ˚C target of the climate community on the global level. Taking related uncertainties into account, the resulting integrated nitrogen target of 1053 Gg N yr-1 suggests a comprehensible INTN of 1000 Gg N yr-1 for Germany. Compared to the current situation, the overall annual loss of reactive nitrogen in Germany would have to be reduced by approximately one-third. © 2021 by the authors
