Salt content in herring – How the salt content in herring changes during capture and catch handling

Brazil applies a threshold limit value for the amount of salt that is accepted in natural herring, namely 134 mg sodium per 100 g fillet. Compared with the salt content values found in the relevant literature, and the measurements that are routinely performed in Norway, this is a low value that would be difficult to fulfil. RSW (Refrigerated Sea Water) is a quick and appropriate agent for chilling large catches – of herring, for example. However, when fish are stored in RSW after capture, they may assimilate salt from the cooling medium. Another factor that can increase the salt content in herring is stress. When herring are subjected to stress, as happens during capture, the salt content in their blood will increase. All in all, the threshold limit value set for salt content in Brazil is considered to be unrealistically low, taking into account how catches are handled in Norwegian pelagic fisheries. * The original report is in Norwegian and the reference is: 8/2023, ISBN 978-82-8296-743-3Salt content in herring – How the salt content in herring changes during capture and catch handlingpublishedVersio

New York Times Coverage of Presidential Campaigns

This study investigates New York Times coverage of the Democratic and Republican general presidential campaigns from 1952–2000. Content analysis reveals that the most common topic of campaign coverage was horse race. Discussion of the candidates' character was more common than discussion of their policy positions (even though candidates discuss policy more than character in campaign messages). The statements in these stories were more often negative than positive (despite the fact that candidates' messages are more positive than negative). Reporters are the most common sources for the statements in these articles, followed by candidates, supporters, and others.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

The Refractive Index Change in GaAs-AlGaAs Quantum Wells Produced by Neutral Impurity Induced Disordering Using Boron and Fluorine

This thesis is concerned with quantum well intermixing in GaAs-AlGaAs multiple quantum well structures due to the impurity induced disordering effect using the electrically neutral impurities boron and fluorine. Particular emphasis is put on the refractive index change induced by the disordering process, and on methods of implementing this technique in the development of novel semiconductor laser structures. Selective intermixing of quantum wells is a powerful tool in the quest for developing functional integrated photonic structures. The use of impurities to enhance the interdiffusion rate of group III materials in quantum wells and barriers in well defined regions enables the creation of regions with lower optical propagation loss (< 4.5 dBcm-1).This can be utilised in low-loss waveguides for optical interconnects, extended cavity lasers, high efficiency distributed Bragg reflector lasers and more. The introduction of the impurities used in IID leads to an increased interdiffusion rate of the group III materials in the III-V semiconductor quantum well structure when present in volume concentrations above a threshold value (?1018 cm-3) and when the structure is subjected to annealing at a temperature (e.g. 89

Reciprocal Ethics: _The Formal Science of Ethics_

Reciprocal Ethics is a novel ethical framework rooted in praxeology, the study of purposeful action. It represents an entirely new paradigm in moral philosophy, placing interaction at the core of universal ethics. Traditional ethical theories often divorce thought from action. Reciprocal Ethics contends that they are two aspects of the same phenomenon in the human experience, removing the traditional boundary between theoretical and practical ethics. The system categorizes all social interaction as either “self-directed” or “other-directed”, and by introducing the concept of "normative signaling" it also exerts legitimate prescriptive power. The theory is a self-consistent, purely descriptive approach to ethics, that suggests that one's actions serve as semiotic signs that signal one's ethical stance in social interaction. Hence actions do not only define individual moral profiles, but also the moral ecosystem within which one actually operates. The theory operates in real time, adapting to the complexity of reality by taking into account uncertainty, incomplete data and social asymmetries. Reconciling elements of consequentialism and deontological theories, Reciprocal Ethics delivers a streamlined, yet comprehensive ethical system for social interaction, offering tangible insights for navigating complex moral dilemmas. By synthesizing descriptive metaethics and normative moral philosophy into one comprehensive formal theory, a bold assertion arises: Reciprocal Ethics becomes the Formal Science of Ethics

Pelvic irradiation does not increase the risk of hip replacement in patients with gynecological cancer. A cohort study based on 8,507 patients

Background and purpose — Long-term survivors of cancer can develop adverse effects of the treatment. 60% of cancer patients survive for at least 5 years after diagnosis. Pelvic irradiation can cause bone damage in these long-term survivors, with increased risk of fracture and degeneration of the hip. Patients and methods — Analyses were based on linkage between the Cancer Registry of Norway (CRN) and the Norwegian Arthroplasty Register (NAR). All women who had been exposed to radiation for curative radiotherapy of gynecological cancer (40–60 Gy for at least 28 days) were identified in the CRN. Radiotherapy had been given between 1998 and 2006 and only patients who were irradiated within 6 months of diagnosis were included. The control group contained women with breast cancer who had also undergone radiotherapy, but not to the pelvic area. Fine and Gray competing-risk analysis was used to calculate subhazard-rate ratios (subHRRs) and cumulative incidence functions (CIFs) for the risk of having a prosthesis accounting for differences in mortality. Results — Of 962 eligible patients with gynecological cancer, 26 (3%) had received a total hip replacement. In the control group without exposure, 253 (3%) of 7,545 patients with breast cancer had undergone total hip replacement. The 8-year CIF for receiving a total hip replacement was 2.7% (95% CI: 2.6–2.8) for gynecological cancer patients and 3.0% (95% CI: 2.95–3.03) for breast cancer patients; subHRR was 0.80 (95% CI: 0.53–1.22; p = 0.3). In both groups, the most common reason for hip replacement was idiopathic osteoarthritis. Interpretation — We did not find any statistically significantly higher risk of undergoing total hip replacement in patients with gynecological cancer who had had pelvic radiotherapy than in women with breast cancer who had not had pelvic radiotherapy

Electronic Structures of LNA Phosphorothioate Oligonucleotides

Important oligonucleotides in anti-sense research have been investigated in silico and experimentally. This involves quantum mechanical (QM) calculations and chromatography experiments on locked nucleic acid (LNA) phosphorothioate (PS) oligonucleotides. iso-potential electrostatic surfaces are essential in this study and have been calculated from the wave functions derived from the QM calculations that provide binding information and other properties of these molecules. The QM calculations give details of the electronic structures in terms of e.g., energy and bonding, which make them distinguish or differentiate between the individual PS diastereoisomers determined by the position of sulfur atoms. Rules are derived from the electronic calculations of these molecules and include the effects of the phosphorothioate chirality and formation of electrostatic potential surfaces. Physical and electrochemical descriptors of the PS oligonucleotides are compared to the experiments in which chiral states on these molecules can be distinguished. The calculations demonstrate that electronic structure, electrostatic potential, and topology are highly sensitive to single PS configuration changes and can give a lead to understanding the activity of the molecules.

Kaplan-Meier and Cox Regression Are Preferable for the Analysis of Time to Revision of Joint Arthroplasty: Thirty-One Years of Follow-up for Cemented and Uncemented THAs Inserted from 1987 to 2000 in the Norwegian Arthroplasty Register

Background: Previous studies have suggested that the probability function of 1 minus the Kaplan-Meier survivorship overestimates revision rates of implants and that patient death should be included in estimates as a competing risk factor. The present study aims to demonstrate that this line of thinking is incorrect and is a misunderstanding of both the Kaplan-Meier method and competing risks. Methods: This study demonstrated the differences, misunderstandings, and interpretations of classical, competing-risk, and illness-death models with use of data from the Norwegian Arthroplasty Register for 15,734 cemented and 7,867 uncemented total hip arthroplasties (THAs) performed from 1987 to 2000, with fixation as the exposure variable. Results: The mean age was higher for patients who underwent cemented (72 years) versus uncemented THA (53 years); as such, a greater proportion of patients who underwent cemented THA had died during the time of the study (47% compared with 29%). The risk of revision at 20 years was 18% for cemented and 42% for uncemented THAs. The cumulative incidence function at 20 years was 11% for cemented and 36% for uncemented THAs. The prevalence of revision at 20 years was 6% for cemented and 31% for uncemented THAs. Conclusions: Adding death as a competing risk will always attenuate the probability of revision and does not correct for dependency between patient death and THA revision. Adjustment for age and sex almost eliminated differences in risk estimates between the different regression models. In the analysis of time until revision of joint replacements, classical survival analyses are appropriate and should be advocated.publishedVersio

Statistical criteria for characterizing irradiance time series.

We propose and examine several statistical criteria for characterizing time series of solar irradiance. Time series of irradiance are used in analyses that seek to quantify the performance of photovoltaic (PV) power systems over time. Time series of irradiance are either measured or are simulated using models. Simulations of irradiance are often calibrated to or generated from statistics for observed irradiance and simulations are validated by comparing the simulation output to the observed irradiance. Criteria used in this comparison should derive from the context of the analyses in which the simulated irradiance is to be used. We examine three statistics that characterize time series and their use as criteria for comparing time series. We demonstrate these statistics using observed irradiance data recorded in August 2007 in Las Vegas, Nevada, and in June 2009 in Albuquerque, New Mexico
