TOLERANCE OF CEREALS TO POST- EMERGENCE WEED HARROWING

This study defines crop tolerance to post-emergence weed harrowing as the combined effect of crop resistance and crop recovery. Crop resistance is the ability of the crop to resist soil covering and recovery is the ability to recover in terms of yield. In two experiments, resistance, recovery and tolerance were quantified in barley, oat, wheat and triticale by a new method based on digital image analysis. Important differences in resistance, recovery and tolerance among species were seen and resistance was not linked to recovery. Oat showed higher resistance than wheat, and barley. Triticale showed the lowest resistance. Oat and barley showed both lower ability to recover from soil covering than wheat, and triticale showed complete recovery. Triticale was the most tolerant species followed by wheat, oat and barley. Differences in tolerance caused species dependent crop yield losses in weed-free environments in the range of 0 to 10% for a practical relevant aggressiveness of weed harrowing

Å ivareta barn på generell intensivavdeling – intensivsykepleieres erfaringer

Background: Intensive care nurses in general intensive care units must care for patients of all ages. Most Norwegian hospitals do not have a dedicated paediatric intensive care unit. Thus, acutely and critically ill children are cared for in the general intensive care unit, where there is a majority of adult patients. The children are in a particularly vulnerable situation. Their diagnoses and illnesses often differ from those of critically ill adult patients. Objective: To acquire insight into the perceptions and experiences of intensive care nurses when caring for acutely and critically ill children admitted to the general intensive care unit. Method: We used a qualitative, exploratory design. Two qualitative focus group interviews were conducted with altogether ten intensive care nurses employed in the general intensive care unit. A phenomenological hermeneutic research method was adopted. We analysed the data material using Graneheim and Lundman’s qualitative content analysis. Results: The analysis identified three themes: good preparation leads to safe treatment, cooperation in the child’s best interests, and relating to children according to their development stage. Each theme is illustrated by three to five categories. Conclusion: The study shows that the intensive care nurses generally felt positive about caring for children in the general intensive care unit, even though they had experienced feelings of insecurity and unease. Measures such as good training, good cooperation and fulfilling the child’s needs had enhanced their experiences.publishedVersio

The Coastal Reference Fleet 2007-2019 - Fleet composition, fishing effort and contributions to science

Catch quotas are used for the sustainable management of fish stocks and are based on official catch statistics and research surveysSustainable management of the Norwegian fisheries depends on quota advice that is based on stock assessments, using scientific data from research surveys and official landings statistics. The official landings statistics are given in metric tons, and for vessels less than 15 meters only include rough information on fishing effort. The research cruises, on the other hand, only take place in certain areas and at certain times of the year. However, these methods provide only partial information, as the official catch data at best include rough measures of effort, and the survey data are only collected at certain times of the year. In 2005, the Norwegian Coastal Reference Fleet (CRF) was established by the Institute of Marine Research (IMR) ,to obtain data at-sea on in order to register catches in numbers per species including size- and age composition, discards, and bycatch, as well as data on fishing , gear, and effort. The vessels in the CRF were selected along the entire coast using criteria to ensure that they as represent able for the Norwegian coastal fishing fleet as closely as possible. These historic data and the development of the CRF are evaluated have been ccomprehensively visualisedin , and this report, using descriptive methods and provides a description and visual displaysanalysis of the CRF data. Between 2007-2019, a total of 64 fishing vessels particip ated in the CRF along the Norwegian coast collecting data from a cumulated total number of 287 taxa, and from 29 137 individual fishing operations. The most common species was cod (Gadus morhua), which occurred in 60.9% of the fishing operations. Throughout the study period gillnet was the most common gear in all years, but there were small shifts in the gear composition over time of the CRF shifted, however gillnet was the most common gear in all years. Catch per unit effort (CPUE) from fisheries standardises catch data for comparisons in both space and time and is often used as a proxy indices of for fish abundance, assuming constant catchability (the probability from 0 to 1 of a fish being caught per unit effort) over time. When collecting fisheries dependent data, however, fishers actively try to maximise catchability of their target species or species composition, by e.g., using different gears to handle natural variations in catchability dependent on season, and area. Broad coverage in space and time may reduce this human bias as well as providing information on the behaviour of the fishers and the effect of technological advancements. This report includes CPUE timeseries for cod, haddock (Melanogrammus aeglefinus), and golden redfish (Sebastes norvegicus) north of 62°N.publishedVersio

Organic Food and Health: A new project to study the effects of plant cultivation methods (organic and conventional) on nutritional value, health and reproduction in an animal experiment

Many consumers believe that food from plants grown under certain conditions, such as organic agriculture, will benefit health more than conventional food. This cannot be determined simply by analysing the material, since our understanding of the connections between food components and health is still to imprecise for such a purpose. Rather than waiting until basic research provides the knowledge needed for this approach, in the spring of 2001 we have initiated a project to study physiological effects of plant quality directly, in an animal experiment. The following cultivation treatments are used to grow plants that are typical ingredients for a human diet (potato, mature peas, kale, spring wheat, oilseed rape, carrots and apples): 1. A model of a distinct conventional cultivation system, with high input of mineral nutrients and use of as much pesticides as is allowed. 2. A model of a distinct organic cultivation system, with low input of organic plant nutrients and no use of pesticides. 3. A combination of model 1 and 2, with low input of nutrients and use of pesticides. The materials from each cultivation treatment will be thoroughly characterised, by measuring contents of nutrients (protein, minerals, energy content, vitamins), the biological value of major protein sources of feed plants will be assessed, selected secondary metabolites including known anti-nutrients will be measured and other quality indicators will be assessed including biocrystallization. Based on these results, 3 feed mixtures will be prepared, either based on defined weight percentages of each material from each treatment, or, if large variation in biological value is found, one or two feed mixtures can be adjusted to provide the same availability of protein and energy as the reference treatment (model 1). Potato, mature peas and kale will be cooked and freeze-dried, wheat is ground and baked to biscuits, oil is produced from the rapeseed, and raw carrots and apples are shredded and freeze dried, before feed pellets with the desired composition are prepared from the material. Three groups of rats are each provided one of the dietary treatments during 2.5 generation, and reproductive characteristics and performance are recorded. Subgroups of the last generation are selected for an intensive study in which uptake and excretion of energy and protein and selected micronutrients are determined. Respiration trials are performed to assess the energy metabolism, and simultaneous measurements of the activity levels of the rats are performed. In addition, blood and tissue samples of the rats will be obtained to study the effect of the dietary treatments on the immunological and antioxidant status of the rats. Data from the experiments are assembled and analysed using relevant statistical models, and the relationship to the nutritional characteristics of the plant material is described. Funding for the core project for a 4-year period is secured from the Danish Research Centre for Organic Farming (DARCOF). However, the intention is to provide a platform for international collaboration, since the well-documented material of plants and animals can provide multiple opportunities for associated projects. To investigate other aspects of plant composition or health than what is foreseen in the present project, or to follow up on it with additional experiments

Health professionals’ knowledge about female genital schistosomiasis. A qualitative investigation in a schistosomiasis endemic area in South Africa

Female Genital Schistosomiasis (FGS) is a neglected tropical disease that affects the lives of millions of women living in endemic areas. The aim of this study was to identify South African healthcare professionals' perceptions and experiences of Female Genital schistosomiasis. This qualitative study took place in Ugu District, KwaZulu-Natal, South Africa, in one Community Health Centre and two Primary Health Care clinics. The purpose was to explore local healthcare professionals' views and knowledge on FGS in an area endemic for Schistosoma haematobium, referred to as bilharzia, or isichenene in isiZulu. The empirical findings collected through interviews and observations are discussed in relation to the well-established research on FGS. This project also took cognizance of the United Nations (UN) sustainability development goals (SDGs) with a focus on gender and sanitation, as well as control programmes to prevent schistosomiasis. The study showed that there was a multi-faceted gap in knowledge between local midwives and professional nurses’ work-related knowledge and the medical research team. Among the main causes are skewed power relations, whereby the women affected by FGS often have low socioeconomic status in society while the higher power structures do not prioritize FGS. This leads to health professionals being in a “middle position” where they are responsible for community health but are governed by their training and the guidelines of the institution in which they are a part. Furthermore, the study showed the importance of culture since nurses and midwives consult with patients, as they are part of a framework where their role is constrained due to governmental policies, protocols for patient care and the local culture. To provide adequate health services for FGS patients, this study indicates that policy, female patient management protocols, curricula, post graduate training, clinical practice and schistosomiasis prevention programs should include FGS.publishedVersio
