Feasibility of Offshore Co-culture of Abalone, Haliotis discus hannai Ino, and Sea Cucumber, Apostichopus japonicus, in a Temperate Zone
No full textFeasibility of offshore co-culture of abalone and sea cucumber was investigated in Northern China. Survival and growth of abalone, Haliotis discus hannai Ino, and sea cucumber, Apostichopus japonicus, co-cultured in abalone cages from suspended longlines, in the offshore area, were examined. Abalone and sea cucumbers were co-cultured at density ratios of both 3: 1 and 6: 1 for 1 yr. Abalone were fed with fresh kelp and no additional feed was given to sea cucumbers. Survival of abalone and sea cucumber was 100% for all treatments. Abalone and sea cucumber grew well; the body weight (BW) of abalone and sea cucumber was nearly doubled and had reached a commercial size. There were no significant differences in the growth rates for both abalone and sea cucumber between the two density treatments. The specific growth rate of BW of abalone (SGRbw) was highest in June, with a value of 0.536%/ d. Growth rate of sea cucumber (SGRsc) was highest in December, reached 1.84%/ d, with an annual average SGRsc of 0.182%/ d. Results suggested that the offshore co-culture of abalone and sea cucumber was feasible offshore. The co-culture of abalone with sea cucumbers may provide an additional valuable crop without additional financial input.Feasibility of offshore co-culture of abalone and sea cucumber was investigated in Northern China.

The genome sequence of the lesser marbled fritillary, Brenthis ino, and evidence for a segregating neo-Z chromosome
No full textThe lesser marbled fritillary, Brenthis ino (Rottemburg, 1775), is a species of Palearctic butterfly. Male Brenthis ino individuals have been reported to have between 12 and 14 pairs of chromosomes, a much-reduced chromosome number than is typical in butterflies. Here, we present a chromosome-level genome assembly for Brenthis ino, as well as gene and transposable element annotations. The assembly is 411.8 Mb in length with a contig N50 of 9.6 Mb and a scaffold N50 of 29.5 Mb. We also show evidence that the male individual from which we generated HiC data was heterozygous for a neo-Z chromosome, consistent with inheriting 14 chromosomes from one parent and 13 from the other. This genome assembly will be a valuable resource for studying chromosome evolution in Lepidoptera, as well as for comparative and population genomics more generally
Six-proposition manifesto for small Island territories
No full textConventional wisdom suggests that small, often island, states are more likely than larger nations to be hard hit by the effects of national disasters, of fluctuations in the global economy, and the political aspirations of world powers. The structural weaknesses they share have been quantified to create a Vulnerability Index. This paper points to what the author sees as flaws in the concept of vulnerability and its application to the weaknesses of small states. In particular he presents evidence that small developing countries have performed no worse than larger countries. He sets out six propositions which explain this paradox and identifies the comparative advantages that small states hold.peer-reviewe

Association between nitric oxide treatment and intraventricular hemorrhage among extremely preterm neonates in Switzerland, 2012-2020.
No full textInhaled nitric oxide (iNO) treatment is routinely used to treat newborns suffering from severe respiratory distress syndrome (RDS). While the treatment is established for term born infants, its safety and efficacy remain controversial among preterm born infants. A 2017 meta-analysis focusing on this population reported a nonsignificant increase in the occurrence of severe intraventricular hemorrhage (sIVH) if infants were treated with iNO. sIVH is a dreaded complication of extreme premature birth that impairs long-term neurodevelopment. In this study, we hypothesize that iNO treatment is associated with the occurrence of sIVH among extremely preterm born infants. We investigated the Swiss population of infants born extremely preterm (< 28 weeks gestation) from 2012-2020 in a retrospective manner. The association between the treatment and sIVH was investigated by multivariable logistic regression analysis. A sensitivity analysis was performed by stratifying of the population according to the presence or absence of pulmonary hypertension of the newborn (PPHN). A total of 2101 neonates were included in the study. Among 251 patients in whom iNO treatment was applied, 62 (24.7%) suffered from sIVH, compared to 232 of the 1850 (12.5%) patients without iNO. We found no significant association between iNO treatment and the occurrence of sIVH in the presence of PPHN. It remains unclear whether the treatment is associated with the occurrence of sIVH in the absence of PPHN.Trial registration number: BASEC-ID 2022-00,403.© 2025. The Author(s)
Coherent flux tunneling through NbN nanowires
No full textWe demonstrate evidence of coherent magnetic flux tunneling through superconducting nanowires patterned in a thin highly disordered NbN film. The phenomenon is revealed as a superposition of flux states in a fully metallic superconducting loop with the nanowire acting as an effective tunnel barrier for the magnetic flux, and reproducibly observed in different wires. The flux superposition achieved in the fully metallic NbN rings proves the universality of the phenomenon previously reported for InO x . We perform microwave spectroscopy and study the tunneling amplitude as a function of the wire width, compare the experimental results with theories, and estimate the parameters for existing theoretical models.QN/Quantum NanoscienceApplied Science

Transferring the IKEA Culture: Co-creating a strategic intervention that allows IKEA employees to adopt the company culture
No full textEvery company has its own unique work-culture. Famous furniture seller IKEA, being no different. IKEA is currently active in 52 countries and is still growing strongly, so more and more people of different cultures are coming together because of it. IKEA’s culture has been formed through out the years and has the potential to help achieve great things. However, the IKEA sales coworkers do not have an incentive, nor the time to deepen their knowledge about the IKEA culture and its values. They therefore do not identify with it and do not use it in their every workday actions. This is bad for the IKEA brand and reduces the chances of company success. The IKEA culture is designed at the inter IKEA office, but has a different result on the actual work-floor. In order to bridge that gap, this report takes a unique bottom up-approach, while at the same time maintaining a top-down view. This is achieved by creating solutions for and together with the IKEA sales employees, while keeping the global view of the IKEA office in mind, and is supported by the fact that I (the author) am one of the very few coworkers at IKEA, that has worked in the store and at the office at the same time. Providing me with the opportunity to take the role of both main stakeholders; the end-users (the store coworkers) and the client (the IKEA franchisor). A work-culture is the result of employees living the company's key values in combination with their personal values. It is shaped by stories, artefacts, routines, rituals and symbols. All of which are researched through out this project. After the research grounded in literature, a lot of field research was also done. The main conclusions being that the current knowledge of culture was lacking among IKEA coworkers (for example; only 12 out of the 85 participants could say how many key values IKEA has), that the introduction of new coworkers would be the moment of intervention and lastly, that the intervention can have the biggest impact on sales employees. To support the bottom-up approach a thorough co-creation process took place. Lots of ideas were created in this session. They were clustered and detailed and eventually formed the inspiration behind three concepts; a strategic monthly intervention that addresses all key values, a board game that introduces those values and strategically designed ritual of introducing new coworkers to the IKEA culture. The concepts were presented to IKEA and all of the reactions were very positive, so a final concept was detailed. The final intervention revolves around the moment the new coworker receives his/her coworker uniform and consists of four parts: 1. the story the manager will tell the new coworker, 2. a key values box, 3. the new design of the IKEA clothing, with the key values printed on the inside, 4. a letter for inside the box. For each part a list of design criteria and design examples were given. The intervention can be tested at IKEA Delft, but has the potential to scale up to international levels. It has the opportunity to bring people from all over the world together under a common goal and to, in the end, create a better everyday life for the many people.Strategic Product Desig
