- Purpose of this paper The purpose of this paper is to explore the role and potential of packaging in order to obtain more sustainable goods flows. Design/methodology/approach An explorative research approach based on case survey methodology in which description, exploration and analysis of 34 reported cases are made. The empirical focus is goods flows in fast moving consumer goods (FMCG) supply chains. Findings The insights presented highlights and provides guidance on the pros and cons packaging provides for sustainable goods flows in the FMCG industry. Research limitations/implications (if applicable) Based on knowledge and insights about the flows of goods and tomorrows requirements on sustainable societies, this paper reports on insights for making the goods flows in the FMCG industry sustainable based on a packaging perspective. The research has focused on FMCG goods flows, starting with the inbound flow of packaging at the product filler and ending at the retail outlet. Practical implications (if applicable) The insights can guide organisations to consider and reflect on how and when packaging enables or hinder sustainability aspects of goods flows. Extra effort should be on designing packaging system solutions that mitigate the negative effects of non-consumed products. What is original/value of paper While several studies have reported on the sustainability impact of logistics, transportation or supply chain structures, the perspective of packaging is rarely treated, neither in theory nor in practise. With a packaging perspective, the assessment of goods flows in supply chains is integrative, since packaging is naturally built on the intersection of logistics, marketing, sales, ergonomics and environmental considerations.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Förpackningar ses ofta som en belastning för miljön och något ont som ska minimeras. Ny forskning visar att det tvärtom finns tillfällen då det är motiverat att öka mängden förpackningsmaterial, exempelvis när man kan minska spillet. Tvärvetenskapligt framtagna sätt att förpacka varor kan bidra till en hållbar utveckling och öka marginalerna för handeln. Nyckeln till effektiva varuflöden är välfyllda lastytrymmen och välanpassade förpackningssystem.

- Pituitary neuroendocrine tumors (PitNETs) are common, generally benign tumors with complex clinical characteristics related to hormone hypersecretion and/or growing sellar tumor mass. PitNETs can be classified based on the expression pattern of anterior pituitary hormones and three main transcriptions factors (TF), SF1, PIT1 and TPIT that regulate differentiation of adenohypophysial cells. Here, we have extended this classification based on the global transcriptomics landscape using tumor tissue from a well-defined cohort comprising 51 PitNETs of different clinical and histological types. The molecular profiles were compared with current classification schemes based on immunohistochemistry. Our results identified three main clusters of PitNETs that were aligned with the main pituitary TFs expression patterns. Our analyses enabled further identification of specific genes and expression patterns, including both known and unknown genes, that could distinguish the three different classes of PitNETs. We conclude that the current classification of PitNETs based on the expression of SF1, PIT1 and TPIT reflects three distinct subtypes of PitNETs with different underlying biology and partly independent from the expression of corresponding hormones. The transcriptomic analysis reveals several potentially targetable tumor-driving genes with previously unknown role in pituitary tumorigenesis.

- AIM: Extremely premature infants receive nutrition and medication through nasogastric tubes. Breastmilk given accordingly is subject to fat loss. This study aimed to investigate whether this could also apply to vitamin D.METHODS: A questionnaire investigated vitamin D administration at a level III neonatal intensive care unit in Sweden in 2021. Feeding simulations with breastmilk and various vitamin D mixtures were done accordingly. After administration, vitamin D3 concentration was analysed using chromatography with mass spectrometry, followed by repeated simulations with vitamin D mixtures without breastmilk in 2023.RESULTS: The questionnaire was completed by 10 persons. Vitamin D was administered as drops using an enteral syringe and a nasogastric tube in conjunction with a breastmilk meal. In the feeding simulations, vitamin D3 concentration after administration was significantly higher using a syringe alone compared to standard administration. When vitamins were administered according to standard but without breastmilk, 100% of the vitamin D and 40% of the multivitamins were lost. The vitamins adhered to the material, mainly in the nasogastric tube.CONCLUSION: Our findings indicate that standard vitamin D supplementation in the neonatal intensive care unit may be unpredictable when administered by enteral syringe and nasogastric tube. We suggest using direct oral administration whenever possible.

- Radiological imaging to examine intracranial blood vessels is critical for preoperative planning and postoperative follow-up. Automated segmentation of cerebrovascular anatomy from Time-Of-Flight Magnetic Resonance Angiography (TOF-MRA) can provide radiologists with a more detailed and precise view of these vessels. This paper introduces a domain generalized artificial intelligence (AI) solution for volumetric monitoring of cerebrovascular structures from multi-center MRAs. Our approach utilizes a multi-task deep convolutional neural network (CNN) with a topology-aware loss function to learn voxel-wise segmentation of the cerebrovascular tree. We use Decorrelation Loss to achieve domain regularization for the encoder network and auxiliary tasks to provide additional regularization and enable the encoder to learn higher-level intermediate representations for improved performance. We compare our method to six state-of-the-art 3D vessel segmentation methods using retrospective TOF-MRA datasets from multiple private and public data sources scanned at six hospitals, with and without vascular pathologies. The proposed model achieved the best scores in all the qualitative performance measures. Furthermore, we have developed an AI-assisted Graphical User Interface (GUI) based on our research to assist radiologists in their daily work and establish a more efficient work process that saves time.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Seglet är ett 12-vånings punkthus med 44 lägenheter beläget i Karlstad. Byggherre är Karlstads Bostads AB. Huset är byggt med mycket höga ambitioner när det gäller kvalitet och resurshushållning och togs i drift i börjanav 2007.Denna rapport redovisar klimatskalets egenskaper och funktion samt utformningen av installationssystemen för värme, ventilation och tappvatten.Rapporten beskriver också drifterfarenheterna från de första årens drift samt de förbättringsåtgärder som utförts.Seglets lösningar visar att energieffektivisering och inneklimat kan gå hand ihand. Konceptet med en enkel förvärmning av tilluften löser två problem. Dels kan tilluften tillföras lägenheten utan risk för drag och dels saknar det FTX-systemets nackdelar med utökat servicebehov för filterbyten och ökad elanvändning för tilluftsfläkten. Det välisolerade och täta klimatskalet ger en komfortabel inomhusmiljö. Den befarade risken med höga rumstemperaturer sommartid har inte besannats. Tack vare genomtänkta fönsterplaceringar med solskyddsglas där så är befogat samt goda möjligheter till effektiv vädring har lägenheterna samma temperaturnivå sommartid som motsvarande lägenheter i normalisolerade byggnader. Byggnaden är mycket resurseffektiv med låga förbrukningstal på både energi och vatten. Då största delen av värmebehovet täcks med fjärrvärme står sig byggnaden mycket väl i en jämförande miljöbedömning.Nyckeltal för klimatskal och energianvändningMedelvärde för klimatskalets värmeisolering, Um, W/m2,K ca 0,21Luftläckage, läckflöde vid provtryckning till 50 Pa, l/s,m2Aomg 0,13Specifik energianvändning, kWh/m2,år 58

- Temperature control is important for the steel making process. Knowledge of the amount of thermal energy stored in the ladle allows for better predictions of the steel temperature during the process. This has a potential to improve the quality of the steel. In this work, we present a mathematical model of the heat transfer within a ladle during the production process. The model can be used to compute the current, and also the future, thermal status of the ladle. The model is simple and can be solved efficiently. We also present results from numerical simulations intended to illustrate the model.
