For years, it is an actuality in the poultry processing industry, that the body and the cardiovascular system of the chickens are not strong enough due to the shortened rearing time. This induces, that the quality of the chicken breast is not appropriate for selling, since during the processing procedure, frequently blood spots appear inside the meat. These damaged parts need to be removed, causin

As urban systems continue to grow worldwide, urban peripheries increase in number and typologies, which makes their planning a challenge for sustainable development. The aim of this article is to explore approaches and challenges related to the application of sustainable planning to urban peripheries. We reviewed the content of 102 papers related to sustainable planning in urban peripheries by app

This chapter focuses on a specific kind of governance namely sustainability governance. Combatting climate change and social inequalities calls for governance systems specifically directed to corporate sustainability. Today our companies are fiercely working on setting up efficient systems for sustainability governance. In this chapter, the reader will learn what a sustainability governance system

Clock synchronization is a necessary component in modern distributed systems, especially WSN. Despite the great effort and the numerous improvements, the existing synchronization schemes do not yet address the cancellation of propagation delays. Up to a few years ago, this was not perceived as a problem, because the time-stamping precision was a more limiting factor for the accuracy achievable wit

The immune system is the main defense barrier against infections but exerts selection pressures on other life history traits. Recent studies have given importance to understanding the role of the immune system in birds, and it has been hypothesized that during migration, birds either increase their immune function, as they might encounter novel pathogens, or decrease it to account for the cost of

OBJECTIVE: Screening for abdominal aortic aneurysm (AAA) using ultrasound in men reduces aneurysm-related mortality. Ambulatory screening and surveillance procedures facilitated by point-of-care ultrasound (POCUS) may improve adherence to screening programs. This proof-of-concept study evaluated whether infrarenal aortic diameter (IAD) can be accurately and interchangeably measured using handheld

In a recent paper, Miguel Sebastián has posed an objection to the higherorder thought theory of consciousness. The higher-order thought theory of consciousness holds that a mental state is conscious when it is the intentional object of a higher-order thought (HOT). Often, the HOT is conceived to be essentially indexical. This means that the HOT somehow picks out the individual who tokens it. Sebas

The multifunctionality of forest systems calls for appropriately complex modelling approaches to capture social and ecosystem dynamics. Using a social-ecological systems framework, we review the functionality of 31 existing agent-based models applied to managed forests. Several applications include advanced cognitive and emotional decision-making, crucial for understanding complex sustainability c

The paper combines a truthmaker semantics with a dispositional view of beliefs according to which they are dispositions of agents to act as if truthmakers obtain. This has a number of virtues in that it gives us (i) an exact semantics for belief reports; as well as plausible accounts of both (ii) epistemic closure and (iii) contradictory beliefs. In particular, it allows us to analyze knowledge in

Peatlands, with high spatial variability in ecotypes and microforms, constitute a significant part of the boreal landscape and play an important role in the global carbon (C) cycle. However, the effects of this peatland heterogeneity within the boreal landscape are rarely quantified. Here, we use field-based measurements, high-resolution land cover classification, and biogeochemical and atmospheri

The cause of massive blooms of Ethmodiscus rex laminated diatom mats (LDMs) in the eastern Philippine Sea (EPS) during the Last Glacial Maximum (LGM) remains uncertain. In order to better understand the mechanism of formation of E. rex LDMs from the perspective of dissolved silicon (DSi) utilization, we determined the silicon isotopic composition of single E. rex diatom frustules (δ30SiE. rex) fro

During host colonization, bacteria use the alarmones (p)ppGpp to reshape their proteome by acting pleiotropically on DNA, RNA, and protein synthesis. Here, we elucidate how the initiating ribosome senses the cellular pool of guanosine nucleotides and regulates the progression towards protein synthesis. Our results show that the affinity of guanosine triphosphate (GTP) and the inhibitory concentrat

Media scandals is one of the areas within the media field with high passion potential. The emotions within politics, that otherwise may be covered by rational arguments and cultural codes, are often in full bloom when a scandal takes place on the political scene (which as we know is a mediated scene). However, after a few decades of media scandal-research, a scientific convention seems to have ari

The binocular field of vision differs widely in birds depending on ecological traits such as foraging. Owls (Strigiformes) have been considered to have a unique binocular field, but whether it is related to foraging has remained unknown. While taking into account allometry and phylogeny, we hypothesized that both daily activity cycle and diet determine the size and shape of the binocular field in

We present here the genomic structures for two genes implicated in craniofacial development. Retinoic acid receptor alpha (RARA), or a gene in its vicinity, has been implicated in non-syndromic cleft lip and palate, based on both association and linkage studies. Using primers directed to the 3' -UTR of the published cDNA sequence, we screened a human genomic BAC library to obtain a clone containin

On-chip enzyme reactors are often used in medical/pharmaceutical analysis due to their inherent advantages, such as high sample throughput, low reagent consumption, stability, reproducibility and low cost. The present work describes a different application of such microreactors, namely, elimination of interfering ascorbate signals in glutamate monitoring using ascorbate oxidase modified silicon ch

Popular Abstract in Swedish Syftet med denna studie är att försöka förklara varför araméen Laban, vilken i Bibeln (Genesis) framstår som en ganska harmlös bifigur, i rabbinsk litteratur i allmänhet betraktas som en av Jakobs och därmed Israels stora fiender. Avhandlingen hävdar att bilden av Laban som en skurk utvecklats som ett resultat av rabbinsk hermeneutik och att de egenskaper som tillskrivsThis study attempts to answer the question of why Laban the Aramean, a rather harmless character as presented in the biblical text, is generally portrayed in rabbinic literature as a major enemy of Jacob and Israel. It is argued that the portrait of Laban as a villain developed as a result of rabbinic hermeneutics, and that the characteristics which are attributed to him in rabbinic literature wer

Popular Abstract in Swedish Elektrostatiske vekselvirkninger mellem biomolekyler er vigtige, ikke bare i biologiske systemer, men også i flere tekniske sammenhænge. I denne afhandling studereres en række forskellige egenskaber, relevant for særligt proteiner. Således har vi ved hjælp af molekylær simulering undersøgt hvorledes proteiner vekselvirker med protoner, salte, andre peptider og proteinerElectrostatic interactions in bio-molecular systems are important not only in the living cell but also in more technical applications. Using molecular simulation as well as approximate theories the properties of a number of aqueous protein solutions have been studied. This includes interactions with other proteins, protons, charged membranes as well as flexible polyelectrolytes. The focus is on el

From its early days, the academic debate on public goods has focused on discrepancies or trade-offs regarding the provision of public goods on the one hand and private goods on the other. However, both the extension of the public domain and an increasing interdependence in international relations clearly drive the expansion of an agenda in which there are a growing number of cases where public goo
