Desert locusts are guided by olfactory cues in different behavioural contexts. In order to understand the basis for the variable olfactory guided behaviour displayed by different developmental stages and by solitary and gregarious locusts, we investigated their central olfactory system with neuroanatomical and neurophysiological methods. The primary olfactory centre of the brain, the antennal lobe

AIM: To investigate whether perinatal events, intrauterine or postpartum, are associated with the development of primary sclerosing cholangitis (PSC) later in life. METHODS: Birth records from 97 patients with adult PSC in Sweden were reviewed. Information on perinatal events including medications and complications during pregnancy, gestation length, birth weight and length were collected. Two con

The effects of salt, temperature, and deuterium oxide on the self-aggregation of n-tetradecyl-beta-D-maltoside (C(14)G(2)) in dilute solution have been investigated by static light scattering, dynamic light scattering (DLS), small-angle neutron scattering (SANS), tensiometry, and capillary viscometry. SANS data show that the micelles can be described as relatively flexible polymer-like micelles wi

Popular Abstract in Swedish Den kanske viktigaste anledningen till att söka en grundläggande förståelse av ekonomiskt beteende är att erhålla ett underlag för utformningen och genomförandet av ekonomisk politik. Utan en sådan förståelse minskas möjligheterna att uppnå målen för den ekonomiska politiken. Detta gäller i synnerhet den ekonomiska politik som bedrivs genom finanspolitik. En av finanspIn the first essay of this thesis, we examine whether the effects of fiscal expansions and contractions exert a symmetric influence on the relationship between fiscal policy and private consumption. Our results indicate a considerable asymmetry across fiscal expansions and contractions. More specifically, during fiscal contractions, transfers seem to influence private consumption in a neoclassical

This paper includes species investigated through many years starting with original material from museum collections. A great number of species in the genera Stephanodiscus Ehrenberg, Cyclostephanos Round and Cyclotella (Kutzing) Brebisson, all in the family Stephanodiscaceae Makarova, are presented with holo-, lecto- and/or neotypes, type locality and information concerning nomenclature. A typus g

Nanoplastics have been proven to induce toxicity in diverse organisms, yet their effect on soil microbes like bacteria and fungi remains largely unexplored. In this paper, we used micro-engineered soil models to investigate the effect of polystyrene (PS) nanospheres on Pseudomonas putida and Coprinopsis cinerea. Specifically, we explored the effects of increasing concentrations of 60 nm carboxylat

Relationships between cytosolic free calcium ([Ca2+]i) in platelets, indices of systemic calcium metabolism and blood pressure were examined in 86 subjects; 29 patients with untreated and 29 patients with treated essential hypertension, six patients with borderline hypertension and 22 healthy reference subjects. In order to analyse interactions between the variables, multivariate statistical analy

Background: We have previously performed a Genome Wide Association and linkage study that indicated a new disease triggering mechanism involving amino acid metabolism and nutrient sensing signaling pathways. Objective: The aim of this study was to investigate if plasma amino acid levels differed among children with celiac disease compared with disease controls. Materials and methods: Fasting plasm

Purpose: Manufacturer specifications for the resolution of an additive manufacturing (AM) machine can be ten times smaller (more optimistic) than the actual size of manufacturable features. Existing methods used to establish a manufacturable design rule-set are conservative piecewise-constant approximations. This paper aims to evaluate the effectiveness of a first-order model for producing improve

Jordens plattektoniska rörelser leder till tektoniska skeenden vid plattgränserna, bland annat bergskedjebildning, då berggrunden utsätts för förändringar i tryck och temperatur. Vid ändrat tryck och ändrad temperatur förändras också bergarter: de ursprungliga mineralen konsumeras i kemiska reaktioner och i stället bildas nya mineral som är stabila vid de nya fysikaliska förhållandena - en processDating of metamorphic events is crucial for the understanding and reconstruction of large-scale geological processes such as orogenesis. Zircon is one of the most commonly used minerals for dating of igneous and metamorphic events. Zircon incorporates uranium and excludes lead during crystallization, and with time the uranium decays to lead. The diffusion rates of both elements are slow, making zi

Objectives: To investigate survival among elderly residents of Swedish nursing homes (NHs), with specific focus on those with two or more signs of Lewy body dementia (LBD). Design: Prospective observational study. Setting: NHs in Malmö, the third largest city in Sweden. Participants: The study population was older adults (aged ≥65 years) living in the 40 NHs in Malmö. Clinical data were collected

Introduction: The purpose of this study was to investigate potential associations between body composition and current smoking in young healthy women from high-risk families. Cigarette smoke contains >7000 chemicals of which 69 are established carcinogens and smoke also acts as an aromatase inhibitor. Smoking is now recognized as a carcinogen for the breast and influences both risk and prognosis.

Argon, krypton, xenon, carbon, nitrogen, sulfur, and phosphorus have all been measured and found to be enriched by a quasi uniform factor in the 2-4 range, compared to their protosolar values, in the atmosphere of Jupiter. To elucidate the origin of these volatile enrichments, we investigate the possibility of an inward drift of particles made of amorphous ice and adsorbed volatiles, and their abi

While biometric authentication for commercial use so far mainly has been used for local device unlock use cases, there are great opportunities for using it also for central authentication such as for remote login. However, many current biometric sensors like for instance mobile fingerprint sensors have too large false acceptance rate (FAR) not allowing them, for security reasons, to be used in lar

Cold atmospheric plasma (CAP) has been demonstrated to be a successful antiseptic for chronic and infected wounds. Although experimental work has focused on elucidation of the curative power of CAP for wound healing, the molecular mechanisms behind this ability are less understood. To date, the direct effect of CAP on the activity of microbial virulence factors has not been investigated. In the pr

Temperaturändringar och krympning påverkar betongkonstruktioners volym, och i konstruktioner som hindras från av röra sig kan sådana volymändringar leda till så kallade tvångseffekter, som i sin tur kan orsaka sprickbildning. När detta sker kan emellertid konstruktionen deformeras till viss del, vilket gör att tvångsspänningarna och därmed också sprickvidderna minskar. Uppsprickningsförloppet är sThermal actions and shrinkage cause volume changes in concrete structures. In structures which are restrained from movements, the restraint effects can cause cracking. However, when cracking occurs, the structure can deform to some extent, which reduces the restraint stresses and thus also the crack widths. As the exact crack development is hard to predict beforehand, the actual restraint and thus

Objectives This study aimed to investigate the importance of potentially inappropriate medications, number of medications and chronic conditions for the risk of hospitalisation among an elderly population. Design This is a case-control study. Setting Population-based study in 2013 of all individuals aged 75 years and older (17 203) in the county of Blekinge in the southeast of Sweden. Participants
