Visual acuity of the honey bee retina and the limits for feature detection

Visual abilities of the honey bee have been studied for more than 100 years, recently revealing unexpectedly sophisticated cognitive skills rivalling those of vertebrates. However, the physiological limits of the honey bee eye have been largely unaddressed and only studied in an unnatural, dark state. Using a bright display and intracellular recordings, we here systematically investigated the angu

Modeling of shear walls using finite shear connector elements based on continuum plasticity

Light-frame timber buildings are often stabilized against lateral loads by using diaphragm action of roofs, floors and walls. The mechanical behavior of the sheathing-to-framing joints has a significant impact on the structural performance of shear walls. Most sheathing-to-framing joints show nonlinear load-displacement characteristics with plastic behavior. This paper is focused on the finite ele

Constraining N2O emissions since 1940 using firn air isotope measurements in both hemispheres

N2O is currently the third most important anthropogenic greenhouse gas in terms of radiative forcing and its atmospheric mole fraction is rising steadily. To quantify the growth rate and its causes over the past decades, we performed a multi-site reconstruction of the atmospheric N2O mole fraction and isotopic composition using new and previously published firn air data collected from Greenland an

Mobility and Regionalisation : Changing patterns of air traffic in the Baltic Sea Region in connection to European Integration

The geo-political transition in 1989-91 had long term consequences for the European integration process. The integration and regionalisation processes following the transition resulted in a transformation of territorial borders in and around the region; the functions of the borders changed. Mobility is vital for these processes. This paper is based on a longitudinal study of the development of air

Infusional Therapies, Continuous Dopaminergic Stimulation, and Nonmotor Symptoms

Pump-based Parkinson (PD) therapies, including subcutaneous apomorphine infusion (CSA) and levodopa-carbidopa intestinal gel (LCIG), presently constitute the most effective pharmacological treatments available for advanced PD. These therapies are based on a more constant delivery of the dopaminergic drug resulting in a more continuous dopaminergic stimulation and a more stable treatment effect. Th

The Montreal Cognitive Assessment : Normative Data from a Large Swedish Population-Based Cohort

Background: The Montreal Cognitive Assessment (MoCA) has a high sensitivity for detecting cognitive dysfunction. Swedish normative data does not exist and international norms are often derived from populations where cognitive impairment has not been screened for and not been thoroughly assessed to exclude subjects with dementia or mild cognitive impairment. Objective: To establish norms for MoCA a

Pinning the slipped and contralateral hips in the treatment of slipped capital femoral epiphysis

Purpose To describe and comment on the treatment of the slipped capital femoral epiphysis (SCFE) with pinning and to present the pros and cons of prophylactic pinning of the contralateral hip. Summary Pinning the SCFE aims to fix the epiphysis and prevent further slipping. Some devices allow for further growth and remodeling of the femoral neck post-operatively. This results in maintained femoral

Tillgång till snabb laboratorieanalys vid akut förgiftning ger bättre och säkrare vård

The Swedish Poisons Information Centre, a nationwide 24/7 service to healthcare providers and the public, answers many questions about serious cases of acute poisoning. In some of these, prompt and proper treatment recommendations can be crucial for the clinical outcome. In cases where self-reported information is missing or considered unreliable, more emphasis is placed on the clinical symptoms a

Description of a reproducible anatomically based surgical algorithm for detection of pelvic sentinel lymph nodes in endometrial cancer

Objective: To describe and evaluate a reproducible, anatomically based surgical algorithm, including reinjection of tracer to enhance technical success rate, for detection of pelvic sentinel lymph nodes (SLNs) in endometrial cancer (EC). Methods: A prospective study of 102 consecutive women with high risk EC scheduled for robotic surgery was conducted. Following cervical injection of a fluorescent

Signaling via Smad2 and Smad3 is dispensable for adult murine hematopoietic stem cell function in vivo

Transforming growth factor-β (TGFβ) is a member of a large family of polypeptide growth factors. TGFβ signals mainly through the intracellular proteins Smad2 and Smad3, which are highly similar in amino acid sequence identity. A number of studies have shown that these proteins, dependent on context, have distinct roles in the TGFβ signaling pathway. TGFβ is one of the most potent inhibitors of hem

Allergic contact dermatitis caused by dimethylthiocarbamylbenzothiazole sulfide (DMTBS) in canvas shoes : In search of the culprit allergen

Background: During rubber vulcanization, new compounds can be formed. Objectives: To report a case of allergic shoe dermatitis in which the search for the allergen ultimately led to the identification of dimethylthiocarbamylbenzothiazole sulfide (DMTBS). Methods: A female presented with eczema on her feet after wearing Sperry Top Sider® canvas sneakers. Patch testing was performed with the Europea

A 0-Hour/1-Hour Protocol for Safe, Early Discharge of Chest Pain Patients

Objectives: Guidelines recommend a 0-hour/1-hour high-sensitivity cardiac troponin T (hs-cTnT) diagnostic strategy in acute chest pain patients. There are, however, little data on the performance of this strategy when combined with clinical risk stratification. We aimed to evaluate the diagnostic accuracy of an accelerated diagnostic protocol (ADP) using the 0-hour/1-hour hs-cTnT strategy together

Growth The Missing Ingredient of Immigrant Entrepreneurship

This thesis muses the question; how do we understand firm growth in immigrant owned firms? Two literature streams are proposed to be relevant. Firstly, theimmigrant entrepreneurship field, which is developing and becoming increasinglysophisticated. Though despite appeals from within the field, that we need a widerspan of concepts to explain the changing heterogeneity and fabric of immigrantentrepr

Multiple scattering by a collection of randomly located obstacles Part III: Theory - slab geometry

In this paper, scattering of electromagnetic waves by discrete, randomly distributed objects inside a (finite thickness or semi-infinite) slab is addressed.In general, the non-intersecting scattering objects can be of arbitrary form, material and shape with a number density of $n_0$ (number of scatterers per volume).The main aim of this paper is to calculate the coherent reflection and transmissio

Identification of opposites and intermediates by eye and by hand

In this eye-tracking and drawing study, we investigate the perceptual grounding of different types of spatial dimensions such as DENSE–SPARSE and TOP–BOTTOM, focusing both on the participants’ experiences of the opposite regions, e.g., O1: DENSE; O2: SPARSE, and the region that is experienced as intermediate, e.g., INT: NEITHER DENSE NOR SPARSE. Six spatial dimensions expected to have three differ

Conjuring up new technology – using magic objects in co-ideation with stroke survivors

Ideation means to generate ideas, and when involving non-designers in these activities they need to be informed about the scope of the possibilities without limiting their imagination. This is a general challenge, which becomes particularly important when it comes to advanced technology ideation together with participants that may not have in-depth knowledge of technological designs and solutions.

Invandring och företagande : Kunskapsöversikt
