Background: Previous research shows that critical constructive feedback, that scaffolds students to improve on tasks, often remains untapped. The paper’s aim is to illuminate at what stages students provided with such feedback drop out of feedback processing. Methods: In our model, students can drop out at any of five stages of feedback processing: (1) noticing, (2) decoding, (3) making sense, (4)

Multiple-input multiple-output (MIMO) is a key enabler for high data rates in mobile communications. However, it is challenging to design MIMO terminal antennas for LTE bands below 1 GHz, due to the conventional chassis offering only one resonant characteristic mode (CM). Recently, it was shown that minor structural changes can yield up to two additional resonant modes for designing two-port MIMO

[N,N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine] (L1) and [N,N-bis(2-quinolylmethyl)-N-bis(2-pyridyl)methylamine] (L2) were employed to prepare CuII and CuI complexes for spectroscopic and structural characterization. [L1CuII(H2O)](NO3)2 and [L2CuII(NO3)]NO3 have Jahn–Teller distorted octahedral geometries and give rise to isotropic EPR spectra in frozen solution. [L1CuI(CH3

Background: Depressive symptoms are common in rheumatic diseases and influence patients’ quality of life. The Patient Health Questionnaire-9 (PHQ-9), which assesses symptoms of depression, is valid in English in patients with systemic sclerosis (SSc). However, the measurement properties of the PHQ-8 (short version of the PHQ-9) have not been evaluated in Swedish patients with SSc. Objective: To in

Background: A contralateral occult inguinal hernia is frequently observed in patients planned for a unilateral laparoscopic inguinal hernia repair. Surgical strategy for contralateral groin management in patients scheduled for an endo-laparoscopic unilateral inguinal hernia repair is controversial and based on questionable evidence. This study aimed to gather international opinion concerning the s

Crowd models can be used for the simulation of people movement in the built environment. Crowd model outputs have been used for evaluating safety and comfort of pedestrians, inform crowd management and perform forensic investigations. Microscopic crowd models allow the representation of each person and the obtainment of information concerning their location over time and interactions with the phys

Background: Patients with chronic kidney disease (CKD) have poor outcomes following myocardial infarction (MI). We performed an untargeted examination of 175 biomarkers to identify those with the strongest association with CKD and to examine the association of those biomarkers with long-term outcomes. Methods: A total of 175 different biomarkers from MI patients enrolled in the Swedish Web-System

Molecular motors and machines are essential for all cellular processes that together enable life. Built from proteins with a wide range of properties, functionalities and performance characteristics, biological motors perform complex tasks and can transduce chemical energy into mechanical work more efficiently than human-made combustion engines. Sophisticated studies of biological protein motors h

Background: Lipoprotein-associated phospholipase A2 (Lp-PLA2) activity has been shown to predict calcific aortic valve stenosis (CAVS) outcomes. Our objective was to test the association between plasma Lp-PLA2 activity and genetically elevated Lp-PLA2 mass/activity with CAVS in humans. Methods and results: Lp-PLA2 activity was measured in 890 patients undergoing cardiac surgery, including 476 pati

The development and application of geochemical techniques to identify redox conditions in modern and ancient aquatic environments has intensified over recent years. Iron (Fe) speciation has emerged as one of the most widely used procedures to distinguish different redox regimes in both the water column and sediments, and is the main technique used to identify oxic, ferruginous (anoxic, Fe(II) cont

Outer dendritic segments of olfactory receptor neurons tuned to sex pheromone components were measured morphometrically on the antenna of male European corn borers. Ostrinia nubilalis, to determine if a correlation exists between the diameter of the outer dendritic segment and the spike amplitude. The olfactory sensilla investigated each contained three receptor cells. Two cells were each specific

The electrophysiological and behavioral responses of male Agrotis segetum to fluorinated analogs of (Z)-5-decenyl acetate (Z5-10:OAc) were investigated. The single sensillum recordings showed that 4,4-difluoro-(Z)-5-decenyl acetate (4,4-F2), 7,7-difluoro-(Z)-5-decenyl acetate (7,7-F2), 10,10,10-trifluoro-(Z)-5-decenyl acetate (10,10,10-F3) and 7,7,8,8-tetrafluoro-(Z)-5-decenyl acetate (7,7,8,8-F4)

The alkenyl acetates E9-12:Ac, ∆ll-12:Ac and Zll-14:Ac were identified as minor components of the C. murinana female pheromone blend by chemical analyses of volatile pheromone gland constituents and potential pheromone precursors, electrophysiological recordings from single receptor cells, and field trapping tests. Gland washes from virgin females contained these compounds at 3%, 10% and 5%. respe

A wind-borne plume of sex pheromone from a female moth or a synthetic source has a fine, filamentous structure that creates steep and rapid fluctuations in concentration from a male moth flying up the plume's axis. The firing rates from single antennal neurons on Agrotis segetum antennae decreased to nearly zero within seconds after the antennae were placed in a pheromone plume 70 cm downwind of a

The sex pheromones produced by virgin females of three species of small ermine moths occurring sympatrically on the European spindle tree were analysed by gas chromatography and the synthetic compounds tested against male moths in the laboratory and field. Pheromone gland extracts of Yponomeuta cagnagellus were shown to contain tetradecyl acetate, (E)‐11‐ and (Z)‐11‐tetradecenyl acetate, tetradeca

Sex pheromone biosynthesis in the codling moth Cydia pomonella (Lepidoptera; Tortricidae) was studied by topical application of deuterated fatty acids in DMSO to pheromone glands. The incorporation of deuterium label into fatty acids and alcohols in the pheromone gland was monitored by gas chromatography with flame ionization detection and mass spectrometry in the selected ion monitoring mode. Dod

A model for mate competition in moths sexually signalling with pheromones is presented. The model has four variables. N is the number of individuals of each sex per area unit. r is the length of the female odour plume as detected by a responding male. ε is a parameter increasing with male ability to discriminate between concentrations. r-ε becomes the competitive part of the female pheromone plume
