Programming as a semiotic system to support physics students' construction of meaning: A pilot study

The paper describes a pilot study where programming was introduced to a small group of Swedish upper secondary students with the intent to showcase how programming could be used to construct meaning about different physics concepts. The study found that the students realized the potential of programming as a tool to investigate and explore physics. The results were then described using the theoret

Can grating interferometry-based mammography discriminate benign from malignant microcalcifications in fresh biopsy samples?

PurposeIn addition to absorption imaging, grating interferometry-based mammography (GIM) is capable of detecting differential-phase and scattering signals. In particular, the scattering signal can enable a quantifiable characterization of breast lesions. The purpose of this study was to determine if suspicious microcalcifications associated with benign or malignant lesions can be discriminated bas

Influence of cBN content, Al2O3 and Si3N4 additives and their morphology on microstructure, properties, and wear of PCBN with NbN binder

Polycrystalline cubic boron nitride (PCBN) tool materials with NbN binder without additives and PCBN with Al2O3 or Si3N4 micropowder and whisker additives were manufactured and compared. PCBN materials with Si3N4 whisker reinforcement have the best mechanical properties of all the evaluated materials. Composites reinforced with Al2O3 whiskers have the lowest fracture toughness. However, Al2O3 whis

Dietary Intake across Reproductive Life Stages of Women in India: A Cross-Sectional Survey from 4 Districts of India

Nutritional deficiencies among women of reproductive age, especially from socially backward classes, are widely prevalent in India. The present study aimed to assess the nutrient intakes and analyse their associations with sociodemographic attributes among socially backward adolescent girls, newly married women, pregnant women, and lactating mothers from four districts of India. Further, the study

Cysteinyl leukotriene receptor 1 promotes 5-fluorouracil resistance and resistance-derived stemness in colon cancer cells

Colon cancer is a therapy-resistant cancer with a low 5-year survival frequency. The drug 5-fluorouracil (5-FU) has been used as a first-line therapy in metastatic colon cancer in combination with leucovorin or oxaliplatin with a >40% resistance rate. High CysLT1R expression in tumors is associated with poor survival of colon cancer patients. We sought to examine the role of CysLT1R in 5-FU resist

Hydrophobic cryogels prepared via cryo-polymerization as oil carriers for biosynthesis of sophorolipids

Microbial synthesis of high-value biochemicals like biosurfactants using renewable substrates has attracted an intensive interest in the past decade. In this work, the bioproduction of sophorolipids was achieved by fermentation of different vegetable oils with the strain of Candida bombicola A0803 using novel hydrophobic poly(butyl methacrylate)(pBMA) cryogels as the oil substrate delivery carrier

Strain partitioning and back-stress evaluation in harmonic-structure materials

Heterogenous bimodal harmonic-structure (HS) materials are interesting because of excellent structural efficiency. In this work, we present a simple yet powerful analytical model allowing to evaluate strain partitioning between coarse- and ultrafine- grain (CG and UFG, respectively) structure components in HS materials and to estimate the magnitude of back-stress forming at their interphases. The

Protective effect of intermediate doses of hydrogen sulfide against myocardial ischemia-reperfusion injury in obese type 2 diabetic rats

Objective: Subjects with type 2 diabetes (T2D) have lower circulating hydrogen sulfide (H2S) levels following myocardial ischemia and a higher risk of mortality. The aim of this study was to determine the dose-dependent favorable effects of sodium hydrosulfide (NaSH) on myocardial ischemia-reperfusion (IR) injury in rats with T2D. Methods: T2D was induced using a high-fat diet (HFD) and low-dose o

Calcium activates purified human TRPA1 with and without its N-terminal ankyrin repeat domain in the absence of calmodulin

Extracellular influx of calcium or release of calcium from intracellular stores have been shown to activate mammalian TRPA1 as well as to sensitize and desensitize TRPA1 electrophilic activation. Calcium binding sites on both intracellular N- and C-termini have been proposed. Here, we demonstrate based on Förster resonance energy transfer (FRET) and bilayer patch-clamp studies, a direct calmodulin

A soil microbial model to analyze decoupled microbial growth and respiration during soil drying and rewetting

Soils are continuously exposed to cycles of drying and rewetting (D/RW), which drive pronounced fluctuations in soil carbon (C) fluxes. These C dynamics are characterized by a decoupled behavior between microbial biomass synthesis (growth) and CO2 production (respiration). In general, respiration rates peak shortly after RW and subsequently decrease, while the growth peaks lag several hours behind

Morphological and structural heterogeneity of solid gliadin food foams modified with transglutaminase and food grade dispersants.

We show in this study the impact of transglutaminase (SB6), glycerol (Gly) and linoleic acid (LA) on the development of gliadin (Glia) solid edible foams. Two concentrations of SB6 were tested, 0.58 U/g and 1.17 U/g, and sufficiently high concentration of SB6 was found essential to crosslink the gliadins. Greater cross-linking in foam prepared with gliadin and 1.17 U/g of SB6 (2-TG-Glia) was follo

Preventing kidney injury among sugarcane workers : Promising evidence from enhanced workplace interventions

Objectives: To assess if improvement of working conditions related to heat stress was associated with improved kidney health outcomes among sugarcane harvest workers in Chichigalpa, Nicaragua, a region heavily affected by the epidemic of chronic kidney disease of non-traditional origin. Methods: Based on our findings during the 2017-2018 harvest (harvest 1), recommendations that enhanced the rest

Ultrastructural evidence for self-replication of alzheimer-associated Aβ42 amyloid along the sides of fibrils

The nucleation of Alzheimer-associated Aβ peptide monomers can be catalyzed by preexisting Aβ fibrils. This leads to autocatalytic amplification of aggregate mass and underlies self-replication and generation of toxic oligomers associated with several neurodegenerative diseases. However, the nature of the interactions between the monomeric species and the fibrils during this key process, and indee

Longitudinal association between housing accessibility and activities of daily living : The role of self-efficacy and control in people ageing with Parkinson's disease

Background: External housing-related control beliefs (HCB) and general self-efficacy (GSE) influence different health outcomes in the general ageing population, but there is no information of their role in people ageing with Parkinson's disease (PD). This study aimed to longitudinally assess the role of external HCB and GSE on the association between housing accessibility and activities of daily l
