Assessing the potential of energy sharing through a shallow geothermal heating and cooling network

Shallow geothermal offers great potential to supply emission-free heating and cooling and has therefore a pivotal role in the transition of heating and cooling networks. This paper presents a novel heating and cooling network with possible geothermal energy sharing between decentralized borefields located at each building level. The system consolidates the benefits of both standalone and centraliz

Image post-processing for SILMAS : structured illumination light sheet microscopy with axial sweeping

In this article, we propose a post-processing scheme for the novel volumetric microscopy technique SILMAS. We demonstrate this scheme on data from an alpha-synuclein transgenic mouse brain. By combining structured illumination and axial sweeping, a SILMAS measurement provides a prerequisite for quantitative data extraction through improved contrast and optical sectioning. However, due to the techn

Evaluation of piezoelectric speaker drivers for loudspeaker and array speaker design

Abstract This thesis is an evaluation of piezoelectric speaker drivers for loudspeaker design. It goes through the electrical and sound generating properties of the speaker drivers and general theory of piezoelectric speaker drivers. A prototype single speaker driver loudspeaker has been realized and evaluated by measuring the frequency response and sound pressure level (SPL), total harmonic disto

Automatic Search Algorithm using Signal Enhancement, Flex Sensors and exploration of Machine learning Features to improve Multiple Channel Neuromuscular Electrical Stimulation (NMES) systems

Neuromuscular Electrical Stimulation (NMES) is a method to stimulate the body's muscles using bursts of electricity on the skin that can strengthen the muscles, increase coordination, and simulate human muscle movement to prevent the formation of Deep Vein Thrombosis (DTV). Electrically sensitive skin areas, called Motor Points (MP), must be stimulated to achieve a robust muscular response and

To block or not : why the British ruling elite enabled the Industrial Revolution during the 18th century

This study explores why the ruling elite in 18th-century Britain not only allowed but actively supported industrialization. Economic rents, political power, and international competition are commonly cited as the reasons, but these explanations lack empirical evidence. By conducting a text analysis of parliamentary legislation and debates on the cotton industry, this study demonstrates that the ru

Jingle-Jangle Fallacies in L2 Motivational Self System Research : A Response to Al-Hoorie et al. (2024)

In a systematic examination of scales commonly used in L2 Motivational Self System (L2MSS) research, Al-Hoorie et al. (2024) found discriminant validity problems. Raising jangle fallacy concerns, they argue that substantive research should be paused until validity issues are ironed out. However, validity at the measurement level is dependent on validity at the construct level. Replication attempts

Consequences of partially recessive deleterious genetic variation for the evolution of inversions suppressing recombination between sex chromosomes

The evolution of suppressed recombination between sex chromosomes is widely hypothesized to be driven by sexually antagonistic selection (SA), where tighter linkage between the sex-determining gene(s) and nearby SA loci is favored when it couples male-beneficial alleles to the proto-Y chromosome, and female-beneficial alleles to the proto-X. Although difficult to test empirically, the SA selection

Testing Quantitative and Qualitative Sex Effects in a National Swedish Twin-Sibling Study of Posttraumatic Stress Disorder

OBJECTIVE: Twin studies have demonstrated that posttraumatic stress disorder (PTSD) is moderately heritable, and the pattern of findings across studies suggests higher heritability in females compared with males. Formal testing of sex differences has yet to be done in twin studies of PTSD. The authors sought to estimate the genetic and environmental contributions to PTSD, and to formally test for

Sex-and age-related variations in myocardial tissue composition of the healthy heart : a native T1 mapping cohort study

Aims: Cardiovascular diseases manifest differently in males and females, potentially influenced by inherent sex- and age-related differences in myocardial tissue composition. Such inherent differences are not well-established in the literature. With this study using cardiac magnetic resonance (CMR) native T1 mapping, we aim to determine the effect of sex and age on myocardial tissue composition in

Secondary Ice Production - current state of the science and recommendations for the future

Measured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>−10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has long been proposed that a secondary ice production process must exist that is able to rapidly enhance the number concentration of the ice population following initial primary ice

Biofilm-dispersed pneumococci induce elevated leukocyte and platelet activation

INTRODUCTION: Streptococcus pneumoniae (the pneumococcus) effectively colonizes the human nasopharynx, but can migrate to other host sites, causing infections such as pneumonia and sepsis. Previous studies indicate that pneumococci grown as biofilms have phenotypes of bacteria associated with colonization whereas bacteria released from biofilms in response to changes in the local environment (i.e.

PET-CT imaging of neuroendocrine tumours - Beyond diagnostics

Background: Neuroendocrine tumours (NETs) typically overexpress somatostatin receptors. By radiolabelling somatostatin analogues with a positron-emitting radionuclide (68Ga-DOTATOC or 68Ga-DOTATATE), these tumours can be detected with high sensitivity and specificity using somatostatin receptor positron emission tomography-computed tomography (PET-CT).Aim: To enhance knowledge about NETs imaged wi

Effects of a Paleolithic diet compared to a diabetes diet on leptin binding inhibition in secondary analysis of a randomised cross-over study

BACKGROUND: Beneficial effects from practising a Paleolithic diet as compared to a diabetes diet on weight, waist circumference, satiety, leptin, HbA1c and glucose control in randomised controlled trial participants with type 2 diabetes could be due to lower leptin resistance. Support for this hypothesis comes from an in vitro experiment that showed that digested wheat gluten, which is excluded fr

Elevated carbohydrate antigen 125 (CA125) is associated with incident heart failure and mortality in acute coronary syndrome

AIMS: Carbohydrate antigen 125 (CA125), a mucin produced by serosal cells in response to mechanical and inflammatory stimuli, has emerged as an important biomarker to guide risk stratification in heart failure (HF). The prognostic value of CA125 in acute coronary syndrome (ACS) patients is less explored.METHODS: In a cohort of 524 ACS patients (73% males, mean age 67 ± 12 years), we assessed the a

An Exhibition History of Latin American Art

An Exhibition History of Latin American Art compiles texts by twenty-one Latin American curators who were asked to select an exhibition that took place in Latin America or focused on the work of Latin American artists and justify its importance, relevance, and influence. The history of Latin American art exhibitions that is thus constructed considers the array of social and institutional contexts

Role of the polyamine transporter PotABCD during biofilm formation by Streptococcus pneumoniae

Streptococcus pneumoniae is a bacterium of great global importance, responsible for more than one million deaths per year. This bacterium is commonly acquired in the first years of life and colonizes the upper respiratory tract asymptomatically by forming biofilms that persist for extended times in the nasopharynx. However, under conditions that alter the bacterial environment, such as viral infec

HAMLET, a human milk protein-lipid complex, modulates amoxicillin induced changes in an ex vivo biofilm model of the oral microbiome.

Challenges from infections caused by biofilms and antimicrobial resistance highlight the need for novel antimicrobials that work in conjunction with antibiotics and minimize resistance risk. In this study we investigated the composite effect of HAMLET (human alpha-lactalbumin made lethal to tumor cells), a human milk protein-lipid complex and amoxicillin on microbial ecology using an ex vivo oral
