Green hydrogen development: An analysis of the Brazilian innovation system

Brazil has received international attention and investment for renewable energy production, including investments to produce low-carbon hydrogen: green hydrogen. However, green hydrogen requires relatively new technology and inputs are still expensive when compared to fossil fuels. The diffusion of this technology depends on the fulfillment of seven innovation functions. This study therefore seeks

Variations on an ancient theme — the central complex across insects

The central complex (CX) is a highly conserved region of the insect brain, and its ubiquitous occurrence suggests that its neural circuits are of fundamental importance. While its overall layout has not changed since the evolution of insect flight, substantial variations exist in the internal organization of all CX components. By changing the details of a system of repeating columns and layers, th

Activating 2D MoS2 by loading 2D Cu–S nanoplatelets for improved visible light photocatalytic hydrogen evolution, drug degradation, and CO2 reduction

Finding reliable photocatalysts capable of driving reactions using only sunlight is more needed than ever. A variety of strategies to harvest sunlight and convert it into chemical energy have been successfully utilized such as synthesizing nanostructures, using metal nanoparticles, doping, and others. In this work, we discover a facile way to anchor CuS nanoplatelets on 2D MoS2 by the solvothermal

Capturing MR personnel's insights is crucial for guiding the development and future applications of noise-reduction technology. This study aimed to explore how MR radiographers manage acoustic noise in clinical MR settings. Methods: Usi

Fundamental Limits on Anomalous Energy Flows in Correlated Quantum Systems

In classical thermodynamics energy always flows from the hotter system to the colder one. However, if these systems are initially correlated, the energy flow can reverse, making the cold system colder and the hot system hotter. This intriguing phenomenon is called "anomalous energy flow"and shows the importance of initial correlations in determining physical properties of thermodynamic systems. He

Searches for New Physics Using Innovative Data Acquisition, Analysis, and Compression Techniques

När forskare blickar ut i universum ser de överallt spåren av en stor mängd osynlig massa. Massan finns där men det går inte att se den. Ungefär 80% av all massa i universum beräknas bestå av denna "mörka materia". Det är som att mänskligheten står på stranden och blickar ut över havet utan att veta vad vatten är. I partikelfysik studeras universums minsta beståndsdelar, elementarpartiklarna, för The high event rate delivered by the Large Hadron Collider (LHC) provides experiments with opportunities for new discoveries as well as challenges related to the large amounts of data recorded. Overcoming this requires innovative techniques in the three topics of this thesis: Data acquisition, data analysis, and data compression.In the data taking period of 2015-2018, the ATLAS experiment received

Orbital hydroclimate variability revealed by grain-size evidence in the tropical Pacific Islands since 140 ka

The past evolution of precipitation and atmospheric convection in the Western Pacific Warm Pool (WPWP) is critical for global climate changes but is under debate because of its forcing mechanisms. Here, we present a high temporal resolution (∼156 years) grain-size record of core MD01–2385 over the last 140 kyr, in offshore northern New Guinea to reveal sediment dynamics as a proxy for precipitatio

Playing with the child within : Early parenthood experiences of parents who were out-of-home placed during childhood

Experience of out-of-home care (OHC) is associated with life-long vulnerability, and research indicates that parents with experiences of OHC are at higher risk of having their own children placed in out-of-home care. However, research on these parents is limited and lacks a resilience perspective. Here, we focused on parents with OHC experience as children but with custody of their own children (N

Esophagus Dilation and Quality of Life in Adults with Scleroderma and Concomitant Obstructive Sleep Apnea

(1) Background: Systemic sclerosis (SSc) is a rare systemic disease, which often affects the esophagus, leading to dilation and complications such as dysphagia and reflux. Obstructive sleep apnea (OSA) is a chronic condition with recurrent episodes of upper airway collapsibility and is known to impair quality of life (QoL). The primary aim of this study was to investigate the occurrence of esophag

Interplay of halogen bonding and solvation in protein-ligand binding

Halogen bonding is increasingly utilized in efforts to achieve high affinity and selectivity of molecules designed to bind proteins, making it paramount to understand the relationship between structure, dynamics, and thermodynamic driving forces. We present a detailed analysis addressing this problem using a series of protein-ligand complexes involving single halogen substitutions - F, Cl, Br, and

Grotta Grande (southern Italy). Disentangling the Neandertal and carnivore interaction in a short-term palimpsest at the last glacial onset (∼116-109 ka)

The Mousterian of the Grotta Grande (Southern Italy) is here subject to new dating, which provide a surprisingly high-resolution on the stratigraphic sequence. Overall, the deposit in the Trench F appears framed in the MIS 5, into a brief chronological time span immediately after the Last Interglacial, between ∼116 ka and 109 ka. Significant archaeological evidence has been found in this sector on

Mortality risk relationship using standard categorized BMI or knee-height based BMI – does the overweight/lower mortality paradox hold true?

Background: The body mass index (BMI) is prone to misclassification of obesity due to age-related height loss and resulting measurement errors. Knee-height based BMI (KH-BMI) has not been previously studied in relation to mortality risk in older adults. Aim: To evaluate the age- and sex-specific mortality risk relationship using classic BMI and knee height predicted BMI (KH-BMI) overweight and obe

Background: Individuals with type 2 diabetes (T2D) are at increased risk of developing cardiovascular disease (CVD) which necessitates monitoring of risk factors and appropriate pharmacotherapy. This study aimed to identify factors predicting emergency department visits, hospitalizations, and mortality among T2D patients after being newly diagnosed with CVD. Methods: In a retrospective observation

Interface-Engineered InAlN/Cu2O Photocathode with Accelerated Charge Separation for Boosting Photoelectrochemical Water Splitting

Cu2O has emerged as a promising material for sustainable hydrogen production through photoelectrochemical (PEC) water splitting, while inefficient charge separation remains one of the main challenges hindering its development. In this work, a new architecture of InAlN/Cu2O heterojunction photocathode is demonstrated by combining n-type InAlN and p-type Cu2O to improve the charge separation efficie

Intensity analysis applied to land use and land cover change and transitions in a fragile tropical mountain environment : a case of sironko catchment on Mt. Elgon, Eastern Uganda

Intensity Analysis (IA) of land use and land cover change (LULCC) is important to support policy and practice. We applied IA to analyse LULCC in Sironko catchment, Uganda. Results show that agricultural land, forest, and wetland reduced by 8%; 32%; and 20% between 1986-2000. Between 2000-2016, forest, wetland, and built-up areas increased by 84%, 5%, and 57%. Active gainers between 1986-2000 were

Fashionable detachments : Wardrobes, bodies and the desire to let go

Consumers are increasingly asked to “empty out their closets,” to “de-clutter” or in other ways detach themselves from the textile surplus of their wardrobes. In this article, fashion is examined as a process of detachment. Building on ethnographic wardrobe interviews, wardrobe clearances and group discussions with consumers, detachment is viewed as a fundamental, yet underexamined, process of fas

Transport-based fusion that distinguishes between Majorana and Andreev bound states

It has proven difficult to distinguish between topological Majorana bound states and nontopological Andreev bound states and to measure the unique properties of the former. In this work, we aim to alleviate this problem by proposing and theoretically analyzing a different type of fusion protocol based on transport measurements in a Majorana box coupled to normal leads. The protocol is based on swi
