The ca. 3.48 Ga Dresser Formation, Pilbara Craton, Western Australia, is well known for hosting some of Earth's earliest convincing evidence of life (stromatolites, fractionated sulfur/carbon isotopes, microfossils) within a dynamic, low-eruptive volcanic caldera affected by voluminous hydrothermal fluid circulation. However, missing from the caldera model were surface manifestations of the vol...

The purpose of this study is to develop HOT (Higher Order Thinking) Lab–based practicum guide that improves pre-service physics teachers’ creative thinking skills. The research method used 3D-1I model (Define, Design, Develop and Implementation). The subjects of this study are 40 students of Physics Education Program UIN Sunan Gunung Djati Bandung. The results showed that the HOT Lab-based prac...

This review summarizes a decade of research in which we have used molecular methods, in conjunction with more traditional approaches, to study hot spring cyanobacterial mats as models for understanding principles of microbial community ecology. Molecular methods reveal that the composition of these communities is grossly oversimplified by microscopic and cultivation methods. For example, none o...

Hot temperatures lead to heightened arousal. According to excitation transfer theory, arousal can increase both antisocial and prosocial behavior, depending on the context. Although many studies have shown that hot temperatures can increase antisocial behavior, very few studies have investigated the relationship between temperature and prosocial behavior. One important prosocial behavior is vot...

Understanding the link between temperature and educational outcomes is important in assessing the returns to various schooling interventions and the potential welfare impacts of climate change. Using student-level administrative data for the largest public school district in the United States, I estimate the causal impact of hot temperature on high-stakes exams and subsequent educational attain...

The fully three dimensional governing equations in the electron magnetohydrodynamic (EMHD) regime for a plasma with inhomogeneous density is obtained. These equations in the two dimensional ( 2-D) limit can be cast in terms of the evolution of two coupled scalar fields. The nonlinear simulations for the two dimensional case are carried out to understand the propagation of EMHD magnetic structur...

Overheating during hot summers is a major risk which will increase under climate change. Thermal dynamic modelling is used to compare the current overheating risk of typical residential properties in the UK with the future overheating risk for the middle decades of this century, i.e. the period 20402069. A wide range of passive and low-energy climate change adaptation measures which could be re...

OBJECTIVE To assess the prevalence, onset, duration and severity of hot flashes in men after bilateral orchidectomy (BO) for prostate cancer, to evaluate body temperature changes during hot flashes and to determine whether an elevated temperature within a few days after BO can be caused by deprivation of androgen. MATERIALS AND METHODS Patients (n = 101) were questioned about the characterist...

Based on the Stable Ecotype Model, evolution leads to the divergence of ecologically distinct populations (e.g., with different niches and/or behaviors) of ecologically interchangeable membership. In this study, pyrosequencing was used to provide deep sequence coverage of Synechococcus psaA genes and transcripts over a large number of habitat types in the Mushroom Spring microbial mat. Putative...

PURPOSE This manuscript reports the data from two interventions on human subjects aiming to determine the effect of elevated core (HOT-core, study 1, 14 participants) and skin (HOT-skin, study 2, 11 participants) temperature on the force / EMG relationship. METHODS In both studies, participant underwent an experimental trial and a control (CON) trial, in which maximal voluntary contractions (...
