Understanding the factors controlling spatial and temporal variability of atmospheric methane concentration (XCH4) is crucial for mitigating its impacts and implementing emission reduction strategies. This study comprehensively investigates XCH4 and its driving factors (environmental, meteorological, and anthropogenic activity) across Iran over 20 years, from 2003 to 2022. It combines multi-source
Context. The HD 15337 (TIC 120896927, TOI-402) system was observed by the Transiting Exoplanet Survey Satellite (TESS), revealing the presence of two short-period planets situated on opposite sides of the radius gap. This offers an excellent opportunity to study theories of formation and evolution, as well as to investigate internal composition and atmospheric evaporation. Aims. We aim to constrai
Cross-border multi-modal and railway transportation often faces different risks and problems creating delays, sometimes driven by technical or administrative discontents between countries. For cold supply chains, the risks of such delays get even more important to understand and handle, due to the perishable characteristics of the goods. While some previous research has dealt with risk assessment
This book challenges earlier understandings of early modern dissertations as unimaginative academic exercises. It argues for their continuous importance in scholarly and scientific discourse, and describes the richness and diversity of their subjects and themes. The book contains a complete catalogue of the almost 20,000 Swedish dissertations defended in Uppsala, Lund and Åbo, 1600 to 1820. The ca
The existence or absence of motivation among project members can determine whether or not a project succeeds or fails. Establishing and maintaining motivation, however, are difficult tasks for project managers. Individuals have different triggers of motivation and it is a complex task to understand the underlying motivational drivers of every member of a project, especially because projects are ch
This thesis deals with how computationally effective lattice models could be used for inference of data with a continuous spatial index. The fundamental idea is to approximate a Gaussian field with a Gaussian Markov random field (GMRF) on a lattice. Using a bilinear interpolation at non-lattice locations we get a reasonable model also at non-lattice locations. We can thus exploit the computational
Quantitative in-cylinder measurements of soot volume fraction in a single-cylinder HSDI Diesel engine, based on a VOLVO D5, has been carried out using the laser-induced incandescence (LII) technique using laser excitation at 1064 nm and an ICCD camera with prompt gate detection. Quantitative data was obtained by relating the LII signal response from the engine to that from a calibration flame. The
Study region: The NekooAbad Irrigation District in central Iran faces challenges due to inefficient surface water distribution. 82 million m3 of groundwater is extracted annually from 15,000 tube-wells, leading to decreased groundwater levels and increased energy consumption of 234 million kWh per year. Study focus: This study explores implementing automation in surface water distribution to reduc
Atmospheric Carbon Dioxide (CO2), a significant greenhouse gas, drives climate change, influencing temperature, rainfall, and the hydrologic cycle. This alters precipitation patterns, intensifies storms, and changes drought frequency and timing of floods, impacting ecosystems, agri-culture, water resources, and societies globally. Understanding how global CO2 fluctuations impact regional atmospher
In this paper, I examine ideas on creation, nature, and the ethical self as conceptual-ized by the Ikhwān al-Ṣafāʾ (Brethren of Purity, fl. ca. 350–369/961–980) and al-Rāghibal-Iṣfahānī (d. before 409/1018), with a particular focus on Abū Ḥāmid al-Ghazālī(d. 505/1111). Drawing from the classical scholarship on kalā m, taṣawwuf, and falsafa,I analyze texts by these ethicists who wrote on nature an
Weather radars detect more than weather, they also continuously register the movements of billions of animals aloft in the lower atmosphere. This makes archived, unfiltered weather radar data a goldmine for biological monitoring purposes, providing coverage of the aerial habitat in a way no other method can. Here we present two datasets of biological data extracted from European weather radar data
More complex understanding of relationality in care networks around patients with life-limiting illness and their significant others is needed. This is the case not only because care is distributed unequally along gendered lines, but also because of the changing landscape of care in welfare states where families and communities are made more self-responsible. This study examines everyday experienc
