The synthesis, crystal structure, and Hirshfeld surface analysis of N-(4-methoxyphenyl)picolinamide (MPPA), C13H12N2O2, are presented. MPPA crystallizes in the monoclinic space group P21/n, with a single molecule in the asymmetric unit. Structural analysis reveals that all non-hydrogen atoms are nearly coplanar, and the molecule exhibits two intramolecular hydrogen bonds that stabilize its conformation. Supramolecular features include significant intermolecular interactions, primarily C—H...π and various hydrogen bonds, contributing to the overall crystal cohesion, as confirmed by energy framework calculations yielding a total interaction energy of −138.3 kJ mol−1. Hirshfeld surface analysis indicates that H...H interactions dominate, followed by C...H and O...H interactions, highlighting the role of van der Waals forces and hydrogen bonding in crystal packing.

Looking at the heart of things clearly a principle of the Old Testament as well as the New. But in the NT, we learn also that God has concern for the material world and for the details of life, for in the Incarnation He took on all that it is to be human. We read our passages for Divine Liturgy in the light of other Old and New Testament readings that help us to see things in perspective. (Galatians 6:11-18; Luke 12:16-21; 1 Chronicles 28:9)

'What's going on?' Within the context of our critically-informed teaching practice, we see moments of deep learning and reflexivity in classroom discussions and assessments. Yet, these moments of criticality are interspersed with surface learning and reflection. We draw on dichotomous, linear developmental, and messy explanations of learning processes to empirically explore the learning journeys of 20 international Chinese and 42 domestic New Zealand students. We find contradictions within our own data, and between our findings and the extant literature. We conclude that expressions of surface learning and reflection are considerably more complex than they first appear. Moreover, developing critical reflexivity is a far more subtle, messy, and emotional experience than previously understood. We present the theoretical and pedagogical significance of these findings when we consider the implications for the learning process and the practice of management education.

The report further showed that the additional SHO had been previously found guilty of framing a man in a fake case

Temperature is a main driver for most ecological processes, and temperature time series provide key environmental indicators for various applications and research fields. High spatial and temporal resolutions are crucial for detailed analyses in various fields of research. A disadvantage of temperature data obtained by satellites is the occurrence of gaps that must be reconstructed. Here, we present a new method to reconstruct high-resolution land surface temperature (LST) time series at the continental scale gaining 250-m spatial resolution and four daily values per pixel. Our method constitutes a unique new combination of weighted temporal averaging with statistical modeling and spatial interpolation. This newly developed reconstruction method has been applied to greater Europe, resulting in complete daily coverage for eleven years. To our knowledge, this new reconstructed LST time series exceeds the level of detail of comparable reconstructed LST datasets by several orders of magnitude. Studies on emerging diseases, parasite risk assessment and temperature anomalies can now be performed on the continental scale, maintaining high spatial and temporal detail. We illustrate a series of applications in this paper. Our dataset is available online for download as time aggregated derivatives for direct usage in GIS-based applications (Reconstructed MODIS Land Surface Temperature Dataset - http://gis.cri.fmach.it/eurolst/).

In recent times, there has been a greater focus on hygiene in the workplace, likely spurred on by the COVID pandemic. While some germs are completely harmless, others can cause unpleasant illnesses. The chances of a germ surviving largely depends on the type of species, the surface where it is present, and other factors such as ambient temperature or solar radiation.

1,2-Bis(3,5-di­methyl-2-thienyl)perfluoro­cyclo­pentene formed its own spherulites by sublimation onto the hydro­philic surfaces of the (0001) planes of α-quartz and sapphire substrates. The formation of different morphologies of these spherulites was attributed to the surface properties of each substrate. Depending on the morphology of the spherulites, hollow rod crystals with cross sections of different sizes and shapes and branching structures were generated on the surfaces of the spherulites.

Sublimation methods utilizing the surface properties of substrates can address the challenge of controlling hollow morphologies in rod crystals. Spherulites were formed on the hydrophilic surface of the (0001) planes of α-quartz and sapphire substrates by sublimation of 1,2-bis(3,5-dimethyl-2-thienyl)perfluorocyclopentene (1a). Various types of hollow morphologies, distinguished by the size and shape of their cross sections and by the presence or absence of branching structures, were formed separately on α-quartz and sapphire substrates. Such precise control of the hollow morphologies was attributed to the wettability of each substrate, leading to the formation of spherulites of 1a. In addition, it was indicated that the formation process of the surface morphologies of spherulites was associated with the hollow morphologies of rod crystals of 1a.
