I, and other authors, have discussed in several recent publications that “linear” triatomic molecules (defined as having linear equilibrium structures) are necessarily observed as being bent on ro-vibrational average. We have demonstrated this theoretically by calculations of the rotation–vibration expectation values, [Formula: see text], where [Formula: see text] is the bond angle supplement, [Formula: see text] being the instantaneous value of the bond angle of the triatomic molecule A–B–C. Direct experimental evidence of bent average structures has been obtained by other authors in Coulomb explosion imaging experiments, and indirect evidence from re-interpretation of experimentally derived rotational constant values. In spite of a rather significant amount of evidence in support of the bent average structures, the idea has been heavily criticized. In the present work I discuss in more detail some of the arguments for the bent average structures put forward in previous papers, and I hope to correct and clarify some of the misunderstandings leading to the criticisms. Part of the criticism originates in a widespread, but fallacious, belief among spectroscopists that linear and bent chain molecules have qualitatively different energy-level and spectral intensity patterns. This is not true. One can view the linear-molecule energy level and spectral patterns as limiting cases of the bent-molecule ones.

This study investigated the relationship between guilt appeal and compliance with social distancing measures. We proposed that the relationship is double mediated by empathy and responsibility for the unfortunate people who have suffered from COVID-19. This research is novel to an extent as an experimental method is used in the Asian context. The results exhibited that guilt positively affected compliance with social distancing measures. The respondents were directly or indirectly compliant due to the emotions of empathy and responsibility. The theoretical and practical contributions of this study were presented.

Cooling is the best preservation method than others because the food that has been cooled will remain fresh and will not experience a change in taste, color and aroma, besides all the activities that cause decay will stop so that the cooled food will last longer. (Hartanto, 1984). With the proper cooling engine planning, it can help with spatial adjustments, adjustments to loading, estimation of the power to be used, and budget plans. That is what is commonly called the cooling load calculation. Calculation of cooling load needs to be carried out before planning. This is necessary because the magnitude of the pending load is very influential on the selection of the cooling engine so that the freezing point for preserving food can be accurate. Pendiginan burden is influenced by external and internal factors. With the experimental method, it is obtained the results of the external cooling load as the external cooling load is 11.6 kW, the inner cooling load is 138.8 kW and the performance work coefficient (COP) is 2.

Character Building

This paper is written to determine the methods and benefits of the integration of religious-science education in experimental based to shape the character of students. Integration of religious education with science and technology means the mastery of science and technology combined with the Islamic sciences and Islamic personalities. Through the experimental method, it is expected the emerging good characters (character building) of learners with the characteristics of faith and taqwa, able to motivate themselves, improving selfconfidence, realizing personal gratitude, and bring good morals. Tulisan ini disusun untuk mengetahui metode dan manfaat integrasi pendidikan agama-sains Berbasis eksperimental untuk membentuk karakter mahasiswa.Integrasi pendidikan agama dengan sains dan teknologi berarti adanya penguasaan sains dan teknologi dipadukan dengan ilmu-ilmu Islam dan kepribadian Islam. Melalui metode eksperimental diharapkan muncul karakter-karakter (character building) baik dari peserta didik dengan ciri beriman dan bertakwa, mampu memotivasi diri, menumbuhkan percaya diri, mewujudkan peribadi bersyukur, dan memunculkan akhlak yang baik.
