importance of infection control should be highlighted for both clinical and preclinical dental students, to provide safe dental treatment to the patients as well as protection of the dentists and healthcare workers.Vegetation is a key component of salt marsh monitoring programs, but different methods can make comparing datasets difficult. We compared data on vegetation composition and cover collected with 3 methods (point-intercept, Braun-Blanquet visual, and floristic quality assessment [FQA]) in 3 Rhode Island salt marshes. No significant differences in plant community composition were found among the methods, and differences in individual species cover in a marsh never exceeded 6% between methods. All methods were highly repeatable, with no differences in data collected by different people. However, FQA was less effective at identifying temporal changes at the plot scale. If data are collected from many plots in a marsh, any of the methods are appropriate, but if plot-scale patterns are of interest, we recommend point-intercept.The resettlement of herders in pastoral zones is often criticized for hindering pastoral mobility, which is essential to survival. We integrate narratives of conflict and environmental change with maps to demonstrate the complementarity between pastoral mobility - porous borders- and border demarcation - rigid borders. We use evidence from the Sondré-Est Pastoral Zone in southern Burkina Faso, where herders were voluntarily resettled near agricultural villages following the droughts of the 1970s. Over time, however, farmers encroached on the borders of the pastoral zone and surrounding grazing areas declined. This increased land-use disputes. Tensions were exacerbated by the fact that these communities kept maps as community secrets. We re-created the administrative boundaries of the pastoral zone to map land-use/land-cover changes and conflict hot spots. The maps show that conflicts happened along porous borders where agricultural fields encroached. Herders called for a clear demarcation of the border of the pastoral zone to preserve exclusive access to resources within it. Simultaneously, they also wanted to maintain shared access to other resources outside the pastoral zone. The herders' desire for both border clarity and some form of flexibility underlines the complementary between both processes, especially in times of resource scarcity and land-use conflict. The mystery around the maps helps sustain ambiguity that is key for pursuing both goals.A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was constructed from scratch to be used through the Interactive Board (IB) as a learning tool by three different student groups (N = 154). In the first stage of the learning process, all groups used only the digital material of the DA. In the second stage, the three groups used different learning tools of the DA. Through the IB, the first group used Arduino experiments, the second one the VLs, and the third only static visualizations. A pre- to post-test statistical analysis demonstrated that the first two groups were equivalent in regard to achievement in declarative knowledge tests and of a higher level than the third group. Therefore, it can be concluded that conducting Arduino experiments in a mixed virtual-physical environment results in equivalent learning gains in declarative knowledge as those attained by using VL experimentation through the IB.Azulene is an aromatic hydrocarbon that possesses a unique chemical structure and interesting biological properties. Azulene derivatives, including guaiazulene or chamazulene, occur in nature as components of many plants and mushrooms, such as Matricaria chamomilla, Art
