Abstract Both climate change and rapid urbanization accelerate exposure to heat in the city of Kampala, Uganda. From a network low-cost temperature humidity sensors, operational 2018–2019, we derive daily mean, minimum maximum Humidex order quantify explain intra-urban stress variation. This temperature-humidity index is shown be heterogeneously distributed over city, with mean Index deviation ...

The Hepialidae represents an early branch of the Lepidoptera, whose members lack the ultrasonic hearing and other obvious predator defence systems present in other extant moths. I observed lekking male ghost swifts, Hepialus humuli, being exploited by northern bats, Eptesicus nilssonii, over a hayfield in southern Sweden. Because the moth's display flight was restricted to a brief (30 min) peri...

Ecological theory differentiates rainforest and open vegetation in many regions as functionally divergent alternative stable states with transitional (ecotonal) vegetation between the two forming transient unstable states. This transitional vegetation is of considerable significance, not only as a test case for theories of vegetation dynamics, but also because this type of vegetation is of majo...

− The comparison of three different algorithms for the estimation of parameters of two sine signals with common frequency is presented. The algorithms are the ellipse fit, the seven parameter sine fit and the spectral sinc fit. The comparison includes signal to noise ratio analysis, amplitude analysis and phase difference analysis.

Multiculturalism and its associated plurality of value systems is rapidly becoming the norm in modern medical practice. Given this increasing diversity, greater emphasis upon cultural and ethical competence in physician training is necessary in order to provide culturally sensitive and ethically sound care. Religious values shape ethical codes and are expressed in the cultural norms of subcommu...

The estimate of the damage caused by the earthquake and other natural disasters in the first days after the occurrence of these events can provide a quick damages assessment and help to manage the crisis. Several methods are available to investigate the extent of earthquake’s damage. Optical remote sensing, photogrammetric methods (UAVs and LIDARs), radar interferometry (InSAR) and field observ...

Classic island biogeography theory predicts that very small islands, near the extreme lower end of the species area relationship, should support very few species. At times no species may be present, however, due to randomness in the immigration extinction dynamics. Alternatively, a lack of vegetation on very small islands may indicate that such islands do not contain the appropriate habitat for...

One of the influential tools concerning the rangeland and vegetation sciences isthe technology of remote sensing and satellite data. Satellite data have played essentialroles in preparing the needed information for studying the vegetation. Vegetation has beenwidely recognized as one of the best indicators for determining the land conditions. Usingvegetation indices is one of the techniques of r...
