We find no evidence for the presence of genuinely young galaxies in our Local universe. We argue that the metal deficiencies and the behavior of the N/O and C/O ratios meet several plausible explanations involving the primary and secondary nature of these elements and their dispersion and mixing by massive stars and intermediate mass stars. Colors are to be analysed using surface photometry and...
متن کاملAre there any natural resources?
Local and regional environments have for many centuries been seen as, or as being composed of, ''natural resources,'' which have generally been considered fully available for human use, irrespective of any use to which other species, purposefully or not, might put them. The global environment has more recently, though less routinely, been seen in this way. I examine full-human-use arguments in ...
متن کاملAre There Any Differences in Seismic Performance Evaluation Criteria for Concrete Arch Dams?
Differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. A numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. Reservoir is modeled using the Eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. Dynamic equilibr...

متن کاملParaneoplastic Scleroderma: Are There Any Clues?
Dear Editor, Scleroderma associated with neoplasia is rare, with only a small number of cases reported. We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adeno...
