In nitrogen (N)-limited systems, the potential to sequester carbon depends on the balance between N inputs and losses as well as on how efficiently N is used, yet little is known about responses of these processes to changes in plant species richness, atmospheric CO2 concentration ([CO2]), and N deposition. We examined how plant species richness (1 or 16 species), elevated [CO2] (ambient or 560...

Spaţiile virtuale 3D devin din ce în ce mai mult utilizate, de la jocuri până la aplicaţii industriale, medicale, militare sau ştiinţifice. Unele dintre cele mai importante aplicaţii ale acestora sunt în e-learning şi edutainment. Lucrarea de faţă prezintă elementele constitutive şi aspecte ale creării unui”muzeu virtual 3D”, pornind de la experienţa autorilor în dezvoltarea aplicaţiei software...

Tattoos have been practiced for thousands of years and remains a common practice in various cultures and countries. Tattooing has gained popularity in Western society where about 10% of the population has at least one decorative tattoo. Lately the same phenomenon can be also observed in Romania. Metal salts or organic compounds are the pigments used in tattooing to achieve a different color. Th...

The counterpart theorist has a problem: there is no obvious way to understand talk about actuality in terms of counterparts. Fara and Williamson have charged that this obstacle cannot be overcome. Here I defend the counterpart theorist by offering systematic interpretations of a quantified modal language that includes an actuality operator. Centrally, I disentangle the counterpart relation from...

It is widely believed that for all p, or at least for all entertainable p, it is knowable a priori that (p iff actually p). It is even more widely believed that for all such p, it is knowable that (p iff actually p). There is a simple argument against these claims from five antecedently plausible premises. The argument is given below. Here ‘A’, ‘E’, ‘K’, ‘ ’, ‘^’ stand for ‘Actually’ ‘Someone e...

Rezumat: Sănătatea fizică și psihică bună reprezintă indubitabil unele dintre cele mai prețioase calități pe care le poate poseda o persoană. Fără aceste elemente, orice activitate simplă devine un efort iar orice efort devine o imposibilitate. Astfel, o mare parte din populația din România care se prezintă în camera cu gardă cu stare generală alterată dată de hipertensiunea arteriala (HA) rapo...

Writing can be defined in a variety of ways. In this examination of learning to write, we view writing as a complex cognitive process and examine instruction that is designed to enable writers to communicate their ideas effectively and perform well in academic settings, on standardized assessments such as the Nation’s Report Card (Salahu-Din, Persky, & Miller, 2008), and in the modern workplace...

In this study biogeochemical export in a set of catchments that vary from 6ha to almost 1500ha is investigated. Studying catchments across this large range of scales enables us to investigate the scale dependence and fundamental processes controlling catchment biogeochemical export that would not have been possible with a more limited data set. The Devil Canyon catchment, in the San Bernardino ...
