Relatively high deposition of nitrogen (N) in the northeastern United States has caused concern because sites could become N saturated. In the past, mass-balance studies have been used to monitor the N status of sites and to investigate the impact of increased N deposition. Typically, these efforts have focused on dissolved inorganic forms of N (DIN = NH4-N + NO3-N) and have largely ignored dis...

Sistemele de monitorizare pe scară largă permit colectarea eficientă a datelor din câmp la rezoluții temporale și spațiale ridicate. Un exemplu relevant îl constituie aplicarea acestor sisteme în domeniul monitorizării infrastructurilor de transport al produselor petroliere pentru prevenirea scurgerilor și a accesului neautorizat, ce pot cauza daune de mediu și economice semnificative. Lucrarea...

Many animals, including humans, rely on active tactile sensing to explore the environment and negotiate obstacles, especially in the dark. Here, we model a descending neural pathway that mediates short-latency proprioceptive information from a tactile sensor on the head to thoracic neural networks. We studied the nocturnal stick insect Carausius morosus, a model organism for the study of adapti...

Predators and competitors of vertebrates can in theory reduce the density of infected nymphs (DIN)-an often-used measure of tick-borne disease risk-by lowering the density of reservoir-competent hosts and/or the tick burden on reservoir-competent hosts. We investigated this possible indirect effect of predators by comparing data from 20 forest plots across the Netherlands that varied in predato...

The objectives of this article are to study the sum IS(d) and to find some upper din bounds for Smarandache's function. This sum is proved to satisfy the inequality IS(d) ~ n at most all the composite numbers, Using this inequality, some new din upper bounds for Smarandache's function are found. These bounds improve the well-known inequality Sen) ~ n.

Toplumun temel kurumlarından bir tanesi de dindir. Din, insanlık tarihi ile başlamış ve yaşıt evrensel olgudur. Tarihin her döneminde toplumda var olmuş, günümüzde varlığını en canlı şekilde hissettiren önemli hassas kurumdur. Antropoloji bilimi tarih boyunca bireysel olarak inanmayan kişiler olmakla beraber top yekûn dinsiz topluma rastlanmadığını haber vermektedir. İnsanların huzur mutluluğun...
