One of the largest karst springs in North China, the Jinci Springs, dried up and has remained dry since 1994. We develop a correlation analysis with time-lag and a regression analysis with time-lag to study the relation between spring flow and precipitation. This allows us to obtain a better understanding of karst hydrological processes by differentiating the contribution of variation in precip...

Archaea can respond to changes in the environment by altering the composition of their membrane lipids, for example, by modification of the abundance and composition of glycerol dialkyl glycerol tetraethers (GDGTs). Here, we investigated the abundance and proportions of polar GDGTs (P-GDGTs) and core GDGTs (C-GDGTs) sampled in different seasons from Tengchong hot springs (Yunnan, China), which ...

Both notional and grammatical number affect agreement during language production. To explore their workings, we investigated how semantic integration, a type of conceptual relatedness, produces variations in agreement (Solomon & Pearlmutter, 2004). These agreement variations are open to competing notional and lexical-grammatical number accounts. The notional hypothesis is that changes in number...

Understanding the dynamics of dissent and heresy in medicine can be aided by the use of suitable frameworks. The dynamics of the search for truth vary considerably depending on whether the search is competitive or cooperative and on whether truth is assumed to be unitary or plural. Insights about dissent and heresy in medicine can be gained by making comparisons to politics and religion. To exp...

In this chapter, we investigate the variation in form, syntax and semantics of the plural words found across the Alor-Pantar languages. We study five AP languages: Western Pantar, Teiwa, Abui, Kamang and Wersing. We show that plural words in Alor-Pantar family are diachronically instable: although proto-Alor-Pantar had a plural number word *non, many AP languages have innovated new plural words...

The challenges that sub-Saharan Africa has faced in the post-colonial period have come to characterise the way the region is perceived. These narratives are especially evident in the various ways children's lives are discussed, leading to a particular focus on childhoods in difficult circumstances or at the margins. This has eclipsed the mundanities of everyday life for many children whose live...

to evaluate the hydrogeochemical characteristics of karst water resources of oshtorankooh, chemistry details of springs has been considered as the most important evacuator of karst resources. this research has been performed to study hydrogeochemical nature of karst springs and their origin with an emphasis on the type of formation.  accordingly, five samples of the water of permanent springs o...

Evaporation of silica-rich geothermal waters is one of the main abiotic drivers of the formation of silica sinters around hot springs. An important role in sinter structural development is also played by the indigenous microbial communities, which are fossilized and eventually encased in the silica matrix. The combination of these two factors results in a wide variety of sinter structures and f...

We present an approach for the localization of passive receiver nodes in a communication network. The only source of information is the time when environmental sound or ultrasound signals are received. The discrete signals occur at unknown positions and times, but they can be distinguished. The clocks of the receivers are synchronized, so the time differences of arrival (TDOA) of the signals ca...
