This study investigated how untutored learners encode interrogativity intonationaly in a second language. Questions produced in free conversation were selected from longitudinal data of four untutored Italian learners of English. The questions were mostly wh-questions (WQs) and declarative questions (DQs). We examined the use of three crosslinguistically attested question cues: final rise, high...

Abstract. We consider a quantum mechanical system consisting of a linear chain of harmonic oscillators coupled by a nearest neighbor interaction. The system configuration can be closed (periodic boundary conditions) or open (non-periodic case). We show that such systems can be considered as Wigner Quantum Systems (WQS), thus yielding extra solutions apart from the canonical solution. In particu...

Environmental flow requirements, to maintain the functioning of freshwater-dependent ecosystems and restore rivers in ecologically acceptable conditions, depend upon the present water quality status of the river. Various stretches of Vishwamitri River vary in quality and quantity. Water quality index is a tool to converse information regarding water quality of various stretches of river and can...

BACKGROUND Recently, Nigeria emerged as the largest economy in Africa and the 26th in the world. However, a pertinent question is how this new economic status has impacted on the wealth and health of her citizens. There is a dearth of empirical study on the wealth distribution in Nigeria which could be important in explaining the general disparities in their health seeking behavior. An adequate...

River fluoride contamination is one of public health problems. This study aims to determine the water quality status and analyses Cirarab River, Banten-Indonesia. Water sampling was conducted along from up downstream at eight (8) stations February June 2016. analyzed using SPADNS method STORET for determining status. Results show that average ranges 2-2.24 mg/L. The maximum concentration obtain...

in recent years, the water quality of karun river, iran, has been affected by different pollutant loads such as agricultural drainages, municipal and industrial wastewaters.water quality index (wqi) and gis as an efficient tool can be used to provide necessary support for decisions of the management actions in this river and also capability of time series models can be beneficial for forecastin...

The Danube is an international river passing partly through Serbia. The protection of the environment and sustainable use of water resources is a primary task that implies constant monitoring of the quality status and evaluation of ecochemical status of the water in the Danube basin. The investigation includes calculation of all-inclusive water quality by the Serbian water quality index (SWQI) ...

Abstract Selulu Reservoir is located in Waru District, North Panajam Paser Regency. It one of the tourist destinations supporting tourism sector. Land use changes and urbanization have potential impacts on environment. This study aimed to determine Water Quality Status Index (WQI) Reservoir. Hopefully, result will become basis for future reservoir management keep water quality well. The method ...

In evaluation of cancer risk related to environmental chemical exposures, the effect of many chemicals on disease is ultimately of interest. However, because of potentially strong correlations among chemicals that occur together, traditional regression methods suffer from collinearity effects, including regression coefficient sign reversal and variance inflation. In addition, penalized regressi...
