The idea of a common language has always existed in some form in China, from the ya yan of Confucius to the modern day mandarin – known as Putonghua. During the Qing dynasty the Beijing dialect slowly became dominant, and in the years following the Xinhai revolution this was made formal through a series of decisions aimed at standardizing the language.

Partially due to years of poor water management practices in Moldova, water resources are increasingly becoming a concern. This situation is intensified by the pollution of water bodies that could be used for drinking water supply. An improvement of the water supply system in Moldova’s capital city Chisinau would result in an upgrading of water quality and hence increased health and living conditi

Fjärranalys har med hjälp av bilder med hög temporär upplösning blivit ett kraftigt verktyg för att övervaka Land use/Land cover (LULC) förändringar. Sudan har under lång tid varit utsatt för intensiv Markanvändning/Markytsförändringar (LULC). Dessa LULC förändringar har resulterat i omfattande land degradering. Omvandlingen av naturskog och skog är fortfarande den vanligaste orsaken till expansioRemote sensing with high temporal resolution images has become a very strong tool for monitoring the Land use/Land cover (LULC) changes. Sudan has long been experiencing intense LULC changes. These LULC changes have resulted in widespread land degradation. The conversion of natural woodland and forest is still the main source for agricultural expansion in Sudan. Rainfed mechanized farming (RMF) is

The Gaia satellite, to be launched in August 2012, will measure highly accurate absolute parallaxes of hundreds of millions of stars. This is done by comparing parallactic displacement of stars in different parts of the sky. The accuracy of this method highly depends on the stability of the so-called basic angle between the two fields of view of the Gaia instrument, and periodic variations could l

Ett antal studier har visat att buller har negativa hälsoeffekter (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Exempel på problem som kan uppstå på grund av buller är sömnsvårigheter, hjärt- och kärlsjukdomar, minskad inlärning och reducerad kognitiv förmåga (Berglund, Lindvall & Schwela 1999). Dessa typer av hälsoproblem leder till lidande för den enskNoise has negative health effects according to a number of studies (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Example of problems that can occur from exposure to noise is sleeping disturbances, heart diseases, lessened learning and reduced cognitive performance (Berglund, Lindvall & Schwela 1999). This kind of problems cause suffering on a personal le
