Water scarcity is one of the main challenges facing Middle Eastern countries. A typical country in this respect is Syria. This paper estimates projections for the available water resources, water balance, and available water per capita (AWPC) in Syria until 2050 in relation to possible future climate changes, national development agendas, water constraints, and water management alternatives. Resul

The sharing of computer programs, movies and music over the Internet marks an all time high in the persistent controversy between intellectual property owners and reproduction technologies as file sharing has gradually become a natural element in the everyday life of today’s younger generations. At present, the magnitude of the expanding gulf between traditional society’s intellectual property rig

An investigation into the design of neural network controlled autonomous agents that navigate in uncertain environments using pre-existing visual landmarks.

This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication.In chapter two, zero-dimensional Quantum Dots (QDs) are incorporated into electro

Abstract in Chinese 從社會投資（social investment）的社會福利的角度來看，花蓮的發展，長期以來，著重在修復（repair）人口外移與老化的困境，而非預防（prevent）這個現象發生的原因。如果花蓮真的要強調永續發展，我覺得創新的思維應該要著重在預防，像是我們如何把人留下來？把好的產業留下來？〈花東地區發展條例〉裡提到人才東移的政策，花蓮縣綜合實施方案應該要更細部的討論這個部份，不是只有簡化成消費原住民文化的觀光產業，再者，如果觀光或是鄉村旅遊是花蓮發展很重要的一環，我們的教育準備好了嗎？ 最後，在其他國家對鄉村發展大多採用低衝擊的開發（Low impact development）的今天，我們能不能勇敢的說，我們不需要靠空中纜車，也可以欣賞到美景，我們不需要賽車場，也可以找到觀光的出路呢？ 花蓮縣政府在九月十六日舉辦了花蓮縣綜合實施方案初稿的聽證會，

A discussion of motivations for doing archaeology. In the present there is a conflict between three different perspectives: Enlightment, teraphy and morale. The three perspectives go back to the Antique philosophical concepts of the truth, the beauty and the good, correlating to epistemology, estetics and ethics.

Practitioners and transport planners should be aware of the different policies in transport planning and laws and regulations in relation to them. Nevertheless, research has shown that implementation of transport policies, whatever their focus may be, does not always result in them being employed in the daily transport planning. In Sweden, accessibility policy has a long tradition but gained incre

In most of the industrial world the fractions of older people continuously increase (OECD, 2011). The upcoming demographic change is described as a threat to societal service. Many societies have to motivate people to work until an older age to increase the number of working hours in the economy (Eurostat, 2010). Factors important to whether older workers extend their working life are complex, mul

Abstract/Introduction:In most of the industrialized world, the proportion of older and retired people in the population is increasing.The active working part of the population must in a short future fund the not working and ageing population.There is research going on in Scandinavia to obtain knowledge about older workers’ work and life situationin association with their planning and decision to r

While the definition of extended conceptions of democracy has been widely discussed, the measurement of these constructs has not attracted similar attention. In this article we present new measures of polyarchy, liberal democracy, deliberative democracy, egalitarian democracy, and participatory democracy that cover most polities in the period 1900 to 2013. These indices are based on data from a la

Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem
