Mycket har gjorts när det gäller tydligare regler och information kring hur avfallet ska omhändertas men det som brister är den praktiska hanteringen vid rivning av byggnader. En huvudorsak är att det är svårt att identifiera CFC vid rivning samt att det är dyrt att transportera och destruera stora rivningsmassor. Det…

A microbial fuel cell (MFC) is a device capable to convert chemical energy to electrical energy by using microorganisms. Typically, microbial fuel cell is recognized with its dual chamber system. In this dual chamber system, the membrane acts as the separator that divides anode and cathode as the cell compartment. One…
Die wichtigsten Lichtwellenlängen für Telekommunikationssysteme sind momentan 1310 nm und 1550 nm. Dies liegt vor allem an der geringen Dämpfung, der zurzeit verwendeten Glasfasermaterialien, bei diesen Wellenlängen. Um moderne Multiplexverfahren (wie z.B. dem Dichte-Wellenlängen-Multiplex-Verfahren (DWDM)) verwenden…
Here we compare the growth temperature dependence of the response of LaTiO3/SrTiO3 and LaAlO3/SrTiO3 2D-electron gas (2-DEG) field effect structure to the optical radiation of near ultraviolet frequency and electrostatic gate field. For both the films the resistance of the channel increases significantly as growth tem…
I ett modernt samhälle är elektricitet en nyckelkomponent för industrins, individens och samhällets utveckling. Naturkatastrofområden där elektriciteten slagits ut står inför stora prövningar för att kunna få samhällsviktiga funktioner att fungera igen. Med hjälp av den mobila miljövänlig energienhet Emergency Energy…
urface plasmon resonance (SPR) is a powerful tool in probing interfacial events in that any changes of effective refractive index in the interface directly impact the behavior of surface plasmons, an electromagnetic wave, travelling along the interface. Surface plasmons (SPs) are generated only if the momemtum of inci…
The present study relates to the field of ceramic powders. Particularly, it relates to a process for producing the graphite - silicon carbide (SiC) micro-composite ceramic powders by carbo-thermal reduction. Silicon carbide is a ceramic material valued mainly for its high resistance to thermal stress and shock and its…
Tungsten nanopowder with elementary sulfur combustion rate and conversion ratio in combustion wave dependence on argon pressure and on sulfur excess under constant pressure were studied. Synthesis was self-propagating high temperature synthesis (SHS). Stoichiometric mixture combustion process photographs based on whic…
In questo lavoro e presentata la simulazione del processo di riscaldo per austenitizzazione di grandi fucinati in acciaio destinati alla tempra differenziale. In ogni trattamento termico, le grandezze controllabili a livello industriale sono il tempo e la temperatura. E quindi agendo su queste che si puo ottimizzare i…
HaswellCorei3不论是在处理器性能，还是整合的核芯显卡性能上，较上一代同类产品都有明显的提升。为此，主板厂商也特别针对此类处理器，推出了不少采用B85、H81等芯片组的主流主板，如这款由映泰设计的Hi-FiB85S3＋。
SINGLE-STRANDED DNA SCANNING AND DEAMINATION WITH SINGLE-MOLECULE RESOLUTION by GAYAN SENAVIRATHNE December 2013 Advisor: Dr. David Rueda & Dr.Ashok Bhagwat Major: Chemistry (Analytical) Degree: Doctor of Philosophy APOBEC3G (Apo3G) and Activation-Induced cytidine Deaminase (AID) are the most notable members of APOBEC…
Nuclear power plants require advanced materials that can withstand radiation damage for decades while maintaining structural integrity. Silicon Carbide (SiC) is one such material currently being studied due to its notable strength and hardness, making it a viable material to be used in nuclear reactors. Recent researc…
Metamaterials have a wide range of potential uses in areas such as optics, transmission lines, communication and RF design. The simplest metamaterial structures are composite right/left handed tran ...
In the previous two chapters I briefly skimmed over the basics of state machine workflows. This chapter will quickly have you building state machine workflows to model some really cool scenarios, but before we get going, let’s review the basics.
Energi nuklir sipil semakin hari dapat menjadi jawaban bagi kebutuhan energi di sebuah negara. Dengan adanya perkembangan dalam mengelola energi nuklir sipil ini, maka setiap negara berusaha untuk menemukan sebuah teknologi dalam pengelolaannya. Ini dikarenakan perkembangan teknologi dapat menjamin keamanan dalam peng…
The analysis of work of mechanical VIT system (Variable Injection Timing) of the marine low-speed diesels MAN B&W of MC series is given. Features of VIT are given. By the example of the ship low-speed main diesel 6L80MCE influence of VIT on the diesel working process is shown. The general signs of late fuel injection…
Positive effects of ultrasound on crystallization have been known for almost 90 years. Application of ultrasound has been very successful in many industries, most notably in chemistry, creating a new branch of science - sonochemistry. However, ultrasonication has not found wide commercial application in the solidifica…
