The purpose of this study is to describe how the greenhouse gas (GHG) benefits of ethanol from agricultural crops depend on local conditions and calculation methods. The focus is mainly on the fuels used in the ethanol process and biogenic GHG from the soils cultivated. To ensure that "good" ethanol is produced, with reference to GHG benefits, the following demands must be met: (i) ethanol plants

From the starting point of narrative ethnography, this article explores a specific kind of service user involvement in psychiatry: staff training activities in which patients and former patients are invited to “tell their stories”. A core feature of these stories is that they are based on the narrators’ self-perceived experience, and they all have a highly personal character. I call these stories

Infertility, defined as the inability to conceive after one year of unprotected regular intercourse, affects up to 15% of all couples of reproductive age. The infertility can originate from female, male or both partners. In up to 50% of the affected couples, a male factor is the cause of infertility. Semen analysis is the cornerstone of male infertility assessment and an abnormal result often trig

This paper proposes a typology for provider roles in defining business services. The starting point of the study is the underlying rationale of much of the service purchasing literature that buyers have or can easily access the necessary know-how to procure business services. If this does not hold, the implication is that buying firms would shy away from buying complex services. An alternative per

The Atankwidi River Basin is situated in the Upper East Region of Ghana. The Basin has an area of around 275 km2. The semiarid climate in which the Atankwidi is situated is characterized by one rainy season spanning from April to September and one dry season spanning from September to April. All of the year’s precipitation falls during the rainy season – roughly 1000mm – with a peak downfall in Au

Through a recent line of landmark judgments, the European Court of Justice has widened the scope of application of the freedom of establishment under the EC Treaty. It is now clear that the said freedom does not only convey upon undertakings the right to form subsidiaries or branches abroad&semic it also gives them the right to incorporate in one Member State only to conduct all their business

The purpose of this essay was to investigate how multiproblematic families get in contact with treatment units offering family therapy in Lund and especially which theories and methods the therapists use. To pursue this study, literature was searched in libraries, on the internet and six persons, working therapeutic with families in six different treatment units, were interviewed. The result of th

After World War II Sovjet took over Poland with the plan of making it a socialist state in all its meanings, religious as well. That meant changing it from Roman Catholic to secular which turned out to be harder than expected because of the position of the church. The church was a symbol of the nation and a savior of the people and the communist party understood that this would be a process of tra

Virtual reality (VR) has provoked enormous interest in the medical community. In particular, VIR offers therapists new approaches for improving rehabilitation effects. However, most of these VR assistant toots are not very portable, extensible or economical. Due to the vast amount of 3D data, they are not suitable for Internet transfer. Furthermore, in order to run these VR systems smoothly, speci

Strain-induced tendinopathy is a common injury in both human and equine athletes, with increasing incidence associated with greater involvement in sport and an increasingly aged population. This paper reviews our studies on the abundant non-collagenous protein, cartilage oligomeric matrix protein (COMP), in equine tendons. Its variation between tendon type and site, age and exercise has provided a

Popular Abstract in English For several decades the electronic industry has developed towards smaller and smaller electronic components. The idea behind this development is quite simple: Small components have faster response times, which enables faster devices. Also, smaller components make it possible to decrease the size of the devices. A common example is today's mobile phones, that actually arThis dissertation deals with the effects of coherence and correlations on transport through nanostructures. Simulations are mainly performed using the second order von Neumann approach, a method capable of dealing with these effects in the presence of higher order tunneling. We see that such effects can result in various kinds of current suppression as well as efficient thermoelectric devices. Fu

The adsorption of ethylene at 100 K on clean and oxygen precovered Pd(1 1 1) surfaces and the thermal evolution of the ethylene adsorbate layers have been investigated experimentally by high-resolution electron energy loss spectroscopy (HREELS), high-resolution X-ray photoelectron spectroscopy with synchrotron radiation, thermal desorption spectroscopy and theoretically by ab initio density functi

Substrates present in aggregated forms, such as micelles, are often poorly converted by enzymes. Alkyl glycosides constitute typical examples and the critical micelle concentration (CMC) decreases with increasing length of the alkyl group. In this study, possibilities to hydrolyse alkyl glycosides by glycoside hydrolases were explored, and α-cyclodextrin was used as an agent to form inclusion comp

This study (N = 102 women) evaluated the time course of posttraumatic stress symptomatology (PTSS) at different stages of nonmetastastic cancer diagnosis and treatment: during treatment, at the end of treatment, and at a 6-12 months follow-up. We also assessed the contribution of demographic, trait, and state predictors to PTSS, and coping processes as proximal mediators of the relation between Ty

We consider the problem of how to schedule t similar and independent tasks to be performed in a synchronous distributed system of p stations communicating via multiple-access channels. Stations are prone to crashes whose patterns of occurrence are specified by adversarial models. Work, defined as the number of the available processor steps, is the complexity measure. We consider only reliable algo

As the highest level of cloud computing delivery model, Software-as-a-Service (SaaS) has gained considerable popularity in the industry as a new way of deploying IT solutions, due to its low cost and high elasticity. However, the new business model associated with SaaS highlights the importance for SaaS vendors to understand how to retain customers in a hyper-competitive market. In particular, inc

Whilst it is increasingly recognised that socio-political contexts shape climate change adaptation decisions and actions at all scales, current modes of development typically fail to recognise or adequately challenge these contexts where they constrain capacity to adapt. To address this failing, we consider how a rights-based approach broadens understanding of adaptive capacity while directing att

Why did France experience the demographic transition first? This question remains one of the greatest puzzles of economics, demography, and economic history. The French pattern is hard to reconcile with elucidations of the process as found in other countries. The present analysis goes back to the roots of the process and offers novel ways of explaining why people started to control their fertility
