Mixed cultures of a heterotrophic nitrifier/aerobic denitrifier, Thiosphaera pantotropha, and an autotrophic nitrifier, Nitrosomonas europaea, were grown in chemostats under dual ammonia-and acetate limitation. Because of simultaneous nitrification and denitrification by T. pantotropha, the activity of the cultures was evaluated from nitrogen balances as complete as possible. Under most conditions
Despite impressive advances in theories, methods and technologies, crystallization still remains a serious bottleneck in structural determination of macromolecules. Here we present a novel solid-liquid interface method (SLIM) for protein crystallization, based on the pre-adding and drying of a crystallization reagent, and thereafter the dispensing of a protein solution to the dried media to initia
As part of a structural genomics platform in a university laboratory, a low-cost in-house-developed automated imaging system for SBS microplate experiments has been designed and constructed. The imaging system can scan a microplate in 2-6 min for a 96-well plate depending on the plate layout and scanning options. A web-based crystallization database system has been developed, enabling users to fol
To facilitate the justification of an X-ray or nuclear medicine investigation and for informing patients, it is desirable that the individual patient's radiation dose and potential cancer risk can be prospectively assessed and documented. The current dose-reporting is based on effective dose, which ignores body size and does not reflect the strong dependence of risk on the age at exposure. Risk es
Public clouds such as Amazon Web Services (AWS) and Microsoft’s Azure provide excellent capabilities for scalable Web applications and Hadoop-based processing. Recent ad- ditions to public clouds to support connected devices and IoT have the potential to similarly disrupt emerging home- grown and/or proprietary approaches. While early public cloud IoT success stories have focused on smaller-scale
The collection of chapters in this book present the concept of matched filters: Response characteristics “matching” the characteristics of crucially important sensory inputs, which allows detection of vital sensory stimuli while sensory inputs not necessary for the survival of the animal tend to be filtered out, or sacrificed. The individual contributions discuss that the evolution of sensing syst
We argue that social robots should be designed to behave similarly to humans, and furthermore that social norms constitute the core of human interaction. Whether robots can be designed to behave in human-like ways turns on whether they can be designed to organize and coordinate their behavior with others’ social expectations. We suggest that social norms regulate interaction in real time, whereage
Object: To present population-based and age related incidence of surgery and clinical outcome for adult patients operated for hydrocephalus, registered in the Swedish Hydrocephalus Quality Registry (SHQR). Methods: All patients registered in SHQR during 2004–2011 were included. Data on age, gender, type of hydrocephalus and type of surgery were extracted as well as three months outcome for patient
A new detailed kinetic mechanism for formaldehyde and methanol combustion has been developed using the Konnov mechanism, version 0.6, as a starting point. In total, 82 reactions of the formaldehyde and methanol subsets were reviewed and updated using a systematic approach. Rate constants were selected based on thorough evaluation of available experimental and theoretical data. No modifications of
In this article, gas-phase advanced oxidation, a new method for pollution control building on the photo-oxidation and particle formation chemistry occurring in the atmosphere, is introduced and characterized. The process uses ozone and UV-C light to produce in situ radicals to oxidize pollution, generating particles that are removed by a filter; ozone is removed using a MnO2 honeycomb catalyst. Th
The banana pseudo-stem is a low-lignin-content lignocellulosic biomass that can be used for methane production. In recent years, anaerobic digestion (AD) of dried banana stems for methane production has attracted considerable attention. However, there is limited information regarding methane production from the fresh banana pseudo-stem. The direct usability of fresh banana stems as a resource for
The South American Altiplano in the Andes is, aside from Tibet, the most extensive high plateau on Earth. This semiarid area represents important water resources storages, including the Lakes Titicaca and Poopó located in the northern and central Altiplano, respectively. The two lake basins and the southern saltpans constitute a large watershed, called the Lake Titicaca, Desaguadero River, Lake Po
Background: Diabetes remission is an important outcome after bariatric surgery. The purpose of this study was to identify risk prediction models of diabetes remission after bariatric surgery. Methods: A systematic literature review was performed in MEDLINE, MEDLINE-In-Process, Embase and the Cochrane Central Register of Controlled Trials databases in April 2015. All English-language full-text publ
This paper suggests an infrastructure perspective, as suggested by Star and Bowker (2006), as an analytical framework for studying the research evaluation landscape. An infrastructure is suggested to be understood, not as a concrete technology, but as a system of contextual factors including ‘Actors/Stakeholders’, ‘Technical systems’, and ‘Evaluation practices’. How the framework can be operationa
Introduction: CD40 signaling activates dendritic cells leading to improved T cell priming against tumor antigens. CD40 agonism expands the tumor-specific T cell repertoire and has the potential to increase the fraction of patients that respond to established immunotherapies. Areas covered: This article reviews current as well as emerging CD40 agonist therapies with a focus on antibody-based therap
