The ability of 32 purified and characterized hydrolyzable tannins to form insoluble complexes with model protein bovine serum albumin was investigated with a turbidimetric 96-well plate reader ...method. The results showed a clear relationship between the hydrolyzable tannin structure and the intensity of haze that formed during the tannin–protein complexation. In addition to molecular weight, structural features such as number of galloyl groups, degree of oxidative coupling between the galloyls, positional isomerism, and cyclic vs acyclic glucose core were the major structural features that affected the ability of the monomeric hydrolyzable tannins to form insoluble complexes with bovine serum albumin. While oligomers were superior to monomers in their capability to precipitate the model protein, their activity depended less on the functional groups, but mostly on their size and overall flexibility. These results allowed us to construct an equation that predicted the protein precipitation capacity of the studied hydrolyzable tannins with high accuracy.

Abstract
The focus of facility managers used to be mostly about buildings and services. In this new post-Covid world, facility managers play an important role related to people and services. As ...organizations make significant transitions to hybrid and remote work, facilities management can ensure by its behalf that employees have productive and fulfilling relationships with their co-workers, their organizations, and their workplaces. The purpose of this paper is to identify short-, medium- and long-term professional challenges to facilities management profession caused by an increase in multilocational work. The short-term challenges may be temporary by nature, and they are based on the explorations of multilocational work. The medium-term challenges are based on a more permanent and stable situation. Long-term challenges are more fundamental by nature reflecting the constant transformation of people, processes, and buildings. The qualitative data were gathered from focus group discussions with Facilities Management professionals from five different continents. The data were organized in three different analyses. The short-term, medium-term, and long-term challenges were identified. The findings indicate that the role of a facility manager is becoming more prominent, and the facility manager should perceive this crisis as an opportunity to step up and support the organisation in its strategic policy. Facilities managers should position themselves as the liaison between the physical and the digital worlds so that they are valuable stakeholders in this emerging virtual space. The results of this study contribute to the development of facilities management training and professional development and shed light on future research needs for the profession.
The Solar Intensity X-ray and particle Spectrometer (SIXS) on the BepiColombo Mercury Planetary Orbiter (“Bepi”) measures the direct solar X-rays, energetic protons, and electrons that bombard, and ...interact with, the Hermean surface. The interactions result in X-ray fluorescence and scattering, and particle induced X-ray emission (PIXE), i.e. “glow” of the surface in X-rays. Simultaneous monitoring of the incident and emitted radiation enables derivation of the abundances of some chemical elements and scattering properties of the outermost surface layer of the planet, and it may reveal other sources of X-ray emission, due to, for example, weak aurora-like phenomena in Mercury’s exosphere. Mapping of the Hermean X-ray emission is the main task of the MIXS instrument onboard BepiColombo. SIXS data will also be used for investigations of the solar X-ray corona and solar energetic particles (SEP), both in the cruise phase and the passes of the Earth, Venus and Mercury before the arrival at Mercury’s orbit, and the final science phase at Mercury’s orbit. These observations provide the first-ever opportunity for in-situ measurements of the propagation of SEPs, their interactions with the interplanetary magnetic field, and space weather phenomena in multiple locations throughout the inner solar system far away from the Earth, and more extensively at Mercury’s orbit.
In this paper we describe the scientific objectives, design and calibrations, operational principles, and scientific performance of the final SIXS instrument launched to the mission to planet Mercury onboard BepiColombo. We also provide the first analysis results of science observations with SIXS, that were made during the Near-Earth Commissioning Phase and early cruise phase operations in 2018–19, including the background X-ray sky observations and “first light” observations of the Sun with the SIXS X-ray detection system (SIXS-X), and in-situ energetic electron and proton observations with the SIXS Particle detection system (SIXS-P).
The United Nations Sustainable Development Goals (SDGs) work as a new agenda for sustainable development globally. Many if not most of the SDGs can be combined with different levels of education. ...This paper leans on previous work in Sustainable Education Design (SED), which looked at sustainability from its multifaceted angles with a broad global scope. The context of the study is a campus at a research-intensive Finnish university. The methodology entailed participatory service design approaches. For piloting, one classroom was chosen as a test bed. The data consist of workshops, use walks and structured interviews. The analysis started from identifying KPIs of sustainable learning environment creation, after which these were tested against Sustainable Education Design Criteria described in a manual book earlier. The key findings include nine preliminary alternative KPIs that were merged with previous SED criteria and related SDGs. The alternative KPIs were trialled in the test bed environment. These proposed alternative KPIs can be used as indicators for sustainability, innovation and learning during participatory change processes and in evaluating the outcome.
Green Bonds are an instrument for driving the environmentally friendly and low-carbon economy. Green Bonds are bonds whose proceeds are earmarked for and transparently channelled to ...environmentally-friendly projects and activities. The real estate industry has a multi-decade track record of addressing environmental impacts through the use of rating systems certified by independent third parties. Green building certification systems address multiple environmental impacts and measure outcomes across all asset lifecycle phases. Using bonds for such investments is not new but in an effort to improve transparency and increase opportunities both for issuers and investors it can take a more active role in combating climate change. The goal of this paper is to describe how property developer can use Green Bond as one instrument in sustainable life cycle management and continuous development of properties. The method used is a case study of Finnish property owner company, which commits to invest the funds raised in certified, environmentally responsible and energy-efficient projects. The single case study method employed in this study captured the process of case organization towards Green Bond initiative. More precisely the data was gathered by qualitative document analysis (QDA). The results show that company begin the process with focusing on environmental sustainability especially putting the effort in the first phase to energy efficiency. The Green Bond initiative provided a new avenue towards economic sustainability. Additionally, issues like shared use of facilities was discussed from social sustainability perspective. The results are interesting for property owners who are interested in systematic development towards regenerative built environment.
Companies operating in the industrial sector are increasingly outsourcing some of their operations to provider companies. Outsourcing involves external workforces and workplaces and forms new kinds ...of work communities with complex relationships between different performers. The new operating environment introduces safety problems, which are particularly difficult to manage for providers that commonly operate with several customers in varying worksites. This paper discusses the results of a literature review focusing on the safety management problems encountered by industrial service providers. The factors most commonly mentioned as problems for service providers in management of safety are ignoring tendering systems, divergences in customers and worksites, time pressures, poor resource available for implementation of safety measures, unclear responsibilities, dangerous work tasks, inadequate communication, and insufficiencies in hazard identification. Even though several problems have been identified, the practical means presented to improve safety by the provider companies are still exiguous.
There is a keen interest in marketing to move away from the neo-classical market definition suggesting that markets are places where demand and supply meet to reach equilibrium. In the present study, ...markets are defined as configurations of interdependent elements (market actor's mental models, market actor's business models, market practices) that make an increased density of resources, capabilities and value co-creation possible for the participating actors. The findings of the research indicate that firms can actively alter market configurations by engaging in market scripting: offering market propositions that illustrate their view on how the market should be configured and engaging actors in activities aimed at creating a shared market view. In market scripting the scripting actor aims to align the mental models and business models of other market actors so that they reinforce the mental and business models of the scripting actor and increase the ‘marketness’ of the market configuration.
We have fabricated and tested a thin silicon detector with the specific goal of having a very good thickness uniformity. SOI technology was used in the detector fabrication. The detector was designed ...to be used as a ΔE detector in a silicon telescope for measuring solar energetic particles in space. The detector thickness was specified to be 20μm with an rms thickness uniformity of±0.5%. The active area consists of three separate elements, a round centre area and two surrounding annular segments. A new method was developed for measuring the thickness uniformity based on a modified Fizeau interferometer. The thickness uniformity specification was well met with the measured rms thickness variation of 43nm. The detector was electrically characterized by measuring the I–V and C–V curves and the performance was verified using a 241Am alpha source.
Concentrations and fluxes of greenhouse gases methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) were measured during open water conditions in two hydroelectric reservoirs, Lokka and ...Porttipahta, in the northern boreal zone in Finland. These reservoirs were located on peat and forest soils and were built in 1967 and 1970, respectively. Over 20 years after their flooding, the reservoirs were still largely supersaturated with dissolved CH4 and CO2. Measured with floating static chambers, the stations in Lokka released more CH4 (means of 5.3–119 mg m−2 d−1) during the open water periods in 1994 and 1995 than the stations in Porttipahta (means of 2.5–4.8 mg m−2 d−1), measured in 1995. The mean CO2 emission rates in Lokka (21–133 mg m−2 h−1) and Porttipahta (36–95 mg CO2 m−2 h−1) were more similar. The chamber measurements could not detect episodic CH4 ebullition in Lokka Reservoir, indicated by generally higher CH4 fluxes (means of 2.6–660 mg m−2 d−1) obtained with bubble gas collectors than with the chambers. The seasonal mean N2O fluxes were generally low, ranging from −89 to 270 μg m−2 d−1. There was no clear association between the CH4 emissions and the bottom type, including mineral soils and old peat deposits. The flooded vegetation, higher nutrient content, and primary production in the water column rather than old peat could account for the higher CH4 emissions from the stations in Lokka. This conclusion is supported by the high content of modern carbon (C) in methane (percent modern C of 92–104%) that was extracted from the sediment of Lokka. The results suggested that if there is a good long‐term availability of phosphorus and nitrogen, the intensive internal C cycle associated with the primary production could maintain high CH4 and CO2 production for decades, similar to the situation in eutrophied natural lakes.
