Ripening of dry cured ham involves a high number of complex enzymatic and chemical reactions. Due to long processing time, there is a need for analytical methods that can be applied to monitor the ripening in optimization of process conditions and development of new products. In this study, nontargeted metabolite analysis by mass spectrometry (MS) was employed to determine the ripening rates at different water activities in small-scale laboratory experiments and to follow the progress of the ripening of hams from a dry cured ham production facility. Approximately 1000 metabolites were detected. Of these, 90–95% had molecular masses below 800 Da, and more than 60% below 500 Da. In the order of 150 metabolites were putatively annotated. In addition to free amino acids and muscle metabolites, the nontargeted analysis revealed the time profiles of di- and tripeptides, as well as a high number of compounds generated by further conversion of amino acids, muscle metabolites and probably lipids. Statistical processing of the data sets showed that the metabolite profiles changed with the storage time, and that ripening of fresh and unsalted, dried meat, generated other profiles than salted samples. In conclusion, our approach represents a simple and efficient tool for comparison of process conditions and to follow the time course of the ripening, useful in product development and process optimization. 相似文献

Examinations of living labs are scarce even though the approach is increasingly used as an opportunity to bring design activities into real-life use context and consequently facilitate cooperations between designers and users in future technology innovation. Furthermore, examinations of living labs that focus on the people living in the labs do not exist. This paper presents a study of eight living labs set up in care homes for innovation in health technologies and focuses on the work carried out by care workers, service staff, residents and management, i.e. people living and working in the labs. The analysis reveals a comprehensive system of work carried out by people living and working in the labs and identifies that linking the lab-work-system to the ongoing existing work-system is a major challenge. The study demonstrates that the work of people living and working in the labs is critical to the success of living labs and recommends greater focus on work balance, user gains and collaborative innovation in living lab theories and methods. 相似文献

Titanium dioxide (TiO2) was deposited on polymethylmethacrylate (PMMA) substrates by magnetron sputtering using a Compact Planar Magnetron sputtering device at different flow rate ratios of O2/Ar. The deposited TiO2 on PMMA substrates were characterized using X-ray Diffraction analysis, X-ray Photoelectron Spectroscopy, Fourier Transform Infrared Spectroscopy, UV-Visible Spectroscopy, and Scanning Electron Microscopy (SEM). These techniques confirm the deposition of a chemically stable amorphous TiO2 layer on the PMMA surface. Photocatalytic activity of the amorphous TiO2 layers were tested via photodegradation of Rhodamine 6G (Rh6G) dye solution. The samples were able to degrade 18–27% of the Rh6G solution after the initial 25 minutes of UV irradiation and complete degradation of Rh6G was observed after 7 hours of UV irradiation. 相似文献

We examined the cognitive processes that might account for the impact of cross-group friendship on novel intergroup situations. Study 1 demonstrated that closeness with outgroup members predicts an association of the outgroup with the self, both in terms of the group itself and the personality traits stereotypically associated with the group. In Studies 2 and 3, we manipulated the accessibility of either a same-group friendship or cross-group friendship. Participants who described a cross-group friend exhibited a greater association of the friend's ethnicity with the self, and this association mediated the effects of friendship accessibility on positive expectations for intergroup contact (Study 2) and adaptive hormonal responses during a real interaction with a novel outgroup member (Study 3). These findings imply that cross-group friendship improves novel intergroup experiences to the degree that outgroups become associated with the self.

The Department of Physics at Lund University is participating in a European Union project called EUMAPP (European Union Microdose AMS Partnership Programme), in which sample preparation and accelerator mass spectrometry (AMS) measurements of biological samples from microdosing studies have been made. This paper describes a simplified method of converting biological samples to solid graphite for 14C analysis with AMS. The method is based on online combustion of the samples, and reduction of CO2 in septa-sealed vials. The septa-sealed vials and disposable materials are used to eliminate sample cross-contamination. Measurements of ANU and Ox I standards show deviations of 2% and 3%, respectively, relative to reference values. This level of accuracy is sufficient for biological samples from microdosing studies. Since the method has very few handling steps from sample to graphite, the risk of failure during the sample preparation process is minimized, making the method easy to use in routine preparation of samples. 相似文献

New families of monomeric to dendritic, and monocationic to multicationic (PNP) compounds have been prepared and tested as catalysts in halogen exchange (Halex) reactions. Some of them allow an increase in the efficiency of these reactions which are performed in some cases under the mildest conditions reported up to now. 相似文献

With the increasing need for intelligent environment monitoring applications and the decreasing cost of manufacturing sensor devices, it is likely that a wide variety of sensor networks will be deployed in the near future. In this environment, the way to access heterogeneous sensor networks and the way to integrate various sensor data are very important. This paper proposes the common system for middleware of sensor networks (COSMOS), which provides integrated data processing over multiple heterogeneous sensor networks based on sensor network abstraction called the sensor network common interface. Specifically, this paper introduces the sensor network common interface which defines a standardized communication protocol and message formats used between the COSMOS and sensor networks. 相似文献

An Fe3O4/Cu nanostructured prototype electrode was developed from a 100% bottom‐up approach thanks to an original three‐step electrodeposition procedure that enlists 1) the growth of a ZnO nanocolumnar template, 2) the filling of the template voids by copper prior to the dissolution of the zincite nanopillars, and 3) the plating on the remaining copper nanodots of the Fe3O4 phase. The key technological point is that ZnO readily forms nanorod arrays by self‐assembly when an aqueous solution of ZnII, saturated by dioxygen, is cathodically polarized. The as‐obtained inorganic solid template is sufficiently stable for further deposition steps of any kind (metals, oxides, polymers, and so on) but is easy to remove in both acidic and alkaline media. The self‐supported Fe3O4/Cu nanostructured electrode shows, besides sustained capacity retention, outstanding rate capability when electrochemically tested versus Li. This original and soft process, derived from template‐assisted synthesis, avoids fixing (mechanically) a nanoporous membrane on the substrate, thus, enabling nanostructural design on shapeless surfaces. 相似文献
