description: The effective spin exchange coupling between impurities (adatoms) on graphene mediated by conduction electrons is studied as a function of the strength of the potential part of the on-site energy $U$ of the electron-adatom interaction. With increasing $U$, the exchange coupling becomes long-range, determined largely by the impurity levels with energies close to the Dirac points. When adatoms reside on opposite sublattices, their exchange coupling, normally antiferromagnetic, becomes ferromagnetic and resonantly enhanced at a specific distance where an impurity level crosses the Dirac point.

description: This study aims to decipher the structural evolution of a sector of the Nappe Zone in the Sardinian Variscan Belt. We investigated the Barbagia Thrust between the Meana Sardo Unit (belonging to the External Nappe Zone) in the footwall and the Barbagia Unit (belonging to the Internal Nappe Zone) in the hanging wall. Combining the geological survey with meso- and microstructural analysis, we realized a 1:10.000 scale geological map highlighting the polyphasic evolution developed under low-grade metamorphic conditions during the Variscan orogeny. Both units preserve (i) an early phase generally observed far from the tectonic contact and mainly in the Meana Sardo Unit (D1), (ii) a syn-nappe ductile deformation linked to the Barbagia Thrust activity and a top-to-the S-SW sense of shear (D2) and (iii) a large-scale nappe refolding (D3). A late extensional stage (D4), with the development of collapse folds, marks the end of the orogenic cycle.

description: Abstract Objective: The objectives of this study were to assess the oral health status and parental perception of oral health needs of pediatric patients with craniofacial anomalies in an urban American craniofacial center. Design: This research utilized a cross-sectional matched study design. The data was collected prospectively via clinical oral examinations and evaluation criteria included dental caries experience oral hygiene status, and gingival health status. Setting: The study was conducted at two different sites which included the Pediatric Dentistry Department, College of Dentistry (COD), UIC and the University of Illinois Health (UI Health) Craniofacial Center (CFC) Patients/Participants: Participants were recruited from UI Health CFC and UIC COD. Main Outcome Measure(s): The outcome measures were the oral health status and parental perception thereof. Results: CFC patients showed high rate of caries experience in primary teeth that was significantly lower than that of a healthy matched cohort, but statistically similar in permanent teeth.. CFC patients had significantly higher unmet dental treatment . CFC patients had poor oral hygiene and were shown to have significantly higher plaque levels than that of a healthy matched cohort. Other metrics of oral health and parental perception of oral health were not statistically significant. Conclusions: Patients in our study in an urban CFC were found to have a higher unmet dental and worse oral hygiene. Despite the oral health statues being worse, parents of children with craniofacial anomalies did perceive their oral health as different from a matched cohort of patients without these conditions.

description: Strategic management is the larger, more holistic process that encompasses the planning, implementation, evaluation, and updating of a strategic agenda aimed at maintaining the most viable fit between an organization and its external environment and moving into the future in a deliberate, purposeful manner. Successful cultural change results from having a clear idea about what type of culture the business needs, identifying the specific attributes that go along with it, and then focusing on managing the drivers that shape and influence culture which is of paramount importance for effective and efficient execution of strategies. Strategic management and supply chain are not separable aspects. Hence, instilling strategy management culture in the supply, if applies lean-kaizen approach, results in competitive performances. The tools of strategic management: Balanced scorecard and Hoshin Kanri can make this possible. The paper illustrated the moderating effect of strategy management culture on the relationship between lean-kaizen supply chain and competitive performances. The study showed they are positively related and the moderator also has positive interaction effect on this relationship. Thus, it possible to instill strategy management culture in the lean-kaizen supply chain through balanced scorecard and hoshin kanri integration. Keywords: Strategic Management, Strategy Management Culture, Balanced Scorecard, Hoshin Kanri, Lean-Kaizen

description: Detailed sedimentological studies of the university main campus of São Paulo city, Brazil, revealed a significant unconformity at the top of the Cenozoic sedimentary deposits of the São Paulo Formation. This unconformity is overlapped by Quaternary sediments which can be traced in 1:20,000 scale and are here named as the Bosque Formation. This unit is characterized by poorly sorted mud deposits and very fine-grained red sand with granule- and pebble-sized clasts of the underlying São Paulo Formation. Furthermore, it overlies topographic highs of the Precambrian basement, and is laterally interfingered with fluvial terraces; it is eroded by the modern river at the lower reaches of the outcrops. The Bosque Formation records sedimentation characterized by a widespread mudflow that overlays old alluviums sediments, and was likely deposited during the beginning of the Holocene.

description: Introducing, observing, and manipulating individual impurities coupled to a host material offers the opportunity to create new device concepts based on single spin and charge states. Because of potential applications in spintronics and magneto-electrics, such an approach would be particularly useful for topological insulators (TI), a recently discovered material class hosting spin-momentum- locked surface states. To make them useful for new technologies, a robust control of their interaction with external perturbations is required. However, traditional approaches such as metal electrodes or doping proved to be problematic and resulted in strong mesoscopic fluctuations making the spin-momentum locking ill-defined. Here, we demonstrate the effective gating of TIs by coupling molecules to their surface which, by using electric fields, allow to dynamically control the interface charge state by adding or removing single electrons. This process creates a robust transconductance bistability resembling a single-electron transistor. Our findings make hybrid molecule/TI interfaces functional elements while at the same time pushing miniaturization at its ultimate limit. This opens a new avenue for all electric-controlled spintronic devices based on these fascinating materials.

Year: 2018

description: The purpose of this study was to investigate the role of employees' engagement on their turnover intentions: the case of Commercial Bank of Ethiopia. The study used quantitative research method and employed both descriptive and explanatory research design to objectively answer the proposed research questions. To achieve the study objective, 368 sample respondents were selected through multistage sampling technique. Accordingly, data were collected through self-administered questionnaire from sample respondents. Out of 368 respondents, workable data were obtained from 335 respondents. The data, then, analyzed through descriptive, inferential statistics and independent samples T test. The finding of descriptive analysis revealed that more than half percentage of employees are under the category of neither engaged nor disengaged, and the mean score for the overall turnover intentions of employees is slightly above average. The independent samples T test revealed that both employees' engagement and turnover intentions levels of employees significantly differ across five employees' demographic characteristics (experience, age, gender, educational qualification and income) of employees. The spearman's correlation analysis result showed that there is a significant strong negative relationship exists between employees' engagement and turnover intentions. Among the dimensions dedication dimension has a very strong negative relationship with turnover intentions. Moreover, the ordinal regression analysis evidenced that both employees engagement dimensions are a significant predictors of employees turnover intentions, among them dedication dimension is a unique contributor for employees turnover intention; also the overall employees' engagement is a statistically significant predictor of turnover intentions of employees. Furthermore, on the basis of the research findings, appropriate recommendations for practice along with directions for further studies have been forwarded. Keywords: Employees' Engagement, Vigor, Dedication, Absorption, Turnover Intentions.

description: The ability to reason beyond established knowledge allows Organic Chemists to solve synthetic problems and to invent novel transformations. Here, we propose a model which mimics chemical reasoning and formalises reaction prediction as finding missing links in a knowledge graph. We have constructed a knowledge graph containing 14.4 million molecules and 8.2 million binary reactions, which represents the bulk of all chemical reactions ever published in the scientific literature. Our model outperforms a rule-based expert system in the reaction prediction task for 180,000 randomly selected binary reactions. We show that our data-driven model generalises even beyond known reaction types, and is thus capable of effectively (re-) discovering novel transformations (even including transition-metal catalysed reactions). Our model enables computers to infer hypotheses about reactivity and reactions by only considering the intrinsic local structure of the graph, and because each single reaction prediction is typically achieved in a sub-second time frame, our model can be used as a high-throughput generator of reaction hypotheses for reaction discovery.

Publisher: name: University of Illinois at Chicago
Year: 2023

description: With the development of modern information technologies, nowadays a tremendous quantity of data is being collected with the potential to enhance our lives, and technologies and to offer people unprecedented scientific breakthroughs. On the other hand, the enormous scale of datasets presents new difficulties in analyzing them. Recently, various data reduction methods have been proposed to address the issue of excessive data volume. However, how does one measure the performance and statistical efficiency, of a selected method accurately? An ideal solution is to derive an optimal subdata. Unfortunately, as a typical NP-hard problem, given the large size of full data, it is infeasible to derive such optimal subdata. However, we can derive a nearly optimal subdata through Approximate Bounded Optimal Design (ABOD). In this dissertation, we aim to develop a general algorithm, the Group Exchange Algorithm, for ABOD. It can be used to select a nearly optimal subdata from any given full data set under both linear and non-linear models regardless of optimality criterion and parameters of interest. We also derive an equivalence theorem for ABOD and prove the convergence of the GE algorithm. Our simulation studies show that under different model settings, parameters of interest, size of the full data, and upper bounds for subdata selection, our algorithm keeps its outstanding performance compared to other methods.

Year: 2015

description: The purpose of this study was to investigate which factors affect the adoption of Internet banking in Addis Ababa. A conceptual frame work was developed based on factors in TAM, culture and perceived risk. Data was collected using questionnaire and distributed to a sample of 300 customers of three selected banks namely Dashen bank, Commercial bank of Ethiopia, and United bank. The collected data was analyzed using SPSS version 20.0 for descriptive analysis and the inferential analysis was analyzed using structural equation modeling. The findings of the study showed that perceived usefulness, perceived ease of use, attitude, perceived risk, and culture have a significant effect on intention to adopt Internet banking. In addition attitude is negatively and significantly related to perceived risk and positively and significantly related to perceived ease of use and perceived usefulness. Finally it is recommended to banks to improve their security policies, to make Internet banking more useful and useable, to concentrate on making their website user friendly, and government should also improve ICT infrastructure. Key words- Internet banking, TAM, Culture, Perceived Risk, Addis Ababa.

description: Landscape preservation strongly depends on exploration and knowledge of its history and evolution. The acquisition and the analysis of geological and geomorphological features are basic and useful tools to identify the touristic potential and the anthropic impact of a territory. This study aims to enhance the knowledge of the natural and cultural heritage of an area of the Daunia Mts between the towns of Alberona and Faeto, Southern Italy, marked by neglect and abandonment, through the drafting of a geomorphological map and the proposal of geotourist itineraries and routes. The results highlight the potential competitiveness and attractiveness of the study area by contributing to the promotion of a sustainable development of a marginal territory. Such data may encourage a form of fruition that promotes knowledge, appreciation, and environmental awareness, in a fragile territorial context.

description: Purpose – The wide application of metal material extrusion (MEX) has been hampered by the practicalities associated with the resulting shrinkage of the final parts when commercial three-dimensional (3D) printing equipment is used. The shrinkage behaviour of MEX metal parts is a very important aspect of the MEX metal production process, as the parts must be accurately oversized to compensate for shrinkage. This paper aims to investigate the influence of primary 3D printing parameters, namely, print speed, layer height and print angle, on the shrinkage behaviour of MEX Steel 316L parts. Design/methodology/approach – Two groups of dog-bone and rectangular-shape specimens were produced with the BASF Ultrafuse Steel 316L metal filament. The length, width and thickness of the specimens were measured pre- and post-debinding and sintering to calculate the percentile shrinkage rates. Analysis of variance (ANOVA) was used to evaluate and rank the significance of each manufacturing parameter on shrinkage. Typical main print quality issues experienced in this analysis are also reported. Findings – The shrinkage rates of the tested specimens ranged from 15.5 to 20.4% along the length and width axis and 18.5% to 23.1% along the thickness axis of the specimens. Layer height and raster angle were the most statistically significant parameters influencing shrinkage, while print speed had very little influence. Three types of defects were observed, including surface roughness, surface deformation (warping and distortion) and balling defects. Originality/value – This paper bridges an existing gap in MEX Steel 316L literature, with a focus on the relationship between MEX manufacturing parameters and subsequent shrinkage behaviour. This study provides an in-depth analysis of the relationship between manufacturing parameters – layer height, raster angle and print speed and subsequent shrinkage behaviour, thereby providing further information on the relationship between the former and the latter.
$\infty-\infty$: vacuum energy and virtual black-holes

description: We discuss other contributions to the vacuum energy of quantum field theories and quantum gravity, which have not been considered in literature. As is well known, the presence of virtual particles in vacuum provides the so famous and puzzling contributions to the vacuum energy. As is well known, these mainly come from loop integrations over the four-momenta space. However, we argue that these also imply the presence of a mass density of virtual particles in every volume cell of space-time. The most important contribution comes from quantum gravity $S^{2}\times S^{2}$ bubbles, corresponding to virtual black hole pairs. The presence of virtual masses could lead to another paradox: the space-time itself would have an intrinsic virtual mass density contribution leading to a disastrous contraction - as is known, no negative masses exist in general relativity. We dub this effect {\it the cosmological problem of second type}: if not other counter-terms existed, the vacuum energy would be inevitably destabilized by virtual-mass contributions. It would be conceivable that the cosmological problem of second type could solve the first one. Virtual masses renormalize the vacuum energy to an unpredicted parameter, as in the renormalization procedure of the Standard Model charges. In the limit of $M_{Pl}\rightarrow \infty$ (Pauli-Villars limit), virtual black holes have a mass density providing an infinite counter-term to the vacuum energy divergent contribution $M_{Pl} \rightarrow \infty$ (assuming $M_{UV}=M_{Pl}$). Therefore, in the same Schwinger-Feynman-Tomonaga attitude, the problem of a divergent vacuum energy could be analogous to the {\it put-by-hand} procedure used for Standard Model parameters.

description: This study presents the map of the external effective annual dose rate (1:200,000 scale) due to terrestrial and cosmic radiation. The terrestrial dose is assessed via gamma ray spectroscopy combining radiometric data from airborne surveys and laboratory measurements. The geostatistical method Collocated CoKriging is used for the spatial interpolation of the sparse gamma ray data, adopting a high-resolution geological map as ancillary information. The obtained numerical map is integrated with the cosmic radiation effective dose rate calculated using the CARI-7 software tool that considers the effects of altitude, latitude, and the solar magnetic activity cycle. The absorbed dose rate due to radioactivity of the main lithological groups is studied and, for the most populated municipalities, the population-weighted average effective dose is also calculated. For future generations, this map will be a reference tool for evaluating radiological effects in case of accidental events like radioactive fallout or environmental contaminations.

description: In diesem Beitrag werden die Auswirkungen eines Wegfalls von festen Klassenstrukturen an der Universitätsschule Dresden auf die Sozialkontakte der Schüler*innen untersucht. Im Mittelpunkt steht dabei die Annahme, dass der Wegfall fester Klassenverbände einerseits zu einer Vergrößerung des Interaktionsraums und damit der potenziellen Anzahl möglicher Sozialkontakte führt, dass der Wegfall der Opportunitätsstruktur Klassenverband andererseits jedoch auch Erwartungssicherheiten senken kann, was die Anzahl und die Qualität von Sozialkontakten verringern würde. Um dies zu untersuchen, wurden alle ca. 200 Schüler*innen des ersten Jahres der Universitätsschule nach ihren Sozialkontakten befragt, und die sich daraus ergebende Netzwerkstruktur wurde mit entsprechenden Strukturen an vergleichbaren „regulären“ Schulen verglichen. Dabei ergaben sich für die Universitätsschule dichtere und verästeltere Strukturen von Kontakten vergleichbarer Stabilität und höherer Reziprozität. Die Anzahl relativ wenig integrierter Schüler*innen war an der Universitätsschule etwas niedriger als beim Durchschnitt der Vergleichsschulen.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The study had looked at the potential of the country regarding deposit mobilization by taking CBE as an evidence. The study had used both primary and secondary data. The primary data is collected by a means of interview and questionnaire. The secondary data for the study were the values of dependent and independent variables. The study had found variables that can affect the total deposit of commercial banks. Three variables are regressed with the dependent variable, i.e. total deposit, these variables include deposit rate, inflation rate and bank branches. The data for these variables was collected from commercial bank of Ethiopia, national bank of Ethiopia and central statistics authority of the sample year from 2000GC up to 2011GC. The multiple regression model is constructed for the dependent variable and the three independent variables. Different diagnostic tests are tested to know whether the model is valid or not, having the model is valid the regression analysis and hypothesis testing is performed using EViews software. As a result of the hypothesis testing it was found that all the three variables can affect total deposit. Branch expansion had positive and significant effect on total deposit whereas deposit rate and inflation rate had positive and insignificant effect on total deposit. Finally the study had recommend what should be done to mobilize more deposits.
Determining the Optimum Parameters of an Energy harvesting System using Simulation
Creators: name: Akello, Fiona
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Ethiopia has a small percentage of its population accessing electricity with some energy utilized by the transportation sector, also there are frequent power outages at the Addis Ababa Light Rail Transit Services which takes a long while to return. From this former statement, it is clear that demand for energy is high and there is too much dependability on the current energy source. The aim of this study is to simulate an energy harvesting system using vibration from the track using a two degree of freedom oscillator. Secondary data was collected, then a damped Mass-spring-two degree of freedom oscillator was modeled and the energy harvested from the system simulated. This oscillator produces mechanical energy to power signaling and communication equipment of the railway line. The optimum parameters of the energy harvester were determined; the mass of 1 kg, a spring stiffness of 0.12 N/m and a damping coefficient of 5.5Ns/m. The cumulative mechanical power harvested by Addis Ababa Light Rail Transit's lowest speed was calculated to be 8.06 ��. The damped two-degree-of-freedom oscillator produces higher mechanical energy, therefore meeting the energy demand of the signaling and communication equipment.

description: Background: We previously found a conditioned increase in central neuroinflammatory markers (Interleukin 6; IL-6) following exposure to alcohol-associated cues. Recent studies suggest (unconditioned) induction of IL-6 is entirely dependent on ethanol-induced corticosterone. Objectives: The goals of these present studies were to test whether alcohol-paired cues facilitated the hypothalamic-pituitary-adrenal (HPA) axis response to either a subthreshold priming alcohol dose or an immune or psychological stress challenge Methods: In Experiment 1 (N = 64), adult male Sprague Dawley rats were trained (paired or unpaired, four pairings total) with either vehicle or 2 g/kg alcohol [intragastric (i.g.) or intraperitoneal (i.p.)] injections. In Experiments 2 (N = 28) and 3 (N = 30), male rats were similarly trained but with 4 g/kg alcohol i.g. intubations. On test day, all rats were either administered a 0.5 g/kg alcohol dose (i.p. or i.g. Experiment 1), a 100 µg/kg i.p. lipopolysaccharide (LPS) challenge (Experiment 2), or a restraint challenge (Experiment 3), and exposed to alcohol-associated cues. Blood plasma was collected for analysis. Results: Alcohol-associated cues facilitated the plasma corticosterone response to a subthreshold dose of alcohol (F1,28 = 4.85, p < .05) and an immune challenge (F8,80 = 6.23, p < .001), but not a restraint challenge (F2,27 = 0.18, p > .05). Conclusion: These findings reveal that the impact of the cues associated with alcohol intoxication on the HPA axis may be context-specific. This work illustrates how HPA axis learning processes form in the early stages of alcohol use and has important implications for how the HPA and neuroimmune conditioning may develop in alcohol use disorder in humans and facilitate the response to a later immune challenge.

description: The objective of this study was to analyze the inventory management practices in the organization in order to identify the inventory management challenges and its contributing factors for challenges and recommend solutions for improvement. It was carried out using case study at Sur Construction Company. In this organization, stocks outs, rush ordering, unplanned and urgent purchasing items observed frequently while high non-moving and obsolescence was available as a problem. In this research sample of 120 employees was in used by purposive sampling technique and the return rate was 98 which is 82% response rate. Questionnaires, interviews, and secondary data from reports and internet was used as data collection instrument, analyzed by Microsoft excel software applying descriptive statistics. According to these data, the overall inventory practice was not effective; and the major inventory management challenge was the availability of item on time in complete set. The finding shows that the main contributing factor for this problem was staff capacity having skill gap and awareness in implementing inventory management technique. Accordingly, staff development and capacity enhancement strategy including training, empowerment and motivation scheme design was recommended.

description: Slope units represent surface slopes by means of polygons delimited by drainage and divide lines obtained on a digital topography. Objective slope unit delineation for a given digital elevation model is still an open issue and, often, a limitation that may dictate the use of a more traditional pixel-based approach for spatial analysis. Availability of slope unit maps facilitates many kinds of studies and allows scholars to focus on specific scientific issues rather than on preparing sound mapping units from scratch for their research. Here, we present a slope unit map of a large portion of the Himalayas. The map is prepared following a widely tested, parameter-free optimization algorithm. The area encompassed by the map is relevant to studies of the well-known 2015 Gorkha earthquake and monsoons, which makes it relevant to a vast portion of the scientific community working in natural hazards including, but not limited to, landslide scientists and practitioners. The map contains 112,674 polygons with average area of 0.38 km2 and is published in vector form. The map is accompanied by a selection of data including morphometric and thematic quantities. In addition to describing the rationale behind the delineation of the polygonal map and selected data, we describe an application devoted to unsupervised terrain classification. We applied a k-means clustering procedure with two strategies: one at (coarser) basin scale and one at (finer) slope unit scale. We show similarities and differences between the two classification strategies, highlighting the role of the slope unit subdivision in the two cases.

description: Recently there have been experimental results on Poisson spot matter wave interferometry followed by theoretical models describing the relative importance of the wave and particle behaviors for the phenomenon. We propose an analytical theoretical model for the Poisson's spot with matter waves based on Babinet principle in which we use the results for a free propagation and single slit diffraction. We take into account effects of loss of coherence and finite detection area using the propagator for a quantum particle interacting with an environment. We observe that the matter wave Gouy phase plays a role in the existence of the central peak and thus corroborates the predominantly wavelike character of the Poisson's spot. Our model shows remarkable agreement with the experimental data for deuterium ($D_{2}$) molecules.

description: We consider a general class of four-dimensional geometries admitting a null vector field that has no twist and no shear but has an arbitrary expansion. We explicitly present the Petrov classification of such Robinson-Trautman (and Kundt) gravitational fields, based on the algebraic properties of the Weyl tensor. In particular, we determine all algebraically special subcases when the optically privileged null vector field is a multiple principal null direction (PND), as well as all the cases when it remains a single PND. No field equations are a priori applied, so that our classification scheme can be used in any metric theory of gravity in four dimensions. In the classic Einstein theory this reproduces previous results for vacuum spacetimes, possibly with a cosmological constant, pure radiation and electromagnetic field, but can be applied to an arbitrary matter content. As non-trivial explicit examples we investigate specific algebraic properties of the Robinson-Trautman spacetimes with a free scalar field, and also black hole spacetimes in the pure Einstein-Weyl gravity.

description: We used combined data from XMM-Newton and Chandra observatories to study the X-ray morphology of SNR G306.3-0.9. A spatially-resolved spectral analysis was used to obtain physical and geometrical parameters of different regions of the remnant. Spitzer infrared observations were also used to constrain the progenitor supernova and study the environment in which the SNR evolved. The X-ray morphology of the remnant displays a non-uniform structure of semi-circular appearance, with a bright southwest region and very weak or almost negligible X-ray emission in its northern part. These results indicate that the remnant is propagating in a non-uniform environment as the shock fronts are encountering a high-density medium, where enhanced infrared emission is detected. The X-ray spectral analysis of the selected regions shows distinct emission-line features of several metal elements, confirming the thermal origin of the emission. The X-ray spectra are well represented by a combination of two absorbed thermal plasma models: one in equilibrium ionization with a mean temperature of ~0.19 keV, and another out of equilibrium ionization at a higher temperature of ~1.1 or 1.6-1.9 keV. For regions located in the northeast, central, and southwest part of the SNR, we found elevated abundances of Si, S, Ar, Ca, and Fe, typical of ejecta material. The outer regions located northwest and south show values of the abundances above solar but lower than to those found in the central regions. This suggests that the composition of the emitting outer parts of the SNR is a combination of ejecta and shocked material of the interstellar medium. The comparison between the S/Si, Ar/Si, and Ca/Si abundances ratios (1.75, 1.27, and 2.72 in the central region, respectively), favor a Type Ia progenitor for this SNR, a result that is also supported by an independent morphological analysis using X-ray and IR data.

description: Eurasian red squirrels Sciurus vulgaris have unusually high δ13C values compared to other forest rodents, which is seemingly related to the consumption of 13C-enriched conifer seeds. To test this hypothesis, we analyzed the hair of wild and zoo-kept red squirrels, seeds of pine and spruce, and feathers of specialized and opportunistic consumers of conifer seeds, crossbills Loxia spp., and woodpeckers Dendrocopos major. Data on the isotopic composition (δ13C and δ15N values) of hair or feathers of other species of forest rodents and birds were obtained from published studies. The range of mean δ13C values of hair of wild forest rodents (19 species) exceeded 10 ‰. All squirrel species had high 13C content, S. vulgaris having maximum δ13C values. In contrast, S. vulgaris kept in captivity had an isotopic composition similar to other captive rodents. The feathers of crossbills were enriched in 13C compared to other forest birds (15 species), while seeds of coniferous trees often had higher δ13C values compared to seeds of other woody plants. Distinctiveness of the isotopic composition of mammals and birds feeding on the seeds of coniferous trees suggests that this resource can be traced through the entire forest food web.
