Feeding ecology of short-tailed shearwaters: breeding in Tasmania and foraging in the Antarctic?

The food, feedlng and physiological ecology of foraging were studied in the short-tailed shearwater Puffinus tenujrostris of Tasmania, to establish whether this species can rely on Antarctic food to fledge its chick. Parents were found to use a 2-fold foraging strategy, on average performing 2 successive short trips at sea of 1 to 2 d duration followed by 1 long trip of 9 to 17 d. These long foraging tnps are the longest yet recorded for any seabird. During short trips the parents tend to lose mass, feeding the chick with Australian krill and fish larvae caught in coastal and neritic waters around Tasmania. The prey are caught at maximum diving depths of 13 m on average (maximum 30 m). During long trips, adults gain mass and feed their chlcks with a very rich mixture of stomach oil and digested food composed of a high diversity of prey including myctophid fish, sub-Antarctic krill and squids. Prey are probably caught mainly in the Polar Frontal Zone, at least 1000 km south of Tasmania, at maximum depths of 58 m on average (maximum 71 m). Long foraging trips in distant southern waters gave at least twice the yield of trips in close waters but during the former, yield decreased with the time spent foraging, as indicated by the inverse relationship between time spent forag~ng and adult body condition. Decisions whether to forage in close or distant waters appear to be determined by the body condition of :he paieiits iclthei i i ~ a ~ ~ by ihdi oi ihe C ~ ~ C K . Good body condition of parents was associated with high blood prolactin levels: birds in poor body condition invested in the restoration of body reserves and went to the rich area of the Polar Frontal Zone or to Antarctic waters, whereas those in good condition continued to provision the chick with food caught in Tasmanian waters and use their body reserves. The species thus exploits 2 water masses that differ in profitability. Most of the energy budget for rearing the ch~ck 1s balanced by prey caught in rich southern waters where the birds build up their body reserves and find most of the energy needed by the chick. However, nearby shallow waters are important for the breeding strategy as they allow an increased rate of energy flow to the chick. In a species as abundant as the short-tailed shearwater, the 2-fold strategy has the advantage of limiting competition in coastal and shallow waters, as at any one time only 17 % of birds are feeding there. The influence of the manne environment and energetic constra~nts on the evolution of provisioning strategies is discussed.
New Teff and [Fe/H] spectroscopic calibration for FGK dwarfs and GK giants

Context. The ever-growing number of large spectroscopic survey programs has increased the importance of fast and reliable methods with which to determine precise stellar parameters. Some of these methods are highly dependent on correct spectroscopic calibrations. Aims. The goal of this work is to obtain a new spectroscopic calibration for a fast estimate of Te and [Fe/H] for a wide range of stellar spectral types. Methods. We used spectra from a joint sample of 708 stars, compiled from 451 FGK dwarfs and 257 GK-giant stars. We used homogeneously determined spectroscopic stellar parameters to derive temperature calibrations using a set of selected EW line-ratios, and [Fe/H] calibrations using a set of selected Fei lines. Results. We have derived 322 EW line-ratios and 100 Fei lines that can be used to compute Te and [Fe/H], respectively. We show that these calibrations are e ective for FGK dwarfs and GK-giant stars in the following ranges: 4500 K < Te < 6500 K, 2:5 < logg < 4:9 dex, and 0:8 < [Fe=H] < 0:5 dex. The new calibration has a standard deviation of 74 K for Te and 0:07 dex for [Fe/H]. We use four independent samples of stars to test and verify the new calibration, a sample of 56 giant stars, a sample composed of Gaia FGK benchmark stars, a sample of 36 GK-giant stars of the DR1 of the Gaia-ESO survey, and a sample of 582 FGK-dwarf stars. We also provide a new computer code, GeTCal, for automatically producing new calibration files based on any new sample of stars.
Saharan Africa : An essential first step in adapting to future climate change ?

Rain-fed agriculture will remain the dominant source of staple food production and the livelihood foundation of the majority of the rural poor in sub-Saharan Africa (SSA). Greatly enhanced investment in agriculture by a broad range of stakeholders will be required if this sector is to meet the food security requirements of tomorrow’s Africa. However, production uncertainty associated with between and within season rainfall variability remains a fundamental constraint to many investors who often over estimate the negative impacts of climate induced uncertainty. Climate change is likely to make matters worse with increases in rainfall variability being predicted. The ability of agricultural communities and agricultural stakeholders in SSA to cope better with the constraints and opportunities of current climate variability must first be enhanced for them to be able to adapt to climate change and the predicted future increase in climate variability. Tools and approaches are now available that allow for a better understanding, characterization and mapping of the agricultural implications of climate variability and the development of climate risk management strategies specifically tailored to stakeholders needs. Application of these tools allows the development and dissemination of targeted investment innovations that have a high probability of biophysical and economic success in the context of climate variability. # 2008 Elsevier B.V.

Absolute densities in exoplanetary systems: photodynamical modelling of Kepler-138

In favourable conditions, the density of transiting planets in multiple systems can be determined from photometry data alone. Dynamical information can be extracted from light curves, providing modelling is done self-consistently, i.e. using a photodynamical model, which simulates the individual photometric observations instead of the more generally used transit times. We apply this methodology to the Kepler-138 planetary system. The derived planetary bulk densities are a factor of 2 more precise than previous determinations, and we find a discrepancy in the stellar bulk density with respect to a previous study. This leads, in turn, to a discrepancy in the determination of masses and radii of the star and the planets. In particular, we find that interior planet, Kepler-138b, has a size in between Mars and the Earth. Given our mass and density estimates, we characterize the planetary interiors using a generalized Bayesian inference model. This model allows us to quantify for interior degeneracy and calculate confidence regions of interior parameters such as thicknesses of the core, the mantle, and ocean and gas layers. We find that Kepler-138b and Kepler-138 d have significantly thick volatile layers and that the gas layer of Kepler-138b is likely enriched. On the other hand, Kepler-138c can be purely rocky.
Survey on Multi Agent Energy Efficient Clustering Algorithms in Wireless Sensor Networks

In the last few years, there are many applications for Wireless Sensor Networks (WSNs). One of the main drawbacks of these networks is the limited battery power of sensor nodes. There are many cases to reduce energy consumption in WSNs. One of them is clustering. Sensor nodes partitioned into the clusters so that one is chosen as Cluster Head (CH). Clustering and selection of the proper node as CH is very significant in reducing energy consumption and increasing network lifetime. In this paper, we have surveyed a multi agent clustering algorithms and compared on various parameters like cluster size, cluster count, clusters equality, parameters used in CHs selection, algorithm complexity, types of algorithm used in clustering, nodes location awareness, inter-cluster and intra-cluster topologies, nodes homogeneity and MAC layer communications.
A rationale for implicit turbulence modelling

We present a rationale for the success of nonoscillatory finite volume (NFV) difference schemes in modelling turbulent flows without need of subgrid scale models. Our exposition focuses on certain truncation terms that appear in the modified equation of one particular NFV scheme, MPDATA. We demonstrate that these truncation terms have physical justification, representing the modifications to the governing equations that arise when one considers the motion of finite volumes of fluid over finite intervals of time.

Non-Hodgkin Lymphoma Presented with Peritoneal Seeding: A Case Report

Lymphoma is the most common malignancy originating from hematopoietic systems. Diverse biological and clinical manifestations of non-Hodgkin lymphoma have been recognized. As an unusual type of non-Hodgkin lymphoma is Burkitt lymphoma. The variability of the initial presentation is not unusual. We present a 15-year-old boy with generalized abdominal pain, fever. He had massive orange pleural effusion and ascites. There were peritoneal seeding and omentum thickening in abdominal computed tomography scan. Pathological investigations of the peritoneal biopsy revealed B-cell lymphoma (starry sky in pathology). The clinical presentation of sporadic Burkitt lymphoma could mimic some other diseases. Therefore, the clinicians should consider Burkitt lymphoma between the multiple differential diagnoses. In the case of peritoneal involvement, its differential diagnosis could be usually, peritoneal carcinomatosis, malignant peritoneal mesothelioma, and tuberculous peritonitis.
The disruption of proteostasis in neurodegenerative disorders

Cells count on surveillance systems to monitor and protect the cellular proteome which, besides being highly heterogeneous, is constantly being challenged by intrinsic and environmental factors. In this context, the proteostasis network (PN) is essential to achieve a stable and functional proteome. Disruption of the PN is associated with aging and can lead to and/or potentiate the occurrence of many neurodegenerative diseases (ND). This not only emphasizes the importance of the PN in health span and aging but also how its modulation can be a potential target for intervention and treatment of human diseases.
New parametrization for spherically symmetric black holes in metric theories of gravity

We propose a new parametric framework to describe in generic metric theories of gravity the spacetime of spherically symmetric and slowly rotating black holes. In contrast to similar approaches proposed so far, we do not use a Taylor expansion in powers of M / r , where M and r are the mass of the black hole and a generic radial coordinate, respectively. Rather, we use a continued-fraction expansion in terms of a compactified radial coordinate. This choice leads to superior convergence properties and allows us to approximate a number of known metric theories with a much smaller set of coefficients. The measure of these coefficients via observations of near-horizon processes can be used to effectively constrain and compare arbitrary metric theories of gravity. Although our attention is here focussed on spherically symmetric black holes, we also discuss how our approach could be extended to rotating black holes.
THE RELATIONSHIP BETWEEN RISK-ADJUSTED PERFOR- MANCE OF ACTIVELY MANAGED MUTUAL FUNDS INVESTING IN EUROPEAN EQUITIES AND MACROECONOMIC FEAR FAC- TORS

I find a significant relationship between a current level of some well-known macroeconomic fear factors which measure the prevailing economic or investor sentiment and subsequent equity mutual fund performance and stock market returns in European markets. When the level of macroeconomic fear in the beginning of a three or five-year measurement period is relatively high, the future stock market returns and mutual fund performance is expected to be relatively higher as well and vice versa. However, the results depend on a given macroeconomic fear factor, serial correlation adjustment procedure, time period and a risk-adjustment method with respect to mutual fund performance. This finding supports and complements previous results regarding the time-varying nature of mutual fund alpha presented for example by Kosowski (2011). This study also contributes to understanding how the new multi-factor composite sentiment indexes developed by Baker and Wurgler (2006) and Huang, Jiang, Tu and Zhou (2015) are linked to future equity mutual fund performance in Europe.
The Writing Centre: a site for discursive dialogue in Management studies.

This article contributes to the ongoing conversation, in the South African Journal of Higher Education (SAJHE) and other journals, about academic literacy development in higher education. It reports on a small-scale quantitative study on the effect of writing centre support on students' academic performance, in the disciplinary context of management studies. The study generated questions and areas for reflection about how to assess the ways in which writing centres can become more valuable programmatically, institutionally, theoretically and methodologically. Its uniqueness arises from the attempt to look at the development of academic literacy writing competences not during the transition from school to university, but at the exit point of an academic bachelor's degree programme. It raises questions, such as: Is there a value for academic discourse induction even at this exit stage, and what impact does it have on the development of writing competences? How does this impact become known?
Switched-Current Techniques: An Overview of Cumulative SI-Related Errors on Dynamic and Static Performances of 2 nd Order LP-∑ΔMs

We present in this work a systematic analysis to identify Sigma Delta Modulators (∑ΔMs) non-idealities, such as charge injection error, Input/Output conductance ratio error and settling time error. A physical mechanism behind Switched Current (SI) errors is proposed. In the first time, errors mentioned above are treated separately and a behavioural model of SI cell is derived for each non-ideality. In the second time, we propose a behavioural model of Non-inverting Lossless Integrator. For typical variations of SI-related errors, simulations have been made using Matlab/Simulink. Finally we present their influences on both dynamic and static performances of the 2nd order SI Low Pass ∑ΔMs (SI-LP∑ΔMs).
A Theory of Immigration Amnesties

This paper presents a first attempt at understanding some of the many issues involved in the granting of an amnesty to illegal immigrants. We consider government behavior with respect to allocations on limiting infiltration (border control) and apprehending infiltrators (internal control) and with respect to the granting of amnesties, the timing of amnesties, and limitations on eligibility for those amnesties. We demonstrate the effects of government actions on allocations and the flow of immigrants, and how the interactions between these factors combine to yield an optimal amnesty policy. We also consider various extensions such as intertemporal transfers of policing funds, risk-aversion, and "fuzziness" in declarations regarding eligibility for an amnesty aimed at apprehending and deporting undesirables.
A Conceptual Approach To Economic Agglomerations

Technological progress and rapid structural adjustments have characterized a lot of economies in the last century and they still feature pronounced structures. An important observation is that economic activities tend to agglomerate in space as a result of some kind increasing returns, forming eventually economic agglomerations. When various companies gather together, they establish specific forms of interaction. Increasing returns produce when this mutual interplay creates positive externalities for those firms which operate into an agglomeration. In this context, it is crucial to raise a question: what is an economic agglomeration and what do different scientists imply when using the concept? The phenomenon of agglomeration has attracted researchers from various disciplines employing a hybrid set of analytical perspectives. This whole framework is still puzzled with contradictory conceptualizations which are often used in an ambiguous way. Scientists tend to utilize notions such as agglomeration, cluster, territorial network, specialization, concentration somewhat interchangeably and with little concern about how to operationalize them. To shed a light on this issue, the aim of this paper is to provide a comprehensive analyze of different theoretical framework in which economic agglomerations have been debated and researched.
An Improved Procedure for the Enrichment of Plasma F2-Isoprostanes Prior to Final Determination by GC-MS/NICI

One of the most popular approaches to quantify oxidative injury is to measure lipid peroxidation products and, in particular, F2-isoprostanes (F2-IPs). F2-IPs is a group of prostaglandin F2-like compounds derived from the non-enzymatic oxidation of arachidonic acid. Of these, the 15-F2t-isoprostane (8-iso-PGF2 ) has received considerable attention, because it possesses adverse biological activities. Previous Gas Chromatographic-Mass Spectrometric (GC-MS) methods for measuring plasma F2-IPs from this laboratory involved two chromatography steps on C18 and NH2-cartridges. Problems may, however, arise with chromatography on C18 cartridges, as it can be time-consuming and losses may occur depending upon the pH and e ciency of the sample loading. Therefore, it was decided that the C18 chromatography step be replaced with a single lipid partitioning step and the NH2-chromatography be simpli ed. In 70 plasma samples from healthy individuals, total (sum of free and esteri ed) 15-F2t-isoprostane concentrations ranged from 0.5 to 3.13 nM. This assay meets all prede ned method performances in terms of speci city and sensitivity. The improved method is suitable for the analysis of samples from larger clinical trials investigating the role of oxidant injury under conditions associated with oxidative stress.
Enhancing Internal Customer Satisfaction Through Organizational Development Intervention: A Case Study

This action research identifies and investigates the impact of organizational development intervention (ODI) on enhancing internal customer satisfaction. The two foci of satisfaction in this study were organizational communication and information/knowledge sharing. AB, an in-house tour production unit of an Airline, was used as a case study. The ODI was designed and implemented by using a knowledge management project through the creation of the selling office’s community website which acts as a virtual community for selling offices to strengthen and improve organizational communication and information/knowledge sharing. The informants consisted of representatives from AB’s fifty-five selling offices worldwide. Both quantitative and qualitative approaches using questionnaires, interviews and observations were used to collect and analyze data. After the ODI, it was revealed that the satisfaction of selling offices, as internal customers, with both organizational communication and information/knowledge sharing was increased. Strong positive relationships between internal customer satisfaction with organizational communication and internal customer satisfaction with information/knowledge sharing, including the moderate to strong relationships among all dimensions were discovered. In addition, a strong positive relationship between the number of website visits and packages sold was also revealed.
EVALUATION OF THE NUTRITIONAL POTENTIAL OF Ceiba pentandra LEAVES

Ceiba pentandra is a tropical tree of the order Malvales and of the family Malvaceae which was previously separated from the family Bombacaceae. Its leaf has been found to possess many medicinal and nutritional properties. Ceiba Pentandra is huge, wide and normally found in the wild forest of West Africa in the tropical forest regions. This work was carried out to investigate the potential nutritional values of Ceiba pentandra leaf with a view to evaluating the nutritional importance of the plant. This was achieved by evaluating the proximate, quantitative phytochemicals and vitamin constituents of the plant. The result of the proximate analysis revealed relatively high percentage of moisture (47.37%), protein (16.81%), carbohydrate (25.23%), low percentage of fibre (4.47%), fats (2.23%) and ash (2.14%). Results of the quantitative phytochemical analysis revealed alkaloids (4.887±0.07), terpenoids (0.934±0.011), flavonoids (20.147±0.651), polyphenol (99.34±0.753) and saponin (3.91±0.119). Also, the result of the vitamin composition showed the presence of vitamin A (2.323μg/g), vitamin C (0.6863mg/100g) and vitamin E (1.8836mg/100g). In the light of this investigation, Ceiba pentandra has been found to contain some nutrients and this supports its ethno-medicinal uses and therefore makes it a good source of nutrients and medicine that require special attention for development. Keywords: Ceiba pentandra, Nutrients, Proximate analysis, Vitamins and Malvales.
An implementation of the argument dependency model

Human sentence processing proceeds in a left-to-right incremental manner and is able to assign partial structural interpretations even if all the lexical items involved are not yet known. To mimic such a behaviour in a computational system is particularly difficult for head final languages where the rich information about the valency of the verb comes last. In such cases the Argument Dependency Model facilitates early hypotheses about the thematic status of a constituent by establishing direct argument-to-argument dependencies independent of the verb. An implementation of the model within the framework of Weighted Constraint Dependency Grammar is presented and evalated in a pseudo-incremental processing mode. Thanks to its non-monotonic nature the system can replicate the predictions of the Argument Dependency Model about the dynamic nature of revision processes during sentence comprehension with a very high degree of reliability. Menschliche Sprachverarbeitung erfolgt inkrementell von links nach rechts und ist in der Lage, partielle Strukturhypothesen aufzustellen, auch wenn die beteiligten lexikalischen Elemente erst teilweise bekannt sind. Die maschinelle Nachbildung eines solchen Verhaltens ist besonders problematisch fuer kopffinale Sprachen, in denen die reichhaltige Valenzinformation des Verbs erst sehr spaet verfuegbar ist. In solchen Faellen gestattet das Argument Dependency Model fruehzeitige Hypothesen ueber die thematischen Rollen einer Konstituente, indem es unabhaengig vom Verb, direkte Abhaengigkeitsbeziehungen zwischen seinen Argumenten aufbaut. Der Bericht stellt eine Implementation des Modells im Rahmen der Weighted Constraint Dependency Grammar vor und evaluiert diese in einem pseudo-inkrementellen Verarbeitungsmodus. Dank seiner nichtmonotonen Verarbeitungsweise kann das System die Vorhersagen des Argument Dependency Model ueber die dynamischen Revisionsprozesse beim Sprachverstehen mit einem sehr hohen Grad an Genauigkeit replizieren.
Portal MOM – Morar de outras maneiras: inconsistências em design de interface

Academic departmental sites, research groups, and other university programs, for the most part, point to significant flaws in the human-computer interaction relationship. The article aims to identify and expose the inconsistencies present in the virtual page of the research group called MOM Living in other ways, hosted by the Department of Projects (PRJ) and the Postgraduate Program in Architecture and Urbanism (NPGAU) of Architecture of UFMG. From the empirical method Verbal Protocol conducted with users students and researchers in the area of Architecture, it was possible to verify the real difficulties of usability with the site chosen as object of study.
