On an alternative to Wong’s asymptotic expansion of the
Kontorovich–Lebedev transform near the origin
Authors: Naylor Derek 
Published: February 2019

Abstract
An asymptotic expansion is constructed for values near the origin of a
function whose Kontorovich–Lebedev transform is an even analytic function.
The expansion obtained is expressed in terms of the poles and residues of
the analytic function and provides an alternative to one obtained by Wong
(1981) which becomes inapplicable.
Composite Finite Element Approximation for Parabolic Problems in Nonconvex Polygonal Domains
Authors: Pramanick Tamal , Sinha Rajen Kumar 
Published: February 2019

Abstract
The purpose of this paper is to generalize known a priori error estimates of the composite finite element (CFE) approximations of elliptic problems in nonconvex polygonal domains to the time dependent parabolic problems. This is a new class of finite elements which was introduced by [W. Hackbusch and S. A. Sauter,
Composite finite elements for the approximation of PDEs on domains with complicated micro-structures,
Numer. Math. 75 1997, 4, 447–472] and subsequently modified by [M. Rech, S. A. Sauter and A. Smolianski,
Two-scale composite finite element method for Dirichlet problems on complicated domains,
Numer. Math. 102 2006, 4, 681–708] for the approximations of stationery problems on complicated domains. The basic idea of the CFE procedure is to work with fewer degrees of freedom by allowing finite element mesh to resolve the domain boundaries and to preserve the asymptotic order convergence on coarse-scale mesh. We analyze both semidiscrete and fully discrete CFE methods for parabolic problems in two-dimensional nonconvex polygonal domains and derive error estimates of order

Breeding population of Peregrine Falcon (Falco peregrinus) in Lazio, Central Italy: 1983–2017
Authors: Brunelli Massimo , Sarrocco Stefano 
Published: February 2019

Abstract
In 1983–1984 the nesting population of Peregrine Falcon (Falco peregrinus) in Lazio was estimated to 25–30 pairs located mainly in the limestone massifs of the Southern Anti-Apennines and the Ponziane Islands. The monitoring carried out in the following years showed a steady increase in population size and range. In 2014–2017, the breeding population was 166–193 pairs distributed over most of the regional territory. In four regional macro-geographic areas characterized by different morphologies, lithological and landscape typologies, the density was calculated by NND method, which varied from a minimum of 0.90 to a maximum of 1.77 pairs/100 km2; average distance between sites from 3848.18 m to 6526.87 m. The urban population of Rome increased from the first nest found in 2001 to 15 currently breeding pairs; the first artificial nest was discovered in 2001 on the building, currently 14 are known. At present in Lazio 16 nests are located in quarries. In the years 2008, 2014, 2015 and 2016, the fledging rate registered was 2.26 (SD = 0.94; bp = 153).

Published: February 2019

Abstract
Since the 1980s, the volunteers of the ornithological group of the Nature Midi-Pyrénées association have been monitoring the Peregrine Falcon (Falco peregrinus) population in the Ariège Pyrenees and in the Toulouse agglomeration. The data collected over the last 30 years show stability of the Ariège population: little variation has been observed in brood size, occupation rate of the sites or reproductive success. Only the increasing number of known nesting sites is significant, due to better knowledge of the territory by observers over time. In 2017, the breeding population was estimated to be 24 pairs. Urban monitoring proved the presence of individuals in passage, wintering or resident in Toulouse. Since 2002, downtown Toulouse has been visited by several individuals of both sexes and interactions between males and females have been observed since 2005. Despite the multiplicity of possible eyries or nesting sites in Toulouse, and the massive presence of Peregrine Falcons and dedicated bird watchers, no case of breeding has been reported. In addition to monitoring, measures to protect and support the presence of the species have been put in place. In the Pyrenees, in the light of the growth of human activities near nesting sites, some sites are now subject to official protective measures, coupled with constant vigilance and awareness. In Toulouse, to encourage the breeding of the individuals present, two nesting boxes were installed in 2016, on two buildings frequented by a female and a male. In 2017, a first attempt to reproduce in one of these installations confirmed the value of such developments in urban areas.
Extreme territorial aggression by urban Peregrine Falcons toward Common Buzzards in South-West England
Authors: Dixon Nick , Gibbs Andrew 
Published: February 2019

Abstract
Peregrine Falcons (Falco peregrinus) breeding on a city centre church in Exeter, in the south-west of England, have been studied in detail since first occupation in 1997. During this period, changes in both male and female falcons have been recorded. Following the arrival of a new female Peregrine in 2009, a dramatic change in behaviour towards Common Buzzards (Buteo buteo) on passage over the city was noted. Buzzards flying over Exeter are attacked by the falcons, especially so when in proximity to the church. We have attempted to document these attacks through our own observations, with additional information from local residents and wildlife organisations. Further records have come from veterinary surgeries and wildlife rehabilitators regarding injured buzzards found in the city. This paper documents the extreme levels of territorial aggression as demonstrated by the pair of Peregrines during cooperative attacks on Buzzards. We reveal this unique interspecific behaviour by summarising the number, frequency, timing and outcome of attacks undertaken over an eight-year period. We describe and illustrate the strategy employed by the Peregrines during a typical attack, plus consider implications on breeding productivity and the future scenarios should one of the current pair be replaced.
Enhanced Thermal and Mechanical Properties of Polymer Reinforced with Slightly Functionalized Graphene Nanoplatelets

Published: February 2019

Abstract
Slightly oxidized graphene nanoplatelets (GNPs) were functionalized using 3-hydroxytyramine hydrobromide. The functionalized GNPs, denoted as fGNPs, were examined using Fourier transform infrared and a Raman spectrometer, which revealed a slight reduction in the sp2 network domain compared with unmodified GNPs. Compared with previous reports on functionalized highly oxidized graphene, the degree of the sp2 structural destruction was less, as revealed by Raman analysis. The aim was to address the challenges of high agglomeration of graphene in polymer matrix and high destruction of graphene’s conjugal structure during functionalization, which deteriorates graphene’s excellent properties and makes it less effective in improving the polymer’s properties. This was achieved by slight functionalization of GNPs because they contained little oxygen functional groups. In this study, a thermal conductivity increase of about 295 % was recorded when 6.67 wt. % fGNPs were incorporated into the poly(vinylidene fluoride) (PVDF) matrix. Also, with 3.34 wt. % of the GNPs composite, the tensile strength and Young’s modulus were measured with an increase of about 64 % and 100 %, respectively. The enhanced properties of the polymer nanocomposites were due to better dispersion of fGNPs and interaction with the polymer matrix compared to unfunctionalized GNPs composites as was indicated by a scanning electron microscope. The composites were prepared by solution blending and melt compounding process. Such composites can find application in automobile and aerospace industries in which good mechanical and thermal properties are required.

Process Model for the Food Service in Swiss Hospitals
Authors: Weisshaupt Oliver , Leiblein-Züger Gabriela V. , Hofer Susanne 
Published: February 2019

ABSTRACT

Background
Since the introduction of Swiss Diagnosis Related Groups in 2012, a Swiss hospital's core business requires Facility Management that provides more transparent, effective and efficient services. In that respect, the new remuneration system has caused a growing interest in processes. Food provision is of high importance since it is one of the costliest support services and is a critical image factor of a hospital.

Purpose
The purpose of this research was to analyse the food service processes in Facility Management in hospitals through the lenses of social, economic and ecological sustainability as well as hygiene and safety, and to identify which issues arise from each viewpoint for the respective sub-processes.

Methodology
A two-fold qualitative case study design was applied, based on the reference model theory Process Model for Non-Medical Support Services in Hospitals. First, based on focus groups, the process model was developed. Second, the model was validated by input from interviews with Facility Management professionals.

Results
Each sub-process requires the consideration of individual factors from the perspectives of sustainability, hygiene and safety. Similarly, various overarching factors were identified, such as the production method that impact not only a single sub-process, but also play a role in the whole catering process. Additionally, it became evident that food provision in hospitals is particularly affected by the conflicting priorities of cost-effectiveness and sustainability.

Conclusion
The outcome of this work is a model that allows a holistic process analysis of catering activities in hospitals since it takes into account social, economic and ecological sustainability, as well as both hygiene and safety aspects for the individual sub-processes. This research gives guidance to facility managers who strive for process optimisation to guarantee efficient and effective food provision in hospitals.

Unique Value to the Body of Facility Management Knowledge
This work applies established catering sub-processes in hospitals to the context of sustainability, hygiene and safety. The proposed model caters to the increasing interest in processes in healthcare in Switzerland and can presumably be applied to hospitals of other countries.
GROWTH RATE COMPARISONS OF THREE COLOR MORPHS OF COMMON CARP (Cyprinus carpio L.) CULTURED IN COMMERCIAL FLOATING NET CAGES
Authors: Gustiano Rudhy 
Published: February 2019

The study aims at establishing possible relationships between growth of weight and color morphs difference of the common carp cultured in floating netcages. Ten floating net-cage (7 m × 7 m × 2 m) were selected from three farms in Cirata Reservoir for studying growth performance. Each cage-net was stocked with 300 kg of 12 cm–16 cm common carp juvenile. The fish was weighed every other week, i.e., at week 0, 2, 4, 6, and 8. The fish in each cage were gathered to one side of the cage with bamboo sheets. Thirty fish for each of three colors (blue, green, and red) were randomly sampled from each cage using a scoop net. The result showed that the green fish was the fastest growing in 2 of the 3 significant cases and blue for 1 case. In most cases color morphs also did not show any differences in the weight regression coefficients. However, there were 5 significant cases where green was always the best followed by the blue one. Thus, there was evidence that the dark color (green and blue) gained weight faster than light one (red). Green and blue colored showed similarity in growth performance based on weight regression coefficient.

Improvement of high yield maize cultivars possessing high quality of seed as showed by high lysine and tryptophan content must be fulfilled with resistance against downy mildew pathogen in any maize breeding program. A set of experiment to study genetic variability and to estimate both heritability and heterosis of important characters of grain yield on DMR and QPM lines has been conducted. Four downy mildew resistance (DMR) lines, i.e. Nei 9008, P 345, Ki 3, and MR 10; three quality protein maize (QPM) lines, including CML 161, CML 163, and CML 172; and their single cross hybrids formed based on line × tester mating design were used in the experiment. The following characters: height of the first ear, seeds number per row, seed weight per ear, and grain yield per plot showed broad genetic variability. Narrow sense heritability (hns) of grain yield and its components ranged from 0.01 to 0.71. Broad sense heritability (hbs), on the other hand, ranged from 0.20 to 0.74. It was found that hybrid derived from crossing between parental inbred lines possessing broad genetic background would express high heterosis.
Gene Transfer to Rice Mediated by Agrobacterium tumefaciens: Transient Expression of sgfp in Rice Calluses of indica cv. Fatmawati and japonica cv. Nipponbare
Authors: Yoshida Tomohiko , Carsono Nono 
Published: February 2019

Transient expression of synthetic green fluorescent protein (sgfp) mediated by Agrobacterium is rapid and useful approach for visual monitoring the genetic transformation event in transformed cells/tissues of examined genotype. The significant differences in transient expression of two genotypes (indica cv. Fatmawati and japonica cv. Nipponbare) were found with regard to the osmotic treatment (0.4 M mannitol), solid subcultured callus, and 10 min. air drying. While, no significant differences in sgfp expression were observed in two genotypes on without air-drying and 5 min. air-drying of calluses prior immersed in Agrobacterium suspension. Surprisingly, the sgfp expression could not be detected in suspension-subcultured callus of both cultivars. The highest sgfp expression was achieved in Nipponbare callus treated with 10 min. air drying. The level of green fluorescent spots was higher in Nipponbare than that in Fatmawati, however, plants regenerated from Fatmawati were considerably comparable with those of Nipponbare. Seventeen and 16 putative transgenic rice plants expressing sgfp transgene were obtained from Nipponbare and Fatmawati, respectively.

Performance Evaluation of Different Types of Shear Connectors in Steel–Concrete Composite Construction
Authors: Jayanthi V. , Umarani C. 
Published: February 2019

AbstractShear connectors are designed in steel-concrete composite construction to transmit the longitudinal shear, to prevent separation of steel and concrete slabs, and also to increase the structural efficiency of the whole system. In this study, the performances of different types of shear connectors in steel-concrete composite specimens are evaluated by conducting push-out tests under monotonic loading conditions. An ISMB 200 @ 25.4 kg/m universal steel beam measuring 400 mm and a reinforced cement concrete slab measuring 300 mm with a breadth of 200 mm and a thickness of 200 mm reinforced with 8 mm diameter steel rods are used for the experimental study. The results reveal that the load-slip relationships for various types of shear connectors and failure mechanisms are obtained to identify those shear connectors which are more relevant to the steel - concrete composite members.
Experimental Study of Low Cycle Fatigue Properties for Epoxy Resins with Dibutyl Phthalate (Dbp)
Authors: Wang Zhi , Zhou Jiajia , Song Linjian , Li Long 
Published: February 2019

AbstractIn order to improve the toughness of traditional epoxy resin, dibutyl phthalate (DBP) was introduced into the epoxy resin. The static mechanical performance of plasticized and unplasticized epoxy resin was evaluated. The test results showed that the DBP modified epoxy resin can obtain a higher toughness than conventional epoxy resin, but the elastic modulus and the tensile strength were slightly reduced. The low cycle fatigue test results indicated that the stress ratio and the stress level were two critical factors of fatigue life, which was increased with the growth of stress ratio. It was also found that the fatigue life of plasticized specimen was much less than that of the unplasticized specimen because of the plastic deformation. A logarithmic linear relationship was then established to predict the fatigue life for plasticized epoxy resin. The strain energy density was also applied to demonstrate the accumulation of energy loss. In addition, the fatigue toughness can be obtained by the hysteresis loop area method.
The Ecology of British Upland Landscapes. Ii. The Influence of Policy on The Current Character of The Uplands and The Potential for Change
Authors: Bunce Robert G.H. , Wood Claire M. , Smart Simon M. 
Published: February 2019

Abstract
The paper demonstrates that the British Uplands have been influenced to a great extent by policy - for example, the planting of almost a million hectares of exotic conifers since the Second World War, and the extent of designated areas. Otherwise, climate change transcends policy and is locally important to coastal and high mountain habitats. The different policies affecting the Uplands, such as the Common Agricultural Policy, are described, as are the wide range of designations such as National Parks, which may have a stabilising effect in times of great change. A new trend has started in Scotland in the last 20 years of local initiatives, such as the community ownership of Eigg, however large landowners still dominate. An impact table is presented of the habitats that make up the Uplands and their links to driving forces, with potential changes described that are likely to take place under future policies such as Brexit. Dwarf shrub heath is the habitat affected by many management drivers, whereas habitats such as Inland Rock, are relatively stable but most likely to be affected by climate change.
