Resistivity of non-Galilean-invariant Fermi- and non-Fermi liquids

While it is well-known that the electron-electron (\emph{ee}) interaction cannot affect the resistivity of a Galilean-invariant Fermi liquid (FL), the reverse statement is not necessarily true: the resistivity of a non-Galilean-invariant FL does not necessarily follow a T^2 behavior. The T^2 behavior is guaranteed only if Umklapp processes are allowed; however, if the Fermi surface (FS) is small or the electron-electron interaction is of a very long range, Umklapps are suppressed. In this case, a T^2 term can result only from a combined--but distinct from quantum-interference corrections-- effect of the electron-impurity and \emph{ee} interactions. Whether the T^2 term is present depends on 1) dimensionality (two dimensions (2D) vs three dimensions (3D)), 2) topology (simply- vs multiply-connected), and 3) shape (convex vs concave) of the FS. In particular, the T^2 term is absent for any quadratic (but not necessarily isotropic) spectrum both in 2D and 3D. The T^2 term is also absent for a convex and simply-connected but otherwise arbitrarily anisotropic FS in 2D. The origin of this nullification is approximate integrability of the electron motion on a 2D FS, where the energy and momentum conservation laws do not allow for current relaxation to leading --second--order in T/E_F (E_F is the Fermi energy). If the T^2 term is nullified by the conservation law, the first non-zero term behaves as T^4. The same applies to a quantum-critical metal in the vicinity of a Pomeranchuk instability, with a proviso that the leading (first non-zero) term in the resistivity scales as T^{\frac{D+2}{3}} (T^{\frac{D+8}{3}}). We discuss a number of situations when integrability is weakly broken, e.g., by inter-plane hopping in a quasi-2D metal or by warping of the FS as in the surface states of Bi_2Te_3 family of topological insulators.
DEVELOPMENT AND LIFE TABLE PARAMETERS OF TETRANYCHUS TURKESTANI (ACARINA: TETRANYCHIDAE) AT DIFFERENT CONSTANT TEMPERATURES

Selected life history characteristics of the strawberry spider mite (Tetranychus turkestani Ugarov and Nikolski, Acarina: Tetranychidae) were studied at four constant temperatures (15, 20, 25 and 30 °C). Egg-to-adult developmental time of females ranged from 50.11 +/- 0.79 days at 15 °C to 7.73 +/- 0.14 days at 30 °C. An average of 140.33 +/- 5.49 degree-days was required to complete development above the lower thermal threshold (11.89 °C). Preimaginal mortality was 62.92, 16.67, 41.82 and 42.31% at 15, 20, 25 and 30 °C, respectively. Mean longevity of female T. turkestani ranged from 30.22 +/- 2.88 days at 15 °C to 5.78 +/- 0.10 days at 30 °C. Mean total fecundity ranged from 23.11 +/- 3.14 to 49.95 +/- 5.54 eggs / female. The sex ratio (% females) ranged from 69.00 +/- 0.04 to 83.01 +/- 0.02%. The intrinsic rate of population increase (rm) ranged from 0.272 +/- 0.010 at 30 °C to 0.033 +/- 0.002 (female per female per day) at 15 °C. The population doubled most quickly at 30 °C (2.54 +/- 0.09 d) and most slowly at 15 °C (20.46 +/- 1.59 d). Based on these results, we can predict the presence of the different stages of the strawberry spider mite on cucumber over time. This information will therefore enable us to determine more precisely the best time to control this pest.
New perspectives on realism, tractability, and complexity in economics

Fuzzy logic and genetic algorithms are used to rework more realistic (and more complex) models of competitive markets. The resulting equilibria are significantly different from the ones predicted from the usual static analysis; the methodology solves the Walrasian problem of how markets can reach equilibrium, starting with firms trading at disparate prices. The modified equilibria found in these complex market models involve some mutual self-restraint on the part of the agents involved, relative to economically rational behaviour. Research (using similar techniques) into the evolution of collaborative behaviours in economics, and of altruism generally, is summarized; and the joint significance of these two bodies of work for public policy is reviewed. The possible extension of the fuzzy/ genetic methodology to other technical aspects of economics (including international trade theory, and development) is also discussed, as are the limitations to the usefulness of any type of theory in political domains. For the latter purpose, a more differentiated concept of rationality, appropriate to ill-structured choices, is developed. The philosophical case for laissez-faire policies is considered briefly; and the prospects for change in the way we ‘do economics’ are analysed.
Why Nominal-Typing Matters in Mainstream OOP

In 1990, Cook et al. shocked the programming languages (PL) research community by declaring that, in object-oriented programming, ‘inheritance is not subtyping,’ meaning there is no one-to-one correspondence between the two notions in OO programming languages, further adding that mainstream OO languages unnecessarily ‘place restrictions over inheritance. ’ Over the years, these statements rippled, as mantras, through the PL research community. To this day, however, many mainstream OO developers and OO language designers cannot digest or accept not identifying type inheritance with subtyping. Simply, the statement of Cook et al. is not true in nominally-typed OO languages such as Java, C#, C++ and Scala that these developers and language designers are dearly familiar with. Further, they see that the so-called “restriction” of type inheritance in these languages is strongly justified, or, more so, that a structural view of inheritance is in fact an unjustified redefinition of inheritance, which they view as an inherently nominal notion. Nominally-typed OO languages are among the top most-used programming languages today. In spite of that, the value of nominal typing and nominal subtyping to mainstream OO developers, as a means for designing robust OO software, as well as the value of properties of OO type systems that depend on nominality (such as the identification of type inheritance with subtyping), seem to be not yet fully appreciated among PL researchers—perpetuating an unnecessary tension and schism between two large and significant communities: many mainstream OO developers and language designers, on one side, and many OO PL researchers, on the other side, with each of both sides discounting, if not even disregarding, the views and opinions of the other. In this essay we complement and strengthen earlier efforts that aimed to demonstrate the semantic value of nominal typing, particularly the association of class names with behavioral class contracts, by making a technical comparison between nominal OO type systems and structural OO type systems. In other recent work, we also compared NOOP, our domain-theoretic model of nominally-typed OOP, to models of structurally-typed OOP developed and disseminated by Cardelli, Cook, and others. These comparisons provide a clear, deep technical and mathematical account for the relation between nominal and structural OO type systems that, due to earlier lack of a domain-theoretic model of nominally-typed OOP, has not been presented before. They should help further demonstrate, to OO
On the solute transport in an aquifer-aquitard system

On the Solute Transport in an Aquifer-Aquitard System. (May 2007) Aiguo Bian, B.S., Beijing University, China Chair of Advisory Committee: Dr. Hongbin Zhan This dissertation is composed of five chapters and three major contributions are presented in Chapter II, III and IV. Chapter I provided a review of studies on solute transport in aquifer-aquitard system. If the aquitard is considered, two categories of methods address the diffusive flux between the aquifer and aquitard: the old method treats the diffusive flux as a volumetric source in the governing equation of the solute transport in the aquifer; the new method treats the aquifer-aquitard boundary as a strict physical boundary with the requirement of continuity of solute concentration and the vertical flux. The new method is adopted throughout this study. In Chapter II, a review of numerical techniques on Inverse Laplace Transform is provided. By careful comparison between several popular algorithms, the multiple precision Stehfest algorithm is chosen as the method to inverse out solutions on solute transport in Laplace domain throughout this dissertation. In Chapter III, solutions were obtained for two dimensional solute transport in an aquifer-aquitard system with a divergent radial flow field, which can treat different types
Regional governance in rural Australia: An emergent phenomenon of the quest for liveability and sustainability?

Change is inherent to both social and natural systems and their interaction. The complexity of the dynamics of change and uncertainty associated with linked social-natural systems and their multi-scalar and spatially variable nature is widely recognised as adversely impacting on liveability and sustainability in many contexts. Institutions and policies that have traditionally been concerned with managing our social and natural systems for liveability and sustainability are being challenged by the complexity of the policy problems now being faced as well as the growing pace and magnitude of change and the uncertainty that it embodies. An important element of the response to this change is an emerging shift in public policy from uncoordinated hierarchical top-down sectoral or program-specific approaches to more ‘holistic’ regional approaches that emphasise inter-sectoral coordination and cross-scale co-operation. Several disciplines and inter-disciplinary fields have shown an interest in the dynamics of this change identifying the complex, multi-level and nested nature of the governance at the regional or territorial level. Much of this work however has focused on sector-specific issues or particular programmatic policy initiatives, and seldom provides a more holistic examination of the complexity of the overall system of multi-level governance in practice at the regional level and the related challenges and opportunities for supporting livability and sustainability more effectively. Drawing on the concepts of complex systems and adaptive governance in a regional policy context, this paper addresses this gap and reports on the first of three case studies examining the current nature and future options for regional governance in Australia. Based on a case study of the rural and remote region of Central Western Queensland in north-eastern Australia, we examine the nature and emerging trends of the existing system of regional governance and consider its potential for enhancing regional capacity to adapt to change and support liveability and sustainability in rural Australia.
Quality of Grain Maize Stored in of Jimma Zone , Ethiopia

Quality of maize grains (Variety: Bako Hybrid containers (Gombisa and Sacks) for 180 days was studied in two intermediate (IAE)and lowland (LAE) of Jimma zone, Ethiopia. fat, dry matter, total carbohydrate and ash contents were influenced significantly by storage periods in Gombisa (p<0.05). Crude fat under LAE and ash under both ecologies were also influenced by storage (p<0.05) effect of storage containers on dry matter and total carbohydrates in the IAE whereas in LAE appeared insignificant (p>0.05). Grains stored in showed significantly lower dry matter and total carbohydrate contents than in Sacks. The study showed maize grain quality deteriorations in moisture, relative humidity and temperature conditions for maize weevil ( zeamais) and angoumois grain moth (Sitotroga cerealella storage. Copyright@2015 STAR Journal INTRODUCTION Various studies undertaken in sub-Saharan Africa to estimate maize (Zea mays L.) grain losses in traditional storage practices have shown that the losses are generally high. From harvest to consumer market, maize grain postharvest losses in Africa are estimated to range 14 to 36% (Tefera et al., 2011a; Tefera, 2012). In Ghana, about 15 % of maize grains harvested are lost annually due to attacks by maize weevils (Sitophilus zeamais (Baidoo et al., 2010). One in five kg of grain produce in sub-Saharan Africa is estimated to be lost by pest infestations and associated grain decays/ which maize grain loss remained the highest (FAO/NRI, 2011). In Nigeria, Kerstin et al. (2010) reported 10 to 12% loss of maize grains stored in traditional storage containers similar to Gombisa due to insect pests. Loss of about 18% was also reported by the same author in other African countries for maize grain stored in polypropylene sacks for the storage periods of six months. Maize is one of the most important staple food and cash crops in Ethiopia providing calories for the of Wollega University, Ethiopia DOI: http://dx.doi. org/10.4314/star.v4i3. 4 ISSN: 2226-7522(Print) and 2305J. , July-Sep 201 Journal Homepage: http://www.starjournal. org/ Gombisa and Sacks in Selected Districts 2 , Solomon Abera , Geremew Bultosa and Sethumadhavarao G 2
Anthropogenic land cover changes in a GCM with surface albedo changes based on MODIS data

This study uses a global climate model (GCM) to investigate the climate response at the surface and in the atmosphere caused by land use change. The climate simulations are performed with the National Center for Atmospheric Research Community Land Model 3.5 (CLM3.5) coupled to the Community Atmosphere Model 3 (CAM3) and a slab ocean model. We use the Moderate Resolution Imaging Spectroradiometer (MODIS) surface albedo product to represent surface albedo in the CLM3.5 for both present day and to reconstruct the surface albedo for natural pre‐agriculture conditions. We compare simulations including vegetation changes and surface albedo changes to simulations including only surface albedo changes. We find that the surface albedo change is most dominant in temperate regions while the change in evapotranspiration drives the climate response in the tropics. Our results show that land cover changes contribute to an annual global warming of 0.04 K, but there are large regional differences. In North America and Europe, the surface temperatures decrease by − 0.11 and − 0.09 K, respectively, while in India the surface temperatures increase by 0.09 K. When we fix the vegetation cover in the simulations and let the climate changes be driven only by the differences in surface albedo, the annual global mean surface warming is reduced, and all three regions are now associated with surface cooling.
Banana peel in the diet for F1 Holstein x Zebu cows

This study aimed to evaluate the effects of includingsun-dried banana peel in diets for F1 Holstein x Zebu cows on intake, digestibility and milk production. Diets were composed of 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel provided to 10 cows in two simultaneous 5 x 5 Latin squares, with the experiment divided into five periods of 16 days. The dry matter intake showed a quadratic effect with maximum level at 38.30% substitution as well as intake of crude protein expressed in kg-1 day and percentage of body weight, with maximum at the levels of 50.09 and 45.69% inclusion of the peel, respectively. The intake of neutral detergent fiber and the digestibility of neutral detergent fiber and crude protein showed a decreasing linear effect. Variation in weight and body condition score, milk production and feed conversion were not affected. The replacement of 60% sorghum silage with banana peel represents a viable alternative as it causes no change in cows with average production of 16.49 kg milk with 3.5% fat day-1, reducing feeding costs.
Tensile properties of single oil palm empty fruit bunch (OPEFB) fibre.

The use of natural fibres obtained from plants and trees as reinforcing materials has attracted many researchers to widen their applications. Natural fibres are low cost, low density, have high specific properties, biodegradable and non-abrasive. Oil palm fibre (OPF) can be obtained directly from natural resource, it is cheap and also has advantages due to its renewable nature, low cost, and easy availability. In this study, the mechanical performances of single oil palm fibre are measured and evaluated. The diameter of OPF was in the range from 250 to 610 μm while moisture content was between 2.2 to 9.5%. The average tensile properties obtained were tensile strength, 71 MPa, Young’s modulus, 1703 MPa and elongation at break, 11%.
Corporate governance mechanisms and firm performance: Evidence from Greek manufacturing sector

Corporate governance is a fairly new concept which has been put into practice because of the needs of companies to constantly perform better; and it is this need that has made corporate governance so necessary today. As a set of limitations which must be adhered to in order for a company or firm to reach its optimal performance, corporate governance is a process which ensures growth for a firm and the economy. This paper surveys research on corporate governance of listed manufacturing firms in Greece. A critical analysis based on the available literature is introduced, relatively whether the size of board of directors and ownership structure is related to firm performance. The necessary information for the analysis was collected using secondary data. The listed manufacturing Greek firms were selected based on criteria such as high development rate, high capitalization breadth, and a sufficient enforcement of the principles of corporate governance. The basic hypotheses to be tested were: i) companies that have an expanding Board of Directors have better internal control and thus they perform better than companies, which have a limited number of members in the Board of Directors, ii) firms which belong to an expanded group of shareholders perform better than those firms which belong to a small group of shareholders or are family owned. According to the findings of the research, we can not fully accept the two hypotheses, since some ratios are better in companies which implement the aforementioned corporate governance principles, while the remaining do not seem to present any particular difference due to the implemented principles of corporate governance.
Toward a phylogenetic-based Generic Classification of Neotropical Lecythidaceae— I. Status of Bertholletia, Corythophora, Eschweilera and Lecythis

Lecythidaceae subfam. Lecythidoideae is limited to the Neotropics and is the only naturally occurring subfamily of Lecythidaceae in the New World. A subset of genera with zygomorphic flowers— Bertholletia , Corythophora , Eschweilera and Lecythis —comprises a group of about 125 species called the Bertholletia clade. A previous study based on plastid ndhF and trnL - F genes supported the monophyly of Corythophora but suggested that Eschweilera and Lecythis are not monophyletic. Using this study as a baseline, we sampled more taxa and sequenced more loci to address the taxonomic problems of the ambiguous genera and to determine relationships within the Bertholletia clade. Our results support the monophyly of the Bertholletia clade as previously circumscribed. In addition, Corythophora is monophyletic, and the two accessions of Bertholletia excelsa come out together on the tree. Results of the simultaneous analysis do not support the monophyly of Lecythis or Eschweilera . Lecythis consists of four main groups (the Lecythis pisonis , L . poiteaui , L. chartacea , and L. corrugata clades), the last of which is nested within Eschweilera , and Eschweilera consists of three clades (the Eschweilera integrifolia , E . tetrapetala , and Eschweilera parvifolia clades). We compare our results with the generic classification presented in the latest monograph of neotropical Lecythidaceae and make recommendations for a revised generic classification of the Bertholletia clade of Lecythidaceae.
Estimating carbon sequestration cost function for developing countries

Carbon sequestration is considered as the cost effective way of reducing carbon dioxide emission and other greenhouse gases. This study estimated the carbon sequestration cost function considering land use change in developing countries. Using the instrumental variable method, this study found that the percentage change in the cost due to the percentage change in carbon sequestration is almost unitary. The result also shows that the presence of Clean Development Mechanism (CDM) project in a country and per capita GDP in purchasing power parity (GDP, ppp) have positive influence on the carbon sequestration cost function. The marginal cost calculated from the total cost function representing the unit price of carbon dioxide is very low compared with the marginal abatement cost of the developed countries but equals the price at the European CO2 emission trading market.
A nation-and gendered-based study about the relationship between the Big Five and motives for Internet use : A Hungarian and Israeli comparison

Objective: Personality psychology has for many years been looking for a taxonomy permitting the study of specified personality characteristics. The Big Five structure captures the common existing systems of personality description, and provides an integrative descriptive model for personality research. The way people are behaving when using the Internet, the Internet motives they have, and the choices they are making then, is very much determined by their individual characteristics. The purpose of the study was to investigate the relationship between the motives for Internet uses and the Big Five personality characteristics. Method : 300 medical students filled out questionnaires connected to Internet motives, Internet affinity and the brief 44-items BFI (the Big Five Inventory; John, 1990). The sample consisted of 150 Hungarian (75 males and 75 females) and 150 Israeli (75 males and 75 females) medical students. Results: There were significant gender differences in the Israeli sample between the Big Five and Internet motives. The results showed that the Israeli males and females were both high on agreeableness and the Internet motive of habit. Furthermore, the Israeli students scoring high on the personality factor of neuroticism also scored high on the Internet motive of companionship. When it came to the Hungarian sample, students scored highest on conscientiousness, but the males and females scored high on different Internet motives. This means that conscientious Hungarian males obtained higher scores for the companionship motive, while the conscientious Hungarian females scored high on the Internet motive of pass time. Internet affinity significantly correlated with extraversion and neuroticism for the Israeli sample but not for the Hungarian sample. Our results suggest that personality characteristics have important effects on Internet uses. 1 General Internet Use The history of the Internet goes back to the mid 1960s when the US Defense Department took the initiative to develop a distributed network of computers. This network of computers originally began as a way to share only data and the original intention of the Internet, which was called Arpanet at that time, was to provide links between the computers and not between people. Interestingly the e-mail was developed at an early stage by the users of the Arpanet to be able to use it for person-to-person, instead of for computer-to-computer, communication. The World Wide Web developed rapidly in the early 1990s and the web browsers were commercially released in 1993-1994. With these two important changes the Internet began to expand rapidly and it started to attract an increasing number of commercial organizations and private users. Since then, the Internet has been an ever-growing technology for everybody from professionals to laypersons (Joinson, 2002). ∗Both authors have contributed with fifty percent to this publication
