Valorisation of sugarcane bagasse ash ( SCBA ) with high quartz content as pozzolanic material in Portland cement mixtures

Portland cement (OPC) production is one of the most contaminating greenhouse gas producing activities. In order to reduce OPC consumption, several alternatives are being assessed, and the use of pozzolanic material is one of them. This paper presents study on the reactivity of sugarcane bagasse ash (SCBA), a residue from sugarcane industry, as a pozzolanic material. In order to evaluate SCBA reactivity, it was mixed in pastes with hydrated lime and OPC, which were microstructurally characterised. These studies showed that SCBA presents some pozzolanic characteristics. Studies on mortars in which OPC was replaced by SCBA in the range 10–30% were also carried out. Replacement in the range 15–20% yielded the best behaviour in terms of compressive strength. Finally, it can be concluded this ash could be valorised despite its relative low pozzolanic reactivity.

English-written abstracts for Spanish publications

The preeminence of English as the scientific lingua franca, together with the ever-present publish-or-perish dilemma, has brought increasing concern on Spanish scientists striving to achieve international recognition. Spanish journal editors try to make their journals look as professional as possible, most of them peer reviewed and their abstracts are listed in the most important databases. However, the problem of language seems to be the issue around which the dissemination of their publications is centered. In this report we examine the English-written abstracts of the Spanish Journal of Finance and Accounting, their content and form, and whether or not they are persuasive enough to lure the researcher into reading the paper. While the abstract is considered the first point of contact with the researcher, the expected results will show a rather irregular rendering of the information and, in general, a defective composition of the abstracts, in addition to local issues discussed in their articles. These results suggest a poor dissemination and repercussion of the authors’ contribution worldwide.
Dynamics of Humoral Immunity Indices and of Haematological Variables in Rabbits Immunized with Chlamydophila psittaci

Introduction. The research of humoral immunity in infection or immunization with Chlamydophila psittaci in sta− tic models showed changes in parameters of this immunity. Objectives. Evaluation of chosen parameters of humoral immunity in dynamic model in rabbits immunized with Chlamydophila psittaci. Material and Methods. The studies were performed on rabbits divided into two groups of 10 animals each. The rabbits of first group were immunized with Chlamydophila psittaci – strain 6BC, and the animals of second group were control animals. Blood samples were examined 9 times every 7 days. The activity of myeloperoxidase in polymorphonuclear leukocytes (PMN), amount and activity of lysozyme, total amount of immunoglobulins (Ig), including those of IgG class were estimated in sera of rabbits immunized with Chlamydophila psittaci. Haemoglobin level, content of erythrocytes and leukocytes, blood differential count and titre of Chlamydia spp. − −specific antibodies were also established by complement−fixation technique. Results. The results indicate that immunization of rabbits with the bacteria induces with a similar frequency increase or decrease in 2 out of 6 examined parameters of humoral immunity (amount and activity of lysozyme) and rather a decrease than increase in 3 out of 8 examined haematological variables (count of neutrophiles, basophiles and monocytes). The alterations, mainly those in immune parameters, could be noted 5 weeks before appearance of Chlamydia spp. −specific antibodies, which appeared on 49th–56th day of the experiment. Conclusion. The alterations noted in parameters of humoral immunity, may turn to be useful in determining the condition of macro−organisms in contact with Chlamydophila psittaci (Adv Clin Exp Med 2006, 15, 2, 285–291).
GERMINATION OF THREE LEGUMES: ONOBRYCHIS SUBNITENSE BORNM., ONOBRYCHIS SCROBICULATA BOISS., AND VICIA VARIABILIS GROSSH. AT DIFFERENT TEMPERATURES

Cardinal temperatures and thermal time are valuable information for scheduling year-round production of seed-propagated species. In this study, thermal germination behavior of three species of the family Fabaceae, Onobrychis subnitens Bornm. , Onobrychis scrobiculata Boiss. and Vicia variabilis Grossh. , from Kurdistan Province, Iran were quantified. Seeds of these species were germinated at temperatures of 5– 35°C. Three nonlinear regression models (segmented, beta, and dent-like) were used to estimate cardinal temperatures. After examining O.subnitens, findings showed that the segmented model is the best model for predicting cardinal temperatures. The base, optimum, and maximum temperatures were 1.23, 17.22 and 41.10°C, respectively. The thermal time required for 50% germination was 21.29 degree-days. For O.scrobiculata, segmented and dent-like models were equal. The base, optimum and maximum temperatures of seed germination were 5.5, 18.8–19.76 and 38.14°C, respectively. The thermal time required for 50% germination was 25.87 degree-days. For V.variabilis, there was no difference between the segmented and dentlike models and each one could be chosen. Accordingly, the base, optimum, and maximum temperatures of seed germination were -1.2, 20 and 35.13°C, respectively. The thermal time required for 50% germination was 60.9 degree-days. Based on the germination percentage, germination rate and thermal time requirement, O.subnitens is preferred for use in the arid and semi-arid rangeland improvement project.

In arid regions the rainfall is highly variable temporally and spatially. Statistical frequency analyses help to extract design rainfall intensity for different return periods. Wadi Alaqiq catchment at Madinah region in the Kingdom of Saudi Arabia is selected to estimate the frequency of the daily rainfall, where there are two rainfall stations (Madinah and BirMashi) with more than 40-year annual maximum daily rainfall magnitudes. Several probability distribution functions are tested through goodness-of-fit (GOF). Anderson-Darling (AD) test is applied to select the best statistical distribution and L-moments method is applied for parameters estimation. The generalized logistic and generalized extreme value PDFs are the best for this arid region data for both stations. The findings are useful for application of flood frequency analysis in arid region with similar conditions of hydrological systems. In the mean-time, the climate change effects have been explained through the innovative trend analysis.
Role of the endothelial cell protein C receptor in thrombosis

The protein C anticoagulant pathway plays a crucial role as a regulator of the blood coagulation cascade. The endothelial protein C receptor (EPCR) was first revealed as the key molecule for efficient protein C activation, displaying its essential role in haemostasis. However, the discovery of the cytoprotective functions of activated protein C and the requirement of EPCR in the endothelial cell membrane scenario to activate the signaling cascades, highlighted EPCR as a molecule of paramount importance in the crosstalk between coagulation and inflammation. The recent discovery of novel EPCR ligands has widened the perspective in the search of new EPCR functions. The interaction of EPCR with FVII/FVIIa and FX/FXa might result in physiologically relevant consequences. Additionally, many efforts are being made to elucidate the association of PROCR polymorphisms with the risk of thrombosis, alone or in combination with other risk factors. This review highlights the role of the endothelial protein C receptor in disease and discusses the association of its mutations with the risk of thrombosis.
Diffusion of student business incubators : An institutional theory perspective on the emergence of a hybrid organizational form

This paper undertakes a longitudinal examination of the diffusion of a relatively new organizational activity ? university student business incubators ? by studying the processes through which actors grounded in three different institutional logics interact in the organizational field of higher education. Applying neo-institutional theory, we examine the development of student incubation activities in the field of general state-funded Danish universities. We review institutional pressures from the political sphere that led to the diffusion of student incubation, introducing a three-phase process involving experimentation, demonstration, and integration. Our study shows that universities? responses changed over the period from initial coercive isomorphism and structural and functional decoupling of incubation from core activities towards a higher degree of integration, although still loosely coupled. The process was facilitated by the institutional logic of entrepreneurial culture that integrated elements of the commercial and classic university logics. We find that the diffusion and adaptation process were mainly influenced by resources available, organizational constituencies mobilized, discretional power, and congruity between competing logics. Our findings have theoretical and empirical implications for the development of entrepreneurial promotion activities associated with pre-existing institutional structures as well as the political/institutional dimensions of entrepreneurship relative to the role of the contemporary university.

The Higgs-inflaton coupling plays an important role in the Higgs field dynamics in the early Universe. Even a tiny coupling generated at loop level can have a dramatic effect on the fate of the electroweak vacuum. Such Higgs-inflaton interaction is present both at the trilinear and quartic levels in realistic reheating models. In this work, we examine the Higgs dynamics during the preheating epoch, focusing on the effects of the parametric and tachyonic resonances. We use lattice simulations and other numerical tools in our studies. We find that the resonances can induce large fluctuations of the Higgs field which destabilize the electroweak vacuum. Our considerations thus provide an upper bound on quartic and trilinear interactions between the Higgs and the inflaton. We conclude that there exists a favorable range of the couplings within which the Higgs field is stabilized during both inflation and preheating epochs.
Endo-trivial modules for finite groups with dihedral Sylow 2-subgroup

Abstract We provide a description of the torsion subgroup 𝑇𝑇 ⁢ ( G ) ${\mathit{TT}(G)}$ of the finitely generated abelian group T ⁢ ( G ) ${T(G)}$ of endo-trivial kG-modules in the case that G has a dihedral Sylow 2-subgroup of order at least 8 and k is an algebraically closed field of characteristic p = 2 ${p=2}$ . Specifically, we prove that 𝑇𝑇 ⁢ ( G ) ≅ X ⁢ ( G ) ${\mathit{TT}(G)\cong X(G)}$ , the group of one-dimensional kG-modules, except possibly when G / O 2 ′ ⁢ ( G ) ≅ 𝔄 6 ${G/O_{2^{\prime}}(G)\cong{\mathfrak{A}}_{6}}$ , the alternating group of degree 6; in which case G may have nine-dimensional simple torsion endo-trivial modules. Our results complement the tame-representation type investigation of endo-trivial modules started by Carlson–Mazza–Thévenaz in the cases of semi-dihedral and generalized quaternion Sylow 2-subgroups. Furthermore, we provide a general reduction result, valid at any prime p, to recover the structure of 𝑇𝑇 ⁢ ( G ) ${\mathit{TT}(G)}$ from the structure of 𝑇𝑇 ⁢ ( G / H ) ${\mathit{TT}(G/H)}$ , where H is a normal p ′ ${p^{\prime}}$ -subgroup of G.
Chaotic advection and mixing by a pair of rotlets in a circular domain

In this work we study chaotic mixing induced by point micro-rotors in a bounded two dimensional Stokes ﬂow. The dynamics of the pair of rotors, modeled as rotlets, are non Hamiltonian in the bounded domain and produce chaotic advection of ﬂuid tracers in subsets of the domain. A complete parametric investigation of the ﬂuid mixing as a function of the initial locations of the rotlets is performed based on pseudo phase portraits. The mixing of ﬂuid tracers as a function of relative positions of micro-rotors is studied using ﬁnite time entropy and locational entropy. The ﬁnite time locational entropy is used to identify regions of the ﬂuid that produce good vs poor mixing and this is visualized by the stretching and folding of blobs of tracer particles. Unlike the case of the classic blinking vortex dynamics, the velocity ﬁeld of the ﬂow modeled using rotlets inside a circular boundary is smooth in time and satisﬁes the no slip boundary condition. This makes the considered model a more realistic case for studies of mixing in microﬂuidic devices using magnetic actuated microspheres. argument of each
Magisterarbeit International Environmental Agreements under Incomplete Contracts

The thesis analyses international environmental agreements (IEAs) in a static game setting expanding on standard modelling practices regarding two components. Firstly, incomplete contracts account for the abundance of multilateral environmental treaties currently in force. Countries may sign binding agreements on investments in clean technology while abatement efforts remain non-contractible. Secondly, abatement efforts are assumed to be strategic complements. Countries reduce their emissions in reaction to unilateral abatement due to international competitive re-enforcement effects. In this framework, second-best investments lie below ex-post efficient levels to induce a higher level of abatement. Building on the property rights literature, the thesis provides a tool for analysing emissions and investments yielding insights into the design of effective IEAs. I am grateful to my supervisor Gerhard Sorger for his expeditious feedback, instructive remarks and patience. Moreover, I want to thank Immanuel Bomze for supporting my venture into academia and the confidence he gave me when it turned out differently. My sincere thanks goes to Chris Skeels and Lawrence Uren for challenging academic experiences, inspiration and helping me to achieve my goals. I am thankful to my family for giving me the opportunity to pursue my dreams and supporting me on every step of the way. Finally, my deepest gratitude goes to Kathi for living through every facet of this experience with me.
ECOTOURISM AS AN INTEGRAL PART OF SUSTAINABLE TOURISM DEVELOPMENT

The authors of the article analyze ecotourism as an integral part of sustainable tourism development. The paper presents ecotourism as one of the fastest growing types of tourism in the world. Ecotourism as a sustainable development tool provides long-term social, environmental and economic benefits and is given appropriate priority in the country's economic development. The main aspects of ecotourism are economical, ecological, social and cultural. Political aspect and marketing changes influence ecotourism development as well. The paper presents the main elements involved in the ecotourism development: the respect for the ecosystem integrity, local participation and economic opportunities for the local community. SWOT analysis shows that ecotourism not only has many advantages in Lithuania, which allow it to exist successfully, but also drawbacks that hinder the development of ecotourism. Despite the fact that most of the threats may also be a barrier to development, there are a few opportunities that provide the development of ecotourism perspectives in Lithuania. Exploring the factors, which influence the development of ecotourism, the Lithuanian ecotourism SWOT analysis was conducted, which shows the direction in which the rapidly developing ecotourism could successfully compete not only in the Lithuanian but also in the international tourism market. The type of the article: Theoretical paper.

Wor King Papers Economics Working Papers 2012-05 Trade Liberalization , Mergers and Acquisitions , and Intra-Industry

This paper presents a Melitz-type model of international trade in final goods and Grossman-Hart-Antràs input sourcing by heterogeneous firms. We show how firms self-select into different organizational forms in a continuum of industries with different characteristics. Next, we show how a liberalization of trade leads to short run increases in the number of firm mergers and acquisitions and potentially new gains from trade. Finally, we show how the relative prevalence of integrating firms is increasing in some industries while constant in all others.
TENSILE MECHANICAL PROPERTIES OF POLYPROPYLENE COMPOSITES FABRICATED BY MATERIAL EXTRUSION

In the material extrusion additive manufacturing process, a thin filament of material is deposited in a layer-by-layer manner to fabricate a three dimensional part. The filament deposition pattern can result in voids and incomplete bonding between adjacent filaments in a part, which leads to reduced mechanical properties. Further, the layer-by-layer deposition procedure typically results in mechanical property anisotropy, with higher properties in the layer compared to those across layers. The study reported in this paper explored various polypropylene composite formulations to address these issues: low residual stress and warpage, good mechanical properties, and reduced anisotropy. The reduction in anisotropy will be the focus of this paper as a function of thermal properties and process variable settings. A series of process simulation models was developed to explore ranges of thermal properties and process settings, which provided insights into tensile specimen behaviors. Results demonstrate that anisotropy can be reduced almost completely if the material can be formulated to have low crystallinity, low coefficient of thermal expansion, and moderate to high thermal conductivity (for a polymer).

Determinants of systematic risk in the Iranian Financial sector

In this research, we use jump beta and continuous beta as indicators of financial sector companies systematic risk and study their determinants in banking, insurance and investment industry. In result, the value of jump beta is higher than continuous beta. Jump beta of Banking industry and Investment industry is considerably lower than average. We found some negative and positive effects of firm characteristics on jump beta and continuous beta. In insurance companies, the supremacy of jump beta is influenced by firm characteristics. Size has positive effect on aggressiveness of both continuous and jump betas in investment companies. Current ratio has positive effect and debt ratio has negative effect on aggressiveness of insurance companies. Firm characteristic has some positive and negative effects on continuous industry beta deviation, but no effect on jumpy one. Inflation has negative effect on continuous beta but has no considerable effect on jump beta. Inversely, exchange rate has negative effect on jump beta but has no sensible effect on continuous beta. Influence of growth rate is strong positive for all industries of financial sector but weak positive for banking and insurance companies
H3+ as an ionospheric sounder of Jupiter and giant planets: an observational perspective

Thirty years of observations of H3+ on Jupiter have addressed many complex questions about the physics of the ionospheres of the giant planets. Spectroscopy, imaging and imaging spectroscopy in the infrared have allowed investigators to retrieve fundamental parameters of the ionosphere, overcoming the inherent limitations and complexities in radiative transfer, and these results are now introduced as model constraints for upper atmospheric structure and dynamics. This paper will focus on the mid-latitude emissions, which are fainter and less well studied than the auroral regions. A new analysis of VLT/ISAAC spectral imaging observations of Jupiter obtained in 2000 at 3.5 µm is presented and discussed in comparison with previous observations to show the spatial distribution of H3+ emissions compared with other atmospheric structures. Cylindrical maps of Jupiter in three different selected wavelengths show the spatial variations at different altitudes in the atmosphere, from cloud level up to the ionosphere. Evidence for fluctuations in the H3+ emissions could be due to the presence of stationary or dynamic processes. If the exact origin of these phenomena remains unidentified, several plausible mechanisms are proposed to explain the observed energy deposition and variability: future observation campaigns should deepen the understanding of these complex phenomena, in order to prepare for the future ESA/JUICE mission. This article is part of a discussion meeting issue ‘Advances in hydrogen molecular ions: H3+, H5+ and beyond’.
