Published: October 2016

ABSTRACTThe alternative sigma factor D is known to be involved in at least three biological processes in Bacilli: flagellin synthesis, methyl-accepting chemotaxis and autolysin synthesis. Although many Bacillus genes have been identified as SigD regulon, the list may be not be complete. With microarray-based systemic screening, we found a set of genes downregulated in the sigD knockout mutant of the plant growth-promoting rhizobacterium B. amyloliquefaciens subsp. plantarum FZB42. Eight genes (appA, blsA, dhaS, spoVG, yqgA, RBAM_004640, RBAM_018080 and ytk) were further confirmed by quantitative PCR and/or northern blot to be controlled by SigD at the transcriptional level. These genes are hitherto not reported to be controlled by SigD. Among them, four genes are of unknown function and two genes (RBAM_004640 and RBAM_018080), absent in the model strain B. subtilis 168, are unique to B. amyloliquefaciens stains. The eight genes are involved in sporulation, biofilm formation, metabolite transport and several other functions. These findings extend our knowledge of the regulatory network governed by SigD in Bacillus and will further help to decipher the roles of the genes.
Numerical synthesis of ionograms in horizontally inhomogeneous ionosphere on the basis of compound parabolic layer model
Authors: Ларюнин Олег , Laryunin Oleg 
Published: October 2016

Characteristic U-shaped traces (cusps) on ionograms have been identified as off-angle echoes from sloping electron density contours caused by the presence of traveling ionospheric disturbances (TIDs). Temporal evolution of the cusps is associated with horizontal drift of the disturbances.
A potential for reducing calculation time in numerical synthesis of vertical ionograms is under discussion.
Since numerical ray tracing is computationally intensive, we have developed simplified formulation for this study. The suggested model of compound parabolic layer allows us to analytically calculate ray paths. Changes in the shape of the ionogram cusp caused by varying TID characteristics are examined.
The Impact of Idea Generation and Potential Appropriation on Entrepreneurship: An Experimental Study
Authors: Hooshangi Soheil , Loewenstein George 
Published: October 2016

Using a novel experimental paradigm, we explore how the experience of generating an idea and the possibility that another investor might adopt a rejected investment opportunity, bias the investment decisions of innovator and imitator entrepreneurs. We find that individuals who generate a business idea form biased evaluations of the economic potential of ideas, be it their own idea or somebody else’s idea. On the one hand, they are overconfident about the value of, and overly likely to invest in, their own idea. On the other hand, when investing in another person’s idea, even if it is not competing with their own idea, they are underconfident about the value of, and insufficiently likely to invest in, the idea. Surprisingly, we find that entrepreneurial experience exacerbates this pattern of over- and underconfidence. In addition, we find that the threat that another investor can appropriate a declined investment opportunity increases willingness to invest. We propose a theoretical account to explain the observed pattern of over- and underconfidence in imitative and innovative entrepreneurship. Our findings challenge the traditional account that lowering the cost of imitation has a disincentive effect on the investment decisions of pioneer entrepreneurs and provide evidence that a more lenient appropriability regime may, unexpectedly, have positive effects on entrepreneurship. Our findings also identify new psychological mechanisms that can play a role in important phenomena such as the emergence of spin-offs and rush to market entry.

Abstract
The discovery that melting sea ice can fertilize iron (Fe)-depleted polar waters has recently fostered trace metal research efforts in sea ice. The aim of this review is to summarize and synthesize the current understanding of Fe biogeochemistry in sea ice. To do so, we compiled available data on particulate, dissolved, and total dissolvable Fe (PFe, DFe and TDFe, respectively) from sea-ice studies from both polar regions and from sub-Arctic and northern Hemisphere temperate areas. Data analysis focused on a circum-Antarctic Fe dataset derived from 61 ice cores collected during 10 field expeditions carried out between 1997 and 2012 in the Southern Ocean. Our key findings are that 1) concentrations of all forms of Fe (PFe, DFe, TDFe) are at least a magnitude larger in fast ice and pack ice than in typical Antarctic surface waters; 2) DFe, PFe and TDFe behave differently when plotted against sea-ice salinity, suggesting that their distributions in sea ice are driven by distinct, spatially and temporally decoupled processes; 3) DFe is actively extracted from seawater into growing sea ice; 4) fast ice generally has more Fe-bearing particles, a finding supported by the significant negative correlation observed between both PFe and TDFe concentrations in sea ice and water depth; 5) the Fe pool in sea ice is coupled to biota, as indicated by the positive correlations of PFe and TDFe with chlorophyll a and particulate organic carbon; and 6) the vast majority of DFe appears to be adsorbed onto something in sea ice. This review also addresses the role of sea ice as a reservoir of Fe and its role in seeding seasonally ice-covered waters. We discuss the pivotal role of organic ligands in controlling DFe concentrations in sea ice and highlight the uncertainties that remain regarding the mechanisms of Fe incorporation in sea ice.
Gait analysis of patients with knee osteoarthritis highlights a pathological mechanical pathway and provides a basis for therapeutic interventions
Authors: Favre Julien , Jolles Brigitte M. 
Published: October 2016

Knee osteoarthritis (OA) is a painful and incapacitating disease affecting a large portion of the elderly population, for which no cure exists. There is a critical need to enhance our understanding of OA pathogenesis, as a means to improve therapeutic options. Knee OA is a complex disease influenced by many factors, including the loading environment. Analysing knee biomechanics during walking - the primary cyclic load-bearing activity - is therefore particularly relevant. There is evidence of meaningful differences in the knee adduction moment, flexion moment and flexion angle during walking between non-OA individuals and patients with medial knee OA. Furthermore, these kinetic and kinematic gait variables have been associated with OA progression. Gait analysis provides the critical information needed to understand the role of ambulatory biomechanics in OA development, and to design therapeutic interventions. Multidisciplinary research is necessary to relate the biomechanical alterations to the structural and biological components of OA. Cite this article: Favre J, Jolles BM.

External Morphology of Immatures of Mischocyttarus nomurae Richards (Hymenoptera, Vespidae) during the Post-embryonic Development
Authors: Rocha Agda Alves , Giannotti Edilberto 
Published: October 2016

The work on this paper aimed to perform the description of the immatures and determine the number of larval instars in the post-embryonic development of Mischocyttarus nomurae Richards, a social wasp which the only works performed were the description of the specie and of the male. Twenty colonies were collected in the city of Rio de Contas, in the region of the Chapada Diamantina, Bahia, Brazil and there were dimensioned 145 eggs, 349 larvae, 12 pre-pupae and 59 pupae. The eggs presented an average length of 1.03 ± 0.12mm and diameter of 0.40 ± 0.03mm. The average rate of growth of the larvae that presented five instars was 1.49. The width of the cephalic capsule of the larvae was: 1st instar 0.32 ± 0.08, 2nd instar 0.54 ± 0.06, 3rd instar 0.77 ± 0.07, 4th instar 1.05 ± 0.10 and 5th instar 1.55 ± 0.07. The average width of the larvae of 5th instar and pre-pupae were close, where larvae of the 1st instar differed from the egg, being smaller. The average measure of the pupae was 1.85 ± 0.08. The specie presents two abdominal lobes highly projected towards and the first thoracic spiracle is 3.1 times higher than the second one. This is the first work on the biology of the specie.
In vitro application of integrated selection index for screening drought tolerant genotypes in common wheat
Authors: FARSHADFAR Ezatollah , Amiri Reza 
Published: October 2016

This experiment was conducted on 20 wheat genotypes during 2010-2011 growing season at the Razi University, Kermanshah, Iran. A completely randomized design with six replications was used for callus induction and a 20 × 2 factorial experiment with three replications was used for response of genotypes to in vitro drought stress. ANOVA exhibited highly significant differences among the genotypes for callus growth rate, relative fresh mass growth, relative growth rate, callus water content, percent of callus chlorosis and proline content under stress condition (15 % PEG). PCA showed that the integrated selection index was correlated with callus growth index, relative fresh mass growth, relative growth rate and proline content indicating that these screening techniques can be useful for selecting drought tolerant genotypes. Screening drought tolerant genotypes and in vitro indicators of drought tolerance using mean rank, standard deviation of ranks and biplot analysis, discriminated genotypes 2, 18 and 10 as the most drought tolerant. Therefore they are recommended to be used as parents for genetic analysis, gene mapping and improvement of drought tolerance.
The effects of intermittent negative pressure on the lower extremities' peripheral circulation and wound healing in four patients with lower limb ischemia and hard‐to‐heal leg ulcers: a case report

Published: October 2016

AbstractPeripheral circulation is severely compromised in the advanced stages of peripheral arterial disease. Recently, it was shown that the application of −40 mmHg intermittent negative pressure (INP) to the lower leg and foot enhances macro‐ and microcirculation in healthy volunteers. In this case report, we describe the effects of INP treatment on four patients with lower limb ischemia and hard‐to‐heal leg and foot ulcers. We hypothesized that INP therapy may have beneficial hemodynamic and clinical effects in the patients. Four patients (age range: 61–79 years) with hard‐to‐heal leg and foot ulcers (6–24 months) and ankle‐brachial pressure indices of ≤0.60 on the affected side were included. They were treated with an 8‐week intervention period of −40 mmHg INP (10 sec negative pressure and 7 sec atmospheric pressure) on the lower limbs. A custom‐made vacuum chamber was used to apply INP to the affected lower leg and foot for 2 h per day. After 8 weeks of INP therapy, one ulcer healed completely, while the other three ulcers were almost completely healed. These cases suggest that INP may facilitate wound healing. The theoretical foundation is that INP assists wound healing by improving blood flow to the small blood vessels in the affected limb, increasing the flow of oxygen and nutrients to the cells.
Antibiotics in WWTP discharge into the Chaobai River, Beijing

Published: October 2016

Abstract22 representative antibiotics, including 8 quinolones (QNs), 9 sulfonamides (SAs), and 5 macrolides (MCs) were selected to investigate their occurrence and removal efficiencies in a Wastewater Treatment Plant (WWTP) and their distribution in the receiving water of the Chaobai River in Beijing, China. Water quality monitoring was performed in an integrated way at different selected points in the WWTP to explore the potential mechanism of antibiotics removal during wastewater treatment. Water quality of the Chaobai River was also analyzed to examine environmental distribution in a river ecosystem. The results showed that within all the 22 compounds examined, 10 antibiotics were quantified in wastewater influent, 10 in effluent, and 7 in river. Sulfadiazine (SDZ, 396 ng/L) and Sulfamethazine (SMZ, 382 ng/L) were the dominating antibiotics in the influent. Both the conventional treatment and advanced Biological Aerated Filter (BAF) system was important for the removal of antibiotics from the wastewater. And the concentrations of selected antibiotics were ranged from 0-41.8 ng/L in the effluent-receiving river. Despite the fact that the concentrations were reduced more than 50% compared to effluent concentrations, WWTP discharge was still regarded as a dominant point-source input of antibiotics into the Chaobai River.
Effects of silver nanoparticles of different sizes on cytotoxicity and oxygen metabolism disorders in both reproductive and respiratory system cells
Authors: Zapór Lidia 
Published: October 2016

Abstract
Silver nanoparticles (AgNPs) are widely used in numerous industries and areas of daily life, mainly as antimicrobial agents. The particles size is very important, but still not suffi ciently recognized parameter infl uencing the toxicity of nanosilver. The aim of this study was to investigate the cytotoxic effects of AgNPs with different particle size (~ 10, 40 and 100 nm). The study was conducted on both reproductive and pulmonary cells (CHO-9, 15P-1 and RAW264.7). We tested the effects of AgNPs on cell viability, cell membrane integrity, mitochondrial metabolic activity, lipid peroxidation, total oxidative and antioxidative status of cells and oxidative DNA damage. All kinds of AgNPs showed strong cytotoxic activity at low concentrations (2÷13 μg/ml), and caused an overproduction of reactive oxygen species (ROS) at concentrations lower than cytotoxic ones. The ROS being formed in the cells induced oxidative damage of DNA in alkaline comet assay. The most toxic was AgNPs<10 nm. The results indicate that the silver nanoparticles, especially less than 10 nm, may be harmful to the organisms. Therefore, risk should be considered when using nanosilver preparations and provide appropriate protective measures when they are applied.
Treatment of wastewater from service areas at motorways
Authors: Makowska Małgorzata , Mazurkiewicz Jakub 
Published: October 2016

Abstract
This paper deals with wastewater treatment systems placed in motorway service areas (MSAs). In the years 2008-2009 eight of such facilities installed on the stretch of the A2 motorway between Poznań and Nowy Tomyśl were examined and analyzed. The system consists of a septic tank, a submerged aerated biofilter and an outflow filter. The volume of traffic on the highway was analyzed, the amount of water use was measured and peak factors were calculated. On this basis it was concluded that the inflows to the wastewater treatment systems in many cases exceeded the nominal design values.
Based on the analysis of effluent quality it was found that the effects of plant operation in large part did not meet the requirements. It was found that the bioreactor aeration system and the design of the suspension separator (outflow filter) should be modified. One of the solutions was to use the soil-reed bed for wastewater treatment. The treatment of wastewater from the MSAs is a task that must take into account the unusual character of these facilities and the atypical quality of the effluent.

Does Global English Support the Development of Social Europe?
Authors: Marácz László 
Published: October 2016

AbstractThe relevance of languages and multilingual communication for social policy and solidarity in the context of the nation-state has generally been recognized. However, in the context of Europeanization, this factor has been underestimated and neglected in scientific research. This paper argues that languages and multilingual communication are relevant for the design of Social Europe. In order to support this hypothesis, the paper relies on an analytical tool, the so-called floral figuration model proposed by De Swaan (1988). This model allows us to isolate social and linguistic actors and track down complex patterns of linguistic and communicative exclusion in Europe’s system of multilevel governance. These patterns also refer to international or global English or its technically adapted Brussels variety, ‘Euro-English’. From this, also follows that these patterns of linguistic and communicative exclusion must be rendered into inclusive ones before a European social policy can be realized.

Abstract
This paper presents solutions and the equipment for preheating combustion air from scrap aluminum melting furnaces through flue gas heat recovery. For sizing convection pre-heaters, there has been developed a mathematical model which has been transcribed into a computer program in C + +. A constructive version of the pre-heater was drawn up and a recovery heat exchanger was manufactured and mounted on an aluminum melting furnace. Both the functional parameters values and the reasons causing the pre-heater worning out, as well as the steps taken for sizing and the achievement of a new air pre-heater able to bear the operating conditions of the aluminum melting furnace are shown.
Determining the Heat Regime in the Working of a Coupling with Sliding Motion
Authors: Petre Ivona , Stoian Elena Valentina , Enescu Maria Cristiana 
Published: October 2016

Abstract
Following the sliding motion between two surfaces a heat release occures which leads to a changing of the mechanical properties of the surfaces in contact. Amongst the factors that influence the heat release one may name the loading, the velocity, the surface topography, the surface material, the lubrication and last but not the least, the environment.
The present paper proposes a computation model to determine the temperature in the working of a coupling to which the mechanical characteristics of the materials are not affected by changes which, at their turn, lead to undesired effects.
Cognitive Linguistics’ seven deadly sins
Authors: Dąbrowska Ewa 
Published: October 2016

AbstractCognitive Linguistics is an approach to language study based on three central premises: that the function of language is to convey meaning, that linguistic description must rely on constructs that are psychologically real, and that grammar emerges from usage. Over the last 40 years, this approach to studying language has made enormous strides in virtually every aspect of linguistic inquiry, achieving major insights as well as bringing about a conceptual unification of the language sciences. However, it has also faced problems, which, I argue, must be addressed if the approach is to continue to flourish. Some of these are shared with generative linguistics, while some are peculiar to the cognitive approach. The former include excessive reliance on introspective evidence; paying only lip service to the Cognitive Commitment; too much focus on hypothesis formulation (and not enough on hypothesis testing); ignoring individual differences; and neglecting the social aspects of language. The latter include assuming that we can deduce mental representations from patterns of use and equating distribution with meaning. I conclude by sketching out how these pitfalls could be avoided.
