Intertidal macrozoobenthos in sandy beaches of Bahía Nueva (Patagonia, Argentina) and their use as bioindicators of environmental impact

Macrozoobenthos were collected from urban sandy beaches of Puerto Madryn and adjacent areas in November 2005. Multivariate analysis techniques (ANOVA, nMDS, ANOSIM, SIMPER and RDA) were used to characterize the area based on the relationships among biological and environmental variables. The areas affected by outfall of fishery factories and pluvial effluent were defined as “perturbed zones” due to the dominance of the pollution indicator polychaetes Boccardia polybranchia and Capitella “capitata” sp. , which are associated with high values of ammonium, phosphates and organic matter. However, sandy beaches located 15 km from the city were considered as “unperturbed zones” because Psammodrilidae and Puelche orensanzi dominated, and they had high values of nitrates and dissolved oxygen. These taxa seem to be good candidates as indicators of clean zones for further studies. This is the first record of the family Psammodrilidae in the South Atlantic.
Affirmative Meritocracy

We argue that in important circumstances meritocracy can be realized only through a specific form of affirmative action we call affirmative meritocracy. These circumstances arise because common measures of academic performance systematically underestimate the intellectual ability and potential of members of negatively stereotyped groups (e.g., non-Asian ethnic minorities, women in quantitative fields). This bias results not from the content of performance measures but from common contexts in which performance measures are assessed—from psychological threats like stereotype threat that are pervasive in academic settings, and which undermine the performance of people from negatively stereotyped groups. To overcome this bias, school and work settings should be changed to reduce stereotype threat. In such environments, admitting or hiring more members of devalued groups would promote meritocracy, diversity, and organizational performance. Evidence for this bias, its causes, magnitude, remedies, and implications for social policy and for law are discussed.
Inverse Spectral Problem for the Periodic Camassa-Holm Equation

Abstract We consider the direct/inverse spectral problem for the periodic Camassa-Holm equation. In fact, we survey the direct/inverse spectral problem for the periodic weighted operator acting in the space L 2(ℝ, m(x)dx), where m = uxx −u > 0 is a 1-periodic positive function and u is the solution of the Camassa-Holm equation ut − uxxt + 3uux = 2uxuxx + uuxxx . For the operator L we describe the complete solution of the inverse spectral problem: i) uniqueness, prove that the spectral data uniquely determines the potential, ii) characterization, give conditions for some data to be the spectral data of some potential, iii) reconstruction, give an algorithm for recovering the potential from the spectral data, iv) a priori estimates, obtain two-sided a priori estimates of u, m in terms of gap lengths.
Irregular Function Estimation with LR-MKR

Estimating the irregular function with multi-scale structure is a hard problem. The results achieved by the traditional kernel learning are often unsatisfactory, since underfitting and overfitting cannot be simultaneously avoided, and the performance relative to boundary is often unsatisfactory. In this paper, we investigate the data-based local reweighted regression model under kernel trick and propose an iterative method to solve the kernel regression problem, local reweighted multiple kernel regression (LRMKR). The new framework of kernel learning approach includes two parts. First, an improved Nadaraya-Watson estimator based on blockwised approach is constructed to organize a data-driven localized reweighted criteria; Second, an iterative kernel learning method is introduced in a series decreased active set. Experiments on simulated and real data sets demonstrate the proposed method can avoid under fitting and over fitting simultaneously and improve the performance relative to the boundary effetely.
Alteration of iron stores in women of reproductive age with HIV in Abidjan (Côte D’ivoire)

The aim of this study is to evaluate and to characterize the iron metabolism in women of reproductive age infected by VIH in Abidjan. In order to review the iron stores in women of reproductive age, 180 women were recruited in a specialized center for treatment of HIV (ICBRA) based on the criteria for inclusion and exclusion. The mean age of women was 34.7 ± 0.5 years with extremes of 18 and 45 years. These women were classified into two groups of subjects namely 120 HIV positive women and 60 HIV negative as control women. Blood samples were taken from each of the selected women. Assays of various biological indicators (haematological and biochemical parameters) assessment of iron status were performed by different kits adequate for the automatic COBAS INTEGRA 400 Plus. The results of our investigations have demonstrated that all the searched biological has been degraded in enrolled women. Indeed our study found that for all subjects 79.4 % of women reported an abnormal iron status namely 71.7 % and 83.3 % respectively in control women and women with HIV. Abnormal iron status consisted of iron deficiency, iron deficiency anaemia, inflammatory anaemia and inflammatory anaemia associated with iron deficiency. Among the observed various components of iron status, inflammatory anaemia revealed the high prevalence rates in both groups of subjects (46.7 % vs 67.5 %). Our findings have then indicated that HIV infection has dramatically altered iron stores in women of reproductive especially those living with HIV/AIDS.

Animal Studies Repository 2012 A Queer Vegan Manifesto

What does it mean for a person to declare her or his veganism to the world? How does the transition from one diet to another impact one’s sense of self? Veganism challenges the foundational character of how we “act out” our selves—not least of all in the context of sexuality and gender. In my paper, I am thus interested in the potential of veganism to disrupt the “natural” bond between gender formations and the consumption of animal products, as this relates to social and cultural genealogies. Consequently, I will explore a queer form of veganism that affirms the radical impact of what Sara Ahmed calls “shared deviation. ”

Order tracking using H∞ estimator and polynomial approximation

This paper presents the H ∞ estimator for discrete-time varying linear system combined with the polynomial approximation for order tracking of non-stationary signals. The proposed approach is applied to the gearbox diagnosis under variable speed condition. In this instance, it is well known that the occurrence of a fault on a gear tooth leads to an amplitude and a phase modulation in the vibration signal. The purpose is to estimate this unknown amplitude and phase modulation by tracking orders. To estimate these modulations, the vibration signal is described in state space model. Then, the H ∞ criterion is used to minimize the worst possible amplification of the estimation error related to both the process and the measurement noises. Such an approach doesn't require any assumption on the statistic properties of the noises unlike the Kalman estimator. A numerical example is given in order to evaluate the performance of the H ∞ estimator regarding the conventional Kalman estimator.
Dealing with existential themes in acceptance and commitment therapy : a qualitative interview study

The present paper firstly reviews the relevance of death anxiety and meaning in life for psychotherapy, and their place in Existential Therapies, as well as Acceptance and Commitment Therapy (ACT). Secondly, a following qualitative interview study explores how ACT therapists deal with these themes in therapy practice. Nearly all ACT therapists were familiar with clients who struggle with death anxiety and a lack of meaning in life. A range of strategies were found, which can be subsumed under seven thematic categories. There was disagreement among the respondents on whether one should explore the client’s worldview and meaning-making regarding death anxiety and meaning in life, as this possibly contradicts with Relational Frame Theory (RFT), the philosophical foundation of ACT. Finally, this study gives first indications that ACT is a suitable form of therapy to help clients who struggle with existential themes.
Are social entrepreneurs lead users? : the first scale toretrospectively analyze whether social entrepreneursare lead users.

Innovations developed by users are ubiquitous nowadays. In previous studies, it has been found that successful and commercially attractive user innovations are developed by so called lead users that have been triggered by personal unmet needs to innovate. Lead users are characterized as being ahead of a trend and they expect to benefit from their innovations. What the present paper conducts is proposing a scale that can measure whether lead users have been triggered by personal unmet needs to innovate and develop commercially attractive social innovations. In other words, the present paper proposes a scale that is in a position to retrospectively measure whether social entrepreneurs are lead users. By examining whether social entrepreneurs are lead users, new insights into the antecedents of social entrepreneurship might be provided and a new avenue that lead users take when they decide to commercialize user innovations might be revealed. Existing scales that aim to determine lead users among user populations have been modified to come up with the proposed scale. The proposed scale finds its origins in Lepoutre, Justo, Terjesen, & Bosma (2013) to identify social entrepreneurs, in Luehtje, Herstatt, & von Hippel (2005) to differentiate between user innovators and non-user innovators, in Franke, von Hippel, & Schreier (2006) to assess the ‘expected benefit’ component and in Franke & Shah (2003) and Vernette, Bej-Becheur, Gollety, & Hamdi-Kidar (2014) to assess the ‘ahead of a trend’ component of the lead user definition. It needs to be noted that the present paper solely modifies existing scales and proposes a scale that meets this research’s objective and does not conduct any statistical measurements that verifies the reliability and validity of the proposed scale or draws any generalizations from the findings.
Exercise for falls management: Rationale for an exercise programme aimed at reducing postural instability

It is evident in the scientific and health promotion literature that interest in methods of reducing the risk factors associated with falls, in falls themselves, and in fall-induced injuries is increasing. However, the scientific evidence supporting the role exercise has to play in the management of elderly people who fall is inconsistent and, therefore, confusing. There have been calls for further research evidence, models of practice, guidelines on prevention, and treatment initiatives. Strategically, current guidelines are helpful but more detail is needed in order to assist practitioners to design effective exercise programmes for this vulnerable group. This paper provides a rationale for a specific, tailored, progressive programme of exercise. The programme not only incorporates all the basic fitness components seen in any well-run seniors' exercise class, but also includes specific falls management strategies, such as bone loading, gait, dynamic posture, balance, reaction and co-ordination training,.
UNDERSTANDING THE NATURE OF DEEP IMPRESSIONS BY ANALYZING THE STRUCTURE OF VIRTUAL IMPRESSION NETWORKS

We focus on deep impressions, which defined as the impressions that are related to the deep feelings towards a product and lie under the surface impressions. We aim at understanding the nature of preference that an individual may have with regard to a product. For that purpose, we developed a method for constructing ‘virtual impression networks’ and analyzed the structure. As the result, the difference appeared between the structural characteristics of ‘like’ and ‘dislike’ networks. We suggest that the understanding of the deep impressions may be the clue in understanding human preference.
Application of Full Wave Location technology with determining seismic moment tensor of events for Hydraulic Fracture Monitoring and Natural Fractures

especially important. Microseismic monitoring allows continuous monitoring of subsurface state and controlling of physical processes which generate elastic waves, in particular the process of hydraulic fracturing (Rutledge 1998; Urbancic 1999; Urbancic and Maxwell 2002; Shapiro 2015). This paper about a Full Wave Location (FWL) technology [1] that allows solving an event location problem with determination of its seismic moment, using maximum likelihood method, full wave numerical simulation and optimized survey design. The FWL technology has high noise immunity to correlated surface noises and allows determining orientation of each fracture.
MODIFIED PHASING ELEMENT FOR BROADBAND REFLECTARRAY ANTENNAS

New phasing element for a wideband microstrip reflectarray is presented. It is formed by a phase-delay line attached to a circular ring loaded with a circular disc microstrip. The structure is enclosed by a circular ring element with a pair of gaps. It is shown that the new phasing element offers a wider bandwidth with an increased phasing range that is useful in reflectarrays phase compensation procedure. Full wave EM simulations are carried out. Good agreement exists between simulation results and measurements by using waveguide simulator method. The mutual coupling effect for a realistic reflectarray configuration with non-identical cells is accounted for by using the perturbation technique.
Management of injected nitrogen into a gas condensate reservoir

This study investigates the means of deferring the breakthrough of injected N2 and alleviating the impact of such on production rates and specifications as well as minimizing the required changes to the gas processing facilities. This aimed at assisting the ongoing efforts to transfer the Cantarell experience to Abu Dhabi, where large amounts of N2 gas will be generated and injected into a large gas condensate reservoir to partially substitute the recycling of lean gas. This will bring forward the opportunity to exploit lean gas by securing base load supplies before the start of reservoir blowdown, compared to the peak shaving approach currently practiced. Managing N2 breakthrough starts by better understanding the pattern at which N2 injection spreads into the gas accumulation. Based on the findings of initial subsurface and plant simulations carried out in 2008, N2 breakthrough in Abu Dhabi might be possibly deferred by segmenting the reservoir into a rich N2 region and lean N2 region. The approach assumes no thief zones will be faced and no channeling of N2 injected between the two regions is taking place. N2 is injected in the north region of the reservoir. The production of that region will be segregated and fed to a gas processing plant of lower NGL (natural gas liquid) recovery, which essentially takes longer time to start suffering the deterioration of residue gas (gas mixture resulted after separating NGL) quality. The residue gas use can be limited to re-injection where the effect of below specification LHV (Low Heat Value) would not be an issue. The rest of the reservoir feeds another gas processing plant of higher NGL recovery level from which an amount of residue gas equivalent to that of the injected N2 will be rerouted to the sales network. This scenario will significantly delay as well as downsize the requirement of a N2 rejection plant. There is technical and certainly economical advantage of deferring the installation of costly N2 rejection units. Such a requirement can be entirely eliminated if the sales gas specification can be relaxed considering blending with other gas streams of higher LHV, and in collaboration with gas customers, i.e. assessing their capability to tolerate feedstock of lower specifications. It must be noted that such school of thinking may not necessarily be eventually embraced. The chosen scenario will also depend on the final configuration, i.e., wells grouping and gas gathering, of the ongoing project.
Water flow in Carbon and Silicon Carbide nanotubes

In this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. In order that studies on different types of nanotubes be comparable, the chiral vectors of C and Si-C nanotubes are selected as (7,7) and (5,5), respectively, so that a similar volume of fluid is investigated flowing through two similar dimension membranes. Different hydrostatic pressures are applied and the flow rates of water and ions are calculated through molecular dynamics simulations. Consequently, according to conductance of water per each nanotube, per nanosecond, it is perceived that at lower pressures (below 150 MPa) the Si-C nanotubes seem to be more applicable, while higher hydrostatic pressures make carbon nanotube membranes more suitable for water desalination.
Precipitation of Carbonates Crystals by Bacteria Isolated from a Submerged fixed-film Bioreactor used for the Treatment of urban Wastewater

The precipitation of calcium carbonate by bacteria isolated from submerged fixed-film bioreactorused for the treatment of urban wastewater in both natural and artificial media was studied. However, carbonate precipitation was detected only when the bacteria grow in media added with calcium. Precipitation took place rapidly, and crystal formation began 3 d after inoculation and the percentage of carbonate-forming bacteria was slightly higher than 90%. Seventeen dominant colonies with carbonate precipitation capacity were the dominant heterotrophic platable bacteria growing aerobically in media added with calcium acetate and calcium chloride. According to their taxonomic affiliations (based on partial sequencing of the 16S-rRNA), the seventeen strains belonged to the following genera of Gram-positive and Gram-negative bacteria: Artrobacter, Bacillus, Enterococcus, Pseudomonas, Agromyces and Rhodococcus. All of these strains formed calcium carbonate crystals, precipitated always as calcite crystals which showed large amounts of bacterial fingerprints or bacteria calcification. In addition all the seventeen bacterial strains showed carbonic anhydrase activity. The results of this research suggest that in submerged fixed-film bioreactors used for the treatment of urban wastewater, the precipitation of carbonates through bacterial action could take place in situ in the presence of certain concentrations of calcium. Moreover, this biological activity could be useful in the CO2 and calcium capture in urban wastewater treatments.
