PREDICTION OF TROPOSPHERIC OZONE AT RIO DE JANEIRO CITY FROM PRIMARY POLLUENTS AND METEOROLOGICAL FACTORS USING ARTIFICIAL NEURAL NETWORKS (ANN) AND SUPPORT VECTOR MACHINE (SVM) REGRESSION

Tropospheric ozone is well known as an extremely important factor due to its strong environmental impact. The air quality depends on emissions, meteorology and topography. NO2, NO, NOx, CO, O3, scalar wind speed, solar radiation, temperature, and relative humidity (HUM) were monitored. These data sets were collected by the mobile station monitoring located at PUC-Rio and UERJ between 2011 and 2012, from the Secretary of the Environment of Rio de Janeiro. This study aimed at the prediction of O3 from primary pollutants and meteorological factors. The obtained results of ANN and SVM regression techniques were acceptable to the dataset UERJ presenting coefficient of determination (R 2 ) for validation, 0.9122 and 0.9152, and the square root of the mean square error of cross validation (RMECV) 7.66 and 7.85, respectively. Regarding the data set of PUC-Rio, the two techniques gave inferior results.
HALO AND PSEUDOHALO-DEMETALLATION IN TETRA AND PENTA- ORGANOMETAL AND METALLOIDS

Halo and pseudohalo demetallation reactions of higher valent pentaphenyl –arsenic and antimony and, tetrapolyfluorophenyl tin have been carried out employing halogens X2 (X = Br, I) interhalogens IX (X = Cl, Br), ICl3, pseudohalogen (SCN)2, halo-pseudohalogens XSCN (X = Cl, Br) IN3, INCO and, metallic halides TeCl4 and (NH4)2PbCl6. Reaction of (C6H5)5M (M= As,Sb) with these electrophiles afforded corresponding arsonium and stibonium derivatives (C6H5)4MX while reactions of tetrafluorophenyl tin (C6F5)4Sn with halogens and interhalogens yielded corresponding (C6F5)nSnX4-n (X = Cl, Br n = 2,3) derivatives depending upon the molar ratio of reactants and the reaction conditions. The products have been identified by m.p. elemental analysis and spectroscopic data.
Full Proof Secured Environment for Wireless Sensor Networks

– Due to the technological innovations of sensor technologies, Wireless Sensor Networks (WSNs) have become very popular with its applications being used in many domains. The applications include those pertaining to civilian and military especially for monitoring environments. Out of all the interesting applications which are based on WSN, there are sensitive applications that need total security. This has to be understood from the standpoint that WSN lifetime is less due to resource constraints and controlling them personally is not feasible. This paper presents a new protocol that addresses some of the security threats prevailing in the arena of WSNs. We present a scheme and a protocol to prevent attacks such as distributed sensor cloning attack, man – in the middle attack and replay attack. Our scheme verifies the authenticity of wireless sensor nodes to prevent cloning attack by using fingerprint concept associated with each and every sensor. The proposed protocol ensures that the sensitive data pertaining to cryptographic methods is not transmitted across network and prevents attacks such as replay attack and man – in – the middle attack. The empirical results through simulations revealed that the proposed scheme and protocol can prevent the three security threats in WSNs successfully.
Action dimensions of some simple complexes of groups

The action dimension of a discrete group G is the minimum dimension of a contractible manifold that admits a proper G ‐action. We compute the action dimension of the direct limit of a simple complex of groups for several classes of examples including (1) Artin groups, (2) graph products of groups and (3) fundamental groups of aspherical complements of arrangements of affine hyperplanes.
Lawrence Berkeley National Laboratory Lawrence Berkeley National Laboratory Title Estimation of composite thermal conductivity of a heterogeneous methane hydrate sample using iTOUGH 2 Permalink

We determined the composite thermal conductivity (kθ) of a porous methane hydrate sample (composed of hydrate, water, and methane gas) as a function of density using iTOUGH2. X-ray computed tomography (CT) was used to visualize and quantify the density changes that occurred during hydrate formation from granular ice. The composite thermal conductivity was estimated and validated by minimizing the differences between the observed and the predicted thermal response using history matching. The estimated density-dependent composite thermal conductivity ranged between 0.25 and 0.58 W/m/K.
Overcoming disadvantage, achieving success: What helps

The Bradley Review of Australian Higher Education (2008) and subsequent government policies have led to increased participation in higher education of underrepresented or equity groups, “those disadvantaged by the circumstance of their birth” (p. xi). However, despite institutional interventions, disparity in retention and completion rates continues for these groups (Lim, 2015; Edwards & McMillan, 2015). Although objective measures allow institutions to report on inclusion targets, a focus on the student experience of disadvantaged groups is critical for the development of appropriate institutional support. This study used a mixed methods approach to survey successful students’ experiences of challenge or disadvantage while studying, their identification with equity groups and, importantly, their experience of success. The sample comprised 308 students who had sought help to develop their academic skills, a crucial area for success for all students but particularly disadvantaged students (McKay & Devlin, 2014). Findings confirmed that the majority had overcome some level of disadvantage, with the main types identified as, balancing commitments, health issues and financial stress. Although these align with factors identified by consecutive University/Student Experience Surveys (2013; 2014; 2015) as the most common reasons for withdrawal, our student sample overcame these challenges to achieve success. Discipline teaching staff and central support services, particularly academic language and learning, are the most common helpful factors and central support is increasingly important at greater levels of disadvantage. Our findings align with proposals for institutional provision for joint initiatives by teaching staff and central support services to address student disadvantage and enable success.
Pre-hCG variables associated with occurrence of ascites in IVF/ICSI patients at moderate risk of developing OHSS: A pilot investigation

Objective: To identify predictors of ascites collected prior to the hCG administration in patients undergoing IVF/ICSI treatment at moderate risk of developing moderate/severe ovarian hyperstimulation syndrome (OHSS), and, based on these predictors, develop a nomogram for estimation of the probability of presence of ascites. Methods and Materials: Data were derived from 53 patients with 20 - 30 follicles ≥10 mmat end of stimulation. All patients received a single dose of hCG (250 mg) to trigger final follicular maturation when ≥2 follicles of ≥18 mmwere observed. Transvaginal ultrasound to measure ascites (total amount of peritoneal fluid ≥9 cm2inlithotomy position) was performed 2, 5 and 8 days after the hCG administration. Associations between clinical, sonographic and endocrinological variables recorded prior to the hCG administration and presence of ascites were analyzed by univariable and multivariable logistic regression. Results: Thirty-four patients (64%) had ultrasonic evidence of ascites. The multivariable analysis identified the total number of follicles [OR 1.29 (95% CI: 1.02 - 1.69, P = 0.043)], the ovarian volume [OR 1.05 (95% CI: 1.00 - 1.11, P = 0.047)] and BMI [OR 0.76 (95% CI: 0.56 - 0.99, P = 0.053)] as predictors of ascites (AUC = 0.825). A nomogram (PROFET) was designed with these three variables for individual prediction of the probability of development of ascites. Conclusions: This pilot investigation indicates that the risk of peritoneal fluid accumulation in IVF/ICSI patients at moderate risk of developing moderate/severe OHSS is influenced by the number of follicles and the ovarian volume on the day of hCG administration as well as the BMI.
Coping with corruption in foreign markets

Executive Summary Government corruption is a pervasive element of the international business environment and has damaging effects on governments, firms, and the broader society in which it takes place. Recently publicized scandals in Russia, China, Pakistan, Lesotho, South Africa, Costa Rica, Egypt, and elsewhere underscore the extent of corruption globally, especially in the developing world. Yet, the impact of government corruption on foreign investment has received limited attention. In this article, we examine how multinational firms respond to corruption when investing in foreign markets, especially developing countries. The article begins with a discussion of the direct and indirect costs of corruption to business and provides illustrations of corruption's impact on firms that invest in foreign markets. We employ a framework that incorporates two basic dimensions of government corruption--pervasiveness and arbitrariness. We then propose five broad strategies that multinationals should consider in re.
MODERATING EFFECT OF ENTREPRENEURIAL ORIENTATION ON ENTREPRENEURIAL COMPETENCIES AND PERFORMANCE OF AGRO-BASED SMEs

The objective of this research was to examine the moderating effect of entrepreneurial orientation on the relationship between entrepreneurial competencies and performance of agro-based SMEs in Nigeria. The study used questionnaires gathered from 230 managers of agro-based firms in Lagos state Nigeria. Data analysis was carried out using hierarchical multiple regression to show relationships between the variables. Findings suggest that entrepreneurial competencies have a direct influence on performance of Agro-based SMEs. More so, the statistical result indicates that innovativeness, proactiveness and autonomy are the three entrepreneurial orientations that moderate the relationship between entrepreneurial competencies and performance of the firms.
Trophic modes of large Antarctic Foraminifera: roles of carnivory, omnivory, and detritivory

Astrammina rara, Crithionina delacai, and Notodendrodes hyalinosphaira are 3 of the largest and most abundant members of the foraminiferal assemblage at a shallow-water (28 to 32 m) site in Explorers Cove, Antarctica. This study summarizes observations from 2 decades of research, during which we employed laboratory-based feeding experiments and fatty acid biomarker analysis to characterize trophic dynamics and ecological roles of the 3 species. In feeding experiments, A. rara consumed a variety of co-occurring metazoans (several Crustacea, Mollusca, Echinodermata, and a Nephtys species). C. delacai, N. hyalinosphaira, and a number of other foraminiferal species from Explorers Cove successfully trapped Artemia sp. nauplius prey in a setup designed to examine the efficiency of prey capture. Fatty acid analyses on samples from early (November 7, 2001) and late (January 31, 2002) austral summer revealed that the 3 species contained substantial amounts (33 to 45.5%) of polyunsaturated fatty acids (PUFAs), which are produced by microalgae, indicating the downwards transfer of carbon from sea-ice associated primary production. In the case of A. rara, this may be due to the ingestion of herbivorous metazoa, rather than direct uptake of microalgal mater- ial. A. rara contained significantly (p < 0.05) higher amounts of the zooplankton biomarkers 20:1(n-9) and 22:1(n-11), and C. delacai contained more PUFAs early, compared to late, in the season. Two morphotypes of N. hyalinosphaira had different fatty acid profiles, indicating distinct trophotypes. Our results illustrate specific adaptations to different trophic resources in these protists, and they demonstrate the potential impact that large carnivorous species of Foraminifera may have on the structure of benthic communities where they are abundant.
Komarekiella atlantica gen. et sp. nov. (Nostocaceae, Cyanobacteria): a new subaerial taxon from the Atlantic Rainforest and Kauai, Hawaii

Six strains of Cyanobacteria sampled in the Brazilian Atlantic rainforest and one strain from Kauai, Hawaii, were studied using morphological and molecular approaches, including 16S rRNA gene phylogenies and 16S-23S ITS secondary structures, and are herein described as Komarekilla atlantica gen. et sp. nov. Morphologically they are similar to Nostoc, Desmonostoc, Halotia, and Mojavia and indistinguishable from Chlorogloeopsis. The parsimony and Bayesian phylogenies of the 16S rDNA show that these strains are close to nostocacean strains, in strongly supported clades and separated from all other genera. The secondary structures of the 16S-23S ITS were very consistent between strains of K. atlantica, but distinctly different from structures in other close taxa. Of special note, the Hawaiian strain of K. atlantica had 16S sequence identities of 99.5-100% to the Brazilian strains, and 16S-23S ITS sequence identities of 99.4-99.8% to the Brazilian strains, and consequently likely represents a very recent introduction of the species to Kauai from South America, the geographic source of many of the non-native plants in the Hawaiian Archipelago.
A Glimpse at the Ontogeny of the Fossil Neobatrachian Frog Calyptocephalella canqueli from the Deseadan (Oligocene) of Patagonia, Argentina

Two fossil tadpoles collected in the Deseadan levels (Oligocene) at the Scarritt Pocket locality of central Patagonia are studied herein. These specimens, which show different degrees of skeletal development, have been assigned to the neobatrachian Calyptocephalella canqueli based on the morphology of the frontoparietals and the presence of adult specimens of this fossil species at the same locality. The concurrent analysis of three developmental stages (Gosner Stages 35/36 and 38/39, and adult) has provided significant data about the ontogeny of this species, including the change of the pattern of exostosis of the frontoparietals, from a pitted to a tuberculated pattern, and the corroboration of the inclusion of two neural arches in the formation of the urostyle. This evidence will shed light on developmental mechanisms that might be involved in the evolution of the genus Callyptocephalella.
imited pollen flow and high selfing rates toward geographic range imit in an Atlantic forest bromeliad ecele

Bromeliaceae is a Neotropical family that evolved ecological key innovations in association with extensive adaptive radiation. Its species present a variety of different mating system strategies varying within and among species, within genera and subfamilies. Also, species with a wide geographical range can display large variation in mating system, reproductive success and genetic diversity. Here we combined data from hand pollinations and genetic analysis to assess outcomes of contemporary gene flow and mating system variation at the range edge of Vriesea gigantea. Results from pollen germination rates showed that this species is cryptically self-incompatible. Hand-pollination experiments and genetic analysis of progeny arrays revealed that V. gigantea has a mixed mating system, with high selfing rates (s = 0.612), and high inbreeding coefficient (F = 0.372). Inbreeding in V. gigantea at southern edge of its distribution
Biochemical changes in cotton plants due to infestation by cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae)

The study on biochemical changes in cotton plants (Gossypium hirsutum L.) due to infestation by cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) was conducted at CICR Nagpur during 2014-15. Total protein contents estimated from the shoots of the healthy plants (4.29 mg/g) indicated 50.5% increase over the healthy plants (2.85 mg/g). Total phenol content increased by 185.7% in the mealybug infested plants (0.20I¼g/g) over the healthy plants (0.07I¼g/g). Insignificant difference in the level of total soluble sugar was observed in mealybug infested plants (1.00I¼g/g) as compared to healthy plants (0.90I¼g/g). Total reducing sugar was found to be unaffected with the mealybug infestation. Although there was depletion in all the photosynthetic pigments viz., chlorophyll a (19.1%), chlorophyll b (23.7%), total chlorophyll (21.2%) and carotenoids (20.8%) due to the mealybug infestation, these values were not statistically different in the healthy plants. This is the first report on biochemical changes in cotton plant due to infestation of P. solenopsis.

OPTIMAL L 2 -ERROR ESTIMATES FOR EXPANDED MIXED FINITE ELEMENT METHODS OF SEMILINEAR SOBOLEV EQUATIONS

In this paper we derive a priori L ∞ (L 2 ) error estimates for expanded mixed finite element formulations of semilinear Sobolev equa- tions. This formulation expands the standard mixed formulation in the sense that three variables, the scalar unknown, the gradient and the flux are explicitly treated. Based on this method we construct finite ele- ment semidiscrete approximations and fully discrete approximations of the semilinear Sobolev equations. We prove the existence of semidiscrete approximations of u, −∇u and −∇u−∇ut and obtain the optimal order error estimates in the L∞(L2) norm. And also we construct the fully discrete approximations and analyze the optimal convergence of the ap- proximations in l ∞ (L 2 ) norm. Finally we also provide the computational results.
TOWARDS EFFICIENCY OF OBLIQUE IMAGES ORIENTATION

Many papers on both theoretical aspects of bundle adjustment of oblique images and new operators for detecting tie points on oblique images have been written. However, only a few achievements presented in the literature were practically implemented in commercial software. In consequence often aerial triangulation is performed either for nadir images obtained simultaneously with oblique photos or bundle adjustment for separate images captured in different directions. The aim of this study was to investigate how the orientation of oblique images can be carried out effectively in commercial software based on the structure from motion technology. The main objective of the research was to evaluate the impact of the orientation strategy on both duration of the process and accuracy of photogrammetric 3D products. Two, very popular software: Pix4D and Agisoft Photoscan were tested and two approaches for image blocks were considered. The first approach based only on oblique images collected in four directions and the second approach included nadir images. In this study, blocks for three test areas were analysed. Oblique images were collected with medium-format cameras in maltan cross configuration with registration of GNSS and INS data. As a reference both check points and digital surface models from airborne laser scanning were used.
Développement de l'organisation syntaxique du dessin chez l'enfant de 5 à 10 ans et l'adulte et sensibilité au contexte

L’etude du niveau syntaxique du dessin fait reference a la maniere dont le sujet organise la realisation des mouvements. Cette organisation peut etre decrite a un niveau local, concerne par la facon dont chaque segment est trace (regles d’action), ou a un niveau global, qui rend compte de l’ordre dans lequel les unites sont realisees (strategies graphiques). L’objectif principal de ce travail est de determiner s’il existe des caracteristiques dans l’organisation syntaxique du dessin aux differents âges qui refletent un developpement de type sequentiel ou si une variabilite importante apparait dans les productions graphiques selon des manipulations de contexte. Pour cela, differentes tâches de copie de figures geometriques ont ete proposees a des enfants âges de 5 a 10 ans et a de adultes. Une premiere etude inique l’existence de trois etapes developpementales dans l’application des regles d’action selon la complexite des patterns. La deuxieme partie experimentale a etudie le developpement des strategies graphiques. Une experience realisee en situation de copie libre a mis en evidence l’existence de categories de strategies caracteristiques des differents âges. Quatre etudes d’amorcage et une etude proposant une tâche de completion de figure ont ete menees et revelent des modifications dans la relation âge / categories de strategies. Cependant, les enfants de 6 ans et les adultes ne modifient leur comportement graphique que si la tâche les y contraint. L’ensemble de nos resultats suggerent une integration necessaire des modeles postulant l’existence d’un developpement de type sequentiel et ceux mettant l’accent sur l’impact du contexte. Enfin, la derniere partie experimentale s’est interessee au dessin d’enfants presentant des troubles dyslexiques. Ces enfants respectent moins les regles d’action et presentent des difficultes de planification par rapport aux enfants normo-lecteurs de meme âge.
Human Reaction to Threat: Examining the Interplay Between Personality Dispositions and Situational Features

Objective: Research on human reaction to threats has been limited and focused either on the effects of situational features or on the effects of personality dispositions. In the present research, we examined the processes by which personality (specifically attachment orientations) qualifies the effects of situational features on reactions to threat scenarios. Method: In Study 1, 307 Israeli participants completed a self-report measure of attachment orientations (anxiety and avoidance), and reported on the first action that they are likely to take on various threat scenarios. In Study 2, 295 non-Israeli participants completed self-report measures of attachment orientations (anxiety and avoidance), fear of negative evaluation, and body sensations (the latter two served as covariates), and reported on their reactions to threat scenarios as in Study 1. Results: Results indicated that attachment anxiety qualified the effects of situational features to increase the likelihood of sentinel (e.g., yelling) and fear-related behaviors (e.g., running away). Avoidance qualified the effects of situational features to increase the likelihood of rapid-responder (e.g., attacking), fear-related, and anxiety-related (e.g., risk assessment) reactions. Conclusions: Results are discussed in relation to the complex interplay between personality and situational features on humans’ behaviors when dealing with threats and danger.
