GAMERA: A Three-dimensional Finite-volume MHD Solver for Non-orthogonal Curvilinear Geometries
Authors: Zhang Binzheng , Sorathia Kareem A. , Lyon John G. , Merkin Viacheslav G. , Garretson Jeffrey S. , Wiltberger Michael
Published: September 2019

Efficient simulation of plasmas in various contexts often involves the use of meshes that conform to the intrinsic geometry of the system under consideration. We present here a description of a new magnetohydrodynamic code, GAMERA (Grid Agnostic MHD for Extended Research Applications), designed to combine geometric flexibility with high-order spatial reconstruction and constrained transport to maintain the divergence-free magnetic field. GAMERA carries on the legacy of its predecessor, the LFM (Lyon–Fedder–Mobarry), a research code whose use in space physics has spanned three decades. At the time of its initial development, the LFM code had a number of novel features: eighth-order centered spatial differencing, the Partial Donor Cell Method limiter for shock capturing, a non-orthogonal staggered mesh with constrained transport, and conservative averaging-reconstruction for axis singularities. The capability to handle multiple ion species was also added later. GAMERA preserves the core numerical philosophy of LFM while also incorporating numerous algorithmic and computational improvements. The upgrades in the numerical schemes include accurate grid metric calculations using high-order Gaussian quadrature techniques, high-order upwind reconstruction, non-clipping options for interface values, and improved treatment of axis singularities. The improvements in the code implementation include the use of data structures and memory access patterns conducive to aligned vector operations and the implementation of hybrid parallelism, using MPI and OMP. GAMERA is designed to be a portable and easy-to-use code that implements multidimensional MHD simulations in arbitrary non-orthogonal curvilinear geometries on modern supercomputer architectures.

We investigate the effects of extended multiyear light curves (9 yr photometry and 5 yr spectroscopy) on the detection of time lags between the continuum variability and broad-line response of quasars at z ≳ 1.5, and compare with the results using 4 yr photometry+spectroscopy presented in a companion paper. We demonstrate the benefits of the extended light curves in three cases: (1) lags that are too long to be detected by the shorter-duration data but can be detected with the extended data; (2) lags that are recovered by the extended light curves but are missed in the shorter-duration data due to insufficient light-curve quality; and (3) lags for different broad-line species in the same object. These examples demonstrate the importance of long-term monitoring for reverberation mapping to detect lags for luminous quasars at high redshift, and the expected performance of the final data set from the Sloan Digital Sky Survey Reverberation Mapping project that will have 11 yr photometric and 7 yr spectroscopic baselines.

Published: September 2019

Recent active galactic nucleus (AGN) and quasar surveys have revealed a population showing rapid AGN luminosity variability by a factor of ∼10. Here we present the most drastic AGN luminosity decline by a factor of ≳103 constrained by a NuSTAR X-ray observation of the nearby galaxy Arp 187, which is a promising “dead” quasar whose current activity seems quiet but whose past activity of

erg s−1 is still observable at a large scale by its light echo. The obtained upper bound of the X-ray luminosity is

, corresponding to

, indicating an inactive central engine. Even if a putative torus model with

cm−2 is assumed, the strong upper bound still holds with

or

. Given the expected size of the narrow-line region, this luminosity decrease by a factor of ≳103 must have occurred within ≲104 yr. This extremely rapid luminosity/accretion shutdown is puzzling, and it requires one burst-like accretion mechanism producing a clear outer boundary for an accretion disk. We raise two possible scenarios realizing such an accretion mechanism: a mass accretion (1) by the tidal disruption of a molecular cloud and/or (2) by the gas depletion as a result of vigorous nuclear star formation after rapid mass inflow to the central engine.

First record of Amphoromorpha/ Basidiobolus fungus on centipedes (Geophilomorpha, Geophilidae) from Brazilian caves
Authors: Pacheco Fonseca Régia Mayane , de Paula Caio César Pires , Bichuette Maria Elina , Chagas Jr Amazonas
Published: September 2019

We identified Basidiobolus fungi on geophilomorphan centipedes (Chilopoda) from caves of Southeast Brazil. Twelve specimens of centipedes of the family Geophilidae were examined, and two of them carried the secondary capilliconidia of Basidiobolus on their exoskeleton. The fungus uses the surface of the exoskeleton as a support for the asexual reproductive structure. In this manner, the host is used for the purpose of dispersing its spores. This study expands current knowledge of the diversity of arthropods used as host for the fungus, and in particular for Basidiobolus, living in cave habitats.

Existe-t-il une architecture totalitaire ?
Authors: de Mijolla-Mellor Sophie , Tuncel Gökçe
Published: September 2019

Comment l’architecture est-elle mobilisée par les régimes dits « totalitaires » ? Afin de répondre à cette question, cet article abordera essentiellement l’architecture sous le régime Nazi avec une comparaison sous Staline et enfin sous Mussolini. Dans chacun de ces cas, nous chercherons à dégager le rôle de l’architecture au sein de la mobilisation et/ou de la consolidation du pouvoir : quelle fonction est attribuée à l’architecture dans ces régimes et pour quelles raisons ? Et peut-on parler d’une architecture qui portera des éléments stylistiques qu’on pourrait définir en tant que « totalitaires » ?
De la barbarie, de l’impuissant pouvoir de l’art, de la performativité quand même
Authors: Ardeven François
Published: September 2019

L’art et le pouvoir ont tous les deux à voir avec la représentation. Le pouvoir s’est imposé assez vite à homo sapiens comme une technique par laquelle un grand nombre est représenté par un petit nombre — et parfois un seul. L’art a affaire autrement avec la représentation. Son enjeu semble souvent de représenter l’irreprésentable — le coït ou la mort — , et s’il y un pouvoir de l’art, il tient aussi paradoxalement dans son impuissance On prendra d’abord comme exemple l’avant-garde russe où pouvoir et art semblent danser ensemble et ensuite le fameux « verdict », comme dit Youssef Ishaghpour, de Theodor Adorno : « Ecrire un poème après Auschwitz est barbare ». Adorno semble retirer à l’art son pouvoir civilisateur. Le poète Paul Celan, dans un entretien intellectuel continu avec Adorno qu’il admirait aussi, ne l’entendait pas ainsi.
Les représentations du beau et du laid dans la construction du jugement esthétique
Authors: Cernat Cristina
Published: September 2019

Si le beau et le laid n’existent pas en tant que tels dans la logique inconsciente, c’est parce qu’ils se représentent par rapport à une signification phallique. Le pouvoir de l’ambivalence psychique dans laquelle plongent les représentations châtré/phallique joue un rôle fondamental dans la construction du jugement esthétique. En effet, l’expérience esthétique naît des représentations sociales et inconscientes, dont nous nous proposons d’analyser le rôle dans la nécessité d’une maîtrise esthétique.
La « Reconquista » et les paysages des hautes terres éthiopiennes
Authors: Gascon Alain
Published: September 2019

Durant son règne (1889-1913), Menelik II repoussa les Italiens et les frontières de l’Éthiopie pour englober un glacis de basses terres et rattacher les hautes terres méridionales. Conquête coloniale ou « Reconquista » de territoires perdus aux XVIe et XVIIe siècles ? Le débat, récurrent, n’est pas clos. Cette expansion, sans transfert massifde population, entraîna l’avancée de la céréaliculture à l'araire, vers le Sud, et donc l'extension des openfields. Dans les nouvelles possessions, les chef militaires établirent un maillage de villes nouvelles, fortes, les kätäma, dans le but de collecter le tribut et le produit du travail des vaincus. Bâties selon le plan et l’architecture d’Addis Abäba, fondée par Menelik, en 1889, elles ne connurent pas toutes le succès de la kätäma capitale. Elles sont à l'origine du réseau urbain actuel de l’Éthiopie méridionale. La Reconquista signifia bien plus la transformation des systèmes et des paysages agraires, les débuts de l’urbanisation, qu’un bouleversement du peuplement de la Grande Éthiopie.

A Generalized Parallel Quantum Inspired Evolutionary Algorithm Framework for Hard Subset Selection Problems
Authors: Bansal Sulabh , Patvardhan C.
Published: September 2019

Quantum-inspired evolutionary algorithms (QIEAs) like all evolutionary algorithms (EAs) perform well on many problems but cannot perform equally better than random for all problems due to the No Free Lunch theorem. However, a framework providing near-optimal solutions on reasonably hard instances of a large variety of problems is feasible. It has an effective general strategy for easy incorporation of domain information along with effective control on the randomness in the search process to balance the exploration and exploitation. Moreover, its effective parallel implementation is desired in the current age. Such a Generalized Parallel QIEA framework designed for the solution of Subset Selection Problems is presented here. The computational performance results demonstrate its effectiveness in the solution of different large-sized hard SSPs like the Difficult Knapsack Problem, the Quadratic Knapsack Problem and the Multiple Knapsack problem. This is the first such a generalized framework and is a major step towards creating an adaptive search framework for combinatorial optimization problems.

Authors: Afolabi Ibukun Tolulope , Makinde Opeyemi Samuel , Oladipupo Olufunke Oyejoke
Published: September 2019

Currently, for content-based recommendations, semantic analysis of text from webpages seems to be a major problem. In this research, we present a semantic web content mining approach for recommender systems in online shopping. The methodology is based on two major phases. The first phase is the semantic preprocessing of textual data using the combination of a developed ontology and an existing ontology. The second phase uses the Naïve Bayes algorithm to make the recommendations. The output of the system is evaluated using precision, recall and f-measure. The results from the system showed that the semantic preprocessing improved the recommendation accuracy of the recommender system by 5.2% over the existing approach. Also, the developed system is able to provide a platform for content-based recommendation in online shopping. This system has an edge over the existing recommender approaches because it is able to analyze the textual contents of users feedback on a product in order to provide the necessary product recommendation.

Published: September 2019

Water management has always been a topic of serious discussion since infrastructure, rural, and industrial development flourished. Due to the depleting water resources, this is now even a bigger challenge. So, here is developed an IoT-based water management system where ultrasonic sensors are employed for predicting the depth of water in the tank and accordingly pumping the water to the sub tank of the apartment. In addition, the time series analysis Auto Regressive Integrative Moving Average (ARIMA) and Least Square Linear Regression (LSLR) algorithms were employed and compared for predicting the water demand for next six months based on the historical water consumption record of the main reservoir/tank. The information on the amount of water consumed from the main reservoir is pushed to the cloud and to the mobile application developed for utilities. The purpose is to access the water consumption pattern and predict water demand for the next six months from the cloud.
DistProv-Data Provenance in Distributed Cloud for Secure Transfer of Digital Assets with Ethereum Blockchain using ZKP
Authors: Gouru Navya , Vadlamani NagaLakshmi
Published: September 2019

The importance and usage of the distributed cloud is increasing rapidly over a traditionally centralized cloud for the storing and exchanging of digital assets between untrusted parties in many business sectors. Storing the digital assets in the distributed cloud is considered superior to traditional cloud computing in terms of environmentally friendly, cost, security and other technical dimensions. In this article, a contemporary architecture DistProv is proposed where an open source distributed cloud IPFS is used to store and transfer the digital assets between the consignor and consignee. These two are untrusted parties exchanging sensitive documents secured by cryptographic algorithms with permission-based access verified by ethereum smart contracts using zero-knowledge proof (ZKP) and simultaneously publishing the provenance data about the digital asset as a transaction on the blockchain. This article also discusses on verifying the integrity of the digital assets and authentication of the consignor and thus preserving a strong CIA triad.
Optimization Driven Constraints Handling in Combinatorial Interaction Testing
Authors: Gouda Ram , Chandraprakash V.
Published: September 2019

The combinatorial strategy is useful in the reduction of the number of input parameters into a compact set of a system based on the combinations of the parameters. This strategy can be used in testing the behaviour that takes place when the events are allowed to be executed in an appropriate order. Basically, in the software systems, for the highly configurable system, the input configurations are based on the constraints, and the construction of this idea undergoes various kinds of difficulties. The proposed Jaya-Bat optimization algorithm is developed with the combinatorial interaction test cases in an effective manner in the presence of the constraints. The proposed Jaya-Bat based optimization algorithm is the integration of the Jaya optimization algorithm (JOA) and the Bat optimization algorithm (BA). The experimentation is carried out in terms of average size and the average time to prove the effectiveness of the proposed algorithm. From the results, it is clear that the proposed algorithm is capable of selecting the test cases optimally with better performance.

Objective of this study is to investigate the potential of an artificial intelligence (AI) technique, based on competitive learning, for the discrimination of benign from malignant endometrial nuclei and lesions. For this purpose, 416 liquid-based cytological smears with histological confirmation were collected, each smear corresponded to one patient. From each smear was extracted nuclear morphometric features by the application of an image analysis system. Subsequently nuclei measurement from 50% of the cases were used to train the AI system to classify each individual nucleus as benign or malignant. The remaining measurement, from the unused 50% of the cases, were used for AI system performance evaluation. Based on the results of nucleus classification the patients were discriminated as having benign or malignant disease by a secondary subsystem specifically trained for this purpose. Based on the results it was conclude that AI based computerized systems have the potential for the classification of both endometrial nuclei and lesions.
Third Age and Mobile Health
Authors: Pouliakis Abraham
Published: September 2019

It is well known that the earth population is aging; in the forthcoming decades, a so called “silver tsunami” is expected. By 2050 the forecasted population aged 65 years or more, is expected to be globally about 2 billion. Simultaneously, a “technological tsunami” related to advances in digital technology and especially mobile telephony and the internet and accompanied by cloud computing and the Internet of Things has appeared. In this article the role of mobile technologies towards the quality of life improvement for the aged population is investigated in an effort to answer the question: “will these two tsunamis operate in a synergistic manner for the benefit of the third age?”
User Experience of an Institutional Repository in a Private University in Mexico
Authors: González-Pérez Laura Icela , Ramírez María Soledad
Published: September 2019

Technology platforms, as viewed from the perspective of their users, provide new perspectives to discover aspects to enhance its use. The objective of this study is to provide the instruments and indicators that allow us to obtain empirical evidence of the experience of users of an institutional repository through the user-centered design methodology. The guiding question of the study was: How can society measure the experience of users who use an institutional repository? The authors employed a sequential mixed explanatory methodology and user-centered design, with the use of focus groups and surveys, applied to a sample of students and professors. The findings suggest that three key aspects could be considered to promote satisfactory experiences of users in relation to the open educational movement: a) innovation in communication strategies to increase knowledge transfer in an open format, b) the versatility of the technologies and c) establish the normativity and regulation of their use of institutional repositories.
Genetic linkage map and mapping of the locus of biological nitrogen fixation inefficiency in cowpea
Authors: Seido Sirando Lima , Fernandes Santos Carlos Antonio
Published: September 2019

The objectives of the present study were to construct a cowpea genetic map using the F2 population resulting from the cross IC-1 x BRS Marataoã, based on single nucleotide polymorphism (SNP) markers, and to map the cpi gene, with additional reference to introgression with the consensus map of species, aiming to identify markers for assisted selection to develop more efficient cultivars for BNF. The parents and 89 F2 plants were genotyped with 51,128 SNP markers, of which 910 polymorphic markers were used to construct the map. The results revealed 11 linkage groups, with an average of 82 markers per chromosome and average distance of 1.26 cM between markers. Recombination analysis of the SNPs indicated that markers 2_12850 and 2_00188, located in linkage group 11, flanked the cpi gene at a distance of 6.7 cM and 5.64 cM, respectively. The introgression of linkage group 11 with the cowpea reference map revealed short distances (from zero to 0.6 cM) for these markers, indicating a strong association with the cpi gene. The constructed map and cpi mapping provide basic information that can assist the genetic breeding of more efficient cowpea plants for BNF by marker-assisted selection.
Selection of interspecific Psidium spp. hybrids resistant to Meloidogyne enterolobii
Authors: Ribeiro Rodrigo Moreira , Martins Gomes Vicente , Pio Viana Alexandre , Moreira Souza Ricardo , Santos Paulo Ricardo dos
Published: September 2019

Since 2001, the disease known as 'guava decline', resulting from the interaction between the phytonematode Meloidogyne enterolobii and the fungus Fusarium solanie, has caused direct and indirect economic losses to the entire guava production chain. Given the lack of sources of resistance in guava genotypes, interspecific hybrids of Psidium spp. were obtained for resistance to the nematode M. enterolobii. To classify the level of resistance of the interspecific hybrids, we evaluated the plant classification methodologies proposed by Oostenbrink (1966) and Moura and Régis (1987). Estimates of genetic parameters were obtained using the REML/BLUP approach. Interspecific hybrids resistant to M. enterolobii were selected that can be used as rootstocks or in new crosses for the development of the guava breeding program.

Authors: Costa Jéfferson de Oliveira , Duarte Coelho Rubens , Barros Timóteo Herculino da Silva , Fraga Júnior Eusímio Felisbino , Fernandes André Luís Teixeira
Published: September 2019

The leaf area index (LAI) is relevant in studies of phenomena at different scales, such as for the leaf to canopy scale and the calculation of the extinction coefficient of photosynthetically active radiation (kPAR), providing input for the parameterization of physiological basis models. The objective of this work was to verify the variation of the LAI and the coffee kPAR subjected to different drip irrigation levels (130, 100, 70, and 40%) and to compare the data obtained from radiation bar linear sensors (SunScan) in the plants that received full irrigation with the values found by other LAI estimation methodologies. The study was conducted in Piracicaba, São Paulo State, Brazil, using the species Coffea arabica cv. Red Catuaí IAC 144; a drip irrigation system was adopted, with the irrigation controlled by tensiometry. The mean LAI values were higher in the L130 (irrigation level of 130%) and L100 (irrigation level of 100%) treatments than those with deficit irrigation depths. The mean kPAR values were lower for the L130 and L100 treatments than the values found in the deficit irrigation depth treatments. When comparing SunScan to other methodologies, the mean error (ME) and absolute mean error (AME) were high.
Selection of parents for low nitrogen stress through the combining ability of maize partially inbred lines
Authors: Heinz Rafael , Ribeiro Larissa Pereira , Gonçalves Manoel Carlos , Bhering Leonardo Lopes , Teodoro Paulo Eduardo
Published: September 2019

The objective of this work was to estimate the general combining ability of partially inbred lines under high and low nitrogen (N) conditions and to select promising lines to obtain high yields for both conditions. Fifty-five partially inbred S1 progenies were evaluated using the top-cross method, where the lines were crossed with two testers. The 110 top-cross hybrids were evaluated for grain yield during the off-season of 2012 at two sites in the Brazilian Midwest. Partial diallel analysis was performed with the adjusted means of each of the individual analyses of the top crosses. The combining ability of partially inbred lines and testers as well as their interaction with N levels, was estimated for each site. The coefficient of concordance among 15 partially inbred lines selected by the highest general combining ability estimates for each N level was 0.60. The S1 lines 39, 11, 41, 55, 38, 37, 6, 8, and 14 were selected at both N levels. This indicates that these lines can be used to identify ideal hybrids for growing in the off-season in the Brazilian Midwest.

Published: September 2019

Modifications were made in the PCR conditions aiming to overcome the problem of non-amplification of the Xanthomonas phaseoli pv. manihotis (Xpm) fragment, using the primer pair XV / XK described in the literature. The objective of this study was to propose changes in the primers already described (XV / XK_MOD) and validate the use of these new primers in identifying Xpm. The validation procedure was carried out with the primer pair XV and XK_MOD, using different strains of Xpm, other plant pathogenic and endophytic bacteria genera and one isolate of X. phaseoli pv. passiflorae. As a control, additional reactions were conducted in multiplex with the universal primers for the 16S rRNA gene of the bacteria together with XV / XK and XV / XK_MOD. Using the forward primer (XV) described in the literature together with the modified reverse primer (XK_MOD), it was possible to achieve amplification from DNA extracted from in vitro cultures and from infected tissue, but no amplification was noticed for the primer pair described in the literature, confirming the effectiveness of the proposed modification.
Simultaneous involvement of optic and abducens nerves by Lyme disease: Case report with review of the literature
Authors: Dabiri Iman , Burakgazi Ahmet Z.
Published: September 2019

Ocular manifestations of Lyme disease (LD) remain a rare feature of the disease, but it may present a wide range of clinical presentations with different combinations. LD related optic neuritis or cranial nerve (CN) six palsy have been reported in the literature. However, this is the first case report of simultaneous involvement of CN 2 and CN 6 in a patient with LD. The diagnosis of LD can be challenging and initial laboratory tests can be a false negative. It is paramount important to repeat the diagnostic test if clinical suspicious is ongoing. With this case, we aim to increase awareness of clinicians for possible ocular manifestations of LD and its complex diagnostic process.
Automated surface water extraction from RapidEye imagery including cloud and cloud shadow detection
Authors: Olthof I
Published: September 2019

Mapped surface water extents represent fundamental geospatial information required by a large number of public and private sector stakeholders in Canada. Currently available surface water maps from Canada's National Hydrographic Network (NHN) are out-of-date in
many locations in part due to the vintage of the maps themselves, and also because water extents are dynamic and changing. Previously, a significant amount of Canada's NHN base geospatial data was manually interpreted from airphotos and other sources of high-resolution imagery, which enabled
detailed mapping but required significant human and financial resources. Satellite imagery can provide a cheaper alternative due to the free availability of certain data and potential for automated feature extraction. Freely available medium resolution data from sensors such as Landsat can provide
information at a scale of 1:50 k while more detail is needed to map smaller water courses that can only be resolved from high resolution sensors (< 5 m) such as RapidEye. This Open File describes a robust, fully automated procedure to extract surface water from RapidEye imagery including
cloud and cloud shadow screening, as a potential method to enhance future NHN updating. The method is applied to RapidEye imagery residing in the Government of Canada's image archive over the St-John, Red and Richelieu Rivers. Qualitative assessment of the Richelieu product shows high overall
agreement with water features in Google Earth imagery and NHN, with errors stemming from spectral confusion with dark soil and urban shadow. Canada's RapidEye archive currently covers approximately 30 % of provinces while its 5 m spatial resolution provides a good compromise between detail and
data volume that can be processed on modern workstations. Similar spectral bands available in other higher resolution satellite sensors (< 2 m) such as WorldView suggest more detailed surface water extents may become available using methods developed here and adapted to these
sensors.
Project:Filter - Using Applied Games to Engage Secondary Schoolchildren with Public Policy
Authors: Reid Andrew James
Published: September 2019

Applied games present a twenty-first-century method of consuming information for a specific purpose beyond pure entertainment. Objectives such as awareness and engagement are often used as intended outcomes of applied games in alignment with strategic, organizational, or commercial purposes. Applied games were highlighted as an engagement-based outcome to explore noPILLS, a pan-European policy research project which presented policy pointers and suggested methods of interventions for reducing micropollution within the wastewater treatment process. This paper provides an assessment of a video game which was developed for the purpose of public engagement with policy-based research. The video game, Project:Filter, was developed as a means of communicating noPILLS to secondary school children in Scotland as part of a classroom-based activity. Knowledge development and engagement were identified using Interpretative Phenomenological Analysis to evidence topical awareness, depth of understanding, and suggested methods of intervention. Analysis of observations also provided insights into challenges surrounding logistics, pedagogy, social interactions, learning, and gender as contributing factors to the schoolchildren’s experiences of Project:Filter. The intention of this paper is two-fold: firstly, to provide an example of developing video games from policy-based research; and secondly, to suggest methods of phenomenological assessment for identifying play-based engagement.
The experiences of parents of children living with disabilities at Lehlaba Protective Workshop in Sekhukhune district of Limpopo province
Authors: Tigere Brian , Makhubele Jabulani C.
Published: September 2019

Background: Parents of children with disabilities have faced difficulties in looking after their children, be it socially, economically and financially. Parents in rural areas are mainly left with a huge burden, as there is a lack of services and support from both the state and non-governmental organisations. Parents in Sekhukhune district, a rural area in Limpopo province of South Africa, face challenges in raising their disabled children related to lack of resources and lack of services at their disposal.Objectives: This study focuses on the experiences and life circumstances faced by parents of children living with different types of disabilities at Lehlaba Protective Workshop in Sekhukhune district of Limpopo province, South Africa.Method: The study consisted of 14 participants who are parents of children living with disabilities. An interview guide with a set of questions was utilised to gather data. Thematic analysis was used to analyse the data and themes that emerged were grouped together.Results: Themes that emerged from the data showed that most of the participants had varying understandings on the causes of disabilities to their children. The participants also were of the view that a ‘cure’ for disability was available medically, spiritually or through traditional African medicine. The study also brought the notion of absent fathers, as most men do not want to be associated with children who are disabled. Stigmatisation of the parents was also a theme that the study revealed. The parents are subjected to name labelling as they are viewed to be practising witchcraft or to be paying for their sins they committed.Conclusion: Parents of children with disabilities are in their own battle in raising their children. There is a lack of support structures available for parents of children living with disabilities.

Calcium ions are usually present at high concentrations in brines produced with oil and gas. Such brines are typically saturated with respect to CaCO3. Consequently, precipitation of CaCO3 as scale on the internal wall of the pipeline can readily occur due to changes in operational and environmental parameters as produced fluids are transferred from downhole to surface facilities. Despite its importance, there is minimal research in the literature addressing the effect of calcium ions, and specifically CaCO3 scale, on the CO2 corrosion mechanism. The main objectives of this research are to further broaden the mechanistic understanding of CO2 corrosion of mild steel in the presence of high concentrations of calcium ions and evaluate the protectiveness that FexCayCO3 and CaCO3 scale confers against further corrosion. The corrosion behavior was studied in situ by electrochemical methods, including linear polarization resistance and open-circuit potential, along with weight loss using a UNS G10180 steel with ferritic-pearlitic microstructure. Surface characterization of the scale and corrosion product was performed using scanning electron microscopy, energy dispersive x-ray spectroscopy, and x-ray diffraction. A descriptive model is proposed for the CO2 corrosion mechanism of mild steel in the presence of high concentrations of calcium ions. Unprotective FexCayCO3 (y>x) and CaCO3 scales were observed to act as a mass transfer barrier that could promote surface conditions favoring FeCO3 precipitation. The presence of uniform CaCO3 scale did not result in the onset of localized corrosion at the conducted experimental conditions.

Parent-adolescent conflicts and depressed mood among Surinamese-Hindustani female adolescents in the Netherlands: an online daily diary study

Suicidal behavior is two to four times more common in Surinamese-Hindustani than in Dutch young women in the Netherlands. The decreased well-being of these adolescents is often related to a poor relationship with their parents. To date, quantitative studies in which the relation between an increased risk of depression, an important risk factor for suicide, and the parent-adolescent relationship in this ethnic-cultural group is investigated are lacking. In an attempt to understand this relation better, we conducted an online daily diary study on differences between Surinamese-Hindustani and Dutch adolescents (age 16-26) with regard to depressed mood, frequency of parent-adolescent conflicts, topics of conflict, and the strength of the relationship between the number of parent-adolescent conflicts and depressed mood. The adolescents completed questionnaires, including the Beck Depression Inventory (BDI), followed by a 14-day online daily diary tracking the frequency and topics of parent-adolescent conflicts, as well as general affect. Analyses revealed that (1) there were no differences between Surinamese-Hindustani and Dutch participants regarding depressed mood and frequency of parent-adolescent conflicts (2) Surinamese-Hindustani participants experienced more conflicts with their parents about autonomy than Dutch participants (3) the frequency of parent-adolescent conflicts was related to depressed mood among Dutch, but not among Surinamese-Hindustani participants.
Inverting the Gaze from California

Published: September 2019

The epilogue contemplates writing this book from Luiseño land, specifically focusing on a park created in Oceanside, California, the ancestral lands of the San Luis Rey Band of Indians. The epilogue highlights the endurance of oral literature as well as writing throughout indigenous territory. It meditates on Mesoamerican literature as a new sign of Latin America’s transition from officially Spanish-speaking and mestizo to recognizing and affirming its multilingual and intercultural distinction.
The Smugglers' World
Authors: Cromwell Jesse
Published: September 2019

The Smugglers’ World: Illicit Trade and Atlantic Communities in Eighteenth-Century Venezuela reinterprets the meaning of illicit commerce in the early modern Atlantic. More than simply a transactional relationship or a political economy concern of empires, smuggling became a societal ethos for the communities in which it was practiced. For most of the colonial period, subjects of the commercially neglected province of Venezuela depended on contrabandists from the Dutch, English, and French Caribbean. These illegal yet scarcely patrolled rendezvous came under scrutiny in the eighteenth century as Bourbon reformers sought to regain control and boost productivity in the province. Subsequent crackdowns on smuggling sparked colonial tensions. Illicit trade created interimperial connections and parallel communities based around provisioning as a moral necessity. It threw the legal status of people of color aboard ships into chaos. Smuggling’s participants normalized subversions of imperial law and proffered mutually agreed-upon limits of acceptable extralegal activity. Venezuelan subjects defended their commercial autonomy through passive measures and occasionally through violent political protests. This commercial discourse between the state and its subjects was a key part of empire making and maintenance in the early modern world.
Introduction
Authors: Cromwell Jesse
Published: September 2019

The introduction discusses the twin market factors leading to illegal commerce: the rise of cacao and dearth of European consumer goods. It points out the colony’s location vis-à-vis non-Spanish Caribbean colonies (Curaçao in particular) and includes maps of the Venezuelan coast. The introduction articulates that this is a rich case study owing to Venezuela’s transition from imperial neglect to the object of persistent and forceful metropolitan reform efforts. It makes three broad arguments. First, communities on the coastal peripheries of empire formed ground-up moral economies that included contraband trade as a basic tenet within them. Second, subjects and officials living in areas of endemic illicit trade agreed upon acceptable levels of criminality and corruption. My book’s third argument is a larger articulation of this sense of negotiation. I contend that illicit trade in the Spanish Atlantic is, in fact, a story of empire making. Many coastal and maritime-oriented subjects felt a sense of statelessness that was intolerable by the standards of imperial law. Confounded by changes to the rules of commercial engagement and an uptick in enforcement, many otherwise loyal Spanish subjects still traded in an economy that was illegal by their empire’s strictures.
Old Habits
Authors: Cromwell Jesse
Published: September 2019

This chapter asks what the implicit understandings were between empire and colony for almost two hundred years before the change to Bourbon governance and an eighteenth-century period of commercial conflict. It discusses briefly how the Spanish Empire addressed smuggling in the immediate decades after Caracas’s mid-sixteenth-century founding, then moves to the seventeenth-century transition to an almost monocrop, cacao-based economy and the rise of interimperial contact that accompanied it. The chapter ends shortly before the establishment of the Caracas Company in 1728. It also includes a basic primer to the Spanish commercial system meant to give the reader a sense of exactly how illicit trade deviated from imperial guidelines. Chapter one functions as an examination of the Habsburg status quo of benign neglect that governed Venezuela from its inception until the rise of the Caracas Company. It argues that this was a colony that received little commercial support but also little outside intervention where extralegal interimperial trade was concerned.
Socialized into Smuggling
Authors: Cromwell Jesse
Published: September 2019

The chapter analyzes the cultural value of smuggled goods in Spanish America and Europe as a means to understand the acculturation to illicit activity that early modern Venezuelans experienced. For their cacao, Venezuelans received, not the exotic items typically associated with illicit trade, but rather mundane wares and foodstuffs such as flour, coarse cloth, liquor, and firearms. Inventories of contraband confiscated from homes and businesses suggest both the tremendous inability of the Spanish Empire to supply its more marginal colonies with simple trade and the ways that Venezuelans creatively used smuggling to deal with this dearth of subsistence goods. Furthermore, court cases of smuggling highlight the importance of women as retail distributors of contraband on land. All of these circumstances revealed the colonists’ viewpoint on illegality: the cultural superiority manifested in consuming even simple European items merited the complications of illicit trade including bloodshed, commercial policing, and property confiscation. Black-market commerce at even the pettiest levels initiated coastal residents into a criminal world where they developed justifications and subterfuges for their everyday actions. In essence, residents had been socialized into smuggling.
The Societal Ties of Smuggling
Authors: Cromwell Jesse
Published: September 2019

Chapter 5 investigates the other half of the interimperial transaction: domestic smugglers in Venezuela. This chapter offers a greater sense of how participants in illicit trade interacted with their home environments. Not all Venezuelan smugglers were alike. Similar to their foreign counterparts, domestic contrabandists were mostly small-time traders earning a living outside of the law after being shut out of the lucrative legal cacao trades with Spain and Mexico by larger merchant and agricultural concerns. Yet, unlike non-Spanish smugglers, Venezuelan participants in illegal trade had to make their homes in the same place where they broke the law. Their uneasy existence was possible because of local contrabandists’ entrenchment in bureaucratic, ecclesiastical, kinship, and criminal groups. The strength of these connections, along with an individual’s wealth and the flagrancy of their transgressions, often determined the likelihood that they would face prosecution. Highlighting these perspectives foreshadows the rebellion of chapter eight and also demonstrates that Venezuelan smugglers believed that, through on-the-ground experience in legal and illegal trading, they knew best how to sustain their livelihoods within the bonds of empire.
