Real-Time Control Strategy of Fuel Cell and Battery System for Electric Hybrid Boat Application
Authors: Al Amerl Ahmed , Oukkacha Ismail , Camara Mamadou Baïlo , Dakyo Brayima
Published: August 2021

In this paper, an effective control strategy is proposed to manage energy distribution from fuel cells and batteries for hybrid electric boat applications. The main objectives of this real-time control are to obtain fast current tracking for the batteries’ system, the DC bus voltage stability by using a fuel cell, and energy load distribution for a hybrid electric boat under varying demand conditions. The proposed control strategy is based on a combination of frequency approach and current/voltage control of interleaved boost converters to reduce the hydrogen consumption by the fuel cell and improve the quality of energy transfer. The frequency approach was dedicated to managing the DC power-sharing between the load, the fuel cell, and the batteries’ storage system by extracting the power references. The closed loop control system utilized to control the energy is based on the DC/DC converters. The performance evaluation of the proposed control strategy has been tested through a real-time experimental test bench based on a dSPACE board (DS1104).

Published: August 2021

Sustainable management of canal water through optimum water allocation is the need of the modern world due to the rapid rise in water demand and climatic variations. The present research was conducted at the Chaj Doab, Indus Basin Irrigation System (IBIS) of Pakistan, using the WEAP (Water Evaluation and Planning) model. Six different scenarios were developed, and the results showed that the current available surface water is not sufficient to meet crop water demands. The Lower Jhelum Canal (LJC) command area is more sensitive to water scarcity than the Upper Jhelum Canal (UJC). The future (up to 2070) climate change scenarios for RCP 4.5 and 8.5 showed a decrease in catchment reliability up to 26.80 and 26.28% for UJC as well as 27.56 and 27.31% for LJC catchment, respectively. We concluded that scenario 3 (irrigation efficiency improvement through implementation of a high efficiency irrigation system, canal lining, reduction and replacement of high delta crops with low delta crops) was sufficient to reduce the canal water deficit in order to optimize canal water allocation. Improvement in the irrigation system and cropping area should be optimized for efficient canal water management.
The Development of Autonomous Student Learning Networks: Patterns of Interactions in an Open World Learning Environment for Teachers Exploring Teaching with and through Computer Science
Authors: Ardito Gerald , Czerkawski Betül
Published: August 2021

This pilot case study sought to investigate patterns of interactions between learners and their instructor in a teacher education course called “Computer Science for Teachers”. This course was constructed to leverage aspects of open world game design elements in order to investigate the effects of degrees of autonomy in gameplay/learning. This course was conducted in a specially built social learning platform based on Elgg software. Student interactions with the instructor and other students in this course were analyzed to determine the learning networks students constructed during each key learning activity as well as the epistemic spaces defined by these interactions. Descriptive statistics along with social network analysis (SNA) and epistemic network analysis (ENA) were used to investigate these data. The findings indicate that more traditional/less open world gaming type learning activities were associated with learning networks and epistemic spaces that were teacher-centered and narrower, while more open world gaming/high levels of autonomy (student-centric) learning activities were associated with learning networks that were highly decentralized and epistemic spaces that featured students asking and answering questions of/for one another. These findings were consistent with existing research into player behavior in open world type games and learner behavior in settings with high levels of autonomy support. Implications for further research are discussed.
Towards a Just Energy Transition, Barriers and Opportunities for Positive Energy District Creation in Spain
Authors: Hearn Adam X. , Castaño-Rosa Raul
Published: August 2021

To mitigate the effects of climate change, the European Commission created a Strategic Energy Technology Plan committing to forming 100 Positive Energy Districts (PEDs) by 2025. These are considered to potentially be major instruments for decarbonization in a just transition. This plan has led to some districts being defined as PEDs, although none have fully met the criteria to be a PED yet. Research shows that new forms of energy ownership and production, as could potentially be found in PEDs, could help reduce energy poverty, which affects a significant segment of the population, as households can reduce their energy expenditure as well as improve their energy behavior. This paper set out to shed light on the PED landscape, investigating the barriers and opportunities to PED creation in Spain and its potential to mitigate energy poverty. We conducted a literature review on community-owned energy in Spain, followed with expert interviews (energy researchers, stakeholders, and NGOs) who focus on sustainability issues in Spain. Results show a number of barriers (lack of knowledge and awareness, and lack of trust from consumers) and opportunities connected with the creation of PEDs. In conclusion, policymaker engagement and support play a key role in successfully implementing PEDs.
Evaluating Mine Design Alternatives for Social Risks Using Discrete Choice Analysis
Authors: Awuah-Offei Kwame , Que Sisi , Ur Rehman Atta
Published: August 2021

As with other engineering design tasks, mine design involves setting design objectives and constraints (the feasible solution space) and finding the optimal design alternative. Mine engineers often struggle to incorporate the preferences of local community members into their evaluation of mine design alternatives because the mining literature lacks tools to quantify such risks during mine planning. This paper presents an approach to evaluate community acceptance (i.e., community preferences for the alternatives) using discrete choice models and decision-based design during mine planning. Using discrete choice models and a rigorous framework, engineers can estimate the cost of social risks as a function of the probability that individuals in the host community will prefer a particular design alternative. They can then estimate the overall utility of a particular design alternative to the project proponents. This paper illustrates the proposed approach with a strategic mine planning exercise for a gold mine. The framework can be a useful tool for designing mines for sustainability, if combined with effective community engagement and management’s commitment to creating shared value.
Optimal Urban Transit Investment Model and Its Application
Authors: Sharav Nir , Shiftan Yoram
Published: August 2021

We present a new urban transit investment model, integrating transport economic theory regarding optimal investment with transport modeling, planning, and network design. The model expands on the theory of optimal transit network planning and investment, accounting for the effects of the investment on accessibility, level of service, and speed. The model seeks long-term optimal transit investment and optimal road pricing simultaneously in an integrated, unified model. To illustrate the advantages of our approach, we applied our empirical model to two case studies, Tel Aviv and Toronto, integrating our theoretical contribution into practice. Our results demonstrate the model’s ability to indicate the optimal transit mode and investment on a corridor level and the total investment required for the city transit network. The model results were compared to the actual and planned transit networks of Tel Aviv and Toronto and showed the model’s capability to produce a good balance of strategic design and network details. The research concludes that applying the right toll with the applicable transit investment is crucial for obtaining an efficient network and performance. This research can direct planners and policymakers in planning urban transport and provide a comprehensive set of guidelines for optimizing the simultaneous investment in mass transit and the congestion toll toward more sustainable cities and transportation systems.

Authors: Linhares Rafael M. , Bersot Carlos Darcy A. , Pereira José Eduardo G. , Galhardo Carlos , Lessa Marcos Adriano , Kietaibl Sibylle
Published: August 2021

Introduction: This systematic review aims to summarize the existing evidence relating to preoperative anemia and clinical outcomes in peripheral vascular surgery patients. Methods: The following databases were searched—PubMed, COCHRANE, LILACS, and Science Research—from 1 January 2010 up to 8 May 2020, with the last search performed on 1 January 2021. An additional manual search for potential primary studies was conducted on major journals (e.g., Anesthesiology, the British Journal of Anesthesia and the European Journal of Anaesthesiology) and reference lists of included studies. Google Scholar was also checked for additional eligible studies. Reviewers independently screened potentially eligible articles and extracted data from included studies on populations, interventions, comparisons, and outcomes. This review was registered at PROSPERO as CRD 180954. Results: In total, 6 observational studies with a combined total of 87,327 participants were analyzed. Data collected in this review suggest that preoperative anemia, especially when hemoglobin is <10 g/dL, is associated with an increased risk of red blood cell transfusions (OR: 7.5; 95% CI 6.3–8.9, p < 0.0001), limb amputation (OR: 5.2; 95% CI 3.1–8.6, p < 0.0001), and death (p < 0.0031). Conclusions: These data suggest an association between preoperative anemia, blood transfusion requirements, and other adverse clinical outcomes among patients subjected to peripheral vascular interventions. However, further investigations, particularly randomized controlled trials, are warranted to better understand the association between preoperative anemia and patients’ prognosis.

Published: August 2021

Post-operative analgesic management is challenging in infants and opioids have been the standard of care. However, they are associated with adverse effects which may negatively impact infants. In this retrospective cohort study, we sought to explore the postoperative analgesic efficacy of quadratus lumborum (QL) block in the infant population undergoing dorsal lumbotomy pyeloplasty. Chart review of 34 infants (≤12 months) who underwent dorsal lumbotomy pyeloplasty between 2016–2020 was performed. Post-operative pain was assessed using externally validated pain scales (CRIES & FLACC) and monitored hemodynamics (pulse and blood pressure). Opioid doses were standardized by using morphine milligram equivalency (MME). The Prescription Database Monitoring Program (PDMP) was utilized to determine if discharge opioid prescriptions were filled. Of 34 patients, 13 received the QL block. Mean age at the time of surgery was 6.2 months ± 3.2 months. The QL group received 0.8 MME postoperatively, whereas the non-QL group received 0.9 MME (p = 0.82). The QL group (20%) filled their discharge opioid prescription less frequently compared to non-QL group (100%) (p = 0.002). There were no observed differences between pain scale or hemodynamic variables. Further studies are warranted to explore QL block’s efficacy for post-operative infant pain management.
Bateson and Wright on Number and Quantity: How to Not Separate Thinking from Its Relational Context
Authors: Fisher William P.
Published: August 2021

As part of his explication of the epistemological error made in separating thinking from its ecological context, Bateson distinguished counts from measurements. With no reference to Bateson, the measurement theory and practice of Benjamin Wright also recognizes that number and quantity are different logical types. Describing the confusion of counts and measures as schizophrenic, like Bateson, Wright, a physicist and certified psychoanalyst, showed mathematically that convergent stochastic processes informing counts are predictable in ways that facilitate methodical measurements. Wright’s methods experimentally evaluate the complex symmetries of nonlinear and stochastic numeric patterns as a basis for estimating interval quantities. These methods also retain connections with locally situated concrete expressions, mediating the data display by contextualizing it in relation to the abstractly communicable and navigable quantitative unit and its uncertainty. Decades of successful use of Wright’s methods in research and practice are augmented in recent collaborations of metrology engineers and psychometricians who are systematically distinguishing numeric counts from measured quantities in new classes of knowledge infrastructure. Situating Wright’s work in the context of Bateson’s ideas may be useful for infrastructuring new political, economic, and scientific outcomes.
The Dynamic Analysis of a Novel Reconfigurable Cubic Chaotic Map and Its Application in Finite Field
Authors: Wang Chuanfu , Di Yi , Tang Jianyu , Shuai Jing , Zhang Yuchen , Lu Qi
Published: August 2021

Dynamic degradation occurs when chaotic systems are implemented on digital devices, which seriously threatens the security of chaos-based pseudorandom sequence generators. The chaotic degradation shows complex periodic behavior, which is often ignored by designers and seldom analyzed in theory. Not knowing the exact period of the output sequence is the key problem that affects the application of chaos-based pseudorandom sequence generators. In this paper, two cubic chaotic maps are combined, which have symmetry and reconfigurable form in the digital circuit. The dynamic behavior of the cubic chaotic map and the corresponding digital cubic chaotic map are analyzed respectively, and the reasons for the complex period and weak randomness of output sequences are studied. On this basis, the digital cubic chaotic map is optimized, and the complex periodic behavior is improved. In addition, a reconfigurable pseudorandom sequence generator based on the digital cubic chaotic map is constructed from the point of saving consumption of logical resources. Through theoretical and numerical analysis, the pseudorandom sequence generator solves the complex period and weak randomness of the cubic chaotic map after digitization and makes the output sequence have better performance and less resource consumption, which lays the foundation for applying it to the field of secure communication.
Three Roads to the Geometric Constraint Formulation of Gravitational Theories with Boundaries
Authors: Barbero Fernando , Basquens Marc , Varo Valle , Villaseñor Eduardo J. S.
Published: August 2021

The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most popular of them being the one developed by Dirac. Here, we discuss other approaches to this problem that rely on the direct use of the equations of motion (and the tangency requirements characteristic of the Gotay, Nester and Hinds method), or are formulated in the tangent bundle of the configuration space. Owing to its interesting relation with general relativity we use a concrete example as a test bed: an extension of the Pontryagin and Husain–Kuchař actions to four dimensional manifolds with boundary.
Mediterranean Subspecies versus Californian Varieties: An Example from Acmispon (Leguminosae, Loteae)
Authors: Sokoloff Dmitry D. , Akulova-Barlow Zoya V. , Govaerts Rafaël
Published: August 2021

The tribe Loteae of the family Leguminosae has major centers of diversity in the Mediterranean Region and California. It is used here to illustrate different traditions of taxonomic interpretation of infraspecific variation among researchers in different continents. Recent accounts of European and Mediterranean taxa commonly make an emphasis on recognizing subspecies. In contrast, accounts of North American Loteae recognize all infraspecific taxa as varieties. Harmonization of taxonomic concepts across continents is essential for a more accurate representation of data in global biodiversity databases. It is reasonable to use the rank of subspecies for geographically defined infraspecific units with localized zones of intergradation. Such subspecies may be at least partially compatible across continents and taxonomic groups. In the present paper, we discuss taxa traditionally included in or associated with Acmispon glaber (Vogel) Brouillet (=Syrmatium glabrum Vogel) and demonstrate a need for recognizing three species, of which one has three geographically defined subspecies. Required nomenclatural combinations are proposed. It is proposed that subspecies rather than varieties should be recognized in a number of other species of North American Loteae (and other plant groups). Inland subspecies of Acmispon glaber and A. maritimus offer an opportunity for comparative analysis in an eco-evo-devo framework.

Published: August 2021

Cholera toxin B-subunit (CTxB) has emerged as one of the most widely utilized tools in membrane biology and biophysics. CTxB is a homopentameric stable protein that binds tightly to up to five GM1 glycosphingolipids. This provides a robust and tractable model for exploring membrane structure and its dynamics including vesicular trafficking and nanodomain assembly. Here, we review important advances in these fields enabled by use of CTxB and its lipid receptor GM1.
Observational Characterization of the Ecological and Environmental Features Associated with the Presence of Oropouche Virus and the Primary Vector Culicoides paraensis: Data Synthesis and Systematic Review
Authors: Walsh Christine , Robert Michael , Christofferson Rebecca
Published: August 2021

Oropouche virus (OROV), a member of the Orthobunyavirus genus, is an arthropod-borne virus (arbovirus) and is the etiologic agent of human and animal disease. The primary vector of OROV is presumed to be the biting midge, Culicoides paraensis, though Culex quinquefasciatus, Cq. venezuelensis, and Aedes serratus mosquitoes are considered secondary vectors. The objective of this systematic review is to characterize locations where OROV and/or its primary vector have been detected. Synthesis of known data through review of published literature regarding OROV and vectors was carried out through two independent searches: one search targeted to OROV, and another targeted towards the primary vector. A total of 911 records were returned, but only 90 (9.9%) articles satisfied all inclusion criteria. When locations were characterized, some common features were noted more frequently than others, though no one characteristic was significantly associated with presence of OROV using a logistic classification model. In a separate correlation analysis, vector presence was significantly correlated only with the presence of restingas. The lack of significant relationships is likely due to the paucity of data regarding OROV and its eco-epidemiology and highlights the importance of continued focus on characterizing this and other neglected tropical diseases.

Optimal biosafety and biosecurity are major requirements of global health security. This study assessed the biorisk management in the reference veterinary laboratory of Parakou (Benin). The study was cross-sectional, descriptive, and evaluative. The non-probability sampling method with the reasoned choice was used. The Food and Agriculture Organization laboratory mapping tool-safety was used to collect information from the laboratory team. Group discussion, working environment observation, and document exploitation were the data collection techniques. The biorisk management was rated good if the average indicator of the laboratory reached at least 80%. Otherwise, the biorisk management was rated insufficient. The overall laboratory biosafety and biosecurity score was insufficient (42.4%). Per area, the scores were 26.7% for engineering, 33.3% for administration, 53.8% for personal protective equipment, and 62.3% for the operational. There was no area or category score that reached 80%. Containment, waste disposal, and personal protective equipment disposal were the best performing categories with a score above 60%. The laboratory has no biosafety and accident prevention program. Its premises require renovation. The standard operating procedures for biosafety are not yet finalized, and the training mechanism is not optimal. Therefore, strong advocacy and implementation of a biorisk management improvement plan appear as urgent corrective actions which are required to help the reference veterinary laboratory of Parakou in its task to protect the livestock and, ultimately, the people of Benin from dangerous diseases and emerging pathogens.

Published: August 2021

Venezuelan equine encephalitis virus (VEEV) is a new world alphavirus and a category B select agent. Currently, no FDA-approved vaccines or therapeutics are available to treat VEEV exposure and resultant disease manifestations. The C-terminus of the VEEV non-structural protein 3 (nsP3) facilitates cell-specific and virus-specific host factor binding preferences among alphaviruses, thereby providing targets of interest when designing novel antiviral therapeutics. In this study, we utilized an overexpression construct encoding HA-tagged nsP3 to identify host proteins that interact with VEEV nsP3 by mass spectrometry. Bioinformatic analyses of the putative interactors identified 42 small molecules with the potential to inhibit the host interaction targets, and thus potentially inhibit VEEV. Three inhibitors, tomatidine, citalopram HBr, and Z-VEID-FMK, reduced replication of both the TC-83 strain and the Trinidad donkey (TrD) strain of VEEV by at least 10-fold in astrocytoma, astroglial, and microglial cells. Further, these inhibitors reduced replication of the related New World (NW) alphavirus Eastern equine encephalitis virus (EEEV) in multiple cell types, thus demonstrating broad-spectrum antiviral activity. Time-course assays revealed all three inhibitors reduced both infectious particle production and positive-sense RNA levels post-infection. Further evaluation of the putative host targets for the three inhibitors revealed an interaction of VEEV nsP3 with TFAP2A, but not eIF2S2. Mechanistic studies utilizing siRNA knockdowns demonstrated that eIF2S2, but not TFAP2A, supports both efficient TC-83 replication and genomic RNA synthesis, but not subgenomic RNA translation. Overall, this work reveals the composition of the VEEV nsP3 proteome and the potential to identify host-based, broad spectrum therapeutic approaches to treat new world alphavirus infections.
Cytomegalovirus Infection Impairs the Mobilization of Tissue-Resident Innate Lymphoid Cells into the Peripheral Blood Compartment in Response to Acute Exercise

Published: August 2021

Circulating immune cell numbers and phenotypes are impacted by high-intensity acute bouts of exercise and infection history with the latent herpesviruses cytomegalovirus (CMV). In particular, CMV infection history impairs the exercise-induced mobilization of cytotoxic innate lymphoid cells 1 (ILC1) cells, also known as NK cells, in the blood. However, it remains unknown whether exercise and CMV infection modulate the mobilization of traditionally tissue-resident non-cytotoxic ILCs into the peripheral blood compartment. To address this question, 22 healthy individuals with or without CMV (20–35 years—45% CMVpos) completed 30 min of cycling at 70% VO2 max, and detailed phenotypic analysis of circulating ILCs was performed at rest and immediately post-exercise. We show for the first time that a bout of high-intensity exercise is associated with an influx of ILCs that are traditionally regarded as tissue-resident. In addition, this is the first study to highlight that latent CMV infection blunts the exercise-response of total ILCs and progenitor ILCs (ILCPs). These promising data suggest that acute exercise facilitates the circulation of certain ILC subsets, further advocating for the improvements in health seen with exercise by enhancing cellular mobilization and immunosurveillance, while also highlighting the indirect deleterious effects of CMV infection in healthy adults.
An Approach for Robust System Testing the Event Data Recorder in the Context of a Passive Safety System
Authors: Strassheim Alexander
Published: August 2021

As long as road accidents happen, passive safety systems like the airbag control unit are an essential part of the whole automotive safety system. Within the airbag control unit, the event data recorder (EDR) is an integrated function. Recent developments in legislation show that an increasing number of EDR-related regulations are being introduced. They are mainly focusing on data recording, crash-data retrieval, and some of them define testing aspects. In the system testing of an airbag control unit with a focus on the event data recorder, the question arises of how to deal with the fact that real-world crash events are not “straightforward” but arbitrary and do not follow any rules and restrictions. The purpose of this work is to develop a robust test approach to these conditions—giving a tester the possibility to extend the test depth considering the common test design techniques and testing principles. The applied methodology is the use of optimization algorithms in an automated test environment. With this, the tester can steer the test execution in a predefined way with minimal interaction. The application of the developed test method automatically creates a set of test data which fulfill the predefined conditions by the user. The generated results show that a high number of test data are created at and close to the target condition. Consequently, this test approach provides an extension to the common test design techniques with regard to how test input data can be created, and especially how automated test data creation and test execution can be realized.

Mapping of coastline changes assists in coastal development and monitoring. Athens Riviera, located in the southwestern coastal zone in Attica in central Greece, has undergone major and radical changes generated by human interference during the last decades. The aim of this paper is to map record and measure the coastline changes in Athens Riviera over the past 76 years. Aerial photographs and satellite images from 1945 to 2021 as well as geographic information system (GIS) techniques were used to depict the spatial and temporal variations of the coastline. The results show that 60% of the total length of the coastline is artificial coast, while 29% is rocky coast and 12% beach. The study of seven subareas showed that human interventions caused significant coastline changes in Faliro Bay, Alimos and Glyfada. The adjacent coastal regions to Athens metropolitan area illustrate the highest modifications in the coastline. The main changes in the coastlines are recorded from 1960 to 1987, while the rate of changes in coastline slowed down from 1987 to 2021. The total changes in the coastline of Athens Riviera demonstrate that, during the past 76 years, the coastline was enhanced by 40% while land reclaimed to the sea area approaches 2.67 km2. The applied method is effective and rapid and may utilize in the coastal monitoring and management.
A Novel Method to Assess the Impact of a Government’s Water Strategy on Research: A Case Study of Azraq Basin, Jordan

Published: August 2021

Water scarcity drives governments in arid and semi-arid regions to promote strategies for improving water use efficiency. Water-related research generally also plays an important role in the same countries and for the same reason. However, it remains unclear how to link the implementation of new government strategies and water-related research. This article’s principal objective is to present a novel approach that defines water-related research gaps from the point of view of a government strategy. The proposed methodology is based on an extensive literature review, followed by a systematic evaluation of the topics covered both in grey and peer-reviewed literature. Finally, we assess if and how the different literature sources contribute to the goals of the water strategy. The methodology was tested by investigating the impact of the water strategy of Jordan’s government (2008–2022) on the research conducted in the Azraq Basin, considering 99 grey and peer-reviewed documents. The results showed an increase in the number of water-related research documents from 37 published between 1985 and 2007 to 62 published between 2008 and 2018. This increase should not, however, be seen as a positive impact of increased research activity from the development of Jordan’s water strategy. In fact, the increase in water-related research activity matches the increasing trend in research production in Jordan generally. Moreover, the results showed that only about 80% of the documents align with the goals identified in the water strategy. In addition, the distribution of the documents among the different goals of the strategy is heterogeneous; hence, research gaps can be identified, i.e., goals of the water-strategy that are not addressed by any of the documents sourced. To foster innovative and demand-based research in the future, a matrix was developed that linked basin-specific research focus areas (RFAs) with the MWI strategy topics. In doing so, the goals that are not covered by a particular RFA are highlighted. This analysis can inspire researchers to develop and apply new topics in the Azraq Basin to address the research gaps and strengthen the connection between the RFAs and the strategy topics and goals. Moreover, the application of the proposed methodology can motivate future research to become demand-driven, innovative, and contribute to solving societal challenges.

Authors: Migliaccio Maurizio , Buono Andrea , Maltese Ila , Migliaccio Margherita
Published: August 2021

The COVID-19 pandemic has affected human life worldwide and forced the implementation of lockdown periods in order to reduce the physical interactions of people. Italy has been heavily affected by a large number of deaths. The government had to impose a long lockdown period during the spring of 2020. In this paper, we provide a critical analysis of the 2020 Italian spring lockdown (ISL) through observation of the spatiotemporal NOx pattern differences in connection with the social changes imposed by such restrictions. Different freely available sources of information are used: European Space Agency (ESA) TROPOspheric Monitoring Instrument (TROPOMI) measurements, ground-based measurements, and model estimates. The results show high NOx pollution levels, even during the lockdown, that suggest new approaches to sustainable mobility policies.

Objetivou-se determinar a eficiência e qualidade de atrativos alimentares na captura de Ceratitis capitata. Avaliou-se a eficiência de dois atrativos alimentares comerciais o Bio Anastrepha® e o CeraTrap® nas formas líquida e semissólida. O delineamento experimental usado foi em blocos casualizados em esquema fatorial (5 x 6 x 2 x 4) sendo: cinco (quatro atrativos + testemunha de água destilada), seis períodos de exposição dos atrativos no ambiente, dois sexos (adultos fêmeas e machos de C. capitata) distribuídos em quatro blocos. Os atrativos foram dispostos no ambiente telado em armadilhas do tipo frasco caça-mosca, onde foram liberados 300 adultos de C. capitata a cada período de exposição. Avaliou-se a atratividade (nº de insetos capturados) e qualidade das iscas alimentares (pH, proteína bruta %, conteúdo evaporado). Os atrativos líquidos capturaram mais C. capitata do que os semissólidos. A maior atratividade ao longo dos seis períodos de exposição foi do atrativo CeraTrap® liquida e a captura de insetos fêmeas foi maior em relação aos machos. O atrativo líquido CeraTrap® é o mais indicado para captura desse díptero.

A utilização de insetos conhecidos como inimigos naturais pode ser uma alternativa eficiente no controle dos pulgões que infestam a couve e a Euborellia annulipes se destaca por ser um predador bastante voraz desse grupo de insetos. Nesta pesquisa, foi avaliada a capacidade de busca do predador E. annulipes no controle do pulgão da couve-manteiga Brevicoryne brassicae. O trabalho foi desenvolvido no laboratório de Entomologia do Centro de Ciências Agrárias da Universidade Federal da Paraíba (CCA/UFPB). Os insetos foram obtidos da criação do laboratório de Entomologia, avaliando a capacidade de busca de ninfas de E. annulipes em diferentes distâncias sobre a dieta artificial e a capacidade de busca de machos e fêmeas de E. annulipes avaliando a preferência alimentar sobre diferentes idades do pulgão da couve em função das distâncias do alimento. Utilizou-se o Delineamento Inteiramente Casualizado (DIC) aplicando-se os dados a distribuição binomial negativa e as médias comparadas ao teste Tukey a 5% de probabilidade. Os resultados obtidos mostram que ninfas de E. annulipes apresentam boa capacidade de chegar até o alimento quando as distâncias variam de 10, 20 e 30 cm, assim como os adultos dessa espécie apresentam preferência alimentar por pulgões adultos e habilidade para percorrer longas distâncias em busca do seu alimento.

Trabalhos envolvendo o efeito da adubação orgânica e química sob as trocas gasosas na gravioleira ainda são restritos na literatura científica. Assim, o objetivo deste experimento foi avaliar as trocas gasosas em gravioleira ‘Morada’ sob adubação orgânica e mineral. Foi instalado um experimento em um pomar de gravioleira com 42 meses de idade entre os meses de janeiro a setembro de 2014. O solo foi classificado como Latossolo Amarelo Distrófico. O delineamento experimental foi em blocos casualizados, com sete tratamentos e quatro repetições, com duas plantas por parcela. Os tratamentos utilizados foram: T1= testemunha (sem adubação); T2= adubação mineral (NPK); T3= esterco de bovino; T4= esterco de aves; T5= adubação mineral + esterco de caprino; T6= esterco de aves + 3 kg de pó de rocha; T7= esterco de caprino. As variáveis analisadas foram: concentração interna de CO2, condutância estomática, taxa de transpiração, taxa fotossintética, eficiência de carboxilação e do uso da água. As avaliações foram feitas em campo, após 60 dias da última adubação nitrogenada, no período das 8 às 11 horas.  Os dados foram submetidos à análise de variância e ao teste de Tukey. A adubação mineral com NPK proporcionou maior taxa fotossintética e eficiência de carboxilação na gravioleira ‘Morada’. A concentração interna de CO2, condutância estomática, taxa de transpiração e eficiência de uso da água não foram afetadas pelos tratamentos.

Avaliação de respostas de Brachiaria brizantha cv. Marandu e Massai a diferentes doses de fósforo. O ensaio foi conduzido em casa de vegetação no IFMT – Campus Confresa, implantado em vasos plásticos de 5dm-³ com areia grossa lavada. O delineamento experimental em blocos casualizados, combinados em esquema fatorial 5x2, com quatro repetições para cada época de coleta (30 e 60 dias após emergência). Os tratamentos consistiram em aplicações de doses de fósforo (P), via solução nutritiva, correspondentes a concentração de P em solução equivale a 0,0; 36,9; 73,8; 110,8 e 147,6 mg dm-3. Para o material vegetal coletado foi obtida a massa seca em estufa de circulação de ar e posteriormente moídas separadamente (parte aérea e raiz) para a determinação da concentração de fósforo. Os dados foram submetidos à análise de variância a nível de 5% de probabilidade pelo teste F usando software Sisvar. Observando-se efeito significativo para dose, espécie e interação doses e espécie. A espécie Brachiaria revelou-se ser mais eficiente na absorção e transporte do nutriente P do que a espécie Massai, alcançando maior produção de massa seca e raiz, evidenciando ser mais responsiva a adubação fosfatada.

O leite é um dos produtos mais consumidos pela sociedade em todo o mundo, e esse consumo vem crescendo gradativamente no Brasil. Diante disto, a produção de leite é uma alternativa que pode ser muito rentável para os produtores e para a cadeia produtiva. Sabendo da necessidade dos produtores rurais em obter práticas eficientes para a produção, objetivou-se conhecer o processo de criação de gado leiteiro em uma propriedade rural localizada no município de Vila Rica e outra em Canabrava do Norte (MT). Foram analisadas as seguintes características: manejo, período de lactação, quadro reprodutivo e escore corporal de animais nessas propriedades. Para a produção dos dados utilizamos estudos bibliográficos em sites e artigos, além de pesquisa de campo. Os procedimentos utilizados foram questionários, observações e manuscritos. Ao analisar os resultados obtidos verificou-se que o acompanhamento técnico dessas propriedades é de suma importância para o produtor, visando garantir a boa produtividade dos animais. Percebe-se, ainda, que a propriedade que teve maior persistência no programa Nosso Leite da Embrapa (Empresa Brasileira de Pesquisa Agropecuária), obteve maior êxito em sua produtividade comparando-se com a outra propriedade.

A cultura do algodão se apresenta como uma alternativa rentável para os produtores, entretanto é de difícil manejo, possuindo diversas problemáticas que interferem durante o ciclo da cultura. O uso de algumas estratégias como a escolha da cultivar mais adaptada para a região, poderá diminuir a probabilidade de perdas e erros ao final do ciclo da cultura. Este trabalho teve como objetivo avaliar adaptabilidade e produtividade de dez cultivares de algodão no município de Confresa - MT. O experimento foi conduzido a campo aberto, utilizando o delineamento inteiramente casualizados, na qual observou-se as seguintes variáveis: produtividade, estande, altura, número de capulhos, número de aborto por planta e números de nó. Os resultados foram submetidos pelo software estatístico SISVAR e comparadas pelo teste de Scott-Knott (p < 0,5). A cultivar que se destacou em termos de produção de pluma foi a IMA 5801 B2RF.

La arqueología histórica, la sociedad, la historia y el estado las relaciones entre la arqueología y antropología urbana
Authors: Volpe Soccorso
Published: August 2021

El registro arqueológico como sabemos no es indicador directo de las actividades cotidianas, se trata de un registro que generalmente es desechado, abandonado o dejo de ser utilizado o reciclado según sea la condición material de dicho registro. De ahí que se utilizan los conceptos de contextos de deposición y contextos socio-culturales. En este caso analizaremos el correspondiente contexto de deposición del sitio popularmente llamado La Basurita, antiguo Vaciadero de Basuras de la ciudad de Rosario. Si bien en este lugar están los desechos producidos por la ciudad entre los años 1870-1890 en el mismo lugar desde la instalación del Vaciadero una numerosa y anónima población vivió e interactuó con los desperdicios ahí arrojados, produciendo modificaciones en el registro ;  que si no tuviéramos en cuenta esta situación podríamos interpretarlos equivocadamente.
