Published: June 2021

Thepiping system is a medium used to convey, distribute, mix, separate, discharge, meter, control or snub fluid flows, and transmit a fluid pressure. The piping system design will have stresses due to thermal and pressure effect. The thermal effect induce pipe expansion. The pipe expansion affect to pipe flexibility, so it is necessary to design an expansion loop. Expansion loop is a method used to increase flexibility in piping systems. This article aims to analyze symmetrical and non-symmetrical in vertical expansion loops whether it can increase flexibility and reduce pipe stress. This article conducts an expansion loop design with 3 trials, namely trial 1 (Vertical Expansion Loop), trial 2 (Nonsymmetrical Vertical Expansion Loop 1), and trial 3 (Nonsymmetrical Vertical Expansion Loop 2). The three trials were compared for flexibility and stress values based on ASME B31.3 requirements. The study results show that all trial 1, trial 2, and trial 3 have good flexibility with a value of 0.00016 because not exceed the requirements of ASME B31.3. The highest design code stress value in trial 1 is 5955 psi (Node A07F), trial 2 is 5906 psi (Node A05F), and trial 3 is 5906 psi (Node A06N). All trials have a code stress not exceeding the allowable stress (20000 psi). So that the symmetrical or nonsymmetrical design of the vertical expansion loop can both increase flexibility and reduce pipe stress.

Authors: Hendryani Atika , Nurdinawati Vita , Dharma Nashrul
Published: June 2021

The regulation and supply of oxygen as one of the medical gases in the hospital is important to ensure the availability of these gases for the survival of patients. The regulation of oxygen gas in hospitals usually uses a piping system with manifolds. The manifold will monitor the oxygen gas pressure on each tube. Manifold systems that are widely used in general can only monitor pressure but cannot perform an automatic exchange on gas cylinders if the pressure is under the permissible conditions. The manifold system design developed is equipped with pressure monitoring for automatic exchange of oxygen gas cylinders using pressure sensors and microprocessors.  The test results of the system using regulator and barometer comparisons showed the percentage value of sensor pressure accuracy of 96.92 percent and 97.16 percent. At pressure below the limit of 285 KPa manifold can perform the exchange of active gas cylinders automatically. These results show the manifold design built can work quite well.

Authors: He Hua , Jia Rui-jing , Dong Kai-qiang , Huang Jia-wen , Qin Zhi-yong
Published: June 2021

A novel biodegradable protein-based material (UMSPIE) that consists of natural polymer soy protein isolate (SPI), ultrasonic-modified montmorillonite (UMMT), and ethylene glycol diglycidyl ether (EGDE) was produced by solution casting. Fourier infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TG), and scanning electron microscopy (SEM) were used to characterize the chemical structure and micro-morphologies of as-synthesized protein-based composite films. The results showed that the interlayer structure of MMT was destroyed by ultrasonic treatment, and the hydrogen bonding between SPI chains and the ultrasound-treated MMT plates was enhanced. The synergistic effect of UMMT and EGDE on SPI molecules made the network structure of the UMSPIE film denser. In addition, the mechanical and barrier properties of the as-synthesized films were explored. Compared with pure soy protein film, the tensile strength of the UMSPIE film has an increase of 266.82% (increasing from 4.4 to 16.14 MPa). From the above, the modified strategy of layered silicates filling combining crosslinking agents is considered as an effective method to improve the functional properties of bio-based polymer composites.

Authors: Gor Chandani P. , Shah Varsha A. , Rangachar Bharadwaj
Published: June 2021

The multiphase induction motor can be a highly preferable choice for the EV application, where the reliability and safety of passengers are one of the major concerns. The main objective of this article is to design high performance fault tolerant control of five phase induction motor (FPIM) drive to enhance the dynamic performance under healthy, faulty and fault tolerant modes of operation under arbitrary open phase fault condition. First, a simple method of modeling open phase fault in any phase of the FPIM drive is proposed. The most frequently occurring open phase faults due to the power electronics switch failure in the inverters are considered for the analysis. A generalized method of modeling arbitrary open phase fault in FPIM drive using back EMF calculations in faulty phase is suggested. The developed method utilizes the same transformation matrix for any open phase fault such that the minimum modification in control strategy is required under fault condition. Thereafter, the control technique is detailed. The rotor field oriented control (RFOC) of FPIM with fuzzy logic speed controller is developed to generate optimal torque reference. The design of FLC is detailed with fine-tuned scaling factor, rule base and membership function to obtain robust performance of the drive under healthy and fault tolerant modes of operation. The complete RFOC scheme for 2 HP FPIM drive is built in MATLAB/SIMULINK incorporating fuzzy logic based controller to verify its performance. The comparison of transient and steady state response and robustness (to the load disturbance as well as fault) obtained using developed fuzzy logic based controller with those using conventional PI controller is presented to prove the efficiency of the suggested controller under various speed torque profiles. The effectiveness of the proposed fuzzy based fault tolerant controller for FPIM drive is validated using OP4510 controller based real time HIL simulator.

Published: June 2021

Objectives

This study aimed to evaluate anxiety and depression in pregnant women during this global disease.

Methods

This was a cross-sectional study recruiting 120 pregnant women. The study was conducted at the outpatient clinic of a tertiary hospital. We recruited women attending for antenatal care. Anxiety was evaluated using an Arabic validated Kuwait University Anxiety Scale (KUAS). Depression was evaluated using a validated Arabic form of the Edinburgh Postnatal Depression Scale (EPDS).

Results

The study included 48 (40%) nulliparous and 72 (60%) multiparous women. The mean KUAS scores for nulliparous and multiparous women were 45.27±10.78 and 47.28±10.62. Both nulliparous and multiparous women had a fairly high possibility of depression. Fifty-three (44.2%) of them reported scores ≥ of 14. Ninety-three (77.5%) women thought that COVID-19 pandemic would affect their pregnancies. There was a significant association between the number of women reporting fear related to the COVID-19 pandemic and their KUAS and EPDS scores (p-value <0.001 each).

Conclusions

COVID-19 affected the mental health of pregnant women to a great extent. Care should be directed to measures that would decrease the impact of this pandemic on vulnerable populations.

Using Belief Function Theory to Assist Pavement Maintenance and Rehabilitation Activities
Authors: Chen Shong-Loong , Hsu Kuen-Jeng , Chang Jia-Ruey
Published: June 2021

Several information technology approaches have been applied to life cycle analyses to improve decision-making performance and prolong infrastructure life spans. Belief function theory (BFT), also known as the Dempster-Shafer theory of evidence, is a method of representing uncertain, incomplete, and imprecise evidence of a system’s knowledge base. BFT has rarely been applied to pavement management until now. For pavement management decision-making, pavement engineers must formulate relationships between various objectives, incorporate subjective judgment, and pool evidence from various sources. These issues are not adequately addressed in the existing analytical tools used in pavement management. This paper conducts a study of pavement maintenance and rehabilitation (M&R) activities using BFT. Questionnaires are carried out to establish an evidential tree, which is used to quantify the level of uncertainty associated with M&R activities. With respect to the given evidence in the case study, the belief interval of (0.222, 0.778) with uncertainty for the M&R activities can be obtained by using Dempster’s rule of combination. BFT provides a more rigorous but straightforward approach to assisting pavement engineers with M&R decision-making.
Troping Time: Refrain Interpolation in Sacred Latin Song, ca. 1140–1853
Authors: Caldwell Mary Channen
Published: June 2021

This article explores a practice in evidence across Europe from the twelfth to the nineteenth century involving the singing of a brief refrain within sacred Latin songs and hymns. Tracing the circulation of the two-part refrain “Fulget dies … Fulget dies ista” across multiple centuries, in both song-form tropes of the office versicle Benedicamus Domino and as a trope interpolated into hymns, I chart its unique movement between genres and in and out of written record. Examining the unusual origins, transmission, and function of the refrain, I begin with its emergence in twelfth-century manuscripts and conclude with its unnotated appearance in nineteenth-century printed Catholic songbooks. I argue that the refrain’s long-standing appeal can be located in its function as a poetic and liturgical trope of time itself. While tropes often enhance the “hic et nunc” (here and now) of the liturgy, the “Fulget dies” refrain gained additional temporal significance through its intimate link to songs of the Christmas season. The “shining day” imagery introduced by the refrain offered a tangible way of marking seasonal time in devotional rites, poetically indexing the light-based symbolism of Christmas, the winter solstice, and the New Year. The inherently temporal meaning of the refrain lent it flexibility as a trope, enabling its movement across genres and liturgies. Integrated into sacred Latin songs, the “Fulget dies” refrain functioned as a pithy musical and poetic commentary on liturgical, calendrical, and seasonal temporalities—in other words, as a trope of time in sacred song.
Development of integrated marketing Internet communications in the activity of Ukrainian banks
Authors:   Ivan Franko National University of Lviv, Demko Mariana
Published: June 2021

In modern conditions the Internet is developing rapidly. Marketing communications on the Internet is one of the main elements of Internet marketing of banking institutions and an important element in establishing relationships with target audiences and managing them, informing customers, improving the image of the bank. It is determined that the Internet today covers the information, communication and logistics areas of marketing communications of banks. The paper identifies the areas of integrated marketing Internet-communications in the activities of banks and their main elements to present their characteristic. At the present stage of development of Internet-communications in activities banking, it is advisable for banking institutions to use advertising, digital and creative strategies. It was found that the current trends in the development of marketing communications on the Internet also indicate the growth of Internet-communications in social networks as an important mechanism for interesting the bank customers and forming interaction with them and the development by the bank of its website, its attractive design, updating information on it. The results of the study showed that the largest share of Internet users in Ukraine uses mobile phones or smartphones, the number of which is growing, which expands the capabilities of banks in the field of Internet-communications. It was established that the most active banks in the media space are banks with state share: JSC CB «PrivatBank», JSC «Oschadbank», JSC «Ukreximbank» and banks of foreign banking groups such as JSC «Raiffeisen Bank Aval», JSC «OTP BANK», JSC «ALFA-BANK». JSC «FUIB» is among the banks with private capital. At the same time, the largest media activity of banks in 2019 was observed in banks of foreign banking groups, and in 2019, 2021 by the number of messages in state-owned banks. The analysis of the collected marketing information showed that the largest number of messages from the leading banks of Ukraine by categories of media was observed in the Internet media, as the Internet is a convenient, cheap and effective communication channel in all areas activities. The expediency of using the Internet to promote banking products is also due to the fact that recently the effectiveness of traditional channels for disseminating information about banks and their products has decreased.

Oxytocin signal contributes to the adaptative growth of islets during gestation
Authors: Gu Ping , Lin Yuege , Wan Qi , Su Dongming , Shu Qun
Published: June 2021

Background

Increased insulin production and secretion by pancreatic β-cells are important for ensuring the high insulin demand during gestation. However, the underlying mechanism of β-cell adaptation during gestation or gestational diabetes mellitus (GDM) remains unclear. Oxytocin is an important physiological hormone in gestation and delivery, and it also contributes to the maintenance of β-cell function. The aim of this study was to investigate the role of oxytocin in β-cell adaptation during pregnancy.

Methods

The relationship between the blood oxytocin level and pancreatic β-cell function in patients with GDM and healthy pregnant women was investigated. Gestating and non-gestating mice were used to evaluate the in vivo effect of oxytocin signal on β-cells during pregnancy. In vitro experiments were performed on INS-1 insulinoma cells.

Results

The blood oxytocin levels were lower in patients with GDM than in healthy pregnant women and were associated with impaired pancreatic β-cell function. Acute administration of oxytocin increased insulin secretion in both gestating and non-gestating mice. A 3-week oxytocin treatment promoted the proliferation of pancreatic β-cells and increased the β-cell mass in gestating but not non-gestating mice. Antagonism of oxytocin receptors by atosiban impaired insulin secretion and induced GDM in gestating but not non-gestating mice. Oxytocin enhanced glucose-stimulated insulin secretion, activated the mitogen-activated protein kinase pathway, and promoted cell proliferation in INS-1 cells.

Conclusions

These findings provide strong evidence that oxytocin is needed for β-cell adaptation during pregnancy to maintain β-cell function, and the lack of oxytocin could be associated with the risk of GDM.

Published: June 2021

Purpose

To evaluate the value of MRI-based texture analysis of extraocular muscle (EOM) and orbital fat (OF) in monitoring and predicting the response to glucocorticoid (GC) therapy in patients with thyroid-associated ophthalmopathy (TAO).

Methods

Thirty-seven active and moderate-to-severe TAO patients (responders, n = 23; unresponders, n = 14) were retrospectively enrolled. MRI-based texture parameters (entropy, uniformity, skewness and kurtosis) of EOM and OF were measured before and after GC therapy, and compared between groups. Correlations between the changes of clinical activity score (CAS) and imaging parameters before and after treatment were assessed. Receiver operating characteristic curves were used to evaluate the predictive value of identified variables.

Results

Responsive TAOs showed significantly decreased entropy and increased uniformity at EOM and OF after GC therapy (P < 0.01), while unresponders showed no significance. Changes of entropy and uniformity at EOM and OF were significantly correlated with changes of CAS before and after treatment (P < 0.05). Responders showed significantly lower entropy and higher uniformity at EOM than unresponders before treatment (P < 0.01). Entropy and uniformity of EOM and disease duration were identified as independent predictors for responsive TAOs. Combination of all three variables demonstrated optimal efficiency (area under curve, 0.802) and sensitivity (82.6%), and disease duration alone demonstrated optimal specificity (100%) for predicting responsive TAOs.

Conclusion

MRI-based texture analysis can reflect histopathological heterogeneity of orbital tissues. It could be useful for monitoring and predicting the response to GC in TAO patients.

Published: June 2021

In order to improve the processing quality of wood parts, an orthogonal experimental design of five factors and four levels was adopted, and a water-jet assisted laser cutting experiment on Korean pine (Pinus koraiensis) was conducted. Moreover, by using range analysis, the influences of the defocusing amount, cutting speed, laser power, water pressure, and water jet angle on the processing quality of Korean pine parts were evaluated, and the optimum process parameters were determined. The test results show that when the defocusing amount was -1 mm, water jet angle was 30°, laser power was 48 W, water pressure was 1.0 MPa, and cutting speed was 25 mm/s, the best processing quality of Korean pine parts was obtained.
Effects of microwave modification on the desulfurization and denitrification of activated coke
Authors: Zhang Junhong , He Zhi-jun , Guo Qing , Xiao De-chao , Zhan Wen-long
Published: June 2021

Microwave modification of activated coke is reported as a green and simple route to improve its synergistic desulfurization and denitrification. The results showed that microwave irradiation improved the specific surface area and pore volume, decreased the pore size, and activated the surface functional groups of the activated coke. Under the conditions of a microwave power of 500 W and a modification time of 30 min, the specific surface area was increased from 185.9 m2/g to 351.7 m2/g, the pore volume increased from 0.042 m3/g to 0.111 m3/g, and the characteristic peak strengths of C=C and -OH drastically increased. When the reaction temperature was 140 °C and the O2 concentration was 10% (by volume), the desulfurization and denitrification efficiency were maintained at levels greater than 90% and 80% for 30 min and 15 min, respectively. The C-O content increased, and the C=C and -OH content decreased after undergoing desulfurization and denitrification. The desulfurization and denitrification products were primarily sulfate and nitrate. This provides theoretical support for the application of microwave modified active coke in low temperature desulfurization and denitrification.
“To See Together Without Claiming to Be Another”: Stories as Relations, Against One-Direction Mode of Indigenous Stories Travelling
Authors: Kim Eun-Ji Amy , Leclaire Sandra-Lynn
Published: June 2021

Once communities’ stories are taken up by researchers and shared within the ivory tower of academia, the stories circulate within the ivory tower. It is often the case that these archived stories from communities are used by researchers, without asking permission from the communities where the stories originate. In this article, we aim to critically review and reflect on underlying theories and practices in conventional Eurocentric academia that allows for a ‘one direction’ mode of storytelling dissemination, allowing researchers to take the ‘version’ of community knowledge and/or stories without seeking the original approval from the communities themselves. We suggest ‘thoughtful’ questions for both settler and Indigenous researchers to consider in hopes of promoting ‘travelling back to original sources’ in their scholarly work.
Ethical Indigenous Economies
Authors: Kelly Dara , Woods Christine
Published: June 2021

In this article, the authors argue that trans-systemic knowledge system analysis of Indigenous-to-Indigenous economics enables generative thinking toward Indigenous futures of economic freedom. The authors apply a trans-systemic lens to critically analyze persistent development philosophy that acts as a barrier to the advancement of Indigenous economic development thinking. By exploring ways in which colonial discourse entraps Indigenous nations within circular logic in service of a normative centre the need for new economic logic is apparent. Shifting to trans-systemic knowledge systems analysis to include diverse insights from Māori and other Indigenous economic philosophy, the authors show that it is not profit and financial growth that matters in and of itself. Rather, according to Indigenous definitions of wealth, economic freedom and development are constituted by value creation that aligns with Indigenous worldviews and principles. Indigenous economic knowledge centred on relationship, reciprocity and interconnectedness fosters Indigenous economic freedom.
Walking Many Paths, Our Research Journey to (Re)present Multiple Knowings
Authors: Hogarth Melitta , Czuy Kori
Published: June 2021

Indigenous peoples globally are seeking new ways in which to communicate and share our worldviews.  Sometimes defined as resistance research, emancipatory research, decolonising research - our research (re)presents the multiple journeys in which we live and come to know. Emerging Indigenous research methodological approaches are centring Indigenous ways of knowing, being and doing, to privilege Indigenous voices that have been suppressed through colonization.  The intricate weaving of Western methodologies with Indigenous knowledges evokes agency in two emerging Indigenous researchers (from Australia and Canada) and weaves a path of reconciliation between their diverse disciplines as well as the seemingly dichotomous knowledge systems they are challenged to work within. Using metalogue, a way of authentically bringing together multiple voices through dialogue, we discuss the creative and radical Indigenous methodological approaches developed and enacted within our PhDs.  The paper will provide insights to the epistemological, ontological and axiological principles that inform emerging Indigenous approaches to research.
A regulamentação das parcerias público-privadas como tática para aprofundar a privatização das universidades federais e do aparato público de ciência e tecnologia no Brasil
Authors: Valdo João Paulo da Silva , Melim Juliana Iglesias , Teixeira Rafael Vieira
Published: June 2021

O presente texto traz reflexões sobre as novas regulamentações que incidem sobre a gestão da educação superior pública e do aparato público de ciência, tecnologia e inovação. Trazemos, neste artigo, parte dos resultados de um estudo documental realizado sobre normas e legislações federais que afetam as universidades federais brasileiras no século XXI. Nosso percurso analítico compreende que os dispositivos legais que regulamentam as parcerias público-privadas, e principalmente o novo Marco de Ciência, Tecnologia e Inovação (Lei n.º 13243/2016), são táticas que aprofundam o processo de privatização da política educacional superior. Esse movimento de contrarreforma do Estado sobre o financiamento impacta na autonomia universitária e altera o papel social desempenhado pelas universidades federais brasileiras, colocando-as ainda mais a serviço do mercado. Por isso, essas modificações ocorridas no século XXI representam o aprofundamento e o aprimoramento da ofensiva neoliberal às políticas sociais, em específico as políticas de educação superior e de ciência e tecnologia.
How does didactic knowledge develop?: Experiences from a design project
Authors: Sloane Peter F. E.
Published: June 2021

We, the authors of the paper, have jointly conducted several design-based research (DBR) projects. The subject of this paper is a project lasting approximately 18 months, which dealt with the introduction of a new curriculum in a vocational college. We were involved in different roles: one as a representative of the research community and the other as a representative of the vocational college and thus of practice. In the project, different interests were considered: the research division wanted to generate knowledge while the practitioners were interested in implementing a curriculum and developing new forms of learning and teaching. It is not that we could always assign each of these two perspectives to exactly one of us, even though we were officially researchers and practitioners. We have always approached each other in our DBR projects.

Both perspectives have been incorporated into the paper: One author is concerned with the genesis of knowledge—how knowledge is created in DBR projects, a partly methodological approach. The other author attempts to find theoretical points of reference and reassurances about the project work. This leads to very practical considerations.

The project did not commence with an exactly defined problem; we began with broad concerns that had to be distilled into specific goals over the course of the project..

We had to conduct dialogical planning in our different roles and responsibilities. After each work phase and workshop, we reviewed and made a record of what had happened and how, the condition of the group and what it should work on in the next practical phase. This was supplemented with classroom visits and one-on-one discussions with various project participants. The information derived from these evaluations was subsequently used in the planning of the next cycle. Therefore, in the next cycle, the same project was not conducted, but a revised project was developed, which continued from where the previous cycle had ended. Thus, the problem definition continued evolving. In this paper, we have tried to concisely present how the work progressed in phases and cycles and roughly described the thought process and evaluations that shaped this project.  Perceived this way, this paper serves two different interests. First, it shows how a problem definition was developed and further sharpened and what concrete result was obtained in the process. This is indicated by the subtitle. Second, it explains how knowledge is created and defines the scope and specificity of this knowledge.
Assessment of reinforced concrete slab of historical structures by the yield-line method
Authors: Mahrouseh Rayan , Orbán Zoltán
Published: June 2021

The study demonstrates and evaluates an approach in the structural analysis phase when assessing reinforced concrete slabs.

Due to different values of a parameter in the tests’ results, 10 models was crated for the first case study and 4 models for the second one.

In order to compare the results in terms of the flexural bearing capacity, the slabs were analyzed by using elastic finite element analysis and yield-line analysis.

Comparing the results shows that minor modification in the parameters associated with bearing capacity and the boundary conditions can affect the adequacy factor considerably, while the parameters those relate to boundary conditions affect the distribution of the yield lines.

The COVID-19 has spread worldwide and become an international pandemic. The promising target for drug discovery of COVID-19 was SARS-CoV-2 Main Protease (Mpro), that has been successfully crystallized along with its inhibitor. The discovery of peptide-based inhibitors may present better options than small molecules for inhibitor SARS-CoV-2 Mpro. Natural compounds have such a wide potential and still few explored, Zizyphus spina-christi is one of the medicinal plants that have many pharmacological activities and contains a peptide compound from alkaloids class, i.e. cyclopeptide alkaloids, that is interesting to explore as SARS-CoV-2 Mpro inhibitor. The compound structure was drawn and optimized using density functional theory 3-21G method. The protein chosen was the high resolution of SARS-CoV-2 MPro receptor (1.45 Å) with PDB ID: 6WNP, in complex with boceprevir. Molecular docking simulation was performed using Autodock4 with 100 numbers of GA run, the validation methods assessed by RMSD calculation. Furthermore, the prediction of pharmacological activity spectra was carried out using the PASS Prediction server. The results showed RMSD value was 1.98 Å, this docking method was valid. The binding energy of all compounds showed better results than the native ligand (Boceprevir). The in silico PASS prediction results indicated that all compounds showed antiviral activity. Some compounds showed protease inhibitory activity, i.e Ambiphibine-H, Franganine, and Mauritine-A, and the highest Pa (Predicted activity) value showed by Mauritine-A compounds. It can be concluded that the cyclopeptide compounds of Zizyphus spina-christi were indicated to have a potential as COVID-19 therapy targeting SARS-CoV-2 Mpro.

Tecnologías para una sociedad abierta posthumana
Authors: Bengoetxea Juan Bautista
Published: June 2021

Resumen: El texto se divide en dos partes. En la primera presento el desarrollo del cíborg como entidad cultural y tecnológica examinada desde el prisma de la teoría de la mente, donde se subraya la importancia de diversos elementos ficcionales y reales. En la segunda parte reflexiono acerca del futuro que la sociedad tecnológica y cíborg puede deparar al ser humano. En particular, mi objetivo es mostrar que los seres posthumanos constituyen una realidad ya establecida que exige una reflexión de índole moral y social que apunte al papel de los expertos en relación con las necesidades de los ciudadanos no-expertos. La conclusión final aboga por la constitución de normas y regulaciones que permitan encauzar los avances tecnológicos posthumanos en concordancia con éticas aplicadas a los humanos.
Macrozoobenthos in an altitudinal gradient in North Patagonian Cautín River (Araucanía Region, Chile)
Authors: Figueroa D. , Rios-Escalante P. De los
Published: June 2021

Abstract The Cautín River is closely related with the economic development of Temuco city, (38°S; Chile). Existing knowledge of the Cautín River is limited to information about its biological characteristics as a reference for the evaluation and assessment of water quality. The object of this study was to develop taxonomic characterisation of the benthic macroinvertebrates along the main course of the Cautín River, and to study the community structure using correlation analysis between community parameters. To carry out this research, the macroinvertebrate community was studied in 10 sampling sites distributed along the main course of the river. The samples were taken in summer (1997 and 2000), when optimal hydrological conditions existed. Analysis of the samples showed that the benthic fauna was composed of 56 taxa, the dominant group being insects with 48 taxa. Three main sectors were recognised in the course of the Cautín River: high, middle and low. Each sector has restricted-distribution species, while other species are widely distributed along the river. These distribution patterns seem to be influenced by dissolved oxygen concentration, temperature, altitudinal distribution and anthropo-cultural activity, present at every sampling site. Finally, this research provides a first approach to the biology of the Cautín River. Further studies could be planned on the basis of this knowledge to investigate water quality indicators based on macroinvertebrate communities.
Breeding and reproductive behaviour of the neo-tropical opossum, Didelphis marsupialis insularis, Allen 1902 under captive conditions
Authors: Tardieu L. , Garcia G. W.
Published: June 2021

Abstract Developing a captive breeding system for the widely hunted Caribbean species of opossum Didelphis marsupialis insularis can greatly aide in the management and conservation of this species in the neo-tropics. Although this species possesses ideal traits for captive breeding in this region (tolerance to high heat and humidity, high reproductive rate, and resistance to disease), challenges due to its aggressive behaviour and limited information on its breeding behaviour have prevented a system from being developed for this species. The present study describes a breeding system, and the reproductive behaviour of this species under captive conditions. Six (1 male; 5 females) adult opossums were maintained and managed for breeding over a ten (10) month period. Pouch litter sizes averaged 5±2.5 with a range of 2 to 8. Gestation length was found to be 13.25±0.96 days and 4 litters (n=23) were successfully weaned at 11-13 weeks. It was found that the male D. m. insularis exhibits behaviours of interest that can serve as indicators for receptivity of the female, and overall, that this species can be successfully reared and bred under captive conditions in the neo-tropics.
