Authors: Karolan Karmanis
Published: November 2022

Indonesia as a democratic country has entered the era of the millennium in the implementation of general elections simultaneously, it is necessary to utilize computer technology using the Electronic-Voting (E-Voting) method. Several regions in Indonesia have used the E-Voting method as a means of democracy which is applied at the hamlet and village head election levels. Village Head election policy with E-Voting as a new means of democracy through a touch of the monitor screen and E-Verification through voters' E-KTP. For example: Pemalang Regency (Ujunggede Village), Jembrana Regency in Bali (Mendoyo Dangin Tukad Village). Elections through e-voting must be designed as best as possible to realize the principles of direct elections, namely direct, general, free, secret (overflow) and honest and fair (fair) in direct elections. Electronic voting systems (e-voting) must be taken seriously and ensure transparency, certainty, security, accountability, and accuracy. In addition to technology readiness, of course, it must be supported by the readiness of the community in implementing this e-voting system in the future. The government's unpreparedness and lack of socialization of e-voting can also be a factor triggering failure in implementing this system.

Published: November 2022

This research is motivated by an increase in investment, gross domestic product, government expenditure, and wages but does not cause an increase in employment. This study aimed to analyze the effect of independent variables on employment-based low and high education. The novelty of this research is to use the binary logistic regression method. The data used is secondary data province in Indonesia. The analysis results show that gross domestic product and wages have more influence on the employment of highly educated workers. Domestic investment has a significant negative effect on employment. So that domestic investment has more influence on the employment of low-educated workers. The recommendation from this research is that the government must pay attention to workforce education to keep up with the times. The limitation of this study is that there are empty data in the province of North Kalimantan.

Facilitating learners’ participation through classroom translanguaging: comparing a translanguaging classroom and a monolingual classroom in Chinese language teaching
Authors: Nie Mengjun , Lu Juexuan , Zheng Yongyan , Shen Qi
Published: November 2022

Translanguaging practices in Chinese as a second language (CSL) classrooms have been a heated topic in recent years, despite the longstanding Chinese-monolingual ideology. Against this backdrop, we have explored the functions of translanguaging practices in CSL classroom and the interplay of translanguaging and learners’ participation, by comparing the language practices of a translanguaging-oriented classroom and a Chinese-monolingual classroom. We found the functions of classroom translanguaging include meaning-negotiation, peer-assisting, efficiency-increasing and communication encouraging. The findings also reveal that although multilingual practices can also be found in the Chinese-monolingual classroom, they are characterized by a norm-conforming pattern, in contrast to the norm-breaking pattern in the translanguaging-oriented classroom, and the latter can empower students and motivate them to become engaged in Chinese learning. Moreover, multilingual practices deliberately adopted by teachers can be regarded as pedagogical translanguaging and facilitate learner engagement only when there exists no discrepancy between their pedagogical ideology (i.e. advocating translanguaging) and practices. Based on our findings, we advocate a reflection and adjustments to the current monolingual policy in CSL classroom.
My scientific genealogy and the Toronto ACDC Laboratory, 1988–2022
Authors: Diamandis Eleftherios P.
Published: November 2022

There is a saying that as people get older, they prefer to speak more about the past and less about the future. As I go through the last chapter of my scientific career, which spans from 1988–2022, I traced my scientific genealogy and the most important scientific achievements of my laboratory. By examining close to 1,000 PubMed-indexed papers published, I found out that none of them describes best our most important contributions. Also, by realizing that our contributions in science would have likely been discovered by others shortly afterwards, I focused my attention to other metrics. I suggest here that the best metric of success is the number of people that have been trained in my lab, and found their own way in their professional and other endeavors. Over the years, I trained over 250 individuals, of which 49 obtained a PhD, 19 an MSc, 37 were post-doctoral fellows, 5 were clinical fellows and about 150 were co-op/undergraduates and summer students. Many of these individuals now hold important positions in Academia, Government and Industry. My graduates, who have now created their own genealogy and many more individuals with roots to my laboratory, are now serving the society. In conclusion, I consider the development of young trainees as my most important career contribution.

Authors: Mohd Faizal Azrul Nurfaiz , Che Yunus Mohd. Azizi , Ali Asmadi , Zaini Muhammad Abbas Ahmad
Published: November 2022

The exclusive properties of β-cyclodextrin (β-CD) combined with its harmless characters making it as an interesting and potential carbon adsorbent for water pollutants removal via adsorption. This work was aimed at evaluating the kinetics and isotherm parameters of methylene blue dye adsorption onto β-CD polymers. The carbon polymers were prepared by citric acid cross-linking, followed by post-treatment with sodium p-toluenesulfinate. The adsorbents were characterized using TGA, BET and FTIR. The adsorption of methylene blue was studied at varying concentrations (5–300 mg/L) and contact times (10–2880 min), and the kinetics and isotherm models were employed to describe the adsorption data. The post-treated carbon polymer exhibits a greater specific surface of 16.6 m2/g. The maximum adsorption of methylene blue by cross-linked and post-treated β-CD adsorbents are 263 and 227 mg/g, respectively. The kinetics data fitted well into pseudo-first order model, indicating physical adsorption. The Boyd’s model showed that film diffusion may be the controlling mechanism. The equilibrium data of methylene blue adsorption for the two β-CD polymers obeyed Langmuir model. To conclude, β-CD is a promising adsorbent candidate for the treatment of dye wastewater.
Sovereign Debt Restructuring: The Way Forward
Authors: Xafa Miranda
Published: November 2022

The timely and orderly resolution of sovereign debt crises has long been a key challenge facing the global financial architecture. The framework for crisis resolution evolved in response to the capital account crises of the 1990s (Mexico, Russia, Southeast Asia), the Argentine crisis of 2001 and its aftermath, and the Global Financial Crisis of 2008–9 which morphed into the Euro area debt crisis of 2010–12. Efforts to expedite crisis resolution involved a two-pronged approach, one focusing on IMF policies and lending facilities and the other on ways to overcome the collective action problems involved in restructuring securitized debt. This paper examines these efforts in the context of the crises that triggered them and provides some guidance for the future. It argues that the way forward involves action on several fronts, including restoration of the essential principle that IMF programs should aim at reaching a manageable debt position within the program period with a high probability.
Racial discrimination among children in the United States from 2016 to 2020: an analysis of the National Survey of Children’s Health
Authors: Elenwo Covenant , Hendrix-Dicken Amy , Lin Vanessa , Gatewood Ashton , Chesher Tessa , Escala Michelle , Hartwell Micah
Published: November 2022

Context

Sociological research has linked racism and discrimination among children to poorer health outcomes and social conditions later in life.

Objectives

Given the change in the political climate in the United States, highly publicized deaths of Black men and women by police, and the rise in hate crimes against Asian Americans from 2016 through 2020, our primary objective was to assess trends in racial or ethnic discrimination among children in the United States.

Methods

We conducted a cross-sectional analysis of the National Survey of Children’s Health (NSCH), a nationally representative survey, utilizing data from 2016 to 2020. We calculated yearly population estimates of whether a child had experienced discrimination based on race/ethnicity via a parent-reported item. We further divided the estimates by race/ethnicity and plotted linear trends over time.

Results

Data from the NSCH show that racial/ethnic discrimination reported by parents of children who are minorities increased from 6.7% in 2016 to approximately 9.3% in 2020. Indigenous children were reported to experience discrimination at high rates ranging from 10.8% in 2016 to 15.7% in 2020, as well as Black children ranging from 9.69% in 2018 to 15.04% in 2020. The percent of Asian, Hawaiian or Pacific Islander, and Hispanic children reported to have experience discrimination was between 4.4 and 6.8% during this time.

Conclusions

Discrimination negatively impacts the developmental experiences of children, disproportionately affecting those identifying as Indigenous and Black. Therefore, addressing harmful stereotyping of Indigenous and Black cultures is necessary, especially in media targeted toward children. Providing culturally competent healthcare, critically in the Indigenous and Black pediatric population, may improve long-term outcomes by reducing discriminatory barriers to healthcare access.
Fighting the COVID-19 pandemic with words: an investigation of pragmatic presuppositions in Chinese anti-pandemic slogans
Authors: Mo Junhua , Heng Renquan
Published: November 2022

Slogans play an important role in Chinese society. Numerous slogans have been created and used in the fight against the COVID-19 pandemic. As an eye-catching linguistic phenomenon, anti-pandemic slogans have sparked heated debates not only among the general public, but also in the academic sector. This study is focused on the pragmatic presuppositions in Chinese anti-pandemic slogans. By adopting a mixed approach (quantitative and qualitative), it finds that six types of pragmatic presuppositions are used in Chinese anti-pandemic slogans. Among them, the behavioral presuppositions rank first in frequency of use, factive presuppositions second, stative presuppositions third, belief presuppositions fourth, cultural presuppositions fifth and emotional presuppositions sixth. The pragmatic presuppositions of these slogans can serve four major functions, which are persuading people to act properly, spreading scientific knowledge, warning people against wrongdoings and bolstering people’s confidence. However, there are sporadic occurrences of misusing pragmatic presuppositions in the so-called “hardcore” slogans. This study concludes that knowledge of pragmatic presuppositions is essential to a correct understanding and a proper creation of Chinese anti-pandemic slogans.

Published: November 2022

Bacterial sialidases are enzymes that are involved in a number of vital processes in microorganisms and in their interaction with the host or the environment. Their wide application for scientific and applied purposes requires the search for highly effective and non-pathogenic producers. Here, we report the first description of sialidase from Oerskovia paurometabola. The extracellular enzyme preparation was partially purified. The presence of sialidase was confirmed in native PAGE treated with the fluorogenic substrate 4MU-Neu5Ac. Maximum enzyme activity was registered at 37 °C and in the pH range of 4.0–5.5. The influence of metal ions and EDTA was examined. It was demonstrated that EDTA, Mn2+ and Ba2+ ions inhibit the sialidase activity to different extent, while Cd2+, Fe2+ and Fe3+ have stimulating effect on it. These features are studied for the first time concerning sialidase of Oerskovia representative. Cell bound sialidase and sialate aldolase were also established.
Comparative Environmental Analysis for Using Waste Polyethylene and Steel Slag in Semi-dense Asphalt Pavements
Authors: Piao Zhengyin , Mikhailenko Peter , Kakar Muhammad Rafiq , Hellweg Stefanie , Poulikakos Lily D.
Published: November 2022

This study presents a life cycle assessment (LCA) evaluating the use of virgin materials, waste polyethylene (PE), and electric arc furnace steel slag (EAFSS) in semi-dense asphalt (SDA) surface courses, which is primarily used for low-noise pavements. Three types of SDA mixtures with virgin materials, waste PE, and EAFSS were prepared and water sensitivity tests were conducted to determine the mechanical performance. The LCA defined three scenarios using system expansion, namely (1) the reference scenario using virgin materials in SDA and disposal of waste PE and EAFSS by municipal solid waste incineration (MSWI) and landfill, respectively; (2) the test scenario using waste PE and straight run binder in SDA, with landfilling of EAFSS; (3) the test scenario using EAFSS in SDA, with the disposal of waste PE by MSWI. The data from the experiments, Swiss industries, official reports, and standard databases were used for the inventory analysis. The results show that compared to the reference, the scenarios using waste PE and EAFSS in SDA would reduce 15 % and 36 % of greenhouse gases emissions, respectively. The reason for the improved environmental performance when waste PE is used in asphalt can be attributed to the use of straight run binder to replace polymer-modified binder and the avoided MSWI. For the EAFSS scenario, the improved environmental performance is attributable to the avoided landfilling. The results also indicate that the recycling of waste PE and EAFSS in SDA would not have benefits in nonrenewable cumulative energy demand.

Published: November 2022

Fatigue and rutting are the most studied pavement distresses. There are different material testing protocols whose compatibilities must be systematically analyzed for proper material selection and performance prediction. They usually focus on either rutting or on the fatigue susceptibility of the materials. In asphalt binders, the idea is to assess material behavior that may relate to the behavior of the corresponding asphalt mixtures in the field. However, a new multiple stress creep recovery (MSCR) approach suggests the use of an index obtained from a modified testing protocol (B-index) that may relate to fatigue. This paper compares the parameters obtained by a new MSCR test methodology, which gives parameters that may also relate to fatigue, with parameters from the standard MSCR test and linear amplitude sweep (LAS) test to analyze both binder permanent deformation and fatigue cracking. This study was conducted with a PG (Performance Grade) 64-28 neat binder and three levels of styrene-butadiene-styrene (SBS) modification by weight of the binder: 2 %, 3 %, and 4 %. The results from the new MSCR protocol indicates that the higher the modifier content, the higher the fatigue resistance based on the B-index. This finding is also supported by the LAS parameters, fatigue area factor of binder (FAFB) and af (fracture length). The study concluded that a preliminary choice based on MSCR’s B-index might overcome time-consuming testing.
In silico Design of a Crimean-Congo Hemorrhagic Fever Virus Glycoprotein Multi-Epitope Antigen for Vaccine Development
Authors: Mears Megan C. , Bente Dennis A.
Published: November 2022

Objective:

No licensed vaccine is available to prevent the severe tick-borne disease Crimean-Congo hemorrhagic fever (CCHF), caused by the CCHF virus (CCHFV). This study sought to show that a combination of computational methods and data from published literature can inform the design of a multi-epitope antigen for CCHFV with immunogenic potential.

Methods:

Cytotoxic and helper T-cell epitopes on the CCHFV glycoprotein precursor (GPC) were evaluated with bioinformatic servers. These data were combined with work from previous studies to identify potentially immunodominant regions of the GPC. Regions of the GPC were selected for generation of a model multi-epitope antigen in silico, and the percentage residue identity and similarity of each region were compared across sequences representing the widespread geographical and ecological distribution of CCHFV.

Results:

Eleven multi-epitope regions were joined with flexible linkers in silico to generate a model multi-epitope antigen, termed EPIC, which included 812 (75.7%) of all predicted epitopes. EPIC was predicted to be antigenic by two independent bioinformatic servers, thus suggesting that multi-epitope antigens should be explored further for CCHFV vaccine development.

Conclusion:

The results presented herein provide information on potential targets within the CCHFV GPC for guiding future vaccine development.
Cyclin-Dependent Kinase 5 Regulates cPLA2 Activity and Neuroinflammation in Parkinson’s Disease
Authors: Paul Sangita , Fatihi Saman , Sharma Srishti , Kutum Rintu , Fields Raymond , Pant Harish C. , Thukral Lipi , BK Binukumar
Published: November 2022

Hyperactivation of cyclin-dependent kinase 5 (Cdk5) by p25, contributes to neuroinflammation causing neurodegeneration in Parkinson’s disease (PD) and Alzheimer’s disease. However, the mechanism by which Cdk5 induces neuroinflammation in the PD brain is largely unexplored. Here, we show that Cdk5 phosphorylates cytosolic phospholipase A2 (cPLA2) at Thr-268 and Ser-505 sites lead to its activation and generation of eicosanoid products. Mutational studies using site-directed mutagenesis and molecular simulations show that the architecture of the protein changes on each single-point mutation. Interestingly, double mutations also led to a severe decline in the activity of cPLA2 and to the disruption of its translocation to the plasma membrane. Further, the brain lysates of transgenic PD mouse models show hyperactivation of Cdk5, resulting in enhanced phosphorylation of Thr-268 and Ser-505 of cPLA2 and its heightened activity, confirming the findings observed in the cell culture model of PD. These phosphorylation sites of cPLA2 and Cdk5 could be explored as the future therapeutic targets against neuroinflammation in PD. Further, conjoint transcriptomic analysis of the publicly available human PD datasets strengthens the hypothesis that genes of the arachidonic acid, prostaglandin synthesis, and inflammatory pathways are significantly upregulated in the case of PD patients compared with that of healthy control subjects.

TiO2 nanotubes were prepared by hydrothermal method using P25 as raw material. The effect of hydrothermal duration and calcination temperature on the crystal structure and morphology of intermediate product and TiO2 was investigated by XRD, SEM and TEM. The photocatalytic activity of TiO2 was evaluated by the degradation of methylene blue. The result revealed the formation process of nanotube and indicated that the photocatalytic activity of TiO2 nanotubes strongly depended on the calcination temperature. The crystallinity of nano-TiO2 was gradually improved with the increasing calcination temperature up to 750 oC resulting in the increase of degradation rate of methylene blue. With further increase in calcination temperature, anatase TiO2 began to transform into rutile phase and the nanotubes completely transformed to particles, leading to the decrease of photocatalytic activity. It was found that TiO2 annealed at 750 oC showed the highest degradation rate, resulting from the excellent crystallinity of anatase phase and nanorod structure.

Objective: to analyze factors related to health behaviors among young students during the pandemic of COVID-19. Methods: cross-sectional study conducted with 282 students aged 18 to 24 years from the Federal Network of Vocational and Technological Education. An electronic form and the Adolescent Health Promotion Scale (Brazilian version) instrument were applied for statistical analysis and multiple linear regressions were used. Results: the overall mean of the scale was 3.29 (Standard deviation (SD)=0.56); the subscales ranged from 2.40 (SD=1.0) physical exercise to 3.76 (SD=0.80) valuing life. We identified that the subscale physical exercise and some items of the subscales social support and responsibility for health presented scores below the mean. Conclusion: according to the theoretical model tested, students in technical courses showed a statistically significant negative relationship in the scores of the general health promotion scale. The subscales of social support, responsibility for health and physical exercise showed statistically significant relationships in relation to the variables gender, age group, family income, level of education and health problem. Contributions to practice: nurses should know the factors related to health behaviors among young students to expand and guide actions, contributing to the improvement of student assistance and care for young people.

Published: November 2022

El estudio de las redes de interacción mutualista es fundamental porque permite conocer las especies que se relacionan al considerar los análisis de sus dietas y al evaluar el efecto de las perturbaciones de un ecosistema. Para una reserva es importante reconocer estos fenómenos, pues evidencian si los esfuerzos de conservación han sido efectivos. Este trabajo se desarrolló en los años 2014 y 2017 en la vereda Playa Güío del municipio de San José  el Guaviare, Colombia. Para conocer la amplitud del nicho y el solapamiento de dietas se calculó el índice de Levins y el índice de Morisita respectivamente. Usando la modularidad, la robustez y el anidamiento (NODF), se analizaron las redes de interacción. Se registraron 18 especies de murciélagos frugívoros y 20 especies de plantas pertenecientes a las familias Piperaceae, Urticaceae, Moraceae, Hypericaceae y Solanaceae. El índice de Levins demostró que las especies de murciélagos prefieren un recurso, mientras que el índice de Morisita evidencia un traslape en las especies frugívoras nómadas y las sedentarias. El anidamiento y la robustez disminuyeron en 2017 ya que aumentó el número de especies, mientras que la modularidad aumentó. La vereda Playa Güío mantiene una red de interacción con especies generalistas asociadas a procesos de regeneración natural importantes para los objetivos de conservación de la reserva, además, las métricas calculadas indican que esta red de interacción mutualista es estable y se puede mantener en el tiempo.

Published: November 2022

La fibra de la palma de iraca es usada como materia prima en la elaboración de múltiples artesanías incluyendo el sombrero de Panamá, razón por la cual es importante estudiar factores que contribuyan a la germinabilidad de las semillas, útiles en su propagación. El objetivo de esta investigación fue evaluar la capacidad de germinación de las semillas en condiciones in vitro y ex vitro procedentes de dos estadios de madurez de infrutescencias de Carludovica palmata. Los porcentajes de germinación se evaluaron mediante cuatro protocolos de desinfección, dos estados de madurez de las infrutescencias en condiciones in vitro, tres concentraciones de ácido giberélico (GA3) en condiciones ex vitro y dos in vitro y finalmente cuatro sustratos de germinación, turba, tierra, tierra-turba y medio MS. Las semillas provenientes del estado de madurez E1, presentaron un menor porcentaje de germinación (17,95 %) comparado con las semillas provenientes de las del estado E2 (86,84 %) (P < 0,05), lo que determinó el uso de este estado de madurez en los experimentos posteriores. Por otra parte, se determinó que las semillas germinan eficientemente en condiciones in vitro en medio semisólido MS, obteniendo un porcentaje de germinación del 88,2 %, muy superior al obtenido con sustratos convencionales (P < 0,05), evidenciando así que este método es muy eficiente para la multiplicación de palma de iraca y puede ser usado en la producción a gran escala de plántulas de este cultivo.

The courtship call of Bokermannohyla ibitiguara (Anura: Hylidae) and details of its mating behavior
Authors: Nali Renato Christensen , Turin Rubens Antonio Felipe , Prado Cynthia Peralta de Almeida
Published: November 2022

Complex courtships have been described for neotropical frogs, but detailed quantifications of calls emitted during this behavior are still rare. Herein, we describe the courtship call of Bokermannohyla ibitiguara, a gladiator tree frog from the Brazilian Cerrado, as well as the female behavior during courtship, and the clutch characteristics. Moreover, we statistically compare the acoustic parameters of the advertisement and courtship calls. We observed that the female also touches the male during courtship and that the courtship call is overall similar to the long note of the advertisement call. However, we uncovered significant differences in frequencies and pulses between these two call types emitted by the same male. This ability to modify call parameters is consistent with previous results in aggressive contexts and reinforces sexual selection as a strong mechanism shaping call variation in this species. This is the third courtship call described for the genus and we emphasize that the description of rare behaviors, even in artificial conditions, is important to advance the field of behavioral ecology across taxa.

Published: November 2022

Rhodothamnus sessilifolius is a species of the Ericaceae family endemic to the Artvin province in NE Turkey. This is in the critically endangered species list and current populations are decreasing, therefore, it requires protection and reproduction. Thus the present study aimed to investigate the effect of various gibberellic acid (GA3) applications on germination of the R. sessilifolius seeds. The effects of various GA3 concentrations on final germination percentage, mean germination time, germination value, and germination rate were analyzed in a growth cabinet. The study demonstrated that gibberellic acid application positively affected germination. Seed percentages of germination were 2.22 %, 18.89 %, 17.78 %, and 15.56 % in the control group for 100, 500 and 1000 ppm GA3 concentrations, respectively. First germination was observed in seeds treated with GA3 after 11 days. There were significant differences (P < 0.05) between all measured germination properties. These results are promising for future conservation strategies.

Published: November 2022

Amphisbaena mertensii is a worm lizard species from South America. Because of its subterranean lifestyle,data on its biology are scarce. In this paper, we present the first record of A. mertensii as prey of a bird, the wood rail Aramides cajaneus. We also review the geographic range of this species, reporting it for 114 localities from west-central Brazil to northeastern Argentina. We update the range of precloacal pores in A. mertensii from 5–8 to 4–8, and report the largest individual of this species with a 458 mm snout-vent length.

Authors: Gantiva Quintero Carlos Hernán , Andrade Correa Miguel Gonzalo
Published: November 2022

Colombia, con 3642 especies de mariposas, es uno de los países que más riqueza de estos organismos expresa a nivel mundial, sin embargo, en regiones con una alta tasa de transformación del paisaje y de fragmentación del hábitat como la Orinoquía, el estudio de estos insectos se ha enfocado en inventarios locales. Este trabajo aporta una primera lista de especies de mariposas en la Orinoquía Colombiana para las familias: Hesperiidae, Papilionidae, Pieridae, Nymphalidae, Riodinidae y Lycaenidae. Con el fin de visualizar a la Orinoquía como una región más allá de las llanuras y para evitar sobreestimación causada por la inclusión de taxones andinos, la biorregión fue dividida en cinco subregiones. A partir de esto, se revisó el material depositado en seis colecciones, literatura asociada y se realizaron salidas de campo. Se obtuvieron 7828 registros correspondientes a 1115 especies desde el año 1941 hasta el 2018, albergando el 30,61 % de la riqueza estimada para el país y próxima a la dada en regiones como la Amazonia con 1088 especies y el Chocó-Darién con 970. Nymphalidae es la familia más rica con 389 especies y el Piedemonte es la subregión con más especies con 829. Este trabajo visualiza a la Orinoquía como una región diversa en mariposas y es un importante aporte al conocimiento de la riqueza de estos insectos en Colombia para la creación de estrategias de conservación y gestión de su conocimiento en esta región.
First report in Colombia and diagnosis of Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae), a parasitoid wasp of Diaphorina citri(Hemiptera: Liviidae)
Authors: Kondo Takumasa , Woolley James B. , Arciniegas Kelly Tatiana , Campos-Patiño Yenifer
Published: November 2022

Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) is herein reported for the first time from Colombia based on specimens collected in the municipality of Palmira, department of Valle del Cauca. Adult male and female wasps of this endoparasitoid are diagnosed based on published literature and character states taken from specimens collected in the present study. The adult parasitoids were extracted from parasitized nymphs (mummies) of the Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae). Information is provided on the differences in the morphology of parasitized nymphs of D. citri with exit holes made by the two main primary parasitoids, i.e., Tamarixia radiata (Hymenoptera: Eulophidae) and D. aligarhensis. Rates of parasitization on D. citri ranged from 1.5 to 24.2 % for T. radiata and 0.3 to 1.0 % for D. aligarhensis. With the present study, the presence of D. aligarhensis in Colombia becomes the second confirmed report of the species in South America, after Ecuador.
Variation in the population density of the Giant African Snail (Lissachatina fulica) in the Neotropical region
Authors: Patiño Montoya Angie , Giraldo López Alan , Tidon Rosana
Published: November 2022

The Giant African Snail (Lissachatina fulica) is one of the 100 world’s worst invasive species and has been recorded in the Neotropical region since the 1980s. Temperature and precipitation variables affect snail population density; however, these relationships have not been investigated for L. fulica on a regional scale. Here, we made the first description of variation in population density of L. fulica in the Neotropical region using a literature search, descriptive statistics, and a Principal Component Analysis (PCA). We found 22 studies covering 36 localities in six countries. The mean snail density was 11.55 ± 28.32 ind/m2, with the lowest value recorded in Cuba (0.0002 ind/m2) and the highest value recorded in Venezuela (150 ind/m2). These values were recorded between 21 % to 93 % of Human Footprint, 710 mm to 4438 mm of Annual Precipitation, 13 ºC to 27 ºC, Mean Temperature of the Coldest Quarter, and 3 ºC to 40 ºC of Temperature Seasonality. The PCA suggested that low densities can occur in various environmental conditions, whereas medium and high densities seem to appear in more specific climatic combinations. In conclusion, increased densities of Lissachatina fulica in the Neotropics seem to be influenced by climatic variations, especially the Mean Temperature of the Coldest Quarter and Annual Precipitation, supporting previous findings in the literature regarding the snail establishment. Future monitoring of this invasive species, performed at expanded spatial and temporal scales, may provide tools to establish a relationship between snail density values and impact.

Published: November 2022

This paper presents a general model for the design to obtain the thickness and reinforcing steel areas of rectangular footings that support from 1 to “n” columns aligned on a longitudinal axis. The pressure diagram is considered linear. Some recently published papers are restricted to certain types of footings as the rectangular isolated footings, and rectangular combined footings that support two columns. The first part of this paper shows the minimum soil area that supports 1 to “n” columns aligned on a longitudinal axis. Three numerical examples are presented for design of rectangular footings subjected to an axial load and two orthogonal moments in each column that supports one, two and three columns. The main advantage of this document over other documents is: this model can be applied for one or more columns supported on a rectangular footing (unrestricted on its sides, one side restricted and two opposite sides restricted).

This study aimed to evaluate the influence of cladode pruning on apical dominance in the production and post-harvest of pitaya fruits. The experiment was carried out at the Sítio das Pitaya do Pará, which is in the city of Tomé-Açu, State of Pará, Brazil. A randomized block design (RBD) in a 3 x 2 factorial scheme was used, with four replications for each treatment. Treatments consisted of three stand positions in the field (beginning, middle, and end of row) and two pruning regimes (with and without pruning). The interaction of factors Pruning and Stand position (P*SP) inhibited sprouting, while the Pruning factor provided heavier fruits and with a better pulp/peel ratio. Thus, cladode pruning provided benefits to plant management, production parameters, and post-harvest quality.
