Modified who tunnel test for high through put evaluation of insecticide-treated nets considering the effects of hosts, exposure time and mosquito density
Authors:   , Kamande Dismas
Published: November 2023

The standard World Health Organization (WHO) tunnel test is a reliable laboratory bioassay used for "free flying" testing of Insecticide Treated Net (ITN) bio-efficacy. Multiple parameters affect the outcomes measured in tunnel tests. Therefore, a comparison of hosts, exposure time, and mosquito density against the current gold standard test (100 mosquitoes, animal bait and 12-hours exposure) was conducted following ITNs evaluation guidelines. A series of experiments were conducted in the WHO tunnel bioassay to evaluate the bio-efficacy endpoints, mortality at 24- hours (M24) and 72-hours (M72), blood feeding success (BFS), and blood feeding inhibition (BFI). The following parameters were evaluated: 1) baits (rabbit, membrane, human arm), 2) exposure time in the tunnel (1-hours vs 12-hours), and 3) mosquito density (50 vs 100 mosquitoes per test). Finally, an alternative bioassay using a membrane with 50 mosquitoes was compared to the gold standard bioassay. Resistant Anopheles arabiensis and susceptible Anopheles gambiae were used to evaluate Interceptor® and Interceptor®G2 ITNs. Similar trends in mortality and BFI were observed for both ITNs using the gold standard WHO tunnel test or alternative bioassays. Mortality and BFS were not statistically different when rabbits were the bait or when 50 or 100 mosquitoes of either strains used. No systematic difference was observed for the agreement by Bland and Altman's methods (B&A) with a mean difference 4.54% in blood feeding and 1.71% for M72. When comparing membrane with 50 mosquitoes and rabbit with 100 mosquito, no systematic difference was observed for the agreement with mean difference 9.06% for blood feeding and -5.44% for M72. These results demonstrate that WHO tunnel tests using rabbit bait run with 50 mosquitos’ measures similar outcome compared to gold standard bioassay. In addition, using a membrane feeder with 50 mosquitoes is a potential replacement for the WHO tunnel bioassay with animal bait and merits further studies at other laboratories to corroborate these findings.
Mixed method study to evaluate factors associated with discarding of long-lasting insecticidal nets in Bagamoyo, Tanzania
Authors:   , Madumla Edith
Published: November 2023

Between 2000 and 2019, more than 1.8 billion long-lasting insecticidal nets (LLINs)were distributed in Africa. While the insecticidal durability of LLINs is around 3 years, nets are generally discarded 2 years post-distribution. This study investigated the factors associated with the decision of users to discard LLINs. A mixed-methods sequential explanatory approach using a structured questionnaire followed by focus group discussions (FGDs) was used to collect information on experiences, views, reasons, how and when LLINs are discarded as well as gather knowledge on net care and repair from the participants. Out of 6,526 households that responded to the questionnaire of LLINs durability trial, 160 households were randomly selected from the households in four villages in Bagamoyo Tanzania for FGDs but only 155 households participated in the FGDs. Five of the household representatives couldn’t participate due to unexpected circumstances. A total of sixteen FGDs each comprising of 8-10 adults were conducted; older women (40–60 years), older men (40-60 years), younger women (18-39 years), and younger men (18-39 years). During the FGDs, participants visually inspected seven samples of LLINs that were “too-torn” based on the proportionate hole Index (PHI) recommended by the World Health Organization guidelines on LLIN testing, the nets were brought to the discussion, and participants had to determine if such LLINs were to be kept or discarded. The study assessed responses from the same participants that attended FGD and also responded to the structured questionnaire, 117 participants fulfilled the criteria, thus data from only 117 participants are analyzed in this study. In FGDs, the Physical condition of LLIN influenced the decision to discard or keep a net. Those of older age, women and householders with lower income were more likely to classify a WHO “too-torn” net as “good”. The common methods used to discard LLINs were burning and burying. The findings were seen in the quantitative analysis. For every additional hole, the odds of discarding a WHO “too-torn” LLIN increased [OR=1.05 (95%CI (1.04 – 1.07)), p<0.001]. Younger age group [OR=4.97 (95%CI (3.25 – 7.32)), p<0.001], male-headed households [OR=6.85 (95%CI (4.44 –10.59)), p<0.001], and wealthy households [OR=3.88 (95%CI (2.33 – 6.46)), p<0.001] were more likely to discard LLINs: Physical condition of LLINs was the main determinant for discarding or keeping LLINs and the decision to discard the net is associated with the socioeconomic status of the household, and the age and gender of respondents. WHO “too torn” nets are encouraged to be used instead of none until replaced, and disposal of nets should be based on recommendation.
Effects of sample preservation methods and storage duration on the performance of mid-infrared spectroscopy for predicting the age of malaria vectors
Authors:   , Mgaya Jacqueline
Published: November 2023

The study assessed the effects of different preservation methods and storage durations on the performance of mid-infrared spectroscopy for age-grading malaria transmitting mosquitoes. Laboratory-reared Anopheles arabiensis (N=3,681) were collected as 5 or 17-day olds and killed with ethanol then preserved using either silica desiccant at 5°C, freezing at -20°C, or absolute ethanol at room temperatures. For each preservation method, the mosquitoes were divided into three groups and stored for 1, 4 or 8 weeks, then scanned using the mid-infrared spectrometer. Supervised machine learning classifiers were trained with the infrared spectra, and used to predict the mosquito ages. The classification of mosquito ages (as 5 or 17-day old’s) was most accurate when the samples used to train the models and samples being tested were preserved the same way or stored for equal durations. However, when the test and training samples were handled differently, the classification accuracies declined significantly. Support vector machine classifiers (SVM) trained using spectra of silica-preserved mosquitoes achieved 95% accuracy when predicting the ages of other silica-preserved mosquitoes, but this declined to 72% and 66% when age-classifying mosquitoes preserved using ethanol and freezing. Similarly, models trained on one-week stored samples had declining accuracies of 97%, 83% and 72% when predicting ages of mosquitoes stored for 1, 4 or 8 weeks respectively. When using mid-infrared spectroscopy and supervised machine learning to age-grade mosquitoes, the highest accuracies are achieved when the training and test samples are preserved the same way and stored for the same durations. Protocols for infrared-based entomological studies should emphasize standardization of sample-handling procedures.
Effects of boundary condition on seismic performance of container crane
Authors: Nguyen Van Bac , Nguyen Anh Dan
Published: November 2023

Container crane structure plays a crucial role in loading and unloading goods from a container ship to harbors. In any case, a breakdown of the container crane would harm the economy of a country. The modern crane is bigger to satisfy the demand of the owner; therefore, it is less stable under seismic excitation. Engineers often encounter an issue for choosing the boundary condition of the simulated model of the container crane as the legs can be uplifted or derailed under strong earthquakes. In this case, the simple work of pinned boundary condition can be replaced by the elastic-no-tension element between the structure and the ground. In this way, the leg base is free to move in vertical direction, and its vertical reaction reduces to zero. The objective of this paper is to evaluate the seismic performance of a container crane by the time history acceleration analysis using two different base supports, i.e., pin and elasticno-tension supports. Firstly, horizontal response spectra of actual earthquakes are adjusted by scaling the amplitude of each ground motion to coincides with a specific target spectral acceleration at the fundamental period of the container crane and then determined the scale factor. Afterwards, the ground motions are generated based on the scale factor, and they are used as input data for dynamic analysis by time history method. Two cases of target spectral accelerations will be determined to evaluate the dynamic responses of structure for uplift and no uplift phenomenon. Some response characteristics, i.e., total base shear and portal drift, are investigated. From that, the results show that the elastic-no-tensions supports are suitable for simulating the real behavior of the container crane when it is analyzed under high seismic excitation.

Super high-rise buildings are being built more and more in the world and in Vietnam. Currently, foreign experts are presiding over most of the geodetic work during the construction of super high-rise buildings in Vietnam. Vietnamese technicians are only allowed to participate in the implementation at the request of these experts. Therefore, in Vietnam, it is necessary to have a full research on geodetic work in the process of building super high-rise buildings. This article presents the research results of a group of lecturers in the Geodetic Department, Hanoi University of Civil Engineering on the ability to combine terrestrial and satellite measurements, which are measured by total station and GNSS, in geodetic work when building super high-rise. The research results are the process of building and data processing one-level spatial networks, determining three-dimensional coordinates in a unified coordinate system, step by step ensuring accuracy throughout the construction process, exploiting super high-rise buildings.

The flatness of the surface is one of the important indicators to access the quality of the concrete surface during and after the construction process. The terrestrial laser scanner with many outstanding advantages in accuracy, high point density and high data rate acquisition has become an effective tool for construction quality inspection. The most advantage of the ground laser scanner for assessment of floor flatness compared to traditional methods is so quickly data acquisition and able to measure when the concrete floor is still wet. This allows the contractor to identify and fix the errors without waiting for the floor to dry so it can reduce both costs and time for construction. However, in Vietnam today, there is still a lack of standards as well as technical guide to apply this technology in evaluating the flatness of the surface construction effectively. The article proposes a four-step procedure to access the flatness using a laser scanner based on the ASTM E1155 standard. The field work is carried out by using GLS 2200 scanner and uses the four-step procedure to evaluate the surface flatness of the construction. From experimental results, it can be confirmed that the above four-step proposed procedure is suitable to evaluate the flatness of the surface construction by laser scanner in Vietnam conditions. The article is an initial study from theoretical analysis, development of procedure and field work. Therefore, the article can be used as a technical guide for geodetic engineers in the quality control constructionas well as a reference for state management agencies in making standard for the assessment of surface flatness using terrestrial laser scanner.

This research discusses the impact of migration on social change in Ambon City, Indonesia. Ambon City, as the economic and cultural center of the Maluku region, has undergone significant transformation due to migration, both internal and external. This research uses a descriptive qualitative approach through literature study. The results of this study outline how migration has created challenges in terms of social integration, changes in cultural identity, and the potential for social conflict. On the other hand, migration also brings opportunities in the form of economic growth, cultural diversity, and cross-cultural innovation. To overcome these challenges, the Ambon City government needs to formulate policies that support social inclusion, sustainable economic development, and preservation of cultural identity. Collaboration between natives and migrants should also be enhanced to create a harmonious and competitive environment, ensuring that Ambon City remains an attractive and diverse place for all its residents. This research underscores the importance of an in-depth understanding of migration dynamics and social change to capitalize on migration opportunities while maintaining the social, economic and cultural sustainability of Ambon City.
Aborto después de nacer: un análisis bioético de la vida humana en sus primeras etapas
Authors: Casillas Castañeda Ana Jimena
Published: November 2023

"Ante el aborto existen muchos puntos de vista opuestos que causan problemas en la sociedad en lo que se refiere a su regulación para la protección de la vida. Dadas estas contradicciones busco exponer los puntos en los que se utilizan conceptos básicos de Metafísica para defender la vida del no nacido. Mi punto de partida es un artículo filosófico que ha causado mucha controversia en el presente tema. Los filósofos Giubilini y Minerva en su artículo “Aborto después de nacer: ¿por qué el bebé debe vivir?” publicado en el Journal of Medical Ethics hablan acerca del aborto como “la aniquilación de una pura potencia”. Eso ha hecho que el aborto se haya ido aceptando gradualmente en la sociedad, ya que ésta no considera que tal acción va en contra de la calidad de vida del feto, al eliminarlo. Los autores demuestran, argumentativamente, que los fetos y recién nacidos no tienen el mismo estatus ontológico y moral que una persona. Para ellos, ambos (feto y recién nacido) son potencialmente personas y son moralmente irrelevantes; y que la adopción tampoco se encuentra en el mejor interés de las personas. De este modo pretenden justificar el quitar la vida a un recién nacido ya que, según ellos, “no es una persona en acto ”."

CLIMATE CHANGE AWARENESS OF THE BARANGAY OFFICIALS IN THE MUNICIPALITY OF SAINT BERNARD, SOUTHERN LEYTE
Authors: Gary D. Garcia
Published: November 2023

Eastern Visayas has been experiencing a series of calamities since the tragic mudslide in barangay Guinsaugon, Saint Bernard, Southern Leyte in 2006. As a result, a state of calamity was declared in almost every part the country due to heavy rains that devastated agriculture, livestock and properties. This study was conducted to assess the level of the barangay officials’ related awareness on climate change, more particularly on its cause and effect, thought and belief, and the course of action through barangay ordinances related to climate change. The study utilized the descriptive survey method of research. Data were analyzed and interpreted using weighted mean and percentages to describe the level of awareness of the elected officials towards climate change. Majority agreed that climate change is happening and presently affecting the people in the barangays. The thought of respondents towards climate change is highly coupled with religious thinking. The actual state of affairs (situation) is the priority of the barangay officials leading to the inaccurate expectation of the long term effect of climate change. Barangay officials’ awareness on the causes and effect of climate change is observable but limited on vulnerability and adaptation. Thus, additional exposure and in-depth understanding on climate change is recommended.

Wood apple (Limonia acidissima L.) is a very nutritious fruit grown in Southeast Asia for its natural source of antioxidants and medicinal properties, which are attributable to large bioactive compounds such as phenols, alkaloids, carotenoids, flavonoids, coumarins, carbohydrates, minerals, vitamins and anti-carcinogenic compounds. However, the high moisture content of wood apple can result in rapid degeneration after cropping and drying is one of the most common methods for preservation of wood apple as well as extending its lifetime. This study aimed to investigate the effects of various drying temperatures (50ºC, 60ºC, 70ºC, and 80ºC) on the moisture profile, total phenolic content (TPC), antioxidant activity and sensory quality of wood apple pulp. TPC and antioxidant activity were tested via the Folin-Ciocalteu method and free radical scavenging ability of 1,1-diphenyl-2-picryl hydrazyl (DPPH), respectively. Optimal results were obtained at the drying temperature of 70ºC for 150 minutes which yielded the highest TPC (30.871±0.31 mgGAE/100g of dry matter (DM)), antioxidant activity (20.655±0.29%), and highest mean sensory score.

Published: November 2023

The study was conducted to determine, compare and evaluate the selected functional properties of flour from three different varieties of sweet potato, namely, NSIC SP-32, PSB SP-17 and VSP-6 produced by PhilRootcrops, Visayas State University. These properties are necessary for the development and improvement of food products from sweet potato which provide an excellent means of increasing the utilization of this nutritious high-yielding crop. All the flour samples showed great potential in the characteristics (moisture content and pH) for long shelf life. PSB SP-17 flour had the highest potential in the applications for thickening, binding and gelling in food processing compared to the other two flour samples, as supported by the data on water absorption capacity and gelation capacity. PSB SP-17 flour showed good fat-binding ability for applications in meat processing and colloidal food systems. It also showed the highest viscosity and lowest amylose content. NSIC SP-32 flour possessed these characteristics but only came second to PSB SP-17. VSP-6 showed the highest bulk density which is of good use in packaging and food preparations. It also showed the highest foaming capacity compared to NSIC SP-32 and PSB SP-17.
Drivers and Impacts of Microplastics in Estuaries
Authors: Sylvester T. Cortes  , Julie B. Otadoy
Published: November 2023

The goal of this paper is to create a conceptual model reflecting the pathway of microplastics (MPs) before they reach estuaries by synthesizing results from previous studies that identify major potential drivers of MPs contamination in the aforecited marine receptor. Further, the paper reports on organisms which so far are documented to be affected by these microdebris in either pelagic or benthic zones of the estuarine ecosystem based on studies reviewed. Results indicate that domestic effluents, industrial wastes, fishing lines, and recreational activities are the primay sources of MPs accumulating in estuaries. The model also presents that MPs enter the marine receptor through the sewer system, direct dumping, extreme weather conditions, or via the river. There are 23 species of fish from 13 families that are documented with MP ingestion and mostly are bottom-feeders. This, in effect, allows the entry of MPs into thehuman food web. Hence, the present study recommends intensive information, education and communications campaign (IEC) such as IEC on banning of single-use packaging which intensify MP abundance not only in estuaries but in other bodies of water whether in inland or open sea.

Authors: Lara Jessa Oyong  , Andresito Acabal
Published: November 2023

This study aimed to determine the effects of the interaction in the production of lovastatin between carbon sources (lactose, honey and glucose as the control) in four different incubation periods (3, 6, 9 and 12 days) with 1% w/v and 2% w/v concentrations. Results showed that honey was the best carbon source in producing an average concentration of 827.11 ± 382.20 μg mL-1 lovastatin. One percent (w/v) of carbon source produced 1084.00 ± 188.70 μg mL-1 of lovastatin, which is higher than the one produced at 2% (w/v) (396.30 ± 102.44 μg mL-1). Highest yield (815.82 ± 469.07 μg mL-1 ) of lovastatin was obtained on the sixth day of incubation using honey as the carbon source.

Parashorea malaanonan, of the family Dipterocarpaceae, is one of the most economically and ecologically important timber species in the Philippines. Presently, genetic resource of this species is highly threatened and its long-term survival is critically endangered. Hence, genetic investigation for the species is very essential. In this study, 23 microsatellite DNA loci developed for Shorea leprosula and S. curtisii were cross-amplified to P. malaanonan. This results a high transferability rate of 74%. The findings provided additional evidence for the potential cross-amplification of Shorea SSRs across genera within Dipterocarpaceae. The five polymorphic microsatellites are useful for further genetic studies of the remaining P. malaanonan populations.
Application of Expired Alprazolam Drug as Corrosion Inhibitor for Aluminum in 3 M HCl Environment
Authors: Raghavendra Narasimha
Published: November 2023

The aim of the present research is to examine the application of expired alprazolam drug as a corrosion inhibitor for aluminum (Al) in 3 M hydrochloric acid (HCl) solution. The corrosion protection of expired alprazolam drug was screened by plotting the Tafel plot and conducting impedance spectroscopy, gasometric and quantum chemical studies. The protection efficiency of the alprazolam drug exceeds 90% at the concentration of 1.2 g/L of the drug at 60◦C. The electrochemical Tafel plot shows that the examined drug acts as mixed type. Impedance spectroscopy results show that increasing the amount of expired alprazolam drug enhances the value of charge transfer resistance around the electrode-solution interface. Gasometric studies show that the presence of expired alprazolam drug decreases the volume of hydrogen (H2) gas evolution. Also, quantum chemical calculations were done to calculate the inhibition mechanism. Thus, the expired alprazolam drug can be used as an inexpensive and nontoxic corrosion inhibitor for the studied system.

Authors: Vernabelle L. Balmori  , Julie D. Tan
Published: November 2023

Starch-degrading microorganisms from decaying rootcrop tubers were isolated and screened as potential starter cultures in the production of natural sweetener from taro (Colocasia esculenta). A total of 43 microbial isolates were collected from the samples, 24 of which showed starch-degrading potential as exhibited by positive results for iodine test on starch-agar plates. Further test using DNS method showed that molds in general have greater starch-degrading abilities than bacteria and yeasts. The top two isolates with the highest hydrolyzing activity were molds isolated from decaying taro and cassava tubers. The fermentation of cooked taro (VG-9) substrate using the two most promising isolates yielded syrups with TSS values of 11.65 and 13◦ Brix and pH of 5.4 and 4.06. Qualitative tests for sugars showed that the syrups contain reducing sugars, particularly monosaccharides and ketoses most of which are generally referred to as good or prebiotic sugars. Results of the study imply that taro is a potential raw material for natural sweetener production. It is recommended to study combinations of microorganisms to carry out the optimum fermentation process and produce a good quality sugar alternative with maximum health benefits.
