Published: September 2023

Drought is considered the major threat and most damaging abiotic stress for rice production.However, some traditional upland rice varieties (TURVs) may have some forms of tolerance to various stresses compared to new elite varieties. Two experiments were conducted. Experiment to determine the morpho-physiological response, phenotypic diversity, and similarity of 13 TURVs and 2 check varieties to mild drought stress at the seedling stage (Experiment 1 (E1) and to determine the molecular diversity and genetic similarity of the genotypes using selected simple sequence repeat (SSR) markers ((Experiment 2 (E2). In E1, all TURVs were highly tolerant under mild drought stress for a physiological response. Standardized Shannon-Weaver Diversity Index(H’) showed zero to low phenotypic diversity for qualitative traits. However, the phenotypic diversity of quantitative traits ranged from moderate to high for well-watered conditions, low to high for drought conditions, and moderate to high for re-watered conditions. Cluster analysis through Ward’s minimum variance based on pooled phenotypic data grouped the genotypes into three major clusters at 7 Euclidean distances. For E2, polymorphic information content values from 24 polymorphic SSR markers ranged from slightly informative (RM256) to highly informative (RM206), with a mean of 0.61. Nei’s gene diversity mean was 0.62 and values varied from 0.26 (RM256) to 0.86 (RM206). Based on Jaccard’s similarity coefficient, rice genotypes were grouped into nine minor clusters. The results indicate that TURVs harbor moderate to high allelic diversity and there are potential tolerance genes for mild drought stress that can be utilized in breeding programs for drought-tolerant rice varieties.

Authors: Fitrianti Vita , Ghafari Muhammad Irsyad Abiyusfi
Published: September 2023

Microplastics have recently received high global attention, as their widespread presence can potentially cause physical and toxicological risks to organisms. The west coast of Lombok Island in Indonesia has a high potential for microplastic accumulation; even so, its presence in this area was not well studied. Therefore, this study aimed to describe the distribution and density of microplastics within the sediments on the west coast of Lombok. Microplastic sampling had been carried out in the northern, middle, and southern portions of the west coast of Lombok based on distinct geographical and vegetational characteristics. Sediment samples were taken within the HTL (High Tide Line) zone based on the excavation depths categories, i.e. A (0–2cm), B (2–4 cm), C (4–6 cm), D (6–8 cm), and D (8–10 cm). The sediment samples were filtered using an aluminum sieve with a mesh size of 4.75 mm, targeting microplastic pieces below that size. A total of 16,685 microplastic debris were found distributed horizontally and vertically throughout the station. There was a significant difference in the microplastic density distributed between stations [F(10,22) = 6.96, p < 0.001] and between sediment depths [F(10,44) = 9.07,p < 0.001]. The order of average microplastic concentration was southern > northern > middle stations group. The highest microplastic number recorded in SMP11 (southern station, open bay, high anthropogenic activity, with river and primary mangrove vegetation) was as many as 2,361 (density, D = 125,920.00 ± 204.33 items/m3), whereas SMP01 (northern station, open bay, low anthropogenic activity, and with river and secondary mangrove vegetation) had the lowest microplastic number of 678 (D = 36,160.00 ± 72.82 items/m3). In general, the majority of microplastics (45.76%) were distributed on the sediment surface (A–B), where there was a repeating pattern in the difference of microplastic density fluctuations of about 3% at every 4cm of sediment depth (B–C and D–E), which is thought to be driven by daily tidal fluctuation.There was no clear pattern that indicated whether the specific type of shoreline or the presence of rivers and mangroves had an influence on the level of microplastic accumulation. However,the southern stations group had a considerably higher average of microplastic accumulation.We suspect that the geographical position towards the main ocean current contributes greatly to the microplastic accumulation at the site.

Published: September 2023

Snacking can be defined as eating outside the three main meals in a day, regardless of the amount or type of foods consumed. Snacking patterns vary between developing and developed countries, and across nations around the globe. Utilizing data from the Philippine ENNS collected in 2018 and 2019, the authors were able to determine the distribution and frequency of snacking among Filipino children, the type of snack foods consumed, and the contribution of snack foods to their energy and dietary intakes. Results revealed that around 70% of Filipino children consume snacks once a day, usually as afternoon snacks.Moreover, consumption of snack foods decreases as the age of children increases. The snack foods frequently consumed are pastries and cookies, bread, crackers, and biscuits, along with sugar-sweetened beverages – with an average energy intake of 300.0 kcal from snack foods. Snack foods contributed 31.2% of the total daily energy intake for Filipino children aged 3–5 yr old, 25.1% in 6–9 yr old, and 21.6% in 10–12 yr old. The nutrient content of the snack foods ranged from 29.5–46.7 g protein, 295.4–347.8 mcg RE vitamin A, 5.4–7.7 mg iron, and 272.3–381.7 mg calcium. More than half of Filipino children consumed snack foods at least once a day, with a higher proportion of snackers meeting the recommended energy intakes and estimated average requirements than non-snackers. However, the promotion of healthy snack choices such as fruits and vegetables and other nutrient-dense foods needs to be strengthened. Findings support the need to develop guidance on healthy snacking among Filipino children and represent a key target for food and nutrition policies to improve the dietary quality of snacks in this population.
Gluing Characteristics of Giant Bamboo Using Four Commercial Adhesives
Authors: Jimenez Juanito , Ramos James Edelbert
Published: September 2023

The study aimed to determine the bonding performance of laminated giant bamboo[Dendrocalamus asper (Schult.) Backer] glued with four commercial adhesives (PVAc-D3, PUR, UF, PF) at different surface pairings (pith-pith, pith-skin, and skin-skin) and glue spread rates(100, 150, and 200 g/m2). Kiln-dried giant bamboo poles were ripsawn, planed, and cut to length to produce slats for lamination. Slats for surface roughness and wettability tests were sanded with 180-grit sandpaper on both skin and pith surfaces. Surface roughness of the skin and pith was measured using Mitutoyo SJ–210 Surftest unit, whereas wettability was determined via the sessile drop method. Giant bamboo slats were bonded using specific lamination parameters for each adhesive. Tensile shear tests at dry and wet conditions were performed on the laminates to determine bond strength. The results showed that the bamboo pith had a rougher texture than the skin but with insignificant contact angle differences. Moreover, PVAc-D3 and PUR gave the highest and lowest initial contact angles on both sides, respectively, with PUR maintaining the smallest values throughout the contact duration. Adhesive, surface pairing, and some interactions (adhesive x glue spread and adhesive x surface pairing) significantly affected the dry shear strength, whereas adhesive and adhesive x surface pairing influenced wet shear strength. PUR-bonded laminates had the highest dry shear strength, followed by PF, PVAc-D3, and UF. In terms of wet shear strength, only PVAc-D3 did not conform to the minimum glue bond strength requirement of more than 1 MPa and cohesive bamboo failure of at least 40% (PNS 2099:2015). Skin-skin and pith-pith surface pairing yielded the highest and lowest dry shear strengths, respectively. Increasing the amount of glue did not translate to a stronger bond. PUR, UF, and PF are feasible alternatives to PVAc-D3 in engineered bamboo production for various end-uses.

Published: September 2023

Pesticides pose a serious risk to the environment and public health when used in crop production in an unsafe and indiscriminate manner. Moreover, there is a preconceived notion that conventionally grown crops are not as safe as organic crops due to the presence of pesticide residues. To address this, an intervention that focused on farmers’ training on proper pesticide management was conducted. Two farmer clusters were organized separately, and pesticide usage and practices were monitored and evaluated. The results of the evaluation indicated a significant decline in the usage of pesticides not registered for cabbage and eggplant production. Residue analysis for major insecticide groups (organochlorines, organophosphates, and pyrethroids) of the harvested crops showed that 100% of the eggplant samples (n = 20) and 80% of the cabbage samples (n = 20) had non-detectable pesticide residues (< 0.01 mg/kg). The cabbage samples with detectable residues are found to be compliant with the currently established CODEX and ASEAN maximum residue limits for the indicated pesticides. Overall, this suggests that training and monitoring activities conducted to strengthen the knowledge and adherence to pesticide safety practices resulted in safe conventional vegetable production. It is recommended that farmers’ training and other extension activities be conducted periodically to promote the judicious use of pesticides for food safety.

The six species of the genus Bubalus include the lowland and mountain anoa, Asian wild buffalo, tamaraw, swamp buffalo, and riverine buffalo. Few studies were conducted on the matrilineal phylogeny and genetic diversity of Bubalus species. In addition, there is controversy regarding the identity of the two domesticated water buffaloes in the Philippines – the introduced riverine and the native swamp buffalo. Thus, this study aimed to determine the genetic distance and phylogenetic relationship of Bubalus species using the mitochondrial cytochrome b (cytb) variation and to re-evaluate the taxonomic species designation of Bubalus bubalis. A total of499 Philippine cytb sequences from this study (n = 179), as well as other Asian countries (n = 319)and Syncerus caffer (n = 1), from NCBI were included in the analysis. The highest interspecies genetic distance (d) (0.040) was between the tamaraw and lowland anoa, whereas the lowest genetic distance (0.020) was between mountain and lowland anoa. Moreover, the phylogenetic tree indicated 52 haplotypes that delineated three groups, including lowland anoa, mountain anoa, and tamaraw with two domesticated buffaloes. The latter group further separated into three species – tamaraw, riverine, and swamp buffaloes. The analyses of genetic distance,phylogeny, and median-joining network structure based on cytb confirmed that the swamp buffaloes from Occidental Mindoro and South Cotabato, Philippines belong to maternal lineage B. Karyotype analysis consistently confirms that riverine buffaloes possess 50 chromosomes, whereas swamp buffaloes have 48 chromosomes, aligning with previous findings. Moreover, the swamp and riverine buffaloes appear to be distinct species, with the swamp buffalo having a closer affinity to the tamaraw than to the riverine buffalo. We, therefore, propose to revive the species assignment of the Bubalus kerabau Fitzinger, 1860 as a distinct species to the swamp buffalo. Furthermore, a common maternal ancestry was confirmed between the tamaraw and two domesticated buffaloes – the swamp and riverine. Research findings provided valuable information on understanding and monitoring the matrilineal genetic diversity of the genus Bubalus toward conservation and management.

Published: September 2023

Based on the ultimate and proximate analysis, brown coal and ceara rubber (biomass) had low calorific values of 5,349 and 3,319 kcal/kg, respectively. The ceara rubber was not included in the food ingredient because it contained chemicals such as toxic cyanide acid. This research was conducted to utilize the biomass in biobriquettes that had added value and became a more environmentally friendly energy source compared to fossil fuels. The mixing ratio of the biobriquette was determined at various particle sizes. Biobriquette preparation included crushing, drying, size reduction, sieving, mixing, molding, and testing. The produced biobriquette was cylindrical with a diameter of 3 cm and pressing pressure of 7 metric tons. Biobriquette analysis included compressive strength tests, tests of density, tests of moisture, ash, and fixed carbon content, tests of the volatile matter, and tests of calorific values. These biobriquettes were expected to increase the selling value of low-rank coal and become one alternative to more environmentally friendly solid fuel for cooking purposes. Based on the research results, the best biobriquette had a particle size of 60 mesh. The result showed that the best particle size was on the mixing ratio of 3:2, with the net calorific value reaching 4,300.8 kcal/kg.

Published: September 2023

Arcangelisia flava, also known as yellow root, is a woody vine indigenous to the Philippines. It has been established that it possesses medicinal properties, and several of its bioactive compounds have been identified. However, most of its possible bioactive nonpolar chemical compounds remain unidentified. In this study, the stem of A. flava was investigated for its chemical components, FTIR fingerprinting, and antioxidant activity. The stem of A. flava was chopped, ground, and then extracted with hexane per gram of A. flava. Thin-layer chromatography (TLC), phytochemical screening, GC-MS and FTIR analyses, cupric-reducing antioxidant capacity (CUPRAC), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays were performed to evaluate the chemical components of A. flava hexane extract. TLC and phytochemical screening revealed the presence of some organic acids, triterpenes, sterols, essential oils, phenols, and flavonoids. Further characterization using GC-MS analysis revealed 64 chemical components classified into hydrocarbon, ketone, alcohol, aromatic compounds, aldehyde, ester, organosilicon, and other chemicals. The most abundant compound was hexacosane with a relative abundance of 43.17%. This was followed by tetracosane (8.85%), o-xylene (8.09%), and hexatriacontane (5.72%). The FTIR spectrum also revealed the presence of hydrocarbons such as alkanes and alkenes, confirming the 60% abundance of such class of compounds as revealed by GC-MS. Meanwhile, based on the CUPRAC and DPPH assay conducted, the hexane extract from the stem of A. flava had low antioxidant capacity. Based on the literature search, this is the first time the chemical composition of A. flava hexane extract has been evaluated and its chemical compounds identified. The findings presented in this paper should be taken into account for any future research on the species’ therapeutic properties.

Authors: Ahmad Waqas , Naeem Muhammad
Published: September 2023

Analyzing digestive enzyme concentration in the gut is important to know about the digestive physiology of fish. Therefore, we determined concentrations of protease, lipase, and amylase enzyme in gut extracts of juvenile and adult groups of Notopterus notopterus relative to total body length (TBL), body weight (W), gut length (GL), relative gut length (RGL), Zihler's index (ZI) and condition factor (K). A total of 60 N. notopterus specimens (30 juvenile and 30 adult) were collected, the gut of each removed, homogenized, and evaluated for the concentrations of protease, lipase, and amylase. Protease and lipase concentration were observed significantly (P < 0.01) correlated with increased TBL, W, and GL in both juvenile and adult groups of N. notopterus. Amylase concentration significantly (P < 0.01) increases with an increase in TBL, weight, and GL in the juvenile group, whereas amylase concentration significantly (P < 0.01) decreases with an increase in TBL, W, and GL in the adult group. K had a significant (P < 0.01) positive correlation with protease and lipase concentrations in both juvenile and adult groups, whereas K showed a significant (P < 0.01) positive correlation with amylase concentrations in juvenile and significant (P < 0.01) negative correlation in the adult group. Protease and lipase concentration were observed significantly (P < 0.01) correlated with an increase in ZI in the juvenile and adult groups. Amylase concentration significantly (P < 0.01) increases with an increase in ZI in the juvenile group, whereas amylase concentration significantly (P < 0.01) decreases with an increase in ZI in the adult group. The concentrations of protease (344.12 U/mg) and lipase (172.49 U/mg) were observed high in juvenile and adult groups, whereas amylase concentration (3.80 U/mg) was found low in the juvenile and adult N. notopterus groups. Present study results revealed the digestive physiology and carnivorous behavior of N. notopterus. Moreover, information from the present study about digestive enzyme concentration in juvenile and adult species of N. notopterus provides valuable information to understand the digestive physiology of carnivorous fishes.

Published: September 2023

Background: Many developmental theories have mentioned the motivation to move as a motor driver and used it to explain how children acquire new movement patterns. Objectives: Therefore, the aim of this study was to investigate the relationship between motivation to move and the development of fundamental movement skills (FMS) among urban and rural preschool children in Iran. Methods: The statistical population of this cross-sectional study included a sample of 4-6-year-old preschool children and their caregivers from Khorramabad urban and rural areas in Iran. A sample of 400 (202 from urban areas and 198 from rural areas) were selected using stratified random sampling. Data collection tools included the Children Movement Motivation Questionnaire (CMMQ) and Test of Gross Motor Development–Third Edition (TGMD-3). The Pearson correlation coefficient and independent t-tests at a significance level of P < 0.05 were used to analyze the research data. Results: In both groups of children resident in urban and rural areas, a positive and significant relationship was observed between the CMMQ and TGMD-3. A significant difference was found between urban and rural children on scores of the CMMQ and TGMD-3, with rural children scoring higher on both. Conclusions: This work provides support for the link between motivation and motor development in children. Moreover, the child's environment also has an impact on both motivation and development. Both motivation and the child's environment should be considered when developing programs that support typical development or rehabilitation plans for children who are not developing typically.

Trust Architectures in Research
Authors: Rasmussen Lisa M. ,   Saint Louis University
Published: September 2023

The research enterprise depends on trust, especially trust in data reliability and ethical conduct of research. This trust is accomplished via systems, or “architectures,” that do the work of ensuring trustworthiness in research when individuals are not able to assess it for themselves. In the United States and many other countries, national laws or regulations constitute the research ethics trust architecture. But new research methods, such as citizen science, DIY biology, biohacking, or corporate research, avoid such regulations because they draw on new means of funding, disseminating, and conducting research. This challenges the sufficiency of the traditional approach and requires us to revisit how we generate trust in the research enterprise. In this article, I discuss how new research challenges the existing trust architecture, offer some necessary elements of trust architecture in general, and use citizen science as a case study to illustrate how new, ethically meaningful trust architectures could be built.

Published: September 2023

Orthogonal Frequency Division Multiplexing (OFDM) is well recognized as a very efficient multicarrier technology. OFDM has witnessed a significant increase in its utilization within contemporary wideband digital communication systems. The technology possesses several notable benefits, including its capacity to effectively manage challenging channel circumstances, optimize spectrum utilization, mitigate inter symbol interference (ISI), and support high data transmission rates. Hence, it has been employed in several forthcoming wired and wireless communication systems, such as 4G LTE mobile communications. This work primarily concentrates on the performance assessment and investigation of the OFDM system in the presence of Rayleigh fading channels. By analyzing the outcomes of simulations, we may gain insights into various impacts and signal-to-noise ratios (SNRs). In order to determine their respective signal delivery capabilities, channels are compared and ranked. The evaluation of system performance involves assessing the quality of received signals, including factors like as signal quality, bit-error rates (BERs), and peak signal-to-noise ratios (PSNRs).

Published: September 2023

Smartphones are a form of technology that is growing rapidly. The use of Smartphones has various impacts on users, especially school-age children. One of the impacts that can occur from using Smartphones on school-age children is the inhibition of psychosocial development. This research was conducted to determine the relationship between the level of Smartphone addiction and the psychosocial development of school-age children in agricultural areas. The method used in this study is by using a cross-sectional approach. Sampling using a simple random sampling technique obtained a sample of 150 respondents. Data collection used the SAS-SV questionnaire and the psychosocial development questionnaire. This study used a relationship test, namely the Kendal-Tau test c. The study results showed that students with Smartphone addiction were in the 106 (70.7%) addiction category and 44 (29.3%) non-addictive categories. While the psychosocial development of children in the abnormal category was 86 (57.3%), the borderline category was 28 (18.7%), and the normal category was 36 (24%). These results show that the p-value obtained is 0.000 or a p-value <0.05. It can be said that there is a relationship between the level of Smartphone addiction and psychosocial development. In addition, the value of strength in both relationships is 0.340. This value is included in the weak category. So, the relationship between the two variables is included in the weak category. Then the level of correlation shows positive results, namely the higher the level of smartphone addiction, the worse the psychosocial development of children.

Context.—

The Sustainable Predictive Oncology Therapeutics and Diagnostics quality assurance pilot study (SPOT/Dx pilot) on molecular oncology next-generation sequencing (NGS) reportedly demonstrated performance limitations of NGS laboratory-developed tests, including discrepancies with a US Food and Drug Administration–approved companion diagnostic. The SPOT/Dx pilot methods differ from those used in proficiency testing (PT) programs.

Objective.—

To reanalyze SPOT/Dx pilot data using PT program methods and compare to PT program data.

Also see p. 136.

Design.—

The College of American Pathologists (CAP) Molecular Oncology Committee reanalyzed SPOT/Dx pilot data applying PT program methods, adjusting for confounding conditions, and compared them to CAP NGS PT program performance (2019–2022).

Results.—

Overall detection rates of KRAS and NRAS single-nucleotide variants (SNVs) and multinucleotide variants (MNVs) by SPOT/Dx pilot laboratories were 96.8% (716 of 740) and 81.1% (129 of 159), respectively. In CAP PT programs, the overall detection rates for the same SNVs and MNVs were 97.2% (2671 of 2748) and 91.8% (1853 of 2019), respectively. In 2022, the overall detection rate for 5 KRAS and NRAS MNVs in CAP PT programs was 97.3% (1161 of 1193).

Conclusions.—

CAP PT program data demonstrate that laboratories consistently have high detection rates for KRAS and NRAS variants. The SPOT/Dx pilot has multiple design and analytic differences with established PT programs. Reanalyzed pilot data that adjust for confounding conditions demonstrate that laboratories proficiently detect SNVs and less successfully detect rare to never-observed MNVs. The SPOT/Dx pilot results are not generalizable to all molecular oncology testing and should not be used to market products or change policy affecting all molecular oncology testing.

Published: September 2023

This study aims to improve the thermal and mechanical properties of epoxy-based materials. For this purpose, the structure of epoxy resins was changed by chemical modification and epoxy resin containing urethane was synthesized. The synthesized resin was blended with commercial epoxy resin at the ratios of 25%, 50%, 75% by weight and hardened by curing. The thermal and mechanical properties of urethane-containing epoxy materials prepared in different proportions were compared with those produced from commercial epoxy resin. The structural characterization of the prepared materials was investigated by Fourier Transform Infrared Spectroscopy (FTIR) analysis, their thermal behavior was investigated by Thermogravimetric Analysis (TGA), and their mechanical properties were investigated by Dynamic Mechanical Analysis (DMA). TGA and DMA analyses of the materials showed that the presence of urethane in the structure of epoxy resins significantly changed the mechanical and thermal properties. It was observed that the storage and loss modulus values of urethane-containing resins increased approximately 2.5 times compared to commercial epoxy resins, and a decrease of approximately 10% in thermal degradation temperatures was observed.

The chromium coating of plastic/polymer materials through electrolysis method has attracted attention for improving material properties. The most common material used to be coated is the Acrylonitrile Butadiene Styrene (ABS), but has disadvantages compared to polyamides (PA), such as low thermal resistance. PA’s high water retention disadvantage can be substituted by using fillers such as clay, etc; so in this study, 40% Wollastonite filled PA has been used for chromium plating to increase the thermal resistance of the PA. The plates used were produced by injection molding method. The research is focused on the effect of time and concentration on coating performance in etching, activation (by palladium) and accelerator processes. SEM and EDX were used to characterize samples for surface morphologies and the microstructures of etching, activation and accelerator in the PA sub-plates. Additionally, cross-cut adhesion test has been applied to analyze the adhesion power of the interfaces. It was found that the thermal resistance of the metal plate on the polymer surface decreased as the time increased, in relation with the increasing wearing time of the metal plate mentioned above. The thermal resistance decreased as the polymer deformed in relation with the increase in etching solution’s concentration. It is also seen that the thermal resistance improved as the activation time increased. The adhesion and the thermal resistance did not improve as the time in accelerator process increased. Furthermore, the cross – cut adhesion tests on the same samples concluded that the results are in agreement with the other thermal resistance results.

Published: September 2023

The acceleration of industrialisation and population growth throughout the world have caused the rapid depletion of water resources in the last century. Industrial wastes are one of the major factors causing water pollution. One of the most effective and well-known methods to prevent water pollution is adsorption process. In this study, highly porous activated carbons were produced using waste fabric samples and their adsorption performances were determined in the presence an adsorbate to prevent water pollution. Methylene blue (MB) as the adsorbate was used for the adsorption tests. The waste fabric samples were carbonised at 400 °C, 500 °C and 600 °C to determine the effect of pre-carbonisation temperature on the adsorption performance. The activated carbon surface properties varied depending on the pre-carbonisation temperature. The surface areas of the samples were 1385 m2/g, 1583 m2/g and 1276 m2/g, and the total pore volumes were 0.7688 cm3/g, 0.9545 cm3/g and 0.7394 cm3/g, respectively. The results showed that the pre-carbonisation temperature affected the adsorption performance. The adsorption capacities of the activated carbons calculated according to the Langmuir adsorption model were 531.46 mg/g, 630.26 mg/g and 655.40 mg/g, respectively.
