A clear understanding of genetic diversity in weedy rice is important in improving protocols for its conservation, ex situ. To this end, Asian collections of weedy rice together with accessions of the wild AA genome species Oryza nivara Sharma et Shastry and Oryza rufipogon Griffith, and the cultivated species, Oryza sativa L. were characterized using...

Truncating a densely connected convolutional neural network with partial layer freezing and feature fusion for diagnosing COVID-19 from chest X-rays
Deep learning and computer vision revolutionized a new method to automate medical image diagnosis. However, to achieve reliable and state-of-the-art performance, vision-based models require high computing costs and robust datasets. Moreover, even with the conventional training methods, large vision-based models still involve lengthy epochs and costly disk consumptions that can entail difficulty during deployment due...
Differences in the parasitic effects of a bopyrid isopod and rhizocephalan barnacle on the portunid crab, Charybdis bimaculata
Bopyrid isopods and rhizocephalan barnacles are obligate parasite crustaceans which harm their decapod hosts. However, to the best of our knowledge, studies have not compared which of these parasites has a greater parasitic effect on its hosts. Here, the parasitic effect of the bopyrid isopod, Allokepon hendersoni, and an unidentified sacculinid rhizocephalan species, infesting the...
Influence of light, water motion, and stocking density on the growth and pigment content of Halymenia durvillei (Rhodophyceae) under laboratory conditions
The tropical red seaweed Halymenia durvillei Bory de Saint Vincent is a potential source of the high-value pigments, r-phycoerythrin (RPE) and r-phycocyanin (RPC). The unique properties of these pigments find many applications—from food to cosmetics, pharmaceuticals, and biomedical research. This study aimed to improve the land-based culture technology of H. durvillei by determining the appropriate...
A pivotal restructuring of modelling the control of COVID-19 during and after massive vaccination for the next few years
This paper presents a new mathematical feedback model to demonstrate how direct observations of the epidemiological compartments of population could be mapped to inputs, such that the social spread of the disease is asymptotically subdued. Details of the stabilization and robustness are included. This is a pivotal restructuring of modelling the control of corona virus...
Kinetics and Isotherm Studies on Adsorption of Hexavalent Chromium Using Activated Carbon from Water Hyacinth
The present study is focused on the use of activated carbon derived from water hyacinth (WH-AC) as adsorbent for the removal of Cr(VI) from aqueous solution. The optimized WH-AC was found to be mesoporous and considered as granular. The surface area of 11.564 m2/g was found to have a good adsorption capacity. The adsorption data...
Filipino Teachers’ Perspectives on the Effectiveness of Online Grammar Checkers and Plagiarism Detectors
Online grammar checker and plagiarism detectors are online tools or software which allows users to correct their works providing a reliable basis of right grammar and avoid plagiarism. This study used a descriptive research method to assess the perspectives of selected university instructors and professors handling research and writing courses on the effectiveness of online...
Team On Beams: Exploring The Demographic And Socio-Economic Profile Of Small Scale Industry Workers
Construction industry covers more than 70 percent of the total work strength of Philippines. This entails clear regulations and working conditions among its workers. In an attempt to discover the current condition of the workers, this study determined the demographic and socio-economic profile of construction workers in Malvar, Batangas, Philippines. Further, this also determined the...
Administrative Support and Job Satisfaction of Private School Teachers
The educational system today is anchored with serious challenges. The administration, together with the teachers, has a focal factor on the constant changes happening in the educational setting. To address the needs of the teachers to grow personally and professionally, administrative support is one of the vital factors that have given emphasizes. The purpose of...
On the Use of Surfactant-Complexed Chitosan for Toughening 3D Printed Polymethacrylate Composites
This work reports a simple approach to prepare toughened 3D-printed polymethacrylate (PMA) composites using surfactant-modified chitosan (SMCS) particles at loadings between 2–10 wt%. Chitosan (CS) is modified with anionic surfactant, sodium dodecyl sulfate, via ionic complexation to facilitate compatibility and dispersion of CS to PMA matrix by non-covalent interactions between the components. The study successfully...
