title: Results of Oceanographic Observations taken by CTD in North Pacific Areas under National Jurisdiction of the United States of America from the R/V Keifu Maru, Cruise No. KS25-01, from 2025-01-25 to 2025-01-26 (NCEI Accession 0311482)

description: KS25-01 cruise was conducted by the Japan Meteorological Agency's research vessel "Keifu Maru" from January to February, 2025. This dataset reports the results of marine observations conducted within the exclusive economic zone (EEZ) of the United States (Wake Atoll National Wildlife Refuge) during this voyage. The major objectives of the cruise are to monitor ocean conditions in the western North Pacific on a seasonal basis. During the cruise, vertical profiles of seawater temperature, salinity, dissolved oxygen, nutrients were observed. As a method of Hydrographic observation, vertical distributions of seawater temperature and salinity were measured using a CTD (Conductivity-Temperature-Depth profiler), and chemical analysis was performed on seawater samples collected by the CTD's multi-bottle sampler. This dataset is the U.S. State Department MSR RATS U2024-016. Data are in TXT and CSV formats.

title: Optimizing the plastic injection molding process and reducing warpage through response surface methodology

description: Warpage is a discomfort defect that stays on the plastic product during injection molding process (IMP). This paper demonstrates a method to reduce warpage during IMP by using a response surface methodology (RSM). Five key processing parameters are variables in the fitting function generated from RSM. Moldex3D software is the effective tool for designing IMP and analyzing defects such as warpage and shrinkage. The material is a general purpose polystyrene. The warpage prediction model, significant influencing factors, and optimization have been found. The results show that the prediction warpage is 0.834 mm corresponding to warpage reduction of 3.25% via using RSM method. The optimal value has recorded with 0.846 mm corresponding to warpage decrease of 1.86%. The technique is crucial for designing and setting the press parameters in actual IMP. The paper hopes that the results will encourage application of the method in real production to reduce fails and improve product quality.

title: Seventy-five years of insight – the impact of the Ukulinga very long-term grassland experiments

description: Two of the world’s oldest grassland experiments began in 1950/51 in Pietermaritzburg, South Africa. The Burning and Mowing Trial (BMT) tests how summer mowing and dormant-season burning or mowing regimes affect mesic grassland. The Veld Fertiliser Trial (VFT) examines how nitrogen, phosphorus fertilisers and lime influence grassland productivity, composition and diversity. Seventy-five years later, their impact was assessed through research output and value for education and networking. All published papers and their citations were identified, with key themes, leading authors and citation patterns of the top 10 papers from each trial analysed. A total of 26 and 24 peer-reviewed papers, cited 1 652 times, have been published from the BMT and VFT, respectively, with publication rates rising since 2000. Studies addressed treatment effects on soil, plants, invertebrates, microbes, regional comparisons and remote sensing. South Africans led authorship, with strong USA participation, and the top-10 papers reached a wide multinational audience. The Ukulinga LTEs demonstrated the vital role of regular burning or mowing, revealed how fertilisers can negatively impact grassland, and highlighted the importance of treatment interactions in shaping ecosystem dynamics. As key sites for research collaboration and education, they should be maintained long-term to advance understanding and address new questions.

title: Effect of induced astigmatism on vestibulo-ocular reflex

description: The vestibular-ocular reflex stabilises the retinal image and maintains balance during head movement. Astigmatism is one of the common refractive errors that can reduce the quality of visual inputs. The purpose of this study was to investigate the effect of induced astigmatism on the function of the vestibular-ocular reflex. This prospective semi-experimental study was conducted on 48 participants aged 20 to 40 years who had no history of neurological, vestibular, or eye disorders. Simple myopic astigmatism was induced using three positive cylindrical lens powers of + 0.50D, +1.50D, and + 2.50D at three axes of 180, 45, and 90 degrees in both eyes. The vestibular-ocular reflex was evaluated by the ocular Vestibular Evoked Myogenic Potential (oVEMP) through acoustic stimulation (a 500 hz tone burst at an intensity of 95 dBnHL) of the ear, with potentials recorded from the lower oblique muscle. The latency of the N1 and P1 waves and the amplitude of N1-P1 were recorded for all participants in the baseline condition (without any induced astigmatism) and under different induced astigmatism conditions. The latencies of N1 and P1 significantly increased with the increasing power of induced astigmatism; however, the powers of astigmatism had no effect on the amplitude of N1-P1. The axes of induced astigmatism did not have a significant effect on the latencies and amplitude of N1-P1. Induced astigmatism due to retinal image blur can deteriorate the function of the vestibular-ocular reflex by increase in the latencies of N1 and P1 oVEMP waves.

title: So far away: threshold copying distances for multiple-choice answers in different exam room settings

description: Paper-based multiple-choice exams are commonly used to assess students. Answer sheets for these exams have a configuration which affords a potential opportunity for cheating. A proportion of students report cheating on assessments. This research assessed maximum distances at which multiple-choice answer sheets could be copied in different rooms and for different viewing conditions. Participants were 10 healthy observers. Stimuli were generated on a University standard multiple-choice answer template with 40 answer responses recorded for each sheet. Responses were recorded at a range of test distances. Method of constant stimuli and probit analysis was used to estimate the threshold copying distance at which 62.5% of responses were correctly identified. With the copied sheets flat on a desk, testing took place in a tiered lecture theatre, a flat exam room, and with the exam positioned at different angles of regard: straight-ahead, at 45 degrees to straight ahead (oblique), and sideways. Threshold distances were greater in the tiered lecture theatre than the flat exam room and were greater in the straight-ahead position than the oblique position, in turn greater than the sideways viewing position. In the straight-ahead position in the tiered lecture theatre, exam answer sheets could be copied from 7.12 m; and in a flat room, from 3.34 m. For the sideways viewing condition threshold copying distances were 2.58 m (tiered lecture), and 2.36 m (flat room). Multiple-choice answer sheets can be copied from relatively large distances, a potential opportunity for academic dishonesty. Tiered lecture rooms should not be used as venues for multiple-choice exams. Multiple-choice answer sheets can be redesigned to reduce the risk of copying. These results will be of practical and theoretical interest to educators, administrators and students.

title: Colombian ocular diseases epidemiology study (CODES): glaucoma incidence and sociodemographic characterisation 2015–2020

description: Glaucoma encompasses a group of eye diseases that progressively damage the optic nerve, leading to vision loss and blindness. Understanding the incidence and demographic distribution is vital for public health planning and patient care. Previous small-scale studies in Colombia have reported the prevalence of glaucoma in individuals over 40 years between 1.1% and 5.29%. These data may not fully capture the true extent of the disease. Furthermore, with the ageing population, the incidence of glaucoma is likely to increase, highlighting the need for up-to-date incidence data to guide healthcare planning. Data were obtained from the Social Protection Information System, the primary health record repository of Colombia, using the International Classification of Disease 10 for glaucoma. Crude incidence rates were calculated and adjusted for sex, age, and gender. The 2020 incidence was compared with estimated rates from previous years to assess the impact of the coronavirus disease 2019 lockdown. A standardised morbidity map was created to show regional variations. The average incidence of glaucoma in Colombia was 17.36 per 1,000 inhabitants, increasing from 12.29 in 2015 to 24.22 in 2019. Of the 212,700 reported cases, 60.75% were females. Primary open-angle glaucoma was the most prevalent type, with significant incidence in the elderly over 70 years of age, irrespective of sex. Bogotá, Antioquia, and Valle del Cauca had the highest numbers of new cases. The increasing incidence of glaucoma and its demographic and geographical variations necessitate the awareness of ophthalmologists and optometrists. This study emphasises the need for continuous monitoring, effective interventions, and developing healthcare strategies to address the escalating challenge of glaucoma in Colombia.
