Published: July 2024

Purpose: Tele-eyecare is a form of tele-healthcare that engages in delivering eye care services to patients using telecommunications technology. This study aimed to assess the knowledge and attitude towards tele-eyecare among optometry students.
Methods: A convenience sampling technique was used to distribute pre-tested questionnaires to 268 students in pre-clinical and clinical classes of the Department of Optometry, University of Benin. The characteristics of the respondents were displayed using percentages and tables. The association between knowledge, attitude, and characteristics of respondents was tested using the Chi-square test.
Results: Among the respondents, 56.7% were females while 43.3% were less than 25 years of age. The majority of the respondents (92.6%) indicated that tele-eyecare involved the use of information and communication technology to provide eye care services. 86.6% of respondents believed that tele-eyecare can improve the quality and accessibility of eye care services while 75.4% agreed that tele-eyecare would benefit future eye care providers. Furthermore, 65% of respondents were interested in getting training on tele-eye care, age, gender, and year of study influenced the knowledge and attitude of the respondents (p<0.05).
Conclusion: The majority of the participants demonstrated good knowledge and a good attitude towards tele-eyecare, however, there is a need to close the tele-eye care knowledge gap among clinical optometry students.

Published: July 2024

Marfan syndrome (MFS) is an inherited disorder that affects the heart, joints, skeleton, skin, and eyes. People living with MFS are described as tall, long, slender built in appearance, with arachnodactyly, chest wall deformities, and scoliosis. A long, narrow face with deep-set eyes, down-slanting palpebral fissures, flat cheekbones, and a small chin are the facial features often found in people with MFS. The onset varies from infancy to all ages with most cases being diagnosed in the first two decades of life. In children, ocular findings are microspherophakia, congenital/infantile glaucoma, high refractive error at a young age, uveitis, retinal detachments, and enophthalmos secondary to the absence of retrobulbar fat. The basic management procedures include topical dilating agents for chronic dilation of the eye to increase pupillary size for aphakic correction, thorough and careful refraction, the use of contact lenses and/or glasses, removal of the dislocated lens, cataract surgery and treatment of amblyopia. Low vision assessments were carried out on the patients. The approach to the management of the two patients, whose cases are being reported, was different for each case and differed from conventional low vision management. Spectacle corrections of OD -20.00DS (1.76LogMar 6/36 near: 0.80M@23cm) and OD +7.5.0DS (6/9 1M@12cm) were issued for Cases 1 & 2 respectively. 8X Telescope (6/9) and magnifiers (4X Handheld N5 and spectacle +16 DS 0.50m/ N5) were recommended for cases 1 and 2 respectively. Low vision and rehabilitation were found to maximize visual functioning and are reliable options for MFS.

Published: July 2024

Background: Undernutrition is a major predisposing factor to common childhood infectious diseases. It contributes to about half of the deaths of children worldwide, especially in low-income countries. The prevalence of childhood undernutrition is still high despite implementing informed and directed interventional strategies. It is plausible some important aetiological factors may not yet be in focus.
Objective: To explore the relationship between acute diarrhoea and a history of recent hospitalisation for common childhood diseases and undernutrition.
Methods: This observational, cross-sectional study was conducted on 244 primary school pupils aged 6-12 years in Nnewi, southeast Nigeria. Socio-demographic and other relevant clinical details related to recent diarrhoeal episodes and hospitalisations were collected using an interviewer-administered questionnaire. The anthropometric parameters were used to determine the nutritional status using the World Health Organization (WHO) growth charts.
Results: More than half (133; 55.3%) of the participants were males, and most (106; 43.5%) belonged to the low socio-economic classes (SEC). More than half (135; 54.5%) were aged 6-8 years. Low SEC, acute diarrhoea and hospital admission in the preceding six weeks were significantly associated with undernutrition (p <0.001).
Conclusion: Acute diarrhoea and recent hospitalisation in the preceding six weeks were associated with undernutrition among primary school children in Nnewi, southeast Nigeria. Prompt treatment of acute diarrhoea to reduce its duration and prevention of common ailments that lead to hospitalisation may help reduce the incidence of childhood undernutrition.

Статья посвящена исследованию разубоживания руды. Выполнен подробный анализ существующих методов управления разубоживанием руды при отработке маломощных рудных тел системами с открытым очистным пространством. Оценена эффективность их использования в различных горно-геологических условиях. Особое внимание было обращено на результаты зарубежных исследователей. Проанализированы методы, способствующие снизить разубоживание руды при разработке маломощных залежей. Маломощные рудные тела, как правило, имеют сложную структуру с возможными раздувами и пережимами. При отработке маломощных рудных залежей системой подэтажного обрушения с торцевым выпуском руды вероятность снижения содержания полезного ископаемого увеличивается.
In the review article, a detailed analysis of existing methods for controlling ore dilution during the development of low-power ore bodies by systems with an open treatment space is carried out, the effectiveness of their use in various mining and geological conditions is evaluated. The scientific article is devoted to the study of ore dilution. Special attention was paid by the authors to the results of foreign researchers. The methods contributing to the reduction of ore dilution during the development of low-power deposits are analyzed. Low-power ore bodies, as a rule, have a complex structure with possible inflations and clamps. When working off low-power ore deposits with a system of a sub-storey collapse with an end release of ore, the probability of a decrease in the mineral content increases. For example, the actual dilution of ore at the Akbakai deposit of Altynalmas JSC reaches 70% or more.

The object of research is a multistage centrifugal pump for pumping water. The authors presented a method for hydrodynamic calculation of the flow kinematics in a centrifugal wheel, pressure characteristics of the pump. The calculations were carried out according to the passport data for the entire working area of the pump. In order to verify and verify the adequacy of the flow model, the results of pressure and efficiency factor were obtained experimentally on an automated hydraulic stand. The article presents a methodology for testing the pump and determining the measurement error. Calculation results are in satisfactory agreement with the passport data (within 3%). However, at low feeds, the real pressure characteristic has a «sinking» section, which is explained by manufacturing errors of the centrifugal wheel.

The paper presents the results of studying the modification of the specific surface area and porosity of pyrite and arsenopyrite during their thermal decomposition. It has been established that the decomposition of pyrite and arsenopyrite is accompanied by an increase in the pore volume from 0.303 10-3 to 1.23 10-3 with an increase in the degree of pyrite decomposition by about 41%, and then a decrease by about 0.131 10-3 m3/g. at a degree of decomposition of about 100%. The surface area of the pores increases from 0.31 to 1.085 m2/g with a subsequent decrease due to the coarsening and merging of small pores. An increase in porosity is accompanied by an increase in the aerodynamic resistance of particles resulting from increased dust formation of the furnace
В статье приведены результаты изучения модификации удельной поверхности и пористости пирита и арсенопирита при их термическом разложении.
