Authors: Yakhnik Yana , Volkova Galina , Danilova Anastasia , Kutumov Kirill
Published: November 2024

Background: Currently, cultivar mixtures are being extensively used in agriculture worldwide. The current research study aimed to identify the optimal proportion of cultivars with different resistance to pathogens to reduce the severity of leaf diseases in mixed cultivars against net blotch and leaf rust of barley.Methods: Leaf rust severity was assessed using a modified Cobb scale, and net blotch severity with the E. E. Geshele scale. Disease severity was averaged from triplicate measurements on 25–30 plants. After harvest, 1000 seeds per plot were weighed. Differences were evaluated using the Fisher test (α = 0.05), and correlations via the Chaddock scale in Statistica 13.3.Results: A high degree of inverse correlation was established between the proportion of resistant cultivars and the severity by both diseases r= – 0.93/– 0.99. The optimal mixture combination of a resistant and susceptible cultivar against net blotch was recorded as 1S:4R, and leaf rust as 1S:3R and 1S:4R.Conclusion: In mixed barley crops, a strong inverse correlation was found between the proportion of resistant cultivars and disease severity (r = –0.93/–0.99). Disease severity correlated directly with humidity and temperature in spring, with an inverse correlation for net blotch in June. Using mixed cultivars enhances crop resistance to abiotic and biotic stresses, making it suitable for eco-friendly farming.Keywords: Abiotic factors; Barley; Mixture of cultivars; Puccinia hordei; Pyrenophora teres

Based on the Global Self-Consistent Model of the Thermosphere, Ionosphere and Protonosphere (GSM TIP), the response of the regional electron content of the ionosphere (REC) at high latitudes was calculated for the storm of March 17, 2015 and for an isolated reference geomagnetic AE storm obtained by averaging the AE index variation using the superposition of epochs with key moments corresponding to the AE index maximum. In this paper, the contribution of three altitude intervals (80–300 km, 300–800 km and 800–20000 km) to the response of high-latitude REC to geomagnetic storms will be considered.

The paper demonstrates the results of numerical modeling of the propagation of acoustic and internal gravity waves propagating from the troposphere using the numerical regional high-resolution atmospheric model AtmoSym and the Global Self-Consistent Model of the Thermosphere, Ionosphere and Protonosphere (GSM TIP). It is shown that the most important mechanism determining the change in the spatial structure of TEC perturbations under the influence of atmospheric waves is perturbations of the thermospheric wind components. It is shown that the propagation of atmospheric waves affects the change of the electric field and leads to the magnetoconjugate effect.

Wave disturbances play a significant role in the dynamics of the Earth's atmosphere. By studying wave disturbances in the upper atmosphere, it is possible to estimate the amount of energy transferred from the lower atmosphere to the upper atmosphere and subsequently evaluate, for example, the influence of processes in the lower atmosphere on the dynamics of artificial Earth satellites. For the south of Eastern Siberia, a statistical analysis of wave disturbances at 557.7 nm intensity - the atomic oxygen emission line (altitude ~85–115 km) was carried out using optical instruments of the National Heliogeophysical Complex.

We present an analysis of the observation of a series of ultra-low frequency (ULF) waves using data from the Van Allen Probe A satellite. The event was observed on February 15, 2014 on the dayside magnetosphere. Two types of ULF waves were registered. The first was compressional ULF wave with a frequency of about 2 mHz and an amplitude of about 3 nT. The second one was an Alfven wave with a frequency of about 6.5 mHz. It is shown that the compressional wave was generated during drift resonance with electrons with about 90 keV, and the poloidal wave was generated during bounce-drift resonance with proton fluxes with energies in the range of 150 keV. The parameters of the observed waves and the mechanism of their generation were determined.

This study investigates fluctuations of the magnetic field in the magnetosheath and geomagnetic pulsations in the magnetotail in the range of 1–5 mHz (Pc5/Pi3). According to the data of magnetic measurements on the Cluster satellites in 2016, the dependence of the spectral coherence of magnetic field variations on the length of the interval is considered for different locations of the satellites relative to the magnetopause. It is shown that the decrease in coherence with increasing interval length T is approximately the same for the magnetotail and the magnetosheath at T ≤64 minutes, and at larger values of T, the coherence in the magnetosheath decreases faster than in the magnetotail.

Cirrus clouds have been the subject of active study in recent decades. However, their influence on solar radiation transfer in the Earth's atmosphere and, consequently, on the planet's climate, has not been sufficiently explored. Space lidars, such as the CALIPSO and EarthCARE, are the primary tools used to study cirrus clouds through active remote sensing. However, interpreting lidar data poses a challenging problem in atmospheric optics. The main obstacle in interpreting lidar data is the lack of a complete solution to the direct problem of light scattering on ice crystal particles of cirrus clouds. This report presents a solution to the problem of light scattering for ice crystal particles commonly found in cirrus clouds, including hexagonal plates and columns, droxtals, and particles of arbitrary shape. The particle sizes ranged from 10 to 1000 µm, and the calculations were performed for six wavelengths 0.355, 0.532, 1.064, 1.55, 2 and 2.15 µm. The solution is presented as a databank of backscattering Mueller matrices.

This study investigated the relationship between screen time and myopia in children aged 5-12 years in Ibadan South-west Local Government, Nigeria. Guided by three specific purposes and research questions, the study examined how screen exposure, parental behaviors, and socioeconomic status influenced the development of myopia in young children. A descriptive survey research design was adopted. A sample of 300 children aged 5-12 years was selected from primary schools using a multistage sampling method.
Two main instruments were used for data collection: a structured questionnaire for parents and an eye examination for children. The questionnaire was reviewed by experts in child health, education, and visual health to ensure content validity. The test-retest method was employed to establish reliability, with a Cronbach’s alpha coefficient of 0.70. Data were analyzed using descriptive statistics, including frequency counts, percentages, means, and standard deviations, to summarize demographic data, screen time duration, and the prevalence of myopia among participants.
The findings revealed that prolonged screen time was significantly associated with higher rates of myopia among children. Children exposed to more than 2 hours of screen time daily had a higher prevalence of myopia. Passive screen activities, such as watching television, were found to have a stronger association with myopia than active screen use, like educational or interactive activities. Parental behaviors and lower socioeconomic status were also linked to increased screen exposure and higher rates of myopia.
The study concluded that excessive screen time poses a significant risk for myopia in children and highlighted the need for public health interventions and parental education to manage screen time effectively and support healthier visual development.

Many countries in Southeast Asia have used technological spillovers from textile and apparel related Foreign Direct Investment (FDI) to industrialise and diversify their economies and integrate their markets to the global economy. In a bid to promote similar industrial activities in sub-Saharan Africa (SSA), the African Growth Opportunity Act (AGOA) was implemented by the American government in 2000 to give countries in SSA tariff free access to American markets on specific products, including textiles and apparels. While few SSA based countries have utilised this opportunity to attract textile and apparel related FDI, create employment and grow exports to the US, even fewer have benefited from spillovers. This study prescribes policy options for SSA countries to attract textile and apparel related FDI and how technological spillovers can be obtained from such activities. The study revealed that an Export Processing Zone and an East/South Asian connection established before the implementation of the AGOA, low cost of inputs and good industrial relations served as magnets for FDI. The study also revealed that the lack of local ownership of textile and apparel firms and mid-level management skills in the SSA countries, the nature of the locating firms and restriction of global value functions to production by the foreign firms were obstacles to FDI spillovers. The study recommends promoting the establishment of local firms and situating them in proximity to foreign firms, skills upgrading of the local labour force especially in upstream value chain functions, promoting backward and forward linkages with foreign firms and encouraging FDI by large multi-national textile and apparel firms rather than small family-owned businesses.

The introduction of the Trade Related Aspects of Intellectual Properties (TRIPS) Agreement has limited the access of developing countries like Nigeria to technologies critical for national development aspirations. Little attention has however been given to identifying the flexibilities that can be exploited in the Agreement. This study examines Nigeria’s technology-driven socio-economic development aspirations, analyzed the TRIPS Agreement and its impact on technology-driven sustainable national development planning and identified flexibilities in the Agreement that could be utilized for enhanced access to technologies. The study utilized content analysis methodology and relied on sources of information which include Nigerian legislation and International conventions and treaties. The study revealed the flexibilities that Nigeria could use to enhance access to technologies for development. This includes compulsory licences, parallel imports and exemptions to patentability among others. Furthermore, the study revealed that the application of these flexibilities was not automatic but developing countries had to take advantage of them by amending their laws and putting in place appropriate policies to exploit them. The study concluded that until attention is given to the flexibilities within the TRIPS Agreement, the Agreement would continue to be perceived in Nigeria and other developed countries as a barrier to access appropriate technologies for national development.

There is global awareness of the tremendous impact technology transfer can make on economic development. Successive Nigerian governments being fully aware of this, have made concerted efforts over the years towards transferring foreign and locally developed technologies to user-industries. Unfortunately, these efforts have not yielded the desired results. This study investigates the efforts of the Federal Institute of Industrial Research, Oshodi (FIIRO) in its bid to transfer locally developed technologies to user industries since the 1980s and why those efforts have not been effective. The study reveals that strategies employed by the Institute include training workshops, technical assistance services, licensing and sponsored research. The study also showed that factors impeding Nigeria’s efforts in technology transfer include inadequate infrastructural support and funding of government research/allied institutions, stiff competition from foreign goods, lack of adequate political will and support by government, and poor remuneration of R&D and academic personnel among others. The study recommends adequate funding of technology transfer processes from the laboratory to the market and the protection of local industries from foreign competition among others.

The informal sector employs the largest share of labour in developing countries and it is considered to be a fertile ground for growing the technological capabilities needed for economic development. This study examined technological capabilities in the bread baking industry in Nigeria with a view to inform policy formulation. Data were collected on three constructs of technological capability namely; investment, production and linkage capabilities of the industry through questionnaire administration on 200 bakers. The results reveal strong production capabilities in the sector, albeit in using traditional production technologies. Investment and linkage capabilities were however shown to be weak. The former was due to the restriction of source of funding to personal savings, family members and cooperatives. Linkages with knowledge institutions such as universities, polytechnics and R&D institutions were also found to be very weak. These weaknesses may be the leading cause of being unable to purchase and use modern technologies in the sector effectively. The study concluded that the sector may be caught in the trap of being restricted to low-tech based production equipment. Recommendations include availing the industry access to innovative financial instruments to enhance access to funds and professional help in conducting feasibility studies to identify and acquire relevant modern technologies. In addition, setting up platforms for linkages with knowledge intensive institutions may enhance production capabilities in using new production processes and ease transition to utilizing modern technologies.

In a typical health care facility in Nigeria, pharmacy operations are laden with paper-based methods of documentation and routine tasks of medicine distribution. As a result, there are largely inadequate structures in place to monitor patients’ prescription history and prevent impersonations and fraud. This study presents the development of a web-based system (PharmaPortal) to manage medicine inventory and prescriptions at the healthcare facility of the Obafemi Awolowo University (OAU), Ile – Ife. PharmaPortal was implemented with PHP, MySQL, JavaScript and CSS on Apache web server. The software is browser-based and was made accessible at various workstations within the Local Area Network (LAN) of the healthcare facility. Routine activities in five sections of the healthcare facility were digitized into six modules with each containing closely related tasks and activities within the sections. The use of PharmaPortal was shown to enhance the speed of patients’ registration and information retrieval, as well as provide a simplified pharmacy inventory and prescription management. Most significantly, an evaluation of the system revealed an improved tracking of prescriptions through the use of patient identifiers which served to eliminate impersonation and reduce fraud.

In spite of the potential of marginal oil and gas fields to increase the level of petroleum production in Nigeria, very few indigenous producers have made appreciable progress. The envisaged development of indigenous technological capabilities has also not been realised. This study examines the capability building linkages among the relevant actors in the sector. Primary data was gathered by questionnaire administration on a sample of 120 lecturers in oil and gas related disciplines in Federal and State universities across Nigeria, 150 staff from indigenous oil and gas firms, 42 credit analysts in 21 commercial banks and 20 members of staff in relevant government agencies. The survey shows that collaboration between the oil and gas firms with Financial Institutions (2.50), Government Agencies (2.43) and Universities (2.31) was low. Regression analysis revealed that engaging academic staff in Consultancy, Student internships and industry sponsored conferences may improve linkages with academia. The study further shows that project financing credit, invoice discounting facilities and bank guarantees may enhance linkages with financial institutions while Government financial support for technology innovation and training, policy directed towards marginal field development and R&D funding may facilitate linkages with government agencies. The study concludes with a framework that may foster sustainable collaboration among stakeholders in the sector.

Aging is a phenomenon already identified in the last century, being called countless times as a misfortune, which resulted in some discussions, because if the years of life were prolonged, we should also foresee that there were no limitations in the quality of life, given that Aging is one of the greatest feats of modern humanity. Given this, the general objective of this study is to relate the practice of Gerontomotricity in the process of encouraging physical activity with a focus on the healthy aging process. To that end. we list the following specific objectives: identify the main changes resulting from the aging process that directly affect the functional autonomy of the elderly; evaluate the intervention of physical activity on the psychomotricity of the elderly and relate the benefits of the activities developed by the Gerontomotricity program in implementing a healthy aging process. The research is a literature review with a descriptive aspect and a qualitative approach. In the review, the following inclusion/exclusion factors were considered: articles published between 2020 and 2024 and that worked on the topic: Gerontomotricity and/or physical activities for the elderly. The research data revealed that active elderly people have less impaired motor skills, which results in healthy aging, with a great improvement in the ability to carry out their daily activities alone, which significantly reflects on the daily activities of the elderly. It is concluded, therefore, that the practice of continuous physical activities generates a noticeable improvement in the quality of life of the elderly, as it is combined with a set of methods with the objective of evaluating and determining the most recommended exercises for each individual, considering them. If all its particularities and aiming to meet the needs arising from the changes caused by the aging process, it results in significant changes in life, in the elderly gaining autonomy and coexistence with others.
