This paper analyses the types of innovation intermediaries that have emerged in Mongolia and investigates their roles within the information technology sector of the country. The study finds that diverse innovation intermediaries have emerged, and the majority of the intermediaries are non-sector specific, with only a few specializing in a single industry. The sector-specific intermediary plays a crucial role in building linkages and providing access to resources in sectoral innovation systems in developing countries. The study identifies several constraints related to funding and innovation policy support for these intermediaries. Consistent policy and financial support for sector-specific intermediary organizations could strengthen their role in the developing countries, particularly those with limited human and capital resources, such as Mongolia. This study contributes to an important understanding of the roles of intermediaries in underdeveloped and newly developed immature innovation systems of developing countries with low income and limited resources. As for the innovation system of Mongolia, it is impending to strengthen the sector-specific intermediary organizations through government and budgetary support and training for specialized human resources. The study also provides valuable insights that can guide the future development of the industry.

The purpose of this study is to improve the content and methodologies of the curriculum of the training courses for the development of the speed ability of high school students, who practice basketball. When developing the speed capacity of the high school students of National Secondary School of Horinger country of Hohhot, Inner Mongolia, People's Republic of China, a Chinese researcher Li Wenlong (2015) used the theory and concept that "an important part of training of basketball players is to develop their speed capacity by improving their strength capacity." Movement test methodology was used to determine the general speed ability of the students and the basic technical speed level of basketball and consequently, to calculate the results [3]. A program developed to study respondents' general speed and basketball speed revealed that a 30-meter run was improved by 0.51 sec, 50-meter run by 0.72 sec, and 100-meter run by 0.36 sec. According to the basic technical parameters of basketball, the speed during straight dribbling increased by 0.56 seconds, the dibbling speed around the 15 mark increased by 0.38 seconds, the speed of two students running and passing ball on a 28-meter court increased by 0.78 seconds, and the speed of the defensive transition improved by 4 times. We believe that the capacity of targeted exercises, tools, and exercise selection in the curriculum and planning models used in our study have become efficient.

Mentha arvensis L. is well known for producing the monoterpenes menthol; its essential oil (EO) is widely used in pharmaceutics, cosmetics, food and other industries. The peltate glandular trichome (PGT) is the site responsible for the production and storage of EO in mint. Light is one of the most important environmental factors that contributes to plant growth and development, and secondary metabolism. In this report, we have investigated the influence of additional red light (White + Red, W+R) and blue light (White + Blue, W+B) on the parameters of growth, EO, and PGT in M. arvensis. Interestingly, the plant growth parameters, such as the number of branches, plant height, fresh weight, leaf area and number of leaves were significantly greater both under W+R and W+B treatments compared to the control group. Red light proved more beneficial for increasing plant height (by 15.26%) and fresh weight (by 58.42%), whereas blue light was more effective in boosting the number of branches (by 83.68%) and leaves (by 65.07%). The highest increases in essential oil (EO) content (by 36.36%), yield (by 101.72%), and peltate glandular trichome (PGT) density (by 35.64%) were observed under W+B treatment. However, both W+R and W+B had a slightly negative effect on the quality of mint EO, where menthol content decreased by 4.32 per cent and 11.88 per cent respectively. These results proved that red light is more conducive to biomass accumulation, while blue light is more conducive to EO synthesis and PGT development in M. arvensis.

The experimental study aimed at identifying the effects on soil fertility and resources using five different treatments, fallow, non-cultivated land, serial plants, leguminous plants, and grass, was conducted in a central agricultural region of Mongolia. The findings highlight the beneficial effects of cooperative agriculture for food and fodder on the restoration of soil fertility and its resulting useful effect on wheat crop yield. To ensure the stability of soil fertility in the central agricultural region, the key results of the suggest that mobile macro element nitrogen in the soil increased by 45-75.9 per cent over a 3-year rotation with spring soft wheat as the major crop grown along with leguminous plants. Furthermore, the implementation of a two-year rotation of Melilotus albus as intercropping for fodder and food purposes has been found to enhance the rate of soil cellulose decomposition. Furthermore, it has been observed that the continuation of favorable weather conditions and availability of moisture directly correlate with the extent of cellulose decomposition. The aggregate structure of the soil with a diameter of 1-3 mm, which is crucial for growing perennial grass (Agropyron cristatum), is improved by 11.87 per cent to enhance the field's soil structure and reduce erosion. In our research, it was found that legumes have a high protein content and are important role in meeting the needs of livestock and human food, while enriching the soil with nitrogen and increasing the yield of other crops. However, the practical importance of our research lies in the fact that it was established that perennial plants improve the structure of the soil. Legumes, according to our research, are rich in protein and contribute significantly to the provision of food for humans and livestock, as well as to the enhancement of soil nitrogen levels and the growth of other crops. Nevertheless, our study holds practical significance because it proves that grasses enhance the soil's structure as well.

This paper is devoted to the production of π-and K0 mesons from π-+p→π-+X and π-+C→π-,K0+X interactions at 40 GeV/c as a function of the square of four momentum transfer. The cut parameter of the strong coupling constant is taken as Λac2=ma2+mc2. Values of the strong coupling constant are then compared to leading-order and next-to-leading-order perturbative QCD calculations for the first time. Agreement between the experimental data and theory is good, thus providing a precision test of QCD at large momentum transfers (q). The strong coupling constant αs is extracted as a function of q, showing a good agreement with the renormalisation group equation and with previous analyses. As the momentum transfers increases, the running coupling constant decreases. For each high-energy interaction, a quantity called the cut parameter is chosen differently depending on the secondary particles produced by the reaction. For each high-energy interaction, a quantity called the cut parameter is chosen differently depending on the secondary particles produced by the reaction.

In this study, seasonal characteristics of aerosol optical properties at Ulaanbaatar station of the international network of SKYNET are investigated using ground-based skyradiometer from the years extending from 2017 to 2023. The aerosol optical thickness (AOT) at 500nm wavelength and Angstrom exponent (AE) were determined in winter to evaluate the decrease in air pollution in Ulaanbaatar since implementing the government's decision to use coal briquettes for household heating. During the study period, the monthly mean AOT at 500nm varied throughout the year, with the maximum value of 0.178±0.004 obtained in winter due to households burning large amounts of biomass, and the highest AOT (0.183) was obtained in February. The mean AOT was 0.21 in the winter of 2017-2019, which decreased by 15 per cent to 0.18 in the winter of 2019-2023.

The national food security system in our country is not established well and continues to remain weak. Failures within the system have caused malfunctions and distortions in government policy implementation, leading to unexpected policy shifts. These faults are the main causes of time loss, inter-agency misunderstandings, lack of coordination, information flow deficiencies, and a shortage of skilled human resources. These issues can have a negative impact on food security in Mongolia, resulting in the shortfall of government policy implementation. Coordination of food security activities among government organizations in Mongolia has been unsatisfactory due to the weak system. Government services have not adequately reached organizations at the middle and primary levels in the Mongolian rural provinces. This research paper aims to evaluate the national food security situation based on policies in Mongolia's food sector over the past decade, their implementation, encountered problems, and involved stakeholders. The research findings show that our country's food security system is not well-established, leading to compromised food security, highlighting the urgent need for developing necessary legal and policy documents to effectively implement state food security policy.

We address the sequence of Sun-to-Earth phenomena, that enables to study the mechanism for geoefficiency of eruptive prominences propagating from the Sun inside coronal mass ejections (CMEs). An eruptive prominence ejected in the solar wind (SW) moves at the SW velocity Earthward like adiamagnetic structure of eruptive prominence (DSEP).The key feature of the latter is a largesharp plasma concentration jump N inside the DSEP at a simultaneous sharp drop in the interplanetary magnetic field (IMF) modulus B. It is the anti-correlation between the N and B profiles in DSEP, due to which its contact with the magnetosphere may lead not only to magnetosphere compression, but also to penetration of DSEP substance into the magnetosphere. The duration of the magnetospheric disturbance (in the form of dayside auroras), global increase in the current systems, charged particle flux enhancement in the radiation belts, and generation of the irregular Pi2-3 oscillations aredetermined by the DSEP size. We present statistical investigations into DSEPs observed in different years of solar activity and builta qualitative modelfor DSEP geoefficiency.
