Secular Institutes and the Life of Mary
Authors: Graef H.C.
Published: August 2024

The stimulating article of Fr Oswin Magrath's on Contemplative Secular Institutes has raised issues which must have been in many minds since the publication of the Constitution Provida Mater Ecclesia. After the priest and religious has spoken, a lay-person may perhaps be allowed to present the same idea from a different angle.

It was surely not without a special significance that the Constitution was issued on the Feast of the Purification of our Lady, and there can, indeed, be no better guide for ‘contemplatives in the world’ than she, who led the sublimest life of contemplation in the most humble circumstances, as what seemed to her neighbours a carpenter's wife in a small town. The Queen of contemplatives had no need to cut herself off from her fellow creatures in order to enjoy an unbroken communion with her Creator.
The Death of a Protestant
Authors:   Graf Helmuth James Von Moltke
Published: August 2024

My dear—To begin with the ending: at about three o'clock the sentence was read out: Moltke, death and deprivation of estate; Father Delp, the Jesuit, the same; Reisert and Speer, ditto; Fugger, three years’ penal servitude. The defence had their say, all of them really quite decent, nobody malicious. When it came to the last words of the accused, your husband was the only one to waive his right. The best of the sofound verdict is: that we ‘had no design of using violence’ is now established: established, that we made no slightest move towards organising, spoke with no single person about his or her taking on a post. All we did was to think, and not all of us did that, just Father Delp, S.J., Gerstenmaier and I, the others counting as passengers. And the thinking of these three men, their mere thoughts, are so disturbing to the National Socialists, that anything so contaminated must be wiped out.
Lux Mundi
Authors: Tauler John
Published: August 2024

The Gospel of this (Laetare) Sunday is tlie one which tells of Our Lord's feeding five thousand men with five barley loaves: John 6.

Ego sum lux mundi—I am the light of the world (John 8)

When our Lord addressed these and similar words to the Jews, he was contradicted and attacked by his hearers. They said, he is a Samaritan, he has a devil. In today's Gospel, on the contrary, it is recorded that after our Lord had miraculously fed the crowd with five loaves and two fishes, he was surrounded by the Jews who were enraptured with the great miracle, and they said: ‘This is truly the Prophet who is to come into the world'.

It has seemed to us opportune to speak briefly of that light which our Lord claimed to be. That light has enlightened all created lights. The sun, moon, stars, man's bodily senses, the intellectual light of reasonable creatures, in other words reason and intelligence draw their brilliance from it; by that light, all creatures are led and brought back to their origin. And if they did not. return to it, considered on their own without this true and essential light, they would assuredly be but thick darkness. Again our Lord said to every faithful soul: Give up your own light for my sake; compared to my light it is but darkness, the very opposite of my splendour.
The Suffering Servant
Authors: Schlegel Desmond
Published: August 2024

The author of the Acts of the Apostles tells how one day Philip the deacon was travelling south on the road from Jerusalem to Gaza. He caught up with an Ethiopian eunuch driving along the same way in his chariot, and, as he did so, he overheard him reading aloud to himself the prophecies of Isaias. Philip asked him whether he understood what he was reading, and the Ethiopian replied: ‘How could I understand unless someone tells me what it is all about?’ He had got as far as: ‘He was led away like a sheep to be slaughtered, like a lamb that is dumb before its shearer, he would not open his mouth. He was brought low and all his rights taken away; who shall tell the story of his age? His life is being cut off from the earth.’ Said the eunuch: ‘Who is the prophet speaking of here? himself, or someone else?’ Philip answered by telling him all about Jesus.
Modern Dislocations in Religious Life
Authors: Pepler Conrad
Published: August 2024

In order to see the modern needs of religious men and women in perspective we should sometimes look across the Christian monastic scene back to the natural origins of religious life in primitive and pre-Christian religions. These origins, although they do not include the supernatural vitality of a life dedicated to the following of Christ, have yet a fundamental bearing on the way religious behave throughout the ages. Grace builds on nature, and there are natural origins even for religious life, which thus has a specifically human character as well as a divine. After many hundreds of years’ progress in ways of life and of culture, there almost inevitably arises a threat of dislocation, when those living the traditional culture are severed from its roots. In the case of Monastic life (just as on a wider field of the whole Christian way of living), the many centuries of existence have led to a tremendous elaboration which can become in part artificial and with little natural support.
Errors About Nature and Grace
Authors: Barker Austin
Published: August 2024

We claim to take for granted in the purposes of this essay the central facts of Christ, his reality in history, his verifiable effect, and the chief truths of his life, as they were preserved at least till a generation ago among the divided sects in the break-up of Christendom, and as they are now, and for ever will be preserved, only by the Catholic Church. Thus the divinity of Christ is here assumed, and the doctrine of divine grace and merit which lie poured out upon mankind by his death; his identity with his mystical Body, the Church whose life is but an extension through time and space of his own Incarnate Being; and chiefly here the thesis of his vivifying and redemptive work in the minds and wills of the men who decisively accept his Church.

The anxiolytic effect of oxytocin (OXT) on psychosocial stress has been well documented, but the effectiveness under the interference of other factors still requires in-depth research. Previous studies have shown that nicotine addiction interacts with OXT on psychosocial stress on the behavioral level. However, the underlying neural mechanism of interaction between OXT and nicotine addiction on psychosocial stress has not been examined, and we conducted two experiments to reveal it. Firstly, after intranasal administration of randomized OXT or placebo (saline), a group of healthy participants (n = 27) and a group of smokers (n = 26) completed the Montreal Imaging Stress Task (MIST) in an MRI scanner. Secondly, a group of smokers (n = 22) was recruited to complete a transcranial direct current stimulation (tDCS) experiment, in which anodal tDCS was applied on subjects’ anterior right superior temporal gyrus (rSTG). In both experiment, subjective stress ratings, salivary cortisol samples and the amount of daily cigarette consumption were obtained from each participant. Analysis of variance were applied on both behavioral and neural data to examine the effects of OXT and nicotine addiction, and correlation analysis were used to examine relationships between neural and behavioral data. In first fMRI experiment, analysis of variance (ANOVA) revealed an interaction of OXT and nicotine addiction on subjective stress. In smokers, OXT failed to suppress the elevation of subjective stress and craving ratings after psychosocial stress. A voxel-wise ANOVA of fMRI data identified an interaction between OXT and nicotine addiction in anterior rSTG, and its functional connectivity with right middle frontal gyrus. Correlations between this functional connectivity and subjective psychosocial stress were also found abnormal in smokers. In second tDCS experiment, we found that under tDCS, OXT successfully suppressed the elevation of subjective stress and craving ratings after stress. In summary, we found that nicotine addiction blocked OXT’s anxiolytic on psychosocial stress, which was related to abnormalities in anterior rSTG. By applying anodal tDCS on anterior rSTG, OXT’s anxiolytic effect was restored in smokers. These findings will support further development on oxytocin’s intervention of psychosocial stress in nicotine addiction, and provides essential information for indicating OXT’s effectiveness.

Two-pore domain K+ (K2P) channel activity was previously thought to be controlled primarily via a selectivity filter (SF) gate. However, recent crystal structures of TASK-1 and TASK-2 revealed a lower gate at the cytoplasmic pore entrance. Here, we report functional evidence of such a lower gate in the K2P channel K2P17.1 (TALK-2, TASK-4). We identified compounds (drugs and lipids) and mutations that opened the lower gate allowing the fast modification of pore cysteine residues. Surprisingly, stimuli that directly target the SF gate (i.e., pHe., Rb+ permeation, membrane depolarization) also opened the cytoplasmic gate. Reciprocally, opening of the lower gate reduced the electric work to open the SF via voltage driven ion binding. Therefore, it appears that the SF is so rigidly locked into the TALK-2 protein structure that changes in ion occupancy can pry open a distant lower gate and, vice versa, opening of the lower gate concurrently promote SF gate opening. This concept might extent to other K+ channels that contain two gates (e.g., voltage-gated K+ channels) for which such a positive gate coupling has been suggested, but so far not directly demonstrated.

Published: August 2024

Upper gastrointestinal bleeding (UGIB) is a common cause of hospital admission worldwide and several risk scores have been developed to predict clinically relevant outcomes. Despite the geriatric population being a high-risk group, age is often overlooked in the assessment of many risk scores. In this study we aimed to compare the predictive accuracy of six pre-endoscopic risk scoring systems in a geriatric population hospitalised with UGIB. We conducted a multi-center cross-sectional study and recruited 136 patients, 67 of these were 65–81.9 years old (“< 82 years”), 69 were 82–100 years old (“≥ 82 years”). We performed six pre-endoscopic risk scores very commonly used in clinical practice (i.e. Glasgow-Blatchford Bleeding and its modified version, T-score, MAP(ASH), Canada–United Kingdom–Adelaide, AIMS65) in both age cohorts and compared their accuracy in relevant outcomes predictions: 30-days mortality since hospitalization, a composite outcome (need of red blood transfusions, endoscopic treatment, rebleeding) and length of hospital stay. T-score showed a significantly worse performance in mortality prediction in the “≥ 82 years” group (AUROC 0.53, 95% CI 0.27–0.75) compared to “< 82 years” group (AUROC 0.88, 95% CI 0.77–0.99). In the composite outcome prediction, except for T-score, younger participants had higher sensitivities than those in the “≥ 82 years” group. All risk scores showed low performances in the prediction of length of stay (AUROCs ≤ 0.70), and, except for CANUKA score, there was a significant difference in terms of accuracy among age cohorts. Most used UGIB risk scores have a low accuracy in the prediction of clinically relevant outcomes in the geriatric population; hence novel scores should account for age or advanced age in their assessment.

Published: August 2024

Context. Directional discontinuities (DDs) are common structures in the solar wind plasma and are among the most important discontinuities besides shock waves. The Parker Solar Probe and Solar Orbiter spacecraft currently provide whole new insight into the inner heliosphere in spatial coverage and timescales.

Aims. We search for DDs and classify them into subgroups of tangential (TD) and rotational (RD) discontinuities. The analysis of the DD thicknesses allows us to test different theories about their origin and evolution.

Methods. We applied an automatic algorithm to select discontinuities between heliocentric distances of 0.06–1.01 AU. The method uses the spatial rotation of the magnetic field to identify the DDs and minimum variance analysis to determine the normal vector of the discontinuity surface. A classification into TDs and RDs was carried out using the magnetic field data and the Walén test in both the spacecraft and the deHoffmann–Teller frame.

Results. With strict conditions, we found more than 140 000 DDs in the time intervals. We find that the spatial density of DDs decreases with increasing radial distance from the Sun in the innermost heliosphere. The comprehensive analysis revealed that most of the DD, for which the normal component of the magnetic field is small are in fact TDs, regardless of the jump in field magnitude. After the classification, we were able to determine the radial thickness evolution for the TDs and RDs separately. We found that the thickness of RDs decreases from 0.06 to 0.30 AU, and beyond this (0.30–1.01 AU) it increases with the local ion inertial length. This characteristic scaling is present for TDs throughout between 0.06 and 1.01 AU.

Conclusions. Our results give us a simple classification tool for future studies of DDs, that is based only on magnetic field measurements. After we analyzed the DD thickness, we observationally confirmed that RDs are produced by Alfvén-wave steepening, while the TDs are most likely the boundaries of flux tubes.
(Re)mind the gap: A hiatus in star formation history unveiled by APOGEE DR17
Authors: Spitoni E. , Matteucci F. , Gratton R. , Ratcliffe B. , Minchev I. , Cescutti G.
Published: August 2024

Context. Analysis of several spectroscopic surveys indicates the presence of a bimodality between the disc stars in the abundance ratio space of [α/Fe] versus [Fe/H]. The two stellar groups are commonly referred to as the high-α and low-α sequences. Some models capable of reproducing such a bimodality invoke the presence of a hiatus in the star formation history in our Galaxy, whereas other models explain the two sequences by means of stellar migration.

Aims. Our aim is to show that the existence of the gap in the star formation rate between high-α and low-α is evident in the stars of APOGEE DR17, if one plots [Fe/α] versus [α/H], confirming previous suggestions. We then try to interpret the data by means of detailed chemical models.

Methods. We compare the APOGEE DR17 red giant stars with the predictions of a detailed chemical evolution model based on the two-infall paradigm, taking into account also the possible accretion of dwarf satellites.

Results. The APOGEE DR17 abundance ratios [Fe/α] versus [α/H] exhibit a sharp increase in [Fe/α] at a nearly constant [α/H] (where α elements considered are Mg, Si, O) during the transition between the two disc phases. This observation strongly supports the hypothesis that a hiatus in star formation occurred during this evolutionary phase. Notably, the most pronounced growth in the [Fe/α] versus [α/H] relation is observed for oxygen, as this element is exclusively synthesised in core-collapse supernovae. The revised version of the two-infall chemical evolution model proposed in this study reproduces the APOGEE DR17 abundance ratios better than before. Particularly noteworthy is the model’s ability to predict the hiatus in the star formation between the two infalls of gas, which form the thick and thin disc, respectively, and thus generate abundance ratios compatible with APOGEE DR17 data.

Conclusions. We show that the signature of a hiatus in the star formation is imprinted in the APOGEE DR17 abundance ratios. A chemical model predicting a pause in the star formation of a duration of roughly 3.5 Gyr, and in which the high-α disc starts forming from pre-enriched gas by a previous encounter with a dwarf galaxy, could well explain the observations

Published: August 2024

Whether the post-harvest process will greatly influence volatile or non-volatile coffee chemical compounds. Four post-harvest coffee processing techniques, namely natural, honey, fullwash, and wine, were evaluated in this study. This research aims to authenticate the volatile and non-volatile compounds of Robusta Jawa Bogor green bean as a differentiator in natural, fullwash, honey, and wine processing. Using HS-SPME-GC-MS and LC-MS, we identified a total of 128 volatile compounds (113 in natural, 111 in honey, 100 in fullwash, and 126 in wine), as well as 105 non-volatile compounds (77 in natural, 73 in honey, 66 in fullwash, and 93 in wine). The study found volatile compounds like ethyl cinnamate potential marker for honey processing. A potential marker for natural and wine processing is 1- isopropyl-3 methylbenzene. Some potential markers for wine processing are (E)-4-hexen-1-ol, 5-methyl-2-hexanol, diethyl succinate, ketoisophorone, and 4-ethyl-2-methoxyphenol. Non-volatile compounds like 1-naphthoic, [4]-gingerol, and theophylline are non-volatile markers for natural processing. Succinic acid is a non-volatile marker for natural and wine processing. While maleic acid and adenosine are markers for honey processing, adenine is a marker for wine processing. In contrast, fullwash does not have any volatile and non-volatile marker. Due to post-harvest-process variations, the obtained results assist in authenticating the chemical compounds of Robusta Java Bogor green beans.
Maximum Entropy Modelling for Sumatran Orangutan Habitat Suitability in Ketambe Research Station
Authors: Islamidini Nurul , Zumaidar Zumaidar , Sulistiyono Nurdin , Alfarabi Muhammad
Published: August 2024

This research aims to examine the spatial influence on the presence of orangutans. The study models four significant environmental variables: distance from food trees, distance from rivers, elevation, and slope, using the Maximum Entropy (Maxent) software with 10 replications. The results indicate that the environmental factor with the most substantial impact on the presence of orangutans is the proximity to food trees, contributing 90.9%. On the other hand, rivers, elevation, and slope contribute minimally to the modelling. Rivers are recognized as a determinant for orangutan nest presence, given their role as a vital life source for the forest ecosystem. However, in this modelling, the distance from rivers has limited impact due to the prevalence of numerous small rivers throughout the research area. Elevation and slope play a supportive role with modest influence, attributed to orangutans' arboreal nature. These models identify areas sharing similar environmental variables with locations where orangutans are found, suggesting that conditions matching these variables are suitable for orangutans. The habitat highly suitable for Sumatran orangutans encompasses an area of 17.43 hectares (4.14%).

Published: August 2024

Oil palm has a high potential for nutrient use efficiency, meaning it can produce high yields with relatively low nutrient inputs compared to other crops. Nutrient use efficiency is significant for nutrient balance and supply, like Nitrogen (N) and Potassium (K), which are vital for oil palm growth and fruit production. Research includes breeding for traits that enhance nutrient uptake and utilization and developing new fertilizer formulations and application techniques. This research aimed to investigate the response of some oil palm genetic backgrounds to the application of fertilizer level. The study was organized using randomized block design with two factors: fertilizer dosage [0% (P0), 100% (P1), 75% (P2), and 50% (P3) of the recommended dosage], and plant material [populations 1-3 (V1-V3)], repeated six times. The treatment of providing fertilizer doses at 50% of the recommendation (P3) shows more efficient and positive effect in the oil palm seedling growth. Population V2, given the treatment of fertilizer doses at 50% of the recommendation (P3), shows more efficient and positive responses in the oil palm seedling growth.

Published: August 2024

The local farmers have long implemented agroforestry systems, and many challenges are found in agroforestry practices. This study analyzed the plant species composition and local farmers' perceptions of agroforestry practices in Aceh and Java, Indonesia. We interviewed the local farmers and observed the species composition in the field. Most local farmers are in the 46-55-year-old age group (42%) with an elementary school education background (39%). Local farmers reported acquiring their agroforestry skills through self-experimentation. Most local farmers possess 2-5 years of experience. Only 29% of the farmers have participated in such groups or communities. Approximately 88% of local farmers have agrisilviculture as their preferred approach. They perceive their planted species' growth performance as in good condition (58%). The dominant tree species favored by local farmers are Tectona grandis, Falcataria falcata, Swietenia macrophylla, and Durio zibethinus. While in the realm of crops, the dominants are Manihot esculenta, Ipomoea batatas, Musa paradisiaca, and Capsicum annum. The main challenges faced by the local farmers are pest/disease attacks (43,9%), limited human resources availability (31,7%), and limited market (24,4%). The most needed in agroforestry practices are species selection (29,3%), cultivation techniques (24,4%), and irrigation systems (19,5%).

Published: August 2024

Sustainable development goals (SDGs) aim to reduce poverty by providing farmers with the widest possible access to information. Farmers’ limited access to information has resulted in poor digital literacy regarding the use of digital technology. The digital literacy gap occurs when the use of digital technology does not provide useful results due to the low skills of digital farmers, resulting in gaps in farmers’ participation in development. The results of this study found a solution to overcome the digital literacy gap through a social media approach through social systems. This route connects farmers with the farming community on social media so that it can encourage changes in farmer behavior, namely, willingness to market ornamental plants via social media. This study aims to determine the factors that influence the use of social media for e-commerce on farmers' behavior in using social media for e-commerce. This study used a survey method with a cross-sectional approach (research carried out once at a certain time). Data analysts use PLS-SEM version 3.0, which is supported by interview results. The research sample consisted of 210 randomly selected farmers who had smartphones and sold ornamental plants on social media.
Utilization Of used oil into biodiesel by using duck bone catalyst to meet the needs of diesel fuel review
Authors: Indrianty Irma Amaliah , Suhardi  , Muchtar Masjono
Published: August 2024

The growing need for oil presents a difficulty necessitates finding alternative energy sources. Since petroleum is a non-renewable resource, it requires millions, or even hundreds of millions of years to undergo transformation its raw materials into usable petroleum, the increase in the amount of petroleum consumption causes depletion of the amount of petroleum, potentially causing an energy crisis in the future. One solution is to process waste cooking oil into biodiesel as a substitute for diesel fuel. In order to generate superior biodiesel with relatively elevated quality, an investigation was conducted on the use of CaO as a solution purifier from impurities, separating glycerol and methyl ester. Most interestingly, Biodiesel can be used in existing diesel engines with minimal to no adjustments and little loss of performance. Most studies suggest that incorporating sufficient oxygen in biodiesel significantly reduces exhaust emissions.

Published: August 2024

The development of agricultural production requires the creation of conditions for increasing labor productivity, which is accompanied by an increase in energy consumption and, above all, an increase in heat and power engineering, which is one of the decisive conditions for the development of agriculture and its transfer to an industrial basis. The increase in the need for energy resources raises the problem of creating efficient and economical equipment for the agro-industrial complex. Successful solution to the problems of increasing poultry productivity is possible subject to the introduction of intensive rearing technologies. The industrialization of poultry farming, with the intensive use of production buildings, places qualitatively new demands on the indoor air environment, therefore, without creating and maintaining an optimal microclimate, it is difficult to obtain high poultry productivity even with proper feeding, care and well-organized breeding work. Temperature, relative humidity and air speed are the main parameters that determine the physiological state and productivity of poultry. Thus, by changing microclimate parameters one can definitely influence the bird’s body and help increase productivity.

This study emphasizes the global drive towards sustainable agricultural practices and the mounting pressure on agribusinesses to adopt eco-friendly and sustainable methods. This transition is crucial not only to meet evolving market demands but also to minimize environmental impacts and support broader goals of ecological responsibility and resource conservation. Focusing on the relationship between green machines and sustainability in South-West Nigeria's agribusinesses, the research utilized a quantitative approach, surveying registered members of the All Farmers Association of Nigeria (AFAN) across Ekiti, Lagos, Ogun, Osun, Oyo, and Ondo using cluster and purposive sampling techniques. With 353 completed questionnaires and an 87% response rate, analysis through measurement and structural models revealed that green machines significantly enhance the sustainability of agribusinesses in Southwest Nigeria. The findings underscore that integrating green machines in production is a pivotal driver for sustainable practices within the region's agro-industry. Agribusinesses are increasingly adopting green production practices to optimize resource usage, reduce emissions, and promote responsible land use, aligning with global sustainability trends. Consequently, adopting green machines in the production phase is vital for ensuring the sustainability and ecological responsibility of agribusinesses in Southwest Nigeria, benefiting both the industry and the environment. The implications of this study suggest that further promotion and support for green technology adoption could significantly advance the sustainable development of agribusinesses in Nigeria.

Published: August 2024

This research employs advanced numerical analysis using the Coupled Eulerian-Lagrangian Finite-Element method to evaluate the blast resistance of an underground steel pipeline subjected to surface and subsurface detonations. A pipeline model, reflecting standard gas and oil infrastructure, was created in Abaqus with a 1-meter external diameter, 10-millimeter wall thickness, and 12-meter length, buried 2 meters deep in brown clayey soil. The study applies various constitutive models, including Simplified Johnson-Cook Plasticity for the pipeline, Jones-Wilkins-Lee EOS for TNT, ideal gas EOS for air, and Mohr-Coulomb Plasticity for the soil. Results reveal that subsurface explosions severely compromise the pipeline's structural integrity, causing concentrated stress and displacement, while surface explosions produce broader, less severe effects. The study highlights the need for further research on the impact of water on pipeline resilience in different environments.

Initially, the NREL model of the 5 MW-net wind turbine model was adapted and then scaled down to simplify the numerical analysis and for the convenience of future experimental study. The analysis was conducted using the Finite Element Modelling software Abaqus. To ensure the validity of the FEM modelling, the benchmarking study is conducted by referring to previously published work. The case configuration was developed by varying the material properties of the tower (high, medium, and low carbon steels) and the material properties of the tower due to the effect of the site temperature. The results obtained show that high carbon steel has the best properties for use in wind turbine structures. At -80 °C, this is the temperature condition where AH32 material has the best properties.

The sharp increase of information in our life and in particular in agriculture leads to the development and new opportunities that did not exist a couple of decades ago. At the same time the ability to collect and analyze large volumes of data from remote sensing sources has revolutionized the way farmers make decisions and manage their agricultural activities. The great role in this process corresponds to Big Data, which is not only the data in itself, but a set of strategies for analysis that allow you to benefit from owning it. The goal of this study is to review published articles on big data in agriculture throughout 2017–2023. In line with this goal, we have collected (using Science direct database), reviewed, and analyzed 60 papers published during within this period of time. Our results revealed an increasing number of big data studies during last years, with authors from India, the USA and China dominating in the published outcomes (42 % of total), followed by authors from Australia, Canada and the Netherlands. Another key finding is that from all existing variables for big data only five are really important and there is no need to expand these parameters. It is more optimal to use main variables (volume, velocity, variety, veracity and value) for an in-depth and detailed description of the state of the data. Results also revealed different big data sources and techniques for mail areas of data application.

The research revealed significant differences in the technological indicators of silk cocoons grown with mulberry leaves from special plantations in the foothills of Uzbekistan compared to those from plantations on saline lands. The silk cocoons from the foothill plantations showed much higher technological indicators. This finding validates the conclusion that establishing special mulberry plantations on newly reclaimed land areas in the foothills not only enhances the feed base for sericulture but also contributes to the protection of agricultural crops from erosion and other forms of land degradation. These results highlight the importance of strategic planning and sustainable land use practices in agricultural development. By focusing on establishing mulberry plantations in suitable regions, such as foothill areas, policymakers and stakeholders can not only enhance silk production but also contribute to environmental conservation and the protection of agricultural lands. This research provides valuable insights for policymakers and agricultural stakeholders seeking to promote sustainable sericulture practices and mitigate the impact of land degradation.

The effectiveness of controlling polysis aphids and greenhouse orthoptera using a suspension of P.varioti's strain EMR-57 and insecticide Fufanon was evaluated in a tomato-planted greenhouse. The study found that the mortality rate of polysis aphids reached 57.8% within 3 days and 67.6% within 14 days when the P.varioti's strain EMR-57 suspension with a titer of 6·107 cfu/ml was applied. In the case of greenhouse orthoptera, the mortality rate was 60.0% and 78.8% within the same respective time frames. Contrastingly, in the water-sprinkled version, the mortality rate was significantly lower, with only 2.6% mortality within 3 days and 4.3% and 3.3% in 1 and 7 days, respectively. This indicates that the P.varioti's strain EMR-57 suspension is more effective when directly applied to the target pests compared to a general water-sprinkled application. In greenhouse conditions, the most optimal rates for controlling both pests were found to be the combination of 2.5 L/ha of Fufanon insecticide, 6·107 cfu/ml titer of P.varioti strain EMR-57, and 0.04% concentration of "Selver" adhesive active substance. This combination showed effective control of both polysis aphids and greenhouse orthoptera, highlighting its potential for integrated pest management strategies in greenhouse agriculture.

The research conducted on the pathogen Theileria annulata, which causes tropical theileriosis, has provided valuable insights into its behavior and virulence under various environmental conditions. The studies, which involved isolates from Azerbaijan, Tajikistan, the North Caucasus, and different regions of Uzbekistan, have shown that environmental factors such as temperature and humidity play a significant role in the pathogen's virulence. One key finding is that unfavorable environmental conditions can lead to changes in the virulent properties of Theileria annulata. For example, high temperatures and low humidity may weaken the pathogen, making it less virulent. Conversely, certain conditions could strengthen the pathogen, increasing its virulence and pathogenicity. Additionally, the passage of the pathogen through highly susceptible animals can also influence its virulence. Through these processes, the pathogen undergoes genetic and phenotypic changes that impact its ability to cause disease in animals. Understanding these factors is crucial for developing effective control and prevention strategies against tropical theileriosis. By studying the behavior and virulence of Theileria annulata under different conditions, researchers can identify potential risk factors and develop targeted interventions to mitigate the impact of the disease on livestock populations.

Sometimes there is a concept that once applying fertilizer mean there is a good harvest. But it is not. When the soil phases are found crops there is a change in the ratio of nutrients. This ratio is of great importance in the development of these elements. With the help of science - based management to form the ratio of elements in the soil, you can get the expected and high-quality harvest. The use of seeds in different varieties of winter wheat not only increases the yield, but also improves the quality of grain. When developing a mechanism for improving the quality of grain, it is necessary to take into account the genotypic characteristics of varieties. Different varieties have their own reactions due to their different needs for the nutrient medium in the soil [1–4].

The research focuses on analyzing recent data concerning the socio-hygienic and ecological impacts of automobile exhaust emissions on human health and the environment in modern cities, with a specific focus on atmospheric air quality in Tashkent, Uzbekistan. With the prolonged use of motor vehicles in the USA, Europe, Asia, and notably in Uzbekistan, questions have arisen regarding the effectiveness and repercussions of transportation policies on the environment, health, and society. Thus, the primary objective is to contribute to the development of alternative transportation modes that are environmentally and health-friendly, aiming to mitigate the adverse effects of transportation systems on human health. The study utilized methods for measuring carbon monoxide and hydrocarbon levels in exhaust gases, adhering to national standards. When evaluating environmental pollution in cities with complex pollution sources, relying solely on harmful substance concentrations is insufficient. In such scenarios, the population's health level, as determined through socio-hygienic and ecological monitoring, serves as the primary criterion for assessing the environmental condition. Field studies of exhaust emissions were conducted throughout Tashkent city and its districts, encompassing all major parameters.
