Authors: Vdovenko Sergiy , Shevchuk Victoria , Shevchuk Oksana , Dedov Alexander
Published: January 2022

Biostimulants are the kind of "doping", due to which crops gain great vitality for crop formation. Growth stimulating drugs make a positive effect on the soil microflora, they are rapidly transformed by soil microorganisms, plant cells. The aim of the work was to substantiate scientifically the use of stimulating growth regulators –Epin-extra, Agorostimulin, Rival, and Kornevin, as the elements of soybean growing technology;to identify their effect on biological characteristics and seed productivity of the crop. The research was conducted on soybean variety Millennium.
Pre-sowing experimental treatments of seeds were carried out with aqueous solutions of Epin-extra (0,025 g l), Agorostimulin (1 ml/l), Rival (1 ml/l) and Kornevin (0,5 g/l), and control – with water. During the study laboratory germination and energy of germination of seeds, and also morphometric indicators of seedlings and roots were defined. It was found that the pre-sowing treatment of soybean seeds of Millennium variety with stimulant drugs – Epin-extra (0,025 g/l), Agorostimulin (1 ml/l), Rival (1 ml/l) and Cornevin (0,5 g/l) increased seed productivity. In all variants of the experiment, both germination energy and seed germination were increased. It was found that the most effective drugs for the increase of germination energy and seed germination of Millennium soybeans are Epin-extra (0,025 g/l) and Agorostimulin (1 ml/l).
Under the action of plant growth stimulators, morphometric changes occurred in soybean seedlings. The drugs affected the length of the hypocotyls in seedlings of soybean culture. Under the use of Epin-extra (0,025 g/l) the length of hypocotyls increased by 18 %, under the action of Agorostimulin (1 ml/l) – by 32 %, under Cornevin (0,5 g/l) treatment - by 41 % and after the use of the drug Rival (1 ml/l) – by 85 %. Stimulators helped to lengthen the main root of soybean seedlings. The largest indicator of the length of the main root was found under the treatment of such drugs Riaval and Agorostimulin. It was found that all studied drugs contributed to the regrowth of lateral roots in soybean seedlings, but the best effect was observed under the usage of the drug Cornevin (0,5 g/l).
The significant increase in the dry weight of Millennium soybean seedlings was revealed with the use of stimulating plant growth regulators. The increase of the dry weight of soybean seedlings was detected under the pre-sowing treatment of seeds with Cornevin (by 36 %), Agrostimulin (by 50 %), and Rival (by 88 %) in comparison to the control.
Pre-sowing treatment of soybean seeds leads to the increase of dry weight of roots. The best effect on the increase of dry weight of roots was found under the use of drugs Cornevin and Agrostimulin. The use of Epin-extra and Rival also led to a positive result, but not as significant as after the use of two previous drugs that were given above.

Published: January 2022

The advance of information technology and the availability of data in education management provide an opportunity, to run data analysis to assist top management in decision making. Information technology can transform data analysis in a more concise format, accurate, and in a short time, by using any available office application software which is already installed on the computer. However, even though the management at an operational-level in an organization usually already has the software installed on a computer to support the managing of data, the extent of knowledge and skills to use the software efficiently in decision making is still limited. This study applies the Trialogical Model to implement decision support tools for data analysis of distribution lecturer’s teaching and learning (TnL) hour at IPG Kampus Pendidikan Teknik (IPGKPT) by grade specifications. A literature review using the interpretive paradigm involved the Trialogical Model (includes Monological and Dialogical), which is a knowledge-based model was carried out to run the data analysis using a Microsoft (Ms) Excel spreadsheet with Visual Basic for Application (VBA) and graphical interface. The findings show the usability of the Trialogical Model in the development of the decision support tool for TnL data analysis.

Cancer pain is underdiagnosed, and it is the responsibility of the primary care physician and specialist to treat and give these patients the appropriate medication. The patient hurts what the patient says hurts. This concept that seems obvious, is an everyday reality and this article aims to introduce doctors to the management of this exciting and not always well managed problem [1-3].
Endocrine Toxicities Of Checkpoint Inhibitor Immunotherapy:diagnostic Challenge And Management
Authors: Stevens Alys
Published: January 2022

Immune Checkpoint Inhibitors (ICIs) have transformed the landscape of oncology and are now utilized across many tumor sites. A significant proportion of patients receiving ICIs will develop endocrine toxicity, the majority of which are irreversible and potentially fatal. Toxicities can affect more than one endocrine organ at a time, occur even following discontinuation of therapy, and often present with non-specific symptoms. A low threshold to consider these toxicities within the differential diagnosis is therefore of paramount importance. Once detected many of the hormone deficiencies associated with ICIs can be effectively replaced exogenously; following which most ICIs can be safely continued. This is of particular importance as there is emerging evidence to suggest that patients who develop toxicity may ultimately have overall improved outcomes from a cancer perspective in some tumor sites.

MODEL GERAKAN REKLAIMING TANAH DALAM PERSPEKTIF MASYARAKAT ADAT KASUS DI WILAYAH KABUPATEN KOTAWARINGIN TIMUR
Authors: Rusmanto Joni , Sonia Ulfaritha Ester
Published: January 2022

Tenure conflicts between indigenous communities and plantation companies are based on differences in the legality of claims. The community as a subsystem of traditional farmers underlies the claim of management rights based on traditional knowledge. On the other hand, plantation companies based the legality of claims based on agrarian law that is normative positivistic with a capitalistic economic orientation. In Henri Lefebvre's perspective, in fact there is no completely "ideal" space because space itself is spatially in modern capitalist society as an arena of battle that will never be completely contested. All interested parties will continue to try to find ways to dominate the use or utilization of a space and reproduce all knowledge to maintain their hegemony over the use of that space. In that context, social movements can be understood as community efforts in producing social space.

Authors: Gibbons Melinda , Taylor Anna Lora , Szepe Arden , Wheat Laura S.
Published: January 2022

Though research on service-learning is growing, little is known about how service-learning interventions can support and prepare peer mentors. This article discusses a bounded case study that examined the learning experiences of peer mentors working with students with intellectual and developmental disabilities (I/DD) through a formal service-learning course for undergraduate students. Current and former peer mentors, instructors, and the I/DD postsecondary education program director participated in semi-structured interviews that focused on mentors’ experience of peer mentoring. The case study showed that mentors gained valuable real-world experience and professional development as well as increased empathy and self-awareness. In addition, staff noted the transformative nature of the experience for peer mentors, including enhanced cognitive and emotional connections, decreased anxiety, and increased self-confidence. Staff intentionality regarding the design of the course and classroom experiences represented both prior planning and responsiveness to mentor needs throughout the service-learning experience. This case study illustrates the impact of service-learning for those working with a postsecondary education program for students with I/DD.
Measuring the Impact of Community Engagement: Development of the BACE Scale
Authors: Miller Lee , McCauley Joyce , Mehta Sanjay
Published: January 2022

While the benefits of community engagement have been discussed extensively in the academic literature, there exist few assessment tools that can measure these benefits accurately. Using descriptive research methodology, the authors developed a robust measure—the Benefits of Academic Community Engagement (BACE) scale—that assesses student perceptions of two specific benefits across multiple disciplines: personal development and social responsibility. Three studies to test and refine the new scale are discussed. In considering the limitations of the studies the authors point to opportunities for future research to determine the scale’s validity across disparate settings. Results show that the instrument effectively captures student perceptions of the benefits of community engagement.

Published: January 2022

In the first hour following delivery, the infant should be breastfed immediately, which is known as Early Initiation of Breastfeeding (IMD). Breastfeeding within the first hour of life may help to minimize infant deaths from pneumonia, diarrhea, and hypothermia, among other causes. At the Watampone Health Center, the goal of this research was to discover if there was a link between maternal knowledge and family support and the implementation of early beginning of breastfeeding for postpartum moms. Research methods employed in this study include quantitative research using a cross-sectional design and a questionnaire. The sampling strategy used was purposive sampling, and a total of 45 postpartum moms were included in the study. The investigation was carried out at the Watampone Health Center. Using a paired t test, the researchers discovered that there was no relationship between maternal knowledge and the implementation of early initiation of breastfeeding in postpartum mothers (P value = 0.527), but that there was a relationship between family support and the implementation of early initiation of breastfeeding in postpartum mothers (P =0.047). The let-down reaction is controlled by the emotional state or sentiments of the mother, and the smoothness of the let-down reflex is determined by the smoothness of the family. Improve services by giving counseling, particularly to parents and spouses, in order to provide guidance, as well as inspiration to women about the necessity of starting breastfeeding as soon as possible.

The effects of D-dimer high rates on prognosis and mortality in chronic obstructive respiratory disease
Authors: SAYMAZ Zeynep Tilbe , ÇELİK Deniz , YILDIZ Murat , ERTAN Özlem
Published: January 2022

Aim: We aim to answer the question of “Can D-dimer be an indicator of prognosis and mortality in COPD exacerbations?” by doing retrospective research on the prognosis and mortality of patients who had high D-dimer levels in COPD exacerbations with no thromboembolism detected.

Material and Method: Our research is retrospective and cross-sectional. A total of 115 patients who had applied to our hospital between January 2018 and January 2019 with COPD acute exacerbations and who had higher D-dimer levels detected than the 0.44 mg/L upper limit of our hospital’s laboratory are included in this research. All patients have been previously diagnosed with COPD by a pulmonologist and have been undergoing treatment. Patients under the age of 18, patients whose information was not accessible through their files, pregnant patients, patients who have not been diagnosed with COPD by a pulmonologist, patients who had been diagnosed with lung malignancy through pathology, patients where pulmonary embolism was detected through pulmonary CT angiography, patients with renal function test disorder and patients with known renal failure are not included in this study.

Results: A total of 115 patients were included in the study. Patients who developed mortality had statistically significant lower levels of OSAS, higher rates of pneumonia, anemia, and liver failure, higher numbers of applications to emergency services in 1 year, higher numbers of hospitalizations due to COPD acute exacerbations in 1 year, higher numbers of intensive care unit admissions due to COPD acute exacerbations in 1 year and lower survival time. In addition, patients who developed mortality had statistically significant lower rates of group B and C and higher rates of group D according to the classification of Global Initiative of Chronic Obstructive Lung Disease (GOLD). Although the D-dimer levels were higher in patients who developed mortality, there were no statistically significant differences between groups. No significant cut-off value for D-dimer was calculated.

Conclusion: As a result, although our study has found higher D-dimer levels in patients who develop mortality, these results were not statistically significant.

Authors: ARSLAN Kadem , BAŞ Süleyman
Published: January 2022

Aim: We aimed to determine the frequency of troponin elevations in COVID-19 patients and to investigate the role of troponin in demonstrating the prognosis of COVID-19 by examining the clinical course of theese patients.

Material and Method: Patients diagnosed with COVID-19 disease were included in the study. Patient files were analyzed retrospectively through the hospital information management system.Patients with high troponin levels were identified and comparisons were made with patients with normal troponin levels.

Results: 1468 patients were included in the study.Troponin level was found to be high in 6.7% of the patients.The presence of pneumonia on thorax CT rate,hospitalization rate,ICU admission rate,intubation rate was significantly higher in patients with high troponin levels.The mortality rate was 2.1% in the whole group.The mortality rate was significantly higher in the patients with high troponin levels.Total length of hospital and ICU stay were significantly higher in patients with high troponin levels.There was a significant positive correlation between the troponin levels of the patients at admission and the total length of hospital stay and length of ICU stay. 49.5% of COVID-19 patients had another comorbid disease.Hypertension was the most common comorbid disease. The rate of troponin elevation and troponin levels were significantly higher in patients with other comorbid diseases.

Conclusion: It has been found that high troponin levels in COVID-19 patients may be associated with a poor clinical prognosis. Troponin can be used as a predictor of prognosis with more comprehensive studies and long-term follw-up results in the future.
Observations with the Southern Connecticut Stellar Interferometer. I. Instrument Description and First Results
Authors: Horch Elliott P. , Weiss Samuel A. , Klaucke Paul M. , Pellegrino Richard A. , Rupert Justin D.
Published: January 2022

We discuss the design, construction, and operation of a new intensity interferometer, based on the campus of Southern Connecticut State University in New Haven, Connecticut. While this paper will focus on observations taken with an original two-telescope configuration, the current instrumentation consists of three portable 0.6 m Dobsonian telescopes with single-photon avalanche diode detectors located at the Newtonian focus of each telescope. Photons detected at each station are time stamped and read out with timing correlators that can give cross-correlations in timing to a precision of 48 ps. We detail our observations to date with the system, which has now been successfully used at our university in 16 nights of observing. Components of the instrument were also deployed on one occasion at Lowell Observatory, where the Perkins and Hall telescopes were made to function as an intensity interferometer. We characterize the performance of the instrument in detail. In total, the observations indicate the detection of a correlation peak at the level of 6.76σ when observing unresolved stars, and consistency with partial or no detection when observing at a baseline sufficient to resolve the star. Using these measurements, we conclude that the angular diameter of Arcturus is larger than 15 mas and that of Vega is between 0.8 and 17 mas. While the uncertainties are large at this point, both results are consistent with measures from amplitude-based long baseline optical interferometers.
The UV/Optical Peak and X-Ray Brightening in TDE Candidate AT 2019azh: A Case of Stream–Stream Collision and Delayed Accretion
Authors: Liu Xiao-Long , Dou Li-Ming , Chen Jin-Hong , Shen Rong-Feng
Published: January 2022

We present and analyze the optical/UV and X-ray observations of a nearby tidal disruption event (TDE) candidate, AT 2019azh, from ∼30 days before to ∼400 days after its early optical peak. The X-rays show a late brightening by a factor of ∼30–100 around 200 days after discovery, while the UV/opticals continuously decayed. The early X-rays show two flaring episodes of variation, temporally uncorrelated with the early UV/opticals. We found a clear sign of X-ray hardness evolution; i.e., the source is harder at early times and becomes softer as it brightens later. The drastically different temporal behaviors in X-rays and UV/opticals suggest that the two bands are physically distinct emission components and probably arise from different locations. These properties argue against the reprocessing of X-rays by any outflow as the origin of the UV/optical peak. The full data are best explained by a two-process scenario, in which the UV/optical peak is produced by the debris stream–stream collisions during the circularization phase; some shocked gas with low angular momentum forms an early, low-mass “precursor” accretion disk that emits the early X-rays. The major body of the disk is formed after the circularization finishes, whose enhanced accretion rate produces the late X-ray brightening. Event AT 2019azh is a strong case of a TDE whose emission signatures of stream–stream collision and delayed accretion are both identified.

Considering the positions, orientations, and polarization fractions of the double radio relics measured by the LOFAR study, we suggest that A1240 is a postmerger binary system in the returning phase with a time since collision of ∼1.7 Gyr. With the SDSS DR16 data analysis, we also find that A1240 is embedded in the much larger scale (∼80 Mpc) filamentary structure whose orientation is in remarkable agreement with the hypothesized merger axis of A1240.
Gas Dynamics in the Galaxy: Total Mass Distribution and the Bar Pattern Speed
Authors: Li Zhi , Shen Juntai , Gerhard Ortwin , Clarke Jonathan P.
Published: January 2022

Gas morphology and kinematics in the Milky Way contain key information for understanding the formation and evolution of our Galaxy. We present hydrodynamical simulations based on realistic barred Milky Way potentials constrained by recent observations. Our model can reproduce most features in the observed longitude–velocity diagram, including the Central Molecular Zone, the Near and Far 3 kpc arms, the Molecular Ring, and the spiral arm tangents. It can also explain the noncircular motions of masers from the recent BeSSeL2 survey. The central gas kinematics are consistent with a mass of 6.9 × 108
M
⊙ in the Nuclear Stellar Disk. Our model predicts the formation of an elliptical gaseous ring surrounding the bar, which is composed of the 3 kpc arms, the Norma arm, and the bar-spiral interfaces. This ring is similar to those “inner” rings in some Milky Way analogs with a boxy/peanut-shaped bulge (e.g., NGC 4565 and NGC 5746). The kinematics of gas near the solar neighborhood are governed by the Local arm. The bar pattern speed constrained by our gas model is 37.5–40 km s−1 kpc−1, corresponding to a corotation radius of R
CR = 6.0–6.4 kpc. The rotation curve of our model rises gently within the central ∼ 5 kpc, significantly less steep than those predicted by some recent zoom-in cosmological simulations.
Measuring the α-abundance of Subsolar-metallicity Stars in the Milky Way’s Central Half-parsec: Testing Globular Cluster and Dwarf Galaxy Infall Scenarios

Published: January 2022

While the Milky Way nuclear star cluster (MW NSC) has been studied extensively, how it formed is uncertain. Studies have shown it contains a solar and supersolar metallicity population that may have formed in situ, along with a subsolar-metallicity population that may have formed via mergers of globular clusters and dwarf galaxies. Stellar abundance measurements are critical to differentiate between formation scenarios. We present new measurements of [M/H] and α-element abundances [α/Fe] of two subsolar-metallicity stars in the Galactic center. These observations were taken with the adaptive-optics-assisted high-resolution (R = 24,000) spectrograph NIRSPEC in the K band (1.8–2.6 micron). These are the first α-element abundance measurements of subsolar-metallicity stars in the MW NSC. We measure [M/H] = − 0.59 ± 0.11, [α/Fe] = 0.05 ± 0.15 and [M/H] = − 0.81 ± 0.12, [α/Fe] = 0.15 ± 0.16 for the two stars at the Galactic center; the uncertainties are dominated by systematic uncertainties in the spectral templates. The stars have an [α/Fe] in between the [α/Fe] of globular clusters and dwarf galaxies at similar [M/H] values. Their abundances are very different than the bulk of the stars in the nuclear star cluster. These results indicate that the subsolar-metallicity population in the MW NSC likely originated from infalling dwarf galaxies or globular clusters and are unlikely to have formed in situ.

Published: January 2022

An integral part of the issue of terrorism is not only the consequences of committed terrorist acts that lead to subsequent security measures, but also the causes of terrorist activities, which determine the reasons why people are motivated to commit them. This paper focuses on the social, economic, and security policy factors that potentially generate future terrorist activities. The main goal is to analyse the opinions of 52 respondents from 31 countries, i.e., experts from military, police, and academic institutions. The method of analytical hierarchy was chosen for the respondents, who decided on the importance of individual factors. According to the respondents, the most important factor of the current national and violent international war is the security-political area. It is followed by social inequality (in the social area) and unemployment (in the economic area). The achieved results show a certain reflection of the evaluated factors regarding the competitiveness of individual countries, which can significantly affect not only the level of threat of terrorist activities in the country, but also their potential mobility.

Trans-Formational Qualities of the Dys-&-Functional – The interplay of the questioning Senses of Real, the quest for a Sense of the Possible and enacting a Sense of the Doable – Non-linear perspectives on spiraling moves
Authors: Kuepers Wendelin
Published: January 2022

Cet article met en avant des dimensions et qualités critiques, imaginatives et utopiques, ainsi que pragmatiques, dans l’art et l’esthétique ayant une valeur transformatrice pour les études et la pratique organisationnelles et du leadership. Le potentiel de transformation des processus artistiques et esthétiques fait référence à leur capacité à remettre en question le « sens du réel » et à produire un « sens du possible » –tel que décrit par Musil dans son livre « L’homme sans qualités » – complété par un « sens du faisable ». Ceci est faisable grâce à leur capacité critique à remettre en question les sens fermés du « réel » et à offrir des perspectives imaginatives (utopiques) sur ce qui est ou pourrait être possible. En ce sens, les qualités créatives de l’art et de l’esthétique peuvent avoir une fonction critique et libératrice. Celles-ci peuvent être complétées différemment par un sens plus pragmatique de ce qui peut être fait concrètement, et toutes ces fonctions ensemble provoquent des qualités transformationnelles qui sont très pertinentes pour les réalités et les pratiques du leadership et des organisations. Sur la base de ces sens et en relation avec l’art et l’esthétique, la linéarité et les lignes linéaires sont problématisées et le rôle des lignes et des cycles tordus et chasmiques est souligné. Enfin, certaines implications et perspectives sont discutées en conclusion.
L’Église dans le temps de ce monde : imagination, corporéité, altérité
Authors: Brison Sylvain
Published: January 2022

Parce que l’Église vit en solidarité avec le monde les transformations nécessaires vers le Royaume de Dieu, les crises qui l’affectent questionnent sa nature et révèlent les défis de l’ecclésiologie. L’article tente de dégager les perspectives de penser pour renouveler le discours sur l’Église. La première partie réfléchit la dimension temporelle de la réflexion ecclésiologique afin de déplacer le centre de gravité de la nature de l’Église vers sa finalité. Elle explore également les enjeux de la narrativité pour l’ecclésiologie. La seconde partie examine la relation de l’Église au monde pour proposer une « ecclésiologie politique ». Enfin, l’article ouvre sur les enjeux du « vivre ensemble » l’unité dans la diversité en orientant la réflexion à partir des ressources de l’imagination théologique.
L’impératif de l’adaptation : la soumission du droit, de l’économie et du management aux catégories de la biologie moderne
Authors: Rappin Baptiste
Published: January 2022

Ainsi que l’indique explicitement le titre de cet article, nous nous proposons d’observer et d’analyser la présence grandissante sinon l’omniprésence des catégories de la biologie dans les sciences juridiques, économiques et de gestion. Nous partirons tout d’abord de trois coups de sonde, un par discipline (le régime nazi pour le droit, le néolibéralisme pour l’économie, la mode de la résilience pour la gestion), pour donner quelque crédit à notre hypothèse. Puis nous mettrons en exergue l’hégémonie de la biologie et de ses concepts dès les débuts de la société industrielle avant de pointer ses évolutions dans la cybernétique dont les effets ne cessent de se faire ressentir aujourd’hui. Pour conclure, nous défendrons la thèse que la managérialisation du monde en cours annonce une régression animale au détriment de toutes les constructions symboliques de l’humanité, au premier rang desquelles la cité politique et ses institutions.
Géographicité de l’être et accaparement des terres agricoles : une problématique de la consubstantialité de la géographie et de l’ontologie
Authors: Sofack Noël
Published: January 2022

L’accaparement des terres qui est au cœur de l’actualité depuis quelque temps pose fondamentalement un problème anthropologique, philosophique, métaphysique et ontologique. C’est du moins la lecture que l’on peut en faire à partir d’une herméneutique de la pensée d’Augustin Berque et de l’anthropo-cosmologie africaine. En effet, « l’ être de l ’humain est géographique », c’est-à-dire que l’on ne peut pas le penser sans prendre en compte prioritairement sa géographicité. Le propos de cet article consiste à montrer que l’accaparement des terres, qui implique de facto des déplacements forcés des populations autochtones de leur Terre-Mère, conduit à une sorte de dys-localisation, c’est-à-dire à une rupture du lien consubstantiel entre géographie et ontologie, mettant ainsi en cause la géographicité de l’être.
Être maître selon Ortega y Gasset
Authors: Bonilla Javier Zamora
Published: January 2022

Le philosophe espagnol José Ortega y Gasset a écrit de nombreux textes à propos de la pédagogie, qui dès sa jeunesse fut une préoccupation majeure. Nous analysons ici ses idées pédagogiques à partir de concepts tels que « pédagogie du paysage », « pédagogie de l’allusion », « pédagogie de la contamination », « vocation » et « mission ». L’influence de la philosophie krausiste de Francisco Giner de los Ríos sur la pensée ortéguienne a été notable, comme nous pourrons le voir. Ils entretinrent une relation étroite et, surtout, ils désiraient avec la même ardeur moderniser la société espagnole. Ortega y Gasset transposa ses idées pédagogiques à sa propre expérience de professeur d’université. Beaucoup de ses disciples en ont témoigné, comme nous le rapportons ici.
Post inhibitory rebound spike related to nearly vertical nullcline for small homoclinic and saddle-node bifurcations
Authors: Wang Xianjun , Gu Huaguang
Published: January 2022

A spike induced by inhibitory stimulation instead of excitatory stimulation, called post-inhibitory rebound (PIR) spike, has been found in multiple neurons with important physiological functions, which presents counterintuitive behavior mainly related to focus near Hopf bifurcation. In the present paper, the condition for the PIR spike is extended to small homoclinic orbit (SHom) and saddle-node (SN) bifurcations, and the underlying mechanism is acquired in a neuron model. Firstly, PIR spike is evoked from a stable node near the SHom or SN bifurcation by a strong inhibitory stimulation. Then, the dynamics of threshold curve for a spike, vector fields, and nullcline of recovery variable are used to well explain the cause for the PIR spike. The shape of threshold curve for the node resembles that of focus. The nullcline plays an important role in forming PIR spike, which is analytically identified at last. Besides, a sufficient condition is acquired from the integration to a differential equation, and the range of parameters for the PIR spike is presented. The extended bifurcation types and the underlying mechanisms for the PIR spike such as the nullcline present comprehensive and deep understandings for the PIR spike, which also provides potential strategy to modulate the PIR phenomenon and even related physiological functions of neurons.

Rumen methanogens prevent the accumulation of fermentation gases in the rumen and generate methane that increases global warming and represents a loss in animals' gross energy. Non-traditional feed resources such as the by-products of date palm (Phoenix dactylifera) and olive (Olea europaea) trees have received attention to be used in animal feeding. This study evaluated the impact of non-traditional feed resources including olive cake (OC), discarded dates (DD), and date palm frond (DPF) in sheep diet on rumen fermentation, diversity and relative abundance of rumen methanogens. Nine adult rams were assigned to three equal groups and fed three diets: traditional concentrates mixture (S1); non-traditional concentrate mixture (S2) based on DD and OC; and (S3) composed of the same S2 concentrate supplemented with DPF as a roughage part. The results showed that rumen pH was higher with S3 diet than the other two diets. However, the S1 diet showed the highest values of total volatile fatty acids (TVFA) and rumen ammonia. In addition, the proportions of acetic and butyric acids were increased, whereas propionic acid declined in S2 and S3 compared to the S1 diet. Rumen methanogens were dominated by Methanobrevibacter that showed a numeric decline by including DD, OC, and DPF in the animal diets. Principal component analysis (PCA) based on rumen fermentation parameters and relative abundances of methanogens genera showed three distinct clusters. Also, positive and negative correlations were revealed between methanogens genera and rumen metabolites. This study expands the knowledge regarding the effect of agricultural byproducts on rumen fermentation and the methanogenic community.
