Financial security of the competitiveness of business subjects in the agro-food sphere
Authors: Guohe Qin
Published: October 2023

The aggravation of the global problem of hunger in the world significantly actualizes the task of guaranteeing national food security and expanding Ukraine's participation in the global agro-food chain. The inclusion of value in European and global agro-food chains is currently a priority with the strategic task of developing the agrarian sector, which requires increasing the competitiveness of domestic agricultural raw materials and their food processing products. It is necessary to outline the mission vision of long-term goals and objectives of sustainable development of the agricultural sector and search for effective mechanisms to ensure the achievement of the set goals and objectives of agricultural management to find strategic mechanisms for managing competitive agricultural production at the initial stage. The importance and priority of the agricultural sector for achieving global and national goals of sustainable development led to the realization of the need to find practical tools and mechanisms for strategic management of the competitiveness of agricultural production. Effective development of the agricultural sector and rural areas in the future is possible only based on sustainability and inclusiveness, which requires an integrated approach to management decision-making. The effectiveness of the strategic management of agriculture will be expressed in how quickly and adequately the management system will respond to new requirements, opportunities, challenges, and threats created by the competitive environment. Inclusive provision of business entities of the agro-food sector with financial resources becomes an essential condition for further developing its industries and solving the strategic task of increasing the level of competitiveness. The central core of the mechanism of inclusive provision of agriculture is the investment factor, which forms the prerequisite for the activation of innovative processes both in production and in the further development of rural areas.

Les modalités et enjeux de l’appropriation par les agences de l’eau du concept de solutions fondées sur la nature appliqué à la gestion de l’eau : le cas de l’agence de l’eau Rhône Méditerranée Corse
Authors: DRAPIER Ludovic , GUERIN Joanna , REY Freddy
Published: October 2023

Les solutions fondées sur la nature (SFN) correspondent à des actions permettant de relever des défis sociétaux tout en contribuant à la préservation de la biodiversité, en s’appuyant sur le fonctionnement des écosystèmes. Parmi les gains sociétaux, on peut citer la prévention des risques liés à l’eau et la préservation de la ressource en eau. En France, les agences de l’eau sont des acteurs centraux dans la mise en œuvre des politiques de l’eau. Le concept de SFN est apparu au cours des années 2010 et s’impose de plus en plus dans les stratégies et les orientations des agences, qui ont progressivement évolué au cours des dernières années vers une meilleure prise en compte des milieux aquatiques. L’objet de cet article est de comprendre comment une agence de l’eau, ici Rhône Méditerranée Corse (AERMC), s’approprie ce nouveau concept. Pour cela, nous nous appuyons sur une enquête qualitative reposant sur la réalisation d’entretiens semi-directifs menés avec des personnels de l’agence et un travail d’observation participante. Nous montrons tout d’abord la progressive intégration des SFN dans les productions de l’agence. Puis nous faisons le constat de deux modalités d’intégration différentes entre le grand et le petit cycle de l’eau. Pour la politique dédiée aux milieux aquatiques, les SFN s’inscrivent dans la continuité des actions menées par l’agence tandis qu’elles constituent une modalité de précision dans le champ des techniques alternatives pour la gestion des eaux pluviales. Ces éléments permettent de souligner quelques enjeux liés à l’appropriation des SFN pour l’AERMC et de manière plus générale au sein d’autres institutions de gestion de l’eau.

The Economic Development of Barbados
Authors: Mcgregor Howard Michael
Published: October 2023

In The Economic Development of Barbados, Michael Howard discusses mainly economic factors influencing Barbadian economic development since the Second World War. He provides an interpretation of the role of foreign investment and public policy in the development process, within the conceptual framework of institutional structural analysis. The primary focus of this book is Sir Arthur Lewis's model of industrialization, sometimes known as the Puerto Rican model, which determined the dependent path of the economy after 1960. Howard evaluates the economic consequences of this model with reference to the agricultural, manufacturing, tourism and external sectors of the economy. He also identifies some of the policy issues facing the government in the context of globalization. Howard concludes that although Barbados has achieved a commendable level of development, with the services sector as the main engine of growth, structural weaknesses remain in the manufacturing and agricultural sectors. This highly readable text is a valuable addition to the development literature. readers, including development economists, students and policy makers.

Authors: Tablatin Christine Lourrine S.
Published: October 2023

Academic institutions must be able to adapt to rapid technological advancements and bridge the continuous skill gap between industry expectations and student academic preparation. This study aimed to analyze and present an updated view of the essential IT competencies perceived by IT practitioners and highlight the skills gap between the perceptions of industry practitioners and the academic community. The study utilized quantitative and qualitative research to determine the most relevant competencies according to IT practitioners and academicians. The findings revealed that competencies in microprocessors, semiconductors, embedded systems, mobile and wireless computing, and robotics were perceived as somewhat important/important by IT practitioners. However, IT faculty members perceived these competencies as very important/important. These findings suggest that there is a gap between the acquired competencies in the university and the competencies needed by the industry. Further, the analysis of the competencies in the different IT jobs revealed the competencies perceived by the IT practitioners vary depending on the specific IT job. This research brings insights into the relevant competencies of the IT workforce and how to improve the IT curriculum to produce professionals who meet industry demands.

Quality control of endotoxin measurement in dust samples/Qualitätskontrolle der Endotoxinmessung in Staubproben
Authors: Liebers Verena , Düser Maria , Raulf Monika
Published: October 2023

Endotoxin activity determination is a common tool and a surrogate marker for bioaerosol assessment and is used at workplaces especially for this purpose. The reliability of the methods used for quantification in airborne dust samples is important for exposure estimation and thus for assessing the workplace situation. Within the scope of this study, the reproducibility of the endotoxin activity values determined with the two common methods, the LAL test and the rFC test, should be determined and compared. 21 water-based dust extracts from electrostatic dust collectors (EDC) were used for repeated endotoxin quantification using LAL and rFC test. As a result, twelve independent standard curves (0-50 EU/ml) were applied showing a median coefficient of variation (CV) of 9% for rFC and 12% for LAL test. The measured endotoxin activities of the samples could be reproduced within one test as well on three consecutive days. The CV of the 7- and 8-fold measured samples was below 20%. in 92% (LAL) and 93% (rFC) of the samples. Multiple measurements of the same sample showed that the results of LAL and rFC tests are highly reproducible. To eliminate interfering factors detected by recovery of spiked samples, dilutions of the samples are valuable methodological tools. This study demonstrates that quality-assured quantification of endotoxin activity is possible with both methods and is suitable for workplace measurements using the respective Standard Operation Procedure (SOP).

Authors: BAKİ ERİN Kübra , ÇEBİ Nazime
Published: October 2023

Aim: The objective of this research was to examine the impact of fasting on thiol-disulfide hemostasis in a population of healthy pregnant women.

Material and Methods: The study, conducted during Ramadan in 2021, included a control group of 53 pregnant women who were fasting and 57 pregnant women with similar demographics who were not fasting. The disulfide, native thiol, and total thiol concentrations in centrifuged blood plasma and venous blood plasma were all looked at. The ratios "disulphide/thiol 100," "disulphide/total thiol 100," and "thiol/total thiol 100" were all calculated.

Results: There were 32 pregnant women in the second trimester and 21 pregnant women in the third trimester among fasting participants, whereas there were 33 pregnant women in the second trimester and 24 pregnant women in the third trimester among non-fasting participants. Disulfide, disulfide/nativethiol*100, disulfide/totalthiol*100, and native/totalthiol*100 ratios were not significantly different between groups. A statistically significant difference was seen between the groups when comparing the mean values of native thiol and total thiol.

Conclusion: Our research is one of the first to examine homeostasis in pregnant women who were fasting, making it a remarkable advance in the field. The study demonstrated a discernible alteration in the thiol-disulfide balance, enhancing the process of oxidation. Fasting during pregnancy is associated with an increase in oxidative stress.

Published: October 2023

Background: Despite the protective effects of stromal cell-derived factor 1 (SDF-1) in stimulating muscle regeneration shown in experimental research, there is a lack of clinical studies linking circulating SDF-1 concentrations with muscle phenotypes. In order to elucidate the role of SDF-1 as a potential biomarker reflecting human muscle health, we investigated the association of plasma SDF-1 levels with sarcopenia in older adults.Methods: This cross-sectional study included 97 community-dwelling participants who underwent a comprehensive geriatric assessment at a tertiary hospital in South Korea. Sarcopenia was defined by specific cutoff values applicable to the Asian population, whereas plasma SDF-1 levels were determined using an enzyme immunoassay.Results: After accounting for sex, age, and body mass index, participants with sarcopenia and low muscle mass exhibited plasma SDF-1 levels that were 21.8% and 18.3% lower than those without these conditions, respectively (P=0.008 and P=0.009, respectively). Consistently, higher plasma SDF-1 levels exhibited a significant correlation with higher skeletal muscle mass index (SMI) and gait speed (both P=0.043), and the risk of sarcopenia and low muscle mass decreased by 58% and 55% per standard deviation increase in plasma SDF-1 levels, respectively (P=0.045 and P=0.030, respectively). Furthermore, participants in the highest SDF-1 tertile exhibited significantly higher SMI compared to those in the lowest tertile (P=0.012).Conclusion: These findings clinically corroborate earlier experimental discoveries highlighting the muscle anabolic effects of SDF- 1 and support the potential role of circulating SDF-1 as a biomarker reflecting human muscle health in older adults.
THE DIRECT AND INDIRECT EFFECTS OF INTERNAL ENABLERS ON INTERNAL INTEGRATION AND BUSINESS PERFORMANCE
Authors: Ruzo-Sanmartín Emilio , Abousamra Alaa A. , Otero-Neira Carmen , Svensson Göran
Published: October 2023

The present paper aims to assess both the direct as well as the indirect effects of internal enablers on internal integration and business performance in the supply chain. A full managerial comprehension of the connection between supply chain integration (SCI) and business performance is missing so far and earlier results are inconclusive. To fill this gap, this study expands the growing body of research on SCI and contributes to the SCM field by explaining the direct and indirect effects of internal enablers on internal integration and business performance. Results show that hierarchical organizational culture influences internal integration and supply chain performance, that top management support and information technology department size influence internal integration, and, finally, that supply chain performance impacts operational performance. These findings confirm the relevance for firms to pay attention to those key internal enablers of internal integration, and their benefits on business performance. Considering our results, future research should deepen on the influence of internal integration on business performance by focusing on the links between internal integration and the other dimensions of SCI, that is supplier and customer integration, as well as with the external side of the supply chain performance.
Generalized Harris Sheet Equilibrium in Regularized Kappa Distributed Plasmas
Authors: Hau L.-N. , Chang C.-K. , Lazar M.
Published: October 2023

Harris sheet models with antiparallel magnetic field are the equilibrium solutions to the steady Vlasov–Maxwell equations, which have been widely adopted for the study of plasma instabilities and magnetic reconnection in thin current sheets. The original Harris equilibrium model assumes the Maxwellian velocity distribution, which necessarily gives rise to the isothermal current sheets. Many observations have shown that the suprathermal populations are indispensable features of particle distribution profiles, which may well be fitted by the Kappa distribution (KD) functions with the free parameter κ. The Harris equilibrium based on the standard Kappa distribution (SKD), however, may become unphysical for

κ
≤

3

2

. Alternatively, the regularized KD (RKD) with two adjustable parameters, κ and α
2, has been proposed to replace the SKD in various studies. The RKD may recover the SKD for α
2 = 0, and Maxwellian model for α
2 = 0 and κ → ∞ . This paper presents the first results of adopting the nonthermal RKDs in the Harris equilibrium models. It is shown that the new RKD–Harris equilibrium is applicable for all κ values, and exhibits a stronger magnetic field associated with higher temperature in the asymptotic region. The proposed formulations for the generalized Harris sheet equilibrium may be applied to multiple component plasmas (e.g., electrons, protons) with different RKDs and temperatures.

We present the 2020 version of the Siena Galaxy Atlas (SGA-2020), a multiwavelength optical and infrared imaging atlas of 383,620 nearby galaxies. The SGA-2020 uses optical grz imaging over ≈20,000 deg2 from the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys Data Release 9 and infrared imaging in four bands (spanning 3.4–22 μm) from the 6 year unWISE coadds; it is more than 95% complete for galaxies larger than R(26) ≈ 25″ and r < 18 measured at the 26 mag arcsec−2 isophote in the r band. The atlas delivers precise coordinates, multiwavelength mosaics, azimuthally averaged optical surface-brightness profiles, model images and photometry, and additional ancillary metadata for the full sample. Coupled with existing and forthcoming optical spectroscopy from the DESI, the SGA-2020 will facilitate new detailed studies of the star formation and mass assembly histories of nearby galaxies; enable precise measurements of the local velocity field via the Tully–Fisher and fundamental plane relations; serve as a reference sample of lasting legacy value for time-domain and multimessenger astronomical events; and more.
Extreme Tidal Stripping May Explain the Overmassive Black Hole in Leo I: A Proof of Concept
Authors: Pacucci Fabio , Ni Yueying , Loeb Abraham
Published: October 2023

A recent study found dynamical evidence of a supermassive black hole of ∼3 × 106
M
⊙ at the center of Leo I, the most distant dwarf spheroidal galaxy of the Milky Way. This black hole, comparable in mass to the Milky Way’s Sgr A*, places the system >2 orders of magnitude above the standard M
•–M
⋆ relation. We investigate the possibility, from a dynamical standpoint, that Leo I’s stellar system was originally much more massive and, thus, closer to the relation. Extreme tidal disruption from one or two close passages within the Milky Way’s virial radius could have removed most of its stellar mass. A simple analytical model suggests that the progenitor of Leo I could have experienced a mass loss in the range 32%–57% from a single pericenter passage, depending on the stellar velocity dispersion estimate. This mass-loss percentage increases to the range 66%–78% if the pericenter occurs at the minimum distance allowed by current orbital reconstructions. Detailed N-body simulations show that the mass loss could reach ∼90% with up to two passages, again with pericenter distances compatible with the minimum value allowed by Gaia data. Despite very significant uncertainties in the properties of Leo I, we reproduce its current position and velocity dispersion, as well as the final stellar mass enclosed in 1 kpc (∼5 × 106
M
⊙) within a factor <2. The most recent tidal stream is directed along our line of sight toward Leo I, making it difficult to detect. Evidence from this extreme tidal disruption event could be present in current Gaia data in the form of extended tidal streams.

The sticking properties of dust in early phases of planet formation depend on the thermal history and ambient atmosphere. Therefore, dust will change its ability to build larger aggregates in collisions, depending on its location in protoplanetary disks. We aim at quantifying the change in sticking properties as chondritic dust is heated under various atmospheric conditions. In laboratory experiments, we milled two different meteorites (Sayh al Uhaymir 001 and Allende) to dust and formed millimeter-size cylinders. These cylindrical aggregates were sequentially heated from 600 to 1400 K in vacuum and in a hydrogen atmosphere, with compositional changes being tracked via Mössbauer spectroscopy. Using a Brazilian splitting test, the splitting tensile strength was determined. At higher temperatures, iron in silicates is reduced to metallic Fe(Ni) within the hydrogen atmosphere. In any case, adhesive forces are strongly increased by orders of magnitude from 1000 to 1400 K with minimum variations, depending on the atmospheric conditions. The dust in protoplanetary disks becomes ever more sticky, approaching a sublimation line upon exposure to temperatures of about 1400 K.
Characterizing biofilms and their associated biosignatures in an Arctic hypersaline cold spring Mars analog

Published: October 2023

The last surface-level aqueous environments on Mars were likely sulfurous brines that formed as the climate cooled and large bodies of water receded during the transition from the wet Noachian to the dry Hesperian (4.1 – 3.0 Gya). To understand the diversity of microorganisms that could have inhabited such environments and their associated biosignatures, we turn to analogous environments on Earth. Here we investigated biofilm communities and their associated biosignatures at Gypsum Hill, (GH), a perennial cold spring system located at nearly 80°N on Axel Heiberg Island in the Canadian high Arctic. The biofilms develop during the summer months alongside the oligotrophic and sulphur rich GH brines and spread out along the flood plains formed by meltwater and spring run-off. Our objective was to link the microbial community structure of the biofilms to geochemical changes across the GH site as an analog to the micro-niches that could have formed during the recession of an ancient Martian Ocean. We collected 14 morphologically distinct biofilms over two field season and found that minor variations in chemistry between proximal sites impacted community structure. 16S amplicon sequencing revealed that biofilms closest to outflow channels were dominated by sulfur oxidizing bacteria, suggesting that primary production may be driven by chemolithoautotrophy. The community structure shifted towards more heterotrophic and phototrophic populations the further the biofilms appeared from a spring source. Microbial eukaryotes at the GH site were investigated for the first time through 18S sequencing with diatoms and photoautotrophic algae dominating all biofilms. Lastly, we linked the biofilm communities to potential biosignatures by examining lipid profiles to help guide the search and identification of potential remnants of hypothetical ancient Martian life.

Published: October 2023

Crop yield in sub-Saharan Africa is often limited by low phosphorus fertility. Farmers in the region can apply phosphate rock, which should increase the plant-available phosphorus level, but this may be prone to sorption in acid soils of the Sahel. The objective of this study was to determine phosphorus (P) sorption characteristics of four representative soil series in Sahelian Mali namely, Longorola (Gleysol), Danga (Fluvisol), Niessoumana (Arenosol) and Konobougou (Acrisol) under Tilemsi Phosphate Rock (TPR) treatment. Data for phosphorus sorption was obtained by equilibrating 5 g of soils for 7 days at room temperature in 50 ml of 0.01M CaCl2 containing six (6) rates of phosphate as TPR (0, 10, 20, 40, 80,160 mg/L). The linear form of the Langmuir equation was used to calculate sorption parameters of the soils. The Gleysol with the greatest clay content had the highest phosphorus sorption maximum which was over three times greater than that of the Acrisol with the least clay content. The sorption maxima in the range of 59–200 mg/kg were well estimated with Langmuir sorption isotherm (R2 ≥ 0.78). Soil organic matter and clay contents influenced phosphorus sorption from the TPR. The degree of phosphorus saturation ranged from 2.39 to 6.47 %, being greater in the Arenosol. In a two-season field experiment on the Haplic Acrisol, we tested on maize, the TPR in two forms (powder and pellet) in addition to water-soluble diammonium phosphate at different rates (0, 11 and 16 kg P /ha). The water-soluble DAP and TPR (powder) had similar effects (p < 0.05) on soil P availability but with DAP producing greater grain yields. This shows that application of TPR in powder form can improve phosphorus availability as water-soluble DAP with positive impact on grain yield. The study provides useful information on P sorption characteristics of TPR amendment in the Sahel.
The optimal probability of the risk for finite horizon partially observable Markov decision processes
Authors: Wen Xian , Huo Haifeng , Cui Jinhua
Published: October 2023

This paper investigates the optimality of the risk probability for finite horizon partially observable discrete-time Markov decision processes (POMDPs). The probability of the risk is optimized based on the criterion of total rewards not exceeding the preset goal value, which is different from the optimal problem of expected rewards. Based on the Bayes operator and the filter equations, the optimization problem of risk probability can be equivalently reformulated as filtered Markov decision processes. As an advantage of developing the value iteration technique, the optimality equation satisfied by the value function is established and the existence of the risk probability optimal policy is proven. Finally, an example is given to illustrate the effectiveness of using the value iteration algorithm to compute the value function and optimal policy.
Le culte des faucons sacrés dans la IXe province de Haute Égypte : pratiques rituelles et échanges cultu(r)els
Authors: Claude Marion
Published: October 2023

Cet article propose, à travers l’étude, la publication et la recontextualisation d’un ensemble d’objets liés au culte des faucons sacrés dans la IXe province de Haute Égypte, d’examiner les modalités du culte aux animaux sacrés d’Haroéris seigneur de Létopolis dans cette province méridionale, à l’époque romaine. La comparaison des sources permet de dresser un panorama des pratiques rituelles encadrant le culte des faucons sacrés de la région tout en les replaçant dans le contexte plus large des cultes des animaux sacrés en Égypte, tant dans leurs similitudes que dans leurs différences. Enfin, les liens entre cultures égyptienne et hellénistique dans la région seront envisagés à l’aune des relations entre Haroéris et Asclépios.
Les légendes fonctionnelles de porte des temples ptolémaïques : élaboration et circulation d’un corpus original de textes
Authors: Leroux Nicolas
Published: October 2023

À l’époque ptolémaïque, un genre inscriptionnel s’est développé dans les temples : les légendes fonctionnelles de porte. Ces inscriptions se distinguent des « noms de portes » en ceci qu’elles indiquent la fonction principale des portes qui les contiennent. Cet article propose un catalogue aussi exhaustif que possible de toutes ces inscriptions et en livre une première analyse. Il s’agit notamment de comprendre comment ce type d’inscriptions a circulé d’un temple à l’autre, et d’en dégager des spécificités locales. Nous montrons également qu’avec d’autres corpus propres à cette période, les légendes de porte sont révélatrices de la place nouvelle que la décoration pariétale accorde désormais au prêtre officiant dans le temple.
Remarques préliminaires pour une étude synoptique des manuels de géographie liturgique à Edfou et à Dendara
Authors: Medini Lorenzo
Published: October 2023

Cette étude s’intéresse à l’analyse de quatre
corpus de scènes d’offrandes réparties entre les temples d’Edfou et de
Dendara. Ces scènes sont connues dans la littérature égyptologique
sous le nom « d’offrandes spécifiques », en raison des références aux
traditions mythologiques régionales qui apparaissent dans ces textes.
Chaque province est en effet représentée à travers un rite en relation
avec sa divinité principale. Bien que ces ensembles soient connus
depuis longtemps, une étude synoptique de ces textes fait encore
défaut. Seront ici présentés les premiers résultats de notre enquête
sur ce corpus, en nous concentrant plus particulièrement sur la
question de la structure de ces ensembles et de la transmission
textuelle de ces scènes.
L’influence séthienne sur les connexions entre l’oasis de Bahariya et la Vallée du Nil pendant la période gréco-romaine
Authors: Eller Audrey
Published: October 2023

Les oasis sont mentionnées avec parcimonie dans les processions géographiques canoniques des temples tardifs et, bien qu'elles ne constituent pas dans ce contexte des unités territoriales indépendantes, elles apparaissent liées à des provinces de la Vallée du Nil auxquelles elles fournissent des offrandes spécifiques. Bahariya est ainsi en connexion avec la xixe province de Haute Égypte. La relation entre ces deux régions est consolidée par l'adoration commune du dieu Seth et par une voie de circulation qui les relie. Ces liens religieux, vraisemblablement renforcés par la réalité géographique, sont mis ici en évidence et permettent de retrouver l’empreinte de Seth à une époque où sa démonisation rend les traces de son culte des plus ténues.
