Authors: NGETICH WYCKLIFF , K. Gitau Goerge , O. Abuom Tequiero , O. Aboge Gabriel
Published: September 2023

Cattle farming is an integral part of the livelihoods of farmers in Narok County. However, very few studies have been conducted to describe livestock production in different agroecosystems in Kenya. The objective of this study was to determine cattle production systems and characteristics under different agro-ecosystems. The study was conducted through the administration of semi-structured questionnaires to 817 farmers in three sublocations from Narok south sub-county.  The main livestock production systems were pure pastoral, communal grazing and zero-grazing where indigenous cattle were the predominant breed kept (86.8%) with a few farmers keeping crossbreeds or exotic breeds. However, sheep (75.1%) goats (79.4%), chicken (68.6%) and donkeys (32.9%) were also kept. The mean lactation period for cattle was 9.5 months with average inter-calving interval of 14.1 months.  More households (45.1%) grazed cattle within their own pastureland compared to pure pastoralism (12.5%), communal grazing (8.0%), zero grazing (0.9%), or combination (33.5%). Approximately 37.1% of the respondents herded their cattle, 13.1% were on free grazing, 36.6% both free grazing and herding whereas 13.2% used paddocks. The mean land area under pasture was estimated at 53.9 acres. The main source of drinking water was within the grazing field (63.6%) with 36.4% having had to take livestock elsewhere. Most households (85.7%) practicing mixed farming could easily access veterinary services compared to 57.2% and 55.1% in agro-pastoral and pure pastoral system respectively (p<0.0001). The main veterinary interventions were deworming, vaccination, and antibiotic administration. Most households (98.6%) had sprayed their livestock with 98.9% sourcing the products from agrovet outlets. More respondents (63.8%) in agro-pastoral compared to 61.5% and 49.7% from pastoral and mixed farming respectively were aware of East Coast Fever disease (p<0.0001). Cattle were principally fed on natural pasture either produced from owned or leased lands with farmers getting unequal access to veterinary services.

Published: September 2023

Due to the lack of new antimicrobial drug discovery in recent years and an ever-growing prevalence of multidrug-resistant “superbugs”, there is a pressing need to explore alternative ways to combat pathogenic bacterial and fungal infections. Building upon our previous work in the field of medicinal phytochemistry, the present study is focused on designing, synthesizing, and testing the altered bioactivity of new variants of two original bioactive molecules found in the Argemone mexicana plant. Herein, we report upon 14 variants of berberine and four variants of chelerythrine that have been screened against a pool of 12 microorganisms (five Gram-positive and four Gram-negative bacteria, and three fungi). Additionally, the crystal structures of two berberine variants are described. Several berberine variants show enhanced antibacterial activity compared to the unaltered plant-derived molecule. We also report promising preliminary tumor cytotoxicity effects for a number of the berberine derivatives.
Understanding Corruption and Social Norms: A Case Study in Natural Resource Management
Authors: Nash Richard , Scharbatke-Church Cheyanne , Toribio Zita , Woodrow Peter , Brinkerhoff Derick W.
Published: September 2023

Corruption undermines many outcomes across development sectors, yet little is known about how social norms drive corruption or undermine anticorruption efforts in sector work. The conservation sector is no exception. The current study examined corruption and social norms related to infrastructure investments and site planning decisions and their subsequent effect on conservation outcomes. The study focused on the Puerto Princesa Subterranean River National Park, one of four protected areas under the United States Agency for International Development (USAID) Sustainable Interventions for Biodiversity, Oceans and Landscapes (SIBOL) project in the Philippines, implemented by RTI International. Based on a site visit, key informant interviews, and extensive document analysis, our findings elucidate a unique governance structure that enabled project partners to navigate the significant corruption risks present. Direct social norms were not found to be driving corrupt decision making. However, indirect norms played a role by dictating inaction or silence—powerful behaviors—in the face of abuse of entrusted power for personal gain. Our analysis highlights the challenges and importance of having practitioners clearly define and understand what they mean by “corruption” as well as the importance of undertaking a systems analysis that incorporates the influence of social norms on behaviors within that system.
Competition between Feminatives and Masculinisms in Polish and Bulgarian Dictionaries
Authors: Eftimova Andreana
Published: September 2023

The article presents a study of the ways of presentation of one hundred names for professions, positions, ranks, etc. in the nomenclature list for professions in the Republic of Bulgaria, and then in the Dictionary of the Bulgarian Language (DBL) and The Great Dictionary of the Polish Language (Wielki słownik języka polskiego - WSJP), which strongly influence the editors' preferences and choice of masculinisms or feminisms in traditional and web-based media and encyclopedic products. The comparison between the Polish and Bulgarian dictionaries is carried out according to four criteria in order to establish the degree of asymmetry in the presentation of feminine and masculine forms.
On Politically-Driven Language Discrimination in Post-Soviet Space (from the Example of Occupied Abkhazia)
Authors: Gumbaridze Zhuzhuna , Gvarishvili Zeinab
Published: September 2023

The aim of this paper is to reflect the policy of the government of Georgia towards creating higher education opportunities for the youth residing in Abkhazia and outline the supporting measures taken by the Georgian side that contribute to Abkhazian youth’s integration into the mainstream of academia locally and worldwide. Accordingly, as the background of the issue, we start with a brief description of the language ideology in the occupied area and then move to a discussion of the factors which demonstrate the opportunities that ensure and simplify access to higher quality education in Georgia as well as abroad for the targeted group. There are two substantive issues: first, Russian language ideology imposition on Abkhaz youth and, second, the benefits of acquiring a degree in Georgia. We argue that the collapse of the Soviet Union and Georgia’s recent pro-Western politics have paved the road to new possibilities for cultivating a linguistically diverse, multiethnic, and tolerant society throughout Georgia. Young people living in both the occupied region and Georgia represent the generation that should cohabitate and find a common path of understanding and peace in order to build a common better future.

The review un-derlines the main aspects discussed in the book, pointing out the theoretical ap-proaches used by Lucian Boia in dealing with these topics not only in the reviewed book, but also in his other books related to these topics such as The Weather in the Imagination or Probleme de geografie istorica (Problematics of Historical Geography).
Fashion and Style. Bulgarian Modernism - in the 20s and 30s of the 20th Century
Authors: Azmanova-Rudarska Elena
Published: September 2023

The article examines the main literary, philosophical and cultural settings in N. Stoyanova's monographic study "Decorations and grimaces". N. Stoyanova studies Bulgarian literary modernism both through the topic of fashion and through its symbolism. It is at the point of contact between fact and fiction, between literature and its border fields - art, cultural studies, history, psychology, philosophy - that the unique essence of Stoyanova's literary analysis of fashion and its mechanisms of interpretation is revealed. Works by C. Mutafov, K. Konstantinov, N. Rainov and others are analyzed.
Miners - a Privileged Category of the Working Class? Valea Jiului (Romania) in Socialism and Post-Socialism
Authors: Mateoniu-Micu Maria
Published: September 2023

This article addresses the dynamics of social inequalities in socialist and post-socialist Romania, following the particular situation of Valea Jiului miners (in Romania), from the creating the image of the working-class heroes to the loss of preferential status, together with the post-1989 transition from communism to capitalism and from the planned economy to the market one. Therefore, the article includes the way in which the miners’ class identity was built over time, highlighting rather a preferential status of a psychological nature than a material one, the practices of disciplining their masculinity with the help of state propaganda and how this image of a homogeneous, disciplined and solidary group was diluted after the fall of communism.
The Rivalry between Italy and Great Britain to Obtain a Monopolistic Concession on the Albanian Oil
Authors: Verli Jorina , DUGOLLI Bujar
Published: September 2023

After his return to power in 1924, the problems of the weak Albanian economy made Ahmet Zogu seek quick solutions to stabilize both the state and his regime. Albania started welcoming foreign financial capitals to solve its economic problems, which were also political. Meanwhile, the longtime competitors, Italy and Great Britain, through their powerful companies, tried to invest in strategic sectors of the Albanian economy. In this way, big international companies, such as the Anglo-Persian Oil Company, the Standard Oil Company, the powerful Italian company “Ferrovie dello Stato Italiano”, “Le Syndicat Franco-Albanais” representing the French capital etc., emerged in Albania. This created a political scene charged with tensions and ongoing negotiations between all the affected actors, including the Albanian state. In 1925, the aftermath of the international diplomatic efforts put under the spotlight the two main rivals for prevalence in Albania, Italy and Great Britain. While the first was directly and vitally concerned about Albania and the Balkans, the second was merely interested in the stability of the region. Speaking of Albania’s interests, in the achieved agreements with the different foreign companies, there were indeed a series of articles that were disadvantageous for the state and its economy. However, Ahmet Zogu made an utmost effort to play a significant role, above the real possibilities Albania had at that time.
Resetting the Ideological Clock: How the Russian-Ukrainian Issue Was Part of Bulgarian Discourse a Century Ago
Authors: Hadzhikosev Roman
Published: September 2023

This article examines the discussion, which took place in Bulgaria shortly after the beginning of the First World War, between the Austrian deputy of Ukrainian origin Longin Tsechelski and Nikola Bobchev and Yaroslav Romanchuk. At the end of 1914, Tsechelsky arrived in Sofia to campaign for the support of the Ukrainian people in the struggle for independence publishing a pamphlet "How Russia "liberates" Ukraine?". It accuses Russia of having provoked the war by deceiving Serbia; of using pan-Slavic propaganda promulgating the idea of a single Slavic race; of denying Ukrainian nation the right to self-determination because it is conceived as being part and parcel of the Russian people; of not accepting Ukrainian language and Ukrainian literature as different from the Russian language and Russian literature but were instead considered to be their adjuncts, and some other similar arguments.Russophile circles in the country were immediately prompted to take action, which resulted in a response to Tsechelski with an article by Nikola Bobchev and a brochure by Romanchuk, a Ukrainian living and working in Bulgaria. Naturally, they try to refute the claims by using well-known arguments, talking about the liberating role that Russia played in fighting against Ottoman „slavery“, the Slav solidarity and the commercial interests of the West and more specifically of Austria during that historical moment. In the following year, a new answer followed in a book of more than a hundred pages by Tsechelski and another one by Romanchuk.
Fair Trial for Transitional Justice: The Case of Belene Trial
Authors: Koçak Harun , Özgür Baklacıoğlu Nurcan
Published: September 2023

Inspired by the 32-years long Belene trial, the article investigates the impact of deprivation from the right to justice on reaching transitional justice in aftermaths of crimes against humanity. Through bottom-up victims-centered perspective the article digs into the Belene victims’ oral history narratives to find out the impact of this deprivation on the societal contract, victims’ trauma, justice perception of the society and the rule of law. Based on textual analysis of open-ended interviews and narratives of the Belene victims, the article highlights the adverse consequences of neglecting the victims’ right to fair trial and transitional justice and perpetuating impunity, not only impeding justice and healing but perpetuating victimization and corroding societal trust. The sustained denial of victims' rights to a fair trial and access to justice exacerbates historical wounds, erodes the foundations of the justice and collective perception of fairness in the whole society. Beyond legal implications, the deprivation from right to justice affects individuals' psychological and social well-being and overall societal peace. The article emphasizes that transitional justice is a moral imperative, enabling the rebuilding of a peaceful and democratic society on principles of accountability and empathy, especially in the complex and sensitive aftermath of ethnic-based crimes against humanity.

LOS SENTIMIENTOS EN ESCENA: UN ACERCAMIENTO ENTRE DOROTÉIA DE NELSON RODRIGUES Y LA CASA DE BERNARDA ALBA DE FEDERICO GARCÍA LORCA
Authors: Silva Filho J. F.
Published: September 2023

Este artículo pretende estudiar los sentimientos como el deseo y la envidia en dos obras teatrales modernas: La casa de Bernarda Alba de Federico García Lorca y Dorotéia de Nelson Rodrigues. Para este trabajo tomamos en cuenta que el teatro apela no solo a la imaginación sino además a la emoción ya que también busca despertar los sentimientos al público. Hemos dado énfasis, para desarrollarlo, a autores y obras que pautan en una visión mítico-poética, una vez que el trasfondo mítico nos toca no sólo el intelecto, sino otros niveles más profundos de nuestro ser, es decir, mueve anímicamente al lector/espectador a través de su polivalencia emocional.
LINGUAGEM AUDIOVISUAL: DOCUMENTÁRIO, REGISTRO FACTUAL OU REALIDADE FICCIONALIZADA?
Authors: Hidalgo João Eduardo
Published: September 2023

O artigo trata do documentário contemporâneo e dos limites e contatos entre o registro do real e a ficcionalização da realidade, presentes em algumas obras fundamentos do gênero, como a narrativa audiovisual se realiza. Obras como Hearts and minds (1974) de Peter Davis e Notícias de uma guerra particular (1999) de João Moreira Salles e Kátia Lund são analisadas e comparadas de acordo com as estratégias de registro do real que utilizam como entrevistas, uso de imagens de arquivos, construção de roteiro, uso do som direto e captação de imagens. O texto mostra que o cinema já tem em sua criação a artificialidade do registro de um dispositivo técnico na sua essência, o registro de um fato do cotidiano ‘real’, já passa pela escolha e montagem de um autor e representa um aspecto desta realidade. A ficção já é mais perceptível para o público pois ela se fundamenta na literatura, como é o caso de Room de 2015.
LETRAMENTO QUEER - UMA PRÁTICA PEDAGÓGICA ENGAJADA
Authors: De Jesus Meireles Teixeira Arielle
Published: September 2023

O presente capítulo defende a pertinência da prática pedagógica do Letramento Queer, uma vez que um dos papéis da escola é possibilitar que os seus cidadãos possam ter acesso aos seus direitos. Assim, compreende-se que o sistema educacional deve atuar em um processo emancipatório contra as práticas normalizadoras e sexistas da sociedade. Os autores Kalantzis, Cope e Pinheiro (2000) e Soares (2009) embasam a discussão quanto ao Letramento, enquanto que Street (2014) e Kleiman (1991) respaldam os apontamentos quanto ao multiletramento e as suas diversas práticas. Por fim, para tratar sobre o Letramento Queer utiliza-se como base teórica Louro (2016) e Miskolci (2012). O desenvolvimento da pesquisa defende que, apesar de complexo, o trabalho com o Letramento Queer é libertador e necessário para o atual contexto sócio histórico brasileiro em que tem-se presenciado a ascensão de uma agenda ultraconservadora na política.
Soret-Dufour Mechanisms on Unsteady Boundary Layer Flow of Tangent Hyperbolic and Walters-B Nanoliquid

Published: September 2023

Thermal radiation, chemical reaction, and Soret-Dufour produce effects on the tangential hyperbolic and waters-B nanoliquid unsteady flow which are explored in this work due to their applications in oil and gas industry, microfluidics, aerospace and heat transfer enhancement. With the special interests in the combined Joule heating as well as viscous dissipation, the flow equations is developed to model the transport of species and thermal energy. By utilising the non-dimensional similarity variables, the equations are reduced to their dimensionless PDE form. Using the spectrum relaxation technique (SRM), the new PDES is numerically solved. The Gauss-Seidel SOR method is used to decouple and linearize equation systems. The study is carried out by investigating the graphs as flow parameters vary. It was found that the Brownian motion parameter enhances the rate of heat transfer. Furthermore, by reducing the hydrodynamic boundary layer, the introduction of magnetism was observed to decrease the speed of fluid motion.

Published: September 2023

In this paper, analyze the impact of Activation energy, Diffusion thermo and nonlinear thermal radiation of mixed convection casson fluid flow through a vertical cone with porous material in the presence of Brownian and thermophoresis has been studied. Numerical techniques, namely Runge–Kutta integration and the shooting method, were applied to obtain solutions to similarity-transformed equations governing continuity, momentum, energy and concentration. The study examined the distributions of flow velocity, temperature and concentration under the interactive effects of the fluid. The results revealed that the activation energy of the Arrhenius equation plays an important role in fluid transport mechanisms within a chemically reactive system involving the Soret effect for a low-Schmidt-number fluid. When the activation energy parameter E was greater within the range 0 < E < 5, the wall shear stress was stronger, heat transfer rate increased, and mass transfer rate decreased.
Peculiar Orbital Characteristics of Earth Quasi-Satellite 469219 Kamo‘oalewa: Implications for the Yarkovsky Detection and Orbital Uncertainty Propagation
Authors: Hu Shoucun , Li Bin , Jiang Haoxuan , Bao Gang , Ji Jianghui
Published: September 2023

469219 Kamo‘oalewa is selected as one of the primary targets of Tianwen-2 mission, which is currently believed to be the most stable quasi-satellite of Earth. Here we derive a weak detection of the Yarkovsky effect for Kamo‘oalewa, givingA2= (−1.075 ± 0.447) × 10−13au day−2, with the available ground-based optical observations from Minor Planet Center and a relatively conservative weighting scheme. Due to the quasi-satellite resonance with Earth, we show that the detection of the Yarkovsky effect by orbital fitting with astrometric observations becomes difficult, as its orbital drift shows a slow oscillatory growth resulting from the Yarkovsky effect. In addition, we extensively explore the characteristics of orbital uncertainty propagation and find that the positional uncertainty mainly arises from the geocentric radial direction in 2010–2020 and then concentrates in the heliocentric transverse direction in 2020–2030. Furthermore, the heliocentric transverse uncertainty is clearly monthly dependent, which can arrive at a minimum around January and a maximum around July as the orbit moves toward the leading and trailing edges, respectively, in 2025–2027. Finally, we investigate a long-term uncertainty propagation in the quasi-satellite regime, implying that the quasi-satellite resonance with Earth may play a crucial role in constraining the increase of uncertainty over time. Such an interesting feature further implies that the orbital precision of Kamo‘oalewa is relatively stable at its quasi-satellite phase, which may also be true for other quasi-satellites of Earth.
Meteoritic Molybdenum and Ruthenium Isotopic Abundances Document Nucleosynthetic p-process Components
Authors: Marti Kurt , Fischer-Gödde Mario , Proksche Carina
Published: September 2023

Anomalies in isotopic abundances of Mo and Ru in solar system matter were found to document variable contributions of the nucleosynthetic s-process component. We report isotopic relations of ϵ
92Mo versus ϵ
100Ru in meteorites from chondritic parent bodies, iron meteorites, and achondrites that reveal deviations from expected s-process abundance variations. We show that two p-process isotopes 92Mo and 94Mo require the presence of distinct p-process components in meteoritic materials. The nucleosynthetic origin of abundant magic (N = 50) p-process nuclides, covering the mass range of Zr, Mo, and Ru, has long been an enigma, but contributions by several recognized pathways, including alpha and νp-antineutrino reactions on protons, may account for the observed relatively large solar system abundances. Specific core-collapse supernovae explosive regions may carry proton-rich matter. Since Mo and Ru isotopic records in solar system matter reveal the presence of more than one nucleosynthetic p-process component, these records are expected to be helpful in documenting different explosive synthesis pathways and the implied galactic evolution of p-nuclides.

⊙, such studies have primarily relied on the satellite galaxy population orbiting the Milky Way (MW). Here we present new constraints on the connection between satellite galaxies and their host dark matter subhalos using the largest sample of satellite galaxies in the Local Volume (D ≲ 12 Mpc) to date. We use 250 confirmed and 71 candidate dwarf satellites around 27 MW-like hosts from the Exploration of Local VolumE Satellites (ELVES) Survey and use the semianalytical SatGen model for predicting the population of dark matter subhalos expected in the same volume. Through a Bayesian model comparison of the observed and the forward-modeled satellite stellar mass functions (SSMFs), we infer the satellite stellar-to-halo mass relation. We find that the observed SSMF is best reproduced when subhalos at the low-mass end are populated by a relation of the form

A Small-scale Structure Model of a Jet Based on Observations of Microvariability
Authors: Xu Jingran , Hu Shaoming , Chen Xu , Jiang Yunguo , Alexeeva Sofya
Published: September 2023

We developed a multiregion radiation model for the evolution of flux and spectral index with time. In this model, each perturbation component in the jet produces an independent flare. The model can be used to study the decomposition of microvariability, the structural scale of the perturbed components, and the physical parameters of the acceleration processes. Based on the shock acceleration model for a relativistic jet, the influence of the acceleration parameters on multiband flare parameters is calculated. We present the results of multiband optical microvariability of the blazar BL Lacertae observed during 89 nights in the period from 2009 to 2021, and use them as a sample for model fitting. The results show that both the amplitude and duration of flares decomposed from the microvariability light curves conform to a log-normal distribution. The time delays between the optical bands follow a normal distribution and amount to several minutes, which corroborate with both predictions from the theoretical model and the calculation of the discrete correlation function. Using the spectral index evolution and the simultaneous fitting of the multiband variability curves, we obtain the acceleration and radiation parameters to constrain and distinguish the origins of different flares. Based on the flare decomposition, we can effectively reproduce the time-domain evolution trends of the optical variations and energy spectrum, and explain the various redder-when-brighter and bluer-when-brighter behaviors.

BACKGROUND: Extubation failure of patients on mechanical ventilation is relatively a frequent finding in the intensive care unit (ICU) and associated with poor prognosis.
AIM: We conducted this study in Critical Care Department, Cairo University hospitals in which we aimed to assess if there is advantage to use high flow nasal cannula (HFNC) or non-invasive ventilation (NIV) over conventional oxygen therapy (COT) in success of extubation of patients.
METHODS: The study included 60 patients and was randomized into three equal groups. The first group used HFNC, the second group used COT, while the third group used NIV. The reintubation rate, ICU stay, ICU mortality, and 28-day mortality were followed in all groups.
RESULTS: The all study population had a mean age of 62 ± 21, 31 patients were male, and 21 patients were smokers. SOFA score on admission, APACHE II, and SOFA pre-extubation was not significantly different in the three groups. Reintubation rate was higher in COT group compared to HFNC or NIV groups (p < 0.05). ICU stay was longer in COT compared to the other two groups, while ICU and 28-day mortality showed no significant difference among the all groups.
CONCLUSION: Use of HFNC and NIV was associated with lower reintubation rate, improved oxygenation and shorter ICU stay but no significant effect on mortality in comparison with COT.
Le choc des mondes : lecture puritaine du tremblement de terre de Londres (6 avril 1580)
Authors: Fernandes Isabelle
Published: September 2023

Le séisme de Londres du 6 avril 1580 a donné lieu à de multiples narrations populaires, préscientifiques et officielles qui tentèrent d’expliquer l’extra‑ordinaire. En vers ou en prose, moralisateurs ou médicaux, plus ou moins circonstanciés, les récits des puritains Thomas Twyne, Arthur Golding, Thomas Churchyard et Gabriel Harvey retranscrivent un éventail de réactions diverses face à la brutale intrusion de l’impensable dans le quotidien anglais. L’interprétation du tremblement de terre manifeste la domination d’une conception providentielle du monde. Si le paradigme biblique demeure prépondérant, le scepticisme naissant donne lieu à des interrogations pour l’heure inabouties. L’Église établie protestante et le gouvernement élisabéthain s’emparèrent de la catastrophe naturelle afin d’unifier le royaume et de contrer la menace catholique grandissante grâce à l’appui donné aux publications puritaines. Les puritains profitèrent de cette tribune pour défendre un programme religieux plus radical que la via media décidée. Le séisme fut le révélateur de lignes de faille irréparables entre deux visions du monde : celui d’hier et celui de demain.
At the Crossroads
Authors: Kincade Lolita L.
Published: September 2023

The proportion of women of color faculty members in academia is on the rise, and they are also more visible in higher education leadership. Yet, systemic sexism and racism, coupled with other forms of intersectional oppression, makes it difficult to advance to senior level administration. This chapter explores the lived experiences of academicians with intersecting identities and proposes a social ecological model to guide the development of effective interventions through social environments. Knowledge applied from personal inquiry, practical examples, and empirical evidence have resulted in important recommendations that are organized into five nested, hierarchical levels. These recommendations can help to improve diversity and inclusion efforts, and to achieve structural and systemic transformation across colleges and universities.
Applying the Triple Bottom Line for Corporate Sustainability Toward Zero Environmental, Social, and Economic Footprints in Corporate Practice
Authors: Rahim Emad
Published: September 2023

The mystification of the term sustainability with society's desiderata, desegregate sustainability into three types: social, economic, and environmental. The triple bottom line needs to be integrated into every stratum of the business for corporate responsibility. The optimal performance ensures sustainability and brings together strategies that relate to the environment and society. This chapter serves as a road map to bring about a zero triple bottom line, thus ensuring a sustainable business ecosystem. A sustainability strategy aligns business sustainability goals with environmental and social stewardship goals. Corporations need to create a synergistic relationship with key stakeholders and the global communities regarding the biosphere. A call of duty requires that corporations/firms need go beyond product stewardship into beneficial relationships relating to the communities and the Earth. Ample opportunities and significant challenges abound for organizations globally.

Education and Training represent the principal means through which individuals acquire skills and competences. And it is through participation in continuous professional development and learning that adults will access, on an ongoing basis, the upskilling and reskilling necessary to adapt to the continuous changes. The paper analyses the gathered information (Delphi analysis using specific surveys) that is necessary for the harmonization of the knowledge involved in the transition to the digital and green manufacturing. The analysis was applied to information received from specialists in fabrication from 5 EU countries, with different levels of industrial development: Belgium, Poland, Portugal, Romania, and Slovenia. According to the analysis, the majority of the responders (75%) did not receive training in digital and green activities in the past 6 months, 69% have participated in digital training. The companies which started the transformation to digital fabrication, use CAD-CAM followed by Enterprise resource planning (ERP), Production and Quality Management systems, communications tools and in a minor scale Robotic production technology, simulation tools and virtual programming digital monitoring. One of the problems identified with this survey was related to lack of digital skills experienced by the surveyed participant (44%) and lack of knowledge in digital training on the part of withe and blue co-workers (almost 80% in total). In terms of the use different digital technologies for the part of the companies it is equilibrated in terms of social media and Collaborative Technologies (30%); Data and Analytics (26%); Mobile Technologies (27%) and Cloud Computing Services (17%). The second part of the Delphi analysis was related on how to engage learners and help them to meet course and programme learning outcomes. Engagement entails includes mindfulness, intrinsic motivation, cognitive effort, and attention. To start with it was important to understand the way teaching/learning should be carried out, and the majority of the participants believed that Hybrid, online and face to face combined lectures are the best learning method, in terms of type of lesson, the short courses between 30-45 min were the most voted option (55%), followed by traditional 45 min lessons (30%).

Additive Manufacturing (AM) [1] is playing every day a bigger role in the automotive industry because of its cost competitiveness, short delivery lead times and potential for design flexibility and optimization. Plastics and polymers are the most common materials used to produce AM parts in this sector, however metal AM is increasing its importance as there are specific applications that require mechanical characteristics that can only be achieved with metals such as stainless steel, titanium, hard steel, copper, aluminum, and others. There is an increasing number of metal AM technologies and Original Equipment Manufacturers (OEMs) competing in the industry with a very widespread list of advantages and disadvantages of each of them. We are at a point where automotive manufacturers need to make a complex decision on which metal AM equipment to purchase. This paper describes the main metal AM technologies and highlight the advantages and disadvantages of each of them. Additionally, three of the most competitive Metal AM technologies are compared: Powder Bed Fusion (PBF), Metal Filament Deposition Modeling (MFDM) and Bound Metal Deposition (BMD) on a specific experimental sample. For this study, a very common and representative automotive part has been chosen that is well suited to be printed in metal and can be manufactured in the three chosen technologies. A nozzle from the automotive body plant used to distribute accuratey a sealant bead onto a body panel before the final assembly operation was selected. These sample parts have been trialed for function and evaluated in general terms from a quality point of view. The conclusions included in this paper will help the automotive industry players understand which technology to use for this specific part and other parts with similar characteristics. Additional work will focus on specific quality characteristics such as material composition, mechanical properties, dimensional accuracy, and specific defects found to compare these technologies in detail. Furthermore, a selection of other automotive parts and technologies will be necessary to enlarge the knowledge on the application of metal AM on this field.

Recent research has highlighted structural and functional abnormalities in the cerebral cortex of patients with premature ejaculation (PE). These anomalies could play a pivotal role in the physiological mechanisms underlying PE. This study leveraged functional magnetic resonance imaging (fMRI), a noninvasive technique, to explore these neural mechanisms. We conducted resting-state fMRI scans on 36 PE patients and 22 healthy controls (HC), and collected data on Premature Ejaculation Diagnostic Tool (PEDT) scores and intravaginal ejaculation latency time (IELT). Employing a surface-based regional homogeneity (ReHo) approach, we analyzed local neural synchronous spontaneous activity, diverging from previous studies that utilized a volume-based ReHo method. Areas with significant ReHo differences between PE and HC groups underwent surface-based functional connectivity (FC) analysis. Significant discrepancies in ReHo and FC across the cortical surface were observed in the PE cohort. Notably, PE patients exhibited decreased ReHo in the left triangular inferior frontal gyrus and enhanced ReHo in the right middle frontal gyrus. The latter showed heightened connectivity with the left lingual gyrus and the right orbital superior frontal gyrus. Furthermore, a correlation between ReHo and FC values with PEDT scores and IELT was found in the PE group. Our findings, derived from surface-based fMRI data, underscore specific brain regions linked to the neurobiological underpinnings of PE.

Numerous soft faults in SRAM memory emerge as technological innovations scales down, resulting in single and several cell upsets. The increased use of transistors in space applications has rendered semiconductor devices more vulnerable to soft errors caused by harm from radiation. A single event upset (SEU) is occurring whenever a soft error produces a tiny bit flipped in a storage device. Because SEU faults affect system performance, they must be addressed as soon as possible. Error-correcting codes, like the method known as (7,4) hamming codes, were devised and their decoding and encoding procedures were verified. It also used to detect single errors that can be fixed. It also helps detect double errors, SECDED however repair of double errors is tough. The decoding and encoding techniques of these approaches were investigated, and all computational findings had been verified and executed in a Xilinx NEXYS 4 DDR FPGA board.
