description: ABSTRACTThe holotype of the sauropod dinosaur Rebbachisaurus garasbae was discovered in infra-upper Cenomanian horizons of the Kem Kem region of southeastern Morocco in the 1940s and 1950s. The original materials included part of a vertebral column, some of which was found in articulation, and a scapula, a humerus, and an ischium. Of these remains, only the scapula and one of the dorsal vertebrae have been described, but in abbreviated form. Following complete preparation of the partial skeleton, careful examination and fitting of scores of fragments collected with these materials, and computed tomography imaging of the most complete vertebra, we present a complete description of the holotype of Rebbachisaurus garasbae. Our description identifies several autapomorphies of the dorsal and caudal vertebrae, both relating to the shape of the vertebrae and the architecture of their laminae. Based on our reassessment of its anatomy, Rebbachisaurus is recovered as a member of an Afro-European clade that includes Nigersaurus and Demandasaurus. Due to the large size of one of its dorsal vertebrae (ca. 1.45 m tall), Rebbachisaurus has been considered to be a large sauropod. The size of the vertebral centra and the length and cross-sectional area of the humerus of Rebbachisaurus, however, indicate this individual weighed 7915–12,015 kg, which is slightly larger than Amargasaurus but comparable in size to some individuals of Dicraeosaurus. The dorsal vertebrae of Rebbachisaurus and other rebbachisaurids have been suggested to be highly mobile, but results suggest that anatomical features of the vertebrae actually limited rotation and increased resistance to dorsoventrally directed forces applied to the transverse processes.SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP

description: Interaction of organic molecules with the surface of metals plays important role in many applications. In particular, surface protective applications need much explanation from both experimental and theoretical point of view. Herein, we have investigated the surface adsorption characteristics and corrosion inhibition behavior of two new benzimidazole derivatives namely 2-(2-Bromophenyl)-1H-benzimidazole (BPBA) and 2-(2-Bromophenyl)-1-methyl-1H-benzimidazole (BPMA) on mild steel in 0.5 M HCl solution using experimental and theoretical approach. Electrochemical and weight loss experiments were used to elucidate the corrosion inhibition potentials of BPBA and BPMA. Attenuated total reflectance-Fourier transform infrared spectroscopy, contact angle, scanning electron microscopy, and X-ray photoelectron spectroscopy measurements were performed to confirm the adsorption of BPBA and BPMA on mild steel surface. Computer simulations were further employed to provide additional insights into the mechanism of interaction between the inhibitors and the steel surface. All the results confirmed that BPMA is a better corrosion inhibitor for mild steel than BPBA in 0.5 M HCl. This new inhibitors could find application industrially during processes such as oil well acidizing for steel protection against corrosion.

description: In this study, we have theoretically demonstrated the intrinsic ability of the wobble G·T(w)/G*·T*(w)/G·T(w1)/G·T(w2) and Watson–Crick-like G*·T(WC) DNA base mispairs to interconvert into each other via the DPT tautomerization. We have established that among all these transitions, only one single G·T(w) ↔ G*·T(WC) pathway is eligible from a biological perspective. It involves short-lived intermediate – the G·T*(WC) base mispair – and is governed by the planar, highly stable, and zwitterionic transition state stabilized by the participation of the unique pattern of the five intermolecular O6+H⋯O4−, O6+H⋯N3−, N1+H⋯N3−, N1+H⋯O2−, and N2+H⋯O2− H-bonds. This non-dissociative G·T(w) ↔ G*·T(WC) tautomerization occurs without opening of the pair: Bases within mispair remain connected by 14 different patterns of the specific intermolecular interactions that successively change each other along the IRC. Novel kinetically controlled mechanism of the thermodynamically non-equilibrium spontaneous point GT/TG incorporation errors has been suggested. The mutagenic effect of the analogues of the nucleotide bases, in particular 5-bromouracil, can be attributed to the decreasing of the barrier of the acquisition by the wobble pair containing these compounds of the enzymatically competent Watson–Crick’s geometry via the intrapair mutagenic tautomerization directly in the essentially hydrophobic recognition pocket of the replication DNA-polymerase machinery. Proposed approaches are able to explain experimental data, namely growth of the rate of the spontaneous point incorporation errors during DNA biosynthesis with increasing temperature.

description: BackgroundThis paper aims to empirically test a comprehensive interrelationship among green supply chain management (GSCM), green technology innovation (GTI), waste management (WM), big data analytics capability powered by artificial intelligence (BDAC-AI), and their collective impact on sustainable performance (SP) in organizational contexts.
MethodThis study has been conducted in food processing sector of Pakistan. The respondents include 495 managers working in the food processing industry. A structural equation modeling (SEM) approach is used to examine direct and indirect relationships between the variables. Originality occurs when the integration of TAM and DCT is looked at to understand sustainable practices in the context of the provided model.
ResultsThe research of this paper highlights that GSCM, GTI, WM, and BDAC-AI have a positive, strong, and direct impact on SP. Furthermore, GTI and WM only partially mediate the link between GSCM and SP, whereby the two moderate the link. Also, BDAC-AI shows the moderation effect on the relationship between GTI and SP.
ConclusionThis study has managerial implications, including strategies that involve using theoretical frameworks in technological acceptance and dynamic capabilities to support sustainable initiatives. However, it is worth noting that the findings provide a practical contingency for managers and businesses interested in implementing green studies effectively, improving technologies, and strengthening capabilities for sustainable performance. This research adds value in that the paper first integrates TAM and DCT to explain sustainable operations and their impact on organizations. Further, it extends the existing literature by establishing the relationship between GSCM and SC. It offers a model through which GSCM can be operationalized in the context of the FS sector.

description: The photodegradation of the herbicide fenuron (1,1-dimethyl-3-phenylurea) by using a natural iron oxide (NIO), α-Fe2O3, in aqueous solution at acidic pH has been undertaken. The NIO was characterized by the Raman spectroscopy method. The degradation pathways and the formation of degradation products were studied. A high-pressure mercury lamp and sunlight were employed as light source. Fenuron photodegradation using NIO with oxalic acid followed the pseudo-first-order kinetics, the optimal experimental conditions were [oxalic acid]0 = 10−3 M and [NIO] = 0.1 g L−1 at pH 3. A UVA/NIO/oxalic acid system led to a low fenuron half-life (60 min). The results were even better when solar light is used (30 min). The variables studied were the doses of iron oxide, of carboxylic acids, the solution pH and the effect of sunlight irradiation. The effects of four carboxylic acids, oxalic, citric, tartaric and malic acids, on the fenuron photodegradation with NIO have been investigated, oxalic acid was the most effective carboxylic acid used at pH 3. A similar trend was observed for the removal of total organic carbon (TOC), 75% of TOC was removed. The analytical study showed many aromatic intermediates, short-chain carboxylic acids and inorganic ion.

Decision-making under uncertainty in short-term electricity markets
Creators: name: Kraft, Emil
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2022

description: In the course of the energy transition, the share of electricity generation from renewable energy sources in Germany has increased significantly in recent years and will continue to rise. Particularly fluctuating renewables like wind and solar bring more uncertainty and volatility to the electricity system. As markets determine the unit commitment in systems with self-dispatch, many changes have been made to the design of electricity markets to meet the new challenges. Thereby, a trend towards real-time can be observed. Short-term electricity markets are becoming more important and are seen as suitable for efficient resource allocation. Therefore, it is inevitable for market participants to develop strategies for trading electricity and flexibility in these segments. The research conducted in this thesis aims to enable better decisions in short-term electricity markets. To achieve this, a multitude of quantitative methods is developed and applied: (a) forecasting methods based on econometrics and machine learning, (b) methods for stochastic modeling of time series, (c) scenario generation and reduction methods, as well as (d) stochastic programming methods. Most significantly, two- and three-stage stochastic optimization problems are formulated to derive optimal trading decisions and unit commitment in the context of short-term electricity markets. The problem formulations adequately account for the sequential structure, the characteristics and the technical requirements of the different market segments, as well as the available information regarding uncertain generation volumes and prices. The thesis contains three case studies focusing on the German electricity markets. Results confirm that, based on appropriate representations of the uncertainty of market prices and renewable generation, the optimization approaches allow to derive sound trading strategies across multiple revenue streams, with which market participants can effectively balance the inevitable trade-off between expected profit and associated risk. By considering coherent risk metrics and flexibly adaptable risk attitudes, the trading strategies allow to substantially reduce risk with only moderate expected profit losses. These results are significant, as improving trading decisions that determine the allocation of resources in the electricity system plays a key role in coping with the uncertainty from renewables and hence contributes to the ultimate success of the energy transition.

description:  

This preliminary study proposes a novel pharmacological approach for the treatment of Overactive Bladder (OAB) using a combination of a beta-blocker (atenolol) and an alpha-blocker (terazosin). The objective is to reduce bladder muscle overactivity by modulating adrenergic signaling . This dual therapy aims to improve bladder storage function and reduce urgency symptoms. The hypothesis is supported by physiological mechanisms involving sympathetic neurotransmission, ATP co-release, and smooth muscle contraction pathways. Preliminary personal observations in a limited patient group have shown encouraging results. Further studies are needed to confirm these findings in larger cohorts.

description: This study investigated how inert supporting electrolytes (SEs), which increase the electrical conductivity, affect electrochemical ozone production (EOP) on a boron-doped diamond (BDD) electrode. Regardless of the SE species, the EOP was suppressed about 60% in a SE concentration of 1 mM for which the conductivity is similar to that of tap water compared to deionized water. The production of H2O2, which is known to be generated by the combination of , was also suppressed. On the other hand, the formation of was not significantly affected by the presence of SEs, an intermediate for ozone production. Consequently, suppression of EOP by SE can be explained by physical interference from the diffusion or combination of by the SE anions concentrated near the electrode surface. This study contributes by providing a better mechanistic understanding of the effect of SEs on EOP in a solid polymer electrolyte/BDD system.

description: The characterization of breeding systems enables to identify the types of breeding in order to elaborate development activities. The aim of this study was to characterize the types of local chicken breedings of Benin. Thus, 216 local chicken breeders of the twelve departments of Benin were interviewed. Three Types of breeding were identified. The Type 1 corresponds to livestock breeders who are not provided with schooling and includes farmers, artisans and housewives. They are distributed in almost all departments of Benin and constitute 77.78% of the survey population. The average herd size is 33 chickens and veterinary treatments or health follow-up are not practiced. In Type 2, the farmers are not provided with schooling; only a few have the primary or secondary standards. These farmers are more concentrated in Alibori, Atacora and Donga. This type of breeding regroups mostly housewives who do a food crops. The average herd size is 27 chickens and the sick birds are not usually treated. The sale of animals is not primordial. Farmers in this group represent 16.68% of the sampled population. Finally, in the Type 3, breeders have a high school standard and do agriculture as dominant activity. They represent 5.5% of the sampled population and practice their activities in north Benin. The herds are of large scale (92 heads) and the animals profit from a good medicare by administration of vitamin complex, antibiotics, vaccines and deworming based on veterinary requirements. Improving local chicken breeding must take into account the particularity of each breeding type.

Towards scalable steady LoRa networks: performance prospects from link level to system level
Creators: name: Bouazizi, Yathreb
Publisher: name: Imperial College London
Year: 2023

description: With a plethora of applications perpetually expanding to shore up different business use cases, the IoT ecosystem is continuously growing to underpin a wide variety of "Things". In response to this growth, the Low Power Wide Area Networks (LPWAN) paradigm has emerged, encompassing an array of technologies designed to extend network coverage, support low data rates, and consume less power. Among the LPWAN, LoRa has particularly attracted the attention of research and industrial communities thanks to the opportunity it offers to stakeholders to build private IoT infrastructures while reconciling range, power, and cost. However, with an unplanned deployment model and uncoordinated communications in the license-free spectrum, LoRa could face scalability issues. Characterising the scalability of LoRa networks and revealing what impacts it and how it trades with other performance KPIs are fundamental steps in engineering well-provisioned LoRa networks. Unlike its licensed counterparts, LoRa is a new technology with a patented physical layer that relies on several tuneable parameters. While beneficial to answer the requirements of different IoT scenarios, these parameters bring more challenges to LoRa modelling, performance estimation, and scalability characterisation. This thesis explores LoRa and provides a comprehensive picture of its link-level and system-level performance. From a link-level perspective, we deeply investigate LoRa signal theory and modulation scheme. Our study reveals and quantifies the non-orthogonality of LoRa modulation. From a network-level standpoint, we use the outcome of the link-level analysis to devise meticulous, more accurate analytical frameworks to evaluate the performance of large-scale LoRa networks. The proposed analytical frameworks uniquely join stochastic geometry and queueing theory to reflect both device-level and network-level, account for the access restriction to the shared medium, which is a significant challenge for license-free technologies, and comprehensively evaluate the interplay between different performance indicators in LoRa-based IoT networks under both static and dynamic SF allocations.

Calls for dialogue to address Zimbabwe’s multi-layered political, social and economic crises have been numerous, repeated and diverse. Yet, the attempts to date have consistently failed to sustain long-term activity and results. At the community level, by contrast, there is a rich culture of dialogue to engage and resolve disputes. Though varying in scope and subject, these dialogues represent a bottom-up approach where local constituents are not just participants but drivers of conversation and change.

This publication contains findings from an investigation of 13 diverse community dialogues in Zimbabwe that took place between 2017 and 2023 at the ward, village, or district level. It seeks to 1) identify successful positive strategies for non-partisan, community-level dialogue and 2) consider their potential replication at the national level to help catalyse meaningful issue-based dialogue among different actors, including political ones.

By delving into the nuances of these local dialogues, the study offers insights into the mechanisms that foster agreement and resolution, the challenges and barriers encountered, and the strategies that drive long-term success.

description: I approach the question of scales and political imaginaries through an exploration of how the Canadian province of Quebec is situated at the crossroads of several European and North American traditions. I discuss the relationship between the 2012 Quebec student strikes against the policies of then-Quebec premier Jean Charest and a welfare state model based on social protection, which is closer to that that found in France and several Scandinavian countries than in the rest of Canada. I then examine in depth how Quebec’s attempt to develop an alternative approach for the management of ethno-cultual diversity – often called interculturalism – has come to stand for a variety of political projects over time, despite using the same term to characterise them. Instead, interculturalism is a term which successive Quebec governments have long promoted but never defined nor explicitly framed as official policy. It is based on the power to regulate almost all migration into Quebec’s territory, which the provincial government has gradually acquired through a series of accords with the Canadian government from 1971 to 1991. I provide a detailed examination of the four main ‘phases’ of interculturalism since the 1970s. More generally, I offer reflections on how the Quebec case could help anthropology think through wider questions of institutionalisation, forms of government political culture and scale in order to understand political imaginaries.

description: Статья посвящена проблеме оспаривания соглашений об уплате алиментов в делах о банкротстве плательщиков алиментов как сделок, причиняющих вред кредиторам. Специфика банкротства граждан заключается в том, что, в отличие от банкротства юридических лиц, у должников-банкротов могут иметься специальные кредиторы – дети. В силу ст. 80 СК РФ родители обязаны содержать своих детей. Часто в делах о банкротстве должника, являющегося плательщиком алиментов, сталкиваются интересы детей, которые имеют право на содержание со стороны родителей, и интересы других кредиторов. Арбитражные суды, рассматривающие дела о банкротстве граждан – плательщиков алиментов, должны находить баланс между данными интересами: удовлетворять заявления об оспаривании соглашений об уплате алиментов только в той части, в которой размер алиментов превышает размер, необходимый для удовлетворения разумных потребностей ребёнка (разумный размер). Автор статьи представляет анализ судебной практики арбитражных судов и показывает два подхода,
имеющихся по вопросу оспаривания соглашений об уплате алиментов.

description: In the unforgiving environment of space, astronauts must be prepared to handle any disruption, foreseen or unforeseen, that threatens the safety and integrity of their habitat. From micrometeorite impacts to moonquakes, these disruptions can lead to catastrophic consequences if not addressed quickly. The challenge lies in ensuring that the necessary repair strategies are available when needed—without exceeding the limited area in the spacecraft. This thesis focuses on the concept of the probability of availability, an important parameter that helps mission planners determine how much inventory of safety controls should be packed for long duration space missions. Using probability models, we explore how different probabilities of disruptions and multiple repair strategies can affect the availability of repair tools and supplies. We have developed a model that identifies the initial inventory of implementation strategies required to mitigate various hazards. Our findings reveal that balancing crew safety with inventory constraints is not straightforward. Packing too few repair materials, even with a low probability of disruptions, could lead to disastrous outcomes. Conversely, overpacking wastes cargo space. This research demonstrates how the probability of availability model allows mission planners to make data-driven decisions that ensure a crew’s safety while taking cost and weight limits into consideration. The probability models for the inventory management of implementation strategies can be applied to other industries where inventory management is crucial. We emphasize how careful planning of the initial inventory, informed by probability models, could mean the difference between life and death in extreme environments.

description: Infrared high-resolution imaging and interferometry show that the dust distribution is frequently elongated along the polar direction of an AGN. In addition, interferometric mm line observations have revealed a bipolar outflow in a direction nearly perpendicular to the nuclear disk. To explain these findings, we developed a model scenario for the inner ∼30 pc of an AGN. The structure of the gas within this region is entirely determined by the gas inflow from larger scales. We assumed a rotating thick gas disk between about one and ten parsec. External gas accretion adds mass and injects energy via gas compression into this gas disk and drives turbulence. We extended the description of a massive turbulent thick gas disk developed in a recent paper by adding a magnetocentrifugal wind. Our disks are assumed to be strongly magnetized via equipartition between the turbulent gas pressure and the energy density of the magnetic field. In a second step, we built 3D density cubes based on the analytical model, illuminated them with a central source, and made radiative transfer calculations. In a third step, we calculated mid-infrared (MIR) visibility amplitudes and compared them to available interferometric observations. We show that magnetocentrifugal winds starting from a thin and thick gas disk are viable in active galaxy centers. The magnetic field associated with this thick gas disk plays a major role in driving a magnetocentrifugal wind at a distance of ∼1 pc from the central black hole. Once the wind is launched, it is responsible for the transport of angular momentum and the gas disk can become thin. A magnetocentrifugal wind is also expected above the thin magnetized gas disk. The structure and outflow rate of this wind is determined by the properties of the thick gas disk. The outflow scenario can account for the elongated dust structures, outer edges of the thin maser disks, and molecular outflows observed in local AGN. The models reproduce the observed terminal wind velocities, the scatter of the MIR – intrinsic X-ray correlation, and point source fractions. An application of the model to the Circinus galaxy and NGC 1068 shows that the infrared spectral energy distribution, available MIR interferometric observations, and optical polarization can be reproduced in a satisfactory way, provided that (i) a puff-up at the inner edge of the thin disk is present and (ii) a local screen with an optical depth of τV ∼ 20 in form of a local gas filament and/or a warp of the thick disk hide a significant fraction of both nuclei. Our thick disk, wind, thin disk model is thus a promising scenario for local Seyfert galaxies.

description: A range of stainless steels, nickel–chromium and nickel–chromium–molybdenum alloys were exposed to coastal seawater from Mandapam (Indian Ocean) and freshwater from a perennial pond. Biofilms from both test waters produced an ennoblement of the open circuit potential (OCP) on all alloys as expected, which was slower but substantially larger in freshwater. In both waters an interesting relationship was perceived between the plateau OCP (Emax) and the mass percentage of the major alloying elements. In particular, iron exhibited strong positive correlations with Emax (r2 ≥ 0.77; p r2 ≤ –0.81; p = 0.0002). Consistent with the regression analyses, Euclidean distance clustering yielded patterns where Inconel-600 and the nickel–chromium–molybdenum alloys had the smallest similarities of OCP with other alloys. The results emphatically reinforce a key role for surface passive films in the ennoblement phenomenon in natural waters.

description: Several of most common dermatoses worldwide, e.g., psoriasis and atopic dermatitis, are worsened in their clinical picture when the skin is regularly exposed to an increased air pollution level, e.g., particulate matter. This is explainable by the activation of the aryl hydrocarbon receptor (AhR) in the skin, which results in an increased release of proinflammatory cytokines and matrix metalloproteinases. Symurban is a competitive AhR antagonist and thus allows the effective protection of skin. In order to improve its dermal bioavailability as a poorly soluble active agent (0.25 µg/mL), nanocrystals were prepared and evaluated. Nanocrystals are pure active crystals reduced in particle size to the submicron range of 100 to 1000 nm. They feature the properties of nanocrystals, such as increased saturation solubility and dissolution velocity, without having to be declared as nanomaterial. Production methods and parameters were systematically investigated. Wet bead milling at 2000 rpm for 30 min yielded the best results. A z-average of 280 nm was achieved for a 10% Symurban suspension with a polydispersity index of 0.20, indicating a narrow size distribution. For the long-term stabilization of the nanocrystal suspension, the performance of 15 surfactants of different categories and HLB values were investigated and evaluated. It was found that non-ionic surfactants in general were better able to stabilize the system than anionic or amphoteric surfactants. Highest stability of over 12 months at 25 °C was achieved with 2% Plantacare 810 UP, an ECOCERT surfactant with high skin tolerance. The suspension was also chemically long-term stable with >97% of remaining Symurban over 12 months. The saturation solubility of Symurban as nanocrystals was significantly increased from 0.25 to 2.9 μg/mL, which corresponds to a factor of >11. In a case study of one male volunteer with healthy skin conditions, penetration profiles of Symurban nanocrystal hydrogel and commercial anti-pollution serum containing an identical amount of Symurban were determined and compared. After 20 min of exposure, the relative Symurban concentration in the deeper skin layers (tape 19-30) was more than two times higher for nanocrystal hydrogel (16%) than the commercial serum (7%). These results suggest that nanocrystals are a promising delivery system for the poorly soluble anti-pollution agent Symurban.

description: Two new groups of azobenzene ester derivatives were synthesised: alkyl 4-[4-(nonyloxy)phenyl]diazenyl]benzoates and 4-[4-(nonyloxy)phenyl]diazenyl]phenyl alkanoates. All 35 presented homologues are mesogenic. Moreover, some of the above-mentioned compounds exhibit rich liquid-crystalline polymorphism likewise tetramorphism. During this investigation by the use of polarising optical microscopy, differential scanning calorimetry and X-Ray studies, six types of mesophases were detected: nematic, smectics (A, C, I, F) and G. Furthermore, due to the presence of the photosensitive azo moiety, the E–Z isomerisation reaction is possible. This process, which is initiated by the UV irradiation, causes significant changes in the UV-Vis absorption spectra of investigated compounds. However, the photoisomerisation is a reversible process and in the dark the thermal relaxation of Z isomer takes place. Based on the achieved data, the kinetic constants of the isomerisation and relaxation processes were calculated. It shows that conversion of the ester bond makes some changes in the optical properties. The shift of about 7 nm of the absorbance maximum was observed. Surprisingly, the inversion of the ester group has significant influence on the liquid-crystalline polymorphism replacing one mesophase (for benzoates) into four (for alkanoates).
