This study analyzes the monitoring of public procurement contracts’ performance in six countries under EU public procurement rules: Finland, Portugal, Slovenia, Italy, Hungary, and Serbia. Through an in-depth comparative analysis, we explore the nexus between perceived corruption in these countries and the contract performance monitoring systems established or in the making.
The analysis centers on four key aspects: the organizational framework, the redress system, the IT infrastructure, and the level of data publicity in each country’s procurement landscape. Expert evaluations conducted by national specialists unveil which countries pay less attention to public contract performance monitoring and transparency.
Our findings indicate that countries facing higher corruption rates tend to place greater emphasis on transparency and contract performance monitoring. Moreover, countries greatly differ in their organizational setup, objectives, and monitoring tools, including IT adoption.
The insights derived from this study can influence policy and reform efforts focused on the contract phase of public procurement, leading to a more accountable and efficient procurement landscape across Europe.

Human vaccination is a complex process that engages social actors, products, infrastructures, and ideology. We explore the role of trust in the healthcare system for immunization with the seasonal influenza vaccine. We use data from a probabilistic national representative survey among Romanian adults 18 years old or older (n = 2115) fielded in 2019. Binary logistic regression modeling shows that probability of vaccinating against seasonal influenza is higher when the participants trust the overall healthcare system [Odds Ratio = 1.36,
p ≤ 0.001], discussed, and gathered information about vaccines [OR = 3.12, p ≤ 0.001], had positive evaluations of the vaccination services [OR = 2.19,
p ≤ 0.001], and evaluate today’s vaccine as being safer [OR = 3.05, p ≤ 0.001] or at least as safe [OR = 2.11, p ≤ 0.001] than those from the past. Results suggest that trust in the family physicians is built through personal experiences with them which can be easily adjusted in contrast with overall trust in the healthcare system. Increasing the quality of vaccines and vaccination and emphasizing vaccines’ benefits and safety is not sufficient but just the tip of the iceberg; the entire healthcare system needs a serious facelift which will make it trustworthy.
Nuovi dati dal settore a Ovest del tempio D
Authors: D’Andrea Francesca
Published: March 2024

Il settore a ovest del Tempio D, posto sulla propaggine meridionale della collina dell’antica  Akragas, era rimasto finora escludo dal dibattito scientifico. Questo contributo offre i primi  risultati delle ricerche archeologiche condotte nel 2022 come prosecuzione della fortunata  campagna di scavo dell’anno precedente. Lo studio si concentra principalmente su due  strutture murarie in grandi blocchi di calcarenite, per comprenderne la tecnica costruttiva, la  cronologia, i rapporti funzionali e topografici esistiti con il vicino tempio dorico. Le evidenze  emerse durante le indagini restituiscono interessanti dati sull’occupazione del santuario tra età  tardo-arcaica e l’impianto del grande cantiere per la costruzione del tempio dorico del V  secolo a.C.

Separarsi dall’antico. Agrigentum Kerkent Girgenti
Authors: Mangione Donatella
Published: March 2024

Tra i continui rivolgimenti politici e sociali del medioevo, la Sicilia viene più volte occupata da genti straniere che ne modificano cultura e costumi, a volte scompaginando gli assetti abitativi delle antiche città. A questo fenomeno non è estranea Agrigento: essa assiste all’alternarsi di domini di etnie diverse, dai romani ai vandali, bizantini, musulmani, normanni, mutando il suo nome, che da Agrigentum diviene Kerkent e infine Girgenti. L’insediamento urbano si modifica e, dalla valle in cui si era sviluppata la città greco-romana, si sposta a Nord, sul colle ‘di Girgenti’. Argomento del contributo è la disgregazione della città greco-romana e l’insediarsi del primo nucleo di popolazione sulla collina fino al Trecento quando, con la potenza feudale dei Chiaromonte, le mura urbiche vengono ampliate inglobando le pendici sud-orientali del colle, ormai dunque interamente occupato.

This research is concerned with the problems of students in mahārah al-qirā'ah at MTsN 3 Palu City whose problems include what are the problems of students in class VIII mahārah al-qirā'ah at MTsN 3 Palu City and what are the solutions to the problems of class VIII students at MTsN 3 Palu City in mahārah al-qirā'ah.

This research uses qualitative research methods and uses a descriptive approach. The results of the research show that first, the author divides problems from a linguistic perspective at MTsN 3 Palu City into four, namely sound system, sentence structure, vocabulary and writing. Meanwhile, problems from a non-linguistic perspective are divided into four, namely environmental factors, interest and motivation, educational factors, and facilities and infrastructure factors. Second, the solution or effort made by the teacher to overcome this problem is to spell out the words word by word to the students which is then followed up so that the pronunciation of the words is correct, such as pronouncing makhārijul hurūf, asking students to memorize the 14 dhamir, and giving them Arabic texts to rewrite. Meanwhile, the solution from a non-linguistic perspective is to provide motivation, vary learning methods, give prizes, and hold extra hours. Keywords: Makhārijul hurūf, Dhamir, Mahārah al-Qirā'ah
Economic value assessment of industrial heritage in Tangshan, China
Authors: Li Aimin , Wahid Wahiza Binti Abdul , Isa Mohd Jamil Bin Mat , Lu Mengtian
Published: March 2024

Industrial heritage is a legacy from the past that we live with today and pass on to future generations. The economic value of this heritage can be defined as the amount of welfare that it generates for society, and this value should not be ignored. However, current research based on economic analysis has mostly focused on qualitative statements instead of quantitative assessment. This study proposes an innovative methodology combining qualitative (field research) and quantitative (willingness to pay and contingent valuation) methods to assess the economic value of industrial heritage. The industrial heritage of Tangshan, China, was chosen as a case study, and the research found that museums and cultural creative parks are effective ways to conserve industrial heritage. The entrance fee can be used to represent the economic value of the heritage site. There was a positive correlation between the influence of economic value and the entrance fees residents would prefer to pay. The results indicate the locals would prefer lower entrance fees for the transformed heritage museums (The average current cost: $2.23). Locals were most concerned about the entrance fees for the Kailuan Coal Mine and Qixin Cement Plant Museums, which have both been renewed as urban landmarks for city tourism. Renewal methods have been applied to six industrial heritage sites in Tangshan; these sites have their own conservation and renewal practices based on city-level development or industrial attributes. Thus, when residents recognize the economic value of a heritage site, they are willing to pay a higher entrance fee. This research demonstrates the economic value of industrial heritage using a mixed methods approach and provides a basis for assessing the value of cultural heritage for urban tourism analysis.

Analysis of the feasibility of using biopolymers of different viscosities as immobilization carriers for laccase in synthetic dye removal
Authors: Białowąs Małgorzata , Kończak Beata , Chałupnik Stanisław , Kalka Joanna
Published: March 2024

The main aim of the study was to assess the feasibility of using biopolymers of different viscosities (high, medium and low viscosity) as immobilization carriers for laccase in synthetic dye removal. The following dye solutions were decolorized: indigo carmine (IC, anionic dye), methylene blue (MB, cationic dye), and their mixture in a molar mass ratio MB/IC=0.69, using biopolymers of different viscosities as laccase immobilization carriers. Toxicity tests were also carried out to assess the toxicity of the post-decolorization samples. Decolorization tests showed that the main decolorization mechanism depends on the dye class. The removal of IC (max. total removal efficiency 72.15%) was mainly by biocatalysis. The mechanism of the MB decolorization process was mainly by sorption on alginate beads, and the efficiency of enzymatic removal was low. However, the highest efficiency of MB decolorization (45.80%) was obtained for beads prepared using the high viscosity alginate when decolorization occurred by both sorption and biocatalysis. The results of mixture decolorization tests differ from the results obtained for single dyes.The results showed differences in the efficiency of the dye sorption process depending on the alginate used for immobilization. Moreover, the varying mechanisms of dye removal from the dye mixture were confirmed by toxicity tests. The occurrence of both biocatalysis and sorption promotes reduced toxicity

Published: March 2024

The aim of the study was to assess the feasibility of utilizing sodium alginate biopolymer as animmobilization carrier for laccase in the removal of indigo carmine (IC), an anionic dye. The main goal of this work was to optimize the decolourization process by selecting the appropriate immobilized enzyme dose per 1 mg of dye, as well as the process temperature. The effective immobilization of laccase using sodium alginate as a carrier was confirmed by Raman spectroscopy. An analysis of the size and geometric parameters of the alginate beads was also carried out. Tests of IC decolourization using alginate-laccase beads were conducted. Applying the most effective dose of the enzyme (320 mg of enzyme/1 mg of IC) made it possible to remove 92.5% of the dye over 40 days. The optimal temperature for the IC decolourization process, using laccase immobilized on sodium alginate, was established at 30-40ºC. The obtained results indicate that laccase from Trametes versicolor immobilized on sodium alginate was capable of decolourizing the tested dye primarily based on mechanism of biocatalysis.
The effect of fermentation modes on the efficiency of organic waste treatment in batch bioreactors
Authors: Hovorukha Vira
Published: March 2024

The amount of solid organic waste is constantly growing. This is caused by the growth of industrial and agricultural capacities, and the inefficiency of existing waste processing technologies. Biotechnologies can provide effective environmentally friendly solutions for waste treatment. Therefore, the goal of our work was to compare the efficiency of strictly anaerobic fermentation of multi-component solid organic waste with hydrogen synthesis and waste treatment with pulsed air access in batch bioreactors.During fermentation, the following parameters were controlled: pH, redox potential (Eh), concentration of dissolved organics, and the content of H2, O2, and CO2 in the gas phase. The efficiency was evaluated via the process duration, calculation of the ratio of the initial and final weight of waste (Кd), and the yield of molecular hydrogen. Obtained results revealed high efficiency of organic waste degradation in both variants. The weight of waste 83-fold and 86-fold decreased, respectively. The time required for fermentation in strictly anaerobic conditions was 4 days, whereas 7 days were required for the mode with pulsed air access. The first variant provided a 2.8-fold higher hydrogen yield (54±4,1 L/kg of waste), and the second one provided a decrease in the concentration of dissolved organic compounds in the fermentation fluid. Fermentation is the effective approach for accelerated degradation of solid organic waste. Strictly anaerobic fermentation appeared to be useful in the need to accelerate the process. The mode with the pulsed air access can provide not only degradation of solid waste but also purification of the fermentation fluid.
Societal and strategic perspectives of ex post project evaluation
Authors: Kozień Ewa , Stanuch Marcin
Published: March 2024

The implementation of public projects by organizations requires professionalization of their evaluation methods. The research objective is to identify the key criteria for project evaluation that go beyond the “project triangle.” The following problem was formulated: whether ex post evaluation of the project taking into account parameters of the “design triangle” is not an oversimplification in the context of uniqueness of design solutions that significantly affect civilization and technological development of societies in terms of global. The study was conducted in two stages. In the first stage, 109 completed projects were evaluated using the quantitative method. The quantitative method was used to evaluate the projects. In the second stage, on the basis of the project-evaluation results, the key criteria for ex post evaluation of project implementation were analyzed using the Hellwig’s correlation method. It was shown that for the proper ex post evaluation of project implementation, it is necessary to supplement criteria with strategic and societal effects.

Authors: Meireles Wallace , Rangel Janinne , Antonialli Graziela , Medina Cristina , Silva Romina
Published: March 2024

Hemangioma is the most common vascular tumor of childhood. It may present as multiple cutaneous hemangiomas on rare occasions, with or without visceral involvement. The condition of lesions restricted to the skin is called benign neonatal hemangiomatosis, and in the case of visceral lesions associated with cutaneous lesions, the denomination is disseminated or diffuse neonatal hemangiomatosis (DNH). For the diagnosis of DNH, three criteria must be met: onset in the neonatal period, involvement of three or more organs, and absence of malignancy in hemangiomas. ASAS, a full-term, vaginally delivered newborn, weight: 3560g, length: 52cm, head circumference: 35cm, APGAR: 9/9. Maternal history of syphilis during pregnancy - mother adequately treated in pregnancy. At birth, she presented with purpuric lesions of variable size on the chest, limbs, feet, and hands, which discolored under digital pressure; larger lesions with relief, not scaly. He developed severe heart failure and was admitted to the Neonatal Intensive Care Unit (NICU) in a secondary hospital in the Federal District. Imaging tests were performed: Computed tomography of the skull, thorax, and total abdomen, which revealed the presence of a possible hemangioma in the left frontal lobe, telangiectasias in the lungs, and multiple hepatic hemangiomas. He had a clinical diagnosis of DNH. The case described corroborates the fact that knowledge about the disease is relevant, as early diagnosis can lead to more accurate approaches that may reduce morbidity and mortality from the disease.
Kawasaki disease with atypical initial symptoms: a case report
Authors: Vieira Tami , Ton Bárbara , Oliveira Marcella , Carlesso Gabriela , Silva Sara
Published: March 2024

Introduction: Kawasaki disease (KD) is an acute, self-limited, systemic vasculitis of unknown etiology. The diagnosis is essentially clinical and the treatment is based on the use of intravenous human immunoglobulin (IVIG) and acetylsalicylic acid (ASA) in anti-inflammatory dose, being ideally initiated by the tenth day of the onset of symptoms in order to avoid the complications associated with this pathology. Metodology: This is a case report of a 9-year-old child with Kawasaki syndrome with atypical initial presentation. Discussion: Previously healthy child, presenting febrile jaundice hemorrhagic syndrome and influenza syndrome, associated with radiological changes that could be correlated with SARS-COV-2 infection, without initially ruling out the hypothesis of Pediatric Multisystemic Inflammatory Syndrome (SIM-P). After negative serologies and cultures, there was a progressive remission of symptoms, except for the fever. Criteria for KD were met on the 16th day of evolution, when monotherapy with ASA without IVIG was initiated, with resolution of the fever. Conclusion: It is essential to be aware of the possible variations in the clinical presentation of KD and correlate it with the epidemiological and social context of the patient, due to the morbidity related to this vasculitis.
Historias subterráneas: Tesis del cuento de Ricardo Piglia en dos relatos latinoamericanos
Authors: Díaz Hernández Dunielys
Published: March 2024

El crítico y teórico argentino Ricardo Piglia postula dos ideas fundamentales en  las “Tesis sobre el cuento” publicadas en su libro Formas Breves: un cuento siempre narra dos historias y la segunda es la clave de la forma del relato y sus variantes. Desde esta perspectiva, el presente artículo sugiere una mirada crítica y acuciosa en dos cuentos de autores latinoamericanos: Canto y baile del escritor chileno Manuel Rojas y Tobías del narrador, poeta y ensayista cubano Félix Pita Rodríguez. Con ese instinto detectivesco que, según Piglia, acompaña a la crítica literaria, se intentará llegar a la historia secreta en ambos relatos, a partir del análisis de los detalles y guiños cifrados en los intersticios de los textos.

An Electrochemical Series for Materials
Authors: Mueller Tim , Montoya Joseph , Ye Weike , Lei Xiangyun , Hung Linda , Hummelshøj Jens , Puzon Michael , Martinez Daniel , Fajardo Chris , Abela Rachel
Published: March 2024

The electrochemical series is a useful tool in electrochemistry, but its effectiveness in materials chemistry is limited by the fact that the standard electrochemical series is based on a relatively small set of reactions, many of which are measured in aqueous solutions. To address this problem, we have used machine learning to create an electrochemical series for inorganic materials from tens of thousands of entries in the Inorganic Crystal Structure Database. We demonstrate that this series is generally more consistent with oxidation states in solid-state materials than the series based on aqueous ions. The electrochemical series was constructed by developing and parameterizing a physical, human-interpretable model of oxidation states in materials. We show that this model enables the prediction of oxidation states from composition in a way that is more accurate than a state-of-the-art transformer-based neural network model. We present applications of our approach to structure prediction, materials discovery, and materials electrochemistry, and we discuss possible additional applications and areas for improvement.

Around two-thirds of chronic human disease is not explainable by genetics alone. The Lancet Commission on Pollution and Health estimates that 16% of global premature deaths are linked to pollution. Additionally, it is now thought that humankind has surpassed the safe planetary operating space for introducing human-made chemicals into the Earth System. Direct and indirect exposure to a myriad of chemicals, known and unknown, poses a significant threat to biodiversity and human health, from vaccine efficacy to the rise of antimicrobial resistance as well as autoimmune diseases, and mental health disorders. The exposome chemical space remains largely uncharted due to the sheer number of possible chemical structures, estimated at over 10^60 unique forms. Conventional methods have cataloged only a fraction of the exposome, overlooking transformation products and often yielding uncertain results. In this perspective we have reviewed the latest efforts in mapping the exposome chemical space and its sub-spaces. We also provide our view on how the integration of data driven approaches might be able to bridge the identified gaps.

Solid-state NMR, XRD, mechanical strength measurements, quantification of bound water and isothermal calorimetry were combined to contrast the reaction paths followed by slag under the influence of three alkaline activators: NaOH, Na2CO3, and Na2Si1.7O4.4. NaOH-activation led to the concomitant formation of a very ordered C-A-S-H gel and of hydrotalcite, giving rise to early mechanical strength. For Na2Si1.7O4.4, a N-A-S-H gel formed first due to the high quantities of silicon in solution. This led to quick setting but no mechanical strength. Later, an amorphous C-A-S-H gel provided mechanical strength, while an aluminate phase precipitated. Finally, Na2CO3-activation led also to the formation of N-A-S-H favored by the initial consumption of calcium to form calcite. This did not bring any real structuration and mechanical strength to the paste. Only after a few days of hydration did the mechanical strength improve with the precipitation of amorphous C-A-S-H, an ill-defined hydrated aluminate phase, and gaylussite.

Protein-protein interactions (PPIs) regulate crucial physiological and pathological processes. PPIs are considered a class of biological targets almost infeasible for small molecules because the binding surfaces are usually large and shallow. Peptides are molecules able to bind to these drug targets; they can be used as modulators and mimic one of the interaction partners. This review details the advances in in silico peptide design and experimental approaches for the evaluation of PPI-based peptides.
Suppressing sidechain modes and improving structural resolution for 2D IR spectroscopy via vibrational lifetimes
Authors: Hess Kayla , Rohler Cade , Buchanan Lauren
Published: March 2024

Vibrational spectroscopy of protein structure often utilizes 13C18O-labeling of backbone carbonyls to further increase structural resolution. Sidechains such as arginine, aspartate, and glutamate absorb within the same spectral region, however, complicating the analysis of isotope-labeled peaks. In this study, we report that the waiting time between pump and probe pulses in two-dimensional infrared spectroscopy can be used to suppress sidechain modes in favor of backbone amide I’ modes based on differences in vibrational lifetimes. Further, differences in the lifetimes of 13C18O-amide I’ modes can aid assignment of secondary structure for labeled residues. Using model disordered and β-sheet peptides, it was determined that while β-sheets exhibit a longer lifetime than disordered structures, while amide I’ modes in both secondary structures exhibit longer lifetimes than sidechain modes. Overall, this work demonstrates that collecting 2D IR data at delayed waiting times, based on differences in vibrational lifetime between modes, can be used to effectively suppress interfering sidechain modes and further identify secondary structures.

Sodium superionic conductors (NASICON) are pivotal for the functionality and safety of solid-state sodium batteries. Their mechanical properties and ionic conductivity are key performance metrics, yet their interrelation remains inadequately understood. Addressing this gap is vital for concurrent enhancements in both properties. This study summarizes recent literature on NASICON solid electrolytes Na1+xZr2SixP3-xO12 (NZSP, 0≤x≤3), highlighting the mechanical properties and ionic conductivity, and identifies a positive correlation between mechanical strength, in particular hardness, and ionic conductivity at ambient temperatures. Microstructural analysis reveals that a range of factors, including relative density, grain size, secondary phases, and crystallographic structures, significantly influence material properties. Notably, an increase in relative density uniquely contributes to simultaneous enhancements in both ionic conductivity and mechanical strength. Consequently, future research should prioritize enhancing the relative density of NASICON solid electrolytes, possibly employing advanced techniques, including sol-gel process, spark plasma sintering (SPS), and microwave-assisted sintering. The correlation between mechanical properties and ionic conductivity observed in NASICON solid electrolytes extends to other high-temperature sintered oxide electrolytes like Li7La3Zr2O12 (LLZO). This investigation not only suggests a potential linkage between these crucial properties but also guides subsequent strategies for refining solid electrolytes for advanced battery technologies.

We report the design and synthesis of high affinity and selective sulfonate-binding imprinted polymers using tweezer type functional monomers featuring parallel two imidazolium sites and phenyl sulfonic acid (PSA). The complexation in the pre-polymerization complex and stoichiometry of the bis-imidazolium functional monomer with PSA was evaluated by UV, 1H NMR titration supported by modeling. The combination of hydrophobic phosphorus hexafluoride counter anion to the imidazolium functional moieties and the lipophilic template phenyl sulfonic acid in tetrabutylammonium salt form in acetonitrile have produced extremely tight recognition binding sites combined with ionic and C-H hydrogen bond donors within imprinted polymers. Results from rebinding isotherm assays found that polymers displayed remarkable affinity to PSA with Ka = 104 to 105 M-1 in organic as well as aqueous solvents. The binding pocket of the developed receptor showed unprecedented selectivity for PSA when imprinted polymers competed with equimolar quantities of isosteric analytes, i.e., phenyl sulfonic acid and phenyl phosphonic acid.
