Los hombres de Franco en Barcelona. Los procesos de selección de gobernadores civiles en la dictadura franquista (1960-1966)
Authors: Sanz Hoya Julián 
Published: February 2024

Los gobiernos civiles constituyeron la principal institución de la dictadura franquista para asegurar el control social y desplegar sus políticas en las provincias, y el Gobierno Civil de Barcelona fue, sin duda, el de mayor relevancia. Por ello la historiografía ha dedicado una especial atención a la significación y la gestión de los gobernadores-jefes provinciales, que gozaban de extensas competencias y una amplia discrecionalidad. Sin embargo, no conocemos mucho sobre cómo se producían los ceses y, sobre todo, los nombramientos de los gobernadores, cómo y quiénes seleccionaban los posibles candidatos y qué factores se valoraban en este tipo de decisiones. Con el objetivo de atender estas cuestiones, este artículo se centra en los procesos de relevo y nombramiento de gobernadores de Barcelona que se gestaron durante los años iniciales e intermedios de la década de 1960, usando para ello documentación inédita de archivo procedente del Ministerio de la Gobernación. Con ello, se pretende conocer mejor estos procesos, las relaciones entre Gobernación y la dirección del partido único (FET-JONS), los candidatos valorados y los motivos para todo ello. Los resultados pueden contribuir a entender mejor el funcionamiento de las lógicas internas de poder en la dictadura, atendiendo a las pugnas y las interrelaciones entre proyectos y culturas políticas, instituciones y clientelas.
Versatile terahertz metasurface: dynamic switching between electromagnetically induced transparency and perfect absorption
Authors: Zhang Shuzhao , Qi Yunping , Zhou Zihao , Shi Qiang , Wang Li , Luo Bing 
Published: February 2024

This paper introduces a versatile metasurface based on vanadium dioxide (VO2) and graphene that seamlessly transitions between electromagnetically induced transparency (EIT) and multi-band absorption through VO2’s phase change property. When VO2 is in a dielectric state, the device can generate EIT. This configuration allows dynamic tuning of the central frequency by adjusting the graphene’s Fermi levels (E
f
), achieving a remarkable group delay of 1.42 ps. When VO2 is in a metallic state, the structure facilitates a Fabry–Perot resonance between the VO2 layer at the bottom and the graphene layer at the top, leading to exceptional light absorption. Specifically, absorptivity of 99.8% and 99.4% is achieved at 1.66 THz and 2.87 THz, respectively. In addition, these two resonance peaks can also be dynamically adjusted by modulating E
f
. Furthermore, the device serves as a highly sensitive sensor with sensitivity up to 0.65 THz/RIU. Notably, both absorption and EIT modes are polarization-insensitive and exhibit tolerance to a wide range of incidence angles. Consequently, the proposed device holds significant promise across various applications within the electromagnetic field, including tunable devices, absorbers, sensors, slow-light devices, and so on.

Background
Dysbiotic biliary bacterial profile is reported in cancer patients and is associated with survival and comorbidities, raising the question of its effect on the influence of anticancer drugs and, recently, the suggestion of perichemotherapy antibiotics in pancreatic cancer patients colonized by the Escherichia coli and Klebsiella pneumoniae.

Objective
In this study, we investigated the microbial communities that colonize tumours and which bacteria could aid in diagnosing pancreatic and biliary cancer and managing bile-colonized patients.

Methods
A retrospective study on positive bile cultures of 145 Italian patients who underwent cholangiopancreatography with PC and EPC cancer hospitalized from January 2006 to December 2020 in a QA-certified academic surgical unit were investigated for aerobic/facultative-anaerobic bacteria and fungal organisms.

Results
We found that among Gram-negative bacteria, Escherichia coli and Pseudomonas spp were the most frequent in the EPC group, while Escherichia coli, Klebsiella spp, and Pseudomonas spp were the most frequent in the PC group. Enterococcus spp was the most frequent Gram-positive bacteria in both groups. Comparing the EPC and PC, we found a significant presence of patients with greater age in the PC compared to the EPC group. Regarding Candida spp, we found no significant but greater rate in the PC group compared to the EPC group (11.7% vs 1.96%). We found that Alcaligenes faecalis was the most frequent bacteria in EPC than the PC group, among Gram-negative bacterial species.

Conclusions
Age differences in gut microbiota composition may affect biliary habitats in our cancer population, especially in patients with pancreatic cancer. Alcaligenes faecalis isolated in the culture of bile samples could represent potential microbial markers for a restricted follow-up to early diagnosis of extra-pancreatic cancer. Finally, the prevalence of Candida spp in pancreatic cancer seems to trigger new aspects about debate about the role of fungal microbiota into their relationship with pancreatic cancer.

Published: February 2024

Objective
To generate a mouse model carrying TTNtv Y4370* simulating the newly discovered human heterozygous nonsense TTNtv c.13254T>G (p.Tyr4418Ter) to supplement and improve the functional evidence of pathogenic mutation TTNtv c.13254T>G on the pathogenic type of dilated cardiomyopathy.

Methods
We generated 4 mice carrying TTNtv p. Y4370* through CRISPR/Cas-mediated genome engineering. Monthly serological detection, bimonthly echocardiography, and histology evaluation were carried out to observe and compare alterations of cardiac structure and function between 4 TTN+/- mice and 4 wild-type (WT) mice.

Results
For the two-month-old TTN+/- mice, serum glutamic-oxalacetic transaminase (AST), lactic dehydrogenase (LDH), and creatine kinase (CK) were significantly increased, the diastolic Left Ventricular Systolic Anterior Wall (LVAW), and the LV mass markedly rose, with the left ventricular volume displaying an increasing trend and Ejection Fraction (EF) and Fractional Shortening (FS) showing a decreasing trend. Besides, the histological evaluation showed that cardiac fibrosis level and positive rate of cardiac mast cell of TTN+/- mice were obviously increased compared with WT mice.

Conclusions
TTNtv Y4370* could lead to cardiac structure and function alterations in mice, supplementing the evidence of TTNtv c.13254T>G pathogenicity in human.

Authors: Kopittke Manoela Kasper , Monticelli Jefferson Marlon , Dal-Soto Fábio , Garrido Ivan Lapuente 
Published: February 2024

Objetivo: Este estudo analisa as principais dimensões da Orientação Empreendedora (OE) – propensão à inovação, propensão ao risco e proatividade – que contribuíram para o crescimento das micro, pequenas e médias empresas (MPMEs) durante a crise causada pela Covid-19.
Metodologia: Foi realizada uma análise quantitativa por meio de teste t pareado com 102 gestores de MPMEs para perceber quais os principais aspectos da OE que contribuíram para o desempenho das suas empresas.
Resultados: Os resultados mostram que a presença de um elemento proativo nas MPMEs influencia o aumento das suas receitas em período de crise da pandemia. No entanto, não se confirma a importância das características de propensão à inovação e ao risco nas MPMEs para o seu crescimento em período de crise.
Limitações: A amostra utilizada nesta pesquisa poderia ser maior e o conceito de OE é baseado apenas em suas três dimensões principais. Como não há consenso na literatura sobre a dimensionalidade do construto de OE, outras aplicações com o uso dos diferentes conceitos são sugeridas.
Implicações teóricas e práticas: A pesquisa mostra como a OE impulsiona as MPMEs em um contexto de crise, notadamente por meio de sua dimensão proatividade. De forma prática, o artigo revela que a OE nas MPMEs está fortemente presente na figura do líder, assim como está relacionada à sua personalidade, o qual desempenha um papel importante para impulsionar o negócio em um período de crise.
Originalidade: Este estudo permite identificar quais aspectos da OE são mais decisivos no crescimento das MPMEs em períodos de recessão generalizada. Assim, os empreendedores poderão avaliar o quanto consideram as perspectivas dominantes da OE para o crescimento de seus negócios. Também contribui tanto para a discussão sobre a recuperação da economia quanto para a literatura sobre OE, que ainda não mostra como esse constructo opera em contexto de crise.
Operating Efficiency in the Capital-Intensive Semiconductor Industry: A Nonparametric Frontier Approach
Authors: Qiao Guangshun , Lu Yulin 
Published: February 2024

Abstract
This article uses a nonparametric production frontier approach to investigate the operating efficiency differences by the impacts of capital expenditure and business model in the global semiconductor industry. Handling the impact of capital expenditure as a fixed input by the directional distance estimator, this study compares the operating efficiencies in the global semiconductor industry between the integrated device manufacturers and the fabless and foundry firms over 1999–2018. The estimation results indicate that the operating efficiencies do vary in the semiconductor by the business model. The vertically integrated manufacturers dominate the semiconductor industry, and the capital-intensive manufacturers operate more efficiently than the asset-light fabless firms on average.

Published: February 2024

Abstract
The purpose of the current study was to examine Japanese preservice professionals’ socialization experiences while working with mothers and infants during midwifery practicum experiences. This study utilized an interpretive case study research design (Merriam, Sharan B. 1998. Qualitative research and case study applications in education. San Francisco, CA: Jossey-Bass). Data were collected from reflective journals (Janesick, Valerie. 1999. A journal about journaling: Writing as a qualitative research technique history issues and reflections. Qualitative Inquiry 5(4). 505–524) and electric portfolios. Participants were ten female students enrolled in a midwifery certification program at one private university located in central Tokyo in Japan. A constant comparative analysis method was used to interpret the data, with four themes emerging from the data: (a) struggling to make decisions related to lesson procedures, (b) adjusting lesson content to meet mothers’ and infants’ unique needs, (c) paying less attention to partners’ roles and responsibilities, and (d) applying knowledge and skills to future midwifery settings. Results indicated that the preservice professionals struggled to prepare and plan lessons and activities in a timely manner, and had the challenge of modifying activities based on the infant’s unexpected and unpredictable behaviors. However, the preservice professionals believed that the practicum course was beneficial for their professional learning and development, and applicable to various educational and professional settings. In order to advance the quality of practicum experiences in the midwifery program, instructors, department chairs, and researchers need clear and focused goals related to the status, quality, and relevance of the midwifery program mission and curricula. Due to the paucity of research in this area, it is essential to further explore these issues in Japan.

Abstract
Ti6Al4V alloy is a commonly used α + β alloy among titanium alloys. In this study, in order to improve the oxidation resistance of the Ti6Al4V alloy, Ti–Al – based aluminum coating was deposited to the surface by the pack cementation method. The aluminizing process was carried out in an open atmosphere oven at 700 °C for 4 and 6 h. It has been observed that the coating layer thickness varies between 13 and 17 µm depending on the duration of cementation process. From XRD analysis, it has been detected the TiAl3, TiAl2, and TiAl phases on the coating layer. Aluminum coated and untreated Ti6Al4V alloys were subjected to oxidation tests at 800, 850, and 900 °C for 4, 20, and 40 h. The obtained nonlinear weight gain characteristic has been modeled to determine the coating status of the samples. It was determined that the highest weight gain was in the untreated sample. Using the provided model, samples were classified in terms of coating condition by systematic approach based on weight gain profile versus time. Oxidation tests also supported with DTA and TG analyses.

Abstract
A green analytical chemistry study attempts to generate environmentally friendly alternatives to dangerous compounds while reducing waste output. The study thoroughly analyzed eight green tools to determine their greenness. Given its importance in treating hallucinations and delusions produced by Parkinson’s disease psychosis, it is critical to have a reliable and precise method for identifying pimavanserin (PVS) in both pure form and pharmaceutical formulations. The current study used a straightforward approach to forced degradation experiments to establish a novel reversed-phase high-performance liquid chromatography method for evaluating stability. The method was executed on the Agilent Zorbax Eclipse Plus C18 column (100 × 4.6 mm, 3.5 μm particle size) with ultraviolet detection at 226 nm. The Box–Behnken design is the ultimate solution for identifying optimal chromatographic conditions in a timely and efficient manner, with minimal trials required. The study investigated the impact of three factors: acetonitrile ratio, column oven temperature, and flow rate on various responses, namely, retention time, tailing factor, and theoretical plates. Desirability and overlay plots were utilized to forecast the best mobile phase containing a buffer solution: acetonitrile: tetrahydrofuran in a ratio of (65: 20: 15, v/v/v), which proved highly effective in the experiments. Linearity was conducted for PVS in the 3–50 µg·mL−1 range with an R
2 coefficient of determination of 0.9997. PVS had detection and quantification limits of 1.1 and 3.5 µg·mL−1, respectively, indicating a highly significant correlation between the variables studied. PVS’s recovery percentage was determined to be 101.30%. We also used the Six Sigma lean technique to ensure precision and productivity. PVS was tested for acid, base, oxidative hydrolysis, photodegradation, and heat, as per International Council for Harmonisation guidelines. The highest degradation was obtained from oxidative hydrolysis and thermal degradation.
Eric Mascall and the making of an Anglican Thomist, 1937–1945
Authors: Webster Peter 
Published: February 2024

Abstract
This article examines the early career of E. L. (Eric) Mascall, Anglican Catholic priest, theologian and philosopher of religion, late of Christ Church Oxford and King’s College London. Mascall spent the years between 1937 and 1945 teaching at Lincoln Theological College, in a time of acute political and intellectual unsettlement and (in due course) world war. Mascall rebelled against the previously dominant liberalism of the 1930s while also rejecting both Barthian Protestantism and certain currents in Orthodox theology, both of which were products of the same turmoil. The article documents his turn instead to the natural theology of Thomas Aquinas, and examines both its sources and its particular articulation in Mascall’s work. Even though relatively few in England followed Mascall down this particular path, his formation in the 1930s and 1940s reveals much about the temper of the moment.

Mortar Workability Apparatus: A New Approach
Authors: Tresouthick SW , Dubovoy VS , Gajda JW 
Published: February 2024

Abstract
The ability to accurately determine the workability and board life of mortars has been an important goal of the cement industry. This paper describes a new approach for more accurate determinations of the workability and board life, as well as other mortar properties, which has recently been developed. This simple approach uses a computerized mechanical apparatus to numerically measure the properties of fresh mortar. Data derived from this method have been shown to correlate well with characteristics observed by a professional mason during parallel tests. This new device provides results that are more reproducible, reliable, and accurate than results from periodic penetration tests.
Aggregate Mixtures for Least-Void Content for Use in Polymer Concrete
Authors: Kantha Rao VVL , Krishnamoothy S 
Published: February 2024

Abstract
Over 350 mixtures of quartzite aggregate with locally available pit sands have been made in the laboratory, and the proportions of fine aggregate for 34 least-void content mixtures have been obtained experimentally. Plots have been made between the proportion of aggregate fraction finer than largest size fraction and the fineness modulus of such a fraction. The proportions required for least-void content followed a linear trend fairly similar to what one would obtain from the theoretical gradings of Fuller, Weymouth, or Ehrenberg, but the actual proportions of fine fractions were somewhat lower than those obtained from such hypotheses. Reasons for the difference are discussed.
An empirical equation has been fitted for this linear trend so that it can be used to determine the proportions of coarse and fine aggregates of least-void contents. Based upon Powers' modification of Butcher's and Hopkins' equation, the nature of particle interference in aggregate mixtures has been discussed. The experiments have also shown that use of gap-graded or sands of restricted sieve sizes results in reduced particle interference when compared with using fine aggregates of continuous grading, even though aggregate mixtures having gap-graded fine aggregates may have slightly higher values of void ratio.
The experiments were extended to study the optimum microfilier content needed to fill some of the remaining voids of the system. The amount of microfilier that can be used before further particle interference takes place is obtained by one of the three methods suggested, including the use of Powers' equation as modified in this work.
Mixtures of coarse and fine aggregates and microfilier with least possible void ratios are preferred for making polymer (resin) concretes.

Authors: Tarafder S , Tarafder M , Ranganath VR 
Published: February 2024

Abstract
The linear-elastic deformation behavior of the standard chord-supported arc bend, A(B)-C, specimen has been modeled using the finite element method (FEM) in order to generate displacement and compliance data for wide ranges of geometric variables. Using these data, stress intensity factor (SIF) expressions, and crack mouth compliance (CMC) and compliance crack length (CCL) relations have been developed for the A(B)-C geometry. The accuracies of the developed fracture mechanics expressions have been determined with respect to the FEM data and were found to be within ±0.75% maximum. Against data and expressions available in the literature, the accuracies of the developed relations were evaluated and found to be satisfactory.
Minimum Thickness Requirements for Rockwell Hardness Testing
Authors: Heberling TG , Fee AR , Tobolski EL 
Published: February 2024

Abstract
A study was performed in an attempt to resolve the conflicting thickness requirements for Rockwell hardness testing specified in ASTM Standard Test Methods E 18-93 and in ISO Standard 6508. Commercial standardized hardness test blocks were machined to “steps” of various thicknesses using a wire EDM (electrical discharge machining) process. Rockwell hardness tests were performed on the original standardized surface of these “stepped” blocks in an attempt to determine the minimum thicknesses required for reliable Rockwell hardness testing. The extremes of test force and hardness were investigated for both the diamond brale and 1/16 in. (1.588 mm) ball indenters.
