Published: July 2022

Abstract
Modification of metal surfaces with complex molecules opens interesting opportunities to build additional functionality into these surfaces. In this work, self assembled monolayers (SAMs) based on the same photoswitchable azobenzene motif but with different head groups have been synthesized and their SAMs on Au(111)/Si substrates have been characterized. 3-[(4-phenylazo)phenoxy]propyl thiol (PAPT) and its acetyl group protected analog, 3-[(4-phenylazo)phenoxy]propyl thioacetate (PAPA), have been synthesized. SAMs from PAPT and PAPA have been characterized by infrared (IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), ellipsometry and cyclic voltammetry (CV). The SAM-forming units of both SAMs are the same, as confirmed by IR and XPS, and the SAMs have similar surface coverage, as evidenced by analysis of the reductive desorption peaks in CVs. The tilt angle of the azobenzene moiety was ca. 75° with respect to the surface normal as determined by IR spectroscopy, i.e., the molecules are lying quite flat on the gold surface. Despite similar surface coverages, the CVs for PAPT in aqueous perchlorate solution show a typical perchlorate adsorption peak to gold, whereas the corresponding experiments with PAPA show no perchlorate adsorption at all. In conclusion, SAM formation can lead to an increase in the number of electrochemically accessible surface sites on the final, SAM covered surface. Whether the amount of such sites increases or decreases, depends on the precursor. The precursor most likely affects the adsorption mechanism and thus the atomic surface structure of the metal at the metal/SAM interface. Thus, details of the SAM formation mechanism, which is affected by the precursor used, can have quite strong effects on the electrochemical properties, and likely also electrocatalytic properties, of the resulting modified surface.

Abstract
Morgan, B, Mirza, AM, Gimblet, CJ, Ortlip, AT, Ancalmo, J, Kalita, D, Pellinger, TK, Walter, JM, and Werner, TJ. Effect of an 11-week resistance training program on arterial stiffness in young women. J Strength Cond Res 37(2): 315–321, 2023—The current investigation was conducted to determine the effect of 2 resistance training models on indices of arterial stiffness in young, healthy women. Twenty-four women, untrained college students, aged 18–22 years were randomized into 1 of 3 groups: control (CON) group (n = 8), high-intensity (HI) resistance exercise group (n = 8), and high-volume (HV) resistance exercise group (n = 8). Subjects randomized to resistance training groups were required to perform strength training exercises 3–5 days a week for 11 weeks. The exercise regimen consisted of 2–3 sets of 3–8 repetitions (80–90% of 1 repetition maximum [1RM]) for the HI group and 3–4 sets of 10–15 repetitions (50–70% of 1RM) for the HV group. All subjects were instructed to continue their normal diet and avoid cardiovascular exercise during the study. After the intervention, there was a significant increase in carotid femoral pulse wave velocity (PWV) (6.39 ± 0.73 to 8.40 ± 2.31 m·s−1; p < 0.05) and carotid radial PWV (9.77 ± 1.74 to 12.58 ± 2.09 m·s−1; p < 0.05) in the CON group alone. Both the HI and HV groups increased their maximum squat (36.6 ± 7.9 vs. 41.3 ± 31.8 percent change; p < 0.05), bench press (34.4 ± 12.6 vs. 23.4 ± 11.1 percent change; p < 0.05), and seated row (22.0 ± 12.6 vs. 21.9 ± 12.5 percent change; p < 0.05), respectively. Our findings support the use of resistance training exercise without undue impact on vascular compliance in otherwise healthy women.

Se realiza una breve introducción histórica sobre los factores que impulsaron la ocupación de territorios durante la colonia y cómo esas localizaciones, motivadas por intereses económicos y políticos, además del desconocimiento del medio, favorecieron la expansión desordenada de asentamientos marginales en áreas urbanas en tierras con limitaciones naturales sensibles y efectos ambientales severos. Se enfatiza, entonces, en la necesidad de implementar instrumentos de planificación como los planes reguladores.
una Carla Lonzi: a Feminist Critique to Sexual Difference in Hegel’s Ethical State
Authors: Locatelli Silvia 
Published: July 2022

Within contemporary philosophical discourse we find different thinkers that, with the aim to criticize Western dominant thought, by them addressed as ‘phallocentric’, directly refer to Hegelian texts. This paper will present one author who have openly spoken out a feminist critique of Hegelian thought, and in particular of the sexual division described by the Stuttgart philosopher, culminating in the ethical state – representing the constitution of the modern state – with the confinement of the feminine within the domestic sphere and, conversely, the liberation of the masculine within community political life.
The thinker who will be analyzed is the Italian activist and philosopher Carla Lonzi, author of the renowned Sputiamo su Hegel (Let’s Spit on Hegel) and precursor of the Italian sexual difference feminism. The author confronted the political division implemented by Hegel within the ethical state between the two sexes, trying to show how Hegel’s work strongly contributed to the constitution of the patriarchal symbolic order still in force in Western thought. The fundamental point of the author’s thought is, in fact, the conviction that the symbolic and linguistic structures of Western culture are something deeply rooted and, therefore, very complex to change. This helps us to understand why in Europe, despite the implementation of various legislative changes – such as, for example, the establishment of anti-violence centers, the recognition of gender violence at a legal level, the sanctions against gender discrimination in the workplace – the patriarchal dynamics typical of Western thought are changing too slowly (when they are): gender violence is the order of the day, the pay gap is far from being healed, and, above all, the division of gender roles between care work and productive work is still strongly present.
This text, therefore, seeks to demonstrate that the philosophical scope that accompanied the formation of European thought also characterized its darker features, including the patriarchal perspective. Here, we will analyze a particular aspect of patriarchy, focusing on its elaboration within Hegelian political philosophy: the presumed ontological and biological/natural destination of the female to domestic work and the male to public life.
To this end, the article is divided into two parts. In the first part, the concept of sexual difference as developed by Hegel will be presented, analyzing its development within the three parts of his philosophical system. In the second part, a part of Lonzi’s thought will be briefly analyzed, to then articulate her critique of the Hegelian division of gender roles.

BACKGROUND
Antibiotics are frequently used for community-acquired pneumonia (CAP), although viral etiologies predominate. We sought to determine factors associated with antibiotic use among children hospitalized with suspected CAP.

METHODS
We conducted a prospective cohort study of children who presented to the emergency department (ED) and were hospitalized for suspected CAP. We estimated risk factors associated with receipt of ≥1 dose of inpatient antibiotics and a full treatment course using multivariable Poisson regression with an interaction term between chest radiograph (CXR) findings and ED antibiotic use. We performed a subgroup analysis of children with nonradiographic CAP.

RESULTS
Among 477 children, 60% received inpatient antibiotics and 53% received a full course. Factors associated with inpatient antibiotics included antibiotic receipt in the ED (relative risk 4.33 [95% confidence interval, 2.63–7.13]), fever (1.66 [1.22–2.27]), and use of supplemental oxygen (1.29 [1.11–1.50]). Children with radiographic CAP and equivocal CXRs had an increased risk of inpatient antibiotics compared with those with normal CXRs, but the increased risk was modest when antibiotics were given in the ED. Factors associated with a full course were similar. Among patients with nonradiographic CAP, 29% received inpatient antibiotics, 21% received a full course, and ED antibiotics increased the risk of inpatient antibiotics.

CONCLUSIONS
Inpatient antibiotic utilization was associated with ED antibiotic decisions, CXR findings, and clinical factors. Nearly one-third of children with nonradiographic CAP received antibiotics, highlighting the need to reduce likely overuse. Antibiotic decisions in the ED were strongly associated with decisions in the inpatient setting, representing a modifiable target for future interventions.
Az evolúciós pszichológia paradigma újragondolása: A továbblépés irányai
Authors: Szabó Lajos , Bereczkei Tamás 
Published: July 2022

Az evolúciós pszichológia (EP) legnagyobb érdeme, hogy következetesen kifejtett formában mutatta be, hogy a darwini evolúcióelmélet alkalmas a pszichológiára mint tudományterületre vonatkozó metaelmélet szerepének betöltésére. Az irányzat által képviselt adaptácionista megközelítés mindmáig nagyszámú pszichológiai jelenségnek új szempontokon alapuló vizsgálatához és magyarázatához járult hozzá. Más tekintetben viszont az EP mint paradigma némileg egyoldalú maradt – ami részben a keletkezésének időszakában dominánsnak mutatkozó kognitív elméletek (így pl. Chomsky-féle innátista megközelítés, a Fodor képviselte modularizmus) feltételek nélküli elfogadására vezethető vissza. Az egyoldalúság kialakulásához az is hozzájárult, hogy az EP képviselői nem szenteltek kellő figyelmet a humángenetika, a fajok közötti összehasonlító pszichológia és a kulturális pszichológia terén zajló fejlődésnek. Az ebből adódó korlátokra és leegyszerűsítésekre az EP-vel szembeni kritikák már több alkalommal rámutattak. A kritika azonban önmagában nem jelent megújulást. Ebben a tanulmányban ezért az evolúciós pszichológiai megközelítés újraaktualizálásának lehetőségeit, a továbblépés irányait vesszük számba. A legújabb, a genetikai hatásokkal, az állati elme működésével vagy épp a pszichológiai különbségek kulturális hátterével kapcsolatos tudományos eredmények ugyanis lehetőséget kínálnak arra, hogy a Tinbergen négy kérdése által kijelölt területeken újragondoljuk és kiegészítsük az evolúciós pszichológia eredeti feltevéseit.
Review of the background to increased risks of SARS-CoV-2 pneumonia among elderly people
Authors: Losonczy GY. 
Published: July 2022

Abstract
Morbidity and mortality rates during the COVID-19 pandemic have been particularly high among elderly people (>65 years). This review summarises some of the important physiological and clinical aspects in the background of augmented risk. Airway clearance provides defence against inhaled particles, including viruses. Some relevant studies have indicated that clearance from the small and large airways is slower in elderly people. Cough peak flow (the speed of expiratory airflow during coughing, or cough power) is another important parameter that reflects the defence capacity of the respiratory system. Age has likewise been shown to induce inspiratory and expiratory muscle weakness and, as a consequence, a low cough peak flow. In addition to the weakening of these non-specific defences in elderly people, the specific immune response against the SARS-CoV-2 virus has been found to be nearly blocked in aged mice, and the augmented synthesis of prostaglandin D2 (PGD2) was found to play a role in this phenomenon. Aged animals were protected from death by a specific antagonist of PGD2. Among aged people suffering from COVID-19, there were disproportionally more patients with low CD8 T lymphocyte counts and high plasma concentrations of interleukin 6 (IL-6). This combination of deficient cellular immunity and overt inflammatory response in COVID-19 has been identified as a significant risk factor of mortality.
Quality of Life for People who Sing

Published: July 2022

Background: A growing ageing population in New Zealand and worldwide poses a number of challenges, including the predicted strain on public health services due to a consequential increase in neurological conditions, which tend to occur later in life. Diagnosis with a neurological condition is associated with negative psychosocial and quality of life (QOL) outcomes, which medical interventions do not address. There is growing interest in the role of music and singing in improving some of these negative outcomes that provides a rationale for the present research.
Methods: This mixed methods research explores the health-related quality of life (HRQOL) of 90 choir singers who sing in neurological choirs (social singing groups offering choral singing therapy) and community choirs in New Zealand. HRQOL data were obtained using the NZ WHOQOL-BREF and choir involvement perspectives were obtained using a choir participation questionnaire (CPQ). Non-parametric statistical tests were used to explore the NZ WHOQOL-BREF and visual analogue scale (VAS) responses in the CPQ. Qualitative measures were used to explore open-ended responses in the CPQ.
Results: HRQOL was similar across participants on the psychological, social relationships, and environmental domains, and lower for neurological choir members on the physical domain. Choir involvement perspectives showed that choir members perceived several positive benefits associated with choral singing that were often identified under the psychological, social relationships, and environmental domains.

A formação didática dos professores consiste em um importante campo de pesquisa científica e tecnológica. Na perspectiva da educação matemática há uma diversidade de pesquisas centradas na formação de professores de matemática. Este artigo consiste em um recorte de uma pesquisa de mestrado e tem por objetivo analisar o conhecimento didático-matemático mobilizado por futuros professores de matemática ao resolverem tarefas centradas em temas relacionados à educação financeira na perspectiva da educação matemática. Trata-se de uma pesquisa qualitativa desenvolvida no contexto da formação de professores de matemática por uma amostra constituída por estudantes da licenciatura em matemática de duas instituições públicas de ensino superior do Norte de Minas Gerais (Brasil). Para a coleta de dados, foi desenvolvido uma oficina com cinco tarefas, sendo quatro síncronas, realizadas pelo Google Meet e uma assíncrona, postadas no Google Classroom, que articulam conteúdos matemáticos com temáticas relacionadas à Educação Financeira, a saber: Reflexão sobre uma aula de Matemática; Refletindo sobre inflação e os índices de preços; Analisando o financiamento habitacional; Analisando juros e suas aplicações em operações de crédito; Elaborando atividades relacionadas às aplicações de juros. A análise de dados, realizada a partir das dimensões matemática e didática do modelo de Conhecimento Didático-Matemático (CDM), revelou que os futuros professores mobilizaram satisfatoriamente o conhecimento comum do conteúdo matemático, e parcialmente o conhecimento ampliado. Entretanto, a mobilização do conhecimento didático foi satisfatória apenas na faceta cognitiva e parcial nas demais facetas do CDM.

Authors: Kadu Rakesh K , Adane Dattatraya S 
Published: July 2022

This paper presents an area efficient and high-speed FPGA implementation of scalar multiplication using a Vedic multiplier. Scalar multiplication is the most important operation in Elliptic Curve Cryptography(ECC), which used for public key generation and the performance of ECC greatly depends on it. The scalar multiplication is multiplying integer k with scalar P to compute Q=kP, where k is private key and P is a base point on the Elliptic curve. The Scalar multiplication underlying finite field arithmetic operation i.e. addition multiplication, squaring and inversion to compute Q. From these finite field operations, multiplication is the most time-consuming operation, occupy more device space and it dominates the speed of Scalar multiplication. This paper presents an efficient implementation of finite field multiplication using a Vedic multiplier. The scalar multiplier is designed over Galois Binary field GF(2233) for field size=233-bit which is secured curve according to NIST. The performances of the proposed design are evaluated by comparing it with Karatsuba based scalar multiplier for area and delay. The results show that the proposed scalar multiplication using Vedic multiplier has consumed 22% less area on FPGA and also has 12% less delay, than Karatsuba, based scalar multiplier. The scalar multiplier is coded in Verilog HDL, synthesize and simulated in Xilinx 13.2 ISE on Virtex6 FPGA.

Published: July 2022

El presente estudio, de carácter descriptivo, partió del análisis practicado a una base de datos institucional que contenía las respuestas a una encuesta aplicada a egresados de programas de posgrados de una Institución de Educación Superior Pública. La muestra incluyó a egresados de posgrados profesionalizantes y de investigación, con el objetivo de identificar las competencias de investigación autoevaluadas por los mismos. Los resultados indicaron que un alto porcentaje de los entrevistados señaló haber mejorado sus competencias de investigación. No obstante, el hecho de que no es posible verificarlas in situ, deja como único recurso de verificación las calificaciones obtenidas durante su transcurso en el programa. Se requiere investigación que posibilite la constatación de la existencia de dichas competencias. Entre las recomendaciones derivadas del estudio se sugiere el diseño de un espacio formativo institucional sobre gestión de la investigación, de modo que impacte positivamente en la creación de espacios para esta práctica, a la vez que su promoción en el mercado laboral del egresado del posgrado.

Background and Purpose: Morphological features of one year old holm oak (Quercus ilex) seedlings grown in different types of containers were analyzed in order to establish the effect of container type on seedlings’ development. The survival rates and the development of the seedlings were measured and monitored in the period of six years, on an experimental plot with the aim to assess the influence of container size and soil preparation on afforestation success in Mediterranean karst area. Materials and Methods: Four types of containers were used: MP53/12, MP33/18, T7/24 and T8/24. Morphological features of seedlings include: height, root collar diameter, biomass of the aboveground part, root biomass and total biomass. Two morphological indexes were calculated from the measured variables: S:R ratio and DQI. Morphological dimensions of root systems are, namely: total length, the number of tips, surface area and volume. Seedlings were arranged over the area of the experimental plot according to the randomized block method. Within each block (0,2 ha) two types of soil preparation prior to planting were performed: in pits with dimensions of 40 × 40 × 40 cm, and on the ripping ground. Each year during the experiment, seedlings were measured for height increment and survival rates (e.g. mortality), with respect to the container type and the planting method. Results: Almost all morphological features of seedlings have significantly higher values in larger containers (T7/24 and T8/24) compared to smaller containers (MP53/12 and MP33/18). Survival rates over six years in field experiment are influenced mainly by container size in interaction with soil preparation method (exp (β) = 6.5789; p < 0.0001). The container size exhibited influence on height increment of holm oak during first six years (F = 20.619, p = 0.000012). Conclusions: Soil preparation by ripping combined with high-quality seedlings played the most important role in the holm oak’s survival in the research area. Key words: Mediterranean karst area, container type, morphological features of seedlings, soil preparation, afforestation success, height increment
