Authors: Liu Man , Han Guilin , Li Xiaoqiang , Zhang Shitong , Zhou Wenxiang , Zhang Qian
Published: January 2020

Soil erosion has become a serious ecological problem in many catchments. Soil erodibility K factor can be estimated based on a series of soil properties, however, the identification of dominant soil properties that affect K factor prediction at different soil types has been little concerned. In this study, 3 soil profiles from the Jiulongjiang River Catchment (JRC) of granite region in Fujian province and 18 soil profiles from the Chenqi Catchment (CC) of karst region in Guizhou province were selected. Soil properties, including soil particle size distribution, soil organic carbon (SOC) and soil organic nitrogen (SON) content, and soil pH, were determined, and the K factors were estimated in the erosion productivity impact calculator (EPIC) model. The soils in the granite region were characteristic for coarse texture, low SOC and SON, and strong acidity compared with limestone soils. Although the K factors in both regions ranged from 0.009 to 0.018, they were overestimated in limestone soils due to frequent soil aggregation, which enhanced soil permeability, hence reduced soil erodibility. The results of principal component analysis (PCA) and structural equation model (SEM) showed that (1) K factor estimation in the soils of the granite region mainly depended on soil texture, of which silt was the most important factor; (2) while K factor in limestone soils was mainly controlled by soil organic matter (SOM) content, other soil properties, including soil pH, clay and silt contents, could indirectly affect prediction of K factor by affecting SOM accumulation.

Published: January 2020

The low power generation efficiency of microbial fuel cells (MFCs) is always a barrier to further development. An attempt to enhance the start-up and electricity generation of MFCs was investigated by adding different doses of zero-valent iron into anaerobic anode chambers in this study. The results showed that the voltage (289.6 mV) of A2 with 0.5 g of zero-valent iron added was higher than the reference reactor (197.1 mV) without dosing zero-valent iron (A4). The maximum power density of 27.3 mW/m2 was obtained in A2. CV analysis demonstrated that A2 possessed a higher oxidation–reduction potential, hence showing a stronger oxidizing property. Meanwhile, electrochemical impedance analysis (EIS) also manifested that values of RCT of carbon felts with zero-valent iron supplemented (0.01–0.03 Ω) were generally lower. What is more, SEM images further proved and illustrated that A2 had compact and dense meshes with a hierarchical structure rather than a relatively looser biofilm in the other reactors. High-throughput sequencing analysis also indicated that zero-valent iron increased the abundance of some functional microbial communities, such as Acinetobacter, Ignavibacteriales, Shewanella, etc.

Published: January 2020

Osteoporosis (OP) is a systemic disease of the skeleton characterized by increased risk of fracture. There is a general consensus on the efficacy of physical activity in the prevention of bone loss, falls and fractures, but there is no agreement on the best setting to exercise. The aim of the study is to evaluate the efficacy of a 12-months exercise protocol for women with post-menopausal OP when administered as individual home training (IHT) versus gym group training (GGT). The study is a randomized trial with two parallel groups. Sedentary patients with primary post-menopausal osteoporosis are recruited at the Istituto Ortopedico Rizzoli of Bologna. In the first group, the 12-month ACTLIFE program is performed as IHT, while in the second as GGT. The program is aimed at improving joint mobility, muscle force, balance, motor coordination and endurance. The study is single blinded. Patients are assessed at baseline and after 6 and 12 months. The primary outcome is the modification of quality of life measured with the Short Osteoporosis Quality of Life Questionnaire (ECOS-16). The findings of this study will highlight advantages and disadvantages of exercising in the two different settings and provide evidence on how to increase physical activity in osteoporotic women.

Published: January 2020

Belt positioning boosters reduce injury risk for child occupants compared with seat belts alone. While boosters shorten the effective seat length (and thus reduce slouching), “boosting” the child relative to the vehicle interior components also achieves additional safety benefits. First, the increase of the lap belt angle usually improves belt fit across the pelvis and reduces the risk of the occupant slipping (“submarining”) under the belt. Second, the torso belt is re-centered over the bony landmarks of the shoulder for more effective/secure restraint. Third, the child’s head is relocated in a range better protected by side airbags. The objective of this research was to quantify differences in posture and belt fit across a range of booster designs that provide different levels of boosting. Posture and belt fit were measured in 25 child volunteers aged four to 12. Children were measured in three laboratory seating conditions selected to provide a range of cushion lengths and belt geometries. Six different boosters, as well as a no-booster condition, were evaluated. The low height boosters produced postures that were more slouched, with the hips further forward than in other more typical boosters. Lap belt fit in the low height boosters was not meaningfully different from the other boosters. Shoulder belt fit produced by the lowest height booster was similar to the no-booster condition. Belt positioning boosters that boost the child less than 70 mm produced postures similar to the no-booster condition. While lap belt guides on these products can produce a similar static lap belt fit, they may not provide adequate dynamic performance and do not achieve the other benefits that come with raising the child to a more advantageous location relative to interior components and belts.
Targeting the Immune system and Epigenetic Landscape of Urological Tumors
Authors: Lobo João , Jerónimo Carmen , Henrique Rui
Published: January 2020

In the last years, we have witnessed remarkable advances in targeted therapies for cancer patients. There is a growing effort to either replace or reduce the dose of unspecific, systemic (chemo)therapies, given the associated short- and long-term side effects, by introducing more specific targeted therapies as single or combination agents. Due to the well-known implications of the immune system and epigenetic landscape in modulating cancer development, both have been explored as potential targets in several malignancies, including those affecting the genitourinary tract. As the immune system function is also epigenetically regulated, there is rationale for combining both strategies. However, this is still rather underexplored, namely in urological tumors. We aim to briefly review the use of immune therapies in prostate, kidney, bladder, and testicular cancer, and further describe studies providing supporting evidence on their combination with epigenetic-based therapies.

Authors: Lopresti Mattia , Alberto Gabriele , Cantamessa Simone , Cantino Giorgio , Conterosito Eleonora , Palin Luca , Milanesio Marco
Published: January 2020

Composite lightweight materials for X-ray shielding applications were studied and developed with the goal of replacing traditional screens made of lead and steel, with innovative materials with similar shielding properties, but lighter, more easily formed and workable, with lower impact on the environment and reduced toxicity for human health. New epoxy based composites additivated with barium sulfate and bismuth oxide were designed through simulations performed with softwares based on Geant4. Then, they were prepared and characterized using different techniques starting from digital radiography in order to test the radiopacity of the composites, in comparison with traditional materials. The lower environmental impact and toxicity of these innovative screens were quantified by Life Cycle Assessment (LCA) calculation based on the ecoinvent database, within the openLCA framework. Optimized mixtures are (i) 20% epoxy/60% bismuth oxide/20% barite, which guarantees the best performance in X-ray shielding, largely overcoming steel, but higher in costs and a weight reduction of circa 60%; (ii) 20% epoxy/40% bismuth oxide/40% barite which has slightly lower performances in shielding, but it is lighter and cheaper than the first one and (iii) the 20% epoxy/20% bismuth oxide/60% barite which is the cheapest material, still maintaining the X-ray shielding of steel. Depending on cost/efficiency request of the specific application (industrial radiography, aerospace, medical analysis), the final user can choose among the proposed solutions.
Mass Spectrometry-Based Multivariate Proteomic Tests for Prediction of Outcomes on Immune Checkpoint Blockade Therapy: The Modern Analytical Approach
Authors: Grigorieva Julia , Asmellash Senait , Net Lelia , Tsypin Maxim , Roder Heinrich , Roder Joanna
Published: January 2020

The remarkable success of immune checkpoint inhibitors (ICIs) has given hope of cure for some patients with advanced cancer; however, the fraction of responding patients is 15–35%, depending on tumor type, and the proportion of durable responses is even smaller. Identification of biomarkers with strong predictive potential remains a priority. Until now most of the efforts were focused on biomarkers associated with the assumed mechanism of action of ICIs, such as levels of expression of programmed death-ligand 1 (PD-L1) and mutation load in tumor tissue, as a proxy of immunogenicity; however, their performance is unsatisfactory. Several assays designed to capture the complexity of the disease by measuring the immune response in tumor microenvironment show promise but still need validation in independent studies. The circulating proteome contains an additional layer of information characterizing tumor–host interactions that can be integrated into multivariate tests using modern machine learning techniques. Here we describe several validated serum-based proteomic tests and their utility in the context of ICIs. We discuss test performances, demonstrate their independence from currently used biomarkers, and discuss various aspects of associated biological mechanisms. We propose that serum-based multivariate proteomic tests add a missing piece to the puzzle of predicting benefit from ICIs.

Published: January 2020

Vaginal mesh erosion is a devastating complication after pelvic floor mesh surgery and it can be treated conservatively or with surgical revision. However, the management options following a failed primary revision or complex vaginal erosions are very limited. The aim of this study is to describe a novel treatment using an amniotic membrane as an inlay graft for such patients. Eight patients who failed conservative or primary surgical revision were enrolled. The complex erosions included vaginal agglutination, multiple vaginal erosions, recurrent erosions, and mesh cutting through the urethra. We used an amniotic membrane as a graft to cover the vaginal defect after partial excision of the mesh erosion and we describe the technique in this study. There were no intraoperative complications and none of the patients reported any further symptoms at a mean of 27 months follow-up. Only one patient had recurrent erosion, however, the erosion size was narrower and was subsequently successfully repaired. No further vaginal mesh erosions were noted in the other patients who all had good functional recovery. The use of an amniotic graft can be an economic and alternative method in the management of complex vaginal mesh erosions.

A Facile and Green Synthesis of a MoO2-Reduced Graphene Oxide Aerogel for Energy Storage Devices
Authors: Serrapede Mara , Fontana Marco , Gigot Arnaud , Armandi Marco , Biasotto Glenda , Tresso Elena , Rivolo Paola
Published: January 2020

A simple, low cost, and “green” method of hydrothermal synthesis, based on the addition of l-ascorbic acid (l-AA) as a reducing agent, is presented in order to obtain reduced graphene oxide (rGO) and hybrid rGO-MoO2 aerogels for the fabrication of supercapacitors. The resulting high degree of chemical reduction of graphene oxide (GO), confirmed by X-Ray Photoelectron Spectroscopy (XPS) analysis, is shown to produce a better electrical double layer (EDL) capacitance, as shown by cyclic voltammetric (CV) measurements. Moreover, a good reduction yield of the carbonaceous 3D-scaffold seems to be achievable even when the precursor of molybdenum oxide is added to the pristine slurry in order to get the hybrid rGO-MoO2 compound. The pseudocapacitance contribution from the resulting embedded MoO2 microstructures, was then studied by means of CV and electrochemical impedance spectroscopy (EIS). The oxidation state of the molybdenum in the MoO2 particles embedded in the rGO aerogel was deeply studied by means of XPS analysis and valuable information on the electrochemical behavior, according to the involved redox reactions, was obtained. Finally, the increased stability of the aerogels prepared with l-AA, after charge-discharge cycling, was demonstrated and confirmed by means of Field Emission Scanning Electron Microscopy (FESEM) characterization.

Published: January 2020

PEGylated nanomedicines are known to induce infusion reactions (IRs) that in some cases can be life-threatening. Herein, we report a case study in which a patient with rare mediastinal and intracardiac IgG4-related sclerosing disease received 8 treatments of intravenously administered PEGylated liposomal methylprednisolone-succinate (NSSL-MPS). Due to the ethical requirements to reduce IRs, the patient received a cocktail of premedication including low dose of steroids, acetaminophen and H2 blockers before each infusion. The treatment was well-tolerated in that IRs, complement activation, anti-PEG antibodies and accelerated blood clearance of the PEGylated drug were not detected. Prior to the clinical study, an in vitro panel of assays utilizing blood of healthy donors was used to determine the potential of a PEGylated drug to activate complement system, elicit pro-inflammatory cytokines, damage erythrocytes and affect various components of the blood coagulation system. The overall findings of the in vitro panel were negative and correlated with the results observed in the clinical phase.
Antibacterial Peptide Nucleic Acids—Facts and Perspectives
Authors: Wojciechowska Monika , Równicki Marcin , Mieczkowski Adam , Miszkiewicz Joanna , Trylska Joanna
Published: January 2020

Antibiotic resistance is an escalating, worldwide problem. Due to excessive use of antibiotics, multidrug-resistant bacteria have become a serious threat and a major global healthcare problem of the 21st century. This fact creates an urgent need for new and effective antimicrobials. The common strategies for antibiotic discovery are based on either modifying existing antibiotics or screening compound libraries, but these strategies have not been successful in recent decades. An alternative approach could be to use gene-specific oligonucleotides, such as peptide nucleic acid (PNA) oligomers, that can specifically target any single pathogen. This approach broadens the range of potential targets to any gene with a known sequence in any bacterium, and could significantly reduce the time required to discover new antimicrobials or their redesign, if resistance arises. We review the potential of PNA as an antibacterial molecule. First, we describe the physicochemical properties of PNA and modifications of the PNA backbone and nucleobases. Second, we review the carriers used to transport PNA to bacterial cells. Furthermore, we discuss the PNA targets in antibacterial studies focusing on antisense PNA targeting bacterial mRNA and rRNA.
Exploration of Mechanochemical Activation in Solid-State Fluoro-Grignard Reactions
Authors: Speight Isaiah R. , Hanusa Timothy P.
Published: January 2020

Owing to the strength of the C–F bond, the ‘direct’ preparation of Grignard reagents, i.e., the interaction of elemental magnesium with an organic halide, typically in an ethereal solvent, fails for bulk magnesium and organofluorine compounds. Previously described mechanochemical methods for preparing Grignard reagents have involved ball milling powdered magnesium with organochlorines or bromines. Activation of the C–F bond through a similar route is also possible, however. For example, milling 1- and 2-fluoronaphthalene with an excess of magnesium metal for 2 h, followed by treatment with FeCl3 and additional milling, produces the corresponding binaphthalenes, albeit in low yields (ca. 20%). The yields are independent of the particular isomer involved and are also comparable to the yields from corresponding the bromonaphthalenes. These results may reflect similar charges that reside on the α-carbon in the naphthalenes, as indicated by density functional theory calculations.
Time in the Upaniṣads
Authors: Cohen Signe
Published: January 2020

The Upaniṣads (ca. 800 BCE) were composed during a transitional time period in Hinduism when Vedic ritual and cosmogonic ideas began to give way to new worldviews. The intriguing Upaniṣadic notions of time have received little attention in the scholarly literature compared to the elaborate models of cyclical time that develop in later texts. I propose, however, that the Upaniṣads represent a seminal reorientation in Hindu conceptions of time. We still find an older view of time in the Upaniṣads as something that marks the rhythms of the ritual year, but later Upaniṣadic texts begin to explore entirely new ways of thinking about time. I propose that the movement away from the more integrated view of the material and immaterial as one reality in the Vedas towards a radical dualism between the spiritual and the material in later Hindu thought informs many of the new ideas of time that emerge in the Upaniṣads, including that of time as an abstract construct. The authors of the Upaniṣads investigate—and ultimately reject—the notion of time itself as the cause of the visible world, ponder the idea that time is something that is created by a divine being in order to structure the world, speculate that time may be a mere intellectual construct, and postulate that the highest reality may be situated in a realm that is outside of time altogether.
A Low-Cost IEEE 802.15.7 Communication System Based on Organic Photodetection for Device-to-Device Connections
Authors: Corral Pablo , Rodríguez-Mas Fernando , Alonso José Luis , Ferrer Juan Carlos , Fernández de Ávila Susana
Published: January 2020

In this article, we compare two different kinds of commercial light-emitting diodes (LEDs) in transmission and organic photodetectors based on poly(3-hexylthiophene) (P3HT) and a phenyl-C61-butyric acid methyl ester (PCBM) blend used as active layer in reception. Photovoltaic cells based on massive heterojunctions of semiconductor polymers have focused the attention of researchers due to their several potential advantages over their inorganic counterparts, such as their simplicity, low cost, and ability to process large area devices, even on flexible substrates. Furthermore, in logistics, storage management systems require the implementation of technological solutions that allow the control of merchandise in real time by means of light-emitting diode signals that send information about the product. However, the slow response time of these organic photodetectors should not be critical for this application, where the light intensity changes are very slow, which limits the speed of data transmission compared to inorganic based systems that use wireless optical communications. Finally, we show a low-cost visible light communication system based on organic photodetectors with a frame based on on-off keying with Manchester encoding to support device-to-device connections.
A LiDAR Point Cloud Data-Based Method for Evaluating Strain on a Curved Steel Plate Subjected to Lateral Pressure
Authors: Jo Hyeon Cheol , Sohn Hong-Gyoo , Lim Yun Mook
Published: January 2020

Structural health monitoring (SHM) and safety assessment are very important areas for evaluating the behavior of structures. Various wired and wireless sensors can measure the physical responses of structures, such as displacement or strain. One recently developed wireless technique is a light imaging detection and ranging (LiDAR) system that can remotely acquire three-dimensional (3D) high-precision coordinate information using 3D laser scanning. LiDAR systems have been previously used in geographic information systems (GIS) to collect information on geography and terrain. Recently, however, LiDAR is used in the SHM field to analyze structural behavior, as it can remotely detect the surface and deformation shape of structures without the need for attached sensors. This study demonstrates a strain evaluation method using a LiDAR system in order to analyze the behavior of steel structures. To evaluate the strains of structures from the initial and deformed shape, a combination of distributed 3D point cloud data and finite element methods (FEM) was used. The distributed 3D point cloud data were reconstructed into a 3D mesh model, and strains were calculated using the FEM. By using the proposed method, the strain could be calculated at any point on a structure for SHM and safety assessment during construction.
Changes in the presenting symptoms of lung cancer from 2000–2017: a serial cross-sectional study of observational records in UK primary care
Authors: Chowienczyk Sarah , Price Sarah , Hamilton Willie
Published: January 2020

Background

Most patients diagnosed with lung cancer present with symptoms. It is not known if the proportions of patients presenting with each symptom has changed over time. Identifying trends in lung cancer’s presenting symptoms is important for medical education and early-diagnosis initiatives.

Aim

To identify the first reported symptom of possible lung cancer (index symptom), and to test whether the percentages of patients with each index symptom changed during 2000–2017.

Design and setting

This was a serial, cross-sectional, observational study using UK Clinical Practice Research Datalink (CPRD) data with cancer registry linkage.

Method

The index symptom was identified for patients with an incident diagnosis of lung cancer in annual cohorts between 1 January 2000 and 31 December 2017. Searches were constrained to symptoms in National Institute for Health and Care Excellence (NICE) suspected-cancer referral guidelines, and to the year before diagnosis. Generalised linear models (with a binomial function) were used to test if the percentages of patients with each index symptom varied during 2000–2017.

Results

The percentage of patients with an index symptom of cough (odds ratio [OR] 1.01; 95% confidence interval [CI] = 1.00 to 1.02 per year; P<0.0001) or dyspnoea (OR 1.05; CI = 1.05 to 1.06 per year; P<0.0001) increased. The percentages of patients with other index symptoms decreased, notably haemoptysis (OR 0.93; CI = 0.92 to 0.95; P<0.0001) and appetite loss (OR 0.94; CI = 0.90 to 0.97; P<0.0001).

Conclusion

During 2000–2017, the proportions of lung cancer patients with an index symptom of cough or dyspnoea increased, while the proportion of those with the index symptom haemoptysis decreased. This trend has implications for medical education and symptom awareness campaigns.
The history of the future closure of Brygidki: 150 years of discussion to move the penitentiary outside of Lviv
Authors: Ackermann F.
Published: January 2020

This text will go back to the 19th century in order to show that the discussion about moving Brygidki to another location started as early as the 1870s when it turned out that the very materiality of the former convent prevented the legal bodies from adapting it to allow for a more dignified method of incarceration. In the 21st century, we witness an ongoing discussion on the need to move the Brygidki prison for people awaiting trial, officially Penal Institution No. 19, out of the city of Lviv.

Published: January 2020

У статті розглядаються особливості формування толерантного ставлення до інших релігій у колективній правосвідомості титульної більшості населення античного Риму. Відстоюється позиція, що релігійна толерантність була притаманна загальним поглядам та культурі римської полісної громади, що відобразилось у її правовій системі та позитивно вплинуло на розширення кордонів держави, налагодження взаємин з населенням приєднаних територій через гарантування їм свободи віросповідання, зниженням соціального напруження у суспільстві тощо. В подальшому через рецепцію римського права ця особливість правосвідомості буде закладена у підвалини західної традиції права, а в модерний період вплине на формування комплексу невід’ємних прав людини.

Lo bello bueno. Apuntes sobre la estetización de lo político en la Argentina kirchnerista.
Authors: Rolandelli Andrés
Published: January 2020

El objeto del siguiente trabajo es analizar el vínculo entre el fenómeno político y las ponderaciones provenientes de la estética, a la luz de lo que fue el período kirchnerista (2003-2015). El juicio estético tuvo un lugar destacado que potenció el carácter dual y conflictivo que supone la dimensión política para el populismo. El artículo analiza cómo la élite artística e intelectual argentina ofició de apologista y detractora de este período histórico. El trabajo intenta explorar como el juicio estético potenció al juicio moral en lo que hace a la caracterización del kirchnerismo y arriesga, a modo de hipótesis, la desactivación que de este binomio pretende la nueva coalición de gobierno como fórmula retórico política para construir su nuevo esquema de legitimación.
La definición de ‘populismo’: ¿qué puede aportar la semiótica?

Published: January 2020

Objetivo: Descrever reabilitações com coroas biológicas por meio de dois casos clínicos, um dente anterior e um posterior. Material e Método: O estudo apresenta dois casos clínicos em que reabilitações de dentes extensamente destruídos foram realizadas. Em um dos casos é apresentada a reabilitação do dente 14 e no seguinte uma reabilitação simultânea dos dentes 21 e 22. Em ambos os casos foram utilizados dentes humanos provenientes de um banco de dentes humanos (BDH). Para a seleção dos dentes, utilizou-se como parâmetros os diâmetros dos dentes a serem reabilitados, bem como as medidas do dente homólogo contralateral. Os dentes obtidos junto a BDH foram seccionados, a coroa biológica esvaziada e então reembasada com resina composta sobre um modelo de gesso obtido dos pacientes. Após o reembasamento e ajustes oclusais ainda no modelo de gesso, as coroas foram cimentadas com cimento resinoso. Resultados: Em ambos os casos clínicos, os pacientes foram reabilitados adequadamente, de forma rápida e com custo reduzido. Conclusão: Restaurações biológicas podem ser utilizadas para reabilitação de dentes permanentes anteriores e posteriores; além de estimular o correto descarte de futuros dentes extraídos, sendo esses destinados a bancos de dentes humanos.

Published: January 2020

Introdução: os traumatismos dentários são muito frequentes e estão entre os principais problemas de saúde pública. As fraturas radiculares tem uma ocorrência que varia entre 0,5 a 7% e acometem principalmente os incisivos superiores de crianças e adultos jovens. Portanto, necessitam de um diagnóstico preciso para que seja realizado um plano de tratamento e acompanhamento adequado. Objetivo: O presente estudo tem como objetivo relatar o caso clínico de fratura radicular em terço médio de um dente anterior, que foi tratado de forma conservadora e acompanhado por 30 meses. Relato de caso: O paciente gênero masculino, 42 anos, que procurou atendimento odontológico 23 dias após ter sofrido uma agressão física acometendo a face e o incisivo central superior. Ao exame clínico, observou-se uma discreta extrusão do 21 e ao exame radiográfico periapical detectou-se uma fratura horizontal no terço médio da raiz do mesmo dente. Foi realizada uma contenção semirrígida e desgaste incisal do 21. Após 45 dias, a contenção foi removida e o paciente orientado a retornar periodicamente para controle clínico e radiográfico. Após 30 meses de proservação, verifica-se ausência de dor e de mobilidade, resposta positiva aos testes térmicos de sensibilidade pulpar e cicatrização da linha de fratura ao exame radiográfico e tomográfico. Conclusões: Após este período de acompanhamento, pode-se concluir que o tratamento conservador proposto foi efetivo na manutenção do dente traumatizado, uma vez que este apresenta-se vital e desempenhando suas funções fisiológicas e estéticas

Objetivo: Avaliar o conhecimento de professores do ensino fundamental sobre as condutas nos casos de injúrias dentárias traumáticas (IDTs) em escolares. Material e método: O estudo foi realizado em uma amostra de 172 professores do ensino fundamental em João Pessoa-PB, e que responderam a um questionário com perguntas sobre os conhecimentos a cerca das condutas relacionadas ao tratamento emergencial de IDTs. Resultados: Os participantes do estudo eram em sua grande maioria do gênero feminino (79,6%) e tinham entre 20 e 40 anos (49,4%). Sobre os procedimentos a tomar após um acidente com trauma da face, 78% disseram que examinariam a boca das crianças. Com relação a possibilidade de salvar um dente fraturado, 78,5% dos entrevistados responderam positivamente. Em casos de dentes avulsionados, verificou-se que 7,6% dos professores não se preocupariam com o dente, apenas com a criança, e somente 33,7% procurariam o dente. O tempo ideal para procurar o cirurgião-dentista foi relatado por 52,8% como sendo no máximo 30 minutos. Quanto ao meio de armazenamento, 8,1% transportariam o dente imerso em leite e 29,7% em soro fisiológico. Conclusões: O nível de conhecimento dos professores foi insuficiente frente ao atendimento de urgência de traumatismos dentários, necessitando-se de capacitação com o intuito de minimizar as perdas dentárias.
La formación de ciudadanía en México a través de las radios comunitarias. Caso: Radio Teocelo, Veracruz
Authors: Mendoza Madrigal Mónica
Published: January 2020

Esta investigación plantea cómo las audiencias han modificado su consumo de medios, transformando tal dinámica en un proceso que requiere de ciudadanos participativos, que acceden al espacio público a través de los medios de comunicación para formar parte de la toma de decisiones colectivas para coparticipar del ejercicio del poder. En tal sentido, por medio de este trabajo se plantea que otras formas posibles de comunicar permiten reconstruir el tejido social fracturado en los modelos de comunicación comercial y público, haciendo posible el fortalecimiento de la democracia de manera auténtica, a través de medios cuyos contenidos fortalezcan la identidad, los valores y la cultura de sus regiones, al tiempo que aportan información específica de interés para sus audiencias, atendiendo a un reclamo social en zonas o regiones en donde los públicos no forman parte de la segmentación que interesa a otros modelos de medios. Así es como las radios comunitarias surgen y tienen valor para sus comunidades, en un trabajo que debe estar garantizado por el Estado, pues es a él al que le corresponde garantizar su funcionamiento en forma democrática, brindando la pluralidad y el equilibrio necesarios para facilitar el acceso de las audiencias al espacio público a fin de intervenir en la discusión y toma de decisiones de competencia colectiva, mediante el ejercicio efectivo de ciudadanía.

Itinerari turistico culturali in Toscana
Authors: Azzari Margherita , Cassi Laura
Published: January 2020

Three examples of enhancement of local culture have been developed in areas of great interest for their historical traditions and specific territorial values, according to the perspective that cultural itineraries must assume a growing importance in the context of a tourism based on sustainability criteria. The growth of the tourism and leisure market provides an effective stimulus to the creation of proposals aimed at prospecting new itineraries and at easing the most consolidated flows, adding a vast tradition of landscape and cultural values in significant territorial patterns. This is desirable also in the perspective of growing synergies between economy and culture.
Da amministratore a manager
Authors: Cavaliere Vincenzo , Rosini Dario
Published: January 2020

The public sector is changing under the pressure of increased competition, reduced resources and citizens' awareness about their role as customers/users. There is therefore a need for new principles and new tools for public management. However, such managerial skills do not belong to the political sphere and these new tools cannot be imported from the private sector without undergoing a specific adaptation. Public managers therefore play a central role in this process of change: in fact, the aim to be pursued is essentially to have more results-oriented attitudes on their part, in order to make a better use of the available resources.
La casa come "bene di consumo" nelle operazioni immobiliari di Francesco Sassetti
Authors: Rovida Maria Antonietta
Published: January 2020

Nell'Italia del Rinascimento, a partire soprattutto da Firenze, si diffondono l'interesse per l'architettura ad uso privato e un'attenzione alla qualità della vita anche in termini di spazi e arredi. La casa, dunque, viene ad essere un 'bene di consumo', sia nelle sue componenti edilizie, sia per quelle inerenti l'organizzazione distributiva e l'allestimento degli interni. Il tema viene preso in considerazione attraverso l'analisi di una serie di documenti di archivio che riguardano la residenza urbana di Francesco Sassetti a Firenze nella seconda metà del Quattrocento.
Città e stazione ferroviaria
Authors: Ventura Paolo
Published: January 2020

The text is the result of research and didactic activities in the context of urban planning courses held by the author at the university of Florence. It is to be considered as an aid in the study of urban phenomena, as a research tool and as an opportunity to arouse interest in urban planning operators towards a global approach to the problems of urban design. The text, preceded by an introductory essay by Antonio Acuto, examines the historical aspects from the development of railways in the nineteenth century to the consequences of changes in the current territorial and urban structures and the more properly architectural and qualitative aspects, tracing a concise history of the architecture of stations and of the impact in terms of renewing the city's image. The contents investigate urban planning issues, analysing the urban design options currently adopted to reduce functional conflicts and to mutually enhance railway and city facilities.
Donne mancanti
Authors: Rondinone Antonella
Published: January 2020

India population has fewer women than men (the 2001 census recorded 93 women for every 100 men) and the number of "missing women" is estimated to be between 30 and 62 million. The volume explains this demographic gender imbalance by means of a geographical analysis that embraces social, cultural, religious and economic aspects. The convergence point of the variables that negatively influence the female sex ratio is the low social and cultural value enjoyed by women, which translates into such a discrimination (in the access to food resources, medical care, education and well-being) that it strongly affects the female mortality rate.
