Published: November 2019

La anemia ferropénica es un tipo de anemia ocasionada por un déficit de hierro. El hierro es importante para el transporte de oxígeno a través de la sangre y la eritropoyesis. La falta de este elemento puede deberse a una mala absorción a nivel gastrointestinal, una dieta pobre en hierro o una pérdida prolongada de sangre. El presente artículo se origina en una actividad llevada a cabo en el aula sobre la simulación y discusión de un escenario clínico hipotético de anemia ferropénica en una mujer premenopáusica. Así, se describe la enfermedad y su manifestación. Adicionalmente, se incluye una revisión actualizada de la literatura y la descripción de un caso clínico real. El objetivo principal de este artículo es proveer a los profesionales de la salud con un panorama actualizado acerca de la patología y opciones para llevar a cabo una sospecha clínica de pacientes en riesgo.
Legitimität und Legitimitätssicherung von Betriebs- und Personalrat in organisationalen Veränderungen – Eine qualitative Analyse
Authors: Faupel Stefanie , Süß Stefan , Wulf Ines Catharina
Published: November 2019

Die Anzahl organisationaler Veränderungen hat in den letzten Jahren erheblich zugenommen. Sie stellen die betriebliche Interessenvertretung vor neue Herausforderungen. An welchen organisationalen Veränderungen Interessenvertretungen beteiligt sind und wie sich dies auf die von Beschäftigten zugeschriebene Legitimität sowie Maßnahmen der Legitimitätssicherung auswirkt ist bislang jedoch unklar. Zur Reduzierung des Forschungsdefizits wurden 25 Interviews mit Betriebs- und Personalratsmitgliedern in verschiedenen organisationalen Veränderungen geführt und inhaltsanalytisch ausgewertet. Es zeigt sich, dass sich die Legitimitätswahrnehmung abhängig von der Phase der Veränderung und ihrer Reichweite unterscheidet. Insbesondere für die befragten Betriebsratsmitglieder spielt Legitimitätssicherung in Veränderungsprozessen bislang eine eher untergeordnete Rolle. Dennoch legen die vorliegenden Studienergebnisse den Befund nahe, dass Legitimität in Veränderungssituationen durch die Interessenvertretung beeinflussbar ist.
Das Stinnes-Legien-Abkommen: Vorbild für eine Erneuerung der Sozialpartnerschaft?
Authors: Lesch Hagen
Published: November 2019

Im Stinnes-Legien-Abkommen vom November 1918 erkannten die Arbeitgeber die Gewerkschaften erstmals offiziell als berufene Vertreter der Arbeitnehmer an. Grundlage dieses historischen Schulterschlusses war, dass die Sozialpartner gemeinsam danach strebten, eine freiheitliche Wirtschafts- und Gesellschaftsordnung zu schaffen. Dieser erste Versuch, eine Sozialpartnerschaft zu begründen, scheiterte zwar. Aber die Absicht des Abkommens, die Arbeitsbedingungen autonom zu regeln, setzte sich durch. Die Tarifautonomie konnte sich nach dem Zweiten Weltkrieg als Säule der Sozialen Marktwirtschaft etablieren, weil die Tarifparteien lernten, ihren Interessenausgleich ohne Rückgriff auf den Staat als Schiedsrichter herzustellen. Die sinkende Tarifbindung zeigt aber, dass die Tarifparteien heute vor dem Problem stehen, Tarifaußenseiter vom Ergebnis ihres Interessenausgleichs zu überzeugen. Bei der Diskussion darüber, wie dieses Manko zu beheben ist, wird auch eine aktivere Rolle des Staates erwogen. Eine Rückbesinnung auf das Stinnes-Legien-Abkommen würde aber erst einmal die Tarifparteien in die Pflicht nehmen. Das setzt allerdings voraus, dass beide Seiten ihr Heil nicht in wechselseitigen Bündnissen mit staatlichen Akteuren sehen.
To reconstruction of the river’s categories which formed sedimentary basins of Riphean basins in the region of the Eastern European platform and modern south Urals juncture
Authors: Maslov A. V.
Published: November 2019

Information on the distribution of trace and rare-earth elements in the bottom sediments of estuarine zones of various river categories (large rivers, rivers draining water collections, composed of sedimentary or magmatic and metamorphic rocks, etc.) of silt and pelitic dimensions can be considered as the data, reflecting characteristic features of the suspention, transported to marine basins from various catchment provinces. In certain situations, the composition of the surface bottom sediments of the marine basin is determined by the suspension composition of any large river flowing into it (the Caspian Sea and the Volga River, the Laptev Sea and the Lena River, etc.). The similarity and difference in the rare-earth elements (REE) systematics of bottom sediments of estuarine zones and suspended particulate matter of rivers of various categories is quite well expressed in the pair diagrams (La/ Yb)N–(Eu/Sm)N, (La/Yb)N–Th, etc. A comparison of the features of the distribution of REE and Th in the Riphean clay rocks of the Southern Urals and in bottom sediments of the estuaries of various categories of recent rivers has been performed. It has been concluded that clay rocks forming a typical Riphean section are formed due to the erosion of mainly or predominantly sedimentary and/or metasedimentary complexes that existed during the PreRiphean or the Riphean in the east part of the East European platform and have not survived to date.

Authors: Aditya Ronal Surya
Published: November 2019

Basic life support (basic life support) is an action when a patient is found to be suddenly immobile, unconscious, or not breathing, so check the patient's response. The purpose of this study was to determine the effectiveness of the lecture method and health coaching about BLS (Basic Life Support) in mosque youth. The research design is quasy-experiment. The population of this study was all male mosques in the year totaling 80 people. The sample in this study was simple random sampling. The research instrument used is the Heart-saver® observation sheet. The results showed differences in the results of Wilcoxon and Mann-Whitney analysis in the treatment and control groups. For the control group, the lecture produced Wilcoxon (p = 0.26) and Mann-Whitney significance (p = 0.32). Whereas in the treatment group that received Health coaching produced Wilcoxon significance (p = 0.001) and Mann-Whitney (p = 0,000). Conclusion: Health coaching is more effective than the lecture method. Suggestion: the next researcher will combine health coaching with other methods to be able to provide more effective knowledge and skills.

Published: November 2019

We report a case of a 30-year-old male presented with acute pancreatitis after a period of diclofenac (Voltaren®) use. Other causes of pancreatitis were ruled out by thorough history, physical examination, and investigations. The patient was admitted and treated conservatively for five days and made a full recovery after the diclofenac was discontinued. To our knowledge, and as reported previously, it appears that diclofenac happens to be the only logical cause for this event. However, further evidence and studies are required to prove the association versus causative relation between usage of diclofenac and pancreatic insult.
Growing tropical tree planting stock in root trainers: Cell volume, seedling density and growing media
Authors: Singh Sanjay , Nain N. P. S. , Tripathi S. P.
Published: November 2019

The influence of root trainer cell volume and seedling density, and composition of growing media was examined in relation to morphological, biomass and seedling quality parameters of four-month old planting stock of three tropical broadleaved tree species viz., Acacia catechu, Azadiractha indica and Pongamia pinnata. The study revealed that a cell volume of 90 cm3 was not sufficient for proper seedling growth of A. catechu and A. indica. However, clear-cut superiority of 300 cm3 cell volume was evident only in the case of A. indica. It appeared that root trainer pots of 150 cm3 cell volume were suitable for growth of planting stock of A. catechu and P. pinnata and 300 cm3 cell volume for A. indica. Significant differences in the growth of planting stocks were observed among growing media treatments. Overall the tree species exhibited fast growth and high biomass as well as favorable seeding quality in growing media containing 80% compost with either sand (A. catechu and A. indica) or soil (P. pinnata) than the other treatments having 50%, 60% or 100% compost.
Space Syntax's Relation to Seating Choices from an Evolutionary Approach
Authors: Keszei Barbara , Halász Bálint , Losonczi Anna , Dúll Andrea
Published: November 2019

Space syntax provides information on the probabilities of certain behaviour types (e.g., seating choice, movement) depending on the configuration of space. The evolutionary approach (e.g. Appleton’s prospect-refuge theory) in environmental psychology can help designers in creating spaces by providing a better understanding why certain parts of an open space or a building are avoided or occupied, why good "observation points" or "hiding places” are preferred. Our research aimed to explore how different space syntax variables predict specific behaviours – the seating choices of 216 participants – in a 3D virtual model of a lounge area and how the prospect-refuge theory relates to these predictions. The participants had to choose a seat in simulated spaces in two social situations, which differed in the degree of focused work and concentration: one of the situations implied seeing others and being seen, while the other highlighted focused work and hiding. The results show that there was a variation in the seating choices depending on the goal of the situation (user: trying to be seen or hiding). The expected significant correlations with the space syntax measurements were presented in the situations where being seen was the goal of the participants. However, in the situations where hiding was induced, our results need further clarification. Our future goal is to provide quantitative, evidence-based reflection on the prospect-refuge and space syntax theories, and to investigate the psychological factors (e.g., goal of the user) that need further consideration when applying these theories in the design practice.

Published: November 2019

Biodiesel was synthesized from oleic acid using Ni (II)-exchanged heteropolyacids immobilized on silica (Ni0.5H3SiW / SiO2 ) as a solid acid catalyst. Based on detailed analyses of FT-IR, XRD, TG and SEM, the structural, surface and thermal stability of Ni0.5H3SiW / SiO2 were investigated. Obtained results demonstrated that the Keggin structure was well in the immobilization process and possess a high thermal stability. Various esterification reaction conditions and reusability of catalyst were studied. High oleic acid conversion of 81.4 % was observed at a 1:22 mole ratio (oleic acid: methanol), 3 wt. % catalyst at 70 °C for 4 h. The Ni0.5H3SiW / SiO2 catalyst was reused for several times and presented relatively stable. More interestingly, the kinetic studies revealed the esterification process was compatible with the first order model, and a lower activation energy was obtained in this catalytic system.
A New Nodal Stress Recovery Technique in Finite Element Method Using Colliding Bodies Optimization Algorithm
Authors: Kaveh Ali , Seddighian Mohammad Reza
Published: November 2019

In Finite Element Method (FEM), the stress components are calculated within the elements firstly, and then these components are recovered to the nodes. For the recovery process, there are several well-known methods in which the increase of their accuracy imposes additional costs into the problem. In this paper, a new nodal stress recovery technique is proposed in which Colliding Bodies Optimization (CBO) Algorithm fits an appropriative function for nodal stress fields. The CBO employs this function to compute the stress components in the nodal coordinates. Therefore, a particular model to stress fields and its components will be available. It can be considered as a connection between analytical approaches and numerical methods, providing benefits of both categories. Finally, the accuracy, efficiency, and applicability of the new technique are investigated employing three diverse examples.

Published: November 2019

Although the risks of medication poisoning in children are often reported, there is a lack of studies addressing this issue. The majority of papers deal with a wide range of xenobiotics poisoning and, in particular, alcohol intoxications. All hospital admissions during three years were prospectively recorded. Patients younger than 19 years of age admitted for acute drug intoxications were further evaluated. A total of 15,069 children were admitted. Of them, 55 were hospitalized for acute medication poisoning. The condition was more common in girls (72.7 % vs. 27.3 %, p<0.01). Toddlers were the largest patient group (36.4 %). Non-steroidal anti-inflammatory drugs (NSAIDs) were the most frequently used agents, with ibuprofen being the leading drug (20 % of all cases). The route of intoxication was almost exclusively oral. Solid drug forms were involved in 40 (72.7 %) cases. There was one fatal accidental poisoning. The highest occurrence of accidental drug intoxications was in the age group from one to three years. Attempted suicides were most frequent among adolescents. We are currently actively dealing with the issue. The cohort has been expanded to include a period of ten years and is being analyzed.

The risk of development of metabolic syndrome can be increased by hypertriglyceridemia. A search for effective therapy is a subject of considerable attention. Therefore, our hypothesis is that the fish oil (containing polyunsaturated fatty acids; n-3 PUFA) in a combination with silymarin can more effectively protect against hypertriglyceridemia-induced metabolic disturbances. The study was conducted using a unique non-obese strain of rats with hereditary hypertriglyceridemia an accepted model of metabolic syndrome. Adult male rats were treated with n-3 PUFA (300 mg/kg/day) without or with 1 % micronized silymarin in a diet for 4 weeks. The treatment with the diet containing n-3 PUFA and silymarin significantly reduced concentrations of serum triglycerides (-45 %), total cholesterol (-18 %), non-esterified fatty acids (-33 %), and ectopic lipid accumulation in skeletal muscle (-35 %) compared to controls. In addition, an increase in Abcg5 and Abcg8 mRNA expression (as genes affecting lipid homeostasis) as well as in protein content of ABCG5 (+78 %) and ABCG8 (+232 %) transporters have been determined in the liver of treated rats. Our findings suggest that this combined diet could be used in the prevention of hypertriglyceridemia-induced metabolic disorders.

The aim of this study was to evaluate the association between OPRM1 and ABCB1 polymorphisms on pain relief with epidural sufentanil in 69 patients after rectosigma resection for cancer. The median number of injections (SD) 2.31 (1.36), IQR=1, required by 118AA subjects was significantly lower in comparison with 118AG group 5.25 (3.13), IQR=6.5, (χ2=9.75, p=0.001); correspondingly median drug consumption of 1.16 (0.79), IQR=1.083, defined daily doses (DDD) was significantly less in the 118AA group in comparison with 2.14 (1.17), IQR=2.23, DDD in 118AG subjects, (χ2=7.00, p=0.008). Opioid-induced adverse effects were observed in 15 % and 33 % of patients in 118AA and 118AG groups, respectively (χ2=8.16, p=0.004). The median number of injections (SD) required by women and men was 3.30 (2.16), IQR=2, and 2.80 (1.59), IQR=1, respectively (χ2=6.25, p=0.012). Opioid-induced adverse effects were observed in 26 % and 12 % of women and men, respectively (χ2=5.49, p=0.011). Heterozygotes of OPRM1 polymorphism and women were more difficult to treat subpopulations that required higher doses of rescue analgesic medication and suffered more adverse effects.

This pilot prospective study verified the hypothesis that use of computer-assisted therapeutic drug monitoring of aminoglycosides by pharmacists leads to better safety therapeutic outcomes and cost avoidance than only concentration measurement and dose adjustments based on a physician’s experience. Two groups of patients were enrolled according to the technique of monitoring. Patients (Group 1, n=52) underwent monitoring by a pharmacist using pharmacokinetic software. In a control group (Group 2, n=11), plasma levels were measured but not interpreted by the pharmacist, only by physicians. No statistically significant differences were found between the groups in factors influenced by therapy. However, the results are not statistically significant but a comparison of the groups showed a clear trend towards safety and cost avoidance, thus supporting therapeutic drug monitoring. Safety limits were achieved in 76 % and 63 % of cases in Groups 1 and 2, respectively. More patients achieved both concentrations (peak and trough) with falling eGFR in Group 1. In present pilot study, the pharmacist improved the care of patients on aminoglycoside therapy. A larger study is needed to demonstrate statistically significantly improved safety and cost avoidance of aminoglycoside therapy monitoring by the pharmacist using pharmacokinetic software.

Healing and Growth after Trauma in a Rural Australian Community-A Case Study
Authors: Connell Jennifer O
Published: November 2019

This community case study outlines the development of a small group trauma recovery program (Leading from within), after several suicides created widespread community trauma. My training and almost 30 years experience as a Clinical Social Worker and my personal experience of trauma provided the impetus for this program which developed 20 years ago. The theoretical underpinnings include behavioural, depth, positive and energy psychology, trauma theory and the neuroscience of stress and trauma, attachment theory, family theory, wilderness theory, mind/body medicine, human potential theory, metaphysics (the science of Mind to Matter) [1], psychosynthesis and epigenetics (including the predisposition to transgenerational trauma).
Some individual practitioners have also influenced the thinking behind the program development: Viktor Frankl, a Jewish Psychiatrist developed Logotherapy, lost family members, his thesis and all of his possessions during the holocaust and spent considerable time in Auschwitz [2]. He observed people in the camp and saw a demonstration of his theory. His observation was that those who made some meaning for themselves in the situation of utter privation were the ones who seemed to survive the best. He noticed, for example that people who gave their last piece of bread to help someone else seemed to do better than others, even those who seemed physically stronger.
Matter Dynamics in a Unitary Relativistic Quantum Theory
Authors: Stefanescu Eliade
Published: November 2019

We describe the matter dynamics as a positively defined density and show that, according to the general theory of relativity, such a distribution can be conceive only as of a fragment of matter with a finite mass equal to a mass , as a characteristic of the matter dynamics, – the matter quantization. The group velocities of the Fourier conjugate representations in the coordinate and momentum spaces describe the dynamics of a quantum particle in agreement with the Hamiltonian equations. Under the action of an external (non-gravitational) field, the acceleration of the quantum matter has two components: 1) A component perpendicular to the velocity, given by the relativistic mechanical component of the time dependent phase, and 2) A component given by the additional field terms of this phase. A free quantum particle is described by a non-dispersing wave function , contrary to the solution of the Schrödinger equation. A coherent electromagnetic field, in resonance with a system of active quantum particles in a Fabry-Perot cavity, has a wave vector approximately proportional to the metric elements, as the resonance frequency is approximately constant – a gravitational wave can be detected by the transmission characteristics of an active Fabry-Perot cavity. In a constant gravitational field, a quantum particle undertakes a velocity and an acceleration, which, at the boundary of a black hole are null – absorption and evaporation processes at the boundary of a black hole arise only by gravitational perturbations. Generally, a quantum particle is described by a time-space volume, called graviton, with a spin 2, and a distribution of a specific matter in this volume, with a half-integer spin for Fermions and an integer spin for Bosons. A graviton Lagrangian is obtained as a curvature integral on a graviton volume, and a Hamiltonian tensor is obtained for the gravitational coordinates and velocities.

Iris germanica L. is an ornamental and medicinal plant used since ancient times for their rhizomes, still utilized today to obtain orris butter highly valued in perfumery. Iris germanica presents special root adaptations, which confers certain tolerance to water and salt stress, making it a good option in the context of the current climate trend. Aim of this study was to prospect the potential for biofortification of rhizomes using commercial arbuscular mycorrhizae (AM) application in field conditions for six Iris germanica cultivars. Plants presented Paris-type AM colonization. Rhizome samples collected after nine months from treatment and maturated, presented FT-IR (fourier transform infrared spectroscopy) spectra variation between experimental variants. Presence of the main metabolites in rhizome could be confirmed based on literature. Screening focused on two rhizome quality markers: carbohydrates, which influence plant development, and fatty acids, which are extractable from rhizome. Results suggest potential to enhance their accumulation in certain cultivars, such as ‘Pinafore Pink’ following AM application.

The characterization of straw decomposition and the resulting carbon (C) and nitrogen (N) release is crucial for understanding the effects of different straw returning methods on the immobilization and cycling of soil organic carbon (SOC) and soil total nitrogen (STN). In 2017–2018, a field micro-plot experiment was carried out in northeastern China to investigate the effects of different straw returning approaches on straw decomposition, C release, N release, SOC, STN, and the soil C–N ratio. Six straw returning treatments were applied: straw mixed with soil (SM) and straw buried in the soil (SB) at soil depths of 10 (O), 30 (T), and 50 cm (F). The results indicate that the straw decomposition proportion (SD), C release, and N release in SM + O were higher than that in SM + T and SM + F. Moreover, SOC and STN concentrations and the soil C–N ratio were significantly enhanced by SM/B + O in the 0–20 cm soil layers, SM/B + T in the 20–30 cm soil layer, and SM/B + F in the 40–60 cm soil layers. In the 0–50 cm soil profile, the highest SOC stocks were obtained using SB + T. The STN stocks were also significantly affected by the straw returning depth, but the effect was inconsistent between the two years. SD had a positive relationship with SOC and STN in the 0–20 cm soil layers; conversely, they were negatively related in the 30–60 cm soil layers. The results of this study suggest that straw buried in the soil to a depth not exceeding 30 cm might be an optimal straw returning approach in northeastern China.

Eight quinoline-based hydroxyimidazolium hybrids 7a–h were prepared and evaluated in vitro against a panel of clinically important fungal and bacterial pathogens, including mycobacteria. Hybrid compounds 7c–d showed remarkable antifungal activity against Cryptococcus neoformans with a minimum inhibitory concentration (MIC) value of 15.6 µg/mL. Against other opportunistic fungi such as Candida spp. and Aspergillus spp., these hybrids showed MIC values of 62.5 µg/mL. Regarding their antibacterial activity, all the synthetic hybrids demonstrated little inhibition of Gram-negative bacteria (MIC ≥50 µg/mL), however, hybrid 7b displayed >50% inhibition against Klebsiella pneumoniae at 20 µg/mL and full inhibition at 50 µg/mL. Moreover, this hybrid was shown to be a potent anti-staphylococcal molecule, with a MIC value of 2 µg/mL (5 µM). In addition, hybrid 7h also demonstrated inhibition of Staphylococcus aureus at 20 µg/mL (47 µM). Hybrids 7a and 7b were the most potent against Mycobacterium tuberculosis H37Rv with MIC values of 20 and 10 µg/mL (46 and 24 µM), respectively. The 7b hybrid demonstrated high selectivity in killing S. aureus and M. tuberculosis H37Rv in comparison with mammalian cells (SI >20), and thus it can be considered a hit molecule for mechanism of action studies and the exploration of related chemical space.

Authors: Rajauria Gaurav
Published: November 2019

Lipophilic compounds of seaweed have been linked to their potential bioactivity. Low polarity solvents such as chloroform, diethyl ether, n-hexane and their various combinations were used to extract the lipophilic antioxidants from brown seaweed namely Himanthalia elongata, Laminaria saccharina and Laminaria digitata. An equal-volume mixture of chloroform, diethyl ether and n-hexane (Mix 4) gave the highest total phenol (52.7 ± 1.93 to 180.2 ± 1.84 mg gallic acid equivalents/g), flavonoid (31.9 ± 2.65 to 131.3 ± 4.51 mg quercetin equivalents/g), carotenoid (2.19 ± 1.37 to 3.15 ± 0.91 μg/g) and chlorophyll content (2.88 ± 1.08 to 3.86 ± 1.22 μg/g) in the tested seaweeds. The extracts were screened for their potential antioxidant capacity and the extracts obtained from the selected solvents system exhibited the highest radical scavenging capacity against 2,2′-diphenly-1-picrylhydrazyl radical (EC50 98.3 ± 2.78 to 298.8 ± 5.81 mg/L) and metal ions (EC50 228.6 ± 3.51 to 532.4 ± 6.03 mg/L). Similarly, the same extract showed the highest ferric reducing antioxidant power (8.3 ± 0.23 to 26.3 ± 0.30 mg trolox equivalents/g) in all the seaweeds. Rapid characterization of the active extracts by liquid chromatography coupled with photodiode array detector and electrospray ionization tandem mass spectrometry (LC-PDA–ESI-MS/MS) identified cyanidin-3-O-glucoside, fucoxanthin, violaxanthin, β-carotene, chlorophyll a derivatives and chlorophyll b derivatives in the tested seaweed. The study demonstrated the use of tested brown seaweed as potential species to be considered for future applications in medicine, cosmetics and as nutritional food supplement.

Published: November 2019

The major cancer therapeutic modalities include surgery, chemotherapy and radiotherapy. Although these treatment regimens have played a significant role in effectively inhibiting cancer, their associated morbidity reduces the overall quality of life. Thus, researchers are striving to identify any alternate therapeutic approach capable of inhibiting cancer without eliciting the added morbidity. Among the alternate cancer therapeutics being researched, much importance is being given to the use of plants due to the presence of a wide variety of anti-carcinogenic compounds. Tinospora cordifolia (Tc) is one such plant and has shown to exhibit anti-carcinogenic properties. The present review aimed to systematically analyze published data on the effect of Tinospora cordifolia-derived phytocomponents on cancer. PubMed, Scopus, Web of Science, Embase and Cochrane library were searched using the keywords Tinospora cordifolia; anticancer; phytocomponents until March 20, 2019. In vivo and in vitro original studies in the English language were included. Of the 342 articles identified, only 25 articles met the selection criteria and were included in the review. Significant anti-carcinogenic properties were exhibited by Tinospora cordifolia-derived phytocompounds including palmative, berberine, new clerodane furanoditerene glycoside, arabinogalactan, phenolic compounds and epoxy cleodane diterpene. No significant side effects have been elicited with its use. Based on the data from the included studies, Tinospora cordifolia could be a natural therapeutic agent for cancer, provided its anti-carcinogenic properties can be elicited consistently at a large scale in clinical trials.
Sonic and Impact Test for Structural Assessment of Historical Masonry
Authors: Grazzini Alessandro
Published: November 2019

Diagnostics is a very important tool of knowledge in the field of historical buildings. In particular, non-destructive techniques allow to deepen the study of the mechanical characteristics of the historical walls without compromising the artistic value of the monumental building. A case study of the use of sonic and impact tests was described, performed using the same instrumented hammer, for the characterization of the masonry walls at the Sanctuary of Santa Maria delle Grazie at Varoni, one of the churches damaged in the 2016 Amatrice earthquake. Sonic tests showed the presence of a discontinous masonry texture, as well as confirming the ineffectiveness of the strengthening work made by injections of lime mortar. The impact test allowed us to obtain the elastic modulus of the omogeneous stones of the masonry. The results obtained from the non-destructive techniques were confirmed by the flat jacks test carried out on the building, confirming the great potential of the non-destructive diagnostics suitable for analyzing important structural parameters without affecting the preservation of historical masonry structures.

In this work, a thin film transistor (TFT) with Zr-doped aluminum-zinc-tin oxide (Zr-AZTO) semiconductor as active layer was investigated. The Zr-AZTO thin films were co-sputtered by ZrO2 and AZTO targets (RF-Sputter) in Ar, and annealed at 350 °C in air atmosphere. With the discharge power of AZTO increasing from 100 W to 120 W, the content of Zr element decreases from 0.63 ± 0.01 at.% to 0.34 ± 0.01 at.%, and the oxygen vacancy decreases from (19.0 ± 0.1)% to (17.3 ± 0.8)%. The results of Zr-AZTO thin film show that the main factor is the co-sputter power of ZrO2 target. With the co-sputter power of ZrO2 increasing from 15 W to 45 W, the content of Zr element increases from 0.63 ± 0.01 at.% to 2.79 ± 0.01 at.%, the content of oxygen vacancy decreases from (19.0 ± 0.1)% to (14.1 ± 0.1)%, Eg increases from 2.76 eV to 2.86 eV, and the root mean square (RMS) roughness firstly decreases from 0.402 nm to 0.387 nm and then increases to 0.490 nm. The Micro Wave Photo Conductivity Decay (μ-PCD, LTA-1620SP) was used to measure the quality of Zr-AZTO thin film and the mean peak and D value decreases from 139.3 mV to 80.9 mV and from 1.54 to 0.77 as the co-sputter power of ZrO2 increases from 15 W to 45 W, which means it has highest localized states and defects in high ZrO2 co-sputter power. The devices prepared at 15 W (ZrO2)/100 W (AZTO) co-sputter show a best performance, with a μsat of 8.0 ± 0.6 cm2/(V∙S), an Ion/Ioff of (2.01 ± 0.34) × 106, and a SS of 0.18 ± 0.03 V/dec. The device of Sample B has a 0.5 V negative shift under −20 V NBS and 9.6 V positive shift under 20 V PBS.
