Highly sensitive broadband photodetection is of critical importance for many applications. However, it is a great challenge to realize broadband photodetection by using a single device. Here we report photodetectors (PDs) based on three-dimensional (3D) graphene foam (GF) photodiodes with asymmetric electrodes, which show an ultra-broadband photoresponse from ultraviolet to microwave for wavelengths ranging from

, short response time of 43 ms, and 3 dB bandwidth of 80 Hz. The high performance of the devices can be attributed to the photothermoelectric (PTE, also known as the Seebeck) effect in 3D GF photodiodes. The excellent optical, thermal, and electrical properties of 3D GFs offer a superior basis for the fabrication of PTE-based PDs. This work paves the way to realize ultra-broadband and high-sensitivity PDs operated at room temperature.
A descriptive study of ciguatera fish poisoning in Cook Islands dogs and cats: Demographic, temporal, and spatial distribution of cases
Authors: Gray Michelle J.
Published: January 2020

Background and Aim: Ciguatera fish poisoning (CFP) is the most common form of seafood toxicosis reported in humans worldwide. Dogs and cats are also susceptible to CFP, but there is little published and much unknown about the condition in these species. This study aimed to document the demographics of canine and feline cases of CFP, to examine the temporal and spatial distribution of cases, and to compare the incidence of animal and human CFP in the Cook Islands.

Materials and Methods: Six years of medical records from the Esther Honey Foundation Animal Clinic (the only veterinary clinic in the Cook Islands during the study period) were reviewed to identify cases of CFP. The study variables included the date of presentation, species, age, sex, neutering status, and village/locality.

Results: A total of 246 cases of CFP were identified, comprising 165 dogs and 81 cats. The sexes were equally represented; however, within each sex, entire animals outnumbered those that had been desexed. Cases occurred year-round, with slightly higher numbers recorded in spring. Annual case numbers trended downward over the study period. Cases were documented in all regions of Rarotonga and also one outer island (Aitutaki). Fewer cases were seen in areas with a narrow (<200 m) fringing lagoon, compared with a wide (>400 m) lagoon.

Conclusion: This study documented epidemiologic patterns of canine and feline CFP cases for the first time. Based on the results, further investigation is warranted to establish whether desexing has a protective effect against CFP.
Creating the Jazz Solo
Authors: Hobson Vic
Published: January 2020

Throughout his life, Louis Armstrong tried to explain how singing on the streets of New Orleans with a barbershop quartet was foundational to his musicianship. However, up to now, there has been no in-depth inquiry into what he meant when he said “I Figure Singing and Playing is the Same, “or “Singing was more into my blood than the trumpet.” This book shows that Armstrong understood exactly the relationship between what he sang and what he played, and that he meant these comments to be taken literally: he was singing through his horn.
To describe the relationship between what Armstrong sang and played the book discusses elements of music theory. This is done in an approachable way for readers with little or no musical background. Jazz is a music that is often performed by people with a very limited musical education. Armstrong did not analyse what he played in theoretical terms, he thought about in terms of the voices in a barbershop quartet. This book describes Armstrong playing in term he would have understood.
Understanding how Armstrong, and other pioneer jazz musicians of his generation, learned to play jazz, and how he used this background of singing in a quartet to develop the jazz solo, has fundamental implications for the teaching of jazz performance today. This book provides a foundation for today’s musicians to learn to play jazz the Louis Armstrong way.

An objective process is needed in the selection of Bidikmisi Scholarship in UIN Sunan Kalijaga Yogyakarta, so the selected recipients are not misdirected and meet the established criteria. At present, the process is still manual so it requires a long time and triggers some errors. For this reason, a decision support system is needed to increase the efficiency and effectiveness of the ongoing selection process. The method used is Profile Matching. The method matches the profile of the new registrant with the ideal profile of the scholarship recipient. The matching results will provide recommendations for applicants who are eligible to award Bidikmisi Scholarships. There are 4 aspects used for calculations:  parents, students, house and the interview. From these aspects, it will be divided into 28 criteria with a range of criteria according to the predetermined criteria. System testing is done by Alpha and Beta testing, the results show that the system can function properly as expected. The system provides results as recommendations for candidates through ranking from the final results of system calculations.
RE-EVALUATION OF ANIMAL PROTECTION BY THE FINNISH ANIMAL RIGHTS LAWYERS SOCIETY
Authors: WAHLBERG BIRGITTA
Published: January 2020

The recognition of animals as sentient beings in the Treaty on the Functioning of the European Union (TFEU) gave rise to expectations as to real concern and care for animal welfare and a balance of human-animal interests. However, both the EU-legislation and the Finnish animal protection legislation is based on an animal welfare paradigm, meaning that animals have a weak legal status compared to humans that makes it impossible to de facto balance human and animal needs and interests in an effective manner from an animal point of view. The weak legal status of animals in the hierarchy of norms in the Finnish legal system contributes to the continuation of the oppression and exploitation of animals. The Finnish Animal Rights Lawyers Society have therefore made a proposal to strengthen animals’ legal status by including animals in the Finnish Constitution (FC) by safeguarding animals’ certain fundamental rights, thereby providing tools for balancing of human-animals interests. This article focuses on the re-evaluation of animal protection from an animal and constitutional point of view.
Intra-arterial tirofiban in a male nonagenarian with acute ischemic stroke: A case report
Authors: Ding Xianhui , Gu Ao , Yang Qian , Zhou Zhiming , Shi Xiaolei
Published: January 2020

Nonagenarians with acute ischemic stroke tend to have a higher mortality and morbidity than younger patients. Tirofiban is a glycoprotein IIb/IIIa antagonist that has a therapeutic potential for ischemic stroke. Here, we provide a case report of a 93-year-old male patient with acute ischemic stroke. He presented with right-sided hemiparesis for 2 hours (National Institute of Health Stroke Scale, NIHSS = 23). Immediate treatment with endovascular tirofiban infusion achieved an improvement of intracranial blood flow and a progressively decreased NIHSS one day after admission (NIHSS = 16) and then seven days after admission (NIHSS = 7). After a follow-up of 90 days, the modified ranking score was 2. This case report suggests that endovascular application with tirofiban may be a favorable option for treating nonagenarians presenting with acute ischemic stroke and warrants further study.

Authors: AlRabiah Haitham , Homoda Atef , Bakheit Ahmed , AE Mostafa Gamal
Published: January 2020

Polyvinyl chloride (PVC) membrane sensors were constructed and developed for the determination of procainamide HCl (PR). Three membrane sensors incorporating α-, β- and γ- cyclodextrin (CD) as ionophores with potassium tetrakis (4-chlorophenyl) borate (KTpClPB) as the ion additive, o-nitro phenyl ether (o-NPOE) as the plasticizer and a PVC matrix. The reaction mechanisms were based on inclusion complexes. The developed α- and β- CD sensors exhibited near-Nernstian profile, whereas γ- CD showed a non-Nernstian response. At pH 4 -8, the sensors exhibited a calibration range for PR of 10-3to 10−6, and the detection limits were 2.40 × 10-6, 2.12 × 10-6, 2.40 × 10-6for α-, β- and γ- CD sensors, respectively. Interference was investigated by studying the selectivity coefficient values of the test sensors, which indicated that the methods were free from interference from investigated species. The determination of PR exhibited high recovery and favorable relative standard deviation using the investigated sensors. The sensors were subsequently used for the quantification of PR in a pharmaceutical formulation and the potentiometric results agreed with those of a spectrophotometric method. A molecular docking (MD) study was used to predict the structure of the inclusion complexes of PR (guest) and α- or β- or γ-CD (host). The study results indicated that the formed complexes were stable with sufficient binding energy.
Development of a Gold Immunochromatographic Assay Method Using Candida Biofilm Antigen as a Bioreceptor for Candidiasis in Rats
Authors:   Masfufatun, Hariyanto Loo ,   Harsono, Baktir Afaf
Published: January 2020

The gold immunochromatography assay (GICA), a new immunochromatography technique, uses a nitrocellulose membrane as a carrier and a colloidal gold-labeled antigen or antibody as a tracer (bioreceptor). This technology has many advantages over other immunoassays, including its simplicity, rapidity, cheapness, and the lack of a requirement for special training or expensive equipment, and it can be used to detect either antigens or antibodies. Therefore, we chose to develop this method for the diagnosis of candidiasis in Indonesia. The objective of the present study was to develop a diagnostic test for Candida albicans in rats using the GICA method. GICA bioreceptors were developed from biofilm antigens isolated from biofim Candida albicans grown on the surface of nitrocellulose membranes. The formation of biofilms was confirmed using scanning electron microscopy. Antigen levels as bioreceptors were optimized by using the immuno dot method. The samples to be analyzed were antibody serum, in the form of blood serum samples from heart mice that have been induced to become candidiasis. To this end, we optimized the antigen and antibody volumes necessary to make this diagnosis. The results show that the optimum concentration of antigen to be used in the test is 2.5 μg/μL and the optimum volume of antibody is 10 μL. The control rats produced a single red stripe on the control line and the candidiasis rat samples produced a double red stripe, with the bottom line being the control line and the upper line the test line. The test chip was successfully used for the diagnosis of candidiasis in rats and given the name “Candiday Kit.”. We anticipate that this test will be suitable for the diagnosis of candidiasis in humans
Large amplitude vibration of doubly curved FG-GRC laminated panels in thermal environments
Authors: Shen Hui-Shen , Xiang Yang , Fan Yin
Published: January 2020

A study on the large amplitude vibration of doubly curved graphene-reinforced composite (GRC) laminated panels is presented in this paper. A doubly curved panel is made of piece-wise GRC layers with functionally graded (FG) arrangement along the thickness direction of the panel. A GRC layer consists of polymer matrix reinforced by aligned graphene sheets. The material properties of the GRC layers are temperature dependent and can be estimated by the extended Halpin-Tsai micromechanical model. The modelling of the large amplitude vibration of the panels is based on the Reddy’s higher order shear deformation theory and the effects of the von Kármán geometric nonlinearity, the panel-foundation interaction and the temperature variation are included in the derivation of the motion equations of the panels. The solutions for the large amplitude vibration of the doubly curved FG-GRC laminated panels are obtained by applying a two-step perturbation approach. A parametric study is carried out to determine the influences of foundation stiffness, temperature variation, FG distribution pattern, in-plane boundary condition and panel curvature ratio on the natural frequencies and the nonlinear to linear frequency ratios of the doubly curved FG-GRC laminated panels.
Numerical simulation of welding distortions in large structures with a simplified engineering approach
Authors: Perić Mato , Seleš Karlo , Tonković Zdenko , Lovrenić-Jugović Martina
Published: January 2020

This paper presents an efficient thermo-elastoplastic method for the prediction of welding-induced distortions in a large panel structure. It is based on a shell/3D modeling technique which was proposed and experimentally validated in the authors’ previous study. Two numerical examples are analyzed to evaluate the accuracy and efficiency of the present method. In the first example, the recommendations for the estimation of the minimum 3D zone size in the shell/3D model reported in the authors’ previous work are verified, in comparison with the full 3D model, on a T-joint model consisting of plates with different thicknesses. It is shown that the shell/3D modeling technique provides a significant reduction in the computational time needed for the simulation of the welding process and thus enables efficient thermo-elastoplastic analyses on large structures. In the second example, the proposed model is validated on a large panel structure by corresponding the experimental data and inherent strain solutions from the literature.

Participar da Santidade de Deus
Authors: Bingemer Maria Clara Lucchetti
Published: January 2020

O artigo focaliza o chamado à santidade segundo o Cristianismo seguindo a exortação de Francisco, chamado dirigido a toda a Igreja. Examina como a história das ideias, a filosofia e a teologia utilizam o conceito de santo e santidade, detendo-se especialmente na figura do santo como testemunha. Em seguida lança o olhar sobre a realidade da América Latina, examinando como algumas teologias contextuais perceberam aí a presença de uma santidade primordial, anterior a toda definição e a toda apropriação mesmo por parte da Igreja. Mais adiante reflete como a santidade tem uma configuração crística, que procura alcançar a proximidade e a semelhança com Jesus Cristo. Nesse sentido examina as opções que o Papa Francisco recomenda como caminho para aceder a essa identificação com o Senhor. Finalmente focaliza a categoria que o Papa privilegia como caminho para responder ao chamado à santidade: o discernimento.

The Language of Crisis and the Problem of Historical Meaning. Nietzsche, Heidegger, Kolakowski
Authors: Popa Gabriel
Published: January 2020

The main task of our paper is to emphasize the relationship between the dominant historical paradigm which emerges at the end of the 19th Century and the contemporary embrace of  crisis language. We will see that the dawn of the historical school and of historicism in general brings forth the dissolution of the last remains of the Absolute figures, thus leaving us in front of desolation and emptiness. Post-modern skepticism and relativism became the dominant features that shape our intellectual and moral landscape, trapping us within a seemingly inescapable situation of crisis which finds its own language and expressions. Our journey will trace back to the origins and main motivations of what has been described as a constancy of the post-modern condition as it is described by Kolakowski in one of his essays from 1989, finding along our way writers like Heidegger and Nietzsche which we think  are our best witnesses of the main variations of the relation between the meaning of history and the crisis-consciousness.
Digestibility and energy content of Paulownia (Paulownia elongata S.Y.Hu) leaves
Authors: Ganchev G. , Ilchev А. , Koleva А.
Published: January 2020

Abstract. The aim of the study was to determine the digestibility and energy content of Paulownia elongata S.Y.Hu leaves after leaf fall. Leaves together with petioles were dried at room temperature and milled with a roughage mill before feeding to animals. A classical digestion trial was performed, with three rams weighing 55.4kg on average, by determining the chemical composition of consumed feed, feed leftovers and excreted faeces. Digestibility was evaluated as difference in the amount of ingested nutrients and nutrients excreted with faeces and it was determined to be 50.72, 52.08, 31.63, 54.09, 55.15 and 56.06% for dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fibre (CF) and nitrogen-free extract (NFE). The energy value for ruminants calculated on the basis of chemical composition and established digestibility was 8.29 MJ digestible energy (DE)/kg DM, 6.55 MJ metabolizable energy (ME)/ kg DM, 0.59 feed units for milk (FUM)/kg DM and 0.52 feed units for growth (FUG)/kg DM.

Authors: Khatri N. , Pokhrel D. , Pandey B.P. , Pant K.R. , Bista M.
Published: January 2020

Abstract. A study was conducted at four Village Development Committees (Masuriya, Udashipur, Basauti and Pahalmanpur) of Kailali dis- trict, Far western Region, Nepal in 2016/17 to find out the effect of different storage materials on the seed moisture content and germination percentage of wheat. Seeds of wheat were packed using five storage materials (metal seed bin, earthen pot, purdue improved crop storage / Pics/ bag, gunny bag and super grain bag). The stored seed samples were drawn at three-month intervals starting from May 2016 to January 2017. The experiment was arranged in Randomized Complete Block Design (RCBD) in four replications. The results of analysis of variance revealed that the effect of storage materials was significant (P≤0.05) on seed moisture content and seed germination of wheat. After nine months of storage, the seeds stored in Pics bag recorded the lowest moisture (13.3%) and temperature (26.4°C), and the highest germination percentage (91.75%). The lowest quality performance (high moisture and temperature, low germination) of stored seeds was observed in an earthen pot. From the results obtained, it was concluded that wheat seed could be stored for a long time in Pics bag without deteriorating its quality parameters.
Five-Option vs Four-Option Multiple-Choice Questions
Authors: Budiyono Bartholomeus
Published: January 2020

Abstract: Multiple-choice questions (MCQs) may provide test takers with three, four, or five options and are appreciated for reliability and economic scoring. Five-option MCQs demand much more energy, experience, time, and expertise and may probably be considered to be more difficult four-option and three-option MCQs. Previous studies involved a great number of questions and participants. This study investigated the difference between five-option and four-option MCQs through deletion of non-functioning distracters (NFDs) in proportion to a classroom-based test by administering 28 MCQs to two intact classes of 34 participants. The results show that there was significant difference in participants’ scores (p 0.030< 0.05), significant difference in the number of NFDs (p 0.01<0.05), no significant difference in item facility (p 0.485>0.05), and significant difference in item discrimination (p 0.01<0.05).   Classroom teachers are free to choose either the 5-option or 4-option version, depending on the purpose of the test.

Published: January 2020

Reading skill is important especially for non-English departments students like those of Information Technology Department at State Polytechnic of Malang. However, based on the observation and the results of the tests, the students showed low performance and motivation in reading English written texts even though the texts were on IT related subjects. Therefore, the students were introduced to Kit-Built Concept Mapping to help them overcome the problems. This study is Classroom Action Research (CAR) to analyze the implementation of the method to help the students improve their reading skills as well as motivation to read. There were some procedures they had to follow and some tests to do in this study. This study was said to be successful and stopped when the students’ scores met the criteria of success previously determined, namely more than 50% of them had the average score more than 66 or B in accordance with the State Polytechnic of Malang Academic Handbook. After the first and second cycles, the average scores obtained showed an improvement both in the first and second cycles. Hence, after the two average scores were analyzed by the paired t-test it was found that there was no significant difference between them. Accordingly, it can be said that this method was not fully successful in improving the students' reading skills even though from the questionnaire and interview showed the students’ interests and motivation to read English written texts more than before.

Published: January 2020

Textbooks are one of the important components in language program. It plays significant roles to provide the basis for content of the lesson, the balance of skills taught and the kinds of language practice that students involve in (Richards, 2001). Due to this circumstance, the use of qualified and relevant textbook is highly required to facilitate learning and bring actual learning experience to students. In addition to the selection, the evaluation of the textbooks in EFL context are also at the utmost importance to evaluate whether a particular textbook used in the classroom is a good textbook or not. This study was aimed to evaluate the suitability of the Survival English textbook based on the Content and Contexts criteria of a good English textbook, which proposed by Mukundan (2011), Mukundan et al (2012) and Miekley (2015). The list of statements in a form of questionnaire were addressed to identify 50 students’ assessment of six topics being discussed in the textbook, which was supported by the qualitative data from the interview session. The results of the study were found substantial as the input to develop further Survival English textbook
A Learning Strategy Use and Speaking Skills in the Indonesian Context
Authors: Wahyuni Sri
Published: January 2020

Abstract—This study investigates language learning strategies used by Indonesian tertiary students in learning to speak English. The study addresses what learning strategies the students use; what strategy group and individual strategy they favour; and whether speaking skills significantly affect strategy use. This paper reports the quantitative results of a larger mixed-methods study drawing on questionnaire (n = 65) and students’ speaking grades (n = 65) obtained from students at Gajayana University of Malang in Indonesia. The study demonstrates that the students used a wide range of strategies that spread over six strategy groups of Oxford’s taxonomy (1990). Advanced and elementary students favoured compensation strategies, and intermediate students, metacognitive strategies. As regards individual strategy, advanced students favoured ‘using a circumlocution or synonym’; intermediate students, ‘paying attention’; and elementary students, ‘using resources for receiving and sending messages’. The study also shows that speaking skills significantly affected the use of affective strategies only. The paper concludes by discussing implications for theory and practice.

The students were supposed to write their favorite story. In the post-test, the student was also asked to write a narrative paragraph based on the sequenced pictures given. The treatment was given after pre-test by the teacher. The teacher taught narrative text by using picture of sequence to see the difference of students’ ability in writing narrative paragraph.  The sequenced pictures were used as a media in teaching learning process for the length of pre-test and post-test. The result of data analysis turned out to prove that there was a significant different between the mean score of the pre-test (60) and the post-test (73). In fact, the mean score of the post-test was significantly higher than that of the pre-test. The result of t-test (10.670) was higher than t-table (2.064) for .05 percent level and (2.797) for .01 percent level). it can be concluded that sequenced pictures help students achieve better performance in writing narrative.
Uncertain Context: Uncertainty Quantification in Machine Learning
Authors: Jalaian Brian , Lee Michael , Russell Stephen
Published: January 2020

Machine learning and artificial intelligence will be deeply embedded in the intelligent systems humans use to automate tasking, optimize planning, and support decision‐making. However, many of these methods can be challenged by dynamic computational contexts, resulting in uncertainty in prediction errors and overall system outputs. Therefore, it will be increasingly important for uncertainties in underlying learning‐related computer models to be quantified and communicated. The goal of this article is to provide an accessible overview of computational context and its relationship to uncertainty quantification for machine learning, as well as to provide general suggestions on how to implement uncertainty quantification when doing statistical learning. Specifically, we will discuss the challenge of quantifying uncertainty in predictions using popular machine learning models. We present several sources of uncertainty and their implications on statistical models and subsequent machine learning predictions.

Published: January 2020

In the present study, polyurethane (PU) nanocomposite scaffolds containing bioactive glass nanoparticles (BG-NPs) were successfully fabricated through the electrospinning process. The BG-NPs were synthesized through the sol–gel method. PU solutions (10% w/v) containing different weight percentages of the BG-NPs (5, 10 and 15 wt.%) in dimethylformamide/tetrahydrofuran were prepared. To determine both the size of BG-NPs and the diameter of the nanofibers, transmission electron microscopy and scanning electron microscopy were carried out. The surface morphology, mechanical properties, bioactivity and degradation rate of the scaffolds were studied. Fourier transform infrared spectroscopy, X-ray diffraction and energy-dispersive X-ray spectroscopy confirmed the presence of BG within the scaffolds. The tensile strength of nanocomposite scaffolds was in the range 5–8 MPa, which is in good agreement with the tensile strength of cancellous bone tissue. MG63 cells attached to and proliferated well within the scaffolds; therefore, cellular growth was also improved in the nanocomposite scaffolds. Based on the results, the novel PU/BG-NP (10 wt.%) nanocomposite scaffold has a great potential to be applied in cancellous bone tissue engineering.

Published: January 2020

The mechanical properties of soil could be affected by its temperature change and these effects may lead to additional issues in the thermo-mechanical behaviour of energy piles. Laboratory experiments were conducted to assess the thermo-mechanical behaviour of a small-scale instrumented energy pile installed in a saturated clay at different stress histories. The energy pile was subjected to five heating/cooling cycles. The experimental programme involved monitoring the changes in the surrounding soil temperature, pile-head displacement, pile axial load and pile-tip resistance as the temperature of the pile changed. The results show that the thermo-mechanical behaviour of the energy pile depended on the stress history of the surrounding saturated clay. The normally consolidated clay showed a higher irreversible pile-head settlement and pile-tip resistance compared with the overconsolidated clay. This behaviour could be explained in light of the expected contraction thermally induced volume change of the normally consolidated clay that could induce an additional negative skin friction on the pile. Moreover, the observed mechanical engineering behaviour of the energy pile under thermal heating/cooling cycles could be explained in terms of the expected degradation of shaft friction due to the cyclic thermally induced interface shear stress.
Approaches to automated land subdivision using binary search algorithm in zoning applications
Authors: Koc Ismail , Cay Tayfun , Babaoglu Ismail
Published: January 2020

The planned development of urban areas depends on zoning applications. Although zoning practices are performed using different techniques, the parcelling operations that shape the future view of the city are the same. Preparing the parcelling plans is an important step that has a direct impact on ownership structure and reallocation. Parcelling operations are traditionally handled manually by a technician. This is a serious problem in terms of time and cost. In this study, by taking the zoning legislation, the production of a pre-land subdivision plan has been automatically performed for a region of Konya, which is one of the major cities in Turkey. The parcelling processes have been performed in three different ways: the first parcelling technique is parcelling with edge values, the second is parcelling with area values and the third is parcelling using both edge and area values together. For the entire parcelling process, the area of the parcel has been calculated using the Gauss method. Moreover, to effectively determine the boundaries and to calculate the parcel area in the parcelling process, the binary search technique has been used in all the methods. The experimental results show that the parcelling operations were carried out very quickly and successfully.
Effects of two admixtures on the axial compression of concrete-filled fibreglass tubes

Published: January 2020

This paper reports on an investigation into the influence of an expansive admixture (EA) and fly ash (FA) on the axial compressive behaviour of concrete-filled glass-fibre-reinforced polymer (GFRP) tube columns. The effect of EA and FA on the compressive strength and restrained expansion ratio was studied for two concrete strength grades, and optimised mixtures of expansive FA concrete were selected. It was found that the desired concrete strength and maximum expansion was obtained with 12% substitution of EA and 10% substitution of FA. For this study, 12 concrete-filled GFRP tube columns of circular cross-section were designed and fabricated considering parameters including the GFRP tube thickness, EA content, FA dosage and concrete strength. Their axial compressive behaviour was investigated through their failure modes, load-carrying capacity, ultimate stress and stress–strain curves. The results showed that increases in the thickness of the GFRP tube and EA content can enhance the axial compressive strength of concrete-filled GFRP tube columns. The theoretical ultimate load results showed good agreement with the experimental data.
Seismic vulnerability assessment of timber roof structures: criteria and procedures
Authors: Parisi Maria Adelaide , Tardini Chiara
Published: January 2020

Timber roof structures have a strong influence on the behaviour of masonry buildings during earthquakes. In a seismic event, they may link walls and favour the development of a positive global response or they may suffer damage that can extend to masonry elements. From the perspective of risk mitigation, basic criteria and procedures for assessing the seismic vulnerability of timber roof structures are needed. After extended research, the main factors determining seismic vulnerability in such structures were identified. The steps of an assessment procedure developed within the research programme are discussed in this paper. The procedure comprises initial visual inspection for collecting data and information on the main parameters that are significant in seismic conditions, and their subsequent classification according to a grading system. Structural criticalities are thus identified, which may possibly be reduced. In the applications and case studies performed so far, the procedure has proven useful for focusing attention on the seismic qualification of timber structures that were originally conceived with regard to vertical loads.

Authors: Voronkov S. S.
Published: January 2020

The food market is an important element of each country’s economy. Its high rates of development contribute to the high rate of development of the economy as a whole. The high level of availability of food produced domestically forms national food security. The article analyzes the development of the food market in recent years, identifies key factors affecting its development. The rationale for the need to move to a new stage in the development of the food market – the formation of a two-tier management system – has been formulated. The author justifies the choice of strategy as a priority document, with the help of which it is possible to achieve the maximum result of development. The choice of the food market in St. Petersburg and the Leningrad Region as an object of development strategy is substantiated. The food market of the regions of St. Petersburg and the Leningrad Region is one of the largest markets in the country in terms of the volume of consumption of products and the total retail turnover. St. Petersburg, which implements the strategy for the development of socio-economic development until 2030, is the leading domestic region in the field of strategy. Forming a strategy for the development of the food market will strengthen this status. The implementation of the objectives of the food market development strategy contributes to the implementation of strategies for the socio-economic development of territories, strengthening its position in the ranking of regional competitiveness, attracting additional investments, and developing the infrastructure of the region. Based on the strategy of V.L. Kvint has developed a hierarchy of strategies with the definition of a place in it for the development of a regional food market. Ten principles were formed on the basis of which it is possible to form a regional strategy for the development of the food market in St. Petersburg and the Leningrad Region. The formulated principles are distributed according to the formed classification of principles.
