Estimating Lower Extremity Running Gait Kinematics with a Single Accelerometer: A Deep Learning Approach
Authors: Gholami Mohsen , Napier Christopher , Menon Carlo
Published: May 2020

Abnormal running kinematics are associated with an increased incidence of lower extremity injuries among runners. Accurate and unobtrusive running kinematic measurement plays an important role in the detection of gait abnormalities and the prevention of injuries among runners. Inertial-based methods have been proposed to address this need. However, previous methods require cumbersome sensor setup or participant-specific calibration. This study aims to validate a shoe-mounted accelerometer for sagittal plane lower extremity angle measurement during running based on a deep learning approach. A convolutional neural network (CNN) architecture was selected as the regression model to generalize in inter-participant scenarios and to minimize poorly estimated joints. Motion and accelerometer data were recorded from ten participants while running on a treadmill at five different speeds. The reference joint angles were measured by an optical motion capture system. The CNN model predictions deviated from the reference angles with a root mean squared error (RMSE) of less than 3.5° and 6.5° in intra- and inter-participant scenarios, respectively. Moreover, we provide an estimation of six important gait events with a mean absolute error of less than 2.5° and 6.5° in intra- and inter-participants scenarios, respectively. This study highlights an appealing minimal sensor setup approach for gait analysis purposes.
BioMove: Biometric User Identification from Human Kinesiological Movements for Virtual Reality Systems
Authors: Olade Ilesanmi , Fleming Charles , Liang Hai-Ning
Published: May 2020

Virtual reality (VR) has advanced rapidly and is used for many entertainment and business purposes. The need for secure, transparent and non-intrusive identification mechanisms is important to facilitate users’ safe participation and secure experience. People are kinesiologically unique, having individual behavioral and movement characteristics, which can be leveraged and used in security sensitive VR applications to compensate for users’ inability to detect potential observational attackers in the physical world. Additionally, such method of identification using a user’s kinesiological data is valuable in common scenarios where multiple users simultaneously participate in a VR environment. In this paper, we present a user study (n = 15) where our participants performed a series of controlled tasks that require physical movements (such as grabbing, rotating and dropping) that could be decomposed into unique kinesiological patterns while we monitored and captured their hand, head and eye gaze data within the VR environment. We present an analysis of the data and show that these data can be used as a biometric discriminant of high confidence using machine learning classification methods such as kNN or SVM, thereby adding a layer of security in terms of identification or dynamically adapting the VR environment to the users’ preferences. We also performed a whitebox penetration testing with 12 attackers, some of whom were physically similar to the participants. We could obtain an average identification confidence value of 0.98 from the actual participants’ test data after the initial study and also a trained model classification accuracy of 98.6%. Penetration testing indicated all attackers resulted in confidence values of less than 50% (<50%), although physically similar attackers had higher confidence values. These findings can help the design and development of secure VR systems.

Published: May 2020

The potential of MR thermometry (MRT) fostered the development of MRI compatible radiofrequency (RF) hyperthermia devices. Such device integration creates major technological challenges and a crucial point for image quality is the water bolus (WB). The WB is located between the patient body and external sources to both couple electromagnetic energy and to cool the patient skin. However, the WB causes MRT errors and unnecessarily large field of view. In this work, we studied making the WB MRI transparent by an optimal concentration of compounds capable of modifying T 2 * relaxation without an impact on the efficiency of RF heating. Three different T 2 * reducing compounds were investigated, namely CuSO 4 , MnCl 2 , and Fe 3 O 4 . First, electromagnetic properties and T 2 * relaxation rates at 1.5 T were measured. Next, through multi-physics simulations, the predicted effect on the RF-power deposition pattern was evaluated and MRT precision was experimentally assessed. Our results identified 5 mM Fe 3 O 4 solution as optimal since it does not alter the RF-power level needed and improved MRT precision from 0.39 ° C to 0.09 ° C. MnCl 2 showed a similar MRT improvement, but caused unacceptable RF-power losses. We conclude that adding Fe 3 O 4 has significant potential to improve RF hyperthermia treatment monitoring under MR guidance.
Software-Defined Networking Approaches for Link Failure Recovery: A Survey
Authors: Ali Jehad , Lee Gyu-min , Roh Byeong-hee , Ryu Dong Kuk , Park Gyudong
Published: May 2020

Deployment of new optimized routing rules on routers are challenging, owing to the tight coupling of the data and control planes and a lack of global topological information. Due to the distributed nature of the traditional classical internet protocol networks, the routing rules and policies are disseminated in a decentralized manner, which causes looping issues during link failure. Software-defined networking (SDN) provides programmability to the network from a central point. Consequently, the nodes or data plane devices in SDN only forward packets and the complexity of the control plane is handed over to the controller. Therefore, the controller installs the rules and policies from a central location. Due to the central control, link failure identification and restoration becomes pliable because the controller has information about the global network topology. Similarly, new optimized rules for link recovery can be deployed from the central point. Herein, we review several schemes for link failure recovery by leveraging SDN while delineating the cons of traditional networking. We also investigate the open research questions posed due to the SDN architecture. This paper also analyzes the proactive and reactive schemes in SDN using the OpenDayLight controller and Mininet, with the simulation of application scenarios from the tactical and data center networks.

Published: May 2020

At present, supporting e-learning with interactive virtual campuses is a future goal in education. Models that measure the levels of acceptance, performance, and academic efficiency have been recently developed. In light of the above, we carried out a study to evaluate a model for which architecture design, configuration, metadata, and statistical coefficients were obtained using four Learning Management Systems (LMSs). That allowed us to determine reliability, accuracy, and correlation, using and integrating the factors that other researchers have previously used, only using isolated models, such as Anxiety–Innovation (AI), Utility and Use (UU), Tools Learning (TL), System Factors (SF), Access Strategies (AS), Virtual Library (VL), and Mobile Use (MU). The research was conducted over one year in nine groups. The results from an LMS Classroom, architecturally and configuration-wise, had the highest level of performance, with an average of 73% when evaluated using statistical coefficients. The LMS Classroom had a good acceptance and a greater impact: SF, 82%, AI, 80%, and VL, 43%, while out of the seven factors, those with the most significant impact on academic efficiency were TL, 80%, VL, 82%, and MU, 85%.
Ecologically Embedded Design in Manufacturing: Legitimation within Circular Economy
Authors: Trollman Hana , Colwill James , Brejnholt Alan
Published: May 2020

Circular economy has gained momentum since the 1970s as a regenerative alternative to the traditional linear economy. However, as the circular economy has gone mainstream, circularity claims have become fragmented and remote, consisting of indirect contributions, such as the life extension of other products and the use of waste as feedstock, without addressing the actual cause of waste. The present study aims to identify the strategic motivations of manufacturers participating in the circular economy and the corresponding relationship to ecological embeddedness. This paper explores the circular economy in manufacturing through existing products on the market and their relationship to eco-design by considering the product, packaging, and its production. Legitimacy is found to be a decisive factor in whether the type of circular economy strategy manufacturers adopt yields ecological benefits. The results from the case study of products clearly indicate the superiority of ecological embeddedness, as a form of circularity supporting strong sustainability. Finally, a novel template is proposed to support the implementation of ecological embeddedness in manufacturing.
Adaptation, Official Development Assistance, and Institution Building: The Case of the Caribbean Community Climate Change Centre
Authors: Rosenberg Jonathan
Published: May 2020

The Caribbean Community Climate Change Centre was launched in 2005, culminating a process that included three precursor projects: Caribbean Planning for Adaptation to Climate Change (1997–2001); Adapting to Climate Change in the Caribbean (2001–2004); and Mainstreaming Climate Change (2003–2009). Each benefited from multiple sources of official development assistance (ODA), clearly defined tasks, and leadership from the region’s scientific and technical communities. Shared goals and principles across the projects included: use of bottom-up participatory methods; building the technical capacity of national and regional institutions; mainstreaming adaptation in economic development programs; and partnering with governmental, non-governmental, and private sector organizations. This article applies concepts from the global environmental politics literature on interplay, environmental policy integration, and regional governance to trace the institutionalization of the Centre. Fifteen semi-structured interviews and reviews of project documents reveal how the Centre built capacity to plan and manage projects, act as a regional hub for technical support and data, participate in the multi-level political interplay required to secure ODA, while exploring other funding sources; and the extent to which it has been able to maintain its commitment to bottom-up, participatory methods, effective internal and external communications, social assessment, and monitoring and evaluation of projects.
Human Botulism in France, 1875–2016
Authors: Rasetti-Escargueil Christine , Lemichez Emmanuel , Popoff Michel R.
Published: May 2020

Botulism is a rare but severe disease which is characterized by paralysis and inhibition of secretions. Only a few cases had been reported at the end of the 19th century in France. The disease was frequent during the second world war, and then the incidence decreased progressively. However, human botulism is still present in France with 10–25 cases every year. Food-borne botulism was the main form of botulism in France, whereas infant botulism (17 cases between 2004 and 2016) was rare, and wound and inhalational botulism were exceptional. Type B was the prevalent botulism type and was mainly due to consumption of home-made or small-scale preparations of cured ham and to a lesser extent other pork meat products. In the recent period (2000–2016), a wider diversity of botulism types from various food origin including industrial foods was reported. Severe cases of type A and F botulism as well as type E botulism were more frequent. Albeit rare, the severity of botulism justifies its continued surveillance and recommendations to food industry and consumers regarding food hygiene and preservation practices.
Monocytes in Uremia
Authors: Girndt Matthias , Trojanowicz Bogusz , Ulrich Christof
Published: May 2020

Monocytes play an important role in both innate immunity and antigen presentation for specific cellular immune defense. In patients with chronic renal failure, as well as those treated with maintenance hemodialysis, these cells are largely dysregulated. There is a large body of literature on monocyte alterations in such patients. However, most of the publications report on small series, there is a vast spectrum of different methods and the heterogeneity of the data prevents any meta-analytic approach. Thus, a narrative review was performed to describe the current knowledge. Monocytes from patients with chronic renal failure differ from those of healthy individuals in the pattern of surface molecule expression, cytokine and mediator production, and function. If these findings can be summarized at all, they might be subsumed as showing chronic inflammation in resting cells together with limited activation upon immunologic challenge. The picture is complicated by the fact that monocytes fall into morphologically and functionally different populations and population shifts interact heavily with dysregulation of the individual cells. Severe complications of chronic renal failure such as impaired immune defense, inflammation, and atherosclerosis can be related to several aspects of monocyte dysfunction. Therefore, this review aims to provide an overview about the impairment and activation of monocytes by uremia and the resulting clinical consequences for renal failure patients.
Monitoring Phenolic Compounds in Rice during the Growing Season in Relation to Fungal and Mycotoxin Contamination
Authors: Giorni Paola , Rastelli Silvia , Fregonara Sofia , Bertuzzi Terenzio
Published: May 2020

Total phenolic content (TPC) and several phenolic acids present in rice grains were compared with fungal infection and mycotoxin presence throughout the growing season. Samples of 4 rice varieties were collected in 2018 and 2019 at 3 different plant phenological stages. Total fungal and main mycotoxigenic fungi incidence were checked and mycotoxin content was analysed. On the same samples, TPC and the concentration of 8 main phenolic acids (chlorogenic acid, caffeic acid, syringic acid, 4-hydroxybenzoic acid (4-HBA), p-coumaric acid, ferulic acid, protocatecuic acid and gallic acid) were measured. The results showed significant differences between years for both fungal incidence and mycotoxin presence. In 2018 there was a lower fungal presence (42%) than in 2019 (57%) while, regarding mycotoxins, sterigmatocystin (STC) was found in almost all the samples and at all growing stages while deoxynivalenol (DON) was found particularly during ripening. An interesting relationship was found between fungal incidence and TPC, and some phenolic acids seemed to be more involved than others in the plant defense system. Ferulic acid and protocatecuic acid showed a different trend during the growing season depending on fungal incidence and resulted to be positively correlated with p-coumaric acid and 4-HBA that seem involved in mycotoxin containment in field.

Published: May 2020

Pore-forming toxins are alluring tools for delivering biologically-active, impermeable cargoes to intracellular environments by introducing large conductance pathways into cell membranes. However, the lack of regulation often leads to the dissipation of electrical and chemical gradients, which might significantly affect the viability of cells under scrutiny. To mitigate these problems, we explored the use of lysenin channels to reversibly control the barrier function of natural and artificial lipid membrane systems by controlling the lysenin’s transport properties. We employed artificial membranes and electrophysiology measurements in order to identify the influence of labels and media on the lysenin channel’s conductance. Two cell culture models: Jurkat cells in suspension and adherent ATDC5 cells were utilized to demonstrate that lysenin channels may provide temporary cytosol access to membrane non-permeant propidium iodide and phalloidin. Permeability and cell viability were assessed by fluorescence spectroscopy and microscopy. Membrane resealing by chitosan or specific media addition proved to be an effective way of maintaining cellular viability. In addition, we loaded non-permeant dyes into liposomes via lysenin channels by controlling their conducting state with multivalent metal cations. The improved control over membrane permeability might prove fruitful for a large variety of biological or biomedical applications that require only temporary, non-destructive access to the inner environment enclosed by natural and artificial membranes.
Assessment and Valuation of Groundwater Ecosystem Services: A Case Study of Handan City, China
Authors: Yang Xuyang , Liu Jian
Published: May 2020

Groundwater is important for maintaining ecosystem balance. However, the ecological value of groundwater is always undervalued, while its value as water resources is emphasized. Thus, this paper divided the systematic valuation of groundwater-dependent ecosystems (GDEs) into three categories, and its services into four categories based on the utilization. In addition, a service valuation system was developed, with ten indicators and nine assessment models for the GDEs. We then used this model to value the GDEs services of Handan city in 2015 as a case study, with seven relevant indicators. The results show that the total value of Handan’s GDEs is 9.10 billion Renminbi (RMB, Chinese unit of currency), including a direct use value of 3.53 billion, and an indirect use value of RMB 5.57 billion. These results highlight the significant indirect use value of GDEs. Consequently, groundwater resources should be rationally exploited to maximize both direct and indirect service values on the basis of a comprehensive understanding of the inherent value of the resource.

Authors: Greco Aldo , De Luca Davide Luciano , Avolio Elenio
Published: May 2020

An in-depth analysis of historical heavy rainfall fields clearly constitutes an important aspect in many related topics: as examples, mesoscale models for early warning systems and the definition of design event scenarios can be improved, with the consequent upgrading in the prediction of induced phenomena (mainly floods and landslides) into specific areas of interest. With this goal, in this work the authors focused on Calabria region (southern Italy) and classified the main precipitation systems through the analysis of selected heavy rainfall events from high resolution rain gauge network time series. Moreover, the authors investigated the relationships among the selected events and the main synoptic atmospheric patterns derived by the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 Reanalysis dataset, in order to assess the possible large-scale scenarios which can induce heavy rainfall events in the study area. The obtained results highlighted: (i) the importance of areal reduction factors, rainfall intensities and amounts in order to discriminate the investigated precipitations systems for the study area; (ii) the crucial role played by the position of the averaged low-pressure areas over the Mediterranean for the synoptic systems, and by low-level temperature for the convective systems.

The Ugii Nuur Lake is not only one of the small hydrologically closed lakes located in the Orkhon River Basin in Central Mongolia but also the most vulnerable area for global climate change. Therefore, this study aims to investigate the impacts of recent global climate change on the water surface area. The data we analyzed were various measured hydro-meteorological variables of the lake basin and the lake surface area, which was estimated from Landsat series satellite data from 1986 to 2018. The methods we used were Mann-Kendall (MK), Innovative trend analysis method (ITAM), Sen’s slope estimator test, correlation, and regression analysis. The variation of lake water surface area has a strong positive correlation with the change of the lake water level (r = 0.95). The Mann-Kendall trend analysis has indicated that under a significant decrease in total annual precipitation ( Z   = −0.902) and inflow river discharge ( Z   = −5.392) and a considerable increase in total annual evaporation ( Z = 4.385) and annual average air temperature ( Z   = 4.595), the surface area of the Ugii Nuur Lake has decreased sharply ( Z = −6.021). The total annual evaporation (r = −0.64) and inflow river discharge (r = 0.67) were the essential hydro-meteorological factors affecting the surface area of the Ugii Nuur Lake. The lake surface area decreased by 13.5% in 2018 compared with 1986. In the near future, it is vital to conduct scientific studies considering the volume of lake water, groundwater, and the anthropogenic impact.
Attitude and Actual Behaviour towards Water-Related Green Infrastructures and Sustainable Drainage Systems in Four North-Western Mediterranean Regions of Italy and France
Authors: Piacentini Simone Maria , Rossetto Rudy
Published: May 2020

Water-related green infrastructures (WrGIs), also known as blue infrastructures, and sustainable drainage systems (SuDSs) offer services such as stormwater runoff management, water purification, water storage at the intersection of the built environment, and natural systems by mimicking natural hydrological processes. While several papers document the reliability of such infrastructures in providing a variety of water-related services, few studies investigated the actual behaviour and the attitude of different stakeholders to understand the limitations and barriers in WrGIs/SuDSs implementation. In this paper, we investigated these issues by posing a set of questions to 71 qualified stakeholders in three Italian regions (Toscana, Liguria, and Sardegna) and one French region (Provence-Alpes-Côte d’Azur) in the northwestern Mediterranean. The results of the investigation largely show a lack of knowledge on these innovative solutions, although there is a general interest in their implementation both in the Italian and French regions. Barriers are also constituted by the scarcity of the demonstrators implemented, little knowledge on construction and maintenance costs, the absence of a proper regulatory framework, and of fiscal and financial incentives to support private citizens and companies. We finally suggest tools and soft measures that, in our opinion, may contribute to supporting the implementation of WrGIs/SuDSs, especially in view of adapting Mediterranean territories to the challenges posed by climate change. The results of our analyses may be reasonably up-scaled to the whole Mediterranean coastal region.
Aquatic Microplastic Research—A Critique and Suggestions for the Future
Authors: Weis Judith S.
Published: May 2020

While there are numerous papers on microplastics (mps) being published every week, there is a need for improvement for the field to mature. The papers reporting numbers found in water bodies cannot be compared because there are no standard methods for collection and analysis. It is clear that using nets for sampling misses most of the microfibers, which are the most abundant form when whole water samples are analyzed, and that microscopic identification has a very high error rate compared to chemical analytical equipment which can also identify the polymers. It is clear that most animals studied eat mps; we should learn what attracts the animals to the mps and what proportion pass right through and are defecated vs those that move into the tissues. It is considered that mps are a vector for transfer of toxic chemicals into the food chain. Let us investigate to what degree what proportion of contaminants are removed in the digestive system vs. staying bound tightly to the mps. Experimental studies should also use environmentally relevant doses and the shapes and sizes of mps that are most abundant in the environment.
Modeling Daily and Monthly Water Quality Indicators in a Canal Using a Hybrid Wavelet-Based Support Vector Regression Structure
Authors: Wang Yuxin , Yuan Yuan , Pan Ye , Fan Zhengqiu
Published: May 2020

Accurate prediction of water quality indicators plays an important role in the effective management of water resources. The models which studied limited water quality indicators in natural rivers may give inadequate guidance for managing a canal being used for water diversion. In this study, a hybrid structure (WA-PSO-SVR) based on wavelet analysis (WA) coupled with support vector regression (SVR) and particle swarm optimization (PSO) algorithms was developed to model three water quality indicators, chemical oxygen demand determined by KMnO4 (CODMn), ammonia nitrogen (NH3-N), and dissolved oxygen (DO), in water from the Grand Canal from Beijing to Hangzhou. Modeling was independently conducted over daily and monthly time scales. The results demonstrated that the hybrid WA-PSO-SVR model was able to effectively predict non-linear stationary and non-stationary time series and outperformed two other models (PSO-SVR and a standalone SVR), especially for extreme values prediction. Daily predictions were more accurate than monthly predictions, indicating that the hybrid model was more suitable for short-term predictions in this case. It also demonstrated that using the autocorrelation and partial autocorrelation of time series enabled the construction of appropriate models for water quality prediction. The results contribute to water quality monitoring and better management for water diversion.

Published: May 2020

The studies upstream of the petroleum industry include oil and gas geological exploration and are usually focused on geological, structural, geophysical, and modeling techniques. In this research, the application of a coupled microbiological–isotopic approach was explored to assess its potential as an adequate characterization and monitoring tool of geofluids in oilfield areas, in order to expand and refine the information acquired through more consolidated practices. The test site was selected within the Val d’Agri oilfield, where some natural hydrocarbon springs have been documented since the 19th century in the Tramutola area. Close to these springs, several tens of exploration and production wells were drilled in the first half of the 20th century. The results demonstrated the effectiveness of the proposed approach for the analysis of fluid dynamics in complex systems, such as oilfield areas, and highlighted the capacity of microbial communities to “behave” as “bio-thermometers”, that is, as indicators of the different temperatures in various subsurface compartments.
Investigation of host-specificity of phytopathogenic fungi isolated from woody plants
Authors: Zabiák Andrea , Károlyi Györk Milán , Sándor Erzsébet
Published: May 2020

Host-specificity is an important characteristic of fungal pathogens. Changing climate could create more appropriate environmental conditions for phytopathogens, thus formerly host-specify fungi could be able to colonize new hosts. Noxious plant pathogen fungi, which can infect several plant species are well-known worldwide. These genera may expand their range of hosts because of the appearance in new geographic areas due to climate change. This new exposure can result in serious problems in agriculture because of the lack of immunity. The susceptibility of apple tree was studied through testing pathogenicity in vitro with species isolated from walnut twigs and nuts, and identified by ITS sequences. Three of four tested species, Botryosphaeria dothidea, Diaporthe eres and Diplodia seriata colonized and necrotized the infected apple branches, while Juglanconis juglandina was not able to infect the twigs. Members of Botryosphaeriaceae were the most virulent, causing the largest lesions in the fastest way. This experiment draws attention to the threat of new host-pathogen connections, which can arise because of the favourable weather conditions and can spread between neighbouring cultures.
Insect base-protein: A new opportunity in animal nutrition
Authors: Toviho Odunayo , Bársony Péter
Published: May 2020

The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protein can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.

This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.

The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.

However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

Published: May 2020

While standing, we used baropodomerty to measure pressure on foot area. Human foot cause force reaction while making contact with the base. We also used plantogram and a special foam to measure foot size pressure and force as well as pressure and force that is appearing between the foot and the surface. In this work, we compared pressure between normal and deformed men and female foot against their body weight. With this analysis, we found that deformed foot makes bigger pressure on heel spur. In this research, we had 10 male and 10 female candidates. We were measuring weight, height and foot area as well as pressure and force that foot produce while walking. At the end, we concluded that the candidates with bigger body weight, made more pressure and force on their feet. We are hoping that this research will contribute in shoe factory to decrease weight on feet.
RESEARCH RESULTS OF DOSA-AGRO GRANULATOR WORKING PROCESS IN THE PRODUCTION LINES OF FUEL PELLETS
Authors: Sergeev Aleksandr
Published: May 2020

High heat content, renewability and low price of wood waste makes them a promising type of fuel. Production of fuel pellets enables transition to low-waste work of timber enterprises. The maximum productivity of pellet production line is primarily limited by the productivity of the granulator. The aim of the work is to identify the dependence of performance patterns of a press granulator with a DG series radial matrix in the production of fuel granules on the lignin content. The influence of the feedstock type and die diameter of the press granulator matrix on its performance has been evaluated. The granulator scheme and the principle of its operation are presented in the article. Doza-Agro LLC accumulated information on the operation of a press granulator with a radial matrix of the DG series as part of the production lines for the production of fuel pellets of the TP, TP-P and TP-S series operating in various regions of Russia. As a result of processing the accumulated information, an empirical equation is constructed. It describes the effect of the die matrix diameter and the lignin content in the raw material on the performance of press granulator. It has been revealed that its productivity is more affected by the lignin content. Its decrease in hardwood from 24% to 18% leads to a decrease in productivity by 20%, decrease in coniferous wood from 30% to 27% - by 15%. Reducing the diameter of the matrix die from 8 mm to 6 mm and lignin content from 26 to 20% reduces the granulator’s productivity by 32%.

A simplified diagram of a pneumatic energy-saving system for studying the functioning of the subsystems of accumulation and energy conversion of compressed air is presented. A mathematical model has been developed to evaluate the efficiency of using a pneumatic energy-saving system, which includes the equations of change in the gas state in its elements, solved by the Euler numerical method. A modeling algorithm is described, consisting of seven repeating steps performed in the process of computer simulation. The developed computer program is presented, which allows studying pneumatic energy-saving system. Computer experiments with the most typical set of its design and technological parameters are presented. The time dependences of the volume of the pneumatic cavities under consideration, the amount of substance in them, pressure and air temperature in the pneumatic cavities under consideration are obtained. The influence of the diameter of the pneumatic cylinder on the filling time of the receiver, the number of strokes of the piston and thermal efficiency has been defined
TESTS OF FIRE EXTINGUISHING ABILITY OF ALUMINUM HYDROGEL WHEN EXTINGUISHING MODEL NATURAL GROUND FIRES
Authors: Ivchenko Ol'ga , Pankin Kirill
Published: May 2020

Extinguishing natural fires largely depends on the effective use of fire extinguishers by firefighters. Nevertheless, there are objective limits to the fire extinguishing ability of known substances and materials, which cannot be overcome by either tactical or technological methods. In the work, a method for extinguishing ground fires using aluminum hydrogels with different concentrations as fire extinguishing compositions is proposed, which makes it possible to simultaneously realize three extinguishing methods: cooling, insulation, and combustion inhibition. Investigation of fire extinguishing ability of the selected fire extinguishing compositions has been carried out according to a specially developed technique that simulates formation and development of ground natural fire in experimental plots. Extinguishing efficiency was assessed by comparing the results of the total cost of extinguishing agents to a unit of length of the edge of the fire and a unit of area of the fire. It was shown that the best fire extinguishing ability has an aqueous solution of aluminum hydrogel with a concentration of 3.5-7 g/l. Fire extinguishing ability of aluminum hydrogels was investigated. The obtained results were compared with the fire extinguishing ability of water and aqueous solutions of sodium carbonate (soda) and sodium sulfate. The use of other aqueous solutions (soda and sodium sulfate) has not shown significant contribution to fire extinguishing. Therefore, fire extinguishing effect is completely due to the chemical composition and physical and chemical properties of aluminum hydrogel. Based on the data obtained, aluminum hydrogel costs per unit length and area of the fire, its lowest concentration, which retains the fire extinguishing effect and the technological conditions for its preparation and use, have been determined
UNDERGROWTH PHYTOMASS IN THE SECONDARY DECIDUOUS STANDS OF THE MIDDLE TAIGA
Authors: Pristova Tat'yana
Published: May 2020

The determination of organic matter reserves by forest phytocenoses is important in assessing biological produc-tivity of deciduous plantations formed at felling. As a rule, phytomass of the stand and soil cover is given when assess-ing forest productivity. This indicator is rarely determined for the undergrowth. The deciduous phytocenoses of the middle taiga, formed at the cutting of spruce of myrtillus type, have been studied. The undergrowth of the studied phy-tocenoses is represented by six species of woody plants: Salix caprea L., Sorbus aucuparia L., Rosa acicularis Lindl. and Lonicera pallasii Ledeb. Besides the mentioned species, Salix pentandra L. and S. philicifolia L are found in birch and spruce young growths. The method of “model trees” using allometric equations and the method of the “middle tree” for estimating the mass of individual species were used to determine the undergrowth phytomass. The specifics of the undergrowth phytomass dynamics in the studied after-cutting phytocenoses is associated with the overgrowing of felling by forest-forming and undergrowth species at the same time. It subsequently leads to competition between them. According to the studies in birch and spruce young forests, the undergrowth phytomass of decreased from 8.8 to 4.7 t/ha over 10 years; in aspen-birch stands - from 4.0 to 3.8. Throughout the entire studied period, fractions, accumulating organic matter (trunks and branches) for a long time, prevail in the undergrowth phytomass. The mass of leaves is 6-8% of the total undergrowth phytomass. The dynamics of the accumulation of organic matter by undergrowth is determined by biological characteristics of the species that form it, their abundance, natural thinning, and succession stage of the secondary stands.

Günümüzde, bulut teknolojileri endüstriyel alanlarda kullanılan cihaz ve makinelerden toplanan verilerin gerçek zamanlı olarak takip edilmesinde önemli çözümler sunmaktadırlar. Sahada elde edilen verilerin bulut platformlarına aktarılabilmesi için farklı türden ağ geçitlerinden yararlanılmaktadır. Bu çalışmada endüstriyel alanlarda kullanılabilecek düşük güç tüketimine sahip, düşük maliyetli nesnelerin interneti (Internet of Things, IoT) temelli bir ağ geçidi prototipi tasarımı sunulmaktadır. Bulut platforma aktarılacak verilerin sahadan ağ geçidi üzerine alınması için endüstriyel veri iletişiminde sıklıkla kullanılan Modbus protokolü kullanılmıştır. Ağ geçidinde toplanan verilerin bulut platformuna kablosuz ortamda aktarımını sağlamak için IoT uygulamalarında sıkça kullanılan Mesaj Kuyruk Telemetri Ulaştırma Protokolü (Message Queuing Telemetry Transport, MQTT) protokolü kullanılmıştır. Tasarlanan ağ geçidi, veriler üzerinde farklılığı algılayabilecek bir algoritma ile programlanmıştır. Verilerin hızlı bir şekilde görselleştirilmesi ve depolanması için IBM Watson IoT Platformu tercih edilmiştir. Ayrıca çalışmada tasarlanan ağ geçidinin performans analizi için MQTT sunucusu olarak Mosquitto kullanılmıştır. Deneysel test çalışmalarında, farklı boyutlarda yüklere sahip veri mesajlarının farklı seviyelerde servis kalitesinde (Quality of Service, QoS) uçtan uca gecikme süreleri ve istatistiksel sonuçları verilmiştir.
El Centro de Estudios del Museo Oteiza y su biblioteca
Authors: González Riera Borja
Published: May 2020

RESUMEN
Biblioteca y hemeroteca de la Fundación Museo Jorge Oteiza forman, con el archivo personal del escultor y escritor de Orio, la base del centro de documentación del museo. La biblioteca de Jorge Oteiza, como toda biblioteca personal, es clave para conocer sus intereses y para acercarse a su obra, y es testimonio de su amplio universo intelectual.
Una infinidad de anotaciones al margen, acotaciones y subrayados en sus libros y folletos, revistas y recortes de prensa, permite ahondar en sus reflexiones y en su pensamiento. La nueva biblioteca del museo se propone apoyar la investigación y el conocimiento de Jorge Oteiza, y es referencia obligada en la Comunidad Foral de Navarra en las áreas de escultura y arte contemporáneo.

LABURPENA
Jorge Oteiza Fundazio Museoaren liburutegiak eta hemerotekak osatzen dute, Orioko eskultore eta idazlearen artxibo pertsonalarekin batera, museoko dokumentazio zentroaren oinarria. Jorge Oteizaren liburutegia, liburutegi pertsonal oro bezala, giltzarria da haren interesak ezagutzeko eta haren obrara hurbiltzeko, eta haren unibertso intelektual zabalaren testigantza da. Liburu eta liburuxketan, aldizkarietan eta prentsa
ebakinetan egindako ezin konta ahala akotazio, azpimarratu eta alboko oharpenek aukera ematen dute haren gogoetetan eta pentsamenduan sakontzeko. Museoko liburutegi berriak Jorge Oteizari buruzko ikerketa eta ezagutza babestea du helburu, eta Nafarroako Foru Komunitatean nahitaezko erreferentzia da eskulturaren eta arte garaikidearen arloetan.

ABSTRACT
The library of the Fundación Museo Jorge Oteiza is along with the personal archives of the sculptor and writer from Orio, the base of the museum’s research centre. As any other personal library, it is a keystone to understand his interests and for a further approach to his sculpture works, and bears witness to his vast intelectual mind. An innumerable
amount of side notes and underlines stretch across pages and pages of his books and periodicals, allowing us to deepen into his thought. The new library’s aim is to provide support to researchers and widen our knowledge of Jorge Oteiza, his time and work, and is a must in the sculpture and contemporary art subjects among libraries in Navarra.
Biblioteca de la Ciudad de la Música

RESUMEN
Se trata de dar a conocer la Biblioteca de la Ciudad de la Música. Hacer un recorrido en el tiempo y mostrar cómo pasó de ser una sala en el conservatorio sin posibilidad de búsqueda, acceso, ni consulta, con un simple Excel como punto de partida, a tener un espacio digno con un catálogo informatizado de consulta pública. Cambio y avance propiciado por la gran decisión que se tomó en su día de darle vida y sentido, dotando de personal y recursos a una colección de sus características, especializada en música. Hecho producido gracias al trabajo e insistencia, durante largo tiempo, de muchas personas dentro de ambos conservatorios. Lo que ha derivado que hoy día sea lo que es, una biblioteca especializada en música, la única de Navarra.

LABURPENA
Helburua, Musikaren Hiriko Liburutegia ezagutaraztea da, denboran zehar ibilbide bat eginez, Excel xume bat besterik ez zuen kontserbatorioko gela bat izatetik, katalogo informatizatua duen kontsulta publikoko gune duina izatera nola pasatu den azalduz.
Musikan espezializatutako bilduma honi zentzua eta bizitza eman eta langile zein errekurtsoez hornitzeko hartutako erabakiak, aldaketa eta aurrerapauso hori erraztu zuten. Hau guztia, bi kontserbatorioetako pertsona askok luzaroan egindako lanari esker gauzatu da, egun Nafarroan dagoen musikan espezializatutako liburutegi bakarra sortuz.

ABSTRACT
The aim of this work is to promote the Library of the City of Music. Look back in time and show how it went from being a room in the conservatory without the possibility of searching, accessing or consulting, with a simple Excel sheet as a starting point, to have
a decent space with a computerised catalogue for public consultation. Change and progression came about by the big decision that was taken back in the day to bring to life and give meaning, provide staff and resources, to a collection of these characteristics, specialised in music. This happened thanks to the work and persistence for a long time
of many within both conservatories. Which has resulted in what it is today, a library specialised in music, the only one in Navarra.
