Automobile Tire Assessment: A Multi-Criteria Approach
Authors: Ateekh-Ur-Rehman . , Alkahtani M.
Published: November 2020

In response to the present dynamic market, automobile manufacturing industries are constantly evaluating and improving their manufacturing strategies to stay competitive. It is also evident that they evaluate those strategies considering multiple criteria. In one such case, an automobile project manager has to ensure that the selected tire (among the available alternatives) complies with the prospective automobile’s performance. This paper presents an approach for the assessment of alternative automobile tires taking into account multiple criteria, such as tire sustainability, tire road performance, environmental issues, tire purchase cost and tire road grip. The presented approach is quite helpful to any decision maker who is interested not only in ranking alternatives but also in establishing the superiority of an alternative over others. The approach also helps to specify the position of each alternative with respect to ideal solution. A case illustration is used to demonstrate an application of the approach.

Published: November 2020

Increasing building construction raises concerns about construction and demolition (C&D) waste management. To assess this issue the building components, the collection schemes, their recycling and disposal should be investigated. In order to manage C&D wastes, paying attention to how this kind of wastes is disposed is imperative for their correct identification. Inattention, lack of organization and proper transport and sanitary disposal of construction and demolition waste lead to problems such as accumulation of construction waste in the streets. However, more than 90 percent of the potential for recycling and re-using as raw materials is provided. Environmental Protection Agency (EPA) has classified C&D wastes into three categories: non-dangerous waste, hazardous wastes and semi-hazardous wastes. Currently in Tehran, an average of about 50,000 tons per day of construction and demolition wastes are produced from which over 30,000 tons per day are dumped in landfills. According to this research more than 57% of these wastes are placed in the first category (non-dangerous waste) and have the potential for being recycled and reused. On the other hand, items that are placed in the second category shall be managed based on the existing laws. This article provides some management solutions including proposing methods for collecting and reusing construction waste in accordance with current market needs in Iran.
A Study of the Formation of Velocity Counter Lines and Secondary (Spiral) Flows in Different Cross Sections of Divergent, Convergent and Uniform Arcs
Authors: Liaghat A. , Tavanpour N.
Published: November 2020

The mechanical properties of flow are very complex in channel arcs. Therefore, dynamic numerical models of fluids are considered effective tools in predicting such flow fields. In this study, the numerical model was validated by the measures of a uniform U-shaped arc with a width of 0.6 meter. Then two similar U shaped arcs, divergent and convergent, were simulated by a three-dimensional numerical model with variable widths from 0.6 to 0.75 meters and 0.6 to 0.45 meters. Validating the numerical model by measured data in the uniform 180-degree arc showed that the model can simulate the flow field in the uniform arc very well. Results regarding several parameters such as rout of maximum velocity, maximum velocity line, water level variations, power of spiral flow, existence of a rotating cell are stated and discussed.

Authors: Abu Bakar B. H. , Noaman A. T. , Md. Akil H.
Published: November 2020

Concrete properties, such as toughness and ductility, are enhanced to resist different impacts or blast loads. Rubberized concrete, which could be considered a green material, is produced from recycled waste tires grinded into different crumb rubber particle sizes and mixed with concrete. In this study, the behavior of rubberized steel fiber-reinforced concrete is investigated. Flexural performance of concrete beams (400×100×100 mm) manufactured from plain, steel fiber, crumb rubber and combination crumb rubber and steel fiber are also evaluated. Similarly, concrete slabs (500×500×50 mm) are also tested under flexural loading. Flexural performance of the SFRRC mixtures was significantly enhanced. The toughness and maximum deflection of specimens with rubber were considerably improved. Steel fiber/crumb rubber-reinforced concrete can be used for practical application, which requires further studies.

Published: November 2020

Hydronic heating systems supplied by renewable energy sources are one of the main solutions for substituting fossil fuel and natural gas consumption. This paper presents the development of modeling and analysis of a solar hydronic heating system in an existing single-family house built in 1990’s heated by low-temperature radiators. The simulation has been used to study the potential of using this system under climatic conditions in Algeria. And for this purpose, a component based on the simulation model for the thermal behavior of each component of the system are carried out in order to evaluate the economic performance for this system. The system is compared, with a conventional high-temperature boiler system. The results indicated that single-family houses could be heated with solar hydronic heating and provided an acceptable level of thermal comfort in the room with 22°C, according to the results of the analysis, the solar energy covers only 20.8% of the total energy consumption in a single-family house. Furthermore, the thermal performance of the heating conventional system can be largely improved up to 15%.

Published: November 2020

Production of heavy crude oil in Mexico, and worldwide, is increasing which has led to the application of different methods to reduce viscosity or to enhance transport through stratified flow to continue using the existing infrastructures. In this context, injecting a viscosity improver that does not mix completely with the crude, establishes a liquid-liquid stratified flow. On the basis of a parallel plates model, comparing the increase of flow that occurs in the one-phase case which assumes a complete mixture between the crude and the viscosity improver against another stratified liquid-liquid (no mixing between the oil and compared improver); it was found that in both cases there is a flow increase for the same pressure drop with a maximum for the case in which the flow improver is between the plates and the crude.

Published: November 2020

The principles of health, safety and environment (HSE) in different development activities, including construction, are constantly gaining in significance. This study aims to evaluate the condition of HSE management and safety climate in construction sites. In this descriptive-analytic study, 111 male employees are randomly selected. To determine HSE condition and management and safety climate condition, the NOSACQ questionnaire was used. The collected data are analyzed using SPSS. Based on data analysis a significant relationship between the mean scores of safety climate, job groups and HSE management system with job groups, education and experience (P<0.05) was found. The study results show that HSE management and safety climate in sites are relatively acceptable, that the perception of safety had no special association with age, work experience, education and that the creation of a safety climate depends on the people high in the hierarchy.
Prediction of Springback in the Air Bending Process Using a Kriging Metamodel
Authors: Khadra F. A. , El-Morsy A. W.
Published: November 2020

This paper addresses the use of the kriging‏ approach to predict the springback in the air bending process. The materials and the geometrical parameters, which significantly affect the springback, were considered as inputs, and the springback angle was considered as the response. A verified nonlinear finite element model was used to generate the training data required to create the kriging‏ metamodel. The training examples were selected based on computer-generated D-optimal designs. A comparison between the kriging approaches and the response surface methodology is conducted and discussed. The results showed that kriging accurately predicts the finite element springback results. Comparing the accuracy of kriging with a response surface methodology shows that kriging with a 2nd degree polynomial and exponential correlation function predicts the springback more accurately than the response surface methodology.

Published: November 2020

The hetero junction operating as a solar cell is based on n GaAs p GaAs p Al0.75Ga0.25As. This paper investigates the influence of radiation electron ray on layers of hetero-junction AlGaAsGaAs. Long term operation in the radiation zone degrades solar cell power operating parameters and reduces overall cell’s life. The impact of radiation electron ray has been analyzed with various doses on layers of the AlGaAsGaAs hetero junction. V-A characteristics and parameters such as the photocurrent density (Jsc), voltage at open circuit (Voc) and energy conversion efficiency ( (η), are evaluated for different doses of electron radiations. It is shown that current and voltage decrease when irradiation doses increase. Further, Jsc and η parameters decrease proportionally to the increase of the electron radiation doses whereas Voc is only slightly decreased.

Published: November 2020

Given that the new product failure in practice entails huge costs for organizations, the need for competitive planning has led organizations to apply appropriate approaches; one of these approaches is to predict new product success before market entry. Accordingly, this study predicts NPD success by comparing two techniques, the Multilayer Perceptron (MLP) and the Radial Basis Function (RBF) in the clothing industry of Tabriz. In order to collect data, a questionnaire with good validity and reliability was distributed among the population. MLP and RBF were used to analyze data. Based on MSE, RMSE and R2, data analysis showed that MLP had lower error than RBF in predicting NPD success.

Authors: Mollamotalebi M. , Maghami R. , Ismail A. S.
Published: November 2020

Grid computing environments include heterogeneous resources shared by a large number of computers to handle data and process intensive applications. The required resources must be accessible for the grid applications on demand, which makes resource discovery a critical service. In recent years, different techniques are provided to index and discover grid resources. Response time and message load during the search process highly affect the efficiency of resource discovery. This paper proposes a technique to forward the queries based on the resource types accessible through each neighbor in super-peer-based grid resource discovery approaches. The proposed technique is simulated in GridSim and the experimental results indicated that it is able to reduce the response time and message load during the search process especially when the grid environment contains a large number of nodes.
A Numerical Proof of Concept for Thermal Flow Control
Authors: Dragan V.
Published: November 2020

In this paper computational fluid dynamics is used to provide a proof of concept for controlled flow separation using thermal wall interactions with the velocity boundary layer. A 3D case study is presented, using a transition modeling Shear Stress Transport turbulence model. The highly loaded single slot flap airfoil was chosen to be representative for a light aircraft and the flow conditions were modeled after a typical landing speed. In the baseline case, adiabatic walls were considered while in the separation control case, the top surface of the flaps was heated to 500 K. This heating lead to flow separation on the flaps and a significant alteration of the flow pattern across all the elements of the wing. The findings indicate that this control method has potential, with implications in both aeronautical as well as sports and civil engineering applications.

Abstract. Brazil's CH4 emissions over the period 2010–2018 were derived for the three main sectors of activity: anthropogenic, wetland and biomass burning. Our inverse modelling estimates were derived from GOSAT (Greenhouse gases Observing SATellite) satellite measurements of XCH4 combined with surface data from Ragged Point, Barbados, and the high-resolution regional atmospheric transport model NAME (Numerical Atmospheric-dispersion Modelling Environment). We find that Brazil's mean emissions over 2010–2018 are 33.6±3.6Tgyr-1, which are comprised of 19.0±2.6Tgyr-1 from anthropogenic (primarily related to agriculture and waste), 13.0±1.9Tgyr-1 from wetlands and 1.7±0.3Tgyr-1 from biomass burning sources. In addition, between the 2011–2013 and 2014–2018 periods, Brazil's mean emissions rose by 6.9±5.3Tgyr-1 and this increase may have contributed to the accelerated global methane growth rate observed during the latter period. We find that wetland emissions from the western Amazon increased during the start of the 2015–2016 El Niño by 3.7±2.7Tgyr-1 and this is likely driven by increased surface temperatures. We also find that our estimates of anthropogenic emissions are consistent with those reported by Brazil to the United Framework Convention on Climate Change. We show that satellite data are beneficial for constraining national-scale CH4 emissions, and, through a series of sensitivity studies and validation experiments using data not assimilated in the inversion, we demonstrate that (a) calibrated ground-based data are important to include alongside satellite data in a regional inversion and that (b) inversions must account for any offsets between the two data streams and their representations by models.

Abstract. The process of soil drying following a single rainfall input offers an integrated perspective on soil-vegetation water dynamics in responses to atmospheric conditions during periods without rainfall. In this work, the soil moisture dry-down time scale events (τ) was calculated using surface soil moisture data from the SMOS mission, with the objective to explore if the spatio-temporal variability of τ could be used as a proxy for regional flooding and waterlogging characterization. Our working hypothesis is that soil moisture dries up more slowly under flooded conditions as a result of slower surface water elimination by infiltration and capillary rise of water from the saturated zone close to the surface. A clear difference precipitation-moisture coupling was detected between two regions with different flooding dynamics. In a region where flooding is triggered by precipitation excesses on weekly-to-monthly time scales and where the coupling between precipitation and evapotranspiration is strong, a positive correlation between dry-down and 6-month accumulated precipitation anomaly was found for all seasons except winter. By contrast, in the other region where flooding is largely de-coupled from precipitation and evapotranspiration, but rather coupled to ground water table dynamics on time scales from several months to years, no significant correlations were found. These results are based on a short period of data: March 2010 – November 2014.

Abstract. Mining is one of the most important economic activities in Goiás, and it is necessary for the municipalities. The abundance of some mineral substances in the state makes Goiás a desirable location for large extraction companies. This research paper outlines that landscape alteration is inevitable, as it is necessary to remove natural areas for the exploitation of minerals. Agricultural areas could be effected by this process. This paper is discussing a evolution of mining activity that was done with the corporation of Alto Horizonte between 1985 and 2015, observing intervals of a decade, and relating this change to the socio-economic data of the municipality. Remote sensing techniques were used in conjunction with Geographic Information System (GIS), two such techniques include: satellite, image classification and data from socioeconomic surveys. Which provided the basis for relating them to the information generated by the mappings. Through quantitative analysis and visual observations of the mappings of the enterprise and its surroundings, it was possible to notice the modification of the landscape. In addition, socioeconomic data could indicate the influence that mining has had on Alto Horizonte. Although the enterprise has a high industrial mineral production and raise the city's GDP, it is not invested in better wages for the population, ie, workers' income does not keep up with the minimum wage increase.

Published: November 2020

Abstract. Remote sensing has become an important mean to assess crop areas, specially for the identification of crop types. Google Earth Engine (GEE) is a free platform that provides a large number of satellite images from different constellations. Moreover, GEE provides pixel-based classifiers, which are used for mapping agricultural areas. The objective of this work is to evaluate the performance of different classification algorithms such as Minimum Distance (MD), Random Forest (RF), Support Vector Machine (SVM), Classification and Regression Trees (CART) and Na¨ıve Bayes (NB) on an agricultural area in Tuscany (Italy). Four different scenarios were implemented in GEE combining different information such as optical and Synthetic Aperture Radar (SAR) data, indices and time series. Among the five classifiers used the best performers were RF and SVM. Integrating Sentinel-1 (S1) and Sentinel-2 (S2) slightly improves the classification in comparison to the only S2 image classifications. The use of time series substantially improves supervised classifications. The analysis carried out so far lays the foundation for the integration of time series of SAR and optical data.

Published: November 2020

Abstract. Restricted episodic changes occurred in a short time period and over large spatial extents. Extreme weather conditions usually give rise to restricted episodic changes. Sentinel-1 radar images of the Salar de Aguas Calientes in Chile acquired in the Altiplanic winter (March 2015 and June 2017), 2018 austral winter and 2017–2018 springtime, demonstrates the ability to monitor episodic events remotely. The results of the backscattered power are encouraging and show episodic variations in VV polarization at C-band. The surface features in Salar de Aguas Calientes Sur change in response to snowfalls during either the Altiplanic or austral winter with an increase of the backscattering in presence of dry snow over the salt pan crust. Flooding events related to snow-melting during spring 2017–2018 showed a decrease in the backscattering signal over ponded water and an increase when wind blows over the water. Remote-sensing observations of the salar can provide a means for monitoring changes in the surface of the salar and a better understanding of the associated climatic episodic event processes. Furthermore, it can help to have a better understanding of environmental changes in arid regions and the understanding of global climate change.

Abstract. The objective of this study was to verify the evolution of surface temperature associated with land use and land cover from 1985 to 2019 in Porto Alegre, RS, Brazil. The methodological procedures were performed in five steps: 1. Definition of the study area; 2. Land use and land cover classification from images of Landsat 5 satellite Thematic Mapper (TM) and Operational Land Imager (OLI) from Landsat 8 satellite; 3. Calculation of surface temperature from TM sensor band 6 and OLI sensor band 10; 4. Analysis of temperature evolution over the historical series; and 5. Temporal relation between surface temperature and land use and land cover classes. The results demonstrated that higher temperatures were associated to the evolution of two classes of land use and land cover: urban area and exposed soil, with the former occupying 31% in 1989 to 75% in 2018 of the study area. When comparing the first and last decade of the historical series for each season, there was an average increase of 4.18 °C in the surface temperature of the districts. Thus, adopting policies that mitigate the effects caused by densification and urban sprawl are necessary, mainly through the conservation of vegetated areas and water reservoirs, as these are crucial for the maintenance of air humidity and evapotranspiration.
OPTIMIZATION OF A RANDOM FOREST CLASSIFIER FOR BURNED AREA DETECTION IN CHILE USING SENTINEL-2 DATA
Authors: Roteta E. , Oliva P.
Published: November 2020

Abstract. Due to the high variability of biomes throughout the country, the classification of burned areas is a challenge. We calibrated a random forest classifier to account for all this variability and ensure an accurate classification of burned areas. The classifier was optimized in three steps, generating a version of the burned area product in each step. According to the visual assessment, the final version of the BA product is more accurate than the perimeters created by the Chilean National Forest Corporation, which overestimate large burned areas because it does not consider the inner unburned areas and, it omits some small burned areas. The total burned surface from January to March 2017 was 5,000 km2 in Chile, 20 % of it belonging to a single burned area in the Maule Region, and with 91 % of the total burned surface distributed in 6 adjacent regions of Central Chile.

Abstract. Urban forests are crucial for the population well-being and improvement of the quality of life. For example, they contribute to the rain damping and to the improvement of the local climate. Therefore a correct and accurate mapping of this resource is fundamental for its correct management. We investigated a method that combines machine learning and SLIC superpixel techniques using different Superpixels (k) number to map trees in the metropolitan region of the municipality of Campo Grande-MS, Brazil with aerial orthoimages with GSD (Ground Sample Distance) of 10 cm. The combination of superpixels and machine learning algorithms were checked out with a set of weka classifiers and achieved good results i.e. F-1 %98.2, MCC %88.4 and Accuracy of %96.8, supporting that this method is efficient when used for urban trees mapping.

Published: November 2020

Abstract. The data developed by the MapBiomas Amazon initiative ( http://amazonia.mapbiomas.org/ ) led by the Amazon Geo-referenced Socio-environmental Information Network’s (RAISG) is of unprecedented spatial and temporal resolution for the Andes region. It’s comprised by a series of annual maps for the years 2000 to 2017 that allow to monitor the extent of transformation in this region using a single regional methodological approach. Several variables were included to solve Andes-specific methodological challenges and they represent adaptations of RAISG’s Amazonian methodology to the Andean region. Among such, is the use of the novel NDFIb index (Turpo, 2018), an adaptation of the NDFI index that aims at mapping Andean Wetlands. Glaciers identification was aided by the fractional abundance of snow (Turpo, 2018), as well as small water bodies identification with McFeeters (1996) NDWI water index. This experience unfolds promising accessibility to novel land cover and land use regional reconstructions and comparisons possible only by the use of large-scale cloud-computing data processing tools, open source technology, spatially and temporally comprehensive remote sensing data, along with RAISG’s standardized protocols and frameworks.
FRAGMENTED OR COMPACT: THE CASE OF PERIURBAN MUNICIPALITIES IN THE NORTHWEST OF THE METROPOLITAN AREA OF BUENOS AIRES
Authors: Flores A. P. , Gaudiano M. E.
Published: November 2020

Abstract. The accelerated growth of cities since the middle of the last century occupies a prominent place in urban agendas. The development of planning strategies depends on the knowledge and understanding this phenomenon. Therefore, identifying the modification pattern in the spatial configuration is of paramount importance. In this sense, the high level of detail offered by remote sensing technologies makes it possible to estimate the distribution of human settlements and their relationship to other coverages. The information obtained allows to analyze spatial contiguity and general expansion but other indicators are needed to identify spatial singularities. This work aims to present a compaction indicator and fragmentation indicator, useful for identifying local configuration patterns and their temporal variation. The study area consists of the Moreno, Pilar, Gral Rodriguez, Luján and Mercedes municipalities of the metropolitan area of Buenos Aires (AMBA) for the period 1986–2019. The results indicate an increase in impervious surfaces higher than 300% in this period and the detection of new urban centres in those municipalities. In the future it is hoped to replicate the techniques presented throughout the AMBA in order to contribute to medium and long-term territorial planning.

Abstract. Aquaculture fish cages are usually located remote areas with poor accessibility. Synthetic Aperture Radar (SAR) is relevant to register and monitor their activity. However, in order to take advantage of the large amount of information this technology produce, it is necessary to develop automated tools of analysis. This work proposes an automated approach through an unsupervised polarimetric classification method using Sentinel 1 IW SLC Dual-Pol (VV + VH) products. An experimental evaluation was applied in Calbuco, an area with intense aquaculture activity in southern Chile. It was possible to demonstrate that this approach allows to improve the capacity of classification of previous experiences (86.49% user’s accuracy and 96.97% producer´s accuracy). Further studies are required to know the impact of wind speed on the classification as well as the spatial precision of the detection.

Published: November 2020

The agricultural sector is directly affected by climate variables. The presence of climate variability causes a considerable risk to agricultural productivities. Thus, risk management is an alternative to reduce risks, including optimizing the allocation of farmland and choosing crop insurance for a specific planting date. The purpose of this study is to investigate the agricultural risk management through risk measure of climate variability using the Conditional Value-at-Risk (CVaR) in rice production. This paper investigated several possible considerations of agricultural insurance premiums based on losses climate index. We concluded that the climate index insurance policy is the best choice that farmers can choose for each planting date, the higher the significance value considered, the more the value of Value-at-Risk and Conditional Value-at-Risk.

Background: Prolotherapy, as an alternative therapy, has emerged as an effective treatment for chronic musculoskeletal injury, including knee osteoarthritis (OA). Several studies have mention ozone as a potential treatment for these diseases, which is based on analgesic, anti-inflammatory, and anti-oxidant. Objectives: The current study aimed to investigate the effect of adding ozone gas to hypertonic dextrose and somatropin for knee prolotherapy in patients with knee OA. For this purpose, pain, knee stiffness, and physical activity are measured. Methods: Sixty patients with chronic knee OA were randomly assigned into two groups of DS and DSO. The DS group received intra-articular hypertonic dextrose (10 ml) plus 4 IU somatropin (4 IU), and the DSO group received 10 ml ozone 25 mcg plus intervention in the DS group. This procedure was performed three times (first, third, and fifth weeks). WOMAC score was examined during the third, fifth, and sixteenth weeks. Results: The mean WOMAC score of the DS group was decreased significantly (P < 0.001) sixteen weeks after providing the intervention (before 64.9 ± 10.6, vs. after 49.2 ± 9.0). A similar decrease (P < 0.001) was observed in the DSO group (before 64.1 ± 11.3, vs. after 41.3 ± 8.0). The decrease of the WOMAC score in the third and sixteenth weeks after providing the intervention was significant in the DSO group compared to the DS group (P < 0.005). Conclusions: For patients with knee OA, prolotherapy with ozone plus hypertonic dextrose and somatropin was more effective in sedating the pain and improving the stiffness and function of the knee than dextrose and somatropin alone.
Logic-Based Therapy and Consultation for Mentally Strong Women
Authors: Newhart Laura ,   National Philosophical Counseling Association
Published: November 2020

This paper explores the intersections between Elliot D. Cohen’s Logic-Based Therapy and Amy Morin’s "13 Things Mentally Strong Women Don’t Do" (HarperCollins 2019) with a focus on the ways that they shed light on and mutually support each other. With its six-step method (including the identification of Cardinal Fallacies, the refutation of those fallacies, the reinforcement of their corresponding Guiding Virtues, the use of Uplifting Philosophies, and the implementation of plans of action), Logic-Based Therapy and Consultation provides a systematic rational framework for understanding how our interpretation of facts and our opinions/value judgments about those facts interact in order to form habits, i.e., patterns of thoughts, feelings, and behavior, that can lead to a fulfilling or a not-so-fulfilling life. For its part, "13 Things that Mentally Strong Women Don’t Do" 1) helps us understand how these habits specifically affect women, 2) provides uplifting philosophies from a woman’s perspective, and 3) contributes to plans of actions by suggesting practical exercises for implementing these plans, all in order to help us develop those good habits or virtuous patterns of thought, feelings, and behavior that allow us to live our best lives.

Solidarity, Populism and COVID-19
Authors: Benjamin Andrew ,   DePaul University
Published: November 2020

The presence of COVID-19 has elicited a range of philosophical responses. The aim of this paper is to engage with the position advanced by Giorgio Agamben. Part of the critique of Agamben involves critique of populism. In response to populism the paper advances a different philosophical position this time ground in the concept of solidarity. The work of Hannah Arendt provides the basis for this response.

Liberating digital collections: Rights review of digital collections at the Ohio State University Libraries
Authors: Enimil Sandra Aya
Published: November 2020

Digital collections serve as one of the many vehicles for cultural heritage institutions to highlight and display digitized material from special and curated collections. Many institutions have long relied on fair use to make digitized content from their collections openly available online. In recent years, after researching collections, some institutions have specifically distinguished public domain content. These institutions took time and resources to enhance their digital collections with rights information. Reassessing and identifying rights status is worth the time and resources because providing this metadata allows visitors to make informed decisions about reuse.
Caring for our colleagues: Wellness and support strategies for remote library teams
Authors: Hudson-Vitale Cynthia , Waltz Rebecca Miller
Published: November 2020

The COVID-19 pandemic has posed many challenges for academic and research libraries and those working within them. Nearly everything that we do has been questioned and re-envisioned, and our days are filled with new work, uncertainty, and isolation.  Because of this, one of the areas that library leaders must invest in re-envisioning is how we can best support the well-being and morale of our library colleagues. This article identifies and discusses simple, informal, practical, and easy strategies that library leaders can use to support the physical, emotional, spiritual, professional, social, and mental well-being of their teams in remote and hybrid working environment.

Emicizumab in the treatment of hemophilia A
Authors: Tijanić Ivan , Golubović Ivana , Vučić Miodrag , Tijanić Miloš
Published: November 2020

Introduction: Despite substantial advances in the treatment of Hemophilia A with the use of concentrated factor VIII preparations during recent decades, bleeding episodes still occur from time to time. The development of inhibitors significantly reduces the efficacy of traditional replacement therapy, seriously increasing morbidity and mortality in these patients. Emicizumab (HEMLIBRA ®) is a chimeric bispecific humanized antibody that bridges activated FIX and FX and thus restores the function of missing activated FVIII. Aim: The aim of the study was to analyze the literature date of the effect of Emicizumab in the treatment of Hemophilia A. Results: Multicenter randomized studies called HAVEN have shown excellent results of this medication in the treatment of patients with Hemophilia A. FVIII inhibitors do not bind to or neutralize Emicizumab and therefore have no effect on the hemostatic activity of the drug. Emicizumab prophylaxis produced a significant reduction in treated bleedings of 79%, compared to with the group of patients on prophylaxis with bypassing agents, while the rate grew up to even 95% after longer observation. Other studies have also confirmed good treatment results and a favorable safety profile in both adults and children. In the cases of bleeding events or preparation for immediate surgical interventions, it is recommended to user FVII (NovoSeven) ® according to previous guidelines. Conclusion: The results of the prophylactic use of Emicizumabhave so far shown that it may be a revolutionary preparation that can significantly reduce bleeding episodes and improve the quality of life of patients with Hemophilia A. Nevertheless, further testing of this drug is required.

Published: November 2020

Introduction: Some of the typical skin diseases, such as Pemphigus vulgaris, Pemphigoid mucosae oris, Erythema exudativum multiforme, Sclerodremia, Dermatitis herpetiformis-Duhring and Lichen planus, can cause swelling and irritation in mucous membranes of the oral cavity. Aim: The aim of the study was to precise diagnosis and treatment of oral Lichen planus manifestations. Methods: Analyzing the literature data and the experience of clinicians, the most common oral lichen planus manifestations were investigated. Results: This disease most commonly occurs in middle-aged patients (30-60 years) and is more common in women than in men. Oral Lichen planus is rarely seen in children. The disease presents in 0.5% to 2% of the population. Clinical history established the relation between oral Lichen planus and oral carcinoma, and therefore this disease should be considered a precancerous lesion. Conclusion: Dermatoses in the mouth are localized most often in the oral mucosa, both at the height of the occlusal line and in the mucous membrane of the retromolar area, but they can also occur in the mucous membranes of the tongue, the floor of the mouth and lips.
