Land-Use and Climate Impacts on Plant–Pollinator Interactions and Pollination Services
Authors: Dalsgaard Bo
Published: April 2020

Most flowering plants rely on animals for pollination and most animal pollinators rely on flowering plants for food resources. However, there is an ongoing concern that anthropogenic-induced global change threatens the mutualistic association between plants and pollinators. Two of the most important factors of global change are land-use and climate change. Land-use and climate change may affect species distributions and species phenologies, leading to spatial and temporal mismatches between mutualistic partners. Land-use and climate change may also influence species abundances, nesting habitats, floral resources and the behaviors of pollinators. Thus, mutualistic plant–pollinator interactions should be more susceptible to global change than simple measures of biodiversity, such as species richness and species composition. The potential negative impacts of land-use and climate change on plant–pollinator interactions may have large consequences for the conservation of threatened plants and pollinators and economically by diminishing crop productivity. Here I highlight ‘fruitful avenues’ for research into better understanding the influence of land-use and climate change on plant–pollinator interactions.

Nailfold videocapillaroscopy (NVC) is an easy tool used for the assessment of patients with Raynaud’s phenomenon (RP) as possibly associated with systemic sclerosis (SSc). Recent insights have also highlighted its role in the diagnostic assessment of idiopathic inflammatory myopathies (IIMs). The aim of this study is to describe the diagnostic role of NVC in a series of 361 consecutive patients with interstitial lung disease (ILD). All the patients were assessed by clinical pulmonary and rheumatic examinations, blood exams, high-resolution computed tomography and NVC. NVC was considered positive only in the presence of avascular areas or giant capillaries, but also, the presence of bushy capillaries (BCs) was recorded. NVC was positive in 17.7% of ILD patients and in 78.1% of ILD patients associated with a diagnosis of connective tissue disease (CTD). In 25% of SSc-ILD patients, NVC proved necessary for a correct diagnosis. The presence of BCs and/or NVC positivity in ILD patients with normal levels of creatine phosphokinase is associated with amyopathic IIM, regardless the presence of RP. In conclusion, NVC is useful for the diagnostic assessment of incomplete forms of CTD and in amyopathic IIMs. NVC should be considered in the diagnostic assessment of ILD patients regardless of the presence of RP.

Published: April 2020

The land-use change is a major determinant influencing ecosystem carbon (C) patterns and nutrient cycling in subalpine forests in the Eastern Tibetan Plateau. While some results have been obtained in relation to the influence of land-use change on aboveground components, less is known about the belowground microbial communities and related processes. We assessed the structure and function of soil microbial communities following land-use change from old-growth forest (OF) to secondary forest (SF), plantation forest (PF), and grassland (GL) in the Eastern Tibetan Plateau, China. Phospholipid fatty acid profiles and enzyme activity analysis were used to determine the composition and activities of microbial communities, respectively. Significant differences in physicochemical characteristics, microbial communities, and extracellular enzyme activities in soils under different land uses were observed in this study. pH and total nitrogen (TN) in OF and SF were significantly higher than in GL. PF showed the highest soil organic C (SOC), and significantly higher than in GL. Total phosphorus (TP) and C/N ratio in PF were significantly higher than the other land-use types. OF and PF had significantly higher anaerobic bacteria than in GL. The actinobacteria in SF was significantly higher than in PF. The saprotrophic and ectomycorrhizal (SEM) fungi was significantly lower in GL than the other land-use types. Total microbial biomass and β-glucosidase activities were significantly higher in OF and SF than in GL. GL had significantly higher polyphenoloxidase activities than in OF and PF. Anaerobic bacteria, arbuscular mycorrhizal fungi and SEM fungi were positively correlated with SOC and TP, Gram+ bacteria were correlated with C/P and N/P ratio. N-acetylglucosaminidase activity was negatively correlated with anaerobic bacteria, while polyphenoloxidase activity was positively related to actinobacteria. Furthermore, redundancy analysis revealed that the microbial community composition was primarily regulated by TN and pH. This suggested that altered land-use type initiated changes in the physicochemical characteristics of the soils, which affected the composition of microbial communities and microbial enzyme activities related to nutrient cycling in this area. This provides a scientific basis for the influence mechanism of land use on composition and function of microbial communities, as well as the rational utilization and management of land resources.
Diversity and Function of Endo-Bacteria in Bursaphelenchus xylophilus from Pinus massoniana Lamb. in Different Regions
Authors: Fu Yan-Mei , Liu Hong-Bin , Wu Xiao-Qin
Published: April 2020

The pine wood nematode (PWN) Bursaphelenchus xylophilus is the pathogen that causes pine wilt disease (PWD), a devastating forest disease. PWN-associated bacteria may play a role in PWD. However, little is known about the endo-bacteria in PWN. We analyzed the diversity of endo-bacteria in nine isolates of PWNs from Pinus massoniana Lamb. in nine epidemic areas from three Chinese provinces by high-throughput sequencing of 16S rDNA and isolated and identified culturable endo-bacteria through construction of a 16S rDNA phylogenetic tree and Biolog microbial identification. We also examined the effects of endo-bacteria on PWN fecundity, antioxidant capacity, and virulence using sterile nematodes as a control. While the dominant endo-bacteria in PWNs from different regions exhibited no significant difference in the classification levels of class and genus, their proportions differed. Pseudomonas and Stenotrophomonas were highly abundant in all PWN isolates. A total of 15 endo-bacterial strains were successfully isolated and identified as six species: Stenotrophomonas maltophilia, Pseudomonas fluorescens, Kocuria palustris, Microbacterium testaceum, Rhizobium radiobacter, and Leifsonia aquatica. We also found that P. fluorescens significantly increased the egg production of PWN, and that both P. fluorescens and S. maltophilia enhanced the mobility of PWN under oxidative stress and reduced the content of reactive oxygen species by increasing antioxidant enzyme activity in PWN. These strains also accelerated the development of PWD, and P. fluorescens had a more beneficial effect on PWN than S. maltophilia. Diversity exists among the endo-bacteria in PWNs from different regions, and some endo-bacteria can promote PWN infestation by enhancing the fecundity and antioxidant capacity of the nematode. Our study contributes to clarifying the interaction between endo-bacteria and PWN.

Published: April 2020

A genetically engineered chimeric virus crTMV-CP-PLRV composed of the crucifer-infecting tobacco mosaic virus (crTMV) RNA and the potato leafroll virus (PLRV) coat protein (CP) was obtained by agroinfiltration of Nicotiana benthamiana with the binary vector pCambia-crTMV-CPPLRV. The significant levels of the chimeric virus enabled direct visualization of crTMV-CP-PLRV in the cell and to investigate the mechanism of the pathogenesis. Localization of the crTMV-CP-PLRV in plant cells was examined by immunoblot techniques, as well as light, and transmission electron microscopy. The chimera can transfer between vascular and nonvascular tissues. The chimeric virus inoculum is capable to infect N. benthamiana mechanically. The distinguishing feature of the chimeric virus, the RNA virus with the positive genome, was found to localize in the nucleolus. We also investigated the role of the N-terminal sequence of the PLRV P3 coat protein in the cellular localization of the virus. We believe that the gene of the PLRV CP can be substituted with genes from other challenging-to-study plant pathogens to produce other useful recombinant viruses.
Exploring West African Folk Narrative Texts Using Machine Learning
Authors: Lô Gossa , de Boer Victor , van Aart Chris J.
Published: April 2020

This paper examines how machine learning (ML) and natural language processing (NLP) can be used to identify, analyze, and generate West African folk tales. Two corpora of West African and Western European folk tales are compiled and used in three experiments on cross-cultural folk tale analysis. In the text generation experiment, two types of deep learning text generators are built and trained on the West African corpus. We show that although the texts range between semantic and syntactic coherence, each of them contains West African features. The second experiment further examines the distinction between the West African and Western European folk tales by comparing the performance of an LSTM (acc. 0.79) with a BoW classifier (acc. 0.93), indicating that the two corpora can be clearly distinguished in terms of vocabulary. An interactive t-SNE visualization of a hybrid classifier (acc. 0.85) highlights the culture-specific words for both. The third experiment describes an ML analysis of narrative structures. Classifiers trained on parts of folk tales according to the three-act structure are quite capable of distinguishing these parts (acc. 0.78). Common n-grams extracted from these parts not only underline cross-cultural distinctions in narrative structures, but also show the overlap between verbal and written West African narratives.

Published: April 2020

The surface roughness of the ground parts is an essential factor in the assessment of the grinding process, and a crucial criterion in choosing the dressing and grinding tools and parameters. Additionally, the surface roughness directly influences the functionality of the workpiece. The application of artificial intelligence in the prediction of complex results of machining processes, such as surface roughness and cutting forces has increasingly become popular. This paper deals with the design of the appropriate artificial neural network for the prediction of the ground surface roughness and grinding forces, through an individual integrated acoustic emission (AE) sensor in the machine tool. Two models were trained and tested. Once using only the grinding parameters, and another with both acoustic emission signals and grinding parameters as input data. The recorded AE-signal was pre-processed, amplified and denoised. The feedforward neural network was chosen for the modeling with Bayesian backpropagation, and the model was tested by various experiments with different grinding and neural network parameters. It was found that the predictions presented by the achieved network parameters model agreed well with the experimental results with a superb accuracy of 99 percent. The results also showed that the AE signals act as an additional input parameter in addition to the grinding parameters, and could significantly increase the efficiency of the neural network in predicting the grinding forces and the surface roughness.
Differentiation of the Mittag-Leffler Functions with Respect to Parameters in the Laplace Transform Approach
Authors: Apelblat Alexander
Published: April 2020

In this work, properties of one- or two-parameter Mittag-Leffler functions are derived using the Laplace transform approach. It is demonstrated that manipulations with the pair direct–inverse transform makes it far more easy than previous methods to derive known and new properties of the Mittag-Leffler functions. Moreover, it is shown that sums of infinite series of the Mittag-Leffler functions can be expressed as convolution integrals, while the derivatives of the Mittag-Leffler functions with respect to their parameters are expressible as double convolution integrals. The derivatives can also be obtained from integral representations of the Mittag-Leffler functions. On the other hand, direct differentiation of the Mittag-Leffler functions with respect to parameters produces an infinite power series, whose coefficients are quotients of the digamma and gamma functions. Closed forms of these series can be derived when the parameters are set to be integers.
Implications of Hepatitis E Virus in Blood Transfusions, Hemodialysis, and Solid Organ Transplants
Authors: Janahi Essam M. , Parkar Saba F. D. , Mustafa Sakina , Eisa Zaki M.
Published: April 2020

Hepatitis E Virus (HEV) is emerging as the primary cause of acute viral hepatitis in humans. The virus is commonly transmitted by the fecal–oral route via contaminated water in endemic regions or through the consumption of inadequately cooked swine products or game meats in industrialized regions. HEV genotypes 1 and 2 are predominantly associated with waterborne transmission in developing countries, whereas HEV3 and HEV4 are mainly zoonotically transmitted in industrialized countries. Seroprevalence in populations determined by detecting anti-HEV antibodies and serum HEV RNA is commonly used to analyze the presence of HEV. Although HEV RNA-based detection is now standardized, there is a lack of agreement between the assaying methods used for gathering seroprevalence data. Since 2004, HEV has been considered as a transmissible infectious agent through blood transfusion. Recent seroprevalence studies in European countries indicate an underestimated risk for blood transfusion and hence warrant testing the blood supply. HEV infection is usually self-limiting and spontaneously cleared. However, in about 60% of recipients of solid organ transplants, HEV progresses to chronic hepatitis. Immunosuppressive drugs such as tacrolimus are a major cause of chronic hepatitis and reducing its dosage results in viral clearance in about 30% of patients. In hemodialysis patients, the parenteral route is implicated as an important mechanism of transmission. In this review, we explore the clinical and epidemiological characteristics of various HEV genotypes in blood donors, hemodialysis patients, and transplant recipients.

Authors: Park Won-Jin , Park Jae-Hee , Shin Ho-Yong , Lee Jae-Ho
Published: April 2020

Background and Objectives: Telomeric zinc finger-associated protein (TZAP) is a telomere-associated factor that was previously called ZBTB48. This protein binds preferentially to long telomeres, competing with telomeric repeat factors 1 and 2. Genetic changes in TZAP may be associated with cancer pathogenesis; however, this relationship has not yet been elucidated for any type of cancer. In this study, we aimed to examine the clinicopathologic and prognostic value of TZAP expression in cervical cancer (CC). Materials and Methods: The data were extracted from The Cancer Genome Atlas cohorts by OncoLnc (21 cancer types, 7700 cancers). The prognostic value of TZAP for different stages of 264 CCs was examined using survival analysis. Results: The TZAP expression did not differ significantly between CC and normal matched tissues. Age, cancer stage, and viral infection were not associated with TZAP expression. Survival analysis revealed a shorter overall survival in CC patients with a lower TZAP expression (χ2 = 3.62, p = 0.057). The prognostic value of TZAP expression was greater in patients with N1 stage CC (χ2 = 5.64, p = 0.018). Conclusion: TZAP expression is a possible prognostic marker for CC, especially stage N1 CC.
A Design Approach of Porthole Die for Flow Balance in Extrusion of Complex Solid Aluminum Heatsink Profile with Large Variable Wall Thickness
Authors: Truong Tat-Tai , Hsu Quang-Cherng , Tong Van-Canh , Sheu Jinn-Jong
Published: April 2020

In this study, porthole die used for extrusion of a solid heatsink profile with wall thickness variation ratio up to 15.3 was designed using finite element (FE) simulations. To improve the flow balance in the die, a design approach was introduced to find the appropriate die structure, which includes the porthole and pocket geometry correction, the bearing length adjustment, and the port bridge structure modification. Using the proposed die, the predicted velocity relative difference (VRD) and the maximum velocity difference (ΔV) of extrudate were significantly lower than those of an initial die, which was preliminarily designed based on general design experiences. The required extrusion force and the residual stress in the product were also reduced significantly. Then, the effects of the port bridge structure and welding chamber height on the behavior of the metal flow in the die were investigated. To verify the proposed die design, experimental extrusions were conducted on a 930-ton extruder. The experiment results showed that the extruded product fulfilled the requirements for dimensional tolerances. The design approach presented in this paper can be useful for practical implementation of die design when extruding similar solid heatsink profiles with large wall thickness variation.

Published: April 2020

The micromolding process using biocompatible thermoplastic polymers is highly attractive as a fabrication process of microdevices in biomedical applications. In this study, we investigated the effect of the thermal history in the micromolding process on the crystallinity of semi-crystalline polymers, such as poly (L-lactic acid) (PLLA), during their crystallization from the amorphous and molten states. In particular, the thermal history in the micromolding process using poly(dimethylsiloxane) replica mold embedded with a thermocouple was recorded. The crystallinity of PLLA constructs fabricated using the micromolding process was measured via wide-angle X-ray scattering, and crystallization kinetics was analyzed based on the Kolmogorov–Johnson–Mehl–Avrami equation. A crystallization rate of k = 0.061 min−n was obtained in the micromolding process of PLLA crystallization from the amorphous state, accompanied by the quenching operation, forming a large number of crystal nuclei. Finally, the fabrication of PLLA microneedles was performed using micromolding processes with different thermal histories. The information about the thermal history during the micromolding process is significant in the development of polymer microdevices to achieve better material properties.
Effect of Mineralogy on the Beneficiation of REE from Heavy Mineral Sands: The Case of Nea Peramos, Kavala, Northern Greece

Published: April 2020

Beneficiation of a rare earth element (REE) ore from heavy mineral (HM) sands by particle size classification in conjunction with high-intensity magnetic separation (HIMS) was investigated. The HM sands of Nea Peramos, Kavala, Northern Greece, contain high concentrations of REE accommodated mainly in silicate minerals, such as allanite. However, the potential of the Northern Greek placer for REE exploitation has not been fully evaluated due to limited on-shore and off-shore exploration drilling data. Characterization of the magnetic separation fractions using XRD and bulk ICP-MS chemical analysis showed that the magnetic products at high intensities were strongly enriched in the light REE (LREE), relative to the non-magnetic fraction. Allanite and titanite are the major host mineral for REE in the magnetic products but mainly allanite controls the REE budget due its high concentration in LREE. SEM/EDS and ICP-MS analysis of the different particle size fractions showed LREE enrichment in the fractions −0.425 + 0.212 mm, and a maximum enrichment in the −0.425 + 0.300 mm. The maximum enrichment is achieved after magnetic separation of the particle size fractions. Mass balance calculations showed that the maximum REE recovery is achieved after magnetic separation of each particle size fraction separately, i.e., 92 wt.% La, 91 wt.% Ce, and 87 wt.% Nd. This new information can contribute to the optimization of beneficiation process to be applied for REE recovery from HM black sands.
Selenium Deficiency in Lymphedema and Lipedema—A Retrospective Cross-Sectional Study from a Specialized Clinic
Authors: Pfister Christina , Dawczynski Horst , Schingale Franz-Josef
Published: April 2020

Background: Selenium is a trace element, which is utilized by the human body in selenoproteins. Their main function is to reduce oxidative stress, which plays an important role in lymphedema and lipedema. In addition, selenium deficiency is associated with an impaired immune function. The aim of this study was to determine the prevalence of selenium deficiency in these conditions, and if it is associated with disease severity and an associated medical condition such as obesity. Methods: This cross-sectional study is an anonymized, retrospective analysis of clinical data that was routinely recorded in a clinic specialized in lymphology. The data was comprised from 791 patients during 2012–2019, in which the selenium status was determined as part of their treatment. Results: Selenium deficiency proved common in patients with lymphedema, lipedema, and lipo-lymphedema affecting 47.5% of the study population. Selenium levels were significantly lower in patients with obesity-related lymphedema compared to patients with cancer-related lymphedema (96.6 ± 18.0 μg/L vs. 105.1 ± 20.2 μg/L; p < 0.0001). Obesity was a risk factor for selenium deficiency in lymphedema (OR 2.19; 95% CI 1.49 to 3.21), but not in lipedema. Conclusions: In countries with low selenium supply, selenium deficiency is common, especially in lymphedema patients. Therefore, it would be sensible to check the selenium status in lymphedema patients, especially those with obesity, as the infection risk of lymphedema is already increased.

Authors: Krisbiantoro Philip Anggo , Kato Koki , Mahardiani Lina , Kamiya Yuichi
Published: April 2020

Since ammonia nitrogen is a pollutant causing eutrophication, it must be removed from wastewater to develop sustainable environment and society. Ozonation, which is an oxidation reaction with ozone, is an effective and efficient method for the removal of ammonia nitrogen in wastewater because the reaction can proceed at low temperature and atmospheric pressure. Although the researches in ozonation of ammonia nitrogen have been going on for the last five decades, the reaction mechanism has not yet been well understood and the papers focusing on the reaction mechanism are very few. In this short review paper, the progress in oxidation of ammonia nitrogen with ozone both in non-catalytic and catalytic reactions is summarized to provide a better understanding on the reaction mechanism for ozonation of ammonia nitrogen in water.

Published: April 2020

Crude oil spills pose a serious threat to the marine environment. This is due to crude oil, in large part, is composed of aromatic, aliphatic, and alicyclic hydrocarbons which are toxic, carcinogenic, and mutagenic to the marine life. However, the degradation of crude oil spills with bacteria in simulated seawater media is rarely reported. In this study, oil spill in the seawater, especially petroleum, had been successfully degraded by bacterium culture Bacillus subtilis in simulated seawater under 7 and 14 days incubation.  Simulated seawater had synthesized based on ASTM D1141-98 for Standard Practice for the Preparation of Substitute Ocean Water. The petroleum recovery was analyzed using Gas chromatography-mass spectrometry.  In this research, the optimum recovery value of crude oil degradation by the bacterial culture obtained by octadecadienoic acid compound gave a percentage recovery of 8.20% and 8.87% after 7 and 14 days of incubation, respectively. This result indicated that the B. subtilis culture has the ability to degrade crude oil spill in simulated sea water.

Authors: ŞEN Furkan , ZENGİN Nazmi
Published: April 2020

Background: Dyslipidemia is a disorder that refers to abnormal value of one or more lipid types in the blood lipid profile. Meibomian gland dysfunction (MGD) is the abnormal condition of meibomian gland secretion which contains lipid components. We aimed to show the relationship between dyslipidemia and the severity of meibomian gland dysfunction.Materials and Methods: A total of 64 participants who live in Konya were included in the study. Participants were divided into four groups regarded as grade 0 MGD (n=16), grade 1 MGD (n=16), grade 2 MGD (n=16), and grade 3 MGD (n=16). For each patient, the grade of MGD, blood lipid profile and Marx Line (ML) were evaluated.Results: The mean age of 48,39 (range 25-65) years, 61% (n=39) were women and 39 % (n=25) were men. All groups were similar in age (p = 0.666) and gender (p = 0.978). There was a statistically significant difference in triglyceride (TG) between groups (p=0,029) and there was a significant correlation between increasing level of triglyceride and increasing severity of stage of meibomian gland dysfunction (r=0,377). There was no statistically significant difference in other types of cholesterol between groups (p>0,05). Also, there was a statistically significant difference in width of the Marx Line between groups (p<0,05).Conclusions: According to our study, dyslipidemia with elevated serum triglyceride and total cholesterol levels, is associated with meibomian gland dysfunction. Meibomian gland dysfunction might give the information about the presence of dyslipidemia.

Trend Analysis and Forecasting of COVID-19 outbreak in India
Authors: Gupta Rajan , Pal Saibal K
Published: April 2020

COVID-19 is spreading really fast around the world. The current study describes the situation of the outbreak of this disease in India and predicts the number of cases expected to rise in India. The study also discusses the regional analysis of Indian states and presents the preparedness level of India in combating this outbreak. The study uses exploratory data analysis to report the current situation and uses time-series forecasting methods to predict the future trends. The data has been considered from the repository of John Hopkins University and covers up the time period from 30th January 2020 when the first case occurred in India till the end of 24th March 2020 when the Prime Minister of India declared a complete lockdown in the country for 21 days starting 25th March 2020. The major findings show that number of infected cases in India is rising quickly with the average infected cases per day rising from 10 to 73 from the first case to the 300th case. The current mortality rate for India stands around 1.9. Kerala and Maharashtra are the top two infected states in India with more than 100 infected cases reported in each state, respectively. A total of 25 states have reported at least one infected case, however only 8 of them have reported deaths due to COVID-19. The ARIMA model prediction shows that the infected cases in India may reach up to 700 thousands in next 30 days in worst case scenario while most optimistic scenario may restrict the numbers up to 1000-1200. Also, the average forecast by ARIMA model in next 30 days is around 7000 patients from the current numbers of 536. Based on the forecasting model by Holt’s linear trends, an expected 3 million people may get infected if control measures are not taken in the near future. This study will be useful for the key stakeholders like Government Officials and Medical Practitioners in assessing the trends for India and preparing a combat plan with stringent measures. Also, this study will be helpful for data scientists, statisticians, mathematicians and analytics professionals in predicting outbreak numbers with better accuracy.

The world is currently going through a disastrous event and a catastrophic upheaval caused by the coronavirus disease 2019 (COVID-19). The pandemic has resulted in loss of more than 150000 deaths across the globe. Originating from China and spreading across all continents within a short span of time, it has become a matter of international emergency. Different agencies are adopting diverse approaches to stop and spread of this viral disease but still now nothing confirmatory has come up. Due to lack of vaccines and proper therapeutic drugs, the disease is still spreading like wild fire without control. An Old but very promising method- the convalescent plasma therapy could be the key therapy to stop this pandemic. This method has already proven its mettle on several occasions previously and has been found to be effective in curing the pandemics induced by Ebola, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the same group of β-Coronavirus that has resulted in the above diseases. Therefore, the role of plasma therapy is being explored for treatment of this disease. In this review, we have mainly focused on the role of convalescent plasma therapy and why its use should be promoted in fight against COVID-19, as it could turn out to be a game changer.
3D printing, as a tool for planning orthopedic surgery
Authors: Cykowska-Błasiak Małgorzata , Ozga Paweł
Published: April 2020

The purpose of the literature review is to determine the scope of 3D printing, also known as RP (Rapid Prototyping) applications in manufacturing medical model based on CJP (Collor Jet Printing) technology, with emphasis on the use in orthopedic surgery planning. The research of the presented method will be focused on the financial aspect. Researchers accept as axiomatic fact that the main buyer of the MRP (Medical Rapid Prototyping) structure will be the patient while the recipient will be the doctor or surgeon that provides the operation.

Using available open-source software solutions and suitable method for the treatment of CT (Computed Tomography) scans based on filtering RAW files managed we to get the best or relatively good results allowing to exclude a human work from one of the most difficult and time-consuming processes. Total cost of 3D printings including all production processes and post-productions are about 50% lower than commercial rates (on free market) for the model of: “oscoxae” including "osfemoris" (femur length not exceeding 20 cm). In our opinion it’s "relatively positive" effect.

Despite the success in the field of lowering the cost of 3D prints our work is still focused on reducing it (at least up to another 30%) by using automated-machine processing and tasks automation, as well as using another printing methods. Using 3D printings as a tools to help plan complex orthopedic surgeries make possible to extremely reduce the time of using instrumentation and the treatment time (comparing to similar surgeries carried out without using 3D printings).
Evaluation of the decision maker's preferences in the selection means of transport
Authors: Duchaczek Artur
Published: April 2020

In the process of optimizing each criterion validity coefficients allow to take into account individual preferences of the decision maker. They are therefore one of its most important elements of this process. On the Polish market works very diverse range of vehicles. For the calculation of the validity coefficients for the optimization of the choice of means of transport used DEMATEL method. The application presented method resulted in a quantitative consideration of the actual decision-maker preferences based on fairly simple scientific method, and not only the intuition of the decision maker.

Authors: Życzyńska Anna , Cholewa Tomasz
Published: April 2020

Residential and public buildings use for heating more than 40% of the total energy consumption in the European Union. Therefore, this paper discusses the modifications to the building energy standard, which is currently in force. It is based on the requirements included in the Polish technical building regulations and standards. The proper energy-saving police have been implemented to this kind of consumers to diminish the energy consumption. The analysis pertains to the values of heat transfer coefficients of building partitions as well as the indexes of the energy demand for various types of buildings. The analysis was conducted between 1974 and 2013. Moreover; the changes within this range, which will come into force in 2014 and will continue to 2021, which act in accordance with the technical requirements suitable for buildings, were also discussed. Furthermore, minimal thicknesses of insulation materials which enable meeting this requirements of a heat transfer coefficient for building partitions, were examined in the article.

India being a populous country demanding construction on large scale. The change of environment since several years are more often generating seismic waves. Around 9 major earthquakes with magnitude scale of above 6 can be observed over an decade. The present study is to focus in increase in ductility without any earthquake resistance design but with inclusion of combination of fibers like nylon and sisal. Concrete due to its brittleness is very prone in case of seismic resistance alone. Reinforcing concrete with steel bars to strengthen the ductility was the traditional approach which is followed by all over the globe. The use of steel bars to strengthen a concrete beam is confined because of its limitation which causes sudden failure in concrete. Thus, making a concrete material which is more ductile than a normal concrete is basic aim of this experimental research work. T beam are casted to study their performance mainly due to know the behavior of column beam joint during seismic evaluation. The study shows the attributes of concrete due to inclusion of hybrid fibers and even generation of mathematical model to analyze the effect and variation of concrete properties due to inclusion of hybrid fibers. To study their seismic performance cyclic loading test is performed. An trial is made to increase ductility of concrete beams mainly near column beam joint which were very prone towards seismic waves by hybridizing sisal fiber and nylon fiber and can result in increase in ductility and load carrying capacity by 22% and 31% respectively in comparison with control specimen.
