Mapping Cropland Abandonment in Mountainous Areas Using an Annual Land-Use Trajectory Approach
Authors: Song Wei
Published: October 2019

In recent years, with the unceasing acceleration of China’s urbanization and rapid development of the country’s economy, cropland abandonment has become an ongoing issue, especially in mountainous areas. Mapping abandoned cropland using remote sensing technology is still challenging due to the difficulties in distinguishing abandoned cropland from fallowed land. In addition, there are few credible approaches to map timing and recultivation of abandoned cropland. In this context, this research developed an annual land-use trajectory approach to map different types of abandoned cropland based on freely available Landsat and HJ-1 satellite images with a spatial resolution of 30 m. Based on this method, five types of cropland change, including one type of fallowed land and two types of abandoned land, were identified in a mountainous town of China (Zhongduo). In addition, the timing and recultivation of abandoned cropland were assessed. The accuracy of the abandonment map was assessed as high as 86.67%. It was found that the percentages of spontaneous abandoned, induced abandoned, fallowed, stable, and lost cropland in Zhongduo were 23.16%, 8.40%, 13.69%, 27.84%, and 26.91% from 2012 to 2017, respectively. The average time for spontaneously abandoned cropland was 3.45 years. Furthermore, 50.54% of the spontaneously abandoned cropland and 12.91% of induced abandoned cropland were recultivated due to fluctuating prices of agricultural products and materials, and the implemented land transfer policy.
The Naturalness of the Vistula Riverbank’s Landscape: Warsaw Inhabitants’ Perceptions
Authors: Wojnowska-Heciak Magdalena
Published: October 2019

This paper considers the issue of urban inhabitants’ appreciation of the naturalness of the landscape provided that people living in urban areas can benefit from the green space and would like to care more about its protection. This study examines: (1) Warsaw inhabitants’ preferences with regard to places to spend free time outdoors; (2) public perception of the advantages and disadvantages of the semi-natural Vistula riverfront; and (3) people’s connectedness to nature and willingness to donate funds to modernize the riverfront (N = 630). We applied a questionnaire method based on the computer-assisted web interview. The findings suggest that Warsaw residents appreciate the naturalness of the landscape at the Vistula riverfront, would not like to take direct responsibility for its condition, and would rather the municipality invest in public spaces. Therefore, the municipality of Warsaw should work to enhance inhabitants’ attachment to the place and build a sense of common responsibility for the protection of the riverfront’s natural environment.

Published: October 2019

The construction of hydropower stations is not without controversy as they have a certain degree of impact on the ecological environment. Moreover, the water footprint and its cumulative effects on the environment (The relationship between the degree of hydropower development and utilization in the basin and the environment) of the development and utilization of cascade hydropower stations are incompletely understood. In this paper, we calculate the evaporated water footprint (EWF, water evaporated from reservoirs) and the product water footprint of hydropower stations (PWF, water consumption per unit of electricity production), and the blue water scarcity (BWS, the ratio of the total blue water footprint to blue water availability) based on data from 19 selected hydropower stations in the Yalong River Basin, China. Results show that: (a) the EWFs in established, ongoing, proposed, and planning phases of 19 hydropower stations are 243, 123, 59, and 42 Mm3, respectively; (b) the PWF of 19 hydropower stations varies between 0.01 and 4.49 m3GJ−1, and the average PWF is 1.20 m3GJ−1. These values are quite small when compared with hydropower stations in other basins in the world, and the difference in PWF among different hydropower stations is mainly derived from energy efficiency factor; (c) all the BWS in the Yalong River Basin are below 100% (low blue water scarcity), in which the total blue water footprint is less than 20% of the natural flow, and environmental flow requirements are met. From the perspective of the water footprint method, the cumulative environmental effects of hydropower development and utilization in the Yalong River Basin will not affect the local environmental flow requirements.
Spatial Differences in China’s Population Aging and Influencing Factors: The Perspectives of Spatial Dependence and Spatial Heterogeneity
Authors: Wu Yuanyuan , Song Yuxiang , Yu Tingting
Published: October 2019

Since China became an aging society in 2000, the regional inequality of population aging has been highlighted, and the phenomenon of “aging before getting rich” has gradually become a core issue in China’s coordinated socioeconomic development. This paper aims to comprehensively assess the spatial differences and driving forces of China’s population aging through two-stage nested Theil decomposition, ESDA, and spatial econometric models. Empirical results show that spatial differences in population aging were evident at different spatial scales, and the distribution gradually decreased from east to west, showing a positive spatial correlation of similar value aggregation. Moreover, China’s population aging was determined by the demographic, socioeconomic, and natural environment, and there are different leading factors in different regions. The demographic aspects played a decisive role and had a direct influence, while the socioeconomic and natural environment indirectly affected population aging through demographic factors and became the root cause of regional differences in population aging. These findings provide an empirical basis for establishing a cooperative mechanism and formulating a targeted response to the problem of population aging in various regions in China.
The Factors Affecting the Environmental Practices of Companies: The Case of Serbia
Authors: Mijatovic Ivana , Maricic Milica , Horvat Ana
Published: October 2019

Environmental practices are often considered external to the business, and the impacts of self-regulation and other CSR company practices on environmental practices are important but not fully understood—especially in transitional and developing countries. The aim of this paper is to explore factors that influence the environmental practices of companies operating in Serbia. We observed four types of self-regulations (core values, codes of conduct, ISO 9001, and ISO 14001); the level of CSR practices in relationships with employees, customers, the local community, and society, and related to business transparency; as well as company features related to types of operations (manufacturing vs. service), size, and internationalization (multinational ownership and export activities). Based on the SEM analysis of data collected from 178 companies operating in Serbia, the findings showed that smaller, manufacturing companies that applied the observed types of self-regulations, which have a higher level of employee relations and are more social and community involved, are more likely to have higher levels of environmental practice. Among the observed self-regulation types, only ISO 14001 certification proved to have an individual effect on company environmental practices. However, our results also showed that the influence of core values, applied codes of conduct, and ISO 9001 certification cannot be neglected.
Risk Control Standard and Construction Control Technology of Shield Tunnel Passing through Irregular-Plate Bridge
Authors: Hu Yougang , He Ping
Published: October 2019

As a kind of statically-indeterminate point-support structure, the irregular-plate bridge (IPB) is extremely sensitive to the settlement of pier columns, and the stress of the plate is complicated. Because of the limitation of environmental conditions, the newly-built subway circular symmetric shield tunnel needs to pass the pier foundation of the IPB perpendicularly. To control the engineering risks, the pier settlement value must be known, and measures should be taken to reduce the settlement. This paper takes the project of the Beijing subway circular symmetric shield tunnels passing the existing IPB of the Guang’anmen Bridge as an example. First, the stress characteristics and settlement control standards of the IPB are analyzed, and then the technical scheme of synchronous jacking and key points of risk control during the construction of the shield passing the IPB are put forward. The relationship between the excavation face pressure of the shield tunnel and pier foundation settlement, and the ground settlement, are then analyzed. Finally, structural cracking after construction is analyzed, and the analysis shows that synchronous jacking technology can effectively control the settlement value of the subway tunnel passing the IPB. The technology is a feasible method for controlling the safety of a tunnel passing through a sensitive, statically-indeterminate bridge, and this work is a successful experience for similar major risk projects.

Authors: Appadu Appanah , İnan Bilge , Tijani Yusuf
Published: October 2019

In this paper, we construct four numerical methods to solve the Burgers–Huxley equation with specified initial and boundary conditions. The four methods are two novel versions of nonstandard finite difference schemes (NSFD1 and NSFD2), explicit exponential finite difference method (EEFDM) and fully implicit exponential finite difference method (FIEFDM). These two classes of numerical methods are popular in the mathematical biology community and it is the first time that such a comparison is made between nonstandard and exponential finite difference schemes. Moreover, the use of both nonstandard and exponential finite difference schemes are very new for the Burgers–Huxley equations. We considered eleven different combination for the parameters controlling diffusion, advection and reaction, which give rise to four different regimes. We obtained stability region or condition for positivity. The performances of the four methods are analysed by computing absolute errors, relative errors, L 1 and L ∞ errors and CPU time.
Renormalizable and Unitary Model of Quantum Gravity
Authors: Larin S. A.
Published: October 2019

We consider R + R 2 relativistic quantum gravity with the action where all possible terms quadratic in the curvature tensor are added to the Einstein-Hilbert term. This model was shown to be renormalizable in the work by K.S. Stelle. In this paper, we demonstrate that the R + R 2 model is also unitary contrary to the statements made in the literature, in particular in the work by Stelle. New expressions for the R + R 2 Lagrangian within dimensional regularization and the graviton propagator are derived. We demonstrate that the R + R 2 model is a good candidate for the fundamental quantum theory of gravity.

Published: October 2019

Mycotoxins are known worldwide as fungus-produced toxins that adulterate a wide heterogeneity of raw feed ingredients and final products. Consumption of mycotoxins-contaminated feed causes a plethora of harmful responses from acute toxicity to many persistent health disorders with lethal outcomes; such as mycotoxicosis when ingested by animals. Therefore, the main task for feed producers is to minimize the concentration of mycotoxin by applying different strategies aimed at minimizing the risk of mycotoxin effects on animals and human health. Once mycotoxins enter the production chain it is hard to eliminate or inactivate them. This paper examines the most recent findings on different processes and strategies for the reduction of toxicity of mycotoxins in animals. The review gives detailed information about the decontamination approaches to mitigate mycotoxin contamination of feedstuffs and compound feed, which could be implemented in practice.

Human influenza A(H2N2) viruses emerged in 1957 and were replaced by A(H3N2) viruses in 1968. The antigenicity of human H2N2 viruses has been tested by using ferret antisera or mouse and human monoclonal antibodies. Here, we examined the antigenicity of human H2N2 viruses by using human plasma samples obtained from 50 aged individuals who were born between 1928 and 1933 and from 33 younger adult individuals who were born after 1962. The aged individuals possessed higher neutralization titers against H2N2 viruses isolated in 1957 and 1963 than those against H2N2 viruses isolated in 1968, whereas the younger adults who were born between 1962 and 1968 possessed higher neutralization titers against H2N2 viruses isolated in 1963 than those against other H2N2 viruses. Antigenic cartography revealed the antigenic changes that occurred in human H2N2 viruses during circulation in humans for 11 years, as detected by ferret antisera. These results show that even though aged individuals were likely exposed to more recent H2N2 viruses that are antigenically distinct from the earlier H2N2 viruses, they did not possess high neutralizing antibody titers to the more recent viruses, suggesting immunological imprinting of these individuals with the first H2N2 viruses they encountered and that this immunological imprinting lasts for over 50 years.

Authors: Fránová Jana , Přibylová Jaroslava , Koloniuk Igor
Published: October 2019

Virus diseases of strawberry present several complex problems. More than 25 viruses have been described in the genus Fragaria thus far. Here, we describe a novel rhabdovirus, tentatively named strawberry virus 1 (StrV-1), that infects F. ananassa and F. vesca plants. Genomic sequences of three distinct StrV-1 genotypes co-infecting a single F. ananassa host were obtained using combined Illumina and Ion Proton high-throughput sequencing. StrV-1 was transmitted to herbaceous plants via Aphis fabae and A. ruborum, further mechanically transmitted to Nicotiana occidentalis 37B and sub-inoculated to N. benthamiana, N. benthamiana DCL2/4i, N. occidentalis 37B, and Physalis floridana plants. Irregular chlorotic sectors on leaf blades and the multiplication of calyx leaves seem to be the diagnostic symptoms for StrV-1 on indexed F. vesca clones. StrV-1 was detected in asymptomatic grafted plants and in 49 out of 159 field strawberry samples via RT-PCR followed by Sanger sequencing. The bacilliform shape of the virions, which have a cytoplasm-limited distribution, their size, and phylogenetic relationships support the assignment of StrV-1 to a distinct species of the genus Cytorhabdovirus. Acyrthosiphon malvae, A. fabae, and A. ruborum were shown to transmit StrV-1 under experimental conditions.

Published: October 2019

Intradermal (ID) immunization is of increasing interest due to the easy accessibility and excellent immunogenic properties of the skin. Among ID immunization methods, dissolving microneedles (MNs) have appeared as an alternative to traditional hypodermic immunization, offering many advantages, such as being an easily administered method, with no need for health personnel, painless, and avoiding the use of needles and sharp wastage. In this study, an affordable and easy-to-produce MNs method was developed based on aqueous blends of 30% w/w poly (methyl vinyl ether-co-maleic anhydride). As an antigen model, a subunit vaccine candidate based on outer membrane vesicles from Shigella flexneri was used. Both unloaded and antigen-loaded MNs were synthetized and characterized. The MNs were successfully validated in an in vitro Parafilm M® skin model and in a pig skin ex vivo model. Biodistribution studies were performed in BALB/c mice using 99mTcO4− radiolabeled samples. Results indicated that the vesicle vaccine was successfully released from the MNs and targeted gastrointestinal tract after 6 h post-administration. In vivo immunization and protection studies were performed in BALB/c mice. Mice were intradermally immunized through ear skin with one single dose of 200 μg antigenic complex, eliciting the production of specific systemic IgG and mucosal IgA. Moreover, MNs were able to protect mice from an experimental infection with 1×106 CFU/mouse of S. flexneri four weeks after immunization. This work demonstrates for the first time the potential of outer membrane vesicle-loaded dissolving MNs for ID vaccination against enteropathogens like Shigella.

Integrated Water Quality Governance and Sectoral Responsibility: The EU Water Framework Directive’s Impact on Agricultural Sector Policies in Norway
Authors: Hovik Sissel
Published: October 2019

In accordance with the EU Water Framework Directive (WFD), Norway has made the river basin the basis for coordination of sectoral policies. New units of River Basin Districts and Sub-Districts have been introduced. In each district, the joint water management plan and program of measures is formulated by cross-sector and multi-level networks. This network structure is added to and clearly subordinated to the primary structure following the sectoral principle and hierarchical steering. Therefore, the WFD objectives of good environmental status of all waters must be integrated into the goal structure and policy priorities of different sector authorities and levels of government. This paper examines whether and, if so, how the activities within the secondary structure of water governance influence the policies and practices of the agricultural sector regarding diffuse water pollution mitigation. The analyses of sector policy documents and water management plans reveal that even though the WFD’s aim of good ecological status of water is integrated into the objectives of the agricultural environmental program, only minor changes have been made in instrument targets and settings. Economic incentives and voluntary measures still dominate. This leads to the conclusion that the corporatist governance mode of the agriculture sector dominates the sector’s choice of policy objectives and instruments.

The dynamically developing construction of the Russian Federation makes it necessary to expand the range of alternative types of binders and materials based on them. Such binders include a composite gypsum binder used for the production of materials for various functional purposes. The manufacture and use of products based on composite gypsum binders is made possible by studying the Portland cement – gypsum – water system, the stability of which is ensured by introducing of an appropriate amount of active mineral additives. Such additives reduce the concentration of Са (ОН) 2 in the liquid phase of the hardening system and create the possibility of hardening under certain conditions without dangerous internal tensions. This article discusses the obtaining of effective cellular concrete on a composite gypsum binder. Cellular concrete surpasses some traditional materials in its structure, properties, methods of preparation, and they are universal in terms of operational properties. The possibility and expediency of using thin-ground concrete scrap as a mineral additive in the composition of composite gypsum binder for cellular concrete is established in the work. Thermal insulation and structural cellular concrete of D600 and D700 grades are obtained. It is revealed that the stepwise loading of the components of the concrete mixture with the initial introduction of a gypsum binder is rational.

Published: October 2019

The conservation of the environment is becoming a global concern for the use of fuels from fossil waste, and the production of biodiesel from renewable sources is being considered as an eco-friendly alternative since oleaginous organic waste presents potential as Energy condition An important aspect is to minimize the impacts generated by this waste under different conditions, and an operation related to the aspect is the elaboration and comparison of biodiesel obtained from residual frying oils with biodiesel produced with sunflower oil through the transesterification process based on ethanol. The evaluation was carried out on a laboratory scale with parameters and specifications found in the Peruvian Technical Standard for Biodiesel (NTP-321.12-200-2008), with the exception of water content, and the oxidative stability index (IEO). The following results were obtained 739.7 mg / kg and 1.5 hours and these do not meet the standards whose minimum reference corresponds to 500 mg / kg and 3 hours, respectively. The yield of residual oil and sunflower corresponds to 68.5% and 85.2% respectively. The research work establishes that the production of biodiesel from residual frying oil by the ethanol-based transesterification process is significantly less than the process with sunflower oilseeds, showing greater performance and stability.

Human eye is covered with mucous like thin membrane on the outer surface as well as inner surface of the eyelids. The thin membrane covering the outer surface is called as bulbar conjunctiva. Conjunctiva hyperemia refers to the redness of the conjunctiva. There are several reasons for this condition, some of which are related to pathologies like trauma, allergy, injury, prolonged use of lenses or glaucoma. Hence, it is one of the most vital parameter to diagnose these pathologies. For populous developing countries like India, ratio of ophthalmologist to citizen is highly skewed which negatively affects the public health. This gives rise to need for developing technology based solutions for initial screening of eye problems like conjunctiva hyperemia. This paper presents a framework for classifying normal versus red eyes using deep learning technique of convolution neural network (CNN). The model has shown promising results with 94% accuracy.

Cloud computing has led to the tremendous growth of IT organizations, which serves as the means of delivering services to large number of consumers globally, by providing anywhere, anytime easy access to resources and services. The primary concern over the increasing energy consumption by cloud data centers is mainly due to the massive emission of greenhouse gases, which contaminate the atmosphere and tend to worsen the environmental conditions. The major part of huge energy consumption comes from large servers, high speed storage devices and cooling equipment, present in cloud data centers. These serve as the basis for fulfilling the increasing need for computing resources. These in turn bestow additional cost of resources. The goal is to focus on energy savings through effective utilization of resources. This necessitates the need for developing a green-aware, energy-efficient framework for cloud data center networks. The Software Defined Networking (SDN) are chosen as they aid in studying the behaviour of networks from the overall perspective of software layer, rather than decisions from each individual device, as in case of conventional networks. The central objective of this paper is dedicated to survey on various existing SDN based energy efficient cloud data center networks.

In the past of years of development of digital communication and network communication technology with increase in transferring documents all over the world, the authenticity and ownership of document is also important and challenging to control. To solve these problems so many techniques evolved which comes under transform domain and spatial domain based watermarking techniques. Most commonly used popular digital image watermarking techniques based on Transform Domain are like Discrete Cosine Transformation (DCT), Discrete Fourier Transformation (DFT), Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD) transformations. But with lot of introduced techniques there must be a standard parameterized study required which compares them individually and explain their actual performance. In this paper, we implement watermarking using Transform Domain based techniques DCT, DWT and SVD and compare them practically on standard parameters like imperceptibility & robustness with use of standard attacks. For the analysis of them we take standard images for implementation of digital image watermarking. All work done in Matlab platform. Experimental result shows the performance quality of DCT, DWT and SVD based watermarking techniques with standard quality parameters.

With the advancement of technology and desire of Digitalization the sensitive data that are transmitted over the internet has to be secured. Since leakage of Information can lead to security theft, which happens in cybercrime. Hence securing the data which we share over the internet is almost as important in fulfilling the desire of digitalization. With this aim visual cryptography techniques are proposed. In the encryption phase of visual cryptography shares of secret data are created to transmit over the channel. And the shares are combined at the decryption phase to regain the original data. Considering one the existing method called RGB based multiple share creation with aid of Elliptical curve cryptography. The drawback of low PSNR value of retrieved image is boosted by adopting RSA in the second stage of encryption and proposed a Novel Visual cryptography Method that results in ∞ PSNR value along with retaining maximum information with PSNR in the retrieved data after attack.

The mobile system consist of two parts mobile tower and mobile phone .The radiation of phone depends upon range of signal. In daily usage of mobile phones it is observed that there is variation in the network range bar. Using this range bar of networks we need to study its effect on variation of tissue temperature of human beings. If range is full, radiation is low and vica-verca.Tower transmit signal that is received by mobile phone, signal strength is inversely proportional to square of distance. Radiation effect is more near to the tower and less far away from the tower. It is observed that the received power is more as compared with calculated power of the tower. Radiation absorption is also proportional to time. If range of the network is more the electric field intensity is less and goes on increasing if range becomes less. As range decreases radiation increase, temperature of the tissue increases. Temperature variation is from 0.47℃ to 4.1℃.In cancer treatment radiation therapy is used it is observed that as electric field intensity is increased penetration distance in the tissue will increase.

Indonesia as one of the countries in the world with internet users reaching 82 million people or around 30% of Indonesia's population, is currently entering the era of e-commerce. Conventional shopping culture is shifting to online shopping. Although Indonesian internet users have not all done online shopping (only 29% of people or 26.3 million of the total who have an internet connection, a Mars 2016 survey source), the e-commerce market potential is still very large. This was followed up by the increasing proliferation of e-commerce companies in the business world, both in large and small scale businesses. Millennial groups are increasingly recognized for their influence in the evolution of social media. Millennials are undeniably the biggest part of society who are familiar with digital devices such as cellphones and computers. Social researchers often classify generations born between the 1980s and 2000s as millennials. So it can be said that the millennial generation is the young generation today who are currently in the range of 15-34 years. In America millennials, 97% have computers, 94 have cell phones, and websites as news sources (Marketing Breakthrough Incorp., 2008). In Indonesia, studies and studies on millennial generation have not been done much, even though the total population of Indonesians aged between 15-34 years is currently very large, namely 34.45%. Millennia generation was researched because based on the Mars survey also mentioned that the largest online consumer in Indonesia aged 22-29 years. Therefore, millennials are undeniably the most important market of many products and services. Research evidence shows that millennial groups in finding information related to purchases refer to their friends and this information seeking behavior is facilitated by digital connections. Therefore the aim of this research is to gain a deeper understanding of millennial communication behavior towards purchases and their relationship to online consumer comments.

With the advent of the 21st century, the corporate world is facing several challenges and prospects that seems to be very arduous as well as stimulating. Firms and businesses throughout the world are in a necessity of upgrading their quality system and maintaining the product standards in order to survive. When a firm fails to have such a quality system, there will be a difficulty in identifying the issues. However, when an organization functions with proper procedures and system, the managers will easily find out the blockades as well as bring out the remedial and preventive activities. Therefore, the objective of the current study is examining the TQM and OP in manufacturing companies that are present in India. It was piloted in Indian manufacturing companies in Chennai with a sample size of 150 employees with the help of questionnaire method. The data that was gathered then evaluated using SPSS-AMOS. It was found that all the hypotheses were absolutely appropriate for the study and henceforth displayed the progressive influence of TQM on organizational performance (OP). It seemed that there was found no much variance in TQM and OP. Certain TQM practices are associated with OP of the Indian Firms. Lastly, the results offer a relevant knowledge about TQM from Indian manufacturing perspective TQM and OP was examined through Factor analysis (CFA), Reliability tests and SEM analysis. The Analysis revealed to what extent both TQM and OP are interrelated and in what way TQM practices brings an influence on OP of a firm.
