Assessing the Impacts of Climate Change and Land Use/Cover Change on Runoff Based on Improved Budyko Framework Models Considering Arbitrary Partition of the Impacts
Authors: Xiong Manling , Huang Ching-Sheng , Yang Tao
Published: June 2020

Various models based on Budyko framework, widely applied to quantify the impacts of climate change and land use/cover change (LUCC) on runoff, assumed a fixed partition used to distinguish the impacts. Several articles have applied a weighting factor describing arbitrary partitions for developing a total differential Budyko (TDB) model and a complementary Budyko (CB) model. This study introduces the weighting factor into a decomposition Budyko (DB) model and applies these three models to analyze runoff variation due to the impacts in the upper-midstream Heihe River basin. The Pettitt test is first applied to determine a change point of a time series expanded by the runoff coefficient. The cause for the change point is analyzed. Transition matrix is adopted to investigate factors of LUCC. Results suggest the consistency of the CB, TDB, and present DB models in estimating runoff variation due to the impacts. The existing DB model excluding the weighting factor overestimates the impact of climate change on runoff and underestimates the LUCC impact as compared with the present DB model. With two extreme values of the weighting factor, runoff decrease induced by LUCC falls in the range of 65.20%–66.42% predicted by the CB model, 65.01%–66.57% by the TDB model, and 64.83%–66.85% by the present DB model. The transition matrixes indicate the major factors of LUCC are climate warming in the upstream of the study area and cropping in the midstream. Our work provides researchers with a better understanding of runoff variation due to climate change and LUCC.

Published: June 2020

In the present study, the sorption behavior of iron (Fe) and manganese (Mn) from a binary metal solution system onto thermally activated natural zeolite was studied. Batch adsorption experiments were carried out to investigate the effects of zeolite quantity, particle size, and activation temperature. Equilibrium studies were carried out to evaluate the adsorption capacity of the thermally activated natural zeolite. The obtained results showed that the thermally activated natural zeolite favored the removal of Fe over Mn, due to competition between them. Elemental analysis of the activated zeolite samples obtained by energy-dispersive X-ray analysis (EDX) indicated a Si/Al ratio >4, which is specific for clinoptilolite-type zeolite. The removal of Fe and Mn was best described by the Langmuir model, indicating the formation of a monolayer on the surface of the activated natural zeolite. The kinetic results revealed that the experimental data were best fitted by the pseudo-second-order model for both metals. The results suggest that a new natural zeolite from Rupea quarry, Brașov County, Romania could be used as a potential adsorbent for removal of Fe and Mn from binary metal solution systems, addressing the lack of information about this material from this region.
A Framework for Planning and Evaluating the Role of Urban Stream Restoration for Improving Transportation Resilience to Extreme Rainfall Events
Authors: Doll Barbara A. , Kurki-Fox J. Jack , Line Daniel E.
Published: June 2020

Recent extreme rainfall events produced severe flooding across North Carolina’s Coastal Plain, revealing deep vulnerabilities in many communities. Climate change is expected to exacerbate these problems by further increasing rainfall intensity and the frequency of extreme rainfall events. Due to the risks posed by these changing rainfall patterns, a shift in the approach to infrastructure planning and management is needed for many floodprone communities, particularly in regard to managing streams and floodplains in urban areas. This study proposes a framework for systematically evaluating stream restoration in combination with engineered improvements to culvert and bridge crossings to identify and optimize options for mitigating extreme events in urban areas. To illustrate the methodology, extensive hydraulic modeling was conducted to test four different strategies for reducing flooding along a channelized and armored stream, Big Ditch, located in Goldsboro, North Carolina, USA. The results indicate that neither floodplain restoration nor infrastructure modification alone could alleviate flooding along Big Ditch. Rather, a combination approach would be required to mitigate flooding, which could result in substantial benefits for storms in excess of the 100-year event. The results suggest that shifting to a multi-faceted approach to improve resiliency to extreme events could improve public safety and reduce future damages due to flooding.

Published: June 2020

The ability to extract flood hazard settings in highly vulnerable areas like populated floodplains by using new computer algorithms and hydraulic modeling software is an important aspect of any flood mitigation efforts. In this framework, the 1D/2D hydraulic models, which were generated based on a Light Detection and Ranging (LiDAR) derivate Digital Elevation Model (DEM) and processed within Geographical Information Systems (GIS), can improve large-scale flood hazard maps accuracy. In this study, we developed the first flood vulnerability assessment for 1% (100-year) and 0.1% (1000-year) recurrence intervals within the Jijia floodplain (north-eastern Romania), based on 1D HEC-RAS hydraulic modeling and LiDAR derivate DEM with 0.5 m spatial resolution. The results were compared with official flood hazards maps developed for the same recurrence intervals by the hydrologists of National Administration “Romanian Waters” (NARW) based on MIKE SHE modeling software and a DEM with 2 m spatial resolutions. It was revealed that the 1D HEC-RAS provides a more realistic perspective about the possible flood threats within Jijia floodplain and improves the accuracy of the official flood hazard maps obtained according to Flood Directive 2007/60/EC.
Effect of Chloride Ions on the Point-of-Use Drinking Water Disinfection Performance of Porous Ceramic Media Embedded with Metallic Silver and Copper
Authors: Singh Rekha , Kim Woohang , Smith James A.
Published: June 2020

This study quantifies the effects of chloride ions on silver and copper release from porous ceramic cubes embedded with silver and copper and its effect on E. coli disinfection in drinking water. Log-reduction of E. coli by silver ions decreased after 4 h of contact time as the chloride ion concentration increased from 0 to 250 mg/L but, it was not changed by copper ions under the same conditions. For silver addition by silver-ceramic cubes, log reductions of E. coli decreased sharply from 7.2 to 1.6 after 12 h as the chloride concentration increased from 0 to 250 mg/L. For the silver-ceramic cube experiments, chloride ion also reduced the total silver concentration in solution. After 24 h, total silver concentrations in solution decreased from 61 µg/L to 20 µg/L for corresponding chloride ion concentrations. According to the MINTEQ equilibrium model analysis, the decrease in disinfection ability with silver embedded ceramic cubes could be the result of precipitation of silver ions as silver chloride. This suggests that AgCl was precipitating within the pore space of the ceramic. These results indicate that, although ionic silver is a highly effective disinfectant for E. coli, the presence of chloride ions can significantly reduce disinfection efficacy. For copper-ceramic cubes, log reductions of E. coli by copper embedded cubes increased from 1.2 to 1.5 when chloride ion concentration increased from 0 to 250 mg/L. Total copper concentrations in solution increased from 4 µg/L to 14 µg/L for corresponding chloride ion concentrations. These results point towards the synergistic effect of chloride ions on copper oxidation as an increased concentration of chloride enhances copper release.

Published: June 2020

As an essential factor of the earth’s critical zone, soil water has a remarkable influence on nutrient cycle and energy flow in terrestrial ecosystems and has attracted the attention of considerable scholars. Based on the online database of Web of Science, the bibliometric analysis was performed to evaluate the evolution feature of soil water research from 1934 to 2019. The results showed a rapid growth of scientific outputs with a gradually increasing proportion of internationally collaborative articles. Environmental Sciences, Water Resources, and Soil Science were the most frequently used subject categories, and the Journal of Hydrology had the highest number of publications in this field. The institutions from the USA and China were the most active, and the USA occupied a leading position in soil water research, producing the most articles and having the most considerable number of citations. Clusters of authors were mostly located in North America, Western Europe, West Asia, and East Asia. Keywords analysis demonstrated that climate change, drought, evapotranspiration, remote sensing, and irrigation were the current research hotspots. Scientific issues focusing on the interaction between soil water and environmental factors, drought forecast, relationships between soil structure and water/solute transport, improving the accuracy and depth of soil moisture monitoring with satellite, and spatio-temporal scaling transform require further research.

Published: June 2020

Biochar is generally available to absorb nitrogen, phosphorus and other pollutants to improve water quality. However, the feasibility of biochar in improving water quality deterioration after straw returning is still unclear. In this study, pot experiments were conducted to evaluate the effects of straw decomposition on total phosphorus (TP), ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3−-N) and potassium permanganate index (CODMn) under CK (no straw returning), ST (straw of 7 t/hm2 returning) and SC (straw of 7 t/hm2 and biochar of 20 t/hm2 returning) conditions. Results showed that straw returning could significantly increase the nitrogen and phosphorus contents in field water. After adding biochar, there were significant differences in TP, NH4+-N, NO3−-N and CODMn both in surface water and 0–10 cm soil water in SC treatment compared to ST treatment. The concentration of TP, NH4+-N, NO3−-N and CODMn in surface water under SC treatment were always lower than that under ST treatment, and the maximum concentration could decrease by 52.29%, 39.67%, 35.23% and 44.50%, respectively. In 0–10 cm soil water, the concentration of TP, NO3−-N and CODMn under SC treatment was always significantly higher than that under ST treatment, and the NH4+-N concentration in SC treatment was gradually higher than that under ST treatment at the middle-late observation period. Results indicate that straw returning combined with biochar can effectively decrease the nitrogen concentration, phosphorus concentration and organic pollutants in surface water, inhibit the diffusion of non-point source pollutant, and reduce the risk of water pollution caused by straw returning.

Published: June 2020

Understanding changes in precipitation extremes is critical for designing mitigation measures for the potential implications of a warming climate. This study assessed changes in the magnitude and frequency of precipitation extremes over Vietnam using high-quality gridded daily precipitation observations from 1980 to 2010. The annual maxima precipitation was analyzed to detect historical changes in the magnitude of precipitation extremes, while the number of heavy precipitation events, defined using the peak-over-threshold approach, was used to assess changes in the frequency of precipitation extremes. We found a strong signal of changes in the frequency of heavy precipitation, with 28.3% of Vietnam’s landmass exhibiting significant increasing trends. The magnitude of annual maxima precipitation shows a mixed pattern of changes, with less than 10% of Vietnam’s landmass exhibiting significant (both increasing and decreasing) trends. To identify possible mechanisms driving changes in precipitation, we assessed the relationship between inter-annual variations in precipitation extremes and climate variability represented by the teleconnection patterns of the Northern Hemisphere. Using five climate indices, we found that teleconnections across the Indian and Pacific Oceans have implied large control over the characteristics of precipitation extremes across Vietnam, with up to 30% of Vietnam’s landmass exhibiting a significant relationship.

Published: June 2020

At a former Danish polluted landfill, a field experiment using biofilters as an ex-situ remediation strategy for leachate water was carried out. The leachate water was polluted with phenoxy acids, mecoprop, dichlorprop, and their impurities originated from previous years of disposal of production wastes. Three individual biofilters were set up and each was filled with different a support material, e.g., sand, stonewool, and peat amended sand. The sand biofilter was spiked with ammonium acetate in pulses lasting a week to stimulate biomass growth and thereby enhance the removal of the phenoxy acids. The effects on removal and enantioselectivity were studied during a 69-day sampling campaign. Results showed that stimulation of the microbial community with ammonium acetate provided a boost, hence removal in the sand biofilter increased after the dosing whereas the stonewool and peat biofilters showed generally low removal. The highest removal was observed after stimulation in the sand biofilter for both herbicides. After a starting period, the removal was compound-specific but ranged from 60–100%. The final concentrations exceeded the drinking water limits slightly (0.25 µg L−1) (mecoprop and 2-(2/4-chlorophenoxy)propanoic acid), while it was considerably below the limit for all other compounds (2-(2-methylphenoxy)propanoic acid and dichlorprop). Enantioselective fractions were already 0.41, and 0.75 for mecoprop and dichlorprop, respectively, in the inlet, probably due to in-situ degradation in the landfill—Mecoprop showed some enrichment of the (R)-enantiomer in the sand biofilter whereas no real trends were seen in the stonewool and peat biofilter. Only minor alterations in enantiomeric fractions were observed for dichlorprop in all three biofilters. This experiment shows that it is feasible to remove micropollutants from landfill leachates and it is possible to stimulate biomass and thereby initiate and obtain increased removal faster.

Recharging the batteries by wireless energy facilitates the long-term running of the batteries, which will save numerous works of battery maintenance and replacement. Thus, harvesting energy form radio frequency (RF) waves has become the most promising solution for providing the micropower needed for wireless sensor applications, especially in a widely distributed 4G/5G wireless network. However, the current research on rectenna is mainly focused on the integrated antenna coupled with metal-insulator-metal tunneling diodes. Herein, by adopting the plasmon excitation of graphene and quantum tunneling process between graphene and GaAs or GaN, we demonstrated the feasibility of harvesting energy from the 915 MHz wireless source belonging to 5G in the FR1 range (450 MHz–6 GHz) which is also known as sub-6G. The generated current and voltage can be observed continuously, with the direction defined by the built-in field between graphene and GaAs and the incident electromagnetic waves treated as the quantum energy source. Under the RF illumination, the generated current increases rapidly and the value can reach in the order of 10

 A. The harvester can work under the multiple channel mode, harvesting energy simultaneously from different flows of wireless energy in the air. This research will open a new avenue for wireless harvesting by using the ultrafast process of quantum tunneling and unique physical properties of graphene.

Poder estructural agroalimentario en países emergentes. Algunas limitantes estructurales de la integración y cooperación internacional en materia agroalimentaria
Authors: Borrell Juan José
Published: June 2020

• Resumen El artículo formula un breve análisis del posicionamiento internacional de los países emergentes del Cono Sur, en particular de Argentina, a partir de las relaciones de integración y cooperación económica en materia agroalimentaria. Para tal fin se desarrolla el concepto de poder estructural agroalimentario en base a la noción de poder estructural de Susan Strange. Dicho enfoque a diferencia de la visión propuesta por el institucionalismo liberal de régimen alimentario, permite comprender la dinámica del sistema agroalimentario internacional en su real dimensión. El supuesto crítico que se plantea es que si bien la explotación de materias primas agroalimentarias ha generado coyunturalmente ganancias para las economías emergentes, el poder estructural agroalimentario a partir de relaciones de integración y cooperación de tipo asimétrico implica un posicionamiento periférico y dependiente en la economía global, viniendo en consecuencia a reforzar la configuración del poder estructural internacional.

Transformations of the transport system of the city of Lublin as a city-forming factor
Authors: Przesmycka Natalia
Published: June 2020

Lublin is an example of a medium-sized city, whose urban layout was shaped to a large extent by the conditions resulting from changes in the transport system. The very emergence of the city – initially as a settlement complex located on the neighbouring hills – was associated with the travel and trade routes of supra-regional importance crossing the Lublin region. The historical communication system is still visible in the urban structure of the city. The paper presents the most important transformations of the communication structure of the city of Lublin from the beginning of its existence to the 1920s. The next part will deal with issues from the years 1931-2016.

Sensory gardens are places designed to stimulate the senses. Most often they are designed near hospitals and schools, where due to availability of the garden, people suffering from sensory processing disorders (autism, dementia, depression) can enjoy new experiences in a safe and comfortable environment. The purpose of the study was to show the possibility of introducing a sensory garden also to the housing estate. The city of Krasnystaw is located 50 km south of Lublin. By carrying out an inventory of existing vegetation and study work, project guidelines were developed. One of the social aspects of the work was to create a garden, that is to integrate the residents. The plant material was selected having in mind senses specification, including hearing, smell and sight. Architectural elements (lighting, benches, gazebo) that were missing so far have been designed, using mainly natural materials – stone and wood. The project selected decorative species of trees and shrubs in terms of colors and forms of leaves, flowers, fruits and an interesting conformation.
Functionality of public spaces in historical urban layouts as based on Zamość and Lwów. Comparative analysis of selected components of city spaces in the context of the development and propagation/ promotion of Zamość and Lwów.
Authors: Kielin Katarzyna , Protsiv Yaryna
Published: June 2020

Development of cities sprouts from human potential. By limiting, restricting access to public spaces for people of every age, perceptive or motoric ability, the prospects of fruitful, inspirational encounter, forging friendship or fall in love become downrightly limited. Sameness is stagnant. Diversity brings to a city constant movement.  Polish Language Dictionary defines ‘’functionality’’ (‘’funkcjonalność’’) as ‘’useful, helpful, ergonomic, efficient’’ which in relation to public space design refers to sufficient space for approach and use, convenient dimensions, operational simplicity and precise purpose of the place. Cities such as Zamość, with clearly defined, planned urban structure, pose a great challenge to designers in terms of balancing innovative, practicable architectural facilities that would not interfere with historical substance of a world heritage monument. In other words, designing in a historical centre is like walking on thin ice with the risk of distorting the integrity and original outlook of the centre.

Zamość is a unique example of a Renaissance town designed at the end of the 16th century which retained its original urban/ communication layout, fortification system and a great amount of important buildings that combine both Italian and middle – European building practices.

Damage caused due to phishing attacks is that which targets the user's personal information. Phishing includes sending a user an email, or causing a phishing page to steal personal information from a user. Blacklist-based detection techniques can detect this form of attack; however, these approaches have certain limitations, and the number of people affecting have continued to grow. The aim of a technique for phishing detection using machine learning to identify each URL into either a legitimate URL or a phished URL. Data availability here in this proposed solution is the key to executing the solution and if there is any issue with data availability it can cost the project accuracy. Data used for model testing must be reliable and appropriate to almost identify all the websites that the user wants to check. Model consistency is another factor that may trigger project failure so the model has to be accurate in determining a true identity of URLs. This technique employs features of a standardized resource locator (URL). The features have been defined which contain URLs for the phishing site. The suggested approach employs certain characteristics to detect phishing. The strategy was tested with a data collection of 3,000 URLs for the phishing site and 3,000 valid URLs for the site. The findings show that more than 90 percent of phishing sites can be identified by the proposed technique.

Published: June 2020

The effect of the parameters of isothermal treatment at low temperatures, also called Austempering, on the impact toughness, hardness and microstructure of AISI 4340 steel was investigated. For this purpose, specimens for impact toughness tests were machined according to ASTM E 23-93a. For hardness tests, prismatic bars of 10mmx10mmx30 mm were manufactured. Austempering was performed in a salt bath furnace using 55% sodium nitrate and 45% potassium nitrate. Three temperatures: 300, 325 and 350 °C, and four soaking times: 1 min, 10 min, 1 hour and 10 hours, were used. Hardness tests were performed on Rockwell durometer and three indentations per sample on HRc scale were made. The impact toughness test was done with the Charpy method. The specimens, previously machined, were subjected to austempering, and then subjected to the respective tests. The maximum hardness value 56.75 HRC was found at 300 °C with 10 min of soaking time, and the maximum impact toughness value was 27.67 J, found under the same conditions. It was observed that the hardness and impact resistance are not always inversely related during Austempering. In all microstructure tests, a biphasic structure composed of lower bainite with lath martensite in different proportions was observed, showing that the bainitic reaction is never complete. it is concluded that when alloyed steels are subjected to the Austempering treatment, a decrease in hardness with the soaking time or variation in temperatura, is not always accompanied by an increase in impact toughness, since undissolved alloyed carbides can produce embrittlement at any time and temperature interval.

Skin Cancer is the most pervasive disease in the fair looking populace, and it is, for the most part, brought about by introduction to bright light. In this paper, a natural skin malignant growth order framework created, and the relationship of skin disease picture over the neural system concentrated with various sorts of pre-preparing. Skin Cancer influenced because of the remarkable development of skin cells. Those cells developed skin uncovered Sun. Skin malignancy gets diminished by dodging introduction to UV radiation. The Biopsy technique analyzes skin disease in the clinical field. A biopsy treated by expelling skin cells and those examples tried in the lab. This outcome sets aside an extended effort to be prepared. In this way, In this paper, we arranged a modernized programmed skin malignant growth discovery calculation utilizing Image preparing strategies. The gathered pictures from the informational index took care of into the framework, and it is prepared to characterize skin malignant growth. This strategy experiences preprocessing strategies for evacuating undesirable clamors in the picture—this highlights the photographs extricated utilizing the GLCM technique. The back propagation procedure causes us to gather the images into carcinogenic or non-dangerous.

The authors have attempted to create a model, based on actual experiments conducted on an oil fired Rotary Tilting Furnace of 200 kg melting capacity installed in a foundry unit of Agra. Multiple regression machine learning has been considered as a suitable and novel tool for Modeling of basic input process parameters of rotary tilting furnace. The basic process parameters in a rotary furnace considered are RPM (rotational speed per minute), Time of melting of one charge of 200 kgs (minute) ,melting rate of furnace (kg/hr) and fuel consumed for melting of one charge need to be controlled during whole process. In this paper the relation between input parameters such as rotational speed of the furnace, time, and melting rate have been attempted to be established with output parameter fuel consumption. This model of multiple regression machine learning may found its practical applicability in foundry industry to predict the fuel consumption of furnace before putting it in actual operation and accordingly the input parameters can be controlled for desired optimal fuel consumption. The methodology consists of experimental investigations, modeling of process parameters using machine learning, followed by result analysis. The fossil fuels may not last forever and till no other alternate fuels are developed for melting the foundry industry need to optimize it. The optimized results obtained by this model and computational technique are in line with the results of actual experiments.
