Emerging pollutants (EPs), also known as micropollutants, have been a major issue for the global population in recent years as a result of the potential threats they bring to the environment and human health. Pharmaceuticals and personal care products (PPCPs), antibiotics, and hormones that are used in great demand for health and cosmetic purposes have rapidly culminated in the emergence of environmental pollutants. EPs impact the environment in a variety of ways. EPs originate from animal or human sources, either directly discharged into waterbodies or slowly leached via soils. As a result, water quality will deteriorate, drinking water sources will be contaminated, and health issues will arise. Since drinking water treatment plants rely on water resources, the prevalence of this contamination in aquatic environments, particularly surface water, is a severe problem. The review looks into several related issues on EPs in water environment, including methods in removing EPs. Despite its benefits and downsides, the EPs treatment processes comprise several approaches such as physico-chemical, biological, and advanced oxidation processes. Nonetheless, one of the membrane-based filtration methods, ultrafiltration, is considered as one of the technologies that promises the best micropollutant removal in water. With interesting properties including a moderate operating manner and great selectivity, this treatment approach is more popular than conventional ones. This study presents a comprehensive summary of EP’s existence in the environment, its toxicological consequences on health, and potential removal and treatment strategies.
Hydropower Technology for Sustainable Energy Generation in Wastewater Systems: Learning from the Experience
Authors: Llácer-Iglesias Rosa M. , López-Jiménez P. Amparo , Pérez-Sánchez Modesto
Published: November 2021

Hydropower is a well-known technology, applied worldwide for electricity generation from renewable sources. Within the current framework, some studies have started to consider its application to existing urban water systems, to harness an excess of energy that otherwise would be wasted. This research sought to determine a methodology to assess the potential of hydropower application to wastewater treatment plants (WWTPs), regarding different aspects of sustainability. Firstly, previously developed methodologies for potential assessment in this sector at a country level were analyzed. Secondly, data from existing real case studies were gathered from publicly available documents and a theoretical analysis of their actual performance was conducted to validate assumptions made in the previous methodologies. As a result, the proposed new approach suggests adapting methodologies for potential assessment at a lower level, considering possible driving factors, other than economic feasibility. To define the study area, the management model scope should be considered. The power to determine the cut-off point for a WWTP to be considered as a potential site, is proposed to be lowered according to technical feasibility. Additionally, bearing in mind the sustainability concept, social or environmental factors should also be introduced in the methodology, tailored to the region being assessed. This novel perspective could provide a closer approach to the most likely decision-making level for these kinds of strategies in the wastewater industry.
The Effect of Multi-Years Reclaimed Water Irrigation on Dryland Carbon Sequestration in the North China Plain

Published: November 2021

Reclaimed water is an alternative water source which could alleviate the shortage of water resources in agricultural systems. Many researchers have studied the effect of reclaimed water on soil environment, crop yield, etc. However, carbon sequestration in reclaimed water irrigated agricultural systems is less studied. This study investigates methane uptake and photosynthesis in reclaimed water irrigation systems contributing to carbon sequestration estimation and analyzes the important factors impacting them. The results show that CH4 uptake is related to soil water-filled pore space (WFPS) with a quadratic and it has the highest uptake when WFPS is between 40 and 50%. Long-term reclaimed water irrigation could significantly decrease (p < 0.05) CH4 uptake and macroaggregate stability in the topsoil. However, reclaimed water had no significant impact on photosynthesis in comparison. The type of fertilizer is an important factor which impacts CH4 emission from soil; urea had a lower CH4 uptake and a higher CO2 emission than slow-released fertilizer. Overall, reclaimed water irrigation could effectively decrease soil carbon sequestration. A soil wetted proportion level of 40–50% was recommended in this study for favorable methane oxidation. Slow-released fertilizer in reclaimed water irrigated agriculture could better control soil carbon emission and soil carbon absorption.
Effect of Time-Resolution of Rainfall Data on Trend Estimation for Annual Maximum Depths with a Duration of 24 Hours
Authors: Morbidelli Renato , Saltalippi Carla , Dari Jacopo , Flammini Alessia
Published: November 2021

The main challenge of this paper is to demonstrate that one of the most frequently conducted analyses in the climate change field could be affected by significant errors, due to the use of rainfall data characterized by coarse time-resolution. In fact, in the scientific literature, there are many studies to verify the possible impacts of climate change on extreme rainfall, and particularly on annual maximum rainfall depths, Hd, characterized by duration d equal to 24 h, due to the significant length of the corresponding series. Typically, these studies do not specify the temporal aggregation, ta, of the rainfall data on which maxima rely, although it is well known that the use of rainfall data with coarse ta can lead to significant underestimates of Hd. The effect of ta on the estimation of trends in annual maximum depths with d = 24 h, Hd=24 h, over the last 100 years is examined. We have used a published series of Hd=24 h derived by long-term historical rainfall observations with various temporal aggregations, due to the progress of recording systems through time, at 39 representative meteorological stations located in an inland region of Central Italy. Then, by using a recently developed mathematical relation between average underestimation error and the ratio ta/d, each Hd=24 h value has been corrected. Successively, commonly used climatic trend tests based on different approaches, including least-squares linear trend analysis, Mann–Kendall, and Sen’s method, have been applied to the “uncorrected” and “corrected” series. The results show that the underestimation of Hd=24 h values with coarse ta plays a significant role in the analysis of the effects of climatic change on extreme rainfalls. Specifically, the correction of the Hd=24 h values can change the sign of the trend from positive to negative. Furthermore, it has been observed that the innovative Sen’s method (based on a graphical approach) is less sensitive to corrections of the Hd values than the least-squares linear trend and the Mann–Kendall method. In any case, the analysis of Hd series containing potentially underestimated values, especially when d = 24 h, can lead to misleading results. Therefore, before conducting any trend analysis, Hd values determined from rainfall data characterized by coarse temporal resolution should always be corrected.

Authors: Chen Han-Shen , Kuo Hung-Yu
Published: November 2021

To achieve the 2025 Non-Nuclear Homeland goal and carbon emission mitigation target, the Taiwan government has been developing actively green and renewable energy with low carbon emissions. This study assessed the FSPS development project in the Cigu region of Tainan City to provide a thorough analysis toward making tradeoffs among ecosystem conservation, aquaculture, fisheries, and green power generation development. This study employs the choice experiment method and designs different attributes and levels to discuss the preferences of stakeholders in the policy development choices for ecosystem conservation and FSPS. The hope is that it can balance economic development and ecological conservation. The findings demonstrate that the tourists’ marginal willingness to pay is low. The respondents then give importance to improving biodiversity. Finally, they prefer minimal changes to the status quo with the FSPS policy implementation. These findings can serve as a reference for decision making for regional sustainable development, aquaculture and fishery upgradation, and green power generation and exploitation.
Time-Delayed Bioreactor Model of Phenol and Cresol Mixture Degradation with Interaction Kinetics
Authors: Borisov Milen , Dimitrova Neli , Zlateva Plamena
Published: November 2021

This paper is devoted to a mathematical model for phenol and p-cresol mixture degradation in a continuously stirred bioreactor. The biomass specific growth rate is presented as sum kinetics with interaction parameters (SKIP). A discrete time delay is introduced and incorporated into the biomass growth response. These two aspects—the mutual influence of the two substrates and the natural biological time delay in the biomass growth rate—are new in the scientific literature concerning bioreactor (chemostat) models. The equilibrium points of the model are determined and their local asymptotic stability as well as the occurrence of local Hopf bifurcations are studied in dependence on the delay parameter. The existence and uniqueness of positive solutions are established, and the global stabilizability of the model dynamics is proved for certain values of the delay. Numerical simulations illustrate the global behavior of the model solutions as well as the transient oscillations as a result of the Hopf bifurcation. The performed theoretical analysis and computer simulations can be successfully used to better understand the biodegradation dynamics of the chemical compounds in the bioreactor and to predict and control the system behavior in real life conditions.
Fish Assemblages in Seagrass (Zostera marina L.) Meadows and Mussel Reefs (Mytilus edulis): Implications for Coastal Fisheries, Restoration and Marine Spatial Planning

Published: November 2021

Seagrass meadows and mussel reefs provide favorable habitats for many fish species, but few studies have compared the associated fish assemblages directly and examined the influence of environmental variables. Knowledge of fish assemblages associated with disparate habitats is needed for the conservation of coastal fisheries and marine spatial planning. Catch per unit effort data derived from fyke nets showed similar species richness and diversity in seagrass meadows and mussel reefs, suggesting that both habitats support elevated marine biodiversity of mobile fauna. However, it was shown that fish assemblage structure differed between those habitats, and also fish abundance in seagrass meadows was significantly higher than in mussel reefs by comparing the data with a multivariate extension of Generalized Linear Models (GLM). Furthermore, employing underwater video recordings to compare fish abundances in high and low water current speed mussel reefs with a Generalized Linear Mixed Model with negative binomial distribution, data revealed similar fish abundances (in terms of the MaxN metric) despite the variation in current speed, probably because the mussel formations provide sufficient shelter, even from high water currents. The commercially important species Atlantic cod (G. morhua), however, was significantly more abundant in the low water current mussel reef. Therefore, restoration efforts targeting G. morhua could benefit from restoring low current mussel reefs. Our study provides input for the conservation of coastal recreational and commercial fisheries, habitat restoration and marine spatial planning where certain habitats may be prioritized.

Published: November 2021

Frontline workers are instrumental in bridging the gap in the utilization of maternal health services. We performed a qualitative cross-sectional study with medical officers, accredited social health activists (ASHA), and auxiliary nurse midwifes (ANM), across 13 districts of India, in order to understand the barriers and enablers, at the system and population levels, for improving access of adolescents and mothers to services. The data were collected by means of in-depth interviews (IDI) with medical officers and focus group discussions (FGD) with ASHA and ANM in 2016. The interview guide was based on the conceptual framework of WHO health interventions to decrease maternal morbidity. Content analysis was performed. In total, 532 frontline workers participated in 52 FGD and 52 medical officers in IDI. Adolescent clinics seemed nonexistent in most places; however, services were provided, such as counselling, iron tablets, or sanitary pads. Frontline workers perceived limited awareness and access to facilities among women for antenatal care. There were challenges in receiving the cash under maternity benefit schemes. Mothers-in-law and husbands were major influencers in women’s access to health services. Adolescent clinics and antenatal or postnatal care visits should be seen as windows of opportunities for approaching adolescents and women with good quality services.

Published: November 2021

Key Points

Despite significant collateral effects on kidney transplant recipients during the early COVID-19 pandemic, mortality remained unchanged.

Considerable temporary reductions in admissions are safe, whereas reducing immunosuppression results in increased allograft rejection risk.

Background

Collateral effects and consequences of the coronavirus disease 19 (COVID-19) pandemic on kidney transplant recipients remain widely unknown.

Methods

This retrospective cohort study examined changes in admission rates, incidences of diseases leading to hospitalization, in-patient procedures, and maintenance medication in long-term kidney transplant recipients with functioning graft during the early COVID-19 pandemic in Germany. Data were derived from a nationwide health insurance database. Analysis was performed from March 15 to September 30 and compared the years 2019 and 2020. Effects on mortality and adverse allograft events were compared with COVID-19-attributed effects.

Results

A total of 7725 patients were included in the final analysis. Admissions declined in 2020 by 17%, with the main dip during a 3-month lockdown (–31%) but without a subsequent rebound. Incidences for hospitalization did not increase for any investigated disease entities, whereas decreasing trends were noted for non-COVID-19 pulmonary and urogenital infections (incidence rate ratio 0.8, 95% CI, 0.62 to 1.03, and 0.82, 95% CI, 0.65 to 1.04, respectively). Non-COVID-19 hospital stays were 0.6 days shorter (P=0.03) and not complicated by increased dialysis, ventilation, or intensive care treatment rates. In-hospital and 90-day mortality remained stable. Incidences of severe COVID-19 requiring hospitalization was 0.09 per 1000 patient-days, and in-hospital mortality was 9%. A third (31%) of patients with calcineurin-inhibitor medication and without being hospitalized for COVID-19 reduced doses by at least 25%, which was associated with an increased allograft rejection risk (adjusted hazard ratio 1.29, 95% CI, 1.02 to 1.63). COVID-19 caused 17% of all deaths but had no significant association with allograft rejections. All-cause mortality remained stable (incidence rate ratio 1.15, 95% CI, 0.91 to 1.46), also when restricting analysis to patients with no or outpatient-treated COVID-19 (0.97, 95% CI, 0.76 to 1.25).

Conclusion

Despite significant collateral effects, mortality remained unchanged during the early COVID-19 pandemic. Considerable temporary reductions in admissions are safe, whereas reducing immunosuppression results in increased allograft rejection risk.

Authors: Manaqib Muhammad , Fauziah Irma , Hartati Eti
Published: November 2021

This study developed a model for the spread of COVID-19 disease using the SIR model which was added by a health mask and quarantine for infected individuals. The population is divided into six subpopulations, namely the subpopulation susceptible without a health mask, susceptible using a health mask, infected without using a health mask, infected using a health mask, quarantine for infected individuals, and the subpopulation to recover. The results obtained two equilibrium points, namely the disease-free equilibrium point and the endemic equilibrium point, and the basic reproduction number (R0). The existence of a disease-free equilibrium point is unconditional, whereas an endemic equilibrium point exists if the basic reproduction number is more than one. Stability analysis of the local asymptotically stable disease-free equilibrium point when the basic reproduction number is less than one. Furthermore, numerical simulations are carried out to provide a geometric picture related to the results that have been analyzed. The results of numerical simulations support the results of the analysis obtained. Finally, the sensitivity analysis of the basic reproduction numbers carried out obtained four parameters that dominantly affect the basic reproduction number, namely the rate of contact of susceptible individuals with infection, the rate of health mask use, the rate of health mask release, and the rate of quarantine for infected individuals.

This study aimed to use charcoal derived from the bamboo and melaleuca produced by traditional kiln applied to sandy soil growing mustard green (Brassica juncea L.). The charcoals were applied at three ratio (1%,2%, and 3%, which correspond to 10, 20, and 30 g charcoal/kg soil in pots) and the control treatment without charcoal. Soil properties were investigated including bulk density, pH, electrical conductivity (EC), cation exchange capacity (CEC), organic matter content, total nitrogen, and total phosphorous. The results showed that bulk density decreased in charcoal-treated soils. pH and EC were in the suitable range for plants.Nutrients and CEC of the soil in the charcoal treatment were significantly higher compared with the control (CEC increase 6.8% to 16%; TC increase 80% to 115%; TN increase 37.5 to 75%). Green mustard growing on charcoalamended soil had greater height (higher 3% to 21%), bigger leaves, and higher yield (increase18% to 81%) than those of plants groomed in the control treatment. This study showed the potential of using charcoal as supplying nutrient to the poor soil. Moreover, the abundant of raw material and easy to produce, it is suitable for applying in the Mekong Delta, Viet Nam, and other countries with similar conditions and infrastructure.

Historic-geographical evolution of Bessarabia on the data of the old maps
Authors: Paskary Evgeniy , Herzen Andrey
Published: November 2021

Problems of research of the territorial development of the old-developed regions are due to the duration and extraordinary saturation of historical processes that flowed and continue in them. The study of changes in the territories of states and various entities is important not only for understanding the past: local and regional conflicts whose roots often go deep into centuries, remain for a long time and continue these days, territorial claims are relevant now. This is especially evident on the example of such regions of oldest development, as the Black Sea region.

Historic-cartographical studies, systematization of previously known and newly identified sources, the analysis of old geographical maps and plans allow us to form a holistic picture of the evolution of space, its territorial structure, as well as the functional role of one or another place in the past and present.

In the article on the example of Bessarabia—the historic-geographical region of the North-Western Black Sea coast—the most important cartographic works presented, being key for certain stages of its historic-geographical evolution and development of cartography as a whole: the Antiquity and the Middle Ages (when the first geographical maps appeared), the 15th–18th centuries (when the toponym under study was first applied into maps, and detailed topographic maps began to be created) and the 19th–20th centuries (when political events again changed the semantics of the toponym Bessarabia). It is shown how geographical representations of the region transformed during different historical periods. The content of the toponym denoting region is considered, at different times related to different sections of the Black Sea coast and included various territories, as well as its use today as a political tool reflecting actual territorial claims.

Ocean Waves in K-distributed Clutter
Authors: Bocquet Stephen
Published: November 2021

Two examples of low grazing angle radar sea
clutter, both well described by the compound K-distribution
model, are studied. Pulse Doppler processing is applied to obtain
two dimensional range-time textures for the intensity, centroid
and width of the Doppler spectrum. The first example exhibits a
monochromatic swell pattern, allowing phase averaging to be
applied to the textures. The second example has a more typical
ocean wave spectrum. The intensity textures are gamma
distributed, consistent with the compound K-distribution model,
but the Doppler spectrum centroid and width textures are also
found to be gamma distributed. Based on this analysis, a new
method for simulation of coherent radar sea clutter is proposed,
where separate memoryless nonlinear transformations are
applied to a simulated water surface to generate the spatially and
temporally varying intensity, centroid and width of the Doppler
spectrum. The method builds on the evolving Doppler spectrum
model for radar sea clutter simulation and established methods
for simulation of water surfaces.

At the end of the Middle Ages in Lombardy it was common for a rural lord and his subjects to be defined as friends. By comparing Lombardy to other areas of central and northern Italy, the essay underlines the exceptional nature of this situation, and questions its causes. Such a phenomenon had two main underlying reasons: on the one hand, the peculiar political relationship between city and countryside that distinguished Lombardy since the late thirteenth century; on the other hand, the strong consensual character of the Lombard lordship in the fourteenth and fifteenth centuries.

This study aims to describe the implementation of character values for students of SD Negeri 62 Palembang through the application of edutainment-based social studies learning media. This research uses a qualitative approach with descriptive methods. The subjects of this study were second grade students of SD Negeri 62 Palembang. The data collection techniques used in this study were observation and questionnaires and documentation. Edutainment-based learning media used is a game of guessing style. The character values observed when students played the style guess were cooperation, self-confidence, and discipline. Based on the results of observations made, this game is less effective if it is done on grade II students who are included in the low class, because when playing, many students still lack self-confidence.

Fiber and cocopeat are waste products from coconut husks that can be turned into value added products. Fiber and cocopeat from old coconut husks are well known in coconut industry in the world. This paper described fibre strength from young coconut husks, nutrient content and water-holding ability of young coconut cocopeat compared to old coconut cocopeat. The strength of fiber was determined by using Instron Universal Testing Machine. The results showed that mean load at break for young coconut fiber was 13.76 N while mean load at break for old coconut fiber was 14.93 N. Maximum tensile stress for young coconut fiber was 1.55 MPa and 1.76 MPa for old coconut fiber. The nutrient contents were determined for young cocopeat and old cocopeat resulted as phosphorus (372.79 ppm, 339 ppm), potassium (6829.68 ppm, 10040.46 ppm), calcium (508.74 ppm, 578.40 ppm), magnesium (468.67 ppm, 715.60 ppm) and sodium (1579.70 ppm, 3917.60 ppm). The pH value was 6.55 and 5.39 respectively. The ash contents were 2.62% for young cocopeat while 4.06% for old cocopeat. For water holding ability test, moisture content of each sample from young coconut cocopeat and old coconut cocopeat was determined by using soil moisture meter. After seven days with water added 500 ml two times/day, results showed that water holding ability for peat moss was the best while young cocopeat was better than the old cocopeat. All the results showed that fiber and cocopeat from young coconut husk have high potential for sustainable production in the coconut industry.

The functions performed by facility management practitioners and their classification have evolved over the last decades. The practice of Facility Management integrates many professions; however, certain authors have pointed out that heterogeneous views are generated by those responsible for the facilities and this has caused confusion about the understanding of the discipline in recent years. In addition, different attitudes about the discipline have been presented depending on the vision of the British or American schools of FM, which face the objectives and tasks throughout these years in different ways. This causes diffuse areas that prevent the identification of the entire spectrum of functions related to support activities in a facility management system. The objective of this research was to identify and classify the functions performed until the present time by facility managers in the literature to establish the scope of a facility management system. In this work, the authors carried out a review of the literature and an analysis of the different documents that gave rise to a proposal of the different functions performed and their classification into main areas. Later, a validation of the proposal was requested through an expert consultation in facility management in Latin America, which reached 94% approval. The validated proposal is composed of at least 37 functions performed by facility management professionals, and these functions can be classified into six main areas: Asset and Maintenance Management; Real Estate and Property Management; Energy and Sustainability Management; Corporate Project Management; Workplace Management; and Facilities Services Management.
