Existing Empirical Kinetic Models in Biochemical Methane Potential (BMP) Testing, Their Selection and Numerical Solution
Authors: Pererva Yehor , Miller Charles D. , Sims Ronald C.
Published: June 2020

Biochemical Methane Potential (BMP) tests are a crucial part of feasibility studies to estimate energy recovery opportunities from organic wastes and wastewater. Despite the large number of publications dedicated to BMP testing and numerous attempts to standardize procedures, there is no “one size fits all” mathematical model to describe biomethane formation kinetic precisely. Importantly, the kinetics models are utilized for treatability estimation and modeling processes for the purpose of scale-up. A numerical computation approach is a widely used method to determine model coefficients, as a replacement for the previously used linearization approach. However, it requires more information for each model and some range of coefficients to iterate through. This study considers existing empirical models used to describe biomethane formation process in BMP testing, clarifies model nomenclature, presents equations usable for numerical computation of kinetic parameters as piece-wise defined functions, defines the limits for model coefficients, and collects and analyzes criteria to evaluate and compare model goodness of fit.
Direct Membrane Filtration for Wastewater Treatment Using an Intermittent Rotating Hollow Fiber Module
Authors: Ruigómez Ignacio , González Enrique , Rodríguez-Gómez Luis , Vera Luisa
Published: June 2020

Direct membrane filtration of municipal wastewater has attracted a considerable interest in recent years. Preventing severe membrane fouling is a crucial issue in the process development. This paper aims to assess the effectiveness of a rotating hollow fiber module in enhancing fouling control. The effect of rotation speed, intermittence and permeate flux was studied in short-term tests at lab-scale. A combined filtration model considering residual fouling, intermediate pore blocking and cake filtration was used to analyze the effect of the shear induced by rotation. Results showed a significant flux improvement by increasing rotation shear stress and showed a nearly linear correlation between the threshold flux (ranged between 12 and 32 L·h−1·m−2) and the rotation speed. A proper rotation intermittence (10/15 on/off) was found, which may maintain a fouling control comparable to that achieved for continuous rotation. For a given energy demand, the optimal operating conditions involve high speeds (≥180 rev·min−1) with low to moderate intermittences. Analyzing the relative contribution of the different feedwater fractions on membrane fouling, colloidal particles and macromolecules were found to be the main contributors.

The excessive use of pesticides at different stages of crop production can pose a great danger to the aquatic environment, and particularly to fish. The purpose of the present work was to assess the negative effects of chlorpyrifos (CPF) on the liver histological architecture and the activities of marker enzymes in common carp (Cyprinus carpio Linnaeus, 1758), by applying a multi-biomarker technique. The tested insecticide is categorized as a priority pollutant in surface waters in terms of Directive 2013/39/EU. The carps were exposed to different and environmentally relevant CPF concentrations for 72 h (a short-term acute experiment). The results showed that the tested insecticide alters the liver histological structure, causing degenerative lesions, such as granular and vacuolar degeneration; necrobiotic alterations and necrosis, as well as changes in the circulatory system. In addition, CPF induces changes in the enzymatic activity of lactate dehydrogenase (LDH), aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), cholinesterase (ChE), glutathione peroxidase (GPx) and catalase (CAT). The results from such experimental set ups could be successfully used in the legislation related to the protection of water bodies from contamination, in areas with intensive application of plant protection products used in agricultural practices, and also in implementing the Water Frame Directive by using multi-biomarker approaches.
Managed Aquifer Recharge for Water Resilience
Authors: Dillon Peter , Fernández Escalante Enrique , Megdal Sharon B. , Massmann Gudrun
Published: June 2020

Managed aquifer recharge (MAR) is part of the palette of solutions to water shortage, water security, water quality decline, falling water tables, and endangered groundwater-dependent ecosystems. It can be the most economic, most benign, most resilient, and most socially acceptable solution, but frequently has not been implemented due to lack of awareness, inadequate knowledge of aquifers, immature perception of risk, and incomplete policies for integrated water management, including linking MAR with demand management. MAR can achieve much towards solving the myriad local water problems that have collectively been termed “the global water crisis”. This special issue strives to elucidate the effectiveness, benefits, constraints, limitations, and applicability of MAR, together with its scientific advances, to a wide variety of situations that have global relevance. This special issue was initiated by the International Association of Hydrogeologists Commission on Managing Aquifer Recharge to capture and extend from selected papers at the 10th International Symposium on Managed Aquifer Recharge (ISMAR10) held in Madrid, Spain, 20–24 May 2019.
Mass Balance of the Greenland Ice Sheet from GRACE and Surface Mass Balance Modelling
Authors: Zou Fang , Tenzer Robert , Fok Hok , Nichol Janet
Published: June 2020

The Greenland Ice Sheet (GrIS) is losing mass at a rate that represents a major contribution to global sea-level rise in recent decades. In this study, we use the Gravity Recovery and Climate Experiment (GRACE) data to retrieve the time series variations of the GrIS from April 2002 to June 2017. We also estimate the mass balance from the RACMO2.3 and ice discharge data in order to obtain a comparative analysis and cross-validation. A detailed analysis of long-term trend and seasonal and inter-annual changes in the GrIS is implemented by GRACE and surface mass balance (SMB) modeling. The results indicate a decrease of −267.77 ± 8.68 Gt/yr of the GrIS over the 16-year period. There is a rapid decline from 2002 to 2008, which accelerated from 2009 to 2012 before declining relatively slowly from 2013 to 2017. The mass change inland is significantly smaller than that detected along coastal regions, especially in the southeastern, southwestern, and northwestern regions. The mass balance estimates from GRACE and SMB minus ice discharge (SMB-D) are very consistent. The ice discharge manifests itself mostly as a long-term trend, whereas seasonal mass variations are largely attributed to surface mass processes. The GrIS mass changes are mostly attributed to mass loss during summer. Summer mass changes are highly correlated with climate changes.

Climate change is undoubtedly one of the world’s biggest challenges in the 21st century. Drought risk analysis, forecasting and assessment are facing rapid expansion, not only from theoretical but also practical points of view. Accurate monitoring, forecasting and comprehensive assessments are of the utmost importance for reliable drought-related decision-making. The framework of drought risk analysis provides a unified and coherent approach to solving inference and decision-making problems under uncertainty due to climate change, such as hydro-meteorological modeling, drought frequency estimation, hybrid models of forecasting and water resource management. This Special Issue will provide researchers with a summary of the latest drought research developments in order to identify and understand the profound impacts of climate change on drought risks and water resources. The ten peer-reviewed articles collected in this Special Issue present novel drought monitoring and forecasting approaches, unique methods for drought risk estimation and creative frameworks for environmental change assessment. These articles will serve as valuable references for future drought-related disaster mitigations, climate change interconnections and food productivity impacts.
Bed-Load Collision Sound Filtering through Separation of Pipe Hydrophone Frequency Bands
Authors: Choi Jong-Ho , Jun Kye-Won , Jang Chang-Deok
Published: June 2020

Bed-load discharge of a river can be monitored by indirectly measuring the acoustic pulses generated when the bed load collides with a steel pipe installed on the riverbed (i.e., pipe hydrophone measurement). However, existing methods used for filtering pulses from acoustic signals reflect a combination of bed-load collision frequency bands, thereby limiting characterization capabilities. This study proposes an improved filtering method that separates and efficiently examines frequency bands that are highly correlated with bed-load collision characteristics. Herein, an experimental hydraulic model and bed-load collision sound-measurement system were constructed, and bed-load collision experiments were repeatedly performed for collecting acoustic data using a pipe hydrophone. Fast Fourier Transform analysis was performed on data to select the specific frequency bands and pressures reflecting the bed-load particle size. Furthermore, a bandpass method to examine bed-load collision sounds is also presented herein. Results indicate that in comparison with existing filtering methods, the proposed bandpass method yields higher detection rates under bed-load conditions of low flow rate and small particle size, thereby demonstrating its enhanced effectiveness.

Authors: MEZHIN Vyacheslav S. , OBUKHOV Vladimir V.
Published: June 2020

During the lift-off and the ascent phase, spacecraft (SC) large-size attached equipment is impacted by intensive vibrations, largely due to acoustic pressures. To ensure a reliable in-orbit operation of all SC systems the modes of vibration loads shall be assessed as much as reliable (using experimentally-confirmed mathematical models). Determination of the vibroacoustic response parameters of the equipment structure is a very important issue for such equipment units (elements) which have a large surface square with a relatively small mass. Among such structures are folded solar arrays (SA) and reflector type antennae dishes (ART).
The purpose of this study is to validate the calculation methodology of vibration power spectral density (PSD) for low and medium frequency band (25-400 Hz), and apply it for the aforesaid structures in the lift-off and flight phases as part of the integrated launch vehicle in the area of maximum ram effects, when the acoustic pressure levels, and therefore their impact on the vibroacoustic response of these structures are maximum. The target goal has been implemented using the example of the solar array and reflector type antenna being used in the spacecraft power supply system and onboard radio system of one of RSC Energia-developed spacecraft.
Key words: environment air, spacecraft, solar array, reflector type antennae dish, dynamic model, sound pressure level, acoustic pressure, structure vibroacoustic response.

La crónica literaria y la comunicación de un saber a través del cuerpo y la voz
Authors: Moure Clelia
Published: June 2020

El artículo propone una lectura crítica de dos crónicas latinoamericanas contemporáneas: “Escrito en el cuerpo” de Josefina Licitra y “La esquina es mi corazón (o los New Kids del bloque)” de Pedro Lemebel. En ambos casos la crónica vehiculiza una experiencia de la historia, recuperando para la memoria colectiva historias minoritarias, excluidas del régimen de verdad de la “historia monumental” en términos de Nietzsche, y por lo tanto, ajenas a la circulación del saber. El “saber oficial”, que configura y controla la circulación de los discursos en las instituciones escolares, ha excluido –por sus propios imperativos epistemológicos– las historias minoritarias. En esta perspectiva crítica, el artículo postula la necesidad de hacer valer las crónicas como herramientas de comunicación de un saber que hace a la identidad de nuestros pueblos y que configura nuestra experiencia colectiva.

Higher Education Transformation has become a trend among colleges under the Ministry of Religious Affairs. The organizational readiness for change in status and function is not merely about an individual readiness, but the readiness of all of the organization. This research aimed at finding how high the readiness level in the transformation of STAKN Kupang to IAKN Kupang was. A quantitative approach was used by using a survey method. The questionnaire used was the Organizational Readiness for Implementing Change (ORIC) by Weiner which measures two dimensions of readiness named change efficacy and change commitment to face an organizational change. A sample of 50 people was taken out of the population of 200. The result of One Sample T-test shows tcount= 5,738, which compared to the value of ttable=0,67964. Since the t-count > t-table, H0 is accepted which means the readiness level in the institution transformation becoming IAKN Kupang is greater than or equals to 75% as expected (H0:m ≥ 75 %). Even though, STAKN Kupang is categorized into a high readiness level group, there are five factors to be considered in the future for the sake of its continuity and sustainability: organizational climate and culture, interpersonal relationship, leadership, past habit and mindset, and techonolgy implementation.  AbstrakTransformasi pendidikan tinggi di Indonesia telah menjadi tren di lingkup per-guruan tinggi di bawah Kementerian Agama.

Published: June 2020

In a study of fossil seeds recovered from the La Cantera Formation, Early Cretaceous, San Luis Basin, we establish a new species, Carpolithus volantus, and describe other specimens attributed to Carpolithus spp. and Ephedra canterata. The botanical affinity of winged seeds assigned to Carpolithus volantus is discussed in relation to the fossil flora recovered from this formation. Based on the abundance of Gnetales in the San Luis Basin (pollen grains, reproductive and vegetative structures assigned to Ephedra), we propose that Carpolithus volantus is affiliated with Gnetales (Weltwitschia). We suggest that Carpolithus spp. seeds may be angiospermous, because this group, represented by leaves and flowers, dominates the fossil macroflora of the La Cantera Formation. Micro- and macrofloral analyses of the La Cantera Formation and an assessment of available dispersal vectors suggests that wind (anemochory) and water (hydrochory) may have been the most important dispersal strategies for these seeds. The abundance and small size of seeds recovered from the La Cantera Formation, together with their morphological characters, such as the presence of wings in Carpolithus volantus, also favour abiotic mechanisms of dispersal such as anemochory or hydrochory.
Obesity of Population in the Voronezh Region: The Current Epidemiologic Situation
Authors: Mamchik NP , Gabbasova NV , Dzen NV , Kolnet IV
Published: June 2020

Background: Numerous studies have demonstrated a steadily growing trend in the prevalence of obesity
around the world. The objective of this study was to assess obesity incidence rates among various age groups of the
population of the Voronezh Region in 2010–2017. Materials and methods: We used official data of the Voronezh Regional
Information Fund, Registration Form No. 12 of the Russian Federal State Statistics Service, as well as outpatient cards
and medical histories of 685 adults and 269 adolescents. Results: We established that the number of obese adults prevailed.
The study period of 2010–2017 was characterized by a steady increase in the incidence and prevalence rates of
obesity across all age groups of the population: we observed a 1.5, 2.6 and 4.5-fold rise of the incidence rates in children,
adolescents and adults, respectively; the percent increase in the prevalence rates was slightly lower and amounted
to 34.51% in children, 70.09% in adolescents, and 146.50% in adults. The highest obesity rates were registered among
adolescents: 5.02% of them were obese and the study of a random sample confirmed the official statistics. At the same
time, the results of the random obesity study in adults demonstrated a tenfold excess of the registered rate. Ranking of
the territory of the Voronezh Region by obesity prevalence rates and the analysis of long-term average rates of increase
in overall morbidity over the study period showed uneven distribution of obesity by administrative districts of the
region in all population groups. Conclusions: The study demonstrated a pronounced upward trend in the incidence of

The research uncovers the value and uniqueness of the volumetric planning structure of the historical town of Lyashky Murovani, now known as Murovane Village, Staryi Sambir district in the Lviv region.

Within the town features of Baroque urban planning are found and characteristics of the historical urban development of the location are revealed. The current components of the volumetric and spatial composition of the former city are analysed. A reconstruction scheme of the 17th-century city planning structure was presented, when it consisted of a market square with residential buildings blocks, sacral objects, and a palace and park complex. The study also reveals that the urban object passed through several stages of reconstruction during its development. A fragmentary revitalization program of the historical town into a modern village of Murovane was proposed.

Background: Refractive error is the most common cause of correctable visual loss worldwide. Decreased vision due to refractive error can be easily corrected with the help of spectacles, contact lenses and refractive surgery. However, there are 42% of uncorrected refractive errors all over the world. The present study aimed to evaluate different kinds of refractive errors, its prevalence and pattern in patients from rural areas who visited our hospital in the last five years.

Material and Methods: This cross-sectional study enrolled 2,138 patients, who visited eye OPD at Rawal Institute of Health Sciences, Islamabad during a period of five years i.e. from September, 2013 to September, 2018. Patients having only refractive error with an age of five years and above were included in the study.  All patients had objective refraction with automated refractometer followed by subjective refraction. Data was entered and analyzed in SPSS version 20.0. Chi-square test was used for comparing groups with a P-value of <0.05 considered as statistically significant.

Results: Compound myopic astigmatism was the most common error found in our study population (n=575; 26.9%). The second most frequent complaint was simple myopia (n=501; 23.4%) followed by presbyopia (n=441; 20.6%) and mixed astigmatism (n=235; 11%). Patients with more than one refractive error included 178 (8.3%) with mixed astigmatism and presbyopia and 78 (3.6%) with simple myopia and presbyopia. Compound myopic astigmatism was more prevalent in younger ages compared to older age groups (46.4% vs 19.9%) (P <0.001). Mixed astigmatism (12.4% vs 8.9%), simple myopia (23.8% vs 22.9%) and presbyopia (21.3% vs 19.5%) were slightly greater in females than males (P=0.07), respectively.

Conclusions: The prevalence of myopia is significantly higher among female population and young individuals. Mixed astigmatism combined with presbyopia is more common among elderly population.
Diagnostic Accuracy of Sonographic Septations in Tuberculous and Malignant Pleural Effusions

Published: June 2020

Background: Discrimination between tuberculous (TB) and malignant pleural effusions is a real practical challenge because both exist as exudative lymphocytic type. Transthoracic ultrasonography not only identifies and quantifies pleural effusion but also displays sonographic septations, which are frequently seen in TB pleural effusions and can help in differentiation between tuberculosis and malignancy successfully, without any invasive procedure. We designed this study to determine the diagnostic usefulness of these septations for tuberculous and malignant pleural effusions.

Material and Methods: This prospective study was conducted in the OPD of Gulab Devi Chest Hospital Lahore, Pakistan, a 1500 bedded tertiary care hospital, from November 2016 to February 2018. Total of 339 consecutive cases, aged 14-83 years with radiological evidence of pleural effusion were included in the study. After detailed history, thorough physical examination, radiological, haematological and biochemical findings were recorded. Pleural fluid macroscopic, cytological, microbiologic and biochemical analysis results were also recorded. Ultrasonography was done, septated and non-septated pleural effusions identified and findings were noted. SPSS-16 was used for statistical evaluation. Fisher Exact test was utilized for comparison between TB and malignant cases with P-value < 0.05 taken as significant. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy and positive likelihood ratio were calculated.

Results: Out of total 339 cases, 49 (14.45%) were malignant and 290 (85.55%) were non-malignant. In the malignant group, only 03 cases (6.12%) showed sonographic septations. In the non-malignant group, 259/290 (89.31%) cases showed tuberculous etiology and 187/259 (72.20%) of these cases displayed sonographic septations. By considering septations as predictor of TB, statistical analysis revealed a sensitivity of 79.23%, specificity of 92.85%, PPV of 98.42%, NPV of 44.31% and diagnostic accuracy of 81.29%, respectively.

Conclusions: Sonographic septations can be a valuable predictor of tuberculosis, in a population with high prevalence of the disease. We found it to be a useful feature in differentiating between a malignant and tuberculous etiology, in exudative lymphocytic pleural effusions. It can be used with confidence in patients who are unfit for interventional procedures.
