Published: July 2021

River management using the eco-hydraulic approach is aimed at preserving the ecological components in the river environment through hydraulic engineering. This study aims to identify the existing conditions on Kuin River border, analyze the relationship and influence of community activities on the banks of Kuin River on the water quality of Kuin River, and study the river development pattern with the concept of eco-hydraulic on Kuin River. Data were collected based on the results of field surveys and laboratory tests for water and soil. The results showed that the current condition of the riverbank of Kuin River has not fulfilled its function as a buffer space between the river and the mainland, due to the large number of community settlements rather than vegetation that functions to protect the river. Kuin River is polluted because several ecological indicators such as pH, Fe, BOD, and COD have exceeded the maximum allowable limits. This occurs due to social activities and development along the river, which have an impact on biotic and abiotic aspects of the river. The type of soil on the banks of the Kuin River is silt mixed with clay with moderate to high plasticity. Based on this condition, there is an assumption that the cliffs on the banks of Kuin River have the potential for landslides. Therefore, a pattern for developing cliff protection using riverbank vegetation components is recommended

Authors: Dzihora Yuliia , Stolyarenko Hennadiy
Published: July 2021

With the beginning of Anthropocene epoch, nature is facing a lot of environmental problems that drastically increased in the last century. On the current rate of resource consumption, soon nature will lose the ability for self-restoration. In order to avoid inevitable consequences of resources exploitation, new approaches should be developed in all areas of human life. Linear economy concepts that were utilized for a long time and were based on use and disposal of each separate resource depending on the purpose is not sufficient anymore. More holistic approach should be applied to overcome the challenges that we are facing now. Application of circular economy concepts for wastewater treatment facilities has a great potential to enhance sustainability of water management. This paper will focus on circular economy concepts applied for modern pilot installation that combines biological treatment and membrane separation and discusses the potential for the full-scale implementation. Since, pilot plant was operated without any chemicals addition it eases the use of the waste sludge that is received as a by-product for different purposes as agricultural application and biogas production.

The relevance of research is to ensure and improve the reliability of turbine generators (TG) with a hydrogen-water cooling system by monitoring the content of dissolved gases in the water of a hydrogen-water cooling system with monoethanolamine (MEA) – C2H7NO and water vapor in the cooling hydrogen of the turbine. In this work, the influence of ultrasonic vibrations on the decomposition of a mixture of water and turbine oil, organic acids (acetic acid - С2Н4О2, formic acid - СН2О2, oxalic acid - С2Н2О4) or monoethanolamine was determined. The distribution coefficients values were definedd for the following dissolved gases Н2, О2, N2, СО, СН4, С2Н2, С2Н4, С2Н6, С3Н6, С3Н8, which are of degradation products of water mix components when exposed to ultrasonic oscillation in the following system: «dissolved gas – mixture «water + monoethanolamine» – extractant argon (Ar)». The obtained values of the Кі distribution coefficients for dissolved gases in systems «dissolved gas – mixture «water + С2Н7NО» – extractant argon (Ar)» at a temperature of 293 K and a concentration of С2Н7NО at the level of 1 g/dm3 are close to similar values for dissolved gases in deionized water. The principle flow chart of multichannel gas chromatograph for detecting dissolved gases in water and steam of water in hydrogen was developed. Developed flow chart of 4-chennel gas chromatographer for defining dissolved gases in water includes the one gas chromatographer with conductivity detector, methanator, flame ionization detector, argon gas-bearing and supplementary gases of hydrogen and air.

Published: July 2021

Industrial and natural wastewater is one of the factors of environmental pollution, in particular, its water basin. Among others, fuel and oil pollutants are toxic substances that cause significant harm to all living things. It is necessary to create technologies using effective methods of wastewater treatment to solve such problems. It is possible to properly select and effectively use methods of treatment taking into account the nature, condition and concentration of contaminants in wastewater. These are the issues addressed in this article. Particular attention is paid to the use of flotation as a method of purification of stable highly dispersed emulsified wastewater containing oil or fuel contaminants in the technology of this type wastewater treatment. The main objectives of the study were to evaluate the impact of parameters and flotation reagents on the efficiency of the process of purification of stable highly dispersed emulsified wastewater. Flotation of these wastewaters was carried out on a laboratory flotation installation of pneumatic type and compared with the process of wastewater settling over time. Studies have shown that for stable emulsified wastewater containing oil or fuel contaminants with a low content of highly dispersed particles of inorganic nature or a stabilizer is present in them, it is advisable to use the flotation method with flotation units of pneumatic type. Analysing the results, it should be noted that the flotation method significantly reduces the purification time of highly dispersed emulsified wastewater from 3-5 hours of their settling in settling tanks-oil traps up to 10-20 minutes by the method of pneumatic flotation, while the degree of wastewater treatment increases in at least 1.5 - 2 times depending on the presence of fuel or oil contaminants in wastewater. If the wastewater contains a stabilizer, such as a surfactant, it can be used as an effective flotation reagent in the purification of this type of wastewater by flotation, which is not suitable for the settling process.
An American Business School’s Academic Advising and Professional Development Centers’ Early Pandemic Response
Authors: Blau Gary , Goldberg Daniel
Published: July 2021

As colleges and universities around the world grapple with the continuing impact of the ongoing COVID-19 pandemic, it is necessary for research to not only focus on student academic learning issues, but also test for maintained support of needed student resources such as Academic Advising and Professional Development Centers. Using the Senior Student Satisfaction Survey, two separate samples of graduating business undergraduates at a Mid-Atlantic University in the United States of America were surveyed, in late Spring 2019 (pre-pandemic) and late Spring 2020 (early pandemic). The goals of this study were two-fold. The first was to test for changes from pre-pandemic to early pandemic in seven student-related perception measures: attendance motivation, coursework challenge, professional development engagement, academic advising ease/quality, professional development ease/quality, business degree satisfaction, and perceived market value to potential employers. The second goal was to test for changes in the perceived relationships of five “independent variables”, i.e., attendance motivation, coursework challenge, professional development engagement, academic advising center ease/quality, and professional development center ease/quality, to two “dependent variables”, i.e., business degree satisfaction and perceived market value to potential employers. Comparing pre-pandemic (2019) to early pandemic (2020) perceptual change data, this study found that both the Academic Advising and Professional Development Centers handled these student-based perception variables from the surveys quite well. When the campus was suddenly closed due to the pandemic, both Centers successfully made quick adaptive changes to virtual models to handle initial student needs.
Microbiome First Medicine in Health and Safety
Authors: Dietert Rodney R.
Published: July 2021

Microbiome First Medicine is a suggested 21st century healthcare paradigm that prioritizes the entire human, the human superorganism, beginning with the microbiome. To date, much of medicine has protected and treated patients as if they were a single species. This has resulted in unintended damage to the microbiome and an epidemic of chronic disorders [e.g., noncommunicable diseases and conditions (NCDs)]. Along with NCDs came loss of colonization re-sistance, increased susceptibility to infectious diseases, and increasing multimorbidity and polypharmacy over the life course. To move toward sustainable healthcare, the human micro-biome needs to be front and center. This paper presents microbiome-human physiology from the view of systems biology regulation. It also details the ongoing NCD epidemic including the role of existing drugs and other factors that damage the human microbiome. Examples are provided for two entryway NCDs, asthma and obesity, regarding their extensive network of comorbid NCDs. Finally, the challenges of ensuring safety for the microbiome are detailed. Under Microbiome First Medicine and considering the importance of keystone bacteria and critical windows of development, changes in even a few microbiota-prioritized medical decisions could make a significant difference in health across the life course.

Currently, various industrial processes are carried out in fluidized bed reactors, such as fermentation, water treatment, and algae growth. Knowing its internal dynamics is fundamental for the intensification of these processes. This work assesses the motion of fluidized calcium alginate spheres under the influence of an upward fluid flow within a 1.2 m high and 0.1 m inner diameter acrylic column. The Radioactive Particle Tracking technique is a proper methodology to study the internal dynamics of these kinds of equipment. Liquid-Solid Fluidized Bed is compared with the Gas-Liquid-Solid Fluidized Bed operation mode in terms of mixing behavior. Data gathered is analyzed in view of Shannon entropy as a dynamic mixing measure. Mixing times are found to be of the same order of magnitude. However, the Liquid-Solid Fluidized Bed achieves a lower homogenization degree. Also, we found good agreement between two criteria for assessing stability for the mixed state: the Shannon Entropy time-series plateau and the Glansdorff-Prigogine criterion based on Fisher information.

We report diagnosis of Neuronal Ceroid Lipofuscinosis Type 2 (CLN2), a rare, hereditary neurodegenerative disease of childhood, in a four and a half year old girl, the first child of non-consanguineous parents with no family history. Despite extensive efforts by the parents, her clinical condition remained undiagnosed and without management, until recently. Our published “Bottom-up Approach”, based on comprehensive and multidisciplinary clinical, pathological, radiographical and genetic evaluations, played key role in diagnosis of the disease. Detailed analyses involving Next Generation Sequencing confirmed a missense variation NC_00011.10:g.6616374C>T (NP_000382.3:p.Arg339Gln; rs765380155) in exon 8 of TPP1 gene. In silico analyses predicted it to be highly pathogenic. Further family screening (including her both unaffected parents and asymptomatic, one year old younger sister) of the identified variation through Sanger Sequencing, revealed a perfect autosomal recessive segregation in the family. This study is the first case report on classic CLN2 from Jammu and Kashmir-India. This study is also indicating the effectiveness of our “Bottom-up Approach” in understanding rare disorders in low resource regions and the importance of timely diagnosis. Like in the proband, had diagnosis been established a bit early, the family might have benefitted at least with reference to their second child through counselling programmes.

The objective of this study aimed to develop biodegradable calcium alginate microspheres carrying doxorubicin (Dox) at the micrometer-scale for sustained-release and the capacity of pH regulatory for transarterial chemoembolization. Ultrasonic atomization and CaCl2 cross-linking technologies were used to prepare the microspheres. A 4 by 5 experiment was first designed to identify imperative parameters. The concentration of CaCl2 and the flow rate of the pump were found to be critical to generate microspheres with a constant volume median diameter (~ 39 m) across 5 groups with different alginate:NaHCO3 ratios using each corresponding flow rate. In each group, the encapsulation efficiency was positively correlated to the Dox-loaded efficiency. Fourier-transform infrared spectroscopy showed that NaHCO3 and Dox were step-by-step incorporated into the calcium alginate microspheres successfully. Microspheres containing alginate:NaHCO3 = 1 exhibited rough and porous surfaces, high Young’s modulus and hardness. In each group with the same alginate:NaHCO3 ratio, the swelling rates of microspheres were higher in PBS containing 10% FBS compared to those in PBS alone. Microspheres with relative high NaHCO3 concentrations in PBS containing 10% FBS maintained better physiological pH and higher accumulated Dox release ratios. In two distinct hepatocellular carcinoma-derived cell lines, treatments with microspheres carrying Dox demonstrated that the cell viabilities decreased in groups with relative high NaHCO3 ratios in time- and dose-dependent manners. Our results suggested that biodegradable alginate microspheres containing relative high NaHCO3 concentrations improved the cytotoxicity effects in vitro.

Abstract. Since the passage of Public Law 95-87, the Surface Mining Control and Reclamation Act (SMCRA) in 1977, reclamation success of prime farmland after coal mining has been determined by long-term crop yield testing. States such as Illinois and Indiana require that reclamation success be based on crop production of mined land. This process often can continue for many years, especially for lands failing to meet production standards in a specified time period. Needs have been expressed by landowners, mine operators, and regulators for methods to expediate this process. A soil property based model could relieve this burden and ensure the most efficient process for returning the soil resource to the landowner. The objective of our work was to develop a soil-based model to replace the current crop yield-based system and to evaluate mined- land for diagnostic purposes. Georeferenced corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yield, cone penetrometer test (CPT), VIS-NIR spectrophotometer, apparent electrical conductivity (ECa), elevation and terrain derivatives, fertility, and other site characteristic data were collected on fields at the Lewis Mine site in southwestern IN, the Cedar Creek Mine site in western IL, and the Wildcat Hills Mine site in southern IL. Soil-based productivity models were developed using regression and multivariate techniques to assign probabilities of meeting crop yield standards at the partial-field level. Our research indicates that soil compaction and water availability primarily influence a field’s ability to meet crop yield standards across time. Model validation between fields and among sites has been encouraging, thus we propose modeling soil variability as a diagnostic tool to identify problematic field areas and to complement yield-based requirements.

Pediatric ACL Revision Using Salvaged Iliotibial Band Autograft in a Physeal-Sparing Multiligamentous Knee Reconstruction
Authors: Hayashi Brooke , Spector Chelsea , Lee R. Jay
Published: July 2021

Case:

Iliotibial band (ITB) autograft is used for anterior cruciate ligament (ACL) reconstruction in prepubescent patients. No reports have described ITB salvage techniques for failed reconstruction. We describe a 13-year-old boy who sustained a multiligamentous knee injury, experienced a failed primary reconstruction, and required a revision ITB ACL, lateral collateral ligament, and posterior lateral corner reconstruction with reuse of his ITB autograft. At the 2-year follow-up, he returned to playing competitive sports.

Conclusion:

This case shows that salvage of an ITB ACL autograft can be an option in early reconstruction failure.

Published: July 2021

Case:

An 18-year-old adolescent boy presented with knee pain and stiffness secondary to tibial plateau valgus malunion and osteochondral defect, 8 months after initial injury/fixation. We opted for a novel technique that reconstructs the convex lateral tibial plateau by using osteotomy and an osteochondral autograft harvested from the lateral aspect of the ipsilateral femoral condyle.

Conclusion:

The reported novel reconstruction technique is inexpensive, achievable with routine techniques, and demonstrated a favorable short-term outcome. At 3 years of follow-up, the patient had excellent, asymptomatic, left knee mobility and function with radiographic evidence of mild posttraumatic arthritis despite normal knee alignment.
Sedimentology and stratigraphic architecture of a fluvial to shallow-marine succession: The Jurassic Dhruma Formation, Saudi Arabia

The interaction of fluvial, tidal, and wave processes in coastal and paralic environments gives rise to sedimentary successions with highly varied styles of facies architecture; these are determined by the morphology and evolutionary behavior of the range of coastal sub-environments, which may be difficult to diagnose in subsurface sedimentary successions with limited well control.

This study presents depositional models to account for stratigraphic complexity in a subsurface fluvial to shallow-marine succession, the Middle Jurassic Dhruma Formation, Saudi Arabia. The study achieves the following: i) it examines and demonstrates sedimentary relationships between various fluvial, nearshore, and shallow-marine deposits, ii) it develops depositional models to account for the stratigraphic complexity inherent in fluvial to shallow-marine successions, and iii) it documents the sedimentology and the stratigraphic evolutionary patterns of the lower Dhruma Formation in the studied area of Saudi Arabia. The dataset comprises facies descriptions of 570 m of core from 14 wells, 77 representative core thin sections, 14 gamma-ray logs, and FMI image logs from 4 wells. These data are integrated with quantitative information from > 50 analogous systems from a wide range of modern and ancient settings, stored in a relational database. Stratigraphic correlations reveal the internal anatomy of the succession.

Facies associations are representative of fluvial channels, intertidal flats, pedogenically modified supratidal flats or floodplains, river-influenced tidal bars, weakly storm-affected shoreface and offshore-transition zones, storm-dominated delta-front and prodelta settings, and an open-marine carbonate-dominated shelf. These sub-environments interacted in a complex way through space and time. The vertical succession of the studied interval records an overall transition from coastal-plain deposits at the base to marine deposits at the top. As such, the succession records a long-term transgressive, deepening-upward trend. However, this general trend is punctuated by repeated progradational events whereby coastal sand bodies of fluvial, wave, and tidal origin prograded basinward during stillstands to fill bays along a coastline. The nature of juxtaposition of neighboring sub-environments has resulted in a sedimentary record that is highly complex compared to that generated by morphologically simple shoreface systems that accumulate more regularly ordered stratal packages.

The potential health risk of heavy metals (HMs) in campus dust may threaten the health of thousands of students, teachers, and their families in Wuhan, the university cluster in Central China every day. In this research, the pollution characteristics and health risk with HMs was the first time presented in campus dust from the canteen, playground, dormitory, and school gate to date. The average HMs concentration in campus dusts ranked Pb (83.5 mg kg-1) > Cu (70.2 mg kg-1) > Zn (47.2 mg kg-1) > Cr (46.0 mg kg-1) > Ni (22.7 mg kg-1) > As (15.2 mg kg-1) > Cd (3.38 mg kg-1). The HMs would more likely to accumulate in dormitory dust and canteen dust. In the downtown area, Zn, As, and Cd had been preliminarily identified from fossil fuel combustion and natural geochemical processes. Cu and Pb would source from cooking and traffic transportation. Ni and Cr would likely reflect the contributions of natural soil weathering. Although, no significant non-carcinogenic health risks were found to students or teachers from campus dust. Their children would more likely to exposure health risks when eating in the canteen, playing on the playground, or walking around the school gate. While the incremental lifetime cancer risk values revealed respiratory intake of HMs does not pose a carcinogenic risk on the campus.

Background

The Andes are recognized as center of biocultural and biological diversity that provide multiple ecosystem services threatened by different anthropogenic forces. Here, fires are widely used in agriculture and other traditional activities with the potential to become larger-scale, unmanageable “wildfires” and contribute to the degradation of both ecosystems and human livelihoods. In this study, we assess the temporal and spatial pattern of MODIS and VIIRS Active Fire Data (AFD) and their relationships to 9 environmental conditions and human activities across the three zones of the Huascaran Biosphere Reserve (HBR), Ancash, Peru between 2001 and 2020.
Results

Xeric climatic conditions seem to drive the temporal AFD pattern across and within years in the HBR. Across years, an oscillating increment of active fire alerts was evident, with years 2016 and especially 2020 displaying the highest AFD records of the two decades. Both correspond to years with the lowest mean annual precipitation. Seasonally, AFD also peaked at the end of the dry season (August and September), but AFD continue until late November of 2016 and 2020. The amount of people on the other hand, measured in terms of population and number of rural villages, is the main driver of where AFA occur, increasing along the limits of the Huascaran National Park (HNP) and the Buffer Zone (BZ) and in weakly controlled areas within the park.
Conclusions

We conclude that a combination of both, xeric conditions, and human pressures, seems to interact and produce high numbers of AFD along key Andean ecosystems like Puna grasslands and shrublands that are not ecologically adapted to this type of pressures. Land transformation and a limited capacity of control over key areas within the HNP seem to play an important role in where and when wildfires occur. Finally, although 2020 was an arid year, the covid-19 pandemic would have exacerbated the number of AFDs that occurred in the area, demonstrating that the effects of the pandemic go beyond health problems.
