High-rate continuous n -butanol production by Clostridium acetobutylicum from glucose and butyric acid in a single-pass fibrous bed bioreactor
Authors: Chang Wei-Lun , Hou Wenjie , Xu Mengmeng , Yang Shang-Tian
Published: July 2022

Biobutanol produced in acetone-butanol-ethanol fermentation at batch
mode cannot compete with chemically derived butanol because of the low
reactor productivity. Continuous fermentation can dramatically enhance
productivity and lower capital and operating costs but are rarely used
in industrial fermentation because of increased risks in culture
degeneration, cell washout, and contamination. In this study, cells of
the asporogenous Clostridium acetobutylicum ATCC55025 were
immobilized in a single-pass fibrous-bed bioreactor (FBB) for continuous
production of butanol from glucose and butyrate at various dilution
rates. Butyric acid in the feed medium helped maintaining cells in the
solventogenic phase for stable continuous butanol production. At the
dilution rate of 1.88 h , butanol was produced at
9.55 g/L with a yield of 0.24 g/g and productivity of 16.8 g/L∙h, which
was the highest ever achieved for biobutanol fermentation and an 80-fold
improvement over the conventional ABE fermentation. The extremely high
productivity was attributed to the high density of viable cells
(~100 g/L at >70% viability) immobilized
in the fibrous matrix, which also enabled the cells to better tolerate
butanol and butyric acid. The FBB was stable for continuous operation
for an extended period of over one month.
Drivers of population divergence and genetic variation in Elymus breviaristatus (Keng) Keng f. (Poaceae: Triticeae), an endemic perennial herb of the Qinghai-Tibet Plateau

Published: July 2022

Elymus breviaristatus (family Triticeae), a rare grass species with
excellent resistance and ecological importance, is narrowly distributed
on the Qinghai-Tibet Plateau (QTP). Populations of E. breviaristatus are
declining due to habitat fragmentation, and thus far, characteristics of
genetic differentiation and adaptive responses to climate change remain
poorly understood in this species. Here, we explored the genetic
structure of 18 natural populations (269 individuals) in the transition
zone between Tibet and the Hengduan Mountains using 15 expressed
sequence tag (EST)-SSR primer pairs and identified possible barriers to
gene flow that might have caused genetic discontinuities. Additional
analyses were performed to identify the environmental factors affecting
genetic diversity and to test whether the patterns of genetic variation
among populations were more consistent with the isolation by distance
(IBD) or isolation by environment (IBE) model. Multiple measures of
genetic diversity revealed that intra-population genetic variation was
low, while inter-population genetic variation was high. Clustering,
structure, and principal coordinate analyses identified three genetic
groups: (a) Eastern Qamdo, (b) Nagqu and Western Qamdo, and (c) Lhasa
and Nyingchi. A clear physical barrier to gene flow was formed by the
Yarlung Zangbo Grand Canyon and the Tanggula Mountains. We found that
both IBD and IBE contributed to the observed patterns of genetic
variation, indicating that the process of population differentiation was
affected by complex mechanisms. In addition, four precipitation-related
variables significantly affected population genetic variation,
especially in extremely cold and dry habitats. Overall, our results
emphasized the genetic fragility of E. breviaristatus populations and
showed that this species requires attention, as future climate changes
and human activities may further threaten its survival. In addition, the
genetic differences among E. breviaristatus populations should be
considered when formulating conservation measures for E. breviaristatus
populations in the study area.
Viral infections and drug hypersensitivity
Authors: Brüggen Marie-Charlotte , Pichler Werner
Published: July 2022

Virus infections and T cell-mediated drug hypersensitivity reactions
(DHR) can influence each other. In most instances, systemic virus
infections appear first. They may prime the reactivity to drugs in
two ways: First, by virus-induced second signals: certain
drugs like β-lactam antibiotics are haptens and covalently bind to
various soluble and tissue proteins, thereby forming novel antigens.
Under homeostatic conditions, these neo-antigens do not induce an immune
reaction, probably because co-stimulation is missing. During a virus
infection, the hapten-modified peptides are presented in an
immune-stimulatory environment with co-stimulation. A drug-specific
immune reaction may develop and manifest as exanthema. Second, by
increased pharmacological interactions with immune receptors (p-i) :
drugs tend to bind to proteins and may even bind to immune receptors. In
the absence of viral infections, this low affine binding may be
insufficient to elicit T cell activation. During a viral infection
immune receptors are more abundantly expressed and allow more
interactions to occur. This increases the overall avidity of p-i
reactions and may even be sufficient for T cell activation and symptoms.
There is a situation, where the virus-DHR sequence of events is
inversed: in drug reaction with eosinophilia and systemic symptoms
(DRESS), a severe DHR can precede reactivation and viremia of various
herpes viruses. One could explain this phenomenon by the massive p-i
mediated immune stimulation during acute DRESS, which coincidentally
acvitates many herpes virus-specific T cells. Through p-i stimulation,
they develop a cytotoxic activity with killing of herpes
peptide-expressing cells and release of herpes viruses. These concepts
could explain the often transient nature of DHR occurring during viral
infections and the often asymptomatic herpes-virus viraemia after DRESS.
Economic pressures of Covid-19 lockdowns result in increased timber extraction within a critically endangered region: a case study from the Pacific Forest of Ecuador
Authors: Tleimat Jacquelyn , Fritts Sarah , Brunner Rebecca , Lynch Ryan , Rodriguez David , McCracken Shawn
Published: July 2022

Although the COVID-19 lockdowns in 2020 had some environmental benefits,
the pandemic’s impact on the global economy has also had conservation
repercussions, especially in biodiverse nations. Ecuador, which is
heavily reliant on petroleum, agricultural exports, and ecotourism,
experienced a rise in poverty in response to pandemic shutdowns. In this
study, we sought to quantify levels of illegal timber extraction and
poaching before and after the start of COVID-19 lockdowns throughout two
protected areas (Reserva Jama Coaque [JCR] and Reserva Bosque Seco
Lalo Loor [BSLL]) in the endangered Pacific Forest of Ecuador. We
analyzed chainsaw and gunshot acoustic data recorded from devices
installed in the forest canopy from December 2019 to March 2020 and
October 2020 to March 2021. Results from generalized linear mixed
effects models indicated less chainsaw activity before lockdowns
(post.lockdown = 0.571 + 0.196 SE, p-value = 0.004), although increased
average rainfall also seemed to negatively affect chainsaw activity
(avg.rainfall = -0.005 + 0.001 SE, p-value < 0.001). Gunshots
were too infrequent to conduct statistical models; however, 87% of
gunshots were detected during the ‘lockdown’ period. Observational data
collected by rangers from these protected areas also noted an increase
in poaching activities beginning mid to late 2020 and persisting into
2021. These results add to the steadily growing literature indicating an
increase in environmental crime, particularly in biodiverse nations,
catalyzed by COVID-19-related economic hardships. Identifying areas
where environmental crime increased during pandemic lockdowns is vital
to address both socioeconomic drivers and enforcement deficiencies to
prevent further biodiversity loss and disease outbreaks and to promote
ecosystem resilience. Our study also demonstrates the utility of passive
acoustic monitoring to detect illegal resource extraction patterns,
which can inform strategies such as game theory modeling for ranger
patrol circuits and placement of real-time acoustic detection
technologies to monitor and mitigate environmental crimes.
Optimization of adeno-associated virus (AAV) gene delivery into human bone marrow stem cells (hBMSCs)
Authors: Yao Shaomian , Rong Weiqiong , Yuan Yuanying , Wen Xue
Published: July 2022

Efficiently delivering nucleic acid into mammalian cells is essential to
overexpress genes for assessing gene functions. Human bone marrow stem
cells (hBMSCs) are the most studied tissue-derived stem cells.
Adeno-associated viruses (AAVs) have been used to deliver DNA into
hBMSCs for various purposes. This study optimized the AAV transduction
protocol for high-efficiency DNA delivery into hBMSCs. hBMSCs were
infected with different serotypes of AAVs containing green fluorescence
(eGFP) reporter driven by the CMV promoter. GFP was monitored in the
infected cells. Cells were collected at designated time points after the
infection for RT-PCR to assess eGFP mRNA. The results indicated that the
order of transduction efficiency of the AAV serotypes was AAV2
> AAV2.7 > AAV6 > AAV6.2
> AAV1 > AAD-DJ. AAV2 could achieve almost
100% transduction at the MOI greater than 100K. Over 90% of cells
could be transduced at 20K to 50K MOI. About 80% transduction was seen
at MOIs of 10K and 15K. The eGFP expression reached the maximum about15-
25 days post-AAV2 infection. High levels of transcription were still
detectable at day 30 post-infection. We conclude that AAV2 and AAV2.7
can efficiently deliver transgene into hBMSCs for sustained expression
over one month.
FINANCIAL STABILITY OF RURAL MUNICIPALITIES IN POLAND’S LUBLIN VOIVODESHIP IN 2016-2020
Authors: Gałecka Agnieszka , Ganc Marzena
Published: July 2022

The stability of public services and the financial situation of local governments has a significant impact on a nation’s economic development. It also affects the long-standing process of political reforms aimed at promoting the efficiency of public sector units, their balanced budgets and financial stability. It is a concept defined in different ways, which is due, among other things, to its multifaceted nature and the lack of precisely defined measures to assess this phenomenon. The main objective of the paper was to assess the financial stability of rural municipalities in Poland’s Lublin voivodeship in 2016-2020. Within the framework of the main objective, ratio analysis and survey research was conducted. The paper was based on the study of literature on the subject, reports on the implementation of budgets in the studied municipalities published by the Regional Chamber of Accounts in Lublin, and a survey questionnaire. Based on the analyses, it was found that the studied municipalities in 2016-2020 recorded sustainability in terms of fiscal policy, and a stable level of financial liquidity and debt, albeit with a relatively low level of revenue independence. The crisis in 2020 caused by the Covid-19 pandemic caused a significant increase in the current expenditures of local government units compared to revenues, which were less than planned, although it did not significantly worsen the financial performance of the surveyed municipalities. In the opinion of the respondents (heads of rural municipalities), the vast majority of rural municipalities in the Lublin voivodeship were financially stable and the Covid-19 pandemic generally did not have a significant impact on their levels of stability.
A new approach to predict fouling using a transient CFD model and dynamic mesh
Authors: Flores-Balderas Juan , Alfaro-Ayala Jorge , Ramirez-Minguela Jose , Uribe-Ramírez Agustín , Lopez-Nunez Oscar
Published: July 2022

In this work, a novel approach to predict the fouling layer growth on the internal surface of a tube by means of a transient CFD model is presented. The transient CFD model takes into account the complexity of the chemical and physical phenomena coupled with dynamic mesh. The dynamic mesh method is programmed by the user defined functions for allowing to grow the fouling on the internal surface of the tube. The study is carried out through the CFD in a 2-D computational domain which contemplates: the radial effects of the profiles of temperature and velocity, and the consumption and productions of species due to chemical reactions. This approach is applied for the fouling deposits on the internal surface of a tube of a petrochemical fired heater, due to the thermal cracking process of oil. Results of the temperature, the oil velocity, the concentration of the distillate and the coke distribution fields are obtained. Moreover, the fouling layer growth, due to the deposit and accumulation along the time, is predicted, and also, the tube metal temperature is computed to identify the ?hot spots?. According to the results, the fouling layer reduces the diameter of the tube until 24% at the exit in comparison with the clean tube, which leads to the apparition of the ?hot spots? due to a high increment of the tube metal temperature at the exit.

Authors: He Lijuan , Sun Ningyu , Han Yuze , Yang Wenxuan , Huang Jiaohong
Published: July 2022

A combined magnetic refrigeration system that consists of external rotating magnetic field part of the rotary magnetic refrigerator and the flow path of the reciprocating magnetic refrigeration part was presented in this work. Experiments were carried out to investigate the influence of the structure for heat exchanger and active regenerator port on the refrigeration performance. With an operating frequency of 0.2 Hz and a magnetic field varying from 0 T to 1.3 T, a 22.2 K temperature span has been obtained when the heat exchanger with inner threaded coil tube was applied in the cold end. On the research of the hot end structure, the refrigeration temperature span of the plate heat exchanger is 22.7 K, the temperature of the cold end with fans is 6 K lower than that of the heat exchanger without fans. A 24.1 K temperature span of the combined magnetic refrigeration system can be obtained when the gradually varied port is used to the active magnetic regenerator.
Lossless storage and transportation law of 250m3 horizontal liquid hydrogen storage tank
Authors: Yao Shouguang , Yang Xiaoxu
Published: July 2022

In this paper, the effects of the initial filling rate and heat flux density on the natural convection inside the liquid hydrogen storage tank and the variation laws of temperature and pressure are studied. The study found that the optimal initial filling rate of the 250m3 liquid hydrogen storage tank was 86%. When the initial filling rate is in the range of 35% to 95%, the change of the heat flux density has a greater impact on the self-pressurization phenomenon than the change of the filling rate. When the initial filling rate is lower than 35%, the pressure in the tank rises sharply, and the change of the initial filling rate has a great influence on the self-pressurization phenomenon. The high initial filling rate and high heat flux density make the pressure rise of the liquid hydrogen storage tank faster during the pressure recovery period. When the liquid hydrogen begins to evaporate in large quantities, the low filling rate and high heat flux make the tank pressure increase faster. By comparing the three thermodynamic models with the simulation results, it is found that the pressure deviation of the 250 m3 liquid hydrogen storage tank with a filling rate of 86% is within 20% calculated by the three-zone model, which is the closest to the simulation results. The deviation of the surface evaporation model at high heat flux density and high filling rate reached 76% and 88.3%, respectively, which was the most affected calculation model by the change of heat flux density and initial filling rate.
Promoting of foam copper with chaotic distributed pores on the deflagration of premixed hydrogen-air flame in the tube
Authors: Long Fengying , Duan Yulong , Bu Yunbing , Jia Hailin , Yu Shuwei , Huang Jun
Published: July 2022

The deflagration flame of stoichiometric hydrogen-air mixtures is studied in this paper. Combined with the foam copper structure, the deflagration characteristic is analyzed in this paper. The experimental results show that the foam copper can improve the flow instability at the flame front and the degree of turbulence in the propagation process, the flame propagates more rapidly in turbulence state, and the number of stages of flame morphology during the propagation process in-creases. The classic ?tulip? flame can be transformed into a distorted ?tulip? flame and a fractal ?tulip? flame before it collapses. When the flame passes through the foam copper, the flame front velocity increases as the number of structural layers increases. The flame front velocity propagates at supersonic speed through the accumulation of three layers of foam copper. The instability of overpressure in the propagation process will cause oscillation. More layers of the structure, the oscillation frequency, and the amplitude of the overpressure are increased significantly. Foam copper structure has a reverse action on over-pressure. When the overpressure value is low in the early stage, the structure promotes the propagation, but the overpressure value is large in the later stage, the structure has a blocking effect.

Published: July 2022

The purpose of a gun bore evacuator on the turret-mounted gun barrel is to prevent the entry of the gaseous products of gun propellant combustion into the turret compartment of the vehicle after the breech block opening. The mathematical model which takes into account all of the main parameters influencing the pressure change inside the cylinder of the evacuator was developed. Differential equations that describe the flow field through the nozzle in the barrel wall and in the cylinder of the evacuator were solved numerically. Furthermore, the numerical simulations were performed using the ANSYS FLUENT in order to analyze the phenomena occuring in the evacuator during the charge and discharge cycles which are difficult to be taken into account with the analytical model. Aforementioned simulations were performed with the 3-D model of the evacuator and with the initial and boundary conditions obtained from the interior ballistic calculations. In order to find the change of the static pressure in the cylinder of the gun bore evacuator, the experimental research was performed. The comprehensive comparison between the numerical results and the experimental data has shown good agreement. Based upon this analysis, the influence of the evacuator?s main design parameters on the pressure distribution and the temperatures in the critical zones was determined. The influence of the propellant?s initial temperature on the pressure and wall temperatures in the evacuator was also analyzed, due to the wide range of gun operating temperatures and the possibility of erosion occurrence.

Authors: Boland Colleen M. , Daugherty Brian E. , Dickins Denise , Ewelt-Knauer Corinna
Published: July 2022

This paper describes a short-term, accounting-related study abroad program (STASA). Unlike traditional study abroad programs whose primary objective is to expose students to international environs and cultures, the described STASA also helps address the demands of accounting students’ future employers and accreditors by helping develop students’ transnational teaming skills and meaningfully integrating international accounting curricula. We do this by having U.S.-based students work both remotely and colocated with students from another country to complete an international accounting-related project. A detailed description of the STASA is provided that includes design considerations, learning objectives, implementation guidance, and possible grading options. Also included are answers to frequently asked questions about course execution, partnering with an international university, and funding.
Cash Theft Investigation and Evidence Documentation

Published: July 2022

In Case Task 1, students will act as forensic accounting services professionals (AICPA 2019, SSFS No. 1; IIA, AICPA, and ACFE 2008; NIJ 2007), using data analytics (AICPA 2017) to investigate possible thefts of cash. In Case Task 2, students will act as internal auditing services professionals (IIA 2017), using attribute estimation sampling to evaluate the effectiveness of internal controls in responding to the fraud risk regarding the alleged thefts of cash (IIA 2019a, Standards 2130.A1; COSO 2016). The case meets three primary Case Learning Objectives: (1) improve students' “click and play” learning experience about cash theft investigation and evidence documentation (AACSB 2018, Standard A5), (2) increase students' higher-order cognitive skills in deductive reasoning and inference about evidence (AICPA 2016, Exhibit 1), and (3) teach students to document workpapers professionally, clearly, and concisely. The implementation guide suggests ways to create multiple versions of the case and includes two case extensions.

Impaired insulin and incretin secretion underlie abnormal glucose tolerance (AGT) in pancreatic insufficient cystic fibrosis (PI-CF). Whether the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) can enhance pancreatic islet function in CF is not known. We studied 32 adults with PI-CF and AGT randomized to receive either GLP-1 (n=16) or GIP (n=16) during glucose-potentiated arginine (GPA) testing of islet function on two occasions with either incretin or placebo infused by randomized, double-blind, cross-over fashion. Another 4 adults with PI-CF and normal glucose tolerance (NGT) and 4 matched non-CF controls underwent similar assessment with GIP. In PI-CF with AGT, GLP-1 substantially augmented second-phase insulin secretion, but without effect on the acute insulin response to GPA or the proinsulin secretory ratio (PISR), while GIP infusion did not enhance second phase or GPA-induced insulin secretion but increased the PISR.  GIP also did not enhance second-phase insulin in PI-CF with NGT but did so markedly in non-CF controls. These data indicate that GLP-1, but not GIP, augments glucose-dependent insulin secretion in PI-CF, supporting the likelihood that GLP-1 agonists could have therapeutic benefit in this population.  Understanding loss of GIP’s insulinotropic action in PI-CF may lead to novel insights into diabetes pathogenesis.

"This study investigated the effect of ecological art (eco-art) projects on preservice classroom teachers’ attitudes towards and views on environmental issues. Ecological art is an art-oriented teaching model. The study adopted a mixed embedded research design and integrated ecological art into the “Environmental Education” course. The sample consisted of 78 first-year students from the department of classroom education of Ondokuz Mayıs University in the spring semester of the 2020-2021 academic year. Data were collected using student logs and a semi-structured interview questionnaire developed by the researchers, and the Environmental Problems Attitude Scale developed by Güven (2013). We developed a 14-week project and integrated visual arts education into the “Environmental Education” course. The project aimed to raise awareness through artistic expression. Each participant chose an ecological problem. The quantitative data were analysed using the Wilcoxon test. There was a significant difference between pre-test and post-test scores (p= 0.001). The qualitative data were analysed using content analysis. The results showed that the eco-art projects had cognitive, affective, and behavioural effects on participants. In other words, the eco-art projects raised their awareness of environmental issues. Participants stated that eco-art projects should be integrated into environmental education classes because they believed that art conveyed universal messages. We can conclude that eco-art projects bring an innovative and interdisciplinary perspective to environmental education and help preservice classroom teachers develop positive attitudes and views on environmental issues."
The role of avalanche education in assessing and judging avalanche risk factors
Authors: Landrø Markus , Engeset Rune , Pfuhl Gerit
Published: July 2022

Avalanche decision-making falls into two general categories; probabilistic approaches and analytical approaches. Analytical approaches have traditionally been considered applicable to experts only, as they require assessing risk factors precisely and understanding their relevance in each situation. In this study we question this assumption. We asked 1, 220 amateur backcountry recreationalists how relevant they rated and how precisely they could assess 11 avalanche risk factors. We investigated how their avalanche education and experience with avalanche incidents influenced their judgment of precision and relevance, and if avalanches become more predictable with more knowledge. Most recreationalists considered avalanches as predictable. These five factors were judged as highly relevant: signs of instability, distinguishing avalanche terrain from non-avalanche terrain, slope inclination, terrain traps, and distribution of weak layers. Relevance was independent of avalanche education and experience of incidents for all factors but danger level. Amateur recreationalists rated the relevance of the factors like that of experts. Rating of precision increased with more avalanche education, in particularly for these factors: distribution of the weak layers, terrain traps, avalanche size, recognizing avalanche terrain and stopping at safe spots. We recommend adopting an analytical approach for amateur backcountry recreationalists and discuss implications for avalanche forecasting and education.

Published: July 2022

The hydrodynamics of water-TiO2 nanofluid in the Ø32×3 mm horizontal Slinky collector of the heat pump, as well as the heat transfer from river water to the nanofluid have been studied in the paper. Water-TiO2 nanofluid provides attractive opportunities of the application in the energy industry due to its enhanced thermal properties. The thermal and hydrodynamic characteristics of the heat transfer fluid with spherical TiO2 nanoparticles in the temperature range from 2 to 12.5 °C have been analysed. The numerical studies have been performed within the range of change in the nanoparticles concentration from 0.3 to 1.3 vol. %. The influence of operating temperatures of water-TiO2 nanofluid on the efficiency of the energy system of a self-sufficient house, in particular, during the heating and non-heating seasons of the heating system operation for Kyiv region has been studied. The paper provides recommendations and confirms that the limitation of the practical use of water-TiO2 nanofluid is the increase in the viscosity of the heat transfer fluid, accompanied by the increase in power for its transportation. The calculated dependencies of the performance efficiency coefficient of water-TiO2 nanofluid application in the energy system on the content of nanoparticles in the heat transfer fluid have been obtained.

Sprouts as a natural food have been commonly consumed in different cultures, which are richer in health-promoting compounds than their mature counterparts. The purpose of this study was to investigate the effects of blue light on physiological and biochemical changes including sprout length, respiratory rate, free amino acids, ascorbic acid, glucosinolates, isothiocyanates and myrosinase activity in germinating cabbage sprouts. Furthermore, their correlation analysis was conducted to elucidate their changing patterns during germination and relationships with each other. The respiratory rate, free amino acids and ascorbic acid content were greatly enhanced by blue light compared to the darkness. Blue light could better retain glucosinolate content in cabbage sprouts than the darkness. More isothiocyanates formation was observed from cabbage sprouts under blue light, which was a result of the promoted myrosinase activity and higher glucosinolate content. These results indicate that blue light has selectively improved the nutritional compounds in germinated cabbage sprouts.

In the current Covid-19 transition period, innovations in early childhood learning models are needed that are effectively used. The many models of early childhood learning during this pandemic need to be studied further which are appropriate for implementation. This study aims to empirically verify the early childhood learning model during the COVID-19 pandemic and analyze the factors that influence early childhood learning during the Covid-19 period. The method used in writing this article is a systematic literature review, which is a literature search from national article sources conducted using indexed searches on Google Scholar and Microsoft Academic. This literature review was conducted using the prism method technique. The articles reviewed are the most recent 50 articles from 2020 to 2021, and the results were sorted into 26 articles. All articles are classified by year of publication, type of indexing journal, method, and early childhood learning model. The results of the study are presented as follows. (1) The search results prove an increase in the number of articles published from 2020-2021. (2) The results of the study show that the most widely used learning model in early childhood learning involves the participation and assistance of parents in children's learning at home through learning media created by teachers and distributed through social media. (3) The obstacles that can be identified are: (a) the role of parents in children's learning during the pandemic is still less than optimal, (b) the lack of mastery of technology skills of students and parents during online learning. So it is necessary to develop an early childhood learning model that can be applied in online implementation, able to facilitate collaboration between parents, teachers, and students.
