Production of esterified nanofibrillated cellulose from a lesser-known wood Species (Macaranga hypoleuca)
Authors: Sutrisno Eko , Tanpichai Supachok , Chuangchote Surawut
Published: February 2022

Macaranga hypoleuca, a lesser-known and rarely used wood species, is a pioneer species in the secondary succession that is classified as a fast-growing plant with long fibers. M. hypoleuca was composed of holocellulose, lignin, and extractives, at contents of 68.1 ± 0.5%, 25.5 ± 0.6%, and 4.7 ± 0.1%, respectively. In this study, refined M. hypoleuca pulp was treated by alkali treatment, delignification, and maleic acid hydrolysis. The pre-treated pulp was further disintegrated by mechanical treatment, which produced nanofibrillated cellulose (NFC) with a yield of 53.5 ± 2.7%. The average diameter of the NFC was 43.0 ± 4.9 nm. The use of maleic acid (C4H4O4) hydrolysis also reduced the hydrophilicity of the NFC, as confirmed by the Fourier-transform infrared (FTIR) spectra. It was determined that the Macaranga tree is a suitable lignocellulose source to produce NFC, which can be used in transparent flexible substrates, coating, and composite applications.
Analyzing changes in the U.S. wood furniture industry from 1997 to 2019: Production, net imports, and consumption
Authors: Luppold William G. , Bumgardner Matthew S.
Published: February 2022

Wood-consuming furniture manufacturers (WCFM) are major users of forest products in the United States. Between 2000 and 2009, the real value of domestic WCFM shipments (production) declined by 51%. After 2009, WCFM shipments fluctuated, but by 2019 shipments were 48% below 2000 levels. A major contributor to this decline was furniture imports. In 1997, imports accounted for 6% and 23% of the value of upholstered household furniture (UHF) and wood household furniture (WHF), available to U.S. consumers, respectively. In 2019, imports accounted for 35% and 78% of domestically available UHF and WHF, respectively. The primary source of imported UHF in 2019 was China, while Vietnam was the most important source of WHF. Domestic consumption also influences WCFM shipments. Between 1997 and 2019, consumption of UHF by U.S. end-users increased; since 2002, this increase was primarily supplied through increased imports. Since 2005, domestic consumption of WHF declined by 45%, which contributed to the 75% decline in domestic shipments since that year. Wood office furniture and related products also have experienced a 40% decline in consumption since 2000, which coincided with a 41% decline in shipments. More research is needed to determine the impact of decreased WCFM shipments on U.S. forest product production and prices.
Non-dominated sorted genetic algorithm-II algorithm-based multi-objective layout optimization of solid wood panels
Authors: Wang Baogang , Yang Chunmei , Ding Yucheng
Published: February 2022

Common solid wood panel defects affect the appearance of timber products and reduce their value for use. It is necessary to remove defects from solid wood panels to achieve a panel layout. A whole wooden beam column is cut into solid wood panels of different sizes, according to the requirements. Aiming to overcome problems of weak convergence ability, single-objective optimization, and the poor optimization effect of solid wood panel layout optimization based on a traditional genetic algorithm, an improved multi-objective solid wood panel layout optimization based on NSGA-II (Non-dominated sorted genetic algorithm-II) algorithm was proposed. Reverse learning was used to generate a reverse population to increase the search capability of the algorithm and to solve the problem of insufficient population diversity in the genetic algorithms. A combination of directional variation and uniform variation was used to improve the optimization effect and solve the problem of small individual differences in the evolution of the algorithm. The improved multi-objective optimization algorithm showed better optimization and stability than the NSGA-II algorithm. The number of convergence iterations was reduced and simultaneous optimization of multiple objectives can be realized.

Authors: Wang Jian-Hui , Mahmoud Mohamed S. , Mahmoud Ahmed S.
Published: February 2022

Water treatment using nano-materials can have a significant impact due to its surface properties. Coagulation techniques were studied by using 3 mL/L of 0.5% of different coagulants (polyacrylamide, poly aluminum chloride (PAC), ferric chloride, aluminum sulfate, and nanocellulose). Results indicated that the turbidity removal efficiency were 91.6%, 93.04%, 95.2%, 95.4%, and 99.4%, respectively. Treatment of water samples collected from the Ismailia Canal, the Damietta branch of the Nile Delta, and a wastewater treatment plant located in Cairo (Egypt) using nanocellulose fibers was studied. For the Ismailia Canal sample, the removal of turbidity, chemical oxygen demand (COD), biological oxygen demand (BOD), and phosphorous were 96%, 83.3%, 100%, and 100%, respectively. For the Damietta branch sample, the removal of turbidity, COD, BOD, and phosphorous were 87.5%, 81.3%, 88.9%, and 99.1%, respectively. For the wastewater treatment plant sample, the removal of turbidity, COD, BOD, and phosphorous were 86.4%, 91.96%, 92.86%, and 91.74%, respectively. Nanocellulose-nano zero-valent iron composite (NC-nZVI) was investigated for phosphorous removal at different operating conditions. Results showed phosphorous removal efficiencies of 91 and 100% for initial phosphate concentrations of 10 and 1 mg PO43– P/L, respectively. Different isothermal analyses were performed for monolayer and multilayer adsorption processes.
Exergetic comparison of electrical heating gasification and water electrolysis assisted gasification for renewable electricity storage
Authors: Song Guohui , Qiao Haiqing , Gu Haiming , Cui Xiaobo
Published: February 2022

To develop an efficient solution for the storage of renewable electricity and utilization of biomass or waste within the power-to-X concept, the electrical heating gasification (EHG) technology for industrial-scale application was proposed and compared with water electrolysis-assisted gasification (WEG). The two technologies were compared in terms of composition, yield, and exergy efficiency. The results indicate that EHG consumes less electricity and generates syngas with higher chemical exergy. The maximum exergy efficiency of EHG was calculated as 80.76%. Electrical heating gasification is more efficient than WEG based on either the current state or the potential progress in the future. Additionally, the exergy efficiency of water electrolysis ranges between 54.1% and 79.1%, which implies that more efforts are needed in the future to reduce the specific electricity consumption. This work is valuable to guide the development of an electrical heating gasifier and to improve performances of power-to-X technologies.
Kinetics of delignification and carbohydrate degradation during the ozone bleaching of low-consistency hardwood pulps
Authors: Guo Yixuan , Zhang Ye , Liu Mingyou , Chen Xia , Tian Xiaofei
Published: February 2022

With rising concern for environmental protection, the use of ozone has been increasingly studied in the pulp and paper industry. Feasible models for efficient quality prediction and process control are in high industrial demand. In this study, the reaction kinetics of delignification and viscosity during the ozone bleaching process (OBP) of low-consistency hardwood pulp (LCHP) are explored using exponential and zero-order response models, respectively. The effects of ozone dose, reaction temperature, reaction time, and pH on the changes in residual lignin content and pulp viscosity were analyzed. The corresponding kinetic parameters, such as the reaction order, rate constant (k), and activation energy (E), were also obtained. The models suggest that temperature should be one of the most significant factors affecting the effectiveness of the OBP system. The strategy to improve the OBP selectivity is based on reducing the reaction temperature while increasing the ozone concentration and pH in the reaction system.
Co-delivery of genes can be confounded by bicistronic vector design
Authors: Moradian Hanieh , Gossen Manfred , Lendlein Andreas
Published: February 2022

Maximizing the efficiency of nanocarrier-mediated co-delivery of genes for co-expression in the same cell is critical for many applications. Strategies to maximize co-delivery of nucleic acids (NA) focused largely on carrier systems, with little attention towards payload composition itself. Here, we investigated the effects of different payload designs: co-delivery of two individual “monocistronic” NAs versus a single bicistronic NA comprising two genes separated by a 2A self-cleavage site. Unexpectedly, co-delivery via the monocistronic design resulted in a higher percentage of co-expressing cells, while predictive co-expression via the bicistronic design remained elusive. Our results will aid the application-dependent selection of the optimal methodology for co-delivery of genes.

Published: February 2022

Gabapentin is frequently used as an analgesic in patients with chronic kidney disease (CKD). It is excreted exclusively through kidney, and therefore impairment in kidney function could lead to gabapentin accumulation and hence toxicity. We present our experience of 3 cases with Gabapentin toxicity who were managed according to the severity of symptoms. Case 1: A 32-year-old male was found lying unconscious after consuming around 12,000 mg of gabapentin and had respiratory depression, rhabdomyolysis, and acute kidney injury (AKI). Patient was man-aged with supportive care and hemodialysis (HD). Case 2: A 64-year-old male CKD Stage 5 (5D) patient with diabetic neuropathy was started on gabapentin 300 mg daily by his primary care physician 1 week back. Patient started to feel sleepy and developed altered sensorium and myoc-lonus. Discontinuation of gabapentin and a session of HD led to dramatic improvement in patient’s status. Case 3: A 70-year-old female diabetic patient with CKD Stage 3 and had diabetic neuropathy. Her neuropathic symptoms had improved with gabapentin 300 mg twice daily, but lately patient was feeling sleepy during the day and was confused. Discontinuation of the drug led to improvement in symptoms. Gabapentin is a rel-atively safe medication, but in certain clinical scenarios, particularly in impaired renal functions, can lead to severe complications. Moreover, it per se can rarely lead to rhabdomyolysis and AKI. Clinical suspicion and timely decontamination are needed, and sometimes dialytic therapy may be needed.

Published: February 2022

Crescentic glomerulonephritis (CrGN) is characterized by the presence of crescents in more than 50% of glomeruli. This study aims to identify the etiology and clinicopathological features and outcomes of CrGN. In this observational study, 80 biopsy-proven CrGN were included. Patients’ demographic profile, clinical parameters, treatments, and outcomes were collected and analyzed. The mean age in our study population was 40.86 ± 16.5 years. Type II CrGN was the most common type of CrGN. Female predominance was observed in type I and type II CrGN. The highest percentage of glomeruli with crescents was seen in type I (87 ± 15.2%, P = 0.04), followed by type III and type II. At the last follow-up, mean estimated glomerular filtration rate was 25.8 ± 11.41 mL/min/1.73 m2 and was significantly lower in type I CrGN (11.6 ± 4.8 mL/min/1.73 m2 P = 0.001). The overall 5-year renal survival rate was 55% and was highest in type II (69.4%), followed by type III and type I (27.3%) CrGN (P = 0.0299). In our study, oliguria at the time of presentation, percentage of crescents, glomerular sclerosis, and moderate/severe IFTA were associated with poor renal outcomes. In conclusion, CrGN was seen in 5.7% of kidney biopsies in our study. Type II CrGN was the most common type of CrGN followed by type III CrGN. Renal survival was poor in type I CrGN patients compared to type II and type III CrGN. Also, oliguria, crescents, glomerular sclerosis, and moderate/severe IFTA were associated with poor renal outcomes.

COVID-19 pneumonia and community-acquired pneumonia (CAP) have been associated with morbidity and mortality. The aim of this study was to evaluate the outcome of hospitalized patients with COVID-19 pneumonia versus CAP in terms of mortality. This was a retrospective cohort study conducted between pre-COVID-19 era (May 2019–November 2019) and COVID-19 era (May 2020–November 2020). The study included all adult patients with COVID-19 pneumonia (Group 1) and adult patients with CAP but are COVID-19 negative (Group 2). A total of 106 patients were included in the study, of which 56 were in the COVID-19 pneumonia group and 50 in the CAP group. Patients who developed acute kidney injury (AKI) were 60.7% (n = 34) in Group 1 and 48% (n = 24) in Group 2. Mortality occurred in 37.5% (n = 21) patients in Group 1 and 12.0% (n = 6) in Group 2 (P = 0.003). A total of 52 patients required admission to intensive care unit (ICU), of which 44.6% (n = 25) were in Group 1 and 54.0% (n = 27) in Group 2. Of the 58 patients who developed AKI, 3 (8.8%) patients in Group 1 passed away compared to none in Group 2. Moreover, 58.8% patients (n = 20) in Group 1 and 70.8% patients (n = 17) in Group 2 required ICU admission. Mortality rate in the ICU was 80.0% (n = 16) and 35.3% (n = 6) in Groups 1 and 2, respectively (P = 0.006). The overall mortality rate was higher in case of COVID-19 patients than those with CAP. In case of patients with AKI, mortality rate in the ICU was significantly higher in COVID-19 pneumonia patients compared to CAP patients.

There is minimal information on coronavirus disease 2019 (COVID-19) in developing countries regarding renal transplant recipients (RTRs). This paper aimed to study the clinical profile, immunosuppressive regimen, treatment, and outcomes in an RTR with COVID-19. This retrospec-tive study was conducted in the nephrology department of Sri Aurobindo Medical College & Postgraduate Institute, Indore (MP), India, from April 1, 2020 to December 15, 2020. We studied 15 patients, of which 13 were treated at our hospital and two were treated in OPD. The median age of transplant recipients was 45 (Interquartile range [IQR]: 26–62) years, the majority being males, and recipients presented at a median of 4 (IQR: 0.3–11) years after transplant. The most common comorbidities included hypertension in 14 (94%) and diabetes 3 (20%) patients. The presenting symptoms at presentation were cough (80%), headache (52%), fever (46%), and breathlessness (26%). Clinical severity as per comput-erized tomography (CT) severity score ranged from mild (20%), moderate (53%), and severe (27%). Strategies to modify immunosuppressants included discontinuation of antimetabolites without changes in calcineurin inhibitors and steroids (100%). Antiviral therapy (Favipiravir and Remdesivir) was associated with better outcomes and reduced hospital stay. Risk factors for mortality included ABO-incompatibility, severity of disease, high Coronavirus Disease 2019 (COVID-19) Reporting and Data System (CO-RADS) score, allograft dysfunction before COVID-19 infection, acute kidney injury, elevated inflammatory markers, and intensive care unit/ventilator requirement. Overall patient mortality was 13.2%. Risk factor for mortality in COVID-19 positive with RTR appears to be ABO-incompatible transplant, having a previous history of rejection, and patient requiring ventilatory support.

Authors: Martín Rocío Belén , Silvio Donolo Danilo , Magallanes Graciela Susana
Published: February 2022

El escrito que aquí se presenta tiene por objetivos, por un lado, explorar las habilidades socio-emocionales de los integrantes de una cooperativa en relación con el trabajo que realizan, analizando su influencia en la construcción de la identidad personal y colectiva; y por otro lado, atender a los procesos de aprendizaje, educación y participación en la conformación y consolidación de una comunidad de práctica.
Se estudió el caso de una cooperativa agrícola y tambera: “El Craikense”, dedicada a la producción láctea desde 1926, y situada en la provincia de Córdoba, Argentina. Para este estudio, se realizó una entrevista en profundidad al presidente de la cooperativa, se analizaron las observaciones registradas de la asamblea general ordinaria y los documentos de memoria y balance.
Entre los resultados hallados, se pudo comprender a la cooperativa como una comunidad de práctica atravesada por procesos de participación conjunta, co-construcción de identidades y habilidades socioemocionales con énfasis en lo interpersonal.
La cooperativa como comunidad fomentó el aprendizaje colectivo entre los miembros mediante el intercambio de experiencias; compartiendo y creando conocimiento y saberes para mejorar el impacto del proyecto cooperativo en la región.
Formas asociativas sin ánimo de lucro más convenientes para desarrollar agronegocios en el Departamento de Antioquia
Authors: Acevedo González Gabriel Antonio
Published: February 2022

Uno de los principales limitantes para la sostenibilidad de los pequeños y medianos productores agrarios, es el deficiente sistema de comercialización, caracterizado por actores con alto poder de negociación que operan como compradores y otros con muy poca capacidad de negociación que son los productores agrarios. Los campesinos, además de la necesidad de mejorar la comercialización, deben ser competitivos para poder responder a una demanda cada día más compleja, situación difícil que no podrán lograr en forma individual, luego se tendrán que asociar, conformando agronegocios asociativos sin ánimo de lucro (ASALs), con alto poder de negociación y solidez suficiente para ser sostenibles. Los productores han intentado muchas formas asociativas para comercializar sus productos, con algunos éxitos y muchos fracasos.
Review Essay: Deepening Deliberative Democracy – Experimentation vs. Naturalization
Authors: Wong James K.
Published: February 2022

Hélène Landemore and Ana Tanasoca have recently proposed two different approaches to deepening the deliberative dimension of democracy. In Open Democracy (2020), Landemore introduces a novel paradigm of democracy—open democracy—which grants ordinary citizens access to an actual exercise of political power through innovative forms of democratic representation. In Deliberation Naturalized (2020), Tanasoca develops a naturalized normative theory of deliberative democracy which stresses the role of citizen deliberation in what she refers to as ‘naturalistic’ settings, i.e., the public sphere. Both texts invite us to stretch our imaginations of how contemporary democracy can be deepened in deliberative ways.
What Happens When Banks Tighten C&I Loan Supply?

Published: February 2022

The supply of bank credit is an important driver of macroeconomic outcomes, with significant implications for employment and output (Basset et al., 2014; Chodorow-Reich, 2014). However, studying credit supply is not straightforward for several reasons.
Estimating U.S. Cross-Border Securities Flows: Ten Years of the TIC SLT
Authors: Bertaut Carol , Judson Ruth
Published: February 2022

The Treasury International Capital (TIC) system collects cross-border securities positions and transactions data and is the primary source of information on foreign official and private demand for U.S. Treasuries and other U.S. securities, as well as for U.S. investment in foreign securities. As noted in earlier work, though, the TIC system currently collects data separately on holdings of securities (the monthly TIC SLT and the annual SHL/SHC collections) and on transactions, the TIC S, and these two data streams can be difficult to reconcile, making interpretation of movements in the data challenging.
Activating dormant strongyloidiasis secondary to COVID-19 treatment
Authors: Fahad Alkaabba , Holman Li , Farrah Ibrahim
Published: February 2022

The SARS-CoV-2 pandemic has grown into a major global concern with huge efforts to combat the spread. Exaggerated inflammatory response plays a major role in which was the rationale to use corticosteroids to treat patients. However, multiple studies showed an association between opportunistic and bacterial infections with corticosteroid therapy. We report a case of a 76 year old patient diagnosed with COVID-19 treated with 10 days Dexamethasone and Remdesivir who presented with abdominal symptoms with eosinophilia. Biopsy and stool studies revealed Strongyloides stercoralis larvae. The patient was treated with 2 doses of Ivermectin with significant clinical resolution. Clinician should have high clinical suspicion for Strongloydiasis in patients who have lived or visited endemic areas and for patients with unexplained eosinophilia. Prompt treatment with Ivermectin is crucial for confirmed cases and high risk cases where obtaining a diagnosis is unfeasible.
Factors influencing value addition to cashew products processed in the South-East Zone, Nigeria: A multinomial logistic regression approach
Authors: Anayochukwu Victor EZE , Ibrahim Macharia , Lucy Ngare
Published: February 2022

Nigeria is a leading cashew producer, but this has not been reflected in the development of the downstream cashew value chain industry. The launch of the “Agriculture Promotion Policy (2016 – 2020)” document was designed to encourage value addition to export crops such as cashew as ways of creating jobs and wealth to value chain actors. However, it is still unclear why cashew processors are unable to exploit this opportunity to improve value addition to cashew. This makes it imperative that factors influencing value addition to cashew products in the South-East zone, Nigeria be analyzed. A cross-sectional survey design involving a structured questionnaire was used to obtain data from 353 randomly selected respondents from the South-East zone, Nigeria. The study found that income, access to market, product characteristics, and cost of cashew processing technology significantly influence value addition to cashew products in the two models, whereas government policy on cashew processing and market facilities were significant in the second model. The relative risk ratios for age, educational level, income, processing experience, access to market, distance to market, government policy on cashew processing and market facilities were > 1, suggesting the likelihood of processor’s preferring to add value to cashew kernel, and both cashew products as against cashew nut for any unit increase in these variables. This study provided vital insights about how the relative significance of these factors will aid policy analysts and decision-makers to determine which of the factors to focus on while developing specific policies for the cashew value chain industry.
Drag force through gases and plasma
Authors: M Apostol
Published: February 2022

The drag force in a gas (previously derived by Stokes and Rayleigh) is derived by means of the molecular kinetics (transport equation of the momentum). Two regimes of resistance to motion are identified, governed by the relation of the velocity to the thermal (molecular) velocity. They correspond to the molecular movement, for small velocities, or to the hydrodynamic motion for high velocities. In the former case sound waves are not excited, and energy is dissipated by viscosity (friction), while in the latter case the energy is dissipated by the excitation of the sound waves. Also, the treatment is applied to the plasma. It is shown that in usual plasmas it is unlikely that the body motion excites plasmons.
Managing vomiting in the third trimester of pregnancy during fixed prosthodontic treatment. A case report and review of the literature
Authors: Spyridon Stefos , Theodor Stefos
Published: February 2022

Pregnancy is a specific and critical period in a woman’s life. Some pregnant women face difficulty when performing effective oral hygiene care due to pregnancy-related vomiting symptoms. A hypersensitive vomit reaction in the third trimester of pregnancy is not frequent and may prevent the dental provider from successfully completing critical clinical stages resulting in poor treatment outcomes. Once pregnant women suffer an unpleasant gag reflex experience in a dental office, they may become phobic, delaying or postponing their dental treatment. The purpose of this article is to report a case of a 32-year-old woman, primigravida in the third trimester of pregnancy (32 weeks), partially edentulous with an exaggerated vomiting reaction, focusing on successful clinical management using a simple but effective table salt technique and proper fixed prosthesis design, as also to discuss the etiology, clinical symptoms and consequences of vomiting associated with late pregnancy during the dental, especially prosthodontics , treatment in such cases.
Southern transect resurvey 2022 v1
Authors: Ponisio Lauren
Published: February 2022

This protocol details the Ponisio Lab's collecting protocol for the 2022 Moldenke re-survey of the southern transect. Each site consists of two 900m long transects, marked every 100m with flagging tape and a nail. Each transect has three 10m² vegetation plots set ~10 m off at the beginning, middle and end of each transect. At some sites this placement of vegetation plots was not possible due to terrain so site maps/GPS points should be referenced. During a site visit passive traps are placed on one transect, and active netting and vegetation surveys are done on the other transect. The activities associated with each transect alternate every site visit.
