Published: July 2021

Cyclone separator is equipment used to control emissions from gas flow in industrial processes. The principle of removing particulates from the gas flow in this tool is to use the centrifugal force. The centrifugal force generated from the rotating flow will make dust particles wasted into the cyclone wall where the dust will then fall into the hopper. Adsorption is a series of processes for the accumulation of a substance (adsorbate) on the surface of another substance (adsorbent). Adsorption can occur because of the energy on the surface and the attraction force on the surface. This study aims to obtain a good CO2 adsorption efficiency from modifying the cyclone separator using an adsorption column, analyzing the CO2 gas adsorption process produced from the biomass system at the utility unit boiler station at the Palm Oil Mill (PMO) using a modified cyclone. This simulation was carried out using the Autodesk Inventor Professional 2017 (Student Version) application for the descripction of the tool as a preprocessor and Ansys 2019 R3 (Student Version) applications as a processor and post processor. The variations that were applied included the adsorption column bed height of 3100 mm and 4650 mm, respectively, CO2 gas flow rates of 10, 12.5, 15, 17.5, 20, 22.5 dan 25 m/s and mass loading 0,001 kg/s. The results obtained in the most optimal modification of the cyclone separator are at a bed height of 3100 mm with the highest adsorption percentage 93.437%, the highest flow 91.974% with a pressure drop of 1000 Pa.

Published: July 2021

Some materials derived from plants can be used as a source of biodegradable thermoplastic materials such as rice, potatoes, corn, sweet potatoes, sago, etc. In this research, thermoplastic sago starch (TPS) with a mixture of two types of fillers was synthesized to become environmentally friendly composites that can be naturally degraded in a relatively short time compared to other conventional plastics which decompose in decades, hence can contribute to environmental conservation efforts. Increasing the strength of bio composite through the presence of fillers will expand its application such as for household application. Sago is available in large quantities in Indonesia and needs to be utilized optimally to increase its added value. TPS is synthesized using sorbitol as a plasticizer so that it becomes a starch paste. Composites are moulded by means of compression moulding using TPS and cellulose as a filler and Polypropylene (PP). The fillers used were sawdust and rice husk with several variations to obtain optimal combination, to improve the mechanical performance of the composites. For rice husk fibre, the highest tensile strength value 13.82 MPa, found at 40% fibre with ratio of TPS: PP 1: 0.5, and the highest elongation value was 16.47% at 40% fibre at ratio of TPS : PP 1: 0.5. For Sawdust fibre, the highest tensile strength value 11.08 MPa, obtained at 20% fibre at ratio of TPS : PP 1 : 1, and the highest elongation value was 18.57% at 20% fibre with ratio of TPS : PP 1 : 1. Type of filler has different effect on the tensile strength and elongation of the bio composite,

Background:The degree of heterotypic immunity induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains is a major determinant of the spread of emerging variants and the success of vaccination campaigns, but remains incompletely understood.Methods:We examined the immunogenicity of SARS-CoV-2 variant B.1.1.7 (Alpha) that arose in the United Kingdom and spread globally. We determined titres of spike glycoprotein-binding antibodies and authentic virus neutralising antibodies induced by B.1.1.7 infection to infer homotypic and heterotypic immunity.Results:Antibodies elicited by B.1.1.7 infection exhibited significantly reduced recognition and neutralisation of parental strains or of the South Africa variant B.1.351 (Beta) than of the infecting variant. The drop in cross-reactivity was significantly more pronounced following B.1.1.7 than parental strain infection.Conclusions:The results indicate that heterotypic immunity induced by SARS-CoV-2 variants is asymmetric.Funding:This work was supported by the Francis Crick Institute and the Max Planck Institute for Dynamics of Complex Technical Systems, Magdeburg.

Published: July 2021

Pineapple farming is among the fastest-growing agricultural sub-sectors in Homa Bay County, Kenya specifically Rangwe sub-county. However, limited attention has been given to the market access of this produce. Evidenced by vast quantities of pineapples harvested from the farms and stacked along main highways without targeting a specific market. This result to a small portion being sold and the rest deteriorating, consequently reducing returns for pineapple agripreneurs. Therefore, this paper sought to determine those factors that influences access to formal market by pineapple agripreneurs and as well as find out challenges of and opportunities for accessing formal markets by the Rangwe pineapple agripreneurs. The survey was undertaken in Rangwe Sub-county, and multisampling method was used to select a sample of 183 pineapple agripreneurs from the study area, primary data was collected using a semi-structured survey tool. Data was analyzed by descriptive analysis and Logistic regression model. Results indicated that pineapple agripreneurs were faced with numerous challenges in accessing pineapple market, also there existed several market access opportunities for pineapple agripreneurs. The results of logistic regression analysis revealed extension contacts, education level and price of pineapple as factors that were positively and statistically significant in influencing access to formal markets. While those that were statistically and negatively influencing access to formal market comprised of; age of household head, household size, and type of road. The study recommends; improvement of road infrastructure in pineapple producing areas so as to improve on their market access; development of policies that encourages capacity building of pineapple agripreneurs in Rangwe sub-county
COMP Report: An updated algorithm to estimate medical physics staffing levels for radiation oncology
Authors: Malkoske Kyle E. , Sixel Katharina E. , Hunter Robert , Battista Jerry J. 
Published: July 2021

AbstractPurposeMedical physics staffing models require periodic review due to the rapid evolution of technology and clinical techniques in radiation oncology. We present an update to a grid‐based physics staffing algorithm for radiation oncology (originally published in 2012) that has been widely used in Canada over the last decade.Materials and MethodsThe physics staffing algorithm structure was modified to improve the clarity and consistency of input data. We collected information on clinical procedures, equipment inventory, and teaching activities from 15 radiation treatment centers in the province of Ontario from April 1, 2018, to March 31, 2019. Using these data sets, the algorithm's weighting parameters were adjusted to align the prediction of full‐time equivalent (FTE) personnel with actual staffing levels in Ontario. The algorithm computes FTE estimates for medical physicists, physics assistants, engineering (electrical and mechanical), and information technology (IT) support. The performance of the algorithm was also tested in eight Canadian cancer centers outside of Ontario.ResultsThe mean difference between the algorithm and actual staffing for the 23 Canadian cancer centers did not exceed 0.5 FTE for any staffing group. The results were slightly better in Ontario than in other provinces, as expected since the algorithm was optimized using Ontario data. There was a linear correlation between the algorithm predictions and the number of annual‐treated cases for physicists, and physicists plus physics assistants. For other staff categories, the algorithm weighting parameters were not significantly altered, except for a reduction in mechanical engineering staff. Comparison with other published models suggests that the updated algorithm should be considered as a minimum recommended staffing level for the clinical support of radiation oncology programs.ConclusionsWe support the use of grid‐based physics staffing algorithms that account for clinical workload with flexibility to adapt to local conditions with variable academic and research demands.
Mere exposure to dialogic framing enriches argumentive thinking
Authors: Kuhn Deanna , Modrek Anahid 
Published: July 2021

SummarySixty college students either read a script of a dialog between two individuals holding contrasting positions on the issue of U.S. immigration or read texts containing their two individual position statements on the issue, expressing their same respective views. With this material removed from view, participants expressed in writing their own views on the issue. We asked whether exposure to the dialogic framing would have a greater effect on argumentive thinking, compared to non‐dialogic presentation of the same arguments. Essays of the two groups differed in several ways. The dialog group showed greater investment in the task by writing more. Additionally, 78% of the dialog group (vs. 48% of the individual‐position control group) made reference to the views they had read, despite no instruction to do so, over half referencing them in a comparative way (vs. 21% of the control group). The substance of the essays showed richer thought by the dialog group, including more “However” clauses (connecting two opposing statements) and more meta‐level statements about the issue itself, supporting the hypothesis of a benefit of dialogic framing. Theoretical and educational implications are considered.

Published: July 2021

AbstractNanoscale materials have unique properties that make them especially useful for biomedical diagnostic applications. Recent developments in nanoengineering have resulted in increasing use of nanostructures in biosensors. Various types of 0D, 1D, 2D, and 3D nanostructures have been used to improve biosensor sensitivity, selectivity, limit of detection, and time to result, among other metrics. These nanostructures have been integrated into electrochemical, optical, and other biosensors for this purpose. Here, the most recent advances in the use of nanostructured materials in biosensors are described. This includes a discussion of nanoparticles, nanorods, nanofibers, nanopillars, nanowires, nanosheets, indented nanopatterns (nanoholes and nanoslits), nanogaps, nanochannels, nanopores, nanofunctionalized surfaces, and complex hierarchical structures and their unique advantages and applications in biosensors. Clinical applications of these nanobiosensors are also highlighted along with a discussion of the future directions for these materials in diagnostics.

Published: July 2021

AbstractAlthough sodium–sulfur (Na–S) batteries present the great prospects of high energy density, long cyclability, and sustainability, their deployment is heavily encumbered by safety, practicality, and versatility issues engendered by their high operating temperatures above 300 °C. Lowering the operating temperatures impedes the performance of Na–S batteries due to the formation of insulating S/polysulfides, diminished Na ion conduction in the β”‐alumina solid electrolyte (BASE), the Na metal dendrite growth at temperatures below its melting point, and the shuttle effect occurring in the absence of the BASE. Herein, a Na–S battery that integrates a dual electrolyte consisting of the BASE and a novel inorganic ionic liquid is proposed for intermediate‐temperature operations of 150 °C. Investigations reveal the ionic liquid to have high ionic conductivity, wide electrochemical window, and excellent thermal and chemical stability, making it propitious for intermediate‐temperature operations. The high reversible capacity of 795 mAh (g‐S)−1 at 0.1 mA (electrode area: 0.785 cm2) and an average capacity of 381 mAh (g‐S)−1 achieved over 1000 cycles at 0.5 mA validate the use of ionic liquids in dual electrolyte systems to improve Na–S performance.

Published: July 2021

AbstractWith the development of industrialization, environmental pollution problems (e.g., oily water discharge and oil spill accidents) are becoming increasingly severe. The efficient and economic treatments for oily sewage are urgently needed and remain a huge challenge. Here, a robust and durable superhydrophobic material with the contact angle above 160° is prepared by coating SiO2 particles/polythiophene on cotton fabrics through a sol–gel process and an oxidation coupling polymerization. The polythiophene/SiO2 coated cotton fabric displays excellent resistance to ultraviolet irradiation, high and low temperatures, acid and salt solution immersion, organic solvent immersion, and good mechanical abrasion durability, antidirt and antifrost properties. The modified fabric is successfully applied as a filter to separate oil–water mixtures by gravity with high separation efficiency and excellent reusability. Moreover, superhydrophobic absorbers can be easily prepared from common 3D porous materials such as a sponge wrapped with the modified fabric for the effective collection of oil. Both immiscible oil–water mixtures and emulsions (oil‐in‐water and water‐in‐oil) can be separated even under harsh conditions (acidic solution or artificial seawater). This work provides a facile and selectable solution to treat oily sewage and leads to new ways of efficient oil–water separation.
