The SPRT Sign Chart for Process Dispersion
Authors: Godase Dadasaheb G. , Mahadik Shashibhushan B. 
Published: September 2021

Abstract
A nonparametric sequential probability ratio test control chart to monitor the process dispersion based on the sequential sign statistic is proposed.
The statistical performance of this chart is evaluated by comparing it with that of the charts for dispersion based on sign statistic in the existing literature.
It is found that the proposed chart outperforms all these charts uniformly in detecting a shift of any size over a wide range.
An implementation of the chart is illustrated through an example.

Orange juice ultrafiltration: characterisation of deposit layers and membrane surfaces after fouling and cleaning
Authors: Abd-Razak Nurul Hainiza , Chew Y. M. John , Bird Michael R. 
Published: September 2021

Abstract
The influence of feed condition and membrane cleaning during the ultrafiltration (UF) of orange juice for phytosterol separation was investigated. UF was performed using regenerated cellulose acetate (RCA) membranes at different molecular weight cut-off (MWCO) values with a 336 cm2 membrane area and a range of temperatures (10–40 °C) and different feed volumes (3–9 L). Fluid dynamic gauging (FDG) was applied to assess the fouling and cleaning behaviours of RCA membranes fouled by orange juice and cleaned using P3-Ultrasil 11 over two complete cycles. During the FDG testing, fouling layers were removed by fluid shear stress caused by suction flow. The cleanability was characterised by using ImageJ software analysis. A Liebermann-Buchard-based method was used to quantify the phytosterol content. The results show that RCA 10 kDa filters exhibited the best separation of phytosterols from protein in orange juice at 20 °C using 3 L feed with a selectivity factor of 17. Membranes that were fouled after two cycles showed higher surface coverage compared to one fouling cycle. The surface coverage decreased with increasing fluid shear stress from 0 to 3.9 Pa. FDG achieved 80–95% removal at 3.9 Pa for all RCA membranes. Chemical cleaning using P3-Ultrasil 11 altered both the membrane surface hydrophobicity and roughness. These results show that the fouling layer on RCA membranes can be removed by fluid shear stress without affecting the membrane surface modification caused by chemical cleaning.
Isotonic saline causes greater volume overload than electrolyte-free irrigating fluids
Authors: Hahn Robert G. 
Published: September 2021

Abstract

Objectives
Systemic absorption of the irrigating fluid used to flush the operating site is a potentially serious complication in several types of endoscopic operations. To increase safety, many surgeons have changed from a monopolar to a bipolar resection technique because 0.9% saline can then be used instead of electrolyte-free fluid for irrigation. The present study examines whether the tendency for excessive plasma volume expansion is greater with saline than with electrolyte-free fluid.

Methods
Pooled data were analyzed from four studies in which a mean of 1.25 L of either 0.9% saline or an electrolyte-free irrigating fluid containing glycine, mannitol, and sorbitol was given by intravenous infusion on 80 occasions to male volunteers and patients scheduled for transurethral prostatic surgery. The distribution of the infused fluid was analyzed with a population volume kinetic model based on frequently measured hemodilution and the urinary excretion.

Results
Electrolyte-free fluid distributed almost twice as fast and was excreted four times faster than 0.9% saline. The distribution half-life was 6.5 and 10.6 min for the electrolyte-free fluid and saline, respectively, and the elimination half-lives (by urinary excretion) from the plasma volume were 21 and 87 min. Simulation showed that the plasma volume expansion was twice as great from 0.9% saline than from electrolyte-free fluid.

Conclusions
Isotonic (0.9%) saline expands the plasma volume by twice as much as occurs with electrolyte-free irrigating fluids. This difference might explain why signs of cardiovascular overload are the most commonly observed adverse effects when saline is absorbed during endoscopic surgery.

Abstract
This article has indicated optical coherent differential polarization (DP) 16 quadrature amplitude modulation (QAM) transceiver systems with free-space optical (FSO) channel in the presence of differential coding scheme. The optical coherent DP 16-QAM receiver executes the reverse process conversion of the optical signal into an electrical one that is detected to the users. The proposed optical coherent DP-16 QAM transceiver systems based FSO channel model with differential coding has been presented and compared with the previous model. However, the simulation results have confidence realization about the superiority of the proposed simulation model. Hence the proposed optical coherent DP-16 QAM transceiver systems simulation model with differential coding is verified and validated the enhancement performance based on simulation performance parameters.
Performance analysis of free space optical system incorporating circular polarization shift keying and mode division multiplexing
Authors: Meenu  , Sharma Anshu , Malhotra Rahul 
Published: September 2021

Abstract
In this work, a free-space optical (FSO) communication system with the integration of mode division multiplexing and circular polarization shift keying (CpolSK) is proposed at 2 × 40 Gbps using LG00 and LG01 modes. Effects of diverse weather conditions such as clear weather, light rain, moderate rain, heavy rain, thin fog, thick fog, and heavy fog are studied on system performance. Further, a detailed comparison of CpolSK and polarization shift keying (PolSK) is performed at different FSO lengths in terms of log bit error rate. For implementation, analysis, and comparison, Optiwave Optisystem software is used and results show that CpolSK covers 100 km link distance and PolSK limits to 90 km only. Also, LG00 mode performs better than LG01 mode under all weather instabilities in the proposed system.

Abstract

Objectives
Coronavirus disease 2019 has caused a major epidemic worldwide, and lockdowns became necessary in all countries to prevent its spread. This study aimed to evaluate the effects of staying-at-home practices on the metabolic control of children and adolescents with type 1 diabetes during the pandemic period.

Materials and Methods
Eighty-nine patients younger than 18 years old who were diagnosed with type 1 diabetes at least one year before the declaration of the pandemic were included in the study. The last visit data of the patients before and after the declaration of the pandemic, and the frequency of presentation of diabetes-related emergencies from one year after diagnosis of type 1 diabetes to the declaration of the pandemic, and from the declaration of the pandemic to the last visit after the pandemic declaration were compared.

Results
The total number of patients was 89, and 48 (53.9%) were boys. The mean (± standard deviation [SD]) age at diagnosis was 8.4 ± 3.7 years (boys 7.9 ± 3.6 years; girls 8.9 ± 3.9 years). There was no statistically significant difference when the SD values of the anthropometric measurements, and the glycosylated hemoglobin (HbA1c) and lipid profile tests were compared. However, the frequency of admission to the emergency service related to diabetes was significantly different.

Conclusions
Although the pandemic did not significantly affect the metabolic and glycemic controls of the children with type 1 diabetes included in this study, an increase in the frequency of diabetes-related emergency admissions was noted.
Translation, transcultural remembrance and pandemic: a covert transediting of the Great Influenza memory for lessons to combat COVID-19 in Chinese online media
Authors: Hou Song , Yuan Mingming 
Published: September 2021

Abstract
This paper examines translation and transcultural remembrance of the 1918–19 Great Influenza or the more often yet mistakenly called “Spanish flu” for lessons to combat COVID-19 in Chinese online media. It presents a case study of “covert transediting” in the Shanghai Observer, i.e., a journalistic opinion that interweaves Chinese renderings of selected excerpts from four British and American media texts. With an integrated approach to travelling memory (Erll, Astrid. 2011. Travelling memory. Parallax 17(4). 4–18) via transediting, our analysis shows that the transeditor does not only choose source texts in terms of media and content, but also selectively reframes the “Spanish flu” memory for lesson learning in conjunction with the mainstream Chinese discourse and practice of COVID-19 control. It unveils how the Great Influenza is thus transculturally remembered in more simplified and ideologically agreeable manners through omission, summary translation, and transformation, while faithful transference is not sheerly dispensed. We contend that transcultural remembrance via transediting is a purposive, socio-culturally shaped practice involving interrelations and interactions of manifold factors, and we need a more complex approach to the politics of memory in translation. Journalistic translation, which is mostly covert and transediting, is among different genres of translation that shape transcultural memory; more research in their interplay is called for.
Effects of non-ionizing electromagnetic fields on flora and fauna, Part 3. Exposure standards, public policy, laws, and future directions
Authors: Levitt B. Blake , Lai Henry C. , Manville Albert M. 
Published: September 2021

Abstract
Due to the continuous rising ambient levels of nonionizing electromagnetic fields (EMFs) used in modern societies—primarily from wireless technologies—that have now become a ubiquitous biologically active environmental pollutant, a new vision on how to regulate such exposures for non-human species at the ecosystem level is needed. Government standards adopted for human exposures are examined for applicability to wildlife. Existing environmental laws, such as the National Environmental Policy Act and the Migratory Bird Treaty Act in the U.S. and others used in Canada and throughout Europe, should be strengthened and enforced. New laws should be written to accommodate the ever-increasing EMF exposures. Radiofrequency radiation exposure standards that have been adopted by worldwide agencies and governments warrant more stringent controls given the new and unusual signaling characteristics used in 5G technology. No such standards take wildlife into consideration. Many species of flora and fauna, because of distinctive physiologies, have been found sensitive to exogenous EMF in ways that surpass human reactivity. Such exposures may now be capable of affecting endogenous bioelectric states in some species. Numerous studies across all frequencies and taxa indicate that low-level EMF exposures have numerous adverse effects, including on orientation, migration, food finding, reproduction, mating, nest and den building, territorial maintenance, defense, vitality, longevity, and survivorship. Cyto- and geno-toxic effects have long been observed. It is time to recognize ambient EMF as a novel form of pollution and develop rules at regulatory agencies that designate air as ‘habitat’ so EMF can be regulated like other pollutants. Wildlife loss is often unseen and undocumented until tipping points are reached. A robust dialog regarding technology’s high-impact role in the nascent field of electroecology needs to commence. Long-term chronic low-level EMF exposure standards should be set accordingly for wildlife, including, but not limited to, the redesign of wireless devices, as well as infrastructure, in order to reduce the rising ambient levels (explored in Part 1). Possible environmental approaches are discussed. This is Part 3 of a three-part series.

Published: September 2021

Abstract
Novel sugar-based gemini surfactants with a 1,3-propan-2-ol spacer (1, 3-(N- alkyl-2-D-glucosaminyl acetyl) propan-2-ol, Glu(n)-3(OH)-Glu(n), n = 12, 14) were synthesized with D-(+)-glucono-1,5-lactone as starting material in two steps, whose structures were confirmed using proton nuclear magnetic resonance spectroscopy (1H NMR) and carbon nuclear magnetic resonance carbon spectroscopy (13C NMR). The micellization of Glu(n)-3(OH)-Glu(n) (n = 12, 14) in aqueous solution at 25.0°C was investigated by using surface tension measurement. The results show that the critical micelle concentration (CMC) of Glu(12)-3(OH)-Glu(12) is around 10–5 mol × L–1, and is one order of magnitude smaller than that of Glu(14)-3(OH)-Glu(14), indicating that the surface activity of Glu(12)-3(OH)-Glu(12) is superior to that of Glu(14)-3(OH)-Glu(14). Moreover, the aggregation behavior of Glu(12)-3(OH)-Glu(12) in aqueous solution at different pH values was investigated by surface tension, dynamic light scattering (DLS), and cryogenic transmission electron microscopic (Cryo-TEM) measurements. The results indicate that the CMC slightly increases with the decrease of the solution pH. The microstructure of Glu(12)-3(OH)-Glu(12) aggregates transitions from micelle to vesicle with the solution pH from acidic to neutral and alkaline. The microstructural transformation of Glu(12)-3(OH)-Glu(12) with the solution pH is mainly determined by the protonation of the two tertiary amine nitrogen atoms in its hydrophilic headgroups.
Weakening of the Transdermal Effect of p-Phenylenediamine Pigments by the Temperature-Sensitive Poloxamer Sodium Alginate Gel
Authors: Gao Haiyan , Zhou Yue , Wang Jianguo , Xu Hujun 
Published: September 2021

Abstract
A temperature-sensitive hair dye was prepared with a poloxamer-sodium alginate mixture. When the hair dye was applied to the hair (< 32 °C), it retained its flow dynamics. The hair dye was able to undergo a phase change and formed a solid as soon as it touched the scalp (32°C), which reduced the transdermal amount of p-phenylenediamine (PPD) and also adverse effects and toxicity. Compared to a conventional hair dye, the temperature-sensitive hair dye achieved a reduction of the transdermal amount of p-phenylenediamine by almost 65% at different concentrations. At the same time, the colouring effect was not significantly reduced. The poloxamer alginate hydrogel can be used as a novel colouring material to reduce the harm of the dye intermediate to the human body when colouring hair.

Bacteria BSR 2, Pseudomonas alcaligenes (BSR 3), Brevibacillus parabrevis (BSR 8), Brevibacillus sp. (BSR 9), isolated from termite gut and Bacillus licheniformis (BSA B1) isolated from milkfish gut have been known to possess celluloytic activity. However, their lignolytic ability has not been known. This study aimed to determine the lignolytic ability of bacteria isolated from termit (Coptotermes sp.) and milkfish (Chanos chanos Forsskal, 1775) guts and their enzymes characterization. The qualitative test was done through the spot test method, while quantitative assay was performed spectrophotometrically at 335 nm to calculate vanillin concentration. The isolates were grown in Lignin Mineral Medium, then the optical density (OD620) were measured every 24 hours for 5 days using spectrophotometer to determine their growth profile and the best isolation time of the lignolytic enzyme. Based on results, the best lignolytic enzyme isolation time for strains Bacillus licheniformis (BSA B1) and BSR 2 were 5 days, yielding lignolytic enzyme activity of 0.961 Â± 0.168 U/mg and 2.176 Â± 0.088 U/mg respectively, Â while strains Pseudomonas alcaligenes (BSR 3), Brevibacillus parabrevis (BSR 8), and Brevibacillus sp. (BSR 9) were 4 days, yielding of 1.206 Â± 0.045 U/mg, 1.162 Â± 0.191 U/mg, and 0.896 Â± 0.108 U/mg, respectively. The strain BSR 2 showed the highest lignolytic activity compared to other strains. The optimum temperature for lignolytic enzyme activity of BSR 2 was 30 â„ƒ and the optimum pH was 7. The lignolytic enzyme activity showed that these bacterial isolates can be a chance to be used as new alternative lignolytic enzyme source in commercial bioconversion process.

Sodium nitrite (NaNO2) found in vegetables, drinking water, and cured meats, can damage tissue because it is an oxidant. Plant phytochemicals such as quercetin are antioxidants. This study aimed to determine the potential of red okra pods ethanol extract (ROE) to repair kidney damage in mice (Mus musculus) induced by NaNO2. The red okra pods were extracted three times with saturated ethanol. The experiment used 36 male BALB/c mice aged 6-8 weeks and body weight of about 28 g. There are six research groups, namely, normal control, negative control (exposure to NaNO2 50 mg/kg BW), treatment of exposure to NaNO2 and administration of ROE at doses of 25, 50, 75, and 100 mg/kg BW. Sodium nitrite and ROE were given daily for 23 days by gavage. On day 24, the serum was isolated. Blood urea nitrogen (BUN) and creatinine (Cre) levels are measured to assess kidney function, as well as measuring the oxidant malondialdehyde (MDA) and the antioxidant enzyme of superoxide dismutase (SOD). The kidneys were made histological preparations and analyzed on the proximal convoluted tubule (PCT).Â All data were statistically analyzed (Î±=0.05). This study indicated that the administration of ROE at a 100 mg/kg BW dose is the most optimal in repairing damage to the PCT with increased normal cells and reduced necrosis. Besides, it degraded BUN, Cre, and MDA levels in the serum of mice exposed to NaNO2 compared to the other treatments. All doses of ROE promoted the SOD level. ROE restore kidney tissue, especially on PCT to normal. Kidney damage due to exposure to NaNO2 preservatives can be reduced by administering ROE. ROE prevents kidney damage through an increase in antioxidant enzymes. ROE can be used as a food ingredient as a source of antioxidants, thereby reducing the impact of oxidant compounds.

Published: September 2021

In silico is the more comprehensive and applicable approach in supporting, both conservation and breeding programs of germplasm. The study aimed to analyze and determine the genetic diversity and relationships of 24 species of Phalaenopsis using two DNA barcoding markers, namely the rbcL and trnL-F, by in silico approach. All sequences of these markers were collected randomly from the NCBI website and analyzed using several softwares and methods, such as ClustalW and MultAlin for multiple sequence alignments and MEGA-X to determine its genetic diversity and relationships. Specifically, the genetic diversity was determined using a nucleotide diversity index and their relationships by the Maximum Likelihood method. The results showed that Phalaenopsis has a low genetic diversity of 0.24, 0.32, and 0.19, respectively. The phylogenetic analysis revealed that this orchid separated into five (for the rbcL), six (trnL-F), and seven clades (a combined one), where the closest relationship is shown by P. amboinensis vs. P. venosa, whereas the farthest by P. gibbosa vs. P. doweryensis, P. stuartiana vs. P. micholitzii, and P. celebensis vs. P. pulchra. The results have novel information on the diversity and relationships of Phalaenopsis on the in silico approach. Thus, our findings might be used in supporting the conservation and breeding program of Phalaenopsis, both locally and globally.
