Exploring Secondary-school EFL Teachers’ Perception and Practices of Formative Assessment
Authors: Sulastini Sri 
Published: September 2023

Formative assessment is critical to effective classroom instruction and is widely acknowledged as a positive ‘facilitator’ of student learning and its careful implementation has powerful, positive effects on learning. This implies requirements for teachers to have an appropriate level of language assessment literacy or LAL since the effectiveness of teachers’ practices is much influenced by their perceptions or beliefs and related experiences. This study aims at obtaining better insights into English Foreign Language (EFL) teachers’ perceptions and practices of formative assessment. For this purpose, ninety-two EFL teachers of General and Vocational Secondary Schools in Jakarta and Bogor areas were involved as subjects of the study. The findings of the study reveal that teachers may not fully comprehend what FA is. This is reflected in the significant inconsistencies in their responses to the given questionnaires and interviews that suggest a misconception of FA. More rigorous study with better methodology is recommended as follow-up actions. In addition, the findings generate an urgent call for EFL teacher education programs to devise relevant professional development programs that can meet the actual needs of preset and inset program participants.
Low-Salinity Polymer Flood for Enhanced Oil Recovery in Low-Permeability Carbonates

Published: September 2023

Summary
Low-salinity waterflooding and brine ion modification, in general, can improve displacement efficiency in initially oil-wet reservoirs if it can alter wettability, but it is often a slow process. Polymer flooding usually does not improve displacement efficiency (without significant viscoelasticity) but enhances sweep efficiency. The main objective of this work is to study the synergy between ion modification and polymer flooding for low-permeability carbonate rocks. High-salinity high-temperature reservoirs often need a sulfonated polymer for thermal stability in the high-salinity brine, but a low-salinity water (LSW) injection at that temperature can use a common hydrolyzed polyacrylamide (HPAM) polymer. The second objective of this study is to compare the performance of these two polymer injections. With the proper preparation method, two polymers (HPAM and AN132) with the molecular weight of approximately 6 MDa were successfully injected into the oil-aged carbonate rocks with the absolute permeability of 10–20 md. A low-salinity polymer (LSP) flood was carried out using HPAM prepared in diluted seawater (with added sulfate concentrations). High-salinity polymer (HSP) floods increased the oil recovery in tight cores by 4–5% original oil in place (OOIP) due to higher pressure gradient. Low-salinity corefloods (with added sulfate ions) produced little incremental oil in a few pore volumes (PVs) of injection, but the combination of sulfated low-salinity brine and polymer improved the oil recovery by 8–10% OOIP in less than 1.5 PV. It is shown for the first time that the low-salinity brine with additional sulfate and negatively charged HPAM polymer changed the wettability of the originally oil-wet carbonate rock to water-wet. The synergy between polymer and wettability alteration can recover oil from bypassed pores and shorten the time for oil recovery.

Abstract
The milk clotting proteases have the specificity of hydrolyzing the k-casein fraction of milk casein micelles. In this study, the biochemical characterization and coagulation potential of a new milk coagulant derived from the enzymatic extract of Penicillium camemberti 0798400075 through solid state fermentation (SSF) using coffee husks are investigated. The caseinase produced showed low proteolytic activity (0.076 U/mL) and high coagulant activity (8 ACL/mL and 10 ACL/mL) for powdered and whole UHT milk, respectively, and reached optimal temperature at 50 ºC and optimal pH at 7, remained with 80% of its activity at 40 ºC, showed greater affinity for acidic conditions, containing more than 60% of its activity at pH 5.0 and exhibited an increase in its activity in the presence of Mg2+ ions. The new coagulant showed potential to be used as a substitute for rennet in the coagulation process of milk caseins.

Abstract
Previous studies have demonstrated that schwertmannite (Sch) exhibits good adsorption performance for Cr(VI). In order to further enhance the ability to remove Cr(VI), this study prepared a novel composite (Fe(II)@Sch) by embedding ferrous iron (Fe(II)) on Sch. The adsorption performance of Cr(VI) on Fe(II)@Sch was investigated by batch adsorption experiments, and a possible removal mechanism was proposed through characterization analysis. The results showed that the optimal Fe/Sch ratio for Fe(II)@Sch preparation was 120 mmol/g. Fe(II)@Sch enabled efficient and rapid adsorption of Cr(VI). The maximum Cr(VI) adsorption capacity of Fe(II)@Sch was 4.17 mmol/g at pH 6.0, which was 69% higher when compared to Sch, and 81% of the maximum adsorption could be achieved within 1 min. The embedding of Fe(II) led to a decrease in the particle size and an increase in the specific surface area (SSA) of Sch, which could be considered favorable for adsorption. After four repeated cycles 93.3% of the original Cr(VI) adsorption capacity was still maintained. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy analysis showed that the interaction between Fe(II)@Sch and Cr(VI) followed an adsorption-reduction mechanism. The results demonstrated that Fe(II)@Sch could be used as an effective material for removing Cr(VI) from wastewater.

Abstract
Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri, is responsible for significant economic losses of citrus in Brazil and elsewhere. The disease occurs in all regions of commercial production of sweet orange (C. sinensis L. Osbeck). Compared to chemical control, deploying canker-resistant cultivars is a viable and economical alternative for management of the disease. The objectives of this study were to compare the resistance to citrus canker of 14 genotypes of sweet orange, and to verify the levels of various enzymes involved in the canker resistance response, specifically peroxidase, catalase, and superoxide dismutase. The 14 genotypes included were Hamlin, Vermelha, Pera EEL, Pera IAC, Pera Bianchi/CC, Pera Ipiguá, Pera IAC 2000/1, Pera Ovale Siracusa, Pera Ovale, Pera IAC 2000/2, Pera M5, Pera Arapongas, Pera 58 and Pera 59. The varieties were evaluated under greenhouse conditions, through inoculation of leaves with X. citri subsp. citri, strain Xcc 306. After inoculation, measurements of lesion diameter and biochemical analyses were performed. Significant differences in resistance to X. citri subsp. citri between the citrus genotypes were observed, with cultivars Pera IAC and Pera EEL having significantly or numerically the smallest diameter canker lesions. Cultivar Pera IAC showed elevated levels of peroxidase, catalase and superoxide dismutase, enzymes known to be involved in resistance response to pathogen invasion. Cultivars with a strong resistance response to infection, and that produce smaller lesions are likely good candidates for commercial production or for use in breeding programs.

Authors: Zhao Shangyi , Guo Ming 
Published: September 2023

Abstract
Soft computing technology has attracted extensive attention in the fields of computer engineering and automatic control because it can deal with uncertainties, fuzziness and complex practical problems. In order to realize the cooperative optimization of electric vehicle's dynamic performance and economic performance, this paper adopts Genetic Algorithm (GA) in soft computing technology. The advantage of soft computing technology lies in its adaptability to uncertainty, fuzziness and complex practical problems, which makes GA an effective tool to solve complex optimization problems. Firstly, the power system structure and energy management strategy of electric vehicles are investigated and analyzed. Then, the improved non-dominated sorting genetic algorithm II (NSGA-II) is selected to optimize the parameters of electric vehicles because of its simple operation and high optimization accuracy. Then, NSGA-II is used to construct the power and energy configuration of electric vehicles, with power performance and economic performance as the main optimization objectives. Finally, in order to achieve the optimization goal, the relevant variables are selected, and the optimization objective function and constraint conditions are established, and the model is simulated and evaluated. The results show that the acceleration time of the optimized electric vehicle is significantly reduced, the dynamic performance is improved by more than 7%, and the power loss is reduced by 5%. In addition, compared with the current multi-objective optimization model, this model enables electric vehicles to travel longer distances under the same power. These findings provide valuable reference for the performance improvement of electric vehicles in intelligent manufacturing.

Published: September 2023

Abstract
Background
Diabetic Retinopathy (DR) is a leading cause of blindness worldwide, affecting people with diabetes. The timely diagnosis and treatment of DR are essential in preventing vision loss. Non-mydriatic fundus cameras and artificial intelligence (AI) software have been shown to improve DR screening efficiency. However, few studies have compared the diagnostic performance of different non-mydriatic cameras and AI software.
Methods
This clinical study was conducted at the Endocrinology clinic of Akdeniz University with 900 diabetes patients who had not been diagnosed with DR but had diabetes already diagnosed. Fundus images of each patient were taken using three non-mydriatic fundus cameras without dilation, and EyeCheckup AI software was used to diagnose mtmDR, vtDR, and CSDME. The patients underwent dilation and 4-wide field fundus photography, and three retina specialists graded the images according to the Diabetic Retinopathy Treatment Preferred Practice Patterns of the American Academy of Ophthalmology. The study was pre-registered on clinicaltrials.gov with the ClinicalTrials.gov Identifier: NCT04805541.
Results
The Canon CR2 camera had an mtmDR diagnosis sensitivity and Specificity of 95.65% / 95.92%, the Topcon NW400 had 95.19% / 96.46%, and the Optomed Aurora had 90.48% / 97.21%. For vtDR, the Canon CR2 had a sensitivity and Specificity of 96.00% / 96.34%, the Topcon NW400 had 98.52% / 95.93%, and the Optomed Aurora had 95.12% / 98.82%. For CSDME, the Canon CR2 had a sensitivity and Specificity of 95.83% / 96.83%, the Topcon NW400 had 98.50% / 96.52%, and the Optomed Aurora had 94.93% / 98.95%.
Conclusion
These results demonstrate the potential of non-mydriatic fundus cameras and EyeCheckup software for diagnosing diabetic retinopathy. Each camera brand had varying degrees of sensitivity and Specificity. The Canon CR2 had the highest sensitivity and Specificity for mtmDR and vtDR, whereas the Topcon NW400 had the highest sensitivity and Specificity for CSDME. These findings suggest that clinicians should consider camera brand when selecting a screening tool for DR. Further studies are needed to confirm these results and investigate other factors affecting DR screening efficiency.

Published: September 2023

Abstract

Introduction:Snakebite is a public health problem leading to about 55,000 deaths every year in India. Kidney injury subsequent to snakebite envenomation is common ( reported prevalence is up to 32%). The current study aims to elucidate the spectrum of kidney histopathology in acute kidney injury (AKI) cases followed by snake bites.Methods:We searched seven electronic database studies to identify studies describing the histopathological findings in the kidney with snakebite envenomation. Two reviewers independently conducted titles and abstract screening as well as full-text evaluation for the final inclusion decision. Data were extracted as per a standardized form and conducted narrative synthesis. Studies done exclusively on autopsy findings, in vitro studies, and case reports were excluded.Results:We retrieved 1810 studies and finally included 28 studies which met the eligibility criteria in the analysis. Most studies were single-centre and the majority were cross-sectional. Overall we included a total of 534 renal biopsies. Russell's viper bite was the commonest cause related to AKI. Acute tubular necrosis was the most common finding followed by acute interstitial nephritis, acute cortical necrosis, and thrombotic microangiopathy. Vasculitis changes in vessels were rarely reported. The clinical presentation and prognosis of the patients were directly proportional to the severity of the renal histopathological lesion.Conclusion:This analysis supports the notion that renal biopsies are of utmost importance to guide prognosis and increase our knowledge about post- snake bite AKI pathophysiology
Dysregulation of extracellular matrix and Lysyl Oxidase in Ehlers-Danlos Syndrome Type IV skin fibroblasts
Authors: Foehr Reece , Anderson Keith , Dombrowski Owen , Foehr Anna , Foehr Erik 
Published: September 2023

Abstract
Background
Ehlers-Danlos syndrome Type IV (aka Vascular Ehlers Danlos, or vEDS) is a dominantly inherited mutation in the Collagen 3A1 gene (COL3A1). The disease is characterized by tissue friability and age-related susceptibility to arterial aneurysm, dissection and rupture as well as uterine and bowl tares. These clinical manifestations result in major surgical intervention and decreased life expectancy. Understanding how mutations in COL3A1 impact the structure and function of the extracellular matrix is important to managing the disease and finding treatments.
Results
Skin fibroblasts from vEDS subjects and normal individuals were cultured and studied. Proteomics analysis identified dozens of upregulated proteins related to extracellular matrix dysregulation that is characteristic of fibrosis. Gene expression libraries from cultured primary fibroblasts were screened for messenger RNA (mRNA) markers of ECM degradation. The proteomics and targeted gene expression array results were largely consistent with dysregulation of the extracellular matrix in vEDS. The data show upregulation of multiple Collagen proteins and genes, other ECM components, and enzymes related to ECM processing and turn-over. vEDS fibroblasts expressed significantly more cross linked C-Telopeptide of Collagen III (CTXIII) than normal fibroblasts, indicative of Collagen III degradation and turn-over. Further, the expression and activity of Lysyl Oxidase (LOX), an enzyme that initiates covalent cross-linking of soluble collagen and elastin into protease resistant fibers, is elevated in vEDS fibroblasts compared to normal fibroblasts.
Conclusion
Together, these findings suggest dysregulated ECM deposition and processing, reminiscent of a state of fibrosis. Therapeutics that target the dysregulated ECM proteins or help replace damaged tissue may improve clinical outcomes.

Abstract
Background
The COVID-19 pandemic led to decline in access and utilization of the baby-friendly community initiative (BFCI) which is being implemented in Kenya. The impact of the pandemic on the BFCI and on maternal and child health and nutrition has not been documented. We undertook a qualitative study that assessed the effect of the COVID-19 pandemic on the baby-friendly community initiative (BFCI) activities, maternal and child health (MCH) services and maternal, infant and young child nutrition (MIYCN) practices in Kenya.
Methods
Data on the impact of the pandemic on the BFCI activities, provision and access to MCH services and MIYCN practices were collected using key informant interviews (n = 57), in-depth interviews (n = 31), and focus group discussions (n = 15) with government officials, civil society organizations and community members in BFCI implementing and non-implementing urban and rural areas.
Results
Our study found that BFCI activities, such as home visits, support group meetings and MCH services such as nutrition counselling, growth monitoring and vaccination were interrupted by the pandemic due to fear of contracting the virus, lack of personal protective equipment (PPEs) and movement restrictions. This meant that mothers did not have access to basic community and health services. Food insecurity attributed to financial difficulties resulted in coping strategies such as skipping meals and negatively affected MIYCN practices. Positive measures to prevent COVID-19 spread such as remote working enabled some mothers to adequately feed their children because they were better able to balance working and the demands of feeding young children from home.
Conclusion
On balance, the pandemic negatively impacted the BFCI, MCH services and MIYCN practices in Kenya. In such a context, there is a need for innovative approaches to ensure continued provision of and access to facilities and community health services in the future if the country finds itself in a similar position with the challenges of a pandemic. The pandemic revealed that remote working support policies could have the potential to improve breastfeeding and complementary feeding for working women but further evidence is needed to fully evaluate this.
Tuning the properties of polycaprolactone-based fibers by using polyethylene oxide / polycaprolactone block copolymers
Authors: Cárdenas Verena , Fernández Daniel , Romero-Araya Pablo , Werlinger Francisca , Martínez Javier , Moreno-Villoslada Ignacio , Flores Mario Flores 
Published: September 2023

Abstract
Polymers bearing hydrolyzable groups such as polyesters are a source of raw materials to prepare common and specific materials, due to their degradability properties under mild conditions; for instance, poly(ε-caprolactone) (PCL) is a broadly used polymer in electrospinning to produce fibrous and degradable materials. In this work, we explored the synthesis, characterization, and conditions to prepare fibrous materials made of different PCL homopolymers and PCL-PEO block copolymers possessing different molecular weights, which have been synthesized by ring-opening polymerization (ROP). The obtained polymers were characterized by FT-IR, 1H-NMR, and GPC. The synthesized polymers were used to prepare fibrous materials by the electrospinning method, which were characterized by SEM, wettability, tensile test, and DSC. We found that low molecular weight polymers cannot produce tangible materials; however, the addition of block copolymers containing the hydrophilic PEO unit produced porous materials where fiber diameter decreased, also tuning hydrophilic as the PEO chain length increased in the block copolymer. Thus, these materials can be projected towards specific applications, for instance, having a possible potential use in tissue engineering. The dual role of block copolymers in the fabrication of PCL fibers according to changes observed in materials by controlling both fiber size and hydrophilia is discussed.
Giant cell arteritis combined with venous sinus thrombosis: A case report and systematic review
Authors: Li Yangyang , Zhang Hanyu , Wang Guoxing 
Published: September 2023

Abstract
Background
Giant cell arteritis (GCA) is a low-incidence systemic vasculitis in Asian populations. It is considered a rare cause of cerebral venous sinus thrombosis (CVST). This case report presents a rare case of an Asian patient with GCA accompanied by CVST.
Case Presentation:
A 67-year-old man who had been experiencing varicose veins in the bilateral temporal region for four years and complete loss of vision in the right eye for four months sought medical attention in our emergency department due to loss of vision in the left eye for two weeks and fever for three days. On admission, this patient had a recurrent fever, and no source of infection was identified. Conventional anti-infective treatment was ineffective. Based on the clinical presentation, a diagnosis of GCA combined with CVST was made, and hormone therapy was administered. The patient was discharged with normal body temperature, clear consciousness, recovery of vision in both eyes, and improved clinical parameters.
Conclusions
This case report presents a distinct manifestation of both GCA and CVST. The coexistence of GCA and CVST is not solely attributed to increased blood viscosity, inflammation of the vascular wall, and abnormal coagulation. It also involves a complex immunological network. This case report may help clinicians make comprehensive clinical decisions in similar cases.
