Published: June 2021

Background and Purpose: Mathematical modelling competency is one of the vital characteristics in mathematics education. Educational researchers have updated the benefit of modelling as key factor to the study of complexity and modern science. Since many scholars frequently adopt instrument from one cultural background to another, they also offer proof on the issue of validity and reliability. The present paper aimed at validating a mathematical modelling test for secondary prospective mathematics teachers.

Methodology: We utilized a survey approach to examine the factor structure of mathematical modelling test for 202 secondary prospective mathematics teachers, selected by cluster random sampling. Mathematical modeling test was adapted to measure the desired constructs. More importantly, we used exploratory factor analysis (EFA), confirmatory factor analysis (CFA) using AMOS 18 and Rasch measurement model with Winstep version 3.73 to analyze the data.

Findings: The EFA and CFA technique verified that a mathematical modelling test was acceptable for Indonesian prospective mathematics teachers. In addition, Rasch analysis also confirmed that all items fit the criteria well and implied that all items are valid in measuring student mathematical modelling competency. This finding concludes that the mathematical modelling test of Indonesian prospective mathematics teachers have an eight-dimension structure.

Contributions: This present research contributes towards psychometric measure on the reliability and validity of a mathematical modelling test in mathematics education programs.

Keywords: Confirmatory factor analysis, mathematical modelling competency, Rasch measurement model.

SCRIPTS ON LINGUISTIC LANDSCAPES: A MARKER OF HYBRID IDENTITY IN URBAN AREAS OF PAKISTAN
Authors: Atta Aqsa 
Published: June 2021

Background and Purpose: Scripts have strong relationship with religion, culture, and identity. This research was conducted to analyze how choice of different language scripts indicates identity crisis by observing placement, size, and preference of one code over the other. Furthermore, it also demonstrates the existence of plurilingual practices on linguistic landscapes.

Methodology: The relationship of scripts with culture and religion was analyzed by following the theoretical framework of semiotics given by Scollon and Scollon (2003) and Huebner (2006). Data was collected through photographs of linguistic landscapes and passersby interviews. Altogether, a corpus of 1064 photographs was collected from three cities in Pakistan (i.e Rawalpindi, Islamabad & Wah Cantt) and 10 passersby were interviewed.

Findings: Data analysis reveals some distinctive linguistic modifications in shop signs and billboards; including deviation in spellings, transliteration, linguistic hybridity, vocabulary, visual representation of language, lack of knowledge of Urdu vocabulary, acceptance of English vocabulary as part of Urdu language and use of sub-standard English vocabulary.

Contribution: The research concludes that erroneous use of language and transliteration practices cause hybrid hybridity. Moreover, considering Urdu alternatives as an oddity, along with inability to retrieve Urdu vocabulary are major challenges for policy makers to promote and implement Urdu language policies.

Keywords: Linguistic landscape, plurilingualism, script and identity, transliteration, translanguaging, linguistic hybridity.

Published: June 2021

Background/Purpose: This study is an attempt to investigate the effect of strategic planning and unpressured within-task planning on Iranian EFL learners’ oral performance.

Methodology: Following a quasi-experimental research design, 60 intermediate EFL Iranian learners were recruited as the participants of the study and they were assigned into two groups of 30. In group one, the participants were asked to perform the task under unpressured online planning condition. In group two, the learners were asked to do the task under strategic planning condition. The pre and post-tests included story-telling narratives tasks followed with a 15-minute silent movie under two planning conditions for the two groups.

Findings: The results of data analysis showed that pre-task strategic planning and within-task planning (online planning) had a positive effect on learners’ oral production; hence, planning time provided opportunity for learners to be able to produce more fluent, accurate, and complex language than no-planners. The results indicated that the participants in the strategic planning group (STPG) significantly outperformed the participants in unpressured within-task-planning (UWPG), leading us to claim that strategic planning was more effective than unpressured within-task planning in improving oral production.

Contributions: This study has numerous benefits for language teachers and specialists in content production. Teachers should incorporate strategic planning in their regular teaching programs to encourage learners to balance their level of speech. Moreover, providing learners with the ability to plan the success of a task allows them to create a more fluent and nuanced language.

Keywords: Accuracy, complexity, fluency, strategic planning, unpressured within-task planning.

Abstract
Nitrate may reduce the ruminal methane emission by competing methanogenesis to achieve more hydrogen. For this purpose, twenty Holstein lactating cows were examined using a 2×2 factorial design in 4 groups for 60 days with two forage levels (40% and 60%) and supplemental nitrate 0% (F40 and F60) and 3.5% (F40N and F60N) of diet dry matter (DM). Then, the effect of nitrate and forage levels on cow performance, ruminal fermentation, methane emission, and metabolic hydrogen sink were evaluated. The nitrate supplementation did not significantly affect milk yield and ECM/DMI, while milk urea nitrogen was increased. Lowest quantity of milk vitamins (A and E) was observed in nitrate groups. The nitrate supplementation increased c9-C18:1, unsaturated fatty acids, and n-6/n-3 contents of the milk. Blood parameters were affected by nitrate supplementation. Blood met-Hb concentration was increased, while blood glucose was decreased in nitrate groups. High forage and nitrate fed animals (F60N) had higher ruminal acetate and lower propionate concentration, and higher acetate+butyrate to propionate ratio than other groups. Nitrite and NH3-N concentrations were higher in the rumen of nitrate fed animals. Nitrate supplementation inhibited gas volume and methane emission without affecting volatile fatty acids at 12 and 24 h of incubation. The H2 balance, H2 production and consumption, and recovery percentage were significantly lower in F60N group. In conclusion, nitrate supplementation can be employed as an alternative strategy for improving ruminal fermentation, milk quality and methane inhibition.

Published: June 2021

Abstract
This study evaluated the effect of addition of Brachystegia eurycoma flour (BEF), a natural source of hydrocolloids, on the physicochemical properties of whole millet flour (WMF) and the sensory attributes of its gluten-free bread. BEF and sodium carboxylmethyl cellulose (a reference hydrocolloid) were added to WMF at 1.5 and 3% proportions, and breads were baked from the blends. Wheat flour (100%CWF) bread served as the control. Amylose level decreased significantly (p < 0.05), while water absorption capacity, peak and final viscosities of the blends increased with increasing proportion of BEF. The 100%CWF bread had better sensory qualities than WMF-BEF breads. Hence, BEF improved the physicochemical properties of WMF-BEF blend, but did not alter the sensory qualities of its gluten-free bread.

Published: June 2021

Abstract
The study investigates rheological properties of dough and baking process made from flour obtained by milling grains from ancient varieties of wheat (einkorn, emmer and spelt), compared to common wheat flour dough (Arkadia variety). The findings show that einkorn flour dough and emmer flour dough present poor tolerance to mechanical processing and prolonged fermentation. These types of dough should be mixed through relatively short, and fermentation time should not exceed 80 minutes for einkorn dough and 45 minutes in the case of emmer dough. In the case of spelt flour dough, the optimum duration of mechanical processing and fermentation amounted to 10 minutes and 60 minutes, respectively. In terms of technological and baking parameters, spelt flour was most similar to the flour obtained by milling conventional wheat, and the superiority of the former was in fact identified in the case of selected factors. A one-stage method was used in the baking process and the bread was then subjected to organoleptic and physicochemical assessments and to texture profile analysis (TPA). Measurements were also performed to determine the indicators reflecting the quality of the baking processes, including dough yield, baking loss and bread yield. The physical parameters of the bread produced were significantly related to the wheat variety. The loaves made from einkorn and spelt flour were of good quality, comparable to the bread made from the conventional wheat, while their baking quality indicators were satisfying. Bread dough made from emmer flour did not meet the required parameters mainly related to the organoleptic assessment and selected physical properties of the bread crumb. However, the one-stage production method should not be applied to doughs made from emmer flour. Given the specific characteristics of the breads produced from the ancient wheat varieties, including their pleasant taste and aroma, as well as attractive colour in the case of einkorn bread, these baked products may be an interesting addition to the assortment of breads on offer from bakeries, restaurants and agritourist farms.

Abstract
Potatoes are considered very important staple and antioxidant-rich tubers in human diet. The present study evaluated the bioactive, antioxidant, antidiabetic and inhibition of lipid peroxidation properties of cooked and uncooked Irish potatoes. The samples were subjected to total phenolic (TPC), total antioxidant capacity (TAC), total flavonoids (TFC), ascorbic acid (AsA) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity analyses using spectrophotometric method. Also Fe2+-induced lipid peroxidation, α-glucosidase and α-amylase inhibition were assayed. The results revealed that there is no significant (p < 0.05) difference in TPC and TAC of the potatoes samples but there was a significant (p < 0.05) enhancement in TFC and reduction in AsA of the cooked potatoes. There is also dose-dependent inhibition in DPPH and α-glucosidase and α-amylase enzymes. The IC50 revealed that cooked sample has significant higher (p < 0.05) inhibition in the enzymes assay. The lipid peroxidation was also reduced upon incubation with Irish potato samples but higher inhibition was exhibited by the cooked potato. In conclusion, this study has shown that Irish potato can be a good functional food in the management of diseases.

Published: June 2021

Abstract
Waste recycling is beneficial not only for the environment but also for the economy and the society at large. Corn stalks, the most abundant crop waste, are processed with oven drying, steaming, complex enzymatic hydrolysis (cellulase, xylanase, β-glucanase and pectinase), and fermentation (by Candida utilis and Pachysolen tannophilus), were analyzed via X-ray diffraction, Scanning Electron Microscopy (SEM) and Infrared Spectroscopy (IR). The results indicated that thermophilic digestion destroyed glycosidic bonds and fibrous crystal have a significant effect on the degradation of the corn stalks, while complex enzyme hydrolysis only slightly degraded fibrous crystal. Fermentation did not significantly reduce fibrous crystal. Therefore, our research suggested that thermophilic digestion is the appropriate way to increase the saccharification rate and feed yield of corn stalks.

Authors: Figiel-Kroczyńska Monika , Ochmian Ireneusz 
Published: June 2021

Abstract
Mini kiwi fruits are tasty and contain valuable nutrients - vitamin, micro end macroelements and polyphenols. The tested cultivars (Sientiabrskaja, Geneva, Issai, Ken’s Red) belong to two species of Actinidia (A. arguta and A. kolomikta), which tolerate well the conditions of a temperate climate with negative temperatures in winter. The effect of postharvest shock cooling on fruit quality was investigated after 6 weeks of storage in CA and then after 5 days of shelf life. Shock cooling of fruit after harvest reduced adverse changes in fruit quality after storage in CA cold storage and shelf life. They were firmer, more puncture resistant, and retained more L-ascorbic acid and polyphenols. After 6 weeks of cold storage in CA, eight types of fungi and molds were found that caused the mycotoxins patulin, deoxynivalenol, and zearalenone were found in the fruit of all cultivars. Fruits of the Ken’s Red cultivar were the most firm and puncture resistant, the darkest, and contained the most anthocyanins and the least L-ascorbic acid. In contrast, fruits of the cultivar Sientaibrskaja were the least suitable for storage and transport.

Published: June 2021

Abstract
Spontaneous bacterial peritonitis (SBP) is a common complication in patients with liver cirrhosis, with an increased risk of mortality. For this reason, a diagnostic paracentesis should be performed in all patients with ascites and clinical features with high diagnostic suspicion. Although literature data abound in identifying new diagnostic markers in serum or ascites, they have not yet been validated. The final diagnosis requires the analysis of ascites and the presence of > 250 mm3 neutrophil polymorphonuclear (PMN) in ascites. If previous data showed that the most common microorganisms identified were represented by gram-negative bacteria, we are currently facing an increase in gram-positive bacteria and multidrug-resistant bacteria. Although prompt and effective treatment is required to prevent outcomes, this becomes challenging as first-line therapies may become ineffective leading to worsening prognosis and increased in-hospital mortality. In this paper we will make a brief review of existing data on the diagnosis and treatment of SBP.
