The Effects of Non-Digital Game-Based Learning and Cognitive Level of Questions on Isometric Transformations
Authors: Hamden Hamid Shamsurya , Zulkiply Norehan , Mohamad Fitri Suraya 
Published: February 2022

Abstract: The present study examined the effects of the non-digital game-based instructional method and the cognitive level of questions in determining students’ achievement in mathematics, particularly in Isometric Transformation. The study used a quasi-experimental design and involved 116 participants (i.e., form two students) from two local secondary schools in Kuching. The participants were divided into control and experimental groups – the control group learned the Isometric Transformation topic via conventional learning, while the experimental group used non-digital game-based learning (NDGBL). The results showed that participants who learned using the NDGBL scored better in the Isometric Transformation test than those who learned the topic using the conventional instructional method. The present findings also showed that participants’ achievement of Isometric Transformation differed significantly between cognitive levels of questions. In particular, participants’ achievements were recorded better for lower-level cognitive questions than higher-level cognitive questions. However, there was no significant interaction effect between the instructional method and the cognitive levels of questions on participants’ achievement in the topic learned. The study provided empirical evidence on the role of NDGBL in learning Isometric Transformation, in that it should be considered as an alternative approach for learning Isometric Transformation and Mathematics in general, with an effective integration into the secondary mathematics curriculum.

Mathematical Readiness of Freshmen Engineering Students (K-12 2020 Graduates) in Eastern Visayas in the Philippines
Authors: Wenceslao Perante 
Published: February 2022

Abstract: This study assessed the mathematical and analytical readiness of the incoming first-year college engineering students (K-12 2020 graduates) in Eastern Visayas in the Philippines. First-year engineering students (n=177) participated in the College Math Readiness Test (CMRT), a questionnaire on mathematics subjects that covered Precalculus, Analytical Geometry, Series and Mathematical Induction, Trigonometry, and Basic Calculus: Limits and Continuity, Derivatives, and Integration. The findings indicate that 43% of the respondents were mathematically-college-ready (MCR) and 57% were not-mathematically-college-ready (NMCR). Regarding the NMCR, 39% fared fairly and 18% fared poorly in the CMRT. This suggests that remedial support for mathematics for this group may be required for them to be college-ready for an engineering course. The respondents had the lowest correct mean score for the Integration subjects: Evaluating Differential Equations (15%), Evaluating Definite Integrals (16%), and Solving Area Between Curves (19%). The results of the ranking of the Senior High Schools (SHS) showed that 13 SHS with at least 2 takers and 24 SHS with single takers need to improve their quality of teaching to enhance the mathematical competence of their graduates. The findings of this study were used to identify remediation areas and recommendations to improve the students' college mathematical and analytical readiness.

Internationalisation of Curriculum Delivery: Complexities of English as an Instructional Language in a non-English Culture
Authors: Mohd Faiz Nur Sofurah , Mohamed Maziana 
Published: February 2022

Abstract: English language is the main lingua-franca in higher education worldwide. For that reason, higher education institutions in Malaysia including the Malaysian Technical and Vocational University (MTVU, a pseudonym) have been promoting English as the language of instruction. With the existence of international students and voluminous English academic resources, implementing English as the language of instruction is a significant commitment. International students, as well as academic staff in MTVU however, come from various non-western cultures where English is not their native language. This paper focuses on an issue related to the use of English language amongst these groups in learning and teaching processes. Jin’s (1992) theories underlying Cultural Synergy model was used as the underpinning theories of the study. Data collected were from focus group and semi–structured in-depth interviews which were conducted with eleven international students and nine academic staff in MTVU. Through interpretive thematic analysis, findings highlighted that limited English proficiency is not only an issue solely for international students, but also for academic staff. This paper reveals this unique and complex issue from the perspectives of both students and staff. The paper then further discusses the consequences of these complexities for the learning and teaching environment.

Research of cascade averaging control in hydraulic equilibrium regulation of heating pipe network
Authors: Liu Chunlei , Wang Peiqi , Yang Zhijun , Guo Lijiao , Gao Tian , Wang Chen , Sun Yong 
Published: February 2022

Abstract
The heating pipe network system with such dynamic characteristics as nonlinearity and large time lag may cause hydraulic disorder. To solve this problem, this paper proposes a unit control-based hydraulic equilibrium control strategy, which constructs an equilibrium regulation system for heating pipe networks by optimising the inlet device of each unit and using a novel control theory. By developing a cascade control system to control the return water temperature and the pressure difference between supply and return water of the branches at each unit of the pipe network, we were able to stabilise the pressure and control the temperature. Then, we used the averaging control theory to set the parameters of regulation systems between each unit. The research results indicate that, compared to the traditional single-loop negative-feedback return water temperature control system, the cascade averaging controller has a better control effect than the single-loop PID controller. This is because it has a smaller overshoot and can cope with system interference factors quickly. Therefore, the temperature of return water between each unit can be coordinated and fluctuation is within a smaller range. This effectively eliminates the influence of static and dynamic hydraulic disorder on entire system stability.

Authors: Pachava Srinivasa Rao , Goel Masoom 
Published: February 2022

Abstract

Study aim: Popliteus is majorly associated with posterior knee pain; however, this muscle can also have an impact on anterior knee pain. The purpose of this study was to determine the effect of soft tissue manipulation of popliteus muscle on non-traumatic anterior knee pain in athletes; as the relationship between popliteus and Quadriceps muscle has not been studied/explored much.

Materials and methods: In this experimental study, 15 subjects presenting with non-traumatic anterior knee pain were selected. Quadriceps muscle activity, torque production and knee pain were assessed. Followed by a single session of popliteus manipulation all the above parameters were re-assessed immediately and at 24 hours after intervention.

Results: Significant reduction in pain (P < 0.005) at 24 hours was observed. There was a significant increase in muscle activity of Vastus Medialis (P < 0.05) and Vastus Lateralis (P < 0.005) immediately after the intervention but not after 24 hours. No significant change was found in the activity of Rectus femoris and Peak torque of Quadriceps immediately after the intervention and at 24 hours.

Conclusion: Soft tissue manipulation decreased knee pain and improved muscle activity. Therefore, incorporating popliteus manipulation can be effective in treatment of anterior knee pain.
Triple-layer remote phosphor structure: A potential packaging configuration to enhance both color quality and lumen efficiency of 6,000–8,500 K WLEDs
Authors: Le Phan Xuan , Ho Sang Dang , Quoc Anh Nguyen Doan , Lee Hsiao-Yi 
Published: February 2022

Abstract
To achieve further enhancement in the lighting quality of white light-emitting diodes (WLEDs), this study proposed a packaging structure with three different phosphor layers, called triple-layer remote phosphor structure. This structure can provide an overall control over the light color distribution of WLEDs. The yellow-green-emitting CaAl2O4:Mn2+ phosphor and red-emitting CaMoO4:Eu3+ phosphor are used along with the original yellow-emitting YAG:Ce3+ phosphor to fabricate the triple-layer structure. The concentration of yellow-emitting YAG:Ce3+ phosphor is required to be decreased as the concentrations of other phosphors increase to keep the predetermined correlated color temperatures. The color rendering index (CRI) and the color quality scale (CQS) are measured to reach a thorough color quality assessment for WLEDs. The color management can be achieved by adjusting the concentration of red-emitting CaMoO4:Eu3+ phosphor to enhance the red emission. In addition, adjustment of the concentration of yellow-green-emitting CaAl2O4:Mn2+ phosphor can result in higher luminous efficiency owing to its control over the green light components. Higher CRI is observed when CaMoO4:Eu3+ concentration increases, while an increase in CaAl2O4:Mn2+ phosphor leads to much lower CRI. The CQS – on the other hand – is remarkably high when the CaMoO4:Eu3+ concentration range is about 10wt%–14wt%, regardless of the proportion of the CaAl2O4:Mn2+ phosphor. Furthermore, 40% enhancement in luminous efficiency is also achieved since light scattering is minimized by the boosted green-light emission spectra. Manufacturers can take these findings as reference to fabricate high-quality WLED lights that fulfill all their requirements.

Authors: Szombara Stanisław 
Published: February 2022

Abstract
The paper presents the review of mapping techniques applied in research using mental maps. The review covers both evaluative and structural mapping. The choice of a method is influenced by the level of freedom given to the respondents while creating sketch maps. It is also highly affected by the area of a given region, scale used in the research and limitations of mapping techniques in GIS software. For large scale maps created in GIS software, it is possible to use quantitative methods, i.e. proportional symbol maps or quantitative signature symbols. Using multiple complementary mapping techniques allows to draw the most comprehensive conclusions in the analyses of perception of a given space in the society.
Liberalización de los servicios de alta velocidad ferroviaria en España: el proceso de apertura del mercado a la competencia
Authors: Lerida-Navarro Carlos , Nombela Gustavo 
Published: February 2022

El objetivo de este trabajo es analizar la apertura a la competencia en España de los trenes de pasajeros de alta velocidad. Formalmente, la liberalización ferroviaria culminó en 2020 con la firma de contratos-marco con tres operadores (Renfe y dos nuevos entrantes), si bien la pandemia sanitaria ha retrasado todas las fechas planeadas y ha introducido mucha incertidumbre sobre cómo evolucionará este mercado. Tras realizar un análisis completo de la movilidad en los corredores licitados, el principal reto que identificamos es que la nueva oferta prevista parece muy ambiciosa, incluso para la demanda anterior al COVID-19. Si se añaden además los probables cambios en la movilidad post-pandemia, nuestra principal conclusión es que a medio plazo un equilibrio con tres operadores ferroviarios ofertando alta velocidad en España parece altamente inestable.

Authors: Morina Morina , Sidjabat Oberlin 
Published: February 2022

Plastic wastes which come from municipal solid wastes, have been identi􀂿 ed as the worldwideenvironmental problem in the last decades. Chemical recycling is one of the alternative methods to solvesuch problem. Inorder to obtai appropriate liquid fuels, polypropylene plastic waste was degraded thermallyand catalytically in the presence of natural zeolite incorporated with chromium (Cr) and nickel (Ni) metals.The reaction was conducted in a 􀂿 xed bed reactor in the temperature range of 400-500°C. The dependenciesof process temperature and effect of catalyst on yield of the fuel fractions were determined and comparedto commercial gasoline fractions. The current study shows that the major product of thermal degradation(pyrolysis) and catalytic degradation is liquid (gasoline) fraction and the highest products obtained attemperature 450°C is approximately 77.84%. The use of chromium and nickel metals on activated naturalzeolite as a bi-functional catalyst enhance the yield of liquid fractions and the acidity of the catalysts. The liquid product obtained in this process was analyzed using GC for its composition. Synthesized catalysts, activated natural zeolite and natural zeolite were characterized by means of nitrogen physisorption (BET), porosity, X-ray diffraction (XRD), and acidity. Based on the obtained results, the catalyst containing 6% of chromium and 4% of nickel on activated natural zeolite is a good catalyst for conversion of polypropylene plastic wastes to liquid (gasoline) fuels. Catalytic conversion using such catalysts may applicable as an alternative method for recycling plastic wastes to more valuable commodities such as fuel oils.

Reservoir characterization analysis has been carried out for identifying lithology and Àuid content on TalangAkarFormation in South Sumatra Basin. Robust method that being used in this study is the simultaneous inversion which uses pre-stack gather and well log data from Puja A and Puja B. Elastic parameters resulted from simultaneous inversion are P Impedance, S Impedance and V / V ratio. Lambda-Rho parameter (lr) and Mu-Rho (mr) derived from P impedance (I ) and S impedance (I ). Lambda-Rho is sensitive to Àuid content while Mu-Rho to lithology. Area of interest in this study is Talang Akar Formation as reservoir which contains gas with Lambda-Rho (lr) between 5-15 (GPa*g/cc) and Mu-Rho (mr) 35-45 (GPa*g/cc). The ratio of P wave (Vp) and S wave (Vs) can be used as an indicator to determine Àuid saturation. Gas saturated rock has value of Vp / Vs lower than the water saturated rock. In this study, the ratio of Vp / Vs is 1.5-1.7 for gas saturated rock

Background: Benign Prostatic Hyperplasia (BPH) is the most common urological cause of urinary obstruction, affecting men above 50 years of age. Medical therapy used for managing BPH includes various medical regimes, including 5-alpha reductase inhibitors (5ARI), namely Dutasteride and more. The study aimed to evaluate the efficacy of four weeks' prior treatment with dutasteride on per-operative blood loss in patients of BPH undergoing transurethral resection of the prostate.
Methodology: A prospective observational study was conducted from January to December 2019 at the Kidney Centre, Karachi, Pakistan. A total of 64 patients were included and divided into two groups. Group A patients were those who had been taking dutasteride (0.5 mg/day) for four weeks or more before surgery, and group B patients were not taking dutasteride drug before surgery. All patients underwent standard TURP, and the intra-operative blood loss was calculated. The collected data was analyzed using SPSS version 22.0.
Results: In our study, there was a significantly less hemoglobin drop (1.2 gm vs. 2.2 gm) during prostate surgery in patients using dutasteride than those who were not using dutasteride.
Conclusion: This study has revealed that the use of dutasteride four weeks before surgery significantly reduces intra-operative bleeding.

Published: February 2022

Background: Foodborne illness is a global health problem, and Salmonella is one of the leading bacterial pathogens to cause salmonellosis and typhoid fever worldwide. These infections remain an obstinate risk to human and animal health despite substantial innovations and cleanliness practices. The high incidence of these infections is resulting not only from infected eggs and chicken but also from different food commodities. This research was designed in the direction of the certainties mentioned above and the high occurrence rate of extensively drug-resistant (XDR) infections in Pakistan.
Methodology: The study focused on the isolation and identification of Salmonella species from food and water samples collected from different regions of Karachi, Pakistan. The standard protocol of enrichment, culturing, and biochemical confirmation from Biological Analytical Manual (BAM) was used to characterize Salmonella's phenotypic isolation and characterization. These isolates were then subjected to Polymerase chain reaction (PCR) and resolved on 1.5% agarose via electrophoresis.
Results: From the total of 1010 samples, 10 genotypically confirmed Salmonella isolates were obtained by detecting the invA gene by using PCR. Food items of different kinds exhibited 80% of the total positive isolates, while 20% is from the water sample.
Conclusion: The study exhibited the highest prevalence of Salmonella in chicken meat, which may indicate insufficient hygiene and sanitation practices during slaughtering and the supply chain. Incidence of Salmonella was also found in water and spices, signifying the improper sanitary systems and unhygienic handling of food items in many localities of the city, affecting human health.
