THE CORRELATION BETWEEN STUDENTS’ LEARNING STYLE AND ENGLISH ACHIEVEMENT AT SMP MUHAMMADIYAH 1 GRESIK
Authors: Maulidiyah Nur Aza
Published: June 2021

The students have their own model for learning language to reach the goal of learning. Learning style is the way of the students to decide the effective and efficient way to sense, remember, process, and save what they have tried to learn. However, the students of junior high school, especially at eighth grade, they have their own learning style to learn the language, but they have not known yet which learning style that can help them achieve English achievement. Meanwhile, there are four kinds of learning style. Those are converger, concrete, conformist, and communicative learners. This quantitative study wants to investigate whether there is correlation between students’ learning style and English achievement. The researcher gave the questionnaire which was adopted from Willing (1988) to the students to find the students’ learning style. 25 students of Muhammadiyah junior high 1 Gresik grade 8A were given the questionnaire. Then, the researcher gave writing test to 17 students who have converger and concrete learning style to know their English achievement. The result of this study showed the different result with the previous study. The previous study showed that converger and concrete could give impact on students’ academic achievement. This study showed that there was no significant correlation between converger learning style and English achievement. On the other hands, the result of concrete learning style has the similar result with the previous study which showed significant correlation between concrete learning style and English achievement since the subject of the study was high school students

Published: June 2021

Role play is a method of acting out particular ways of behaving or pretending to be other people who deal with new situations.  Role play is very important in teaching speaking because it gives students an opportunity to practice communicating in different social contexts and in different social roles. The purpose of this study is to find out the significant effect on students fluency in speaking skills taught by using Role Play for students in Junior High School. The researcher used an experimental design in which there are two classes; one of the experiment group and the control group that each has 20 students. The data is collected through quantitative methods. The quantitative data is obtained from the result of the pre-test and post-test students speaking skills. Before implement Role Play, students had to take pre-test to identify their speaking ability. One group practice a dialogue in pair use Role Play strategy about greeting, leave taking, thanking and apologizing expressions. Other group was asked to practice a dialogue used drilling strategy. Both groups were tested for their oral production and competence. After the presentation, the post-test was used to find out whether there was a significant effect using Role Play in speaking ability. The implementation of Role Play and Drilling showed that students who are though used Role Play in teaching speaking can improve their speaking skill especially in fluency.

Published: June 2021

In the intense mucilage formation observed in the Sea of Marmara in 2021, Phaeocystis pouchetii (Prymnesiophyceae) together with Skeletonema costatum, Cylindrotheca closterium, Thalassiosira rotula (Bacillariophyceae), and Gonyaulax fragilis (Dinophyceae) were detected in the foamy mucilage in the surface layer, and Chrysoreinhardia giraudii and Nematochrysopsis marina (Chrysophyceae), which are known to produce filamentous mucilage in benthic habitat. In addition, with the contribution of these groups, a higher cell abundance (2.1×107 cells/L) and chlorophyll-a value (15.9 µg/L) was reached than the mucilage event experienced in previous years. In the microscopic observations, typical dominant genera of the Sea of Marmara such as Protoperidinium and Tripos were observed very little in terms of species composition, and the fact that three previously unobserved species became dominant and the Cyanophyceae group was represented by different species indicated that phytoplankton composition changed in the mucilage formation in this period. The changing species composition with these 3 species that are known to make mucilage and which are new records for the Sea of Marmara point to the transportation by ship ballast waters or the inflow of brackish water with heavy rains. It is recommended to take the necessary measures to control domestic and industrial wastes and terrestrial inputs, which cause these species to reach numerical abundance and form mucilage, to carry out fisheries in a controlled manner, and to prevent the discharge of ship ballast waters and bilge waters.

Published: June 2021

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

Published: June 2021

Water stress is one of the foremost categories of stress damaging plants’ overall growth and development. The aim of the present study was to explore and demonstrate stress-induced drought to calibrate changes in stress parameters of two banana plant varieties viz. Grand naine (G9)  and Nalla bontha were cultured in Murashige and Skoog medium (MS) media supplemented with stress inducers -Poly ethylene glycol (PEG)  and sorbitol. The different concentrations of inducers were used to induce drought stress in two varieties of banana with contrasting characters for drought condition. The study indicated that PEG contrived mild to moderate osmotic stress and so does the alditol i.e. sorbitol on in vitro banana plants.  The different concentrations of PEG and sorbitol produced significant effects on various parameters. The maximum decrease in shoot length was prominent in G9(52%) as compared to Nalla bontha (11%). When treated with 3% w/v sorbitol, even average root length showed the same level of damage with G9(59%) while in case of Nalla bontha there  was  a 17% decrease. The banana plantlet produced in vitro was estimated at one and two weeks after inoculation, respectively. Proline content tended to increase as the concentration of osmotic inducers increased (-44 % in G9 at 3% w/v sorbitol), whereas RWC (8.9% in G9 at 3% w/v Peg) showed an opposite effect. It was concluded that quantitative and qualitative changes in physiological (shoot and root length) and biochemical (Proline and relative water content, RWC) parameters played an important role in plants under drought stress conditions. This pattern varied from species to species. This work has been attempted for the first time in banana, especially Grand naine varieties with contrasting characters under induced drought stress.

Published: June 2021

Soil carbon is one of the most affected variables to land-use change in tropics. The soil carbon flux plays a major role in regulating microbial activities and nutrient distribution in soil. This study aimed to evaluate the soil carbon stock in various land uses at different depths in the hilly terrain of Mizoram, Northeast India. Soil samples at 0-10 cm, 10-20 cm and 20-30 cm soil depths were collected from Rubber plantation (RP), Oil palm plantation (OPP), Teak plantation (TP), Bamboo Forest (BF), 5 years fallow (5YF), 10 years fallow (10YF), Tephrosia candida plantation (TCP), Horticulture garden (HORT), Homegarden (HG) and Natural forest (NF). Soil carbon stock varied significantly (p <0.05) across the land uses and depths. The soil under Tephrosia candida stand had significantly (p <0.05) higher values of C stock (73.66 Mg ha-1) which may be due to high biomass, dense vegetative cover and high C in root exudates. The minimum C stock estimated in Horticulture garden (43.28 Mg ha-1) is probably due to reduced soil organic matter. Soil carbon stock in Homegarden, Teak plantation, Bamboo forest and Rubber plantation ranged from 46.82 Mg ha-1 to 59.34 Mg ha-1 whereas 5 years and 10 years fallow land, Natural forest and Oil palm plantation ranged from 61.35 Mg ha-1 to 73.35 Mg ha-1. The study indicated that the land use change in the mountainous region significantly affected the carbon stock in the soil. A proper land use management strategies to increase the soil organic matter is recommended to enhance the carbon stock in this region.

Authors: Patil Archana H. , Jagdale Sandesh
Published: June 2021

Pollinators are rewarding for many wild and agricultural crop plants. The experiments were conducted in the agricultural field of Karad tehsil, Maharashtra, India. The present study concentrated on the diversity and species richness of nocturnal insect pollinators on Ridge gourd Luffa acutangula belonging to the family Cucurbitaceae. The Ridge gourd plant is monoecious with a bunch of male flowers and solitary female flower. Anthesis happened in late evening hours (17.00-19.00) and flowers remained for 13 to 14 hours. A total of 830 insect pollinators were sampled from June 2020 to November 2020. Altogether 17 species of insect pollinators belonging to 7 families under 6 orders were recorded. Among the total number of species, the Lepidoptera was the dominant order comprising  11 species belonging to the single family Crambidae followed by Blattodea comprising 2 species belonging to 2 families Ectobiidae and Blattidae. Hymenoptera comprised 1 species belonging to family Formicidae, followed by order Orthoptera comprising 1 species belonging to family Gryllidae, order Diptera  comprising  1 species belonging to the family Culicidae, followed by the order  Coleoptera  comprising 1  species belonging to the family Chrysomelidae. The Diaphnia hyalinata belonging to family Crambidae of  the order Lepidoptera was the most dominant species and was followed by Chabula acamasalis. The nocturnal species imparted pollination services to agricultural crops. The study also observed fundamental mechanisms of plant and nocturnal insect pollinator interaction as well as floral scent and visual signals. The study can be baseline data for conserving and managing the best pollinators for increasing the yield of Ridge gourd.

Authors: S Madhusudhan , Jalali S.K. , G Sibi
Published: June 2021

The cotton bollworm Helicoverpa armigera occurs as a major pest in many economically important crops, including cotton, pigeon pea, chickpea, pea, cowpea, sunflower, tomato, sorghum, pearl millet and other crops. Intestinal microorganisms play important role in the degradation of diet components of insects. In order to know the role of gut bacteria in insecticide resistance five   insecticides Chlorpyriphos (20% EC), Cypermethrin (25% EC), Malathion (50% EC), Quinalphos (25% EC), Triazophos (40% EC), were selected for the insecticide degradation studies. All the bacterial isolates from the gut of lab and field populations of H. armigera were identified using 16S rRNA gene-based identification and tested for their growth on minimal salt medium (MSM) along with the selected insecticides. A total of 11 bacterial isolates were tested and among them, isolate CL4 (Rhodococcus sp.) was found to grow on minimal salt medium (MSM) and with chlorpyriphos and isolate CL2 (Enterococcus casseliflavus) was able to grow in MSM with chloropyriphos (C22H19Cl2NO3) and malathion (C10H19O6PS2) and no growth was seen in MSM without insecticide (control).  Gas Chromatography analysis of the positive bacterial isolate cultures in MSM showed that the isolate CL4 (Rhodococcus sp.) was able to utilize 43.9% of chlorpyriphos and isolate CL2 (E.casseliflavus) was able to utilize 26% of chlorpyriphos and 57.1% of malathion in MSM broth cultures with comparison with the respective control cultures. Findings of the current work suggested that gut bacteria in the field populations of H. armigera plays a role in insecticide resistance
Orientation cues and mechanisms used during avian navigation: A review
Authors: Tyagi Tushar , Bhardwaj Sanjay Kumar
Published: June 2021

The navigational systems of different animal species are by a wide margin less notable as compared to birds. Humans have been interested in how migratory birds discover their way more than thousands of miles for quite a long time. This review summarizes the cues and compass mechanisms applied in orientation and navigation by non-migrants, diurnal and nocturnal migrants. The magnetic compass, landmarks, olfactory, and memory of spatial cues en route were utilized in homing and migration. The equivalent is valid for the sun compass despite the fact that its job during migration might be undeniably less significant than commonly presumed. Stellar compass and celestial rotation, as a result of their nighttime accessibility, appear to influence the direction of nighttime migrants during the course of migration. The celestial cues go through notable changes because of the latitude shift during bird migration. Sunset cues alter their location with seasons and latitudes. The recognizable stars lose height and lastly vanish underneath the horizon, whereas new stars show up. These new ones must be calibrated. As celestial rotation not imparting a reference, it is not unexpected that the magnetic compass turns into the main cue that controls the directional importance of stars and sunset cues. Field studies have revealed that, in certain species, a considerable extent of individuals get back to similar breeding, overwintering, and stopover areas in progressive years. This review proposes that migratory birds have advanced uncommon cognitive capacities that empower them to achieve these accomplishments.
Fusarium pallidoroseum: A potential entomopathogenic agent for the biological management of Aphis gossypii
Authors: Srivastava Ritu , Shukla Amritesh Chandra
Published: June 2021

With rising need of switching over to sustainable agricultural practices, utilization of entomopathogenic fungi (EPF) as biocontrol agents, provides better substitute against chemical pesticides- having several side-effects. Therefore, an attempt have been made to explore the potential EPF fungi that could be incorporated into IPM practices for control of Helicoverpa armigera Hubner and Aphis gossypii Glover. Regarding this, an entomopathogenic fungus, Fusarium pallidoroseum (Cooke) Sacc, was isolated from natural population of H. armigera infesting chickpea (Cicer arietinum L.) and explored efficacy under in-vitro & field conditions. The findings of present investigation shows efficacy of F. pallidoroseum as potential biocontrol agent against okra aphid (A. gossypii), as it inflicted initial mortality of 43.33% nymphs on 2nd day and lead to complete annihilation (93.33%) of nymph population on 8th day of spore suspension application at 1x1010 spores/mL concentration. The observations against adult okra aphid clearly demonstrated that spraying of 1 x 1010 spores/mL of F. pallidoroseum resulted 66.67% mortality after 8th days of spraying. Increased mortality was recorded with increase in spore suspension concentrations. The LC50 & LC90 value for F. pallidoroseum against nymphs of A. gossypii was recorded 3.79 x 105 and 2.74 x 108, respectively. The findings were used to develop  formulations (1 × 104  to 1 × 1010 spore suspension/mL conc),  and tested  at field-level. The results showed that formulation at 1 x 1010 spores/mL conc was most effective against A. gossypii, recorded 93.33% mortality of nymphs & 66.67% mortality of adults; could be used under IPM practices.

Abstract Background: Ficus exasperata Vahl. (Moraceae) is widely used in African traditional medicine for the treatment of various diseases. The present study is undertaken to assess the anti-oedematous and antinociceptive activities of the stem bark aqueous extract of Ficus exasperata in mice and rats. Methods: The anti-oedematous activity was investigated following carrageenan or histamine-induced rat paw oedema models. Antinociceptive activity was evaluated using acetic acid induced writhing test (1 %, 10 ml/kg), capsaicin-induced neurogenic pain (32 µg/mL, 30 µL) and formalin-induced test (1%, 20 µL). Extract was administrated orally at 37.5, 75 and 150 mg/kg. Results: Pre-treatment of rats with Ficus exasperata stem bark aqueous extract exhibited significant inhibition of paw oedema during all the phases of both carrageenan and histamine induced edema in rat. The maximum inhibition percentages were 94.75 % (3 h) and 30.64 % after one hour at the dose of 37.5 mg/kg, respectively, in carrageenan or histamine models. Antinociceptive activity showed that aqueous extract reduced signiﬁcantly (p < 0.001) the pain induced by acetic acid with an inhibition percentage of 70.8% (150 mg/kg). In the formalin-induced test, the extract also reduced signiﬁcantly (p < 0.001) licking time during neurogenic phase and inﬂammatory phase with inhibition percentages of 44.75% and 52.78% respectively at the dose of 75 and 150 mg/kg. In addition, aqueous extract of F. exasperata reduced signiﬁcantly (p < 0.001) neurogenic pain induced by capsaïcin by 71.28 % at the highest dose (150 mg/kg). Conclusion: This finding suggests that the stem bark aqueous extract of Ficus exasperata possess potent anti-oedematous and antinociceptive activities. Keywords: Aqueous extract; anti-oedematous; antinociceptive; Ficus exasperata.
A Study On Assessment Of Stress And Its Management In Hospital Employess
Authors: Amin Noorul , Ahmad Muzamil
Published: June 2021

Stress refers to the strain from the conflict between our external environment and us, leading to emotional and physical pressure. In our fast paced world, it is impossible to live without stress, whether you are a student or a working adult. There is both positive and negative stress, depending on each individual’s unique perception of the tension between the two forces. Stress bears deliberating effects on both the employees and the employer. As per Dr H seyles, Stress is defined as “a state of psychological and physiological imbalance resulting from the disparity between situational demand and the individual’s ability and motivation to meet those needs”. The word stress has its origin in the Latin word string ere to draw tight. In the 17thcentury the word was used to describe affliction and hardship. The meaning of the word later included the concepts of pressure, strain or force. Today the description of stress includes an outside stimulus and the person’s response to it. Several studies have focused on the possible relation between stress, illness and different ways people respond to it. These studies distinguish the various aspects of stress which a person may face in life, e.g. stress at home, in personal life or at work. This review focuses on stress at work, with particular emphasis to the nursing profession, in an attempt to explore possible management strategies that may decrease it (Golubic etal., 2009, Lu et al. 2009).

BackgroundPeople with disabilities (PwD) have been facing multiple health, social, and economic disparities during the COVID-19 pandemic, stemming from structural disparities experienced for long time. This paper aims to present the PREparation, RESponse and SySTemic transformation (PRE-RE-SyST): a model for a disability-inclusive pandemic responses and systematic disparities reduction.MethodsScoping review with a thematic analysis was conducted on the literature published up to mid-September 2020, equating to the initial stages of the COVID-19 pandemic. Seven scientific databases and 3 preprint databases were searched to identify empirical or perspective papers addressing health and socio-economic disparities experienced by PwD as well as reporting actions to address them. Snowballing searches and experts’ consultation were also conducted. Two independent reviewers made eligibility decisions and performed data extractions on any action or recommended action to address disparities. A thematic analysis was then used for the model construction, informed by a systems-thinking approach (i.e., the Iceberg Model).Results:From 1027 unique references, 84 were included in the final analysis. The PRE-RE-SyST model articulates a four-level strategic action to: 1) Respond to prevent or reduce disability disparities during a pandemic crisis; 2) Prepare ahead for pandemic and other crises responses; 3) Design systems and policies for a structural disability-inclusiveness; and 4) Transform society’s cultural assumptions about disability. ‘Simple rules’ and literature-based examples on how these strategies can be deployed are provided.Conclusion:The PRE-RE-SyST model articulates main strategies, ‘simple rules’ and possible means whereby public health authorities, policy-makers, and other stakeholders can address disability disparities in pandemic crises, and beyond. Beyond immediate pandemic responses, disability-inclusiveness is needed to develop everyday equity-oriented policies and practices that can transform societies towards greater resiliency, as a whole, to pandemic and other health and social emergencies.
Determining the absolute sustainability of products with case studies on laundry and food production
Authors: Sherwood James
Published: June 2021

In this work, a new metric called ‘Service-weighted Product Level Absolute Sustainability’ is proposed as a numerical indicator to determine if a product is sustainable. The service offered by a product was found to be crucial to normalize its environmental impact and permit comparisons between products. Service-weighted Product Level Absolute Sustainability is demonstrated here with examples of water use for laundry and food production. The maximum justifiable environmental impact of these products has been calculated based on their performance, i.e., the quantity of clothes washed or nutritional content. Now the environmental impact of products can be rationalized as either sustainable or unsustainable, informing sustainable choices by manufacturers as well as consumers.
“Breathing is the absolute key”: using mixed-methods to understand how a digital mindfulness intervention can improve quality of life for adults with asthma.

Published: June 2021

Introduction: Despite effective pharmacotherapy, patient-reported asthma outcomes such as quality of life remain suboptimal. Digital mindfulness interventions may be helpful for people with asthma by targeting psychological dysfunction such as illness perceptions, anxiety and depression.Methods: In a mixed-methods process evaluation, we examined how ‘Headspace’, a widely-used digital mindfulness intervention, was used in a randomised controlled feasibility trial of adults with asthma from 16 UK GP practices. 94 adults who were allocated to the intervention completed questionnaire measures of anxiety, depression, quality of life and illness perceptions, and 27 were selected to complete in-depth qualitative interviews. Findings were triangulated with ‘back-end’ usage data from the Headspace digital intervention.Results: Interviews explored participant perceptions of mindfulness interventions (and non-pharmacological interventions more broadly), as well as wider psychological factors relevant in asthma, such as anxiety, depression, mindful acceptance and awareness, and psychological inflexibility. The amount that Headspace was used was not associated with the degree of improvement in outcome measures and in general participants perceived the intervention as useful, and reported it was helpful for their wellbeing. They were generally positive about mindfulness interventions, especially digital ones. Conclusions: Digital mindfulness interventions are acceptable for people with asthma and disease-specific content should be used to target illness perceptions that may underlie reduced quality of life for people with asthma.
Bridging Feminist Psychology and Open Science: Feminist Tools and Shared Values Inform Best Practices for Science Reform
Authors: Matsick Jes , Kruk Mary , Oswald Flora , Palmer Lindsay
Published: June 2021

Feminist researchers have long embraced the challenging, dismantling, and reimagining of psychology, though their contributions to transforming psychological science remain largely overlooked in the mainstream open science movement. In this article, we reconcile feminist psychology and open science. We propose that feminist theory can be leveraged to address central questions of the open science movement, and the potential for methodological synergy is promising. We signal the availability of feminist scholarship that can augment aspects of open science discourse. We also review the most compelling strategies for open science that can be harnessed by academic feminist psychologists. Drawing upon best practices in feminist psychology and open science, we address the following: generalizability (what are the contextual boundaries of results?), representation (who is included in research?), reflexivity (how can researchers reflect on who they are?), collaboration (are collaborative goals met within feminist psychology?), and dissemination (how should we give science away?). Throughout each section, we recommend using feminist tools when engaging with open science, and we recommend some open science practices for conducting research with feminist goals.
‘One bearded sage concluded: there’s no motion.’ Pushkin’s ‘philosophical epigram’ and a dispute about hexameter
Authors: Abdullaev E. V.
Published: June 2021

Pushkin’s epigram ‘Motion’ [‘Dvizhenie’] (1825) has fascinated scholars for years. However, all its interpretations relied on its external context — either philosophical or political. The article sets out to interpret ‘Motion’ in the light of the literary and polemic agenda that was on Pushkin’s mind at the time of the poem’s writing. Printed in the fourth issue of Küchelbecker’s Mnemozina for the year 1825, practically right before Pushkin’s ‘To the Sea’ [‘K moryu’], were Küchelbecker’s hexameters entitled ‘A hymn to Bacchus (from Homer)’ [‘Gimn Bakhusu (Iz Gomera)’], with a note of ‘Tsarskoe Selo, 1817.’ This may have seemed to Pushkin a reference to the dispute around hexameter (in the years 1813–1814 and 1817–1820); the episode with an argument between two philosophers was included in the response that S. Uvarov, a proponent of hexameter, wrote to V. Kapnist, who promoted the versification of Russian folk songs as an alternative to hexameter. This allows for the assumption that Pushkin’s epigram was addressed to Küchelbecker, with whom, since their time at the Lyceum, Pushkin had engaged in a dispute about the suitability of hexameter for Russian poetry.
Discord. Essays on folk aesthetics in an era of disappearing time. On the novel The Best Is Still to Come [Vsyo vperedi] by V. Belov
Authors: Chernov A. V.
Published: June 2021

The article discusses V. Belov’s novel The Best Is Still to Come [Vsyo vperedi]. Published in 1986, the novel became a target of numerous scathing reviews, remaining one of the writer’s most controversial books to this day. The article examines the polemic between D. Urnov and A. Malgin published in Voprosy Literatury in 1987. The author goes on to propose the novel’s modern interpretation based on such concepts as I. Shaytanov’s ‘one-time form’ and Z. Bauman’s ‘retrotopia.’ He finds that The Best Is Still to Come is unique from the viewpoint of its genre, and so are Belov’s other works Harmony. Essays on folk aesthetics [Lad. Ocherki narodnoy estetiki] and The Daily Life of Russian North [Povsednevnaya zhizn russkogo Severa]. Analysed are the novel’s chronotope, shifts and disruptions of artistic time, and confusion in the artistic space. The key image of this urban novel by Belov, discord (raz-lad ) is contrasted with the image of harmony, con-cord (lad ) that permeates his writings about the traditional rural lifestyle.

Authors: Noga Marcin , Gorczyca Paweł , Hebda Radosław
Published: June 2021

Research on the effects of the use of the range extender developed for a small commercial electric vehicle was presented in this paper. The range extender has a maximum output power of 2.65 kW. The developed auxiliary power unit consists of a three-phase generator propelled by an industrial low-power spark-ignition engine. The exhaust system was improved using a more efficient muffler. The implemented motorcycle muffler has a three-way catalyst (TWC) integrated inside. The use of the more advanced exhaust system aimed at reducing noise and exhaust emissions of the range extender. The efficient operation of the three-way catalytic converter requires a stoichiometric air-fuel ratio. To enable desired air-fuel ratio a fuel system was modified. In the first stage of research, the effects of improvements of the exhaust system on the range extender noise emissions were quantified. The next step covered the research of the fuel conversion efficiency, the exhaust gas composition, and the efficiency of conversion of the three-way catalyst. A significant decrease of noise and toxic gas emissions and an increase in the fuel conversion efficiency were revealed. The mentioned research was conducted in stationary conditions. After that, in the final part research of the running vehicle with the range extender on was made. The beneficial outcome of these tests enabled the development of a set of rules of the control of the range extender.
Comparative Study of Municipal Solid Waste Fuel and Refuse Derived Fuel in the Gasification Process Using Multi Stage Downdraft Gasifier
Authors: Mujiarto Sigit , Sudarmanta Bambang , Fansuri Hamzah , Saleh Arif Rahman
Published: June 2021

Municipal solid waste (MSW)  is a type of general waste that includes households, traditional markets, commercial areas, and the rest from public facilities, schools, offices, roads, and so on. Refuse Derived Fuel (RDF) is obtained from the remnants of MSW which cannot be used anymore, which is flammable waste and is separated from parts that are difficult to burn through the process of chopping, sifting, and air classification. RDF has potential as an alternative energy source. In this study, RDF fuel was compared with MSW fuel both by proximate and calorific value, then the gasification process was carried out using a multi-stage downdraft gasifier to see gasification performance indicators such as syngas composition, LHV, cold gas efficiency, and tar concentration. The results showed that the gasification performance indicator for MSW biomass resulted in the syngas composition of CO = 19.08% v, H2 = 10.89% v, and CH4 = 1.54% v. The calorific value (Low Heating Value, LHV ) of syngas is 4,137 kJ/kg, cold gas efficiency is 70.14%, and tar content is 57.29 mg/Nm3. Meanwhile, RDF obtained the composition of CO gas: 18.68% v, H2: 9.5446% v, and CH4: 0% v. The maximum LHV syngas is 3365.08 kJ/kg, cold gas efficiency is 57.19 % and the smallest tar content is 80.24 mg/Nm3. When compared to RDF, MSW produces a better gasification performance indicator. However, RDF can still be used as an alternative energy source using the gasification process. The results of this study can be used to optimize the further RDF gasification process.

But in drawing education, mentally retarded persons have different patterns in response to visual meaning. Visual perception is built on coarse motor concepts in processing images which are not always done easily. This research is developed with a descriptive qualitative methodology to see and describe what forms and image models are easy to difficult the draw process. Retrieval of the research data was through mentally retarded children from the Extraordinary School of the Amal Mulia Foundation by processing images in three forms, namely lines, shape models, and combinations of shapes. The preliminary findings in this study were that students with mental retardation had difficulties in drawing shapes that were not straight or solid, such as curves and circles, even though the students were still able to process according to directions in not too long.

Keywords: mental retardation; drawing; visual perception; shape models; education.

Wine is a product of biochemical transformations, compounds present in grape juice, by controlled alcoholic fermentation, that is, effervescence. Grape and yeast enzymes play a key role in the processing of grapes and the preparation of wine, influencing all biotechnological processes of winemaking. Adding liquid or dry active yeast to the wort allows better control of the fermentation process. Under the influence of these yeasts, sugar is converted mainly into alcohol or carbon dioxide, but the yeast itself during fermentation produces many molecules (higher alcohols, esters) that affect the aroma and taste of wine. These transformations take about two weeks and lead to a significant increase in temperature, which must be regulated, not allowing it to rise above 18-20°C: otherwise, some of the aromatic substances may evaporate and the fermentation process itself will stop. The amount of yeast that determines the correct and complete fermentation depends both on the quality of the wort itself, and on the more or less prolonged access of air, the ambient temperature. The air, or rather the oxygen of the air, has a beneficial effect on fermentation as long as there are still many nutrients (sugars) in the wort; as the latter are consumed, extremely small yeast cells are formed, which persist for a long time in the form of turbidity. The rapid course of fermentation can be greatly facilitated by the periodic stirring of yeast, which, settling to the bottom, lose direct contact with nutrients — the lower layers almost do not function. You can mix the wort mechanically or by adding healthy whole grapes to it; in this case, the wort is constantly and automatically mixed: the berries, rising up in the fermenting liquid, carry the yeast with them. In order to speed up the fermentation, the wort is sometimes ventilated, that is, air is introduced into it, by mixing. This article shows the influence of the yeast race on the fermentation dynamics of white grape must, the composition of organic acids and aroma-forming components. The races that ensure the production of highquality wine materials are identified.

The world's oil reserves are decreasing every day due to the continuous production and processing of the most modern technologies. Scientists all over the world are looking for various raw materials and methods to use the vast resources of natural gas as a substitute for petrochemicals. In this regard, great attention is drawn to natural gas as an alternative source of raw materials for petrochemical industries. The purpose of this work is to study the reaction of methane dehydrogenation on new 20%La-10%Ce20%Mg-50% glycine catalysts prepared by the SHS method to identify the optimal conditions for their preparation, concentration and ratio of metals, the influence of contact time and process temperature on the direction and mechanism of the reaction. The results of the study of 20% La-10% Ce-20% Mg-50% glycine catalyst prepared by the SHS method in the process of oxidative dehydrogenation of methane into C2 hydrocarbons are presented. On the basis of experimental studies, it was found that the composition of the catalyst exhibits high activity in the above reaction under the found optimal conditions. Thus, the influence of reaction temperature on the developed composition of catalysts for oxidative conversion of methane has been determined that the optimum temperature for the selective formation of ethane and ethylene is T=700o С. It was found that for selective oxidation of a mixture of CH4: O2 : Ar in C2 hydrocarbons the optimal conditions are: T=700o С, CH4:O2=2,5:1, 5000 h-1.

One of the most important quantities in chemical thermodynamics and thermochemistry is the enthalpy of combustion. Of the currently existing methods for calculating the heat of combustion of natural and synthetic organic compounds, the most acceptable and correct in our case was the Karash method. In this study, the standard enthalpy of combustion, the standard enthalpy of formation, and the melting enthalpy of the antibiotic roseofungin and its cyclodextrin derivatives were calculated. As a result of the study, the thermodynamic constants of the standard enthalpies of combustion, standard enthalpies of formation, and the enthalpies of melting of the above compounds were calculated, which are of interest for physicochemical modeling of processes with their participation, serve as initial information arrays for loading into fundamental thermodynamic data banks and reference books, and is also important for standardization and certification of these complexes. It should be noted that the presence of a large number of hydroxyl groups in the structures of the studied complexes allows them to be attributed to polar compounds.

Using numerousexperimentalandfield researches, it was established that there are rock deformations duringoil and gas fields development, occurred due to thereservoir response. It has been established that formationvolume of pore space is decreased due to elastic expansion of rock grains and increase of compression strength transferred to matrix from mass of overlying rocks due to formation pressure depletion. As the result, there are deformation processes in porous medium accompanied by degradation of its porosity and permeability, and suffered greater change compared to the formation porosity, sufferedpermeability at the samepressure variation. Demonstration of mentioned anomalies under formation conditions leading to non-linear effect can strongly influence the whole process of the reservoir development and lead to various qualitative and quantitative differences between the observed facts and the indicators which were calculated using standard methods. Formulas for determination of debits of incomplete horizontally branched wells (HBW) in deformed formation for various number of horizontal shafts in a battery were obtained in this work using image method of drains (sources) and superposition. Obtainedestimate indicatorscan be used inengineering works during development of the deposits indeformed environment.

Ресурсы углеводородов – это те количества углеводородов, которые существуют в естественных условиях на поверхности Земли или в недрах. При рассмотрении ресурсов оценивают количества углеводородов как в уже известных, так и в еще не открытых скоплениях. Оценки ресурсов направлены на те количества, которые потенциально могут быть извлечены и реализованы на рынке в ходе реализации коммерческих проектов. Система управления ресурсами углеводородов предусматривает систематический подход к оценке количеств углеводородов, оценке проектов и представлению результатов в рамках универсальной классификации. При поведении геолого-разведочных работ (ГРР) неизбежно возникают неопределенности и риски. Прогнозные оценки запасов углеводородов также выполняются в условиях неопределенности. В настоящее время нефтяные компании перед началом выполнения ГРР стремятся минимизировать риски и снять некоторые неопределенности. В целях повышения эффективности проведения ГРР предлагается использовать несколько методов оценки прогнозных запасов по разведочным скважинам. В современном нефтегазовом мире наиболее распространенной является классификация Общества инженеров-нефтяников (SPE) – PRMS (Petroleum Resources Management System) – система управления запасами и ресурсами жидких, газообразных и твердых углеводородов. Технологии поисков и разведки, разработки, добычи и подготовки углеводородов постоянно развиваются и улучшаются. Комитет SPE по запасам нефти и газа (Oiland Gas Reserves Committee, OGRC) находится в постоянном контакте с заинтересованными организациями, чтобы поддерживать имеющиеся определения и методические указания в соответствии с развивающимися технологиями и требованиями промышленности.
