Published: April 2022

The elimination of English subject for elementary school in curriculum of 2013 which has been regulated under the Government of the Republic of Indonesia’s Regulation number 32 year 2013 about the alteration of Government Regulation number 19 year 2005 about National Standard of Education affects on the absence of syllabus as guideline for teaching and learning process. Therefore, on previous study, a set of English syllabus for elementary school was developed to provide English teachers with guideline in teaching. To provide students with closer exposure on local character building, the syllabus was developed based on local value. In the process of syllabus development, try out was done to get feedback on its implementation on the syllabus in the teaching process. Moreover, feedback from teachers’ forum toward the syllabus was also obtained. The feedback received becomes a valuable input toward the improvement of the English syllabus.

Published: April 2022

Abstract To be more proficient and self-regulated, L2 academic writers, the deployment of motivation regulation strategies should be incorporated at the commencement of academic writing learning enterprises, particularly during this pandemic situation. According to previous studies, the establishment of robust motivation regulation strategies will potentially help L2 academic writers to better manage the ongoing writing learning dynamics and cope with varied upcoming challenges. Specifically, this study was conducted qualitatively by lending support from qualitative content analysis in order to offer more overarching findings derived from actual events experienced by the participants. To comply with this objectivity, two research instruments were also utilized in this study namely the Likert-Scale questionnaire and open-ended interviews. Further, the Likert-Scale questionnaire was administered via Google Forms to be filled out by 36 English education master students from batch 2018 and 2019, and the open-ended interview inquiries were sent through WhatsApp application in order to obtain the responses from the three random selected interviewees. Results from this study revealed that the majority of English education master students had successfully become more competent and resilient academic writers through five major streams of motivation regulation strategies namely interest enhancement, performance self-talk, mastery self-talk, self-consequating, and environmental structuring. Keywords: Motivation regulation strategies, academic writing, graduate students, Covid-19 pandemic
LINGUISTIC LANDSCAPE IN A MULTILINGUAL CONTEXT: A CASE OF KENYAN UNIVERSITIES
Authors: Muriungi Stella Wangari , Mudogo Benard Angatia 
Published: April 2022

The linguistic landscape of a place constitutes a clear representation of its language ideology, culture, users’ identity and language practice. These are depicted in verbal language used in public signs including business names, street signs, advertisements and graffiti. The aim of this paper is to examine the language distribution, purpose and authorship of public signage in the multilingual context in Kenyan universities. The paper also examines the students’ attitudes towards the public signs in the sampled institutions. A sample of 185 photos taken from notices, advertisements, building names and posters are analyzed. The analysis reveals that English is the most dominant language used in Universities for both top-down and bottom-up signs, with 77% prevalence. This is attributed to the acceptance of English as a global language and presence of international students and lecturers. A high incidence of informative signs is also noted at 42% of all signage linked with the academic nature of the paper context. The findings also reveal that Kiswahili as an African language with Bantu and Arabic roots is barely utilized in public signs despite its official status. This has implications on language policy and its implementation as it indicates a mismatch between policy and practice.
Adaptive gamification in collaborative location collecting systems: a case of traveling behavior detection
Authors: Dalponte Ayastuy María , Torres Diego 
Published: April 2022

Collaborative location collecting systems (CLCS) is a particular case of collaborative systems where a community of users collaboratively collects data associated with a geo-referenced location. Gamification is a strategy to convene participants to CLCS. However, it cannot be generalized because of the different users’ profiles, and so it must be tailored to the users and playing contexts. A strategy for adapting gamification in CLCS is to build game challenges tailored to the player’s spatio-temporal behavior. This type of adaptation requires having a user traveling behavior profile. Particularly, this work is focused on the first steps to detect users’ behavioral profiles related to spatial-temporal activities in the context of CLCS. Specifically, this article introduces: (1) a strategy to detect patterns of spatial-temporal activities, (2) a model to describe the spatial-temporal behavior of users based on (1), and a strategy to detect users’ behavioral patterns based on unsupervised clustering. The approach is evaluated over a Foursquare dataset. The results showed two types of behavioral atoms and two types of users’ behavioral patterns.

Published: April 2022

Abstract
In this study, nanoiron and nanoiron+Au particles were synthesised using aqueous Aegle marmelos extract using a facile and one-pot approach. Lower size non-magnetic nanoiron (~34 nm) and nanoiron (~34 nm) +Au particles (1 to 1.5 µm) were produced from the same medium individually. Nanoparticles suspension behaviour and structural characterisations were carried out by UV-Vis spectroscopy, electron microscopy and by X-ray diffraction techniques. Primarily, for synthesis, a simple bioreduction approach generated amorphous nanoiron particles, which on annealing produced magnetic maghemite, γ-Fe2O3 type nanoparticles with sizes 100 to 1000 nm. Posteriorly, the bioreduction process also produces nanoiron+Au particles and can be used for multifunctional applications. As a model application, catalytic application of the as-prepared nanoiron and nanoiron+Au particles towards methylene blue, a thiazine dye degradation is investigated and found to be effective within 20 min. Langmuir-Hinshelwood kinetic model was exploited to know the degradation behaviour, and the model was found to be fit based on R
2 values with the observed experimental data. We suggest that the formed highly stable nanoiron particles with in situ stabilisation offer benefits like consistency, environmental friendliness and suits well for large-scale applicability.
Optimisation of Biochar Yield from Sorted Wood Wastes as Sustainable Alternatives to Burning to Ash
Authors: Adeodun Similade A. , Sangodoyin Abimbola Y. , Ogundiran Mary B. 
Published: April 2022

Abstract
Wood wastes are one of the leading contributors of greenhouse gases cum climate change. While the burning of wood wastes results in CO2 emission, decomposition generates methane. In place of these emissions, wood wastes can be converted into biochars which have a lot of novel applications. However, low biochar yield was the common limitation of wood wastes, essentially, due to a mixture of different classifications of trees that pyrolyse at different conditions. In this study, biochar yield from sorted wood wastes was optimised by varying pyrolysis temperature and time. Power consumption, cost, and carbon footprint of the optimised biochar and ash were compared for both hydropower grid and diesel generator scenarios. Optimal pyrolysis yields were 33.6 % (400 °C), 29.4 % (350 °C) and 18.5 % (400 °C) respectively for hardwood sawdust char (HSC), softwood sawdust char (SSC), and mixed sawdust char (MSC) at 2 hours duration for all materials. The CO2 emissions from ash were 2.49 kg and 19.0 kg respectively for grid and diesel power supply. The diesel generator power was 17 times more expensive than grid power for wood wastes pyrolysis. Wood wastes have better biochar yield when charred homogenously; they have a smaller carbon footprint and are cheaper when produced with power from the grid. Wood wastes in place of being burnt can be processed as inexpensive and environment-friendly biochar.
Clogging in Vertical Flow Constructed Wetlands: Causes for Clogging and Influence of Decontamination

Published: April 2022

Abstract
With the continuous operation of constructed wetlands, substrate clogging is issue. In order to solve the problem, there is practical significance to understand the causes for clogging in constructed wetlands. Two pilot-scale vertical flow constructed wetlands were established, namely, CW-B and CW-C. By studying the relationship between the accumulation of different substances and the banked-up water area, it was found that the accumulation of non-filter substances and total solids was an important reason for the clogging of the substrate, and the accumulation degree of non-filter inorganic substances was more obvious than that of non-filter organic substances, and the blockage was mainly located in the 10-20 cm layer. In the vertical flow constructed wetland with river sand as the main substrate, water accumulation will occur when the content of total solid and non-filter substances exceeds 67.233 g and 101.228 g per cubic meter of substrate, respectively. Therefore, it is important to pay attention to the substrate particle size matching of 0-20 cm layer to reduce the clogging in the vertical flow constructed wetland. The clogging has little effect on chemical oxygen demand (COD) removal, but great effect on total phosphorus (TP) removal. Compared with the control wetland (CW-C), the biomass content in the CW-B with biochar increased by 334.26 nmol P/g, which can improve the removal efficiency of total nitrogen (TN) and total phosphorus (TP), but also increase the risk of clogging in the vertical flow constructed wetland. Future research should try to combine the anti-blocking research results of biochar constructed wetlands to improve the purification effect, which is of great significance to promote the sustainable development of constructed wetlands.

Published: April 2022

Abstract
For aerobic static composting, fresh cow, pig, and chicken manures were used as feedstock and mixed with 10 % corn straws, which was considered as the bulking agent. In the composting process of different livestock and poultry manures, the changing trends of temperature, pH, conductivity, density, and other parameters were intensively studied. The results were as follows: (1) after the tail biogases of composting systems - using cattle manure, pig manure, and chicken manure - were introduced into the biofilter, the concentration of O2 decreased slightly, but the concentration of CO2 increased. The odour in these tail biogases declined significantly, and thus the biodegradation of tail biogas was obvious. (2) The oxygen consumption in the different periods of the composting process of these three manures was almost the same, and the average oxygen consumption for the three manures was 0.928, 0.937, and 0.945 m3/kg, respectively. Under standard conditions, the density of oxygen is 1.429 g/L, and the average oxygen consumption in the composting processes of these three manures was 1.326, 1.338, and 1.350 kg/kg, respectively.
Assessing Benthic Macroinvertebrates in Relations to Environmental Variables and Revitalisation Works
Authors: Czerniawska-Kusza Izabela 
Published: April 2022

Abstract
Macroinvertebrates of two ex-manor ponds located in Chroscina, Opole Region (Poland) were studied from 2015 to 2018 to investigate their community composition and diversity and evaluate the heterogeneity of communities on spatial and temporal scale referring to environmental variables and revitalisation work. A total of 32 taxa were recorded (at the family level, except Oligochaeta), 13 of which were Ephemeroptera, Odonata and Trichoptera, recognised as sensitive groups in lentic ecosystems. Macroinvertebrate richness and diversity varied considerably, especially in spring and summer. It was found that habitat heterogeneity influenced benthic invertebrates more than basic water parameters. However, the environmental variables together accounted for only 38 % of the observed variations. Thus, other factors, such as fish predation, may have played a leading role in community shaping. The distinct differences between pond communities, four years after the revitalisation works, resulted more from different habitat features than from the previous sediment removal.

Published: April 2022

Abstract
Ranibari Community Forest (RCF) is the important forest patch present within the highly urbanized Kathmandu Valley with information gaps on soil fauna. This study aimed to explore the soil meso and macrofauna of the forest. Fourteen random quadrats (1 × 1 m2) were laid within seven blocks. Leaf litter samples and soil cores were collected, screened, sieved, and searched under a white sheet, once a fortnight from May to November 2019. The results showed that the diversity, abundance, and richness of soil fauna were the highest in the summer season (H´ = 2.897, abundance = 1,973, S = 84) dominated by Collembola. The Soil Biological Quality Index (QBS-ar) value was also found to be the highest in summer (QBS-ar = 417) and successively decreased in succeeding seasons. Soil fauna was diverse and evenly distributed in soil layers throughout the seasons, but the abundance was greater in leaf litters, particularly in summer. Fauna like Chilopoda, Diplopoda, Haplotaxida, and Isopoda were seen to be affected negatively by soil temperature in summer and autumn seasons. Soil moisture content was found to be positively correlated with immature insects, earthworms, and millipedes in the rainy and autumn seasons. Besides, the pH of the soil was seen to affect Diplura only in the autumn season. The relation of fauna with the physicochemical parameters (temperature, moisture, and pH) and also with other taxa showed their ecological roles and adaptation to a specific microclimate.

Published: April 2022

Abstract
Remotely sensed soil moisture products showed sensitivity to vegetation cover density and soil typology at regional dryland level. In these regions, drought monitoring is significantly performed using soil moisture index and rainfall data. Recently, rainfall and soil moisture observations have increasingly become available. This has hampered scientific progress as regards characterization of land surface processes not just in meteorology. The purpose of this study was to investigate the relationship between a newly developed precipitation dataset, SM2RAIN (Advanced SCATterometer (SM2RAIN-ASCAT), and NDVI (eMODIS-TERRA) in monitoring drought events over diverse rangeland regions of Morocco. Results indicated that the highest polynomial correlation coefficient and the lowest root mean square error (RMSE) between SM2RAIN-ASCAT and NDVI were found in a 10-year period from 2007 to 2017 in all rangelands (R = 0.81; RMSE = 0.05). This relationship was strong for degraded rangeland, where there were strong positive correlation coefficients for NDVI and SM2RAIN (R = 0.99). High correlations were found for sparse and moderate correlations for shrub rangeland (R = 0.82 and 0.61, respectively). The anomalies maps showed a very good similarity between SM2RAIN and Normalized Difference Vegetation Index (NDVI) data. The results revealed that the SM2RAIN-ASCAT and NDVI product could accurately predict drought events in arid and semi-arid rangelands.

Published: April 2022

Abstract
The study presents an algorithm and a mathematical model for evaluating the parameters of the equivalent circuit of an asynchronous electric motor for intelligent monitoring systems. To identify the parameters of electric motors, a gradient descent method is used to find the minimum of a positive function. The algorithm and mathematical model were tested not only theoretically, but also in laboratory experiments. The results obtained proved that the proposed algorithm was an efficient and accurate method for estimating parameters. Computer modelling and experimental research confirmed the possibility of using the algorithm and the device for identifying parameters in the construction of control systems for a variable frequency drive with three-phase asynchronous electric motors in practice.

Published: April 2022

Abstract
To research the improvements of clinical imaging of human tissues, tissue-equivalent materials are one of the reasonable strategies for evaluating the impact of radiation dosages on human tissues. Hence, considering mass and linear attenuation coefficients is a promising method to foresee the appropriate tissue-identical material. In this examination, we utilise the built-up estimations of elemental compositions (mass portion of every component) of PMMA material by numerous analyses in literature. XCOM program was utilised to figure estimations of mass attenuation coefficients of PMMA for various photon energies (0.015–2.0) MeV. The outcomes reveal that the estimations of mass and linear attenuation coefficients are high as the energies begin to decrease and diminish gradually with an expansion in photon energies. Making a sensible coordinating between mass and linear attenuation coefficients of PMMA as human tissue-equivalent material with mass and linear attenuation coefficients of lung, brain, muscle and blood human tissues has demonstrated a phenomenal match.

Abstract
Residual stress measurement in different sorts of mechanical and mechatronic objects has become an important part of the designing process and following maintenance. Therefore, a sufficient experimental method could significantly increase the accuracy and reliability of the evaluation process. Ring-Core method is a well-known semi-destructive method, yet it is still not standardized. This work tries to improve the evaluation process of the Ring-Core method by analyzing the influence of the necessary geometric parameters of the investigated object. Subsequently, residual stress computation accuracy is increased by proposed recommendations.

Authors: Babinkostova Zoja , Manuseva Nensi , Markovic Snezana 
Published: April 2022

Abstract

Background: Evidence for disturbances in HPA activation and abnormal HPA regulatory mechanisms in schizophrenia is accumulating.

Aim: To compare serum levels of cortisol, DHEA-S and their ratio between patients with schizophrenia and healthy controls and among patients before and after treatment with different types of antipsychotics.

Material and methods: In this clinical prospective study, 60 patients with schizophrenia and 40 healthy age and sex matched control subjects were included. All patients experienced an acute exacerbation of the illness (PANSS: P1 and P3 ≥ 4). Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. Serum levels of cortisol, DHEA-S and their ratio were measured at baseline in all participants and after 3 and 6 weeks, respectively, of the antipsychotic treatment with different types of antipsychotics in patients with schizophrenia.

Results: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels in comparison to the control group. There was no significant difference in serum levels of cortisol, DHEA-S and their ratio between patients treated with different types of antipsychotics (typical/atypical). Serum levels of the analyzed hormones significantly reduce during the 6-week period of examination in both subgroups treated with different types of antipsychotics.

Conclusion: Elevated serum cortisol and DHEA-S in schizophrenic patients might be associated with their role in the pathophysiology of the disorder. There is no significant difference in serum levels of cortisol, DHEA-S and their ratio among the patients treated with different types of antipsychotics.

Abstract
Vaccine-induced thrombotic thrombocytopenia (VITT) is a condition similar to heparin-induced thrombocytopenia (HIT), but it is associated with prior administration of COVID-19 vaccines without prior exposure to heparin. The incidence of VITT is not certain, but it appears to be extremely rare. Reports of unusual and severe thrombotic events, including cerebral and splanchnic venous thrombosis and other autoimmune adverse reactions, such as immune thrombocytopenia or thrombotic microangiopathies in connection with some of the SARS-CoV-2 vaccines, have caused a great deal of concern within the population and the medical community. We would like to present 4 clinical cases of VITT, hospitalized and treated in intensive care unit (ICU) of University clinic of cardiology in Skopje.
