Published: August 2022

The weather data that can be obtained through government institutions is very limited, whereas in order to increase the accuracy of weather predictions a homogeneous and dense distribution of data is needed. Therfore it is necessary to increase the data and the purpose of this research is to create a simple and effective way to encourage the number of weather observations in Indonesia through the STMKG Weather Care program. Forms that are made as easy as for respondents to understand, simple, and don't take the time. Developed using Google Form and distributed via the most popular social media today, namely WhatsApp. The test results showed that social media has the potential to be used to support voluntary weather data. The form made is sufficient so that the respondents make relatively few mistakes in terms of the main content of the form. Moreover, the mistakes that are often made by respondents include filling in ID, and typing sub-districts that require manual correction. Based on the results of voluntary observations spread in almost all provinces of Indonesia with the most incoming data coming from the provinces of Central Java and East Java. Based on the evaluation results of 4 months of testing, weather variations and their predictions can be identified with an accurate distribution, with an average accuracy of 0.79. Differences in methods used in verification may affect accuracy.
Correlation of BMKG with TRMM for daily and monthly rainfall series in Banten region
Authors: Zakaria Ahmad
Published: August 2022

Daily and monthly rainfall data series are necessary data for planning purposes in Civil Engineering and other fields. Incomplete rainfall data often occurs, so that rainfall data must be estimated based on rainfall data from several other nearby locations. The addition of rainfall data can lead to inaccurate planning.

Rainfall data used for planning in the civil engineering sector is usually taken from the BMKG station. This data is taken from the rainfall station above the ground. Besides, that can also produce rainfall data from TRMM. Can take rainfall data from TRMM at all locations according to a coordinate of location. This rainfall data denotes an average rainfall taken from the satellite approximately 250 meters above the ground surface.

An equation will be obtained by comparing the daily and monthly rainfall data from the two data sources. Based on TRMM rainfall, we can use the equation to estimate ground rainfall in a location.

In this study, daily rainfall, monthly rainfall, the spectrum of daily and monthly rainfall data from BMKG are compared with rainfall and the spectrum of daily and monthly rainfall data from TRMM. The analysis results show that the monthly rainfall data from TRMM and BMKG correlate better than daily rainfall data.

The best composition of silica sand pellets occurs in the amount of tapioca 3% and with an activation temperature of 250?C, which can increase the acceleration by 12.45% at an acceleration of 0 – 80 km/hour.
Typical islands, borrowed islands: Epistemological and intellectual decolonialization in island studies
Authors: Hong Gang
Published: August 2022

In the emerging scene of non-western island studies, research done on the sinophone world mainly (but not exclusively) by sinophone scholars has become a conspicuous strand in the literature. Despite the diverse locations in focus, most research tends to functionally apply rather than organically engage with west-inflected island theories. Starting from this premise, I embark on a series of critical reflections on the multilayered and intersecting subjectivities of the non-western island researcher and the related challenges in the context of epistemological decolonialization by analyzing two symptomatic narrative vignettes abstracted from my own research experiences in local island and archipelagic areas in China. Specifically, I argue that in the face of intersecting structures and conflicting forces, the non-western island researcher is both stranded and enabled by a series of in-between conditions in which epistemological innovation is difficult, but still possible if pursued through relentless interrogation of one’s own vested interest and constant realignment of positionality. In the end, I propose three ethical-epistemological traps for non-western scholars practicing island research under the shadow of western intellectual hegemony.

Time-frequency representation, which has been widely used in seismic data inquiry, can reveal a parcel of useful data hidden inside the seismic data. We've introduced a previously unexplored seismic application of the high-resolution Time-Reassigned Synchrosqueezing Transform (TRSST), which can provide significantly sparser time-frequency representation than other methods. One of the most appealing aspects of the proposed technique is its ability to be entirely adaptable. For the flag examination representation and deterioration, various approaches have been presented. This paper used the TRSST to provide the time-frequency contour and stimulate the depiction of low-frequency shadows associated with hydrocarbons. It was also compared to the Short Time Fourier Transform (STFT), both of which are STFT-based time-frequency transforms.

Published: August 2022

The purpose of this aims to examine whether those four types of financing respectively impact ROA, revenue, and ROA through revenue at Islamic Commercial Banks in 2017-2020. This quantitative associative study analyzes data using the SPSS version 25 program. Also, SOBEL, a macro developed by Andrew F. Hayes which is integrated with SPSS, is used for testing the mediation effect. The population includes all Islamic Commercial Banks with samples of Islamic banks performing the transaction of the four financings are Bank Muamalat Indonesia, Bank Mandiri Syariah, BNI Syariah, BRI Syariah, Bank Jabar Banten Syariah, BCA Syariah, and Bukopin Syariah. The study shows that those financings simultaneously have a positive effect on ROA and revenue. In addition, revenue is able to mediate the influence of murabahah, mudharabah, and ijarah financing on ROA, but it fails to mediate musyarakah. This study concludes that the four financings are the factors that can affect the rise and fall of the ROA value and revenue of Islamic banks from the distribution of financing.

Authors: Ayoub AA , Cheung GS-P
Published: August 2022

Aim: The purpose of this study was to determine the efficacy of several irrigants and an aqueous extract of Fructus mume in eradicating three kinds of biofilm. Materials and Methods: A three-species biofilm of E. faecalis, P. gingivalis and F. nucleatum were cultivated for one week on Thermanox™ plates. Each specimen was immersed for 8 minutes in various irrigants: Fructus mume solution, buffered citric acid, sodium hypochlorite and control (non-irrigated). LIVE/DEAD® BacLightTM staining and confocal light scanning microscopy were used to determine the number of viable bacteria left on the substrate. The same biofilm was then extracted and subjected to scanning electron microscopy (SEM). Results: Images were taken at 12 locations across the biofilm, which were then classified into four areas of concern: Bottom, which would spend the most of the experiment submerged in the solution; It was struck in the centre by the stream of irrigant.; Middle and Upper, where the impression was caused by the irrigant splattering or vaporizing. Results of the amount of viable bacteria residual indicated that Fructus mume showed no significant activity, with an effect like control and even buffered citric acid, and significantly inferior to sodium hypochlorite. Conclusion: Sodium hypochlorite (0.5%) solution was greater to buffered citric acid, Fructus mume and control group as an antimicrobial agent against three-species biofilm.

Published: August 2022

Objectives: This study aimed to determine the shape of dental inclination between Class I malocclusion and bimaxillary protrusive Malay patients using geometric morphometric analysis obtained from lateral cephalometric radiographs. Materials and Methods: 128 Malay patients who met the inclusion criteria were recruited; of which 64 patients were in Class I malocclusion and another 64 patients in bimaxillary protrusion groups. Samples were in the age range of 18 to 40 years old, with a gender distribution of 41 males and 87 females. Pre-treatment orthodontic lateral cephalometric radiograph were traced and digitized. Thirteen landmarks of each radiograph were incorporated and converted into coordinates using TPSUtil software. The plots were then exported to MorphoJ Software for multiple Geometric Morphometric Analysis (GMA). Results: The results showed that there was a statistically significant difference (p<0.01) in shape of dental inclination between the groups. Discriminant analysis and cross validation of these groups demonstrated 98% accuracy in identifying two types of dental malocclusion. The grid graphs illustrated the shape of dental inclination of the bimaxillary protrusion group as being significantly more proclined when compared to Class I malocclusion. Conclusion: This study concludes that the dissimilarities in dental inclination are identifiable in Class I malocclusion and bimaxillary protrusion and the shape differences can be visualized using geometric morphometric analysis.

La Odisea homérica y el Adán Buenosayres de Leopoldo Marechal en Voyant Tools
Authors: Cutuli Graciela
Published: August 2022

El objetivo de este ejercicio es valerse de las herramientas de visualización de Voyant Tools (voyant-tools.org) para extraer algunas estadísticas sobre vocabulario –palabras más frecuentes, distribución de ciertos vocablos a lo largo del texto dado, tendencias de colocación más habituales– en dos obras literarias: la Odisea homérica y el Adán Buenosayres de Leopoldo Marechal. Se trata de una exploración muy preliminar en busca de la eventual identificación de semejanzas y diferencias terminológicas (así como el relevamiento de tendencias no comparativas dentro de cada documento), ya que si bien hay grandes distancias entre ambos –en primer lugar, por mencionar lo más evidente, porque se está comparando una obra traducida del griego con otra escrita originalmente en castellano–, también hay una alusión constante al viaje odiseico entretejida en la novela de Marechal que habilita el interrogante.

THE IMPORTANCE OF PEDAGOGIC PROVISIONS OF “NAKHASHAVIGH” TEXTBOOK BY KH. ABOVYAN IN MODERN CONDITIONS OF TEACHING
Authors: KHALATYAN GAYANE
Published: August 2022

The article discusses the role of Kh. Abovyan’s “Nakhashavigh” textbook in Armenian school and pedagogy. Abovyan rejected the textbooks in Grabar and created manuals based on humanistic ideas. The educator worked out a new methodology: didactic, psychological and pedagogic system. According to Abovyan, the primary provision of pedagogy is lesson goal, choice of appropriate method, principles of teaching, content of lesson. The suggested provisions are among the priorities of modern educational system.  The comments dedicated to didactic principles are highly appreciated in Abovyan’s legacy and they haven’t lost their theoretical and practical value.

In “Nakhashavigh” textbook the author paid much attention to the visibility as a didactic principle. According to the author, what is seen, felt gives content to the words and notions learnt.  Abovyan connects teaching the native language with developing in students the principle of consciousness and the ability of thinking on their own. He used the principle of consciousness in didactics. According to Abovyan, teaching native language is connected both with logics and activation of psychological processes. 

Our goal is to apply Kh. Abovyan's leading pedagogical didactic principles in the modern education system which will contribute easy perception of academic material and use of modes by teacher.
FRANÇOIS DELSARTE’S DOCTRINE AS THE BASIS FOR THE CREATION OF MODERN DANCE
Authors: PIPOYAN RIMA
Published: August 2022

The article discusses the study of the teachings of François Delsarte, in which an attempt is made to understand the stages of the origin and development of modern dance in different countries. This teaching spread to two countries: the USA, Germany, then it penetrated into Russia and became the basis for the creation of rhythmic and plastic dance studies. All the ideas embodied in the study of the François Delsarte system served as a good basis for the development of a new dance direction at the end of the 19th century. Today, this new dance direction is known to all of us as modern dance. Each country, having its own customs, worldviews and history, interpreted it in different ways: in the USA it was called modern dance, in Germany - expressive dance, and in Russia -  rhythmoplastic dance. These phrases had different purposes: several generations of modern dancers in the USA used their ideas and developed the terminology of modern dance in English. Germany had its own interpretation, but since it was not a widely used international language, the terms did not come into use. Today, in Germany and elsewhere in Europe, these terms are also used in English.

The study was carried out on the availability of laboratory facilities in teaching of Basic Science on the Students’ academic performance in Upper Basic Schools, Kwara State, Nigeria. This target population for the study was all Basic Science Teachers in Kwara State, Nigeria, four hundred and sixty-nine (469) Public Upper Basic Schools and three hundred and sixty two (362) private schools are available in the study area. The researcher designed teachers' questionnaire and was administered to two hundred and thirty six (236) Basic science teachers that were selected from forty-seven Upper Basic Schools (47) from both public and private schools in Kwara State. Researcher-designed validated questionnaire was used to extract data from the respondents on the teachers 'influence on the performance of students in Upper Basic Schools. Three research questions were raised with two hypotheses which were tested. Percentage and t-test statistics were used to analyze the facts collected. The finding showed that influence of Basic science teachers on the performance of students in Upper Basic Schools in Kwara State, Nigeria was significantly. It was also significant based on gender and on year teaching experience of Basic science teachers. According to the findings, it is suggested that; the educational authorities and the school system should encourage the use of available resources by providing for them, the necessary materials that will influence Basic Science performance and enhance students learning. Basic Science teachers should re-assess their classroom instructional practice because there is a need for them to shift from instructional practice that will give the male and female teachers’ equal opportunities to excel in instructional activities. The less-experienced Basic Science teachers should be allowed for cognate experience and help encourage the experience to acquire more experience.

Important environmental problem of some northern regions of Ukraine is the accumulation of heavy metal salts in the soil, water and air, which is observed in various combinations depending on the region and causes adverse effects on population’s health. The central link, in particular the pituitary gland, is involved in triggering a stress response, limiting its further development preventing adverse effects on the body. The study of morphofunctional rearrangements in the pituitary gland of adult male rats under the influence of heavy metal salts complex on the body remains a relevant aspect of modern morphology. The experiment was performed on 12 white mature male rats weighing 200-250g at the age of 7-8 months, which were divided into 2 groups (control and experimental). The experimental group included rats, which after 90 days of use of a heavy metals salts complex (zinc, copper, iron, manganese, lead and chromium) for 30 days used ordinary drinking water. General morphological (histological, morphometric), mmunohistochemical, biochemical and statistical research methods were used. Results showed a decrease in the linear parameters of the adenohypophysis, there was a significant increase in the value of fibrous connective tissue component in the stroma, increased collagenization of large vessels, significant diffuse stromal edema and edematous processes in the gland parenchyma persisted. Measurements revealed an increase in the number of chromophobes and at the same time a decrease in the number of chromophilic basophils compared to control animals, the presence of cysts in the parenchyma was found out. number of morphological features still indicated the development of adaptive and compensatory processes in the adenohypophysis (vascular plethora decreased, significantly improved the rheological properties of blood, an increase in the number of adenocytes with increasing expression of hsp90 in their cytoplasm). However, despite the positive dynamics of adaptive processes, it should be noted that the 30-day period of adaptation is insufficient for complete recovery of the organ.

Geometries of camptothecin, irinotecan, SN-38, and of their hypothetical Cu(II) complexes were optimized at the B3LYP/6-311G* level of theory. Their electron structure, evaluated in terms of Mulliken population analysis and Quantum Theory of Atoms-in-Molecule, was subsequently related toin vitrocytotoxicity. Electron density transfer from the relevant active sites to Cu decreases in the sequence irinotecan > SN-38 > camptothecin. The absolute values of their metal-ligand interaction energies exhibit the same trend. Discrepancy with the least relativein vitrocytotoxicity of irinotecan can be explained by differences in its pharmacokinetics.

Young rabbits does fed ad libitum diets often show parturition problems such as dystocia and abnormal presentation, resulting in reduced numbers of kits. This can be linked to excessive fatness of the does. Several studies have documented the effect of feed restriction on rabbits, but only limited information exist on the carryover effect of maternal feed restriction exerts on meat quality attributes of the offspring produced from such restriction. This study evaluated the influence of maternal feed restriction and vitamin E inclusion during pregnancy on meat quality of rabbit kits. Seventy-five rabbits, consisting of sixty 20-week-old does and 15 mature bucks, were used in the experiment. Treatments consisted of two levels of feed restriction (0 and 15 %) applied at three different periods during pregnancy (15 – 19, 20 – 24, or 25 – 29 days) with or without vitamin E dietary inclusions (0 and 300 mg/kg). The pregnant does were divided into twelve treatment groups, each containing five replicates of one rabbit each. The experiment was in a 2 × 3 × 2 factorial layout in a completely randomised design. After kindling (between days 28 – 31 of pregnancy) the resulting kits (a total of 180 kits) were arranged on treatment basis of their mothers and managed for a period of 56 days; that is 15 kits per treatment, each replicated 5 times (each replicate contained 3 kits). After 56 days of experiment, the data were collected on meat pH, total cholesterol, crude fat, crude protein, thermal shortening and refrigeration loss. Feed restriction during pregnancy with or without dietary vitamin E (no addition and 300 mg/kg) resulted in a significant (p < 0.05) influence on meat quality attributes of growing rabbits as total cholesterol (555.00 ± 6.06) decreased in the meat of rabbits whose mothers were feed-restricted during pregnancy. On the other hand, maternal feed rationing with or without vitamin E did not significantly (p > 0.05) affect the crude protein and thermal shortening of their slaughtered offspring. In conclusion, maternal feed rationing during pregnancy can be adopted as a feeding strategy in manipulating meat quality indicators of growing rabbits as total cholesterol concentrations decreased which is a good indicator that the meat is safer and better for consumers in order to prevent health-related challenges.

The ANOVA analysis was performed to calculate the each factor percentage contribution on the dye removal efficiency. A desorption study was carried out to evaluate the regeneration possibility of the used adsorbent. The removal efficiency ranged from 5.91 to 94.48 % depending on the controllable factors combination set by Taguchi design. The results showed that the factor with the highest percentage contribution on the dye removal efficiency was the ionic strength (48.85 %). The correlation between the predicted values of the dye removal efficiency with those obtained experimentally indicate a good accuracy of Taguchi approach.

Study aim: To assess the impact of the COVID-19 pandemic on health, lifestyle, training loads and competition starts of swimmers in Poland in 2020.

Material and methods: The study was conducted in the form of a questionnaire on group of 123 Polish swimmers in 2020. The survey asked about differences in training, lifestyle and well-being following the introduction of pandemic restrictions. The mean age of the athletes was 23 years ± 7.6 and training experience 10 years ± 5.3.

Results: The majority of swimmers (81%) were satisfied with their health status. Respondents did not experience changes in sleep quality and length during the COVID-19 pandemic. A large proportion of respondents (83%) did not follow a special diet, while they were willing to use supplementation (58.5%). Respondents stated that the pandemic did not affect their physical activity outside of training. The athletes evaluated negatively the changes in training and competition conditions caused by the pandemic (p < 0.0001).

Conclusions: The study showed that the COVID-19 pandemic did not have a major impact on the health, sleep and physical activity of swimmers in Poland in 2020, while it had a negative impact in terms of training conditions and sport competition.
New approach to estimating macroeconomic determinants of informal employment
Authors: Vidović Nikola , Ritan Vladana
Published: August 2022

Informal employment is a less favourable type of employment whose levels policy makers usually want to decrease and move these workers in the formal part of the labour market. It is more commonly found in LDCs and in developing economies, than in developed ones. This paper uses a cross-section multiple regression analysis to check the effects of multiple macroeconomic variables on the size of the informal labour market. The sample is made out of economies for which ILO has published data about the share of employment outside the formal sector, excluding the economies that receive aid from IDA, using 2017, 2018 and 2019 data from the International Labour Organization and other international organizations. Results show that macroeconomic variables do not have significant explanatory power, except for unemployment rate, exports and GDP growth rate.
Biomass allocation and carbon stock in Douglas fir and Norway spruce at the tree and stand level
Authors: Čihák Tomáš , Vejpustková Monika
Published: August 2022

The effect of changing tree species composition in favor of a greater representation of Douglas fir at the expense of Norway spruce on the carbon pool of Central European forests has not yet been investigated. Here, we compare the allocation of aboveground biomass and carbon stock in Douglas fir and spruce at the tree and stand level. At the tree level, Douglas fir accumulated, on average, 16.9% more aboveground biomass than Norway spruce. A greater amount of biomass was allocated mainly in the wood and bark of Douglas fir stem. For these biomass compartments, the difference between Douglas fir and Norway spruce was 21.1% and 60.3%, respectively. Spruce allocated more biomass in the crown, where the difference was 25.6% compared to Douglas fir. In needle biomass, Norway spruce exceeded Douglas fir by 84%. At the stand level, the analysis of model stands revealed that pure Norway spruce stands accumulated more carbon in the high and medium quality sites. As the site quality decreased, so did the differences in the amount of stored carbon. The higher carbon sink in Norway spruce stands was also confirmed in the analysis of real Norway spruce and Douglas fir stands. The difference in the carbon stock of young, medium-aged, and mature stands was 11.5%, 14.8%, and 1%, respectively. The positive balance in favor of spruce is mainly due to significantly higher numbers of trees per ha in Norway spruce stands. A positive effect of a greater representation of Douglas fir on the carbon budget of forest stands was not confirmed.
Biomass distribution, allocation and growth efficiency in European beech trees of different ages in pure even-aged stands in northeast France
Authors: Le Goff Noël , Ottorini Jean-Marc
Published: August 2022

Determination of the biomass and biomass increment of trees in managed stands is a pre-requisite for estimating the carbon stocks and fluxes, in order to adapt the forests to new climatic requirements, which impose to maximize the CO2 retained by forests. Tree biomass and biomass increment equations were formerly developed in two young experimental beech stands in the Hesse forest (NE France). To extend such a study to beech stands of different age classes, it was necessary to build biomass and biomass increment equations that could be used for any age, called generalized biomass equations. For that, trees were sampled in plots covering a large age range in Hesse forest, and in each plot several trees were chosen to represent the different social classes. Compatible biomass and biomass increment equations for the different tree compartments and their combination in above and belowground tree parts were developed and fitted, allowing the analysis of the variations of the biomass distribution and allocation with tree age. Stem growth efficiency (stem growth per unit of leaf area) appeared dependent on tree age and tree social status. The biomass and biomass increment equations established for beech allow the estimation of the biomass and carbon stocks and fluxes (NPP) for the even-aged beech stands of the Hesse forest, whatever their age. These equations could also be used to analyze the effects of silvicultural treatments on the biomass and carbon stocks and fluxes of beech stands, using the available stand growth and yield models of beech.

In a previous study, the topsoil and root zone ASCAT satellite soil moisture data were implemented into three multi-objective calibration approaches of the TUW hydrological model in 209 Austrian catchments. This paper examines the model parametrization in those catchments, which in the validation of the dual-layer conceptual semi-distributed model showed improvement in the runoff simulation efficiency compared to the single objective runoff calibration. The runoff simulation efficiency of the three multi-objective approaches was separately considered. Inferences about the specific location and the physiographic properties of the catchments where the inclusion of ASCAT data proved beneficial were made. Improvements were primarily observed in the watersheds with lower slopes (median of the catchment slope less than 15 per cent) and a higher proportion of farming land use (median of the proportion of agricultural land above 20 per cent), as well as in catchments where the runoff is not significantly influenced by snowmelt and glacier runoff. Changes in the mean and variability of the field capacity parameter FC of the soil moisture regime were analysed. The values of FC decreased by 20 per cent on average. Consequently, the catchments’ water balance closure generally improved by the increase in catchment evapotranspiration during the validation period. Improvements in model efficiency could be attributed to better runoff simulation in the spring and autumn month. The findings refine recommendations regarding when hydrological modelling could consider satellite soil moisture data added to runoff signatures in calibration useful.

The goal of this study was to evaluate the effect of products from a municipal wastewater treatment plant on the H2O and CO2 effluxes from two soils. The net H2O and CO2 effluxes were measured at the surface of nine beds with two different soils (Cambisol and Arenosol) and two crops (maize or vegetables). Soils in some beds were amended with stabilized sewage sludge (bed with Cambisol and maize) or composted sewage sludge (two beds with Cambisol and both crops) or were irrigated with treated wastewater (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). Remaining beds were irrigated with tap water (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). While stabilized and composted sewage sludge positively affected the CO2 emission, the effect of treated wastewater was not confirmed. Different treatments had negligible effect on the water efflux, which was mainly affected by the plant canopy that influence the temperature of the soil surface. Statistical analyses showed that trends of the CO2 efflux with respect to various scenarios measured on different days changed during the season. No significant correlations were found between the average H2O and CO2 effluxes and measured soil properties.

This paper reviews the effects of iron-based powder on shape accuracy of injection moulded parts. Analysed specimens were produced on a micro injection moulding machine. At first, specimens of pure polypropylene (PP) were manufactured. Then specimens containing 1, 2 and 3 vol. % of iron powder additive were produced using the same process parameters. Subsequently, the samples were scanned using scanned using Zeiss METROTOM CT scanner. Results were analysed via CAE inspection tools. The main aim was to compare the shape and flatness of the scanned specimens to the nominal models. Results showed that iron-based additives of this vol.% had no significant effect on shape accuracy of produced parts. This paper is a partial result of the ongoing research focused on effect of iron and steel-based additives on material, magnetic and mechanical properties of polymers.

Titanium grade 2 plates were modified by a pulsed nanosecond laser beam. The aim was to determine the surface properties after the machining process in two different liquid media. The samples were processed in distilled water and paraffin oil. It was found that a surface with half-surface roughness values with a number of cracks was formed in distilled water. The presence of water reduced the size of the heat-affected zone.
