Geological Science and the Making of Colonial Oil Frontiers on the East Coast of Sumatra, 1890-1930
Authors: Harnawan Tedy
Published: April 2024

In the early 20th century, the Dutch Empire emerged as a prominent oil producer internationally, with the Netherlands East Indies leading the way in petroleum production. The colonial petroleum industry’s success was bolstered by scientific and technological advancements that streamlined the oil exploitation process. Geology played a critical role as a scientific tool that facilitated the conquest of landscapes and crude oil control along Sumatra’s east coast. The study of geology supported the colonial oil politics, leading to a new era of oil mining exploitation through robust economic partnerships between the Dutch colonial government and private oil companies. This paper aims to explore the link between Dutch colonial scientific agency and the establishment of an oil extraction territory that transformed the natural environment and social conditions on the east coast of Sumatra, from Aceh to Palembang.

ENERGY PROPERTIES OF SYMMETRIC DEFORMABLE SYSTEMS
Authors: Stupishin Leonid , Mondrus Vladimir
Published: April 2024

Energy methods for calculating structures, which have become popular for a century, are based on the Lagrange principle and have the meaning of equality of work of external forces and internal forces. Having proved their effectiveness in the overwhelming majority of problems of structural mechanics, they became the dominant approach in formulating the problems of studying solid deformable systems and gave rise to the main methodology for solving problems. As a result, a situation has arisen that the internal potential energy of a deformed body remains insufficiently studied.

The paper develops an approach to the study of the symmetric structure at critical levels of strain energy. The criterion of critical levels of strain energy, based on the concepts of "self-stress" ("self-balance") of a deformable body. Limiting values of the structure strain energy may get by varying the reactions and deflections in the nodal points. The extreme values of forces and displacements of the rods are calculated in matrix form from the values of nodal reactions (displacements).

Methodology for studying the energy properties of a system   is shown on the examples of the study of symmetric rod systems without involving the concept of external forces. The technique is based on matrix methods of structural mechanics and the mathematical apparatus of eigenvalue problems. The comparison of structural design and structural analysis solution of structural mechanics tasks by traditional methods and with the proposed methodology is carried out.

Authors: Maghfirah Wulan , Ilyas Ilyas , Yusnizar Yusnizar
Published: April 2024

Ultisol can be used to plant food crops because the land spread is quite wide, but this must be done with proper soil and plant management (Prasetyo and Suriadikarta, 2006). One of the food crops that can be planted on this land is corn. According to the Central Statistics Agency (2018), Aceh's corn production in 2017 was 387,470 tons, while corn production in 2018 was 347,735 tons, which in this case experienced a decline. This research aims to determine the effect of rice husk ash on on soil chemical properties and P-uptake of corn plants (Zea mays L.) in Ultisol. The research used a non-factorial randomized block design (RAK), with 4 treatments and 5 replications so that there were 20 experimental units. The treatment composition was control, 10 t ha-1 rice husk ash, 20 t ha-1 rice husk ash, 30 t ha-1 rice husk ash. The parameters observed were soil chemical properties (pH, P-total of soil, and P-available of soil), oven dry weight of corn plants and P-uptake of corn plants. The parameters were measured at 45 days after planting (DAP). The results showed that rice husk ash had a significant effect on oven dry weight of corn plants, but the effect was not significant on soil chemical properties (pH, P-total of soil, and P-available of soil), and P-uptake of corn plants. Treatment with 20 t ha-1 of rice husk ash gave the best effect on the growth of corn plants.

Marine organisms, including marine plants, are important sources of new
compounds endowed with interesting biological properties. The aim of
this study was to evaluate the antioxidant, antibacterial and analgesic
activities of the hexane, ethyl acetate and methanol extracts of
seagrass Halophila stipulacea (Forssk.) Ascherson (Hydrocharitaceae)
leaves and stems. Antioxidant activity was evaluated by through
2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging ability and
reducing power. Antimicrobial potential was assessed by the minimum
inhibitory concentration (MIC) method. Analgesic activity was evaluated
by the acetic acid method. Methanol and ethyl acetate extracts of H.
stipulacea were found to have the highest phenolic content and showed
higher antioxidant activity than hexane extracts. Stem extracts showed
moderate antimicrobial activity against tested microorganisms (minimum
inhibitory concentration range was 3.75-15 mg/mL). All tested extracts
had a high analgesic activity in acetic acid-induced writhing assay, and
their effects were comparable to the reference acetylsalicylate lysine
drug (200 mg/kg, applied intraperitoneally). The methanol stem extracts
had a higher analgesic effect than acetylsalicylate lysine used as a
positive control, with a maximum inhibition of 84.06±5.47 % vs.
75.73±10.67 % for positive controls. In summary, the investigations
indicate that H. stipulaceais a natural source of antioxidant,
antimicrobial and analgesic activities.

Authors: Luu Hai , Le Linh , Green Iain
Published: April 2024

Spring onion (Allium fistulosum L.) is a popular salad vegetable produced
widely over the world, including in Vietnam. Thanks to its flavor and aroma,
it is an indispensable ingredient used to flavor soups and other dishes.
Vermicompost is a natural and environmentally friendly fertilizer used
widely to increase crop production and maintain the sustainability of
agrosystems. Consequently, this study was conducted to investigate the
efficiency of vermicompost at different application rates in promoting the
growth and yield parameters of spring onion. The results show that adding
vermicompost to spring onion production had significant positive effects on
plant height, number of leaves, number of tillers, individual plant weight,
and plot yield. Particularly, the application of vermicompost at 40 t ha-1
showed the highest performance in the observed parameters, increasing the
number of leaves, number of tillers, individual plant weight, and plot
yields to 64.78, 21.18, 302.96 g plant-1, and 4.86 kg m-2, respectively. The
plot yields in the treatments of the highest and lowest vermicompost
application increased by 49.1% and 3.9%, respectively, in comparison to the
control. Consequently, there was a strongly positive relationship between
the application rate of vermicompost and the plot yield.

Authors: Zhu Shiquan , Peng Yisen , Cheng Chuanxiao , Qi Tian , Zhang Zhenya , Yuhangpeng Y , Li Longjiang , Jin Tingxiang
Published: April 2024

In order to enhance the heat transfer effect and improve the energy
utilization efficiency of the circular tube under turbulent flow, rhombic
and triangular winglet vortex generators are proposed on the basis of
rectangular winglet vortex generator. The effects of three vortex generators
on flow and heat transfer in the tube are investigated by numerical
simulations. The results indicate that, the rectangular and triangular
winglets generate two pairs of longitudinal vortices and the triangular
winglets generate four pairs of longitudinal vortices due to additional
shrinkage regions. The multiple longitudinal vortices increase the mixing
between the fluids, raise the temperature in the central region of the tube,
and enhance the heat transfer effect. Furthermore, the triangular winglet
enhanced tube has the largest direct flow area and the least effect on
resistance. The triangular winglet enhanced tube had the best comprehensive
performance, followed by the rhombic winglet enhanced tube, and finally, the
rectangular winglet enhanced tube. The performance evaluation criterion
(PEC) reached 1.04-1.13, 1.05-1.15, and 1.08-1.21 for the three enhanced
tubes in the given flow rate interval. In addition, the effect of
inclination angle on the triangular winglet enhanced tube was further
investigated, and the results show that the best comprehensive performance
of enhanced heat transfer is achieved at an inclination angle of 45?, with a
maximum PEC of 1.25.

Authors: Yetumyan Luiza A. , Komerova Natalia E.
Published: April 2024

Introduction. Currently, a relevant object of research is the identification of differences in women’s perception of their actual weight and subjective assessment of their body image and self-conception in relation to weight. Since the perception of body image is greatly influenced by fashion trends and beauty standards broadcast in society, women may exhibit different cognitive and behavioral patterns depending on their body mass index.

Objective. To study the relationship between the features of perception of body image and self-esteem in women with different body mass indexes

Materials and methods. The following methods were used in the study: author’s questionnaire-questionnaire of Yetumyan L. A. and Komerova N. A. and Komerova N. E.; Thomas Cash’s Multimodal Body Self-Relationship Questionnaire (MBSRQ, Thomas F. Cash) adapted by Baranskaya L. T. and Tataurova S. T. and Tataurova S. С. The Mann-Whitney U statistic for two independent samples and the r-Spearman rank correlation coefficient were used for mathematical processing of the data.

Results. The study included 137 women with different BMI values ranging from 17 to 72 years of age. The mean age of the respondents was 35 years. According to our questionnaire survey, more than 40 % of respondents had overweight or obesity of the 1st, 2nd or 3rd degree. The results are presented by five scales reflecting the following parameters of attitude to one’s own body: evaluation of appearance, appearance orientation, satisfaction with body parameters, concern about being overweight, self-assessment of weight. The results of comparative analysis in two groups have been described – women with low and normal BMI and women with excessive BMI.

Discussion. Women in groups with different body mass index have differences in their orientation to appearance. Thus, the higher the weight of women with high BMI, the lower they evaluate the level of their attractiveness and the less effort they put into improving their appearance. They are also more indifferent to appearance. No such correlation was found in women with low and normal BMI. The high importance of appearance for women from both subgroups is directly correlated with a high level of concern about excess weight, which indicates an attitude to one’s own weight as one of the factors determining external attractiveness.
Identification of Predictors of a Meaningful Avoidance Strategy
Authors: Godunov Mikhail V. , Portnov Evgeny A.
Published: April 2024

Introduction. In this section the authors present the relevance of the study of the semantic avoidance strategy which is maladaptive when coping with crisis and uncertain situations. We consider the assumption of the presence of predictors of a sense-forming avoidance strategy as a hypothesis that has significant correlations with the scales of the questionnaire for the study of avoidance.

Objective. Presentation of the results of empirical identification of predictors of a meaningful avoidance strategy.

Materials and methods. The author’s verbal questionnaire is presented and applied to study the avoidance strategy. It consists of 9 semantic scales of personality traits to study the specifics of avoidance. To identify its predictors, the battery of tests includes proven methods from the related fields of semantic regulation: the test of life orientations (D. A. Leontiev), the “New Questionnaire of tolerance-tolerance to uncertainty” (T. V. Kornilova).

Results. The indicators for verifying the normality of the distribution of empirical indicators are presented as well as data from the correlation analysis of the battery of tests in the sample n = 282. Empirically established values of the Shapiro-Wilk coefficient have values higher than the required level of statistical significance ,05 for indicators of all scales of this battery of tests. Correlation analysis has established that there are three indicators of the scales of the tested tests, which have values of statistically significant empirical Pearson correlation coefficients with the scales of the author’s questionnaire.

Discussion. Empirically calculated values of the Shapiro-Wilk criterion with respect was based on the satisfaction to a specified level of statistical significance ,05 it was found that all the studied indicators have a normal distribution character. This confirms the representative nature of the sample. According to the results of the correlation analysis conducted at the significance level ,05, the scales “process” and “locus of control – I” of the test “Life orientations” (D. A. Leontiev) were adopted as the main predictors of avoidance, and the scale “tolerance to uncertainty” according to the “New questionnaire of tolerance to uncertainty” was used as an auxiliary predictor (T. V. Kornilova). The stated hypothesis has been confirmed. Limitations of the study – testing did not affect respondents under the age of 18, as well as over the age of 47, and was conducted only for the types of profession “human – human” and “human – sign”. It is possible to conduct low-cost testing and build multifactorial personal avoidance profiles with the help of the identified predictors.
The Relationship of Emotional Intelligence and Psychological Reasonableness of Adolescents with the Peculiarities of Child-parent Relations
Authors: Kagermazova Laura Ts. , Pronenko Evgeny A.
Published: April 2024

Introduction. The article is aimed at studying the relationship of emotional intelligence, as well as psychological reasonableness of adolescents with the peculiarities of the mother’s relationship to the child. The novelty of the study lies in the fact that today in Russian scientific works the topic of psychological intelligence is not sufficiently covered. The study of its connections with emotional intelligence will allow us to understand the relationship between these characteristics for a deeper understanding of the emotional sphere of adolescents, and the study of its connections with the mother’s parenting style will allow us to better understand the process of its formation.

Objective. investigate the interrelationships of emotional intelligence and psychological reasonableness of adolescents with the peculiarities of maternal attitude towards them.

Materials and methods. Adolescents aged 13 to 15 years (n = 43) were studied as an empirical object. To study emotional intelligence, the methodology “Emotional intelligence of adolescents” by Sadokov and Voronkin was chosen, and the “Scale of Psychological reasonableness, SPR/PMS” was used to study psychological reasonableness in the adaptation of Novikova and Kornilova. The “Teenagers about parents” technique was using the peculiarities of the mother’s relationship to the teenager were established.

Results. The emotional intelligence of adolescents tends to be low, while maintaining the average values of psychological reasonableness. Statistically significant negative associations were found between hostility, inconsistency, and criticality of the mother towards the teenager with factors of emotional intelligence and psychological reasonableness. A positive relationship was also revealed between the closeness of the mother with the teenager and his psychological intelligence.

Discussion. The results obtained are confirmed in the concepts of other authors. Thus, the preservation of an average level of psychological intelligence with low emotional intelligence of adolescents is explained by the abundance of psychological information in the Internet space in which adolescents spend most of their time. Data on the negative relationship of hostility and criticism of the mother with the peculiarities of emotional intelligence and psychological reasonableness are also confirmed: parents who reject, ignore and criticize a teenager can mainly raise teenagers with a low level of emotional intelligence who do not seek to discuss their problems.

Authors: Zvezdina Galina P.
Published: April 2024

Introduction. Currently, the relevant object of research is the studying of psychological determinants that contribute to the formation of computer gaming addiction in children and adolescents. The younger school age is the least studied in terms of familiarization with the Internet environment and, in particular, computer games. The identification of psychological determinants that contribute to the formation of gambling addiction among younger students is an urgent problem in connection with the prevention of the formation of destructive behavior even at the early stages at school.

Objective. Identify psychological determinants that cause the formation of computer gaming addiction in younger schoolchildren.

Materials and methods. A sample of an empirical study was made up of students of 3 classes of the city school, in the amount of 78 people, the average age was 9.8 years. To achieve the goals of the study, the following methods were used: a test questionnaire of the degree of enthusiasm for computer games by A.V. Grishina; methodology “Computer game addiction” by O. M. Vidova; Technique “What is good and what is bad”, adapted by N.V. Kuleshova. For mathematical data processing, the Mann-Whitney U test and the r-Spearman rank correlation coefficient were used.

Results. According to the conducted psychological testing, three groups of younger schoolchildren with different levels of computer gaming activity were identified – low, medium and high. According to the criteria of the questionnaire “The level of computer gaming addiction”, a high level, which correlates with computer gaming addiction, was detected in 26.1 % of respondents. The results of a comparative analysis of the severity of indicators of computer game addiction are described.

Discussion. It was found that groups with different levels of computer gaming activity differ in the degree of enthusiasm for computer games. So, the higher the level of gaming activity, the higher the level of emotional attractiveness of computer games and focus on gaming activities, and the lower the self-control of gaming behavior, that all is the inability to independently complete gaming activities. The results obtained are indicated that these psychological characteristics are the determinants of computer gaming addiction in younger schoolchildren.

Authors: Jabbar Muhammad , Nasar-u-Minallah Muhammad , Yusoff Mariney Mohd
Published: April 2024

Land use changes significantly threaten urban areas, especially in developing countries such as Pakistan, impacting the thermal environment and comfort of human life. The ongoing transformations in cities such as Lahore, the second largest and rapidly expanding urban center in Pakistan, are alarming due to the removal of green cover and the disruption of ecological structures. In response to these concerns, this study was conducted to assess and predict the implications of observed land use changes in Lahore. The analysis employed three Landsat images from 1990, 2005, and 2020, using ArcGIS and Idrisi Selva software. The results show that the built-up area increased almost 100% (16.44% to 32.48%) during the last three decades. Consequently, a substantial shift from low to medium and medium to high degrees of LST was observed. The projections indicate a further 50% expansion of the built-up area, encroaching upon green cover until 2050, shifting more areas under a higher LST spectrum. So, the study concludes that Lahore is facing imminent threats from rapid land use changes caused by higher land surface temperature in the study area, necessitating prompt attention and decisive action. The study area is at risk of losing its conducive environment and the desirable uniformity of the thermal environment. Therefore, it is recommended that green cover be strategically enhanced to offset the rise in built-up areas and ensure a sustainable thermal environment.

Published: April 2024

Forest fires are global phenomena that pose an accelerating threat to ecosystems, affect the population life quality and contribute to climate change. The mapping of fire susceptibility provides proper direction for mitigating measures for these events. However, predicting their occurrence and scope is complicated since many of their causes are related to human practices and climatological variations.  To predict fire occurrences, this study applies a fuzzy inference system methodology implemented in R software and using triangular and trapezoidal functions that comprise four input parameters (temperature, rainfall, distance from highways, and land use and occupation) obtained from remote sensing data and processed through GIS environment. The fuzzy system classified 63.27% of the study area as having high and very high fire susceptibility. The high density of fire occurrences in these classes shows the high precision of the proposed model, which was confirmed by the area under the curve (AUC) value of 0.879. The application of the fuzzy system using two extreme climate events (rainy summer and dry summer) showed that the model is highly responsive to temperature and rainfall variations, which was verified by the sensitivity analysis. The results obtained with the system can assist in decision-making for appropriate firefighting actions in the region.

De ser una realitat rellevant durant la segona meitat del segle xx, encara que de caràcter episòdic i mirada domèstica, la diplomàcia subnacional als Estats Units ha transitat amb el nou mil·lenni cap a nous esquemes multiactor, més complexos, sofisticats i amb major capacitat d’impacte; esquemes en què algunes organitzacions filantròpiques, el sector privat, think tanks altament influents i l’acadèmia tenen un pes molt significatiu. Avui, l’ambaixadora Nina Hachigian, representant especial dels Estats Units per a la diplomàcia de ciutats i estats, lidera una estratègia que busca guanyar influència al Departament d’Estat amb l’objectiu de situar els governs subnacionals com a peces de pes a l’engranatge de la diplomàcia estatunidenca. Caldrà veure’n l’evolució, sobretot amb Donald Trump a l’horitzó.

Larval erythraeid mites of the genus Leptus Latreille, 1796 are common ectoparasites of terrestrial arthropods, including harvestmen (Order Opiliones). In this study, we investigated sexual, ontogenetic, and geographic variation in infestations of the Neotropical cosmetid harvestmen Erginulus clavotibialis (Cambridge, 1904) by larval mites across multiple sampling locations in Belize. We did not observe any significant differences in the prevalence or intensity of mite infestation with respect to sex of the host or between juveniles and adults. However, there was significant variation in the prevalence of infestation between field sites, varying from 18-71%. The overall mean intensity of infestation was 3.2 mites/host. Larval mites exhibited a non-random distribution with respect to attachment sites, with significantly more mites occurring on femur IV. Larval mites were absent from the tarsi of the walking legs and were rarely observed attached to the pedipalps or chelicerae of the harvestmen. Of the ten mites attached to hosts that were examined with SEM, six larvae were found in close association to abandoned attachment cones.

In this paper, we have performed first-principles calculations on the structural and optoelectronic properties of Cu2GeS3 compound in the Cc and Imm2 structures. We have applied the linear augmented plane wave method for all electrons (FPLAPW), which is based on density functional theory (DFT) by using the local density approximation (LDA) and the Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation (GGA). In addition, the modified Becke Johnson Tran and Blaha potential (TB-mBJ) combined with the Hubbard potential (U), which successfully corrects the band gap problem.

The structural properties such as lattice parameter, compressibility modulus and its derivative for Cu2GeS3-Cc are in good agreement with the available data, but for Cu2GeS3-Imm2 there is no research work in the literature. The band structure results show that the Cu2GeS3-Cc compound has a direct gap (Γ-Γ) and that Cu2GeS3-Imm2 is a metal.

The optical properties are calculated by determining the real and imaginary parts of the dielectric function ε(ω), the absorption coefficient, the reflectivity and the refractive index. These results indicate that these alloys are very useful for UV photo catalysis applications.

Authors: Major-Godlewska Marta
Published: April 2024

The structure and size of droplets of the inner phase of a multiple emulsion and rheological properties of the produced multiple emulsion are presented in this paper. The multiple emulsion was produced in a stirred vessel equipped with four baffles. In the study, two different stirrers: turbine impeller and Rushton turbine impeller were used. The liquids used in the produced multiple emulsion were: distilled water and refined sunflower oil. 8 g and 16 g lecithin from soya beans were used as an emulsifier. The preparation time was respectively 15 min. and 45 min. The structure of the obtained emulsions is presented in the form of photos taken with the diagnostic inverted microscope. The results size of droplets were presented in the form of graphics as a distribution of drops. The rheological properties of the multiple emulsion were presented graphically and it was described using the rheological model.
Coupled action of ozone and UV radiation towards obtaining adipic acid from cyclohexane/one

Published: April 2024

A lot of research is constantly underway in the world to develop new or improve the current processes of the chemical industry to make them more effective and environmentally friendly. The described research on the oxidation of cyclohexane or cyclohexanone to adipic acid with a coupled action of UV radiation and oxygen–ozone mixture, instead of the currently used oxidation with HNO3, is part of this trend. Gas chromatography was used to determine process indicators, such as cyclohexane conversion and selectivity to AA, which exceeded 50% at 25 oC, after 16 h. This method can also be used for the preparation of other dicarboxylic acids from cycloalkanes, which proves its universal character.

Published: April 2024

A novel series of 1,3,4-oxadiazole derivatives of mefenamic acid was obtained by reacting hydrazones of mefenamic acid with anhydrous acetic anhydride. The mefenamic hydrazones were obtained by reacting different substituted aldehydes with mefenamic acid hydrazide. All the compounds were characterized by spectral data and elemental analysis. Molecular docking studies of all the compounds were performed against COX-1/COX-2 enzymes. Compound 4 and compound 10 were found to have the highest potential to bind with COX-1 while compound 3, compound 6, and compound 10 were found to have the highest potential to bind with COX-2 enzyme.

Objective: To assess the influence of affective actions on senior high school students' perceptions and behaviors regarding climate change, including mitigation, adaptation, and policy support; and provide insights for educators, administrators, and policymakers on integrating affective learning strategies into climate change education to promote long-term engagement and action.
 
Theoretical framework: This study is anchored on the Affective Domain of Learning by Krathwohl, Bloom, and Masia (1964).
 
Method: This study utilizes a descriptive design using a survey instrument that was implemented to the selected Senior High School students in Region 11 and 12, Philippines.
 
Results and conclusion: The gathered data suggest that senior high school students have a strong grasp of climate change, particularly emphasizing the affective aspect of learning.
 
Implications of the research: The implication of this research is that senior high school students possess a strong understanding of climate change's affective aspects, suggesting the effectiveness of educational efforts in engaging students on this topic. Addressing the identified weak correlation between valuing and characterization could enhance climate change education by providing clearer guidance on integrating personal values with the development of individual philosophies, ultimately fostering comprehensive awareness and action among students.

Objective: To determine the effect of sweet potato leaves on the smooth production of breast milk and increase in baby weight at the Klari Health Center UPTD in 2023.
 
Method: Quasy Experiment with one group pretest-posttest design. The sample was 56 breastfeeding mothers 4 days after giving birth whose breast milk production was not smooth using a convenience sampling technique. Bivariate analysis uses paired simple t test.
 
Results: The results of univariate research on the smoothness of breast milk production before consuming sweet potato leaves (pretest) were mostly substandard at 57.1% with an average of 5.16. After consuming sweet potato leaves (posttest), most of them were 69.6% smooth with an average smooth breast milk production of 6.63. Most babies' weight before consuming sweet potato leaves (pretest) did not increase by 73.2%, afterward most of it increased by 60.7%. The results of bivariate research on the smoothness of breast milk production obtained a p value = 0.000 and an increase in the baby's weight obtained a p value = 0.000.
 
Theoritical framework: Non-smooth breast milk production can hinder the process of exclusive breastfeeding due to the mother's desire to take steps to stop breastfeeding and replace it with formula milk. There are many ways that can be done to facilitate breast milk, including through non-pharmacological measures such as consuming sweet potato leaves which can be consumed freshly or made into clear vegetables.
 
Conclusions and Suggestions: There is an effect of sweet potato leaves on the smooth production of breast milk and increasing the baby's weight. Nursing mothers are expected to consume sweet potato leaves regularly during breastfeeding in order to increase breast milk production so that breast milk production runs smoothly and the mother's baby gets exclusive breast milk.
