One of the methods to increase the oil recovery is by signifcantly increase the capillary number. This can be achieved by reducing the interfacial tension (IFT) between the oil and the water in the reservoir to an ultra-low value. There are many studies conducted that proved the ability of Winsor Type-III microemulsion to reduce the IFT to an ultra-low value. Winsor Type-III microemulsion can be created by mixing surfactant, cosurfactant or cosolvent, brine, and oil. However, there has not been any research related to microemulsion creation conducted on alpha olefn sulfonate, AOS and alkyl polyglucoside, and, APG surfactant mixture. Commonly, alcohol as a cosolvent will be added to the surfactant system to enhance the surfactant ability in creating Winsor Type-III microemulsion, but in this project, alcohol will be replaced with an environmental friendly nonionic surfactant, lauryl glucoside. In this project, the phase behavior study of a novel ‘green’ surfactant mixture was conducted to evaluate the potential of the surfactant in creating Winsor-Type III microemulsion and determine the optimum formulations to create a stable Winsor Type-III microemulsion. The phase behavior studies were conducted in three stages which are the optimization of salinity, surfactant concentration, and cosurfactant concentration. Phase diagrams were constructed to properly analyze the phase behavior of the components in a wide range of decane volumes. From the phase behavior studies conducted, it can be concluded that the optimum formulation is 3 wt% salinity, 1 wt% AOS, and 3 wt% lauryl glucoside. Lauryl glucoside addition in the mixture could alter the HLB value of the surfactant mixture hence increasing its potential in creating Winsor Type-III microemulsion.

This study investigated the characteristics of non-asbestos brake pads in hybrid-polymer matrix composites. Steel slag, silica, calcium tri-oxocarbonate IV and graphite in varied weight percentages were added to the molten phenolic resin to develop the composites. The microstructural examination was carried out on the samples using a scanning electron microscope. The composites’ physical, mechanical, chemical and thermal properties were evaluated at room temperature. The results obtained were compared with a commercial brake pad. The microstructure revealed a fair distribution of the particles in the resin matrix. The control sample exhibited the lowest wear rate of 0.6 and 0.8 g/Nm at loads of 7.5 and 10 N, respectively. This implies better wear resistance characteristics than the other samples. The samples exhibited appreciably high coefcient of friction of 0.410, 0.413, 0.440 and 0.40 for samples A, B, C and D, respectively, which is within the acceptable limit (0.3 – 0.6) for the brake pad. Sample A exhibited the highest compressive strength of 7.78 MPa, which is followed by samples C (3.04 MPa) and D (1.52 MPa). The results indicate that the compressibility of samples decreased with increasing steel slag and phenolic resin content. Sample D, which exhibited a lower wear rate (1 g/Nm) and coefcient of friction (0.40) than samples A, B, and C, exhibited the lowest water absorption rate. The specifc gravity of the samples produced ranges between 2.45 and 2.61, which compare well with the commercial brake pad. Sample A was produced with the lowest proportion of steel slag and phenolic resin and exhibited the lowest acetone extraction. Samples A and B exhibited better thermal stability – an indication of good resistance to thermal decomposition. The thermal conductivity of the samples ranges between 134 and 193 W/mK, which is quite high compared to the standard and decreased signifcantly with an increase in temperature.
Keywords: Hybrid polymer composites, steel slag, wear rate, coefcient of friction, compressive strength, thermal stability.

Published: February 2024

A 25-year-old female existing with mild pain and discomfort during mastication in her right posterior maxillary tooth. On clinical examination, the maxillary first molar tooth was restored with a composite filling. The tooth did not respond to heat or cold test, and it was tender to percussion. Radiograph examination revealed poor obturation of the canals and the	periodontal ligament space was broad but there was no definitive periapical radiolucency. Conservative non-surgical root canal treatment was performed; a total of seven root canals were detected and they were obturated by using the calcium-based sealer. Radiograph with RVG and CBCT also confirmed that all seven canals were properly obturated. Twelve months later, there were no clinical or radiographic changes of the treated tooth. These findings suggested that careful examination of the floor of the pulp chamber with RVG and CBCT help to find extra root canals.

La Admisibilidad del laudo arbitral electrónico en Nicaragua
Authors: Rodriguez Palacios Tania del Socorro 
Published: February 2024

El comercio electrónico es importante y podría decirse inevitable, con la aparición del internet el mundo cambió, de igual manera, los medios para resolver disputas. El arbitraje, es el mecanismo de resolución alterna de conflictos con mayor uso en el comercio internacional, debido a las ventajas que este presenta, por esta razón, se necesita regular el arbitraje comercial a través del medio electrónico. El objeto de este artículo es el análisis de la admisibilidad del laudo electrónico en Nicaragua de conformidad a su ordenamiento jurídico. La presente investigación es teórica con enfoque cualitativo, el método a utilizar es analítico-sintético y el derecho comparado; para analizar cada uno de sus componentes y posteriormente integrarlo en posibles soluciones para la admisibilidad del laudo arbitral electrónico, en la legislación nicaragüense. Asimismo, se realiza una comparación de la legislación nacional con otros sistemas jurídicos. El análisis valora que la naturaleza jurídica del arbitraje y su laudo no se ven alteradas, solo que se encuentra desarrollado por un medio electrónico, puesto que la intelección genética del arbitraje no cambia; en cuanto a la validez y eficacia el laudo cuenta con las mismas formalidades de uno emanado de un arbitraje offline, solo que se encuentra contenido en formato digital. El marco del ordenamiento jurídico de Nicaragua no contempla el principio de equivalencia funcional lo que hace difícil llevarse a cabo. Por ende, necesita actualizar la regulación de los mecanismos de resolución a las disputas que se puedan generar entre los sujetos de comercio electrónico.
The continuity of the vocal and performing heritage of the multi-genre song culture of the Kuban Cossacks
Authors: Mironova Anastasiya Vladimirovna 
Published: February 2024

The object of the study is the continuous preservation of the multi-genre Cossack folk song, which represents a key purpose in the implementation of the preservation of the traditional mentality at the present stage. The subject of this work is the immanent complexes of traditional song culture in the folklore heritage. The purpose of this study is to structure the issue of the cultural interrelation of the ethnic canvas of the Kuban Cossack folk songs, in the originality of the genesis of the vocal and performing specifics of modern creativity. When discovering the fundamental foundations of the vocal performance of the Cossack song, special attention is paid to the study of the folklore primary sources of the Kuban folklorists, V.G.Zakharchenko, A.D.Bigdai, G.M.Kontsevich. Along with this, an expert assessment of the characteristics of the Kuban Cossack folk song according to the genre classification component is an important feature of the performance of vocal samples today. The theoretical basis is in an analytical approach to the peculiarities of the performance of a local source from the point of view of substantiating the scientific nature of the subject under consideration according to the functionally oriented elements of the report: traditions, traditional manner of performance, interpretation of the text, song melody. Methodological basis: components of the study of the local singing tradition, modernization of folklore song documents, the method of consistency-the genre diversity of Cossack performance. The author's approach to the correlation of musical sources as methodological characteristics of the Kuban Cossack singing traditions has been developed. We test the proposed system when working with archival documents, in the diagnosis of song samples recorded from informants. The key aspect is the musicological analysis of the musical collections of Kuban Cossack folk songs from the point of view of the continuously developing, multifaceted changing performing skills of the soloist and choir. The author takes into account the introduced model of performing Cossack songs since the resettlement of the Black Sea Cossacks, who brought the baggage of multi-genre sources and eventually introduced the Kuban folk singing art. The scientific novelty of the research lies in the author's analytical systematization of authentic song compositions recorded by folklorists, in the analysis of multi-genre Kuban Cossack sources (selectively) for further active performance on stage. The specific directions of performance according to characteristic song genres are determined: historical, military, everyday, marching, lyrical, wedding, ceremonial, round dance, comic. The reproduced orientation of the nature of the continuous preservation of folklore sources in the revised performance interpretation of Cossack vocal works gives rise to significant broadcasting opportunities today.
Phonology and Attrition: Sociolinguistics of (Ukrainian) Sound Perception
Authors: Chybras Yurii 
Published: February 2024

Abstract
This article’s research question is to explore the role of sociolinguistic factors in combination with phonology-driven perception. The preliminary hypothesis is that sociolinguistic factors like bilingualism and L2 interference (attrition, as in de Leeuw, E., Chang, C. 2023) may have a decisive role in the process of sound perception and is based on the example of English-Czech/Slovak and English-Ukrainian loanword adaptation cases involving the phonemes /ɡ/, /h/, /ɦ/, and /x/: Czech and Slovak speakers adapt [h] as [ɦ] while Ukrainian speakers tend to adapt the same phoneme as [x] despite having /ɦ/ in their phonological inventory. This tendency seems to correlate with phonological attrition (L2 interference of Russian) and has been a topic of active discussions, especially so since the 2022 full-scale Russian invasion of Ukraine.
The research method is based on a questionnaire with audio samples containing both already existing and made-up proper names and words. Half of the test vocabulary units are designed to contain the chosen sounds, the rest of the units are represented by established, already existing, names, and units that do not contain the chosen sounds to provide a cover for the experiment. The respondents are asked to listen to the audio samples and write down the units as they hear them using Ukrainian alphabet. The respondents were provided with a fake description, and a fake goal of the experiment to exclude possible bias.

Aim: To evaluate the behavior of soybean varieties recently introduced in germplasm of National Pulses Program of National Institute for Agricultural Study and Research.
Study Design: The study was conducted using a randomized complete block design (RCBD) with six treatments replicated three times.
Place and Duration of the Study: The experiment was carried out at the Lieutenant-Colonel EBEYA Military Camp, precisely in the POUDRIERE site in LOMA district from April 14 to June 17, 2023.
Methodology: The study was conducted with six soybean varieties replicated three times. Data collected concerned percentage of seedlings emerged, vegetative development and production parameters.
Results: The emerged plants rate varies from 82.6 to 90%, collar diameter from 4.3 to 6.4mm, and plant height from 27.9 to 51.3 cm. The leaflet number per plant varies from 18.3 to 32, while their length and width varied from 6 to 9.4cm, and from 10.5 to 17.7cm, respectively. On each plant, the number of branches bearing pods varied from 3.6 to 5. The number of pods and seed per plant varied from 18 to 37, and from 34.3 to 68, respectively. Overall, soybean varieties flowered on 34.4 to 68 DAS. The 100-seed weight varied from 8 to 15.3g, and yield obtained from 572.9 to 2,203kg/ha.
Conclusion: Overall, the results of this study indicate that vegetative development and production parameters vary among varieties. This variability in behavior results from the interactions between intrinsic properties of each soybean variety and agroenvironmental conditions of experimental field. The yields obtained were lower than the global average. However, variety TGM 0169 considered late, had high emerged plants rate (90%), and yielded more than 2t/ha, which is far higher than the average recorded in the majority of Sub-Saharan African countries. Ultimately, TGM 0162 appeared as elite variety whatever parameter considered.
The Effect of Gate‐Dielectric Surface Energy on Pentacene Morphology and Organic Field‐Effect Transistor Characteristics
Authors: Yang S. Y. , Shin K. , Park C. E. 
Published: September 2005

AbstractThe effects of the surface energy of polymer gate dielectrics on pentacene morphology and the electrical properties of pentacene field‐effect transistors (FETs) are reported, using surface‐energy‐controllable poly(imide‐siloxane)s as gate‐dielectric layers. The surface energy of gate dielectrics strongly influences the pentacene film morphology and growth mode, producing Stranski–Krastanov growth with large and dendritic grains at high surface energy and three‐dimensional island growth with small grains at low surface energy. In spite of the small grain size (≈ 300 nm) and decreased ordering of pentacene molecules vertical to the gate dielectric with low surface energy, the mobility of FETs with a low‐surface‐energy gate dielectric is larger by a factor of about five, compared to their high‐surface‐energy counterparts. In pentacene growth on the low‐surface‐energy gate dielectric, interconnection between grains is observed and gradual lateral growth of grains causes the vacant space between grains to be filled. Hence, the higher mobility of the FETs with low‐surface‐energy gate dielectrics can be achieved by interconnection and tight packing between pentacene grains. On the other hand, the high‐surface‐energy dielectric forms the first pentacene layer with some voids and then successive, incomplete layers over the first, which can limit the transport of charge carriers and cause lower carrier mobility, in spite of the formation of large grains (≈ 1.3 μm) in a thicker pentacene film.
Two‐Dimensionally Ordered Copper Grid Patterns Prepared via Electroless Deposition Using a Colloidal‐Crystal Film as the Template
Authors: Cong H. L. , Cao W. X. 
Published: September 2005

AbstractTwo‐dimensionally ordered copper grid patterns with different pore sizes and thickness have been fabricated via electroless copper deposition using a colloidal‐crystal film as the template. The pore size of the grid can be adjusted by altering the deposition time. The copper films, with thicknesses of ≈ 100–130 nm and pore sizes of ≈ 100 nm, are flexible and can be peeled off a silicon wafer and rolled up into a reel. Three‐dimensionally ordered porous copper materials have also been prepared using a similar method.
