The effect of sandblasting surface treatment on shear bond strength between acrylic denture teeth and thermoplastic nylon denture base
Authors: Barus Ghea Primta , Nasution Hubban
Published: August 2024

Thermoplastic nylon has been introduced in dentistry as a material for denture bases since 1950’s. Thermoplastic nylon has become a popular alternative for denture fabrication, which provides better aesthetics and several advantages. Unfortunately, thermoplastic nylon has insufficient shear bond strength with acrylic resin, causing the acrylic denture teeth to often debond from the thermoplastic nylon denture base. Sandblasting is suggested can be used to increase shear bond strength between artificial teeth and denture bases. This study aims-to evaluate the effect of sandblasting surface treatment on shear bond strength between acrylic denture teeth and thermoplastic nylon denture base. Four groups with different aluminum oxide particle sizes (No treatment, 50 μm, 110 μm, 250 μm) were used in this study (n=8). A universal testing machine was used to test the specimens. The data were analyzed using the One-way ANOVA test. One-way ANOVA showed a statistically significant difference between groups (P < 0.001). There is an effect of sandblasting surface treatment on shear bond strength between acrylic denture teeth and thermoplastic nylon denture base. Sandblasting with 250 μm aluminum oxide showed the best result than another group. KEY WORDS: shear bond strength, sandblasting, acrylic denture teeth, thermoplastic nylon, denture base.

El curriculum universitario es coraza, fórceps, hipótesis, tesis, todo o partes, instrumento de transformación o conservación, caldo de méritos u oportunidad “proteica” de cada sociedad. 
El curriculum universitario, en cada caso es interpelado en cada momento histórico y en cada sitio geográfico, cultural y social. En tanto que proyecto social -siguiendo a la maestra Alicia de Alba-, es síntesis de elementos culturales diversos y contradictorios que conforman un proyecto político educativo donde se ponen en juego disputas, tensiones y pujas en función de intereses diversos, y que es resultado de procesos de negociación y acuerdos político institucionales. 
Situar su complejidad y su carácter histórico social, supone necesariamente también reconocer la ineludible responsabilidad respecto de su conformación, de quienes participamos activamente de los procesos de producción, distribución y circulación de conocimientos en la Universidad, fundamentalmente si entendemos a la educación superior como derecho de todos y todas. 
El momento histórico que atravesamos pone nuevamente en cuestión los sentidos de la universidad y por eso nos obliga a actualizar la reflexión en torno de los imperativos que entendemos deben asumirse desde las universidades públicas en nuestro país.

Penelitian ini membahas tentang arah mata angin pada rumah Bugis dan implikasinya terhadap Ilmu Falak di Desa Talungeng Kecamatan Barebbo Kabupaten Bone. Jenis Penelitian ini merupakan penelitian lapangan dengan menggunakan metode kualitatif. Adapun metode pengumpulan data, yaitu observasi, wawancara, dan dokumentasi. Hasil penelitian ini bahwa metodologi penentuan arah mata angin pada rumah Bugis di Desa Talungeng Kecamatan Barebbo Kabupaten Bone yakni dengan melihat posisi matahari, dengan melihat tempat terbenam ataupun terbitnya matahari. Adapun implikasi penggunaan arah mata angin pada rumah bugis terhadap Ilmu Falak di Desa Talungeng Kecamatan Barebbo Kabupaten Bone secara tidak langsung memiliki persamaan dengan Ilmu Falak sebagai suatu cabang ilmu yang berkaitan dengan benda-benda langit dalam menerapkan keilmuannya, salah satunya adalah penggunaan matahari sebagai metode yang digunakan oleh masyarakat Desa Talungeng dalam penentuan arah mata angin. Implikasi dari penelitian ini bahwa metodologi penentuan arah mata angin pada rumah Bugis menggunakan posisi terbit dan terbenamnya matahari sebagai salah satu metode dalam penentuan letak arah mata angin perlu untuk dilakukan penelitian lebih mendalam terkait dengan tingkat keakurasiannya dan juga penulis berharap agar tokoh agama ataupun mahasiswa Ilmu Falak itu sendiri dapat lebih memperhatikan dan melakukan sosialisasi terkait arah kiblat yang sebenarnya.

Authors: Rusdi Muh. , Purwanti Sri , Jamila
Published: August 2024

Pemanfaatan bahan baku lokal sumber protein hewani merupakan langkah yang tepat untuk saat ini, mengingat sumber protein masih di import dengan harga yang relatif mahal. Peneltian ini bertujuan untuk mengetahui efektivitas tepung maggot dengan level berbeda sebagai sumber protein terhadap performa ayam kampung super. Penelitian menggunakan rancangan acak lengkap dengan lima perlakuan dan empat ulangan, masing-masing ulangan terdiri dari 2 ekor ayam. Perlakuan penelitian yaitu P0 (Ransum tanpa penambahan tepung maggot BSF); P1 (Ransum dengan penambahan antibiotik gram negative (tanpa  penambahan tepung maggot); P2 (Tepung maggot 12% (4% protein kasar tepung ikan); P3 (tepung Maggot 16% (2% protein kasar tepung ikan) dan P4 (tepung Maggot 20% (0% protein kasar tepung ikan). Parameter yang diamati adalah performa ayam kampung super yang terdiri dari konsumsi pakan, pertambahan berat badan dan konversi pakan. Hasil penelitian menunjukkan penggunaan tepung maggot dengan level yang berbeda berpengaruh nyata (P<0,05) terhadap konsumsi ransum, pertambahan bobot badan dan konversi ransum. Berdasarkan analisis varians menunjukkan perlakuan P3 memiliki nilai konversi ransum paling rendah yaitu 1,58±0,01. Disimpulkan bahwa penambahan tepung maggot 16% dalam ransum dapat meningkatkan performa ayam kampung super.
Evaluasi Pertumbuhan dan Produksi Fodder Hidroponik Millet (Panicum milliaceum) dengan Perbedaan Intensitas Cahaya dan Umur Panen
Authors: Nur Hidayat Anisa Ayu Rini, , Harwanto  , Nur Hidayat
Published: August 2024

Hidroponic fodder is forage cultivation by using liquid medium which contain nutrients for growth. Plant growth is influenced by two factor, internal and external factors. Internal factors include genetic, growth hormon  and age. External factors include light intensity and plant growth medium. The aim of the study was to determine the effect of light intensity and harvest age on the growth and production of fodder millet (Panicum milliaceum). The study used white millet seeds with proso millet varieties, and hydroponic media. The study used a completely randomized design with a factorial pattern (2x3). The first factor is light intensity (I) 50% and I 100%. The second factor is harvest age (U) 6, 9, and 12 days. Each treatment combination was replicated 4 times. The density of millet seeds in the media was 0.15 gram/cm² and planted for 12 days using the Deep Water Culture (DWC) hydroponic system. The significance value was tested by Duncan Multiple Range Test (DMRT). The variables measured were leaf length, leaf amount, leaf width, root length, plant height, fresh production and dry matter production. The results showed that light intensity and harvest age had a significant effect (P<0.05) on fodder growth. The results show that light intensity can increase (P<0.05) fodder height from 4.51 cm (U6), 5.35 cm (U9) and 8.43 cm (U12) while at an intensity of 5.51 cm (I1) to I2 6.13 cm (I2) and fresh production from 9,48 kg/m2 (U6), 10,04 kg/m2 (U9) and 10,12 kg/m2 (U12) while the intensity of 10,07 kg/m2 (I1) becomes 9,69 kg/m2 (I2). The study concluded that light intensity 100% (13.933 lux) and harvest age 12 day could increase fodder millet growth.

Comparación de la eficiencia técnica del vermicomposteo respecto a los procesos más utilizados para la estabilización de lodos residuales en México
Authors: Domínguez Gavilán Verónica , Rodriguez Tapia Lilia , Morales Novelo Jorge Armando
Published: August 2024

A residual product of wastewater treatment plants (WTP) is sludge, which due to its pathogenicity and volume needs to be stabilized and utilized. In Mexico, even though the law requires it, few WTPs stabilize them. Hence, sludge is disposed in open pit dumps, drains and landfills, constituting a severe environmental problem. This research evaluates and compares the technical efficiency of sludge vermistabilization, with the most widely used methods in the country: aerobic and anaerobic. To obtain a viable option for designers, sludge from domestic treatment plants is considered. The evaluation is relevant as it guarantees to highlights the operability of stabilization methods. The analysis is carried out through the indicators obtained from the quality, quantity, and characteristics of the sludge. The method applied is the data enveloping analysis of Banker Chames and Cooper (DEA-BBC), based on the following indicators: the stabilization percentage, quality, retention time, energy expenditure – with and without energy recovery for the anaerobic process, the required area and the quantity production of stabilized sludge. The results suggest that vermicomposting is the most efficient technique when recording more efficient indicators. Only in two indicators proved to not be as efficient: retention time and required area. To determine the second and third recommended techniques, the standard deviations from the efficient point were estimated, anaerobic systems are identified as a second technique close to efficiency with a deviation of 0.70 and finally aerobic systems present a standard deviation of 0.74. This study therefore concludes that of the three methods considered to compare stabilized sludge, vermistabilization is the most efficient technique for domestic wastewater flows of less than 80L/s. In Mexico, 31% of existing WTP have similar flow rates and it is widely recommended to adopt this technique considered as a green technology.
Biorrestauración de un suelo contaminado con diésel mediante composteo con residuos de champiñón común (Agaricus bisporus) y cáscaras de plátano (Musa sp.)

Hydrocarbons are a source of soil contamination caused by spills and clandestine intakes. Among the friendliest restoration technologies is soil composting, a treatment considered as biostimulation, which works with cosustrates to develop microbial populations suitable for the degradation of the organic pollutants in question. This work evaluated the composting process of a diesel-contaminated soil (more than 21,000 mg TPH/kg soil, on a dry basis) using two different plant residues, as cosustrates: banana peels (Musa sp.) and common mushroom residues (Agaricus bisporus). Cells with oil/cosustrate mixture were built per duplicate at 1:0.5 ratio, which were given aeration twice a week and humidity was maintained at 30%. The process was carried out over eight weeks, with monitoring of the concentration of diesel and the microbial population. The diesel removal percentages at the end of the process were 79 and 95% for the soil/banana peel mixture and soil/mushroom residues, respectively. The largest removal was observed between the fourth and sixth weeks of the process for both cells, and the highest amount of microbial population was observed in the soil/banana peel mixture, although this was not the one with highest TPH removal. In addition, the microbial growth curve of the soil/mushroom residue mixture had a longer exponential growth phase than that of the banana soil/shell cell, so the latter is credited with the difference between removal percentages. In conclusion, soil composting using banana peel vegetable cosustrate or mushroom residues, can be considered as a feasible technology in the treatment of contaminated soils with high concentrations of diesel.
La vivienda con equidad
Authors: Aranda Cortés Laura Olivia
Published: August 2024

Women have been the main promoters of popular housing in Mexico and, in contrast, it is observed that in our country and in various parts of the world, the needs of women in terms of the design of architectural and urban spaces are made invisible since, predominantly, they are men of productive age and from public and private power, who conceive and build cities according to the patriarchal and capitalist hegemonic system. This work seeks to classify and analyze, from the gender perspective, various existing proposals on the architectural scale to identify those measures that help to reverse this problem, traversed by the variable of confinement caused by the COVID-19 pandemic. The theoretical framework is briefly identified with the concepts of: gender, gender perspective, discrimination and equity. Later they are related to the space and its design process, disaggregating its organizing principles such as: uses, forms, relationships, organization, proportion, among others. Here the analysis also has a political sense since this process is the modeller of the behaviors that seeks to solve the needs of a given system -in this case, the heteropatriarchal-, through the designation of the use of space, the specifications of the program architecture, the intentions and the formal concept, the distribution of space, its operation and the materialization of architecture. Based on this analysis and its confrontation with the statistical reality of Mexico, it is observed that the space constructed as it is currently in our country, discriminates against women and the people under our care.
Valor patrimonial de los paseos históricos más emblemáticos de la Ciudad de México
Authors: Pérez Bertruy Ramona Isabel
Published: August 2024

This essay introduces historical, artistic, cultural, and environmental aspects that are key to understanding the heritage features of Mexico City’s most emblematic historical promenades, namely, Bosque de Chapultepec (Chapultepec Forest), Alameda Central, and Paseo de la Reforma. In this regard, it is worth mentioning that several authors have written about the history of these public recreational spaces; nevertheless, to date, no publication intends to reflect on the cultural values of the most representative promenades of the national capital. I am interested in highlighting this topic as there is no awareness in society about their cultural importance, nor has the academy tried to think in this line. In this vein, I want to point out in this work some tangible and intangible values, in order to emphasize their importance as cultural assets of the nation.
Criterios para la integración de paisajes culturales de áreas en recuperación
Authors: Blanco Gómez Alan Alberto , Mariscal Torres Nayeli , Puebla López Susana , Revueltas Valle Emilio
Published: August 2024

La Ciudad de México es el resultado de la evolución y el crecimiento acelerado de la población en el área urbana y las áreas verdes. Es importante recordar, la mayoría de los asentamientos humanos que se dieron, tienen raíces históricas. Ejemplo de ello son los numerosos poblados rurales y barrios prehispánicos que actualmente conservan desde el virreinato su nombre original, aunado a otros de origen religioso y la conservación de la traza urbana original (calzadas prehispánicas y trazas reticulares en la época del virreinato). Todas estas zonas históricas o patrimoniales se caracterizan por contener un rico legado cultural - natural, arquitectónico - urbanístico, social y de comercio popular tradicional. Las Áreas de Conservación Patrimonial (A.C.P.) son herramientas para proteger, mantener y potenciar todos aquellos bienes muebles e inmuebles, por destino, elementos aislados, mobiliario urbano, obras de infraestructura, imagen urbana, paisajes culturales y espacios públicos como parques urbanos, plazas y jardines entre otros; son aquellos elementos y espacios que, sin estar formalmente catalogados merecen tutela en materia de conservación y consolidación y, en general, todo aquello que corresponda al acervo histórico o que resulte propio de sus constantes culturales, naturales y de sus tradiciones. Sin embargo, no son instrumentos suficientes para contener la acelerada transformación urbana, económica, social, cultural y ambiental propia de la evolución de las ciudades modernas en el siglo XX. El área de estudio de la Segunda Sección del Bosque de Chapultepec (periodo del análisis noviembre 2020) El reto para el planificador consiste en identificar, resaltar y conservar el valor del paisaje natural e integrarlo como área en recuperación, para poderlo transformar en un paisaje cultural en donde se subrayen los componentes sensoriales y simbólicos que ofrecen mayor intensidad a la percepción del usuario, integrando a los habitantes con la finalidad de sensibilizarlo y educarlo, forjando así identidad en la riqueza paisajística.
Vivienda social y COVID-19: el fin de una era funcionalista y capacitista
Authors: Solano Meneses Eska Elena
Published: August 2024

Social housing became a protagonist scenario after the pandemic was declared in March 2020. The strict confinement to which the population was subjected to contain the spread of contagions, forced the realization of almost all activities inside the housing, questioning the functionalist and capacitist theories, which prevail in the design and that obey economic criteria derived from mass production. The methodology includes a revision of social housing from new categories, neither functionalist nor capacitist. The new spatial needs to perform home office or participate in virtual classes, also evidence the lack of flexibility in the spaces proposed by functionalist architecture, which presented an idea of spaces with defined and specialized purposes in an arbitrary and rigid way. The new spatial dimension also generates a demand for wider spaces to allow for social distancing, since it is now common knowledge that COVID-19 spreads especially when people are in close contact (about 1.5 meters approximately) for a prolonged period. Likewise, the new valuation, for health reasons, of open spaces for: a) coexistence with less risk of contagion, b) sunlight and to encourage the generation of vitamin D with the intention of strengthening the defenses, and c) exercise, since physical activity strengthens the immune system, force us to rethink the design of housing, which in the past only looked at the spaces under a utilitarian approach. This work analyzes each problem exposed in social housing, the results of which leave evidence of the deficiencies of housing design in the face of paradigms centered on functionalism and capacitism. It is concluded that it is necessary to reconsider new paradigms, associated with the idea of accessibility, inclusion, health, dignity and quality of life.
Does working capital management influence firm competitiveness?

Published: August 2024

Working Capital Management (hereafter WCM) is the strategic tool that helps a company navigate through challenging economic growth, and influence its competitive performance. Thus, this study examines the impact of WCM on the competitiveness of firms operating in the non-financial sectors in Pakistan. We use the Generalized Method of Moments (GMM) technique to ensure the robustness of our results. The study findings reveal that both a large net trade cycle and surplus working capital have a substantial negative impact on firms’ competitiveness within their respective industries. These results suggest that companies should streamline their investments in working capital accounts and concentrate more resources on long-term projects that maximize value to improve their competitiveness compared to other companies. Therefore, firms that are effectively managing their short-term financial affairs are experiencing much better performance in all aspects of firm performance. The research findings highlight the urgent need for governmental initiatives designed to improve WCM practices in these industries. It is imperative for the management of  companies with excess net working capital to maximize their working capital efficiency, aligning it with industry standards to enhance competitiveness. Moreover, policymakers should prioritize easing access to financial alternatives that allow enterprises to maintain an efficient working capital structure without relying on excessive measures. Furthermore, policymakers should be cautious when determining minimum cash balance requirements in a cash-strapped economy where external financing is relatively more expensive than in other regional economies.

Published: August 2024

The study examines the impact of COVID-19 on the economies of Gulf Corporation Council (GCC) member states. The event study methodology was used to analyze Cumulative Abnormal Return (CAR) of GCC member states’ stock indexes: Kuwait Stock Exchange Index (KSE), Dubai Financial Market Index (DFM), Saudi Arabia Tadawul Index (TASI), Qatar Exchange Index (QE), Bahrain All Share Index (BHB), Oman’s Muscat Stock Exchange Index (MSM), Abu Dhabi Stock Exchange Index (ADX) while the S&P GCC Composite Index was used as a reference. Data obtained from 28 July 2019 to 27 July 2020, and 1 March 2020, designated as the event day, abnormal returns (AR) and cumulative average abnormal returns (CAARs) were examined across various time intervals. The findings reveal significant market reactions to the pandemic, characterized by fluctuations in abnormal returns and CAARs. Statistically significant abnormal returns and CAARs during certain time periods underscore the dynamic nature of market responses to the COVID-19 event. These results provide valuable insights for policymakers and market participants seeking to understand and navigate the economic implications of the pandemic on GCC economies.

Бронхиолит (по результатам компьютерной томографии легких) наблюдается у 30% больных РА, является частым внесуставным (системным) признаком и распространенным видом патологии дыхательной системы при РА. Клинические симптомы бронхиолита выявляются только у половины больных РА с КТ-признаками бронхиолита, т.е. при РА определяется субклинический (малосимптомный) вариант ревматоидного бронхиолита. Факторами риска ревматоидного бронхиолита являются курение, мужской пол больного, молодой возраст дебюта болезни, высокие уровни DAS 28, РФ и АЦЦП.

Bronchiolite (according to the results of computed tomography of the lungs) is observed in 30% of patients with RA, is a frequent extra -intake (systemic) sign and a common type of pathology of the respiratory system with RA. The clinical symptoms of bronchiolite are detected only in half of the patients with CT signs of bronchiolite, i.e. With the RA, a subclinical (low sympomic) variant of rheumatoid bronchiolite is determined. The risk factors of rheumatoid bronchiolite are smoking, the male sex of the patient, the young age of the debut of the disease, high levels of DAS 28, the RF and the ACCP.

Optimizing the safety profile of methotrexate in rheumatoid arthritis: what does the real clinical practice show?
Authors: Машкунова О.В.
Published: August 2024

Оптимизация применения метотрексата при ревматоидном артрите достигается путем различных путей введения, одним из которых является подкожный путь, доказавший свою эффективность благодаря высокой биодоступности, быстрой скорости наступления эффекта, меньшей гепатотоксичностью и диспепсическими расстройствами. При этом в реальной клинической практике не всегда учитывается разница в биодоступности перорального и подкожного метотрексата, поэтому часто происходит передозировка методжекта из-за больших доз, приводящих необоснованно к отменам препарата, переключении на другой синтетический базисный препарат и раннему назначению ГИБТ. В статье приведены данные литературы о современных исследованиях по различиям в биодоступности разных путей введения метотрексата и результаты собственного исследования по оптимизации доз и улучшению профиля безопасности при подкожном введении метотрексата при деэскалации дозы подкожной формы метотрексата (методжекта) в шаг 2,5 мг, с 15 мг до 12,5 мг.

Optimization of the use of methotrexate in rheumatoid arthritis is achieved through various routes of administration, one of which is the subcutaneous route, which has proven effective due to its high bioavailability, rapid onset of effect, less hepatotoxicity, and dyspeptic disorders. At the same time, in real clinical practice, the difference in the bioavailability of oral and subcutaneous methotrexate is not always taken into account, therefore, an overdose of the metoject often occurs due to large doses, leading to unreasonable drug withdrawals, switching to another synthetic basic drug, and early prescription of GIBT. The article presents literature data on modern studies on differences in the bioavailability of different routes of administration of methotrexate and the results of our own study on optimizing doses and improving the safety profile with subcutaneous administration of methotrexate with de-escalation of the dose of the subcutaneous form of methotrexate (metoject) in steps of 2.5 mg., from 15 mg. up to 12.5 mg.

Optimal spur dike orientation for scour mitigation under downward seepage conditions
Authors: Patel Harish K. , Kumar Bimlesh
Published: August 2024

River bank protection is vital in hydraulic river engineering to preserve natural rivers, lands, and critical constructions such as bridges. Spur dikes are erosion-protective structures that protrude outward from the river bank in different orientations to deflect the flow away from the riverbank. The present experimental study provides insight into the temporal variation in bed morphology and scours around rectangular-shaped spur dikes with different orientations, such as 60º, 90º, and 120º. Also, maximum scour depth (MSD) is developed compared to the condition when downward seepage is applied. The experiments examined the suitability of various spur dike orientation configurations and the scour development over time, specifically at intervals of 2, 12, and 24 hours, and compared with 24 hours (Seepage). Results showed that the orientation angle of 90º generated the highest scour depth, while the least scour depth was found with an orientation angle of 120º. The downward seepage intensifies the motion of sediment particles and leads to an escalated particle detachment, resulting in deeper scour depressions. The development of scour depth is initiated from the spur dike tip and reaches its maximum there. The deposition of sand particles shifted downstream, and a dune-like structure formed near the second spur dike.
