Published: March 2024

The impact of temperature and air velocity on the drying of pituca (Colocasia esculenta) sheets was investigated. The samples, 1.5 mm thick, were subjected to a tray dryer at three temperatures (45, 50 and 55 °C) and three air velocities (2.5; 3.0 and 3.5 m/s). After grinding the dried sheets, the physicochemical, microbiological and sensory properties of the pituca flour were analyzed. The findings indicated that the drying curves conformed to the exponential model proposed by Herdenson and Pabis, with a coefficient of determination greater than 96%. The optimum treatment, T9, used a temperature of 55 °C and a speed of 3.5 m/s. It showed a critical moisture of 1.53 g/g dry pituca, an equilibrium moisture of 0.9 g/g dry pituca, and a critical time of 20 minutes. Values for ash, moisture, mesophilic aerobes, molds and yeasts were recorded at 3.37%, 8.04%, 9.90x103 CFU/g, and 2.40x103 CFU/g respectively, with absence of Escherichia coli. At higher temperatures and air velocities, the best sensory ratings were obtained. In conclusion, these parameters result in superior quality for pituca flour in kinetic, physicochemical and sensory terms.

The current food industry drives interest in foods that not only satisfy basic needs, but also promote health. In this context, yacon, with its fructooligosaccharides (FOS)-rich syrup, emerges as a valuable plant source for improving the properties of bread. This study evaluated the effects of FOS addition from yacon on the physicochemical and sensory characteristics of bread. A traditional methodology involving bread making with different concentrations of the syrup was employed. The results revealed that the treatments with 0.5% and 1.5% yacon syrup excelled in bulk density, crumb cell shape and crumb appearance. In the sensory evaluation, the 0% and 0.5% treatments scored best in crust colour, texture and flavour. In conclusion, the addition of FOS to bread was shown to significantly improve its physicochemical and sensory characteristics: the addition of 1.5% and 0.5% improved bread density and appearance, while the 0% and 0.5% treatments obtained better sensory ratings.

Published: March 2024

En este estudio, se llevó a cabo una revisión sistemática de la literatura que aborda la relación entre el gasto público y la reducción de la pobreza, utilizando técnicas de minería de texto. Se examinaron un total de 24 artículos publicados entre 2015 y 2021, obtenidos de diversos buscadores académicos. Los métodos de análisis más frecuentemente empleados para investigar esta relación incluyeron modelos de regresión lineal, logística y mínimos cuadrados. Se destaca la importancia de medir la pobreza en cualquier contexto, ya que esto permite identificar los grupos más vulnerables mediante un diagnóstico de las carencias sociales que afectan a la población. A través de este estudio, se puede comprender mejor el impacto de las políticas públicas implementadas en áreas con altos índices de pobreza. Así, la identificación de la relación entre el gasto público y la reducción de la pobreza adquiere relevancia en la toma de decisiones por parte de quienes tienen la responsabilidad de asignar la inversión pública. Sin embargo, la literatura revisada sugiere que simplemente aumentar el gasto público no es suficiente para resolver los problemas de pobreza; si bien es un factor necesario, otras estrategias pueden ser igualmente importantes para lograr una reducción significativa de la pobreza.

A review of Pharmaceuticals removal from water resources using magnetic iron-based nanomaterials
Authors: Nyakairu George William Atwoki , Shehu Zaccheus
Published: March 2024

The presence of pharmaceuticals in water resources is a growing concern worldwide due to their potential health impacts on aquatic life and humans. Therefore, there is a need to develop effective and sustainable technologies for removing these contaminants from water and wastewater. Magnetic nanomaterials have emerged as promising materials for this purpose due to their fast kinetics, easy magnetic separation, and reuse. This review is important as it highlights the significance of developing sustainable technologies using magnetic iron-based nanomaterials for removing pharmaceutical contaminants from water resources. This review investigated the application of magnetic nanomaterials for removing pharmaceuticals from water resources through adsorption and advanced oxidation processes. Here, the synthesis and characterization of magnetic nanomaterials and analytical detection techniques were evaluated. The review findings indicate that magnetic nanomaterials effectively removed pharmaceuticals from water through adsorption and advanced oxidation processes. More importantly, the removal processes remained effective for many cycles. However, only 22% of the studies demonstrated the application of magnetic nanomaterials on real water samples, as 78% stopped at experiments using distilled water in the laboratory. Further research on multi-component systems and real water samples is necessary to fully evaluate the potential of magnetic nanomaterials for pharmaceutical removal from water resources.
Solar desalination with charcoal briquettes from plants as an additional absorption sorbent
Authors: Jafri Muhamad , Tarigan Ben , Adoe Dominggus
Published: March 2024

Water is the most abundant substance on Earth, but only 2.5% can be used for drinking and farming; the rest is seawater containing much salt. Solar desalination is a great tool to solve this problem for small families and remote areas. However, the disadvantage of using solar power is still the low productivity of distillate because it depends on the season, region, and intensity of solar radiation. Solar radiation heat absorbing and storing materials are a favorable solution in increasing evaporation rate, efficiency, and total distillate. Many have been developed to date, but these materials require more expenditure to be used as radiation heat sinks and stores. Charcoal derived from wood has high thermal energy absorption and porosity. Four desalination devices were used, namely using an additional absorber made from Kapok wood (Ceiba pentandra) coded CP_60, Gamal wood (Gliricidia sepium) coded GS_60, Kusambi wood (Schleichera oleosa) coded SO_60, and without additional absorber as a comparison. All desalination devices have the same shape and size, simple, with an area of 0.09 m2 each. Before the additional absorber base material is used, drying, charring, grinding, meshing, pressing, and briquetting are carried out. The test results show that the additional absorber of natural materials affects the evaporation rate, desalination efficiency, and total distillate water. The distillation device using Gamal wood (Gliricidia sepium) additional absorber material, coded GS_60, provides maximum performance such as distillate water yield every 30 minutes and total distillate 124 ml/0.09 m2, 28.19% efficiency, and evaporation rate.

O objetivo do estudo foi avaliar o desempenho de juntas (taliscas) coladas de diferentes espécies com quatro adesivos. Com o conhecimento prévio das propriedades mecânicas das madeiras, este trabalho objetivou a realização de uma avaliação do comportamento das juntas de cola da madeira calabura (Muntingia calabura), comparando-as com taliscas coladas de madeiras das espécies angico vermelho (Anadenanthera colubrina), Eucalyptus sp., mogno africano (Khaya ivorensis) e Pinus sp. Toras de calabura foram transformadas em tábuas, e as tábuas desdobradas em amostras (taliscas) de 0,6 × 2,5 × 44,0 cm3 (espessura × largura × comprimento) e climatizadas até atingirem a umidade relativa de equilíbrio. As taliscas das demais espécies já estavam disponíveis no laboratório e nas mesmas dimensões. Para a colagem utilizou-se a gramatura de 300 g.m-2 para todos os adesivos ureia-formaldeído (UF), melamina-formaldeído (MF), tanino-ureia formaldeído (TUF) e poliacetato de vinila (PVA). As juntas coladas foram prensadas a frio em uma prensa hidráulica manual. Em relação a eficiência da colagem, observou-se que houve uma adesão satisfatória entre a madeira e os diferentes adesivos colados. Os valores médios de resistência ao cisalhamento na linha de cola estiveram abaixo do que é recomendado para uso comercial. A porcentagem de falha ficou acima dos 60% recomendados, reforçando os dados observados para resistência que indicaram a qualidade satisfatórias das juntas. A madeira de eucalipto colada com MUF apresentou a maior resistência ao cisalhamento por compressão na linha de cola (5,19 MPa). A espécie com a menor resistência ao cisalhamento na interação com os adesivos foi a calabura, com o valor médio mínimo de 1,40 MPa ao ser colada com UF, e tal comportamento pode ser atribuído aos elementos anatômicos.

Published: March 2024

To improve the safety of nuclear power plants, a modern NPP such as Advance Pressurize Water Reactor (APWR) is equipped with a safety feature called PCCS (Passive Containment Cooling System), where naturally circulating air cools the outer surface of the containment which is used to remove decay heat released inside the containment vessel. The decay heat from the reactor core will be transferred out through the conduction mechanism and the natural convection mechanism on the outer surface of the containment vessel. Then, the hot air that forms in the gap between the containment and its baffles will rose through the chimney located at the top of the concrete building and cold air will enter through the inlet to create a natural circulation cycle. To obtain the effectiveness of the use of baffles, as a comparison, it is necessary to analyze the natural convection heat transfer on the outer surface of a containment vessel that is not equipped with a baffle. In this research, CFD analysis of natural convection on the outer surface of the containment of APWR reactor model has been done. Based on the model developed, the analysis was done to get temperature and convection heat transfer coefficient in the air flow on the containment surface. Heat flux in the containment surface varied from 500 W/m2 to 2.000 W/m2 with an increase of 500 W/m2 intervals. Based on the analysis results, the correlation equations are also proposed in this paper, namely the correlation of natural convection heat transfer for laminar regime on a vertical cylindrical with the heat flux constant in the form Nuq = a(Raq)b.

Carbon Fiber Reinforced Polymer (CFRP) considered as unique material as it is proven have the best mechanical properties which can be used as a wrapping. This composite material will be evaluated as a wrapping material using SolidWork version 2021 software. Elbow has been chosen as component to be wrapped as it is one of the most critical parts in a pipeline system. Thus, this research focuses on 90-degree butt welded elbows. The study evaluated different lamination and thickness of CFRP as a wrapping framework for elbows. Static analysis also was stimulated to analyze the stress and strain exerted on elbows at extrados location. Based on static analysis simulation from SolidWork software, lamination orientation of (0º) with 6 layers exhibit lowest stress for all the pressure tested ranging from 0.86MPa to 19.65MPa for 90-degree defected elbow at extrados location. Besides, comparing CFRP and Glass Fibre Reinforced Polymer (GFRP), CFRP showed it able to reduce stress compared to GFRP when tested on the same defected elbow. Lastly, the flow simulation in CFD showed there were no leakages especially on defected area and no sudden changes on pressure, velocity, and temperature.

Published: March 2024

Hybrid fiber reinforcements can incorporate a wider array of qualities than single fiber reinforcement. Instead of synthetic fibers, applying plant and animal-based organic materials as reinforcement in polymer matrix offers certain benefits, such as low price, greater availability, and better biodegradability. In the present study, water hyacinth fiber and sheep wool fiber reinforced polypropylene hybrid composites were fabricated at three different (5, 10, and 15 wt.%) fiber loading. The effect of fiber loading on thermo-mechanical, structural, and biodegradability properties was subsequently investigated. The manufacturing process of the composite material was carried out with utmost consideration for biodegradability, since polypropylene, the primary constituent, is not inherently biodegradable. The insertion of fibers into the polypropylene matrix showed variance in properties of different aspects. The tensile strength of the composites displayed a downward trajectory (from 25 to 10 MPa) with a 15% increase in fiber loading due to voids, and fiber dispersion, while impact strength exhibited an opposite trend (from 25 to 32 J/m). Except for hardness, all the mechanical properties degraded slightly after the employment of the reinforcement. Fourier transform infrared spectroscopic analysis revealed the movement of typical peaks and the appearance of new peaks demonstrating the bonding between the fiber and the matrix. Thermogravimetric analysis showed that the thermal degradation temperature of the composites improved at maximum fiber loading. On the other hand, the goal of achieving biodegradability has been succeeded by the implementation of a combination of plant and animal-based fibers as biodegradability of the manufactured composites thrives with increasing fiber content for the presence of cellulosic bonds, as evident from the FTIR spectrum. Even though some properties of the hybrid composite declined slightly with increasing fiber loading, the other characteristics, including service temperature and biodegradability experienced a prospective advancement. Hence, the 15% fiber-loaded composite was found to be a potential candidate in terms of slightly high temperature and environment-friendly applications.

Bu sistem içindeki en önemli ögelerden biri sözcüklerdir. Sözcükler, göstergelerden oluşan sistemleri inceleyen gösterge biliminin de temel kavramlarındandır. Öncelikli amacı anlaşılmak olan iletişim şekillerinde yalın, kısa ifadelerin seçildiği ve beden dilinin de sıklıkla iletişime eşlik ettiği görülmektedir. Ağızlar da insanların kısa, sade anlatımlarla ve bazen de beden dili aracılığı ile kendilerini ifade ettikleri dillerdir. Bu nedenle ağızlarda tercih edilen göstergeler büyük bir çağrışım gücüne sahiptir. Bu çalışmada Erzincan ağzındaki göstergeler, nitelikleri bağlamında Kloepfer’in tasnifi esas alınarak incelenmiştir.

In every construction and renovation project, there is often waste that is rarely reused. The utilization of ceramic waste as a coarse aggregate in concrete can be an interesting alternative because ceramic waste shares characteristics and properties similar to coarse aggregate materials, such as hardness, and has the potential to reduce negative environmental impacts and the depletion of raw materials. Therefore, this research adopts an experimental method at the laboratory of the National Education University in Denpasar by creating five different variations of cylindrical specimens, each with three samples. The ceramic waste variations used are 0%, 10%, 15%, 20%, and 40%. By using an FAS value of 0.6, the slump value was obtained, where the larger the ceramic waste mixture value, the smaller the slump value, as this occurs due to the water absorption value in the ceramic waste being 10.51%. However, despite this, the slump value still falls within the planned range of 5.0 cm to 12.0 cm, and for the planned compressive strength value, which is 175 kg/m2, the highest average concrete strength value is found in the 0% variation, which is 16.01 MPa or equivalent to 192.83 kg/cm2. The concrete with a 10% variation has a compressive strength of 15.21 MPa or 183.25 kg/cm2, the concrete with a 15% variation has a compressive strength of 15.01 MPa or 180.82 kg/cm2, the concrete with a 20% variation has a compressive strength of 13.64 MPa or 164.38 kg/cm2, and the concrete with a 40% variation has a compressive strength of 9.87 MPa or 118.96 kg/cm2. This research can be used as additional literature or as an evaluation material for further research.
