Authors: Marstijepovic Nada , Cvrk Sead , Gagic Radmila , Filipovic Ivan , Nikolic Danilo
Published: January 2023

As a carbon neutral fuel, biodiesel is one option in future IMO scenarios for reducing carbon intensity in shipping sector, and at same time reducing emission of pollutants. Some oily wastes, such as waste from olive oil production, might be used for production of second-generation biodiesel. The current study looks into the effect of biodiesel on the characteristics of gaseous pollutant emissions of NOx and CO from slow-speed two-stroke marine Diesel engines that do not have any after-treatment devices or engine control technology installed to reduce gaseous pollutant emissions. While the ship was berthed in the harbor, tests were performed on two separate loads at 210 rpm. The engine was powered by diesel fuel and blends of 7%, 20%, and 25% v/v of biodiesel derived from oily wastes generated during olive oil processing. For biodiesel production in lab conditions, base-catalyzed transesterification was implemented. According to the findings, there are tendencies of reduced gaseous emissions when utilizing blended fuels.

Authors: Wang Zheng , Suen Kwok , Zhao Zidong
Published: January 2023

The temperature separation effects of vortex tubes have been widely studied in open systems, using mainly air or N2 as the working fluid. When a vortex tube is employed in a closed thermal system, more fluid choices, such as refrigerants, could be considered. Different to air, refrigerants have quite varied thermal-physical properties, and research of the thermal-physical properties? influence on the temperature separation effect is rather limited. Based on CFD simulated temperature separation effect of eight refrigerants (R152a, R290, R134a, R600a, R143a, R245fa, R227ea, and R218), this study attempts to gain a better insight into how their properties could be related to compare their temperature separation performance. The analysis shows for small mass-flow ratios at the cold end, the cooling effect can be assessed by the relative values of their isentropic expansion exponent. The results also suggest that a large thermal diffusivity and kinematic viscosity, and a small vapour density and Joule-Thomson coefficient would lead to better heating effects.

Published: January 2023

Solar energy is a pure and reproducible energy. China has paid more and more consideration to the investigation and employment of solar energy. The investigation focuses on the phenomenon of PID capability degradation of inactivation mediums for instance alumina/silicon nitride in transparent silicon high-efficiency solar cells. Through the laboratorial investigation on the effect of individual in-activation membrane processes on the PID damping behavior, it is found that the deposition approach of silicon oxide and silicon nitride inactivation membranes on the surface of transparent silicon cells directly affects the PID damping. Excellent anti-PID capability; single-layer silicon oxide membrane with the same thickness has better anti-PID capability than silicon nitride membrane. Double-layer silicon oxide/silicon nitride superimposed membrane with the enhancement of refractive index, the anti-PID damping capability gradually enhancements, and better anti-PID capability than monolayer silicon nitride. Investigation on the PID capability damping of inactivation mediums is of great significance to further the capability of solar cells and help to further the effective employment of solar energy.

Authors: Finbarrs-Bello Elizabeth
Published: January 2023

Hepatotoxicity is a common drug adverse effect and gentamycin has been linked to hepatotoxic adverse reactions. Folklore and ethnobotanical studies indicate Eugenia uniflora L is used in the treatment of gastrointestinal ailments and has exhibited diverse biological activities. We investigated the hepatoprotective potential of this plant in treating gentamycin-induced hepatoxicity and compared the effect with Celebrex a COX2 selective inhibitor. Twenty-eight male adult Wistar rats average of 225g were used for the study and randomised into groups as described: normal control( normal saline), negative control: Gentamycin (40mg/kg. i.p), positive control; Gentamycin (40mg/kg. i.p) +5mg/kg Celebrex. Extract low dose: Gentamycin (40mg/kg i.p)+(50mg/kg) Eugenia uniflora L. leaves, intermediate-dose: Gentamycin (40mg/kg i.p) +100mg/kg Eugenia uniflora L leaves, high dose : Gentamycin (40mg/kg, i.p)+ (200mg/kg, ) of Eugenia uniflora L leaves. Our findings indicate that the body weight was unaffected throughout the experiment, as clearly demonstrated by the lack of significant variability (p<0.05). Hepatotoxicity was confirmed by dose-dependent alteration in Liver marker enzymes, including AST, ALT, and ALP. Eugenia uniflora L leaves were able to ameliorate the levels of these liver enzymes to a normal level. Liver tissue revealed a dose-dependent curative effect with Eugenia uniflora L compared to the COX2 inhibitor (Celebrex) treatment. Consequently, we hereby report, for the first time, that an aqueous extract of Eugenia uniflora L leaves confers hepatoprotection against gentamycin-induced hepatoxicity in Wistar rats.

Published: January 2023

A pandemia de covid-19 afetou praticamente todas as esferas da vida humana. No campo econômico, ela impactou, fortemente, a atividade medida pelo Produto Interno Bruto (PIB) em 2020, com recuperação cíclica ao longo de 2021. Contudo, o PIB é um indicador médio para o Brasil, havendo diferenças entre setores e regiões. O objetivo deste artigo foi analisar quais foram os efeitos da pandemia sobre o volume de recursos do Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação (Fundeb) e na dinâmica redistributiva dos fundos, incluindo análise da evolução dos valores dos pisos nacionais por aluno. O Fundeb é a mais importante política de financiamento da educação básica brasileira, representando metade do total de recursos públicos investidos na educação pública como um todo. A abordagem metodológica utilizada consiste em uma análise descritiva dos dados oficiais sobre os recursos financeiros do Fundeb desagregados por fonte de receita, PIB, arrecadação do Imposto sobre Circulação de Mercadorias e Serviços (ICMS) e total de matrículas. O artigo mostra que a pandemia afetou, sim, o Fundeb. Os resultados apontam que, em 2020, houve queda no volume de recursos do Fundo, acompanhando o movimento do PIB, porém, com um declínio menos acentuado devido à menor queda do ICMS, principal fonte de receita do Fundo. Em 2021, o Fundeb mostrou grande crescimento, seguindo a recuperação cíclica da economia ao período pré-pandêmico, mas com um percentual mais acentuado, dado o recorde no crescimento do ICMS e dos fundos de participação. Contudo, a grande recuperação do Fundeb em 2021 não ocorreu de maneira uniforme nos 27 fundos estaduais, afetando a relação entre os valores mínimos por aluno entre esses fundos. O trabalho destaca ainda o papel essencial que o ICMS e os fundos de participação têm no financiamento da educação básica.

Published: January 2023

This study aims to reveal hybridity and liminality in Jhumpa Lahiri's short story entitled A Temporary Matter. This research is a qualitative research with a postcolonial approach. The theory used in this research is postcolonialism theory by Homi K. Bhabha. The methods applied in this study include data collection methods and data analysis methods. The data obtained were taken from the speech of the characters and the narrator in the short story A Temporary Matter. Bhabha in The Location of Culture (1994) discusses hybridity in society during the post-colonial era and is applied to diaspora literature. Hybridity is related to human culture and identity. Culture and identity are formed dynamically, they experience development, progress, and decline according to conditions and circumstances. Diaspora literature is produced from the writings of people living outside the country and/or writings that contain diaspora experiences. In the process of hybridity, there is a gap between the two cultures. The gap is called liminality in which there is repression of the (colonial) past that is not revealed. One of the writers included into the category of diaspora writers is Jhumpa Lahiri. In A Temporary Matter, she shows the hybridity experienced by the two main characters of Indian descent living in the United States. They were husband and wife; Shukumar and Shoba. They experienced cultural adaptation to cultures outside India. In their lives, cultural mixing occurs. This mixture is seen in the food, clothing, and language they use. Between these mixtures, several gaps fill the transition. This is found in the main character's utterances.

This research aims to analyze the types of metaphors used and contained meanings contained in a collection of poems by William Blake. A metaphor is a part of figurative language that compares one thing to another. The researcher used a descriptive employed in study qualitative method to identify a collection of classic poetry by William Blake. The researcher uses the theory of Lakoff, George, and Johnsen (2003) to analyze the conceptual metaphors that shape the reality of 'life' which is reflected in poetry. There are three steps in collecting research data: observation, selection, and classification. This research result shows that ninety-five metaphorical lyrics are contained in the ten of classic collections of poetry by William Blake. The data were gathered using a collection of poems from three types of conceptual metaphors: structural, orientational, and ontological. The types of metaphors found in this research are ontological metaphors. And in reverse, the meaning of each metaphor depends on the type used in the poem. In conclusion, the poems by William Blake have a high imagination based on experiences as well as advice to the readers.

Published: January 2023

Let $G$ be an abelian group and $S$ a given multiplicatively closed subset of a commutative $G$-graded ring $A$ consisting of homogeneous elements. In this paper, we introduce and study $G$-graded $S$-Noetherian modules which are a generalization of $S$-Noetherian modules. We characterize $G$-graded $S$-Noetherian modules in terms of $S$-Noetherian modules. For instance, a $G$-graded $A$-module $M$ is $G$-graded $S$-Noetherian if and only if $M$ is $S$-Noetherian, provided $G$ is finitely generated and $S$ is countable. Also, we generalize some results on $G$-graded Noetherian rings and modules to $G$-graded $S$-Noetherian rings and modules.

Abamectin, Hexythiazox and Spiromesifen Resistance in Populations of Tetranychus urticae Koch (Acari:Tetranychidae) Collected from Cucumber Greenhouses in Tokat Province
Authors: Balkan Tarık
Published: January 2023

Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important pests in greenhouses. This harmful pest has rapidly developed high resistance to many classes of acaricides. In this study, T. urticae populations were collected from cucumber greenhouses in Gümenek village, Tokat, Turkey. Growers in this location use acaricides such as abamectin, hexythiazox and spiromesifen to suppress T. urticae populations. The study aimed to determine the resistance levels of T. urticae populations against to mentioned acaricides. The LC50 values of the collected populations were determined by the spray tower-leaf disc method. The resistance rates were found by dividing the LC50 values of the collected greenhouse populations by the LC50 value of the susceptible population. The resistance levels of T. urticae were determined to be between 1.88-2.14-folds against abamectin, 1.67-1.84 folds against hexythiazox and 1.77-2.09 folds against spiromesifen. According to these results, a low rate of resistance development was observed against abamectin, hexythiazox and spiromesifen.

Published: January 2023

Phosphorous is an essential macronutrient for plant growth and development. Most of the soil is deficient in plant available phosphorous and due to economic limitations majority of Ethiopian farmers applied inadequate fertilizers. It is essential to stabilize a mechanism to access P for plants with an efficient, cheap, and eco-friendly approach for enhanced crop growth and production. The main objective of this study was to screen efficient phosphate solubilizing bacteria from tomato rhizosphere soil. Using halo zone formation on PVK agar medium, more than 400 PSB isolates were isolated from 13 rhizosphere soil samples. By evaluating SI, texture in the culture-re-culturing process, liquid medium pH change efficiency and growth rate, upmost three promising PSB isolates (K-1-29, K-10-27, and K-10-41) were selected. Incubation of the isolates in PVK broth for five days showed significant pH reduction. For instance, isolate K-10-41 showed significant pH change (4.02) which indicates the organic acid production. Isolation and evaluation of efficient phosphate solubilizing bacteria maintain soil fertility, promote plant growth, induce plant response to pathogens, reduce agrochemical consumption and promote sustainable agriculture. Therefore, these selected PSB isolates need further detailed study for taxonomic identification, plant growth promotion, host range, and phytopathogen response. Local isolation improves environmental adaptation and indigenous competition.
Farmer Perception of Trees in a Semiarid Agroecological Zone
Authors: Olowu Eniola Ajibola , Riley Ian Timothy
Published: January 2023

Trees in upland, semiarid agroecological zones typically require water efficiency due to low rainfall, cold and dry temperatures as in Niğde Province, Central Anatolia, Türkiye. This study quantitatively assessed farmer perception of ecosystem services and production advantage of trees in a semiarid zone. Forty-nine farmers in Niğde Province were surveyed. The survey evaluated two major factors: ecosystem services and production advantage using eleven indicators. The responses were grouped by age, gender, education, district class (rural and urban) and farm settlement (rural and urban) and were analysed by test of association (χ2) at P≤0.05. Most farmers had knowledge of trees in their environment and mainly supported the perspective that trees were important mainly for cultural and provisioning ecosystem services. However, they held the opinion that having trees on their farmer was a production disadvantage in a semiarid agroecological zone. Although there were no gender differences in their perspectives, there were significant difference by age, education, district class and farm settlement. Farmers in this semiarid agroecological zone seemed more interested in trees with evident ecosystem services and production advantage such as improved crop yield, water efficiency, weed and pest management, ease of harvesting as well as reduced overall production cost. By implication, trees with multiple benefits are required if further planting by farmers is to be encouraged for agroecosystem improvement. In addition, tree choice will be based on farmer perception of the benefits of trees for ecosystem services and production advantage and further research to identify and promote trees that benefits the widest range of agroecosystems.

Authors: Khaled Sanaa , Al Wardany Hiba , Al Bast Ward
Published: January 2023

Labneh is one of the most consumed dairy products in the Lebanese community, on breakfast, as a snack or on dinner, plane or mixed with herbs. Its various health benefits plus its acceptability among people makes it an important part of the Lebanese diet. In both its synthetic and homemade forms, several additives are usually incorporated to enhance its flavor and offer a variety of tastes. The problem with Labneh is its short shelf life, as well as its sensitive sensory profile. That is why most industries mix chemical additives with Labneh to prolong its shelf life and conserve its taste. The aim of this research is to preserve Labneh naturally by adding Moringa Oleifera dried leaves to extend its shelf life and inhibit rapid spoilage. Working on a natural preservation of Labneh instead of chemical preservation will be assessed by the survey’s results and prepare for studying the overall acceptability of the product by making a sensory analysis. The results of the questionnaire showed that the Lebanese community which is not totally aware of Moringa Oleifera benefits and availability, is willing to try fortified Labneh with Moringa as a new product with extended shelf life and more health benefits. The results of the sensory analysis showed that the sensory attributes of the samples with Moringa after 21 days of storage, where not significantly different than normal plane Labneh, which indicate that adding Moringa did not affect the sensory attributes of Labneh giving it more acceptability to consumers.
