History of studying essential oil crops

The article provides a historical overview of the formation and development of the essential oil industry. The main attention is paid to the history of scientific research of essential oil and medicinal plants. Our ancestors may have instinctively selected certain herbs for healing, just as sick animals today seek out plants they wouldn't normally eat. Based on an analysis of the current state, the need has been determined and the priority tasks have been formed for a full-scale revival of essential oil production in the Russian Federation.The problem tatement: in the republics of the former USSR, a number of essential oil plants were cultivated: coriander, lavender, essential oil rose, sage and others. In the 1970-80s the area of cultivation of essential oil plants exceeded 200 thousand hectares. At the same time, the demand for essential oils and other essential oil products was not fully satisfied. With the collapse of the USSR, the essential oil industry declined. The growing areas for most of the essential oil crops ended up on the territory of the newly formed independent states. The cultivation and processing of essential oils in Russia decreased significantly.The goal of the research is substantiation and acquisition of knowledge about the history of emergence and development of essential oil plants, herbal medicine, active substances as a tool for developing a common problem and combining the scientific, industrial and innovative potential of all interested parties.The research methods used are source study, historical-typological and biographical methods. The research results: the opportunity to gain new knowledge about the history of the origin and distribution of essential oil plants, and the creation of a huge food base for animals and people.

Knowledge, perceptions, and practices regarding cooking and storage of olive oil: A consumer survey in Lebanon

BackgroundOlive oil consumption and production are evident among Lebanese households, yet little is known about the knowledge, perceptions, and practices of Lebanese consumers of olive oil. MethodsA total of 610 adolescents and adults who consume olive oil were surveyed using a semi-qualitative questionnaire comprising 47 questions between August 2022 and May 2023. Descriptive analyses of knowledge, perceptions, and practices were conducted in addition to a regression analysis of the predictors of higher knowledge. Results610 participants were included (61.0 % aged <25 years, and 71.5 % females; 53.8 % olive oil producers). Mainly, participants bought their olive oil once (37.0 %) and in bulk (52.8 %), utilized olive oil daily (55.1 %), and used approximately 2 teaspoons per day (27.4 %). In addition, 29.5 % of the participants’ households consumed more than 30 L per year. Most participants described olive oil as ‘fresh’ (66.1 %), expressed a strong preference for domestic olive oil over imported varieties (66.1 %), believed that olive oil is good for consumption without cooking, other oils/fats are better to cook (53.4 %), and 53.1 % favored olive oil based on its color. Regarding storage, 76 % stored olive oil in a closed cabinet, and 36.6 % used tinplate containers. Half the participants were not concerned about the oil being adulterated (50.2 %); 73.4 % trusted olive mills, and 33.1 % had no trust at all in public food safety authorities concerning olive oil and table olives. Finally, 37.2 % considered that the price of olive oil was high relative to other fats and oils. The mean knowledge score ± standard deviation (SD) was 7.33 ± 2.71 over 10. Higher age than 25 years, male gender, living in the South or Bekaa, being married, having a higher reported BMI, obtaining olive oil from self/family/known sources and olive oil mills, purchasing in bulk, and storing in opaque glass containers colored green, or brown were positively associated with knowledge of olive oil. ConclusionOur study reveals high consumption of olive oil but poor related knowledge and practices among consumers. Consumer education programs on olive oil and relevant practices are warranted, especially for young, female, people living in Beirut, single, and lean individuals. Addressing consumer concerns regarding adulteration and strengthening trust in public food safety authorities are needed.

African climate politics and multilateralism: Domestic factors and cross-country variation in climate ambitions

ABSTRACT This article examines how domestic factors explain variations in the ambitions of sub-Saharan Africa (SSA) countries to meet the requirements of the Paris Agreement on Climate Change. Although Africa contributes only 3.8% of global greenhouse gas emissions, it is highly vulnerable to climate change. All 54 African countries have ratified the Paris Agreement, and by May 2022, 44 had submitted updated nationally determined contributions (NDCs), showing strong commitment to mitigating global temperature rise. Although SSA countries’ NDCs are more robust than the global average, significant cross-country variations exist. This article builds on the limited research on these variations to explore whether democracy, GDP, oil consumption, and historical emissions influence NDC ambition across 44 SSA countries. The analysis finds a statistically significant negative relationship between GDP and NDC ambition, while other variables show no significance. This study is crucial for understanding how domestic factors shape climate commitments in SSA.

New cities for a ‘new Kuwait’: planning for national continuity and stability

ABSTRACT An unprecedented new city-building boom is unfolding in Kuwait, with 12 new cities currently underway. As an oil-rich country, Kuwait faces imminent challenges, including peak oil and climate change, which threaten national wellbeing, continuity, stability, and even survival. As a welfare state guaranteeing housing to citizens, Kuwait shares oil wealth, fundamentally shaping urban planning and spatial development. The current national city-building strategy aims to address housing shortages while reducing reliance on oil. Despite the resources allocated to these projects, Kuwait's city building and its relationship to national economic development strategies has received little scholarly attention. This article introduces the 12 new city projects underway, and examines the main actors driving this trend, how new cities connect to the state's development logic for future-proofing the country, and how national sustainability goals and the state's Vision 2035 for a ‘new Kuwait’ shape these projects. Finally, we reflect on the challenges these projects face.

Investigating the impact of credit channels, energy production and oil revenues on agricultural development in sub-Saharan Africa

Development of the agricultural sector can numerously gift the economy by ensuring food security and rural livelihoods, fostering economic growth, reducing poverty, promoting social stability, and achieving sustainable development goals. But agricultural activities especially in Sub-Saharan Africa are faced with numerous challenges like lack of required credits to the farmers, unavailability of needed energy for powering the farm machinery and transportation of farm produce, and fluctuation of crude oil prices which serve as the main source of energy in Sub-Saharan Africa. However, the sequel to these highlighted challenges that face agricultural activities, this study examines the impact of credit channels, energy production, and oil revenue on agricultural development in sub-Saharan Africa using an annual time series covering 21 years (2001–2021) drawn from selected sub-Saharan African countries under study. Using the panel autoregressive distributed lag model (ARDL) as the baseline model and the generalized method of moment (GMM) as the robustness check, we made the following findings. From the ARDL perspective, we found that credit channels have a negative impact on agricultural development. In contrast, energy production and oil revenue have positive and negative significant impacts on the agricultural development of sub-Saharan Africa. Further, results of the Generalized Method of Moment (GMM) revealed that while credit channels have both negative and positive long-run relationships with agricultural development, energy production, and oil revenues have positive and significant long-run relationships with agricultural development in sub-Saharan Africa. The study concludes that credit channels have both negative and positive long-run relationships with agricultural development. In contrast, energy production and oil revenue have negative and significant long-run relationships with agricultural development in sub-Saharan Africa. We recommended effective agricultural credit provision and a mechanized farming system to increase the quality and quantity of food supplies in sub-Saharan Africa.

The conceptual model of Indonesian palm oil supply chain based on blockchain

Abstract Indonesia is the world’s largest producer and consumer of palm oil. However, the palm oil supply chain faces numerous challenges related to actors, traceability, transparency, and sustainability. To address these issues, a conceptual model for a blockchain-based palm oil supply chain in Indonesia is proposed. The model aims to leverage the decentralized and immutable nature of blockchain technology. It incorporates components such as smart contracts, distributed ledgers, and data sharing mechanisms to enhance traceability, transparency, and sustainability in the palm oil supply chain. The research utilized the SSM (Soft System Methodology) and CATWOE (Customer, Actor, Transformation, Worldview, Owner, Environment) methodologies. The actors involved in the palm oil supply chain include smallholders, plantation companies, third-party suppliers, middlemen, traders, palm oil mills, refineries, distributors, retailers, and consumers. The blockchain conceptual model is structured based on a sustainable supply chain model that considers economic, social, and environmental aspects. Blockchain transactions regulate the process of supply chain actors, while stakeholders such as the government, financial institutions, palm oil research organizations, NGOs, and consumers are involved. The blockchain-based supply chain model is expected to address the key issues of the palm oil supply chain, aiming for a sustainable supply chain system. By implementing this model, it is anticipated that the palm oil industry can achieve greater accountability, transparency, and environmental sustainability.

Oil shocks and the transmission of higher-moment information in US industry: Evidence from an asymmetric puzzle

Using a cross-quantilogram approach, this study analyzes the transmission of higher-moment information across US industries with high-frequency (1-min) data. We investigate the effects of oil demand and supply shocks on this transmission, revealing that the impact is asymmetric. Specifically, negative oil price shocks amplify the asymmetric transmission of higher-moment information, whereas positive shocks have the opposite effect. The findings highlight the complexity in information transmission dynamics in response to oil price fluctuations, highlighting the need for policy makers and investors to account for these nuances when assessing risk and making decisions. The results emphasize the critical role of the direction and magnitude of oil prices in shaping the information landscape across industries.

Linear Programming Model for Sunflower Oil Supply Chain Network

Food supply networks are vital to the global economy, producing and consuming products worldwide. Supply chain management (SCM) has emerged as a crucial technique to optimize the integrated network of suppliers, factories, warehouses, customers, and distribution channels. SCM aims to ensure efficient raw material sources, transformation, transportation, and timely customer delivery. Edible oil, a crucial ingredient for cooking and food preparation, is utilized by people from all social classes. Vegetable oils, particularly sunflower, soybean, peanut, and others, are the main source of edible oils, which have less unsaturated fatty acids compared to animal oils. The production and consumption of edible oils have substantial environmental impacts, necessitating increased research to address these implications. Sunflower, a valuable oilseed crop, is grown worldwide due to its short growing season and adaptability to various climates and soil types. Sunflower seeds have high oil and protein content, making them popular for their health benefits. This article uses a linear optimization model for the sunflower oil supply chain from the farmer to the end user. The objective is to minimize the overall transportation cost subject to capacity, demand fulfillment, and waste management.

Application of Aspen Plus to Modelling and Simulation of Neem Seed Oil Extraction

The demand for neem oil keeps on increasing due to its wide applications in pharmaceutical, agro–allied industries, cosmetics and soap production. To avoid wastage of material and safety of operation and personnel, the designed plant must be simulated to predict its performance before actual construction. The property method based on the non–random two–liquid (NRTL) model of Aspen Plus V12 was used to simulate the designed plant and its predicted performances were 87.13% and 99.60% for quantity of neem oil to be obtained from the evaporator and quantity of solvent (ethanol) recovery from the condenser as against 85.93% and 94.93% of the practical result with 1.38% and 4.69% errors respectively. The extracted oil has iodine, acid and saponification values of 60.10 g I2/100 g, 4.2 mg KOH/g and 210.0 mg KOH/g respectively. The fatty acid compositions of oil are oleic acid, 46.61%; stearic acid, 11.83%; palmitic acid, 16.54%; 11 – octadecenoic acid, 3.58%; cis–vaccenic acid, 5.90%; cyclopropaneoctanal, 11.19%; squalene, 0.21% and trimethylsilyl–di(timethylsiloxy)-silane, 4.14%. Based on the quality and fatty acid composition of the extracted neem oil, it is highly recommended for cosmetics and soap production.

Impact of the Mediterranean Diet (Med-Diet) on Cancer and Cardiovascular Disease (CVD) Prevention and Management: A Narrative Review

Cancer and cardiovascular diseases (CVD) are the leading causes of mortality and morbidity worldwide. Dietary patterns play a crucial role in the prevention and management of these life-threatening diseases. Moreover, the Mediterranean diet (Med-Diet) is consistently associated with health benefits. Therefore, the current study attempted to synthesize the contemporary scientific evidence, outlining the impact of Med-Diet on CVD. The key components of this dietary pattern include a high intake of fruits, vegetables, whole grains, seafood, olive oil, and moderate consumption of poultry and dairy products which interact to provide protective effects against these diseases. The Med-Diet emphasizes the use of monounsaturated fats from olive oil and polyunsaturated fats from seafood, which significantly contribute to cardiovascular health. This diet is also rich in antioxidants and phytochemicals, offering potential protective qualities against cancer through combating inflammation and oxidative stress. High fiber content contributes to a healthy digestive system and potentially reduces the incidence of colorectal cancers. While, the Med-Diet alone cannot guarantee complete immunity against these diseases, it is an essential element of a holistic approach to disease prevention and management. Moreover, it also reinforces the importance of incorporating dietary patterns into public health strategies. To strengthen the evidence base, future research should focus on long-term randomized controlled trials in diverse populations.

Frying kinetics and physical properties of air-fried french fries

French fries are processed products made of partially cooked frozen potatoes. The most essential step in making french fries is frying, aiming to produce soft and crunchy product. Using air fryers in the frying process offers the benefit of significantly reducing oil consumption, thereby making it a favorable option for producing lower-fat fried foods. The objectives of the present study were to analyze the physical and chemical characteristics of french fries on the use of oil and time variation in the air frying method and to determine the frying kinetics under the air fryer. Finding the best frying method was carried out using some attributes of Zeleny, such as the frying rate. Frying was controlled at a constant temperature of 180 °C with time variations of 10, 13, and 16 minutes, and variation in the amount of oil, i.e., 2 mL, 4 mL, and without oil. The results showed the physical characteristics of french fries that include moisture content (26.85 – 45.56%), color with indicators L* (64.44 – 68.66), a* (0.01 – 4.80), b* (21.32 – 35.54), color differences (4.57 – 10.60), hardness (120.83 – 559.8 g), springiness (1.15 – 2.82 mJ), chewiness (0.33 – 3.98 mm), gumminess (28.6 – 213.43 g), and cohesiveness (0.2 – 0.41). The variations in the amount of cooking oil in the air frying method significantly affect the redness parameters. The time variation in the air frying method significantly affects moisture content, hardness, gumminess, chewiness, and cohesiveness parameters. Lightness, yellowness, colour differences, and springiness parameters have no significant effect on the variation of oil and time. The chemical characteristic of french fries includes fat content (5.78 – 22.42 %). The air frying method without oil used for 13 minutes was considered as the best treatment for frying french fries.

Pengaruh Penambahan Butanol Pada Bahan Bakar Solar Terhadap Karakteristik Pembakaran Single Droplet

Dependence on fossil fuels is one of the most serious threats to the global environment. In addition, petroleum reserves are also decreasing. Meanwhile, the level of oil consumption is always increasing to meet the demand for fuel. Economical and sustainable alternative energy solutions are essential to meet the growing global energy demand without compromising environmental sustainability. One type of alternative fuel that shows very promising potential is biofuel, especially biodiesel. Biodiesel has potential as a more environmentally friendly alternative to diesel fuel, but its low combustion rate and higher viscosity compared to conventional diesel fuel present technical challenges that need to be overcome. The different chemical properties of butanol from biodiesel allow it to have a positive impact on combustion characteristics, such as viscosity, flash point, heating value, and combustion rate. The combustion characteristics that will be studied in this research using single droplet combustion testing include droplet visualization to measure the dimensions of the flame, temperature during the combustion process recorded by a thermocouple, data logger, and video recording during the combustion process to obtain information regarding the ignition delay value. The test steps were repeated five times for each fuel variation and then averaged. In this study, the samples tested included pure diesel, diesel blend with 10% butanol, diesel blend with 20% butanol, diesel blend with 30% butanol, diesel blend with 40% butanol and diesel blend with 50% butanol. From this study, the visualization of the flame is obtained, where the combustion of pure diesel oil droplets has a higher and wider flame, while the flame of the butanol diesel mixture produces a flame whose maximum height is lower than pure diesel oil. The ignition delay time of pure diesel oil is greater than the ignition delay time of the diesel butanol blend. In addition, the maximum combustion temperature produced by each blend is different

Impact of renewable and non-renewable generation on economic growth in Greece

The consumption of coal, oil, and other fossil fuels has raised concerns about climate change. The Kyoto Protocol and the Paris Agreement aimed to address climate change by promoting sustainable clean energy technologies. The UN conference in the United Arab Emirates in December 2023 concluded with an agreement marking the end of the fossil fuel era. All these developments aim to address climate change through the use of clean energy technologies while maintaining economic growth. The connection of climate change with the developing model has gained significant importance on countries’ adjusted plans for climate change. The fossil fuels have a negative impact on economic growth of Greece, implying a continuous dependence from non renewable energy sources and a burden of economic expansion. The reliable estimation of the consequences of climate change on growth, both spatial and temporal, constitutes a decisive parameter for the adjusted plan not only in short term level but also in a long term horizon. Focusing on the improvement of energy efficiency, on the maximization use of renewable energy sources in Greece, on the emphasis given to technologies and fuels storage as well as alternative technologies of energetic and industrial sector, the achievement of energetic and climate transition designed on Greece will be feasible on a long term strategy. The results showed that the growth of renewable energy sources to produce electric energy is necessary for the sustainable growth of Greece. Specifically, the results of ARDL model showed that the renewable energy sources have a positive impact on economic growth in Greece in the long run, and the non-renewable energy sources have a significant effect on economic growth in the short run. These results imply that the aim for investments on renewable energy sources from policy makers should be direct mainly on regions with high levels of carbon dioxide emissions due to lignite combustion.

Features of the operation of the lubrication system for lubricating ships' low-speed engines

The article examines the optimization of high-alkaline cylinder oil consumption in lubrication systems of marine low-speed engines (MODs), as well as the peculiarities of operation of the cylinder lubrication system in view of modern trends in the development of low-speed marine engines. An overview of the lubricator lubrication systems of the cylinders of marine main engines was carried out and possible prospects for improving the lubricator lubrication systems of the cylinders of marine diesel engines were considered. Attention is paid to the causes of occurrence and methods of combating a whole range of problems, which represent the possibility of increased wear of cylinder sleeves, pistons, piston rings, this is related to the type and grade of fuel and its sulfur content. Sulfur in the fuel is neutralized with the help of cylinder oils with high alkalinity, problems arise when changing the grade of fuel, this requires changing the brand of cylinder oil (CLO BN). The possibility of using a cylinder oil mixing system (ACOM) to neutralize sulfur in the fuel and improve protection against low-temperature corrosion of MOD cylinder liners is proposed and considered. This system mixes and doses cylinder oil depending on the load of the ship's engine and the type of fuel. ACOM allows the dosing of oil on marine engines operating in dual fuel consumption (SDF) modes, where the ratio between pilot (ignition) and gas fuel is defined, the system mixes two different types of cylinder oil into one with the required BN base number, it can be determined as the oil's ability to neutralize acids produced during use. The results of optimal consumption of cylinder oil, which ensures minimal wear of cylinder liners of a diesel engine, are given. Features of lubrication regimes and control of the technical condition of the cylinder group of marine low-speed diesel engines during their operation at reduced rotation frequency are described
