Diet to Stop Hypertension: Should Fats be Included?

International guidelines emphasize advice to incorporate dietary measures for the prevention and in the management of hypertension. Current data show that modest reductions in weight can have an impact on blood pressure. Reducing salt and marine oils have also shown consistent benefit in reducing blood pressure. Whether other dietary constituents, in particular the amount and type of fat that play important roles in cardiovascular prevention, influence blood pressure sufficiently to be included in the management of hypertension is less certain. In this review, we provide a summary of the most recent findings, with a focus on dietary patterns, fats and other nutrients and their impact on blood pressure and hypertension. Since reducing salt consumption is an established recommendation only corollary dietary advice is subject to the current review. Population studies that have included reliable evaluation of fat intake have indicated almost consistently blood pressure lowering with consumption of marine oils and fats. Results with vegetable oils are inconclusive. However dietary patterns that included total fat reduction and changes in the nature of vegetable fats/oils have suggested beneficial effects on blood pressure. Plant-based foods, dairy foods and yoghurt particularly, may also lower blood pressure irrespective of fat content. Total fat consumption is not directly associated with blood pressure except when it is part of a weight loss diet. Consumption of marine oils has mostly shown moderate blood pressure lowering and possibly greatest effect with docosahexaenoic acid-rich oil.

Olive oil consumption is associated with lower cancer, cardiovascular and all-cause mortality among Italian adults: prospective results from the Moli-sani Study and analysis of potential biological mechanisms.

Olive oil consumption has been reportedly associated with lower mortality rates, mostly from cardiovascular diseases, but its potential impact on cancer death remains controversial. Moreover, biological mechanisms possibly linking olive oil consumption to mortality outcomes remain unexplored. We longitudinally analysed data on 22,892 men and women from the Moli-sani Study in Italy (follow-up 13.1 y), to examine the association of olive oil consumption with mortality. Dietary data were collected at baseline (2005-2010) through a 188-item FFQ, and olive oil consumption was standardised to a 10 g tablespoon (tbsp) size. Diet quality was assessed through a Mediterranean diet score. Multivariable-adjusted Cox proportional hazard models, also including diet quality, were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). The potential mediating role of inflammatory, metabolic, cardiovascular and renal biomarkers on the association between olive oil intake and mortality was evaluated on the basis of change-in-estimate and associated p values. Multivariable HRs for all-cause, cancer, cardiovascular and other cause mortality associated with high (>3 tbsp/d) versus low (≤1.5 tbsp/d) olive oil consumption were 0.80 (0.69-0.94), 0.77 (0.59-0.99), 0.75 (0.58-0.97) and 0.97 (0.73-1.29), respectively. Taken together, the investigated biomarkers attenuated the association of olive oil consumption with all-cause and cancer mortality by 21.2% and 13.7%, respectively. Higher olive oil consumption was associated with lower cancer, cardiovascular and all-cause mortality rates, independent of overall diet quality. Known risk factors for chronic diseases only in part mediated such associations suggesting that other biological pathways are potentially involved in this relationship.

DISPLACEMENT OF OIL BY MICELLAR SOLUTION WITH NANOPARTICLES FROM POROUS MODEL WITH CORE MATERIAL

Enhanced oil recovery (EOR) techniques play an important role in maintaining oil production worldwide. These methods are given special attention due to the constant decline in the availability of oil resources. One type of EOR is the tertiary method - a chemical method that involves the use of synthetic substances for mining. Liquid flooding in the presence of a surfactant is a common chemical EOR, and microemulsions belong to these systems. The injection of the microemulsion rim reduces the interfacial tension between the crude oil and the formation fluid, which results in the mobilization of a significant portion of the residual oil. Recently, the possibility of simultaneous use of nanoparticles and chemicals to increase the efficiency of the processes of increasing oil recovery has been considered. In this work, nanoparticles participate in the role of microemulsion stabilization, and their joint effect on the displacement capacity of oil from the bulk model of a porous medium is also analyzed. The work is aimed at studying the effect of adding silicon oxide nanoparticles to a microemulsion solution, which is an agent for displacing viscous oil from a bulk porous medium. In the experiment, laboratory studies of oil displacement by various compositions, including surfactants, salt, alcohol and nanoparticles, were carried out on two types of bulk models assembled from glass beads and quartz sand, phase saturations were determined at different points in time, and displacement capacity graphs were built. The oil displacement study was carried out for six liquids: water, mineralized water, nanofluid, aqueous solution with surfactant, also a solution for microemulsion without and with the addition of nanoparticles. It has been found that the effect of adding nanoparticles to the microemulsion composition in the case of bulk models consisting of glass beads leads to a slight increase in the volume of displaced oil. In the case of bulk models consisting of core material, an increase in residual oil saturation is observed, which is associated with adsorption of particles on the surface of core material.

Life cycle analysis of the wastewater treatment system in Zabol Industrial Town: Environmental impacts, energy demand, and greenhouse gas emissions.

Use of effective environmental remediation facilities represents a crucial strategy for water reclamation and addressing the challenges of water scarcity. The objective of this study was to assess the wastewater treatment system (WWTS) in Zabol Industrial Town using the life cycle assessment method. Primary data, collected annually for a functional unit of 1 m3 of wastewater treatment, were subjected to analysis using the ReCiPe, Cumulative Energy Demand, and Intergovernmental Panel on Climate Change (IPCC) methods. Human carcinogenic toxicity (50%), freshwater ecotoxicity (13%), and marine ecotoxicity (10%) were the primary environmental impacts due to the WWTS performance. The discharge of heavy metals during sludge generation, coupled with the consumption of natural gas and oil, especially for electricity production, were pivotal factors contributing to the environmental burdens observed. Furthermore, chemical oxygen demand (COD) (56.34%), electricity consumption (>15.47%), and total phosphorous (>4.49%) significantly threatened human health and ecosystem categories, while fossil fuel consumption had the greatest impact on resources. Nonrenewable fossil fuels, namely, natural gas (47.2%) and oil (38.27%), played a predominant role in the energy provision of the system. The IPCC analysis depicted the emissions of CO2 (86.77%) and CH4 (12.16%) stemming from the process of electricity generation. Based on the outcomes of the sensitivity analysis, implementing a 10% increase in COD yielded an increment in all impacts within the range of 1.40% to 6.83%. Given Iran's geographic location and the unique climatic conditions in Zabul, use of solar and wind energy to energize the WWTS can substantially alleviate its environmental burdens. This study presents a comprehensive framework for evaluating the environmental impact, energy consumption, and carbon footprint of a WWTS. Integr Environ Assess Manag 2024;00:1-12. © 2024 SETAC.

Palm oil as part of a high-fat diet: advances and challenges, or possible risks of pathology?

Nutritional status disorders have the most significant impact on the development of cardiovascular and oncologic diseases; therefore, the interest in the study of palm oil as among the leading components of nutrition has been increasing. The data examined in this review were sourced from the Scopus, SCIE (Web of Science), PubMed and PubMed Central, MEDLINE, CAPlus/SciFinder, and Embase databases; experts in the field; bibliographies; and abstracts from review analyses from the past 15 years. This review summarizes recent research data focusing on the quantitative and qualitative composition of nutrition of modern humans; concepts of the relationship between high-fat diets and disorders of insulin functioning and transport and metabolism of fatty acids; analyses of data regarding the palmitic acid (16:0) to oleic acid (18:1) ratio; and the effect of diet based on palm oil consumption on cardiovascular risk factors and lipid and lipoprotein levels. Several studies suggest a potential vector contributing to the transmission of maternal, high-fat-diet-induced, addictive-like behaviors and obesogenic phenotypes across generations. The relationship between cholesterol accumulation in lysosomes that may lead to lysosome dysfunction and inhibition of the autophagy process is analyzed, as is the progression of inflammatory diseases, atherosclerosis, nonalcoholic liver inflammation, and obesity with associated complications. Data are discussed from analyses of differences between rodent models and human population studies in the investigated different effects of palm oil consumption as a high-fat diet component. A conclusion is reached that the results cannot be generalized in human population studies because no similar effects were observed. Although there are numerous published reports, more studies are necessary to elucidate the complex regulatory mechanisms in digestive and nutrition processes, because there are great differences in lipoprotein profiles between rodents and humans, which makes it difficult to reproduce the pathology of many diseases caused by different types of the high-fat diet.

Circular behavior of oil consumption and the impact of oil prices with the Fourier approach

In the changing world, oil continues to be important in energy production. Using monthly data from 1965–2022, the permanency of oil consumption fluctuations was investigated. Fourier-based Granger causality tests were used to examine cause-and-effect relationships between variables. Long-term relationships were estimated using Fourier-based Engle Granger cointegration tests. Unlike previous research, this study considers the long and short-term effects of countries that consume the most and least oil, as well as on a global scale, from different perspectives, examining oil price fluctuations together, and estimating these analyzes using the Fourier approach. Oil consumption fluctuations appear temporary in New Zealand and Luxembourg but permanent in all other countries. Oil consumption and prices share a causal relationship in the US, Japan, New Zealand, and Luxembourg, but no relationship elsewhere. A long-term relationship exists between oil consumption and prices in the US, India, Saudi Arabia, Russia, Japan, South Korea, Canada, Mexico, and Estonia. In other countries, no long-term relationship is found between these two variables. Error correction model estimation shows only the equation for Japan can be interpreted based on statistical significance. A one-unit deviation between oil consumption and prices can reach equilibrium in 20 months.

Consumption of Olive Oil and Diet Quality and Risk of Dementia-Related Death.

Age-standardized dementia mortality rates are on the rise. Whether long-term consumption of olive oil and diet quality are associated with dementia-related death is unknown. To examine the association of olive oil intake with the subsequent risk of dementia-related death and assess the joint association with diet quality and substitution for other fats. This prospective cohort study examined data from the Nurses' Health Study (NHS; 1990-2018) and Health Professionals Follow-Up Study (HPFS; 1990-2018). The population included women from the NHS and men from the HPFS who were free of cardiovascular disease and cancer at baseline. Data were analyzed from May 2022 to July 2023. Olive oil intake was assessed every 4 years using a food frequency questionnaire and categorized as (1) never or less than once per month, (2) greater than 0 to less than or equal to 4.5 g/d, (3) greater than 4.5 g/d to less than or equal to 7 g/d, and (4) greater than 7 g/d. Diet quality was based on the Alternative Healthy Eating Index and Mediterranean Diet score. Dementia death was ascertained from death records. Multivariable Cox proportional hazards regressions were used to estimate hazard ratios (HRs) and 95% CIs adjusted for confounders including genetic, sociodemographic, and lifestyle factors. Of 92 383 participants, 60 582 (65.6%) were women and the mean (SD) age was 56.4 (8.0) years. During 28 years of follow-up (2 183 095 person-years), 4751 dementia-related deaths occurred. Individuals who were homozygous for the apolipoprotein ε4 (APOE ε4) allele were 5 to 9 times more likely to die with dementia. Consuming at least 7 g/d of olive oil was associated with a 28% lower risk of dementia-related death (adjusted pooled HR, 0.72 [95% CI, 0.64-0.81]) compared with never or rarely consuming olive oil (P for trend < .001); results were consistent after further adjustment for APOE ε4. No interaction by diet quality scores was found. In modeled substitution analyses, replacing 5 g/d of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8% (95% CI, 4%-12%) to 14% (95% CI, 7%-20%) lower risk of dementia mortality. Substitutions for other vegetable oils or butter were not significant. In US adults, higher olive oil intake was associated with a lower risk of dementia-related mortality, irrespective of diet quality. Beyond heart health, the findings extend the current dietary recommendations of choosing olive oil and other vegetable oils for cognitive-related health.

Impacts of Renewable and Disaggregated Non-Renewable Energy Consumption on CO2 Emissions in GCC Countries: A STIRPAT Model Analysis

This research investigates the effects of renewable (REC) and disaggregated non-renewable energy consumption (coal, oil, and natural gas) on CO2 emissions (CO2) in GCC countries, employing the STIRPAT model. The research also compares the impact of various non-renewable energy (NREC) sources to identify their contributions to CO2 emissions. Demographic factors like population and economic growth are considered main determinants of CO2. Panel data econometric methods are used, including diagnostic tests and unit root tests, to found long-run relationships among the variables. The study reveals significant positive associations between coal, natural gas, oil consumption and CO2, with oil having the highest impact. Conversely, REC shows a significant negative correlation with CO2. Economic growth and population are also linked to increased CO2. The findings emphasize the need for strategies promoting renewable energy usage, energy efficiency, public transportation, carbon pricing, and research in green technologies to alleviate CO2 and enhance sustainable development in the GCC countries.

Achieving environmental sustainability goals through capitalizing on renewable energy channels: Role of green finance, resources productivity and geopolitical situation in the MENA region

Environmental sustainability is essential to the country's financial position and economic growth. Geopolitical situations and green activities significantly contribute to enhancing sustainable development goals. The purpose of this study is to evaluate the impact of green finance, investment in renewable energy sources and geopolitical risk on the environmental sustainability of the Middle East and North America (MENA) region over the period 2000–2021. When using a cross‐sectional dependence autoregressive distributed lag model (CS‐ARDL), it is discovered that a rise in geopolitical risk will decrease environmental performance in the form of carbon dioxide emission. At the same time, the other factors (green finance and investment in renewable energy) have a positive relationship with sustainability. This observation can be ascribed to the association between increased geopolitical risk and the inclination of crude oil consumers, who are most affected by such risk, to contemplate renewable energy as an alternative to conventional energy sources. This finding could also be attributed to the fact that clean energy is becoming more affordable. In addition, the augmented mean group model findings provide more evidence that a negative linkage is found between geopolitical risk and environmental sustainability. The findings have repercussions for regulators as well as investors who are active in the renewable energy markets.

Characterization of Phenolic Compounds in Extra Virgin Olive Oil from Granada (Spain) and Evaluation of Its Neuroprotective Action

The olive oil sector is a fundamental food in the Mediterranean diet. It has been demonstrated that the consumption of extra virgin olive oil (EVOO) with a high content of phenolic compounds is beneficial in the prevention and/or treatment of many diseases. The main objective of this work was to study the relationship between the content of phenolic compounds and the in vitro neuroprotective and anti-inflammatory activity of EVOOs from two PDOs in the province of Granada. To this purpose, the amounts of phenolic compounds were determined by liquid chromatography coupled to mass spectrometry (HPLC–MS) and the inhibitory activity of acetylcholinesterase (AChE) and cyclooxygenase-2 (COX-2) enzymes by spectrophotometric and fluorimetric assays. The main families identified were phenolic alcohols, secoiridoids, lignans, flavonoids, and phenolic acids. The EVOO samples with the highest total concentration of compounds and the highest inhibitory activity belonged to the Picual and Manzanillo varieties. Statistical analysis showed a positive correlation between identified compounds and AChE and COX-2 inhibitory activity, except for lignans. These results confirm EVOO’s compounds possess neuroprotective potential.

Potential for low-emissions oil palm production in Indonesia: insights from spatiotemporal dynamics

Rising global demand for palm oil has created environmental pressures related to deforestation, burning, and peat exploitation, which in turn drives increased greenhouse gas (GHG) emissions. GHG emissions in oil palm (OP) production are known to vary spatially. However, temporal changes across contrasting management and soil types, are less well studied. This paper quantifies spatiotemporal GHG emissions across contrasting regions, management types, and soil types for the period 1990–2019 to assess the potential for reducing emission. The study focusses on Indonesia, as the biggest producer of OP, and in particular on the North Sumatra and Riau provinces, where OP is intensively produced. GHG inventories in 5 year time steps were constructed to investigate the change in drivers of emissions using spatial data, resampled to a 500 m grid. Total GHG emissions were found to have increased in both regions due to expanding OP production. However, results show a reduction in emissions flux from 1.98 to 1.15 Ton Ceq. ha−1yr−1 in North Sumatra and 9.63–2.67 Ton Ceq. ha−1yr−1 in Riau over the study period. This reduced flux was linked to the decreased deforestation and burning activities, together with increased biomass increment from lower carbon stock area conversion to OP. In both provinces, smallholder plantations emitted fewer emissions than industrial ones, and production on organic soils resulted in consistently higher emissions than on mineral soils. In North Sumatra, emissions under all management and soil types were found to decrease. In Riau, however, GHG emissions on organic soils regardless of management types, remained high. Our findings emphasise that potential for low-emissions OP production is attainable by reducing emissions per unit area through an improved understanding of GHG emissions spatiotemporal variability and their drivers. These contribute to reinforcing ongoing government regulations and guiding the industry towards low-emission OP productions.

Non-alcoholic fatty liver disease among patients undergoing ultra-sonography abdomen and its associated factors in a tertiary care hospital, Kakinada

Background: Non-alcoholic fatty liver disease (NAFLD) presents a growing global health concern, characterized by the accumulation of hepatic lipids in the absence of significant alcohol consumption. Its prevalence has surged worldwide, including in India, where it has reached alarming levels. Despite its silent progression, NAFLD can lead to severe complications, including liver cirrhosis and hepatocellular carcinoma. Objectives of the study to assess prevalence and its associated factors, which are essential for effective management and prevention strategies. Methods: An observational, analytical cross-sectional study was conducted in a tertiary care hospital in Kakinada, Andhra Pradesh, from June to July 2022. Among 100 subjects, chosen through the simple random sampling. Ethical approval was granted before conducting study. Data on demographics, lifestyle risk factors, anthropometry, and ultrasound findings were collected using a pretested and validated case record form. Statistical analysis was carried out using SPSS software, employing appropriate tests to explore associations between NAFLD and various variables. Results: Among 100 participants, the prevalence of NAFLD was found to be 41%. Significant associations were observed between NAFLD and variables such as BMI (p=0.034), waist-hip ratio (p=0.002), and history of diabetes mellitus (p=0.000). Lifestyle factors, including increased cooking oil consumption, were identified as significant risk factors. Conclusions: The study highlights the high prevalence of NAFLD among subjects undergoing ultrasound abdomen in Kakinada. Significant associations were observed with BMI, waist-hip ratio, and diabetes mellitus history. Promoting healthy behaviours is crucial for NAFLD prevention and management.

The Nexus between Oil Consumption, Economic Growth, and Crude Oil Prices in Saudi Arabia

The energy revolution in Saudi Arabia has accelerated significantly since 2016, driven by the National Vision 2030. Significant changes to energy subsidies took place, and the renewable energy sector has seen rapid growth. The paper presents an empirical analysis of the Saudi energy transition by emphasizing the drivers of fuel consumption in KSA. It primarily attempts to explore the long-run (LR) connection between oil consumption and several economic variables such as economic growth, crude oil prices, investment, and the labor force in Saudi Arabia (KSA) from 1991 up to 2021. The paper implemented the vector error correction model (VECM) and performed different diagnostic tests to provide more evidence about the validity and robustness of the tests. The empirical findings highlighted how important the labor force, savings, GDP, and crude oil price are in determining oil consumption for KSA. The law of demand is significantly present, which negatively affects oil consumption for KSA as an oil exporting country. The results also supported the existence of a long-term direct correlation between the variables and oil consumption. Furthermore, the short-term estimation highlighted that only saving has a negative impact on oil consumption for a single lagged period. Our findings provide governments and regulators with further incentive to slow the expansion in oil consumption, as a larger labor force is demanding more oil to attain the target, faster economic growth, and increased savings are all contributing factors. Our findings are significant because they can assist policymakers, investors, and regulators in generating more efficient oil substitutes and making them affordable for the economy.

The External Financial Crises and Their Role in The Economic Growth Fluctuations in Iraq During the Period (2004-2021)

Financial crises are a concerning and essential phenomenon due to their severe and dangerous negative impact on global stability. These crises have also spread to developing and advanced countries due to their financial and economic openness. The adverse effects of financial crises have had repercussions on global oil prices, which in turn affected economic growth in Iraq, given its dependence on the oil sector. The main objective of the research was to examine the impact of the global financial crisis on economic growth in Iraq. The research utilized deductive methodology and descriptive analysis as the appropriate approach to achieve the research goal and understand the effect of global financial crises on economic growth. The research begins with the hypothesis that the economic growth in Iraq is affected by global financial crises through oil prices in international markets. The researcher utilizes specific indicators of the Iraqi economy, including oil prices, public revenues, public expenditures, and public debt, to demonstrate the impact of global financial crises on these indicators and how this impact reflects on economic growth in Iraq, represented by the gross domestic product (GDP). The research findings highlight several impacts on the Iraqi economy due to various financial crises. These include the 2009 mortgage crisis, which decreased crude oil prices in the global market due to the global economic recession. Additionally, the financial crisis since the second half of 2014 was caused by a decline in crude oil prices due to sluggish global economic growth. Furthermore, the COVID-19 crisis at the end of 2019 had significant financial consequences, accompanied by decreased oil prices. It is evident that the Iraqi economy is directly and unexpectedly affected by financial crises through the oil markets, as the country heavily relies on oil revenues, which constitute a large proportion of the GDP.                                                             Paper: Research paper  

The Role of the Government's Self- Depth in Bearing Financial Pressures in Iraq for the Period (2006-2022)

This study aimed at analyzing the government's self-financing depth in withstanding financial pressures in Iraq during the period (2006-2022). The study assumed that increasing government's financial capacity was having a positive impact on facing financial pressures of public expenditure burdens and economic non-stability in Iraq. The study relied on the inductive and data analysis method to verify the hypothesis of the study and access to results. With reference to the use of the ratio of oil revenues to GDP as deputy for self- financing depth due to the Iraqi government's heavy reliance on oil revenues to finance the general budget. It also used the following indicators as deputy financial pressure: the ratio of public expenditure, consumption, investment, and public debt to gross domestic product, tax effort index, monetary stability coefficient index and exchange rate discipline index. The study found that the financial capacity of the Iraqi government relied heavily on volatile self-financing depending on the volatility of oil revenues in financing current expenditures, which reduced the financial capacity to stand financial pressure. It’s reflected in the government's high financial burden and the existence of economic non-stability (inflation pressure, external debt pressure, foreign currency exchange pressure) in Iraq.

The Effect of the Exchange Rate on Price Stability in Iraq from 2004-2022

This Paper examines how the exchange rate influences price stability in Iraq using the Autoregressive Distributed Lag (ARDL) method. Monthly data covering the period from January 2004 to April 2022 are employed, with the Consumer Price Index (CPI) used as the dependent variable and Exchange Rate (EX), Oil Prices (OILR), Money Supply (M2), Policy Interest Rates (IR), and Government Spending (GOSP) as independent variables. The ARDL bound test results confirm a long-run relationship between the exchange rate and price stability in Iraq; the results indicate that a more robust exchange rate is associated with higher price stability, emphasizing potential benefits from currency strength. The positive link between government spending and price stability suggests the stabilizing impact of fiscal policies. In contrast, the negative association between interest rates and price stability corresponds to expectations of reduced economic activity. Findings on money supply support the quantity theory of money, and the negative relationship between oil revenue and price stability highlights challenges associated with economic reliance on oil. The Paper offers valuable insights for policymakers, emphasizing the importance of exchange rate stability, economic diversification, and precise adjustments in monetary and fiscal policies to ensure sustained price stability in Iraq.     Paper type: Research paper.

Commodity market stability and sustainable development: The effect of public health policies

This study explores the influence of public health policies on commodity market volatility during public health emergencies, such as pandemics, using data from China and the US. We investigate how stringent public health measures can mitigate the effects of pandemics on the stability of commodity markets by stabilizing domestic demand and supply of natural resources. Our findings highlight the interconnectedness between commodity market stability and oil production, showing that firms increase their oil inventories in response to oil market volatility as a precautionary measure. This action, in turn, affects the amount of oil available for production, impacting oil consumption and extraction rates. We demonstrate that stability in the oil market significantly influences not only oil consumption but also has broader implications for sustainable development, green asset markets, and carbon emissions.

Oxidative Stability in Meat (Pectoralis major) of Broiler orally Supplemented with Essential Oils of Allium sativum, Curcuma longa, Zingiber officinale and Cinnamomum zeylanicum

Abstract Lipid oxidation is a normal process in living muscles, but is escalated post-mortem due to the loss of inherent antioxidant defense, which causes quality deterioration of meat. This study investigates the effects of essential oil (EO) supplementation added to the drinking water of broiler chicken on physical properties, antioxidants and lipid oxidation in Pectoralis major during frozen storage. Two hundred one day-old chicks of arbo acre were allocated to 5 groups; control (T1) and the groups supplemented with: Allium sativum (T2), Curcuma longa (T3), Zingiber officinale (T4) and Cinnamomum zeylanicum (T5) at the level of 300ml/L into drinking water throughout a 49-day study. Thereafter, birds were slaughtered and breast meat excised for assessments during a 28-day storage period at 40C using standard procedure. The results show that cooking loss of Pectoralis major from T1 birds was not significantly (P&amp;gt;0.05) different from that of T4, and were significantly higher than those of T2, T3 and T5 birds. Meat from T5 birds showed the lowest drip lossThe results for total antioxidant activity are not similar among sampling days. In general, control group showed inferior values, but T2 and T4 had greater values on day 0 and 28. The rate of lipid peroxidation increased with time; however, EOs administration markedly reduced the peroxidation rates compared to controls. The catalase activity of breast meat was significantly declined from day fourteen, but was enhanced as an effect of essential oil consumption especially in group T5 at 21 and 28 days. . Supplementation of garlic, turmeric and cinnamon essential oils to broiler chickens increased glutathione peroxidase in breast meat on days 21 and 28, while turmeric EO enhanced superoxide dismutase upto 7 days. In conclusion, essential oils are valuable supplements for broiler chickens and potent in enhancing meat quality and prolong the shelf life.

Do Increases and Decreases in Non-renewable Energy Consumption Have the Same Effect on Growth in Türkiye?

This study examines the relationship between fossil energy consumption (FEC) and economic growth by applying the non-linear ARDL method in the Türkiye sample. This relationship was addressed in 3 different models to eliminate the multicollinearity between the oil, natural gas, and coal variables that make up the FEC. According to the analysis results, all models have an asymmetric cointegration between the variables. In all models, the effect of decreases in energy consumption on economic growth is more dominant than increases in the long run. According to the causality results, the neutrality hypothesis is valid for coal consumption, the feedback hypothesis is valid for natural gas consumption, and the growth hypothesis is valid for oil consumption.

Efficient oil–water emulsion separation using chitosan hydrogel-coated aluminium electrodes

Abstract The escalating consumption of crude oil, driven by rapid industrialization, poses a significant threat to terrestrial and marine ecosystems. Addressing the treatment of oily wastewater is imperative, given the environmental consequences and the loss of oil feedstock. Methods such as centrifugation, gravity separation, and chemical–physical membrane separation have limitations in handling stable emulsions, especially microemulsions present in water. In this study, we present an innovative approach utilizing electricity for the coagulation process. Electrocoagulation is employed, and the resulting oil particles are efficiently removed through low-tech physical methods such as sedimentation and filtration. To enhance efficiency and reusability, we introduce chitosan hydrogel-coated aluminium electrodes in the electrocoagulation process. The research demonstrates remarkable success, achieving a 99% efficiency in separating artificial oil–water emulsions. Optimal separation (95.85%) is achieved at a 10 mm inter-electrode distance, and efficiency increases with higher oil content, longer electrocoagulation time (up to 99.15% at 60 min), and increased voltage (up to 85% at 50 V). The chitosan-coated electrodes offer a sustainable and cost-effective solution by improving reusability and mitigating the need for frequent changes. These findings underscore the significance of electrocoagulation, particularly with chitosan-coated aluminium electrodes, as an efficient and eco-friendly method crucial for addressing oil removal in industrial processes.
