Enhancing power quality in solar-grid integrated systems with ANFIS-based control using split source inverters

Power generation and renewable energy consumption benefit greatly from integrated solar grid systems. However, the intermittent nature of solar electricity and potential voltage swings might raise power quality concerns when solar energy is integrated with the grid. The benefits of the split-source inverter architecture include higher efficiency, lower harmonic distortion, and the ability of power flow in both directions. The ANFIS controller improves the control parameters of the single-stage split-source inverter, eliminating power quality issues including voltage fluctuations, harmonics, and reactive power variations. These difficulties can negatively affect the overall quality of power. ANFIS-based control of the solar-grid integrated system guarantees optimal power conversion, precise voltage management, and higher power quality by intelligently altering the control settings. ANFIS solar electricity and potential voltage swings might raise power quality concerns when solar energy is integrated with the grid. Using an Adaptive Neuro-Fuzzy Inference System (ANFIS)- based control with split source inverters, this research provides a unique method to improve power quality in solar-grid integrated systems. The benefits of the split-source inverter architecture include higher efficiency, lower harmonic distortion, and the ability for power to flow in both directions. The ANFIS controller improves the control parameters of the single-stage split-source inverter, eliminating power quality issues including voltage fluctuations, harmonics, and reactive power variations. These difficulties can negatively impact the power's overall quality. ANFIS-based control of the solar-grid integrated system dynamically adjusts the voltage and current waveforms in response to variations in solar irradiation and grid circumstances. The simulation results show that the harmonic distortion is lowered, voltage stability is enhanced, and reactive power is managed more effectively.

Research on Multi-Objective Optimization Model of Industrial Microgrid Considering Demand Response Technology and User Satisfaction

In the process of wind power, coal power, and energy storage equipment participating in the operation of industrial microgrids, the stable operation of wind-storage industrial microgrids is guaranteed by considering demand response technology and user satisfaction. This paper firstly sorts out the status quo of microgrid operation optimization, and determines the main requirements for user satisfaction considering three types of load characteristics, demand response technology, power consumption benefit loss, user balance power purchase price and wind power consumption evaluation indicators in the system. Secondly, the operation architecture of the windstorage industrial microgrid is designed, and the multi-objective optimization model of the wind-storage industrial microgrid is established with the comprehensive operating cost and user satisfaction as the target variables, and the corresponding solution method is mentioned. Finally, a typical wind-storage industrial microgrid is selected for simulation analysis, and the results show that, (1) Considering the demand response technology, the comprehensive operating cost of the wind-storage industrial microgrid per day is 5292.63 yuan, the user satisfaction index is 0.953, and the wind power consumption rate reaches 100%. (2) By setting four scenarios, it highlights that the grid-connected operation mode is superior to the off-grid operation mode. Considering the demand response technology, the load curve can be optimized, and the time-of-use electricity price can be fully used to coordinate the operation of each unit, which enhances the wind power consumption capacity. The compromise solution of the system comprehensive operating cost and user satisfaction under the confidence level of 0.95 is obtained, namely (5343.22, 0.94). (3) The frontier curve shows that in the process of model solving, it is impossible to optimize any sub-objective by changing the control variables, which proves that there is a close relationship between the comprehensive operating cost of the system and the confidence level, which can provide effective guidance for the optimal operation of industrial microgrids.

Nutritional Benefits of Fish Consumption for Humans: A Review

In conquest to attain the goal of zero hunger as well as tackling the problem of malnutrition worldwide, fish proves to be one of the best functional food to humans. Along with the sense of good taste to humans, it ensures great nutritional value at an affordable price. Fish food plays an active role in providing nutrients to the body that are directly involved in metabolic activities. It is enriched with high quality protein containing all the essential amino acids, omega-3 polyunsaturated fatty acids including eicosapentanoic acid and docosahexaenoic acid. Also, it provides wide variety of micronutrients involving vitamins (fat soluble vitamins and several members of vitamin B complex) and minerals. Also, these have significant protective effects against the occurrences of several diseases such as cancer, cardiovascular diseases, inflammatory diseases, retinopathy, diabetes, arthritis and some other acute or chronic diseases. The bioactive peptides from fish food are reported for their positive effect on humans. Therefore, fish is an optimal choice of food to humans as it helps in their growth, development and maintenance of good health. However, care should be taken during processing of fish or fish products as the inappropriate handling can deteriorate the nutritional quality of the food.

Features of Non-Alcoholic Beer on Cardiovascular Biomarkers. Can It Be a Substitute for Conventional Beer?

Numerous studies have revealed the beneficial effects of moderate beer consumption on cardiovascular diseases. However, the presence of alcohol in beer can represent a matter of concern, since alcohol intake poses a risk to some individuals. Additionally, adults who are life-long abstainers should not be encouraged to consume alcohol for health purposes. Consequently, the benefits of beer consumption remain a controversial issue. In this scenario, the present review gathers the reported information concerning the cardiovascular effects of non-alcoholic beer, and makes a comparison between these effects and those of conventional beer. Despite the scarcity of published results to date describing the effects of non-alcoholic beer consumption, the available literature indicates that it is more effective than conventional beer in preventing oxidative stress (lower lipid and protein oxidation), preserving the endothelial function (lower endothelial dysfunction) and inhibiting thrombogenic activity (lowered oxidized LDL). By contrast, conventional beer has shown to induce greater increases in HDL-cholesterol levels (known as a cardiovascular protective factor) compared to non-alcoholic beer. This effect cannot be solely attributed to alcohol content, since the polyphenol content in conventional beer tends to be higher than that found in non-alcoholic beer.

Potential Benefits of Lycopene Consumption: Rationale for Using It as an Adjuvant Treatment for Malaria Patients and in Several Diseases.

Malaria is a disease that affects thousands of people around the world every year. Its pathogenesis is associated with the production of reactive oxygen and nitrogen species (RONS) and lower levels of micronutrients and antioxidants. Patients under drug treatment have high levels of oxidative stress biomarkers in the body tissues, which limits the use of these drugs. Therefore, several studies have suggested that RONS inhibition may represent an adjuvant therapeutic strategy in the treatment of these patients by increasing the antioxidant capacity of the host. In this sense, supplementation with antioxidant compounds such as zinc, selenium, and vitamins A, C, and E has been suggested as part of the treatment. Among dietary antioxidants, lycopene is the most powerful antioxidant among the main carotenoids. This review aimed to describe the main mechanisms inducing oxidative stress during malaria, highlighting the production of RONS as a defense mechanism against the infection induced by the ischemia-reperfusion syndrome, the metabolism of the parasite, and the metabolism of antimalarial drugs. Furthermore, the effects of lycopene on several diseases in which oxidative stress is implicated as a cause are outlined, providing information about its mechanism of action, and providing an evidence-based justification for its supplementation in malaria.

A red wine intervention does not modify plasma trimethylamine N-oxide but is associated with broad shifts in the plasma metabolome and gut microbiota composition

Gut microbiota profiles are closely related to cardiovascular diseases through mechanisms that include the reported deleterious effects of metabolites, such as trimethylamine N-oxide (TMAO), which have been studied as diagnostic and therapeutic targets. Moderate red wine (RW) consumption is reportedly cardioprotective, possibly by affecting the gut microbiota. To investigate the effects of RW consumption on the gut microbiota, plasma TMAO, and the plasma metabolome in men with documented coronary artery disease (CAD) using a multiomics assessment in a crossover trial. We conducted a randomized, crossover, controlled trial involving 42 men (average age, 60 y) with documented CAD comparing 3-wk RW consumption (250mL/d, 5 d/wk) with an equal period of alcohol abstention, both preceded by a 2-wk washout period. The gut microbiota was analyzed via 16S rRNA high-throughput sequencing. Plasma TMAO was evaluated by LC-MS/MS. The plasma metabolome of 20 randomly selected participants was evaluated by ultra-high-performance LC-MS/MS. The effect of RW consumption was assessed by individual comparisons using paired tests during the abstention and RW periods. Plasma TMAO did not differ between RW intervention and alcohol abstention, and TMAO concentrations showed low intraindividual concordance over time, with an intraclass correlation coefficient of 0.049 during the control period. After RW consumption, there was significant remodeling of the gut microbiota, with a difference in β diversity and predominance of Parasutterella, Ruminococcaceae, several Bacteroides species, and Prevotella. Plasma metabolomic analysis revealed significant changes in metabolites after RW consumption, consistent with improved redox homeostasis. Modulation of the gut microbiota may contribute to the putative cardiovascular benefits of moderate RW consumption. The low intraindividual concordance of TMAO presents challenges regarding its role as a cardiovascular risk biomarker at the individual level. This study was registered at clinical trials.gov as NCT03232099.

Do Beliefs about Alcohol and Cancer Risk Vary by Alcoholic Beverage Type and Heart Disease Risk Beliefs?

Alcohol is a leading risk factor for cancer, yet awareness of the alcohol-cancer link is low. Awareness may be influenced by perceptions of potential health benefits of alcohol consumption or certain alcoholic beverage types. The purpose of this study was to estimate awareness of the alcohol-cancer link by beverage type and to examine the relationship between this awareness and concomitant beliefs about alcohol and heart disease risk. We analyzed data from the 2020 Health Information National Trends Survey 5 Cycle 4, a nationally representative survey of U.S. adults. Awareness of the alcohol-cancer link was highest for liquor (31.2%), followed by beer (24.9%) and wine (20.3%). More U.S. adults believed wine (10.3%) decreased cancer risk, compared with beer (2.2%) and liquor (1.7%). Most U.S. adults (>50%) reported not knowing how these beverages affected cancer risk. U.S. adults believing alcoholic beverages increased heart disease risk had higher adjusted predicted probabilities of being aware of the alcohol-cancer link (wine: 58.6%; beer: 52.4%; liquor: 59.4%) compared with those unsure (wine: 6.0%; beer: 8.6%; liquor: 13.2%), or believing alcoholic beverages reduced (wine: 16.2%; beer: 21.6%; liquor: 23.8%) or had no effect on heart disease risk (wine: 10.2%; beer: 12.0%; liquor: 16.9%). Awareness of the alcohol-cancer link was low, varied by beverage type, and was higher among those recognizing that alcohol use increased heart disease risk. These findings underscore the need to educate U.S. adults about the alcohol-cancer link, including raising awareness that drinking all alcoholic beverage types increases cancer risk.

Promoting Protein Intake in an Ageing Population: Product Design Implications for Protein Fortification

Protein is a macronutrient of interest for an ageing population and intake requirements increase with age. Accordingly, protein is often fortified into products for older adults to help alleviate malnutrition and impede sarcopenia. However, more emphasis needs to be placed upon designing protein-fortified products to ensure suitability for older adults. This study involved a two-stage approach: (1) an initial review of products commonly fortified with protein and (2) two questionnaires for younger and older adults (n = 73; 18-30; 65+) to investigate optimal portion sizes (drinks and cakes) as well as attitudes, consumption habits and preferences towards protein fortification. The initial literature and market review demonstrated protein-fortified products are typically in liquid or snack format; however, there is considerable variability in terms of product types, serving size and protein sources. There were no age-related differences found for ideal cakes portion size whereas there were for liquids. Older adults are typically not consuming protein-fortified products; therefore, more importance should be placed on the consumption moment (breakfast or as snacks between meals) and on cereals, pasta, porridge, cakes, and biscuits. Older adults need increased awareness of, and more education on, the benefits of protein consumption, coupled with products tailored and designed to encourage intake.

DESIGN OF LOW POWER HIGH SPEED CNTFET ADDER SUBTRACTOR

Multi-valued logic design itself is not sufficient to achieve the performance improvement in digital system design in nanotechnology. The need to replace silicon devices with some more efficient new devices are required so as to meet the power improvements in the nanoscale region. Among various devices explored, CNTFET is the most promising alternative to replace conventional MOS transistors. These nano devices have the benefits of low power consumption due to reduced leakage component, ballistic transport operation even at low supply voltages makes them suitable for high frequency and low voltage applications. MVL circuitry has soared in popularity because the threshold voltage of the CNFET device is somewhat adjustable by the diameter of carbon nanotubes. CNFET is used for high performance, high stability and low-power circuit designs as an alternative material to silicon in recent years. Carbon Nanotube Filed-Effect Transistor (CNFET) is one of the promising alternatives to the MOS transistors. The geometry- dependent threshold voltage is one of the CNFET characteristics, which is used in the proposed design. In this paper, we present a novel high speed Adder-subtractor cell using CNFETs based on XOR gates and multiplexer. Proposed design uses fourteen transistors, ten for full adder and four to modify the cell for subtraction. Simulation results show significant improvement in terms of delay and area saving with respectively compared to the latest design. Simulations were carried out using HSPICE based on CNFET model with optimized design parameters. All designs are simulated at 32nm CNFET with HSPICE. The simulation results show that on average, speed enhancement and area saving of 48% and 11% can be achieved with optimized parameters design over default values of these parameters. The cumulative benefits of the novel adder-subtractor design based CNFET result in an PDP reduction by a factor of 41%.

Association between Intake of Fermented Dairy Product and Diet Quality, Health Beliefs in a Representative Sample of Polish Population

This study aimed to evaluate the association of diet quality and perception of consumption benefits with intake of fermented dairy products in a representative sample of the Polish population. The study was carried out in February 2020 and involved 2009 men and women randomly sampled from the representative Polish population stratified into two age groups (19-30 and 66-75 years). Dairy product intake was evaluated using a qualitative food frequency questionnaire. Diet quality was assessed by calculating the Mediterranean Diet Adherence Screener (MEDAS) score. The perceived health benefit of dairy product consumption was assessed by a literature-based questionnaire. The Health Concern Scale was used to measure participants' attitudes toward health. The median intake of fermented dairy products was 0.8 portion/day (IQR: 0.4-1.6). Intake of fermented dairy products was associated with a higher MEDAS score. We observed that people with the highest intake of fermented dairy products consumed more oils, vegetables, wine, legumes, fish and seafood, sweets and pastries, nuts, had a higher preference for white meat and were more likely to report their perceived benefits to maintain body weight, reduce cardiovascular risk, and improve immune and dental health. Moreover, a high intake of fermented dairy products was positively related to paying more attention to health. Our study identified patterns of health behaviors associated with the frequent consumption of fermented dairy products. We observed that the intake of fermented dairy products is associated with better diet quality, consumer self-consciousness, and a greater attitude toward personal health.

Mulethi (licorice): real but unrecognised hazards of superstitions in mothers: a case report

Licorice extract has long been known as a natural sweetener and thirst reliever. Many people who take large amounts and are prone to complications overestimate its nutritional benefits. Glycyrrhetic acid, the active metabolite in licorice, inhibits 11-ß-hydroxysteroid dehydrogenase enzyme type 2 causing increased cortisol levels and hypernatremia, hypokalemia. In this case report, we ensure a holistic study of licorice, as well as the documented side effects of excessive consumption. The study emphasises the necessity of looking into dietary habits and herbal medicines that are utilised around the world based on cultural and habitual grounds rather than scientific data. Not many case reports are available on this particular aspect of licorice consumption and its unknown adverse effects. We anticipate that our review will serve as a deterrent to parents’s superstitious beliefs on the benefits of licorice consumption.

Consumption of the cell-free or heat-treated fractions of a pitched kefir confers some but not all positive impacts of the corresponding whole kefir.

Kefir consumption can have many metabolic health benefits, including, in the case of specific kefirs, improvements in plasma and liver lipid profiles. Our group has previously shown that these health benefits are dependent on the microbial composition of the kefir fermentation, and that a pitched kefir (PK1) containing specific traditional microbes can recapitulate the health benefits of a traditional kefir. In this study we investigated how different preparations of kefir impact cholesterol and lipid metabolism and circulating markers of cardiovascular disease risk and determine if freeze-drying impacts health benefits relative to past studies. Eight-week-old male and female C57Bl/6 mice were fed a high fat diet (40% kcal from fat) supplemented with one of 3 freeze-dried kefir preparations (whole kefir, cell-free kefir, or heat-treated kefir) for 8 weeks prior to analysis of plasma and liver lipid profiles, circulating cardiovascular disease (CVD) biomarkers, cecal microbiome composition, and cecal short-chain fatty acid levels. These groups of mice were compared to others that were fed a control low-fat diet, control high fat diet or high fat diet supplemented with milk, respectively. All kefir preparations lowered plasma cholesterol in both male and female mice, while only whole kefir lowered liver cholesterol and triglycerides. Plasma vascular cell adhesion molecule 1 (VCAM-1) was lowered by both whole kefir and heat-treated kefir in male mice but not females, while c-reactive protein (CRP) was unchanged across all high fat diet fed groups in males and females. These results indicate that some of the metabolic benefits of consumption of this kefir do not require whole kefir while also indicating that there are multiple compounds or components responsible for the different benefits observed.

Low alcohol consumption influences outcomes in individuals with alcohol-related compensated cirrhosis in a French multicenter cohort

The harmful impact of heavy alcohol consumption and recurrence in patients with alcohol-related cirrhosis is long-established, although this is based on old studies. However, the drivers of long-term outcome still need to be clearly investigated. All patients with biopsy-proven compensated alcohol-related cirrhosis included in the CIRRAL cohort (22 centers) were prospectively studied. Prognostic variables of survival and liver event-free survival were assessed using multivariable Cox models with stepwise selection. The prognostic impact of alcohol recurrence during follow-up (computed in glass-years in the same way as pack-years for tobacco) was assessed using a time-dependent covariable. From 2010 to 2016, 650 patients were included. The median age at baseline was 58.4 years, 67.4% were men and the median BMI was 27.8kg/m2, 63.8% had a history of liver decompensation, and 70.2% had discontinued alcohol. At 5 years, recurrence occurred in 30.9% of abstinent patients and this risk was higher in patients with a history of drug abuse and in those with shorter alcohol discontinuation times. Median survival was 97 months. Age, alcohol consumption at baseline, platelet count and Child-Pugh score >5 were associated with overall and liver event-free survival on multivariate analysis. Alcohol consumption of more than 25 glass-years during follow-up was independently associated with lower survival and with a trend toward lower liver event-free survival, with the risk increasing from 1 glass-year, though not significantly. Simon & Makuch plots confirm the benefit of no alcohol consumption (<1 glass/week) on both outcomes and the dose-dependent impact of alcohol over time. This prospective study in patients with compensated alcohol-related cirrhosis identifies factors predictive of alcohol recurrence during follow-up and shows that moderate alcohol consumption during follow-up negatively impacts outcomes. Patients with alcohol-related cirrhosis should be advised to completely stop drinking alcohol. CIRRAL (NCT01213927) cohort was registered at ClinicalTrials.gov and the full protocol is available at the following link: https://clinicaltrials.gov/ct2/show/NCT01213927. In patients with alcohol-related cirrhosis, data are lacking about the impact of the amount of alcohol consumed on both survival and liver-related events. The present study based on the CIRRAL cohort demonstrates that alcohol recurrence occurs in more than 30% of patients with compensated cirrhosis and that even a moderate recurrence strongly influences outcomes. Patients with compensated alcohol-related cirrhosis should be advised to completely discontinue alcohol consumption, even in small amounts, as the present study shows that no alcohol consumption can be regarded as safe when cirrhosis has developed.

Peningkatan Pengetahuan Ibu PAUD tentang Gizi Seimbang dan Pentingnya Konsumsi Sayur dan Buah di Desa Sukanagalih, Cianjur

Cianjur is potential province for vegetables and fruit commodities compared to other Java provinces. Despite abundant crop production, stunting prevalence among under-five is high, while the dietary diversity score was low. To prevent and overcome nutritional problems, a strategy is required to improve dietary diversity consumption patterns. The participant in this community service activity in Sukanagalih Village, Cianjur mothers, and students of PAUD. Participants are expected to gain more knowledge about the benefits of fruit and vegetable consumption and balanced diet. Further, it would enhance their motivation to utilize the home yard to grow vegetables and fruit. The activities are nutrition education in the classroom about the nutritional value in my plate, guidelines for balanced diet, and the adequacy of vegetables and fruit, continue with seed planting activities, and games. The number of participants in this activity is 22 pairs of mothers and children. Data analysis on nutrition knowledge scores of mothers was using the Wilcoxon signed rank test. The results showed that 59% of mothers experienced increased nutrition knowledge. The median mother's knowledge score on the pre-test was 64.3 ± 15.8 and the post-test was 71.4 ± 9.9 with a p-value &gt; 0.05. This shows that nutrition education for short duration is not sufficient to increase the mother's knowledge. The enthusiasm of mothers and students in participating in counseling and planting seeds activities is very high. However, longer duration and frequency of activities and the use of local languages are necessary for more significant result.

An updated review of published human health risk-benefit assessment studies in the scientific literature

Background: Public health policies in the area of food and diets tend to separate recommendations on food safety and nutrition. However, food products can simultaneously have risks and benefits. Risk-benefit assessment (RBA) seeks to integrate the assessment of both risks and benefits to aid complex decision-making using a multidisciplinary approach. In this study, a systematic literature review of recent RBA studies was performed, focusing on food consumption and human health following earlier reviews by Boué, et al. (2015) and Thomsen, et al. (2021). Results: A total of 50 new RBA studies were reviewed since 20 May 2014. Our current literature review shows that the majority of RBA studies conducted in recent years remain focused on seafood, with studies on fish alone comprising 34% of all studies; the focus being on the benefits of fish consumption versus contaminant exposure. Most of the studies have been conducted in Europe (n = 31) and Asia (n = 11). Conclusion: RBA has the potential to be applied more widely to other food choices such as alternative proteins, yet application remains limited to specific applications and contaminant/nutrient case studies. In recent years, a few RBA studies have been reported on less mainstream food sources and one specifically on novel foods. Novel foods offer a unique application space for RBA as their development is focused heavily on the benefits to the consumer, society, and environment, yet there remains uncertainty as to their safety.

THE CONTENT AND FOCUS OF BRAND COMMUNICATIONS IN THE UKRAINIAN ORGANIC MARKET

Purpose. The purpose of this article is to study the implementation of brand communications in the Ukrainian organic market as represented in social media. Design/methodology/approach. The materials of the research are marketing (text) messages contained on the official Facebook pages of two certified Ukrainian organic egg producers. Marketing messages were collected for the period from February 31, 2018 to December 29, 2021 (or about 3 years) and studied based on the theoretical principles of brand communication in social media in the organic market and using the quantitative method of corpus linguistics (employing corpus analysis toolkit AntConc software for text analysis). Corpus linguistics helps to reveal objective, quantitative relationships between words, and their frequency in text messages on the official Facebook pages of organic egg producers, that is making it possible to uncover the main focus of these messages. Findings. The results of the study show that the content of brand communications is based on the multifaceted value of organic products, as indicated by the use of a set of motives in marketing messages that may encourage Ukrainian consumers to be inclined to buy organic. The focus of marketing information is primarily directed on gastronomic hedonism and is more product-centered, with the description of the benefits of egg consumption for human health. Ukrainian organic egg producers communicate the nutritional and taste characteristics of products, but not the environmental component of production, including animal care. Practical implications. The information about the chickens and their welfare is present in marketing messages, but it is not at the core of the implementation of brand communications, and therefore consumers may perceive such products as a good choice for their health, rather than ethically sound choices from the standpoint of animal welfare and care for the environment. However, according to Ukrainian scholars, the ecological dimension of organic production and organic products is a competitive advantage in the food market and the most important motive for the consumption of organic products than their hedonistic advantages. This is important both from the point of view of differentiating organic from other eco-labelled products, which compete with organic in the food market, and to teaching consumers to distinguish organic from non-organic. Thus, our recommendation to organic egg producers is to pay more attention to informing the target audience about the production certification and labelling because it will assure consumers of the high quality and unique value of organic products. Originality/value. This study fills the research gap in Ukraine by having examined the content and focus of brand communications in the Ukrainian organic market, their correspondence with the motives of Ukrainian consumers and the recommendations of scientists and practitioners in the field. This study identified not only the topics of brand communications of organic egg producers but also the focus of producers on conveying certain values to the consumer, which does not fully cover the organic values.

Joint Task Offloading and Service Caching for Multi-Access Edge Computing in WiFi-Cellular Heterogeneous Networks

Enabled by Multi-access Edge Computing (MEC) in a WiFi-cellular heterogeneous network, the tasks of mobile terminals (MTs) can be offloaded via the cellular network to the MEC servers or cloud server, or via the WiFi network to alleviate transmission congestion of the cellular network. The MEC also enables service caching to cache the programs/libraries/databases of the tasks to avoid repeated input data uploading. Existing research works lack joint optimization on the task offloading and service caching for MEC in the WiFi-cellular heterogeneous network. In this paper, a novel resource management scheme for joint task offloading and service caching is proposed to maximize the energy consumption benefits of all the MTs covered by a WiFi-cellular heterogeneous network while guaranteeing the task processing delay tolerance of each MT. We consider the constraints on limited computing and storage resources of the MEC servers equipped on the cellular base station and the WiFi access point, and we also consider cellular channel allocation for the task offloading. We design an iterative algorithm based on the alternating optimization technique to solve the proposed mixed integer nonlinear programming problem efficiently. Extensive simulations are conducted in multiple scenarios by varying different crucial parameters. The numerical results demonstrate that our scheme can largely improve the system performance in all the scenarios, and energy consumption reduction optimized by our scheme is 16.24%-43.09% higher than those by the comparative works.

Fibre Intake in Chronic Kidney Disease: What Fibre Should We Recommend?

Chronic kidney disease (CKD) is a major global health problem that challenges all patients’ healthcare needs. Fibre consumption benefits kidney patients by acting preventively on associated risk factors, improving intestinal microbiota composition or reducing metabolic acidosis and inflammation. In this review, we focus on increasing fibre consumption and the quality of fibre to recommend, in addition to increasing the consumption of foods that naturally have it in their design, that can resort to fortified foods or fibre supplements. The Western nutritional practice, which is low in fibre and rich in animal proteins, saturated fats, sodium, and sugar, increases the risk of mortality in these patients. On the contrary, patterns with higher consumption of fibre and vegetable proteins, such as the Mediterranean, vegetarian, or Plant dominant low protein diet (PLADO), seem to have a preventive effect on the associated risk factors and influence CKD progression. Until now, the use of fibre supplements has not achieved an evident impact on clinical results. Fibre-rich foods contain other nutrients that reduce cardiovascular risk. Promoting diets richer in vegetables and guaranteeing adequate energy and protein intake is a challenge for the multidisciplinary teams involved in the standard of care for CKD.

The Effects of Anthocyanins in the Treatment of Metabolic Syndrome: A Systematic Review

The present study aimed to review studies on anthocyanin consumption and its benefits in three of the parameters of the metabolic syndrome, namely total cholesterol, insulin resistance and blood pressure control. The articles were selected from the SCIELO, PubMed and Science Direct databases. The descriptors that were used in English are anthocyanin, metabolic syndrome, benefits, treatment and based on these descriptors, the following word combinations were investigated: benefits of anthocyanins in metabolic syndrime, treatment of metabolic syndrome with anthocyanins. Selected 9 studies found within the parameters sought, results were obtained in 8 articles demonstrating that anthocyanins can help reduce total cholesterol, 5 proving that beneficial actions occur in decreasing insulin resistance and 6 articles emphasized that ANTs can have effects positive regarding the decrease in blood pressure. It is common to find individuals with at least 1 of the parameters of the metabolic syndrome, the articles found show that it is possible to control and improve some of these parameters through the consumption of antioxidants such as ANTs, however there is a lack of studies relating the benefit of consumption of these antioxidants in these factors of aggravating risk for future cardiovascular problems.

System value evaluation of energy storage system in distribution networks: Theory and calculation model

With the proposal of the “carbon peak and neutrality goals”, energy storage system (ESS), as an emerging power technology, has great potential to promote the green transformation of energy in power systems. To further promote the development of the ESS industry and realize its commercialization, it is necessary to measure the multiple value that ESS brings to power systems. In this paper, the evaluation theory of system value is firstly explained, and two methods for calculating system value of ESS in power systems are proposed. Then, models for system value evaluation of ESS are established using the cumulative approximation method and the difference method, respectively. The former is the superposition of multiple value, and the latter is the difference between the value of the original system and the new system. The value benefits considered are: arbitrage benefit, network loss benefit, increased wind power consumption benefit, and emission reduction benefit. Finally, using the IEEE 33-node distribution network as a test system, the data results show that the cumulative approximation method can be applied to scenarios with fewer value domains, while the difference method is more suitable for quantitative value evaluation in the regional grid.
