Identification of Fatty Acid Content of Sargassum sp. Seaweed and Ulva sp. in Different Seasonal Conditions

The active ingredients contained in seaweed prepare for pharmaceutical, cosmetic and food supplement needs from seaweed Sargassum sp. and Ulva sp. in different seasonal conditions it is thought to have a contribution of specific active ingredients. However, the fatty acid profile and morphology of the seaweed species Sargassum sp. obtained in the dry season and rainy season had the same results as the profile of the seaweed Ulva sp. which was collected in the Bangsring Beach area, Wongsorejo District, Banyuwangi, Indonesia. This is thought to be due to the extreme differences in dry season and rainy season conditions that have not yet resulted in real or drastic changes in the composition and quantity of macro and micronutrients, water quality and active fatty acid compounds as well as the adaptability of seaweed. Fatty acids of Sargassum sp. dominated by the composition of linoleic acid (C18:2), palmitic acid (C16:0) and oleic acid (C18:1), while the fatty acids of Ulva sp. dominated by the composition of heptadecanoic acid (C17:0), pentadecanoic acid (C15:0) and linoleic acid (C18:2n6).

New Sorbents Based on Polyacrylonitrile Fiber and Transition Metal Ferrocyanides for 137Cs Recovery from Various Composition Solutions

For the first time, new sorbents based on polyacrylonitrile (PAN) fiber and transition metal ferrocyanides were obtained. The main difference between the obtained sorbents and the existing ones is the stage of preliminary preparation of the initial support by converting it into the forms PAN-Fe(OH)3 or PAN-MnO2, due to which additional ion exchange groups (carboxyl, carbonyl, etc.) are formed, which increases the amount of ferrocyanide fixed to the support. The best components and conditions for the synthesis of new sorbents were determined (concentration (0.1–0.2 mol/L), as well as pH (1 for sorbents based on PAN-Fe(OH)3, and 1–5—PAN-MnO2) of potassium ferrocyanide solution, concentration of transition metal salts (0.02 mol/L), temperature conditions). The influence of the studied solution composition (pH, concentration of Na+, K+, NH4+ ions) on the cesium distribution coefficients during its recovery by the obtained sorbents was assessed. The possibility of cesium recovery from solutions with pH 1–9 containing macro quantities of cations was demonstrated. The sorbents derived were characterized by modern structural methods such as infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy with EDS analysis. A study of the trace amount sorption of 137Cs was carried out in comparison with commercially available highly efficient sorbents (FNS-10 and Termoksid-35), and it was shown that the resulting sorbents are not inferior to industrial ferrocyanide sorbents and can be used for 137Cs selective sorption from technological solutions and natural waters.

Nutritional Composition and Odor-Contributing Volatile Compounds of the Edible Mushroom Cantharellus alborufescens.

Chanterelles are one of the most highly valued wild edible mushroom genera worldwide. This work aimed to investigate the nutritional characteristics and volatile compounds' profile of Cantharellus alborufescens for the first time. Proximate analysis was performed according to the Association of Official Agricultural Chemists, while the mineral contents and the volatile compounds were determined using ICP-MS and GC-MS, respectively. C. alborufescens had an average of 25.8% protein, 5.5% fat, 12.7% ash, and 55.9% carbohydrates, including 11.4% fiber per dw of mushroom. Further analyses of the fat and protein contents revealed high amounts of polyunsaturated fatty acids as well as monosodium glutamate-like amino acids. Linoleic acid (42.0% of fat) and oleic acid (28.6% of fat) were the major fatty acids, while leucine (1.2%) and lysine (0.9%) were the most abundant essential amino acids. The results showed that C. alborufescens contained 3.1 µg/g vitamin D2 and 4.9 mg/g vitamin E per dw, as well as notable quantities of macro- and microelements, such as potassium, calcium, magnesium, and iron. GC-MS analysis revealed various volatile compounds such as acetaldehyde, n-hexanal, 3-methylbutanal, 1-octen-3-ol, etc. In conclusion, this study supports the use of C. alborufescens as a food rich in fiber and vitamin E, with a suitable amount of protein and other nutrients.

The dynamics of macro- and microplastic quantity and size changes during the composting process

The quantity and type of macro- and microplastics was investigated in rotting material during the composting process of two state-of-the-art composting plants in Austria. Microplastics >0.2 mm, were found already after the first turning event in both facilities. The generation of microplastics was more extensive in the plant that used shorter turning intervals during the first four weeks and generated approx. 21 particles per week and kg−1 DM. After 4 weeks of operation less microplastic particles were detected, which suggested that particles were fractionated to smaller sizes during processing. In addition, a total of nine composts from three different facilities that were operated in various settlement structures were compared. 7 to 232 macro- and microplastic particles per kg DM were found, whereas the highest plastic burden was observed in the composts made from biowaste that originated from the most densely populated area.

Solvent extraction optimisation and validation of the HPLC-DAD method for quantification of 5-hydroxyindolin-2-one inProtaetia brevitarsis seulensis larvae extracts

Recent studies on the composition of edible insects have placed more emphasis on the quantity and quality of macro- and micronutrients and less emphasis on their bioactive components. This study aimed to assess the effect of 0-100% ethanol solvent ratio considering 5-hydroxyindolin-2-one (5-HI) content on the extraction efficiency inProtaetia brevitarsis seulensis larvae (PBSL) extract and to investigate the effect of PBSL on the induction of cell adhesion molecules (CAMs) in tumour necrosis factor (TNF)-α-activated human umbilical vein endothelial cells (HUVECs). A reversed-phase high-performance liquid chromatography method coupled to a diode array detector (HPLC-DAD) was validated for the quantification of 5-HI. The HPLC-DAD method was validated for its specificity, linearity, precision, accuracy, limit of detection, and limits of quantitation. The calibration curve of 5-HI showed significant linearity (R2>1). The limits of detection and quantitation were 0.016 μg/ml and 0.048 μg/ml, respectively. The relative standard deviation of the precision and intraday tests was less than 0.5%. In the recovery test, the accuracy ranged from 94.48-105.5% and the relative standard deviation value was less than 0.13%. The method validation parameters indicate the applicability of the HPLC method for quality control of food or pharmaceutical formulations containing PBSL. Comparative analysis of the 5-HI content by extraction solvent revealed that it was the highest at 357.7 μg/ml in 70% ethanol. Additionally, the analysis result of 5-HI content according to the growth conditions was the highest at 439 μg/ml at 31 °C for 30 days. Furthermore, in the condition where PBSL was at 31 °C for 30 days inhibition of the TNF-α-induced upregulation of protein expression of vascular cell adhesion molecule-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM-1), and endothelial-leukocyte adhesion molecule-1 (E-selectin) was observed. Therefore, PBSL may interfere with early atherosclerotic events involving endothelial CAM induction.

Behavior of Sheared Granular Materials at Micro-Scale during the Cyclic Loading

The aim of this paper is to explore the evolution of different micro-scale quantities during the cyclic loading using the discrete element method (DEM) for a granulate system such as sand. The numerical samples comprising of 9826 spheres were generated and consolidated isotropically using the periodic boundaries. These numerical samples were subjected to the cyclic loading for different maximum applied strains. The simulated stress-strain behavior was validated with the experiment and found an excellent agreement between them during loading and unloading. The evolutions of different micro-scale quantities were investigated in detail considering the variation of the maximum applied strain and the density of sample. It is noted that the evolution of the coordination number and the slip coordination number is a function of the maximum applied strain and the density of sample during the cyclic loading. The change of the slip coordination number is larger at the end of unloading than that at end of loading during the cyclic loading regardless of the values of the maximum applied strain and the density of sample. The ratio of strong contacts to all the contacts increases abruptly when the load is reversed, which is opposite to what is observed for the coordination number and the slip coordination number. The deviatoric fabric computed by the fabric tensor considering the strong contacts mimics the deviatoric stress irrespective of the values of the maximum applied strain and the density of sample during the cyclic loading. Moreover, a linear correlation between the macro and micro quantities exists regardless of the variation of the maximum applied strains or the variation of the density of the sample during the cyclic loading. The slopes of the lines of these correlations are almost same.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Manipulation of the black soldier fly larvae (Hermetia illucens; Diptera: Stratiomyidae) fatty acid profile through the substrate

Insects need a sufficient quantity of macro- and micronutrients in their diet for maximising their growth, development, and reproduction. To achieve high efficiency in the mass production of a particular insect species, the quality of the diet given must be considered, both in terms of its chemical (nutrients) and physical (hardness and form) characteristics. Black soldier fly (BSF),Hermetia illucens (L.) (Diptera: Stratiomyidae), is a beneficial insect widely reared due to its easy and cost-effective maintenance. An example of the end-product of BSF larvae (BSFL) is known as BSF oil, which can be used for animal feed, raw material in bar/liquid soap, and biodiesel. To obtain the best quality of oil produced from BSFL, finding an optimal substrate through diet mixing or manipulation is quite necessitated. Fatty acids with more than 18 carbons should be found in the substrate to be absorbed into the fat of BSFL to obtain a high-quality oil. There is a positive correlation between the fatty acid concentration in the substrate and the concentration in BSFL, that the concentration in BSFL is influenced by the concentration in the substrate. This emphasises the importance of the substrate’s fatty acid content in incorporating these fatty acids into BSF oil. Although the oils produced by the insect are especially high in medium-chain fatty acids and monounsaturated fatty acids, yet, to produce on such a large scale requiring further investigations.

Discovery of New Terms Associated with the Navier-Stokes Momentum Balance Equation and Finding the Evidence of Its Inapplicability to Govern Fluid Flow in the Infinite Space

Our modeling fluid flow, especially if the fluid is referred to as a gas, is established on mimicking each particle/molecule’s movement and then gathering that movement into macro quantities characterizing the fluid flow. It has resulted in discovering a new principle of the property (mass, momentum, and energy) balance in space. We named it the Ballistic Principle of the Property Balance in Space as described earlier in our publications. This paper uses a different scheme of defining a net rate of total property efflux than our original paper. Using this scheme, we formulated integro-differential forms of mass balance and momentum balance equations adapted to the incompressible fluid flow (gas flow with a mass-flow velocity less than 0.3 Ma) at the non-uniform temperature in the infinite gas space. We also investigated the analytical behavior of the integro-differential equations in the region bounding the point of singularity by applying the Taylor series expansion method to transform the integro-differential mass and momentum balance equations into the corresponding vector differential equations. Then we compared them with the Navier-Stokes equations of mass and momentum conservation for an incompressible fluid. We were surprised to find that the Navier-Stokes momentum balance equation does not describe the fluid flow adequately. Particularly, it does not consider the momentum associated with the part of velocity acquired by each gas particle during its free path traveling in the body force field. Also, the Navier-Stokes momentum balance equation is silent about the influence of the temperature non-uniformity on the momentum balance. Finally, we have demonstrated that the Navier-Stokes equations are not applicable to govern fluid flow on R3 × [0, ∞).

Significant impact of seasonality, verticality and biofilm on element accumulation of aquatic macrophytes

Submersed macrophytes accumulate large amounts of macro- and trace elements from the environment and, therefore, are frequently used as indicators of water pollution and tools to remove pollutants from contaminated waters. This study provides evidences that the quantity of macro- and trace elements accumulated in the macrophyte Ceratophyllum demersum depends strongly on the seasonality, on the vertical position of the plant material and on the biofilm cover. Element contents of macrophytes with and without biofilm cover and that of vertical plant sections were investigated by an ICP-MS technique in three different habitats, at the beginning and at the end of the vegetation period. Results demonstrated that the element concentrations of Ceratophyllum demersum dropped to one-half and one-eighth by the end of the summer; and the amount of certain elements in the lower part of plants were up to six times higher than in the upper and in plants with well-developed epiphytic microbial community 2-5-fold higher than in plants without biofilm.These results help in phytoremediation practice and in setting up future biomonitoring studies. When it is necessary to calculate the exact amount of elements which can be accumulated by plants in a polluted environment or should be removed from a contaminated water by harvesting macrophytes, it is of high importance to consider the month of the study, the plant parts harvested and the biofilm cover.

Human milk feeding and cognitive outcome in preterm infants: the role of infection and NEC reduction

BackgroundBreast milk has been associated with lower risk of infection and necrotising enterocolitis (NEC) and improved long-term cognitive outcomes in preterm infants but, if unsupplemented, does not meet the nutritional requirements of preterm infants.MethodsPreterm infants were randomised to receive a high nutrient intervention diet: preterm formula (PTF) or the standard diet: term formula (TF) or banked donor breast milk (BBM), either as their sole diet or as supplement to maternal breast milk (MBM). IQ tests were performed at ages 7, 15, 20, and 30 years.ResultsAn increase in MBM and BBM intake was associated with a lower chance of neonatal infection/NEC. Neonatal infection/NEC was associated with lower Full Scale IQ (FSIQ) and Performance IQ (PIQ) score at ages 7 and 30 years. The relationship between higher intake of MBM and PIQ at age 7 years was partly mediated by neonatal infection/NEC. The intervention diet was associated with higher Verbal IQ (VIQ) scores compared to the standard diet. There was no evidence that these effects changed from childhood through to adulthood.ConclusionsNeonatal diet is an important modifiable factor that can affect long-term cognitive outcome through a ‘human milk’ factor, protecting against infection/NEC, and a ‘nutrient content’ factor.ImpactThis is the first study to demonstrate the effects of neonatal infection/necrotising enterocolitis (NEC) on IQ in the same cohort in childhood and adulthood.Diet can be a key factor in long-term cognitive outcome in people born preterm by preventing neonatal infection/NEC and providing adequate nutrients.Human milk, whether MBM or BBM, is associated with a reduced risk of infection/NEC.A higher nutrient diet is associated with better cognitive outcome in childhood.Performance IQ is particularly vulnerable to the effects of infection/NEC and verbal IQ to the quantity of (macro)nutrients in the diet.

A case study of fly ash utilization for enhancement of growth and yield of cowpea (Vigna unguiculata L.) to sustainable agriculture

Fly ash (FA) is a coal combustion by-product of brick kiln, thermal power and incineration plants operated either based on coal and biomass or industrial solid waste. It creates environmental problems attached with their unfair utilization and problems of disposal. The growing of environmental awareness and increasing energy and material requirement will foster recycling. The Ministry of Environment, Forest and Climate Change (MoEF&CC) and Pollution Control Board (CPCB) have prepared guidelines for utilization of FA in agriculture as soil ameliorant and modifier. Recycling will promote reuse of precious materials which would otherwise be wasted and alleviate energy consumption and greenhouse gas emissions from extraction and processing. FA has potential to serve as fertilizer for improving the soil textures at optimum amount. The main purpose of this work was to use the pollutant as fertilizer. Present work was done to study the effect of FA on some biochemical and morpho-physiological properties and yield of V. unguiculata. From the obtained results after statistical analysis of data, it can be evinced that the use of FA in lower amount (25 g/m2) has sufficient quantity of macro- and micro-nutrients, which appear to be useful for the plant growth and yield of V. unguiculata, but higher amount (50, 100 g/m2) of FA showed detrimental impact on plant. The low concentration of FA improves the structure, texture of the soil which enhances the fertility of soil. So, FA can be used as a fertilizer for the enhancement of growth and yield of cow pea.

Mineral composition of raw and marinated-cooked arms from Pacific giant squid (Dosidicus gigas).

Background/aim: Shellfish consumption is often perceived as a potential health hazard due to the accumulation of toxic metals. The mineral content was investigated in marinated-cooked giant squid (Dosidicus gigas) arms from three Eastern Pacific fisheries (Peru, Chile and Benthic) to elucidate their contribution to daily recommended intakes and possible presence of pollutants. Material and methods: Thirty macro- and microminerals were analysed in the raw material, marination solution, cooking broth and cooked product. Results: Both raw and marinated-cooked squid arms contained nutritionally relevant quantities of essential macro- (Na and Mg) and microminerals (Cr, Zn, Mn and Se). Fishery origin led to minor variations in the mineral composition of raw arms, while marinated-cooked arms of Benthic origin had a higher retention of Na and juice likely due to their greater size. Levels of Pb, Hg, Zn or As found in the ready-to-eat product were below tolerable upper intake levels. Conclusion: The mineral content found in the raw squid arms suggests that the Pacific fisheries concerned are not affected by human polluting activities. Marinated-cooked squid arms cover a part of the dietary requirements for minerals and can be consumed without apparent negative nutritional implications.

Limited Risk Sharing and International Equity Returns

ABSTRACTLimited stock market participation can potentially explain the disconnect between international asset prices and macro quantities. An incomplete markets model in which risk sharing for stockholders is high generates highly correlated equity returns and relatively smooth exchange rates. Risk sharing for nonstockholders is limited because of their nonparticipation in stock markets and borrowing constraints, reducing the aggregate consumption correlation and the correlation between aggregate consumption differentials and exchange rates. Financial integration widens the disconnect by benefiting stockholders but hurting nonstockholders. Survey data indicate that international risk sharing for stockholders is better than that for nonstockholders, consistent with the predictions.

Suitable extraction conditions for determination of total anti-oxidant capacity and phenolic compounds in Ruspolia differens Serville

Recent research on edible insects’ composition has placed more emphasis on the quantity and quality of macro- and micro- nutrients and less emphasis on their bio-active components. This study aimed at assessing the effect of four factors, namely: defatting, solvent type (ethanol, methanol and acetone), solvent concentration (50, 75 and 100%) and extraction time (15, 30, 45 and 60 minutes) on the extraction efficiency, the total anti-oxidant activity and the amount of total phenolics and total flavonoids of Ruspolia differens. It was not known if the removal of fat (defatting) would influence the total anti-oxidant activity, and the distribution of anti-oxidant compounds in the R. differens matrix. Non-defatting use of acetone and sonication for 60 minutes are associated with high anti-oxidant activity and high amounts of bio-active compounds extracted. Aqueous acetone (50%) extracts had the highest average anti-oxidant activity (87.00±2.59% RSA) while 100% acetone extracts had the highest average total phenolics (11.14±0.18 GAE/g) and average total flavonoids (3.02±0.21 QE/g) content, indicating the presence of other, possibly highly polar, bio-active compounds in R. differens.

Technology trade with asymmetric tax regimes and heterogeneous labour markets: Implications for macro quantities and asset prices

AbstractThe international diffusion of technology plays a key role in stimulating global growth and explaining co‐movements of international equity returns. Existing empirical evidence suggests that countries are heterogeneous in their attitude towards innovation: Some countries rely more on technology adoption while other countries rely more on internal technology production. European countries that rely more on adoption are also typically characterized by lower fiscal policy flexibility and higher labour market rigidity. We develop a two‐country model, in which both countries rely on R&D and adoption, to study the short‐ and long‐run effects of aggregate technology and adoption probability shocks on economic growth in the presence of the aforementioned asymmetries. Our framework suggests that an increase in the ability to adopt technology from abroad stimulates future economic growth in the country that benefits from higher adoption rates but the beneficial effects also spread to the foreign country. Moreover, heterogeneity helps to explain the differences in macro quantities and equity returns observed in the international data.

Ecotoxicological and chemical properties of the rożnów reservoir bottom sediment amended with various waste materials

In the study, an attempt was made to create innovative mixtures based on bottom sediment and various types of waste to be tested for use as a substrate in the cultivation of consumer and non-consumer plants. The aim of the study was to assess the chemical and ecotoxicological properties of the growing medium prepared on the basis of bottom sediment (BS) and different carbon rich waste (cellulose waste (CW), biomass ash (BA), coffee hulls (CH), and sludge from water treatment (SW)) with a combination of 75% bottom sediment and 25% waste material. The mixtures had deacidifying properties, significant content of total organic carbon (TOC), the total quantities of macro- and micronutrients, and good sorption properties. The study showed a low total content of heavy metals in the mixtures. Moreover, a low share of the mobile fraction (F1) of metals indicated a low risk related to the metals mobility and potential bioavailability. The highest toxic effect was found in the mixture of bottom sediment and cellulose waste. Heterocypris incongruens was the most sensitive organism to substances present in the tested mixtures. Due to its low toxicity, the mixture of bottom sediment and water treatment sludge (BS+SW) constituted a potentially suitable substrate for its environmental application in agriculture, horticulture (for consumer crops) or land reclamation. Other mixtures exhibited valuable chemical properties (BS + BA, BS + CH BS + CW), but ended up being eco-toxic to the organisms, excluding them from agricultural or horticultural use for consumer crops. The proposed technology, which includes the production of growing medium based on the use of bottom sediment, is a promising way of transforming the sediment from a waste material to a valuable resource, thus enhancing the environmental benefits.
