The carbon footprint of alternative jet fuels produced in Brazil: exploring different approaches

Although the potential of Alternative Jet Fuels (AJF) to reduce greenhouse gases (GHG) emissions has been widely reported upon in the literature, there are still discrepancies among the results. These may be due to the different GHG accounting methods, including those used by different Low-Carbon Policies (LCPs). To have a clearer understanding of the life cycle performance of AJF, the carbon footprint of ten pathways was estimated, comprising promising feedstocks – such as soybean, palm, sugarcane, sugarcane residues, forestry residues, used cooking oil, beef tallow, and steel off-gases – and ASTM-approved technologies: Hydroprocessed Fatty Acids, Alcohol-to-Jet, and Fischer-Tropsch. Six methodological approaches were used: the attributional and the consequential life cycle assessment, as well as guidelines for the four LCPs: Renovabio (Brazil), CORSIA (aviation sector), RFS (United States), and RED II (Europe). Soybean-based pathway (24 to 98.7 gCO(2e)/MJ) had the low to no potential for reducing GHG when compared to their fossil counterparts, mainly due to land use change. Of all food-based pathways, AJF produced from sugarcane performed the best (-10.4 to 43.7 gCO(2e)/MJ), especially when power surplus was credited. AJF from palm oil could present significant GHG reduction for palm expansion in degraded pasturelands. By contrast, Fischer-Tropsch of lignocellulosic residues showed the highest potential for reducing GHG (-95% to -130%). Different from food-based pathways, the potential GHG reduction of residues-based pathways converged within a narrower range (-130% to -50%), except when residual feedstocks have to be redirected from their current economic use. It could lead to GHG emissions higher than fossil fuel.

Difficulties regulating positive and negative emotions in relation to coping motives for alcohol use and alcohol problems among hazardous drinkers

Objective: Hazardous drinking is a prevalent form of alcohol misuse. Past research has examined emotion regulation difficulties as a risk factor for hazardous drinking; however, the majority of prior studies have focused on regulation of negative emotions. Recent work has implicated difficulties regulating positive emotions in relation to alcohol misuse, yet, it is largely unknown if difficulties regulating positive emotions are significantly related to alcohol misuse outcomes after accounting for difficulties regulating negative emotions. Method: A racially diverse sample of hazardous drinkers were recruited from a university setting (75% female, M-age = 22.1, SDage = 4.0) to participate in a treatment study. Data from baseline was used in the current study. Structural equation modeling was used to evaluate relations between difficulties regulating positive and negative emotions and alcohol problems both directly and indirectly via coping motives. Results: After controlling for sex, age, and levels of negative and positive affect, positive but not negative emotion regulation difficulties were significantly associated with alcohol problems. Difficulties regulating emotions (both positive and negative), were significantly related to coping motives; each valence of difficulty was also indirectly related to alcohol problems via drinking to cope. Conclusions: Difficulties regulating emotions – both positive and negative – carry a heightened risk of engaging in coping-oriented alcohol use during drinking episodes and this maladaptive means of self regulation may explain a common pathway to experiencing alcohol-related problems. Notably, difficulties regulating positive emotions appear to offer incremental, explanatory value over and above difficulties regulating negative emotions. Such findings offer important clinical and theoretical implications.

Genetic variation in the prebiotic carbohydrate and mineral composition of kale (Brassica oleracea L. var. acephala) adapted to an organic cropping system

Kale is a nutrient-rich leafy green that is mostly grown in conventional agricultural systems. The demand for organic kale has increased in the U.S.; however, cultivars bred for conventional production are not suited to organic production in terms of yield and nutritional quality. The objective of this study was to evaluate the genetic variation in biomass, prebiotic carbohydrates, and minerals of 18 commercial cultivars and 35 PI accessions of kale adapted to the organic system. Significant genetic variation in both prebiotic carbohydrates and minerals was noted in both kale cultivars and PI accessions. In the kale cultivars, leaf biomass ranged from 41.4-271.2 g/plant, with kale cultivar Frizzy Joe being the highest and Fizz the lowest. A single 100-g serving from these kale cultivars provides mineral micronutrients (20-314 mg K; 95-539 mg Ca; 20-67 mg Mg; 13-87 mg P; 0.4-3.1 mg Fe; 0.3-0.9 mg Zn; 0.4-1.9 mg Mn; 20-1030 mu g Cu; and 0-940 mu g Se) and prebiotic carbohydrates, including sugar alcohols (1.7-26.9 mg), simple sugars (0.03-334 mg), and raffinose and fructooligosaccharides (0-11.2 mg). Compared to the commercial cultivars, the kale accessions had higher concentrations of minerals, except for magnesium (Mg) and manganese (Mn), and prebiotic carbohydrates, except for sucrose and verbascose + kestose. In the commercial cultivars, heritability estimates for prebiotic carbohydrates and minerals were relatively low except for sugar alcohols, Mg, and zinc (Zn). In the kale accessions, heritability estimates of glucose, fructose, potassium (K), and selenium (Se) were high. Overall, significant genetic variation exists among kale commercial cultivars and germplasm for prebiotic carbohydrates and minerals, indicating the nutritional quality of kale in organic production can be further improved by germplasm selection.

Preventing E-cigarette use among high-risk adolescents: A trauma-informed prevention approach

Exposure to childhood trauma increases the risk of tobacco use during adolescence. Recent studies have also reported potentially increased vulnerabilities to electronic cigarette (e-cigarette) use among youth with a history of childhood trauma. While empirical evidence supporting the relationship between childhood trauma and adolescent e-cigarette use is emerging, few effective preventive interventions are available to curb e-cigarette use among adolescent victims of childhood trauma. This article reviews current evidence with respect to how childhood trauma could increase risk for nicotine dependence and e-cigarette use in adolescent populations. Furthermore, this paper describes the development, design, and implementation of Rise Above (RA), a randomized, controlled trial of a trauma-informed, e-cigarette preventive intervention. Lessons learned are also discussed, including the challenges of implementing evidence-informed prevention work within communities vulnerable to traumatic events.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3452-97-9 help many people in the next few years. Safety of 3,5,5-Trimethylhexan-1-ol.

Nanoimprint assisted free standing porous vanadium oxide nanosheet based ammonia sensor

Artificial intelligence in healthcare sector endures a largest share in non-invasive and point-of-care disease diagnosis by interfacing human behaviour through wearable pathway. In a view to develop sensing element for wearables, the concept of free standing poly-1-lactic acid (PLLA)/V2O5 nanosheets using sacrificial layer – (poly vinyl alcohol- PVA)method has been proposed in this work and the studies on ammonia (NH3) sensing has been briefly discussed. In a view to enhance the sensing performance of vanadium pentoxide (V2O5) film, surface modified PLLA substrates using nanoimprint lithography (NIL) have been implemented. The V+5 stoichiometry of the free standing PLLA/V2O5 films were confirmed using x-ray photoelectron spectroscopy (XPS). From field emission scanning electron microscopy (FE-SEM), it was observed that the patterned structure of about similar to 250 nm diameter was uniformly distributed on the surface of PLLA/V2O5 film. The chemiresistive sensing studies proved that the sensor response of V2O5 films on patterned PLLA substrate exhibited enhanced response about similar to 17 towards 75 ppm than the V2O5 film on unpatterned PLLA substrate. We believe that this strategy of patterned free standing PLLA/V2O5 nanosheets will help in fabricating the wearable sensors with better sensing performance.

Effective remediation of cadmium and zinc co-contaminated soil by electrokinetic-permeable reactive barrier with a pretreatment of complexing agent and microorganism

The combination of electrokinetic-permeable reactive barrier (EK-PRB) is considered as a promising technology for the remediation of heavy metal contaminated soils. In this study, considering the convenient operation and recycling, a new sheet PRB material of sodium alginate/polyvinyl alcohol/attapulgite was prepared and characterized using scanning electron microscopy, X-ray diffraction and fourier transform infrared spectra. Subsequently, the effect of a pretreatment of citric acid (CA) and Shewanella oneidensis (MR-1) on zinc (Zn (II)) and cadmium (Cd (II)) removal from soils by EK-PRB was investigated. Results showed that Zn (II) and Cd (II) gradually migrated from anode to cathode in electric field within 8 days’ EK-PRB remediation. The simultaneous addition of CA and MR-1 resulted into the highest electric current, the lowest pH and the more negative soil zeta potential. Correspondingly, the highest removal efficiency of Zn (II) and Cd (II) also occurred in CA + MR-1 group. The new sheet PRB material effectively captured Zn (II) and Cd (II) from soils, and the most adsorption occurred in CA + MR-1 group: 1108.36 mg/kg Zn (II) and 53.84 mg/kg Cd (II) nearby the cathode after 8 days’ remediation. Specifically, for both Zn (II) and Cd (II), the CA + MR-1 group showed the greatest reduction in exchangeable and carbonate fractions and the highest increase in Fe-Mn oxidation and residual fractions. Overall, with a pretreatment of CA and MR-1, the residual Zn (II) and Cd (II) in soils were greatly reduced after EK-PRB remediation, due to the migration in the electric filed and the adsorption of the new sheet PRB material.

Interest of black carob extract for the development of active biopolymer films for cheese preservation

The aim of this work was to develop bio-based packaging materials based on black carob extracts (BCE) and kappa-carrageenan (kappa-c) blends, and to study their impact for cheese preservation. Firstly, black carob extracts were obtained with and without alcohol pre-treatment (BCE-a and BCE-b), respectively, and its chemical composition and antioxidant properties was analysed. Protein and polyphenol contents were higher in the extract without alcohol pre-treatment (BCE-b). Different bio-based films were prepared by mixing BCEs with kappa-c at different ratios, and the morphological, thermal, mechanical and water barrier properties of the films were evaluated. The antioxidant efficacy of BCE:kappa-c films prepared with both BCE extracts was further compared when applied on the preservation of cheese slides. Results showed that skipping the ethanolic extraction pre-treatment gave rise to more ductile films due to the presence of sucrose and other small sugars or the higher protein content in the BCE-b extract, which could have a plasticizer effect on the biopolymer network. Mixtures with kappa-c increased the rigidity of the films. A good correlation between barrier properties of films and the antioxidant efficacy on cheese samples was observed, suggesting that not only the antioxidant properties but also the physicochemical properties of the films had a direct impact on cheese quality and preservation. Films prepared with both BCEs at 50:50 BCE:kappa-c ratio and those prepared with BCE-a at 25:75 BCE:kappa-c ratio, presented good antioxidant capacity and a good compromise for physicochemical properties. However, from the economical point of view, 50:50 BCE-b:kappa-c films are more suitable since the extraction protocol of BCE-b was simpler and the yield was three-fold higher.

Water-induced shape memory behavior of poly (vinyl alcohol) and p-coumaric acid-modified water-soluble chitosan blended membrane

Shape memory polymer (SMP), composites and blends need to be prepared to improve the properties or obtain new functions of SMPs. In this work, we successfully prepared p-coumaric acid-modified water-soluble chitosan (M-Cs) and poly (vinyl alcohol) blended membrane (PVA/M-Cs) by a simple solution casting method to enhance its physico-chemical properties, including water-induced shape memory behavior. M-Cs were synthesized from native chitosan (Cs) using carbodiimide chemistry. After the addition of M-Cs into the PVA polymer matrix, it exhibited better water-induced shape memory behavior and shape recovery ratio reach nearly 100 %. Moreover, the water contact angle value declined after the addition of Cs or M-Cs in to the PVA polymer matrix. Based on these findings, the respective blended membranes will be able to broaden the applications of SMPs in many sectors, especially in the biomedical field, which requires water as the main stimulus.

Improving heterogeneously catalyzed transesterification reaction for biodiesel production using ultrasound energy and petro-diesel as cosolvent

Heterogeneously catalyzed transesterification process has by far been one of the most popular methods of biodiesel production particularly for the oil feedstock containing large amount of free fatty acid. However, the major constraint of the method is the poor yield of biodiesel and a long reaction time that increased its production cost. With an objective to increase the product yield in lesser time, the current work investigated the effect of addition of ultrasound and addition of cosolvent in the heterogeneously catalyzed transesterification reaction. Three commonly used solid catalyst – calcium oxide (CaO), calcined sodium silicate (CSS) and sulfated zirconia (SZ) were chosen for study. The results suggested that there was a remarkable increase in the yield of biodiesel in comparison to the conventional mechanically stirred process. CSS showed the best catalytic activity both in first use and in repeated uses. It gave a maximum yield of 97% biodiesel in 120 minutes with 9:1 molar ratio of alcohol to oil 3 wt.% of catalyst and 10 wt.% of catalyst. For CaO and CSS a noticeable difference in biodiesel yield was observed upon addition of cosolvent. CaO gave 76% yield with cosolvent and 65% without it. SZ gave 73% biodiesel with cosolvent and 61% without. Since petrodiesel was used as the cosolvent it was not required to remove the cosolvent from biodiesel during the purification process.

Interplay between dietary phenolic compound intake and the human gut microbiome in hypertension: A cross-sectional study

In the present study, potential associations between dietary phenolic compounds (PCs), gut microbiota composition and targeted faecal metabolites were identified in a cross-sectional study including grade 1 hypertensive (HT) and normotensive (NT) subjects. We performed comprehensive quantification of PC intake, together with 16S rRNA gene sequencing of the gut microbiota, and faecal and plasma short-chain fatty acids (SCFAs) determination. The results showed multiple-way relationships between PCs from several plant-based foods and 25 bacterial taxa previously defined as discriminant biomarkers among groups. Remarkably, coffee PCs were positively associated with systolic and diastolic blood pressure, faecal SCFAs, Bacteroides plebeius and Bacteroides coprocola in HT and negatively associated with Faecalibacterium prausnitzii and Christensenellaceae R-7 in NT. Olive fruit PCs were positively associated with Ruminococcaceae UCG-010, Christensenellaceae R-7 and plasma SCFAs in NT. These interplays with discriminant bacterial taxa in HT and NT subjects highlight the potential role of specific PCs as gut microbiome modulators in either the pathogenesis or prevention of hypertension.
