A new integrated strategy for high purity pinolenic acid production from Pinus koraiensis Sieb. et Zucc seed oil and evaluation of its hypolipidemic activity in vivo

Pinolenic acid is a polyunsaturated fatty acid present only in Pinus koraiensis Sieb. et Zucc seed oil. In order to solve the structural instability problem of polyunsaturated fatty acids, pinolenic acid of P. koraiensis seed oil was effectively isolated and purified by the integrated strategy of ethyl esterification followed by urea inclusion for the first time. Under the optimal conditions after the Box-Benhnken Design experimental, ethyl pinolenate with high purity 94.95% could be obtained, and the average content of PNAEE can still reach 86.18%. Then ethyl pinolenate was characterized by Gas chromatography-mass spectrometry, Fourier transform infrared, and Nuclear magnetic resonance spectra, results showed that ethyl pinolenate was successfully prepared. In addition, the hypolipidemic activity of ethyl pinolenate had been tested in vivo and showed that ethyl pinolenate had obvious hypolipidemic activity. The new strategy for high purity ethyl pinolenate production from P. koraiensis seed oil possesses great potential in food healthy field in the future.

In-situ capture defects through molecule grafting assisted in coal-based hard carbon anode for sodium-ion batteries

Sodium-ion batteries is not essential but also potential to support energy storage system due to the low cost. It's worth noting that low price and high carbon production helps coal extraordinary promise as hard carbon precursor. However, low initial coulombic efficiency (ICE) and practical Na+ storage specific capacity barrier their application owing to lots of defects. Herein, a grafting method is proposed to decrease defects, introducing glucose with simple one step carbonization process. Utilizing the reaction between glucose and coal reduces the defects, which generates a high ICE with less irreversible sodium ion consumption. Meanwhile the expanded carbon layer spaces enable the fast sodium ions transfer, leading to an optimized sodium storage performance. The grafted glucose obviously decreases the defects during the carbonization process and contributes extra sodium storage capacity. The optimal CG0.1 exhibits higher reversible capacity of 293 mAh∙g−1 and ICE of 84 % than pristine coal pyrolytic carbon (250 mAh∙g−1 and 79 %). Besides, it also delivers outstanding capacity retention with 95.3 % and 95.8 % after 1000 cycles at 0.3 A∙g−1 (240 mAh∙g−1) and at 1 A∙g−1 (207 mAh∙g−1)

Use of vegetable oils as dielectric fluids for electrical discharge machining. A case study

Electrical discharge machining with solid electrodes represents an efficient solution to generate blind cavities with complex geometry. Vegetable oils represent an alternative to conventional dielectrics, which are considered harmful for the environment and human health. This study tested the feasibility of two widely used vegetable oils, sunflower and soybean, under intense machining of three alloys with application in aeronautic industry, aiming for high process productivity and a good surface quality. The results have revealed that vegetable oils are capable to ensure an improvement of the material removal rates that can reach up to 55.15% compared to mineral oil. Also, the vegetable dielectrics allowed an improvement of surface quality for non-ferrous alloys, up to a maximum of 19.70%, whereas for the stainless steel, the mineral oil has provided a better surface finish.

Investigating the chemical stability and thermal functionality of DMPT promoted TiO2 nanoparticles on unsaturated polyester resin

The incessant emergence of failures in mining roofs, along with escalating demands for high and sustainable roof support products such as resin anchor bolt capsules (resin), necessitates strengthening these elements. This study explores the transformative influence of Titanium oxide nanoparticles (TiO2) and its concentration on the chemical properties, stability, and thermal performance of polyester resin (UPE) nanocomposites. The investigation was carried out using Fourier-transform infrared (FTIR), Raman spectroscopy, and X-ray diffraction (XRD). Rheological behavior was assessed with a Brookfield viscometer, while thermal stability was examined via thermogravimetric analysis (TGA, DTG, and DTA). From the results obtained, the addition of nanoparticle TiO2 yielded a little significant change in the shift of the FTIR wavelength. However, substantial Raman peak disappearance from the peaks of the UPE neat compared to composites. The shift in Raman is associated with an increase in crystallinity due to TiO2 content. X-ray diffraction confirms the seamless presence of anatase TiO2 nanoparticles in the polyester resin matrix. The resin curing kinetics exhibit a 50-second reduction in the time to reach the exothermic peak when the nanomaterial content reaches 3% in TiO2. An increase in nanomaterial content leads to a shorter time to peak at a higher exothermic temperature, indicating improved resin cure rates. This study substantiates enhanced chemical and thermal stabilities with increasing nanomaterial content, affirming the positive impact of nanomaterial infusion on resin resilience and stability.

Farmland mulching and optimized irrigation increase water productivity and seed yield by regulating functional parameters of soybean (Glycine max L.) leaves

In both arid and semi-arid regions, adopting field mulching can effectively optimize soil moisture distribution, enhance crop yields, and improve water productivity. While acknowledging its advantages, field mulching seems insufficient for maintaining high crop productivity due to the increasing frequency of extreme weather. Furthermore, drought often coincides with critical crop growth stages, necessitating the implementation of agricultural irrigation to ensure normal crop growth. Accordingly, we conducted a three-year field experiment from 2021 to 2023 including three typical field mulching methods (no mulching, NM; straw mulching, SM; plastic film mulching, FM) and three supplementary irrigation strategies (irrigated at the branching stage (V4), W1; irrigated at the pod-filling stage (R2), W2; irrigated at both the V4 and R2 stage, W3). Throughout the entire growth period, we monitored soil moisture conditions for each treatment, measured leaf physiological parameters at crucial growth stages, and assessed soybean yields and water productivity (WP). Our findings indicated that, relative to SM and NM, FM maintains optimal soil moisture balance, augments chlorophyll content, and enhances photosynthesis, resulting in an average yield increase of 17.0% and 38.3% over three growing seasons. Additionally, supplementary irrigation also significantly affects the growth and seed yield of soybean. FMW2 achieved the higher seed yield (4307.5kgha-1, 3-year averaged), had insignificant difference with the highest seed yield of 4568.6kgha-1, both significantly higher than other treatments. Similarly, the leaf area index, chlorophyll content, net photosynthetic rate (Pn) and transpiration rate (Tr) also presented insignificant difference between FMW2 and FMW3, while WUEleaf (Pn/Tr) of FMW2 obviously higher than that of FMW3. As a result, FMW2 achieved the highest WP of 12.2kgha-1 mm-1 over the three growing seasons, compared to the three-year average of the other treatments, the increase ranges from 5.6% to 46.7%. In summary, the FMW2 treatment optimized water distribution to meet the water demands of soybeans during the reproductive growth stages, achieving a beneficial balance between soybean seed production and WP by regulating leaf functional parameters. Future research will explore more specific irrigation scheduling techniques (e.g., precision irrigation, deficit irrigation, and sensor-based irrigation management systems) while integrating innovative agricultural film materials (e.g., biodegradable films) to further enhance crop resilience and productivity under evolving climatic conditions.

Relações entre variáveis do maracujá amarelo e roxo

ABSTRACT Brazil is the world’s largest producer of passion fruit, with the species Passiflora edulis Sims (yellow and purple passion fruit) being the most popular commercially. Due to the great economic importance of this culture, seeking high productivity, phytotechnical quality, and maintenance of existing germplasms, among others, it is necessary to carry out studies of the most diverse types of this culture. In this crop, the use of multivariate techniques has increasingly driven studies on genetic differences between passion fruit species. Therefore, this research aimed to identify the variables that deserve greater emphasis in experiments with two commercial species of Passiflora: Passiflora edulis Sims f. edulis (purple passion fruit) and Passiflora edulis Sims (yellow passion fruit), verifying if the species differ from each other. For this purpose, principal component analysis, multivariate analysis of variance (MANOVA), and Hotelling’s T2 test were performed. The principal component analysis proved to be effective, allowing the removal of five variables for yellow passion fruit and six variables for purple passion fruit and yellow passion fruit present contrasting differences between them, being the explanatory variables for the purple passion fruit the external and internal color and for the yellow passion fruit length, diameter, and citric acid.

Nitrogen Supply from Soil Organic Matter: Predictors and Implications for Recommended Nitrogen Application Rates in Northern Highbush Blueberry

Nitrogen (N) management is a key component to maintaining high productivity of northern highbush blueberry (Vaccinium corymbosum L.) and nitrogen is often supplied by applying ammonium-based fertilizers. It can also be supplied through mineralization of soil organic matter (SOM), although the amount released by SOM is difficult to predict and not always considered in the development and implementation of N fertility programs. Laboratory and field experiments were conducted to estimate the timing and magnitude of net N mineralization from SOM throughout the growing season, identify soil properties that can be measured commercially and used to predict net N mineralization across a range of SOM, and determine whether N requirements for maximizing yield and fruit quality of blueberry vary across soils with different amounts of SOM. The laboratory experiment was conducted for 6 months using soil samples collected from 10 representative commercial blueberry fields in northwest Washington. The soils contained 2% to 42% soil organic carbon (SOC). The mean net N mineralization rates were fastest during the first 3 to 4 months of incubation, corresponding to the period during which N uptake reaches its maximum in blueberry. Results indicated that the soil total N may be a useful predictor of the N supply from SOM (6.34 ± 1.13 kg⋅ha−1 increase in net N mineralization with each 0.1% increase in total N), but there was substantial variability in the N supply that could not by explained by the total N (P < 0.001; r2 = 0.433). The field experiment was conducted from 2019 to 2021 and included four mature, regionally representative, commercial fields of ‘Duke’ blueberry. The fields contained 3% to 28% SOC and were each fertilized with low, medium (control), or high N rates, corresponding to 33 to 50, 67 to 84, or 102 to 118 kg⋅ha−1 N per year, respectively. Although soil inorganic N levels suggested that N mineralization was substantial at sites with higher SOM, sites with lower SOM did not require more fertilizer N than those with higher SOM. Under the conditions of this experiment, even the lowest N rates were sufficient to sustain production for at least 3 years at each site. The findings of this study indicate that SOM may be an important contributor to N fertility in managed blueberry systems, and that yield and fruit quality can be maintained across various N fertilizer rates, including at rates <50 kg⋅ha−1 N. However, the long-term impacts of reducing N application rates remain unclear, and future research should monitor long-term changes in plant health and soil fertility associated with reduced N applications across diverse soils and production systems.

A Mamdani fuzzy inference system with trapezoidal membership functions for investigating fishery production

Seas, marine ecosystems, and coastal regions are crucial components of our environment. Numerous scientific strategies have been adopted to boost fisheries and aquaculture productivity. This study proposes a fuzzy-logic-based model to produce fisheries in India, which ranks fourth worldwide for fisheries production. Five input variables, such as fish seed, export, post-harvesting, released fund, and temperature, are considered inputs, and the production of fisheries is taken as the output variable. A Mamdani-type fuzzy inference system with trapezoidal membership functions is prepared with 243 rules in the IF-THEN format. This mathematical model investigates the impacts of input parameters on the production of Indian fisheries. We fit the model with the real-world data and show that fish seed, export, released fund, and post-harvesting facilities positively impact fisheries production. However, a very high temperature is unsuitable for high production, even if all other parameters lie at their desired level.

A Novel GE-Mackinsey Market Approach: Investment Opportunity for the Biopolymer Packaging Materials

Sustainable development in agriculture seeks to implement a robust bioeconomy strategy by valorizing agricultural resources into value-added products. Compared to primary biomass use, using agriculture residues and wastes can achieve higher reductions in GHG emissions and lower feedstock costs. Bioeconomy has substantial potential for high-value products such as biopolymers, pharmaceuticals, and food and feed additives. Low-value applications like bioenergy, biofuels, and bulk chemicals have a weak potential for bioeconomy development. However, high value-added products, including biopolymers, require an equal focus as other products in the bioeconomy value pyramid that can lift the market to elevate sustainable bioeconomy development. A successful transition through radical innovations must be justifiable, with economic, environmental, and social benefits primarily promoted by stakeholders, businesses, or government organizations. One of the core options would be to know the market potential of the biopolymer products. Here, a methodology for decision-making to evaluate four existing biopolymer packaging materials (Cellulose, PHA, PLA, and starch) in the EU market has been developed using the GE-McKinsey Nine-Box Matrix, considering market attractiveness and product competitive advantage. Market innovations can be fostered by integrating the resource availability and technology advancement indicators to the methodology steps. The methodology considers sustainability advantages for the agriculture sector and promotes the strategic commercialization of biopolymer packaging materials. Product-specific indicators are used to evaluate the market attractiveness and product competitive advantage. The research findings show that PLA biopolymer packaging material has the highest potential for commercialization. The application of this methodology and its results provide a justifiable way of determining the investments in value-added products and allow investors to make the right decision-making choice for bioplastic packaging materials, ensuring their sustainability and profitability in the market.

Bioprocess monitoring applications of an innovative ATR-FTIR spectroscopy platform

Pharmaceutical manufacturing is reliant upon bioprocessing approaches to generate the range of therapeutic products that are available today. The high cost of production, susceptibility to process failure, and requirement to achieve consistent, high-quality product means that process monitoring is paramount during manufacturing. Process analytic technologies (PAT) are key to ensuring high quality product is produced at all stages of development. Spectroscopy-based technologies are well suited as PAT approaches as they are non-destructive and require minimum sample preparation. This study explored the use of a novel attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy platform, which utilises disposable internal reflection elements (IREs), as a method of upstream bioprocess monitoring. The platform was used to characterise organism health and to quantify cellular metabolites in growth media using quantification models to predict glucose and lactic acid levels both singularly and combined. Separation of the healthy and nutrient deficient cells within PC space was clearly apparent, indicating this technique could be used to characterise these classes. For the metabolite quantification, the binary models yielded R2 values of 0.969 for glucose, 0.976 for lactic acid. When quantifying the metabolites in tandem using a multi-output partial least squares model, the corresponding R2 value was 0.980. This initial study highlights the suitability of the platform for bioprocess monitoring and paves the way for future in-line developments.

Magnitude of preterm birth and associated factors Among mothers who gave birth in Debre Berhan comprehensive specialized hospital

BackgroundPremature deliveries are a major public health issue, with high health, economic, and productivity costs associated with lengthy hospitalizations in neonatal critical care units. The goal of this study was to determine the number of premature births in Ethiopia's Debre Berhan Comprehensive Specialized Hospital and the factors that influence them.MethodsThe Debre Berhan Comprehensive Specialized Hospital conducted an institution-based cross-sectional study between February and April 2020. A total of 325 study participants were selected using systematic random sampling. Face-to-face interviews using a pre-tested semi-structured questionnaire were used to collect data. For data entry and analysis, Epi data version 3.1 and SPSS version 20 were used. At a P-value of 0.2, bivariate logistic regression analysis was used to categorize candidate variables to the next level, and variables in multivariate logistic regression models with a p-value of 0.05 were considered statistically significant.ResultPreterm births accounted for 16.1% of all births at Debre Berhan Comprehensive Specialized Hospital. Cesarean section [AOR = 2.412; 95% CI (1.154, 5.0370)], twin pregnancy [AOR = 3.524; 95% CI (1.114, 11.150)], and maternal anemia during pregnancy [AOR = 3.124; 95% CI (1.417, 6.887)] were statistically significant associations with the outcome variable in the final logistic regression model.Conclusion and recommendationPreterm birth was found to be greater in the study area than in the Global Action Report for Sub-Saharan Africa and a few other countries. Efforts should be made to prevent maternal health issues that lead to caesarean section, and all pregnant mothers should be supplemented with iron and folic acid as soon as feasible. This study suggests that there is still a gap in the field in terms of health service intervention.

Deciphering of the morpho-physiological traits of two native grasses from Argentina with contrasting drought resistance strategies

Context Semiarid environments, such as the Patagonian shrublands, are characterised by having shrubby patches surrounded by grasses with different ecophysiological strategies to tolerate long dry periods. Aims We hypothesised that coexisting grasses of the Patagonian rangeland, already classified as drought-escaping or drought-tolerant, have different traits according to the season and the annual rainfall events. Methods Two dominant native grasses were selected: Pappostipa speciosa (evergreen) and Poa ligularis (deciduous). Samples were collected in the four seasons for the term of 1 year. Rainfall events and soil water content of each season were determined. Spring was the wettest season and autumn the driest. Physiological (relative water content, pigments, hormones), biochemical (polyphenols, antioxidant activity) and morphological traits were measured in the four seasons. Key results P. speciosa was characterised by keeping evergreen leaves with high production of polyphenols as secondary metabolites with high antioxidant capacity during the dry autumn and winter seasons. P. ligularis was characterised by high contents of gibberellin (GA1), auxin (IAA), total phenols, total flavonoids and tartaric acid esters, and high antioxidant capacity in roots during the autumn dry season. In addition, P. ligularis leaves had higher content of carotenoids and polyphenols than P. speciosa during the summer dry season. Conclusions The major adaptive strategy to tolerate dry periods is the high activity of the secondary metabolism, mainly in leaves in P. speciosa (a drought-tolerant grass) and in roots in P. ligularis (a drought-escaping grass). Implications Rainfall variations during a year can affect the phenological growth stages and the metabolism of two native grasses from Argentina characterised by different drought resistance mechanisms.

Pharmacist administered parenteral medications: A descriptive report of an inpatient training program

AbstractIntroductionParenteral medication administration is a crucial aspect of in‐hospital patient care and has been historically managed by nurses and physicians. Despite pharmacists' extensive training in the medication use process, their underutilization in medication administration stems from various factors, including the lack of formalized training, limited awareness by other healthcare professionals, and unclear legal guidance. This report discusses the implementation and outcomes of a pharmacist medication administration program at a large academic medical center.MethodsThe initiative began by revising hospital policies, enabling pharmacists to administer medications during emergencies. Documentation and communication protocols were established. Training included an online module and hands‐on sessions covering various topics with a focus on parenteral medication administration and medication safety. Following completion of the program, competency of pharmacists was assessed by pharmacists experienced in intravenous administration using simulated patient case scenarios. Following implementation, the frequency and characteristics of pharmacist administered medications were captured and described.ResultsThirty pharmacists, including 11 residents, participated. Seven pharmacists administered 349 doses of medications to 284 patients in emergency situations. Administrations by pharmacists included 227 titratable infusions, 72 intermittent or continuous infusions, 49 intravenous pushes, and 1 intranasal naloxone. Classes of medications included high risk products such as vasopressors, sedatives, antiarrhythmics, and thrombolytics. No extravasations or infiltrations were reported.ConclusionImplementation of the pharmacist medication administration program signifies significant progress in strengthening the pharmacists' role in patient care at the bedside specifically highlighting the competency of pharmacists to administer parenteral products during emergency situations. The absence of adverse events highlights the feasibility and safety of integrating pharmacists into the bedside team. As the landscape of health‐system pharmacy evolves, embracing standardized training programs like ours reemphasize pharmacists' essential contributions to the multidisciplinary healthcare teams, ultimately enhancing patient care and safety.

Uncovering the lignin-degrading potential of Serratia quinivorans AORB19: insights from genomic analyses and alkaline lignin degradation

BackgroundLignin is an intricate phenolic polymer found in plant cell walls that has tremendous potential for being converted into value-added products with the possibility of significantly increasing the economics of bio-refineries. Although lignin in nature is bio-degradable, its biocatalytic conversion is challenging due to its stable complex structure and recalcitrance. In this context, an understanding of strain's genomics, enzymes, and degradation pathways can provide a solution for breaking down lignin to unlock the full potential of lignin as a dominant valuable bioresource. A gammaproteobacterial strain AORB19 has been isolated previously from decomposed wood based on its high laccase production. This work then focused on the detailed genomic and functional characterization of this strain based on whole genome sequencing, the identification of lignin degradation products, and the strain’s laccase production capabilities on various agro-industrial residues.ResultsLignin degrading bacterial strain AORB19 was identified as Serratia quinivorans based on whole genome sequencing and core genome phylogeny. The strain comprised a total of 123 annotated CAZyme genes, including ten cellulases, four hemicellulases, five predicted carbohydrate esterase genes, and eight lignin-degrading enzyme genes. Strain AORB19 was also found to possess genes associated with metabolic pathways such as the β-ketoadipate, gentisate, anthranilate, homogentisic, and phenylacetate CoA pathways. LC–UV analysis demonstrated the presence of p-hydroxybenzaldehyde and vanillin in the culture media which constitutes potent biosignatures indicating the strain’s capability to degrade lignin. Finally, the study evaluated the laccase production of Serratia AORB19 grown with various industrial raw materials, with the highest activity detected on flax seed meal (257.71 U/L), followed by pea hull (230.11 U/L), canola meal (209.56 U/L), okara (187.67 U/L), and barley malt sprouts (169.27 U/L).ConclusionsThe whole genome analysis of Serratia quinivorans AORB19, elucidated a repertoire of genes, pathways and enzymes vital for lignin degradation that widens the understanding of ligninolytic metabolism among bacterial lignin degraders. The LC-UV analysis of the lignin degradation products coupled with the ability of S. quinivorans AORB19 to produce laccase on diverse agro-industrial residues underscores its versatility and its potential to contribute to the economic viability of bio-refineries.

Optimizing processing strategies for eco-friendly bamboo curved components: Insights from bamboo internode and node differences

Eco-friendly and high-strength bamboo curved components (BCCs) produced from sustainable bamboo are an ideal substitute for plastic curved components. However, there are challenges in the processing of bamboo into complex curved components due to the differences in bamboo internodes and nodes. Herein, we fabricated L-shaped curved bamboo strips (CBSs) and BCCs using the integrated bending forming process and investigated the performance relationships among bamboo strips, CBSs, and BCCs based on bamboo internode and node differences. Both bamboo internode strips and bamboo node strips exhibited pronounced asymmetric bending behaviors when bent parallel to the grain. The toughness of bamboo internode strips was approximately 1.5 times higher than that of bamboo node strips, resulting in a significantly increased bending pass rate when utilized as raw materials for curved components. The transverse and longitudinal interwoven vascular bundle structure and the high cellulose crystallinity of bamboo nodes were not conducive to the bending stability of the CBSs. To achieve accurate processing of bamboo curved products with high efficiency and product quality, it is recommended to apply bending load on the side with the lower vascular bundle content in bamboo strips and avoid bamboo nodes at the bending arcs of the components, which can improve the yield by about 50 %. The results are of great significance for the promotion of “Replacing Plastic with Bamboo” and the application of bamboo curved products in furniture, construction, interior decoration, and packaging.
