A clinical outcomes data archive for a comprehensive fetal diagnosis and treatment center.

Data on near and long-term outcomes are critical for the care of all maternal-fetal patients presenting to a fetal center. This is important since physiologic and neurodevelopmental attributes do not manifest until childhood when multi-level factors influence health outcomes. Electronic health records (EHR) documentation structures are not designed for acquisition of key attributes, and changes over time and between-clinician differences can affect resultant output. Therefore, EHR derived datasets have limited ability to accurately characterize the clinical presentation and care trajectory of patients with congenital anomalies. Moreover, the fetus lacks a digital identity and requires relinking attributes documented in the maternal chart to those in the pediatric EHR. This conundrum amplifies in the setting of multiple gestation, returning maternal patients, and pregnancies with fetal demise. Current data systems result in incomplete abstraction of variables that may confound, mediate, or moderate critical associations. Our objective was to develop and implement a prospective data capture platform to transform EHR data into an analytic-grade database for multi-purpose use. A unified platform for longitudinal follow-up of maternal-child dyads named the Clinical Outcomes Data Archive (CODA) was constructed. CODA was designed using a data dictionary based on multidisciplinary input, a relational identity for each patient, fetus, and pregnancy, and a process by which EHR-sourced and chart-abstracted data are validated. Descriptive analyses were performed for data acquired between July 2022 - July 2023, and a comparison of studies before and after implementation of CODA is presented. 5,394,106 data points were validated for 7,662 patients across 12 conditions. 2% of data points were found to be unreliable or undocumented. 91% of data points were sourced from the EHR. 85% of condition-specific variables required manual chart abstraction. The study conducted with CODA contributed to 18 studies. CODA successfully merges EHR-sourced and manually abstracted documentation for longitudinal study of the maternal-child dyad.

New electric starter system based on on-board power network with hydrogen energy storage

Current trends in industries related to autonomous, mobile objects, such as aircraft manufacturing, are aimed at increasing the share of electrification or completely replacing all units in favor of electric ones. Replacing components and assemblies with fully electric ones corresponds to the concept of a fully electric aircraft, which is based on new power sources and sources of electric propulsion, such as lithium-ion batteries, hydrogen batteries, and sources based on renewable energy. At the same time, the requirements for energy efficiency and weight and size parameters of components and assemblies are increasing. These needs can be met through the multi-purpose use of equipment, as well as through new systems that combine a number of functions.The article discusses the use of an aircraft three-stage synchronous generator as a starting device for a gas turbine engine. The problems associated with the use of a three-stage generator are analyzed and a method for solving them is proposed. The article presents a method for creating a starting torque using the reactive component of the electromagnetic torque for a synchronous salient pole generator. The analysis was carried out from the point of view of the formation of electromagnetic torque in an aircraft generator using a voltage inverter. A generalized expression for the torque is obtained, regulated and controlled by the electrical parameters of the frequency converter.

Protection of Oats against Puccinia and Drechslera Fungi in Various Meteorological Conditions

Due to their multi-purpose use and, in many cases, lower requirements and financial outlays for cultivation, oats are an interesting crop. However, fungal diseases may contribute to significant declines in grain yields and quality. The aspects that may potentially influence this matter of fact include weather conditions. The aim of the study was to determine the severity of diseases caused by fungi in oat cultivation during the vegetation season. The next goal was to assess the efficacy of the selected active ingredients (a.i.) of fungicides from the chemical groups of triazoles and strobilurins in selected diseases’ control under various meteorological conditions. All of the fungicides were applied in the form of a spray treatment to reduce the severity of the diseases in the cultivation of different oat varieties. Husked and naked oat varieties were used. The health status of the oat plants was determined on the basis of a macroscopic evaluation of plants performed in accordance with the proper methodology. Field experiments were carried out under different weather conditions, which varied over the years during which the trials were conducted. Statistically significant differences were found in the reduction in infection for F and F1 leaves with D. avenae and P. coronata in comparison to the control treatment, regardless of the a.i. used. The use of a.i. tebuconazole (250 g/L), a.i. epoxiconazole (125 g/L), a.i. azoxystrobin (250 g/L) and a.i. picoxystrobin (250 g/L) enabled a reduction in the severity of oat helmintosporiosis in all years of the study for all the varieties analyzed. The efficacy was 72.4%, 74.2%, 71.5%, and 73.1%, respectively. Higher efficacy in reducing P. coronata was found in comparison with D. avenae. The obtained research results confirm the satisfactory efficacy of the above-mentioned active substances in reducing the fungi D. avenae and P. coronata.

Ethnobotanical study of medicinal plants used to manage human ailments in Lay Gaint District, South Gondar Zone, Amhara Region, Northwestern Ethiopia

The aim of this work is to document and record the use of medicinal plants to treat various ailments in the study area. A total of 84 informants, consisting of 54 men and 30 women, between 35 and 80 years of age were chosen. Additionally, 20 key informants were deliberately selected for their expertise. Data were collected through face-to-face interviews, group discussions, and guided field walks using semi-structured interview questions. Ethnobotanical data were analyzed using quantitative analytical tools such as preference ranking, direct matrix ranking, fidelity level and informant consensus factor. Forty-six medicinal plants belonging to 41 genera and 33 families were collected and identified. Brassicaceae, Ranunculaceae, and Polygonaceae had the highest abundance of medicinal plants used to treat various diseases in the study area. Most of the medicinal plants were herbs (43 %), followed by shrubs (35 %). The study revealed that leaves (45.7 %) were the most frequently used plant parts in the preparation of remedies. The most common mode of administration was oral ingestion (61 %), followed by dermal application (30 %). Zingiber officinale Roscoe and Allium sativum L.had the highest preference rank, whereas Croton macrostachyus Hochst. ex Delile was identified as the most popular medicinal plant due to its multipurpose use. while the value of fidelity level (FL) for medicinal plants in the study ranged from 34 % to 94 %. The study also identified several threats to medicinal plants in the study area, including charcoal production, overgrazing, and agricultural expansion. To prevent the eradication of these medicinal plants, the involvement of local communities in the management and conservation of plant resources is crucial.

The multipurpose utilization of inorganic materials in adsorption treatment of wastewater and core-modification of color index pigment red 57:1

Purpose This study aims to realize the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified Color Index Pigment Red 57:1 (C.I. Pigment Red 57:1, PR 57:1). Design/methodology/approach In this paper, the inorganic materials (sepiolite and SiO2·nH2O) were used in both PR 57:1 production wastewater treatment and its core-modification. The inorganic material firstly adsorbed 3-hydroxy-2-naphthoic acid (bon acid) in the pigment wastewater to reduce chemical oxygen demand. Then, the inorganic material adsorbed with bon acid was reused to prepare core-modified PR 57:1. Findings In the pigment wastewater adsorption experiment, it was found that under pH = 3, the adsorption percentage of bon acid by inorganic material can reached up to 46.00%. The pigment characterization results showed that the core-modified PR 57:1 had a core-shell structure. Under UV light irradiation for 1 h, the core-modified PR 57:1 prepared with sepiolite and SiO2·nH2O showed total color difference ΔE value of 1.43 and 2.05, respectively, which was lower than that of unmodified PR 57:1 (ΔE = 2.89). In addition, the transmittance of pigment water suspension test results showed that the core-modified PR 57:1 showed better water dispersibility. Originality/value This paper attempts to develop a synergistic strategy based on the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified PR 57:1.

Liposomes in Medicine: An In-depth Analysis of Preparation Methods and Applications

Liposomes are the targeted drug administration system that offers the potential to improve the medicinal value of drugs by boosting the concentration of medication the duration of time in intended cells, thereby reducing side effects. Liposomes, which are sphere-shaped vesicles built from phospholipids and cholesterol, are being investigated extensively as a means of increasing the bioavailability and delivery of therapeutic medications. Liposomes have both hydrophilic head and hydrophobic tail and exhibit eminent properties, including reduced toxicity, better biocompatibility, easily biodegradable, easy to function and enhanced sustained release of drugs with increased therapeutic efficacy. Liposomes are said to be an ideal drug-carrier system as they enhance the delivery of anticancer drugs at the tumor site. Since liposomes are amphiphilic carriers that may be modified to have various functional characteristics, they are seen as a potential technology for a range of pharmacological and industrial uses. As a potential way to carry drug delivery across cell membranes, liposomes help medications to target specific disease sites. Liposomes are employed to deliver genetic material, such as DNA fragments, to specified cells so they may synthesize certain proteins. Thus, liposomes are investigated as adaptable nano-vesicular vehicles with potential medical applications for medicinal and diagnostic purposes. The future of liposomal formulations is projected to be a multipurpose use of imaging capabilities and medicinal components in a single liposome for diagnostic and actual-time therapy. The most promising approach for topical administration is liposomal drug delivery since it is compatible with living systems and can accommodate simultaneously hydrophobic and hydrophilic medicated substances because of the amphipathic feature of phospholipids.

Demystifying Heavy Metals and Physicochemical Characteristics of Groundwater in a Volcano-Tectonic Region of Middle Awash, Ethiopia, for Multipurpose Use

THE POND NETWORK IN THE GNIZNA RIVER BASIN: SPATIAL LIMITATION, FUNCTIONAL FEATURES, GEO-ECOLOGICAL PROBLEMS

The pond network in the basin of the Hnizna River - the left tributary of the Seret River - was considered. The multifunctional features and spatial contiguity of the ponds to the main river and its tributary of the first order have been clarified. It was established that the most regulated was the Terebna River with its tributaries Dzyurava and Kachava, within the basins of which 35% of the pond network is concentrated. 29% of the number of ponds is allocated to the basin of the right tributary of the Hnizdechna River, and 15% of the number of ponds within the main river Hnizna. The coefficient of regulation of river flow by artificial reservoirs was calculated, which demonstrates a high degree of flow regulation, the result of which is an increase in the area of the water mirror, which means an increase in evaporation from the water surface. Among the positive aspects of flow regulation, we note the absence of sudden water rises in the basin as a result of spring floods and summer floods. Thus, the hydrological regime of the main river and its tributary of the first order has been stabilized. The volume of water in the artificial reservoirs of the basin is 6.7% of the Hnizna river flow. Such volumes of regulated runoff enable its multi-purpose use for agricultural, fish farming, fire prevention, anti-erosion, recreational, sanitary and industrial purposes. A typology of ponds was carried out, which demonstrated the vast majority of artificial multi-functional reservoirs. It is worth noting fishery-recreational-farming and recreational-farming-fishing farms. In addition to these three main functions, most ponds perform the functions of fire protection reservoirs, microclimate regulators, and aesthetic ones. The conducted expedition surveys of the Hnizna River basin in 2023, in comparison with the corresponding surveys of 2007 (stock materials of the Department of Geoecology), showed a more significant orderliness of peripheral landscapes, the presence of access roads with a hard surface, which improves the accessibility of recreationists and fishermen to ponds. It is worth noting the creation in the river basin of two entertainment and recreation complexes on the pond in the village. Okhrimovtsi and "Lemkivsky stav" in the village. Old Zbarazh. In these ponds, the main attention is paid to the creation of entertainment and hotel complexes, gazebos-islands, watercraft with various recreational infrastructure. The services of these complexes include: cozy houses for families, gazebos for group recreation, baths, multi-saunas, salt rooms, a font, a tropical shower, and forms of active recreation - wakeboarding, rowing, etc. Here they offer the holding of solemn events such as birthdays, corporate vacations, weddings. Despite the positive changes in peripheral landscapes and the presence of recreational facilities, the quality of water in the main river is quite low, as evidenced by the following diagram, which shows the dynamics of the discharge of polluted or insufficiently purified return water into the Hnizna River basin over the past 7 years. Together with the polluted runoff, 63.5 tons of pollutants entered the river. Among the proposed optimization measures, it is worth noting: - improvement of the sewage treatment plant system in the city of Zbarazh, village Velyki Birky and the town of Terebovli; - to introduce an effective system of water drainage of municipal sewage in rural settlements under the responsibility of the governing bodies of territorial communities; join the system of on-site regular water monitoring of the Dniester Basin Management; strengthen the responsibility of the public in the person of the basin council of the small river Hnizna. Keywords: the basin of the Hnizna River, pond network, functional and spatial features, geoecological problems.

A review on the green chemistry perspective of multipurpose use of cow urine

Abstract The use of cow urine (CU) in treating a variety of illness can be traced back to ancient ages. It has been referred as an important and integral component of Cowpathy – an age-old practice in Indian sub-continent since the Vedic period (1500 BC – 600 BC). The CU contains several important compounds that are essential in maintaining a balance between the well-being of human and the nature. It is composed of about 95 % water and other useful ingredients such as urea, hormones, lyase enzyme, and salts containing Fe, Ca, P, Mn, S, N, and K. In addition, it also contains lactose, cytokine, and amino acid which are the fundamental building blocks of protein. Researchers have developed various processes for the green synthesis of CU concentrate and evaluated its usefulness in treating various diseases owing to its antibacterial and antifungal properties. Further, CU has also shown promising immunity boosting and anti-oxidant characteristics. Even though human civilization has benefited from the use of CU in treating various types illness but the modern scientific understanding of the cause-effect relationships was partly developed in the last few decades. There exists a huge knowledge gap and a comprehensive study on exploring the science and application of CU hasn’t been reported. This paper reviews the historical perspective, compositional analysis, processing, applications, knowledge gap, and future research required in the field of therapeutic usage of CU.

How to use polarity thinkingTM to manage tensions between accountability and learner agency when using a multipurpose portfolio?

ABSTRACT Portfolios are often implemented to target multiple purposes, e.g. assessment, accountability and/or self-regulated learning. However, in educational practice, it appears to be difficult to combine different purposes in one portfolio, as interdependencies between the purposes can cause tensions. This paper explored directions to manage tensions that are inextricably linked to multipurpose portfolio use. We used a systems thinking methodology, that was based on the polarity thinkingTM framework. This framework provides a step-by-step approach to chart a polarity map® that can help to balance the tensions present in specific settings. We followed the steps of the framework to chart a polarity map for multipurpose portfolio use. Based on literature and our prior research, we selected one overarching polarity: accountability and learner agency. This polarity seems responsible for multiple tensions related to multipurpose portfolio use. We formulated values (potential benefits) and fears (tensions that can arise) of the two poles of this polarity. Then, we organised a session with stakeholders who work with the portfolio of the Dutch General Practice speciality programme. Together we formulated action steps and early warnings that can help to balance accountability and learner agency during multipurpose portfolio use. In addition to previous recommendations concerning portfolio use, we advocate that it is important to create a shared frame of reference between all involved with the multipurpose portfolio. During this process, the acknowledgement and discussion of tensions related to multipurpose portfolio use are vital.

Characterization and drug solubilization of arginine-based ionic liquids – Impact of counterions and stoichiometry

Ionic liquids (ILs) exhibit very diverse physicochemical properties, such as non-volatility, stability, and miscibility, which render them excellent candidate excipients for multi-purpose use. Six novel arginine (Arg)-based ILs were obtained using a one-step ultrasound method. Salt formation was confirmed by Fourier-transform infrared (FTIR), Raman, and nuclear magnetic resonance (NMR) spectroscopies. Moreover, the effects of anions and molar ratio on the molecular states and thermal properties of Arg-ILs were investigated. In addition, the solubilization of drugs with different pKa and LogP values was attempted using Arg-ILs consisting of asparagine, proline, octanoic acid, and malic acid, respectively, and a comparative study was performed. Furthermore, the interaction mode between the drugs and ILs was determined by FTIR and Raman spectroscopy. Presumably, partial interaction between the component of ILs and drugs such as ofloxacin and valsartan occurred, whereas flurbiprofen and isosorbide mononitrate were dispersed in the viscous IL. The development of strategies for the application of ILs as solubilizers or carriers of active pharmaceutical ingredients is an extremely promising and wide avenue of research.

Renewable fuel production and the impact of hydrogen infrastructure — A case study of the Nordics

Hard-to-electrify sectors will require renewable fuels to facilitate the green transition in the future. Therefore, it is crucial to identify promising production locations while taking into account the local biomass resources, variable renewable energy sources, and the synergies between sectors. In this study, investments and dispatch operations are optimised of a large catalogue of renewable fuel production technologies in the open-source software SpineOpt, and this is soft-linked to the comprehensive energy system model Balmorel. We analyse future production pathways by comparing various levels of hydrogen infrastructure, including large-scale hydrogen storage, and assess system impacts. The results indicate that methanol may provide synergies in its multipurpose use as an early (2030–2040) shipping fuel and later as an aviation fuel through further refining if ammonia becomes more competitive (2050). We furthermore show that a hydrogen infrastructure increases the competitiveness of non-flexible, hydrogen-based fuel production technologies. Offshore electrolysis hubs decrease energy system impacts in scenarios with 105 TWh of Nordic hydrogen export. However, hydrogen export scenarios are much costlier compared to scenarios with no export unless a high hydrogen price is received. Finally, we find that emission taxes in the range of 250–265 €/tCO2 will be necessary for renewable fuels to become competitive.

Shading solutions for sustainable water management: impact of colors and intensities on evaporation and water quality

This study investigated the effectiveness of suspended shade covers in reducing evaporation rates and improving evaporation suppression efficiency. The experiment tested different shading colors (black, white, and green) and intensities (50, 70, and 90%) while considering ecological and economical aspects. Evaporation was determined using class-A evaporation pans, and various microclimatic variables were measured below the shade covers. Additionally, water quality parameters such as EC, phosphate, nitrate, and chloride concentrations were monitored. The results showed that black covers had the highest evaporation suppression efficiency with values of 56.8, 53.6, and 51.7% observed under 90% shading intensity for the black, green, and white covers, respectively. Despite variations in water quality parameters which all met Jordanian and FAO standards for irrigation water, the economic feasibility of installing these covers was found to be viable due to the resulting benefits in water conservation and crop production. However, selecting the best shading cover should consider the multipurpose use of agricultural reservoirs, including aquaculture, and further studies are recommended to investigate other overlapping aspects on a reservoir scale.

Hemp cultivation opportunities for marginal lands development.

Agricultural diversification and high-quality products deriving from sustainable crops such as hemp can represent a solution to revitalize marginal areas and reverse land abandonment. This study aimed at comparing four different hemp cultivars (Carmagnola Selezionata, "CS"; Futura 75, "FUT"; Felina 32, "FEL"; Secuieni Jubileu, "JUB") to provide information to select the best suited cultivar for cultivation in mountain marginal areas and for specific end-use applications. Hemp cultivars were cultivated in a single experimental field to compare their ecological and agronomic behavior (duration of life cycle phases, plant size and biomass allocation, and plant resource-use strategies). Through metabolomic analysis of both vegetative and reproductive parts of the plants we tested the presence of substances of nutraceutical interest and traced seed nutritional profile. The four cultivars had different ecological and agronomic behavior, and nutritional profile. We found several compounds with potential pharmaceutical and nutraceutical values in all parts of the plant (leaves, inflorescences, and stems). JUB resulted the most suitable for seed production while CS showed the highest content of bioactive compounds in flowers and leaves. FUT, showed the best suitability for multi-purpose cultivation, while FEL seemed to be not appropriate for the cultivation in mountain area. The multi-disciplinary approach we adopted was effective in distinguish across hemp cultivars and provided information to farmers for the selection of the best hemp cultivar to select. Hemp had a high potential for cultivation in marginal lands, demonstrating to be an economic resource due to its multi-purpose use and to the possibility to generate high-added values products. Our results could serve as a stimulus for the reintroduction of this culture in the study area and in other similar environments.

A distributed energy resources control method to improve the loading profile of radial distribution feeders using solid-state transformer

The multi-purpose use of distributed energy resources (DER) can bring a lot of income to its owners. For example, the load imbalance of the radial feeders in the distribution network is an old problem that occurs due to the simple structure of the radial topology and the unidirectional power flow in traditional networks. With emerging DERs and the development of power electronic technology, previous concepts are changing continuously. This paper aims to balance the load between two feeders whilst, it yields better voltage profiles and more appropriate utilization of distribution feeders. This paper proposes a new control method for DERs (including PV panels plus battery storage) that makes the radial system pretends a ring topology properties. It is done with the help of a solid-state transformer (SST). The relationships of the DER current controller are formulated based on current passes through the ring connection. Case studies are carried out on improved IEEE 33-node and 13-node systems with DERs and SSTs. The results show that the suggested control method can simulate the real ring topology and operating objective namely, load balancing is reached.
