Esecuzione contrattuale da parte di un terzo regolata dalla lex contractus ed efficacia dell’azione di annullamento nelle procedure di insolvenza: nota alla sentenza della Corte di Giustizia dell’Unione Europea, 22 aprile 2021, C-73/20
Upon a request for a preliminary ruling on the articulation between Article 13 of the European Insolvency Regulation n° 1346/2000 and Article 12(1)(b) of Rome I Regulation, the Court of Justice of European Union has confirmed in a decision on April 22, 2021 that a payment made in perfor-mance of a contract by a third party is subjected to the law applicable to that contract and not to the law of the Member State opening the insolvency proceedings where the payment is challenged by an avoidance action. The decision raises some reflections on the correlation between the European Insolvency and Rome I Regulations as well as the effectiveness of avoidance action in insolvency proceedings
An induction theorem and nonlinear regularity models
A general nonlinear regularity model for a set-valued mapping , where and are metric spaces, is considered
using special iteration procedures, going back to Banach, Schauder, Lusternik
and Graves. Namely, we revise the induction theorem from Khanh, J. Math. Anal.
Appl., 118 (1986) and employ it to obtain basic estimates for studying
regularity/openness properties. We also show that it can serve as a
substitution of the Ekeland variational principle when establishing other
regularity criteria. Then, we apply the induction theorem and the mentioned
estimates to establish criteria for both global and local versions of
regularity/openness properties for our model and demonstrate how the
definitions and criteria translate into the conventional setting of a
set-valued mapping .Comment: 28 page
A combined analytical and experimental approach for prediction of properties of Fused Deposition Modeling (FDM) parts
Includes vita.Fused Deposition Modeling (FDM) is a technique used to build rapid prototypes out of thermoplastic materials. Printing technology continues to mature from a rapid prototyping process to a rapid manufacturing technique, therefore predicting printed part behavior has become increasingly desirable. This study aims to determine the relation between the process parameters and associated temperature history and the strength of printed parts. A combined analytical and experimental approach was used for studying and prediction properties of printed parts. The results indicate that process parameters and temperature history have a significant impact on the behavior of printed parts. Further research is needed to identify other factors that could improve the effectiveness of printed part behavior.Includes bibliographical references (pages 59-65
Effect of plant density and foliar fertilizer spray on growth and yield of netted melon (Cucumis melo L.) ‘Inthanon RZ’
The cultivation of netted melon is becoming popular in vegetable farms in Vietnam. The netted melon cultivar ‘Inthanon RZ’ was evaluated for its growth ability, yield, fruit quality, and economic efficiency when treated with densities of 38,000 and 33,000 plants/ha and four foliar fertilizer sprays: Biotic foliar AMINO ACID 1000, NPK NUTRI-GOLD 29-10-10 + 3 MgO + TE, NPK HAI-CHYODA 14-17-12 + 12 S, and NPK DAU TRAU 30-10-5 + TE. The experiment was conducted in a plastic house at the Biotechnology Institute of Hue University from January to April 2019. The experiment area was 72 m2. The results indicate that plants have a similar growth time under the cultivation conditions. The plants grown with the density of 38,000 plants/ha exhibit a higher leaf area index. The actual yield ranges from 34.00 tons/ha (AMINO ACID 1000; 33,000 plants/ha) to 46.22 tons/ha (NPK HAI-CHYODA 14-17-12 + 12 S; 38,000 plants/ha). Applying NPK HAI-CHYODA 14-17-12 + 12S or NPK DAU TRAU results in the Brix grade higher than 12.0 for both plant densities. Powdery mildew is the most frequently observed in the treatments with NPK DAU TRAU. The yield and profit obtained from trading the melon are highest for the density of 38,000 plants/ha with fertilizer NPK HAI-CHYODA 14-17-12 + 12S
Influence of nitrogen level and plant density on growth parameters and economic efficiency of sunflower cultured in Thua Thien Hue province
Sunflower (Helianthus annuus) cultivation is gaining popularity among Vietnamese farmers. Two separate experiments were conducted from January to April 2018 in a randomized complete block design with three replicates. Four levels of each factor were included in the experiments: 0, 20, 40, and 60 kg/ha for nitrogen and 11, 13, 16, and 20 plants/m2 for the density. The nitrogen fertilizer (up to 60 kg/ha) substantially affects the leaf area, diameters of stem plant, receptacle and flower head, and cut flower vase life. Low plant density works well on plant height, leaf number, width and length at the flowering stage, with the largest head diameter (17.2 cm) at the 13 plants/m2 density. Based on the results of both growth ability and economic efficiency, we suggested applying N at 60 kg/ha and planting at 16 plants/m2 density for growing F1 cut sunflowers in Thua Thien Hue province
A Model-based Dynamic Toll Pricing Strategy for Controlling Highway Traffic
A model-based approach to dynamic toll pricing has
been developed to provide a systematic method for determining
optimal freeway pricing schemes. A novel approach is suggested
for alleviating congestion, which utilizes identified models of
driver behavior and traffic flow, as well as optimization of
the target density to maximize throughput. Real-time traffic
information from on-road sensors is integrated with historical
information to provide feedback and preview for the dynamic
toll price controller. The algorithm developed here provides an
opportunity to improve on existing toll policy by guaranteeing
minimum speeds for toll lane drivers, maintaining consistent
traffic flow for the other drivers, and optimizing the overall traffic
throughputthe Ford-MIT Allianc
Revisiting Lifelong Learning and Its Practices in Vietnam
Education is an indispensable sector for a country's sustainable development. To maintain its continuity, government-based policies and related stakeholders in learning need to be considered to promote lifelong learning. This narrative literature review addresses international concepts of lifelong learning in Europe and how it has been implemented in Vietnam. The findings indicated that Vietnam faced more challenges than other developed countries, and some factors impacted LLL in Vietnam, such as legal frameworks, facilities, foreign language literacy, etc. The review also provided discussions for lifelong learning in Vietnam
