Buah okra kaya akan manfaat yang berguna memenuhi nutrisi yang dibutuhkan oleh tubuh. Melatonin merupakan biomolekul pleiotropik alami yang ditemukan secara luas pada tumbuhan maupun hewan untuk meningkatkan hasil, pembungaan, pembentukan dan perkembangan buah, partenokarpi, dan ripening. Penelitian bertujuan mengetahui respon melatonin eksogen terhadap performa dan perkembangan organ generatif tanaman okra. Penelitian dilakukan pada Desember 2021-Februari 2022 di lahan okra PT. Gading Mas Indonesia Teguh, Ajung, Jember, Indonesia. Pemberian melatonin dilakukan secara eksogen dengan menyemprotkan ke semua bagian tanaman okra yang sudah masuk fase generatif. Percobaan dilakukan dengan satu faktor konsentrasi melatonin dengan empat taraf yaitu 0 µM, 200 µM, 350 µM, dan 500 µM. Kombinasi perlakuan dilakukan pengulangan sebanyak lima kali sehingga didapatkan 20 satuan percobaan. Hasil penelitian menunjukkan melatonin berpengaruh terhadap performa dan kualitas tanaman okra. Konsentrasi 350 µM menghasilkan rata-rata jumlah daun tertinggi 14.8 daun. Konsentrasi 500 µM menghasilkan waktu gugur kelopak paling lama dengan rata-rata 4.8 hari dan persentase keberhasilan pembentukan buah sebesar 100 %. Variabel jumlah biji paling tinggi pada perlakuan kontrol dengan rata-rata 57.2 biji dan pematangan buah atau ripening paling lama pada konsentrasi 500 µM dengan rata-rata 33.6 hari.

Genetic analysis and inheritance patterns studies on agronomic and yield characters were required to develop a plant breeding program. This study aimed to obtain information on agronomic and yield performance, gene action, genetic diversity, and heritability in the F2 population derived from crosses of local and high-yielding varieties. The study was conducted in August-November 2021 in Dramaga, Bogor. The F2 sorghum population, female and male parents, and also ten check genotypes were used in this study. The results showed qualitative characters in the F2 population indicated the female parent trait was strongly inherited in F2. A few genes controlled the quantitative characters via additive gene action for days to flowering, plant height, stem diameter, leaf length, panicle length and diameter, also wet and dry panicle weight. Meanwhile, the leaf number and width, also grain weight per panicle were controlled by complementary epistasis. The wet and dry panicle weight had a significant positive correlation (0.9 and 0.95) with grain weight per panicle although there had low h2bs (0%). Panicle length and diameter could be used as indirect selection characters because of their significant positive correlation (0.67 and 0.7) to grain yield and high h2bs (90 and 80%).

Authors: Miller Nancy , Engel-Enright Carol , Brown David
Published: January 2023

Studies have highlighted the benefits of external knowledge building as a means of heightening a firm’s innovation activities. Simultaneously supply chain scholars have highlighted the lack of focus on social facets at the micro behavioral level, as well as the limited endeavors to build upon existing theories for new perspectives. Taking an exploratory approach to addressing literature gaps, the objectives of this research involve integrating constructs from social capital theory and the knowledge-based view of the firm to examine associations and interactions among network ties, social interactions, knowledge absorptive capacity, and knowledge acquisition in the development of new product innovations by US apparel and sewn products manufacturers (N=125). Quantitative data were collected via an online survey of both a national and state sample of small sized manufacturers. Findings regarding new product development indicated: positive associations for network ties, social interactions, knowledge absorptive capacity, and knowledge acquisition; network ties and knowledge acquisition; mediated relationships with social interaction and absorptive capacity; and moderated social interaction relationships with absorptive capacity and network ties­. These empirical insights highlight the importance of building external relationships for generating knowledge in amplifying innovation. Theoretical contributions, managerial implications, limitations and suggestions for future research are presented.

Authors: Kemppainen Laura , Pikkarainen Minna , Koivumäki Timo , Xu Yueqiang
Published: January 2023

Personal data has become an important resource in today’s market and in platform business models. In fact, the essence of many platform business models is to create value for an individual by offering a free service and to capture value by collecting and selling collected data. In this study, we analyse the drivers for platform business model innovation in the context of personal data used in the healthcare sector. Platform business models are shaped and designed with respect to the internal and external drivers in the market. However, few studies have increased our understanding of the drivers for platform business model innovation. For that, we conducted an exploratory study for five personal data platform providers that enable individuals to control the use of their personal data in digital services by interviewing the personal data platform providers and using company presentation material. The findings show that by adopting a human-centred approach to personal data, giving control over data to the individual, personal data platform providers change how value is created and captured. This research has managerial implications and contributes to the business model innovation literature by extending the current knowledge about drivers for personal data-based platform business model innovation in the healthcare sector.

MAMÍFEROS REGISTRADOS CON CÁMARAS TRAMPA EN LA ZONA DE USO TURÍSTICO DE LA RESERVA NACIONAL ALLPAHUAYO-MISHANA, LORETO, PERÚ
Authors: COSSIOS E. Daniel , DIAZ Eddy , PIZANGO Frank
Published: January 2023

La Reserva Nacional Allpahuayo Mishana, situada en la Amazonía peruana, mantiene una gran biodiversidad pero, a diferencia de sus plantas y de la mayoría de grupos de vertebrados, su comunidad de mamíferos mayores y medianos de costumbres terrestres no ha sido sujeto de evaluaciones recientes con métodos de registro directo, estando la mayor parte de esas especies reportadas únicamente a partir de huellas, entrevistas, o pieles y cráneos mantenidos por cazadores locales. Con el fin de contar con una lista actual de mamíferos terrestres de la zona de uso turístico de la reserva, realizamos una evaluación con cámaras trampa entre mayo y octubre del 2021. Adicionalmente, evaluamos la actividad horaria para las ocho especies que fueron registradas más de 10 veces. Se consiguieron 656 registros independientes de mamíferos que correspondieron a 19 especies identificadas al menos a nivel de género, incluyendo 17 de costumbres terrestres y dos principalmente arborícolas. Varias especies reportadas por otros autores en distintos lugares de la RNAM no fueron captadas por nuestras cámaras, pero conseguimos registrar una especie amenazada que se creía extinta en el área: el hormiguero gigante Myrmecophaga tridactyla. La actividad horaria de las especies estudiadas no mostró alteraciones con respecto a otras publicaciones. Nuestros resultados sugieren que las actividades antrópicas no alteran el comportamiento horario de los mamíferos más comunes en el área, pero si pueden tener un impacto negativo sobre la diversidad total y sobre la abundancia de ciertas especies, en especial mamíferos de gran porte y carnívoros.

Reachable Set of Low-Delta-v Trajectories Following a Gravity-Assist Flyby
Authors: Wu Chun-Yi , Russell Ryan P.
Published: January 2023

Flyby tours are challenging to design due to the extraordinarily large search space. A single algorithm is proposed to answer the question of what low-cost, post-flyby options exist for a spacecraft arriving at a flyby body. The algorithm a) considers the full domain of reachable bodies and transfer types including even- and odd-[Formula: see text] resonant ballistic, nonresonant ballistic, and [Formula: see text]-infinity leveraging; b) identifies families of solutions instead of just single points; and c) structures the search to only seek solutions within a [Formula: see text] threshold. This algorithm extends and integrates these state-of-the-art characteristics, and is designed to rapidly inform an outer-loop pathfinding scheme for flyby tour design. Detailed examples of resulting solutions and families are provided for multiple variations of three different use case scenarios, including tours in the Jupiter, Saturn, and sun systems. As a representative example in the Jupiter system starting at Callisto, the algorithm takes on the order of 0.1 s to find over 500 solutions with [Formula: see text] costs below [Formula: see text] organized into nearly 70 families, all either returning to Callisto or proceeding to Ganymede.
NM-MF: Non-Myopic Multifidelity Framework for Constrained Multi-Regime Aerodynamic Optimization
Authors: Di Fiore Francesco , Mainini Laura
Published: January 2023

The exploration and trade-off analysis of different aerodynamic design configurations requires solving optimization problems. The major bottleneck to assess the optimal design is the large number of time-consuming evaluations of high-fidelity computational fluid dynamics (CFD) models, necessary to capture the non-linear phenomena and discontinuities that occur at higher Mach number regimes. To address this limitation, we introduce an original non-myopic multifidelity Bayesian framework aimed at including expensive high-fidelity CFD simulations for the optimization of the aerodynamic design. Our scheme proposes a novel two-step lookahead policy to maximize the improvement of the solution quality considering the rewards of future steps, and combines it with utility functions informed by the fluid dynamic regime and the information extracted from data, to wisely select the aerodynamic model to interrogate. We validate the proposed framework for the case of a constrained drag coefficient optimization problem of a NACA 0012 airfoil, and compare the results to other popular multifidelity and single-fidelity optimization frameworks. The results suggest that our strategy outperforms the other approaches, allowing to significantly reduce the drag coefficient through a principled selection of limited evaluations of the high-fidelity CFD model.
Hypersonic Shock Wave/Turbulent Boundary Layer Interaction over a Compression Ramp
Authors: Zuo Feng-Yuan
Published: January 2023

A parametric study of ramp-induced planar shock-wave/turbulent-boundary-layer interactions (SBLIs) is carried out at hypersonic conditions (Mach number 6.0) by means of numerical simulation of the Reynolds-averaged Navier–Stokes (RANS) equations, with the eventual goal of establishing wall temperature and Reynolds number effects. Comparison with available experimental data shows that RANS is capable of predicting the main features of hypersonic oblique SBLI, namely, typical size and distribution of the wall-surface pressure, and heat transfer. A large number of flow cases, at low ([Formula: see text]) and high Reynolds number ([Formula: see text]), were computed to examine the scaling of the heat transfer over a wide range of wall temperatures. As expected, the interaction zone of hypersonic ramp-induced SBLI is reduced as the wall is cooled. A simple power law for heat transfer originally introduced by Back and Cuffel (AIAA Journal, Vol. 8, No. 10, 1970, pp. 1871–1873) is here considered to account for hypersonic ramp-induced SBLI, which is found to successfully collapse the data to the distributions obtained for supersonic, cold/hot interactions.
Numerical Modeling of Electric Discharges Generated in Supersonic Flows

A numerical solver is developed for the modeling of electric discharges in high-speed flows. For the formulation of the physicochemical model, common electric discharge modeling approaches are combined with detailed models for nonequilibrium aerothermodynamics and finite-rate chemical kinetics. The physicochemical model is based on the single-fluid assumption and takes into account the thermal and chemical nonequilibria in the gas mixture. For the numerical implementation, the finite-volume-based open-source CFD software package OpenFOAM is used. The verification of the calculation models for thermodynamic and transport properties as well as finite-rate chemical kinetics is carried out by means of one-dimensional simulations. The first validation of the solver is carried out by means of a three-dimensional simulation of an electric discharge with a constant input power of 10 kW generated on the surface of a wedge in a supersonic nitrogen flow. The numerically obtained results are compared with corresponding experimental measurements and theoretical calculations and show a fair agreement. The numerically calculated maximum temperature values, for example, are 20–40% above the measured values. However, it should be noted that the experimentally obtained values represent a spatial integration over the entire measurement volume and therefore do not indicate maximum temperature values.
