Published: March 2024

Sea level anomaly (SLA) data spanning from 1993 – 2022 were used to analyze the characteristic of eddy current in Northwest Indonesian. An improved winding angle method was used and was able to detect 1663 anticyclonic eddies (AEs) and 1748 cyclonic eddies (CEs). The average eddy lifespan is approximately four weeks. The eddy in the West Indonesian Ocean has a radius ranging from 40 – 100 km and a high number of mesoscale eddy (radius more than 100 km) detected in the northern area of West Indonesian Ocean (4° N - 10° N). The eddy kinetic energy (EKE) increased proportionally with their radius, whereas the eddy vorticity decreased proportionally with their increasing radius. The seasonal cycles of eddy circulation in the west Indonesian Ocean were differ for both AEs and CEs, where AEs were dominated during east monsoon season (JJA) and CEs came with longer periods from November to March, yet for both AEs and CEs they have similar radius per month. During weak periods of both eddies, their meridional distributions differ; CEs tend to be formed in relatively lower latitude, while AEs were concentrated in relatively higher latitude. Data anomali permukaan laut/sea level anomaly (SLA) dalam kurun waktu 1993 – 2022 digunakan untuk mempelajari karakteristik sirkulasi arus eddy di perairan barat laut Indonesia. Metode Winding Angles yang telah dimodifikasi mampu mendeteksi 1663 anticyclonic eddies (AE) dan 1748 cyclonic eddies (CE). Rata-rata umur eddy yang terdeteksi adalah sekitar empat minggu. Mayoritas sirkulasi arus eddy memiliki radius 40 – 100 km dan eddy dengan radius berskala meso (lebih dari 100 km) banyak terkonsentrasi di bagian utara (4° N - 10° N) perairan barat laut Indonesia. Nilai energi kinetik eddy (EKE) bertambah sebanding dengan pertambahan radius, sedangkan nilai vortisitas berbanding terbalik dengan radius. Sirkulasi arus eddy di perairan barat laut Indonesia pada musim timur (JJA) didominasi oleh AE , sedangkan CE mendominasi di musim barat (DJF) dengan periode yang lebih panjang dari November hingga Maret, namun dengan rata-rata radius yang sama setiap bulannya. Pada saat periode di mana kejadian eddy minimum, ditemukan perbedaan letak distribusi meridional eddy bervortisitas tinggi yang menunjukkan CE lebih didukung pembentukannya pada lintang yang lebih rendah daripada AE.
Effect of Liquid Fertilizer on Seedling Enhalus acoroides Seeds (Linnaeus f.) Royle 1839 (Fam: Hydrocharitaceae)

Published: March 2024

The decrease in seagrass coverage and ecosystem harm to seagrass meadows is an annual occurrence resulting from both natural and human activities. Seagrass seeding has been deemed an effective restoration method, but its application is restricted by suboptimal environmental conditions and constraints associated with directly planting seagrass seeds in their natural habitat. The influence of environmental parameters, particularly nutrients, significantly affect on seagrass seed survival. NPK liquid fertilizer is commonly used in aquatic plants and is readily accessible in the market. It serves as a crucial source of macronutrients for seagrass. This study investigates the impact of different concentrations of NPK liquid fertilizer on the survival rate, growth, and chlorophyll, a content of E. acoroides seedlings. The study took place between March and May 2023 at the marine biology laboratory of the marine science study program at Diponegoro University's Faculty of Fisheries and Marine Science. According to the Manova statistical test, the NPK liquid fertilizer had an impact on the growth rate, biomass, and chlorophyll-a. The seagrass seeding container of E. acoroides treated with a liquid fertilizer concentration of 4.5 ml/100l exhibited the highest average growth rate of 0.29 cm/day and a chlorophyll-a value of 12.395 mg/g, with a survival rate of 100%. Causal connections between statements ensure logical construction. In contrast, seedlings without liquid fertilizer treatment showed the lowest growth rate of 0.19 cm/day and chlorophyll-a values of 5.169 mg/g, with a survival rate of 85.19%. Technical term abbreviations such as 'cm/day' and 'mg/g' are explained when first used to ensure clarity. Based on these findings, using liquid fertilizer with a concentration of 4.5 ml/l exhibits potential for restoring seagrass ecosystems.
Simulation approach to study kinetic heterogeneity of gadolinium catalytic system in the 1,4-cis-polyisoprene production
Authors: Miftakhov Eldar , Mustafina Sofia , Akimov Andrey , Mustafina Svetlana 
Published: March 2024

Abstract
This article presents a novel simulation approach for solving the inverse problem of kinetic heterogeneity in polymerization processes, specifically focusing on the production of polyisoprene using a gadolinium chloride solvate-based catalytic system. The proposed method is based on the assumption that the distribution of active centers (ACs) can be described by model distributions. By utilizing primary physicochemical data, such as the polymerization rate and molecular weight distribution, the simulation approach automatically identifies the kinetic parameters, determining the Frenkel statistical parameter and solving the problem of kinetic heterogeneity. The experimental results revealed the presence of at least three distinct types of ACs, each contributing different proportions to the polymerization process. The simulation approach offers valuable insights into the complexities of catalytic systems and their role in polymerization, paving the way for optimizing reaction conditions and advancing industrial polymer synthesis processes. This study marks a significant step forward in understanding and controlling polymerization reactions, with potential implications for the development of innovative materials and industrial applications.

In this paper we prove some generalizations of the classical Hasse–Davenport product relation for certain arithmetic factors defined on a p-adic field F, among them one finds the ϵ-factors appearing in Tate’s thesis.

The molecular and cellular choreography of early mammalian lung development
Authors: Yang Xianfa , Chen Yingying , Yang Yun , Li Shiting , Mi Panpan , Jing Naihe 
Published: March 2024

Abstract
Mammalian lung development starts from a specific cluster of endodermal cells situated within the ventral foregut region. With the orchestrating of delicate choreography of transcription factors, signaling pathways, and cell–cell communications, the endodermal diverticulum extends into the surrounding mesenchyme, and builds the cellular and structural basis of the complex respiratory system. This review provides a comprehensive overview of the current molecular insights of mammalian lung development, with a particular focus on the early stage of lung cell fate differentiation and spatial patterning. Furthermore, we explore the implications of several congenital respiratory diseases and the relevance to early organogenesis. Finally, we summarize the unprecedented knowledge concerning lung cell compositions, regulatory networks as well as the promising prospect for gaining an unbiased understanding of lung development and lung malformations through state-of-the-art single-cell omics.
