Pantoea stewartii subsp. stewartii is a pathogen that causes Stewart wilt on maize. This disease is important in maize. Infection early in growth can cause yield losses of up to 100%. This review examines the history, recent developments, economic impacts and developments of detection technology of Stewart wilt diseases. This paper was created by reviewing several articles relevant to the purpose of the topic. The article's results revealed that the pathogen underwent many changes, including its name, taxonomy, physiological abilities, status as an important pathogen in many countries and the development of detection technology. Currently, P. stewartii subsp. stewartii belongs to the Erwiniaceae family and has physiological abilities that can be distinguished from bacteria of the same genus and species. This pathogen has been reported to spread to more than 82 countries, including Indonesia, with 18 host plants. Some areas have reported pathogens in Indonesia, but no vector has been written. The biggest economic threat caused by this disease is the industrial production of corn seeds which require strict phytosanitary requirements and are free from pathogens. To anticipate its spread, there are four methods of detection of pathogenic bacteria that are commonly used, but serological and molecular detection technologies are the main recommendations.

Aluminum (Al) is one of the problems and is a factor inhibiting plant growth on soils with acidic pH. This study aims to examine the growth response of Eucalyptus pellita and Eucalypus Deglupta seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, where the Al concentration consisted of 5 levels, namely: 0 mM (control), 2 mM, 4 mM, 6 mM, and 8 mM with 3 repetitions each and each repetition consisted of 3 units of the plant. The results showed that Al treatment had a significant effect on the growth parameters of both plant types, except for the root dry weight parameter for E. deglupta. Increasing the Al concentration can reduce almost all growth parameters. The 4 mM Al concentration was able to increase the height growth, plant dry weight (roots and shoots), and tolerance index for the E. pellita species, while the Al 2 mM concentration was able to increase the root growth of E. deglupta plants. Almost all growth parameters for E. pellita species were higher than that of E. deglupta, except for the SPAD chlorophyll index. The concentrations of 6 mM and 8 mM were toxic to E. pellita and E. deglupta.

The progress of a nation is seen from the progress of its education system. If education is a developed country, then the human quality in it is advanced. Therefore education is the most important element in building a nation so that it can be interpreted that the quality of education is the determinant of the quality of a nation. One of the fundamental problems in the world of education is related to the morality of the younger generation. In order to improve the morality of the younger generation who are increasingly concerned today, the Pesantren Education Institute is one of the main choices for parents to educate children to prioritize religious values as the foundation of their children's education. Pesantren is considered as a typical Indonesian Educational Institution that has long existed Indonesia which is believed not only to print a generation of intelligent students but also noble character. With the system applied differently from other public schools, namely the boarding system. The number of students with various social and family economic backgrounds makes the condition of pesantren heterogeneous. Of course, the problems are also diverse, because there is a stereotype in pesantren students who are certainly noble. However, in fact the motives of parents to put children into pesantren not all start from good santri morality, but many students also have problems before and it is expected that pesantren can change the morality of the students

Trim merupakan salah satu kondisi pada kapal dimana terdapat perbedaan draft pada bagian haluan dan buritan. Kapal bergerak dengan kecepatan dinasnya (Vs) pada kondisi normal continuous rating.Pada tahap pendesainan kapal tahanan total kapal (Rt) didapatkan pada kondisi kapal even keel. Namun pada pengoperasianya kapal jarang berada pada kondisi even keel tapi berada pada kondisi trim, baik trim by stern ataupun trim by bow. Penelitian ini ditujukan untuk mendapatkan tahanan total yang minimum dengan variasi trim yang dibuat pada kondisi displasemen 100%, 95%, 90%, 75% dan 55%. Dan juga berapa konsumsi bahan bakar yang dibutuhkan. Untuk dapat melakukan penelitian ini diperlukan pembuatan trim diagram untuk mengetahui variasi trim yang menghasilkan displasemen yang sama. Dan juga dibutuhkan software MAXSURF 11.12 untuk menganalisa tahanan dari variasi trim yang dibuat. Dari hasil penelitian diperoleh bahwa variasi trim yang menghasilkan tahanan total paling minimal adalah trim by stern, namun terdapat satu kondisi dimana tahan total yang paling minimum adalah trim by bow yaitu pada saat kondisi 100% displasemen. Hal ini dikarenakan pada kondisi tersebut area transom pada kapal ketika trim by stern banyak tercelup di dalam air, sedangkan ketika trim by bow hanya sedikit area transom yang tercelup di dalam air. Sehingga menyebabkan tambahan tahanan total pada saat trim by stern. Sedangkan untuk konsumsi bahan bakar yang dibutuhkan berbanding lurus dengan besarnya daya yang dibutuhkan.

A new three-component assembly reaction between N-tosylhydrazones, dihalogenated arenes, and boronic acids or boronate esters was developed, producing highly substituted 1,1-diarylethylenes in good yields. The two C-C bonds formed through this coupling have been catalyzed by a single Pd-catalyst in a one-pot fashion. It is noted that the one-pot pinacol boronate cross-coupling reaction generally provides products in high yields, offers an expansive substrate scope, and can address a broad range of aryl, styrene, vinyl, and heterocyclic olefinic targets. The scope of this one-pot coupling has been also extended to the synthesis of the 1,1-diarylethylene skeleton of the natural product ratanhine. The new compounds were evaluated for their cytotoxic activity, and this allowed the identification of compound 4ab that exhibits excellent antiproliferative activity in the nanomolar concentration range against HCT116 cancer cell lines.

As a result of rapid urbanization in numerous cities around the world, the demand for transportation has increased rapidly, resulting in emission of high levels of exhaust pollutants into the atmosphere. This is a major cause of deterioration in the local air quality, with consequent escalating risk of adverse health conditions amongst urban inhabitants. Understanding dispersion of pollutants in street canyons, local urban configurations, meteorological processes, and other physical factors are essential for predicting and assessing air quality. This article presents a comprehensive review of the state-of-the-art research works relevant to the investigation of flow structures and pollutant dispersion phenomena in urban street canyons. Various factors, including building geometries, local atmospheric conditions, static and dynamic obstructions, as well as chemical reactions of exhaust pollutants, are critically discussed by taking into account field measurements, wind tunnel experiments, operational modeling techniques, and computational fluid dynamics (CFD). The most critical pollutant levels in street canyons under several physical circumstances are identified. Elements leading to discrepancies and resulting in inconsistencies of different research methods are briefly addressed and suggestions for future research are offered. [ABSTRACT FROM AUTHOR]

Pyridylmethylamines or pma are versatile platforms for different catalytic transformations. Five pma-ligands and their respective Pd complexes have been studied by liquid state NMR. By comparing 1H, 13C and 15N chemical shifts for each pma/pma-Pd couple, a general trend for the metallacycle atoms concerns variations of the electronic distribution at the pendant arm, especially at the nitrogen atom of the ligand. Moreover, the increase of the chemical shift of the pendant arm nitrogen atom from primary to tertiary amine is also related to the increase of crowding within the complex. This statement is in good agreement with X-ray data collected for several complexes. Catalytic results for the Suzuki-Miyaura reaction involving the pma-Pd complexes showed within this series that a sterically crowded and electron-rich ligand in the metallacycle was essential to reach the coupling product with a good selectivity. In this context, NMR study of chemical shifts of all active nuclei especially in the metallacycle could give a trend of reactivity in the studied family of pma-Pd complexes.

Abstract: Previous CFD studies on pollution dispersion problems have largely centred on employing Reynolds-averaged Navier–Stokes (RANS) turbulence closure schemes, which have often been reported to overpredict pollutant concentration levels in comparison to wind tunnel measurement data. In addition, the majority of experimental and numerical investigations have failed to account for the aerodynamic effects of trees, which can occupy a significant proportion of typical urban street canyons. In the present work, the prediction accuracy of pollutant dispersion within urban street canyons of width to height ratio, W/H = 1 lined with avenue-like tree plantings are examined using two steady-state RANS models (the standard k-ε and RSM), and Large Eddy Simulation (LES) to compare their performance against wind tunnel experiments available on the online database CODASC . Two cases of tree crown porosities are investigated, one for a loosely (Pvol  = 97.5%) and another for a densely (Pvol  = 96%) packed tree crown, corresponding to pressure loss coefficients of λ = 80 m−1 and λ = 200 m−1, respectively. Results of the tree-lined cases are then compared to a tree-free street canyon in order to demonstrate the impact of trees on the flow field and pollutant dispersion, and it is observed that the presence of trees reduces the in-canyon circulation and air exchange, and increases the overall concentration levels. Between the two numerical methods employed, LES performs better than RANS, because it captures the unsteady and intermittent fluctuations of the flow field, and hence, successfully resolves the transient mixing process within the canyons.
