Analisis Tata Kelola Maritim Indonesia: Implementasi Visi Pemerintah Daerah Istimewa Yogyakarta
No full textIndonesia sebagai negara maritim memiliki banyak peluang dan ancaman. Hal tersebut memerlukan adanya perhatian yang lebih besar terhadap wilayah laut. Penelitian ini membahas strategi Pemerintah Indonesia untuk meningkatkan peluang ekonomi dan mengatasi tantangan melalui Poros Maritim Dunia. Tujuan riset ini adalah menganalisa kebijakan Pemerintah Indonesia dan Pemerintah Provinsi Daerah Istimewa Yogyakarta (DIY) dalam pengembangan wilayah pesisir menggunakan teori geopolitik dan teori kekuatan laut. Penelitian ini menerapkan metode kualitatif studi kasus. Data yang digunakan berupa data primer melalui wawancara dan data sekunder yang diperoleh dari buku, artikel jurnal dan publikasi daring. Penulis menemukan bahwa sinergitas penegak hukum, diplomasi maritim sudah cukup baik, namun perlu lebih aktif melibatkan masyarakat untuk pengelolaan sumber daya hayati yang berkelanjutan dan peningkatan SDM masyarakat pesisir. Sementara Visi Gubernur DIY bernama Abad Samudera Hindia belum terlaksana dengan maksimal. Masyarakat membutuhkan tambahan pembangunan TPI baru dan pengembangan TPI menjadi PPN dan PPS untuk meningkatkan produktivitas dan kesejahteraan nelayan. Dapat disimpulkan bahwa pemerintah pusat dan daerah harus selalu memperhatikan pengelolaan laut, khususnya untuk pemanfaatan sumber daya dan pangan. Bahwa laut memiliki kekayaan alam yang berlimpah dapat digunakan meningkatkan gizi masyarakat dan pendapatan negara. Title: Indonesian Maritime Governance Analysis: Implementation of the Vision of the Yogyakarta Special Region GovernmentIndonesia, as a maritime country, has many opportunities and threats. This condition requires greater attention to the sea area. This research discusses the strategy of the Government of Indonesia to increase economic opportunities and overcome challenges through the World Maritime Fulcrum. This research aims to analyze the policies of the Government of Indonesia and the Provincial Government of DIY in developing coastal areas using geopolitical theory and the theory of sea power. This study uses a qualitative case study method. The data used are primary data through interviews and secondary data obtained from books, journal articles and online publications. The author finds that the synergism between law enforcement and maritime diplomacy is good enough. However, it is necessary to involve the community more actively in the sustainable management of biological resources and to increase the human resources of coastal communities. Meanwhile, the vision of the Governor of DIY called the Century of the Indian Ocean, has not been implemented optimally. The community needs additional construction of new TPI and development of TPI to become PPN and PPS to increase the productivity and welfare of fishermen. It can be concluded that the central and regional governments must always pay attention to marine management, especially for utilising resources and food. That the sea has abundant natural wealth can be used to improve people’s nutrition and state income
Role of a heart valve clinic programme in the management of patients with aortic stenosis.
No full textpeer reviewedAIMS: We sought to assess the efficacy of a heart valve clinic (HVC) follow-up programme for patients with severe aortic stenosis (AS). METHODS AND RESULTS: Three hundred and eighty-eight consecutive patients with AS (age 71 +/- 10 years; aortic-jet velocity 5.1 +/- 0.6 m/s) and an indication for aortic valve replacement (AVR) were included. Of these, 290 patients presented with an indication for surgery at their first visit at the HVC and 98 asymptomatic patients who had been enrolled in an HVC monitoring programme developed indications for surgery during follow-up. Time to symptom detection was significantly longer in patients that presented with symptoms at baseline (352 +/- 471 days) than in patients followed in the HVC (76 +/- 75 days, P /=III) was present in 61% of patients being symptomatic at the initial visit and in 34% of patients in the HVC programme (P < 0.001). CONCLUSION: Delays in referral and symptom reporting as well as symptom denial are common in patients with AS. These findings support the concept of risk stratification to identify patients who may benefit from elective surgery. A structured HVC programme results in the detection of symptoms at an earlier and less severe stage and thus in an optimized timing of surgery

No full textgraficas, ilustraciones, tablasEl desarrollo de nuevos procesos es un tema de gran interés para la ingeniería de reactores, ya que se hace necesario mejorar e implementar nuevas prácticas en la industria que garanticen un futuro sostenible mediante la transformación de diferentes materiales. En general, la aplicabilidad de estos procesos a escala comercial está limitada por la complejidad de las reacciones en serie que se dan y las tecnologías de baja eficiencia, lo que conduce a que sean económicamente inviables. Por lo tanto, es necesario un profundo conocimiento del proceso y su operatividad para proponer tecnologías innovadoras que contribuyan a superar las restricciones mencionadas, mejorando así la incorporación de nuevos procesos para la transformación de materiales lignocelulósicos. En esta disertación, se desarrolló un nuevo concepto de reactor percolador para la producción y extracción de azúcares como: xilosa, glucosa, manosa, arabinosa y galactosa o subproductos como el furfural. Este proceso se desarrolló utilizando desechos biodegradables como la hoja de mazorca debido a que un material económico y de alta disponibilidad en Colombia.
El análisis del reactor se realizó en tres etapas: el modelamiento del reactor percolador mediante el software de Matlab® y la integración de este modelamiento con sección experimental para obtener los parámetros cinéticos que modelan la hidrólisis de la hemicelulosa y finalmente optimización de las concentraciones de los azúcares.
En la etapa del modelamiento del reactor percolador, se obtuvieron las ecuaciones del balance de masa que predecían las concentraciones de los productos y subproductos de la descomposición de la hemicelulosa de la hoja de mazorca. Para la obtención del modelamiento se realizó una caracterización del material lignocelulósico, obteniendo así los porcentajes de hemicelulosa, celulosa y lignina presentes en la materia para ser adaptados al modelo. El modelamiento del reactor percolador se desarrolló mediante el software Matlab®, utilizando una subrutina de optimización global y el comando fmincon para minimizar la función objetivo que consistía en minimizar la sumatoria de los residuales al cuadrado.
Una vez obtenido el modelamiento, éste se ajustó con los resultados de los datos experimentales de la hidrólisis de la hoja de mazorca. El ajuste del modelo del reactor percolador se realizó mediante un diseño secuencial obteniéndose la estimación de parámetros cinéticos, para esto primero se seleccionó las condiciones iniciales experimentales, luego se ajustaron los parámetros, seguidamente se utilizó el modelo secuencial para la predicción de nuevas condiciones de operación. Se hizo necesario la verificación de la calidad de la predicción del modelo (varianza de los parámetros del modelo), donde la varianza se ajustó a un valor máximo del 6%, para termina el proceso de ajuste.
Finalmente, con los parámetros cinéticos ajustados, se optimizaron las ecuaciones de los balances que mostraban el comportamiento de la producción de azúcares para obtener concentraciones máximas de xilosa y furfural, por medio de nuevas rutinas de software Matlab®, con el comando fmincon. La productividad del sistema fue más alta que la obtenida en otros reactores para hidrólisis de este tipo de materiales. El desempeño obtenido con estos reactores muestra el potencial de la tecnología desarrollada y es la fuerza impulsora para continuar investigando la optimización de los procesos. (Texto tomado de la fuente)The development of new processes is a topic of great interest for reactor engineering, since it is necessary to improve and implement new practices in the industry that guarantee a sustainable future through the transformation of different materials. The applicability of these processes on a commercial scale is limited by the complexity of the series reactions involved and the low efficiency technologies, which leads to their economic unfeasibility. Therefore, a deep knowledge of the process and its operability is necessary to propose innovative technologies that contribute to overcome the mentioned restrictions, thus improving the incorporation of new processes for the transformation of lignocellulosic materials. In this dissertation, a new concept of percolator reactor was developed for the production and extraction of sugars such as xylose, glucose, mannose, arabinose and galactose or by-products such as furfural. This process was developed using biodegradable wastes such as corncob leaves because it is an inexpensive and highly available material in Colombia.
The reactor analysis was carried out in three stages: modeling of the percolator reactor using Matlab® software and integration of this modeling with experiments to get the kinetic parameters that model the hydrolysis of hemicellulose and finally optimization of the product concentrations.
In the modeling stage of the percolator reactor, mass balance equations were derived to predict the concentrations of the products and by-products from the decomposition of the hemicellulose of the corncob leaf. For the simulation model, a characterization of the lignocellulosic material was performed to measure the percentages of hemicellulose, cellulose, and lignin present in the material to be included in the model. The modeling of the percolator reactor was developed using Matlab® software, using a global optimization subroutine and the fmincon command to minimize the objective function that consisted of minimizing the sum of the squared residuals.
The simulation model was adjusted with the results of the experimental data of the hydrolysis of the cob leaf. The parameters were fitted by a sequential design of experiments, first the initial experimental conditions were selected, then the parameters were adjusted, then the sequential model was used for the prediction of new operating conditions for the next experimental. It was necessary to verify the quality of the model prediction (variance in the model parameters). The variance was adjusted to a value of 5%.
Finally, with the model of the percolator reactor, the operating conditions were optimized to attain maximum concentrations of xylose and furfural. The productivity of the percolator reactor is higher than the one reached by other reactors for hydrolysis of this type of materials. The performance of a percolator reactor is superior to the conventional batch and plug flow reactors.MaestríaMagíster en Ingeniería - Ingeniería QuímicaQuímica Y Procesos.Sede Manizale
