Bird beak sign - achalasia

AbstrakPenelitian ini berjudul “Sejarah Syair Gulung di Ketapang”. Adapun rumusan masalah dalam penelitian ini adalah bagaimanakah sejarah syair gulung di Ketapang. Hasil penelitian ini diharapkan dapat memberikan kontribusi bagi masyarakat dan peneliti sejarah lokal yang ada di Kalimantan Barat. Penelitian ini adalah penelitian sejarah maka peneliti menggunakan metode sejarah yang ditulis dengan deskriptif analitis dengan langkah atau tahapan, yaitu : 1). Heuristik, 2). Kritik Sumber, 3). Interpretasi, 4). Historiografi. Dalam memperoleh data-data penelitian ini, peneliti menggunakan metode sumber primer, sekunder dan tradisi lisan atau folklor di dalam heuristik dengan menggunakan metode sejarah lisan.Hasil penelitian syair gulung pada awalnya hanyalah sebuah bentuk karangan atau disebut kengkarangan yang berada di Tanah Kayong, Tanah Tanjungpura yang sekarang bernama Kabupaten Ketapang. Ada juga yang menyebutnya Syair Layang karena isinya hanya selayang pandang. Lambat laun berubah menjadi syair gulung dikarenakan ditulis di atas kertas kemudian digulung dan disimpan di dalam parug burung. Isinya berupa bait-bait kata yang mengandung nasehat dan petunjuk hidup kepada masyarakat Melayu. Terdapat tiga fase syair gulung, yakni fase Kerajaan Tanjungpura yang diwakili oleh Syair Pangeran Syarif, fase kedua fase syair gulung jenaka, fase ketiga fase syair gulung berisi kritik sosial. Kata kunci: sejarah, Syair Gulung, Ketapang AbstractThe tittle of of this research is “The history of Syair Gulung”. The main problem of this research is how the history of Syair Gulung in Ketapang. The results of this research hopely could giving a contribution for the mass society and the researchers of local history studies in West Kalimantan. The research is a historical research. The methods of the research is descriptive-analitic includes four stages : 1) heuristic 2) verification 3) interpretation 4) historiography. The methodologies of research have been with a primary source, a secondary source, and oral tradition or folklore in heuristic with the oral history methods.The results of this research is in the beginning with namely of Syair Gulung is Kengkarangan, in Kayong Land, Tanjungpura Kingdom in nowdays becoming popular with Ketapang Regency. The several society knowing Syair Gulung with Syair Layang. At this time people knowing with Syair Gulung due to writed in paper and then rolled up and saved in the bird beak. The contents of Syair Gulung is a stanzas with the advice and life wisdom for Malay societies. The Syair Gulung includes three phases, such as The Tanjungpura Kingdom phase with with Syair Pangeran Syarif, The witty phase, and the social critics phase.

A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic “bird-beak” termination. A Heller myotomy plus fundoplication and endoscopic balloon dilatation were conducted four months previously. Nevertheless, the symptoms persisted and the last high-resolution manometry study still showed achalasia type II. The patient underwent a peroral endoscopic esophageal myotomy (POEM). POEM is a feasible and safe procedure for experienced and properly- equipped health care delivery centers and could be used as a rescue treatment in refr e present the youngest patient with achalasia in our region who had a successful response to rescue POEM.

First Time

Riblet structures found on fast-swimming shark scales, such as those found on a mako shark, have been shown to reduce fluid drag. In previous experimental and modelling studies, riblets have been shown to provide drag reduction by lifting vortices formed in turbulent flow, decreasing overall shear stresses. Skimmer birds ( Rynchops ) are the only birds to catch fish in flight by flying just above the water surface with a submerged beak to fish for food. Because they need to quickly catch prey, reducing drag on their beak is advantageous. For the first time, riblet structures found on the beak of the skimmer bird have been studied experimentally and computationally for low fluid drag properties. In this study, skimmer replicas were studied for drag reduction through pressure drop in closed-channel, turbulent water flow. Pressure drop measurements are compared for black and yellow skimmer beaks in two configurations, and mako shark skin. In addition, two configurations of skimmer beak were modelled to compare drag properties and vortex structures. Results are discussed, and a conceptual model is presented to explain a possible drag reduction mechanism in skimmers. This article is part of the themed issue ‘Bioinspired hierarchically structured surfaces for green science’.
