This document describes using open source tools for cross development on ST microcontrollers from the STR710, STR730 and STR750 families. It discusses the necessary hardware, including a target board with the microcontroller, a JTAG interface to connect the board to a PC, and the software tools used, such as OpenOCD, GNU ARM Eclipse and Insight. It then provides tutorials for setting up the tools on Windows and Linux, covering installing software, configuring projects, building and debugging programs. Details are given on the configuration files and project template created by the authors to support development. Tests were also done with an STR912 board which showed promising results.
La carta enfatiza la importancia de especializarse, recordar consejos valiosos, y mantener la esperanza para el futuro. También expresa el deseo de que la persona nunca olvide su valía.
Using Audio Podcasts To Enhance Learning PresentationRita Mae Santos
Podcasting involves automatically downloading media files from the web to listen to offline on devices like computers or MP3 players. It allows for radio-quality content to be listened to anytime, anywhere, and enables teachers to engage students through a popular medium. Podcasting has the potential to advance education beyond the classroom in a flexible, accessible way. However, large file sizes can make downloads slow, and ensuring accessibility and avoiding copyright issues requires care.
Condivisione dei file, apertura di una shell sul computer remoto ed (eventualmente) esecuzione di applicazioni grafiche (SSH), accesso alla sessione grafica corrente da remoto (VNC) e sicurezza tramite SSH, apertura di una nuova sessione grafica su server Mac OS X, Windows e Linux, NX e FreeNX, il reverse port forwarding, problemi pratici e soluzioni

This document discusses improving the usability of open source software. It explores options for developing graphical user interfaces for open source projects. Developers can work on existing open source projects or start new ones focused on areas like operating systems, applications, frontends, configuration files, or translations. Popular graphical libraries like GTK+ and Qt can be used to develop GUIs, and bindings exist for languages like Python, Perl, and C++. Tools like Glade and Qt Designer allow visual design of user interfaces. Frameworks like wxWidgets aim to create truly cross-platform applications with native looks and feels. The document provides examples of "Hello World" programs using different libraries and languages.
The document reflects on the author's past four years which included a variety of technical skills and work. It discusses choices in life and topics like communication, management, survival, happiness, responsibility, family, love, and making the most of the one life you have.
This document provides an overview of web development using technologies like PHP, jQuery, AJAX, Comet and HTML5. It discusses client/server architecture and how web applications use a traditional three-tier model. It also outlines and describes key server-side technologies like PHP and client-side technologies like JavaScript, how they interact with documents using the DOM, and how jQuery can be used to simplify DOM manipulation and AJAX requests.
Neurochemistry of defensive behavior in zebrafishCaio Maximino
This document discusses research on the neurochemistry of defensive behaviors in zebrafish. It summarizes several studies that investigated the role of adenosine, serotonin, glutamate, and nitric oxide in behaviors related to anxiety in zebrafish such as scototaxis and geotaxis. The document also proposes a model for studying post-traumatic stress disorder in zebrafish and summarizes initial findings showing stress-induced sensitization of defensive behaviors that could be blocked by inhibitors of nitric oxide synthase. Future directions are outlined, including more mechanistic electrophysiology and localization of the neural responses.

Pengaruh ukuran simplisia teh hitam ( camelia sinensis) terhadap kandungan ka...AikaAjiNababan
Penelitian ini menguji pengaruh ukuran partikel simplisia teh hitam terhadap rendemen ekstrak dan kandungan kafein. Simplisia teh hitam diayak dengan ukuran mesh 20, 40, 60 dan utuh, lalu diekstraksi dengan etanol dan air. Hasilnya, ukuran mesh 60 memiliki rendemen dan kandungan kafein tertinggi karena memiliki luas permukaan kontak terbesar dengan pelarut.
Dokumen tersebut membahas proses pra-panen, panen, dan pasca-panen dari teh, kopi, dan coklat. Mulai dari proses fotosintesis, pembentukan senyawa kimia seperti kafein, teobromin, dan katekin hingga proses pengolahan setelah panen seperti fermentasi untuk teh dan sorting untuk ketiganya.
Ebastine mengalami metabolisme panjang oleh enzim sitokrom P450 di hati manusia untuk membentuk metabolit hidroksi dan dealkilebastine, kemudian metabolit lanjutan carebastine. Studi menunjukkan bahwa CYP2J2 berperan utama dalam hidroksilasi ebastine, sedangkan CYP3A4 berperan utama dalam dealkilasi ebastine dan metabolitnya. Temuan ini berguna untuk memahami interaksi obat ebastine in vivo.
Ringkasan dokumen tersebut adalah:
1. Penelitian ini menentukan kadar flavonoid total ekstrak etanol daun cengkeh dengan menggunakan metode spektrofotometri UV-Vis.
2. Hasil ekstraksi daun cengkeh menghasilkan rendamen sebesar 16,1134% dan kadar flavonoid totalnya adalah 73,08 mgRE/g ekstrak atau setara 7,308%.
3. Penelitian ini menggunakan metode maserasi dengan pelarut
Penelitian ini mengukur kandungan flavonoid total, khususnya kuersetin, pada ekstrak etanol daun kelor dengan metode kromatografi lapis tipis densitometri. Hasilnya menunjukkan bahwa rendemen ekstrak etanol daun kelor adalah 13,65% dan kandungan flavonoid totalnya adalah 0,45 gram per 100 gram ekstrak.
