Pres3tlenonAtoms are made up of electrons that orbit around a small, positively charged nucleus. J.J. Thomson discovered that electrons come from atoms and are much smaller than atoms. Rutherford found that atoms are mostly empty space by shooting radioactive particles at atoms and observing some bounce off, indicating a small, dense nucleus. Bohr incorporated Rutherford's nuclear model and proposed that electrons can only orbit in certain fixed distances from the nucleus, known as orbitals.
Applied Chapter 3.3 : Electron ConfigurationChris FoltzThe document discusses electron configuration and the quantum models of the atom. It compares the Rutherford, Bohr, and quantum models. It explains the four quantum numbers - principal, angular momentum, magnetic, and spin quantum numbers. It describes how light emission spectra provide information about an atom's energy levels. Rules for writing electron configurations are given, including the Aufbau principle, Pauli exclusion principle, and Hund's rule. Orbital notation, electron configuration notation, and noble gas notation are defined. Examples are provided of writing the electron configuration for atoms with specific atomic numbers.

It describes key experiments and contributions from Thomson, Rutherford, and Bohr that led to advances in understanding the structure of the atom, including Thomson discovering the electron, Rutherford showing the nucleus, and Bohr incorporating quantum theory. The models progressed from electrons distributed in a positive cloud to orbiting a dense nucleus to orbiting in discrete shells.

The objectives will help students explain atomic structure and properties using concepts from electricity, nuclear physics, and quantum mechanics.
4structureoftheatomRajan PvThe document discusses the structure of atoms. It explains that atoms contain protons, neutrons and electrons. The atomic model has evolved over time from Thomson's "plum pudding" model to Rutherford's discovery of the nucleus at the center of the atom, to Bohr's model of electrons in discrete orbits. It further discusses the distribution of electrons in different shells, an element's valency which is determined by its outer shell electrons, atomic and mass numbers, isotopes and isobars.

DINTO An Ontology for Drug-Drug InteractionsGrupo HULATThis document describes DINTO, an ontology for representing drug-drug interaction (DDI) information. It summarizes that DINTO systematically organizes all DDI related information, differs from other drug ontologies by representing pharmacological aspects of drugs and DDIs, and represents both pharmacodynamic and pharmacokinetic mechanisms. The current version of DINTO was created manually and represents general pharmacological principles of DDIs, while future versions will also automatically represent specific DDIs between drug pairs through integration with other ontologies. An example use case demonstrates how DINTO represents a pharmacokinetic DDI between cyclosporine and rosuvastatin.

An introduction to htmlkashifareedThe document explains that HTML is the markup language used to define web pages. It describes some basic HTML tags like <html>, <head>, <title>, <body>, <h1>, and <p> that are used to define the structure and content of an HTML document. It also provides a simple example of an HTML page using these tags, and explains that HTML documents are composed of nested tags that describe different types of content.

Detecting Drugs and Adverse Events from Spanish Health Social Media StreamsGrupo HULATAuthors: Isabel Segura-Bedmar, Ricardo Revert, Paloma Martínez
Louhi 2014 (The Fifth International Workshop on Health Text Mining and Information Analysis). Gothenburg, Sweden (April 27, 2014) (http://dsv.su.se/en/research/research-areas/language/description/louhi-2014-1.154970)
Abstract: To the best of our knowledge, this is the first work that does drug and adverse event detection from Spanish posts collected from a health social media. First, we created a gold-standard corpus annotated with drugs and adverse events from social media. Then, Textalytics, a multilingual text analysis engine, was applied to identify drugs and possible adverse events. Overall recall and precision were 0.80 and 0.87 for drugs, and 0.56 and 0.85 for adverse events.

Ultra low dielectric, self-cleansing and highly oleophobic POSS-PFCP aryl eth...Babloo Sharma, Ph.D.Ultra low dielectric constant (k 1⁄4 1.53) materials with self-cleansing properties were synthesized via incorporation of fluorodecyl-polyhedral oligomeric silsesquioxane (FD-POSS) into recently synthesized perfluorocyclopentenyl (PFCP) aryl ether polymers. Incorporation of fluorine rich, high free volume, and low surface energy POSS into a semifluorinated PFCP polymer matrix at various weight percentages resulted in a dramatic drop in dielectric constant, as well as a significant increase in hydrophobicity and oleophobicity of the system. These ultra-low dielectric self-cleansing materials (qtilt 1⁄4 38) were fabricated into electrospun mats from a solvent blend of fluorinated FD-POSS with PFCP polymers.
2. Introdueix la idea de la discontinuïtat de la
matèria, és a dir, aquesta és la primera teoria
científica que considera que la matèria està
dividida en àtoms (deixant a part a precursors de
l'Antiguitat com Demòcrit i Leucip, les afirmacions
no es recolzaven en cap experiment rigorós ).
Els postulats bàsics d'aquesta teoria atòmica
són:
1. La matèria està dividida en unes partícules
indivisibles i inalterables, que s'anomenen àtoms.
2. Tots els àtoms d'un mateix element són idèntics
entre si (presenten igual massa i iguals
propietats).
3. Els àtoms de diferents elements tenen diferent
massa i diferents propietats.
4. Els compostos es formen quan els àtoms
s'uneixen entre si, en una relació constant i
senzilla.
