A spectrophotometer is a photometer that can measure the intensity of light as a function of its wavelength. Single beam and double beam are the two major classes of spectrophotometers. Linear range of absorption and spectral bandwidth measurement are the important features of spectrophotometers. In Single Beam Spectrophotometers, all the light passes through the sample. To measure the intensity of the incident light the sample must be removed so that all the light can pass through. This type of spectrometer is usually less expensive and less complicated. The single beam instruments are optically simpler and more compact, znc can also have a larger dynamic range. In a Double Beam Spectrophotometer, before it reaches the sample, the light source is split into two separate beams. One beam passes through the sample and the second one is used for reference. This gives an advantage because the reference reading and sample reading can take place at the same time. In transmission measurements, the spectrophotometer quantitatively compares the amount of light passing through the reference and test sample. For reflectance, it compares the amount of light reflecting from the test and reference sample solutions. Many spectrophotometers must be calibrated before they start to analyse the sample and the procedure for calibrating spectrophotometer is known as "zeroing." Calibration is done by using the reference substance, and the absorbencies of all other substances are measured relative to the reference substance. % transmissivity (the amount of light transmitted through the substance relative to the initial substance) is displayed on the spectrophotometer.

Fourier transform infrared spectroscopy (FTIR) is a largely used technique to identify the functional groups in the materials (gas, liquid, and solid) by using the beam of infrared radiations. An infrared spectroscopy measures the absorption of IR radiation made by each bond in the molecule and as a result gives spectrum which is commonly designated as % transmittance versus wavenumber (cm−1). The IR region is at lower energy and higher wavelength than the UV-visible light and has higher energy or shorter wavelength than the microwave radiations. For the determination of functional groups in a molecule, it must be IR active. An IR active molecule is the one which has dipole moment. When the IR radiation interacts with the covalent bond of the materials having an electric dipole, the molecule absorbs energy, and the bond starts back and forth oscillation. Therefore, the oscillation which cause the change in the net dipole moment of the molecule should absorb IR radiations. A single atom doesn’t absorb IR radiation as it has no chemical bond. Symmetrical molecules also do not absorbed IR radiation, because of zero dipole moment. For example, H2 molecule has two H atoms; both cancel the effect of each other and giving zero dipole moment to H2 molecule. Therefore, H2 molecule is not an IR active molecule. On the other hand, HF is an IR active molecule, because when IR radiation interacts with HF molecule, the charge transferred toward the fluorine atom and as a result fluorine becomes partial negative and hydrogen becomes partial positive, giving net dipole moment to H-F molecule. A particular IR radiation will be absorbed by a particular bond in the molecule, because every bond has their particular natural vibrational frequency. For example, a molecule such as acetic acid (CH3COOH) containing various bonds (C-C, C-H, C-O, O-H, and C=O), all these bonds are absorbed at specific wavelength and are not affected by other bond. In general we can say that two molecules with different structures don’t have the same infrared spectrum, although some of the frequencies might be same.

Utilizacin de la inteligencia emocional en el lugar de trabajo Por Kendra Cherry La inteligencia emocional, a veces denominada EQ ("coeficiente emocional"), se refiere a la capacidad de una persona para reconocer, comprender, manejar y razonar con las emociones. Es una habilidad crtica cuando se trata de comunicacin interpersonal, y un tema candente no solo en psicologa, sino tambin en el mundo de los negocios. El trmino fue acuado por psiclogos en la dcada de 1990. Su uso se extendi rpidamente a otras reas, incluidos los negocios, la educacin y la cultura popular. Qu es la inteligencia emocional? Los psiclogos Peter Salovey y John D. Mayer, dos de los principales investigadores en el tema, definen la inteligencia emocional como la capacidad de reconocer y comprender las emociones en uno mismo y en los dems. Esta habilidad tambin implica usar esta comprensin emocional para tomar decisiones, resolver problemas y comunicarse con los dems. Segn Salovey y Mayer, hay cuatro niveles diferentes de inteligencia emocional: Percepcin de emociones Razonamiento con emociones Comprensin de emociones Manejo de emociones En el pasado, las emociones y la inteligencia a menudo se consideraban como opuestas entre s. Sin embargo, en las ltimas dcadas, los investigadores que exploran la psicologa de las emociones se han interesado cada vez ms en la cognicin y el afecto. Esta rea explora cmo los procesos cognitivos y las emociones interactan e influyen en la forma en que las personas piensan. Considere cmo las emociones y los estados de nimo como la felicidad, la ira, el miedo y la tristeza influyen en la forma en que las personas se comportan y toman decisiones. Por qu EQ es importante para el xito El inters en la psicologa de las emociones y el concepto de inteligencia emocional realmente se incendi con la publicacin en 1995 del libro de Daniel Goleman "Inteligencia emocional: por qu puede ser ms importante que el coeficiente intelectual". En el libro, Goleman argument que la inteligencia emocional era fundamental para predecir el xito en la vida. Las competencias emocionales, argument, tambin desempeaban un papel particularmente importante en el lugar de trabajo. El concepto atrajo rpidamente la atencin del pblico, incluidos los gerentes de recursos humanos y los lderes empresariales. Los investigadores han sugerido que la inteligencia emocional influye en la forma en que los empleados interactan con sus colegas, y tambin se cree que EQ juega un papel en la forma en que los trabajadores manejan el estrs y los conflictos. Tambin afecta el desempeo general en el trabajo. Otros estudios han relacionado la inteligencia emocional con la satisfaccin laboral. Los estudios han demostrado que los empleados con puntajes ms altos en las medidas de EQ tambin tienden a obtener una calificacin ms alta en las medidas de funcionamiento interpersonal, habilidades de liderazgo y manejo del estrs. Goleman sugiri que, si bien la inteligencia tradicional estaba asociada con el xit.

Using the information below to answer the following two questions. Chlamydia trachomatis, Chlamydia pneumoniae, and Chlamydia psittaci are three intracellular bacterial pathogens in the same genus. Interestingly, they vary considerably in the diseases they cause. C. trachomatis is a sexually transmitted bacterium that infects the epithelial cells of the genital tract. C. pneumoniae is transmitteed via respiratory droplets from an infected human and can infect the epithelial cells in the throat and the lungs and cause pneumonia. C. psittaci is primarily a pathogen of birds. Within infected birds, the bacterium infects cells in the respiratory tract.These three Chlamydia pathogens all evolved from a common ancestor. How could genetic changes have occurred over time to give rise to these different pathogens?
