HOMO and LUMO are acronyms for highest occupied molecular orbital and lowest unoccupied molecular orbital, respectively. The energy difference between the HOMO and LUMO is termed the HOMO-LUMO gap. HOMO and LUMO are sometimes referred to as frontier orbitals.[1] Roughly, the HOMO level is to organic semiconductors what the valence band is to inorganic semiconductors and quantum dots. The same analogy exists between the LUMO level and the conduction band. The atomic orbitals and molecular orbitals pictured above require complicated calculations and assumptions that far exceed the equation shown for ?nlm. Spartan calculates these orbitals as HOMOs or LUMOs. The HOMO (highest occupied molecular orbital) is the valence orbital that received the last valence electron(s). The orbital directly beneath the HOMO in energy is labeled HOMO(-1). The LUMO (lowest unoccupied molecular orbital) is the empty orbital just above the HOMO. The orbital just above the LUMO is labeled LUMO(+1). The \"1\" can be changed to 2, 3, 4, ... to create a complete set of all MOs in the molecule. The HOMO and LUMO images (surfaces) created by Spartan can be correlated/represented with the lines on a molecular orbital (MO) diagram. In this experiment, you will be asked to create the MO diagrams complete with Spartan orbital surfaces for H2 + , H2, and H2 - . Spartan also can generate electron density surfaces. Electron density is the square of the wave function (|?| 2 , or |?| 2 ). Squaring the wave function results in the loss of phase information (i 2 = - 1). The lack of phase information is indicated in Spartan by the creation of gray only density surfaces (Note: the \"electron\" is omitted in Spartan). The surface created represents the relative size and shape of the molecule, atom, or ion being investigated.

Toxic shock syndrome (TSS) is a toxin-mediated acute life-threatenin.pdf

angelcolluctions

Toxic shock syndrome (TSS) is a toxin-mediated acute life-threatening illness, usually precipitated by infection with either Staphylococcus aureus or group A Streptococcus (GAS), also called Streptococcus pyogenes. It is characterized by high fever, rash, hypotension, multiorgan failure (involving at least 3 or more organ systems), and desquamation, typically of the palms and soles, 1-2 weeks after the onset of acute illness. The clinical syndrome can also include severe myalgia, vomiting, diarrhea, headache, and non focal neurologic abnormalities. Toxic shock syndrome toxin 1(TSST-1), a prototype superantigen secreted by a Staphylococcus aureus bacterium strain in susceptible hosts, acts on the vascular system by causing inflammation, fever, and shock.This bacterium strain that produces the TSST-1\'s can be found in any area of the body. TSST-1 is a bacterial exotoxin found in patients who have developed toxic shock syndrome (TSS), which can be found in menstruating women or any man or child for that matter. GAS is an aerobic gram-positive organism that forms chains and is an important cause of soft tissue infections. Diabetes, alcoholism, varicella infections, and surgical procedures all increase the risk of severe GAS infections and hence may potentially increase the risk of GAS TSS. Severe, invasive GAS infections can cause necrotizing fasciitis and spontaneous gangrenous myositis. An increasing number of severe GAS infections associated with shock and organ failure have been reported. These infections are termed streptococcal TSS. Toxic shock syndrome toxin (TSST) is a superantigen with a size of 22 kDa produced by 5 to 25% of Staphylococcus aureus isolates. It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumour necrosis factor. In general, the toxin is not produced by bacteria growing in the blood; rather, it is produced at the local site of an infection, and then enters the blood stream. Pathogensis: M proteins: Filamentous proteins on the cell membrane with antiphagocytic properties. More than 80 M types.

The trophozites (active form) are present only in the host and fresh loose faeces. E. coli is found in the faeces of the carrier. In unsanitary conditions (like open defecation), the cysts are released and they may be persistent for a few months in the environment. When a person drinks untreated water contaminated with E. coli, the cysts enter his digestive system. once inside the digestive system, the cysts release the trophozite stage within the digestive tract which may lead to further infection. the trophozites are generally present in the large intestine. Sometimes, they invade the intestinal mucosa, enter the blood stream and pass on to the different parts of the body causing a number of outcomes, the most common of which is liver abcess.

Superior colliculus/optic tectum is a midbrain structure. The term superior colliculus is used when discussing mammals and optic tectum when discussing either specific non-mammalian species or vertebrates in general. It is a layered structure, with a number of layers that varies by species. The layers can be grouped into the superficial layers and the deeper layers. Neurons in the superficial layers receive direct input from the retina and respond almost exclusively to visual stimuli. The deeper layers contain a population of motor-related neurons, capable of activating eye movements as well as other responses. The superior colliculus mainly has its role in directing eye movements. Visual input from the retina, or an input from the cerebral cortex, creates a \"bump\" of activity in the tectal map, which, if strong enough, induces a saccadic eye movement (A quick and simultaneous movement of both eyes). In primates however, the superior colliculus is also involved in generating spatially directed head turns, arm-reaching movements, and shifts in attention that do not involve any overt movements. In other species, the tectum is involved in a wide range of responses, including whole-body turns etc. Solution Superior colliculus/optic tectum is a midbrain structure.

One major similarity with soils dominated by calcium and sodium ions.pdf

angelcolluctions

One major similarity with soils dominated by calcium and sodium ions are that they will be saline soils without much moveable waer within them and plants would have to apply more energy to exude salts and take up pure water. The main difference is sodium ions will disperse into separate particles rather than sticking together. In terms of affecting water flow and hydrology in soils, the most important impact of high Na+ is that aggregates will be weaker or nonexistent if they are held together by clay. Without aggregation pore structure of soil is highly affected and it is seen that water drainage doesnt take place as fast as that in calcium rich soils. Calcium ions have a tendency to ‘flocculate’ (clump together) soil colloids (fine clay and organic matter particles), thus, increasing aggregation and macroporosity.In turn, soil porosity, structural stability and water movement may actually be improved in saline soils.

H2SO4 is stronger than HSO4- since HSO4 already has one negative cha.pdf

angelcolluctions

H2SO4 is stronger than HSO4- since HSO4 already has one negative charge - gaining a second is unfavorable compared to H2SO4 which would gain only a -1 charge after deprotonation. HNO3 is stronger than HNO2 since the greater number of O atoms exerts a stronger electron- withdrawing effect on the O-H electrons. Additionally, the NO3- ion has more resonance structures and thus greater resonance stability than the NO2- ion. H2S is a stronger acid than H2O since hydrogen forms weaker bonds to elements lower in the periodic table (larger elements). This is why HI is stronger than HBr, for example. H2S is a stronger acid than PH3 since S is more electronnegative (further to the right in the periodic table) than P. Thus, S prefers to have a negative charge compared to P. For part 2: We know that Kw = [H3O*][OH-] = 10^- 14 M. In pure water, these ions are at equal concentrations, so [H+] = [OH-] = 10^-7 M. Now, we have 1.00 mL = 0.001 L. So, we have 10-7 mol/L * 0.001 L = 10^-10 moles of each ion. Now, 1 mol = 6.02 * 10^23 ions, so we have: 6.02*10^23 * 10^-10 = 6.02 * 10^13 [H3O*] ions and 6.02 * 10^13 [OH-] ions.

A) Germ cell specification in Drosophila occurs by maternally contributed determinants. In Drosophilla, germ cells can easily be identified very early in embryogenesis, when their differentiation as germ cells is assured by the localisation of maternally inherited determinants before, or immediately following, fertilisation. During oogenesis in Drosophila melanogaster, RNAs and proteins are synthesised by the nurse cells. These products are transported through cytoplasmic bridges to the oocyte where They become localised to the posterior of the ooplasm both by molecular anchoring at the posterior of the oocyte, and by posterior-specific translational and transcriptional regulation. This posterior ooplasm is the germ plasm, or germ line determinant. During early embryogenesis, cells which inherit the germ plasm become the primordial germ cells. One of the important gene that contributes to germ cell specification in Drosophila is Nanos. b) Neural crest cell specification is due to the cell signalling and depends on BMP signalling in the prospective epidermis and Wnt signalling from the underlying mesoderm. C) Anterior -posterior specification in Drosophila is initiated by maternal effect genes that produce messenger RNA that are placed in different regions of egg . These mRNA encode transcriptional and translational regulatory protiens that diffuse through the syncytial blastoderm and activates or repress the expression of certain zygotic genes. One important maternal effect gene in this respect is bicoid gene. Solution A) Germ cell specification in Drosophila occurs by maternally contributed determinants.
