description: Рассматривается технологический цикл изготовления активного элемента рНЕМТ-транзистора с длиной затвора 0,25 мкм в составе СВЧ монолитной интегральной схемы на арсениде галлия. Основной областью применения этой технологии является проектирование монолитных интегральных схем с рабочими частотами до Ku-диапазона (18 ГГц). Разработаны требования к уровню основных параметров интегрального рНЕМТ-транзистора. В качестве исходной гетероструктуры выбрана рНЕМТ-структура с двухсторонним наполнением канала электронами — DpHEMT-структура, обеспечивающая низкие значения коэффициента шума и высокий уровень удельной выходной СВЧ-мощности. Рассмотрены способы формирования металлизации Т-образного затвора, улучшающие адгезию наносимой в дальнейшем пассивирующей пленки SiO2. Проведен анализ конструкций подзатворных канавок СВЧ рНЕМТ-транзисторов. Методами ИК Фурье-спектроскопии исследована структура низкотемпературных плёнок SiO2, полученных химическим осаждением из газовой фазы. Для устранения дефицита по кислороду в пленках использовался фотонный отжиг.

description: We report on the masses ($M_\mathrm{WD}$), effective temperatures ($T_\mathrm{eff}$) and secular mean accretion rates ($\langle \dot{M} \rangle$) of 43 cataclysmic variable (CV) white dwarfs, 42 of which were obtained from the combined analysis of their $\mathit{Hubble~Space~Telescope}$ ultraviolet data with the parallaxes provided by the Early Third Data Release of the $\mathit{Gaia}$ space mission, and one from the white dwarf gravitational redshift. Our results double the number of CV white dwarfs with an accurate mass measurement, bringing the total census to 89 systems. From the study of the mass distribution, we derive $\langle M_\mathrm{WD} \rangle = 0.81^{+0.16}_{-0.20}\,\mathrm{M_\odot}$, in perfect agreement with previous results, and find no evidence of any evolution of the mass with orbital period. Moreover, we identify five systems with $M_\mathrm{WD} < 0.5\mathrm{M_\odot}$, which are most likely representative of helium-core white dwarfs, showing that these CVs are present in the overall population. We reveal the presence of an anti-correlation between the average accretion rates and the white dwarf masses for the systems below the $2-3\,$h period gap. Since $\langle \dot{M} \rangle$ reflects the rate of system angular momentum loss, this correlation suggests the presence of an additional mechanism of angular momentum loss that is more efficient at low white dwarf masses. This is the fundamental concept of the recently proposed empirical prescription of consequential angular momentum loss (eCAML) and our results provide observational support for it, although we also highlight how its current recipe needs to be refined to better reproduce the observed scatter in $T_\mathrm{eff}$ and $\langle \dot{M} \rangle$, and the presence of helium-core white dwarfs.

title: Development of an Enzyme Linked Immunosorbent Assay Capable of Detecting Antibodies Specific to the Cytomegalovirus
Creators: name: Bird, Rachel
Publisher: name: Utah State University
Year: 1996

description: The cytomegalovirus (CMV) is capable of causing serious illness and death in immunocompromised individuals. The objective of this research is to develop a method of detecting antibodies against CMV. This has lead to the development of an Enzyme linked Immunosorbent Assay (ELISA) that is capable of detecting CMV or anti-CMV antibodies. The process in the development of such an assay involves; 1) the purification of Hyperimmune Rabbit Serum containing anti-CMV antibodies, 2) determination of the appropriate concentrations necessary to provide a clear and concise response to the test, and 3) testing of monoclonal antibodies to determine their specificity towards the cytomegalovirus.

description: We apply the standard technique of Null Melvin Twist to the non-extremal (D1, D3) bound state configuration of type IIB string theory. Under a particular decoupling limit, such configuration represents the gravity dual of the non-relativistic, non-commutative Yang-Mills theory at a finite temperature. We then use the AdS/CFT and the string probe approach to compute the drag force on an external quark moving through such a hot non-relativistic, non-commutative YM plasma. We discuss various limiting cases to show the interplay between the non-relativistic as well as the non-commutative effect of the general drag force expression.

The committeemen of Norfolk and Bedfordshire, 1642-1660
Creators: name: Martin, William Stanley
Publisher: name: University of British Columbia
Year: 2010

description: This study of Norfolk and Bedfordshire in the civil war and Interregnum was based on an analysis of the membership of the various committees appointed for the counties between December 1642 and March 1660. The members of the committees were divided into groups for analysis according to the dates of their first and last appointments. The gentry of Norfolk and Bedfordshire, which were both Parliamentarian counties, filled the committees of the 1640s, as they had the commissions of the peace in the 1630s. After the execution of the King in January'' 1649, the membership of the Bedfordshire committees was drastically changed by the loss of almost all the gentry members, while the Norfolk committees remained largely unchanged until I65I-I652. The difference between the counties was traced to the displacement of the secluded MPs- from the committees; the probably voluntary withdrawal of the Bedfordshire gentry; the weaker and more fluid gentry community and the greater penetration of radical political and religious ideas in Bedfordshire. Throughout the 1650s, Bedfordshire was administered by people new to county office, of lower social rank and more radical opinions than their gentry predecessors• Similar new people became important in Norfolk after I65I, but they did not replace the gentry, who retained their role and influence. In late 1659 and early 1660, the gentry in both counties returned to sole control of local government, displacing the new officials of the 1650s. A similar pattern in the type of committeemen was observed in both counties: the committeemen appointed before 1649 and in 1660 were of the same social rank as those holding county office before 1640, but the committeemen appointed for the first time I649-I656 were of markedly lower social origins. It was noted that in Bedfordshire, and to a much lesser extent in Norfolk, these new officials of the 1650s proved a viable alternative administration to the traditional gentry elite.
title: Optimization of Torquer Coil Design for Use With the Small Satellite Attitude Control Simulator
Creators: name: Anderson, David Deloyd
Publisher: name: Utah State University
Year: 1996

description: This paper presents a procedure used to optimize the performance of a ferromagnetic core magnetic torquer coil design for use on the Space Dynamics Laboratory (Logan, UT) Small Satellite Attitude Control Simulator. The items of optimization include the primary goal of maximizing the coil 's magnetic moment while reducing power consumption and system mass within given power, mass, and dimensional constraints. The optimization process makes use of several simple equations to determine a few starting points for design, after which an iterative approach based on experimentation is used to produce the final design. It is found that optimal magnetic moment performance requires the wise use of as much mass as is available. It is also found that power consumption can be greatly reduced by increasing the length of wire used, at a negligible cost to magnetic moment performance and a small increase in total mass. General governing equations are also compiled to help the reader understand the interplay between the wire windings and the ferromagnetic core in determining performance, and may also serve as starting point in developing performance predicting computer models.
Orbit decay of 2-100 au planetary remnants around white dwarfs with no gravitational assistance from planets

description: A widely-held assumption is that each single white dwarf containing observable rocky debris requires the presence of at least one terrestrial or giant planet to have gravitationally perturbed the progenitor of the debris into the star. However, these planets could have been previously been engulfed by the star or escaped the system, leaving behind asteroids, boulders, cobbles, pebbles, sand and dust. These remaining small bodies could then persist throughout the host star's evolution into a white dwarf at ~2-100 au scales, and then be radiatively dragged into the white dwarf without the help of a planet. Here we identify the parameter space and cooling ages for which this one metal-pollution mechanism is feasible by, for the first time, coupling Poynting-Robertson drag, the Yarkovsky effect and the YORP effect solely from rapidly dimming white dwarf radiation. We find that this no-planet pollution scenario is efficient for remnant 10^{-5}-10^{-4} m dust up to about 80 au, 10^{-4}-10^{-3} m sand up to about 25 au and 10^{-3}-10^{-2} m small pebbles up to about 8 au, and perhaps 10^{-1}-10^{0} m small boulders up to tens of au. Further, young white dwarf radiation can spin up large strength-less boulders with radii 10^{2}-10^{3} m to destruction, breaking them down into smaller fragments which then can be dragged towards the white dwarf. Our work hence introduces a planet-less metal-pollution mechanism that may be active in some fraction of white dwarf planetary systems.

description: Determining the most reasonable LED spectral composition wavelengths on Sinningia speciosa transplants was the main focus of present experiment. Seeds were sown in cell trays under chambers with distinct spectral composition including white+blue+red (WBR), blue+red (BR) and white+red (WR) LEDs with equal light quality proportions (70 µmol m­-2 s-­1 photon ﬂux density) and under sunlight (400 µmol m­-2 s­-1 photon ﬂux density) in constant conditions of 14h photoperiod, 70% relative humidity and day/night temperature of 23/18°C for 50 days. In this stage, LED treatments led to higher germination percentage and better results in biomass, canopy width, leaf width and leaf area as well as chlorophyll and carotenoids accumulation were obtained in comparison with sunlight. Extracted and technical parameters of chlorophyll ﬂuorescence induction kinetics and maximum quantum eﬃciency of photosystem II (Fv/Fm) were decreased by sunlight­grown seedlings. Fv/Fm was induced by WBR and BR treatments, correlated with maximum yield of primary photochemistry (jP0). Quantum eﬃciencies (jP0, jE0 and y0) and performance index of absorption energy ﬂux (PIABS) were increased in BR­exposed transplants. In pot stage, LED-­treated plants exhibited better results in morphological features with earlier marketable ﬂowering stage especially under WBR, which can compensate costs of production in marketing stage.

title: Schaller and Matthiessen Journey Through the Himalayas: Two Contemporary Nature Writers Synthesize Science and Spirituality
Creators: name: Turner, Audrie Jane
Publisher: name: Utah State University
Year: 1996

description: Long before Charles Darwin's time, members of Western civilization viewed the sciences and spirituality as antithetical approaches to life. In the last 150 years, the argument for superiority of one over the other has continued, and Darwin's theories merely intensified the debate. However, American nature writing has evolved in a way that often synthesizes science and spirituality. This thesis will discuss this synthesis, and how two contemporary nature writers have dealt with the combination of science and spirituality in the natural and literary world. The merging of these two seemingly opposed subjects may be one of the most instructive and important approaches to the earth's environment and the future of humankind.
The Effect of Dwarf Galaxies on the Tidal Tails of Globular Clusters

description: The tidal tails of globular clusters have been shown to be sensitive to the external tidal field. We investigate how Galactic globular clusters with observed tails are affected by satellite dwarf galaxies by simulating tails in galaxy models with and without dwarf galaxies. The simulations indicate that tidal tails can be subdivided into into three categories based on how they are affected by dwarf galaxies: 1) dwarf galaxies perturb the progenitor cluster's orbit (NGC 4590, Pal 1, Pal 5), 2) dwarf galaxies perturb the progenitor cluster's orbit and individual tail stars (NGC 362, NGC 1851, NGC 4147, NGC 5466, NGC 7492, Pal 14, Pal 15), and 3) dwarf galaxies negligibly affect tidal tails (NGC 288, NGC 5139, NGC 5904, Eridanus). Perturbations to a cluster's orbit occur when dwarf galaxies pass within its orbit, altering the size and shape of the orbital and tail path. Direct interactions between one or more dwarf galaxies and tail stars lead to kinks and spurs, however we find that features are more difficult to observe in projection. We further find that the tails of Pal 5 are shorter in the galaxy model with dwarf galaxies as it is closer to apocentre, which results in the tails being compressed. Additional simulations reveal that differences between tidal tails in the two galaxy models are primarily due to the Large Magellanic Cloud. Understanding how dwarf galaxies affect tidal tails allows for tails to be used to map the distribution of matter in dwarf galaxies and the Milky Way.

Publisher: name: Utah State University
Year: 1996

description: During Winter and Spring Quarters 1995, I had the opportunity to become a tutor for Utah State University's Human Learning Clinic under the direction of Dr. Lani VanDusen, I chose to become involved in this endeavor to fulfill an Honors Independent study requirement for my "senior honor's experience". In doing so, l spent Winter Quarter preparing for the actual tutoring by familiarizing myself with the various intervention strategies adhered to by the clinic and becoming comfortable with the administration of the activities involved in each method. Prior to the beginning of Spring Quarter, I was assigned my own personal client: a fourteen-year-old male with behavioral and learning difficulties. I held ten weekly sessions with my client, each approximately ninety minutes long. The techiniques used in these sessions were very personalized, and I presented various intervention activities which I tailored to the needs of my client. I generally adhered to the pre-planned activity outline established by the clinic, but because my client was a very visual learner, I presented each activity in a visual-oriented manner by supplementing the outlined intervention strategies with visual aids, handouts, and interactive hands-on activities. The incorporation of visual learning techniques became the main focus of my project. Specific examples of these strategies will be described in detail throughout the course of this paper.

description: Numerably contractible spaces play an important role in the theory of homotopy pushouts and pullbacks. The corresponding results imply that a number of well known weak homotopy equivalences are genuine ones if numerably contractible spaces are involved. In this paper we give a first systematic investigation of numerably contractible spaces. We list the elementary properties of the category of these spaces. We then study simplicial objects in this category. In particular, we show that the topological realization functor preserves fibration sequences if the base is path-connected and numerably contractible in each dimension. Consequently, the loop space functor commutes with realization up to homotopy. We give simple conditions which assure that free algebras over a topological operad are numerably contractible.

Stable growth inhibition of potted fig (Ficus carica L.) trees by soil sickness
Creators: name: Hosomi, Akihiro
Publisher: name: Advances in Horticultural Science
Year: 2020

description: The study was conducted to know a damage progress of soil sickness of ﬁg trees and eﬀect of initial planting conditions on it. Shoot growth of 10liter potted ‘Masui Dauphine’ ﬁgs was inhibited with sick soil from the 1st year of planting, and a stable dwarﬁsh growth was maintained form the 2nd to 9th years, with only a few trees dying. The sick soil aﬀected trees planted in 25-­liter pots in June worse than those planted in February, and trees with roots enclosed by non-­woven fabric worse than without it. However, these diﬀerences had faded by the 3rd year. The sick soil aﬀected trees in 60­-liter pots in the 1st year of planting worse in smaller rooted cuttings than in larger ones. However, in subsequent years, growth inhibition was not aﬀected by the rooted cutting size. These results suggest that the initial conditions, such as planting timing, physical barriers to rooting, and rooted cutting size, all aﬀect potted ﬁg tree growth in the early growing period, and inﬂuence the observed damage caused by sick soil. However in subsequent years, dwarﬁsh growth in sick soil may attain a stable level, which is maintained for many years with very low mortality.

He named movements after geological eras, referred to images as coming from 'the dark land,' invented visual symbols for his scores, and concocted numerological schemes. For many listeners these extra musical trappings provided an avenue into the music itself, allowing them to listen to it openly and with interest rather than with resistance and skepticism" (Burge, 1990, p. 212).

description: Fusion reactions of heavy ions are investigated by employing a simple stochastic semi-classical model which includes the coupling between relative motion and low frequency collective surface modes of colliding ions similarly to the quantal coupled-channels description. The quantal effect enters into the calculation through the initial zero-point fluctuations of the surface vibrations. Good agreement with the result of coupled-channels calculations as well as data is obtained for the fusion cross sections of nickel isotopes. The internal excitations in non-fusing events as well as the fusion time are investigated.

description: We use the publicly available subhalo catalogs from the Via Lactea simulation along with a Gpc-scale N-body simulation to understand the impact of inhomogeneous reionization on the satellite galaxy population of the Milky Way. The large-volume simulation is combined with a model for reionization that allows us to predict the distribution of reionization times for Milky Way mass halos. Motivated by this distribution, we identify candidate satellite galaxies in the simulation by requiring that any subhalo must grow above a specified mass threshold before it is reionized; after this time the photoionizing background will suppress both the formation of stars and the accretion of gas. We show that varying the reionization time over the range expected for Milky Way mass halos can change the number of satellite galaxies by roughly two orders of magnitude. This conclusion is in contradiction with a number of studies in the literature, and we conclude that this is a result of inconsistent application of the results of Gnedin (2000). We compare our satellite galaxies to observations using both abundance matching and stellar population synthesis methods to assign luminosities to our subhalos and account for observational completeness effects. Additionally, if we assume that the mass threshold is set by the virial temperature Tvir = 8e3K we find that our model accurately matches the vmax distribution, radial distribution, and luminosity function of observed Milky Way satellites for a reionization time zreion = 9.6^{1.0}_{-2.1}, assuming that the Via Lacteasubhalo distribution is representative of the Milky Way. This results in the presence of 119^{+202}_{-50} satellite galaxies.

title: No Evidence of Linkage Between 35 Genetic Markers and the Spider Lamb Syndrome Gene in Sheep
Creators: name: South, Sarah Thornell
Publisher: name: Utah State University
Year: 1996

description: Spider Lamb Syndrome (SLS) is a semi-lethal congenital disorder affecting the Suffolk and Hampshire sheep breeds. The clinical manifestations of the syndrome include severe skeletal and muscular abnormalities with long, fine-boned legs, curvature of the spine and nasal septum, minimal muscling and severe muscle atrophy. The affected animals have a difficult time walking and most lambs do not survive past the first six months of life. A single autosomal recessive gene causes the disorder. Researchers believe the SLS gene arose as a single source mutation in a popular Suffolk blood line in the 1970s. Heterozygous carriers of the SLS gene appear normal in phenotype and currently can only be identified through progeny testing. If researchers could identify a genetic marker that cosegregates with the SLS locus, this marker could be used for low-cost carrier screening. In this study, we tested 35 bovine and ovine dinucleotide microsatellite markers as possible markers for the Spider Lamb Syndrome gene. No strong evidence for linkage between the tested microsatellite markers and the SLS gene was found.

description: We first apply the transformation of mixing azimuthal with wrapped coordinate to the 11D M-theory with a stack N M5-branes to find the spacetime of a stack of N D4-branes with magnetic field in 10D IIA string theory, after the Kaluza-Klein reduction. In the near-horizon limit the background becomes the Melvin magnetic field deformed $AdS_6 \times S^4$. Although the solution represents the D-branes under the Melvin RR one-form we use a simple observation to see that it also describes the solution of D-branes under the Maxwell magnetic field. As the magnetic field we consider is the part of the background itself we have presented an alternative to previous literature, because our method does not require the assumption of negligible back reaction. Next, we use the found solution to investigate the meson property through D4/D8 system (Sakai-Sugimoto model) and compare it with those studied by other authors. Finally, we present a detailed analysis about the Wilson loop therein and results show that the external Maxwell magnetic field will enhance the quark-antiquark potential.

title: Gregory Natural Bridge & La Gorce Arch: Escalante River Landscapes and History
Creators: name: Farmer, Jared Randall
Publisher: name: Utah State University
Year: 1996

description: Among abundant natural splendor, the canyons of the lower Escalante River enclose immense arches and bridges. Secluded in a jungle of slickrock, these natural spans attracted minimal attention until mid-century. Not until 1940 was Gregory Natural Bridge officially-if not genuinely-discovered. The "discoverer " was Norman Nevills, one of the most prominent and most colorful early commercial river runners in the West. Like Glen Canyon, Nevills' staple run, much of the bygone wilderness of the lower Escalante River now lies beneath Lake Powell. Gregory Natural Bridge was submerged by the filling reservoir, easily the largest span lost that way. Its present invisibility belies its past record of human association-with not only Nevills, but also surveyors, ranchers, and sundry travelers.

description: The security of chaotic optical communication using time-frequency (TF) representation is analyzed in this paper. The mean scalogram ratio (MSR) of TF representation and peak sidelobe level of MSR are defined to detect message. Algorithm for message detection and extraction is presented in detail. Two typical message encryption schemes, chaos masking and chaos modulation, are analyzed. The results reveal that it is not secure to transmit message when the message frequency locates at low power on power spectrum portrait. The proposed method is very useful for estimating the security level of message masking in chaotic optical communication.

description: Infrared laser systems are vital for applications in spectroscopy, communications, and biomedical devices, where infrared nonlinear optical (NLO) crystals are required for broadband frequency down-conversion. Such crystals need to have high non-resonant NLO coefficients, a large bandgap, low absorption coefficient, phase-matchability among other competing demands, e.g., a larger bandgap leads to smaller NLO coefficients. Here, we report the successful growth of single crystals of $γ$-NaAsSe$_2$ that exhibit a giant second harmonic generation (SHG) susceptibility of d$_{11}$=590 pm V$^{-1}$ at 2$μ$m wavelength; this is ~ eighteen times larger than that of commercial AgGaSe$_2$ while retaining a similar bandgap of ~1.87eV, making it an outstanding candidate for quasi-phase-matched devices utilizing d$_{11}$. In addition, $γ$-NaAsSe$_2$ is both Type I and Type II phase-matchable, and has a transparency range up to 16$μ$m wavelength. Thus $γ$-NaAsSe2 is a promising bulk NLO crystal for infrared laser applications.

description: Hot pepper is an important crop in Rwanda but viral diseases and pests are major constraints to its production. Field experiments were conducted to evaluate the resistance of 18 hot pepper genotypes (4 commercials, 5 introduced and 9 local) to natural infection by viruses and aphid infestation, in two agro­ecological zones of Rwanda. Fourteen genotypes were further evaluated for resistance to Cucumber mosaic virus (CMV) under screenhouse conditions. Disease incidence and severity were recorded in all experiments while population of aphids was assessed in the ﬁeld. Diseased leaf samples from each genotype in the ﬁeld were analysed using polymerase chain reaction to detect the presence of viruses, while samples from the screenhouse were analysed using serological assay. Results showed signiﬁcant (p<0.05) diﬀerences in disease incidence and severity among genotypes. Three genotypes namely PBC 462, 00767PPR and 0802PPR were rated as resistant to viral diseases while genotype HP 0117, PP9852­170 and PP9950­5197 were moderately resistant. All commercial and most of the local genotypes were susceptible compared to the introduced lines. There was no diﬀerence in genotype infestation by the aphids. The genotypes that are resistant to viruses are recommended for use by growers and in breeding programs.

Composition and fate of short-period super-Earths: The case of CoRoT-7b

description: The discovery of CoRoT-7b, a planet of radius 1.68 +/- 0.09 R_E, mass 4.8 +/- 0.8 M_E and orbital period of 0.854 days demonstrates that small planets can orbit extremely close to their star. We use knowledge of hot Jupiters, mass loss estimates and models for the interior structure and evolution of planets to understand its composition, structure and evolution. The inferred mass and radius of CoRoT-7b are consistent with a rocky planet that would be depleted in iron relative to Earth. However, a one sigma increase in mass (5.6 M_E) and decrease in size (1.59 R_E) are compatible with an Earth-like composition (33% iron, 67% silicates). Alternatively, it is possible that CoRoT-7b contains a significant amount of volatiles. An equally good fit to the data is found for a vapor envelope equal to 3% (and up to 10%) by mass above an Earth-like nucleus. Because of its intense irradiation and small size, the planet cannot possess an envelope of H and He of more than 1/10,000 of its total mass. We show that the mass loss is significant (~ 10^11 g/s) and independent of planetary composition. This is because the hydrodynamical escape rate is independent of the atmosphere's mean molecular mass, and owing to the intense irradiation, even a bare rocky planet would possess an equilibrium vapor atmosphere thick enough to capture stellar UV photons. This escape rate rules out the possibility of a H-He envelope as it would escape in only ~1 Ma. A water vapor atmosphere would escape in ~ 1 Ga, and thus it is a plausible scenario. The origin of CoRoT-7b cannot be inferred from present observations: It may have formed rocky; or be the remnant of a Uranus-like ice giant, or a gas giant with a small core that was stripped of its gaseous envelope.
description: This is a revised version of the paper submitted to astroph in July 17th 2009. It has been modified to include the measurement for CoRoT-7b's mass which was not determined until after the first version of this paper. 12 pages, 10 figures, accepted in A&A

description: We present the results of a search for occultation events by objects at distances between 100 and 1000 AU in lightcurves from the Taiwanese-American Occultation Survey (TAOS). We searched for consecutive, shallow flux reductions in the stellar lightcurves obtained by our survey between 7 February 2005 and 31 December 2006 with a total of $\sim4.5\times10^{9}$ three-telescope simultaneous photometric measurements. No events were detected, allowing us to set upper limits on the number density as a function of size and distance of objects in Sedna-like orbits, using simple models.

The evolution of massive clumps in star forming regions
Creators: name: Giannetti, Andrea <1986>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: FIS/05 Astronomia e astrofisica

description: In this thesis two related arguments are investigated:
- The first stages of the process of massive star formation, investigating the physical conditions and -properties of massive clumps in different evolutionary stages, and their CO depletion; 
- The influence that high-mass stars have on the nearby material and on the activity of star formation.

I characterise the gas and dust temperature, mass and density of a sample of massive clumps, and analyse the variation of these properties from quiescent clumps, without any sign of active star formation, to clumps likely hosting a zero-age main sequence star. I briefly discuss CO depletion and recent observations of several molecular species, tracers of Hot Cores and/or shocked gas, of a subsample of these clumps. 
The issue of CO depletion is addressed in more detail in a larger sample consisting of the brightest sources in the ATLASGAL survey: using a radiative tranfer code I investigate how the depletion changes from dark clouds to more evolved objects, and compare its evolution to what happens in the low-mass regime. 
Finally, I derive the physical properties of the molecular gas in the photon-dominated region adjacent to the HII region G353.2+0.9 in the vicinity of Pismis 24, a young, massive cluster, containing some of the most massive and hottest stars known in our Galaxy. I derive the IMF of the cluster and study the star formation activity in its surroundings. 

Much of the data analysis is done with a Bayesian approach. Therefore, a separate chapter is dedicated to the concepts of Bayesian statistics.
Exact potential-density pairs for flattened dark haloes
Creators: name: Baes, Maarten
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Cosmological simulations suggest that dark matter haloes are not spherical, but typically moderately to strongly triaxial systems. We investigate methods to convert spherical potential-density pairs into axisymmetric ones, in which the basic characteristics of the density profile (such as the slope at small and large radii) are retained. We achieve this goal by replacing the spherical radius r by an oblate radius m in the expression of the gravitational potential. We extend and formalize the approach pioneered by Miyamoto & Nagai (1975) to be applicable to arbitrary potential-density pairs. Unfortunately, an asymptotic study demonstrates that, at large radii, such models always show a R^(-3) disc superposed on a smooth roughly spherical density distribution. As a result, this recipe cannot be used to construct simple flattened potential-density pairs for dynamical systems such as dark matter haloes. Therefore we apply a modification of our original recipe that cures the problem of the discy behaviour. An asymptotic analysis now shows that the density distribution has the desired asymptotic behaviour at large radii (if the density falls less rapidly than r^(-4)). We also show that the flattening procedure does not alter the shape of the density distribution at small radii: while the inner density contours are flattened, the slope of the density profile is unaltered. We apply this recipe to construct a set of flattened dark matter haloes based on the realistic spherical halo models by Dehnen & McLaughlin (2005). This example illustrates that the method works fine for modest flattening values, whereas stronger flattening values lead to peanut-shaped density distributions.
