Ly alpha emission galaxies in the FORS Deep Field
… Abdeckungsgrad. Alle Spektren enthalten die Lyman-alpha-Linie, welche von reiner Absorption bis zu starker Emission (Emissions-EW = -20 bis 270 Å) reicht. Die meisten Emissionslinien sind asymmetrisch, drei Galaxien besitzen ein Lyman-alpha-Profil mit zwei Emissionskomponenten. Die …

LAYER BY LAYER NANOASSEMBLY OF COPPER INDIUM GALLIUM SELENIUM (CIGS) NANOPARTICLES FOR SOLAR CELL APPLICATION
… further used in layer by layer (LbL) nanoassembly of CIGS films. CIGS nanoparticles were synthesized through the colloidal precipitation in an organic solvent. The peak and average sizes of the synthesized particles were measured to be 68 nm and 75 nm in chloroform, and 30 nm and 115 nm in …

The Nature of Emission-Line Galaxies in Hierarchical Cosmologies
… In particular, we focus on the properties of Ly-alpha and H-alpha emitters, due to their many cosmological applications being considered for current and future observational studies. By combining a semianalytical model with a large N-body simulation we predict the clustering of Ly-alpha …

Effects of TGF-β Inhibitor on Chemoresistance in Ovarian Cancer Models
… nature of the tumours. Despite an initially favourable treatment response, patients with HGSC often develop resistance to the first-line platinum-based chemotherapies. In addition, the few currently available second line treatments, such as doxorubicin (Dox), often fail to elicit a …

Emission Line Galaxies from CADIS : High Redshift Lyman-Alpha Galaxies and Metal Poor Galaxies at Medium Redshift
… thesis, metal poor galaxies at 0.4<z<0.7 and Ly-alpha galaxies at z>4.7 have been searched for and investigated in a sample of 600 faint emission line galaxies from four fields of the Calar Alto Deep Imaging Survey (CADIS). Employing an imaging Fabry-Perot interferometer, CADIS detects …

Cosmological hydrodynamic simulations of the Lyman-alpha forest
… simulations of the formation and evolution of Ly$\alpha$ forest absorbers were performed in three CDM-like cosmological models: the standard CDM model (SCDM), the flat CDM model with a nonzero cosmological constant ($\Lambda$CDM) and the open CDM model (OCDM). Synthetic spectra along random …

Thermal and Kinetic Analyses of the Pyrolysis of a Northern Great Plains Lignite
<p>The pyrolysis of Indian Head lignitic coal in argon, carbon monoxide and hydrogen was studied to obtain a kinetic model of the process and to determine heat effects . A Du Pont 910 differential scanning calorimeter and a Du Pont 951 therm ogravim etric analyzer were utilized to measure heat …

Developing a co-culture model of ovarian cancer to identify immunotherapies that can overcome TGF-β-induced immunosuppression
… ovarian cancer (HGSC) being the most commonly diagnosed and aggressive subtype. Although HGSC initially responds well to debulking surgery and platinum-based chemotherapy, approximately 80% of patients experience recurrence and subsequent treatment resistance. Immunotherapies have shown …

Functional and Transcriptional Heterogeneity of the Human Haematopoietic Stem Cell Pool at Steady-State and Under Inflammation
Blood production is coordinated by a functionally heterogeneous pool of multipotent haematopoietic stem cells (HSCs), downstream of which lineage-restricted progenitors are generated. The advent of single cell technologies has changed our view of the haematopoiesis to a dynamic continuum. …

Experimental Studies of Neutral Particle Effects on Edge Transport Barriers in Tokamaks Using the Lyman-alpha Measurement Apparatus
… particle source, a one-dimensional, absolutely calibrated pinhole camera system was installed on the DIII-D tokamak to measure edge Lyman-alpha (Ly-𝛼) emission. Ly-𝛼 emission from hydrogenic isotopes can be used to infer hydrogenic neutral density and ionization rate profiles. To provide a …

Quasar continuum fitting and silicon absorption on the low redshift intergalactic medium
We present results on the evolution of Ly[alpha] absorption at low redshift, and the first systematic search for Si II absorption systems in the low redshift IGM. Our sample consists of 832 Ly[alpha] absorbers from 328 spectra of 204 QSOs taken from the Hubble Space Telescope archive. We develop a …

Degree Theory and Nonlinear Boundary Value Problems at Resonance
… non-linear differential operator ${\cal L}y$ = Ly + $\eta y\sp3$, where $\eta$ = $\pm$1 and L, the linear part of ${\cal L}$, is of the form Ly = $y\sp{\prime\prime}$ + $p(x)y\sp\prime$ + q(x)y. Assume p(x) and q(x) are integrable on (a,b). We study the existence and uniqueness of solutions of …

The ATP synthase from spinach chloroplasts (Spinacea oleracea) : improved isolation and purification of the enzyme and conformational changes observed with fluorescent labels
… CF0F1, is an integral membrane enzyme, which catalyses the synthesis of ATP from ADP and Phosphate. The reaction is driven energetically by proton-transport across the enzyme. The activity of the enzyme is regulated through a transmembrane pH-difference and a redox process, in which a disulfide …
