An extract of Ruta graveolens was found to be cytotoxic to Dalton's lymphoma ascites (DLA), Ehrlich ascites carcinoma (EAC) and L929 cells in culture (IC100=16 mg/ml) and also to increase the lifespan of tumour bearing animals. The extract further decreased solid tumours developing from DLA and EAC cells when given simultaneously with elongation of the lifespan of tumour-bearing animals. A home...

A new method of generating realistic three dimensional simulated breast 12 lesions known as diffusion limited aggregation (DLA) is presented, and compared 13 with the random walk (RW) method. Both methods of lesion simulation utilize a 14 physics-based method for inserting these simulated lesions into 2D clinical mammogram 15 images that takes into account the polychromatic X-ray spectrum, loca...

The method of iterated conformal maps for the study of diffusion limited aggregates (DLA) is generalized to the study of Laplacian growth patterns and related processes. We emphasize the fundamental difference between these processes: DLA is grown serially with constant size particles, while Laplacian patterns are grown by advancing each boundary point in parallel, proportional to the gradient ...

Some results from an imaging program to identify low-redshift (0.09 < z < 1.63) damped Lyα (DLA) galaxies are presented. The standard paradigm that was widely accepted a decade ago, that DLA galaxies are the progenitors of luminous disk galaxies, is now being seriously challenged. The indisputable conclusion from imaging studies at low redshift is that the morphological types of DLA galaxies ar...

WSTĘP Od czasu pierwszego zastosowania u człowieka automatycznego kardiowertera-defibrylatora (ICD) w 1980 r. nastąpił znaczący postęp technologiczny. Urządzenia z elektrodami wszczepialnymi nasierdziowo przez torakotomię zostały zastąpione układami całkowicie przezżylnymi. Kolejne modyfikacje pozwoliły na zastosowanie sterowania i stymulacji dwujamowej, a także w późniejszym okresie — terapii ...

Dogs exhibit a range of immune-mediated conditions including a lymphocytic thyroiditis which has many similarities to Hashimoto's thyroiditis in man. We have recently reported an association in Doberman Pinschers between canine hypothyroidism and a rare DLA class II haplotype that contains the DLA-DQA1*00101 allele. We now report a further series of 173 hypothyroid dogs in a range of breeds whe...

We have searched for molecular hydrogen in damped Lyman-α (DLA) and subDLA systems at high redshift (zabs > 1.8) using UVES at the VLT down to a detection limit of typically N(H2) = 2×10 14 cm. Out of the 33 systems in our sample, 8 have firm and 2 have tentative detections of associated H2 absorption lines. Considering that 3 detections were already known from past searches, molecular hydrogen...

We explore the possibility of resolving an image of a damped Lyα (DLA) system in absorption against an extended, diffuse background X–ray source. Typical columns of neutral hydrogen in DLA systems are high enough to block out up to ∼ 30% of the soft X–ray flux at an observed photon energy of 0.5 keV, and we find that ∼ 1% of the area of extended X–ray sources at z & 1 have their 0.5 keV flux re...

We report the detection, both in line and continuum emission, of a galaxy responsible for a damped Lyα absorption (DLA) system at z = 3.15 projected 2.3 from QSO 2233+131. The star formation rate implied by both the Lyα and restframe far-UV continuum is ∼ 7 M⊙ yr . The galaxy also shows no sign of an active nucleus and has blue colors, both consistent with it being observed early in its star fo...

The aim of this paper is to provide a logical framework for reasoning about actions, agency, and powers of agents and coalitions in game-like multi-agent systems. First we define our basic Dynamic Logic of Agency DLA. Differently from other logics of individual and coalitional capability such as Alternating-time Temporal Logic ATL and Coalition Logic, in DLA cooperation modalities for expressin...
