In an experiment described by Fishman et al. [1994], high energy photons of atmospheric origin were detected by the Burst and Transient Source Experiment (BATSE) detectors, located on the Compton Gamma Ray Observatory (CGRO). In this paper we assess the possibility that the bursts may be bremsstrahlung produced by relativistic (> 1 MeV) runaway electron beams accelerated in an avalanche process...

Many orthodontic treatment modalities will yield a better result in less time if properly correlated with the unique facial growth patterns of the patients. The pubertal growth spurt depends on gender and varies in relationship to the chronologic age. General skeletal maturity usually is used as an indicator to predict timing of mandibular growth velocity peak. Hand-wrist radiographic evaluatio...

The aim of this study was to investigate the relationships between stages calcification various teeth and skeletal maturity among Korean subjects. samples were derived from hand-wrist, panoramic radiographs, lateral cephalograms 743 subjects (359 males 384 females) with ages ranging 6 14 years. Calcification seven permanent mandibular on left side rated according system Demirjian. To evaluate s...

Abstract This article investigates the activities of Kurdish women aimed at protecting and revitalising language, which include collecting publishing folklore, translating into Kurdish, writing literature in Kurdish. Throughout 20th century, countries like Turkey, Syria, Iran, Iraq, varying degrees, imposed restrictions on use Our primary focus is Turkey because this country has been most repre...

We characterize the optimal long-term financial contract in a setting in which a risk-neutral agent with limited capital seeks external financing for a project which pays stochastic cash flows over many periods. These cash flows are unobservable and unverifiable by outside investors. The agent can be induced to pay investors via the threat of the loss of control of the project. After solving fo...

As a result of the work of Levvy et al. (1948), it is no longer necessary to postulate a synthetic role for fl-glucuronidase in the body (Fishman, 1940) in order to explain the changes in the activity of the enzyme which can be produced in various organs. The view that ,B-glucuronidase is not involved in glucuronide synthesis (Levvy, 1948) receives support from the failure of saccharic acid to ...

This paper develops a unified framework to analyze the dynamics of firm investment in countries with poor legal enforcement. The firm’s technology edge over the government generates endogenous property rights. Industry variation in the technology gap predicts a sectoral pecking-order of expropriations. Long-run investment distortions may be Pareto superior relative to persistent investment at t...
