The QSO lifetime tQ is one of the most fundamental quantities for understanding black hole and QSO evolution, yet it remains uncertain by several orders of magnitude. If tQ is long, then only a small fraction of galaxies went through a luminous QSO phase. In contrast, a short lifetime would require most galaxies today to have undergone a QSO phase in their youth. The current best estimates or c...

OBJECTIVE The discovery and development of natural products with potent antioxidant properties has been one of the most interesting and promising approaches in the search for treatment of CNS injuries. The most significant consequence of the oxidative stress is thought to be the DNA modifications, which can become permanent via the formation of mutations and other types of genomic instability r...

While most surgeons are well aware of outcomes studies and quality assessment based on technical quality (TQ) measurements, there has been little attention given in the plastic surgery literature to the discussion of functional quality (FQ)-the process by which a health care service is delivered, as opposed to the actual procedure itself. Most patients judge the quality of their hospital experi...

We review properties of so-called special conformal Killing tensors on a Riemannian manifold (Q, g) and the way they give rise to a Poisson–Nijenhuis structure on the tangent bundle TQ. We then address the question of generalizing this concept to a Finsler space, where the metric tensor field comes from a regular Lagrangian function E, homogeneous of degree two in the fibre coordinates on TQ. I...

background: toxic effects of anti-cancer and other drugs on the normal tissues could be reduced by the herbal plants and their fractions. this study investigated the protective effect of thymoquinone (tq) as a fraction of nigella sativa on methotrexate (mtx)- induced germ cell apoptosis in male mice. materials and methods: in this experimental study, thirty male balb/c mice were divided randoml...

Objective: The neuroprotective effects of thymoquinone (TQ), the active compound Nigella sativa, have been reported in accordance with anti-inflammatory and antioxidant features this drug. It has suggested that cerebellum plays a considerable role neurodegenerative processes. In current study, possible TQ on structure composition tissues its total capacity were studied dose-dependently. Materia...

apart from the linguistic ability in translation which has constantly been the focus of scholars in the past decades, many recent arguments and research on translation quality point to the indispensable effect of mental and cognitive aspects of translator on his translation performance. in this paper we sought to implement this psychological approach and to investigate the probable relationship...

For a field k of characteristic zero, we study the field of Noetherian power series, k〈〈tQ〉〉, which consists of maps z : Q → k whose supports are Noetherian (i.e., reverse well-ordered) subsets of Q. There is a canonical valuation LE : k〈〈tQ〉〉 → Q ∪ {−∞} that sends a nonzero series to the maximum element of its support. Given a nonzero polynomial f(x, y) ∈ k[x, y] and a series z ∈ k〈〈tQ〉〉 that ...

Round Robin (RR) scheduling algorithm is a preemptive scheduling algorithm. It is designed especially for time sharing Operating System (OS). In RR scheduling algorithm the CPU switches between the processes when the static Time Quantum (TQ) expires. RR scheduling algorithm is considered as the most widely used scheduling algorithm in research because the TQ is equally shared among the processe...

This study explored the relationships among a behavioral and verbal measure of delay of gratification, Porteus Maze Test measures of planning ability and foresight (TQ) and impulse control (Q), and ratings of adjustment in a school for delinquent adolescent males. Both measures of delay of gratification were significantly related to the Porteus measures and the adjustment ratings. Delay of grat...
