In this paper, we consider three different search strategies for a cut-free sequent system formalizing orthologic, and estimate the respective search spaces. Applying backward search, there are classes of formulae for which both the minimal proof length and the search space are exponential. In a combined forward and backward approach, all proofs are polynomial, but the potential search space re...

pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...

In design of a parallel resonant induction heating system, choosing a proper capacitancefor the resonant circuit is quite important. The capacitance affects the resonant frequency, outputpower, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent seriesresistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of resonancecapacitor i...

background: unripe cervix is one of the most causes of failure of labor induction. there are different methods for labor induction, which may differ depending on its duration. this study was performed to compare the effectiveness of vaginal misoprostol intravenous and oxytocin for induction of labor on hospitalized patients. methods: in a randomized clinical trail 110 pregnant women with bishop...

Let T = τ + 1/C, where τ is the fixed propagation delay. Divide the time into intervals of T , starting from time t = 0. We number the intervals, starting from interval 0. Let the interval n be [nT, (n + 1)T ), for n = 0, 1, 2, .... Let us further divide each interval into identical time slots, each of which is equal to the transmission time of a fixed-size packet, 1/C. We assume CT is an integ...

The period enforcer algorithm for self-suspending real-time tasks is a technique for suppressing the “backto-back” scheduling penalty associated with deferred execution. Originally proposed in 1991, the algorithm has attracted renewed interest in recent years. This note revisits the algorithm in the light of recent developments in the analysis of self-suspending tasks, carefully re-examines and...

The thesis concerns the (class) structure No of Conway’s surreal numbers. The main concern is the behaviour on No of some of the classical functions of real analysis, and a definition of integral for such functions. In the main texts on No, most definitions and proofs are done by transfinite recursion and induction on the complexity of elements. In the thesis I consider a general scheme of defi...

A novel strategy to increase protein expression yield is unintended induction of expression in complex media, called auto-induction. This method can be used to express proteins under control of the lac promoter without any need to monitor bacterial growth pattern, and addition of specific expression inducers such as Isopropyl β-D-1-thiogalactopyranoside (IPTG) at proper time. In the present stu...
