cash flow forecasting is an indispensable tool for construction companies, and is essential for the survivalof any contractor at all stages of the work. the time available for a detailed pre-tender cash flow forecast is oftenlimited. therefore, contractors require simpler and quicker techniques which would enable them to forecast cash flowwith reasonable accuracy. forecasting s-curves in constr...

UNLABELLED According to the IBGE, Brazil had 21 million elderly persons in 2008. OBJECTIVE To study the effects of speech therapy - fitting of hearing aids - on the quality of life of elderly persons and restriction of participation according to sex and age. MATERIAL AND METHOD 50 elderly subjects, 23 females and 27 males, were allocated to Group 1 and Group 2, and were assessed with questi...

Let G be an arbitrary group. We show that if the Fitting subgroup of G is nilpotent then it is definable. We show also that the class of groups whose Fitting subgroup is nilpotent of class at most n is elementary. We give an example of a group (arbitrary saturated) whose Fitting subgroup is definable but not nilpotent. Similar results for the soluble radical are given.

The aim of this study was to determine the rehabilitation outcome of lower limb amputee patients after clinical rehabilitation. Altogether 183 amputee patients admitted for clinical rehabilitation in the years 1987-1991 were reviewed by retrospective analysis of medical record data. Three groups of amputee patients were identified by reason for amputation. The vascular group: (N = 132), mean ag...

PURPOSE To determine the effect of the base curve radius (BCR) of therapeutic soft contact lens (T-lens) on epithelial healing after laser-assisted subepithelial keratectomy (LASEK). METHODS Ninety-two eyes in 47 patients with myopia were prospectively evaluated after LASEK. All the patients wore T-lenses with the BCR (R1) randomly chosen after LASEK. The T-lenses were removed after complete ...

The Fitting subgroup of a type-definable group in a simple theory is relatively definable and nilpotent. Moreover, the Fitting subgroup of a supersimple hyperdefinable group has a normal hyperdefinable nilpotent subgroup of bounded index, and is itself of bounded index in a hyperdefinable subgroup.

introduction: this in vitro study investigates the marginal and internal fit of indirect class ii composite restorations. two different processes for chair-side restorations were compared. in group a, the restorations were fabricated using cad/cam technology (cerec, sirona, germany, bernsheim) and in group b they were made by hand (grandioso inlay system, voco gmbh, germany, cuxhaven). methods:...
