Si « l’État intégral » zaïrois ambitionne d’étouffer toute contestation, crucial l’industrie minière pour l’économie permet à ses d’être partiellement...

1. The cycle groups C8. An algebraic variety F i n w-dimensional complex projective space P ( n ) is obtained by equating to zero a finite number of forms Fi(x0, • • • , xn)f • • • , Fm(xo, • • • , xn) with complex coefficients ; F is assumed to be nonempty. If F i s irreducible, that is, if V is not the union of a finite number of proper subvarieties, it is possible to associate with V in seve...

This paper deals with an investigation of different control strategies for a series hybrid electric vehicle (SHEV). Another discussed issue is the application of a free-piston generator. By replacing a conventional combustion engine with a free-piston generator it is possible to increase the total efficiency of the system. The object of investigation is a 12-ton truck, mainly used in urban area...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

In order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, in 2013-14. The treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). The experimental design was a factorial experiment based on randomized ...

The aim of this study is to assess the effects of hypervolemic infusion with different solutions on microcirculation perfusion during laparoscopic colorectal surgery.Thirty-six patients were randomly divided into Ringer lactate solution [RL] group, succinylated gelatin injection [Gel] group, and hypertonic saline hydroxyethyl starch 40 injection [HS] group. Hypervolemic infusion was performed d...
