Seifert Fibre Groups (SF-Gps) have been introduced and their first derived groups have been worked out in an earlier paper by the author [2,3]. Now we aim to prove that they are residually soluble and residually finite.

Cultivation of strawberries in greenhouses and polytunnels is increasing, new sustainable growing media are needed to replace peat coconut coir. This study investigated the effect wood fiber compost as on hydroponically cultivated strawberries. Two experiments were conducted, where everbearing cultivar ‘Murano’ was grown mixtures (Experiment 1) seasonal flowering ‘Malling Centenary’ 2). Additio...

Ground vibrations can be caused by various sources such as traffic, construction activities, and industrial machinery. These propagate through the ground into adjacent structures or environment. Predicting controlling are essential in fields, transportation, construction, activities. Regulations guidelines have been developed many countries to manage impact of on people structures. Open In-fill...

A field experiment was conducted to evaluate the yield and chemical composition of triticalegrain in different crop rotation and tillage systems. The first experimental factor was thecropping system – a) crop rotation and b) monoculture and the second factor was the tillagesystem – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yieldwas found to be 15.4% high...

The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...

The effect of fibre bundling on the effective transverse properties of unidirectional fibre composites has been investigated by way of finite element method and micromechanics models of fibre bundles. Based on the micromechanical model of single-fibre composites, plane strain models for composites reinforced by fibre bundles are presented. The effective elasto-plastic stress /strain behaviour w...
