Abstract: The objective of this work was to determine the genetic parameters and efficiency different selection indices for biofortified red leaf lettuce (Lactuca sativa var. crispa) lines with agronomic nutritional potential. experiment carried out in a randomized complete block design three replicates 31 crisp-textured red-tinted genotypes: Belíssima cultivar, low carotenoid content rich anth...

Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...

Reproductive timing is a critical life-history event that could influence the (co)variation of traits developing later in ontogeny by regulating exposure to seasonally variable factors. In a field experiment with Arabidopsis thaliana, we explore whether allelic variation at a flowering-time gene of major effect (FRIGIDA) affects (co)variation of floral traits by regulating exposure to photoperi...

Onion is an herbaceous biennial monocot cultivated as annual. In most research the greater seed yield in onion cultivars used to be due higher range of stalks per plant and a wider umbel diameter which had been influenced through utility Nitrogen Phosphorus fertilizers. The wide variety flower opening on every day was by using hours sunshine attention phosphorous nitrogen. remedies tended decre...

As networks grow in size and complexity, network management has become an increasingly challenging task. We argue that “bolting on” network-management functions to the existing architecture is the wrong approach. Instead, networks should be designed with management in mind from the beginning. We focus on two important aspects of network management: tomography and optimization. We present princi...

This paper presents an approach to Cartesian controlled heavy machines. The system under investigation is a drill rig equipped with two drilling booms each actuated by eight hydraulic drives. To improve accuracy and efficiency in both possible operation modes, drilling and bolting, a Cartesian control system has been implemented, which takes advantage of using different subsets of the redundant...

In view of the deformation and instability law hard roof without side filling retaining roadway, based on systematic construction analysis force bearing model roadway structure, this article proposes control mechanical calculation method retaining, which takes anchor beam key block above to form cantilever together, with solid coal as foundation support. The research practice show that under co...

Coal auger mining is a promising technology used for excavating thin coal seams. The efficiency of largely related to the stability mine roadways in influence zone coal-face. Roof bolting systems are such conditions. An adequate choice roof parameters only possible if one understands features stratification rocks and stages deformation array mining. Modern monitoring methods condition based on ...
