Authors: Holušová Táňa , Lozano Miguel , Fernández-Canteli Alfonso , Komárková Tereza , Kocáb Dalibor , Seitl Stanislav 
Published: January 2016

Abstract
The modified compact tension test (MCT) might become in the future a stable test configuration for the evaluation of fracture-mechanics parameters or also for description of fatigue behavior of composites materials such as concrete. Core drilling is used for sampling of existing structures. These samples have cylindrical shape with the selected thickness to avoid the stress concentration. This contribution focuses on the evaluation of the fracture behavior during static and quasi static tests. Static tests are performed on standard specimen with diameter 150 mm and length 300 mm. The quasi-static tests are performed using two different gripping fixtures. The results for quasi-static tests are represented as L-COD diagrams (i.e. load vs. crack opening displacement) measured on the loading axis. The comparison of results and discussion of advantages and disadvantages are introduced.

Objective To assess grommet insertion practice in the first 5 years of life among children with an orofacial cleft in England. Design Analysis of national administrative data of hospital admissions. Setting National Health Service hospitals, England. Patients Patients born between 1997 and 2005 who underwent surgical cleft repair. Intervention Children receiving grommets before the age of 5 years. Outcome Measures The proportion of children receiving grommets before the age of 5 years, the timing of the first grommet insertion, and the proportion of children having repeat grommet insertions were examined according to cleft type, the absence or presence of additional anomalies, socioeconomic deprivation, and region of residence. Results The study included 8,269 children. Before the age of 5 years, 3,015 (36.5%) children received grommets. Of these, 33.2% received their first grommets at primary cleft repair and 33.3% underwent multiple grommet insertion procedures. The most common age for the first procedure was between 6 and 12 months. Children with a cleft affecting the palate were more likely to receive grommets than children with a cleft lip alone (45.5% versus 4.5%). Grommet insertion practice also varied according to year of birth, absence or presence of additional anomalies, socioeconomic deprivation, and region of residence. Conclusion Grommets practice in children with a cleft appears to vary according to their clinical characteristics. The differences in practice observed according to deprivation and region of residence need to be further explored.

Objective To demonstrate the feasibility of rapid maxillary expansion (RME) after alveolar bone grafting (ABG) in complete unilateral cleft lip, alveolus and palate (UCLP) without damage to the grafted area. Setting Hospital for Rehabilitation of Craniofacial Anomalies (HRAC), University of São Paulo, Department of Orthodontics. Patient A case report of a 10-year-old boy with a complete UCLP who was treated with RME after secondary ABG procedure. RME was performed 1.3 years after the bone grafting with rhBMP-2 in collagen membrane. Result Postexpansion cone-beam computed tomography (CBCT) axial and coronal sections demonstrated the opening of the midpalatal suture in the premaxilla without damages to the alveolar bone grafting region. Postretention CBCT images showed bone formation at the split midsuture of the premaxilla. Conclusion Rapid maxillary expansion performed after ABG with rH-BMP2 led to complete opening of the premaxillary midline suture without compromising the integrity of the grafted alveolar cleft.

Published: January 2016

Objective To compare facial growth characteristics in patients with cleft palate who have undergone pharyngeal flap with those who had palatal lengthening or pharyngoplasty and to control subjects who have not had surgery for velopharyngeal insufficiency (VPI). Design Matched retrospective cohort study. Setting Multidisciplinary cleft care center. Patients All patients with cleft palate who had undergone pharyngeal flap or pharyngoplasty/palatal lengthening for VPI were included. Patients with craniofacial syndromes or those who had undergone maxillary protraction were excluded. A control group did not undergo surgery for VPI. The three groups were matched based on cleft type and ages at VPI surgery and cephalogram. Main Outcome Measures Thirteen craniofacial measurements were evaluated on postoperative cephalograms using an analysis of variance with a Bonferroni adjustment for significant measures (α = 0.05). Results Seventy-two patients were included; mean ages at VPI surgery and postoperative cephalogram were 5 and 8 years, respectively. Twelve of thirteen craniofacial measures were not significantly different; notably, this included maxillary height and projection. Only gonial angle was found to differ significantly ( P = .018) in that pharyngoplasty and pharyngeal flap yielded a smaller angle compared with that in control subjects. Conclusion Facial growth, and in particular maxillary growth, was not altered as expected after pharyngeal flap surgery. Pharyngeal flap appears to be equivalent to pharyngoplasty and palatal lengthening in that no significant effects on early facial growth were detected after surgery for VPI in this cohort of children with cleft palate.

Numerical Evaluation Of Effective Thermal Properties For Materials With Variable Porosity
Authors: Staňák P. , Sládek J. , Sládek V. , Krahulec S. 
Published: January 2016

Abstract
In this paper a computational homogenization technique is applied to thermal analyses in porous materials. A volume fraction of pores on the microstructural level is the key factor that changes the macroscopic thermal properties. Thus, the distribution of thermal fields at the macroscopic level is analysed through the incorporation of the microstructural response on the representative volume element (RVE) assuming a uniform distribution of pores. For the numerical analysis the scaled boundary finite element method (SBFEM) is introduced to compute the thermal response of RVE. The SBFEM combines the main advantages of the finite element method (FEM) and the boundary element method (BEM). In this method, only the boundary is discretized with elements leading to the reduction of spatial dimension by one, similarly as in the BEM. It reduces computational efforts in the mesh generation and CPU time. The proposed method is used to study square RVE with a circular and elliptic pore under the thermal load. Dimensions of the pore are varied to obtain different volume fractions of matrix material. Numerical results for effective thermal conductivities obtained via SBFEM modelling show an excellent agreement with the finite element analysis using commercial software COMSOL Multiphysics.

Authors: Al-Swaidani A. , Aliyan S. , Adarnaly N. , Hanna B. , Dyab E. 
Published: January 2016

Abstract
In the study, three types of cement have been prepared; one CEM I type (the control sample) and two blended cements: CEM II/A-P and CEM II/B-P (EN 197-1), each of them with three replacement levels of volcanic scoria: (10 %, 15 %, 20 % wt.) and (25 %, 30 %, 35 % wt.), respectively. Strength development of mortars has been investigated at 2, 7, 28 and 90 days curing. Evaluation of chemical resistance of mortars containing scoria-based cements has been investigated through exposure to 5 % sulphate and 5 % sulphuric acid solutions in accordance with ASTM C1012 & ASTM 267, respectively. Drying shrinkage has been evaluated in accordance with ASTM C596. Test results showed that at early ages, the mortars containing CEM II/B-P binders had strengths much lower than that of the control mortar. However, at 90 days curing, the strengths were comparable to the control mortar. In addition, the increase of scoria significantly improved the sulphate resistance of mortars. Further, an increase in scoria addition improved the sulphuric acid resistance of mortar, especially at the early days of exposure. The results of drying shrinkage revealed that the CEM II/B-P mortar bars exhibited a greater contraction when compared to the control mortar, especially at early ages. However, drying shrinkage of mortars was not influenced much at longer times.

Published: January 2016

Abstract
An experiment was conducted in order to investigate the effects of exogenous polyamines (PAs) on the development of mycorrhizae in roots, nutrient uptake and vegetative and reproductive growth of Freesia hybrida ‘Golden Wave’. Corms of freesia were inoculated with Rhizophagus intraradices at sowing time and treated once a week by one of three PAs, putrescine (Put), spermidine or spermine, in concentrations of 0.05 and 0.1 mM each as foliar application or soil drench. Application of PAs, especially as soil drench, increased mycorrhizal colonization as well as the growth and development of inoculated plants. Among the three PAs, Put in 0.1 mM concentration was the most effective in increasing colonization, enhancing floral stem length and diameter, floral spike length, floret number on main and lateral spikes and increasing corm and cormlet weight, corm diameter and cormlet number. Sole application of arbuscular mycorrhizal fungi had no significant effect on the flowering time but soil drench with 0.1 mM Put accelerated flowering by about 17 days. Application of PAs elevated leaves N, P, K, Mg, Fe and Zn and corms’ P, K, Ca, Fe and Zn concentration of inoculated plants. Our results suggest that soil drench application of PAs, especially Put, positively influenced mycorrhizal inoculation and nutrient uptake, which leads to improving growth, flower and corm production and quality of mycorrhizal plants of freesia.

Authors: Sokolov Rosen S. , Atanassova Bistra Y. , Iakimova Elena T. 
Published: January 2016

Abstract
In this study, the effects of compounds providing Fe in chelated (NaFeEDTA and Fe(III)AC) and non-chelated (FeSO4·7H2O) forms as components of culture media, on in vitro shoot multiplication and rooting of Magnolia soulangeana ‘Alexandrina’, Magnolia grandiflora and Prunus cerasifera ‘Nigra’ were comparatively evaluated. Each of the tested chemicals was used as a single Fe source in the basal salt medium. In the stages of shoot multiplication and rooting plant response was scored by biometrical indices (number of shoots, leaves and roots, shoot and root length, percent of rooted plants and root hairs). The occurrence of physiological disorders was estimated by visual observations. In presence of FeSO4, symptoms of chlorosis, hyperhy-dricity, early senescence and specific morphology of roots, suggesting Fe deficiency, were observed. These deteriorations were entirely prevented at the application of Fe chelates of which, in this experimental systems, Fe(III)AC was tested for the first time. The addition of Fe(III)AC positively affected the plant quality to extent comparable to that of NaFeEDTA. The obtained data suggest that both applied Fe chelates are more appropriate than non-chelated Fe form and can be alternatively used in the optimization of nutrient media for micropropagation of Magnolia and Prunus cerasifera genotypes.
