Una escudilla con decoración figurativa procedente de la Judería de Teruel
Authors: Hernández Pardos Antonio
Published: January 2016

Dentro del conjunto material hallado recientemente bajo la plaza de la Judería de Teruel, sobresale una pieza cerámica, una escudilla de elaboración local fechada entre finales del siglo XIII e inicios del XIV. Su singularidad procede de su decoración, en la que se representa a dos personajes que creemos judíos, con paralelos claros en las iconografías judaica y cristiana hispanas de la época. Se trata de un hallazgo de enorme interés, por su carácter único dentro del corpus iconográfico y repertorio cerámico medievales. En todo caso, constituye un magnífico exponente de la pujanza de la aljama turolense durante la Baja Edad Media.
Nosotros, vosotros, ellos: relatos de viajeros judíos del siglo XV a la luz del concepto de alteridad
Authors: Cano Pérez María José , García Arévalo Tania María
Published: January 2016

La literatura de viajes podría considerarse el nexo de multitud de tipos de textos dentro del genero de la narrativa. Sin embargo, los datos que ofrece desde el punto de vista histórico, geográfico o sociológico, entre otros, hacen de ella un registro del que subyacen además las experiencias propias de los viajeros en sus travesías. De este modo, resultan especialmente destacadas en estudios de identidad en los que observar la alteridad que muestran los autores en sus escritos en los que describen, de manera constante, su percepción de los lugares que visitan pero también las diferentes comunidades, judías y no judías, con las que se encuentran. En estas paginas se ofrece un estudio acerca de las impresiones de autores medievales del siglo XV en sus viajes.

Cellular Automata-Based PSO Algorithm for Aligning Multiple Molecular Sequences
Authors: Jayakumar Jayapriya , Arock Michael
Published: January 2016

In Bioinformatics, sequence analysis is the basic important concept that provides information for structural and functional analysis. Multiple Sequence Alignment (MSA) is a keystone problem in the sequence analysis that is used for constructing phylogenetic tree, finding motif, gene expression, etc. Basically, all biological computation issues are NP-complete problems. In this paper, a novel approach using Cellular Automata (CA) and Particle Swarm Optimization (PSO) techniques are proposed for MSA problem. Both of these techniques handle NP-complete problems very skillfully. For experimental analysis, the BaliBASE benchmark dataset and two scoring functions Sum of Pairs (SP) and Total Column (TC) are considered in this paper for calculating the similarity among the sequences. Using the Wilcoxon matched pair signed rank test the significance of the proposed algorithm (PSOCA) is explained. This algorithm is compared with PSO, genetic algorithm and the state-of-the-art techniques. The results show that the PSOCA approach yields better performance than other state-of-the-art algorithms.

Authors: Khan Saad Jawaid , Bari Abu Zeeshan , Khan Soobia Saad , Khan Muhammad Tahir
Published: January 2016

The objective of this work is to evaluate the biomechanical effects of footwear on steady state walking of a user. An initial subjective preference of the footwear was identified which was validated biomechanically in relation to the kinetic parameters of gait. The subject underwent 3D gait analysis (using VICON Motion Capture System, UK) under four conditions: barefoot, with formal shoes, with casual shoes and with sandals. ANOVA and Paired t-test of Temporal Spatial Parameters (TSP), joint powers and joint moments (a = 0.05), for the four conditions in sagittal plane showed that there were significant differences found in TSP's, joint moments and work done, but not in joint powers. The behaviour of formal shoes was significantly different in the frontal and transverse plane moments and had the most profound effect on the joints. Although several hypotheses on the implications of footwear on the gait parameters are proposed, these require further investigation, supplemented with electromyography (EMG) and metabolic energy measurements for a larger population.
Pulse Spectrophotometric Determination of Plasma Bilirubin in Newborns
Authors: Michel Erik , Entenmann Andreas , Michel Miriam
Published: January 2016

In neonatal jaundice, plasma bilirubin has to be measured repeatedly in order to direct phototherapy. Invasive determination is standard. The authors delineate a concept for the non-invasive spectrophotometric determination of absolute plasma bilirubin concentration. By referencing the pulsatile spectrophotometric signal component of the metabolite of interest (MOI, here: bilirubin) to the pulsatile spectrophotometric signal component of a reference metabolite (MOR, here: water) of known plasma concentration, the absolute MOI concentration can be calculated. Based on Beer-Lambert's law and some reasonable assumptions, the authors developed a theoretical concept for the calculation of MOI concentration. They suggest light of 1200 nm wavelength to measure MOR, 795 nm and 570 nm to measure hemoglobin as correction signal, and 450 nm to measure the MOI. To enhance data quality one could assign several wavelengths to each metabolite. Since in tissue spectrophotometry Beer-Lambert's law does not reflect physiology accurately, it will be necessary to empirically fine-tune the computer algorithms.

Computer aided engineering can predict failure circumstances, which can be avoided for the health and well-being of people. In this research work, computer aided engineering analysis of human elbow is presented beginning with modeling of human elbow from medical image data, and predicting the stresses in elbow during carrying heavy loads. The analysis is performed by using finite element method. The results predict the stress level and displacement in the human bone during heavy weight lifting. Thus, it can be used to predict the safe load that a particular person can carry without bone injury. The present analysis focused on a particular model of bone for a particular individual. However, safe load can be determined for various age groups by generating more detailed model including tendons, ligaments and by using patient specific material properties.

Published: January 2016

Today's healthcare technology provides promising solutions to cater to the needs of patients. The development of wearable physiological monitoring system has reached home-centric patients by ensuring faster healthcare services. The primary advantage of this system is activation of alarms to alert the specialist in a nearby hospital to attend to any sort of emergency. Specifically, cardiac-related problems need special attention when a 24-hour Holter monitors ECG signals and identifies the level of abnormalities under various circumstances. Although several brands of Holters exist in market, there is a huge demand for digitized Holter recorders. These recorders can simultaneously analyse cardiac signals in real time mode and store the data and reuse them for next 24 hours. As home-centric based wearable cardiac monitoring system gains much attention recently, there is a need to design and develop a cardiac monitoring system by establishing a trade-off between the required clinical diagnostic quality and cost. This research study highlights a comprehensive survey of various cardiac monitoring systems under wire, wireless and wearable modes. This provides an insight into the need of the hour in bringing a cost-effective wearable system. The study provides an insight of the technological aspects of the existing cardiac monitoring system and suggests a viable design suitable for developing countries.

Authors: Papadopoulos Homer
Published: January 2016

The “Unobtrusive Smart Environments for Independent Living” EU funded project is proposing an integrated system (USEFIL system) which intends to cope with ageing problem providing advanced, affordable and unobtrusive monitoring and web communication solutions for seniors living independently. The USEFIL system enhances social care and medical service provision by exploiting “frugal” ICT solutions such as low cost “off-the-shelf” technology and unobtrusive monitoring technologies to develop services that will assist the elderly in maintaining their independence throughout their daily activities. The project adopted the Design Science Research Methodology (DSRM) to design and develop the USEFIL system because this methodology incorporates all those principles, practices, and procedures to help us meet USEFIL systems' objectives. Aim of the paper is to demonstrate the use of the DSRM process to design an ICT solution for the case study of ICT technologies for assistive living environments for elderly people. More specifically using the theoretical lens of the Design Science Research Methodology theory the paper presents the necessary steps that have been conducted to design the USEFIL system. The USEFIL system was implemented and validated over a three year period with elderly people, their unofficial carers and doctors. Results demonstrate that the technology readily succeeds in meeting the study's initial objectives. Although the project is still running and the design specification of the USEFIL system is under continuous update, the main modules that have been designed and realized will be presented in the paper.
A Hybrid Framework for Semantic Relation Extraction over Enterprise Data
Authors: Shen Wei , Wang Jianyong , Luo Ping , Wang Min
Published: January 2016

Relation extraction from the Web data has attracted a lot of attention in recent years. However, little work has been done when it comes to relation extraction from the enterprise data regardless of the urgent needs to such work in real applications (e.g., E-discovery). One distinct characteristic of the enterprise data (in comparison with the Web data) is its low redundancy. Previous work on relation extraction from the Web data largely relies on the data's high redundancy level and thus cannot be applied to the enterprise data effectively. This paper proposes an unsupervised hybrid framework called REACTOR. REACTOR combines a statistical method, classification, and clustering to identify various types of relations among entities appearing in the enterprise data automatically. Furthermore, the authors explore to apply pronominal anaphora resolution to extract more relations expressed across multiple sentences. They evaluate REACTOR over a real-world enterprise data set from HP that contains over three million pages and the experimental results show the effectiveness of REACTOR.

Published: January 2016

Students in the digital era are habitual of using digital devices not only for playing and interacting with their friends and peers, but also as a tool for education and learning. These digital natives are highly obsessed with the internet driven portable devices and always demand for a multimedia rich content. This specific demand needs to be addressed by college teachers in the teaching -learning pedagogy design and implementation. The integration of pervasive computing in traditional classroom pedagogy can boost new learning experience for cyber savvy students in higher education. Learning Management System (LMS) as a pervasive computing can be embedded in classroom pedagogy to support learning inside and outside the classroom. LMS can play a supportive role to teachers and administrators in higher education to facilitate them in their work. This becomes more significant to the teachers and administrators, when the LMS is based upon the cloud computing platform. This paper explores the significance of various components of cloud-based open source Moodle Learning Management System with a specific focus on teachers and administrators in higher education. A learning theory approach has been followed to map the requirements of the teachers and the administrators and specific cases and examples have been presented.

Concrete with Crystalline Admixture for Ventilated Tunnel against Moisture
Authors: Pazderka Jiří
Published: January 2016

The paper deals with the use of concrete with crystalline admixture for special remedial structure which is exposed to intensive ground moisture and high level of air humidity. Additional protection of ground part of older buildings against subsurface water and ground moisture is one of the most important measures to ensure their long-time durability and satisfactory user properties. One of the most used remediation method are the air ducts which principle is to enable air flow along the moist structure surface to allow the sufficient evaporation of moisture from the structure. This group of methods includes also the ventilated underground tunnel along the perimeter walls. Presently the ventilated tunnels are designed as masonry structure whose durability in contact with the ground moisture is limited. The paper introduces a new technical solution of this method based on the special shaped concrete blocks whose durability is ensured by using of concrete with crystalline admixture. The waterproofing effect of the crystalline admixture is declared by the results of laboratory tests (in comparison with efficiency of crystalline coating).

Authors: Fořt Jan , Trník Anton , Pavlík Zbyšek
Published: January 2016

Thermal energy storage represents an important aspect of building energy conservation. Unfortunately, modern buildings with lightweight building envelopes not provide sufficient heat storage capacity and indoor overheating is a common problem, mostly solved by high performance air conditioning that leads to the higher electricity consumption. Here, Phase Change Materials (PCMs) that allow significant heat storage or release when undergo phase transition can find use. On this account, a detailed testing of a new type of cement-lime plaster modified by PCM admixture with respect to the temperature change rate is presented in the paper. The studied material is based on commercial dry plaster mixture that is modified by microencapsulated polymer PCM admixture. For characterization of the developed material, measurement of basic physical and mechanical properties is done. Within the DSC analysis, the researched material is exposed to the temperature loading ranging from 0 °C to 40 °C, with the temperature change rate of 1, 5 and 10 °C/min respectively. On the basis of DSC tests, temperature of phase change and its corresponding enthalpy are determined. The obtained data show the effect of heating and cooling mode on materials performance in the form of a significant shift of DSC curves. This effect is evaluated and applicability of incorporated PCM admixture for the use in thermal energy storage plasters is discussed.

By drills realization in order to obtain petroleum and natural gas, the isolation of the individual layers along the height of drilling activity is the most important factor for judging the serviceability and follow-existence of the finished work. The special cements for drilling are used as plugging material suited according to API Spec. 10A (American Petroleum Institute).Recently, in the institute we have dealt with the impact of the time factor on the pressure characteristics and stress-strain diagrams of samples from the drilling mud additives [1], due to the time factor for composites containing drilled and subsequently in practice applied aggregates [2] and also the characteristics of a drilling cement made for lower and laboratory increased temperatures [3]. In the article we deal with a similar topic. Results for tension and pressure characteristics gathered in time up to 120 hours were used to generate the stress-strain diagrams, static and dynamic modules in compression. Heat background of tests answers the real terms of drilling activities up to 1200 m. In conclusion, we will compare the results with available foreign results.

A Study on the Application of Artificial Neural Networks on Green Self Consolidating Concrete (SCC) under Hot Weather
Authors: Al Khatib Mohamed , Al Martini Samer
Published: January 2016

Self-consolidating concrete (SCC) has recently drawn attention to the construction industry in hot weather countries, due to its high fresh and mechanical properties. The slump flow is routinely used for quality control of SCC. Experiments were conducted by the current authors to investigate the effects of hot weather conditions on the slump flow of SCC. Self-consolidating concrete mixtures were prepared with different dosages of fly ash and superplasticizer and under different ambient temperatures. The results showed that the slump flow of SCC is sensitive to changes in ambient temperature, fly ash dosage, and superplasticizer dosage. In this paper, several artificial neural networks (ANNs) were employed to predict the slump flow of self-consolidating concrete under hot weather. Some of the data used to construct the ANNs models in this paper were collected from the experimental study conducted by the current authors, and other data were gathered from literature. Various parameters including ambient temperature and mixing time were used as inputs during the construction of ANN models. The developed ANN models employed two neural networks: the Feed-Forward Back Propagation (FFBP) and the Cascade Forward Back Propagation (CFBP). Both FFBP and CFBP showed good predictability to the slump flow of SCC mixtures. However, the FFBP network showed a slight better performance than CFBP, where it better predicted the slump flow of SCC than the CFBP network under hot weather. The results in this paper indicate that the ANNs can be employed to help the concrete industry in hot weather to predict the quality of fresh self-consolidating concrete mixes without the need to go through long trial and error testing program.Keywords: Self-consolidating concrete; Neural networks; Hot weather, Feed-forward back-propagation, Cascade-forward back propagation.
Determining Concrete Composition on Recycled Aggregates
Authors: Koper Artur , Koper Marcin , Kubissa Wojciech
Published: January 2016

The problem of recycling of construction wastes is important and at the same time difficult to deal with. One of the possible ways of using the construction wastes coming from the demolition of concrete constructions is to re-use them in the production of construction concretes as recycled concrete aggregates RCA. Determining the concrete composition with the use of RCA demands conditioning its different from the natural aggregates NA physical and mechanical properties. In the procedure of projecting the concrete composition with three equations theory the assumption of consistency class of concrete mixture is demanded. Having accepted it, the water demand of aggregates and cement is determined. In case of natural aggregates NA the formulas of Sterne's and Bolomey's are used in which aggregates water demand is conditioned from its kind and granulation and also from concrete mixture consistency. In case of RCA, there is lack of such data and each time it is necessary to determine the water demand empirically after performing a trial batch. There also exists a necessity to determine the relation between RCA water demand and its other properties which are easy to be determined in laboratory conditions and in short time. Such a property can be measured with the crushing rate wrm resistance of aggregates to crushing. Crushing rate wrm was used to qualify the recycled aggregates from recycling with the point of their potential of being re-used in constructive concrete production. It was determined a relation between crushing rate wrmand the coefficient ARCA taking place in the modified strength equation of Bolomey and thus it became possible to use the method of three equations to project the concrete composition on recycled aggregates.

Hygric Properties of HPC with Natural Pozzolana
Authors: Koťátková Jaroslava , Čáchová Monika , Koňáková Dana , Vejmelková Eva
Published: January 2016

The water vapour transport and the liquid water transport of high performance concrete (HPC) with the content of natural pozzolana are the described in this paper. Studied properties are presented by means of water vapour diffusion coefficient, water vapour diffusion resistance factor and absorption coefficient respectively. The natural pozzolana (NP), namely natural zeolite, is used as supplementary cementitious material which affects the durability properties of the end product. The obtained results revealed the effectiveness of NP in the terms of both studied properties when used in small amounts, i.e. at about 20% of cement weight. On the other hand substitutions higher than 40% result in worsening of the resistance of the concrete to water and water vapour ingress and its movement trough the material.
Carboniferous and Permian subsurface stratigraphy, Prince Patrick Island, Northwest Territories, Canadian Arctic
Authors: Beauchamp B , Harrison J C , Utting J , Brent T
A , Pinard S
Published: January 2016

The Carboniferous and Permian succession of the Sverdrup Basin is extensive in the subsurface of northern Prince Patrick Island of the Canadian Arctic Archipelago, Northwest Territories. The succession is known from a series of seismic profiles and four
exploratory wells drilled during the early 1970s. Upper Paleozoic strata are characterized by two broad packages. The lower package comprises Carboniferous to Lower Permian clastic and carbonate rocks truncated by a number of northwest southeast-trending synsedimentary normal faults. The upper
package is composed of Middle Permian (Guadalupian) clastic rocks that were deposited during a regime of passive subsidence following the cessation of faulting. These strata are separated from the underlying Lower Permian and Carboniferous succession by a widespread and locally angular unconformity.
Eleven upper Paleozoic formations have been identified on Prince Patrick Island: Borup Fiord, Canyon Fiord, Belcher Channel, Nansen, Raanes, Hare Fiord, 'unnamed clastics', Trappers Cove, Sabine Bay, van Hauen, and Trold Fiord. The succession contains eight major unconformities that can be
correlated over a significant area. Five of these unconformities were encountered in three of the drilled wells. Three additional unconformities were observed on seismic profiles only. The eight unconformities and the seven transgressive regressive sequences between them have been traced seismically
using a series of profiles. The ages of these sequences are Serpukhovian(?), Bashkirian Kasimovian, Gzhelian Sakmarian, Sakmarian Artinskian, Kungurian, Roadian Wordian and Capitanian(?). The Carboniferous and Permian geological history of Prince Patrick Island includes a complex succession of
events whereby tectonic pulses, as evidenced by brittle deformation, alternated with episodes of tectonic quiescence and passive subsidence. Climatic conditions evolved from warm and relatively arid during the Bashkirian Sakmarian interval to increasingly cooler during the Artinskian Capitanian(?).
More humid conditions were also established during the Kungurian. A major river system fed the Prince Patrick area with large amounts of clastic material during the Artinksian Guadalupian interval. The current geological setting of the area suggests the presence of many unexplored oil and gas plays.
Unfortunately, the succession lies too deeply in the subsurface to envision any mineral exploration effort in the future.

Mathematical Models for the Propagation of Stress Waves in Elastic Rods: Exact Solutions and Numerical Simulation
Authors: Tenkam H. M. , Shatalov M. , Fedotov I. , Anguelov R.
Published: January 2016

In this work, the Bishop and Love models for longitudinal vibrations are adopted to study the dynamics of isotropic rods with conical and exponential cross-sections. Exact solutions of both models are derived, using appropriate transformations. The analytical solutions of these two models are obtained in terms of generalised hypergeometric functions and Legendre spherical functions respectively. The exact solution of Love model for a rod with exponential cross-section is expressed as a sum of Gauss hypergeometric functions. The models are solved numerically by using the method of lines to reduce the original PDE to a system of ODEs. The accuracy of the numerical approximations is studied in the case of special solutions.

Authors: Huang Fenglin , Chen Yanping , Shi Xiulian
Published: January 2016

In this paper, we investigate the Galerkin spectral approximation for elliptic control problems with integral control and state constraints. Firstly, an a posteriori error estimator is established,which can be acted as the equivalent indicatorwith explicit expression. Secondly, appropriate base functions of the discrete spacesmake it is probable to solve the discrete system. Numerical test indicates the reliability and efficiency of the estimator, and shows the proposed method is competitive for this class of control problems. These discussions can certainly be extended to two- and three-dimensional cases.
A Goal-Oriented Adaptive Moreau-Yosida Algorithm for Control- and State-Constrained Elliptic Control Problems
Authors: Günther Andreas , Tber Moulay Hicham
Published: January 2016

In this work, we develop an adaptive algorithm for solving elliptic optimal control problems with simultaneously appearing state and control constraints. The algorithm combines a Moreau-Yosida technique for handling state constraints with a semi-smooth Newton method for solving the optimality systems of the regularized sub-problems. The state and adjoint variables are discretized using continuous piecewise linear finite elements while a variational discretization concept is applied for the control. To perform the adaptive mesh refinements cycle we derive local error estimators which extend the goal-oriented error approach to our setting. The performance of the overall adaptive solver is assessed by numerical examples.
Rectangular Lattice Boltzmann Equation for Gaseous Microscale Flow
Authors: Ren Junjie , Guo Ping , Guo Zhaoli
Published: January 2016

The lattice Boltzmann equation (LBE) is considered as a promising approach for simulating flows of liquid and gas. Most of LBE studies have been devoted to regular square LBE and few works have focused on the rectangular LBE in the simulation of gaseous microscale flows. In fact, the rectangular LBE, as an alternative and efficient method, has some advantages over the square LBE in simulating flows with certain computational domains of large aspect ratio (e.g., long micro channels). Therefore, in this paper we expand the application scopes of the rectangular LBE to gaseous microscale flow. The kinetic boundary conditions for the rectangular LBE with a multiple-relaxation-time (MRT) collision operator, i.e., the combined bounce-back/specular-reflection (CBBSR) boundary condition and the discrete Maxwell's diffuse-reflection (DMDR) boundary condition, are studied in detail. We observe some discrete effects in both the CBBSR and DMDR boundary conditions for the rectangular LBE and present a reasonable approach to overcome these discrete effects in the two boundary conditions. It is found that the DMDR boundary condition for the square MRT-LBE can not realize the real fully diffusive boundary condition, while the DMDR boundary condition for the rectangular MRT-LBE with the grid aspect ratio a≠1 can do it well. Some numerical tests are implemented to validate the presented theoretical analysis. In addition, the computational efficiency and relative difference between the rectangular LBE and the square LBE are analyzed in detail. The rectangular LBE is found to be an efficient method for simulating the gaseous microscale flows in domains with large aspect ratios.
A Numerical Method on Eulerian Grids for Two-Phase Compressible Flow

Published: January 2016

We develop a numerical method to simulate a two-phase compressible flow with sharp phase interface on Eulerian grids. The scheme makes use of a levelset to depict the phase interface numerically. The overall scheme is basically a finite volume scheme. By approximately solving a two-phase Riemann problem on the phase interface, the normal phase interface velocity and the pressure are obtained, which is used to update the phase interface and calculate the numerical flux between the flows of two different phases. We adopt an aggregation algorithm to build cell patches around the phase interface to remove the numerical instability due to the breakdown of the CFL constraint by the cell fragments given by the phase interface depicted using the levelset function. The proposed scheme can handle problems with tangential sliping on the phase interface, topological change of the phase interface and extreme contrast in material parameters in a natural way. Though the perfect conservation of the mass, momentum and energy in global is not achieved, it can be quantitatively identified in what extent the global conservation is spoiled. Some numerical examples are presented to validate the numerical method developed.

A novel generalised successive overrelaxation (GSOR) method for solving generalised saddle point problems is proposed, based on splitting the coefficient matrix. The proposed method is shown to converge under suitable restrictions on the iteration parameters, and we present some illustrative numerical results.
Submatrix Constrained Inverse Eigenvalue Problem involving Generalised Centrohermitian Matrices in Vibrating Structural Model Correction
Authors: Xu Wei-Ru , Chen Guo-Liang
Published: January 2016

Generalised centrohermitian and skew-centrohermitian matrices arise in a variety of applications in different fields. Based on the vibrating structure equationwhereM, D, G, Kare given matrices with appropriate sizes andxis a column vector, we design a new vibrating structure mode. This mode can be discretised as the left and right inverse eigenvalue problem of a certain structured matrix. When the structured matrix is generalised centrohermitian, we discuss its left and right inverse eigenvalue problem with a submatrix constraint, and then get necessary and sufficient conditions such that the problem is solvable. A general representation of the solutions is presented, and an analytical expression for the solution of the optimal approximation problem in the Frobenius norm is obtained. Finally, the corresponding algorithm to compute the unique optimal approximate solution is presented, and we provide an illustrative numerical example.

Learning Activities Utilized and Readiness for the Student Teaching Internship

Agricultural education has traditionally provided rich learning experiences for secondary school students; however, less attention has been paid to the learning experiences preservice agricultural education teachers utilize and provide secondary school students during the student teaching internship. This study sought to describe the learning activities preservice teachers utilize during instruction and assess preservice teachers’ self-perception of preparedness in technical content knowledge and teaching methods after completing their student teaching internship. A majority of the preservice teachers used student-centered activities with the greatest frequency, and did not rely on one category of learning activities a majority of the time. This finding is encouraging since variety is a characteristic of effective teaching, and the types of learning activities utilized support the philosophical beliefs of agricultural education. On the other hand, preservice teachers identified agricultural mechanics, biotechnology, wildlife and fisheries management, and veterinary science as technical content areas in which they possessed less than appropriate content knowledge. A majority of the preservice teachers also perceived themselves as not prepared in instructional methods for wildlife and fisheries management and veterinary sciences. We recommend these technical content areas and pedagogical deficiencies be considered high priorities when developing in-service professional development for new teachers in Florida.
Meta-analysis of intramuscular fatty acid composition of Mediterranean lambs

Published: January 2016

Abstract. The aim of this work was to study the intramuscular fatty acid profile of Mediterranean lambs using a meta-analysis. The database was created from five journal articles and one doctoral dissertation, and included lambs of the Talaverana, Comisana, Churra Tensina, Merino Branco and Pramenka breeds. All analyses were performed using Comprehensive Meta-Analysis and R statistical software. According to the overall pooled result, lambs of Mediterranean breeds included in our meta-analysis had 22.85 % of palmitic (C16:0), 14.78 % of stearic (C18:0) and 5.32 % of myristic acid (C14:0). The overall pooled result for oleic acid (C18:1) was 32.53 %, and it was 5.60 % for linoleic acid (C18:2 n-6) and 1.95 % for α-linolenic acid (C18:3 n-3). Regardless of the proportions of the main fatty acids, Mediterranean lambs had 47.85 % of SFA (saturated fatty acid), 37.87 % of MUFA (monounsaturated fatty acid) and 11.50 % of PUFA (polyunsaturated fatty acid). The overall pooled result for the PUFA / SFA ratio was 0.23, and it was 2.22 for the n-6 /n-3 ratio. The results of our meta-analysis enabled us to gain an important scientific insight into the lipid profile of intramuscular fat in Mediterranean lambs. A systematic combination of quantitative data from several carefully selected studies provided estimates of greater statistical power and enabled a more truthful comparison of results originating from different independent studies than any previously published research on this issue.
