Published: September 2016

The efficiency of Cu2+ ion extraction of magnetically labeled biosorbent based on yeast Sacharomyces cerevisiae obtained by magnetohydrodynamic stirring in combined magnetic and electric fields has been determined. The effect of different concentration of magnetic nanoparticles and yeast cells on the magnetic susceptibility was determined. Optimal magnetite content is 1 %, as such biosorbent has a maximum magnetic susceptibility and the best stability. The higher sorption capacity is observed for magnetically labeled biosorbent obtained through the magnetohydrodynamic stirring in the combined magnetic and electric field with concentration of magnetite 1 %.

The process of active and passive biosorption shows that part of the magnetite nanoparticles has been attached to the surface of biosorbent. This indicates that both passive and active sorption takes place in the process of interaction of yeast cells and magnetite nanoparticles.

Authors: Ashkan Khodabandehlou , Vahid Saleh Haghgou
Published: September 2016

Regarding the performance of Nano-silica in cement based materials such as cement paste, mortar and concrete there are different outcomes revealed by researchers that fluctuates around significant increase or decrease in resistance of due materials. In the present research the impact of different kinds of Nano-silica whether powder or colloids form and special plane with 80 to 500 m2/ gr on characteristics of new and hardened mortar has been investigated. The results indicated that Nano-silica contributes to dramatic decrease in performanceality. As such, to compensate the loss one needs to use super plasticizer. Using Nano-silica increases pressure resistance regarding control mortar and in some cases the level of pressure is more than mortar containing silica fume. Also the majority of increase in Nano-silica resistance takes place during seven days. The size of Nano-silica particles in this research was evaluated by Transmission Electron Microscopy (TEM).

Authors: Ren Bin , Hao Rujiang , Yang Shaopu
Published: September 2016

Drive system is one of most important key equipment to guarantee safe and stable operation in locomotive. With time variation, unpredictability and nonstationary, fault source of drive system is not obtained by traditional fault diagnosis method. Blind source separation is a kind of method on source signals separation under transmission channel unknown instance. The method of Blind source separation based on variable metric empirical mode decomposition is proposed. Intrinsic mode function is built, redundancy factors are reduced, and recurrent neural network is used to adaptive blind separation. The method is verified by data analysis of on-line measuring. The results show that separation efficiency is improved and unaffected with iteration time in the process of fault information separation, which will be better for further fundamental research and provide technique support for the locomotive.

Authors: Weng Falu , Ding Yuanchun , Mao Weijie
Published: September 2016

The tuned mass damper parameters designing for structural systems based on combining linear matrix inequality with genetic algorithm is of concern in this paper. Firstly, based on matrix transform, the novel model description with a singular style for structural systems is obtained, in which the possible coupling of those uncertainties is avoided. Secondly, an approach, which combines linear matrix inequality with genetic algorithm, is taken in this work to solving the optimization problems, and the optimized tuned mass damper parameters can be obtained by solving the optimization problems such that the tuned-mass-damper-controlled systems have a prescribed level of vibration attenuation performance. Furthermore, the obtained results are also extended to the uncertain cases. Finally, the effectiveness of the obtained theorems is demonstrated by numerical simulation results.
Numerical computation of wheel-rail impact noises with considering wheel flats based on the boundary element method
Authors: Cui Kai , Qin Xiaotong
Published: September 2016

When a wheel rolls to a flat, it can generate the impact force several multiples larger than that generated at the common time. The paper established a wheel-rail coupling vibration model with wheel flat, and vibration acceleration responses of the rail was computed. The computational result was then compared with the experimental result. Good consistency between simulation and experiment indicated that the finite element model is reliable. Then, based on the finite element model and boundary element model, the paper established a structural-acoustic coupling boundary element model and computed the radiation noise of wheel-rail under effects of wheel flats. Results show that: the wheel flats were an important reason for wheel rail impact noises, impact noises of wheel flats were mainly concentrated in frequency bands of over 250 Hz, and impact noises of wheel flats were closely related with wheel flat length, quantity of wheel flats as well as running speeds. With the increase of these parameters, the radiation noise of wheel flats would be increased correspondingly.

To characterize the ELISE project, a concept robot applicable in the neuro-rehabilitation of the entire paretic upper limb. The project has been designed and implemented based on comprehensive rehabilitation of the shoulder, forearm and hand. ELISE is a concept robotic system prepared for individualized approach in rehabilitation of stroke patients including diagnostics, passive and/or active exercises and reports. The ELISE system includes dual biofeedback solutions: rehabilitation exercises in virtual reality (VR) and the virtual assistant of therapist. The biomechanical, ergonomics, electrical/electronics, hardware/software aspects of the design are described in detail here. This paper suggests a new approach to rehabilitation robots for the spastic upper limb of stroke survivors. Rehabilitation with ELISE robot was based on movement exercises, which incorporate biofeedback in VR. The patient realizes common tasks from ordinary life. This innovative rehabilitation connects practical/social aspect of rehabilitation with movement exercises. With the aid of these stimulations, the ELISE robot is intended to speed up the process of recovery from damaged neuron connections in brain. Robot was designed for flexible assembly and can be tailored to individual needs and unique expectations of each therapist and patient. This is possible thanks to the modular design of the robot arm and software. The ELISE robot will be sold in different configurations (e.g. without an expander or a set of virtual games or a virtual assistant of therapist).
A rolling bearing fault diagnosis method based on VMD – multiscale fractal dimension/energy and optimized support vector machine
Authors: Chen Fei , Chen Xiaojuan , Yang Zhaojun , Xu Binbin , Xie Qunya , Zhang Heng , Ye Yifeng
Published: September 2016

To achieve the goal of automated rolling bearing fault diagnosis, a variational mode decomposition (VMD) based diagnosis scheme was proposed. VMD was firstly used to decompose the vibration signals into a series of band-limited intrinsic mode functions (BLIMFs). Subsequently, the multiscale fractal dimension (MSFD) and multiscale energy (MSEN) of each BLIMF were calculated and combined together as features of the original vibration signals. In an attempt to accelerate the classification speed, one-way analysis of variance (ANOVA) test was adopted to extract significant features from the redundant features. Finally, those significant features were fed into the optimized support vector machine (SVM), which was optimized by the genetic algorithm (GA), for classification. Experimental results on the international public Case Western Reserve University bearing data indicate the effectiveness of the proposed method with a classification accuracy of 99.75 % for seven classes. Moreover, our approach also shows good anti-noise performance in different signal-to-noise ratios (SNRs).

However, the extracted original features still with high dimensional and include superfluous information, the multi-features fusion technique principal component analysis (PCA) is used to merge the features and reduce the dimension. And the bearing degradation indicator is constructed based on the first principal component, which can indicate the bearing early failure state precisely. Then, based on the life condition indicator, the weighted complex SVM model is used to achieve the bearing remain life prediction, in this model, the particle swarm algorithm (PSO) method is used to select the SVM internal parameters, the phase space reconstruction algorithm is used to determine the structure of the SVM. Cases of actual were analyzed, the results proved the effectiveness of the methodology.
Seismic performance of functionally graded diagonal braced structures
Authors: Kandemir-Mazanoglu Elif Cagda
Published: September 2016

This paper investigates the usage of functionally graded beam as a bracing member in building-type structures subjected to severe ground motions. Material distribution of functionally graded beam follows power law form along thickness direction. Equivalent stiffness of functionally graded brace (FGBr) is derived and confirmed analytically through applying strain energy equilibrium and appropriate boundary conditions on Euler-Bernoulli beam element for simulation of brace behavior. The seismic response analyses of single and multi-storey shear-type buildings with FGBrs are performed on lumped mass-stiffness models. This modeling technique is validated in terms of fundamental natural periods by continuous and numerical solutions. The effect of varied Young’s modulus and power law exponent on maximum responses such as displacement, storey drift and base shear is evaluated under both harmonic and severe earthquake motions.
Hopf bifurcation analysis and control of three-dimensional Prescott neuron model
Authors: Yuan Chunhua , Wang Jiang
Published: September 2016

Neurons generate different firing patterns because of different bifurcations in the dynamical viewpoint. Various nerve diseases are relevant to the bifurcation of nervous system. Therefore, it is vital to control bifurcation since it may be potential ways of treating nerve diseases. This paper focuses on the critical Hopf bifurcation analysis and the problem of Hopf bifurcation control. We investigate the effects of key parameters on critical Hopf bifurcation and obtain the Hopf bifurcation occurrence region on parameter plane. With the theory of high-dimensional Hopf bifurcation, we analytically deduce the judgement criteria of Hopf bifurcation type for the three-dimensional models and judge the Hopf bifurcation type of Prescott model by using it. With application of the Washout filter, the subcritical Hopf bifurcation of Prescott model is controlled and converted to supercritical Hopf bifurcation. In addition, we make some discussions on Hopf bifurcation analysis of a coupled neural network. The results provided in this paper could bring new ways to controlling neurological diseases.
Nonlinear dynamic model and vibration response of faulty outer and inner race rolling element bearings
Authors: Shi Peiming , Su Xiao , Han Dongying
Published: September 2016

By considering the deep groove ball bearing as the research object, and using Hertzian contact theory and elastic mechanics and geometry, a nonlinear dynamic model is established herein for the study of vibration response of deep groove ball bearings having single defect on surfaces of inner and outer races. The outer race and inner race defect size parameters are introduced into this nonlinear dynamic model, and dynamic models of localized fault on outer race, inner race of rolling element bearing are simulated and analyzed by using Runge-Kutta method. Both simulated and experimental localized fault signals (acceleration signals) are subjected to the same diagnostic techniques; namely time domain waveform comparisons and envelope analysis. Then, the impact characteristic that reflects the fault severity in rolling element bearings is obtained from the time interval between two impact points. The simulating results are in accordance with experimental results, which proves the accuracy and practicality of the models used in engineering application. The characteristic defect frequencies and related harmonics are broadly investigated and presented herein. This proposed model provides theoretical basis for monitoring and fault diagnosis of rolling bears.
Experimental investigation of the vibration-attenuating effect of rail suspension fasteners on environment vibration induced by subway
Authors: Wang Ping , Wei Kai , Liang Yingchun , Wang Feng
Published: September 2016

A field test of environment vibration due to subway was carried out so as to investigate the vibration-alleviating effect of rail suspension fasteners in both time and frequency domains. The experimental results show that the time-domain vertical ground vibration accelerations would transform from several concentrated vibrations to the decentralized and uniform ones after replacement of common rail fasteners with rail suspension fasteners. Moreover, rail suspension fasteners have more significant vibration-mitigation effect on the time-domain peak particle accelerations (PPAs) at the nearer positions than at the farther ones, and the minimum PPA induced by common rail fasteners is still higher than the maximal PPA caused by rail suspension fasteners at all measuring positions. In frequency domain, the vibration-reduction effect of rail suspension fasteners is more remarkable in the dominant 1/3 octave center frequencies of 50-125 Hz than in the non-dominant ones from 1 to 40 Hz. Compared with common rail fasteners, the highest vibration acceleration levels (VALmax) in the dominant 1/3 octave center frequencies between 50 and 125 Hz at all measuring positions decrease by 8.7-21 dB after adoption of rail suspension fasteners. Additionally, the integrated VLzs in 1/3 octave center frequencies of 1-125 Hz at all measuring positions are ranged from 77.1 dB to 66.5 dB, evidently higher than the China’ standard threshold of 65 dB, before replacement of common rail fasteners, while the integrated VLzs are framed between 68.3 and 57.3 dB, mostly less than the threshold, after application of rail suspension fasteners.

Published: September 2016

A non-pneumatic tire appears to have advantages over the conventional pneumatic tire in terms of flat proof and maintenance free. A mechanical elastic wheel (MEW) with a non-pneumatic elastic outer ring which functions as the air of the pneumatic tire was presented. The structure of MEW is non-inflatable integrated configuration and the effect of hinges is accounted for only in tension. To establish finite element model of MEW, various nonlinear factors, such as the geometrical nonlinearity, material nonlinearity and contact nonlinearity, were considered. Load characteristic test was conducted by tyre dynamic test-bed to obtain force-deflection curves. And the validity of the finite element model was validated through load characteristic test. The vehicle vibration performance respectively based on the MEW and the radial tire was compatative studied under pulse input experiment conditions. The result showed that the vehicle concluding the new mechanical elastic wheel met the vibration performance requirements and vibration performance regularity of pneumatic tire. The results could be used as the thesis reference for the improvement of new mechanical elastic wheel.

Authors: Li Zhengminqing , Wang Jing , Zhu Rupeng
Published: September 2016

Face gear drives in first-stage gear drives of helicopter main gearboxes occupy several strong points versus traditional spiral bevel gear drives, and are addressed by many scholars. However, face gear vibration suppressions, such as calculation solutions of face gear dynamics associated with tooth profile modifications and influences of tooth profile modifications on face gear dynamic behaviors, are not to be investigated, according to the limited published issues. Thus, in the study, influence mechanisms of two version tooth profile modifications, namely, linear addendum modifications of face gears and arcuate dedendum modifications of pinions, on face gear dynamic base parameters, such as mesh stiffness and static transmission errors, are discussed, and calculation solutions of two version tooth profile modifications are constructed. Meanwhile, an equivalent evaluation solution between linear addendum modifications of face gears and arcuate dedendum modifications of pinions is proposed, and a four degree-of-freedom dynamic model of face gear drives is established. Furthermore, dynamic behaviors of an example case of face gear drives associated with two version tooth profile modifications are simulated. The results indicate dynamic behavior crises of face gear drives would not to be caused by two version tooth profile modifications, and when two version tooth profile modifications are equivalent, the effect of linear addendum modifications of face gears on dynamic mesh force suppressions at whole frequencies is better than that caused by arcuate dedendum modifications of pinions, while, as for mesh frequency, the dynamic mesh force suppression effect caused by arcuate dedendum modifications of pinions is better, and considered dynamic mesh force suppression average values associated with two version tooth profile modifications, arcuate dedendum modifications of pinions are recommended. These contributions would improve modification developments and engineering applications of face gear drives in the future.
Discrete entropy theory for optimal redesigning of salinity monitoring network in San Francisco bay
Authors: Boroumand Amir , Rajaee Taher
Published: September 2016

The paper presents an entropy-based method for designing an optimum bay water salinity monitoring network in San Francisco bay (S.F. bay) considering maximum-monitoring-information and minimum-data-lost criteria. Due to cost concerns, it is necessary to design the optimal salinity monitoring network with a minimal number of sampling stations to provide reliable data. The monthly data recorded from January 1995 to December 2014 were obtained over 37 active stations located in S.F. bay and is applied in the research. Transinformation entropy in discrete mode is used to calculate the stations' optimum distance. The discrete approach uses the frequency table to calculate transinformation measures. After calculating these measures, a transinformation–distance (T-D) curve is developed. Then, the optimum distance between salinity monitoring stations is elicited from the curve. The study shows that the S.F. bay salinity monitoring stations provide redundant information and the existing stations can be reduced to 21 with an approximate distance of 7.5 km. The coverage of the proposed monitoring network by using the optimum distance is complete and the system does not generate redundant data. The results of this research indicate that transinformation entropy is a promising method for the design of monitoring networks in bays such as those found in San Francisco bay.

Aeration is an essential component of aerobic biological wastewater treatment and is the largest energy consumer at most water resource recovery facilities. Most modelling studies neglect the inherent complexity of the aeration systems used. Typically, the blowers, air piping, and diffusers are not modelled in detail, completely mixed reactors in a series are used to represent plug-flow reactors, and empirical correlations are used to describe the impact of operating conditions on bubble formation and transport, and oxygen transfer from the bubbles to the bulk liquid. However, the mechanisms involved are very complex in nature and require significant research efforts. This contribution highlights why and where there is a need for more detail in the different aspects of the aeration system and compiles recent efforts to develop physical models of the entire aeration system (blower, valves, air piping and diffusers), as well as adding rigour to the oxygen transfer efficiency modelling (impact of viscosity, bubble size distribution, shear and hydrodynamics). As a result of these model extensions, more realistic predictions of dissolved oxygen profiles and energy consumption have been achieved. Finally, the current needs for further model development are highlighted.

Authors: Brüne Sabrina , Bidarra Zelimar Soares
Published: September 2016

O objetivo deste artigo é o de analisar os impactos diretos (no curto prazo) gerados pela Universidade Federal do Paraná, localizada em Palotina, e pela Universidade Tecnológica Federal do Paraná, de Toledo, que aderiram ao Programa de Apoio a Planos de Reestruturação e Expansão das Universidades Federais (Reuni) nas cidades que as hospedam e a influência desses impactos na economia local. A opção por trabalhar com os efeitos econômicos do Reuni se deu pelo fato de o tema ter sido pouco explorado em pesquisas acadêmicas até então. Parte-se do pressuposto de que as universidades são instituições com relevância econômica para os municípios e, portanto, contribuem ativamente para o desenvolvimento local.  A metodologia utilizada é um estudo de caso comparativo entre as duas IES, e o principal instrumento de coleta de dados foi o questionário. Espera-se demonstrar que as universidades são organizações dinamizadoras da economia local.

Published: September 2016

Indices of lipid peroxidation (LPO), middle weight molecules (MWM), and changes in the structure of the liver and the impact of Reamberin solution on them were analyzed in 202 patients with acute small intestinal obstruction (ASIO) and model of small intestinal obstruction (SIO) in 40 Vietnamese pigs. Endogenous intoxication indices were established to increase along with the increase in enteral deficiency. In case of ASIO increase in lipid peroxidation products,  MWM in serum,  and  decrease in ceruloplasmin  securities,  significant  changes  in  the  liver  (destruction of granular and smooth endoplasmic reticulum, mitochondria, hepatocytes nuclei) were observed. Surgical resolution of ASIO leads to further temporary deterioration of liver structure, increase in MWM, and indices of lipid peroxidation and decrease in ceruloplasmin levels. Prescription of antioxidant therapy in the postoperative period promotes reparative processes in hepatocytes and leads to normalization of endogenous intoxication indices in blood serum and helps reduce postoperative mortality.

Authors: Oni Oluwafemi Emmanuel , Mbangula Kamati I. , Davidson Innocent E.
Published: September 2016

High Voltage Direct Current (HVDC) systems has been an alternative method of transmitting electric power from one location to another with some inherent advantages over AC transmission systems. The efficiency and rated power carrying capacity of direct current transmission lines highly depends on the converter used in transforming the current from one form to another (AC to DC and vice versa). A well configured converter reduces harmonics, increases power transfer capabilities, and reliability in that it offers high tolerance to fault along the line. Different HVDC converter topologies have been proposed, built and utilised all over the world. The two dominant types are the line commutated converter LCC and the voltage source converter VSC. This review paper evaluates these two types of converters, their operational characteristics, power rating capability, control capability and losses. The balance of the paper addresses their applications, advantages, limitations and latest developments with these technologies.

Objective: For some esthetic clinical situations, it is necessary to finish crown margins on direct restorative materials to preserve tissue integrity, bonding integrity, and biological width. The purpose of this research was to investigate microleakage at the interface between bonded lithium disilicate crowns and various direct restorative materials in a class III and class V position.

Methods and Materials: Class III or class V restorations were prepared on one side of extracted incisors with either Tetric EvoCeram, Tetric Evoceram Bulk, Fuji II LC, or Tetric Evoflow. The teeth were prepared for and received a lithium disilicate crown. After load fatiguing, the specimens were thermo-cycled with a fuchsin dye and sectioned. The depth and area of dye penetration were measured with a dimensional grid in micrometers using stereomicroscopy and reported as mean dye depth and area (μm) ± SD. The comparison of multiple categorical independent variables with ratio scale dependent variables was evaluated with an analysis of variance and Tukey's post hoc analysis.

Results: A statistically significant higher dye penetration was noted for all treatment groups compared with the positive control (side opposite the restoration after sagittal sectioning was used as positive control) regardless of material or placement area (p<0.05). In comparing treatment groups, the Tetric EvoFlow experienced a statistically higher dye penetration than did the other treatment groups regardless of material or placement area (p<0.05). There was no statistically significant difference between the Tetric EvoCeram, Tetric Evoceram Bulk, and Fuji II LC materials regardless of placement area (p>0.05).

Conclusions: Within the limitations of this study, it can be concluded that flowable composite materials as finish lines that interact with resin cements could lead to exacerbated interfacial degradation. Finishing lithium disilicate all-ceramic crowns on flowable resin composite materials in the esthetic zone should be used with caution. If necessary, finishing lithium disilicate all-ceramic crowns on nanofilled resin composite or resin-modified glass ionomer materials seems to provide the least dye penetration depth and area.

Objectives: To evaluate the effect of different surface treatments on the bond strength to a composite and a polymer-infiltrated ceramic CAD/CAM block after six-month artificial aging.

Methods and Materials: Two types of CAD/CAM blocks (Cerasmart, GC; Enamic, Vita Zahnfabrik) were cut in slabs of 4-mm thickness, divided into six groups, and subjected to the following surface treatments: group 1: no treatment; group 2: sandblasting (SB); group 3: SB + silane (Si); group 4: SB + Si + flowable composite (see below); group 5: 5% hydrofluoric acid etching (HF) + Si; and group 6: 37% phosphoric acid etching (H3PO4) + Si. Sections of the same group were luted together (n=3: 3 sandwich specimens/group) using a dual-cure self-adhesive cement for all groups, except for the sections of group 4 that were luted using a light-curing flowable composite. After three weeks of storage in 0.5% chloramine at 37°C, the sandwich specimens were sectioned in rectangular microspecimens and trimmed at the interface to a dumbbell shape (1.1-mm diameter). One half of the specimens was subjected to a microtensile bond strength (μTBS) test, and the other half was tested after six months of water storage (aging). Data were statistically analyzed with a linear mixed-effects model for the factors surface treatment, material type, and aging, together with their first-degree interactions (α=0.05).

Results: The lowest bond strengths were obtained in the absence of any surface treatment (group 1), while the highest μTBSs were obtained when the surface was roughened by either SB or HF, this in combination with chemical adhesion through Si. Loss in bond strength was observed after six-month aging when either surface roughening or silanization, or both, were omitted.

Conclusions: Both the composite and polymer-infiltrated ceramic CAD/CAM blocks appeared equally bonding-receptive regardless of the surface treatment used. Creating a microretentive surface by either SB or HF, followed by chemical adhesion using Si, is mandatory to maintain the bond strength after six months.

Purpose: To investigate the effect of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser irradiation pretreatment on the long-term bond strength of an etch-and-rinse adhesive to dentin.

Methods: Fifty molars were sectioned parallel to the occlusal plane and randomly divided into two groups (n=25 per group): control group (no treatment) and laser group (dentin surfaces were treated with Nd:YAG laser at a setting of 100 mJ/10 Hz). Afterward, resin was bonded to the dentin surface using a two-step etch-and-rinse adhesive (Adper SingleBond 2), and then 150 beams of each group were produced. Each group was divided into three subgroups (n=50 each group): 24 hours of water storage, thermocycling, and NaOCl storage. The microtensile bond strength (MTBS), failure modes, nanoleakage expression, and Masson's trichrome staining were evaluated. An additional 20 molars were sectioned to obtain 2-mm-thick flat dentin slices. These slices were randomly divided into control and laser-treated groups as mentioned previously. Then slices of each group were examined by scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), and the Knoop hardness test.

Results: The results of ATR-FTIR and Masson's trichrome verified that laser irradiation partly removed collagen fibers from the dentin surface; however, no significant difference was found in the Knoop hardness (p>0.05). The XRD result showed similar crystalline structure regardless of laser pretreatment. There is no significant difference in short-term MTBS between control and laser-treated groups (p>0.05); however, long-term MTBS differed between the groups (p>0.05). Furthermore, the laser-treated group showed less silver deposition than the control group after aging (p<0.05).

Conclusion: Pretreatment by Nd:YAG laser irradiation appeared to have a positive effect on the adhesive-dentin bonding in vitro test, and the bonding effectiveness could be preserved after aging.
Women Entrepreneurship and Innovations: A Critical Analysis

Published: September 2016

Increased female entrepreneurial activity heralds a progress for women’s rights and optimization of their economic and social living index. Women entrepreneurship is synonymous with women empowerment. Parallel to the male counterparts, female entrepreneurs are catalytic in job creation, innovation and more than tangible contribution to the GNP of the country. An economy thrives when women get a level playing field as men. Innovation works as a catalyst or an instrument for entrepreneurship. Despite all the social hurdles stand tall from the rest of the crowd and are applauded for their achievements in their respective field. The transformation of social fabric of the society, in terms of increased educational status of women and varied aspirations for better living, necessitated a change in the life style of women. This paper endeavors to explore studies related to women entrepreneurship and innovation and how it leads to success and growth of an enterprise.AAcademic Voices Vol.5 2015: 16-21

In ovo exposure of Eurycoma longifolia extract on the pre-hatched development of chicken embryo
Authors: Rahman MS , Yuen LC , Hasan NNRN
Published: September 2016

This study was conducted to investigate the effects of in ovo administration of Eurycoma longifolia (Tongkat Ali) extract (TAE) on the survivability and pre hatch development of chicken embryo. A dose response study of 0.1 mg, 1 mg and 10 mg TAE/100g egg on embryo survivability during first 5 days of incubation showed that the 0.1 to 1mg exposures had no effect on embryo survivability, and the lethal dose to kill 50% (LD50) was at around 10 mg. The 0.1 mg exposure was found to be non-lethal to the developing embryo until 19th day of incubation and it also enhanced (p<0.05) the somite development (42 in TAE and 38 in control embryos) in 88 to 96 hours embryo. Then 0.1 mg TAE exposure resulted in 70.5% body mass gain (% to egg weight) in the 19th day embryo in contrast to53.4% in the control. Compared to control, significant increases in limb lengths and feather-follicles in 9-day old embryos were observed in the 0.1 mg TAE group. On 19th day of incubation, the 100% of the 0.1mg TAE exposed embryos were found to produce traceable vocal sounds along with the pipping marks on egg shell, but these phenomena were almost absent in the control chicks during the same period of incubation. Results suggested that the TAE exposure at >1 mg/100 egg dose is lethal to developing chicken embryo, but the 0.1 mg TAE/100g egg exposure through in ovo injection can be a beneficial strategy to produce heavier and stronger day old chicks.Bang.
