This research has carried out the analysis of the efficiency of natural light as an interior lighting system through fiber optic transmission in Paraguay as a pioneering alternative to energy demand. For its analysis, the construction of a flat concentrator in the shape of a truncated pyramid was carried out, with a metal support equipped with rotational movements both in the x and y planes in such a way as to manually track the sun. At the light concentration point, a support was placed for the 6mm diameter and 10-meter-long optical fiber that transports the concentrated light from one end to the other. This light transmission was measured with a luxmeter to determine the amount of illumination from the concentration point to the end of the fiber. It has been observed that, for an illuminance of 109,200 lux coming from the source (sun) with an orientation of 40° North and with an inclination of 27° with respect to the normal, the illuminance obtained at the end of the fiber located in a totally isolated room of the source was 21,600 lux at the surface of the optical fiber. In addition, the light beam projected by the optical fiber has an opening angle of 60°. Given that the room to be illuminated with the natural light source has artificial light that projects an illuminance of 80,800 lux on the surface of the lamp, it is estimated that 8 (eight) points of natural light will be necessary for said room for adequate lighting.

The study aims to improve the properties of biodegradable films based on chitosan and raphia fiber by adding starch polymer. The biocomposite films were prepared by various proportions of starch (30, 40, 50, 60 and 70% by weight starch) to biocomposite using the solvent casting process by incorporating same percentage raphia fibers with unidirectional weaving. All the samples were analyzed for their mechanical behavior, their morphological property. The biocomposite films were evaluated by measuring tensile strength, young modulus and elongation at break. Elongation at break also increases significantly with the addition of starch, the maximum value of 4.47% was obtained with a film containing 60% by weight of starch. The tensile strength and Young’s modulus of composite films containing 60% by weight of starch show better performance. [ABSTRACT FROM AUTHOR]

In this pioneering study, Retama monosperma fibers were used in the preparation of a plaster composite dedicated to the field of civil engineering in order to find a substitute for fiberglass as a reinforcement material. Retama monosperma (Rtam) is one of the plant species abundantly available in Mediterranean regions. The localization of fibers at the organic level, the extraction procedure, physical and mechanical properties were studied to compare them with other vegetable fibers currently used in the manufacture of biocomposites. The results obtained show the possibility of improving the mechanical properties of plaster by using the fibers of Retama monosperma. The purpose of this paper is to promote the fibers of Retama monosperma as a building material in civil engineering in order to boost researchers' interests in this Mediterranean plant.

Low cost carbon fiber from lignin is a promising biobased feedstock since lignin is by product in many industries. In the present work spinning of concentrated solution of lignin blended with polyacrylonitrile copolymer have been investigated. The wet spinning experiments of PAN/Lignin blend solution to obtain the precursor fiber in continuous form have been successfully demonstrated. Rheological measurements are carried out to optimize the wet spinning process parameters such as to ascertain the dissolution and extrusion temperature. The gel formation temperature of PAN/Lignin blend solutions are determined by the plot of tan δ Vs temperature plot. The FTIR analysis confirms that there is no discernible chemical reaction or crosslinking between PAN and lignin. The resulting precursor fiber from PAN/Lignin blend solution displayed a tensile strength and modulus of 2.36 gpd and 76 gpd respectively. [ABSTRACT FROM AUTHOR]

The last decade has witnessed a tremendous growth of research and development in flexible and wearable strain sensors. However, there are still some challenges associated with the fabrication of strain sensors to achieve a high sensitivity and large workable range at low cost. Here, we report on the development of a highly elastic strain sensor based on a commercial spandex fiber coated with a nanocomposite consisting of multi-walled carbon nanotubes (MWCNTs) and thermoplastic polyurethane (TPU) manufactured by a layer-by-layer (LBL) method. The sensor demonstrated outstanding performance with large workable strain, high sensitivity, excellent repeatability and regular signal responses within a wide measuring frequency range of 0.01~1 Hz. Additionally, the effect of ultraviolet irradiation on the sensor performance was also investigated. Applications of the sensor in monitoring diverse human motions, such as facial microexpressions and speech recognition are also demonstrated, showing its potential for applications in wearable devices and intelligent robots.

The present paper deals with an important issue for the present digital world, namely the quality control of the optic fiber used in transmitting the internet, television, landline or mobile telephony and other digital content connection. Romania, the country with one of the most developed high-speed internet networks in the world, needs modern methods to test the fiber already in use, the one to be installed, as well as the welded connections between them. The paper presents the theoretical model of transmitting information through optic fiber and the possible problems to occur in manufacturing, in operation, when installing or when the connections are made. Experimental plans have been developed and presented to detect the most common types of possible defects, both by destructive and non-destructive methods. In the end, the control parameters and investigation methods have been optimized so that all defects with the highest probability of occurrence are detected by using them. The conclusions of the paper review the quality conditions that fibers must meet for optimal signal transmission by studying the variation of their optical parameters. [ABSTRACT FROM AUTHOR]

Metakaoline is a relatively new pozzolanic additive, obtained by calcination of kaolin clay at relatively low temperatures. Themselves pozzolanic additives are known for a very long time. Currently, there is interest to pozzolanic materials again, because their usage allows reducing the total environmental impact and cost of cement. The influence of metakaoline on hydration and hardening of cement was studied. The usage of metakaoline as the additive to cement composition increases the strength of cement stone. Beside it improves the frost and corrosion resistance of cement stone reducing its porosity, which opens up new opportunities for use of additives based on metakaoline. Metakaoline allows to replace part of cement in the composition of cementitious materials, to produce high-quality dry mixes, mortar, concrete and others materials for example, plaster, putty, self-leveling compounds. The study the effect of metakaoline on the properties of tile adhesives showed the possibility to change their composition thanks the partial replacement of the polymer by metakaolin. Carried out research on the replace of polymer microfiber by metakaoline in repair dry mixes showed that it does not deteriorate their properties. Therefore, metakaoline can be used as an alternative to polymer fibers in the composition of repair mixtures. [ABSTRACT FROM AUTHOR]

A linear optimization method is applied to improve mechanical properties of fiber reinforced cement mortar. Since this method is preferably used in other scientific disciplines, few preconditions are taken into account in advance, in order to accommodate it to the specifics related to building materials design. Defining physical limitations and accelerating the optimization process, the target values of optimization are reached in 21 days after 3 optimization steps. Within this relatively short time span, the compressive and bending strengths of fiber reinforced cement mortar increase from 36.9 to 52.2 MPa and from 9.1 to 10.1 MPa, respectively, while identical components are used. The improvements are achieved after preparation of only nine different mixtures, which is a very small number confirming the effectivity of this method in the field of building materials design.

The main sources of dietary fiber in the diet of a modern person, along with grain product processing, are vegetables and fruits. Apple pomace is rich in dietary fiber. In the work, technological studies were carried out to identify the optimal amount of additives from apple pomace, substituting a part of minced meat, in order to enrich dishes with dietary fiber. We prepared the flour dish "Manty with meat" and "Cabbage rolls". Apple powder was added to minced meat in the amount of 5, 10 and 15%, reducing the amount of meat. In order to study the effect of apple powder additives on organoleptic indicators, nutritional and biological value, studies of the chemical and amino acid composition were carried out and chemical "Skor" of the studied and control samples. Studies have shown that the use of apple powders in manti fillings, in addition to minced meat, lead to an increase in the dry matter content in raw and prepared dishes by 5, 8 and 12%, respectively, compared with control (traditional) samples. In cabbage rolls with apple nutritional supplement fiber content increased by 6.2% compared to control sample. The effectiveness of the use of apple pomace in the organization of dietary nutrition was shown. [ABSTRACT FROM AUTHOR]

Two pairs of hollow fiber membrane modules used for water drinking treatment by ultrafiltration (outside-in permeate flow direction) were tested for assessing the efficiency of cleaning by physical methods. The two hollow fiber membranes were of polypropylene type, of different molecular weight cut-off (MWCO): 0.097 μm and 0.047 μm respectively. For each module pairs, there were provided same water flow rate and inside cylinder pressure. One of the hollow fiber membranes has been subjected to relaxation, backflushing procedure, and strong shear force, while for the other module, no treatment was provided for comparison reasons. All modules were horizontally positioned for the tests. The results highlight that for membranes of smaller MWCO, relaxation and backflush procedures were effective. For membranes of large MWCO, backflushing was effective, but poor results were registered for reversible fouling. Therefore, a reduced time interval between backwashing is needed, if one uses membranes at large MWCO. Using of small bubble jets at different velocities in order to enhance turbulent flow regime did not provide relevant results. A composite index is proposed, by computing the ratio of the inside cylinder pressures and the feed pump power consumption, at the same outlet flow rate. For membranes of smaller MWCO the index is greater that 1, indicating that inside cylinder pressure can be yet efficiently increased - ratio for increased pressure is higher that power consumption ratio.

The poly(vinylidene fluoride) (P(VDF)) fiber membranes were synthesized through electrospinning technique using P(VDF) in Dimethylformamide (DMF)/acetone mixtures of different weight ratios. Variation in the morphology of the membranes for different (DMF)/acetone ratios was analyzed with Atomic Force Microscopy (AFM) and 1:1 weight ratio was found to be optimum for obtaining smooth, uniform membrane. The alignment of the fibers under static and dynamic collectors was visualized from Scanning electron microscopy. Enhancem of β-phase was observed in the membrane collected from the dynamic collector and it was further verified through X-Ray diffraction and functional studies. The ferroelectric and piezoelectric properties of the membrane were confirmed with P-E loop and domain switching behavior respectively. [ABSTRACT FROM AUTHOR]

We report a study about the effect of the excitation polarization on the amplified spontaneous emission (ASE) in a rhodamine-6G-doped graded-index polymer optical fiber (POF) when the fiber is transversally pumped with respect to the symmetry axis. We show that both the threshold energy for ASE and the intensity of the emitted amplified radiation are dependent on the polarization of the excitation beam. The spectral characteristics of the ASE spectrum obtained for the two pump polarizations are compared. [ABSTRACT FROM AUTHOR]

Electrospun fiber mats have been used for the delivery of hydrophilic/hydrophobic drugs in drug delivery systems because they offer various properties such as high surface area/volume ratio, high porosity and high efficiency.1,2 In this study, the electrospun fibers were prepared by electrospinning polyethylene oxide (PEO), polymethylmethacrylate (PMMA) blended bis-chalcone derivatives ((2E,6E)?2,6?bis[(thiophen?2?yl)methylene]cyclohexanone and ((2E,6E)?2,6?bis(4-nitrobenzylidene)cyclohexanone), and streptomycin sulfate as the model drug. The fiber samples were characterized by scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEMEDX), Fourier transform infrared spectroscopy (FT-IR), and Thermal gravimetric analysis (TGA). In vitro release of drug from the drug-loaded fibers was studied in simulated physiological conditions by ultravioletvisible spectroscopy. Morphological analysis results revealed that the electrospun fibers prepared with the mixture of PMMA, PEO and ((2E,6E)?2,6?bis(4-nitrobenzylidene)cyclohexanone) with streptomycin sulfate had a more uniform, bead-free, and random morphology. According to the release studies, the highest amount of drug release was achieved for ((2E,6E)?2,6?bis(4-nitrobenzylidene)cyclohexanone) in the 240 minute period. These results showed that drug-loaded PMMA and PEO fiber mats can be used as drug delivery vehicles in drug delivery systems. [ABSTRACT FROM AUTHOR]

It has been proven by many researchers that the overall behavior of concrete can be improved by the addition of fibers. In the present investigation numerical (FEM) modeling of elastically plastic single straight fiber pull out of elastic matrix volume was realized. Comparison was done with steel fiber is pulling out of concrete matrix. Fiber pulling out micromechanics is governing the macro-crack opening process - fiberconcrete post cracking load bearing capacity is dependent on each single fiber pull out force. Numerical modeling was performed using 3D approach, which takes into account the non-linearity is presenting in physical model in combination with a finite element method (FEM). Straight shape fiber pulling out of concrete block in fiber direction was investigated earlier (Li et al., 1998; Mobasher et at., 1995). In our investigation numerical modeling was performed for straight shape fiber was embedded into elastic matrix under variable angle to applied pulling force and at variable depth.

In this study, author numerically proposed a high-birefringence and low-loss index-guiding photonic crystal fiber (PCF) and compare it with three other types of PCF. Four cases of PCFs are investigated by the finite element method. A high modal birefringence is obtained when the cladding is composed of elliptical air holes placed asymmetrically, with two half-size elliptical air holes on the top and bottom of the PCF core. The size control of these air holes is the key to reaching a high birefringence and a low confinement loss. Numerical results confirm that the proposed structure at an excitation wavelength ?= 1550 nm shows a birefringence of up to 2.085×10-2 and a confinement loss of less than 1.63×10-5 dB/km.

In this paper we present some recent work we performed on the socio-economic impact of fibre access networks (FTTH/FTTx). We summarise some results from a pre-study on the effects of fibre deployments in Sweden. Specifically, we list and quantify savings in data and telecommunications costs for Swedish local governments, estimate the added values for fibre-connected citizens, and present a multivariate regression analysis of the early impact on employment and population evolution, building on data from 290 municipalities between 2007 and 2010: we find a weak but statistically significant correlation, and we are able to exclude backward causality.

In this paper, we propose a low cost diagnostic system for dental therapy. This system is capable of carrying out real time observation inside the narrow root canals of oral cavity with high precision and without blind areas using a single graded-index image fiber (GRIN image fiber). The system uses the GRIN image fiber to irradiate the sample to be observed and return the sample image back to the CMOS image sensor of the microscope through the same image fiber, which is different from conventional system that uses separate fibers for illumination and observation. The results suggest that this device can illuminate and observe sample patterns of up to 10μm line and space widths with approximately the same quality as those illuminated by external light source. This precision is sufficient to detect cracks and collaterals of the root canals. [ABSTRACT FROM PUBLISHER]

This paper proposes an automatic measurement algorithm for calculating statistics of pulp fiber lengths and curvature. The fibers are extracted from digital images, and a parametric model is fit to the extracted objects. The modeling approach improves the robustness of the detection and enables connecting broken fiber parts into full length curves. The developed algorithm is compared to an alternative method, and concluded to yield similar results while providing additional features, such as curvature estimates, of the detected fibers.

It is known that dissipative solitons (DS) generated in fiber oscillators lose their stability at cavity lengthening. We report on the experimental realization of the DS oscillator with increased cavity length (L∼100 m). Stable operation is achieved in the all-fiber configuration consisting of a short single-mode-fiber (providing mode locking via nonlinear polarization evolution) and a long PM-fiber (providing formation of highly-chirped DSs) parts. We have identified the next limiting effect related to the onset of Raman conversion of the DS spectrum. The maximum output energy obtained with 5.5-µm-core PM-fiber amounts to ∼30 nJ in 30–70 ps pulses externally dechirped to 200–300 fs at repetition rate ≥1.7 MHz. At that, the Stokes pulse reaching comparable energy inside the cavity does not break the soliton stability, surprisingly. The obtained results are analyzed using a simple model. Higher DS energy is shown to be possible by means of a PM fiber core enlargement. [ABSTRACT FROM PUBLISHER]

We present a successful transmission of an IEEE 802.11n 2×2 Multiple Input — Multiple Output radio signal over standard graded index multimode fiber at several kilometers length. For the first time commercially available Access Points were used in the MIMO over multimode fiber experiment. Transmission was carried above the baseband of the multimode fiber (in passband), the electrical carrier was at 2.4 GHz. The experiment indicated an increase in the bitrates in the MIMO mode versus single channel operation. It has to be emphasized we have measured a real payload bitrate of the system.

A multiple wavelength Brillouin/erbium fiber laser that generated six output channels at maximum pumping powers is presented. The laser is configured to allow uni-directional flow of both the Brillouin pump and the Brillouin Stokes signals through the Erbium doped fiber amplifier. Stability studies on the generated channels buttressed the fact that the proposed laser has met the stringent requirement of power stability and precision channel spacing in order to be deployed to support the DWDM systems. At Brillouin pump power of 2 mW and 1480 nm laser pump power of 130 mW, the wavelength of the first channel has not shifted over an observation period of one hour. The other channels recorded average wavelength shifts of 0.002 nm. Over the same observation period, the first channel records a power fluctuations of only 0.03 dB. [ABSTRACT FROM PUBLISHER]

The present work is focused on study of “green composites” elaborated from thermoplastic starch (TPS) as polymer matrix and a fiber from natural origin (rush) as reinforced fiber. The effect of the fiber content has been studied by means of the mechanical properties.

However the biodegradability behavior of the resulting composite raise this composite as useful an industrial level. [ABSTRACT FROM AUTHOR]

Optical supercontinuum is typically produced by passing short light pulses through a piece of photonic crystal ‘holey’ fiber; by nonlinear interactions the spectrum is dramatically broadened. This has become an established method to provide broadband light as required for various applications. Here we report on a scheme which uses such a fiber in a resonator arrangement so that optical feedback will enhance the effect. This provides additional degrees of freedom for optimization, and it reduces power requirements. [ABSTRACT FROM AUTHOR]

By directly chemical oxidative polymerization of aniline on Au electrode treated with Au nanoparticles (Au-NPs) deposition and 4-aminothiophenol (ATP) modification, polyaniline (PANI) fibers were obtained in-situ in micro-/nano- size with two dimensional network structures. It was found that the ATP modification played an important role for the formation of fibrous network and in the decrease in the contact resistance between the PANI film and the electrode surface. The PANI film showed a rapid response upon the exposure to various gases with low detection limit, which indicated that the developed PANI sensor could be applied in the high sensitive detection of hazardous gases.

In this study, fibers were obtained by electrospinning technique to increase the bioavailability of biocompatible polymethyl methacrylate (PMMA)/polyethylene oxide (PEO)/bis-chalcone derivatives ((2E,6E)-2,6-bis(4-nitrobenzylidene)cyclohexanone and (2E,6E)-2,6-bis[(thiophen-2-yl)methylene]cyclohexanone) containing Streptomycin sulfate as a model drug in two different ratios (30 and 60 mg). The antibacterial effects of drug-containing and non-drug fibers against Bacillus cereus and Escherichia coli were investigated. As a result, it was observed that the drug-free fibers did not have any antibacterial effect, while the drug-containing fibers completely destroyed B. cereus and E. coli. Our findings can provide insight into new fibers prepared with antimicrobial compounds for wound dressing applications. [ABSTRACT FROM AUTHOR]

The study is concentrated on assessment on compressive strength of Waste Rubber Tube Tyre (WRTT) fiber as reinforced bar replacement in concrete. WRTT fiber is produced from waste tyre industry. WRTT fiber is determined for its density and percentage of water absorption. WRTT fiber is designed and cut to a size of 5 cm in length, 0.5cm in breadth and 0.1 cm in thickness. WRTT fiber is mixed with concrete with percentage proportion of 0 %, 1 %, 1.5 %, 2.0 % and 2.5 %. All concrete are cured in clean and clear water and tested for compressive strength at 7 and 28 days. Every mixes illustrateda low compressive strength compared to a control mix. The highest percentage proportion of 1.0 % showed 40–45 % different when compared with control mix for early and matured ages. Finally, further studies can be done to assess the general issues of strength to show the potential of WRTT fiber in concrete. [ABSTRACT FROM PUBLISHER]

By mixing with a certain amount of polypropylene or glass fiber, the usage quality of cement-stabilized macadam can be improved. In this passage, a large number of experiments with various kinds and contents of fiber were carried out. After comparing the experiment result of admixture of fiber cement-stabilized macadam, the unconfined compressive strength, splitting strength, compression modulus and other mechanical properties are researched. According to the above quantitative analysis, we got the conclusion that the mixing of fiber play a good rule in improving the usage quality of cement-stabilized macadam. Therefore, cement-stabilized macadam reinforced with fiber can be widely used in engineering later. [ABSTRACT FROM PUBLISHER]
