Opis:: Performance of cation and anion exchangers was evaluated by carrying out breakthrough analyses of pH, conductivity, free mineral acid (FMA) and various dissolved solids for an industrial water treatment plant of 700 gpm capacity. The breakthrough curves showed no leakage of calcium, magnesium and chloride throughout the operating period of the train, however, they indicated the early leakage of sodium, potassium, sulphate and silica. The operating/breakthrough capacity, total capacity and degree of column utilization were determined. The column utilization was found to be 67.85%, 38.93% and 16.78% against the design values of 90%, 85% and 85% for cation, primary and secondary anion exchangers respectively. The operating time of the water treatment train was significantly increased by achieving adequate capacity utilization of secondary anion exchanger. The low capacity utilization of secondary anion resin due to early silica slippage, has been discussed in the paper.

Opis:: With the rapid increase in transmission speeds of communication systems, the demand for very high-speed lowpower VLSI circuits is on the rise. Although the performance of CMOS technologies improves notably with scaling, conventional CMOS circuits cannot simultaneously satisfy the speed and power requirements of these applications. In this paper we survey the state of the art of on-chip interconnect techniques for improving performance, power and delay optimization and also comparative analysis of various techniques for high speed design have been discussed.

Opis:: Sodium alginate (TiO2) sand composites were prepared by solution casting. Purified sand was added in the composite films to increase electrical conductivity. Electrical properties such as conductivity, capacitance, dielectric constant, and loss tangent of the composites were investigated. The current voltage characteristics for all the composites showed ohmic behavior. All the electrical properties have been found to improve with the incorporation of sand (SiO2) but 6 % sand containing composite exhibits the best electrical properties. The mechanical properties tensile strength (TS), elongation at break (Eb) and Young modulus for 6 % sand containing composite film are found to be 4.445 MPa, 9.76 %, and 72.8 MPa respectively. The experimental results reveal that the blended films exhibit higher stability and improved mechanical properties of both tensile strength and elongation at break in dry state. Water absorption properties of the composites are found to decrease with the increase of sand content. Lowest water uptake properties and highest stability were demonstrated by 6 % sand containing sample. Electrically conductive composite films have useful applications for solar cells and optoelectronics. Thus, this study is very much expected to aid in the design and selection of proper composite for the potential application of solar cell and optoelectronics.

Opis:: Homogeneous Polyvinyl alcohol (PVA)/Carbon nanotube (CNT) composite has been prepared by solution casting method using gum acacia as a surfactant. CNT content in the composite was varied from 5-10 % by weight. The thermal properties of PVA/CNT composites were investigated by Thermo Gravimetric/Differential Thermal Analyzer (TG/DTA) and Thermo Mechanical Analyzer (TMA). TG/DTA results showed that higher thermal stability in higher percentage of CNT in the composites. The 10 % CNT containing PVA composite exhibit highest onset of melting, glass transition point and offset of melting temperature and the recoded values are 330.4K, 379K and 421.3K respectively. All of the result indicates that the developed PVA/CNT composite might be promising for use in solar cell application.

Opis:: The aim of this study was to determine the concentration of Fe, Ni, Cu, Zn and Pb in scalp hair of leukaemia patients and healthy volunteers, using the optimised XRF method. Leukaemia hair samples were classifi ed corresponding to type, growth and age of the participants. The results showed that the studied trace elements (TEs) in both of leukaemia and control groups were positively skewed. In comparison with the control group, lower Fe, Cu, Zn and Pb and higher of Ni medians were found in all studied leukaemia patients. The median rank obtained by Mann–Whitney U-test revealed insignifi cant differences between the leukaemia patients subgroups and the controls. An exact probability (α < 0.05) associated with the U-test showed signifi cant differences between medians in leukaemia patients and controls groups for Pb (lymphatic/control, acute/control), Cu (lymphatic/control, chronic/control), Ni (lymphatic/control, chronic/control) and Fe (chronic/control). Very strong positive and negative correlations (r > 0.70) in the scalp hair of control group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn, Pb/Fe-Pb, Cu/Ni-Zn/Ni, Cu/Ni-Pb/Ni, Zn/Ni-Pb/Ni, Zn/Fe-Zn/Cu, Pb/Ni-Ni and Ni/Fe-Pb/Ni, whereas only very strong positive ratios in the scalp hair of leukaemia patients group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn and Pb/Fe-Pb, all correlations were signifi cant at p < 0.05. Other strong and signifi cant correlations were also observed in scalp hair of both groups. Signifi cant differences between grouping of studied TEs in all classifi ed leukaemia groups and controls were found using principal component analysis (PCA). The results of PCA confi rmed that the type and the growth of leukaemia factors were more important in element loading than the age factor.

Opis:: The most desired journey by human being is definitely travel through time. For centuries, people dream about time travel, to be able to go back and fix mistakes of the past. But there are many complications associated with time travel - starting from technological aspects ending with the philosophical paradoxes. Yet, is time travel possible from the technological and philosophical perspectives? How to solve the paradoxes of time travel? It should be noted that realisation of time travel leads not only to the discovery of the nature of time, but also to the understanding how much is unknown about it. In this paper, probability of time travel and solutions to paradoxes will be critically analysed from philosophical perspectives.

Opis:: For the manufacturing of load-bearing carbon fibre reinforced plastics (CFRP) made from staple carbon fibres (CF) , statements of the CF fibre length in the composite are essential. However, no suitable fibre length measuring method is currently available for long staple CF over 60 mm. The aim of this study is the development of an effective method for characterization of the fibre length distribution of long staple CF. For this method, a fibre beard specimen is extracted from a sliver manufactured from 80 mm staple CF, which is then scanned. Greyscale values densities (GD) of the individual length classes are determined from the scanned images, which correspond to the number of fibres per length class. From the proportion of all length classes, a span length diagram and staple fibre length diagram can be compiled. The results show the good potential of the method developed for the fibre length measurement of long staple CF.
Dla wytwarzania kompozytów ze wzmocnieniem włókien węglowych bardzo ważna jest znajomość rozkładu długości tych włókien. Niestety, jak dotychczas nie istniały odpowiednie metody pomiarowe pozwalające charakteryzować włókna odcinkowe o długościach powyżej 60 mm. Celem pracy była analiza istniejących metod pomiarowych oraz opracowanie metody, która umożliwiłaby satysfakcjonujące rozwiązanie tego zagadnienia. Zostały przedstawione zasady działania tej metody oraz uzyskana dokładność pomiarów.

Opis:: The aim of this paper was to investigate the effect of carbon fibre (CF) length and preparation prior to carding on the mechanical properties of hybrid yarns as well as composites consisting of CF and polyamide 6 (PA 6). The hybrid yarns are manufactured using an optimised process route of carding and drawing with a flyer machine from virgin staple CF (40/60/80/100 mm) and PA 6. In order to explore the effect of fibre preparation on the mechanical properties of hybrid yarns as well as composites, virgin staple CF and PA 6 fibres were prepared by varying the mixing type prior to the carding process. For this purpose, the fibres were mixed either by a fibre-opening device or supplied directly to the carding machine without prior mixing. The CF content of the card webs produced is kept at 50 volume %. Hybrid yarns were produced with a twist of 102 twist/m and then thermoplastic uni-directional (UD) composites were manufactured from them. The investigations revealed the influence of the input CF length and mixing type on the mechanical properties of hybrid yarns and thermoplastic UD composites.
Celem badań było stwierdzenie wpływu długości włókien węglowych i ich obróbki przed zgrzebleniem na mechaniczne właściwości przędz hybrydowych/włókno węglowe /poliamid 6/ jak również kompozytów z nich wykonanych. Zmieniano skład mieszanki przed zgrzebleniem. Włókna mieszano lub dostarczano bezpośrednio do zgrzeblenia. Zastosowano zoptymalizowany proces zgrzeblenia i rozciągania z użyciem niedoprzędzarki. Przędze hybrydowe posiadały skręt 102 skręty/m. Z przędz hybrydowych produkowano termoplastyczne kompozyty „jednokierunkowe”. Badania wykazały wpływ parametrów wejściowych na końcowe właściwości kompozytów.

Opis:: The most common measuring method to characterise the dynamic yarn path in the ring spinning process is to measure the yarn tension, where the yarn path is almost straight. However, it is much more complex to measure the yarn tension at the other positions, for example, between the yarn guide and traveller (balloon zone) and between the traveller and winding point of the cop (winding zone), as the yarn rotates continuously around the spindle axis. In this paper, two new methods of yarn tension measurement in the balloon zone are proposed. In the first method, the balloon shape was first recorded with a high speed camera. The balloon tension was then calculated by comparing the yarn strain (occurring in the balloon zone) measured by a digital image analysis program with the stress-strain curve of the yarn produced. In the second method, the radial forces of the rotating balloon were measured by using modified measurement techniques for measurement of yarn tension. Moreover a customised sensor was developed to measure the winding tension between the traveller and cop. The values measured were validated with a theoretical model and a good correlation between the measured and theoretical values could be revealed.
Najczęściej stosowaną metodą pomiarową dla scharakteryzowania dynamiki przędzy podczas przędzenia obrączkowego jest pomiar naprężenia przędzy w miejscu gdzie jej przebieg jest prawie prostoliniowy. Jednakże znacznie bardziej skomplikowany jest pomiar naprężenia przędzy pomiędzy prowadnikiem i biegaczem (strefa balonu) oraz pomiędzy biegaczem i punktem skręcania przed cewką nawojowa (strefa skręcania) ponieważ przędza wiruje w sposób ciągły wokół osi wrzeciona. W pracy przedstawiono dwie nowe metody pomiaru naprężenia przędzy w strefie balonu. W pierwszej wstępnie określano kształt balonu za pomocą kamery o dużej prędkości powtarzania. Następnie określano naprężenie balonu przez porównanie odkształceń przędzy powstających w strefie balonu a mierzonych za pomocą cyfrowej analizy obrazu i programu wykorzystującego krzywą zależności naprężenie-odkształcenie produkowanej przędzy. W drugiej metodzie promieniowe siły wirującego balonu były mierzone przy zastosowaniu zmodernizowanej techniki pomiaru naprężenia przędzy. Pomierzone wartości były porównywane z wartościami modelu teoretycznego przy czym stwierdzono istnienie bardzo dobrej korelacji.

The fundamental forces broke their symmetries, making impossible to unify them together. Nevertheless, the symmetry of the Universe has not changed and interestingly will never. By analysing global and local symmetry, this paper will present a hypothesis on the future shape and energy expansion of the Universe. A new theory of point symmetry of the Universe will also be introduced.

Opis:: The aim of this paper is to describe a split S-shaped composite meta atom which shows double negative characteristics at resonance frequency. The proposed meta-atom structure exhibits an almost 3.70 GHz bandwidth when the operating frequency from 8 to 14 GHz (X-band). In this study, the ring width, split width, size of substrate material, and the substrate material itself are varying to investigate their effect on the resonance frequencies. Metal strips of the outer resonator are the splits and the inner ring resonator is designed in a way that it forms a split S-shaped structure on the epoxy resin fibre (FR-4) substrate material. The CST Microwave Studio electromagnetic simulator software was used for the design and simulation purposes, and an Agilent N5227A vector network analyser was used for practical measurements.

Opis:: Biodiesel is well known substitute fuel for combustion ignition engines. It can diminish the various harmful emissions like carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM) emissions; however it holds some draw back that includes increase in nitrogen oxides (NOX) emission as compared with diesel fuel. The present work demonstrates the comparative study of exhaust emissions of a 4-stroke naturally aspirated variable compression ratio compression ignition engine utilizing biodiesel made from linseed oil and sesame oil. Various results of exhaust emissions are obtained through exhaustive experiments at compression ratio 17 and 18. Study showed that the linseed oil displayed the improved emission results in HC emissions and CO emissions whereas blend of isopropyl alcohol and diethyl ether displayed the better emissions of CO2 and NOX and standard diesel as well.
