LABORATORY DETERMINING OF SOIL STRENGTH PARAMETERS IN CALCAREOUS SOILS AND THEIR EFFECT ON CHISELING DRAFT PREDICTION

This study was conducted to determine the effect of soil strength parameters; ploughing depth and rake angle on chiseling force when ploughing with 7 narrow blade chisel plough in calcareous soils. Laboratory experiments were achieved by using direct shear device on the soil at moisture content of 12, 16, 20 and 28 % d.b. and bulk density of 1.4, 1.5 and 1.6 g/cm. Linear regression equations were found to explain the relation between soil strength parameters and both soil moisture content and soil bulk density. The obtained equations of main soil strength parameters i.e. angle of internal friction of soil (Φ-degrees) and soil cohesion (Cg/cm) were applied to fined the actual general soil strength parameters at the actual conditions when ploughing at different levels of depth (12.2, 17.3 and 22.17 cm). The actual main soil strength parameters were found out at the soil moisture content of 21.51, 22.72 and 24.64% d.b. and soil bulk density of 1.4, 1.5 and 1.6 g/cm which were determined at the previous actual ploughing depths. The statistical linear regression analysis of the laboratory experimental data and the obtained linear regression equations appeared that each of soil adhesion, soil metal friction angle, angle of internal friction of soil and soil cohesion were inversely proportional to soil moisture content and were directly proportional to soil bulk density. In the same time, the soil shear plan had a contrary manner when affected by both soil moisture content and bulk density. The field experimental data were subjected to the analysis of variance (ANOVA) and all treatments were compared using the least significant difference method (L.S.D.) at 5% probability level. The analysis revealed a significant relationship between tillage depth, rake angle and their interaction and the net pulling force. The minimum pulling force (5.38-5.72 KN/7blades) was occurred at tillage depth of 15 cm and a range of rake angle from 16 to 22. Also, a linear regression equation was drawn out to predict the net pulling force of a 7 narrow blades chisel plough when ploughing in calcareous soils (Maryut area). The predicted force was affected by soil strength parameters, ploughing depth and rake angle, 3.4km/h ploughing speed and at the levels explained before
1 EMBODIED COGNITION , ORGANIZATION AND INNOVATION

This chapter explains and employs a constructivist, interactionist theory of knowledge that has come to be known as the perspective of ‘embodied cognition’. That view has roots in earlier developmental psychology, and in sociology, and more recently has received further substance from neural science. It yields a basis for a cognitive theory of the firm, with the notion of cognitive distance between people, the resulting view of organization as a cognitive focusing device, the need for external relations with other organizations to compensate for organizational myopia, and the notion of optimal cognitive distance between firms for innovation by interaction.

Student ’ s Perspective of eLearning and the Future of Education with MOOCs

The number of students enrolling in e-Learning courses at institutions is increasing exponentially. One would hardly ever find a course of study in an institution that has not blended Information Communications Technology (ICT) or Electronic and Web based resources in some form or the other. Institutions offering Massive Open Online Courses (MOOCs) are claiming millions of students enrolled in their courses. One institution claimed to have at least onestudent enrolled from every country in the world. Students are the main stakeholders in e-Learning courses. Students were asked about their perceptions of e-Learning courses in an effort to improve its delivery and student success. Problems with technology are the main reason that student’s dropout from e-Learning courses. Research shows that novice e-Learner’s underestimate the amount of ICT skills that are required for success. The researchers used a mix of research design methods andcollected qualitative data to triangulate with quantitative data from 185 participants. The research hypotheses were then tested by applying the results to the Decomposed Theory of Planned Behaviour (DTPB) model to further inform the findings. Resultsindicate that the ease of use and its perceived usefulness creates a positive attitude towards eLearning and further reinforces student’s intention to continue. The teachers have a strong influence on students to use e-Learning and so do their peers. Most students are quite confident with using e-Learning platforms (32% of them were IT students). However, the rest are not happy with the resources and technologies of their current e-Learning platforms. The researchers conclude that the e-Learning platform at the institution of study needs immediateattention to attract and retain more students. This study has implications for the institution and every other institution that intends to provide more eLearning courses and possibly follow the MOOCs development pathway and offer MOOCs courses.

Redescription of Chelifer eucarpus DALMAN ( Arachnida , Chelonethi , Withiidae ) and fi rst records of pseudoscorpions in copal from Madagascar and Colombia

Chelifer eucarpus DALMAN, 1826, which was previously considered a nomen dubium, is redescribed from the holotype tritonymph and transferred to the genus Withius KEW, 1911 (Withiidae). The provenance of the fossil is unknown, but it is most likely to be of East African origin (Zanzibar copal). Eucarpus HAGEN, 1870 is a generic nomen nudum, based on a misinterpretation of the binomen Chelifer eucarpus. The fi rst pseudoscorpions from Madagascan copal are recorded: a male and female of the genus Tyrannochthonius CHAMBERLIN, 1929 (Chthoniidae), and the deutonymphal exuviae of an unidentifi ed genus of Atemninae (Atemnidae). The fi rst pseudoscorpions from Colombian copal are recorded: a female of Paratemnoides nidifi cator (BALZAN, 1888) (Atemnidae) and an adult of Pachychernes aff. subrobustus (BALZAN, 1892) (Chernetidae) (fi rst record of the genus Pachychernes from Colombia).

Z u s a m m e n f a s s u n g Chelifer eucarpus DALMAN, 1826, bisher als ein nomen dubium betrachte, wird anhand des Holotypus, einer Tritonymphe, neu beschrieben und der Gattung Withius KEW, 1911 (Withiidae) zugeordnet. Die Herkunft des Fossils ist unbekannt, aber sehr wahrscheinlich stammt es aus Ostafrika (Sansibar-Kopal). Die Gattung Eucarpus HAGEN, 1870 ist ein nomen nudum, basierend auf einer Fehlinterpretation des Binomens Chelifer eucarpus. Die ersten Pseudoskorpione aus dem Madagaskar-Kopal werden beschrieben: ein Männchen und ein Weibchen der Gattung Tyrannochthonius CHAMBERLIN, 1929 (Chthoniidae) und die Exuvie einer Deuteronymhe einer unbestimmten Gattung aus der Unterfamilie Atemninae (Atemnidae). Ferner werden auch aus dem Kolumbianischen Kopal die ersten Pseudoskorpione beschrieben: ein Weibchen von Paratemnoides nidifi cator (BALZAN, 1888) (Atemnidae) und ein adultes Exemplar von Pachychernes aff. subrobustus (BALZAN, 1892) (Chernetidae) (der erste Nachweis der Gattung Pachychernes aus Kolumbien).
QUANTITATIVE VISUALISATION OF PULP REFINING IN A PRODUCTION LINE REFINER

In this work pulp flow in a production-line first-stage TMP-refiner operating at 10 MW has been visualised using multipulse stroboscope, endoscope optics, specialised illumination system and a CCD camera. Measurements have been performed at different radial locations and with different refiner operation parameters. The parameters measured from the plate gap were pulp velocity (magnitude and direction), pulp orientation, percentage area covered with pulp and the presence of fibre flocs .
Laminar Burning Velocities in Stoichiometric Hydrogen and Hydrogen-Hydrocarbon Gas Mixtures

Measurements of the laminar burning velocities of hydrogen, acetylene, propane, and methane have been made using a spherical combustion bomb. In addition measurements were also made for mixtures of hydrogen with acetylene, propane, methane, and simulated combustion products in various proportions. All mixtures were stoichiometric with air and pressures and temperatures ranged from 0.5 to 7 atm and 300 to 550K, respectively. The values for the pure gases were in good agreement with previous experimental results from combustion bombs and in reasonable agreement with theoretical calculations by Warnatz. When mixed with hydrogen, propane and methane exhibited a double peak behavior in the burning velocity, as a function of pressure along an unburned gas isentrope.
Multivariate curve resolution methods and the design of experiments

A major problem of multivariate curve resolution methods is the underlying non‐uniqueness of the pure component decompositions. This raises the question how a chemical experiment should be designed so that the solution ambiguity is as small as possible. Changes of the reaction conditions belong to the possible variations whereas for a fixed chemical reaction system, the pure component spectra appear to be unchangeable.
Population Density of Root Knot Nematode , Meloidogyne incognita Infecting Date Palm under Stress of Aqueous Extracts of Some Botanicals and a Commercial Bacterial Byproduct

Under screen house conditions, certain plant aqueous extracts were added to pots planted with date palm cv. Sewi inoculated with root knot nematode Meloidogyne incognita. These plants, Hyphaene thebaica as mashed fruit pomace, Punica granatum as mashed fruit peel, Stevia rebndiana as mashed dry leaves, and Moringa oleifera as mashed dry leaves were used as 5% concentration at the rate of 30 ml per pot and the commercial byproduct, micronema (containing strains of Serratia sp., Pseudomonas sp., Azotobacter sp., Bacillus circulans and B. thuringiensis) was used at the rate of 0.5 ml/pot. The influence of the tested botanical aqueous extracts and the commercial product on root knot nematode was shown as evidenced by the percentages reduction of number of galls, eggmasses and hatched juveniles on roots of date palm seedlings. Also, plant growth criteria were enhanced at different degrees.

A Proposed Sequence-to-Sequence Modeling for Arabic Dialect Machine Translation Dialect Arabic ( DA ) to English Translator

Neural machine is considered as an innovative approach to translate and make statistical machine model for translation that rely only on neural networks. The basic translation models using neural machine often contain encoder and decoder operations. The encoder makes cuttings a fixed-length sentence representation from a variable-length sentence that are input for translation, but the decoder produces right translation for this fixed-length representation. This paper motivates to compare between recurrent neural traditional networks that are recursive based (RNN), enhanced once long short-term memory unit (LSTM) and sub type of LSTM that are gated recurrent unit (GRU). The process sequence-to-sequence labeling check recurrent unit types to make translating between language pairs, for our study from Arabic Levantine to English. The perplexity measure is used to score the effect the trained model. BLEU scores is used to measure the quality of the translation.

Algal community diversity in relation to water source in an alpine stream

Aquatic ecosystems are often used to evaluate climate and land use change. However, these ecosystems are frequently sensitive to minute changes in water source. In this study the influence of groundwater on the benthic algal community within a single stream reach of Opabin Creek, British Columbia, was examined. Diatom diversity declined downstream of lower-temperature, higher electrical conductivity groundwater. Across the stream, a distance of several metres, mixing of groundwater was mirrored by gradations in algal communities. RÉSUMÉ L'utilisation des écosystèmes aquatiques dans les lignes de partage alpestres pour évaluer les changements dans le climat et l'utilisation de la terre exige un compréhension amélioré de leurs sensibilités aux facteurs tels que la source et les voies d'eau. Dans cette étude, l'influence de la décharge d'eaux souterraines sur la communauté d'algues benthique dans un section simple du ruisseau Opabin, en Colombie Britannique, a été examinée. La diversité de diatomée a diminué en aval de la décharge des eaux souterraines avec une plus basse température et une conductivité électrique plus élevée. À travers le ruisseau, une distance de plusieurs mètres, un gradient dans les propriétés de l'eau à cause du mélange des eaux souterraines a été reflétée par une gradation dans la communauté d'algues.
A shock tube laser schlieren study of cyclopentane ring opening

The pyrolysis of cyclopentane, 0.5% dilute in krypton, was investigated in a diaphragmless shock tube (DFST) using laser schlieren densitometry (LS). Experiments were performed at 148±5 Torr over the temperature range of 1620-2055 K. Fitting to density gradient profiles obtained from the LS experiments provide rates for the initial step for cyclopentane to ring open to 1-pentene. 1-Pentene then quickly dissociates to allyl and ethyl radicals. The ethyl product undergoes a fast and well understood dissociation to yield a hydrogen atom. The ring opening step is compared to other cycloalkanes. Further, in these LS experiments dissociation of the allyl radical is noncompetitive with H abstraction, so the studies can yield information regarding the reaction of allyl radicals and H-atoms. Rate coefficients from RRKM modeling for ring opening were found to give a rate of k150Torr = (3.614± 0.72) 10 71 T -15.9 exp(-60300/T) s -1 .
ffi cient Source Location Privacy Protection Algorithm Based on Circular Trap for Wireless Sensor Networks

With the aim of addressing the problem of high overhead and unstable performance of the existing Source Location Privacy (SLP) protection algorithms, this paper proposes an efficient algorithm based on Circular Trap (CT) which integrates the routing layer and MAC layer protocol to provide SLP protection for WSNs. This algorithm allocates time slots for each node in the network by using Time Division Multiple Access (TDMA) technology, so that data loss caused by channel collisions can be avoided. At the same time, a circular trap route is formed to induce an attacker to first detect the packets from the nodes on the circular route, thereby moving away from the real route and protecting the SLP. The experimental results demonstrate that the CT algorithm can prevent the attacker from tracking the source location by 20% to 50% compared to the existing cross-layer SLP-aware algorithm.
Prediction of Bursa Malaysia Stock Index using Autoregressive Integrated Moving Average and Artificial Neural Network

The FTSE Bursa Malaysia Kuala Lumpur Composite Index (KLCI) comprises the 30 largest listed companies is often used as the benchmark for the overall market performance of Malaysian stocks. Despite claims that the stock market is in fact an efficient market that follows a random walk process and therefore, is not predictable, there are evidences from previous empirical studies that argued that the stock market can be predictable. This study basically examines the ability of time series analysis and artificial intelligence system to predict the movement of stock prices. We use daily historical data from 3 January 2012 to 31 March 2014 as the base, whereas the daily forecasts will be generated for the period starting from 1 April 2014 to 31 March 2015 using Eviews 7 and MATLAB 8.5 with Neural Network Toolbox version 8.3. The predictability of the stock market is conducted using two different approaches of stochastic time series analysis and artificial intelligence system, namely the Autoregressive Integrated Moving Average (ARIMA) and Artificial Neural Network (ANN) methods, respectively. The findings revealed that the ANN (5-6-1) model outperformed the ARIMA (1,1,0) model with the lowest error recorded. Thus, it is concluded that the ANN model is indeed a more superior forecasting model as compared to the ARIMA model in forecasting the stock price index. Investors and financial analysts would be able to adopt the best technique to forecast accurately and gain insights to the Malaysian stock market. The knowledge and skill gained in performing forecasts using the right technique would definitely give the users an added advantage, as they would be able to get more accurate forecasts, thus, making better decisions in terms of risk and investment management.
Application Of Luffa Aegyptiaca Seed Oil In The Synthesis Of An Oil Modified Alkyd Resin

Natural oils are derived from vegetable’s oils such as linseed oil, Soya bean oil, Tung oil, dehydrated castor oil, fish oil, casein; and animal fats using several methods [10]. Most natural oils qualify as bio-based products as defined by the United States Secretary of Agriculture in ‘farm security and Rural Investment Acts’ (2002). There are limited numbers of naturally occurring vegetable oils (triglycerides). Chemically these are glycerides (esters) of unsaturated organic higher fatty acids like oleic, linoleic, linolenic and ricinoleic acids with alcohols. The properties of an oil depend on the proportion of these different long chain fatty acid radicals in the molecule [10]. Among these oils, castor oil is the only commercially available natural oil that is produced directly from a plant source. Other natural oil sources require chemical modification of the oils available from plants before use [4]. The ultimate use of natural oils is in the production of polymeric materials which are used industrially for different applications especially in the paint and coating industries [24]. For example, natural oil binders are used as bio-resins for vehicle or binders in the formulation of surface coatings in paint manufacturing industries [10]. A binder (vehicle) is a film-forming oil, to which other liquids are added. These liquids are diluents or thinners which are generally volatile liquids like mineral turpentine or organic solvents like xylol or acetone [17]. However, the diluents are Abstract: In this study, alcoholysis-polyesterification method was used to investigate the utilization of Luffa aegyptiaca seed oil in the synthesis of an oil-modified alkyd resin. The extracted oil seed gave an oil yield of 43.2% (w/w) and the physico-chemical characterization of the oil indicated it is a semi-drying oil with iodine value of 132.28 g I2 100 g1. Three grades of alkyd resins were formulated at 40% (I), 50% (II) and 60% (III) oil lengths (concentrations) respectively. The progress of the reaction was monitored by determining the acid value from the aliquots taken from the reaction mixture at various time intervals. The extent of reaction (%Pav) determined at the initial stage of the reaction ranged from 64.52 to 78.60%, indicating an encouraging degree of conversion. The corresponding average degree of polymerization (Dp) ranged from 2.7 to 4.7 which indicated the formation of high molecular weight alkyd resin. Physicochemical characterization of the synthesized Luffa aegyptiaca seed oil-modified alkyd resin (LASOMAR) gave iodine value of 72.1 ± 0.74, 78.1 ± 1.05 and 83.2 ± 1.0 g I2 100 g -1 for samples I, II and III respectively. The corresponding saponification values were found to be 205.2, 295.8 and 332.5 mg KOH g -1 . Samples I and II of the Luffa aegyptiaca seed oil-modified alkyd resin (i.e. 40% and 50% oil length) were resistant to Brine and Water with little resistance to Alkali.
TOPOLOGICAL COLD ATOM MODELS IN OPTICAL LATTICES

The aim of this thesis is the investigation of a few theoretical propositions of realizing various interesting topological states of matter using cold atomic systems. The topological order in quantum mechanics has been given much attention in the recent years as this concept, previously known mostly om the observation of the actional quantum Hall effect, has been generalized for a broader range of physical systems, where it can manifest itself in the form of non-local topological invariants. The search for new topological models and their implementations is undertaken not only because it is an exciting opportunity to study unique quantum mechanical effects, but also because they may be useful in some emerging technologies, such as quantum computing. Optical lattices are naturally a popular choice for such considerations due to an ease with which they can be modified and fine-tuned. The present thesis fits in this general scheme, as it focuses on a proper numerical evaluation of selected topological lattice models, paying great attention to their experimental feasibility. In a natural way the results presented here are related to other, earlier works. A er Chapter 1 containing preliminaries introducing the reader into specific features of cold atom settings and the topological order, in consecutive chapters we give a short summary of the main results published in 3 research articles forming the main part of the thesis. Chapter 2 discusses a realization of the emergent Rice-Mele model in a one-dimensional optical lattice. This paradigmatic model has already been realized experimentally in I. Bloch group using different techniques. On the other hand, the proposition we consider benefits om the ease of formation of defects, which is a consequence of its emergent nature. Moving on to systems with interactions, Chapter 3 focuses on the one-dimensional extended Bose-Hubbard model for filling ν = 3/2 and U = 2V, which for zero tunneling corresponds to the thin-torus limit of the topological system. We investigate whether this equivalence is still valid for non-negligible tunneling and take a closer look at the quantum phase transition in the system. Chapter 4 contains the analysis of the extended Bose-Hubbard model in the context of an experimentally plausible realization in a one-dimensional optical lattice of dipolar particles, with the emphasis on the topological Haldane insulator phase and on the pair-superfluid phenomena that arise as an effect of long-range interactions. The two appendices are technical and describe shortly the numerical tools used, namely the exact diagonalization and the density matrix renormalization group. Here the aim is to provide some useful, in the author’s opinion, hints for the interested reader rather than a precise introduction to the techniques which are more comprehensively discussed already in the references given.
