    The Lawrencian becoming of Deleuze

    Get PDF
    Gilles Deleuze and D.H. Lawrence, the philosopher with a poetic writing and the literary man with a philosophical project, invite us to consider their affinities and differences. An unavoidable trace of the Lawrence in Deleuze has not received the attention it should. This lack of critical attention makes the enterprise more worthy of initiation. To demonstrate something of the relationship between them, this essay is divided into three parts that gloss their main points of intersection and difference. I begin with the question of what is at stake in such a comparative endeavor. In the second section, I focus on the problem of subjectivity in Lawrence, and compare Lawrencian selves in such novels as The Rainbow and Women in Love to the fluid subjectivity associated with some Deleuzian concepts. Lastly, I consider how Deleuze\u27s concept of the assemblage is at work in Lawrence\u27s stories of different sorts of subjectivities that combine

    In this paper, we propose a five-step approach to detect obfuscated malware by investigating the structural and behavioural features of API calls. We have developed a fully automated system to disassemble and extract API call features effectively from executables. Using n-gram statistical analysis of binary content, we are able to classify if an executable file is malicious or benign. Our experimental results with a dataset of 242 malwares and 72 benign files have shown a promising accuracy of 96.5% for the unigram model. We also provide a preliminary analysis by our approach using support vector machine (SVM) and by varying n-values from 1 to 5, we have analysed the performance that include accuracy, false positives and false negatives. By applying SVM, we propose to train the classifier and derive an optimum n-gram model for detecting both known and unknown malware efficiently

    This work concerns the investigation of ion transport behaviour of NaI containing lithium tungsten phosphate glasses in order to understand better the role of NaI in the ionic cation transport. Glasses obtained in the system 0.5[x(2NaI)-(1-x)Li2O]-0.5[0.25(WO3)2-0.75P2O5] were investigated. The glass samples have been characterised using powder X-ray diffraction (XRD), thermal analysis, density and impedance spectroscopy. X-ray diffraction and thermal studies have confirmed that these glasses can be formed in the range x = 0 to 1. The mixed alkali glasses have shown higher activation energies and lower conductivities compared to single alkali doped glasses and this has been attributed to a mixed alkali effect.This work concerns the investigation of ion transport behaviour of NaI containing lithium tungsten phosphate glasses in order to understand better the role of NaI in the ionic cation transport.

    Evaluating the Impact of Material Selections, Mixing Techniques, and On-site Practices on Performance of Concrete Mixtures

    This paper aims to evaluate the influence of sand quality, water-to-cement ratio, binder properties, mix design methods, and mixing techniques on the fresh and hardened properties of concrete. The physicochemical characteristics of coarse aggregates, sands, and binders were analyzed. The experimental results show that the binders and coarse aggregates met standard specifications. However, none of the sands meet construction standards. Corrections were necessary for the dune sands to meet construction standards in terms of grain size distribution and fineness modulus. The results also show that the concretes formulated using the Dreux-Gorisse method exhibited higher quality than the locally formulated concretes. Furthermore, it was found that hand mixing resulted in inadequate mixing, material wastage, lower strength, and increased porosity, whereas machine mixing produced concretes with a more homogeneous microstructure, uniform particle distribution, lower porosity, and higher strength. The batch variability and compressive strength of the hand-mixed concretes were also found to be influenced by the expertise level of the batch mixer and the number of successive hand batches. It was also found that both the soluble silica and the inert methods are reliable for determining binder content in machine-mixed concrete. However, the soluble silica method occasionally exhibited significant variations in hand-mixed concrete compared to the inert method. A combined approach utilizing the average of both methods enhances the overall reliability of the binder content values. Observations on construction sites revealed widespread deviations from recommended guidelines. Issues such as lack of material inspection, proper stockpiling, ingredient contamination, and inadequate batch mixing contributed to variations in concrete workability, porosity, and compressive strength. Doi: 10.28991/CEJ-2024-010-02-016 Full Text: PD

    The level of environmental awareness among sixth graders’ students in light of some variables Preliminary study in the basic education schools Lattakia City

      The aim of the research was to investigate the level of environmental awareness among sixth graders’ students in light of the gender variables and the cultural level of the mother. In order to achieve this goal, the descriptive approach was used, and the "environmental awareness" scale was prepared. After verifying its validity, it was distributed to a sample of 140 students and students from the sixth grade school in Lattakia in 2017/2018. The results showed that the level of awareness among the sixth grade students was average. There were no statistically significant differences among the sixth grade in terms of environmental awareness due to sex, while there were statistically significant differences due to the cultural level of the mother in favor of students whose mothers have university degrees

    Challenges and Strategies of High-Capacity Transition Metal Oxides as Anodes for Lithium-Ion Batteries (LIBs)

    Get PDF
    To satisfy the growing demand for high-energy and high-power-densities Lithium-ion Batteries (LIBs), the design and development of efficient electrode materials are necessary. In comparison to graphite, transition metal oxides (TMOs) have recently been widely investigated as anode materials due to their promising properties. These combine high specific capacities and high working potential, making them attractive anode candidates for emergent applications. Unfortunately, because of their poor electronic conductivity and high-volume expansion during cycling, they are unpractical and difficult to employ. To overcome these limitations, different approaches have been adopted. Examples are synthesizing the metal oxides at the nanometric scale, designing three-dimensional or hollow structures, coating the material with carbonaceous materials, etc. In this chapter, we report the elaboration of nanostructured transition metal oxides (Co3O4, Mn3O4, Co3−xMnxO4) using alginate gelling synthesis method. The Co3O4 octahedral-like nanoparticles display a remarkable cycling performance and good rate capability of 1194 mAh g−1 at C/5 and 937 mAh g−1 at 2C. Partially substituting the Co with Mn was shown to result in the production of Co2.53Mn0.47O4 and MnCo2O4 with high initial specific discharge capacities of 1228/921 and 1290/954 mAh g−1, respectively. As a Co-free material, the Mn3O4 delivers a reversible capacity of 271 mAh g−1, after 100 cycles

    Penta­ammonium hepta­sodium bis­[penta­kis(μ2-oxido)deca­oxido­bis­(μ5-phosphato)penta­molybdenum(VI)] henicosa­hydrate

    The title compound, (NH4)5Na7[Mo5P2O23]2·21H2O, was prepared under atmospheric conditions in aqueous solution at room temperature. The structure contains the [Mo5P2O23]6− heteropolyoxometallate anion, which has been previously reported a number of times with a variety of differing counter-cations. Each anion is built up of five MoO6 octa­hedra sharing an edge and forming a ring which is closed by common corners of the terminal octa­hedra. The rings are closed on both sides by two asymmetric PO4 tetra­hedra, sharing three corners with three MoO6 octa­hedra. The anions are chiral and the two independent anions in the asymmetric unit were arbitarily chosen with the same chirality, but the centrosymmetric crystal contains both enanti­omers. The structure can alternatively be described as a succession of layers parallel to (101), formed by the [Mo5P2O23]6− anions and linked by sodium chains. Water mol­ecules and ammonium ions fill the remaining space and ensure the cohesion through extensive N—H⋯O and O—H⋯O hydrogen bonding

    Structural, Elastic, Electronic and Optical Properties of a New Layered-Ternary Ta4SiC3 Compound

    We propose a new layered-ternary Ta4SiC3 with two different stacking sequences ({\alpha}- and {\beta}-phases) of the metal atoms along c axis and study their structural stability. The mechanical, electronic and optical properties are then calculated and compared with those of other compounds M4AX3 (M = V, Nb, Ta; A = Al, Si and X = C). The predicted compound in the {\alpha}-phase is found to possess higher hardness than any of these compounds. The independent elastic constants of the two phases are also evaluated and the results discussed. The electronic band structures for {\alpha}- and {\beta}-Ta4SiC3 show metallic conductivity. Ta 5d electrons are mainly contributing to the total density of states (DOS). We see that the hybridization peak of Ta 5d and C 2p lies lower in energy and the Ta 5d-C 2p bond is stronger than Ta 5d-Si 3p bond. Further an analysis of the different optical properties shows the compound to possess improved behavior compared to similar types of compounds.Comment: 9 pages, 5 figures; PACS: 60.20.Dc; 62.20.-x; 71.15.Mb; 78.20.Ci; Keywords: Ta4SiC3, First-principles; Elastic properties; Electronic properties; Optical propertie
