Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Much has been written about theory and practice in the law, and the tension between practitioners and theorists. Judges do not cite theoretical articles often; they rarely "apply" theories to particular cases. These arguments are not revisited. Instead the Essay explores the working and interaction of theory and practice, practitioners and theorists. The Essay starts with a story about solving a legal issue using our intellectual tools - theory, practice, and their progenies: experience and "gut." Next the Essay elaborates on the nature of theory, practice, experience and "gut." The third part of the Essay discusses theories that are helpful to practitioners and those that are less helpful. The Essay concludes that practitioners theorize, and theorists practice. They use these intellectual tools differently because the goals and orientations of theorists and practitioners, and the constraints under which they act, differ. Theory, practice, experience and "gut" help us think, remember, decide and create. They complement each other like the two sides of the same coin: distinct but inseparable.

The electrochemical oxidation of dicofol pesticide was performed using a boron doped diamond (BDD) electrode, commercially available at Adamant Technologies. Tests were performed with model solutions of dicofol, with concentrations ranging from 25 to 75 ppm for the BDD electrode, using different concentration of NaCl as the electrolyte, in a batch cell, at different current densities (30, 50 and 70 mAcm -2 ). GS/MS and Chemical Oxygen Demand (COD) tests were conducted for all samples. The results have shown a very good degradation of dicofol pesticide, with COD removals between 53 and 89% and % removals for concentration varying from 77 to 97%, in 3 hours experiments. General Current Efficiency and Mineralization Current Efficiency, determined for BDD electrode, show a good degradation for 70mAcm -2 but a very less at 30 mAcm -2 . The best obtained conditions for COD removal on the BDD anode to degrade dicofol solutions include operating at 70 mA cm -2 and 25 Â°C. The high efficiency of this technology can be explained in terms of the direct electrooxidation at the BDD surface and the oxidation carried out by hydroxyl radicals (OHâ€¢) and other electrogenerated oxidants (Cl - , ClO - ).

Oxidation of the Pesticide Dicofol at Boron-Doped Diamond Electrode

Various techniques carried out to reduce or decrease the corrosion rate of materials and metal alloys. The use of green inhibitors is one of the most practical techniques used against this phenomenon. In this work, we have studied the influence of aqueous extracts of ginger rhizomes on the corrosion of mild steel in 1M HCl acid medium by electrochemical measurements: polarization curve, electrochemical impedance spectroscopy and weight loss measurements. The results showed that the inhibition efficiency was found to increase with inhibitor content to attain 95% in the presence of the ginger concentration 10-3M at 308K. The effect of temperature on the behaviour of corrosion showed that the inhibition efficiency of deferent extracts decreased significantly with temperature. The adsorption of various extracts on the steel surface follows the Langmuir’s adsorption isotherm.

The preparation of new (MeC(CH2PPh2)3CuCl) 1 and its derivatives was carried out directly by mixing of CuCl and MeC(CH2PPh2)3 ligand in dry THF, the neutral precursor 1 served to prepare (MeC(CH2PPh2)3Cu(NCCH3))BF4 2 and (MeC(CH2PPh2)3Cu(PCH2Ph)3)BF4 3. These complexes are characterized on the basis of elemental analysis, IR, EDS, 1 H, 13 C and 31 P{ 1 H}NMR, FAB-MS, TG/ DTA and single-crystal X-ray diffraction studies. Complex 1 crystallizes in the Orthorhombic unit cells with the space group Pna2(1). The structural behavior of MeC(CH2PPh2)3 ligand in the formed complexes during the coordination reaction was monitored by 31 P{ 1 H}NMR in CDCl3 at room temperature for the first time.

Adsorbent materials were prepared from Moroccan oil shale of Timahdit (layer Y) The objective is to optimize the procedure parameters of elaboration the adsorbents from two precursors; the raw rock Y and the decarbonated raw rock YH The parameters examined in this study are: the activation temperature, the residence time in the furnace and the atmosphere gas The textural and structural characteristics of the prepared adsorbents and their removal capacity of the methylene blue molecule revealed that the best adsorbents are obtained upon activation of the two precursors at 300 °C in air but with durations of different activation, 2h for Y and 230 for YH Under these conditions the prepared adsorbents are characterized by significant textural and structural properties; a maximum adsorption capacity of methylene blue molecule that can reach 175 mg/g in the case (YH300 (2:30) in addition to the development of surface function
