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 Judges do not cite theoretical articles often; they rarely "apply" theories to particular cases.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.

A comparative study of new activity catecholase using complex based on three compounds type pentylidene-(4-vinylphenyl)-amine L1, butylidene-(4-vinyl-phenyl)-amine L2, sopentylidene-(4-methoxy-phenyl)-amine L3 has been reported. This study was performed to examine the catalytic effect of the in situ-generated copper (II) complexes towards catechol oxidation reaction with atmospheric dioxygen at room temperature. All complexes catalyze the studied reaction with the rate varying from a higher 9.5625 μmol L -1 min -1 for the L2[Cu(CH3CO2)2] to a weaker of 0.2500 μmol L -1 min -1 for L2[Cu(NO3)2]. The duplicating of ligand concentration influences in different way the oxidation rates. Against with an excess of catechol, the oxidation rate becomes very low.

To conduct a health risk assessment of some heavy metals attributed to consumption of common edible fish species available for consumers. Concentrations of Cd, Pb, Cu, Fe, Zn, Ni and Cr were determined in muscles, gills and livers, of two common edible fish species, namely Palaemon Serratus and Solea Vulgaris. Concentrations of heavy metals were determined by inductively coupled plasma- atomic emission spectroscopy (ICP-AES) and expressed as mg/kg of wet tissue. Results showed that iron and zinc were the most abundant among all fish tissues under investigation. The data obtained in the present work were compared well with the counterpart data reported internationally. The estimated values of all metals in muscles of fish in this study were below the permissible limits. Generally, risk values for the measured metals do not pose unacceptable risks at mean ingestion rate for muscles. It can be concluded that the investigated metals in edible parts of the examined species have no health problems for consumers.

The effect of Boc-phenylalanine (Boc-phe) on the corrosion of Cu60 - Zn40 in 0.5 M HNO 3 solution has been studied using weight loss and, electrochemical polarisation techniques. A significant retardation of the corrosionrates was observed in the inhibited nitric acid. Polarisation measurements indicated that Boc-phe acted as cathodic inhibitor without changing the mechanism of the hydrogen evolution reaction. The inhibition efficiency (E%) reached a maximum value of 96% for Boc-phe at 5 10 - 3 M. The result showed that Boc-phe adsorbs on the metal surface according to the Frumkin's isotherm. The effect of temperature in the range 303-353 K on the corrosion of Cu-Zn alloy in 0.5 M HN0 3 without and with addition of Boc-phe has been studied. The associated activation energy was determined.

Purpose: The objective of this paper is to make an investigation of spread of novel coronavirus (COVID-19) in MOROCCO and to estimate the duration of confinement for the fight against coronavirus disease 2019 (COVID -19). Methods: Data available on the sites provided by the Moroccan Ministry of Health, nonlinear regression, Gaussian function, residual sum of squares and regression curve. Results: Moroccan citizens must stay at home as much as possible until June 12, 2020. Conclusion: Given the non-existence of a vaccine or an effective treatment against the coronavirus (COVID-19), our research team believes that confinement remains the best solution to limit the spread of this pandemic.

The inhibition effect of 3-methyl-4-(3-methylisoxazol-5-yl)isoxazol-5(2H)-one monohydrate (P1) on the corrosion of carbon steel in 1 M HCl was studied by weight loss, electrochemical impedance spectroscopy (EIS) techniques and potentiodynamic polarization methods. The results showed that isoxazole P1 was a good inhibitor in 1 M HCl and inhibition efficiency increases with isoxazole P1 concentration to attain 93% at 10-3M at 308 K. E(%) values obtained from various methods used are reasonably good agreement. The adsorption of isoxazole P1 obeyed the Langmuir adsorption isotherm. Polarization curves showed that isoxazole P1 acted as a mixed-type inhibitor in HCl. The effect of the temperature on the corrosion behavior with addition of 10-3M of the inhibitor was studied in the temperature range 313-343 K, and the thermodynamic parameters were determined and discussed. In addition, a quantum chemical study suggests isoxazole P1 inhibitor is structurally essential for the protection of metal surface
