One of the major challenges of anaerobic technology is its applicability for low strength wastewaters, such as sewage. The lab-scale design and performance of a novel Gradual Concentric Chambers (GCC) reactor treating low (165±24 mg COD/L) and medium strength (550 mg COD/L) domestic wastewaters were studied. Experimental data were collected to evaluate the influence of chemical oxygen demand (COD) concentrations in the influent and the hydraulic retention time (HRT) on the performance of the GCC reactor. Two reactors (R1 and R2), integrating anaerobic and aerobic processes, were studied at ambient (26°C) and mesophilic (35°C) temperature, respectively. The highest COD removal efficiency (94%) was obtained when treating medium strength wastewater at an organic loading rate (OLR) of 1.9 g COD/L·d (HRT = 4 h). The COD levels in the final effluent were around 36 mg/L. For the low strength domestic wastewater, a highest removal efficiency of 85% was observed, producing a final effluent with 22 mg COD/L. Changes in the nutrient concentration levels were followed for both reactors.

The aim of this study was to examine the strength of scientific evidence, reproducibility and replicability of the 29 essays of the winners of the Bigelow contest.Six essays (20.5%) were included in the category with the high strength of scientific evidence. Four essays (14%) were included in the category with medium strength of scientific evidence and the remaining 19 essays (65.5%) in the category with low strength of scientific evidence. The overall agreement between our strength of scientific evidence categories and the Bigelow ones, was only 48.8%, sufficient to demonstrate a clear difference between our scientific criteria and those adopted by the judges of the Bigelow contest.The essays that obtained the highest strength of scientific evidence level were related to near-death experiences and mental mediumship.For other phenomena, more studies with refined experimental designs are necessary to increase the evidence of the survival of human consciousness.

Introduction: Social and personality psychologists have described Machiavellianism as a pragmatic, callous-unemotional, exploitative and manipulative attitude towards others. Several former studies linked Machiavellian personality traits and interpersonal problems or personality dysfunction. Aim: The aim of this study was to reveal the connection between Machiavellianism and interpersonal problems that are characteristic of personality disorders. Method: 252 participants (146 females and 106 males, aged 32.46±5.39 years, mean±SD) filled out self-report measures of Machiavellianism and personality disorder related interpersonal problems. Results: There was a medium strength relationships between Machiavellianism and several interpersonal problems. Aggression and ambivalence proved to be significant predictors of Machiavellian personality traits. Conclusions: Results are discussed in relation to the patient–therapist bond. Orv.

Abstract ANACONDA Alloy 360 is a leaded brass and is the alloy most often used for high-speed machining operations; it fills most of the needs for such purposes. Alloy 360 is the standard free-cutting brass and its machinability has become the standard by which all other copper-base alloys are rated. It has medium strength and ductility. Alloy 360 is used for hardware such as gears and pinions where excellent machinability is of prime importance and for all types of automatic high-speed screw-machine products. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-447. Producer or source: Anaconda American Brass Company.
