Ethical aspects in managing patients diagnosed with digestive cancers; a review of literature

Numerous bioethical recommendations are now available in the complex process of communication with cancer patients. In this review, we have focused on the complex process of managing patients with different types of oncologic digestive diseases, immediately after the diagnosis is made. We have analyzed the literature data on the topic. MEDSCAPE and PubMed databases have been studied. Issues such as telling the truth to patients with digestive cancer, the physician\u27s responsibility in the psychological management of patients and their relatives, the nurses’ duties, the consented death, the practice of euthanasia and physician-assisted suicide (PAS) as well as the clinical research have been the main targets of our study

Researches Regarding Structural Changes due to nickel Microlalloying of Hot Galvanizing Baths

This work offers a synthesis of researches performed in laboratory and regards the nickel microalloying of hot galvanizing baths. Experiments followed the structural changes of both hot galvanizing bath and deposed layer with effect on layer properties. Characterization of deposed layer and nickel microalloying of galvanizing bath performed by spectral chemical analysis, optical microscopy and X ray diffraction emphasized the structural constituents nature as well as changes shown up depending on nickel concentration of galvanizing bath. Correlation diagrams between deposed layer thickness and structural constituents were also made. Experimental results emphasized a close interdependence between nickel concentration and microstructure. This allowed to settle the optimal nickel concentration required by galvanizing bath microalloying with maximum effect upon hot galvanizing coating properties

Polychlorinated biphenyls in Bucharest urban soils

Polychlorinated biphenyls are a family of 209 congeners that were manufactured and sold as complex mixtures differing in their chlorination level. They have excellent dielectric properties, chemical and thermal stability, so they were used extensively in industry. PCBs are very persistent, very toxic, and the high octanol/water partition coefficient results in their accumulation in fatty tissues and their biomagnification in the food chain. These are the reasons of including polychlorinated biphenyls on the Persistent Organic Pollutants list adopted in Stockholm in 2001. This paper presents the PCBs (28, 52, 101, 138, 153, 180) load level of Bucharest soils. The samples were collected from representative areas such as parks, streets, intersections, markets. The interest compounds were extracted from soil with organic solvents and analyzed by gas chromatography with electron capture detector. The analythical results show that the most abundant compounds were those with a high degree of chlorination. Thus, for PCB 180, 90% from analyzed samples have concentrations ranged between normal values (< 0.0004 mg/kg) and alert threshold (0.01 mg/kg), 7% between alert and intervention threshold (0.04 mg/kg), while only 3% exceed the intervention threshold. For PCB 153, again, 90% of the values are within the interval normal range – alert threshold and 10% correspond to the interval alert threshold – intervention threshold. For PCB 138, 23% from soil samples have normal concentration, 70% exceed the normal values but are lower than alert threshold, while 7% exceed the alert threshold. The highest concentration value, 0.0542 mg/kg, was recorded for PCB 180 in a sample collected close by a very busy boulevard

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN

First bioanthropological evidence for Yamnaya horsemanship

The origins of horseback riding remain elusive. Scientific studies show that horses were kept for their milk ~3500 to 3000 BCE, widely accepted as indicating domestication. However, this does not confirm them to be ridden. Equipment used by early riders is rarely preserved, and the reliability of equine dental and mandibular pathologies remains contested. However, horsemanship has two interacting components: the horse as mount and the human as rider. Alterations associated with riding in human skeletons therefore possibly provide the best source of information. Here, we report five Yamnaya individuals well-dated to 3021 to 2501 calibrated BCE from kurgans in Romania, Bulgaria, and Hungary, displaying changes in bone morphology and distinct pathologies associated with horseback riding. These are the oldest humans identified as riders so far
