Colorectal cancer is one of the predominant tumors in the world,primarily generated by a progression from polyp to cancer which can last several years,giving a great opportunity to the scientific community for its prevention by screening programs that can be done with invasive and non-invasive *** this issue,Lopes et al show us an excellent review of screening,its options,its advantages and disadvantages.

The objective of this paper relies on the establishment of the sampling moment and the nutritional state of the species Conilon coffee (Coffea canephora) cultivated in Cambisoils. The effect of different rates of nitrogen fertilization was also studied in the leaves concentrations of N, at randomized complete block designs (N 0 = 0; N 1 = 50; N 2 = 100; N 3 = 150 and N 4 = 200 kg?ha -1 of N) in presence of P (40 kg?ha -1 of P 2 O 5 ) and K (160 kg?ha -1 of K 2 O), with four replicates. The samples were carried out in the months of March (flower blossoming stage), June (fruits growing stage), September (grain development) and December (maturation) in all treatments. Foliar analysis carried out in the month of June (fruits growing stage) for the purpose of establishing critical nutrient range values for N, settling down approaches of interpretation of the same one for the Conilon coffee plantations on Cambisoils. The biggest percentages in the yields are obtained with leaves containing N between 2.80% and 3.10%, a value below 2.80% N which they associated with indicative percentages of stable maximum yield that did not surpass the limits of the adequate nutrients supply.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced *** paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS *** taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet *** in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.
