Inspired by the work of Suzuki in [T. Suzuki, A generalized Banach contraction principle that characterizes metric completeness, Proc. Amer. Math. Soc. 136 (2008), 1861--1869], we prove a fixed point theorem for contractive mappings that generalizes a theorem of Geraghty in [M.A. Geraghty, On contractive mappings, Proc. Amer. Math. Soc., 40 (1973), 604--608]an...
Abstract Brazilian potato production is based on cultivars originating from the USA and Europe; however, these were developed under different environmental conditions than those found in Brazil. The aim of this study was to evaluate adaptability stability 18 clones (MLG), by Universidade Federal de Lavras, four six environments state Minas Gerais, following traits evaluated: marketable tuber yi...

We point out that the theorem of the paper listed in the title is a known result. 1. Main resultIn [1] the following theorem was proved.Theorem 1.1. Let (X, d) be a complete metric space, T : X → CB(X) such thatH(Tx, Ty) ≤αd(x, y) + β[D(x, Tx) + D(y, Ty)]+ γ[D(x, Ty) + D(y, Tx)]for all x, y ∈ X where α, β, γ ≥ 0, α + 2β + 2γ < 1. Then T has a fixed point.The theorem appe...
a greenhouse experiment was conducted in 2013 in research lab of karaj islamic azad university to determine the yield and activity of chemical markers as the response to different concentrations of cadmium (cd) (0, 5, 10 and 20 mg of cd/kg of soil) in wheat cultivars (karaj 1 and karaj 2). treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. the respon...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...

I N T R O D U C T I O N In 1968, Ulam [1] proposed the general problem: "When is it t rue tha t by changing a l i t t le the hypotheses of a theorem one can still assert t ha t the thesis of the theorem remains t rue or approx imate ly t rue?" In 1978, Gruber [2] proposed the following Ulam type problem: "S...

Transplantation for Acute Liver Failure in Patients Exposed to NSAIDs or Paracetamol (Acetaminophen)
BACKGROUND Most NSAIDs are thought to be able to cause hepatic injury and acute liver failure (ALF), but the event rates of those leading to transplantation (ALFT) remain uncertain. OBJECTIVES The aim of the study was to estimate population event rates for NSAID-associated ALFT METHODS: This was a case-population study of ALFT in 57 eligible liver transplant centres in seven countries (France...
development of yeast artificial chromosome (y ac) vectors, molecular cloning of large segments of chromosomal dna, and their propagation in yeast cells has become feasible. overlapping y ac provides a route to the development of physical maps of entire mammalian chromosomes. a rapid method was developed to isolate and sequence termini of y ac inserts quickly. the y ac clone is digested with a r...
