No problem is ever permanently closed. The editor is always pleased to consider for publication new solutions or new insights o n p a s t p r oblems. (1) Determine the set of all c > 0 such that whenever (1) holds, then we have x + y + z xy + yz+ zx. The positive r eals c asked for are those satisfying c 4. From (1), we have xy < c and z = c ; xy x + y + xy. Substituting this value of z into th...

BACKGROUND Green spaces have been associated with improved physical and mental health; however, the available evidence on the impact of green spaces on pregnancy is scarce. OBJECTIVES We investigated the association between surrounding greenness and birth weight, head circumference, and gestational age at delivery. METHODS This study was based on 2,393 singleton live births from four Spanis...

The paper focuses on the investigation of unsteady effects in shock wave/boundary layer interaction. study was carried out using a flat plate model subjected to free stream Mach number 1.43 and unit Reynolds (Re1) 11.5 × 106 1/m. To generate two-dimensional disturbances laminar boundary upstream separation region, dielectric barrier discharge employed. were generated within frequency range 500 ...

A new spherical tokamak, the SMall Aspect Ratio Tokamak (SMART), is currently being designed at University of Seville. The goal machine to achieve a toroidal field 1 T, plasma current 500 kA and pulse length ms for with major radius 0.4 m minor 0.25 m. This contribution presents design coils power supplies machine. foresees central solenoid, 12 8 poloidal coils. Taking waveforms these set as st...

Increasing freshwater input to the subpolar North Atlantic through iceberg melting can influence fjord-scale basin-scale ocean circulation. However, magnitude, timing, and distribution of this have been challenging quantify due minimal direct observations subsurface geometry melt rates. Here we present novel in situ methods capturing change at high-temporal -spatial resolution using four high-p...

Sparidae family is one of the most important demersal group for Turkish fisheries. When considering importance Turkey fisheries, population parameters Pagellus acarne Risso, 1827 have a many proposition future fisheries studies. Studies biology and this species are very limited in Aegean Sea; therefore we aimed to determine (length-weight relationship, age growth parameters, mortality rates rep...

The purpose of this perspective study was to evaluate which prognostic factors predict long-term survival and disease-free survival (DFS) of elderly patients (> or = 65 years) who underwent surgery for colorectal carcinoma. Between January 1992 and December 1998, 196 colorectal cancer patients > or = 65 years (114 M; 82 F; mean age: 75 years; range: 65-92) underwent surgery. One hundred forty-f...
