OBJECTIVE To examine the association between shift work and unhealthy weight among female nurses and midwives. METHODS A cross-sectional study. Measurement outcomes included shift work, unhealthy weight (underweight: body mass index [BMI] < 18.5; overweight: BMI 25.0 to 29.9; obesity: BMI > 30.0), diet quality, physical-activity level, alcohol consumption, and smoking status. RESULTS Among ...

Recently, a functional polymorphism in KITLG, rs4590952, was identified to be associated with testicular cancer susceptibility through increasing the p53-dependent KITLG expression and disrupting the function of p53. We performed a hospital-based case-control study, including 1241 breast cancer (BC) patients and 1259 cancer-free controls, to investigate the role of this polymorphism in the risk...

Breath testing for volatile organic compounds (VOCs) provides an intrinsically safe method for investigating human metabolism. An improved breath-collecting apparatus (BCA) is described which was acceptable to patients, simple to use, highly sensitive, and free from chemical contamination. VOCs in 10.0 L alveolar breath and 10.0 L room air were collected onto adsorptive traps. Using automated i...

O presente artigo tem como objetivo trazer o conceito de consciência globalidade para a análise culturas pré-modernas, tendo objeto estudo as crônicas cosmográficas medievais, tipificadas por Anne-Dorothee von den Brincken (1969), imago mundi. Serão trazidos trechos da mundi do Atlas Catalão (1375) e Libro las Cruzes (1961/1259), com foco nesse último. A considerar definição Roland Robertson (1...

in this study, hydrus2d/3d software was used to estimate the hydraulic parameters of van genuchten-mualem model via inverse modeling using double-ring infiltrometers data in 3 different soil textures. nine scenarios of inverse modeling (divided in three groups) were considered with different number (5, 4 and 3) of fitted hydraulic parameters for optimization. in the first group, simulation was ...

The pulsar PSR B1259−63 is in a highly eccentric 3.4-yr orbit with the Be star SS 2883. Timing observations of this pulsar, made over a 7-yr period using the Parkes 64-m radio telescope, cover two periastron passages, in 1990 August and 1994 January. The timing data cannot be fitted by the normal pulsar and Keplerian binary parameters. A timing solution including a (non-precessing) Keplerian or...

We report here on multifrequency radio observations of the pulsed emission from PSR B1259–63 around the time of the closest approach to its B2e companion star. There was a general increase in the pulsar’s dispersion measure and scatter broadening, and a decrease in the flux density towards periastron although changes in these parameters were seen on timescales as short as minutes. The pulsed em...

Nonpulsed but variable X-ray emission has been detected from the binary system containing the radio pulsar PSR 1259–63 during two pointed ROSAT observations, taken five months apart. This 47.7 ms radio pulsar is in a highly eccentric (2 ∼ .85) binary system with the 10 to 15 M ̄ Be star SS2883. It is the first radio pulsar found to be in a binary system with a massive main sequence companion; it...
