In this report, we discuss two approximate max-flow min-cut theorems that first introduced by Tom Leighton and Satish Rao in 1988 [9] and extended in 1999 [10] for uniform multicommodity flow problems. In the theorems they first showed that for any n-node multicommodity flow problem with uniform demands, the max-flow is a Ω(log n) factor smaller than the min-cut; further,they proved the max-flo...

The effects of four cut types (wedges, slices, 1/2 and 1/4 slices) of ‘Lisbon’ lemons (Citrus lemon L.) and storage at four temperatures (0, , 5 and 10 ◦C) on post-cutting life were studied. Respiration rates of all cut types that were stored at 0, 2 and 5 ◦C up to 8 days were 2–5 times igher than those of the whole lemons, while the increase was up to 12-fold at 10 ◦C. Small differences among ...

Fresh-cut cantaloupe is particularly susceptible to contamination with pathogenic bacteria, such as Escherichia coli O157:H7, Listeria monocytogenes, and Staphylococcus aureus. Therefore, development of rapid, yet accurate detection techniques is necessary to ensure food safety. In this study, a multiplex PCR system and propidium monoazide (PMA) concentration were optimized to detect all viable...

Optimal temporal modulation of the stimulus can improve foveal contrast sensitivity. This study evaluates the characteristics of the peripheral spatiotemporal contrast sensitivity function in normal-sighted subjects. The purpose is to identify a temporal modulation that can potentially improve the remaining peripheral visual function in subjects with central visual field loss. High contrast res...

BACKGROUND Accurate assessment of physical activity among coronary artery disease patients is important for assessing adherence to interventions. The study compared moderate-to-vigorous physical intensity activity and relationships with cardiometabolic health/fitness indicators using accelerometer cut-points developed for coronary artery disease patients versus those developed in younger and mi...

UNLABELLED The aim of this study was to analyze the usefulness of the International Personality Disorder Examination Screening Questionnaire (IPDE-SQ) for identifying DSM-IV and ICD-10 Borderline and Impulsive personality disorders (PD) in Spanish adolescents. METHOD The DSM-IV and ICD-10 IPDE-SQ screeners were used and compared with the diagnoses obtained with the IPDE semistructured intervi...

Chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. In order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a RCD with 10 treatments: Artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), Ri...

OBJECTIVE To establish guidelines for postnatal referral of fetuses presenting with mild pyelectasis in the second trimester of pregnancy. METHODS In a retrospective study, 87 fetuses with a renal pelvis anteroposterior (RPAP) diameter of > or = 4 mm and < or = 10 mm before 28 weeks of gestation were included. All patients had a third-trimester scan and fetuses with an RPAP diameter of > or =...

The aim of this study is investigation on effect of stem end splitting and Geranium essential oil on vase life on quality of cut chrysanthemum (Dendranthema grandiflorum L.). This experiment arranged as factorial based on RCD with 2 factors of stem end splitting at 2 levels (with splitting and without splitting) and Geranium essential oil at 6 levels (0, 1, 2, 4, 8 and 10 %), with 12 treatments...

BACKGROUND The prevalence of depressive symptoms in hypothyroidism is high. Considering that hypothyroidism and depression share some clinical features, some researchers use the "brain hypothyroidism" hypothesis to explain the pathogenesis of depression. We aimed to detect a new TSH cut-off value in hypothyroidism based on depression symptoms. METHODS A cross-sectional study was conducted on ...
