Produção De Minitomate Em Sistema Orgânico Sob Ambientes Protegidos Com Controle Parcial De Elementos Meteorológicos

The objective of this research was to evaluate the meteorological elements of the environments and the production components of mini tomato crop in organic system in different forms of cultivation, biofertilizer doses and technological levels of protected environments. The research was conducted in completely randomized design in a 3 × 2 × 5 factorial scheme, corresponding to three greenhouses (A - climatized, B - mobile screen and C - fixed screen), two forms of cultivation (pots and beds) and five doses of a commercial biofertilizer (0, 50, 100, 150 and 200% of dose indicated), with five replicates. The treatments affected the analyzed variables, except for biofertilizer doses and interaction of treatments. Air temperature was unchanged among the environments and the mean and minimum relative humidity were within the control range in the climatized greenhouse. The greenhouse with mobile screen showed the best production results for the cultivation in beds and the biofertilizer doses were indifferent for all treatments. © 2016, Departamento de Engenharia Agricola - UFCG/Cnpq.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Confinement And Zone Folding In The E1-like Optical Transitions Of Ge/si Quantum Wells And Superlattices

We report low-temperature (77 K) electroreflectance and photoreflectance measurements of the E1-like optical transitions on a series of Ge/Si heterostructures (superlattices and quantum wells). For single and double quantum wells of any thickness, as well as for thick-layer superlattices (period ∼100 ) the spectra can be understood in terms of quantum-confined bulk-Ge E1 states. For thin (∼10 ) multiple quantum wells and superlattices, zone-folding effects dominate the spectra. Actual confinement of the electronic states is determined by measuring the Raman spectrum of each sample in and out of resonance with a given transition. © 1993 The American Physical Society.4824180241803
