STUDY OBJECTIVES To evaluate the pulmonary manifestations and the course of acute respiratory insufficiency associated with lysinuric protein intolerance (LPI). DESIGN Retrospective review of clinical data and chest radiographs (total 225) obtained during the lifetime follow-up of 31 LPI patients. About half of the 25 patients without respiratory symptoms underwent high-resolution computed to...

Crop nitrogen status is a major issue for crop yield and quality. It is usually assessed by destructive leaf or petiole tissue analysis. A quantitative nondestructive optical estimation of N sufficiency would be a great leap forward toward precision crop management. We therefore calibrated three optical indices against leaf nitrogen content: chlorophyll (Chl), epidermal flavonols, and the nitro...

Leaf biomass distribution is a key factor for modeling energy and carbon fluxes in forest canopies and for assessing fire behavior. We propose a new method to estimate 3D leaf bulk density distribution, based on a calibration of indices derived from T-LiDAR. We applied the method to four contrasted plots in a mature Quercus pubescens forest. Leaf bulk densities were measured inside 0.7 m-diamet...

AIM The general goal of this study is to investigate and analyze patterns of ecophysiological leaf traits and spectral response among life forms (trees, shrubs and lianas) in the Cerrado ecosystem. In this study, we first tested whether life forms are discriminated through leaf level functional traits. We then explored the correlation between leaf-level plant functional traits and spectral refl...

This paper presents Higher Order Spectral Analysis (HOSA) and Artificial Neural Network techniques for identification of LPI (Low Probability of Intercept) Radar signal. Common Spectral analysis and conventional methods fail to detect low powered emissions of LPI Radars and even normal radars in noisy environments. This leads us to use Higher Order Spectral Analysis (HOSA) techniques (bi-spectr...

This study characterizes the leachates quality of an active dumpsite in Warri, Delta State and also analyses its contamination or pollution potential. Leachate Pollution Index (LPI) a tool for quantifying pollution potential of leachates generated from dumpsites has been used to quantify the leachates contamination potential of the dumpsite. The LPI values for the different sample locations L1,...

The Low Probability of Intercept (LPI) capability of the radar defeats conventional RWR/ESM systems. The important advantage of LPI radar is to go undetected, while maintaining a strong battlefield awareness. Common Spectral analysis and conventional methods fail to detect emissions of LPI Radars and even normal radars in noisy environments. This leads to use Higher Order Spectral Analysis (HOS...

The retention of foetal membranes (RFM) is supposed to be related to oxidative stress which can be evaluated through indirect and direct parameters, among others, total antioxidant capacity (TAC) and lipid peroxidation intensity (LPI). Placental samples (maternal and foetal parts) were collected from Holstein-Friesian healthy cows immediately after caesarean section (n = 13, group A) at time or...
