This research was aimed at developing an efficient method for Nitrogen, Phosphorus, and Potassium (NPK) foliar content retrieval in olive trees by means of the analysis and modelling multispectral ...images taken by an unmanned aerial vehicle (UAV) under field conditions. To this end, an experiment was carried out in a super hight density olive orchard. The fertirrigation system of the experimental area was sectorized to obtain plots with different status of NPK. The orchard was overflown with a UAV equipped with a multispectral camera that photographed the entire experimental surface. A new image analysis approach was developed for integrating all the spectral images gathered during the flight in orthomosaics from which to automatically extract information from discrete points. Finally, several retrieval techniques (partial least squares regression, artificial neural network (ANN), support vector regression and Gaussian process regression) were evaluated for NPK leaf content retrieval by using the spectral data as input variables, and the results of chemical analyses as reference. Among all, the best results were obtained by ANN approach (N (R2 = 0.63), P (R2 = 0.89), K (R2 = 0.93)). These results showed the suitability of the proposed image processing approach and indicate ANN as the best recovery technique for the experimental conditions evaluated. However, the approach must be validated under other environmental conditions, olive varieties and plant vegetative stages before making fertilization recommendations.
•Method for NPK leaf content retrieval in olive trees by means of multispectral data.•Multispectral images taken by a UAV under field conditions.•Image analysis algorithm to automatically extract information from discrete points.•ANN showed better results than PLSR, SVR and GPR.
Bone and joint tuberculosis (BJTB) is rare in developed countries, particularly in the paediatric population.
The clinical features and sequelae of paediatric BJTB in Europe are not well ...characterized and should be assessed to achieve a better approach.
To assess the management and outcomes of paediatric BJTB.
Longitudinal observational study of all paediatric patients (0-17 years old) diagnosed with BJTB between 2008 to 2020 in a tertiary-care hospital.
We identified 18 patients with BJTB, with a median age of 10 years (IQR 6-14.8), 66.7 % male. Most (72 %) were diagnosed after 2015 and were foreign-born (88.9 %), mainly from Portuguese-speaking African countries, and none had HIV. The most common symptoms were pain (77.8 %), fever (50 %) and bone deformity (44.4 %). Spinal TB (STB) affected 13 (72.2 %) and extra-spinal TB (ESTB) 9 (50 %) patients, and 4 (27.7 %) had both conditions. Diagnostic positive procedures included positive nucleic acid amplification technique (NAAT) (44.4 %),
isolation (44.4 %) and compatible histology (33.3 %). All completed antituberculous drugs for a median of 12 months (IQR 12-13) and nine (50 %) had surgery. Overall, acute complications occurred in 16 (88.9 %) patients - 11/13 (84.6 %) with STB and 5/5 (100 %) with ESTB - and included abscesses, spinal compression, spine deformity and pathological fractures. Sequelae were still present at the 12-month follow-up in seven cases (46.7 %), and were more common in foreign-born patients sent to Portugal to receive medical treatment (66.7 vs 20 %).
Paediatric BJTB is difficult to diagnose and has high morbidity, requiring long-term follow-up. Over the last decade, foreign-born TB seems to be increasing, with still longer treatment courses and more acute complications and sequelae.
According to EU commission statements dated of 2019, around 95% of car accidents in the EU have some type of human error involved. Autonomous cars may reduce this number significantly and improve ...road safety thanks to many softwares and driving aids. It is expected that the self-driving vehicles’ market grows exponentially and reaches profits of up to 620 billion euros by 2025. This is due to its environmental footprint and the reduced financial cost of electric energy. However, this increasing autonomy has raised awareness in the insurance industry. Cars’ automation is not currently a factor used in insurance pricing models. The purpose of this project is to detail the difference in claim frequency and claim amount for cars with ADAS (Advanced Driver Assistance Systems) and analyze if this should be taken into account when calculating car insurance premiums. Generalized linear models, along with Decision Trees will be used to analyze the impact of ADAS in aggregated claim amount.
We present a 10-year-old boy with 2-month duration non-traumatic wrist pain and inflammatory signs. Due to elevated inflammatory markers on blood tests, with an increase in radiocarpal and ...intercarpal joints synovial fluid and no bony lesions, the patient was submitted to wrist arthrocentesis for the suspicion of septic arthritis. The patient did not improve on conventional treatment, however. An MRI showed synovitis around the carpus and a lytic lesion of the capitate bone due to osteomyelitis. A biopsy was able to identify the causative agent as Mycobacterium tuberculosis, and the patient was treated with antibiotics. He improved significantly, with no pain and signs of normal capitate bone remodelling on the last radiograph.
