Mapping daily evapotranspiration at field to continental scales using geostationary and polar orbiting satellite imagery
2011
Abstract. Thermal infrared (TIR) remote sensing of land-surface temperature (LST) provides valuable information about the sub-surface moisture status required for estimating evapotranspiration (ET) and detecting the onset and severity of drought. While empirical indices measuring anomalies in LST and vegetation amount (e.g., as quantified by the Normalized Difference Vegetation Index; NDVI) have demonstrated utility in monitoring ET and drought conditions over large areas, they may provide ambiguous results when other factors (e.g., air temperature, advection) are affecting plant functioning. A more physically based interpretation of LST and NDVI and their relationship to sub-surface moistu…
The consequences of the inappropriate use of ventilation systems operating in indoor swimming pool conditions - analysis
2018
Increasingly more leisure facilities, such as water parks or indoor swimming pools are being built in Poland nowadays. In order to ensure the air quality required by standards for such leisure facilities it is necessary to fit them with effectively functioning ventilation. For the removal of excess humidity, as well as chlorine ions occurring as a result of the disinfection of water as well as the carbon dioxide emitted by people using the facility, the ventilation system needs to be appropriately designed and efficient. For this reason, studies into the air quality in such facilities were undertaken. The paper presents the causes and consequences of the inappropriate operation and maintena…
Endothelial nitric oxide synthase gene polymorphisms and cardiovascular damage in hypertensive subjects: an Italian case-control study
2008
Abstract Background Nitric oxide (NO) synthesized by endothelial nitric oxide synthase (eNOS) plays an important role in regulation of endothelial function and in the control of blood pressure. However, the results from some studies on the association between three clinically relevant eNOS gene polymorphisms (G894T, T786C and intron 4b/a) and essential hypertension are unclear. We designed a case-control study to evaluate the influence of eNOS polymorphisms on target organ damage in 127 hypertensives and 67 normotensives. Clinical evaluation, biochemical parameters, Urinary Albumin Excretion (UAE) and echocardiogram were performed to characterize target organ damage. eNOS polymorphism were …

FETAL GROWTH RESTRICTION: A GROWTH PATTERN WITH FETAL, NEONATAL AND LONG-TERM CONSEQUENCES
2019
Fetal growth restriction (FGR) or intrauterine growth restriction (IUGR) are the terms used for a fetus which has not attained its full growth potential for gestational age. FGR is a multifactorial syndrome responsible for increased fetal and neonatal morbidity and mortality as well as long term adverse outcomes involving auxological, metabolic, organic and functional domains. Clinicians distinguish early and late onset FGR, in relation to specific fetal anthropometric parameters related to the possible primary etiology and to different patterns of placental and maternal cardiovascular pathologies. Delivery of an early onset FGR or growth impaired newborn with congenital pathology should be…

Why the share of small amount pensions is so substantial in Latvia?
2018
More than 70% of all old-age pensions in Latvia are smaller than 300 euro, which is close to the monetary value of the at-risk-of-poverty threshold. There is a number of reasons for it: the lack of non-contributory component and inadequately low minimum pensions, the absence of redistribution mechanisms in the mandatory notional defined contribution (pillar I) and funded (pillar II) schemes, an unfair conversion of pre-reform employment record into pension formula, and a high tax burden on pensioners. The authors proposed a package of measures to improve the situation: an introduction of basis pensions, linking minimum pensions to the country average wages, increasing income tax exempt for …
Device-Based Measures of Sedentary Time and Physical Activity Are Associated With Physical Fitness and Body Fat Content
2020
Introduction/Purpose: Physical activity and sedentary time may associate with physical fitness and body composition. Yet, there exists some observational studies that have investigated the associations of device-based measures of sedentary time and physical activity (PA) with cardiorespiratory fitness (CRF) and body composition but associations with muscular fitness (MF) are less studied.Methods: Objective sedentary time and physical activity was measured by a hip worn accelerometer from 415 young adult men (age: mean 26, standard deviation 7 years). Cardiorespiratory fitness (VO2max) (CRF) was determined using a graded cycle ergometer test until exhaustion. Maximal force of lower extremiti…
Crop Nitrogen Retrieval Methods for Simulated Sentinel-2 Data Using In-Field Spectrometer Data.
2021
Nitrogen (N) is one of the key nutrients supplied in agricultural production worldwide. Over-fertilization can have negative influences on the field and the regional level (e.g., agro-ecosystems). Remote sensing of the plant N of field crops presents a valuable tool for the monitoring of N flows in agro-ecosystems. Available data for validation of satellite-based remote sensing of N is scarce. Therefore, in this study, field spectrometer measurements were used to simulate data of the Sentinel-2 (S2) satellites developed for vegetation monitoring by the ESA. The prediction performance of normalized ratio indices (NRIs), random forest regression (RFR) and Gaussian processes regression (GPR) f…
