BACKGROUND Evidence suggests that air pollution exposure adversely affects pregnancy outcomes. Few studies have examined individual-level intraurban exposure contrasts. OBJECTIVES We evaluated the impacts of air pollution on small for gestational age (SGA) birth weight, low full-term birth weight (LBW), and preterm birth using spatiotemporal exposure metrics. METHODS With linked administrat...

The purpose of this study is to investigate the accuracy Inverse Distance Weighted (IDW) interpolation method estimate and map surface water salinity along coastal waters Pulau Tuba, Langkawi. Sea was recorded using a refractometer during two sampling activities that were carried out in November 2018. Global Positioning System (GPS) used record geo-location each point. IDW applied data collecti...

High-precision rainfall information is of great importance for the improvement accuracy numerical weather prediction and monitoring floods mudslides that affect human life. With rapid development satellite constellation networks, there potential reconstructing high-precision fields in large areas by using widely distributed Earth–space link (ESL) networks. In this paper, we have carried out res...

Bu çalışmada, Türkiye'nin uzun vadeli aylık toplam yağış miktarı (mm) iki farklı enterpolasyon yöntemi kullanılarak tahmin edilmiştir. Yağış miktarı, komşu ölçüm istasyonlarına ait enlem-boylam özellikleri IDW (Inverse Distances Weighted) ve Kriging yöntemleri ile Yöntemler ArcGIS yazılımı altında ArcMAP programı uygulanmıştır. Çalışmada 2 parametresi kullanılmıştır. Bunlar; enlem (°) boylam şe...

The alpha-1 antitrypsin (AAT) haplotype Pi*S, when inherited along with the Pi*Z haplotype to form a Pi*SZ genotype, can be associated with pulmonary emphysema in regular smokers, and less frequently with liver disease, panniculitis, and systemic vasculitis in a small percentage of people, but this connection is less well established. Since the detection of cases can allow the application of pr...

The spatial interpolation of property fields in 3D, such as the temperature, salinity, and organic content of ocean water, is an active area of research in the applied geosciences. Conventional interpolation methods have not adequately addressed anisotropy in these data. Thus, in our research we considered two interpolation methods based on a triangular prism volume element, as a triangular pri...

Diagnosis of soil salinity and characterizing its spatial variability both vertically and horizontally are needed to establish control measures in irrigated agriculture. In this regard, it is essential that salinity development in varying soil depths be known temporally and spatially. Apparent soil electrical conductivity, measured by electromagnetic induction instruments, has been widely used ...
