Changes in ecological vulnerability were analyzed for Northern Shaanxi, China using a geographic information system (GIS). An evaluation model was developed using a spatial principal component analysis (SPCA) model containing land use, soil erosion, topography, climate, vegetation and social economy variables. Using this model, an ecological vulnerability index was computed for the research reg...

many studies since 1977, in the southern coast of caspian sea revealed that the law-setback and low-lying coastal zone have been severely and increasingly impacted by rising sea-level. this rising continued until 1995. the rate of rising was nearly 13cm per year in this period (1977-1995). the general concept of setback determination is tended to introduce a buffer area between human activities...

The objective of this study was to understand the vulnerability experienced by the family of children hospitalized in a Pediatric Intensive Care Unit (PICU). The Symbolic Interactionism and the Concept of Family Vulnerability were the frameworks used to understand this experience. Qualitative Content Analysis was used. Data was collected through interviews and observation with 11 families of ch...

The integration of communication networks and the internet industrial control in Industrial Control System (ICS) increases their vulnerability to cyber attacks, causing devastating outcomes. Traditional Intrusion Detection Systems (IDS) largely rely on predefined models are trained mostly specific which means traditional IDS cannot cope with unknown attacks. Additionally, most do not consider i...

BACKGROUND Nocturia is a common cause of sleep disturbance affecting up to 40% of the adult population. OBJECTIVE This article provides a framework for the management of nocturia. Based on the frequency volume chart, nocturia can be divided into three categories: global polyuria, nocturnal polyuria and bladder storage disorders. Differentiating between these categories enables effective targe...

Pregnancy can cause several alterations in human eye function in healthy condition as well in ocular disease; these effects on the eyes are divided into three categories: physiologic alterations, ocular diseases changes already existing before the pregnancy, and pathological alterations. The present text proposes a bibliographical revision on the theme. The authors researched PubMed (MEDLINE) a...
