When observing a scene horizontally at a long distance in the near-infrared domain, degradations due to atmospheric turbulence often occur. In our previous work, we presented two hybrid methods to restore videos degraded by such local perturbations. These restoration algorithms take advantages of a space-time Wiener filter and a space-time regularization by the Laplacian operator. Wiener and La...

The effect of various additives such as fly ash, phosphogypsum, jaggery, lime, and polyethylene glycol on green waste composting was investigated through assessing their influence on microbial growth, enzymatic activities, organic matter degradation, bulk density, quality of finished compost including gradation test, heavy metal analysis, etc. A perusal of results showed that addition of jagger...

In the last decade, many function-approximation methods for illustration images have been proposed. However, these methods cannot process more complex full color images effectively, even when some simple regularity of color transitions such as gradations appear in images. In this paper, we propose a rigorous function-approximation method that is applicable for gradation images. This method perf...

We give the complete picture of the complexity of conjunctive query answering under (weakly-)(frontier-)guarded disjunctive existential rules, i.e., existential rules extended with disjunction, and their main subclasses, linear rules and inclusion dependencies.

Using a culturally informed risk-protective framework, the purpose of this study was to examine spiritual well-being (existential, religious) as a moderator (protective factor) in the relation between neighborhood disorder (risk factor) and parenting stress in a high-risk sample of low-socioeconomic status (SES) African American women (N = 144). These women, who were primary caregivers of child...

AIM The aim of this study was to explore relatives' existential concerns when caring for a seriously ill family member as well as to describe interventions that meet these concerns. METHODS In this integrative literature review we assessed and classified 17 papers, 12 qualitative and 5 quantitative. Literature was sought in the databases Cinahl, PubMed, Psykinfo and Web of Science in Septembe...

When a person is diagnosed with a severe disease, it seems plausible that existential questions and death anxiety are easily intensified. The aims of this study were to explore whether this is the case, to what extent patients and their next of kin experience death anxiety, and how these experiences are expressed. Following a purposive sampling technique, 20 patients with brain tumours and 15 o...

BACKGROUND AND OBJECTIVES Spiritual aspects of health-related quality of life (HRQoL) in patients with chronic kidney disease (CKD) have not been fully assessed. This study described the religious and existential dimensions of spirituality of patients with CKD, provided evidence to support construct validity of the ESRD Spiritual Beliefs Scale, and examined the relationship between constructs o...

A prominent existential concept is that elderly parents should naturally become severely ill or die before a younger person does. If the reverse should happen, it may influence the parent's existential view of life. The aim of this study was to investigate the existential issues during illness time. This was a qualitative study with in-depth interviews and was conducted in a University Hospital...

Existential threat lies at the heart of intergroup conflict, but the literature on existential concerns lacks clear conceptualization and integration. To address this problem, we offer a new conceptualization and measurement of existential threat. We establish the reliability and validity of our measure, and to illustrate its utility, we examine whether different existential threats underlie th...
