Human activities have contributed to environmental degradation for decades, and ecological footprint is considered an effective tool measuring natural resource consumption. The present study explores the moderating role of green technology determine impact on health vulnerability developed developing countries from 1990 2020. long-run results are estimated by using Panel Quantile Regression mod...

In 1949 Horn and Valentine [HV] showed that if each pair of points a,b in a simple polygon P could be connected by a polygonal path of length two lying in P (such polygons are termed L-convex polygons) then through each point x in P there exists a line segment L(x) lying in P such that for every point y in P there exists a point z in L(x) with the property that the segment yz lies in P. Since t...

In this paper, we study the Chebyshev centres of bounded subsets of normed spaces and obtain a norm inequality for relative centres. In particular, we prove that if T is a remotal subset of an inner product space H, and F is a star-shaped set at a relative Chebyshev centre c of T with respect to F, then llx - qT (x)1I2 2 Ilx-cll2 + Ilc-qT (c) 112 x E F, where qT : F + T is any choice functi...

We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large area propagation in this paper. These can achieve due to twisting-induced high losses higher order modes and coupling leaky modes. A tail-like profile will appear when they couple modes, the also indicates that these carry angular momentum. Numerical simulations show octagon-shape...

In this paper, we study a new problem of finding a convex drawing of graphs with a non-convex boundary. It is proved that every triconnected plane graph whose boundary is fixed with a star-shaped polygon admits a drawing in which every inner facial cycle is drawn as a convex polygon. Such a drawing, called an inner-convex drawing, can be obtained in linear time.

In a comprehensive LMDI-STIRPAT-ARDL framework, this research investigates the residential electricity consumption (REC)-income nexus in Morocco for period 1990 to 2018. The logarithmic mean Divisia index (LMDI) results show that economic activity and intensity are leading drivers of Morocco’s REC, followed by population structure. And then, LMDI analysis was combined with stochastic impacts re...

PURPOSE The purpose of this study was to examine a J-shaped relationship between alcohol consumption and depression among the elderly in South Korea. MATERIALS AND METHODS Cross-section data were drawn from a community-based sample of individuals 60 years of age and older (n=1819). Respondents completed the Alcohol Use Disorders Intensification Test (AUDIT) and the Korean Beck Depression Inve...

The aim of this study was to examine the potential relationship between the occurrence of orthodontic root resorption and presence of dental anomalies such as tooth agenesis and pipette-shaped roots. Dental anomalies and root resorption were assessed on dental panoramic tomographs (DPT) of 88 subjects, 27 males and 61 females, mean age 28.4 (SD = 11.3 years), selected from orthodontic patients ...

Abstract As an emerging and transforming market, China has emphasized the key role of technological innovation industrial structural change in economic growth. Using a nonlinear econometric model provincial data from 2000 to 2014, this study investigates direction for driving China's From national perspective, inverted U-shaped relationship exists between progress growth, revealing need shift a...
