Background Of Natural Environment Research Articles

The relationship between the geographic environment and human health has been a long-standing focus of scientific inquiry. Sn as an essential trace element for the human body, play vital roles in individual health and may influence longevity. However, the extent to which the statistical characteristics of population longevity are associated with elemental geochemical background values at a regional scale remains an important question. Based on the geochemical survey data of Yunnan Province and Chinese census data, the article utilizes Arcgis spatial analysis and mathematical statistics to explore the relationship between ω(Sn) and regional longevity level. The results of the study show that: (1) There is a close correlation between ω(Sn) and regional longevity levels. Within Yunnan Province, regions with high ω(Sn) have higher levels of longevity index and Ultra-octogenarian Index. (2) Spearman’s correlation coefficient shows that ω(Sn) is significantly positively (P < 0.01) correlated with both the longevity index and the Ultra-octogenarian Index; Linear regression further reveals that ω(Sn) always has a significant positive influence on the longevity index. For the Ultra-octogenarian Index, although the strength of the influence of ω(Sn) is not as significant as that of the longevity index, its influence on the healthy longevity of the population cannot be ignored. At the county scale in Yunnan Province, there is a significant positive correlation between ω(Sn) and longevity index, which may be related to the exposure of Sn in the natural environmental background into the human body and thus affecting the incidence of cancer, but the biogeochemical cycling mechanism of its association with longevity still needs to be further investigated.

Self-calibration method for LaBr3 coupled with SiPM detector based on internal radiation of 138La

One of the most intriguing and still pending questions in radiobiology is to understand whether and how natural environmental background radiation has shaped Life over millions of years of evolution on Earth. Deep Underground Laboratories (DULs) represent the ideal below-background exposure facilities where to address such a question. Among the few worldwide DULs, INFN-Laboratorio Nazionale del Gran Sasso (LNGS) is one of the largest in terms of size and infrastructure. Designed and built to host neutrino and dark matter experiments, since the 1990 s the LNGS has been one of the first DULs to systematically host radiobiology experiments. Here we present the DISCOVER22 (DNA Damage and Immune System Cooperation in VEry low Radiation environment 2022) experiment recently started at LNGS. DISCOVER22 aims at investigating how the low radiation background modulates the Immune System (IS) response in in vitro and in vivo models. Underground radiobiology experiments are particularly complex and tricky to design and perform. In these studies, the accurate characterization of exposure scenarios is mandatory, but a challenging aspect is to understand how the very few ionizing tracks in the ultra-Low Radiation Environment (LRE) interact with the living matter in space and time in order to trigger different biological responses. In this Perspective, we describe these challenges and how we address them through a microdosimetric and a radiobiological approaches. We aim at linking physical microdosimetric measurements and the corresponding biological radiation responses by using radiation biophysical models that could shed light on many as yet unresolved questions.

Generation of map on natural environmental background absorbed dose rate in India

The period-oriented comparative evaluation of biodiversity conservation effectiveness is the main basis for implementing the transfer payment policy of ecological compensation. In response to the lack of such a spatial comparative assessment system, the paper proposes a method to construct the period conservation effectiveness index (PCEI) and applies it to the spatial comparative assessment of Chinese biodiversity conservation effectiveness in three periods from 1990 to 2015, while validating the rationality of the reference. The results show that (1) spatially, the biodiversity conservation effectiveness of key ecological function areas (KEFAs) in Central China and South China is better, while Southwest and Northwest are in the middle, and East China and Northeast are worse; (2) temporally, the biodiversity conservation effectiveness of KEFAs as a whole is worse from 1990 to 2000, best from 2000 to 2010, and middle from 2010 to 2015; (3) The existing reference establishment methods can reflect the spatial differences of natural environment background, which effectively support the spatial comparison assessment of biodiversity conservation effectiveness. This study constructs a spatial comparison assessment system of biodiversity conservation effectiveness within periods, which can provide a scientific basis for national and even global large-scale ecological compensation and other fund allocation methods.

Several pieces of research on the toponym of place names in Indonesia have been carried out but focus on place names on the island of Java. The limited documentation of place names makes the study of toponymy in Sumatra a must. This article aims to map the thematization of place naming on the West Coast of Sumatra Island. The research was conducted in a qualitative descriptive manner with a corpus linguistic approach. Data was collected by means of documentation, interviews, and focus group discussions. Data were analyzed by following work procedures by Miles and Huberman (2013), involving data condensation, data display, verification drawing, and Sudaryat's toponymy categorization (2009). The results showed that the toponym of place names on the West Coast of Sumatra Island reflects the relationship between humans and their natural environment. This relationship is manifested through the thematization of place names, namely: embodiment, social, and culture. The embodiment aspect includes the sub-themes of water background, topographical background, and natural environment background. The social aspects include the sub-themes of residential background, economic activity background, and building background. The cultural aspects include sub-themes of myths, folklore, and legends passed down through oral traditions.

Combined with GIS and remote sensing technology, according to the eco-environment characteristics of karst rocky desertification region, a complete ecological vulnerability evaluation index system was established. The ecological vulnerability of the research area was evaluated and analysed from three aspects, including natural environment background, population characteristics, human-land relationship, and the index weight was determined by entropy method and coefficient of variation method, and the comprehensive evaluation results were obtained by comprehensive index method. The results showed that more than 80% of the regions in the study area had reached the moderate vulnerability level, and nearly 1/6 of the regions were severely vulnerable areas, showing a significant increase in distribution from east to west. Ecological vulnerability shows a significant effect of human-land relationship. With the increase of vulnerability level, the proportion of desertification area increases significantly.

Abstract Considering the general typology of landscapes, winery landscapes are a subtype of agricultural landscapes. A winery landscape is an area in which the dominant land use or indigenous vegetation consists of extensive grapevine crops, that is, vineyards and/or areas covered by wild grapevines; where a specific wine culture has evolved, or grapes constitute an important part of the local diet. In this paper, winery landscapes are studied at two levels: typological (as a repeatable, specific type of area with precisely defined characteristic features), and regional (regional areas that are unique and individual). The authors analyze the evolution of winery landscapes over time and describe their natural and historical aspects. A wide range of factors were taken into consideration: historical and political, socio-economic, cultural and religious influences, as well as the natural environmental background. This paper aims to describe the evolution of winery landscapes in Europe and beyond by considering the Mediterranean Basin, Asia Minor, Transcaucasia, and Central Asia.

A novel natural environment background model for Monte Carlo simulation and its application in the simulation of anticoincidence measurement

The paper comprises geographic characteristics of Pieniny region which is introductory material for field classes at university level. First, localization of the region was depicted and its division into microregions. Next, particular components of natural environment i.e. geological structure, land relief, climatic conditions, water relations, soils, vegetation and fauna were characterized. In the next part, human activity was discussed, against the background of natural environment, which results in development of cultural landscapes. The presented description of Pieniny, in the paper, may be exemplary and auxiliary material for the construction of characteristics of other regions.

This paper presents a fuzzy approach of feature maps combination in saliency-based visual attention model proposed by Itti. This strategy applies fuzzy rules to combine three conspicuity maps instead of linear combination in the basic model of visual attention that does not seem reasonable biologically. In this method, in addition to bottom-up features, top-down cues are also considered in the model. As fuzzy rules are designed using target mask information, top-down characteristics of the target are considered helping the model to make the target more conspicuous in the final saliency map. This can be applied in further processing such as object detection and recognition application. The experimental results show the effectiveness of our new fuzzy approach in finding the target in the first hit. A database of emergency triangle in natural environment background is used in this paper to show the results. Moreover, the comparison of this fuzzy combination approach with some other combination methods also proved the priority of the approach over other combination strategies.

The vegetation recovering effect of oily soil after bioremediation was studied and contrasted with the background of natural environment in this paper. The results indicated that the vegetation productivity of oily soil after microbial remediation can be restored to its original level, but is not enough to rely on natural recovery of vegetation. The unit productivity of oily soil only through microbial remediation was obviously lower than natural background, and the biocommunity and its vertical structure were relatively simple. But the unit productivity of oily soil after phytoremediation was nearly similar to the uncontaminated soil.

Effects assessment: Boron compounds in the aquatic environment

The purpose of this paper is to identification the cultural heritage and analysis of its maintenance in Taketomi Island of Okinawa Prefecture. As a result, we found that the cultural heritage which constituted by tangible and intangible heritages are produced against the background of natural environment, history, and a wisdom of sustainable settlement and are the whole of Taketomi Island. After modernization, the traditional environment is changing and the cultural heritage management causes a problem. We made a list of the cultural heritage in order to identify the one. Base upon the verification, we drew the today's problems.

Measurements in the Levantine Sea with a seismic-type array [i.e., the high-frequency array (27 wavelengths at 348 Hz), the mid-frequency array (27 wavelengths at 175 Hz), and the low-frequency array (21 wavelengths at 58 Hz)] were found to have on average results within 1 dB of the theoretical signal gain. Observed signal gain degradations for peak-tracked and short integration times (1 min) had standard deviations from 2 to 3 dB and were caused by the combination of coherent multipaths, array shape, and array motion. The relative motion of source and receiver (5-8 kn) was an important cause of the average degradation at longer integration times (5 min). Equivalent plane wave beam noise levels were measured as a function of frequency, time, bearing, and aperture length. The beam noise level results show contributions from distant surface-ship-generated noise and natural environmental background noise. These results showed resolved distant shipping with median beam noise levels consistent with array noise gain 1-2 dB greater than the theoretical value for incoherent isotropic noise. The beam noise cumulative probability distribution function versus equivalent plane wave levels differed significantly from log-normality. Beam noise surfaces (beam noise levels versus time and bearing) show a higher density of ships for the high-frequency array when compared to the low-frequency array. Beam-to-beam cross correlations were found be sharply peaked and beam autocorrelation functions versus time showed zero crossing times on the order of 9-10 min. Significant space-time noise fade durations were observed at lower frequencies.
