The wetland of Naâma situated in the arid region of Alegria offers an important fauna and flora diversity due to its geographical location it constitutes the main resting place in North Africa for migratory birds. Insects are used as bioindicators, due to their sensitivity to environmental conditions which, because of their ecological peculiarities, gives information on the characteristics of terrestrial and aquatic environments. The aim of this study is to know and specify the entomofauna bio-indicator of the quality of the aquatic environment of the wetland Naâma (SW Algeria). The study carried out in the wetland from September 2017 to September 2020. Benthic insects were sampled according to the IBGN protocol (Standard Global Biological Index). Study and statistical analysis of insects communities was based by the use of the structural and statistical index, Correspondence factor analysis (CFA), and The ascending hierarchical classification (C.H.A). The results show that the collected insect 51 species, belong to 9 orders, The Coleoptera order is the most represented with 11 species, followed by the Odonata with six species, Lepidoptera ranks third with five species followed by Diptera with 03 species. The various indicators used, namely the specific richness (51 species), the Shannon index (1.01 bits), and fairness (0.56) show that this environment is characterized by significant fauna biodiversity. The study of the hydro-biological quality of the water courses of this site, assessed by the IBGN method showed a good hydro-biological quality with moderate pollution (IBGN = 14). This pollution is precisely marked by the requirement of Ephemeroptera and the disappearance of Plecoptera. These results lay the foundation for any biomonitoring action of the ecological quality of the waters of this wetland.

In Ho Chi Minh City (HCMC, Vietnam), there is now an urgent need for evaluating access to parks in an effort to ensure better planning within the context of rapid and increasingly privatized urbanization. In this article, we analyze the provision and accessibility to parks in HCMC. To achieve this, the information gathered was then integrated into the geographical information systems (GISs). Based on an Ascending Hierarchical Classification, we were able to identify five different types ranging in their intrinsic characteristics. The accessibility measurements calculated in the GISs show that communities are located an average of at least 879 meters away from parks, which is a relatively short distance. Children have a level of accessibility comparable to that of the overall population. Accessibility also seems to vary greatly throughout the City—populations residing in central districts (planned before 1996) enjoy better accessibility compared to those in peripheral neighborhoods (planned after 1996). Parks located in areas planned between 1996 and 2002 are the least accessible, followed by parks in areas planned after 2003. Our findings suggest possible approaches that could be used to help ensure the quality of parks and their spatial accessibility.

Abstract. The date palm is a monocotyledon thermophilic desert plant, in Algeria grown more than 18 million trees. To have a better quality of dates for the most answered cultivars in Algeria, we can act with fertilization on the palm and these components of the leaflets and spines that affect dates quality. The three cultivars of date palms (Deglet nour-C1, Ghars-C2 and Mechdegla-C3) have been studied to estimate the relationship between leaflet and spine number and date quality. Five phenotypic traits were exploited and subjected to analysis of the principal components in ascending hierarchical classification. The results revealed that the cultivar Deglet nour scored the highest value for the parameters spine number (25) and weight of the date (8.63g), the cultivar Ghars also recorded the highest value for the parameters: number of leaflets (80) and length (4.35cm) and thickness (2.25cm) of the date. In all studied cultivars positive correlations between the length and width of the leaf – on the one side, and weight of the date – on the other, and between the width of leaf and width of the date were found.

Abstract Phyllanthus niruri L. (meniran), the member of Euphorbiaceae, is a medicinal plant that is commonly found in tropical and sub-tropical areas such as Asia, America, and China. Various factors such as environment, geographical location, harvest time, and post-harvest process can affect the quality of crude drugs produced from P. niruri. The objective of this study was to evaluate the quality of meniran herbs obtained from 15 geographical origins in East and Central Java, Indonesia using Thin Layer Chromatography (TLC) profiles analyzed by chemometrics. TLC was carried out using TLC plate Si Gel 60 GF254 as stationary phase; toluene, ethyl acetate, methanol, 85% formic acid (75:25:25:6) as mobile phase; and visualized using NP/PEG Reagent. The results showed TLC-fingerprinting combined with chemometric (PCA and CA) analyses were able to discriminate the origin of P. niruri from different geographical origins. P. niruri from 15 locations of East and Central Java Indonesia were classified into 5 groups based on their chemical similarity. The samples that are grouped in one cluster have the similar quality of chemical compounds, while the samples in different clusters also have different qualities.

The article considers the geo-ecological situation of the Ili basin. The definition of the physical and geographical location, topography, soil and vegetation of the region was given. It was determined that the management of the efficient use of water resources in the Ili river basin depends primarily on the water resources of the rivers entering the basin and the level of Lake Balkhash. Factors determining the spring flow of the Ili River are shown. Due to the development of the middle reaches of the Ili River, the whole river ecosystem, rice fields and shangel massifs, excessive use of mineral fertilizers and chemicals has led to a decrease in the quality of river water. In addition to the shortage of water resources, anthropogenic measures related to the rapid development of agriculture affect the quality of river water. Physical and chemical studies of water samples taken from the Ili River were carried out. It was clearly observed that the content of trace elements of zinc, lead and iron in water is higher than the approved maximum allowable concentration. According to the results of the study, the effect of micronutrients on the human body was considered.

Background Two endemic lycophyte species Isoetes cangae and Isoetes serracarajensis have been recently described in the State of Pará in the Amazon forest located in northern Brazil. Isoetes L. has survived through three mass extinctions. Plants are considered small-sized, heterosporous, and can display a great diversity of physiological adaptations to different environments. Thus, the current study aimed to estimate the genetic variation of the populations of I. cangae and I. serracarajensis to generate information about their different mechanisms for survival at the same geographical location that could point to different reproductive, adaptative and dispersal strategies and should be considered for effective conservation strategies. Methods The genetic diversity and population structure of I. cangae and I. serracarajensis were investigated using Inter Simple Sequence Repeat (ISSR) molecular markers. Total genomic DNA was isolated, and the genetic diversity parameters were calculated. Results The sixteen primers produced 115 reproducible bands, 87% of which were polymorphic. A high level of polymorphic loci (81.74% and 68.48%) and a high Shannon index (Sh = 0.376 and 0.289) were observed for I. cangae and I. serracarajensis, respectively. The coefficient of genetic differentiation between population areas (GST) showed a higher value in I. serracarajensis (0.5440). Gene flow was higher in I. cangae (1.715) and lower in I. serracarajensis populations (0.419). Overall, the results further show that I. serracarajensis and I. cangae are two species with considerable genetic variation and that these differences may reflect their habitats and modes of reproduction. These results should be considered in the development of effective conservation strategies for both species.

The process of positioning a region is one of the most important tools for attracting investment to a territory. In turn, the methods of work of the human health management system, contributing to the improvement of the quality of life of the population. However, effective tools for positioning the region, which take into account the geographical location, recreational conditions of the territory, the available opportunities, its cultural, national and ethnic identification, as well as differences, have not yet been proposed. This is evidenced by the low level of investment in the regions, the weak development of the real sector of the territory's economy, the rapid decline in the living standards of most of the region's residents, and, as a consequence, the growth in the rate of population migration. Thus, the formation of tools for positioning and identification of the region, which allows you to determine their competitive advantages, is a basic prerequisite for ensuring the economic development of the territory. In modern conditions of the transfer of powers and budgets of state bodies to local governments, the positioning of the region becomes a possible condition for their competitiveness. The article discusses the interpretation of the concept of "positioning", in particular, two of its basic components are highlighted: positioning as a strategy, positioning as a set of actions. Approaches to the positioning of the brand of the region are analyzed, where the region is considered from the position of a unique phenomenon and a complex product with a wide range of properties. The signs of a successful brand are determined, the main goals of branding, assessment, classification of models and stages of positioning the region are highlighted. and also: diagnosis of the situation, formulation of the essence of the brand, a strategic plan for brand promotion. implementation of the strategic plan, assessment of the effectiveness of the formed brand.

Secure Access Control

A personal network (PN) is a network of a user’s personal devices and services, cooperating with each other independently of their geographical location to provide ubiquitous services to the user. PNs can be the producers and consumers of the services, content and resources. They can also export the subsets of their personal resources and services to other PNs. In such cases, PNs may form a group-oriented secure network called a Federation of Personal Networks (Fednet). A Fednet is a temporal, ad-hoc opportunity or purpose driven network of PNs, in which PNs collaborate with each other to share resources and services in a peer-to-peer manner. A Fednet is a pervasive and ubiquitous computing technology that enables the users to enjoy cooperation and promises exciting opportunities for different applications in various fields, such as education, healthcare, entertainment, business and emergency.In this chapter, the authors discuss PN technology expanding on the concept of Fednet. They provide example scenarios for Fednets, showing their potential impact to the quality of life of their users. Furthermore, they present the architecture and lifecycle of a Fednet. They explain the interactions of the main architectural components during its lifecycle and present a framework for the secure access control and management for a Fednet. The framework provides a controlled collaboration of PNs, where each PN controls the access to its resources and services. Finally, the authors provide a brief overview of some of the existing resource sharing group-oriented networks related to Fednets.

Abstract Equality for all genders, reflecting that gender is not a simple binary, is about individuals being able to lead their everyday lives autonomously, with their own freedom to maximize their quality of life. Indian women living an urban life appear to have access to individual and collective leisure opportunities. However, their lived experience of indoor and outdoor leisure are heterogeneous and complex. A range of sociocultural, economic and religious factors affect women's leisure choices and, especially, the freedom to enjoy outdoor leisure. Examining the complexities embedded in women's constructions and experiences of outdoor leisure may help in addressing gender inequalities at another level. This requires understanding the multi-layered complexities of Indian women's lives that are intersected by caste, class, education, financial income, geographical location and invisible sociocultural factors. Indian women's outdoor leisure experiences are deeply linked to rights, social justice, human capabilities and quality of life. In that regard, there are both similarities and differences with issues associated with women's leisure in India and Western societies. A collective effort to further research that adopts an intersectionality approach may illuminate invisible issues that women from heterogeneous contexts experience. While needed for women, such an approach may be beneficial for all genders and society in general.
