Abstract: Algeria is vast country which presents several bioclimatic stages and agro-ecological which supports the production, a multitude of agricultural produce. The steppe forms integral part of this extent of which importance is hardly lower than the other areas. Hodna is in the middle of the Algerian steppe, it is a relatively degraded basin of 25000 km2, consequence of a prolonged dryness and an overgrazing. This study is devoted to the diagnosis of the current location of the perimeter of the plain of M sila which is in the Western Northern zone of the basin of Hodna on a geographical area of a surface of 780 km2. The population is dense in North with the existence of an urban centre and a relatively populated rural area in the South, the population is less dense with relatively distant urban centers. The plain of M sila receives an annual rain average of 213.20 mm, the rains of Autumn are sometimes torrential which gives birth to abrupt risings and devastators. The thermal amplitude of the station of M sila is of 35.02°C. The dominant winds are the wind of West known as Dahraoui, wind of North known as Bahri and the Sirocco which is hot wind and blowing dryness of the South and which blocks the development of the cultures by accentuating their drying. The diagram ombrothermic allows to identify existence; only one period of 3 months dryness, the end of May at the end of August. The zone study is made up an alluvial plain of low altitudes, <400 m made of alluvial deposits of quaternary (alluvia, clays and sands) with a soft slope <3%, pertaining to steppe bioclimatic stage. The ground is not very advanced of alluvial contribution with limono-argillaceous texture rather deep. Occupation of the ground by the vegetation is diversified, one noted a broad diversity of the agricultural activity which settled current the last years which exceeds 54,700 ha, the fallow exceed half of agricultural surfaces during the agricultural partner 2009/2010, the cultivation of cereals which occupies 36% of the grounds followed by the fodder cultures and fruit-bearing arboriculture at a rate of 5 and 4%, respectively. The exploration of the not cultivated plant species of the area study, counts 550 tax relating to the steppe communities with Chott El Hodna. One finds there many species endemic with the area of Hodna such as Saccocalyx saturoides, Arnebia decumbens and Linaria laxiflora that one finds only in this area. As well as endemic species North African such as Muricaria prostrata, Loncophora capiomontiana, Rhanterium suaveolens, Stippa tenacissima L., Artimisia herba alba, Anabasis oropediorum L., Salsola vermiculata L., Atriplex halimus and Salicornia arabica L. The zone of study, like the majority of the steppe zones is with vocation agropastorale with manpower of the ovine breeding bordering the 130.000. The zone study belongs to the large catchment area of Chott El Hodna, characterized by a very dense hydrographic network where the rivers take their sources i

Zbornik Radova Vizantolo?kog Instituta , 2011, DOI: 10.2298/zrvi1148061k
Abstract: The paper considers the use of the title exousiastes on the newly discovered seal of Constantine Bodin. It analyses the meaning and use of this title in the sources of a diplomatic character of the 10th century, as well as its use in the 11th century sources. The question is posed why this title was used on Bodin’s seal instead of the title archon, which had been used for former Serbian rulers, as well as whether this phenomenon had any connection to the fact that Serbian rulers, beginning at the end of the rule of Bodin’s father Michael, used the title of king.

Salim Kouloughli, Salah Kanfoud
Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.51006
Abstract: Constantine, with a population of 480,000 and containing 90,000 households, generated 164,250 tons of solid waste in 2015 in which domestic waste is the primary source. The aim of this study was to assess the situation of municipal solid-waste (MSW) management in Constantine. Actually, the collection and transportation of solid waste is managed by the municipality, with a small participation of the private sector. More than 90% of the municipality solid waste is disposed and treated in an environmentally sound manner (landfill). Unfortunately, there is a poor culture with respect to the 3R principles (reduce, reuse, recycle) in Constantine leading to a rapid growth of waste generation which has overwhelmed the capacity of the already saturated available landfill. There remain important challenges in solid waste management for the municipal authorities in Constantine which include: the proper management of the financial resources, public education aimed at reduction and separating household waste and optimizing the existing collection system.

Agricultural Journal , 2013, DOI: 10.3923/aj.2013.26.31
Abstract: Plain M'sila which covers an area of 780 km2 is characterized by an arid climate with very diverse natural resources like agriculture such as cereals and tree crops or natural like steppe species example stippa tenacissima L., and Artimisia herba alba and a sheep herd size large which is around 130 heads. Unfortunately, this wealth is subject to various constraints that hamper its proper management which are orders of ecological, agronomic, economic and social. To overcome these limitations of remedies are recommended for each factor. From an ecological perspective, it is recommended to do some practical steps; such as, setting the ground on both sides of El-Ksob River, purification of polluted waters of the dam, installed a sewage system in the living spaces of the area North Western Basin Hodna and finally preserve apricot orchards avoiding intercropping and in the distance of planting and the installation of windbreaks. The agronomic factor, it is very strategic need to improve the genetic diversity of different crops by increasing the number of adapted varieties, cultivars multiply endangered, expand irrigated areas and rehabilitating old orchards and fields, modernize farming practices and install an effective drainage system. For the economic side, we need fertilizers pesticides and fertilizers are carried to the farmers and at decent prices. Socially, more interventions are ground to suggest as the opening track inside the orchards and fields, halt urbanization at the expense of cultivated areas, the problem of land and then encourage young people has practiced this noble profession.
Aspects of reception of classical heritage in biography of despot Stefan Lazarevi of Constantine the Philosopher  [PDF]

Zbornik Radova Vizantolo?kog Instituta , 2011, DOI: 10.2298/zrvi1148287r
Abstract: The reception of the classical book heritage in the Biography of Despot Stefan Lazarevi of Constantine the Philosopher (of Kostenec) is noticed through the conspicuous reminiscences on classical antiquity, but it is also manifested through the use of artistic procedures of classical literature and the author’s high estimate of the accomplishment of pre-Christian Greek thought. In the first two types of classicism Constantine surpasses other medieval Serbian writers, while in the third he is unique among them, so his relying on classical tradition in this work is the result both of literary conventions caused by the choice of the genre of secular biography and of his belonging to the most liberal section of medieval Christian intellectuals.

Abstract: Mediterranean large lakes play an important role in providing a range of ecosystem functions and supporting biodiversity. The conservation and management of these lakes require more detailed knowledge of their ecology and environment-vegetation relationships. Chotts are probably the most poorly understood lake ecosystems. Chott Zehrez (Djelfa) as a large, shallow lake ecosystem in Algerian steppes, where wetlands are important part of their productivity. Despite the status of chott Zehrez lake as a Ramsar site, the main threat to its conservation is the private nature of surrounding land holdings in addition to the lack of knowledge and awareness by the local population of the importance of lake ecosystems. A wealth of halophytic flora exists which can be exploited for an array of uses like fodder, fuel wood, oilseed, medicines, landscaping, and environment conservation through carbon sequestration. A total 112 species belonging to 26 families and 39 genera were recorded. The sabkha flora includes 9 endangered and endemic species such as Avena bromoides, Cutandia divaricata, Herniaria mauritanica and Salicornia arabica. In this paper we mainly discussed characteristics and importance of Chott Zehrez lake ecosystem, its vegetation potentialities and economic usages will be also presented and discussed. Finally conservation strategy and restoration of this ecosystem are suggested.
Analysis of the essential oil of Ferula communis L. from Constantine, Algeria  [PDF]
International Journal of Medicinal and Aromatic Plants , 2011,
Abstract: The essential oil obtained by hydrodistillation of fresh aerial parts of Ferula communis L. (Apiaceae), growing in Constantine (North Eastern Algerian), was analyzed by GC and GC/MS. Eighteen compounds were characterized representing 93.3% of the essential oil mainly represented by myrcene (52.5 %), α-pinene (20.9%) and, β -Phellandrene (7.7%). β -Phellandrene seems to be exclusive to the present essential oil as a main component.

Abstract: Les objectifs de notre contribution reposent sur deux axes méthodologiques précis : proposer une lecture critique des sources arabes et offrir un tableau précis des terroirs du Hodna occidental, région située entre la Kabylie maritime et les zones désertiques du Maghreb central à l'époque médiévale. Dans un premier temps, nous concentrerons nos efforts sur les lieux d'activités des communautés rurales afin d'établir un inventaire des diverses structures de peuplement. Dans une deuxième partie, il sera question des principaux aspects de l'organisation tribale comme moteur du peuplement rural dans le Hodna occidental avec la présence fondamentale de groupes arabes, tribus berbères et autres étrangers . Enfin dans une troisième et dernière étape, nous essaierons de dresser un tableau des paysages agraires et des productions agricoles en mettant l'accent notamment sur la gestion des espaces agricoles. The aim of our contribution is based on two methodological points : to propose a critical reading of the Arabic sources and to give a precise picture of the soils in the western Hodna which is located between the maritim area of the Kabylie and the desert zones of the medieval central Maghreb. In a first time, we concentrate our efforts on the places of activities by the rural comunities for establishing a survey of the different settlement's structures. In a second chapter, we deal with the question of main aspects of the tribal organization as motor of the rural settlement in the western Hodna with a fondamental presence of Arab's groups, Berber's tribes and others foreigners . At last, in a third stage, we try to draw up a picture of the rural landscapes and the farm productions puting the emphasis mainly on the management of the farm spaces..
Using a GIS to Assessment the Load-Carrying Capacity of Soil Case of Berhoum Area, Hodna Basin, (Eastern Algeria)  [PDF]

Journal of Geographic Information System (JGIS) , 2013, DOI: 10.4236/jgis.2013.55046
Abstract: The concept of load-carrying capacity of the soil can be evaluated by two main components: permissible stress and permissible depth; and therefore, running it begins its assessment that allows an outline of exploitation. Nevertheless, the assessment of the load-carrying capacity made the object of several works of research and many models, based on the multi-criteria analysis, have been established. This work examines the contribution of GIS approach to assessment load-carrying capacity of the soil. This one has been finished in two practicums: 1) Assessment of the capacity of soil by a multi-criteria approach, using the Weighted Sum Model (WSM); 2) It brought to use the GIS approach to evaluate and spatialize degree of soil bearing stresses resulting from the buildings, as well as load distribution. The method has been applied to the Berhoum area of Hodna Basin, in eastern Algeria, where each is characterized by its various natural properties and density of equipment. Final results are better in the classification of the degree of load-carrying capacity possible in each site. This results in allowing exploiters to program their optimal designs for the rational management of the area.
