In Algeria, 95% of the territory is subject to an arid and semi-arid climate. Agricultural production is affected by constraints related to low and irregular rain-fall as well as heavy evaporation. Barley is a very cultivated cereal crop in Algeria, it is often subjected to water stress that greatly affects production. Under these conditions, the search for techniques that allow the plant to use water more effi-ciently is necessary.\nThe objective of this work is to study the effects of water stress and seed-ling date on the growth and yield of eight early and late-winter barley genotypes in the El Hmadna region (northwestern Algeria) in semi-arid conditions. \nThe results of the morphometrical parameters show a dominance of geno-types subjected to early sowing, with plant height averages of 71,57 cm and leaf area of 22,36 cm2. The number of plants.m-2, ears.m-2 and grain yields are 186,5 plants, 392,66 ears and 27,97 Q.ha-1, respectively. Compared to early seeding, late-seeded genotypes record earliness at the heading stage of 102,89 days after sowing (DAS) and a higher thousand grain weight (TGW) of 42,52 g. The best yields are obtained with genotypes driven into early sowing. \n\nKeywords : barley, water stress, sowing date, supplemental irrigation.
Paper\'s purpose: some medicinal plants have medical properties history through richly bioactive compounds. In this study, we aimed to evaluation the antibacterial activity and phytochemical contains of these medicinal plants by used deep eutectic solvent extraction as a green solvents.\nMethods: We selected three medicinal plants and extracted by three different kinds of deep eutectic solvent.

Cancer is one of the most important reasons for death worldwide. Cancer illness is increasing at a world-wide scale, signifying that the current cancer treatments need to be revisited to improve their efficacy and the development of less adverse toxicity drugs. Therefore, there is an urgent need for the development of more effective and less toxic anticancer agents. The role of medicinal plants as a future anticancer medicine was obtained from the literature. In this review, we provide a comprehensive overview of the role of medicinal plants as a future anticancer medicine. Furthermore, we discuss the ancient’s science of medicinal plants from an Ayurveda perspective, recent findings on the anticancer activity of medicinal plants, the role of plants polyphenol or phytochemical as an antioxidant, fingerprint for new drug development, and anticancer agent. It is projected that up to four billion people (representing 80% of the world’s population) living in the third-world countries depend on herbal medicinal remedies as the main source of their health care. No science has been able to develop medicines, better than those prepared by Mother Nature especially medicinal plants. In reality, some of the most active cancer drugs available today were resulting from natural products. There are many miracle drugs in the science of medicine of the ancients which can be utilized for modern-day diseases. The phytochemicals of medicinal plants either as pure compound(s), active fraction or standardized extract are possibly important candidates for the development of novel anticancer therapeutic agents. Hence, it is paramount important to revisit the role of medicinal plants as a future anticancer medicine.
The main objective of the current study is to evaluate phytochemistry and antibacterial potential of ethanolic and aqueous extracts of P. juliflora with a view to considering their contribution to human health. Qualitative and quantitative phytochemical screening of pods and leaves was carried out. Five pathogenic bacteria were selected as recipients including four Gram-negative and one Gram-positive bacteria. Chocolate and blood agar solid media were applied for agar diffusion method. Extracellular proteins before and after treatment were measured and total protein assay was performed. In agar diffusion experiment, data showed that pod ethanolic extract (5%) was more active than the other three types of extracts. The extract elicited a decrease in the growth of Staphylococcus aureus in culture medium in comparison to the control. Both pods and leaves ethanolic extracts showed a decrease in the extracellular protein content of the tested S. aureus compared with control. TEM showed that pod ethanolic extract affected the growth of S. aureus cells. It caused severe damage in the cytoplasmic membrane and also the cell wall. The present study concluded that the pods and leaves extracts of P. juliflora possesses antibacterial potential against target bacterial type cultures.
In this article, we consider a dynamic contact problem between two electro-viscoelastic bodies with damage and adhesion. The contact is bilateral and is modeled with Tresca\'s friction law. The damage of the materials caused by elastic deformations. We derive a variational formulation for the model which is in the form of a system\ninvolving the displacement field, the electric potential and the damage. Then we provide the existence of a unique weak solution to the model.
Design and printed prototype of a compact wideband microstrip line fed patch antenna for Ku band application is presented in this paper. The proposed new E-H shaped electrically small patch antenna has been designed and analyzed by using finite element method based high frequency electromagnetic simulator and fabricated in printed circuit board (PCB). The result of the proposed antenna prototype has measured in standard far-filed rectangular shape anechoic measurement chamber. It has been clearly observed from the measured results that, 1380 MHz of -10dB return loss bandwidth with almost stable variation of radiation pattern over entire operating frequency band are achieved. The maximum gain 7.8 dBi with 89.97% average efficiency within the operating band from 17.15 GHz–18.53 GHz makes the proposed antenna suitable for Ku band applications. The parametric analysis of the proposed antenna with four different dimension of cutting slots has also been conducted in this study.

This paper presents the potential of plywood as a part of structure in high rise building in order to suppress dynamic unbalance activity. In this study, a miniature 7-storey high rise building is developed using plywood materials. In additional, a Tuned Mass Damper (TMD) control scheme is applied in order to have better harmonic absorber mounted at a bottom of the structure to prevent discomfort of sway at horizontal axis. The bottom floor of TMD is modeled as a nonlinear spring mass system and the total energy is only due to the elastic potential energy coming out from the earthquake. This TMD is obtained using Lagrange and D’Alembert method from a two degree of freedom (DOF) vibration structures.Then frequency response function (FRF) experiment was developed to analysis the responses of high-rise building in order to get the feedback response when a continuous excitation is applied at the horizontal axis of the ground structure. As a result, plywood materials are able to absorb more energy during the earthquake. Finally, with a better control scheme, the analysis shows no different at FRF but a 5 degree lower different in phase from baseline experiment.
A study was conducted to evaluate the performance of a disk harrow as a primary cultivation tool in loamy sand soil. Four plowing speeds viz. three different soils surfaces classified as low soil cone index, medium soil cone index and high soil cone index were investigated. The results show that draft force tends to increase with plowing speed and that this relationship is almost linear at speeds between 1.82 and 7.59 km/ h. Also, the results showed that draft force tends to increase with soil cone index and that this relationship was almost linear at soil cone index between 233 and 1592 kPa. The high value of the coefficient of determination recorded in the draft model equation indicated that the equation could enable anyone to predict the draft requirements of the disk harrow operating in loamy sand soil within the range of plowing speed and soil cone index used in the field.
Abstract\n In the process of criminal justice, attending the issue of children i.e. those who are in danger of victimization are of crucial importance for personal, social, economic, cultural, political etc reasons. Due to the singularity of their vulnerable conditions, they need and deserve to benefit from different kind of preventive and protective plans and measures against social, economic, physical and emotional/ psychological abuses. Hence, protecting children should be included in special laws and regulation i.e. differential criminal policies (differential protective victimology). Accordingly, the present paper is aimed at studying on the concept of “victim and children”, Why their Vulnerability, and Why children should Receive Differential Protection. Finally, it mentions some of the most important social preventive plans and measures adopted against victimization of children.\n\n Key word: children, victimization, Social Prevention, protection, differential criminal policies
Nowadays duplication forgery is the most applicable method to make tampered images. This method copies a region of an image and pasted into another part(s) of that image. There are several methods to detect forged images. Most of them can only detect those regions which are exactly pasted into another part, but in practice the copied region is scaled or rotated before pasting to achieve the best matching with surrounding.\n In this paper we propose a method to detect duplicated regions in an image using SIFT features and then using Zernik moments. By using SIFT features we can detect duplicated regions even if they scaled or rotated, but these features cannot find flat duplicated regions. Zernik moments can solve this problem; they can find flat copied regions but failed to find scaled copied regions. So combining these two methods gives an effective approach to achieve a robust detection.
