Two field experiments were conducted during the spring seasons of 2000,2001.The aim was to study the effect of hardening to drought tolerance on moisture percentage in root and stem of sunflower plant during growth stages . Asplit-split plots design was used with three replications.The main plots included irrigation treatments:irrigation to100%(full irrigation),75and50%of available soil water.The sub plots were the cultivars Euroflor and Flame.The sub-sub plots represented four seed soaking treatments :Control(unsoaked),soaking in water ,Paclobutrazol solution(250ppm),and Pix solution(500ppm). The soaking continued for 24 hours then seeds were dried at room temperature until they regained their original weight. Amount of water for each irrigation were calculated to satisfy water depletion in soil using a neutron meter. . Results indicated that stress at 800 Kp reduced moisture percentage in the root by 15.96% compared with full irrigation after86 days from planting,and in the stem by 9.64 and 11.99%compared with full irrigation and stress 600 Kp, respectively after 72 days from planting in the season 2001.Also stress 600 Kp reduced moisture percentage in the root after 58 days from planting by 5.81 and 5.97% compared with full irrigation and stress 800 Kp as a mean of seasons. Euroflor was superior over Flame after30 days from planting in the moisture percentage of its roots by 6.78 in the season of 2000 and by 3.10% as a mean of seasons..While Flame was superior in the moisture percentage of its stems by 4.62 and 2.51% after 58 days from planting in the season of 2000 and as a mean of seasons, respectively.Unsoaked treatment gave highest moisture percentage in the root, the percentage of increase reached to 5.05 and 9.63% than soaking in water and paclobutrazol after 30 days from planting and by 11.43 and 10.65% than soaked in water and pix solution after 86 days from planting as a mean of seasons. soaking in paclobutrazol solution decreased moisture percentage in the stem after 30 days from planting by 4.43 and 8.31% in the season 2000 and by 2.82 and 3.23% as a mean of seasons compared with soaking in water and pix solution , respectively. On the other hand paclobutrazol increased the percentage of moisture in the stems during the next stages of growth. The study suggest that it could improve water relations specially during the stages which increased water requirement (flowering and seeds filling), and increased drought tolerance by soaking the seeds presowing in water or plant growth regulators
Abstract—The upper limb amputation exerts a significant burden on the amputee, limiting their ability to perform everyday activities, and degrading their quality of life. Amputee patients’ quality of life can be improved if they have natural control over their prosthetic hands. Among the biological signals, most commonly used to predict upper limb motor intentions, surface electromyography (sEMG), and axial acceleration sensor signals are essential components of shoulder-level upper limb prosthetic hand control systems. In this work, a pattern recognition system is proposed to create a plan for categorizing high-level upper limb prostheses in seven various types of shoulder girdle motions. Thus, combining seven feature groups, w

In this paper, phrasal verbs were classified into subgroups according to their syntactic and semantic characteristics. After giving a survey of literature written on the meaning and definition of phrasal verbs, two sections have been devoted to tackle the most important issues in this category of English verbs. Section one sheds light on the basic definitions of the term ‘phrasal verb’ which are, according to the researcher’s point of view, sufficient to cover the area of the study. In addition, it studies the number and the importance of phrasal verbs in English. Section two deals with the syntactic and semantic features of Engli

Using several neologisms as an example, the article shows both the possibilities of Internet word-making process and the possibilities of studying a newly established work through Internet communication. The words selected for analysis can be attributed to the keywords of the current time. (In particular, the words included in the list of "Words of 2019") there are number of words formed by the suffix method, which is the traditional method of the Russian word formation. A negation of these words is usually made thro

However, because only the 12-o’clock position proved to be a nerve-free zone, dorsal plication at the 12-o’clock position can be advocated.
Objectives: To evaluate tunica albuginea plication with and without neurovascular bundle mobilization in patients with ventral penile curvature. Type of the study: A prospective study.
Methods: A 34 patients with a mean age of (4.8 ± 0.54) years, Who still
Los nombres propios nombran a un ser o a un objeto, distinguiéndolo de los demás seres de su misma clase, se escriben siempre con letra mayúscula a principio de palabra. Los lingüistas hacen mayor hincapié en las divergencias de referencia, entre nombres propios y nombres comunes. Así, suele decirse que el sustantivo propio no tiene como referente ningún concepto. El asunto de la traducción de los nombres propios parecería una cuestión de gusto personal del traductor pero vemos también que en algunas épocas es más frecuente traducirlos, y en otras, por el contrario, se prefiere dejar esos nombres en su forma original, tal vez con algunas adaptaciones ortográficas. Parecería entonces cuestión de modas. Pero, eviden
