Maternal Recognition and Establishment of Pregnancy in Domestic Animals
(جامعة النيلين, 2011) Wagialla M. Anna'eem
Introduction Implantation is a critical step in the progress of pregnancy, during which the coceptus acquires a ﬁxed position within the uterine lumen and leads to the establishment of the placental structure. This process implies some cellular modiﬁcations of both the uterine epithelium and the trophoblast to ensure cell adhesion between the two tissues. In ruminants, the implantation process is characterized ‘by three main steps: a long pre-attachment period lasting 2-3 weeks during which the coceptus elongates considerably; an opposition stage when cellular contacts are established between the trophoblast and the uterine epithelium, and an adhesion stage which ends the process and gives rise to the cellular structure of an epithelio-chorial placenta. Acquisition of the coceptus to its designated position in the uterus underlines the need for the concepts to be recognized by its mother. - Maternal recognition of pregnancy can be considered as the interaction between the matemal unit and products of conception that signals to the mother the need to maintain pregnancy. To feature the concept of recognition of the dam to its pregnancy, forges the need to a thorough stepping over PGFQQ and factors controlling its secretion and action; oxytocin receptors and its deep implication on pregnancy; metalloproteinase's involvement in maintenance of pregnancy and all and above, the cellular interaction of the matemal and conceptual tissues. (1) Cellular Interactions During Implantation in Ruminants The blastocyst implantation involves major synchronized changes in both the uterine endometrium and the trophoblast that allow a close adhesion between the two tissues throughout pregnancy. Before any cell contact, the embryo and the uterine environment exert a mutual inﬂuence to favor the growth and the development of the coceptus as well as maintenance of pregnancy. As implantation progresses, interactions between the coceptus and the maternal compartment shift from a distant molecular dialogue by means of secreted factors , to more intimate and local exchanges mediated by cell to cell contacts.
Path coefficient Analysis for Seed Yield and Yield Components in Faba Bean (Vicia faba L.)
(جامعة النيلين, 2011) Abdel Aziz Hamid Abdel Aziz; Ahmed Ali Mohamed Osmanz
Abstract Four genotypes of faba bean (Vicia faba L.). namely: Hudeiba 72, Basabeer. Hudeiba 93 and Selaim lmproved were planted for two successive seasons 2002/03 and 2003/04 at the Demonstration Farm of the College of Agricultural Studies, Sudan University for Science and Technology. The trial was conducted to study the Path Coefficient Analysis for Seed yield and yield Components in faba bean. Statistical analysis was based on the combined data of the two seasons. The path coeﬁieient analysis was used to detemaine the direct and indirect effects of the yield components: number of pods per plant. number of seeds per pod and 100 seeds weight on seed yield

ABSTRACT This paper considers avery essential and basic issue that relates to modem linguistics. In fact, it represents pat my PHD study. This paper is based on three axps that aim to cover all that comes under the umbrella of context theory. In order to Identity the theoretical framework of the context. we should under stand its general concept which is based on the vicious of the scientists who have established theories to Identity and delay its problems, in addition to the Pioneers of the theory of context and then thoughts on which the context theory is based. The ﬁrst axis deals with the theoretical framework which includes the origin and concept. The second axis relates to the linguistic context according to ancient and contemporary linguists . This is followed by the third axis which deals with the primary context according to the ancient and contemporary linguists . It is clear that the two styles are in relegated when we the to given meaning of a singular word, we refer to the context in which it is used . This leads to the occasion on which the text is made which consolidates the afore mentioned point. I .e.. the linguistic and primary context save interrelated.
