During the period 1970-2006 the Marshes-land region was exposed to several change into many sides of vanishing steeling and growth as follow :
1- Drying this region after 1991,and re-flooded again during 2003. Many other large Marsh-land, like al-Hawaisa was dried by cutting off inlet-water fed from Iran sources .As asqunance there are transferred to different kinds of swamps ,followed by major change in the structure of the region as the rural settlement concerned. Rural settlement in this area starts new push of migration. The research did not take that in consideration in this thesis because some others took it in details in some thesis and researches. The situation of Marsh-land is getting anew face after those major changes which need an urgent action to over-come this issue . In this thesis the researcher focus on finding the relative important of variable affect those changes of rural settlement in the study area . Settlement this region was a parted tow kind :First settlement flooded big Marsh-land water while the second group of settlements found on the off shore of marsh-land .Beside that a remarkable change in (the second group).
Socio economic and environmental factors distinguished between the two groups which attract rural settlement of in the flooded area of Marsh-land were translated gradually to the second group ( on the off shore side ) . Both of those group were utile the advantage of the second group of settlement (off shore group ) were attracting the other sectored in the floodedarea for many reason :ie : Saw shore economic and environmental condition plus the high precipitins of all kind of serves, social and technical infrastructure . Researcher adept descriptive and quantities analysis for all variable collected by questioner for selective sample of household with personal interview and inventory. The thesis found very remarkable circulation and recommendation relatively given to
Cognitive radio technology is used to improve spectrum efficiency by having the cognitive radios act as secondary users to access primary frequency bands when they are not currently being used. In general conditions, cognitive secondary users are mobile nodes powered by battery and consuming power is one of the most important problem that facing cognitive networks; therefore, the power consumption is considered as a main constraint. In this paper, we study the performance of cognitive radio networks considering the sensing parameters as well as power constraint. The power constraint is integrated into the objective function named power efficiency which is a combination of the main system parameters of the cognitive network. We prove the exi

This paper examines Gloria Naylor's Mama Day (1988) that shows the mixing of African and American culture. Afro-American authors reject the Eurocentric hypothesis that slavery had ended the Afro-American cultural engagement in Africa. African Americans represent an essential fabric of American society, sharing many traditions, habits, and traits with the American society. Yet, at the same time, Naylor portrays Afro-American individuals in Mama Day as a separate unit with a unique and rich culture. These mannerisms expose a kind of resistance, appreciation to her African identity, history, and roots. A tale of a conjure woman located in Willow Springs' mythical isle, Mama Day, highlights the mystical, storytelling, and folkloristic customs.
... Show MoreThis study evaluates the advantages of employing nano-hydroxyapatite in dentistry, particularly for preventive treatment applications. Only electronically published papers were searched within this review. Sources: "PubMed" website was the only source used to search for data. 92 most relevant papers to the topic were selected, especially the original articles and review papers, from 1990 till the 1st of April 2022. The morphology of nano-hydroxyapatite, as well as the structure of its crystals, are close to that of dental enamel. As a result, hydroxyapatite can biomimetically replace the natural enamel mineral element. Keywords: remineralization of enamel, nanotechnology, nanohydroxyapatite, hypersensitivity.
Pressure ulcer (now called Pressure injury) happens when the bony prominence like the sacrum exposes to pressure for a long period and also can cause soft tissue injury. In order to prevent and cure pressure-induced wounds, continuous and attentive repositioning is necessary. Wound management begins with the identification and aggressive management of the modifiable factors, such as positioning, incontinence, spasticity, diet, devices, and medical comorbidity, which contribute to pressure injury formation. Initial interventions include washing, cleaning, and maintaining the surfaces of the wound. In certain cases, it may be sufficient to debride the non-viable or contaminated tissue; however, operational care in more severe cases

Precarity is related, states Judith Butler, with the individual’s performativity, and his ability to perform his gender role. Toni Morrison continually goes to past to retell the history of African Americans. The issues of race, gender and national identity are recurrent in her work. Reading her book Home (2012) evokes the idea of precarity and performativity since the two main characters, Frank and Cee are precarious characters that fail to perform their gender role properly, and eventually are exposed to hazard and harm. This research displays how African American

The research depends on finding alternative modern methods by which fish bodies can be preserved in a better way and for long periods after conducting some laboratory treatments on the specimens to ensure obtaining clean and clear samples suitable for diagnosis and study, in addition to keeping it in a new, lightweight and elegant form that can give three-dimensional shapes to the specimens. The final specimens were of high quality and unbreakable durability with high clarity and transparency and low manufacturing costs. This study is the first of its kind.
Background: Penetrating Neck Injuries (PNI) management represents a challenge to most surgeons in civilian trauma, in weighing selective versus mandatory exploration of all cases in different circumstances. Data are encouraging surgeons to adopt the former approach.Objectives: The study aims to assess the selective approach in our war and terror time events in Al-Yarmouk teaching hospital.Type of the study:A retrospective study. Methods: Data of patients presented to the Thoracic and Vascular ward in Al-Yarmouk teaching hospital with PNI were assessed retrospectively, from March 2013 to March 2015, and analyzed for epidemiology, mechanism of trauma, management methods, associated organ injuries, complications and mortality. Results: Amon

Show MoreBackground: The transcriptional control of various cell types, especially in the development or functioning of immune system cells involved in either promoting or inhibiting the immune response against cancer, is significantly influenced by DNA or RNA methylation. Multifaceted interconnections exist between immunological or cancer cell populations in the tumor's microenvironment (TME). TME alters the fluctuating DNA (as well as RNA) methylation sequences in these immunological cells to change their development into pro- or anti-cancer cell categories (such as T cells, which are regulatory, for instance). Objective: This review highlights the impact of DNA and RNA methylation on myeloid and lymphoid cells, unraveling their intricate
