In the present study, male albino mice were used to estimate the effects of titanium dioxide nanoparticles (TiO2) suspension used in two doses (150, 600 mg/kg) through intraperitoneal route. The results revealed a significant difference (p≤0.05) among the control and experimental groups in all haematological parameters, including a significant increase in White Blood Cell (W.B.C) count, Mean Cell Volume (MCV), Mean Cell Haemoglobin Concentration (MCHC), and Mean Cell Haemoglobin (MCH). Also, the results showed a significant decrease in Red Blood Cell (R.B.C.) count and Haemoglobin (Hb). Biochemical tests included AST and ALT and showed a significant elevation in all exposed groups, while ALP was decreased after fourteen and thirty days of exposure. In the case of kidney function, creatinine was increased in all groups during the experiment, whereas uric acid was increase in many cases and recorded the highest mean value after fourteen days of exposure to the dose of 150mg/kg and after thirty days of exposure to the dose of 600mg/kg. Level of urea was decreased in the fourteen-days and thirty-days treatment groups, while its mean values after using the two doses did not change significantly after one day. Cholesterol level was decreased after thirty days, recording the lowest mean value at 600mg/kg, whereas the level of HDL was significantly (p≤0.05) decreased and that of LDL significantly increased. The study of bioaccumulation demonstrated that the TiO2 NPs are accumulated mainly in the spleen, followed by the liver and kidneys of mice, respectively. Also, the doses used caused histological alterations such as changes in the congested dilated portal tract, with heavy inflammatory cells infiltration and dilated central venule in the liver, along with glomerular congestion, tubular congestion, atrophy, chronic inflammatory cells infiltration, and dilated tubules with flat atrophied lining epithelium in the kidneys. The histologic alterations observed may represent an indication of different degrees of organ injury due to the toxicity of TiO2 NPs, resulting in an inability to deal with accumulated residues from the metabolic and structural disturbances caused by these nanoparticles.
Most real-life situations need some sort of approximation to fit mathematical models. The beauty of using topology in approximation is achieved via obtaining approximation for qualitative subgraphs without coding or using assumption. The aim of this paper is to apply near concepts in the -closure approximation spaces. The basic notions of near approximations are introduced and sufficiently illustrated. Near approximations are considered as mathematical tools to modify the approximations of graphs. Moreover, proved results, examples, and counterexamples are provided.
In the field of research in the investment of gas fields, this requires that we first look at the center of the contracting parties in terms of the guarantee means granted to them under the contract, which constitute a means of safety and motivation to enter as major parties in the investment project. In turn, we will discuss the minimum guarantees, which are the most important guarantees granted to each of the two parties to the contract, namely the national party and the investor.
Justice is a human values that heavenly religions urged, and made her the fundamentals of individual and social and political life, in Allah almighty sent justice messengers, and sent down his books,as the Earth and the heavens with justice, it is a legal system in which a person takes his dues, which protect the rights of the individual And punish him when committing mistakes, so all religions to achieve chiefly Christianity, the Bible that Allah almighty qualities of Justice, and it is not affected by love or hate, and no factors or percentages, but granted to all who are on earth that despite money and prestige, or what was between them. Of affection or no matter, as well as injustice, whether unjustly or self for others, especially the
... Show MoreHumility is assign of the Purity of the soul and safety of the heart from the disease of pride and arrogance. It represents an important side of the formation of man's character and his behavior since it calls for love, intimacy and connection and a means to free the heart from the chains of envy and grudge. The word Humility (humbleness) appeared in the holy bible in many places. A accordingly, Christianity urged for sticking to it by its followers. The study aims at showing the meaning of humbleness, its importance and example of the humbleness of Jesus Christ (Peace be upon him) under the title (humbleness in Christianity/A Descriptions study). The paper falls into an introduction and three sections. The introduction talks about the mean

Play constitutes a significant means for children to figure out the world around. Play helps children to have a healthy brain that increase their creativity via developing emotional, cognitive, physical strength. Thus, the current research aims to identify the role of play in psychological development of children. The findings of study revealed that play develops children’s cognitive, emotional abilities and enhances their self-confidence. Play forms a major approach for learning that promotes children to get rid of stress. Additionally, it supports language development of children
