Background: Tooth extraction is one of the most commonly performed procedures in dentistry. It is usually a traumatic process often resulting in immediate destruction and loss of alveolar bone and surrounding soft tissues. Various instruments have been described to perform atraumatic extractions which can prevent damage to the paradental structures. The physics forceps is one of those innovations in dental extraction technologies that claim to provide an efficient means for atraumatic dental extractions. Materials and method: A randomized clinical trial was conducted to compare the physics forceps with the conventional forceps for the removal of 28 mandibular single rooted teeth under the following parameters: incidence of crown, root, buccal alveolar bone fracture, the incidence of gingival tear and time needed for extraction. The samples were assigned randomly into two groups according to the computer based randomization software, into a control group (A) and study group (B). The control group was subjected to the surgical extraction procedure using the conventional forceps while the study group was subjected to the surgical extraction procedure using the physics forceps. Results: results showed that the time required for extraction using the physics forceps was (mean 0.385 min.), which was significantly lesser as compared with that of conventional forceps (mean 3.971 min.) (P=0.011), buccal bone fracture occurred in 4 out of 14 cases (28.57%) using the conventional forceps while it did not occur with the use of the physics forceps (0.00%), crown fracture occurred in 3 cases using the conventional forceps (21.43%), while it did not occur with the use of the physics forceps (0.00%), root fracture occurred in 1 case using the physics forceps (3.57%), while it did not occur with the use of the conventional forceps (0.00%). As for the gingival tear, it occurred in 7 cases using the conventional forceps (50.00%), while it did not occur with the use of the physics forceps (0.00%) which was highly significant (P=0.006). Conclusions: the use of physics forceps maintains the integrity of gingiva and surrounding periodontium. So extractions using physics forceps are less invasive over conventional forceps and can be considered as a reliable method for extraction requiring significantly less comparative intraoperative time.
We examine 10 hypothetical patients suffering from some of the symptoms of COVID 19 (modified) using topological concepts on topological spaces created from equality and similarity interactions and our information system. This is determined by the degree of accuracy obtained by weighing the value of the lower and upper figures. In practice, this approach has become clearer.
In this study, the researcher aimed to define and measure the relevance and effect of the governmental organizations in complying with Iraqi Ministry of Transportation's requirements towards achieving the social responsibility, embodied in the ten commandments of the United Nations Findings displayed the availability of realization regarding organization managers towards social responsibility with their various capabilities and tendencies in relation with the representing entries of those Ten Commandments.The study showed the relation between the effectiveness of those organizations and dimensions of the ten commandments of social responsibility, with the existence of a significant effect for the said effectiveness on achiev

The aim of the study is to study the quality of services in a sample of the municipalities of Baghdad governorate and identify the deviations in their operations and provide solutions to address the causes of deviations. The research field aims at the same activity related to municipal services and their quality and analysis using some tools for continuous improvement to identify the authorities responsible for the delay and quality of services. In the future, the importance of research is shown by the use of these tools and their use and their application to the data of the directorates (sample of the study) to diagnose and treat problems, especially that they include statistical methods that are clear and easy to understand the

She wrote her book Incidents in the Life of a Slave Girl: Written by Herself, (1842) to reflect upon the exploitation of the black people and the need to change the hierarchal attitude that governs white/black relations. She was engaged in many abolitionist events and her anti-slavery approach appeared clearly in her writings. She shares Du Bios ideas about freedom and emancipation and the need for a political and cultural change.

Firstly, we define the KU-graph which is determined by all the elements of commutative KU-algebra as vertices. Secondly, the graph of equivalence classes of commutative KU-algebra is studied and several examples are presented. Also, by using the definition of graph folding, we prove that the graph of equivalence classes and the graph folding of commutative KU-algebra are the same, where the graph is complete bipartite graph.
