A Comparative Study of Immunohistochemical Expression of Moesin, Cytokeratin 14 andMMP7 in Oral Squamous Cell Carcinoma and Oral Verrucous Carcinoma
...Show More Authors

Background: Squamous cell carcinoma (SCC) is the most prevalent malignant neoplasm of the oral cavity that exhibits certain histological variations. Verrucous carcinoma (VC) is an uncommon exophytic low-grade well-differentiated variant of SCC. Cellular differentiation and morphology play important roles in cell functions and maintenance of structural integrity .As the cancer is a malignant process in which disorder of the cell growth and behavior occurs, such changes may differ in different tumor types and within different grades of the same tumor. Materials and Methods:Forty two formalin – fixed, paraffin – embedded tissue blocks were included in this study (30 blocks were diagnosed as OSCC and 12 blocks were diagnosed as OVC). An immunohistochemical staining was performed using anti moesin, anti CK14 and anti MMP7 monoclonal antibodies. Results: Moesinimmunoreactivity was recognized in all the studied groups with predominant cytoplasmic expression in OSCC & membranous expression in OVC. No difference was noticed between 2 studied groups &between different grades of OSCC. Cytokeratin 14 positivity was noticed in all studied groups with significant difference between OSCC&OVC (p=0.012) & there was a significant difference between the different grade of OSCC (p=0.047). MMP7 expression was observed in the all studied groups with predominant cytoplasmic pattern in OSCC & nuclear pattern in OVC. No difference was found between the 2studied groups &between the different grades of SCC. A Strong positive linear correlation between MMP7&CK14 was noticed. Conclusion: Verrucous carcinoma has a specific pattern for moesin and MMP7 that differs from OSCC, however; the difference is not significant. CK14 immunoreactivity indicated a significant difference in the degree of cellular differentiation between OSCC &OVC.

Impact of a Proposed Strategy According to Luria’s Model in Realistic Thinking and Achievement in Mathematics
...Show More Authors

The research aims to find the impact of a proposed strategy according to the Luria model on realistic thinking among fifth-class scientific students and their achievement in mathematics. To achieve it, the experimental research method and the quasi-experimental design were used for two equal groups, one of them is a control group taught in traditional way and the other is an experimental one taught according to strategy based on Luria model. The research community represents the students of the fifth scientific class from the General Directorate of Education of Karkh First. The research sample (40) students were deliberately chosen and distributed equally between the two groups after making sure that they were equals in their previo

In This research a Spectroscopic complement and Thermodynamic properties for molecule PO2 were studied . That included a calculation of potential energy . From the curve of total energy for molecule at equilibrium distance , for bond (P-O), the degenerated of bond energy was (4.332eV) instate of the vibration modes of ( PO2 ) molecule and frequency that was found active in IR spectra because variable inpolarization and dipole moment for molecule. Also we calculate some thermodynamic parameters of ( PO2 ) such as heat of formation , enthalpy , heat Of capacity , entropy and gibb's free energy Were ( -54.16 kcal/mol , 2366.45 kcal/mol , 10.06 kcal /k/mol , 59.52 k

STRATEGIC DECISION MAKING APPROACHES AND ITS INFLUENCE AT EFFICIENCY OF SERIVICE MARKETING: AN APPLIED STUDY IN GENERAL DIRECTORATE OF TRAFFIC.: STRATEGIC DECISION MAKING APPROACHES AND ITS INFLUENCE AT EFFICIENCY OF SERIVICE MARKETING: AN APPLIED STUDY IN GENERAL DIRECTORATE OF TRAFFIC.
...Show More Authors

Strategic decision making is considered one of the important processes for senior management in contemporary business organizations and service organizations due to the properties of the service such as intangibility, concomitance and mortality. Decision-making has three approaches according to the opinions of most of the writers and researchers in the administrative area: an analytical approach, intuitive approach and behavioral approach. This research is trying to discover the nature of the relationship in terms of the link between the impact of each of these approaches and efficiency of marketing services by selecting an intentional sample of 58 researches from the Directorate General of Traffic, one of the Iraqi Interior Ministry ins

Cooling and Heating a Greenhouse in Baghdad by a Solar Assisted Desiccant System
...Show More Authors

Modeling the microclimate of a greenhouse located in Baghdad under its weather conditions to calculate the heating and cooling loads by computer simulation. Solar collectors with a V-corrugated absorber plate and an auxiliary heat source were used as a heating system. A rotary silica gel desiccant dehumidifier, a sensible heat exchanger, and an evaporative cooler were added to the collectors to form an open-cycle solar assisted desiccant cooling system. A dynamic model was adopted to predict the inside air and the soil surface temperatures of the greenhouse. These temperatures are used to predict the greenhouse heating and cooling loads through an energy balance method which takes into account the soil heat gain. This is not included in

The Extent to Which Public Relations Departments in Government Institutions Use Artificial Intelligence Applications in Their Communication Activities: A Field Study
...Show More Authors

Abstract This study explores the extent to which public relations (PR) departments within Traqj governmental institutions are integrating artificial intelligence (AI) applications into their communication activities. The research adresses the growing importanc of AI in enhancing administrative efficieney, communication transparency, and stakeholder engagement. Adopting a descriptive research design, the study relied on an electtonic questionnaire distributed to PR profesionals across various ministries and government bodies, collecting 100 valid responses. The indings reveal that while younger PR practitioners are actively embracing AI, older employees show limited engagement. Most participants acquired AI-related skills through self- learn

DFT + U and ab initio atomistic thermodynamics approache for mixed transitional metallic oxides: A case study of CoCu 2 O 3 surface terminations
...Show More Authors

This study develops a systematic density functional theory alongside on-site Coulomb interaction correction (DFT + U) and ab initio atomistic thermodynamics approachs for ternary (or mixed transitional metal oxides), expressed in three reservoirs. As a case study, among notable multiple metal oxides, synthesized CoCu2O3 exhibits favourable properties towards applications in solar, thermal and catalytic processes. This progressive contribution applies DFT + U and atomistic thermodynamic approaches to examine the structure and relative stability of CoCu2O3 surfaces. Twenty-five surfaces along the [001], [010], [100], [011], [101], [110] and [111] low-Miller-indices, with varying surface-termination configurations were selected in this study.
