Spectral studies of some hydroxy-derivatives of anthraquinones

The u.v., visible, and i.r. spectra of several hydroxy-anthraquinones are discussed and the bands are assigned. These bands are compared with those of anthracene and anthraquinone. The band at 207 nm. is assigned to a n-sigma* transition; the bands at 252, 272, and 326 nm. are assigned by measuring spectra in solvents of various polarities. The stability constant for the 12-dihydroxyanthraquinone-ethanol complex is obtained

Optimization of Wastewater Treatment Plant Design using Process Dynamic Simulation: A Case Study from Kurdistan, Iraq

Satisfactory effluent characteristics are indispensable to evaluate the performance of any wastewater treatment plant (WWTP) design. Dynamic simulation software has a great role in pursuing this objective, in which an efficient and cost-effective design is constantly performed. In this study, a dynamic simulator sewage treatment operation analysis over time (STOAT) has been used under certain influent conditions to optimize design possibilities for modifying an existing primary WWTP College of Engineering Wastewater Treatment Plant (COEWWTP) at Erbil, Kurdistan, Iraq. The optimization was established on the basis of total suspended solids (TSS) and biochemical oxygen demand (BOD) characteristics in the effluent. Two alternative design schemes were proposed; trickling biofilter and aeration basin. In the dynamic simulation for the investigated design schemes, the predicted effluent profile showed that each of the existing and trickling biofilter processes has failed to correspond to the valid effluent limitation, whereas predicted results of the aeration basin exhibited an effluent profile that meets TSS and BOD allowable limits. Different simulation models have been implemented by STOAT to simulate treatment processes in studied design approaches: ASAL 1 model; BOD model; BOD semi-dynamic model; and SSED 1 model. This study offers an additional understanding of WWTP design and facilitates the application of dynamic simulators as tools for wastewater treatment development in Kurdistan

Exploring a paperless business administrative system (BAS) implementation in a K-12 school

The primary purpose of this qualitative study was to investigate how a paperless BAS can affect the overall performance of a school’s administrative activities. The research included direct observation, survey questionnaires, document review, and both structured and unstructured interviews. The selected school, a K-12 charter school, was an ideal candidate for this study as it allowed unrestricted access. The effects of the move to a paperless BAS were overwhelmingly positive. These effects included enabling employees to complete their resource requests more speedily and accurately. The implementation also incorporated “smart” forms that did not allow users to submit incomplete forms. Employees were able to track requests, ensuring that objectives were achieved effectively and in a timely manner. Continuous, rapid, and secure access to information allowed stakeholders to make quicker and better-informed decisions. One negative effect was that the user interface required a steep learning curve. Employees expressed concerns about the lack of transparency in the decision to go paperless. Finally, employees from all user groups expressed their desire for more in-depth and frequent training, including periodic refresher courses, not only to keep users abreast of system changes and updates, but also to allow them to continuously hone their skills using the system. Based on the survey data, several recommendations for change emerged. An illustrated system user guide would be an important tool for users. In addition, an online help function, along with a live Help Desk and IT staff, would decrease system issues and delays. Early involvement from stakeholders in the decision to move to a paperless system would improve the “buy-in” from all stakeholders. Future research could investigate whether different training programs yield different results. Additional quantitative research is needed to investigate the return on investment from going paperless. Finally, future research should address other aspects of school operations that could be made paperless

EDUCATORS’ PERCEPTIONS OF THEIR INSTRUCTIONAL LEADERSHIP STYLES AND THEIR PROBLEM SOLVING STYLES

Instructional leadership is not well-defined in the literature. The term has been used to describe the principal’s role as an instructional leader. However, principals are not the only instructional leaders. Teachers are as well. In this study, data on leadership and problem solving style were collected one time from 378 educators in K-12 school settings in the northeast of the U.S. The purpose is to provide an empirical evidence of what describes instructional leadership. The results of a 4x4x4 MANOVA indicated that there were significant differences between educators’ scores on the leadership subscales for the Orientation to Change (OC): Explorer-Developer (F(3, 290) = 8.236, p \u3c .001, partial eta squared = .079) and the Manner of Processing (MP): External-Internal (F(3, 290) = 4.597, p = .004, partial eta squared = .045) groups. The OC subgroups differed significantly in the areas of transformational leadership (F(3, 290) = 6.956, p \u3c .001, partial eta squared = .067) and passive/avoidant leadership (F(3, 290) = 4.438, p = .005, partial eta squared = .044). The MP subgroups differed significantly in the areas of transformational leadership (F(3, 290) = 3.683, p = .012, partial eta squared = .037) and passive/avoidant leadership (F(3, 290) = 3.128, p = .026, partial eta squared = .031). There were no significant differences in mean scores of all types of leadership for the Ways of Deciding (WD) group. Furthermore, there were no significant interactions between VIEW groups. All VIEW groups scored the highest on transformational leadership and the lowest on passive/avoidant leadership. Three stepwise multiple regression analyses were used to determine the extent that educators’ gender, years of teaching experience, highest degree earned, type of certificate, and scores on the problem solving styles predicted their perceptions of their leadership styles. Results indicated that the highest degree earned, educators’ preference for Orientation to Change: Explorer-Developer problem solving style, gender, and type of certificate were significant predictors of the variance in the mean scores of transformational leadership, R squared = .189, adjusted R squared = .179, F(4, 338) = 19.67, p \u3c .001. There were no significant predictors of the mean scores of transactional leadership at the Bonferroni adjusted alpha of .0125. The type of certificate was the only significant predictor of the passive/avoidant leadership subscale, R squared = .049, adjusted R squared = .046, F(1, 341) = 17.40, p \u3c .001. Data from three open-ended questions related to the participants’ perceptions of leadership and problem solving were coded and analyzed. Four common overarching themes emerged: (a) personal characteristics, (b) knowledge and experience, (c) interactions with others, and (d) setting directions. The quantitative findings were then triangulated with the qualitative results to describe constructs of instructional leadership

The relationship between Hypertension and weight status in Iraqi population

Most medical books and researches documented that increased body weight is a predisposing factor to hypertension , and there is recent work in this field as well. In this research , the relationships between hypertension and body weight with age were studied in Iraqi population . It is concluded that diastolic hypertension is separated from systolic and combined hypertension and increased body weight has little effect on increased blood pressure

Who is what and what is who: the morpho-syntax of Arabic WH

PhDThis thesis advances a micro-parametric analysis for the variation in wh-dependencies in a number of modern Arabic dialects, especially, Iraqi, Lebanese and Jordanian. It will be shown that although these dialects have much in common, there are certain differences in the strategies used in the formation of wh-questions. At a narrower level, it will also be shown that argument wh-phrases such as ‘who’ and ‘what’ in these dialects display asymmetric behaviour in the various wh-questions. In this thesis, I argue that cross-linguistic variation can only be accounted for in terms of morpho-syntactic properties of individual wh-phrases. As far as the Arabic dialects investigated here are concerned, I propose that wh-expressions such as Iraqi meno ‘who’ and Lebanese ˇsu ‘what’, unlike what has been assumed, are copular wh-phrases and, as such, have internally complex structures. It is this internal complexity, I argue, that directly affects their external syntax. To put the findings in perspective, this thesis examines the possibilities that Universal Grammar offers languages in terms of building wh-dependencies ranging from topicalisation and variable binding to relativisation and equation. The thesis, departs away, however, from mainstream approaches to cross-linguistics variation couched in the P&P framework (Chomsky 1981, 1986, 1995), such as LF-movement and binding, on the grounds that they are too rigid to capture the variation observed here. Instead, the thesis supports, and makes a contribution to, novel approaches to cross-linguistic variation, such as the Nanosyntax framework (Starke 2010, 2011), which take syntax to operate on (sub)-morphemic levels. Overall, the analysis has implications for the syntax of wh-constructions in general and the interaction at the morphology-syntax interface in particular
