Hemoglobin A1c is the most parameters for the monitoring of metabolic control of patients with diabetes mellitus. The aim of this study is to determine the reference rang of glycosylated hemoglobin (Hb A1c%) in an Iraqi population (males  and females)  and predict  Bp systolic diastolic by using demonstrates the application of decision tree, as data mining tool, in the health care system. Data mining has the capability for classification, prediction, estimation, and pattern recognition by using health databases.

In this paper, labor market performance in Sub-Sahara Africa has been modeled using convex optimization. Labor market indicators have been adopted as a reliable source of information capable of describing Sub-Sahara Africa labor market condition.

The paper assesses the level of satisfaction derived by the users of academic buildings in Yaba College of technology. The research which is largely field based had questionnaires randomly administered on a total of 290 respondents in a total of nine buildings that were equally randomly selected. Data solicited include respondent’s data and level of satisfaction derived by them from using the building in question using the five scale likert scale method.

Cities are becoming increasingly vulnerable to water related issues due to rapid urbanization, installation of complex infrastructure, and changes in the rainfall patterns. This study aims at assessing the impacts of climate change on rainwater harvesting systems (RWH) at the tropical urban city Taipei, Taiwan.

A new Viscosity bath has been entered the services in Thermal Metrology Laboratory-National Institute for Standards, NIS-Egypt in order to use in maintain and extend the national viscosity scale in wide temperature ranges, international comparison and routine calibration of viscometers. The medium of the bath should be homogenous enough in temperature so many thermal factors taken into account to estimate the temperature gradient, homogeneity, stability and thermal profile distribution with the  related uncertainty to each parameter.

The specially designed pykanometre and dilatometer is used to measure the temperature variation of density of two liquid crystalline CBOnO.m compounds namely

1. α-(4-cyanobiphenyl-4 heptyloxy)-ω-4-n-alkylanilinebenzylidene-4oxy)decane (C1)
2. α-(4-cyanobiphenyl-4 decyloxy)-ω-4-n-alkylanilinebenzylidene-4oxy)decane (C2)

This study, Nano Zero Valente Iron (NZVI) was produced with different stabilizers (Sodiumcarboxymethylcellulose, CMC, Polyvinylpyrrolidone, PVP, Hexadecyltrimethylammonium bromide, CTAB using kinetic energy micro reactor (K-M reactor). There action between Ferric chloride (FeCl3.6H2O) with different stabilizers and Sodium borohydriede (NaBH4) as reducing agent at K-M reactor gives many advantages in comparison with traditional chemical method for production of dispersed Nano ironin batch reactor.

Micro course is a kind of new learning resources in recent years, and it has the characteristics of focus, practical and fast food. These characteristics meet the current fast pace of life, people just want to in the limited time learn useful knowledge for their needs. This study interprets the meaning of the class, analyzes the micro course resources platform features and functional requirements. And on this basis, the thesis focus on open platform design for micro course resource for three aspects: overall planning, function structure and application process.

A pentablock copolymer was prepared via the atom transfer radical polymerization of 2-hydroxyethyl methacrylate (HEMA) initi-ated by 2-bromoisobutyryl end-capped PPO-PEO-PPO as a macroinitiator in DMF. Attaching PHEMA blocks altered the self-assembly process of the pentablock copolymer with γ-CDs in aqueous solution. Before attaching the PHEMA, the macroinitiator was preferentially bent to pass through the inner cavity of γ-CDs to give rise to tight-fit double-chain stranded polypseudorotax-anes (PPRs).

The complexes of Cr(III), Co(II), Ni(II), Hg(II), Cd(II) were microwave synthesized with the ligands Nicotinicacidhydrazide and (ONO)2 and characterized by using Elemental analysis, Molar conductance measurements, IR, NMR, spectroscopic studies. DNA-binding properties have been studied by electronic absorption, emission, viscosity and cyclic voltametric methods. The results suggest that the copper (II) complex bind to DNA via different modes.
