Preparation of Fish Scales Hydroxyapatite (FsHAp) for Potential Use as Fillers in Polymer

The aims of this study were to prepare natural hydroxyapatite from fish scales(FsHAp)for potential use as a filler in polymer.The FsHAp was prepared from Tilapia fish scales using thermal method.The FsHAp was milled for 48 h and dried by spray method.The morphology was characterized using field emission scanning electron microscope(FESEM)which showed irregular shape of FsHAp particles with particle size around 7μm.The analysis of FsHAp was carried out using Fourier transform infrared spectroscopy(FTIR)and X-ray diffraction(XRD)to confirm chemical structure of FsHAp.

The Relationship between Corporate Social Responsibility and Financial Performance of Iraqi Corporations: A Literature Review

This paper aims to explore past researches that examine the relationship between corporate social responsibility (CSR) and financial performance. The researcher intends to conduct researches that examine the relationship between CSR and financial performance in Iraq corporations. This paper highlights review of literatures from various countries that examine relationships between CSR with financial performance. This paper is based on secondary sources which are accumulated from many researches in Malaysia, Australia, UK, Indonesia, Sri Lanka, Nigerian, and Jordan. The study uses information generated from literature reviewed from different researchers relating to the topic. This method was applied by collecting information from journals and online sources relating to the issue under consideration. Regression analysis documents significant evidence to support a positive relationship between CSR and financial performance. Evidence suggests that CSR leads to good financial performance in Iraq corporations. Findings based on the review revealed that researchers also showed that there was a significant positive relationship between CSR practice and financial performance in Iraq corporations. This study focuses on disclosures made in the corporate annual reports. This is because the annual report is the common document produced by companies on a regular basis and is widely used in prior studies related to CSR. The study provides some important insights for our understanding of CSR in developing economies and its effects on financial performance in the context of Iraq companies.

Colour Features Extraction Techniques and Approaches for Content-Based Image Retrieval (CBIR) System

An image retrieval system was developed purposely to provide an efficient tool for a set of images from a collection of images in the large database that matches the user’s requirements in similarity evaluations such as image content similarity, edge, and colour similarity. Retrieving images based on the contents which are colour, texture, and shape is called content-based image retrieval (CBIR). This paper discusses and describes about the colour features technique for image retrieval systems. Several colour features technique and algorithms produced by the previous researcher are used to calculate the similarity between extracted features. This paper also describes about the specific technique about the colour basis features and combined features (hybrid techniques) between colour and shape features.
