Problems of land readjustment process in Turkey
Land readjustment is a method providing alternative potentials for both its implementing authorities and the property owners. Thus, the consistency of the legal framework which determines the way of the method used is of great importance. However, how the method is applied in Turkey is considered problematic. The main problems in the method are; exclusion of property owners from the participative process, calculating...

The effect of crude oil on microorganisms and dry matter of fluted pumpkin (Telfairia occidentalis)
The effect of crude oil on microorganisms and dry matter of fluted pumpkin (Telfairia occidentalis) was investigated. The soil was treated with different levels of crude oil: 0% (control), 1, 3 and 6% v/w. There was no significant different in bacteria count after 35 days in all the treatments. The mean fungi count of 4.5±0.4 x104 and 3.3±0.5x104cfu/g in the 3% and 6% pollutions, respectively. Pumpkin...

Improving the performance of bubble sort using a modified diminishing increment sorting
Sorting involves rearranging information into either ascending or descending order. There are many sorting algorithms, among which is Bubble Sort. Bubble Sort is not known to be a very good sorting algorithm because it is beset with redundant comparisons. However, efforts have been made to improve the performance of the algorithm. With Bidirectional Bubble Sort, the average number of comparisons is slightly reduced and...

A comparison of problem-based learning and traditional lecture students’ expectations and course grades in an introductory physics classroom
The purpose of this study was to compare problem-based learning (PBL) and traditional lecture students’ expectations about physics and physics learning and course grades in an introductory physics classroom. A total of 264 (PBL, n = 100; traditional, n = 164) freshman engineering students of Dokuz Eylul University (DEU) in Izmir, Turkey participated in the study. Student expectations were measured through the pre...

The role of satellite remote sensing data and GIS in population census and management in Nigeria: A case study of an ea in Enugu, Nigeria
The paper examines the nature of census operations in Nigeria and identifies the contribution of satellite remote sensing (SRS) data and geographic information system (GIS) to the contingency planning, mapping and management of census (attributes) datasets in Nigeria. Enumeration Areas (EAs) of a site in Enugu, Nigeria was mapped. The census datasets were modeled and presented as an ideal process. This was...

Environmental mitigation and regeneration through sustainable farming and food security
We recognized the farming practice of the communities around Keyo hills in Kilak, which is a complex and fragile ecosystem, as being purely dependent on annual food and cash crops production system and rain fed agriculture in nature. There are noticeable decline in food and cash crops production in the area. There are regular reported cases of mild to severe famine in the northern and eastern parts of Uganda. The...

Effect of the computer based game on pre-service teachers’ achievement, attitudes, metacognition and motivation in chemistry
The purpose of this study is to explore whether the support of traditional teaching methods with computer based games has any effect on students’ achievement in chemistry course, their attitude towards chemistry, their metacognition level and motivation. For this aim, before the application, Chemistry Achievement Test (CAT), Chemistry Attitude Scale (CAS) and Metacognitive Activities Inventory...

The effect of mineral admixture type on the modulus of elasticity of high strength concrete
In this article, 2 sources was studied , rich in reserves, pumice and zeolite’s effects on elasticity modulus which is an important criterion of high strength concrete (HSC), for this reason, HSC was produced by pumice and zeolite’s replacement for the concrete in proportion of “0, 5, 10 and 15%” to the binder mass. Deformation controlled compressive strength tests was performed on concrete...

Mode of joint action response to binary mixtures of three refined petroleum products by Nile tilapia Oreochromis niloticus fingerlings
The toxicities of three refined petroleum products and their binary mixtures based on predetermined and equitoxic ratios of 1:1, 1:6 for petrol-kerosene; 1:1, 1:2 for petrol-diesel and 1:1, 1:3 for diesel–kerosene respectively were evaluated against the fingerlings of Oreochromis niloticus, in laboratory bioassays. The interactions between binary mixtures showed significant departures from the action of the...

Screening of organophosphorus pesticides in a Taiwanese agricultural community college
Two schools in Southern Taiwan, one college school in an agricultural area and another senior high school in a metropolitan area, were selected for assay of 46 organophosphorus pesticides in air during July 2007. Analytical results for samples collected outside the classroom in an agricultural area showed that chlorpyrifos had the highest detection frequency (50%) and its median and arithmetical means of measured...
