The Biochemist — August 2003. © 2003 The Biochemical Society 28 this is 216=65 536 levels of grey. The higher the number of grey levels, the greater the dynamic range of the camera. In simple terms, a good dynamic range allows real-time image capture, but shows such low noise levels that it can acquire images over long periods. Therefore, it is ideal for quantifying chemiluminescent band images...

The main objective for the present research is to assess effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body compositions (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyceride...

Introduction: In the present research, the effect of morphine consumption during pregnancy on the development of the embryo’s spinal cord was studied in Wistar rat. Methods: Female Wistar rats (Wt: 250-300 g) were mated with males. The test group received morphine (0.01 mg/ml) in their drinking water. Pregnant rats were later killed with chloroform on the 12th, 13th and 14th days of pregnancy, ...

Tumor segmentation of MRI Brain images is still a challenging problem. This paper proposes a fast MRI Brain image segmentation method based on Artificial Bee Colony (ABC) algorithm. The value in a continuous gray scale interval is searched using threshold estimation. The optimal threshold value is searched with the help of ABC algorithm . In order to get an efficient fitness function for ABC al...

Decentralized water reuse in cities is a prominent alternative to mainstream top-down models for urban treatment, which are based on centralized, linear dynamics of resource management. In this sense, Nature-based Solutions (“green” technologies) coupled with advanced technologies (“grey” constitute promising approach fomenting onsite treatment and cities, while also providing multiple co-benef...

Nowadays, in competitive environment, a fundamental factor that helps governmental and non-governmental organizations to achieve their goals is attention to efficiency and its continuous improvement, which is only possible through continuous Efficiency Evaluation. Data Envelopment Analysis (DEA) is a suitable method for Efficiency Evaluation in organizations. But one limitation of this method i...

Concrete with gangue which made with ordinary Portland cement at different water binder ratio (0.35, 0.40 and 0.45) or ordinary Portland cement at water binder ratio of 0.35 incorporating 10% fly ash or 20% fly ash; 20% fly ash and 1% early strength agent, slag with the replacement of 15% or 30%, or 15% fly ash and 15% slag were made and exposed to a wetting–drying sulfate environment. The comp...

The openness of Android OS and the easy development of applications have attracted a large number of enthusiasts to join in. Due to the deficiencies of permission mechanism of Android OS, an Android privacy protection system called Protectedroid is presented in this paper which is a model based on grey list and enables the design of security strategies more easily. Protectedroid adds an enforci...
