Inductanceless high order low frequency filters for medical applications
In this paper, a designed circuit used for low-frequency filters is implemented and realized the filter is based on frequency-dependent negative resistance (FDNR) as an inductor simulator to substitute the traditional inductance, which is heavy and high cost due to the coil material manufacturing and size area. The simulator is based on an active operation amplifier or operation transconductance amplifier (OTA) that is easy to build in an integrated circuit with a minimum number of components. The third and higher-order Butterworth filter is simulated at low frequency for low pass filter to use in medical instruments and low-frequency applications. The designed circuit is compared with the traditional proportional integral controller enhanced (PIE) and T section ordinary filter. The results with magnitude and phase response were compared and an acceptable result is obtained. The filter can be used for general applications such as medical and other low-frequency filters needed
Fillers in Wood Adhesives
The introduction of a second component to polymers has been presented; this component is often used to modify the characteristics of the products and to acquire new polymer materials with improved properties. Composite materials have a pivotal role in industries that are now considered the most progressive worldwide. At present, synthetic adhesives based on formaldehyde such as phenol-formaldehyde (PF), urea formaldehyde (UF), and melamine formaldehyde (MF) are predominantly used for wood composite production, and these adhesives are commonly used in the wood panel industry. These adhesives have some advantages and disadvantages. The use of PF adhesives is as important as UF adhesives in the wood panel industry. However, their application is still limited because of its brittleness, brown color, high curing temperature, long curing time, and toxicity due to liberation of phenol and formaldehyde. A variety of methods have been used to improve the performance of UF and PF adhesives as well as to expand their use. These methods are widely used in the industry; they include the simple addition of fillers. Moreover, the addition of fillers could reduce shrinkage and alleviate the stress on the glue line, which improves the hardness and durability

Immigration policy and the role of political discourses in the relationship between foreign nationals and crime in England and wales
Significant criminological attention has been given to the relationship between immigration and crime. However, this relationship has not been researched in the UK to any great extent, and consequently the information on the UK context is limited. This research investigates how the criminality of foreign nationals have been constructed by examining the nature of immigration policy, foreign criminality discourses, and the media in the UK to understand how crime in particular has been used to define, refine, and inform control of immigrants.
This study refers to the legislative, policy, and political factors that underpin this process, and particularly explains how immigration policy and political debates have emphasised the criminality of foreign nationals in the UK. In order to achieve these goals, this research reviews a brief history of British immigration policy and legislation and outlines the connections made between foreign nationals and non-immigration criminal offences. In addition, secondary data from different British institutions and data collected via the Freedom of Information Act 2000 have been used to illustrate the level of foreigners’ criminality as well as the type of crimes compared to the British representation. Finally, Parliamentary debates and related political discourses have been used to examine the role of politics has in reinforcing the relationship between foreign nationals and crime and elevating negative public sentiment and the relationship with media reports.
This research highlights the limitations of existing data relating to the criminality of foreign nationals in offending records in England and Wales, partly due to the disorganised recording of offender nationality. This study reveals that nationality is the new racism; whilst immigration has become a central focus in political and public discourses on crime they as a group in statistical terms exhibit low levels of offending but are more likely to be imprisoned for less serious crimes.
The relationship between foreign nationals and crimes is thus a political issue rather than a legal one. As such, foreign nationals supposed criminality has been used to control immigration, avoid the blame of failing policies, gain electoral votes, and facilitate changes in immigration and crime policies.Ministry of Higher Education and Scientific Research in Ira
