No full textProf. Dr. Uda Hashim and his team won silver for MOS Transistor (Fabricated Using In-House Low Cost Facility) at ITEX 2006, 19th - 21st May 2006 at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur, Malaysia.MOS Transistor is divided into two types: NMOS and PMOS. Majority carrier od NMOS is electrons whereby PMOS is holes. The MOS transistor consists of three regions namely source, drain and gate. Fabrication of MOS transistor is done on 100mm silicon wafer. The active region of the transistor, which are source and drain are formed by either solid or liquid dopant. These transistors were fabricated using in-house low cost facility which is designed and developed by KUKUM internal expertise. The fabrication work is done in the cleanroom Class ISO 5 and ISO 6
Politics and ideology in a Protestant working class community in Belfast
No full textThe thesis considers the politics and ideology of Belfast's
Protestant working class (PKC). It is also conceived as a
contribution to discussions concerning the nature and theory of 'ideology' within the Marxist tradition. Traditional Irish Marxism has been dismissive of the PWC reducing their politics to the protection of marginal privelege sustained by Britain's Imperialist presence. This thesis argues that such a perspective is inadequate.
It is essential to move away from the concept of loyalist ideology as a systematised form of false consciousness, rather it is necessary to look at the ideology of Protestant workers at the level of day to day experiences and practices. Such collectively lived experiences give
the-alternative sets of practices embodied in working class culture. It is therefore important to draw on the sociological tradition of the community study. To fully understand PWC images of society it is necessary to construct the relationship between, local ideologies and
the theoretically developed ideologies, generated by national institutions. In order to do this the thesis looks at the social structure and politics of a particular PWC commmity in Belfast. The thesis then outlines by way of case study how the PWC have reacted to the contemporary political and social situation in Northern Ireland. The
thesis draws on interviews with residents, political activists and paramilitary members. In particular it identifies the politics and ideology of those active in the Democratic Unionist Party (DUP) and the Ulster Defence Association (UDA). In overall terms it highlights
the ideology by which Protestant workers make sense of, and give meaning to, their social and political worlds

N-succinyl-L,L-diaminopimelic acid desuccinylase (DapE) is a metallohydrolase involved in the meso-diaminopimelate (mDAP)/lysine biosynthetic pathway necessary for lysine biosynthesis and for building the peptidoglycan cell wall. Because DapE is essential for Gram-negative and some Gram-positive bacteria, DapE has been proposed as a good target for antibiotic development. Recently, L-captopril has been suggested as a lead compound for inhibition of DapE, although its selectivity for this enzyme target in bacteria remains unclear (Gillner et al. (2009)). Here, we tested the selectivity of L-captopril against DapE in bacteria. Since DapE knockout strains of gram-negative bacteria are viable upon chemical supplementation with mDAP, we reasoned that the antimicrobial activity of compounds targeting DapE should be abolished in mDAP-containing media. Although L-captopril had modest antimicrobial activity in Escherichia coli and in Salmonella enterica, to our surprise, inhibition of bacterial growth was independent both of mDAP supplementation and DapE over-expression. We conclude that DapE is not the main target of L-captopril inhibition in these bacteria. The methods implemented here will be useful for screening DapE-selective antimicrobial compounds directly in bacterial cultures
Efikasno određivanje sadržaja undecilenske kiseline u farmaceutskim preparatima: Novi, jednostavan pristup
No full textUndecylenic acid (UDA), a medium-chain fatty acid industrially derived from castor oil,
naturally occurs in black elderberry. UDA has attracted significant attention due to diverse
applications in pharmaceutical formulations, particularly as a topical antifungal agent. Recent
research has even hinted potential role of UDA in inducing apoptosis in tumor cells, further
elevating its importance in therapeutic contexts.
The primary objective of this study was to design a rapid and straightforward analytical
method for determining UDA content in commercially available preparations. The presence
of a terminal double bond in UDA enables it to undergo addition reactions, rendering it an
invaluable tool for quantifying UDA concentration in commercial products.The poster presentation of this conference paper was held during the 6th Student Section of the 31st International Conference on Ecological Truth and Environmental Research (EcoTER '24), which took place in Sokobanja, Serbia, from June 18th to 21st, 2024.

No full textUnsupervised Domain Adaptation for Disguised-gait-based Person Identification on Micro-Doppler Signatures
No full textIn recent years, gait-based person identification has gained significant interest for a variety of applications, including security systems and public security forensics. Meanwhile, this task is faced with the challenge of disguised gaits. When a human subject changes what he or she is wearing or carrying, it becomes challenging to reliably identify the subject's identity using gait data. In this paper, we propose an unsupervised domain adaptation (UDA) model, named Guided Subspace Alignment under the Class-Aware condition (G-SAC), to recognize human subjects based on their disguised gait data by fully exploiting the intrinsic information in gait biometrics. To accomplish this, we employ neighbourhood component analysis (NCA) to create an intrinsic feature subspace from which we can obtain similarities between normal and disguised gaits. With the aid of a proposed constraint for adaptive class-Aware alignment, the class-level discriminative feature representation can be learned guided by this subspace. Our experimental results on a measured micro-Doppler radar dataset demonstrate the effectiveness of our approach. The comparison results with several state-of-The-Art methods indicate that our work provides a promising domain adaptation solution for the concerned problem, even in cases where the disguised pattern differs significantly from the normal gaits. Additionally, we extend our approach to more complex multi-Target domain adaptation (MTDA) challenge and video-based gait recognition tasks, the superior results demonstrate that the proposed model has a great deal of potential for tackling increasingly difficult problems.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Microwave Sensing, Signals & System
The Agglutinin of Common Nettle (Urtica dioica L.) Plant Effects on Gene Expression Related to Apoptosis of Human Acute Myeloid Leukemia Cell Line
No full textTreatment of acute myeloid leukemia (AML) requires new drugs as result of a rise in new cases and high disease relapse. Plant lectins with the ability to bind carbohydrates on the cell surface have the potential to treat cancer. Urticadioica L. agglutinin (UDA) is a low weight lectin with anti-benign prostatic hyperplasia (BPH) impact. Here, we examine the impact of UDA on HL-60 cell line. Cytotoxicity and cytostatic effects were assessed in HL-60 cells treated with UDA and vincristine (positive control). The effects of the lectin on cell cycle phases and cell death mechanism were surveyed by propidium iodide (PI) staining and annexin V/PI, respectively. The activation status of the apoptosis pathway was determined by western blotting. Finally, the expression levels of 84 genes were examined by the Human cancer drug target gene PCR array kit. The results indicated that the increase in UDA concentration inhibited the proliferation of HL-60 cells as well as apoptosis induction. Cell cycle analysis showed that the number of sub G1 cells increased essentially. Experimental observations showed that UDA can induce cell apoptosis through a caspase 9-dependent pathway. The expression changes of 21 genes confirmed the apoptotic events in HL-60 cells treated with UDA. In this, we have presented the first investigation on the cytotoxic and apoptotic effects of a lectin isolated from rhizomes and roots of Urticadioica L. on human AML cells. Generally, the results suggest that UDA may have therapeutic value for leukemia and would be studied further as a new drug for AML later on. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature
