National Textile University, or NTU, is the premier institution of Textile Education in Pakistan. It was formerly known as National College of Textile Engineering affiliated with University of Engineering and Technology, Lahore since 1976. The University campus is spread over an area of more than 62 Acres. The University is located in the outskirts of city of Faisalabad about 12 km from the city center on Sheikhupura road. National Textile University is affiliated with National Computing Education Accreditation Council , Pakistan Engineering Council and Higher Education Commission of Pakistan . Pakistan had inherited a very weak industrial base in the aftermath of independence. Textile sector was one of the sectors of Pakistani economy, which were in a comparatively better shape than others. Even then it was not enough to produce the number of jobs that could reduce the rampant unemployment rate in the absence of basic infrastructure facilities and a sound industrial base in the country.Throughout all these years, Pakistan's textile Industry has evolved and developed into a formidable force in steering the nation's economy forward, due to the entrepreneurial spirit of Pakistani industrialists and an established agricultural base in the shape of indigenous Cotton production. Textile sector now accounts for about $12 Billion worth of exports annually, out of Pakistan's total $25 Billion exports. Textile has become a sector which keeps on fetching more and more foreign capital to reinforce fragile Pakistani economy.The role of National Textile University in propelling Pakistan's Textile Industry in the forward direction is mammoth. It holds the privilege of being a pioneering institution in the field of Textiles, over all these years, this institution has catered for the industry's ever increasing demand of Textile engineers and skilled diploma holders. According to some estimates, 90% of Textile engineers in Pakistan's Textile Industry, identify National Textile University as their alma mater.Over all these years, Pakistan has seen a major surge in the number of Textile institutions, which offer diverse degree programs in the field of Textiles. A matter of prodigious delight and honor for National Textile University's students and alumni alike is that, even with such a fierce competition, industrial establishment still prefers Textile engineers holding a degree from National Textile University. This reaffirms their trust in the technical and academic prowess of engineering professional from this distinguished institution. Wikipedia.

Surface energy (SE) is the most sensitive and fundamental parameter for governing the interfacial interactions in nanoscale carbon materials. However, on account of the complexities involved of hybridization states and surface bonds, achieved SE values are often less in comparison with their theoretical counterparts and strongly influenced by stability aspects. Here, an advanced facing-target pulsed dc unbalanced magnetron-sputtering process is presented for the synthesis of undoped and H/N-doped nanocrystalline carbon thin films. The time-dependent surface properties of the undoped and H/N-doped nanocrystalline carbon thin films are systematically studied. The advanced plasma process induced the dominant deposition of high-energy neutral carbon species, consequently controlling the intercolumnar spacing of nanodomain morphology and surface anisotropy of electron density. As a result, significantly higher SE values (maximum = 79.24 mJ/m2) are achieved, with a possible window of 79.24-66.5 mJ/m2 by controlling the experimental conditions. The intrinsic (size effects and functionality) and extrinsic factors (atmospheric exposure) are resolved and explained on the basis of size-dependent cohesive energy model and long-range van der Waals interactions between hydrocarbon molecules and the carbon surface. The findings anticipate the enhanced functionality of nanocrystalline carbon thin films in terms of selectivity, sensitivity, and stability. © 2017 American Chemical Society.

Mass segmentation in mammograms is a challenging task due to problems such as low contrast, ill-defined, fuzzy or spiculated borders, and the presence of intensity inhomogeneities. These facts complicate the development of computer-aided diagnosis (CAD) systems to assist radiologists. In this paper, a novel mass segmentation algorithm for mammograms based on robust multiscale feature-fusion, and automatic estimation based maximum a posteriori (MAP) method is presented. The proposed segmentation technique consists of mainly four stages: a dynamic contrast improvement scheme applied to a selected region-of-interest (ROI), background-influence correction by template matching, detection of mass candidate points by prior and posterior probabilities based on robust multiscale feature-fusion, and final delineation of the mass region by a MAP scheme. This segmentation method is applied to 480 ROI masses that used ground truth from two radiologists. To compare its effectiveness with the state-of-the-art segmentation methods, three statistical metrics are employed. The experimental results indicate that the developed methods can reliably segment ill-defined or spiculated lesions when compared to other algorithms. Its integration in a CAD system may result in an improved aid to radiologists. © 2012 Elsevier Ltd.

Background: Computer-aided pattern classification of melanoma and other pigmented skin lesions is one of the most important tasks for clinical diagnosis. To differentiate between benign and malignant lesions, the extraction of color, architectural order, symmetry of pattern and homogeneity (CASH) is a challenging task. Methods: In this article, a novel pattern classification system (PCS) based on the clinical CASH rule is presented to classify among six classes of patterns. The PCS system consists of the following five steps: transformation to the CIE L*a*b* color space, pre-processing to enhance the tumor region and removal of hairs, tumor-area segmentation, color and texture feature extraction, and finally, classification based on a multiclass support vector machine. Results: The PCS system is tested on a total of 180 dermoscopic images. To test the performance of the PCS diagnostic classifier, the area under the receiver operating characteristics curve (AUC) is utilized. The proposed classifier achieved a sensitivity of 91.64%, specificity of 94.14%, and AUC of 0.948. Conclusion: The experimental results demonstrate that the proposed pattern classifier is highly accurate and classify between benign and malignant lesions into some extend. The PCS method is fully automatic and can accurately detect different patterns from dermoscopy images using color and texture properties. Additional pattern features can be included to investigate the impact of pattern classification based on the CASH rule. © 2011 John Wiley & Sons A/S.

Heavily exudating wounds can lead to infection and unnecessary trauma if they are not adequately managed. Manufacturers involved in production and marketing of high absorption silver dressings, besides emphasising high absorptions of their dressings are keen to highlight potent antimicrobial abilities of their products against all kinds of pathogens including MRSA. However, there are little or no credible reports on minimal but potent quantities of silver needed in a dressing to eliminate bacteria spread and growth or how effectively the silver within a dressing is released over time. This paper introduces a new hybrid biomaterial fibre made from polysaccharide-based polymers with inbuilt ability to gel and absorb large quantities of pseudo exudates. Furthermore, it will be reported that the new fibre carries up to six times less silver than it is conventionally used in silver dressings and displays a very slow rate of release whilst maintaining full potency over time against known Gram positive, Gram negative micro-organisms including MRSA. The paper concludes that the developed hybrid fibre has long lasting antimicrobial and gelling properties comparable, if not better, than Acticoat AA and Aquacel Ag, two commercially available silver dressings. © 2013 Elsevier Ltd.

The present paper envisages the multi-response optimization of certain process parameters like total sugars concentration, C/N ratio and incubation time on rhamnolipid yield, surface tension reduction, biomass formation and substrate utilization, in rhamnolipid production by a Pseudomonas aeruginosa mutant strain grown on clarified blackstrap molasses, under L9 orthogonal array in Taguchi design. The results have been analyzed by using grey relational analysis for the identification of an optimum level of process parameters. The validity of the results was checked though confirmation experiment, under grey relational analysis. Subsequently, the rhamnolipid yield improved from 1.45 to 1.50 g/L, substrate utilization reduced from 26 to 14% (w/v) and lesser biomass was formed. Moreover, the volumetric productivity of the process improved from 0.0086 to 0.0208 g/L/h by 142%. Furthermore, using analysis of variance method, significant contributions of process parameters were determined. © 2014 The Authors.

The synthesis of Trimethylol Melamine (TMM) precondensate was carried out by the controlled reaction of formaldehyde with melamine, which belonging to class of partially methylolated thermosetting resins. The product was clear, transparent, viscous and miscible with water. The refractive index, density and maximum absorption of the synthesized TMM was determined. The dyed (C.I. Direct Red 2) cotton and rayon specimens were impregnated with synthesized precondensate (TMM) and Fix M-3(commercially available trimethylol melamine of BSF product), cured at 150°C for 3 min using curing catalyst. The performance of the synthesized and Fix M-3 evaluated using rubbing, washing and light fastness tests. The rubbing fastness to crocking, color fastness to washing and light fastness is reported and found to be dependent on the fixing efficiency of fixer. The fastness to light is found to be dependent on the aromatic character of melamine ring which obviously due to the preferably absorption in the UV region.

A series of mono and di-chlorotriazinyl based reactive red dyes were synthesized containing the common H-acid nucleus with different reactive coupling groups-sulfanilic acid, metanilic acid, orthanilic acid, anthranilic acid and tobias acid. These syntheses were monitored by thin-layer chromatography (TLC). The solubility of the synthesized dyes was investigated in water at various temperatures. Their Spectrophotometric data indicated significant alteration in their ëmax values which corresponded to the nature of the substituents (-SO3H, -COOH) of the diazocomponents used. The bi-functional bridged reactive dyes, containing the derivatives of anthranilic acid (KPR-15, KPR-16) showed the highest secondary exhaustion degree from the dyebath while derivatives of tobias acid showed the highest fixation ratio (KPR-19, KPR-20). The improved fastness properties of perspiration, washing and light were investigated. The fabrics with an intense color and good characteristics were obtained, thus presenting a possibility for the extension of usually applied reactive red dyes.

Microwave heating was incorporated into the resin transfer moulding technique. Polytetrafluoroethylene (PTFE) mould was used to cure the composite panel. Through the use of microwave heating, the mechanical and physical properties of produced Kevlar fibre/polyester composites were compared to those manufactured by conventional resin transfer moulding. The flexural modulus and flexural strength of 6-ply conventionally cured composites was 45% and 9% higher than the flexural modulus and flexural strength of 6-ply microwaved cured composites, respectively. However, 19% increase in interlaminar shear strength (ILSS) and 2% increase in compressive strength was observed in 6-ply microwave cured composites. This enhancement in ILSS and compressive strength is attributed to the better interfacial bonding of polyester resin with Kevlar fibres in microwaved cured composite, which was also confirmed via electron microscopy scanning. Furthermore, the microwave cured composite yielded maximum void contents (3%).

The deposition of material at the edge of an evaporating droplet is known as the coffee ring effect. This phenomenon is widespread in various colloidal and bacterial systems. The study has examined the self-assembly and deposition of colloidal rhamno-lipid (a natural surfactant) structures on a glass surface. The effects of the rhamnolipid concentration, pH and the addition of cations on the deposition formation and the alteration in coffee ring effect were studied by using in-vitro scanning electron microscope observation. Above the critical micelle concentration, a transition from ring-like deposition to dispersed deposition is observed. Whereas upon the addition of cations, the multi-distribution of aggregates size enhances the non-homogeneity of the drying film and consequently results in multi-nucleation of rhamnolipid aggregates. © Carl Hanser Publisher, Munich. © Carl Hanser Verlag GmbH & Co.
