In Textile industry, production is mostly key concern for Industry owner. This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to add of charges of compressed air, manufacturing cost of air-jet weaving machine is higher as compared with rapier and projectile weaving machines. This is why countries having energy issues do not prefer air-jet weaving machines comparing projectile weaving machines. In this regard, several researchers and machine manufacturers have continuously been working to improve the efficiency of air-jet weft insertion. However, industry practice is as important as design made by researchers. The aim of this research is to investigate the air consumption of air-jet weaving on industrial scale practice. In this study, five weaving machine of same manufacturer and model were selected. It was observed that despite of manufacturing same quality of fabric, air consumption was varying almost in all weaving machines. Conventionally, mill workers adopt hit and trial practice in weaving industry including airpressure setting which leads to variation of nozzle pressure. Main reason of disparity of air consumption in air-jet weaving machines may be variation of distance from compressor to weaving machines, number of joints, un-necessary valve opening and pipes leakages cause an increase of compressed air consumption.

Philosophical Writings

In his philosophical writings, Coleridge increasingly developed his thinking about imagination, a symbolizing precursor to contemplation, to a theory of contemplation itself, which for him occurs in its purest form as a manifestation of ‘Reason’. Coleridge is a particularly challenging figure because he was a thinker in process, and something of an omnimath, a Renaissance man of the Romantic era. The dynamic quality of his thinking, the ‘dark fluxion’ pursued but ultimately ‘unfixable by thought’, and his extensive range of interests make essential an approach that is philosophical yet also multi-disciplinary. This is the first collection of essays to be written mainly by philosophers and intellectual historians on a wide range of Coleridge’s philosophical writings. With a foreword by Baroness Mary Warnock, and original essays on Coleridge and Contemplation by prominent philosophers such as Sir Roger Scruton, David E. Cooper, Michael McGhee, and Andy Hamilton, this volume provides a stimulating collection of insights and explorations into what Britain’s foremost philosopher-poet had to say about the contemplation that he considered to be the highest of the human mental powers. The essays by philosophers are supported by new developments in philosophically minded criticism from Coleridge scholars in English departments, including Jim Mays, Kathleen Wheeler, and James Engell. They approach Coleridge as an energetic yet contemplative thinker concerned with the intuition of ideas and the processes of cultivation in self and society. Other essays, from intellectual historians and theologians, clarify the historical background, and ‘religious musings’, of Coleridge’s thought regarding contemplation.

Studies over the past 30 years have revealed that adipose tissue is the major endocrine and paracrine organ of the human body. Arguably, adiopobiology has taken its reasonable place in studying obesity and related cardiometabolic diseases (CMDs), including Alzheimer’s disease (AD), which is viewed herein as a neurometabolic disorder. The pathogenesis and therapy of these diseases are multiplex at basic, clinical and translational levels. Our present goal is to describe new developments in cardiometabolic and neurometabolic adipobiology. Accordingly, we focus on adipose- and/or skeletal muscle-derived signaling proteins (adipsin, adiponectin, nerve growth factor, brain-derived neuroptrophic factor, neurotrophin-3, irisin, sirtuins, Klotho, neprilysin, follistatin-like protein-1, meteorin-like (metrnl), as well as growth differentiation factor 11) as examples of metabotrophic factors (MTFs) implicated in the pathogenesis and therapy of obesity and related CMDs. We argue that these pathologies are MTF-deficient diseases. In 1993 the “vascular hypothesis of AD” was published and in the present review we propose the “vasculometabolic hypothesis of AD.” We discuss how MTFs could bridge CMDs and neurodegenerative diseases, such as AD. Greater insights on how to manage the MTF network would provide benefits to the quality of human life.

The Relationship

Teacher education programme is a critical component of education and the life of any society. It normally lays the very foundations of the society. It spurs and pushes the various aspects of development in the society through well-established culture and character of such a society. But for this programme of education to perform this development function efficiently it must be well designed, developed and constantly reformed and modernized so as to keep it abreast with the emerging issues both in education and society. This process is only possible through the conduct of regular studies in education and society to establish new developments and also facilitate the generation of relevant innovations to promote the quality of Teacher education programme. However, there is no evidence that such a process has ever been initiated and conducted in Teacher education programme since the inception of this programme in modern Africa. This paper is designed to explore the importance of Teacher education programme in modern Africa, the relationship between Teacher education programme and development in modern Africa, the roe of this programme in modern Africa, strategies of harnessing the programme for development in modern Africa and the challenges of the programme in modern Africa. This narrative is likely to shade light on the need of Teacher education programme in development in modern Africa and the role of innovative research in this process. Hence, set in motion the desired development in modern Africa.

The ovine population of the central Argentine territory is the result of constant introductions of different animal biotypes, which determined the existence of ovine populations with great variability. The main objective of the breeders is to produce a lamb for self-consumption and sale of surpluses, without considering the wool product. The production of a lamb for the market is compatible with the production of wool for the textile industry, having to evaluate the feasibility for the commercialization of lamb wool that they produce. This work aimed to provide information and tools to evaluate the quality of lamb’s wool and the evolution of the weight of lambs belonging to the native flocks of the area. Characterization of the productive systems was carried out, seeking to highlight the attributes of meat and wool of native lambs. The characteristics of wool and meat lamb product were evaluated under two treatments, either in free rage conditions or lambs supplemented under confinement. The analysis of the behaviour of the productive systems did not show significant differences between lamb biotypes, which allows affirming that the variation within an animal biotype is even more important than the expected one between biotypes. This indicates that both treatments can be used according to the particular situation of each productive unit. Therefore, it is possible to produce wool and meat of outstanding quality looking for the goodness of the wool produced and optimizing through proper handling practices the meat product.

With emergent subspecialties like data journalism bringing new skillsets and job roles, professionals and journalism educators find it difficult to imbibe the fast-changing industry demands. Such challenges in some countries and media industries put journalism educators in an advantageous position, offering them an agency to actively shape the contours of industry practice than getting shaped by it. From this perspective, the present study tries to understand data journalism practices in India and suggests certain insights to integrate data journalism training in programmes offered by Indian journalism education. By probing insights from the literature on data journalism education and by examining existing data journalism practices in India, the study calls for intervention with a pedagogic strategy to impart better data-sourcing practices, coding skills and critical data literacy among the students as an antidote to the prevalent DIY culture and overdependence on data aggregates. The pedagogic strategy should convey the importance of audience centrality and ethics in data journalism practice. It argues that such an approach can, in effect, improve industry practices as well as the quality of journalism education in India.

PurposeThe quality of produced textile fibers plays a very important role in the textile industry, and detection and assessment schemes are the key problems. Therefore, the purpose of this paper is to propose a relatively simple and effective technique to detect and assess the quality of produced textile fibers.Design/methodology/approachIn order to achieve automatic visual inspection of fabric defects, first, images of the textile fabric are pre-processed by using Block-Matching and 3-D (BM3D) filtering. And then, features of textile fibers image are respectively extracted, including color, texture and frequency spectrum features. The color features are extracted by using hue–saturation–intensity model, which is more consistent with the human vision perception model; texture features are extracted by using scale-invariant feature transform scheme, which is a quite good method to detect and describe the local image features, and the obtained features are robust to local geometric distortion; frequency spectrum features of textiles are less sensitive to noise and intensity variations than spatial features. Finally, for evaluating the quality of the fabric in real time, two quantitatively metric parameters, peak signal-to-noise ratio and structural similarity, are used to objectively assess the quality of textile fabric image.FindingsCompared to the quality between production and pre-processing of textile fiber images, the BM3D filtering method is a very efficient technology to improve the quality of textile fiber images. Compared to the different features of textile fibers, like color, texture and frequency spectrum, the proposed detection and assessment method based on textile fabric image feature can easily detect and assess the quality of textiles. Moreover, the objective metrics can further improve the intelligence and performance of detection and assessment schemes, and it is very simple to detect and assess the quality of textiles in the textile industry.Originality/valueAn intelligent detection and assessment method based on textile fabric image feature is proposed, which can efficiently detect and assess the quality of textiles, thereby improving the efficiency of textile production lines.

Pruning Techniques

Pre-harvest application of prohydrojasmon (PDJ) or abscisic acid (ABA) induces the red color in fruits that were exposed to sunlight at the orchard. In this large-scale work, we evaluated the effect of two different pruning techniques of ‘Kent’ mango orchards, one leading to opening the orchard canopy to expose as much fruit as possible to sunlight, while the second pruning leads to square-shaped trees and subsequently reduces the amount of sunlight reaching the fruit. These two pruning methods were combined with preharvest spraying with prohydrojasmon (PDJ) or abscisic acid (ABA) using two different types of sprayers, i.e., regular and air-jet sprayer. Pruning the canopy of the orchards to open and closed trees exposed 80% or 30% of fruits to sunlight, respectively. Both of the application with air-jet and regular sprayers effectively covered the fruit without causing fruit detachment and damage to yield. Both the phytohormones (PDJ and ABA) application treatments induced red blush skin, red intensity, anthocyanin, and flavonoids, particularly in fruit grown outside the tree canopy in both open and closed trees. PDJ and ABA treatments exhibited marginally reduced acidity than the untreated control, while the brix was not affected much by any of the treatments. Besides these, exposure to sunlight and PDJ treatment also reduced postharvest decay and increased chlorophyll degradation and yellowing in comparison to the controls. This study promoted applicative evidence about the positive effects of exposure to sunlight, prohydrojasmon (PDJ), and abscisic acid (ABA) on red color development without compromising the mango fruit’s quality.
