On Digital Metric Space Satisfying Certain Rational Inequalities

In this paper, we have established some new results by extending some existing theorems in the setting of Digital Metric Space. We also proved some results in Digital Metric Space which were established earlier in the context of Complete Metric Space by different authors

Social Consciousness in the Short Stories of Mahasweta Devi

Mahasweta Devi, a well-known name in the scenario of Indian English literature, a political and social activist worked with and for tribal and marginalized communities of eastern India throughout her life. The social conscious or aware of the problems within the society or community compels Devi to writes and protests actively against social injustice.  She wants to see the change in the society, therefore takes an active role to eradicate poverty, injustice, exploitation of the subaltern. Her commitment towards the society as reflected the story ‘Little Ones', ‘Fisherman', ‘Hunt', has been highlighted in the paper

On the ADI method for the Sylvester Equation and the optimal-H2\mathcal{H}_2 points

The ADI iteration is closely related to the rational Krylov projection methods for constructing low rank approximations to the solution of Sylvester equation. In this paper we show that the ADI and rational Krylov approximations are in fact equivalent when a special choice of shifts are employed in both methods. We will call these shifts pseudo H2-optimal shifts. These shifts are also optimal in the sense that for the Lyapunov equation, they yield a residual which is orthogonal to the rational Krylov projection subspace. Via several examples, we show that the pseudo H2-optimal shifts consistently yield nearly optimal low rank approximations to the solutions of the Lyapunov equations

Surface modification of polyester using chicken feather keratin hydrolysate to improve water absorbency and dye uptake

PET fiber has an intrinsic low hydrophilic character and an inactive surface which make it uncomfortable for wearing purpose. Moreover, it is difficult to colour polyester fabric other than disperse dyes. Therefore, surface modification of PET is very important to improve its absorbency and bring the possibility to dye polyester with anionic dyes by altering its surface characteristics. This research was focused on surface modification of polyester using chicken feather which involves serine as the most abundant amino acid with hydroxyl groups. The treated polyester fabric using 20ml/L concentration of chicken feather extract showed improved water drop absorbency from 45 into 3 seconds and the reactive dye uptake by 36 folds from 0.15 to 5.37 K/S values

Some Common Fixed Point Theorems for Rational Type Contractive Mappings in Complex Valued Metric Spaces

We prove some common fixed point theorems for two pairs of weakly compatible mappings satisfying a rational type contractive condition using (E.A.) and (CLR)-property in Complex Valued metric spaces. The proved results generalize and extend some of the results in the literature. Keywords: Complex Valued metric space, weakly compatible mappings, (E.A.) - property, (CLR)-property. Mathematics subject classification: 47H10, 54H25

Prise en charge de la maladie de Crohn fistulisante dans une population marocaine: à propos de 78 cas

La maladie de Crohn est une entérocolite inflammatoire, qui peut se compliquer de fistules entéro-entérales, entéro-vésicales, rectovaginales, entéro-cutanées et anopérinéales. Il s'agit d'une étude rétrospective portant sur les cas de maladie de Crohn fistulisante suivis dans le service de gastroentérologie au CHU Mohamed VI de Marrakech, sur une période allant de 2008 à 2014. 78 patients présentaient une forme fistulisante de la maladie de Crohn. La localisation des fistules était représentée par les fistules entéro-entérales (29,6%), suivie des fistules anopérinéales (26,9%) et entéro-cutanées (23%), puis des fistules entéro-vésicales (9%) et recto-vaginales (3,8%). Le traitement chirurgical a été indiqué d'emblée dans tous les cas de fistules entéro-entérales, entéro-cutanées, entéro-vésicales, 57,1% des cas des fistules anopérinéales et 66,7% des cas des fistules recto-vaginales. Six cas de fistules anopérinéales ont été mis sous immunosuppresseurs. Seuls 3 cas de fistules anopérinéales et un cas de fistules recto-vaginales ont été mis sous infliximab. La récidive endoscopique était significativement plus fréquente chez les patients opérés, traités en post-opératoire par les aminosalicylés par rapport à ceux traités par des immunosuppresseurs (P=0,0008). La rémission clinique était également significativement associée au traitement médical par les immunosuppresseurs par rapport aux aminosalicylés (P=0,0018). Le traitement chirurgical reste indiqué dans la majorité des cas de la maladie de Crohn fistulisante

Gaining a Better Understanding of Higher Education: During and Post-Pandemic Scenario

Because of the coronavirus epidemic, faculty as well as the students have had to respond to “out of the ordinary” difficulty by quickly switching from traditional class - room education to online learning forms via “virtual classrooms”. Students facing challenges and continuing facing difficulties for various reasons required to adapt this modification in this delivery of curriculum becoming un attentive. Few solutions have been developed for students to assist them in freely transferring to virtual classrooms and maintaining proper online learning etiquette. A series of recommendations is offered in the present study to help students so that they can explore and improve their involvement in the classroom held in online or “virtual classroom”. Taking this view into account the viewpoint is that higher education is in the epicenter of this epidemic that serves a varied fraternity of students. Triggering fruitful conversation among teachers dealing with and adapting technology to render their services during this epidemic could be helpful in “re-imagining” and “re-designing” subsequent courses. It is presumed that in the aftermath of the outbreak or in the new normal, this could aid subsequent considerations to generate the superior habits and rules and regulations required to continue this “virtual classrooms”

Green IT towards Digitalizing India

Digital India is an initiative by government of India which will prove as a blessing for Indian citizens and will also assist in connecting dots between past, present projects in India. Over the years biggest challenge for India has been to communicate information to this gigantic population. Digital Platform is one of the most efficient ways of communicating information to 1.2 billon citizens of India. Green Computing and Green technology are adopted by developed countries to reduce the impact of growing usage of computing equipments. Apache Hadoop is one of the best upcoming technologies to maintain and analyze Big Data. Hadoop can be implemented on with normal computing and also with cloud computing. Efficient use of Green technology and moving towards virtualization will trigger reduction in environmental impact of the growing use of computing
