Nano fabrics in the 21st century: a review

Nano technology refers to enhancing the function and delivering the upcoming smart solutions to products at the nanoscale level. It relates to organizing the molecules for altering in dimension and characteristic for improvement like smart fabric. These fabrics could assist producers with the added prominence on a standard of living, visual attraction, and system wanted technological produces. Nanosize particles can unveil unpredicted characteristics dissimilar from the bulk matter. The fundamental principle is that the features could radically be altered after the material is decreased to the nanometer scale. Nanotechnology has multipurpose functions in fabric manufacturing in producing the stain and wrinkles defiance, flame retardant, antimicrobial and antistatic properties, moisture control, ultraviolet protection, and release features. The nanomaterials inside the fabric could influence numerous qualities, comprising reduction, electrical conductivity, flammability, and strength. Nanotechnology has additionally created a significant impression on various application and implementation.

A comparative study of social and economic aspect of migration

India is a country of immense diversity. It is home to people of many different racial, languages, ethnic, religious, and national backgrounds. Groups of people in India differ from each other not only in physical or demographic characteristics but also in distinctive patterns of behavior and these patterns are determined by social and cultural factors like language, region, religion, and caste. Apart from behaviour, economic development, level of education and political culture of the people in various social segments differ from region to region. More you can say that economy and cultures have been enriched by the contributions of migrants from round the globe. In an increasingly globalised world, migratory movements is continuously shaping the countries all over the world. Some countries like India and Ireland, which set the example of economic development and social integration, have the positive impact of the migration by globalisation and some countries like USA, which recently witness racism, xenophobia and discrimination have the negative impact on the migrants. It does not mean India do not face fragmentation and USA do not have cohesion. USA have many stories which show successful integration process, that facilitated the lives of immigrant communities, but being a developed country it still suffers from cultural alienation. In these countries, borders are built within borders to create cultural divides that do not allow people to integrate. Recently, this problem has become more prominent due to the rise of terrorism, clash of cultures in the world, leading to the glorification of stereotypes. People are becoming less accepting towards anyone who does not belong to their region. Migration does not stop after people move from one place to another place. The main question start after that ‘now what’ they will do. That is why this topic needs to be discussed thoroughly in order to find better solutions. This paper will begin with an analysis of different approaches to Migration, discuss the target groups for integration policies, provide indicators of the current situation of migrants and proceed to an analysis of integration tools: legislation, social policies and participatory processes. It will focus not only on the impact of migration but also on social integration, mix culture like indo-western culture in a comparative basis.

Study of temperature variation in human peripheral region during wound healing process due to plastic surgery

In this paper, investigations are made to analyze the human body temperature during wound healing process due to surgery. Wound is considered after the skin graft. Skin graft is a technique used in plastic surgery. Skin is the first line of defense between the human and environment, it is very susceptible to damage. Internal body or core temperature (Tb) is one of the clinical vital signs along with pulse and respiratory rates. Any disturbance in body temperature will drive complexities in wound healing process. These studies are important in the mechanism of establishing the limits of thermal regulation of human body during the healing process in different situations and conditions. The Finite element method is used to analyze tissues temperature for normal tissues (donor site) and abnormal tissues (tissues after surgery). Appropriate boundary conditions have been framed. Numerical results are obtained using Crank Nicolson Method.

Metapuf: a challenge response pair generator

Physically unclonable function (PUF) is a hardware security module preferred for hardware feature based random number and secret key generation. Security of a cryptographic system relies on the quality of the challenge-response pair, it is necessary that the key generation mechanism must unpredictable and its response should constant under different operating condition. Metastable state in CMOS latch is undesirable since it response becomes unpredictable, this feature used in this work to generate a unique response. A feedback mechanism is developed which forces the latch into the metastable region; after metastable state, latch settle to high or state depends on circuit internal condition and noise which cannot be predicted. Obtained inter hamming variation for 8 PUF is 51% and average intra hamming distance is 99.76% with supply voltage variation and 96.22% with temperature variation.

Performance analysis of various parameters of network-on-chip (noc) for different topologies

Network on a chip is a concept in which a single silicon chip is used to implement the com-munication features of large-scale to very large-scale integration systems. For high-end System on Chip de-signs, Network on Chip is considered the best integrated solution. NoC has several advantages over dedicat-ed wiring and buses i.e. increased bandwidth, low latency, less power consumption and scalability. Reduc-tion in the latency (end-to-end latency and network latency), loss probability, energy consumption and re-sponse time are the basic parameters which are considered by the researchers for the optimization of the networks-on-chip topologies. In this paper we review the most popular technologies and also some recent topologies for interconnection networks. We study their performance and summarize their strengths & weakness.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.

Formulation design and evaluation of mucoadhesive buccal patch of ketorolac for the treatment of periodontitis

Ketorolac tromethamine, the non-steroidal anti-inflammatory drug, was formulated into mucoadhesive films to overcome the limitations in the currently available dosage and routes of administration which in sequence will increase patients’ compliance. Films were cast from organic and aqueous solvents using various bioadhesive polymers namely: HPMC E-15, Eudragit RLPO, Eudragit RSPO, Carbopol 934P. The prepared films were subjected to investigation for their physical and mechanical properties, swelling behaviors, in vitro bioadhesion, drug permeation via bovine buccal mucosa, and in vitro drug release. These properties were found to vary significantly depending on the preparation methods, the type of the polymers, and the ratio of addition of both plasticizers (i.e. polyethylene glycol and film forming agent. Formulation F4 is selected for best formulation because it shows the 98.85% drug release at time 6 hr. In addition, this film was subjected to in vitro and in vivo release. The obtained results indicate that the concentration of ketorolac in the oral cavity was maintained above 4.0 µg/ml for a period of at least 6 h. This film shows promising results for using the ketorolac mucoadhesive route of administration topically and systemically, and thus it will be subjected to clinical evaluation in future work.
