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.

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.

A comprehensive study of gorvara puta in preparation of rasa bhasma

Ayurvedic formulations are of three types, Herbal, Mineral and Herbo-Mineral. Of which, Herbomineral is prepared either by Khalweeya or by Bhasmeekarana procedures. The quality of Bhasma depends on the number of putas given. Rasa Bhasma is one such kind of a Herbo-mineral preparation which can be obtained by Puta procedure as described in texts of Rasa Shastra. Though there are different procedures mentioned for preparation of Rasa Bhasma, maarana done with Gorvara puta seems to be an apt way to obtain the final product. Puta is the generalised way of heat application used during the pharmaceutical procedures of Rasa dravyas, where the purified organic Metal/Mineral is converted completely into powder form which can be absorbed easily into the body without causing any ill effects. Different types of Puta have been explained for bhasmeekarana of different metals and minerals. Among them, certain putas have been mentioned where Mandaagni plays a crucial role in Maarana (Incineration). These Mandaagniputas are in use of preparing certain Bhasmas like ShilajitBhasma, HaratalaBhasma, GouripashanaBhasma, and PaaradaBhasma. As these drugs are having relatively low boiling and melting points when compared to other dravyas, and are easy to evaporate when exposed to high temperatures, they need a standardized quantum of heat by which they can be transformed into Bhasma. Gorvara puta is one such kind where agni plays a major role in the preparation of Bhasma. So, the present study A Comprehensive Study of Gorvara Puta in Preparation of Rasa Bhasmahas has been under taken.

A critical review on mode of action of ayurvedic formulations on jwara

Rasa aushadhis are known for their uniqueness in curing the diseases with a very low dosage. These formulations are divided into two types based on their mode of preparation i.e., Single drug and Compound drug formulations. Based on their origin, the drugs are divided into three types, Herbal, Mineral and Animal. Any of these two or three together is combined to make a compound formulation. Apart from these, the other major factor which is needed for a formulation is the Rasa Panchaka of a Drug. Many of the formulations are being prepared based on their availability, keeping their Rasa Panchaka and Samprapti vighatana in mind. These formulations are designed in such a way that two or more drugs will be having one common quality, or Opposite Qualities or an Antidote of a particular Vishadravya, which can help in curing the disease. So an attempt is made to Review Tribhuvanakeerti Rasa with its Probable mode of action.

In-silico drug design, synthesis, characterization and biological evaluation of 2-azetidinone derivatives for antileukemic activity

2-Azetidinone shows biological activities like anti-bacterial, anti-microbial activity, anti-tubercular activity, and anti-cancer activity. 2-azetdinone derivatives were synthesized by simple procedures. The first step is synthesis of benzohydrazide through nucleophilic substitution reaction between methyl benzoate and hydrazine hydrate. The above formed compound is then treated with substituted aromatic aldehydes in the presence of catalytic amount of concentrated hydrochloric acid with stirring for one hour to give benzohydrazone which results in the formation of Schiff bases.Schiff bases undergone cyclisation in the presence of chloroacetylchloride and diethylenediamine by using ethanol as a solvent upon stirring for 4 hour’s yielded 2-azetidinone derivatives. The in-silico anti-leukemic activity was determined by using the computational tools i.e. “PASS Online”, “AutoDock4.2” and “ADMET” properties by online software’s. Among these six derivatives compounds (AZT-6) was shown more activity when compared with the other five compounds.

Improvement of injection conditions for zone electrophoresis of proteins in capillaries coated with n, n-didodecyl-n, n-dimethylammonium bromide

Fused silica capillaries treated with N, N-didodecyl-N, N-dimethylammonium bromide was used in capillary electrophoresis to separate basic proteins using ammonium acetate as BGE at pH 4.0, 70 mM. This surfactant forms a semi-stable coating that provides a strong anodic electroosmosis; however, such coating must regularly be regenerated to maintain efficiency and reproducibility. The temporal stability of the coating was greatly improved by a new procedure as described in previously study by our group. In this study, it is found such experimental conditions that the starting zone could be enriched without loss of sample. The injection of a short plug of the BGE diluted 100 times for 3 sec in 50 µm i.d. capillaries behind the sample zone at 15 kV gave the best performance, whereas, a plug of lower dilution degree (10 times) in 25 µm i.d injected for 3 sec at the same field strength gave the optimum results for this dimension. In conclusion, those conditions were found to effectively decrease the loss of sample and to give a higher separation performance in regard to peak efficiency and resolution compared to injecting the sample without a plug.

Recent approches of" impurity profiling" in pharmaceutical analysis: a review

Impurity is something that is impure or makes something else impure. An impure substance may be defined as follows: a substance of interest mixed or impregnated with an extraneous or usually inferior substance, from the standpoint of its usage, the drug substance is compromised in terms of purity even if it contains another material with superior pharmacological or toxicological properties. The impurity may be developed either during formulation, or upon aging of both API’s and formulated API’s in medicines. The presence of these unwanted chemicals, even in small amount, may influence the efficacy and safety of the pharmaceutical products. The impurities are not necessarily always inferior. Highly sophisticated instrumentation, such as mass spectra meters attached to a Gas Chromatography or HPLC, are inevitable tools in the identification of minor components (drugs, impurities, degradation products, metabolites) in various matrices. Present article reveals different impurities found in the API’s, methods for identifying them and the possible measures to deal with the interferences caused by them in pharmaceutical analysis.

Quality control of selected cosmetics marketed in libya for traces of toxic heavy metals: urgent need of guidelines harmonization

Heavy metals and trace elements such as lead (Pb), mercury (Hg), cadmium (Cd), arsenic (Ar), nickel (Ni), Chromium (Cr), cobalt (Co), copper (Cu), mercury (Mg), iron (Fe) and aluminum (Al) are detected in various types of herbal cosmetics. Heavy metals and elements can accumulate at high concentrations causing serious risks to human health when consumed. In this study, the levels of potential heavy metals of Pb, Ar, Cd, and Ni were quantitatively determined using atomic absorption spectroscopy. Samples of Henna leaves, Henna paste, Khol stones and baby Talcum powder were collected randomly from different public markets of Tripoli city. The results were evaluated by using different international guidelines, US-FDA, EU regulation, German (BVL), World Health Organization (WHO) and Canadian Guidelines. Because of controversial global guidelines, the study urgent the ultimate need for setting up harmonized minimum levels of heavy metals in cosmetics that could be applicable worldwide. Generally, the presence of a higher concentration of some of the studied heavy metals was observed, and the effect of these heavy metals at higher levels will be more harmful to consumer health after prolonged usage. In conclusion, nationally, the need for developing and updating the national specification for cosmetics by the Libyan National Centre for Standardization and Metrology (LNCSM) to protect consumers from more catastrophic cosmetic hazards is urgently required.
