By: Prem Jose Vazhacharickal,Anand Joshy,Akshay Hari

Nanotechnology is an emerging field of science. It has increased applications in diverse area for the development of new materials at nanoscale levels. Synthesis of nanoparticles using biological methods is referred as greener synthesis of nanoparticles. Green synthesis provides advancement over chemical and physical method as it is cost effective, environment friendly, and safe for human therapeutic use. Stingless bees are highly social (eusocial) insects which populated the tropical earth 65 million years ago longer than honey bees. Among the most common uses of stingless bee honey are to treat stomach disturbance, cough, tonsillitis, sore throat, stomach and intestinal ulcers, cold, disease of the mouth, mucus membrane, and as a wound dressing due to its antimicrobial activity. Stingless bees honey were used to for the green synthesis of silver nanoparticles. Antimicrobial activity of the green synthesised nanoparticles were tested used agar diffusion method against Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Klebsiella pneumoniae. The results showed that stingless bee honey could be effectively used for the synthesis of silver nanoparticle. The synthesized silver nanoparticles shows antibacterial activity on both Gram positive and Gram negative bacteria. This biosynthesis of nanoparticles is cost efficient, pollutant free and simpler to synthesize.

Sustainable Horticulture Development and Nutrition Security (Vol. 3)

By: Prem Nath

We all are indebted to nature for providing us food and its resources for our subsistence and survival. In the food domain, cereal and legume grains occupy the front line, whereas, horticultural crops have occupied the second line of defense. For healthy diet cereals and legumes provide us with carbohydrates and protein, whereas, fruits and vegetables provide us minerals and vitamins. Both macro- and micro- nutrients are essential for human growth and development. The fruits and vegetables are the major source of micro-nutrients. It is estimated that up to 2.7 million lives could potentially be saved each year if fruit and vegetable production was sufficiently increased. Both at national and international levels, food and agriculture/horticulture development plans and estimates are basically developed, framed and implemented, and narrowed down to cereal production. In the present context of attaining nutrition security, this mode of thinking on ‘food’ needs to be changed to ‘nutrients’, which will include necessarily all those crops including fruit and vegetables which provide all macro- and micro-nutrients to ensure balanced nutrition needed for good human health. The present publication has attempted to reflect and discuss the above views and ideas on the subject of sustainable horticulture development and nutrition security in nine chapters with 32 articles by 32 authors.

Panajpur Express

By: Prem L. Nain

1935, a British-ruled India: When hardly any legal practitioners of Indian origin were allowed to practice, Paresh Rastogi, a young and righteous lawyer, arrives in the quaint town of Panajpur to set up his own legal practice. But soon, he is met with racist judges and uncooperative government officials who want to make his life very difficult. Being new in town, Paresh faces jealousy, contempt and even hatred from several senior lawyers who find his honest ways a threat. The cases that appear simple at first, take him through a trail of twists and turns, making him look deeper and dwell into his own values. Not only does Panajpur present itself with an unseemly animosity towards Paresh, but also makes him encounter with corrupt and power-hungry people. This honest lawyer is challenged again and again and torn apart on the decision of siding with the right or the wrong, while the line between the two keeps blurring. Will Paresh be able to stand against all adversities of the new town or will he become the very thing he hated?

An Epic Life

Ramanand Sagar: From Barsaat to Ramayan

By: Prem Sagar

On 25 January 1987, with the telecast of the very first episode of Ramayan, Indian television changed for all time to come. In a matter of weeks, the series became a national obsession. During the Ramayan slot, roads emptied out. No marriages and political rallies were scheduled for that time. More than three decades later, there has been nothing to match it. Ramanand Sagar, the man behind the phenomenon and a successful filmmaker from Bombay, was among the first to recognise the immense power of television. He first made his mark as a writer in Raj Kapoor's Barsat (1949). From 1961 to 1970, Sagar wrote, produced and directed six consecutive silver jubilee hits-Ghunghat, Zindagi, Arzoo, Ankhen, Geet and Lalkar. An Epic Life: Ramanand Sagar, From Barsaat to Ramayan, written by his son, Prem Sagar, an award-winning cinematographer, is an intimate look at the life of a visionary. It traces Sagar's life from his birth in Kashmir in 1917, his dramatic escape in 1947 when Pakistani tribesmen attacked the state, his arrival in Bombay and his subsequent glorious career-the crowning achievement of which was the smashing success of Ramayan.

The Politics of Counterterrorism in India

Strategic Intelligence and National Security in South Asia

By: Prem Mahadevan

In the wake of the Mumbai terrorist attacks in November 2008, terrorism and counterterrorism in India became the focus of international, regional and national attention. Here, Prem Mahadevan, by using three case studies of Sikh separatist, Kashmiri separatist and pan-Islamist groups, focuses on the efforts of India's decision-makers and intelligence agencies to create coherent and effective counterterrorism policies and actions. Questioning why Sikh separatist groups have been effectively contained, and yet pan-Islamists have not, Mahadevan draws the conclusion that, due to a gap between the expectations of decision-makers and the capabilities of strategic intelligence agencies, India's ability to prevent terrorist attacks has been undermined. In addition, the role played by Pakistan's intelligence agencies in the border regions is given extensive analytical treatment. Combining a theoretical approach with empirical analysis of India's counterterrorist activities, this book holds valuable information for those examining strategy-making and counterterrorism - practitioners as well as researchers - in addition to those interested in the politics of India.

RAPD, Antimicrobial and Anticancer Activity of Musa Varieties in Kerala

By: Anu Augustine,S Geethalakshmi ,Prem Jose Vazhacharickal,P. E Sreejith,M. Sabu

Banana is one of the most important food crops all over the world. There are around 365 varieties of bananas available throughout the world. Banana is a traditional medicine for diabetes, cancer, diarrhoea and also highly nutritional food crop. In this study, commonly used varieties of banana are taken for characterization by morphology and genotype which is based on International Plant Genetic Resources Institute and RAPD analysis. Five varieties were morphologically similar in parameters such as leaf habit, pseudo stem appearance and peel color. RAPD analysis proved that these varieties of banana are closely related which coincides with the morphological characterization. Also, this study is aimed at examining the anticancer activity of Musa acuminata variety of banana which is commonly consumed in southern part of India. Anticancer examination of the sample was performed for the hexane extract using DLA and MG-63 cell lines which showed a high degree of anticancer activity which was proved by the cytotoxic effect on the tumor cell lines. Phytochemicals present in the plant concentrate provoked cell apoptosis and smoother cell expansion to quickly partitioning malignancy cell lines. Among the five varieties analysed, Musa accuminata Colla variety shows increased level of anticancer activity in both cell lines. So it is anticipated that this variety can be used as medicine orally for cancer treatment.

Occurrence of a new type of stingless bee in Kerala. Evidence from morphometric analysis

By: Prem Jose Vazhacharickal,Sajan Jose K.

Scientific Study from the year 2016 in the subject Biology - Zoology, , language: English, abstract: Stingless bees are limited to tropics and subtropics with diversity in species and share morphological and behaviour patterns. Stingless bees are major pollinators of flowering plants in the tropics and improve crop productivity. Trigona iridipennis Smith were kept in India for centuries for the high medicinal value of honey as well as propolis and bee wax. A wide range of variations, especially worker and drone body size and measurement, were reported. Morphometric and geometric analysis provide a valuable tool for the differentiating variations among various honey bees and stingless bees. Based on these back ground, our objectives of this study were 1) to characterize the morphometric aspects of workers in this reported new species of stingless bees and 2) to identify the various similarities and differences existing based on factor and principal component analysis with Trigona iridipennis Smith. A total of 30 samples of workers were collected and various morphometric characters including head length (HL), head width (HW), proboscis length (PL), distance between two dorsal ocelli/lower intercocular distance (DBO), dorsal ocello-ocular distance (DOOD), antennal length (AL), thorax femur length (TFL), thorax tibia length (TTL), thorax metatarsus length (TML), thorax metatarsus width (TMW), thorax forewing length (TFWL), thorax forewing width (TFWW), pterostigma width (PtStW), pterostigma length (PtStW), hind wing length (HWL), hind wing width (HWW), number of hamuli (HAM), abdominal tergite length (AbTL), abdominal sternum width (AbSW), mandible length (MdL) and mandible width (MdW), head length width ratio (HLW), thorax metatarsus length width ratio (TMLW) and thorax forewing length width ratio (TFWLW) were analyzed. One sample (SS1) showed distinct differences in habitat preference (Laterite rock), appearance (size and colour), behaviour (passive) and nest architecture (narrow round entrance tube, snow white brood, cream white food pots). The present study based on the morphometry of stingless bees across Kerala shows that, in spite of the morphological and behavioural variations exhibited by the bees, members of all samples belong to Trigona iridipennis. But one sample (SS1) shows entirely different morphometric characteristics. It was found that this sample belongs to genus Lisotrigona

Morphometric characterization of stingless bees (Trigona iridipennis Smith) in Kerala

An overview

By: Prem Jose Vazhacharickal,Sajan Jose K.

Scientific Study from the year 2014 in the subject Biology - Zoology, , language: English, abstract: The major species of stingless bees in Kerala is Trigona iridipennis Smith which are easy to domesticate due to low temperament and easy adaption to various habitats. Little is known about the variations that exist among them. We therefore conducted morphometric studies among workers and drones across 14 districts in Kerala with a view to characterize them. A total of 188 and 71 samples of drones and workers collected and analyzed various morphometric characters including head length (HL), head width (HW), proboscis length (PL), distance between two dorsal ocelli/lower intercocular distance (DBO), dorsal ocello-ocular distance (DOOD), antennal length (AL), thorax femur length (TFL), thorax tibia length (TTL), thorax metatarsus length (TML), thorax metatarsus width (TMW), thorax forewing length (TFWL), thorax forewing width (TFWW), pterostigma width (PtStW), pterostigma length (PtStW), hind wing length (HWL), hind wing width (HWW), number of hamuli (HAM), abdominal tergite length (AbTL), abdominal sternum width (AbSW), mandible length (MdL) and mandible width (MdW), head length width ratio (HLW), thorax metatarsus length width ratio (TMLW) and thorax forewing length width ratio (TFWLW). Our studies revealed that most of the worker morhopometric characters were positively correlated across all the districts in Kerala. However, there is not much significant differences among drones across various districts. Based on our studies, even though we detected significant differences among worker morhphotmetry we could not to find distinguishing and remarkable differences among collected samples. They may be interpreted as nutritional, seasonal and climatic factors.

Green synthesis of copper and zinc nanoparticles from plant extracts and evaluation of their antifungal activity against Fusarium oxysporum cubense: an overview

By: Prem Jose Vazhacharickal,Nissy Mary Joseph,Sajeshkumar N.K,Jiby John Mathew,P. E Sreejith,M Sabu

Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various natural plant leaves of Chromolaena odorata, Justicia adhatoda, Glycosmis pentaphylla, Azadirachta indica, Gliricidia sepium, Piper nigrum, Ocimum tenuiflorum and Tabernaemontana divaricate. Nanoparticles are small particles with a dimension of 10-9 and 10-10. Green synthesis is a new method developed for the synthesis of nanoparticles which is small in size, large surface area and eco- friendly. Leaf extracts of these plants were used for synthesis of copper and zinc nanoparticles, as nanoparticles are powerful antimicrobial agents. The extract is prepared with a stock solution of 100mM copper sulphate and 100mM zinc sulphate. The leaf extracts were prepared with 5 solvents (Distilled water, Propane, Hexane, Acetone and Methanol). The action of plant leaves were observed by the zone of inhibition obtained with a concentration of 50, 100 and 150µl respectively. The result was more in copper nanoparticles of leaf extract as compared to the zinc nanoparticles of particular leaf extracts but the zinc particles with methanol and propane showed good result with particular leaves. In dried condition of leaves copper nanoparticles with propane as solvent exhibited a greater zone of inhibition. Moreover the solvent, methanol showed good results with both zinc and copper nanoparticles. The synthesized nanoparticle were characterized by UV-VIS spectrophotometry to confirm the formation of nanoparticles. Green synthesis is used namely because of low cost, simple, use of less toxic materials, most important is eco-friendly.

Efficient in vitro callus induction protocol for three endemic medicinal plants (Cyclea peltata, Naegamia alata and Kaempferia galangal Linn.) in Kerala

By: Prem Jose Vazhacharickal,Noby Mathew,Lakshmi B Nair

A simple and reproducible protocol for in vitro callus induction from explants of three endemic plants (Cyclea peltata, Naregamia alata and Kaempferia galanga Linn.) have been developed. Explants collected from the field grown plants were cultured on MS medium supplemented with different concentration/combination (s) of phytohormones. During the study period we evaluated the effect of different growth regulators in callus induction and its morphological analysis of the targeted plants. To optimize the callus induction of three different targeted explants were cultured on different concentration phytohormones. Among which the system include 2,4-D has the most efficient effect on the three experimental plants, Five different concentration taken for three explants, among that Cyclea peltata and Kaempferia galangal Linn. has the highest potential to induce callusing at 2 mg/L of 2,4 -D. In this study we found that there was no effect on callusing of the targeted plants was MS medium containing combination of auxin and cytokinin for callusing.

Morphological diversity of jackfruit (Artocarpus heterophyllus) varieties in Kerala

By: Prem Jose Vazhacharickal,Sajeshkumar N.K,Jiby John Mathew,Alen N Albin

Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. Jack fruit has diverse medicinal uses especially as anti-oxidant, anti-inflammatory, antimicrobial, anti-cancer and anti-fungal agent. Jackfruit is considered to be an underutilized fruit where most of the fruits get wasted due to ignorance, lack of post-harvest technology and gaps in supply chain systems. Jackfruit contains more protein, calcium, iron, vitamins and other essential nutrients, compared to common fruits. To find out the morphological variations among jackfruits in Kerala we conducted an elaborate survey and found out varieties using parameters such as tree characteristics, leaf characterises, fruit characteristics of selected samples as measure. Both qualitative and quantitative data were measured using field visit and standard methods and morphological indicators. After analysis of data morphological variations among the jack fruit samples were identified. This includes the morphological difference between fruit stalk leaf and branch leaves. In the fruits themselves, colour, shape and size are also found to vary among the samples. These variations may have some relationship to climatic factors such as rainfall, pH and soil properties. Morphological variations affect the selection of the varieties. Encouragement should be given to the marketing as well as creation of value added products from this underutilized fruit tree.

Green synthesis of copper and zinc nanoparticles using different varieties of banana starch, latex and sap and evaluation of their antifungal activity against Fusarium oxysporum cubense

By: Prem Jose Vazhacharickal,Ellamplackill Surya Santhosh ,Sajeshkumar N.K,Jiby John Mathew,P. E. Sreejith,M. Sabu

Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various banana parts mainly its peel, pulp sap and its latex of varieties such as Robusta (B1) Musa acuminate Colla (AAA), Etha (B2) Musa x paradisiaca (AAB), Poovan (B3) Musa x paradisiaca (AAB), Sundari (B4) Musa acuminate Colla (AA), Njalipoovan (B5) Musa acuminate Colla (AB), Palayamkodan (B6) Musa x paradisiaca (AAB), Kannan (B8) Musa acuminate Colla (AAA), Pachakadali (B9) Musa acuminate Colla (AAA). Nanoparticles are small particles with a dimension of 10-9 and 10-10. Green synthesis is a new method developed for the synthesis of nanoparticles which is small in size, large surface area and eco- friendly. Leaf extracts of these plants were used for synthesis of copper and zinc nanoparticles, as nanoparticles are powerful antimicrobial agents. The results shows that dry skin and fruit extracts of Palemkodan, Njalipoovan, Etha, Pachakhadali with solvents, propane, ethanol, methanol and acetone and the fresh extract latex and sap of Palemkodan and Poovan with solvents isoproponol, ethanol, methanol with 1/10 and 1/50 dilution are used for the synthesis of copper and zinc nanoparticles. Copper and zinc nanoparticle shows greater antifungal activity than copper sulphate and zinc sulphate, respectively and dry extract. The maximum zone of inhibition was at 50 and 100 µl for all the test plates. This indicates that the zone of inhibition increases with as the concentration of nanoparticles increased. An overall result showed that ethanol, methanol and isoropane could be used as a good solvents and skin of Njalipoovan and Etha could be used for controlling the Fusarium oxysporum cubense under invitro conditions.

Agricultural Growth, Productivity and Regional Change in India

Challenges of globalisation, liberalisation and food insecurity

By: Surendra Singh,Prem Chhetri

Agriculture productivity, growth and regional change in post-colonial India from a spatial perspective are yet to be rigorously examined. In particular, the impacts of economic liberalisation, globalisation and deregulation are not being empirically investigated at a small-area level using advanced statistical and spatial techniques. Understanding the process of regional formation and the rapid transitioning of agricultural landscapes in the Post-Liberalisation phase is pivotal to developing and devising regional economic development strategies. This book employs advanced methods to empirically examine the key characteristics and patterns of regional change in agricultural growth and productivity. It offers insights on changes in agricultural production and practices since the colonial period through to the Post-Liberalisation phase in India. It also incorporates the key public policy debates on the progress of India’s agricultural development with the aim of formulating spatially integrated strategies to reduce rapid rise in the regional convergence and to promote equitable distribution of strategic government investment.

Islamism and Intelligence in South Asia

Militancy, Politics and Security

By: Prem Mahadevan

State sponsorship of terrorism is a complex and important topic in today's international affairs - and especially pertinent in the regional politics of the Middle East and South Asia, where Pakistan has long been a flashpoint of Islamist politics and terrorism. In Islamism and Intelligence in South Asia, Prem Mahadevan demonstrates how over several decades, radical Islamists, sometimes with the tacit support of parts of the military establishment, have weakened democratic governance in Pakistan and acquired progressively larger influence over policy-making. Mahadevan traces this history back to the anti-colonial Deobandi movement, which was born out of the post-partition political atmosphere and a rediscovery of the thinking of Ibn Taymiyyah, and partially ennobled the idea of `jihad' in South Asia as a righteous war against foreign oppression. Using Pakistani media and academic sources for the bulk of its raw data, and reinforcing this with scholarly analysis from Western commentators, the book tracks Pakistan's trajectory towards a `soft' Islamic revolution. Envisioned by the country's intelligence community as a solution to chronic governance failures, these narratives called for a re-orientation away from South Asia and towards the Middle East. In the process, Pakistan has become a sanctuary for Arab jihadist groups, such as Al-Qaeda, who had no previous ethnic or linguistic connection with South Asia. Most alarmingly, official discourse on terrorism has been partly silenced by the military-intelligence complex. The result is a slow drift towards extremism and possible legitimation of internationally proscribed terrorist organizations in Pakistan's electoral politics.
