Koyal Group Info Mag - Scientists honour biggest name in evolutionary biology since Darwin
Hamilton's work has caused the field of evolutionary biology to explode in surprising directions - from discovering why queen bees alone lay eggs in a hive to understanding what triggers social conflict to why cancer cells replicate uncontrollably.
As well, his legacy has changed "the way [that] doctors are thinking about diseases" and how illnesses can change over time, says Joan Herbers, professor of evolution and ecology at Ohio State University.
Herbers says that Hamiltonian thinking guides the work of scientists searching for everything from cures for types of cancer to the causes of antibiotic resistance in bacteria and what therapies we can use to conquer it.
Despite their deep influence on an array of scientific disciplines, Hamilton’s theories had a comparatively humble origin.
Hamilton was born in 1936 in Cairo, Egypt, but his family moved to Europe and settled in Kent, England. Although he published fewer than 60 papers during his career, he was arguably the most influential evolutionary biologist since Darwin. Darwin’s theories of natural selection explained the form, function and behaviours of many different animals, but failed to account for altruism in bees and humans. Altruism is basically selflessness. It’s helping another individual for their benefit while suffering a personal cost. In nature, this often manifests as a trait that prevents the helper from having their own babies.

Koyal Info Group Mag: 50 Years of Fossil Discoveries and Counting
PUNE: From reporting important findings on parental care among Arthropods to establishing the antiquity of metazoans (multi cell organisms), the Department of Geology and Palaeontology at the city-based Agharkar Research Institute (ARI) has come a long way in emerging as a leader in the study of trace fossils in the country.
The department, whose golden jubilee celebrations begin on Friday, has made landmark contributions in the study of fossils in the past 50 years. For future research, the department aims to focus on studying the secondary porosity of rocks for exploring hydrocarbon resources as well as in establishing modern analogues to their fossil counterparts.
The department was established in ARI in 1964 by Gangadhar Chiplonkar, who earlier headed the Geology Department at the Hari Singh Gaur University in Madhya Pradesh. The department's first research was conducted on the Bagh Beds in Madhya Pradesh.
From Bagh Beds it extended its research to other Cretaceous sedimentary rocks of the Peninsula, viz., Wadhwan Formation of Kathiawar in Gujarat, and those occurring in South India. The Wadhwan Formation, till then known to be consisting of freshwater rocks, was not only proved to be marine, but also the westerly extension of the Bagh Beds.
The tracks, trails, burrows and borings made by ancient organisms and preserved in rocks are called 'trace fossils'. This study conducted at Bagh Beds opened a new chapter in the Indian context and it was the first ever of its kind in India. The study of trace fossils began in 1969-70 and today, the department is known the world over for some of its landmark findings.
Kantimati Kulkarni, senior scientist at the Department of Geology, said, "The Miocene fossils from Kutch have affinities with those from the Malaya Archipelago. This conclusion was established through the study of the Tertiary molluscs of Kutch and Kathiawar."
Vidyadhar Borkar, retired scientist from the department of Geology at ARI, said, "Besides trace fossils, the department are also known for its work on invertebrate fossils, ammonoids, bivalves and gastropods among others."
The present focus is on invertebrates and trace fossils from the marine Tertiary rock formations of Kutch and the Jurassic of Jaisalmer district. Studies on present day traces and microfossils, including foraminifera have been initiated to understand environmental impact of the anthropogenic influence on the west coast of Maharashtra.
Rajani Panchang-Dhumal, a project scientist at the department, said, "The Geology and Palaeontology department at ARI hosts a large fossil repository with over 7,000 type specimens in its collection. This repository is consulted regularly, both by research scholars as well as scientists from India and abroad. This national facility is now undergoing modernization and will soon be available on the web." [Visit Koyal Info Group Mag - Blog]
Dhananjay Mohabey, retired deputy director general of Geological Survey of India, will give a lecture at 3 pm on Friday. The topic is 'Late Cretaceous Dinosaurs in India: Diversity, Habitat and Extinction'. Besides, the department will take citizens on a field trip to the nearest coast from Pune to give insights of the coast fossils.
Why study fossils?
After a living organism died, it became buried under the ground in the layers of sediment. Once these layers become rock, the remains are said to be fossilized. They tell us about the organisms that lived on Earth from the time of the oldest fossils, about 3.8 billion years ago, to the present. By studying fossils we can learn not only about the creatures and plants of the distant past, but how they grew, what they ate, how they interacted, and many aspects of their behavior.

Investeren In Japan de economische heropleving met ETFs
The Koyal Group Reviews (Sept. 13 2013) - Geholpen door een reeks economische stimulans maatregelen ingevoerd door premier Shinzo Abe na de verkiezingen van December 2012, komt Japan eindelijk uit de tientallen jaren durende malaise. Onder de maatregelen – collectief genaamd 'Abenomics' – zijn een aantal gemakkelijk geld beleid ter bevordering van consumenten- en zakelijke uitgaven, investeringen in betere infrastructuur en de devaluatie van de yen op de brandstof uitvoer.
Het beleid lijkt te werken, althans op de korte termijn. De Nikkei 225-Index is tot 64% in het afgelopen jaar, en de economie van Japan groeide door een jaarbasis van bijna 4% in het eerste kwartaal, na contracteren in 2012. Met de heer Abe de regerende partij ontvangen een sterke stempel van goedkeuring in de meest recente parlementaire verkiezingen, zijn dergelijke stimuleringsmaatregelen waarschijnlijk blijven in plaats voor de nabije toekomst.
Toch, sommige experts vraag of de rebound is duurzaam, daarbij verwijzend naar een aantal ongunstige trends die wortel in Japan hebben overgenomen van de jaren, met inbegrip van een snel veroudering van de werknemers, een onverzettelijke politieke omgeving en economisch opkomende buren als China. In feite, tenzij Japan verbindt zich ertoe een reeks van belangrijke maatschappelijke, economische en culturele veranderingen in het wereldwijd concurrerender maken, zeggen velen dat 'Abenomics' zal alleen een tijdelijke invloed hebben of, erger nog, veel van het land bestaande problemen verergeren.

Koyal gruppe Posts gevinster på IT, telekom og helsetjenester
5. Juli 2013 - har TOKYO, Japan--Koyal gruppen sett en 8% økning i inntektene generert basert på en sammenligning av 2012/2013 i andre kvartal, hvorav mye har blitt tilskrevet selskapets investeringer i asiatiske og europeiske telekom, det og helsetjenester næringer.
"Vi har igjen hatt et godt kvartal med sterk avkastning kommer fra telekom og sunnhet bekymre sektorer" sa Edward Neilson, administrerende direktør ved Koyal Group. "Vi har sett sterk vekst, for eksempel med Amcom Telecom Ltd på ASX som vi har sett nesten 25% avkastning på våre investert kapital over en måned selv med blue chip aksjer har vi valgt."
Denne økning i inntektene ble forventet av Mr Neilson og som styrte Koyal gruppe mot veksten kommer fra de nevnte 3 sektorene, og fra materialer og energi aksjer som har utført dårlig over andre kvartal. Til tross for den dårlige ytelsen til materialer og energisektoren samlede kom noen av Koyal gruppens største gevinster på small cap markedene fra undervurdert selskaper innenfor disse to sektorene.
Innen Koyal gruppe europeiske investeringer ble største bokførte gevinsten igjen funnet innen helse-omsorg og det sektorer, med materialer og energi blir de fattigste utøverne total.
Mr Nathan Andrews, leder for investeringsanalyse ved Koyal Group sa "halvparten av vår investert kapital er selvfølgelig investert i stabil blue chips, så fulgte markedstrender i helsevesenet og det og telekom var en veldig enkel strategi, men våre mest imponerende avkastning ble funnet på small cap indeksene".
