The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models
Open Access for the Medical Librarian
No full textThe most important aspects of open access for the medical librarian are presented. Reasons for open access include access to research information, access to taxpayer-funded research, facilitation of evidence-based medicine, equity of access, promotion of author control, and controlling library costs. The two primary approaches to open access, via author self-archiving and open access publishing, are presented. Key open access policy developments are highlighted. Many of the major policy initiatives of the moment are from the research funders. From the researcher funders' point of view, open access means more research impact, more real-world impact when professionals can access the literature, and value is illustrated to the taxpayer, building support for further research funding. The world's largest medical research funders, including the U.S. National Institute of Health and the Wellcome Trust, have public access policies, and many more policies are in development. For example, two weeks ago the Federal Research Public Access Act was introduced in the U.S. Senate. One of the essential elements of open access policy is ensuring that researchers are required, not requested, to deposit works. In Canada, the Canadian Institutes of Health Research has a policy in development called Access to Products of Research; public comments are due May 15, 2006. The dramatic growth of open access - over 2,220 journals in DOAJ, over 7.3 million items in an OAIster search - is discussed, as is the idea of new roles for librarians in an open access environment
Transfer principles, Fenchel conjugate and subdifferential formulas in Fan-Theobald-von Neumann systems
No full textA Fan-Theobald-von Neumann system is a triple (V,W,λ), where V and W are real inner product spaces and λ:V→W is a norm-preserving map satisfying a Fan-Theobald-von Neumann type inequality together with a condition for equality. Examples include Euclidean Jordan algebras, systems induced by certain hyperbolic polynomials, and normal decomposition systems (Eaton triples). The present article is a continuation of an earlier paper, where the concepts of commutativity, automorphisms, majorization, and reduction were introduced and elaborated. Here, we describe some transfer principles and present Fenchel conjugate and subdifferential formulas.The work of J. Jeong was supported by the National Research Foundation

MD Family Medicine - Calicut experience: History is made here
No full textGovernment Medical College, Calicut, Kerala - the first medical college in India to start Doctor of Medicine (MD) in family medicine as a postgraduate course. This was in the year 2012. Till date, this is the only medical college to have MD Family Medicine program in India. The college was allowed two MD Family Medicine seats per year by the Medical Council of India, and this is a 3 year course. The first batch of MD Family Medicine students has passed out from the Government Medical College, Calicut in July 2015. In this article, the author, who has been working as an assistant professor in the Department of Family Medicine, ever since the department started in the year 2012, shares her experiences in setting up the department, its functioning and the achievement of bringing out the first batch of successful MD Family Medicine specialists. Another laurel, of which the institution is proud of, is that they were able to incorporate family medicine teaching program in the MBBS curriculum. A brief introduction about Government Medical College, Calicut, is also given

Study on Modular Lattice and Boolean Algebra
No full textThis thesis is submitted to the Department of Mathematics, Khulna University of Engineering & Technology in partial fulfillment of the requirements for the degree of Master of Philosophy in Mathematics, April 2008.Cataloged from PDF Version of Thesis.Includes bibliographical references (pages 85-86).This thesis studies extensively the nature of modular lattices and Boolean algebras. The modular lattices have been study by several authors including Abbott [2] , Birkhoff [ 3] and Rutherford [19 ]. A poset is said to form a lattice if for every a, b ϵ L, a ˅ b and a ˄ b exists in L, where ˅ , , ˄ are two binary operation . A lattice L is called modular lattice ifforall a,b,c ϵ L with a ≥b, a, ˄ (b ˅ c) = [b ˅ (a ˄ c)]. In this thesis we give several results on modular lattices which certainly extend and generalized many result in lattice theory. In chapter one we discuss ideals , complete lattices , relatively complemented lattices and other results on lattices which are basic to this thesis . If every interval in a lattice is complemented the lattice is said to be relatively complemented. Chapter two discusses Embeddings, Kernels and dual homomorphisms. If L, M be two lattices, a one-one homomorphism θ : L→ M is called an embedding mapping . Also in that case we say L is embedded in M. We prove that the definition of dual meet homomorphism and dual join homomorphism are equivalent.
In chapter three we discuss on modular lattices and distributive lattices Distributive lattices have been studied by sever author including Cignoli [ 4 ] , Cornish [ 5 ] , Cornish and Hicman [ 6 ] and Evans [ 7 ] Nieminen [15 ], [16] . Hence we prove a lattice L is distributive if and only if
(a ˅ b) ˄ (b ˅ c) ˄ (c ˅ a)=(a ˄ b) ˅ (b ˄ c) ˅ (c ˄ a) ˅ a, b, c ϵ L
In chapter four we discuss Boolean algebras and Boolean functions Previously Boolean algebras, Disjunctive Normal forms and Conjunctive Normal forms have studied by Abbott [ 1 ] . Here we extend several result on Boolean Algebras and also find the DN form of the function whose CN form is
f =(x ˅ y ˅ z) ˄ (x ˅ y ˅ z') ˄ (x ˅ y' ˅ z) ˄ (x ˅ y' ˅ z') ˄ (x' ˅ y ˅ z).Md. Rashidul IslamMaster of Philosophy in Mathematic
