Author and Owner Intersection in Sound Recordings in The Copyright Act of India
No full text245-250The present work focuses on the intersection of author and owner concerning sound recordings. The interpretation of copyright law on the author and owner intersection by the Court's are rather varied. It may be because the restricted issues at its hand lead the courts. More particularly, interpretation of provisos (b) and (c) of Section 17 of The Copyright Act, 1957 leads to differing interpretations by the Courts. The present analysis is made by studying three recent judgments to understand the author and owner conflicts of sound recordings
Regulation of the divalent metal ion transporter via membrane budding
No full textData source: Supplementary information, https://doi.org/10.1038/celldisc.2016.11The release of extracellular vesicles (EVs) is important for both normal physiology and disease. However, a basic understanding of the targeting of EV cargoes, composition and mechanism of release is lacking. Here we present evidence that the divalent metal ion transporter (DMT1) is unexpectedly regulated through release in EVs. This process involves the Nedd4-2 ubiquitin ligase, and the adaptor proteins Arrdc1 and Arrdc4 via different budding mechanisms. We show that mouse gut explants release endogenous DMT1 in EVs. Although we observed no change in the relative amount of DMT1 released in EVs from gut explants in Arrdc1 or Arrdc4 deficient mice, the extent of EVs released was significantly reduced indicating an adaptor role in biogenesis. Furthermore, using Arrdc1 or Arrdc4 knockout mouse embryonic fibroblasts, we show that both Arrdc1 and Arrdc4 are non-redundant positive regulators of EV release. Our results suggest that DMT1 release from the plasma membrane into EVs may represent a novel mechanism for the maintenance of iron homeostasis, which may also be important for the regulation of other membrane proteins.Kimberly D Mackenzie, Natalie J Foot, Sushma Anand, Hazel E Dalton, Natasha Chaudhary, Brett M Collins, Suresh Mathivanan and Sharad Kuma
Evaluation of efficiency of different decontamination methods of dental burs: An In vivo study
No full textIntroduction: Infection control is very important in dentistry. Both dentist and patients are at risk of communicating diseases during treatment procedures. Dental burs have been identified as a source of cross-contamination between patient and dental personnel. Aim: The present study was done to quantitatively and qualitatively assess the pathogenic contamination of dental burs used for tooth preparation and to determine the effective method of sterilization(autoclave,glass bead sterilizer, hot air oven and surgical spirit immersion) of burs used for crown preparation. Methodology: Dental burs were assessed before and after tooth preparation,also after sterilization burs were evaluated. Conclusion: Findings of our study revealed that among the experimental groups used in the present study, Autoclave and Hot air oven was found to be the relatively best method to sterilize burs. Proper cleaning and sterilization of burs should be strictly employed to prevent cross contamination in clinical practice
An Obsevational study on the Human Acetabulum in South Indian Fetuses and Adult Population
No full textAcetabulum (acetum - vinegar, abulum - saucer or cup) is a bony component of hip bone. Anatomical, evolutionary, Anthropological, Histopathological, Forensic, Orthopedic and Radiological significance of Acetabulum were analysed and the dissertation plot was designed based on the acetabulum.
In 100 dry hip bones, the acetabular diameter, acetabular depth, capacity of acetabulum and types of anterior acetabular ridge were observed. On statistical analysis ,there was significant difference observed in the morphometric parameters when it is based on gender , there was no significance when based on sides.
In 30 cadaveric hip bones the acetabular diameter, acetabular depth and capacity of the acetabulum were analysed.There was significant difference observed in the morphometric parameters when it is based on gender, there was no significance when based on sides.
In 105 Xray pelvis (AP view), the CE angle, AD, AA, AIA, RA, ARO, EI, LS, DTW, JSW and PED were measured.CE angle, AD , RA , LS , PED and JSW were the parameters observed to have statistically significant difference with respect to gender but
not with sides.
In CT abdomen and pelvis (50) (100 acetabula) (24 males, 26 females) (50 right and 50 left) CE angle, AD, AA, AIA, RA, ARO, EI, LS, DTW, AV, JSW, PED, AASA and PASA were measured.When statistically analyzed AD, RA, AA, LS, PED and JSW were the parameters observed to have significant difference with respect to gender but not with sides.
In 30 (15 males and 15 females) fetuses (12 to 40 weeks), the acetabular diameter, acetabular depth and shape of the acetabulum were measured. The diameter and depth of the acetabulum increased with the age of the fetuses and the shape of the acetabulum became less hemispherical as the age advanced, thereby the socket was converted into a shallow cavity. The results were statistically apprehended
Reduce the complexity of the E-learning authoring process
No full textFor every problem, there is one solution which is simple, neat, and wrong. The production of E-Learning contents is today the largest cost factor in the E-Learning and also the major issue of insecurity. This is an obstacle with the further propagation of the E-Learning. At present there are hardly visible numbers of tools to the production of E-Leaning contents. Besides the partial very high prices for this software they have the deficiency that they are usable only after a training course phase by the E-Learning author due to their complexity and its extent. The new challenge for designers and the researchers is to develop software tools for effective E-Learning. This Master thesis proposes an E-learning authoring tool which automatically uploads the file (OpenOffice document) which is selected by the enduser to the LMS/server. It also narrates how the content and the metadata are transformed as a SCORM package as well as its simplicity comparing to the other tools

Chemical and biological evaluation of Andrographis echioides leaf extracts collected from the Vellore district in Tamil Nadu, India
No full textAbstractThe chemical and biological activities of crude extracts of Andrographis echioides leaves using petroleum (pet) ether, ethyl acetate, methanol and aqueous solvents were assayed.The total phenol, flavonoid, protein and carbohydrate contents of A. echioides crude extracts were evaluated. The antioxidant activities of the leaf extracts were determined by 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), hydrogen peroxide, metal chelating, reducing power and total antioxidant activity assays. In addition, the crude extracts were screened for antibacterial activity (gram-positive and gram-negative bacteria) by disc diffusion method and the minimum inhibitory concentration was determined.Of the crude extracts tested, the pet ether extract of A. echioides contained more total phenols (0.01955 ± 0.0012 mg/g), flavonoids (1.2889 ± 0.3606 mg/g) and proteins (1.6065 ± 0.160 mg/mL). The aqueous extract of A. echioides was enriched for carbohydrate (467.6 ± 0.003 mg/mL). The methanol extract of A. echioides exhibited potent antioxidant activity IC50 values (1.14 ± 0.06 to 1.15 ± 0.45 μg/mL), as well as antibacterial activity (16 ± 1.527 mm), than the aqueous extract of A. echioides (20 ± 1.527 mm).A. echioides has great potential as a source of anti-cancer compounds due to its high antioxidant content and antibacterial activity
The degradation of silicone coatings in high temperature atmospheres
No full textTo evaluate the degradation of silicone based coatings that protect the mild steel surfaces from corrosion in high temperature atmospheres, the coatings were exposed to muffle furnace for heating ‐ cooling cycle (as per ASTM specification D 2485) up to 700°C. The ability of the paint film to withstand the temperature is related to its resistance as well as microcracks. These factors are very useful in precisely quantifying the degree of deterioration of the protective film. In the present work, two types of silicone based paints (silicone‐titanate, rhodorsil silicone) were prepared and the surface degradation of these coatings were studied by EIS technique and SEM with EDAX analysis. The chemical resistance properties were also analyzed.</jats:p
Generation and spectroscopic and kinetic characterization of methoxy-substituted phenoxyl radicals in solution and on paper
No full textA number of methoxy-substituted phenoxyl radicals have been generated and characterized by laser flash photolysis techniques in solution and on paper. The radicals have been produced by three routes in solution: hydrogen abstraction from phenols by tert-butoxyl radical, photolysis of ?-aryloxyacetophenones, and direct excitation of phenols. Most of the phenoxyl radicals studied have a characteristic absorption near 400 nm; the ortho-substituted radicals have an additional broad absorption in the visible in non-hydroxylic solvents (e.g., 650 nm for 2-methoxyphenoxyl radical). The relative intensities of the 400 nm and the long-wavelength bands vary with substitution pattern and solvent, with the long wavelength band being much weaker in hydroxylic solvents. Direct excitation of phenols provides an alternate source of phenoxyl radicals in some cases. However, for 4-methoxyphenol there are overlapping absorptions due to triplet phenol and phenol radical cation, both of which absorb in the 400-460 nm region. The 4-methoxyphenol radical cation is formed in a biphotonic process and decays by deprotonation to give the phenoxyl radical. The 4-methoxyphenoxyl radical can also be generated on paper from either the ketone or phenol precursor and decays with complex kinetics that depend on the precursor loading and laser intensity. There is no evidence for the formation of significant amounts of long-lived ketone or phenol triplets on paper. The decay kinetics for the phenoxyl radical are modified by the addition of the radical scavenger dithioerythritol. The results indicate both static and dynamic components to the radical scavenging process. The generation of phenoxyl radicals on paper in the presence and absence of scavengers provides the basis for the development of a new method for screening potential photoyellowing inhibitors and understanding their mode of action.On a g\ue9n\ue9r\ue9 un certain nombre de radicaux ph\ue9noxyles substitu\ue9s par des groupes m\ue9thoxyles et on les a caract\ue9ris\ue9s par les techniques de la photolyse laser \ue9clair en solution et sur papier. On a produit les radicaux par trois m\ue9thodes en solution: utilisation du radical tert-butyloxyle pour l'enl\ue8vement d'hydrog\ue9ne \ue0 partir de ph\ue9nols, la photolyse d' ?-aryloxyac\ue9toph\ue9nones et l'excitation directe de ph\ue9nols. La plupart des radicaux ph\ue9noxyles \ue9tudi\ue9s pr\ue9sentent une bande d'absorption caract\ue9ristique vers 400 nm; les radicaux substitu\ue9s en ortho pr\ue9sentent en plus une large bande d'absorption dans le visible dans les solvants non hydroxyliques (environ 650 nm pour le radical 2-m\ue9thoxyph\ue9noxyle). Les intensit\ue9s relatives des bandes \ue0 400 nm et \ue0 longueur d'onde plus \ue9lev\ue9e varient avec le patron de substitution et avec le solvant; la bande \ue0 longueur d'onde plus \ue9lev\ue9e est la plus faible dans les solvants hydroxyliques. Dans certains cas, l'excitation directe des ph\ue9nols est une voie alternative d'obtention de radicaux ph\ue9noxyles. Toutefois, pour le 4-m\ue9thoxyph\ue9nol, il y a superposition de bandes dues au ph\ue9nol triplet et au cation radical ph\ue9nol qui absorbent tous les deux dans la r\ue9gion de 400 \ue0 460 nm. Le cation radical 4-m\ue9thoxyph\ue9nol se forme par un processus biphotonique et il se d\ue9compose par d\ue9protonation pour donner le radical ph\ue9noxyle. Le radical 4-m\ue9thoxyph\ue9noxyle peut aussi \ueatre obtenu sur papier \ue0 partir soit de la c\ue9tone ou du ph\ue9nol appropri\ue9 et il se d\ue9compose avec une cin\ue9tique complexe qui d\ue9pend de la concentration du pr\ue9curseur et de l'intensit\ue9 du laser. Sur le papier, on n'a obtenu aucune indication pouvant sugg\ue9rer qu'il y a formation de quantit\ue9s appr\ue9ciables d'\ue9tats triplets de longue vie de c\ue9tone ou de ph\ue9nol. La cin\ue9tique de la d\ue9composition du radical ph\ue9noxyle est modifi\ue9e par l'addition du pi\ue9ge \ue0 radical dithio\ue9rythritol. La g\ue9n\ue9ration de radicaux ph\ue9noxyles sur papier, en pr\ue9sence ou en l'absence de pi\ue9ges \ue0 radicaux, fournit une base pour le d\ue9veloppement d'une nouvelle m\ue9thode d'\ue9valuer les inhibiteurs potentiels de jaunissement photochimique et de comprendre leur mode d'action.NRC publication: Ye
