We present the results of a new calculation of the photodisintegration of ultrahigh energy cosmic-ray (UHCR) nuclei in intergalactic space. The critical interactions for energy loss and photodisintegration of UHCR nuclei occur with photons of the 2.73 K cosmic background radiation (CBR) and with photons of the infrared background radiation (IBR). We have reexamined this problem making use of a ...

Despite the lack of randomised controlled trials and paucity of the published data, the current evidence suggests that the post-mastectomy radiation therapy (PMRT) does not represent a contraindication to skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) in the multidisciplinary setting. Although PMRT is associated with a higher incidence of complications, a satisfactory c...

The tutor for doing proofs in high school geometry consists of a cot of ideal and buggy rules (IRR), a tutor, and an interface. The IBR is responsible for eh iuer t l y computing matcher, to all the correct and incorrect rules The interface is responsible for interacting with the student and graphically representing the proof. The tutor is responsible for directing the IBR and interface to achi...

The present study involved in analysis of 81 sera samples collected from Murrah (34), Surti (20) and non-descript buffaloes (27) with history of respiratory and reproductive disorders for IBR antibodies by indirect Enzyme linked immunosorbent assay (ELISA), Virus neutralization test (VNT) and Passive haemagglutination assay (PHA). The immunological assays viz., indirect ELISA, VNT and PHA revea...

Most graphics applications today require more or less photorealistic scenes to be rendered. This can be quite easily accomplished by rendering 3D models with increasing complexity. However, despite the fact that geometric modeling can nowadays be hardware accelerated, photorealistic results need a lot of computing and thus interactivity is usually sacrificed. Therefore, in the last few years th...

Image-based rendering (IBR) has become a very active research area in recent years. The optimal sampling problem for IBR has not been completely solved. In this paper, we show that theoretically, the optimal sampling efficiency can be achieved by employing the generalized periodic sampling theory with arbitrary geometry. When there is no occlusion in the scene and the scene is Lambertian, we sh...

Place and role of nuclear analytical techniques (NATs) in life sciences is discussed. Examples of radioanalytical investigations at the IBR-2 pulsed fast reactor in Dubna illustrate the environmental, biomedical, geochemical and industrial applications of instrumental neutron activation analysis.

Questions concerning the role of nature and nurture in higher cognition appear to be intractable if one restricts one's attention to development in humans. However, in other domains, such as sensory development, much information has been gained from controlled rearing studies with animals. Here, we used a similar experimental strategy to investigate intuitive reasoning about occluded objects. N...

Strongly halogen-bonded complexes form between 4-alkoxyphenyl-4-pyridines and iodine as well the interhalogens ICl IBr. Examples are characterised by single crystal X-ray crystallography most show a liquid-crystalline SmA phase.
