Narayanella, a new name for Narayana Subba Rao (hymenoptera : mymaridae)
No full textThe name Narayana was applied (Subba Rao, 1976) to a genus erected for the new species N. pilipes reared from the gaUs of Lagerstoemia flos reginae. Unfortunately the author overlooked the vulid and prior use of Narayana by Distant (1908). Narayana Distant was erected with rusticitatus as type-species (Issidae: Homoptera). Hence Narayana Subba Rao is a junior homonym which has to be replaced according to the rules of the International Zoological Nomenclature

Material examined. INDIA: KARNATAKA: Bengaluru [formerly, Bangalore], Hebbal, 68 females (on 4 cards; 4 females on two slides), 20.iv. 2009, ex Ceroplastes sp., Coll. K. Veenakumari (Collection No. A. 573) (31 females in ZDAMU; 37 females returned to Dr. Veenakumari in NBAII). Comments. This species has not been reported since its original description based on 7 females (holotype and 6 paratypes) reared from Vinsonia stellifera Westwood (Hemiptera: Coccidae). The above listed specimens, reared from a species of Ceroplastes Gray (Hemiptera: Coccidae), were received from Dr. K. Veenakumari of the NBAII, Bengaluru. Because this beautiful species was described in detail with illustrations by Subba Rao (1980) and later redescribed and illustrated by Hayat (1998), I do not redescribe the species but for the first time provide photographs of the head, body and fore wing (Figs 22–24).Published as part of Hayat, Mohammad, 2012, Records and descriptions of some Aphelinidae (Hymenoptera: Chalcidoidea) from India, pp. 39-50 in Zootaxa 3521 on page 49, DOI: 10.5281/zenodo.21246
The biology and some aspects of morphology of the immature stages of Chelonus narayani Subba Rao (braconidae : hymenoptera)
No full textChelonus narayani Subba Rao is an egg-larval parasite of Heliothis armigera (Fabr.). The parasite has been liberated in U.S.A. and Hawaii for the control of Lepidopterous pests. A method for the mass-rearing of the parasite under laboratory conditions is described. A study of the morphology of immature stages has been made and the tracheal system is described in detail. The physiology of respiration and function of the anal vesicle is discussed

Preliminary estimates of tritium permeation and retention in the first wall of DEMO due to ion bombardment
No full textTritium self-sufficiency presents a critical engineering challenge for DEMO, requiring efficient breeding and extraction systems, as well as minimizing tritium losses to the surrounding systems, such as plasma-facing components, vacuum vessel, cooling system, etc. Structural and plasma-facing components will act as a tritium sink, as tritium will be accumulated in the bulk of these components due to energetic particle bombardment and may permeate out of the vacuum system. The design of the plasma-facing components will consequently directly influence the plant lifetime, operational safety and cost of any future power plant. Therefore, modeling of tritium retention and permeation in these components is required for the engineering designs of the tritium breeding and safety systems. In this work, the diffusion-transport code TESSIM-X is benchmarked against the well-established TMAP7 code and a comparison with a simplified DEMO-relevant test case is performed. The use of either code for modeling of DEMO conditions is discussed. Following this, TESSIM-X is used to provide a preliminary assessment of tritium permeation and retention in the DEMO first wall, based on the current WCLL (Water Cooled Lithium Lead) and HCPB (Helium Cooled Pebble Bed) breeding blanket designs
